payment of interest becoming due on such date shall be payable to the holders of such Notes registered as such on

Repurchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date or (3) to the extent of any overdue Interest, if any, exists at the time of conversion with respect to such Note. Interest shall be

Person entitled thereto as it appears in the Note Register (or upon written notice, by wire transfer in immediately available funds, if such Person is entitled to Interest on Notes with an aggregate Principal Amount in excess of $2,000,000)
(provided that at the Stated Maturity, Interest on any Note will be payable with the Principal Amount at the Company’s office or agency in New York City) or (ii) on any Global Note by wire transfer of immediately available funds to the account
of the Depositary or its nominee. 
  
 Any Interest on any Note
which is payable, but is not punctually paid or duly provided for, on any May 1 or November 1 (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Noteholder on the relevant Regular Record Date by virtue
of its having been such Noteholder, and such Defaulted Interest shall be paid by the Company, at its election in each case, as provided in clause (1) or (2) below: 
  
 (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their
respective Predecessor Notes) are registered at 5:00 p.m., New York City time, on a “Special Record Date” for the payment of such Defaulted Interest, which shall be the date fixed in the following manner. The Company shall notify
the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment (which shall be not less than twenty-five days after the receipt by the Trustee of such notice, unless the Trustee shall
consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for
such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special
Record Date for the payment of such Defaulted Interest which shall be not more than fifteen days and not less than ten days prior to the date of the proposed payment, and not less than ten days after the receipt by the Trustee of the notice of the
proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date
therefor to be mailed, first-class postage prepaid, to each holder at his address as it appears in the Note Register, not less than ten days prior to such Special Record Date. Notice of the proposed 

  

 12 

 
payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose
names the Notes (or their respective Predecessor Notes) are registered at 5:00 p.m., New York City time, on such Special Record Date and shall no longer be payable pursuant to the following clause (2) of this Section 2.03. 
  
 (2) The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated
quotation system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
  
 Section 2.04. Execution of Notes. The Notes shall be signed in the name and on behalf of the Company by the manual or
facsimile signature of its Chief Executive Officer, President, Chief Operating Officer 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”). 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 17.12), 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.

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, 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.

 (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 (x) has notified the Company that it is unwilling or unable to continue as
Depositary for such Global Note or (y) 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 or (B) an Event of Default has occurred and is

exchange on terms acceptable to the Company, the Trustee and the Depositary, which in the case of the Trustee may include, in the Trustee’s sole discretion, among other things, the requirement that (i) the Trustee and any Note Registrar receive
(a) from the Company or the Depositary, a written order, in either case requesting such exchange, and an Opinion of Counsel (which upon receipt thereof the Trustee and such Note Registrar shall be fully protected in relying) to the effect that (x)
all securities laws in connection with such exchange have been complied with and (y) such exchange is otherwise authorized or permitted by this Indenture; and (b) from such beneficial holder (x) an affidavit as to its beneficial ownership interest
in such Global Note and/or (y) an indemnity, reasonably satisfactory to the Trustee and such Note Registrar, against any loss, liability or expense to the Trustee and such Note Registrar to the extent that the Trustee or Note Registrar acts upon
such order, affidavit and/or indemnity; and (ii) such exchange can be accomplished in a manner that is practicable and not inconsistent with the rules of any applicable Depositary or securities exchange upon which the Notes may be listed for
trading. 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) or (D) 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

Notes 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 interest 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 Trustee, as 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 interest 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 

  

 15 

 
may be, may be treated by the Company, the Subsidiary Guarantor, the Trustee and any agent of the Company, the Subsidiary Guarantor 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 Subsidiary Guarantor, the Trustee or any agent of the Company, the Subsidiary Guarantor 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 beneficial 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 Exhibit B, 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 Section 2.05(c) and 2.05(d), 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 Exhibit B, if applicable) 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 HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION. NEITHER THIS SECURITY NOR ANY INTEREST OR
PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE 

  

 16 

 
ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION. THE HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE
HEREOF: 
  
 (1) REPRESENTS THAT IT IS A
“QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT (“RULE 144A”)) AND IS PURCHASING IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT; 
  
 (2) AGREES ON ITS OWN BEHALF AND ON BEHALF OF ANY INVESTOR
ACCOUNT FOR WHICH IT HAS PURCHASED SECURITIES THAT IT WILL NOT WITHIN TWO YEARS AFTER THE ORIGINAL ISSUANCE OF THIS SECURITY OFFER, SELL OR OTHERWISE TRANSFER SUCH SECURITY OR ANY COMMON STOCK ISSUABLE UPON CONVERSION OF SUCH SECURITY EXCEPT (A) TO
RYERSON TULL, INC. (THE “ISSUER”) OR ANY SUBSIDIARY THEREOF, (B) 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, (C) TO A
QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A OR (D) PURSUANT TO THE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE); AND 
  
 (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS
SECURITY IS TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(B) OR 2(D) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. 
  
 IN CONNECTION WITH ANY TRANSFER OF THIS SECURITY WITHIN TWO YEARS AFTER THE ORIGINAL ISSUANCE OF SUCH SECURITY (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(B) ABOVE), THE
HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE TRUSTEE (OR ANY SUCCESSOR TRUSTEE, AS APPLICABLE). IF THE PROPOSED TRANSFER IS PURSUANT TO CLAUSE 2(D)
ABOVE, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE (OR ANY SUCCESSOR TRUSTEE, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THE ISSUER OR THE TRUSTEE MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH
TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THIS SECURITY PURSUANT TO CLAUSE 2(B) OR
2(D) ABOVE OR THE EXPIRATION OF TWO YEARS FROM THE ORIGINAL ISSUANCE OF THE SECURITY EVIDENCED HEREBY. 
  
 Each stock certificate representing Common Stock issued upon conversion of a Note shall bear a comparable legend as set forth in Exhibit B. 
  

 17 

 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) 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). 
  
 (e) Each Noteholder agrees to indemnify the Company and the Trustee against any liability that may result from the transfer, exchange or assignment of a
Noteholder’s Note in violation of any provision of this Indenture and/or applicable United States federal or state securities law. 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 or beneficial holders of interests 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. 
  
 Neither the Trustee nor any agent of the Trustee shall have any responsibility for actions taken or not taken by the Depositary. 
  

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. 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 satisfactory to them to save each of them harmless for any loss, claim, damage, 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 

  

 18 

 
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 Fundamental Change (and not withdrawn) or has been surrendered for repurchase on a
Repurchase Date (and not withdrawn) or is to be converted into Common Stock, cash or combination of cash and Common Stock, as the case may be, 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 satisfactory to them to save each of them harmless from any loss, claim, damage, 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 

  

 19 

 
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” or “ISIN” numbers and/or similar numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” and/or
“ISIN” numbers in notices of redemption 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 and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify
the Trustee in writing of any change in the “CUSIP” and/or similar numbers. 
  
 Section 2.10. Ranking. The indebtedness of the Company arising under or in connection with this Indenture and every outstanding Note issued under this Indenture from time to time constitutes and will constitute
a direct, unsecured and senior general obligation of the Company, ranking equally with other existing and future unsecured and senior Indebtedness of the Company and ranking senior in right of payment to existing and future Indebtedness of the
Company that is expressly made subordinate to the Notes by the terms of such Indebtedness. For purposes of this Section 2.10 only, “Indebtedness” means, without duplication, the principal or face amount of (i) all obligations for
borrowed money, (ii) all obligations evidenced by notes, notes or other similar instruments, (iii) all obligations in respect of letters of credit or bankers acceptances or similar instruments (or reimbursement obligations with respect thereto),
(iv) all obligations to pay the deferred purchase price of property or services, (v) all obligations as lessee which are capitalized in accordance with generally accepted accounting principles, and (vi) all Indebtedness of others guaranteed by the
Company or for which the Company is legally responsible or liable (whether by agreement to purchase indebtedness of, or to supply funds or to invest in, others).

 ARTICLE 3 
 REDEMPTION AND REPURCHASE OF NOTES 
  
 Section 3.01. Company’s Right to Redeem. Prior to November 5,
2009, the Notes will not be redeemable at the Company’s option. At any time on or after November 5, 2009, the Company, at its option, may redeem the Notes, in whole or in part, in accordance with the provisions of Section 3.02, Section 3.03 and
Section 3.04 on the Redemption Date for a redemption price in cash equal to 100% of the Principal Amount of the Notes to be redeemed (the “Redemption Price”), plus any accrued and unpaid Interest on the Notes redeemed to, but not
including, the Redemption Date. If the Redemption Date is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, the Interest payable on such Interest Payment Date will be paid on the Redemption Date to the holder on
the Regular Record Date. 
  
 Section 3.02. Notice of Optional
Redemption; Selection of Notes. 
  
 (a) 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 (the “Redemption Date”) and it or, at its written request received by the
Trustee not fewer than five Business Days prior (or such shorter period of time as may be acceptable to the Trustee) to the date the notice (which notice shall be prepared by the Company) of such redemption (the “Redemption Notice”)
is to be mailed, the Trustee in the name of and at the expense of the Company, shall mail or cause to be mailed the Redemption Notice not fewer than twenty calendar nor more than sixty calendar 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. Concurrently with the mailing of any such Redemption Notice,
the Company shall issue a press release announcing such redemption, the form and content of which press release shall be determined by the Company in its sole discretion. The failure to issue any such press release or any defect therein shall not
affect the validity of the Redemption Notice or any of the proceedings for the redemption of any Note called for redemption. 
  
 (b) Each such Redemption Notice shall specify: 
  
 (i) the aggregate Principal Amount of Notes to be redeemed; 
  
 (ii) the CUSIP, ISIN or similar number or numbers of the Notes being redeemed; 
  
 (iii) the Redemption Date (which shall be a Business Day);

  
 (iv) the Redemption Price at which Notes are
to be redeemed; 
  

 21 

 (v) the place or places of payment and that payment will be made upon presentation and
surrender of such Notes; 
  
 (vi) that Interest
accrued to the Redemption Date will be paid as specified in said notice, and that on and after said date Interest thereon or on the portion thereof to be redeemed will cease to accrue; 
  
 (vii) that the holder has the right to convert the Notes called for redemption; 
  
 (viii) the Conversion Rate on the date of such notice;

  
 (ix) the time and the date on which the right
to convert such Notes or portions thereof into Common Stock will expire; and 
  
 (x) that the Company will pay cash for fractional interests in shares of Common Stock, if any, as provided in this Indenture. 
  
 If fewer than all the Notes are to be redeemed, the Redemption Notice shall identify the Notes to be redeemed (including CUSIP, ISIN or similar numbers, if any). In case
any Note is to be redeemed in part only, the Redemption Notice 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. 
  
