ARTICLE 2

ISSUE, DESCRIPTION, EXECUTION, REGISTRATION

AND EXCHANGE OF NOTES


 


Section 2.01. Designation Amount and Issue of Notes.



 


The Notes shall be designated as “3.75%
Exchangeable Senior Notes due 2024.” Upon the execution of this Indenture, the Initial Notes may be executed by the Issuer
and delivered to the Trustee for authentication, and the Trustee shall thereupon authenticate and deliver Notes upon a written
order of the Issuer (an “Authentication Order”), such order signed by one Officer, and an Opinion of Counsel
as to, among other things, the enforceability of this Indenture and the Initial Notes. At any time and from time to time thereafter,
the Trustee shall, upon receipt of an Authentication Order, authenticate and deliver any Additional Notes in an aggregate principal
amount specified in such Authentication Order for such Additional Notes issued hereunder and, in the case of any issuance of Additional
Notes pursuant to Section 2.01, such Authentication Order shall certify that such issuance is in compliance with this Indenture.


 




    	13



     


    

 


The aggregate principal amount of Notes which may be authenticated
and delivered under this Indenture is unlimited; provided that upon initial issuance, the aggregate principal amount of
Notes outstanding shall not exceed $125,000,000 (or $143,750,000 if the Initial Purchasers’ option to purchase additional
Notes is exercised in full) (the “Initial Notes”), except as provided in Section 2.06. The Issuer may, without
notice to or the consent of the Holders of Notes, issue additional Notes (the “Additional Notes”) under this
Indenture from time to time in the future with the same terms as the Initial Notes (other than differences in the issue date, the
issue price and interest accrued prior to the issue date of such Additional Notes) in an unlimited aggregate principal amount,
provided that if any such Additional Notes are not fungible with the Initial Notes for U.S. federal income tax purposes,
such Additional Notes will have a separate CUSIP number. The Initial Notes and any such Additional Notes shall constitute a single
series of debt securities, and in circumstances in which this Indenture provides for the Holders of Notes to vote or take any action,
the Holders of Initial Notes and the Holders of any such Additional Notes will vote or take that action as a single class.


 


Section 2.02. Form of Notes.


 


The Notes and the Trustee’s certificate
of authentication to be borne by such Notes shall be substantially in the form set forth in Exhibit A hereto. The terms
and provisions contained in the form of Note attached as Exhibit A hereto shall constitute, and are hereby expressly made,
a part of this Indenture and, to the extent applicable, the Issuer and the Trustee, by their execution and delivery of this Indenture,
expressly agree to such terms and provisions and to be bound thereby.


 


Any of the Notes may have such letters,
numbers or other marks of identification and such notations, legends, endorsements or changes as the officer(s) executing the same
may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this
Indenture, or as may be required by the Custodian or the Depositary or as may be required for the Notes to be tradable on any market
developed for trading of securities pursuant to Rule 144A or as may be required to comply with any applicable law or with any rule
or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on
which the Notes may be listed, or to conform to usage, or to indicate any special limitations or restrictions to which any particular
Notes are subject.


 


So long as the Notes are eligible for book-entry
settlement with the Depositary, or unless otherwise required by law, or otherwise contemplated by Section 2.05(b), all of the Notes
will be represented by one or more Notes in global form registered in the name of the Depositary or the nominee of the Depositary
(a “Global Note”). The transfer and exchange of beneficial interests in any such Global Note shall be effected
through the Depositary in accordance with this Indenture and the applicable procedures of the Depositary. Except as provided in
Section 2.05(b), beneficial owners of a Global Note shall not be entitled to have certificates registered in their names, will
not receive or be entitled to receive physical delivery of certificates in definitive form, and will not be considered Holders
of such Global Note.


 


Any Global Note shall represent such of
the outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate amount of outstanding
Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to
time be increased or reduced to reflect repurchases, exchanges, or transfers permitted hereby. Any endorsement of a Global Note
to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee
or the Custodian, at the direction of the Trustee, in such manner and upon instructions given by the Holder of such Notes in accordance
with this Indenture. Payment of principal of and Interest on any Global Note shall be made to the Holder of such Note.


 


Section 2.03. Date and Denomination of Notes; Payments
of Interest and Defaulted Amounts.


 


(a)  The Notes shall be issuable in registered
form without coupons in minimum denominations of $1,000 principal amount and in integral multiples of $1,000 in excess thereof.
Each Note shall be dated the date of its authentication and shall bear cash Interest at a per annum rate equal to 3.75% from the
date specified on the face of the form of Note attached as Exhibit A hereto. Interest on the Notes shall be computed on
the basis of a 360-day year consisting of twelve 30-day months and, for a partial month, on the basis of the number of days actually
elapsed in a 30-day month.


 




    	14



     


    

 


(b)  The Person in whose name any Note is
registered on the Note Register at the Close of Business on any Regular Record Date with respect to any Interest Payment Date shall
be entitled to receive the Interest payable on such Interest Payment Date, subject to the provisions of Section 13.02(a) relating
to any Note or portion thereof surrendered for exchange during the period from the Close of Business on the Regular Record Date
for any Interest Payment Date to the Close of Business on the applicable Interest Payment Date. Interest on any Global Note shall
be paid by wire transfer of immediately available funds to the account of the Depositary or its nominee. Payment of the principal
of Notes not represented by a Global Note shall be made at the office or agency designated by the Issuer for such purpose. Interest
on Notes not represented by a Global Note shall be paid (i) if such Holder holds $2,000,000 or less aggregate principal amount
of Notes, by check mailed to such Holder’s registered address, and (ii) if such Holder holds more than $2,000,000 aggregate
principal amount of Notes, (A) by check mailed to such Holder’s registered address or, (B) if such Holder has previously
delivered to the Note Registrar a written instruction, that is satisfactory to the Note Registrar, requesting the Issuer make such
subsequent payments by wire transfer to an account of such Holder which is located within the United States, for each subsequent
interest payment until such Holder delivers to the Note Registrar a new written instruction to the contrary.


 


If a payment date is not a Business Day,
payment shall be made on the next succeeding Business Day, and no additional interest on such payment shall accrue in respect of
the delay. The term “Regular Record Date” means, with respect to any Interest Payment Date, March 1 (whether
or not a Business Day) or September 1 (whether or not a Business Day), as the case may be, immediately preceding such Interest
Payment Date.


 


(c)  Any Defaulted Amounts shall forthwith
cease to be payable to the Holder on the relevant payment date but shall accrue interest per annum at the rate borne by the Notes
from, and including, such relevant payment date, and such Defaulted Amounts together with such interest thereon shall be paid by
the Issuer, at its election in each case, as provided in clause (1) or (2) below:


 


		(1)	The Issuer may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes are registered at the
Close of Business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner:
The Issuer shall notify the Trustee in writing of the amount of the Defaulted Amounts proposed to be paid on each Note and the
date of the proposed payment (which shall be not less than 20 calendar days after the receipt by the Trustee of such notice, unless
the Trustee shall consent to an earlier date), and at the same time the Issuer shall deposit with the Trustee an amount of money
equal to the aggregate amount to be paid in respect of such Defaulted Amounts 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 Amounts as in this clause provided. Thereupon the Issuer shall fix a special record date
for the payment of such Defaulted Amounts which shall be not more than 15 calendar days and not less than 10 calendar days prior
to the date of the proposed payment. At least 15 calendar days before the special record date, the Issuer (or, upon the written
request of the Issuer, the Trustee in the name and at the expense of the Issuer) shall deliver or cause to be delivered to Holders
a notice stating the special record date, the related payment date and the amount of such Defaulted Amounts to be paid to each
such Holder.



 


		(2)	The Issuer may make payment of any Defaulted Amounts in any other lawful manner not inconsistent with the requirements of any
securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice
as may be required by such exchange or automated quotation system, if, after notice given by the Issuer to the Trustee of the proposed
payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.



 




    	15



     


    

 


Section 2.04. Execution of Notes.


 


The Notes shall be signed in the name and
on behalf of the Issuer by the manual or facsimile signature of one or more Officers. Only such Notes as shall bear thereon a certificate
of authentication substantially in the form set forth on the form of Note attached as Exhibit A hereto, executed manually
by the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 7.11), shall be entitled to the benefits
of this Indenture or be valid or obligatory for any purpose. A Note will not be valid or obligatory for any purpose until authenticated
by the manual signature of the Trustee (or such an authenticating agent). Such certificate by the Trustee (or such an authenticating
agent) upon any Note executed by the Issuer shall be conclusive evidence that the Note so authenticated has been duly authenticated
and delivered hereunder and that the Holder is entitled to the benefits of this Indenture.


 


In case any Officer who shall have signed
any of the Notes shall cease to be such Officer before the Notes so signed shall have been authenticated and delivered by the Trustee,
or disposed of by the Issuer, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who
signed such Notes had not ceased to be such Officer, and any Note may be signed on behalf of the Issuer by such persons as, at
the actual date of the execution of such Note, shall be the proper Officers, although at the date of the execution of this Indenture
any such person was not such an Officer.


 


Section 2.05. Exchange and Registration of Transfer of
Notes; Restrictions on Transfer.


 


(a)  The Issuer shall cause to be kept initially
at the Corporate Trust Office a register (the register maintained in such office and in any other office or agency of the Issuer
designated pursuant to Section 4.02 being herein sometimes collectively referred to as the “Note Register”)
in which, subject to such reasonable regulations as it may prescribe, the Issuer shall provide for the registration of Notes and
of transfers of Notes. The Trustee is hereby appointed “Note Registrar” for the purpose of registering Notes
and transfers of Notes as herein provided. The Issuer may appoint one or more co-registrars in accordance with Section 4.02.


 


Upon surrender for registration of transfer
of any Note to the Note Registrar or any co-registrar, and satisfaction of the requirements for such transfer set forth in this
Section 2.05, the Issuer shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such
restrictive legends as may be required by this Indenture.


