prepared in accordance with Section 10.05, to the effect that 
 (i) the form or forms of such Securities have been established by or
pursuant to a resolution of the Board of Directors or by a supplemental indenture as permitted by Section 2.01 and 2.03 in conformity with the provisions of this Indenture; 

(ii) in the case of an underwritten offering, the terms of the Securities have been duly authorized and established in conformity with the
provisions of this Indenture, and, in the case of a Periodic Offering, certain terms of the Securities have been established pursuant to a resolution of the Board of Directors, an Officers’ Certificate or a supplemental indenture in accordance
with this Indenture, and when such other terms as are to be established pursuant to procedures set forth in an Issuer Order shall have been established, all such terms will have been duly authorized by the Issuer and will have been established in
conformity with the provisions of this Indenture;

and delivery, (ii) the Trustee shall authenticate and deliver Securities of such series for original issue from time to time, in an aggregate principal amount not exceeding the aggregate principal amount established for such series, pursuant to
an Issuer Order or pursuant to procedures acceptable to the Trustee as may be specified from time to time by an Issuer Order, (c) the maturity date or dates, original issue date or dates, interest rate or rates and any other terms of Securities
of such series shall be determined by an Issuer Order or pursuant to such procedures and (d) if provided for in such procedures, such Issuer Order may authorize authentication and delivery pursuant to oral or electronic instructions from the
Issuer or its duly authorized agent or agents, which oral instructions shall be promptly confirmed in writing. 
 The Trustee shall have the
right to decline to authenticate and deliver any Securities under this Section if the Trustee, being advised by counsel, determines that such action may not lawfully be taken by the Issuer or if the Trustee in good faith by its board of directors or
board of trustees, executive committee, or a trust committee of directors or trustees or Responsible Officers shall determine that such action would expose the Trustee to personal liability to existing Holders or would affect the Trustee’s own
rights, duties or immunities under the Securities, this Indenture or otherwise. 
 Section 2.05. Execution of Securities. The
Securities shall be signed on behalf of the Issuer by both (a) the chairman of its Board of Directors or any vice chairman of its Board of Directors or its chief executive officer, chief financial officer, president or any vice president and
(b) by its treasurer or any assistant treasurer or its secretary or any assistant secretary, under its corporate seal (if any) which may, but need not, be attested. Such signatures may be the manual or facsimile signatures of the present or any
future such officers. The seal of the Issuer (if any) may be in the form of a facsimile thereof and may be impressed, affixed, imprinted or otherwise reproduced on the Securities. Typographical and other minor errors or defects in any such
reproduction of the seal (if any) or any such signature shall not affect the validity or enforceability of any Security that has been duly authenticated and delivered by the Trustee. 

  
 10 








 In case any officer of the Issuer who shall have signed any of the Securities shall cease to be
such officer before the Security so signed shall be authenticated and delivered by the Trustee or disposed of by the Issuer, such Security nevertheless may be authenticated and delivered or disposed of as though the person who signed such Security
had not ceased to be such officer of the Issuer; and any Security may be signed on behalf of the Issuer by such persons as, at the actual date of the execution of such Security, shall be the proper officers of the Issuer, although at the date of the
execution and delivery of this Indenture any such person was not such an officer. 
 If the Issuer shall establish pursuant to
Section 2.03 that the Securities of a series are to be issued in the form of one or more Global Securities, then the Issuer shall execute and the Trustee shall, in accordance with this Section and the Issuer Order with respect to such series,
authenticate and deliver one or more Global Securities that (a) shall represent and shall be denominated in an amount equal to the aggregate principal amount of all of the Securities of such series having the same terms issued and not yet
canceled, (b) shall be registered in the name of the Depositary for such Global Security or Global Securities or the nominee of such Depositary, (c) shall be delivered by the Trustee to such Depositary or pursuant to such Depositary’s
instructions and (d) shall bear a legend substantially to the following effect: 
 UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART
FOR SECURITIES IN DEFINITIVE REGISTERED FORM, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO THE NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF SUCH DEPOSITARY OR BY
THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY. 
 Each Depositary designated
pursuant to Section 2.03 must, at the time of its designation and at all times while it serves as Depositary, be a clearing agency registered under the Securities Exchange Act of 1934, as amended, and any other applicable statute or regulation.

 Notwithstanding any other provision of this Section 2.05, unless and until it is exchanged in whole or in part for Securities in
definitive form, a Global Security representing all or a portion of the Securities of a series may not be transferred except as a whole by the Depositary for such series to a nominee of such Depositary or by a nominee of such Depositary to such
Depositary or another nominee of such Depositary or by such Depositary or any such nominee to a successor Depositary for such series or a nominee of such successor Depositary. 

If at any time the Depositary for any Securities of a series represented by one or more Global Securities notifies the Issuer that it is
unwilling or unable to continue as Depositary for such Securities or if at any time the Depositary for such Securities shall no longer be eligible under this Section 2.05, the Issuer shall appoint a successor Depositary eligible under this
Section 2.05 with respect to such Securities. If a successor Depositary eligible under this Section 2.05 for such Securities is not appointed by the Issuer within 90 days after the Issuer receives such notice or becomes aware of such
ineligibility, the Issuer’s election pursuant to Section 2.03 that such Securities be represented by one or more Global Securities shall no longer be effective and the Issuer will execute, and the Trustee, upon receipt of an Officers’
Certificate for the authentication and delivery of definitive Securities of such series, will authenticate and deliver, Securities of such series in definitive registered form without coupons, in any authorized denominations, in an aggregate
principal amount equal to the principal amount of the Global Security or Global Securities representing such Securities in exchange for such Global Security or Global Securities. 

The Issuer may at any time and in its sole discretion determine that the Securities of any series issued in the form of one or more Global
Securities shall no longer be represented by a Global Security or Global Securities. In such event the Issuer will execute, and the Trustee, upon receipt of an Issuer Order for the authentication and delivery of definitive Securities of such series,
will authenticate and deliver, Securities of such series in definitive registered form without coupons, in any authorized denominations, in an aggregate principal amount equal to the principal amount of the Global Security or Global Securities
representing such Securities, in exchange for such Global Security or Global Securities. 
 If specified by the Issuer pursuant to
Section 2.03 with respect to Securities represented by a Global Security, the Depositary for such Global Security may surrender such Global Security in exchange in whole or in part for Securities of the same series in definitive registered form
on such terms as are acceptable to the Issuer and such Depositary. Thereupon, the Issuer shall execute, and the Trustee shall authenticate and deliver, without service charge, 

(a) to the Person specified by such Depositary a new Security or Securities of the same series, of any authorized denominations as requested by
such Person, in an aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the Global Security; and 

(b) to such Depositary a new Global Security in a denomination equal to the difference, if any, between the principal amount of the surrendered
Global Security and the aggregate principal amount of Securities authenticated and delivered pursuant to clause (a) above. 

  
 11 








 Upon the exchange of a Global Security for Securities in definitive registered form without
coupons, in authorized denominations, such Global Security shall be canceled by the Trustee or an agent of the Issuer or the Trustee. Securities in definitive registered form without coupons issued in exchange for a Global Security pursuant to this
Section 2.05 shall be registered in such names and in such authorized denominations as the Depositary for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee or an
agent of the Issuer or the Trustee. The Trustee or such agent shall deliver such Securities to or as directed by the Persons in whose names such Securities are so registered. 

Section 2.06. Certificate of Authentication. Only such Securities as shall bear thereon a certificate of authentication
substantially in the form hereinbefore recited, executed by the Trustee by the manual signature of one of its authorized officers, shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the
Trustee upon any Security executed by the Issuer shall be conclusive evidence that the Security so authenticated has been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of this Indenture. 

Section 2.07. Denomination and Date of Securities; Payments of Interest. The Securities shall be issuable as registered securities
without coupons and in denominations as shall be specified as contemplated by Section 2.03. In the absence of any such specification with respect to the Securities of any series, the Securities of such series shall be issuable in denominations
of $1,000 and any multiple thereof. The Securities shall be numbered, lettered, or otherwise distinguished in such manner or in accordance with such plan as the officers of the Issuer executing the same may determine with the approval of the Trustee
as evidenced by the execution and authentication thereof. 
 Each Security shall be dated the date of its authentication, shall bear
interest, if any, from such date and shall be payable on the dates, in each case, which shall be specified as contemplated by Section 2.03. 

The person in whose name any Security of any series is registered at the close of business on any record date applicable to a particular
series with respect to any interest payment date for such series shall be entitled to receive the interest, if any, payable on such interest payment date notwithstanding any transfer or exchange of such Security subsequent to the record date and
prior to such interest payment date, except if and to the extent the Issuer shall default in the payment of the interest due on such interest payment date for such series, in which case such defaulted interest shall be paid to the persons in whose
names Outstanding Securities for such series are registered at the close of business on a subsequent record date (which shall be not less than five Business Days prior to the date of payment of such defaulted interest) established by notice given by
mail by or on behalf of the Issuer to the holders of Securities not less than 15 days preceding such subsequent record date. The term “record date” as used with respect to any interest payment date (except a date for payment of
defaulted interest) shall mean the date specified as such in the terms of the Securities of any particular series, or, if no such date is so specified, if such interest payment date is the first day of a calendar month, the fifteenth day of the next
preceding calendar month or, if such interest payment date is the fifteenth day of a calendar month, the first day of such calendar month, whether or not such record date is a Business Day. 

Section 2.08. Registration, Transfer and Exchange. The Issuer will keep or cause to be kept at each office or agency to be
maintained for the purpose as provided in Section 3.02 a register or registers in which, subject to such reasonable regulations as it may prescribe, it will register, and will register the transfer of, Securities as in this Article provided.
Such register shall be in written form in the English language or in any other form capable of being converted into such form within a reasonable time. At all reasonable times such register or registers shall be open for inspection by the Trustee.

 Upon due presentation for registration of transfer of any Security of any series at any such office or agency to be maintained for the
purpose as provided in Section 3.02, the Issuer shall execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees a new Security or Securities of the same series in authorized denominations for a like
aggregate principal amount. 
 Any Security or Securities of any series may be exchanged for a Security or Securities of the same series in
other authorized denominations, in an equal aggregate principal amount. Securities of any series to be exchanged shall be surrendered at any office or agency to be maintained by the Issuer for the purpose as provided in Section 3.02, and the
Issuer shall execute and the Trustee shall authenticate and deliver in exchange therefor the Security or Securities of the same series which the Securityholder making the exchange shall be entitled to receive, bearing numbers not contemporaneously
outstanding. 

  
 12 








 All Securities presented for registration of transfer, exchange, redemption or payment shall (if
so required by the Issuer or the Trustee) be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form reasonably satisfactory to the Issuer and the Trustee duly executed by, the holder or his attorney duly
authorized in writing. 
 The Issuer may require payment of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any exchange or registration of transfer of Securities. No service charge shall be made for any such transaction. 

The Issuer shall not be required to exchange or register a transfer of (a) any Securities of any series for a period of 15 days next
preceding the first mailing of notice of redemption of Securities of such series to be redeemed, or (b) any Securities selected, called or being called for redemption except, in the case of any Security where notice has been given that such
Security is to be redeemed in part, the portion thereof not so to be redeemed. 
 All Securities issued upon any transfer or exchange of
Securities shall be valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange. 

Section 2.09. Mutilated, Defaced, Destroyed, Lost and Stolen Securities. In case any temporary or definitive Security shall become
mutilated, defaced or be destroyed, lost or stolen, the Issuer in its discretion may execute, and upon the written request of any officer of the Issuer, the Trustee shall authenticate and deliver, a new Security of the same series, bearing a number
not contemporaneously outstanding, in exchange and substitution for the mutilated or defaced Security, or in lieu of and substitution for the Security so destroyed, lost or stolen. In every case, the applicant for a substitute Security shall furnish
to the Issuer and to the Trustee and any agent of the Issuer or the Trustee such security or indemnity as may be required by them to indemnify and defend and to save each of them harmless and, in every case of destruction, loss or theft, shall
furnish evidence to their reasonable satisfaction of the destruction, loss or theft of such Security and of the ownership thereof. 
 Upon
the issuance of any substitute Security, the Issuer 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) connected therewith. In case any Security which has matured or is about to mature or has been called for redemption in full shall become mutilated or defaced or be destroyed, lost or stolen, the Issuer may instead of issuing a substitute
Security, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated or defaced Security), if the applicant for such payment shall furnish to the Issuer and to the Trustee and any agent of the Issuer or the
Trustee such security or indemnity as any of them may require to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Issuer and the Trustee and any agent of the Issuer or the Trustee
evidence to their reasonable satisfaction of the destruction, loss or theft of such Security and of the ownership thereof. 
 Every
substitute Security of any series issued pursuant to the provisions of this Section by virtue of the fact that any such Security is destroyed, lost or stolen shall constitute an additional contractual obligation of the Issuer, whether or not the
destroyed, lost or stolen Security shall be at any time enforceable by anyone and that substitute Security shall be entitled to all the benefits of (but shall be subject to all the limitations of rights set forth in) this Indenture equally and
proportionately with any and all other Securities of such series duly authenticated and delivered hereunder. All Securities shall be held and owned upon the express condition that, to the extent permitted by law, the foregoing provisions are
exclusive with respect to the replacement or payment of mutilated, defaced or destroyed, lost or stolen Securities and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the
contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender. 

