The Notes shall be signed in the name and on behalf of the Company by the manual or facsimile signature of one of its Chairman of the Board, Chief Executive Officer, Chief Financial Officer, President or any Vice President (whether or not designated by a number or numbers or word or words added before or after the title “Vice President”) and attested by the manual or facsimile signature of its Secretary or any of its Assistant Secretaries or its Treasurer or any of its Assistant Treasurers (which may be printed, engraved or otherwise reproduced thereon, by facsimile or otherwise). Only such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the form of Note attached as Exhibit A hereto, manually executed by the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 19.11), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of this Indenture.

In case any officer of the Company who shall have signed any of the Notes shall cease to be such officer before the Notes so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such officer of the Company, and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the proper officers of the Company, although at the date of the execution of this Indenture any such person was not such an officer.

SECTION 2.05. Exchange and Registration of Transfer of Notes; Restrictions on Transfer. (a) The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office and in any other office or agency of the Company designated pursuant to Section 5.02 being herein sometimes collectively referred to as the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. The Note Register shall be in written form or in any form capable of being converted into written form within a reasonably prompt period of time. The Trustee is hereby appointed “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or more co-registrars in accordance with Section 5.02.

Upon surrender for registration of transfer of any Note to the Note Registrar or any co-registrar, and satisfaction of the requirements for such transfer set forth in this

Section 2.05, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture.

Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency maintained by the Company pursuant to Section 5.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes which the Noteholder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding.

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

All Notes presented or surrendered for registration of transfer or for exchange, redemption, repurchase or conversion shall (if so required by the Company or the Note Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company, and the Notes shall be duly executed by the Noteholder thereof or his attorney duly authorized in writing.

No service charge shall be made to any holder for any registration of, transfer or exchange of Notes, but the Company may require payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes.

Neither the Company nor the Trustee nor any Note Registrar shall be required to exchange or register a transfer of (a) any Notes for a period of fifteen (15) days next preceding any selection of Notes to be redeemed, (b) any Notes or portions thereof called for redemption pursuant to Section 3.02, (c) any Notes or portions thereof surrendered for conversion pursuant to Article 15, (d) any Notes or portions thereof tendered for repurchase (and not withdrawn) pursuant to Section 3.05 or (e) any Notes or portions thereof tendered for repurchase (and not withdrawn) pursuant to Section 3.06.

(b) The following provisions shall apply only to Global Notes:

(i) Each Global Note authenticated under this Indenture shall be registered in the name of the Depositary or a nominee thereof and delivered to such Depositary or a nominee thereof or Custodian therefor, and each such Global Note shall constitute a single Note for all purposes of this Indenture.

(ii) Notwithstanding any other provision in this Indenture, no Global Note may be exchanged in whole or in part for Notes registered, and no transfer of a Global Note in whole or in part may be registered, in the name of any Person other than the Depositary or a nominee thereof unless (A) the Depositary (i) has notified the Company that it is unwilling or unable to continue as Depositary for

such Global Note and a successor depositary has not been appointed by the Company within ninety days or (ii) has ceased to be a clearing agency registered under the Exchange Act and a successor depositary has not been appointed by the Company within ninety days, (B) an Event of Default has occurred and the maturity of the Notes shall have been accelerated in accordance with Section 7.01 and any Noteholder shall have given written notice to the Company requesting the issuance of definitive Notes or (C) the Company, in its sole discretion, notifies the Trustee in writing that it no longer wishes to have all the Notes represented by Global Notes. Any Global Note exchanged pursuant to clause (A) or (B) above shall be so exchanged in whole and not in part and any Global Note exchanged pursuant to clause (C) above may be exchanged in whole or from time to time in part as directed by the Company. Any Note issued in exchange for a Global Note or any portion thereof shall be a Global Note; provided that any such Note so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Note.

(iii) Securities issued in exchange for a Global Note or any portion thereof pursuant to clause (ii) above shall be issued in definitive, fully registered form, without coupons, shall have an aggregate principal amount equal to that of such Global Note or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear any legends required hereunder. Any Global Note to be exchanged in whole shall be surrendered by the Depositary to the Note Registrar. With regard to any Global Note to be exchanged in part, either such Global Note shall be so surrendered for exchange or, if the Trustee is acting as Custodian for the Depositary or its nominee with respect to such Global Note, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and make available for delivery the Note issuable on such exchange to or upon the written order of the Depositary or an authorized representative thereof.

(iv) In the event of the occurrence of any of the events specified in clause (ii) above, the Company will promptly make available to the Trustee a reasonable supply of certificated Notes in definitive, fully registered form, without coupons.

(v) Neither any members of, or participants in, the Depositary (“Agent Members”) nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Note registered in the name of the Depositary or any nominee thereof, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on

whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Note.

(vi) At such time as all interests in a Global Note have been redeemed, repurchased, converted, canceled or exchanged for Notes in certificated form, such Global Note shall, upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is redeemed, repurchased, converted, canceled or exchanged for Notes in certificated form, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction.

(c) Every Note that bears or is required under this Section 2.05(c) to bear the legend set forth in this Section 2.05(c) (together with any Common Stock issued upon conversion of the Notes and required to bear the legend set forth in Section 2.05(d), collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including those set forth in the legend below) unless such restrictions on transfer shall be waived by written consent of the Company, and the holder of each such Restricted Security, by such holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 2.05(c), the term “transfer” encompasses any sale, pledge, loan, transfer or other disposition whatsoever of any Restricted Security or any interest therein.

Until the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof, which shall bear the legend set forth in Section 2.05(d)) shall bear a legend in substantially the following form, unless such Note has been sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer) or pursuant to Rule 144 under the Securities Act or any similar provision then in force, or unless otherwise agreed by the Company in writing, with written notice thereof to the Trustee:

THIS SECURITY AND THE COMMON STOCK (“COMMON STOCK”) OF ON SEMICONDUCTOR CORPORATION (THE “COMPANY”) ISSUABLE UPON CONVERSION OF THIS SECURITY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. NEITHER THIS SECURITY, THE COMMON STOCK ISSUABLE UPON CONVERSION OF THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN OR THEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION.

THE HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE HEREOF, AGREES TO OFFER, SELL OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE DATE (THE “RESALE RESTRICTION TERMINATION DATE”) THAT IS TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF AND THE LAST DATE ON WHICH THE COMPANY OR ANY AFFILIATE OF THE COMPANY WAS THE OWNER OF THIS SECURITY (OR ANY PREDECESSOR OF SUCH SECURITY) ONLY (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHICH NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (C) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, OR (D) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE RIGHTS OF THE COMPANY AND THE WITHIN MENTIONED TRUSTEE PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (D) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM, AND IN EACH OF THE FOREGOING CASES WHERE REGISTRATION OR TRANSFER OF THIS SECURITY IS REQUIRED, A CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THE OTHER SIDE OF THIS SECURITY COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE TRUSTEE. THIS LEGEND WILL BE REMOVED AFTER THE RESALE RESTRICTION TERMINATION DATE UPON REQUEST OF THE HOLDER AND THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATES AND/OR OTHER INFORMATION SATISFACTORY TO THE COMPANY.

Any Note (or security issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired in accordance with their terms or as to conditions for removal of the foregoing legend set forth therein have been satisfied may, upon surrender of such Note for exchange to the Note Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.05(c). If the Restricted Security surrendered for exchange is represented by a Global Note bearing the legend set forth in this Section 2.05(c), the principal amount of the legended Global Note shall be reduced by the appropriate principal amount and the principal amount of a Global Note without the legend set forth in this Section 2.05(c) shall be increased by an equal principal amount. If a Global Note without the legend set forth in this Section 2.05(c) is not then outstanding, the Company shall execute and the Trustee shall authenticate and deliver an unlegended Global Note to the Depositary.

(d) Until the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), any stock certificate representing Common Stock issued upon conversion of any Note shall bear

a legend in substantially the following form, unless such Common Stock has been sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer) or pursuant to Rule 144 under the Securities Act or any similar provision then in force, or such Common Stock has been issued upon conversion of Notes that have been transferred pursuant to a registration statement that has been declared effective under the Securities Act or pursuant to Rule 144 under the Securities Act or any similar provision then in force, or unless otherwise agreed by the Company in writing with written notice thereof to the transfer agent:

THE COMMON STOCK (“COMMON STOCK”) OF ON SEMICONDUCTOR CORPORATION (THE “COMPANY”) EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. NEITHER THIS COMMON STOCK NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION.

THE HOLDER OF THIS COMMON STOCK, BY ITS ACCEPTANCE HEREOF, AGREES TO OFFER, SELL OR OTHERWISE TRANSFER SUCH COMMON STOCK PRIOR TO THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THE COMMON STOCK EVIDENCED HEREBY UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION) ONLY (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHICH NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (C) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, OR (D) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE RIGHTS OF THE COMPANY AND THE WITHIN MENTIONED TRUSTEE PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (D) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM, AND IN EACH OF THE FOREGOING CASES WHERE REGISTRATION OR TRANSFER OF THIS SECURITY IS REQUIRED, A CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THE OTHER SIDE OF THIS SECURITY COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE TRUSTEE. THIS LEGEND WILL BE REMOVED AFTER THE RESALE RESTRICTION TERMINATION DATE UPON REQUEST OF THE HOLDER AND THE DELIVERY OF AN OPINION OF

COUNSEL, CERTIFICATES AND/OR OTHER INFORMATION SATISFACTORY TO THE COMPANY.

(e) Any Note or Common Stock issued upon the conversion of a Note that, prior to the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), is purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction which results in such Notes or Common Stock, as the case may be, no longer being Restricted Securities (as defined under Rule 144).

(f) The Trustee shall have no responsibility or obligation to any Agent Members or any other Person with respect to the accuracy of the books or records, or the acts or omissions, of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any Agent Member or other Person (other than the Depositary) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Noteholder and all payments to be made to Noteholders under the Notes shall be given or made only to or upon the order of the registered Noteholders (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to the customary procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its Agent Members.

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

SECTION 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and make available for delivery, a new Note, bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen, if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Noteholder (a) satisfies the Company within a reasonable time after he has notice of such loss, destruction or wrongful taking and the Note Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Company or the Trustee prior to the Note being acquired by a protected purchaser as defined in

Section 8-303 of the Uniform Commercial Code and (c) satisfies any other reasonable requirements of the Trustee. In every case, the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

Following receipt by the Trustee or such authenticating agent, as the case may be, of satisfactory security or indemnity and evidence, as described in the preceding paragraph, the Trustee or such authenticating agent may authenticate any such substituted Note and make available for delivery such Note. Upon the issuance of any substituted Note, the Company may require the payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note which has matured or is about to mature or has been called for redemption or has been tendered for repurchase upon a Designated Event (and not withdrawn) or has been surrendered for repurchase on a Repurchase Date (and not withdrawn) or is to be converted into Common Stock shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or in connection with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, the Trustee and, if applicable, any paying agent or conversion agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion or redemption or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion or redemption or repurchase of negotiable instruments or other securities without their surrender.

SECTION 2.07. Temporary Notes. Pending the preparation of Notes in certificated form, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon the written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in

any authorized denomination, and substantially in the form of the Notes in certificated form, but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Notes in certificated form. Without unreasonable delay, the Company will execute and deliver to the Trustee or such authenticating agent Notes in certificated form and thereupon any or all temporary Notes may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 5.02 and the Trustee or such authenticating agent shall authenticate and make available for delivery in exchange for such temporary Notes an equal aggregate principal amount of Notes in certificated form. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Notes in certificated form authenticated and delivered hereunder.

SECTION 2.08. Cancellation of Notes. All Notes surrendered for the purpose of payment, redemption, repurchase, conversion, exchange or registration of transfer shall, if surrendered to the Company or any paying agent or any Note Registrar or any conversion agent, be surrendered to the Trustee and promptly canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by it, and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of such canceled Notes in accordance with its customary procedures. If the Company shall acquire any of the Notes, such acquisition shall not operate as a redemption, repurchase or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation.

SECTION 2.09. CUSIP Numbers. The Company in issuing the Notes may use CUSIP numbers (if then generally in use), and, if so, the Trustee shall use CUSIP numbers in notices of redemption or repurchases as a convenience to Noteholders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption or a repurchase and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption or repurchase shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the CUSIP numbers.

ARTICLE 3

REDEMPTION AND REPURCHASE OF NOTES

SECTION 3.01. Redemption of Notes. The Company may not redeem any Notes prior to December 20, 2013. At any time on or after December 20, 2013 and prior to maturity, the Notes may be redeemed at the option of the Company, in whole or in part, upon notice as set forth in Section 3.02, at a cash redemption price equal to 100% of the principal amount plus accrued and unpaid interest including Additional Interest, if any, to, but excluding, the redemption date (the “Redemption Price”); provided, however,

that if the redemption date falls after a Regular Record Date and on or prior to the corresponding Interest Payment Date, then interest payable on such Interest Payment Date shall be paid on such Interest Payment Date to the holders of record of such Notes on the applicable Regular Record Date instead of the holders surrendering such Notes for redemption and the Redemption Price payable will be 100% of the principal amount of such Notes and will not include any interest.

SECTION 3.02. Notice of Optional Redemption; Selection of Notes. In case the Company shall desire to exercise the right to redeem all or, as the case may be, any part of the Notes pursuant to Section 3.01, it shall fix a date for redemption and it or, at its written request received by the Trustee not fewer than forty-five (45) days prior (or such shorter period of time as may be acceptable to the Trustee) to the date fixed for redemption, the Trustee in the name of and at the expense of the Company, shall mail or cause to be mailed a notice of such redemption not fewer than thirty (30) nor more than sixty (60) days prior to the redemption date to each holder of Notes so to be redeemed as a whole or in part at its last address as the same appears on the Note Register; provided that if the Company shall give such notice, it shall also give written notice of the redemption date to the Trustee. Such mailing shall be by first class mail. The notice, if mailed in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note.

Each such notice of redemption shall specify the aggregate principal amount of Notes to be redeemed, the CUSIP number or numbers of the Notes being redeemed, the date fixed for redemption (which shall be a Business Day), the Redemption Price at which Notes are to be redeemed, the place or places of payment, and that payment will be made upon presentation and surrender of such Notes. Such notice shall also state the current Conversion Rate, the date on which the right to convert such Notes or portions thereof will expire and whether the Company has elected to pay the Net Share Amount in cash pursuant to Section 15.02(c). If fewer than all the Notes are to be redeemed, the notice of redemption shall identify the Notes to be redeemed (including CUSIP numbers, if any). In case any Note is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that, on and after the redemption date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion thereof will be issued.

On or prior to the redemption date specified in the notice of redemption given as provided in this Section 3.02, the Company will deposit with the Trustee or with one or more paying agents (or, if the Company is acting as its own paying agent, set aside, segregate and hold in trust as provided in Section 5.04) an amount of money in immediately available funds sufficient to redeem on the redemption date all the Notes (or portions thereof) so called for redemption (other than those theretofore surrendered for conversion) at the appropriate Redemption Price; provided that if such payment is made on the redemption date it must be received by the Trustee or paying agent, as the case may be, by 10:00 a.m. New York City time on such date. The Company shall be entitled

to retain any interest, yield or earnings on amounts deposited with the Trustee or any paying agent pursuant to this Section 3.02 in excess of amounts required hereunder to pay the Redemption Price of all Notes to be redeemed on such date. If any Note called for redemption is converted pursuant hereto prior to such redemption date, any money deposited with the Trustee or any paying agent or so segregated and held in trust for the redemption of such Note shall be paid to the Company upon its written request, or, if then held by the Company, shall be discharged from such trust. Whenever any Notes are to be redeemed, the Company will give the Trustee written notice in the form of an Officers’ Certificate not fewer than forty-five (45) days (or such shorter period of time as may be acceptable to the Trustee) prior to the redemption date as to the aggregate principal amount of Notes to be redeemed.

If less than all of the outstanding Notes are to be redeemed, the Trustee shall select the Notes or portions thereof of the Global Note or the Notes in certificated form to be redeemed (in principal amounts of $1,000 or multiples thereof) by lot, on a pro rata basis or by another method the Trustee deems fair and appropriate. If any Note selected for partial redemption is submitted for conversion in part after such selection, the portion of such Note submitted for conversion shall be deemed (so far as may be possible) to be the portion to be selected for redemption. The Notes (or portions thereof) so selected shall be deemed duly selected for redemption for all purposes hereof, notwithstanding that any such Note is submitted for conversion in part before the mailing of the notice of redemption.

