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 by any Person 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 and in accordance with such reasonable rules as the Trustee may determine.

(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.

(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: Chief Legal Officer.

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.

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 4.02 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.

At the option of the Holder and subject to the other provisions of this Section 3.06, 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.

Neither the Company nor the Security Registrar shall be required to exchange or register a transfer of any Security (i) that has been surrendered for conversion or (ii) as to which a Fundamental Change Purchase Notice has been delivered and not withdrawn, except that where such Fundamental Change Purchase Notice provides that such Security is to be purchased only in part, the Company and the Security Registrar shall be required to exchange or register a transfer of the portion thereof not to be purchased.

(c) Neither the Trustee, the Security Registrar nor any of their respective 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 3.07. Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the Trustee, together with such security or indemnity as may be required by the Company or the Trustee to save each of them harmless, 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 and 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 ▇▇▇▇▇▇ and bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section 3.07, 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 3.07 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 3.08. Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee, the Security Registrar and any agent of the Company, the Trustee or the Security Registrar shall treat the Person in whose name such Security is registered on the Security Register as the owner of such Security for the purpose of receiving payment of the principal of such Security and for all other purposes whatsoever, and neither the Company, the Trustee, the Security Registrar nor any agent of the Company, the Trustee or the Security Registrar shall be affected by notice to the contrary.

Section 3.09. Global Securities; Transfer.

(a) Global Securities shall (i) be registered in the name of the Depositary or the nominee of such Depositary and (ii) be delivered to the Trustee as custodian for the Depositary. 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, 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 that a Holder is entitled to take under this Indenture or the Securities; and the Trustee or any agent of the Company or the Trustee shall give effect to any proxy or other authorization granted by the Depositary. This Indenture shall not impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of beneficial owners of a Global Security.

(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. Physical Securities shall be transferred to all beneficial owners in exchange for their beneficial interests in the Global Securities if (i) the Depositary has notified the Company and the Trustee in writing that the Depositary (A) is unwilling or unable to continue as Depositary for such Global Security or (B) 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, (ii) there shall have occurred and be continuing an Event of Default with respect to such Global Security and the Trustee has received a written request from the Depositary that Physical Securities be issued or (iii) 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.

In connection with the transfer of a Global Security to beneficial owners pursuant to this Section 3.09(b), 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.

(c) Notwithstanding Section 3.09(b), a portion of the principal amount of a Restricted Global Security may be exchanged or transferred for an equal principal amount of a Global Security that does not bear the legend set forth in Exhibit C-1 in accordance with Section 3.11. If such Restricted Security surrendered for transfer or exchange is represented by a Restricted Global Security, the principal amount of the Restricted Global Securities shall be reduced by the appropriate principal amount and the principal amount of a Global Security without the legend set forth in Exhibit C-1 hereto shall be increased by an equal principal amount. If a Global Security without the legend set forth in Schedule C- 1 is not then outstanding, the Company shall execute and the Trustee shall authenticate and deliver an unlegended Global Security to the Depositary.

Section 3.10. Cancellation. The Company at any time may deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder that 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, conversion (pursuant to Article 6 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.

Section 3.11. Restricted Securities; Restrictions on Transfer. (a) In connection with any transfer of Restricted Securities, the Holder must complete the assignment form set forth on the certificate representing the Securities. If the Holder has specified in the assignment form that the transfer will be made pursuant to Rule 144 under the Securities Act, the Company may require, prior to registering any such transfer of the Securities, in its sole discretion, the Holder to provide such legal opinions, certifications and other information as the Company may reasonably request to confirm that such transfer is being made pursuant to Rule 144.

(b) Any Securities that are Restricted Securities and as to which such restrictions on transfer shall have expired in accordance with their terms or which have been transferred in accordance with Rule 144 or pursuant to an effective registration statement under the Securities Act may, upon surrender of such Securities for exchange or transfer to the Registrar in accordance with the provisions of Section 3.06, be exchanged for a new Security or Securities, of like tenor and aggregate principal amount, which shall not bear the restrictive legend set forth in Exhibit C-1 hereto.

Section 3.12. 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.

(i) that it will hold all sums held by it as such agent for the payment of the principal of or interest, including Additional Interest, if any, on the Securities (whether such sums have been paid to it by the Company or by any other obligor on the Securities) in trust for the benefit of the Holders of the Securities;

The Company shall, on or before each due date of the principal of or interest, including Additional Interest, if any, on the Securities, deposit with the paying agent a sum (in funds which are immediately available on the due date for such payment) sufficient to pay such principal or interest, including Additional Interest, if any, and (unless such paying agent is the Trustee) the Company will promptly notify the Trustee in writing of any failure to take such action; provided that if such deposit is made on the due date, such deposit shall be received by the paying agent by 11:00 a.m. New York City time, on such date.

(b) If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal of or interest, including Additional Interest, if any, on the Securities, set aside, segregate and hold in trust for the benefit of the Holders of the Securities a sum sufficient to pay such principal or interest, including Additional Interest, if any, so becoming due and will promptly notify the Trustee of any failure to take such action and of any failure by the Company (or any other obligor under the Securities) to make any payment of the principal of or interest, including Additional Interest, if any, on the Securities when the same shall become due and payable.

(c) Anything in this Section 4.03 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or any paying agent hereunder as required by this Section 4.03, such sums to be held by the Trustee upon the trusts herein contained and upon such payment by the Company or any paying agent to the Trustee, the Company or such paying agent shall be released from all further liability with respect to such sums.

(d) Anything in this Section 4.03 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section 4.03 is subject to Section 12.03 and Section 12.04.

The Trustee shall not be responsible for the actions of any other paying agents (including the Company if acting as its own paying agent) and shall have no control of any funds held by such other paying agents.

Section 4.04. Rule 144A Information Requirement. Within the period prior to the expiration of the holding period applicable to sales thereof under Rule

144(k) under the Securities Act (or any successor provision), the Company covenants and agrees that it shall, during any period in which it is not subject to Section 13 or 15(d) under the Exchange Act, make available to any Holder or beneficial holder of Restricted Securities or any Common Stock bearing the legend set forth in Exhibit C-2 hereto in connection with any sale thereof and any prospective purchaser of the Securities or Common Stock designated by such Holder or beneficial holder, the information required pursuant to Rule 144A(d)(4) under the Securities Act upon the request of any Holder or beneficial holder of the Securities or such Common Stock, all to the extent required from time to time to enable such Holder or beneficial holder to sell its Securities or Common Stock without registration under the Securities Act within the limitation of the exemption provided by Rule 144A, as such rule may be amended from time to time.

Section 4.05. Resale of Restricted Securities. During the period beginning on the first date of issuance of the Securities and ending on the date that is two years thereafter, the Company shall not, and shall not permit any of its “affiliates” within its “control” (each as defined under Rule 144 under the Securities Act or any successor provision thereto) to, resell any Securities which constitute “restricted securities” under Rule 144 that have been reacquired by any of them.

Subject to the requirements of Section 314(a) of the Trust Indenture Act, the Company will deliver to the Trustee within 30 days after the Company is required to file the same with the Commission, copies of the quarterly and annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the Commission may prescribe) which the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, and shall otherwise comply with the requirements of Section 314(a) of the Trust Indenture Act. To the extent any such information, documents and reports are filed by the Company electronically on the Commission’s Electronic Data Gathering and Retrieval System (or any successor system), notice thereof shall be delivered promptly to the Trustee, upon which such information, documents and reports shall be deemed delivered to the Trustee.

Section 4.07. Book-Entry System. If the Securities cease to trade in the Depositary’s book-entry settlement system, the Company covenants and agrees that it shall use reasonable efforts to make such other book-entry arrangements that it determines are reasonable for the Securities, which arrangements shall be acceptable to the Trustee.

Section 4.08. Additional Interest under the Registration Rights Agreement. If at any time Additional Interest becomes payable by the Company

pursuant to the Registration Rights Agreement, the Company shall promptly deliver to the Trustee a certificate to that effect and stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable pursuant to the terms of the Registration Rights Agreement. Unless and until a Responsible Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry that no Additional Interest is payable.

At the Company’s request, the Trustee shall give such Fundamental Change Company Notice to each Holder in the Company’s name and at the Company’s expense; provided, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company.

No failure of the Company to give the foregoing notices and no defect therein shall limit the Securityholders’ purchase rights or affect the validity of the proceedings for the purchase of the Securities pursuant to this Section 5.01.

