 Exhibit 10.15 
  
 2005 Annual Incentive Program 
  
 Under the Owens & Minor, Inc. 1998 Stock Option and Incentive Plan, the Compensation & Benefits Committee
(“Compensation Committee”) of the Board of Directors is responsible for designating participants to whom incentive awards are made for annual incentive payments and for determining the goals and objectives on which such incentive awards
are based. 
  
 The Compensation Committee has approved the 2005
Incentive Program which designates teammates of the Company eligible to participate in the program and specifies the terms and conditions of incentive awards that may be granted to such teammates under the 1998 Stock Option and Incentive Plan, based
upon the achievement of certain financial and operational results during calendar year 2005. Under the 2005 Incentive Program, all corporate officers, operating company officers and teammates having a title of “manager” and pay grade of 14
or above (excluding “project managers”) are eligible to participate in the program, provided the teammate is an active employee on December 31, 2005 and the date the award is granted. 
  
 The target cash and restricted stock awards as a percentage of base salary
for each corporate officer level are stated below:

	 VP
	  	28%	  	+	  	7%	  	=	  	35%

  
 The financial and
operational objectives for the 2005 Annual Incentive Program are based on the Company’s net sales, net income (or in certain instances, net income of the Company’s OMSolutions operating unit), SG&A expense and gross margin. Incentive
awards will be granted shortly after the end of the 2005 calendar year if performance criteria are met.Form of Indenture

 Where any Person is required to make, give or execute two or more applications, requests, consents,
certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument. 
  
 Section 1.4 Acts of Holders; Record Dates. 
  
 Any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken
by Holders shall be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by their respective agent or agents duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. The Trustee shall promptly deliver to the Company copies of all such instrument
or instruments delivered to the Trustee. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 6.1) conclusive in favor of the Trustee and the Company, if made in the manner provided in this
Section. 
  
 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 or her the execution thereof. Where such execution is by a signer acting in a capacity other than his or her individual capacity, such certificate or affidavit shall also constitute sufficient proof of his
or her authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient. 
  
 The ownership of Securities shall be proved by the Security Register.

  
 Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security 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 Security. 
  
 The Company may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any
series entitled to give, make or take any request, demand, authorization, direction, vote, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such series, provided
that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any 

  

 9 

 
record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall
be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the
requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been
set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by
Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of
such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 1.6. 
  
 The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 5.2, (iii) any request to institute proceedings referred to in
Section 5.7(2), (iv) any direction referred to in Section 5.12 or (v) any other purpose required under this Indenture, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of
Outstanding Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to
prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled
and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after
any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to
each Holder of Securities of the relevant series in the manner set forth in Section 1.6. 
  
 With respect to any record date set pursuant to this Section, the party hereto which sets such record date may designate any day as the “Expiration Date” and from time to time may change the Expiration Date
to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series in the manner set
forth in Section 1.6, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to 

  

 10 

 
this Section, the party hereto which set such record date shall be deemed to have initially designated the 180th day after such record date as the Expiration
Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date. 
  
 Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all
or any part of such principal amount. 
  
 Section 1.5 Notices, Etc., to Trustee
and Company. 
  
 Any request, demand, authorization,
direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, 
  
 (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made,
given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Department, and shall be deemed given when mailed by first class mail, postage prepaid, or by any reputable same or next day
delivery service, or transmitted by any telegraphic, facsimile or similar service, provided that oral confirmation of receipt shall have been received or 
  
 (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if made, given, furnished or filed in writing to or with the Company at its principal office specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company,
Attention: Chief Financial Officer, and shall be deemed given when mailed by first class mail, postage prepaid, or by any reputable same or next day delivery service, or transmitted by any telegraphic, facsimile or similar service, provided that
oral confirmation of receipt shall have been received. 
  
 Section 1.6 Notice
to Holders; Waiver. 
  
 Where this Indenture or the Trust
Indenture Act provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, or delivered by hand or overnight courier to each
Holder, as of the applicable record date, affected by such event, at its address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such
notice. Neither the failure to mail or deliver by hand or overnight courier any such notice, nor any defect in any such notice so mailed or delivered by hand or overnight courier, to any particular Holder shall affect the sufficiency of such notice
with respect to other 

  

 11 

 
Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon
such waiver. 
  
 In case by reason of the suspension of regular
mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

  
 Section 1.7 Conflict with Trust Indenture Act. 
  
 If any provision hereof limits, qualifies or conflicts with a provision of
the Trust Indenture Act which is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act which may be so
modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

 Nothing in this Indenture or in the Securities, express or implied, shall
give to any Person, other than the parties hereto and their successors hereunder and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture.

 In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security or the last date on which a
Holder has the right to convert a Security at a particular conversion price shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities (other than a provision of any Security
which specifically states that such provision shall apply in lieu of this Section)) payment of interest or principal (and premium, if any) or, if applicable to a particular series of Securities, conversion need not be made at such Place of Payment
on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, at the Stated Maturity or on such last day for conversion, as the
case may be.

any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of this Indenture and the issue of the Securities.

 (13) if other than the entire principal amount thereof, the portion of the principal amount of any Securities of the series which shall be
payable upon declaration of acceleration of the Maturity thereof pursuant to Section 5.2;

dates prior to the Stated Maturity, the amount which shall be deemed to be the principal amount of such Securities as of any such date for any purpose thereunder or hereunder, including the principal amount thereof which shall be due and payable
upon any Maturity other than the Stated Maturity or which shall be deemed to be Outstanding as of any date prior to the Stated Maturity (or, in any such case, the manner in which such amount deemed to be the principal amount shall be determined);

  
 (15) if applicable, that the Securities of
the series, in whole or any specified part, shall be defeasible pursuant to Section 13.2 or Section 13.3 or both such Sections and, if other than by a Board Resolution, the manner in which any election by the Company to defease such Securities shall

 (16) if applicable, the terms of any right to convert Securities of the series into
shares of Common Stock of the Company or other securities or property; 
  
 (17) if applicable, that any Securities of the series shall be issuable in whole or in part in the form of one or more Global Securities and, in such case, the respective Depositaries for such Global Securities, the
form of any legend or legends which shall be borne by any such Global Security in addition to or in lieu of that set forth in Section 2.2 and any circumstances in addition to or in lieu of those set forth in Clause (2) of the last paragraph of
Section 3.5 in which any such Global Security may be exchanged in whole or in part for Securities registered, and any transfer of such Global Security in whole or in part may be registered, in the name or names of Persons other than the Depositary
for such Global Security or a nominee thereof; 
  
 (18) any addition to or change in the Events of Default which applies to any Securities of the series and any change in the right of the Trustee or the requisite Holders of such Securities to declare the principal amount thereof due and

 Securities of any one series shall be
substantially identical except as to denomination and except as may otherwise be provided in or pursuant to the Board Resolution referred to above, (subject to Section 3.3) set forth, or determined in the manner provided, in the Officers’
Certificate referred to above or in any such indenture supplemental hereto. 
  
