 THE NOTES 
 SECTION 2.01. Title and Terms; Payments. There is hereby established a series of Securities designated the “4.50% Convertible Senior Notes due 2015” initially limited in aggregate principal amount to $86,250,000, which
amount shall be as set forth in a Company Order for the authentication and delivery of Notes pursuant to Section 3.03 of the Original Indenture. 
 The principal amount of Notes then Outstanding shall be payable at the Stated Maturity. Interest on the Notes shall accrue at a rate of 4.50% per annum, from October 28, 2009 or from the most
recent date on which interest has been paid or duly provided for, until the principal thereof is paid or made available for payment. Interest shall be payable on each Interest Payment Date, beginning on May 1, 2010, to the Person in whose name
a Note is registered on the Security Register at the close of business on the Regular Record Date immediately preceding the applicable Interest Payment Date. 
 The Company may, without the consent of the Holders of the Notes, hereafter issue additional Notes (“Additional Notes”) under the Indenture with the same terms and with the

  

 11 








 
same CUSIP numbers as the Notes issued on the date of this Supplemental Indenture (the “Initial Notes”) in an unlimited aggregate principal amount; provided that such
Additional Notes must be part of the same issue as the Initial Notes for federal income tax purposes. Any such Additional Notes shall constitute a single series together with the Initial Notes for all purposes hereunder, including, without
limitation, for purposes of any waivers, supplements or amendments to the Indenture requiring the approval of Holders of the Notes and any offers to purchase the Notes. 
 The Form of Note shall be substantially as set forth in Schedule B and the Form of Conversion Notice, the Form of Fundamental Change Repurchase Notice and the Form of Assignment and Transfer shall be
substantially as set forth in Attachments 1, 2 and 3, respectively, to Schedule B, each of which is incorporated into and shall be deemed a part of this Supplemental Indenture, and in each case with such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by the Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with the rules of any
securities exchange or as may, consistently herewith, be determined to be necessary or appropriate by the Officers of the Company executing such Notes, as evidenced by their execution of the Notes. 
 The Company shall pay the principal of and interest on any Global Note in immediately available funds to the Depositary or its nominee, as
the case may be, as the registered Holder of such Global Note. The Company shall pay the principal of and interest on any Physical Notes at the office or agency designated by the Company for that purpose by check mailed to the Holders of these
Notes, unless a Holder timely requests to have such amounts paid by wire transfer in accordance with the final three sentences of this paragraph, in which case the Company shall instead pay such principal of and interest on any Physical Notes by
wire transfer in accordance with the transfer instructions provided in such request. The Company has initially designated the Trustee as its Paying Agent and Security Registrar in respect of the Notes and its agency in New York, New York as a place
where Notes may be presented for payment or for registration of transfer. The Company may, however, change the Paying Agent or Security Registrar for the Notes without prior notice to the Holders thereof, and the Company may act as Paying Agent or
Security Registrar for the Notes. Payments on any Physical Notes having an aggregate principal amount of more than $5,000,000 shall be payable, if the Holder of such Physical Notes so requests in accordance with the two immediately succeeding
sentences, by wire transfer of immediately available funds to an account specified by the Holder within the United States. To request payment by wire transfer, the Holder must give appropriate transfer instructions to the Trustee or other Paying
Agent (if not the Trustee) at least 15 Business Days before the requested wire payment is due and, in the case of any interest payments, the instructions must be given by the Person who is shown on the Trustee’s records as the Holder of the
Physical Note on the applicable Regular Record Date. All applications for payment by wire transfer shall be made no later than the applicable Regular Record Date and shall remain in effect unless and until new instructions are given in the manner
described in the immediately preceding sentence. 
 SECTION 2.02. Book-Entry Provisions for Global Notes. The Notes
initially shall be issued in the form of one or more Global Notes without interest coupons (i) registered in the name of Cede & Co., as nominee of the Depositary and (ii) delivered to the Trustee as custodian for the Depositary.

  

 12 








 SECTION 2.03. Reporting Requirement. For purposes of the Notes, the period
within which the Company is required to perform its delivery obligation as set forth in Section 7.04 of the Original Indenture, shall be reduced from 30 days to 15 days. 
 SECTION 2.04. Repurchase and Cancellation. To the extent permitted by law, the Company may repurchase Notes in open-market
purchases or negotiated transactions without giving prior notice to Holders. The Company shall surrender any Notes repurchased by the Company to the Trustee for cancellation in accordance with Section 3.09 of the Original Indenture and any such
Notes repurchased by the Company shall be retired and no longer Outstanding. Any Notes surrendered for cancellation by the Company shall not be reissued or resold. 
 ARTICLE 3 
 FUNDAMENTAL CHANGES AND REPURCHASES THEREUPON 

SECTION 3.01. Repurchase at Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any time prior
to the Stated Maturity, then each Holder of Notes shall have the right, at such Holder’s option, to require the Company to repurchase for cash any or all of such Holder’s Notes, or any portion of the principal amount thereof, that is equal
to $1,000 or an integral multiple of $1,000, on a date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 calendar days or more than 45 calendar days following the date of the Fundamental
Change Company Notice, at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase
Price”), unless the Fundamental Change Repurchase Date is after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of
accrued and unpaid interest on the Interest Payment Date to the Holders of record on such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of the Notes to be repurchased pursuant to this
Article 3. 
 Purchases of Notes under this Section 3.01 shall be made, at the option of the Holder thereof, upon:

 (i) delivery to the Trustee (or other Paying Agent appointed by the Company) by a Holder, on or before the
close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, subject to extension to comply with applicable law, of a duly completed notice (the “Fundamental Change Repurchase Notice”) in the
form set forth in Attachment 2 to the Form of Note attached hereto as Schedule B specifying: 
 (A) in the case
of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase; 
 (B) the portion of the
principal amount of Notes to be repurchased, which must be $1,000 or a multiple thereof; and 
  

 13 








 (C) that the Notes are to be repurchased by the Company pursuant to the
applicable provisions of the Notes and the Indenture; and 
 (ii) delivery or book-entry transfer of the Notes to
the Trustee (or other Paying Agent appointed by the Company) (together with all necessary endorsements) at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, subject to extension
to comply with applicable law, at the applicable Corporate Trust Office of the Trustee (or other Paying Agent appointed by the Company), such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor;
provided that (x) such Fundamental Change Repurchase Price shall be so paid pursuant to this Section 3.01 only if the Notes so delivered to the Trustee (or other Paying Agent appointed by the Company) shall conform in all respects
to the description thereof in the related Fundamental Change Repurchase Notice and (y) in the case of Global Notes, the Fundamental Change Repurchase Notice must comply with appropriate procedures of the Depositary. 
 Any repurchase by the Company contemplated pursuant to the provisions of this Section 3.01 shall be consummated by the delivery of the
consideration to be received by the Holder on the later of (i) the Fundamental Change Repurchase Date or (ii) the time of the book-entry transfer or delivery of the Notes (as specified in Section 3.02 hereof). 
 Notwithstanding anything herein to the contrary, any Holder delivering to the Trustee (or other Paying Agent appointed by the Company) the
Fundamental Change Repurchase Notice contemplated by this Section 3.01 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately
preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Trustee (or other Paying Agent appointed by the Company) in accordance with Section 3.03 below. 
 The Trustee (or other Paying Agent appointed by the Company) shall promptly notify the Company of the receipt by it of any Fundamental
Change Repurchase Notice or written notice of withdrawal thereof. 
 (b) On or before the 20th calendar day after the occurrence
of a Fundamental Change, the Company shall provide to all Holders of the Notes and the Trustee and Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the “Fundamental Change Company Notice”) of the
occurrence of such Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. Such notice shall be sent by first class mail or in the case of Global Notes, in accordance with the procedures of the
Depositary for providing notices. Simultaneously with providing such Fundamental Change Company Notice, the Company shall publish a notice containing the information included therein on the Company’s website or through such other public medium
as the Company may use at such time. 
 Each Fundamental Change Company Notice shall specify: 
 (i) the events causing a Fundamental Change; 
 (ii) the date of the Fundamental Change; 
  

 14 








 (iii) the last date on which a Holder of Notes may exercise the repurchase
right pursuant to this Article 3; 
 (iv) the Fundamental Change Repurchase Price; 
 (v) the Fundamental Change Repurchase Date; 
 (vi) the name and address of the Paying Agent and the Conversion Agent, if applicable; 
 (vii) if applicable, the Applicable Conversion Rate and any adjustments to the Applicable Conversion Rate; 
 (viii) if applicable, that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a
Holder may be converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with Section 3.03; and 
 (ix) the procedures that Holders must follow to require the Company to repurchase their Notes. 
 No failure of the Company to give the foregoing notices and no defect therein shall limit the Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes
pursuant to this Section 3.01. 
 (c) There shall be no repurchase of any Notes pursuant to this Section 3.01 if the
principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change
Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any Notes (i) with respect to which a Fundamental Change Repurchase Notice has been withdrawn in compliance with this
Supplemental Indenture, or (ii) held by it during the continuance of an acceleration of the Notes (other than an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such
Notes) in which case, upon such return, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 
 SECTION 3.02. Effect of Fundamental Change Repurchase Notice. Upon receipt by the Paying Agent of the Fundamental Change Repurchase Notice specified in Section 3.01(a), the Holder of the
Note in respect of which such Fundamental Change Repurchase Notice was given shall (unless such Fundamental Change Repurchase Notice is withdrawn in accordance with Section 3.03) thereafter be entitled to receive solely the Fundamental Change
Repurchase Price in cash with respect to such Note. Such Fundamental Change Repurchase Price shall be paid to such Holder on the later of (x) the Fundamental Change Repurchase Date with respect to such Note (provided the conditions in
Section 3.01(a) have been satisfied) and (y) the time of book-entry transfer or delivery of such Note to the Paying Agent by the Holder thereof in the manner required by Section 3.01. 
  

