 7 








 Any of the Notes may have such letters, numbers or other marks of identification and such notations,
legends or endorsements as the officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Supplemental Indenture, or as may be required by the
Depositary, as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed or designated for
issuance, or to conform to usage or to indicate any special limitations or restrictions to which any particular Notes are subject. 
 A
Global Note shall represent such principal amount of the Outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate principal amount of Outstanding Notes from time to time endorsed thereon and that the
aggregate principal amount of Outstanding Notes represented thereby may from time to time be increased or reduced to reflect repurchases, conversions, transfers or exchanges permitted hereby. Any endorsement of a Global Note to reflect the amount of
any increase or decrease in the amount of Outstanding Notes represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in such manner and upon instructions given by the Holder of such Notes in accordance with
this Supplemental Indenture. Payment of principal and accrued and unpaid interest on a Global Note shall be made to the Holder of such Note on the date of payment, unless a Record Date or other means of determining Holders eligible to receive
payment is provided for herein. 
 The terms and provisions contained in the form of Note attached as Exhibit A hereto are incorporated
herein and shall constitute, and are hereby expressly made, a part of this Supplemental Indenture and to the extent applicable, the Company and the Trustee, by their execution and delivery of this Supplemental Indenture, expressly agree to such
terms and provisions and to be bound thereby. 
 Section 2.03. Date and Denomination of Notes; Payments of Interest The Notes

Payment Date shall mean the June 1 or December 1 preceding the applicable June 15 or December 15 Interest Payment Date, respectively.

 (b) Intentionally Omitted. 
 (c) Intentionally Omitted. 
 (d) The
Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this instrument or under applicable law with respect to any transfer of any interest in any 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 instrument, and to examine the same to determine substantial compliance as to
form with the express requirements hereof. 
 (e) So long as the Notes are eligible for book-entry settlement with the Depositary, unless
otherwise required by law, all Notes shall be represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of
beneficial interests in a Global Note, which does not involve the issuance of a definitive Note, shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Supplemental Indenture (including the
restrictions on transfer set forth herein) and the procedures of the Depositary therefor. 
 Section 2.07. Additional Notes;
Repurchases The Company may, without the consent of the Noteholders and notwithstanding Section 2.01, increase the principal amount of the Notes by issuing additional Notes (“Additional Notes”) of the same series as the
Initial Notes in the future in an unlimited aggregate principal amount on the same terms and conditions, except for any differences in the issue price and interest accrued prior to the issue date of the Additional Notes and, at the option of the
Company, the first payment of interest following the issue date of such Additional Notes; provided that such differences do not cause the Additional Notes to constitute a different class of securities than the Notes for U.S. federal income
tax purposes; provided further, that the Additional Notes have the same CUSIP number as the Initial Notes; and provided further, however, that the Additional Notes may have a different CUSIP number on a temporary basis if necessary to
comply with applicable U.S. securities laws. The Notes and any Additional Notes shall rank equally and ratably and shall be treated as a single class for all purposes under the Base Indenture and this Supplemental Indenture including, without
limitation, for purposes of any waivers, supplements or amendments to the Indenture requiring the approval of Holders of the Notes and any offers to purchase the Notes. All provisions of the Indenture shall be construed and interpreted to permit the
issuance of such Additional Notes and to allow such Additional Notes to become fungible and interchangeable with the Initial Notes issued under the Indenture. No Additional Notes may be issued if an Event of Default has occurred with respect to the
Notes and is continuing.

 PARTICULAR COVENANTS OF
THE COMPANY 
 Section 4.01. Payment of Principal and Interest 
 (a) Section 307, Section 1001 and Section 1003 of the Base Indenture shall apply to the Notes, subject to Section 8.03 hereof;
provided, however, that, with respect to any Noteholder with an aggregate principal amount in excess of $2,000,000, at the application of such Holder in writing to the Security Registrar not later than the relevant Record Date, accrued
and unpaid interest on such Holder’s Notes shall be paid on the corresponding Interest Payment Date by wire transfer in immediately available funds to such Holder’s account in the United States supplied by such Holder from time to time to
the Trustee and Paying Agent (if different from Trustee); provided further that payment of accrued and unpaid interest made to the Depositary shall be paid by wire transfer in immediately available funds in accordance with such wire transfer
instructions and other procedures provided by the Depositary from time to time. 
 (b) Except as otherwise provided in this
Section 4.01, a Holder of any Notes at 5:00 p.m. New York City time, on a Record Date shall be entitled to receive interest on such Notes on the corresponding Interest Payment Date. A Holder of any Notes as of a Record Date that are
converted after 5:00 p.m. New York City time on such Record Date and prior to the Opening of Business on the corresponding Interest Payment Date shall be entitled to receive accrued and unpaid interest on the principal amount of such Notes,
notwithstanding the conversion of such Notes prior to such Interest Payment Date. However, a Holder that surrenders any Notes for conversion after 5:00 p.m. New York City time on a Record Date and prior to the Opening of Business on the
corresponding Interest Payment Date shall be required to pay the Company an amount equal to the accrued and unpaid interest payable by the Company with respect to such Notes on such Interest Payment Date at the time such Holder surrenders such Notes
for conversion, provided, however, that this sentence shall not apply to a Holder that converts Notes: 
 (i) to
the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Notes; 
  

 10 








 (ii) in connection with a Fundamental Change in which the Company has specified a
Fundamental Change Repurchase Date that is after a Record Date and on or prior to the next Interest Payment Date; or 
 (iii)
after 5:00 p.m., New York City time on the Record Date immediately preceding the Maturity Date. 
 Accordingly, a Holder that converts Notes under any
of the circumstances described in clauses (i), (ii) or (iii) above will not be required to pay to the Company an amount equal to the accrued and unpaid interest payable by the Company with respect to such Notes on the relevant
Interest Payment Date. 
 (c) Notwithstanding anything to the contrary in the Indenture, the Company may pay accrued and unpaid interest
(including Additional Interest, if any) to a Person other than the Holder of record on the Record Date immediately prior to the Maturity Date. On the Maturity Date, the Company shall pay accrued and unpaid interest only to the Person to whom the
Company pays the principal amount of the Notes. 
 Section 4.02. Maintenance of Office or Agency for Conversion Agent If at any
time the Conversion Agent is not the Trustee or an office or agency designated or appointed by the Trustee, the Company will give prompt written notice to the Trustee of the location of such Conversion Agent. If at any time the Company shall fail to
maintain an office or agency for the Conversion Agent, presentations, surrenders, notices and demands related to conversions of Notes may be made or served at the Corporate Trust Office or the office or agency of the Trustee in the Borough of
Manhattan, the City of New York. 
 Section 4.03. Reports by Company 
 (a) The provisions of Section 1005 of the Base Indenture shall not be applicable to the Notes. 
 (b) The Company shall deliver to the Trustee copies of the annual reports and of the information, documents and other reports (or copies of such portions
of any of the foregoing as the Commission may by rules and regulations prescribe) that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act with the Trustee within 15 days after the Company is required
to file such reports, information and documents with the Commission. All required reports, information and documents referred to in this Section 4.03(b) shall be deemed to be delivered to the Trustee at the time such reports, information and
documents are publicly filed with the Commission via the Commission’s EDGAR and/or IDEA filing system (or any successor system). 
  