 (c) On or prior to the Redemption Date specified in the Redemption Notice given as provided in this Section 3.02, the Company will deposit with the Paying Agent (or, if the Company or the Subsidiary Guarantor is
acting as 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 into Common Stock) at the Redemption Price plus accrued and unpaid interest to, but excluding, the Redemption Date; provided that if such payment is made on the Redemption Date, it must
be received by the Paying Agent by 10:00 a.m., New York City time, on such date. The Company shall be entitled to retain any interest, yield or gain on amounts deposited with the Paying Agent pursuant to this Section 3.02(c) in excess of amounts
required hereunder to pay the Redemption Price and accrued interest to, but not including, the Redemption Date. Subject to the last sentence of Section 8.05, if any Note called for redemption is converted pursuant hereto prior to such Redemption
Date, any money deposited with the 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 or the Subsidiary Guarantor, 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 thirty 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. 
  
 (d)
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 

  

 22 

 
redeemed (in Principal Amounts of $1,000 or integral 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 from the portion 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 Redemption Notice.

  
 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 days next preceding the mailing of a Redemption Notice 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 into Common Stock pursuant to the
terms hereof, become due and payable on the Redemption Date and at the place or places stated in such notice at the Redemption Price plus interest accrued to, but not including, the Redemption Date. Interest on the Notes or portion of Notes so
called for redemption shall cease to accrue on and after the Redemption Date (unless the Company shall default in the payment of the Redemption Price plus interest accrued to, but not including, the Redemption Date) and after 5:00 p.m., New York
City time, on the second Trading Day immediately preceding the Redemption Date, such Notes shall cease to be convertible into Common Stock and, except as provided in Section 8.05, 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 plus interest accrued to, but not including, the Redemption Date. 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 Redemption Price plus interest accrued to, but not including, the Redemption Date; provided that if the applicable Redemption
Date is after the applicable Regular Record Date and on or before an Interest Payment Date, the 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 on such date. 
  
 (a) 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. 
  
 Notwithstanding the foregoing, the Trustee shall not redeem any Notes or mail any Redemption Notice during the continuance
of a default in payment of Interest on the Notes. If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid or duly provided for, continue to bear interest at the rate borne by the
Note, compounded semi-annually, and such Note shall remain convertible into cash or a 

  

 23 

 
combination of cash and Common Stock, as the case may be, until the Principal Amount and Interest shall have been paid or duly provided for. The Company will
notify all of the holders if the Company redeems any of the Notes. 
  
 Section 3.04. [Reserved]. 
  
 Section 3.05.
Repurchase of Notes by the Company at Option of Holders upon a Fundamental Change. 
  
 (a) If a Fundamental Change shall occur at any time prior to Stated Maturity, each holder shall have the right, at such holder’s option, to require the Company to repurchase for cash all or a portion of such
holder’s Notes, or any portion of the Principal Amount thereof that is equal to $1,000 or an integral multiple of $1,000, on the date specified in the Fundamental Change Repurchase Notice, which date shall be no more than thirty calendar days
after the date of the Fundamental Change Repurchase Notice (subject to extension to comply with applicable law) (the “Fundamental Change Repurchase Date”). The Company shall repurchase such Notes at a price equal to 100% of the
Principal Amount thereof (the “Fundamental Change Repurchase Price”) plus any accrued and unpaid Interest on the Notes to, but not including, the Fundamental Change Repurchase Date. If the applicable Fundamental Change Repurchase
Date is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, the 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
record date instead of the holders surrendering such Notes for repurchase on such date. 
  
 (b) On or before the thirtieth calendar day after the occurrence of a Fundamental Change, the Company, or at its written request the Trustee in the name of and at the expense of the Company (which request must be
received by the Trustee at least five Business Days prior to the date the Trustee is requested to give notice as described below, unless the Trustee shall agree to a shorter period), shall mail or cause to be mailed, by first class mail, to all
holders of record on such date a notice (which notice shall be prepared by the Company) (the “Fundamental Change Repurchase Notice”) of the occurrence of such Fundamental Change and of the repurchase right at the option of the
holders arising as a result thereof to each holder of Notes at its last address as the same appears on the Note Register, and to beneficial owners as required by applicable law; provided that if the Company shall give such notice, it shall
also give written notice of the Fundamental Change to the Trustee and Paying Agent, if other than the Trustee, at such time as it is mailed to Noteholders. Such 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. Each Fundamental Change Repurchase Notice shall state, among other things: 
  
 (i) the events causing the Fundamental Change; 
  

(ii) the date of the Fundamental Change; 
  
 (iii) the last date on which a holder may exercise the repurchase right; 
  
 (iv) the Fundamental Change Repurchase Price and, to the extent known at the time of such notice, the amount
of Interest that will be payable with respect to the Notes to, but not including, the Fundamental Change Repurchase Date; 
  

 24 

 (v) the Fundamental Change Repurchase Date; 
  
 (vi) the name and address of the Paying Agent and the
Conversion Agent, if the Notes are then convertible in accordance with Section 15.01; 
  
 (vii) if the Notes are then convertible in accordance with Section 15.01, the applicable Conversion Rate at the time of such notice (and
any applicable adjustments to the applicable Conversion Rate); 
  
 (viii) if the Notes are then convertible in accordance with Section 15.01, that Notes as to which a Fundamental Change Repurchase Election has been given by the holder may be converted only if the election has been
withdrawn by the holder in accordance with the terms of this Indenture; 
  
 (ix) that the holder shall have the right to withdraw any Notes surrendered prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change Repurchase Date (or any such later
time as may be required by applicable law); 
  
 (x) a description of the procedures which a Noteholder must follow to exercise such repurchase right or to withdraw any surrendered Notes; 
  
 (xi) the CUSIP, ISIN or similar number or numbers of the Notes (if then generally in use); and 
  
 (xii) briefly, the conversion rights of the holders of the
Notes. 
  
 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) Notes shall be repurchased pursuant to this Section 3.05 at the option of the holder upon: 
  
 (i) delivery to the Paying Agent by a holder of a duly
completed notice (a “Fundamental Change Repurchase Election”) in the form set forth on the reverse of the Note at any time prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change
Repurchase Date, which is subject to extension to comply with applicable law, stating: 
  
 (A) if certificated notes have been issued, the certificate numbers of the Notes which the holder shall deliver to be repurchased;

  
 (B) the portion of the Principal Amount of
the Notes that the holder shall deliver to be repurchased, which portion must be $1,000 or an integral multiple thereof; and 
  

 25 

 (C) that such Notes shall be repurchased by the Company as of the Fundamental Change
Repurchase Date pursuant to the terms and conditions specified in the Notes and in the Indenture; and 
  
 (ii) delivery or book-entry transfer of the Notes to the Paying Agent simultaneously with or at any time after delivery of the Fundamental
Change Repurchase Election (together with all necessary endorsements) at the Corporate Trust Office of the Paying Agent, such delivery or transfer being a condition to receipt by the holder of the Fundamental Change Repurchase Price therefor;
provided that such Fundamental Change Repurchase Price shall be so paid pursuant to this Section 3.05 only if the Notes so delivered or transferred to the Paying Agent shall conform in all respects to the description thereof in the related
Fundamental Change Repurchase Election. All questions as to the validity, eligibility (including time of receipt) and acceptance of any Note for repurchase shall be determined by the Company, whose determination shall be final and binding absent
manifest error. 
  
 If the Notes are not in certificated form,

 (x) briefly, the conversion rights of the holders of the Notes. 
  
 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 3.06. 
  
 (c) Notes shall be repurchased pursuant to this Section 3.06 at the option of the holder upon: 
  
 (i) delivery to the Paying Agent by a holder of a duly completed notice (a “Company Repurchase Election”) in the form set
forth on the reverse of the Note at any time from 9:00 a.m., New York City time, on the 20th Business Day preceding

to the Paying Agent shall conform in all respects to the description thereof in the related Company Repurchase Election. All questions as to the validity, eligibility (including time of receipt) and acceptance of any Note for repurchase shall be
determined by the Company, whose determination shall be final and binding absent manifest error.

 Section 3.07. [Reserved]. 
  
 Section 3.08. Conditions and Procedures for Repurchase at Option of
Holders. 
  
 (a) At the request of the holder, the Company
shall repurchase from such holder, pursuant to Section 3.05 or Section 3.06, 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 repurchase of all of a
Note also apply to the repurchase of such portion of such Note. Upon presentation of any Note repurchased 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 any authorized denomination, in aggregate Principal Amount equal to the portion of the Notes presented not repurchased. 
  
 (b) On or prior to a Repurchase Date, the Company will deposit with the Paying Agent (or, if the Company or the Subsidiary
Guarantor is acting as the Paying Agent, set aside, segregate and hold in trust as provided in Section 5.04) an amount of money sufficient to repurchase on the Repurchase Date all the Notes or portions thereof to be repurchased on such date at the
Repurchase Price plus accrued and unpaid Interest, if any, to, but not including, the Repurchase Date, if applicable; provided that if such deposit is made on the 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. 
  
 If on
the Repurchase Date the Trustee or other Paying Agent appointed by the Company (or, if the Company or the Subsidiary Guarantor is acting as the Paying Agent, it or the Subsidiary Guarantor) holds money sufficient to pay the aggregate Repurchase
Price of all the Notes or portions thereof that are to be repurchased plus accrued and unpaid Interest, if any, to, 

  

 28 

 
but not including, the Repurchase Date, if applicable, then, on such Repurchase Date (i) such Notes will cease to be outstanding, (ii) Interest on such Notes
will cease to accrue, and (iii) all other rights of the holders of such Notes will terminate (other than the right to receive the Repurchase Price plus accrued and unpaid Interest, if any, to, but not including, the Repurchase Date, if applicable
upon book-entry transfer or delivery of the Notes, as the case may be). 
  
 (c) Upon receipt by the Paying Agent of a Repurchase Election, the holder of the Note in respect of which such Repurchase Election was given shall (unless such Repurchase Election is validly withdrawn) thereafter be entitled to receive
solely the Repurchase Price with respect to such Note plus accrued and unpaid Interest, if any, to, but not including, the Repurchase Date, if applicable. Such Repurchase Price plus accrued and unpaid Interest, if any, to, but not including, the
Repurchase Date, if applicable, shall be paid to such holder, subject to receipt of funds and/or Notes by the Paying Agent, promptly following the later of (x) the Repurchase Date with respect to such Note (provided the holder has satisfied the
conditions in Section 3.05(c) or Section 3.06(c), as applicable) and (y) the time of book-entry transfer or delivery of such Note to the Paying Agent by the holder thereof in the manner required by Section 3.05(c) or Section 3.06(c), as applicable.
Notes in respect of which a Repurchase Election 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 Election unless such Repurchase Election has first been
validly withdrawn. 
  
 (d) Notwithstanding anything herein to the
contrary, any holder delivering to the Paying Agent a Repurchase Election shall have the right to withdraw such Repurchase Election, in whole or in part, at any time prior to 5:00 p.m., New York City time, on the Business Day preceding the
Repurchase Date (or any such later time as may be required by applicable law) by delivery of a written notice of withdrawal to the Paying Agent, specifying: 
  
 (i) if certificated Notes have been issued, the certificate numbers of the withdrawn Notes; 
  
 (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 Repurchase Election and which has been or will be delivered for repurchase by the Company. 
  
