or are present at a meeting of Holders of Securities for quorum purposes, (i) the principal amount of an Original Issue Discount
Security that may be counted in making such determination and that shall be deemed to be Outstanding for such purposes shall be
equal to the amount of the principal thereof that pursuant to the terms of such Original Issue Discount Security would be declared
(or shall have been declared to be) due and payable upon a declaration of acceleration thereof pursuant to Section 5.2 at the time
of such determination, and (ii) the principal amount of any Indexed Security that may be counted in making such determination and

to such Securities and (B) that the pledgee is not the Company or any other obligor upon the Securities or any Coupons appertaining
thereto or an Affiliate of the Company or such other obligor.

authorization, direction, notice, consent, waiver or other action provided in or pursuant to this Indenture to be given or taken
by Holders of Securities of such series may, alternatively, be embodied in and evidenced by the record of Holders of Securities
of such series voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders of
Securities of such series duly called and held in accordance with the provisions of Article 15, or a combination of such instruments
and any such record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or
instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument
or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as
the “Act” of the Holders signing such instrument or instruments or so voting at any such meeting. Proof of execution
of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient
for any purpose of this Indenture and (subject to Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee and
the Company and any agent of the Trustee and the Company, if made in the manner provided in this Section. The record of any meeting
of Holders of Securities shall be proved in the manner provided in Section 15.6.

 

Without limiting the generality of this
Section 1.4, unless otherwise provided in or pursuant to this Indenture, a Holder, including a U.S. Depository that is a Holder
of a global Security, may make, give or take, by a proxy or proxies, duly appointed in writing, any request, demand, authorization,
direction, notice, consent, waiver or other Act provided in or pursuant to this Indenture to be made, given or taken by Holders,
and a U.S. Depository that is a Holder of a global Security may provide its proxy or proxies to the beneficial owners of interests
in any such global Security through such U.S. Depository’s standing instructions and customary practices.

 

    - 15 -

     

    

 

The Company shall fix a record date for
the purpose of determining the Persons who are beneficial owners of interest in any permanent global Security held by a U.S. Depository
entitled under the procedures of such U.S. Depository to make, give or take, by a proxy or proxies duly appointed in writing, any
request, demand, authorization, direction, notice, consent, waiver or other Act provided in or pursuant to this Indenture to be
made, given or taken by Holders. If such a record date is fixed, the Holders on such record date or their duly appointed proxy
or proxies, and only such Persons, shall be entitled to make, give or take such request, demand, authorization, direction, notice,
consent, waiver or other Act, whether or not such Holders remain Holders after such record date. No such request, demand, authorization,
direction, notice, consent, waiver or other Act shall be valid or effective if made, given or taken more than 90 days after such
record date.

 

(2) The fact and date of the execution by
any Person of any such instrument or writing referred to in this Section 1.4 may be proved in any reasonable manner; and the Trustee
may in any instance require further proof with respect to any of the matters referred to in this Section.

 

(3) The ownership, principal amount and
serial numbers of Registered Securities held by any Person, and the date of the commencement and the date of the termination of
holding the same, shall be proved by the Security Register.

 

(4) The ownership, principal amount and
serial numbers of Bearer Securities held by any Person, and the date of the commencement and the date of the termination of holding
the same, may be proved by the production of such Bearer Securities or by a certificate executed, as depositary, by any trust company,
bank, banker or other depositary reasonably acceptable to the Company, wherever situated, if such certificate shall be deemed by
the Company and the Trustee to be satisfactory, showing that at the date therein mentioned such Person had on deposit with such
depositary, or exhibited to it, the Bearer Securities therein described; or such facts may be proved by the certificate or affidavit
of the Person holding such Bearer Securities, if such certificate or affidavit is deemed by the Trustee to be satisfactory. The
Trustee and the Company may assume that such ownership of any Bearer Security continues until (i) another certificate or affidavit
bearing a later date issued in respect of the same Bearer Security is produced, or (ii) such Bearer Security is produced to the
Trustee by some other Person, or (iii) such Bearer Security is surrendered in exchange for a Registered Security, or (iv) such
Bearer Security is no longer Outstanding. The ownership, principal amount and serial numbers of Bearer Securities held by the Person
so executing such instrument or writing and the date of the commencement and the date of the termination of holding the same may
also be proved in any other manner which the Company and the Trustee deem sufficient.

 

(5) If the Company shall solicit from the
Holders of any Registered Securities any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company
may at its option (but is not obligated to), by Board Resolution, fix in advance a record date for the determination of Holders
of Registered Securities entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act.
If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of Registered Securities of record at the close of business on such record
date shall be deemed to be Holders for the purpose of determining whether Holders of the requisite proportion of Outstanding Securities
have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act,
and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization,
agreement or consent by the Holders of Registered Securities shall be deemed effective unless it shall become effective pursuant
to the provisions of this Indenture not later than six months after the record date.

 

    - 16 -

     

    

 

(6) Any request, demand, authorization,
direction, notice, consent, waiver or other Act by the Holder of any Security shall bind every future Holder of the same Security
and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done or suffered to be done by the Trustee, any Security Registrar, any Paying Agent or the Company in reliance
thereon, whether or not notation of such Act is made upon such Security.

 

Section 1.5. Notices, Etc. to the Trustee and the Company.

 

Any request, demand, authorization, direction,
notice, consent, waiver or other Act of Holders or other document provided or permitted by this Indenture to be made upon, given
or furnished to, or filed with,

 

(1) the Trustee by any Holder or the Company
shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate
Trust Office, or

 

(2) the Company by the Trustee or any Holder
shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class
postage prepaid, to the Company addressed to the attention of its Chief Financial Officer, Chief Accounting Officer or Secretary,
at the address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished
in writing to the Trustee by the Company.

 

Section 1.6. Notice to Holders of Securities; Waiver.

 

Except as otherwise expressly provided in
or pursuant to this Indenture, where this Indenture provides for notice to Holders of Securities of any event,

 

(1) such notice shall be sufficiently given
to Holders of Registered Securities if in writing and mailed, first-class postage prepaid, to each Holder of a Registered Security
affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier
than the earliest date, prescribed for the giving of such notice; and

 

(2) such notice shall be sufficiently given
to Holders of Bearer Securities, if any, if published in an Authorized Newspaper in The City of New York and, if such Securities
are then listed on any stock exchange outside the United States, in an Authorized Newspaper in such city as the Company shall advise
the Trustee that such stock exchange so requires, on a Business Day at least twice, the first such publication to be not earlier
than the earliest date and the second such publication not later than the latest date prescribed for the giving of such notice.

 

In any case where notice to Holders of Registered
Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular
Holder of a Registered Security shall affect the sufficiency of such notice with respect to other Holders of Registered Securities
or the sufficiency of any notice to Holders of Bearer Securities given as provided herein. Any notice which is mailed in the manner
herein provided shall be conclusively presumed to have been duly given or provided. In the case by reason of the suspension of
regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification
as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

 

In case by reason of the suspension of publication
of any Authorized Newspaper or Authorized Newspapers or by reason of any other cause it shall be impracticable to publish any notice
to Holders of Bearers Securities as provided above, then such notification to Holders of Bearer Securities as shall be given with
the approval of the Trustee shall constitute sufficient notice to such Holders for every purpose hereunder. Neither failure to
give notice by publication to Holders of Bearer Securities as provided above, nor any defect in any notice so published, shall
affect the sufficiency of any notice mailed to Holders of Registered Securities as provided above.

 

    - 17 -

     

    

 

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 of Securities 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.

 

Section 1.7. Language of Notices.

 

Any request, demand, authorization, direction,
notice, consent, election or waiver required or permitted under this Indenture shall be in the English language, except that, if
the Company so elects, any published notice may be in an official language of the country of publication.

 

Section 1.8. Conflict with Trust Indenture Act.

 

If any provision hereof limits, qualifies
or conflicts with any duties under any required provision of the Trust Indenture Act imposed hereon by Section 318(c) thereof,

or the last date on which a Holder has the right to convert or exchange Securities of a series that are convertible or exchangeable,
shall be a Legal Holiday at any Place of Payment, then (notwithstanding any other provision of this Indenture, any Security or
any Coupon other than a provision in any Security or Coupon that specifically states that such provision shall apply in lieu hereof)

Currency (i) shall not be discharged or satisfied by any tender, or any recovery pursuant to any judgment (whether or not entered
in accordance with clause (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

as are required or permitted by or pursuant to this Indenture or any indenture supplemental hereto and may have such letters, numbers
or other marks of identification and such legends or endorsements placed thereon as may, consistently herewith, be determined by
the officers executing such Security or Coupon as evidenced by their execution of such Security or Coupon.

 

Unless otherwise provided in or pursuant
to this Indenture or any Securities, the Securities shall be issuable in registered form without Coupons and shall not be issuable
upon the exercise of warrants.

 

Definitive Securities and definitive Coupons
shall be printed, lithographed or engraved or produced by any combination of these methods on a steel engraved border or steel
engraved borders or may be produced in any other manner, all as determined by the officers of the Company executing such Securities
or Coupons, as evidenced by their execution of such Securities or Coupons.

Section 2.3. Securities in Global Form.

 

Unless otherwise provided in or pursuant
to this Indenture or any Securities, the Securities shall not be issuable in temporary or permanent global form. If Securities
of a series shall be issuable in global form, any such Security may provide that it or any number of such Securities shall represent
the aggregate amount of all Outstanding Securities of such series (or such lesser amount as is permitted by the terms thereof)
from time to time endorsed thereon and may also provide that the aggregate amount of Outstanding Securities represented thereby
may from time to time be increased or reduced to reflect exchanges. Any endorsement of any Security in global form to reflect the
amount, or any increase or decrease in the amount, or changes in the rights of Holders, of Outstanding Securities represented thereby
shall be made in such manner and by such Person or Persons as shall be specified therein or in the Company Order to be delivered
pursuant to Section 3.3 or 3.4 with respect thereto. Subject to the provisions of Section 3.3 and, if applicable, Section 3.4,
the Trustee shall deliver and redeliver, in each case at the Company’s expense, any Security in permanent global form in
the manner and upon instructions given by the Person or Persons specified therein or in the applicable Company Order. If a Company
Order pursuant to Section 3.3 or 3.4 has been, or simultaneously is, delivered, any instructions by the Company with respect to
a Security in global form shall be in writing but need not be accompanied by or contained in an Officer’s Certificate and
need not be accompanied by an Opinion of Counsel.

 

Notwithstanding the provisions of Section
3.7, unless otherwise specified in or pursuant to this Indenture or any Security, payment of principal of, any premium and interest
on, and any Additional Amounts in respect of, any Security in temporary or permanent global form shall be made to the Person or
Persons specified therein.

 

Notwithstanding the provisions of Section
3.8 and except as provided in the preceding paragraph, the Company, the Trustee and any agent of the Company or the Trustee shall
treat as the Holder of such principal amount of Outstanding Securities represented by a global Security (i) in the case of a global
Security in registered form, the Holder of such global Security in registered form, or (ii) in the case of a global Security in
bearer form, the Person or Persons specified pursuant to Section 3.1.

All Securities of any one series and all
Coupons, if any, appertaining to Bearer Securities of such series shall be substantially identical except as to Currency of payments
due thereunder, denomination and the rate of interest thereon, or method of determining the rate of interest, if any, Maturity,
and the date from which interest, if any, shall accrue and except as may otherwise be provided by the Company in or pursuant to

in such Officer’s Certificate or supplemental indenture. All Securities of any one series need not be issued at the same
time and, unless otherwise so provided, a series may be reopened for issuances of additional Securities of such series or to establish
additional terms of such series of Securities.

