or the parent thereof, in substantially the same proportions vis-à-vis each other as immediately before such transaction will be deemed not to be a Fundamental
Change pursuant to this clause (B); 
 (C)    the Company’s stockholders approve any plan or proposal for
the liquidation or dissolution of the Company; or 
 (D)    the Common Stock ceases to be listed on any of The New York

as reported in composite transactions for the principal U.S. national or regional securities exchange on which the Common Stock is then listed. If the Common Stock is not listed on a U.S. national or regional securities exchange on such Trading Day,
then the Last Reported Sale Price will be the last quoted bid price per share of Common Stock on such Trading Day in the over-the-counter market as reported by OTC
Markets Group Inc. or a similar organization. If the Common Stock is not so quoted on such Trading Day, then the Last Reported Sale Price will be the average of the mid-point of the last bid price and the last
ask price per share of Common Stock on such Trading Day from each of at least three (3) nationally recognized independent investment banking firms selected by the Company, which may include the Initial Purchaser. Neither the Trustee nor the
Conversion Agent will have any duty to determine the Last Reported Sale Price.

Note as the date from, and including, which Stated Interest will begin to accrue in such circumstance) to, but excluding, the date of payment of such Stated Interest; and (ii) be, subject to Sections 4.02(D), 4.03(E) and
5.02(D) (but without duplication of any payment of interest), payable semi-annually in arrears on each Interest Payment Date, beginning on the first Interest Payment Date set forth in the certificate representing such Note, to the Holder of
such Note as of the Close of Business on the immediately preceding Regular Record Date. Stated Interest, and, if applicable, Additional Interest and Special Interest, on the Notes will be computed on the basis of a
360-day year comprised of twelve 30-day months. 

(B)    Defaulted Amounts. If the Company fails to pay any amount (a “Defaulted Amount”) payable on
a Note on or before the due date therefor as provided in this Indenture, then, regardless of whether such failure constitutes an Event of Default, (i) such Defaulted Amount will forthwith cease to be payable to the Holder of such Note otherwise
entitled to such payment; (ii) to the extent lawful, interest (“Default Interest”) will accrue on such Defaulted Amount at a rate per annum equal to the rate per annum at which Stated Interest accrues, from, and including, such
due date to, but excluding, the date of payment of such Defaulted Amount and Default Interest; (iii) such Defaulted Amount and Default Interest will be paid on a payment date selected by the Company to the Holder of such Note as of the Close of
Business on a special record date selected by the Company, provided that such special record date must be no more

than fifteen (15), nor less than ten (10), calendar days before such payment date; and (iv) at least fifteen (15) calendar days before such special record date, the Company will send
notice to the Trustee and the Holders that states such special record date, such payment date and the amount of such Defaulted Amount and Default Interest to be paid on such payment date. 

(C)    Delay of Payment when Payment Date is Not a Business Day. If the due date for a payment on a Note as
provided in this Indenture is not a Business Day, then, notwithstanding anything to the contrary in this Indenture or the Notes, such payment may be made on the immediately following Business Day and no interest will accrue on such payment as a
result of the related delay. Solely for purposes of the immediately preceding sentence, a day on which the applicable place of payment is authorized or required by law or executive order to close or be closed will be deemed not to be a
“Business Day.” 
 Section 2.06. REGISTRAR, PAYING AGENT
AND CONVERSION AGENT. 
 (A)    Generally. The Company will
maintain (i) an office or agency in the continental United States where Notes may be presented for registration of transfer or for exchange (the “Registrar”); (ii) an office or agency in the continental United States where
Notes may be presented for payment (the “Paying Agent”); and (iii) an office or agency in the continental United States where Notes may be presented for conversion (the “Conversion Agent”). If the Company fails
to maintain a Registrar, Paying Agent or Conversion Agent, then the Trustee will act as such. For the avoidance of doubt, the Company or any of its Subsidiaries may act as Registrar, Paying Agent or Conversion Agent without prior notice to Holders.

 (B)    Duties of the Registrar. The Registrar will keep a record (the “Register”) of the
names and addresses of the Holders, the Notes held by each Holder and the transfer, exchange, repurchase, Redemption and conversion of Notes. Absent manifest error, the entries in the Register will be conclusive and the Company and the Trustee may
treat each Person whose name is recorded as a Holder in the Register as a Holder for all purposes. The Register will be in written form or in any form capable of being converted into written form reasonably promptly. 

(C)    Co-Agents; Company’s Right to Appoint Successor Registrars, Paying
Agents and Conversion Agents. The Company may appoint one or more co-Registrars, co-Paying Agents and co-Conversion Agents,
each of whom will be deemed to be a Registrar, Paying Agent or Conversion Agent, as applicable, under this Indenture. Subject to Section 2.06(A), the Company may change any Registrar, Paying Agent or Conversion Agent
(including appointing itself or any of its Subsidiaries to act in such capacity) without notice to any Holder. The Company will notify the Trustee (and, upon request, any Holder) of the name and address of each Note Agent, if any, not a party to
this Indenture and will enter into an appropriate agency agreement with each such Note Agent, which agreement will implement the provisions of this Indenture that relate to such Note Agent. 

(D)    Initial Appointments. The Company appoints the Trustee as the initial Paying Agent, the initial Registrar
and the initial Conversion Agent. 
 Section 2.07. PAYING AGENT AND
CONVERSION AGENT TO HOLD PROPERTY IN TRUST. 

The Company will require each Paying Agent or Conversion Agent that is not the Trustee 

  
 - 18 - 










Table of Contents




 
to agree in writing that such Note Agent will (A) hold in trust for the benefit of Holders or the Trustee all money and other property held by such Note Agent for payment or delivery due on
the Notes; and (B) notify the Trustee of any default by the Company in making any such payment or delivery. The Company, at any time, may, and the Trustee, while any Default continues, may, require a Paying Agent or Conversion Agent to pay or
deliver, as applicable, all money and other property held by it to the Trustee, after which payment or delivery, as applicable, such Note Agent (if not the Company or any of its Subsidiaries) will have no further liability for such money or
property. If the Company or any of its Subsidiaries acts as Paying Agent or Conversion Agent, then (A) it will segregate and hold in a separate trust fund for the benefit of the Holders or the Trustee all money and other property held by it as
Paying Agent or Conversion Agent; and (B) references in this Indenture or the Notes to the Paying Agent or Conversion Agent holding cash or other property, or to the delivery of cash or other property to the Paying Agent or Conversion Agent, in
each case for payment or delivery to any Holders or the Trustee or with respect to the Notes, will be deemed to refer to cash or other property so segregated and held separately, or to the segregation and separate holding of such cash or other
property, respectively. Upon the occurrence of any event pursuant to clause (ix) or (x) of Section 7.01(A) with respect to the Company (or with respect to any Subsidiary of the Company acting as
Paying Agent or Conversion Agent), the Trustee will serve as the Paying Agent or Conversion Agent, as applicable, for the Notes. 
 
Section 2.08. HOLDER LISTS. 
 If the Trustee is not the Registrar, the Company will furnish to
the Trustee, no later than seven (7) Business Days before each Interest Payment Date, and at such other times as the Trustee may request, a list, in such form and as of such date or time as the Trustee may reasonably require, of the names and
addresses of the Holders. 
 Section 2.09. LEGENDS. 

(A)    Global Note Legend. Each Global Note will bear the Global Note Legend (or any similar legend, not
inconsistent with this Indenture, required by the Depositary for such Global Note). 
 (B)    Non-Affiliate Legend. Each Note that is not an Affiliate Note will bear the Non-Affiliate Legend. 

(C)    Restricted Note Legend. Subject to Section 2.12, 

(i)    each Note that is a Transfer-Restricted Security will bear the Restricted Note Legend; and 

(ii)    if a Note is issued in exchange for, in substitution of, or to effect a partial conversion of,
another Note (such other Note being referred to as the “old Note” for purposes of this Section 2.09(C)(ii)), including pursuant to Section 2.10(B), 2.10(C), 2.11 or 2.13, then such
Note will bear the Restricted Note Legend if such old Note bore the Restricted Note Legend at the time of such exchange or substitution, or on the related Conversion Date with respect to such conversion, as applicable; provided,
however, that 

  
 - 19 - 










Table of Contents




 
such Note need not bear the Restricted Note Legend if such Note does not constitute a Transfer-Restricted Security immediately after such exchange or substitution, or as of such Conversion Date,
as applicable. 
 (D)    Other Legends. A Note may bear any other legend or text, not inconsistent with this
Indenture, as may be required by applicable law or by any securities exchange or automated quotation system on which such Note is traded or quoted. 

(E)    Acknowledgment and Agreement by the Holders. A Holder’s acceptance of any Note bearing any legend
required by this Section 2.09 will constitute such Holder’s acknowledgment of, and agreement to comply with, the restrictions set forth in such legend. 

(F)    Restricted Stock Legend. 

(i)    Each Conversion Share will bear the Restricted Stock Legend if the Note upon the conversion of which
such Conversion Share was issued was (or would have been had it not been converted) a Transfer-Restricted Security at the time such Conversion Share was issued; provided, however, that such Conversion Share need not bear the Restricted
Stock Legend if the Company determines, in its reasonable discretion, that such Conversion Share need not bear the Restricted Stock Legend. 

(ii)    Notwithstanding anything to the contrary in this Section 2.09(F), a
Conversion Share need not bear a Restricted Stock Legend if such Conversion Share is issued in an uncertificated form that does not permit affixing legends thereto, provided the Company takes measures (including the assignment thereto of a
“restricted” CUSIP number) that it reasonably deems appropriate to enforce the transfer restrictions referred to in the Restricted Stock Legend. 

Section 2.10. TRANSFERS AND EXCHANGES; CERTAIN
TRANSFER RESTRICTIONS. 
 (A)    Provisions Applicable to All Transfers and
Exchanges. 
 (i)    Subject to this Section 2.10, Physical Notes and
beneficial interests in Global Notes may be transferred or exchanged from time to time and the Registrar will record each such transfer or exchange in the Register. 

(ii)    Each Note issued upon transfer or exchange of any other Note (such other Note being referred to as
the “old Note” for purposes of this Section 2.10(A)(ii)) or portion thereof in accordance with this Indenture will be the valid obligation of the Company, evidencing the same indebtedness, and entitled to the same
benefits under this Indenture, as such old Note or portion thereof, as applicable. 
 (iii)    The
Company, the Trustee and the Note Agents will not impose any service charge on any Holder for any transfer, exchange or conversion of Notes, but the Company, the Trustee, the Registrar and the Conversion Agent may require payment of a sum sufficient
to cover any transfer tax or similar governmental charge that may be imposed in connection with any transfer, exchange or conversion of Notes, other than exchanges pursuant to Section 2.11, 2.17 or 8.05 not involving
any transfer.

Table of Contents




 (iv)    Notwithstanding anything to the contrary in this
Indenture or the Notes, a Note may not be transferred or exchanged in part unless the portion to be so transferred or exchanged is in an Authorized Denomination. 

(v)    The Trustee will have no obligation or duty to monitor, determine or inquire as to compliance with
any transfer restrictions imposed under this Indenture or applicable law with respect to any Security, other than to require the delivery of such certificates or other documentation or evidence as expressly required by this Indenture and to examine
the same to determine substantial compliance as to form with the requirements of this Indenture. 

(vi)    Each Note issued upon transfer of, or in exchange for, another Note will bear each legend, if any,
required by Section 2.09. 
 (vii)    Upon satisfaction of the requirements of
this Indenture to effect a transfer or exchange of any Note, the Company will cause such transfer or exchange to be effected as soon as reasonably practicable but in no event later than the second (2nd) Business Day after the date of such
satisfaction. 
 (viii)    For the avoidance of doubt, and subject to the terms of this Indenture, as
used in this Section 2.10, an “exchange” of a Global Note or a Physical Note includes (x) an exchange effected for the sole purpose of removing any Restricted Note Legend affixed to such Global Note or
Physical Note; and (y) if such Global Note or Physical Note is identified by a “restricted” CUSIP number, an exchange effected for the sole purpose of causing such Global Note or Physical Note to be identified by an
“unrestricted” CUSIP number. 
 (B)    Transfers and Exchanges of Global Notes. 

(i)    Subject to the immediately following sentence, no Global Note may be transferred or exchanged in
whole except (x) by the Depositary to a nominee of the Depositary; (y) by a nominee of the Depositary to the Depositary or to another nominee of the Depositary; or (z) by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary. No Global Note (or any portion thereof) may be transferred to, or exchanged for, a Physical Note; provided, however, that a Global Note will be exchanged, pursuant to customary procedures, for
one or more Physical Notes if: 
 (1)    (x) the Depositary notifies the Company or the Trustee that the
Depositary is unwilling or unable to continue as depositary for such Global Note or (y) the Depositary ceases to be a “clearing agency” registered under Section 17A of the Exchange Act and, in each case, the Company fails to
appoint a successor Depositary within ninety (90) days of such notice or cessation; 
 (2)    an
Event of Default has occurred and is continuing and the Company, the Trustee or the Registrar has received a written request from the Depositary, or from a holder of a beneficial interest in such Global Note, to exchange such Global Note or
beneficial interest, as applicable, for one or more Physical Notes; or 

  
 - 21 - 










Table of Contents




 (3)    the Company, in its sole discretion, permits the
exchange of any beneficial interest in such Global Note for one or more Physical Notes at the request of the owner of such beneficial interest. 