 11 








 (c) Delivery of such reports, information and documents to the Trustee is for informational purposes
only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants
hereunder (as to which the Trustee is entitled to conclusively rely exclusively on an Officers’ Certificate). Notwithstanding anything to the contrary in this Section 4.03, the Company, to the extent permitted under the Trust Indenture
Act, shall not be required to deliver to the Trustee or the Holders any material for which the Company has sought and received confidential treatment by the Commission. 
 Section 4.04. Subsidiary Guarantors 
 (a) The Company shall cause each Wholly Owned Domestic
Subsidiary that guarantees any unsecured indebtedness of the Company (“Guaranteed Indebtedness”) to, within 10 Business Days of becoming a guarantor of such Guaranteed Indebtedness (a) execute and deliver a supplemental
indenture to the Base Indenture providing for a Guarantee of payment of the Notes by such Wholly Owned Domestic Subsidiary, and (b) waive, and not in any manner whatsoever claim or take the benefit or advantage of, any rights of reimbursement,
indemnity or subrogation or any other rights against the Company or any other Subsidiary as a result of any payment by such Subsidiary under its Guarantee until the Notes have been paid in full. 
 (b) After the execution of a supplemental indenture pursuant to this Section 4.04, such new Wholly Owned Domestic Subsidiary party thereto shall be
a Guarantor of the Notes for all purposes of this Indenture. 
 (c) If the Guaranteed Indebtedness is (A) pari passu in right of
payment with the Notes or any Guarantee, than the guarantee of such Guaranteed Indebtedness shall be pari passu in right of payment with, or subordinated to, the Guarantee of the Notes or (B) subordinated in right of payment to the Notes
or any Guarantee, then the guarantee of such Guaranteed Indebtedness shall be subordinated in right of payment to the Guarantee of the Notes at least to the extent that the Guaranteed Indebtedness is subordinated to the Notes or the Guarantee.

 (d) Notwithstanding the foregoing, any Guarantee of the Notes pursuant to this Section 4.04 shall be automatically and
unconditionally released and discharged in accordance with Section 11.05 hereof. 
 Section 4.05. Exclusion of Certain
Provisions From Base Indenture Article Fourteen of the Base Indenture shall not apply to the Notes.

 ARTICLE V 
 DEFAULTS AND REMEDIES 
 Section 5.01. Events of Default The provisions of
Section 501(1), Section 501(2) and Section 501(3) of the Base Indenture shall not be applicable to the Notes. As contemplated under Section 301 and Section 501(9) of the Base Indenture, the following events, in addition to
the events described in clauses (4), (5), (6), (7) and (8) of the Base Indenture, shall be Events of Default with respect to the Notes: 
 (a) failure by the Company to pay any interest (including Additional Interest, if any) on the Notes when due and such failure continues for a period of 30 calendar days; 
 (b) failure by the Company to pay principal of the Notes when due at the Maturity Date, or failure by the Company to pay the repurchase
price payable, in respect of any Notes when due; 
 (c) failure by the Company to deliver shares of Common Stock upon the
conversion of any Notes and such failure continues for five calendar days following the scheduled settlement date for such conversion; 
 (d) failure by the Company for a period of five calendar days to issue a Fundamental Change Company Notice in accordance with Section 9.02 when due; and 
 (e) any Guarantee provided by any Significant Subsidiary shall be held in any judicial proceeding to be unenforceable or invalid or shall
cease for any reason to be in full force and effect or any Guarantor, or any person acting on behalf of any Guarantor, shall deny or disaffirm its obligations under any Guarantee. 
 The Company shall be required to notify the Trustee within five (5) Business Days of it becoming aware of the occurrence of any default under the
Indenture with respect to the Notes. 
 Section 5.02. Additional Interest 
 (a) Notwithstanding anything to the contrary in the Indenture, the failure by the Company to comply with Section 4.03, and for any failure to comply
with the requirements of Section 314(a)(1) of the Trust Indenture Act (each, a “Filing Failure”), will not constitute an Event of Default for the 365 days after the occurrence of such Filing Failure provided the Company pays
additional interest on the Notes (“Additional Interest”) at an annual rate equal to 0.50% of the principal amount of the Notes. In the event the Company does not elect to pay the Additional Interest upon a Filing Failure in
accordance with this Section 5.02, such Filing Failure will constitute an Event of Default under the Indenture and the Notes will be subject to acceleration in accordance with Section 502 of the Base Indenture. The Additional Interest will
accrue on all Outstanding Notes from and including the date on which a Filing Failure first occurs to but not including the 365th day thereafter (or such earlier date on which the Filing Failure shall have been cured or waived). On such 365th day,
the Notes will be subject to acceleration in accordance with Section 502 of the Base Indenture if the Filing Failure is continuing. 
  

 13 








 (b) For the avoidance of doubt, this Section 5.02 will not affect the rights of Holders of Notes in
the event of the occurrence of any other Event of Default. 
 Section 5.03. Waiver of Past Defaults 
 Section 513 of the Base Indenture is deleted in its entirety and replaced with the following: 
 The Holders of not less than a majority in principal amount of the Notes outstanding may, on behalf of the Holders of all the Notes, consent to the
waiver of any past default or Event of Default under the Indenture and its consequences, except: 
  

	 	(1)	failure by the Company to pay principal of or interest (including Additional Interest, if any) on the Notes when due; 

  

	 	(2)	failure by the Company to deliver shares of Common Stock upon the conversion of any Notes; 

  

	 	(3)	failure by the Company to pay the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date in connection with a Holder of Notes exercising its repurchase rights
in accordance with the Indenture; or 

  

	 	(4)	failure of the Company to comply with a covenant or provision of the Indenture which under Article Nine cannot be modified or amended without the consent of the Holder of each
Outstanding Security of such series affected. 

 Upon any such waiver, such default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured, for every purpose of this Indenture and the Notes; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. 
 Section 5.04. Article Five of Base Indenture Except as amended, supplemented or modified by Sections 5.01 and 5.03 hereof, all of the
provisions of Article Five of the Base Indenture shall be applicable to the Notes. 
 ARTICLE VI

 (a) Without the consent of any Holders of the

	 	(3)	to conform the provisions of the Indenture to the “Description of Notes” section contained in the Company’s final prospectus supplement related to the Notes dated
June 2, 2009; and 

  

	 	(4)	to increase the Conversion Rate. 

 (b) Solely with respect
to the Notes, clause 901(10) of the Base Indenture is hereby deleted in its entirety and replaced with the following: 
 “(10) to
(a) cure any ambiguity or correct or supplement any inconsistent or otherwise defective provision contained in the Indenture or (b) make any provision with respect to matters or questions arising under this Indenture that the Company may
deem necessary or desirable and that shall not be inconsistent with provisions of the Indenture.” 
 Section 6.02. Modification
and Amendment with Consent of Noteholders 
 Section 902 of the Base Indenture shall be applicable to the Notes. In addition, as
contemplated by Sections 301 and 902 of the Base Indenture, no supplemental indenture shall, without the consent of the Holder of each Outstanding Note affected thereby: 
 (a) make any change that affects the right of any Holder to convert Notes into shares of the Company’s Common Stock or reduce the
number of shares of Common Stock receivable upon conversion pursuant to the terms of the Indenture; 
 (b) change the
Company’s obligation to repurchase any Notes upon a Fundamental Change in a manner adverse to the Holders after the occurrence of a Fundamental Change. 
 Section 6.03. Effect of Supplemental Indentures Upon the execution of any supplemental indenture under this Article, the Base Indenture and this Supplemental Indenture shall be modified in accordance