Upon any redemption of less than all of the outstanding Notes, the Company and the Trustee may (but need not), solely for purposes of determining the pro rata allocation among such Notes as are unconverted and outstanding at the time of redemption, treat as outstanding any Notes surrendered for conversion during the period of fifteen (15) days next preceding the mailing of a notice of redemption and may (but need not) treat as outstanding any Note authenticated and delivered during such period in exchange for the unconverted portion of any Note converted in part during such period.

SECTION 3.03. Payment of Notes Called for Redemption by the Company. If notice of redemption has been given as provided in Section 3.02, the Notes or portion of Notes with respect to which such notice has been given shall, unless converted pursuant to the terms hereof, become due and payable on the date fixed for redemption and at the place or places stated in such notice at the applicable Redemption Price, after the close of business on the Business Day immediately preceding the redemption date (unless the Company shall default in the payment of such Notes at the Redemption Price) interest shall cease to accrue on such Notes and such Notes shall cease to be convertible and, except as provided in Section 8.05 and Section 13.04, to be entitled to any benefit or security under this Indenture, and the holders thereof shall have no right in respect of such Notes except the right to receive the Redemption Price thereof. On presentation and surrender of such Notes at a place of payment in said notice specified, the said Notes or the specified portions thereof shall be paid and redeemed by the Company at the applicable Redemption Price.

Upon presentation of any Note redeemed in part only, the Company shall execute and the Trustee shall authenticate and make available for delivery to the holder thereof, at the expense of the Company, a new Note or Notes, of authorized denominations, in principal amount equal to the unredeemed portion of the Notes so presented.

If any Note called for redemption shall not be so paid upon surrender thereof for redemption, such Note shall remain convertible until the principal shall have been paid or duly provided for.

SECTION 3.04. Conversion Arrangement on Call for Redemption. In connection with any redemption of Notes, the Company may arrange for the purchase and conversion of any Notes by an agreement with one or more investment banks or other purchasers to purchase such Notes by paying to the Trustee in trust for the Noteholders, on or before the date fixed for redemption, an amount not less than the applicable Redemption Price of such Notes. Notwithstanding anything to the contrary contained in this Article 3, the obligation of the Company to pay the Redemption Price of such Notes shall be deemed to be satisfied and discharged to the extent such amount is so paid by such purchasers. If such an agreement is entered into, a copy of which will be filed with the Trustee prior to the date fixed for redemption, any Notes not duly surrendered for conversion by the holders thereof may, at the option of the Company, be deemed, to the fullest extent permitted by law, acquired by such purchasers from such holders and (notwithstanding anything to the contrary contained in Article 15) surrendered by such purchasers for conversion, all as of immediately prior to the close of business on the date fixed for redemption (and the right to convert any such Notes shall be extended through such time), subject to payment of the above amount as aforesaid. At the direction of the Company, the Trustee shall hold and dispose of any such amount paid to it in the same manner as it would monies deposited with it by the Company for the redemption of Notes. Without the Trustee’s prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any Notes shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Trustee as set forth in this Indenture.

SECTION 3.05. Repurchase at Option of Noteholders Upon a Designated Event. (a) If there shall occur a Designated Event at any time prior to maturity of the Notes, then each Noteholder shall have the right, at such holder’s option, to require the Company to repurchase all of such holder’s Notes, or any portion thereof that is a multiple of $1,000 principal amount, on the date (the “Designated Event Repurchase Date”) specified by the Company that is thirty (30) days after the date of the Designated Event Notice (as defined in Section 3.05(b)) of such Designated Event at a cash repurchase price equal to 100% of the principal amount, plus accrued and unpaid interest, including Additional Interest, if any, to, but excluding, the Designated Event Repurchase Date (the “Designated Event Repurchase Price”); provided, however, that if the Designated Event Repurchase Date falls after a Regular Record Date and on or prior to the corresponding Interest Payment Date, then interest payable on such Interest Payment Date shall be paid on such Interest Payment Date to the holders of record of such Notes on the applicable Regular Record Date instead of the holders surrendering such Notes for repurchase and the Designated Event Repurchase Price payable will be 100% of the

principal amount of such Note and will not include any interest. Repurchases of Notes under this Section 3.05 shall be made, at the option of the holder thereof, upon:

(i) delivery to the Trustee (or other paying agent appointed by the Company) by a holder of a duly completed notice (the “Designated Event Repurchase Notice”) in the form set forth on the reverse of the Note on or before the close of business on the second Business Day immediately preceding the Designated Event Repurchase Date; and

(ii) delivery or book-entry transfer of the Notes to the Trustee (or other paying agent appointed by the Company) at any time after delivery of the Designated Event Repurchase Notice (together with all necessary endorsements) at the Corporate Trust Office of the Trustee (or other paying agent appointed by the Company) in the Borough of Manhattan as provided in Section 5.02, such delivery being a condition to receipt by the holder of the Designated Event Repurchase Price therefor; provided that such Designated Event Repurchase Price shall be so paid pursuant to this Section 3.05 only if the Note so delivered to the Trustee (or other paying agent appointed by the Company) shall conform in all respects to the description thereof in the related Designated Event Repurchase Notice.

The Company shall purchase from the holder thereof, pursuant to this Section 3.05, a portion of a Note, if the principal amount of such portion is $1,000 or a whole multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a Note also apply to the purchase of such portion of such Note.

Any purchase by the Company contemplated pursuant to the provisions of this Section 3.05 shall be consummated by the delivery of the consideration to be received by the holder promptly following the later of the Designated Event Repurchase Date and the time of the book-entry transfer or delivery of the Note.

Notwithstanding anything herein to the contrary, any holder delivering to the Trustee (or other paying agent appointed by the Company) the Designated Event Repurchase Notice contemplated by this Section 3.05 shall have the right to withdraw such Designated Event Repurchase Notice at any time prior to the close of business on the Designated Event Repurchase Date by delivery of a written notice of withdrawal to the Trustee (or other paying agent appointed by the Company) in accordance with Section 3.05(c) below.

The Trustee (or other paying agent appointed by the Company) shall promptly notify the Company of the receipt by it of any Designated Event Repurchase Notice or written notice of withdrawal thereof.

(b) On or before the 30th day after the occurrence of a Designated Event, the Company or at its written request (which must be received by the Trustee at least five (5) Business Days prior to the date the Trustee is requested to give notice as described below, unless the Trustee shall agree in writing to a shorter period), the Trustee, in the

name of and at the expense of the Company, shall mail or cause to be mailed to all holders of record on the date of the Designated Event a notice (the “Designated Event Notice”) prepared by the Company of the occurrence of such Designated Event and of the repurchase right at the option of the holders arising as a result thereof. Such notice shall be mailed in the manner and with the effect set forth in the first paragraph of Section 3.02 (without regard for the time limits set forth therein). If the Company shall give such notice, the Company shall also deliver a copy of the Designated Event Notice to the Trustee at such time as it is mailed to Noteholders.

Each Designated Event Notice shall specify the circumstances constituting the Designated Event, the Designated Event Repurchase Date, the price at which the Company shall be obligated to repurchase Notes, that the holder must exercise the repurchase right on or prior to the close of business on the Designated Event Repurchase Date (the “Designated Event Expiration Time”), that the holder shall have the right to withdraw any Notes surrendered prior to the Designated Event Expiration Time, a description of the procedure which a Noteholder must follow to exercise such repurchase right and to withdraw any surrendered Notes, the place or places where the holder is to surrender such holder’s Notes, whether, in respect of any Notes converted prior to the Designated Event Repurchase Date, the Company has elected to pay the Net Share Amount in cash pursuant to Section 15.02(c) and the CUSIP number or numbers of the Notes (if then generally in use) and include a form of Designated Event Repurchase Notice.

No failure of the Company to give the foregoing notices and no defect therein shall limit the Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 3.05.

(c) A Designated Event Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the office of the Trustee (or other paying agent appointed by the Company) in accordance with the Designated Event Repurchase Notice at any time prior to the close of business on the Designated Event Repurchase Date, specifying:

(i) the certificate number, if any, of the Note in respect of which such notice of withdrawal is being submitted, or the appropriate Depositary information if the Note in respect of which such notice of withdrawal is being submitted is represented by a Global Note,

(ii) the principal amount of the Note with respect to which such notice of withdrawal is being submitted, and

(iii) the principal amount, if any, of such Note which remains subject to the original Designated Event Repurchase Notice and which has been or will be delivered for purchase by the Company.

(d) On or prior to the Designated Event Repurchase Date, the Company will deposit with the Trustee (or other paying agent appointed by the Company or if the

Company is acting as its own paying agent, set aside, segregate and hold in trust as provided in Section 5.04) an amount of money sufficient to repurchase on the Designated Event Repurchase Date all the Notes to be repurchased on such date at the appropriate Designated Event Repurchase Price; provided that if such payment is made on the Designated Event Repurchase Date it must be received by the Trustee or paying agent, as the case may be, by 10:00 a.m. New York City time, on such date. Subject to receipt of funds and/or Notes by the Trustee (or other paying agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn) prior to the Designated Event Expiration Time will be made promptly (but in no event more than five (5) Business Days) following the later of (x) the Designated Event Repurchase Date with respect to such Note (provided the holder has satisfied the conditions in this Section 3.05) and (y) the time of delivery of such Note to the Trustee (or other paying agent appointed by the Company) by the holder thereof in the manner required by this Section 3.05) by mailing checks for the amount payable to the holders of such Notes entitled thereto as they shall appear in the Note Register.

If the Trustee (or other paying agent appointed by the Company) holds money sufficient to repurchase on the Designated Event Repurchase Date all the Notes or portions thereof that are to be purchased as of the Designated Event Repurchase Date, then on or after the Designated Event Repurchase Date (i) the Notes will cease to be outstanding, and interest, including Additional Interest, if any, will cease to accrue on the Notes, and (ii) all other rights of the holders of such Notes will terminate, whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or paying agent, other than the right to receive the Designated Event Repurchase Price upon delivery of the Notes.

(e) In the case of a reclassification, change, consolidation, merger, combination, sale or conveyance to which Section 15.06 applies, in which the Common Stock of the Company is changed or exchanged as a result into the right to receive stock, securities or other property or assets (including cash), which includes shares of Common Stock of the Company or shares of common stock of another Person that are, or upon issuance will be, traded on a United States national securities exchange or approved for trading on an established automated over-the-counter trading market in the United States and such shares constitute at the time such change or exchange becomes effective in excess of 50% of the aggregate Fair Market Value of such stock, securities or other property or assets (including cash), then the Person formed by such consolidation or resulting from such merger or which acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture (accompanied by an Opinion of Counsel that such supplemental indenture complies with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) modifying the provisions of this Indenture relating to the right of holders of the Notes to cause the Company to repurchase the Notes following a Designated Event, including without limitation the applicable provisions of this Section 3.05 and the definitions of Common Stock and Designated Event, as appropriate, as determined in good faith by the Company (which determination shall be conclusive and binding), to make such provisions apply to such other Person if

different from the Company and the common stock issued by such Person (in lieu of the Company and the Common Stock of the Company).

(f) To the extent required by applicable law, the Company will comply with the provisions of Rule 13e-4 and any other tender offer rules under the Exchange Act in connection with the repurchase rights of the holders of Notes in the event of a Designated Event.

Unless the Company has elected to redeem all of the Notes in accordance with Section 3.01, Notes shall be purchased by the Company pursuant to the terms of the Notes at the option of the holder on December 15 of 2013, 2016 and 2021 (each, a “Repurchase Date”), for cash, at a repurchase price of 100% of the principal amount plus accrued and unpaid interest including additional interest, if any, to, but excluding, the Repurchase Date (the “Repurchase Price”); provided, however, that if the Repurchase Date falls after a Regular Record Date and on or prior to the corresponding Interest Payment Date, then interest payable on such Interest Payment Date shall be paid on such Interest Payment Date to the holders of record of such Notes on the applicable Regular Record Date instead of the holders surrendering such Notes for repurchase and the Repurchase Price payable will be 100% of the principal amount of such Note and will not include any interest; provided further, however, that no Notes may be repurchased by the Company pursuant to this Section 3.06 if the principal amount of the Notes has been accelerated and such acceleration has not been rescinded on or prior to the Repurchase Date. Repurchases of Notes under this Section 3.06 shall be made, at the option of the holder thereof, upon:

(a) delivery to the Trustee (or other paying agent appointed by the Company) by a holder of a duly completed notice (the “Repurchase Notice”) in the form set forth on the reverse of the Note during the period beginning at any time from the opening of business on the date that is 20 Business Days prior to the Repurchase Date until the close of business on the second Business Day immediately preceding the Repurchase Date; and

Notes in respect of which a Repurchase Notice has been given by the holder thereof may not be converted pursuant to Article 15 hereof on or after the date of the delivery of such Repurchase Notice unless such Repurchase Notice has first been validly withdrawn.

REMEDIES OF THE TRUSTEE AND NOTEHOLDERS

ON AN EVENT OF DEFAULT

SECTION 7.01. Events of Default. In case one or more of the following Events of Default (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body) shall have occurred and be continuing:

(a) default in any payment of interest, including any Additional Interest, on any Note when due and payable and such default continues for a period of 30 days, whether or not such payment shall be prohibited by Article 16; or

(b) default in the payment of the principal of any of the Notes as and when the same shall become due and payable either at maturity or in connection with any redemption, repurchase or otherwise, in each case pursuant to Article 3 whether or not such payment, redemption or purchase shall be prohibited by Article 16; or

(c) default in the Company’s obligation to provide a Designated Event Notice upon a Designated Event as provided in Section 3.05 within the time period specified in Section 3.05(b); or

(f) failure on the part of the Company or any Note Guarantor to comply with any of its agreements in the Notes or this Indenture (other than those referred to in (a), (b), (c) or (d) above) and such failure continues for 60 days after the notice specified below; or

(g) the failure by the Company to deliver the consideration payable under Article 15 upon conversion of the Notes within the time period specified in Section 15.02 and 15.10, and such failure continues for a period of 5 days after the notice specified below; or

(h) Indebtedness of the Company or any Restricted Subsidiary is not paid within any applicable grace period after final maturity or the acceleration by the holders thereof because of a default and the total amount of such Indebtedness unpaid or accelerated exceeds $25 million or its foreign currency equivalent at the time and such failure continues for 10 days after the notice specified below; or

(i) the Company or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

(1) commences a voluntary case;

(2) consents to the entry of an order for relief against it in an involuntary case;

(3) consents to the appointment of a Custodian of it or for any substantial part of its property; or

(4) makes a general assignment for the benefit of its creditors; or takes any comparable action under any foreign law relating to insolvency; or

(j) A court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(1) is for relief against the Company or any Significant Subsidiary in an involuntary case;

(2) appoints a Custodian of the Company or any Significant Subsidiary or for any substantial part of its property;

(3) orders the winding up or liquidation of the Company or any Significant Subsidiary; or

(k) with respect to any judgment or decree for the payment of money in excess of $25 million or its foreign currency equivalent against the Company or any Restricted Subsidiary (i) an enforcement proceeding is commenced thereon by any creditor if such judgment or decree is final and nonappealable and the Company or such Restricted Subsidiary, as applicable, fails to stay such proceeding within 10 days thereafter or (ii) the Company or such Restricted Subsidiary, as applicable, fails to pay such judgment or decree, which judgment or decree has remained outstanding for a period of 60 days following the entry of such judgment or decree without being paid, discharged, waived or stayed; or

(l) any Note Guarantee of any Significant Subsidiary ceases to be in full force and effect (except as contemplated by the terms thereof) or any Significant Subsidiary that is a Note Guarantor or Person acting by or on behalf of such Significant Subsidiary denies or disaffirms such Significant Subsidiary’s obligations under this Indenture or any Note Guarantee and such Default continues for 10 days after receipt of the notice specified in this Indenture;

then, and in each and every such case (other than an Event of Default specified in Section 7.01(i) or 7.01(j)), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the holders of not less than twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding hereunder determined in accordance with Section 9.04, by notice in writing to the Company (and to the Trustee if given by Noteholders), may declare 100% of the principal and accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Notes contained to the contrary notwithstanding. If an Event of Default specified in Section 7.01(i) or 7.01(j) or occurs, the principal of and accrued and unpaid interest and accrued and unpaid Additional Interest, if any, all the Notes shall be immediately and automatically due and payable without necessity of further action. This provision, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the

payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest and accrued and unpaid Additional Interest, if any, upon all Notes and the principal (with interest on all such amounts that are overdue at the rate of 1.00% per annum above the otherwise applicable interest rate on the Notes) and amounts due to the Trustee pursuant to Section 8.06, and if any and all defaults under this Indenture, other than the nonpayment of principal and accrued and unpaid interest and accrued and unpaid Additional Interest, if any, of which shall have become due by acceleration, shall have been cured or waived pursuant to Section 7.07, then and in every such case the holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default and rescind and annul such declaration and its consequences; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. A Default under (d), (f), (g), (h) or (l) above is not an Event of Default until the Trustee notifies the Company or the Noteholders of at least 25% in principal amount of the outstanding Notes notify the Company and the Trustee of the Default and the Company or the relevant Note Guarantor, as applicable, do not cure such Default within the time specified after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default”. The Company shall notify in writing a Responsible Officer of the Trustee, promptly upon becoming aware thereof, of any Event of Default. The Company shall deliver to the Trustee, within 30 days after the occurrence thereof, written notice in the form of an Officers’ Certificate of any event which with the giving of notice or the lapse of time would become an Event of Default under clauses (d), (e), (f), (h), (k) or (l), its status and what action the Issuers are taking or propose to take with respect thereto.