(ii)    Upon satisfaction of the requirements of this Indenture to effect a transfer or exchange of any
Global Note (or any portion thereof): 
 (1)    the Trustee will reflect any resulting decrease of the
principal amount of such Global Note by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such Global Note (and, if such notation results in such Global Note having a principal amount of zero, the
Company may (but is not required to) instruct the Trustee to cancel such Global Note pursuant to Section 2.15); 

(2)    if required to effect such transfer or exchange, then the Trustee will reflect any resulting
increase of the principal amount of any other Global Note by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such other Global Note; 

(3)    if required to effect such transfer or exchange, then the Company will issue, execute and deliver,
and the Trustee will authenticate, in each case in accordance with Section 2.02, a new Global Note bearing each legend, if any, required by Section 2.09; and 

(4)    if such Global Note (or such portion thereof), or any beneficial interest therein, is to be
exchanged for one or more Physical Notes, then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in
Authorized Denominations and have an aggregate principal amount equal to the principal amount of such Global Note to be so exchanged; (y) are registered in such name(s) as the Depositary specifies (or as otherwise determined pursuant to
customary procedures); and (z) bear each legend, if any, required by Section 2.09. 

(iii)    Each transfer or exchange of a beneficial interest in any Global Note will be made in accordance
with the Depositary Procedures. 
 (C)    Transfers and Exchanges of Physical Notes. 

(i)    Subject to this Section 2.10, a Holder of a Physical Note may
(x) transfer such Physical Note (or any portion thereof in an Authorized Denomination) to one or more other Person(s); (y) exchange such Physical Note (or any portion thereof in an Authorized Denomination) for one or more other Physical Notes
in Authorized Denominations having an aggregate principal amount equal to the aggregate principal amount of the Physical Note (or portion thereof) to be so exchanged; and (z) if then permitted by the Depositary Procedures, and provided such
Physical Note is not an

Affiliate Note, transfer such Physical Note (or any portion thereof in an Authorized Denomination) in exchange for a beneficial interest in one or more Global Notes; provided,
however, that, to effect any such transfer or exchange, such Holder must: 
 (1)    surrender such
Physical Note to be transferred or exchanged to the office of the Registrar, together with any endorsements or transfer instruments reasonably required by the Company, the Trustee or the Registrar; and 

(2)    deliver such certificates, documentation or evidence as may be required pursuant to
Section 2.10(D). 
 (ii)    Upon the satisfaction of the requirements of this
Indenture to effect a transfer or exchange of any Physical Note (such Physical Note being referred to as the “old Physical Note” for purposes of this Section 2.10(C)(ii)) of a Holder (or any portion of such old
Physical Note in an Authorized Denomination): 
 (1)    such old Physical Note will be promptly cancelled
pursuant to Section 2.15; 
 (2)    if such old Physical Note is to be so
transferred or exchanged only in part, then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in
Authorized Denominations and have an aggregate principal amount equal to the principal amount of such old Physical Note not to be so transferred or exchanged; (y) are registered in the name of such Holder; and (z) bear each legend, if any,
required by Section 2.09; 
 (3)    in the case of a transfer: 

(a)    to the Depositary or a nominee thereof that will hold its interest in such old Physical Note (or
such portion thereof) to be so transferred in the form of one or more Global Notes, the Trustee will reflect an increase of the principal amount of one or more existing Global Notes by notation on the “Schedule of Exchanges of Interests in the
Global Note” forming part of such Global Note(s), which increase(s) are in Authorized Denominations and aggregate to the principal amount to be so transferred, and which Global Note(s) bear each legend, if any, required by
Section 2.09; provided, however, that if such transfer cannot be so effected by notation on one or more existing Global Notes (whether because no Global Notes bearing each legend, if any, required by
Section 2.09 then exist, because any such increase will result in any Global Note having an aggregate principal amount exceeding the maximum aggregate principal amount permitted by the Depositary or otherwise), then the
Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Global Notes that (x) are in Authorized Denominations and have an aggregate
principal amount equal to the principal amount to be so transferred; and (y) bear each legend, if any, required by Section 2.09; and 

  
 - 23 - 










Table of Contents




 (b)    to a transferee that will hold its interest in
such old Physical Note (or such portion thereof) to be so transferred in the form of one or more Physical Notes, the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with
Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount to be so transferred; (y) are registered in the name of such
transferee; and (z) bear each legend, if any, required by Section 2.09; and 

(4)    in the case of an exchange, the Company will issue, execute and deliver, and the Trustee will
authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount to be so exchanged;
(y) are registered in the name of the Person to whom such old Physical Note was registered; and (z) bear each legend, if any, required by Section 2.09. 

(D)    Requirement to Deliver Documentation and Other Evidence. If a Holder of any Note that is identified by a
“restricted” CUSIP number or that bears a Restricted Note Legend or is a Transfer-Restricted Security requests to: 

(i)    cause such Note to be identified by an “unrestricted” CUSIP number; 

(ii)    remove such Restricted Note Legend; or 

(iii)    register the transfer of such Note to the name of another Person, 

then the Company, the Trustee and the Registrar may refuse to effect such identification, removal or transfer, as applicable, unless there is delivered to the
Company, the Trustee and the Registrar such certificates or other documentation or evidence as the Company, the Trustee and the Registrar may reasonably require to determine that such identification, removal or transfer, as applicable, complies with
the Securities Act and other applicable securities laws; provided, however, that no such certificates, documentation or evidence need be so delivered on and after the Free Trade Date with respect to such Note unless the Company
determines, in its reasonable discretion, that such Note is not eligible to be offered, sold or otherwise transferred pursuant to Rule 144 or otherwise without any requirements as to volume, manner of sale, availability of current public information
or notice under the Securities Act. 
 (E)    Transfers of Notes Subject to Redemption, Repurchase or Conversion.
Notwithstanding anything to the contrary in this Indenture or the Notes, the Company, the Trustee and the Registrar will not be required to register the transfer of or exchange any Note that (i) has been surrendered for conversion, except to
the extent that any portion of such Note is not subject to conversion; or (ii) is subject to a Fundamental Change Repurchase Notice validly delivered, and not withdrawn, pursuant to Section 4.02(F), except to the
extent that any portion of such Note is not subject to such notice or the Company fails to pay the applicable

Fundamental Change Repurchase Price when due; or (iii) has been selected for Redemption pursuant to a Redemption Notice, except to the extent that the Company fails to pay the applicable
Redemption Price when due. 
 Section 2.11. EXCHANGE AND CANCELLATION
OF NOTES TO BE CONVERTED OR TO BE REPURCHASED PURSUANT TO A
REPURCHASE UPON FUNDAMENTAL CHANGE OR REDEMPTION. 

(A)    Partial Conversions of Physical Notes and Partial Repurchases of Physical Notes Pursuant to a Repurchase Upon
Fundamental Change. If only a portion of a Physical Note of a Holder is to be converted pursuant to Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change, then, as soon as reasonably practicable after such Physical
Note is surrendered for such conversion or repurchase, as applicable, the Company will cause such Physical Note to be exchanged, pursuant and subject to Section 2.10(C), for (i) one or more Physical Notes that are in
Authorized Denominations and have an aggregate principal amount equal to the principal amount of such Physical Note that is not to be so converted or repurchased, as applicable, and deliver such Physical Note(s) to such Holder; and (ii) a
Physical Note having a principal amount equal to the principal amount to be so converted or repurchased, as applicable, which Physical Note will be converted or repurchased, as applicable, pursuant to the terms of this Indenture; provided,
however, that the Physical Note referred to in this clause (ii) need not be issued at any time after which such principal amount subject to such conversion or repurchase, as applicable, is deemed to cease to be outstanding
pursuant to Section 2.18. 
 (B)    Cancellation of Notes that Are Converted and Notes that
Are Repurchased Pursuant to a Repurchase Upon Fundamental Change or Redemption. 
 (i)    Physical
Notes. If a Physical Note (or any portion thereof that has not theretofore been exchanged pursuant to Section 2.11(A)) of a Holder is to be converted pursuant to Article 5 or repurchased pursuant to a Repurchase
Upon Fundamental Change or Redemption, then, promptly after the later of the time such Physical Note (or such portion) is deemed to cease to be outstanding pursuant to Section 2.18 and the time such Physical Note is
surrendered for such conversion or repurchase, as applicable, (1) such Physical Note will be cancelled pursuant to Section 2.15; and (2) in the case of a partial conversion or repurchase, as applicable, the
Company will issue, execute and deliver to such Holder, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an
aggregate principal amount equal to the principal amount of such Physical Note that is not to be so converted or repurchased, as applicable; (y) are registered in the name of such Holder; and (z) bear each legend, if any, required by
Section 2.09. 
 (ii)    Global Notes. If a Global Note (or any portion
thereof) is to be converted pursuant to Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change or Redemption, then, promptly after the time such Note (or such portion) is deemed to cease to be outstanding pursuant to
Section 2.18, the Trustee will reflect a decrease of the principal amount of such Global Note in an amount equal to the principal amount of such Global Note to be so converted or repurchased, as applicable, by notation on
the “Schedule of Exchanges of Interests in the Global Note” forming part of such Global Note (and, if the principal amount of such Global Note is zero following such notation, cancel such Global Note pursuant to
Section 2.15).

 Section 2.12. REMOVAL OF
TRANSFER RESTRICTIONS. 
 Without limiting the generality of any other provision of this Indenture
(including Section 3.04), the Restricted Note Legend affixed to any Note will be deemed, pursuant to this Section 2.12 and the footnote to such Restricted Note Legend, to be removed therefrom upon
the Company’s delivery to the Trustee of notice, signed on behalf of the Company by one (1) of its Officers, to such effect (and, for the avoidance of doubt, such notice need not be accompanied by an Officer’s Certificate or an
Opinion of Counsel in order to be effective to cause such Restricted Note Legend to be deemed to be removed from such Note). If such Note bears a “restricted” CUSIP or ISIN number at the time of such delivery, then, upon such delivery,
such Note will be deemed, pursuant to this Section 2.12 and the footnotes to the CUSIP and ISIN numbers set forth on the face of the certificate representing such Note, to thereafter bear the “unrestricted” CUSIP
and ISIN numbers identified in such footnotes; provided, however, that if such Note is a Global Note and the Depositary thereof requires a mandatory exchange or other procedure to cause such Global Note to be identified by
“unrestricted” CUSIP and ISIN numbers in the facilities of such Depositary, then (i) the Company will effect such exchange or procedure as soon as reasonably practicable; and (ii) for purposes of
Section 3.04 and the definition of Freely Tradable, such Global Note will not be deemed to be identified by “unrestricted” CUSIP and ISIN numbers until such time as such exchange or procedure is effected. 

Section 2.13. REPLACEMENT NOTES. 

If a Holder of any Note claims that such Note has been mutilated, lost, destroyed or wrongfully taken, then the Company will issue, execute and
deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, a replacement Note upon surrender to the Trustee of such mutilated Note, or upon delivery to the Trustee of evidence of such loss,
destruction or wrongful taking reasonably satisfactory to the Trustee and the Company. In the case of a lost, destroyed or wrongfully taken Note, the Company and the Trustee may require the Holder thereof to provide such security or indemnity that
is reasonably satisfactory to the Company and the Trustee to protect the Company and the Trustee from any loss that any of them may suffer if such Note is replaced. 

Every replacement Note issued pursuant to this Section 2.13 will be an additional obligation of the Company and will
be entitled to all of the benefits of this Indenture equally and ratably with all other Notes issued under this Indenture. 

Section 2.14. REGISTERED HOLDERS; CERTAIN RIGHTS
WITH RESPECT TO GLOBAL NOTES. 
 Only the Holder of a Note
will have rights under this Indenture as the owner of such Note. Without limiting the generality of the foregoing, Depositary Participants will have no rights as such under this Indenture with respect to any Global Note held on their behalf by the
Depositary or its nominee, or by the Trustee as its custodian, and the Company, the Trustee and the Note Agents, and their respective agents, may treat the Depositary as the absolute owner of such Global Note for all purposes whatsoever;
provided, however, that (A) the Holder of any 

  
 - 26 - 










Table of Contents




 
Global Note may grant proxies and otherwise authorize any Person, including Depositary Participants and Persons that hold interests in Notes through Depositary Participants, to take any action
that such Holder is entitled to take with respect to such Global Note under this Indenture or the Notes; and (B) the Company and the Trustee, and their respective agents, may give effect to any written certification, proxy or other
authorization furnished by the Depositary. 
 Section 2.15. CANCELLATION. 

Without limiting the generality of Section 3.08, the Company may at any time deliver Notes to the Trustee for
cancellation. The Registrar, the Paying Agent and the Conversion Agent will forward to the Trustee each Note duly surrendered to them for transfer, exchange, payment or conversion. The Trustee will promptly cancel all Notes so surrendered to it in
accordance with its customary procedures. Without limiting the generality of Section 2.03(B), the Company may not originally issue new Notes to replace Notes that it has paid or that have been cancelled upon transfer,
exchange, payment or conversion. 
 Section 2.16. NOTES HELD BY
THE COMPANY OR ITS AFFILIATES. 
 Without limiting the
generality of Sections 3.08 and 2.18, in determining whether the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or any of its Affiliates
(including, for the avoidance of doubt, Affiliate Notes owned by any of the Company’s Affiliates) will be deemed not to be outstanding; provided, however, that, for purposes of determining whether the Trustee is protected in
relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded. 

Section 2.17. TEMPORARY NOTES. 

