required by this Indenture. 
  
 Notes may be exchanged for other
Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency maintained by the Company pursuant to Section 5.02 hereof. Whenever any Notes are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes which the Noteholder making the exchange is entitled to receive bearing registration numbers not contemporaneously outstanding. 
  
 All Notes issued upon any registration of transfer or exchange of Notes shall
be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange. 
  
 All Notes presented or surrendered for registration of transfer or for
exchange, purchase following a Fundamental Change or conversion shall (if so required by the Company or the Note registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company,
and the Notes shall be duly executed by the Noteholder thereof or his attorney duly authorized in writing. 
  
 No service charge shall be made to any holder for any registration of transfer or exchange of Notes, but the Company may require payment by the holder of
a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes. 
  
 Neither the Company nor the Trustee nor any Note registrar shall be required to exchange or register a transfer of (a) any
Notes or portions thereof surrendered for conversion pursuant to Article 15 or (b) any Notes or portions thereof tendered for purchase (and not withdrawn) pursuant to Section 3.02 hereof. 
  
 (b) So long as the Notes are eligible for book-entry settlement with the Depositary, or unless otherwise required by law,
all of the Notes will be 
  

 15 

 represented by one or more Notes in global form registered in the name of the Depositary or the nominee of the Depositary
(the “Global Note”), except as otherwise specified below. The transfer and exchange of beneficial interests in any such Global Note shall be effected through the Depositary in accordance with this Indenture and the procedures of the
Depositary therefor. The Trustee shall make appropriate endorsements to reflect increases or decreases in the principal amounts of any such Global Note as set forth on the face of the Note (“Principal Amount”) to reflect any such
transfers. Except as provided below, beneficial owners of a Global Note shall not be entitled to have certificates registered in their names, will not receive or be entitled to receive physical delivery of certificates in definitive form and will
not be considered holders of such Global Note. 
  
 (c) Any Global
Note may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of this Indenture as may be required by the Custodian, the Depositary or by the National Association of
Securities Dealers, Inc. in order for the Notes to be tradeable on The Portal Market or as may be required for the Notes to be tradeable on any other market developed for trading of securities pursuant to Rule 144A or required to comply with any
applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or automated quotation system upon which the Notes may be listed or traded or to conform with any usage with respect thereto, or to indicate any
special limitations or restrictions to which any particular Notes are subject. 
  
 (d) Every Note that bears or is required under this Section 2.05(d) to bear the legend set forth in this Section (together with any Common Stock issued upon conversion of the Notes and required to bear the legend set
forth in Section 2.05(e) hereof, collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(d) (including those set forth in the legend set forth below) unless such
restrictions on transfer shall be waived by written consent of the Company, and the holder of each such Restricted Security, by such Noteholder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in Sections
2.05(d) and 2.05(e) hereof, the term “transfer” encompasses any sale, pledge, loan, transfer or other disposition whatsoever of any Restricted Security. 
  
 Until the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any
successor provision), any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof, which shall bear the legend set forth in Section
2.05(e) hereof, if applicable) shall bear a legend in substantially the following form, unless such Note has been sold pursuant to a registration statement that has been declared 
  

 16 

 effective under the Securities Act (and which continues to be effective at the time of such transfer), or unless
otherwise agreed by the Company in writing, with written notice thereof to the Trustee: 
  
 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”). THE HOLDER HEREOF, BY PURCHASING THIS SECURITY, AGREES FOR THE BENEFIT OF THE COMPANY THAT
THIS SECURITY MAY NOT BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED (X) PRIOR TO THE EXPIRATION OF THE HOLDING PERIOD UNDER RULE 144(K) (OR ANY SUCCESSOR THERETO) UNDER THE SECURITIES ACT WHICH IS APPLICABLE TO THIS SECURITY OR (Y) BY ANY HOLDER THAT
WAS AN “AFFILIATE” (WITHIN THE MEANING OF RULE 144 UNDER THE SECURITIES ACT) OF THE COMPANY AT ANY TIME DURING THE THREE MONTHS PRECEDING THE DATE OF SUCH TRANSFER, IN EITHER CASE, OTHER THAN (1) TO THE COMPANY, (2) SO LONG AS THIS
SECURITY IS ELIGIBLE FOR RESALE PURSUANT TO RULE 144A UNDER THE SECURITIES ACT (“RULE 144A”), TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A, PURCHASING FOR ITS OWN
ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE RESALE, PLEDGE OR OTHER TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (3) TO AN INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS
DEFINED IN RULE 501(A)(1), (2) OR (7) UNDER THE SECURITIES ACT (“INSTITUTIONAL ACCREDITED INVESTOR”), (4) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT, INCLUDING THE EXEMPTION PROVIDED BY RULE
144 (IF APPLICABLE) OF THE SECURITIES ACT OR (5) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH CASE IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. PRIOR TO A TRANSFER OF THIS
SECURITY (OTHER THAN A TRANSFER PURSUANT TO CLAUSE (5) ABOVE), THE HOLDER OF THIS SECURITY MUST FURNISH TO THE COMPANY AND THE TRANSFER AGENT SUCH CERTIFICATES AND 
  

 17 

 OTHER INFORMATION AND LEGAL OPINIONS AS THEY MAY REASONABLY REQUIRE. THE HOLDER HEREOF, BY PURCHASING
THIS SECURITY, REPRESENTS AND AGREES FOR THE BENEFIT OF THE COMPANY THAT IT IS (1) A QUALIFIED INSTITUTIONAL BUYER OR (2) AN INSTITUTIONAL ACCREDITED INVESTOR AND THAT IT IS HOLDING THIS SECURITY FOR INVESTMENT PURPOSES AND NOT FOR DISTRIBUTION. IN
ANY CASE THE HOLDER HEREOF WILL NOT, DIRECTLY OR INDIRECTLY, ENGAGE IN ANY HEDGING TRANSACTION WITH REGARD TO THIS SECURITY OR ANY COMMON STOCK ISSUABLE UPON CONVERSION OF THIS SECURITY EXCEPT AS PERMITTED BY THE SECURITIES ACT. 
  
 Any Note (or security issued in exchange or substitution therefor) as to
which such restrictions on transfer shall have expired in accordance with their terms or as to which conditions for removal of the foregoing legend set forth therein have been satisfied may, upon surrender of such Note for exchange to the Note
registrar in accordance with the provisions of this Section 2.05 be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.05(d). 
  
 Notwithstanding any other provisions of this Indenture (other than the
provisions set forth in the second paragraph of Section 2.05(a) hereof and in this Section 2.05(d)), a Global Note may not be transferred as a whole or in part except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary
to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. 
  
 The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository
Trust Company to act as Depositary with respect to the Notes in global form. Initially, the Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Custodian
for Cede & Co. 
  
 If at any time the Depositary for a Global
Note notifies the Company that it is unwilling or unable to continue as Depositary for such Note, the Company may appoint a successor Depositary with respect to such Note. If a successor Depositary is not appointed by the Company within 90 days
after the Company receives such notice, the Company will execute, and the Trustee, upon receipt of an Officers’ Certificate for the authentication and delivery of Notes, will authenticate and deliver, Notes in certificated form, in aggregate
principal amount equal to the principal amount of such Global Note, in exchange for such Global Note. 
  

 18 

 Notes in certificated form issued in exchange for a Global Note pursuant to this Section 2.05 shall be
registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver
such Notes in certificated form to the Persons in whose names such Notes in certificated form are so registered. 
  
 At such time as all interests in a Global Note have been redeemed, converted, canceled or the Global Note is exchanged for Notes in certificated form,
such Global Note shall, upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global
Note is redeemed, converted, repurchased or canceled, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or
increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase. 
  
 (e) Until the expiration of the holding period applicable to sales thereof
under Rule 144(k) under the Securities Act (or any successor provision), any stock certificate representing Common Stock issued upon conversion of any Note shall bear a legend in substantially the following form, unless such Common Stock has been
sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer) or such Common Stock has been issued upon conversion of Notes that have been
transferred pursuant to a registration statement that has been declared effective under the Securities Act, or unless otherwise agreed by the Company in writing with written notice thereof to the transfer agent: 
  
 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE “SECURITIES ACT”). THE HOLDER HEREOF, BY PURCHASING THIS SECURITY, AGREES FOR THE BENEFIT OF THE COMPANY THAT THIS SECURITY MAY NOT BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED (X) PRIOR TO THE EXPIRATION OF THE HOLDING
PERIOD UNDER RULE 144(K) (OR ANY SUCCESSOR THERETO) UNDER THE SECURITIES ACT WHICH IS APPLICABLE TO THIS SECURITY OR (Y) BY ANY HOLDER THAT WAS AN “AFFILIATE” (WITHIN THE 
  

 19 

 MEANING OF RULE 144 UNDER THE SECURITIES ACT) OF THE COMPANY AT ANY TIME DURING THE THREE MONTHS
PRECEDING THE DATE OF SUCH TRANSFER, IN EITHER CASE, OTHER THAN (1) TO THE COMPANY, (2) TO AN INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(A)(1), (2) OR (7) UNDER THE SECURITIES ACT (“INSTITUTIONAL
ACCREDITED INVESTOR”) (AS INDICATED BY THE BOX CHECKED BY THE TRANSFEROR ON THE CERTIFICATE OF TRANSFER APPLICABLE TO THIS SECURITY, THE FORM OF WHICH MAY BE OBTAINED FROM THE COMPANY OR THE TRANSFER AGENT), (3) PURSUANT TO ANOTHER
AVAILABLE EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT, INCLUDING THE EXEMPTION PROVIDED BY RULE 144 (IF APPLICABLE) UNDER THE SECURITIES ACT (AS INDICATED BY THE BOX CHECKED BY THE TRANSFEROR ON THE CERTIFICATE OF TRANSFER APPLICABLE TO
THIS SECURITY, THE FORM OF WHICH MAY BE OBTAINED FROM THE COMPANY OR THE TRANSFER AGENT) OR (4) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH CASE IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF
THE UNITED STATES. PRIOR TO A TRANSFER OF THIS SECURITY (OTHER THAN A TRANSFER PURSUANT TO CLAUSE (4) ABOVE), THE HOLDER OF THIS SECURITY MUST FURNISH TO THE COMPANY AND THE TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AND LEGAL OPINIONS
AS THEY MAY REASONABLY REQUIRE. THE HOLDER HEREOF, BY PURCHASING THIS SECURITY, REPRESENTS AND AGREES FOR THE BENEFIT OF THE COMPANY THAT IT IS AN INSTITUTIONAL ACCREDITED INVESTOR AND THAT IT IS HOLDING THIS SECURITY FOR INVESTMENT PURPOSES AND NOT
FOR DISTRIBUTION. IN ANY CASE, THE HOLDER HEREOF WILL NOT, DIRECTLY OR INDIRECTLY, ENGAGE IN ANY HEDGING TRANSACTION WITH REGARD TO THIS SECURITY EXCEPT AS PERMITTED BY THE SECURITIES ACT. 
  
 Any such Common Stock as to which such restrictions on transfer shall have
expired in accordance with their terms or as to which the conditions for removal of the foregoing legend set forth therein have been satisfied may, upon 
  

 20 

 surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of
the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like number of shares of Common Stock, which shall not bear the restrictive legend required by this Section 2.05(e). 
  
 (f) Any Note or Common Stock issued upon the conversion or exchange of a Note
that, prior to the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), is purchased or owned by the Company or any Affiliate thereof may not be resold by the Company
or such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction which results in such Notes or Common Stock, as the case may be, no longer
being “restricted securities” (as defined under Rule 144). 
  
 Section 2.06 Mutilated, Destroyed, Lost Or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an
authenticating agent appointed by the Trustee shall authenticate and make available for delivery, a new Note, bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution
for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save
each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to
such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof. 
  
 Following receipt by the Trustee or such authenticating agent, as the case may be, of satisfactory security or indemnity and evidence, as described in
this Section 2.06, the Trustee or such authenticating agent may authenticate any such substituted Note and make available for delivery such Note. Upon the issuance of any substituted Note, the Company may require the payment by the holder of a sum
sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note which has matured or is about to mature or has been tendered for purchase
following a Fundamental Change (and not withdrawn) or is to be converted into Common Stock shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Note, pay or authorize the payment of or convert or
authorize the conversion of the same (without 
  

 21 

 surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or
conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or
connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, the Trustee and, if applicable, any paying agent or conversion agent evidence to their satisfaction of the
destruction, loss or theft of such Note and of the ownership thereof. 
  
 Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the
destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued
hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion of mutilated, destroyed, lost or stolen
Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities
without their surrender. To the extent permitted by law, a Note that has been mutilated, destroyed, lost or stolen, and for which either a substituted Note has been issued or for which payment or conversion has been made or authorized, shall cease
to be a binding obligation of the Company. 
  
 Section 2.07
Temporary Notes. Pending the preparation of Notes in certificated form, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon the written request of the Company, authenticate and deliver
temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Notes in certificated form, but with such omissions, insertions and variations as may be appropriate
for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and
with the same effect, as the Notes in certificated form. Without unreasonable delay the Company will execute and deliver to the Trustee or such authenticating agent Notes in certificated form and thereupon any or all temporary Notes may be
surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 5.02 hereof and the Trustee or such authenticating agent shall authenticate and make available for delivery in exchange for such temporary Notes
an equal aggregate principal amount of Notes in certificated form. Such exchange shall be 
  

 22 

 made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in
all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Notes in certificated form authenticated and delivered hereunder. 
  
 Section 2.08 Cancellation Of Notes Paid, Etc. All Notes surrendered for the purpose of payment, purchase following a
Fundamental Change, conversion, exchange or registration of transfer shall, if surrendered to the Company or any paying agent or any Note registrar or any conversion agent, be surrendered to the Trustee and promptly canceled by it, or, if
surrendered to the Trustee, shall be promptly canceled by it, and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of such canceled Notes in accordance with
its customary procedures. If the Company shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for
cancellation. 
  
 Section 2.09 Cusip Numbers. The Company
in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of purchase following a Fundamental Change as a convenience to Noteholders; provided,
however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a purchase following a Fundamental Change and that reliance may be
placed only on the other identification numbers printed on the Notes, and any such purchase following a Fundamental Change shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change
in the “CUSIP” numbers. 
  
 ARTICLE 3 
 REDEMPTION OF NOTES 
  

Section 3.01 Prohibition on Redemption. The Notes may not be redeemed by the Company, in whole or in part, prior to the final maturity date of
the Notes except to the extent that a purchase pursuant to Section 3.02 may be deemed a redemption. Nothing herein shall prevent the Company or any of its Subsidiaries from tendering for or repurchasing any Notes, subject to applicable laws.

  
 Section 3.02 Fundamental Change. (a) If there shall
occur a Fundamental Change at any time prior to maturity of the Notes, then each Noteholder shall have the right, at such holder’s option, to require the Company to purchase all of such holder’s Notes, or any portion thereof that is an
integral 
  

 23 

 multiple of $1,000 principal amount, for cash, on the date (the “Purchase Date”) that is 30 days after
the date of the Company Notice (as defined in Section 3.02(b) hereof) of such Fundamental Change (or, if such 30th day is not a Business Day, the next succeeding Business Day) at a purchase price equal to 100% of the principal amount thereof, plus
accrued but unpaid interest, and Liquidated Damages, if any, to (but excluding) the Purchase Date; provided, however, that, if such Purchase Date is a June 30 or December 30, then the interest payable on such date shall be paid to the
holders of record of the Notes on the next preceding June 15 or December 15, respectively. 
  
