Debentures shall be substantially in the form set forth in Exhibit A. The terms and provisions contained in the Form of Debenture attached as Exhibit A hereto shall constitute, and are hereby expressly made, a part of this Indenture and,

Any of the Debentures may have such letters, numbers or other marks of identification and such notations, legends, endorsements or changes as
the Officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture, or as may be required by the Trustee, the Depositary, or as may be required

 Section 2.03
Maturity Date; Interest. The Debentures shall be issuable in registered form without coupons in denominations of $1,000 principal amount and whole multiples thereof. Each Debenture shall be dated the date of its authentication and shall bear

of the number of days actually elapsed in a 30-day month. 
 On the Maturity Date, each Holder shall be entitled to receive $1,000 in cash
for each $1,000 principal amount of Debentures held on such date, together with accrued and unpaid interest to, but excluding, the Maturity Date. With respect to Global Debentures, principal and interest shall be paid to the Depositary in

on any Regular Record Date with respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date. Notwithstanding the foregoing any Debentures or portion thereof surrendered for conversion during
the period from the close of business on the Regular Record Date for any Interest Payment Date to the close of business on the Business Day preceding the

applicable Interest Payment Date shall be accompanied by payment, in immediately available funds or other funds acceptable to the Company, of an amount equal to the interest that has accrued and

immediately preceding the Maturity Date, (2) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, or, if later, the Business Day on
which such interest is payable pursuant to Section 13.07, (3) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date or (4) to the extent of any overdue
interest, if any, that exists at the time of conversion with respect to such Debentures. For the avoidance of doubt, all record Holders at the close of business on the Regular Record Date immediately preceding the Maturity Date and any Fundamental
Change Repurchase Date will receive the full interest payment due on the Maturity Date or Fundamental Change Repurchase Date, regardless of whether their Debentures have been converted following such Regular Record Date and converting Holders shall
not be required to make an equivalent payment upon conversion. 
 The Company shall pay interest on (i) Global Debentures by wire
transfer in immediately available funds to the account of the Depositary or its nominee, (ii) Debentures in certificated form having a principal amount of less than $2,000,000, by check mailed to Holders of such Debentures, provided,
however, that on the Maturity Date, interest in respect of outstanding Debentures shall be payable at the office of the Company maintained by the Company for such purposes, which shall initially be the Corporate Trust Office of the Trustee and
(iii) Debentures in certificated form having a principal amount of $2,000,000 or more, by wire transfer in immediately available funds at the election of the Holders of such Debentures duly delivered to the Trustee at least five Business Days

Debenture is authenticated, the Debenture shall be valid so long as such individual was an Officer at the time of execution of the Debenture. 

A Debenture shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent. The signature shall be
conclusive evidence that the Debenture has been authenticated under this Indenture. 
 The Trustee shall at any time, and from time to time,

agents. Each Debenture shall be dated as of the date of its authentication. 
 Prior to the issuance of Debentures, the Trustee shall have
received and (subject to Section 7.02) shall be fully protected in conclusively relying on: (a) an Officer’s Certificate complying with Section 13.04 and (b) an Opinion of Counsel complying with Section 13.04.

determines that such action may not lawfully be taken; or (b) if the Trustee in good faith shall determine that such action would expose the Trustee to personal liability to Holders of any then outstanding Debentures.

 The Trustee may appoint an authenticating agent reasonably acceptable to the Company to
authenticate the Debentures. Any such appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Company. Unless limited by the terms of such appointment, an authenticating agent may
authenticate Debentures whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with the Company or an
Affiliate.

are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Debentures that the Holder making the exchange is entitled to receive bearing registration numbers not contemporaneously outstanding.

 All Debentures issued upon any registration of transfer or exchange of Debentures shall be the valid, legal and binding obligations of

Company or the Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company, and the Debentures shall be duly executed by the Holder thereof or his attorney duly authorized in
writing.

the Trustee may require payment by the Holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of such Debentures (other than any such
transfer tax or similar governmental charge payable upon exchanges pursuant to Section 2.09 or Section 6.05).

Commitment Debentures become so eligible), unless otherwise required by law, subject to Section 2.06(c), all such Debentures shall be represented by one or more Debentures in global form (each, a “Global Debenture”) registered in
the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Debenture that does not involve the issuance of a certificated Debenture shall be effected through the Depositary (but not the
Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor. The Depositary shall be a clearing agency registered under the Exchange Act.

 (b) Each Global Debenture authenticated under this Indenture shall be registered in the name of the Depositary or a nominee thereof
and delivered to such Depositary or a custodian, and each such Global Debenture shall constitute a single Debenture for purposes of this Indenture. 

(c) The Company initially appoints The Depository Trust Company to act as Depositary with respect to each Global Debenture. Initially, each
Global Debenture shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co. Notwithstanding any other provisions of this
Indenture or the Debentures (except as provided in Section 2.06 (d) below), no Global Debentures may be exchanged in whole or in part for Debentures registered, and no transfer of a Global Debenture in whole or in part may be registered, in the
name of any Person other than the Depositary or a nominee thereof unless (A) the Depositary (x) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Debenture or (y) has ceased to be a
clearing agency registered under the Exchange Act, and a successor depositary has not been appointed by the Company within 90 calendar days, or (B) the Company, at any time and in its sole discretion, notifies the Trustee in writing that it no
longer wishes to have all the Debentures represented by Global Debentures. Any Global Debentures exchanged pursuant to this Section 2.06(c) shall be so exchanged in whole and not in part. Neither the Trustee or any Agent shall bear any liability or
responsibility for the action or inaction of any Depositary. 
 (d) In addition, certificated Debentures shall be issued in exchange for
beneficial interests in a Global Debenture upon request by or on behalf of the Depositary in accordance with customary procedures following the request of a beneficial owner seeking to enforce its rights under the Debentures or this Indenture,
including its rights following the occurrence of an Event of Default. 
 (e) Debentures issued in exchange for a Global Debenture or any
portion thereof pursuant to clause (b) or (c) above shall be issued in definitive, global form, without interest coupons, shall have a principal amount equal to that of such Global Debenture or portion thereof to be so exchanged, and shall
be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear the legend of the Depository set forth in Exhibit A hereto. Any Global Debenture to be exchanged in whole shall be surrendered by
the Depositary to the Trustee or the Registrar. With regard to any Global Debenture to be exchanged in part, either such Global Debenture shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its
nominee with respect to such Global Debenture, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Registrar. Upon any such
surrender or adjustment, the Trustee shall authenticate and deliver the Debenture issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof. 

(f) Subject to the provisions of Section 2.06(h) below, the registered Holder may grant proxies and otherwise authorize any Person, including
Agent Members (as defined below) and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Debentures. 

(g) In the event of the occurrence of any of the events specified in Section 2.06(c) above or upon any request described in Section 2.06(d)
above, the Company will promptly make available to the Trustee a reasonable supply of certificated Debentures in definitive, fully registered form, without interest coupons. 

  
 13 








 (h) Neither any members of, or participants in, the Depositary (collectively, the “Agent
Members”) nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Debenture registered in the name of the Depositary or any nominee thereof, or under any such Global
Debenture, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any Agent of the Company or the Trustee as the absolute owner and Holder of such Global Debenture for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company or the Trustee, or any Agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such
nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a Holder
of any Debenture. 
 (i) At such time as all interests in a Global Debenture have been repurchased, converted, cancelled or exchanged for
Debentures in certificated form, such Global Debenture shall, upon receipt thereof, be cancelled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the custodian for the Global Debenture,
subject to Section 2.10. At any time prior to such cancellation, if any interest in a Global Debenture is repurchased, converted, canceled or exchanged for Debentures in certificated form, the principal amount of such Global Debenture shall, in
accordance with the standing procedures and instructions existing between the Depositary and the custodian for the Global Debenture, be appropriately reduced, and an endorsement shall be made on such Global Debenture, by the Trustee or the custodian
for the Global Debenture, at the direction of the Trustee, to reflect such reduction. 
 Section 2.07 Restrictions on Transfer.

 (a) Non-Commitment Debentures. 

(i) Every Non-Commitment Debenture (and all securities issued in exchange therefore on in substitution thereof) that bears or
is required under this Indenture to bear the legend set forth in Exhibit A (together with any Common Stock issued upon conversion of the Non-Commitment Debenture that is required to bear the legend set forth in Exhibit A, collectively the
“Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.07(a) (including those set forth in the legend (the “Restricted Security Legend”) in Exhibit A) until such
Restricted Security Legend is removed. As used in this Section 2.07(a) and Section 2.07(b) the term “transfer” means any sale, pledge, loan, transfer or other disposition whatsoever of any Restricted Security or any interest
therein. 
 (ii) Until the date that is the later of (1) the Free Trade Date or such other period of time as permitted
by Rule 144 and (2) such later date, in any, as may be required by applicable laws, any certificate evidencing such Non-Commitment Debenture (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if
any, issued upon conversion thereof, which shall bear the legend set forth in Section 2.07(b), if applicable) shall bear a legend in substantially the form of the Restricted Security Legend, unless such Non-Commitment Debenture has been sold or
otherwise transferred (A) to the Company or any of its Subsidiaries, (B) pursuant to a registration statement that has been declared or has become effective under the Security Act (and which continues to be effective at the time of such
transfer), (C) pursuant to the exemption from registration provided by Rule 144 (if available) or (D) pursuant to any other available exemption from the registration requirements of the Securities Act. 

(iii) In connection with any transfer of the Non-Commitment Debentures prior to the Resale Restriction Termination Date, the
Holder must complete and deliver the Form of Assignment and Transfer set forth on the certificate representing the Debenture, with the appropriate box checked, to the Trustee (or any successor Trustee, as applicable). 

(iv) Any certificated Non-Commitment Debenture (or any security issued in exchange or substitution therefor) that has been
transferred, replaced or exchanged on or after the Free Trade Date or that has been transferred pursuant to a registration statement that has been declared effective under the Securities Act may be exchanged for a new certificated


  
 14 








 
Non-Commitment Debenture or Non-Commitment Debentures of like tenor and aggregate principal amount that do not bear the Restricted Security Legend required by Section 2.07(a)(i) hereof. To
exercise such right of exchange, the Holder of such Non-Commitment Debenture must surrender such Non-Commitment Debenture in accordance with the provisions of Section 2.06(e) hereof and deliver any additional documentation reasonably required by the
Company, the Trustee or the Registrar in connection with such exchange. 
 (v) If, on the Free Trade Date, or the next
succeeding Business Day if the Free Trade Date is not a Business Day, any Non-Commitment Debentures are represented by a Global Debenture that is subject to the restrictions set out in Section 2.07(a)(i) (any such Global Debenture, a
“Restricted Global Debenture”), as promptly as practicable, the Company will automatically exchange every beneficial interest in each Restricted Global Debenture for beneficial interests in Global Debentures that are not subject to
the restrictions set forth in the Restricted Security Legend and in Section 2.07(a)(i) hereof (an “Unrestricted Global Debenture”), in accordance with the Applicable Procedures. 

(vi) To effect such automatic exchange (the “Automatic Exchange”), the Company will (1) deliver to the
Depositary an instruction letter for the Depositary’s mandatory exchange process at least 15 days immediately prior to the Free Trade Date and (2) deliver to each of the Trustee and the Registrar (A) a duly completed free
transferability certificate in the form set forth on Exhibit B (the “Free Transferability Certificate”) at least 5 days prior to the Free Trade Date, (B) an authentication order at least 5 days prior to the Free Trade Date,
(C) an Officer’s Certificate at least 5 days prior to the Free Trade Date and (D) an Opinion of Counsel with respect to the Automatic Exchange subject to any changes in the Applicable Procedures. The first date on which the Trustee
authenticates the Freely Tradable Debentures and the Depository initiates the mandatory exchange shall be known as the “Resale Restriction Termination Date.” 

(vii) Notwithstanding anything to the contrary in this Section 2.07, the Company will not be required to deliver the Free
Transferability Certificate if it reasonably believes that removal of the Restricted Securities Legend or the changes to the CUSIPs for the Debentures could result in or facilitate transfers of the Debentures in violation of applicable law. 

(viii) Any Additional Debentures that are Restricted Securities, which are issued with different restricted CUSIP numbers than
the Non-Commitment Debentures and issued on a date other than the date of this Indenture, shall be treated separately, but be subject to the provisions of this Section 2.07(a), except that the Free Trade Date in respect of such Additional Debentures
shall be the 365th calendar day following the Issue Date of such Additional Debentures. 

(b) Common Stock. 

(i) Until the Resale Restriction Termination Date, with respect to the related Debentures being converted, any stock
certificate representing Common Stock issue upon conversion of such Non-Commitment Debenture shall bear a Restricted Security Legend, with appropriate modifications, unless the Non-Commitment Debenture or such Common Stock has been sold or otherwise
transferred (A) to the Company or any of its Subsidiaries, (B) pursuant to a registration statement that has been declared or has become effective under the Security Act (and which continues to be effective at the time of such transfer),
(C) pursuant to the exemption from registration provided by Rule 144 (if available) or (D) pursuant to any other available exemption from the registration requirements of the Securities Act. 

(ii) Any such Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms may,
upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of
shares of Common Stock, which shall not bear the restrictive legend required by this Section 2.07(b). 

  
 15 








 (c) Every Commitment Debenture (and all securities issued in exchange therefor or in substitution
thereof) and any shares of Common Stock issuable upon conversion of such Debenture (with appropriate modifications) shall bear the legend set forth in Exhibit A, and be subject to the restrictions on transfer as set forth therein, during
(i) the period of one year from the date of issuance of such Debentures and (ii) regardless of the date of issuance, so long as any purchaser, transferee or assignee of such Debentures or shares of Common Stock (a
“Transferee”) would receive “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act; provided that such legend shall be removed after any such Transferee that is not an Affiliate of the
Company has held the Debentures or shares of Common Stock issuable upon conversion thereof for one year. Any Commitment Debentures or shares of Common Stock required to bear the legend as set forth in this clause (c) (the “Restricted
Commitment Debenture Legend”) shall be in registered definitive form and any Transferee thereof shall agree to be bound by such restrictions on transfer. 

(d) The Company shall not, and shall use its reasonable efforts to cause its Affiliates (or any Person who was an Affiliate of the Company at
any time during the preceding three months) not to, resell any Non-Commitment Debentures or Common Stock issued upon the conversion or exchange of such Debentures that are repurchased or owned by the Company or such Affiliate (or such Person, as the
case may be), as the case may be, unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Debenture or Common Stock, as the case may
be, no longer being a “restricted security” (within the meaning of Rule 144(a)(3) under the Securities Act). The Company shall cause any Debenture that is repurchased or owned by it to be surrendered to the Trustee for cancellation in
accordance with Section 2.10. 
 Section 2.08 Mutilated, Destroyed, Lost and Stolen Debentures. 

