as may, consistently herewith, be determined to be necessary or appropriate by the officers of the Company executing such Notes, as evidenced by their execution of the Notes. 
 The Company shall pay the principal of and interest on any Global Note in immediately available funds to the Depositary or its nominee, as the case may
be, as the registered Holder of such Global Note. The Company shall pay the principal of any Physical Notes at the office or agency designated by the Company for that purpose. The Company has initially designated the Trustee as its Paying Agent and
Security Registrar in respect of the Notes and its agency in New York, New York as a place where Notes may be presented for payment or for registration of transfer. The Company may, however, change the Paying Agent or Security Registrar for the
Notes without prior notice to the Holders thereof, and the Company may act as Paying Agent or Security Registrar for the Notes. 

  

 9 








 
Interest on any Physical Notes will be payable (i) to Holders of Physical Notes having an aggregate principal amount of Notes of $5,000,000 or less, by
check mailed to the Holders of such Notes at their address in the Security Register and (ii) to Holders having an aggregate principal amount of Physical Notes in excess of $5,000,000, either by check mailed to each Holder at its address in the
Security Register or, upon application by a Holder to the Security Registrar not later than the relevant Regular Record Date, by wire transfer in immediately available funds to that Holder’s account within the United States, which application
shall remain in effect until that Holder notifies, in writing, the Registrar to the contrary. 
 SECTION 2.02. Book-Entry Provisions for
Global Notes. (a) The Notes initially shall be issued in the form of one or more Global Notes without interest coupons (i) registered in the name of Cede & Co., as nominee of the Depositary and (ii) delivered to the
Trustee as custodian for the Depositary. 
 Members of, or participants in, the Depositary (“Agent Members”) shall have no
rights under this Supplemental Indenture or the Base Indenture with respect to any Global Note held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Note, and Cede & Co., or such other Person
designated by the Depositary as its nominee, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein
shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members,
the operation of customary practices governing the exercise of the rights of any Holder. 
 (b) Transfers of Global Notes shall be limited to
transfers in whole, but not in part, to the Depositary, its successors or their respective nominees. Notwithstanding anything to the contrary in Section 305 of the Base Indenture, interests of beneficial owners in a Global Note may be
transferred or exchanged, in whole or in part, for Physical Notes, only: (i) pursuant to clause (2) of the seventh paragraph of Section 305 of the Base Indenture regarding the Depositary being unwilling, unable or no longer permitted
under applicable law to continue in its capacity as Depositary for the Notes, including as a result of ceasing to be registered as a clearing agency under the Exchange Act, in each case if a successor Depositary is not appointed within 60 days or
(ii) if an Event of Default with respect to the Notes has occurred and is continuing, in the case of both clauses (i) and (ii) in accordance with the rules and procedures of the Depositary. Other than as set forth in this
Section 2.02(b), the Notes shall remain in global form as Global Notes. 
 (c) In connection with any transfer or exchange of a portion
of the beneficial interest in the Global Note to beneficial owners pursuant to Section 305 of the Base Indenture, the Security Registrar shall (if one or more Physical Notes are to be issued) reflect on its books and records the date and a
decrease in the principal amount of the Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or
more Physical Notes of like tenor and amount in accordance with Section 305 of the Base Indenture. 
 (d) In connection with the
transfer of the entire Global Note to beneficial owners pursuant to Section 305 of the Base Indenture, the Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee 

  

 10 








 
shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in the Global Note, an equal
aggregate principal amount of Physical Notes of authorized denominations and the same tenor. 
 (e) The Holder of Global Notes may grant
proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under this Supplemental Indenture, Base Indenture or the Notes.

 SECTION 2.03. CUSIP Numbers. In issuing the Notes, the Company may use “CUSIP” numbers (if then generally in use),
and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders of the Notes; provided that any such notice may state that no representation is made as to the correctness of such numbers as
printed on the Notes 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 of any change in the “CUSIP” numbers of the Notes. 
 SECTION 2.04. Reporting Requirement. The Company
shall deliver to the Trustee within 15 days after the same is filed with the Commission, copies of the quarterly and annual reports and of the information, documents and other reports, if any, that the Company is required to file with the Commission
pursuant to Section 13 or 15(d) of the Exchange Act, and the Company shall otherwise comply with the requirements of Trust Indenture Act Section 314(a). Any quarterly or annual reports or other information, documents or other reports that
the Company files with the Commission pursuant to Section 13 or 15(d) of the Exchange Act shall be deemed to be filed with the Trustee and transmitted to the Holders at the time such quarterly or annual reports or other information, documents
or other reports are publicly filed with the Commission on the Commission’s EDGAR and/or IDEA filing system (or successor system). The Trustee does not have the duty to review such information, documents or reports, is not considered to have
notice of the content of such information, documents or reports and does not have a duty to verify the accuracy of such information, documents or reports. 
 ARTICLE 3 
 FUNDAMENTAL CHANGES AND PURCHASES THEREUPON 
 SECTION 3.01. Purchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any time prior to July 1,
2015, then each Holder of Notes shall have the right, at such Holder’s option, to require the Company to purchase for cash any or all of such Holder’s Notes, or any portion of the principal amount thereof, that is equal to $1,000 or a
multiple of $1,000, on a date specified by the Company that is no earlier than the 20th Business Day following the date of, and no later than the 35th calendar day following the date of, delivery of the Fundamental Change Company Notice (as defined
below) (the “Fundamental Change Purchase Date”), at a purchase price equal to 100% of the principal amount thereof, together with accrued and unpaid interest thereon to, but excluding, the Fundamental Change Purchase Date (the
“Fundamental Change Purchase Price”); provided, however, that if a Fundamental Change Purchase Date is after a Regular Record Date and on or prior to the Interest Payment Date to 

  

 11 








 
which such Regular Record Date relates, the interest payable in respect of such Interest Payment Date shall be payable to the Holders of record as of the
corresponding Regular Record Date and the Fundamental Change Purchase Price shall be equal to 100% of the principal amount of the Notes to be purchased pursuant to this Article 3. The requirement for the Company to purchase any Notes on the
Fundamental Change Purchase Date will be subject to extension to comply with applicable law. 
 Purchases of Notes under this
Section 3.01 shall be made, at the option of the Holder thereof, upon: 
 (i) delivery to the Paying Agent by a Holder of
a duly completed notice (the “Fundamental Change Purchase Notice”) in the form set forth on the reverse of the Note as Exhibit C thereto, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for
tendering interests in Global Notes, if the Notes are not Physical Notes, in each case prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date ; and 
 (ii) delivery of the Notes, in the case of Physical Notes, to the Paying Agent appointed by the Company (together with all necessary
endorsements for transfer), or book-entry transfer of the Notes, in compliance with the procedures of the Depositary, such delivery or transfer being a condition to receipt by the Holder of the Fundamental Change Purchase Price therefor. 

The Fundamental Change Purchase Notice in respect of any Notes to be purchased shall state: 
 (i) if such Notes are Physical Notes, the certificate numbers of such Notes; 
 (ii) the portion of the principal amount of such Notes, which must be $1,000 or a multiple thereof; and 
 (iii) that such Notes are to be purchased by the Company pursuant to the applicable provisions of the Notes and this Supplemental
Indenture; 
 provided, however, that if such Notes are in global form, the Fundamental Change Purchase Notice must also comply with
appropriate procedures of the Depositary. 
 Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the
Fundamental Change Purchase Notice contemplated by this Section 3.01 shall have the right to withdraw, in whole or in part, such Fundamental Change Purchase Notice at any time prior to the close of business on the Business Day immediately
preceding the Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.03 below. 
 The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notice or written notice of withdrawal thereof. 
  

 12 








 (b) Fundamental Change Company Notice. On or before the 20th calendar day after the occurrence of
a Fundamental Change, the Company shall provide to all Holders of record of the Notes, the Trustee and the Paying Agent (in the case of any Paying Agent other than the Trustee) a notice (the “Fundamental Change Company Notice”) of
the occurrence of such Fundamental Change and of the purchase right at the option of the Holders arising as a result thereof. Such notice shall be sent by first class mail or, in the case of any Global Notes, in accordance with the procedures of the
Depositary for providing notices. Simultaneously with providing such Fundamental Change Company Notice, the Company shall publish a notice containing the information included therein in a newspaper of general circulation in New York, New York or
shall publish such information on the Company’s website or through such other public medium as the Company may use at such time. 
 Each
Fundamental Change Company Notice shall specify: 
 (i) the events causing a Fundamental Change; 
 (ii) the date of the Fundamental Change; 
 (iii) the last date on which a Holder of Notes may exercise the repurchase right pursuant to this Article 3; 
 (iv) the Fundamental Change Purchase Price; 
 (v) the Fundamental Change Purchase Date;

 (vi) the name and address of the Paying Agent and the Conversion Agent, if applicable; 
 (vii) if applicable, the applicable Conversion Rate and any adjustments to the applicable Conversion Rate; 
 (viii) if applicable, that the Notes with respect to which a Fundamental Change Purchase Notice has been delivered by a Holder may be
converted only if the Holder withdraws the Fundamental Change Purchase Notice in accordance with the Indenture; and 
 (ix)
the procedures that Holders must follow to require the Company to purchase their Notes. 
 No failure of the Company to give the foregoing
notices and no defect therein shall limit the purchase rights of the Holders of Notes or affect the validity of the proceedings for the purchase of the Notes pursuant to this Section 3.01. 
 (c) No Payment During Events of Default. There shall be no purchase of any Notes pursuant to this Section 3.01 if there has occurred
and is continuing an Event of Default with respect to the Notes (other than an Event of Default that is cured by the payment of the Fundamental Change Purchase Price of the Notes). The Paying Agent will promptly return to the respective Holders
thereof any Physical Notes held by it during the continuance of an Event of Default (other than an Event of Default that is cured by the 