 15 








 SECTION 3.03. Withdrawal of Fundamental Change Repurchase Notice. (a) A
Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with the Fundamental Change Company Notice at any time prior to the close of business
on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying: 
 (i) the
principal amount of the Notes with respect to which such notice of withdrawal is being submitted; 
 (ii) in the
case of Physical Notes, the certificate numbers of the withdrawn Notes; and 
 (iii) the principal amount of such
Notes that remains subject to the original Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; 
 provided, however, that in the case of Global Notes, the notice must comply with appropriate procedures of the Depositary. 
 The Paying Agent will promptly return to the respective Holders thereof any Physical Notes with respect to which a Fundamental Change
Repurchase Notice has been withdrawn in compliance with the provisions of this Section 3.03. 
 SECTION 3.04.
Deposit of Fundamental Change Repurchase Price. Prior to 11:00 a.m. (New York City time) on the Fundamental Change Repurchase Date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a Subsidiary or an
Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 10.03 of the Original Indenture) an amount of money (in immediately available funds if deposited on such Business Day)
sufficient to pay the Fundamental Change Repurchase Price of and, if the Fundamental Change Repurchase Date occurs after a Regular Record Date and on or prior to the Interest Payment Date to which such Regular Record Date relates, accrued and unpaid
interest on, all the Notes or portions thereof that are to be repurchased as of the Fundamental Change Repurchase Date. The Company shall promptly notify the Trustee in writing of the amount of any deposits of cash made pursuant to this
Section 3.04. If the Paying Agent holds cash sufficient to pay the Fundamental Change Repurchase Price of, plus any such interest on, the Notes for which a Fundamental Change Repurchase Notice has been submitted and not withdrawn in accordance
with this Supplemental Indenture as of 11:00 a.m. New York City time on the Fundamental Change Repurchase Date, then as of such Fundamental Change Repurchase Date, (a) such Notes will cease to be Outstanding and interest will cease to accrue
thereon (whether or not book-entry transfer of such Notes is made or such Notes are delivered to the Paying Agent) and (b) all other rights of the Holders in respect thereof will terminate (other than the right to receive the Fundamental Change
Repurchase Price and, if the Fundamental Change Repurchase Date occurs after a Regular Record Date and on or prior to the Interest Payment Date to which such Regular Record Date relates, accrued and unpaid interest on such Notes, in the case of the
Fundamental Change Repurchase Price, upon delivery or book-entry transfer of such Notes). 
  

 16 








 SECTION 3.05. Notes Repurchased in Whole or in Part. Any Note that is to be
repurchased, whether in whole or in part, shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires in the case of Physical Notes, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note,
without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not
repurchased. 
 SECTION 3.06. Covenant to Comply With Applicable Laws Upon Repurchase of Notes. In connection with
any repurchase of Notes under Section 3.01, the Company shall, in each case if required, (i) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable, (ii) file a Schedule
TO or any other required schedule under the Exchange Act and (iii) otherwise comply with all federal and state securities laws, in each case, so as to permit the rights and obligations under Section 3.01 to be exercised in the time and in

Agent shall return to the Company any cash that remains unclaimed, together with interest, if any, thereon, held by them for the payment of the Fundamental Change Repurchase Price; provided that to the extent that the aggregate amount of cash
deposited by the Company pursuant to Section 3.04 exceeds the aggregate Fundamental Change Repurchase Price of, and any accrued and unpaid interest on, the Notes or portions thereof that the Company is obligated to repurchase as of the
Fundamental Change Repurchase Date, then as soon as practicable following the Fundamental Change Repurchase Date, the Trustee or the Paying Agent, as the case may be, shall return any such excess to the Company. 
 ARTICLE 4 
 CONVERSION 
 SECTION 4.01. Right to Convert. 
 (a) Subject to and upon compliance with the provisions of this Article 4, each Holder of Notes shall have the right, at such Holder’s
option, to convert the principal amount of any such Notes, or any portion of such principal amount that is $1,000 or an integral multiple thereof, at the Applicable Conversion Rate (subject to the settlement provisions set forth in
Section 4.03, the “Conversion Obligation”), (x) prior to the close of business on the Business Day immediately preceding February 1, 2015, but only upon the satisfaction of one or more of the conditions set forth in
clauses (i) through (v) below and only during the periods described therein and (y) on or after February 1, 2015 through the close of business on the Business Day immediately preceding the Stated Maturity irrespective of the
conditions set forth below: 
 (i) Prior to the close of business on the Business Day immediately preceding
February 1, 2015, a Holder may surrender all or a portion of its Notes for conversion during any fiscal quarter (and only during such fiscal quarter) commencing after January 1, 2010, if the Last Reported Sale Price of the Common Stock for
at least 20 Trading

  

 17 








 
Days during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding fiscal quarter is greater than or equal to 130% of the applicable Conversion
Price in effect on each such Trading Day. 
 (ii) Prior to the close of business on the Business Day immediately
preceding February 1, 2015, a Holder of Notes may surrender its Notes for conversion during the five Business-Day period after any five consecutive Trading-Day period (the “Measurement Period”) in which the Trading Price per
$1,000 principal amount of Notes, as determined following a request by a Holder of the Notes in accordance with the procedures set forth in this Section 4.01(a)(ii), for each Trading Day of such Measurement Period was less than 98% of the
product of the Last Reported Sale Price of the Common Stock and the Applicable Conversion Rate. The Bid Solicitation Agent shall have no obligation to determine the Trading Price of the Notes in accordance with this Section 4.01(a)(ii) unless
requested by the Company, and the Company shall have no obligation to make such request unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than 98% of the product
of the Last Reported Sale Price of the Common Stock and the Applicable Conversion Rate. At the time of receiving such evidence, the Company shall instruct the Bid Solicitation Agent to determine the Trading Price of the Notes beginning on the next
Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Applicable Conversion Rate. If the
Trading Price condition has been met the Company shall so notify the Holders of the Notes in the manner provided in Section 1.07 of the Original Indenture, the Trustee and the Conversion Agent. If, at any time after the Trading Price condition
has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Applicable Conversion Rate for such date, the Company shall so notify the
Holders of the Notes in the manner provided in Section 1.07 of the Original Indenture, the Trustee and the Conversion Agent. 
 (iii) If, prior to the close of business on the Business Day immediately preceding February 1, 2015, the Company elects to: 
 (A) issue to all or substantially all holders of Common Stock certain rights (in the case of rights issued under a
shareholder rights agreement, only following the distribution of separate certificates evidencing such rights) entitling them to purchase, for a period of not more than 60 calendar days after the announcement date of such issuance to subscribe for
or purchase, shares of Common Stock at a price per share less than the average of the Last Reported Sale Prices of Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of
such issuance; or 
 (B) distribute to all or substantially all holders of Common Stock the Company’s
assets, debt securities or rights to purchase securities of the Company, which distribution has a per share Fair Market Value, as reasonably determined

  

 18 








 
by the Company’s Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the date of announcement for such
distribution, 
 then, in either case, the Company shall notify the Holders of the Notes, in the manner provided in
Section 1.07 of the Original Indenture, at least 30 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. Once the Company has given such notice, Holders may surrender their Notes for conversion at any time
until the earlier of (x) the close of business on the Business Day immediately prior to such Ex-Dividend Date and (y) the Company’s announcement that such issuance or distribution will not take place, even if the Notes are not
otherwise convertible at such time. 
 (iv) If, prior to the close of business on the Business Day immediately
preceding February 1, 2015, a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Article
3 hereof, or if the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of the Company’s assets, pursuant to which the Common Stock would be converted into cash, securities or
other assets, Holders may surrender Notes for conversion at any time from or after the date that is 30 Scheduled Trading Days prior to the anticipated effective date of the transaction until 35 Trading Days after the actual effective date of such
transaction or, if such transaction also constitutes a Fundamental Change, until the close of business on the Business Day immediately preceding the related Fundamental Change Repurchase Date. The Company shall notify Holders and the Trustee, in the
manner provided in Section 1.07 of the Original Indenture as promptly as practicable following the date the Company publicly announces such transaction, but in no event less than 30 Scheduled Trading Days prior to the anticipated effective date
of such transaction. 
 (v) If the Company calls the Notes for redemption, Holders may convert their Notes during
the period from, and including, the date of the Redemption Notice to the close of business on the Business Day prior to the Redemption Date, even if the Notes are not otherwise convertible at such time, after which time the Holder’s right to
convert shall expire (unless the Company defaults in the payment of the Redemption Price, in which case a Holder of Notes may convert such Notes until the Redemption Price has been paid or duly provided for). 
 (b) Notes may not be converted after the close of business on the Business Day immediately preceding May 1, 2015. 
 SECTION 4.02. Conversion Procedures. (a) Each Note shall be convertible at the office of the Conversion Agent and, in the case
of a Global Note, in accordance with the procedures of the Depositary. 
 (b) In order to exercise the conversion privilege with
respect to a beneficial interest in a Global Note, the Holder must complete the appropriate instruction form for conversion

  

 19 








 
pursuant to the Depositary’s book-entry conversion program, furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or Conversion Agent, and pay the
funds, if any, required by Section 4.03(e) and any transfer taxes, if required, pursuant to Section 4.08, and the Trustee or Conversion Agent must be informed of the conversion in accordance with the customary practice of the Depositary.
In order to exercise the conversion privilege with respect to any Physical Notes, the Holder of any such Notes to be converted, in whole or in part, shall: 
 (i) complete and manually sign the conversion notice provided on the back of the Note (the “Conversion Notice”) or a facsimile of the Conversion Notice; 
 (ii) deliver the Conversion Notice, which is irrevocable, and the Note to the Conversion Agent; 
 (iii) if required, furnish appropriate endorsements and transfer documents, 
 (iv) if required, pay all transfer or similar taxes as set forth in Section 4.08; and 
 (v) if required, make any payment required under Section 4.03(e). 
 The date on which the Holder satisfies all of the applicable requirements set forth above shall be the “Conversion Date.”
The Trustee will, as promptly as possible, and in any event within two (2) Business Days, provide the Company with notice of any conversion exercises by Holders of which a Responsible Officer becomes aware. 
 (c) Each Conversion Notice shall state the name or names (with address or addresses) in which any certificate or certificates for shares of
Common Stock which shall be issuable on such conversion shall be issued. All such Notes surrendered for conversion shall, unless the shares of Common Stock issuable on conversion are to be issued in the same name as the registration of such Notes,
be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or its duly authorized attorney. 
 (d) In case any Notes of a denomination greater than $1,000 shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Notes
so surrendered, without charge to such Holder, new Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Notes. 
 Each conversion shall be deemed to have been effected as to any such Notes (or portion thereof) surrendered for conversion on the relevant
Conversion Date; provided, however, that the Person in whose name any certificate or certificates for shares of Common Stock shall be issuable upon such conversion shall become the holder of record of such shares of Common Stock as of the
close of business on the relevant Conversion Date (in the case of Physical Settlement) or the last Trading Day of the relevant Observation Period (in the case of Combination Settlement), as the case may be. 
 (e) Upon the conversion of a beneficial interest in Global Notes, the Trustee (or other Conversion Agent appointed by the Company) shall
make a notation on such Global Notes as to