 If any of the terms of the series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the
Company and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth the terms of the series. 
  
 Section 3.2 Denominations. 
  
 The Securities of each series shall be issuable only in registered form without coupons and only in such denominations as shall be specified as
contemplated by Section 3.1. In the absence of any such specified denomination with respect to the Securities of any series, the Securities of such series shall be issuable in denominations of $1,000 and any integral multiple thereof. 
  

 18 

 Section 3.3 Execution, Authentication, Delivery and Dating. 
  
 The Securities shall be executed on behalf of the Company by its Chairman of
the Board, its Vice Chairman of the Board, its Chief Executive Officer, its principal financial officer, its President or one of its Vice Presidents, and attested by its Treasurer, Secretary or one of its Assistant Treasurers, Assistant Secretaries,
or Vice Presidents (other than any Vice President whose execution of the Securities is being attested to). The signature of any of these officers on the Securities may be manual or facsimile. 
  
 Securities bearing the manual or facsimile signatures of individuals who were
at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at
the date of such Securities. 
  
 At any time and from time to time
after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and
the Trustee in accordance with the Company Order shall authenticate and deliver such Securities. If the form or terms of the Securities of the series have been established by or pursuant to one or more Board Resolutions as permitted by Sections 2.1
and 3.1, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 6.1) shall be fully protected in relying
upon, a copy of such Board Resolution, Officers’ Certificate, or supplemental indenture setting forth the terms of the Securities of the series and an Opinion of Counsel, with such Opinion of Counsel stating, 
  
 (1) if the form of such Securities has been established by
or pursuant to Board Resolution, Officers’ Certificate, or supplemental indenture as permitted by Section 2.1, that such form has been established in conformity with the provisions of this Indenture; 
  
 (2) if the terms of such Securities have been established by
or pursuant to Board Resolution, Officers’ Certificate, or supplemental indenture as permitted by Section 3.1, that such terms have been established in conformity with the provisions of this Indenture; 
  
 (3) that such Securities, when authenticated and delivered
by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company enforceable in accordance with their terms, subject to
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles; and 
  

 19 

 (4) if all Securities of a series are not to be originally issued at one time, and the
Board Resolution, Officer’s Certificate, or supplemental indenture pursuant to which such Securities are issued does not require an Officer’s Certificate otherwise required pursuant to Section 3.1 or the Company Order and Opinion of
Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each subsequent Security of such series, that it will not be necessary for the Company to deliver or cause to be delivered an Officer’s
Certificate otherwise required pursuant to Section 3.1 or a Company Order or an Opinion of Counsel otherwise required pursuant to Section 3.1 at or prior to the authentication of subsequently-issued Securities of such series. 
  
 If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not
reasonably acceptable to the Trustee. 
  
 Notwithstanding the
provisions of Section 3.1 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 3.1 or
the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original
issuance of the first Security of such series to be issued and the Company Order so provides. 
  
 Each Security shall be dated the date of its authentication. 
  
 No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for
herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if
any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.9, for all purposes of this Indenture
such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. 
  
 Neither the Company nor the Trustee shall have any responsibility for any defect in the CUSIP number that appears on any Security, check, advice of
payment or redemption notice, and any such document may contain a statement to the effect that CUSIP numbers have been assigned by an independent service for convenience of reference and that neither the Company nor the Trustee shall be liable for
any inaccuracy in such numbers. 
  

 20 

 Section 3.4 Temporary Securities. 
  
 Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee
shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. 
  
 If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series
upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any
series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount. Until so
exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series and tenor. 
  
 Section 3.5 Registration; Registration of Transfer and Exchange. 
  
 The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such
office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company
shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided. 
  
 Upon surrender for registration of transfer of any Security of a series at
the office or agency of the Company in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same
series, of any authorized denominations and of like tenor and aggregate principal amount. 
  
 At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the
Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled
to receive. 
  

 21 

 All Securities issued upon any registration of transfer or exchange of Securities shall be the valid
obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. 
  
 Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or
the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. 
  
 No service charge shall be made for any registration of transfer or exchange
of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to
Section 3.4, 9.6 or 11.7 not involving any transfer. 
  
 If the
Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as
the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of any such Securities selected for redemption under Section 11.3 and ending at the close of business on the day of
such mailing, or (B) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 
  
 The provisions of Clauses (1), (2), (3) and (4) below shall apply only to
Global Securities: 
  
 (1) Each Global Security
authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security
shall constitute a single Security for all purposes of this Indenture. 
  
 (2) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole or in part for Securities registered, and no transfer of a Global Security in whole or in part may be registered,
in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (A) such Depositary (i) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or (ii) has
ceased to be a clearing agency registered under the Exchange Act, (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security or (C) there shall exist such circumstances, if any, in addition to or in lieu
of the foregoing as have been specified for this purpose as contemplated by Section 3.1. 
  

 22 

 (3) Subject to Clause (2) above, any exchange provided for herein or pursuant hereto of a
Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct.

  
 (4) Every Security authenticated and
delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Section 3.4, 3.6, 9.6 or 11.7 or otherwise, shall be authenticated and delivered in the form
of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof. 
  
 Section 3.6 Mutilated, Destroyed, Lost and Stolen Securities. 
  
 If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
  
 If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and proof
of ownership of that Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been
acquired by a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing
a number not contemporaneously outstanding. 
  
 In case any such
mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. 
  
 Upon the issuance of any new Security under this Section, the Company and the Trustee may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee and the Company and their agents and counsel) connected therewith. 
  
 Every new Security of any series issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the
benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. 
  

 23 

 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights
and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
  
 Section 3.7 Payment of Interest; Interest Rights Preserved. 
  
 Except as otherwise provided as contemplated by Section 3.1 with respect to any series of Securities, interest on any Security which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

  
 Any interest on any Security of any series which is payable,
but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder,
and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Clause (1) or (2) below: 
  
 (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their
respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to
such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed
payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause
notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in Section 1.6, not less than 10 days prior to such Special Record Date.
Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor
Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2). 
  

 24 

 (2) The Company may make payment of any Defaulted Interest on the Securities of any
series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the
Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by and acceptable to the Trustee. 
  
 Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or
in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 
  
 Subject to the provisions of Section 14.2, in the case of any Security (or any part thereof) which is converted after any Regular Record Date and on or
prior to the next succeeding Interest Payment Date (other than any Security the principal of (or premium, if any, on) which shall become due and payable, whether at Stated Maturity or by declaration of acceleration prior to such Interest Payment
Date), interest whose Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such conversion and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person
in whose name that Security (or any one or more Predecessor Securities) is registered at the close of business on such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence or in Section 14.2, in the case
of any Security (or any part thereof) which is converted, interest whose Stated Maturity is after the date of conversion of such Security (or such part thereof) shall not be payable. 
  
 Section 3.8 Persons Deemed Owners. 
  
 Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 3.7) any interest on such Security and for all other purposes whatsoever,
whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 
  
 Section 3.9 Cancellation. 
  