 If there shall have occurred a Fundamental Change and at least sixty percent (60%) of the consideration for the Common Stock in the transaction or transactions constituting the Fundamental Change consists of cash (a
“Cash Buy-Out”), the Company will pay a Make-Whole Premium to the holders of Notes in addition to the purchase price. If a holder surrenders its Notes (or any portion thereof) for conversion after receipt of a Company Notice and
prior to the Purchase Date, and the Fundamental Change related to the Company Notice constitutes a Cash Buy-Out, the Company will pay a Make-Whole Premium to such holder, in addition to the shares of Common Stock deliverable upon conversion of the
Notes. 
  
 The “Make-Whole Premium” per Note will equal
(a) the average of the Closing Trading Prices of a Note for the five Trading Days immediately prior to the Public Announcement Date of the Cash Buy-Out, less (b) the greater of (i) $1,000 or (ii) the product of (x) the average Closing Prices of the
Common Stock for the five Trading Days immediately prior to the Public Announcement Date of the Cash Buy-Out and (y) the applicable Conversion Rate; and will be payable in cash. The Make-Whole Premium, if any, will not be less than zero. 

 
 Whenever in this Indenture (including Section 2.02, Section 7.01(b) and
Section 4.03 hereof) or in the Notes there is a reference, in any context, to the principal of any Note as of any time, such reference shall be deemed to include reference to the purchase price, payable in respect to such Note to the extent that
such purchase price is, was or would be so payable at such time, and express mention of the purchase price in any provision of this Indenture or in the Notes shall not be construed as excluding the purchase price in those provisions of this
Indenture when such express mention is not made. 
  
 Upon
presentation of any Note redeemed in part only, the Company shall execute and, upon the Company’s written direction to the Trustee, 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 principal amount equal to the unredeemed portion of the Notes so presented. 
  

 24 

 (b) On or before the 10th day after the occurrence of a Fundamental Change, the Company or at its written
request (which must be received by the Trustee at least five Business Days prior to the date the Trustee is requested to give notice as described below, unless the Trustee shall agree in writing to a shorter period), the Trustee, in the name of and
at the expense of the Company, shall mail or cause to be mailed to all holders of record on the date of the Fundamental Change a notice (the “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 mailed by the Company or by the Trustee in the name of and at the expense of the Company to the holders of Notes at their last addresses as the same appear on the Note
register. Such mailing shall be by first class mail. The notice if mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the holder receives such notice. In any case, failure to give such notice
by mail or any defect in the notice to the holder of any Note shall not affect the validity of the proceedings for the purchase of any other Note. If the Company shall give such notice, the Company shall also deliver a copy of the Company Notice to
the Trustee at such time as it is mailed to Noteholders. Concurrently with or before the mailing of any Company Notice, the Company shall issue a press release announcing such Fundamental Change referred to in the Company Notice, the form and
content of which press release shall be determined by the Company in its sole discretion. The failure to issue any such press release or any defect therein shall not affect the validity of the Company Notice or any proceedings for the purchase of
any Note which any Noteholder may elect to have the Company purchase as provided in this Section 3.02. 
  
 Each Company Notice shall specify the circumstances constituting the Fundamental Change, the Purchase Date, the price at which the Company shall be
obligated to purchase Notes, whether a Make-Whole Premium shall be paid by the Company, that the holder must exercise the purchase right prior to the close of business on the Purchase Date (the “Fundamental Change Expiration Time”),
that the holder shall have the right to withdraw any Notes surrendered prior to the Fundamental Change Expiration Time, a description of the procedure which a Noteholder must follow to exercise such purchase right and to withdraw any surrendered
Notes, the place or places where the holder is to surrender such holder’s Notes, the amount of interest, and Liquidated Damages, if any, accrued on each Note to the Purchase Date and the “CUSIP” number or numbers of the Notes (if then
generally in use). 
  
 No failure of the Company to give the
foregoing notices and no defect therein shall limit the Noteholders’ purchase rights or affect the validity of the proceedings for the purchase of the Notes pursuant to this Section 3.02. 
  

 25 

 (c) For a Note to be so redeemed at the option of the holder, the Company must receive at the office or
agency of the Company maintained for that purpose or, at the option of such holder, the Corporate Trust Office, such Note with the form entitled “Option to Elect Repayment Upon A Fundamental Change” on the reverse thereof duly
completed, together with such Notes duly endorsed for transfer, on or before the Fundamental Change Expiration Time. All questions as to the validity, eligibility (including time of receipt) and acceptance of any Note for repayment shall be
determined by the Company, whose determination shall be final and binding absent manifest error. 
  
 (d) On or prior to the Purchase Date, the Company will deposit with the Trustee or with one or more paying agents (or, if the Company is acting as its own
paying agent, set aside, segregate and hold in trust as provided in Section 5.04 hereof) an amount of money sufficient to purchase on the Purchase Date (including such amount with respect to a Make-Whole Premium, if any) all the Notes that have been
surrendered in accordance with Section 3.02(c) hereof at least three Business Days in advance of the Purchase Date at the appropriate purchase price, together with accrued interest and Liquidated Damages, if any, to (but excluding) the Purchase
Date; provided, however, that if such payment is made on the Purchase Date it must be received by the Trustee or paying agent, as the case may be, by 10:00 a.m. New York City time, on such date. An amount of money sufficient to pay the
purchase price (including such amount with respect to a Make-Whole Premium, if any) and accrued interest and Liquidated Damages, if any, for the balance of the Notes to be redeemed on the Purchase Date shall subsequently be deposited with the
Trustee. Payment for Notes surrendered for purchase (and not withdrawn) prior to the Fundamental Change Expiration Time will be made promptly (but in no event more than five Business Days) following the Purchase Date by mailing checks for the amount
payable to the holders of such Notes entitled thereto as they shall appear on the registry books of the Company. 
  
 (e) In the case of a reclassification, change, consolidation, merger, combination, sale or conveyance to which Section 15.07 hereof applies, in which the
Common Stock of the Company is changed or exchanged as a result into the right to receive stock, securities or other property or assets (including cash), which includes shares of Common Stock of the Company or shares of common stock of another
Person that are, or upon issuance will be, traded on a United States national securities exchange, the London Stock Exchange, the Tokyo Stock Exchange or the German Stock Exchange, or approved for quotation on the Nasdaq National Market or any
similar United States system of automated dissemination of quotations of securities prices, or approved for trading on an established automated over-the-counter trading market in the United States and such shares constitute at the time such change
or exchange becomes effective in excess of 50% of the aggregate fair market value of such stock, securities or other 
  

 26 

 property or assets (including cash) (as determined by the Company, which determination shall be conclusive and binding),
then the Person formed by such consolidation or resulting from such merger or which acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture (accompanied by an Opinion of Counsel that such
supplemental indenture complies with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) modifying the provisions of this Indenture relating to the right of holders of the Notes to cause the Company to
repurchase the Notes following a Fundamental Change, including without limitation the applicable provisions of this Section 3.02 and the definitions of Common Stock and Fundamental Change, as appropriate, as determined in good faith by the Company
(which determination shall be conclusive and binding), to make such provisions apply to such other Person if different from the Company and the common stock issued by such Person (in lieu of the Company and the Common Stock of the Company).

  
 (f) The Company will comply with the provisions of Rule 13e-4
and any other tender offer rules under the Exchange Act to the extent then applicable in connection with the purchase rights of the holders of Notes in the event of a Fundamental Change. 
  
 ARTICLE 4 
 SUBORDINATION OF NOTES 
  
 Section 4.01 Agreement of Subordination. The Company covenants and agrees, and each holder of Notes issued hereunder by its acceptance thereof likewise covenants and agrees, that all Notes shall be issued
subject to the provisions of this Article 4 and each Person holding any Note, whether upon original issue or upon registration of transfer, assignment or exchange thereof, accepts and agrees to be bound by such provisions. 
  
 The payment of the principal of, premium, if any, and interest (including
Liquidated Damages, if any) on all Notes (including, but not limited to, the purchase price with respect to the Notes submitted for purchase in accordance with Section 3.02 hereof, as provided in this Indenture) issued hereunder shall, to the extent
and in the manner hereinafter set forth, be subordinated and subject in right of payment to the prior payment in full of all Senior Indebtedness, whether outstanding at the date of this Indenture or thereafter incurred. 
  
 No provision of this Article 4 shall prevent the occurrence of any default or
Event of Default hereunder. 
  

 27 

 Section 4.02 Payments To Noteholders. No payment shall be made with respect to the principal of,
premium, if any, or interest (including Liquidated Damages, if any) on the Notes (including, but not limited to, the purchase price with respect to the Notes submitted for purchase in accordance with Section 3.02 hereof, as provided in this
Indenture), except payments and distributions made by the Trustee as permitted by Section 4.05 hereof, if: 
  
 (i) a default in the payment of principal, premium, if any, interest, rent or other obligations in respect of Designated Senior
Indebtedness occurs and is continuing (or, in the case of Designated Senior Indebtedness for which there is a period of grace, in the event of such a default that continues beyond the period of grace, if any, specified in the instrument or lease
evidencing such Designated Senior Indebtedness) (a “Payment Default”), unless and until such Payment Default shall have been cured or waived or shall have ceased to exist; or 
  
 (ii) a default, other than a Payment Default, on any
Designated Senior Indebtedness occurs and is continuing that then permits holders of such Designated Senior Indebtedness to accelerate its maturity (or in the case of any lease, a default occurs and is continuing that permits the lessor to either
terminate the lease or require the Company to make an irrevocable offer to terminate the lease following an event of default thereunder) and the Trustee receives a notice of the default (a “Payment Blockage Notice”) from a holder of
Designated Senior Indebtedness, a Representative of Designated Senior Indebtedness or the Company (a “Non-Payment Default”). 
  
 If the Trustee receives any Payment Blockage Notice pursuant to clause (ii) above, no subsequent Payment Blockage Notice shall be effective for purposes
of this Section 4.02 unless and until at least 365 days shall have elapsed since the initial effectiveness of the immediately prior Payment Blockage Notice. No Non-Payment Default that existed or was continuing on the date of delivery of any Payment
Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent Payment Blockage Notice. 
  
 The Company may and shall resume payments on and distributions in respect of the Notes upon the earlier of: 
  
 (1) the date upon which any such Payment Default is cured or
waived or ceases to exist, or 
  
 (2) in the case
of a Non-Payment Default, the earlier of (a) the date upon which such default is cured or waived or ceases to exist or (b) 179 days after the applicable Payment Blockage Notice is received by the Trustee if the maturity of such Designated Senior
Indebtedness has not 
  

 28 

 been accelerated (or in the case of any lease, 179 days after such notice is received if the Company has
not received notice that the lessor under such lease has exercised its right to terminate the lease or require the Company to make an irrevocable offer to terminate the lease following an event of default thereunder), unless this Article 4 otherwise
prohibits the payment or distribution at the time of such payment or distribution. 
  
 Upon any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon any dissolution or winding up or liquidation or
reorganization of the Company, whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceedings, all amounts due or to become due upon all Senior Indebtedness shall first be paid in full in cash or other payment
satisfactory to the holders of such Senior Indebtedness, or payment thereof in accordance with its terms provided for in cash or other payment satisfactory to the holders of such Senior Indebtedness before any payment is made on account of the
principal of, premium, if any, or interest (including Liquidated Damages, if any) on the Notes (except payments made pursuant to Article 13 from monies deposited with the Trustee pursuant thereto prior to commencement of proceedings for such
dissolution, winding up, liquidation or reorganization), and upon any such dissolution or winding up or liquidation or reorganization of the Company or bankruptcy, insolvency, receivership or other similar proceeding, any payment by the Company, or
distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the holders of the Notes or the Trustee would be entitled, except for the provisions of this Article 4 shall (except as aforesaid) be
paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the holders of the Notes or by the Trustee under this Indenture if received by them or it, directly
to the holders of Senior Indebtedness (pro rata to such holders on the basis of the respective amounts of Senior Indebtedness held by such holders, or as otherwise required by law or a court order) or their Representative or Representatives, as
their respective interests may appear, to the extent necessary to pay all Senior Indebtedness in full, in cash or other payment satisfactory to the holders of such Senior Indebtedness, after giving effect to any concurrent payment or distribution to
or for the holders of Senior Indebtedness, before any payment or distribution is made to the holders of the Notes or to the Trustee. 
  
 For purposes of this Article 4 the words, “cash, property or securities” shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this Article 4 with respect to the
Notes to the payment of all Senior Indebtedness which may at the time be outstanding 
  

 29 

 provided that (i) the Senior Indebtedness is assumed by the new corporation, if any, resulting from any
reorganization or readjustment, and (ii) the rights of the holders of Senior Indebtedness (other than leases which are not assumed by the Company or the new corporation, as the case may be) are not, without the consent of such holders, altered by
such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance or transfer of its property as an entirety,
or substantially as an entirety, to another Person upon the terms and conditions provided for in Article 12 shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section 4.02 if such other Person
shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions stated in Article 12. 
  
 In the event of the acceleration of the Notes because of an Event of Default, no payment or distribution shall be made to the Trustee or any holder of
Notes in respect of the principal of, premium, if any, or interest (including Liquidated Damages, if any) on the Notes (including, but not limited to, the purchase price with respect to the Notes submitted for purchase in accordance with Section
3.02 hereof, as provided in this Indenture), except payments and distributions made by the Trustee as permitted by Section 4.05 hereof, until all Senior Indebtedness has been paid in full in cash or other payment satisfactory to the holders of
Senior Indebtedness or such acceleration is rescinded in accordance with the terms of this Indenture. If payment of the Notes is accelerated because of an Event of Default, the Company or the Trustee shall promptly notify holders of Senior
Indebtedness of the acceleration. 
  
 In the event that,
notwithstanding the foregoing provisions, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities (including, without limitation, by way of setoff or otherwise), prohibited by the
foregoing provisions in this Section 4.02, 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, or provision is
made for such payment thereof in accordance with its terms 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, as their respective interests may appear, as calculated by the Company, for application to the payment of any 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 to or for the holders of such Senior Indebtedness.

  

 30 

 Nothing in this Section 4.02 shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 8.06 hereof. This Section 4.02 shall be subject to the further provisions of Section 4.05 hereof. 
  
 Section 4.03 Subrogation of Notes. Subject to the payment in full of all Senior Indebtedness, the rights of the holders of the Notes shall be
subrogated to the extent of the payments or distributions made to the holders of such Senior Indebtedness pursuant to the provisions of this Article 4 (equally and ratably with the holders of all indebtedness of the Company which by its express
terms is subordinated to other indebtedness of the Company to substantially the same extent as the Notes are subordinated and is entitled to like rights of subrogation) to the rights of the holders of Senior Indebtedness to receive payments or
distributions of cash, property or securities of the Company applicable to the Senior Indebtedness until the principal, premium, if any, and interest (including Liquidated Damages, if any) on the Notes shall be paid in full, and, for the purposes of
such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any cash, property or securities to which the holders of the Notes or the Trustee would be entitled except for the provisions of this Article 4 and no
payment pursuant to the provisions of this Article 4 to or for the benefit of 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 by the Company to or on account of the Senior Indebtedness, and no payments or distributions of cash, property or securities to or for the benefit of the holders of the Notes pursuant to the
subrogation provisions of this Article 4 which would otherwise have been paid to the holders of Senior Indebtedness, shall be deemed to be a payment by the Company to or for the account of the Notes. It is understood that the provisions of this
Article 4 are intended solely for the purposes of defining the relative rights of the holders of the Notes, on the one hand, and the holders of the Senior Indebtedness, on the other hand. 
  