(c) No Purchase During Events of Default. There shall be no purchase of any Securities pursuant to this Section 5.01 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 Fundamental Change Purchase Notice) and is continuing an Event of Default of which the Trustee shall have received written notice (other than a default that is cured by the payment of the Fundamental Change Purchase Price of the Securities). The Paying Agent will promptly return to the respective Holders thereof any Securities (i) with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with this Indenture, or (ii) surrendered to it during the continuance of an Event of Default of which the Trustee shall have received written notice (other than a default that is cured by the payment of the Fundamental Change Purchase Price with respect to such Securities) in which case, upon such return, the Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn.

provided that if Physical Securities have not been issued, the notice must comply with appropriate procedures of the Depositary.

Section 5.04. Deposit of Fundamental Change Purchase Price. Prior to 10:00 a.m. (local time in The City of New York) on the Fundamental Change Purchase Date, subject to extension to comply with applicable law, the Company shall deposit 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 Fundamental Change Purchase Price, of all the Securities or portions thereof that are to be purchased as of the Fundamental Change Purchase Date. The Company shall promptly notify the Trustee in writing of the amount of any deposits of cash made pursuant to this Section 5.04. If the Paying Agent holds cash or securities sufficient to pay the Fundamental Change Purchase Price of any Security for which a Fundamental Change Purchase Notice has been tendered and not withdrawn in accordance with this Indenture as of the Business Day following the Fundamental Change Purchase Date, then effective on the Fundamental Change Purchase Date, (a) such Security shall cease to be outstanding and interest, including Additional Interest, if any, will cease to accrue thereon and (b) all other rights of the Holder in respect thereof will terminate (other than the right to receive the Fundamental Change Purchase Price and previously accrued and unpaid interest, including Additional Interest, if any, upon delivery or book-entry transfer of such Security, or interest payable on the related Interest Payment Date, if the Fundamental Change Purchase Date occurs between the Record Date and such Interest Payment Date, as applicable).

Section 5.05. Securities Purchased in Whole or in Part. Any Physical Security that is to be purchased, 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 ▇▇▇▇▇▇’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 purchased.

Section 5.06. Covenant to Comply With Securities Laws Upon Purchase of Securities. In connection with any offer to purchase Securities under Section 5.01 (provided that such offer or purchase 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 purchase), 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 5.01 to be exercised in the time and in the manner specified in Section 5.01.

Section 5.07. Repayment to the Company. The Trustee and the Paying Agent shall return to the Company any cash that remains unclaimed, together with interest, including Additional Interest, if any, or dividends, if any, thereon, held by them for the payment of the Fundamental Change Purchase Price; provided that to the extent that the aggregate amount of cash deposited by the Company pursuant to Section 5.04 exceeds the aggregate Fundamental Change Purchase Price of the Securities or portions thereof which the Company is obligated to purchase as of the Fundamental Change Purchase Date, then as soon as practicable following the Fundamental Change Purchase Date, the Trustee or the Paying Agent, as the case may be, shall return any such excess to the Company.

ARTICLE 6

CONVERSION

Section 6.01. Right to Convert.

(a) Subject to and upon compliance with the provisions of this Indenture, each Holder shall have the right, at such Holder’s option, to convert the

Securities, or any portion of such Securities in a Principal Amount which is $1,000 or a multiple of $1,000 thereof at the Conversion Rate then in effect, (x) on or after February 19, 2014 through the close of business on the third Business Day immediately preceding the Stated Maturity or (y) prior to the close of business on the Business Day immediately preceding February 19, 2014, but only upon the satisfaction of any of the following conditions and only during the periods set forth below:

(i) A Holder may surrender all or a portion of its Securities for conversion during any fiscal quarter (and only during such fiscal quarter) commencing after May 31, 2007, if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding fiscal quarter is greater than or equal to 130% of the Conversion Price in effect on each applicable Trading Day.

(ii) A Holder may surrender its Securities for conversion during the five Business Day period after any 10 consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 Principal Amount of Securities, as determined following a request by a Holder in accordance with the procedures set forth in this Section 6.01(a)(ii), for each day of such period was less than 97% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate on each such day. In connection with any conversion in accordance with this Section 6.01(a)(ii), the Bid Solicitation Agent shall have no obligation to determine the Trading Price of the Securities unless requested by the Company; and the Company shall have no obligation to make such request unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 Principal Amount of Securities would be less than 97% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate. Promptly after receiving such evidence, the Company shall instruct the Bid Solicitation Agent to determine the Trading Price of the Securities beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 Principal Amount of Securities is greater than or equal to 97% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate. If the Company does not so instruct the Bid Solicitation Agent to obtain bids when required, the Trading Price per $1,000 Principal Amount of Securities will be deemed to be less than 97% of the product of the last reported sale price and the applicable conversion rate on each day the Company fails to do so. If the Trading Price condition in the first sentence of this Section 6.01(a)(ii) has been met, the Company shall so notify the Holders. If, at any time after the Trading Price condition has been met, the Trading Price per $1,000 Principal Amount of Securities is greater than 97% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate for such date, the Company shall so notify the Holders.

(iii) If the Company elects to:

(A) issue to all or substantially all holders of Common Stock rights entitling them to purchase, for a period expiring within 60 days after the date of the distribution, shares of Common Stock at less than the average of the Last Reported Sale Prices of a share of Common Stock for the 10 consecutive Trading Day period ending on the Business Day preceding the announcement of such issuance; or

(B) distribute to all or substantially all holders of Common Stock assets, debt securities or rights to purchase securities of the Company, which distribution has a per share value, as reasonably determined by the Company’s Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Business Day preceding the declaration date for such distribution,

then, in each case, the Company shall notify the Holders, in the manner provided in Section 1.06, at least 25 Scheduled Trading Days prior to the Ex-Dividend Date for such distribution. Once the Company has given such notice, Holders may surrender Securities for conversion at any time until the earlier of 5:00 p.m., New York City time, on the Business Day immediately prior to such Ex-Dividend Date or the Company’s announcement that such distribution will not take place, even if the Securities are not otherwise convertible at such time.

(iv) (A) If the Company is party to a transaction described in clause (2) of the definition of Fundamental Change (without, for the avoidance of doubt, giving effect to the exception in the last paragraph of the definition thereof relating to Publicly Traded Securities), the Company shall notify Holders, in the manner provided in Section 1.06, at least 47 Scheduled Trading Days prior to the anticipated effective date for such transaction. Once the Company has given such notice, Holders may surrender Securities for conversion at any time until 15 calendar days after the actual effective date of such transaction (or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Purchase Date, if later).

(B) In addition, if a Fundamental Change of the type described in clauses (1) and (4) in the definition thereof occurs,

Holders may surrender all or a portion of their Securities for conversion at any time beginning on the actual effective date of such Fundamental Change until and including the date that is 30 calendar days after the actual effective date of such transaction or, if later, until the related Fundamental Change Purchase Date.

(b) Notwithstanding the foregoing, a Security in respect of which a Holder has delivered a Fundamental Change Purchase Notice exercising such Holder’s option to require the Company to purchase such Security may be surrendered for conversion only if such notice of exercise is withdrawn in accordance with Article 5 hereof prior to 10:00 a.m., New York City time, on the Business Day immediately preceding the Fundamental Change Purchase Date.

Section 6.02. Conversion Procedure.

(a) Each Security shall be convertible at the office of the Conversion Agent.

(b) In order to exercise the conversion privilege with respect to any beneficial interest in a Global Security, the Holder must complete the appropriate instruction form for conversion pursuant to the Depositary’s book-entry conversion program, furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or Conversion Agent, and pay the funds, if any, required by Section 6.03(f) and any transfer taxes if required pursuant to Section 6.08 and the Trustee or Conversion Agent must be informed in writing of the conversion in accordance with customary practice of the Depositary. In order to exercise the conversion privilege with respect to any Securities in certificated form that are not Global Securities, the Holder of any such Securities to be converted, in whole or in part, shall:

(i) complete and manually sign the conversion notice provided on the back of the Security (the “Conversion Notice”) or a facsimile of the conversion notice and deliver such Conversion Notice, which is irrevocable, to the Conversion Agent;

(ii) surrender the Security to the Conversion Agent;

(iii) if required, furnish appropriate endorsements and transfer documents;

(iv) if required, pay any transfer or similar taxes; and

(v) if required, make any payment required under Section 6.03(f).

The date on which the Holder satisfies all of the applicable requirements set forth above is the “Conversion Date.” The Trustee will, as promptly as possible, and in any event within two (2) Business Days, provide the Company with notice of any conversion exercises by Holders of which a Responsible Officer becomes aware.

(c) Each Conversion Notice shall state the name or names (with address or addresses) in which any certificate or certificates for shares of Common Stock which shall be issuable on such conversion shall be issued. All such Securities surrendered for conversion shall, unless the shares issuable on conversion are to be issued in the same name as the registration of such Securities, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or his duly authorized attorney.