 All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and
sold, and all Securities 

  

 25 

 
so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as
provided in this Section, except as expressly permitted by this Indenture. All canceled Securities held by the Trustee shall be disposed of as directed by a Company Order, or if no such directions are set forth therein, as the Trustee determines in
its discretion. 
  
 Section 3.10 Computation of Interest. 
  
 Except as otherwise specified as contemplated by Section 3.1 for Securities
of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. 
  
 ARTICLE IV 
 SATISFACTION AND
DISCHARGE 
  
 Section 4.1 Satisfaction and Discharge of Indenture.

  
 This Indenture shall upon Company Request cease to be of
further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly provided for), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when 
  
 (1) either

  
 (A) all Securities theretofore authenticated
and delivered (other than (i) Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 3.6 and (ii) Securities for whose payment money has theretofore been deposited in trust or segregated and
held in trust by the Trustee or the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 10.3) have been delivered to the Trustee for cancellation; or 
  
 (B) all such Securities not theretofore delivered to the
Trustee for cancellation 
  
 (i) have become due
and payable, or 
  
 (ii) will become due and
payable at their Stated Maturity within one year, or 
  
 (iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, 
  
 and the Company, in the case of (i), (ii) or (iii) above, has deposited or
caused to be deposited with the Trustee as trust funds in trust for this purpose money in an amount sufficient to pay and discharge the entire indebtedness on such 

  

 26 

 
Securities not theretofore delivered to the Trustee for cancellation, for principal and any premium and interest to the date of such deposit (in the case of
Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; 
  
 (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and 
  
 (3) the Company has delivered to the Trustee an
Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. 
  
 Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.7, the obligations of the Trustee to any Authenticating Agent under Section 6.14 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of this
Section, the obligations of the Trustee under Section 4.2 and the last paragraph of Section 10.3 shall survive. 
  
 In addition to the forgoing, those provisions relating to the maturity of Securities, interest payments and dates thereof, the tender of Securities for
purchase and the Trustee’s remedies with respect thereto, the exchange, transfer and registration of Securities, the replacement and cancellation of Securities, the holding of moneys in trust and the duties of the Trustee in connection with all
of the foregoing shall remain in full force and effect and shall be binding upon the Trustee, the Holders of the Securities and the Company notwithstanding the release and discharge of this Indenture until the Securities have been actually paid in
full. 
  
 Section 4.2 Application of Trust Money. 
  
 Subject to the provisions of the last paragraph of Section 10.3, all money
deposited with the Trustee pursuant to Section 4.1 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto under the terms of this Indenture, of the principal and any premium and interest for whose payment such money has been deposited with the Trustee.

  
 ARTICLE V

 “Event of Default,” wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be

 (4) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty
a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture solely for the benefit of series of Securities other than that series), and continuance of
such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding
Securities of that series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or

 (7) any other Event of Default provided with respect to Securities of that series. 
  
 Section 5.2 Acceleration of Maturity; Rescission and Annulment. 
  
 If an Event of Default (other than an Event of Default specified in Section
5.1(5) or 5.1(6)) with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee if indemnified as provided in Section 6.3(5), or the Holders of not less than 25% in principal amount of
the Outstanding Securities of that series, may declare the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as
may be specified by the terms thereof) to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become
immediately due and payable. If an Event of Default specified in Section 5.1(5) or 5.1(6) with respect to Securities of any series at the time Outstanding occurs, the principal amount of all the Securities of that series (or, if any Securities of
that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) shall automatically, and without any declaration or other action on the part of the Trustee or any
Holder, become immediately due and payable. 
  
 At any time after
such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a
majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if 
  
 (1) the Company has paid or deposited with the Trustee a sum
sufficient to pay 
  
 (A) all overdue interest on
all Securities of that series, 
  
 (B) the
principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities, 
  
 (C) to the extent that payment of such interest is lawful,
interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and 
  

 29 

 (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel; and 
  
 (2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that
series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13. No such rescission shall affect any subsequent default or impair any right consequent thereon. 
  
 Section 5.3 Collection of Indebtedness and Suits For Enforcement by Trustee.

  
 The Company covenants that if 
  
 (1) default is made in the payment of any interest on any
Security when such interest becomes due and payable and such default continues for a period of 30 days, or 
  
 (2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof, 
  
 the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of
such Securities, the whole amount then due and payable on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on
any overdue interest, at the rate or rates prescribed therefor in such Securities, 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 an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series 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 5.4 Trustee May File
Proofs of Claim. 
  
 In case of any judicial proceeding
relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust
Indenture Act, this Indenture or otherwise at law or in equity in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property
payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in 

  

 30 

 
any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 6.7. 
  
 No provision of this Indenture shall be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee
to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or
other similar committee. 
  
 Section 5.5 Trustee May Enforce Claims Without
Possession of Securities. 
  
 All rights of action and claims
under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities 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 of the Securities in respect of which such judgment has been recovered. 
  
 Section 5.6 Application of Money Collected. 
  
 Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or
any premium or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 
  
 FIRST: To the payment of all amounts due the Trustee under Section 6.7; 
  
 SECOND: To the payment of the amounts then due and unpaid for principal of
and any premium, if any, and interest on the Securities 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 Securities
for principal and any premium, if any, and interest, respectively; and 
  
 THIRD: The balance, if any, to the Company or any other Person or Persons entitled thereto. 
  

 31 

 Section 5.7 Limitation on Suits. 
  
 No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with
respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless 
  
 (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that
series; 
  
 (2) the Holders of not less than 25%
in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
  
 (3) such Holder or Holders have offered to the Trustee
reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; 
  
 (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding;
and 
  
 (5) no direction inconsistent with such
written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series; it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of
such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders. 
  
 Section 5.8 Unconditional Right of Holders to Receive Principal, Premium and Interest and To Convert. 
  
 Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 3.7) interest on such Security on the respective Stated Maturities expressed in such Security (or, in
the case of redemption, on the Redemption Date), to convert such Securities in accordance with Article XIV to the extent that such right to convert is applicable to such Security and to institute suit for the enforcement of any such payment, and
such rights shall not be impaired without the consent of such Holder. 
  
 Section 5.9 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 

  

 32 

 
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 5.10 Rights and Remedies Cumulative. 
  
 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities
in the last paragraph of Section 3.6, 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
5.11 Delay or Omission Not Waiver. 
  
 No delay or omission
of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right
and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee (subject to the limitations contained in this Indenture) or by the Holders, as
the case may be. 
  
 Section 5.12 Control By Holders. 
  
 The Holders of a majority in principal amount of the Outstanding Securities
of any series 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 Securities of such series,
provided that 
  
 (1) such direction shall not be
in conflict with any rule of law or with this Indenture and the Trustee shall not have determined that the action so directed would be unjustly prejudicial to Holders of Securities of that series, or any other series, not taking part in such
direction and indemnification is provided to the Trustee under Section 6.3(5); and 
  
 (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction or this Indenture.