 

If any of the terms of the Securities of
any series shall be established by action taken by or pursuant to a Board Resolution, the Board Resolution shall be delivered to

Section 3.2. Currency; Denominations.

 

Unless otherwise provided in or pursuant
to this Indenture, the principal of, any premium and interest on and any Additional Amounts with respect to the Securities shall
be payable in Dollars. Unless otherwise provided in or pursuant to this Indenture, Registered Securities denominated in Dollars
shall be issuable in registered form without Coupons in denominations of $1,000 and any integral multiple thereof, and the Bearer
Securities denominated in Dollars shall be issuable in the denomination of $5,000. Securities not denominated in Dollars shall
be issuable in such denominations as are established with respect to such Securities in or pursuant to this Indenture.

 

Section 3.3. Execution, Authentication, Delivery and Dating.

 

Securities shall be executed on behalf of
the Company by its Chairman of the Board, the President or any Vice President or the Treasurer or any Assistant Treasurer and attested
by its Secretary or one of its Assistant Secretaries. Coupons shall be executed on behalf of the Company by its Chairman of the
Board, the President or any Vice President, the Treasurer or any Assistant Treasurer, or the Secretary or any Assistant Secretary
of the Company. The signature of any of these officers on the Securities or any Coupons appertaining thereto may be manual or facsimile.

 

Securities and any Coupons appertaining
thereto bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall
bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication
and delivery of such Securities and Coupons or did not hold such offices at the date of original issuance of such Securities or
Coupons.

 

At any time and from time to time after
the execution and delivery of this Indenture, the Company may deliver Securities, together with any Coupons appertaining thereto,
executed by the Company, to the Trustee for authentication and, provided that the Board Resolution and Officer’s Certificate
or supplemental indenture or indentures with respect to such Securities referred to in Section 3.1 and a Company Order for the
authentication and delivery of such Securities have been delivered to the Trustee, the Trustee in accordance with the Company Order
and subject to the provisions hereof and of such Securities shall authenticate and deliver such Securities. In authenticating such
Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities and any Coupons appertaining
thereto, the Trustee shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall
be fully protected in relying upon,

 

(1) an Opinion of Counsel to the effect
that:

 

(a) the form or forms and terms
of such Securities and Coupons, if any, have been established in conformity with the provisions of this Indenture;

 

(b) all conditions precedent
to the authentication and delivery of such Securities and Coupons, if any, appertaining thereto, have been complied with and that
such Securities and Coupons, when completed by appropriate insertions, executed and attested by duly authorized officers of the
Company, delivered by duly authorized officers of

 

the Company to the Trustee for
authentication pursuant to this Indenture, and authenticated and delivered by the Trustee and issued by the Company in the manner
and subject to any conditions specified in such Opinion of Counsel, will constitute legally valid and binding obligations of the
Company, enforceable against the Company in accordance with their terms, except as enforcement thereof may be subject to or limited
by bankruptcy, insolvency, reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent transfer or other similar
laws relating to or affecting creditors’ rights generally, and subject to general principles of equity (regardless of whether
enforcement is sought in a proceeding in equity or at law) and will entitle the Holders thereof to the benefits of this Indenture;
such Opinion of Counsel need express no opinion as to the availability of equitable remedies;

 

    - 25 -

     

    

 

(c) all laws and requirements
in respect of the execution and delivery by the Company of such Securities and Coupons, if any, have been complied with; and

 

(d) this Indenture has been qualified
under the Trust Indenture Act; and

 

(2) an Officer’s Certificate stating
that, to the best knowledge of the Persons executing such certificate, all conditions precedent to the execution, authentication
and delivery of such Securities and Coupons, if any, appertaining thereto, have been complied with, and no event which is, or after
notice or lapse of time would become, an Event of Default with respect to any of the Securities shall have occurred and be continuing.

 

If all the Securities of any series are
not to be issued at one time, it shall not be necessary to deliver an Opinion of Counsel and an Officer’s Certificate at
the time of issuance of each Security, but such opinion and certificate, with appropriate modifications, shall be delivered at
or before the time of issuance of the first Security of such series. After any such first delivery, any separate written request
by an Authorized Officer of the Company or any person designated in writing by an Authorized Officer that the Trustee authenticate
and deliver Securities of such series for original issue will be deemed to be a certification by the Company that all conditions
precedent provided for in this Indenture relating to authentication and delivery of such Securities continue to have been complied
with and that no Event of Default with respect to any of the Securities has occurred or is continuing.

 

The Trustee shall not be required to authenticate
or to cause an Authenticating Agent to authenticate any Securities if the issue of such Securities pursuant to this Indenture will
affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which
is not reasonably acceptable to the Trustee or if the Trustee, being advised by counsel, determines that such action may not lawfully
be taken.

 

Each Registered Security shall be dated
the date of its authentication. Each Bearer Security and any Bearer Security in global form shall be dated as of the date specified
in or pursuant to this Indenture.

 

No Security or Coupon appertaining thereto
shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose, unless there appears on such Security
a certificate of authentication substantially in the form provided for in Section 2.2 or 6.12 executed by or on behalf of the Trustee
or by the Authenticating Agent by the manual signature of one of its authorized officers. Such certificate upon any Security shall
be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Except as
permitted by Section 3.6 or 3.7, the Trustee shall not authenticate and deliver any Bearer Security unless all Coupons appertaining
thereto then matured have been detached and cancelled.

 

Section 3.4. Temporary Securities.

 

Pending the preparation of definitive Securities,
the Company may execute and deliver to the Trustee and, upon Company Order, the Trustee shall authenticate and deliver, in the
manner provided in Section 3.3, temporary Securities in lieu thereof which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which
they are issued, in registered form or, if authorized in or pursuant to this Indenture, in bearer form with one or more Coupons
or without Coupons and with such appropriate insertions, omissions, substitutions and other variations as the officers of the Company
executing such Securities may determine, as conclusively evidenced by their execution of such Securities. Such temporary Securities
may be in global form.

 

    - 26 -

     

    

 

Except in the case of temporary Securities
in global form, which shall be exchanged in accordance with the provisions thereof, if temporary Securities are issued, the Company
shall cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities of
the same series and containing terms and provisions that are identical to those of any temporary Securities, such temporary Securities
shall be exchangeable for such definitive Securities upon surrender of such temporary Securities at an Office or Agency for such
Securities, without charge to any Holder thereof. Upon surrender for cancellation of any one or more temporary Securities (accompanied
by any unmatured Coupons appertaining thereto), the Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of authorized denominations of the same series and containing identical
terms and provisions; provided, however, that no definitive Bearer Security, except as provided in or pursuant to this Indenture,
shall be delivered in exchange for a temporary Registered Security; and provided, further, that a definitive Bearer Security shall
be delivered in exchange for a temporary Bearer Security only in compliance with the conditions set forth in or pursuant to this
Indenture. Unless otherwise provided in or pursuant to this Indenture with respect to a temporary global Security, until so exchanged
the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive
Securities of such series.

 

Section 3.5. Registration, Transfer and Exchange.

 

With respect to the Registered Securities
of each series, if any, the Company shall cause to be kept a register (each such register being herein sometimes referred to as
the “Security Register”) at an Office or Agency for such series in which, subject to such reasonable regulations as
it may prescribe, the Company shall provide for the registration of the Registered Securities of such series and of transfers of
the Registered Securities of such series. Such Office or Agency shall be the “Security Registrar” for that series of
Securities. Unless otherwise specified in or pursuant to this Indenture or the Securities, the Trustee shall be the initial Security
Registrar for each series of Securities. The Company shall have the right to remove and replace from time to time the Security
Registrar for any series of Securities; provided that no such removal or replacement shall be effective until a successor Security
Registrar with respect to such series of Securities shall have been appointed by the Company and shall have accepted such appointment
by the Company. In the event that the Trustee shall not be or shall cease to be Security Registrar with respect to a series of
Securities, it shall have the right to examine the Security Register for such series at all reasonable times. There shall be only
one Security Register for each series of Securities.

 

Upon surrender for registration of transfer
of any Registered Security of any series at any Office or Agency for such series, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or transferees, one or more new Registered Securities of the
same series denominated as authorized in or pursuant to this Indenture, of a like aggregate principal amount bearing a number not
contemporaneously outstanding and containing identical terms and provisions.

 

At the option of the Holder, Registered
Securities of any series may be exchanged for other Registered Securities of the same series containing identical terms and provisions,
in any authorized denominations, and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at
any Office or Agency for such series. Whenever any Registered Securities are so surrendered for exchange, the Company shall execute,
and the Trustee shall authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive.

 

    - 27 -

     

    

 

If provided in or pursuant to this Indenture,
with respect to Securities of any series, at the option of the Holder, Bearer Securities of such series may be exchanged for Registered
Securities of such series containing identical terms, denominated as authorized in or pursuant to this Indenture and in the same
aggregate principal amount, upon surrender of the Bearer Securities to be exchanged at any Office or Agency for such series, with
all unmatured Coupons and all matured Coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to
produce any such unmatured Coupon or Coupons or matured Coupon or Coupons in default, such exchange may be effected if the Bearer
Securities are accompanied by payment in funds acceptable to the Company and the Trustee in an amount equal to the face amount
of such missing Coupon or Coupons, or the surrender of such missing Coupon or Coupons may be waived by the Company and the Trustee
if there is furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless.
If thereafter the Holder of such Bearer Security shall surrender to any Paying Agent any such missing Coupon in respect of which
such a payment shall have been made, such Holder shall be entitled to receive the amount of such payment; provided, however, that,
except as otherwise provided in Section 10.2, interest represented by Coupons shall be payable only upon presentation and surrender
of those Coupons at an Office or Agency for such series located outside the United States. Notwithstanding the foregoing, in case
a Bearer Security of any series is surrendered at any such Office or Agency for such series in exchange for a Registered Security
of such series and like tenor after the close of business at such Office or Agency on (i) any Regular Record Date and before the
opening of business at such Office or Agency on the next succeeding Interest Payment Date, or (ii) any Special Record Date and
before the opening of business at such Office or Agency on the related date for payment of Defaulted Interest, such Bearer Security
shall be surrendered without the Coupon relating to such Interest Payment Date or proposed date of payment, as the case may be
(or, if such Coupon is so surrendered with such Bearer Security, such Coupon shall be returned to the Person so surrendering the
Bearer Security), and interest or Defaulted Interest, as the case may be, shall not be payable on such Interest Payment Date or
proposed date for payment, as the case may be, in respect of the Registered Security issued in exchange for such Bearer Security,
but shall be payable only to the Holder of such Coupon when due in accordance with the provisions of this Indenture.

 

If provided in or pursuant to this Indenture
with respect to Securities of any series, at the option of the Holder, Registered Securities of such series may be exchanged for
Bearer Securities upon such terms and conditions as may be provided in or pursuant to this Indenture with respect to such series.

 

Whenever any Securities are surrendered
for exchange as contemplated by the immediately preceding two paragraphs, the Company shall execute, and the Trustee shall authenticate
and deliver, the Securities which the Holder making the exchange is entitled to receive.