 If the Notes are not in certificated form, holders must provide notice of their withdrawal in accordance with the
appropriate procedures of the Depositary. 
  
 The Paying Agent
shall promptly notify the Company of the receipt by it of any Repurchase Election or written notice of withdrawal thereof. 
  
 (e) The Company will comply with the provisions of Rule 13e-4 and any other tender offer rules under the Exchange Act to the extent then applicable in
connection with the repurchase rights of the holders of Notes in the event of a Fundamental Change or on any Company Repurchase Date. If then required by applicable rules, the Company will file a 

  

 29 

 
Schedule TO or any other schedule required in connection with any offer by the Company to repurchase Notes. 
  
 (f) There shall be no repurchase of any Notes pursuant to Section 3.05 or
Section 3.06 if there has occurred at any time prior to, and is continuing on, the Repurchase Date an Event of Default (other than an Event of Default that is cured by the payment of the Repurchase Price with respect to such Notes). The Paying Agent
will promptly return to the respective holders thereof any Notes (x) with respect to which a Repurchase Election has been withdrawn in compliance with this Indenture or (y) held by it during the continuance of an Event of Default (other than a
default in the payment of the Repurchase Price with respect to such Notes) in which case, upon such return, the Repurchase Election with respect thereto shall be deemed to have been withdrawn. 
  
 (g) The Paying Agent shall return to the Company any cash that remains
unclaimed as provided in Section 13.03, together with interest, if any, thereon, held by them for the payment of the Repurchase Price; provided that to the extent that the aggregate amount of cash deposited by the Company pursuant to Section
3.08(b) exceeds the aggregate Repurchase Price of the Notes or portions thereof which the Company is obligated to purchase as of the Repurchase Date then, unless otherwise agreed in writing with the Company, promptly after the Business Day following
the Repurchase Date, the Paying Agent shall return any such excess to the Company together with interest, if any, thereon. 
  
 (h) In the case of a reclassification, change, consolidation, merger, binding share exchange, 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 cash, securities or other property, 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 cash, securities or other property (as determined by the Company, which determination shall be conclusive and binding), 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 Fundamental
Change, including without limitation the applicable provisions of this Article 3 and the definition of Fundamental Change, 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 (in lieu of the Company).

 (1) that it will hold all sums held by it as such agent for the payment of the Principal Amount of or Interest on the Notes (whether such
sums have been paid to it by the Company or by any other obligor on the Notes) in trust for the benefit of the holders of the Notes; 
  

 31 

 (2) that it will give the Trustee notice of any failure by the Company (or by any other
obligor on the Notes) to make any payment of the Principal Amount of or Interest on the Notes when the same shall be due and payable; and 
  
 (3) that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all
sums so held in trust. 
  
 The Company shall, on or before each
due date of the Principal Amount of or Interest on the Notes, deposit with the Paying Agent a sum (in funds which are immediately available on the due date for such payment) sufficient to pay such Principal Amount or Interest, and (unless such
Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided that if such deposit is made on the due date, such deposit shall be received by the Paying Agent by 10:00 a.m., New York
City time, on such date.

Amount or Interest so becoming due and will promptly notify the Trustee of any failure to take such action and of any failure by the Company (or any other obligor under the Notes) to make any payment of the Principal Amount of or Interest on the
Notes when the same shall become due and payable.

by the Company, the Subsidiary Guarantor or any Paying Agent hereunder as required by this Section 5.04, such sums to be held by the Trustee upon the trusts herein contained and upon such payment by the Company, the Subsidiary Guarantor or any
Paying Agent to the Trustee, the Company, the Subsidiary Guarantor or such Paying Agent shall be released from all further liability with respect to such sums.

 Section 5.05. Existence. Subject to Article 12, the Company will do or
cause to be done all things necessary to preserve and keep in full force and effect its existence and rights (charter and statutory); provided that the Company shall not be required to preserve any such right if the Company shall determine that the

prospective purchaser of Notes or such Common Stock designated by such holder or beneficial holder, the information required pursuant to Rule 144A(d)(4) under the Securities Act upon the request of any holder or beneficial holder of the Notes or
such Common Stock and it will take such further action as any holder or beneficial holder of such Notes or such Common Stock may reasonably request, all to the extent required from time to time to enable such holder or beneficial holder to sell its
Notes or Common Stock without registration under the Securities Act within the limitation of the exemption provided by Rule 144A, as such Rule may be amended from time to time. Upon the request of any holder or any beneficial holder of the Notes or
such Common Stock, the Company will deliver to such holder a written statement as to whether it has complied with such requirements. 
  
 Section 5.07. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist
upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the Principal Amount of or Interest on
the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture and the Company (to the extent it may lawfully do so) hereby expressly waives all
benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though
no such law had been enacted.

and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and the nature
and the status thereof of which the signer may have knowledge.

the Trustee at its Corporate Trust Office.

Notice”) to the Trustee of its obligation to pay Additional Interest no later than fifteen calendar days prior to the proposed payment date for the Additional Interest, and the Additional Interest Notice shall set forth the amount of
Additional Interest to be paid by the Company on such payment date. The Trustee shall not at any time be under any duty or responsibility to any holder of Notes to determine the Additional Interest, or with respect to the nature, extent or
calculation of the amount of Additional Interest when made, or with respect to the method employed in such calculation of the Additional Interest.

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 the Principal Amount of all the Notes and the Interest accrued and unpaid thereon 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(h) or Section 7.01(i) occurs, the Principal Amount of all the Notes and the Interest accrued and unpaid thereon shall be immediately and automatically due and payable without necessity of further action. If, however, at any time after
the Principal Amount 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, (a) the Company shall pay or shall
deposit with the Trustee a sum sufficient to pay (i) all matured installments of Interest upon all Notes, (ii) the Principal Amount of any and all Notes which shall have become due otherwise than by acceleration, (iii) interest on overdue
installments of Interest (to the extent that payment of such interest is enforceable under applicable law) and on such Principal Amount at the rate borne by the Notes, to the date of such payment or deposit and (iv) amounts due to the Trustee
pursuant to Section 8.06, and (b) any and all defaults under this Indenture, other than the nonpayment of Principal Amount of and accrued and unpaid Interest on Notes 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 on behalf of the holders of all 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 subject to Section 7.07; 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. The Company shall notify in writing a Responsible Officer of the Trustee, promptly upon becoming aware thereof, of any Event of Default, as provided in Section 5.08. 
  
 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 covenants that in the case
of an Event of Default pursuant to Section 7.01(a) or 7.01(b), then, upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the holders of the Notes, (i) the whole amount that then shall have become due and payable on
all such Notes for Principal Amount or Interest, as the case may be, with interest upon the overdue Principal Amount and (to the extent that payment of such interest is enforceable under applicable law) upon the overdue installments of Interest at
the rate borne by the Notes, from the required payment date, and (ii) in addition thereto, any amounts due the Trustee under Section 8.06. Until such demand by the Trustee, the Company may pay the Principal Amount of and Interest on the Notes to the
registered holders, whether or not the Notes are overdue. 
  
 In
case the Company 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 or any other obligor on the Notes and collect in the manner
provided by law out of the property of the Company 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 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 or such
other obligor, the property of the Company or such other obligor, or in the case of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor,
the Trustee, irrespective of whether the Principal Amount 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 the Principal Amount 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 

  

 38 

 
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 or other property collected by the Trustee pursuant to this Article 7, or any monies or other property otherwise distributable in respect of the Company’s obligations under this Indenture, 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 (including any
predecessor Trustee) under Section 8.06; 
  
 SECOND: In case the
Principal Amount of the outstanding Notes shall not have become due and be unpaid, to the payment of Interest on the Notes in default in the order of the maturity of the installments of such Interest, with interest (to the extent that such interest
has been collected by the Trustee) as provided in Section 7.02 upon the overdue installments of Interest at the rate borne by the Notes, such payments to be made ratably to the Persons entitled thereto; 
  
 THIRD: In case the Principal Amount of the outstanding Notes shall have
become due, by declaration or otherwise, and be unpaid, to the payment of the whole amount then owing and unpaid upon the Notes for Principal Amount and Interest, with interest on the overdue Principal Amount and (to the extent that such interest
has been collected by the Trustee) upon overdue installments of Interest, at the rate borne by 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 Amount and Interest without preference or priority of the Principal Amount over Interest, or of Interest over the Principal Amount, 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 Amount and accrued and unpaid Interest; and 
  
 FOURTH: To the payment of the remainder, if any, to the Company or any other Person lawfully entitled thereto.

 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 (a) such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, (b) the holders of not less than 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 security or
indemnity satisfactory to the Trustee as it may require against the costs, expenses and liabilities to be incurred therein or thereby, (c) the Trustee for sixty calendar 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 (d) 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 Amount of (including any Redemption Price or Repurchase Price pursuant to Article 3) and accrued Interest on
such Note on or after the respective due dates expressed in such Note, 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 contained 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, in 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 

  

 40 

 
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 Waiver 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 Noteholders 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 on,
or the Principal Amount of, the Notes, (ii) a failure by the Company to convert any Notes into cash or a combination of cash and Common Stock, as the case may be, (iii) a default in the payment of the Redemption Price pursuant to Section 3.03, (iv)
a default in the payment of the Fundamental Change Repurchase Price pursuant to Section 3.05 or Company Repurchase Price pursuant to Section 3.06 or (v) a default in respect of a covenant or provision 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 ninety calendar days after a Responsible Officer of the Trustee has actual knowledge of the occurrence of a default, 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 Amount of or Interest 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. For the purpose of this Section 7.08, the term “default” 

  

 41 

 
means any event which is, or after notice or lapse of time or both would become, an Event of Default. 
  
 Section 7.09. Undertaking to Pay Costs. All parties to this Indenture
agree, and each holder of any Note by its 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 ten percent 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 Amount of or Interest 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 such person’s own affairs. 
  
 No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: 
  
 (a) prior to the occurrence of an Event of Default and after the curing or
waiving of all Events of Default which may have occurred: 
  
 (i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture and the Trust Indenture Act, and the Trustee shall not be liable except for the performance of such
duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture and the Trust Indenture Act against the Trustee; and 
  
 (ii) in the absence of bad faith 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 

  

 42 

 
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; 
  
 (d) the Trustee shall not be liable in
respect of any payment (as to the correctness of amount, entitlement to receive or any other matters relating to payment) or notice effected by the Company, the Subsidiary Guarantor or any Paying Agent or any records maintained by any co-registrar
with respect to the Notes; and 
  
 (e) 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.

  
 (f) The Trustee shall not be deemed to have knowledge or
notice of any default (as defined in Section 7.08) or Event of Default hereunder unless a Responsible Officer of the Trustee shall have received at the Corporate Trust Office written notice of such default or Event of Default from the Company or the
holders of at least 10% in aggregate Principal Amount of the Notes and such notice refers to such default or Event of Default, the Notes and the Indenture. 
  