If a mutilated Debenture is surrendered to the Registrar or if the Holder claims that the Debenture has been lost, destroyed or wrongfully
taken, the Company shall issue and the Trustee shall authenticate a replacement Debenture if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Holder (i) satisfies the Company or the Trustee within a
reasonable time after he has notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (ii) makes such request to the Company or the Trustee prior to the Debenture
being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “Protected Purchaser”) and (iii) satisfies any other reasonable requirements of the Trustee. If required by the Trustee
or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Trustee to protect the Company, the Trustee, the Paying Agent and the Registrar from any loss that any of them may suffer if a Debenture is replaced. The
Company and the Trustee may charge the Holder for their expenses in replacing a Debenture. In case any Debenture which has matured or is about to mature, has been called for redemption, has been surrendered for repurchase or is about to be converted
in accordance with Article 8, shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Debenture, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender
thereof except in the case of a mutilated Debenture), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may
be required by them to save each of them harmless for any loss, liability, cost or expense caused by or in connection with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, the
Trustee and, if applicable, any Paying Agent evidence to their satisfaction of the destruction, loss or theft of such Debentures and of the ownership thereof. 

Every replacement Debenture issued pursuant to this Section 2.08 is an additional obligation of the Company. 

The provisions of this Section 2.08 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the
replacement or payment or conversion of mutilated, destroyed, lost or stolen Debentures. 
 Section 2.09 Temporary Debentures.
Pending the preparation of Debentures in certificated form, the Company may execute, and the Trustee or an authenticating agent appointed by the Trustee shall, upon the Company Order, authenticate and deliver temporary Debentures (printed,
lithographed, typewritten, photocopied or otherwise produced). Temporary Debentures shall be issuable in any authorized denomination, and substantially in the form of the Debentures in certificated form, but with such omissions, insertions and
variations as may be 

  
 16 








 
appropriate for temporary Debentures, all as may be determined by the Company. Every such temporary Debenture shall be executed by the Company and authenticated by the Trustee or such
authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Debentures in certificated form. Without unreasonable delay, the Company will execute and deliver to the Trustee or such
authenticating agent Debentures in certificated form and thereupon any or all temporary Debentures may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 2.14 and the Trustee or such
authenticating agent shall authenticate and make available for delivery in exchange for such temporary Debentures an equal aggregate principal amount of Debentures in certificated form. Such exchange shall be made by the Company at its own expense
and without any charge therefor. Until so exchanged, the temporary Debentures shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Debentures in certificated form authenticated and
delivered hereunder. 
 Section 2.10 Cancellation. The Company at any time may surrender Debentures to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Debentures surrendered to them for registration of transfer, exchange, payment or conversion. The Trustee and no one else shall cancel all Debentures surrendered for
registration of transfer, exchange, payment, replacement, cancellation or conversion and dispose of such canceled Debentures in accordance with its customary procedure. The Company may not issue new Debentures to replace Debentures that it has paid
or delivered to the Trustee for cancellation. The Trustee shall not authenticate Debentures in place of canceled Debentures other than pursuant to the terms of this Indenture. 

Section 2.11 CUSIP and ISIN Numbers. The Company in issuing the Debentures may use “CUSIP” and “ISIN” numbers
(if then generally in use), and, if so, the Trustee shall use “CUSIP” and “ISIN” numbers in all notices issued to Holders as a convenience to Holders; provided that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Debentures or as contained in any notice and that reliance may be placed only on the other elements of identification printed on the Debentures. The Company shall promptly notify the
Trustee in writing of any changes to the CUSIP and ISIN numbers. 
 Section 2.12 Additional Debentures. The Company may, from
time to time, subject to compliance with any other applicable provisions of this Indenture, without the consent of the Holders, create and issue pursuant to this Indenture additional Debentures (“Additional Debentures”), which shall
be treated as a single class with the Debentures issued on the Closing Date for all purposes under this Indenture and which shall have terms and conditions set forth in Exhibit A identical to those of the other outstanding Debentures, except that
Additional Debentures: 
  

	 	(i)	may have a different issue price than other outstanding Debentures; 

  

	 	(ii)	may have a different Issue Date from other outstanding Debentures; and 

  

	 	(iii)	may have a different amount of interest payable on the first Interest Payment Date after issuance than is payable on other outstanding Debentures; 


provided, that if such Additional Debentures are, as determined pursuant to an Opinion of Counsel, not fungible with the Non-Commitment Debentures
issued on the Issue Date for U.S. federal income tax purposes or for U.S. securities law purposes, as the case may be, such Additional Debentures will have one or more separate CUSIP numbers. No Additional Debentures may be issued if any Event of
Default has occurred and is continuing. 
 Section 2.13 Defaulted Amounts. Any Defaulted Amounts shall forthwith cease to
be payable to the Holder on the relevant payment date but shall accrue interest per annum at the then applicable interest rate on the outstanding Debentures from the required payment date (to the extent lawful). The Company may pay Defaulted Amounts
together with such interest thereon to the Persons who are Holders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee and shall
promptly deliver or cause to be delivered to each Holder a notice that states the special record date, the payment date and the amount of Defaulted Amounts to be paid. 

  
 17 








 Section 2.14 Registrar, Paying Agent, Conversion Agent and Trustee. 

(a) The Company shall maintain in the United States, an office or agency where Debentures may be presented or surrendered for payment (the
“Paying Agent”). The Company shall also maintain in the United States a Registrar in accordance with Section 3.02. The Registrar shall keep a register with respect to the Debentures (the “Register”) and to their
transfer and exchange. The Company will give prompt written notice to the Trustee of the name and address, and any change in the name or address, of each Registrar or Paying Agent. If at any time the Company shall fail to maintain any such required
Registrar, Paying Agent or shall fail to furnish the Trustee with the name and address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints
the Trustee as its agent to receive all such presentations, surrenders, notices and demands. 
 The Company may also from time to time
designate one or more co-registrars, additional paying agents or service agents and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its
obligations to maintain a Registrar and Paying Agent in the United States. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the name or address of any such co-registrar, additional
paying agent or service agent. The term “Registrar” includes any co-registrar; and the term “Paying Agent” includes any additional paying agent. 

The Company hereby appoints the Trustee as the initial Registrar and Paying Agent for the Debentures. The Company or any of its domestically
organized Subsidiaries may act as Paying Agent or Registrar. 
 The rights, privileges, protections, immunities and benefits given to the
Trustee under this Indenture including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each Agent acting hereunder. 

The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent or service agent not a party to this Indenture.
The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. 

The Company may remove any Registrar, Paying Agent or service agent for the Debentures upon written notice to such Registrar, Paying Agent or
service agent and to the Trustee; provided, however, that no such removal shall become effective until (i) acceptance of an appointment by a successor as evidenced by an appropriate agreement entered into by the Company and such
successor Registrar, Paying Agent or service agent, as the case may be, and delivered to the Trustee or (ii) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in
accordance with clause (i) above. The Registrar, Paying Agent or service agent may resign at any time upon written notice; provided, however, that the Trustee may resign as Paying Agent, Registrar or service agent only if the Trustee
also resigns as Trustee in accordance with Section 7.07. 
 (b) In addition, the Company shall maintain an office or agency where Debentures
may be presented for conversion (the “Conversion Agent”). The Company hereby initially designates the Trustee as the Conversion Agent. The Company further designates the Corporate Trust Office of the Trustee as its office where
Debentures may be surrendered for conversion. 
 The Company may at any time and from time to time vary or terminate the appointment of any
such office or appoint any additional offices for any or all purposes; provided, however, that until all of the Debentures have been delivered to the Trustee for cancellation, or moneys sufficient to pay the principal of and premium,
if any, and interest on the Debentures have been made available for payment and either paid or returned to the Company pursuant to the provisions of Section 11.03 hereof, the Company shall maintain an office or agency where Debentures may be
surrendered for conversion. The Company shall give prompt written notice to the Trustee, and notice to the Holders, of the appointment or termination of any such agents and of the location and any change in the location of any such office or agency.

 The Company may also from time to time designate one or more Conversion Agents and, from time to time, rescind such designations. The
Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the name or address of such Conversion Agent. 

  
 18 








 The rights, privileges, protections, immunities and benefits given to the Trustee under this
Indenture including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each Conversion Agent or other Agent acting hereunder. 

Section 2.15 Paying Agent to Hold Money in Trust. 

Prior to each due date of the principal and interest on the Debentures, the Company shall deposit with the Paying Agent (or if the Company or
a Subsidiary is acting as Paying Agent, segregate and hold in trust for the benefit of the Persons entitled thereto) a sum sufficient to pay such principal and interest when so becoming due. The Company shall require each Paying Agent (other than
the Trustee) to agree in writing that the Paying Agent will hold in trust, for the benefit of Holders, or the Trustee, all money held by the Paying Agent for the payment of principal of or interest on the Debentures, and shall notify the Trustee of
any Default by the Company in making any such payment. While any such Default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by
it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it shall segregate and hold in a
separate trust fund for the benefit of Holders all money held by it as Paying Agent. 
 Section 2.16 Holder Lists. 

The Registrar shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses
of Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company shall furnish, or cause the Registrar to furnish, to the Trustee at least five Business Day before each Interest Payment Date and at such
other times as the Trustee may request in writing a list, in such form and as of such date as the Trustee may reasonably require, of the names and addresses of Holders. 

Section 2.17 Outstanding Debentures. 

The Debentures outstanding at any time are all the Debentures authenticated by the Trustee except for those canceled by it, those delivered to
it for cancellation, those reductions in the interest on a Global Debenture effected by the Trustee in accordance with the provisions hereof and those described in this Section 2.17 as not outstanding. Subject to Section 2.18, a Debenture does not
cease to be outstanding because the Company or an Affiliate holds the Debenture. 
 If a Debenture is replaced pursuant to Section 2.08, it
ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Debenture is held by a Protected Purchaser. 

If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds on the Maturity Date money sufficient to pay
the Debentures (or portions thereof) payable on that date, and the Paying Agent is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture, then on and after that date the Debentures (or portions
thereof) cease to be outstanding and interest on them ceases to accrue. 
 Section 2.18 Treasury Holder Lists. 

In determining whether the Holders of the required principal amount of Debentures have concurred in any direction, waiver or consent,
Debentures owned by the Company or an Affiliate shall be disregarded (from both the numerator and the denominator) and deemed not to be outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any
such amendment, modification, direction, waiver or consent, only the Debentures that a Trust Officer actually knows are so owned shall be so disregarded. 

Section 2.19 Repurchase of Debentures in the Open Market or Otherwise. The Company may, to the extent permitted by law, and
directly or indirectly (regardless of whether such notes are surrendered to it), repurchase Debentures in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through
counterparties to private agreements, including by cash-settled swaps or other derivatives. 

  
 19 








 Section 2.20 Cancellation of Debentures Repurchased. The Company shall cause any
Debenture repurchased pursuant to Article 9 and Section 2.19 hereof to be surrendered to the Trustee for cancellation. Any Debentures so surrendered to the Trustee for cancellation will no longer be considered “outstanding” under this
Indenture and may not be reissued, resold or converted by the Company and will be cancelled promptly in accordance with Section 2.10. 

Article 3 
 Covenants
 
 Section 3.01 Payment of Debentures. The Company shall promptly pay the principal of and interest on the Debentures
on the dates and in the manner provided in the Debentures and in this Indenture. Principal and interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent holds in accordance with this Indenture money sufficient
to pay all principal and interest then due and the Trustee or the Paying Agent, as the case may be, is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture. 

The Company shall pay interest on overdue principal at the rate specified therefor in the Debentures, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful. 
 Section 3.02 Maintenance of Office or Agency. The Company
shall maintain an office or agency, where the Debentures may be surrendered for registration of transfer or exchange or for presentation for payment or for conversion, redemption or repurchase (the “Registrar”). As of the date of
this Indenture, such office is located at the office of the Trustee located at Wells Fargo Bank, N.A., 608 2nd Avenue South, 12th Floor,
Minneapolis, MN 55402, Attention: Bondholder Communications and, at any other time, at such other address as the Trustee may designate from time to time by notice to the Company. The Company shall give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency not designated or appointed by the Trustee. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations and surrenders may be made at the Corporate Trust Office. 
 The Company may also from time to time designate
co-registrars and one or more offices or agencies where the Debentures may be presented or surrendered for any or all such purposes and may from time to time rescind such designations. The Company will give prompt written notice to the Trustee of
any such designation or rescission and of any change in the location of any such other office or agency. 
 Section 3.03 Notice of
Occurrence of Default; Compliance Certificate. 
 (a) If a Default or Event of Default occurs with respect to the Debentures and if it
is known to the Company, the Company shall deliver to the Trustee promptly upon becoming aware of such Default or Event of Default written notice of such Default or Event of Default. Upon such written notice, the Trustee shall deliver within 90
calendar days after such Default or Event of Default is actually known to a Trust Officer written notice to the Holders of all uncured Defaults known to the Trust Officer. Except in the case of a Default or Event of Default in payment of principal
or interest on the Debentures or a Default or Event of Default in the delivery of shares of Common Stock due upon conversion of the Debentures, the Trustee may withhold notice if, in good faith, determines that withholding such notice is in the
interests of the Holders. 
 (b) The Company shall deliver to the Trustee within 120 calendar days after the end of each fiscal year of the
Company an Officer’s Certificate stating that a review of the Company’s activities during the preceding fiscal year has been made under the supervision of the signing Officer with a view to determining whether the Company has kept,
observed, performed and fulfilled its obligations under this Indenture and further stating, as to the Officer signing such certificate, whether to the best of such Officer’s knowledge the Company during such preceding fiscal year has kept,
observed, performed and fulfilled each and every such covenant contained in this Indenture, and that in the course of the performance by the signer of its duties as Officer of the Company it would 

  
 20 








 
normally have knowledge of any Default and whether or not the signer knows of any Default that occurred during such period. If the Officer does know of any Default, the certificate shall describe
the Default, its status and what action the Company is taking or proposes to take with respect thereto. 
 Section 3.04 Payment of
Taxes and Other Claims. The Company shall pay or discharge, or cause to be paid or discharged, before the same may become delinquent, (i) all taxes, assessments and governmental charges levied or imposed upon the Company or any Significant
Subsidiary or upon the income, profits or property of the Company or any Significant Subsidiary, (ii) all claims for labor, materials and supplies which, if unpaid, might by law become a lien or charge upon the property of the Company or any
Significant Subsidiary and (iii) all stamp taxes and other duties, if any, which may be imposed by the United States or any political subdivision thereof or therein in connection with the issuance, transfer, exchange, conversion, redemption or
repurchase of any Debentures or with respect to this Indenture; provided, that, in the case of clauses (i) and (ii), the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge
or claim (A) if the failure to do so will not, in the aggregate, have a material adverse impact on the Company, or (B) if the amount, applicability or validity is being contested in good faith by appropriate proceedings. 