  

 13 








 
payment of the Fundamental Change Purchase Price with respect to 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 Purchase Notice with respect thereto shall be deemed to have been withdrawn. 
 SECTION 3.02. Effect of Fundamental Change Purchase Notice. Upon receipt by the Paying Agent of the Fundamental Change Purchase Notice
specified in Section 3.01 hereof, the Holder of the Note in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn in accordance with Section 3.03 hereof)
thereafter be entitled to receive solely the Fundamental Change Purchase Price in cash with respect to such Note. Such Fundamental Change Purchase Price shall be paid to such Holder, subject to receipt of funds by the Paying Agent, on the later of
(x) the Fundamental Change Purchase Date with respect to such Note (provided the conditions in Section 3.01 hereof have been satisfied) and (y) the time of delivery or book-entry transfer of such Note to the Paying Agent by the
Holder thereof in the manner required by Section 3.01 hereof. 
 SECTION 3.03. Withdrawal of Fundamental Change Purchase
Notice. A Fundamental Change Purchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with the Fundamental Change Company Notice at any time prior to the close
of business on the Business Day immediately preceding the Fundamental Change Purchase Date, specifying: 
 (i) the principal
amount of the Notes with respect to which such notice of withdrawal is being submitted; 
 (ii) if Physical Notes have been
issued, the certificate numbers of the withdrawn Notes; and 
 (iii) the principal amount, if any, of such Notes that remains
subject to the original Fundamental Change Purchase Notice, which portion must be in principal amounts of $1,000 or a multiple of $1,000; 
 provided,
however, that if Physical Notes have not been issued, the notice must comply with appropriate procedures of the Depositary. 
 The
Paying Agent will promptly return to the respective Holders thereof any Physical Notes with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with the provisions of this Section 3.03. 
 SECTION 3.04. Deposit of Fundamental Change Purchase Price. Prior to 11:00 a.m. (local time in The City of New York) on the Fundamental Change
Purchase Date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided herein) an amount of money (in
immediately available funds if deposited on such Business Day) sufficient to pay the Fundamental Change Purchase Price of all the Notes or portions thereof that are to be purchased as of the Fundamental Change Purchase Date. If the Paying Agent
holds cash 

  

 14 








 
sufficient to pay the Fundamental Change Purchase Price of the Notes for which a Fundamental Change Purchase Notice has been tendered and not withdrawn in
accordance with this Supplemental Indenture on the Fundamental Change Purchase Date, then as of such Fundamental Change Purchase Date, (a) such Notes will cease to be outstanding and interest will cease to accrue thereon (whether or not
book-entry transfer of such Notes is made or such Notes have been delivered to the Paying Agent) and (b) all other rights of the Holders in respect thereof will terminate (other than the right to receive the Fundamental Change Purchase Price
and previously accrued and unpaid interest upon delivery or book-entry transfer of such Notes). 
 SECTION 3.05. Notes Purchased in
Whole or in Part. Any Note that is to be purchased, whether in whole or in part, shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires in the case of Physical Notes, due endorsement by, or a
written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and
deliver to the Holder of such Note, without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note
so surrendered that is not purchased. 
 SECTION 3.06. Covenant to Comply With Applicable Laws Upon Purchase of Notes. In
connection with any offer to purchase Notes under Section 3.01 hereof, the Company shall, in each case if required, (i) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable,
(ii) file a Schedule TO or any other required schedule under the Exchange Act and (iii) otherwise comply with all federal and state securities laws so as to permit the rights and obligations under Section 3.01 to be exercised in the
time and in the manner specified in Section 3.01. 
 SECTION 3.07. Repayment to the Company. To the extent that the aggregate
amount of cash deposited by the Company pursuant to Section 3.04 exceeds the aggregate Fundamental Change Purchase Price of the Notes or portions thereof that the Company is obligated to purchase as of the Fundamental Change Purchase Date,
then, following the Fundamental Change Purchase Date, the Paying Agent shall promptly return any such excess to the Company. 
 ARTICLE 4

 CONVERSION 
 SECTION
4.01. Right to Convert. (a) Subject to the procedures for conversion set forth in this Article 4 and at any time prior to the close of business on the second Scheduled Trading Day immediately preceding July 1, 2015, a Holder may
convert its Notes at their full principal amount, or any portion of such principal amount that is equal to $1,000 or an integral multiple of $1,000. No payment or adjustment shall be made for dividends on, or other distributions with respect to, any
Common Stock, except as expressly provided in this Article 4. 
 (b) Notes may not be converted after the close of business on the second
Scheduled Trading Day immediately preceding July 1, 2015. 
  

 15 








 SECTION 4.02. Conversion Procedures. (a) Each Note 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, and pay the funds, if any, required by Section 4.02(e) and any taxes or duties if required pursuant to Section 4.07, 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 Physical 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 (the “Conversion Notice”) or a
facsimile of the Conversion Notice; 
 (ii) deliver the Conversion Notice, which is irrevocable, and the Note to the
Conversion Agent; 
 (iii) if required, furnish appropriate endorsements and transfer documents as may be required by the
Conversion Agent, 
 (iv) make any payment required under Section 4.02(e); and 
 (v) if required, pay all transfer or similar taxes as set forth in Section 4.07. 
 The date on which the Holder satisfies all of the applicable requirements set forth above is the “Conversion Date.” At the Conversion
Date the rights of the Holders of such converted Notes as Holders shall cease, and the Person or Persons entitled to receive the shares of Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of
such Common Stock as and after such time. The Company shall issue and shall deliver at such office or agency a certificate or certificates for the number of full shares of Common Stock issuable upon conversion, together with payment in cash in lieu
of any fractional shares, as provided in Section 4.02(c), by the third Business Day immediately following the Conversion Date (the “Settlement Date”). A Holder may convert a portion of its Notes only if the principal amount of
such portion is $1,000 or an integral multiple thereof. 
 In the case of any Note that is converted in part only, upon such conversion the
Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Company, a new Note or Notes of authorized denominations in aggregate principal amount equal to the unconverted portion of the
principal amount of such Note. 
 If a Holder has already delivered a Fundamental Change Purchase Notice in connection with a Fundamental
Change, with respect to a Note, the Holder may not surrender that Note for conversion until the Holder has validly withdrawn the Fundamental Change Purchase Notice in accordance with this Supplemental Indenture. 
  

 16 








 If more than one Note shall be surrendered for conversion at one time by the same Holder, the number of
full shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof) so surrendered. 
 (c) The Company shall not issue fractional shares of Common Stock upon conversion of Notes. Instead the Company shall deliver cash, rounded to the
nearest whole cent, for such fractional shares based on the Last Reported Sale Price of the Common Stock on the applicable Conversion Date. 
 (d) Subject to Section 4.02(e) below, upon conversion, Holders shall not receive any separate cash payment for accrued and unpaid interest or Additional Interest, if any, unless such conversion occurs between a Regular Record Date and
the Interest Payment Date to which it relates. 
 (e) Upon the conversion of any Notes, the Holder will not be entitled to receive any
separate cash payment for accrued and unpaid interest or Additional Interest, if any, except to the extent specified below. 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 and Additional Interest, if any, to, but not including, the
Conversion Date. As a result, accrued and unpaid interest and Additional Interest, if any, to, but not including, the Conversion Date will be deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the foregoing,
if Notes are converted after the close of business on a Regular Record Date for the payment of interest, Holders of such Notes at the close of business on such Regular Record Date will receive the interest and Additional Interest, if any, payable on
such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the opening of business on the immediately following
Interest Payment Date must be accompanied by funds equal to the amount of interest and Additional Interest, if any, payable on the Notes so converted; provided that no such payment need be made (i) for conversions following the Regular
Record Date immediately preceding July 1, 2015, (ii) if the Company has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, or (iii) to the
extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note. 
 SECTION 4.03.
Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company will not make any adjustment to the Conversion Rate if Holders of Notes
participate, as a result of holding the Notes, in any of the transactions described in this Section 4.03 without having to convert their Notes, as if such Holders held a number of shares of Common Stock equal to the Conversion Rate in effect
for such Notes immediately prior to the Ex-Dividend Date for such event. 
 (a) If the Company, at any time or from time to time while any of
the Notes are outstanding, issues shares of its Common Stock as a dividend or distribution on shares of its Common Stock, or if the Company effects a share split or share combination, then the Conversion Rate will be adjusted based on the following
formula: 
 

 
  

 17 








 where 
  

					
	CR0	 	=	  	The Conversion Rate in effect immediately prior to the opening of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the opening of business on the
effective date of such share split or share combination, as applicable;
			
	CR1	 	=	  	The Conversion Rate in effect immediately after the opening of business on such Ex-Dividend Date or such effective date;
			
	OS0	 	=	  	The number of shares of Common Stock outstanding immediately prior to the opening of business on such Ex-Dividend Date or such effective date; and
			
	OS1	 	=	  	The number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

 Such adjustment shall become effective immediately after the opening of business on the Ex-Dividend Date for such
dividend or distribution or the effective date for such share split or share combination. If any dividend or distribution of the type described in this Section 4.03(a) is declared but not so paid or made, the Conversion Rate shall again be
immediately readjusted, effective as of the date that the Board of Directors of the Company determined not to pay such dividend or distribution to the Conversion Rate which would then be in effect if such dividend or distribution had not been
declared. 
 (b) If the Company, at any time or from time to time while any of the Notes are outstanding, issues to all or substantially all
holders of the Common Stock any rights or warrants entitling them for a period of not more than 60 calendar days after the announcement date of such issuance to subscribe for or purchase shares of the Common Stock at a price per share less than the
average of the Last Reported Sale Prices of Common Stock for the 10 consecutive Trading-Day period ending on the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be adjusted based on the
following formula: 
 

 
 where 
  

					
	CR0	 	=	  	The Conversion Rate in effect immediately prior to the opening of business on the Ex-Dividend Date for such issuance;

  

 18 









					
	CR1	 	=	  	The Conversion Rate in effect immediately after the opening of business on such Ex-Dividend Date;
			
	OS0	 	=	  	The number of shares of Common Stock outstanding immediately prior to the opening of business on such Ex-Dividend Date;
			
	X	 	=	  	The total number of shares of Common Stock issuable pursuant to such rights or warrants; and
			
	Y	 	=	  	The number of shares of Common Stock equal to the aggregate price payable to exercise such rights or warrants divided by the average of the Last Reported Sale Prices of the Common Stock
over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of the issuance of such rights or warrants.