 None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any liability in the
performance of any of its duties 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 assured to it. 

 
 Whether or not therein provided, every provision of this Indenture
relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section 8.01. 
  
 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, 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; 
  

 43 

 (b) any request, direction, order or demand of the Company or the Subsidiary Guarantor mentioned herein
shall be sufficiently evidenced by an Officers’ Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to the Trustee by a copy thereof certified
by the Secretary or an Assistant Secretary of the Company; 
  
 (c)
the Trustee may consult with counsel of its own selection and any advice or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in accordance with
such advice or Opinion of Counsel; 
  
 (d) the Trustee shall be
under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Noteholders pursuant to the provisions of this Indenture, unless such Noteholders shall have offered to the
Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby; 
  
 (e) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, note 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 and the Subsidiary Guarantor, personally or by agent or attorney at the sole cost of the Company and shall incur no liability
or additional liability of any kind by reason of such inquiry or investigation; 
  
 (f) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed by it with due care hereunder; 
  
 (g) the Trustee shall not be liable for any action taken, suffered or omitted to be taken by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon
it by this Indenture; 
  
 (h) in no event shall the Trustee be
responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and
regardless of the form of action; 
  
 (i) the rights, privileges,
protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other
Person employed to act hereunder; 
  
 (j) the Trustee may request
that the Company and the Subsidiary Guarantor, respectively deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which

  

 44 

 
Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in
any such certificate previously delivered and not superseded; and 
  
 (k) before the Trustee acts or refrains from acting, it shall require an Officers’ Certificate or an Opinion of Counsel. The Trustee shall not be liable for any action which it takes or omits to take in good faith in reliance on the
Officers’ Certificate or Opinion of Counsel. 
  
 Section
8.03. No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication) and the Subsidiary Guarantee shall be taken as the statements of the Company and the
Subsidiary Guarantor, respectively, 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, Bid Solicitation Agents, Conversion
Agents or Registrar May Own Notes. The Trustee, any Paying Agent, any Bid Solicitation 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, Bid Solicitation Agent, Conversion Agent or Note Registrar. 
  
 Section 8.05. Monies to Be Held in Trust. Subject to the provisions of Section 13.03, 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.

receive, 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 incurred or made by the Trustee in accordance with any of the provisions of this

or bad faith. The Company and the Subsidiary Guarantor, jointly and severally, also covenant 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, willful misconduct
or bad faith 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 

  

 45 

 
trust or in any other capacity hereunder, including the costs and expenses (including reasonable attorneys’ fees and expenses) of defending themselves
against any claim (whether asserted by the Company, the Subsidiary Guarantor, any holder or any other Person) of liability in connection with the exercise or performance of any of its powers or duties hereunder. The respective obligations of the
Company and the Subsidiary Guarantor under this Section 8.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses (including reasonable attorneys’ fees and 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 Subsidiary
Guarantor under this Section shall survive the resignation or removal of the Trustee and the satisfaction and discharge or termination of this Indenture. 
  
 When the Trustee and its agents and any authenticating agent incur expenses or render services after an Event of Default specified in Section 7.01(h) or
Section 7.01(i) with respect to the Company occurs, the expenses (including reasonable attorneys’ fees and 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 either eliminate such interest or resign, to the extent and in the manner
provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. 
  
 Section 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 $50,000,000 (or if such Person is a member of a bank holding company system, its bank holding company shall have a combined capital and surplus of at least $50,000,000). If such Person publishes reports of condition at least
annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 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 

  

 46 

 
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 calendar days after the mailing of such notice of resignation to the Noteholders, the resigning Trustee may, upon ten 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 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 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 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 calendar 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 calendar 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(a)
provided, may petition any court of competent jurisdiction for an appointment of a successor trustee. 
  

 47 

 (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. 
  
 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 and the expense 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) calendar 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 Merger. Any Person into
which the Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any Person 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 Person succeeding to all or substantially all of the corporate trust business of the Trustee, such Person 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 

  

 48 

 
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). 
  
 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 calendar 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 Subsidiary Guarantor, 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 Amount of and Interest on such Note, for conversion of such Note and for all
other purposes; and none of the Company, the Subsidiary Guarantor, the Trustee, any Paying 

  

 49 

 
Agent, any Conversion Agent or 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 actually 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 Holders 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.

satisfactory in form to the Trustee, of the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be
performed or satisfied by the Subsidiary Guarantor and by supplemental agreement, executed and delivered to the Trustee and reasonably satisfactory in form to the Trustee, of all of the obligations of the Subsidiary Guarantor under the Registration
Rights Agreement, such successor Person shall succeed to and be substituted for the Subsidiary Guarantor, with the same effect as if it had been named herein as the Subsidiary Guarantor as of the date of this Indenture. Such successor Person
thereupon may cause to be signed, and may issue either in its own name or in the name of the Subsidiary Guarantor any or all of the Subsidiary Guarantees of the Subsidiary Guarantor, issuable hereunder that theretofore shall not have been signed by
the Subsidiary Guarantor and delivered to the Trustee. All the Subsidiary Guarantees of the Subsidiary Guarantor so issued shall in all respects have the same legal rank and benefit under this Indenture as the Subsidiary Guarantee of the Subsidiary
Guarantor theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Subsidiary Guarantees had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale,
conveyance or transfer (but not in the case of a lease), the applicable Person named as a “Subsidiary Guarantor” 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 Subsidiary Guarantees and from its obligations under this Indenture and
its Subsidiary Guarantee. 
  
 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 12.03. Opinion of Counsel to Be Given Trustee. The Trustee shall receive an Officers’ Certificate and an
Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption complies with the provisions of this Article 12. 
  
 ARTICLE 13 
 SATISFACTION AND DISCHARGE OF INDENTURE 
  
 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 and the Company shall deposit with the Paying Agent (or, if the Company or the Subsidiary Guarantor is acting as Paying Agent, set aside, segregate and hold in trust as
provided in Section 5.04), in trust, funds sufficient to pay all amounts due and owing on 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, and if in either case 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 

  

 58 

 
Amount of and Interest 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, including those pursuant to Section 8.06), and the Trustee, on written demand of the Company accompanied by an Officers’ Certificate and an
Opinion of Counsel as required by Section 17.05 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. 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 13.03. 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 Amount of or Interest on Notes and not
applied but remaining unclaimed by the holders of Notes for two years after the date upon which the Principal Amount of or Interest on such Notes, as the case may be, shall have become due and payable, shall be repaid to the Company by the Trustee
on written 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. 
  
 ARTICLE 14 
 IMMUNITY OF INCORPORATORS, STOCKHOLDERS,
OFFICERS AND DIRECTORS 
  
 Section 14.01. Indenture and Notes Solely Corporate Obligations. No recourse for the payment of the Principal Amount of or Interest on any Note, or for any claim based thereon or otherwise in respect thereof, and no recourse under or
upon any obligation, covenant or agreement of the Company or the Subsidiary Guarantor in this Indenture or in any supplemental indenture or in any Note, or of the Subsidiary Guarantor under the Subsidiary Guarantee or because of the creation of any
indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer, director or subsidiary, as such, past, present or future, of the Company or the Subsidiary Guarantor or of any successor corporation,
either directly or through the Company or the Subsidiary Guarantor 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; it being expressly
understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issue of the Notes.

 ARTICLE 15 
 CONVERSION OF NOTES 
  
 Section 15.01. Right to Convert. (a) Subject to and upon compliance with the provisions of this Indenture, at any time prior to 5:00 p.m., New York
City time, on the Trading Day immediately preceding the Stated Maturity, the holder of any Note shall have the right, at such holder’s option, to convert each $1,000 Principal Amount of the Notes and integral multiples thereof, into cash or a
combination of cash and fully paid and non-assessable shares of Common Stock (as such shares shall then be constituted) at the Conversion Rate in effect at such time, subject to Section 15.01(d), 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. The Notes shall be convertible only during the following periods upon the occurrence of one of the
following events: 
  
 (i) (A) during any calendar
quarter (and only during such calendar quarter) commencing after December 31, 2004 and before January 1, 2020, if the Last Reported Sale Price of the Common Stock for at least twenty Trading Days during the period of thirty consecutive Trading Days
ending on the last Trading Day of the preceding calendar quarter is greater than or equal to 125% of the applicable Conversion Price on such last Trading Day or (B) at any time on or after January 1, 2020 if the Last Reported Sale Price of the
Common Stock on any date on or after December 31, 2019 is greater than or equal to 125% of the applicable Conversion Price; 
  
 (ii) during the five Business Day period after any five consecutive Trading Day period in which the Trading Price per Note, as determined
following a request by a holder in accordance with the procedures described below, for each day of that period is less than 98% of the product of the applicable Conversion Rate and the Last Reported Sale Price of the Common Stock for each day during
such period; 
  
 (iii) in the event that the
Company calls any or all of the Notes for redemption, at any time prior to 5:00 p.m., New York City time, on the second Trading Day immediately preceding the Redemption Date at which time the right to convert such Notes will expire, unless the
Company fails to pay the Redemption Price; provided that only those Notes that are called for redemption may be converted following such an event; or 
  
 (iv) as provided in Section (b) of this Section 15.01. 
  
 (b) In addition, if: 
  
 (i) (A) the Company distributes to all holders of Common Stock rights or warrants entitling them to subscribe for or purchase (for a
period expiring within 45 calendar days of the date of the distribution) shares of Common Stock at less than the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the declaration date of the distribution, or (B)
the Company distributes to all holders of Common Stock, assets, debt securities or rights to purchase securities of the Company, which distribution has a per share value as determined by the Board of 

  

 60 

 
Directors and set forth in a Board Resolution exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the
declaration date for such distribution, 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 Business
Days prior to the Ex-Dividend Date for such distribution, until the earlier of 5:00 p.m., New York City time, on the Business Day immediately preceding, but not including, the Ex-Dividend Date or the date the Company publicly announces that such
distribution will not take place; provided that no holder may convert Notes in accordance with this Section 15.01(b)(i) if the holder will otherwise participate in such distribution without conversion as a result of holding the Notes;

  
 (ii) the Company consolidates with or merges
with or into another Person, is a party to a binding share exchange or conveys, transfers, sells, leases or otherwise disposes of all or substantially all of its assets, in each case pursuant to which the Common Stock would be converted into (A)
cash or property other than securities, or (B) cash, securities or other property, provided that in the case of clause (B), such transaction also constitutes a Fundamental Change, then the Notes may be surrendered for conversion at any time
beginning fifteen calendar days prior to the anticipated effective date of the transaction until and including the date which is fifteen calendar days after the actual effective date (“Effective Date”) of the transaction (or if such
consolidation, merger, share exchange or transfer also constitutes a Fundamental Change, until the Fundamental Change Repurchase Date corresponding to such Fundamental Change). The Board of Directors shall determine the anticipated Effective Date of
the transaction, and such determination shall be conclusive and binding on the holders and shall be publicly announced by the Company by publication on its Web site or through such other public medium as it may use at that time not later than two
Business Days prior to such 15th calendar day; 
  
 (c) Whenever
the Notes shall become convertible pursuant to this Section 15.01, the Company or, at the Company’s request, the Trustee in the name and at the expense of the Company, shall notify the holders of the event triggering such convertibility in the
manner provided in Section 17.03, and the Company shall also publicly announce such information by publication on the Company’s Web site or through such other public medium as it may use at such time. Any notice so given shall be conclusively
presumed to have been duly given, whether or not the holder receives such notice. 
  