Section 2.10. Cancellation of Securities; Disposition Thereof. All Securities surrendered for payment, redemption, registration of
transfer or exchange, or for credit against any payment in respect of a sinking or analogous fund, if surrendered to the Issuer or any agent of the Issuer or of the Trustee, shall be delivered to the Trustee for cancellation or, if surrendered to
the Trustee, shall be canceled by it; and no Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled Securities held by it in accordance with its
customary procedures and deliver a certificate of disposition to the Issuer. If the Issuer shall acquire any of the Securities, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities
unless and until the same are delivered to the Trustee for cancellation. 
 Section 2.11. Temporary Securities. Pending the
preparation of definitive Securities for any series, the Issuer may execute and the Trustee shall authenticate and deliver temporary Securities for such series (printed, lithographed, typewritten or otherwise reproduced, in each case in form
reasonably satisfactory to the Trustee). Temporary Securities of any series shall be issuable as registered Securities without coupons, of any authorized denomination, and substantially in the form of the definitive Securities of such series but
with such omissions, insertions and variations as may be appropriate for temporary Securities, all as may be determined by the Issuer with the concurrence of the Trustee. Temporary Securities may contain such reference to any provisions of


  
 13 








 
this Indenture as may be appropriate. Every temporary Security shall be executed by the Issuer and be authenticated by the Trustee upon the same conditions and in substantially the same manner,
and with like effect, as the definitive Securities. Without unreasonable delay the Issuer shall execute and shall furnish definitive Securities of such series and thereupon temporary Securities of such series may be surrendered in exchange therefor
without charge at each office or agency to be maintained by the Issuer for that purpose pursuant to Section 3.02, and the Trustee shall authenticate and deliver in exchange for such temporary Securities of such series a like aggregate principal
amount of definitive Securities of the same series of authorized denominations. Until so exchanged, the temporary Securities of any series shall be entitled to the same benefits under this Indenture as definitive Securities of such series. 

Section 2.12. Computation of Interest. Except as otherwise specified as contemplated by Section 2.03 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 3 

COVENANTS OF THE ISSUER AND THE TRUSTEE 

Section 3.01. Payment of Principal and Interest. The Issuer covenants and agrees for the benefit of each series of Securities that
it will duly and punctually pay or cause to be paid the principal of, and interest on, each of the Securities of such series at the place or places, at the respective times and in the manner provided in such Securities. Each installment of interest
on the Securities of any series may be paid by mailing checks for such interest payable to or upon the written order of the holders of Securities entitled thereto as they shall appear on the registry books of the Issuer. 

Section 3.02. Offices for Payments, Etc. So long as any of the Securities remain Outstanding, the Issuer will maintain in The City
of New York, the following for each series: an office or agency (a) where the Securities may be presented for payment, (b) where the Securities may be presented for registration of transfer and for exchange as in this Indenture provided,
(c) where Securities may be surrendered for conversion and (d) where notices and demands to or upon the Issuer in respect of the Securities or of this Indenture may be served. The Issuer will give to the Trustee written notice of the
location of any such office or agency and of any change of location thereof. Unless otherwise specified in accordance with Section 2.03, the Issuer hereby initially designates the New York Agency as the office to be maintained by it for each
such purpose. In case the Issuer shall fail to so designate or maintain any such office or agency or shall fail to give such notice of the location or of any change in the location thereof, presentations and demands may be made and notices may be
served at the New York Agency. 
 Section 3.03. Appointment to Fill a Vacancy in Office of Trustee. The Issuer, whenever
necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 5.09, a Trustee, so that there shall at all times be a Trustee with respect to each series of Securities hereunder. 

Section 3.04. Paying Agents. Whenever the Issuer shall appoint a paying agent other than the Trustee with respect to the
Securities of any series, it will cause such paying agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section, 

(a) that it will hold all sums received by it as such agent for the payment of the principal of or interest on the Securities of such series
(whether such sums have been paid to it by the Issuer or by any other obligor on the Securities of such series) in trust for the benefit of the holders of the Securities of such series or of the Trustee, 

(b) that it will give the Trustee notice of any failure by the Issuer (or by any other obligor on the Securities of such series) to make any
payment of the principal of or interest on the Securities of such series when the same shall be due and payable, and 
 (c) that it will pay
any such sums so held by it in trust to the Trustee upon the Trustee’s written request at any time during the continuance of the failure referred to in clause (b) above. 

The Issuer will, on or prior to each due date of the principal of or interest on the Securities of such series, deposit with the paying agent
a sum sufficient to pay such principal or interest so becoming due, and (unless such paying agent is the Trustee) the Issuer will promptly notify the Trustee of any failure to take such action. 

If the Issuer shall act as its own paying agent with respect to the Securities of any series, it will, on or before each due date of the
principal of or interest on the Securities of such series, set aside, segregate and hold in trust for the benefit of the holders of the Securities of such series a sum sufficient to pay such principal or interest so becoming due. The Issuer will
promptly notify the Trustee of any failure to take such action. 

  
 14 








 Anything in this Section to the contrary notwithstanding, the Issuer may at any time, for the
purpose of obtaining a satisfaction and discharge with respect to one or more or all series of Securities hereunder, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust for any such series by the Issuer or any
paying agent hereunder, as required by this Section, such sums to be held by the Trustee upon the trusts herein contained. 
 Anything in
this Section to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section is subject to the provisions of Section 9.03 and 9.04. 

Section 3.05. Certificate of the Issuer. The Issuer will deliver to the Trustee, on or before a date not more than 120 days after
the end of each fiscal year of the Issuer ending after the date of this Indenture, a written statement signed by the following officers (one of whom shall be the principal executive, financial or accounting officer of the Issuer): the Chairman, the
President or a Vice President, and by the Treasurer, an Assistant Treasurer, the Comptroller, an Assistant Comptroller, the Secretary or the Assistant Secretary of the Issuer, stating whether or not, after a review under each signer’s
supervision of the activities of the Issuer during such year and of the Issuer’s performance under this Indenture, to the best knowledge, based on such review, of the signers thereof, the Issuer has fulfilled all of its obligations, conditions
and covenants under this Indenture throughout such year, and, if there has been a default in the fulfillment of any such obligation, condition or covenant specifying each default and the nature and status thereof. 

Section 3.06. Securityholders Lists. If and so long as the Trustee shall not be the Security registrar for the Securities of any
series, the Issuer will furnish or cause to be furnished to the Trustee a list in such form as the Trustee may reasonably require of the names and addresses of the holders of the Securities of such series pursuant to Section 312 of the Trust
Indenture Act of 1939 (a) semi-annually not more than 15 days after each record date for the payment of interest on such Securities, as hereinabove specified, as of such record date and on dates to be determined pursuant to Section 2.03
for non-interest bearing securities in each year, and (b) at such other times as the Trustee may request in writing, within thirty days after receipt by the Issuer of any such request as of a date not more than 15 days prior to the time such
information is furnished. 
 Section 3.07. Reports by the Issuer. The Issuer covenants to file with the Trustee, within 15 days
after the Issuer is required to file the same with the Commission, copies of the annual reports and of the information, documents, and other reports which the Issuer may be required to file with the Commission pursuant to Section 13 or
Section 15(d) of the Securities Exchange Act of 1934 or pursuant to Section 314 of the Trust Indenture Act of 1939. 

Section 3.08. Reports by the Trustee. Any Trustee’s report required under Section 313(a) of the Trust Indenture Act of
1939 shall be transmitted on or before July 15 in each year following the date hereof, so long as any Securities are Outstanding hereunder, and shall be dated as of a date convenient to the Trustee no more than 60 nor less than 45 days prior
thereto. At the time it delivers such report, the Trustee shall deliver a copy thereof to the Issuer. 
 ARTICLE 4 

REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT 

Section 4.01. Event of Default Defined; Acceleration of Maturity; Waiver of Default. “Event of Default” with
respect to Securities of any series wherever used herein, means each one of the following events which shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): 

(a) default in the payment of any installment of interest upon any of the Securities of such series as and when the same shall become due and
payable, and continuance of such default for a period of 30 days; or 
 (b) default in the payment of all or any part of the principal on
any of the Securities of such series as and when the same shall become due and payable either at maturity, upon redemption, by declaration or otherwise; or 

(c) default in the payment of any sinking fund installment as and when the same shall become due and payable by the terms of the Securities of
such series; or 
 (d) default in the performance, or breach, of any covenant or warranty of the Issuer in respect of the Securities of such
series (other than a covenant or warranty in respect of the Securities of such series a default in whose performance or whose breach is elsewhere in this Section specifically dealt with), and continuance of such default or breach for a period of 90
days after there has been given, by registered or certified mail, to the Issuer by the Trustee or to the Issuer and the Trustee by the Holders of at least 25% in aggregate principal amount of the Outstanding Securities of all series affected
thereby, 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 

  
 15 








 (e) a court having jurisdiction in the premises shall enter a decree or order for relief in
respect of the Issuer in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the
Issuer or for any substantial part of its property or ordering the winding up or liquidation of the Issuer’s affairs, and such decree or order shall remain unstayed and in effect for a period of 60 consecutive days; or 

(f) the Issuer shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law at the date of this Indenture
or hereafter in effect, or consent to the entry of an order for relief in an involuntary case under any such law, or consent to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee or sequestrator (or
similar official) of the Issuer or for any substantial part of its property, or make any general assignment for the benefit of creditors; 

(g) an event of default, as defined in any indenture or instrument evidencing or securing or under which the Issuer has at the date of this
Indenture or shall hereafter have outstanding, any Indebtedness in an amount exceeding $25,000,000, which default shall involve (i) the failure by the Issuer to make any payment when such Indebtedness is due and payable after demand has been
made and the passage of any applicable grace period and such failure shall have continued for a period of thirty days after written notice thereof to the Issuer and the Trustee by the holders of not less than 25% in aggregate principal amount of the
Securities of such series or (ii) a default in the payment of interest, premium, principal or a default in the payment of a sinking fund or redemption payment, which shall have resulted in such Indebtedness having been accelerated so that the
same shall be or become due and payable prior to the date on which the same would otherwise become due and payable, and such acceleration shall not be stayed, rescinded or annulled within ten days after written notice thereof to the Issuer and the
Trustee by the holders of at least 25% in aggregate principal amount of the Securities of such series; provided, however, that if such event of default under such indenture or instrument shall be remedied or cured by the Issuer or be
waived by the holders of such Indebtedness before any judgment or decree for the payment of the moneys due shall have been obtained or entered, then the Event of Default hereunder by reason thereof shall be deemed likewise to have been thereupon
remedied, cured or waived without further action upon the part of either the Trustee or any of the holders of the Securities of such series; or 

(h) any other Event of Default provided in the supplemental indenture or provided in or pursuant to the resolution of the Board of Directors
under which such series of Securities is issued or in the form of Security for such series. 
 If an Event of Default with respect to
Securities of such series occurs and is continuing, then, and in each and every such case, unless the principal of all of the Securities of such series shall have already become due and payable, either the Trustee or the Holders of not less than 25%
in aggregate principal amount of the Securities of such series then Outstanding hereunder (each such series voting as a separate class) by notice in writing to the Issuer (and to the Trustee if given by Securityholders), may declare the entire
principal (or, if the Securities of such series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of such series) of all Securities of such series and the interest accrued thereon, if any,
to be due and payable immediately, and upon any such declaration the same shall become immediately due and payable. 
 The foregoing
provisions, however, are subject to the condition that if, at any time after the principal (or, if the Securities are Original Issue Discount Securities, such portion of the principal as may be specified in the terms thereof) of the Securities of
any series shall have been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, the Issuer shall pay or shall deposit with the Trustee a sum
sufficient to pay all matured installments of interest upon all the Securities of such series and the principal of any and all Securities of such series which shall have become due otherwise than by acceleration (with interest upon such principal
and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest, at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in
the Securities of such series to the date of such payment or deposit) and such amount as shall be sufficient to cover reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other expenses and liabilities incurred, and all
advances made, by the Trustee except as a result of negligence or bad faith, and if any and all Events of Default under the Indenture, other than the non-payment of the principal of Securities which shall have become due by acceleration, shall have
been cured, waived or otherwise remedied as provided herein—then and in every such case the holders of a majority in aggregate principal amount of all the Securities of such series, each series voting as a separate class, then Outstanding, by
written notice to the Issuer and to the Trustee, may waive all defaults with respect to such series and rescind and annul such declaration and its consequences, but no such waiver or rescission and annulment shall extend to or shall affect any
subsequent default or shall impair any right consequent thereon. 

  
 16 








 For all purposes under this Indenture, if a portion of the principal of any Original Issue
Discount Securities shall have been accelerated and declared due and payable pursuant to the provisions hereof, then, from and after such declaration, unless such declaration has been rescinded and annulled, the principal amount of such Original
Issue Discount Securities shall be deemed, for all purposes hereunder, to be such portion of the principal thereof as shall be due and payable as a result of such acceleration, and payment of such portion of the principal thereof as shall be due and
payable as a result of such acceleration, together with interest, if any, thereon and all other amounts owing thereunder, shall constitute payment in full of such Original Issue Discount Securities. 

The Trustee shall not be charged with notice of any event of default referred to in Section 4.01(g) unless (i) an officer of the
Trustee assigned to its Corporate Trustee Administration Department shall have actual knowledge thereof or (ii) the Trustee shall have received written notice thereof from the Issuer, the holder of any Indebtedness referred to in
Section 4.01(g) or the holders of not less than 25% in aggregate principal amount of the Securities of any series. 

Section 4.02. Collection of Indebtedness by Trustee; Trustee May Prove Indebtedness. The Issuer covenants that (x) in case
default shall be made in the payment of any installment of interest on any of the Securities of any series when such interest shall have become due and payable, and such default shall have continued for a period of 30 days or (y) in case
default shall be made in the payment of all or any part of the principal of any of the Securities of any series when the same shall have become due and payable, whether upon maturity of the Securities of such series or upon any redemption or by
declaration or otherwise—then upon demand of the Trustee, the Issuer will pay to the Trustee for the benefit of the Holders of the Securities of such series the whole amount that then shall have become due and payable on all Securities of such
series for principal or interest, as the case may be (with interest to the date of such payment upon the overdue principal and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest at
the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities of such series); and in addition thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including reasonable compensation to the Trustee and each predecessor Trustee, their respective agents, attorneys and counsel, and any expenses and liabilities incurred, and all advances made, by the Trustee and each
predecessor Trustee except as a result of its negligence or bad faith. 
 Until such demand is made by the Trustee, the Issuer may pay the
principal of and interest on the Securities of any series to the registered holders, whether or not the principal of and interest on the Securities of such series be overdue. 