 


Notes may be transferred for other Notes
of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be transferred at any
such office or agency maintained by the Issuer pursuant to Section 4.02. Whenever any Notes are so surrendered for transfer, the
Issuer shall execute, and the Trustee shall authenticate and deliver, the Notes which the Noteholder making the transfer is entitled
to receive bearing registration numbers not contemporaneously outstanding.


 


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


 


All Notes presented or surrendered for registration
of transfer shall (if so required by the Issuer or the Note Registrar) be duly endorsed, or be accompanied by a written instrument
or instruments of transfer in form satisfactory to the Issuer, and the Notes shall be duly executed by the Noteholder thereof or
its attorney duly authorized in writing.


 




    	16



     


    

 


No service charge shall be made to any Holder
for any registration of, transfer of Notes, but the Issuer may require payment by the Holder of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes.


 


(b)  The following provisions shall apply
only to Global Notes:


 


		(1)	Each Global Note authenticated under this Indenture shall be registered in the name of the Depositary or a nominee thereof
and delivered to such Depositary or a nominee thereof or Custodian therefor, and each such Global Note shall constitute a single
Note for all purposes of this Indenture.



 


		(2)	Notwithstanding any other provision in this Indenture, no Global Note may be transferred in whole or in part for Notes registered,
and no transfer of a Global Note in whole or in part may be registered, in the name of any Person other than the Depositary or
a nominee thereof unless (1) the Depositary (x) has notified the Issuer that it is unwilling or unable to continue as Depositary
for such Global Note or (y) has ceased to be a clearing agency registered under the Exchange Act, and a successor depositary has
not been appointed by the Issuer within ninety (90) calendar days, or (2) an Event of Default has occurred and is continuing. Any
Global Note exchanged pursuant to clause (1) or (2) above shall be so transferred in whole and not in part. Any Note issued in
exchange for a Global Note or any portion thereof shall be a Global Note; provided that any such Note so issued that is
registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Note.



 


		(3)	Notes issued in exchange for a Global Note or any portion thereof pursuant to clause (2) above shall be issued in definitive,
fully registered form, without Interest coupons, shall have an aggregate principal amount equal to that of such Global Note or
portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary
shall designate and shall bear any legends required hereunder. Any Global Note to be transferred in whole shall be surrendered
by the Depositary to the Trustee, as Note Registrar. With regard to any Global Note to be transferred in part, either such Global
Note shall be so surrendered for transfer or, if the Trustee is acting as Custodian for the Depositary or its nominee with respect
to such Global Note, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so transferred,
by means of an appropriate adjustment made on the records of the Note Registrar. Upon any such surrender or adjustment, the Trustee
shall authenticate and make available for delivery the Note issuable on such transfer to or upon the written order of the Depositary
or an authorized representative thereof.



 


		(4)	In the event of the occurrence of any of the events specified in clause (2) above, the Issuer will promptly make available
to the Trustee a reasonable supply of certificated Notes in definitive, fully registered form, without Interest coupons.



 


		(5)	Neither any members of, or participants in, the Depositary (“Agent Members”) nor any other Persons on whose
behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Note registered in the name
of the Depositary or any nominee thereof, and the Depositary or such nominee, as the case may be, may be treated by the Issuer,
the Trustee and any agent of the Issuer or the Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee from
giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case
may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the
operation of customary practices of such Persons governing the exercise of the rights of a Holder of any Note.



 




    	17



     


    

 


 


		(6)	At such time as all interests in a Global Note have been repurchased, exchanged, or canceled for Notes in certificated form,
such Global Note shall, upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and instructions
existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is
repurchased, exchanged, or canceled for Notes in certificated form, the principal amount of such Global Note shall, in accordance
with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced, and
an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect
such reduction.



 


(c)  Every Note (and all securities issued
in exchange therefor or in substitution thereof) that bears or is required under this Section 2.05(c) to bear the legend set forth
in this Section 2.05(c) (the “Restricted Notes Legend”), and any Common Stock that bears or is required under
this Section 2.05(c) to bear the Common Stock legend set forth in this Section 2.05(c) (the “Common Stock Legend”)
(collectively, the “Restricted Notes”) shall be subject to the restrictions on transfer set forth in this Section
2.05(c) (including those set forth in the legends below) unless such restrictions on transfer shall be waived by written consent
of the Issuer, and the Holder of each such Restricted Note, by such Holder’s acceptance thereof, agrees to be bound by all
such restrictions on transfer. As used in this Section 2.05(c), the term “transfer” means any sale, pledge,
loan, transfer or other disposition whatsoever of any Restricted Note or any interest therein.


 


Until the Maturity Date for the Notes, every
certificate evidencing the Notes shall bear a Restricted Notes Legend in substantially the following form unless otherwise determined
by the Issuer in writing, with written notice thereof delivered to the Trustee:


 


THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION.

BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT (“RULE 144A”)); (2) AGREES ON ITS OWN BEHALF AND ON

Any such shares of Common Stock as to which
such restrictions on transfer shall have expired in accordance with their terms or as to which the conditions for removal of the
Common Stock Legend set forth therein have been satisfied may, upon surrender of the certificates representing such shares of Common
Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate
or certificates for a like number of shares of Common Stock, which shall not bear the Common Stock Legend required by this Section
2.05(c).


 


(d)  By its acceptance of any Note bearing
the Restricted Notes Legend, each Holder of such Note acknowledges the restrictions on transfer of such Note set forth in this
Indenture and in the Restricted Notes Legend and agrees that it will transfer such Note only as provided in this Indenture and
as permitted by applicable law.


 


(e)  Any Restricted Securities purchased
or owned by the Issuer or any Affiliate thereof may not be resold by the Issuer or such Affiliate unless registered under the Securities
Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction which results
in such Notes or Common Stock, as the case may be, no longer being “restricted securities” (as defined under Rule 144).

(f)  The Trustee in each of its various capacities
as designated from time to time hereunder shall have no responsibility or obligation to any Agent Members or any other Person with
respect to the accuracy of the books or records, or the acts or omissions, of the Depositary or its nominee or of any participant
or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any Agent Member or other
Person (other than the Depositary) of any notice or the payment of any amount, under or with respect to such Notes. All notices
and communications to be given to the Noteholders and all payments to be made to Noteholders under the Notes shall be given or
made only to or upon the order of the registered Noteholders (which shall be the Depositary or its nominee in the case of a Global
Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to the customary
procedures of the Depositary. The Trustee in each of its various capacities as designated from time to time hereunder may rely
and shall be fully protected in relying upon any information furnished by the Depositary with respect to its Agent Members.


 


The Trustee in each of its various capacities
as designated from time to time hereunder shall have no obligation or duty to monitor, determine or inquire as to compliance with
any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest
in any Note (including any transfers between or among Agent Members in any Global Indenture) other than to require delivery of
such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required
by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements
hereof.


 


Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes.



 


In case any Note shall become mutilated
or be destroyed, lost or stolen, the Issuer in its discretion may execute, and upon its written request the Trustee or an authenticating
agent appointed by the Trustee shall authenticate and make available for delivery, a new Note, bearing a number not contemporaneously
outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed,
lost or stolen. In every case, the applicant for a substituted Note shall furnish to the Issuer, to the Trustee and, if applicable,
to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss,
liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the
applicant shall also furnish to the Issuer, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction
of the destruction, loss or theft of such Note and of the ownership thereof.


 


Following receipt by the Trustee or such
authenticating agent, as the case may be, of satisfactory security or indemnity and evidence, as described in the preceding paragraph,
the Trustee or such authenticating agent may authenticate any such substituted Note and make available for delivery such Note.
Upon the issuance of any substituted Note, the Issuer may require the payment by the Holder of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In
case any Note which has matured or is about to mature or has been properly tendered for repurchase on a Fundamental Change Repurchase
Date (and not withdrawn) or is to be exchanged pursuant to this Indenture, shall become mutilated or be destroyed, lost or stolen,
the Issuer may, instead of issuing a substitute Note, pay or authorize the payment of or exchange or authorize the exchange of
the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment
or exchange shall furnish to the Issuer, to the Trustee and, if applicable, to such authenticating agent such security or indemnity
as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or in connection with
such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Issuer, the Trustee
and, if applicable, any Paying Agent or Exchange Agent evidence to their satisfaction of the destruction, loss or theft of such
Note and of the ownership thereof.


 




    	20



     


    

 


Every substitute Note issued pursuant to
the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional
contractual obligation of the Issuer, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be
entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately
with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the
express condition that the foregoing provisions are exclusive with respect to the replacement or payment or exchange or repurchase
of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or
statute existing or hereafter enacted to the contrary with respect to the replacement or payment or exchange or repurchase of negotiable
instruments or other securities without their surrender.


 


Section 2.07. Temporary Notes.


 


Pending the preparation of Notes in certificated
form, the Issuer may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon the written request
of the Issuer, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized
denomination, and substantially in the form of the Notes in certificated form, but with such omissions, insertions and variations
as may be appropriate for temporary Notes, all as may be determined by the Issuer. Every such temporary Note shall be executed
by the Issuer and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same
manner, and with the same effect, as the Notes in certificated form. Without unreasonable delay, the Issuer will execute and deliver
to the Trustee or such authenticating agent Notes in certificated form and thereupon any or all temporary Notes may be surrendered
in exchange therefor, at each office or agency maintained by the Issuer pursuant to Section 4.02 and the Trustee or such authenticating
agent shall authenticate and make available for delivery in exchange for such temporary Notes an equal aggregate principal amount
of Notes in certificated form. Such exchange shall be made by the Issuer at its own expense and without any charge therefor. Until
so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under
this Indenture as Notes in certificated form authenticated and delivered hereunder.


 


Section 2.08. Cancellation of Notes.


 


All Notes surrendered for the purpose of
payment, repurchase, exchange or registration of transfer shall, if surrendered to the Issuer or any paying agent to whom Notes
may be presented for payment (the “Paying Agent”) or Exchange Agent, both of which shall initially be the Trustee,
or any Note Registrar, be surrendered to the Trustee and promptly canceled by it or, if surrendered to the Trustee, shall be promptly
canceled by it and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture.
The Trustee shall dispose of such canceled Notes in accordance with its customary procedures. If the Issuer shall acquire any of
the Notes, such acquisition shall not operate as a repurchase or satisfaction of the indebtedness represented by such Notes unless
and until the same are delivered to the Trustee for cancellation.