 15 








 Section 6.04. Article Nine of Base Indenture Except as amended by this Article VI, all
of the provisions of Article Nine of the Base Indenture shall be applicable to the Notes. 
 ARTICLE VII 
 CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE 
 Section 7.01. Consolidation, Merger and Sale of Assets. 
 Section 801 of the Base Indenture
is deleted in its entirety and replaced with the following: 
 Section 801. Consolidation, Merger and Sale of Assets. The Company will
not, in a single transaction or a series of related transactions, consolidate with or merge with or into any other Person, or sell, convey, transfer or lease its property and assets substantially as an entirety to another Person, unless: 

 

	 	(1)	either (a) the Company shall be the continuing corporation or (b) the resulting, surviving or transferee person (if other than the Company) shall be a corporation or
limited liability company organized and existing under the laws of the United States of America, any State thereof or the District of Columbia (the “Successor Company”), and such Successor Company shall expressly assume, by an
indenture supplemental to the Indenture in a form reasonably satisfactory to the Trustee, executed and delivered to the Trustee, and a supplemental agreement, all the obligations of the Company under the Notes and the Indenture;


  

	 	(2)	immediately after giving effect to such transaction, no default or Event of Default has occurred and is continuing; 

  

	 	(3)	if as a result of such transaction the Notes become convertible into common stock or other securities issued by a third party, such third party fully and unconditionally guarantees
all obligations of the Company or the Successor Company, as the case may be, under the Notes and the Indenture; and 

  

	 	(4)	the Company shall have delivered to the Trustee any Officers’ Certificate and Opinion of Counsel required by Section 803 of the Base Indenture. 


ARTICLE VIII 
 CONVERSION OF
NOTES 
 Section 8.01. Conversion Privilege 
 (a) Upon compliance with the provisions of this Article VIII, a Holder of Notes shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000
principal amount or an integral multiple thereof) of such 

  

 16 








 
Note at any time prior to the Close of Business on the scheduled Business Day immediately preceding the Maturity Date at a rate (the “Conversion
Rate”) of 63.4417 shares of Common Stock (subject to adjustment by the Company as provided in Section 8.04) per $1,000 principal amount of Notes (the “Conversion Obligation”). 
 (b) (1) If and only to the extent a Noteholder elects to convert Notes prior to the Maturity Date in connection with a transaction described in clause
(a) or (d) of the definition of Fundamental Change pursuant to which 10% or more of the consideration for the Common Stock (other than cash payments for fractional shares and cash payments made in respect of dissenters’ appraisal
rights) in such transaction consists of cash or securities (or other property) that are not shares of common stock traded or scheduled to be traded immediately following such transaction on a U.S. national securities exchange, then the Conversion
Rate applicable to each $1,000 principal amount of Notes so converted shall be increased by an additional number of shares of Common Stock (the “Additional Shares”) as described below. The Company shall notify Holders of the
anticipated effective date of a Fundamental Change meeting the conditions of this Section 8.01(b) at least 20 calendar days prior to the anticipated effective date of such Fundamental Change. Settlement of Notes tendered for conversion to which
Additional Shares shall be added to the Conversion Rate as provided in this subsection shall be settled pursuant to Section 8.02 below, as applicable. For purposes of this Section 8.01(b), a conversion of Notes shall be deemed to be
“in connection with” a Fundamental Change to the extent that the related conversion notice is received by the Conversion Agent following the effective date of the Fundamental Change but before the Close of Business on the Business Day
immediately preceding the related Fundamental Change Repurchase Date. Such conversion notice shall indicate that the Holder of Notes has elected to convert Notes in connection with a Fundamental Change; provided, however, that the
failure to so indicate shall not in any way affect the Conversion Obligation or the right of such Holder to receive Additional Shares in connection with such conversion. 
 (2) The number of Additional Shares by which the Conversion Rate will be increased shall be determined by reference to the table attached as Schedule A hereto, based on the date on which the Fundamental Change
occurs or becomes effective (the “Effective Date”), and the Stock Price; provided, that if the Stock Price is between two Stock Price amounts in the table attached as Schedule A hereto or the Effective Date is between two
Effective Dates in the table attached as Schedule A hereto, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Price amounts and the
two dates, as applicable, based on a 360-day year; provided further that if (x) the Stock Price is in excess of $140.00 per share of Common Stock (subject to adjustment in the same manner as set forth in Section 8.04), no Additional
Shares will be added to the Conversion Rate, and (y) the Stock Price is less than $12.125 per share of Common Stock (subject to adjustment in the same manner as set forth in Section 8.04), no Additional Shares will be added to the
Conversion Rate. Notwithstanding the foregoing, in no event will the total number of shares of Common Stock issuable upon conversion exceed 82.4742 per $1,000 principal amount of Notes (subject to adjustment in the same manner as set forth in
Section 8.04). 
  

 17 








 The number of Additional Shares within the table in Schedule A hereto shall be adjusted in the same
manner as and as of any date on which the Conversion Rate of the Notes is adjusted as set forth in Section 8.04 (other than by operation of an adjustment to the Conversion Rate by adding Additional Shares). The Stock Prices set forth in the
first row of the table attached as Schedule A hereto (i.e., the column headers) shall be simultaneously adjusted as of any date on which the Conversion Rate of the Notes is adjusted. The adjusted Stock Prices shall equal the Stock Prices
applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate in effect immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the
Conversion Rate as so adjusted. 
 Section 8.02. Conversion Procedures (a) Each Security shall be convertible at the office of
the Conversion Agent and, if applicable, in accordance with the procedures of the Depositary. 
 (b) In order to exercise the conversion
privilege with respect to any interest in a Global Note, the Holder must complete the appropriate instruction form for conversion pursuant to the Depositary’s book-entry conversion program, furnish appropriate endorsements and transfer
documents if required by the Company or the Conversion Agent, pay the funds, if any, required by Section 4.01(b) and all taxes or duties, if any, for which the Holder is responsible pursuant to Section 1605 of the Base Indenture, and the
Conversion Agent must be informed of the conversion in accordance with the customary practice of the Depositary. In order to exercise the conversion privilege with respect to any certificated Notes, the Holder of any such Notes to be converted, in
whole or in part, shall: 
 (i) complete and manually sign the conversion notice provided on the back of the Note and attached
hereto as Exhibit B (the “Conversion Notice”) or a facsimile of the Conversion Notice; 
 (ii) deliver the
completed Conversion Notice, which is irrevocable, and the Note to the Conversion Agent; 
 (iii) if required, furnish
appropriate endorsements and transfer documents; 
 (iv) if required, pay the funds required by Section 4.01(b); and

 (v) if required, pay all taxes or duties pursuant to Section 1605 of the Base Indenture. 
 The date on which the Holder satisfies all of the applicable requirements set forth in this Section 8.02(b) is the “Conversion
Date.” The Conversion Agent will, as promptly as possible, and in any event within two (2) Business Days of the receipt thereof, provide the Company with notice of any conversion by a Holder of the Securities. 
 (c) Each Conversion Notice shall state the name or names (with address or addresses) in which any certificate or certificates for shares of Common Stock
which shall be issuable upon such conversion shall be issued. All such Notes surrendered for conversion shall, unless the shares of Common Stock issuable upon conversion are to be issued in the same name as the registration of such Notes, be duly
endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or his duly authorized attorney. 
  