In case the Issuer shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust,
shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceedings to judgment or final decree, and may enforce any such
judgment or final decree against the Issuer or other obligor upon such Securities and collect in the manner provided by law out of the property of the Issuer or other obligor upon such Securities, wherever situated, the moneys adjudged or decreed to
be payable. 
 In case there shall be pending proceedings relative to the Issuer or any other obligor upon the Securities under Title 11 of
the United States Code or any other applicable Federal or state bankruptcy, insolvency or other similar law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been
appointed for or taken possession of the Issuer or its property or such other obligor, or in case of any other comparable judicial proceedings relative to the Issuer or other obligor upon the Securities of any series, or to the creditors or property
of the Issuer or such other obligor, the Trustee, irrespective of whether the principal of any Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any
demand pursuant to the provisions of this Section, shall be entitled and empowered, by intervention in such proceedings or otherwise: 
 (a)
to file and prove a claim or claims for the whole amount of principal and interest (or, if the Securities of any series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of such series)
owing and unpaid in respect of the Securities of any series, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation to the Trustee and
each predecessor Trustee, and their respective agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee, except as a result of negligence or bad
faith) and of the Securityholders allowed in any judicial proceedings relative to the Issuer or other obligor upon the Securities of any series, or to the creditors or property of the Issuer or such other obligor, 

(b) unless prohibited by applicable law and regulations, to vote on behalf of the holders of the Securities of any series in any election of a
trustee or a standby trustee in arrangement, reorganization, liquidation or other bankruptcy or insolvency proceedings or person performing similar functions in comparable proceedings, and 

  
 17 








 (c) to collect and receive any moneys or other property payable or deliverable on any such
claims, and to distribute all amounts received with respect to the claims of the Securityholders and of the Trustee on their behalf; and any trustee, receiver, or liquidator, custodian or other similar official is hereby authorized by each of the
Securityholders to make payments to the Trustee, and, in the event that the Trustee shall consent to the making of payments directly to the Securityholders, to pay to the Trustee such amounts as shall be sufficient to cover reasonable compensation
to the Trustee, each predecessor Trustee and their respective agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Trustee and each predecessor Trustee except as a result of negligence or bad
faith and all other amounts due to the Trustee or any predecessor Trustee pursuant to Section 5.06. 
 Nothing herein contained shall
be deemed to authorize the Trustee to authorize or consent to or vote for or accept or adopt on behalf of any Securityholder any plan or reorganization, arrangement, adjustment or composition affecting the Securities of any series or the rights of
any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Securityholder in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar person. 

All rights of action and of asserting claims under this Indenture, or under any of the Securities, may be enforced by the Trustee without the
possession of any of the Securities or the production thereof on any trial or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment, subject to the payment of the expenses, liabilities incurred, disbursements and compensation of the Trustee, each predecessor Trustee and their respective agents and attorneys, shall be for the ratable benefit of the holders of
the Securities in respect of which such action was taken. 
 In any proceedings brought by the Trustee (and also any proceedings involving
the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the holders of the Securities in respect to which such action was taken, and it shall not be necessary to make
any holders of such Securities parties to any such proceedings. 
 Section 4.03. Application of Proceeds. Any moneys collected
by the Trustee pursuant to this Article in respect of any series shall be applied in the following order at the date or dates fixed by the Trustee and, in case of the distribution of such moneys on account of principal or interest, upon presentation
of the several Securities in respect of which monies have been collected and stamping (or otherwise noting) thereon the payment, or issuing Securities of such series in reduced principal amounts in exchange for the presented Securities of like
series if only partially paid, or upon surrender thereof if fully paid: 
 FIRST: To the payment of costs and expenses applicable to such
series in respect of which monies have been collected, including reasonable compensation to the Trustee and each predecessor Trustee and their respective agents and attorneys and of all expenses and liabilities incurred, and all advances made, by
the Trustee and each predecessor Trustee except as a result of negligence or bad faith, and all other amounts due to the Trustee or any predecessor Trustee pursuant to Section 5.06; 

SECOND: In case the principal of the Securities of such series in respect of which moneys have been collected shall not have become and be then
due and payable, to the payment of interest on the Securities of such series in default in the order of the maturity of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the
overdue installments of interest at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in such Securities, such payments to be made ratably to the persons entitled thereto,
without discrimination or preference; 
 THIRD: In case the principal of the Securities of such series in respect of which moneys have been
collected shall have become and shall be then due and payable, to the payment of the whole amount then owing and unpaid upon all the Securities of such series for principal and interest, with interest upon the overdue principal, and (to the extent
that such interest has been collected by the Trustee) upon overdue installments of interest at the same rate as the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) specified in the Securities of such series;
and in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Securities of such series, then to the payment of such principal and interest or Yield to Maturity, without preference or priority of principal
over interest or Yield to Maturity, or of interest or Yield to Maturity over principal, or of any installment of interest over any other installment of interest, or of any Security of such series over any other Security of such series, ratably to
the aggregate of such principal and accrued and unpaid interest or Yield to Maturity; and 
 FOURTH: To the payment of the remainder, if any,
to the Issuer or any other person lawfully entitled thereto. 
 Section 4.04. Suits for Enforcement. In case an Event of Default
has occurred, has not been waived and is continuing, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any of such rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this
Indenture or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 

  
 18 








 Section 4.05. Restoration of Rights on Abandonment of Proceedings. In case the
Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee, then and in every such case the Issuer and
the Trustee shall be restored respectively to their former positions and rights hereunder, and all rights, remedies and powers of the Issuer, the Trustee and the Securityholders shall continue as though no such proceedings had been taken. 

Section 4.06. Limitations on Suits by Securityholders. No Holder of any Security of any series shall have any right by virtue or
by availing of any provision of this Indenture to institute any action or proceeding at law or in equity or in bankruptcy or otherwise upon or under or with respect to this Indenture, or for the appointment of a trustee, receiver, liquidator,
custodian or other similar official or for any other remedy hereunder, unless such Holder previously shall have given to the Trustee written notice of default and of the continuance thereof, as hereinbefore provided, and unless also the Holders of
not less than 25% in aggregate principal amount of the Securities of such series then Outstanding shall have made written request upon the Trustee to institute such action or proceedings in its own name as Trustee hereunder and shall have offered to
the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby and the Trustee for 60 days after its receipt of such notice, request and offer of indemnity shall have failed to
institute any such action or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 4.09; it being understood and intended, and being expressly covenanted by the taker and
Holder of every Security with every other taker and Holder and the Trustee, that no one or more Holders of Securities of any series shall have any right in any manner whatever by virtue or by availing of any provision of this Indenture to affect,
disturb or prejudice the rights of any other such Holder of Securities, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this Indenture, except in the manner herein provided and for
the equal, ratable and common benefit of all Holders of Securities of the applicable series. For the protection and enforcement of the provisions of this Section, each and every Securityholder and the Trustee shall be entitled to such relief as can
be given either at law or in equity. 
 Section 4.07. Unconditional Right of Securityholders to Institute Certain Suits.
Notwithstanding any other provision in this Indenture and any provision of any Security, the right of any Holder of any Security to receive payment of the principal of and interest on such Security on or after the respective due dates expressed or
provided for in such Security, or to institute suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 

Section 4.08. Powers and Remedies Cumulative; Delay or Omission Not Waiver of Default. Except as provided in Sections 2.09 and
4.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Securityholders 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. 
 No delay or omission of the Trustee or of any Securityholder to exercise any right
or power accruing upon any Event of Default occurring and continuing as aforesaid shall impair any such right or power or shall be construed to be a waiver of any such Event of Default or an acquiescence therein; and, subject to Section 4.06,
every power and remedy given by this Indenture or by law to the Trustee or to the Securityholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Securityholders. 

Section 4.09. Control by Securityholders. The Holders of a majority in aggregate principal amount of the Securities of each series
affected (with each series voting as a separate class) at the time Outstanding 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 by this Indenture; provided that such direction shall not be otherwise than in accordance with law and the provisions of this Indenture and provided further that
(subject to the provisions of Section 5.01) the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, shall determine that the action or proceeding so directed may not lawfully be taken
or if the Trustee in good faith by its board of directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee shall determine that the action or proceedings so directed would involve the Trustee in
personal liability or if the Trustee in good faith shall so determine that the actions or forbearances specified in or pursuant to such direction would be unduly prejudicial to the interests of Holders of the Securities of all series so affected not
joining in the giving of said direction, it being understood that (subject to Section 5.01) the Trustee shall have no duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders. 

  
 19 








 Nothing in this Indenture shall impair the right of the Trustee in its discretion to take any
action deemed proper by the Trustee and which is not inconsistent with such direction or directions by Securityholders. 

Section 4.10. Waiver of Past Defaults. Prior to a declaration of the acceleration of the maturity of the Securities of any series
as provided in Section 4.01, the Holders of a majority in aggregate principal amount of the Securities of such series at the time Outstanding (each such series voting as a separate class) may on behalf of the Holders of all the Securities of
such series waive any past default or Event of Default described in clause (d) or (g) of Section 4.01 which relates to less than all series of Securities then Outstanding, except a default in respect of a covenant or provision hereof
which cannot be modified or amended without the consent of each Holder affected as provided in Section 7.02. Prior to a declaration of acceleration of the maturity of the Securities of any series as provided in Section 4.01, the Holders of
Securities of a majority in principal amount of all the Securities then Outstanding (voting as one class) may on behalf of all Holders waive any past default or Event of Default referred to in said clause (d) or (g) which relates to all
series of Securities then Outstanding, or described in clause (e) or (f) of Section 4.01, except a default in respect of a covenant or provision hereof which cannot be modified or amended without the consent of the Holder of each
Security affected as provided in Section 7.02. In the case of any such waiver, the Issuer, the Trustee and the Holders of the Securities of each series affected shall be restored to their former positions and rights hereunder, respectively.

 Upon any such waiver, such default shall cease to exist and be deemed to have been cured and not to have occurred, and any Event of
Default arising therefrom shall be deemed to have been cured, and not to have occurred for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent
thereon. 
 Section 4.11. Trustee to Give Notice of Default, But May Withhold in Certain Circumstances. The Trustee shall give
to the Securityholders of any series, as the names and addresses of such Holders appear on the registry books, notice by mail of all defaults known to the Trustee which have occurred with respect to such series, such notice to be transmitted within
90 days after the occurrence thereof, unless such defaults shall have been cured before the giving of such notice (the term “default” or “defaults” for the purposes of this Section being hereby defined to mean any
event or condition which is, or with notice or lapse of time or both would become, an Event of Default); provided that, except in the case of default in the payment of the principal of or interest on any of the Securities of such series, or
in the payment of any sinking or purchase fund installment with respect to the Securities of such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust
committee of directors or trustees and/or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Securityholders of such series. 

Section 4.12. Right of Court to Require Filing of Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder
of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action
taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees,
against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit
instituted by any Securityholder or group of Securityholders of any series holding in the aggregate more than 10% in aggregate principal amount of the Securities of such series, or, in the case of any suit relating to or arising under clauses
(d) or (g) of Section 4.01 (if the suit relates to Securities of more than one but less than all series), 10% in aggregate principal amount of Securities Outstanding affected thereby, or in the case of any suit relating to or arising
under clauses (d) or (g) (if the suit relates to all the Securities then Outstanding), (e) or (f) of Section 4.01, 10% in aggregate principal amount of all Securities Outstanding, or to any suit instituted by any
Securityholder for the enforcement of the payment of the principal of or interest on any Security on or after the due date expressed in such Security. 

ARTICLE 5 
 CONCERNING THE TRUSTEE

 Section 5.01. Duties and Responsibilities of the Trustee; During Default; Prior to Default. With respect to the Holders of
any series of Securities issued hereunder, the Trustee, prior to the occurrence of an Event of Default with respect to the Securities of a particular series and after the curing or waiving of all Events of Default which may have occurred with
respect to such series, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default with respect to the Securities of a series has occurred (which has not been cured or waived)
the Trustee shall with respect to such series of Securities exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the
circumstances in the conduct of his own affairs. 

  
 20 








 No provision of this Indenture shall be construed to relieve the Trustee from liability for its
own negligent action, its own negligent failure to act or its own willful misconduct, except that 
 (a) prior to the occurrence of an Event
of Default with respect to the Securities of any series and after the curing or waiving of all such Events of Default with respect to such series which may have occurred: 

(i) the duties and obligations of the Trustee with respect to the Securities of such series shall be determined solely by the express
provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture
against the Trustee; and 
 (ii) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth
of the statements and the correctness of the opinions expressed therein, upon any statements, certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such statements,
certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture;

 (b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Responsible Officers of the
Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (c) the Trustee shall not be
liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders pursuant to Section 4.09 relating to the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture. 
 None of the provisions
contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there shall be
reasonable ground for believing that the repayment of such funds or adequate indemnity against such liability is not reasonably assured to it. 

The provisions of this Section 5.01 are in furtherance of and subject to Sections 315 and 316 of the Trust Indenture Act of 1939. 