  

 20 








 
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. 
 (f) Notwithstanding the foregoing, a Note in respect of which a Holder has delivered a Fundamental Change Repurchase
Notice exercising such Holder’s option to require the Company to repurchase such Note may be converted only if such Fundamental Change Repurchase Notice is withdrawn in accordance with Article 3 hereof prior to the close of business on the
Business Day prior to the relevant Fundamental Change Repurchase Date. 
 SECTION 4.03. Settlement Upon Conversion.
(a) Subject to Section 4.02 and Section 4.06, upon any conversion of any Note, the Company may choose to pay or deliver, as the case may be, (i) solely cash (“Cash Settlement”), (ii) solely shares of its Common
Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock (“Physical Settlement”) or (iii) a combination of cash and shares of its Common Stock, together with cash, if applicable, in lieu of any
fractional share of Common Stock (“Combination Settlement”). Subject to Section 4.03(h), the Company shall pay or deliver, as the case may be, to converting Holders, in respect of each $1,000 principal amount of Notes being
converted, the consideration due upon conversion as described below in Section 4.03(b) on (i) the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, and (ii) on the third
Business Day immediately following the last Trading Day of the relevant Observation Period, in the case of any other Settlement Method. 
 (b) The amount of cash and/or the number of shares of Common Stock due upon conversion of the Notes shall be computed as follows: 
 (i) if the Company elects to satisfy its Conversion Obligation by Physical Settlement, the Company shall deliver to the
converting Holder a number of shares of Common Stock equal to the product of (x) the aggregate principal amount of Notes to be converted, divided by $1,000 and (y) the Applicable Conversion Rate; 
 (ii) if the Company elects to satisfy its Conversion Obligation by Cash Settlement, the Company shall pay to the converting
Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 20 consecutive Trading Days during the relevant Observation Period; and 
 (iii) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation by Combination Settlement,
the Company shall pay or deliver, as the case may be, to the converting Holder in respect of each $1,000 principal amount of Notes being converted, an amount of cash and shares of Common Stock equal to the sum of the Daily Settlement Amounts for
each of the 20 consecutive Trading Days during the relevant Observation Period. 
 (c) The same Settlement Method shall be used
in each of the following cases: 
 (i) all conversions occurring on or after February 1, 2015, and all
conversions occurring on or after the date of issuance of a Redemption Notice and prior to the related Redemption Date; and 
  

 21 








 (ii) all conversions occurring on the same Conversion Date prior to
February 1, 2015 (except, if the Company elects to redeem the Notes, during the period after the date of issuance of a Redemption Notice and prior to the related Redemption Date). 
 provided however, that except as described in (i) and (ii) above, the Company shall not have any obligation to elect the
same Settlement Method with respect to conversions occurring on different Trading Days. If the Company elects a Settlement Method, the Company will inform Holders so converting through the Trustee of such Settlement Method selected no later than the
second Trading Day immediately following the related Conversion Date (or, in the case of any Conversion Date occurring on or after (x) the date of issuance of a Redemption Notice and prior to the related Redemption Date, in such Redemption
Notice or (y) February 1, 2015, no later than February 1, 2015). If the Company does not timely elect a Settlement Method, it shall no longer have the right to elect Cash Settlement or Physical Settlement, and it shall be deemed to
have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount shall be equal to $1,000. If the Company elects Combination Settlement, but does not indicate a Specified Dollar Amount, the Specified
Dollar Amount shall be deemed to be $1,000. It is the Company’s current intent and policy to settle conversion through Combination Settlement with a Specified Dollar Amount of $1,000. 
 (d) Subject to clause (e) below, upon conversion, Holders shall not receive any separate cash payment for accrued and unpaid interest,
if any. 
 (e) If Notes are converted after the close of business on a Regular Record Date for the payment of interest, Holders
of such Notes at the close of business on such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the
period from the close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date, must be accompanied by funds equal to the full amount of interest, if any, payable on the Notes so converted;
provided that no such payment need be made (i) for conversions following the Regular Record Date immediately preceding the Stated Maturity; (ii) if the Company has specified a Redemption Date that is after a Regular Record Date and
on or prior to the Business Day immediately following the corresponding Interest Payment Date; (iii) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day
immediately following the corresponding Interest Payment Date or; (iv) to the extent of any Defaulted Interest, if any overdue interest exists at the time of conversion with respect to such Note. 
 (f) The Company shall not issue fractional shares of Common Stock upon conversion of Notes. If multiple Notes shall be surrendered for
conversion at one time by the same Holder, the number of full shares of Common Stock which shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent
permitted hereby) so surrendered. If any fractional share of Common Stock

  

 22 








 
would be issuable upon the conversion of any Notes, the Company shall make payment therefor in cash in lieu of fractional shares of Common Stock based on the Daily VWAP of the Common Stock on the
relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP on the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). 
 (g) Solely for purposes of determining the consideration due upon conversion under this Section 4.03, and notwithstanding the
definition of “Trading Day” contained in Section 1.01, “Trading Day” means a day on which (i) there is no Market Disruption Event and (ii) trading in the Common Stock generally occurs on The NASDAQ Global
Select Market or, if the Common Stock is not then listed on The NASDAQ Global Select Market, on the principal other United States national or regional securities exchange on which the Common Stock is then listed or, if the Common Stock is not then
listed on a United States national or regional securities exchange, on the principal other market on which the Common Stock is then traded. If the Common Stock (or other security for which a Daily VWAP must be determined) is not so listed or quoted,
“Trading Day” means a Business Day. 
 (h) Upon surrender of Notes for conversion in connection with a Make-Whole
Fundamental Change, the Company shall, at its option, satisfy its Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with this Section 4.03. However, if the consideration paid for the Common Stock
in any Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the amount of
cash due upon conversion of the Notes shall be calculated based solely on the Stock Price for such Make-Whole Fundamental Change (in lieu of the Daily VWAP), and the relevant Conversion Obligation per $1,000 principal amount of Notes shall be equal
to the Applicable Conversion Rate (including any adjustment as described in Section 4.06 hereof), multiplied by such Stock Price. In such event, the consideration due upon conversion shall be determined and paid to Holders solely in cash on
the third Business Day following the relevant Conversion Date. 
 SECTION 4.04. Adjustment of Conversion Rate. The
Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustment to the Conversion Rate if Holders of Notes participate (other than in the case of a share
split or share combination), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 4.04 without having to convert their Notes as
if such Holders held a number of shares of Common Stock equal to the Applicable Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder. 
 (a) If the Company exclusively issues shares of its Common Stock as a dividend or distribution on shares of Common Stock, or if the Company
effects a share split or share combination, then the Conversion Rate shall be adjusted based on the following formula: 
  

											
	CR1	  	=	  	CR0	  	x	  	   OS0  
	  	
	  	  	  	  	OS1	  	

  

 23 








 where, 
  

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


 Any adjustment made under this Section 4.04(a) shall become effective immediately after
the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination. If any dividend or distribution of the type described in this
clause (a) is declared but not so paid or made, or any share split or combination of the type described in this clause (a) is announced but the outstanding shares of Common Stock are not split or combined, as the case may be, the
Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, or not to split or combine the outstanding shares of Common Stock, as the case may be, to the
Conversion Rate that would then be in effect if such dividend, distribution, share split or share combination had not been declared or announced. 
 (b) If the Company issues to all or substantially all holders of the Common Stock any rights, options or warrants entitling them for a period of not more than 60 calendar days after the announcement date
of such issuance to subscribe for or purchase shares of Common Stock, at a price per share less than the average of the Last Reported Sale Prices of Common Stock for the 10 consecutive Trading-Day period ending on the Trading Day immediately
preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on the following formula: 
  

											
	CR1	  	=	  	CR0	  	 x
  
	  	   OS0 + X  
	  	
	  	  	  	  	OS0 + Y	  	


 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;


  

 24 









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


 Any increase made under this Section 4.04(b) shall be made successively whenever any such
rights, options or warrants are issued and shall become effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that shares of Common Stock are not delivered after the expiration of such rights,
options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number
of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not
occurred. 
 In determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of
Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement for such issuance, 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, options 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) If the Company distributes shares of any
class of Capital Stock of the Company, evidences of its Indebtedness, other assets or property of the Company or rights, options or warrants to acquire the Company’s Capital Stock or other securities to all or substantially all holders of the
Common Stock, excluding: 
 (i) dividends, distributions, rights, options or warrants as to which an adjustment
was effected pursuant to Section 4.04(a) or Section 4.04(b) above; 
 (ii) dividends or distributions
paid exclusively in cash; and 
 (iii) Spin-Offs as to which provisions set forth below in this
Section 4.04(c) shall apply; 
  

 25 








 then the Conversion Rate shall be increased based on the following formula: 
  

											
	CR1	  	=	  	CR0	  	 x
  
	  	   SP0   
	  	
	  	  	  	  	SP0 - FMV	  	


 where, 
  

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


 If the Board of Directors determines the “FMV” (as defined above)
of any distribution for purposes of this Section 4.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing the Last
Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution. Notwithstanding the foregoing, if “FMV” (as defined above) is
equal to or greater than “SP0” (as defined above),
in lieu of the foregoing increase, each Holder of Notes shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of the Company’s Capital
Stock, evidences of Indebtedness, other assets or property of the Company or rights, options or warrants to acquire the Company’s Capital Stock or other securities that such Holder would have received if such Holder owned a number of shares of
Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. 
 Any increase made under the
above portion of this Section 4.04(c) shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to be the
Conversion Rate that would then be in effect if such distribution had not been declared. 
 With respect to an adjustment
pursuant to this Section 4.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other
business unit of the Company (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 
  

											
	CR1	  	=	  	CR0	  	 x
  
	  	   FMV0 + MP0  
	  	
	  	  	  	  	MP0	  	


  

 26 








 where, 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect immediately prior to the end of the Valuation Period;
			
	 CR1
	  	=	  	the Conversion Rate in effect immediately after the end of the Valuation Period;
			
	 FMV0
	  	=	  	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock
(determined for purposes of the definition of Last Reported Sale Price as if such Capital Stock or similar equity interest were Common Stock) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off
(the “Valuation Period”); and
			
	 MP0
	  	=	  	the average of the Last Reported Sale Prices of Common Stock over the Valuation Period.