 


Section 2.09. CUSIP Numbers.


 


The Issuer in issuing the Notes may use
“CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices
issued to Holders as a convenience to such Holders; provided that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on
the other identification numbers printed on the Notes. The Issuer shall promptly notify the Trustee in writing of any change in
the “CUSIP” numbers.

ARTICLE 3

REPURCHASE OF NOTES


 


Section 3.01. Repurchases at Option of Holders upon a
Fundamental Change.


 


(a)  If a Fundamental Change occurs, then
each Holder shall have the right, at such Holder’s option, to require the Issuer to repurchase for cash any or all of such
Holder’s Notes, or any portion thereof such that the remaining principal amount that remains outstanding of each Note that
is not repurchased in full equals $1,000 or an integral multiple of $1,000 in excess thereof, on a date (the “Fundamental
Change Repurchase Date”) specified by the Issuer that is not less than 20 calendar days or more than 35 calendar days
following the date on which the Issuer delivers the Fundamental Change Repurchase Notice to the Holders, at a repurchase price
equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid Interest thereon, if any,
to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”); provided,
however, that if the Fundamental Change Repurchase Date falls after a Regular Record Date and on or prior to the Interest
Payment Date corresponding to such Regular Record Date, the Issuer shall instead pay the full amount of accrued and unpaid Interest
(to, but not including, such Interest Payment Date) 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 the Notes to be repurchased.


 


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


 


		(1)	if the Notes to be repurchased are in definitive form, delivery to the Paying Agent by the Holder of a duly completed written
repurchase notice (the “Fundamental Change Repurchase Notice”), as set forth in the Form of Repurchase Notice
attached as Attachment 3 to the Form of Note attached as Exhibit A hereto, or if the Notes to be repurchased are Global
Notes, in compliance with the Depositary’s procedures for surrendering interests in Global Notes, in each case on or before
the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date, subject to extensions to
comply with applicable law; and



 


		(2)	if the Notes to be repurchased are in definitive form, delivery of the 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 office of the Paying
Agent, or if the Notes to be repurchased are Global Notes, book-entry transfer of the Notes in compliance with the procedures of
the Depositary, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price
therefor.



 


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


 


		(1)	if certificated, the certificate numbers of such Notes to be delivered for repurchase;



 


		(2)	the portion of the principal amount of such Notes, which must be such that the principal amount that remains outstanding of
each Note that is not to be repurchased in full equals $1,000 or an integral multiple of $1,000 in excess thereof; and



 


		(3)	that such Notes are to be repurchased by the Issuer pursuant to the applicable provisions of the Notes and this Indenture.



 


Notwithstanding anything herein to the contrary,
any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 3.01 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 third 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 3.03.


 


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


 




    	22



     


    

 


(c)  On or before the 20th calendar day after
the occurrence of a Fundamental Change, the Issuer shall provide to all Holders of the Notes, the Trustee, the Exchange Agent and
the Paying Agent (in the case of any Paying Agent other than the Trustee) a written notice (the “Fundamental Change Issuer
Notice”) of the occurrence of such Fundamental Change and of the resulting repurchase right at the option of the Holders
arising as a result thereof. Such notice shall be sent by first class mail or overnight courier or, in the case of any Global Notes,
in accordance with the procedures of the Depositary for providing notices. Simultaneously with providing such Fundamental Change
Issuer Notice, the Issuer shall publish a notice containing this information in a newspaper of general circulation in The City
of New York or publish the information on the General Partner’s website or through such other public medium as the Issuer
may use at that time.


 


Each Fundamental Change Issuer Notice shall
state:


 


		(1)	the events causing the Fundamental Change;



 


		(2)	the date of the Fundamental Change;



 


		(3)	the last date on which a Holder of Notes may exercise the repurchase right pursuant to this Article 3;



 


		(4)	the Fundamental Change Repurchase Price;



 


		(5)	the Fundamental Change Repurchase Date;



 


		(6)	if applicable, the name and address of the Paying Agent and the Exchange Agent;



 


		(7)	if applicable, the applicable Exchange Rate and any adjustments to the applicable Exchange Rate;



 


		(8)	if applicable, that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may
be exchanged only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture;
and



 


		(9)	the procedures that Holders must follow to require the Issuer to repurchase their Notes.



 


No failure of the Issuer to give the foregoing notices and no
defect therein shall limit the repurchase rights of the Holders of Notes or affect the validity of the proceedings for the repurchase
of the Notes pursuant to this Section 3.01.


 


At the Issuer’s written request, the
Paying Agent shall give such notice in the Issuer’s name and at the Issuer’s expense; provided, however, that, in all
cases, the text of such Fundamental Change Issuer Notice shall be prepared by the Issuer and given to the Paying Agent at least
three business days prior to the date of such notification.


 


(d)  Notwithstanding the foregoing, there
shall be no repurchase of any Notes pursuant to this Section 3.01 if the principal amount of the Notes has been accelerated, and
such acceleration has not been rescinded, on or prior to the Fundamental Change Repurchase Date (except in the case of an acceleration
resulting from a default by the Issuer in the payment of the Fundamental Change Repurchase Price with respect to such Notes). The
Paying Agent will promptly return to the respective Holders thereof any Notes in definitive form held by it during the acceleration
of the Notes (except in the case of an acceleration resulting from a default by the Issuer in the payment of the Fundamental Change
Repurchase Price with respect to such Notes) and shall deem to be cancelled any instructions for book-entry transfer of the Notes
in compliance with the procedures of the Depositary, in which case, 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.


 




    	23



     


    

 


(e)  Notwithstanding the other provisions
of this Article 3, the Issuer will not be required to make an offer to repurchase the Notes upon a Fundamental Change if a third
party makes such an offer to purchase in the manner, at the times and otherwise in compliance with the requirements set forth in
this Indenture applicable to an offer to repurchase made by the Issuer and such third party purchases all Notes properly tendered
and not validly withdrawn under its offer. Any third party that intends to make such an offer to purchase the Notes shall give
prior written notice to the Trustee.


 


Section 3.02 Effect of Fundamental Change Repurchase Notice.


 


Upon receipt by the Paying Agent of the
Fundamental Change Repurchase Notice, the Holder of the Note in respect of which such Fundamental Change Repurchase Notice was
given shall (unless such Fundamental Change Repurchase Notice is withdrawn in accordance with Section 3.03) thereafter be entitled
to receive solely the Fundamental Change Repurchase Price in cash with respect to such Note (and any previously accrued and unpaid
interest on such Note). Such Fundamental Change Repurchase Price shall be paid to such Holder, subject to receipt of funds by the
Paying Agent, on the later of (x) the applicable Fundamental Change Repurchase Date (provided the conditions in Section 3.01 have
been satisfied) and (y) the time of delivery or book-entry transfer of such Note to the Paying Agent by the Holder thereof in the
manner required by Section 3.01, subject in each case to extensions to comply with applicable law.


 


Section 3.03 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 Paying Agent prior to the Close
of Business on the third Business Day immediately preceding the Fundamental Change Repurchase Date. The notice of withdrawal shall
state:


 


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



 


		(2)	if Notes have been issued in definitive form, the certificate numbers of the withdrawn Notes; and



 


		(3)	the principal amount, if any, of each Note that remains subject to the Fundamental Change Repurchase Notice, which must be
such that the principal amount not to be repurchased equals $1,000 or an integral multiple of $1,000 in excess thereof;



 


provided, however, that if the Notes are Global
Notes, the notice must comply with applicable procedures of the Depositary.


 


The Paying Agent will promptly return to
the respective Holders thereof any Notes in definitive form with respect to which a Fundamental Change Repurchase Notice has been
withdrawn in compliance with the provisions of this Section 3.03.


 


Section 3.04 Deposit of Fundamental Change Repurchase
Price.


 


Prior to 10:00 a.m., New York City time,
on the Fundamental Change Repurchase Date, the Issuer shall deposit with the Paying Agent (or if the Issuer or a Subsidiary or
an Affiliate of the Issuer is acting as the Paying Agent, shall set aside, segregate and hold in trust as provided herein) an amount
of money (in immediately available funds if deposited on such Business Day) sufficient to pay the Fundamental Change Repurchase
Price of all the Notes or portions thereof that are to be repurchased as of the Fundamental Change Repurchase Date.


 




    	24



     


    

 


(b)  If by 10:00 a.m. New York City time,
on the Fundamental Change Repurchase Date, the Paying Agent holds money sufficient to pay the Fundamental Change Repurchase Price
of the Notes for which a Fundamental Change Repurchase Notice has been tendered and not withdrawn in accordance with this Indenture
on the Fundamental Change Repurchase Date, then as of such Fundamental Change Repurchase Date, (i) such Notes will cease to be
outstanding and interest will cease to accrue thereon (whether or not book-entry transfer of the Notes has been made or the Notes
have been delivered to the Paying Agent) and (iii) all other rights of the Holders in respect thereof will terminate (other than
the right to receive the Fundamental Change Repurchase Price and, if applicable, accrued and unpaid interest upon delivery or book-entry
transfer of such Notes).


 


Section 3.05 Notes Repurchased in Whole or in Part.


 


Any certificated Note that is to be repurchased,
whether in whole or in part, shall be surrendered at the office of the Paying Agent (with, if the Issuer or the Trustee so requires
in the case of Notes in definitive form, due endorsement by, or a written instrument of transfer in form satisfactory to the Issuer
and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Issuer
shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, a new Note or
Notes, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for,
the portion of the principal amount of the Note so surrendered that is not purchased.


 


Section 3.06 Covenant To Comply with Applicable Laws upon
Repurchase of Notes. 