(d) On the third Business Day immediately following the last day of the Observation Period, subject to compliance with any restrictions on transfer if shares issuable on conversion are to be issued in a name other than that of the Holder (as if such transfer were a transfer of the Securities (or portion thereof) so converted), the Company shall issue and shall deliver to such Holder at the office of the Conversion Agent, a check or cash and a certificate or certificates for the number of full shares of Common Stock issuable in accordance with the provisions of this Article 6, if applicable. In case any Securities of a denomination greater than $1,000 shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Securities so surrendered, without charge to him, new Securities in authorized denominations in an aggregate Principal Amount equal to the unconverted portion of the surrendered Securities.

Each conversion shall be deemed to have been effected as to any such Securities (or portion thereof) on the date on which the requirements set forth above in this Section 6.02 have been satisfied as to such Securities (or portion thereof), and the person in whose name any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall be deemed to have become on said date the holder of record of the shares represented thereby; provided that in case of any such surrender on any date when the stock transfer books of the Company shall be closed, the person or persons in whose name the certificate or certificates for such shares are to be issued shall be deemed to have become the record holder thereof for all purposes on the next day on which such stock transfer books are open, but such conversion shall be at the Conversion Price in effect on the date upon which such Securities shall be surrendered; provided further, that a Holder receiving shares of Common Stock upon conversion will not be entitled to any rights as a holder of Common Stock, including, among other things, the right to vote and receive dividends and notices of stockholder meetings, until the close of business on the last Trading Day of the Observation Period.

(e) Upon the conversion of an interest in Global Securities, the Trustee (or other Conversion Agent appointed by the Company) shall make a notation on such Global Securities as to the reduction in the Principal ▇▇▇▇▇▇ represented thereby. The Company shall notify the Trustee in writing of any conversions of Securities effected through any Conversion Agent other than the Trustee.

(f) Each stock certificate representing Common Stock issued upon conversion of the Securities that are Restricted Securities shall bear the legend in substantially the form of Exhibit C-2 hereto.

Section 6.03. Settlement of Conversion Obligation.

(a) The Company shall satisfy its obligation to convert the Securities at the Conversion Rate in the manner set forth in this Section 6.03.

(b) The Company shall satisfy its conversion obligations in respect of any Security on the third Business Day following the final Trading Day of the applicable Observation Period.

(c) Upon conversion, the Company will deliver to the Holders, in respect of each $1,000 Principal Amount of Securities being converted, a “Settlement Amount” equal to the sum of the Daily Settlement Amounts for each of the 45 Trading Days during the Observation Period for such Security.

(d) The “Daily Settlement Amount” for each of the 45 Trading Days during the Observation Period shall consist of:

(i) cash equal to the lesser of (x) one-forty-fifth of $1,000 and (y) the Daily Conversion Value for such Trading Day, and

(ii) to the extent the Daily Conversion Value exceeds one-forty-fifth of $1,000, a number of shares of Common Stock equal to (x) the difference between the Daily Conversion Value and one-forty-fifth of $1,000, divided by (y) the Daily VWAP for such day.

(e) Subject to clauses (f) and (g) below, upon conversion, Holders shall not receive any separate cash payment for accrued and unpaid interest, including Additional Interest, if any, unless such conversion occurs between a Record Date and the Interest Payment Date to which it relates.

(f) If Securities are converted after 5:00 p.m., New York City time, on a regular Record Date for the payment of interest, Holders of such Securities at 5:00 p.m., New York City time, on such Record Date will receive the interest and Additional Interest, if any, payable on such Securities on the corresponding Interest Payment Date notwithstanding the conversion. Securities surrendered for conversion during the period from 5:00 p.m., New York City time, on any Record

Date to 9:00 a.m., New York City time, on the immediately following Interest Payment Date, must be accompanied by funds equal to the amount of interest and Additional Interest, if any, payable on the Securities so converted; provided that no such payment need be made (i) for conversions following the Record Date immediately preceding the Stated Maturity; (ii) if the Company has specified a Fundamental Change Purchase Date that is after a Record Date and on or prior to the third Trading Day after the corresponding Interest Payment Date; or (iii) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Security.

(g) If a Holder converts some or all of its Securities into Common Stock when Additional Interest is accruing on the Securities being converted, the Holder will not be entitled to receive Additional Interest with respect to any Common Stock issued in respect of the Securities converted. Such Holder will receive, on the third Business Day following the last day of the related Observation Period, all accrued and unpaid Additional Interest to the Conversion Date.

(h) The Company shall not issue fractional shares of Common Stock upon conversion of Securities. If multiple Securities shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion shall be computed on the basis of the aggregate Principal Amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share of stock would be issuable upon the conversion of any Securities, the Company shall make payment therefor in cash in lieu of fractional shares of Common Stock based on the Daily VWAP of the Common Stock on the final Trading Day of the applicable Observation Period.

(i) For purposes of this Section 6.03, and notwithstanding the definitions contained in Section 1.01, “Trading Day” means a day on which (i) there is no Market Disruption Event and (ii) trading in the Common Stock generally occurs on the New York Stock Exchange or, if the Common Stock is not then listed on the New York Stock Exchange, on the principal other U.S. national or regional securities exchange on which the Common Stock is then listed or, if the Common Stock is not then listed on a U.S. national or regional securities exchange, on the principal other market on which the Common Stock is then traded. If the Common Stock (or other security for which a Daily VWAP must be determined) is not so listed or quoted, “Trading Day” means a Business Day.

(j) The Company’s delivery to a Holder of cash or a combination of cash and shares of Common Stock, as the case may be, together with any cash payment for any fractional share, into which a Security is convertible, will be deemed to satisfy in full the Company’s obligation to pay (i) the Principal Amount of such Security; and (ii) accrued and unpaid interest and Additional Interest, if any, to, but not including, the Conversion Date. As a result, accrued and unpaid interest and Additional Interest, if any, to, but not including, the Conversion Date will be deemed to be paid in full rather than cancelled, extinguished or forfeited.

Section 6.04. Adjustment of Conversion Rate. Subject to Section 6.04(m), the Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs.

(a) If the Company, at any time or from time to time while any of the Securities are outstanding, exclusively issues shares of Common Stock as a dividend or distribution on shares of Common Stock, or if the Company effects a share split or share combination, then the Conversion Rate will be adjusted based on the following formula:


		CR' = CR₀ x		OS'
		CR' = CR₀ x		OS₀


where

CR'	=	the Conversion Rate in effect immediately after the Ex-Dividend Date or effective date;

CR₀	=	the Conversion Rate in effect immediately prior to the Ex-Dividend Date of such dividend or distribution, or the effective date of such share split or share combination, as applicable;

OS'	=	the number of shares of Common Stock outstanding prior to such Ex-Dividend Date or effective date after giving effect to such dividend, distribution, share split or share combination; and

OS₀	=	the number of shares of Common Stock outstanding immediately prior to such Ex-Dividend Date or effective date.

If any dividend or distribution of the type described in this Section 6.04(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate which would then be in effect if such dividend or distribution had not been declared.

(b) If the Company, at any time or from time to time while any of the Securities are outstanding, issues to all or substantially all holders of Common Stock any rights or warrants entitling them for a period of not more than 60 calendar days to subscribe for or purchase shares of Common Stock at a price per

share less than the average of the Last Reported Sale Prices of Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be adjusted based on the following formula:


		CR' = CR₀ x		OS₀ + X
		CR' = CR₀ x		OS₀ + Y


where

CR'	=	the Conversion Rate in effect immediately after the Ex-Dividend Date for such issuance;

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

OS₀	=	the number of shares of Common Stock outstanding immediately after such Ex-Dividend Date;

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 Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of the issuance of such rights or warrants.

To the extent such rights or warrants are not exercised prior to their expiration or termination, the Conversion Rate shall be readjusted to the Conversion Rate which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock actually delivered. If such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if the date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than the average of the Last Reported Sale Prices of Common Stock for the 10 consecutive Trading Day period ending on the Business Day immediately preceding the date of announcement of such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants and the value of such consideration, if other than cash, as shall be determined in good faith by the Board of Directors of the Company.

(c) If the Company, at any time or from time to time while the Securities are outstanding, distributes shares of any class of Capital Stock of the Company, evidences of Indebtedness or other assets or property of the Company to all or substantially all holders of its Common Stock, excluding:

(i) dividends or distributions referred to in Section 6.04(a);

(ii) rights or warrants referred to in Section 6.04(b);

(iii) dividends or distributions paid exclusively in cash; and

(iv) Spin-Offs (as defined below) to which the provisions set forth below in this clause 6.04(c) shall apply;

then the Conversion Rate will be adjusted based on the following formula:


		CR' = CR₀ x		SP₀
		CR' = CR₀ x		SP₀ – FMV


where

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

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

SP₀	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 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 one share of the Common Stock on the record date for such distribution.