 The adjustment to the Conversion Rate under the preceding paragraph shall occur on the last day
of the Valuation Period; provided that in respect of any conversion during the Valuation Period, references above to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including the
Ex-Dividend Date of such Spin-Off to, but excluding, the Conversion Date in determining the Applicable Conversion Rate. 
 For
the purposes of this Section 4.04(c) (and subject in all respects to Section 4.12), rights, options or warrants distributed by the Company to all holders of its Common Stock entitling them to subscribe for or purchase shares of the
Company’s Capital Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (a “Trigger Event”): (1) are deemed to be transferred with
such shares of Common Stock; (2) are not exercisable; and (3) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.04(c), (and no adjustment to the
Conversion Rate under this Section 4.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required)
to the Conversion Rate shall be made under this Section 4.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Supplemental Indenture, are subject to events, upon
the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of Indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of
distribution and Ex-Dividend Date of such deemed distribution (in which case the original rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders). In addition, in the event of any
distribution or deemed distribution of rights, options 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

  

 27 








 
calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 4.04(c) was made, (1) in the case of any such rights, options or warrants which shall
all have been redeemed or purchased without exercise by any Holders thereof, upon such final redemption or repurchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the
Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by
holders of Common Stock with respect to such rights, options or warrants (assuming each such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in
the case of such rights, options or warrants which shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued. 
 For purposes of this Section 4.04(c) and subsections (a) and (b) of this Section 4.04, any dividend or distribution to
which this Section 4.04(c) applies which also includes one or both of: 
  

	 	(A)	a dividend or distribution of shares of Common Stock to which Section 4.04(a) applies (the “Clause A Distribution”); 

  

	 	(B)	a dividend or distribution of rights, options or warrants to which Section 4.04(b) applies (the “Clause B Distribution”),


 then (1) such dividend or distribution, other than the Clause A Distribution and the Clause B
Distribution, shall be deemed to be a dividend or distribution to which this Section 4.04(c) applies (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 4.04(c) with respect thereto
shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 4.04(a) and Section 4.04(b) with
respect thereto shall then be made, except that, if determined by the Company, (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C
Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the open of business on such Ex-Dividend Date or such effective
date” within the meaning of Section 4.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 4.04(b). 
 (d) If any cash dividend or distribution is made to all, or substantially all, holders of the outstanding Common Stock, the Conversion Rate
shall be adjusted based on the following formula: 
  

											
	CR1	  	=	  	CR0	  	 x
  
	  	 SP0
	  	
	  	  	  	  	   SP0 – C  
	  	


 where, 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;


  

 28 









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


 If “C” (as defined above) is equal to or greater than “SP
0” (as defined above), in lieu of the foregoing
increase, each Holder shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of
shares of Common Stock equal to the Conversion Rate on the Ex-Dividend Date for such cash dividend or distribution. Such increase shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or
distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 (e) If the Company or any of its Subsidiaries make a payment in respect of a tender offer or exchange offer for Common Stock to the extent
that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Last Reported Sale Price of Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made
pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula: 
  

											
	CR1	  	=	  	CR0	  	 x
  
	  	     AC + (SP1 x OS1)    
	  	
	  	  	  	  	OS0 x SP1	  	


 where, 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange
offer expires;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange
offer expires;
			
	AC	  	=	  	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares purchased in such tender or exchange
offer;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all shares
accepted for purchase or exchange in such tender offer or exchange offer);

  

 29 









					
	OS1	  	=	    	the number of shares of Common Stock outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares accepted for
purchase or exchange in such tender or exchange offer); and
			
	SP1	  	=	    	the average of the Last Reported Sale Prices of Common Stock over the 10 consecutive Trading-Day period commencing on the Trading Day next succeeding the date such tender or
exchange offer expires.

 The adjustment to the Conversion Rate under this Section 4.04(e) shall occur
at the close of business on the 10th Trading Day
immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any conversion within 10 Trading Days immediately following, and including, the expiration date
of any tender or exchange offer, references in this Section 4.04(e) with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the expiration date of such tender or
exchange offer to, but excluding, the Conversion Date in determining the Applicable Conversion Rate. 
 If the Company or one of
its Subsidiaries is obligated to purchase shares of Common Stock pursuant to any such tender or exchange offer, but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchases or all such purchases are
rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made. 
 (f) If any distribution or transaction described in clauses (a) to (e) above has not yet resulted in an adjustment to the Applicable Conversion Rate on the Conversion Date, and the shares of
Common Stock Holders shall receive on settlement of the relevant conversion are not entitled to participate in the relevant distribution or transaction (because they were not held on a related record date or otherwise), then the Company shall adjust
the number of shares it delivers to Holders to reflect the relevant distribution or transaction. 
 (g) Notwithstanding anything
to the contrary in this Article 4, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date as described above, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related record date
would be treated as the record holder of shares of Common Stock as of the related Conversion Date as described in Section 4.03 based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the foregoing Conversion Rate
adjustment provisions, the Conversion Rate adjustment relating to such Ex-Dividend Date will not be made for such converting Holder. Instead, such Holder will be treated as if such Holder were the record owner of the shares of Common Stock on an
unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment. 
 (h)
“Ex-Dividend Date” shall mean the first date on which the shares of the Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive the issuance, dividend or distribution in
question. 
 (i) For purposes of this Section 4.04, “record date” shall mean, with respect to any
dividend, distribution or other transaction or event in which the holders of Common Stock have

  

 30 








 
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 shareholders 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). 
 (j) 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
Business Days, the increase is irrevocable during the period and the Board of Directors shall have made a determination that such increase would be in the best interests of the Company, which determination shall be conclusive. Whenever the
Conversion Rate is increased pursuant to this Section 4.04(j), 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. 
 (k) The Company may make such
increases in the Conversion Rate, in addition to any adjustments required by Sections 4.04(a), 4.04(b), 4.04(c), 4.04(d), 4.04(e) or 4.04(j), 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 shares (or rights to acquire shares) or from any event treated as such for income tax purposes. 
 (l) All calculations under this Article 4 shall be made by the Company and shall be made to the nearest cent (including, in the case of any
adjustment to the Conversion Rate, the resulting adjustment to the Conversion Price) or to the nearest one-ten-thousandth of a share (with one-half of a cent or five one-hundred-thousandths rounded upward), as the case may be. No adjustment shall be
required to be made for the Company’s issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or rights to purchase shares of Common Stock or such convertible or exchangeable securities,
other than as provided in this Section 4.04 and in Section 4.12. 
 (m) Whenever the Conversion Rate is adjusted as
herein provided, the Company shall promptly file with the Trustee and any Conversion Agent an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such
adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the
last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on
which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate to each Holder of the Notes. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. 
 (n) For purposes of this Section 4.04, the number of shares of Common Stock at any time outstanding shall not include shares held in
the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of
fractions of shares of Common Stock.

 (o) Notwithstanding the foregoing, if the application of the foregoing formulas would result
in a decrease in the Conversion Rate, no adjustment to the Conversion Rate shall be made (other than as a result of a share split or a share combination). 
 (p) Notwithstanding anything to the contrary in this Article 4, no adjustment to the Conversion Rate shall be made: 
 (i) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of
dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; 
 (ii) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed
by the Company or any of its Subsidiaries; 
 (iii) upon the issuance of any shares of Common Stock pursuant to
any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) of this Section 4.04(p) and outstanding as of the date the Notes were first issued; 
 (iv) for a change in the par value of the Common Stock; or 
 (v) for accrued and unpaid interest on the Notes, if any. 
 (q) No adjustment to the Conversion Rate shall be required unless the adjustment would require an increase or decrease of at least 1% of the
Conversion Rate. If an adjustment is not made because the adjustment does not change the Conversion Rate by at least 1%, then such adjustment will be carried forward and taken into account in any future adjustment. Notwithstanding the foregoing,
(i) upon any conversion of Notes (solely with respect to the Notes to be converted), (ii) on every one-year anniversary from the Issue Date of the Notes and (iii) on May 1, 2015, the Company shall give effect to all adjustments
that the Company has otherwise deferred pursuant to the immediately preceding sentence, and those adjustments will no longer be carried forward and taken into account in any future adjustment. 
 SECTION 4.05. Adjustments of Average Prices. Whenever any provision of the Indenture requires the Company to calculate the Last
Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and the Stock Price for purposes of a Make-Whole Fundamental Change), the Company shall
make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date of the event occurs, at any time during the
period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated. 
 SECTION 4.06. Adjustments Upon Certain Fundamental Changes. (a) If (i) a Fundamental Change (determined after giving effect to any exceptions to or exclusions from such definition, but
without regard to the proviso in clause (b) of the definition thereof) occurs or (ii) the Company calls the Notes for redemption pursuant to Article 9 (either event, a