Until definitive Notes are ready for delivery, the Company may issue, execute and deliver, and the Trustee will authenticate, in each case in
accordance with Section 2.02, temporary Notes. Temporary Notes will be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes. The Company will
promptly prepare, issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, definitive Notes in exchange for temporary Notes. Until so exchanged, each temporary Note will
in all respects be entitled to the same benefits under this Indenture as definitive Notes. 
 Section 2.18.
OUTSTANDING NOTES. 
 (A)    Generally. The Notes that are outstanding at any
time will be deemed to be those Notes that, at such time, have been duly executed and authenticated, excluding those Notes (or portions thereof) that have theretofore been (i) cancelled by the Trustee or delivered to the Trustee for
cancellation in accordance with Section 2.15; (ii) assigned a principal amount of zero by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of any a Global Note representing such
Note; (iii) paid in full (including upon conversion) in accordance with this Indenture; or (iv) deemed to cease to be outstanding to the extent provided in, and subject to, clause (B), (C) or (D) of this
Section 2.18.

 (B)    Replaced Notes. If a Note is replaced pursuant to
Section 2.13, then such Note will cease to be outstanding at the time of its replacement, unless the Trustee and the Company receive proof reasonably satisfactory to them that such Note is held by a “bona fide
purchaser” under applicable law. 
 (C)    Maturing Notes and Notes Called for Redemption or Subject to
Repurchase. If, on a Redemption Date, a Fundamental Change Repurchase Date or the Maturity Date, the Paying Agent holds money sufficient to pay the aggregate Redemption Price, Fundamental Change Repurchase Price or principal amount,
respectively, together, in each case, with the aggregate interest, in each case due on such date, then (unless there occurs a Default in the payment of any such amount) (i) the Notes (or portions thereof) to be redeemed or repurchased, or that
mature, on such date will be deemed, as of such date, to cease to be outstanding, except to the extent provided in Section 4.02(D), 4.03(E) or 5.02(D); and (ii) the rights of the Holders of such Notes (or
such portions thereof), as such, will terminate with respect to such Notes (or such portions thereof), other than the right to receive the Redemption Price, Fundamental Change Repurchase Price or principal amount, as applicable, of, and accrued and
unpaid interest on, such Notes (or such portions thereof), in each case as provided in this Indenture. 

(D)    Notes to Be Converted. At the Close of Business on the Conversion Date for any Note (or any portion thereof)
to be converted, such Note (or such portion) will (unless there occurs a Default in the delivery of the Conversion Consideration or interest due, pursuant to Section 5.03(A) or Section 5.02(D),
upon such conversion) be deemed to cease to be outstanding, except to the extent provided in Section 5.02(D) or Section 5.08. 

(E)    Cessation of Accrual of Interest. Except as provided in Section 4.02(D),
4.03(E) or 5.02(D), interest will cease to accrue on each Note from, and including, the date that such Note is deemed, pursuant to this Section 2.18, to cease to be outstanding, unless there occurs a default
in the payment or delivery of any cash or other property due on such Note. 
 Section 2.19.
REPURCHASES BY THE COMPANY. 
 Without limiting the generality of
Sections 2.15 and 3.08, the Company may, from time to time, repurchase Notes in open market purchases or in negotiated transactions or otherwise, whether through private or public tender or exchange offers, cash-settled swaps,
other cash-settled derivatives or private open market repurchases not involving a tender offer with one or more Holders without delivering prior notice to Holders. 

Section 2.20. CUSIP AND ISIN NUMBERS. 

Subject to Section 2.12, the Company may use one or more CUSIP or ISIN numbers to identify any of the Notes, and, if
so, the Company and the Trustee will use such CUSIP or ISIN number(s) in notices to Holders; provided, however, that (i) the Trustee makes no representation as to the correctness or accuracy of any such CUSIP or ISIN number; and
(ii) the effectiveness of any such notice will not be affected by any defect in, or omission of, any such CUSIP or ISIN number. The Company will promptly notify the Trustee of any change in the CUSIP or ISIN number(s) identifying any Notes.

periods under the Exchange Act); provided, however, that the Company need not send to the Trustee any material for which the Company has received, or is seeking in good faith and has not been denied, confidential treatment by the SEC.
Any report that the Company files with or furnishes to the SEC through the EDGAR system (or any successor thereto) will be deemed to be sent to the Trustee at the time such report is so filed or furnished via the EDGAR system (or such successor).
Upon the request of any Holder, the Trustee will provide to such Holder a copy of any report that the Company has sent the Trustee pursuant to this Section 3.02(A), other than a report that is deemed to be sent to the
Trustee pursuant to the preceding sentence. 
 (B)    Trustee’s Disclaimer. The Trustee need not determine
whether the Company has filed or furnished any material via the EDGAR system (or such successor). The sending, filing or furnishing of reports pursuant to Section 3.02(A) will not be deemed to constitute constructive notice
to the Trustee of any information contained, or determinable from information contained, therein, including the Company’s compliance with any of its covenants under this Indenture (as to which the Trustee is entitled to rely exclusively on an

file any report (other than Form 8-K reports) that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (after giving effect to all applicable grace periods
thereunder); or 
 (2)    such Note is not otherwise Freely Tradable, 

then Additional Interest will accrue on such Note for each day during such period on which such failure is continuing or such Note is not
Freely Tradable. 
 (ii)    In addition, Additional Interest will accrue on a Note on each day on which
such Note is not Freely Tradable on or after the De-Legending Deadline Date for such Note. 

(B)    Amount and Payment of Additional Interest. Any Additional Interest that accrues on a Note pursuant to

for the first ninety (90) days on which Additional Interest accrues and, thereafter, at a rate per annum equal to one half of one percent (0.50%) of the principal amount thereof; provided, however, that in no event will Additional
Interest, together with any Special Interest, accrue on any day on a Note at a combined rate per annum that exceeds one half of one percent (0.50%). For the avoidance of doubt, any Additional Interest that accrues on a Note will be in addition to
the Stated Interest that accrues on such Note and, subject to the proviso of the immediately preceding sentence, in addition to any Special Interest that accrues on such Note. 

(C)    Notice of Accrual of Additional Interest; Trustee’s Disclaimer. The Company will send notice to the
Holder of each Note, and to the Trustee, of the commencement and termination of any period in which Additional Interest accrues on such Note. In addition, if Additional Interest accrues on any Note, then, no later than five (5) Business Days
before each date on which such Additional Interest is to be paid, the Company will deliver an Officer’s Certificate to the Trustee and the Paying Agent stating (i) that the Company is obligated to pay Additional Interest on such Note on
such date of payment; and (ii) the amount of such Additional Interest that is payable on such date of payment. The Trustee will have no duty to determine whether any Additional Interest is payable or the amount thereof.

excluding, the Fundamental Change Repurchase Date for such Fundamental Change; provided, however, that if such Fundamental Change Repurchase Date is after a Regular Record Date and on or before the next Interest Payment Date, then
(i) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such Repurchase Upon Fundamental Change, to receive, on or, at the Company’s election, before such Interest Payment Date,
the unpaid interest that would have accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date, if such Fundamental Change
Repurchase Date is before such Interest Payment Date); and (ii) the Fundamental Change Repurchase Price will not include accrued and unpaid interest on such Note to, but excluding, such Fundamental Change Repurchase Date. For the avoidance of
doubt, if an Interest Payment Date is not a Business Day within the meaning of Section 2.05(C) and such Fundamental Change Repurchase Date occurs on the Business Day immediately after such Interest Payment Date, then

(F)    Procedures to Exercise the Fundamental Change Repurchase Right. 

(i)    Delivery of Fundamental Change Repurchase Notice and Notes to Be Repurchased. To exercise its
Fundamental Change Repurchase Right for a Note following a Fundamental Change, the Holder thereof must deliver to the Paying Agent:

Repurchase Date (or such later time as may be required by law), a duly completed, written Fundamental Change Repurchase Notice with respect to such Note; and 

(2)    such Note, duly endorsed for transfer (if such Note is a Physical Note) or by book-entry transfer
(if such Note is a Global Note). 
 The Paying Agent will promptly deliver to the Company a copy of each Fundamental Change Repurchase Notice
that it receives.

repurchased, which must be an Authorized Denomination; and 
 (3)    that such Holder is exercising its
Fundamental Change Repurchase Right with respect to such principal amount of such Note;

is a Global Note, then such Fundamental Change Repurchase Notice must comply with the Depositary Procedures (and any such Fundamental Change Repurchase Notice delivered in compliance with the Depositary Procedures will be deemed to satisfy the
requirements of this Section 4.02(F)). 
 (iii)    Withdrawal of Fundamental
Change Repurchase Notice. A Holder that has delivered a Fundamental Change Repurchase Notice with respect to a Note may withdraw such Fundamental Change Repurchase Notice by delivering a written notice of withdrawal to the Paying Agent at any
time before the Close of Business on the Business Day immediately before the related Fundamental Change Repurchase Date. Such withdrawal notice must state: 

(1)    if such Note is a Physical Note, the certificate number of such Note; 

(2)    the principal amount of such Note to be withdrawn, which must be an Authorized Denomination; and

 (3)    the principal amount of such Note, if any, that remains subject to such Fundamental Change
Repurchase Notice, which must be an Authorized Denomination; 
 provided, however, that if such Note is a Global Note, then
such withdrawal notice must comply with the Depositary Procedures (and any such withdrawal notice delivered in compliance with the Depositary Procedures will be deemed to satisfy the requirements of this Section 4.02(F)).

 Upon receipt of any such withdrawal notice with respect to a Note (or any portion thereof), the Paying Agent will (x) promptly
deliver a copy of such withdrawal notice to the Company; and (y) if such Note is surrendered to the Paying Agent, cause such Note (or such portion thereof in accordance with Section 2.11, treating such Note as having
been then surrendered for partial repurchase in the amount set forth in such withdrawal notice as remaining subject to repurchase) to be returned to the Holder thereof (or, if applicable with respect to any Global Note, cancel any instructions for
book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial interest in such Note in accordance with the Depositary Procedures). 

(G)    Payment of the Fundamental Change Repurchase Price. Without limiting the Company’s obligation to
deposit the Fundamental Change Repurchase Price within the time proscribed by Section 3.01(B), the Company will cause the Fundamental Change Repurchase Price for a Note (or portion thereof) to be repurchased pursuant to a
Repurchase Upon

Fundamental Change to be paid to the Holder thereof on or before the later of (i) the applicable Fundamental Change Repurchase Date; and (ii) the date (x) such Note is delivered to
the Paying Agent (in the case of a Physical Note) or (y) the Depositary Procedures relating to the repurchase, and the delivery to the Paying Agent, of such Holder’s beneficial interest in such Note to be repurchased are complied with (in
the case of a Global Note). For the avoidance of doubt, interest payable pursuant to the proviso to Section 4.02(D) on any Note to be repurchased pursuant to a Repurchase Upon Fundamental Change must be paid pursuant to
such proviso regardless of whether such Note is delivered or such Depositary Procedures are complied with pursuant to the first sentence of this Section 4.02(G). 

(H)    Compliance with Applicable Securities Laws. To the extent applicable, the Company will comply with all
federal and state securities laws in connection with a Repurchase Upon Fundamental Change (including complying with Rules 13e-4 and 14e-1 under the Exchange Act and
filing any required Schedule TO, to the extent applicable) so as to permit effecting such Repurchase Upon Fundamental Change in the manner set forth in this Indenture. 

(I)    Repurchase in Part. Subject to the terms of this Section 4.02, Notes may be
repurchased pursuant to a Repurchase Upon Fundamental Change in part, but only in Authorized Denominations. Provisions of this Section 4.02 applying to the repurchase of a Note in whole will equally apply to the repurchase
of a permitted portion of a Note. 
 Section 4.03. RIGHT OF THE

after December 1, 2023, for a cash purchase price equal to the Redemption Price, but only if the Last Reported Sale Price per share of Common Stock exceeds one hundred and thirty percent (130%) of the Conversion Price on (i) each of at
least twenty (20) Trading Days (whether or not consecutive) during the thirty (30) consecutive Trading Days ending on, and including, the Trading Day immediately before the Redemption Notice Date for such Redemption; and (ii) the
Trading Day immediately before such Redemption Notice Date. For the avoidance of doubt, the calling of any Notes for Redemption will constitute a Make-Whole Fundamental Change pursuant to clause (B) of the definition thereof.

and such acceleration has not been rescinded on or before the Redemption Date (including as a result of the payment of the related Redemption Price, and any related interest pursuant to the proviso to Section 4.03(E), on
such Redemption Date), then (i) the Company may not call for Redemption or otherwise redeem any Notes pursuant to this Section 4.03; and (ii) the Company will cause any Notes theretofore surrendered for such
Redemption to be returned to the Holders thereof (or, if applicable with respect to Global Notes, cancel any instructions for book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial interests in such Notes in

notice is withdrawn in accordance with Section 4.02(F); or (c) the Company fails to pay the Fundamental Change Repurchase Price for such Note in accordance with this Indenture. 

Section 5.02. CONVERSION PROCEDURES. 

(A)    Generally. 

(i)    Global Notes. To convert a beneficial interest in a Global Note, the owner of such beneficial
interest must (1) comply with the Depositary Procedures for converting such beneficial interest (at which time such conversion will become irrevocable); and (2) pay any amounts due pursuant to Section 5.02(D) or
Section 5.02(E). 
 (ii)    Physical Notes. To convert all or a portion
of a Physical Note, the Holder of such Note must (1) complete, manually sign and deliver to the Conversion Agent the conversion notice attached to such Physical Note or a facsimile of such conversion notice; (2) deliver such Physical Note
to the Conversion Agent (at which time such conversion will become irrevocable); (3) furnish any endorsements and transfer documents that the Company or the Conversion Agent may require; and (4) pay any amounts due pursuant to
Section 5.02(D) or Section 5.02(E). 
 (B)    Effect of
Converting a Note. At the Close of Business on the Conversion Date for a Note (or any portion thereof) to be converted, such Note (or such portion) will (unless there occurs a Default in the delivery of the Conversion Consideration or interest
due, pursuant to Section 5.03(A) or 5.02(D), upon such conversion) be deemed to cease to be outstanding (and, for the avoidance of doubt, no Person will be deemed to be a Holder of such Note (or such portion thereof) as of
the Close of Business on such Conversion Date), except to the extent provided in Section 5.02(D). 