If the Board of Directors of the Company determines the Fair Market Value of any distribution for purposes of this Section 6.04(c) 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 average of the Last Reported Sale Prices of the Common Stock.

With respect to an adjustment pursuant to this Section 6.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of

shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit (a “Spin-Off”), the Conversion Rate in effect immediately before 5:00 p.m., New York City time, on the effective date of the Spin-Off shall be increased based on the following formula:


		CR' = CR₀ x		FMV₀ + MP₀
		CR' = CR₀ x		MP₀


where

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

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

FMV₀	=	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock over the first ten consecutive Trading Day period after, and including, the effective date of the Spin-Off; and

MP₀	=	the average of the Last Reported Sale Prices of Common Stock over the first ten consecutive Trading Day period after, and including, the effective date of the Spin-Off.

The adjustment to the Conversion Rate under the preceding paragraph will occur on the tenth Trading Day from, and including, the effective date of the Spin-Off; provided that in respect of any conversion within the 10 Trading Days immediately following, and including, the effective date of any Spin-Off, references within this Section 6.04(c) to “10 Trading Days” shall be deemed replaced with such lesser number of Trading Days as have elapsed between the effective date of such Spin-Off and the Conversion Date in determining the applicable Conversion Rate.

(d) If any cash dividend or other distribution is made to all or substantially all holders of Common Stock, the Conversion Rate shall be adjusted based on the following formula:


		CR' = CR₀ x		SP₀
		CR' = CR₀ x		SP₀ – C


where

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


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

SP₀	=	the Last Reported Sale Price of a share of Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and

C	=	the amount in cash per share the Company distributes to holders of Common Stock.

(e) If the Company or any Subsidiary makes a payment in respect of a tender offer or exchange offer for Common Stock, 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 per share of Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula:


		CR' = CR₀ x		AC + (SP' x OS')
		CR' = CR₀ x		OS₀ x SP'


where

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

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

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

SP	=	the average of the Last Reported Sale Prices of Common Stock over the 10 consecutive Trading Day period commencing on the Trading Day next succeeding the date such tender or exchange offer expires;

OS'	=	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires; and

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

The adjustment to the Conversion Rate under this Section 6.04(e) shall occur on the tenth Trading Day from, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any conversion within the 10 Trading Days beginning on the Trading Day next succeeding the date the tender or exchange offer expires, references within this Section 6.04(e) to “10 Trading Days” shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Trading Day next succeeding the date the tender or exchange offer expires and the Conversion Date in determining the applicable Conversion Rate.

If the Company is obligated to purchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange had not been made.

(f) No adjustment to the Conversion Rate will be required unless the adjustment would require an increase or decrease of at least 1% of the Conversion Rate. If the adjustment is not made because the adjustment does not change the Conversion Rate by at least 1%, then the adjustment that is not made will be carried forward and taken into account in any future adjustment. All required calculations will be made to the nearest cent or 1/1000th of a share of Common Stock, as the case may be.

(g) For purposes of this Section 6.04, “record date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

(h) The Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 days if the Board of Directors shall have made a determination that such increase would be in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion Rate is increased pursuant to this Section 6.04(h), the Company shall mail to Holders of record of the Securities a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(i) The Company may (but is not required to) make such increases in the Conversion Rate, in addition to any adjustments required by Section 6.04(a), 6.04(b), 6.04(c), 6.04(d), 6.04(e) or 6.04(h), as the Board of Directors considers to

be advisable to avoid or diminish income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with any dividend or distribution of shares (or rights to acquire shares) or from any event treated as such for income tax purposes.

(j) All calculations under this Article 6 shall be made by the Company. No adjustment shall be made for the Company’s issuance of Common Stock or securities convertible into or exchangeable for shares of Common Stock or rights to purchase Common Stock or convertible or exchangeable securities, other than as provided in this Section 6.04.

(k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion Agent an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate to each Securityholder at such Holder’s last address appearing on the list of Securityholders provided for in Section 3.06, within 20 days after execution of the related Officers’ Certificate. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(l) For purposes of this Section 6.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

(m) No adjustment to the Conversion Rate shall be made pursuant to this Section 6.04 if the Holders of the Securities may participate without conversion of their Securities in the transaction that would otherwise give rise to an adjustment pursuant to this Section 6.04 at the same time as holders of Common Stock and on the same terms as holders of Common Stock as if the Holders of the Securities held a number of shares of Common Stock equal to the Conversion Rate multiplied by the principal amount (expressed in thousands) of the Securities held by the Holders.

(n) Notwithstanding the foregoing, if the application of the foregoing formulas would result in a decrease in the Conversion Rate (other than as a result of a stock split or a stock dividend), no adjustment to the Conversion Rate shall be made.

(o) Notwithstanding anything to the contrary in this Article 6, no adjustment to the Conversion Rate shall be made:

(i) 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 the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan;

(ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any Subsidiary;

(iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in (ii) above outstanding as of the date the Securities were first issued;

(iv) for a change in the par value of the Common Stock;

(v) for accrued and unpaid interest, including Additional Interest, if any; or

(vi) for the avoidance of doubt, for the issuance of Common Stock by the Company (other than to all or substantially all holders of Common Stock) or the payment of cash by the Company upon conversion or repurchase of Securities.

Section 6.05. Adjustments of Average Prices. Whenever a provision of this Indenture requires the calculation of an average of Last Reported Sale Prices or Daily VWAP over a span of multiple days, the Company shall make appropriate adjustments to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date of the event occurs, at any time during the period from which the average is to be calculated.

Section 6.06. Adjustments Upon Certain Fundamental Changes.

(a) If (i) a Holder elects to convert Securities as described in Section 6.01(a)(iv) in connection with a corporate transaction as specified thereunder and such corporate transaction constitutes a Fundamental Change described in clause (1) or (2) of the definition thereof, the Conversion Rate will be increased by an

additional number of shares of Common Stock (the “Additional Shares”) as described below. Any conversion will be deemed to have occurred “in connection with” such Fundamental Change only if such Securities are surrendered for conversion at a time when the Securities would be convertible in light of the expected or actual occurrence of a Fundamental Change and notwithstanding the fact that a Security may then be convertible because another condition to conversion has been satisfied.

(b) The number of Additional Shares by which the Conversion Rate will be increased will be determined by reference to the table attached as Schedule I hereto, based on the date on which the Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid per share of Common Stock in the Fundamental Change. If the Fundamental Change is a transaction described in clause (2) of the definition thereof, and holders of Common Stock receive only cash in such Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of Common Stock over the five Trading Day period ending on the Trading Day preceding the Effective Date of the Fundamental Change.

(c) The Stock Prices set forth in the first row of the table in Schedule I hereto (i.e., column headers) shall be adjusted as of any date on which the Conversion Rate of the Securities is otherwise adjusted. 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 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 will be adjusted in the same manner as the Conversion Rate as set forth in Section 6.04.

(d) The table in Schedule I hereto sets forth the number of Additional Shares to be added to the Conversion Rate per $1,000 Principal Amount of Securities at the Stock Prices and Effective Dates set forth therein. The exact Stock Price and Effective Date for a Fundamental Change may not be set forth in the table in Schedule I, in which case:

(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 will 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 $110.00 per share (subject to adjustment in the same manner as the Conversion Rate as set forth in Section 6.04), no Additional Shares will be added to the Conversion Rate.

(iii) If the Stock Price is less than $45.54 per share (subject to adjustment in the same manner as the Conversion Rate as set forth in Section 6.04), no Additional Shares will be added to the Conversion Rate.

Notwithstanding the foregoing, in no event will the total number of shares of Common Stock issuable upon conversion exceed 21.9587 shares of Common Stock per $1,000 Principal Amount of Securities, subject to adjustments in the same manner as the Conversion Rate as set forth in Section 6.04.

Section 6.07. Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale. If any of the following events occur:

(i) any recapitalization, 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 6.04(c));

(ii) any consolidation, 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 recapitalization, 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

(iii) any sale, lease or other transfer of all or substantially all of the consolidated properties and assets of the Company and its Subsidiaries to any other Person or any statutory share exchange;

in each case of clauses (i) – (iii) as a result of which holders of Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash or any combination of the foregoing) with respect to or in exchange for such Common Stock, then at the effective time of such transaction, the Company or the successor or purchasing person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) providing that each $1,000 principal amount of Securities shall be convertible into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) receivable upon such recapitalization, reclassification, change, consolidation, merger, combination, sale, lease, transfer or exchange by a holder of a number of shares of

Common Stock equal to the Conversion Rate immediately prior to such recapitalization, reclassification, change, consolidation, merger, combination, sale, lease, transfer or exchange (the “Reference Property”). If the transaction causes Common Stock to be converted into the right to receive more than a single type of consideration (determined based in part upon any from of stockholder election), the Reference Property into which the Securities will be convertible shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such election. However, at and after the effective time of the transaction, the Company will continue to satisfy its conversion obligations in respect of the Securities by delivering (a) cash up to the aggregate principal amount of the Securities converted and (b) in lieu of Common Stock otherwise deliverable, the Reference Property that holders of the Common Stock would have received, in each case in accordance with the procedures set forth under Section 6.03. The amount of cash and any Reference Property that Holders receive upon conversion will be based on a Daily Conversion Value and a Daily Settlement Amount determined using the value of the Reference Property (using a volume weighted average method) during the applicable Observation Period in lieu of Daily VWAP. The Company shall not become a party to any such transaction unless its terms are consistent with this Section 6.07. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 6. If, in the case of any such recapitalization, reclassification, change, consolidation, merger, combination, sale, lease, transfer or exchange, the Reference Property receivable thereupon by a holder of Common Stock includes shares of stock, other securities or other property or assets (including cash or any combination thereof) of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, consolidation, merger, combination, sale, lease, transfer or exchange, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing.