  

 32 








 
“Make-Whole Fundamental Change”), and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under certain
circumstances, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”) as described below. A conversion of Notes shall be deemed for these
purposes to be “in connection with” a Make-Whole Fundamental Change described in clause (i) above if the Conversion Notice is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole Fundamental
Change up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause
(b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change). A conversion of Notes shall be deemed for these purposes to be “in connection with” a Make-Whole
Fundamental Change described in clause (ii) above if the Conversion Notice is received by the Conversion Agent from, and including, the date of issuance of a Redemption Notice pursuant to Article 9 up to, but excluding, the relevant Redemption
Date. The Company shall notify Holders of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date. 
 (b) The number of Additional Shares, if any by which the Conversion Rate will be increased shall be determined by reference to the table
attached as Schedule A hereto, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid (or deemed paid) per share
of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive only cash in any Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the
cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of Common Stock over the five Trading-Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the
Make-Whole Fundamental Change. In connection with a Make-Whole Fundamental Change triggered by a redemption of the Notes pursuant to Article 9, the Effective Date of such Make-Whole Fundamental Change shall be the date on which the Company issues
the relevant Redemption Notice. 
 (c) The Stock Prices set forth in the column headings of the table in Schedule A
hereto shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted pursuant to Section 4.04. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment,
multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of
Additional Shares set forth in such table shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 4.04. 
 (d) The table in Schedule A hereto sets forth the Effective Date and the number of Additional Shares to be added to the Conversion Rate per $1,000 principal amount of Notes for various Stock Prices
and Effective Dates. 
  

 33 








 The exact Stock Prices and Effective Dates may not be set forth in the table in Schedule
A, in which case: 
 (i) If the Stock Price is between two Stock Prices in the table or the Effective Date is
between two Effective Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and the later
Effective Dates, as applicable, based on a 365-day year. 
 (ii) If the Stock Price is greater than $100.00 per
share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table in Schedule A pursuant to clause (c)), no Additional Shares shall be added to the Conversion Rate. 
 (iii) If the Stock Price is less than $15.00 per share (subject to adjustment in the same manner as the Stock Prices as set
forth in the column headings of the table in Schedule A pursuant to clause (c)), no Additional Shares shall be added to the Conversion Rate. 
 Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock issuable upon conversion exceed 66.6667 shares of Common Stock per $1,000 principal amount of Notes, subject to adjustments in the same manner as
the Conversion Rate as set forth in Section 4.04. 
 SECTION 4.07. Effect of Recapitalization, Reclassification,
Consolidation, Merger or Sale. (a) In the case of: 
 (i) any recapitalization, reclassification or change of
the Common Stock (other than changes resulting from a subdivision or combination); 
 (ii) any consolidation,
merger or combination involving the Company; 
 (iii) any sale, lease or other transfer to a third party of the
consolidated assets of the Company and its Subsidiaries substantially as an entirety; or 
 (iv) any statutory
share exchange; 
 in each case as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other
property or assets (including cash or any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be
changed into a right to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock
equal to the Conversation Rate prior to such Merger Event would have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference Property” meaning the type and amount of Reference
Property that a holder of one share of Common Stock is entitled to receive) and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a
supplemental indenture (which shall comply with the Trust Indenture Act as in force at

  

 34 








 
the date of execution of such supplemental indenture) providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however, that at and after
the effective time of the Merger Event (i) the Company shall continue to have the right to determine the form of consideration to be paid and delivered, as the case may be, upon conversion of the Notes in accordance with Section 4.03 and
(ii) (x) any amount payable in cash upon conversion of the Notes in accordance with Section 4.03 shall continue to be payable in cash, (y) any shares of Common Stock that the Company would have been required to deliver upon
conversion of the Notes in accordance with Section 4.03 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have been entitled to receive in such Merger Event
and (z) the Daily VWAP shall be calculated based on the value of a unit of Reference Property. 
 If, as a result of the
Merger Event, each share of Common Stock is converted into the right to receive more than a single type of consideration (determined based in part upon any form of holder election), then (x) the Reference Property into which the Notes will be
convertible will be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election, and (y) the unit of Reference Property for purposes of the
foregoing paragraph shall refer to the consideration referred to in clause (x) attributable to one share of Common Stock. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted
average as soon as practicable after such determination is made. 
 The Company shall not become a party to any such Merger
Event unless its terms are consistent with this Section 4.07. Such supplemental indenture described in the second immediately preceding paragraph shall provide for adjustments which shall be as nearly equivalent to the adjustments provided for
in this Article 4 in the judgment of the Board of Directors or the board of directors of the successor Person. If, in the case of any such Merger Event, the Reference Property receivable thereupon by a holder of Common Stock includes shares of
stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing Person, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by
such other Person. 
 (b) The Company shall cause notice of the execution of such supplemental indenture to be mailed to each
Holder, at the address of such Holder as it appears on the register of the Notes maintained by the Registrar, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental
indenture. The above provisions of this Section 4.07 shall similarly apply to successive Merger Events. 
 SECTION 4.08. Taxes on Shares Issued. Any issue of stock certificates on conversions of Notes shall be made without charge to the converting Holder for any documentary, stamp or any similar issue or transfer tax in respect of
the issue thereof, and the Company shall pay any and all documentary, stamp or similar issue or transfer taxes that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Notes pursuant hereto. The Company
shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in any name other than that of the Holder of any Notes converted, and the Company shall
not be required to issue or deliver any such stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company
that such tax has been paid. 
  

 35 








 SECTION 4.09. 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 satisfy conversion of the
Notes from time to time as such Notes are presented for conversion (assuming that, at the time of the computation of such number of shares or securities, all such Notes would be converted by a single Holder and Physical Settlement is applicable).

 Before taking any action that 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 shall take all corporate action that 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 Price. 
 The Company covenants
that all shares of Common Stock that may be issued upon conversion of Notes shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and non-assessable and shall be free from preemptive rights and free
from any tax, lien or charge (other than those created by the Holder). 
 The Company shall list or cause to have quoted any
shares of Common Stock to be issued upon conversion of Notes on each national securities exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted. 
 SECTION 4.10. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or
responsibility to any Noteholder 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(s) 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 Notes; 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 Notes
for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 4. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall have
any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 4.07 relating either to the kind or amount of shares of stock or securities or property (including cash
or any combination thereof) receivable by Holders upon the conversion of their Notes after any event referred to in Section 4.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 6.01 of the
Original Indenture, may

  

 36 








 
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 4.11. Notice to
Holders Prior to Certain Actions. Unless a notice has been provided under Section 4.01(a)(iii) or Section 4.01(a)(iv), as applicable, in case: 
 (a) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Conversion Rate pursuant to Section 4.04; or 
 (b) the Company shall authorize the granting to the holders of all or substantially all of its Common Stock of rights, options or warrants
to subscribe for or purchase any share of any class or any other rights, options or warrants that would require an adjustment in the Conversion Rate pursuant to Section 4.04; 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 shareholders of the Company is required,
or of the sale, lease or transfer of all or substantially all of the assets of the Company or any of its Subsidiaries; or 
 (d)
of the voluntary or involuntary dissolution, liquidation or winding up of the Company or any of its Subsidiaries; 
 then, in each case, the
Company shall cause to be filed with the Trustee and the Conversion Agent and to be mailed to each Noteholder at such Holder’s address appearing in the Security Register, as promptly as practicable but in any event at least 30 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, options 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, lease, transfer, dissolution, liquidation or winding up
is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification,
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 4.12. Shareholder Rights Plan. Each share of
Common Stock, if any, issued upon conversion of Notes pursuant to this Article 4 shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such
legends, if any, in each case as may be provided by the terms of any shareholder rights plan adopted by the Company and in effect upon conversion of such Notes, as the same may be amended from time to time. If prior to any conversion, however, such
rights have separated from the shares of Common Stock in accordance with the provisions of the

  

 37 








 
applicable shareholder rights agreement, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all holders of the Common Stock, shares of the
Company’s Capital Stock, evidences of Indebtedness, assets, property, rights, options or warrants as described in Section 4.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

 SECTION 4.13. Company Determination Final. Any determination that the Company or the Board of Directors must make
pursuant to this Article 4 shall be conclusive if made in good faith, absent manifest error. 
 ARTICLE 5 
 EVENTS OF DEFAULT; REMEDIES 
 SECTION 5.01. Events of Default. Article Five of the Original Indenture shall not apply to the Notes. Instead, the events of default provisions set forth in this Article 5 shall, with respect
to the Notes, supersede in their entirety Article Five of the Original Indenture, and all references in the Original Indenture to Article Five thereof and events of default provisions therein, as the case may be, shall, with respect to the Notes, be
deemed to be references to this Article 5 and events of default provisions set forth in this Article 5, respectively. Each of the following events shall be an “Event of Default” wherever used herein with respect to the Notes:

 (a) default in the payment of the principal amount on any Note when due at the Stated Maturity, upon redemption, repurchase,
declaration of acceleration or otherwise; 
 (b) default in the payment of any interest (including Additional Interest, if any)
on any Notes when due and payable and such failure continues for a period of 30 days past the applicable due date; 
 (c)
failure by the Company to provide the Fundamental Change Company Notice or notice of a specified corporate transaction required pursuant to Section 3.01(b) or Section 4.01(a)(iii) or 4.01(a)(iv), in each case when due; 
 (d) failure by the Company’s to comply with its obligation to convert the Notes in accordance with Article 4 hereof upon exercise of
any Holder’s conversion right; 
 (e) failure by the Company to pay the Fundamental Change Repurchase Price pursuant to
Section 3.01(a) when due; 
 (f) failure by the Company to comply with its obligations under Article 8; 
 (g) failure by the Company to perform or observe any covenant of the Company in the Indenture, and such failure (other than a covenant a
default in whose performance or whose breach is elsewhere in this Section 5.01 specifically dealt with) continues for a period of 30 days after there has been given, by registered or certified mail, to the Company from the Trustee or to the
Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Outstanding Notes a written notice, in each case received by the Company (and the Trustee, if applicable), specifying such default and requiring it to be
remedied and stating that such notice is a “Notice of Default” hereunder; provided, however, that the Company shall have 60 days after