Section 5.02. Certain Rights of the Trustee. In furtherance of and subject to the Trust Indenture Act of 1939, and subject to
Section 5.01: 
 (a) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution,
Officers’ Certificate or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, note, coupon, security or other paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties; 
 (b) any request, direction, order or demand of the Issuer mentioned herein shall be
sufficiently evidenced by an Officers’ Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to the Trustee by a copy thereof certified by the
secretary or an assistant secretary of the Issuer; 
 (c) the Trustee may consult with counsel and any advice or Opinion of Counsel shall be
full and complete authorization and protection in respect of any action taken, suffered or omitted to be taken by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 

(d) the Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this Indenture at the request, order or
direction of any of the Securityholders pursuant to the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred
therein or thereby; 
 (e) the Trustee shall not be liable for any action taken or omitted by it in good faith and believed by it to be
authorized or within the discretion, rights or powers conferred upon it by this Indenture; 
 (f) prior to the occurrence of an Event of
Default hereunder and after the curing or waiving of all Events of Default, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, appraisal, bond, debenture, note, coupon, security, or other paper or document unless requested in writing so to do by the Holders of not less than a majority in aggregate principal amount of the Securities of all
series affected then Outstanding; provided that, if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee,
not reasonably 

  
 21 








 
assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require reasonable indemnity against such expenses or liabilities as a condition to
proceeding; the reasonable expenses of every such investigation shall be paid by the Issuer or, if paid by the Trustee or any predecessor trustee, shall be repaid by the Issuer upon demand; and 

(g) 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 not regularly in its employ and the Trustee shall not be responsible for any misconduct or negligence on the part of any such agent or attorney appointed with due care by it hereunder. 

Section 5.03. Trustee Not Responsible for Recitals, Disposition of Securities or Application of Proceeds Thereof. The recitals
contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Issuer, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no
representation as to the validity or sufficiency of this Indenture or of the Securities. The Trustee shall not be accountable for the use or application by the Issuer of any of the Securities or of the proceeds thereof. 

Section 5.04. Trustee and Agents May Hold Securities, Etc. The Trustee or any agent of the Issuer or the Trustee, in its
individual or any other capacity, may become the owner or pledgee of Securities with the same rights it would have if it were not the Trustee or such agent and may otherwise deal with the Issuer and receive, collect, hold and retain collections from
the Issuer with the same rights it would have if it were not the Trustee or such agent. 
 Section 5.05. Moneys Held by Trustee.
Subject to the provisions of Section 9.04 hereof, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds
except to the extent required by mandatory provisions of law. Neither the Trustee nor any agent of the Issuer or the Trustee shall be under any liability for interest on any moneys received by it hereunder. 

Section 5.06. Compensation and Indemnification of Trustee and Its Prior Claim. The Issuer covenants and agrees to pay to the
Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) and the Issuer covenants and agrees to pay
or reimburse the Trustee and each predecessor Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by or on behalf of it in accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of all agents and other persons not regularly in its employ) except to the extent any such expense, disbursement or advance may arise from its negligence or bad faith. The
Issuer also covenants to indemnify the Trustee and each predecessor Trustee for, and to hold it harmless against, any loss, liability or expense arising out of or in connection with the acceptance or administration of this Indenture or the trusts
hereunder and the performance of its duties hereunder, including the costs and expenses of defending itself against or investigating any claim of liability in the premises, except to the extent such loss, liability or expense is due to the
negligence or bad faith of the Trustee or such predecessor Trustee. The obligations of the Issuer under this Section to compensate and indemnify the Trustee and each predecessor Trustee and to pay or reimburse the Trustee and each predecessor
Trustee for expenses, disbursements and advances shall constitute additional Indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture. Such additional Indebtedness shall be a senior claim to that of the Securities
upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the holders of particular Securities, and the Securities are hereby subordinated to such senior claim. 

Section 5.07. Right of Trustee to Rely on Officers’ Certificate, Etc. Subject to Sections 5.01 and 5.02, whenever in the
administration of the trusts of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering or omitting any action hereunder, such matter (unless other evidence in respect
thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee, and such
certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under the provisions of this Indenture upon the faith thereof. 

Section 5.08. Persons Eligible for Appointment as Trustee. The Trustee for each series of Securities hereunder shall at all times
be a corporation having a combined capital and surplus of at least $50,000,000, and which is eligible in accordance with the provisions of Section 310(a) of the Trust Indenture Act of 1939. If such corporation publishes reports of condition at
least annually, pursuant to law or to the requirements of a Federal, State or District of Columbia supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be
its combined capital and surplus as set forth in its most recent report of condition so published. 
 Section 5.09. Resignation and
Removal; Appointment of Successor Trustee. (a) The Trustee, or any trustee or trustees hereafter appointed, may at any time resign with respect to one or more or all series of Securities by giving written notice of resignation to the


  
 22 








 
Issuer and by mailing notice thereof by first class mail to Holders of the applicable series of Securities at their last addresses as they shall appear on the Security register. Upon receiving
such notice of resignation, the Issuer shall promptly appoint a successor trustee or trustees with respect to the applicable series by written instrument in duplicate, executed by authority of the Board of Directors, one copy of which instrument
shall be delivered to the resigning Trustee and one copy to the successor trustee or trustees. If no successor trustee shall have been so appointed with respect to any series and have accepted appointment within 30 days after the mailing of such
notice of resignation, the resigning trustee may petition any court of competent jurisdiction for the appointment of a successor trustee, or any Securityholder who has been a bona fide Holder of a Security or Securities of the applicable series for
at least six months may, subject to the provisions of Section 4.12, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any,
as it may deem proper and prescribe, appoint a successor trustee. 
 (b) In case at any time any of the following shall occur: 

(i) the Trustee shall fail to comply with the provisions of Section 310(b) of the Trust Indenture Act of 1939 with respect to any series
of Securities after written request therefor by the Issuer or by any Securityholder who has been a bona fide Holder of a Security or Securities of such series for at least six months; or 

(ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 310(a) of the Trust Indenture Act of 1939 and
shall fail to resign after written request therefor by the Issuer or by any Securityholder; or 
 (iii) the Trustee shall become incapable of
acting with respect to any series of Securities, or shall be adjudged a bankrupt or insolvent, or a receiver or liquidator of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of
its property or affairs for the purpose of rehabilitation, conservation or liquidation; 
 then, in any such case, the Issuer may remove the Trustee with
respect to the applicable series of Securities and appoint a successor trustee for such series by written instrument, in duplicate, executed by order of the Board of Directors of the Issuer, one copy of which instrument shall be delivered to the
Trustee so removed and one copy to the successor trustee, or, subject to Section 315(e) of the Trust Indenture Act of 1939, any Securityholder who has been a bona fide Holder of a Security or Securities 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 removal of the Trustee and the appointment of a successor trustee with respect to such series. Such court may thereupon, after such
notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. 
 (c) The Holders of a majority in
aggregate principal amount of the Securities of each series at the time Outstanding may at any time remove the Trustee with respect to Securities of such series and appoint a successor trustee with respect to the Securities of such series by
delivering to the Trustee so removed, to the successor trustee so appointed and to the Issuer the evidence provided for in Section 6.01 of the action in that regard taken by the Securityholders. 

(d) Any resignation or removal of the Trustee with respect to any series and any appointment of a successor trustee with respect to such
series pursuant to any of the provisions of this Section 5.09 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 5.10. 

Section 5.10. Acceptance of Appointment by Successor Trustee. Any successor trustee appointed as provided in Section 5.09
shall execute and deliver to the Issuer and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee with respect to all or any applicable series shall become
effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all rights, powers, duties and obligations with respect to such series of its predecessor hereunder, with like effect as if originally named
as trustee for such series hereunder; but, nevertheless, on the written request of the Issuer or of the successor trustee, upon payment of its charges then unpaid, the trustee ceasing to act shall, subject to Section 9.04, pay over to the
successor trustee all moneys at the time held by it hereunder and shall execute and deliver an instrument transferring to such successor trustee all such rights, powers, duties and obligations. Upon request of any such successor trustee, the Issuer
shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a prior claim upon all property or
funds held or collected by such trustee to secure any amounts then due it pursuant to the provisions of Section 5.06. 
 If a successor
trustee is appointed with respect to the Securities of one or more (but not all) series, the Issuer, the predecessor Trustee and each successor trustee with respect to the Securities of any applicable series shall execute and deliver an indenture
supplemental hereto which shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the predecessor Trustee with respect to the Securities of any series as to which the
predecessor Trustee is not retiring shall continue to be vested in the predecessor Trustee, and shall add to or change any of the provisions of this Indenture as 

  
 23 








 
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 under separate indentures. 

Upon acceptance of appointment by any successor trustee as provided in this Section 5.10, the Issuer shall mail notice thereof by
first-class mail to the Holders of Securities of any series for which such successor trustee is acting as trustee at their last addresses as they shall appear in the Security register. If the acceptance of appointment is substantially
contemporaneous with the resignation, then the notice called for by the preceding sentence may be combined with the notice called for by Section 5.09. If the Issuer fails to mail such notice within ten days after acceptance of appointment by
the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Issuer. 
 Section 5.11.
Merger, Conversion, Consolidation or Succession to Business of Trustee. 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 that such corporation shall
be eligible under the provisions of Section 5.08, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. 

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

Section 5.12. Preferential Collection of Claims Against the Issuer. Reference is made to Section 311 of the Trust Indenture
Act of 1939, as amended. 
 ARTICLE 6 

CONCERNING THE SECURITYHOLDERS 

Section 6.01. Evidence of Action Taken by Securityholders. Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by a specified percentage in principal amount of the Securityholders of any or all series may be embodied in and evidenced by one or more instruments of substantially similar tenor
signed by such specified percentage of Securityholders in person or by agent 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. Proof of execution of any instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 5.01 and 5.02) conclusive in favor of the Trustee and the Issuer, if made in
the manner provided in this Article. 
 Section 6.02. Proof of Execution of Instruments and of Holding of Securities; Record
Date. Subject to Sections 5.01 and 5.02, the execution of any instrument by a Securityholder or his agent or proxy may be proved in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as
shall be reasonably satisfactory to the Trustee. The holding of Securities shall be proved by the Security register or by a certificate of the registrar thereof. The Issuer may set a record date for purposes of determining the identity of holders of
Securities of any series entitled to vote or consent to any action referred to in Section 6.01 which record date may be set at any time or from time to time by notice to the Trustee, for any date or dates (in the case of any adjournment or
reconsideration) not more than 60 days nor less than five days prior to the proposed date of such vote or consent, and thereafter, notwithstanding any other provisions hereof, only holders of Securities of such series of record on such record date
shall be entitled to so vote or give such consent or revoke such vote or consent. 
 Section 6.03. Holders to Be Treated as
Owners. The Issuer, the Trustee and any agent of the Issuer or the Trustee may deem and treat the person in whose name any Security shall be registered upon the Security register for such series as the absolute owner of such Security (whether or
not such Security shall be overdue and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment of or on account of the principal of and, subject to the provisions of this Indenture, interest on such
Security and for all other purposes; and neither the Issuer nor the Trustee nor any agent of the Issuer or the Trustee shall be affected by any notice to the contrary. All such payments so made to any such person, or upon his order, shall be valid,
and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon any such Security. 

  
 24 








 Section 6.04. Securities Owned by Issuer Deemed Not Outstanding. In determining
whether the Holders of the requisite aggregate principal amount of Outstanding Securities of any or all series have concurred in any direction, consent or waiver under this Indenture, Securities which are owned by the Issuer or any other obligor on
the Securities or by any person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer or any other obligor on the Securities shall be disregarded and deemed not to be Outstanding for the
purpose of any such determination, except that for the purpose of determining whether the Trustee shall be protected in relying on any such direction, consent or waiver only Securities which the Trustee knows are so owned shall be so disregarded.
Securities so owned which have been pledged in good faith may be regarded as Outstanding if the pledgee establishes to the reasonable satisfaction of the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee
is not the Issuer or any other obligor upon the Securities or any person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer or any other obligor on the Securities. In case of a dispute as
to such right, the advice of counsel shall be full protection in respect of any decision made by the Trustee in accordance with such advice. Upon request of the Trustee, the Issuer shall furnish to the Trustee promptly an Officers’ Certificate
listing and identifying all Securities, if any, known by the Issuer to be owned or held by or for the account of any of the above-described persons; and, subject to Sections 5.01 and 5.02, the Trustee shall be entitled to accept such Officers’
Certificate as conclusive evidence of the facts therein set forth and of the fact that all Securities not listed therein are Outstanding for the purpose of any such determination. 

Section 6.05. Right of Revocation of Action Taken. At any time prior to (but not after) the evidencing to the Trustee, as provided
in Section 6.01, of the taking of any action by the Holders of the percentage in aggregate principal amount of the Securities of any or all series, as the case may be, specified in this Indenture in connection with such action, any Holder of a
Security the serial number of which is shown by the evidence to be included among the serial numbers of the Securities the Holders of which have consented to such action may, by filing written notice at the Corporate Trust Office and upon proof of
holding as provided in this Article, revoke such action so far as concerns such Security. Except as aforesaid any such action taken by the Holder of any Security shall be conclusive and binding upon such Holder and upon all future Holders and owners
of such Security and of any Securities issued in exchange or substitution therefor or on registration of transfer thereof, irrespective of whether or not any notation in regard thereto is made upon any such Security. Any action taken by the Holders
of the percentage in aggregate principal amount of the Securities of any or all series, as the case may be, specified in this Indenture in connection with such action shall be conclusively binding upon the Issuer, the Trustee and the Holders of all
the Securities affected by such action. 
 ARTICLE 7 

SUPPLEMENTAL INDENTURES 

Section 7.01. Supplemental Indentures Without Consent of Securityholders. The Issuer, when authorized by a resolution of its Board
of Directors (which resolution may provide general terms or parameters for such action and may provide that the specific terms of such action may be determined in accordance with or pursuant to an Issuer Order), and the Trustee may from time to time
and at any time enter into an indenture or indentures supplemental hereto for one or more of the following purposes: 
 (a) to convey,
transfer, assign, mortgage or pledge to the Trustee as security for the Securities of one or more series any property or assets; 
 (b) to
evidence the succession of another corporation to the Issuer, or successive successions, and the assumption by the successor corporation of the covenants, agreements and obligations of the Issuer pursuant to Article 8; 