 


In connection with any offer to repurchase
Notes under Section 3.01, the Issuer shall, in each case if required by law, (i) comply with Rule 13e-4, Rule 14e-1 and any other
tender offer rules under the Exchange Act that may then be applicable, (ii) file a Schedule TO or any other required schedule under
the Exchange Act and (iii) otherwise comply with all federal and state securities laws applicable to the Issuer in connection with
such repurchase offer, in each case, so as to permit the rights and obligations under Article 3 to be exercised in the time and
in the manner specified in Article 3.


 


Section 3.07 Repayment to the Issuer.


 


To the extent that the aggregate amount
of cash deposited by the Issuer pursuant to Section 3.04 exceeds the aggregate Fundamental Change Repurchase Price of the Notes
or portions thereof that the Issuer is obligated to repurchase as of the Fundamental Change Repurchase Date, then, following the
Fundamental Change Repurchase Date, the Paying Agent shall promptly return any such excess to the Issuer.


 


ARTICLE 4

PARTICULAR COVENANTS OF THE ISSUER AND THE GENERAL PARTNER


 


Section 4.01. Payment of Principal and Interest.


 


The Issuer covenants and agrees that it
will duly and punctually pay or cause to be paid when due the principal of (including the repurchase price upon repurchase pursuant
to Article 3) and Interest on each of the Notes at the places, at the respective times and in the manner provided herein and in
the Notes.


 




    	25



     


    

 


Section 4.02. Maintenance of Office or Agency.


 


The Issuer will maintain an office or agency
where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or for exchange or
repurchase and where notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be served. As of
the date of this Indenture, such office shall be the Corporate Trust Office and, at any other time, at such other address as the
Trustee may designate from time to time by notice to the Issuer. The Issuer will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency not designated or appointed by the Trustee. If at any time the
Issuer 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, and the Issuer hereby
appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.


 


The Issuer may also from time to time designate
co-registrars and one or more offices or agencies where the Notes may be presented or surrendered for any or all such purposes
and may from time to time rescind such designations, provided, however that no such designation or rescission shall in any
manner relieve the Issuer of its obligation to maintain an office or agency for such purposes . The Issuer 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.


 


The Issuer hereby initially designates the
Trustee as Paying Agent, Note Registrar, Custodian and Exchange Agent and the Corporate Trust Office shall be considered as one
such office or agency of the Issuer for each of the aforesaid purposes.


 


So long as the Trustee is the Note Registrar,
the Trustee agrees, at the expense of the Issuer, to deliver, or cause to be delivered, the notices set forth in Section 7.08(f),
if applicable, in accordance with the procedures of the Depositary. If co-registrars have been appointed in accordance with this
Section, the Trustee shall mail such notices only to the Issuer and the Holders of Notes it can identify from its records. 


 


Section 4.03. Appointments to Fill Vacancies in Trustee’s
Office.


 


The Issuer, whenever necessary to avoid
or fill a vacancy in the office of Trustee, will appoint, upon the terms and conditions and otherwise as provided in Section 7.08,
a Trustee, so that there shall at all times be a Trustee hereunder.


 


Section 4.04. Provisions as to Paying Agent.


 


(a)  If the Issuer shall appoint a Paying
Agent other than the Trustee, or if the Trustee shall appoint such a Paying Agent, the Issuer will cause such Paying Agent to execute
and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section
4.04:


 


		(1)	that it will hold all sums held by it as such agent for the payment of the principal of or Interest on the Notes (whether such
sums have been paid to it by the Issuer or by any other obligor on the Notes) in trust for the benefit of the Holders of the Notes;



 


		(2)	that it will give the Trustee notice of any failure by the Issuer (or by any other obligor on the Notes) to make any payment
of the principal of or Interest on the Notes when the same shall be due and payable; and



 


		(3)	that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee
all sums so held in trust.



 




    	26



     


    

 


The Issuer shall, on or before each due
date of the principal of or Interest on the Notes, deposit with the Paying Agent a sum (in funds which are immediately available
on the due date for such payment) sufficient to pay such principal or Interest and (unless such Paying Agent is the Trustee) the
Issuer will promptly notify the Trustee of any failure to take such action; provided that if such deposit is made on the
due date, such deposit shall be received by the Paying Agent by no later than 11:00 a.m. New York City time, on such date.


 


(b)  If the Issuer shall act as its own Paying
Agent, it will, on or before each due date of the principal of or Interest on the Notes, set aside, segregate and hold in trust
for the benefit of the Holders of the Notes a sum sufficient to pay such principal and Interest so becoming due and will promptly
notify the Trustee of any failure to take such action and of any failure by the Issuer (or any other obligor under the Notes) to
make any payment of the principal of or Interest on the Notes when the same shall become due and payable.


 


(c)  Anything in this Section 4.04 to the
contrary notwithstanding, the Issuer may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture,
or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by the Issuer or any Paying Agent hereunder
as required by this Section 4.04, such sums to be held by the Trustee upon the trusts herein contained and upon such payment by
the Issuer or any Paying Agent to the Trustee, the Issuer or such Paying Agent shall be released from all further liability with
respect to such sums.


 


(d)  Anything in this Section 4.04 to the
contrary notwithstanding, the agreement to hold sums in trust as provided in this Section 4.04 is subject to Section 11.02.


 


The Trustee shall not be responsible for,
and shall have no liability for, the actions of any other Paying Agents (including the Issuer if acting as its own Paying Agent)
and shall have no control of any funds held by such other Paying Agents.


 


Section 4.05. Existence.


 


Subject to Article 10, each of the Issuer
and the General Partner will do or cause to be done all things necessary to preserve and keep in full force and effect its existence
and all material rights and material franchises; provided, however, that neither the Issuer nor the General Partner
shall be required to preserve any such right or franchise if the Board of Directors shall determine that the preservation thereof
is no longer desirable in the conduct of the business of the Issuer or the General Partner, as applicable.


 


Section 4.06. Rule 144A Information Requirement; Annual
Reports; Additional Interest. 


 


(a)  At any time that the General Partner
is not subject to Section 13 or 15(d) of the Exchange Act, the Issuer shall, so long as any of the Notes shall, at such time, constitute
“restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, upon written request, provide
to any Holder, beneficial owner or prospective purchaser of such Notes, the information required to be delivered pursuant to Rule
144A(d)(4) under the Securities Act to facilitate the resale of such Notes pursuant to Rule 144A.


 


(b)  The Issuer shall file with the Trustee,
within 15 days after the same are required to be filed with the Commission, copies of the quarterly and annual reports and of the
information, documents and other reports, if any, that the General Partner is required to file with the Commission pursuant to
Section 13 or 15(d) of the Exchange Act (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act). Any
such report, information or document that the General Partner files with the Commission through the Commission’s EDGAR system
(or any successor thereto) will be deemed to be filed with the Trustee for purposes of this Section 4.06(b) at the time of
such filing through the EDGAR system (or such successor thereto). The Trustee shall have no liability or responsibility for the
filing, timeliness or content of such reports.


 




    	27



     


    

 


(c)   Delivery of any such reports, information
and documents described in subsection (b) above to the Trustee shall be 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 Issuer’s compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).


 


(d)  If, at any time during the six-month
period beginning on, and including, the date that is six months after the last date of original issuance of the Notes, the General
Partner fails to timely file any document or report that it is required to file with the Commission pursuant to Section 13 or 15(d)
of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form
8-K), or the Notes or any shares of Common Stock issuable upon exchange of the Notes are not otherwise freely tradable pursuant
to Rule 144 by Holders other than the Issuer’s Affiliates or Holders that were the Issuer’s Affiliates at any time
during the three months immediately preceding (as a result of restrictions pursuant to U.S. securities laws or the terms of this
Indenture or the Notes), the Issuer shall pay Additional Interest on the Notes. Such Additional Interest shall accrue on the Notes
at the rate of 0.50% per annum of the principal amount of the Notes outstanding for each day during such period for which the General
Partner’s failure to file has occurred and is continuing or the Notes or any shares of Common Stock issuable upon exchange
of the Notes are not otherwise freely tradable as described above by Holders other than the Issuer’s Affiliates (or Holders
that were the Issuer’s Affiliates at any time during the three months immediately preceding). As used in this Section 4.06(d),
documents or reports that the General Partner is required to “file” with the Commission pursuant to Section 13 or 15(d)
of the Exchange Act does not include documents or reports that the General Partner furnishes to the Commission pursuant to Section
13 or 15(d) of the Exchange Act.


 


(e)  If, and for so long as, the Restricted
Notes Legend on the Notes has not been removed, the Notes are assigned a restricted CUSIP number or the Notes and any shares of
Common Stock issuable upon exchange of the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the
Issuer’s Affiliates or Holders that were the Issuer’s Affiliates at any time during the three months immediately preceding
(without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes) as of the 365th day after the
last date of original issuance of the Notes, the Issuer shall pay Additional Interest on the Notes at a rate equal to 0.50% per
annum of the principal amount of Notes outstanding until the Restricted Notes Legend on the Notes has been removed in accordance
with Section 2.05(c), the Notes are assigned an unrestricted CUSIP number and the Notes and any shares of Common Stock issuable
upon exchange of the Notes are freely tradable as described above by Holders other than the Issuer’s Affiliates (or Holders
that were the Issuer’s Affiliates at any time during the three months immediately preceding) without restrictions pursuant
to U.S. securities laws or the terms of this Indenture or the Notes. The Restricted Notes Legend on the Notes shall be deemed removed
pursuant to the terms of this Indenture as provided in Section 2.05(c), and, at such time, the Notes will, pursuant to, and subject
to the provisions of, such Section, be deemed assigned an unrestricted CUSIP number. However, for the avoidance of doubt, the Global
Notes will continue to bear Additional Interest pursuant to this paragraph until such time as they are identified by an unrestricted
CUSIP number in the facilities of the Depositary therefor, as a result of completion of such Depositary’s mandatory exchange
process or otherwise.


 


(f)  Additional Interest will be payable
in arrears on each Interest Payment Date following accrual in the same manner as regular Interest on the Notes.


 


(g)  The Additional Interest that is payable
in accordance with Section 4.06(d) or Section 4.06(e) shall be in addition to, and not in lieu of, any Additional Interest that
may accrue at the Issuer’s election as the sole remedy relating to the failure to comply with the Issuer’s reporting
obligations pursuant to Section 6.09.