 18 








 (d) In case any Notes of a denomination greater than $1,000 shall be surrendered for partial conversion,
the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Notes so surrendered, without charge, new Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the
surrendered Notes. 
 Each conversion shall be deemed to have been effected as to any such Notes (or portion thereof) surrendered for conversion immediately
prior to the Close of Business on the relevant Conversion Date. The person in whose name the certificate or certificates for the number of shares of Common Stock that shall be issuable upon such conversion shall become the holder of record of such
shares of Common Stock as of the Close of Business on such Conversion Date. Notwithstanding the foregoing and anything contained in this Supplemental Indenture to the contrary, in no event shall a Holder be entitled to the benefit of a Conversion
Rate adjustment pursuant to the provisions of Article VIII hereof in respect of Notes surrendered for conversion if, by virtue of being deemed the record holder of the shares of Common Stock issuable upon such conversion pursuant to the foregoing
sentence, such Holder participates, as a result of being such holder of record, in the transaction or event that would otherwise give rise to such Conversion Rate adjustment to the same extent and in the same manner as holders of shares of Common
Stock generally. 
 (e) Upon the conversion of an interest in Global Notes, the Trustee (or other Conversion Agent appointed by the Company)
shall make a notation on such Global Notes as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Securities effected through any Conversion Agent other than the
Trustee. 
 (f) Notwithstanding the foregoing, a Note in respect of which a Holder has delivered a Fundamental Change Repurchase Notice
exercising such Holder’s option to require the Company to purchase such Note may be converted only if such Fundamental Change Repurchase Notice is withdrawn in accordance with Article IX hereof prior to the Close of Business on the
Fundamental Change Purchase Date. 
 Section 8.03. Payments Upon Conversion (a) Upon any conversion of any Notes, on the third
Business Day immediately following the Conversion Date, the Company shall deliver to the converting Holder a number of shares of Common Stock equal to (i) the aggregate principal amount of such Notes to be converted divided by $1,000,
multiplied by (ii) the Conversion Rate in effect as of such Conversion Date, together with any cash payment for any fractional share of Common Stock as described in this Section 8.03. 
 (b) [RESERVED] 
  

 19 








 (c) Notwithstanding anything to the contrary in the Indenture, upon the conversion of any Notes, the
Holder will not be entitled to receive any separate cash payment for accrued and unpaid interest (including Additional Interest), if any, except to the extent specified in Section 4.01. The Company’s delivery to the Holder of Common Stock
together with any cash payment for any fractional share of Common Stock into which a Note is convertible will be deemed to satisfy in full the Company’s obligation to pay the principal amount of the Notes so converted and accrued and unpaid
interest (including Additional Interest), if any, to, but not including, the Conversion Date. As a result, accrued and unpaid interest (including Additional Interest), if any, to, but not including, the Conversion Date will be deemed to be paid in
full rather than cancelled, extinguished or forfeited. 
 (d) The Company shall not issue fractional shares of Common Stock upon conversion
of Notes. If multiple Notes shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (or
specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share of Common Stock would be issuable upon the conversion of any Notes, the Company shall make payment therefor in cash in lieu of fractional shares of
Common Stock based on the Last Reported Sale Price on the relevant Conversion Date. 
 Section 8.04. 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 Common Stock, or effects a share split or share combination, then the Conversion Rate shall be adjusted based on the following formula: 
 

 
  

					
	where	  	
			
	CR ́	 	=	  	the Conversion Rate in effect immediately prior to the Opening of Business on the record date for such dividend or distribution or the effective date of such share split or combination, as the
case may be;
			
	CR0	 	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding the record date for such dividend or distribution or the effective date of such
share split or combination, as the case may be;
			
	OS0	 	=	  	the number of shares of Common Stock outstanding at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution or the
effective date of such share split or combination; and

  

 20 









					
			
	OS ́	 	=	  	the number of shares of Common Stock that would be outstanding immediately after giving effect to such dividend, distribution, share split or combination, as the case may be.

 Such adjustment shall become effective immediately prior to the Opening of Business on the record date for such
dividend or distribution or the effective date of such share split or combination, as the case may be. If any dividend or distribution of the type described in this Section 8.04(a) is declared but not so paid or made, or the outstanding shares
of Common Stock are not subdivided or combined, as the case may be, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, or subdivide or combine the
outstanding shares of Common Stock, as the case may be, to the Conversion Rate that would then be in effect if such dividend, distribution, subdivision or combination had not been declared. 
 (b) In case the Company shall issue to all or substantially all holders of its Common Stock any rights or warrants (other than rights issued pursuant to
a shareholders’ rights plan) entitling them for a period of not more than 45 days from the issuance date for such distribution to subscribe for or purchase shares of Common Stock, at a price per share less than the Last Reported Sale Price of
the Common Stock on the Trading Day immediately preceding the declaration date of such distribution, then the Conversion Rate shall be adjusted based on the following formula: 
 

 
  

					
	where	  	
			
	CR ́	 	=	  	the Conversion Rate in effect immediately prior to the Opening of Business on the record date for such distribution;
			
	CR0	 	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding the record date for such distribution;
			
	OS0	 	=	  	the number of shares of Common Stock outstanding at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Ex-Dividend Date for such distribution;
			
	X	 	=	  	the total number of shares of Common Stock issuable pursuant to such rights or warrants; and
			
	Y	 	=	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights or warrants, divided by the average of the Last Reported Sale Prices of Common Stock over the 10
consecutive Trading Day period ending on the Trading Day immediately preceding the record date for such distribution.

  

 21 








 Such adjustment shall be successively made whenever any such rights or warrants are issued and shall become effective
immediately prior to the Opening of Business on the record date for such distribution. If such rights or warrants are not so exercised prior to their expiration, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then
be in effect if such record date for such distribution had not been fixed. 
 In determining whether any rights or warrants entitle the
holder thereof to subscribe for or purchase shares of Common Stock at a price per share less than the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the declaration date of such distribution, and in determining
the aggregate offering price of such Common Stock, there shall be taken into account any consideration received by the Company for such rights or warrants and any amount payable on exercise or conversion thereof, where the value of such
consideration, if other than cash, shall be determined by the Board of Directors. 
 (c) In case the Company shall distribute shares of
Capital Stock, evidences of indebtedness or other assets or property to all or substantially all holders of its Common Stock (excluding dividends and distributions covered by Section 8.04(a), Section 8.04(b), Section 8.04(d), and
distributions described below in this Section 8.04(c) with respect to Spin-Offs (as defined below)) (any of such shares of Capital Stock, evidences of indebtedness or other asset or property hereinafter in this Section 8.04(c) called
the “Distributed Property”), then, in each such case the Conversion Rate shall be adjusted based on the following formula: 
 

 
  

					
	where	  	
			
	CR ́	 	=	  	the Conversion Rate in effect immediately prior to the Opening of Business on the record date for such distribution;
			
	CR0	 	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding 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 ending on the Trading Day immediately preceding the record date for such
distribution; and
			
	FMV	 	=	  	the fair market value (as determined by the Board of Directors or a committee thereof) of the Distributed Property distributed with respect to each outstanding share of Common Stock as of the
Opening of Business on the record date for such distribution.