(C)    Holder of Record of Conversion Shares. The Person in whose name any share of Common Stock is issuable upon
conversion of any Note will be deemed to become the holder of record of such share as of the Close of Business on the Conversion Date for such conversion. 

(D)    Interest Payable upon Conversion in Certain Circumstances. If the Conversion Date of a Note is after a
Regular Record Date and before the next Interest Payment Date, then (i) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such conversion (and, for the avoidance of doubt,
notwithstanding anything set forth in the proviso to this sentence), to receive, on or, at the Company’s election, before such Interest Payment Date, the unpaid interest that would have accrued on such Note to, but


  
 - 39 -

excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date); and (ii) the Holder surrendering such
Note for conversion must deliver to the Conversion Agent, at the time of such surrender, an amount of cash equal to the amount of such interest referred to in clause (i) above; provided, however, that the Holder surrendering such
Note for conversion need not deliver such cash (w) if the Company has specified a Redemption Date that is after such Regular Record Date and on or before the Business Day immediately after such Interest Payment Date; (x) if such Conversion
Date occurs after the Regular Record Date immediately before the Maturity Date; (y) if the Company has specified a Fundamental Change Repurchase Date that is after such Regular Record Date and on or before the Business Day immediately after
such Interest Payment Date; or (z) to the extent of any overdue interest or interest that has accrued on any overdue interest. For the avoidance of doubt, as a result of, and without limiting the generality of, the foregoing, if a Note is
converted with a Conversion Date that is after the Regular Record Date immediately before the Maturity Date, then the Company will pay, as provided above, the interest that would have accrued on such Note to, but excluding, the Maturity Date. For
the avoidance of doubt, if the Conversion Date of a Note to be converted is on an Interest Payment Date, then the Holder of such Note at the Close of Business on the Regular Record Date immediately before such Interest Payment Date will be entitled
to receive, on such Interest Payment Date, the unpaid interest that has accrued on such Note to, but excluding, such Interest Payment Date, and such Note, when surrendered for conversion, need not be accompanied by any cash amount pursuant to the
first sentence of this Section 5.02(D). 
 (E)    Taxes and Duties. If a Holder
converts a Note, the Company will pay any documentary, stamp or similar issue or transfer tax or duty due on the issue or delivery of any shares of Common Stock upon such conversion; provided, however, that if any tax or duty is due
because such Holder requested such shares to be registered in a name other than such Holder’s name, then such Holder will pay such tax or duty and, until having received a sum sufficient to pay such tax or duty, the Conversion Agent may refuse
to deliver any such shares to be issued in a name other than that of such Holder. 
 (F)    Conversion Agent to
Notify Company of Conversions. If any Note is submitted for conversion to the Conversion Agent or the Conversion Agent receives any notice of conversion with respect to a Note, then the Conversion Agent will promptly (and, in any event, no later
than the date the Conversion Agent receives such Note or notice) notify the Company and the Trustee of such occurrence, together with any other information reasonably requested by the Company, and will cooperate with the Company to determine the
Conversion Date for such Note. 
 Section 5.03. SETTLEMENT UPON
CONVERSION. 
 (A)    Conversion Consideration. 

(i)    Generally. Subject to Section 5.03(A)(ii) and
Section 5.03(A)(iii), the type and amount of consideration (the “Conversion Consideration”) due in respect of each $1,000 principal amount of a Note to be converted will be: 

(1)    a number of shares of Common Stock equal to the Capped Conversion Rate for such conversion; 

  
 - 40 - 










Table of Contents




 (2)    if the Conversion Date for such conversion is
before December 1, 2022 and not during a Qualified Make-Whole Fundamental Change Conversion Period, an amount of cash equal to the Applicable Premium; and 

(3)    if the Conversion Date for such conversion is before the date the Requisite Stockholder Approval is
obtained, cash in an amount equal to the Conversion Limitation Make-Whole Amount. 
 (ii)    Cash in
Lieu of Fractional Shares. If the number of shares of Common Stock deliverable pursuant to Section 5.03(A)(i) upon conversion of any Note is not a whole number, then such number will be rounded down to the nearest whole
number and the Company will deliver, in addition to the other consideration due upon such conversion, cash in lieu of the related fractional share in an amount equal to the product of (1) such fraction and (2) the Last Reported Sale Price
per share of Common Stock on the Conversion Date for such conversion (or, if such Conversion Date is not a Trading Day, the immediately preceding Trading Day). 

(iii)    Conversion of Multiple Notes by a Single Holder. If a Holder converts more than one
(1) Note on a single Conversion Date, then the Conversion Consideration due in respect of such conversion will (in the case of any Global Note, to the extent permitted by, and practicable under, the Depositary Procedures) be computed based on
the total principal amount of Notes converted on such Conversion Date by such Holder. 
 (B)    Delivery of the
Conversion Consideration. Except as set forth in Section 5.05(D), the Company will pay or deliver, as applicable, the Conversion Consideration due upon the conversion of any Note to the Holder on the second (2nd)
Business Day immediately after the Conversion Date for such conversion; provided, however, that if a Note is converted with a Conversion Date that is after the Regular Record Date occurring immediately before the Maturity Date, then,
solely for purposes of such conversion, (x) the Company will pay or deliver, on the Maturity Date (or, if the Maturity Date is not a Business Day, the next Business Day), the Conversion Consideration due upon such conversion; and (y) the
Conversion Date will instead be deemed to be the second (2nd) Business Day immediately before the Maturity Date. 

(C)    Deemed Payment of Principal and Interest; Settlement of Accrued Interest Notwithstanding Conversion. If a
Holder converts a Note, then the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Note, and, except as provided in Section 5.02(D), and without limiting the Company’s
obligation to pay the Applicable Premium in connection with the conversion of any Note, the Company’s delivery of the Conversion Consideration due in respect of such conversion will be deemed to fully satisfy and discharge the Company’s
obligation to pay the principal of, and accrued and unpaid interest, if any, on, such Note to, but excluding the Conversion Date. As a result, except as provided in Section 5.02(D), any accrued and unpaid interest on a
converted Note will be deemed to be paid in full rather than cancelled, extinguished or forfeited. 
 Section 5.04.
RESERVE AND STATUS OF COMMON STOCK ISSUED UPON CONVERSION. 

(A)    Stock Reserve. At all times when any Notes are outstanding, the Company will


  
 - 41 - 










Table of Contents




 
reserve (out of its authorized but unissued shares of Common Stock that are not reserved for other purposes) a number of shares of Common Stock sufficient to permit the conversion of all
then-outstanding Notes, assuming the Conversion Rate is increased by the maximum amount pursuant to which the Conversion Rate may be increased pursuant to Section 5.07. 

(B)    Status of Conversion Shares; Listing. Each Conversion Share delivered upon conversion of any Note will be a
newly issued or treasury share (except that any Conversion Share delivered by a designated financial institution pursuant to Section 5.08 need not be a newly issued or treasury share) and will be duly and validly issued,
fully paid, non-assessable, free from preemptive rights and free of any lien or adverse claim (except to the extent of any lien or adverse claim created by the action or inaction of the Holder of such Note or
the Person to whom such Conversion Share will be delivered). If the Common Stock is then listed on any securities exchange, or quoted on any inter-dealer quotation system, then the Company will use commercially reasonable efforts to cause each
Conversion Share, when delivered upon conversion of any Note, to be admitted for listing on such exchange or quotation on such system. 
 
Section 5.05. ADJUSTMENTS TO THE CONVERSION RATE. 

(A)    Events Requiring an Adjustment to the Conversion Rate. The Conversion Rate will be adjusted from time to time
as follows: 
 (i)    Stock Dividends, Splits and Combinations. If the Company issues solely
shares of Common Stock as a dividend or distribution on all or substantially all shares of the Common Stock, or if the Company effects a stock split or a stock combination of the Common Stock (in each case excluding an issuance solely pursuant to a
Common Stock Change Event, as to which Section 5.09 will apply), then the Conversion Rate will be adjusted based on the following formula: 
  

					
	CR1 = CR0	 	x	 	 OS1

		 		 	OS0

 where: 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately before the Open of Business on the effective
date of such stock split or stock combination, as applicable;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or effective date, as applicable;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately before the Open of Business on such Ex-Dividend Date or effective date, as applicable, without giving effect to such dividend,
distribution, stock split or stock combination; and
			
	 OS1
	  	 =
	  	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, stock split or stock combination.



  
 - 42 - 










Table of Contents




 For the avoidance of doubt, an adjustment pursuant to this
Section 5.05(A)(i) will become effective as set forth the definition of CR1 in this Section 5.05(A)(i). If any dividend,
distribution, stock split or stock combination of the type described in this Section 5.05(A)(i) is declared or announced, but not so paid or made, then the Conversion Rate will be readjusted, effective as of the date the
Board of Directors determines not to pay such dividend or distribution or to effect such stock split or stock combination, to the Conversion Rate that would then be in effect had such dividend, distribution, stock split or stock combination not been
declared or announced. 
 (ii)    Rights, Options and Warrants. If the Company distributes, to all
or substantially all holders of Common Stock, rights, options or warrants (other than rights issued or otherwise distributed pursuant to a stockholder rights plan, as to which Sections 5.05(A)(iii)(1) and 5.05(F) will apply)
entitling such holders, for a period of not more than sixty (60) calendar days after the record date of such distribution, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last
Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced, then the Conversion Rate will be increased based on
the following formula: 
  

					
	CR1 = CR0	 	x	 	 OS + X

		 		 	OS + Y

 where: 
  

					
	 CR0
	  	=	  	the Conversion Rate in effect immediately before 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;
			
	 OS
	  	=	  	the number of shares of Common Stock outstanding immediately before 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
	  	=	  	a number of shares of Common Stock obtained by dividing (x) the aggregate price payable to exercise such rights, options or warrants by (y) the average of the Last Reported Sale Prices per share of Common Stock for the ten
(10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced.

Table of Contents




 For the avoidance of doubt, an adjustment pursuant to this
Section 5.05(A)(ii) will become effective set forth in the definition of CR1 in this Section 5.05(A)(ii). To the extent such
rights, options or warrants are not so distributed, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the increase to the Conversion Rate for such distribution been made on the basis of only the rights,
options or warrants, if any, actually distributed. In addition, to the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants (including as a result of such rights, options or warrants not being
exercised), the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the increase to the Conversion Rate for such distribution been made on the basis of delivery of only the number of shares of Common Stock
actually delivered upon exercise of such rights, option or warrants. 
 For purposes of this Section 5.05(A)(ii),
in determining whether any rights, options or warrants entitle holders of Common Stock to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices per share of Common Stock
for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date the distribution of such rights, options or warrants is announced, and in determining the aggregate price payable to exercise such
rights, options or warrants, there will be taken into account any consideration the Company receives for such rights, options or warrants and any amount payable on exercise thereof, with the value of such consideration, if not cash, to be determined
by the Board of Directors. 
 (iii)    Spin-Offs and Other Distributed Property. 

(1)    Distributions Other than Spin-Offs. If the Company distributes shares of its Capital Stock,
evidence of its indebtedness or other assets or property of the Company, or rights, options or warrants to acquire Capital Stock of the Company or other securities, to all or substantially all holders of the Common Stock, excluding: 

(u)    dividends, distributions, rights, options or warrants for which an adjustment to the Conversion
Rate is required (or would be required without regard to Section 5.05(C)) pursuant to Section 5.05(A)(i) or 5.05(A)(ii); 

(v)    dividends or distributions paid exclusively in cash for which an adjustment to the Conversion Rate
is required (or would be required without regard to Section 5.05(C)) pursuant to Section 5.05(A)(iv); 

(w)    rights issued or otherwise distributed pursuant to a stockholder rights plan, except to the extent
provided in Section 5.05(F); 
 (x)    Spin-Offs for which an adjustment to
the Conversion Rate is required (or would be required without regard to Section 5.05(C)) pursuant to Section 5.05(A)(iii)(2); 

  
 - 44 - 










Table of Contents




 (y)    a distribution solely pursuant to a tender offer
or exchange offer for shares of Common Stock, as to which Section 5.05(A)(v) will apply; and 

(z)    a distribution solely pursuant to a Common Stock Change Event, as to which
Section 5.09 will apply, 
 then the Conversion Rate will be increased based on the following formula: 

 

					
	CR1 = CR0	 	x	 	
      SP      


		 		 	SP – FMV

 where: 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately before 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;
			
	SP	  	=	  	the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before such
Ex-Dividend Date; and
			
	FMV	  	=	  	the fair market value (as determined by the Board of Directors), as of such Ex-Dividend Date, of the shares of Capital Stock, evidence of indebtedness, assets or property of the Company, or
rights, options or warrants to acquire Capital Stock or other securities, distributed per share of Common Stock pursuant to such distribution;


 provided, however, that if FMV is equal to or greater than SP, then, in lieu
of the foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such distribution, at the same time and on the same terms as holders of Common Stock,
the amount and kind of shares of Capital Stock, evidence of indebtedness, assets or property of the Company, or rights, options or warrants to acquire Capital Stock or other securities, that such Holder would have received if such Holder had owned,
on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect on such record date. 
 For the avoidance of
doubt, an adjustment pursuant to this Section 5.05(A)(iii)(1) will become effective as set forth in the definition of CR1 in this Section 


  
 - 45 - 










Table of Contents




 
5.05(A)(iii)(1). To the extent such distribution is not so paid or made, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the
adjustment been made on the basis of only the distribution, if any, actually made or paid. 