  
 Section 5.13 Waiver of Past Defaults. 
  
 The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to such series and its consequences, except 
  

 33 

 (1) a default in the payment of the principal of or any premium or interest on any
Security of such series; or 
  
 (2) to the extent
such right is applicable to such Security, a failure by the Company on request to convert any Security into Common Stock; or 
  
 (3) in respect of a covenant or provision hereof which under Article IX cannot be modified or amended without the consent of the Holder of
each Outstanding Security of such series affected. 
  
 Upon any
such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any
right consequent thereon. 
  
 Section 5.14 Undertaking For Costs.

  
 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, a court may in its discretion require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may
in its discretion assess reasonable costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to
require such an undertaking or to make such an assessment in any suit instituted by the Company or in any suit for the enforcement of the right to convert any Security in accordance with Article XIV. 
  
 Section 5.15 Waiver Of Usury, Stay Or Extension Laws. 
  
 The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
  
 ARTICLE VI 
 THE TRUSTEE

  
 Section 6.1 Certain Duties and Responsibilities. 
  
 The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act. Notwithstanding the foregoing, no provision of this Indenture shall require 

  

 34 

 
the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. No implied covenants or obligations shall be read
into this Indenture against the Trustee. The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith and reasonably believed by it to be within the discretion or power conferred upon it, or be responsible for the
consequences of any error of judgment reasonably made by it. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Company. Whether or not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 
  
 Section 6.2 Notice of Defaults. 
  
 The Trustee shall not be required to take notice, and shall not be deemed to have notice, of any default hereunder, except for Events of Default described
in paragraphs (1) and (2) of Section 5.1 unless the Trustee shall be notified specifically of the default in a written instrument or document delivered to it at its Corporate Trust Office by the Company or by the Holders of at least 10% of the
aggregate principal amount of Securities then Outstanding. In the absence of delivery of notice satisfying those requirements, the Trustee may assume conclusively that there is no default, except as noted above. If a default occurs hereunder with
respect to Securities of any series of which the Trustee has notice, the Trustee shall give the Holders of Securities of such series notice of such default as and to the extent provided by the Trust Indenture Act; provided, however, that in the case
of any default of the character specified in Section 5.1(4) with respect to Securities of such series, no such notice to Holders shall be given until at least 30 days after the occurrence thereof. For the purpose of this Section, the term
“default” means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to Securities of such series. 
  
 Section 6.3 Certain Rights of Trustee. 
  
 Subject to the provisions of Section 6.1: 
  
 (1) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or
parties; 
  
 (2) any request or direction of the
Company mentioned herein shall be sufficiently evidenced by a Company Request or Company Order, and any resolution of the Board of Directors shall be sufficiently evidenced by a Board Resolution; 
  

 35 

 (3) whenever in the administration of this Indenture the Trustee shall deem it desirable
that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence is expressly required by this Indenture to be delivered) is entitled to and may, in the absence of bad faith on
its part, rely upon an Officers’ Certificate; 
  
 (4) the Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good
faith and in reliance thereon; 
  
 (5) the
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction; 
  
 (6) the Trustee shall not be bound to monitor the Company, or analyze or review, or make any investigation into the facts or matters
stated in, any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may
make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the
Company, personally or by agent or attorney; and 
  
 (7) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of
any agent or attorney appointed with due care by it hereunder. 
  
 Section 6.4
Not Responsible for Recitals or Issuance of Securities. 
  
 The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and neither the Trustee nor any Authenticating Agent assumes any responsibility
for their correctness. The Trustee makes no representations as to the validity, sufficiency or priority of this Indenture or of the Securities. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof. 
  
 Section 6.5 May Hold
Securities And Act As Trustee Under Other Indentures. 
  
 The
Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, and their Affiliates and any directors, officers, employees or agents thereof, may become the

  

 36 

 
owner or pledgee of Securities and, subject to Sections 6.8 and 6.13, may otherwise deal with the Company with the same rights it would have if it were not
Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 
  
 Subject to Sections 6.8 and 6.13, nothing in this Indenture shall prohibit the Trustee from becoming and acting as trustee under other indentures under which other securities, or certificates of interest of
participation in other securities, of the Company are outstanding in the same manner as if it were not Trustee hereunder. 
  
 Section 6.6 Money Held In Trust. 
  
 Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise agreed with the Company. 
  
 Section 6.7 Compensation and Reimbursement. 
  
 The Company agrees: 
  
 (1) to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

  
 (2) except as otherwise expressly provided
herein, to pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by or on behalf of the Trustee in accordance with any provision of this Indenture (including the reasonable
compensation and the expenses and disbursements of its agents and counsel); 
  
 (3) to indemnify and hold the Trustee and its directors, officers, agents and employees (collectively the “Indemnitees”) harmless from and against any and all claims, liabilities, losses, damages, fines,
penalties, and expenses, including reasonable out-of-pocket and incidental expenses and reasonable legal fees (“Losses”) that may be imposed on, incurred by, or asserted against, the Indemnitees or any of them for following any
instructions or other directions upon which the Trustee is authorized to rely pursuant to the terms of this Indenture; and 
  
 (4) to indemnify the Indemnitees for, and to hold them harmless against, any Losses, to the extent incurred without gross negligence or
bad faith on their part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, or the Trustee’s exercise or performance of any of its powers or duties hereunder. 
  
 In no event shall the Trustee be liable for special, indirect or
consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 
  

 37 

 The provisions of this Section 6.7 shall survive the termination and discharge of this Indenture.

  
 Section 6.8 Conflicting Interests. 
  
 If the Trustee has acquired or shall acquire a conflicting interest within
the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by
such Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with respect to Securities of more than one series. 
  
 Section 6.9 Corporate Trustee Required; Eligibility. 
  
 There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may
also be Trustee hereunder for Securities of one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has (or if the Trustee is a member of a bank holding company system, its
bank holding company has) a combined capital and surplus of at least $50,000,000. If any such Person or bank holding company publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining
authority, then for the purposes of this Section and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person or bank holding company shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time the Trustee with respect to the Securities of any series shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and
with the effect hereinafter specified in this Article. 
  
 Section 6.10
Resignation and Removal; Appointment of Successor. 
  
 No
resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section
6.11. 
  
 The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
  

 38 

 The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company. 
  
 If at any time: 
  
 (1) the Trustee shall fail to comply with Section 6.8 after written request therefor by the Company or by any Holder who has been a bona
fide Holder of a Security for at least six months, or 
  
 (2) the Trustee shall cease to be eligible under Section 6.9 and shall fail to resign after written request therefor by the Company or by any such Holder, or 
  
 (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver
of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 
  
 then, in any such case, (A) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (B) subject to Section 5.14, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees. 
  
 If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to
the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be
appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section
6.11. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section
6.11, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so
appointed by the Company or the Holders and accepted appointment in the manner required by Section 6.11, the retiring Trustee may petition, or any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
  

 39 

 The Company shall give notice of each resignation and each removal of the Trustee with respect to the
Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 1.6. Each notice shall include the name of the successor
Trustee with respect to the Securities of such series and the address of its Corporate Trust Office. 
  