 To the extent such rights or warrants are not exercised prior to their expiration or termination, the Conversion
Rate shall be readjusted to the Conversion Rate which would be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock actually delivered. In
the event that such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if the date fixed for the determination of shareholders entitled to receive such rights or
warrants had not been fixed. For the purposes of this Section 4.03(b), in determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than the average of the Last Reported Sale
Prices of Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of such issuance, and in determining the aggregate exercise price payable for 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 the exercise thereof, with the value of such consideration, if other than cash, as shall be determined in good faith by
the Board of Directors. 
 (c) If the Company, at any time or from time to time while the Notes are outstanding, distributes shares of any
class of capital stock of the Company, evidences of its indebtedness, other assets or property of the Company or rights or warrants to acquire the Company’s capital stock or other securities to all or substantially all holders of its Common
Stock, excluding: 
 (i) dividends or distributions and rights or warrants as to which an adjustment was effected pursuant to
Section 4.03(a) or Section 4.03(b); 
 (ii) dividends or distributions paid exclusively in cash; and 
 (iii) Spin-Offs to which the provisions set forth below in this Section 4.03(c) shall apply; 
 then the Conversion Rate shall be increased based on the following formula: 
 

 
  

 19 








 where 
  

					
	CR0	 	=	  	the Conversion Rate in effect immediately prior to the opening of business on the Ex-Dividend Date for such distribution;
			
	CR1	 	=	  	the Conversion Rate in effect immediately after the opening of business on such Ex-Dividend Date;
			
	SP0	 	=	  	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such
distribution; and
			
	FMV	 	=	  	the fair market value (as determined by the Board of Directors) of the shares of capital stock, evidences of indebtedness, assets, property, rights or warrants distributed with respect to each
outstanding share of the Common Stock on the Ex-Dividend Date for such distribution.

 Such adjustment shall become effective immediately after
the opening of business on the Ex-Dividend Date for such distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this Section 4.03(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 10 consecutive Trading Day period used in computing the average of the Last Reported Sale Prices of the Common Stock. Notwithstanding the
foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing
adjustment, each Holder of Notes shall receive, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of securities and assets such Holder would have received as if such Holder owned a number of shares of
Common Stock equal to the Conversion Rate in effect immediately prior to the Record Date for the distribution of the securities or assets. 
 With respect to
an adjustment pursuant to this Section 4.03(c), where there has been a payment of a dividend or other distribution on the Common Stock of shares of capital stock of any class or series, or similar equity interest, of or relating to a Subsidiary
or other business unit and such dividend or distribution is listed for trading on a securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 
 

 
  

 20 








 where 
  

					
	CR0	 	=	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period (as defined below);
			
	CR1	 	=	  	the Conversion Rate in effect immediately after the end of the Valuation Period;
			
	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 (determined for
purposes of the definition of Last Reported Sale Price as if such capital stock or similar equity interest were the Common Stock), over the first ten consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the
“Valuation Period”); and
			
	MP0	 	=	  	the average of the Last Reported Sale Prices of Common Stock over the Valuation Period.

 The adjustment to the Conversion Rate under the preceding paragraph will occur on the last day of the Valuation
Period; provided that in respect of any conversion during the Valuation Period, references above to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off
and the Conversion Date in determining the applicable Conversion Rate. 
 For the purposes of this Section 4.03(c) (and subject in all
respects to Section 4.10), rights or warrants distributed by the Company to all holders of its Common Stock entitling them to subscribe for or purchase shares of the Company’s capital stock (either initially or under certain
circumstances), which rights or warrants, until the occurrence of a specified event or events (a “Trigger Event”): (1) are deemed to be transferred with such shares of Common Stock; (2) are not exercisable; and
(3) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.03(c), (and no adjustment to the Conversion Rate under this Section 4.03(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 4.03(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 Ex-Dividend Date of such deemed distribution (in
which case the original rights or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders). 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 4.03(c) was made,
(1) in the case of any such rights or warrants which shall all have been redeemed or purchased without exercise by any Holders thereof, upon such final redemption or repurchase (x) the Conversion Rate shall be readjusted as if such rights
or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case 

  

 21 








 
may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by holders of Common Stock with respect to such
rights or warrants (assuming each such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights or warrants which shall have expired or
been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued. 
 For the purposes of this Section 4.03(c) and subsections (a) and (b) of this Section 4.03, any dividend or distribution to which this Section 4.03(c) applies which also includes one or both
of: 
  

	 	(A)	a dividend or distribution of shares of Common Stock to which Section 4.03(a) applies (the “Clause A Distribution”); 

  

	 	(B)	a dividend or distribution of rights or warrants to which Section 4.03(b) applies (the “Clause B Distribution”), 

 then (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to
which this Section 4.03(c) applies (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 4.03(c) with respect thereto shall then be made, and (2) the Clause A Distribution and
Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 4.03(a) and Section 4.03(b) with respect thereto shall then be made, except that, if determined by
the Company, (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A
Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the opening of business on such Ex-Dividend Date or such effective date” within the meaning of Section 4.03(a) or “outstanding
immediately prior to the opening of business on such Ex-Dividend Date” within the meaning of Section 4.03(b). 
 If any dividend or distribution
(including a Spin-Off described in this Section 4.03(c)) is declared but not paid or made, the new Conversion Rate shall be readjusted, effective as of the date that the Board of Directors of the Company determined not to pay such dividend or
distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (d) (i) If any
cash dividend or distribution is made to all or substantially all holders of Common Stock, the Conversion Rate shall be increased based on the following formula: 
 

 
  

 22 








 where 
  

					
	CR0	 	=	  	The Conversion Rate in effect immediately prior to the opening of business on the Ex-Dividend Date for such dividend or distribution;
			
	CR1	 	=	  	The Conversion Rate in effect immediately after the opening of business on the Ex-Dividend Date for such dividend or distribution;
			
	SP0	 	=	  	The Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
			
	C	 	=	  	The amount in cash per share the Company distributes to holders of the Common Stock.

 In the case of an adjustment pursuant to this Section 4.03(d), such adjustment shall become effective
immediately after the opening of business on the Ex-Dividend Date for the relevant dividend or distribution. If the portion of the cash so distributed applicable to one share of the Common Stock is equal to or greater than the Last Reported Sale
Price of a share of Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution, in lieu of the adjustment set forth above, adequate provision shall be made so that each Holder of Notes shall have the
right to receive on the date on which such cash dividend or distribution is distributed to holders of Common Stock, for each $1,000 principal amount of Notes, the amount of cash such Holder would have received had such Holder owned a number of
shares of Common Stock equal to the Conversion Rate in effect immediately prior to the Ex-Dividend Date for such distribution. 
 If any dividend or
distribution of the type described in this Section 4.03(d) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date that the Board of Directors of the Company determined not to pay such
dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (e)
If 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 per share of Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following
formula: 
 

 
 where 
  

					
	CR0	  	=	  	The Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or
exchange offer expires;

  

 23 









					
	CR1	  	=	  	The Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading 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;
			
	OS1	  	=	  	The number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to, for the avoidance of doubt, the purchase of all shares
accepted for purchase or exchange in such tender or exchange offer); and
			
	SP1	  	=	  	The average of the Last Reported Sale Prices of Common Stock over the 10 consecutive Trading Day period commencing on the Trading Day next succeeding the date such tender or exchange offer
expires.

 The adjustment to the Conversion Rate under this Section 4.03(e) shall occur as of the close of business on
the tenth Trading Day from, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any conversion within 10 Trading Days immediately following, and including, the expiration
date of any tender or exchange offer, references with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the expiration date of such tender or exchange offer and the Conversion Date in
determining the applicable Conversion Rate. 
 (f) The Company from time to time may increase the Conversion Rate by any amount for any
period of time of at least 20 Business Days, so long as the increase is irrevocable during the period and the Board of Directors shall have made a determination that such increase would be in the best interests of the Company, which determination
shall be conclusive. Whenever the Conversion Rate is increased pursuant to this Section 4.03(f), the Company shall mail to Holders of record of the Notes a notice of the increase at least one day prior to the date the increased Conversion Rate
takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 
 (g) The Company
may (but shall not be required to) increase the Conversion Rate, in addition to any adjustments pursuant to Section 4.03(a), 4.03(b), 4.03(c), 4.03(d), 4.03(e) or 4.03(f), if the Board of Directors considers such increase 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 similar event. 
 (h) All calculations under this Article 4 shall be made by the Company and shall be made to the nearest cent (including, in the case of any adjustment to
the Conversion Rate, the resulting adjustment to the Conversion Price) or to the nearest one ten-thousandth of a share. No adjustment shall be required to be made for the Company’s issuance of Common Stock or any securities convertible into or
exchangeable for shares of Common Stock or rights to purchase shares of Common Stock or such convertible or exchangeable securities, other than as provided in this Section 4.03 and in Section 4.10 hereof. 
  