 Nothing contained in this Article 4 or elsewhere in this Indenture or in the Notes is intended to or shall impair, as among
the Company, its creditors other than the holders of Senior Indebtedness, and the holders of the Notes, the obligation of the Company, which is absolute and unconditional, to pay to the holders of the Notes the principal of, premium, if any, and
interest (including Liquidated Damages, if any) on the Notes as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the holders of the Notes and creditors of the
Company other than the holders of the Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or the holder of any Note from exercising all remedies otherwise permitted by applicable law upon default under this Indenture,
subject to the rights, if any, under this Article 4 of the holders of Senior Indebtedness in respect of cash, property or securities of the Company received upon the exercise of any such remedy. 
  

 31 

 Upon any payment or distribution of assets of the Company referred to in this Article 4, the Trustee,
subject to the provisions of Section 8.01 hereof, and the holders of the Notes shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which such bankruptcy, dissolution, winding up, liquidation or
reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, delivered to the Trustee or to the holders of the Notes, for the purpose
of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon and all other facts pertinent thereto or to this Article 4.

  
 Section 4.04 Authorization To Effect Subordination.
Each holder of a Note by the holder’s acceptance thereof authorizes and directs the Trustee on the holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article 4 and
appoints the Trustee to act as the holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in the third paragraph of
Section 7.02 hereof at least 30 days before the expiration of the time to file such claim, the holders of any Senior Indebtedness or their Representatives are hereby authorized to file an appropriate claim for and on behalf of the holders of the
Notes. 
  
 Section 4.05 Notice to Trustee. The Company
shall give prompt written notice in the form of an Officers’ Certificate to a Responsible Officer of the Trustee and to any paying agent of any fact known to the Company that would prohibit the making of any payment of monies to or by the
Trustee or any paying agent in respect of the Notes pursuant to the provisions of this Article 4. Notwithstanding the provisions of this Article 4 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the
existence of any facts that would prohibit the making of any payment of monies to or by the Trustee in respect of the Notes pursuant to the provisions of this Article 4 unless and until a Responsible Officer of the Trustee shall have received
written notice thereof at the Corporate Trust Office from the Company (in the form of an Officers’ Certificate) or a Representative or a holder or holders of Senior Indebtedness, and before the receipt of any such written notice, the Trustee,
subject to the provisions of Section 8.01 hereof, shall be entitled in all respects to assume that no such facts exist; provided, however, that if on a date not less than one Business Day prior to the date upon which by the terms
hereof any such monies may become payable for any purpose (including, without limitation, the payment of the principal of, or premium, if any, or interest (including Liquidated 
  

 32 

 Damages, if any) on any Note) the Trustee shall not have received, with respect to such monies, the notice provided for
in this Section 4.05 then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to apply monies received to the purpose for which they were received, and shall not be affected by any notice to
the contrary that may be received by it on or after such prior date. 
  
 Notwithstanding anything in this Article 4 to the contrary, nothing shall prevent any payment by the Trustee to the Noteholders of monies deposited with it pursuant to Section 13.01 hereof, and any such payment shall not be subject to the
provisions of this Article 4. 
  
 The Trustee, subject to the
provisions of Section 8.01 hereof, shall be entitled to rely on the delivery to it of a written notice by a Representative or a person representing himself to be a holder of Senior Indebtedness (or a trustee on behalf of such holder) to establish
that such notice has been given by a Representative or a holder of Senior Indebtedness or a trustee on behalf of any such holder or holders. The Trustee shall not be required to make any payment or distribution to or on behalf of a holder of Senior
Indebtedness pursuant to this Article 4 unless it has received satisfactory evidence 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 4. 
  
 Section 4.06 Trustee’s Relation To Senior Indebtedness. The Trustee, in its individual capacity, shall be entitled to all the rights set forth in this Article 4 in respect of any Senior Indebtedness at any
time held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in Section 8.13 hereof or elsewhere in this Indenture shall deprive the Trustee of any of its rights as such holder. 
  
 With respect to the holders of Senior Indebtedness, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are specifically set forth in this Article 4 and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this Indenture against the
Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and, subject to the provisions of Section 8.01 hereof, the Trustee shall not be liable to any holder of Senior Indebtedness (i) for any failure
to make any payments or distributions to such holder or (ii) if it shall pay over or deliver to holders of Notes, the Company or any other Person money in compliance with this Article 4. 
  
 Section 4.07 No Impairment of Subordination. No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or 
  

 33 

 failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof which any such holder may have or otherwise be charged with. Senior Indebtedness may be created, renewed or extended and
holders of Senior Indebtedness may exercise any rights under any instrument creating or evidencing such Senior Indebtedness, including, without limitation, any waiver of default thereunder, without any notice to or consent from the holders of the
Notes or the Trustee. No compromise, alteration, amendment, modification, extension, renewal or other change of, or waiver, consent or other action in respect of, any liability or obligation under or in respect of the Senior Indebtedness or any
terms or conditions of any instrument creating or evidencing such Senior Indebtedness shall in any way alter or affect any of the provisions of this Article 4 or the subordination of the Notes provided thereby. 
  
 Section 4.08 Certain Conversions Not Deemed Payment. For the purposes
of this Article 4 only, (1) the issuance and delivery of Junior Securities upon conversion of Notes in accordance with Article 15 shall not be deemed to constitute a payment or distribution on account of the principal of, premium, if any, or
interest (including Liquidated Damages, if any) on Notes or on account of the purchase or other acquisition of Notes, and (2) the payment, issuance or delivery of cash (except in satisfaction of fractional shares pursuant to Section 15.04 hereof),
property or securities (other than Junior Securities) upon conversion of a Note shall be deemed to constitute payment on account of the principal of, premium, if any, or interest (including Liquidated Damages, if any) on such Note. For the purposes
of this Section 4.08 the term “Junior Securities” means (a) shares of any stock of any class of the Company or (b) securities of the Company that are subordinated in right of payment to all Senior Indebtedness that may be
outstanding at the time of issuance or delivery of such securities to substantially the same extent as, or to a greater extent than, the Notes are so subordinated as provided in this Article 4. Nothing contained in this Article 4 or elsewhere in
this Indenture or in the Notes is intended to or shall impair, as among the Company, its creditors (other than holders of Senior Indebtedness) and the Noteholders, the right, which is absolute and unconditional, of the holder of any Note to convert
such Note in accordance with Article 4. 
  
 Section 4.09
Article Applicable to Paying Agents. If at any time any paying agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article 4 shall (unless the
context otherwise requires) be construed as extending to and including such paying agent within its meaning as fully for all intents and purposes as if such paying agent were named in this Article 4 in addition to or in place of the Trustee;
provided, however, that the first paragraph of Section 4.05 hereof shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as paying agent. 
  

 34 

 The Trustee shall not be responsible for the actions or inactions of any other paying agents (including
the Company if acting as its own paying agent) and shall have no control of any funds held by such other paying agents. 
  
 Section 4.10 Senior Indebtedness Entitled to Rely. The holders of Senior Indebtedness shall have the right to rely upon this Article 4 and no
amendment or modification of the provisions contained herein shall diminish the rights of such holders unless such holders shall have agreed in writing thereto. 
  

Section 4.11 Reliance on Judicial Order or Certificate of Liquidating Agent. Upon any payment or distribution of assets of the Company referred
to in this Article 4 the Trustee and the Noteholders shall be entitled to 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 of the trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered
to the Trustee or to the Noteholders, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of 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 4.

 The Company hereby initially designates the Trustee as paying
agent, Note registrar, Custodian and conversion agent and each of the Corporate Trust Office and the office or agency of the Trustee in The Borough of Manhattan at 4 New York Plaza, 1st Floor, New York, New York 10004-2413, shall be considered as

other than the Trustee, or if the Trustee shall appoint such a paying agent, the Company will cause such paying agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of
this Section 5.04: 
  
 (i) that it will hold all
sums held by it as such agent for the payment of the principal of and premium, if any, or interest (including Liquidated Damages, if any) on the Notes (whether such sums have been paid to it by the Company or by any other obligor on the Notes) in

principal, premium, if any, or interest and Liquidated Damages, if any, and (unless such paying agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided, however, that if such
deposit is made on the due date, such deposit shall be received by the paying agent by 10:00 a.m. New York City time, on such date. 
  
 (b) If the Company shall act as its own paying agent, it will, on or before each due date of the principal of, premium, if any, or interest (including

 (c) Anything in this Section 5.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee
all sums held in trust by the Company or any paying agent hereunder as required by this Section 5.04 such sums to be held by the Trustee upon the trusts herein contained and upon such payment by the Company or any paying agent to the Trustee, the

necessary to preserve and keep in full force and effect its existence and rights (charter and statutory); provided, however, that the Company shall not be required to preserve any such right if the Company shall determine that the
preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Noteholders. 
  
 Section 5.06 Maintenance of Properties. The Company will cause all properties used or useful in the conduct of its
business or the business of any Significant Subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements,

nothing in this Section shall prevent the Company from discontinuing the operation or maintenance of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business or the business of any
subsidiary and not disadvantageous in any material respect to the Noteholders. 
  
 Section 5.07 Payment of Taxes and Other Claims. The Company will pay or discharge, or cause to be paid or discharged, before the same may become delinquent, (i) all taxes, assessments and governmental charges
levied or imposed upon the Company or any Significant Subsidiary or upon the income, profits or property of the Company or any Significant Subsidiary, (ii) all claims for labor, materials and supplies which, if unpaid, might by law become a lien or

exchange or conversion of any Notes or with respect to this Indenture; provided, however, that, in the case of clauses (i) and (ii) above, the Company shall not be required to pay or discharge or cause to be paid or discharged any such

the period prior to the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), the Company covenants and agrees that it shall, during any period in which it is not
subject to Section 13 or 15(d) under the Exchange Act, make available to any holder or beneficial holder of Notes or any Common Stock issued upon conversion thereof 
  

 38 

 which continue to be Restricted Securities in connection with any sale thereof and any prospective purchaser of Notes or
such Common Stock designated by such holder or beneficial holder, the information required pursuant to Rule 144A(d)(4) under the Securities Act upon the request of any holder or beneficial holder of the Notes or such Common Stock and it will take
such further action as any holder or beneficial holder of such Notes or such Common Stock may reasonably request, all to the extent required from time to time to enable such holder or beneficial holder to sell its Notes or Common Stock without
registration under the Securities Act within the limitation of the exemption provided by Rule 144A, as such Rule may be amended from time to time. Upon the request of any holder or any beneficial holder of the Notes or such Common Stock, the Company
will deliver to such holder or beneficial holder a written statement as to whether it has complied with such requirements. 
  
 Section 5.09 Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist
upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal of, premium, if any, or
interest (including Liquidated Damages, if any) on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture and the Company (to the extent it
may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law had been enacted. 
  
 Section 5.10 Compliance Certificate. The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company, a certificate signed by either the principal executive officer,
principal financial officer or principal accounting officer of the Company, stating whether or not to the best knowledge of the signer thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions
of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and the nature and the status thereof of which the signer may have knowledge.

  
 The Company will deliver to the Trustee, forthwith upon
becoming aware of (i) any default in the performance or observance of any covenant, agreement or condition contained in this Indenture, or (ii) any Event of Default, an Officers’ Certificate specifying with particularity such default or Event
of Default and further stating what action the Company has taken, is taking or proposes to take with respect thereto. 
  

 39 

 Any notice required to be given under this Section 5.10 or Section 4.05 hereof shall be delivered to a
Responsible Officer of the Trustee at its Corporate Trust Office. In the event that the payment of the Notes is accelerated because of an Event of Default, the Company shall promptly provide written notice to the Trustee specifying the names and
addresses of the holders of Senior Indebtedness or a Representative of such Senior Indebtedness if the Trustee (and not the Company) is to provide holders of Senior Indebtedness or such Representative notice of such acceleration under Section 4.05
hereof. 
  
 Section 5.11 Liquidated Damages Notice. In the
event that the Company is required to pay Liquidated Damages to holders of Notes pursuant to the Registration Rights Agreement, the Company will provide written notice (“Liquidated Damages Notice”) to the Trustee of its obligation
to pay Liquidated Damages no later than 15 days prior to the proposed payment date for the Liquidated Damages, and the Liquidated Damages Notice shall set forth the amount of Liquidated Damages to be paid by the Company on such payment date. The
Trustee shall not at any time be under any duty or responsibility to any holder of Notes to determine the Liquidated Damages, or with respect to the nature, extent or calculation of the amount of Liquidated Damages when made, or with respect to the
method employed in such calculation of the Liquidated Damages.

not more than 15 days (or such other date as the Trustee may reasonably request in order to so provide any such notices) prior to the time such information is furnished, except that no such list need be furnished by the Company to the Trustee so
long as the Trustee is acting as the sole Note registrar. 
  
 Section 6.02 Preservation And Disclosure Of Lists. (a) The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the holders of Notes contained in
the most recent 
  

 40 

 list furnished to it as provided in Section 6.01 hereof or maintained by the Trustee in its capacity as Note registrar or
co-registrar in respect of the Notes, if so acting. The Trustee may destroy any list furnished to it as provided in Section 6.01 hereof upon receipt of a new list so furnished. 
  
 (b) The rights of Noteholders to communicate with other holders of Notes with respect to their rights under this Indenture
or under the Notes, and the corresponding rights and duties of the Trustee, shall be as provided by the Trust Indenture Act or this Indenture. 
  
 (c) Every Noteholder, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor the Trustee nor any agent of

provided, however, that any such information, documents or reports required to be filed with the Commission pursuant to Section 13 or 15(d) of the Exchange Act shall be filed with the Trustee within 15 days after the same is so
required to be filed with the Commission. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

 ARTICLE 7 
 REMEDIES OF THE TRUSTEE AND NOTEHOLDERS ON AN EVENT OF
DEFAULT 
  
 Section 7.01 Events of Default.
In case one or more of the following Events of Default (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court
or any order, rule or regulation of any administrative or governmental body) shall have occurred and be continuing: 
  
 (a) default in the payment of any installment of interest (including Liquidated Damages, if any) upon any of the Notes as and when the same shall become
due and payable, and continuance of such default for a period of 30 days, whether or not such payment is permitted under Article 4 hereof; or 
  
 (b) default in the payment of the principal of or premium, if any, on any of the Notes as and when the same shall become due and payable either at
maturity or in connection with any purchase pursuant to Article 3, by acceleration or otherwise, whether or not such payment is permitted under Article 4 hereof; or 
  
 (c) failure on the part of the Company duly to observe or perform any other of the covenants or agreements on the part of
the Company in the Notes or in this Indenture (other than a covenant or agreement a default in whose performance or whose breach is elsewhere in this Section 7.01 specifically dealt with) continued for a period of 60 days after the date on which
written notice 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 25% in aggregate principal amount of
the Notes at the time outstanding determined in accordance with Section 9.04 hereof; or 
  
 (d) the Company shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to the Company or its debts under any bankruptcy, insolvency or other similar law
now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or any substantial part of the property of the Company, or shall consent to any such relief or to the
appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against the Company, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they
become due; or 
  
 (e) an involuntary case or other proceeding
shall be commenced against the Company seeking liquidation, reorganization or other relief with respect to the Company or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a
trustee, receiver, liquidator, custodian or other similar official of the Company or any substantial part of the property of the Company, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 90
consecutive days; 
  

 42 

 then, and in each and every such case (other than an Event of Default specified in Section 7.01(d) or 7.01(e) hereof),
unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the holders of not less than 25% in aggregate principal amount of the Notes then outstanding hereunder determined in accordance with Section
9.04 hereof by notice in writing to the Company (and to the Trustee if given by Noteholders), may declare the principal of and premium, if any, on all the Notes and the interest accrued thereon (including Liquidated Damages, if any) to be due and
payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Notes contained to the contrary notwithstanding. If an Event of Default specified in Section
7.01(d) or 7.01(e) hereof occurs, the principal of all the Notes and the interest accrued thereon (including Liquidated Damages, if any) shall be immediately and automatically due and payable without necessity of further action. This provision,
however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as
hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all matured installments of interest (including Liquidated Damages, if any) upon all Notes and the principal of and premium, if any, on any and all
Notes which shall have become due otherwise than by acceleration (with interest on overdue installments of interest (including Liquidated Damages, if any) (to the extent that payment of such interest is enforceable under applicable law) and on such
principal and premium, if any, at the rate of 0.5% per annum from the due date to the date of such payment or deposit) and amounts due to the Trustee pursuant to Section 8.06 hereof, and if any and all defaults under this Indenture, other than the
nonpayment of principal of and premium, if any, and accrued interest on (including Liquidated Damages, if any) Notes which shall have become due by acceleration, shall have been cured or waived pursuant to Section 7.07 hereof, then and in every such
case the holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all defaults or Events of Default and rescind and annul such declaration and its consequences;
but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default or Event of Default, or shall impair any right consequent thereon. The Company shall notify in writing a Responsible Officer of the Trustee,
promptly upon becoming aware thereof, of any Event of Default. 
  