The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the register of the Securities maintained by the Security Registrar, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The above provisions of this Section shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. If this Section 6.07 applies to any event or occurrence, Section 6.04 shall not apply.

Section 6.08. Taxes on Shares Issued. Any issue of stock certificates on conversions of Securities shall be made without charge to the converting Holder for any documentary, transfer, stamp or any similar tax in respect of the issue

thereof, and the Company shall pay any and all documentary, stamp or similar issue or transfer taxes that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the Holder of any Securities converted, and the Company shall not be required to issue or deliver any such stock certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

Section 6.09. Reservation of Shares; Shares to be Fully Paid; Compliance With Governmental Requirements; Listing of Common Stock. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of the Securities from time to time as such Securities are presented for conversion (assuming that, at the time of the computation of such number of shares or securities, all such Securities would be held by a single Holder).

Before taking any action that would cause an adjustment increasing the Conversion Rate to an amount that would cause the Conversion Price to be reduced below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Securities, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such Common Stock at such adjusted Conversion Price.

The Company covenants that all shares of Common Stock that may be issued upon conversion of Securities shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any tax, lien or charge (other than those created by the Holder).

The Company shall use its reasonable efforts to list or cause to have quoted any shares of Common Stock to be issued upon conversion of Securities on each national securities exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted.

Section 6.10. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Securityholder to determine the Conversion Rate or whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent

shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at any time be issued or delivered upon the conversion of any Securities; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Securities for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 6. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 6.07 relating either to the kind or amount of shares of stock or securities or property (including cash or any combination thereof) receivable by Holders upon the conversion of their Securities after any event referred to in such Section 6.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 10.01, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto.

Section 6.11. Notice to Holders Prior to Certain Actions. In case:

(a) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Conversion Rate pursuant to Section 6.04; or

(b) the Company shall authorize the granting to the holders of all of its Common Stock of rights or warrants to subscribe for or purchase any share of any class of its capital stock or any other rights or warrants; or

(c) of any reclassification or reorganization of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale, lease or transfer of all or substantially all of the assets of the Company or any of its Significant Subsidiaries; or

(d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company or any of its Significant Subsidiaries;

then, in each case, the Company shall cause to be filed with the Trustee and the Conversion Agent and to be mailed to each Securityholder at such Holder’s

address appearing on the list of Securityholders provided for in Section 3.06 of this Indenture, as promptly as practicable but in any event at least 15 days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights or warrants are to be determined, or (y) the date on which such reclassification, reorganization, consolidation, merger, sale, lease, transfer, dissolution, liquidation or winding up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, reorganization, consolidation, merger, sale, lease, transfer, dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, reorganization, consolidation, merger, sale, lease, transfer, dissolution, liquidation or winding up.

Section 6.12. Stockholder Rights Plan; Contingent Rights and Warrants. (a) Each share of Common Stock issued upon conversion of Securities pursuant to this Article 6 shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any stockholder rights plan adopted by the Company, as the same may be amended from time to time. If at the time of conversion, however, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights agreement so that the Holders of the Securities would not be entitled to receive any rights in respect of Common Stock issuable upon conversion of the Securities, the Conversion Rate will be adjusted at the time of separation as if the Company had distributed to all holders of Common Stock, shares of Capital Stock of the Company, evidence of indebtedness or assets as provided in Section 6.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

(b) Rights or Warrants distributed by the Company to all holders of Common Stock entitling them to subscribe for or purchase shares of the Company’s capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (a “Trigger Event”): (1) are deemed to be transferred with such shares of Common Stock; (2) are not exercisable; and (3) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of Section 6.04(b) or Section 6.04(c), (and no adjustment to the Conversion Rate under Section 6.04(b) or Section 6.04(c) will 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 Section 6.04(b) or Section 6.04(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 Section 6.04(b) or Section 6.04(c) was made, (1) in the case of any such rights or warrants which shall all have been redeemed or purchased without exercise by any Holders thereof, the Conversion Rate shall be readjusted upon such final purchase 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 purchase price received by a holder of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all applicable holders of Common Stock as of the date of such redemption or purchase, 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.

Section 6.13. Company Determination Final. Any determination that the Company or its Board of Directors must make pursuant to this Article 6 shall be conclusive if made in good faith and in accordance with the provisions of this Article 6, absent manifest error, and set forth in a Board Resolution.

Section 6.14. Limitation on Conversion Rate Adjustments. Notwithstanding anything to the contrary in this Indenture, certain listing standards of The New York Stock Exchange may limit the amount by which the Company may increase the Conversion Rate pursuant to clauses (b) through (e) of Section 6.04 and Section 6.06. These standards generally require the Company to obtain the approval of its stockholders before entering into certain transactions that could potentially result in the issuance of 20% or more of the Common Stock outstanding at the time the Securities are issued unless the Company obtains stockholder approval of issuances in excess of such limitations. In accordance with these listing standards, these restrictions will apply at any time when the Securities are outstanding, regardless of whether the Company then has a class of securities listed on The New York Stock Exchange. Accordingly, in the event of an increase in the Conversion Rate that would result in the Securities, in the aggregate, becoming convertible into shares of Common Stock in excess of such limitations, the Company will, at its option, either obtain stockholder approval of such transactions leading to an increase in the Conversion Rate or deliver cash in lieu of any shares otherwise deliverable upon conversions in excess of such limitations (based on the Last Reported Sale Price of the Common Stock on the Trading Day immediately prior to the date when such shares would otherwise be required to be distributed).

ARTICLE 7

EVENTS OF DEFAULT; REMEDIES

Section 7.01. Events of Default. “Event of Default,” wherever used herein, means any one of the following events:

(a) default in the payment of interest, including any Additional Interest, on any Security when due and payable and the default continues for a period of 30 days;

(b) default in the payment of the Principal Amount of any Security when due and payable at Stated Maturity, upon required repurchase upon a Fundamental Change, upon declaration or otherwise;

(g) default by the Company or any Subsidiary with respect to any mortgage, agreement or other instrument which results in the acceleration of maturity, in each case of any indebtedness for money borrowed in excess of $40 million in the aggregate of the Company and/or any such Subsidiary, whether such indebtedness now exists or is hereafter created (i) resulting in such

indebtedness becoming or being declared due and payable or (ii) constituting a failure to pay the principal or interest of any such debt when due and payable at its stated maturity, upon required repurchase, upon declaration or otherwise;

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

(i) the commencement by the Company or by a Significant Subsidiary of 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 or of a Significant Subsidiary 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 a Significant Subsidiary 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 or by a Significant Subsidiary of the Company in furtherance of any such action; or

(j) a final judgment for the payment of $40 million or more (excluding any amounts covered by insurance) rendered against the Company or any Significant Subsidiary, which judgment is not discharged or stayed within 60 days after (i) the date on which the right to appeal thereof has expired if no such appeal has commenced, or (ii) the date on which all rights to appeal have been extinguished.

The Trustee shall not be charged with knowledge of any Event of Default unless written notice thereof shall have been given to a Responsible Officer at the Corporate Trust Office of the Trustee by the Company, a Paying Agent, any Holder or any agent of any Holder.

Section 7.02. Acceleration of Maturity; Rescission and Annulment.

(a) If an Event of Default (other than those specified in Section 7.01(h) and 7.01(i)) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate Principal Amount of the Outstanding Securities may (and the Trustee upon request of such Holders shall) declare the Principal Amount plus accrued and unpaid interest, including Additional 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, including Additional Interest, shall become immediately due and payable.

Notwithstanding the foregoing, in the case of an Event of Default specified in Section 7.01(h) or Section 7.01(i)), the Principal Amount plus accrued and unpaid interest, including Additional Interest, on all Outstanding Securities will ipso facto become due and payable immediately without any declaration or other act on the part of the Trustee or any Holder.