Section 3.05 Further Instruments and Acts. The Company shall execute and deliver such further instruments and do such further acts
as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture. 
 Section 3.06 SEC
Reports. The Company shall, so long as any of the Debentures are outstanding, file any document or report, which the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, with the Trustee within 15
days after such documents or reports are required to be filed with the SEC (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act and, for the avoidance of doubt, excluding any portions of such reports subject to
confidential treatment in accordance with SEC rules). Documents filed by the Company with the SEC via the EDGAR system (or any successor thereto) shall be deemed to be filed with the Trustee as of the time such documents are filed via EDGAR. The
exclusive remedies for any failure by the Company to file such documents or reports with the Trustee pursuant to this Section 3.06 are set forth in Section 5.07 hereof. Delivery of such reports and documents to the Trustee is for informational
purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants
hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates) and the Trustee shall have no responsibility or liability for the filing, timeliness or accuracy of such reports, information or documents. 

Section 3.07 Rule 144A Information Requirement. At any time the Company is not subject to Section 13 or 15(d) of the Exchange
Act, the Company shall, so long as any of the Debentures or any shares of Common Stock issuable upon conversion of thereof, will at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities
Act, promptly provide to the Trustee and shall, upon written request, provide to any Holder, beneficial owner or prospective purchaser of such Debentures or shares of Common Stock issuable upon conversion of such Debentures the information required
to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Debentures or shares of Common Stock pursuant to Rule 144A. The Company shall take such further action as any Holder or beneficial owner of such
Debentures or shares of Common Stock may reasonably request to the extent from time to time required to enable such Holder or beneficial owner to sell such Debentures or shares of Common Stock in accordance with Rule 144A. 

Section 3.08 Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at
any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this
Indenture or the Debentures; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of
any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted. 

Section 3.09 Corporate Existence. Subject to Article 4, the Company will do or cause to be done all things necessary to preserve
and keep in full force and effect its corporate existence and the corporate, partnership or other existence of each Significant Subsidiary in accordance with the respective organizational documents of each

Significant Subsidiary and the rights (charter and statutory), licenses and franchises of the Company and its Significant Subsidiaries; provided, however, that the Company shall not be
required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any Significant Subsidiary, if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct
of the business of the Company and its Subsidiaries taken as a whole and that the loss thereof is not adverse in any material respect to the Holders. 

Section 3.10 Money For Debentures Payments to be Held in Trust. If the Company shall at any time act as its own Paying Agent with
respect to the Debentures, it shall, on or before each due date of the principal of and premium, if any, and interest, if any, on any of the Debentures, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to
pay the principal and premium or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided. The Company shall promptly notify the Trustee of any failure by the Company (or any other obligor of
the Debentures) to make any payment of principal of or premium, if any, or interest, if any, on the Debentures. 
 Whenever the Company
shall have one or more Paying Agents for the Debentures, it shall, on or before each due date of the principal of and premium, if any, and interest, if any, on the Debentures, deposit with such Paying Agents sums sufficient (without duplication) to
pay the principal and premium or interest so becoming due, such sums to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company shall promptly notify
the Trustee of any failure by it so to act. 
 The Company shall cause each Paying Agent for the Debentures, other than the Company or the
Trustee, to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section 3.10, that such Paying Agent shall: 

(a) hold all sums held by it for the payment of the principal of and premium, if any, or interest, if any, on the Debentures in trust for the
benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; 
 (b)
give the Trustee notice of any failure by the Company (or any other obligor upon the Debentures) to make any payment of principal of or premium, if any, or interest, if any, on the Debentures; and 

(c) at any time during the continuance of any such failure, upon the written request of the Trustee, forthwith pay to the Trustee all sums so
held in trust by such Paying Agent and furnish to the Trustee such information as it possesses regarding the names and addresses of the Persons entitled to such sums. 

The Company may at any time pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or
such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent and, if so stated in a Company Order delivered to the Trustee, in accordance with the provisions
of Article 11; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. 

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of and
premium, if any, or interest, if any, on any Debenture and remaining unclaimed for two years after such principal and premium, if any, or interest, if any, has become due and payable shall be paid to the Company on request of the Company, or, if
then held by the Company, shall be discharged from such trust; and, upon such payment or discharge, the Holder of such Debenture shall, as an unsecured general creditor and not as the Holder of an outstanding Debenture, look only to the Company for
payment of the amount so due and payable and remaining unpaid, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make any such payment to the Company, may at the expense of the Company cause to be delivered, on one occasion only, notice to such Holder that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days from the date of such mailing, any unclaimed balance of such money then remaining will be paid to the Company.

 Article 4 

Successors 

Section 4.01 When Company May Merge, Etc. The Company shall not, in a single transaction or a series of related transactions,
consolidate with or merge with or into any other Person or sell, convey, transfer or lease its property and assets substantially as an entirety to another Person unless: 

(a) either (i) the Company is the continuing corporation, or (ii) the directly resulting, surviving or transferee Person (if other
than the Company) is a corporation or limited liability company organized and existing under the laws of the United States, any state thereof or the District of Columbia and such Person assumes, by a supplemental indenture and a supplemental
agreement, all of the Company’s obligations under the Debentures and this Indenture; 
 (b) immediately after giving effect to the
transaction described above, no Default or Event of Default has occurred and is continuing; 
 (c) if as a result of such transaction,
common stock or other securities issued by a third party would be Reference Property, such third party fully and unconditionally assumes or guarantees all obligations of the Company or such surviving Person under the Debentures and this Indenture;
and 
 (d) the Company has, at or prior to the effective date of such consolidation, merger or transfer, delivered to the Trustee the
Officer’s Certificate and Opinion of Counsel pursuant to Section 4.03, if applicable, each stating that such consolidation, merger or transfer is permitted by the Indenture and such other matters as may be required by Section 13.05. 

Section 4.02 Successor Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or lease in which the
Company is not the continuing corporation and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and reasonably satisfactory in form and substance to the Trustee, of the due and punctual
payment of the principal of, and premium, if any, and interest on all of the Debentures, and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed or satisfied by the Company, such
successor Person shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of this first part, and SunPower Corporation shall be discharged from its obligations under the Debentures and
this Indenture. Such successor Person thereupon may cause to be signed, and may issue either in its own name or in the name of SunPower Corporation any or all of the Debentures, issuable hereunder that theretofore shall not have been signed by the
Company and delivered to the Trustee; and, upon the order of such successor Person instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or
cause to be authenticated and delivered, any Debentures that previously shall have been signed and delivered by the officers of the Company to the Trustee for authentication, and any Debentures that such successor Person thereafter shall cause to be
signed and delivered to the Trustee for that purpose. All the Debentures so issued shall in all respects have the same legal rank and benefit under this Indenture as the Debentures theretofore or thereafter issued in accordance with the terms of
this Indenture as though all of such Debentures had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance, transfer or lease, upon compliance with this Article 4 the Person named as the
“Company” in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 4 may be dissolved, wound up and liquidated at any time thereafter and such Person shall be
discharged from its liabilities as obligor and maker of the Debentures and from its obligations under this Indenture. 

  
 23 








 Section 4.03 Opinion of Counsel to be Given Trustee. Prior to execution of any
supplemental indenture pursuant to this Article 4, the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such
assumption complies with the provisions of this Article 4. 
 Article 5 

Default and Remedies  

Section 5.01 Events of Default. 

An “Event of Default” occurs when any of the following occurs (whatever the reason for such Event of Default and whether it
shall be occasioned by the provisions of this Article 5 or be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or
governmental body): 
 (a) the Company fails to pay any interest on the Debentures when due and such failure continues for a period of 30
calendar days; or 
 (b) the Company fails to pay the principal of the Debentures when due at maturity, the Company shall fail to pay the
Redemption Price, or the Company shall fail to pay the Fundamental Change Repurchase Price in respect of any Debentures when due; or

(d) the Company fails to provide the notice required in Section 9.01(b) of an anticipated effective date or actual effective date of a
Fundamental Change for a period of five Business Days after such notice was required to be delivered; or 
 (e) the Company fails to perform
or observe any other term, covenant or agreement contained in the Debentures or this Indenture and the failure continues for a period of 60 calendar days after written notice of such failure is given to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 25% in aggregate principal amount of the then-outstanding Debentures; provided, however, this Section 5.01(e) shall not apply to any failure by the Company to satisfy its obligations set forth in
Section 3.06, for which the payments described under that Section 5.07 shall be considered full compliance with its obligations thereunder; or 

(f) the Company fails to pay when due (whether at stated maturity or otherwise), or a default that results in the acceleration of maturity of,
any Debt for borrowed money in excess of $50,000,000 of the Company or any Significant Subsidiary of the Company, unless such Debt is discharged, or such acceleration is rescinded, stayed or annulled, within a period of 30 calendar days after
written notice of such failure or default to the Company by the Trustee or to the Company and the Trustee by Holders of at least 25% in aggregate principal amount of the then-outstanding Debentures; or 

(g) the Company, or any Significant Subsidiary, pursuant to or within the meaning of Bankruptcy Law: 

(i) commences a voluntary case; 

(ii) consents to the entry of an order for relief against it in an involuntary case; 

(iii) consents to the appointment of a Custodian of it or for any substantial part of its property; 

(iv) makes a general assignment for the benefit of its creditors; or 

  
 24

 (h) a court of competent jurisdiction enters an order or decree under Bankruptcy Law that: 

(i) is for relief against the Company or any Significant Subsidiary in an involuntary case; 

(ii) appoints a Custodian of the Company or any Significant Subsidiary or for any substantial part of its property; 

(iii) orders the winding up or liquidation of the Company or any Significant Subsidiary; or 

(iv) any similar relief is granted under any foreign laws and, in each case, the order or decree remains unstayed and in effect
for 60 days. 
 Section 5.02 Acceleration of Maturity; Rescission and Annulment. 

If an Event of Default with respect to outstanding Debentures (other than an Event of Default specified in Section 5.01(g) or 5.01(h) hereof
with respect to the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then-outstanding Debentures, by written notice to the Company and the Trustee, may declare due and payable 100% of
the principal amount of all outstanding Debentures plus any accrued and unpaid interest to the date of payment. Upon a declaration of acceleration, such principal and accrued and unpaid interest to the date of payment shall be immediately due and
payable. 
 If an Event of Default specified in Section 5.01(g) or 5.01(h) hereof occurs and continues with respect to the Company, all
unpaid principal of and accrued and unpaid interest on the outstanding Debentures shall automatically become and be immediately due and payable, without any declaration or other act on the part of the Trustee or any Holder. 

The Holders of a majority in aggregate principal amount of the outstanding Debentures, by written notice to the Company and the Trustee, may
rescind and annul an acceleration and its consequences if prior to the Trustee obtaining a judgment or decree for payment of the money due: 

(i) the Company has paid (or deposited with the Trustee a sum sufficient to pay) (A) all overdue interest on all
Debentures; (B) the principal amount of any Debentures that has become due otherwise than by such declaration of acceleration; (C) to the extent that payment of such interest is lawful, interest upon overdue interest; and (D) all sums
paid or advanced by the Trustee under this Indenture and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and 

(ii) all Events of Default, other than the non-payment of principal or accrued and unpaid interest on the Debentures which has
become due solely because of the acceleration, have been cured or waived, 
 provided, however, that in the event such declaration of acceleration
has been made based on the existence of an Event of Default under Section 5.01(f) hereof and such Event of Default has been remedied, cured or waived in accordance with Section 5.01(f) hereof, then, without any further action by the Holders, such
declaration of acceleration shall be rescinded automatically and the consequences of such declaration shall be annulled. No such rescission or annulment shall affect any subsequent Default or impair any right consequent thereon. 

  
 25 








 Section 5.03 Waiver of Past Defaults. The Holders, either (a) through the
written consent of not less than a majority in aggregate principal amount of the outstanding Debentures or (b) by the adoption of a resolution, at a meeting of Holders of the outstanding Debentures at which a quorum is present, by the Holders
of at least a majority in aggregate principal amount of the outstanding Debentures, may, on behalf of the Holders of all of the Debentures, waive a past Default or Event of Default and its consequences, except a Default or Event of Default: 

(a) in the payment of the principal of or interest on any Debenture when due; 

(b) in respect of the right to convert any Debenture in accordance with Article 8 or to deliver shares of Common Stock due upon conversion of
any Debenture; 
 (c) in the payment of the Fundamental Change Repurchase Price on the Fundamental Repurchase Date in connection with the
repurchase right under Section 9.01 hereof; or 
 (d) in respect of compliance with a covenant or provision hereof which, under Section 6.02
hereof, may not be modified or amended without the consent of the Holder of each outstanding Debenture affected thereby. 
 Upon any such
waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; provided, however, that no such waiver shall extend to any subsequent or
other Default or impair any right consequent thereon. 
 Section 5.04 Limitation on Suits. 

Except in the case of a Default in the payment of principal or interest when due, no Holder may pursue any remedy with respect to this
Indenture or the Debentures unless: 
 (a) the Holder gives to the Trustee written notice stating that an Event of Default is continuing;

 (b) the Holders of at least 25% in aggregate principal amount of the outstanding Debentures make a written request to the Trustee to
pursue the remedy; and offer security or indemnity reasonably satisfactory to the Trustee against any loss, cost, liability or expense of the Trustee; 

(c) the Trustee does not comply with the request within 60 calendar days after receipt of the request and the offer of indemnity; and 

(d) the Holders of a majority in principal amount of the Debentures do not give the Trustee a direction inconsistent with the request during
such 60 day period. 
 A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority
over another Holder. 
 Section 5.05 Unconditional Rights of Holders to Receive Payment and to Convert. In addition to the other
rights and remedies set forth in this Article 5, notwithstanding any other provision in this Indenture, the Holder of any Debenture shall have the right, which is absolute and unconditional and shall not be impaired or affected without the consent
of such Holder, to receive payment of the principal amount, Fundamental Change Repurchase Price or interest, if any, in respect of the Debentures held by such Holder, on or after the respective due dates expressed in the Debentures and this
Indenture, and to convert such Debenture in accordance with Article 8 hereof, and to bring suit for the enforcement of any such payment on or after such respective due dates or for the right to convert in accordance with Article 8 hereof. 

Section 5.06 Additional Interest. 

(a) If, at any time during the six-month period beginning on, and including, the date that is six months after the Issue Date of the
Debentures, the Company fails to file any report that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (other than reports on Form 8-K) and the Company does not cure such failure to file within 14
calendar days after the last deadline for filing such report under Rule 12b-25 of the Exchange Act, the Company shall pay Additional Interest on the Debentures from, and including, both the last deadline for the report the Company failed to file to
and the earlier of (x) the date on which the Company files such reports or (y) the Free Trade Date. 