(c) to add to the covenants of the Issuer such further covenants, restrictions, conditions or provisions as its Board of Directors and the
Trustee shall consider to be for the protection of the Holders of Securities, and to make the occurrence, or the occurrence and continuance, of a default in any such additional covenants, restrictions, conditions or provisions an Event of Default
permitting the enforcement of all or any of the several remedies provided in this Indenture as herein set forth; provided, that in respect of any such additional covenant, restriction, condition or provision such supplemental indenture may
provide for a particular period of grace after default (which period may be shorter or longer than that allowed in the case of other defaults) or may provide for an immediate enforcement upon such an Event of Default or may limit the remedies
available to the Trustee upon such an Event of Default or may limit the right of the Holders of a majority in aggregate principal amount of the Securities of such series to waive such an Event of Default; 

(d) to cure any ambiguity or to correct or supplement any provision contained herein or in any supplemental indenture, which may be defective
or inconsistent with any other provision contained herein or in any supplemental indenture; or to make such other 

  
 25 








 
provisions in regard to matters or questions arising under this Indenture or under any supplemental indenture as the Board of Directors may deem necessary or desirable; provided that no
such action shall adversely affect the interests of the Holders of the Securities in any material respect; 
 (e) to establish the form or
terms of Securities of any series as permitted by Sections 2.01 and 2.03; and 
 (f) to make provision with respect to the conversion
rights, if any, of Holders of Securities pursuant to the requirements of Article 14 hereof; and 
 (g) to evidence and provide for the
acceptance of appointment hereunder by a successor trustee with respect to the Securities of one or more series and to 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, pursuant to the requirements of Section 5.10. 
 The Trustee is hereby authorized to
join with the Issuer in the execution of any such supplemental indenture, to make any further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any
property thereunder, but the Trustee shall not be obligated to enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 

Any supplemental indenture authorized by the provisions of this Section may be executed without the consent of the Holders of any of the
Securities at the time Outstanding, notwithstanding any of the provisions of Section 7.02. 
 Section 7.02. Supplemental
Indentures With Consent of Securityholders. With the consent (evidenced as provided in Article 6) of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of each series affected by such
supplemental indenture, the Issuer, when authorized by a resolution of its Board of Directors, and the Trustee may, from time to time and at any time, enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Securities of each such series; provided, that no such supplemental
indenture shall (a) extend the final maturity of any Security, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any amount payable on redemption thereof or reduce the amount
of the principal of an Original Issue Discount Security that would be due and payable upon an acceleration of the maturity thereof pursuant to Section 4.01 or the amount thereof provable in bankruptcy pursuant to Section 4.02, or impair or
affect the right of any Securityholder to institute suit for the payment thereof or, if the Securities provide therefor, any right of repayment at the option of the Securityholder without the consent of the Holder of each Security so affected, or
adversely affect the right to convert any Security as provided in Article 14 or modify the provisions of this Indenture with respect to the subordination of the Securities in a manner adverse to the Holders, or (b) reduce the aforesaid
percentage of Securities of any series, the consent of the Holders of which is required for any such supplemental indenture, without the consent of the Holders of each Security so affected. 

A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities, or which modifies the rights of holders of Securities of such series with respect to such covenant or provision, shall be deemed not to affect the rights under this Indenture of
the holders of Securities of any other series. 
 Upon the request of the Issuer, accompanied by a copy of a resolution of the Board of
Directors certified by the secretary or an assistant secretary of the Issuer authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Securityholders as aforesaid and other
documents, if any, required by Section 6.01, the Trustee shall join with the Issuer in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture. 

It shall not be necessary for the consent of the Securityholders under this Section to approve the particular form of any proposed
supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. 
 Promptly after the execution by
the Issuer and the Trustee of any supplemental indenture pursuant to the provisions of this Section, the Issuer shall mail a notice thereof by first class mail to the Holders of Securities of each series affected thereby at their addresses as they
shall appear on the registry books of the Issuer, setting forth in general terms the substance of such supplemental indenture. Any failure of the Issuer to mail such notice, or any defect therein, shall not, however, in any way impair or affect the
validity of any such supplemental indenture. 

  
 26 








 Section 7.03. Effect of Supplemental Indenture. Upon the execution of any
supplemental indenture pursuant to the provisions hereof, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this
Indenture of the Trustee, the Issuer and the Holders of Securities of each series affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and
conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 

Section 7.04. Documents to Be Given to Trustee. The Trustee, subject to the provisions of Sections 5.01 and 5.02, may receive an
Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any supplemental indenture executed pursuant to this Article 7 complies with the applicable provisions of this Indenture. 

Section 7.05. Notation on Securities in Respect of Supplemental Indentures. Securities of any series authenticated and delivered
after the execution of any supplemental indenture pursuant to the provisions of this Article may bear a notation in form approved by the Trustee for such series as to any matter provided for by such supplemental indenture. If the Issuer or the
Trustee shall so determine, new Securities of any series so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may be prepared by the
Issuer, authenticated by the Trustee and delivered in exchange for the Securities of such series then Outstanding. 
 Section 7.06.
Subordination Unimpaired. No supplemental indenture executed pursuant to this Article 7 shall adversely affect the rights of any holder of Senior Indebtedness under Article 13 without the consent of such holder. 

ARTICLE 8 
 CONSOLIDATION, MERGER,
SALE OR CONVEYANCE 
 Section 8.01. Issuer May Consolidate, Etc. on Certain Terms. The Issuer covenants that it will not merge
or consolidate with any other corporation or sell or convey all or substantially all of its assets to any Person, unless (a) either the Issuer shall be the continuing corporation, or the successor corporation or the Person which acquires by
sale or conveyance substantially all the assets of the Issuer (if other than the Issuer) shall be a corporation organized under the laws of the United States of America or any State thereof and shall expressly assume the due and punctual payment of
the principal of and interest on all the Securities, according to their tenor, and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed or observed by the Issuer and shall have
provided for conversion rights in accordance with Section 14.11, by supplemental indenture in form reasonably satisfactory to the Trustee, executed and delivered to the Trustee by such corporation, and (b) the Issuer or such successor
corporation, as the case may be, shall not, immediately after such merger or consolidation, or such sale or conveyance, be in default in the performance of any such covenant or condition of this Indenture. 

Section 8.02. Successor Corporation Substituted. In case of any such consolidation, merger, sale or conveyance, and following such
an assumption by the successor corporation, such successor corporation shall succeed to and be substituted for the Issuer, with the same effect as if it had been named herein. Such successor corporation may cause to be signed, and may issue either
in its own name or in the name of the Issuer prior to such succession any or all of the Securities issuable hereunder which theretofore shall not have been signed by the Issuer and delivered to the Trustee; and, upon the order of such successor
corporation instead of the Issuer and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Securities which previously shall have been signed and delivered by the
officers of the Issuer to the Trustee for authentication, and any Securities which such successor corporation thereafter shall cause to be signed and delivered to the Trustee for that purpose. All of the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Securities had been issued at the date of the execution hereof. 

In case of any such consolidation, merger, sale, lease or conveyance such changes in phraseology and form (but not in substance) may be made
in the Securities thereafter to be issued as may be appropriate. 
 In the event of any such sale or conveyance (other than a conveyance by
way of lease) the Issuer or any successor corporation which shall theretofore have become such in the manner described in this Article shall be discharged from all obligations and covenants under this Indenture and the Securities and may be
liquidated and dissolved. 
 Section 8.03. Opinion of Counsel to Trustee. The Trustee, subject to the provisions of Sections
5.01 and 5.02, may receive an Opinion of Counsel, prepared in accordance with Section 10.05, as conclusive evidence that any such consolidation, merger, sale, lease or conveyance, and any such assumption, and any such liquidation or
dissolution, complies with the applicable provisions of this Indenture.

 ARTICLE 9 

SATISFACTION AND DISCHARGE OF INDENTURE; UNCLAIMED MONEYS 

Section 9.01. Satisfaction and Discharge of Indenture. If at any time (a) the Issuer shall have paid or caused to be paid the
principal of and interest on all the Securities of any series Outstanding hereunder (other than Securities of such series which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.09) as and when
the same shall have become due and payable, or (b) the Issuer shall have delivered to the Trustee for cancellation all Securities of any series theretofore authenticated (other than any Securities of such series which shall have been destroyed,
lost or stolen and which shall have been replaced or paid as provided in Section 2.09) or (c) (i) all the Securities of such series not theretofore delivered to the Trustee for cancellation shall have become due and payable, or are by
their terms to become due and payable within one year or are to be called for redemption within one year under arrangements reasonably satisfactory to the Trustee for the giving of notice of redemption, and (ii) the Issuer shall have
irrevocably deposited or caused to be deposited with the Trustee as trust funds the entire amount in cash (other than moneys repaid by the Trustee or any paying agent to the Issuer in accordance with Section 9.04) or direct obligations of the
United States of America, backed by its full faith and credit (“U.S. Government Obligations”), maturing as to principal and interest in such amounts and at such times as will insure the availability of cash sufficient (in case U.S.
Government Obligations have been so deposited, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee) to pay at maturity or upon redemption all
Securities of such series (other than any Securities of such series which shall have been destroyed, lost or stolen and which shall have been replaced or paid as provided in Section 2.09) not theretofore delivered to the Trustee for
cancellation, including principal and interest due or to become due on or prior to such date of maturity as the case may be, and if, in any such case, the Issuer shall also pay or cause to be paid all other sums payable hereunder by the Issuer with
respect to Securities of such series, then this Indenture shall cease to be of further effect with respect to Securities of such series (except as to (A) rights of registration of transfer and exchange and conversion, if any, of Securities of
such series, and the Issuer’s right of optional redemption, if any, (B) substitution of mutilated, defaced, destroyed, lost or stolen Securities, (C) rights of holders to receive payments of principal thereof and interest thereon,
upon the original stated due dates therefor (but not upon acceleration) and remaining rights of the holders to receive mandatory sinking fund payments, if any, (D) the rights, obligations and immunities of the Trustee hereunder, (E) the
rights of the Securityholders of such series as beneficiaries hereof with respect to the property so deposited with the Trustee payable to all or any of them and (F) the obligations of the Issuer under Section 3.02), and the Trustee, on
demand of the Issuer accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Issuer, shall execute proper instruments acknowledging such satisfaction of and discharging this Indenture with respect to
such series; provided, that the rights of Holders of the Securities to receive amounts in respect of principal of and interest on the Securities held by them shall not be delayed longer than required by then-applicable mandatory rules or
policies of any securities exchange upon which the Securities are listed. The Issuer agrees to reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred and to compensate the Trustee for any services thereafter
reasonably and properly rendered by the Trustee in connection with this Indenture or the Securities of such series. 
 Section 9.02.
Application by Trustee of Funds Deposited for Payment of Securities. Subject to Section 9.04, all moneys deposited with the Trustee pursuant to Section 9.01 shall be held in trust and applied by it to the payment, either directly or
through any paying agent (including the Issuer acting as its own paying agent), to the Holders of the particular Securities of such series for the payment or redemption of which such moneys have been deposited with the Trustee, of all sums due and
to become due thereon for principal and interest; but such money need not be segregated from other funds except to the extent required by law. 

Section 9.03. Repayment of Moneys Held by Paying Agent. In connection with the satisfaction and discharge of this Indenture or any
defeasance under Article 12 with respect to Securities of any series, all moneys then held by any paying agent under the provisions of this Indenture with respect to such series of Securities shall, upon demand of the Issuer, be repaid to it or paid
to the Trustee and thereupon such paying agent shall be released from all further liability with respect to such moneys. 

Section 9.04. Return of Moneys Held by Trustee and Paying Agent Unclaimed for Two Years. Any moneys deposited with or paid to the
Trustee or any paying agent for the payment of the principal of or interest on any Security of any series and not applied but remaining unclaimed for two years after the date upon which such principal or interest shall have become due and payable,
shall, upon the written request of the Issuer and unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property law, be repaid to the Issuer by the Trustee for such series or such paying agent, and the
Holder of the Security of such series shall, unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property laws, thereafter look only to the Issuer for any payment which such Holder may be entitled to
collect, and all liability of the Trustee or any 

  
 28 








 
paying agent with respect to such moneys shall thereupon cease provided, however, that the Trustee or such paying agent, before being required to make any such repayment, may at the
expense of the Issuer cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in the Borough of Manhattan, The City and State of New York, notice that such
money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Issuer. 

ARTICLE 10 
 MISCELLANEOUS
PROVISIONS 
 Section 10.01. Incorporators, Stockholders, Officers and Directors of Issuer Exempt from Individual Liability. No
recourse under or upon any obligation, covenant or agreement contained in this Indenture, or in any Security, or because of any Indebtedness evidenced thereby, shall be had against any incorporator, as such or against any past, present or future
stockholder, officer or director, as such, of the Issuer or of any successor, either directly or through the Issuer or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal
or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Securities by the holders thereof and as part of the consideration for the issue of the Securities. 

Section 10.02. Provisions of Indenture for the Sole Benefit of Parties and Securityholders. Nothing in this Indenture or in the
Securities, expressed or implied, shall give or be construed to give to any person, firm or corporation, other than the parties hereto and their successors and the Holders of the Securities, any legal or equitable right, remedy or claim under this
Indenture or under any covenant or provision herein contained, all such covenants and provisions being for the sole benefit of the parties hereto and their successors and of the Holders of the Securities. 

Section 10.03. Successors and Assigns of Issuer Bound by Indenture. All the covenants, stipulations, promises and agreements in
this Indenture contained by or in behalf of the Issuer shall bind its successors and assigns, whether so expressed or not. 