 In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of such waiver or rescission and annulment or for any other reason or 
  

 43 

 shall have been determined adversely to the Trustee, then and in every such case the Company, the holders of Notes, and
the Trustee shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the holders of Notes, and the Trustee shall continue as though no such proceeding had been taken (subject
to any determination to the contrary). 
  
 Section 7.02
Payments of Notes on Default; Suit Therefor. Subject to Section 7.01 hereof, the Company covenants that (a) in case default shall be made in the payment of any installment of interest (including Liquidated Damages, if any) upon any of the
Notes as and when the same shall become due and payable, and such default shall have continued for a period of 30 days, or (b) in case default shall be made in the payment of the principal of or premium, if any, on any of the Notes as and when the
same shall have become due and payable, whether at maturity of the Notes or in connection with any redemption, by or under this Indenture or otherwise, then, upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the
holders of the Notes, the whole amount that then shall have become due and payable on all such Notes for principal and premium, if any, or interest (including Liquidated Damages, if any), as the case may be, with interest upon the overdue principal
and premium, if any, and (to the extent that payment of such interest is enforceable under applicable law) upon the overdue installments of interest (including Liquidated Damages, if any) at the rate of 0.5% per annum from the date due until the
date payment is made, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other amounts due
the Trustee under Section 8.06 hereof. Until such demand by the Trustee, the Company may pay the principal of and premium, if any, and interest on (including Liquidated Damages, if any) the Notes to the registered holders, whether or not the Notes
are overdue. 
  
 In case the Company shall fail forthwith to pay
such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Company or any other obligor on the Notes and collect in the manner provided by law out of the property of the Company
or any other obligor on the Notes wherever situated the monies adjudged or decreed to be payable. 
  
 In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of
the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar 
  

 44 

 official shall have been appointed for or taken possession of the Company or such other obligor, the property of the
Company or such other obligor, or in the case of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether
the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 7.02 shall be entitled and
empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal, premium, if any, and interest (including Liquidated Damages, if any) owing and unpaid in respect of the Notes, and,
in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and of the Noteholders allowed in such judicial proceedings relative to the
Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any
amounts due the Trustee under Section 8.06 hereof, and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Noteholders to make such payments to the Trustee,
and, in the event that the Trustee shall consent to the making of such payments directly to the Noteholders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including counsel fees incurred
by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be
secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property which the holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of
reorganization or arrangement or otherwise. 
  
 All rights of
action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit
or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, be for the ratable benefit of the holders of the Notes. 
  
 In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the
holders of the Notes, and it shall not be necessary to make any holders of the Notes parties to any such proceedings. 
  

 45 

 Section 7.03 Application of Monies Collected by Trustee. Any monies collected by the Trustee
pursuant to this Article 7 shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and
upon surrender thereof, if fully paid: 
  
 FIRST:
To the payment of all amounts due the Trustee under Section 8.06 hereof; 
  
 SECOND: Subject to the provisions of Article 4, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest (including Liquidated Damages, if any) on the Notes in
default in the order of the maturity of the installments of such interest, with interest (including Liquidated Damages, if any) (to the extent that such interest has been collected by the Trustee) upon the overdue installments of interest (including
Liquidated Damages, if any) at the rate of 0.5% per annum, such payments to be made ratably to the Persons entitled thereto; 
  
 THIRD: Subject to the provisions of Article 4, in case the principal of the outstanding Notes shall have become due, by declaration or
otherwise, and be unpaid, to the payment of the whole amount then owing and unpaid upon the Notes for principal and premium, if any, and interest (including Liquidated Damages, if any), with interest on the overdue principal and premium, if any, and
(to the extent that such interest has been collected by the Trustee) upon overdue installments of interest (including Liquidated Damages, if any) at the rate of 0.5% per annum, and in case such monies shall be insufficient to pay in full the whole
amounts so due and unpaid upon the Notes, then to the payment of such principal and premium, if any, and interest (including Liquidated Damages, if any) without preference or priority of principal and premium, if any, over interest (including
Liquidated Damages, if any), or of interest (including Liquidated Damages, if any) over principal and premium, if any, or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the
aggregate of such principal and premium, if any, and accrued and unpaid interest; and 
  
 FOURTH: Subject to the provisions of Article 4, to the payment of the remainder, if any, to the Company or any other Person lawfully
entitled thereto. 
  

 46 

 Section 7.04 Proceedings By Noteholder. No holder of any Note shall have any right by virtue of or
by reference to any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar
official, or for any other remedy hereunder, unless such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, and unless also the holders of not less than
25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for 60 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any
such action, suit or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 7.07 hereof; it being understood and intended, and being expressly covenanted by the taker and holder of
every Note with every other taker and holder and the Trustee, that no one or more holders of Notes shall have any right in any manner whatever by virtue of or by reference to any provision of this Indenture to affect, disturb or prejudice the rights
of any other holder of Notes, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of
all holders of Notes (except as otherwise provided herein). For the protection and enforcement of this Section 7.04, each and every Noteholder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 

 
 Notwithstanding any other provision of this Indenture and any provision of
any Note, the right of any holder of any Note to receive payment of the principal of and premium, if any (including the purchase price upon purchase pursuant to Article 3), and accrued interest on (including Liquidated Damages, if any) such Note, on
or after the respective due dates expressed in such Note or in the event of purchase, or to institute suit for the enforcement of any such payment on or after such respective dates against the Company shall not be impaired or affected without the
consent of such holder. 
  
 Anything in this Indenture or the
Notes to the contrary notwithstanding, the holder of any Note, without the consent of either the Trustee or the holder of any other Note, in its own behalf and for its own benefit, may enforce, and may institute and maintain any proceeding suitable
to enforce, its rights of conversion as provided herein. 
  
 Section 7.05 Proceedings By Trustee. In case of an Event of Default, the Trustee may, in its discretion, proceed to protect and enforce the rights vested 
  

 47 

 in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such
rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this
Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 
  
 Section 7.06 Remedies Cumulative And Continuing. Except as provided in Section 2.06 hereof, all powers and remedies given by this Article 7 to the
Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the holders of the Notes, by judicial proceedings or
otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any holder of any of the Notes to exercise any right or power accruing upon any default or
Event of Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or any acquiescence therein, and, subject to the provisions of Section 7.04 hereof, every power and
remedy given by this Article 7 or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders. 
  
 Section 7.07 Direction of Proceedings and Waiver of Defaults By Majority
of Noteholders. The holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 9.04 hereof shall have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee; provided, however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, (b) the Trustee may
take any other action which is not inconsistent with such direction and (c) the Trustee may decline to take any action that would benefit some Noteholder to the detriment of other Noteholders. The holders of a majority in aggregate principal amount
of the Notes at the time outstanding determined in accordance with Section 9.04 hereof may, on behalf of the holders of all of the Notes, waive any past default or Event of Default hereunder and its consequences except (i) subject to Section 7.01
hereof, a default in the payment of interest (including Liquidated Damages, if any) or premium, if any, on, or the principal of, any Note, which may not be waived without the consent of the holder of such Note, (ii) a failure by the Company to
convert any Note into Common Stock, which may not be waived without the consent of the holder of such Note, (iii) a default in the payment of the purchase price pursuant to Article 3, which may not be waived without the consent of the holder of such
Note, and (iv) a default in respect of a covenant or provisions hereof that under Article 11 cannot be modified or amended without the consent of the holders of each or all Notes then outstanding or affected 
  

 48 

 thereby. Upon any such waiver, the Company, the Trustee and the holders of the Notes shall be restored to their former
positions and rights hereunder; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. Whenever any default or Event of Default hereunder shall have been waived as permitted by
this Section 7.07 said default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other default or Event of Default
or impair any right consequent thereon. 
  
 Section 7.08 Notice
of Defaults. The Trustee shall, within 90 days after a Responsible Officer of the Trustee has knowledge of the occurrence of a default, mail to all Noteholders, as the names and addresses of such holders appear upon the Note register, notice of
all defaults known to a Responsible Officer, unless such defaults shall have been cured or waived before the giving of such notice; provided, however, that except in the case of default in the payment of the principal of, or premium,
if any, or interest (including Liquidated Damages, if any) on any of the Notes, the Trustee shall be protected in withholding such notice if and so long as a trust committee of directors and/or Responsible Officers of the Trustee in good faith
determines that the withholding of such notice is in the interests of the Noteholders. 
  
 Section 7.09 Undertaking to Pay Costs. All parties to this Indenture agree, and each holder of any Note by his acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require,
in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of
such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses
made by such party litigant; provided, however, that the provisions of this Section 7.09 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Noteholder, or group of
Noteholders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 9.04 hereof, or to any suit instituted by any Noteholder for the enforcement of the payment of the
principal of or premium, if any, or interest (including Liquidated Damages, if any) on any Note on or after the due date expressed in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of
Article 15.

 ARTICLE 8 
 THE TRUSTEE 
  
 Section 8.01 Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default which may have occurred, undertakes to perform such
duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. 
  
 No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or
its own willful misconduct, except that: 
  
 (a) prior to the
occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have occurred: 
  
 (i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture and the Trust
Indenture Act, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture or the Trust
Indenture Act against the Trustee; and 
  
 (ii)
in the absence of bad faith and willful misconduct on the part of the Trustee, the Trustee may conclusively rely as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to
the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to
examine the same to determine whether or not they conform to the requirements of this Indenture; 
  
 (b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless the Trustee
was negligent in ascertaining the pertinent facts; 
  
 (c) the
Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the written direction of the holders of not less than a majority in principal amount of the Notes at the time outstanding
determined as provided in Section 9.04 hereof relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture; 

 

 50 

 (d) whether or not therein provided, every provision of this Indenture relating to the conduct or
affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section; 
  
 (e) the Trustee shall not be liable in respect of any payment (as to the correctness of amount, entitlement to receive or any other matters relating to
payment) or notice effected by the Company or any paying agent or any records maintained by any co-registrar with respect to the Notes; 
  
 (f) if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice to be sent to the Trustee,
the Trustee may conclusively rely on its failure to receive such notice as reason to act as if no such event occurred; and 
  
 (g) the Trustee shall not be deemed to have knowledge of any Event of Default hereunder unless it shall have been notified in writing of such Event of
Default by the Company or the holders of at least 10% in aggregate principal amount of the Notes. 
  
 None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably
assured to it. 
  
 Section 8.02 Reliance on Documents,
Opinions, Etc. Except as otherwise provided in Section 8.01 hereof: 
  
 (a) the Trustee may rely and shall be protected in acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, note, coupon or other paper or
document (whether in its original or facsimile form) believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties; 
  
 (b) any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an
Officers’ Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant
Secretary of the Company; 
  

 51 

 (c) the Trustee may consult with counsel of its own selection and any advice or Opinion of Counsel shall
be full and complete authorization and protection in respect of any action taken or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 
  
 (d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the
request, order or direction of any of the Noteholders pursuant to the provisions of this Indenture, unless such Noteholders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be
incurred therein or thereby; 
  
 (e) the Trustee shall not be
bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its
discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and
premises of the Company, personally or by agent or attorney; and 
  
 (f) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of
any agent or attorney appointed by it with due care hereunder. 
  
 Section 8.03 No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any Notes or
the proceeds of any Notes authenticated and delivered by the Trustee in conformity with the provisions of this Indenture. 
  
 Section 8.04 Trustee, Paying Agents, Conversion Agents or Registrar May Own Notes. The Trustee, any paying agent, any conversion agent or Note
registrar, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not Trustee, paying agent, conversion agent or Note registrar. 
  
 Section 8.05 Monies to Be Held in Trust. Subject to the provisions of
Sections 4.02 and 13.04 hereof, all monies received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be 

 

 52 

 segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on
any money received by it hereunder except as may be agreed in writing from time to time by the Company and the Trustee. 
  
 Section 8.06 Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall
be entitled to, reasonable compensation for all services rendered by it hereunder in any capacity (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as mutually agreed to from time to
time in writing between the Company and the Trustee, and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the
provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence,
willful misconduct, recklessness or bad faith. The Company also covenants to indemnify the Trustee (or any officer, director or employee of the Trustee), acting in any capacity under this Indenture and its agents and any authenticating agent for,
and to hold them harmless against, any and all loss, liability, claim or expense incurred without negligence, willful misconduct, recklessness or bad faith on the part of the Trustee or such officers, directors, employees and agent or authenticating
agent, as the case may be, and arising out of or in connection with the acceptance or administration of this trust or in any other capacity hereunder, including the costs and expenses of defending themselves against any claim of liability in the
premises. The obligations of the Company under this Section 8.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall be secured by a lien prior to that of the Notes upon all
property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the holders of particular Notes. The obligation of the Company under this Section shall survive the satisfaction and discharge of this
Indenture. 
  
 When the Trustee and its agents and any
authenticating agent incur expenses or render services after an Event of Default specified in Section 7.01(d) or 7.01(e) hereof with respect to the Company occurs, the expenses and the compensation for the services are intended to constitute
expenses of administration under any bankruptcy, insolvency or similar laws. 
  
 Section 8.07 Officers’ Certificate as Evidence. Except as otherwise provided in Section 8.01 hereof, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary
or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) 
  

 53 

 may, in the absence of bad faith or willful misconduct on the part of the Trustee, be deemed to be conclusively proved
and established by an Officers’ Certificate delivered to the Trustee. 
  
 Section 8.08 Conflicting Interests of Trustee. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest
or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. 
  
 Section 8.09 Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the Trust
Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000 (or if such Person is a member of a bank holding company system, its bank holding company shall have a combined capital and surplus of at least $50,000,000).
If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section the combined capital and surplus of such Person shall be deemed
to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 8.09, it shall resign immediately in the
manner and with the effect hereinafter specified in this Article 8. 
  