 




    	28



     


    

 


(h)  If Additional Interest is payable by
the Issuer pursuant to Section 4.06(d) or Section 4.06(e), the Issuer shall deliver to the Trustee (copied to the Paying Agent)
an Officers’ Certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date
on which such Additional Interest is payable. Unless and until a Responsible Officer of the Trustee and the Paying Agent receives
at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable.
In the case of any Notes in definitive form, if the Issuer has paid Additional Interest directly to the Persons entitled to it,
the Issuer shall deliver to the Trustee and the Paying Agent an Officers’ Certificate setting forth the particulars of such
payment.


 


(i)  Notwithstanding the foregoing, the Issuer
will not be required to pay Additional Interest with respect to any failure to remove the Restricted Notes Legend or assign an
unrestricted CUSIP number on the Notes or if the Notes and any shares of Common Stock issuable upon exchange of the Notes are not
freely tradable, for any date on which the following four conditions are satisfied: (1) the General Partner has filed a shelf registration
statement for the resale of the Notes and any shares of Common Stock issuable upon exchange of the Notes, as applicable, (2) such
shelf registration statement is effective and usable by Holders identified therein as selling security holders for the resale of
the Notes and any shares of Common Stock issued upon exchange of the Notes, as applicable, (3) the Holders may sell their Notes
and any shares of Common Stock issued upon exchange of the Notes, as applicable, under such shelf registration statement on terms
customary for the resale of convertible or exchangeable securities offered in reliance on Rule 144A and (4) the Notes and/or shares
of Common Stock sold pursuant to such shelf registration statement become freely tradable as a result of such sale.


 


Section 4.07. Stay, Extension and Usury Laws.


 


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


 


Section 4.08. Compliance Certificate.


 


The Issuer will deliver to the Trustee,
within 120 days after the end of each fiscal year, an Officers’ Certificate stating whether or not to the knowledge of the
signers thereof, the Issuer or the General Partner is in default in the performance and observance of any of the terms, provisions
and conditions under this Indenture (without regard to any period of grace or requirement of notice provided under the Indenture)
and, if the Issuer or the General Partner is in default, specifying all such defaults and the nature and the status thereof of
which they may have knowledge. The Issuer will promptly notify the Trustee if the Issuer changes its fiscal year end to a date
other than December 31. For purposes of this Section 4.08, such compliance shall be determined without regard to any period of
grace or requirement of notice under this Indenture.


 


The Issuer will deliver to the Trustee,
as soon as possible, and in any event within 30 days after the Issuer becomes aware of the occurrence of any Default or Event of
Default, an Officers’ Certificate specifying with particularity such Defaults or Event of Defaults, as applicable, their
status and what action the Issuer has taken, is taking or proposes to take with respect thereto.


 


Any notice required to be given under this
Section 4.08 shall be delivered to a Responsible Officer of the Trustee at its Corporate Trust Office.

Section 4.09. Reservation of Shares, Shares to Be Fully
Paid; Compliance with Governmental Requirements; Listing of Common Stock.


 


The General Partner shall provide, free
from preemptive rights, out of its authorized but unissued shares, sufficient shares of Common Stock to provide for the exchange
of the Notes as required by this Indenture from time to time as such Notes are presented for exchange.


 


The General Partner covenants that all shares
of Common Stock which may be issued upon exchange of Notes will upon issue be fully paid and non-assessable by the General Partner
and free from all taxes, liens and charges with respect to the issue thereof.


 


The General Partner covenants that, if any
shares of Common Stock to be provided for the purpose of exchange 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 exchange, the General Partner
shall, as expeditiously as possible secure such registration or approval, as the case may be.


 


The General Partner further covenants that,
if at any time the Common Stock shall be listed on the NYSE or any other national or regional securities exchange or automated
quotation system, the General Partner will, if permitted by the rules of such exchange or automated quotation system, list and
keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, all the Common Stock
issuable upon exchange of the Notes; provided that if the rules of such exchange or automated quotation system permit the
General Partner to defer the listing of such the Common Stock until the first exchange of the Notes in accordance with the provisions
of this Indenture, the General Partner covenants to list such Common Stock issuable upon exchange of the Notes in accordance with
the requirements of such exchange or automated quotation system at such time.

EVENTS OF DEFAULT; REMEDIES


 


Section 6.01. Events of Default.


 


(a) Events of Default. In case any
one or more of the following (each, an “Event of Default”) (whatever the reason for such Event of Default and
whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of
any court or any order, rule or regulation of any administrative or governmental body) shall have occurred and be continuing:


 


		(1)	default in the payment of any interest upon any Note when it becomes due and payable, and continuance of such default for a
period of 30 days;



 


		(2)	default in the payment of the principal of any Note (including the Fundamental Change Repurchase Price) when due and payable
on the Maturity Date, upon required repurchase, upon declaration of acceleration or otherwise;



 


		(3)	failure by the Issuer or the General Partner to comply with the obligation to exchange the Notes for cash, shares of Common
Stock or a combination of cash and shares of Common Stock, as the case may be, in accordance with this Indenture upon exercise
of a Holder’s exchange right, which failure continues for five Business Days;



 


		(4)	failure by the Issuer to comply with its obligations under Article 10;



 


		(5)	failure by the Issuer to issue a Fundamental Change Issuer Notice in accordance with Section 3.01(c) when due;



 


		(6)	failure by the Issuer for 60 days after written notice from the Trustee or the Holders of at least 25% in aggregate principal
amount of the Notes then outstanding (a copy of which notice, if given by Holders, must also be given to the Trustee) has been
received by the Issuer to comply with any of its other agreements contained in the Notes or this Indenture (other than a covenant
or warranty a default in whose performance or whose breach is elsewhere in this section specifically provided for or which does
not apply to the Notes), which notice shall state that it is a “Notice of Default” under this Indenture;



 


		(7)	default following the failure by the Issuer to pay beyond any applicable grace period, or resulting in the acceleration of,
indebtedness of the Issuer or any of its Subsidiaries where the aggregate principal amount with respect to which the default has
occurred is greater than $10 million (or its foreign currency equivalent at such time);



 


		(8)	the Issuer, the General Partner or any Significant Subsidiary shall commence a voluntary case or other proceeding seeking liquidation,
reorganization or other relief with respect to the Issuer, the General Partner 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 Issuer, the General Partner 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



 


		(9)	an involuntary case or other proceeding shall be commenced against the Issuer, the General Partner, or any 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 Issuer, the General Partner 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 days.



 




    	31



     


    

 


(b)  If one or more Events of Default shall
have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary
or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of
any administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section
6.01(a)(8) or Section 6.01(a)(9) with respect to the Issuer, the General Partner or any Significant Subsidiary), unless the principal
of all of the Notes shall have already become due and payable, 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 Issuer (and to the Trustee if given by Holders), may declare
100% of the principal of, and accrued and unpaid interest, if any, on, all then outstanding Notes to be due and payable immediately,
and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything contained
in this Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Section 6.01(a)(8) or Section
6.01(a)(9) with respect to the Issuer, the General Partner or any Significant Subsidiary occurs and is continuing, 100% of the
principal of, and accrued and unpaid interest, if any, on, all then outstanding Notes shall become and shall automatically be immediately
due and payable.


 


(c)  The Holders of a majority in aggregate
principal amount of the Notes then outstanding on behalf of the Holders of all of the Notes then outstanding, by written notice
to the Issuer and to the Trustee, may waive (including, by way of consents obtained in connection with a repurchase of, or tender
or exchange offer for, the Notes) all past Defaults or Events of Default (except with respect to nonpayment of principal or Interest,
the failure to deliver the consideration due upon exchange or any other provision that requires the consent of each affected Holder
to amend) and rescind any acceleration with respect to the Notes and its consequences, subject in all respects to Section 6.07,
if (i) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) 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.


 


(b)  In case the Trustee shall have proceeded
to enforce any right under this 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 Issuer, the Holders of Notes, and the Trustee shall be restored respectively to their several positions and rights hereunder,
and all rights, remedies and powers of the Issuer, the Holders of Notes, and the Trustee shall continue as though no such proceeding
had been taken. Notwithstanding the foregoing, the Trustee shall retain all rights under this Indenture to be indemnified for expenses
incurred related to such proceeding.


 


Section 6.02. Payments of Notes on Default; Suit Therefor.



 


The Issuer covenants that in the case of
an Event of Default pursuant to Section 6.01(a)(1) or 6.01(a)(2), upon demand of the Trustee, the Issuer will 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
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 at the rate borne by the Notes from the required
payment date and, (ii) in addition thereto, any amounts due the Trustee under this Indenture, including, but not limited to, Section
7.06. Until such demand by the Trustee, the Issuer may pay the principal of and Interest on the Notes to the registered Holders,
whether or not the Notes are overdue.


 




    	32



     


    






In case the Issuer shall fail forthwith to pay
such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered
to institute any 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 Issuer
or any other obligor on the Notes and collect in the manner provided by law out of the property of the Issuer or any other obligor
on the Notes wherever situated the monies adjudged or decreed to be payable.


 


In case of the pendency of any receivership,
insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative
to the General Partner, the Issuer or any other obligor upon the Notes or the property of the General Partner, the Issuer or of
such other obligor or their creditors, 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 on the Issuer
for the payment of overdue principal (including the repurchase price upon repurchase pursuant to Article 3)) shall be entitled
and empowered, by intervention in such proceeding or otherwise: (i) to file and prove a claim for the whole amount of principal
(including the repurchase price upon repurchase pursuant to Article 3) and Interest owing and unpaid in respect of the Notes 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 of Notes allowed in such judicial proceeding, and (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 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 Notes, 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 7.06. 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 Note any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof,
or to authorize the Trustee to vote in respect of the claim of any Holder of Notes in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders of Notes, vote for the election of a trustee in bankruptcy or similar official and
may be a member of the creditors’ committee.


 


All rights of action and of asserting claims
under this 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 this 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.