  
 26 








 (b) The Company shall also pay Additional Interest on the Debentures if all of the outstanding
Non-Commitment Debentures, excluding any Debentures held by a Person that is an Affiliate or has been held by an Affiliate during the three months prior to the Free Trade Date, do not become Freely Tradeable within one calendar week after the Free
Trade Date, or the next succeeding Business Day if such date is not a Business Day, for the period from, and including, the Free Trade Date until the date on which such Debentures become Freely Tradeable. For the avoidance of doubt, any Additional
Debentures issued with different restricted CUSIP numbers will be treated separately, but will be subject to equivalent provisions, for purposes of this Section 5.06(b), as set forth in Section 2.07(a)(viii). 

(c) Additional Interest payable pursuant to Section 5.06(a) and Section 5.06(b) shall accrue at a rate of 0.50% of the principal amount of the
Debentures per annum. In no event shall Additional Interest accrue under the terms of this Indenture (aggregating any Additional Interest payable pursuant to this Section 5.06 with any Additional Interest payable pursuant to Section 5.07) at a rate
per year in excess of 0.50% of the principal amount of the Debentures, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest. 

(d) Accrued Additional Interest shall be payable on the same dates and in the same manner as interest is paid of the Debentures pursuant to
Section 2.03 of this Indenture. Subject to Section 5.06(e), the accrual of Additional Interest shall fulfill all of the Company’s obligations to Holders for the failure of the Debentures to be Freely Tradeable. 

(e) If the Company is required to pay Additional Interest pursuant to Section 5.06(b), the Company may elect to designate an effective
registration statement for the resale of the applicable Debentures and the shares of Common Stock issuable upon conversion of such Debentures. Notwithstanding Section 5.06(b), for each day on which such shelf registration statement remains effective
and usable by Holders for the resale of the applicable Debentures and the shares of Common Stock issuable upon conversion of such Debentures, Additional Interest shall not accrue and the Company shall have no obligation to Holders for failing to
make the Debentures Freely Tradeable during such time period. Any such registration shall be effected on terms customary for the resale of debentures and shares of common stock generally offered in reliance upon Rule 144A. After the Company has made
such a registration statement available for a period of two years, the Company’s obligation to pay Additional Interest under this Section 5.06 as a result of the failure of the Debentures to become Freely Tradeable by the Free Trade Date,
pursuant to Section 5.06(b), shall terminate. 
 Section 5.07 Failure to Comply with Reporting Covenants. 

(a) To the extent the Company so elects, the sole remedy to Holders for the Company’s failure to comply with the reporting obligations
pursuant to Section 3.06 hereof (the “Reporting Obligations”), shall, for the first 365 days after the occurrence of such Event of Default, consist of the right to receive Additional Interest on the Debentures at an annual rate
equal to 0.50% of the principal amount of the Debentures. Additional Interest shall accrue on all outstanding Debentures during which such Event of Default is continuing from, and including, the date on which such Event of Default first occurs to,
but excluding, the 365th day thereafter (or such earlier date on which such Event of Default shall have been cured or waived). On such 365th day (or earlier, if such Event of Default cured or waived prior to such 365th day), such Additional Interest
shall cease to accrue and, if the such Event of Default has not been cured or waived prior to such 365th day, the Debentures will be subject to a Fundamental Change under Section 9.01. Filing of a report shall constitute a cure of any failure to
file or deliver such report on a timely basis. In the event the Company does not pay Additional Interest upon an Event of Default relating to its Reporting Obligations in accordance with this Section 5.07, the Debentures will be subject to
acceleration as provided in Section 5.02. 
 (b) If the Company elects to pay Additional Interest in connection with a failure to comply
with its Reporting Obligations, the Company shall notify all Holders and the Trustee and Paying Agent on or before the close of business on the date on which such Event of Default first occurs. The Company shall deliver to the Trustee an
Officer’s Certificate to that effect stating (x) the amount of such Additional Interest that is payable and (y)

  
 27 








 
the date on which such Additional Interest is payable. Unless and until a responsible officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume
without inquiry that no such Additional Interest is payable. If the Company has paid Additional Interest directly to the Persons entitled to it, the Company shall deliver to the Trustee an Officer’s Certificate setting forth the particulars of
such payment. For the avoidance of doubt, the maximum amount of Additional Interest to be paid under Section 5.06 or this Section 5.07 for any reason is 0.50% of the principal amount of the Debentures per annum, which shall constitute the sole
remedy for the Company’s obligations to pay Additional Interest. Additional Interest pursuant to this Section 5.07(b) will be payable in arrears on each Interest Payment Date in the same manner as interest on the Debentures pursuant to Section
2.03 hereof. 
 Section 5.08 Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if:

 (a) default is made in the payment of any interest on any Debenture when such interest becomes due and payable and such default continues
for a period of 60 days, or 
 (b) default is made in the payment of principal of any Debenture within three Business Days of its Maturity
thereof, or 
 then, the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Debentures, the whole amount then due
and payable on such Debentures for principal and interest and, to the extent legally enforceable, interest on any overdue principal or any overdue interest and, in addition thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Debentures and collect the moneys
adjudged or deemed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Debentures, wherever situated. 

If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of
the Holders by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of
any power granted herein, or to enforce any other proper remedy. 
 Section 5.09 Trustee May File Proofs of Claim. In case of
the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Debentures or the property of the Company
or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Debentures shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have
made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise, 

(a) to file and prove a claim for the whole amount of principal and interest owing and unpaid in respect of the Debentures and to file such
other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the
Holders allowed in such judicial proceeding, and 
 (b) to collect and receive any moneys or other property payable or deliverable on any
such claims and to distribute the same, and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and,
in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel,
and any other amounts due the Trustee hereunder. 

  
 28 








 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Debentures 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 5.10 Trustee May Enforce Claims Without Possession of Debentures. All rights of action and claims under
this Indenture or the Debentures may be prosecuted and enforced by the Trustee without the possession of any of the Debentures or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders in respect of which such judgment has been recovered. 
 Section 5.11 Application of Money
Collected. Any money collected by the Trustee pursuant to this Article 5 shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or interest, upon
presentation of the Debentures and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

First: To the payment of all amounts due the Trustee and each Agent hereunder; and 

Second: To the payment of the amounts then due and unpaid for principal of and interest on the Debentures in respect of which or for the
benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Debentures for principal and interest, respectively; and 

Third: To the Company. 

  
 29 








 Section 5.12 Restoration of Rights and Remedies. If the Trustee or any Holder has
instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case,
subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall
continue as though no such proceeding had been instituted. 
 Section 5.13 Rights and Remedies Cumulative. Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debentures in Section 2.08, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other
right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 

Section 5.14 Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article 5 or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 

Section 5.15 Control by Holders. The Holders of a majority in principal amount of the outstanding Debentures shall have the right to
direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Debentures, provided that: 

(a) such direction shall not be in conflict with any rule of law or with this Indenture, 

(b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and 

(c) subject to the provisions of Section 5.01, the Trustee shall have the right to decline to follow any such direction if the Trustee in good
faith, by a Trust Officer of the Trustee, determines that the proceeding so directed would involve the Trustee in personal liability. 

Section 5.16 Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Debenture by his acceptance
thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as
Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 5.16 shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any
suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the outstanding Debentures, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or interest
on any Debenture on or after the Maturity Date (or, in the case of redemption, on the Redemption Date). 
 Article 6 

Amendments; Supplements and Waivers  

Section 6.01 Without Consent of Holders. 

The Company and the Trustee may modify, amend or supplement this Indenture or the Debentures without notice to or consent of any Holder of a
Debenture for any of the following purposes: 
 (a) to provide for conversion rights of Holders and the Company’s repurchase obligations
in connection with a Fundamental Change in the event of any reclassification of the Common Stock, merger or consolidation, or sale, conveyance, transfer or lease of the Company’s property and assets substantially as an entirety to the extent
provided in Section 8.05 hereof; 

  
 30 








 (b) to secure the Debentures;

the event of a merger or consolidation, or sale, conveyance, transfer or lease of the Company’s property and assets substantially as an entirety;

interests of the Holders in any material respect; 
 (h) to increase the Conversion Rate; 

(i) to comply with the requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA;

Section 6.02 With Consent of Holders.

quorum is present, by the Holders of a majority in aggregate principal amount of the outstanding Debentures. 
 Without the written consent
or the affirmative vote of each Holder affected, an amendment or waiver under this Section 6.02 may not: 
 (a) extend the maturity of any
Debentures; 
 (b) reduce the rate or extend the time for payment of interest on any Debentures; 

(c) reduce the principal amount of any Debentures; 

(d) reduce any amount payable upon repurchase of any Debentures in accordance with Article 9 or redemption of the Debentures in accordance

adverse to the Holders after the occurrence of a Fundamental Change; 
 (j) affect the right of a Holder to convert any Debentures pursuant

 (k) change the Company’s obligation to maintain an agency for service of process in New York City;

(m) reduce the percentage of the Debentures required for consent to any modification of this Indenture that does not require the consent of
each affected Holder. 
 It shall not be necessary for any act of Holders under this Section 6.02 to approve the particular form of any
proposed supplemental indenture, but it shall be sufficient if such act shall approve the substance thereof. 
 After an amendment,
supplement or waiver under Section 6.01 or this Section 6.02 becomes effective, the Company shall promptly mail or deliver electronically to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to deliver such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver. 

Section 6.03 Compliance with Trust Indenture Act. 

Every amendment to this Indenture or the Debentures shall be set forth in a supplemental indenture hereto that complies with the TIA as then
in effect. 
 Section 6.04 Revocation and Effect of Consents. 

Until an amendment or waiver becomes effective, a consent to it by a Holder of a Debenture is a continuing consent by the Holder and every
subsequent Holder of a Debenture or portion of a Debenture that evidences the same Debt as the consenting Holder’s Debenture, even if notation of the consent is not made on any Debenture. However, any such Holder or subsequent Holder may revoke
the consent as to his Debenture or portion of a Debenture if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective. 

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or
take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at such record date (or their
duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. 

  
 32 








 Section 6.05 Notation on or Exchange of Debentures. 

The Trustee may place an appropriate notation about an amendment or waiver on any Debenture thereafter authenticated. The Company, in exchange
for Debentures, may issue new Debentures that reflect the amendment or waiver date, which the Trustee shall authenticate upon receipt of a Company Order. 

Section 6.06 Trustee Protected. 

In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article 6 or the modifications
thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and, subject to Section 7.01, shall be fully protected in conclusively relying upon, an Officer’s Certificate and an Opinion of Counsel stating that the
execution of such supplemental indenture is authorized or permitted by this Indenture and that such supplemental indenture is the valid, legal and binding obligation of the Company and any guarantor, as applicable, enforceable in accordance with its
terms. The Trustee, subject to the terms hereof, shall sign all supplemental indentures, except that the Trustee need not sign any supplemental indenture that adversely affects its rights, duties or immunities.

matters as it may see fit. 
 (g) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this

may be incurred therein or thereby.

(m) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

 Section 7.03 Individual Rights of Trustee. 

The Trustee in its individual or any other capacity may become the owner or pledgee of Debentures and may otherwise deal with the Company or
an Affiliate with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. The Trustee is also subject to Section 7.09 and Section 7.10. 

Section 7.04 Trustee’s Disclaimer. 

The Trustee shall not be responsible and makes no representation as to the validity or adequacy of this Indenture or the Debentures, it shall
not be accountable for the Company’s use of the proceeds from the Debentures, and it shall not be responsible for any statement in the Debentures or in any document issued in connection with the sale of the Debentures or in the Debentures other
than its certificate of authentication. 
 Section 7.05 Reports by Trustee to Holders. 

As promptly as practicable after each November 15 beginning with November, 2016, and in any event prior to December 15 in each year,
the Trustee shall transmit by mail to all Holders, as their names and addresses appear on the Register, a report dated as of November 15 of each year in such manner and to the extent required by TIA § 313(a). The Trustee shall also comply
with TIA § 313(b) and TIA § 313(c). 
 A copy of each report at the time of its mailing to Holders shall be filed with the SEC and
each stock exchange (if any) on which the Debentures are listed. The Company shall promptly notify the Trustee when Debentures are listed on any stock exchange and of any delisting thereof. 

Section 7.06 Compensation and Indemnity. 

The Company shall pay to the Trustee, acting in any capacity hereunder, from time to time such compensation as the Company and the Trustee
shall from time to time agree in writing. Such compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or
made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and
experts. The Company shall indemnify the Trustee, acting in any capacity hereunder, defend and hold it harmless, against any and all loss, liability, damages, costs or expense (including reasonable attorneys’ fees) incurred by or in connection
with the offer and sale of the Debentures or the administration of this trust and the performance of its duties hereunder. The Trustee shall notify the Company of any claim for which it may seek indemnity promptly upon obtaining actual


  
 35 








 
knowledge thereof; provided, however, that any failure so to notify the Company shall not relieve the Company of its indemnity obligations hereunder. The Company shall defend the claim and
the indemnified party shall provide reasonable cooperation at the Company’s expense in the defense. Such indemnified parties may have separate counsel and the Company shall pay the fees and expenses of such counsel; provided, however,
that the Company shall not be required to pay such fees and expenses if it assumes such indemnified parties’ defense and, in such indemnified parties’ reasonable judgment, there is no conflict of interest between the Company and such
parties in connection with such defense. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by an indemnified party through such party’s own willful misconduct and negligence. 

To secure the Company’s payment obligations in this Section 7.06, the Trustee shall have a lien prior to the Debentures on all money or
property held or collected by the Trustee. 
 The Company’s payment obligations and indemnification pursuant to this Section 7.06 shall
survive the satisfaction or discharge of this Indenture, any rejection or termination of this Indenture under Bankruptcy Law or the resignation or removal of the Trustee. 

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 5.01(g) or Section 5.01(h) occurs, the
expenses and the compensation for the services are intended to constitute expenses of administration under Bankruptcy Law. 

Section 7.07 Replacement of Trustee. 

(a) The Trustee may resign at any time by so notifying the Company. The Holders of a majority in principal amount of the Debentures may remove
the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee if: 
 (i)
the Trustee fails to comply with Section 7.09; 
 (ii) the Trustee is adjudged bankrupt or insolvent; 

(iii) a receiver or other public officer takes charge of the Trustee or its property; or 

(iv) the Trustee otherwise becomes incapable of acting. 

(b) If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal amount of the Debentures and the Holders do
not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee. The successor Trustee shall mail a notice of its succession to each Holder. The retiring
Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.06. 

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the
Holders of 10% in principal amount of the Debentures may petition any court of competent jurisdiction for the appointment of a successor Trustee. 

If the Trustee fails to comply with Section 7.09, any Holder may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee. 

  
 36 








 Notwithstanding the replacement of the Trustee pursuant to this Section 7.07, the Company’s
obligations under Section 7.06 shall continue for the benefit of the retiring Trustee. The retiring or any removed Trustee shall bear no liability or responsibility for the action or inaction of any successor Trustee. 