 Section 8.10 Resignation or Removal of Trustee. 
  
 (a) The Trustee may at any time resign by giving written notice of such resignation to the Company and to the holders of Notes. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee by written
instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. If no successor trustee shall have been so appointed and have
accepted appointment 60 days after the mailing of such notice of resignation to the Noteholders, the resigning Trustee may, upon 10 business days’ notice to the Company and the Noteholders, appoint a successor identified in such notice or may
petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor trustee, or, if any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, subject to the provisions
of Section 7.09 hereof, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a
successor trustee. 
  

 54 

 (b) In case at any time any of the following shall occur: 
  
 (i) the Trustee shall fail to comply with Section 8.08
hereof after written request therefor by the Company or by any Noteholder who has been a bona fide holder of a Note or Notes for at least six months; or 
  
 (ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 8.09 hereof and shall fail to resign after
written request therefor by the Company or by any such Noteholder; or 
  
 (iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control
of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation; 
  
 then, in any such case, the Company may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be
delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 7.09 hereof, any Noteholder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee; provided, however, that if no successor Trustee shall have been appointed and have
accepted appointment 60 days after either the Company or the Noteholders has removed the Trustee, the Trustee so removed may petition, at the expense of the Company, any court of competent jurisdiction for an appointment of a successor trustee. Such
court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 
  
 (c) The holders of a majority in aggregate principal amount of the Notes at the time outstanding may at any time remove the Trustee and nominate a
successor trustee which shall be deemed appointed as successor trustee unless, within 10 days after notice to the Company of such nomination, the Company objects thereto, in which case the Trustee so removed or any Noteholder, or if such Trustee so
removed or any Noteholder fails to act, the Company, upon the terms and conditions and otherwise as in Section 8.10(a) hereof provided, may petition any court of competent jurisdiction for an appointment of a successor trustee. 
  
 (d) Any resignation or removal of the Trustee and appointment of a successor
trustee pursuant to any of the provisions of this Section 8.10 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 8.11 hereof. 
  

 55 

 Section 8.11 Acceptance by Successor Trustee. Any successor trustee appointed as provided in
Section 8.10 hereof shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective
and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein; but,
nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amount then due it pursuant to the provisions of Section 8.06 hereof, execute and deliver an instrument
transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and
confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a lien upon all property and funds held or collected by such trustee as such, except for funds held in trust for the benefit of
holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 8.06 hereof. 
  
 No successor trustee shall accept appointment as provided in this Section 8.11 hereof unless, at the time of such acceptance, such successor trustee shall
be qualified under the provisions of Section 8.08 hereof and be eligible under the provisions of Section 8.09 hereof. 
  
 Upon acceptance of appointment by a successor trustee as provided in this Section 8.11 hereof, the Company (or the former trustee, at the written
direction of the Company) shall mail or cause to be mailed notice of the succession of such trustee hereunder to the holders of Notes at their addresses as they shall appear on the Note register. If the Company fails to mail such notice within 10
days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. 
  
 Section 8.12 Succession by Merger, Etc. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or
any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee (including any trust created by
this Indenture), shall be the successor to the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that in the case of any corporation succeeding to all or
substantially all of the corporate trust business of the Trustee, such corporation shall be qualified under the provisions of Section 8.08 hereof and eligible under the provisions of Section 8.09 hereof. 
  

 56 

 In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture,
any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver
such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or any authenticating agent appointed by such successor trustee may authenticate such Notes in the name of the
successor trustee; and in all such cases such certificates shall have the full force that is provided in the Notes or in this Indenture; provided, however, that the right to adopt the certificate of authentication of any predecessor
Trustee or authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation. 
  
 Section 8.13 Preferential Collection of Claims. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the
Notes), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of the claims against the Company (or any such other obligor). 
  
 Section 8.14 Trustee’s Application for Instructions from the Company. Any application by the Trustee for written
instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the holders of the Notes or holders of Senior Indebtedness under this Indenture, including,
without limitation, under Article 4 hereof) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such
omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be
less than three Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in
the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted. 
  
 ARTICLE 9 
 THE
NOTEHOLDERS 
  
 Section 9.01 Action by
Noteholders. Whenever in this Indenture it is provided that the holders of a specified percentage in aggregate principal amount of the Notes may take any action (including the making of any demand or request, 
  

 57 

 the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any
such action, the holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in writing, or (b) by the
record of the holders of Notes voting in favor thereof at any meeting of Noteholders duly called and held in accordance with the provisions of Article 10, or (c) by a combination of such instrument or instruments and any such record of such a
meeting of Noteholders. Whenever the Company or the Trustee solicits the taking of any action by the holders of the Notes, the Company or the Trustee may fix in advance of such solicitation, a date as the record date for determining holders entitled
to take such action. The record date shall be not more than 15 days prior to the date of commencement of solicitation of such action. 
  
 Section 9.02 Proof of Execution by Noteholders. Subject to the provisions of Sections 8.01, 8.02 and 10.05 hereof, proof of the execution of any
instrument by a Noteholder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes
shall be proved by the registry of such Notes or by a certificate of the Note registrar. 
  
 The record of any Noteholders’ meeting shall be proved in the manner provided in Section 10.06 hereof. 
  
 Section 9.03 Who Are Deemed Absolute Owners. The Company, the Trustee, any paying agent, any conversion agent and any Note registrar may deem the
Person in whose name such Note shall be registered upon the Note register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon
made by any Person other than the Company or any Note registrar) for the purpose of receiving payment of or on account of the principal of, premium, if any, and interest on such Note, for conversion of such Note and for all other purposes; and
neither the Company nor the Trustee nor any paying agent nor any conversion agent nor any Note registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being, or upon his order, shall be valid,
and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any such Note. 
  
 Section 9.04 Company-owned Notes Disregarded. In determining whether the holders of the requisite aggregate principal amount of Notes have
concurred in any direction, consent, waiver or other action under this Indenture, Notes which are owned by the Company or any other obligor on the Notes or any Affiliate of the Company or any other obligor on the Notes shall be disregarded

  

 58 

 and deemed not to be outstanding for the purpose of any such determination; provided, however, that, for
the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action, only Notes which a Responsible Officer knows are so owned shall be so disregarded. Notes so owned which have been
pledged in good faith may be regarded as outstanding for the purposes of this Section 9.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to vote such Notes and that the pledgee is not the Company, any
other obligor on the Notes or any Affiliate of the Company or any such other obligor. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of
the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons, and,
subject to Section 8.01 hereof, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any
such determination. Nothing herein shall prevent the Company or any of its Subsidiaries from tendering for or repurchasing any Notes, subject to applicable laws. 
  
 Section 9.05 Revocation of Consents, Future Holders Bound. At any time prior to (but not after) the evidencing to the
Trustee, as provided in Section 9.01 hereof, of the taking of any action by the holders of the percentage in aggregate principal amount of the Notes specified in this Indenture in connection with such action, any holder of a Note which is shown by
the evidence to be included in the Notes the holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 9.02 hereof, revoke such action
so far as concerns such Note. Except as aforesaid, any such action taken by the holder of any Note shall be conclusive and binding upon such holder and upon all future holders and owners of such Note and of any Notes issued in exchange or
substitution therefor, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor. 
  
 ARTICLE 10

by duly authorized representatives or have, before or after the meeting, waived notice.

 The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Noteholders as provided in Section 10.03 hereof, in which case the Company or the Noteholders calling the meeting, as the case may be, shall in like
manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the holders of a majority in principal amount of the Notes represented at the meeting and entitled to vote at the meeting.

  
 Subject to the provisions of Section 9.04 hereof, a quorum for

challenged as not outstanding and ruled by the chairman of the meeting to be not outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Notes held by him or instruments in writing as aforesaid duly designating
him as the proxy to vote on behalf of other Noteholders. Any meeting of Noteholders duly called pursuant to the provisions of Section 10.02 or 10.03 hereof may be adjourned from time to time by the holders of a majority of the aggregate principal

record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was mailed
as provided in Section 10.02 hereof. The record shall show the principal amount of the Notes voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the
meeting and one of the duplicates shall be delivered to the Company and the other to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. 
  
 Any record so signed and verified shall be conclusive evidence of the matters
therein stated. 
  
 Section 10.07 No Delay of Rights by
Meeting. Nothing contained in this Article 10 shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Noteholders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or

Event of Default permitting the enforcement of all or any of the several remedies provided in this Indenture as herein set forth; provided, however, 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; 
  
 (e) to
provide for the issuance under this Indenture of Notes in coupon form (including Notes registrable as to principal only) and to provide for exchangeability of such Notes with the Notes issued hereunder in fully registered form and to make all
appropriate changes for such purpose; 
  
 (f) to cure any
ambiguity 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, or to make such other provisions

 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. 
  

 63 

 Any supplemental indenture authorized by the provisions of this Section 11.01 hereof 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 11.02 hereof. 
  
 Notwithstanding any other provision of the Indenture or the Notes, the Registration Rights Agreement and the obligation to
pay Liquidated Damages thereunder may be amended, modified or waived in accordance with the provisions of the Registration Rights Agreement.

than 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

other than that provided in the Notes, or modify the provisions of this Indenture with respect to the subordination of the Notes in a manner adverse to the Noteholders in any material respect, or change the obligation of the Company to purchase any
Note upon the happening of a Fundamental Change in a manner adverse to the holder of Notes, or impair the right to convert the Notes into Common Stock subject to the terms set forth herein, including Sections 15.02. 15.06 and 15.07 hereof, in each
case, without the consent of the holder of each Note so affected, or (ii) reduce the aforesaid percentage of Notes, the holders of which are required to consent to any such supplemental indenture, or reduce the percentage of Notes, the holders of

 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 of Noteholders 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. 
  

 64 

 It shall not be necessary for the consent of the Noteholders under this Section 11.02 to approve the
particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof.

the Trust Indenture Act, as then in effect, provided that this Section 11.03 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 11 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 this Indenture for any and all purposes. 
  
 Section 11.04 Notation On Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article 11 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 pursuant to Section 16.11 hereof) and delivered in exchange
for the Notes then outstanding, upon surrender of such Notes then outstanding. 
  
 Section 11.05 Evidence Of Compliance Of Supplemental Indenture To Be Furnished To Trustee. Prior to entering into any supplemental indenture, the Trustee may request an Officers’ Certificate and an Opinion
of Counsel as conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this Article 11.

 ARTICLE 12 
 CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 
  
 Section 12.01 Company May Consolidate On Certain Terms. Subject to the provisions of Section 12.02 hereof, nothing
contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of the Company with or into any other Person or Persons (whether or not affiliated with the Company), or successive consolidations or mergers in which the
Company or its successor or successors shall be a party or parties, or shall prevent any sale, conveyance or lease (or successive sales, conveyances or leases) of all or substantially all of the property of the Company, to any other Person (whether
or not affiliated with the Company), authorized to acquire and operate the same and that shall be organized under the laws of the United States of America, any state thereof or the District of Columbia, or, if not organized in any such jurisdiction,
provided that (i) such Person agrees to be subject to the service of process laws of the State of New York and (ii) under the laws of such Person’s jurisdiction of organization, payments on the Notes (in cash or in shares of Common Stock
upon conversion of the Notes) would not be subject to withholding tax; provided, however, that upon any such consolidation, merger, sale, conveyance or lease, the due and punctual payment of the principal of and premium, if any, and interest
(including Liquidated Damages, if any) on all of the Notes, according to their tenor and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed by the Company, shall be expressly
assumed, by supplemental indenture satisfactory in form to the Trustee, executed and delivered to the Trustee by the Person (if other than the Company) formed by such consolidation, or into which the Company shall have been merged, or by the Person
that shall have acquired or leased such property, and such supplemental indenture shall provide for the applicable conversion rights set forth in Section 15.07 hereof. 
  
 Section 12.02 Successor Corporation To Be Substituted. In case of any such consolidation, merger, sale, conveyance or
lease and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and premium, if any, and interest on
all of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company, such successor Person shall succeed to and be substituted for the Company, with the same effect as if it
had been named herein as the party of this first part. Such successor Person thereupon may cause to be signed, and may issue either in its own name or in the name of Kulicke and Soffa Industries, Inc. (if such name is generally used by such
successor Person) any or all of the Notes, issuable hereunder that theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor Person instead of the Company and subject to all the

  

 66 

 terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or
cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the officers of the Company to the Trustee for authentication, and any Notes that such successor Person thereafter shall cause to be signed
and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as
though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale or conveyance, the Person named as the “Company” in the first paragraph of this Indenture or any
successor that shall thereafter have become such in the manner prescribed in this Article 12 shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture and at any time thereafter such
Person may, but is not bound to, be dissolved, wound up and liquidated. The foregoing sentence shall not apply in the event of a lease of all or substantially all of the property of the Company or of any successor to the Company under this Article
12. 
  
 In case of any such consolidation, merger, sale,
conveyance or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate. 
  
 Section 12.03 Opinion Of Counsel To Be Given Trustee. The Trustee shall receive an Officers’ Certificate and an Opinion of Counsel as
conclusive evidence that any such consolidation, merger, sale, conveyance or lease and any such assumption complies with the provisions of this Article 12. 
  
 ARTICLE 13 
 SATISFACTION
AND DISCHARGE OF INDENTURE 
  
 Section 13.01 Discharge Of Indenture. When (a) the Company shall deliver to the Trustee for cancellation all Notes theretofore authenticated (other than any Notes that have been destroyed, lost or stolen and in
lieu of or in substitution for which other Notes shall have been authenticated and delivered) and not theretofore canceled, or (b) all the Notes not theretofore canceled or delivered to the Trustee for cancellation shall have become due and payable,
or are by their terms to become due and payable within one year, and the Company shall deposit with the Trustee, in trust, funds sufficient to pay at maturity or upon redemption of all of the Notes (other than any Notes that shall have been
mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) not theretofore canceled or delivered to the Trustee for cancellation, the principal and premium, if any, and
interest due or to become due to such date of maturity or redemption date, as the 
  

 67 

 case may be, accompanied by a verification report, as to the sufficiency of the deposited amount, from an independent
certified accountant or other financial professional satisfactory to the Trustee, and if the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this Indenture shall cease to be of further effect (except
as to (i) remaining rights of registration of transfer, substitution and exchange and conversion of Notes, (ii) rights hereunder of Noteholders to receive payments of principal of and premium, if any, and interest (including Liquidated Damages, if
any) on, the Notes and the other rights, duties and obligations of Noteholders, as beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee and (iii) the rights, obligations and immunities of the Trustee hereunder),
and the Trustee, on written demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel as required by Section 16.05 hereof and at the cost and expense of the Company, shall execute proper instruments acknowledging
satisfaction of and discharging this Indenture; the Company, however, hereby agrees to reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred by the Trustee and to compensate the Trustee for any services
thereafter reasonably and properly rendered by the Trustee in connection with this Indenture or the Notes. 
  
 Section 13.02 Deposited Monies To Be Held In Trust By Trustee. Subject to Section 13.04 hereof, all monies deposited with the Trustee pursuant to
Section 13.01 hereof, provided such deposit was not in violation of Article 4, shall be held in trust for the sole benefit of the Noteholders and not to be subject to the subordination provisions of Article 4, 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 (including Liquidated Damages, if any) and premium, if any. 
  