 


Section 6.03. Application of Monies Collected by Trustee.


 


Any monies collected by the Trustee pursuant
to this Article 6 with respect to the Notes shall be applied, in the following order, 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:


 


First,
to the payment of all amounts due the Trustee, including its agents and counsel, under ‎Section
7.06;


 


Second, in case the principal
of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on, and any cash due upon exchange
of, the Notes in default in the order of the date due of the payments of such interest and cash due upon exchange, 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, such payments to be made ratably to the Persons entitled thereto;


 




    	33



     


    

 


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,
if applicable, the payment of the Fundamental Change Repurchase Price and any cash due upon exchange) then owing and unpaid upon
the Notes for principal and interest, if any, with interest on the overdue principal and, to the extent that such interest has
been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time, 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
(including, if applicable, the Fundamental Change Repurchase Price and any cash due upon exchange) and 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 (including, if applicable, the Fundamental
Change Repurchase Price and any cash due upon exchange) and accrued and unpaid interest; and


 


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


 


Section 6.04. Proceedings by Noteholders.


 


Except to enforce the right to receive payment
of principal (including, if applicable, the Fundamental Change Repurchase Price) or interest when due, or the right to receive
payment or delivery of the consideration due upon exchange, no Holder of any Note shall have any right by virtue of or by availing
of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect
to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other
remedy hereunder, unless:


 


		(1)	such Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof,
as herein provided;



 


		(2)	Holders of at least 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the
Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder;



 


		(3)	such Holders shall have offered to the Trustee such security and/or indemnity satisfactory to the Trustee against any losses,
liabilities or expense to be incurred therein or thereby (including fees of the Trustee’s legal counsel);



 


		(4)	the Trustee for 60 days after its receipt of such notice, request and offer of such security and/or indemnity, shall have refused
to institute any such action, suit or proceeding; and



 


		(5)	no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee
by the Holders of a majority of the aggregate principal amount of the Notes then outstanding in accordance with Section 6.07,



 


it being understood and intended, and being expressly covenanted
by the taker and Holder of every Note with every other taker and Holder and the Trustee that no one or more 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 Holder, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce
any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders
(except as otherwise provided herein). For the protection and enforcement of this ‎Section 6.04, each and every Holder and
the Trustee shall be entitled to such relief as can be given either at law or in equity.


 




    	34



     


    

 


Notwithstanding any other provision of this
Indenture and any provision of any Note, each Holder shall have the right, which is absolute and unconditional, to receive payment
or delivery, as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (y)
accrued and unpaid interest, if any, on, and (z) the consideration due upon exchange of, such Note, on or after the respective
due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the enforcement of any such payment
or delivery, as the case may be, and such rights shall not be impaired 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 exchange as provided herein.


 


Section 6.05. Proceedings by Trustee.


 


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


 


Section 6.06. Remedies Cumulative and Continuing. 


 


All powers and remedies given by this Article 6
to the Trustee or to the Noteholders 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 this 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 6.04, every power and remedy given by
this Article 6 or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be
deemed expedient, by the Trustee or by the Noteholders.


 


Section 6.07. Direction of Proceedings and Waiver of Defaults
by Majority of Noteholders.


 


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 exercising any trust or power conferred on the Trustee; provided that
(a) such Holders shall have offered to the Trustee such security and/or indemnity satisfactory to the Trustee against any losses,
liabilities or expenses to be incurred therein or thereby (including fees of the Trustee’s legal counsel) (b) such direction
shall not be in conflict with any rule of law or with this Indenture, (c) the Trustee may take any other action deemed proper by
the Trustee which is not inconsistent with such direction, and (d) the Trustee need not take any action which might involve it
in personal liability, subject it to reputational harm, or be unduly prejudicial to the Holders of Notes not joining therein, it
being understood that (subject to Section 7.02) the Trustee shall have no duty to ascertain whether or not such actions or forbearance
are unduly prejudicial to such Holders.


 




    	35



     


    

 


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 the principal of or Interest on the Notes,
(ii) a failure by the Issuer to exchange any Notes as required by this Indenture, (iii) a default in the payment of the repurchase
price on the Fundamental Change Repurchase Date pursuant to Article 3 or (iv) a default in respect of a covenant or provisions
hereof, which under Article 9 cannot be modified or amended without the consent of the Holders of all Notes then outstanding
or each Note affected thereby.


 


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 6.08. Undertaking to Pay Costs.


 


All parties to this 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 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 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 6.08 (to the extent permitted by law) shall not apply to any suit instituted
by the Trustee, to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than ten percent
in principal amount of the Notes at the time outstanding determined in accordance with Section 8.04, or to any suit instituted
by any Noteholder for the enforcement of the payment of the principal of (including the repurchase price upon repurchase pursuant
to Article 3), or Interest on any Note on or after the due date expressed in such Note or to any suit for the enforcement of the
right to exchange any Note in accordance with the provisions of Article 13.


 


Section 6.09. Additional Interest.


 


Notwithstanding anything in this Indenture or
in the Notes to the contrary, to the extent the Issuer elects, the sole remedy for an Event of Default relating to the Issuer’s
failure to comply with its obligations as set forth in Section 4.06(b) shall, for the first 180 days after the occurrence of such
an Event of Default, consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to 0.50% per
annum of the principal amount of the Notes outstanding for each day during the 180-day period beginning on, and including, the
day on which such Event of Default occurs and during which such event is continuing (and neither waived nor cured). Additional
Interest payable pursuant to this Section 6.09 shall be in addition to, not in lieu of, any Additional Interest payable pursuant
to Section 4.06(d) or Section 4.06(e). If the Issuer so elects, 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 181st day after such Event of Default (if the Event of Default
relating to reporting obligations is not cured or waived prior to such 181st day), the Notes shall be immediately subject to acceleration
as provided in Section 6.01. The provisions of this paragraph will not affect the rights of Holders of Notes in the event of the
occurrence of any other Event of Default. In the event the Issuer does not elect to pay Additional Interest following an Event
of Default in accordance with this Section 6.09 or the Issuer elected to make such payment but does not pay the Additional Interest
when due, the Notes shall be immediately subject to acceleration as provided in Section 6.01.


 


In order to elect to pay Additional Interest
as the sole remedy during the first 180 days after the occurrence of any Event of Default described in the immediately preceding
paragraph, the Issuer must notify all Holders of the Notes of such election, and must deliver to the Trustee and the Paying Agent
an Officers’ Certificate (consistent with ‎Section 4.06(h)) prior to the beginning of such 180-day period. Upon the failure
to timely give such notice, the Notes shall be immediately subject to acceleration as provided in ‎Section 6.01.

ARTICLE 7

THE TRUSTEE


 


Section 7.01. Notice of Defaults.


 


Within ninety (90) calendar days after a Responsible
Officer of the Trustee has actual knowledge of the occurrence of any Default hereunder, the Trustee shall transmit a notice of
such Default to the Holders of Notes in accordance with the procedures of the Depositary, unless such Default shall have been cured
or waived pursuant to the terms of Section 6.07 hereof; provided, however, that, except in the case of a default in the
payment of the principal of (including the Fundamental Change Repurchase Price, if applicable) or Interest on any Note or in the
delivery of the consideration due upon exchange, the Trustee may withhold and shall be protected in withholding such notice if
and so long as the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders of the
Notes.


 


Section 7.02. Certain Rights of Trustee.


 


Except as otherwise provided in Section 7.12:


 


		(1)	the Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, Officers’
Certificate, certificate, statement, instrument, Opinion of Counsel, opinion, report, notice, request, direction, consent, order,
bond, debenture, note, coupon or other paper or document believed by it to be genuine and to have been signed or presented by the
proper party or parties. If presented with a non-conforming certificate or opinion, the Trustee may request the delivering party
to re-issue the certificate or opinion in the manner required by this Indenture before taking any action;



 


		(2)	any request or direction of the Issuer mentioned herein shall be sufficiently evidenced by an Issuer Request or Issuer Order
(other than delivery of any Note to the Trustee for authentication and delivery pursuant to Sections 2.01 and 2.04, which shall
be sufficiently evidenced as provided therein) and any resolution of the Board of Directors may be sufficiently evidenced to the
Trustee by a copy of a Board Resolution certified by the Secretary or Assistant Secretary of the General Partner;



 


		(3)	the Trustee may consult with counsel of its selection, and the written advice of such counsel or any Opinion of Counsel shall
be full and complete authorization and protection in respect of any action taken, suffered or omitted by the Trustee hereunder
in good faith and in reliance thereon;



 


		(4)	the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request
or direction of any of the Holders of Notes pursuant to this Indenture, unless such Holders shall have offered to the Trustee security
or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance
with such request or direction, provided, however, that the Trustee shall be under no obligation to take any action
it believes to be unlawful, contrary to the terms of this Indenture, or that could subject the Trustee to reputational harm;



 




    	37



     


    

 


		(5)	the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon or other paper or document,
but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit,
and if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine, either personally
or by agent or attorney, the books, records and premises of the Issuer relevant to the facts or matters that are the subject of
its inquiry, and the Trustee shall incur no liability of any kind by reason of such inquiry or investigation. Holders of not less
than a majority in aggregate principal amount of the outstanding Notes may request the Trustee, in its discretion, to undertake
such further inquiry or investigation, provided that payment of the costs, expenses, or liabilities likely to be incurred
in the making of such further inquiry or investigation within a reasonable time shall be reasonably assured to the Trustee by the
security afforded to it by the terms of this Indenture. The Trustee may require indemnity satisfactory to it against such expenses
or liabilities as a condition to proceeding with such further inquiry or investigation, and the reasonable expenses of every such
examination shall be paid by the Holders or, if paid by the Trustee, shall be repaid by the Holders upon demand;



 


		(6)	the Trustee may execute any of its trusts or powers hereunder, or perform any duties reserved to it hereunder, either directly
or by or through one or more agents, affiliates, custodians, nominees, or attorneys, and the Trustee shall not be responsible or
have any liability for any misconduct or negligence on the part of any agent, affiliate, custodian, nominee, or attorney by it
hereunder appointed with due care;