Section 7.08 Successor Trustee by Merger, Etc. 

If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business or assets to,
another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee. 

In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by
this Indenture any of the Debentures shall have been authenticated but not delivered, any such successor to such Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Debentures so authenticated; and in
case at that time any of the Debentures shall not have been authenticated, any successor to the Trustee may authenticate such Debentures either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such
cases such certificates shall have the full force which it is anywhere in the Debentures or in this Indenture provided that the certificate of the Trustee shall have. 

Section 7.09 Eligibility; Disqualification. 

The Trustee shall, at all times, satisfy the requirements of TIA § 310(a). The Trustee shall have a combined capital and surplus of at
least $ 50,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with TIA § 310(b); provided, however, that there shall be excluded from the operation of TIA § 310(b)(1) any indenture
or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in TIA § 310(b)(1) are met. 

Section 7.10 Preferential Collection of Claims Against Company. 

The Trustee shall comply with TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned
or been removed shall be subject to TIA § 311(a) to the extent indicated. 
 Article 8 

Conversion of Debentures 

Section 8.01 Conversion Privilege. Subject to and upon compliance with the provisions of this Indenture, each Holder shall have
the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Debenture at any time prior to the close of business on the Business Day
immediately preceding the Maturity Date at an initial conversion rate of 32.7568 shares of Common Stock (subject to adjustment as provided in this Article 8, the “Conversion Rate”) per $1,000 principal amount of Debentures (subject
to, and in accordance with, the settlement provisions of Section 8.02, the “Conversion Obligation”). 
 Section 8.02
Conversion Procedures; Settlement Upon Conversion. 
 (a) In order to exercise the conversion right with respect to any Debentures in
certificated form, a Holder must (i) complete and manually sign an irrevocable notice of conversion in the Form of Conversion Notice attached to the reverse of such certificated Debenture (or a facsimile thereof) (a “Conversion
Notice”); (ii) deliver such completed Conversion Notice and certificated Debenture to be converted to the Conversion Agent at the office of the Conversion Agent; (iii) if required, furnish appropriate endorsements and transfer
documents as may be required by the Conversion Agent; and (iv) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled. The Company shall pay any documentary, stamp or similar
issue or transfer tax on the issuance of any shares of Common Stock upon conversion of Debentures, unless such tax is due because a Holder requests such shares to be issued in a name other than such Holder’s name, in which case such Holder
shall pay such tax. Once delivered, a Conversion Notice is irrevocable. 

  
 37 








 (b) In order to exercise the conversion right with respect to a beneficial interest in a Global
Debenture, the Holder must (i) comply with the Applicable Procedures for converting a beneficial interest in a Global Debenture; (ii) pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not
entitled, if required; and (iii) pay the funds, if any, required by this Section 8.02 and any transfer or similar taxes or duties, if required. Delivery of instructions with respect to Global Debentures are irrevocable. 

(c) A Debenture shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion
Date”) that a Holder has complied with the requirements set forth above in clause (a) or (b), as the case may be, in this Section 8.02. 

(d) Upon conversion of any Debenture, the Company shall deliver to the converting Holder, in respect of each $1,000 principal amount of
Debentures being converted, a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date, together with a cash payment, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with
subsection (l) of this Section 8.02, on the third Business Day immediately following the relevant Conversion Date. 
 (e) The Company shall
issue or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of shares of Common Stock to which such
Holder shall be entitled in satisfaction of the Company’s Conversion Obligation. 
 (f) If more than one Debenture shall be surrendered
for conversion at one time by the same Holder, the Conversion Obligation with respect to such Debentures shall be computed on the basis of the aggregate principal amount of the Debentures (or specified portions thereof to the extent permitted
thereby) so surrendered. 
 (g) In case any Debentures of a denomination greater than $1,000 shall be surrendered for partial conversion,
and subject to Section 2.03 hereof, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of the Debentures so surrendered, without charge to the Holder, a new Debenture or Debentures in authorized denominations in
an aggregate principal amount equal to the unconverted portion of the surrendered Debentures. 
 (h) Any Debenture or portion thereof
surrendered for conversion during the period from the close of business on the Regular Record Date for an Interest Payment to the close of business on the corresponding Interest Payment Date, shall be accompanied by payment, in immediately available
funds or other funds acceptable to the Company, of an amount equal to the interest that has accrued and would be paid on such Interest Payment Date on the principal amount be converted; provided that no such payment shall be required (i) in
connection with conversions of Debentures following the Regular Record Date immediately preceding the Maturity Date, (ii) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to
the corresponding Interest Payment Date, or, if later, the Business Day on which such interest is payable pursuant to Section 13.07, (iii) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the
corresponding Interest Payment Date or (iv) to the extent of any overdue interest, if any, that exists at the time of conversion with respect to such Debentures. For the avoidance of doubt, all record Holders at the close of business on the
Regular Record Date immediately preceding the Maturity Date and any Fundamental Change Repurchase Date will receive the full interest payment due on the Maturity Date or Fundamental Change Repurchase Date, regardless of whether their Debentures have
been converted following such Regular Record Date and converting Holders shall not be required to make an equivalent payment upon conversion. Except as provided above in this Section 8.02 and below in Section 8.04, no separate cash payment or other
adjustment shall be made for interest accrued and unpaid on any Debenture converted or for dividends on any shares of Common Stock. 
 (i)
Upon the conversion of an interest in a Global Debenture, the Trustee (or other Conversion Agent appointed by the Company), or the custodian for the Global Debenture at the direction of the Trustee (or other Conversion Agent appointed by the
Company), shall make a notation on such Global Debenture as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversions of Debentures effected through any Conversion Agent other
than the Trustee. 

  
 38 








 (j) Subject to Section 2.03 hereof, the Company’s settlement of the full Conversion
Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Debenture and accrued and unpaid interest, if any, to, but excluding, the Conversion Date. Subject to Section 2.03 hereof, upon the conversion of any
Debentures, the accrued but unpaid interest, if any, attributable to the period from the Issue Date of the Debentures to, but excluding, the Conversion Date, with respect to the converted Debentures, shall not be cancelled, extinguished or
forfeited, but rather shall be deemed to be paid in full to the Holder thereof by the Company’s settlement of the full Conversion Obligation. 

(k) Each conversion shall be deemed to have been effected as to any Debenture (or portion thereof) surrendered for conversion on the
Conversion Date. The Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a stockholder of record as of the close of business on the relevant Conversion Date. Upon a
conversion of Debentures, such Person shall no longer be a Holder of such Debentures surrendered for conversion. 
 (l) The Company shall
not issue any fractional shares of Common Stock upon conversion of the Debentures and shall instead pay cash in lieu of delivering any fractional shares of Common Stock issuable upon conversion based on the Closing Sale Price of the Common Stock on
the relevant Conversion Date. 
 Section 8.03 Adjustment to Conversion Rate Upon a Non-Stock Change of Control. 

(a) Prior to the Maturity Date, if and only to the extent a Holder elects to convert Debentures in connection with a Non-Stock Change
of Control, at any time beginning on the Business Day following the date on which such Non-Stock Change of Control becomes effective (the “Effective Date”) but before the close of business on the Business Day immediately preceding
the related Fundamental Change Repurchase Date (such period, the “Non-Stock Change of Control Fundamental Change Conversion Period”), the Company shall increase the Conversion Rate applicable to such converted Debentures as
described in clause (b) of this Section 8.03. A conversion of Debentures shall be deemed to be “in connection with” a Non-Stock Change of Control if the Conversion Notice is received by the Conversion Agent during the period specified
in the previous sentence.  
 (b) If a Holder elects to convert its Debentures in connection with a Non-Stock Change of Control, the
Conversion Rate at which such Debentures will be converted will be calculated as set out below, adjusted in the same manner as and as of any date on which the Conversion Rate is adjusted as set forth in Section 8.04. 

 
 



 
 where, 

					
			
	 CRFC
	  	=    	  	the Conversion Rate on a Conversion Date taking place during the Non-Stock Change of Control Fundamental Change Conversion Period for any conversion of Debentures in connection with a Non-Stock Change of Control Fundamental
Change;
			
	 RR
	  	=    	  	the Reference Conversion Rate;
			
	 CCR
	  	=    	  	the Conversion Rate that would otherwise be in effect on the relevant Conversion Date pursuant to the terms of the Debentures;
			
	 N
	  	=    	  	The number of calendar days from (and including) December 15, 2015 to (but excluding) January 15, 2023;
			
	 n
	  	=    	  	the number of calendar days from (and including) December 15, 2015 to (but excluding) the Effective Date.



  
 39 








 “Reference Conversion Rate” means a conversion rate equal to 43.4027 shares
of the Common Stock per $1,000 principal amount of Debentures, adjusted in the same manner as and as of any date on which the Conversion Rate is adjusted as set forth in Section 8.04. Notwithstanding anything in this Indenture to the contrary, in no
event shall the Conversion Rate be increased to more than 43.4027 shares of Common Stock per $1,000 principal amount of Debentures pursuant to the events described in this Section 8.03, subject to adjustment in the same manner as the Conversion Rate
pursuant to Section 8.04. 
 (c) The Company shall provide written notice to all Holders and to the Trustee as soon as practicable and if
possible at least 20 calendar days prior to the anticipated Effective Date of a Non-Stock Change of Control (but in no event earlier than the date the Company publicly announces such transaction (the “Announcement Date”);
provided, that if the Announcement Date is fewer than 20 calendar days prior to the anticipated Effective Date, it shall nonetheless be at least 10 calendar days prior to the anticipated Effective Date and, in such a case, on the day the
Company provides such notice, the Company will also issue a press release containing the relevant information of such Non-Stock Change of Control (and make such press release available on the Company’s website). The Company must also provide
written notice to all Holders and to the Trustee upon the effectiveness of such Non-Stock Change of Control. 
 (d) Nothing in this Section
8.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 8.04 in respect of a Non-Stock Change of Control. 

Section 8.04 Conversion Rate Adjustments. The Conversion Rate shall be adjusted from time to time as follows: 

(a) In case (i) the Company shall, at any time, or from time to time, while any of the Debentures are outstanding, issue solely shares of
Common Stock as a dividend or distribution on all, or substantially all, of its shares of the Common Stock or (ii) the outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock or combined into a
smaller number of shares of Common Stock, the Conversion Rate shall be adjusted based on the following formula: 
  
 



 
 where, 

					
			
	 CR0
	  	=    	  	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such dividend or distribution, or immediately prior to the open of business on the Effective Date of such subdivision or combination
of Common Stock, as the case may be;
			
	 CR1
	  	=    	  	the Conversion Rate in effect immediately after the close of business on the Record Date for such dividend or distribution, or immediately after the open of business on the Effective Date of such subdivision or combination of
Common Stock, as the case may be;
			
	 OS0
	  	=    	  	the number of shares of Common Stock outstanding immediately prior to the close of business on the Record Date for such dividend or distribution, or immediately prior to the open of business on the Effective Date of such
subdivision or combination of Common Stock, as the case may be; and
			
	 OS1
	  	=    	  	the number of shares of Common Stock outstanding immediately after such dividend or distribution, or immediately after the Effective Date of such subdivision or combination of Common Stock, as the case may be.



  
 40 








 Any adjustment made under this Section 8.04(a) shall become effective immediately after the close
of business on the Record Date for such dividend or distribution, or immediately after the open of business on the Effective Date of such share split or share combination. In the event that any dividend or distribution of the type described in this
Section 8.04(a) is declared but not so paid, the Conversion Rate shall be immediately readjusted, effective as of the date an Independent Committee determines not to pay such dividend or distribution, to the Conversion Rate that would then be in
effect if such dividend, distribution had not been declared. For the purpose of this Section 8.04(a), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. The Company shall not
pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. 
 (b) In case the Company shall
issue to all or substantially all holders of Common Stock any rights, options or warrants entitling them for a period of not more than 45 calendar days from the Record Date for such distribution to subscribe for or purchase shares of Common Stock,
at a price per share less than the average of the Closing Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution (excluding
(i) dividends or distributions (including subdivision of the Common Stock) as to which an adjustment was effected pursuant to Section 8.04(a) above, and (ii) distributions of rights to all or substantially all holders of Common Stock
pursuant to the adoption of a shareholders rights plan), the Conversion Rate shall be increased based on the following formula (provided that the Conversion Rate shall be readjusted to the extent that such rights, options or warrants are not
exercised prior to their expiration or are not distributed): 
  
 



 
 where, 

					
			
	 CR0
	  	=    	  	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such distribution;
			
	 CR1
	  	=    	  	the Conversion Rate in effect immediately after the close of business on the Record Date for such distribution;
			
	 OS0
	  	=    	  	the number of shares of Common Stock outstanding immediately prior to the close of business on the Record Date for such distribution;
			
	 X
	  	=    	  	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
			
	 Y
	  	=    	  	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day
period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution.


 For purposes of this Section 8.04(b), in determining whether any rights, options or warrants entitle the
Holders to subscribe for or purchase shares of Common Stock at less than the average of the Closing Sale Prices of the Common Stock, for each Trading Day in the applicable 10 consecutive Trading Day period, there shall 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 other than cash) to be determined by an Independent Committee. 

Any increase made under this Section 8.04(b) shall be effective immediately after the close of business on the Record Date for such
distribution. To the extent such rights, options or warrants are not exercised prior to their expiration or termination, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the decrease with respect to the
distribution of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so distributed, the Conversion Rate shall be decreased
to the Conversion Rate that would then be in effect if such Record Date for such distribution had not occurred. 

  
 41 








 (c) In the case the Company shall distribute to all or substantially all holders of any class of
Common Stock shares of any class of Capital Stock of the Company, evidences of its Debt or other assets or property of the Company (excluding (i) dividends or distributions (including subdivision of Common Stock) and rights, options or warrants
as to which an adjustment was effected pursuant to Section 8.04(a) or Section 8.04(b) above; (ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 8.04(d) below;
(iii) Spin-Offs referred to further below in this Section 8.04(c); and (iv) distributions of rights to all or substantially all holders of Common Stock pursuant to the adoption of a shareholder rights plan), then the Conversion Rate shall
be increased based on the following formula: 
  
 



 
 where, 

					
			
	 CR0
	  	=    	  	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such distribution;
			
	 CR1
	  	=    	  	the Conversion Rate in effect immediately after the close of business on the Record Date for such distribution;
			
	 SP0
	  	=    	  	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and
			
	 FMV
	  	=    	  	the fair market value (as determined by an Independent Committee) of the shares of Capital Stock, evidences of Debt, assets or property distributed with respect to each outstanding share of Common Stock as of the open of business
on the Ex-Dividend Date for such distribution.