Notwithstanding the foregoing, to the extent elected by the Company as provided in this Section 7.02(a), the sole remedy for an Event of Default relating to the failure of the Company to file any documents or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act and for any failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act or of the covenants made in Sections 4.04 and 4.06, 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 equal to 0.25% of the Principal Amount of the Securities. Such Additional Interest shall be in addition to any Additional Interest that may accrue as a result of a default under the Registration Rights Agreement. If the Company so elects, such Additional Interest will be payable on all Outstanding Securities from and including the date on which such Event of Default first occurs to but not including the 90th day thereafter (or such earlier date on which the Event of Default relating to the Company’s reporting obligations shall have been cured or waived). On the 90th day after such Event of Default (or earlier, if the Event of Default relating to the reporting obligations is not cured or waived prior to such 90th day), such Additional Interest shall cease to accrue and, if such Event of Default has not been cured or waived prior to such 90th day, the Securities will be subject to acceleration as provided above. The provisions of this paragraph shall not affect the rights of Holders of Securities in the event of the occurrence of any

other Event of Default. If the Company does not elect to pay the Additional Interest upon an Event of Default in accordance with this paragraph, the Securities will be subject to acceleration as provided above.

In order to elect to pay the Additional Interest as the sole remedy during the first 90 days after the occurrence of an Event of Default relating to the Company’s failure to comply with its reporting obligations in accordance with the immediately preceding paragraph, the Company must notify all Holders of Securities and the Trustee and Paying Agent of such election in writing within ten Business Days of making such election. Upon the Company’s failure to give such notice or pay the Additional Interest, the Securities will be immediately subject to acceleration as provided above.

(b) At any time after such a declaration of acceleration has been made, the Holders of a majority in aggregate Principal Amount of the Outstanding Securities, by written notice to the Company and the Trustee, may waive all past Defaults and rescind and annul such declaration with respect to the Securities and its consequences (other than with respect to an Event of Default under Sections 7.01(a) or 7.01(b)) if:

(i) such rescission and annulment will not conflict with any judgment or decree of a court of competent jurisdiction; and

(ii) all Events of Default, other than the non-payment of the Principal Amount plus accrued and unpaid interest, including Additional interest, on Securities that have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 7.12.

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

Section 7.03. 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, including Additional Interest, at the Maturity thereof or in the payment of the Fundamental Change Purchase 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 amounts required pursuant to Section 7.07.

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

If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy to collect the payment of the Principal Amount plus accrued but unpaid interest, including Additional 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 7.04. 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 10.07.

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; provided, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ committee or other similar committee.

Section 7.05. Application of Money and Property Collected. Any money and property 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 or property 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 10.07;

SECOND: To the payment of the amounts then due and unpaid on the Securities for the Principal Amount, Fundamental Change Purchase Price or interest, including Additional 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 payment of the remainder, if any, to the Company or any other Person lawfully entitled thereto.

Section 7.06. 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 the Securities, 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 Section 7.01(a) or Section 7.01(b)), 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 pursue such remedy in its own name as Trustee hereunder;

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

(iv) the Trustee for 60 days after its receipt of such notice, request and provision 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 7.07. 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, Fundamental Change Purchase Price or accrued and unpaid interest in respect of the Securities held by such Holder, on or after the respective due dates expressed in the Securities or any Fundamental Change Purchase Date, as applicable, and to convert the Securities in accordance with Article 6, 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 7.08. 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 7.09. 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 3.07, 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 7.10. 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 7.11. 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;

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

(iii) the Trustee may refuse to follow any such direction that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability.

Section 7.12. 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 Section 7.01(a) or Section 7.01(b); or

(ii) in respect of a covenant or provision hereof which under Article 13 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 7.13. 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 7.13 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 on any Security on or after Maturity of such Security or the Fundamental Change Purchase Price.

Section 7.14. 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, extension or usury law or other law which would prohibit

or forgive the Company from paying all or any portion of the principal of or interest, including Additional Interest, if any, on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or 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.

Section 7.15. Notice of Default. The Trustee may withhold notice to the Holders of the Securities of any Event of Default, except defaults in payment of Principal Amount or interest, including Additional Interest, if any, on the Securities, if and so long as a committee of the Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interest of the Holders of the Securities.

ARTICLE 8

CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE

Section 8.01. Company May Consolidate, Only on Certain Terms. The Company shall not consolidate with or merge with or into, or convey, transfer or lease all or substantially all of its properties and assets to, any Person, unless:

(a) the resulting, surviving or transferee Person, if not the Company (the “Successor Company”), is a Person organized and existing under the laws of the United States of America, any state thereof or the District of Columbia, and the Successor Company (if not the Company itself) expressly assumes, by a supplemental indenture, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all of the obligations of the Company under the Securities, this Indenture and, to the extent then still operative, the Registration Rights Agreement;

(b) immediately after giving effect to such transaction, no Event of Default shall have occurred and be continuing; and

(c) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, comply with this Article and that all conditions precedent herein provided for relating to such transaction have been complied with, and the Trustee, subject to Section 6.01, may rely upon such Officers’ Certificate and Opinion of Counsel as conclusive evidence that such transaction complies with this Section 8.01.

Section 8.02. Successor Substituted. Upon any consolidation of the Company with, or merger of the Company with or into, any other Person or any conveyance, transfer or lease of the properties and assets of the Company substantially as an entirety in accordance with Section 8.01, the Successor Company formed by such consolidation or into which the Company is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein, and thereafter.

ARTICLE 9

SUBORDINATION OF THE SECURITIES

Section 9.01. Agreement of Subordination. The Company covenants and agrees, and each Holder of Securities issued hereunder by its acceptance thereof likewise covenants and agrees, that all Securities shall be issued subject to the provisions of this Article 9; and each Person holding any Security, whether upon original issue or upon transfer, assignment or exchange thereof, accepts and agrees to be bound by such provisions.

The payment of the principal of, and the cash portion of the conversion obligation as set forth in Article 6, and any interest (including Additional Interest) on, and any of the Company’s other cash payment obligation with respect to all Securities (including, but not limited to, the Fundamental Change Purchase Price with respect to the Securities subject to purchase in accordance with Article 5 as provided in this Indenture) issued hereunder shall, to the extent and in the manner hereinafter set forth, be subordinated and subject in right of payment to the prior payment in full, in cash or other payment satisfactory to the holders of Senior Indebtedness, of all Senior Indebtedness, whether outstanding at the date of this Indenture or thereafter incurred.

No provision of this Article 9 shall prevent the occurrence of any default or Event of Default hereunder.

Section 9.02. Payments to Holders. No payment shall be made with respect to the principal of, or premium on, if any, the cash portion of the conversion obligation, if any, or interest on, the Securities (including, but not limited to, the Fundamental Change Purchase Price with respect to the Securities subject to purchase in accordance with Article 5 as provided in this Indenture), except payments and distributions made by the Trustee as permitted by the first or second paragraph of Section 9.05, if:

(i) a default in the payment of principal, premium, interest, rent or other obligations due on any Designated Senior Indebtedness

occurs and is continuing (or, in the case of Designated Senior Indebtedness for which there is a period of grace, in the event of such a default that continues beyond the period of grace, if any, specified in the instrument or lease evidencing such Designated Senior Indebtedness), unless and until such default shall have been cured or waived or shall have ceased to exist; or

(ii) a default, other than a payment default, under any Designated Senior Indebtedness occurs and is continuing that then permits holders of such Designated Senior Indebtedness to accelerate its maturity and the Trustee receives a written notice of the default (a “Payment Blockage Notice”) from a Representative or holder of such Designated Senior Indebtedness, unless and until the earlier of (x) the date on which such default is cured or waived or ceases to exist or (y) 179 days after the date on which the Payment Blockage Notice is received.

If the Trustee receives any Payment Blockage Notice pursuant to clause (ii) above, no subsequent Payment Blockage Notice shall be effective for purposes of this Section unless and until at least 365 days shall have elapsed since the initial effectiveness of the immediately prior Payment Blockage Notice and all scheduled payments on the Securities that have come due have been paid in full in cash. No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee (unless such default was waived for a period of 90 days, cured or otherwise ceased to exist and thereafter subsequently reoccurred) shall be, or be made, the basis for a subsequent Payment Blockage Notice.

The Company may and shall resume payments on and distributions in respect of the Securities upon the earlier of:

(a) in the case of a default referred to in clause (i) above, the date upon which the default is cured or waived or ceases to exist, or

(b) in the case of a default referred to in clause (ii) above, the earlier of the date on which such default is cured or waived or ceases to exist or 179 days after the date on which the applicable Payment Blockage Notice is received, if the maturity of such Designated Senior Indebtedness has not been accelerated, unless this Article 9 otherwise prohibits the payment or distribution at the time of such payment or distribution.