Notwithstanding the foregoing provisions, to the extent elected by the Company, the sole remedy of holders of the Notes for an Event of Default relating to the failure 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 Section 6.04 of this Indenture, will for the first 220 days after the occurrence of such an Event of Default consist exclusively of the right to receive an extension fee on the Notes in an amount equal to 1.00% of the principal amount of the Notes. If the Company so elects, the extension fee will be payable on all outstanding Notes on the date on which an Event of Default relating to a failure to comply with the reporting obligations referred to in the immediately preceding sentence first occurs, which will be the 60th day after a Notice of Default is provided to the Company by the Trustee or the holders of at least 25% in principal amount of the Notes of its failure to so comply. On the 220th day after such Event of Default (if such Event of Default is not cured or waived prior to such 220th day), the Notes will be subject to acceleration as provided above. The provisions of this paragraph will not affect the rights of holders of Notes in the event of the occurrence of any other Event of Default. In the event the Company does not elect to pay the extension fee upon an Event of Default in accordance with the provisions of this paragraph, the Notes will be due and payable on the 60th day after the relevant Notice of Default.

In order to elect to pay the extension fee as the sole remedy during the first 220 days after the occurrence of an Event of Default relating to the failure to comply with the reporting obligations referred to in the immediately preceding paragraph, the Company must notify all holders of Notes and the Trustee and paying agent of such election and the aggregate amount of such extension fee on or before the close of business on the date on which such Event of Default occurs, which will be the 60th day after notice to the Company of its failure to so comply.

Notwithstanding the provisions of Section 15.05(n), the failure by the Company to adjust the Conversion Rate pursuant to the terms of Section 15.05 shall constitute an Event of Default pursuant to the terms of this Section 7.01.

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of such waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the holders of Notes, and the Trustee shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the holders of Notes, and the Trustee shall continue as though no such proceeding had been taken.

SECTION 7.02. Payments of Notes on Default; Suit Therefor. The Company and each Note Guarantor covenants that in case default shall be made in the payment of the principal of, or accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on, any of the Notes as and when the same shall have become due and payable, whether at maturity of the Notes or in connection with any redemption or repurchase, by or under this Indenture declaration or otherwise, then, upon demand of the Trustee, the Company or such Note Guarantor, is applicable, will pay to the Trustee, for the benefit of the holders of the Notes, the whole amount that then shall have become due and payable on all such Notes for principal, accrued and unpaid interest and accrued and unpaid Additional Interest, if any, with interest upon the overdue amounts at the rate of 1.00% per annum above the otherwise applicable interest rate on the Notes from the required payment date and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other amounts due the Trustee under Section 8.06. Until such demand by the Trustee, the Company may pay the principal of, and interest and Additional Interest, if any, on, the Notes to the registered holders, whether or not the Notes are overdue.

In case the Company or any Note Guarantor shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Company, any Note Guarantor or any other obligor on the Notes and collect in the manner provided by law out of the property of the Company, any Note Guarantor or any other obligor on the Notes wherever situated the monies adjudged or decreed to be payable.

In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company, any Note Guarantor or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company, such Note Guarantor or such other obligor, the property of the Company, such Note Guarantor or such other obligor, or in the case of any other judicial proceedings relative to the Company, such Note Guarantor or such other obligor upon the Notes, or to the creditors or property of the Company, such Note Guarantor or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 7.02, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and interest owing and unpaid in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and of the Noteholders allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due the Trustee under Section 8.06, and to take any other action with respect to such claims, including participating as a member of any official committee of creditors, as it reasonably deems necessary or advisable, and, unless prohibited by law or applicable regulations, and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Noteholders 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 Noteholders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including counsel fees and expenses incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property which the holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the holders of the Notes.

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the

Trustee shall be held to represent all the holders of the Notes, and it shall not be necessary to make any holders of the Notes parties to any such proceedings.

SECTION 7.03. Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 7 shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon 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 8.06;

SECOND: To holders of Senior Indebtedness of the Company to the extent required by Article 16 and the holders of Senior Indebtedness of the Note Guarantors to the extent required by Article 18;

THIRD: In case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount (including, if applicable, payments in respect of the Conversion Obligation and Additional Shares) then owing and unpaid upon the Notes for principal and premium, if any, and interest, including Additional Interest, if any, with interest on the overdue principal and premium, if any, and (to the extent that such interest has been collected by the Trustee) upon overdue payments of principal or interest, including Additional Interest and any interest payable pursuant to Section 5.01 at the rate of 1.00% per annum above the otherwise applicable interest rate on the Notes, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal and premium, if any, and interest without preference or priority of principal and premium, if any, over interest, or of interest over principal and premium, if any, or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal and premium, if any, and accrued and unpaid interest; and

FOURTH: To the payment of the remainder, if any, to the Company.

SECTION 7.04. Proceedings by Noteholder. No holder of any Note shall have any right by virtue of or by reference to any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, and unless also the holders of not less than twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable security or indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for sixty (60) days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding and no direction inconsistent with such written request

shall have been given to the Trustee pursuant to Section 7.07; it being understood and intended, and being expressly covenanted by the taker and holder of every Note with every other taker and holder and the Trustee, that no one or more holders of Notes shall have any right in any manner whatever by virtue of or by reference to any provision of this Indenture to affect, disturb or prejudice the rights of any other holder of Notes, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all holders of Notes (except as otherwise provided herein). For the protection and enforcement of this Section 7.04 each and every Noteholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Notwithstanding any other provision of this Indenture and any provision of any Note, the right of any holder of any Note to receive payment of the principal of, and accrued and unpaid interest, including Additional interest, if any, on, such Note (including the Redemption Price upon redemption pursuant to Article 3), on or after the respective due dates expressed in such Note or in the event of redemption, or to institute suit for the enforcement of any such payment on or after such respective dates against the Company shall not be impaired or affected without the consent of such holder.

Anything in this Indenture or the Notes to the contrary notwithstanding, the holder of any Note, without the consent of either the Trustee or the holder of any other Note, on its own behalf and for its own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, its rights of conversion as provided herein.

SECTION 7.05. Proceedings by Trustee. In case of an Event of Default, the Trustee may, in its discretion, proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

SECTION 7.06. Remedies Cumulative and Continuing. Except as provided in Section 2.06, all powers and remedies given by this Article 7 to the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or any acquiescence therein, and, subject to the provisions of Section 7.04, every power and remedy given by this Article 7 or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders.

SECTION 7.07. Direction of Proceedings and ▇▇▇▇▇▇ of Defaults by Majority of Noteholders. The holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 9.04 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 (a) such direction shall not be in conflict with any rule of law or with this Indenture, (b) the Trustee may take any other action which is not inconsistent with such direction, (c) the Trustee may decline to take any action that would benefit some Noteholder to the detriment of other Noteholders and (d) the Trustee may decline to take any action that would involve the Trustee in personal liability. The holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 9.04 may, on behalf of the holders of all of the Notes, waive any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of interest or Additional Interest, if any, on, or the principal of, the Notes when due which has not been cured pursuant to the provisions of Section 7.01, (ii) a default in the payment of the Redemption Price pursuant to Article 3, (iii) a default in the payment of the Designated Event Repurchase Price or Repurchase Price pursuant to Article 3 or (iv) a default in respect of a covenant or provisions hereof which under Article 11 cannot be modified or amended without the consent of the holders of each or all Notes then outstanding or affected thereby. Upon any such waiver, the Company, the Trustee and the holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 7.07, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

SECTION 7.08. Notice of Defaults. The Trustee shall, within the earlier of thirty (30) days after a Responsible Officer of the Trustee has actual knowledge of the occurrence of a default or ninety (90) days after it occurs, mail to all Noteholders, as the names and addresses of such holders appear upon the Note Register, notice of all defaults known to a Responsible Officer, unless such defaults shall have been cured or waived before the giving of such notice; provided that except in the case of default in the payment of the principal interest or Additional Interest, if any, on, any of the Notes, the Trustee shall be protected in withholding such notice if and so long as a trust committee of directors and/or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Noteholders.

SECTION 7.09. Undertaking to Pay Costs. All parties to this Indenture agree, and each holder of any Note by his acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such

party litigant; provided that the provisions of this Section 7.09 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 9.04, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of or interest, if any, on any Note on or after the due date expressed in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article 15.

ARTICLE 8

THE TRUSTEE

SECTION 8.01. 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, duties 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 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 Notes at the time outstanding determined as provided in Section 9.04 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;

(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; and

(g) the Trustee shall not be deemed to have knowledge of any Event of Default hereunder unless it shall have been notified in writing of such Event of Default by the Company or the holders of at least 10% in aggregate principal amount of the Notes.

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 8.02. Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section 8.01:

(a) the Trustee may conclusively rely and shall be protected in 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;

(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;

(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 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 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;

SECTION 8.03. No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (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 Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or the proceeds of any Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture.

SECTION 8.04. Trustee, Paying Agents, Conversion Agents or Note Registrar May Own Notes. The Trustee, any paying agent, any conversion agent or Note Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not Trustee, paying agent, conversion agent or Note Registrar.

SECTION 8.05. Monies to be Held in Trust. Subject to the provisions of Section 13.04, all monies 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 8.06. 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, such 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 shall be determined to have been caused by its own negligence or willful misconduct. The Company and each of the Note Guarantors, jointly and severally, covenants to indemnify the Trustee and any predecessor 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, damage, claim or expense including taxes (other than taxes based on the income of the Trustee) 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 (whether asserted by the Company, a Note Guarantor, any holder or any other Person) of liability in the premises. The obligations of the Company and the Note Guarantors under this Section 8.06 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 Notes 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 Notes. The obligation of the Company and the Note Guarantors 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(i) or (j) 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 8.07. Officers’ Certificate as Evidence. Except as otherwise provided in Section 8.01, 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 bad faith 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 8.08. 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 (i) eliminate such interest within 90 days, (ii) apply to the Commission for permission to continue as trustee or (iii) resign, in each case to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture.

SECTION 8.09. 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 $150,000,000 (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 $150,000,000). 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 8.09, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

SECTION 8.10. 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 Notes. 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 sixty (60) days after the mailing of such notice of resignation to the Noteholders, the resigning Trustee may, upon ten (10) Business Days’ notice to the Company and the Noteholders, petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee, or, if any Noteholder who has been a bona fide holder of a Note or Notes for at least six (6) months may, subject to the provisions of Section 7.09, 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 8.08 after written request therefor by the Company or by any Noteholder who has been a bona fide holder of a Note or Notes for at least six (6) months; or

(ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 8.09 and shall fail to resign after written request therefor by the Company or by any such Noteholder; 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 7.09, any Noteholder who has been a bona fide holder of a Note or Notes for at least six (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 sixty (60) days after either the Company or the Noteholders has removed the Trustee, or the Trustee resigns, the Trustee so removed may petition, at the expense of the Company, 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 Notes 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 (10) days after notice to the Company of such nomination, the Company objects

thereto, in which case the Trustee so removed or any Noteholder, or if such Trustee so removed or any Noteholder fails to act, the Company, upon the terms and conditions and otherwise as in Section 8.10 provided, may petition any court of competent jurisdiction for an appointment of a successor trustee.

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 8.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 8.11.

(e) Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 8.06 shall continue for the benefit of the retiring Trustee.

SECTION 8.11. Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 8.10 shall 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 8.06, 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 Notes, to secure any amounts then due it pursuant to the provisions of Section 8.06.

No successor trustee shall accept appointment as provided in this Section 8.11 unless, at the time of such acceptance, such successor trustee shall be qualified under the provisions of Section 8.08 and be eligible under the provisions of Section 8.09.

Upon acceptance of appointment by a successor trustee as provided in this Section 8.11, 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 Notes at their addresses as they shall appear on the Note Register. If the Company fails to mail such notice within ten (10) 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 8.12. 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 8.08 and eligible under the provisions of Section 8.09.

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

SECTION 8.13. Preferential Collection of Claims. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Notes), 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).

SECTION 8.14. Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the holders of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three (3) Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

ARTICLE 9

THE NOTEHOLDERS

SECTION 9.01. Action by Noteholders. Whenever in this Indenture it is provided that the holders of a specified percentage in aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of

taking any such action, the holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in writing, or (b) by the record of the holders of Notes voting in favor thereof at any meeting of Noteholders duly called and held in accordance with the provisions of Article 10, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Noteholders. Whenever the Company or the Trustee solicits the taking of any action by the holders of the Notes, the Company or the Trustee may fix in advance of such solicitation, a date as the record date for determining holders entitled to take such action. The record date shall be not more than fifteen (15) days prior to the date of commencement of solicitation of such action.

SECTION 9.02. Proof of Execution by Noteholders. Subject to the provisions of Sections 8.01, 8.02 and 10.05, proof of the execution of any instrument by a Noteholder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the registry of such Notes or by a certificate of the Note Registrar.

The record of any Noteholders’ meeting shall be proved in the manner provided in Section 10.06.

SECTION 9.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any paying agent, any conversion agent and any Note Registrar may deem the Person in whose name such Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on account of the principal of and interest, if any, on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any paying agent nor any conversion agent nor any Note Registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being, or upon his order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any such Note.

SECTION 9.04. Company-Owned Notes Disregarded. In determining whether the holders of the requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes which are owned by the Company or any other obligor on the Notes or any Affiliate of the Company or any other obligor on the Notes shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action, only Notes which a Responsible Officer knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith may be regarded as outstanding for the purposes of this Section 9.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to vote such Notes and that the pledgee is

not the Company, any other obligor on the Notes or any Affiliate of the Company or any such other obligor. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above-described Persons, and, subject to Section 8.01, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination.

SECTION 9.05. Revocation of Consents, Future Noteholders Bound. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 9.01, of the taking of any action by the holders of the percentage in aggregate principal amount of the Notes specified in this Indenture in connection with such action, any holder of a Note which is shown by the evidence to be included in the Notes the holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 9.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the holder of any Note shall be conclusive and binding upon such holder and upon all future holders and owners of such Note and of any Notes issued in exchange or substitution therefor, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor.

SECTION 10.03. Call of Meetings by Company or Noteholders. In case at any time the Company, pursuant to a resolution of its Board of Directors, or the holders of at least twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding, shall have requested the Trustee to call a meeting of Noteholders, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have mailed the notice of such meeting within twenty (20) days after receipt of such request, then the Company or such Noteholders may determine the time and the place for such meeting and may call such meeting to take any action authorized in Section 10.01, by mailing notice thereof as provided in Section 10.02.

A permanent chairman and a permanent secretary of the meeting shall be

elected by vote of the holders of a majority in principal amount of the Notes represented at the meeting and entitled to vote at the meeting.

Subject to the provisions of Section 9.04, at any meeting each Noteholder or proxyholder shall be entitled to one vote for each $1,000 principal amount of Notes held or represented by him; provided that no vote shall be cast or counted at any meeting in respect of any Note challenged as not outstanding and ruled by the chairman of the meeting to be not outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Notes held by him or instruments in writing as aforesaid duly designating him as the proxy to vote on behalf of other Noteholders. Any meeting of Noteholders duly called pursuant to the provisions of Section 10.02 or 10.03 may be adjourned from time to time by the holders of a majority of the aggregate principal amount of Notes represented at the meeting, whether or not constituting a quorum, and the meeting may be held as so adjourned without further notice.

If the Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such amendment or supplemental indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 19.11) and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding.

SECTION 11.05. Evidence of Compliance of Amendment or Supplemental Indenture to Be Furnished to Trustee. Prior to entering into any amendment or supplemental indenture, the Trustee shall be provided with an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any amendment or supplemental indenture executed pursuant hereto complies with the requirements of this Article 11 and is otherwise authorized or permitted by this Indenture.