 


		(7)	the Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and reasonably believed by it
to be authorized or within the discretion conferred upon it by this Indenture;



 


		(8)	if any party fails to deliver a notice relating to an event the fact of which, pursuant to this Indenture, requires notice
to be sent to the Trustee, the Trustee (to the extent that a Responsible Officer of the Trustee does not have actual knowledge
of the existence of such event or fact ) may conclusively rely on its failure to receive such notice as reason to act as if no
such event occurred;



 


		(9)	the Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder;



 


		(10)	the permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as duties;



 


		(11)	the Trustee shall not be charged with knowledge of any Default or Event of Default with respect to the Notes, unless either
(1) a Responsible Officer shall have actual knowledge of such Default or Event of Default, or (2) unless specifically notified
in writing of such event by the Issuer or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding;
as used herein, the term “actual knowledge” means the actual fact or statement of knowing, without any duty
to make any investigation with regard thereto;



 


		(12)	the Trustee may request that the Issuer deliver a certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture; and



 


		(13)	the Trustee may apply to the Issuer for written instructions, and any such application (other than with regard to any action
proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of Notes under the Indenture)
may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture
and the date on or after which such action shall be taken or such omission may be effected. In the absence of gross negligence
or willful misconduct on the part of the Trustee, the Trustee shall not be liable to the Issuer for any action taken by, or omission
of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which
date shall not be less than three (3) Business Days after the date on which any officer that the Issuer has designated to the Trustee
as the recipient of such application actually receives such application, unless such officer shall have consented in writing to
any earlier date), unless, prior to taking any action (or the effective date in the case of any omission), the Trustee shall have
received written instructions from the Issuer in accordance with this Indenture in response to such application specifying the
action to be taken or omitted.



 




    	38



     


    

 


In no event shall the Trustee be liable for
any consequential loss or damage of any kind whatsoever (including, but not limited to, lost profits), even if the Trustee has
been advised of the likelihood of such loss or damage and regardless of the form of action, other than any such loss or damage
caused by the Trustee’s gross negligence or willful misconduct.


 


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 grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. 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. The
rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified,
are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, affiliate, custodian
and other Person employed by the Trustee in its various capacities to act hereunder.


 


Section 7.03. Not Responsible for Recitals or Issuance of
Notes.


 


The recitals contained herein and in the Notes,
except the Trustee’s certificate of authentication, shall be taken as the statements of the Issuer, 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 Notes except that the Trustee represents that it is duly authorized to execute and deliver
this Indenture, authenticate the Notes and perform its obligations hereunder. Neither the Trustee nor any authenticating agent
shall be accountable for the use or application by the Issuer of Notes or the proceeds thereof.


 


Section 7.04. May Hold Notes and Common Stock.


 


The Trustee, any Paying Agent, Exchange Agent,
Note Registrar, authenticating agent or any other agent of the Issuer, in its individual or any other capacity, may become the
owner or pledgee of Notes or Common Stock and may otherwise deal with the Issuer and the General Partner with the same rights it
would have if it were not Trustee, Paying Agent, Exchange Agent, Note Registrar, Custodian, authenticating agent or such other
agent.


 


Section 7.05. 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 not be liable for interest on any
money received by it hereunder except as otherwise agreed with the Issuer.


 




    	39



     


    

 


Section 7.06. Compensation and Reimbursement.


 


The Issuer agrees:


 


		(1)	to pay to the Trustee from time to time, and the Trustee shall be entitled to, compensation for all services rendered by it
hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express
trust);



 


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



 


		(3)	to indemnify each of the Trustee and any predecessor Trustee and their respective officers, directors, employees and agents
(each, an “Indemnified Person”) for, and to hold each such Indemnified Person harmless against, any loss, liability,
or expense incurred without gross negligence or willful misconduct on the part of such Indemnified Person, arising out of or in
connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending
itself against, or investigating any claim or liability in connection with, the exercise or performance of any of its powers or
duties hereunder.



 


When the Trustee incurs expenses or renders
services in connection with an Event of Default specified in Sections 6.01(a)(8) or 6.01(a)(9), the Trustee’s expenses (including
the charges and expenses of its counsel) and compensation for its services are intended to constitute expenses of administration
under any applicable Federal or state bankruptcy, insolvency, or other similar law.


 


The obligations of the Issuer under this Section
7.06 to compensate or indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements, and advances shall
be secured by a senior lien to which the Notes are hereby made subordinate on all property and funds held or collected by the Trustee,
except, subject to the effect of Section 6.03, funds held in trust for the benefit of Holders of Notes. The obligations of the
Issuer under this Section 7.06 shall not be subordinate to any other liability or indebtedness of the Issuer. The provisions of
this Section 7.06 shall survive the discharge or termination of this Indenture and the earlier resignation or removal of the Trustee,
and the indemnification provided in this Section 7.06 shall extend to the affiliates, officers, directors, agents and employees
of the Trustee.


 


Section 7.07. Corporate Trustee Required; Eligibility; Conflicting
Interests.


 


There shall at all times be a Trustee hereunder
which shall be a Person that is eligible pursuant to the Trust Indenture Act (as if the Trust Indenture Act were applicable hereto)
with a combined capital and surplus of at least the minimum amount required by the Trust Indenture Act. If such Person 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 7.07, the combined capital and surplus of such Person
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 7.07, it shall resign immediately
in the manner and with the effect hereinafter specified in this Article. Neither the Issuer nor any Person directly or indirectly
controlling, controlled by, or under common control with the Issuer shall serve as Trustee.


 




    	40



     


    

 


Section 7.08. 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 7.09.


 


(b) The Trustee may resign at any time by giving
written notice thereof to the Issuer and the Holders of Notes. Upon receiving such notice of resignation, the Issuer shall promptly
appoint a successor trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the resigning
Trustee and one copy to the successor trustee. If an instrument of acceptance by a successor Trustee shall not have been delivered
to the resigning Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction, at the expense of the Issuer, for the appointment of a successor trustee. Such court may thereupon,
after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.


 


(c) The Trustee may be removed at any time by
action of the Holders of a majority in principal amount of the outstanding Notes delivered to the Trustee and to the Issuer.


 


(d) If at any time:


 


		(1)	the Trustee shall cease to be eligible under Section 7.07 of this Indenture and shall fail to resign after written request
therefor by the Issuer or Holders of Notes in the manner required by Section 7.08(c); or



 


		(2)	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 either case, (A) the Issuer by or pursuant to a Board Resolution
may remove the Trustee and appoint a successor Trustee by written instrument, in duplicate, one copy of which instrument shall
be delivered to the resigning Trustee and one copy to the successor trustee, or (B) any Holder of a Note who has been a bona fide
Holder of a Note for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor Trustee or Trustees. Such court may thereupon, after
such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.


 


(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, the Issuer, by or pursuant to
a Board Resolution, shall promptly appoint a successor Trustee or trustees. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a different successor Trustee shall be appointed by action of the Holders of
a majority in principal amount of the outstanding Notes delivered to the Issuer and the retiring Trustee, the successor Trustee
appointed by the Holders of Notes shall, forthwith upon its acceptance of such appointment, become the successor Trustee and to
that extent supersede the successor trustee appointed by the Issuer. If no successor Trustee shall have been so appointed by the
Issuer or the Holders of Notes and accepted appointment in the manner hereinafter provided, any Holder of a Note who has been a
bona fide Holder of a Note 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.


 


(f) The Issuer shall give notice of each resignation
and each removal of the Trustee and each appointment of a successor Trustee by delivering or causing to be delivered such notice
to the Holders of Notes as they appear on the Note Register. Each notice shall include the name of the successor Trustee and the
address of its Corporate Trust Office.


 




    	41



     


    

 


Section 7.09. Acceptance of Appointment By Successor Trustee.


 


(a) In case of the appointment hereunder of
a successor Trustee, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Issuer 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 Issuer or the successor Trustee, such retiring Trustee
shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers
and trusts of the retiring Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder, subject nevertheless to its claim, if any, provided for in Section 7.06.


 


(b) In case of the appointment hereunder of
a successor Trustee, the Issuer, the retiring Trustee and each successor Trustee shall execute and deliver an indenture supplemental
hereto, pursuant to Article Ten hereof, wherein each successor Trustee shall accept such appointment and which (i) 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 to which the appointment of such successor Trustee relates, (ii) if the retiring
Trustee is not retiring all Notes, 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 as to which the retiring Trustee is not retiring shall continue to
be vested in the retiring Trustee, and (iii) 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 to which the appointment of such successor
Trustee relates; but, on request of the Issuer 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 to which the appointment of such
successor Trustee relates.


 


(c) Upon request of any such successor Trustee,
the Issuer 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 7.09, 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 7.


 


Section 7.10. Merger, Conversion, Consolidation or Succession
to Business.


 


Any legal entity into which the Trustee may
be merged or converted or with which it may be consolidated, or any legal entity resulting from any merger, conversion or consolidation
to which the Trustee shall be a party, or any legal entity succeeding to all or substantially all of the trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided such legal 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 Notes 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 Notes so authenticated with the same
effect as if such successor Trustee had itself authenticated such Notes. In case any Notes shall not have been authenticated by
such predecessor Trustee, any such successor Trustee may authenticate and deliver such Notes, 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.


 




    	42



     


    

 


Section 7.11. Appointment of Authenticating Agent.


 


At any time when any of the Notes remain outstanding,
the Trustee may appoint an authenticating agent or agents which shall be authorized to act on behalf of the Trustee to authenticate
Notes issued upon exchange, registration of transfer or partial repayment thereof, and Notes 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 Issuer. Wherever reference is made in this Indenture to the authentication and delivery
of Notes 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 Issuer and shall at all times be a bank
or trust company or other legal entity organized and doing business and in good standing under the laws of the United States of
America or of any state or the District of Columbia, authorized under such laws to act as authenticating agent which Person shall
be eligible to serve as Trustee pursuant to the Trust Indenture Act with a combined capital and surplus of at least the amount
required under the Trust Indenture Act, 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 7.11, 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 7.11, such authenticating agent
shall resign immediately in the manner and with the effect specified in this Section 7.11.