 24 








 (i) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the
Trustee and any Conversion Agent an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee
shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in
effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such
notice of such adjustment of the Conversion Rate to each Holder of the Notes. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 
 (j) For purposes of this Section 4.03, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of
the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of
shares of Common Stock. 
 (k) Notwithstanding the foregoing, if the application of the foregoing formulas set forth in this
Section 4.03 would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate shall be made (other than as a result of a share combination). 
 (l) Notwithstanding anything to the contrary in this Article 4, no adjustment to the Conversion Rate shall be made upon issuance of any shares of our Common Stock (including, shares of Common Stock issued in the
Concurrent Offering) or: 
 (i) upon the issuance of any shares of Common Stock pursuant to any present or future plan
providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; 
 (ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future
employee, director or consultant benefit plan or program of or assumed by the Company or any 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 clause (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 on the Notes, if any. 
 (m) The Company shall 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 make such carried forward adjustment, regardless of whether the aggregate adjustment is less than 1% upon any Conversion Date of Notes. 
  

 25 








 SECTION 4.04. Certain Other Adjustments. Whenever a provision of this Supplemental Indenture
requires the calculation of Last Reported Sale Prices over a span of multiple days, the Board of Directors will make appropriate adjustments to such Last Reported Sale Prices, the Conversion Rate, or the amount due upon conversion to account for any
adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date of the event occurs, at any time during the period from which such Last Reported Sale Prices are to be
calculated. 
 SECTION 4.05. Adjustments Upon Certain Fundamental Changes. (a) If a Make-Whole Fundamental Change occurs and a
Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under certain circumstances, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of
Common Stock (the “Additional Shares”) as described below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the notice of conversion of the Notes is
received by the Conversion Agent from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change Purchase Date. 
 (b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall deliver shares of Common Stock,
including the Additional Shares, as provided under Section 4.02; provided, however, that if, at the effective time of a Make-Whole Fundamental Change, the Reference Property is comprised entirely of cash, then, for any conversion of Notes
following the effective date of such Make-Whole Fundamental Change, the amounts deliverable by the Company shall be calculated based solely on the “Stock Price” (as defined below) for the Make-Whole Fundamental Change and shall be deemed
to be an amount equal to the Conversion Rate (including any adjustment for Additional Shares) multiplied by such Stock Price. In such event, the amounts deliverable by the Company shall be determined and paid to holders in cash on the third Business
Day following the Conversion Date. 
 (c) The number of Additional Shares, if any, by which the Conversion Rate will be increased will be
determined by reference to the table attached as Schedule A hereto, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”)
paid (or deemed paid) per share of the Common Stock in the Fundamental Change. If the holders of the Common Stock receive only cash in a Make-Whole Fundamental Change described in clause (2) of the definition of Fundamental Change, the Stock
Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the ten Trading-Day period ending on, and including, the Trading Day immediately preceding the
Effective Date of the Make-Whole Fundamental Change. 
  

 26 








 The exact Stock Prices and Effective Dates may not be set forth in the table in Schedule A hereto,
in which case the following shall apply: 
 (i) If the Stock Price is between two Stock Prices in the table or the Effective
Date is between two Effective Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later
Effective Dates, as applicable, based on a 365-day year. 
 (ii) If the Stock Price is greater than $90.00 per share (subject
to adjustment in the same manner as the Stock Prices set forth in the column headings of the table in Schedule A pursuant to subsection (d) below), no Additional Shares shall be added to the Conversion Rate. 
 (iii) If the Stock Price is less than $22.00 per share (subject to adjustments in the same manner as the Stock Prices set forth in the
column headings of the table in Schedule A pursuant to subsection (d) below), no Additional Shares shall be added to the Conversion Rate. 
 Notwithstanding the foregoing, in no event shall the Conversion Rate exceed 45.4545 shares of Common Stock per $1,000 principal amount of Notes, subject to adjustments in the same manner as the Conversion Rate as set forth in
Section 4.03. 
 (d) The Stock Prices set forth in the column headings of the table in Schedule A hereto shall be adjusted as of any
date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate
immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in such table shall be adjusted in the same manner as the
Conversion Rate as set forth in Section 4.03. 
 (e) The Company shall notify the Holders of Notes of the Effective Date of any
Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date. 
 SECTION 4.06. Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale. 
 (a) If any of the following
events occur: 
 (i) any recapitalization or reclassification of, or change in, the Common Stock (other than changes resulting
from a subdivision or combination); 
 (ii) a consolidation, merger or combination involving the Company; or 
 (iii) a sale, lease or other transfer to a third party of all or substantially all of the assets of the Company; or 
  

 27 








 (iv) any statutory share exchange; 
 in each case, as a result of which the Common Stock would be converted into, or exchanged for, or would be reclassified or changed into, stock, other securities, other
property or assets (including cash or any combination thereof) (any such event, a “Merger Event”), then at the effective time 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, the right to convert
a Note will be changed into a right to convert such Note as set forth in this Indenture into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number
of shares of Common Stock equal to the Conversation Rate prior to such Merger Event would have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference Property” meaning the type and
amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon such Merger Event; provided, however, that at and after the effective time of the Merger Event the conversion obligation shall be calculated and
settled in accordance with Section 4.03 such that the number of shares of Common Stock otherwise deliverable upon conversion of the Notes under Section 4.03 will be instead deliverable in the amount and type of Reference Property that a
holder of that number of shares of Common Stock would have been entitled to receive in such Merger Event. 
 If, as a result of the Merger
Event, each share of Common Stock is converted into the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then (x) the Reference Property into which the Notes will be
convertible will be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election, and (y) the unit of Reference Property for purposes of the
foregoing sentence shall refer to the consideration referred to in clause (x) attributable to one share of Common Stock. 
 The Company
shall not become a party to any such Merger Event unless its terms are consistent with this Section 4.06. 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 4 in the judgment of the Board of Directors or the board of directors of the successor Person. If, in the case of any such recapitalization, reclassification, change, consolidation, merger, combination, sale, lease,
other transfer or statutory share exchange, the Reference Property receivable thereupon by a holder of Common Stock includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than
the successor or purchasing Person, as the case may be, in such reorganization, reclassification, change, consolidation, merger, combination, sale, lease, other transfer or statutory share exchange, then such supplemental indenture shall also be
executed by such other Person. 
 (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 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 4.06 shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and conveyances. If this Section 4.06 applies to any Merger Event,
Section 4.03 shall not apply. 
  

 28 








 SECTION 4.07. Taxes on Shares Issued. The Company will pay any documentary, stamp or similar issue
or transfer tax due on the issue or delivery of shares of Common Stock on conversion of Notes pursuant hereto; provided, however, that if such documentary, stamp or similar issue or transfer tax is due because the Holder of such Notes has requested
that shares of Common Stock be issued in a name other than that of the Holder of the Notes converted, then such taxes will be paid by the Holder, and the Company shall not be required to issue or deliver any stock certificate evidencing such shares
unless and until the Holder 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 4.08. Reservation of Shares; Shares to be Fully Paid; Compliance With Governmental Requirements; Listing of Common Stock. The Company
shall reserve, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to satisfy conversion of the Notes from time to time as such Notes are presented for conversion (assuming that, at the time of the
computation of such number of shares or securities, all such Notes would be converted by a single Holder). 
 The Company covenants that all
shares of Common Stock that may be issued upon conversion of Notes shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free from any
tax, lien or charge (other than those created by the Holder). 
 The Company shall list or cause to have quoted any shares of Common Stock to
be issued upon conversion of Notes on each national securities exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted. 
 SECTION 4.09. Responsibility of Trustee. The Trustee and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Notes to determine or calculate the Conversion Rate or
any of the components thereof, to determine whether any facts exist which may require any adjustment of the Conversion Rate, or to confirm the accuracy of any such adjustment when made or the appropriateness of 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 other
securities or property that may at any time be issued or delivered upon the conversion of any Notes; and the Trustee and the 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 Notes for the purpose of conversion or to comply with any of
the duties, responsibilities or covenants of the Company contained in this Article 4. The rights, privileges, protections, immunities and benefits given to the Trustee, including without limitation its right to be compensated, reimbursed, and
indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including its capacity as Conversion Agent. 
  