SECTION 11.06. Execution of Amendment or Supplemental Indenture for Future Note Guarantors. Each Subsidiary which is required to become a Note Guarantor pursuant to Section 5.08 shall promptly execute and deliver to the Trustee an amendment or supplemental indenture pursuant to which such Subsidiary shall become a Note Guarantor under this Section 11.06 and shall guarantee the Guaranteed Obligations. Concurrently with the execution and delivery of such amendment or supplemental indenture, the Company shall deliver to the Trustee an Opinion of Counsel and an Officers’ Certificate to the effect that such amendment or supplemental indenture has been duly authorized, executed and delivered by such Subsidiary and that, subject to the

application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Note Guarantee of such Note Guarantor is a legal, valid and binding obligation of such Note Guarantor, enforceable against such Note Guarantor in accordance with its terms and or to such other matters as the Trustee may reasonably request.

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

SECTION 12.01. When Company May Merge or Transfer Assets. (a) The Company shall not consolidate with or merge with or into, or convey, transfer or lease all or substantially all its assets to, any Person, unless:

(i) the resulting, surviving or transferee Person (the “Successor Company”) shall be a corporation 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 as the case may be) shall expressly assume, by a supplemental indenture hereto, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all the obligations of the Company under the Notes and this Indenture;

(ii) immediately after giving effect to such transaction (and treating any Indebtedness which becomes an obligation of the Successor Company or any Restricted Subsidiary as a result of such transaction as having been Incurred by the Successor Company or such Restricted Subsidiary at the time of such transaction), no Default shall have occurred and be continuing; and

The Successor Company shall succeed to, and be substituted for, and may exercise every right and power of the Company under this Indenture.

(b) The Company shall not permit any Note Guarantor to consolidate with or merge with or into, or convey, transfer or lease all or substantially all of its assets to any Person unless:

(i) in the case of any Note Guarantor which is a Domestic Subsidiary, the resulting, surviving or transferee Person will be a corporation, partnership or limited liability company organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and such Person (if not such Note Guarantor) shall expressly assume, by a supplemental indenture, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of such Note Guarantor under its Note Guarantee;

(ii) immediately after giving effect to such transaction (and treating any Indebtedness which becomes an obligation of the resulting, surviving or transferee Person as a result of such transaction as having been Incurred by such Person at the time of such transaction), no Default shall have occurred and be continuing; and

(iii) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with this Indenture; provided, however, that the foregoing shall not apply to any Note Guarantor which ceases to Guarantee any Indebtedness of the Company evidenced by any outstanding Designated Notes.

SECTION 12.02. Successor to Be Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or lease and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of, and accrued interest, including Additional Interest, if any, on, all of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company, such successor Person shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of this first part. Such successor Person thereupon may cause to be signed, and may issue either in its own name or in the name of ON Semiconductor Corporation any or all of the Notes, issuable hereunder that theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor Person instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the officers of the Company to the Trustee for authentication, and any Notes that such successor Person thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance, transfer or lease, the Person named as the “Company” in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 12 may be dissolved, wound up and liquidated at any time thereafter and such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture.

In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate.

SECTION 13.01. Discharge of Indenture. When (a) the Company shall deliver to the Trustee for cancellation all Notes theretofore authenticated (other than any Notes that have been destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) and not theretofore canceled, or (b) all the Notes not theretofore canceled or delivered to the Trustee for cancellation shall have become due and payable, or are by their terms to become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption, and the Company shall deposit with the Trustee, in trust, funds or U.S. Government Obligations sufficient to pay at maturity or upon redemption of all of the Notes (other than any Notes that shall have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) not theretofore canceled or delivered to the Trustee for cancellation, including principal and accrued interest, including Additional Interest, if any, due or to become due to such date of maturity or redemption date, as the case may be, accompanied by a verification report, in the case of a deposit of U.S. Government Obligations, as to the sufficiency of the deposited amount, from an independent certified accountant or other financial professional satisfactory to the Trustee, and if the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this Indenture shall cease to be of further effect (except as to (i) remaining rights of registration of transfer, substitution and exchange and conversion of Notes, (ii) rights hereunder of Noteholders to receive payments of principal of and interest, if any, on, the Notes and the other rights, duties and obligations of Noteholders, as beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee and (iii) the rights, obligations and immunities of the Trustee hereunder), and the Trustee, on written demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel as required by Section 19.05 and at the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture; the Company, however, hereby agrees to reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred by the Trustee and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this Indenture or the Notes.

SECTION 13.02. Deposited Monies to Be Held in Trust by Trustee. Subject to Section 13.04, all monies or securities deposited with the Trustee pursuant to Section 13.01, shall be held in trust for the sole benefit of the Noteholders, and such monies shall be applied by the Trustee to the payment, either directly or through any paying agent (including the Company if acting as its own paying agent), to the holders of the particular Notes for the payment or redemption of which such monies have been deposited with the Trustee, of all sums due and to become due thereon for principal.

SECTION 13.03. Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of this Indenture, all monies then held by any paying agent of the Notes (other than the Trustee) shall, upon written request of the Company, be repaid to it or

paid to the Trustee, and thereupon such paying agent shall be released from all further liability with respect to such monies.

SECTION 13.04. Return of Unclaimed Monies. Subject to the requirements of applicable law, any monies deposited with or paid to the Trustee for payment of the principal and accrued interest, including Additional Interest, if any, on Notes and not applied but remaining unclaimed by the holders of Notes for two years after the date upon which the principal and accrued interest, including Additional Interest, if any, of such Notes, as the case may be, shall have become due and payable, shall be repaid to the Company by the Trustee on demand and all liability of the Trustee shall thereupon cease with respect to such monies; and the holder of any of the Notes shall thereafter look only to the Company for any payment that such holder may be entitled to collect unless an applicable abandoned property law designates another Person.

SECTION 13.05. Reinstatement. If the Trustee or the paying agent is unable to apply any money in accordance with Section 13.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 13.01 until such time as the Trustee or the paying agent is permitted to apply all such money in accordance with Section 13.02; provided that if the Company makes any payment of principal and accrued interest, including Additional Interest, if any, of any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the holders of such Notes to receive such payment from the money held by the Trustee or paying agent.

ARTICLE 15

CONVERSION OF NOTES

SECTION 15.01. Right to Convert. (a) Subject to and upon compliance with the provisions of this Indenture, on or prior to December 14, 2026, the holder of any Note shall have the right, at such holder’s option, to convert the principal amount of the Note, or any portion of such principal amount which is a multiple of $1,000, at the Conversion Rate in effect at such time (the “Conversion Obligation”), by surrender of the Note so to be converted in whole or in part, together with any required funds, under the circumstances described in this Section 15.01 and in the manner provided in Section 15.02. Prior to June 15, 2013, the Notes shall be convertible only upon the occurrence of one of the following events:

(i) during the five Business Day period immediately following any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of the Notes for each day of such Measurement Period was less than 103% of the product of the Closing Sale Price and the applicable Conversion Rate on such Trading Day; or

(ii) as provided in Section 15.01(b).

On and after June 15, 2013, the Notes shall be convertible at any time.

Neither the conversion agent appointed by the Company nor the Trustee shall have an obligation to determine the Trading Price under this Section 15.01 unless the Company so requests by notice to the Trustee. The Company shall be obligated, within two Business Days, to make such a request notice if a holder of any Note so requests and either (i) such holder has provided the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than 103% of the product of the Closing Sale Price and the applicable Conversion Rate or (ii) such holder has agreed to reimburse the Company for the Trustee’s reasonable expenses in connection with the determination of the Trading Price of the Notes. For purposes of the preceding sentence, reasonable evidence shall consist of at least one bid by an Independent Nationally Recognized Securities Dealer, which bid shall have been made not more than two days prior to the holder’s request. Following a Company request notice, the Trustee shall determine the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 103% of the product of the Closing Sale Price and the applicable Conversion Rate, and the Company shall provide such Trading Price information to the holder that requested the determination of the Trading Price; provided that the Trustee shall be under no duty or obligation to make the calculations described in this Section 15.01(a) or to determine whether the Notes are convertible pursuant to such section. For the avoidance of doubt, the Company shall make the calculations described in this Section 15.01(a)(i), using the Trading Price provided by the Trustee. In connection with any request by a holder of any Note that the Trading Price of the Notes be determined, if the Trustee determines that the Trading Price per $1,000 principal amount of Notes was less than 103% of the product of the Closing

Sale Price and the Conversion Rate during each day of the applicable Measurement Period, the Company shall reimburse such holder for any amounts paid to the Company or the Trustee in connection with the making of such determination.

If the condition set forth in Section 15.01(a)(i) has been met, the Company shall so notify the holders of the Notes. Upon giving notice to the holders of the Notes that such Notes are convertible, so long as the Notes remain convertible, neither the Company nor the Trustee shall be obligated to measure the Trading Price per $1,000 principal amount of Notes until such time as the Company elects to instruct the Trustee to so measure. If at any point after the condition set forth in Section 15.01(a)(i) has been met, the Trading Price per $1,000 principal amount of Notes, as determined in accordance with this Section 15.01(a), is equal to or greater than 103% of the product of the Closing Sale Price and the applicable Conversion Rate, the Company shall so notify the holders of the Notes.

The Trustee shall be entitled at its sole discretion to consult with the Company and to request the assistance of the Company in connection with the Trustee’s duties and obligations pursuant to this Section 15.01(a) and the Company agrees, if requested by the Trustee, to cooperate with, and provide assistance to, the Trustee in carrying out its duties under this Section 15.01(a); provided that nothing herein shall be construed to relieve the Trustee of its duties pursuant to this Section 15.01(a).

(b) In addition, if prior to June 15, 2013:

(i) (A) the Company distributes to all holders of its Common Stock rights or warrants entitling them (for a period expiring within 45 days of the applicable record date for the determination of the stockholders entitled to receive such distribution) to subscribe for or purchase shares of Common Stock, at a price per share less than the average of the Closing Sale Price for the ten(10) Trading Days immediately preceding, but not including, the date such distribution is first publicly announced by the Company; or (B) the Company distributes to all holders of its Common Stock, cash or other assets, debt securities or rights to purchase its securities, where the Fair Market Value of such distribution per share of Common Stock exceeds 10% of the Closing Sale Price on the Trading Day immediately preceding the date such distribution is first publicly announced by the Company, then, in either case, the Notes may be surrendered for conversion at any time on and after the date that the Company gives notice to the holders of such distribution, which shall be not less than 20 days prior to the Ex-Dividend Time for such distribution, until the earlier of the close of business on the second Business Day immediately preceding, but not including, the Ex-Dividend Time or the date the Company publicly announces that such distribution will not take place; provided that no adjustment to the Conversion Rate will be made if the Holder will otherwise participate in such distribution on an as-converted basis in its capacity as a Noteholder without conversion in which case a Holder of a Note will not have the ability to convert pursuant to this Section 15.01(b); or

(ii) the Company consolidates with or merges with or into another Person or is a party to a binding share exchange or conveys, transfers, sells, leases or otherwise disposes of all or substantially all of its properties and assets in each case pursuant to which the Common Stock is converted into cash, securities or other property, then the holders shall have the right to convert Notes at any time beginning 30 scheduled Trading Days prior to the date announced by the Company as the anticipated effective date of the transaction and until and including the related Designated Event Repurchase Date (or, if such transaction does not constitute a Fundamental Change, until and including the date which is 15 days after the earlier of (a) the actual effective date of such transaction or (b) the date that the Company announces that the transaction will not take place). If such transaction constitutes a Fundamental Change of the type specified in Section 15.01(d), a holder converting Notes during the period specified in Section 15.01(d) shall also be entitled to any Additional Shares payable in connection with such conversion pursuant to Section 15.01(d). The Company will notify holders of Notes and the Trustee at least 30 scheduled Trading Days prior to the anticipated effective date of such transaction. The Board of Directors shall determine the anticipated effective date of the transaction, and such determination shall be conclusive and binding on the holders beginning on the effective date of the transaction, the right to convert the Notes into cash and Common Stock will convert into a right to convert the Notes into cash and Reference Property pursuant to, and in accordance with, Section 15.06. If such transaction also constitutes a Designated Event, a Noteholder may require the Company to repurchase all or a portion of such holder’s Notes pursuant to Section 3.05.

“Ex-Dividend Time” means, with respect to any distribution on shares of Common Stock, the first date on which the shares of Common Stock trade regular way on the principal securities market on which the shares of Common Stock are then traded without the right to receive such distribution.

(c) A Note in respect of which a holder is electing to exercise its option to require the Company to repurchase such holder’s Notes upon a Designated Event pursuant to Section 3.05, or at the option of the holder pursuant to Section 3.06, may be converted only if such holder withdraws its election in accordance with Section 3.05(c) or Section 3.08, respectively. A holder of Notes is not entitled to any rights of a holder of Common Stock until such holder has converted his Notes into Common Stock, and only to the extent such Notes are deemed to have been converted into Common Stock under this Article 15.

(d) (i) If a Noteholder elects to convert Notes in connection with a Fundamental Change that occurs prior to December 15, 2013, in which the consideration is not at least 90% common stock that is listed on or immediately after such Fundamental Change will be listed on, the New York Stock Exchange, the Nasdaq Stock Market or the American Stock Exchange, the Conversion Rate applicable to each $1,000 principal amount of Notes so converted shall be increased by an additional number of shares of Common Stock (the “Additional Shares”) as

described below. Settlement of Notes tendered for conversion to which Additional Shares shall be added to the Conversion Rate as provided in this subsection shall be settled pursuant to Section 15.02(d) below. For purposes of this Section 15.01(d), a conversion shall be deemed to be “in connection” with a Fundamental Change to the extent that such conversion is effected during the time period specified in Section 15.01(b)(ii).

(ii) The number of Additional Shares by which the Conversion Rate will be increased shall be determined by reference to the table attached as Schedule A hereto, based on the date on which the Fundamental Change occurs or becomes effective (the “Effective Date”), and the Stock Price; provided, however, that if the actual Stock Price is between two Stock Price amounts in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares shall be determined by a straight–line interpolation between the number of Additional Shares set forth for the next higher and next lower Stock Price amounts and the two nearest Effective Dates, as applicable, based on a 365/366 day year; provided further, however, that if (1) the Stock Price is greater than $50.00 per share of Common Stock (subject to adjustment in the same manner as set forth in Section 15.05), no Additional Shares will be added to the Conversion Rate, and (2) the Stock Price is less than $7.50 per share (subject to adjustment in the same manner as set forth in Section 15.05), 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 133.3333 per $1,000 principal amount of Notes (subject to adjustment in the same manner as set forth in Section 15.05).

(iii) The Stock Prices set forth in the first row of the table in Schedule A hereto shall be adjusted as of any date on which the Conversion Rate of the Notes is 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 in effect 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 within the table shall be adjusted in the same manner as the Conversion Rate as set forth in Section 15.05 (other than by operation of an adjustment to the Conversion Rate by adding Additional Shares).

SECTION 15.02. Exercise of Conversion Privilege; Settlement Upon Conversion; No Adjustment for Dividends. (a) In order to exercise the conversion privilege with respect to any Note in certificated form, the Company must receive at the office or agency of the Company maintained for that purpose or, at the option of such holder, the Corporate Trust Office, such Note with the original or facsimile of the form entitled “Conversion Notice” on the reverse thereof, duly completed and manually signed, together with such Notes duly endorsed for transfer, accompanied by the funds, if any, required by Section 15.02(j)). Such notice shall also state the name or names (with address or addresses) in which the certificate or certificates for shares of Common Stock

which shall be issuable on such conversion shall be issued, and shall be accompanied by transfer or similar taxes, if required pursuant to Section 15.07.

In order to exercise the conversion privilege with respect to any interest in a Global Note, the beneficial holder must complete, or cause to be completed, the appropriate instruction form for conversion pursuant to the Depositary’s book-entry conversion program, deliver, or cause to be delivered, by book-entry delivery an interest in such Global Note, 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 15.02(j) and any transfer taxes if required pursuant to Section 15.07.

(b) Subject to Section 15.02(d) and subject to the Company’s right to pay the Net Share Amount in cash pursuant to Section 15.02(c), the Company will satisfy the Conversion Obligation with respect to each $1,000 principal amount of Notes tendered for conversion in cash and shares of Common Stock, if applicable, by delivering, on the third Trading Day immediately following the last day of the related Observation Period, cash and shares of Common Stock, if any, equal to the sum of the Daily Settlement Amounts for each of the 20 Trading Days during the related Observation Period; provided that the Company may deliver cash in lieu of fractional shares of Common Stock or a full share of Common Stock pursuant to Section 15.03. The Daily Settlement Amounts shall be determined by the Company promptly following the last day of the Observation Period.