  

 38 








 
receipt of such notice to remedy any failure to comply with its obligations to deliver to the Trustee any documents or reports that the Company is required to file with the Commission pursuant to
Section 2.03 of this Supplemental Indenture and Section 7.04 of the Original Indenture; 
 (h) default by the Company
or any Significant Subsidiary of the Company with respect to any mortgage, agreement or other instrument under which there may be outstanding, or by which there may be secured or evidenced, any Indebtedness for money borrowed in excess of $10
million in the aggregate of the Company and/or any Significant Subsidiary of the Company, whether such Indebtedness now exists or shall hereafter be created (i) resulting in such Indebtedness becoming or being declared due and payable or
(ii) constituting a failure to pay the principal or interest of any such debt when due and payable at its stated maturity, upon required repurchase, upon declaration or otherwise; 
 (i) the entry by a court having jurisdiction in the premises of (i) a decree or order for relief in respect of the Company or any
Significant Subsidiary of the Company in an involuntary case or proceeding under any applicable federal or state bankruptcy, insolvency, reorganization or other similar law, (ii) a decree or order adjudging the Company or any Significant
Subsidiary of the Company as bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company or the under any applicable federal or state law or
(iii) appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any Significant Subsidiary of the Company of any substantial part of its property, or ordering the winding up or
liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days; 
 (j) the commencement by the Company or by any Significant Subsidiary of the Company of a voluntary case or proceeding under any applicable
federal or state bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree or order for relief in respect of the Company or
of any Significant Subsidiary of the Company in an involuntary case or proceeding under any applicable federal or state bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or
proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable federal or state law, or the consent by it to the filing of such petition or to the appointment of or taking
possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any Significant Subsidiary of the Company or of any substantial part of its property, or the making by it of an
assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company or by any Significant Subsidiary of the Company in
furtherance of any such action; or 
 (k) a final judgment for the payment of $10 million or more (excluding any amounts covered
by insurance) rendered against the Company or any Significant Subsidiary of the Company, which judgment is not discharged or stayed within 60 days after (i) the date on which the right to appeal thereof has expired if no such appeal has
commenced, or (ii) the date on which all rights to appeal have been extinguished. 
  

 39 








 The foregoing shall constitute Events of Default whatever the reason for any such Event of
Default and whether it is voluntary or involuntary or is 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. 
 SECTION 5.02. Acceleration of Maturity; Rescission and Annulment. (a) Subject to Section 5.17, if an Event of Default
(other than those specified in Sections 5.01(i) and 5.01(j) solely with respect to the Company) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the Outstanding
Notes may (and the Trustee upon request of such Holders shall) declare the principal plus any accrued and unpaid interest on, all the Outstanding Notes to be immediately due and payable, by a notice in writing to the Company (and to the Trustee if
given by Holders), and upon any such declaration such principal amount plus any accrued and unpaid interest shall become immediately due and payable. 
 Notwithstanding the foregoing, in the case of an Event of Default specified in Section 5.01(i) or Section 5.01(j) solely with respect to the Company, the principal amount plus any accrued and
unpaid interest on all Outstanding Notes will ipso facto become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. 
 (b) At any time after such a declaration of acceleration has been made, the Holders of a majority in aggregate principal amount of the
Outstanding Notes, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences (other than with respect to an Event of Default under Sections 5.01(a), 5.01(b), 5.01(d), 5.01(e) or an Event of Default
in respect of any covenant that cannot be amended without the consent of each Holder affected under Section 7.02) if: 
 (i) such rescission and annulment will not conflict with any judgment or decree of a court of competent jurisdiction; and 
 (ii) all Events of Default, other than the non-payment of the principal amount plus accrued and unpaid interest on Notes that
have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.12. 
 No
such rescission shall affect any subsequent default or impair any right consequent thereon. 
 SECTION 5.03. Collection
of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if a Default is made in the payment of the principal amount plus accrued and unpaid interest at the Maturity thereof or in the payment of the Redemption Price or
Fundamental Change Repurchase Price in respect of any Note, the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes, and, in addition thereto, such
further amounts required pursuant to Section 5.07. 
 If an Event of Default occurs and is continuing, the Trustee may, but
shall not be obligated to, pursue any available remedy to collect the payment of the principal amount plus accrued but unpaid interest on the Notes or to enforce the performance of any provision of the

  

 40 








 
Notes or the Indenture. The Trustee may maintain a proceeding even if the Trustee does not possess any of the Notes or does not produce any of the Notes in the proceeding. A delay or omission by
the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of, or acquiescence in, the Event of Default. No remedy is exclusive of any other remedy. All
available remedies are cumulative. 
 SECTION 5.04. Trustee May File Proofs of Claim. In case of any judicial
proceeding relative to the Company (or any other obligor upon the Notes), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the
Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event
that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other
amounts due the Trustee under Section 6.07 of the Original Indenture. 
 No provision of the Indenture shall be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding. 
 SECTION 5.05. Application of Money Collected.
Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money to Holders, upon presentation of the Notes and the
notation thereon of 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 6.07 of the Original Indenture; 
 SECOND: To the
payment of the amounts then due and unpaid on the Notes for the principal amount, Redemption Price, Fundamental Change Repurchase Price or interest, as the case may be, in respect of which or for the benefit of which such money has been collected,
ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes; and 
 THIRD: To the payment of the remainder, if any, to the Company or any other Person lawfully entitled thereto. 
 SECTION 5.06. Limitation on Suits. No Holder of any Note shall have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder (other than in the case of a Default specified in Section 5.01(a) or 5.01(b)), unless: 
 (i) such Holder has previously given written notice to the Trustee of a continuing Default; 
  

 41 








 (ii) the Holders of at least 25% in aggregate principal amount of the
Outstanding Notes shall have made written request to the Trustee to pursue such remedy in its own name as Trustee hereunder; 
 (iii) no direction, in the opinion of the Trustee, inconsistent with such written request has been given to the Trustee by the Holders of a majority in aggregate principal amount of the Outstanding Notes;

 (iv) such Holder or Holders have provided to the Trustee security or indemnity reasonably satisfactory to the
Trustee against the expenses, losses and liabilities to be incurred in compliance with such request; and 
 (v)
the Trustee for 60 days after its receipt of such notice, request and provision of adequate security or indemnity has failed to institute any such proceeding; 
 it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing itself of, any provision of the Indenture to affect, disturb or
prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under the Indenture, except in the manner herein provided and for the equal and ratable benefit of all
the Holders. 
 SECTION 5.07. Unconditional Right of Holders to Receive Payment. Notwithstanding any other provision
of the Indenture, the right of any Holder to receive payment of the principal amount, Redemption Price, Fundamental Change Repurchase Price or accrued and unpaid interest in respect of the Notes held by such Holder, on or after the respective due
dates expressed in the Notes or any Redemption Price or Fundamental Change Repurchase Date, as applicable, and to convert the Notes in accordance with Article 4, or to bring suit for the enforcement of any such payment on or after such respective
dates or the right to convert, shall not be impaired or affected adversely without the consent of such Holder. 
 SECTION 5.08. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under the Indenture and such proceeding has been discontinued or abandoned for any
reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their
former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 
 SECTION 5.09. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of
Section 3.06 of the Original Indenture, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by
law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder shall not prevent the concurrent assertion
or employment of any other appropriate right or remedy. 
  

 42 








 SECTION 5.10. Delay or Omission Not Waiver. No delay or omission of the Trustee
or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by
this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
 SECTION 5.11. Control by Holders. The Holders of a majority in principal amount of the Outstanding Notes shall have the right to
direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, provided that: 
 (i) such direction shall not be in conflict with any rule of law or with the Indenture; and 
 (ii) the Trustee may refuse to follow any such direction that the Trustee determines is unduly prejudicial to the rights of
any other Holder or that would involve the Trustee in personal liability. 
 SECTION 5.12. Waiver of Past Defaults.
The Holders of not less than a majority in aggregate principal amount of the Outstanding Notes may on behalf of the Holders of all the Notes waive any past Default hereunder and its consequences, except a Default: 
 (i) described in Section 5.01(a), 5.01(b), 5.01(d) or 5.01(e); or 
 (ii) in respect of a covenant or provision hereof which under Article 7 cannot be modified or amended without the consent of
the Holder of each Outstanding Note affected. 
 Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose of the Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 
 When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent
right. This Section 5.12 shall be in lieu of Section 316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) is hereby expressly excluded from the Indenture, as permitted by the Trust Indenture Act. 
 SECTION 5.13. Undertaking for Costs. In any suit for the enforcement of any right or remedy under the Indenture or in any suit
against the Trustee for any action taken or omitted by it as Trustee, in either case in respect of the Notes, a court may require any party litigant in such suit to file an undertaking to pay the costs of the suit, and the court may assess
reasonable costs, including reasonable attorney’s fees and expenses, against any party litigant in the suit having due regard to the merits and good faith of the claims or defenses made by the party litigant; but the provisions of this
Section 5.13 shall not apply to any suit instituted by the Company, to any

  