(2)    Spin-Offs. If the Company distributes or dividends shares of Capital Stock of any class or
series, or similar equity interests, of or relating to an Affiliate, a Subsidiary or other business unit of the Company to all or substantially all holders of the Common Stock (other than solely pursuant to (x) a Common Stock Change Event, as
to which Section 5.09 will apply; or (y) a tender offer or exchange offer for shares of Common Stock, as to which Section 5.05(A)(v) will apply), and such Capital Stock or equity interests are
listed or quoted (or will be listed or quoted upon the consummation of the transaction) on a U.S. national securities exchange (a “Spin-Off”), then the Conversion Rate will be increased based
on the following formula: 
  

					
	CR1 = CR0	 	x	 	 FMV + SP

		 		 	      SP      

 where: 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately before the Close of Business on the last Trading Day of the Spin-Off Valuation Period for such
Spin-Off;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Close of Business on the last Trading Day of the Spin-Off Valuation Period;
			
	FMV	  	=	  	the product of (x) the average of the Last Reported Sale Prices per share or unit of the Capital Stock or equity interests distributed in such Spin-Off over the ten
(10) consecutive Trading Day period (the “Spin-Off Valuation Period”) beginning on, and including, the Ex-Dividend Date for such Spin-Off (such average to be determined as if references to Common Stock in the definitions of Last Reported Sale Price, Trading Day and Market Disruption Event were instead references to such Capital Stock or
equity interests); and (y) the number of shares or units of such Capital Stock or equity interests distributed per share of Common Stock in such Spin-Off; and
			
	SP	  	=	  	the average of the Last Reported Sale Prices per share of Common Stock for each Trading Day in the Spin-Off Valuation Period.


 Notwithstanding anything to the contrary in this Section 5.05(A)(iii)(2), if
the Conversion Date for a Note occurs during the Spin-Off Valuation Period for such Spin-Off, then, solely for purposes of determining the Conversion Consideration


  
 - 46 - 










Table of Contents




 
for such conversion, such Spin-Off Valuation Period will be deemed to consist of the Trading Days occurring in the period from, and including, the Ex-Dividend Date for such Spin-Off to, and including, such Conversion Date. 

For the avoidance of doubt, an adjustment pursuant to this Section 5.05(A)(iii)(2) will become effective as set forth
in the definition of CR1 in this Section 5.05(A)(iii)(2). To the extent any dividend or distribution of the type set forth in this
Section 5.05(A)(iii)(2) is declared but not made or paid, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the dividend or
distribution, if any, actually made or paid. 
 (iv)    Cash Dividends or Distributions. If any
cash dividend or distribution is made to all or substantially all holders of Common Stock, then the Conversion Rate will be increased based on the following formula: 
  

					
	CR1 = CR0	 	x	 	     SP    

		 		 	SP - D

 where: 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such dividend or distribution;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;
			
	SP	  	=	  	the Last Reported Sale Price per share of Common Stock on the Trading Day immediately before such Ex-Dividend Date; and
			
	D	  	=	  	the cash amount distributed per share of Common Stock in such dividend or distribution;


 provided, however, that if D is equal to or greater than SP, then, in lieu of
the foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such dividend or distribution, at the same time and on the same terms as holders of
Common Stock, the amount of cash that such Holder would have received if such Holder had owned, on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect on such record date. 

For the avoidance of doubt, an adjustment pursuant to this Section 5.05(A)(iv) will become effective as set forth in
the definition of CR1 in this Section 5.05(A)(iv). To the extent such dividend or distribution is declared but not made or paid, the Conversion Rate will
be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the dividend or distribution, if any, actually made or paid.

 (v)    Tender Offers or Exchange Offers. If the
Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for shares of Common Stock, and the value (determined as of the Expiration Time by the Board of Directors) of the cash and other consideration paid per
share of Common Stock in such tender or exchange offer exceeds the Last Reported Sale Price per share of Common Stock on the Trading Day immediately after the last date (the “Expiration Date”) on which tenders or exchanges may be
made pursuant to such tender or exchange offer (as it may be amended), then the Conversion Rate will be increased based on the following formula: 
  

					
	CR1 = CR0	 	x	 	 AC + (SP x OS1)

		 		 	      SP x OS0

 where: 
  

					
	CR0	  	=	  	the Conversion Rate in effect immediately before the Close of Business on the last Trading Day of the Tender/Exchange Offer Valuation Period for such tender or exchange offer;
			
	CR1	  	=	  	the Conversion Rate in effect immediately after the Close of Business on the last Trading Day of the Tender/Exchange Offer Valuation Period;
			
	AC	  	=	  	the aggregate value (determined as of the time (the “Expiration Time”) such tender or exchange offer expires by the Board of Directors) of all cash and other consideration paid for shares of Common Stock purchased or
exchanged in such tender or exchange offer;
			
	OS0	  	=	  	the number of shares of Common Stock outstanding immediately before the Expiration Time (including all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);
			
	OS1	  	=	  	the number of shares of Common Stock outstanding immediately after the Expiration Time (excluding all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer); and
			
	SP	  	=	  	the average of the Last Reported Sale Prices per share of Common Stock over the ten (10) consecutive Trading Day period (the “Tender/Exchange Offer Valuation Period”) beginning on, and including, the Trading Day
immediately after the Expiration Date;


 provided, however, that the Conversion Rate will in no event be adjusted down pursuant to
this Section 5.05(A)(v), except to the extent provided in the immediately following paragraph. For the avoidance of doubt, an adjustment pursuant to this Section 5.05(A)(v) will become effective as
set forth in the definition of CR1 in this Section 5.05(A)(v). Notwithstanding anything to the contrary in this
Section 5.05(A)(v), if the Conversion

Table of Contents




 
Date for a Note occurs during the Tender/Exchange Offer Valuation Period for such tender or exchange offer, then, solely for purposes of determining the Conversion Consideration for such
conversion, such Tender/Exchange Offer Valuation Period will be deemed to consist of the Trading Days occurring in the period from, and including, the Trading Day immediately after the Expiration Date to, and including, such Conversion Date. 

To the extent such tender or exchange offer is announced but not consummated (including as a result of the Company being precluded from
consummating such tender or exchange offer under applicable law), or any purchases or exchanges of shares of Common Stock in such tender or exchange offer are rescinded, the Conversion Rate will be readjusted to the Conversion Rate that would then
be in effect had the adjustment been made on the basis of only the purchases or exchanges of shares of Common Stock, if any, actually made, and not rescinded, in such tender or exchange offer. 

(B)    No Adjustments in Certain Cases. 

(i)    Where Holders Participate in the Transaction or Event Without Conversion. Notwithstanding
anything to the contrary in Section 5.05(A), the Company will not be obligated to adjust the Conversion Rate on account of a transaction or other event otherwise requiring an adjustment pursuant to
Section 5.05(A) (other than a stock split or combination of the type set forth in Section 5.05(A)(i) or a tender or exchange offer of the type set forth in
Section 5.05(A)(v)) if each Holder participates, at the same time and on the same terms as holders of Common Stock, and solely by virtue of being a Holder of Notes, in such transaction or event without having to convert
such Holder’s Notes and as if such Holder held a number of shares of Common Stock equal to the product of (i) the Conversion Rate in effect on the related record date; and (ii) the aggregate principal amount (expressed in thousands)
of Notes held by such Holder on such date. 
 (ii)    Certain Events. The Company will not be
required to adjust the Conversion Rate except as provided in Section 5.05 or Section 5.07. Without limiting the foregoing, the Company will not be obligated to adjust the Conversion Rate on account
of: 
 (1)    except as otherwise provided in Section 5.05, the sale of shares
of Common Stock for a purchase price that is less than the market price per share of Common Stock or less than the Conversion Price; 

(2)    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 such plan; 

(3)    the issuance of any shares of Common Stock or options or rights to purchase shares of Common Stock
pursuant to any present or future employee, director or consultant benefit plan or program of, or assumed by, the Company or any of its Subsidiaries; 

  
 - 49 - 










Table of Contents




 (4)    the issuance of any shares of Common Stock
pursuant to any option, warrant, right or convertible or exchangeable security of the Company outstanding as of the Issue Date; 

(5)    for a third party tender offer by any party other than a tender offer by the Company or one or more
of its Subsidiaries described in Section 5.05(A)(v); 
 (6)    on account of
share repurchases, including structured or derivative transactions, or transactions pursuant to a share repurchase program approved by the Board of Directors, or otherwise, in each case that are not tender offers of the type described in
Section 5.05(A)(v); 
 (7)    solely a change in the par value of the Common
Stock; or 
 (8)    accrued and unpaid interest on the Notes. 

(C)    Adjustment Deferral. If an adjustment to the Conversion Rate otherwise required by this Article 5
would result in a change of less than one percent (1%) to the Conversion Rate, then, notwithstanding anything to the contrary in this Article 5, the Company may, at its election, defer such adjustment, except that all such deferred
adjustments must be given effect immediately upon the earliest of the following: (i) when all such deferred adjustments would result in a change of at least one percent (1%) to the Conversion Rate; (ii) the Conversion Date of any Note;
(iii) the date a Fundamental Change or Make-Whole Fundamental Change occurs; (iv) the date the Company calls any Notes for Redemption; and (v) June 1, 2025. 

(D)    Adjustments Not Yet Effective. Notwithstanding anything to the contrary in this Indenture or the Notes, if:

 (i)    a Note is to be converted; 

(ii)    the record date, effective date or Expiration Time for any event that requires an adjustment to the
Conversion Rate pursuant to Section 5.05(A) has occurred on or before the Conversion Date for such conversion, but an adjustment to the Conversion Rate for such event has not yet become effective as of such Conversion Date;

 (iii)    the Conversion Consideration due upon such conversion includes any whole shares of Common
Stock; and 
 (iv)    such shares are not entitled to participate in such event (because they were not
held on the related record date or otherwise), 
 then, solely for purposes of such conversion, the Company will, without duplication, give effect to such
adjustment on such Conversion Date. In such case, if the date on which the Company is otherwise required to deliver the consideration due upon such conversion is before the first date on which the amount of such adjustment can be determined, then
the Company will delay the settlement of such conversion until the second (2nd) Business Day after such first date, and such delay will not be a Default under this Indenture or the Notes.

 (E)    Conversion Rate Adjustments where Converting Holders
Participate in the Relevant Transaction or Event. Notwithstanding anything to the contrary in this Indenture or the Notes, if: 

(i)    a Conversion Rate adjustment for any dividend or distribution becomes effective on any Ex-Dividend Date pursuant to Section 5.05(A); 

(ii)    a Note is to be converted; 

(iii)    the Conversion Date for such conversion occurs on or after such
Ex-Dividend Date and on or before the related record date; 

(iv)    the Conversion Consideration due upon such conversion includes any whole shares of Common Stock
based on a Conversion Rate that is adjusted for such dividend or distribution; and 
 (v)    such shares
would be entitled to participate in such dividend or distribution (including pursuant to Section 5.02(C)), 
 then (x) such
Conversion Rate adjustment will not be given effect for such conversion; (y) the shares of Common Stock issuable upon such conversion based on such unadjusted Conversion Rate will not be entitled to participate in such dividend or distribution;
and (z) there will be added, to the Conversion Consideration otherwise due upon such conversion, the same kind and amount of consideration that would have been delivered in such dividend or distribution with respect to such shares of Common
Stock had such shares been entitled to participate in such dividend or distribution. 
 (F)    Stockholder Rights
Plans. If any shares of Common Stock are to be issued upon conversion of any Note and, at the time of such conversion, the Company has in effect any stockholder rights plan, then the Holder of such Note will be entitled to receive, in addition
to, and concurrently with the delivery of, the Conversion Consideration otherwise payable under this Indenture upon such conversion, the rights set forth in such stockholder rights plan, unless, prior to the applicable Conversion Date, such rights
have separated from the Common Stock, in which case, and only in such case, the Conversion Rate will be adjusted pursuant to Section 5.05(A)(iii)(1) on account of such separation as if, at the time of such separation, the
Company had made a distribution of the type referred to in such Section to all holders of the Common Stock, subject to potential readjustment in accordance with the last paragraph of Section 5.05(A)(iii)(1). For the
avoidance of doubt, in all other cases, the issuance of rights pursuant to a stockholder rights plan will not result in an adjustment to the Conversion Rate pursuant Section 5.05(A)(iii)(1). 

(G)    Limitation on Effecting Transactions Resulting in Certain Adjustments. The Company will not engage in or be
a party to any transaction or event that would require the Conversion Rate to be adjusted pursuant to Section 5.05(A) or Section 5.07 to an amount that would result in the Conversion Price per
share of Common Stock being less than the par value per share of Common Stock.

 (H)    Equitable Adjustments to Prices. Whenever any provision of
this Indenture requires the Company to calculate the average of the Last Reported Sale Prices, or any function thereof, over a period of multiple days (including to calculate the Stock Price or an adjustment to the Conversion Rate), the Company will
make proportionate adjustments, if any, to such calculations to account for any adjustment to the Conversion Rate pursuant to Section 5.05(A)(i) that becomes effective, or any event requiring such an adjustment to the
Conversion Rate where the Ex-Dividend Date or effective date, as applicable, of such event occurs, at any time during such period. 

(I)    Calculation of Number of Outstanding Shares of Common Stock. For purposes of
Section 5.05(A), the number of shares of Common Stock outstanding at any time will (i) include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock; and
(ii) exclude shares of Common Stock held in the Company’s treasury (unless the Company pays any dividend or makes any distribution on shares of Common Stock held in its treasury). 