 Such adjustment shall become effective immediately prior to
the Opening of Business on the record date for shareholders entitled to receive such distribution; provided that (1) if the then fair market value (as so determined) of the portion of the Distributed Property so distributed applicable to one
share of Common Stock is equal to or greater than SP0 as set forth above or (2) if SP0
 exceeds the fair 

  

 22 








 
market value of the Distributed Property by less than $1.00, in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder
shall have the right to receive, for each $1,000 principal amount of Notes upon conversion, the amount of Distributed Property such Holder would have received had such Holder converted such Notes immediately prior to the record date for determining
the shareholders of the Company entitled to receive the Distributed Property. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such
dividend or distribution had not been declared. If the Board of Directors determines the fair market value of any distribution for purposes of this Section 8.04(c) by reference to the actual or when issued trading market for any securities, it
must in doing so consider the prices in such market over the same period used in determining SP0 above. 
 With respect to an adjustment pursuant to this Section 8.04(c) where there has been a payment of a dividend or other distribution on the Common
Stock in shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company that are listed on a national or regional securities exchange (a “Spin-Off”),
then the Conversion Rate will be increased based on the following formula: 
 

 
  

					
	where	 		  	
			
	CR ́	 	=	  	the Conversion Rate in effect immediately prior to the Opening of Business on the record date for the Spin-Off;
			
	CR0	 	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding the record date for the Spin-Off;
			
	FMV	 	=	  	the average of the Last Reported Sale Prices of the Capital Stock or other similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock over the first
ten consecutive Trading Day period immediately following, and including, the third Trading Day after the record date for such Spin-Off (such period, the “Valuation Period”); and
			
	MP0	 	=	  	the average of the Last Reported Sale Prices of Common Stock over the Valuation Period.

 Such adjustment shall occur immediately after the Opening of Business on the day after the last day of the
Valuation Period but will be given effect as of the Opening of Business on the record date for the Spin-Off; provided that in respect of any conversion within the ten Trading Days following any Spin-Off, references within this
Section 8.04(c) to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between such Spin-Off and the Conversion Date in determining the applicable Conversion Rate. Because the Company will make
the adjustment to the Conversion Rate at the end of the Valuation 

  

 23 








 
Period with retroactive effect, the Company will delay the settlement of any Notes where the final day of the related observation period occurs during the
Valuation Period. In such event, the Company will deliver shares of Common Stock (based on the adjusted Conversion Rate) on the third Business Day following the last day of the Valuation Period. 
 Rights or warrants distributed by the Company to all holders of Common Stock, entitling the holders thereof to subscribe for or purchase Capital Stock
(either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such Common Stock; (ii) are not
exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 8.04(c) (and no adjustment to the Conversion Rate under this
Section 8.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be
made under this Section 8.04(c). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Supplemental Indenture, are subject to events, upon the occurrence of which such rights or
warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new
rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or
any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 8.04
was made, (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect
to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming
such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or been terminated without exercise
by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued. 
 For purposes of this
Section 8.04(c) and Section 8.04(a) and Section 8.04(b), any dividend or distribution to which this Section 8.04(c) is applicable that also includes a dividend or distribution of Common Stock to which Section 8.04(a) applies
or a dividend or distribution of rights or warrants to subscribe for or purchase Common Stock to which Section 8.04(a) or Section 8.04(b) applies (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences
of indebtedness, assets or shares of Capital Stock other than such Common Stock or rights or warrants to which this Section 8.04(c) applies, and any Conversion Rate adjustment required by this Section 8.04(c) with respect to such dividend
or distribution shall then be made, immediately followed by (2) a dividend or distribution of such Common Stock or such rights or warrants (and any further Conversion Rate adjustment required by Section 8.04(a) and Section 8.04(b)
with respect to such dividend or distribution shall then be made), except (A) the record date of 

  

 24 








 
such dividend or distribution shall be substituted as “the record date” and “the date fixed for such determination” within the meaning of
Section 8.04(a) and Section 8.04(b) and (B) any Common Stock included in such dividend or distribution shall not be deemed outstanding “at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Ex-Dividend
Date for such dividend or distribution or the effective date of such share split or combination” within the meaning of Section 8.04(a) or “at 5:00 p.m., New York City time, on the Trading Day immediately preceding the Ex-Dividend Date
for such distribution” within the meaning of Section 8.04(b). 
 (d) In case the Company shall pay any cash dividends or
distributions paid exclusively in cash to all or substantially all holders of Common Stock (other than dividends or distributions to which Section 8.06 applies), then the Conversion Rate will be increased based on the following formula:

 

 
  

					
	where	  	
			
	CR ́	 	=	  	the Conversion Rate in effect immediately prior to the Opening of Business on the record date for such dividend or distribution;
			
	CR0	 	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time, on the Trading Day immediately preceding 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 ending on the Trading Day immediately preceding the record date for such
distribution;
			
	C	 	=	  	the amount in cash per share that the Company distributes to holders of Common Stock.

 Such adjustment shall become effective immediately prior to the Opening of Business on the record date for such
dividend or distribution. 
 For the avoidance of doubt, for purposes of this Section 8.04(d), in the event of any reclassification of
the Common Stock, as a result of which the Notes become convertible into more than one class of Common Stock, if an adjustment to the Conversion Rate is required pursuant to this Section 8.04(d), references in this Section to one share of
Common Stock or Last Reported Sale Price of one share of Common Stock shall be deemed to refer to a unit or to the price of a unit consisting of the number of shares of each class of Common Stock into which the Notes are then convertible equal to
the number of shares of such class issued in respect of one share of Common Stock in such reclassification. The above provisions of this paragraph shall similarly apply to successive reclassifications. 
  

 25 








 (e) In case the Company or any of its Subsidiaries makes a payment in respect of a tender offer or
exchange offer for Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Last Reported Sale Price 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, then the Conversion Rate shall be increased based on the following formula: 
 

 
  

					
	where	  	
			
	CR ́	 	=	  	the Conversion Rate in effect immediately prior to the Opening of Business on the Trading Day next succeeding the date such tender offer or exchange offer expires;
			
	CR0	 	=	  	the Conversion Rate in effect at 5:00 p.m., New York City time on the day such tender offer or exchange offer expires;
			
	AC	 	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors or a committee thereof) paid or payable for shares purchased in such tender or exchange
offer;
			
	SP ́	 	=	  	the average of the Last Reported Sale Prices of Common Stock over the ten consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the date such tender or
exchange offer expires (the “Averaging Period”);
			
	OS ́	 	=	  	the number of shares of Common Stock outstanding immediately after the Close of Business on the date such tender or exchange offer expires (after giving effect to such tender offer or exchange
offer); and
			
	OS0	 	=	  	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to such tender offer or exchange
offer).

 Such adjustment shall become effective immediately prior to the Opening of Business on the day following the last
day of the Averaging Period, but will be given effect as of the Opening of Business on the Trading Day next succeeding the date such tender offer or exchange offer expires. Because the Company will make the adjustment to the Conversion Rate at the
end of the Averaging Period with retroactive effect, the Company will delay the settlement of any Notes where the final day of the related observation period occurs during the Averaging Period. In such event, the Company will deliver shares of
Common Stock, if any, (based on the adjusted Conversion Rate) on the third Business Day immediately following the last day of the Averaging Period. 
  