 

Notwithstanding the foregoing, except as
otherwise provided in or pursuant to this Indenture, any global Security shall be exchangeable for definitive Securities only if
(i) the Depository is at any time unwilling, unable or ineligible to continue as depository and a successor depository is not appointed
by the Company within 90 days of the date the Company is so informed in writing, (ii) the Company executes and delivers to the
Trustee a Company Order to the effect that such global Security shall be so exchangeable, or (iii) an Event of Default has occurred
and is continuing with respect to the Securities. If the beneficial owners of interests in a global Security are entitled to exchange
such interests for definitive Securities as the result of an event described in clause (i), (ii) or (iii) of the preceding sentence,
then without unnecessary delay but in any event not later than the earliest date on which such interests may be so exchanged, the
Company shall deliver to the Trustee definitive Securities in such form and denominations as are required by or pursuant to this
Indenture, and of the same series, containing identical terms and in aggregate principal amount equal to the principal amount of
such global Security, executed by the Company. On or after the earliest date on which such interests may be so exchanged, such
global Security shall be surrendered from time to time by the U.S. Depository or such other Depository as shall be specified in
the Company Order with respect thereto, and in accordance with instructions given to the Trustee and the U.S. Depository or such
other Depository, as the case may be (which instructions shall be in writing but need not be contained in or accompanied by an
Officer’s Certificate or be accompanied by an Opinion of Counsel), as shall be specified in the Company Order with respect
thereto to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or in part, for definitive Securities
as described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion
of such surrendered global Security, a like aggregate principal amount of definitive Securities of the same series of authorized
denominations and of like tenor as the portion of such global Security to be exchanged, which (unless such Securities are not issuable
both as Bearer Securities and as Registered Securities, in which case the definitive Securities exchanged for the global Security
shall be issuable only in the form in which the Securities are issuable, as provided in or pursuant to this Indenture) shall be
in the form of Bearer Securities or Registered Securities, or any combination thereof, as shall be specified by the beneficial
owner thereof, but subject to the satisfaction of any certification or other requirements to the issuance of Bearer Securities;
provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection
of Securities of the same series to be redeemed and ending on the relevant Redemption Date; and provided, further, that (unless
otherwise provided in or pursuant to this Indenture) no Bearer Security delivered in exchange for a portion of a global Security
shall be mailed or otherwise delivered to any location in the United States. Promptly following any such exchange in part, such
global Security shall be returned by the Trustee to such Depository or the U.S. Depository, as the case may be, or such other Depository
or U.S. Depository referred to above in accordance with the instructions of the Company referred to above. If a Registered Security
is issued in exchange for any portion of a global Security after the close of business at the Office or Agency for such Security
where such exchange occurs on or after (i) any Regular Record Date for such Security and before the opening of business at such
Office or Agency on the next succeeding Interest Payment Date, or (ii) any Special Record Date for such Security and before the
opening of business at such Office or Agency on the related proposed date for payment of interest or Defaulted Interest, as the
case may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect
of such Registered Security, but shall be payable on such Interest Payment Date or proposed date for payment, as the case may be,
only to the Person to whom interest in respect of such portion of such global Security shall be payable in accordance with the
provisions of this Indenture.

 

    - 28 -

     

    

 

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

 

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

 

No service charge shall be made for any
registration of transfer or exchange, or redemption of Securities, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge and any other expenses (including fees and expenses of the Trustee) that may be imposed in
connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.4, 9.5 or 11.7
not involving any transfer.

 

Except as otherwise provided in or pursuant
to this Indenture, the Company shall not be required (i) to issue, register the transfer of or exchange any Securities during a
period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of Securities of like tenor
and the same series under Section 11.3 and ending at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any Registered Security selected for redemption in whole or in part, except in the case of any Security
to be redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange any Bearer Security selected for redemption

Security of like tenor and the same series, provided that such Registered Security shall be immediately surrendered for redemption
with written instruction for payment consistent with the provisions of this Indenture or (iv) to issue, register the transfer of
or exchange any Security which, in accordance with its terms, has been surrendered for repayment at the option of the Holder, except

Section 3.6. Mutilated, Destroyed, Lost and Stolen Securities.

 

If any mutilated Security or a Security
with a mutilated Coupon appertaining to it is surrendered to the Trustee, subject to the provisions of this Section 3.6, the Company
shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount and bearing a number not contemporaneously outstanding, with Coupons appertaining
thereto corresponding to the Coupons, if any, appertaining to the surrendered Security.

 

If there be delivered to the Company and
the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security or Coupon, and (ii) such security
or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of
notice to the Company or the Trustee that such Security or Coupon has been acquired by a bona fide purchaser, the Company shall
execute and, upon the Company’s request the Trustee shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Security or in exchange for the Security to which a destroyed, lost or stolen Coupon appertains
with all appurtenant Coupons not destroyed, lost or stolen, a new Security of the same series containing identical terms and of
like principal amount and bearing a number not contemporaneously outstanding, with Coupons appertaining thereto corresponding to
the Coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or
stolen Coupon appertains.

 

Notwithstanding the foregoing provisions
of this Section 3.6, in case any mutilated, destroyed, lost or stolen Security or Coupon has become or is about to become due and
payable, the Company in its discretion may, instead of issuing a new Security, pay such Security or Coupon; provided, however,
that payment of principal of, any premium or interest on or any Additional Amounts with respect to any Bearer Securities shall,
except as otherwise provided in Section 10.2, be payable only at an Office or Agency for such Securities located outside the United
States and, unless otherwise provided in or pursuant to this Indenture, any interest on Bearer Securities and any Additional Amounts
with respect to such interest shall be payable only upon presentation and surrender of the Coupons appertaining thereto.

 

Upon the issuance of any new Security under
this Section 3.6, the Company 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.

 

Every new Security, with any Coupons appertaining
thereto issued pursuant to this Section 3.6 in lieu of any destroyed, lost or stolen Security, or in exchange for a Security to
which a destroyed, lost or stolen Coupon appertains shall constitute a separate obligation of the Company, whether or not the destroyed,
lost or stolen Security and Coupons appertaining thereto or the destroyed, lost or stolen Coupon shall be at any time enforceable
by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities
of such series and any Coupons, if any, duly issued hereunder.

 

    - 30 -

     

    

 

The provisions of this Section 3.6, as amended
or supplemented pursuant to this Indenture with respect to particular Securities or generally, shall be 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 or Coupons.

 

Section 3.7. Payment of Interest and Certain
Additional Amounts; Rights to Interest and Certain Additional Amounts Preserved.

 

Unless otherwise provided in or pursuant
to this Indenture, any interest on and any Additional Amounts with respect to any Registered Security which shall be payable, and
are punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Security
(or one or more Predecessor Securities) is registered as of the close of business on the Regular Record Date for such interest.

 

Unless otherwise provided in or pursuant
to this Indenture, any interest on and any Additional Amounts with respect to any Registered Security which shall be payable, but
shall not be punctually paid or duly provided for, on any Interest Payment Date for such Registered Security (herein called “Defaulted
Interest”) shall forthwith cease to be payable to the Holder thereof on the relevant Regular Record Date by virtue of having
been such Holder; and such Defaulted Interest may be paid by the Company, at its election, as provided in clause (1) or (2) below:

 

(1) The Company may elect to make payment
of any Defaulted Interest to the Person in whose name such Registered Security (or a Predecessor Security thereof) shall be registered
at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed by the Company
in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid
on such Registered Security, the Special Record Date therefor and the date of the proposed payment, and at the same time the Company
shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment,
such money when so deposited to be held in trust for the benefit of the Person entitled to such Defaulted Interest as provided
in this clause (1). The Special Record Date for the payment of such Defaulted Interest shall be not more than 15 days and not less
than 10 days prior to the date of the proposed payment and not less than 10 days after notification to the Trustee of the proposed
payment. The Trustee shall, in the name and at the expense of the Company, cause notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to the Holder of such Registered Security
(or a Predecessor Security thereof) at his address as it appears in the Security Register not less than 10 days prior to such Special
Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published
at least once in an Authorized Newspaper of general circulation in the Borough of Manhattan, The City of New York, but such publication
shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Person
in whose name such Registered Security (or a Predecessor Security thereof) shall be registered at the close of business on such
Special Record Date and shall no longer be payable pursuant to the following clause (2).

 

(2) The Company may make payment of any
Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Security
may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of
the proposed payment pursuant to this clause (2), such payment shall be deemed practicable by the Trustee.

 

    - 31 -

     

    

 

Unless otherwise provided in or pursuant
to this Indenture or the Securities of any particular series pursuant to the provisions of this Indenture, at the option of the
Company, interest on Registered Securities that bear interest may be paid by mailing a check to the address of the Person entitled
thereto as such address shall appear in the Security Register or by transfer to an account maintained by the payee with a bank
located in the United States.

 

Subject to the foregoing provisions of this
Section and Section 3.5, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in
lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other
Security.

 

In the case of any Registered Security of
any series that is convertible into other securities of the Company or exchangeable for securities of another issuer, which Registered
Security is converted or exchanged after any Regular Record Date and on or prior to the next succeeding Interest Payment Date (other
than any Registered Security with respect to which the Stated Maturity is prior to such Interest Payment Date), interest with respect
to which the Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such
conversion or exchange, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in
whose name that Registered Security (or one or more predecessor Registered Securities) is registered at the close of business on
such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Registered
Security which is converted or exchanged, interest with respect to which the Stated Maturity is after the date of conversion or
exchange of such Registered Security shall not be payable.

 

Section 3.8. Persons Deemed Owners.

 

Prior to due presentment of a Registered
Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person
in whose name such Registered Security is registered in the Security Register as the owner of such Registered Security for the
purpose of receiving payment of principal of, any premium and (subject to Sections 3.5 and 3.7) interest on and any Additional
Amounts with respect to such Registered Security and for all other purposes whatsoever, whether or not any payment with respect
to such Registered Security shall be overdue, and none of the Company, the Trustee or any agent of the Company or the Trustee shall
be affected by notice to the contrary.

 

The Company, the Trustee and any agent of
the Company or the Trustee may treat the bearer of any Bearer Security or the bearer of any Coupon as the absolute owner of such
Security or Coupon for the purpose of receiving payment thereof or on account thereof and for all other purposes whatsoever, whether
or not any payment with respect to such Security or Coupon shall be overdue, and none of the Company, the Trustee or any agent
of the Company or the Trustee shall be affected by notice to the contrary.

 

No Holder of any beneficial interest in
any global Security held on its behalf by a Depository shall have any rights under this Indenture with respect to such global Security,
and such Depository may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the owner of such
global Security for all purposes whatsoever. None of the Company, the Trustee, any Paying Agent or the Security Registrar will
have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership
interests of a global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Section 3.9. Cancellation.

 

All Securities and Coupons surrendered for
payment, redemption, registration of transfer, exchange or conversion or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities and Coupons, as well as
Securities and Coupons surrendered directly to the Trustee for any such purpose, shall be cancelled promptly by the Trustee. The
Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be cancelled promptly by the
Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by or pursuant to this Indenture. All cancelled Securities and Coupons held by the Trustee shall
be destroyed by the Trustee, unless by a Company Order the Company directs their return to it.

 

Section 3.10. Computation of Interest.

 

Except as otherwise provided in or pursuant
to this Indenture or in any Security, interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day
months.

 

ARTICLE 4.

Section 4.1. Satisfaction and Discharge.

 

Upon the direction of the Company by a Company
Order, this Indenture shall cease to be of further effect[, and the provisions of Article 16 shall cease to be effective,] with
respect to any series of Securities specified in such Company Order and any Coupons appertaining thereto, and the Trustee, on receipt
of a Company Order, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture as to such series, when

 

(1) either

 

(a) all Securities of such series
theretofore authenticated and delivered and all Coupons appertaining thereto (other than (i) Coupons appertaining to Bearer Securities
of such series surrendered in exchange for Registered Securities of such series and maturing after such exchange whose surrender

(b) all Securities of such series
and, in the case of (i) or (ii) below, any Coupons appertaining thereto not theretofore delivered to the Trustee for cancellation,
(i) have become due and payable, or (ii) will become due and payable at their Stated Maturity within one year, or (iii) if redeemable
at the option of the Company, are to be called for redemption within one year under arrangements satisfactory to the Trustee for
the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company, in the case
of (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose,

as the case may be;

 

    - 33 -

     

    

 

(2) the Company has paid or caused to be
paid all other sums payable hereunder by the Company with respect to the Outstanding Securities of such series and any Coupons
appertaining thereto; and

 

(3) the Company has delivered to the Trustee
an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating
to the satisfaction and discharge of this Indenture as to such series have been complied with.