(J)    Calculations. All calculations with respect to the Conversion Rate and adjustments thereto will be made to
the nearest 1/10,000th of a share of Common Stock (with 5/100,000ths rounded upward). 
 (K)    Notice of Conversion
Rate Adjustments. Upon the effectiveness of any adjustment to the Conversion Rate pursuant to Section 5.05(A), the Company will promptly send notice to the Holders, the Trustee and the Conversion Agent containing
(i) a brief description of the transaction or other event on account of which such adjustment was made; (ii) the Conversion Rate in effect immediately after such adjustment; and (iii) the effective time of such adjustment. 

Section 5.06. VOLUNTARY ADJUSTMENTS. 

(A)    Generally. To the extent permitted by law and applicable stock exchange rules, the Company, from time to
time, may (but is not required to) increase the Conversion Rate by any amount if (i) the Board of Directors determines that such increase is either (x) in the best interest of the Company; or (y) advisable to avoid or diminish any
income tax imposed on holders of Common Stock or rights to purchase Common Stock as a result of any dividend or distribution of shares (or rights to acquire shares) of Common Stock or any similar event; (ii) such increase is in effect for a
period of at least twenty (20) Business Days; and (iii) such increase is irrevocable during such period. 

(B)    Notice of Voluntary Increases. If the Board of Directors determines to increase the Conversion Rate pursuant
to Section 5.06(A), then, no later than the first Business Day of the related twenty (20) Business Day period referred to in Section 5.06(A), the Company will send notice to each Holder, the
Trustee and the Conversion Agent of such increase, the amount thereof and the period during which such increase will be in effect.

THE CONVERSION RATE IN CONNECTION WITH A MAKE-WHOLE FUNDAMENTAL CHANGE. 

(A)    Generally. If a Make-Whole Fundamental Change occurs and the Conversion Date for the conversion of a Note

 If such Make-Whole Fundamental Change Effective Date or Stock Price is not set forth in the table above, then:

 (i)    if such Stock Price is between two Stock Prices in the table above or the Make-Whole
Fundamental Change Effective Date is between two dates in the table above, then the number of Additional Shares will be determined by straight-line interpolation between the numbers of Additional Shares set forth for the higher and lower Stock
Prices in the table above or the earlier and later dates in the table above, based on a 365- or 366-day year, as applicable; and 

(ii)    if the Stock Price is greater than $45.00 (subject to adjustment in the same manner as the Stock
Prices set forth in the column headings of the table above are adjusted pursuant to Section 5.07(B)), or less than $3.27 (subject to adjustment in the same manner), per share, then no Additional Shares will be added to the
Conversion Rate. 
 Notwithstanding anything to the contrary in this Indenture or the Notes, in no event will the Conversion Rate be
increased to an amount that exceeds 305.8103 shares of Common Stock per $1,000 principal amount of Notes, which amount is subject to adjustment in the same manner as, and at the same time and for the same events for which, the Conversion Rate is
required to be adjusted pursuant to Section 5.05(A). 
 (B)    Adjustment of Stock Prices
and Number of Additional Shares. The Stock Prices in the first row (i.e., the column headers) of the table set forth in Section 5.07(A) will be adjusted in the same manner as, and at the same time and for the
same events for which, the Conversion Price is adjusted as a result of the operation of Section 5.05(A). The numbers of Additional Shares in the table set forth in Section 5.07(A) will be adjusted
in the same manner as, and at the same time and for the same events for which, the Conversion Rate is adjusted pursuant to Section 5.05(A).

 (C)    Notice of the Occurrence of a Make-Whole Fundamental
Change. If a Make-Whole Fundamental Change occurs pursuant to clause (A) of the definition thereof, then, promptly and in no event later than the Business Day immediately after the Make-Whole Fundamental Change Effective Date with
respect to such Make-Whole Fundamental Change, the Company will notify the Holders of the occurrence of such Make-Whole Fundamental Change and of such Make-Whole Fundamental Change Effective Date, briefly stating the circumstances under which the
Conversion Rate will be increased pursuant to this Section 5.07 in connection with such Make-Whole Fundamental Change. The Company will notify the Holders, the Trustee and the Conversion Agent of each Make-Whole Fundamental
Change occurring pursuant to clause (B) of the definition thereof in accordance with Section 
4.03(F). 
 Section 5.08. EXCHANGE IN LIEU OF
CONVERSION. 
 Notwithstanding anything to the contrary in this Article 5, and subject to the terms of this
Section 5.08, if a Note is submitted for conversion, the Company may elect to arrange to have such Note exchanged in lieu of conversion by a financial institution designated by the Company. To make such election, the
Company must send notice of such election to the Holder of such Note, the Trustee and the Conversion Agent before the Close of Business on the Business Day immediately following the Conversion Date for such Note. If the Company has made such
election, then: 
 (A)    no later than the Business Day immediately following such Conversion Date, the Company must
deliver (or cause the Conversion Agent to deliver) such Note, together with delivery instructions for the Conversion Consideration due upon such conversion (including wire instructions, if applicable), to a financial institution designated by the
Company that has agreed to deliver such Conversion Consideration in the manner and at the time the Company would have had to deliver the same pursuant to this Article 5; 

(B)    if such Note is a Global Note, then (i) such designated institution will send written confirmation to the
Conversion Agent promptly after wiring the cash Conversion Consideration, if any, and delivering any other Conversion Consideration, due upon such conversion to the Holder of such Note; and (ii) the Conversion Agent will as soon as reasonably
practicable thereafter contact such Holder’s custodian with the Depositary to confirm receipt of the same; and 

(C)    such Note will not cease to be outstanding by reason of such exchange in lieu of conversion; 

provided, however, that if such financial institution does not accept such Note or fails to timely deliver such Conversion Consideration, then
the Company will be responsible for delivering such Conversion Consideration in the manner and at the time provided in this Article 5 as if the Company had not elected to make an exchange in lieu of conversion. 

Section 5.09. EFFECT OF COMMON STOCK CHANGE
EVENT. 
 (A)    Generally. If there occurs any: 

(i)    recapitalization, reclassification or change of the Common Stock (other

than (x) changes solely resulting from a subdivision or combination of the Common Stock, (y) a change only in par value or from par value to no par value or no par value to par value
and (z) stock splits and stock combinations that do not involve the issuance of any other series or class of securities); 

(ii)    consolidation, merger, combination or binding or statutory share exchange involving the Company;

 (iii)    sale, lease or other transfer of all or substantially all of the assets of the Company and
its Subsidiaries, taken as a whole, to any Person; or 
 (iv)    other similar event, 

and, as a result of which, the Common Stock is converted into, or is exchanged for, or represents solely the right to receive, other securities, cash or other
property, or any combination of the foregoing (such an event, a “Common Stock Change Event,” and such other securities, cash or property, the “Reference Property,” and the amount and kind of Reference Property that
a holder of one (1) share of Common Stock would be entitled to receive on account of such Common Stock Change Event (without giving effect to any arrangement not to issue or deliver a fractional portion of any security or other property), a
“Reference Property Unit”), then, notwithstanding anything to the contrary in this Indenture or the Notes, 

(1)    from and after the effective time of such Common Stock Change Event, (I) the Conversion
Consideration due upon conversion of any Note will be determined in the same manner as if each reference to any number of shares of Common Stock in this Article 5 (or in any related definitions) were instead a reference to the same number of
Reference Property Units; (II) for purposes of Section 4.03, each reference to any number of shares of Common Stock in such Section (or in any related definitions) will instead be deemed to be a reference to the same
number of Reference Property Units; and (III) for purposes of the definitions of “Fundamental Change” and “Make-Whole Fundamental Change,” references to “Common Stock” and the Company’s “common
equity” will be deemed to refer to the common equity (including depositary receipts representing common equity), if any, forming part of such Reference Property; and 

(2)    for these purposes, the Last Reported Sale Price of any Reference Property Unit or portion thereof
that does not consist of a class of securities will be the fair value of such Reference Property Unit or portion thereof, as applicable, determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars, the face amount
thereof). 
 If the Reference Property consists of more than a single type of consideration to be determined based in part upon any form of
stockholder election, then the composition of the Reference Property Unit will be deemed to be the weighted average of the types and amounts of consideration actually received, per share of Common Stock, by the holders of Common Stock. The Company
will notify Holders of such weighted average as soon as practicable after such determination is made.

 At or before the effective time of such Common Stock Change Event, the Company and the
resulting, surviving or transferee Person (if not the Company) of such Common Stock Change Event (the “Successor Person”) will execute and deliver to the Trustee a supplemental indenture pursuant to
Section 8.01(F), which supplemental indenture will (x) provide for subsequent conversions of Notes in the manner set forth in this Section 5.09; (y) provide for subsequent adjustments to the
Conversion Rate pursuant to Section 5.05(A) in a manner consistent with this Section 5.09; and (z) contain such other provisions, if any, that the Company reasonably determines are appropriate
to preserve the economic interests of the Holders and to give effect to the provisions of this Section 5.09(A). If the Reference Property includes shares of stock or other securities or assets (other than cash) of a Person
other than the Successor Person, then such other Person will also execute such supplemental indenture and such supplemental indenture will contain such additional provisions, if any, that the Company reasonably determines are appropriate to preserve
the economic interests of the Holders. 
 (B)    Notice of Common Stock Change Events. The Company will provide
notice of each Common Stock Change Event to Holders, the Trustee and the Conversion Agent no later than the effective date of such Common Stock Change Event. 

(C)    Compliance Covenant. The Company will not become a party to any Common Stock Change Event unless its terms
are consistent with this Section 5.09. 
 Article 6. SUCCESSORS 

Section 6.01. WHEN THE COMPANY MAY MERGE,
ETC. 
 (A)    Generally. The Company will not consolidate with or merge with or into, or
(directly, or indirectly through one or more of its Subsidiaries) sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to
another Person (a “Business Combination Event”), unless: 
 (i)    the resulting,
surviving or transferee Person either (x) is the Company or (y) if not the Company, is a corporation (the “Successor Corporation”) duly organized and existing under the laws of the United States of America, any State
thereof or the District of Columbia that expressly assumes (by executing and delivering to the Trustee, at or before the effective time of such Business Combination Event, a supplemental indenture pursuant to
Section 8.01(E)) all of the Company’s obligations under this Indenture and the Notes; and 

(ii)    immediately after giving effect to such Business Combination Event, no Default or Event of Default
will have occurred and be continuing. 
 (B)    Delivery of Officer’s Certificate and Opinion of Counsel to the
Trustee. Before the effective time of any Business Combination Event, the Company will deliver to the Trustee an Officer’s Certificate and Opinion of Counsel, each stating that (i) such Business Combination Event (and, if applicable,
the related supplemental indenture) comply with Section 6.01(A); and (ii) all conditions precedent to such Business Combination Event provided in this Indenture have been satisfied.

Section 6.01, the Successor Corporation (if not the Company) will succeed to, and may exercise every right and power of, the Company under this Indenture and the Notes with the same effect as if such Successor Corporation
had been named as the Company in this Indenture and the Notes, and, except in the case of a lease, the predecessor Company will be discharged from its obligations under this Indenture and the Notes.

Section 7.01(A) will constitute an Event of Default regardless of the cause thereof or whether voluntary or involuntary or 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 7.02. ACCELERATION. 

(A)    Automatic Acceleration in Certain Circumstances. If an Event of Default set forth in
Section 7.01(A)(ix) or 7.01(A)(x) occurs with respect to the Company (and not solely with respect to a Significant Subsidiary of the Company), then the principal amount of, and all accrued and unpaid interest, and
any Applicable Premium that has become due, on, all of the Notes then outstanding will immediately become due and payable without any further action or notice by any Person. 

(B)    Optional Acceleration. Subject to Section 7.03, if an Event of Default (other than
an Event of Default set forth in Section 7.01(A)(ix) or 7.01(A)(x) with respect to the Company and not solely with respect to a Significant Subsidiary of the Company) occurs and is continuing, then the Trustee, by
notice to the Company, or Holders of at least twenty five percent (25%) of the aggregate principal amount of Notes then outstanding, by notice to the Company and the Trustee, may declare the principal amount of, and all accrued and unpaid interest,
and any Applicable Premium that has become due, on, all of the Notes then outstanding to become due and payable immediately. 

(C)    Rescission of Acceleration. Notwithstanding anything to the contrary in this Indenture or the Notes, the
Holders of a majority in aggregate principal amount of the Notes then outstanding, by notice to the Company and the Trustee, may, on behalf of all Holders, rescind any acceleration of the Notes and its consequences if (i) such rescission would
not conflict with any judgment or decree of a court of competent jurisdiction; and (ii) all existing Events of Default (except the non-payment of principal of, or interest or the Applicable Premium, on,
the Notes that has become due solely because of such acceleration) have been cured or waived. No such rescission will affect any subsequent Default or impair any right consequent thereto.