 29 








 SECTION 4.10. 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 4.03; 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 that would require an adjustment in the Conversion Rate pursuant to Section 4.03 or Section 4.11 hereof; or 
 (c) of any reclassification or reorganization of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common
Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of
the sale, lease or transfer of all or substantially all of the assets of the Company and its consolidated Subsidiaries; or 
 (d) of the
voluntary or involuntary dissolution, liquidation or winding up of the Company or any of its Subsidiaries; 
 then, in each case (unless notice of such event
is otherwise required pursuant to another provision of this Supplemental Indenture), the Company shall cause to be filed with the Trustee and the Conversion Agent and to be mailed to each Holder of Notes at such Holder’s address appearing on a
list of Holders of Notes, which the Company shall provide to the Trustee, as promptly as practicable but in any event at least 10 days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of such dividend (or any other distribution) or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights or
warrants are to be determined, or (y) the date on which such reclassification, reorganization, consolidation, merger, sale, lease, transfer, dissolution, liquidation or winding up is expected to become effective or occur, and the date as of
which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, reorganization, consolidation, merger, sale, 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 (or any other distribution), reclassification, reorganization, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up. 
 SECTION 4.11. Stockholder Rights Plan. Each share of Common Stock issued upon conversion of
Notes pursuant to this Article 4 shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided
by the terms of any stockholder rights plan adopted by the Company, as the same may be amended from time to time. Notwithstanding the foregoing, if prior to any conversion such rights have separated from the shares of Common Stock in accordance with
the provisions of the applicable stockholder rights agreement, the Conversion Rate shall be adjusted at the time of separation as if the Company had distributed to all holders of the Common Stock, shares of the Company’s capital stock,
evidences of indebtedness, assets, property, rights or warrants as described in Section 4.03 above, subject to readjustment in the event of the expiration, termination or redemption of such rights. 
  

 30 








 ARTICLE 5 
 REMEDIES 
 SECTION 5.01. Events of Default. For purposes of the Notes, Section 501 of
Article V of the Base Indenture is hereby replaced in its entirety by the following provision: “Event of Default” wherever used herein with respect to the Notes shall mean any one of the following events (whatever the reason for such Event
of Default and whether it shall be voluntary or involuntary or be effected by operation of law pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): 
 (a) default in the payment of interest, including any Additional Interest, on any Note when such interest or Additional Interest becomes due and payable

of such failure, requiring the Company to remedy the same, shall have been given to the Company by the Trustee, or the Company and a Responsible Officer of the Trustee by the Holders of at least twenty-five percent (25%) in aggregate principal
amount of the Notes at the time Outstanding. 
 (g) an event of default as defined in any mortgage, indenture or instrument under which there

indebtedness in principal amount in excess of $20,000,000 becoming or being declared due and payable prior to the date on which it would otherwise become due and payable, and such acceleration shall not be rescinded or annulled, or such indebtedness
shall not have been discharged, within a period of 60 days after there shall have been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the
Notes then Outstanding, a written notice specifying such Event of Default and requiring the Company to cause such acceleration to be rescinded or annulled or to cause such indebtedness to be discharged; 
  

 31 








 (h) a final judgment for the payment of $20,000,000 or more (excluding any amounts covered by insurance)

benefit of creditors, or the admission by the Company or a Principal Subsidiary in writing of its inability to pay its debts generally as they become due. 
 SECTION 5.02. Acceleration of Maturity; Rescission and Annulments. For purposes of the Notes, Section 502 of the Base Indenture is hereby amended as follows: 
 (a) The first paragraph of Section 502 of the Base Indenture is replaced by the following provision: If an Event of Default with respect to the Notes
occurs and is continuing (other than an Event of Default specified in Section 5.01(i) or (j) with respect to the Company), then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Notes then
Outstanding may declare the principal amount (and the interest accrued and unpaid, including any Additional Interest) of all of the Notes to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by
Holders), and upon any such declaration such amount shall become immediately due and payable. If an Event of Default specified in Section 501(i) or (j) with respect to the Company occurs and is continuing, then in every such case the
principal amount (and the interest accrued and unpaid, including any Additional Interest) of all of the Notes shall become and be immediately due and payable without any declaration or other action on the part of the Trustee or any Holder.

  

 32 








 (b) Subclause (2) of the second paragraph of Section 502 of the Base Indenture is replaced with
the following provision: all Events of Default with respect to the Notes, other than the non-payment of amounts of principal of (or premium, if any, on) the Notes, which have become due solely by such declaration of acceleration, have been cured or
waived as provided in Section 513 of the Base Indenture. 
 (c) The third paragraph of Section 502 of the Base Indenture shall be
replaced with the following provision: Notwithstanding any provisions of the Indenture to the contrary, if the Company so elects, the sole remedy for an Event of Default relating to any failure by the Company to file documents and reports with the
Trustee as required by Section 314(a)(1) of the Trust Indenture Act, Section 2.04 of this Supplemental Indenture, or Section 703 of the Base Indenture shall for the first 180 days following the occurrence of such Event of Default
consist exclusively of the right to receive additional interest on the Notes equal to 0.50% of the principal amount of the Notes (“Additional Interest”). In order to elect to pay Additional Interest as the sole remedy during the
first 180 days after the occurrence of an Event of Default described in the preceding sentence, the Company must (i) give notice to Holders of the Notes, the Trustee and the Paying Agent of such election on or before the close of business on
the fifth Business Day after the date on which such Event of Default occurs and (ii) pay such Additional Interest on or before the date on which such Event of Default first occurs. Upon the failure to timely give all Holders, the Trustee and
the Paying Agent such notice or to pay such Additional Interest, the Notes will be subject to immediate acceleration as provided herein. On the 120th day after such Event of Default occurs (if such Event of Default is not cured or waived prior to
such 120th day), the Notes shall be subject to acceleration as provided herein. This Section 5.02(c) shall not affect the rights of Holders of Notes in the event of the occurrence of any other Event of Default. Whenever in the Indenture there
is mentioned, in any context, the payment of interest on, or in respect of, any Note, such mention shall be deemed to include mention of the payment of Additional Interest provided for in this Section 5.02(c) to the extent that, in such
context, Additional Interest is, was or would be payable in respect thereof pursuant to the provisions of this Section 5.02(c), and express mention of the payment of Additional Interest (if applicable) in any provision shall not be construed as
excluding Additional Interest in those provisions where such express mention is not made. 
 SECTION 5.03. Company Compliance Certificates
and Notice of Defaults. In addition to any obligations of the Company under Section 704 of the Base Indenture, the Company shall deliver to the Trustee, (i) within 120 days after the end of each fiscal year, an
Officers’ Certificate indicating whether or not the signers thereof have knowledge of the occurrence of any Event of Default under the Indenture during such fiscal year, and (ii) within 5 days after the occurrence thereof, written notice
of any events that would constitute an Event of Default under the Indenture, the status of such events and the action that the Company is taking or proposes to take in respect thereof. 
 SECTION 5.04. Trustee May File Proofs of Claim. For purposes of the Notes, the first paragraph of Section 504 of the Base Indenture is hereby
replaced by the following provision: In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other 

  

 33 








 
obligor upon the Notes or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the
Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal, premium, if any, or interest) shall be
entitled and empowered, but not required, by intervention in such proceeding or otherwise, 
  

	 	(1)	to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the Notes and to file such other papers or documents as
may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial
proceeding, and 

  

	 	(2)	to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; 

 and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to
make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 606 of the Base Indenture. 
 ARTICLE 6

 SATISFACTION AND DISCHARGE 
 The satisfaction and discharge provisions set forth in this Article 6 shall, with respect to the Notes, supersede in their entirety Articles IV and XIV of the Base Indenture, and all references in the Base Indenture to Articles IV and XIV
thereof and satisfaction and discharge provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 6 and the satisfaction and discharge provisions set forth in this Article 6, respectively.

 SECTION 6.01. Satisfaction and Discharge of the Supplemental Indenture. When (i) the Company shall deliver to the Registrar
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
(ii) all the Notes not theretofore canceled or delivered to the Trustee for cancellation shall have become due and payable (whether at Stated Maturity for the payment of the principal amount thereof or on any Fundamental Change Purchase Date)
and the Company shall deposit with the Trustee, in trust, or deliver to the Holders, as applicable, cash funds and shares of Common Stock, as applicable, sufficient to pay all amounts due (and shares of Common Stock deliverable following conversion,
if applicable) on all of such Notes (other than any Notes that shall have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) not theretofore canceled or
delivered to the Trustee for cancellation, including principal and interest due, 

  

 34 








 
accompanied, except in the event the Notes are due and payable solely in cash at the Stated Maturity of the Notes or upon an earlier Fundamental Change
Purchase Date, by a verification report as to the sufficiency of the deposited amount from an independent certified accountant or other financial professional reasonably satisfactory to the Trustee (which may include any of the Underwriters), and if
the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this Supplemental Indenture shall cease to be of further effect (except as to (A) rights hereunder of Holders of the Notes to receive all
amounts owing upon the Notes and the other rights, duties and obligations of Holders of the Notes, as beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee and (B) the rights, obligations and immunities of the
Trustee hereunder), and the Trustee, on written demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel as required by Section 102 of the Base Indenture and at the cost and expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this Supplemental Indenture; the Company, however, hereby agrees to reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred by the Trustee,
including the fees and expenses of its counsel, and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this Supplemental Indenture or the Notes. 
 SECTION 6.02. Deposited Monies to be Held in Trust by Trustee. Subject to Section 6.04, all monies deposited with the Trustee pursuant to
Section 6.01 shall be held in trust for the sole benefit of the Holders of the Notes, and such monies shall be applied by the Trustee to the payment, either directly or through any Paying Agent (including the Company if acting as its own Paying
Agent), to the Holders of the particular Notes for the payment or redemption of which such monies have been deposited with the Trustee, of all sums due and to become due thereon for principal and interest, if any. 
 SECTION 6.03. Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of this Indenture, all monies then held by any Paying Agent
(if 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 6.04. Return of Unclaimed Monies. Subject to the requirements of applicable law, any monies deposited with or paid to the Trustee
for payment of the principal of or interest, if any, on the Notes and not applied but remaining unclaimed by the Holders of the Notes for two years after the date upon which the principal of or interest, if any, on such Notes, as the case may be,
shall have become due and payable, shall be repaid to the Company by the Trustee on demand, and all liability of the Trustee shall thereupon cease with respect to such monies; and the Holder of any of the Notes shall thereafter look only to the
Company for any payment that such Holder of the Notes may be entitled to collect unless an applicable abandoned property law designates another Person. 
 SECTION 6.05. Reinstatement. If the Trustee or the Paying Agent is unable to apply any money in accordance with Section 6.02 by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under the Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 6.01 until such time as the
Trustee or the Paying Agent is permitted to apply all such money in 