 In connection with any conversion pursuant to Section 15.01(a)(ii), the Bid Solicitation Agent shall have no obligation to obtain the bids necessary for the Company to determine the Trading Price per Note unless the
Company has requested it to do so, and the Company shall have no obligation to make such request unless so requested by a holder. At such time, the Company will instruct the Bid Solicitation Agent to obtain the bids so that the Company can determine
the Trading Price per Note beginning on the next Trading Day and on each successive Trading Day until the Trading Price per Note is greater than or equal to 98% of the product of the Conversion Rate and the Last Reported Sale Price of the Common
Stock. 
  

 61 

 The Company or its designated agent shall determine on a daily basis during the last ten Trading Days of
each calendar quarter (until such day, if any, as the Notes are determined to be convertible) whether the Notes shall be convertible as a result of the occurrence of an event specified in Section 15.01(a)(i) and, if the Notes shall be so
convertible, the Company shall promptly deliver to the Conversion Agent written notice thereof. 
  
 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, 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; provided,
however, that nothing herein shall be construed to relieve the Trustee of its duties pursuant to Section 15.01 hereof. 
  
 (d) A Note in respect of which a holder is electing to exercise its option to require repurchase upon a Fundamental Change pursuant to Section 3.05 or
repurchase pursuant to Section 3.06 may be converted only if such holder withdraws its election in accordance with Section 3.08(d). 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 to Common Stock under this Article 15. 
  
 (e) If a Noteholder elects to convert its notes in connection with a specified corporate transaction pursuant to Section 15.01(b) that occurs prior to
November 1, 2009, and the corporate transaction also constitutes a Fundamental Change, such Noteholder will be entitled to receive, in addition to the cash or combination of cash and shares of Common Stock, as the case may be, equal to the
Conversion Rate per $1,000 Principal Amount of Notes, an additional number of shares of Common Stock (the “Additional Shares”) as described below, provided that if the Stock Price is greater than $65.00 or less than $14.74
(subject in each case to adjustment as described below), the number of Additional Shares shall be zero. 
  
 The number of Additional Shares will be determined by reference to the table attached as Schedule A hereto, based on the Effective Date and the Stock
Price; provided that if the Stock Price is between two Stock Price amounts in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares will be determined by a straight-line interpolation
between the number of Additional Shares set forth for the higher and lower Stock Price amounts and the two dates, as applicable, based on a 365-day year. 
  
 The Stock Prices set forth in the first row of the table in Schedule A hereto and set forth in the first paragraph of this Section 15.01(e) will be
adjusted as of any date on which the Conversion Rate of the Notes is adjusted. The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion
Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares will be adjusted in the same manner as the Conversion Rate as set
forth Section 15.05. 
  

 62 

 Notwithstanding the foregoing, in no event will the total number of shares of Common Stock issuable upon
conversion exceed 67.8426 per $1,000 Principal Amount of Notes, subject to adjustments in the same manner as the Conversion Rate as set forth in Section 15.05. 
  

Section 15.02. Exercise of Conversion Right; Issuance of Common Stock on Conversion; No Adjustment for Interest or Dividends . In order to
exercise the conversion right 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 “Form of Conversion Notice” on the reverse thereof, which is irrevocable, duly completed and manually signed, together with such Notes duly endorsed for transfer. 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 to whom the cash payable on such conversion shall be delivered,
and shall be accompanied by transfer or similar taxes, if required pursuant to Section 15.07, and funds equal to the Interest payable on the next Interest Payment Date to which such holder of the Note is not entitled, if required pursuant to this
Section 15.02. 
  
 In order to exercise the conversion right 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 this Section 15.02 and
any transfer taxes if required pursuant to Section 15.07. 
  
 The
Company will deliver the Settlement Amount to converting holders on the Business Day immediately following the last day of the Cash Settlement Averaging Period. Subject to compliance with any restrictions on transfer if shares issuable on conversion
are to be issued in a name other than that of the Noteholder (as if such transfer were a transfer of the Note or Notes (or portion thereof) so converted), the Company shall issue and shall deliver through the Conversion Agent to such Noteholder at
the office or agency maintained by the Company for such purpose pursuant to Section 5.02, a check or cash in respect of the lesser of the aggregate Principal Amount of Notes being converted and the Conversion Value in respect of such Notes,
calculated by the Company as provided in Section 15.03 and a certificate or certificates for the number of full shares of Common Stock, if any, issuable upon the conversion of such Note or Notes (or portion thereof) so converted as determined by the
Company as provided in Section 15.03, or if the Common Stock is eligible for transfer through The Depository Trust Company, the Company shall make a book-entry transfer of such number of shares of Common Stock through The Depository Trust Company,
and a check or cash in respect of any fractional interest in respect of any share of Common Stock arising upon such conversion. In case any Note of a denomination greater than $1,000 shall be surrendered for partial conversion, and 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 him, a new Note or Notes in authorized denominations in an aggregate Principal Amount equal to the
unconverted portion of the surrendered Note. 
  

 63 

 Each conversion shall be deemed to have been effected as to any such Note (or portion thereof) on the
date on which the requirements set forth above in this Section 15.02 have been satisfied as to such Note (or portion thereof) (such date, the “Conversion Date”), 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. 
  
 Any Note or portion thereof surrendered for conversion during the period from 5:00 p.m., New York City time, on any Regular Record Date to 9:00 a.m., New York City time, on the corresponding Interest Payment Date
shall be accompanied by payment, in immediately available funds or other funds acceptable to the Company, of an amount equal to the Interest otherwise payable on such Interest Payment Date on the Principal Amount being converted; provided
that no such payment need be made (1) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, (2) if the Company has specified a Fundamental Change Repurchase
Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date or (3) to the extent of any overdue Interest, if any overdue Interest exists at the time of conversion with respect to such Note. Except as provided
above in this Section 15.02, no payment or other adjustment shall be made for Interest accrued on any Note converted or for dividends on any shares issued upon the conversion of such Note as provided in this Article 15. 
  
 Upon the conversion of an interest in a Global Note, the Conversion Agent, or
the Custodian at the direction of the Conversion Agent, 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. 
  
 Upon the
conversion of a Note, that portion of the accrued but unpaid Interest with respect to the converted Note shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be paid in full to the holder thereof through delivery of cash
or a combination of cash and the Common Stock, as the case may be (together with the cash payment in lieu of fractional shares, if any) in exchange for the Note being converted pursuant to the provisions hereof; and cash or a combination of cash and
shares of Common Stock, as the case may be (together with any such cash payment in lieu of fractional shares) shall be treated as issued, to the extent thereof, first in exchange for and in satisfaction of the Company’s obligation to pay the
Principal Amount of the converted Note and the accrued but unpaid Interest, and the balance, if any, of such fair market value of such Common Stock (and any such cash payment) shall be treated as issued in exchange for and in satisfaction of the
right to convert the Note being converted pursuant to the provisions hereof. 
  
 Section 15.03. Payment Upon Conversion; Cash Payments in Lieu of Fractional Shares. (a) Upon receipt of a notice of conversion, the Company will deliver to holders in respect of each $1,000 Principal Amount of
Notes being converted a settlement amount (the “Settlement  

  

 64 

 
Amount”) consisting of (i) cash equal to the lesser of $1,000 and the Conversion Value and (ii) to the extent the Conversion Value exceeds
$1,000, a number of shares equal to the sum of, for each day of the ten Trading Day Cash Settlement Averaging Period, (A) 10% of the difference between the Conversion Value and $1,000, divided by (B) the Last Reported Sale Price of the Common Stock
for such day. 
  
 (b) No fractional shares of Common Stock 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, if any, shall be computed on the basis of the aggregate
principal amount of Notes so surrendered. If any fractional share of Common Stock would be issuable upon the conversion of any Note or Notes, the Company shall make an adjustment and payment therefor in cash to the holder of Notes at a price equal
to the average of the Last Reported Sale price of the Common Stock over the Cash Settlement Averaging Period. 
  
 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 (initially 46.7880 shares), 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) If the Company issues shares of Common Stock
as a dividend or distribution on shares of the Common Stock, or effects a share split or share combination, the Conversion Rate will be adjusted based on the following formula: 
  
 

 
  
 where, 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect immediately prior to such event
			
	 CR’
	  	=	  	the Conversion Rate in effect immediately after such event
			
	 OS0
	  	=	  	the number of shares of Common Stock outstanding immediately prior to such event
			
	 OS’
	  	=	  	the number of shares of Common Stock outstanding immediately after such event.

  
 Such adjustment shall become effective
immediately after 9:00 a.m., New York City time, on the Business Day following the date fixed for such determination. The Company will not pay any dividend or make any distribution on shares of Common Stock held in treasury by 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. 
  

 65 

 (b) If the Company issues to all or substantially all holders of its Common Stock any rights or warrants
entitling them for a period of not more than 45 calendar days to subscribe for or purchase shares of Common Stock, at a price per share less than the Last Reported Sale Price of Common Stock on the Business Day immediately preceding the date of
announcement of such issuance, the Conversion Rate will be adjusted based on the following formula (provided that the Conversion Rate will be readjusted to the extent that such rights or warrants are not exercised prior to their expiration):

  
 

 
  
 where, 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect immediately prior to such event
			
	 CR’
	  	=	  	the Conversion Rate in effect immediately after such event
			
	 OS0
	  	=	  	the number of shares of Common Stock outstanding immediately prior to such event
			
	 X
	  	=	  	the total number of shares of Common Stock issuable pursuant to such rights
			
	 Y
	  	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights divided by the average of the Last Reported Sale Prices of Common Stock over the ten
consecutive Trading Day period ending on the Business Day immediately preceding the Record Date for the issuance of such rights.

  
 Such adjustment shall be successively
made whenever any such rights or warrants are issued and shall become effective immediately after 9:00 a.m., New York City time, on the Business Day following the date fixed for such determination. The Company shall not issue any such rights,
options or warrants in respect of shares of Common Stock held in treasury by the Company. 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 less than such Last Reported Sale Price, 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 

  

 66 

 
exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. 
  