Indenture or the Notes, the Company may elect that the sole remedy for any Event of Default (a “Reporting Event of Default”) pursuant to Section 7.01(A)(vi) arising from the Company’s failure to comply
with Section 3.02 will, for each of the first one hundred eighty (180) calendar days on which a Reporting Event of Default has occurred and is continuing, consist exclusively of the accrual of Special Interest on the
Notes. If the Company has made such an election, then (i) the Notes will be subject to acceleration pursuant to Section 7.02 on account of the relevant

Table of Contents




 
Reporting Event of Default from, and including, the one hundred eighty first (181st) calendar day on which a Reporting Event of Default has occurred and is continuing or if the Company fails to
pay any accrued and unpaid Special Interest when due; and (ii) Special Interest will cease to accrue on any Notes from, and including, such one hundred eighty first (181st) calendar day (it being understood that interest on any defaulted
Special Interest will nonetheless accrue pursuant to Section 2.05(B)). 
 (B)    Amount and
Payment of Special Interest. Any Special Interest that accrues on a Note pursuant to Section 7.03(A) will be payable on the same dates and in the same manner as the Stated Interest on such Note and will accrue at a rate
per annum equal to one quarter of one percent (0.25%) of the principal amount thereof for the first ninety (90) days on which Special Interest accrues and, thereafter, at a rate per annum equal to one half of one percent (0.50%) of the
principal amount thereof; provided, however, that in no event will Special Interest, together with any Additional Interest, accrue on any day on a Note at a combined rate per annum that exceeds one half of one percent (0.50%). For the
avoidance of doubt, any Special Interest that accrues on a Note will be in addition to the Stated Interest that accrues on such Note and, subject to the proviso of the immediately preceding sentence, in addition to any Additional Interest that
accrues on such Note. 
 (C)    Notice of Election. To make the election set forth in
Section 7.03(A), the Company must send to the Holders, the Trustee and the Paying Agent, before the date on which each Reporting Event of Default first occurs, a notice that (i) briefly describes the report(s) that the
Company failed to file with or furnish to the SEC; (ii) states that the Company is electing that the sole remedy for such Reporting Event of Default consist of the accrual of Special Interest; and (iii) briefly describes the periods during
which and rate at which Special Interest will accrue and the circumstances under which the Notes will be subject to acceleration on account of such Reporting Event of Default. 

(D)    Notice to Trustee and Paying Agent; Trustee’s Disclaimer. If Special Interest accrues on any Note,
then, no later than five (5) Business Days before each date on which such Special Interest is to be paid, the Company will deliver an Officer’s Certificate to the Trustee and the Paying Agent stating (i) that the Company is obligated
to pay Special Interest on such Note on such date of payment; and (ii) the amount of such Special Interest that is payable on such date of payment. The Trustee will have no duty to determine whether any Special Interest is payable or the amount
thereof. 
 (E)    No Effect on Other Events of Default. No election pursuant to this
Section 7.03 with respect to a Reporting Event of Default will affect the rights of any Holder with respect to any other Event of Default, including with respect to any other Reporting Event of Default. 

Section 7.04. OTHER REMEDIES. 

(A)    Trustee May Pursue All Remedies. If an Event of Default occurs and is continuing, then the Trustee may pursue
any available remedy to collect the payment of any amounts due with respect to the Notes or to enforce the performance of any provision of this Indenture or the Notes.

 (B)    Procedural Matters. The Trustee may maintain a proceeding
even if it does not possess any of the Notes or does not produce any of them in such proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy following an Event of Default will not impair the right or remedy or
constitute a waiver of, or acquiescence in, such Event of Default. All remedies will be cumulative to the extent permitted by law. 
 
Section 7.05. WAIVER OF PAST DEFAULTS. 
 An Event of Default
pursuant to clause (i), (ii), (iv) or (vi) of Section 7.01(A) (that, in the case of clause (vi) only, results from a Default under any covenant that cannot be amended
without the consent of each affected Holder), and a Default that could lead to such an Event of Default, can be waived only with the consent of each affected Holder. Each other Default or Event of Default may be waived, on behalf of all Holders, by
the Holders of a majority in aggregate principal amount of the Notes then outstanding. If an Event of Default is so waived, then it will cease to exist. If a Default is so waived, then it will be deemed to be cured and any Event of Default arising
therefrom will be deemed not to occur. However, no such waiver will extend to any subsequent or other Default or Event of Default or impair any right arising therefrom. 

Section 7.06. CONTROL BY MAJORITY. 

Holders of a majority in aggregate principal amount of the Notes then outstanding may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law, this Indenture or the Notes, or that, subject to
Section 10.01, the Trustee determines may be unduly prejudicial to the rights of other Holders or may involve the Trustee in liability, unless the Trustee is offered security and indemnity satisfactory to the Trustee
against any loss, liability or expense to the Trustee that may result from the Trustee’s following such direction. 

Section 7.07. LIMITATION ON SUITS. 

No Holder may pursue any remedy with respect to this Indenture or the Notes (except to enforce (x) its rights to receive the principal of,
or the Redemption Price or Fundamental Change Repurchase Price for, or interest on, any Notes; or (y) the Company’s obligations to convert any Notes pursuant to Article 5), unless: 

(A)    such Holder has previously delivered to the Trustee notice that an Event of Default is continuing; 

(B)    Holders of at least twenty five percent (25%) in aggregate principal amount of the Notes then outstanding deliver a
request to the Trustee to pursue such remedy; 
 (C)    such Holder or Holders offer and, if requested, provide to the
Trustee security and indemnity satisfactory to the Trustee against any loss, liability or expense to the Trustee that may result from the Trustee’s following such request; 

(D)    the Trustee does not comply with such request within sixty (60) calendar days after its receipt of such
request and such offer of security or indemnity; and 

  
 - 61 - 










Table of Contents




 (E)    during such sixty (60) calendar day period, Holders of a
majority in aggregate principal amount of the Notes then outstanding do not deliver to the Trustee a direction that is inconsistent with such request. 

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another
Holder. The Trustee will have no duty to determine whether any Holder’s use of this Indenture complies with the preceding sentence. 
 
Section 7.08. ABSOLUTE RIGHT OF HOLDERS TO INSTITUTE SUIT FOR THE ENFORCEMENT
OF THE RIGHT TO RECEIVE PAYMENT AND CONVERSION CONSIDERATION. 

Notwithstanding anything to the contrary in this Indenture or the Notes (but without limiting Section 8.01), the
right of each Holder of a Note to bring suit for the enforcement of any payment or delivery, as applicable, of the principal of, or the Redemption Price or Fundamental Change Repurchase Price for, or any interest on, or the Conversion Consideration
due pursuant to Article 5 upon conversion of, such Note on or after the respective due dates therefor provided in this Indenture and the Notes, will not be impaired or affected without the consent of such Holder. 

Section 7.09. COLLECTION SUIT BY TRUSTEE. 

The Trustee will have the right, upon the occurrence and continuance of an Event of Default pursuant to clause (i), (ii)
or (iv) of Section 7.01(A), to recover judgment in its own name and as trustee of an express trust against the Company for the total unpaid or undelivered principal of, or Redemption Price or Fundamental Change
Repurchase Price for, or interest on, or Conversion Consideration due pursuant to Article 5 upon conversion of, the Notes, as applicable, and, to the extent lawful, any Default Interest on any Defaulted Amounts, and such further amounts
sufficient to cover the costs and expenses of collection, including compensation provided for in Section 
10.06. 
 Section 7.10. TRUSTEE MAY FILE PROOFS
OF CLAIM. 
 The Trustee has the right to (A) file such proofs of claim and other papers or documents
as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes) or its creditors or property and (B) collect, receive
and distribute any money or other property payable or deliverable on any such claims. Each Holder authorizes any custodian in such proceeding to make such payments to the Trustee, and, if the Trustee consents to the making of such payments directly
to the Holders, to pay to the Trustee any amount due to the Trustee for the reasonable compensation, expenses, disbursements and advances of the Trustee, and its agents and counsel, and any other amounts payable to the Trustee pursuant to
Section 10.06. To the extent that the payment of any such compensation, expenses, disbursements, advances and other amounts out of the estate in such proceeding, is denied for any reason, payment of the same will be secured
by a lien on, and will be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled

to receive in such proceeding (whether in liquidation or under any plan of reorganization or arrangement or otherwise). Nothing in this Indenture will be deemed to authorize the Trustee to
authorize, consent to, 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, or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding. 
 Section 7.11. PRIORITIES. 

The Trustee will pay or deliver in the following order any money or other property that it collects pursuant to this Article 7: 

First:    to the Trustee and its agents and attorneys for amounts due under
Section 10.06, including payment of all fees, compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

Second:    to Holders for unpaid amounts or other property due on the Notes, including the principal
of, or the Redemption Price or Fundamental Change Repurchase Price for, or any interest on, or any Conversion Consideration due upon conversion of, the Notes, ratably, and without preference or priority of any kind, according to such amounts or
other property due and payable on all of the Notes; and 
 Third:    to the Company or such other
Person as a court of competent jurisdiction directs. 
 The Trustee may fix a record date and payment date for any payment or delivery to
the Holders pursuant to this Section 7.11, in which case the Trustee will instruct the Company to, and the Company will, deliver, at least fifteen (15) calendar days before such record date, to each Holder and the
Trustee a notice stating such record date, such payment date and the amount of such payment or nature of such delivery, as applicable. 
 
Section 7.12. UNDERTAKING FOR COSTS. 
 In any suit for the enforcement of any
right or remedy under this Indenture or the Notes or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court, in its discretion, may (A) require the filing by any litigant party in such suit of an undertaking
to pay the costs of such suit, and (B) assess reasonable costs (including reasonable attorneys’ fees) against any litigant party in such suit, having due regard to the merits and good faith of the claims or defenses made by such litigant
party; provided, however, that this Section 7.12 does not apply to any suit by the Trustee, any suit by a Holder pursuant to Section 7.08 or any suit by one or more Holders of more
than ten percent (10%) in aggregate principal amount of the Notes then outstanding.

 Notwithstanding anything to the contrary in Section 8.02, the Company and the Trustee may amend or
supplement this Indenture or the Notes without the consent of any Holder to:

Company’s obligations under this Indenture or the Notes;

(I)    provide for or confirm the issuance of additional Notes pursuant to Section 2.03(B); 

(J)    comply with any requirement of the SEC in connection with any qualification of this Indenture or any supplemental
indenture under the Trust Indenture Act, as then in effect; or 
 (K)    make any other change to this Indenture or the
Notes that does not, individually or in the aggregate with all other such changes, adversely affect the rights of the Holders, as such, in any material respect (other than Holders that have consented to such change). 

Section 8.02. WITH THE CONSENT OF HOLDERS.

 (A)    Generally. Subject to Sections 8.01, 7.05 and 7.08 and the immediately
following sentence, the Company and the Trustee may, with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding (and, in the case of an amendment, supplement or waiver that affects Notes that are not
Affiliate Notes, a majority in aggregate principal amount of all Notes then outstanding that are not Affiliate Notes), amend or

Table of Contents




 
supplement this Indenture or the Notes or waive compliance with any provision of this Indenture or the Notes. Notwithstanding anything to the contrary in the foregoing sentence, but subject to
Section 8.01, without the consent of each affected Holder, no amendment or supplement to this Indenture or the Notes, or waiver of any provision of this Indenture or the Notes, may: 

(i)    reduce the principal, or extend the stated maturity, of any Note; 

(ii)    reduce the Redemption Price or Fundamental Change Repurchase Price for any Note or change the times
at which, or the circumstances under which, the Notes may or will be redeemed or repurchased by the Company; 

(iii)    reduce the rate, or extend the time for the payment, of interest on any Note; 

(iv)    make any change that adversely affects the conversion rights of any Note; 

(v)    impair the rights of any Holder set forth in Section 7.08 (as such section
is in effect on the Issue Date); 
 (vi)    change the ranking of the Notes; 

(vii)    make any Note payable in money, or at a place of payment, other than that stated in this Indenture
or the Note; 
 (viii)    reduce the amount of Notes whose Holders must consent to any amendment,
supplement, waiver or other modification; or 
 (ix)    make any direct or indirect change to any
amendment, supplement, waiver or modification provision of this Indenture or the Notes that requires the consent of each affected Holder. 

For the avoidance of doubt, pursuant to clauses (i), (ii), (iii) and (iv) of this
Section 8.02(A), no amendment or supplement to this Indenture or the Notes, or waiver of any provision of this Indenture or the Notes, may change the amount or type of consideration due on any Note (whether on an Interest
Payment Date, Redemption Date, Fundamental Change Repurchase Date or the Maturity Date or upon conversion, or otherwise), or the date(s) or time(s) such consideration is payable or deliverable, as applicable, without the consent of each affected
Holder. 
 (B)    Holders Need Not Approve the Particular Form of any Amendment. A consent of any Holder pursuant
to this Section 8.02 need approve only the substance, and not necessarily the particular form, of the proposed amendment, supplement or waiver. 

Section 8.03. NOTICE OF AMENDMENTS, SUPPLEMENTS
AND WAIVERS. 
 As soon as reasonably practicable after any amendment, supplement or waiver pursuant to
Section 8.01 or 8.02 becomes effective, the Company will send to the Holders and the Trustee notice that (A) describes the substance of such amendment, supplement or waiver in reasonable


  
 - 65 -

detail and (B) states the effective date thereof; provided, however, that the Company will not be required to provide such notice to the Holders if such amendment, supplement
or waiver is included in a periodic report filed by the Company with the SEC within four (4) Business Days of its effectiveness. The failure to send, or the existence of any defect in, such notice will not impair or affect the validity of such
amendment, supplement or waiver. 
 Section 8.04. REVOCATION, EFFECT AND
SOLICITATION OF CONSENTS; SPECIAL RECORD DATES; ETC. 

(A)    Revocation and Effect of Consents. The consent of a Holder of a Note to an amendment, supplement or waiver
will bind (and constitute the consent of) each subsequent Holder of any Note to the extent the same evidences any portion of the same indebtedness as the consenting Holder’s Note, subject to the right of any Holder of a Note to revoke (if not
prohibited pursuant to Section 8.04(B)) any such consent with respect to such Note by delivering notice of revocation to the Trustee before the time such amendment, supplement or waiver becomes effective. 