 Section 13.03 Paying Agent To Repay Monies Held. Upon the satisfaction and discharge of this Indenture, all monies then held by any paying agent of
the Notes (other than the Trustee) shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such paying agent shall be released from all further liability with respect to such monies. 
  
 Section 13.04 Return Of Unclaimed Monies. Subject to the requirements
of applicable law, any monies deposited with or paid to the Trustee for payment of the principal of, premium, if any, or interest (including Liquidated Damages, if any) on Notes and not applied but remaining unclaimed by the holders of Notes for two
years after the date upon which the principal of, premium, if any, or interest (including Liquidated Damages, if any) on such Notes, as the case may be, shall have become due and payable, shall be repaid to the Company by the 
  

 68 

 Trustee on demand and all liability of the Trustee shall thereupon cease with respect to such monies; and the holder of
any of the Notes shall thereafter look only to the Company for any payment that such holder may be entitled to collect unless an applicable abandoned property law designates another Person. 
  
 Section 13.05 Reinstatement. If the Trustee or the paying agent is
unable to apply any money in accordance with Section 13.02 hereof by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 13.01 hereof until such time as the Trustee or the paying agent is permitted to apply all such money in accordance with Section 13.02
hereof; provided, however, that if the Company makes any payment of interest (including Liquidated Damages, if any) 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 14 
 IMMUNITY OF INCORPORATORS,
STOCKHOLDERS, OFFICERS AND DIRECTORS 
  
 Section 14.01 Indenture And Notes Solely Corporate Obligations. No recourse for the payment of the principal of or premium, if any, or interest on
any Note, or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company in this Indenture or in any supplemental indenture or in any Note, or because of the
creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer, director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly
or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is hereby
expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issue of the Notes. 
  
 ARTICLE 15 
 CONVERSION
OF NOTES 
  
 Section 15.01 Right
To Convert. Subject to and upon compliance with the provisions of this Indenture, including, without limitation, Article 4, the holder of any Note shall have the right, to the extent that a Conversion Termination has not occurred pursuant to
Section 15.02 of this Indenture, at its 
  

 69 

 option, at any time through the close of business on the final maturity date of the Notes to convert each $1,000
principal amount of the Notes into a number of fully paid and non-assessable shares of Common Stock (as such shares shall then be constituted) equal to the Conversion Rate in effect at such time, by surrender of the Note so to be converted in whole
or in part in the manner provided, together with any required funds, in Section 15.03 hereof. A Note in respect of which a holder is exercising its option to require purchase upon a Fundamental Change pursuant to Section 15.03 hereof may be
converted only if such holder withdraws its election to exercise in accordance with Section 3.02(b) hereof. If a holder surrenders its Notes (or any portion thereof) for conversion after receipt of a Company Notice and prior to the Purchase Date,
and the Fundamental Change related to the Company Notice constitutes a Cash Buy-Out, the Company will pay a Make-Whole Premium to such holder as provided for in Section 3.02, in addition to the shares of Common Stock deliverable upon conversion of
the Notes. A holder of Notes is not entitled to any rights of a holder of Common Stock until such holder has converted his Notes to Common Stock, and only to the extent such Notes are deemed to have been converted to Common Stock under this Article
15. 
  
 Section 15.02 Termination of Conversion Right. The
Company may terminate the right of holders to convert their Notes into Common Stock (the “Conversion Right”), at any time on or after June 30, 2006, if the Closing Price of the Common Stock has exceeded 140% of the Conversion Price
then in effect for at least 20 Trading Days within a period of 30 consecutive Trading Days (a “Conversion Termination Trigger Event”). If the Company elects to terminate the Conversion Right upon a Conversion Termination Trigger
Event, then the Company will be required to deliver an irrevocable notice to record holders of Notes within five Trading Days of the date of the applicable Conversion Termination Trigger Event (the “Conversion Termination Notice,”
and the date of such Conversion Termination Notice, the “Conversion Termination Notice Date”). Holders may convert their Notes at any time on or prior to the twentieth (20th) day following the Conversion Termination Notice Date (the “Conversion Termination Date”). The Conversion Rights of all holders shall
terminate after the Conversion Termination Date (a “Conversion Termination”), and thereafter the holders shall have no rights to convert and receive shares of Common Stock under the Notes or this Indenture. 
  
 The Company will not be required to make any interest payment on an interest
payment date with respect to any Note that is surrendered for conversion after the Conversion Termination Notice Date and prior to the Conversion Termination Date on a Conversion Date that is between a record date for the payment of interest to the
next succeeding interest payment date; provided, however, in the case of the June 30, 2006 interest payment, if the Company has elected to terminate the Conversion Right, the Company will be required to make 
  

 70 

 such June 30, 2006 interest payment with respect to Notes surrendered for conversion on a Conversion Date that is during
the five day period prior to the June 30, 2006. 
  
 The Company
shall mail the Conversion Termination Notice to the Trustee and to each record holder. The Conversion Termination Notice shall include the form of the conversion notice to be completed by the holder and shall state: 
  

	 	(1)	the Conversion Termination Date; 

  

	 	(2)	the Conversion Price then in effect; 

  

	 	(3)	briefly, the conversion rights of the Notes; 

  

	 	(4)	the name and address of each paying agent and conversion agent; and 

  

	 	(5)	the Conversion Rate and any adjustments thereto. 

  
 Concurrently with or before the mailing of the Conversion Termination Notice, the Company shall issue a press release announcing such Conversion
Termination Trigger Event referred to in the Conversion Termination Notice, the form and content of which press release shall be determined by the Company in its sole discretion. 
  
 Whenever in this Indenture or in the Notes there is a reference, in any context, to any conversion obligation of the
Company, such reference shall be qualified by the conversion termination provisions of this Section 15.02, and the Company will not be required to comply with any of the conversion provisions of this Indenture or the Notes (including, without
limitation, Article 15 (other than this Section 15.02)) after a Conversion Termination has occurred pursuant to the provisions of this Section 15.02, and any express mention of the conversion termination provisions of this Section 15.02 in any
provision of this Indenture shall not be construed as excluding the conversion termination provisions of this Section 15.02 in those provisions of this Indenture when such express mention is not made. 
  
 Section 15.03 Exercise Of Conversion Privilege; Issuance Of Common Stock
On Conversion, No Adjustment For Interest Or Dividends. In order to exercise the conversion privilege with respect to any Note in certificated form, the holder of any such Note to be converted in whole or in part shall surrender such Note, duly
endorsed, at an office or agency maintained by the Company pursuant to Section 5.02 hereof, accompanied by the funds, if any, required by the penultimate paragraph of this Section 15.03, and shall give written notice of 
  

 71 

 conversion in the form provided on the Notes (or such other notice which is acceptable to the Company) to the office or
agency that the holder elects to convert such Note or the portion thereof specified in said notice. Such notice shall also state the name or names (with address or addresses) in which the certificate or certificates for shares of Common Stock which
shall be issuable on such conversion shall be issued, and shall be accompanied by transfer taxes, if required pursuant to Section 15.08 hereof. Each such Note surrendered for conversion shall, unless the shares issuable on conversion are to be
issued in the same name as the registration of such Note, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the holder or his duly authorized attorney. 
  
 In order to exercise the conversion privilege with respect to any interest in
a Global Note, the beneficial holder must complete, or cause to be completed, the appropriate instruction form for conversion pursuant to the Depositary’s book-entry conversion program, deliver, or cause to be delivered, by book-entry delivery
an interest in such Global Note, furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or conversion agent, and pay the funds, if any, required by this Section 15.03 and any transfer taxes if required
pursuant to Section 15.08 hereof. 
  
 As promptly as practicable
after satisfaction of the requirements for conversion set forth above, subject to compliance with any restrictions on transfer if shares issuable on conversion are to be issued in a name other than that of the Noteholder (as if such transfer were a
transfer of the Note or Notes (or portion thereof) so converted), the Company shall issue and shall deliver to such Noteholder at the office or agency maintained by the Company for such purpose pursuant to Section 5.02, a certificate or certificates
for the number of full shares of Common Stock issuable upon the conversion of such Note or portion thereof as determined by the Company in accordance with the provisions of this Article 15 and a check or cash in respect of any fractional interest in
respect of a share of Common Stock arising upon such conversion, calculated by the Company as provided in Section 15.04 hereof. In case any Note of a denomination greater than $1,000 shall be surrendered for partial conversion, and subject to
Section 2.03 hereof, the Company shall execute and the Trustee shall authenticate and deliver to the holder of the Note so surrendered, without charge to him, a new Note or Notes in authorized denominations in an aggregate principal amount equal to
the unconverted portion of the surrendered Note. 
  
 Each
conversion shall be deemed to have been effected as to any such Note (or portion thereof) on the date on which the requirements set forth above in the first two paragraphs of this Section 15.03 have been satisfied as to such Note (or portion
thereof) (such date of effectiveness, the “Conversion Date”), and the Person in whose name any certificate or certificates for shares of Common Stock 
  

 72 

 shall be issuable upon such conversion shall be deemed to have become on said date the holder of record of the shares
represented thereby; provided, however, that any such surrender on any date when the stock transfer books of the Company shall be closed shall constitute the Person in whose name the certificates are to be issued as the record holder thereof
for all purposes on the next succeeding day on which such stock transfer books are open, but such conversion shall be at the Conversion Rate in effect on the date upon which such Note shall be surrendered. 
  
 No adjustment in respect of interest on any Note converted or dividends on
any shares issued upon conversion of such Note will be made upon any conversion except as provided herein. If such Note (or portion thereof) is surrendered for conversion during the period from the close of business on any record date for the
payment of interest to the close of business on the Business Day preceding the following interest payment date, such Note (or portion being converted) must be accompanied by an amount, in New York Clearing House funds or other funds acceptable to
the Company, equal to the interest payable on such interest payment date on the principal amount being converted; provided, however, that no such payment shall be required if there shall exist at the time of conversion a default in the
payment of interest on the Notes or if, in the case of the June 30, 2006 interest payment, the Company has elected to terminate the Conversion Right pursuant to Section 15.02 and such Note is surrendered for conversion during the five day period
prior to June 30, 2006. If any Note (or portion thereof) is submitted for conversion on an interest payment date or on the final maturity date, the interest payable on such date shall be paid to the holder of record as of the close of business on
the immediately preceding record date. 
  
 Upon the conversion of
an interest in a Global Note, the Trustee (or other conversion agent appointed by the Company), or the Custodian at the direction of the Trustee (or other conversion agent appointed by the Company), shall make a notation on such Global Note as to
the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Notes effected through any conversion agent other than the Trustee. 
  
 Section 15.04 Cash Payments In Lieu Of Fractional Shares. No
fractional shares of Common Stock or scrip representing fractional shares shall be issued upon conversion of Notes. If more than one Note shall be surrendered for conversion at one time by the same holder, the number of full shares that shall be
issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share of stock would be issuable upon the
conversion of any Note or Notes, the Company shall make an adjustment and payment therefor in cash at the current market price thereof to the 
  

 73 

 holder of Notes. The current market price of a share of Common Stock shall be the Closing Price on the last Business Day
immediately preceding the day on which the Notes (or specified portions thereof) are deemed to have been converted. 
  
 Section 15.05 Conversion Rate. Each $1,000 principal amount of the Notes shall be convertible into the number of shares of Common Stock specified
in the form of Note (the “Conversion Rate”) attached as Exhibit A hereto, subject to adjustment as provided in this Article 15. 
  
 Section 15.06 Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows: 
  
 (a) In case the Company shall hereafter pay a dividend or make a
distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Rate shall be increased so that the same shall equal the rate determined by dividing the Conversion Rate in effect at the opening of business on
the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution by a fraction, 
  
 (i) the numerator of which shall be the number of shares of the Common Stock outstanding at the close of business on the date fixed for
such determination; and 
  
 (ii) the denominator
of which shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, 
  
 such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purpose of this Section
15.06(a), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the
Company. If any dividend or distribution of the type described in this Section 15.06(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or
distribution had not been declared. 
  
 (b) In case the Company
shall issue rights or warrants to all holders of its outstanding shares of Common Stock entitling them (for a period expiring within 45 days after the date fixed for determination of stockholders entitled to receive such rights or warrants) to
subscribe for or purchase shares of Common Stock at a price per share less than the Current Market Price (as defined below) on the date fixed for determination of stockholders entitled to receive such rights or warrants, the Conversion Rate shall be
adjusted so that the same shall equal the 
  

 74 

 rate determined by dividing the Conversion Rate in effect immediately prior to the date fixed for determination of
stockholders entitled to receive such rights or warrants by a fraction, 
  
 (i) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for determination of stockholders entitled to receive such rights or warrants plus the
number of shares that the aggregate offering price of the total number of shares so offered would purchase at such Current Market Price, and 
  
 (ii) the denominator of which shall be the number of shares of Common Stock outstanding on the date fixed for determination of
stockholders entitled to receive such rights or warrants plus the total number of additional shares of Common Stock offered for subscription or purchase. 
  
 Such adjustment shall be successively made whenever any such rights or warrants are issued, and shall become effective immediately after the opening of
business on the day following the date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock are not delivered after the expiration of such rights or warrants, the Conversion
Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. In
the event that such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such date fixed for the determination of stockholders entitled to receive such rights or
warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares
of Common Stock, there shall be taken into account any consideration received by the Company for such rights or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined
by the Board of Directors. 
  
 (c) (i) In case outstanding shares
of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately
increased, and (ii) in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination
becomes effective shall be proportionately reduced. Any such increase or reduction, as the case may be, shall become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes
effective. 
  

 75 

 (d) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock
shares of any class of capital stock of the Company or evidences of its indebtedness or assets (including securities, but excluding any rights or warrants referred to in Section 15.06(b) hereof, and excluding any dividend or distribution (x) paid
exclusively in cash or (y) referred to in Section 15.06(a) hereof (any of the foregoing hereinafter in this Section 15.06(d) called the “Securities”)), then, in each such case (unless the Company elects to reserve such Securities
for distribution to the Noteholders upon the conversion of the Notes so that any such holder converting Notes will receive upon such conversion, in addition to the shares of Common Stock to which such holder is entitled, the amount and kind of such
Securities which such holder would have received if such holder had converted its Notes into Common Stock immediately prior to the Record Date (as defined in Section 15.06(h)(iv) hereof for such distribution of the Securities)), the Conversion Rate
shall be adjusted so that the same shall be equal to the rate determined by dividing the Conversion Rate in effect on the Record Date with respect to such distribution by a fraction, 
  
 (i) the numerator of which shall be the Current Market Price per share of the Common Stock on such Record
Date less the Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors) on the Record Date of the portion of the Securities so distributed applicable
to one share of Common Stock; and 
  
 (ii) the
denominator of which shall be the Current Market Price per share of the Common Stock, 
  
 such adjustment to become effective immediately prior to the opening of business on the day following such Record Date; provided, however, that in the event the then Fair Market Value (as so determined) of the portion of the
Securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Common Stock on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each
Noteholder shall have the right to receive upon conversion the amount of Securities such holder would have received had such holder converted each Note on the Record Date. In the event that such dividend or distribution is not so paid or made, the
Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the Fair Market Value of any distribution for purposes of
this Section 15.06(d) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price of the Common Stock.

  

 76 

 Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders
thereof to subscribe for or purchase shares of the Company’s capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i)
are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 15.06 (and
no adjustment to the Conversion Rate under this Section 15.06 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is
required) to the Conversion Rate shall be made under this Section 15.06(d). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of
which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date
with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of
rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under
this Section 15.06 was made, (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to
give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or
warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or been terminated
without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued. 
  