 26 








 (f) For purposes of this Section 8.04 the term “record date” shall mean, with
respect to any dividend, distribution or other transaction or event in which the holders of shares of Common Stock have the right to receive any cash, securities or other property or in which the shares of Common Stock (or other applicable security)
is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of shareholders of the Company entitled to receive such cash, securities or other property (whether such date is fixed by the
Board of Directors or by statute, contract or otherwise). 
 (g) All calculations and
other determinations under this Article VIII shall be made by the Company in accordance with Section 10.14 hereof and shall be made to the nearest cent or to the nearest one-ten thousandth ( 1/10,000) of a share, as the case may be. No adjustment shall be made for the Company’s issuance of Common Stock or any securities convertible into or exchangeable
for Common Stock, or the right to purchase Common Stock or such convertible or exchangeable securities, other than as provided in this Section 8.04. No adjustment shall be made to the Conversion Rate unless such adjustment would require a
change of at least 1% in the Conversion Rate then in effect at such time. The Company shall carry forward any adjustments that are less than 1% of the Conversion Rate, take such carried-forward adjustments into account in any subsequent adjustment,
and make such carried forward adjustments, regardless of whether the aggregate adjustment is less than 1%, (i) annually on the anniversary of the first date of issue of the Notes and otherwise (ii)(1) five Business Days prior to the first day
of the conversion period related to the Maturity of the Notes (whether at Stated Maturity or otherwise) or (2) prior to any Fundamental Change Repurchase Date, unless such adjustment has already been made. 
 (h) 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. The Trustee and Conversion Agent may conclusively rely on the accuracy of the
Conversion Rate adjustment provided by the Company. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate
and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the
adjusted Conversion Rate and the date on which each adjustment becomes effective and shall issue a press release containing the relevant information and make the information available on the Company’s website or through another public medium as
the Company may use at such time. 
 (i) For purposes of this Section 8.04, the number of shares of Common Stock at any time outstanding
shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. 
 Section 8.05. Shares to be Fully Paid Subject to Section 8.03(d), the Company shall provide, free from preemptive rights, sufficient
Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion. 
  

 27 








 Section 8.06. Effect of Reclassification, Consolidation, Merger or Sale

 (a) If the Company: 
 (i) reclassifies or changes its Common Stock (other than changes resulting from a subdivision or combination); or 
 (ii) consolidates or merges with or into any person or sells, leases, transfers, conveys or otherwise disposes of all or substantially all of its assets and those of its Subsidiaries taken as a whole to another Person; 
 and in either case holders of Common Stock receive stock, other securities or other property or assets (including cash or any combination thereof) with respect to or in
exchange for their Common Stock (any such event, a “Merger Event”), then from and after the effective date of such Merger Event, 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 at and after the effective time of such Merger Event, each outstanding Note will, without the
consent of Holders of the Notes, become convertible in accordance with the Indenture into the consideration the holders of Common Stock received in such reclassification, change, consolidation, merger, sale, lease, transfer, conveyance or other
disposition (such consideration, the “Reference Property”). If the transaction causes the Common Stock to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of
shareholder election), the Reference Property into which the Notes will become convertible will be deemed to be the kind and amount of consideration elected to be received by a majority of Common Stock which voted for such election (if electing
between two types of consideration) or a plurality of Common Stock which voted for such an election (if electing between more than two types of consideration), as the case may be. The Company shall not become a party to any such Merger Event unless
its terms are consistent with this Section 8.06 in all material respects. 
 (b) The Company shall cause notice of the execution of such
supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the register of the Notes maintained by the Security Registrar, within 20 days after execution thereof. Failure to deliver such notice shall not
affect the legality or validity of such supplemental indenture. The above provisions of this Section 8.06 shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. If this
Section 8.06 applies to any Merger Event, Section 8.04 shall not apply. 
 Section 8.07. Intentionally Omitted

 Section 8.08. Intentionally Omitted 
  

 28 








 Section 8.09. 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 8.04; or 
 (b) the Company shall authorize the granting to all of the holders of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants; 
 (c) of any reclassification of Common Stock (other than a subdivision or combination of the 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 shareholders 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 Noteholder at his address appearing on the Security Register as
promptly as possible but in any event at least thirty (30) days prior to the applicable date specified in clause (x) or (y) below, as the case may be, a notice stating (x) the date on which a record is to be taken for the
purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined, or
(y) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record
shall be entitled to convert 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 8.10. Shareholder Rights Plans To the extent that any future shareholders’ rights plan adopted by the Company is in effect upon
conversion of the Notes into Common Stock, Holders shall receive, in addition to any Common Stock issuable upon such conversion, the rights under the applicable rights agreement unless the rights have separated from the Common Stock at the time of
conversion of the Notes, in which case, the Conversion Rate will be adjusted as if the Company distributed to all holders of its Common Stock shares of its Capital Stock, evidences of indebtedness or assets as described in Section 8.03(c),
subject to readjustment in the event of the expiration, termination or redemption of such rights. If, and only if, the Holders receive rights under such shareholders’ rights plan as described in the preceding sentence upon conversion of their
Notes, then no other adjustment pursuant to this Article VIII shall be made in connection with such shareholders’ rights plan. 
  

 29 








 ARTICLE IX 
 REPURCHASE OF NOTES AT OPTION OF HOLDERS 
 Section 9.01. Repurchase of Securities at Option
of the Holder on Specified Dates The provisions of Article Thirteen of the Base Indenture shall not be applicable to the Notes. 
 Section 9.02. Repurchase at Option of Holders Upon a Fundamental Change 
 (a) If a Fundamental Change occurs at any
time prior to the Maturity Date, then each Noteholder shall have the right, at such Holder’s option, to require the Company to repurchase all of such Holder’s Notes or any portion thereof that is a multiple of $1,000 principal amount, for
cash on or after the Close of Business on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than twenty (20) calendar days and not more than thirty-five (35) calendar days after
the date of the Fundamental Change Company Notice (as defined below) at a repurchase price equal to 100% of the principal amount thereof, together with accrued and unpaid interest thereon (including Additional Interest, if any) to, but excluding,
the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”); provided, however, if the Fundamental Change Repurchase Date is after a Record Date and on or prior to the corresponding Interest Payment Date, the
accrued and unpaid interest (including Additional Interest, if any) will be paid on the Fundamental Change Repurchase Date to the Holder of record on the Record Date. 
 Repurchases of Notes under this Section 9.02 shall be made, at the option of the Holder thereof, upon: 
 (i) delivery to the Trustee (or other Paying Agent appointed by the Company) by a Holder of a duly completed notice (the “Fundamental Change Repurchase Notice”) in the form set forth on the reverse of
the Note at any time prior 5:00 p.m., New York City Time, on the Fundamental Change Repurchase Date; and 
 (ii) delivery
or book-entry transfer of the Notes to the Trustee (or other Paying Agent appointed by the Company) at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements) at the Corporate Trust Office of
the Trustee (or other Paying Agent appointed by the Company) in the Borough of Manhattan, such delivery 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 9.02 only if the Note so delivered to the Trustee (or other Paying Agent appointed by the Company) shall conform in all respects to the description thereof in the related Fundamental
Change Repurchase Notice. 
 The Fundamental Change Repurchase Notice shall state: 
 (A) if certificated, the certificate numbers of Notes to be delivered for repurchase; 
  

 30 








 (B) the portion of the principal amount of Notes to be repurchased, which must be $1,000
or an integral multiple thereof; 
 (C) that the Notes are to be repurchased by the Company pursuant to the applicable
provisions of the Notes and the Indenture; and 
 (D) if such Fundamental Change Repurchase Notice is delivered prior to the
occurrence of a Fundamental Change pursuant to a definitive agreement giving rise to a Fundamental Change, that the Holder acknowledges that the Company’s offer is conditioned on the occurrence of such Fundamental Change. 
 provided, however, that if the Notes are not in certificated form, the Fundamental Change Repurchase Notice must comply with appropriate procedures of the
Depositary. 
 Any repurchase by the Company contemplated pursuant to the provisions of this Section 9.02 shall be consummated by the
delivery of the consideration to be received by the Holder promptly following the later of the Fundamental Change Repurchase Date and the time of the book-entry transfer or delivery of the Note. 
 The Trustee (or other Paying Agent appointed by the Company) shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase
Notice or written notice of withdrawal thereof in accordance with the provisions of Section 9.02(c). 
 Any Note that is to be
repurchased only in part shall be surrendered to the Trustee (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by the Holder
thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Note without service charge, a new Note or Notes, containing identical terms
and conditions, each in an authorized denomination in aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal of the Note so surrendered. 
 (b) At any time following the Company entering into a definitive agreement that, if consummated,
would give rise to a Fundamental Change, but in any event not later than the fifth (5th) calendar day after the occurrence of a Fundamental
Change, the Company shall provide to all Holders of record of the Notes as of the date of the Fundamental Change Company Notice at their addresses shown in the Security Register (and to beneficial owners to the extent required by applicable law) and
the Trustee and Paying Agent a written notice (the “Fundamental Change Company Notice”) of the occurrence of such Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. Such mailing
shall be by first class mail. Simultaneously with providing such Fundamental Change Company Notice, the Company shall publish a notice containing the information included therein once in a newspaper of general circulation in The City of New York or
publish such information on the Company’s website or through such other public medium as the Company may use at such time. 
  