Upon any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon any dissolution or winding-up or liquidation or reorganization of the Company (whether voluntary or involuntary) or in bankruptcy, insolvency, receivership or similar proceedings, all amounts due or to become due upon all

Senior Indebtedness shall first be paid in full, in cash or other payment satisfactory to the holders of Senior Indebtedness, before any payment is made on account of the principal of, and premium, if any, the cash portion of the conversion obligation, if any, or interest on, the Securities (except payments made pursuant to Article 12 from monies deposited with the Trustee pursuant thereto prior to commencement of proceedings for such dissolution, winding-up, liquidation or reorganization); and upon any such dissolution or winding-up or liquidation or reorganization of the Company or bankruptcy, insolvency, receivership or other proceeding, any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the Holders of the Securities or the Trustee would be entitled, except for the provision of this Article 9, shall (except as aforesaid) be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the Holders of the Securities or by the Trustee under this Indenture, if received by them or it, directly to the holders of Senior Indebtedness (pro rata to such holders on the basis of the respective amounts of Senior Indebtedness held by such holders, or as otherwise required by law or a court order) or their Representative or Representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay all Senior Indebtedness in full, in cash or other payment satisfactory to the holders of Senior Indebtedness, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness, before any payment or distribution is made to the Holders of the Securities or to the Trustee.

For purposes of this Article 9, the words, “cash, property or securities” shall not be deemed to include shares of stock of the Company, as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this Article 9 with respect to the Securities to the payment of all Senior Indebtedness which may at the time be outstanding; provided that (i) the Senior Indebtedness is assumed by the new corporation, if any, resulting from any reorganization or readjustment and (ii) the rights of the holders of Senior Indebtedness (other than leases which are not assumed by the Company or the new corporation, as the case may be) are not, without the consent of such holders, altered by such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance, transfer or lease of its property as an entirety, or substantially as an entirety, to another corporation upon the terms and conditions provided for in Article 8 shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section 9.02 if such other corporation shall, as a part of such consolidation, merger, conveyance, transfer or lease, comply with the conditions stated in Article 8.

In the event of the acceleration of the Securities because of an Event of Default, no payment or distribution shall be made to the Trustee or any Holder of Securities in respect of the principal of, and premium, if any, the cash portion of the conversion obligation, if any, or interest on, the Securities by the Company (including, but not limited to, the Fundamental Change Purchase Price with respect to the Securities subject to purchase in accordance with Article 5 as provided in this Indenture), until all Senior Indebtedness has been paid in full in cash or other payment satisfactory to the holders of Senior Indebtedness or such acceleration is rescinded in accordance with the terms of this Indenture. If payment of Securities is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Indebtedness of such acceleration.

In the event that, notwithstanding the foregoing provisions, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities (including, without limitation, by way of setoff or otherwise), prohibited by the foregoing, shall be received by the Trustee or the Holders of the Securities before all Senior Indebtedness is paid in full, in cash or other payment satisfactory to the holders of Senior Indebtedness, or provision is made for such payment thereof in accordance with its terms in cash or other payment satisfactory to the holders of Senior Indebtedness, such payment or distribution shall be held in trust for the benefit of and shall be paid over or delivered to the holders of Senior Indebtedness or their Representative or Representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, as calculated by the Company, for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all Senior Indebtedness in full, in cash or other payment satisfactory to the holders of Senior Indebtedness, after giving effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness.

Section 9.03. Subrogation of Securities. Subject to the payment in full, in cash or other payment satisfactory to the holders of Senior Indebtedness, of all Senior Indebtedness, the rights of the Holders of the Securities shall be subrogated to the extent of the payments or distributions made to the holders of such Senior Indebtedness pursuant to the provisions of this Article 9 (equally and ratably with the holders of all indebtedness of the Company which by its express terms is subordinated to other indebtedness of the Company to substantially the same extent as the Securities are subordinated and is entitled to like rights of subrogation) to the rights of the holders of Senior Indebtedness to receive payments or distributions of cash, property or securities of the Company applicable to the Senior Indebtedness until the principal of, and premium, if any,

the cash portion of the conversion obligation, if any, and interest on, the Securities shall be paid in full, in cash or other payment satisfactory to the holders of Senior Indebtedness; and, for the purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any cash, property or securities to which the Holders of the Securities or the Trustee would be entitled except for the provisions of this Article 9, and no payment over, pursuant to the provisions of this Article 9, to or for the benefit of the holders of Senior Indebtedness by Holders of the Securities or the Trustee shall, as between the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Securities, be deemed to be a payment by the Company to or on account of the Senior Indebtedness; and no payments or distributions of cash, property or securities to or for the benefit of the Holders of the Securities pursuant to the subrogation provisions of this Article 9, which would otherwise have been paid to the holders of Senior Indebtedness, shall be deemed to be a payment by the Company to or for the account of the Securities. It is understood that the provisions of this Article 9 are and are intended solely for the purposes of defining the relative rights of the Holders of the Securities, on the one hand, and the holders of the Senior Indebtedness, on the other hand.

Nothing contained in this Article 9 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors other than the holders of Senior Indebtedness and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Securities the principal of, and premium, if any, the cash portion of the conversion obligation, if any, and any interest on the Securities as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders of the Securities and creditors of the Company other than the holders of the Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article 9 of the holders of Senior Indebtedness in respect of cash, property or securities of the Company received upon the exercise of any such remedy.

Upon any payment or distribution of assets of the Company referred to in this Article 9, the Trustee and the Holders of the Securities shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which such bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, delivered to the Trustee or to the Holders of the Securities, for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon and all other facts pertinent thereto or to this Article 9.

Section 9.04. Authorization to Effect Subordination. Each Holder of a Security by the Holder’s acceptance thereof authorizes and directs the Trustee on the Holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article 9 and appoints the Trustee to act as the Holder’s attorney-in-fact for any and all such purposes.

Section 9.05. Notice to Trustee. The Company shall give prompt written notice in the form of an Officers’ Certificate to a Responsible Officer of the Trustee and to any Paying Agent of any fact known to the Company which would prohibit the making of any payment of monies to or by the Trustee or any Paying Agent in respect of the Securities pursuant to the provisions of this Article 9. Notwithstanding the provisions of this Article 9 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment of monies to or by the Trustee in respect of the Securities pursuant to the provisions of this Article 9, unless and until a Responsible Officer of the Trustee shall have received written notice thereof at the Corporate Trust Office from the Company (in the form of an Officers’ Certificate) or a Representative or a holder or holders of Senior Indebtedness or from any trustee thereof; and before the receipt of any such written notice, the Trustee shall be entitled in all respects to assume that no such facts exist; provided that, if on a date not less than one Business Day prior to the date upon which by the terms hereof any such monies may become payable for any purpose (including, without limitation, the payment of the principal of, or premium, if any, or interest on, any Security) the Trustee shall not have received, with respect to such monies, the notice provided for in this Section 9.05, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such monies and to apply the same to the purpose for which they were received and shall not be affected by any notice to the contrary which may be received by it on or after such prior date. Notwithstanding anything in this Article 9 to the contrary, nothing shall prevent any payment by the Trustee to the Holders of monies deposited with it pursuant to Article 12, and any such payment shall not be subject to the provisions of Article 9.

The Trustee shall be entitled to rely on the delivery to it of a written notice by a Representative or a person representing himself to be a holder of Senior Indebtedness (or a trustee on behalf of such holder) to establish that such notice has been given by a Representative or a holder of Senior Indebtedness or a trustee on behalf of any such holder or holders. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article 9, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent

to the rights of such Person under this Article 9, and if such evidence is not furnished the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment.

Section 9.06. Trustee’s Relation to Senior Indebtedness. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article 9 in respect of any Senior Indebtedness at any time held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder.

With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article 9, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness, and, except with respect to its express obligations under this Article 9, the Trustee shall not be liable to any holder of Senior Indebtedness if it shall pay over or deliver to Holders of Securities, the Company or any other person money or assets to which any holder of Senior Indebtedness shall be entitled by virtue of this Article 9 or otherwise.

Section 9.07. No Impairment of Subordination. No right of any present or future holder of any Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder or by any noncompliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or otherwise be charged with.

Section 9.08. Certain Conversions Deemed Payment. For the purposes of this Article 9 only, (1) the issuance and delivery of junior securities upon conversion of Securities in accordance with Article 6 shall not be deemed to constitute a payment or distribution on account of the principal of, or premium, if any, the cash portion of the conversion obligation, if any, or interest on, Securities or on account of the purchase or other acquisition of Securities, and (2) the payment, issuance or delivery of cash (except in satisfaction of fractional shares pursuant to Article 6), property or securities (other than junior securities) upon conversion of a Security shall be deemed to constitute payment on account of the principal of such Security. For the purposes of this Section 9.08, the term “junior securities” means (a) shares of any stock of any class of the Company or (b) securities of the Company which are subordinated in right of payment to all Senior Indebtedness which may be outstanding at the time of issuance or delivery of such securities to substantially the same extent as, or to a greater extent than, the Securities are so subordinated as provided in this Article. Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or

shall impair, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders, the right, which is absolute and unconditional, of the Holder of any Security to convert such Security in accordance with Article 6.