 No adjustment of the Conversion Rate shall be made pursuant to this Section 15.06(d) in respect of rights or warrants distributed or deemed distributed on
any Trigger Event to the extent that such rights or warrants are actually distributed, or reserved by the Company for distribution to holders of Notes upon conversion by such holders of Notes to Common Stock. 
  

 77 

 For purposes of this Section 15.06(d) and Sections 15.06(a) and 15.06(b) hereof, any dividend or
distribution to which this Section 15.06(d) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock (or both), shall be deemed instead to be (1) a dividend or distribution of
the evidences of indebtedness, assets or shares of capital stock other than such shares of Common Stock or rights or warrants (and any Conversion Rate adjustment required by this Section 15.06(d) with respect to such dividend or distribution shall
then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Rate adjustment required by Sections 15.06(a) and 15.06(b) hereof with respect to such
dividend or distribution shall then be made), except (A) the Record Date of such dividend or distribution shall be substituted as “the date fixed for the determination of stockholders entitled to receive such dividend or other
distribution”, “the date fixed for the determination of stockholders entitled to receive such rights or warrants” and “the date fixed for such determination” within the meaning of Sections 15.06(a) and 15.06(b) hereof, and
(B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of business on the date fixed for such determination” within the meaning of Section 15.06(a) hereof. 
  
 (e) In case the Company shall, by dividend or otherwise, distribute to all
holders of its Common Stock cash (excluding any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary), then, in such case, the Conversion Rate shall be increased so
that the Conversion Rate shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the Record Date for such dividend or distribution by a fraction, 
  
 (i) the numerator of which shall be the average of the
Closing Prices of the Common Stock for the three consecutive Trading Days ending on the Trading Day immediately preceding the ex-dividend date for such dividend or distribution (the “Pre-Dividend Sale Price”), and 
  
 (ii) the denominator of which shall be the Pre-Dividend Sale
Price, minus the full amount of such cash dividend or distribution applicable to one share of Common Stock, 
  
 such adjustment to become effective on the Business Day next following the ex-dividend date for such dividend or distribution; provided that no adjustment to the Conversion Rate or the ability of a holder of a
Note to convert will be made pursuant to this Section 15.06(e) if the Company provides that holders of Notes will participate in such cash dividend or distribution on an as-converted basis without conversion; provided, further, that if
the denominator of the foregoing fraction is less than $1.00 (including a negative amount), then in lieu of the 
  

 78 

 foregoing adjustment, adequate provision shall be made so that each holder shall have the right to receive upon
conversion, in addition to the Common Stock issuable upon such conversion, the amount of cash such holder would have received had such holder converted its Note immediately prior to the Record Date for such dividend or distribution. If such dividend
or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
  
 (f) In case a tender or exchange offer made by the Company or any Subsidiary
for all or any portion of the Common Stock shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders of consideration per share of Common Stock having a Fair Market Value (as
determined by the Board of Directors, whose determination shall be conclusive and described in a resolution of the Board of Directors) that as of the last time (the “Expiration Time”) tenders or exchanges may be made pursuant to
such tender or exchange offer (as it may be amended) exceeds the last reported sale price of the Common Stock (determined as provided in the definition of Current Market Price) on the Trading Day next succeeding the Expiration Time, the Conversion
Rate shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the Expiration Time by a fraction 
  
 (i) the numerator of which shall be the sum of (x) the Fair Market Value (determined as aforesaid) of the
aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares
deemed so accepted up to any such maximum, being referred to as the “Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) at the Expiration Time and the last reported
sale price of the Common Stock (determined as provided in the definition of Current Market Price) on the Trading Day next succeeding the Expiration Time, and 
  

(ii) the denominator of which shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) at
the Expiration Time multiplied by last reported sale price of the Common Stock (determined as provided in the definition of the Current Market Price) on the Trading Day next succeeding the Expiration Time 
  
 such adjustment to become effective immediately prior to the opening of business on the day
following the Expiration Time. In the event that the Company is obligated to purchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from effecting any such 
  

 79 

 purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that
would then be in effect if such tender or exchange offer had not been made. 
  
 (g) In case of a tender or exchange offer made by a Person other than the Company or any Subsidiary for an amount that increases the offeror’s ownership of Common Stock to more than 25% of the Common Stock
outstanding and shall involve the payment by such Person of consideration per share of Common Stock having a Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the
Board of Directors) as of the last time (the “Offer Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it shall have been amended) that exceeds the last reported sale price of the Common
Stock (determined as provided in the definition of the Current Market Price) on the Trading Day next succeeding the Offer Expiration Time, and in which, as of the Offer Expiration Time the Board of Directors is not recommending rejection of the
offer, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the Offer Expiration Time by a fraction 
  
 (i) the numerator of which shall be the sum of (x) the Fair
Market Value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not
withdrawn as of the Offer Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the “Accepted Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less
any Accepted Purchased Shares) at the Offer Expiration Time and the last reported sale price of the Common Stock (determined as provided in the definition of the Current Market Price) on the Trading Day next succeeding the Offer Expiration Time, and

  
 (ii) the denominator of which shall be the
number of shares of Common Stock outstanding (including any tendered or exchanged shares) at the Offer Expiration Time multiplied by the last reported sale price of the Common Stock (determined as provided in the definition of the Current Market
Price) on the Trading Day next succeeding the Offer Expiration Time, 
  
 such
adjustment to become effective immediately prior to the opening of business on the day following the Offer Expiration Time. In the event that such Person is obligated to purchase shares pursuant to any such tender or exchange offer, but such Person
is permanently prevented by applicable law from effecting any such 
  

 80 

 purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that
would then be in effect if such tender or exchange offer had not been made. Notwithstanding the foregoing, the adjustment described in this Section 15.06(g) shall not be made if, as of the Offer Expiration Time, the offering documents with respect
to such offer disclose a plan or intention to cause the Company to engage in any transaction described in Article 12. 
  
 (h) For purposes of this Section 15.06, the following terms shall have the meaning indicated: 
  
 (i) “Closing Price” with respect to any
security on any day shall mean the closing sale price, regular way, on such day or, in case no such sale takes place on such day, the average of the reported closing bid and asked prices, regular way, in each case as quoted on the Nasdaq National
Market or, if such security is not quoted or listed or admitted to trading on such Nasdaq National Market, on the principal national securities exchange or quotation system on which such security is quoted or listed or admitted to trading or, if not
quoted or listed or admitted to trading on any national securities exchange or quotation system, the average of the closing bid and asked prices of such security on the over-the-counter market on the day in question as reported by the National
Quotation Bureau Incorporated, or a similar generally accepted reporting service, or if not so available, in such manner as furnished by any New York Stock Exchange member firm selected from time to time by the Board of Directors for that purpose,
or a price determined in good faith by the Board of Directors or, to the extent permitted by applicable law, a duly authorized committee thereof, whose determination shall be conclusive. 
  
 (ii) “Current Market Price” shall mean the average of the daily Closing Prices per share of
Common Stock for the 10 consecutive Trading Days selected by the Company commencing no more than 30 Trading Days before and ending not later than the earlier of such date of determination and the day before the “ex” date with respect to
the issuance, distribution, subdivision or combination requiring such computation immediately prior to the date in question. For purpose of this paragraph 15.06(h)(ii), the term “ex” date, (1) when used with respect to any issuance or
distribution, means the first date on which the Common Stock trades, regular way, on the relevant exchange or in the relevant market from which the Closing Price was obtained without the right to receive such issuance or distribution, and (2) when
used with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades, regular way, on such exchange or in such market after the time at which such subdivision or combination becomes
effective. 
  

 81 

 In the event that another issuance, distribution, subdivision, combination or tender or exchange offer to
which this Section 15.06 applies occurs during the period applicable for calculating “Current Market Price” pursuant to the definition in the preceding paragraph, “Current Market Price” shall be calculated for such
period in a manner determined by the Board of Directors to reflect the impact of such issuance, distribution, subdivision, combination or tender or exchange offer on the Closing Price of the Common Stock during such period. 
  
 (iii) “Fair Market Value” shall mean the
amount which a willing buyer would pay a willing seller in an arm’s-length transaction. 
  
 (iv) “Record Date” shall mean, with respect to any dividend, distribution or other transaction or event in which the
holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date
fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). 
  
 (v) “Trading Day” shall mean (x) if the
applicable security is quoted on the Nasdaq National Market, a day on which trades may be made thereon or (y) if the applicable security is listed or admitted for trading on the New York Stock Exchange or another national securities exchange, a day
on which the New York Stock Exchange or another national securities exchange is open for business or (z) if the applicable security is not so listed, admitted for trading or quoted, any day other than a Saturday or Sunday or a day on which banking
institutions in the State of New York are authorized or obligated by law or executive order to close. 
  
 (i) The Company may make such increases in the Conversion Rate, in addition to those required by Sections 15.06(a), (b), (c), (d), (e), (f) and (g) hereof
as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event
treated as such for income tax purposes. 
  
 To the extent
permitted by applicable law, the Company from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least 20 days, the increase is irrevocable during the period and the Board of Directors shall have
made a determination that such increase would be 
  

 82 

 in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion Rate is increased
pursuant to the preceding sentence, the Company shall mail to holders of record of the Notes a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion
Rate and the period during which it will be in effect. 
  
 Any
adjustment made pursuant to this Section 15.06(i) will not be made without first obtaining shareholder approval if such approval is required by law or the Nasdaq listing standards. 
  
 (j) All calculations under this Article 15 shall be made by the Company and shall be made to the nearest cent or to the
nearest 1/10,000 of a share, as the case may be. No adjustment need be made for rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest. To the extent the Notes become convertible into cash, assets,
property or securities (other than capital stock of the Company), no adjustment need be made thereafter as to the cash, assets, property or such securities. Interest will not accrue on the cash. 
  
 (k) Whenever the Conversion Rate is adjusted as herein provided, the Company
shall promptly file with the Trustee and any conversion agent other than the Trustee an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment.
Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of
which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment
becomes effective and shall mail such notice of such adjustment of the Conversion Rate to the holder of each Note at his last address appearing on the Note register provided for in Section 2.05 hereof, within 20 days after execution thereof. Failure
to deliver such notice shall not affect the legality or validity of any such adjustment. 
  
 (l) In any case in which this Section 15.06 provides that an adjustment shall become effective immediately after (1) a record date or Record Date for an event, (2) the date fixed for the determination of stockholders
entitled to receive a dividend or distribution pursuant to Section 15.06(a) hereof, (3) a date fixed for the determination of stockholders entitled to receive rights or warrants pursuant to Section 15.06(b) hereof, (4) the Expiration Time for any
tender or exchange offer pursuant to Section 15.06(f) hereof, or (5) the Offer Expiration Time for a tender or exchange offer pursuant to Section 15.06(g) hereof (each a “Determination Date”), the Company may elect to defer until
the occurrence of the relevant 
  

 83 

 Adjustment Event (as hereinafter defined) (x) issuing to the holder of any Note converted after such Determination Date
and before the occurrence of such Adjustment Event, the additional shares of Common Stock or other securities issuable upon such conversion by reason of the adjustment required by such Adjustment Event over and above the Common Stock issuable upon
such conversion before giving effect to such adjustment and (y) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 15.04 hereof. For purposes of this Section 15.06(l), the term “Adjustment Event”
shall mean: 
  
 (i) in any case referred to in
Section 15.06(l)(1) hereof, the occurrence of such event, 
  
 (ii) in any case referred to in Section 15.06(l)(2) hereof, the date any such dividend or distribution is paid or made, 
  
 (iii) in any case referred to in Section 15.06(l)(3) hereof, the date of expiration of such rights or warrants, and 
  
 (iv) in any case referred to in Section 15.06(l)(4) or
Section 15.06(l)(5) hereof, the date a sale or exchange of Common Stock pursuant to such tender or exchange offer is consummated and becomes irrevocable. 
  
 (m) For purposes of this Section 15.06, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the
Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the
Company. 
  
 Section 15.07 Effect Of Reclassification,
Consolidation, Merger Or Sale. If any of the following events occur, namely (i) any reclassification or change of the outstanding shares of Common Stock (other than a subdivision or combination to which Section15.06(c) hereof applies), as a
result of which holders of Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, (ii) any consolidation, merger or combination of the
Company with another Person as a result of which holders of Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, or (iii) any sale or
conveyance of all or substantially all of the properties and assets of the Company to any other Person as a result of which holders of Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash)
with respect to or in exchange for such Common Stock, then the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a 
  

 84 

 supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such
supplemental indenture) providing that each Note shall be convertible into the kind and amount of shares of stock, other securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger,
combination, sale or conveyance by a holder of a number of shares of Common Stock issuable upon conversion of such Notes (assuming, for such purposes, a sufficient number of authorized shares of Common Stock are available to convert all such Notes)
immediately prior to such reclassification, change, consolidation, merger, combination, sale or conveyance assuming such holder of Common Stock did not exercise his rights of election, if any, as to the kind or amount of stock, other securities or
other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance (provided that, if the kind or amount of stock, other securities or other property or assets
(including cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised
(“Nonelecting Share”), then for the purposes of this Section 15.07 the kind and amount of stock, other securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger,
combination, sale or conveyance for each Nonelecting Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Nonelecting Shares). Such supplemental indenture shall provide for adjustments which shall be as
nearly equivalent as may be practicable to the adjustments provided for in this Article 15. 
  
 The Company shall cause notice of the execution of such supplemental indenture to be mailed to each holder of Notes, at its address appearing on the Note register provided for in Section 2.05 hereof, within 20 days
after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. 
  
 The above provisions of this Section shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales and
conveyances. 
  
 If this Section 15.07 applies to any event or
occurrence, Section 15.06 hereof shall not apply. 
  
 Section
15.08 Taxes On Shares Issued. The issue of stock certificates on conversions of Notes shall be made without charge to the converting Noteholder for any tax in respect of the issue thereof. The Company shall not, however, be required to pay
any tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the holder of any Note converted, and the Company shall not be required to issue or deliver any 
  

 85 

 such stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Company
the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 
  
 Section 15.09 Reservation Of Shares, Shares To Be Fully Paid; Compliance With Governmental Requirements; Listing Of Common Stock. The Company shall
provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of the Notes from time to time as such Notes are presented for conversion.

  
 Before taking any action which would cause an adjustment
increasing the Conversion Rate to an amount that would cause the Conversion Price to be reduced below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Notes, the Company will take all corporate action which
may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such Common Stock at such adjusted Conversion Rate. 
  
 The Company covenants that all shares of Common Stock which may be issued upon conversion of Notes will upon issue be fully
paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 
  
 The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration with or
approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will in good faith and as expeditiously as possible, to the extent then permitted by the rules and
interpretations of the Securities and Exchange Commission (or any successor thereto), endeavor to secure such registration or approval, as the case may be. 
  
 The Company further covenants that, if at any time the Common Stock shall be listed on the Nasdaq National Market or any other national securities
exchange or automated quotation system, the Company will, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system,
all Common Stock issuable upon conversion of the Notes; provided, however, that, if the rules of such exchange or automated quotation system permit the Company to defer the listing of such Common Stock until the first conversion of the Notes
into Common Stock in accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Notes in accordance with the requirements of such exchange or automated quotation system at such
time. 
  