 (c) If the Company distributes shares of its capital stock, evidences of its
indebtedness or other assets or property of the Company to all or substantially all holders of the Common Stock, excluding: 
  
 (i) dividends or distributions and rights or warrants referred to in clause (a) or (b) above; and 
  
 (ii) dividends or distributions paid exclusively in cash;

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

 
  
 where, 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect immediately prior to such distribution
			
	 CR’
	  	=	  	the Conversion Rate in effect immediately after such distribution
			
	 SP0
	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Business Day immediately preceding the record date for such
distribution
			
	 FMV
	  	=	  	the fair market value (as determined by the Board of Directors) of the shares of capital stock, evidences of indebtedness, assets or property distributed with respect to each outstanding
share of Common Stock on the Record Date for such distribution.

  
 Such adjustment shall become effective
immediately prior to 9:00 a.m., New York City time, on the Business Day following the date fixed for the determination of stockholders entitled to receive such distribution. 
  
 With respect to an adjustment pursuant to this clause (c) where there has been a payment of a dividend or other distribution on the Common
Stock or shares of capital stock of any class or series, or similar equity interest, of or relating to a subsidiary or other business unit (a “Spin-Off”) the Conversion Rate in effect immediately before 5:00 p.m., New York City
time, on the Record Date fixed for determination of stockholders entitled to receive the distribution will be increased based on the following formula: 
  
 

 
  

 67 

 where, 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect immediately prior to such distribution
			
	 CR’
	  	=	  	the Conversion Rate in effect immediately after such distribution
			
	 FMV0
	  	=	  	the average of the Last Reported Sale Prices of the capital stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock over the first ten
consecutive Trading Day period after the effective date of the Spin-Off
			
	 MP0
	  	=	  	the average of the Last Reported Sale Prices of Common Stock over the first ten consecutive Trading Day period after the effective date of the Spin-Off.

  
 Such adjustment shall occur on the
tenth Trading Day from, and including, the effective date of the Spin-Off. 
  
 (d) If the Company makes any cash dividend or distribution during any quarterly fiscal period to all or substantially all holders of Common Stock, in an aggregate amount that, together with other cash dividends or
distributions made during such quarterly fiscal period, exceeds $0.05 per share (appropriately adjusted from time to time for any share dividends on or subdivisions of the Common Stock), the Conversion Rate will be adjusted based on the following
formula: 
  
 

 
  
 where, 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect immediately prior to the Record Date for such distribution
			
	 CR’
	  	=	  	the Conversion Rate in effect immediately after the Record Date for such distribution
			
	 SP0
	  	=	  	the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period prior to the Business Day immediately preceding the Record Date of such
distribution
			
	 C
	  	=	  	the amount in cash per share the Company distributes to holders of Common Stock that exceeds $0.05 (appropriately adjusted from time to time for any share dividends on, or subdivisions of,
Common Stock).

  

 68 

 Such adjustment shall become effective immediately after 5:00 p.m., New York City time, on the date for such
determination. 
  
 (e) If the Company or any of its Subsidiaries
purchases shares of the Common Stock pursuant to a tender or exchange offer which involves an aggregate per share consideration that exceeds the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date on which
tenders or exchanges may be made pursuant to such tender or exchange offer (such last date, the “Expiration Time”), the Conversion Rate will be increased based on the following formula: 
  
 

 
  
 where, 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect on the date such tender or exchange offer expires
			
	 CR’
	  	=	  	the Conversion Rate in effect on the day next succeeding the date such tender or exchange offer expires
			
	 AC
	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares purchased in such tender or exchange offer
			
	 OS0
	  	=	  	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires
			
	 OS’

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

  
 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. 
  
 If, however, the application of the foregoing formula would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made. 
  
 Except as stated herein, the Company will not adjust the Conversion Rate for the issuance of shares of Common Stock or any securities
convertible into or exchangeable for shares of Common Stock or the right to purchase shares of Common Stock or such convertible or exchangeable securities. 
  

 69 

 (f) [Reserved] 
  

(g) Notwithstanding the foregoing provisions of this Section 15.05, no adjustment shall be made thereunder, nor shall an adjustment be made to the
ability of a Holder of a Note to convert, for any distribution described therein if the Holder will otherwise participate in the distribution without conversion of such Holder’s Notes. 
  
 (h) The Company may (but is not required to) make such increases in the
Conversion Rate, in addition to those required by clauses (a) through (e) of this Section 15.05 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 in
connection with a dividend or distribution of shares (or rights to acquire shares) or any similar event treated as such for income tax purposes. 
  
 To the extent permitted by applicable law, the Company from time to time may increase the Conversion Rate by any amount for any period of at least twenty
days if the Board of Directors shall have made a determination that such increase would be in the best interests of the Company, which determination shall be conclusive. 
  
 (i) No adjustment to the Conversion Rate need be made: 
  
 (i) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the
reinvestment of dividends or interest payable on securities of the Company and the investment of additional optional amounts in shares of Common Stock under any plan; 
  
 (ii) upon the issuance of any shares of Common Stock or options or rights to purchase shares of Common Stock
pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries; 
  
 (iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right, or exercisable, exchangeable or convertible
security not described in (ii) above and outstanding as of the date the Notes were first issued; 
  
 (iv) for a change in the par value of the Common Stock; or 
  
 (v) for accrued and unpaid Interest. 
  
 To the extent the Notes become convertible into cash, assets or property (other than capital stock of the Company or securities to which
Section 15.06 applies), no adjustment shall be made thereafter as to the cash, assets or property. Interest shall not accrue on such cash, assets or property. 
  

(j) 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. The Company will not be required to make an adjustment in the Conversion Rate unless the adjustment would require a change of at least 1% in the Conversion Rate. However, the Company will carry forward any
adjustments that are less than 1% of the Conversion Rate and 

  

 70 

 
make such carried forward adjustments, regardless of whether aggregate adjustment is less than 1% within one year of the first such adjustment carried
forward, upon redemption, upon a Fundamental Change or upon the Stated Maturity. Except as described above in this Section 15.05, the Company will not adjust the Conversion Rate. 
  
 (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 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 Stock 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(e), (each 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 

  

 71 

 
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. 
  
 Section 15.06. Effect of Reclassification, Consolidation, Merger or Sale. If any of the following events 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, binding share exchange or combination of the Company with another Person as a result of which holders of Common Stock shall be entitled to receive cash,
securities or other property 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 cash, securities or other property 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 the kind and amount of cash, securities or other property (and in the
same proportion) receivable upon such reclassification, change, consolidation, merger, binding share exchange, combination, sale or conveyance by a holder of a number of shares of Common Stock issuable upon conversion of such Notes (assuming, for
such purposes, a sufficient number of authorized shares of Common Stock are available to convert all such Notes) immediately prior to such reclassification, change, consolidation, merger, binding share exchange, combination, sale or conveyance
assuming such holder of Common Stock did not exercise his rights of election, if any, as to the kind or amount of cash, securities or other property receivable upon such reclassification, change, consolidation, merger, binding share exchange,
combination, sale or conveyance (provided that, if the kind or amount of cash, securities or other property receivable upon such reclassification, change, consolidation, merger, binding share exchange, combination, sale or conveyance is not the same
for each share of Common Stock in respect of which such rights of election shall not have been exercised (“non-electing share”), then for the purposes of this Section 15.06 the kind and amount of cash, securities or other property
receivable upon such reclassification, change, consolidation, merger, binding share exchange, combination, sale or conveyance for each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the
non-electing shares). Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 15. 
  
 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) calendar days after execution thereof. Failure to deliver such notice shall not affect
the legality or validity of such supplemental indenture. 
  
 The
above provisions of this Section shall similarly apply to successive reclassifications, changes, consolidations, mergers, binding share exchanges, combinations, sales and conveyances. 
  
 If this Section 15.06 applies to any event or occurrence, Section 15.05 shall not apply. 
  

 72 

 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; Compliance with Governmental Requirements; Listing of
Common Stock. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of the 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 covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder
require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will in good faith and as expeditiously as possible, to the extent then
permitted by the rules and interpretations of the Commission (or any successor thereto), endeavor to secure such registration or approval, as the case may be. 
  

The Company further covenants that, if at any time the Common Stock shall be listed on the New York Stock Exchange, Nasdaq National Market or any other
national securities exchange or automated quotation system, the Company 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 such exchange or
automated quotation system, all Common Stock issuable upon conversion of the Notes; provided that if the rules of such 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 the Company or any holder of Notes to determine the Conversion Rate or whether any facts exist which may
require any adjustment 

  

 73 

 
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 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 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 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) calendar 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, 

  

 74 

 
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. Stockholder Rights Plan. To the extent that the Company
has a rights plan in effect upon conversion of the Notes into Common Stock, the Noteholder will receive, in addition to the Common Stock, the rights under the rights plan, unless prior to any conversion, the rights have separated from the Common
Stock, in which case the Conversion Rate will be adjusted at the time of separation as if the Company distributed to all holders of Common Stock, shares of the Company’s capital stock, evidences of indebtedness or assets as described in Section
15.04(c) above, subject to readjustment in the event of the expiration, termination or redemption of such rights. In lieu of any such adjustment, the Company may amend such applicable stockholder rights agreement to provide that upon conversion of
the Notes the holders will receive, in addition to the Common Stock issuable upon such conversion, the rights which would have attached to such Common Stock if the rights had not become separated from the Common Stock under such applicable
stockholder rights agreement. 
  
 ARTICLE 16 
 SUBSIDIARY GUARANTEES 
  
 Section 16.01. Subsidiary Guarantees. (a) Subject to the provisions of this Article 16, the Subsidiary Guarantor hereby irrevocably and
unconditionally guarantees on an unsecured senior basis to each holder and to the Trustee and its successors and assigns (i) 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 of or interest on the Notes and all other monetary obligations of the Company under this Indenture and the Notes
and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Company whether for fees, expenses, indemnification or otherwise under this Indenture and the Notes (all the foregoing being hereinafter
collectively called the “Guaranteed Obligations”). Subject to Section 16.02, the Subsidiary Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent
from the Subsidiary Guarantor, and that the Subsidiary Guarantor shall remain bound under this Article 16 notwithstanding any extension or renewal of any Guaranteed Obligation. 
  
 (b) To the extent permitted by law, the Subsidiary 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. The Subsidiary Guarantor waives notice of any default under the Notes or the Guaranteed Obligations. The obligations of the Subsidiary Guarantor
hereunder shall not be affected by (i) the failure of any holder 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 

  

 75 

 
terms or provisions of this Indenture, the Notes or any other agreement; (iv) the release of any security held by any holder or the Trustee for the
Guaranteed Obligations or any of them; (v) the failure of any holder or the Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (vi) any change in the ownership of the Subsidiary Guarantor, except as
provided in Section 16.02(b). 
  
 (c) The Subsidiary Guarantor
agrees that its Subsidiary Guarantee constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any holder or the Trustee to any security held
for payment of the Guaranteed Obligations. 
  
 (d) Except as
expressly set forth in Section 16.02, the obligations of the Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, 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 the Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any holder 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 the Subsidiary Guarantor or would otherwise operate as a discharge of the Subsidiary Guarantor as a matter of law or equity. 
  