  

 35 








 
accordance with Section 6.02; provided, however, that if the Company makes any payment of interest on or principal of any Note following
the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 
 ARTICLE 7 
 SUPPLEMENTAL INDENTURES 
 The supplemental indenture provisions set forth in this Article 7 shall, with respect to the Notes, supersede in its entirety Article IX of the Base
Indenture, and all references in the Base Indenture to Article IX thereof and the supplemental indenture provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 7 and the supplemental
indenture provisions set forth in this Article 7, respectively. 
 SECTION 7.01. Supplemental Indentures Without Consent of Holders.
The Company, when authorized by the resolutions of the Board of Directors, and the Trustee may, from time to time, and at any time enter into an indenture or indentures supplemental hereto for one or more of the following purposes:

agreements and obligations of the Company pursuant to Article VIII of the Base Indenture and Article 9 hereof. 
 (b) to add to the covenants
of the Company such further covenants, restrictions or conditions as the Board of Directors and the Trustee shall consider to be for the benefit of the Holders of Notes, and to make the occurrence, or the occurrence and continuance, of a default in
any such additional covenants, restrictions or conditions a default or an Event of Default permitting the enforcement of all or any of the several remedies provided in this Indenture as herein set forth; provided that in respect of any such
additional covenant, restriction or condition, such supplemental indenture may provide for a particular period of grace after default (which period may be shorter or longer than that allowed in the case of other defaults) or may provide for an
immediate enforcement upon such default or may limit the remedies available to the Trustee upon such default or to surrender any right or power conferred upon the Company; 
 (c) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to the Notes; 
 (d) to modify, eliminate or add to the provisions of the Indenture to such extent as shall be necessary to comply with the requirements of the Commission
or to effect or maintain the qualifications of this Indenture under the Trust Indenture Act, or under any similar federal statute hereafter enacted; 
 (e) subject to the provisions of the Indenture, including Article 8 hereof, to convey, transfer, assign, mortgage or pledge to the Trustee as security for the Notes, any property, assets or securities; 
 (f) to add guarantees with respect to the Notes; 
  

 36 








 (g) to issue Additional Notes in accordance with the provisions of this Indenture; 
 (h) to cure any ambiguity or omission or to correct or supplement any provision contained herein or in any supplemental indenture that may be defective
or inconsistent with any other provision contained herein or in any supplemental indenture; 
 (i) to make such other provisions in regard to
matters or questions arising under this Indenture that shall not adversely affect the rights or interests of the Holders of the Notes in any material respect; or 
 (j) to conform any provision of the Indenture to the “Description of Notes” section of the final prospectus supplement of the Company for the Notes, dated May 21, 2009 and filed with the Commission on
May 22, 2009. 
 Upon the written request of the Company, accompanied by a copy of the resolutions of the Board of Directors certified by its Secretary
or Assistant Secretary authorizing the execution of any supplemental indenture, the Trustee is hereby authorized to join with the Company in the execution of any such supplemental indenture, to make any further appropriate agreements and
stipulations that may be therein contained and to accept the conveyance, transfer and assignment of any property thereunder, but the Trustee shall not be obligated to, but may in its discretion, enter into any supplemental indenture that affects the
Trustee’s own rights, duties or immunities under this Indenture or otherwise. 
 Any supplemental indenture authorized by the provisions of this
Section 7.01 may be executed by the Company and the Trustee without the consent of the Holders of any of the Notes at the time Outstanding, notwithstanding any of the provisions of Section 7.02. 
 SECTION 7.02. Supplemental Indentures With Consent of Holders. With the consent of the Holders of at least a majority in aggregate principal
amount of the Notes at the time Outstanding, the Company, when authorized by the resolutions of the Board of Directors, and the Trustee may, from time to time and at any time, enter into an indenture or indentures supplemental hereto for the purpose
of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or any supplemental indenture or of modifying in any manner the rights of the Holders of the Notes; provided that no such supplemental
indenture shall (i) extend the fixed maturity of any Note, (ii) reduce the rate or extend the time of payment of interest and Additional Interest, if any, of any Note, (iii) reduce the principal amount of any Note, (iv) reduce
any amount payable upon redemption or repurchase of any Note, (v) change the obligation of the Company to redeem any Note on a redemption date in a manner adverse to the Holders of the Notes, (vi) change the obligation of the Company to

right of a Holder to convert any Note into Common Stock or reduce the number of shares of Common Stock or other property receivable upon conversion of the Notes, subject to the terms set forth in the Indenture, including Section 4.06 hereof,
(xi) modify the subordination provisions of this Indenture (including the definition of Senior Indebtedness) in a material respect in a 

  

 37 








 
manner adverse to the Holders of Notes without the consent of the Holder of each Note so affected, (xii) modify any of the provisions of this
Section 7.02 or Sections 512 and 513 of the Base Indenture, except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Note so
affected, (xiii) reduce the quorum or voting requirements or reduce the percentage of Notes, the holders of which are required to consent to any such supplemental indenture, without the consent of the Holders of all Notes then Outstanding.

 Upon the written request of the Company, accompanied by a copy of the resolutions of the Board of Directors certified by its Secretary or Assistant
Secretary authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent Holders as aforesaid, the Trustee shall join with the Company in the execution of such supplemental indenture
unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture.

 It shall not be necessary for the consent of the Holders under this Section 7.02 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the substance thereof. 
 SECTION 7.03. Effect of a Supplemental
Indenture. Any supplemental indenture executed pursuant to the provisions of this Article 7 shall comply with the Trust Indenture Act, as then in effect, provided that this Section 7.03 shall not require such supplemental indenture or the
Trustee to be qualified under the Trust Indenture Act prior to the time such qualification is in fact required under the terms of the Trust Indenture Act or the Indenture has been qualified under the Trust Indenture Act, nor shall it constitute any
admission or acknowledgment by any party to such supplemental 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 or the Indenture has been qualified
under the Trust Indenture Act. Upon the execution of any supplemental indenture pursuant to the provisions of this Article 7, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights,
limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders of Notes shall thereafter be determined, exercised and enforced hereunder, subject in all respects to such modifications and
amendments and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of the Indenture for any and all purposes. 
 SECTION 7.04. Notation on Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of
this Article 7 may bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and
the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may, at the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee (or an Authenticating Agent duly
appointed by the Trustee) and delivered in exchange for the Notes then Outstanding, upon surrender of such Notes then Outstanding. 
  

 38 








 SECTION 7.05. Evidence of Compliance of Supplemental Indenture to be Furnished to Trustee. Prior
to entering into any supplemental indenture, the Trustee shall be provided with an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of
the Indenture and is otherwise authorized or permitted by the Indenture. 
 ARTICLE 8 
 SUBORDINATION OF NOTES 
 The
subordination provisions set forth in this Article 8 shall, with respect to the Notes, supersede in its entirety Article X of the Base Indenture, and all references in the Base Indenture to Article X thereof and the subordination provisions therein,
as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 8 and the subordination provisions set forth in this Article 8, respectively. 
 SECTION 8.01. Notes Subordinate to Senior Indebtedness. The Company covenants and agrees, and each holder of a Note, whether upon original issue
or upon registration of transfer, assignment or exchange hereof, by his acceptance thereof, likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this Article 8, the indebtedness represented by the Notes
and the payment of the principal amount, premium, if any, or interest on all Notes or payment upon a redemption or repurchase at the option of the holder of the Notes and all other amounts and claims owing on and with respect to each and all of the
Notes and all obligations of the Company under this Indenture (collectively, the “Subordinated Obligations”) are hereby expressly made subordinate and junior in right of payment to the prior payment in full in cash or other payment
satisfactory to the holders of Senior Indebtedness of all Senior Indebtedness and that said subordination is for the benefit of the holders of Senior Indebtedness and they and or each of them severally may enforce such subordination. The Notes will
be pari passu in right of payment to all Senior Subordinated Indebtedness of the Company and senior in right of payment to all Subordinated Indebtedness of the Company. 
 SECTION 8.02. Payment Over of Proceeds upon Dissolution, Etc. In the event of (a) any dissolution, insolvency or bankruptcy case or
proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to the Company or to its creditors, as such, or to its assets, or (b) any liquidation, dissolution or other
winding up of the Company, in each case whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or any other marshaling of assets and liabilities of the Company
upon any payment or distribution of the Company’s assets or securities, then and in any such event the holders of Senior Indebtedness shall be entitled to receive payment in full in cash, or other payment satisfactory to the holders of Senior
Indebtedness, of all amounts due or to become due on or in respect of all Senior Indebtedness before the holders of the Notes are entitled to receive any payment or distribution on account of the Subordinated Obligations, and to that end the holders
of Senior Indebtedness or their representative or representatives or the trustee or trustees under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued, shall be entitled to receive from the
liquidating trustee or agent or other Person making such payment or distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee or otherwise, ratably according to the aggregate amounts remaining unpaid on account of the Senior
Indebtedness held or represented by each, to the extent necessary to make payment in full in cash or other 

  