 If the “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing adjustment, adequate provisions shall be made so that each Holder shall have the right to receive on conversion in respect of each Debenture held
by such Holder, in addition to the shares of Common Stock to which such Holder is entitled to receive, the amount and kind of securities and assets such Holder would have received had such Holder already owned a number of shares of Common Stock
equal to the Conversion Rate immediately prior to the close of business on the Record Date for the distribution of the securities or assets. Any increase made under the first paragraph of this Section 8.04(c) will become effective immediately after
the close of business on the Record Date of such distribution. If such distribution is not so paid or made, or if any rights, options or warrants are not exercised before their expiration date, the Conversion Rate shall be decreased to the
Conversion Rate that would then be in effect if such dividend or distribution had not been made. 
 With respect to an adjustment
pursuant to this Section 8.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary, listed on a U.S.
national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula:  
  





 
 where, 

					
			
	 CR0
	  	=    	  	the Conversion Rate in effect immediately prior to the close of business on the Record Date for the Spin-Off;



  
 42 








 
					
			
	 CR1
	  	=    	  	the Conversion Rate in effect immediately after the close of business on the Record Date for the Spin-Off;
			
	 FMV
	  	=    	  	the average of the Closing Sale Prices of the Capital Stock or similar equity interests distributed to holders of Common Stock applicable to one share of Common Stock (determined by reference to the definition of Closing Sale
Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period immediately following, and including, the Ex-Dividend Date for the
Spin-Off (such period, the “Spin-Off Valuation Period”); and
			
	 MP0
	  	=    	  	the average of the Closing Sale Prices of the Common Stock over the Spin-Off Valuation Period.


 The increase to the Conversion Rate under the preceding paragraph of this Section 8.04(c) shall be made
immediately after the open of business on the day after the last day of the Spin-Off Valuation Period, but shall be given effect as of the close of business on the Record Date for the Spin-Off. For purposes of determining the Conversion Rate, in
respect of any conversion during the Spin-Off Valuation Period, references within the portion of this Section 8.04(c) related to “Spin-Offs” to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have
elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, but excluding, the relevant Conversion Date. 
 For purposes of this
Section 8.04(c) (and subject in all respects to Section 8.08), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock,
including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such
shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 8.04(c) (and no adjustment to the
Conversion Rate under this Section 8.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required)
to the Conversion Rate shall be made under this Section 8.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the
occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of Debt or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution
and Record Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In
addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes
of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 8.04(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by
any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to
such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Common Stock with respect to such rights,
options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have
expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued. 

For purposes of Section 8.04(a), Section 8.04(b) and this Section 8.04(c), if any dividend or distribution to which this Section 8.04(c) is
applicable also includes one or both of: 
 (A) a dividend or distribution of shares of Common Stock to which Section 8.04(a) is applicable
(the “Clause A Distribution”); or 

  
 43 








 (B) a dividend or distribution of rights, options or warrants to which Section 8.04(b) is
applicable (the “Clause B Distribution”), 
 then, in either case, (1) such dividend or distribution, other than the Clause A
Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 8.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section
8.04(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by
Section 8.04(a) and Section 8.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Record Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Record
Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the close of business on the Record Date for such
dividend or distribution, or immediately prior to the open of business on the Effective Date of such subdivision or combination of Common Stock, as the case may be” within the meaning of Section 8.04(a) or “outstanding immediately prior to
the close of business on the Record Date for such distribution” within the meaning of Section 8.04(b). 
 (d) In case the Company shall
make or pay any cash dividend or distribution to all, or substantially all, holders of Common Stock (other than distributions described to in Section 8.04(e) below), the Conversion Rate shall be increased based on the following formula: 

 
 



 
 where, 

					
			
	 CR0
	  	=    	  	the Conversion Rate in effect immediately prior to the close of business on the Record Date for such distribution;
			
	 CR1
	  	=    	  	the Conversion Rate in effect immediately after the close of business on the Record Date for such distribution;
			
	 SP0
	  	=    	  	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and
			
	 C
	  	=    	  	the amount in cash per share the Company pays or distributes to holders of Common Stock.


 If “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing clause, each Holder shall receive, for each $1,000 principal amount of Debentures, at the same time and upon the same terms as holders of shares
of Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect immediately prior to the close of business on the Record Date for such cash
dividend or distribution. 
 The adjustment to the Conversion Rate under this Section 8.04(d) shall become effective immediately after the
close of business on the Record Date for such dividend or distribution. If any dividend or distribution described in this Section 8.04(d) is declared but not so paid or made, or is reduced, the new Conversion Rate shall be decreased to the
Conversion Rate that would then be in effect if such dividend or distribution had not been declared, or had been declared as so reduced. 

  
 44 








 (e) In case a payment in respect of a tender or exchange offer is made by the Company or any
Subsidiary of the Company for the Common Stock and the cash and value of any other consideration included in the payment per share of Common Stock exceeds the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day
period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Expiration Date”), the Conversion Rate shall be increased
based on the following formula: 
  
 



 
 where, 

					
			
	 CR0
	  	=    	  	the Conversion Rate in effect immediately prior to the open of business on the Trading Day next succeeding the Expiration Date;
			
	 CR1
	  	=    	  	the Conversion Rate in effect immediately after the open of business on the Trading Day next succeeding the Expiration Date;
			
	 AC
	  	=    	  	the aggregate value of all cash and any other consideration (as determined by an Independent Committee) paid or payable for shares of Common Stock purchased in such tender or exchange offer;
			
	 OS0
	  	=    	  	the number of shares of Common Stock outstanding immediately prior to the time (the “Expiration Time”) such tender or exchange offer expires (prior to giving effect to such tender offer or exchange
offer);
			
	 OS1
	  	=    	  	the number of shares of Common Stock outstanding immediately after the Expiration Time (after giving effect to such tender offer or exchange offer); and
			
	 SP1
	  	=    	  	the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Expiration Date.


 The increase to the Conversion Rate under the preceding paragraph of this Section 8.04(e) shall be given
effect at the open of business on the Trading Day next succeeding the Expiration Date. For purposes of determining the Conversion Rate, in respect of any conversion during the 10 Trading Days commencing on the Trading Day next succeeding the
Expiration Date, references within this Section 8.04(e) to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, but excluding,
the relevant Conversion Date. 
 (f) Notwithstanding anything in this Section 8.04 to the contrary, if a Conversion Rate adjustment becomes
effective as described in this Section 8.04, and a Holder that has converted its Debentures on or after the relevant Ex-Dividend Date and on or prior to the related Record Date would be treated as the record Holder of Common Stock as of the related
Conversation Date as provided in Section 8.02 hereof based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the foregoing Conversation Rate provisions, the Conversion Rate adjustment relating to such Ex-Dividend Date
shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to
such adjustment. The Company, in its sole discretion, may (but is not required to) increase the Conversion Rate as an Independent Committee considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to
purchase shares of Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or any event treated as such for income tax purposes. 

(g) To the extent permitted by applicable law, the Company, from time to time, may increase the Conversion Rate by any amount for any period
of time at least 20 Business Days so long as the increase is irrevocable during the period and an Independent Committee shall have made a determination that such increase would be in the best interest of the Company, which determination shall be
conclusive. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall deliver to Holders of record of the Debentures, the Trustee and the Conversion Agent a notice of the increase, which notice shall be given at
least 15 days prior to the effectiveness of any such increase, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. 

  
 45 








 The Company shall not take any action that would result in adjustment of the Conversion Price,
pursuant to the provisions of this Section 8.04(g), in such a manner as to result in the reduction of the Conversion Price to less than the par value per share of Common Stock. 

(h) The Conversion Rate shall not be adjusted: 

(i) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of
dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any such plan; 

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

(iii) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or
convertible security not described in the preceding clause (ii) and outstanding as of the date the Debentures were first issued; or 

(iv) for accrued and unpaid interest, if any. 

(i) Notwithstanding anything in this Section 8.04 to the contrary, no adjustment in the Conversion Rate shall be required unless such
adjustment would result in a change of at least one percent (1%) in the Conversion Rate; provided, however, that any adjustments that by reason of this Section 8.04(i) are not required to be made shall be carried forward and the
Company shall make such carry forward adjustments, regardless of whether the aggregate adjustment is less than 1% of the Conversion Rate, (x) upon any conversion of Debentures, (ii) upon any required purchases of the Debentures in
connection with a Fundamental Change, and (iii) upon any redemption of the Debentures at the option of the Company pursuant to the terms of the Debentures and this Indenture. All calculations under this Article 8 shall be made by the Company
and shall be made to the nearest one-ten thousandth (1/10,000) of a share of Common Stock. 
 (j) Except as set forth in this Section
8.04 or in Section 8.03, the Company shall not adjust the Conversion Rate. 
 (k) Notwithstanding anything to the contrary herein, no
adjustment to the Conversion Rate need be made for a given transaction (other than a share split or share combination) if Holders participate, on the same terms and otherwise on the same basis and solely as a result of holding the Debentures, as
holders of Common Stock without having to convert their Debentures as if they held a number of shares of Common Stock equal to the then-current Conversion Rate, multiplied by the principal amount (expressed in thousands) of Debentures held by such
Holder. 
 (l) Whenever the Conversion Rate is adjusted as herein provided, the Company shall issue a press release through Business Wire or
another widely accepted business wire service containing the relevant information and make this information available on the Company’s website or through another public medium as the Company may use at that time. In addition, the Company shall
promptly file with the Trustee and any Conversion Agent other than the Trustee an Officer’s Certificate setting forth the Conversion Rate, detailing the calculation of the Conversion Rate and describing the facts upon which the adjustment is
based. Unless and until a Trust Officer of the Trustee shall have received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of
which it has actual knowledge is still in effect. 

  
 46 








 (m) For purposes of this Section 8.04, the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any
distribution on shares of Common Stock held in the treasury of the Company. 
 (n) Except as provided in this Article 8, the Company shall
not adjust the Conversion Rate for the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of Common Stock or such convertible or exchangeable securities.

 (o) Whenever any provision of this Indenture requires the Company to calculate the Closing Sale Prices over a span of multiple days, an
Independent Committee shall make appropriate adjustments to each account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Record Date of the event occurs, at any
time during the period when the Closing Sale Prices are to be calculated. 
 Section 8.05 Effect of Recapitalizations,
Reclassifications and Changes of the Common Stock. If any of the following events occur, namely: 
 (a) any reclassification of the
Common Stock; 
 (b) any consolidation, merger or binding share exchange involving the Company; or 

(c) any sale, assignment, conveyance, transfer, lease or other disposition to another Person of the Company’s property and assets as an
entirety or substantially as an entirety, 
 in each case, in which the holders of outstanding Common Stock are entitled to receive cash, securities
or other property for their shares of Common Stock (any such event or transaction, a “Reorganization Event”), then, at and after the effective time of such Reorganization Event, the right to convert each $1,000 principal amount of
Debentures shall be changed into a right to convert such principal amount of Debentures into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number
of shares of Common Stock equal to the Conversion Rate immediately prior to such Reorganization Event would have owned or been entitled to receive (the “Reference Property,” with each “unit of Reference Property”
meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive), as determined by an Independent Committee or the governing body of the entity assuming the obligations hereunder, upon completion
of such Reorganization Event; provided, however, in the event the Reorganization Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of
consideration (determined based in part upon any form of stockholder election), the amount and kind of Reference Property into which the Debentures will be convertible shall be deemed to be (i) the weighted average of the types and amounts of
consideration received by the holders of Common Stock that affirmatively make such an election or (ii) if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of
Common Stock. In such event, the Company shall cause notice of the weighted average to be delivered to each Holder, at the address of such Holder as it appears on the Register of the Debentures maintained by the Registrar, as soon as practicable
after such determination has been made.  
 In addition, in the case of such Reorganization Event, the Company or the successor or
purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture providing, without the consent of any Holders, for such change in the right to convert each $1,000 principal amount of Debentures. If, in the case of
any such Reorganization Event, the stock or other securities and assets receivable thereupon by a holder of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as
the case may be, in such Reorganization Event, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders as the Board of Directors shall
reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the conversion rights set forth in this Article 8. 

  
 47 








 If the Debentures become convertible into cash based on the value of the Reference Property, the
Company shall notify the Trustee and issue a press release containing the relevant information (and make such press release available on the Company’s website). 

Throughout this Article 8, if the Common Stock has been replaced by Reference Property as a result of any transaction described in this
Section 8.05, references to Common Stock shall be deemed to refer to such Reference Property. 
 The Company shall cause notice of the
execution of such supplemental indenture to be delivered to each Holder, at the address of such Holder as it appears on the Register of the Debentures maintained by the Registrar, within 20 days after execution thereof. Failure to deliver such
notice shall not affect the legality or validity of such supplemental indenture. 
 The above provisions of this Section 8.05 shall
similarly apply to successive reclassifications, changes, consolidations, mergers, sales, leases, transfers, conveyances or other dispositions. 

The Company may not become party to any such transaction described in clauses (a), (b) or (c) of this Section 8.05, unless the terms
of such transactions are consistent with this Section 8.05. 
 Section 8.06 Responsibility of Trustee. The Trustee and any other
Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine whether or not a convertibility trigger event has occurred, to determine the Conversion Rate or the Conversion Price or whether any facts exist
which may require any adjustment of the Conversion Rate or the Conversion Price, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental
indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any Capital Stock, other
securities or other assets or property, which may at any time be issued or delivered upon the conversion of any Debentures; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any
Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Debentures for the purpose of
conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 8. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any
responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 8.05 hereof relating either to the kind or amount of shares of Capital Stock or other securities or other assets
or property (including cash) receivable by Holders upon the conversion of their Debentures after any event referred to in such Section 8.05 hereof or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01,
may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officer’s Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such
supplemental indenture) with respect thereto. 
 Section 8.07 Notice to Holders Prior to Certain Actions. In the case that: 

(a) the Company shall declare a dividend or any other distribution on its Common Stock that would require an adjustment in the Conversion Rate
pursuant to Section 8.04 hereof; or 
 (b) the Company shall authorize the granting to the holders of all or substantially all of its Common
Stock rights or warrants (other than pursuant to a rights plan) to subscribe for or purchase any share of Common Stock; or 
 (c) of any
reclassification or reorganization of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of
any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or 

  
 48 








 (d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; 

the Company shall cause to be filed with the Trustee and to be delivered to each Holder at its address appearing on the Register provided for in Section 2.14,
as promptly as possible, but in any event at least 20 calendar days prior to the applicable date hereinafter specified to the extent the Company has the knowledge to do so, a notice stating (x) the date on which a record is to be taken for the
purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined, or
(y) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record
shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. Failure to give such notice, or any defect
therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. 