 Section 6.11 Acceptance of Appointment By Successor. 
  
 In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee
an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all
the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. 
  
 In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all)
series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and
which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or
those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and shall add to or change any of
the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such
Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of
such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such 

  

 40 

 
successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates. 
  
 Upon request of any such successor Trustee, the Company shall execute any and
all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be. 
  
 No successor Trustee shall accept its appointment unless at the time of such
acceptance such successor Trustee shall be qualified and eligible under this Article. 
  
 Section 6.12 Merger, Conversion, Consolidation or Succession to Business. 
  
 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party,
or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without
the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or
consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. 
  
 Section 6.13 Preferential Collection of Claims Against Company. 
  
 If and when the Trustee shall be or become a creditor of the Company (or any
other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor). 
  
 Section 6.14 Appointment of Authenticating Agent. 
  
 The Trustee may appoint an Authenticating Agent or Agents with respect to
one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to
Section 3.6, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be reasonably 

  

 41 

 
acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State
thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having (or if the Authenticating Agent is a member of a bank holding company system, its bank holding company has) a combined capital and surplus of not
less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining
authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time
an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section. 
  
 Any corporation into which an Authenticating Agent may be merged or converted
or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of
an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the
Authenticating Agent. 
  
 An Authenticating Agent may resign at
any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which
shall be reasonably acceptable to the Company and shall give notice of such appointment in the manner provided in Section 1.6 to all Holders of Securities of the series with respect to which such Authenticating Agent will serve. Any successor

affect the interests of the Holders of Securities of such series or any other series of Securities in any material respect. 
  
 Section 9.2 Supplemental Indentures with Consent of Holders. 
  
 With the consent of the Holders of a majority in principal amount of the Outstanding Securities of each series affected by such supplemental indenture, by

 (3) modify any of the provisions of this Section, Section 5.13 or Section 10.6, except to increase any such percentage or to provide that

 Section 10.2 Maintenance of Office or Agency. 
  
 The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange, where Securities of that series may be
surrendered for conversion and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change
in the location, of such office or agency. 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, 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. Unless otherwise provided in a supplemental indenture or

 The Company may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes 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 obligation to maintain an office or agency in each
Place of Payment for Securities of any series for such purposes. 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 10.3 Money for Securities Payments to Be Held In Trust. 
  
 If the Company shall at any time act as its own Paying Agent with respect to
any series of Securities, it will, on or before each due date of the principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay
the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. 
  

 49 

 Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, on or
prior to each due date of the principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such
Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 
  
 The Company will cause each Paying Agent for any series of Securities other than 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, that such Paying Agent will (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any
default by the Company (or any other obligor upon the Securities of that series) in the making of any payment in respect of the Securities of that series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust
by such Paying Agent for payment in respect of the Securities of that series. 
  
 The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, 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, 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 or any premium or interest on any Security of any series and remaining unclaimed for
a period ending on the earlier of the date that is ten Business Days prior to the date such money would escheat to the State or two years after such principal, premium or interest has become due and payable shall be paid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and any 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. All moneys held by the Trustee and subject to this Section shall be held uninvested and without liability for interest
thereon. 
  
 Section 10.4 Statement by Officers as to Default. 

 
 The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, an Officers’ Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may
have knowledge. The fiscal year of the Company currently ends on August 31; and the Company will give the Trustee prompt written notice of any change of its fiscal year.

of such series, the Company may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any covenant provided pursuant to Section 3.1(19) or 9.1(2) for the benefit
of the Holders of such series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or
generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. 
  
 ARTICLE XI 
 REDEMPTION OF SECURITIES

  
 Section 11.1 Applicability of Article. 
  
 Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 3.1 for such Securities) in accordance with this Article. 
  
 Section 11.2 Election to Redeem; Notice to Trustee. 
  
 The election of the Company to redeem any Securities shall be evidenced by a Board Resolution or in another manner specified
as contemplated by Section 3.1 for such Securities. In case of any redemption at the election of the Company of less than all the Securities of any series (including any such redemption affecting only a single Security), the Company shall, at least
45 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if
applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company
shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction. 
  

 51 

 Section 11.3 Selection by Trustee of Securities to be Redeemed. 
  
 If less than all the Securities of any series are to be redeemed (unless all
the Securities of such series and of a specified tenor are to be redeemed or unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected not more than 45 days prior to the Redemption Date by the
Trustee, from the Outstanding Securities of such series not previously called for redemption, by lot, whether by the Trustee or any Depositary, or in the Trustee’s discretion, on a pro-rata basis, provided that the unredeemed portion of the
principal amount of any Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. If less than all the Securities of such series and of a specified tenor are to be redeemed
(unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected not more than 45 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series and specified tenor
not previously called for redemption in accordance with the preceding sentence. 
  
 If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be
deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection. 

 
 The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption as aforesaid and, in case of any Securities selected for partial redemption as aforesaid, the principal amount thereof to be redeemed. 
  

The provisions of the two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether such Security
is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security. 
  
 For all purposes of this
Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities
which has been or is to be redeemed. 
  
 Section 11.4 Notice of Redemption.

  
 Notice of redemption shall be given by first-class mail,
postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to each Holder of Securities to be redeemed, at its address appearing in the Security
Register. 
  
 All notices of redemption shall state: 

 
 (1) the Redemption Date, 
  

 52 

 (2) the Redemption Price (including accrued interest, if any), 
  
 (3) if less than all the Outstanding Securities of any
series consisting of more than a single Security are to be redeemed, the identification (and, in the case of partial redemption of any such Securities, the principal amounts) of the particular Securities to be redeemed and, if less than all the
Outstanding Securities of any series consisting of a single Security are to be redeemed, the principal amount of the particular Security to be redeemed, 
  
 (4) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and, if
applicable, that interest thereon will cease to accrue on and after said date, 
  
 (5) the place or places where each such Security is to be surrendered for payment of the Redemption Price, 
  
 (6) if applicable, the conversion price, the date on which
the right to convert the principal of the Securities or the portions thereof to be redeemed will terminate, and the place or places where such Securities may be surrendered for conversion, and 
  
 (7) that the redemption is for a sinking fund, if such is
the case. 
  
 Notice of redemption of Securities to be redeemed at
the election of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company and shall be irrevocable. 
  
 Section 11.5 Deposit of Redemption Price. 
  

On or prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 10.3) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to
be redeemed on that date. 
  
 If any Security called for
redemption is converted, any money deposited with the Trustee or with a Paying Agent or so segregated and held in trust for the redemption of such Security shall (subject to the right of any Holder of such Security to receive interest as provided in
the last paragraph of Section 3.7) be paid to the Company on Company Request, or if then held by the Company, shall be discharged from such trust. 
  
 Section 11.6 Securities Payable on Redemption Date. 
  
 Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the Company shall default 

  

 53 

 
in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption
in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that, unless otherwise specified as contemplated by Section 3.1,
installments of interest whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 3.7. 
  
 If
any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security. 
  
 Section 11.7 Securities Redeemed In Part. 
  
 Any Security which is to be redeemed only in part shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or its attorney duly
authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. 
  
 ARTICLE XII 
 SINKING FUNDS 
  
 Section 12.1 Applicability of Article.

  
 The provisions of this Article shall be applicable to any
sinking fund for the retirement of Securities of any series except as otherwise specified as contemplated by Section 3.1 for such Securities. 
  
 The minimum amount of any sinking fund payment provided for by the terms of any Securities is herein referred to as a “mandatory sinking fund
payment,” and any payment in excess of such minimum amount provided for by the terms of such Securities is herein referred to as an “optional sinking fund payment.” If provided for by the terms of any Securities, the cash amount of
any sinking fund payment may be subject to reduction as provided in Section 12.2. Each sinking fund payment shall be applied to the redemption of Securities as provided for by the terms of such Securities. 
  
 Section 12.2 Satisfaction of Sinking Fund Payments with Securities. 
  
 The Company (1) may deliver Outstanding Securities of a series (other than
any previously called for redemption) and (2) may apply as a credit Securities of a series which have been redeemed either at the election of the Company pursuant to the terms 

  

 54 

 
of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in
satisfaction of all or any part of any sinking fund payment with respect to any Securities of such series required to be made pursuant to the terms of such Securities as and to the extent provided for by the terms of such Securities; provided that
the Securities to be so credited have not been previously so credited. The Securities to be so credited shall be received and credited for such purpose by the Trustee at the Redemption Price, as specified in the Securities so to be redeemed, for
redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 
  
 Section 12.3 Redemption of Securities for Sinking Fund.

Covenant Defeasance. 
  
 The Company may elect, at its option
at any time, to have Section 13.2 or Section 13.3 applied to any Securities or any series of Securities, as the case may be, designated pursuant to Section 3.1 as being defeasible pursuant to such Section 13.2 or 13.3, in accordance with any
applicable requirements provided pursuant to Section 3.1 and upon compliance with the conditions set forth below in this Article. Any such election shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section

 Section 13.2 Defeasance and Discharge.

  
 Upon the Company’s exercise of its option (if any)
to have this Section applied to any Securities or any series of Securities, as the case may be, the Company shall be deemed to have been discharged from its obligations with respect to such Securities as provided in this Section on and after the
date the conditions set forth in Section 13.4 are satisfied (hereinafter called “Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire 

  

 55 

 
indebtedness represented by such Securities and to have satisfied all its other obligations under such Securities and this Indenture insofar as such
Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following which shall survive until otherwise terminated or discharged hereunder: 
  
 (1) the rights of Holders of such Securities to receive,
solely from the trust fund described in Section 13.4 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Securities when payments are due; 
  
 (2) the Company’s obligations with respect to such
Securities under Sections 3.4, 3.5, 3.6, 10.2 and 10.3, and, if applicable, Article XIV; 
  
 (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder; and 
  
 (4) this Article. 
  
 Subject to compliance with this Article, the Company may exercise its option
(if any) to have this Section applied to any Securities notwithstanding the prior exercise of its option (if any) to have Section 13.3 applied to such Securities. 
  
 Section 13.3 Covenant Defeasance. 
  
 Upon the Company’s exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be:

  
 (1) the Company shall be released from its
obligations under Section 10.6, and any covenants provided pursuant to Section 3.1(19) or 9.1(2) or for the benefit of the Holders of such Securities and 
  
 (2) the occurrence of any event specified in Section 5.1(4) (with respect to Section 10.6 and any such covenants provided pursuant to
Section 3.1(19) or 9.1(2) shall be deemed not to be or result in an Event of Default, in each case with respect to such Securities as provided in this Section on and after the date the conditions set forth in Section 13.4 are satisfied (hereinafter
called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to such Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set
forth in any such specified Section (to the extent so specified in the case of Section 5.1(4)), whether directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason of any reference in any such Section to any
other provision herein or in any other document, but the remainder of this Indenture and such Securities shall be unaffected thereby. 
  

 56 

 Section 13.4 Conditions to Defeasance or Covenant Defeasance. 
  
 The following shall be the conditions to the application of Section 13.2 or
Section 13.3 to any Securities or any series of Securities, as the case may be: 
  
 (1) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee which satisfies the
requirements contemplated by Section 6.9 and agrees to comply with the provisions of this Article applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely
to, the benefits of the Holders of such Securities, (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later
than one day before the due date of any payment, money in an amount, or a combination thereof, in each case sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof
delivered to the Trustee, without the need to reinvest principal or interest, to pay and discharge, and which shall be applied by the Trustee (or any such other qualifying trustee) to pay and discharge, the principal of and any premium and interest
on such Securities on the respective Stated Maturities, in accordance with the terms of this Indenture and such Securities. As used herein, “U.S. Government Obligation” means (x) any security which is (i) a direct obligation of the United
States of America for the payment of which the full faith and credit of the United States of America is pledged or (ii) an obligation of a Person controlled or supervised by and acting as an agency or instrumentality of the United States of America
the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case (i) or (ii), is not callable or redeemable at the option of the issuer thereof, and (y) any depositary
receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S. Government Obligation which is specified in Clause (x) above and held by such bank for the account of the holder of such depositary
receipt, or with respect to any specific payment of principal of or interest on any U.S. Government Obligation which is so specified and held, provided that (except as required by law) such custodian is not authorized to make any deduction from the
amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of principal or interest evidenced by such depositary receipt. 
  
 (2) In the event of an election to have Section 13.2 apply
to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a
ruling or (B) since the date of this instrument, there has been a change in the applicable Federal income tax law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Securities will
not recognize gain or loss for Federal income tax purposes 

  

 57 

 
as a result of the deposit, Defeasance and discharge to be effected with respect to such Securities and will be subject to Federal income tax on the same
amount, in the same manner and at the same times as would be the case if such deposit, Defeasance and discharge were not to occur. 
  
 (3) In the event of an election to have Section 13.3 apply to any Securities or any series of Securities, as the case may be, the Company
shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance to be effected with
respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Covenant Defeasance were not to occur.

both would become, an Event of Default with respect to such Securities or any other Securities shall have occurred and be continuing at the time of such deposit or, with regard to any such event specified in Sections 5.1(5) and (6), at any time on
or prior to the 90th day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such 90th day). 
  
 (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust
Indenture Act (assuming all Securities are in default within the meaning of such Act). 
  
 (7) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other material
agreement or instrument to which the Company is a party or by which it is bound. 
  
 (8) Such Defeasance or Covenant Defeasance shall not result in the trust arising from such deposit constituting an investment company
within the meaning of the Investment Company Act unless such trust shall be registered under such Act or exempt from registration thereunder. 
  
 (9) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with. 
  

 58 

 Section 13.5 Deposited Money and US Government Obligations To Be Held In Trust; Miscellaneous Provisions.