 31 








 Each Fundamental Change Company Notice shall specify: 
 (i) the events causing the Fundamental Change; 
 (ii) the date of the Fundamental Change; 
 (iii) if such Fundamental Change Company Notice is delivered prior to the occurrence of a Fundamental Change pursuant to a definitive agreement giving rise to a Fundamental Change, that the offer is conditioned on the
occurrence of such Fundamental Change; 
 (iv) that the Holder must exercise the repurchase right prior to the Close of
Business on the Fundamental Change Repurchase Date; 
 (v) the Fundamental Change Repurchase Price; 
 (vi) the Fundamental Change Repurchase Date; 
 (vii) the name and address of the Paying Agent and the Conversion Agent; 
 (viii) the
applicable Conversion Rate and any adjustments to the applicable Conversion Rate; 
 (ix) that the Notes with respect to which
a Fundamental Change Repurchase Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of the Indenture; and 
 (x) the procedures that Holders must follow to require the Company to repurchase their 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 9.02. 
 (c) A Fundamental Change Repurchase Notice may be
withdrawn by delivering a written notice of withdrawal to the Paying Agent in accordance with the Fundamental Change Company Notice at any time prior to the 5:00 p.m., New York City time, on the Fundamental Change Repurchase Date, specifying:

 (i) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted; 
 (ii) the principal amount, if any, of such Notes that remains subject to the original Fundamental Change Repurchase Notice, which portion
must be in principal amounts of $1,000 or an integral multiple of $1,000; and 
  

 32 








 (iii) if certificated Notes have been issued, the certificate numbers of the withdrawn
Notes; and 
 provided, however, that if the Notes are not in certificated form, the notice must comply with appropriate procedures of the
Depositary. The Paying Agent will promptly return to the respective Holders thereof any certificated Notes with respect to which a Fundamental Change Repurchase Notice has been withdrawn in compliance with the provisions of this
Section 9.02(c). If the Notes are not in certificated form, such return must comply with the appropriate procedures of the Depositary. If a Fundamental Change Repurchase Notice is given and then subsequently withdrawn in accordance with this
Section 9.02(c), then the Company shall not be obligated to repurchase any Notes listed in such Fundamental Change Repurchase Notice. 
 (d) On or prior to 11:00 a.m. (local time in The City of New York) on the Business Day following the Fundamental Change Repurchase Date, the Company will deposit with the Trustee (or other Paying Agent appointed by the Company) or if
the Company is acting as its own Paying Agent, set aside, segregate and hold in trust in accordance with the Indenture an amount of money or securities sufficient to repurchase as of the Fundamental Change Repurchase Date all of the Notes to be
repurchased as of such date at the Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn) prior
to the Close of Business on the Fundamental Change Repurchase Date will be made promptly after the later of (x) the Fundamental Change Repurchase Date with respect to such Note (provided the Holder has satisfied the conditions to the
payment of the Fundamental Change Repurchase Price in this Section 9.02), and (y) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the
manner required by this Section 9.02 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Security Register (in the case of certificated Notes) by wire transfer of immediately
available funds to the account of the Depositary or its nominee (if the Notes are not in certificated form). The Trustee shall, promptly after such payment return to the Company any funds in excess of the Fundamental Change Repurchase Price.

 (e) If the Trustee (or other Paying Agent appointed by the Company) holds money or securities sufficient to repurchase as of the
Fundamental Change Repurchase Date all the Notes or portions thereof that are to be purchased as of the Business Day following the Fundamental Change Repurchase Date, then on and after the Fundamental Change Repurchase Date (i) such Notes will
cease to be Outstanding, (ii) interest (including Additional Interest, if any) will cease to accrue on such Notes, whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent, as
the case may be, and (iii) all other rights of the Holders of such Notes will terminate other than the right to receive the Fundamental Change Repurchase Price upon delivery or transfer of such Notes. 
 Section 9.03. No Payment Following Acceleration of the Notes. 
 There shall be no purchase of any Notes pursuant to this Article IX if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded on or prior to the Fundamental Change
Purchase Date. The Trustee (or other Paying Agent appointed by the Company) will promptly return to the respective Holders thereof any certificated Notes held by it following 

  

 33 








 
acceleration of the Notes and shall deem canceled any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary,
in which case, upon such return and cancellation, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 
 Section 9.04. Compliance with Tender Offer Rules. 
 In connection with any offer to purchase
Notes under Section 9.02 hereof, the Company shall, in each case if required, (a) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable, (b) file a Schedule TO or any
other required schedule under the Exchange Act and (c) otherwise comply with all federal and state securities laws so as to permit the rights and obligations under Section 9.02 to be exercised in the time and in the manner specified in
Section 9.02.

 ARTICLE XI 
 GUARANTEES 
 Section 11.01. Guarantee Subject to this Article XI, each of the Guarantors hereby, jointly and severally, unconditionally guarantees on
an unsecured, unsubordinated basis, to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Supplemental Indenture or the Base
Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: 
 (i) the principal of, premium and
Additional Interest, if any, and interest on, the Notes will be promptly paid in full when due, whether at maturity, by acceleration or otherwise, and interest on the overdue principal and interest on the Notes, if any, if lawful, and all other
obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 
 (ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid
in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. 
  

 36 








 Failing payment when due of any amount so guaranteed or any performance so guaranteed for any whatever
reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 
 (b) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of this
Supplemental Indenture or the Base Indenture, the Notes, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the
Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims
with a court in the event of bankruptcy or insolvency of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Guarantee will not be discharged except by complete
performance of the obligations contained in the Notes and the Indenture. 
 (c) If any Holder or the Trustee is required by any court or
otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid either to the Trustee or such Holder, this Guarantee, to
the extent theretofore discharged, shall be reinstated in full force and effect. 
 (d) Each Guarantor agrees that it shall not be entitled
to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations under the Notes guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the
one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Five of the Base Indenture for the purposes of this Guarantee, notwithstanding
any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article Five of the Base
Indenture, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for purposes of this Guarantee. The Guarantors will have the right to seek contribution from any other Guarantor, or the Company, as
the case may be, so long as the exercise of such right does not impair the rights of the Holders under the Guarantee. 
 Section 11.02.
Limitation on Guarantor Liability Each Guarantor, and by its acceptance of the Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer,
fraudulent conveyance or fraudulent obligation for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Guarantee. To effectuate
the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor shall be limited to the maximum amount that shall, after giving effect to such maximum amount and all other
contingent and fixed liabilities of such 

  

 37 








 
Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contributions from or payments made by or on
behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article XI that are relevant under such laws, result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent transfer,
fraudulent conveyance or fraudulent obligation. 
 Section 11.03. Execution and Delivery of Guarantees To evidence its Guarantee
set forth in Section 11.01 hereof, each Guarantor hereby agrees that this Supplemental Indenture shall be executed on behalf of such Guarantor by one of its authorized officers. 
 (b) Each Guarantor hereby agrees that its Guarantee set forth in Section 11.01 hereof shall remain in full force and effect notwithstanding the
absence of the endorsement of any notation of such Guarantee. 
 (c) If an officer whose signature is on this Supplemental Indenture no
longer holds that office at the time the Trustee authenticates the Note, the Guarantee shall be valid nevertheless. 
 (d) The delivery of
any Note by the Trustee, after the authentication thereof hereunder, shall constitute delivery of the Guarantee set forth in the Indenture on behalf of the Guarantors. 
 (e) If required by Section 4.04 hereof, the Company shall cause any Subsidiary that is not a Guarantor to comply with the provisions of Section 4.04 hereof and this Article XI, to the extent applicable.