 (e) The Subsidiary Guarantor agrees that its Subsidiary Guarantee shall
remain in full force and effect until payment in full of all the Guaranteed Obligations. The Subsidiary Guarantor further agrees that its Subsidiary Guarantee 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 on any Guaranteed Obligation is rescinded or must otherwise be restored by any holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise. 
  
 (f) In furtherance of the foregoing and not in limitation of any other right
which any holder or the Trustee has at law or in equity against the Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due,
whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, the Subsidiary 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 holders or the Trustee an amount equal to the sum of (i) the unpaid principal amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not
prohibited by law) and (iii) all other monetary obligations of the Company to the holders and the Trustee. 
  
 (g) The Subsidiary Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the holders in respect of any Guaranteed
Obligations guaranteed hereby until payment in full of all Guaranteed Obligations. The Subsidiary Guarantor further 

  

 76 

 
agrees that, as between it, on the one hand, and the holders 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 its Subsidiary Guarantee, 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 the Subsidiary Guarantor or the
Company for the purposes of this Section 16.01. 
  
 (h) The
Subsidiary Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any holder in enforcing any rights under this Section 16.01. 
  
 (i) Upon request of the Trustee, the Subsidiary 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 16.02. Limitation on Liability. (a) Any other term or provision of this Indenture to the contrary notwithstanding, (i) the maximum
aggregate amount of the Guaranteed Obligations guaranteed hereunder by the Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to the Subsidiary Guarantor, voidable
under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally and (ii) no waiver, modification, indulgence or circumstance shall, without the consent of the Guarantors,
increase the principal amount of a Debenture or the interest rate thereon except as provided in such Note. 
  
 (b) The Subsidiary Guarantee shall terminate and be of no further force in effect and the Subsidiary Guarantor shall be deemed to be released from all
obligations under this Article 16 (without any further action by the Trustee or the holders) upon (i) the sale or other disposition of all or substantially all of the assets of the Subsidiary Guarantor (including by way of any merger or
consolidation where the Subsidiary Guarantor is not the surviving entity of such consolidation or merger) or (ii) the sale or other disposition of all of the capital stock of the Subsidiary Guarantor, in each case, other than the sale or other
disposition to the Company or an Affiliate of the Company; provided, however, that such merger, consolidation, sale, or other disposition 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). 
  
 Section 16.03. Successors and Assigns. This Article 16 shall be binding upon the Subsidiary Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee
and the holders and, in the event of any transfer or assignment of rights by any holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Debentures shall automatically extend to and be vested in such
transferee or assignee, all subject to the terms and conditions of this Indenture. 
  
 Section 16.04. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the holders in exercising any right, power or privilege under this Article 16 shall operate as a 

  

 77 

 
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 holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 16 at law, in equity, by statute or otherwise. 
  
 Section 16.05. Modification. No modification, amendment or waiver of
any provision of this Article 16, nor the consent to any departure by the Subsidiary 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 the Subsidiary Guarantor in any case shall entitle the Subsidiary Guarantor to any other or further notice or demand in the same, similar or other
circumstances. 
  
 ARTICLE 17

Repurchase Date, as the case may be, and no interest shall accrue for the period from and after such date.

qualified under the Trust Indenture Act prior to the time such qualification is in fact required under the terms of the Trust Indenture Act, nor shall it constitute any admission or acknowledgment by any party to the Indenture that any such
qualification is required prior to the time such qualification is in fact required under the terms of the Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with another provision hereof which is required to be included in
an indenture qualified under the Trust Indenture Act, such required provision shall control. 
  
 Section 17.09. No Security Interest Created. Except as provided in Section 8.06, nothing in this Indenture or in the Notes, expressed or implied, shall be construed to constitute a security interest under the

 Section 17.12.
Authenticating Agent. The Trustee may appoint an authenticating agent that shall be authorized to act on its behalf, and subject to its direction, in the authentication and delivery of Notes in connection with the original issuance thereof
and transfers and exchanges of Notes hereunder, including under Sections 2.04, 2.05, 2.06, 2.07, 3.02 and 3.08, as fully to all intents and purposes as though the authenticating agent had been expressly authorized by this Indenture and those
Sections to authenticate and deliver Notes. For all purposes of this Indenture, the authentication and delivery of Notes by the authenticating agent shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a
certificate of authentication executed on behalf of the Trustee by an authenticating agent shall be deemed to satisfy any requirement hereunder or in the Notes for the Trustee’s certificate of authentication. Such authenticating agent shall at
all times be a Person eligible to serve as trustee hereunder pursuant to Section 8.09. 
  

 80 

 Any corporation into which any authenticating agent may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, consolidation or conversion to which any authenticating agent shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of any authenticating
agent, shall be the successor of the authenticating agent hereunder, if such successor corporation is otherwise eligible under this Section 17.12, without the execution or filing of any paper or any further act on the part of the parties hereto or
the authenticating agent or such successor corporation. 
  
 Any
authenticating agent may at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of any authenticating agent by giving written notice of termination to such
authenticating agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any authenticating agent shall cease to be eligible under this Section, the Trustee shall either promptly appoint
a successor authenticating agent or itself assume the duties and obligations of the former authenticating agent under this Indenture and, upon such appointment of a successor authenticating agent, if made, shall give written notice of such
appointment of a successor authenticating agent to the Company and shall mail notice of such appointment of a successor authenticating agent to all holders of Notes as the names and addresses of such holders appear on the Note Register. 

 
 The Company agrees to pay to the authenticating agent from time to time
such reasonable compensation for its services as shall be agreed upon in writing between the Company and the authenticating agent. 
  
 The provisions of Sections 8.02, 8.03, 8.04 and 9.03 and this Section 17.12 shall be applicable to any authenticating agent. 
  
 Section 17.13. Execution in Counterparts. This Indenture may be
executed in any number of counterparts, each of which shall be an original, but such counterparts shall together constitute but one and the same instrument. 
  
 Section 17.14. Severability. In case any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable, then (to the
extent permitted by law) the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
  
 Section 17.15. Tax Treatment. The Company agrees, and by acceptance of beneficial ownership interest in the Notes each beneficial holder of the
Notes will be deemed to have agreed, for United States federal income tax purposes to treat the Notes as indebtedness that is not subject to the contingent payment debt instrument regulations under Treas. Reg. Sec. 1.1275-4. 
  
 The Bank of New York Trust Company, N.A. hereby accepts the trusts in this
Indenture declared and provided, upon the terms and conditions herein above set forth.

 FORM OF REVERSE OF NOTE

  
 RYERSON TULL, INC. 
  
 3.50% CONVERTIBLE SENIOR NOTE DUE 2024 
  
 This Note is one of a duly authorized issue of Notes of the Company,
designated as its 3.50% Convertible Senior Notes due 2024 (herein called the “Notes”), limited in aggregate Principal Amount to $145,000,000 (or up to $175,000,000 if the Initial Purchasers exercise their option in full), issued and
to be issued under and pursuant to an Indenture dated as of November 10, 2004 (herein called the “Indenture”), among the Company, Ryerson Tull Procurement Corporation (the “Subsidiary Guarantor” which term includes
any successor corporation under the Indenture) and The Bank of New York Trust Company, N.A., 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 Subsidiary Guarantor and the holders of the Notes. 
  
 The payment by the Company of the principal of and interest on the Notes is fully and unconditionally guaranteed by the
Subsidiary Guarantor on a senior unsecured basis pursuant to the terms of the Indenture. 
  
 In case an Event of Default shall have occurred and be continuing, the Principal Amount of and accrued Interest 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, the Subsidiary
Guarantor 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 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, subject to the exceptions set forth in Section 11.02 of the Indenture. 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,
subject to the exceptions set forth in the Indenture. 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 or the Subsidiary Guarantor, which are absolute and unconditional, to pay the Principal Amount of and Interest on this Note at the place, at the respective times, at the rate and in the coin or currency herein prescribed. 

 

 A-6 

 Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months.

  
 The Notes are issuable in fully registered form, without
interest 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 November 5, 2009, the Notes may be redeemed at the option of the Company, in whole or in part, in cash upon mailing a notice of such redemption not less than 20 calendar days but not more than 60 calendar days before
the Redemption Date to the holders of Notes at their last registered addresses, all as provided in the Indenture, at a Redemption Price equal to 100% of the Principal Amount of notes being redeemed plus accrued and unpaid Interest to, but not
including, the Redemption Date; provided that if the applicable Redemption Date is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, Interest will be paid on the Redemption Date to the holder on the
applicable record date. In no event will any Security be redeemable at the option of the Company before November 5, 2009. The Company may not give notice of any redemption of the Notes if a default in the payment of Interest on the Notes has
occurred and is continuing. 
  
 The Notes are not subject to
redemption through the operation of any sinking fund. 
  
 If a
Fundamental Change occurs at any time prior to maturity of the Notes, the holders will have the right to require the Company to repurchase all or any portion of the Notes on a Fundamental Change Repurchase Date specified by the Company, which shall
be no later than 30 calendar days after notice thereof, in integral multiples of $1,000 Principal Amount at a Fundamental Change Repurchase Price equal to 100% of the Principal Amount thereof, together with accrued Interest to, but not including,
the Fundamental Change Repurchase Date; provided that if the applicable Fundamental Change Repurchase Date is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, the 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 record date instead of the holders surrendering such Notes for repurchase on such date. The Company shall mail to all holders of record
of the Notes a notice of the occurrence of a Fundamental Change and of the repurchase right arising as a result thereof on or before the 30th calendar day after the occurrence of such Fundamental Change. To exercise such right, a holder must deliver
to the Paying Agent such Notes with the form entitled “Form of Fundamental Change Repurchase Election” on the reverse thereof duly completed, together with such Notes, duly endorsed for transfer (or if such Notes are Global Notes,
book-entry transfer of such Notes) at any time prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change Repurchase Date. 
  
 Subject to the terms and conditions of the Indenture, the holders will have the right to require the Company to repurchase
all or any portion of the Notes on November 1, 2009, November 1, 2014 and November 1, 2019 in integral multiples of $1,000 Principal Amount at a 

  

 A-7 

 
Company Repurchase Price of 100% of the Principal Amount, plus any accrued and unpaid Interest on such Note to, but not including, the Company Repurchase
Date; provided that the Interest payable on the applicable Company Repurchase Date shall be paid on such Interest Payment Date to the holders of record of such Notes on the applicable record date instead of the holders surrendering such Notes
for repurchase on such date. To exercise such right, a holder must deliver to the Paying Agent such Notes with the form entitled “Form of Company Repurchase Election” on the reverse thereof duly completed, together with such Notes,
duly endorsed for transfer (or if such Notes are Global Notes, book-entry transfer of such Notes) at any time from 9:00 a.m., New York City time, on the date that is 20 Business Days prior to such Company Repurchase Date until 5:00 p.m., New York
City time, on the Business Day immediately preceding the Company Repurchase Date. 
  