 86 

 Section 15.10 Responsibility Of Trustee. The Trustee and any other conversion agent shall not at
any time be under any duty or responsibility to any holder of Notes to determine the Conversion Rate or whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent or calculation of any
such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other conversion agent shall not be accountable with respect to the
validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other conversion agent make no
representations with respect thereto. Neither the Trustee nor any conversion agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or
cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 15. Without limiting the generality of the foregoing, neither the Trustee
nor any conversion agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 15.07 hereof relating either to the kind or amount of shares of stock
or securities or property (including cash) receivable by Noteholders upon the conversion of their Notes after any event referred to in Section 15.07 hereof or to any adjustment to be made with respect thereto, but, subject to the provisions of
Section 8.01 hereof, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the
execution of any such supplemental indenture) with respect thereto. 
  
 Section 15.11 Notice To Holders Prior To Certain Actions. In case: 
  
 (a) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Conversion Rate pursuant to Section 15.06 hereof; or 
  
 (b) the Company shall authorize the granting to the holders of all or
substantially all of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants; or 
  
 (c) of any reclassification or reorganization of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock,
or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale
or transfer of all or substantially all of the assets of the Company; or 
  

 87 

 (d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; 
  
 the Company shall cause to be filed with the Trustee and to be mailed to each holder of Notes
at his address appearing on the Note register provided for in Section 2.05 hereof, as promptly as possible 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, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined,
or (y) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record
shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. Failure to give such notice, or any defect
therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. 
  
 Section 15.12 Rights Issued In Respect Of Common Stock Issued Upon Conversion. Each share of Common Stock issued upon
conversion of Notes pursuant to this Article 15 shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as
may be provided by the terms of any shareholder rights agreement adopted by the Company, as the same may be amended from time to time (in each case, a “Rights Agreement”).

 Section 16.07 Trust Indenture Act. This 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; provided, however, that, unless otherwise required by law, notwithstanding the foregoing, this Indenture and the Notes issued hereunder shall not be

included in an indenture qualified under the Trust Indenture Act, such required provision shall control. 
  
 Section 16.08 No Security Interest Created. Nothing in this Indenture or in the Notes, expressed or implied, shall be construed to constitute a

 Section 16.09 Benefits Of Indenture. Nothing in this Indenture or in
the Notes, express or implied, shall give to any Person, other than the parties hereto, any paying agent, any authenticating agent, any Note registrar and their successors hereunder, the holders of Notes and the holders of Senior Indebtedness, any
benefit or any legal or equitable right, remedy or claim under this Indenture.

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

further act on the part of the parties hereto or the authenticating agent or such successor corporation. 
  
 Any authenticating agent may at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time
terminate the agency of any authenticating agent by giving written notice of termination to such authenticating agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any
authenticating agent shall cease to be eligible under this Section, the Trustee shall either promptly appoint a successor authenticating agent or itself assume the duties and obligations of the former authenticating agent under this Indenture and,
upon such appointment of a successor authenticating agent, if made, shall give written notice of such appointment of a successor authenticating agent to the Company and shall mail notice of such appointment of a successor authenticating agent to all
holders of Notes as the names and addresses of such holders appear on the Note register. 
  

 91 

 The Company agrees to pay to the authenticating agent from time to time such reasonable compensation for
its services as shall be agreed upon in writing between the Company and the authenticating agent. 
  
 The provisions of Sections 8.02, 8.03, 8.04 and 9.03 hereof and this Section 16.11 shall be applicable to any authenticating agent. 
  
 Section 16.12 Execution In Counterparts. This Indenture may be
executed in any number of counterparts, each of which shall be an original, but such counterparts shall together constitute but one and the same instrument. 
  
 Section 16.13 Severability. In case any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable, then (to the extent
permitted by law) the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

 FORM OF REVERSE OF NOTE 
  
 KULICKE AND SOFFA INDUSTRIES, INC. 
  
 1% CONVERTIBLE SUBORDINATED NOTE DUE 2010 
  
 This Note is one of a duly authorized issue of Notes of the Company, designated as its 1% Convertible Subordinated Notes due
2010 (the “Notes”), limited to the aggregate principal amount of $65,000,000, or up to $75,000,000 if the Initial Purchaser’s option to purchase additional Notes is exercised, all issued or to be issued under and pursuant to an
Indenture dated as of June 30, 2004 (the “Indenture”), between the Company and J.P. Morgan Trust Company, National Association, as trustee (the “Trustee”), to which Indenture and all indentures supplemental thereto
reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders of the Notes. 
  
 In case an Event of Default (as defined in the Indenture) shall have occurred and be continuing, the principal of, premium,
if any, and accrued interest (including Liquidated Damages (as defined in the Registration Rights Agreement), if any) on all Notes may be declared, by either the Trustee or the holders of not less than 25% in aggregate principal amount of the Notes
then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture. 
  
 The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than a
majority in aggregate principal amount of the Notes at the time outstanding, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture
or modifying in any manner the rights of the holders of the Notes; provided, however, that no such supplemental indenture shall (i) extend the fixed maturity of any Note, or reduce the rate or extend the time of payment of interest
thereon, or reduce the principal amount thereof or premium, if any, thereon, or reduce any amount payable upon purchase thereof, or impair the right of any Noteholder to institute suit for the payment thereof, or make the principal thereof or
interest or premium, if any, thereon payable in any coin or currency other than that provided in the Notes, or modify the provisions of the Indenture with respect to the subordination of the Notes in a manner adverse to the Noteholders in any
material respect, or change the obligation of the Company to purchase any Note upon the happening of a Fundamental Change (as defined in the Indenture) in a manner adverse to the holder of the Notes, or impair the right to convert the Notes into
Common Stock subject to the terms set forth in the Indenture, including Sections 15.02, 15.06 and 15.07 thereof, in each case without the consent of the holder of each Note so affected or (ii) reduce the aforesaid percentage of Notes, the holders of
which are 
  

 A-7 

 required to consent to any such supplemental indenture, or reduce the percentage of Notes, the holders of which are
required to constitute a quorum at a meeting of Noteholders under Section 10.05 of the Indenture, without the consent of the holders of all Notes then outstanding. Subject to the provisions of the Indenture, the holders of a majority in aggregate
principal amount of the Notes at the time outstanding may on behalf of the holders of all of the Notes waive any past default or Event of Default under the Indenture and its consequences except a default in the payment of interest (including
Liquidated Damages, if any) or any premium on, or the principal of, any of the Notes, or a failure by the Company to convert any Notes into Common Stock of the Company, or a default in the payment of the purchase price pursuant to Article 3 of the
Indenture, or a default in respect of a covenant or provisions of the Indenture which under Article 11 of the Indenture cannot be modified without the consent of the holders of each or all Notes then outstanding or affected thereby. Any such consent
or waiver by the holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such holder and upon all future holders and owners of this Note and any Notes which may be issued in exchange or substitution
hereof, irrespective of whether or not any notation thereof is made upon this Note or such other Notes. 
  
 The indebtedness evidenced by the Notes is, to the extent and in the manner provided in the Indenture, expressly subordinated and subject in right of
payment to the prior payment in full of all Senior Indebtedness of the Company, whether outstanding at the date of the Indenture or thereafter incurred, and this Note is issued subject to the provisions of the Indenture with respect to such
subordination. Each holder of this Note, by accepting the same, agrees to and shall be bound by such provisions and authorizes the Trustee on its behalf to take such action as may be necessary or appropriate to effectuate the subordination so
provided and appoints the Trustee his attorney-in-fact for such purpose. 
  
 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 (including Liquidated Damages, if any) on this Note at the place, at the respective times, at the rate and in the coin or currency herein prescribed. 
  
 Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. 
  
 The Notes are issuable in fully registered form, without coupons, in
denominations of $1,000 principal amount and any integral multiple of $1,000. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, without payment of any
service charge but with payment of a sum sufficient to cover any tax, 
  

 A-8 

 assessment or other governmental charge that may be imposed in connection with any registration or exchange of Notes,
Notes may be exchanged for a like aggregate principal amount of Notes of any other authorized denominations. 
  
 The Notes are not subject to redemption (except to the extent that a purchase following a Fundamental Change may be deemed a redemption) by the Company or
through the operation of any sinking fund. 
  
 If there shall
occur a Fundamental Change at any time prior to maturity of the Notes, then each Noteholder shall have the right, at such holder’s option, to require the Company to purchase all of such holder’s Notes, or any portion thereof that is an
integral multiple of $1,000 principal amount, for cash, on the date (the “Purchase Date”) that is 30 days after the date of the Company Notice (as defined in Section 3.02(b) of the Indenture) of such Fundamental Change (or, if such
30th day is not a Business Day, the next succeeding Business Day) at a purchase price equal to 100% of the principal amount thereof, plus accrued but unpaid interest, and Liquidated Damages, if any, to (but excluding) the Purchase Date;;
provided, however, that, if such Purchase Date is a June 30 or December 30, then the interest payable on such date shall be paid to the holder of record of the Notes as of the close of business on the preceding June 15 or December 15,
respectively. If there shall have occurred a Fundamental Change and at least sixty percent (60%) of the consideration for the Common Stock in the transaction or transactions constituting the Fundamental Change consists of cash (a “Cash
Buy-Out”), the Company will pay a Make-Whole Premium to the holders of Notes in addition to the purchase price. If a holder surrenders its Notes (or any portion thereof) for conversion after receipt of a Company Notice and prior to the
Purchase Date, and the Fundamental Change related to the Company Notice constitutes a Cash Buy-Out, the Company will pay a Make-Whole Premium to such holder, in addition to the shares of Common Stock deliverable upon conversion of the Notes.

  
 The “Make-Whole Premium” per Note will equal (a) the
average of the Closing Trading Prices of a Note for the five Trading Days immediately prior to the Public Announcement Date of the Cash Buy-Out, less (b) the greater of (i) $1,000 or (ii) the product of (x) the average Closing Prices of the Common
Stock for the five Trading Days immediately prior to the Public Announcement Date of the Cash Buy-Out and (y) the applicable Conversion Rate; and will be payable in cash. The Make-Whole Premium, if any, will not be less than zero. 
  
 The Company shall mail to all holders of record of the Notes a notice of the
occurrence of a Fundamental Change and of the purchase right arising as a result thereof on or before the 10th day after the occurrence of such Fundamental Change. For a Note to be so purchased at the option of the holder, the Company must receive
at the office or agency of the Company maintained for that purpose 
  

 A-9 

 in accordance with the terms of the Indenture, such Note with the form entitled “Option to Elect Repayment Upon a
Fundamental Change” on the reverse thereof duly completed, together with such Note, duly endorsed for transfer, on or before the 30th day after the date of such notice of a Fundamental Change (or if such 30th day is not a Business Day, the
immediately succeeding Business Day). 
  
 Subject to the
provisions of the Indenture, the holder hereof has the right, to the extent that a Conversion Termination has not occurred, at its option, at any time through the close of business on the final maturity date of the Notes, to convert each $1,000
principal amount of the Notes into 77.8743 shares of the Company’s Common Stock (the “Conversion Rate”), as such shares shall be constituted at the date of conversion and subject to adjustment from time to time as provided in
the Indenture, upon surrender of this Note, duly endorsed, together with a conversion notice as provided in the Indenture (the form entitled “Conversion Notice” on the reverse hereof), to the Company at the office or agency of the
Company maintained for that purpose in accordance with the terms of the Indenture, including the Corporate Trust Office (as defined in the Indenture), and, unless the shares issuable on conversion are to be issued in the same name as this Note, duly
endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the holder or by his duly authorized attorney. No adjustment in respect of interest on any Note converted or dividends on any shares issued
upon conversion of such Note will be made upon any conversion except as set forth in the next sentence or except as provided in the Indenture. If this Note (or portion hereof) is surrendered for conversion during the period from the close of
business on any record date for the payment of interest to the close of business on the Business Day preceding the following interest payment date, this Note (or portion hereof being converted) must be accompanied by an amount, in New York Clearing
House funds or other funds acceptable to the Company, equal to the interest payable on such interest payment date on the principal amount being converted; provided, however, that no such payment shall be required if there shall exist at the
time of conversion a default in the payment of interest on the Notes or if, in the case of the June 30, 2006 interest payment, the Company has elected to terminate the Conversion Right pursuant to Section 15.02 of the Indenture and such Note is
surrendered for conversion during the five day period prior to June 30, 2006. No fractional shares will be issued upon any conversion, but an adjustment and payment in cash will be made, as provided in the Indenture, in respect of any fraction of a
share which would otherwise be issuable upon the surrender of any Note or Notes for conversion. A Note in respect of which a holder is exercising its right to require purchase upon a Fundamental Change may be converted only if such holder withdraws
its election to exercise such right in accordance with the terms of the Indenture. 
  

 A-10 

 The Company may terminate the right of holders to convert their Notes into Common Stock (the
“Conversion Right”), at any time on or after June 30, 2006, if the Closing Price of the Common Stock has exceeded 140% of the Conversion Price then in effect for at least 20 Trading Days within a period of 30 consecutive Trading
Days (a “Conversion Termination Trigger Event”). If the Company elects to terminate the Conversion Right upon a Conversion Termination Trigger Event, then the Company will be required to deliver an irrevocable notice to record
holders of Notes within five Trading Days of the date of the applicable Conversion Termination Trigger Event (the “Conversion Termination Notice,” and the date of such Conversion Termination Notice, the “Conversion
Termination Notice Date”). Holders may convert their Notes at any time on or prior to the twentieth (20th)
day following the Conversion Termination Notice Date (the “Conversion Termination Date”). The Conversion Rights of all holders shall terminate after the Conversion Termination Date (a “Conversion Termination”), and
thereafter the holders shall have no rights to convert and receive shares of Common Stock under the Notes or this Indenture. 
  
 The Company will not be required to make any interest payment on an interest payment date with respect to any Note that is surrendered for conversion
after the Conversion Termination Notice Date and prior to the Conversion Termination Date on a Conversion Date that is between a record date for the payment of interest to the next succeeding interest payment date; provided, however, in the
case of the June 30, 2006 interest payment, if the Company has elected to terminate the Conversion Right, the Company will be required to make such June 30, 2006 interest payment with respect to Notes surrendered for conversion on a Conversion Date
that is during the five day period prior to the June 30, 2006. 
  
 Upon due presentment for registration of transfer of this Note at an office or agency of the Company maintained for that purpose in accordance with the terms of the Indenture, a new Note or Notes of authorized denominations for an equal
aggregate principal amount will be issued to the transferee in exchange thereof, subject to the limitations provided in the Indenture, without charge except for any tax, assessment or other governmental charge imposed in connection therewith.

  
 The Company, the Trustee, any paying agent, any conversion
agent and any Note registrar may deem and treat the registered holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing hereon made by anyone other
than the Company or any Note registrar) for the purpose of receiving payment hereof, or on account hereof, for the conversion hereof and for all other purposes, and neither the Company nor the Trustee nor any paying agent nor other conversion

  

 A-11 

 agent nor any Note registrar shall be affected by any notice to the contrary. All payments made to or upon the order of
such registered holder shall, to the extent of the sum or sums paid, satisfy and discharge liability for monies payable on this Note. 
  
 No recourse for the payment of the principal of or any premium or interest on this Note, or for any claim based hereon or otherwise in respect hereof, and
no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any supplemental indenture or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator,
stockholder, employee, agent, officer or director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any
constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released. 
  
 This Note shall be deemed to be a contract made under the laws of New York,
and for all purposes shall be construed in accordance with the laws of New York. 
  
 Terms used in this Note (and not otherwise defined herein) that are defined in the Indenture are used herein as therein defined.