Section 10.04. Notices and Demands on Issuer, Trustee and Securityholders. Any notice or demand which by any provision of this
Indenture is required or permitted to be given or served by the Trustee or by the Holders of Securities to or on the Issuer may be given or served by being deposited postage prepaid, first-class mail (except as otherwise specifically provided
herein) addressed (until another address of the Issuer is filed by the Issuer with the Trustee) to Pattern Energy Group Inc., Pier 1, Bay 3 San Francisco, CA 94111. Any notice, direction, request or demand by the Issuer or any Securityholder to or
upon the Trustee shall be deemed to have been sufficiently given or made, for all purposes if in writing and by being deposited postage prepaid, first-class mail (except as otherwise specifically provided herein) addressed to the Corporate Trust
Office, Attention: Corporate Trustee Administration Department. 
 Where this Indenture provides for notice to Holders, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder entitled thereto, at his last address as it appears in the Security register. In any case where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other 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 or irregularities in regular mail service, it shall be impracticable
to mail notice to the Issuer and Securityholders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be reasonably satisfactory to the Trustee shall be deemed to be a
sufficient giving of such notice. 
 Section 10.05. Officers’ Certificates and Opinions of Counsel; Statements to Be Contained
Therein. Upon any application or demand by the Issuer to the Trustee to take any action under any of the provisions of this Indenture, the Issuer shall furnish to the Trustee an Officers’ Certificate stating that all conditions precedent
provided for in this Indenture relating to the proposed action have been complied with and an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent have been complied with, except that in the case of any such
application or demand as to which the furnishing of such documents is specifically required by any provision of this Indenture relating to such particular application or demand, no additional certificate or opinion need be furnished. 

  
 29 








 Each certificate or opinion provided for in this Indenture and delivered to the Trustee with
respect to compliance with a condition or covenant provided for in this Indenture (other than the certificate required by Section 3.05) shall include (a) a statement that the person making such certificate or opinion has read such covenant
or condition, (b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based, (c) a statement that, in the opinion of such
person, he has made such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenant or condition has been complied with and (d) a statement as to whether or not, in the opinion
of such person, such condition or covenant has been complied with. 
 Any certificate, statement or opinion of an officer of the Issuer may
be based, insofar as it relates to legal matters, upon a certificate or opinion of or representations by counsel, unless such officer knows that the certificate or opinion or representations with respect to the matters upon which his certificate,
statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous. Any certificate, statement or opinion of counsel may be based, insofar as it relates to factual matters,
information with respect to which is in the possession of the Issuer, upon the certificate, statement or opinion of or representations by an officer of officers of the Issuer, unless such counsel knows that the certificate, statement or opinion or
representations with respect to the matters upon which his certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous. 

Any certificate, statement or opinion of an officer of the Issuer or of counsel may be based, insofar as it relates to accounting matters,
upon a certificate or opinion of or representations by an accountant or firm of accountants in the employ of the Issuer, unless such officer or counsel, as the case may be, knows that the certificate or opinion or representations with respect to the
accounting matters upon which his certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous. 

Any certificate or opinion of any independent firm of public accountants filed with the Trustee shall contain a statement that such firm is
independent. 
 Section 10.06. Payments Due on Saturdays, Sundays and Holidays. If the date of maturity of interest on or
principal of the Securities of any series or the date fixed for redemption or repayment of any such Security shall not be a Business Day, then payment of interest or principal need not be made on such date, but may be made on the next succeeding
Business Day with the same force and effect as if made on the date of maturity or the date fixed for redemption or repayment, and no interest shall accrue on the payment so deferred for the period after such date. 

Section 10.07. Conflict of Any Provision of Indenture with Trust Indenture Act of 1939. If and to the extent that any provision of
this Indenture limits, qualifies or conflicts with the duties imposed by or with another provision (an “incorporated provision”) included in this Indenture by operation of Sections 310 to 318, inclusive, of the Trust Indenture Act
of 1939, such imposed duties or incorporated provision shall control. 
 Section 10.08. New York Law to Govern. This Indenture
and each Security shall be deemed to be a contract under the laws of the State of New York, and for all purposes shall be construed in accordance with the laws of such State, except as may otherwise be required by mandatory provisions of law. 

Section 10.09. Counterparts. This Indenture may be executed in any number of counterparts, each of which shall be an original; but
such counterparts shall together constitute but one and the same instrument. 
 Section 10.10. Effect of Headings. The Article
and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. 

Section 10.11. Separability Clause. In case any provision of this Indenture or in the Securities shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

ARTICLE 11 
 REDEMPTION OF
SECURITIES AND SINKING FUNDS 
 Section 11.01. Applicability of Article. The provisions of this Article shall be applicable to
the Securities of any series which are redeemable before their maturity or to any sinking fund for the retirement of Securities of a series except as otherwise specified as contemplated by Section 2.03 for Securities of such series. 

  
 30 








 Section 11.02. Notice of Redemption; Partial Redemptions. Notice of redemption to the
Holders of Securities of any series to be redeemed as a whole or in part at the option of the Issuer shall be given by mailing notice of such redemption by first class mail, postage prepaid, at least 30 days and not more than 60 days prior to the
date fixed for redemption to such Holders of Securities of such series at their last addresses as they shall appear upon the registry books. Any notice which is mailed in the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the Holder receives the notice. Failure to give notice by mail, or any defect in the notice to the Holder of any Security of a series designated for redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Security of such series. 
 The notice of redemption to each such Holder shall specify the
principal amount of each Security of such series held by such Holder to be redeemed, the date fixed for redemption, the redemption price, the place or places of payment, that payment will be made upon presentation and surrender of such Securities,
that such redemption is pursuant to the mandatory or optional sinking fund, or both, if such be the case, that interest accrued to the date fixed for redemption will be paid as specified in such notice and that on and after said date interest
thereon or on the portions thereof to be redeemed will cease to accrue. In case any Security of a series is to be redeemed in part only the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state
that on and after the date fixed for redemption, upon surrender of such Security, a new Security or Securities of such series in principal amount equal to the unredeemed portion thereof will be issued. 

The notice of redemption of Securities of any series to be redeemed at the option of the Issuer shall be given by the Issuer or, at the
Issuer’s request, by the Trustee in the name and at the expense of the Issuer. 
 On or prior to the redemption date specified in the
notice of redemption given as provided in this Section, the Issuer will deposit with the Trustee or with one or more paying agents (or, if the Issuer is acting as its own paying agent, set aside, segregate and hold in trust as provided in
Section 3.04) an amount of money sufficient to redeem on the redemption date all the Securities of such series so called for redemption at the appropriate redemption price, together with accrued interest to the date fixed for redemption. If
less than all the Outstanding Securities of a series are to be redeemed, the Issuer will deliver to the Trustee at least 70 days prior to the date on which notice of redemption is to be issued an Officers’ Certificate stating the aggregate
principal amount of Securities to be redeemed. 
 If less than all the Securities of a series are to be redeemed, the Trustee shall select,
in such manner as it shall deem appropriate and fair, Securities of such Series to be redeemed in whole or in part. Securities may be redeemed in part in multiples equal to the minimum authorized denomination for Securities of such series or any
multiple thereof. The Trustee shall promptly notify the Issuer in writing of the Securities of such series selected for redemption and, in the case of any Securities of such series selected for partial redemption, the principal amount thereof to be
redeemed. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities of any series shall relate, in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be redeemed. 
 Section 11.03. Payment of Securities Called
for Redemption. If notice of redemption has been given as above provided, the Securities or portions of Securities specified in such notice shall become due and payable on the date and at the place stated in such notice at the applicable
redemption price, together with interest accrued to the date fixed for redemption, and on and after said date (unless the Issuer shall default in the payment of such Securities at the redemption price, together with interest accrued to said date)
interest on the Securities or portions of Securities so called for redemption shall cease to accrue and, except as provided in Sections 5.05 and 9.04, such Securities shall cease from and after the date fixed for redemption to be entitled to any
benefit or security under this Indenture, and the Holders thereof shall have no right in respect of such Securities except the right to receive the redemption price thereof and unpaid interest to the date fixed for redemption. On presentation and
surrender of such Securities at a place of payment specified in said notice, said Securities or the specified portions thereof shall be paid and redeemed by the Issuer at the applicable redemption price, together with interest accrued thereon to the
date fixed for redemption; provided that any semiannual payment of interest becoming due on or prior to the date fixed for redemption shall be payable to the Holders of such Securities registered as such on the relevant record date subject to
the terms and provisions of Section 2.04 hereof. 
 If any Security called for redemption shall not be so paid upon surrender thereof
for redemption, the principal shall, until paid or duly provided for, bear interest from the date fixed for redemption at the rate of interest or Yield to Maturity (in the case of an Original Issue Discount Security) borne by the Security. 

Upon presentation of any Security redeemed in part only, the Issuer shall execute and the Trustee shall authenticate and deliver to or on the
order of the Holder thereof, at the expense of the Issuer, a new Security or Securities of such series, of authorized denominations, in principal amount equal to the unredeemed portion of the Security so presented. 

Section 11.04. Exclusion of Certain Securities from Eligibility for Selection for Redemption. Securities shall be excluded from
eligibility for selection for redemption if they are identified by registration and certificate number in a written statement signed by an 

  
 31 








 
authorized officer of the Issuer and delivered to the Trustee at least 40 days prior to the last date on which notice of redemption may be given as being owned of record and beneficially by, and
not pledged or hypothecated by either (a) the Issuer or (b) an entity specifically identified in such written statement directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer. 

Section 11.05. Mandatory and Optional Sinking Funds. The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series 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 Securities of any series is herein referred to as an
“optional sinking fund payment”. The date on which a sinking fund payment is to be made is herein referred to as the “sinking fund payment date”. 

In lieu of making all or any part of any mandatory sinking fund payment with respect to any series of Securities in cash, the Issuer may at
its option (a) deliver to the Trustee Securities of such series theretofore purchased or otherwise acquired (except upon redemption pursuant to the mandatory sinking fund) by the Issuer or receive credit for Securities of such series (not
previously so credited) theretofore purchased or otherwise acquired (except as aforesaid) by the Issuer and delivered to the Trustee for cancellation pursuant to Section 2.10, (b) receive credit for optional sinking fund payments (not
previously so credited) made pursuant to this Section, (c) receive credit for Securities of such series (not previously so credited) redeemed by the Issuer through any optional redemption provision contained in the terms of such series or
(d) which have been converted into Common Stock or otherwise acquired by the Issuer pursuant to the terms of such Securities. Securities so delivered or credited shall be received or credited by the Trustee at the sinking fund redemption price
specified in such Securities. 
 On or before the sixtieth day next preceding each sinking fund payment date for any series, the Issuer will
deliver to the Trustee a written statement (which need not contain the statements required by Section 10.05) signed by an authorized officer of the Issuer (a) specifying the portion of the mandatory sinking fund payment to be satisfied by
payment of cash and the portion to be satisfied by credit of Securities of such series, (b) stating that none of the Securities of such series has theretofore been so credited, (c) stating that no defaults in the payment of interest or
Events of Default with respect to such series have occurred (which have not been waived or cured) and are continuing and (d) stating whether or not the Issuer intends to exercise its right to make an optional sinking fund payment with respect
to such series and, if so, specifying the amount of such optional sinking fund payment which the Issuer intends to pay on or before the next succeeding sinking fund payment date. Any Securities of such series to be credited and required to be
delivered to the Trustee in order for the Issuer to be entitled to credit therefor as aforesaid which have not theretofore been delivered to the Trustee shall be delivered for cancellation pursuant to Section 2.10 to the Trustee with such
written statement (or reasonably promptly thereafter if acceptable to the Trustee). Such written statement shall be irrevocable and upon its receipt by the Trustee the Issuer shall become unconditionally obligated to make all the cash payments or
payments therein referred to, if any, on or before the next succeeding sinking fund payment date. Failure of the Issuer, on or before any such sixtieth day, to deliver such written statement and Securities specified in this paragraph, if any, shall
not constitute a default but shall constitute, on and as of such date, the irrevocable election of the Issuer (i) that the mandatory sinking fund payment for such series due on the next succeeding sinking fund payment date shall be paid
entirely in cash without the option to deliver or credit Securities of such series in respect thereof and (ii) that the Issuer will make no optional sinking fund payment with respect to such series as provided in this Section. 

If the sinking fund payment or payments (mandatory or optional or both) to be made in cash on the next succeeding sinking fund payment date
plus any unused balance of any preceding sinking fund payments made in cash shall exceed $50,000 (or a lesser sum if the Issuer shall so request) with respect to the Securities of any particular series, such cash shall be applied on the next
succeeding sinking fund payment date to the redemption of Securities of such series at the sinking fund redemption price together with accrued interest to the date fixed for redemption. If such amount shall be $50,000 or less and the Issuer makes no
such request then it shall be carried over until a sum in excess of $50,000 is available. The Trustee shall select, in the manner provided in Section 11.02, for redemption on such sinking fund payment date a sufficient principal amount of
Securities of such series to absorb said cash, as nearly as may be, and shall (if requested in writing by the Issuer) inform the Issuer of the serial numbers of the Securities of such series (or portions thereof) so selected. The Trustee, in the
name and at the expense of the Issuer (or the Issuer, if it shall so request the Trustee in writing) shall cause notice of redemption of the Securities of such series to be given in substantially the manner provided in Section 11.02 (and with
the effect provided in Section 11.03) for the redemption of Securities of such series in part at the option of the Issuer. The amount of any sinking fund payments not so applied or allocated to the redemption of Securities of such series shall
be added to the next cash sinking fund payment for such series and, together with such payment, shall be applied in accordance with the provisions of this Section. Any and all sinking fund moneys held on the stated maturity date of the Securities of
any particular series (or earlier, if such maturity is accelerated), which are not held for the payment or redemption of particular Securities of such series shall be applied, together with other moneys, if necessary, sufficient for the purpose, to
the payment of the principal of, and interest on, the Securities of such series at maturity. 

  
 32 








 On or prior to each sinking fund payment date, the Issuer shall pay to the Trustee in cash or
shall otherwise provide for the payment of all interest accrued to the date fixed for redemption on Securities to be redeemed on such sinking fund payment date. 