Section 8.08 Stockholder Rights Plans. To the extent the Company has a stockholder rights plan in effect upon conversion of the
Debentures, each share of Common Stock issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any,
in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Debentures, the rights have separated from the shares of Common Stock in
accordance with the provisions of the applicable stockholder rights plan so that the Holders would not be entitled to receive any rights in respect of Common Stock issuable upon conversion of the Debentures, the Conversion Rate shall be adjusted at
the time of separation as if the Company distributed to all, or substantially all, holders of the Common Stock shares of its Capital Stock, evidences of Debt or other assets or property as described in Section 8.04(c) hereof, subject to readjustment
in the event of the expiration, termination or redemption of such rights. 
 Section 8.09 Listing Standards Limitation.
Notwithstanding any provision of this Article 8 to the contrary, the Conversion Rate shall not be increased, and the Company will not enter into any transaction, or take any other voluntary action, that would require an increase of the Conversion
Rate, if such increase in the Conversion Rate would result in a Conversion Price below the market value of the Common Stock as determined in accordance with the listing standards of The NASDAQ Global Select Market without complying, if applicable,
with the stockholder approval rules contained in such listing standards. 
 Article 9 

Repurchase of Debentures at Option of Holders 

Section 9.01 Repurchase at Option of Holders Upon a Fundamental Change 

(a) If there shall occur a Fundamental Change at any time prior to the Maturity Date of the Debentures, then each Holder shall have the right,
at such Holder’s option, to require the Company to repurchase all of such Holder’s Debentures, or any portion thereof that is a multiple of $1,000 of the principal amount, on a date (the “Fundamental Change Repurchase
Date”) specified by the Company, that is not less than 20 calendar days nor more than 35 calendar days after the date of the Company Repurchase Notice related to such Fundamental Change at a cash repurchase price equal to 100% of the
principal amount of the Debentures being repurchased, plus accrued and unpaid interest to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), subject to the satisfaction by the Holder
of the requirements set forth in Section 9.01(c); provided, however, that if such Fundamental Change Repurchase Date falls after the Regular Record Date but on or prior to the corresponding Interest Payment Date, then the interest payable
with respect to such Debentures shall be paid on such Fundamental Change Repurchase Date to the holders of record of the Debentures on the applicable Regular Record Date instead of the Holders surrendering the Debentures for repurchase on such date.

 (b) On or before the fifth calendar day after the occurrence of a Fundamental Change, the Company shall deliver, or cause to be
delivered, notice to all holders of record of the Debentures on the date of such Fundamental Change at their addresses shown in the Register a Company Repurchase Notice as set forth in Section 9.02 with respect to such Fundamental Change. The
Company shall also deliver a copy of the Company Repurchase 

  
 49 








 
Notice to the Trustee and the Paying Agent at such time as it is delivered to Holders. Concurrently with the delivery of such Company Repurchase Notice, the Company shall issue a press release
announcing such Fundamental Change referred to in the Company Repurchase Notice, the form and content of which press release shall be determined by the Company in its sole discretion. 

No failure of the Company to give the foregoing notices and press release and no defect therein shall limit the repurchase rights of Holders
or affect the validity of the proceedings for the repurchase of the Debentures pursuant to this Section 9.01. 
 (c) For Debentures to be
repurchased at the option of the Holder, the Holder must deliver to the Paying Agent, prior to the close of business on the Fundamental Change Repurchase Date, (i) a written notice of repurchase (the “Fundamental Change Repurchase
Notice”) in the form set forth on the reverse of the Debentures duly completed (if the Debentures are certificated) or, a notice of repurchase in accordance with the Applicable Procedures (if the Debentures are represented by a Global
Debenture), stating the following (as applicable): (A) the certificate number of the Debentures which the Holder will deliver to be repurchased (if the Debentures are certificated), (B) the portion of the principal amount of the Debentures

specified in the Debentures and in this Indenture, together with (ii) such Debentures duly endorsed for transfer (if the Debentures are certificated) or book-entry transfer instructions for such Debentures (if such Debentures are represented by
a Global Debenture). The delivery of such Debentures to the Paying Agent with, or at any time after delivery of, the Fundamental Change Repurchase Notice (together with all necessary endorsements, if any) at the office of the Paying Agent shall be a
condition to the receipt by the Holder of the Fundamental Change Repurchase Price therefor; provided, however, that such Fundamental Change Repurchase Price shall be so paid pursuant to this Section 9.01 only if the Debentures so
delivered to the Paying Agent shall conform in all respects to the description thereof in the Fundamental Change Repurchase Notice. All questions as to the validity, eligibility (including time of receipt) and acceptance of any Debentures for
repurchase shall be determined by the Company, whose determination shall be final and binding absent manifest error. 
 (d) The Company
shall repurchase from the Holder thereof, pursuant to this Section 9.01, a portion of a Debenture if the principal amount of such portion is $1,000 or a whole multiple of $1,000. Provisions of this Indenture that apply to the repurchase of all of a
Debenture also apply to the repurchase of such portion of such Debenture. 
 (e) The Paying Agent shall promptly notify the Company of the
receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof. 
 Any repurchase by the Company
contemplated pursuant to the provisions of this Section 9.01 shall be consummated by the delivery of the consideration to be received by the Holder promptly following the later of the Fundamental Change Repurchase Date and the time of the book-entry
transfer or delivery of the Debentures. 
 Section 9.02 Company Repurchase Notice. In connection with any repurchase of
Debentures upon a Fundamental Change, the Company shall, on or before the fifth calendar day after the occurrence of such Fundamental Change, give notice to Holders (with a copy to the Trustee and the Paying Agent) setting forth information
specified in this Section 9.02 (the “Company Repurchase Notice”). 
 Each Company Repurchase Notice shall: 

(i) state the Fundamental Change Repurchase Price and the Fundamental Change Repurchase Date to which the Company Repurchase
Notice relates; 
 (ii) state the event causing the Fundamental Change; 

(iii) state that the Fundamental Change Repurchase Price will be paid in cash; 

  
 50 








 (iv) state that Holders must exercise their right to elect repurchase prior to

(ix) state the then applicable Conversion Rate, including expected changes in the Conversion Rate resulting from such
Fundamental Change pursuant to Section 8.03, if any, and expected changes in the cash, shares or other property deliverable upon conversion of the Debentures as a result of the occurrence of the Fundamental Change pursuant to Section 8.05, if any;

 (x) state that Debentures as to which a Fundamental Change Repurchase Notice has been given may be converted only if the
Fundamental Change Repurchase Notice is withdrawn in accordance with the terms of this Indenture; 
 (xi) state the amount of
interest accrued and unpaid per $1,000 principal amount of Debentures to, but excluding, the Fundamental Change Repurchase Date; and 

(xii) state the CUSIP and ISIN numbers of the Debentures. 

A Company Repurchase Notice may be given by the Company or, at the Company’s request, the Trustee shall give such Company Repurchase Notice in the
Company’s name and at the Company’s expense; provided, however, that the text of the Company Repurchase Notice shall be prepared by the Company. 

The Company will, to the extent applicable, comply with the provisions of Rule 13e-4 and any other tender offer rules under the Exchange Act
that may be applicable at the time of a Company Repurchase Notice, file the related Schedule TO or any other schedule required in connection with any offer by the Company to repurchase the Debentures under the Exchange Act and comply with all other
federal and state securities laws in connection with any offer by the Company to repurchase of the Debentures. 
 Section 9.03

Fundamental Change Repurchase Price shall be paid to such Holder, subject to receipt of funds and/or the Debentures by the Paying Agent, promptly following the later of (x) the Fundamental Change Repurchase Date with respect to such Debentures
(provided the Holder has satisfied the conditions in Section 9.01(c)) and (y) the time of book-entry transfer or delivery of such Debentures to the Paying Agent by the Holder thereof in the manner required by Section 9.01. The Debentures
in respect of which a Fundamental Change Repurchase Notice has been given by the Holder thereof may not be converted pursuant to Article 8 hereof on or after the date of the delivery of such Fundamental Change Repurchase Notice unless such
Fundamental Change Repurchase Notice has first been validly withdrawn. 

  
 51 








 A Fundamental Change Repurchase Notice may be withdrawn by means of a written notice of
withdrawal delivered to the office of the Paying Agent (in the case of certificated Debentures) or by means of a notice of withdrawal in accordance with the Applicable Procedures (in the case of Debentures represented by a Global Debenture) and, in
each case, in accordance with the Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying:

 If on the Fundamental Change Repurchase Date the Paying
Agent holds cash sufficient to pay the Fundamental Change Repurchase Price of the Debentures that Holders have elected to require the Company to repurchase in accordance with Section 9.01, then, on the Fundamental Change Repurchase Date, such
Debentures shall cease to be outstanding, interest shall cease to accrue and all other rights of the Holders of such Debentures shall terminate, other than the right to receive the Fundamental Change Repurchase Price upon delivery or book-entry
transfer of the Debentures. This will be the case whether or not book-entry transfer of the Debentures has been made or the Debentures has been delivered to the Paying Agent. 

Section 9.05 Debentures Repurchased in Part. Upon presentation of any certificated Debentures repurchased only in part, the
Company shall execute and the Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of the Company, a new Debentures or Debentures, of any authorized denomination, in aggregate principal amount equal to the

 56 








 (e) Any meeting duly called pursuant to Section 12.02 at which a quorum is present may be

Section 13.16 Calculations in Respect of Debentures. 

Except as explicitly stated herein, the Company shall be responsible for making all calculations required pursuant to this Indenture,
including, without limitation, calculations with respect to determinations of the average of the Closing Sale Prices of the Common Stock, the accrued interest payable on the Debentures, and the Conversion Rate in effect on the Conversion Date and
the Conversion Price. The Company or its Agents shall make all such calculations in good faith and, absent manifest error, such calculations shall be final and binding on the Holders. The Company shall provide a written schedule of such calculations
to the Trustee and the Conversion Agent, and each of the Trustee and the Conversion Agent shall be entitled to conclusively rely upon the accuracy of the Company’s calculations without responsibility for independent verification thereof. Upon
written direction of the Company, the Trustee shall forward a copy of such calculations to any Holder upon such Holder’s written request. 

Section 13.17 Acts of Holders. 

(a) Any request, demand, authorization, direction, notice, consent, election, waiver or other action provided by this Indenture to be made,
given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing or, alternatively, may be embodied in and evidenced by the
record of Holders voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders duly called and held in accordance with the provisions of Article 12, or a combination of such instruments and any such
record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument
or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the act of the Holders (the “Act of Holders”) signing such instrument or instruments and so voting at any
such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Debenture, shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the
Company, if made in the manner provided in this Section 13.17. The record of any meeting of Holders shall be proved in the manner provided in Section 12.06. 

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof or may be provided in
any other manner which the Trustee and the Company deem sufficient. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority.

 (c) The ownership, principal amount and serial numbers of Debentures held by any Person, and the date of holding the same, shall be
proved by the Register. 
 (d) Any request, demand, authorization, direction, notice, consent, election, waiver or other Act of a Holder
shall bind every future Holder of the same Debenture and the Holder of every Debenture issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the
Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Debenture. 

  
 60 








 (e) Until such time as written instruments shall have been delivered to the Trustee with respect
to the requisite percentage of principal amount of Debentures for the action contemplated by such instruments, any such instrument executed and delivered by or on behalf of a Holder may be revoked with respect to any or all of such Debentures by
written notice by such Holder or any subsequent Holder, proven in the manner in which such instrument was proven. 
 (f) Debentures,
authenticated and delivered after any Act of Holders may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any action taken by such Act of Holders. If the Company shall so determine, new Debentures, so
modified as to conform, in the opinion of the Trustee and the Company, to such action may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for outstanding Debentures. 

(g) The Company may, at its option, by Company Order, fix in advance a record date for the determination of Holders entitled to given any
request, demand, authorization, direction, notice, consent, waiver or other Act of Holders solicited by the Company, but the Company shall have no obligation to do so; provided, however, that the Company may not fix a record date for the
giving or making of any notice, declaration, request or direction referred to in the next sentence. In addition, the Trustee may, at its option, fix in advance a record date for the determination of Holders entitled to join in the giving or making
of any notice of Default, any declaration of acceleration, any request to institute proceedings or any direction, in each case with respect to Debentures. If any such record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act of Holders, or such notice, declaration, request or direction, may be given before or after such record date, but only the Holders of record at the close of business on the record date shall be deemed to be Holders for
the purposes of determining (i) whether Holders of the requisite proportion of the outstanding Debentures have authorized, agreed or consented to such Act of Holders (and for that purpose the outstanding Debentures shall be computed as of the
record date) and (ii) which Holders may revoke any such Act of Holders (notwithstanding subsection (e) of this Section 13.17); and any such Act of Holders, given as aforesaid, shall be effective whether or not the Holders which authorized or
agreed or consented to such Act of Holders remain Holders after such record date and whether or not the Debentures held by such Holders remain outstanding after such record date. 

Section 13.18 U.S.A. PATRIOT Act. 

The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. PATRIOT Act, the Trustee, like all financial
institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each Person that establishes a relationship or opens an account with the Trustee. The
parties to this Indenture agree that they will provide the Trustee with such information as it may request in order for the Trustee to satisfy the requirements of the U.S.A. PATRIOT Act. 

Section 13.19 Force Majeure. 

In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of
or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and
interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to
resume performance as soon as practicable under the circumstances. 

  
 61 








 Section 13.20 Waiver of Jury Trial.  

EACH OF THE COMPANY AND THE TRUSTEE (FOR ITSELF AND ON BEHALF OF HOLDERS) HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE DEBENTURES OR THE TRANSACTIONS CONTEMPLATED HEREBY.

 [FORM OF REVERSE SIDE OF DEBENTURE] 

SUNPOWER CORPORATION 
 4.00%
Senior Convertible Debentures due 2023 
 Interest 

SUNPOWER CORPORATION, a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to,
being herein called the “Company”), promises to pay interest on the principal amount of this Debenture at the rate per annum shown above. The Company will pay interest semi-annually on January 15 and July 15 of each year,
commencing on July 15, 2016. Interest on the Debentures will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the Issue Date. Interest will be computed on the basis of a 360-day year of
twelve 30-day months, and, for partial months, on the basis of the number of days actually elapsed in a 30-day month. If any payment date (including any repurchase date upon a Fundamental Change) is not a Business Day, payment will be made on the
next succeeding Business Day, and no Additional Interest will accrue in respect of such payment by virtue of the payment being made on such later date. 

Method of Payment 
 The Company
will pay interest on the Debentures (except defaulted interest) to the Persons who are registered Holders at the close of business on the January 1 and July 1 immediately preceding the Interest Payment Date even if Debentures are canceled
after the record date and on or before the Interest Payment Date, except as otherwise provided in the Indenture. Holders must surrender Debentures to a Paying Agent to collect principal payments. The Company will pay principal and interest in money
of the United States of America that at the time of payment is legal tender for payment of public and private debts. The Company shall pay interest (i) on any Global Debentures by wire transfer in immediately available funds to the account of
the Depositary or its nominee, (ii) on any Debentures in certificated form having a principal amount of less than $2,000,000, by check mailed to the address of the Person entitled thereto as it appears in the Register, provided, however,
that at maturity interest will be payable at the office of the Company maintained by the Company for such purposes, which shall initially be an office or agency of the Trustee (as defined below) and (iii) on any Debentures in certificated form
having a principal amount of $2,000,000 or more, by wire transfer in immediately available funds at the election of the Holder of such Debentures duly delivered to the Trustee at least five Business Days prior to the relevant Interest Payment Date
or by check if no such election is made, provided, however, that, at maturity, interest will be payable at the office of the Company maintained by the Company for such purposes, which shall initially be an office or agency of the Trustee. 