  
 Subject to the provisions of the last paragraph of
Section 10.3, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 13.6, the Trustee and any such other trustee are
referred to collectively as the “Trustee”) pursuant to Section 13.4 in respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment,
either directly or through any such Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal and any
premium and interest, but money so held in trust need not be segregated from other funds except to the extent required by law. 
  
 The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 13.4 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of Outstanding Securities and is not paid or payable by the
Trustee. 
  
 Anything in this Article to the contrary
notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or U.S. Government Obligations held by it as provided in Section 13.4 with respect to any Securities which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant
Defeasance, as the case may be, with respect to such Securities. 
  
 Section
13.6 Reinstatement. 
  
 If the Trustee or the Paying Agent is
unable to apply any money in accordance with this Article with respect to any Securities by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations
under this Indenture and such Securities from which the Company has been discharged or released pursuant to Section 13.2 or 13.3 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 13.5 with respect to such Securities in accordance with this Article; provided, however, that if the Company makes any
payment of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money
so held in trust. 
  

 59 

 ARTICLE XIV 
 CONVERSION OF SECURITIES 
  
 Section
14.1 Applicability of Article. 
  
 The provisions of this
Article shall be applicable to the Securities of any series which are convertible into shares of Common Stock of the Company, and the issuance of such shares of Common Stock upon the conversion of such Securities, except as otherwise specified as
contemplated by Section 3.1 for the Securities of such series. 
  
 Section 14.2
Exercise of Conversion Privilege. 
  
 In order to exercise a
conversion privilege, the Holder of a Security of a series with such a privilege shall surrender such Security to the Company at the office or agency maintained for that purpose pursuant to Section 10.2, accompanied by a duly executed conversion
notice to the Company substantially in the form set forth in Section 2.4 stating that the Holder elects to convert such Security or a specified portion thereof. Such notice shall also state, if different from the name and address of such Holder, the
name or names (with address) in which the certificate or certificates for shares of Common Stock which shall be issuable on such conversion shall be issued. Securities surrendered for conversion shall (if so required by the Company or the Trustee)
be duly endorsed by or accompanied by instruments of transfer in forms satisfactory to the Company and the Trustee duly executed by the registered Holder or its attorney duly authorized in writing; and Securities so surrendered for conversion (in
whole or in part) during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date (excluding Securities or portions thereof called for redemption during the period
beginning at the close of business on a Regular Record Date and ending at the opening of business on the first Business Day after the next succeeding Interest Payment Date, or if such Interest Payment Date is not a Business Day, the second such
Business Day) shall also be accompanied by payment in funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of such Security then being converted, and such interest shall be
payable to such registered Holder notwithstanding the conversion of such Security, subject to the provisions of Section 3.7 relating to the payment of Defaulted Interest by the Company. As promptly as practicable after the receipt of such notice and
of any payment required pursuant to a Board Resolution, subject to Section 3.3, set forth, or determined in the manner provided, in an Officers’ Certificate, or established in one or more indentures supplemental hereto setting forth the terms
of such series of Security, and the surrender of such Security in accordance with such reasonable regulations as the Company may prescribe, the Company shall issue and shall deliver, at the office or agency at which such Security is surrendered, to
such Holder or on its written order, a certificate or certificates for the number of full shares of Common Stock issuable upon the conversion of such Security (or specified portion thereof), in accordance with the provisions of such Board
Resolution, Officers’ Certificate or supplemental indenture, and cash as provided therein in respect of any fractional share of such Common Stock otherwise issuable upon such conversion. Such conversion shall be deemed to have been effected

  

 60 

 
immediately prior to the close of business on the date on which such notice and such payment, if required, shall have been received in proper order for
conversion by the Company and such Security shall have been surrendered as aforesaid (unless such Holder shall have so surrendered such Security and shall have instructed the Company to effect the conversion on a particular date following such
surrender and such Holder shall be entitled to convert such Security on such date, in which case such conversion shall be deemed to be effected immediately prior to the close of business on such date) and at such time the rights of the Holder of
such Security as such Security Holder shall cease and the person or persons in whose name or names any certificate or certificates for shares of Common Stock of the Company shall be issuable upon such conversion shall be deemed to have become the
Holder or Holders of record of the shares represented thereby. Except as set forth above and subject to the final paragraph of Section 3.7, no payment or adjustment shall be made upon any conversion on account of any interest accrued on the
Securities (or any part thereof) surrendered for conversion or on account of any dividends on the Common Stock of the Company issued upon such conversion. In the case of any Security which is converted in part only, upon such conversion the Company
shall execute and the Trustee shall authenticate and deliver to or on the order of the Holder thereof, at the expense of the Company, a new Security or Securities of the same series, of authorized denominations, in aggregate principal amount equal
to the unconverted portion of such Security. 
  
 Section 14.3 No Fractional
Shares. 
  
 No fractional share of Common Stock of the
Company shall be issued upon conversions of Securities of any series. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion shall be computed
on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered. If, except for the provisions of this Section 14.3, any Holder of a Security or Securities would be
entitled to a fractional share of Common Stock of the Company upon the conversion of such Security or Securities, or specified portions thereof, the Company shall pay to such Holder an amount in cash equal to the current market value of such
fractional share computed, (i) if such Common Stock is listed or admitted to unlisted trading privileges on a national securities exchange or market, on the basis of the last reported sale price regular way on such exchange or market on the last
trading day prior to the date of conversion upon which such a sale shall have been effected, or (ii) if such Common Stock is not at the time so listed or admitted to unlisted trading privileges on a national securities exchange or market, on the
basis of the average of the bid and asked prices of such Common Stock in the over-the-counter market, on the last trading day prior to the date of conversion, as reported by the National Quotation Bureau, Incorporated or similar organization if the
National Quotation Bureau, Incorporated is no longer reporting such information, or if not so available, the fair market price as determined by the Board of Directors. For purposes of this Section, “trading day” shall mean each Monday,
Tuesday, Wednesday, Thursday and Friday other than any day on which the Common Stock is not traded on the Nasdaq National Market, or if the Common Stock is not traded on the Nasdaq National Market, on the principal exchange or market on which the
Common Stock is traded or quoted. 
  

 61 

 Section 14.4 Adjustment of Conversion Price. 
  
 The conversion price of Securities of any series that is convertible into Common Stock of the Company shall be adjusted for
any stock dividends, stock splits, reclassifications, combinations or similar transactions in accordance with the terms of the supplemental indenture or Board Resolutions setting forth the terms of the Securities of such series. Whenever the
conversion price is adjusted, the Company shall compute the adjusted conversion price in accordance with terms of the applicable Board Resolution or supplemental indenture and shall prepare an Officers’ Certificate setting forth the adjusted
conversion price and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall forthwith be filed at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 10.2
and, if different, with the Trustee. The Company shall forthwith cause a notice setting forth the adjusted conversion price to be mailed, first class postage prepaid, to each Holder of Securities of such series at its address appearing on the
Security Register and to any conversion agent other than the Trustee. 
  