(B)    Special Record Dates. The Company may, but is not required to, fix a record date for the purpose of
determining the Holders entitled to consent or take any other action in connection with any amendment, supplement or waiver pursuant to this Article 8. If a record date is fixed, then, notwithstanding anything to the contrary in
Section 8.04(A), only Persons who are Holders as of such record date (or their duly designated proxies) will be entitled to give such consent, to revoke any consent previously given or to take any such action, regardless of
whether such Persons continue to be Holders after such record date; provided, however, that no such consent will be valid or effective for more than one hundred and twenty (120) calendar days after such record date. 

(C)    Solicitation of Consents. For the avoidance of doubt, each reference in this Indenture or the Notes to the
consent of a Holder will be deemed to include any such consent obtained in connection with a repurchase of, or tender or exchange offer for, any Notes. 

(D)    Effectiveness and Binding Effect. Each amendment, supplement or waiver pursuant to this Article 8
will become effective in accordance with its terms and, when it becomes effective with respect to any Note (or any portion thereof), will thereafter bind every Holder of such Note (or such portion). 

Section 8.05. NOTATIONS AND EXCHANGES. 

If any amendment, supplement or waiver changes the terms of a Note, then the Trustee or the Company may, in its discretion, require the Holder
of such Note to deliver such Note to the Trustee so that the Trustee may place an appropriate notation prepared by the Company on such Note and return such Note to such Holder. Alternatively, at its discretion, the Company may, in exchange for such
Note, issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, a new Note that reflects the changed terms. The failure to make any appropriate notation or issue a new Note
pursuant to this Section 8.05 will not impair or affect the validity of such amendment, supplement or waiver.

 Section 8.06. TRUSTEE TO
EXECUTE SUPPLEMENTAL INDENTURES. 
 The Trustee will execute and deliver any amendment or
supplemental indenture authorized pursuant to this Article 8; provided, however, that the Trustee need not (but may, in its sole and absolute discretion) execute or deliver any such amendment or supplemental indenture that
adversely affects the Trustee’s rights, duties, liabilities or immunities. In executing any amendment or supplemental indenture, the Trustee will be entitled to receive, and (subject to Sections 10.01 and 10.02) will be
fully protected in relying on, an Officer’s Certificate and an Opinion of Counsel stating that (A) the execution and delivery of such amendment or supplemental indenture is authorized or permitted by this Indenture; and (B) in the
case of the Opinion of Counsel, such amendment or supplemental indenture is valid, binding and enforceable against the Company in accordance with its terms. 

Article 9. SATISFACTION AND DISCHARGE; DEFEASANCE OF CERTAIN COVENANTS 

Section 9.01. TERMINATION OF COMPANY’S
OBLIGATIONS.

this Indenture, when: 
 (A)    all Notes then outstanding (other than Notes replaced pursuant to
Section 2.13) have (i) been delivered to the Trustee for cancellation; or (ii) become due and payable (whether on a Redemption Date, a Fundamental Change Repurchase Date, the Maturity Date, upon conversion or
otherwise) for an amount of cash or Conversion Consideration, as applicable, that has been fixed; 
 (B)    the Company
has caused there to be irrevocably deposited with the Trustee, or with the Paying Agent (or, with respect to Conversion Consideration, the Conversion Agent), in each case for the benefit of the Holders, or has otherwise caused there to be delivered

Section 2.13); 
 (C)    the Company has paid all other amounts payable by it under this
Indenture; and 
 (D)    the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of
Counsel, each stating that the conditions precedent to the discharge of this Indenture have been satisfied; 
 provided, however, that
Article 10 and Section 11.01 will survive such discharge and, until no Notes remain outstanding, Section 2.15 and the obligations of the Trustee, the Paying Agent and the Conversion Agent
with respect to money or other property deposited with them will survive such discharge.

acknowledge the satisfaction and discharge of this Indenture.

 Section 9.02. REPAYMENT TO
COMPANY. 
 Subject to applicable unclaimed property law, the Trustee, the Paying Agent and the Conversion Agent will, at
the Company’s written request, promptly deliver to the Company any cash, Conversion Consideration or other property held by any of them for payment or delivery on the Notes that remain unclaimed two (2) years after the date on which such
payment or delivery was due. After such delivery to the Company, the Trustee, the Paying Agent and the Conversion Agent will have no further liability to any Holder with respect to such cash, Conversion Consideration or other property, and Holders
entitled to the payment or delivery of such cash, Conversion Consideration or other property must look to the Company for payment as a general creditor of the Company. 

Section 9.03. REINSTATEMENT. 

If the Trustee, the Paying Agent or the Conversion Agent is unable to apply any cash or other property deposited with it pursuant to
Section 9.01 because of any legal proceeding or any order or judgment of any court or other governmental authority that enjoins, restrains or otherwise prohibits such application, then the discharge of this Indenture
pursuant to Section 9.01 will be rescinded; provided, however, that if the Company thereafter pays or delivers any cash or other property due on the Notes to the Holders thereof, then the Company will be
subrogated to the rights of such Holders to receive such cash or other property from the cash or other property, if any, held by the Trustee, the Paying Agent or the Conversion Agent, as applicable. 

Section 9.04. DEFEASANCE OF RESTRICTIVE COVENANTS. 

If: 

(A)    the Company has caused there to be irrevocably deposited, with the Trustee or the Paying Agent for the benefit of
the Holders, cash in an aggregate amount equal to the sum of (i) the remaining scheduled interest payments on each Note outstanding as of the time of such deposit (assuming, for these purposes, that Additional Interest and Special Interest
would accrue on such Note at their respective maximum rates per annum); and (ii) one hundred percent (100%) of the principal amount of each Note outstanding as of the time of such deposit (excluding, in the case of each of sub-clause (i) and (ii) above, any Notes referred to in Section 9.04(B) as to which the deposit referred to in Section 9.04(B) is made); 

(B)    with respect to each Note, if any, for which a Conversion Date has occurred, but the Conversion Consideration due
in respect of such Note has not been fully paid or delivered, as of the time of the deposit referred to in Section 9.04(A), the Company has caused there to be irrevocably deposited, with the Trustee or the Conversion Agent
for the benefit of the Holders, the maximum kind and amount of Conversion Consideration due in respect of such Note (together, if applicable, with (i) cash in the amount of any interest due on such Note pursuant to clause (i) of
Section 5.02(D); and (ii) an amount of cash equal to the Applicable Premium); 

(C)    the Company has instructed the Trustee, the Paying Agent or the Conversion Agent, as applicable, to pay or deliver
cash or other property due on the Notes from the cash or other property deposited pursuant to Section 9.04(A) and Section 9.04(B) as the same becomes due; 

  
 - 68 - 










Table of Contents




 (D)    as of the time of the deposits referred to in
Section 9.04(A) and Section 9.04(B), no default in the payment or delivery of any amount or property (including Conversion Consideration) on any Note has occurred and is continuing; 

(E)    the Company has delivered to the Trustee an Opinion of Counsel confirming that the Holders will not recognize any
income, gain or loss for federal income tax purposes as a result of the Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times, as would have been the case if such Covenant
Defeasance had not occurred; 
 (F)    such Covenant Defeasance will not result in a breach or violation of, or
constitute a default under, any material agreement or instrument (other than this Indenture, but solely in connection with the incurrence of any indebtedness to finance such Covenant Defeasance) to which the Company is a party or by which the
Company is bound; 
 (G)    the Company has delivered to the Trustee an Officer’s Certificate stating that the
deposits referred to in Section 9.04(A) and Section 9.04(B) were not made by the Company with the intent of preferring the Holders over the other creditors of the Company with the intent of
defeating, hindering, delaying or defrauding any creditors of the Company or others; and 
 (H)    the Company has
delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to such Covenant Defeasance have been complied with, 

then, notwithstanding anything to the contrary in this Indenture or the Notes, Section 3.09 will thereafter cease to be of any force
or effect, and, for the avoidance of doubt, any omission to thereafter comply with Section 3.09 will not in itself constitute a Default or Event of Default under the Notes. For the avoidance of doubt, the remainder of this
Indenture and the Notes will be unaffected by and Covenant Defeasance and will continue to be in full force and effect. 
 Each of the
Trustee, the Paying Agent and the Conversion Agent will return to the Company any cash or other property deposited with it pursuant to Section 9.04(A) and Section 9.04(B) that remains on deposit
after (x) all Notes have been paid in full and none remain outstanding; and (y) the Company has paid all other amounts payable by it under this Indenture.

matters as it may see fit and will incur no liability of any kind by reason of such inquiry or investigation.

Indenture Act), then it must eliminate such conflict within ninety (90) days or resign as Trustee. Each Note Agent will have the same rights and duties as the Trustee under this Section 10.03. 

Section 10.04. TRUSTEE’S DISCLAIMER. 

The Trustee will not be (A) responsible for, and makes no representation as to, the validity or adequacy of this Indenture or the Notes;
(B) accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture; (C) responsible for the use or application of any money
received by any Paying Agent other than the Trustee; and (D) responsible for any statement or recital in this Indenture, the Notes or any other document relating to the sale of the Notes or this Indenture, other than the Trustee’s
certificate of authentication. 
 Section 10.05. NOTICE OF DEFAULTS.

 If a Default or Event of Default occurs and is continuing and is known to the Trustee, then the Trustee will send Holders a notice of
such Default or Event of Default within ninety (90) days after it occurs or, if it is not known to the Trustee at such time, promptly (and in any event within ten (10) Business Days) after it becomes known to a Responsible Officer;
provided, however, that, except in the case of a Default or Event of Default in the payment of the principal of, or interest on, any Note, the Trustee may withhold such notice if and for so long as it in good faith determines that
withholding such notice is in the interests of the Holders. 
 Section 10.06. COMPENSATION
AND INDEMNITY. 
 (A)    The Company will, from time to time, pay the Trustee
reasonable compensation for its acceptance of this Indenture and services under this Indenture. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. In addition to the compensation for the
Trustee’s services, the Company will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it under this Indenture, including the reasonable compensation, disbursements and
expenses of the Trustee’s agents and counsel. 
 (B)    The Company will indemnify the Trustee against any and all
losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this
Section 10.06) and defending itself against any claim (whether asserted by the Company, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties under this
Indenture, except to the extent any such loss, liability or expense is proved to be attributable to its negligence, bad faith or willful misconduct. The Trustee will promptly notify the Company of any claim for which it may seek indemnity, but the
Trustee’s failure to so notify the Company will not relieve the Company of its obligations under this Section 10.06(B). The Company will defend such claim, and the Trustee will cooperate in such defense. If the Trustee
is advised by counsel that it may have defenses available to it that are in conflict with the defenses available to the Company, or

that there is an actual or potential conflict of interest, then the Trustee may retain separate counsel, and the Company will pay the reasonable fees and expenses of such counsel (including the
reasonable fees and expenses of counsel to the Trustee incurred in evaluating whether such a conflict exists). The Company need not pay for any settlement of any such claim made without its consent, which consent will not be unreasonably withheld.

 (C)    The obligations of the Company under this Section 10.06 will survive the resignation
or removal of the Trustee and the discharge of this Indenture. 
 (D)    To secure the Company’s payment
obligations in this Section 10.06, the Trustee will have a lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal of, or interest on, particular Notes,
which lien will survive the discharge of this Indenture. 
 (E)    If the Trustee incurs expenses or renders services
after an Event of Default pursuant to clause (ix) or (x) of Section 7.01(A) occurs, then such expenses and the compensation for such services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any Bankruptcy Law. 
 Section 10.07.
REPLACEMENT OF THE TRUSTEE. 
 (A)    Notwithstanding
anything to the contrary in this Section 10.07, a resignation or removal of the Trustee, and the appointment of a successor Trustee, will become effective only upon such successor Trustee’s acceptance of appointment as
provided in this Section 10.07. 
 (B)    The Trustee may resign at any time and be discharged
from the trust created by this Indenture by so notifying the Company. The Holders of a majority in aggregate principal amount of the Notes then outstanding may remove the Trustee by so notifying the Trustee and the Company in writing. The Company
may remove the Trustee if: 
 (i)    the Trustee fails to comply with
Section 10.09; 
 (ii)    the Trustee is adjudged to be bankrupt or insolvent
or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; 
 (iii)    a
custodian or public officer takes charge of the Trustee or its property; or 
 (iv)    the Trustee
becomes incapable of acting. 
 (C)    If the Trustee resigns or is removed, or if a vacancy exists in the office of the
Trustee for any reason, then (i) the Company will promptly appoint a successor Trustee; and (ii) at any time within one (1) year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the
Notes then outstanding may appoint a successor Trustee to replace such successor Trustee appointed by the Company. 

(D)    If a successor Trustee does not take office within sixty (60) days after the retiring Trustee resigns or is
removed, then the retiring Trustee, the Company or the Holders of at least ten percent (10%) in aggregate principal amount of the Notes then outstanding may petition any court of competent jurisdiction for the appointment of a successor Trustee.

 (E)    If the Trustee, after written request by a Holder of at least six
(6) months, fails to comply with Section 10.09, then such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

(F)    A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the
Company, upon which notice the resignation or removal of the retiring Trustee will become effective and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will send notice of
its succession to Holders. The retiring Trustee will, upon payment of all amounts due to it under this Indenture, promptly transfer all property held by it as Trustee to the successor Trustee, which property will, for the avoidance of doubt, be
subject to the lien provided for in Section 10.06(D). 
 Section 10.08.
SUCCESSOR TRUSTEE BY MERGER, ETC. 
 If the Trustee
consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another Person, then such Person will become the successor Trustee without any further act. 

Section 10.09. ELIGIBILITY; DISQUALIFICATION. 

There will at all times be a Trustee under this Indenture that is a corporation organized and doing business under the laws of the United
States of America or of any state thereof, that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least
$100.0 million as set forth in its most recent published annual report of condition.