 If the Company defaults on a payment of the Redemption Price, the Fundamental Change Repurchase Price, principal or interest on the
Debentures, such Defaulted Amounts shall accrue at the then applicable interest rate on the Debentures from the required payment date (to the extent lawful). The Company may pay Defaulted Amounts together with such interest thereon to the Persons
who are Holders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee and shall promptly deliver or cause to be delivered to each
Holder a notice that states the special record date, the payment date and the amount of Defaulted Amounts to be paid. 
 Paying Agent, Registrar, Service
Agent and Conversion Agent 
 Initially, Wells Fargo Bank, National Association, a national banking association (the
“Trustee”), will act as Paying Agent, Registrar and Conversion Agent. The Company may appoint and change any Paying Agent, Registrar or co-registrar, service agent or Conversion Agent without notice. The Company or any of its domestically
organized Subsidiaries may act as Paying Agent, Registrar or co-registrar, service agent or Conversion Agent. 

  
 A-6 








 Indenture 

The Company issued the Debentures under an indenture dated as of December 15, 2015 (the “Indenture”), between the Company and
the Trustee. The terms of the Debentures include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 as in effect on the date of the Indenture (the “TIA”). Terms defined
in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Debentures are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of those terms. 

The Debentures are senior unsecured obligations of the Company. This Debenture is one of the Debentures referred to in the Indenture. The
aggregate principal amount of Debentures that may be authenticated and delivered pursuant to the Indenture is initially limited to $400,000,000 (as increased by an amount equal to the aggregate principal amount of any additional Debentures purchased
by the Initial Purchasers pursuant to the exercise of their option to purchase additional Debentures as set forth in the Purchase Agreement). The Indenture imposes limitations on the ability of the Company to consolidate or merge with or into any
other Person or convey, transfer or lease the property of the Company substantially as an entirety. 
 Optional Redemption 

Prior to a Fundamental Change Repurchase Date relating to a Non-Stock Change of Control Fundamental Change, the Debentures shall not be
redeemable at the option of the Company. For a period of 30 calendar days following a Fundamental Change Repurchase Date relating to a Non-Stock Change of Control, the Company may redeem the outstanding Debentures not converted or repurchased by the
Company, in whole but not in part, at the Company’s option. In the case of any Optional Redemption, the Company will provide not less than 10 nor more than 30 calendar days’ notice before the Redemption Date to the Trustee, the Paying
Agent and each Holder, and the cash Redemption Price will be equal to 100% of the principal amount of the Debentures to be redeemed, plus accrued and unpaid interest to, but excluding, the Redemption Date (unless the Redemption Date falls after a
Regular Record Date but on or prior to the immediately succeeding Interest Payment Date, in which case we will pay the full amount of accrued and unpaid interest to the Holder of the close of business on such Regular Record Date, and the Redemption
Price will be equal to 100% of the principal amount of the Debentures to be redeemed). The Redemption Date must be a Business Day. 
 No
Debentures may be redeemed if the principal amount of the Debentures has been accelerated, and such acceleration has not been rescinded, on or prior to the Redemption Date (except in the case of an acceleration resulting from a Default by the
Company us in the payment of the Redemption Price with respect to such Debentures). 
 If cash sufficient to pay the Redemption Price of all
Debentures to be redeemed as of the Redemption Date is deposited with the Paying Agent on the Redemption Date, then such Debentures will cease to be outstanding and interest will cease to accrue, and the Holder thereof shall have no other rights as
such other than the right to receive the Redemption Price upon delivery or book-entry transfer of such Debentures. 
 Except as set forth
above, the Debentures may not be redeemed at the Company’s option prior to the Maturity Date. 
 Sinking Fund 

The Debentures are not subject to any sinking fund. 

  
 A-7 








 Repurchase at Option of Holders Upon a Fundamental Change 

If a Fundamental Change occurs at any time prior to maturity of the Debentures, this Debenture will be subject to a repurchase, at the option
of the Holder, on the Fundamental Change Repurchase Date specified by the Company, that is not less than 20 calendar days nor more than 35 calendar days after notice thereof, at a cash Fundamental Change Repurchase Price equal to 100% of the
principal amount hereof, together with accrued and unpaid interest on this Debenture to, but excluding, the Fundamental Change Repurchase Date; provided, however, that if such Fundamental Change Repurchase Date falls after a Regular Record
Date and on or prior the corresponding Interest Payment Date, the interest payable on such Interest Payment Date will be paid on such Interest Payment Date to the Holder of this Debenture as of the close of business on such Regular Record Date
instead of the Holders surrendering Debentures for repurchase on such date. The Debentures submitted for repurchase must be $1,000 in principal amount or whole multiples thereof. The Company shall deliver to all Holders of record of the Debentures a
notice of the occurrence of a Fundamental Change and of the repurchase right arising as a result thereof on or before the fifth calendar day after the occurrence of such Fundamental Change. For Debentures to be so repurchased at the option of the
Holder, the Holder must deliver to the Paying Agent in accordance with the terms of the Indenture, the Fundamental Change Repurchase Notice containing the information specified by the Indenture, together with such Debentures, duly endorsed for
transfer, or (if the Debentures are Global Debentures) book-entry transfer of the Debentures, prior to the close of business on the Fundamental Change Repurchase Date. The Fundamental Change Repurchase Price must be paid in cash. 

Holders have the right to withdraw any Fundamental Change Repurchase Notice by delivering to the Paying Agent a written notice of withdrawal
at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, as provided in the Indenture. 

If cash sufficient to pay the Fundamental Change Repurchase Price of all Debentures or portions thereof to be repurchased as of the
Fundamental Change Repurchase Date is deposited with the Paying Agent on the Fundamental Change Repurchase Date, then such Debentures will cease to be outstanding and interest will cease to accrue, and the Holder thereof shall have no other rights
as such other than the right to receive the Fundamental Change Repurchase Price upon delivery or book-entry transfer of such Debentures. 
 Conversion

 In compliance with the provisions of the Indenture, the Holder hereof has the right, at its option, to convert each $1,000 principal
amount of this Debenture into shares of Common Stock at any time prior to the close of business on the Business Day preceding the Maturity Date based on a Conversion Rate of 32.7568 shares of Common Stock per $1,000 principal amount of Debentures,
subject to adjustment pursuant to the terms of the Indenture, as such shares shall be constituted at the Conversion Date, upon surrender of this Debenture (if in certificated form) with the form entitled “Form of Conversion Notice” on the
reverse hereof duly completed and manually signed, to the Company at the office or agency of the Company maintained for that purpose in accordance with the terms of the Indenture, or at the option of such Holder, the Corporate Trust Office, together
with any funds required pursuant to the terms of the Indenture, and duly endorsed by, or accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder or by such Holder’s duly authorized attorney. In
order to exercise the conversion right with respect to any interest in a Global Debenture, the Holder must comply with the Depositary’s procedures for converting a beneficial interest in a Global Debenture, deliver by book-entry delivery an
interest in such Global Debenture, furnish appropriate endorsements and transfer documents if required by the Company or the Trustee or Conversion Agent, and pay the funds, if any, required pursuant to the terms of the Indenture. 

Prior to the Maturity Date, if and only to the extent Holders elect to convert the Debentures in connection with a Non-Stock Change of Control
Fundamental Change, the Company will increase the Conversion Rate applicable to such converting Debentures as set forth in the Indenture. 

No adjustment in respect of interest on any Debentures converted will be made upon any conversion except as set forth in the next sentence. If
this Debenture (or portion hereof) is surrendered for conversion during the period from the close of business on any applicable Regular Record Date for the payment of interest to the close of business on the Business Day preceding the corresponding
Interest Payment Date, this Debenture (or portion hereof being converted) must be accompanied by payment, in immediately available funds or 

  
 A-8 








 
other funds acceptable to the Company, of an amount equal to the interest that has accrued and would be paid on such Interest Payment Date on the principal amount being converted;
provided, that no such payment shall be required (1) if the Holder surrenders this Debenture for conversion following the Regular Record Date immediately preceding the Maturity Date, (2) if the Company has specified a Fundamental
Change Repurchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, or, if later, the Business Day on which such interest is payable pursuant to the Indenture, (3) if the Company has specified
a Redemption Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date or (4) to the extent of any overdue interest, if overdue interest exists at the time of conversion with respect to this Debenture.

 A Debenture in respect of which a Holder is exercising its right to require repurchase may be converted only if such Holder validly
withdraws its election to exercise such right to require repurchase in accordance with the terms of the Indenture. 
 Denominations, Transfer, Exchange

 The Debentures are in registered form without coupons in denominations of $1,000 and whole multiples of $1,000. A Holder may transfer
or exchange Debentures in accordance with the Indenture. Upon any transfer or exchange, the Registrar or the Company may require a Holder, among other things, to furnish appropriate endorsements or a written instrument or instruments of transfer in
form satisfactory to the Company and the Trustee. Neither the Company, the Trustee nor the Registrar shall be required to exchange, issue or register a transfer of (a) any Debentures or portions thereof surrendered for conversion pursuant to
Article 8 of the Indenture and (b) any Debentures or portions thereof tendered for repurchase (and not withdrawn) pursuant to Section 9.01 of the Indenture. 

Persons Deemed Owners 
 The registered
Holder of this Debenture may be treated as the owner of it for all purposes. 
 Unclaimed Money 

Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon written request any money held
by them for the payment of principal or interest and any shares of Common Stock or other property due in respect of converted Debentures that remains unclaimed for two years, and, thereafter, Holders entitled to the money and/or securities must look
to the Company for payment as general creditors. 
 Amendment, Waiver 

Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Debentures may be amended with the written consent of
the Holders of at least a majority in aggregate principal amount of the outstanding Debentures and (ii) any Default or noncompliance with any provision may be waived with the written consent or affirmative vote of the Holders of at least a
majority in principal amount of the outstanding Debentures. Without the consent of any Holder, the Company and the Trustee may amend the Indenture or the Debentures (i) to provide for conversion rights of Holders and the Company’s
repurchase obligations in connection with a Fundamental Change in the event of any reclassification of the Common Stock, merger or consolidation, or sale, conveyance, transfer or lease of the Company’s property and assets substantially as an
entirety; (ii) to secure the Debentures; (iii) to provide for the assumption of the Company’s obligations to the Holders of the Debentures in the event of a merger or consolidation, or sale, conveyance, transfer or lease of the
Company’s property or assets substantially as an entirety; (iv) to surrender any right or power conferred upon the Company in the Indenture; (v) to add to the covenants of the Company for the benefit of the Holders; (vi) to cure
any ambiguity or correct or supplement any inconsistent or otherwise defective provision contained in the Indenture, provided, however, that 

  
 A-9 








 
such modification or amendment does not adversely affect the interests of the Holders in any material respect, provided, further, that any amendment made solely to conform the
provisions of the Indenture or the Debentures to the description of the Debentures contained in the Offering Memorandum shall not be deemed to adversely affect the interests of the Holders; (vii) to make any provision with respect to matters or
questions arising under the Indenture or the Debentures that the Company may deem necessary or desirable and that shall not be inconsistent with the provisions of the Indenture or the Debentures; provided, that such change or modification
does not, in the good faith opinion of an Independent Committee, adversely affect the interests of the Holders in any material respect; (viii) to increase the Conversion Rate; (ix) to comply with requirements of the SEC in order to effect
or maintain the qualification of the Indenture under the TIA; (x) to add guarantees of the obligations under the Debentures; and (xi) to provide for a successor Trustee. 

Defaults and Remedies 
 If an Event of
Default occurs (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company) and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then-outstanding
Debentures, by written notice to the Company and the Trustee, may declare due and payable 100% of the principal amount of all outstanding Debentures plus any accrued and unpaid interest to the date of payment. If an Event of Default relating to
certain events of bankruptcy, insolvency or reorganization of the Company occurs, all unpaid principal and accrued and unpaid interest on the outstanding Debentures shall become due and immediately payable without any declaration or other act on the
part of the Trustee or any Holder. Under certain circumstances, the Holders of a majority in aggregate principal amount of the outstanding Debentures may rescind and annul any such acceleration with respect to the Debentures and its consequences.

 If an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under
the Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability or expense. Subject to certain exceptions, no
Holder may pursue any remedy with respect to the Indenture or the Debentures unless (i) such Holder has previously given the Trustee notice that an Event of Default is continuing, (ii) Holders of at least 25% in principal amount of the
outstanding Debentures have requested the Trustee in writing to pursue the remedy, (iii) such Holders have offered the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability or expense, (iv) the
Trustee has not complied with such request within 60 days after the receipt of the request and the offer of indemnity and (v) the Holders of a majority in principal amount of the outstanding Debentures have not given the Trustee a direction
inconsistent with such request within such 60-day period. Subject to certain restrictions, the Holders of a majority in principal amount of the outstanding Debentures are given the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. Subject to the Indenture, the Trustee, however, may refuse to follow any direction if the Trustee, in good faith shall, by a Trust
Officer of the Trustee, determine that the proceeding so directed would involve the Trustee in personal liability. The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by the Indenture at the request, order
or direction of any Holder pursuant to the provision of the Indenture, unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities which may be
incurred therein or thereby. 
 No reference herein to the Indenture and no provision of this Debenture or of the Indenture shall impair, as
among the Company and the Holder, the obligation of the Company, which is absolute and unconditional, to pay the principal and interest in respect of the Debenture at the place, at the respective times, at the rate and in the coin or currency herein
and in the Indenture prescribed. 
 Trustee Dealings with the Company 

Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the
owner or pledgee of Debentures and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 

  
 A-10 








 No Recourse Against Others 

A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the
Debentures or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Debenture waives and releases all such liability. The waiver and release are part of the
consideration for the issue of the Debentures. 
 Authentication 

This Debenture shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Debenture. 
 Abbreviations 

Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act). 

GOVERNING LAW 
 THIS DEBENTURE SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, INCLUDING, WITHOUT LIMITATION, SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW. 

CUSIP and ISIN Numbers 
 Pursuant to a
recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP and ISIN numbers to be printed on the Debentures and has directed the Trustee to use CUSIP and ISIN numbers in notices of
redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Debentures or as contained in any notice of redemption and reliance may be placed only on the other identification numbers
placed thereon. 
 The Company will furnish to any Holder upon written request and without charge to the Holder a copy of the Indenture
which has in it the text of this Debenture.