 Section 14.5 Notice of Certain Corporate Actions. 
  
 In case: 
  
 (1) the Company shall
declare a dividend (or any other distribution) on its Common Stock payable otherwise than in cash out of its retained earnings (other than a dividend for which approval of any stockholders of the Company is required) that would require an adjustment
pursuant to Section 14.4; or 
  
 (2) the Company
shall authorize the granting to all or substantially all of the holders of its Common Stock of rights, options or warrants to subscribe for or purchase any shares of capital stock of any class or of any other rights (other than any such grant for
which approval of any stockholders of the Company is required); or 
  
 (3) of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding shares of Common Stock, or of any consolidation, merger or share exchange to which the Company
is a party and for which approval of any stockholders of the Company is required), or of the sale of all or substantially all of the assets of the Company; or 
  

(4) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; then the Company shall cause to be filed
with the Trustee, and shall cause to be mailed to all Holders at their last addresses as they shall appear in the Security Register, at least 20 days (or 10 days in any case specified in Clause (1) or (2) above) prior to the applicable record date
hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such dividend, distribution, rights, options or warrants, or, if a 

  

 62 

 
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, rights, options or
warrants are to be determined, or (ii) the date on which such reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders
of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, share exchange, sale, dissolution, liquidation or winding up.
If at any time the Trustee shall not be the conversion agent, a copy of such notice shall also forthwith be filed by the Company with the Trustee. 
  
 Section 14.6 Reservation of Shares of Common Stock. 
  
 The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose
of effecting the conversion of Securities, the full number of shares of Common Stock of the Company then issuable upon the conversion of all outstanding Securities of any series that has conversion rights. 
  
 Section 14.7 Payment of Certain Taxes Upon Conversion. 
  
 Except as provided in the next sentence, the Company will pay any and all
taxes that may be payable in respect of the issue or delivery of shares of its Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer
involved in the issue and delivery of shares of its Common Stock in a name other than that of the Holder of the Security or Securities to be converted, and no such issue or delivery shall be made unless and until the person requesting such issue has
paid to the Company the amount of any such tax, or has established, to the satisfaction of the Company, that such tax has been paid. 
  
 Section 14.8 Nonassessability. 
  
 The Company covenants that all shares of its Common Stock which may be issued upon conversion of Securities will upon issue in accordance with the terms
hereof be duly and validly issued and fully paid and nonassessable. 
  
 Section
14.9 Provision in Case of Consolidation, Merger or Sale of Assets. 
  
 In case of any consolidation or merger of the Company with or into any other Person, any merger of another Person with or into the Company (other than a merger which does not result in any reclassification, conversion, exchange or
cancellation of outstanding shares of Common Stock of the Company) or any conveyance, sale, transfer or lease of all or substantially all of the assets of the Company, the Person formed by such consolidation or resulting from such merger or which
acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security of a series then Outstanding that is convertible into Common Stock of the Company shall have the
right thereafter (which 

  

 63 

 
right shall be the exclusive conversion right thereafter available to said Holder), during the period such Security shall be convertible, to convert such
Security only into the kind and amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, sale, transfer or lease by a holder of the number of shares of Common Stock of the Company into which such Security
might have been converted immediately prior to such consolidation, merger, conveyance, sale, transfer or lease, assuming such holder of Common Stock of the Company (i) is not a Person with which the Company consolidated or merged with or into or
which merged into or with the Company or to which such conveyance, sale, transfer or lease was made, as the case may be (a “Constituent Person”), or an Affiliate of a Constituent Person and (ii) failed to exercise his rights of election,
if any, as to the kind or amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, sale, transfer or lease (provided that if the kind or amount of securities, cash and other property receivable upon such
consolidation, merger, conveyance, sale, transfer, or lease is not the same for each share of Common Stock of the Company held immediately prior to such consolidation, merger, conveyance, sale, transfer or lease by others than a Constituent Person
or an Affiliate thereof and in respect of which such rights of election shall not have been exercised (“Non-electing Share”), then for the purpose of this Section 14.9 the kind and amount of securities, cash and other property receivable
upon such consolidation, merger, conveyance, sale, transfer or lease by the holders of each Non-electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-electing Shares). Such supplemental indenture
shall provide for adjustments which, for events subsequent to the effective date of such supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article or in accordance with the terms of
the supplemental indenture or Board Resolutions setting forth the terms of such adjustments. The above provisions of this Section 14.9 shall similarly apply to successive consolidations, mergers, conveyances, sales, transfers or leases. Notice of
the execution of such a supplemental indenture shall be given by the Company to the Holder of each Security of a series that is convertible into Common Stock of the Company as provided in Section 1.6 promptly upon such execution. Neither the Trustee
nor any conversion agent, if any, shall be under any responsibility to determine the correctness of any provisions contained in any such supplemental indenture relating either to the kind or amount of shares of stock or other securities or property
or cash receivable by Holders of Securities of a series convertible into Common Stock of the Company upon the conversion of their Securities after any such consolidation, merger, conveyance, transfer, sale or lease or to any such adjustment, but may
accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, an Opinion of Counsel with respect thereto, which the Company shall cause to be furnished to the Trustee upon request. 
  
 Section 14.10 Duties of Trustee Regarding Conversion. 
  
 Neither the Trustee nor any conversion agent shall at any time be under any
duty or responsibility to any Holder of Securities of any series that is convertible into Common Stock of the Company to determine whether any facts exist which may require any adjustment of the conversion price, or with respect to the nature or
extent of any such adjustment when made, or with respect to the method employed, whether herein 

  

 64 

 
or in any supplemental indenture, any resolutions of the Board of Directors or written instrument executed by one or more officers of the Company provided to
be employed in making the same. Neither the Trustee nor any conversion agent shall be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock of the Company, or of any securities or property, which may
at any time be issued or delivered upon the conversion of any Securities and neither the Trustee nor any conversion agent makes any representation with respect thereto. Subject to the provisions of Section 6.1, neither the Trustee nor any conversion
agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of its Common Stock or stock certificates or other securities or property upon the surrender of any Security for the purpose of conversion or to
comply with any of the covenants of the Company contained in this Article XIV or in the applicable supplemental indenture, resolutions of the Board of Directors or written instrument executed by one or more duly authorized officers of the Company.

  
 Section 14.11 Repayment of Certain Funds Upon Conversion. 

 
 Any funds which at any time shall have been deposited by the Company or
on its behalf with the Trustee or any other paying agent for the purpose of paying the principal of, and premium, if any, and interest, if any, on any of the Securities (including, but not limited to, funds deposited for the sinking fund referred to
in Article XII hereof and funds deposited pursuant to Article XIII hereof) and which shall not be required for such purposes because of the conversion of such Securities as provided in this Article XIV shall after such conversion be repaid to the
Company by the Trustee upon the Company’s written request, accompanied by an Officer’s Certificate to that effect. 
  
 IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed as of the day and year first above written.