 43 








 
suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Notes, or to any suit
instituted by any Holder for the enforcement of the payment of the principal amount on any Note on or after Maturity of such Note, the Redemption Price or the Fundamental Change Repurchase Price. 
 SECTION 5.14. Waiver of Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it will
not at any time insist upon, or 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 or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of the Indenture; and the Company (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law and covenants that it will not 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 5.15. Violation of Certain Covenants. A violation of Section 3.06 or any other
covenant or agreement in the Indenture that expressly provides that a violation of such covenant or agreement shall not constitute an Event of Default may only be enforced by the Trustee by instituting a legal proceeding against the Company for
enforcement of such covenant or agreement. 
 SECTION 5.16. Notice of Default. If a Default or Event of Default
under the Indenture occurs and is continuing and is known to the Trustee, the Trustee shall give notice of such Default or Event of Default to each Holder of the Notes within 90 days after it occurs. The Trustee may withhold notice to the Holders of
the Notes of any Event of Default, except defaults in payment of principal of or interest on the Notes, if and so long as a committee of the trust officers of the Trustee in good faith determines that the withholding of such notice is in the
interest of the Holders of the Notes. 
 SECTION 5.17. Alternative Remedy for Failure to Comply with Reporting
Obligations in the Indenture and Trust Indenture Act. Notwithstanding anything to the contrary in the Indenture, to the extent elected by the Company in its sole discretion, the sole remedy for an Event of Default described in
Section 5.01(g) above relating to the failure to comply with Section 7.04 of the Original Indenture as modified by Section 2.03 of this Supplemental Indenture or the failure to comply with the requirements of Section 314(a)(1) of
the Trust Indenture Act will for the first 60 days after the occurrence of such an Event of Default consist exclusively of the right to receive additional interest on the Notes at a rate equal to 0.25% per annum of the principal amount of the
Notes (the “Additional Interest”). This Additional Interest will be payable in the same manner and on the same dates as the stated interest payable on the Notes. The Additional Interest will accrue on all Outstanding Notes from and
including the date on which an Event of Default relating to the failure to comply with Section 7.04 of the Original Indenture as modified by Section 2.03 of this Supplemental Indenture or the failure to comply with Section 314(a)(1)
of the Trust Indenture Act first occurs to, but not including, the 61st day thereafter (or such earlier date on which the Event of Default relating to the failure to comply with Section 7.04 of the Original Indenture as modified by
Section 2.03 of this Supplemental

  

 44 








 
Indenture or the failure to comply with Section 314(a)(1) of the Trust Indenture Act shall have been cured or waived). On such 61st day (or earlier, if the Event of Default relating to the
failure to comply with Section 7.04 of the Original Indenture as modified by Section 2.03 of this Supplemental Indenture or the failure to comply with Section 314(a)(1) of the Trust Indenture Act is cured or waived prior to such 61st
day), such Additional Interest will cease to accrue and, if the Event of Default relating to the failure to comply with Section 7.04 of the Original Indenture as modified by Section 2.03 of this Supplemental Indenture or the failure to
comply with Section 314(a)(1) of the Trust Indenture Act has not been cured or waived prior to such 61st day, the Notes will be subject to acceleration as provided in Section 5.02 hereof. The provisions of this paragraph shall not affect
the rights of Holders of Notes in the event of the occurrence of any other Event of Default. In the event the Company does not timely elect to pay the Additional Interest upon an Event of Default relating to the failure to comply with
Section 7.04 of the Original Indenture as modified by Section 2.03 of this Supplemental Indenture or the failure to comply with Section 314(a)(1) of the Trust Indenture Act in accordance with this paragraph, the Notes shall be subject
to acceleration as provided in Section 5.02 hereof. To make such election, the Company must notify the Holders, the Trustee and the Paying Agent of such election on or prior to the date such failure to comply with Section 7.04 of the
Original Indenture as modified by Section 2.03 of this Supplemental Indenture or the failure to comply with Section 314(a)(1) of the Trust Indenture Act becomes an Event of Default. 
 ARTICLE 6 
 SATISFACTION AND DISCHARGE

 SECTION 6.01. Satisfaction and Discharge of the Supplemental Indenture. Articles Four and Thirteen of the
Original Indenture shall not apply to the Notes. Instead, the satisfaction and discharge provisions set forth in this Article 6 shall, with respect to the Notes, supersede in their entirety Articles Four and Thirteen of the Original Indenture, and
all references in the Original Indenture to Articles Four and Thirteen thereof and satisfaction and discharge provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 6 and the satisfaction
and discharge provisions set forth in this Article 6, respectively. When (a) the Company shall deliver to the Registrar for cancellation all Notes theretofore authenticated (other than any Notes that have been destroyed, lost or stolen and in
lieu of or in substitution for which other Notes shall have been authenticated and delivered) and not theretofore canceled, or (b) all the Notes not theretofore canceled or delivered to the Trustee for cancellation shall have become due and
payable (whether at the Stated Maturity, on any Redemption Date or Fundamental Change Repurchase Date, upon conversion or otherwise) and the Company shall deposit with the Trustee, in trust, or deliver to the Holders, as applicable, cash or cash
and/or shares of Common Stock, solely to satisfy outstanding conversions, as applicable, sufficient to pay all amounts due (and shares of Common Stock deliverable following conversion, if applicable) on all of such Notes (other than any Notes that
shall have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Notes shall have been authenticated and delivered) not theretofore canceled or delivered to the Trustee for cancellation, including principal and
interest due, accompanied, except in the event the Notes are due and payable solely in cash at the Stated Maturity of the Notes or upon an earlier Redemption Date or Fundamental Change Repurchase Date, by a verification report as to the sufficiency
of the deposited amount from an independent certified accountant or other financial professional reasonably satisfactory to the Trustee (which may include any of the Underwriters), and if the

  

 45 








 
Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this Supplemental Indenture shall cease to be of further effect (except as to (i) rights
hereunder of Holders of the Notes to receive all amounts owing upon the Notes and the other rights, duties and obligations of Holders of the Notes, as beneficiaries hereof with respect to the amounts, if any, so deposited with the Trustee and
(ii) 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 1.03 of the Original
Indenture and at the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Supplemental Indenture; the Company, however, hereby agrees to reimburse the Trustee for any costs or expenses
thereafter reasonably and properly incurred by the Trustee, including the fees and expenses of its counsel, and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this
Supplemental Indenture or the Notes. 
 SECTION 6.02. Deposited Monies to Be Held in Trust by Trustee. Subject to
Section 6.04, all monies and shares of Common Stock, if any, deposited with the Trustee pursuant to Section 6.01 shall be held in trust for the sole benefit of the Holders of the Notes, and such monies and shares of Common Stock 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, settlement or redemption of which such monies or
shares of Common Stock have been deposited with the Trustee, of all sums or amounts due and to become due thereon for principal and interest, if any. 
 SECTION 6.03. Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of the Indenture, all monies and shares of Common Stock, if any, then held by any Paying Agent (if other
than the Trustee) shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon such Paying Agent shall be released from all further liability with respect to such monies and shares of Common Stock. 
 SECTION 6.04. Return of Unclaimed Monies. Subject to the requirements of applicable law, any monies and shares of Common Stock
deposited with or paid to the Trustee for payment of the principal of or interest, if any, on the Notes and not applied but remaining unclaimed by the Holders of the Notes for two years after the date upon which the principal of or interest, if any,
on such Notes, as the case may be, shall have become due and payable, shall be repaid to the Company by the Trustee on demand, and all liability of the Trustee shall thereupon cease with respect to such monies and shares of Common Stock; and the
Holder of any of the Notes shall thereafter look only to the Company for any payment or delivery that such Holder of the Notes may be entitled to collect unless an applicable abandoned property law designates another Person. 
 SECTION 6.05. Reinstatement. If the Trustee or the Paying Agent is unable to apply any money or shares of Common Stock in
accordance with Section 6.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under the Indenture and the Notes shall be
revived and reinstated as though no deposit had occurred pursuant to Section 6.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money and shares of Common Stock in accordance with Section 6.02;
provided, however, that if the Company makes

  

 46 








 
any payment of interest on, principal of or payment or delivery in respect 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 or shares of Common Stock, if any, held by the Trustee or Paying Agent. 
 ARTICLE 7 
 SUPPLEMENTAL INDENTURES 
 SECTION 7.01. Supplemental Indentures Without Consent of Holders. Section 9.01 of the Original Indenture shall not apply to
the Notes. Instead, the provisions set forth in this Section 7.01 shall, with respect to the Notes, supersede in their entirety Section 9.01 of the Original Indenture, and all references in the Original Indenture to Section 9.01
thereof and provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Section 7.01 and provisions set forth in this Section 7.01, respectively. The Company and the Trustee may modify or
amend the Indenture or the Notes without the consent of any Noteholder to: 
 (i) add guarantees with respect to
the Notes or secure the Notes;

 (iv) add covenants or Events of Default for the benefit of the Holders of the Notes;

 47 








 (x) make other changes to the Indenture or forms or terms of the Notes so
long as no such change individually or in the aggregate with all other such changes has or will have a material adverse effect on the interests of the Holders of the Notes. 
 SECTION 7.02. Supplemental Indentures With Consent of Holders. Section 9.02 of the Original Indenture shall not apply to
the Notes. Instead, the provisions set forth in this Section 7.02 shall, with respect to the Notes, supersede in their entirety Section 9.02 of the Original Indenture, and all references in the Original Indenture to Section 9.02
thereof and provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Section 7.02 and provisions set forth in this Section 7.02, respectively. Except as provided below in this
Section 7.02 and in Section 7.01, the Indenture or the Notes may be amended, modified or supplemented, and noncompliance in any particular instance with any provision of the Indenture or the Notes may be waived, in each case with the
written consent of the Holders of at least a majority of the principal amount of the Notes at the time Outstanding. Without the written consent or the affirmative vote of each Holder of Outstanding Notes affected thereby, an amendment, supplement or
waiver under this Section 7.02 may not: 
 (i) reduce the principal amount of or change the Stated Maturity
of any Note; 
 (ii) reduce the rate of accrual for, or extend the time for payment of interest on any Note;

 (iii) reduce the Redemption Price or Fundamental Change Repurchase Price or change the time at which or

 (vii) reduce the quorum or voting requirements under the Indenture; 
 (viii) change the Company’s obligation to maintain an office or agency in the places and for the purposes specified in

 (x) reduce the percentage of the aggregate principal amount of the Outstanding Notes the consent of whose Holders is required
for any such supplemental indenture entered into in accordance with this Section 7.02 or the consent of whose Holders is required for any waiver provided for in the Indenture. 
  