 39 








 
payment satisfactory to the holders of Senior Indebtedness of all Senior Indebtedness remaining unpaid, for application to the payment thereof, any payment
or distribution of any kind or character, whether in cash, property or securities, which may be payable or deliverable in respect of the Subordinated Obligations in any such case, proceeding, dissolution, liquidation or other winding up or event,
assignment or marshalling. 
 The consolidation of the Company with, or the merger of the Company with or into, another Person or the liquidation or
dissolution of the Company following the sale, conveyance, transfer or lease of all or substantially all of its properties and assets to another Person upon the terms and conditions set forth in Article 9 hereof and Article VIII of the Base
Indenture shall not be deemed a dissolution, winding up, liquidation, reorganization, assignment for the benefit of creditors or marshaling of assets and liabilities of the Company for the purposes of this Section 8.02 if the Person formed by
such consolidation or with or into which the Company is merged or which acquires by sale, conveyance, transfer or lease all or substantially all of such properties and assets, as the case may be, shall, as a part of such consolidation, merger, sale,
conveyance, lease or transfer, comply with the conditions set forth in Article 9 hereof and Article VIII of the Base Indenture. 
 SECTION
8.03. No Payment When Senior Indebtedness in Default. 
 (a) The Company may not make any payment of or distribution with respect to
the Subordinated Obligations nor may the Company acquire, defease or redeem any Notes if (i) a payment default on any Senior Indebtedness has occurred and is continuing with respect thereto (unless and until such payment default shall have been
cured or waived in writing by the holders of such Senior Indebtedness); or (ii) a default (other than a default referred to in the preceding clause (i)) on any Designated Senior Indebtedness occurs and is continuing that permits holders of such
Senior Indebtedness to accelerate the maturity thereof and either such default is the subject of judicial proceedings or the Trustee receives a written notice of default thereof that blocks payment under the Notes from any Person who may give such
notice pursuant to the instrument evidencing or document governing such Designated Senior Indebtedness (a “Senior Indebtedness Default Notice”). If the Company receives a Senior Indebtedness Default Notice, then a similar notice
received within nine months thereafter relating to the same default on the same issue of Senior Indebtedness shall not be effective to prevent the payment or acquisition of the Notes for purposes of this Section 8.03. 
 The Company may resume payment on the Notes and may acquire Notes for cash if and when (x) the default referred to in clause (i) or
(ii) of the preceding paragraph above is cured or waived in writing or ceases to exist; or (y) in the case of a default referred to in clause (ii) of the preceding paragraph, 179 or more days pass after the receipt by the Company of
the Senior Indebtedness Default Notice, and this Article 8 otherwise permits the payment or acquisition at that time. 
 Nothing
contained in this Article 8 or elsewhere in this Indenture or in any of the Notes shall prevent the conversion by a holder of any Notes into Common Stock in accordance with the provisions for conversion of such Notes set forth in this
Indenture. 
  

 40 








 (b) In the event of an acceleration of the Notes as a result of an Event of Default, then and in such
event the Company shall promptly notify holders of Senior Indebtedness of such acceleration. The Company may not pay, or make any distribution with respect to, the Notes until the earlier of (i) the passage of 120 or more days have passed after
such acceleration occurs (provided that this clause shall only apply so long as the Company’s 3.50% Convertible Senior Subordinated Debentures due 2024 are outstanding) or (ii) the payment in full in cash or other payment satisfactory to
the holders of Senior Indebtedness of all Senior Indebtedness, and may thereafter pay, or make any distribution with respect to, the Notes if this Article 8 permits the payment or distribution at that time. 
 (c) In the event that, notwithstanding the foregoing provisions, any payment or distribution of any kind or character, whether in cash, property or
securities (including, without limitation, by way of setoff or otherwise), prohibited by this Article 8, shall be received by the Trustee or the holders of the Notes before all Senior Indebtedness is paid in full in cash or other payment
satisfactory to the holders of such Senior Indebtedness, such payment or distribution shall be held in trust for the benefit of and shall be paid over or delivered to the holders of Senior Indebtedness or their representative or representatives, or
to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear for application to the payment of all Senior Indebtedness remaining
unpaid to the extent necessary to pay all Senior Indebtedness in full in cash or other payment satisfactory to the holders of such Senior Indebtedness, after giving effect to any concurrent payment or distribution, or provision therefor, to or for
the holders of such Senior Indebtedness. 
 SECTION 8.04. Payment Permitted If No Default. Nothing contained in this Article 8 or
any other provision relating to subordination elsewhere in this Indenture or in any of the Notes shall prevent the Company, at any time except in the circumstances described in Section 8.02 and Section 8.03, from making payments at any
time of the principal amount of the Notes, interest, the repurchase price with respect to Notes submitted for repurchase in accordance with Section 3.01, as the case may be, as provided in this Indenture. 
 SECTION 8.05. Subrogation to Rights of Holders of Senior Indebtedness. Subject to the payment in full of all Senior Indebtedness in cash, and
until the Notes are paid in full, the holders of the Notes shall be subrogated (equally and ratably with the holders of all Senior Subordinated Indebtedness) to the rights of the holders of such Senior Indebtedness to receive payments and
distributions of cash, property and securities applicable to the Senior Indebtedness to the extent that payments and distributions otherwise payable to holders of Notes have been applied to the payment of Senior Indebtedness as provided by this
Article 8. For purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any cash, property or securities to which the Holders of the Notes or the Trustee would be entitled, except for the
provisions of this Article 8, and no payments over pursuant to the provisions of this Article 8 to the holders of Senior Indebtedness by Holders of the Notes or the Trustee, shall, as among the Company, its creditors other than holders of
Senior Indebtedness and the Holders of the Notes, be deemed to be a payment or distribution by the Company to or on account of the Notes. 
  

 41 








 SECTION 8.06. Provisions Solely To Define Relative Rights. The provisions of this Article 8
are and are intended solely for the purpose of defining the relative rights of the holders of the Notes on the one hand and the holders of Senior Indebtedness on the other hand. Nothing contained in this Article 8 or elsewhere in this Indenture
or in the Notes is intended to or shall (a) impair, as among the Company, its creditors other than holders of Senior Indebtedness and the holders of the Notes, the obligation of the Company, which is absolute and unconditional (and which,
subject to the rights under this Article 8 of the holders of Senior Indebtedness, is intended to rank equally with all other general obligations of the Company), to pay to the holders of the Notes the principal amount of the Notes, interest,
the redemption price with respect to the repurchase price with respect to Notes submitted for repurchase in accordance with Section 3.01, as the case may be, as provided in this Indenture as and when the same shall become due and payable in
accordance with their terms; or (b) affect the relative rights against the Company of the holders of the Notes and creditors of the Company other than the holders of Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Note
from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article 8 of the holders of Senior Indebtedness to receive cash, property and securities otherwise
payable or deliverable to the Trustee or such holder. If the Company fails, as a result of this Article 8, to pay to the holders of the Notes the principal amount of the Notes, interest, the repurchase price with respect to Notes submitted for
repurchase in accordance with Section 3.01, as the case may be, as provided in this Indenture as and when the same shall become due and payable in accordance with their terms, such failure shall still constitute a Default or an Event of
Default. 
 SECTION 8.07. Trustee To Effectuate Subordination. Each holder of a Note by his acceptance thereof authorizes and directs
the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article 8 and appoints the Trustee his attorney-in-fact for any and all such purposes. 
 SECTION 8.08. No Waiver of Subordination Provisions. No right of any present or future holder of any Senior Indebtedness to enforce subordination
as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any non-compliance by the Company with the
terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. 
 Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness may, at any time and from time to time, without the consent of or notice to the Trustee or the holders of the Notes, without incurring
responsibility to the holders of the Notes and without impairing or releasing the subordination provided in this Article 8 or the obligations hereunder of the holders of the Notes to the holders of Senior Indebtedness, do any one or more of the
following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew, exchange, increase or alter, Senior Indebtedness, or otherwise amend, modify or supplement in any manner Senior Indebtedness or any
instrument evidencing the same or any agreement under which Senior Indebtedness or any security thereof or guarantee thereof is outstanding; (ii) sell, exchange, release, surrender, realize upon, enforce or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release any Person liable in any manner for the collection of Senior Indebtedness; (iv) exercise or refrain from exercising any rights against the Company and any 

  

 42 








 
other Person; (v) apply any and all sums received from time to time to the Senior Indebtedness; provided that if any Senior Indebtedness is amended to
provide that it shall be subordinated to any other Senior Indebtedness, such amended Senior Indebtedness shall no longer be considered Senior Indebtedness for purposes of this Article 8. 
 The provisions of this Article 8 shall continue to be effective or be reinstated as the case may be if at any time any payment of the Senior
Indebtedness is rescinded or must otherwise be returned by the holder thereof upon the insolvency, bankruptcy or reorganization of the Company or otherwise, all as though such payment had not been made. 
 SECTION 8.09. Notice to Trustee. The Company shall give prompt written notice to a Responsible Officer of the Trustee of any fact known to the
Company which would prohibit the making of any payment to or by the Trustee in respect of the Notes. Notwithstanding the provisions of this Article 8 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts which would prohibit the making of any payment to or distribution by the Trustee in respect of the Notes, unless and until a Responsible Officer of the Trustee shall have received written notice thereof from the Company or
a holder of Senior Indebtedness or from any trustee therefor; and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of Section 601 of the Base Indenture, shall be entitled in all respects to assume that no
such facts exist; provided, however, that if the Trustee shall not have received the notice provided for in this Section 8.09 at least two Business Days prior to the date upon which by the terms hereof any money may become payable for any
purpose, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purpose for which such money was received and shall not be affected by any
notice to the contrary which may be received by it within two Business Days prior to such date. 
 Subject to the provisions of the
Indenture, the Trustee shall be entitled to rely conclusively on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Indebtedness (or a trustee therefor) to establish that such notice has been given by a
holder of Senior Indebtedness (or a trustee therefor). In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment
or distribution pursuant to this Article 8 (although the Trustee is not obligated to make such determination), the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior
Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article 8, and if such evidence is not furnished,
the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 
 SECTION 8.10. Reliance on Judicial Order or Certificate of Liquidating Agent. Upon any payment or distribution of assets of the Company referred to in this Article 8, the Trustee, subject to the provisions of the Indenture, and
the holders of the Notes shall be entitled to conclusively rely upon any order or decree entered by any court of competent jurisdiction in which such insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or
similar case or proceeding is pending, or a certificate 

