or formula based on a coin, currency, composite currency or currency unit other than that in which the Securities of the Series are denominated,
the manner in which such amounts shall be determined;


 


(o)  
whether the Securities of the Series will be issuable as Registered Securities (and if so, whether such Securities will be issuable
as Registered Global Securities) or Bearer Securities, with or without interest coupons appertaining thereto (and if so, whether such
Securities will be issuable as Bearer Global Securities), or any combination of the foregoing, any restrictions applicable to the offer,

at the same time and may be issued from time to time, consistent with the terms of this Indenture, if so provided by or pursuant to the
Board Resolution, supplemental indenture or Officers’ Certificate referred to above, and the authorized principal amount of any
Series may not be increased to provide for issuances of additional Securities of such Series, unless otherwise provided in such Board
Resolution, supplemental indenture or Officers’ Certificate.


 


Section 2.03.  
Execution and Authentication. One or more Officers shall sign the Securities for the Company by manual or facsimile signature.


 


If an Officer whose signature is on a Security
no longer holds that office at the time the Security is authenticated, the Security shall be valid nevertheless so long as such individual
was an Officer at the time of execution of the Security.


 




    7 


     


    

A Security shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent. The signature shall be conclusive evidence that the Security has been
authenticated under this Indenture.


 


The Trustee shall at any time, and from time to
time, authenticate Securities for original issue in the principal amount provided in the Board Resolution, supplemental indenture hereto
or Officers’ Certificate, upon receipt by the Trustee of a Company Order. Each Security shall be dated the date of its authentication
unless otherwise provided by a Board Resolution, a supplemental indenture hereto or an Officers’ Certificate.


 


The aggregate principal amount of Securities of
any Series outstanding at any time may not exceed any limit upon the maximum principal amount for such Series set forth in the Board Resolution,
supplemental indenture hereto or Officers’ Certificate delivered pursuant to ‎Section 2.02, except as provided in ‎Section
2.08.


 


Prior to the issuance of Securities of any Series,
the Trustee shall have received and (subject to ‎Section 7.02) shall be fully protected in relying on: (a) the Board Resolution, supplemental
indenture hereto or Officers’ Certificate establishing the form of the Securities of that Series or of Securities within that Series
and the terms of the Securities of that Series or of Securities within that Series, (b) an Officers’ Certificate complying with
‎Section 11.04, and (c) an Opinion of Counsel complying with ‎Section 11.04.


 


The Trustee shall have the right to decline to
authenticate and deliver any Securities of such Series: (a) if the Trustee, being advised by counsel, determines that such action may
not lawfully be taken; or (b) if the Trustee in good faith shall determine that such action would expose the Trustee to personal liability
to Holders of any then outstanding Series of Securities.


 


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


 


Section 2.04.  
Registrar and Paying Agent. The Company shall maintain, with respect to each Series of Securities, at the place or places
specified with respect to such Series pursuant to ‎Section 2.02, an office or agency where Securities of such Series may be
presented or surrendered for payment (“Paying Agent”), where Securities of such Series may be surrendered for registration
of transfer or exchange (“Registrar”) and where notices and demands to or upon the Company in respect of the Securities
of such Series and this Indenture may be served (“Service Agent”). The Registrar shall keep a register with respect
to each Series of Registered Securities (the “Register”) and to their transfer and exchange. The Company will give
prompt written notice to the Trustee of the name and address, and any change in the name or address, of each Registrar, Paying Agent or
Service Agent. If at any time the Company shall fail to maintain any such required Registrar, Paying Agent or Service Agent or shall fail
to furnish the Trustee with the name and address thereof, such presentations, surrenders, notices and demands may be made or served at
the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands; provided that the Corporate Trust Office shall not be an office or agency of the Company for the purpose
of effecting service of legal process on the Company.


 


The Company may also from time to time designate
one or more co-registrars, additional paying agents or additional service agents and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligations to maintain a Registrar,
Paying Agent and Service Agent in each place so specified pursuant to ‎Section 2.02 for Securities of any Series for such purposes.
The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the name or address
of any such co-registrar, additional paying agent or additional service agent. The term “Registrar” includes any co-registrar;
the term “Paying Agent” includes any additional paying agent; and the term “Service Agent” includes any additional
service agent.


 


The Company hereby appoints the Trustee as the
initial Registrar, Paying Agent and Service Agent for each Series unless another Registrar, Paying Agent or Service Agent, as the case
may be, is appointed prior to the time Securities of that Series are first issued. The Company or any of its domestically organized Subsidiaries
may act as


 




    8 


     


    

Paying Agent, Registrar or Service Agent. So long
as the Trustee is the Service Agent, no service of legal process on the Company may be made on the Service Agent.


 


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


 


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


 


The Company may remove any Registrar, Paying Agent
or Service Agent for any Series of Securities upon written notice to such Registrar, Paying Agent or Service Agent and to the Trustee;
provided, however, that no such removal shall become effective until (1) acceptance of an appointment by a successor as evidenced by an
appropriate agreement entered into by the Company and such successor Registrar, Paying Agent or Service Agent, as the case may be, and
delivered to the Trustee or (2) notification to the Trustee that the Trustee shall serve as Registrar, Paying Agent or Service Agent,
as the case may be, until the appointment of a successor in accordance with clause (1) above. The Registrar, Paying Agent or Service Agent
may resign at any time upon written notice; provided, however, that the Trustee may resign as Paying Agent, Registrar or Service Agent
only if the Trustee also resigns as Trustee in accordance with ‎Section 7.08. Upon any Event of Default under ‎Section 6.01(e)
or ‎Section 6.01(f), the Trustee shall automatically be the Paying Agent.


 


Section 2.05.  
Paying Agent to Hold Money in Trust. Prior to each due date of the principal and interest on any Series of Securities, the
Company shall deposit with the Paying Agent (or if the Company or a Subsidiary is acting as Paying Agent, segregate and hold in trust
for the benefit of the Persons entitled thereto) a sum sufficient to pay such principal and interest when so becoming due. The Company
shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent will hold in trust, for the benefit
of Securityholders of any Series of Securities, or the Trustee, all money held by the Paying Agent for the payment of principal of or
interest on the Series of Securities, and shall notify the Trustee of any default by the Company in making any such payment. While any
such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the
Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it shall
segregate and hold in a separate trust fund for the benefit of Securityholders of any Series of Securities all money held by it as Paying
Agent.


 


Section 2.06.  
Securityholder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list
available to it of the names and addresses of Securityholders of each Series of Securities and shall otherwise comply with TIA §
312(a). If the Trustee is not the Registrar, the Company shall furnish, or cause the Registrar to furnish, to the Trustee at least five
Business Days before each interest payment date, but in any event not less frequently than semi-annually, and at such other times as the
Trustee may request in writing a list, in such form and as of such date as the Trustee may reasonably require, of the names and addresses
of Securityholders of each Series of Securities.


 


Section 2.07.  
Exchange and Registration of Transfer. The Company shall cause to be kept at the Corporate Trust Office the Register in
which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities of a Series
and of transfers of Securities of such Series. The Register shall be in written form or in any form capable of being converted into written
form within a reasonably prompt period of time.


 


Upon surrender for registration of transfer of
any Security of a Series to the Registrar or any co-registrar, and satisfaction of the requirements for such transfer set forth in this
‎Section 2.07, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Security of the same Series of any authorized denominations and of a like aggregate principal amount and
bearing such restrictive legends as may be required by this Indenture.


 




    9 


     


    

Securities of a Series may be exchanged for other
Securities of the same Series of any authorized denominations and of a like aggregate principal amount, upon surrender of the Securities
to be exchanged at any such office or agency maintained by the Company pursuant to ‎Section 4.05. Whenever any Securities of a Series
are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities of the same
Series that the Holder making the exchange is entitled to receive bearing registration numbers not contemporaneously outstanding.


 


All Securities of a Series issued upon any registration
of transfer or exchange of Securities of the same Series shall be the valid obligations of the Company, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Securities of the same Series surrendered upon such registration of transfer
or exchange.


 


All Securities of a Series presented or surrendered
for registration of transfer or for exchange shall (if so required by the Company or the Registrar) be duly endorsed, or be accompanied
by a written instrument or instruments of transfer in form satisfactory to the Company, and the Securities of such Series shall be duly
executed by the Holder thereof or his attorney duly authorized in writing.


 


No service charge shall be made to any holder for
any registration of, transfer or exchange of Securities, but the Company or the Trustee may require payment by the holder of a sum sufficient
to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange
of such Securities (other than any such transfer tax or similar governmental charge payable upon exchanges pursuant to Sections ‎2.11,
‎3.06 or ‎9.06).


 


Neither the Company nor the Trustee nor any Registrar
shall be required to exchange, issue or register a transfer of (a) Securities of any Series for a period of fifteen calendar days next
preceding date of mailing of a notice of redemption of Securities of that Series selected for redemption, or (b) Securities of any Series
or portions thereof called for redemption, except for the unredeemed portion of any Securities of that Series being redeemed in part.


 


Section 2.08.  
Mutilated, Destroyed, Lost and Stolen Securities. If a mutilated Security is surrendered to the Registrar or if the Securityholder
of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate
and deliver a replacement Security of the same Series if the requirements of Section 8-405 of the Uniform Commercial Code are met, such
that the Securityholder (a) satisfies the Company or the Trustee within a reasonable time after he has notice of such loss, destruction
or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the
Company or the Trustee prior to the Security being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial
Code (a “protected purchaser”) and (c) satisfies any other reasonable requirements of the Company or the Trustee. If
required by the Trustee or the Company, such Securityholder shall furnish an indemnity bond sufficient in the judgment of the Trustee
to protect the Trustee and any Agent and in the judgment of the Company to protect the Company, the Trustee, the Paying Agent and the
Registrar from any loss that any of them may suffer if a Security is replaced. The Company and the Trustee may charge the Securityholder
for their expenses in replacing a Security. In case any Security which has matured or is about to mature or has been called for redemption,
shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Security, pay or authorize the
payment of (without surrender thereof except in the case of a mutilated Security), as the case may be, if the applicant for such payment
or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity
as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or in connection with such
substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, the Trustee and, if applicable,
any Paying Agent evidence to their satisfaction of the destruction, loss or theft of such Securities and of the ownership thereof.


 


Every replacement Security of any Series issued
pursuant to this Section is an additional obligation of the Company, evidencing the same debt, and entitled to the same benefits under
this Indenture, as the Securities of the same Series replaced.


 


The provisions of this Section are exclusive and
shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities.


 




    10 


     


    

Section 2.09.  
Outstanding Securities. The Securities outstanding at any time are all the Securities authenticated by the Trustee except
for those cancelled by it, those delivered to it for cancellation, those reductions in the interest on a Registered Global Security effected
by the Trustee in accordance with the provisions hereof and those described in this Section as not outstanding. A Security does not cease
to be outstanding because the Company or an Affiliate holds the Security.


 


If a Security is replaced pursuant to ‎Section
2.08, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is
held by a protected purchaser.


 


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


 


In determining whether the Holders of the requisite
principal amount of outstanding Securities have given any request, demand, authorization, direction, notice, consent or waiver hereunder,
the principal amount of a Discount Security that shall be deemed to be outstanding for such purposes shall be the amount of the principal
thereof that would be due and payable as of the date of such determination upon a declaration of acceleration of the Maturity thereof
pursuant to ‎Section 6.02.


 


Section 2.10.  
Treasury Securities. In determining whether the Holders of the required principal amount of Securities of a Series have
concurred in any direction, waiver or consent, Securities of a Series owned by the Company, any other obligor upon the Securities or an
Affiliate of the Company or such other obligor shall be disregarded and deemed not to be outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such direction, waiver or consent only Securities of a Series that
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 satisfaction of the Trustee the pledgee’s right so to act with respect to such Securities and
that the pledgee is not the Company or any other obligor upon the Securities or any Affiliate of the Company 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 written request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’
Certificate listing and identifying all Securities, if any, known by the Company to be owned or held by or for the account of any of the
above-described persons; and, subject to Sections ‎7.01 and ‎7.02, 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 2.11.  
Temporary Securities. Pending the preparation of Securities in certificated form, the Company may execute and the Trustee
or an authenticating agent appointed by the Trustee shall, upon a Company Order, authenticate and deliver temporary Securities (printed,
lithographed, typewritten, photocopied or otherwise produced). Temporary Securities shall be issuable in any authorized denomination,
and substantially in the form of the Securities in certificated form, but with such omissions, insertions and variations as may be appropriate
for temporary Securities, all as may be determined by the Company. Every such temporary Security shall be executed by the Company and
authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the
same effect, as the Securities in certificated form. Without unreasonable delay, the Company will execute and deliver to the Trustee or
such authenticating agent Securities of the same Series in certificated form and thereupon any or all temporary Securities may be surrendered
in exchange therefor, at each office or agency maintained by the Company pursuant to ‎Section 4.06 and the Trustee or such
authenticating agent shall authenticate and make available for delivery in exchange for such temporary Securities an equal aggregate principal
amount of Securities of the same Series in certificated form. Such exchange shall be made by the Company at its own expense and without
any charge therefor. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits and subject to
the same limitations under this Indenture as Securities of the same Series in certificated form authenticated and delivered hereunder.


 


Section 2.12.  
Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying
Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and
no one else shall cancel all Securities surrendered for


 




    11 


     


    

registration of transfer, exchange, payment, replacement
or cancellation and dispose of such cancelled Securities in accordance with its customary procedure. The Company may not issue new Securities
to replace Securities that it has paid or delivered to the Trustee for cancellation. The Trustee shall not authenticate Securities in
place of cancelled Securities other than pursuant to the terms of this Indenture.


 


Section 2.13.  
Defaulted Interest. If the Company defaults in a payment of interest on a Series of Securities, it shall pay the defaulted
interest, plus, to the extent permitted by law, any interest payable on the defaulted interest, to the Persons who are Securityholders
of the Series on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment
date to the reasonable satisfaction of the Trustee and shall promptly mail or cause to be mailed or deliver by electronic transmission
to each Securityholder of the Series a notice that states the special record date, the payment date and the amount of defaulted interest
to be paid. The Company may pay defaulted interest in any lawful manner.


 


Section 2.14.  
Registered Global Securities.


 


(a)  
Terms of Securities. A Board Resolution, a supplemental indenture hereto or an Officers’ Certificate shall establish
whether the Securities of a Series shall be issued in whole or in part in the form of one or more Registered Global Securities and the
Depositary for such Registered Global Security or Securities.


 


(b)  
Transfer and Exchange. Notwithstanding any provisions to the contrary contained in ‎Section 2.07 of the Indenture
and in addition thereto, any Registered Global Security shall be exchangeable pursuant to ‎Section 2.07 of the Indenture for
Securities registered in the names of Holders other than the Depositary for such Security or its nominee only if (i) such Depositary notifies
the Company that it is unwilling or unable to continue as Depositary for such Registered Global Security or if at any time such Depositary
ceases to be a clearing agency registered under the Exchange Act, and, in either case, the Company fails to appoint a successor Depositary
within 90 days of such event or (ii) the Company executes and delivers to the Trustee an Officers’ Certificate to the effect that
such Registered Global Security shall be so exchangeable. Any Registered Global Security that is exchangeable pursuant to the preceding
sentence shall be exchangeable for Securities registered in such names as the Depositary shall direct in writing in an aggregate principal
amount equal to the principal amount of the Registered Global Security with like tenor and terms.


 


Except as provided in this ‎Section 2.14(b),
a Registered Global Security may not be transferred except as a whole by the Depositary with respect to such Registered Global Security
to a nominee of such Depositary, by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by the Depositary
or any such nominee to a successor Depositary or a nominee of such a successor Depositary.


 


(c)  
Legend. Any Registered Global Security issued hereunder shall bear a legend in substantially the following form:


 


“This Security is a Registered Global Security within
the meaning of the Indenture hereinafter referred to and is registered in the name of the Depositary or a nominee of the Depositary. This
Security is exchangeable for Securities registered in the name of a Person other than the Depositary or its nominee only in the limited
circumstances described in the Indenture, and may not be transferred except as a whole by the Depositary to a nominee of the Depositary,
by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor
Depositary or a nominee of such a successor Depositary.”


 


(d)  
Acts of Holders. The Depositary, as a Holder, may appoint agents and otherwise authorize participants to give or take any
request, demand, authorization, direction, notice, consent, waiver or other action which a Holder is entitled to give or take under the
Indenture.


 


(e)  
Payments. Notwithstanding the other provisions of this Indenture, unless otherwise specified as contemplated by ‎Section
2.02, payment of the principal of and interest, if any, on any Registered Global Security shall be made to the Holder thereof.


 


(f)  
Consents, Declaration and Directions. Except as provided in ‎Section 2.14(d), the Company, the Trustee and any
Agent shall treat a Person as the Holder of such principal amount of outstanding Securities of such


 




    12 


     


    

Series represented by a Registered Global Security
as shall be specified in a written statement of the Depositary with respect to such Registered Global Security, for purposes of obtaining
any consents, declarations, waivers or directions required to be given by the Holders pursuant to this Indenture.


 


Section 2.15.  
Computation of Interest. Except as otherwise specified pursuant to ‎Section 2.02 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.


 


Section 2.16.  
CUSIP and ISIN Numbers. The Company in issuing the Securities may use “CUSIP” and “ISIN” numbers
(if then generally in use), and, if so, the Trustee shall use “CUSIP” and “ISIN” numbers in notices of redemption
as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other elements
of identification printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers.
The Company shall promptly notify the Trustee in writing of any changes to the CUSIP and ISIN numbers.


 


Article
3

Section 3.01.  
Notice to Trustee. The Company may, with respect to any Series of Securities, reserve the right to redeem and pay the Series
of Securities or may covenant to redeem and pay the Series of Securities or any part thereof prior to the Stated Maturity thereof at such
time and on such terms as provided for in such Securities. If a Series of Securities is redeemable and the Company wants or is obligated
to redeem prior to the Stated Maturity thereof all or part of the Series of Securities pursuant to the terms of such Securities, it shall
notify the Trustee in writing of the redemption date and the principal amount of Series of Securities to be redeemed. The Company shall
give the notice at least 35 calendar days before the redemption date (or such shorter notice as may be acceptable to the Trustee).


 


Section 3.02.  
Selection of Securities to Be Redeemed. Unless otherwise indicated for a particular Series by a Board Resolution, a supplemental
indenture or an Officers’ Certificate, if less than all the Securities of a Series are to be redeemed, the Trustee shall select
the Securities of the Series to be redeemed in any manner that the Trustee deems fair and appropriate. The Trustee shall make the selection
from Securities of the Series outstanding not previously called for redemption. The Trustee may select for redemption portions of the
principal of Securities of the Series that have denominations larger than $1,000. Securities of the Series and portions of them it selects
shall be in amounts of $1,000 or whole multiples of $1,000 or, with respect to Securities of any Series issuable in other denominations
pursuant to ‎Section 2.02(j), the minimum principal denomination for each Series and integral multiples thereof. Provisions
of this Indenture that apply to Securities of a Series called for redemption also apply to portions of Securities of that Series called
for redemption.


 


Section 3.03.  
Notice of Redemption. Unless otherwise indicated for a particular Series by Board Resolution, a supplemental indenture hereto
or an Officers’ Certificate, at least 10 days but not more than 60 days before a redemption date, the Company shall provide a notice
of redemption by electronic transmission or first-class mail to each Holder whose Securities are to be redeemed and if any Bearer Securities
are outstanding, publish on one occasion a notice in an Authorized Newspaper.


 


The notice shall identify the Securities of the
Series to be redeemed and shall state:


 


(a)  
the redemption date;


 


(b)  
the redemption price, or if not then ascertainable, the manner of calculation thereof;


 


(c)  
the name and address of the Paying Agent;


 


(d)  
if less than all Securities of any Series are to be redeemed, the identification of the particular Securities to be redeemed and
the portion of the principal amount of any Security to be redeemed in part;

the nature of any conditions precedent to the Company’s obligation to redeem the Securities on the redemption date; and


 


(h)  
any other information as may be required by the terms of the particular Series or the Securities of a Series being redeemed.


 


At the Company’s written request, the Trustee
shall give the notice of redemption in the Company’s name and at the Company’s expense and provided that the form and content
of such notice shall be prepared by the Company.


 


Section 3.04.  
Effect of Notice of Redemption. Once notice of redemption is transmitted, mailed or published as provided in ‎Section
3.03, Securities of a Series called for redemption become due and payable on the redemption date and at the redemption price. Upon surrender
to the Paying Agent, such Securities shall be paid at the redemption price plus accrued interest to, but excluding, the redemption date.


 


Section 3.05.  
Deposit of Redemption Price. On or before the redemption date, the Company shall deposit with the Paying Agent money sufficient
to pay the redemption price of and accrued interest, if any, on all Securities to be redeemed on that date.

Whenever the Company shall have one or more Paying
Agents for the Securities of any Series, it shall, on or before each due date of the principal of and premium, if any, and interest, if
any, on such Securities, deposit with such Paying Agents sums sufficient (without duplication) to pay the principal and premium or interest
so becoming due, such sums to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless
such Paying Agent is the Trustee) the Company shall promptly notify the Trustee of any failure by it so to act.


 


The Company shall cause each Paying Agent for the
Securities of any Series, other than the Company or the Trustee, to execute and deliver to the Trustee an instrument in which such Paying
Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent shall:


 


(i)  
hold all sums held by it for the payment of the principal of and premium, if any, or interest, if any, on such Securities in trust
for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided;

give the Trustee notice of any failure by the Company (or any other obligor upon such Securities) to make any payment of principal
of or premium, if any, or interest, if any, on such Securities; and

sums so held in trust by such Paying Agent and furnish to the Trustee such information as it possesses regarding the names and addresses
of the Persons entitled to such sums.


 


The Company may at any time pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held
by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent and, if so stated in a
Company Order delivered to the Trustee, in accordance with the provisions of ‎Article 8; and, upon such payment by any Paying Agent
to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.


 




    15 


     


    

Any money deposited with the Trustee or any Paying
Agent, or then held by the Company, in trust for the payment of the principal of and premium, if any, or interest, if any, on any Security
and remaining unclaimed for two years after such principal and premium, if any, or interest, if any, has become due and payable shall
be paid to the Company on request of the Company, or, if then held by the Company, shall be discharged from such trust; and, upon such
payment or discharge, the Holder of such Security shall, as an unsecured general creditor and not as the Holder of an outstanding Security,
look only to the Company for payment of the amount so due and payable and remaining unpaid, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however,
that the Trustee or such Paying Agent, before being required to make any such payment to the Company, may at the expense of the Company
cause to be published once a week for two successive weeks, in each case on any day of the week, in an Authorized Newspaper in each Place
of Payment, 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 paid to the Company.


 


Section 4.07.  
Waiver of Certain Covenants. Except as otherwise specified as contemplated by ‎Section 2.02 for Securities of

or condition set forth in any covenant provided herein or pursuant to ‎Section 2.02(s) or ‎Section 9.01(c) for the
benefit of the Holders of such Series if before the time for such compliance the Holders of at least 50% in principal amount of the outstanding
Securities of such Series shall, by an Act of such Holders, either waive such compliance in such instance or generally waive compliance
with such term, provision or condition, but no such wavier shall extend to or affect such term, provision or condition except to the extent
so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect
of such term, provision or condition shall remain in full force and effect.

Section 6.02.  
Acceleration of Maturity; Rescission and Annulment. If an Event of Default described in ‎Section 6.01(a), ‎(b)
or ‎(c) occurs and is continuing, then, and in each and every such case, except for any series of Securities the principal
of which 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 each such affected series then outstanding hereunder (each such series voting as a separate class) by notice in writing
to the Company (and to the Trustee if given by Securityholders), may declare the entire principal (or, if the Securities of such series
are 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.


 


Except as otherwise provided in the terms of any
series of Senior Securities pursuant to ‎Section 2.02, if an Event of Default described in ‎‎‎Section 6.01(d) or ‎(g)

of not less than 25% in aggregate principal amount of all of the Senior Securities then outstanding hereunder (treated as one class) by
notice in writing to the Company (and to the Trustee if given by Securityholders), may declare the entire principal (or, if the Senior
Securities of any series are Discount Securities, such portion of the principal amount as may be specified in the terms of such series)
of all of the Senior Securities then outstanding, and the interest accrued thereon, if any, to be due and payable immediately, and upon
such declaration, the same shall become immediately due and payable. If an Event of Default described in ‎Section 6.01(e) or ‎6.01(f)
above occurs and is continuing, then the principal amount of all the Senior Securities then outstanding, and the interest accrued thereon,
if any, shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.


 


Except as otherwise provided in the terms of any
series of Subordinated Securities pursuant to ‎Section 2.02,, if an Event of Default described in ‎‎‎Section 6.01(d) or
‎(g) above with respect to all series of Subordinated Securities then outstanding, occurs and is continuing, then, and in each and
every such case, unless the principal of all of the Subordinated Securities shall have already become due and payable, either the Trustee
or the Holders of not less than 25% in aggregate principal amount of all of the Subordinated Securities then outstanding hereunder (treated
as one class) by notice in writing to the Company (and to the Trustee if given by Securityholders), may declare the entire principal (or,
if the Subordinated Securities of any series are Discount Securities, such portion of the principal amount as may be specified in the
terms of such series) of all of the Subordinated Securities then outstanding, and the interest accrued thereon, if any, to be due and
payable immediately, and upon such declaration, the same shall become immediately due and payable.


 


If an Event of Default described in ‎‎‎Section
6.01(d) or ‎(g) occurs and is continuing, which Event of Default is with respect to less than all series of Senior Securities then
outstanding, then, and in each and every such case, except for any series of Senior Securities the principal of which shall have already
become due and payable, either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Senior Securities
of each such affected series then outstanding hereunder (each such series voting as a separate class) by notice in writing to the Company
(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.


 


If an Event of Default described in ‎‎‎Section
6.01(d) or ‎(g) occurs and is continuing, which Event of Default is with respect to less than all series of Subordinated Securities

have already become due and payable, either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Subordinated
Securities of each such affected series then outstanding hereunder (each such series voting as a separate class) by notice in writing
to the Company (and to the Trustee if given by Securityholders), may declare the entire principal (or, if the Securities of such series
are 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.


 




    18 


     


    

If an Event of Default specified in ‎Section
6.01(e) or ‎(f) shall occur, the principal amount (or specified amount) of and accrued and unpaid interest, if any, on all outstanding
Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee
or any Holder.


 


At any time after such a declaration of acceleration
with respect to any Series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee
as hereinafter in this Article provided, the Holders of a majority in principal amount of the outstanding Securities of that Series, by
written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:


 


(a)  
the Company has paid or deposited with the Trustee a sum sufficient to pay


 


(i)  
all overdue interest, if any, on all Securities of that Series;


 


(ii)  
the principal of any Securities of that Series which have become due otherwise than by such declaration of acceleration and interest
thereon at the rate or rates prescribed therefor in such Securities;


 


(iii)  
to the extent that payment of such interest is lawful, interest upon any overdue principal and overdue interest at the rate or
rates prescribed therefor in such Securities;


 


(iv)  
all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel; and


 


(v)  
all Events of Default with respect to Securities of that Series, other than the non-payment of the principal of Securities of that
Series which have become due solely by such declaration of acceleration, have been cured or waived as provided in ‎Section
6.13.


 


No such rescission shall affect any subsequent
Default or impair any right consequent thereon.


 


Section 6.03.  
Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if


 


(a)  
default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues
for a period of 30 days, or


 


(b)  
default is made in the payment of principal of any Security when due at the Maturity thereof, or


 


(c)  
default is made in the deposit of any sinking fund payment when and as due by the terms of a Security, then, the Company will,
upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such
Securities for principal and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue
principal or any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel.


 


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


 


If an Event of Default with respect to any Securities
of any Series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of
the Holders of Securities of such Series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect
and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise
of any power granted herein, or to enforce any other proper remedy.

Section 6.04.  
Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or
the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the 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 on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding
or otherwise,


 


(a)  
 to file and prove a claim for the whole amount of principal and interest owing and unpaid in respect of the Securities and to
file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in
such judicial proceeding, and


 


(b)  
to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same,


 


and any custodian, receiver, assignee, trustee, liquidator, sequestrator
or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and,
in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due
it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts
due the Trustee under ‎Section 7.07


 


Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment
or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim
of any Holder in any such proceeding.


 


Section 6.05.  
Trustee May Enforce Claims without Possession of Securities. All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in
any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express
trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.


 


Section 6.06.  
Application of Money Collected. Any money or property collected by the Trustee pursuant to this Article shall be applied
in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money or property on account
of principal or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon
surrender thereof if fully paid:


 


First: To the payment of all amounts due
the Trustee under ‎Section 7.07; and


 


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


 


Third: To the Company.


 


Section 6.07.  
Limitation on Suits. No Holder of any Security of any Series shall have any right to institute any proceeding, judicial
or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless


 


(a)  
such Holder has previously given written notice to the Trustee of an Event of Default and the continuance thereof with respect
to the Securities of that Series;


 




    20 


     


    

(b)  
the Holders of not less than 25% in principal amount of the outstanding Securities of that Series shall have made written request
to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;


 


(c)  
such Holder or Holders have offered to the Trustee reasonable security or indemnity satisfactory to the Trustee against the expenses
and liabilities to be incurred in compliance with such request;


 


(d)  
the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding;
and


 


(e)  
no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a
majority in principal amount of the outstanding Securities of that Series;


 


it being understood and intended that no one or more of such Holders
shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice
the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to
enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders.


 


Section 6.08.  
Unconditional Right of Holders to Receive Principal and Interest. Notwithstanding any other provision in this Indenture,
the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and interest,
if any, on such Security on the Stated Maturity or Stated Maturities expressed in such Security (or, in the case of redemption, on the
redemption date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent
of such Holder.


 


Section 6.09.  
Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy
under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee
or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders
shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee
and the Holders shall continue as though no such proceeding had been instituted.


 


Section 6.10.  
Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities in ‎Section 2.08, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders
is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative
and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion
or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate
right or remedy.


 


Section 6.11.  
Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Securities to exercise any right
or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default
or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from
time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.


 


Section 6.12.  
Control by Holders. The Holders of a majority in principal amount of the outstanding Securities of any Series shall have
the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any
trust or power conferred on the Trustee, with respect to the Securities of such Series, provided that


 


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


 


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


 




    21 


     


    

(c)  
subject to the provisions of ‎Section 6.01, the Trustee shall have the right to decline to follow any such direction
if the Trustee in good faith shall, by a Trust Officer of the Trustee, determine that the proceeding so directed would involve the Trustee
in personal liability.


 


Section 6.13.  
Waiver of Past Defaults. The Holders of not less than a majority in principal amount of the outstanding Securities of any
Series may on behalf of the Holders of all the Securities of such Series waive any past Default hereunder with respect to such Series
and its consequences, except a Default in the payment of the principal of or interest on any Security of such Series (provided, however,
that the Holders of a majority in principal amount of the outstanding Securities of any Series may rescind an acceleration and its consequences,
including any related payment default that resulted from such acceleration). Upon any such waiver, such Default shall cease to exist,
and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver
shall extend to any subsequent or other Default or impair any right consequent thereon.


 


Section 6.14.  
Undertaking for 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

No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability

for believing that repayment of such funds or adequate indemnity against such risk is not reasonably assured to it.


 


(h)  
Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee
shall be subject to the provisions of this Section and to the provisions of the TIA.

(g)  
The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request,

    23 


     


    

(i)  
Delivery of reports, information and documents to the Trustee under ‎Section 4.02 is for informational purposes
only and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein or

the Trustee is entitled to rely exclusively on Officers’ Certificates).


 


(ii)  
Notwithstanding anything in this Indenture to the contrary, neither the Trustee nor any Agent shall be responsible or liable to
any person for any indirect, special, punitive or consequential damage or loss (including but not limited to lost profits) whatsoever,
even if the Trustee has been informed of the likelihood thereof and regardless of the form of action.


 


Section 7.03.  
Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or an Affiliate with the same rights it would have if it were not Trustee. Any Agent may do the
same with like rights. The Trustee is also subject to Sections ‎7.10 and ‎7.11.


 


Section 7.04.  
Trustee’s Disclaimer. The Trustee shall not be responsible and makes no representation as to the validity or adequacy
of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities, and
it shall not be responsible for any statement in the Securities or in any document issued in connection with the sale of the Securities
or in the Securities other than its certificate of authentication.


 


Section 7.05.  
Notice of Defaults. If a Default or Event of Default occurs and is continuing with respect to the Securities of any Series
and if it is known to a Trust Officer of the Trustee, the Trustee shall send to each Securityholder of the Securities of that Series and,
if any Bearer Securities are outstanding, publish on one occasion in an Authorized Newspaper, notice of a Default or Event of Default
within 90 days after it occurs or 30 days after it is known to a Trust Officer or written notice of it is received by the Trustee. Except
in the case of a Default or Event of Default in payment of principal, premium, if any, of or interest on any Security of any Series or
in payment of any redemption obligation, the Trustee may withhold the notice if and so long as its corporate trust committee or a committee
of its Trust Officers in good faith determines that withholding the notice is in the interests of Securityholders of that Series.


 


Section 7.06.  
Reports by Trustee to Holders. As promptly as practicable after each May 15 beginning with [____], and in any event prior
to July 15 in each year, the Trustee shall transmit by mail or by electronic transmission to all Securityholders, as their names and addresses
appear on the register kept by the Registrar and, if any Bearer Securities are outstanding, publish in an Authorized Newspaper, a brief
report dated as of May 15, each year if and to the extent required by TIA § 313(a). The Trustee shall also comply with TIA §
313(b) and TIA § 313(c).


 


A copy of each report at the time of its sending
to Securityholders of any Series shall be filed with the SEC and each stock exchange (if any) on which the Securities of that Series are
listed. The Company shall promptly notify the Trustee when Securities of any Series are listed on any stock exchange and of any delisting
thereof.


 


Section 7.07.  
Compensation and Indemnity. The Company shall pay to the Trustee from time to time such compensation as the Company and
the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by any law on compensation
of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred
or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable
compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company shall
indemnify the Trustee, its officers, directors, employees and agents, and hold each of them harmless, against any and all loss, liability
or expense (including reasonable attorneys’ fees) incurred by or in connection with the offer and sale of the Securities or the
administration of this trust and the performance of its duties hereunder. The Trustee shall notify the Company of any claim for which
it may seek indemnity promptly upon obtaining actual knowledge thereof; provided, however, that any failure so to notify the Company shall
not relieve the Company of its indemnity obligations hereunder. The Company shall defend the claim and the indemnified party shall provide
reasonable cooperation at the Company’s expense in the defense. Such indemnified parties may have separate counsel and the Company
shall pay the fees and expenses of such counsel; provided,


 




    24 


     


    

however, that the Company shall not be required to
pay such fees and expenses if it assumes such indemnified parties’ defense and, in such indemnified parties’ reasonable judgment,
there is no conflict of interest between the Company and such parties in connection with such defense. The Company need not reimburse
any expense or indemnify against any loss, liability or expense incurred by an indemnified party through such party’s own willful
misconduct and gross negligence.


 


To secure the Company’s payment obligations
in this Section, the Trustee shall have a lien prior to the Securities of any Series on all money or property held or collected by the
Trustee other than money or property held in trust to pay principal of and interest and any liquidated damages on particular Securities
of that Series.


 


The Company’s payment obligations pursuant
to this Section shall survive the satisfaction or discharge of this Indenture, any rejection or termination of this Indenture under any
bankruptcy law or the resignation or removal of the Trustee.


 


When the Trustee incurs expenses or renders services
after an Event of Default specified in ‎Section 6.01(f) or ‎(g) occurs, the expenses and the compensation for the services are
intended to constitute expenses of administration under any Bankruptcy Law.


 


Section 7.08.  
Replacement of Trustee. The Trustee may resign with respect to the Securities of one or more Series at any time by so notifying
the Company. The Holders of a majority in principal amount of the Securities of any Series may remove the Trustee with respect to that
Series by so notifying the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee with respect to Securities
of one or more Series if:


 


(a)  
the Trustee fails to comply with ‎Section 7.10;


 


(b)  
the Trustee is adjudged bankrupt or insolvent;


 


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


 


(d)  
the Trustee otherwise becomes incapable of acting.


 


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


 


A successor Trustee shall deliver a written acceptance
of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee with respect to each Series of Securities
for which it is acting as Trustee under this Indenture. The successor Trustee shall send a notice of its succession to each Securityholder
of each such Series and, if any Bearer Securities are outstanding, publish such notice on one occasion in an Authorized Newspaper. The
retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for
in ‎Section 7.07.


 


If a successor Trustee with respect to the Securities
of any one or more Series does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or
the Holders of 10% in principal amount of the Securities of the applicable Series may petition any court of competent jurisdiction for
the appointment of a successor Trustee.


 


If the Trustee with respect to the Securities of
any one or more Series fails to comply with ‎Section 7.10, any Securityholder of the applicable Series may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.


 


Notwithstanding the replacement of the Trustee
pursuant to this Section, the Company’s obligations under ‎Section 7.07 shall continue for the benefit of the retiring Trustee.


 




    25 


     


    

Section 7.09.  
Successor Trustee by Merger, etc. If the Trustee consolidates with, merges or converts into, or transfers all or substantially
all of its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation
without any further act shall be the successor Trustee.


 


In case at the time such successor or successors
by merger, conversion or consolidation to the Trustee with respect to the Securities of any one or more Series shall succeed to the trusts
created by this Indenture any of the Securities of the applicable Series shall have been authenticated but not delivered, any such successor
to such Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Securities of the applicable
Series so authenticated; and in case at that time any of the Securities of such 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 to the
Trustee; and in all such cases such certificates 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.


 


Section 7.10.  
Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA § 310(a). The Trustee
shall have a combined capital and surplus of at least $100,000,000 as set forth in its most recent published annual report of condition.
The Trustee shall comply with TIA § 310(b); provided, however, that there shall be excluded from the operation of TIA § 310(b)(1)
any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company
are outstanding if the requirements for such exclusion set forth in TIA § 310(b)(1) are met.


 


Section 7.11.  
Preferential Collection of Claims against Company. The Trustee shall comply with TIA § 311(a), excluding any creditor
relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent
indicated.

restriction, condition or provision such supplemental indenture may provide for a particular period of grace after default (which period

Section 9.02.  
With Consent of Holders. The Company and the Trustee may enter into a supplemental indenture with the written consent of
the Holders of at least a majority in principal amount of the outstanding Securities of each Series affected by such supplemental indenture
(including consents obtained in connection with a tender offer or exchange offer for the Securities of such Series), 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 Securityholders of each such Series. Except as provided in ‎Section 6.13, the
Holders of at least a majority in principal amount of the outstanding Securities of each Series affected by such waiver by notice to the
Trustee (including consents obtained in connection with a tender offer or exchange offer for the Securities of such Series) may waive
compliance by the Company with any provision of this Indenture or the Securities with respect to such Series.


 


It shall not be necessary for the consent of the
Holders of Securities under this ‎Section 9.02 to approve the particular form of any proposed supplemental indenture or waiver, but
it shall be sufficient if such consent approves the substance thereof. After a supplemental indenture or waiver under this section becomes
effective, the Company shall send to the Holders of Securities affected thereby and, if any Bearer Securities affected thereby are outstanding,
publish on one occasion in an Authorized Newspaper, a notice briefly describing the supplemental indenture or waiver. Any failure by the
Company to send or publish such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such
supplemental indenture or waiver.


 




    30 


     


    

Section 9.03.  
Limitations. Without the consent of each Securityholder affected, an amendment or waiver may not:


 


(a)  
extend the final maturity of any Security;


 


(b)  
reduce the principal amount thereof, or premium thereon, if any;


 


(c)  
reduce the rate or extend the time of payment of interest thereon;


 


(d)  
reduce any amount payable on redemption thereof;


 


(e)  
make the principal thereof (including any amount in respect of original issue discount), or premium thereon, if any, or interest
thereon payable in any coin or currency other than that provided in the Securities or in accordance with the terms thereof;


 


(f)  
reduce the amount of the principal of a Discount Security that would be due and payable upon an acceleration of the maturity thereof
pursuant to ‎Section 6.02 or the amount thereof provable in bankruptcy pursuant to ‎Section 6.04;


 


(g)  
in the case of Subordinated Securities of any series, modify any of the Subordination Provisions or the definition of “Senior

indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of this Indenture or certain
defaults hereunder and their consequences) provided for in this Indenture; or


 


(k)  
modify any provision of this ‎Section 9.03.


 


Section 9.04.  
Compliance with Trust Indenture Act. Every amendment to this Indenture or the Securities of one or more Series shall be
set forth in a supplemental indenture hereto that complies with the TIA as then in effect.


 


Section 9.05.  
Revocation and Effect of Consents. Until an amendment or waiver becomes effective, a consent to it by a Holder of a Security
is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt
as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent
Holder may revoke the consent as to his Security or portion of a Security if the Trustee receives the notice of revocation before the
date the amendment or waiver becomes effective.


 


Any amendment or waiver once effective shall bind
every Securityholder of each Series affected by such amendment or waiver unless it is of the type described in any of clauses ‎(a)
through ‎(g) of ‎Section 9.03. In that case, the amendment or waiver shall bind each Holder of a Security who has consented to
it and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security.


 


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


 




    31 


     


    

Section 9.06.  
Notation on or Exchange of Securities. The Trustee may place an appropriate notation about an amendment or waiver on any
Security of any Series thereafter authenticated. The Company in exchange for Securities of that Series may issue and the Trustee shall
authenticate upon written request new Securities of that Series that reflect the amendment or waiver.


 


Section 9.07.  
Trustee Protected. In executing, or accepting the additional trusts created by, any supplemental indenture permitted by
this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject
to ‎Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating
that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee shall sign all supplemental
indentures, except that the Trustee need not sign any supplemental indenture that adversely affects its rights.

In case, by reason of the suspension of or irregularities
in regular mail service, it shall be impracticable to mail notice by the Company 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.

applicable law or regulation to be open. If a payment date for the payment of principal or interest on any Security falls on a Legal Holiday,
such payment shall be made on the next succeeding Business Day, and no interest shall accrue for the intervening period. If a regular
record date is a Legal Holiday, the record date shall not be affected.

Governing Laws; Submission to Jurisdiction; Waiver of Jury Trial. THIS INDENTURE AND EACH SECURITY SHALL BE DEEMED TO BE

or relating to this Indenture or the Securities. The Company irrevocably waives, to the fullest extent permitted by law, any objection
which it may now or hereafter have to the laying of venue of any such suit, action or proceeding brought in such a court and any claim
that any such suit, action or proceeding brought in such a court has been brought in an inconvenient forum.

Table of Contents, Headings, Etc. The Table of Contents, Cross Reference Table, and headings of the Articles and Sections
of this Indenture have been inserted for convenience of reference only, are not to be considered a part hereof, and shall in no way modify

Section 11.15.  
Securities in a Foreign Currency. Unless otherwise specified in a Board Resolution, a supplemental indenture hereto or an
Officers’ Certificate delivered pursuant to ‎Section 2.02 of this Indenture with respect to a particular Series of Securities,
whenever for purposes of this Indenture any action may be taken by the Holders of a specified percentage in aggregate principal amount
of Securities of all Series or all Series affected by a particular action at the time outstanding and, at such time, there are outstanding
Securities of any Series which are denominated in a coin or currency other than Dollars, then the principal amount of Securities of such
Series which shall be deemed to be outstanding for the purpose of taking such action shall be that amount of Dollars that could be obtained
for such amount at the Market Exchange Rate at such time. For purposes of this ‎Section 11.15, “Market Exchange Rate”
shall mean the noon Dollar buying rate in New York City for cable transfers of that currency as published by the Federal Reserve Bank
of New York. If such Market Exchange Rate is not available for any reason with respect to such currency, the Trustee shall use, in its
sole discretion and without liability on its part, such quotation of the Federal Reserve Bank of New York or quotations from one or more
major banks in The City of New York or in the country of issue of the currency in question. The provisions of this paragraph shall apply
in


 




    34 


     


    

determining the equivalent principal amount in respect
of Securities of a Series denominated in currency other than Dollars in connection with any action taken by Holders of Securities pursuant
to the terms of this Indenture.


 


All decisions and determinations of the Trustee
regarding the Market Exchange Rate or any alternative determination provided for in the preceding paragraph shall be in its sole discretion
and shall, in the absence of manifest error, be conclusive to the extent permitted by law for all purposes and irrevocably binding upon
the Company and all Holders.


 


Section 11.16.  
Judgment Currency. The Company agrees, to the fullest extent that it may effectively do so under applicable law, that (a)
if for the purpose of obtaining judgment in any court it is necessary to convert the sum due in respect of the principal of or interest
or other amount on the Securities of any Series (the “Required Currency”) into a currency in which a judgment will
be rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in accordance with normal
banking procedures the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on the day on which
final unappealable judgment is entered, unless such day is not a New York Banking Day, then, the rate of exchange used shall be the rate
at which in accordance with normal banking procedures the Trustee could purchase in The City of New York the Required Currency with the
Judgment Currency on the New York Banking Day preceding the day on which final unappealable judgment is entered and (b) its obligations
under this Indenture to make payments in the Required Currency (i) shall not be discharged or satisfied by any tender, any recovery pursuant
to any judgment (whether or not entered in accordance with subsection (a)), in any currency other than the Required Currency, except to
the extent that such tender or recovery shall result in the actual receipt, by the payee, of the full amount of the Required Currency
expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or additional cause of action for the
purpose of recovering in the Required Currency the amount, if any, by which such actual receipt shall fall short of the full amount of
the Required Currency so expressed to be payable, and (iii) shall not be affected by judgment being obtained for any other sum due under
this Indenture. For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a
legal holiday in The City of New York on which banking institutions are authorized or required by law, regulation or executive order to
close.


 


Section 11.17.  
Acts of Holders. (a) 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 and, where it is hereby expressly required, to the Company. Such instrument or
instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “ACT”
of the Holders signing such instrument or instruments and so voting at any such meeting. 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 Sections ‎7.01 and
‎7.02) conclusive in favor of the Trustee and the Company, if made in the manner provided in this ‎Section 11.17.


 


(b)  
Subject to Sections ‎7.01 and ‎7.02, 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 satisfactory to the Trustee. The holding of Registered Securities shall be proved by the Security register or by a certificate
of the registrar thereof.


 


(c)  
The Company, the Trustee and any agent of the Company 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 Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to the contrary. The Company,
the Trustee and any agent of the Company or the Trustee may treat the Holder of any Bearer Security as the absolute owner of such Bearer
Security (whether or not such Bearer Security shall be overdue) for the purpose of receiving payment thereof or on account thereof and
for all other purposes, and neither the Company, the Trustee, nor any agent of the Company 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 Bearer


 




    35 


     


    

Security. Notwithstanding the foregoing, nothing
herein shall prevent the Company, the Trustee or any Agent from giving effect to any written certification, proxy or other authorization
furnished by the Depositary or impair, as between the Depositary and its members, the operation of customary practices governing the exercise
of the rights of a holder of a beneficial interest in any Registered Global Security.


 


(d)  
At any time prior to (but not after) the evidencing to the Trustee, as provided in this ‎Section 11.17, 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 Company, the Trustee and the Holders of all the Securities affected
by such action.


 


Section 11.18.  
Force Majeure. In no event shall the Trustee or any Agent be responsible or liable for any failure or delay in the performance
of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation,
strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts
of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood
that the Trustee and such Agent shall use reasonable efforts that are consistent with accepted practices in the banking industry to resume
performance as soon as practicable under the circumstances.

Sinking Funds


 


Section 12.01.  
Applicability of Article. The provisions of this Article shall be applicable to any sinking fund for the retirement of the
Securities of a Series, except as otherwise permitted or required by any form of Security of such Series issued pursuant to this Indenture.


 


The minimum amount of any sinking fund payment
provided for by the terms of the Securities of any Series is herein referred to as a “mandatory sinking fund payment” and
any other amount provided for by the terms of Securities of such Series is herein referred to as an “optional sinking fund payment.”
If provided for by the terms of Securities of any Series, the cash amount of any sinking fund payment may be subject to reduction as provided
in ‎Section 12.02. Each sinking fund payment shall be applied to the redemption of Securities of any Series as provided for by the
terms of the Securities of such Series.


 


Section 12.02.  
Satisfaction of Sinking Fund Payments with Securities. The Company may, in satisfaction of all or any part of any sinking
fund payment with respect to the Securities of any Series to be made pursuant to the terms of such Securities (a) deliver outstanding
Securities of such Series to which such sinking fund payment is applicable (other than any of such Securities previously called for mandatory
sinking fund redemption) and (b) apply as credit Securities of such Series to which such sinking fund payment is applicable and which
have been redeemed either at the election of the Company pursuant to the terms of such Series of Securities (except pursuant to any mandatory
sinking fund) or through the application of permitted optional sinking fund payments or other optional redemptions pursuant to the terms
of such Securities, provided that such Securities have not been previously so credited. Such Securities shall be received by the Trustee,
together with an Officers’ Certificate with respect thereto, not later than 15 days prior to the date on which the Trustee begins
the process of selecting Securities for redemption, and shall be credited for such purpose by the Trustee at the price specified in such
Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly.
If as a result of the delivery or credit of Securities in lieu of cash payments pursuant to this ‎Section 12.02, the principal
amount of Securities of such Series to be redeemed in order to exhaust the aforesaid cash payment shall be less than $100,000, the Trustee
need not call Securities of such Series for redemption, except upon receipt of a Company Order that such action be taken, and such cash
payment shall be held by the Trustee or a Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that
the Trustee or such


 




    36 


     


    

Paying Agent shall from time to time upon receipt
of a Company Order pay over and deliver to the Company any cash payment so being held by the Trustee or such Paying Agent upon delivery
by the Company to the Trustee of Securities of that Series purchased by the Company having an unpaid principal amount equal to the cash
payment required to be released to the Company.


 


Section 12.03.  
Redemption of Securities for Sinking Fund. Not less than 45 days (unless otherwise indicated in the Board Resolution, supplemental
indenture hereto or Officers’ Certificate in respect of a particular Series of Securities) prior to each sinking fund payment date
for any Series of Securities, the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next
ensuing mandatory sinking fund payment for that Series pursuant to the terms of that Series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting of Securities of
that Series pursuant to ‎Section 12.02, and the optional amount, if any, to be added in cash to the next ensuing mandatory
sinking fund payment, and the Company shall thereupon be obligated to pay the amount therein specified. Not less than 30 days (unless
otherwise indicated in the Board Resolution, Officers’ Certificate or supplemental indenture in respect of a particular Series of
Securities) before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment
date in the manner specified in ‎Section 3.02 and cause notice of the redemption thereof to be given in the name of and at
the expense of the Company in the manner provided in ‎Section 3.03. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections ‎3.04, ‎3.05 and ‎3.06.