 The Company Repurchase Price to be paid on any of November 1, 2009, November 1, 2014 and November 1, 2019 and the Fundamental Change Repurchase Price to be paid on any Fundamental Change Repurchase Date shall be paid
in cash, subject to the terms and conditions of the Indenture. 
  
 Holders have the right to withdraw any Repurchase Election by delivering to the Paying Agent a written notice of withdrawal up to 5:00 p.m., New York City time, on the Business Day immediately preceding the Repurchase Date, all as provided
in the Indenture. 
  
 If on the Repurchase Date money sufficient
to pay the Repurchase Price with respect to all Notes or portions thereof to be repurchased as of any Repurchase Date is deposited with the Paying Agent, then on and after such Repurchase Date, Interest will cease to accrue on such Notes (or
portions thereof), 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, on or prior to the Trading Day preceding the Stated
Maturity, the holder hereof has the right, at its option, to convert each $1,000 principal amount of this Note into 46.7880 shares of Common Stock (a Conversion Price of approximately $21.37 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 (in certificated form) with the form entitled “Form of Conversion Notice” on the reverse hereof duly completed and
manually signed, 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 together with any funds required pursuant
to the terms of the Indenture, 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. In order to exercise the conversion right with respect to any
interest in a Global Note, the holder must complete the appropriate instruction form pursuant to the Depositary’s book-entry conversion program, deliver by book-entry delivery an interest in such Global Note, furnish appropriate endorsements
and transfer documents if required pursuant to the terms of the Indenture. Upon conversion, the Company will deliver cash equal to the lesser of the aggregate principal amount 

  

 A-8 

 
of Notes being converted and the Conversion Value, and shares of Common Stock in respect of the remainder, if any, of the Conversion Value. 
  
 If the Company (i) is a party to a consolidation, merger, statutory share
exchange or combination, (ii) reclassifies the Common Stock, or (iii) sells or conveys its properties and assets substantially as an entirety to any Person, the right to convert a Security into shares of Common Stock may be changed into a right to
convert it into the kind or amount of cash, securities or other property receivable upon such event, in each case in accordance with the Indenture. 
  
 In addition, following certain corporate transactions as set forth in Section 15.01(b) of the Indenture that occur prior to November 1, 2009 and that also
constitute a Fundamental Change, a Noteholder who elects to convert its Notes in connection with such corporate transaction will be entitled to receive Additional Shares of Common Stock upon conversion in certain circumstances. 
  
 No adjustment in respect of Interest on any Note converted (other than the
payment of Additional Interest, if any) or dividends on any shares issued upon conversion of such Note will be made upon any conversion except as set forth in the next sentence. If this Note (or portion hereof) is surrendered for conversion during

 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.

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

 FORM OF REVERSE OF NOTE

  
 RYERSON TULL, INC. 
  
 3.50% CONVERTIBLE SENIOR NOTE DUE 2024 
  
 This Note is one of a duly authorized issue of Notes of the Company,
designated as its 3.50% Convertible Senior Notes due 2024 (herein called the “Notes”), limited in aggregate Principal Amount to $145,000,000 (or up to $175,000,000 if the Initial Purchasers exercise their option in full), issued and
to be issued under and pursuant to an Indenture dated as of November 10, 2004 (herein called the “Indenture”), among the Company, Ryerson Tull Procurement Corporation (the “Subsidiary Guarantor” which term includes
any successor corporation under the Indenture) and The Bank of New York Trust Company, N.A., 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 Subsidiary Guarantor and the holders of the Notes. 
  
 The payment by the Company of the principal of and interest on the Notes is fully and unconditionally guaranteed by the
Subsidiary Guarantor on a senior unsecured basis pursuant to the terms of the Indenture. 
  
 In case an Event of Default shall have occurred and be continuing, the Principal Amount of and accrued Interest 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, the Subsidiary
Guarantor 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 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, subject to the exceptions set forth in Section 11.02 of the Indenture. 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,
subject to the exceptions set forth in the Indenture. 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 or the Subsidiary Guarantor, which are absolute and unconditional, to pay the Principal Amount of and Interest on this Note at the place, at the respective times, at the rate and in the coin or currency herein prescribed. 

 

 6 

 Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months.

  
 The Notes are issuable in fully registered form, without
interest 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 November 5, 2009, the Notes may be redeemed at the option of the Company, in whole or in part, in cash upon mailing a notice of such redemption not less than 20 calendar days but not more than 60 calendar days before
the Redemption Date to the holders of Notes at their last registered addresses, all as provided in the Indenture, at a Redemption Price equal to 100% of the Principal Amount of notes being redeemed plus accrued and unpaid Interest to, but not
including, the Redemption Date; provided that if the applicable Redemption Date is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, Interest will be paid on the Redemption Date to the holder on the
applicable record date. In no event will any Security be redeemable at the option of the Company before November 5, 2009. The Company may not give notice of any redemption of the Notes if a default in the payment of Interest on the Notes has
occurred and is continuing. 
  
 The Notes are not subject to
redemption through the operation of any sinking fund. 
  
 If a
Fundamental Change occurs at any time prior to maturity of the Notes, the holders will have the right to require the Company to repurchase all or any portion of the Notes on a Fundamental Change Repurchase Date specified by the Company, which shall
be no later than 30 calendar days after notice thereof, in integral multiples of $1,000 Principal Amount at a Fundamental Change Repurchase Price equal to 100% of the Principal Amount thereof, together with accrued Interest to, but not including,
the Fundamental Change Repurchase Date; provided that if the applicable Fundamental Change Repurchase Date is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, the 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 record date instead of the holders surrendering such Notes for repurchase on such date. The Company shall mail to all holders of record
of the Notes a notice of the occurrence of a Fundamental Change and of the repurchase right arising as a result thereof on or before the 30th calendar day after the occurrence of such Fundamental Change. To exercise such right, a holder must deliver
to the Paying Agent such Notes with the form entitled “Form of Fundamental Change Repurchase Election” on the reverse thereof duly completed, together with such Notes, duly endorsed for transfer (or if such Notes are Global Notes,
book-entry transfer of such Notes) at any time prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change Repurchase Date. 
  
 Subject to the terms and conditions of the Indenture, the holders will have the right to require the Company to repurchase
all or any portion of the Notes on November 1, 2009, November 1, 2014 and November 1, 2019 in integral multiples of $1,000 Principal Amount at a 

  

 7 

 
Company Repurchase Price of 100% of the Principal Amount, plus any accrued and unpaid Interest on such Note to, but not including, the Company Repurchase
Date; provided that the Interest payable on the applicable Company Repurchase Date shall be paid on such Interest Payment Date to the holders of record of such Notes on the applicable record date instead of the holders surrendering such Notes
for repurchase on such date. To exercise such right, a holder must deliver to the Paying Agent such Notes with the form entitled “Form of Company Repurchase Election” on the reverse thereof duly completed, together with such
Notes, duly endorsed for transfer (or if such Notes are Global Notes, book-entry transfer of such Notes) at any time from 9:00 a.m., New York City time, on the date that is 20 Business Days prior to such Company Repurchase Date until 5:00 p.m., New
York City time, on the Business Day immediately preceding the Company Repurchase Date. 
  
 The Company Repurchase Price to be paid on any of November 1, 2009, November 1, 2014 and November 1, 2019 and the Fundamental Change Repurchase Price to be paid on any Fundamental Change Repurchase Date shall be paid
in cash, subject to the terms and conditions of the Indenture. 
  
 Holders have the right to withdraw any Repurchase Election by delivering to the Paying Agent a written notice of withdrawal up to 5:00 p.m., New York City time, on the Business Day immediately preceding the Repurchase Date, all as provided
in the Indenture. 
  
 If on the Repurchase Date money sufficient
to pay the Repurchase Price with respect to all Notes or portions thereof to be repurchased as of any Repurchase Date is deposited with the Paying Agent, then on and after such Repurchase Date, Interest will cease to accrue on such Notes (or
portions thereof), 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, on or prior to the Trading Day preceding the Stated
Maturity, the holder hereof has the right, at its option, to convert each $1,000 principal amount of this Note into 46.7880 shares of Common Stock (a Conversion Price of approximately $21.37 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 (in certificated form) with the form entitled “Form of Conversion Notice” on the reverse hereof duly completed and
manually signed, 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 together with any funds required pursuant
to the terms of the Indenture, 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. In order to exercise the conversion right with respect to any
interest in a Global Note, the holder must complete the appropriate instruction form pursuant to the Depositary’s book-entry conversion program, deliver by book-entry delivery an interest in such Global Note, furnish appropriate endorsements

of Notes being converted and the Conversion Value, and shares of Common Stock in respect of the remainder, if any, of the Conversion Value. 
  
 If the Company (i) is a party to a consolidation, merger, statutory share
exchange or combination, (ii) reclassifies the Common Stock, or (iii) sells or conveys its properties and assets substantially as an entirety to any Person, the right to convert a Security into shares of Common Stock may be changed into a right to
convert it into the kind or amount of cash, securities or other property receivable upon such event, in each case in accordance with the Indenture. 
  
 In addition, following certain corporate transactions as set forth in Section 15.01(b) of the Indenture that occur prior to November 1, 2009 and that also
constitute a Fundamental Change, a Noteholder who elects to convert its Notes in connection with such corporate transaction will be entitled to receive Additional Shares of Common Stock upon conversion in certain circumstances. 
  
 No adjustment in respect of Interest on any Note converted (other than the
payment of Additional Interest, if any) or dividends on any shares issued upon conversion of such Note will be made upon any conversion except as set forth in the next sentence. If this Note (or portion hereof) is surrendered for conversion during
the period from 5:00 p.m., New York City time, on any record date for the payment of Interest to 9:00 a.m., New York City time, on the immediately following Interest Payment Date, this Note (or portion hereof being converted) must be accompanied by
payment, in immediately available funds or other funds acceptable to the Company, of an amount equal to the Interest otherwise payable on such Interest Payment Date on the Principal Amount being converted; provided that no such payment shall
be required (1) if the Company has specified a Redemption Date that is after a record date and on or prior to the corresponding Interest Payment Date, (2) if the Company has specified a Fundamental Change Repurchase Date that is after a record date
and on or prior to the corresponding Interest Payment Date or (3) to the extent of any overdue Interest, if any overdue Interest exists at the time of conversion with respect to such Note. 
  
 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. 
  
 A Note in respect of which a holder is exercising its right to require
repurchase upon a Fundamental Change or repurchase on a Repurchase Date may be converted only if such holder withdraws its election to exercise such right in accordance with the terms of the Indenture. 
  
 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 Subsidiary Guarantor, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Note Registrar may deem and
treat the registered 

  

 9 

 
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. 
  
 No recourse for the payment of the Principal Amount of or Interest on 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 or the
Subsidiary Guarantor 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 the Subsidiary Guarantor or of any successor corporation, either directly or through the Company or the Subsidiary Guarantor 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. 
  
 Terms used in this Note and defined in the Indenture are used herein as
therein defined.