 

In the event there are Securities of two
or more series hereunder, the Trustee shall be required to execute an instrument acknowledging satisfaction and discharge of this
Indenture only if requested to do so with respect to Securities of such series as to which it is Trustee and if the other conditions
thereto are met.

 

Notwithstanding the satisfaction and discharge
of this Indenture with respect to any series of Securities, the obligations of the Company to the Trustee under Section 6.7 and,
if money shall have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the obligations of

to the payment of Additional Amounts, if any, with respect to such Securities as contemplated by Section 10.4 (but only to the
extent that the Additional Amounts payable with respect to such Securities exceed the amount deposited in respect of such Additional
Amounts pursuant to Section 4.1(1)(b)), and with respect to any rights to convert or exchange such Securities into securities of
the Company or another issuer shall survive.

 

Section 4.2. Defeasance and Covenant Defeasance.

 

(1) Unless pursuant to Section 3.1, either
or both of (i) defeasance of the Securities of or within a series under clause (2) of this Section 4.2 shall not be applicable
with respect to the Securities of such series or (ii) covenant defeasance of the Securities of or within a series under clause
(3) of this Section 4.2 shall not be applicable with respect to the Securities of such series, then such provisions, together with
the other provisions of this Section 4.2 (with such modifications thereto as may be specified pursuant to Section 3.1 with respect
to any Securities), shall be applicable to such Securities and any Coupons appertaining thereto, and the Company may at its option
by Board Resolution, at any time, with respect to such Securities and any Coupons appertaining thereto, elect to have Section 4.2(2)
or Section 4.2(3) be applied to such Outstanding Securities and any Coupons appertaining thereto upon compliance with the conditions
set forth below in this Section 4.2.

 

(2) Upon the Company’s exercise
of the above option applicable to this Section 4.2(2) with respect to any Securities of or within a series, the Company shall
be deemed to have been discharged from its obligations[, and the provisions of Article 16 shall cease to be effective,] with
respect to such Outstanding Securities and any Coupons appertaining thereto on the date the conditions set forth in clause
(4) of this Section 4.2 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that
the Company shall be deemed to have paid and discharged the entire Indebtedness represented by such Outstanding Securities
and any Coupons appertaining thereto, which shall thereafter be deemed to be “Outstanding”
only for the purposes of clause (5) of this Section 4.2 and the other Sections of this Indenture referred to in clauses (i) and
(ii) below, and to have satisfied all of its other obligations under such Securities and any Coupons appertaining thereto, and
this Indenture insofar as such Securities and any Coupons appertaining thereto are concerned (and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise
terminated or discharged hereunder: (i) the rights of Holders of such Outstanding Securities and any Coupons appertaining thereto
to receive, solely from the trust fund described in clause (4) of this Section 4.2 and as more fully set forth in such clause,
payments in respect of the principal of (and premium, if any) and interest, if any, on, and Additional Amounts, if any, with respect
to, such Securities and any Coupons appertaining thereto when such payments are due, and any rights of such Holder to convert such
Securities into other securities of the Company or exchange such Securities for securities of another issuer, (ii) the obligations
of the Company and the Trustee with respect to such Securities under Sections 3.5, 3.6, 10.2 and 10.3 and with respect to the payment
of Additional Amounts, if any, on such Securities as contemplated by Section 10.4 (but only to the extent that the Additional Amounts
payable with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to Section 4.2(4)(a)
below), and with respect to any rights to convert such Securities into other securities of the Company or exchange such Securities
for securities of another issuer, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this
Section 4.2. The Company may exercise its option under this Section 4.2(2) notwithstanding the prior exercise of its option under
clause (3) of this Section 4.2 with respect to such Securities and any Coupons appertaining thereto.

 

    - 34 -

     

    

 

(3) Upon the Company’s exercise of
the option to have this Section 4.2(3) apply with respect to any Securities of or within a series, the Company shall be released
from its obligations under, to the extent specified pursuant to Section 3.1(19), any covenant applicable to such Securities[, and
the provisions of Article 16 shall cease to be effective as it relates to the aforementioned obligations and covenants,] with respect
to such Outstanding Securities and any Coupons appertaining thereto, on and after the date the conditions set forth in clause (4)
of this Section 4.2 are satisfied (hereinafter, “covenant defeasance”), and such Securities and any Coupons appertaining
thereto shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or declaration
or Act of Holders (and the consequences of any thereof) in connection with any such obligation or covenant, but shall continue
to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance means that,
with respect to such Outstanding Securities and any Coupons appertaining thereto, the Company may omit to comply with, and shall
have no liability in respect of, any term, condition or limitation set forth in any such Section or such other covenant, [or Article,]
whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant[, or Article,]
or by reason of reference in any such Section or such other covenant[, or Article,] to any other provision herein or in any other
document and such omission to comply shall not constitute a default or an Event of Default under Section 5.1(4) or 5.1(7) or otherwise,
as the case may be, but, except as specified above, the remainder of this Indenture and such Securities and Coupons appertaining
thereto shall be unaffected thereby.

 

(4) The following shall be the conditions
to application of clause (2) or (3) of this Section 4.2 to any Outstanding Securities of or within a series and any Coupons appertaining
thereto:

 

(a) The Company shall irrevocably
have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 6.8 who shall
agree to comply with the provisions of this Section 4.2 applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities
and any Coupons appertaining thereto, (1) an amount in Dollars or in such Foreign Currency in which such Securities and any Coupons
appertaining thereto are then specified as payable at Stated Maturity, or (2) Government Obligations applicable to such Securities
and Coupons appertaining thereto (determined on the basis of the Currency in which such Securities and Coupons appertaining thereto
are then specified as payable at Stated Maturity) which through the scheduled payment of principal and interest in respect thereof
in accordance with their terms will provide, not later than one day before the due date of any payment of principal of (and premium,
if any) and interest, if any, on such Securities and any Coupons appertaining thereto, money in an amount, or (3) a combination
thereof, in any case, in an amount, sufficient, without consideration of any reinvestment of such principal and interest, in the
opinion of a nationally recognized firm of 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 (or other qualifying trustee) to pay and discharge,
(y) the principal of (and premium, if any) and interest, if any, on such Outstanding Securities and any Coupons appertaining thereto
at the Stated Maturity of such principal or installment of principal or premium or interest and (z) any mandatory sinking fund
payments or analogous payments applicable to such Outstanding Securities and any Coupons appertaining thereto on the days on which
such payments are due and payable in accordance with the terms of this Indenture and of such Securities and any Coupons appertaining
thereto.

 

    - 35 -

     

    

 

(b) Such defeasance or covenant
defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or any other material agreement
or instrument to which the Company is a party or by which it is bound.

 

(c) No Event of Default or event
which with notice or lapse of time or both would become an Event of Default with respect to such Securities and any Coupons appertaining
thereto shall have occurred and be continuing on the date of such deposit and, with respect to defeasance only, at any time during
the period ending on the 123rd day after the date of such deposit (it being understood that this condition shall not be deemed
satisfied until the expiration of such period).

 

(d) In the case of an election
under clause (2) of this Section 4.2, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (i) the
Company has received from the Internal Revenue Service a letter ruling, or there has been published by the Internal Revenue Service
a Revenue Ruling, or (ii) since the date of execution of this Indenture, there has been a change in the applicable Federal income
tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of such Outstanding
Securities and any Coupons appertaining thereto 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.

 

(e) In the case of an election
under clause (3) of this Section 4.2, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that
the Holders of such Outstanding Securities and any Coupons appertaining thereto 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.

 

(f) The Company shall have delivered
to the Trustee an Opinion of Counsel to the effect that, after the 123rd day after the date of deposit, all money and Government
Obligations (or other property as may be provided pursuant to Section 3.1) (including the proceeds thereof) deposited or caused
to be deposited with the Trustee (or other qualifying trustee) pursuant to this clause (4) to be held in trust will not be subject
to any case or proceeding (whether voluntary or involuntary) in respect of the Company under any Federal or State bankruptcy, insolvency,
reorganization or other similar law, or any decree or order for relief in respect of the Company issued in connection therewith.

(g) [At the time of the deposit,
(i) no default in the payment of any principal of, premium, if any, or interest on any Senior Indebtedness shall have occurred
and be continuing, (ii) no event of default with respect to any Senior Indebtedness shall have resulted in such Senior Indebtedness
becoming, and continuing to be, due and payable prior to the date on which it would otherwise have become due and payable (unless
payment of such Senior Indebtedness has been made or duly provided for), and (iii) no other event of default with respect to any
Senior Indebtedness shall have occurred and be continuing permitting (after notice or lapse of time or both) the holders of such
Senior Indebtedness (or a trustee on behalf of such holders) to declare such Senior Indebtedness due and payable prior to the date
on which it would otherwise have become due and payable.]

 

(h) The Company shall have delivered
to the Trustee an Officer’s Certificate and the Company shall have delivered to the Trustee an Opinion of Counsel, each stating
that all conditions precedent to the defeasance or covenant defeasance under clause (2) or (3) of this Section 4.2 (as the case
may be) have been complied with.

 

(i) Notwithstanding any other
provisions of this Section 4.2(4), such defeasance or covenant defeasance shall be effected in compliance with any additional or
substitute terms, conditions or limitations which may be imposed on the Company in connection therewith pursuant to Section 3.1.

 

(5) Unless otherwise specified in or pursuant
to this Indenture or any Security, if, after a deposit referred to in Section 4.2(4)(a) has been made, (a) the Holder of a Security
in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 3.1 or the terms of such Security
to receive payment in a Currency other than that in which the deposit pursuant to Section 4.2(4)(a) has been made in respect of
such Security, or (b) a Conversion Event occurs in respect of the Foreign Currency in which the deposit pursuant to Section 4.2(4)(a)
has been made, the indebtedness represented by such Security and any Coupons appertaining thereto shall be deemed to have been,
and will be, fully discharged and satisfied through the payment of the principal of (and premium, if any), and interest, if any,
on, and Additional Amounts, if any, with respect to, such Security as the same becomes due out of the proceeds yielded by converting
(from time to time as specified below in the case of any such election) the amount or other property deposited in respect of such
Security into the Currency in which such Security becomes payable as a result of such election or Conversion Event based on (x)
in the case of payments made pursuant to clause (a) above, the applicable market exchange rate for such Currency in effect on the
second Business Day prior to each payment date, or (y) with respect to a Conversion Event, the applicable market exchange rate
for such Foreign Currency in effect (as nearly as feasible) at the time of the Conversion Event.

 

The Company shall pay and indemnify the
Trustee (or other qualifying trustee, collectively for purposes of this Section 4.2(5) and Section 4.3, the “Trustee”)
against any tax, fee or other charge, imposed on or assessed against the Government Obligations deposited pursuant to this Section
4.2 or the principal or 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 such Outstanding Securities and any Coupons appertaining thereto.

 

Anything in this Section 4.2 to the contrary
notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request, any money or Government
Obligations (or other property and any proceeds therefrom) held by it as provided in clause (4) of this Section 4.2 which, in the
opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered
to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect a defeasance or covenant
defeasance, as applicable, in accordance with this Section 4.2.

Section 4.3. Application of Trust Money.

 

Subject to the provisions of the last paragraph
of Section 10.3, all money and Government Obligations (or other property as may be provided pursuant to Section 3.1) (including
the proceeds thereof) deposited with the Trustee pursuant to Section 4.1 or 4.2 in respect of any Outstanding Securities of any
series and any Coupons appertaining thereto shall be held in trust and applied by the Trustee, in accordance with the provisions
of such Securities and any Coupons appertaining thereto and this Indenture, to the payment, either directly or through any Paying

any Coupons appertaining thereto of all sums due and to become due thereon in respect of principal (and premium, if any) and interest
and Additional Amounts, if any; but such money and Government Obligations need not be segregated from other funds except to the
extent required by law. [Money and Government Obligations so held in trust shall not be subject to the provisions of Article 16
except to the extent set forth in Section 16.1.]

 

Section 4.4. Reinstatement.

 

If the Trustee or any Paying Agent is unable
to apply any money in accordance with this Article with respect to any Securities by reason of any order or judgment of any court
or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture
and such Securities from which the Company has been discharged or released pursuant to Section 4.2(2) or 4.2(3) shall be revived
and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the
Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 4.3 with respect to such Securities in
accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest
on any such Securities following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any)
of the Holders of such Securities to receive such payment from the money so held in trust.

obtained by the Trustee as hereinafter in this Article provided, the Holders of not less than a majority in principal amount of
the Outstanding Securities of such series, by written notice to the Company and the Trustee, may rescind and annul such declaration

Section 5.3. Collection of Indebtedness and Suits for Enforcement
by Trustee.

 

The Company covenants that if

 

(1) default is made in the payment of any
installment of interest on or any Additional Amounts with respect to any Security or any Coupon appertaining thereto when such
interest or Additional Amounts shall have become due and payable and such default continues for a period of 30 days, or

 

(2) default is made in the payment of
the principal of or any premium on any Security or any Additional Amounts with respect thereto at their Maturity, the Company
shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities and any Coupons
appertaining thereto, the whole amount of money then due and payable with respect to such Securities and any Coupons
appertaining thereto, with interest upon the overdue principal, any premium and, to the extent that payment of such interest
shall be legally enforceable, upon any overdue installments of interest and Additional Amounts at the rate or rates borne by
or provided for in such Securities, and, in addition thereto, such further amount of money as shall be sufficient to cover

is required to pay the Trustee pursuant to the preceding paragraph forthwith upon the demand of the Trustee, the Trustee, in its
own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the money so due and unpaid,
and 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 any Coupons appertaining thereto and collect the monies adjudged or decreed to be payable in the manner
provided by law out of the property of the Company or any other obligor upon such Securities and any Coupons appertaining thereto,
wherever situated.

 

If an Event of Default with respect to Securities
of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights
of the Holders of Securities of such series and any Coupons appertaining thereto 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 such Securities or in aid of the exercise of any power granted herein or therein, or to enforce
any other proper remedy.

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 any overdue principal, premium, interest or Additional Amounts) shall be entitled and empowered, by intervention in such proceeding
or otherwise,

(2) to collect and receive any monies 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 of Securities
or any Coupons 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 of Securities or any Coupons, to pay to the Trustee any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section
6.7.

of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, shall be for the ratable
benefit of each and every Holder of the Securities or Coupons in respect of which such judgment has been recovered.

Amounts, respectively;

 

THIRD: The balance, if any, to the Person

(5) no direction inconsistent with such
written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the
Outstanding Securities of such 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 or any Security to affect, disturb or prejudice
the rights of any other such Holders or Holders of Securities of any other series, or to obtain or to seek to obtain priority or
preference over any other 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.

Security or payment of such Coupon, as the case may be, on the respective Stated Maturity or Maturities therefor specified in such
Security or Coupon (or, in the case of redemption, on the Redemption Date or, in the case of repayment at the option of such Holder

such payment, and such right shall not be impaired without the consent of such Holder.

 

Section 5.9. Restoration of Rights and Remedies.

 

If the Trustee or any Holder of a Security

Except as otherwise provided with respect
to the replacement or payment of mutilated, destroyed, lost or stolen Securities or Coupons in the last paragraph of Section 3.6,
no right or remedy herein conferred upon or reserved to the Trustee or to each and every Holder of a Security or a Coupon is intended
to be exclusive of any other right or remedy, and every right and remedy, to the extent permitted by law, shall 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, to the extent permitted by law, prevent the
concurrent assertion or employment of any other appropriate right or remedy.

 

Section 5.11. Delay or Omission Not Waiver.

 

No delay or omission of the Trustee or of
any Holder of any Security or Coupon 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 any Holder of a Security or a Coupon may be exercised from time to time, and as often as
may be deemed expedient, by the Trustee or by such Holder, as the case may be.

(1) such direction shall not be in conflict
with any rule of law or with this Indenture or with the Securities of such series,

deemed proper by the Trustee which is not inconsistent with such direction, and

 

(3) such direction is not unduly prejudicial

The Holders of not less than a majority
in principal amount of the Outstanding Securities of any series on behalf of the Holders of all the Securities of such series and

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

 

Section 5.15. 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 or omitted by it as Trustee, the filing by any party litigant in such suit of any undertaking to pay the costs of such suit,
and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party
litigant in such suit having due regard to the merits and good faith of the claims or defenses made by such party litigant; but
the provisions of this Section 5.15 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder,
or group of Holders, holding in the aggregate more than 10% in principal amount of Outstanding Securities of any series, or to

trust business of the Trustee shall be the successor of the Trustee hereunder, without the execution or filing of any paper or
any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated but not delivered

Section 6.12. Appointment of Authenticating Agent.

 

The Trustee may appoint one or more Authenticating

authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating
Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent.

or consolidation to which such Authenticating Agent shall be a party, or any Corporation succeeding by sale or otherwise to all
or substantially all of the corporate agency or corporate trust business of an Authenticating Agent, shall be the successor of
such Authenticating Agent hereunder, provided such Corporation shall be otherwise eligible under this Section, without the execution
or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

 

An Authenticating Agent may resign at any
time by giving written notice thereof to the Trustee and the Company. The Trustee may at any time terminate the agency of an Authenticating
Agent by giving written notice thereof to such Authenticating Agent and the Company. Upon receiving such a notice of resignation
or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and
shall (i) mail written notice of such appointment by first-class mail, postage prepaid, to all Holders of Registered Securities,
if any, of the series with respect to which such Authenticating Agent shall serve, as their names and addresses appear in the Security
Register, and (ii) if Securities of the series are issued as Bearer Securities, publish notice of such appointment at least once
in an Authorized Newspaper in the place where such successor Authenticating Agent has its principal office if such office is located
outside the United States. Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested
with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating
Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

 

The Company agrees to pay each Authenticating
Agent from time to time reasonable compensation for its services under this Section. If the Trustee makes such payments, it shall
be entitled to be reimbursed for such payments, subject to the provisions of Section 6.7.

 

The provisions of Sections 3.8, 6.4 and
6.5 shall be applicable to each Authenticating Agent.

 

If an Authenticating Agent is appointed
with respect to one or more series of Securities pursuant to this Section, the Securities of such series may have endorsed thereon,
in addition to or in lieu of the Trustee’s certificate of authentication, an alternate certificate of authentication in substantially
the following form:

 

This is one of the Securities of the series
designated herein referred to in the within-mentioned Indenture.

 

	Dated:	 	as
    Trustee
	 	 	 
	 	By:	
	 		as Authenticating
    Agent
	 	 	 
	 	By:	 
	 	 	Authorized
    Officer

 

    - 52 -

     

    

 

If all of the Securities of any series may
not be originally issued at one time, and if the Trustee does not have an office capable of authenticating Securities upon original
issuance located in a Place of Payment where the Company wishes to have Securities of such series authenticated upon original issuance,
the Trustee, if so requested in writing

 

(which writing need not be accompanied by
or contained in an Officer’s Certificate by the Company), shall appoint in accordance with this Section an Authenticating
Agent having an office in a Place of Payment designated by the Company with respect to such series of Securities.

COVENANTS

 

Section 10.1. Payment of Principal, Any Premium, Interest
and Additional Amounts.

 

The Company covenants and agrees for the
benefit of the Holders of the Securities of each series that it will duly and punctually pay the principal of, any premium and
interest on and any Additional Amounts with respect to the Securities of such series in accordance with the terms thereof, any
Coupons appertaining thereto and this Indenture. Any interest due on any Bearer Security on or before the Maturity thereof, and
any Additional Amounts payable with respect to such interest, shall be payable only upon presentation and surrender of the Coupons
appertaining thereto for such interest as they severally mature.

 

Section 10.2. Maintenance of Office or Agency.

 

The Company shall maintain in each Place
of Payment for any series of Securities an Office or Agency where Securities of such series (but not Bearer Securities, except
as otherwise provided below, unless such Place of Payment is located outside the United States) may be presented or surrendered
for payment, where Securities of such series may be surrendered for registration of transfer or exchange, where Securities of such
series that are convertible or exchangeable may be surrendered for conversion or exchange, and where notices and demands to or
upon the Company in respect of the Securities of such series relating thereto and this Indenture may be served. If Securities of
a series are issuable as Bearer Securities, the Company shall maintain, subject to any laws or regulations applicable thereto,
an Office or Agency in a Place of Payment for such series which is located outside the United States where Securities of such series
and any Coupons appertaining thereto may be presented and surrendered for payment; provided, however, that if the Securities of
such series are listed on The Stock Exchange of the United Kingdom and the Republic of Ireland or the Luxembourg Stock Exchange
or any other stock exchange located outside the United States and such stock exchange shall so require, the Company shall maintain
a Paying Agent in London, Luxembourg or any other required city located outside the United States, as the case may be, so long
as the Securities of such series are listed on such exchange. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such Office or Agency. If at any time the Company shall fail to maintain any such
required Office or Agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices
and demands may be made or served at the Corporate Trust Office of the Trustee, except that Bearer Securities of such series and
any Coupons appertaining thereto may be presented and surrendered for payment at the place specified for the purpose with respect
to such Securities as provided in or pursuant to this Indenture, and the Company hereby appoints the Trustee as its agent to receive
all such presentations, surrenders, notices and demands.

 

    - 58 -

     

    

 

Except as otherwise provided in or pursuant
to this Indenture, no payment of principal, premium, interest or Additional Amounts with respect to Bearer Securities shall be
made at any Office or Agency in the United States or by check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, if amounts owing with respect to any Bearer Securities
shall be payable in Dollars, payment of principal of, any premium or interest on and any Additional Amounts with respect to any
such Security may be made at the Corporate Trust Office of the Trustee or any Office or Agency designated by the Company in the
Borough of Manhattan, The City of New York, if (but only if) payment of the full amount of such principal, premium, interest or
Additional Amounts at all offices outside the United States maintained for such purpose by the Company in accordance with this
Indenture is illegal or effectively precluded by exchange controls or other similar restrictions.

 

The Company may also from time to time designate
one or more other Offices or Agencies where the Securities of one or more series may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall
in any manner relieve the Company of its obligation to maintain an Office or Agency in each Place of Payment for Securities of
any series for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other Office or Agency. Unless otherwise provided in or pursuant to this Indenture,
the Company hereby designates as the Place of Payment for each series of Securities the Borough of Manhattan, The City of New York,
and initially appoints the Corporate Trust Office of the Trustee as the Office or Agency of the Company in the Borough of Manhattan,
The City of New York for such purpose. The Company may subsequently appoint a different Office or Agency in the Borough of Manhattan,
The City of New York for the Securities of any series.

 

Unless otherwise specified with respect
to any Securities pursuant to Section 3.1, if and so long as the Securities of any series (i) are denominated in a Foreign Currency
or (ii) may be payable in a Foreign Currency, or so long as it is required under any other provision of this Indenture, then the
Company will maintain with respect to each such series of Securities, or as so required, at least one exchange rate agent.

 

Section 10.3. Money for Securities Payments to be Held
in Trust.

 

If the Company shall at any time act as
its own Paying Agent with respect to any series of Securities, it shall, on or before each due date of the principal of, any premium
or interest on or Additional Amounts with respect to any of the Securities of such series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum in the currency or currencies, currency unit or units or composite currency or currencies
in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.1 for the Securities of
such series) sufficient to pay the principal or any premium, interest or Additional Amounts so becoming due until such sums shall
be paid to such Persons or otherwise disposed of as herein provided, and shall promptly notify the Trustee of its action or failure
so to act.

 

    - 59 -

     

    

 

 

Whenever the
Company shall have one or more Paying Agents for any series of Securities, it shall, on or prior to each due date of the principal
of, any premium or interest on or any Additional Amounts with respect to any Securities of such series, deposit with any Paying
Agent a sum (in the currency or currencies, currency unit or units or composite currency or currencies described in the preceding
paragraph) sufficient to pay the principal or any premium, interest or Additional Amounts so becoming due, such sum to be held
in trust for the benefit of the Persons entitled thereto, and (unless such Paying Agent is the Trustee) the Company will promptly
notify the Trustee of its action or failure so to act.

 

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

 

(1) hold all
sums held by it for the payment of the principal of, any premium or interest on or any Additional Amounts with respect to Securities
of such series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise
disposed of as provided in or pursuant to this Indenture;

 

(2) give the
Trustee notice of any default by the Company (or any other obligor upon the Securities of such series) in the making of any payment
of principal, any premium or interest on or any Additional Amounts with respect to the Securities of such series; and

 

(3) at any
time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums
so held in trust by such Paying Agent.

 

The Company
may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay,
or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent,
such sums to be held by the Trustee upon the same terms as those upon which such sums were held by the Company or such Paying
Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability
with respect to such sums.

 

Except as
otherwise provided herein or pursuant hereto, 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, any premium or interest on or any Additional Amounts with respect to any Security
of any series or any Coupon appertaining thereto and remaining unclaimed for two years after such principal or any such premium
or interest or any such Additional Amounts shall have become due and payable shall be paid to the Company on Company Request,
or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security or any Coupon appertaining
thereto shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, 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 repayment, may
at the expense of the Company cause to be published once, in an Authorized Newspaper in each Place of Payment for such series
or to be mailed to Holders of Registered Securities of such series, or both, 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 or mailing nor shall it
be later than two years after such principal and any premium or interest or Additional Amounts shall have become due and payable,
any unclaimed balance of such money then remaining will be repaid to the Company.

Section 10.4. Additional
Amounts.

 

If any Securities
of a series provide for the payment of Additional Amounts, the Company agrees to pay to the Holder of any such Security or any
Coupon appertaining thereto Additional Amounts as provided in or pursuant to this Indenture or such Securities. Whenever in this
Indenture there is mentioned, in any context, the payment of the principal of or any premium or interest on, or in respect of,
any Security of any series or any Coupon or the net proceeds received on the sale or exchange of any Security of any series, such
mention shall be deemed to include mention of the payment of Additional Amounts provided by the terms of such series established
hereby or pursuant hereto to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof
pursuant to such terms, and express mention of the payment of Additional Amounts (if applicable) in any provision hereof shall
not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made.

 

Except as
otherwise provided in or pursuant to this Indenture or the Securities of the applicable series, if the Securities of a series
provide for the payment of Additional Amounts, at least 10 days prior to the first Interest Payment Date with respect to such
series of Securities (or if the Securities of such series shall not bear interest prior to Maturity, the first day on which a
payment of principal is made), and at least 10 days prior to each date of payment of principal or interest if there has been any
change with respect to the matters set forth in the below-mentioned Officer’s Certificate, the Company shall furnish to
the Trustee and the principal Paying Agent or Paying Agents, if other than the Trustee, an Officer’s Certificate instructing
the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and premium, if any, or interest on the
Securities of such series shall be made to Holders of Securities of such series or the Coupons appertaining thereto who are United
States Aliens without withholding for or on account of any tax, assessment or other governmental charge described in the Securities
of such series. If any such withholding shall be required, then such Officer’s Certificate shall specify by country the
amount, if any, required to be withheld on such payments to such Holders of Securities or Coupons, and the Company agrees to pay
to the Trustee or such Paying Agent the Additional Amounts required by the terms of such Securities. The Company covenants to
indemnify the Trustee and any Paying Agent for, and to hold them harmless against, any loss, liability or expense reasonably incurred
without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in
reliance on any Officer’s Certificate furnished pursuant to this Section 10.4.

 

Section 10.5. [Reserved.]

 

Section 10.6. [Reserved.]

 

Section 10.7. Corporate Existence.

 

Subject to
Article 8, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate
existence and that of each of its Restricted Subsidiaries and their respective rights (charter and statutory) and franchises;
provided, however, that the foregoing shall not obligate the Company or any of its Restricted Subsidiaries to preserve any such
right or franchise if the Company or any such Restricted Subsidiary shall determine that the preservation thereof is no longer
desirable in the conduct of its business or the business of such Restricted Subsidiary and that the loss thereof is not disadvantageous
in any material respect to any Holder.

Section 10.8. Waiver of Certain
Covenants.

 

The Company
may omit in any particular instance to comply with any term, provision or condition set forth in Section 10.7 with respect to
the Securities of any series if before the time for such compliance the Holders of at least a majority in principal amount of
the Outstanding Securities of such series, by Act of such Holders, either shall waive such compliance in such instance or generally
shall have waived compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision
or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company
and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

 

Section 10.9. Company Statement
as to Compliance; Notice of Certain Defaults.

 

(1) The Company
shall deliver to the Trustee, within 120 days after the end of each fiscal year, a written statement (which need not be contained

(a) a review
of the activities of the Company during such year and of its performance under this Indenture has been made under his or her supervision,
and

 

(b) to the
best of his or her knowledge, based on such review, (a) the Company has complied with all the conditions and covenants imposed
on it under this Indenture throughout such year, or, if there has been a default in the fulfillment of any such condition or covenant,
specifying each such default known to him or her and the nature and status thereof, and (b) no event has occurred and is continuing
which is, or after notice or lapse of time or both would become, an Event of Default, or, if such an event has occurred and is
continuing, specifying each such event known to him and the nature and status thereof.

 

(2) The Company
shall deliver to the Trustee, within five days after the occurrence thereof, written notice of any Event of Default or any event
which after notice or lapse of time or both would become an Event of Default pursuant to clause (4) of Section 5.1.

 

(3) The Trustee

Section 11.1. Applicability
of Article.

 

Redemption
of Securities of any series at the option of the Company as permitted or required by the terms of such Securities shall be made
in accordance with the terms of such Securities and (except as otherwise provided herein or pursuant hereto) this Article.

 

Section 11.2. Election to
Redeem; Notice to Trustee.

 

The election
of the Company to redeem any Securities shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at
the election of the Company of (a) less than all of the Securities of any series or (b) all of the Securities of any series, with
the same issue date, interest rate or formula, Stated Maturity and other terms, the Company shall, at least 60 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date and of the principal amount of Securities of such series to be redeemed.

 

    - 62 -

     

    

 

Section 11.3. Selection by
Trustee of Securities to be Redeemed.

 

Unless otherwise
specified as contemplated by Section 3.1, if less than all of the Securities of any series with the same issue date, interest
rate or formula, Stated Maturity and other terms are to be redeemed, the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee from the Outstanding Securities of such series not previously
called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for
redemption of portions of the principal amount of Registered Securities of such series; provided, however, that no such partial
redemption shall reduce the portion of the principal amount of a Registered Security of such series not redeemed to less than
the minimum denomination for a Security of such series established herein or pursuant hereto.

 

The Trustee
shall promptly notify the Company and the Security Registrar (if other than itself) in writing of the Securities selected for
redemption and, in the case of any Securities 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 shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal of such Securities which
has been or is to be redeemed.

 

Unless otherwise
specified in or pursuant to this Indenture or the Securities of any series, if any Security selected for partial redemption is
converted into other securities of the Company or exchanged for securities of another issuer in part before termination of the
conversion or exchange right with respect to the portion of the Security so selected, the converted portion of such Security shall
be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted or exchanged during
a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection.

 

Section 11.4. Notice of Redemption.

 

Notice of
redemption shall be given in the manner provided in Section 1.6, not less than 30 nor more than 60 days prior to the Redemption
Date, unless a shorter period is specified in the Securities to be redeemed, to the Holders of Securities to be redeemed. Failure
to give notice by mailing in the manner herein provided to the Holder of any Registered Securities designated for redemption as
a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption
of any other Securities or portion thereof.

 

Any notice
that is mailed to the Holder of any Registered Securities in the manner herein provided shall be conclusively presumed to have
been duly given, whether or not such Holder receives the notice.

 

All notices
of redemption shall state:

 

(1) the Redemption
Date,

 

(2) the Redemption
Price,

 

    - 63 -

     

    

 

(3) if less
than all Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption,
the principal amount) of the particular Security or Securities to be redeemed,

 

(4) in case
any Security is to be redeemed in part only, the notice which relates to such Security shall state that on and after the Redemption
Date, upon surrender of such Security, the Holder of such Security will receive, without charge, a new Security or Securities
of authorized denominations for the principal amount thereof remaining unredeemed,

 

(5) that,
on the Redemption Date, the Redemption Price shall become due and payable upon each such Security or portion thereof to be redeemed,
and, if applicable, that interest thereon shall cease to accrue on and after said date,

 

(6) the place
or places where such Securities, together (in the case of Bearer Securities) with all Coupons appertaining thereto, if any, maturing
after the Redemption Date, are to be surrendered for payment of the Redemption Price and any accrued interest and Additional Amounts
pertaining thereto,

 

(7) that the
redemption is for a sinking fund, if such is the case,

 

(8) that,
unless otherwise specified in such notice, Bearer Securities of any series, if any, surrendered for redemption must be accompanied
by all Coupons maturing subsequent to the date fixed for redemption or the amount of any such missing Coupon or Coupons will be
deducted from the Redemption Price, unless security or indemnity satisfactory to the Company, the Trustee and any Paying Agent
is furnished,

 

(9) if Bearer
Securities of any series are to be redeemed and no Registered Securities of such series are to be redeemed, and if such Bearer
Securities may be exchanged for Registered Securities not subject to redemption on the Redemption Date pursuant to Section 3.5
or otherwise, the last date, as determined by the Company, on which such exchanges may be made,

 

(10) in the
case of Securities of any series that are convertible into Common Stock of the Company or exchangeable for other securities, the
conversion or exchange price or rate, the date or dates on which the right to convert or exchange the principal of the Securities
of such series to be redeemed will commence or terminate and the place or places where such Securities may be surrendered for
conversion or exchange, and

 

(11) the CUSIP
number or the Euroclear or the Cedel reference numbers of such Securities, if any (or any other numbers used by a Depository to
identify such Securities).

 

A notice of
redemption published as contemplated by Section 1.6 need not identify particular Registered Securities to be redeemed.

 

Notice of
redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s
request, by the Trustee in the name and at the expense of the Company.

 

Section 11.5. Deposit of
Redemption Price.

 

On or prior
to any Redemption Date, the Company shall deposit, with respect to the Securities of any series called for redemption pursuant
to Section 11.4, with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and
hold in trust as provided in Section 10.3) an amount of money in the applicable Currency sufficient to pay the Redemption Price
of, and (except if the Redemption Date shall be an Interest Payment Date, unless otherwise specified pursuant to Section 3.1 or
in the Securities of such series) any accrued interest on and Additional Amounts with respect thereto, all such Securities or
portions thereof which are to be redeemed on that date.

 

    - 64 -

     

    

 

Section 11.6. Securities
Payable on Redemption Date.

 

Notice of
redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable
at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the
Redemption Price and accrued interest) such Securities shall cease to bear interest and the Coupons for such interest appertaining
to any Bearer Securities so to be redeemed, except to the extent provided below, shall be void. Upon surrender of any such Security
for redemption in accordance with said notice, together with all Coupons, if any, appertaining thereto maturing after the Redemption
Date, such Security shall be paid by the Company at the Redemption Price, together with any accrued interest and Additional Amounts
to the Redemption Date; provided, however, that, except as otherwise provided in or pursuant to this Indenture or the Bearer Securities
of such series, installments of interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall
be payable only upon presentation and surrender of Coupons for such interest (at an Office or Agency located outside the United
States except as otherwise provided in Section 10.2), and provided, further, that, except as otherwise specified in or pursuant
to this Indenture or the Registered Securities of such series, installments of interest on Registered Securities whose Stated
Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the Regular Record Dates therefor according to their terms and the
provisions of Section 3.7.

 

If any Bearer
Security surrendered for redemption shall not be accompanied by all appurtenant Coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal to the face amount of all such missing Coupons,
or the surrender of such missing Coupon or Coupons may be waived by the Company and the Trustee if there be furnished to them
such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of
such Security shall surrender to the Trustee or any Paying Agent any such missing Coupon in respect of which a deduction shall
have been made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided, however,
that any interest or Additional Amounts represented by Coupons shall be payable only upon presentation and surrender of those
Coupons at an Office or Agency for such Security located outside of the United States except as otherwise provided in Section
10.2.

 

If any Security
called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium, until paid, shall
bear interest from the Redemption Date at the rate prescribed therefor in the Security.

 

Section 11.7. Securities
Redeemed in Part.

 

Any Registered
Security which is to be redeemed only in part shall be surrendered at any Office or Agency for such Security (with, if the Company
or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the
Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing) and the Company shall execute and the
Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Registered Security or Securities
of the same series, containing identical terms and provisions, of any authorized denomination as requested by such Holder in aggregate
principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. If a Security
in global form is so surrendered, the Company shall execute, and the Trustee shall authenticate and deliver to the U.S. Depository
or other Depository for such Security in global form as shall be specified in the Company Order with respect thereto to the Trustee,
without service charge, a new Security in global form in a denomination equal to and in exchange for the unredeemed portion of
the principal of the Security in global form so surrendered.

SINKING
FUNDS

 

Section 12.1. Applicability
of Article.

 

The provisions
of this Article shall be applicable to any sinking fund for the retirement of Securities of a series, except as otherwise permitted
or required in or pursuant to this Indenture or any Security of such series issued pursuant to this Indenture.

 

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 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 12.2. Each sinking
fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such
series and this Indenture.

 

Section 12.2. 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 (1) deliver Outstanding Securities of such series (other than any of such Securities previously
called for redemption or any of such Securities in respect of which cash shall have been released to the Company), together in
the case of any Bearer Securities of such series with all unmatured Coupons appertaining thereto, and (2) apply as a credit Securities
of such series which have been redeemed either at the election of the Company pursuant to the terms of such series of Securities
or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, provided that
such series of Securities have not been previously so credited. Such Securities shall be received and credited for such purpose
by the Trustee at the Redemption 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 of any
series in lieu of cash payments pursuant to this Section 12.2, the principal amount of Securities of such series to be redeemed
in order to satisfy the remaining sinking fund payment shall be less than $100,000, the Trustee need not call Securities of such
series for redemption, except upon Company Request, 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 Paying Agent shall at the request of
the Company from time to time 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 requested to be released to the Company.

 

Section 12.3. Redemption
of Securities for Sinking Fund.

 

Not less than
75 days prior to each sinking fund payment date for any series of Securities, the Company shall deliver to the Trustee an Officer’s
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 12.2, and the optional amount, if
any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the Trustee any Securities
to be so credited and not theretofore delivered. If such Officer’s Certificate shall specify an optional amount to be added
in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to pay the amount therein
specified. Not less than 60 days 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 11.3 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 11.4. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner stated in Sections 11.6 and 11.7.

REPAYMENT
AT THE OPTION OF HOLDERS

 

Section 13.1. Applicability
of Article.

 

Securities
of any series which are repayable at the option of the Holders thereof before their Stated Maturity shall be repaid in accordance
with the terms of the Securities of such series. The repayment of any principal amount of Securities pursuant to such option of
the Holder to require repayment of Securities before their Stated Maturity, for purposes of Section 3.9, shall not operate as
a payment, redemption or satisfaction of the Indebtedness represented by such Securities unless and until the Company, at its
option, shall deliver or surrender the same to the Trustee with a directive that such Securities be cancelled. Notwithstanding
anything to the contrary contained in this Section 13.1, in connection with any repayment of Securities, the Company may arrange

present or represented at the meeting.

 

Section 15.5. Determination

of proxies and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates
and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall deem appropriate.

of the person executing the proxy witnessed or guaranteed by any trust company, bank or banker authorized by Section 1.4 to certify

face, may be presumed valid and genuine without the proof specified in Section 1.4 or other proof.

 

(2) The Trustee
shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 15.2(2), in which case the Company or the Holders of Securities
of the series calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman
and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in principal amount
of the Outstanding Securities of such series represented at the meeting.

 

(3) At any
meeting, each Holder of a Security of such series or proxy shall be entitled to one vote for each $1,000 principal amount of Securities

any resolution submitted to any meeting of Holders of Securities of any series shall be by written ballots on which shall be subscribed
the signatures of the Holders of Securities of such series or of their representatives by proxy and the principal amounts and

shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall
make and file with the secretary of the meeting their verified written reports in triplicate of all votes cast at the meeting.
A record, at least in triplicate, of the proceedings of each meeting of Holders of Securities of any series shall be prepared
by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on
any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the

SUBORDINATION
OF SECURITIES

 

Section 16.1. Securities
Subordinate to Senior Indebtedness.

 

The Company
covenants and agrees, and each Holder of a Security, by his acceptance thereof, likewise covenants and agrees, that, to the extent
and in the manner hereinafter set forth in this Article, the Indebtedness represented by the Securities and the payment of the
principal of (and premium, if any) and interest on each and all of the Securities are hereby expressly made subordinate and subject
in right of payment to the prior payment in full of all Senior Indebtedness.

 

Notwithstanding
the foregoing, if a deposit referred to in Section 4.2(4)(a) is made pursuant to Section 4.2(2) or Section 4.2(3) with respect
to any Securities (and provided all other conditions set out in Section 4.2(4) shall have been satisfied with respect to such
Securities), then, following such deposit or following the 123rd day after such deposit with respect to defeasance only, no money
or Government Obligations so deposited, and no proceeds thereon, will be subject to any rights of holders of Senior Indebtedness,
including any such rights arising under this Article 16.

 

Section
16.2. Payment Over of Proceeds Upon Dissolution, Etc.

 

In the event
of (a) any insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case
or proceeding in connection therewith, relative to the Company or to its creditors, as such, or to its assets, or (b) any liquidation,
dissolution or other winding up of the Company, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy,
or (c) any assignment for the benefit of creditors or any other marshalling of assets and liabilities of the Company, then and
in any such event 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, or provision shall be made for such payment in cash or cash equivalents or otherwise
in a manner satisfactory to the holders of Senior Indebtedness, before the Holders of the Securities are entitled to receive any
payment or distribution of any kind or character, whether in cash, property or securities (including any payment or distribution
which may be payable or deliverable by reason of the payment of any other Indebtedness of the Company subordinated to the payment
of the Securities), on account of principal of (or premium, if any) or interest on the Securities or on account of any purchase
or other acquisition of Securities by the Company or any Subsidiary of the Company (all such payments, distributions, purchases
and acquisitions herein referred to, individually and collectively, as a “Securities Payment”), and to that end the
holders of Senior Indebtedness shall be entitled to receive, for application to the payment thereof, any Securities Payment.

 

    - 70 -

     

    

 

In the event
that, notwithstanding the foregoing provisions of this Section, the Trustee or the Holder of any Security shall have received
any Securities Payment, before all Senior Indebtedness is paid in full or payment thereof provided for in cash or cash equivalents
or otherwise in a manner satisfactory to holders of Senior Indebtedness, and if such fact shall, at or prior to the time of such
Securities Payment, have been made known to the Trustee or, as the case may be, such Holder, then and in such event such Securities
Payment shall be paid over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee,
agent or other Person making payment or distribution of assets of the Company 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 of Senior Indebtedness. Any taxes that have been withheld or deducted from any Securities
Payment, or any taxes that ought to have been withheld or deducted from any such Securities Payment that have been remitted to
the relevant taxing authority, shall not be considered to be an amount that the Trustee or the Holder of any Security receives
for purposes of this Section.

 

For purposes
of this Article only, the words “cash, property or securities” shall not be deemed to include shares of stock of the
Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization
or readjustment which are subordinated in right of payment to all Senior Indebtedness which may at the time be outstanding to
substantially the same extent as, or to a greater extent than, the Securities are so subordinated as provided in this Article.
The consolidation of the Company with, or the merger of the Company into, another Person or the liquidation or dissolution of
the Company following the conveyance or transfer of its properties and assets substantially as an entirety to another Person upon
the terms and conditions set forth in Article 8 shall not be deemed a dissolution, winding up, liquidation, reorganization, assignment
for the benefit of creditors or marshalling of assets and liabilities of the Company for the purposes of this Section if the Person
formed by such 51 consolidation or into which the Company is merged or which acquires by conveyance or transfer such properties
and assets substantially as an entirety, as the case may be, shall, as a part of such consolidation, merger, conveyance or transfer,
comply with the conditions set forth in Article 8.

 

Section 16.3. No Payment
when Senior Indebtedness in Default.

 

Anything in
this Indenture to the contrary notwithstanding, no Securities Payment shall be made by or on behalf of the Company (i) unless
full payment of amounts then due for principal and interest and of all other obligations then due on all Senior Indebtedness has
been made or duly provided for pursuant to the terms of the instrument governing such Senior Indebtedness, (ii) if, at the time
of such payment, redemption, purchase or other acquisition, or immediately after giving effect thereto, there shall exist under
any Senior Indebtedness, or any agreement pursuant to which any Senior Indebtedness is issued, any default, which default shall
not have been cured or waived and which default shall have resulted in the full amount of such Senior Indebtedness being declared
due and payable or (iii) if, at the time of such payment, redemption, purchase or other acquisition, the Trustee shall have received
written notice from the holder or holders of any Senior Indebtedness or their representative or representatives (a “Payment
Blockage Notice”) that there exists under such Senior Indebtedness, or any agreement pursuant to which such Senior Indebtedness
is issued, any default, which default shall not have been cured or waived, permitting the holders thereof to declare the full
amount of such Senior Indebtedness due and payable, but only for the period (the “Payment Blockage Period”) commencing
on the date of receipt of the Payment Blockage Notice and ending (unless earlier terminated by notice given to the Trustee by
the Holders of such Senior Indebtedness) on the earlier of (A) the date on which such event of default shall have been cured or
waived or shall have ceased to exist or the Senior Indebtedness to which such default relates shall have been discharged or (B)
180 days from the receipt of the Payment Blockage Notice; provided, however, that nothing in this Section shall prevent the satisfaction
of any sinking fund payment in accordance with Article 12 hereof by delivery and crediting pursuant to Section 12.2 Securities
which have been acquired (upon redemption or otherwise) prior to the acceleration of any such default listed in (i) or (ii) directly
above or prior to receipt of any Payment Blockage Notice. Upon termination of a Payment Blockage Period, payments on account of
principal of, premium, if any, or interest on the Securities, and redemptions, purchases or other acquisitions may be made by
or on behalf of the Company. Notwithstanding anything herein to the contrary, (A) only one Payment Blockage Notice may be given
during any period of 360 consecutive days with respect to the same event of default and any other events of default on the same
issue of Senior Indebtedness existing and known to the person giving such notice at the time of such notice and (B) no new Payment
Blockage Period may be commenced by the holder or holders of the same issue of Senior Indebtedness or their representative or
representatives during any period of 360 consecutive days unless all events of default which were the object of the immediately
preceding Payment Blockage Notice, and any other event of default on the same issue of Senior Indebtedness existing and known
to the person giving such notice at the time of such notice, have been cured or waived for a period of at least 90 consecutive
days.

 

    - 71 -

     

    

 

In the event
that, notwithstanding the provisions of this Section 16.3, payments are made by or on behalf of the Company in contravention of
the provisions of this Section 16.3, such payments shall be held by the Trustee, any Paying Agent or the Holders, as applicable,
in trust for the benefit of, and shall be paid over to and delivered to, the holders of Senior Indebtedness or their representative
or the trustee under the indenture or other agreement (if any), pursuant to which any instruments evidencing any Senior Indebtedness
may have been issued, as their respective interests may appear, for application to the payment of all Senior Indebtedness remaining
unpaid to the extent necessary to pay all Senior Indebtedness in full in accordance with the terms of such Senior Indebtedness,
after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness.

 

The provisions
of this Section shall not apply to any payment with respect to which Section 16.2 would be applicable.

 

Section 16.4. Reliance by
Senior Indebtedness on Subordination Provisions.

 

Each Holder
of any Security by his acceptance thereof acknowledges and agrees that the foregoing subordination provisions are, and are intended
to be, an inducement and a consideration for each holder of any Senior Indebtedness, whether such Senior Indebtedness was created
or acquired before or after the issuance of the Securities, to acquire and continue to hold, or to continue to hold, such Senior
Indebtedness, and such holder of Senior Indebtedness shall be deemed conclusively to have relied on such subordination provisions
in acquiring and continuing to hold or in continuing to hold such Senior Indebtedness.

 

Section 16.5. 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 Company, at any time except during
the pendency of any case, proceeding, dissolution, liquidation or other winding up, assignment for the benefit of creditors or
other marshalling of assets and liabilities of the Company referred to in Section 16.2 or under the conditions described in Section
16.3, from making Securities Payments, or (b) the application by the Trustee of any money deposited with it hereunder to Securities
Payments or the retention of such Securities Payments by the Holders, if, at the time of such application by the Trustee, it did
not have knowledge that such Securities Payments would have been prohibited by the provisions of this Article.

 

    - 72 -

     

    

 

Section 16.6. Subrogation
to Rights of Holders of Senior Indebtedness.

 

Subject to
the payment in full of all Senior Indebtedness or the provision for such payment in cash or cash equivalents or otherwise in a
manner satisfactory to the holders of 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 (equally
and ratably with the holders of all indebtedness of the Company which by its express terms is subordinated to indebtedness of
the Company to substantially the same extent as the Securities are subordinated and is entitled to like rights of subrogation)
to the rights of the holders of such Senior Indebtedness to receive payments and distributions of cash, property and securities
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 of any cash,
property or securities 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 among the Company, its creditors other than holders of Senior Indebtedness and the Holders
of the Securities, be deemed to be a payment or distribution by the Company to or on account of the Senior Indebtedness.

 

Section 16.7. 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 (a) impair, as among the Company, its creditors other than holders of Senior
Indebtedness and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional (and which,
subject to the rights under this Article of the holders of Senior Indebtedness, is intended to rank equally with all other general
obligations of the Company), to pay to the Holders of the Securities the principal of (and premium, if any) and interest on the
Securities as and when the same shall become due and payable in accordance with their terms; or (b) affect the relative rights
against the Company of the Holders of the Securities and creditors of the Company other than the holders of Senior Indebtedness;
or (c) 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 and securities otherwise payable or deliverable to the Trustee or such Holder.

 

Section 16.8. Trustee to
Effectuate Subordination.

 

Each holder
of a Security by his acceptance thereof 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 16.9. 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 Company or by any act or failure to act, in good faith,
by any such holder, or by any non-compliance by the Company with the terms, provisions and covenants of this Indenture, regardless
of any knowledge thereof any such holder may have or be otherwise charged with.

 

    - 73 -

     

    

 

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 Trustee or 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
hereunder of the Holders of the Securities to the holders of Senior Indebtedness, do any one or more of the following: (i) change
the manner, place or terms of payment or extend the time 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 Company and any other Person.

 

Section 16.10. Notice to
Trustee.

 

The Company
shall give prompt written notice to the Trustee of any fact known to the Company which would prohibit the making of any payment
to or by the Trustee in respect of the Securities. 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, unless and until the Trustee shall have received written notice thereof
from the Company or a holder 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 6.1, shall be entitled in all respects to assume that no such facts
exist.

 

Subject to
the provisions of Section 6.1, the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing
himself to be a holder of Senior Indebtedness (or a trustee therefor) to establish that such notice has been given by a holder
of Senior Indebtedness (or a trustee therefor). 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 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 16.11. Reliance on
Judicial Order or Certificate of Liquidating Agent.

 

Upon any payment
or distribution of assets of the Company referred to in this Article, the Trustee, subject to the provisions of Section 6.1, 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, receiver, liquidating trustee, custodian, 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 payment or distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article.

 

    - 74 -

     

    

 

Section 16.12. 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 and 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 Company 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.

 

Section 16.13. Rights of
Trustee as Holder of Senior Indebtedness; Preservation of Trustee’s Rights.

 

The Trustee
in its individual capacity shall be entitled to all the rights set forth in this Article with respect to any Senior Indebtedness
which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture
shall deprive the Trustee of any of its rights as such holder.

 

Nothing in
this Article shall apply to claims of, or payments to, the Trustee under or pursuant to Section 6.7.

 

Section 16.14. Article Applicable
to Paying Agents.

 

In case at
any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term
“Trustee” as used in this Article shall in such case (unless the context otherwise requires) be construed as extending
to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named
in this Article in addition to or in place of the Trustee; provided, however, that Section 16.13 shall not apply to the Company
or any Affiliate of the Company if it or such Affiliate acts as Paying Agent.

 

Section 16.15. Defeasance
of this Article 16.

 

The subordination
of the Securities provided by this Article 16 is expressly made subject to the provisions for defeasance in Section 4.2(2) hereof
or covenant defeasance in Section 4.2(3) hereof and, anything herein to the contrary notwithstanding, upon the effectiveness of
any such defeasance or covenant defeasance, the Securities then outstanding shall thereupon cease to be subordinated pursuant
to this Article 16.]

 Exhibit 10.1 

AMENDMENT TO THE EMPLOYMENT AGREEMENT 

This FIRST AMENDMENT TO THE EMPLOYMENT AGREEMENT (this “Amendment”), dated as of June 5, 2018 (the
“Effective Date”), is by and between Allied Power Management, LLC (the “Company”) and Dorsey Ron McCall (the “Executive”). 

RECITALS 

WHEREAS, the Company and the Employee are parties to that certain Amended and Restated Employment Agreement, dated as of July 12,
2017 (the “Employment Agreement”), and any terms not defined herein shall have the same meaning as in the Employment Agreement; and 

WHEREAS, the Company and the Executive desire to amend the Employment Agreement, effective as of the Effective Date, according to the
terms and conditions set forth in this Amendment, to account for certain changes to the terms of Employee’s employment. 
 NOW,
THEREFORE, in consideration of the mutual promises, agreements, and consideration set forth below, the parties agree to the following terms: 

WITNESSETH 
 1. The
first sentence of Section 2(a) is hereby and amended and restated as follows: 
 “Executive shall serve as the Senior Vice
President of Charah Solutions, Inc. and shall have the normal duties, responsibilities, functions and authority customarily associated with such office, subject to the power of the governing body of Charah Solutions, Inc. to reasonably modify such
duties, responsibilities, functions and authority so long as such duties, responsibilities, functions and authority, as modified, continue to be customary for a senior vice president and are in keeping with such position.” 

2. New Section 3(c) is hereby added and reads as follows: 

“(c) Executive shall be entitled to receive a bonus (the “Incentive Bonus”) equal to 7.5% of EBITDA generated by new
international operations focused on nuclear operations (“International Nuclear Operations”) (EBITDA as defined by GAAP and determined in the discretion of the Employer’s primary outside auditor), less any costs associated or
incurred in connection with such International Nuclear Operations, provided that in any given fiscal year EBITDA is negative, such negative amount will adjust the EBITDA targets for the following fiscal year(s), The Incentive Bonus shall be
payable annually and as soon as practicable following the Employer’s completion of its audited financials for the fiscal year to which the Incentive Bonus applies. An additional 7.5% of EBITDA generated by the International Nuclear Operations,
as calculated in accordance with the above, shall be allocated to certain employees of the Employer at the discretion of the Executive in consultation with the Employer. Notwithstanding anything to the contrary in this Agreement, upon
Executive’s termination by the Employer without Cause (as defined below) or due to Executive’s Approved Retirement (as defined below), death or Disability (as defined below), subject to the release requirements set forth in
Section 4(c), Executive shall be eligible to receive (i) the Incentive Bonus Executive would have earned for the fiscal year of such termination without Cause or Approved Retirement, without regard for any pro-ration and (ii) a pro-rata portion of the Incentive Bonus Executive would have earned for the fiscal year following the fiscal year of
such termination without Cause or Approved Retirement, with such pro-rata 

 
portion determined based on the quotient determined by dividing the number of days between the beginning of the fiscal year in which such termination occurs and the date of Employee’s
termination of employment, divided by 365, which will be payable at such time as the Incentive Bonus would be paid according to this Section 3(c), which for the avoidance of doubt, shall be payable in the year following
the year to which such Incentive Bonus applies. For purposes of this Section 3(c), “Approved Retirement” means the Executive’s termination of employment as a result of the Executive’s voluntary resignation of
employment following ninety (90) days prior written notice to the Employer at such time that the Executive is at least 65 years of age.” 

3. Existing Sections 3(c), (d), (e), (f) and (g) are hereby renumbered to Sections 3(d), (e), (f), (g), and (h), respectively, and all
references to these sections in the Agreement shall reference the renumbered section. 
 4. Construction. Except as specifically
provided in this Amendment, the Employment Agreement will remain in full force and effect and is hereby ratified and confirmed in all respects. 

5. Governing Law. This Amendment shall be construed under and enforced in accordance with the laws of the State of Louisiana, in
accordance with Section 16 of the Employment Agreement. 
 6. Entire Agreement. The Employment Agreement, as amended by this
Amendment effective as of the Effective Date, embodies the entire agreement and understanding between the parties hereto and supersedes all prior agreements and understandings relating to the subject matter hereof. No agreements or representations,
oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party which are not expressly set forth in the Employment Agreement and this Amendment. 

7. Counterparts. This Amendment may be executed in several counterparts, each of which shall be deemed to be an original but all of
which together will constitute one and the same instrument.