(c) Notwithstanding Section 15.02(b), instead of delivering shares of Common Stock (or Reference Property following a Merger Event) in satisfaction of the Company’s obligation to deliver this Net Share Amount, the Company may elect to deliver to converting holders an additional amount of cash. If the Company so elects, the additional cash amount shall be equal to the sum of the amount, if any, by which Daily Conversion Value exceeds $50 on each of the 20 Trading Days during the related Observation Period. If the Company chooses to pay additional cash instead of the Net Share Amount, the Company will notify the Trustee and the holder through the Trustee of its election (such notice, the “Settlement Method Election Notice”) as follows: (i) if the Company has called Notes for redemption, in the applicable notice of redemption; (ii) if a Designated Event has occurred, in the applicable Designated Event Notice; and (iii) in all other cases, at any time on or before the date that is two Trading Days following the Conversion Date. If the Company does not timely provide the Settlement Method Election Notice, it shall settle the Net Share Amount in shares of Common Stock (or Reference Property following a Merger Event). The Company shall satisfy the obligation to deliver the Net Share Amount in respect of each Note with the same consideration to be provided in respect of the Net Share Amount in respect of all other Notes to be converted (i) after the Company has given a notice of redemption and prior to the corresponding redemption date; (ii) after the Company has given a Designated Event Notice and prior to the corresponding Designated Event Repurchase Date and (iii) on the same Conversion Date. Other than as set forth in the preceding sentence, the Company shall not have any obligation to satisfy its obligation to deliver the Net Share Amount arising on different Trading Days in the same manner. If the Company timely elects

to pay cash (other than cash in lieu of fractional shares) in satisfaction of its obligation to deliver the Net Share Amount, the Conversion Notice may be retracted by the holder at any time during the two Trading Day period (the “Conversion Retraction Period”) beginning on the Trading Day after the Company has given the Settlement Election Notice to the Trustee.

A Conversion Notice may be retracted during the applicable Conversion Retraction Period by means of a written notice of retraction delivered to the office of the Trustee (or other paying agent appointed by the Company) in accordance with the Settlement Method Election Notice at any time prior to the close of business of the final day of the Conversion Retraction Period, specifying:

(i) the certificate number, if any, of the Note in respect of which such retraction notice is being submitted, or the appropriate Depositary information if the Note in respect of which such retraction notice is being submitted is represented by a Global Note,

(ii) the principal amount of the Note with respect to which such retraction notice of is being submitted, and

(iii) the principal amount, if any, of such Note which remains subject to the original Conversion Notice and which has been or will be delivered for conversion.

(d) Notwithstanding Section 15.02(b), the Company shall satisfy the Conversion Obligation with respect to each $1,000 principal amount of Notes tendered for conversion to which Additional Shares shall be added to the Conversion Rate as set forth in Section 15.01(d) pursuant to this paragraph (d).

(i) If the last day of the applicable Observation Period related to Notes surrendered for conversion is prior to the third Trading Day preceding the Effective Date of the Fundamental Change, the Company will satisfy the related Conversion Obligation with respect to each $1,000 principal amount of Notes tendered for conversion by delivering the cash and shares of Common Stock (based on the Conversion Rate, but without regard to the number of Additional Shares to be added to the Conversion Rate pursuant to this Section 15.02(d)) on the third Trading Day immediately following the last day of the applicable Observation Period. As soon as practicable following the Effective Date of the Fundamental Change, the Company will deliver the increase in such amount of cash and Reference Property in lieu of shares of Common Stock, if any, as if the Conversion Rate had been increased by such number of Additional Shares during the related Observation Period (and based upon the related Daily VWAP prices during such Observation Period). If such increased amount of cash and shares, if any, results in an increase to the amount of cash to be paid to holders, the Company will pay such increase in cash, and if such increased amount results in an increase to the number of shares of Common Stock, the Company will deliver

such increase by delivering Reference Property based on such increased number of shares.

(ii) If the last day of the applicable Observation Period related to Notes surrendered for conversion is on or following the third scheduled Trading Day preceding the Effective Date of such Fundamental Change, the Company will satisfy the Conversion Obligation with respect to each $1,000 principal amount of Notes tendered for conversion (based on the Conversion Rate as increased by the Additional Shares pursuant to Section 15.02(d) above) on the later to occur of (1) the Effective Date of the Fundamental Change and (2) the third Trading Day immediately following the last day of the applicable Observation Period.

(e) Each conversion shall be deemed to have been effected as to any such Note (or portion thereof) on the date (the “Conversion Date”) on which the requirements set forth above in this Section 15.02 have been satisfied as to such Note (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 any such surrender on any date when the stock transfer books of the Company shall be closed shall constitute the Person in whose name the certificates are to be issued as the record holder thereof for all purposes on the next succeeding day on which such stock transfer books are open, but such conversion shall be at the Conversion Rate in effect on the date upon which such Note shall be surrendered.

(f) Upon the conversion of an interest in a Global Note, the Trustee (or other conversion agent appointed by the Company), or the Custodian at the direction of the Trustee (or other conversion agent appointed by the Company), shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Notes effected through any conversion agent other than the Trustee.

(g) Delivery of the amounts owing in satisfaction of the Conversion Obligation shall be made by the Company in no event later than the date specified in Section 15.02(b), except to the extent specified in Section 15.02(c) or 15.02(d). The Company shall make such delivery by paying the cash amount owed to the Conversion Agent or to the holder of the Note surrendered for conversion, or such holder’s nominee or nominees, and by issuing, or causing to be issued, and delivering to the Conversion Agent or to such holder, or such holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of Common Stock to which such holder shall be entitled as part of such Conversion Obligation (together with any cash in lieu of fractional shares).

(h) In case any Note of a denomination greater than $1,000 shall be surrendered for partial conversion, subject to Section 2.03, the Company shall execute and the Trustee shall authenticate and deliver to the holder of the Note so surrendered, without charge to such holder, a new Note or Notes in authorized

denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note.

(i) Except as provided in Section 15.05, no adjustment shall be made for dividends on any shares of Common Stock issued upon the conversion of any Note as provided in this Article.

(j) Upon conversion, a Noteholder will not receive any separate cash payment for accrued and unpaid interest and Additional Interest, if any, except as set forth below. The Company’s settlement of the Conversion Obligations in accordance with this Article 15 shall be deemed to satisfy its obligation to pay the principal amount of the Notes that are converted and accrued and unpaid interest and Additional Interest, if any, in respect of such Notes. As a result, accrued and unpaid interest and Additional Interest, if any, to, but not including, the Conversion Date shall be deemed to be paid in full rather than canceled, extinguished or forfeited. Notwithstanding the preceding sentence, if Notes are converted after the close of business on a Regular Record Date, holders of such Notes as of the close of business on the Regular Record Date will receive the interest and Additional Interest, if any, payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the opening of business on the corresponding Interest Payment Date must be accompanied by payment of an amount equal to the interest and Additional Interest, if any, payable on the Notes so converted; provided, however, that no such payment need be made (1) if the Company has specified a redemption date that is after such Regular Record Date and on or prior to the corresponding Interest Payment Date, (2) if the Company has specified a Designated Event Repurchase Date that is after such Regular Record Date and on or prior to the corresponding Interest Payment Date or (3) to the extent of any overdue interest or Additional Interest, if any, existing at the time of conversion with respect to such Note. Except as described above, no payment or adjustment will be made for accrued interest on converted Notes.

SECTION 15.03. Cash Payments in Lieu of Fractional Shares. No fractional shares of Common Stock or scrip certificates representing fractional shares shall be issued upon conversion of Notes. If more than one Note shall be surrendered for conversion at one time by the same holder, the number of full shares that shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (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 Note or Notes, the Company shall make an adjustment and payment therefor in cash at the current market price thereof to the holder of Notes; provided that at the Company’s option, the Company may issue one share of its Common Stock in lieu of paying cash for any fractional interest in respect of a share of Common Stock. The current market price of a share of Common Stock shall be the Closing Sale Price on the last Trading Day immediately preceding the Conversion Date.

SECTION 15.04. Conversion Rate. Each $1,000 principal amount of the Notes shall be convertible into the number of shares of Common Stock specified in the form of Note (herein called the “Conversion Rate”) attached as Exhibit A hereto, subject to adjustment as provided in this Article 15.

SECTION 15.05. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows:

(a) In case the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect at the opening of business on the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution by a fraction,

(i) the numerator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on the date fixed for the determination of stockholders entitled to receive such dividend or other distribution plus the total number of shares of Common Stock constituting such dividend or other distribution; and

(ii) the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination,

such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purpose of this paragraph (a), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. If any dividend or distribution of the type described in this Section 15.05(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) In case the Company shall issue rights or warrants to all holders of its outstanding shares of Common Stock entitling them (for a period expiring within forty-five (45) days after the date fixed for determination of stockholders entitled to receive such rights or warrants) to subscribe for or purchase shares of Common Stock at a price per share less than the average of the Closing Sale Prices of the Common Stock for the 10 Trading Days immediately preceding the date such distribution is first publicly announced by the Company, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the date fixed for determination of stockholders entitled to receive such rights or warrants by a fraction,

(i) the numerator of which shall be the number of shares of Common Stock outstanding on the date fixed for determination of stockholders entitled to receive

such rights or warrants plus the total number of additional shares of Common Stock offered for subscription or purchase, and

(ii) the denominator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on the date fixed for determination of stockholders entitled to receive such rights or warrants plus the number of shares that the aggregate offering price of the total number of shares so offered would purchase at a price equal to the average of the Closing Sale Prices of the Common Stock for the 10 Trading Days immediately preceding the date such distribution is first publicly announced by the Company,

such adjustment shall be successively made whenever any such rights or warrants are issued, and shall become effective immediately after the opening of business on the day following the date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock are not delivered after the expiration of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of 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 that would then be in effect if such 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 a price less than the average of the Closing Sale Prices of the Common Stock for the 10 Trading Days immediately preceding the date such distribution is first publicly announced by the Company, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

(c) In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately increased, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective.

(d) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital stock of the Company or evidences of its indebtedness or assets (including cash or securities, but excluding any rights or warrants referred to in Section 15.05(b), and excluding any dividend or distribution (x) paid exclusively in cash or (y) referred to in Section 15.05(a) (any of

the foregoing hereinafter in this Section 15.05(d)) called the “Securities”)), then, in each such case (unless the Company elects to reserve such Securities for distribution to the Noteholders upon the conversion of the Notes so that any such holder converting Notes will receive upon such conversion, in addition to the shares of Common Stock to which such holder is entitled, the amount and kind of such Securities which such holder would have received if such holder had converted its Notes into Common Stock immediately prior to the Record Date (as defined below) for such distribution of the Securities) the Conversion Rate shall be increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect on the Record Date with respect to such distribution by a fraction,

(i) the numerator of which shall be the Current Market Price on such Record Date; and

(ii) the denominator of which shall be the Current Market Price on such Record Date less the Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors) on the Record Date of the portion of the Securities so distributed applicable to one share of Common Stock,

such adjustment to become effective immediately prior to the opening of business on the day following such Record Date; provided that if the then Fair Market Value (as so determined) of the portion of the Securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the right to receive upon conversion the amount of Securities such holder would have received had such holder converted each Note on the Record Date. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 15.05(d) 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 Current Market Price on the applicable Record Date. Notwithstanding the foregoing, if the Securities distributed by the Company to all holders of its Common Stock consist of capital stock of, or similar equity interests in, a Subsidiary or other business unit, the Conversion Rate shall be increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect on the Record Date with respect to such distribution by a fraction,

(iii) the numerator of which shall be the sum of (A) the average of the Closing Sale Prices of the Common Stock for the ten (10) Trading Days commencing on and including the fifth Trading Day after the Ex-Dividend Time plus (B) the Fair Market Value of the securities distributed in respect of each share of Common Stock for which this Section 15.05(d) applies and shall equal the number of securities distributed in respect of each share of Common Stock multiplied by the average of the closing sale prices of those securities distributed (where such

closing sale prices are available) for the ten (10) Trading Days commencing on and including the fifth Trading Day after the Ex-Dividend Time; and

(iv) the denominator of which shall be the average of the Closing Sale Prices of the Common Stock for the ten (10) Trading Days commencing on and including the fifth Trading Day after the Ex-Dividend Time,

such adjustment to become effective immediately prior to the opening of business on the day following such Record Date; provided that the Company may in lieu of the foregoing adjustment make adequate provision so that each Noteholder shall have the right to receive upon conversion the amount of Securities such holder would have received had such holder converted each Note on the Record Date with respect to such distribution.

Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 15.05 (and no adjustment to the Conversion Rate under this Section 15.05 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 this Section 15.05(d). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 15.05 was made, (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that 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.

No adjustment of the Conversion Rate shall be made pursuant to this Section 15.05(d) in respect of rights or warrants distributed or deemed distributed on any

Trigger Event to the extent that such rights or warrants are actually distributed, or reserved by the Company for distribution to holders of Notes upon conversion by such holders of Notes to Common Stock.

For purposes of this Section 15.05(d) and Section 15.05(a) and (b), any dividend or distribution to which this Section 15.05(d) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets or shares of capital stock other than such shares of Common Stock or rights or warrants (and any Conversion Rate adjustment required by this Section 15.05(d) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Rate adjustment required by Sections 15.05(a) and 15.05(b) with respect to such dividend or distribution shall then be made), except (A) the Record Date of such dividend or distribution shall be substituted as “the date fixed for the determination of stockholders entitled to receive such dividend or other distribution”, “the date fixed for the determination of stockholders entitled to receive such rights or warrants” and “the date fixed for such determination” within the meaning of Section 15.05(a) and 15.05(b) and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of business on the date fixed for such determination” within the meaning of Section 15.05(a).

(e) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary), then, in such case, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on such Record Date by a fraction,

(i) the numerator of which shall be the Current Market Price on such Record Date; and

(ii) the denominator of which shall be the Current Market Price on such Record Date less the amount of cash so distributed applicable to one share of Common Stock,

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

(f) In case a tender or exchange offer made by the Company or any Subsidiary for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders of consideration per share of Common Stock having a Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive and described in a resolution of the Board of Directors) that as of the last time (the “Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended) exceeds the Closing Sale Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the Expiration Time by a fraction,

(i) the numerator of which shall be the sum of (x) the Fair Market Value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted up to any such maximum, being referred to as the “Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) at the Expiration Time and the Closing Sale Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time, and

(ii) the denominator of which shall be the number of shares of Common Stock outstanding (including the Purchased Shares) at the Expiration Time multiplied by the Closing Sale Price of a share of Common Stock on the Trading Day next succeeding the Expiration Time,

such adjustment to become effective immediately prior to the opening of business on the day following the Expiration Time. 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 offer had not been made.

(g) In addition, the Conversion Rate shall be adjusted to the extent required by Section 2(e) of the Registration Rights Agreement.

(h) For purposes of this Section 15.05, the following terms shall have the meaning indicated:

(i) “Current Market Price” shall mean the average of the daily Closing Sale Prices per share of Common Stock for the ten consecutive Trading Days ending on the earlier of such date of determination and the day before the “ex” date with respect to the issuance, distribution, subdivision or combination requiring such computation immediately prior to the date in question. For purpose of this

paragraph, the term “ex” date, (1) when used with respect to any issuance or distribution, means the first date on which the Common Stock trades, regular way, on the relevant exchange or in the relevant market from which the Closing Sale Price was obtained without the right to receive such issuance or distribution, and (2) when used with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades, regular way, on such exchange or in such market after the time at which such subdivision or combination becomes effective.

If another issuance, distribution, subdivision or combination to which Section 15.05 applies occurs during the period applicable for calculating “Current Market Price” pursuant to the definition in the preceding paragraph, “Current Market Price” shall be calculated for such period in a manner determined by the Board of Directors to reflect the impact of such issuance, distribution, subdivision or combination on the Closing Sale Price of the Common Stock during such period.

(ii) “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).

(iii) “Trading Day” shall mean (x) if the applicable security is listed or admitted for trading on the Nasdaq Global Stock Market, American Stock Exchange, New York Stock Exchange or another national securities exchange, a day on which the Nasdaq Global Stock Market, American Stock Exchange, New York Stock Exchange or another national securities exchange is open for business, (y) if the applicable security is quoted on any United States system of automated dissemination of quotations, a day on which trades may be made thereon or (z) if the applicable security is not so listed, admitted for trading or quoted, any day other than a Saturday or Sunday or a day on which banking institutions in the State of New York are authorized or obligated by law or executive order to close.

(i) The Company may make such increases in the Conversion Rate, in addition to those required by Section 15.05(a), (b), (c), (d), (e), or (f) as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes.

To the extent permitted by applicable law and Nasdaq Stock Market rules, the Company from time to time may increase the Conversion Rate by any amount for any period of time 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 the preceding sentence, the Company shall mail to holders of record of the Notes a notice of the increase, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(j) No adjustment in the Conversion Rate shall be required unless such adjustment would require an increase or decrease of at least one percent (1.00%) in such rate; provided that any adjustments that by reason of this Section 15.05(j) are not required to be made shall be carried forward and taken into account in any subsequent adjustment; provided further that this paragraph (j) shall not apply to any Conversion Rate Increase Amount required to be effected or paid in the Registration Rights Agreement. All calculations under this Article 15 shall be made by the Company and shall be made to the nearest cent or to the nearest one-ten thousandth (1/10,000) of a share, as the case may be. No adjustment need be made for rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest or for any issuance of Common Stock or convertible or exchangeable securities or rights to purchase Common Stock or convertible or exchangeable securities. To the extent the Notes become convertible into cash, assets, property or securities (other than capital stock of the Company), no adjustment need be made thereafter as to the cash, assets, property or such securities. Interest will not accrue on any cash into which the Notes are convertible.

(k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any conversion agent other than the Trustee 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 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 the holder of each Note at his last address appearing on the Note Register provided for in Section 2.05 of this Indenture, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(l) In any case in which this Section 15.05 provides that an adjustment shall become effective immediately after (1) a record date or Record Date for an event, (2) the date fixed for the determination of stockholders entitled to receive a dividend or distribution pursuant to Section 15.05(a), (3) a date fixed for the determination of stockholders entitled to receive rights or warrants pursuant to Section 15.05(b), or (4) the Expiration Time for any tender or exchange offer pursuant to Section 15.05(f), (a “Determination Date”), the Company may elect to defer until the occurrence of the applicable Adjustment Event (as hereinafter defined) (x) issuing to the holder of any Note converted after such Determination Date and before the occurrence of such

Adjustment Event, the additional shares of Common Stock or other securities issuable upon such conversion by reason of the adjustment required by such Adjustment Event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (y) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 15.03. For purposes of this Section 15.05(l), the term “Adjustment Event” shall mean:

(i) in any case referred to in clause (1) hereof, the occurrence of such event,

(ii) in any case referred to in clause (2) hereof, the date any such dividend or distribution is paid or made,

(iii) in any case referred to in clause (3) hereof, the date of expiration of such rights or warrants, and

(iv) in any case referred to in clause (4) hereof, the date a sale or exchange of Common Stock pursuant to such tender or exchange offer is consummated and becomes irrevocable.

(m) For purposes of this Section 15.05, the number of shares of Common Stock at any time outstanding shall not include shares 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. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company.

(n) The Company shall not take any action that would result in an adjustment of the Conversion Rate pursuant to this Section 15.05 without complying with the shareholder approval rules of the Nasdaq Global Select Market.

SECTION 15.06. Effect of Reclassification, Consolidation, Merger or Sale. (a) If any of the following events (each a “Merger Event”) occur, namely (i) any reclassification or change of the outstanding shares of Common Stock (other than a subdivision or combination to which Section 15.05(c) applies), (ii) any consolidation, merger or combination of the Company with another Person as a result of which holders of Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, or (iii) any sale or conveyance of all or substantially all of the properties and assets of the Company to any other Person as a result of which holders of Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, then 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 Note shall be convertible into cash and Reference Property as set forth in Section 15.06(b). 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 15.

(b) Notwithstanding the provisions of Section 15.02, and subject to the provisions of Section 15.01(d), at the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes will be changed to a right to convert such Note by reference to the kind and amount of cash, securities or other property or assets that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such transaction would have been entitled to receive in such Merger Event (the “Reference Property”) such that from and after the effective time of such transaction, a Noteholder will be entitled thereafter to convert its Notes, based on the applicable Conversion Rate, into cash (up to the aggregate principal amount thereof) and, instead of the shares of Common Stock otherwise deliverable in satisfaction of the Net Share Amount, units of Reference Property, based on the Daily Conversion Value of the units of Reference Property.

(c) In the event holders of Common Stock have the opportunity to elect the form of consideration to be received in any Merger Event, the Company shall make adequate provision whereby the Holders shall have a reasonable opportunity to determine the form of Reference Property that shall be used for purposes of determining the Daily Conversion Value and in which the Net Share Amount in respect of which all of the Notes, treated as a single class, shall be payable from and after the effective date of such Merger Event, subject to the Company’s right to elect to pay the net Share Amount in additional cash pursuant to Section 15.02(c). This provision does not limit the right of Holders in the event of a Fundamental Change, including Company’s obligation to increase the Conversion Rate by the Additional Shares in connection with a conversion. The determination: (a) will be made by Holders representing a plurality of Notes participating in such determination, (b) will be subject to any limitations to which all of the holders of Common Stock are subject, including, but not limited to, pro rata reductions applicable to any portion of the Reference Property payable in such Transaction and (c) will be conducted in such a manner as to be completed by the date which is the earlier of: (1) the deadline for elections to be made by holders of Common Stock, and (2) two Trading Days prior to the anticipated effective date of such Merger Event.

(d) The Company shall cause notice of the execution of such supplemental indenture to be mailed to each holder of Notes, at its address appearing on the Note Register provided for in Section 2.05 of this Indenture, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(e) The above provisions of this Section shall similarly apply to successive Merger Events.

(f) If this Section 15.06 applies to any Merger Event, Section 15.05 shall not apply.

SECTION 15.07. Taxes on Shares Issued. The issue of stock certificates on conversions of Notes shall be made without charge to the converting Noteholder for any documentary, stamp or similar issue or transfer tax in respect of the issue thereof. 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 Note 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 15.08. Reservation of Shares, Shares to Be Fully Paid; 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 Notes from time to time as such Notes are presented for conversion.

Before taking any action which 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 Notes, 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 Rate.

The Company covenants that all shares of Common Stock which may be issued upon conversion of Notes will upon issue be fully paid and non-assessable by the Company and free from all taxes, Liens and charges with respect to the issue thereof.

The Company further covenants that it will, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as the Common Stock shall be so listed on all Common Stock issuable upon conversion of the Notes; provided that if the rules of the Nasdaq Global Select Market (or such other national securities exchange or automated quotation system) permit the Company to defer the listing of such Common Stock until the first conversion of the Notes into Common Stock in accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Notes in accordance with the requirements of such exchange or automated quotation system at such time.

SECTION 15.09. Responsibility of Trustee. The Trustee and any other conversion agent shall not at any time be under any duty or responsibility to any holder of Notes 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, or herein or in any amendment or 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 Note; 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 Note

for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 15. 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 amendment or supplemental indenture entered into pursuant to Section 15.06 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Noteholders upon the conversion of their Notes after any event referred to in such Section 15.06 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 8.01, 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 amendment or supplemental indenture) with respect thereto.

SECTION 15.10. 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 15.05; or

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

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

the Company shall cause to be filed with the Trustee and to be mailed to each holder of Notes at his address appearing on the Note Register provided for in Section 2.05 of this Indenture, as promptly as possible but in any event at least ten (10) 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 are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, 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, consolidation, merger, sale, 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, consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

SECTION 15.11. Shareholder Rights Plans. Each share of Common Stock issued upon conversion of Notes pursuant to this Article 15 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 shareholder 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 shareholder rights agreement so that the holders of the Notes would not be entitled to receive any rights in respect of Common Stock issuable upon conversion of the Notes, the Conversion Rate will be adjusted in accordance with Section 15.05(d) treating all rights previously issued as Securities for purposes of such adjustment, subject to readjustment in the event of the expiration, termination or redemption of the rights.

ARTICLE 16

SUBORDINATION

SECTION 16.01. Agreement to Subordinate. The Company agrees, and each Noteholder by accepting a Note agrees, that the Indebtedness evidenced by the Notes is subordinated in right of payment, to the extent and in the manner provided in this Article 16, to the prior payment in full of all Senior Indebtedness of the Company and that the subordination is for the benefit of and enforceable by the holders of such Senior Indebtedness. The Notes shall in all respects rank pari passu in right of payment with all other Senior Subordinated Indebtedness of the Company and shall rank senior to all existing and future Subordinated Obligations of the Company; and only Indebtedness of the Company that is Senior Indebtedness of the Company shall rank senior to the Notes in accordance with the provisions set forth herein. All provisions of this Article 16 shall be subject to Section 16.12.

SECTION 16.02. Liquidation, Dissolution, Bankruptcy. Upon any payment or distribution of the assets of the Company to its respective creditors upon a total or partial liquidation or a total or partial dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property:

(a) holders of Senior Indebtedness of the Company shall be entitled to receive payment in full of such Senior Indebtedness before Noteholders shall be entitled to receive any payment of principal of or interest, if any, on the Notes; and

(b) until the Senior Indebtedness of the Company is paid in full, any payment or distribution to which Noteholders would be entitled but for this Article 16 shall be made to holders of such Senior Indebtedness as their interests may appear, except that Noteholders may receive shares of stock and any debt securities that are subordinated to such Senior Indebtedness to at least the same extent as the Notes.

SECTION 16.03. Default on Senior Indebtedness. The Company may not pay the principal, interest (including Additional Interest), or premium (if any) on the Notes, make any deposit pursuant to Section 13.02 or otherwise repurchase, redeem or otherwise retire any Notes (collectively, “pay the Notes”) if (a) any Designated Senior Indebtedness of the Company is not paid when due or (b) any other default on such Designated Senior Indebtedness occurs and the maturity of such Designated Senior Indebtedness is accelerated in accordance with its terms unless, in either case, (i) the default has been cured or waived and any such acceleration has been rescinded or (ii) such Designated Senior Indebtedness has been paid in full; provided, however, that the Company may pay the Notes without regard to the foregoing if the Company and the Trustee receive written notice approving such payment from the Representative of such Designated Senior Indebtedness with respect to which either of the events set forth in clause (a) or (b) of this sentence has occurred and is continuing.

During the continuance of any default (other than a default described in clause (a) or (b) of the preceding sentence) with respect to any Designated Senior Indebtedness of the Company pursuant to which the maturity thereof may be accelerated immediately without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, the Company may not pay the Notes for a period (a “Payment Blockage Period”) commencing upon the receipt by the Trustee (with a copy to the Company) of written notice (a “Blockage Notice”) of such default from the Representative of such Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period and ending 179 days thereafter (or earlier if such Payment Blockage Period is terminated (a) by written notice to the Trustee and the Company from the Person or Persons who gave such Blockage Notice, (b) by repayment in full of such Designated Senior Indebtedness or (c) because no default with respect to any Designated Senior Indebtedness is continuing). Notwithstanding the provisions described in the immediately preceding sentence (but subject to the provisions contained in the first sentence of this Section 16.03), the Company may resume payments on the Notes after the end of such Payment Blockage Period, unless the holders of such Designated Senior Indebtedness or the Representative of such holders shall have accelerated the maturity of such Designated Senior Indebtedness, and such Designated Senior Indebtedness has not been repaid in full.

Not more than one Blockage Notice may be given in any period of 360 consecutive days, irrespective of the number of defaults with respect to Designated Senior Indebtedness during such period; provided, however, that if any Blockage Notice within such 360-day period is given by or on behalf of any holders of Designated Senior Indebtedness other than the Bank Indebtedness, the Representative of the Bank Indebtedness may give another Blockage Notice within such period; provided further, however, that in no event may the total number of days during which any Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during any period of 360 consecutive days. For purposes of this Section 16.03, no default or event of default that existed or was continuing on the date of the commencement of any Payment Blockage Period with respect to the Designated Senior Indebtedness initiating such Payment Blockage Period shall be, or be made, the basis of the commencement of a subsequent Payment Blockage Period by the Representative of such Designated Senior

Indebtedness, whether or not within a period of 360 consecutive days, unless such default or event of default shall have been cured or waived for a period of not less than 90 consecutive days.

SECTION 16.04. Acceleration of Payment of Notes. If payment of the Notes is accelerated because of an Event of Default, the Trustee (provided, that the Trustee shall have received written notice from the Company or a Representative identifying the Designated Senior Indebtedness for which such Representative is so designated, on which notice the Trustee shall be entitled to rely conclusively) shall promptly notify the holders of each Company’s Designated Senior Indebtedness (or their Representative) of the acceleration. If any such Designated Senior Indebtedness of the Company is outstanding, the Company may not pay the Notes until five Business Days after such holders or the Representative of such Designated Senior Indebtedness receive notice of such acceleration and, thereafter, may pay the Notes only if this Article 16 otherwise permits payment at that time.

SECTION 16.05. When Distribution Must Be Paid Over. If a payment or distribution is made to Noteholders that because of this Article 16 should not have been made to them, the Noteholders who receive the payment or distribution shall hold it in trust for holders of Senior Indebtedness of the Company and pay it over to them as their interests may appear.

SECTION 16.06. Subrogation. After all Senior Indebtedness of the Company is paid in full and until the Notes are paid in full, Noteholders shall be subrogated to the rights of holders of such Senior Indebtedness to receive distributions applicable to Senior Indebtedness. A distribution made under this Article 16 to holders of such Senior Indebtedness which otherwise would have been made to Noteholders is not, as between the Company and Noteholders, a payment by the Company on such Senior Indebtedness.

SECTION 16.07. Relative Rights. This Article 16 defines the relative rights of Noteholders and holders of Senior Indebtedness of the Company. Nothing in this Indenture shall:

(a) impair, as between the Company and Noteholders, the obligation of the Company, which is absolute and unconditional, to pay principal of and interest, if any, on the Notes in accordance with their terms; or

(b) prevent the Trustee or any Noteholder from exercising its available remedies upon a Default, subject to the rights of holders of Senior Indebtedness of the Company to receive distributions otherwise payable to Noteholders.

SECTION 16.08. Subordination May Not Be Impaired by Company. No right of any holder of Senior Indebtedness of the Company to enforce the subordination of the Indebtedness evidenced by the Notes shall be impaired by any act or failure to act by the Company or by its failure to comply with this Indenture.

SECTION 16.09. Rights of Trustee and Paying Agent. Notwithstanding Section 16.03, the Trustee or paying agent may continue to make payments on the Notes

and shall not be charged with knowledge of the existence of facts that would prohibit the making of any such payments unless, not less than two Business Days prior to the date of such payment, a Responsible Officer of the Trustee receives written notice satisfactory to it that payments may not be made under this Article 16. The Company, the Note Registrar, the paying agent, a Representative or a holder of Senior Indebtedness of the Company (as identified by the Company) may give the notice; provided, however, that, if an issue of Senior Indebtedness of the Company has a Representative, only the Representative may give the notice.

The Trustee in its individual or any other capacity may hold Senior Indebtedness of the Company with the same rights it would have if it were not Trustee. The Note Registrar and the paying agent may do the same with like rights. The Trustee shall be entitled to all the rights set forth in this Article 16 with respect to any Senior Indebtedness of the Company which may at any time be held by it, to the same extent as any other holder of such Senior Indebtedness; and nothing in Article 8 shall deprive the Trustee of any of its rights as such holder. Nothing in this Article 16 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 8.06 or any other Section of this Indenture.

SECTION 16.10. Distribution or Notice to Representative. Whenever a distribution is to be made or a notice given to holders of Senior Indebtedness of the Company, the distribution may be made and the notice given to their Representative (if any).

SECTION 16.11. Article 16 Not to Prevent Events of Default or Limit Right to Accelerate. The failure to make a payment pursuant to the Notes by reason of any provision in this Article 16 shall not be construed as preventing the occurrence of a Default. Nothing in this Article 16 shall have any effect on the right of the Noteholders or the Trustee to accelerate the maturity of the Notes.

SECTION 16.12. Trust Monies Not Subordinated. Notwithstanding anything contained herein to the contrary, payments from money or the proceeds of U.S. Government Obligations held in trust under Article 13 by the Trustee for the payment of principal of the Notes shall not be subordinated to the prior payment of any Senior Indebtedness of the Company or subject to the restrictions set forth in this Article 16, and none of the Noteholders shall be obligated to pay over any such amount to the Company or any holder of Senior Indebtedness of the Company or any other creditor of the Company.

SECTION 16.13. Trustee Entitled to Rely. Upon any payment or distribution pursuant to this Article 16, the Trustee and the Noteholders shall be entitled to rely (a) upon any order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 16.02 are pending, (b) upon a certificate of the liquidating trustee or agent or other Person making such payment or distribution to the Trustee or to the Noteholders or (c) upon the Representatives for the holders of Senior Indebtedness of the Company for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of such Senior Indebtedness and

other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 16. In the event that the Trustee determines, in good faith, that evidence is required with respect to the right of any Person as a holder of Senior Indebtedness of the Company to participate in any payment or distribution pursuant to this Article 16, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of such Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and other facts pertinent to the rights of such Person under this Article 16, 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. The provisions of Sections 8.01 and 8.02 shall be applicable to all actions or omissions of actions by the Trustee pursuant to this Article 16.

SECTION 16.14. Trustee to Effectuate Subordination. Each Noteholder by accepting a Note authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination between the Noteholders and the holders of Senior Indebtedness of the Company as provided in this Article 16 and appoints the Trustee as attorney-in-fact for any and all such purposes.

SECTION 16.15. Trustee Not Fiduciary for Noteholders of Senior Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness of the Company and shall not be liable to any such holders if it shall mistakenly pay over or distribute to Noteholders or the Company or any other Person, money or assets to which any holders of Senior Indebtedness of the Company shall be entitled by virtue of this Article 16 or otherwise.

SECTION 16.16. Reliance by Noteholders of Senior Indebtedness on Subordination Provisions. Each Noteholder by accepting a Note acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration to each holder of any Senior Indebtedness of the Company, whether such Senior Indebtedness was created or acquired before or after the issuance of the Notes, to acquire and continue to hold, or to continue to hold, such Senior Indebtedness and such holder of such Senior Indebtedness shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Indebtedness.

ARTICLE 17

NOTE GUARANTEES

SECTION 17.01. Note Guarantees. (a) Each Note Guarantor hereby jointly and severally irrevocably and unconditionally Guarantees, as a primary obligor and not merely as a surety, to each Noteholder and to the Trustee and its successors and assigns the full and punctual payment when due, whether at Stated Maturity, by acceleration, by redemption or otherwise, of all obligations of the Company under this Indenture (including obligations to the Trustee) and the Notes, whether for payment of principal or interest (including Additional Interest) of the Notes and all other monetary obligations of

the Company under this Indenture and the Notes, whether for fees, expenses, indemnification or otherwise (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Note Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from each such Note Guarantor, and that each such Note Guarantor shall remain bound under this Article 17 notwithstanding any extension or renewal of any Guaranteed Obligation.

(b) Each Note Guarantor waives presentation to, demand of payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Note Guarantor waives notice of any default under the Notes or the Guaranteed Obligations. The obligations of each Note Guarantor hereunder shall not be affected by (i) the failure of any Noteholder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Indenture, the Notes or any other agreement or otherwise; (ii) any extension or renewal of any thereof; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement; (iv) the release of any security held by any Noteholder or the Trustee for the Guaranteed Obligations or any of them; (v) the failure of any Noteholder or Trustee to exercise any right or remedy against any other Note Guarantor; or (vi) any change in the ownership of such Note Guarantor, except as provided in Section 17.02(b).

(c) Each Note Guarantor hereby waives any right to which it may be entitled to have its obligations hereunder divided among the Note Guarantors, such that such Note Guarantor’s obligations would be less than the full amount claimed. Each Note Guarantor hereby waives any right to which it may be entitled to have the assets of the Company first be used and depleted as payment of the Company’s or such Note Guarantor’s obligations hereunder prior to any amounts being claimed from or paid by such Note Guarantor hereunder. Each Note Guarantor hereby waives any right to which it may be entitled to require that the Company be sued prior to an action being initiated against such Note Guarantor.

(d) Each Note Guarantor further agrees that its Note Guarantee herein constitutes a guarantee of payment when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Noteholder or the Trustee to any security held for payment of the Guaranteed Obligations.

(e) The Note Guarantee of each Note Guarantor is, to the extent and in the manner set forth in Article 18, subordinated and subject in right of payment to the prior payment in full of the principal of and premium, if any, and interest on all Senior Indebtedness of the relevant Note Guarantor and is made subject to such provisions of this Indenture.

(f) Except as expressly set forth in Sections 17.02 and 17.06, the obligations of each Note Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Guaranteed

Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Note Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Noteholder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Notes or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Guaranteed Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Note Guarantor or would otherwise operate as a discharge of any Note Guarantor as a matter of law or equity.

(g) Each Note Guarantor agrees that its Note Guarantee shall remain in full force and effect until payment in full of all the Guaranteed Obligations. Each Note Guarantor further agrees that its Note Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest, if any, on any Guaranteed Obligation is rescinded or must otherwise be restored by any Noteholder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

(h) In furtherance of the foregoing and not in limitation of any other right which any Noteholder or the Trustee has at law or in equity against any Note Guarantor by virtue hereof, upon the failure of the Company to pay the Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, each Note Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Noteholders or the Trustee an amount equal to the unpaid amount of such Guaranteed Obligations and interest, if any, accrued thereon.

(i) Each Note Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Noteholders in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations and all obligations to which the Guaranteed Obligations are subordinated as provided in Article 18. Each Note Guarantor further agrees that, as between it, on the one hand, and the Noteholders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article 7 for the purposes of any Note Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 7, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Note Guarantor for the purposes of this Section 17.01.

(j) Each Note Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any Noteholder in enforcing any rights under this Section 17.01.

(k) Upon request of the Trustee, each Note Guarantor shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

SECTION 17.02. Limitation on Liability. (a) Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Note Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Note Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

(b) A Note Guarantee as to any Note Guarantor shall terminate and be of no further force or effect and such Note Guarantor shall be deemed to be released from all obligations under this Article 17 upon (i) the merger or consolidation of such Note Guarantor with or into any Person other than the Company or a Subsidiary or Affiliate of the Company where such Note Guarantor is not the surviving entity of such consolidation or merger, (ii) the sale by the Company or any Subsidiary of the Company of the Capital Stock of such Note Guarantor (or by any other Person as a result of a foreclosure of any Lien on such Capital Stock securing Senior Indebtedness), where, after such sale, such Note Guarantor is no longer a Subsidiary of the Company, (iii) the sale, conveyance or transfer of all or substantially all the assets of such Note Guarantor to another Person other than the Company or a Subsidiary or Affiliate of the Company; provided, however, that each such merger, consolidation, sale, conveyance or transfer shall comply with Article 12. At the request of the Company, the Trustee shall execute and deliver an appropriate instrument evidencing such release (in the form provided by the Company). Notwithstanding the foregoing, if the Credit Agreement so requires, any Note Guarantor that has Guaranteed Indebtedness under the Credit Agreement and is being released from its Guarantee thereunder will be simultaneously released from its Note Guarantee hereunder unless an Event of Default has occurred and is continuing.

SECTION 17.03. Successors and Assigns. This Article 17 shall be binding upon each Note Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee and the Noteholders and, in the event of any transfer or assignment of rights by any Noteholder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Notes shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

SECTION 17.04. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Noteholders in exercising any right, power or privilege under this Article 17 shall operate as a waiver thereof, nor shall a single or partial exercise thereof

preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Noteholders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 17 at law, in equity, by statute or otherwise.

SECTION 17.05. Modification. No modification, amendment or waiver of any provision of this Article 17, nor the consent to any departure by any Note Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Note Guarantor in any case shall entitle such Note Guarantor to any other or further notice or demand in the same, similar or other circumstances.

SECTION 17.06. Execution of Amendment or Supplemental Indenture for Future Note Guarantors. Each Subsidiary which is required to become a Note Guarantor pursuant to Section 5.08 shall promptly execute and deliver to the Trustee an amendment or supplemental indenture pursuant to which such Subsidiary shall become a Note Guarantor under this Article 17 and shall guarantee the Guaranteed Obligations. Concurrently with the execution and delivery of such amendment or supplemental indenture, the Company shall deliver to the Trustee an Opinion of Counsel and an Officers’ Certificate to the effect that such amendment or supplemental indenture has been duly authorized, executed and delivered by such Subsidiary and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Note Guarantee of such Note Guarantor is a legal, valid and binding obligation of such Note Guarantor, enforceable against such Note Guarantor in accordance with its terms and or to such other matters as the Trustee may reasonably request.

SECTION 17.07. Non-Impairment. The failure to endorse a Note Guarantee on any Note shall not affect or impair the validity thereof.

ARTICLE 18

SUBORDINATION OF THE NOTE GUARANTEES

SECTION 18.01. Agreement to Subordinate. Each Note Guarantor agrees, and each Noteholder by accepting a Note agrees, that the obligations of a Note Guarantor hereunder are subordinated in right of payment, to the extent and in the manner provided in this Article 18, to the prior payment in full of all Senior Indebtedness of such Note Guarantor and that the subordination is for the benefit of and enforceable by the holders of such Senior Indebtedness of such Note Guarantor. The obligations hereunder with respect to a Note Guarantor shall in all respects rank pari passu in right of payment with all other Senior Subordinated Indebtedness of such Note Guarantor and shall rank senior to all existing and future Subordinated Obligations of such Note Guarantor; and only Indebtedness of such Note Guarantor that is Senior Indebtedness of such Note Guarantor shall rank senior to the obligations of such Note Guarantor in accordance with the provisions set forth herein.

100

SECTION 18.02. Liquidation, Dissolution, Bankruptcy. Upon any payment or distribution of the assets of a Note Guarantor to creditors upon a total or partial liquidation or a total or partial dissolution of such Note Guarantor or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to such Note Guarantor and its property:

(a) holders of Senior Indebtedness of such Note Guarantor shall be entitled to receive payment in full of such Senior Indebtedness before Noteholders shall be entitled to receive any payment pursuant to any Guaranteed Obligations from such Note Guarantor; and

(b) until the Senior Indebtedness of such Note Guarantor is paid in full, any payment or distribution to which Noteholders would be entitled but for this Article 18 shall be made to holders of such Senior Indebtedness as their respective interests may appear, except that Noteholders may receive shares of stock and any debt securities that are subordinated to such Senior Indebtedness to at least the same extent as the Note Guarantees.

SECTION 18.03. Default on Designated Senior Indebtedness of a Note Guarantor. A Note Guarantor may not make any payment pursuant to any of the Guaranteed Obligations or repurchase, redeem or otherwise retire any Notes (collectively, “pay its Guarantee”) if (a) any Designated Senior Indebtedness of such Note Guarantor is not paid when due or (b) any other default on Designated Senior Indebtedness of such Note Guarantor occurs and the maturity of such Designated Senior Indebtedness is accelerated in accordance with its terms unless, in either case, (i) the default has been cured or waived and any such acceleration has been rescinded or (ii) such Designated Senior Indebtedness has been paid in full; provided, however, that such Note Guarantor may pay its Guarantee without regard to the foregoing if such Note Guarantor and the Trustee receive written notice approving such payment from the Representative of the holders of such Designated Senior Indebtedness with respect to which either of the events in clause (a) or (b) of this sentence has occurred and is continuing.

During the continuance of any default (other than a default described in clause (a) or (b) of the preceding sentence) with respect to any Designated Senior Indebtedness of a Note Guarantor pursuant to which the maturity thereof may be accelerated immediately without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, such Note Guarantor may not pay its Guarantee for a period (a “Guarantee Payment Blockage Period”) commencing upon the receipt by the Trustee (with a copy to such Note Guarantor and the Company) of written notice (a “Guarantee Blockage Notice”) of such default from the Representative of the holders of the Designated Senior Indebtedness of such Note Guarantor specifying an election to effect a Guarantee Payment Blockage Period and ending 179 days thereafter (or earlier if such Guarantee Payment Blockage Period is terminated (a) by written notice to the Trustee (with a copy to such Note Guarantor and the Company) from the Person or Persons who gave such Guarantee Blockage Notice, (b) by repayment in full of such Designated Senior Indebtedness or (c) because no default with respect to any Designated Senior Indebtedness is continuing). Notwithstanding the provisions described

101

in the immediately preceding sentence (but subject to the provisions contained in the first sentence of this Section 18.03), such Note Guarantor may resume payments with respect to its Note Guarantee after the end of such Guarantee Payment Blockage Period, unless the holders of such Designated Senior Indebtedness or the Representative of such holders shall have accelerated the maturity of such Designated Senior Indebtedness and such Designated Senior Indebtedness has not been repaid in full.

Not more than one Guarantee Blockage Notice may be given with respect to a Note Guarantor in any period of 360 consecutive days, irrespective of the number of defaults with respect to Designated Senior Indebtedness of such Note Guarantor during such period; provided, however, that if any Guarantee Blockage Notice within such 360-day period is given by or on behalf of any holders of Designated Senior Indebtedness of such Note Guarantor other than the Bank Indebtedness, the Representative of the Bank Indebtedness may give another Guarantee Blockage Notice within such period; provided further, however, that in no event may the total number of days during which any Guarantee Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during any period of 360 consecutive days. For purposes of this Section 18.03, no default or event of default that existed or was continuing on the date of the commencement of any Guarantee Payment Blockage Period with respect to the Designated Senior Indebtedness initiating such Guarantee Payment Blockage Period shall be, or be made, the basis of the commencement of a subsequent Guarantee Payment Blockage Period by the Representative of such Designated Senior Indebtedness, whether or not within a period of 360 consecutive days, unless such default or event of default shall have been cured or waived for a period of not less than 90 consecutive days.

SECTION 18.04. Demand for Payment. If payment of the Notes is accelerated because of an Event of Default and a demand for payment is made on a Note Guarantor pursuant to Article 17, the Trustee (provided that the Trustee shall have received written notice from the Company, such Note Guarantor or a Representative identifying such Designated Senior Indebtedness, on which notice the Trustee shall be entitled to rely conclusively) shall promptly notify the holders of the Designated Senior Indebtedness of such Note Guarantor (or the Representative of such holders) of such demand. If any Designated Senior Indebtedness of such Note Guarantor is outstanding, such Note Guarantor may not pay its Guarantee until five Business Days after such holders or the Representative of the holders of the Designated Senior Indebtedness of such Note Guarantor receive notice of such demand and, thereafter, may pay its Guarantee only if this Article 18 otherwise permits payment at that time.

SECTION 18.05. When Distribution Must Be Paid Over. If a payment or distribution is made to Noteholders that because of this Article 18 should not have been made to them, the Noteholders who receive the payment or distribution shall hold such payment or distribution in trust for holders of the Senior Indebtedness of the relevant Note Guarantor and pay it over to them as their respective interests may appear.

SECTION 18.06. Subrogation. After all Senior Indebtedness of a Note Guarantor is paid in full and until the Notes are paid in full, Noteholders shall be subrogated to the rights of holders of Senior Indebtedness of such Note Guarantor to

receive distributions applicable to Designated Senior Indebtedness of such Note Guarantor. A distribution made under this Article 18 to holders of Senior Indebtedness of such Note Guarantor which otherwise would have been made to Noteholders is not, as between such Note Guarantor and Noteholders, a payment by such Note Guarantor on Senior Indebtedness of such Note Guarantor.

SECTION 18.07. Relative Rights. This Article 18 defines the relative rights of Noteholders and holders of Senior Indebtedness of a Note Guarantor. Nothing in this Indenture shall:

(a) impair, as between a Note Guarantor and Noteholders, the obligation of a Note Guarantor which is absolute and unconditional, to make payments with respect to the Guaranteed Obligations to the extent set forth in Article 17; or

(b) prevent the Trustee or any Noteholder from exercising its available remedies upon a default by a Note Guarantor under its obligations with respect to the Guaranteed Obligations, subject to the rights of holders of Senior Indebtedness of such Note Guarantor to receive distributions otherwise payable to Noteholders.

SECTION 18.08. Subordination May Not Be Impaired by a Note Guarantor. No right of any holder of Senior Indebtedness of a Note Guarantor to enforce the subordination of the obligations of such Note Guarantor hereunder shall be impaired by any act or failure to act by such Note Guarantor or by its failure to comply with this Indenture.

SECTION 18.09. Rights of Trustee and Paying Agent. Notwithstanding Section 18.03, the Trustee or the Paying Agent may continue to make payments on the Notes and shall not be charged with knowledge of the existence of facts that would prohibit the making of any such payments unless, not less than two Business Days prior to the date of such payment, a Responsible Officer of the Trustee receives written notice satisfactory to it that payments may not be made under this Article 18. A Note Guarantor, the Note Registrar or co-registrar, the Paying Agent, a Representative or a holder of Senior Indebtedness of a Note Guarantor may give the notice; provided, however, that if an issue of Senior Indebtedness of a Note Guarantor has a Representative, only the Representative may give the notice.

The Trustee in its individual or any other capacity may hold Senior Indebtedness of a Note Guarantor with the same rights it would have if it were not Trustee. The Note Registrar and co-registrar and the Paying Agent may do the same with like rights. The Trustee shall be entitled to all the rights set forth in this Article 18 with respect to any Senior Indebtedness of a Note Guarantor which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness of such Note Guarantor; and nothing in Article 8 shall deprive the Trustee of any of its rights as such holder. Nothing in this Article 18 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 8.06 or any other Section of this Indenture.

103

SECTION 18.10. Distribution or Notice to Representative. Whenever a distribution is to be made or a notice given to holders of Senior Indebtedness of a Note Guarantor, the distribution may be made and the notice given to their Representative (if any).

SECTION 18.11. Article 18 Not to Prevent Events of Default or Limit Right to Accelerate. The failure of a Note Guarantor to make a payment on any of the Guaranteed Obligations by reason of any provision in this Article 18 shall not be construed as preventing the occurrence of a default by such Note Guarantor under such obligations. Nothing in this Article 18 shall have any effect on the right of the Noteholders or the Trustee to make a demand for payment on a Note Guarantor pursuant to Article 17.

SECTION 18.12. Trustee Entitled to Rely. Upon any payment or distribution pursuant to this Article 18, the Trustee and the Noteholders shall be entitled to rely (a) upon any order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 18.02 are pending, (b) upon a certificate of the liquidating trustee or agent or other Person making such payment or distribution to the Trustee or to the Noteholders or (c) upon the Representatives for the holders of Senior Indebtedness of a Note Guarantor for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Indebtedness of a Note Guarantor and other Indebtedness of a Note Guarantor, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 18. In the event that the Trustee determines, in good faith, that evidence is required with respect to the right of any Person as a holder of Senior Indebtedness of a Note Guarantor to participate in any payment or distribution pursuant to this Article 18, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness of such Note Guarantor held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and other facts pertinent to the rights of such Person under this Article 18, 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. The provisions of Sections 8.01 and 8.02 shall be applicable to all actions or omissions of actions by the Trustee pursuant to this Article 18.

SECTION 18.13. Trustee to Effectuate Subordination. Each Noteholder by accepting a Note authorizes and directs the Trustee on his or her behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination between the Noteholders and the holders of Senior Indebtedness of each of the Note Guarantors as provided in this Article 18 and appoints the Trustee as attorney-in-fact for any and all such purposes.

SECTION 18.14. Trustee Not Fiduciary for Noteholders of Senior Indebtedness of a Note Guarantor. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness of a Note Guarantor and shall not be liable to any such holders if it shall mistakenly pay over or distribute to Noteholders or the relevant Note Guarantor or any other Person, money or assets to which any holders of Senior

104

Indebtedness of such Note Guarantor shall be entitled by virtue of this Article 18 or otherwise.

SECTION 18.15. Reliance by Noteholders of Senior Indebtedness of a Note Guarantor on Subordination Provisions. Each Noteholder by accepting a Note acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration to each holder of any Senior Indebtedness of a Note Guarantor, whether such Senior Indebtedness was created or acquired before or after the issuance of the Notes, to acquire and continue to hold, or to continue to hold, such Senior Indebtedness and such holder of Senior Indebtedness shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Indebtedness.

SECTION 18.16. Defeasance. The terms of this Article 18 shall not apply to payments from money or the proceeds of U.S. Government Obligations held in trust by the Trustee for the payment of principal of and interest, if any, on the Notes pursuant to the provisions described in Article 13.

FORM OF REVERSE OF NOTE

ON SEMICONDUCTOR CORPORATION

2.625% CONVERTIBLE SENIOR SUBORDINATED NOTES DUE 2026

This Note is one of a duly authorized issue of Notes of the Company, designated as its 2.625% Convertible Senior Subordinated Notes Due 2026 (herein called the “Notes”), unlimited in aggregate principal amount, issued and to be issued under and pursuant to an Indenture dated as of December 15, 2006 (herein called the “Indenture”), between the Company, Semiconductor Components Industries, LLC, SCG (Malaysia SMP) Holding Corporation, SCG (Czech) Holding Corporation, SCG (China) Holding Corporation, Semiconductor Components Industries Puerto Rico, Inc., Semiconductor Components Industries of Rhode Island, Inc., SCG International Development LLC and Semiconductor Components Industries International of Rhode Island, Inc., as guarantors (collectively, the “Note Guarantors”) and Deutsche Bank Trust Company Americas, as trustee (herein called the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company, the Note Guarantors and the holders of the Notes.

To guarantee the due and punctual payment of the principal and interest, including Additional Interest, if any, on the Notes and all other amounts payable by the Company under the Indenture and the Notes when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Notes and the Indenture, the Note Guarantors have, jointly and severally, unconditionally guaranteed the Guaranteed Obligations on a senior subordinated basis pursuant to the terms of the Indenture.

The Notes are subordinated in right of payment to Senior Indebtedness, as defined in the Indenture. To the extent provided in the Indenture, Senior Indebtedness must be paid before the Notes may be paid. Each of the Issuers and each Note Guarantor agrees, and each Noteholder by accepting a Note agrees, to the subordination provisions contained in the Indenture and authorizes the Trustee to give it effect and appoints the Trustee as attorney-in-fact for such purpose.

In case an Event of Default shall have occurred and be continuing, the principal and interest, including Additional Interest, if any, on all Notes may be declared by either the Trustee or the holders of not less than 25% in aggregate principal amount of the Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of at least a majority in aggregate principal amount of the Notes at the time outstanding, to execute supplemental

A-6

indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Notes; provided that no such supplemental indenture shall, without the consent of each Noteholder so affected: (a) extend the fixed maturity of any Note; (b) reduce the principal amount or premium thereof or change the date on which any Note may be redeemed pursuant to Section 3.01(a) of the Indenture; (c) reduce the rate, or extend the stated time for payment, of interest, including Additional Interest, on any Note; (d) reduce any amount payable on redemption or repurchase of the Notes; (e) change the obligation of the Company to repurchase any Note at the option of a Noteholder on a Repurchase Date in a manner adverse to the holders of Notes, or change the obligation of the Company to repurchase any Note upon the happening of a Designated Event in a manner adverse to the holders of Notes; (f) impair the right of any Noteholder to receive payment of principal and interest, including Additional Interest, if any, of such holder’s Notes on or after the due dates therefore or to institute suit for the payment thereof; (g) make the principal and interest, including Additional Interest, if any, thereof payable in any coin or currency other than that provided herein; (h) impair the right to convert the Notes or reduce the amount of consideration receivable by a Noteholder upon conversion subject to the terms set forth in the Indenture, including Section 15.06 thereof; (i) modify any of the provisions of Section 11.02 or Section 7.07 of the Indenture, except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the holder of each Note so affected; (j) change any obligation of the Company to maintain an office or agency in the places and for the purposes set forth in Section 5.02 of the Indenture; (k) reduce the quorum or voting requirements set forth in Article 10 or modify or change Article 16, 17 or 18 in any manner adverse to the Noteholders’ rights thereunder; or (l) reduce the aforesaid percentage of Notes, the holders of which are required to consent to any such amendment or supplemental indenture, without the consent of the holders of all Notes then outstanding. Subject to the provisions of the Indenture, the holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences except (A) a default in the payment interest or Additional Interest, if any, on, or the principal of, the Notes (B) a default in the payment of the Redemption Price pursuant to Article 3 of the Indenture, (C) a default in the payment of the Designated Repurchase Price or Purchase Price pursuant to Article 3 of the Indenture, or (D) a default in respect of a covenant or provisions of the Indenture which under Article 11 of the Indenture cannot be modified or amended without the consent of the holders of each or all Notes then outstanding or affected thereby. Any such consent or waiver by the holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such holder and upon all future holders and owners of this Note and any Notes which may be issued in exchange or substitution hereof, irrespective of whether or not any notation thereof is made upon this Note or such other Notes.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal and interest, including Additional Interest, if any, of this Note at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Notes are issuable in fully registered form, without coupons, in denominations of $1,000 principal amount and any multiple of $1,000. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, without payment of any service charge but with payment of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration or exchange of Notes, Notes may be exchanged for a like aggregate principal amount of Notes of any other authorized denominations.

At any time on or after December 20, 2013 and prior to maturity, the Notes may be redeemed at the option of the Company, in whole or in part, upon mailing a notice of such redemption not less than 30 days but not more than 60 days before the redemption date to the holders of Notes at their last registered addresses, all as provided in the Indenture, at a cash Redemption Price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest, including Additional Interest, if any, to, but excluding, the redemption date; provided, however, that if the redemption date falls after a Regular Record Date and on or prior to the corresponding Interest Payment Date, then interest payable on such Interest Payment Date shall be paid on such Interest Payment Date to the holders of record of such Notes on the applicable Regular Record Date instead of the holders surrendering such Notes for redemption and the Redemption Price payable will be 100% of the principal amount of such Notes and will not include any interest.

The Notes are not subject to redemption through the operation of any sinking fund.

Subject to the provisions of the Indenture, if a Noteholder elects to convert Notes in connection with a Fundamental Change that occurs prior to December 15, 2013, in which the consideration is not at least 90% common stock that is listed on or immediately after such Fundamental Change will be listed on, the New York Stock Exchange, the Nasdaq Stock Market or the American Stock Exchange, the Conversion Rate applicable to each $1,000 principal amount of Notes so converted shall be increased by an additional number of shares of Common Stock (the “Additional Shares”) as set forth in the Indenture.

If a Designated Event occurs at any time prior to maturity of the Notes, the Company shall become obligated to purchase, at the option of the holder, all or any portion of the Notes held by such holder, on a date specified by the Company that is thirty (30) days after notice thereof at a cash Designated Event Repurchase Price of 100% of the principal amount, plus accrued and unpaid interest, including

A-8

Additional Interest, if any, to, but excluding, the Designated Event Repurchase Date; provided, however, that if the Designated Event Repurchase Date falls after a Regular Record Date and on or prior to the corresponding Interest Payment Date, then interest payable on such Interest Payment Date shall be paid on such Interest Payment Date to the holders of record of such Notes on the applicable Regular Record Date instead of the holders surrendering such Notes for repurchase and the Designated Event Repurchase Price payable will be 100% of the principal amount of such Note and will not include any interest. The Notes will be subject to repurchase in multiples of $1,000 principal amount. The Company shall mail to all holders of record of the Notes a notice of the occurrence of a Designated Event and of the repurchase right arising as a result thereof on or before the 30^th day after the occurrence of such Designated Event. To exercise such right, a holder shall deliver to the Company such Note with the form entitled “Designated Event Repurchase Notice” on the reverse thereof duly completed, together with the Note, duly endorsed for transfer, on or before the close of business on the second Business Day immediately preceding the Designated Event Repurchase Date, and shall deliver the Notes to the Trustee (or other paying agent appointed by the Company) as set forth in the Indenture.

Subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase, at the option of the holder, all or any portion of the Notes held by such holder on December 15 of 2013, 2016 and 2021 in whole multiples of $1,000 at a cash Repurchase Price of 100% of the principal amount, plus accrued and unpaid interest, including Additional Interest, if any, to, but excluding, the Repurchase Date; provided, however, that if the Repurchase Date falls after a Regular Record Date and on or prior to the corresponding Interest Payment Date, then interest payable on such Interest Payment Date shall be paid on such Interest Payment Date to the holders of record of such Notes on the applicable Regular Record Date instead of the holders surrendering such Notes for repurchase and the Repurchase Price payable will be 100% of the principal amount of such Note and will not include any interest; provided further, however, that no Notes may be repurchased by the Company pursuant to this paragraph if the principal amount of the Notes has been accelerated and such acceleration has not been rescinded on or prior to the Repurchase Date. To exercise such right, a holder shall deliver to the Company such Note with the form entitled “Repurchase Notice” on the reverse thereof duly completed, together with the Note, duly endorsed for transfer, at any time from the opening of business on the date that is 20 Business Days prior to such Repurchase Date until the close of business on the date that is two Business Days prior to the Repurchase Date, and shall deliver the Notes to the Trustee (or other paying agent appointed by the Company) as set forth in the Indenture.

Holders have the right to withdraw any Designated Event Repurchase Notice or the Repurchase Notice, as the case may be, by delivering to the Trustee (or other paying agent appointed by the Company) a written notice of withdrawal up to the close of business on the Designated Event Repurchase Date or the Repurchase Date, as the case may be, all as provided in the Indenture.

A-9

If money or cash, sufficient to pay the Designated Event Repurchase Price or the Repurchase Price of all Notes or portions thereof to be purchased as of the Designated Event Repurchase Date or the Repurchase Date, as the case may be, is deposited with the Trustee (or other paying agent appointed by the Company), on the Designated Event Repurchase Date or the Repurchase Date, as the case may be, interest, and Additional Interest, will cease to accrue on such Notes (or portions thereof) immediately after such Designated Event Repurchase Date or Repurchase Date, as they case may be, and the holder thereof shall have no other rights as such other than the right to receive the repurchase price upon surrender of such Note.

Subject to the occurrence of certain events and in compliance with the provisions of the Indenture, prior to the final maturity date of the Notes, the holder hereof has the right, at its option, to convert each $1,000 principal amount of the Notes into cash and shares of the Company’s Common Stock at a Conversion Rate of 95.2381 shares (a conversion price of approximately $10.50 per share), as such shares shall be constituted at the date of conversion and subject to adjustment from time to time as provided in the Indenture, upon surrender of this Note with the form entitled “Conversion Notice” on the reverse thereof duly completed, to the Company at the office or agency of the Company maintained for that purpose in accordance with the terms of the Indenture, or at the option of such holder, the Corporate Trust Office, and, unless the shares issuable on conversion are to be issued in the same name as this Note, duly endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the holder or by his duly authorized attorney. The Company will notify the holder thereof of any event triggering the right to convert the Notes as specified above in accordance with the Indenture.

Upon conversion, a Noteholder will not receive any separate cash payment for accrued and unpaid interest and Additional Interest, if any, except as set forth below. The Company’s settlement of the Conversion Obligations as provided for in the Indenture shall be deemed to satisfy its obligation to pay the principal amount of the Notes that are converted, and accrued and unpaid interest and Additional Interest, if any, in respect of such Notes. As a result, accrued and unpaid interest and Additional Interest, if any, to, but not including, the Conversion Date shall be deemed to be paid in full rather than canceled, extinguished or forfeited. Notwithstanding the preceding sentence, if Notes are converted after the close of business on a Regular Record Date, holders of such Notes as of the close of business on the Regular Record Date will receive the interest and Additional Interest, if any, payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the opening of business on the corresponding Interest Payment Date must be accompanied by payment of an amount equal to the interest and Additional Interest, if any, payable on the Notes so converted; provided, however, that no such payment need be made (1) if the Company has specified a redemption date that is after such Regular Record Date and on or prior

A-10

to the corresponding Interest Payment Date, (2) if the Company has specified a Designated Event Repurchase Date that is after such Regular Record Date and on or prior to the corresponding Interest Payment Date or (3) to the extent of any overdue interest or Additional Interest, if any, existing at the time of conversion with respect to such Note. Except as described above, no payment or adjustment will be made for accrued interest on converted Notes.

No fractional shares will be issued upon any conversion, but an adjustment and payment in cash will be made, as provided in the Indenture, in respect of any fraction of a share which would otherwise be issuable upon the surrender of any Note or Notes for conversion. At the Company’s option, the Company may issue one share of its Common Stock in lieu of paying cash for fractional shares.

A Note in respect of which a holder is exercising its right to require repurchase upon a Designated Event or repurchase on a Repurchase Date may be converted only if such holder withdraws its election to exercise either such right in accordance with the terms of the Indenture.

Any Notes called for redemption, unless surrendered for conversion by the holders thereof on or before the close of business on the Business Day preceding the redemption date, may be deemed to be redeemed from the holders of such Notes for an amount equal to the applicable redemption price, by one or more investment banks or other purchasers who may agree with the Company (i) to purchase such Notes from the holders thereof and convert them into shares of the Company’s Common Stock and (ii) to make payment for such Notes as aforesaid to the Trustee in trust for the holders.

Upon due presentment for registration of transfer of this Note at the office or agency of the Company maintained for that purpose in accordance with the terms of the Indenture, a new Note or Notes of authorized denominations for an equal aggregate principal amount will be issued to the transferee in exchange thereof, subject to the limitations provided in the Indenture, without charge except for any tax, assessment or other governmental charge imposed in connection therewith.

The Company, the Trustee, any authenticating agent, any paying agent, any conversion agent and any Note Registrar may deem and treat the registered holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing hereon made by anyone other than the Company or any Note Registrar) for the purpose of receiving payment hereof, or on account hereof, for the conversion hereof and for all other purposes, and neither the Company nor the Trustee nor any other authenticating agent nor any paying agent nor other conversion agent nor any Note Registrar shall be affected by any notice to the contrary. All payments made to or upon the order of such registered holder shall, to the extent of the sum or sums paid, satisfy and discharge liability for monies payable on this Note.

A-11

No recourse for the payment of the principal and interest, including Additional Interest, if any, of this Note, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any supplemental indenture or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer or director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

This Note shall be deemed to be a contract made under the laws of New York, and for all purposes shall be construed in accordance with the laws of New York, without regard to conflicts of laws principles thereof.

Terms used in this Note and defined in the Indenture are used herein as therein defined.