  

 43 








 
of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other Person making such payment or
distribution, delivered to the Trustee or to the holders of Notes, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the
amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 8. 
 SECTION 8.11. Trustee Not Fiduciary for Holders of Senior Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and (subject to Section 8.09 hereof)
shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute to holders of Notes or to the Company or to any other Person cash, property or securities to which any holders of Senior Indebtedness shall be
entitled by virtue of this Article 8 or otherwise. 
 SECTION 8.12. Rights of Trustee as Holder of Senior Indebtedness; Preservation
of Trustee’s Rights. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article 8 with respect to any Senior Indebtedness which may at any time be held by it, to the same extent as any other
holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. 
 Nothing in
this Article 8 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 607 of the Base Indenture. 
 SECTION 8.13. Article Applicable to Paying Agents. In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this
Article 8 shall in such case (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article 8
in addition to or in place of the Trustee; provided, however, that Section 8.12 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. 
 SECTION 8.14. No Senior Subordinated Indebtedness. The Company shall not, directly or indirectly, create, incur, issue, assume, guarantee or
otherwise become directly or indirectly liable, contingently or otherwise, with respect to any indebtedness that is subordinate or junior in right of payment to any Senior Indebtedness and senior in right of payment to the Notes. 
 SECTION 8.15. Amendment of Subordination Provisions. Any Senior Indebtedness will continue to be Senior Indebtedness and will be entitled to the
benefits of the subordination provisions of this Article 8 irrespective of any amendment, modification or waiver of any of such subordination provisions.

Person or sell, convey, transfer or lease all or substantially all of its properties and assets to any Person, unless: 
  

	 	(1)	in case the Company shall consolidate with or merge with or into another Person or sell, convey, transfer or lease all or substantially all of its properties and assets to any
Person, the Person formed by such consolidation or with or into which the Company is merged or the Person which acquires by sale, conveyance or transfer, or which leases, all or substantially all of the properties and assets of the Company shall be
a corporation, partnership or trust, shall be organized and validly existing under the laws of the United States of America, any State thereof or the District of Columbia and shall expressly assume, by an indenture supplemental hereto,
executed and delivered to the Trustee, in form satisfactory to the Trustee, the due and punctual payment of the principal of and any premium and interest on all the Notes and the performance or observance of every covenant of this Subordinated
Indenture on the part of the Company to be performed or observed; 

  

	 	(2)	immediately after giving effect to such transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have
happened and be continuing; and 

  

	 	(3)	the Company or the successor Person has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale,

 MISCELLANEOUS 
 SECTION 10.01. Withholding Offset. (a) The Company (through the
Withholding Agent or otherwise) shall be entitled to reduce or otherwise set-off against any payments made or deemed made by the Company to Holders in respect of the Notes or the Common Stock for any amounts the Company believes it is required to
withhold by law. For the avoidance of doubt, if the Company pays any withholding taxes on behalf of a Holder as a result of an adjustment to the Conversion Rate of the Notes, the Company may, at its option, set-off such payments against payments to
such Holder of cash and Common Stock in respect of the Notes. Any amounts withheld pursuant to this Section 10.01 shall be paid over by the Company (through the Withholding Agent or otherwise) to the appropriate taxing authority. 
  

 45 








 (b) Prior to or upon the occurrence of any event that results in an actual or deemed payment by the
Company to Holders in respect of the Notes or the Common Stock, the Company (through the Trustee, Paying Agent, Withholding Agent, or otherwise) may request a Holder to furnish any appropriate documentation that may be required in order to determine
the Company’s withholding obligations under applicable law (including, without limitation, a United States Internal Revenue Service Form W-9, Form W-8BEN or Form W-8ECI), as appropriate.

 SECTION 10.04. No Security Interest Created. Nothing in this Supplemental Indenture or in the Notes, expressed or implied, shall be construed to
constitute a security interest under the Uniform Commercial Code or similar legislation, as now or hereafter enacted and in effect, in any jurisdiction. 
 SECTION 10.05. Trust Indenture Act. This Supplemental Indenture is hereby made subject to, and shall be governed by, the provisions of the Trust Indenture Act required to be part of and to govern indentures
qualified under the Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with another provision hereof or the Base Indenture that is required to be included in an indenture qualified under the Trust Indenture Act, such
required provision shall control. 
 SECTION 10.06. Benefits of Indenture. Nothing in this Supplemental Indenture or in the Notes,
expressed or implied, shall give to any Person, other than the parties hereto, any Paying Agent, any Conversion Agent, any authenticating agent, any Registrar and their successors hereunder or the Holders of the Notes, any benefit or any legal or
equitable right, remedy or claim under this Supplemental Indenture.

a schedule of its calculations to each of the Trustee and the Conversion Agent (if different than the Trustee), and each of the Trustee and Conversion Agent (if different than the Trustee) is entitled to rely conclusively upon the accuracy of the
Company’s calculations without independent verification. The Trustee will forward the Company’s calculations to any Holder of Notes upon the request of that Holder. 
 SECTION 10.08. Table of Contents, Headings, Etc. The table of contents and the titles and headings of the articles and sections of this
Supplemental Indenture have been inserted for convenience of reference only, are not to be considered a part hereof, and shall in no way modify or restrict any of the terms or provisions hereof.

number of counterparts, each of which shall be an original, but such counterparts shall together constitute but one and the same instrument. 
 SECTION 10.10. Severability. In the event any provision of this Supplemental Indenture or in the Notes shall be invalid, illegal or unenforceable, then (to the extent permitted by law) the validity, legality or enforceability of the

Paying Agent or Registrar for the Notes without prior notice to the Holders thereof, and the Company may act as Paying Agent or Registrar. Interest on the Notes (other than Notes that are Global Notes) will be payable (i) to Holders of the
Notes having an aggregate principal amount of Notes of $5,000,000 or less, by check mailed to the Holders of these Notes at their address in the Security Register and (ii) to Holders having an aggregate principal amount of Notes in excess of
$5,000,000, either by check mailed to each Holder at its address in the Security Register or, upon application by a Holder to the Registrar not later than the relevant Regular

 [FORM OF REVERSE OF NOTE] 
 COMMSCOPE, INC. 
 3.25% Senior Subordinated Convertible Notes due 2015

of May 28, 2009, as supplemented from time to time in accordance with the terms thereof (herein called the “Base Indenture”) and as further supplemented by the Supplemental Indenture dated as of May 28, 2009 (herein called
the “Supplemental Indenture” and the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”) by and between the Company and U.S. Bank National Association, herein called the
“Trustee”, and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms
upon which the Notes are, and are to be, authenticated and delivered. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. 
 This Note is not subject to the provisions of Article XII or XIII of the Base Indenture. The provisions in Article 6 of the Supplemental Indenture
supersede the entirety of Articles IV and XIV of the Base Indenture. The provisions in Article 7 of the Supplemental Indenture supersede the entirety of Article IX of the Base Indenture. The provisions in Article 8 of the Supplemental Indenture
supersede the entirety of Article X of the Base Indenture. 
 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 Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Purchase Date at a price equal to the
Fundamental Change Purchase Price. 
 As provided in and subject to the provisions of the Indenture, the Holder hereof has the right, at its
option prior to the close of business on the second Scheduled Trading Day immediately preceding July 1, 2015, to convert this Note or a portion thereof that is $1,000 or an integral multiple thereof, into shares of Common Stock at the
applicable Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture. 
 As provided in and
subject to the provisions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Purchase Price and the principal amount on the Stated Maturity thereof, as the case may be, to the holder who
surrenders a Note to the Paying Agent to collect such payments in respect of the Note. 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 permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Notes to be effected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time Outstanding. The Indenture
also contains provisions permitting the Holders of specified percentages in principal amount of the Notes at the time Outstanding, on behalf of the Holders of all Notes, to waive compliance by the Company with certain provisions of the Indenture and
certain past

defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder
and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 
 As provided in and subject to the provisions of the Indenture, in case an Event of Default, as defined in the Indenture, shall have occurred and be
continuing, the principal of and interest on all Notes may be declared due and payable, by either the Trustee or Holders of not less than 25% in aggregate principal amount of 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; provided that upon the occurrence of an Event of Default with respect to the Company specified in Section 5.01(i) or (j) of the
Supplemental Indenture, the principal amount of, and interest on, all the Notes shall automatically become due and payable. 
 No reference
herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Note at the time, place
and rate, and in the coin and currency, herein prescribed. 
 As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Note is registrable in the Security Register, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Note are payable, duly
endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of this series
and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Notes are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, the Notes
are exchangeable for a like aggregate principal amount of Notes and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 
 No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this Note for registration of transfer, the
Company, the Trustee and any agent of the Company or Trustee may treat the Person in whose name the Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent
