(v)          Securities
converted into Common Shares or Preferred Shares pursuant to or in accordance with this Indenture if the terms of such Securities
provide for convertibility pursuant to Section 3.01;

 

provided, however,
that in determining whether the Holders of the requisite principal amount of the Outstanding Securities have given any request,
demand, authorization, direction, notice, consent or waiver hereunder or are present at a meeting of Holders for quorum purposes,
and for the purpose of making the calculations required by TIA Section 313, (i) the principal amount of an Original Issue Discount
Security that may be counted in making such determination or calculation and that shall be deemed to be Outstanding for such purpose
shall be equal to the amount of principal thereof that would be (or shall have been declared to be) due and payable, at the time

amount of any Security denominated in a Foreign Currency or Currencies that may be counted in making such determination or calculation
and that shall be deemed Outstanding for such purpose shall be equal to the Dollar equivalent, determined pursuant to Section 3.01
as of the date such Security is originally issued by the Company, of the principal amount (or, in the case of an Original Issue
Discount Security, the Dollar equivalent as of such date of original issuance of the amount determined as provided in clause (i)
above) of such Security, (iii) the principal amount of any Indexed Security that may be counted in making such determination or
calculation and that shall be deemed outstanding for such purpose shall be equal to the principal face amount of such Indexed Security
at original issuance, unless otherwise provided with respect to such Security pursuant to Section 3.01, and (iv) Securities owned
by the Company or any other obligor upon the Securities or any Affiliate of the Company or of such other obligor shall be disregarded
and deemed not to be Outstanding, except that, in determining whether the Trustee shall be protected in making such calculation
or in relying upon any such request, demand, authorization, direction, notice, consent or waiver, only Securities which the Trustee
knows to be so owned shall be so disregarded. Securities so owned which have been pledged in good faith may be regarded as Outstanding
if the pledgee establishes to the satisfaction of the Trustee the pledgee's right so to act with respect to such Securities and
that the pledgee is not the Company or any other obligor upon the Securities or any Affiliate of the Company or of such other obligor.

to such maturity, yields for the two published maturities most closely corresponding to such maturity shall be calculated pursuant
to the immediately preceding sentence and the Reinvestment Rate shall be interpolated or extrapolated from such yields on a straight-line
basis, rounding in each of such relevant periods to the nearest month. For the purposes of calculating the Reinvestment Rate, the
most recent Statistical Release published prior to the date of determination of the Make-Whole Amount shall be used. If the format

Section
1.03          Form of Documents Delivered to Trustee.

Section
1.04          Acts of Holders.

 

(a)          Any
request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken
by Holders of the Outstanding Securities of all series or one or more series, as the case may be, may be embodied in and evidenced
by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing.
If Securities of a series are issuable as Bearer Securities, any request, demand, authorization, direction, notice, consent, waiver
or other action provided by 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 Fifteen, 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 conclusive in favor
of the Trustee and the Company and any agent of the Trustee or 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 15.06.

 

Without limiting the
generality of this Section 1.04, 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 action 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.

 

    	11

    	 

    
 

The Trustee shall fix
a record date for the purpose of determining the Persons who are beneficial owners of interests 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 action provided in or pursuant
to this Indenture to be made, given or taken by Holders. If such a record date is fixed, the Persons who are beneficial owners
of interests 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 Persons remain
beneficial owners after such record date.

 

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

 

(c)          The
ownership of Registered Securities shall be proved by the Security Register.

 

(d)          The
ownership of Bearer Securities 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, wherever situated, if such certificate shall be deemed by 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 reasonably satisfactory. The Trustee and the
Company may assume that such ownership of any Bearer Security continues until (1) another certificate or affidavit bearing a later
date issued in respect of the same Bearer Security is produced, or (2) such Bearer Security is produced to the Trustee by some
other Person, or (3) such Bearer Security is surrendered in exchange for a Registered Security, or (4) such Bearer Security is
no longer Outstanding. The ownership of Bearer Securities may also be proved in any other reasonable manner which the Trustee deems
sufficient.

 

(e)          If
the Company shall solicit from the Holders of Registered Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may, at its option, in or pursuant to a Board Resolution, fix in advance a record date for the
determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act,
but the Company shall have no obligation to do so. Notwithstanding TIA Section 316(c), such record date shall be the record date
specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation
of Holders generally in connection therewith and not later than the date such solicitation is completed. 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 record at the close of business on such record date shall be deemed to be Holders for the
purposes 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 on such record
date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven
months after the record date.

 

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

Section
1.05          Notices, etc., to Trustee, Company and agents.

 

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

 

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

 

(2)          the
Company by the Trustee or by 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 it at the address of its principal office specified
in the first paragraph of this Indenture, Attention: Chief Legal Officer, or at any other address previously furnished in writing
to the Trustee by the Company, or if delivered by electronic mail, or

 

(3)          any
agent of the Company, including any conversion agent, Security Registrar or Paying Agent, by any Holder or by the Company shall
be sufficient for every purpose hereunder if made, given, furnished or filed in writing, including by electronic mail, to such
agent.

 

Section
1.06          Notice to Holders; Waiver.

 

Where this Indenture
provides for notice of any event to Holders of Registered Securities by the Company or the Trustee, such notice shall be sufficiently
given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each such Holder 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. 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 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 mailed to a Holder in the manner herein prescribed shall be conclusively
deemed to have been received by such Holder, whether or not such Holder actually receives such notice.

 

If by reason of the
suspension of or irregularities in regular mail service or by reason of any other cause it shall be impracticable to give such
notice by mail, then such notification to Holders of Registered Securities as shall be made with the approval of the Trustee shall
constitute a sufficient notification to such Holders for every purpose hereunder.

 

Except as otherwise
expressly provided herein or otherwise specified with respect to any Securities pursuant to Section 3.01, where this Indenture
provides for notice to Holders of Bearer Securities of any event, such notice shall be sufficiently given if published in an Authorized
Newspaper in The City of New York and in such other city or cities as may be specified in such Securities on a Business Day, such
publication to be not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice.
Any such notice shall be deemed to have been given on the date of such publication or, if published more than once, on the date
of the first such publication.

 

    	13

    	 

    
 

If 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 Bearer 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 the 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 to Holders of Registered Securities given as provided herein.

 

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

 

Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

 

Notwithstanding any
other provision of this Indenture or any Security, where this Indenture or any Security provides for notice of any event (including
any notice of redemption or repurchase) to a Holder of a global Security (whether by mail or otherwise), as long as DTC is the
depository therefor, such notice shall be sufficiently given if given to DTC (or its designee) pursuant to the standing instructions
from DTC or its designee, including by electronic mail in accordance with DTC operational arrangements or other applicable DTC
requirements.

In any case where any
Interest Payment Date, Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity or Maturity of any Security
shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or any Security
or coupon other than a provision in the Securities of any series which specifically states that such provision shall apply in lieu
hereof), payment of interest or any Additional Amounts or principal (and premium, if any) need not be made at such Place of Payment

made on the Interest Payment Date, Redemption Date, Repayment Date or sinking fund payment date, or at the Stated Maturity or Maturity,
provided that no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption
Date, Repayment Date, sinking fund payment date, Stated Maturity or Maturity, as the case may be.

 

Section
1.13          Judgment Currency.

 

To the fullest extent
permitted by applicable law, (i) if for the purpose of obtaining judgment in any court it is necessary to convert the amount due
in respect of the principal of, or premium, if any, or interest, or Additional Amounts with respect to, the Securities of any series
from the currency in which it is due (the "Required Currency") into a currency in which the judgment will be rendered
(the "Judgment Currency"), the rate of exchange used shall be the rate at which in accordance with normal banking procedures
the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on the New York Banking Day
preceding the day on which such judgment is given, and (ii) the Company's obligations under this Indenture to make payments in
the Required Currency shall, despite any judgment in the Judgment Currency, be discharged by a payment on account thereof in the
Judgment Currency only to the extent that, on the New York Banking Day following receipt of such payment in the Judgment Currency,
the Trustee may, in accordance with normal banking procedures, purchase in The City of New York the Required Currency with the
amount of the Judgment Currency so paid; and if the amount of the Required Currency that may be so purchased is less than the amount
originally due in the Required Currency, the Company shall have a separate and independent obligation, despite any such payment
or judgment, to indemnify the payee against such deficiency. For purposes of the foregoing, "New York Banking Day" means
any day other than a Saturday, Sunday, legal holiday or other day on which banking institutions in The City of New York are authorized
or required by law, regulation or executive order to close.

officer or director, as such, of the Company or any Guarantor or of any successor thereof, either directly or through the Company
or any Guarantor or any successor thereof, under any rule of law, statute or constitutional provision or by the enforcement of
any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by
the acceptance of the Securities by the Holders thereof and as part of the consideration for the issue of the Securities.

The Company and the
Guarantors acknowledge that in accordance with Section 326 of the U.S.A. PATRIOT Act, the Trustee, like all financial institutions

Section
2.03          Securities Issuable in Global Form.

 

If Securities of or
within a series are issuable in global form, as specified as contemplated by Section 3.01, then, notwithstanding clause (8) of
Section 3.01 and the provisions of Section 3.02, any such Security shall represent such of the Outstanding Securities of such series
as shall be specified therein and may provide that it shall represent the aggregate amount of Outstanding Securities of such series
from time to time endorsed thereon and that the aggregate amount of Outstanding Securities of such series represented thereby may
from time to time be increased or decreased to reflect exchanges. Any endorsement of a Security in global form to reflect the amount,
or any increase or decrease in the amount, of Outstanding Securities represented thereby shall be made by the Trustee (or pursuant
to its direction) in such manner and upon instructions given by such Person or Persons as shall be specified therein or in the
Company Order to be delivered to the Trustee pursuant to Section 3.03 or 3.04. Subject to the provisions of Section 3.03 and, if
applicable, Section 3.04, the Trustee shall deliver and redeliver 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 3.03 or 3.04 has been, or simultaneously is, delivered, any instructions by the Company with respect to endorsement or
delivery or redelivery of a Security in global form shall be in writing but need not comply with Section 1.02 and need not be accompanied
by an Opinion of Counsel.

 

    	16

    	 

    
 

The provisions of the
last sentence of Section 3.03 shall apply to any Security represented by a Security in global form if such Security was never issued

(which need not comply with Section 1.02 and need not be accompanied by an Opinion of Counsel) with regard to the reduction in
the principal amount of Securities represented thereby, together with the written statement contemplated by the last sentence of
Section 3.03.

 

Notwithstanding the
provisions of Section 3.07, unless otherwise specified as contemplated by Section 3.01, payment of principal of and any premium
and interest on any Security in permanent global form shall be made to the Person or Persons specified therein.

 

Notwithstanding the
provisions of Section 3.08 and except as provided in the preceding paragraph, the Company, the Trustee and any agent of the Company
and the Trustee shall treat as the Holder of such principal amount of Outstanding Securities represented by a permanent global
Security (i) in the case of a permanent global Security in registered form, the Holder of such permanent global Security in registered
form, or (ii) in the case of a permanent global Security in bearer form, Euroclear or Clearstream.

case of Registered Securities, as to denomination and except as may otherwise be provided in or pursuant to such Board Resolution
(subject to Section 3.03) and set forth in such Officers' Certificate or in any such indenture supplemental hereto. All Securities
of any one series need not be issued at the same time and, unless otherwise provided, a series may be reopened, without the consent
of the Holders, for issuances of additional Securities of such series.

 

If any of the terms
of the Securities of any series are established by action taken pursuant to one or more Board Resolutions, a copy of an appropriate
record of such action(s) shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee
at or prior to the delivery of the Officers' Certificate setting forth the terms of the Securities of such series.

 

The Company in issuing
the Securities may use CUSIP, ISIN or other similar numbers, if then generally in use, and thereafter with respect to such series,
the Trustee may use such numbers in any notice with respect to such series provided that any such notice may state that no representation
is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice and that reliance
may be placed only on the other identification numbers printed on the Securities, and any such notice or notice shall not be affected
by any defect in or omission of such numbers. The Company will promptly notify the Trustee in writing of any change in the CUSIP,
ISIN or other similar numbers.

 

    	20

    	 

    
 

Section
3.02          Denominations.

 

The Securities of each
series shall be issuable in such denominations as shall be specified as contemplated by Section 3.01. With respect to Securities
of any series denominated in Dollars, in the absence of any such provisions with respect to the Securities of any series, the Registered
Securities of such series, other than Registered Securities issued in global form (which may be of any denomination), shall be
issuable in denominations of $1,000 and any integral multiple thereof and the Bearer Securities of such series, other than Bearer
Securities issued in global form (which may be of any denomination), shall be issuable in denominations of $5,000.

 

Section
3.03          Execution, Authentication, Delivery and Dating.

 

The Securities and
any coupons appertaining thereto shall be executed on behalf of the Company by its Chairman of the Board, its Chief Executive Officer,
its President or one of its Vice Presidents, and attested by its Secretary or one of its Assistant Secretaries. The signature of
any of these officers on the Securities and coupons may be manual or facsimile signatures of the present or any future such authorized
officer and may be imprinted or otherwise reproduced on the Securities.

 

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

 

At any time and from
time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series, together with
any coupon appertaining thereto, executed by the Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver
such Securities; provided, however, that, in connection with its original issuance, no Bearer Security shall be mailed or otherwise
delivered to any location in the United States; and provided further that, unless otherwise specified with respect to any series
of Securities pursuant to Section 3.01, a Bearer Security may be delivered in connection with its original issuance only if the
Person entitled to receive such Bearer Security shall have furnished a certificate to Euroclear or Clearstream, as the case may
be, in the form set forth in Exhibit A-1 to this Indenture or such other certificate as may be specified with respect to any series
of Securities pursuant to Section 3.01, dated no earlier than 15 days prior to the earlier of the date on which such Bearer Security
is delivered and the date on which any temporary Security first becomes exchangeable for such Bearer Security in accordance with
the terms of such temporary Security and this Indenture. If any Security shall be represented by a permanent global Bearer Security,
then, for purposes of this Section and Section 3.04, the notation of a beneficial owner's interest therein upon original issuance
of such Security or upon exchange of a portion of a temporary global Security shall be deemed to be delivery in connection with
its original issuance of such beneficial owner's interest in such permanent global Security. Except as permitted by Section 3.06,
the Trustee shall not authenticate and deliver any Bearer Security unless all appurtenant coupons for interest then matured have
been detached and canceled.

 

    	21

    	 

    
 

If all the Securities
of any series are not to be issued at one time and if the Board Resolution or supplemental indenture establishing such series shall
so permit, such Company Order may set forth procedures acceptable to the Trustee for the issuance of such Securities and determining
the terms of particular Securities of such series, such as interest rate or formula, maturity date, redemption or repayment provisions,
currency of denomination and payment, date of issuance and date from which interest shall accrue. 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 TIA Section 315(a) through 315(d)) shall be fully protected
in relying upon,

 

(i)          an
Opinion of Counsel stating that

 

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

 

(b)          the
terms of such Securities and any coupons have been established in conformity with the provisions of this Indenture; and

 

(c)          such
Securities, together with any coupons appertaining thereto, when completed by appropriate insertions and executed and delivered
by the Company to the Trustee for authentication in accordance with this Indenture, authenticated and delivered by the Trustee
in accordance with this Indenture and issued by the Company in the manner and subject to any conditions specified in such Opinion
of Counsel, will constitute legal, valid and binding obligations of the Company, enforceable in accordance with their terms, subject
to applicable bankruptcy, insolvency, reorganization and other similar laws of general applicability relating to or affecting the
enforcement of creditors' rights generally and to general equitable principles, and will entitle the Holders thereof to the benefits
of this Indenture and any related Guarantee issued pursuant hereto; and

 

(ii)          an
Officers' Certificate stating that all conditions precedent provided for in this Indenture relating to the issuance of the Securities
have been complied with and that, to the best of the knowledge of the signers of such certificate, no Event of Default with respect
to any of the Securities shall have occurred and be continuing.

 

If such form or terms
have been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant
to this Indenture will affect the Trustee's own rights, duties, obligations or immunities under the Securities and this Indenture
or otherwise in a manner which is not reasonably acceptable to the Trustee.

 

Notwithstanding the
provisions of Section 3.01 and of the second preceding paragraph, if all the Securities of any series are not to be issued at one
time, it shall not be necessary to deliver an Officers' Certificate otherwise required pursuant to Section 3.01 or a Company Order,
or an Opinion of Counsel or an Officers' Certificate otherwise required pursuant to the second preceding paragraph at the time
of issuance of each Security of such series, but such order, opinion and certificates, with appropriate modifications to cover
such future issuances, shall be delivered at or before the time of issuance of the first Security of such series. After any such
first delivery, any separate request by the Company that the Trustee authenticate 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.

 

Each Registered Security
shall be dated the date of its authentication and each Bearer Security shall be dated as of the date specified as contemplated
by Section 3.01.

 

    	22

    	 

    
 

No Security or coupon
shall be entitled to any benefit under this Indenture or any related Guarantee or be valid or obligatory for any purpose unless
there appears on such Security or Security to which such coupon appertains a certificate of authentication substantially in the
form provided for herein duly executed by the Trustee by manual signature of an authorized signatory, and such certificate upon
any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered
hereunder and is entitled to the benefits of this Indenture and any related Guarantee. Notwithstanding the foregoing, if any Security
shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 3.09 together with a written statement (which need not comply with
Section 1.02 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by
the Company, the Trustee shall be fully justified in relying thereon and in cancelling such Security and for all purposes of this
Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to
the benefits of this Indenture and any related Guarantee.

 

Section
3.04          Temporary Securities.

 

(a)          Pending
the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate
and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered form, or,
if authorized, in bearer form with one or more coupons or without coupons, and with such appropriate insertions, omissions, substitutions
and other variations as the officers executing such Securities may determine, as conclusively evidenced by their execution of such
Securities. In the case of Securities of any series, such temporary Securities may be in global form.

 

Except in the case
of temporary Securities in global form (which shall be exchanged in accordance with Section 3.04(b) or as otherwise provided in
or pursuant to a Board Resolution), if temporary Securities of any series are issued, the Company will cause definitive Securities
of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities
of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Securities of any series (accompanied by any non-matured 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 the same series of authorized denominations; provided, however, that no definitive Bearer Security
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 Section 3.03. 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.

 

(b)          Unless
otherwise provided in or pursuant to a Board Resolution, this Section 3.04(b) shall govern the exchange of temporary Securities
issued in global form other than through the facilities of DTC. If any such temporary Security is issued in global form, then such
temporary global Security shall, unless otherwise provided therein, be delivered to the London office of a depositary or common
depositary (the "Common Depositary"), for the benefit of Euroclear and Clearstream, for credit to the respective accounts
of the beneficial owners of such Securities (or to such other accounts as they may direct).

 

    	23

    	 

    
 

Without unnecessary
delay but in any event not later than the date specified in, or determined pursuant to the terms of, any such temporary global
Security (the "Exchange Date"), the Company shall deliver to the Trustee definitive Securities, in aggregate principal
amount equal to the principal amount of such temporary global Security, executed by the Company. On or after the Exchange Date,
such temporary global Security shall be surrendered by the Common Depositary to the Trustee, as the Company's agent for such purpose,
to be exchanged, in whole or from time to time in part, for definitive Securities without charge, and the Trustee shall authenticate
and deliver (subject to the Trustee's receipt of sufficient delivery instructions from, or provided by or on behalf of, the Common
Depositary), in exchange for each portion of such temporary global Security, an equal aggregate principal amount of definitive
Securities of the same series of authorized denominations and of like tenor as the portion of such temporary global Security to
be exchanged. The definitive Securities to be delivered in exchange for any such temporary global Security shall be in bearer form,
registered form, permanent global bearer form or permanent global registered form, or any combination thereof, as specified as
contemplated by Section 3.01, and, if any combination thereof is so specified, as requested by the beneficial owner thereof (as
identified or provided to the Trustee by the Common Depositary, or by Euroclear or Clearstream, as applicable); provided, however,
that, unless otherwise specified in such temporary global Security, upon such presentation by the Common Depositary, such temporary
global Security shall be accompanied by a certificate dated the Exchange Date or a subsequent date and signed by Euroclear as to
the portion of such temporary global Security held for its account then to be exchanged and a certificate dated the Exchange Date
or a subsequent date and signed by Clearstream as to the portion of such temporary global Security held for its account then to
be exchanged, each in the form set forth in Exhibit A-2 to this Indenture or in such other form as may be established pursuant
to Section 3.01; and provided further that definitive Bearer Securities shall be delivered in exchange for a portion of a temporary
global Security only in compliance with the requirements of Section 3.03.

 

Unless otherwise specified
in such temporary global Security, the interest of a beneficial owner of Securities of a series in a temporary global Security
shall be exchanged for definitive Securities of the same series and of like tenor following the Exchange Date when the account
holder instructs Euroclear or Clearstream, as the case may be, to request such exchange on his behalf and delivers to Euroclear
or Clearstream, as the case may be, a certificate in the form set forth in Exhibit A-1 to this Indenture (or in such other form
as may be established pursuant to Section 3.01), dated no earlier than 15 days prior to the Exchange Date, copies of which certificate
shall be available from the offices of Euroclear and Clearstream, the Trustee, any Authenticating Agent appointed for such series
of Securities and each Paying Agent. Unless otherwise specified in such temporary global Security, any such exchange shall be made
free of charge to the beneficial owners of such temporary global Security, except that a Person receiving definitive Securities
must bear the cost of insurance, postage, transportation and the like unless such Person takes delivery of such definitive Securities
in person at the offices of Euroclear or Clearstream. Definitive Securities in bearer form to be delivered in exchange for any
portion of a temporary global Security shall be delivered only outside the United States.

 

Until exchanged in
full as hereinabove provided, the temporary Securities of any series shall in all respects be entitled to the same benefits under
this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder, except that,
unless otherwise specified as contemplated by Section 3.01, interest payable on a temporary global Security on an Interest Payment
Date for Securities of such series occurring prior to the applicable Exchange Date shall be payable to Euroclear and Clearstream
on such Interest Payment Date upon delivery by Euroclear and Clearstream to the Trustee of a certificate or certificates in the
form set forth in Exhibit A-2 to this Indenture (or in such other forms as may be established pursuant to Section 3.01), for credit
without further interest on or after such Interest Payment Date to the respective accounts of Persons who are the beneficial owners
of such temporary global Security on such Interest Payment Date and who have each delivered to Euroclear or Clearstream, as the
case may be, a certificate dated no earlier than 15 days prior to the Interest Payment Date occurring prior to such Exchange Date
in the form set forth as Exhibit A-1 to this Indenture (or in such other forms as may be established pursuant to Section 3.01).

 

    	24

    	 

    
 

Notwithstanding anything
to the contrary herein contained, the certifications made pursuant to this paragraph shall satisfy the certification requirements
of the preceding two paragraphs of this Section 3.04(b) and of the third paragraph of Section 3.03 of this Indenture (in each case,
without delivery of a certificate in the form of Exhibit A-1) and the interests of the Persons who are the beneficial owners of
the temporary global Security with respect to which such certification was made will be exchanged for definitive Securities of
the same series and of like tenor on the Exchange Date or the date of certification if such date occurs after the Exchange Date,
without further act or deed by such beneficial owners. Except as otherwise provided in this paragraph, no payments of principal
or interest owing with respect to a beneficial interest in a temporary global Security will be made unless and until such interest
in such temporary global Security shall have been exchanged for an interest in a definitive Security. Any interest so received
by Euroclear and Clearstream and not paid as herein provided shall be returned to the Trustee prior to the expiration of two years
after such Interest Payment Date in order to be repaid to the Company (subject, however, to any abandoned property laws that may
be applicable).

 

Section
3.05          Registration, Registration of Transfer and Exchange.

 

The Company shall cause
to be kept at the Corporate Trust Office of the Trustee or in any office or agency of the Company in a Place of Payment a register
for each series of Securities (the registers maintained in such office or in any such office or agency of the Company in a Place
of Payment being herein sometimes referred to collectively as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration of Registered Securities and of transfers of Registered
Securities. The Security Register shall be in written form or any other form capable of being converted into written form within
a reasonable time. The Trustee, at its Corporate Trust Office, is hereby initially appointed "Security Registrar" for
the purpose of registering Registered Securities and transfers of Registered Securities on such Security Register as herein provided.
In the event that the Trustee shall cease to be Security Registrar, it shall have the right to examine the Security Register at
all reasonable times.

 

Subject to the provisions
of this Section 3.05, upon surrender for registration of transfer of any Registered Security of any series at any office or agency
of the Company in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver,
in the name of the designated transferee or transferees, one or more new Registered Securities of the same series, of any authorized
denominations and of a like aggregate principal amount, bearing a number not contemporaneously outstanding, and containing identical
terms and provisions.

 

Subject to the provisions
of this Section 3.05, at the option of the Holder, Registered Securities of any series may be exchanged for other Registered Securities
of the same series, of any authorized denomination or denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be exchanged at any such office or agency. Whenever any such
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. Unless otherwise specified with respect
to any series of Securities as contemplated by Section 3.01, Bearer Securities may not be issued in exchange for Registered Securities.

 

    	25

    	 

    
 

If (but only if) permitted
by the applicable Board Resolution and (subject to Section 3.03) set forth in the applicable Officers' Certificate, or in any indenture
supplemental hereto, delivered as contemplated by Section 3.01, at the option of the Holder, Bearer Securities of any series may
be exchanged for Registered Securities of the same series of any authorized denominations and of a like aggregate principal amount
and tenor, upon surrender of the Bearer Securities to be exchanged at any such office or agency, 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, any such permitted exchange may be effected if the Bearer Securities
are accompanied by payment in funds acceptable to the Company 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
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
10.02, interest represented by coupons shall be payable only upon presentation and surrender of those coupons at an office or agency
located outside the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any
such office or agency in a permitted exchange for a Registered Security of the same 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 relevant
Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related
proposed date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and interest or Defaulted Interest, as the case may be,
will 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 will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture. Whenever any Securities are so surrendered for exchange, the Company shall execute, and
the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

 

Notwithstanding the
foregoing, except as otherwise specified as contemplated by Section 3.01, any permanent global Security shall be exchangeable only
as provided in this paragraph. If the depositary for any permanent global Security is DTC, then, unless the terms of such global
Security expressly permit such global Security to be exchanged in whole or in part for definitive Securities, a global Security
may be transferred, in whole but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC, or to a successor to DTC
for such global Security selected or approved by the Company or to a nominee of such successor to DTC. If at any time DTC notifies
the Company that it is unwilling or unable to continue as depositary for the applicable global Security or Securities or if at
any time DTC ceases to be a clearing agency registered under the Exchange Act if so required by applicable law or regulation, the
Company shall appoint a successor depositary with respect to such global Security or Securities. If (x) a successor depositary
for such global Security or Securities is not appointed by the Company within 90 days after the Company receives such notice or
becomes aware of such unwillingness, inability or ineligibility, (y) an Event of Default has occurred and is continuing and the
beneficial owners representing a majority in principal amount of the applicable series of Securities represented by such global
Security or Securities advise DTC to cease acting as depositary for such global Security or Securities or (z) the Company, in its
sole discretion, determines at any time that all Outstanding Securities (but not less than all) of any series issued or issuable
in the form of one or more global Securities shall no longer be represented by such global Security or Securities, then the Company
shall execute, and the Trustee shall authenticate and deliver definitive Securities of like series, rank, tenor and terms in definitive
form in an aggregate principal amount equal to the principal amount of such global Security or Securities. If any beneficial owner
of an interest in a permanent global Security is otherwise entitled to exchange such interest for Securities of such series and
of like tenor and principal amount of another authorized form and denomination, as specified as contemplated by Section 3.01 and
provided that any applicable notice provided in the permanent global Security shall have been given, then without unnecessary delay
but in any event not later than the earliest date on which such interest may be so exchanged, the Company shall execute, and the
Trustee shall authenticate and deliver (subject to receipt of adequate instructions as to such beneficial ownership from DTC or
the Company) definitive Securities in aggregate principal amount equal to the principal amount of such beneficial owner's interest
in such permanent global Security. On or after the earliest date on which such interests may be so exchanged, such permanent global
Security shall be surrendered for exchange by DTC or such other depositary as shall be specified in the Company Order with respect
thereto to the Trustee, as the Company's agent for such purpose; provided, however, that no such exchanges may occur during a period
beginning at the opening of business 15 days before any selection of Securities to be redeemed and ending on the relevant Redemption
Date if the Security for which exchange is requested may be among those selected for redemption; and provided further that no Bearer
Security delivered in exchange for a portion of a permanent global Security shall be mailed or otherwise delivered to any location
in the United States. If a Registered Security is issued in exchange for any portion of a permanent global Security after the close
of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business
at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business
at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the
case may be, will 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 will 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 permanent global Security is payable in accordance with the provisions
of this Indenture.

 

    	26

    	 

    
 

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

 

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

 

No service charge shall
be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities,
other than exchanges pursuant to Section 3.04, 9.06, 11.07 or 13.05 not involving any transfer.

 

The Company or the
Trustee, as applicable, shall not be required (i) to issue, register the transfer of or exchange any Security if such Security
may be among those selected for redemption during a period beginning at the opening of business 15 days before selection of the
Securities to be redeemed under Section 11.03 and ending at the close of business on (A) if such Securities are issuable only as
Registered Securities, the day of the mailing of the relevant notice of redemption and (B) if such Securities are issuable as Bearer
Securities, the day of the first publication of the relevant notice of redemption or, if such Securities are also issuable as Registered
Securities and there is no publication, the mailing of the relevant notice of redemption, or (ii) to register the transfer of or
exchange any Registered Security so selected for redemption in whole or in part, except, in the case of any Registered Security
to be redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange any Bearer Security so selected for redemption
except that such a Bearer Security may be exchanged for a Registered Security of that series and like tenor, provided that such
Registered Security shall be simultaneously surrendered for redemption, or (iv) to issue, register the transfer of or exchange
any Security which has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Security
not to be so repaid.

Section
3.06          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 or the Company, together with, in proper
cases, such security or indemnity as may be required by the Company or the Trustee to save each of them or any agent of either
of them harmless, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security
of the same series and principal amount, containing identical terms and provisions and bearing a number not contemporaneously outstanding,
with coupons corresponding to the coupons, if any, appertaining to the surrendered Security.

 

If there shall be delivered
to the Company and to 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 reasonably 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 its request the Trustee shall authenticate and deliver, in lieu of any such
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 and principal amount, containing identical
terms and provisions and bearing a number not contemporaneously outstanding, with coupons 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
provisions of the previous two paragraphs, in case any such 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, with coupons 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, pay such Security or coupon; provided, however, that payment of principal of (and premium, if any),
any interest on and any Additional Amounts with respect to, Bearer Securities shall, except as otherwise provided in Section 10.02,
be payable only at an office or agency located outside the United States and, unless otherwise specified as contemplated by Section
3.01, any interest on Bearer Securities shall be payable only upon presentation and surrender of the coupons appertaining thereto.

 

Upon the issuance of
any new Security under this Section, 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
of any series with its coupons, if any, issued pursuant to this Section 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 an original additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Security and its coupons, if any, 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 and any
related Guarantees equally and proportionately with any and all other Securities of that series and their coupons, if any, duly
issued hereunder.

 

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

 

Section
3.07          Payment of Interest; Interest Rights Preserved.

 

Except as otherwise
specified with respect to a series of Securities in accordance with the provisions of Section 3.01, interest on any Registered
Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person
in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record
Date for the payment of such interest as follows: (i) to Holders having an aggregate principal amount of $1,000,000 or less of
Securities, by check mailed to such Holders at the address set forth in the Security Register; and (ii) to Holders having an aggregate
principal amount of more than $1,000,000 of Securities, either by check mailed to such Holders or, upon application by a Holder
to the Security Registrar not later than the Regular Record Date for the payment of such interest, by wire transfer in immediately
available funds to such Holder's account within the United States, which application shall remain in effect until the Holder notifies,
in writing, the Security Registrar to the contrary.

 

    	28

    	 

    
 

Unless otherwise provided
as contemplated by Section 3.01 with respect to the Securities of any series, payment of interest may be made, in the case of a
Bearer Security and at the Company's option, by transfer to an account maintained by the payee with a bank located outside the
United States.

 

Unless otherwise provided
as contemplated by Section 3.01, every permanent global Security will provide that interest, if any, payable on any Interest Payment
Date will be paid to DTC, Euroclear and/or Clearstream, as the case may be, with respect to that portion of such permanent global
Security held for its account by Cede & Co. or the Common Depositary, as the case may be, for the purpose of permitting such
party to credit the interest received by it in respect of such permanent global Security to the accounts of the beneficial owners
thereof.

 

In case a Bearer Security
of any series is surrendered in exchange for a Registered Security of such series after the close of business (at an office or
agency in a Place of Payment for such series) on any Regular Record Date and before the opening of business (at such office or
agency) on the next succeeding Interest Payment Date, such Bearer Security shall be surrendered without the coupon relating to
such Interest Payment Date and interest will not be payable on such Interest Payment Date in respect of the Registered Security
issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with
the provisions of this Indenture.

 

Except as otherwise
specified with respect to a series of Securities in accordance with the provisions of Section 3.01, any interest on any Registered
Security of any series that is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holder 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 in each case, as provided
in clause (1) or (2) below:

 

(1)          The
Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Registered Securities of such series
(or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount
of Defaulted Interest proposed to be paid on each Registered Security of such series and the date of the proposed payment (which
shall not be less than 20 days after such notice is received by the Trustee), and at the same time the Company shall deposit with
the Trustee an amount of money in the currency or currencies in which the Securities of such series are payable (except as otherwise
specified pursuant to Section 3.01 for the Securities of such series) 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 deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest
as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which
shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after
the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special
Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Registered Securities of such
series 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 in each Place of Payment, but such publications 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 Persons in whose names the Registered Securities of such
series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall
no longer be payable pursuant to the following clause (2). In case a Bearer Security of any series is surrendered at the office
or agency in a Place of Payment for such series in exchange for a Registered Security of such series after the close of business
at such office or agency on any Special Record Date and before the opening of business at such office or agency on the related
proposed date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the coupon relating to such
proposed date of payment and Defaulted Interest will not be payable on such proposed date of payment in respect of the Registered
Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture.

 

    	29

    	 

    
 

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

 

Subject to the foregoing
provisions of this Section and Section 3.05, 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.

 

Section
3.08          Persons Deemed Owners.

 

Prior to due presentment
of a Registered Security for registration of transfer, the Company, any Guarantor, the Trustee and any agent of the Company, any
Guarantor or the Trustee may treat the Person in whose name such Registered Security is registered as the owner of such Security
for the purpose of receiving payment of principal of (and premium, if any), and (subject to Sections 3.05 and 3.07) interest on,
such Registered Security and for all other purposes whatsoever, whether or not such Registered Security be overdue, and neither
the Company, any Guarantor, the Trustee nor any agent of the Company, any Guarantor or the Trustee shall be affected by notice
to the contrary.

 

Title to any Bearer
Security and any coupons appertaining thereto shall pass by delivery. The Company, any Guarantor, the Trustee and any agent of
the Company, any Guarantor or the Trustee may treat the Holder of any Bearer Security and the Holder 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 such Security or coupon be overdue, and neither the Company, any Guarantor, the Trustee nor any agent
of the Company, any Guarantor or the Trustee shall be affected by notice to the contrary.

 

    	30

    	 

    
 

None of the Company,
any Guarantor, 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 Security in global form or for maintaining,
supervising or reviewing any records relating to such beneficial ownership interests.

 

Notwithstanding the
foregoing, with respect to any global Security, nothing herein shall prevent the Company, any Guarantor, the Trustee, or any agent
of the Company, any Guarantor or the Trustee, from giving effect to any written certification, proxy or other authorization furnished
by any depositary, as a Holder, with respect to such global Security or impair, as between such depositary and owners of beneficial
interests in such global Security, the operation of customary practices governing the exercise of the rights of such depositary
(or its nominee) as Holder of such global Security.

 

Section
3.09          Cancellation.

 

All Securities and
coupons surrendered for payment, redemption, repayment at the option of the Holder, registration of transfer or exchange or for
credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee,
and any such Securities and coupons and Securities and coupons surrendered directly to the Trustee for any such purpose shall be
promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated
and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any
other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold, and all Securities so delivered shall be promptly canceled by the Trustee. If the Company shall so acquire
any of the Securities, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented
by such Securities unless and until the same are surrendered to the Trustee for cancellation. No Securities shall be authenticated
in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture.
Canceled Securities and coupons held by the Trustee shall be disposed of by the Trustee in accordance with its standard procedures,
and upon Company Request the Trustee shall deliver a certificate of such cancellation to the Company.

 

Section
3.10          Computation of Interest; CALCULATIONS.

 

Except as otherwise
specified as contemplated by Section 3.01 with respect to Securities of any series, interest on the Securities of each series shall
be computed on the basis of a 360-day year consisting of twelve 30-day months. The Company will be responsible for making calculations
called for under the Securities, including but not limited to determination of redemption price, premium, if any, and any additional
amounts or other amounts payable on the Securities. The Company will make the calculations in good faith and, absent manifest error,
its calculations will be final and binding on the Holders. The Company will provide a schedule of its calculations to the Trustee
when requested by the Trustee, and the Trustee is entitled to rely conclusively on the accuracy of the Company’s calculations
without independent verification.

REMEDIES

 

Section
5.01          Events of Default.

 

"Event of Default",
wherever used herein with respect to any particular series of Securities, means any one of the following events with respect to
such series of Securities (whatever the reason for such Event of Default and whether or not it shall be voluntary or involuntary
or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of
any administrative or governmental body), it being understood that an Event of Default with respect to a particular series of Securities

by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities
a written notice, in each case received by the Company (and the Trustee, if applicable), specifying such default and requiring

under any agreement or other instrument under which the Company or any Subsidiary then has outstanding indebtedness for money borrowed
in excess of $25,000,000 in the aggregate for the Company and/or any Subsidiary, whether such indebtedness now exists or shall
hereafter be created (but excluding intercompany indebtedness), and either (a) such default results from the failure to pay any
such indebtedness at its stated final maturity or (b) such default has caused the holder of such indebtedness to declare such indebtedness
to be due and payable prior to its stated final maturity, unless, within 30 days after there has been given, by registered or certified
mail, a written notice of default under this clause (5) to the Company by the Trustee or to the Company and the Trustee by the

Section
5.02          Acceleration of Maturity; Rescission and Annulment.

 

If an Event of Default
with respect to Securities of any series at the time Outstanding other than an Event of Default specified in clause (6) or (7)
of Section 5.01 occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in principal
amount of the Outstanding Securities of that series may declare the principal (or, if any Securities are Original Issue Discount
Securities or Indexed Securities, such portion of the principal as may be specified in the terms thereof) of all the Securities
of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders),
and upon any such declaration such principal or specified portion thereof shall become immediately due and payable.

 

If an Event of Default
specified in clause (6) or (7) of Section 5.01 occurs, all unpaid principal of and accrued interest on the Outstanding Securities
of that series (or such lesser amount as may be provided for in the Securities of such series) shall ipso facto become and be immediately
due and payable without any declaration or other act on the part of the Trustee or any Holder of any Security of that series.

 

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

 

(1)          the
Company has paid or deposited with the Trustee a sum sufficient to pay in the currency or currencies in which the Securities of
such series are payable (except as otherwise specified pursuant to Section 3.01 for the Securities of such series):

 

(A)          all
overdue installments of interest on and any Additional Amounts payable in respect of all Outstanding Securities of that series
and any related coupons,

 

(B)          the
principal of (and premium, if any, on) any Outstanding Securities of that series which have become due otherwise than by such declaration
of acceleration and interest thereon at the rate or rates borne by or provided for in such Securities,

 

(C)          to
the extent that payment of such interest is lawful, interest upon overdue installments of interest and any Additional Amounts at
the rate or rates borne by or provided for in such Securities, and

 

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

 

(2)          all
Events of Default with respect to Securities of that series, other than the nonpayment of the principal of (or premium, if any)
or interest on Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived
as provided in Section 5.13.

 

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

 

    	35

    	 

    
 

Section
5.03          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 or Additional Amounts, if any, on any Security of any series and any related
coupon when such interest or Additional Amount becomes due and payable and such default continues for a period of 30 days, or

 

(2)          default
is made in the payment of the principal of (or premium, if any, on) any Security of any series at its Maturity,

 

then the Company will,
upon demand by the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities of such series and coupons, the
whole amount then due and payable on such Securities and coupons for principal (and premium, if any) and interest and Additional
Amount, with interest upon any overdue principal (and premium, if any) and, to the extent that payment of such interest shall be
legally enforceable, upon any overdue installments of interest or Additional Amounts, if any, at the rate or rates borne by or
provided for in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses
of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

 

If the Company fails
to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute
a judicial proceeding for the collection of the sums so due and unpaid, 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 of such series and collect the moneys
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 of such series, 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 related coupons by such appropriate judicial proceedings
as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant
or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

 

Section
5.04          Trustee May File Proofs of Claim.

 

In case of the pendency
of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company, a Guarantor or any other obligor upon the Securities or the property of the Company, a Guarantor
or such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities of any series 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, Guarantor or obligor for the payment of overdue principal, premium, if any, or interest) shall
be entitled and empowered, by intervention in such proceeding or otherwise:

 

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

 

    	36

    	 

    
 

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

 

and any custodian,
receiver, assignee, trustee, liquidator, sequestrator (or other similar official) in any such judicial proceeding is hereby authorized
by each Holder of Securities of such series and 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, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee and any predecessor Trustee, their agents and counsel, and any
other amounts due the Trustee or any predecessor Trustee under Section 6.06. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section
6.06 hereof out of the estate in any such bankruptcy, insolvency or similar proceeding, shall be denied for any reason, payment
of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and
other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization
or arrangement or otherwise. The Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar
official and be a member of a creditors' or other similar committee.

 

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

 

Section
5.05          Trustee May Enforce Claims Without Possession of Securities or
Coupons.

 

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

 

Section
5.06          Application of Money Collected.

 

If after an Event of
Default any moneys or properties distributable in respect of the Company’s or any Guarantor’s obligations under this
Indenture, or any money or property collected by the Trustee pursuant to this Article shall be applied in the following order,
at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if
any) or interest and any Additional Amounts, upon presentation of the Securities or coupons, or both, as the case may be, and the
notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

 

FIRST: To the payment
of all amounts due the Trustee and any predecessor Trustee under Section 6.06;

 

    	37

    	 

    
 

SECOND: To the payment
of the amounts then due and unpaid upon the Securities and coupons for principal (and premium, if any) and interest and any Additional
Amounts payable, in respect of which or for the benefit of which such money has been collected, ratably, without preference or
priority of any kind, according to the aggregate amounts due and payable on such Securities and coupons for principal (and premium,
if any), interest and Additional Amounts, respectively; and

 

THIRD: To the payment
of the remainder, if any, to the Company.

 

Section
5.07          Limitation on Suits.

 

No Holder of any Security
of any series or any related coupon shall have any right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

 

(1)          such
Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that
series;

 

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

 

(3)          such
Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to the Trustee against the costs, expenses and
liabilities to be incurred in compliance with such request;

 

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

 

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

 

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

 

Section
5.08          Unconditional Right of Holders to Receive Principal, Premium, if
any, Interest and Additional Amounts.

 

Notwithstanding any
other provision in this Indenture, the Holder of any Security or coupon shall have the right which is absolute and unconditional
to receive payment of the principal of (and premium, if any) and (subject to Sections 3.05 and 3.07) interest on, and any Additional
Amounts in respect of, such Security or payment of such coupon on the respective due dates expressed in such Security or coupon
(or, in the case of redemption or repayment, on the Redemption Date or the Repayment Date) and to institute suit for the enforcement
of any such payment or for the enforcement of any applicable conversion right in the Securities, and such rights shall not be impaired
without the consent of such Holder.

 

Section
5.09          Restoration of Rights and Remedies.

 

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

 

    	38

    	 

    
 

Section
5.10          Rights and Remedies Cumulative.

 

Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons in the last paragraph
of Section 3.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities or coupons
is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion
or employment of any other appropriate right or remedy.

 

Section
5.11          Delay or Omission Not Waiver.

 

No delay or omission
of the Trustee or of any Holder of any 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 the Holders may be exercised from time to time, and as often as may
be deemed expedient, by the Trustee or by the Holders of Securities or coupons, as the case may be.

 

Section
5.12          Control by Holders of Securities.

 

The Holders of not
less than a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the
Trustee with respect to the Securities of such series, provided that

 

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

 

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

 

(3)          the
Trustee need not take any action which might involve it in personal liability or be unduly prejudicial to the Holders of Securities
of such series not joining therein (it being understood that the Trustee does not have an affirmative duty to ascertain whether
or not any such directions are unduly prejudicial to such Holders).

 

Section
5.13          Waiver of Past Defaults.

 

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

 

(1)          in
the payment of the principal of (or premium, if any) or interest on or Additional Amounts payable in respect of any Security of
such series or any related coupons,

 

(2)          in
the conversion or exchange of the Securities in accordance with their terms, or

 

    	39

    	 

    
 

(3)          in
respect of a covenant or provision hereof which under Article Nine may not be modified or amended without the consent of the Holder
of each Outstanding Security of such series affected.

 

Upon any such waiver,
such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent
thereon.

 

Section
5.14          Waiver of Usury, Stay or Extension Laws.

 

Each of the Company
and each Guarantor covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or
in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at
any time hereafter in force, which may affect the covenants or the performance of this Indenture; and each of the Company and each
Guarantor hereby 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 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 the Outstanding Securities, or to any
suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest on or Additional
Amounts payable in respect of any Security on or after the respective Stated Maturities expressed in such Security (or, in the
case of redemption or repayment, on or after the Redemption Date or the Repayment Date) or for the enforcement of any applicable
conversion right in the Securities.

of the principal of (or premium, if any) or interest on or any Additional Amounts with respect to any Security of such series,
or in the payment of any sinking fund installment with respect to the Securities of such series, the Trustee shall be protected

such notice is in the interests of the Holders of the Securities and coupons of such series; and provided further that in the case
of any default or breach of the character specified in Section 5.01(4) with respect to the Securities and coupons of such series,
no such notice to Holders shall be given until at least 60 days after the occurrence thereof. For the purpose of this Section,

(15)          the
Trustee may request that the Company or any Guarantor deliver an Officers’ Certificate setting forth the names of individuals
and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture.

 

The
Trustee shall have the rights and obligations specified in Section 315(a), 315(c) and 315(d) of the Trust Indenture Act. Every
provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee is subject
to the provisions of this Section, whether or not expressly provided. The Trustee shall not be required to give any bond
or surety in respect of the performance of its powers or duties hereunder. The Trustee shall not be required to expend or risk
its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity
against such risk or liability is not reasonably assured to it.

 

Except during the continuance
of an Event of Default, the Trustee undertakes to perform only such duties as are specifically set forth in this Indenture, and
no implied covenants or obligations shall be read into this Indenture against the Trustee.

Section
6.03          Not Responsible for Recitals or Issuance of Securities.

 

The recitals contained
herein and in the Securities and Guarantees, except the Trustee's certificate of authentication, and in any coupons shall be taken
as the statements of the Company and Guarantors, and neither the Trustee nor any Authenticating Agent assumes any responsibility
for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities
or Guarantees or coupons, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture,
authenticate the Securities and perform its obligations hereunder and that the statements made by it in any Statement of Eligibility
on Form T-1 supplied to the Company are true and accurate. Neither the Trustee nor any Authenticating Agent shall be accountable
for the use or application by the Company of Securities or the proceeds thereof or for any funds received and disbursed in accordance
with this Indenture. The Trustee shall have no responsibility or liability with respect to any information, statement or recital
in any offering memorandum, prospectus, prospectus supplement or other disclosure material prepared or distributed with respect
to the issuance of any series of the Securities.

 

Section
6.04          May Hold Securities.

 

The Trustee, any Paying
Agent, Security Registrar, Authenticating Agent or any other agent of the Company, in its individual or any other capacity, may
become the owner or pledgee of Securities and coupons and, subject to TIA Sections 310(b) and 311, may otherwise deal with the
Company with the same rights it would have if it were not Trustee, Paying Agent, Security Registrar, Authenticating Agent or such
other agent.

 

Section
6.05          Money Held in Trust.

 

Money held by the Trustee
in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company.

 

Section
6.06          Compensation and Reimbursement.

 

The Company and each
Guarantor agrees:

 

(1)          to
pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (which compensation shall
not be limited by any provision of law in regard to the compensation of a trustee of an express trust) as agreed with the Company
in writing from time to time;

 

(2)          except
as otherwise expressly provided herein, to reimburse each of the Trustee and any predecessor Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including
the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement
or advance as may be attributable to its negligence or bad faith; and

 

(3)          to
indemnify each of the Trustee and any predecessor Trustee and their directors, officers, agents and employees for, and to hold
them harmless against, any loss, liability or expense incurred without negligence or bad faith on its own part, arising out of
or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses (including
without limitation reasonable attorneys' fees and costs) of defending themselves against any claim or liability in connection with
the exercise or performance of any of its powers or duties hereunder.

 

    	43

    	 

    
 

When the Trustee incurs
expenses or renders services in connection with an Event of Default specified in Section 5.01(6) or Section 5.01(7), the expenses
(including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute
expenses of administration under any applicable Federal or state bankruptcy, insolvency or other similar law.

 

As security for the
performance of the obligations of the Company under this Section, the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held in trust for the payment of principal of (or premium,
if any) or interest on particular Securities or any coupons.

 

“Trustee”
for the purposes of this Section 6.06 shall include any predecessor Trustee and the Trustee in each of its capacities hereunder
and each agent, custodian and other person employed to act hereunder; provided, however, that the negligence or willful misconduct
of any Trustee hereunder shall not affect the rights of any other Trustee hereunder, except in the case of a successor Trustee
that becomes Trustee pursuant to Section 6.10.

 

The provisions of this
Section shall survive the termination of this Indenture (and shall survive the resignation or removal of the Trustee pursuant to
Section 6.08).

 

Section
6.07          Eligibility of Trustee; Conflicting Interests.

 

There shall at all
times be a Trustee hereunder which shall be eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined capital
and surplus of at least $50,000,000. If such Trustee publishes reports of condition at least annually, pursuant to law or the requirements
of Federal, State, Territorial or District of Columbia supervising or examining authority, then for the purposes of this Section,
the combined capital and surplus of such Trustee shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions
of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

 

There shall be excluded
from the operation of TIA Section 310(b)(i) any series of Securities under this Indenture or any indenture or indentures under
which other securities or certificates of interest or participation in other securities of the Company or any of the Guarantors
are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(i) are met.

 

Section
6.08          Resignation and Removal; Appointment of Successor.

 

(a)          No
resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective
until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 6.09.

 

(b)          The
Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company.
If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving
of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

 

(c)          The
Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal
amount of the Outstanding Securities of such series delivered to the Trustee and to the Company.

 

    	44

    	 

    
 

(d)          If
at any time:

 

(1)          the
Trustee shall fail to comply with the provisions of TIA Section 310(b) after written request therefor by the Company or by any
Holder of a Security who has been a bona fide Holder of a Security for at least six months, or

 

(2)          the
Trustee shall cease to be eligible under Section 6.07 and shall fail to resign after written request therefor by the Company or
by any Holder of a Security who has been a bona fide Holder of a Security for at least six months, or

 

(3)          the
Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property
shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose
of rehabilitation, conservation or liquidation,

 

then, in any such case,
(i) the Company by or pursuant to a Board Resolution may remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security who has been a bona fide Holder of a Security for at
least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for
the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.

 

(e)          If
the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any
cause with respect to the Securities of one or more series, the Company shall promptly appoint a successor Trustee or Trustees
with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with
respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect
to the Securities of any particular series). If, within one year after such resignation, removal or incapability, or the occurrence
of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a
majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, and
to any successor Trustee appointed by the Company with respect to such Securities, the successor Trustee so appointed by the Holders
shall, forthwith upon its acceptance of such appointment, become the successor Trustee with respect to the Securities of such series
and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities
of any series shall have been so appointed by the Company or the Holders of Securities and accepted appointment in the manner hereinafter
provided, any Holder of a Security who has been a bona fide Holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor
Trustee with respect to Securities of such series.

 

(f)          The
Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and
each appointment of a successor Trustee with respect to the Securities of any series in the manner provided for notices to the
Holders of Securities in Section 1.06. Each notice shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

 

Section
6.09          Acceptance of Appointment by Successor.

 

(a)          In
case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the
Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges and other due but unpaid amounts owing
to it hereunder, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of
the retiring Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such
retiring Trustee hereunder, subject nevertheless to its claim, if any, provided for in Section 6.06.

 

    	45

    	 

    
 

(b)          In
case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the
Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and
deliver an indenture supplemental hereto, pursuant to Article Nine hereof, wherein each successor Trustee shall accept such appointment
and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each
successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to
all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee
is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee,
it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same
trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal
of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect
to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company
or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates.

 

(c)          Upon
request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section,
as the case may be.

 

(d)          No
successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified
and eligible under this Article.

 

(e)          A
successor Trustee shall deliver notice of its succession to each Holder of the Securities of such series for which it becomes trustee.

 

Section
6.10          Merger, Conversion, Consolidation or Succession to Business.

 

Any entity into which
the Trustee may be merged or converted or with which it may be consolidated, or any entity resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any entity succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder, provided such entity shall be otherwise qualified and
eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties
hereto. In case any Securities or coupons shall have been authenticated, but not delivered, by the Trustee then in office, any
successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities
or coupons so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities or coupons.
In case any Securities or coupons shall not have been authenticated by such predecessor Trustee, any such successor Trustee may
authenticate and deliver such Securities or coupons, in either its own name or that of its predecessor Trustee, with the full force
and effect which this Indenture provides for the certificate of authentication of the Trustee.

 

    	46

    	 

    
 

Section
6.11          Appointment of Authenticating Agent.

 

At any time when any
of the Securities remain Outstanding, the Trustee may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon exchange,
registration of transfer or partial redemption or repayment thereof, and Securities so authenticated shall be entitled to the benefits
of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Any such appointment
shall be evidenced by an instrument in writing signed by a Responsible Officer of the Trustee, a copy of which instrument shall
be promptly furnished to the Company. Wherever reference is made in this Indenture to the authentication and delivery of Securities
by the Trustee or the Trustee's certificate of authentication, such reference shall be deemed to include authentication and delivery
on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a bank or trust company
or corporation organized and doing business and in good standing under the laws of the United States or of any State or the District
of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by Federal or State authorities. If such Authenticating Agent publishes reports
of condition at least annually, pursuant to law or the requirements of the aforesaid supervising or examining authority, then for
the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so published. In case at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

 

Any entity into which
an Authenticating Agent may be merged or converted or with which it may be consolidated, or any entity resulting from any merger,
conversion or consolidation to which such Authenticating Agent shall be a party, or any entity succeeding to the corporate agency
or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such entity shall
be otherwise eligible under this Section, without the execution or filing of any paper or further act on the part of the Trustee
or the Authenticating Agent.

 

An Authenticating Agent
for any series of Securities may at any time resign by giving written notice of resignation to the Trustee for such series and
to the Company. The Trustee for any series of Securities may at any time terminate the agency of an Authenticating Agent by giving
written notice of termination to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon
such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions
of this Section, the Trustee for such series may appoint a successor Authenticating Agent which shall be acceptable to the Company
and shall give notice of such appointment to all Holders of Securities of the series with respect to which such Authenticating
Agent will serve in the manner set forth in Section 1.06. 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 herein. No successor Authenticating Agent shall be appointed unless eligible under the provisions
of this Section.

 

    	47

    	 

    
 

The Company agrees
to pay to each Authenticating Agent from time to time reasonable compensation including reimbursement of its reasonable expenses
for its services under this Section.

 

If an appointment with
respect to one or more series is made 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 substantially in the following
form:

 

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

by the Company, bear a notation as to any matter provided for in such supplemental indenture. If the Company shall so determine,
new Securities of any series so modified as to conform, in the opinion of the Trustee and the Company, to any such supplemental
indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding
Securities of such series.

COVENANTS

 

Section
10.01          Payment of Principal, Premium, if any, Interest and Additional
Amounts.

 

The Company covenants
and agrees for the benefit of the Holders of each series of Securities that it will duly and punctually pay the principal of (and
premium, if any) and interest on and any Additional Amounts payable in respect of the Securities of that series in accordance with
the terms of such series of Securities, any coupons appertaining thereto and this Indenture. Unless otherwise specified as contemplated
by Section 3.01 with respect to any series of Securities, any interest due on and any Additional Amounts payable in respect of
Bearer Securities on or before Maturity, other than Additional Amounts, if any, payable as provided in Section 10.11 in respect
of principal of (or premium, if any, on) such a Security, shall be payable only upon presentation and surrender of the several
coupons for such interest installments as are evidenced thereby as they severally mature. Unless otherwise specified with respect
to Securities of any series pursuant to Section 3.01, at the option of the Company, all payments of principal may be paid by check
to the Holder of the Registered Security or other person entitled thereto against surrender of such Security.

 

Section
10.02          Maintenance of Office or Agency.

 

If Securities of a
series are issuable only as Registered Securities, the Company shall maintain in each Place of Payment for any series of Securities
an office or agency where Securities of that series may be presented or surrendered for payment or conversion, where Securities
of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company
in respect of the Securities of that series and this Indenture may be served. If Securities of a series are issuable as Bearer
Securities, the Company will maintain: (A) in the Borough of Manhattan, The City of New York, an office or agency where any Registered
Securities of that series may be presented or surrendered for payment or conversion, where any Registered Securities of that series
may be surrendered for registration of transfer, where Securities of that series may be surrendered for exchange, where notices
and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served and where Bearer
Securities of that series and related coupons may be presented or surrendered for payment or conversion in the circumstances described
in the following paragraph (and not otherwise); (B) subject to any laws or regulations applicable thereto in a Place of Payment
for that series which is located outside the United States, an office or agency where Securities of that series and related coupons
may be presented and surrendered for payment (including payment of any Additional Amounts payable on Securities of that series
pursuant to Section 10.11) or conversion; provided, however, that if the Securities of that series are listed on the Luxembourg
Stock Exchange or any other stock exchange located outside the United States and such stock exchange shall so require, the Company
will maintain a Paying Agent for the Securities of that series in Luxembourg or any other required city located outside the United
States, as the case may be, so long as the Securities of that series are listed on such exchange; and (C) if the Securities of
such series are or may also be issued in part as, or may be converted to, Registered Securities, subject to any laws or regulations
applicable thereto in a Place of Payment for that series located outside the United States, an office or agency where any Registered
Securities of that series may be surrendered for registration of transfer, where Securities of that series may be surrendered for
exchange and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may
be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of each
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 that series and the related coupons may be presented and surrendered
for payment (including payment of any Additional Amounts payable on Bearer Securities of that series pursuant to Section 10.11)
or conversion at the offices specified in the Security, in London, England, and the Company hereby appoints the same as its agent
to receive such respective presentations, surrenders, notices and demands, and the Company hereby appoints the Trustee its agent
to receive all such presentations, surrenders, notices and demands. Nothing herein shall oblige the Trustee to maintain any such
office or agency on behalf of the Company in any such Place of Payment, other than the Corporate Trust Office.

 

    	52

    	 

    
 

Unless otherwise specified
with respect to any Securities pursuant to Section 3.01, no payment of principal, premium or interest on or Additional Amounts
in respect of Bearer Securities shall be made at any office or agency of the Company 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,
that, if amounts owing with respect to any Bearer Securities of a series are payable in Dollars, payment of principal of and any
premium and interest on any Bearer Security (including any Additional Amounts payable on Securities of such series pursuant to
Section 10.11) shall be made at the office of the Company's Paying Agent in the Borough of Manhattan, The City of New York, if
(but only if) payment in Dollars of the full amount of such principal, premium, interest or Additional Amounts, as the case may
be, at all offices or agencies outside the United States maintained for the purpose by the Company in accordance with this Indenture,
is illegal or effectively precluded by exchange controls or other similar restrictions.

 

The Company may 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 of such purposes, and may from time to time rescind any such designation; 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 accordance with the
requirements set forth above for Securities of any series for such purposes. The Company will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location of any such other office or agency. Unless otherwise
specified with respect to any Securities pursuant to Section 3.01 with respect to a series of Securities, the Company hereby designates
as a Place of Payment for each series of Securities the office or agency of the Company in the continental United States, and initially
appoints the Trustee at its Corporate Trust Office as Paying Agent and as its agent to receive all such presentations, surrenders,
notices and demands.

 

Unless otherwise specified
with respect to any Securities pursuant to Section 3.01, 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 the
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
10.03          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 any Securities and any related coupons, it will, on or before
each due date of the principal of (and premium, if any), or interest on or Additional Amounts in respect of, any of the Securities
of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the currency or currencies
in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Securities of
such series) sufficient to pay the principal (and premium, if any) or interest or Additional Amounts so becoming due until such
sums shall be paid to such Persons or otherwise disposed of as herein provided, and will promptly notify the Trustee of its action
or failure so to act.

 

    	53

    	 

    
 

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

 

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

 

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

 

(2)          give
the Trustee notice of any default by the Company or a Guarantor (or any other obligor upon the Securities) in the making of any
such payment of principal (and premium, if any) or interest; 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 by such Paying Agent, such sums to
be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon
such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to
such sums.

 

Except as otherwise
provided in the Securities of any series (and subject to any abandoned property laws that may be applicable), any money deposited
with the Trustee in trust or with any Paying Agent, or then held by the Company in trust, for the payment of the principal of (and
premium, if any) or interest on, or any Additional Amounts in respect of, any Security of any series and remaining unclaimed for
two years after such principal (and premium, if any), interest or Additional Amounts has become due and payable shall be paid to
the Company upon Company Request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company and any Guarantor(s) for payment of such principal
of (and premium, if any) or interest on, or any Additional Amounts in respect of, any Security, without interest thereon, and all
liability of the Trustee or such Paying Agent with respect to such 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, notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Company.

 

Section
10.04           [Reserved].

 

Section
10.05          Existence.

 

Subject to Article
Eight, the Company and each Guarantor will do or cause to be done all things necessary to preserve and keep in full force and effect
its corporate existence, rights (charter and statutory) and franchises; provided, however, that the Company and each Guarantor
shall not be required to preserve any right or franchise if its Board of Directors shall determine that the preservation thereof
is no longer desirable in the conduct of business and that the loss thereof is not disadvantageous in any material respect to the
Holders.

Section
10.06          Maintenance of Properties.

 

The Company will, and
will cause each of its Subsidiaries to, cause all of its material properties used or useful in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as
in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that nothing in this Section shall prevent the Company or any Subsidiary from discontinuing
the operation and maintenance of any such properties if such discontinuance is, in the judgment of the Company or the Subsidiary,
desirable in the conduct of its business and not disadvantageous in any material respect to the Holders.

 

Section
10.07          Insurance.

 

The Company will, and
will cause each of its Subsidiaries to, keep all of its insurable properties adequately insured against loss or damage with insurers
of recognized responsibility in commercially reasonable amounts and types.

 

Section
10.08          Payment of Taxes and Other Claims.

 

The Company will pay
or discharge or cause to be paid or discharged, before the same shall become delinquent, (1) all material taxes, assessments and
governmental charges levied or imposed upon it or any Subsidiary or upon the income, profits or property of the Company or any
Subsidiary, and (2) all material lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon
the property of the Company or any Subsidiary unless such lien would not have a material adverse effect upon such property; provided,
however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim (i) whose amount, applicability or validity is being contested in good faith by appropriate proceedings or (ii)
for which the Company has set apart and maintains an adequate reserve.

 

Section
10.09          Commission and Other Reports to the Trustee.

 

(a)          The
Company shall ensure delivery to the Trustee within 15 calendar days after it files such annual and quarterly reports, information,
documents and other reports with the Commission, copies of its annual report and of the information, documents and other reports
(or copies of such portions of any of the foregoing as the Commission may by rules and regulations prescribe) which the Company
is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act in accordance with TIA Section 314(a).
In the event the Company is at any time no longer subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, it shall continue to provide the Trustee with reports containing substantially the same information as would have been required
to be filed with the Commission if the Company had continued to have been subject to such reporting requirements. In such event,
such reports shall be provided at the times the Company would have been required to provide reports if it had continued to have
been subject to such reporting requirements. The Company also shall comply with the other provisions of TIA Section 314(a). Delivery
of such reports, information and documents to the Trustee is for informational purposes only and the Trustee's receipt of such
reports, information and documents shall not constitute constructive notice of any information contained therein or determinable
from information contained therein, including the Company's compliance with any of its covenants hereunder (as to which the Trustee
is entitled to rely on Officers' Certificates). The Trustee shall have no duty or responsibility to review such reports, information
or documents. In the event that the Company shall provide the Trustee with any such report, information or document and shall not
have filed such report, information or document on the Commission's Electronic Data Gathering, Analysis and Retrieval system, the
Company shall promptly mail or make available copies of such report, information or document to each Holder (other than reports
provided solely pursuant to TIA Section 314(a)).

 

    	55

    	 

    
 

(b)          The
Company intends to file the reports, information and documents referred to in Section 10.09(a) with the Commission in electronic
form pursuant to Regulation S-T of the Commission using the Commission's Electronic Data Gathering, Analysis and Retrieval system.
Compliance with the foregoing shall constitute delivery by the Company of such reports, information and documents to the Trustee
in compliance with the provisions of Section 10.09(a) and TIA Section 314(a). The Trustee shall have no duty to search for or obtain
any electronic or other filings that the Company makes with the Commission, regardless of whether such filings are periodic, supplemental
or otherwise. Delivery of the reports, information and documents to the Trustee pursuant to this Section 10.09(b) shall be solely
for the purposes of compliance with this Section 10.09(b) and with TIA Section 314(a). The Trustee's receipt of such reports, information
and documents shall not constitute notice to it of the content thereof or of any matter determinable from the content thereof,
including the Company's compliance with any of its covenants hereunder, as to which the Trustee is entitled to rely on Officers'
Certificates.

 

Section
10.10          Statement as to Compliance.

 

The Company and each
Guarantor will deliver to the Trustee, within 120 days after the end of each fiscal year, a brief certificate from the principal
executive officer, principal financial officer or principal accounting officer as to his or her knowledge of its compliance with
all conditions and covenants under this Indenture and, in the event of any noncompliance, specifying such noncompliance and the
nature and status thereof. For purposes of this Section 10.10, such compliance shall be determined without regard to any period
of grace or requirement of notice under this Indenture.

 

Section
10.11          Additional Amounts.

 

If any Securities of
a series provide for the payment of Additional Amounts, the Company will pay to the Holder of any Security of such series or any
coupon appertaining thereto Additional Amounts as may be specified as contemplated by Section 3.01. Whenever in this Indenture
there is mentioned, in any context except in the case of Section 5.02(1), the payment of the principal of or any premium or interest
on, or in respect of, any Security of any series or payment of any related 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 pursuant to Section 3.01 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 provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention
is not made.

 

    	56

    	 

    
 

Except as otherwise
specified as contemplated by Section 3.01, 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 that series of Securities (or if the Securities of that series
will not bear interest prior to Maturity, the first day on which a payment of principal and any premium is made), and at least
10 days prior to each date of payment of principal and any premium or interest if there has been any change with respect to the
matters set forth in the below-mentioned Officers' Certificate, the Company will furnish the Trustee and the Company's principal
Paying Agent or Paying Agents, if other than the Trustee, with an Officers' Certificate instructing the Trustee and such Paying
Agent or Paying Agents whether such payment of principal of and any premium or interest on the Securities of that series shall
be made to Holders of Securities of that series or any related coupons who are not United States persons without withholding for
or on account of any tax, assessment or other governmental charge described in the Securities of the series. If any such withholding
shall be required, then such Officers' Certificate shall specify by country the amount, if any, required to be withheld on such
payments to such Holders of Securities of that series or related coupons and the Company will pay to the Trustee or such Paying
Agent the Additional Amounts required by the terms of such Securities. In the event that the Trustee or any Paying Agent, as the
case may be, shall not so receive the above-mentioned certificate, then the Trustee or such Paying Agent shall be entitled (i)
to assume that no such withholding or deduction is required with respect to any payment of principal, premium, if any, or interest
with respect to any Securities of a series or related coupons until it shall have received a certificate advising otherwise and
(ii) to make all payments of principal, premium, if any, and interest with respect to the Securities of a series or related coupons
without withholding or deductions until otherwise advised. 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 or in reliance on any Officers' Certificate furnished
pursuant to this Section or in reliance on the Company's not furnishing such an Officers' Certificate.

 

Section
10.12          Waiver of Certain Covenants.

 

The Company may omit
in any particular instance to comply with any term, provision or condition set forth in Sections 10.05 to 10.11, inclusive, if
before or after the time for such compliance the Holders of at least a majority in principal amount of all outstanding Securities
of such series, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such covenant
or condition, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly waived,
and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such
term, provision or condition shall remain in full force and effect.

 

Article
XI.

REDEMPTION OF SECURITIES

 

Section
11.01          Applicability of Article.

 

Securities of any series
which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified
as contemplated by Section 3.01 for Securities of any series) in accordance with this Article.

 

Section
11.02          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 less than all of the Securities of any series, the Company shall, at least 15 days prior to the giving of the
notice of redemption in Section 11.04 (unless a shorter notice shall be satisfactory to the Trustee, for purposes of the Trustee's
administrative convenience), notify the Trustee in writing of such Redemption Date and of the principal amount of Securities of
such series to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers'
Certificate evidencing compliance with such restriction.

 

    	57

    	 

    
 

Section
11.03          Selection by Trustee of Securities to Be Redeemed.

 

If less than all the
Securities of any series issued on the same day with the same terms are to be redeemed, and the Securities are global Securities,
the Securities to be redeemed will be selected in accordance with Applicable Procedures. If the Securities are not global Securities,
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 issued on such date with the same terms 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 (equal
to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the principal amount
of Securities of such series of a denomination larger than the minimum authorized denomination for Securities of that series.

 

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 Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which
has been or is to be redeemed.

 

Section
11.04          Notice of Redemption.

 

Notice of redemption
shall be given in the manner provided in Section 1.06, not less than 30 days nor more than 60 days prior to the Redemption Date,
unless a shorter period is specified by the terms of such series established pursuant to Section 3.01, to each Holder of Securities
to be redeemed, but failure to give such notice in the manner herein provided to the Holder of any Security 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 such Security or portion thereof.

 

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

 

All notices of redemption
shall state:

 

(1)          the
Redemption Date,

 

(2)          the
Redemption Price (or manner of calculation if not then known), accrued interest to the Redemption Date payable as provided in Section
11.06, if any, and Additional Amounts, if any,

 

(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 will receive, without a charge, a new Security or Securities of authorized denominations
for the principal amount thereof remaining unredeemed,

 

    	58

    	 

    
 

(5)          that
on the Redemption Date the Redemption Price and accrued interest to the Redemption Date payable as provided in Section 11.06, if
any, will become due and payable upon each such Security, or the 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 of Payment 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 accrued interest, if
any, or for conversion,

 

(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 reasonably satisfactory to the Company, the Trustee for such series
and any Paying Agent is furnished,

 

(9)          if
Bearer Securities of any series are to be redeemed and any Registered Securities of such series are not to be redeemed, and if
such Bearer Securities may be exchanged for Registered Securities not subject to redemption on this Redemption Date pursuant to
Section 3.05 or otherwise, the last date, as determined by the Company, on which such exchanges may be made,

 

(10)          the
CUSIP number of such Security, if any, and

 

(11)          if
applicable, that a Holder of Securities who desires to convert Securities for redemption must satisfy the requirements for conversion
contained in such Securities, the then existing conversion price or rate, and the date and time when the option to convert shall
expire.

 

Notice of redemption
of Securities to be redeemed 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
11.05          Deposit of Redemption Price.

 

At least one Business
Day prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting
as its own Paying Agent, which it may not do in the case of a sinking fund payment under Article Twelve, segregate and hold in
trust as provided in Section 10.03) an amount of money in the currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 3.01 for the Securities of such series) sufficient to pay on the Redemption
Date the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date, unless otherwise specified
pursuant to Section 3.01 or in the Securities of such series) accrued interest on, all the Securities or portions thereof which
are to be redeemed on that date.

 

    	59

    	 

    
 

Section
11.06          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 in the currency or currencies in which the Securities of such series are payable (except as otherwise specified
pursuant to Section 3.01 for the Securities of such series) (together with accrued interest, if any, to the Redemption Date), and
from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities
shall, if the same were interest-bearing, 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 accrued interest, if any, to the Redemption Date; provided, however,
that installments of interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable
only at an office or agency located outside the United States (except as otherwise provided in Section 10.02) and, unless otherwise
specified as contemplated by Section 3.01, only upon presentation and surrender of coupons for such interest; and provided further
that, except as otherwise specified in or pursuant to this Indenture or the Registered Securities of a 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 relevant Record Dates
according to their terms and the provisions of Section 3.07.

 

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 interest represented by coupons
shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 10.02)
and, unless otherwise specified as contemplated by Section 3.01, only upon presentation and surrender of those coupons.

 

If any Security called

SINKING FUNDS

 

Section
12.01          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 specified as contemplated
by Section 3.01 for Securities of such series.

 

    	60

    	 

    
 

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 such Securities of any series
is herein referred to as an "optional sinking fund payment". If provided for by the terms of any Securities of any series,
the cash amount of any mandatory sinking fund payment may be subject to reduction as provided in Section 12.02. Each sinking fund
payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series.

 

Section
12.02          Satisfaction of Sinking Fund Payments with Securities.

 

The Company may, in
satisfaction of all or any part of any mandatory sinking fund payment with respect to the Securities of a series, (1) deliver Outstanding
Securities of such series (other than Outstanding Securities any previously called for redemption) 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 Securities or through the application
of permitted optional sinking fund payments pursuant to the terms of such Securities, as provided for by the terms of such Securities,
or which have otherwise been acquired by the Company; provided that such Securities so delivered or applied as a credit have not
been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the applicable Redemption
Price specified in such Securities for redemption through operation of the sinking fund and the amount of such mandatory sinking
fund payment shall be reduced accordingly.

 

Section
12.03          Redemption of Securities for Sinking Fund.

 

Not less than 60 days
prior to each sinking fund payment date for Securities of any series, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing mandatory sinking fund payment for that series pursuant to the terms of that series,
the portion thereof, if any, which is to be satisfied by payment of cash in the currency or currencies in which the Securities
of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Securities of such series) and the portion
thereof, if any, which is to be satisfied by delivering and crediting Securities of that series pursuant to Section 12.02, and
the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the
Trustee any Securities to be so delivered and credited. If such Officers' 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 30 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 11.03 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 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner stated in Sections 11.06 and 11.07.

 

Article

REPAYMENT AT THE OPTION OF HOLDERS

 

Section
13.01          Applicability of Article.

 

Repayment of Securities
of any series before their Stated Maturity at the option of Holders thereof shall be made in accordance with the terms of such
Securities, if any, and (except as otherwise specified by the terms of such series established pursuant to Section 3.01) in accordance
with this Article.

 

    	61

    	 

    
 

Section
13.02          Repayment of Securities.

 

Securities of any series
subject to repayment in whole or in part at the option of the Holders thereof will, unless otherwise provided in the terms of such
Securities, be repaid at a price equal to the principal amount thereof, together with interest, if any, thereon accrued to the
Repayment Date specified in or pursuant to the terms of such Securities. The Company covenants that at least one Business Day prior
to the Repayment Date it will deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 10.03) an amount of money in the currency or currencies in which the Securities
of such series are payable (except as otherwise specified pursuant to Section 3.01 for the Securities of such series) sufficient
to pay the principal (or, if so provided by the terms of the Securities of any series, a percentage of the principal) of, and (except
if the Repayment Date shall be an Interest Payment Date, unless otherwise specified pursuant to Section 3.01 or in the Securities
of such series) accrued interest on, all the Securities or portions thereof, as the case may be, to be repaid on such date.

 

Section
13.03          Exercise of Option.

 

Securities of any series
subject to repayment at the option of the Holders thereof will contain an "Option to Elect Repayment" form on the reverse
of such Securities. In order for any Security to be repaid at the option of the Holder, the Trustee must receive at the Place of
Payment therefor specified in the terms of such Security (or at such other place or places of which the Company shall from time
to time notify the Holders of such Securities) not earlier than 60 days nor later than 30 days prior to the Repayment Date (1)
the Security so providing for such repayment together with the "Option to Elect Repayment" form on the reverse thereof
duly completed by the Holder (or by the Holder's attorney duly authorized in writing) or (2) a telegram, telex, facsimile transmission
or a letter from a member of a national securities exchange, or the National Association of Securities Dealers, Inc. ("NASD"),
or a commercial bank or trust company in the United States setting forth the name of the Holder of the Security, the principal
amount of the Security, the principal amount of the Security to be repaid, the CUSIP number, if any, or a description of the tenor
and terms of the Security, a statement that the option to elect repayment is being exercised thereby and a guarantee that the Security
to be repaid, together with the duly completed form entitled "Option to Elect Repayment" on the reverse of the Security,
will be received by the Trustee not later than the fifth Business Day after the date of such telegram, telex, facsimile transmission
or letter; provided, however, that such telegram, telex, facsimile transmission or letter shall only be effective if such Security
and form duly completed are received by the Trustee by such fifth Business Day. If less than the entire principal amount of such
Security is to be repaid in accordance with the terms of such Security, the principal amount of such Security to be repaid, in
increments of the minimum denomination for Securities of such series, and the denomination or denominations of the Security or
Securities to be issued to the Holder for the portion of the principal amount of such Security surrendered that is not to be repaid,
must be specified. The principal amount of any Security providing for repayment at the option of the Holder thereof may not be
repaid in part if, following such repayment, the unpaid principal amount of such Security would be less than the minimum authorized
denomination of Securities of the series of which such Security to be repaid is a part. Except as otherwise may be provided by
the terms of any Security providing for repayment at the option of the Holder thereof, exercise of the repayment option by the
Holder shall be irrevocable unless waived by the Company.

 

Section
13.04          When Securities Presented for Repayment Become Due and Payable.

 

If Securities of any
series providing for repayment at the option of the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or the portions thereof, as the case may be, to be
repaid shall become due and payable and shall be paid by the Company on the Repayment Date therein specified, and on and after
such Repayment Date (unless the Company shall default in the payment of such Securities on such Repayment Date) such Securities
shall, if the same were interest-bearing, cease to bear interest and the coupons for such interest appertaining to any Bearer Securities
so to be repaid, except to the extent provided below, shall be void. Upon surrender of any such Security for repayment in accordance
with such provisions, together with all coupons, if any, appertaining thereto maturing after the Repayment Date, the principal
amount of such Security so to be repaid shall be paid by the Company, together with accrued interest, if any, to the Repayment
Date; provided, however, that coupons whose Stated Maturity is on or prior to the Repayment Date shall be payable only at an office
or agency located outside the United States (except as otherwise provided in Section 10.02) and, unless otherwise specified pursuant
to Section 3.01, only upon presentation and surrender of such coupons; and provided further that, in the case of Registered Securities
(except as otherwise specified in or pursuant to this Indenture or the Registered Securities of a series), installments of interest,
if any, whose Stated Maturity is on or prior to the Repayment Date shall be payable (but without interest thereon, unless the Company
shall default in the payment thereof) to the Holders of such Securities, or one or more Predecessor Securities, registered as such
at the close of business on the relevant Record Dates according to their terms and the provisions of Section 3.07.

 

    	62

    	 

    
 

If any Bearer Security
surrendered for repayment shall not be accompanied by all appurtenant coupons maturing after the Repayment Date, such Security
may be paid after deducting from the amount payable therefor as provided in Section 13.02 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
shall 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 as provided in the preceding sentence, such Holder shall be entitled to receive the amount
so deducted; provided, however, that interest represented by coupons shall be payable only at an office or agency located outside
the United States (except as otherwise provided in Section 10.02) and, unless otherwise specified as contemplated by Section 3.01,
only upon presentation and surrender of those coupons.

 

If the principal amount
of any Security surrendered for repayment shall not be so repaid upon surrender thereof, such principal amount (and, to the extent
legally enforceable, the interest, if any, thereon accrued to such Repayment Date) shall, until paid, bear interest from the Repayment
Date at the rate of interest or Yield to Maturity (in the case of Original Issue Discount Securities) borne by such Security on
the Repayment Date.

 

Section
13.05          Securities Repaid in Part.

 

Upon surrender of any
Registered Security which is to be repaid in part only, the Company shall execute and the Trustee shall authenticate and deliver
to the Holder of such Security, without service charge and at the expense of the Company, a new Registered Security or Securities
of the same series, of any authorized denomination specified by the Holder, in an aggregate principal amount equal to and in exchange
for the portion of the principal of such Security so surrendered which is not to be repaid.

Article
XIV.

DEFEASANCE AND COVENANT DEFEASANCE

 

Section
14.01          Applicability of Article; Company's Option to Effect Defeasance
or Covenant Defeasance.

 

If, pursuant to Section
3.01, provision is made for either or both of (a) defeasance of the Securities of or within a series under Section 14.02 or (b)
covenant defeasance of the Securities of or within a series under Section 14.03, then the provisions of such Section or Sections,
as the case may be, together with the other provisions of this Article (with such modifications thereto as may be specified pursuant
to Section 3.01 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 14.02 (if applicable) or Section 14.03 (if applicable) be applied to such Outstanding Securities and any
coupons appertaining thereto upon compliance with the conditions set forth below in this Article.

 

Section
14.02          Defeasance and Discharge.

 

Upon the Company's
exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Company shall
be deemed to have been discharged from its obligations with respect to such Outstanding Securities and any coupons appertaining
thereto on the date the conditions set forth in Section 14.04 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 Section 14.05 and the other Sections of this Indenture referred to in clauses (A) and (B) 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: (A) the rights of Holders of such Outstanding Securities and any coupons appertaining thereto to receive, solely from
the trust fund described in Section 14.04 and as more fully set forth in such Section, payments in respect of the principal of
(and premium, if any) and interest, if any, on such Securities and any coupons appertaining thereto when such payments are due,
(B) the Company's obligations with respect to such Securities under Sections 3.05, 3.06, 10.02 and 10.03 and with respect to the
payment of Additional Amounts, if any, on such Securities as contemplated by Section 10.11, and under or with respect to Section
6.06 hereof, (C) the rights, powers, trusts, duties and immunities of the Trustee hereunder, (D) the rights of Holders to convert
Securities, if any, in accordance with their terms, and (E) this Article. Subject to compliance with this Article Fourteen, the
Company may exercise its option under this Section notwithstanding the prior exercise of its option under Section 14.03 with respect
to such Securities and any coupons appertaining thereto.

 

Section
14.03          Covenant Defeasance.

 

Upon the Company's
exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Company shall
be released from its obligations under Sections 10.05 to 10.10, inclusive, and, if specified pursuant to Section 3.01, its obligations
under any other covenant, with respect to such Outstanding Securities and any coupons appertaining thereto on and after the date
the conditions set forth in Section 14.04 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 Sections 10.05 to 10.10,
inclusive, or such other 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, whether directly or indirectly, by reason of any reference elsewhere herein to any such Section
or such other covenant or by reason of reference in any such Section or such other covenant 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 5.01(4) or 5.01(11)
or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such Securities and any coupons
appertaining thereto shall be unaffected thereby.

 

    	64

    	 

    
 

Section
14.04          Conditions to Defeasance or Covenant Defeasance.

 

The following shall
be the conditions to application of Section 14.02 or Section 14.03 to any Outstanding Securities of or within a series and any

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,
(i) the principal of (and premium, if any) and interest, if any, on such Outstanding Securities and any coupons appertaining thereto
on the Stated Maturity of such principal or installment of principal or interest and (ii) any mandatory sinking fund payments or
analogous payments applicable to such Outstanding Securities and any coupons appertaining thereto on the day 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.
The Trustee shall have no liability for the actions or omissions of any Other Qualifying Trustee.

 

(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 or a Guarantor is a party or by which it is bound.

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

5.01(6) and 5.01(7) are concerned, at any time during the period ending on the 91st day after the date of such deposit (it being
understood that this condition shall not be deemed satisfied until the expiration of such period).

the case of an election under Section 14.02, the Company shall have delivered to the Trustee an Opinion of Counsel stating that

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 Section 14.03, 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 Officers' Certificate and an Opinion of Counsel, each stating that all conditions

related exercise of the Company's option under Section 14.02 or Section 14.03 (as the case may be), registration is not required
under the Investment Company Act of 1940, as amended, by the Company, with respect to the trust funds representing such deposit
or by the Trustee for such trust funds or (ii) all necessary registrations under said Act have been effected.

 

(g)          Notwithstanding
any other provisions of this Section, 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
3.01.

 

Section
14.05          Deposited Money and Government Obligations to Be Held in Trust;
Other Miscellaneous Provisions.

 

Subject to the provisions
of the last paragraph of Section 10.03, all money and Government Obligations (or other property as may be provided pursuant to
Section 3.01) (including the proceeds thereof) deposited with the Trustee (or Other Qualifying Trustee) pursuant to Section 14.04
in respect of any Outstanding Securities of any series and any coupons appertaining thereto shall be held in trust and applied
by the Trustee (or such Other Qualifying Trustee, as applicable), 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 Agent (including the Company
acting as its own Paying Agent) as the Trustee (or such Other Qualifying Trustee, as applicable) may determine, to the Holders
of such Securities and 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 need not be segregated from other funds except to
the extent required by law.

 

    	66

    	 

    
 

Unless otherwise specified
with respect to any Security pursuant to Section 3.01, if, after a deposit referred to in Section 14.04(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 3.01 or the
terms of such Security to receive payment in a currency other than that in which the deposit pursuant to Section 14.04(a) has been
made in respect of such Security, or (b) a Conversion Event occurs in respect of the currency in which the deposit pursuant to
Section 14.04(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 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 the applicable market exchange rate for
such currency in effect on the second Business Day prior to each payment date, except, with respect to a Conversion Event, for
such currency in effect (as nearly as feasible) at the time of the Conversion Event.

 

The Company shall pay
and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the Government Obligations deposited
pursuant to Section 14.04 or the principal and interest received in respect thereof other than any such tax, fee or other charge
which by law is for the account of the Holders of such Outstanding Securities and any coupons appertaining thereto.

 

Anything in this Article
to the contrary notwithstanding, subject to Section 6.06, the Trustee (or such Other Qualifying Trustee, as applicable) 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 Section 14.04 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 Article.

respect to any request, demand, authorization, direction, notice, consent, waiver or other action that this Indenture expressly
provides may be made, given or taken by the Holders of a specified percentage in principal amount of all Outstanding Securities
affected thereby, or of the Holders of such series and one or more additional series:

 

(i)          there
shall be no minimum quorum requirement for such meeting; and

 

(ii)          the
principal amount of the Outstanding Securities of such series that vote in favor of such request, demand, authorization, direction,
notice, consent, waiver or other action shall be taken into account in determining whether such request, demand, authorization,
direction, notice, consent, waiver or other action has been made, given or taken under this Indenture.

 

Section
15.05          Determination of Voting Rights; Conduct and Adjournment of Meetings.

 

(a)          Notwithstanding
any provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of Securities of such series and of the appointment 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.
Except as otherwise permitted or required by any such regulations, the holding of Securities shall be proved in the manner specified
in Section 1.04 and the appointment of any proxy shall be proved in the manner specified in Section 1.04 or by having the signature
of the Person executing the proxy witnessed or guaranteed by any trust company, bank or banker authorized by Section 1.04 to certify
to the holding of Bearer Securities. Such regulations may provide that written instruments appointing proxies, regular on their
face, may be presumed valid and genuine without the proof specified in Section 1.04 or other proof.

 

(b)          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 15.02(b), 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.

 

(c)          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
the Outstanding Securities of such series held or represented by him; provided, however, that no vote shall be cast or counted
at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding.
The chairman of the meeting shall have no right to vote, except as a Holder of a Security of such series or proxy.

 

(d)          Any
meeting of Holders of Securities of any series duly called pursuant to Section 15.02 at which a quorum is present may be adjourned
from time to time by Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented
at the meeting, and the meeting may be held as so adjourned without further notice.

 

Section
15.06          Counting Votes and Recording Action of Meetings.

 

The vote upon 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 serial numbers of
the Outstanding Securities of such series held or represented by them. The permanent chairman of the meeting 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 duplicate of all votes cast at the meeting. A record, at least in
duplicate, 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 fact, setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 15.02 and, if applicable, Section 15.04. Each copy shall be signed and
verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Company
and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting.
Any record so signed and verified shall be conclusive evidence of the matters therein stated.

GUARANTEE OF SECURITIES

 

Section
16.01          Guarantee.

 

(1)          Each
Person designated as a "Guarantor" in the Board Resolution, supplemental indenture or Officers' Certificate establishing
a series of Securities that also establishes itself as a Guarantor of such Securities by Board Resolution or pursuant to authority
granted by one or more Board Resolutions and set forth, or determined in the manner provided, in an Officers' Certificate, or established
in one or more indentures supplemental hereto, with respect to each series of Securities to which this Article Sixteen is made
applicable, irrevocably and unconditionally guarantees (the "Guarantee") to each Holder of a Security of such series
authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and
enforceability of this Indenture, the Securities of such series or the obligations of the Company under this Indenture or the Securities
of such series, that: (i) the principal of and premium, if any, and interest on, or any Additional Amount in respect of, the Securities
of such series will be paid in full when due, whether at the Stated Maturity or Interest Payment Date, by acceleration, call for
redemption, or otherwise; (ii) all other obligations of the Company to the Holders of such series or the Trustee under this Indenture
or the Securities of such series will be promptly paid in full, all in accordance with the terms of this Indenture and the Securities
of such series; and (iii) in case of any extension of time of payment or renewal of any Securities of such series or any of such
other obligations thereunder, they will be paid in full when due in accordance with the terms of the extension or renewal, whether
at the Stated Maturity or Interest Payment Date, by acceleration, call for redemption, or otherwise. Failing payment when due of
any amount so guaranteed for whatever reason, each Guarantor shall be obligated to pay the same before failure so to pay becomes
an Event of Default with respect to Securities of any series. If the Company defaults in the payment of the principal of or premium,
if any, or interest on, or any Additional Amount in respect of, the Securities of a series so guaranteed when and as the same shall
become due, whether at the Stated Maturity or Interest Payment Date, by acceleration, call for redemption, or otherwise, without
the necessity of action by the Trustee or any Holder, each Guarantor with respect to such series shall be required to promptly
make such payment in full. The obligations of all Guarantors under this Article Sixteen shall be joint and several.

 

(2)          Each
Guarantor agrees with respect to Securities of any series that its obligations with regard to this Guarantee shall be as principal
and not merely as surety and shall be full, irrevocable and unconditional, irrespective of the validity, regularity or enforceability
of the Securities of such series or this Indenture, the absence of any action to enforce the same, any delays in obtaining or realizing
upon or failures to obtain or realize upon collateral, the recovery of any judgment against the Company, any action to enforce
the same or any other circumstances that might otherwise constitute a legal or equitable discharge or defense of a surety or a
guarantor. Each Guarantor with respect to Securities of any series hereby waives diligence, presentment, demand of payment, filing
of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against
the Company or right to require the prior disposition of the assets of the Company to meet its obligations, protest, notice and
all demands whatsoever and covenants that this Guarantee will not be discharged except by complete performance of all obligations
contained in the Securities of such series and this Indenture as it relates to such series of Securities.

 

    	70

    	 

    
 

(3)          If
any Holder of Securities of a series or the Trustee is required by any court or otherwise to return to any of the Company or a
Guarantor with respect to Securities of that series, or any Custodian, trustee, or similar official acting in relation to any of
the Company or a Guarantor, any amount paid by any of the Company or a Guarantor to the Trustee or such Holder with respect to
Securities of that series, the Guarantee with respect to Securities of that series, to the extent theretofore discharged, shall
be reinstated in full force and effect. Each Guarantor agrees that it will not be entitled to any right of subrogation in relation
to the Holders of Securities of a series in respect of any obligations guaranteed hereby until payment in full of all obligations
of Securities of such series. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and
the Trustee, on the other hand, (i) the maturity of the obligations guaranteed hereby may be accelerated as provided in Section
5.02 for the purposes of a Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration as
to the Company of the obligations so guaranteed, and (ii) in the event of any declaration of acceleration of those obligations
as provided in Section 5.02, those obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors
with respect to Securities of a series for purposes of the Guarantee.

 

(4)          Each
Guarantor and by its acceptance of a Security issued hereunder each Holder hereby confirms that it is the intention of all such
parties that the Guarantee by each Guarantor set forth in Section 16.01(1) not constitute a fraudulent transfer or conveyance for
purpose of any Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar Federal
or state law. To effectuate the foregoing intention, the Holders and all Guarantors hereby irrevocably agree that the obligations
of each of the Guarantors under the Guarantee set forth in Section 16.01(1) shall be limited to the maximum amount as will, after
giving effect to all other contingent and fixed liabilities of such Guarantor, and after giving effect to any collections from
or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee
or pursuant to the next succeeding sentence, result in the obligations of such Guarantor under such Guarantee not constituting
such a fraudulent transfer or conveyance. Each Guarantor that makes any payment or distribution under Section 16.01(1) shall be
entitled to a contribution from each other Guarantor equal to its Pro Rata Portion of such payment or distribution. For purposes
of the foregoing, the "Pro Rata Portion" of any Guarantor means the percentage of net assets of all Guarantors held by
such Guarantor, determined in accordance with GAAP.

 

(5)          It
is the intention of the parties that the obligations of the Guarantors shall be in, but not in excess of, the maximum amount permitted
by applicable law. Accordingly, if the obligations in respect of the Guarantee would be annulled, avoided or subordinated to the
creditors of any Guarantor by a court of competent jurisdiction in a proceeding actually pending before such court as a result
of a determination both that such Guarantee was made without fair consideration and, immediately after giving effect thereto, such
Guarantor was insolvent or unable to pay its debts as they mature or left with an unreasonably small capital, then the obligations
of such Guarantor under such Guarantee shall be reduced by such court if and to the extent such reduction would result in the avoidance
of such annulment, avoidance or subordination; provided, however, that any reduction pursuant to this paragraph shall be made in
the smallest amount as is strictly necessary to reach such result. For purposes of this paragraph, "fair consideration,"
"insolvency," "unable to pay its debts as they mature," "unreasonably small capital" and the effective
times of reductions, if any, required by this paragraph shall be determined in accordance with applicable law.

 

    	71

    	 

    
 

(6)          If
the obligations of any Guarantor are reduced pursuant to Section 16.01(4) or 1601(5) above, such reduction shall be applied proportionately
with respect to all Securities (of whatever series) guaranteed under Section 16.01, in accordance with the respective outstanding
principal amount of such Securities so guaranteed (or, if any Securities are Original Issue Discount Securities, the accreted value
of such Securities) and being then due upon the acceleration of the payment of such Securities.

 

(7)          A
Guarantor may consolidate with, sell, lease or convey all or substantially all of its assets to, or merge with or into, the Company,
a Subsidiary of the Company or another Guarantor at any time without limitation, provided that, if the successor entity or entity
acquiring the assets is a Subsidiary of the Company or another Guarantor, such entity expressly or by operation of law assumes
all of the obligations of the Guarantor under this Indenture in connection with the transaction. In any such case, the Guarantor
shall be released from all obligations under this Indenture.

 

(8)          In
addition to the transactions permitted by Section 16.01(7), a Guarantor may consolidate with, sell, lease or convey all or substantially
all of its assets to, or merge with or into, any other corporation, provided that, in any such case, the Guarantor shall be the
continuing corporation, or the successor corporation or corporation acquiring the assets shall be a corporation organized and existing
under the laws of the United States or a State thereof and such corporation expressly assumes all of the obligations of the Guarantor
under this Indenture by supplemental indenture complying with Article Nine hereof, satisfactory to the Trustee, executed and delivered
to the Trustee by such corporation. In any such case, the Guarantor shall be released from all obligations under this Indenture.
Any such consolidation, sale, lease, conveyance or merger is also subject to the condition that the Trustee receive an Officers'
Certificate of the Guarantor and an Opinion of Counsel to the effect that the transaction, and the assumption by any successor
corporation or acquiror of assets, complies with the provisions of this Section 16.01(8) and that all conditions precedent herein
provided for relating to such transaction have been complied with.

 

(9)          Upon
a sale, transfer or other disposition of Capital Stock of a Subsidiary Guarantor by the Company to a Person other than the Company,
which disposition (i) is not subject to Section 16.01(7), Section 16.01(8) or Article Eight, (ii) causes such Guarantor to no longer
be a Subsidiary of the Company, (iii) is for consideration at least equal to the fair value of the Capital Stock disposed of (in
the good faith determination of the Board of Directors of the Company) and (iv) is otherwise in compliance with the terms of this
Indenture, such Guarantor shall be released from all obligations under this Indenture. Upon the delivery by the Company to the
Trustee of an Officers' Certificate and, if requested by the Trustee, an Opinion of Counsel to the effect that the transaction
or series of related transactions giving rise to the release of such obligations was made in accordance with the provisions of
this Indenture, the Trustee shall execute any documents reasonably required in order to evidence the release of such Guarantor
from its obligations. Any Guarantor not so released remains liable for the full amount of principal of and premium, if any, and
interest on, and any Additional Amounts with respect to, the Securities as provided in this Article Sixteen.

 

Section
16.02          Future Guarantors.

 

Each Person providing
a guarantee of any Security of a series pursuant to this Indenture shall execute and deliver a supplemental indenture making such
Person a party to this Indenture for the purpose of becoming a Guarantor.

 

    	72

    	 

    
 

Section
16.03          Delivery of Guarantee.

 

The delivery of any
Security of a series by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee
set forth in Section 16.01 on behalf of each Guarantor for that series.

This
Indenture may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same Indenture. The exchange of copies of this Indenture and of signature
pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto
and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or

and delivered upon registration or transfer of, or in exchange for, or in lieu of other Notes pursuant to Section 3.04, Section
3.05, Section 3.06 and Section 9.06 of the Base Indenture and
Section 8.02 and Section 9.04 of this Supplemental Indenture.

 

Section 2.03. Form of Notes. The
Notes shall be substantially in the form set forth in Exhibit A, the terms and provisions of which shall constitute, and are hereby
expressly incorporated in and made a part of the Indenture. To the extent applicable, the Company and the Trustee, by their execution
and delivery of the Indenture, expressly agree to such terms and provisions and to be bound thereby.

 

Any Global Note may be endorsed with or
have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of the Indenture
as may be required by the Note Custodian or the Depositary, or as may be required to comply with any applicable law or any regulation
thereunder or with the rules and regulations of any securities exchange or automated quotation system upon which the Notes may
be listed or traded or designated for issuance or to conform with any usage with respect thereto, or to indicate any special limitations
or restrictions to which any particular Notes are subject.

 

Each Global Note shall represent such principal
amount of the Outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate principal
amount of Outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of Outstanding Notes represented
thereby may from time to time be increased or reduced to reflect redemptions, repurchases, conversions, transfers or exchanges
permitted hereby. Any endorsement of the Global Note to reflect the amount of any increase or decrease in the amount of Outstanding
Notes represented thereby shall be made on the Schedule of Exchanges of Notes to such Global Note by the Trustee or the Note Custodian,
at the direction of the Trustee, in such manner and upon instructions given by the Holder of such Notes in accordance with the
Indenture. Payment of principal (including the Fundamental Change Repurchase Price, if applicable) of, the Redemption Price of
(if applicable), accrued and unpaid interest on, and the consideration due upon conversion of, the Global Note shall be made to
the Holder of such Note (or, in the case of consideration due upon conversion, such Holder or its designee, as the case may be)
on the date of payment, unless a record date or other means of determining Holders of the Notes eligible to receive payment is
provided for herein.

Section 2.04. Depositary.

 

(a)           
So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, all
Notes shall be represented by one or more global Securities to which the provisions of Section 2.03 of the Base Indenture apply
(each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer
and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note, shall be effected
through the Depositary (but not the Trustee or the Note Custodian) in accordance with the Indenture (including the restrictions
on transfer set forth herein) and the Applicable Procedures of the Depositary therefor.

 

(b)           
The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints DTC to act
as Depositary with respect to each Global Note. Initially, each Global Note shall be issued to the Depositary, registered in the
name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co.

 

(c)           
The fourth sentence of the fifth paragraph of Section 3.05 of the Base Indenture is hereby amended and restated in full,
with respect to the Notes, to read as follows:

 

“Definitive Securities shall
be issued and delivered by the Company (i) to each person that DTC identifies as a beneficial owner of the related Securities only
if (a) DTC has notified the Company that it is unwilling or unable to continue as depositary for the global Securities of the relevant
series and a successor depositary is not appointed within 90 calendar days or (b) DTC ceases to be registered as a clearing agency
under the Exchange Act and a successor depositary is not appointed within 90 calendar days or (ii) if an Event of Default with
respect to the Securities of any series has occurred and is continuing, to each beneficial owner who requests that its beneficial
interests in the Securities be exchanged for Securities in definitive form.”

 

(d)           
Notwithstanding anything to the contrary in the Indenture (including, without limitation, Sections 1.01, 2.03 and 3.08
of the Base Indenture) or the Notes, following the occurrence and during the continuance of an Event of Default, any beneficial
owner of a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any
other action of the Depositary or any other Person, such beneficial owner’s right to exchange its beneficial interest in
such Global Note for a Physical Note in accordance with Section 3.05 of the Base Indenture.

 

    	12

    	 

    
 

(e)           
At such time as all interests in a Global Note have been converted, canceled, repurchased or transferred, such Global Note
shall be, upon receipt thereof, canceled by the Trustee in accordance with Applicable Procedures. At any time prior to such cancellation,
if any interest in a Global Note is exchanged for Physical Notes, converted, canceled, repurchased or transferred to a transferee
who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal
amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary
and the Note Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on the Schedule
of Exchanges of Notes to such Global Note, by the Trustee or the Note Custodian, at the direction of the Trustee, to reflect such
reduction or increase.

 

Section 2.05. Cancellation of Surrendered
Notes. The Company shall cause all Notes surrendered for payment, repurchase (including pursuant to Section 2.07, but excluding
Notes repurchased pursuant to cash-settled swaps or other derivatives), redemption, registration of transfer or exchange or conversion,
if surrendered to any Person other than the Trustee (including any of the Company’s Agents, Subsidiaries or Affiliates),
to be delivered to the Trustee for cancellation pursuant to Section 3.09 of the Base Indenture. All Notes delivered to the Trustee
shall be cancelled promptly by the Trustee. No Notes shall be authenticated in exchange for any Notes cancelled hereunder or under
the Base Indenture. For purposes of the Notes, the third to last sentence in Section 3.09 of the Base Indenture shall be deemed
to be deleted.

 

Section 2.06. Notice of Defaults. The
Company shall deliver to the Trustee, at its Corporate Trust Office, in accordance with Section 1.05 of the Base Indenture, within
30 calendar days after the occurrence thereof, an Officers’ Certificate containing notice of any events that would constitute
Defaults, the status thereof and what action the Company is taking or proposes to take in respect thereof, which notice shall make
express reference to the Company, the Indenture and the Notes.

 

Section 2.07. Additional Notes; Repurchases.
The Company may, without the consent of the Holders of the Notes and notwithstanding Section 2.01, reopen this Supplemental Indenture
and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder in an unlimited aggregate principal
amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal
income tax purposes, such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes,
the Company shall deliver to the Trustee a Company Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’
Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 1.02 of the Base Indenture,
as the Trustee shall reasonably request. In addition, the Company may, to the extent permitted by law, and directly or indirectly
(regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by
the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements,
including by cash-settled swaps or other derivatives.

payable under this Supplemental Indenture by the Company; and (b) the Company has delivered to the Trustee an Officers’ Certificate
and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge

4.02 shall supersede Section 10.09 of the Base Indenture and all references in the Base Indenture to Section 10.09 thereof shall

that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to

set forth in this Article 5 shall, with respect to the Notes, supersede in their entirety Article V of the Base Indenture, and
all references in the Base Indenture to Article V thereof and Events of Default provisions therein, as the case may be, shall,

at least 25% in principal amount of the Notes then Outstanding to the Company and the Trustee, has been received to comply with
any of the Company’s other agreements contained in the Notes or this Indenture;

 

(h)           
default by the Company or any of its Subsidiaries that do not constitute Immaterial Foreign Subsidiaries with respect to
any mortgage, agreement or other instrument under which there may be outstanding, or by which there may be secured or evidenced,

and/or any such Subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness

due and payable at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise;

 

(i)           
a final judgment for the payment of $15 million (or its foreign currency equivalent) or more (excluding any amounts covered
by insurance) rendered against the Company or any of the its Subsidiaries that do not constitute Immaterial Foreign Subsidiaries,
which judgment is not discharged or stayed within 60 calendar days after (i) the date on which the right to appeal thereof has
expired if no such appeal has commenced, or (ii) the date on which all rights to appeal have been extinguished;

 

(j)           
the Company or any Significant Subsidiary shall commence a voluntary case or other proceeding seeking liquidation, reorganization
or other relief with respect to the Company or any such Significant Subsidiary or its debts under any bankruptcy, insolvency or
other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, Custodian or other
similar official of the Company or any such Significant Subsidiary or any substantial part of its property, or shall consent to
any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding
commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts
as they become due; or

 

    	16

    	 

    
 

(k)           
an involuntary case or other proceeding shall be commenced against the Company or any Significant Subsidiary seeking liquidation,
reorganization or other relief with respect to the Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency
or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, Custodian or other
similar official of the Company or such Significant Subsidiary or any substantial part of its property, and such involuntary case
or other proceeding shall remain undismissed and unstayed for a period of 30 consecutive calendar days.

 

Section 5.03. Acceleration of Maturity.
If an Event of Default (other than an Event of Default specified in Section 5.02(j) or Section 5.02(k)) shall occur and be
continuing, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then Outstanding, by notice
in writing to the Company (and to the Trustee if given by Holders of the Notes), may declare 100% of the principal of and accrued
and unpaid interest, if any, on all the Notes to be immediately due and payable, and upon any such declaration such principal and
accrued and unpaid interest, if any, shall be due and payable immediately. If an Event of Default specified in Section 5.02(j)
or Section 5.02(k) occurs, 100% of the principal of and accrued and unpaid interest on the Notes shall automatically become due
and payable without necessity of further action.

 

Section 5.04. Additional Interest. Notwithstanding
Section 5.03, to the extent elected by the Company, the sole remedy for an Event of Default relating to (i) the failure by the
Company to file with the Trustee pursuant to Section 314(a)(1) of the Trust Indenture Act any documents or reports that the Company
is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act or (ii) the failure to comply with
the reporting obligations under Section 4.02, shall for the first 120 calendar days after the occurrence of such an Event of Default
consist exclusively of the right to receive additional interest (“Additional Interest”) on the Notes at a rate
equal to (x) 0.25% per annum of the principal amount of the Notes Outstanding for each day during the first 60 calendar
days of such 120 calendar day period on which such Event of Default is continuing and (y) 0.50% per annum of the principal
amount of the Notes Outstanding for the remaining 60 calendar days of such 120 calendar day period on which such Event of Default
is continuing.

 

If the Company so elects to pay Additional
Interest, any such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable
on the Notes. On the 121st calendar day after such Event of Default (if the Event of Default relating to the reporting
obligations is not cured or waived prior to such 121st  calendar day), the Notes shall be subject to acceleration under
Section 5.03. The provisions of this Section 5.04 shall not affect the rights of Holders of the Notes in the event of the occurrence
of any other Event of Default. In the event the Company does not elect to pay the Additional Interest following an Event of Default
in accordance with this Section 5.04 or the Company elected to make such payment but does not pay the Additional Interest when
due, the Notes shall be immediately subject to acceleration under Section 5.03.

 

    	17

    	 

    
  

In order to elect to pay the Additional
Interest as the sole remedy during the first 120 calendar days after the occurrence of an Event of Default relating to the failure
to comply with its reporting obligations under Section 314(a)(1) of the TIA or under Section 4.02, in accordance with this Section
5.04, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning
of such 120-day period. Upon the Company’s failure to timely give such notice, the Notes shall be immediately subject to
acceleration under Section 5.03. Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office
such a notice, the Trustee may assume without inquiry that no such Additional Interest is payable.

 

Section 5.05. Rescission and Annulment.
Holders of a majority in principal amount of the Outstanding Notes, by written notice to the Company and to the Trustee, may
rescind any acceleration under Section 5.03 with respect to the Notes and its consequences if:

 

(a)          such
rescission would not conflict with any judgment or decree of a court of competent jurisdiction;

 

(b)          all
existing Events of Default, other than the nonpayment of the principal of and interest on the Notes that have become due solely
by such declaration of acceleration, have been cured or waived; and

 

(c)          all
amounts owing to the Trustee hereunder have been paid.

 

No such rescission and annulment shall extend
to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon.

 

In case the Trustee shall have proceeded
to enforce any right under the Indenture and such proceedings shall have been discontinued or abandoned because of such waiver
or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such
case the Company, the Holders of the Notes, and the Trustee shall be restored respectively to their several positions and rights
hereunder, and all rights, remedies and powers of the Company, the Holders of the Notes, and the Trustee shall continue as though
no such proceeding had been taken.

 

Section
5.06. Payments of Notes on Default; Suit Therefor. Payments of the Redemption Price, the Fundamental Change Repurchase
Price, principal and interest that are not made when due shall accrue interest per annum at the then-applicable interest
rate plus one percent from the required payment date. For the avoidance of doubt, any such interest on overdue interest
shall be included, to the extent lawful, in the term “Defaulted Interest” for purposes of the Base Indenture.

 

The Company covenants that in the
case of an Event of Default pursuant to Section 5.02 (a)or Section
5.02(b), upon demand of the Trustee, the Company shall pay to the Trustee, for the benefit of the Holders of the
Notes, (i) the whole amount that then shall be due and payable on all such Notes for principal, including the Fundamental
Change Repurchase Price, if applicable, the Redemption Price, if applicable, or interest, as the case may be, with interest
upon the overdue principal and (to the extent that payment of such interest is enforceable under applicable law) upon the
overdue installments of accrued and unpaid interest determined in accordance with the first paragraph of this Section
5.06 and (ii) any amounts due the Trustee under Section 6.06 of the Base Indenture.

 

    	18

    	 

    
 

In case the Company shall fail forthwith
to pay such amounts, upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered
to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute
any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Company
or any other obligor on the Notes and collect in the manner provided by law out of the property of the Company or any other obligor
on the Notes wherever situated the monies adjudged or decreed to be payable.

 

In case there shall be pending
proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under any
Bankruptcy Law, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, Custodian or similar official shall have been appointed for or taken possession of the Company or such other
obligor, the property of the Company or such other obligor, or in the case of any other judicial proceedings relative to the
Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the
Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of
this Section 5.06, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a
claim or claims for the whole amount of principal (including the Fundamental Change Repurchase Price, if applicable), the
Redemption Price, if applicable, and accrued and unpaid interest in respect of the Notes, and, in case of any judicial
proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee and of the Holders of the Notes allowed in such judicial proceedings relative to the Company or any
other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other
property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due the
Trustee under Section 6.06 of the Base Indenture, and to take any other action with respect to such claims,
including participating as a member of any official committee of creditors, as it reasonably deems necessary or advisable,
unless prohibited by law or applicable regulations, and any receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, Custodian or similar official is hereby authorized by each of the Holders of the Notes 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 the
Notes, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including
counsel fees and expenses incurred by it up to the date of such distribution. To the extent that such payment of reasonable
compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason,
payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies,
securities and other property which the Holders of the Notes may be entitled to receive in such proceedings, whether in
liquidation or under any plan of reorganization or arrangement or otherwise.

 

    	19

    	 

    
 

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

 

All rights of action and of asserting claims
under the Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the
production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment
of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable
benefit of the Holders of the Notes.

 

In any proceedings brought by the Trustee
(and in any proceedings involving the interpretation of any provision of the Indenture to which the Trustee shall be a party),
the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes
parties to any such proceedings.

 

In case the Trustee shall have proceeded
to enforce any right under the Indenture and such proceedings shall have been discontinued or abandoned because of such waiver
or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such
case the Company, the Holders of the Notes, and the Trustee shall, subject to any determination in such proceeding, be restored
respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders of
the Notes, and the Trustee shall continue as though no such proceeding had been instituted.

 

Section 5.07. Application of
Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 5 with respect to the Notes and
any other monies or property distributable in respect of the Company’s obligations under this Indenture following an
Event of Default specified in Section 5.02(j) or Section 5.02(k) with respect to the Company shall be applied in the order
following, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several
Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid (or in accordance
with Applicable Procedures, with respect to Global Notes):

 

First, to the payment of all amounts
due the Trustee and any predecessor Trustee under Section 6.06 of the
Base Indenture;

 

Second, in case the principal of
the Outstanding Notes shall not have become due and be unpaid, to the payment of accrued and unpaid interest on, and any cash due
upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion,
as the case may be, with interest (to the extent that such interest has been collected by the Trustee) upon such overdue payments
at the rate borne by the Notes at such time plus one percent, such payments to be made ratably to the Persons entitled thereto;

 

    	20

    	 

    
 

Third, in case the principal of the
Outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount (including
the Redemption Price or Fundamental Change Repurchase Price and any cash due upon conversion, if applicable) then owing and unpaid
upon the Notes for principal and interest, if any, and any cash due upon conversion other amounts then payable on the Notes, with
interest on the overdue principal and, to the extent that such interest has been collected by the Trustee, upon overdue installments
of accrued and unpaid interest and any such cash due upon conversion or other amounts at the rate borne by the Notes at such time
plus one percent, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon
the Notes, then to the payment of such principal and such interest without preference or priority of principal over interest, or
of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other
Note, ratably to the aggregate of such principal and such accrued and unpaid interest; and

 

Fourth, to the payment of the remainder,
if any, to the Company.

 

Section 5.08. Proceedings by Holders
of the Notes. No Holder of any Note shall have any right by virtue of or by availing of any provision of the Indenture to institute
any suit, action or proceeding in equity or at law upon or under or with respect to the Indenture, or for the appointment of a
receiver, trustee, liquidator, Custodian or other similar official, or for any other remedy hereunder, except to enforce the right
to receive payment of principal or interest on the Notes when due or the right to receive payment or delivery of the consideration
due upon conversion of the Notes, unless:

 

(a)          such
Holder shall have given to the Trustee written notice of an Event of Default and of the continuance thereof;

 

(b)          the
Holders of at least 25% in principal amount of the Notes then Outstanding shall have made written request upon the Trustee to institute
such action, suit or proceeding;

 

(c)          such
Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability
or expense;

 

(d)          the
Trustee shall not have complied with such request within 60 calendar days after the receipt of the request and the offer of security
or indemnity; and

 

(e)          the
Holders of a majority in principal amount of the Outstanding Notes have not given the Trustee a direction that, in the opinion
of the Trustee, is inconsistent with such request within such 60-day period pursuant to Section 5.11;

 

it being understood and intended, and being
expressly covenanted by the taker and Holder of every Note with every other taker and Holder of the Notes and the Trustee that
no one or more Holders of the Notes shall have any right in any manner whatever by virtue of or by availing of any provision of
the Indenture to affect, disturb or prejudice the rights of any other Holder of the Notes, or to obtain or seek to obtain priority
over or preference to any other such Holder of the Notes, or to enforce any right under the Indenture, except in the manner herein
provided and for the equal, ratable and common benefit of all Holders of the Notes (except as otherwise provided herein). For
the protection and enforcement of this Section 5.08, each and every Holder of the Notes and the Trustee shall be entitled to such
relief as can be given either at law or in equity.

 

    	21

    	 

    
 

Notwithstanding any other provision of the
Indenture and any provision of the Notes, the right of the Holder of any Note to receive payment or delivery, as the case may be,
of (w) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (x) accrued and unpaid interest, if
any, on, (y) if applicable, the Redemption Price of and (z) the consideration due upon conversion of, such Note, on or after
the respective due dates expressed or provided for in such Note or in the Indenture, or to institute suit for the enforcement of
any such payment or delivery, as the case may be, on or after such respective dates against the Company shall not be impaired or
affected without the consent of such Holder.

 

Anything contained in this Indenture or
the Notes to the contrary notwithstanding, the Holder of any Note, without the consent of either the Trustee or the Holder of any
other Note, in its own behalf and for its own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce,
its rights of conversion as provided herein.

 

Section 5.09. Proceedings by Trustee.
In case of an Event of Default, the Trustee may, in its discretion, proceed to protect and enforce the rights vested in it by the
Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in
equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or
agreement contained in the Indenture or in aid of the exercise of any power granted in the Indenture, or to enforce any other legal
or equitable right vested in the Trustee by the Indenture or by law.

 

Section 5.10. Remedies Cumulative
and Continuing. Except as provided in the last paragraph of Section 3.06 of the Base Indenture, all powers and remedies
given by this Article 5 to the Trustee or to the Holders of the Notes shall, to the extent permitted by law, be deemed
cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of
the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements
contained in the Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to exercise any
right or power accruing upon any Default or Event of Default occurring and continuing as aforesaid shall impair any such
right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein;
and, subject to the provisions of Section 5.08, every power and remedy given by this Article 5 or by law to the Trustee or to
the Holders of the Notes may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by
the Holders of the Notes.

  

Section 5.11. Direction of Proceedings
and Waiver of Defaults by Majority of Holders of the Notes. The Holders of not less than a majority in aggregate principal
amount of the Notes at the time Outstanding shall have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee with respect to Notes; provided,
however, that Article 1 such direction shall not be in conflict with any rule of law or with the Indenture, and Article
2 the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee
may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder of the Notes or
that would involve the Trustee in personal liability. The Holders of a majority in aggregate principal amount of the Notes at
the time Outstanding may, on behalf of the Holders of all of the Notes, waive any past Default or Event of Default hereunder and
its consequences except (i) a default in the payment of principal of, or interest on, any Note when due; (ii) a failure by the
Company to convert any Notes in accordance with the provisions of the Indenture; (iii) a failure by the Company to pay the Redemption
Price on the Redemption Date in connection with a redemption by the Company or the Fundamental Change Repurchase Price on the
Fundamental Change Repurchase Date in connection with a repurchase by the Company in connection with a Fundamental Change, in
each case, in accordance with the Indenture; or (iv) a failure the Company to comply with any of the provisions of the Indenture
the non-compliance with which would require the consent of the Holder of each Outstanding Note affected thereby. Upon any such
waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder;
but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.
Whenever any Default or Event of Default hereunder shall have been waived as permitted by this
Section 5.11, said Default or Event of Default shall for all purposes of the Notes and the Indenture be deemed to have
been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or
impair any right consequent thereon.

 

    	22

    	 

    
 

Section 5.12. Notice of Defaults.
If a Default has occurred and is continuing and is known to the Trustee, the Trustee shall mail to each Holder of the Notes, at
the address of such Holder included in the Security Register, notice of such Default within 90 calendar days after it occurs; provided
that, except in the case of a Default in the payment of the principal of, or interest on, any of the Notes or a Default in the
payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and
so long as a committee of Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in
the interests of the Holders of the Notes.

 

Section 6.01 of the Base Indenture shall
not apply to the Notes. Instead this Section 5.12 shall, with respect to the Notes, supersede in its entirety Section 6.01 of
the Base Indenture, and all references in the Base Indenture to Section 6.01 thereof and the notice provisions therein, as the
case may be, shall, with respect to the Notes, be deemed to be references to this Section 5.12 and the notice provisions set forth
in this Section 5.12, respectively.

 

Section 5.13. Undertaking to Pay Costs.
All parties to the Indenture agree, and each Holder of any Note by its 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 the 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 an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable
attorneys’ fees and expenses, 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; provided that the provisions of this Section 5.13 (to the extent permitted
by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder of the Notes, or group of
Holders of the Notes, holding in the aggregate more than 10% in principal amount of the Notes at the time Outstanding, or to any
suit instituted by any Holder of the Notes for the enforcement of the payment of the principal (including the Fundamental Change
Repurchase Price, if applicable) of, the Redemption Price, if applicable, of, or accrued and unpaid interest, if any, on, any
Note on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert
any Note in accordance with the provisions of Article 8.

to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or any supplemental indenture or of modifying in
any manner the rights of the Holders; provided that, in addition to the restrictions set forth in the first sentence of

to provide that certain other provisions of the Indenture may not be modified or waived without the consent of the Holder of each
Outstanding Note affected thereby.

 

The portion of Section 9.02 of the Base
Indenture preceding clause (1) thereof is hereby amended and restated, with respect to the Notes, to read as follows:

 

“Notwithstanding anything

the relevant supplemental indenture.

 

Section 6.04. Evidence of Compliance
of Supplemental Indenture to be Furnished to Trustee. For the avoidance of doubt, Section 9.03 of the Base Indenture shall

Section 7.01. Applicability of Article
VIII of the Base Indenture. Article VIII of the Base Indenture shall not apply to the Notes. The provisions set forth in this
Article 7 shall, with respect to the Notes, supersede in their entirety Article VIII of the Base Indenture, and all references
in the Base Indenture to Article VIII thereof shall, with respect to the Notes, be deemed to be references to this Article 7.

 

Section 7.02. Company May Consolidate,
etc. on Certain Terms. Subject to the provisions of Section 7.03, the Company shall not consolidate with, merge with or into,
or sell, convey, transfer or lease all or substantially all of its assets to, another Person (any such transaction, a “Consolidation
Transaction”), unless:

 

    	25

    	 

    
 

(a)          the
resulting, surviving, or transferee person (the “Successor Company”), if not the Company, shall be a corporation
organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and the Successor
Company (if not the Company) shall expressly assume, by supplemental indenture all of the obligations of the Company under the
Notes and the Indenture; and

 

(b)          immediately
after giving effect to the transaction, no Default or Event of Default shall have occurred and be continuing.

 

For purposes of this Section 7.02, the sale,
conveyance, transfer or lease of all or substantially all of the assets of one or more Subsidiaries of the Company to another Person,
which assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the assets of the
Company on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the
assets of the Company to another Person.

 

Section 7.03. Successor Company to be
Substituted. Upon any such consolidation, merger or sale, conveyance, transfer or lease, the Successor Company (if not the
Company) shall succeed to, and may exercise every right and power of, the Company under the Indenture with the same effect as if
such successor had been named as the Company herein; and thereafter the Company shall be discharged from its obligations under
the Notes and this Indenture, except in the case of any such lease.

 

In case of any such consolidation, merger,
sale, conveyance, transfer or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter
to be issued as may be appropriate.

 

Section 7.04. Opinion of Counsel to be
Given to Trustee. No consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee shall
receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale,

such supplemental indenture, complies with the provisions of this Article 7.

Conversion of Notes

 

Section 8.01. Conversion Privilege.
Article 10 Subject to and upon compliance with the provisions of this Article 8, each Holder of the Notes shall have the right,
at such Holder’s option, to irrevocably convert all or any portion (if the portion to be converted is $1,000 principal amount
or an integral multiple thereof) of such Note (i) subject to satisfaction of the conditions described in Section 8.01(b), at any
time prior to the close of business on the Business Day immediately preceding November 1, 2017 under the circumstances and during
the periods set forth in Section 8.01(b), and (ii) irrespective of the conditions described in Section 8.01(b), on or after November
1, 2017 until the close of business on the second Business Day immediately preceding the Maturity Date, in each case, at an initial
conversion rate of 85.4372 shares of Common Stock (subject to adjustment as provided in Section
8.04, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to the settlement provisions
of Section 8.02, the “Conversion Obligation”).

 

    	26

    	 

    
 

(b)          Article
11 Prior to the close of business on the Business Day immediately preceding November 1, 2017, the Notes may be surrendered for
conversion during the five Business Day period immediately after any five consecutive Trading Day period (the “Measurement
Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder
of the Notes in accordance with this subsection (b)(i) and the definition of “Trading Price” in Section 1.01, for each
Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and
the Conversion Rate on each such Trading Day (the “Trading Price Condition”).

 

(A)          The
Trading Prices shall be determined by the Company based on bids, if any, received by the Bid Solicitation Agent pursuant to this
subsection (b)(i) and the definition of Trading Price set forth in this Supplemental Indenture.

 

(B)          The
Bid Solicitation Agent shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes or whether
the Trading Price Condition has been met. The Bid Solicitation Agent shall have no obligation to solicit bids from nationally recognized
securities dealers the Company selects unless the Company has requested such solicitation in writing providing the name and contact
information for the nationally recognized securities dealers the Company has chosen and the determination dates for which such
market bid quotations are to be solicited, and the Company shall have no obligation to make such request or determine the Trading
Price unless a Holder of the Notes provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount
of Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate, at
which time the Company shall instruct the Bid Solicitation Agent to solicit bids pursuant to this subsection (b)(i) and the definition
of Trading Price, and based upon such bids the Company shall determine the Trading Price per $1,000 principal amount of Notes beginning
on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater
than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate.

 

(C)          If
(x) the Company does not, when it is required to, instruct the Bid Solicitation Agent to solicit bids as described above,
(y) the Company gives such instruction to the Bid Solicitation Agent to solicit bids and the Bid Solicitation Agent fails
to obtain such bids or (z) the Bid Solicitation Agent obtains such bids and the Company fails to determine the Trading Price
based upon such bids, then, in each case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than
98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such failure.

 

    	27

    	 

    
 

(D)          If
the Trading Price Condition has been met on any Trading Day, the Company shall provide notice thereof to the Holders of the Notes,
the Trustee and the Conversion Agent (if other than the Trustee) in writing on such Trading Day, subject to Section 1.05 and the
last paragraph of Section 1.06 of the Base Indenture. If, at any time after the Trading Price Condition has been met, the Trading
Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the
Common Stock and the Conversion Rate for such Trading Day, the Company shall promptly provide notice thereof to the Holders of
the Notes, the Trustee and the Conversion Agent (if other than the Trustee) in writing, subject to Section 1.05 and the last paragraph
of Section 1.06 of the Base Indenture.

 

(ii)          If,
prior to the close of business on the Business Day immediately preceding November 1, 2017, the Company elects to:

 

(A)          issue
to all or substantially all holders of its Common Stock any rights, options or warrants entitling them, for a period of not more
than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of Common Stock at a price
per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day
period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or

 

(B)          distribute
to all or substantially all holders of its Common Stock the Company’s assets, debt securities or rights to purchase securities
of the Company, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of
the Last Reported Sale Price of the shares of Common Stock on the Trading Day preceding the date of announcement for such distribution,

 

then, in either case, the Company shall notify all Holders of
the Notes, the Trustee and the Conversion Agent (if other than the Trustee) at least 30 Scheduled Trading Days prior to the Ex-Dividend
Date for such issuance or distribution. Once the Company has given such notice, Holders may surrender their Notes for conversion
at any time until the earlier of (1) the close of business on the Business Day immediately preceding the Ex-Dividend Date for such
issuance or distribution and (2) the Company’s announcement that such issuance or distribution will not take place, even
if the Notes are not otherwise convertible at such time.

 

(iii)          If
a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the close of business
on the Business Day immediately preceding November 1, 2017, regardless of whether a Holder of the Notes has the right to require
the Company to repurchase the Notes pursuant to Section 9.02, or if the Company is a party to a consolidation, merger, binding
share exchange or similar transaction, or transfer or lease of all or substantially all of its assets, pursuant to which the Common
Stock would be converted into cash, securities or other assets, the Notes may be surrendered for conversion at any time from or
after the date that is 30 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the
Business Day after the Company gives notice of such transaction) until 35 Trading Days after the actual effective date of such
transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date.
The Company shall notify Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) (i) as promptly
as practicable following the date the Company publicly announces such transaction but in no event less than 30 Scheduled Trading
Days prior to the anticipated effective date of such transaction or (ii) if the Company does not have knowledge of such transaction
at least 30 Scheduled Trading Days prior to the anticipated effective date of such transaction, within three Business Days of the
date upon which the Company receives notice, or otherwise becomes aware, of such transaction but in no event later than the actual
effective date of such transaction.

 

    	28

    	 

    
 

(iv)          Prior
to the close of business on the Business Day immediately preceding November 1, 2017, a Holder may surrender all or a portion of
its Notes (that is $1,000 principal amount or an integral multiple thereof) for conversion during any calendar quarter commencing
after the calendar quarter ending on June 30, 2012 (and only during such calendar quarter), if the Last Reported Sale Price of
the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending
on the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the Conversion Price
on each applicable Trading Day. The Company shall determine at the beginning of each calendar quarter commencing after June 30,
2012 whether the Notes may be surrendered for conversion in accordance with this clause (iv) and shall notify the Holders of the
Notes, the Trustee and the Conversion Agent if the Notes become convertible in accordance with this clause (iv).

 

(v)          If
the Company calls the Notes for redemption pursuant to Article 10, Holders may convert their Notes at any time prior to the close
of business on the Business Day immediately preceding the Redemption Date, even if the Notes are not otherwise convertible at such
time. After that time, Holders will no longer have the right to convert their Notes on account of the Company’s delivery
of the relevant Redemption Notice, unless the Company defaults in the payment of the Redemption Price, in which case a Holder of
the Notes may convert its Notes until the Redemption Price has been paid or duly provided for.

 

Section 8.02. Conversion Procedure; Settlement
Upon Conversion.

 

(a)          Subject
to this Section 8.02, Section 8.03(b) and Section 8.07(a), upon conversion of any Note, the Company shall pay or deliver, as the
case may be, to the converting Holder of the Notes, in respect of each $1,000 principal amount of Notes being converted, cash (“Cash
Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock
in accordance with subsection (i) of this Section 8.02 (“Physical Settlement”) or a combination of cash and
shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with subsection
(i) of this Section 8.02 (“Combination Settlement”), at its election, as set forth in this Section 8.02.

 

    	29

    	 

    
 

(i)          All
conversions occurring on or after November 1, 2017 and all conversions occurring after the Company’s issuance of a Redemption
Notice with respect to the Notes and prior to the related Redemption Date shall be settled using the same Settlement Method.

 

(ii)          Except
for any conversions that occur after the Company’s issuance of a Redemption Notice with respect to the Notes but prior to
the related Redemption Date and any conversions occurring on or after November 1, 2017, the Company shall use the same Settlement
Method for all conversions occurring on the same Conversion Date, but the Company shall not have any obligation to use the same
Settlement Method with respect to conversions that occur on different Conversion Dates.

 

(iii)          Subject
to the two immediately succeeding sentences, if, in respect of any Conversion Date, the Company elects a Settlement Method in respect
of such Conversion Date, the Company, through the Trustee, shall deliver the relevant Settlement Notice to converting Holders of
the Notes no later than the close of business on the Trading Day immediately following the relevant Conversion Date. In the case
of any conversions occurring on or after the date of issuance of a Redemption Notice with respect to the Notes and prior to the
related Redemption Date, if the Company elects a Settlement Method, the Company shall notify Holders of the Notes of the relevant
Settlement Method in such Redemption Notice. In the case of any conversions on or after November 1, 2017, if the Company elects
a Settlement Method, the Company, through the Trustee, shall deliver a Settlement Notice to all Holders of the Notes no later than
November 1, 2017. If the Company does not elect a Settlement Method prior to the relevant deadline set forth in the three immediately
preceding sentences, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company
shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount
per $1,000 principal amount of Notes shall be equal to $1,000. The Settlement Notice shall specify the relevant Settlement Method
and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount.
If the Company elects Combination Settlement, but does not timely notify converting Holders of the Specified Dollar Amount, such
Specified Dollar Amount shall be deemed to be $1,000.

 

(iv)          The
cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any conversion of Notes (the “Settlement
Amount”) shall be computed by the Company as follows:

 

(A)          if
the Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall
deliver to the converting Holder a number of shares of Common Stock equal to the product of Article 12 the aggregate principal
amount of Notes to be converted, divided by $1,000, and Article 13 the Conversion Rate in effect on the Conversion
Date;

 

    	30

    	 

    
 

(B)          if
the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay
to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum
of the Daily Conversion Values for each of the 20 consecutive Trading Days during the related Observation Period; and

 

(C)          if
the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination
Settlement, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal
amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 20 consecutive
Trading Days during the relevant Observation Period.

 

(v)          The
Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly
following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily
Conversion Values, as the case may be, and the amount of cash payable in lieu of any fractional share, the Company shall notify
the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily Conversion Values,
as the case may be, and the amount of cash payable in lieu of fractional shares of Common Stock. The Trustee and the Conversion
Agent (if other than the Trustee) shall have no responsibility for any such determination.

 

(b)          Subject
to Section 8.02(e), before any Holder of a Note shall be entitled
to convert a Note as set forth above, such Holder shall Article 14 in the case of a Global Note, comply with the procedures of
the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to
which such Holder is not entitled as set forth in Section 8.02(g) and Article 15 in the case of a Physical Note (1) complete, manually
sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile
thereof) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal
amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates
for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such
Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office
of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds
equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 8.02(g).
The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 8 on the
Conversion Date for such conversion. No Holder may surrender Notes for conversion if such Holder has also delivered a Fundamental
Change Repurchase Notice to the Company in respect of such Notes and not validly withdrawn such Fundamental Change Repurchase Notice
in accordance with Section 9.03.

 

If more than one Note shall be surrendered
for conversion at one time by the same Holder of the Notes, the Conversion Obligation with respect to such Notes shall be computed
on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so
surrendered.

 

    	31

    	 

    
 

(c)          A
Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”)
that the Holder of the Notes has complied with the requirements set forth in subsection (b) above. The Company shall pay or deliver,
as the case may be, the consideration due (including any cash in lieu of fractional shares) in respect of the Conversion Obligation
on the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on
the third Business Day immediately following the last Trading Day of the relevant Observation Period, in the case of any other
Settlement Method (subject to the provisions of Section 8.03(b) and Section 8.07(a)). If any shares of Common Stock are due to
converting Holders of the Notes, the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such
Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number
of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation.

 

(d)          In
case any Note shall be surrendered for partial conversion, in $1,000 principal amount or an integral multiple thereof, the Company
shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered
a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered
Note, without payment of any service charge by the converting Holder of the Notes but, if required by the Company or Trustee, with
payment of a sum sufficient to cover any transfer tax or similar governmental charge required by law or that may be imposed in
connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the
name of the Holder of the old Notes surrendered for such conversion.

 

(e)          If
a Holder of the Notes submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer
tax due on the issuance of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares
of Common Stock to be issued in a name other than such Holder’s name, in which case such Holder shall pay that tax. The Conversion
Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than such Holder’s
name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding
sentence.

 

(f)          Upon
the conversion of an interest in a Global Note, the Trustee, or the Note Custodian at the direction of the Trustee, shall make
a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee
in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee.

 

    	32

    	 

    
 

(g)          Upon
conversion, a Holder of the Notes shall not receive any separate cash payment for accrued and unpaid interest, if any, except as
set forth below. The Company’s payment or delivery, as the case may be, of the Settlement Amount upon conversion of any Note
shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any,
to, but not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the
Conversion Date shall be deemed to be paid in full rather than canceled, extinguished or forfeited. Upon a conversion of Notes
into a combination of cash and shares of Common Stock, accrued and unpaid interest shall be deemed to be paid first out of the
cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular
Record Date, Holders of such Notes as of the close of business on such Regular Record Date shall receive the full amount of interest
payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion
during the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest
Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted; provided that
no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity Date;
(2) if the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the corresponding Interest
Payment Date; (3) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on
or prior to the corresponding Interest Payment Date; or (4) to the extent of any Defaulted Interest, if any Defaulted Interest
exists at the time of conversion with respect to such Note.

 

(h)          The
Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as
the holder of record of such shares as of the close of business on the relevant Conversion Date (if the Company elects to satisfy
the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company
elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes,
such Person shall no longer be a Holder of such Notes surrendered for conversion; provided that (a) the converting
Holder shall have the right to receive the Settlement Amount due upon conversion and (b) in the case of a conversion between
a Regular Record Date and the corresponding Interest Payment Date, the Holder of record as of the close of business on such Regular
Record Date shall have the right to receive the interest payable on such Interest Payment Date, in accordance with clause (g) above.

 

(i)          The
Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of
any fractional share of Common Stock issuable upon conversion based on the Daily VWAP on the relevant Conversion Date (in the case
of Physical Settlement) or based on the Daily VWAP on the last Trading Day of the relevant Observation Period (in the case of Combination
Settlement). For each Note surrendered for conversion, if the Company has elected Combination Settlement, the full number of shares
that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the applicable
Observation Period and any fractional shares remaining after such computation shall be paid in cash.

 

Section 8.03. Adjustment to Conversion
Rate upon Conversion upon a Make-Whole Fundamental Change. Article 16 If the Effective Date of a Make-Whole Fundamental Change
occurs prior to the Maturity Date and a Holder of the Notes elects to convert its Notes in connection with such Make-Whole Fundamental
Change, the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so surrendered for
conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. A
conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change
if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole
Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or,
in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the proviso in clause (b)
of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change).

 

    	33

    	 

    
 

(b)          Upon
surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall, at its option, satisfy
the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section
8.02; provided, however, that if, as of the Effective Date of a Make-Whole Fundamental Change described in clause
(b) of the definition of Fundamental Change, the Reference Property is composed entirely of cash, for any conversion of Notes following
the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock
Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the
Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion
Obligation shall be determined and paid to Holders of the Notes in cash on the third Business Day following the Conversion Date.
The Company shall notify the Holders of Notes, the Trustee and the Conversion Agent in writing of the Effective Date of any Make-Whole
Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective
Date.

 

(c)          The
number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table
below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”)
and the price (the “Stock Price”) paid (or deemed to be paid) per share of Common Stock in the Make-Whole Fundamental
Change. If the holders of Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change
described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise,
the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending
on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change.

 

(d)          The
Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate
of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such
adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment
giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional
Shares set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth
in Section 8.04.

 

    	34

    	 

    
 

(e)          The
following table sets forth the number of Additional Shares to be added to the Conversion Rate per $1,000 principal amount of Notes
pursuant to this Section 8.03 for each Stock Price and Effective Date set forth below:

 

	 	 Stock Price
	
Effective Date	$8.67	$10.00	$12.50	$15.00	$17.50	$20.00	$25.00	$30.00	$40.00	$50.00	$75.00	$100.00
	April 18, 2012	29.9030	23.2177	15.7806	11.6903	9.1938	7.5407	5.5024	4.2910	2.8939	2.0993	1.0901	0.6322

	May 1, 2018	29.9030	14.5628	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000

 

The exact Stock Prices and Effective Dates
may not be set forth in the table above, in which case:

 

(i)          if
the Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective Dates in the table,
the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set
forth for the higher and lower Stock Prices and the earlier and later Effective Dates based on a 365-day year, as applicable;

 

(ii)          if
the Stock Price is greater than $100.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the
column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate;
and

 

(iii)          if
the Stock Price is less than $8.67 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column
headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate.

 

Notwithstanding the foregoing, in no event
shall the Conversion Rate per $1,000 principal amount of Notes exceed 115.3402, subject to adjustment in the same manner as the
Conversion Rate pursuant to Section 8.04.

 

(f)          Nothing
in this Section 8.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 8.04 in respect of a Make-Whole Fundamental
Change.

 

Section 8.04. Adjustment of Conversion
Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except
that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case
of a share split or share combination), at the same time and upon the same terms as holders of the Common Stock and solely as a
result of holding the Notes, in any of the transactions described in this Section 8.04, without having to convert their Notes,
as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed
in thousands) of Notes held by such Holder of the Notes.

 

    	35

    	 

    
 

(a)          If
the Company exclusively issues shares of Common Stock as a dividend or distribution on its shares of Common Stock, or if the Company
effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula:

 

 

where,

 

	CR0	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on the Effective Date of such share split or share combination, as applicable;
	 	 
	CR1	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or Effective Date;
	 	 
	OS0	=	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date; and
	 	 
	OS1	=	the number of shares of Common Stock that will be outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

 

Any adjustment made under this Section 8.04(a) shall become
effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after
the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution
of the type described in this Section 8.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted,
effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that
would then be in effect if such dividend or distribution had not been declared.

 

    	36

    	 

    
 

(b)          If
the Company issues to all or substantially all holders of its shares of Common Stock any rights, options or warrants (other than
rights issued pursuant to a stockholder rights plan) entitling them, for a period of not more than 45 calendar days after the announcement
date of such issuance, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of
the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading
Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on the following
formula:

 

 

where,

 

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

 

Any increase made under this Section 8.04(b) shall be made successively
whenever any such rights, options or warrants are issued and shall become effective immediately after the open of business on the
Ex-Dividend Date for such issuance. To the extent that shares of Common Stock are not delivered after the expiration of such rights,
options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase
with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares
of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased
to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

 

For purposes of this Section 8.04(b) and
Section 8.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase
shares of Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading
Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, and in determining
the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the
Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration,
if other than cash, to be determined by the Board of Directors.

 

    	37

    	 

    
 

(c)          If
the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or
rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common
Stock, excluding Article 17 dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 8.04(a)
or Section 8.04(b), Article 18 dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant
to Section 8.04(d), and Article 19 Spin-Offs as to which the provisions set forth below in this Section 8.04(c) shall apply (any
of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire
Capital Stock or other securities of the Company, the “Distributed Property”), then the Conversion Rate shall
be increased based on the following formula:

 

 

where,

 

	CR0	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;
	 	 	 
	CR1	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;
	 	 	 
	SP0	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and
	 	 	 
	FMV	=	the fair market value (as determined by the Board of Directors) of the Distributed Property with respect to each outstanding share of Common Stock on the Ex-Dividend Date for such distribution.

 

Any increase made under the portion of this
Section 8.04(c) above shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution.
If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in
effect if such distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal
to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall
receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common
Stock receive the Distributed Property, the amount and kind of Distributed Property such Holder would have received if such Holder
owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If
the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this Section 8.04(c)
by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market
over the same period used in computing SP0.

 

    	38

    	 

    
 

With respect to an adjustment pursuant to
this Section 8.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital
Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company,
that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”),
the Conversion Rate shall be increased based on the following formula:

 

 

where,

 

	CR0	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such Spin-Off;
	 	 
	CR1	=	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such Spin-Off;
	 	 
	FMV0	=	the average of the Last Reported
    Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share
    of Common Stock (determined by reference to the definition of Last Reported Sale Price as set forth in Section 1.01 as if
    references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading
    Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and
	 	 
	MP0	=	the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

 

The adjustment to the Conversion Rate under the preceding paragraph
shall be determined on the last Trading Day of the Valuation Period but shall be given effect at the open of business on the Ex-Dividend
Date for such Spin-Off. Notwithstanding the foregoing, in respect of any conversion during the Valuation Period, references in
the portion of this Section 8.04(c) related to Spin-Offs to 10 consecutive Trading Days shall be deemed to be replaced with such
lesser number of Trading Days as have elapsed from, and including the Ex-Dividend Date of such Spin-Off to, but excluding, the
Conversion Date in determining the Conversion Rate. In addition, if the Ex-Dividend Date for the Spin-Off is less than 10 consecutive
Trading Days prior to, and including, the end of the Observation Period in respect of any conversion, references in the portion
of this Section 8.04(c) related to Spin-Offs to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion,
with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including,
the last Trading Day of such Observation Period.

 

If any such distribution that constitutes
a Spin-Off is declared but not made, and such distribution has resulted in an adjustment to the Conversion Rate, the Conversion
Rate shall be re-adjusted, effective as of the date the Board of Directors determines not to make such distribution, to be the
Conversion Rate that would then be in effect if such distribution had not been declared.

 

    	39

    	 

    
 

For purposes of this Section 8.04(c) (and
subject in all respects to Section 8.11), rights, options or warrants
distributed by the Company to all holders of its shares of Common Stock entitling them to subscribe for or purchase shares of the
Company’s Capital Stock, including shares of Common Stock (either initially or under certain circumstances), which rights,
options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to
be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances
of the shares of Common Stock, shall be deemed not to have been distributed for purposes of this Section 8.04(c) (and no adjustment
to the Conversion Rate under this Section 8.04(c) will be required)
until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed
and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 8.04(c). If any such
right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Supplemental
Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase
different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall
be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights
(in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by
any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants,
or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was
counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 8.04(c)
was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise
by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be readjusted as if such rights, options
or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution,
deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption
or purchase price received by a holder or holders of shares of Common Stock with respect to such rights, options or warrants (assuming
such holder had retained such rights, options or warrants), made to all holders of shares of Common Stock as of the date of such
redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without
exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued.

 

For purposes of Section 8.04(a),
Section 8.04(b) and this Section 8.04(c), if any dividend or distribution
to which this Section 8.04(c) is applicable also includes one or both of:

 

(A)          a
dividend or distribution of shares of Common Stock to which Section 8.04(a) is applicable (the “Clause A Distribution”);
or

 

(B)          a
dividend or distribution of rights, options or warrants to which Section 8.04(b) is applicable (the “Clause B Distribution”),

 

then (1) such dividend or distribution, other
than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section
8.04(c) is applicable (the “Clause C Distribution”)
and any Conversion Rate adjustment required by this Section 8.04(c) with respect to such Clause C Distribution shall then be made,
and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and
any Conversion Rate adjustment required by Section 8.04(a) and Section 8.04(b) with respect thereto shall then be made, except
that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution
shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause
A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the open of business
on such Ex-Dividend Date or effective date” within the meaning of Section 8.04(a) or “outstanding immediately prior
to the open of business on such Ex-Dividend Date” within the meaning of Section 8.04(b).

 

    	40

    	 

    
 

(d)          If
any cash dividend or distribution is made to all or substantially all holders of the shares of Common Stock (other than dividends
or distributions made in connection with the Company’s liquidation, dissolution, or winding up), the Conversion Rate shall
be adjusted based on the following formula:

 

 

where,

 

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

 

Any increase pursuant to this Section 8.04(d)
shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution.
If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of
Directors determines not to make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if
such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal
to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall
receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of Common Stock,
the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion
Rate on the Ex-Dividend Date for such cash dividend or distribution. For the avoidance of doubt, there will not be any adjustment
to the Conversion Rate under this Section 8.04(d) as a result of any distribution of Reference Property to holders of the Common
Stock in connection with any Merger Event.

 

    	41

    	 

    
 

(e)          If
the Company or any of its Subsidiaries makes a payment in respect of a tender or exchange offer for the Common Stock, to the extent
that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Last Reported
Sale Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant
to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula:

 

 

where,

 

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

 

The adjustment to the Conversion Rate under this Section 8.04(e)
shall be determined at the close of business on the 10th Trading Day immediately following, and including, the Trading Day
next succeeding the Expiration Date but shall be given effect at the open of business on the Trading Day next succeeding the Expiration
Date. Notwithstanding the foregoing, in respect of any conversion within the 10 Trading Days immediately following, and including,
the Trading Day next succeeding any Expiration Date, references in this Section 8.04(e) with respect to 10 Trading Days shall be
deemed replaced with such lesser number of Trading Days as have elapsed between such Expiration Date and the Conversion Date in
determining the Conversion Rate. In addition, if the Trading Day next succeeding the Expiration Date is less than 10 Trading Days
prior to, and including, the end of the Observation Period in respect of any conversion, references in this Section 8.04(e)
to 10 Trading Days shall be deemed to be replaced, solely in respect of that conversion, with such lesser number of Trading
Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, and including, the last Trading
Day of such Observation Period. For the avoidance of doubt, no adjustment under this Section 8.04(e) shall be made if such adjustment
would result in a decrease in the Conversion Rate.

 

(f)          Notwithstanding
anything to the contrary in this Section 8.04, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a
Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated
as the record holder of the shares of Common Stock as of the related Conversion Date as described under Section 8.02(h) based on
an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in this
Section 8.04, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead,
such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate
in the related dividend, distribution or other event giving rise to such adjustment.

 

    	42

    	 

    
 

(g)          Except
as stated herein, the Company shall not adjust the Conversion Rate for the issuance of shares of Common Stock or any securities
convertible into or exchangeable for shares of Common Stock or the right to purchase shares of Common Stock or such convertible
or exchangeable securities.

 

(h)          In
addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 8.04, and to the extent permitted
by applicable law and subject to the applicable rules of The New York Stock Exchange, (i) the Company may increase the Conversion
Rate of the Notes by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase
would be in the Company’s best interest and (ii) the Company may (but is not required to) increase the Conversion Rate
to avoid or diminish any income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with
a dividend or distribution of shares (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate
is increased pursuant to the preceding sentence, the Company shall mail to the Holder of each Note at its last address appearing
on the Security Register a notice of the increase at least 15 calendar days prior to the date the increased Conversion Rate takes
effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

 

(i)          Notwithstanding
anything to the contrary in Section 8.04, the Conversion Rate shall not be adjusted:

 

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

 

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

 

(iii)          upon
the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security
not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued, subject to Section
8.11;

 

(iv)          solely
for a change in the par value of the Common Stock; or

 

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

 

    	43

    	 

    
 

(j)          All
calculations and other determinations under this Article 8 shall be made by the Company and all calculations of the Conversion
Rate shall be made to the nearest one-ten thousandth (1/10,000) of a share.

 

(k)          Whenever
the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent
if not the Trustee) an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a
brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer shall have received such Officers’
Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without
inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate,
the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the
date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate to each Holder
of the Notes at its last address appearing on the Security Register. Failure to deliver such notice shall not affect the legality
or validity of any such adjustment.

 

(l)          For
purposes of this Section 8.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the
treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held
in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions
of shares of Common Stock.

 

Section 8.05. Adjustments of Prices.
Whenever any provision of the Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the
Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and, if applicable,
the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make
appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring
an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or Expiration Date, as the case may be, of the
event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or
the Daily Settlement Amounts are to be calculated.

 

Section 8.06. Shares to be Fully Paid.
The Company shall provide, free from preemptive rights, out of its authorized but unissued shares that are not reserved for other
purposes or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time
as such Notes are presented for conversion (assuming that at the time of computation of such number of shares, all such Notes would
be converted by a single Holder of the Notes and that Physical Settlement is applicable, and including the maximum number of Additional
Shares that could be included in the Conversion Rate for a conversion in connection with a Make-Whole Fundamental Change).

 

Section 8.07. Effect of Recapitalizations,
Reclassifications and Changes of the shares of Common Stock.

 

(a)          In
the case of:

 

    	44

    	 

    
 

(i)          any
recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination),

 

(ii)          any
consolidation, merger, combination or similar transaction involving the Company,

 

(iii)          any
sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s Subsidiaries substantially
as an entirety, or

 

(iv)          any
statutory share exchange,

 

in each case, as a result of which the shares
of Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or
any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger
Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount
of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination
thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event
would have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference
Property” meaning the kind and amount of Reference Property that a holder of one share of Common Stock would have received)
upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing
Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 6.01(c)
providing for such change in the right to convert each $1,000 principal amount of Notes; provided, however,
that at and after the effective time of the Merger Event (A) the Company shall continue to have the right to determine the form
of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 8.02 and (B)
(I) any amount payable in cash upon conversion of the Notes in accordance with Section 8.02 shall continue to be payable in cash,
(II) any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance
with Section 8.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares
of Common Stock would have been entitled to receive in such Merger Event and (III) the Daily VWAP shall be calculated based on
the value of a unit of Reference Property.

 

If the Merger Event causes the Common Stock
to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part
upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed
to be (A) the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively
make such an election or (B) if no holders of the shares of Common Stock affirmatively make such an election, the types and amounts
of consideration actually received by the holders of Common Stock, and (ii) the unit of Reference Property for purposes of the
immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common
Stock. If the holders receive only cash in such Merger Event, then for all conversions that occur after the effective date of such
Merger Event (x) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount
equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section
8.03), multiplied by the price paid per share of Common Stock in such Merger Event and (y) the Company shall satisfy the
Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the Conversion Date.
The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as
soon as practicable after such determination is made.

 

    	45

    	 

    
 

Such supplemental indenture described in
the second immediately preceding paragraph shall provide for adjustments that shall be as nearly equivalent as is possible to the
adjustments provided for in this Article 8. If, in the case of any Merger Event, the Reference Property includes shares of stock,
securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing
corporation, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person
and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall
reasonably consider necessary by reason of the foregoing, including to the extent required by the Board of Directors and practicable
the provisions providing for the purchase rights set forth in Article 9. Following any Merger Event, each reference herein to a
share of Common Stock shall be deemed to refer to a Unit of Reference Property, subject to the provisions of such supplemental
indenture.

 

(b)          In
the event the Company shall execute a supplemental indenture pursuant to subsection (a) of this Section 8.07, the Company shall
promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefore, the kind or amount of cash,
securities or property or asset that will comprise the Reference Property after any such Merger Event, any adjustment to be made
with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders
of the Notes. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder of the
Notes, at its address appearing on the Security Register, within 20 Business Days after execution thereof. Failure to deliver such
notice shall not affect the legality or validity of such supplemental indenture.

 

(c)          The
Company shall not become a party to any Merger Event unless its terms are consistent with this Section 8.07. None of the foregoing
provisions shall affect the right of a Holder of the Notes to convert its Notes into cash, shares of Common Stock or a combination
of cash and shares of Common Stock, as applicable, as set forth in Section 8.01 and Section 8.02 prior to the effective date of
such Merger Event.

 

(d)          The
above provisions of this Section shall similarly apply to successive Merger Events.

 

Section 8.08. Certain Covenants.
Article 20 The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable
by the Company and free from all taxes, liens and charges with respect to the issue thereof.

 

(b)          The
Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration
with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion,
the Company will, to the extent then permitted by the rules and interpretations of the Commission, secure such registration or
approval, as the case may be.

 

    	46

    	 

    
 

(c)          The
Company further covenants that if at any time the shares of Common Stock shall be listed on any national securities exchange or
automated quotation system the Company will list and keep listed, so long as the shares of Common Stock shall be so listed on such
exchange or automated quotation system, any share of Common Stock issuable upon conversion of the Notes.

 

Section 8.09. Responsibility of Trustee.
The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder of the Notes
to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including
any increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made,
or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same.
The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount)
of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion
of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor
any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock
or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to
comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality
of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of
any provisions contained in any supplemental indenture entered into pursuant to Section 8.07 relating either to the kind or amount
of shares of stock or securities or property (including cash) receivable by Holders of the Notes upon the conversion of their Notes
after any event referred to in such Section 8.07 or to any adjustment to be made with respect thereto, but, subject to the provisions
of Section 6.02 of the Base Indenture, may accept (without any
independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying
upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of
any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining
whether any event contemplated by Section 8.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible
therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section 8.01(b) with
respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may
conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent promptly after the occurrence
of any such event or at such other times as shall be provided for in Section 8.01(b).

 

Section 8.10. Notice to Holders of the
Notes Prior to Certain Actions. In case of any:

 

(a)          action
by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section 8.04
or Section 8.11;

 

    	47

    	 

    
 

(b)          Merger
Event or Consolidation Transaction; or

 

(c)          voluntary
or involuntary dissolution, liquidation or winding-up of the Company or any of its Subsidiaries;

 

then, in each case (unless notice of such event is otherwise
required pursuant to another provision of the Indenture, excluding for the avoidance of doubt Section 8.04(k)), the Company shall
cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be mailed to each Holder of the
Notes at its address appearing on the Security Register, as promptly as possible and at least 20 calendar days prior to the applicable
date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the
Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of shares of Common Stock
of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which
such Merger Event, Consolidation Transaction, dissolution, liquidation or winding-up is expected to become effective or occur,
and, if applicable, the date as of which it is expected that holders of shares of Common Stock of record shall be entitled to exchange
their shares of Common Stock for securities or other property deliverable upon such Merger Event, Consolidation Transaction, dissolution,
liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such
action by the Company or one of its Subsidiaries, Merger Event, Consolidation Transaction, dissolution, liquidation or winding-up.

 

Section 8.11. Shareholder Rights Plans.
If the Company has a rights plan in effect upon conversion of the Notes into Common Stock, each share of Common Stock, if any,
issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and any certificate representing
the share of Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms
of any such shareholder rights plan, as the same may be amended from time to time. If however, prior to any conversion, the rights
have separated from the shares of Common Stock in accordance with the provisions of the applicable shareholder rights plan, the
Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of
shares of Common Stock shares of Capital Stock of the Company, evidences of its indebtedness, assets, property, rights, options
or warrants to acquire its Capital Stock or other securities as provided in Section 8.04(c), subject to readjustment in the event
of the expiration, termination or redemption of such rights.

 

Article
9

Repurchase of Notes at Option of Holders

 

Section 9.01. Applicability of Article
XIII of the Base Indenture. Article XIII of the Base Indenture shall not apply to the Notes. Instead, the optional repurchase
provisions set forth in this Article 9 shall, with respect to the Notes, supersede in their entirety Article XIII of the Base Indenture,
and all references in the Base Indenture to Article XIII thereof and the optional repurchase provisions therein, as the case may
be, shall, with respect to the Notes, be deemed to be references to this Article 9 and the optional repurchase provisions set forth
in this Article 9.

 

    	48

    	 

    
 

Section 9.02. Repurchase at Option
of Holders of the Notes Upon a Fundamental Change. Article 21 If a Fundamental Change occurs at any time, each Holder of the
Notes shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s
Notes, or any portion of the principal thereof that is equal to $1,000 principal amount or an integral multiple of $1,000 principal
amount, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than
20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice at a repurchase price
equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding,
the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”); provided that if
the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which
such Regular Record Date relates, then the Company shall instead pay the full amount of accrued and unpaid interest to the Holder
of record on such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount
of Notes to be repurchased pursuant to this Article 9.

 

(b)          On
or before the 20th calendar day after the occurrence of a Fundamental Change, the Company shall provide to all Holders
of the Notes and the Trustee and the Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the “Fundamental
Change Company Notice”) of the occurrence of the effective date of the Fundamental Change and of the repurchase right
at the option of the Holders of the Notes arising as a result thereof. Each Fundamental Change Company Notice shall specify:

 

(i)          the
events causing the Fundamental Change;

 

(ii)          the
date of the Fundamental Change;

 

(iii)          the
last date on which a Holder of the Notes may exercise the repurchase right pursuant to this Article 9;

 

(iv)          the
Fundamental Change Repurchase Price;

 

(v)          the
Fundamental Change Repurchase Date;

 

(vi)          the
name and address of the Paying Agent and the Conversion Agent, if applicable;

 

(vii)          if
applicable, the Conversion Rate and any adjustments to the Conversion Rate;

 

(viii)          that
the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder of the Notes may be converted
only if such Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of the Indenture; and

 

(ix)          the
procedures that Holders of the Notes must follow to require the Company to repurchase their Notes.

 

    	49

    	 

    
 

At the Company’s request, the Trustee
shall give such notice in the Company’s name and at the Company’s expense; provided, however, that, in
all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company.

 

Such notice shall be by first class mail
to the Trustee, to the Paying Agent and to each Holder of the Notes at its address shown in the Security Register (and to beneficial
owners as required by applicable law) or, in the case of Global Notes, in accordance with Applicable Procedures. Simultaneously
with providing such notice, the Company shall publish a notice containing the information set forth in the Fundamental Change Company
Notice in a newspaper of general circulation in The City of New York or publish such information on the Company’s website
or through such other public medium as the Company may use at that time.

 

No failure of the Company to give the foregoing
notices and no defect therein shall limit the repurchase rights of the Holders of the Notes or affect the validity of the proceedings
for the repurchase of the Notes pursuant to this Section 9.02.

 

(c)          Repurchases
of Notes under this Section 9.02 shall be made, at the option of the Holder of the Notes thereof, upon:

 

(i)          delivery
to the Paying Agent by a Holder of the Notes of a duly completed notice (the “Fundamental Change Repurchase Notice”)
in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in
compliance with the Depositary’s procedures for surrendering interests in Global Notes, if the Notes are Global Notes, in
each case on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date;
and

 

(ii)          delivery
of the Notes, if the Notes are Physical Notes, to the Paying Agent at any time after delivery of the Fundamental Change Repurchase
Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or book-entry
transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each case such delivery
being a condition to receipt by the Holder of the Notes of the Fundamental Change Repurchase Price therefor.

 

(d)          The
Fundamental Change Repurchase Notice in respect of any Notes to be repurchased shall state:

 

(i)          in

(ii)          the
portion of the principal amount of the Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and

 

(iii)          that

    	50

    	 

    
 

Notwithstanding anything herein to the contrary,
any Holder of the Notes delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 9.02
shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close
of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of
withdrawal to the Paying Agent in accordance with Section 9.03.

 

The Paying Agent shall promptly notify the
Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.

 

(e)          Notwithstanding
the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders of the Notes upon a Fundamental
Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to
such date (except in the case of an acceleration resulting from a default by the Company in the payment of the Fundamental Change
Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders of the Notes thereof
any Physical Notes held by it during the acceleration of the Notes (except in the case of an acceleration resulting from a default
by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry
transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been canceled, and, upon such
return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have
been withdrawn.

 

Section 9.03. Withdrawal of Fundamental
Change Repurchase Notice. A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written
notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 9.03 at any time
prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying:

 

(i)          the
principal amount of the Notes with respect to which such notice of withdrawal is being submitted;

 

(ii)          if
Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is being submitted;
and

 

(iii)          the
principal amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice which portion
must be in principal amounts of $1,000 or an integral multiple of $1,000;

 

provided, however, that if the Notes are Global
Notes, the notice must comply with Applicable Procedures.

 

Section 9.04. Deposit of Fundamental
Change Repurchase Price. Article 22 The Company shall deposit with the Trustee (or other Paying Agent appointed by the Company,
or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 10.03 of
the Base Indenture) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date an amount of
money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject
to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered
for repurchase (and not withdrawn prior to the close of business on the Business Day immediately preceding the Fundamental Change
Repurchase Date) will be made on the later of (i) the Fundamental Change Repurchase Date with respect to such Note (provided
the Holder of the Notes has satisfied the conditions in Section 9.02) and (ii) the time of book-entry transfer or the delivery
of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section
9.02 by mailing checks for the amount payable to the Holders of
such Notes entitled thereto as they shall appear in the Security Register; provided, however, that payments to the
Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee
shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental
Change Repurchase Price.

 

    	51

    	 

    
 

(b)          If
by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date the Trustee (or other Paying Agent appointed by the
Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental
Change Repurchase Date then:

 

(i)          such
Notes shall cease to be Outstanding,

 

(ii)          interest
shall cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered
to the Trustee or Paying Agent), and

 

(iii)          all
other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price
and, if the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the related Interest Payment
Date, the right of the Holder of record on such Regular Record Date to receive the related interest payment).

 

(c)          Upon
surrender of a Note that is to be repurchased in part pursuant to Section 9.02, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder a new Note in an authorized denomination equal in principal amount to the unrepurchased
portion of the Note surrendered, without payment of any service charge.

 

Section 9.05. Covenant to Comply with
Applicable Laws Upon Repurchase of Notes. In connection with any repurchase offer pursuant to a Fundamental Change Company
Notice, the Company shall, if required:

 

(a)          comply
with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable;

 

(b)          file
a Schedule TO or any other required schedule under the Exchange Act; and

 

(c)          otherwise
comply with all federal and state securities laws in connection with any offer by the Company to repurchase the Notes;

 

in each case, so as to permit the rights and
obligations under this Article 9 to be exercised in the time and in the manner specified in this Article 9.

Optional Redemption

 

Section 10.01. Applicability of Article
XI of the Base Indenture. Article XI of the Base Indenture shall not apply to the Notes. Instead the redemption provisions
set forth in this Article 10 shall, with respect to the Notes, supersede in their entirety Article XI of the Base Indenture, and
all references in the Base Indenture to Article XI thereof and the redemption provisions therein, as the case may be, shall, with
respect to the Notes, be deemed to be references to this Article 10 or the redemption provisions set forth in this Article 10,
respectively.

 

Section 10.02. Optional Redemption.
No sinking fund is provided for the Notes. If the purchase and sale agreement relating to the Company’s pending acquisition
of Walker Group Holdings LLC terminates, the Company may redeem (an “Optional Redemption”) all, but not less
than all, of the outstanding Notes for cash on a Redemption Date to occur on or prior to August 31, 2012, at a redemption price
(the “Redemption Price”) for each $1,000 principal amount of Notes to be redeemed equal to the sum of (i) $1,010,
(ii) accrued and unpaid interest on such Notes to, but excluding, the Redemption Date and (iii) 75% of the excess, if any, of the
Redemption Conversion Value over the Initial Conversion Value (unless the Redemption Date falls after a Regular Record Date but
on or prior to the immediately succeeding Interest Payment Date, in which case the Company shall pay the full amount of accrued
and unpaid interest to Holders of record of such Notes as of the close of business on such Regular Record Date, and the Redemption
Price shall not include any accrued and unpaid interest on the Notes). Following August 31, 2012, the Notes shall not be redeemable
at the Company’s option.

 

Section 10.03. Notice of Optional Redemption;
Selection of Notes.

 

(a)          In
case the Company exercises its Optional Redemption right to redeem the Notes pursuant to Section 10.02, it shall fix a date, which
must be a Business Day, for redemption (each, a “Redemption Date”), and it or, at its written request received
by the Trustee not less than 60 calendar days prior to the Redemption Date (or such shorter period of time as may be acceptable
to the Trustee), the Trustee, in the name of and at the expense of the Company, shall provide or cause to be provided by mail or
electronic delivery a notice of such Optional Redemption (a “Redemption Notice”) not less than 45 nor more than
60 calendar days prior to the Redemption Date to the Paying Agent, the Conversion Agent and each Holder of Notes so to be redeemed
at its last address as the same appears on the Security Register; provided, however, that if the Company shall give
such notice, it shall also give written notice of the Redemption Date to the Trustee.

 

(b)          The
Redemption Notice, if sent by mail or electronic delivery in the manner herein provided, shall be conclusively presumed to have
been duly given, whether or not the Holder of any Note receives such notice. In any case, failure to give such Redemption Notice
by mail or electronic delivery or any defect in the Redemption Notice to the Holder of any Note designated for redemption shall
not affect the validity of the proceedings for the redemption of any other Note.

 

    	53

    	 

    
 

(c)          Each
Redemption Notice shall specify:

 

(i)          the
Redemption Date;

 

(ii)          the
Redemption Price (or manner of calculation if not then known);

 

(iii)          that
on the Redemption Date, the Redemption Price will become due and payable upon each such Note, and that interest thereon, if any,
shall cease to accrue on and after said date;

 

(iv)          the
place or places where such Notes are to be surrendered for payment of the Redemption Price;

 

(v)          that
Holders of the Notes may surrender their Notes for conversion at any time prior to the close of business on the Business Day immediately
preceding the Redemption Date;

 

(vi)          the
procedures a converting Holder of the Notes must follow to convert its Notes and the Settlement Method and Specified Cash Amount,
if applicable;

 

(vii)          the
Conversion Rate and, if applicable, the number of Additional Shares added to the Conversion Rate in accordance with Section 8.03;
and

 

(viii)          the
CUSIP, ISIN or other similar numbers, if any, assigned to such Notes.

 

A Redemption Notice shall be irrevocable.

 

Section 10.04. Payment of Notes Called
for Redemption.

 

(a)          If
any Redemption Notice has been given in respect of the Notes in accordance with Section 10.03, the Notes shall become due and payable
on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price. On presentation
and surrender of the Notes at the place or places stated in the Redemption Notice, the Notes shall be paid and redeemed by the
Company at the applicable Redemption Price.

 

(b)          Prior
to 11:00 a.m. on the Redemption Date, the Company shall deposit with the Paying Agent or, if the Company or a Subsidiary of the
Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 10.03 of the Base Indenture an
amount of cash (in immediately available funds if deposited on the Redemption Date), sufficient to pay the Redemption Price of
all of the Notes to be redeemed on such Redemption Date. Subject to receipt of funds by the Paying Agent, payment for the Notes
to be redeemed shall be made promptly after the later of:

 

(i)          the
Redemption Date for such Notes; and

 

    	54

    	 

    
 

(ii)          the
time of presentation of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the
manner required by this Section 10.04.

 

The Paying Agent shall, promptly after such
payment and upon written demand by the Company, return to the Company any funds in excess of the Redemption Price.

 

Section 10.05. Restrictions on Redemption.
The Company may not redeem any Notes if the principal amount of the Notes has been accelerated under Section 5.03, and such acceleration
has not been rescinded, on or prior to the Redemption Date (except in the case of an acceleration resulting from a Default by the
Company in the payment of the Redemption Price with respect to such Notes). Except in the case of an acceleration resulting from
a Default by the Company in the payment of the Redemption Price with respect to such Notes, the Paying Agent will promptly return
to the respective Holders of the Notes thereof any Physical Notes held by it during the acceleration of the Notes, or any instructions
for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been canceled,
and, upon such return or cancellation, as the case may be, the Redemption Notice with respect thereto shall be deemed to have been
withdrawn.

[FORM OF REVERSE OF NOTE]

 

WABASH NATIONAL CORPORATION

3.375% Convertible Senior Note due 2018

 

This Note is one of a duly authorized issue
of Securities of the Company, designated as its 3.375% Convertible Senior Notes due 2018 (the “Notes”), limited
to the aggregate principal amount of $150,000,000 all issued or to be issued under and pursuant to an Indenture dated as of April
23, 2012 (the “Base Indenture”), as amended and supplemented by the First Supplemental Indenture dated as of
April 23, 2012 (herein called the “Supplemental Indenture”; the Base Indenture, as amended and supplemented
by the Supplemental Indenture, and as it may be further amended or supplemented from time to time, the “Indenture”),
by and between the Company and Wells Fargo Bank, National Association (the “Trustee”) to which Indenture and
all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations,
duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an
unlimited aggregate principal amount, subject to certain conditions specified in the Indenture.

 

In case an Event of Default, as defined
in the Indenture, shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either
the Trustee or Holders of at least 25% in aggregate principal amount of Notes then Outstanding, and upon said declaration shall
become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture.

 

Subject to the terms and conditions of the
Indenture, the Company will make all payments and deliveries in respect of the Redemption Price, the Fundamental Change Repurchase
Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent
to collect such payments in respect of the Note. The Company shall pay cash amounts in money of the United States that at the time
of payment is legal tender for payment of public and private debts.

 

The Indenture contains provisions permitting
the Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances,
with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time Outstanding,
evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as
described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate
principal amount of the Notes at the time Outstanding may on behalf of the Holders of all of the Notes waive any past Default or
Event of Default under the Indenture and its consequences.

 

No reference herein to the Indenture and
no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional,
to pay the principal (including the Fundamental Change Repurchase Price, if applicable) of, the Redemption Price, if applicable,
of, and accrued and unpaid interest on, and the consideration due upon conversion of, this Note at the place, at the respective
times, in the amounts and, if applicable, in the lawful money herein prescribed.

 

    	5

    	 

    
 

The Notes are issuable in registered form
without coupons in denominations of $1,000 principal amount and integral multiples thereof. At the office or agency of the Company
referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged
for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if
required by the Company or Trustee, with payment of a sum sufficient to cover any transfer tax or similar governmental charge required
by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange
of Notes being different from the name of the Holder of the old Notes surrendered for such exchange.

 

The Notes shall be redeemable at the Company’s
option in accordance with the terms and conditions specified in the Indenture.