Section 9.09. Article Applicable to Paying Agents. If at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article shall (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article in addition to or in place of the Trustee; provided that the first paragraph of Section 9.05 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent.

Section 9.10. Senior Indebtedness Entitled to Rely. The holders of Senior Indebtedness (including, without limitation, Designated Senior Indebtedness) shall have the right to rely upon this Article 9, and no amendment or modification of the provisions contained herein shall diminish the rights of such holders unless such holders shall have agreed in writing thereto.

Section 9.11. Anti-Layering. The Company shall not incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is subordinate or junior in right of payment to any Senior Indebtedness, unless such Indebtedness ranks equal or junior in right of payment to the Securities. For purposes of the foregoing, for the avoidance of doubt, no Indebtedness shall be deemed to be subordinated in right of payment to any other Indebtedness solely by virtue of being unsecured or secured by a junior priority lien or by virtue of the fact that the holders of such Indebtedness have entered into intercreditor agreements or other arrangements giving one or more of such holders priority over the other holders in the collateral held by them or by virtue of structural subordination.

Section 9.12. All Indenture Provisions Subject to Article 9. Notwithstanding anything herein contained herein to the contrary, all the provisions of this Indenture shall be subject to the provisions of this Article 9, so far as the same may be applicable thereto. Nothing in this Article 9 shall apply to claims of, or payments to the Trustee under or pursuant to Section 10.07.

ARTICLE 10

THE TRUSTEE

Section 10.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default which may have occurred, undertakes to perform such duties and only

such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs.

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

(a) prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have occurred:

(i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture and the Trust Indenture Act, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture and the Trust Indenture Act against the Trustee; and

(ii) in the absence of bad faith and willful misconduct on the part of the Trustee, the Trustee may conclusively rely as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein);

(b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless the Trustee was negligent in ascertaining the pertinent facts;

(c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the written direction of the Holders of not less than a majority in Principal Amount of the Securities at the time outstanding determined as provided in Section 1.04 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture;

(d) whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section;

(e) the Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Company or any other paying agent or any records maintained by any co-registrar with respect to the Securities; and

(f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to the Trustee, the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred.

None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

Section 10.02. Notice of Defaults. If a Default occurs and is continuing of which the Trustee has or is deemed to have notice under Section 10.03(i), the Trustee shall give the Holders notice of the Default within 90 days after the occurrence thereof; provided that (except in the case of any Default in the payment of Principal Amount or Interest on any of the Securities or Fundamental Change Purchase Price), the Trustee shall be protected in withholding such notice if and so long as a committee of Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interest of the Holders of Securities.

Section 10.03. Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section 10.01:

(a) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, note, coupon or other paper or document (whether in its original or facsimile form) believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties;

(b) any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an Officers’ Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company;

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

(d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Securityholders pursuant to the provisions of this Indenture, unless such Securityholders shall have provided to the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby;

(e) 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 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 reasonable expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation);

(f) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed by it with due care hereunder;

(g) the Trustee shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture;

(h) 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;

(i) the Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and the Indenture;

(j) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder; and

(k) the Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specific actions pursuant to this Indenture.

Section 10.04. No Responsibility for Recitals, Etc. The recitals contained herein and in the Securities (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities. The Trustee shall not be accountable for the use or application by the Company of any Securities or the proceeds of any Securities authenticated and delivered by the Trustee in conformity with the provisions of this Indenture.

Section 10.05. Trustee, Paying Agents, Conversion Agents or Registrar May Own Securities. The Trustee, any paying agent, any authenticating agent, any conversion agent or Security Registrar, in its individual or any other capacity, may become the owner or pledgee of Securities with the same rights it would have if it were not Trustee, paying agent, conversion agent or Security Registrar.

Section 10.06. Monies to be Held in Trust. Subject to the provisions of Section 12.04, all monies and properties received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. 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 may be agreed in writing from time to time by the Company and the Trustee.

Section 10.07. Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to from time to time in writing between the Company and the Trustee, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence or willful misconduct. The Company

also covenants and agrees to indemnify the Trustee (or any officer, director or employee of the Trustee), in any capacity under this Indenture and its agents and any authenticating agent for, and to hold them harmless against, any and all loss, liability, claim, damage or expense incurred without negligence or willful misconduct on the part of the Trustee or such officers, directors, employees and agent or authenticating agent, as the case may be, and arising out of or in connection with the acceptance or administration of this trust or in any other capacity hereunder, including the costs and expenses of defending themselves against any claim of liability in the premises. The obligations of the Company under this Section 10.07 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a lien prior to that of the Securities upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Securities. The obligation of the Company under this Section shall survive the satisfaction and discharge of this Indenture.

When the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 7.01(h) or (i) with respect to the Company occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency or similar laws.

Section 10.08. Officers’ Certificate as Evidence. Except as otherwise provided in Section 10.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or willful misconduct on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee.

Section 10.09. Conflicting Interests of Trustee. 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 10.10. Eligibility of Trustee. 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 a combined capital and surplus of at least $50,000,000 (or if such Person is a member of a bank holding company system, its bank holding company shall have 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 any supervising or examining authority, then for the purposes of this Section 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 10.10, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 10.11. Resignation or Removal of Trustee.

(a) The Trustee may at any time resign by giving written notice of such resignation to the Company and to the Holders of Securities. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have accepted appointment 60 days after the mailing of such notice of resignation to the Securityholders, the resigning Trustee may, upon ten business days’ notice to the Company and the Securityholders, appoint a successor identified in such notice or may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee, or, any Securityholder who has been a bona fide Holder of a Security or Securities for at least 6 months may, subject to the provisions of Section 7.13, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

(b) In case at any time any of the following shall occur:

(i) the Trustee shall fail to comply with Section 10.09 after written request therefor by the Company or by any Securityholder who has been a bona fide Holder of a Security or Securities for at least 6 months; or

(ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 10.10 and shall fail to resign after written request therefor by the Company or by any such Securityholder; or

(iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or 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, the Company may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the

provisions of Section 7.13, any Securityholder who has been a bona fide Holder of a Security or Securities for at least 6 months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee; provided that if no successor Trustee shall have been appointed and have accepted appointment 60 days after either the Company or the Securityholders has removed the Trustee, the Trustee so removed may petition at its own expense any court of competent jurisdiction for an appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

(c) The Holders of a majority in aggregate Principal Amount of the Securities at the time outstanding may at any time remove the Trustee and nominate a successor trustee which shall be deemed appointed as successor trustee unless, within ten days after notice to the Company of such nomination, the Company objects thereto, in which case the Trustee so removed or any Securityholder, or if such Trustee so removed or any Securityholder fails to act, the Company, upon the terms and conditions and otherwise as in Section 10.11(a) provided, may petition any court of competent jurisdiction for an appointment of a successor trustee.

Any successor trustee appointed as provided in Section 10.11 shall upon payment of any fees and expenses due and owing the predecessor trustee hereunder, execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amount then due it pursuant to the provisions of Section 10.07, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a lien upon all property and funds held or collected by such trustee as such, except for funds held in trust for the benefit of Holders of particular Securities, to secure any amounts then due it pursuant to the provisions of Section 10.07.

No successor trustee shall accept appointment as provided in this Section 10.12 unless, at the time of such acceptance, such successor trustee shall be qualified under the provisions of Section 10.09 and be eligible under the provisions of Section 10.10.

Upon acceptance of appointment by a successor trustee as provided in this Section 10.12, the Company (or the former trustee, at the written direction of the Company) shall mail or cause to be mailed notice of the succession of such trustee hereunder to the Holders of Securities at their addresses as they shall appear on the Security Register. If the Company fails to mail such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company.

Section 10.13. Succession by ▇▇▇▇▇▇. 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 of the corporate trust business of the Trustee (including any trust created by this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that in the case of any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, such corporation shall be qualified under the provisions of Section 10.09 and eligible under the provisions of Section 10.10.

In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee or any authenticating agent appointed by such successor trustee may authenticate such Securities in the name of the successor trustee; and in all such cases such certificates shall have the full force that is provided in the Securities or in this Indenture; provided that the right to adopt the certificate of authentication of any predecessor Trustee or authenticate Securities in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

Section 10.14. Preferential Collection of Claims. 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 the claims against the Company (or any such other obligor).