The Trustee shall not redeem or cause to be redeemed any Securities of a series with sinking fund moneys or mail any notice of redemption of
Securities for such series by operation of the sinking fund during the continuance of a default in payment of interest on such Securities or of any Event of Default except that, where the mailing of notice of redemption of any Securities shall
theretofore have been made, the Trustee shall redeem or cause to be redeemed such Securities, provided that it shall have received from the Issuer a sum sufficient for such redemption. Except as aforesaid, any moneys in the sinking fund for
such series at the time when any such default or Event of Default shall occur, and any moneys thereafter paid into the sinking fund, shall, during the continuance of such default or Event of Default, be deemed to have been collected under Article 4
and held for the payment of all such Securities. In case such Event of Default shall have been waived as provided in Section 4.10 or the default cured on or before the sixtieth day preceding the sinking fund payment date in any year, such
moneys shall thereafter be applied on the next succeeding sinking fund payment date in accordance with this Section to the redemption of such Securities. 

ARTICLE 12 
 DEFEASANCE 

Section 12.01. Issuer’s Option to Effect Defeasance. The Issuer may at its option, by Board Resolution, at any time, elect to
defease the Issuer’s obligations under the Outstanding Securities of any series and this Indenture in accordance with either Section 12.02 or Section 12.03 upon compliance with the conditions set forth below in this Article 12.
Notwithstanding any such election, the terms of the Securities of such series shall remain in full force and effect. 

Section 12.02. Defeasances and Discharge. Upon the Issuer’s exercise of the option set forth in Section 12.01 applicable
to this Section, and after the expiration of the 90-day (or other) period referred to in clause (f)(ii) of Section 12.04, the Issuer shall be deemed to have been discharged from its obligations with respect to the Outstanding Securities of such
series on the date the conditions set forth below are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that the Issuer shall be deemed to have paid and discharged the entire indebtedness represented by
the Outstanding Securities of such series and to have satisfied all its other obligations under the Securities of such series and this Indenture insofar as the Securities of such series are concerned (and the Trustee, upon an Issuer Order and at the
expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (a) the rights of holders of Outstanding Securities of such series
to receive, solely from the trust fund described in Section 12.04 and as more fully set forth in such Section, payments in respect of the principal of and interest on the Securities of such series when such payments are due, (b) the
Issuer’s obligations with respect to such Securities of such series under Sections 2.08, 2.09 and 3.02, (c) the rights, powers, trusts, duties, and immunities of the Trustee hereunder, including but not limited to Article 5, (d) the
Issuer’s right of optional redemption, if any, (e) the rights of Holders to receive mandatory sinking fund payments, if any, and (f) this Article 12. Subject to compliance with this Article 12, the Issuer may exercise its option
under this Section 12.02 notwithstanding the prior exercise of its option under Section 12.03 with respect to the Securities of such series. 

Section 12.03. Covenant Defeasance. Upon the Issuer’s exercise of the option set forth in Section 12.01 applicable to
this Section, and after the expiration of the 90-day (or other) period referred to in clause (f)(ii) of Section 12.04, the Issuer shall be released, on and after the date the conditions set forth below are satisfied, from its obligations with
respect to the Outstanding Securities of any series under any covenants established with respect to such series pursuant to Section 2.02(n) (hereinafter, “covenant defeasance”). For this purpose, such covenant defeasance means
that, with respect to the Outstanding Securities of such series, the Issuer may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such Section, 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, and such omission to comply shall not constitute a default or Event of Default under
Section 4.01(d), but, except as specified above, the remainder of this Indenture and the Securities of such series shall be unaffected thereby. 

Section 12.04. Conditions to Defeasance. The following shall be the conditions to application of either Section 12.02 or
Section 12.03 to the Outstanding Securities of any series. 
 (a) The Issuer shall irrevocably have deposited or caused to be deposited
with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the holders of Securities of such series (i) money in an amount, or
(ii) U.S. Government Obligations which through the scheduled payment of principal and interest, if any, 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 (iii) a combination thereof, sufficient, in each case, in the opinion of a nationally recognized firm of 

  
 33 








 
independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee to pay and discharge the
principal of and interest, if any, on the Outstanding Securities of such series on the stated maturity of such principal or interest or earlier date of redemption. 

(b) No Event of Default or event which after notice or lapse of time or both would become an Event of Default with respect to the Securities
of such series shall have occurred and be continuing on the date of such deposit. 
 (c) Such defeasance or covenant defeasance shall not
cause the Trustee for the Securities of such series to have a conflicting interest as defined in Section 310(b) of the Trust Indenture Act of 1939 with respect to any Securities of the Issuer. 

(d) Such defeasance or covenant defeasance shall be permitted by, and shall not result in breach or violation of, or constitute a default
under, this Indenture or any other agreement or instrument to which the Issuer is a party or by which it is bound. 
 (e) Such defeasance or
covenant defeasance shall not cause any Securities of such series then listed on any registered national securities exchange under the Securities Exchange Act of 1934, as amended, to be delisted. 

(f) In the case of an election under Section 12.02, the Issuer shall have delivered to the Trustee an Opinion of Counsel stating that the
Issuer has received from, or there has been published by, the Internal Revenue Service a ruling to the effect that, and based thereon such opinion shall confirm that, (i) the Holders of the Outstanding Securities of such series will not
recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had
not occurred, and (ii) that after the passage of 90 days (or such other period of time as then required by the non-insider preference provisions of any applicable federal bankruptcy laws) following the deposit, the trust funds will not be
subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally, and (iii) that there would not occur any violation of the Investment Company Act of 1940, as amended, on
the part of the Issuer, the trust funds representing such deposit or the Trustee as a result of such deposit and the related exercise of the Issuer’s election under this Article 12. 

(g) In the case of an election under Section 12.03, the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect
that the Holders of the Outstanding Securities of such series will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax on the same amounts, in the same
manner and at the same times as would have been the case if such covenant defeasance had not occurred. Such Opinion shall also cover the matters referred to in clauses (ii) and (iii) of Section 12.04(f). 

(h) The Issuer shall have delivered to the Trustee an irrevocable Issuer Order to apply the monies so deposited towards payment of all
indebtedness on the Securities of such series at their stated maturity or earlier date of redemption, and an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to either the
defeasance under Section 12.02 or the covenant defeasance under Section 12.03 (as the case may be) have been complied with. 

Section 12.05. Deposited Money and U.S. Government Obligations to Be Held in Trust; Reinstatement; Miscellaneous. Subject to the
provisions of Section 9.04, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee pursuant to Section 12.04 in respect of the Outstanding Securities of any series shall be held in trust and
applied by the Trustee, in accordance with the provisions of the Securities of such series and this Indenture, to the payment, either directly or through any paying agent (including the Issuer acting as its own paying agent), as the Trustee may
determine, to the holders of Securities of such series, of all sums due and to become due thereon in respect of principal and interest, if any, but such money need not be segregated from other funds except to the extent required by law. 

The Issuer 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 9.01 or 12.04 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 the Outstanding Securities of such
series. 
 If the Trustee is unable to apply any money or U.S. Government Obligations in accordance with Section 9.01 or 12.04 by
reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s obligations under this Indenture and the Securities of
such series shall be revived and reinstated as though no deposit had occurred pursuant to Section 9.01 or 12.04; provided that if the Issuer has made any payment of principal of or interest on any Securities of such series because of the
reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Securities of such series to receive such payment from the money or U.S. Government Obligations held by the Trustee.

 ARTICLE 13 

SUBORDINATION OF SECURITIES 

Section 13.01. Securities Subordinate to Senior Indebtedness. The Issuer covenants and agrees, and each Holder of a Security, by
acceptance thereof, whether upon original issue or upon transfer or assignment, likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth, the payment of the principal of and interest on each and all of the
Securities is hereby expressly made subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness. 

Section 13.02. Payment Over of Proceeds Upon Dissolution, Etc. of the Issuer. In the event of any insolvency or bankruptcy case or
proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to the Issuer or to its creditors, as such, or to its property, and in the event of any voluntary liquidation,
dissolution or other winding up of the Issuer, whether or not involving insolvency or bankruptcy, then the holders of Senior Indebtedness shall be entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior
Indebtedness before the Holders of the Securities are entitled to receive any payment on account of principal of or interest on the Securities, and to that end (but subject to the power of a court of competent jurisdiction to make other equitable
provision reflecting the rights conferred by the provisions of this Article upon the Senior Indebtedness and the holders thereof with respect to the Securities and the Holders thereof by a lawful plan of reorganization under applicable bankruptcy
law) the holders of Senior Indebtedness shall be entitled to receive any payment or distribution of any kind or character, whether in cash, property or securities, which may be payable or deliverable in any such case or proceeding in respect of the
Securities, except securities of the Issuer which are subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness then outstanding. 

In the event that, notwithstanding the foregoing, the Trustee or the Holder of any Security shall have received any payment or distribution of
any kind or character, whether in cash, property or securities (other than as aforesaid), before all Senior Indebtedness is paid in full or payment thereof provided for, and if such fact shall then have been made known to the Trustee or, as the case
may be, such Holder, then and in such event such payment or distribution shall be paid over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee, custodian, agent or other Person making payment or distribution of assets
or securities of the Issuer for application to the payment of all Senior Indebtedness remaining unpaid, to the extent necessary to pay all Senior Indebtedness in full, after giving effect to any concurrent payment or distribution to or for the
holders Senior Indebtedness. 
 In the event that any Securities are declared due and payable before their final maturity because of the
occurrence of an Event of Default (under circumstances when the provisions of the foregoing paragraph shall not be applicable), the holders of the Senior Indebtedness outstanding at the time such Securities become due and payable because of such
occurrence of an Event of Default shall be entitled to receive payment in full of all amounts due or to become due or in respect of all Senior Indebtedness before the Holders of the Securities are entitled to receive any payment on account of the
principal of or interest on the Securities. 
 The consolidation of the Issuer with, or the merger of the Issuer into, another corporation
or the liquidation or dissolution of the Issuer following the conveyance or transfer of its properties and assets substantially as an entirety to another corporation upon the terms and conditions set forth in Article Eight shall not be deemed a
dissolution, winding up, liquidation or reorganization for the purposes of this Section if such other corporation shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions set forth in Article Eight. 

Nothing in this Article shall apply to claims of, or payments to, the Trustee under or pursuant to Section 5.06. 

Section 13.03. No Payment When Senior Indebtedness in Default in Payment. (a) In the event and during the continuation of any
default in the payment of principal of or interest on any Senior Indebtedness beyond any applicable period of grace, unless and until such default in payment shall have been cured or waived or shall have ceased to exist, or (b) in the event any
judicial proceeding shall be pending with respect to any such default in payment, then no payment of principal of or interest on the Securities shall be made by the Issuer; provided, however, that nothing in this Section shall prevent the
satisfaction of any sinking fund payment in accordance with Article Eleven by means of Securities redeemed or acquired prior to such default in payment or by means of conversion Securities. 

Section 13.04. Payment Permitted If No Default. Nothing contained in this Article or elsewhere in this Indenture or in any of the
Securities shall prevent (a) the Issuer, at any time except during the pendency of any case or proceeding, or any dissolution or other winding up referred to in Section 13.02 or under the other conditions described in Section 13.02 or
the conditions described in Section 13.03 from making payments at any time of principal of or interest on the Securities, or (b) the application by the Trustee of any money deposited with it hereunder to the payment of or on account of the
principal of or interest on the Securities if, at the time of such application, the Trustee did not have knowledge that such payment would have been prohibited by the provisions of this Article. 

  
 35 








 Section 13.05. Subrogation to Rights of Holders of Senior Indebtedness. Subject to
the payment in full of all Senior Indebtedness, the Holders of the Securities shall be subrogated (to the extent of the payments or distributions made to the holders of such Senior Indebtedness pursuant to the provisions of this Article) to the
rights of the holders of such Senior Indebtedness to receive payments or distributions from the Issuer applicable to the Senior Indebtedness until the principal of (and premium, if any) and interest on the Securities shall be paid in full. For
purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness to which the Holders of the Securities or the Trustee would be entitled except for the provisions of this Article, and no payments over pursuant to
the provisions of this Article to the holders of Senior Indebtedness by Holders of the Securities or the Trustee, shall, as between the Issuer, its creditors other than holders of Senior Indebtedness, and the Holders of the Securities, be deemed to
be a payment or distribution by the Issuer to or on account of the Senior Indebtedness. 
 Section 13.06. Provisions Solely to
Define Relative Rights. The provisions of this Article are and are intended solely for the purpose of defining the relative rights of the Holders of the Securities, on the one hand, and the holders of Senior Indebtedness, on the other hand.
Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or shall impair, as between the Issuer and the Holders of the Securities, the obligation of the Issuer, which is absolute and unconditional, to pay
to the Holders of the Securities the principal of and interest on the Securities as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights against the Issuer of the
Holders of the Securities and creditors of the Issuer other than the holders of Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the rights, if any, under this Article of the holders of Senior Indebtedness to receive cash, property or securities of the Issuer otherwise payable or deliverable to the Trustee or such
Holder. 
 Section 13.07. Trustee to Effectuate Subordination. Each Holder of a Security by acceptance thereof, whether upon
original issue or upon transfer or assignment, authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article and appoints the Trustee his
attorney-in-fact for any and all such purposes. 
 Section 13.08. No Waiver of Subordination Provisions. No right of any present
or future holder of any Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Issuer or by any act or failure to act, in good faith, by
any such holder, or by any noncompliance by the Issuer with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. 

Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to the Holders of the Securities, without incurring responsibility to the Holders of the Securities and without impairing or releasing the subordination provided in this Article or the obligations of the
Holders of the Securities to the holders of the Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms of payment of, or renew or alter, Senior Indebtedness, or otherwise amend or supplement in any
manner Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (iii) release any Person liable in any manner for the collection of Senior Indebtedness; and (iv) exercise or refrain from exercising any rights against the Issuer and any other Person. 

Section 13.09. Notice to Trustee. The Issuer shall give prompt written notice to the Trustee of any fact known to the Issuer which
would prohibit the making of any payment of money to or by the Trustee in respect of the Securities pursuant to the provisions of this Article. Notwithstanding the provisions of this Article or any other provision of this Indenture, the Trustee
shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment to or by the Trustee in respect of the Securities pursuant to the provisions of this Article, unless and until a responsible officer of
the Trustee shall have received at its Corporate Trust Office written notice thereof from the Issuer or a holder or holders of Senior Indebtedness or from any trustee therefor; and, prior to the receipt of any such written notice, the Trustee,
subject to the provisions of Section 5.01, shall be entitled in all respects to assume that no such facts exist. 
 Subject to the
provisions of Section 5.01, the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself or herself to be a holder of Senior Indebtedness (or a trustee on behalf of such holder) to establish
that such notice has been given by a holder of Senior Indebtedness or a trustee on behalf of any such holder. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a
holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held
by such Person, the extent to which such Person is 

  
 36 








 
entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article, and if such evidence is not furnished, the Trustee may defer
any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 
 Section 13.10.
Reliance on Certificate of Liquidating Agent. Upon any payment or distribution referred to in this Article, the Trustee, subject to the provisions of Section 5.01, and the Holders of the Securities shall be entitled to rely upon any order
or decree entered by any court of competent jurisdiction in which such insolvency, bankruptcy, receivership, liquidation reorganization, dissolution, winding up or similar case or proceeding is pending, or a certificate of the trustee in bankruptcy,
liquidating trustee, custodian, receiver, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders of Securities, for the purpose of ascertaining the Persons
entitled to participate in such distribution, the holders of the Senior Indebtedness and other indebtedness of the Issuer, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto
or to this Article. 
 Section 13.11. Trustee Not Fiduciary for Holders of Senior Indebtedness. The Trustee shall not be deemed
to owe any fiduciary duty to the holders of Senior Indebtedness. The Trustee’s duties to holders of Senior Indebtedness are limited to those specifically set forth in this Indenture and no implied covenants or obligations shall be read into
this Indenture against the Trustee. The Trustee shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Issuer or to any other Person cash, property or securities to
which any holders of Senior Indebtedness shall be entitled by virtue of this Article or otherwise. 
 ARTICLE 14 

CONVERSION OF SECURITIES 

Section 14.01. Applicability; Conversion Privilege and Conversion Price. Securities of any series which are convertible into
Common Stock shall be convertible in accordance with their terms and (except as otherwise specified as contemplated by Section 2.03 for Securities of any series) in accordance with this Article. 

Subject to and upon compliance with the provisions of this Article 14, at the option of the Holder thereof, any Security or any portion of the
principal amount thereof which is $1,000 or an integral multiple of $1,000 may be converted at the principal amount thereof, (or, with respect to Original Issue Discount Securities, at the amount determined pursuant to Section 2.03), or of such
portion thereof, into fully paid and nonassessable shares (calculated as to each conversion to the nearest one-hundredth of a share) of Common Stock, at the Conversion Price, determined as hereinafter provided, in effect at the time of conversion.
Such conversion right shall expire at the close of business on the date specified for Securities of such Series. In case a Security or portion thereof is called for redemption, such conversion right in respect of the Security or portion so called
shall expire at the close of business on the date fixed for redemption, unless the Issuer defaults in making the payment due upon redemption. 

The price at which shares of Common Stock shall be delivered upon conversion (herein called the “Conversion Price”) shall be
the price specified in relation to Securities of such series pursuant to Section 2.03. The Conversion Price shall be adjusted in certain instances as provided in paragraphs (a), (b), (c), (d) and (g) of Section 14.04. 

Section 14.02. Exercise of Conversion Privilege. In order to exercise the conversion privilege, the Holder of any Security to be
converted shall surrender such Security, together with the conversion notice duly executed, at any office or agency of the Issuer maintained for that purpose pursuant to Section 3.02, accompanied by written notice to the Issuer at such office
or agency that the Holder elects to convert such Security or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted. Securities or portions thereof surrendered for conversion during the period from
the close of business on any regular record date next preceding any interest payment date to the opening of business on such interest payment date shall (unless such Securities or portions thereof have been called for redemption on a redemption date
within such period) be accompanied by payment to the Issuer or its order, in New York Clearing House funds or other funds acceptable to the Issuer, of an amount equal to the interest payable on such interest payment date on the principal amount of
Securities or portions thereof being surrendered for conversion. No payment or adjustment shall be made upon any conversion on account of any interest accrued on the Securities surrendered for conversion or, except as provided in Section 14.04,
on account of any dividends on the Common Stock issued upon conversion. 
 Securities shall be deemed to have been converted immediately
prior to the close of business on the day of surrender of such Securities for conversion in accordance with the foregoing provisions, and at such time the rights of the Holders of such Securities as Holders shall cease, and the Person or Persons
entitled to receive the Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such Common Stock at such time. As promptly as practicable on or after the conversion date, the Issuer shall issue and
shall deliver at such office or agency a certificate or certificates for the number of full shares of Common Stock issuable upon conversion, together with payment in lieu of any fraction of a share, as provided in Section 14.03. 

  
 37 








 In the case of any Security which is converted in part only, upon such conversion the Issuer
shall execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Issuer, a new Security or Securities of authorized denominations in aggregate principal amount equal to the unconverted portion of the
principal amount of such Security. 
 Section 14.03. Fractions of Shares. No fractional shares of Common Stock shall be issued
upon conversion of Securities. 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 thereof shall be computed on the basis of the aggregate
principal amount of the Securities (or specified portions thereof) so surrendered. Instead of any fractional share of Common Stock which would otherwise be issuable upon conversion of any Security or Securities (or specified portions thereof), the
Issuer shall pay a cash adjustment in respect of such fraction in an amount equal to the same fraction of the market price (determined as provided in the last sentence of paragraph (f) of Section 14.04) at the close of business on the day
of conversion. 
 Section 14.04. Adjustment of Conversion Price. (a) In case the Issuer shall pay or make a dividend or
other distribution on any class of capital stock of the Issuer in Common Stock, the Conversion Price in effect at the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such dividend or
other distribution shall be reduced by multiplying such Conversion Price by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination and the
denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such reduction to become effective immediately after the opening of business on the day following the date fixed
for such determination. For the purposes of this paragraph (a), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Issuer but shall include shares issuable in respect of scrip
certificates issued in lieu of fractions of shares of Common Stock. The Issuer will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Issuer. 

(b) In case the Issuer shall issue rights or warrants to all holders of its Common Stock entitling them to subscribe for or purchase shares of
Common Stock at a price per share less than the market price (determined as provided in paragraph (f) of this Section) of the Common Stock on the date fixed for the determination of stockholders entitled to receive such rights or warrants, the
Conversion Price in effect at the opening of business on the day following the date fixed for such determination shall be reduced by multiplying such Conversion Price by a fraction of which the numerator shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock which the aggregate of the offering price of the total number of shares of Common Stock so offered for subscription or purchase
would purchase at such market price and the denominator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock so offered for subscription
or purchase, such reduction to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purposes of this paragraph (b), the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Issuer but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Issuer will not issue any rights or warrants in
respect of shares of Common Stock held in the treasury of the Issuer. 
 (c) In case outstanding shares of Common Stock shall be subdivided
into a greater number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and, conversely, in case
outstanding shares of Common Stock shall each be combined into a smaller number of shares of Common Stock, the Conversion Price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be
proportionately increased, such reduction or increase, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. 

(d) In case the Issuer shall, by dividend or otherwise, distribute to all holders of its Common Stock evidences of its indebtedness or assets
(including securities, but excluding any rights or warrants referred to in paragraph (b) of this Section, any dividend or distribution paid in cash out of the retained earnings of the Issuer and any dividend or distribution referred to in
paragraph (a) of this Section), the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the date fixed for the
determination of stockholders entitled to receive such distribution by a fraction of which the numerator shall be the market price per share (determined as provided in paragraph (f) of this Section) of the Common Stock on the date fixed for
such determination, reduced by the then fair market value (as determined by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution filed with the Trustee) of the portion of the assets or evidence of
indebtedness so distributed applicable to one share of Common Stock and the denominator shall be such market price per share of the Common Stock, such adjustment to become effective immediately prior to the opening of business on the day following
the date fixed for the determination of stockholders entitled to receive such distribution. 

  
 38 








 (e) The reclassification of Common Stock into securities including other than Common Stock (other
than any reclassification upon a consolidation or merger to which Section 14.11 applies) shall be deemed to involve (a) a distribution of such securities other than Common Stock to all holders of Common Stock (and the effective date of
such reclassification shall be deemed to be “the date fixed for the determination of stockholders entitled to receive such distribution” and “the date fixed for such determination”) within the meaning of paragraph (d) of
this Section, and (b) a subdivision or combination, as the case may be, of the number of shares of Common Stock outstanding immediately prior to such reclassification into the number of shares of Common Stock outstanding immediately thereafter
(and the effective date of such reclassification shall be deemed to be “the day upon which such subdivision becomes effective” or “the day upon which such combination becomes effective”, as the case may be, and “the day upon
which such subdivision or combination becomes effective” within the meaning of paragraph (c) of this Section). 
 (f) For the
purpose of any computation under paragraphs (b) and (d) of this Section, the market price on any date shall be deemed to be the average of the daily market prices for the ten consecutive Business Days selected by the Issuer commencing not
less than ten nor more than 80 Business Days before the day in question. The closing price for each day shall be the last reported sales price regular way on the composite tape or, in case no such reported sale takes place on such day, the average
of the reported closing bid and asked prices regular way, in either case on the New York Stock Exchange or, if the Common Stock is not listed or admitted to trading on such Exchange, on the principal national securities exchange on which the Common
Stock is listed or admitted to trading or, if not listed or admitted to trading on any national securities exchange, the average of the closing bid and asked prices as furnished by any New York Stock Exchange member firm selected from time to time
by the Issuer for that purpose. 
 (g) The Issuer may make such reductions in the Conversion Price, in addition to those required by
paragraphs (a), (b), (c) and (d) of this Section, as it considers to be advisable in order that any event treated for Federal income tax purposes as a dividend of stock or stock rights shall not be taxable to the recipients. 

Section 14.05. Notice of Adjustments of Conversion Price. Whenever the Conversion Price is adjusted as herein provided: 

(a) the Issuer shall compute the adjusted Conversion Price in accordance with Section 14.04 and shall prepare a certificate signed by the
Treasurer or an Assistant Treasurer, the Controller or an Assistant Controller of the Issuer 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 with the Trustee and at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 3.02; and 

(b) a notice stating that the Conversion Price has been adjusted and setting forth the adjusted Conversion Price shall forthwith be required,
and as soon as practicable after it is required, such notice shall be prepared by the Issuer, filed with the Trustee and mailed by the Issuer to all Holders at their last addresses as they shall appear in the Security register. 

Section 14.06. Notice of Certain Corporate Action. In case: 

(a) the Issuer shall declare a dividend (or any other distribution) on Common Stock payable otherwise than in cash out of its retained
earnings; or 
 (b) the Issuer shall authorize the granting to the holders of Common Stock of rights or warrants to subscribe for or
purchase any shares of capital stock of any class or of any other rights; or 
 (c) of any reclassification of the Common Stock (other than
a subdivision or combination of its outstanding shares of Common Stock), or of any consolidation or merger to which the Issuer is a party and for which approval of any stockholders of the Issuer is required, or of the sale or transfer of all or
substantially all of the assets of the Issuer; or 
 (d) of the voluntary or involuntary dissolution, liquidation or winding up of the
Issuer; then the Issuer shall cause to be filed with the Trustee and at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 3.02, 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 ten days in any case specified in clause (a) or (b) above) prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on
which a record is to be taken for the purpose of such dividend, distribution, rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights or
warrants are to be determined, or (y) the date on which such reclassification, 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 

  
 39 








 
securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up. The failure to give notice required by
this Section or any defect therein shall not affect the legality or validity of any dividend, distribution, rights, warrants, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up, or the vote on any such
action. 
 Section 14.07. Issuer to Reserve Common Stock. The Issuer shall at all times reserve and keep available, free from
pre-emptive 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 then issuable upon the conversion of all outstanding Securities. 

Section 14.08. Taxes on Conversions. The Issuer will pay any and all transfer taxes that may be payable in respect of the issue or
delivery of shares of Common Stock on conversion of Securities pursuant thereto. The Issuer 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 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 Issuer the amount of any such tax, or has
established to the satisfaction of the Issuer that such tax has been paid. 
 Section 14.09. Covenant as to Common Stock. The
Issuer covenants that all shares of Common Stock which may be issued upon conversion of Securities will upon issue be fully paid and nonassessable. 

Section 14.10. Cancellation of Converted Securities. All Securities delivered for conversion shall be delivered to the Trustee for
cancellation and the Trustee shall dispose of the same as provided in Section 2.10. 
 Section 14.11. Provisions in Case of
Consolidation, Merger or Sale of Assets. In case of any consolidation of the Issuer with, or merger of the Issuer into, any other corporation, any merger of another corporation into the Issuer (other than a merger which does not result in any
reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock of the Issuer) or any sale or transfer of all or substantially all of the assets of the Issuer, the corporation 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 then outstanding shall have the right thereafter, during the period such
Security shall be convertible as specified in Section 14.01, to convert such Security only into the kind and amount of securities, cash and other property receivable upon such consolidation, merger, sale or transfer by a holder of the number of
shares of Common Stock of the Issuer into which such Security might have been converted immediately prior to such consolidation, merger, sale or transfer, assuming such holder of Common Stock of the Issuer (a) is not a corporation with which
the Issuer consolidated or into which the Issuer merged or which merged into the Issuer or to which such sale or transfer was made, as the case may be (“constituent corporation”), or an affiliate of a constituent corporation and
(b) 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, sale or transfer (provided that if the kind or amount of securities, cash and
other property receivable upon such consolidation, merger, sale or transfer is not the same for each share of Common Stock of the Issuer held immediately prior to such consolidation, merger, sale or transfer by others than a constituent corporation
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 the kind and amount of securities, cash and other property receivable
upon such consolidation, merger, sale or transfer by 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. The above provisions of this Section shall similarly apply to
successive consolidations, mergers, sales or transfers.