 Section 11.04. Contribution Each Guarantor that makes a payment or distribution under its Guarantee shall be entitled to
contribution from any other Guarantor or the Company, as the case may be. 
 Section 11.05. Releases The Guarantee issued by any
Guarantor shall be automatically and unconditionally released and discharged upon: 
 (a) any sale, exchange or transfer to any Person (other
than an Affiliate of the Company) of (i) the Capital Stock of such Guarantor so that such Guarantor is no longer a Subsidiary of the Company or (ii) all or substantially all the assets of such Guarantor; 
 (b) the release or discharge of the guarantee which resulted in the creation of such Guarantee, except a discharge or release by or as a result of
payment under such guarantee; or 
 (c) the release or discharge of any and all guarantees of all other unsecured indebtedness of the Company
provided by such Guarantor to the holders of other unsecured indebtedness (including any deemed release upon payment in full of all obligations under such other unsecured indebtedness); provided, however, to the extent that any Wholly
Owned Domestic Subsidiary of the Company provides a guarantee of any unsecured indebtedness of the Company in the future, such Wholly Owned Domestic Subsidiary shall be required to guarantee the Notes in accordance with Section 4.04 hereof.

  

 38 








 Provided, in each case, that such release or discharge shall not become effective until the receipt by the Trustee
of an Officers’ Certificate stating that all conditions precedent to the release and discharge of the Guarantee have been complied with.

 This Security shall bear interest at the rate of 4.00% per year from June 5, 2009, or from the most recent date to which interest had been paid
or provided. Except as otherwise provided in the Indenture, interest is payable semi-annually in arrears on each June 15 and December 15, commencing December 15, 2009, to Holders of record at the Close of Business on the preceding
June 1 and December 1, respectively. Interest payable on each Interest Payment Date shall equal the amount of interest accrued from, and including the immediately preceding Interest Payment Date (or from and including June 5, 2009, if

Date. Notwithstanding the foregoing, payment of interest in respect of Securities held in global form shall be made in accordance with procedures required by the Depositary. 
 Reference is made to the further provisions of this Security set forth on the reverse hereof, including, without limitation, provisions giving the Holder
of this Security the right to convert this Security into Common Stock on the terms and subject to the limitations referred to on the reverse hereof and as more fully specified in the Indenture. Such further provisions shall for all purposes have the

 [FORM OF REVERSE OF NOTE] 
 MasTec, Inc. 
 4.00% Senior Convertible Notes due 2014 
 This Security is one of a duly authorized issue of Securities of the Company, designated as its 4.00% Senior Convertible Notes due 2014 (herein called
the “Securities”), issued under and pursuant to an Indenture dated as of June 5, 2009 (herein called the “Base Indenture”), as supplemented by the First Supplemental Indenture, dated as of June 5, 2009 (as
so supplemented, herein called the “Indenture”), between the Company, the Guarantors listed in Schedule B to the Supplemental Indenture and U.S. Bank National Association (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 Guarantors and the Holders of the
Securities. Additional Securities may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. Capitalized terms used but not defined in this Security shall have the meanings ascribed to them in
the Indenture. 
 The Company’s obligations under this Security are fully and unconditionally guaranteed, jointly and severally, by the
Guarantors. 
 In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of and interest
on all Securities may be declared, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture. 
 Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase
Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Security to a Paying Agent to collect such payments in respect of the Security. The Company will pay cash amounts in money of the United States
that at the time of payment is legal tender for payment of public and private debts. 
 The Indenture contains provisions permitting the
Company and the Trustee in certain circumstances, without the consent of the Holders of the Securities, and in other circumstances, with the consent of the Holders of not less than a majority in principal amount of the Securities at the time
Outstanding, evidenced as in the Indenture provided, 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 Securities; provided, however, that no such supplemental indenture shall make any of the changes set forth in Section 6.02 of the Supplemental Indenture and Section 902 of the Base
Indenture, without the consent of each Holder of an Outstanding Security affected thereby. It is also provided in the Indenture that, prior to any declaration accelerating the maturity of the Securities, the Holders of a majority in principal amount
of the Securities at the time Outstanding may on behalf of the Holders of all of the Securities waive any past default or Event of Default under the Indenture and its consequences except as provided in the Indenture. Any such consent or waiver by
the Holder of this Security (unless revoked as provided in the 

  

 Exh. A-6 








 
Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Security and any Securities which may be issued in
exchange or substitution hereof, irrespective of whether or not any notation thereof is made upon this Security or such other Securities. 
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and accrued and unpaid interest on
this Security at the place, at the respective times, at the rate and in the lawful money herein prescribed. 
 The Securities are issuable in
registered form without coupons in denominations of $1,000 principal amount and integral multiples thereof. 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 or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities (except as otherwise
provided in the Base Indenture), Securities may be exchanged for a like aggregate principal amount of Securities of other authorized denominations. 
 The Securities are not subject to redemption and will not be entitled to the benefit of any sinking fund. 
 Upon the occurrence of
a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company to repurchase all of such Holder’s Securities or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) in
accordance with the provisions of the Indenture on the Fundamental Change Repurchase Date at a price equal to 100% of the principal amount of the Securities such holder elects to require the Company to repurchase, together with accrued and unpaid
interest (including Additional Interest, if any) to but excluding the Fundamental Change Repurchase Date, except as otherwise provided in the Indenture. The Company shall mail to all Holders of record of the Securities a notice of the occurrence of
a Fundamental Change and of the repurchase right arising as a result thereof at any time following the Company entering into a definitive agreement that, if consummated, would give rise to a Fundamental Change, but in any event not later than the
fifth (5th) calendar day after the occurrence of a Fundamental Change. 
 Subject to and upon compliance with the provisions of the
Indenture, the Holder may surrender for conversion all or any portion of this Security that is in an integral multiple of $1,000. Upon conversion, the Holder shall be entitled to receive the consideration specified in the Indenture. No fractional
share of Common Stock shall be issued upon conversion of a Security. Instead, the Company shall pay cash in lieu of such fractional share of Common Stock as provided in the Indenture. The initial Conversion Rate shall be 63.4417 shares of Common
Stock per $1,000 principal amount of Securities, subject to adjustment in accordance with the provisions of the Indenture. If a Holder converts all or a part of this Security in connection with the occurrence of certain Fundamental Change
transactions, the Conversion Rate shall be increased in the manner and to the extent described in the Indenture. 
  

 Exh. A-7 








 Upon due presentment for registration of transfer of this Security at the office or agency of the Company
in the Borough of Manhattan, City of New York, a new Security or Securities 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, assessments or other governmental charge imposed in connection with any registration of transfer or exchange of Securities (except as otherwise set forth in the Base Indenture).