 48 








 It shall not be necessary for any Act of Holders under this Section 7.02 to approve the
particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof. 
 SECTION 7.03. Notice to Holders of Supplemental Indentures. The Company shall cause notice of the execution of any supplemental indenture to be mailed to each Noteholder, at his address appearing on the Security Register
provided for in the Indenture, within 20 days after execution thereof. Failure to deliver such notice, or any defect in such notice, shall not affect the legality or validity of such supplemental indenture. 
 ARTICLE 8 
 CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE 
 SECTION 8.01. Company May Consolidate, etc.,
Only on Certain Terms. In addition to the provisions set forth under Article Eight of the Original Indenture, the Company shall not consolidate with or merge with or into any other Person or convey, transfer or lease all or substantially all its
assets to another Person, unless: 
 (a) the resulting, surviving or transferee Person (if not the Company) (the
“Successor Company”) shall be a corporation organized and existing under (i) the laws of the United States of America, any state thereof or the District of Columbia, or (ii) any other jurisdiction so long as the Successor
Company agrees to submit to service of process in any state in the United States of America or the District of Columbia and, in the case of clause (ii) above, the Successor Company provides a full and unconditional indemnity and provision for
additional amounts required to be withheld from payments or deliveries to Holders or beneficial owners of the Notes under applicable United States or foreign laws, rules, regulations or authorities, and any other incremental tax liabilities or costs
of such Holders or beneficial owners as a result of such merger or other transaction, and in each case the Successor Company (if not the Company) will expressly assume, by a supplemental indenture, executed and delivered to the Trustee, in form
reasonably satisfactory to the Trustee, all of the Company’s obligations under the Notes and the Indenture; 
 (b)
immediately after giving effect to such transaction, no Default shall have occurred and be continuing; 
 (c) the Company shall
have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and, if a supplemental indenture is required in connection with such transaction, such supplemental
indenture, comply with the Indenture; and 
 (d) the Company shall have delivered to the Trustee an Opinion of Counsel to the
effect that the Holders or beneficial owners of the Notes will not recognize income, gain or loss for United States federal income tax purposes as a result of such transaction and will be subject to United States federal income tax in the same
amount, in the same manner and at the same times as would have been the case if the transaction had not occurred, except where any of the foregoing are subject to the indemnification provided for in Section 8.01(a) above. 
  

 49 








 For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise) of the
properties and assets of one or more Subsidiaries (other than to the Company or another Subsidiary), which, if such assets were owned by the Company, would constitute all or substantially all of the properties and assets of the Company and its
Subsidiaries, taken as a whole, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company. 
 The Successor Company formed by such consolidation or into which the Company is merged or the Successor Company to which such conveyance, transfer, lease or other disposition is made shall succeed to, and
be substituted for, and may exercise every right and power of, the Company under the Indenture with the same effect as if such successor had been named as the Company herein; and thereafter, except in the case of a conveyance, transfer or lease of
all or substantially all the Company’s assets (in which case the Company will not be discharged from the obligation to pay the principal amount of and interest on the Notes) and except for obligations, if any, that the Company may have under a
supplemental indenture, the Company shall be discharged from all obligations and covenants under the Indenture and the Notes. Subject to Section 9.03 of the Original Indenture, the Company, the Trustee and the Successor Company shall enter into
a supplemental indenture to evidence the succession and substitution of such Successor Company and such discharge and release of the Company. 
 ARTICLE 9 
 REDEMPTION 
 SECTION 9.01. Notice to Trustee. Article Eleven of the Original Indenture shall not apply to the Notes. Instead, the redemption
provisions set forth in this Article 9 shall, with respect to the Notes, supersede in their entirety Article Eleven of the Original Indenture, and all references in the Original Indenture to Article Eleven thereof and redemption provisions therein,
as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 9 and redemption provisions set forth in this Article 9, respectively. The Company may not redeem the Notes prior to November 1, 2012. On or after
November 1, 2012 and prior to the Stated Maturity, the Company may redeem for cash all, but not less than all, of the Notes if the Last Reported Sale Price of the Company’s Common Stock equals or exceeds 130% of the Conversion Price then
in effect for 20 or more Trading Days in a period of 30 consecutive Trading Days ending on the Trading Day immediately prior to the date of the Redemption Notice, at 100% of the principal amount of the Notes to be redeemed plus any accrued and
unpaid interest, to, but excluding, the Redemption Date (the “Redemption Price”), unless the Redemption Date falls after a Regular Record Date but on or prior to the immediately succeeding Interest Payment Date, in which case the
Company shall instead pay the full amount of accrued and unpaid interest to the Holder of the Notes as of such Regular Record Date, and the Redemption Price will be equal to 100% of the principal amount of the Notes to be redeemed. No Notes may be
redeemed if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Redemption Date (except in the case of an acceleration resulting from a default by the Company in the payment of the
Redemption Price with respect to such Notes). 
 SECTION 9.02. Redemption Notice. Not more than 45 calendar days but
not less than 30 calendar days prior to the Redemption Date, the Company shall notify mail a notice of redemption (the “Redemption Notice”) by first-class mail to the Trustee, the Paying Agent and each Holder of Notes to be redeemed
at such Holder’s address set forth in the Security Register. 
  

 50 








 The notice shall identify the Notes to be redeemed and shall state: 
 (a) the Redemption Date (which must be a Business Day); 
 (b) the Redemption Price; 
 (c) the Applicable Conversion Rate (including any
Additional Shares pursuant to Section 4.06(a)) if a Holder converts its Notes in connection with the Company’s election to redeem the Notes. 
 (d) the name and address of the Paying Agent; 
 (e) that Notes must be surrendered
to the Paying Agent to collect the Redemption Price; 
 (f) that, unless the Company defaults in making such redemption payment
or the Paying Agent is prohibited from making such payment pursuant to the terms of the Indenture, interest on Notes shall cease to accrue on and after the Redemption Date; 
 (g) the paragraph of the Notes and/or provision of the Indenture pursuant to which the Notes are being redeemed; 
 (h) the CUSIP or ISIN number, if any, printed on the Notes; and 
 (i) that no representation is made as to the correctness or accuracy of the CUSIP or ISIN number, if any, listed in such notice or printed
on the Notes. 
 At the Company’s request, the Trustee shall give the Redemption Notice as provided to it in the
Company’s name and at the Company’s expense. In such event, the Company shall provide the Trustee with the information required by this Section. 
 SECTION 9.03. Effect of Redemption Notice. Once Redemption Notice is mailed, all Notes shall become due and payable on the Redemption Date and at the Redemption Price stated in the notice.
Upon surrender to the Paying Agent, such Notes shall be paid at the Redemption Price stated in the notice. 
 Failure to give
notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder. 
 SECTION 9.04. Deposit of Redemption Price. Prior to 11:00 a.m. (New York City time) on the Redemption Date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate
of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 10.03 of the Original Indenture) an amount of money (in immediately available funds if deposited on such Business Day) sufficient to pay
the Redemption Price of, and if the Redemption Date falls after a Regular

  

 51 








 
Record Date but on or prior to the immediately succeeding Interest Payment Date, accrued and unpaid interest on, all Notes as of the Redemption Date, other than Notes called for redemption that
have been delivered by the Company to the Trustee for cancellation. 
 SECTION 9.05. Repayment to the Company. The
Trustee and the Paying Agent shall return to the Company any cash that remains unclaimed, together with interest, if any, thereon, held by them for the payment of the Redemption Price of all Notes upon redemption of the Notes; provided that
to the extent that the aggregate amount of cash deposited by the Company pursuant to Section 9.04 exceeds the aggregate Redemption Price of all Notes Outstanding, then as soon as practicable following the Redemption Date, the Trustee or the
Paying Agent, as the case may be, shall return any such excess to the Company.

 [FORM OF REVERSE OF NOTE] 
 GMX RESOURCES INC. 
 4.50% Convertible Senior

	1.	Interest 

 (a) GMX
RESOURCES INC., an Oklahoma corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this
Note at the rate of 4.50% per annum. The Company will pay interest semiannually on May 1 and November 1 of each year commencing on May 1, 2010. Interest on the Note will accrue from the most recent date on which interest has been
paid or duly provided for, if no interest has been paid, from October 28, 2009. Interest will be computed on the basis of a 360-day year of twelve 30-day months. If a payment date is not a Business Day, payment will be made on the next
succeeding Business Day, and no additional interest will accrue in respect of such payment by virtue of the payment being made on such later date. 
 (b) The Company may elect to pay Additional Interest on this Note as a remedy for an Event of Default relating to a failure to file with the Trustee reports required under the Exchange Act pursuant to the
terms of the Indenture and the Trust Indenture Act. 
 (c) Except as otherwise specifically set forth, all references herein to
“interest” include Additional Interest that the Company elects to pay in connection with a failure to file reports required under the Exchange Act pursuant to the terms of the Indenture and the Trust Indenture Act.

 The Company issued the Notes under an Indenture dated as of October 28, 2009 (the “Original Indenture”), between the Company and the Trustee as supplemented by the First Supplemental Indenture dated as of
October 28, 2009 (herein called the “Supplemental Indenture” and the Original Indenture, as supplemented by the Supplemental Indenture, the “Indenture”). The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 as in effect on the date of the Indenture (the “Trust Indenture Act”). Terms defined in the Indenture and not defined herein have the

the Notes if the Last Reported Sale Price of the Common Stock equals or exceeds 130% of the Conversion Price then in effect for 20 or more Trading Days in a period of 30 consecutive Trading Days ending on the Trading Day immediately prior to the
date of the Redemption Notice. 
  

	6.	Repurchases upon Fundamental Change 

 Upon the occurrence of a Fundamental Change, the Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash at a price equal to the Repurchase Price all of

Notes may declare the principal of and accrued but unpaid interest on all the Notes to be due and payable. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company occurs, the principal of and
interest on all the Notes will become immediately due and payable without any declaration or other act on the part of the Trustee or any Noteholder.

Company or the Trustee with respect to the Company’s obligations on the Notes or the obligations of the Company or the Trustee under this Supplemental Indenture or any certificate or other writing delivered in connection herewith. Each Holder