 


Any legal entity into which an authenticating
agent may be merged or converted or with which it may be consolidated, or any legal entity resulting from any merger, conversion
or consolidation to which such authenticating agent shall be a party, or any legal entity succeeding to the agency or trust business
of an authenticating agent, shall continue to be an authenticating agent, provided such legal 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 may at any time resign
by giving written notice of resignation to the Trustee and to the Issuer. The Trustee may at any time terminate the agency of an
authenticating agent by giving written notice of termination to such authenticating agent and to the Issuer. 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 7.11, the Trustee may appoint a successor authenticating agent which shall be
acceptable to the Issuer and shall give notice of such appointment to all Holders of Notes by delivering or causing to be delivered
such notice to the Holders of Notes as they appear on the Note Register. 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.


 


The Issuer 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 is made pursuant to this Section
7.11, the Notes 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 Notes designated therein
referred to in the within-mentioned Indenture.

Section 7.12. Certain Duties and Responsibilities of the Trustee.


 


(a) With respect to the Notes, except during
the continuance of an Event of Default with respect to the Notes:


 


		(1)	the Trustee undertakes to perform such duties and 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; and



 


		(2)	the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions therein upon certificates
or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates
or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under
a duty to examine the same to determine whether or not they conform to the requirements of this Indenture, but shall not be under
any duty to verify the contents or accuracy thereof.



 


(b) In case an Event of Default has occurred
and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree
of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s
own affairs.


 


(c) No provision of this Indenture shall be
construed to relieve the Trustee from liability for its own gross negligence or willful misconduct, except that:


 


		(1)	this Subsection shall not be construed to limit the effect of Subsection (a) of this Section;



 


		(2)	the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved
that the Trustee was grossly negligent in ascertaining the pertinent facts;



 


		(3)	the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with
the written direction of the Holders of a majority in principal amount of the outstanding Notes relating to the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the
Trustee, under this Indenture; and



 


		(4)	no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability
in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured
to it. 



 




    	44



     


    

 


(d) Whether or not therein expressly so provided,
every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee
shall be subject to the provisions of this Section 7.12.


 


ARTICLE 8

THE NOTEHOLDERS


 


Section 8.01. Action by Noteholders.


 


Whenever in this Indenture it is provided that
the Holders of a specified percentage in aggregate principal amount of the Notes may take any action (including the making of any
demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of
taking any such action, the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or
any number of instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in writing, or (b)
by the record of the Holders of Notes voting in favor thereof at any meeting of Noteholders, or (c) by a combination of such instrument
or instruments and any such record of such a meeting of Noteholders. Whenever the Issuer or the Trustee solicits the taking of
any action by the Holders of the Notes, the Issuer or the Trustee may fix in advance of such solicitation a date as the record
date for determining Holders entitled to take such action. 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 Noteholders 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 Noteholders of record at the Close of Business on such record date shall be deemed to be Noteholders for the purposes of determining
whether Holders of the requisite proportion of outstanding Notes have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other act, and for that purpose the outstanding Notes shall be computed as
of such record date; provided that no such authorization, agreement or consent by the Noteholders 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.


 


Section 8.02. Proof of Execution by Noteholders.


 


Subject to the provisions of Sections 7.02 and
7.12, proof of the execution of any instrument by a Noteholder or its agent or proxy shall be sufficient if made in accordance
with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the
Trustee. The holding of Notes shall be proved by the registry of such Notes or by a certificate of the Note Registrar.


 


Section 8.03. Absolute Owners.


 


The Issuer, the Trustee, any Paying Agent, any
Exchange Agent and any Note Registrar may deem the Person in whose name such Note shall be registered upon the Note Register to
be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation
of ownership or other writing thereon made by any Person other than the Issuer or any Note Registrar) for the purpose of receiving
payment of or on account of the principal of (including the repurchase price upon repurchase pursuant to Article 3) and Interest
on such Note, for exchange of such Note and for all other purposes; and neither the Issuer nor the Trustee nor any Paying Agent
nor any exchange agent nor any Note Registrar shall be affected by any notice to the contrary. All such payments so made to any
Holder for the time being, or upon its order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy
and discharge the liability for monies payable upon any such Note.

Section 8.04. Issuer-Owned Notes Disregarded.


 


In determining whether the Holders of the requisite
aggregate principal amount of Notes have given any request, demand, authorization, direction, notice, consent or waiver under this
Indenture or whether a quorum is present at a meeting of Noteholders, Notes which are owned by the Issuer or any other obligor
upon the Notes or any Affiliate of the Issuer or any other obligor on the Notes, as such ownership shall be reflected on the Note
Register, shall be disregarded and deemed not to be outstanding for the purpose of any such determination. Notes so owned which
have been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.04 if the pledgee shall establish
to the satisfaction of the Trustee the pledgee’s right to vote such Notes and that the pledgee is not the Issuer, any other
obligor on the Notes or any Affiliate of the Issuer or any such other obligor. In the case of a dispute as to such right, any decision
by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Issuer
shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Issuer
to be owned or held by or for the account of any of the above described Persons, and, subject to Section 7.12, the Trustee shall
be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that
all Notes not listed therein are outstanding for the purpose of any such determination.


 


Section 8.05. Revocation of Consents; Future Holders Bound.


 


At any time prior to (but not after) the evidencing
to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage in aggregate principal
amount of the Notes specified in this Indenture in connection with such action, any Holder of a Note which is shown by the evidence
to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at
its Corporate Trust Office and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Note.
Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon
all future Holders and owners of such Note and of any Notes issued in exchange or substitution therefor, irrespective of whether
any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor.

Section 9.01. Supplemental Indentures Without Consent of Noteholders.


 


Without the consent of any Holder, the Issuer
(when authorized by a Board Resolution) and the Trustee, at any time and from time to time, may enter into an indenture or indentures
supplemental hereto, in form satisfactory to the Trustee, for any of the following purposes:


 


		(1)	to conform the terms of this Indenture or the Notes to the description thereof in the Offering Memorandum;

the assumption by a successor entity of the Issuer’s obligations under this Indenture;



 


		(3)	to add guarantees with respect to the Notes;



 


		(4)	to release a Subsidiary Guarantor from its obligations under the Guarantees or this Indenture in accordance with this Indenture;

    	46



     


    

 


		(7)	to add to the Issuer’s covenants or events of default such further covenants, events of default, restrictions or conditions
for the benefit of the Holders (or any other holders) or to otherwise make changes that would provide additional rights to the
Holders, or to surrender any right or power conferred upon the Issuer;



 


		(8)	to cure any ambiguity, defect or inconsistency in this Indenture or the Notes, or to make any other change that does not adversely
affect the legal rights of any Holder in any material respect as evidenced by an Officers’ Certificate;



 


		(9)	to provide for a successor Trustee;



 


		(10)	to comply with the applicable procedures of the Depositary; or



 


		(11)	in connection with any transaction described under Article 13, provide that the Notes are exchangeable for Reference Property,
subject to the provisions described under Section 13.07 and make certain related changes to the terms of the Notes to the extent
expressly required by this Indenture.



 


Upon the written request of the Issuer, accompanied
by an Officers’ Certificate and Opinion of Counsel stating that such amendment is authorized or permitted by the Indenture
and is legally valid, binding and enforceable against the Issuer and the Guarantors and a copy of the resolutions of the Board
of Directors certified by the General Partner’s Secretary or Assistant Secretary authorizing the execution of any supplemental
indenture, the Trustee is hereby authorized to join with the Issuer and the General Partner in the execution of any such supplemental
indenture, to make any further appropriate agreements and stipulations that may be therein contained and to accept the conveyance,
transfer and assignment of any property thereunder, but the Trustee shall not be obligated to, but may in its discretion, enter
into any supplemental indenture that affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise.


 


Any supplemental indenture authorized by the
provisions of this Section 9.01 may be executed by the Issuer and the Trustee without the consent of the Holders of any of the
Notes at the time outstanding, notwithstanding any of the provisions of Section 9.02.


 


Section 9.02. Supplemental Indenture With Consent of Noteholders.


 


With the consent (evidenced as provided in Article
8) of the Holders of not less than a majority in aggregate principal amount of the outstanding Notes affected by such supplemental
indenture, including without limitation consents obtained in connection with a purchase of, or tender or exchange offer for, Notes,
the Issuer, when authorized by a Board Resolutions, and the Trustee may enter into an indenture or indentures supplemental hereto
for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or
of modifying in any manner the rights of the Holders under this Indenture; provided, however, that no such supplemental
indenture shall, without the consent of the Holder of each outstanding Note affected thereby:


 


		(1)	reduce the percentage in aggregate principal amount of Notes outstanding necessary to waive any past Default or Event of Default;



 


		(2)	reduce the rate of interest on any Note or change the time for payment of interest on any Note;



 


		(3)	reduce the principal of any Note or change the Maturity Date of any Note;



 


		(4)	change the place or currency of payment on any Note;



 




    	47



     


    

 


		(5)	make any change that impairs or adversely affects the exchange rights of any Notes;



 


		(6)	reduce the Fundamental Change Repurchase Price of any Note or amend or modify in any manner adverse to the rights of the Holders
of the Notes the Issuer’s obligation to pay the Fundamental Change Repurchase Price, whether through an amendment or waiver
of provisions in the covenants, definitions related thereto or otherwise;



 


		(7)	impair the right of any Holder of Notes to receive payment of principal of, and interest, if any, on, its Notes, or the right
to receive the consideration due upon exchange of its Notes on or after the due dates therefore or to institute suit for the enforcement
of any such payment or delivery, as the case may be, with respect to such Holder’s Notes;



 


		(8)	modify the ranking provisions of this Indenture in a manner that is adverse to the rights of the Holders of the Notes; or



 


		(9)	make any change to the provisions of this Article 9 that requires each Holder’s consent or in the waiver provisions if
such change is adverse to the rights of Holders of the Notes.



 


It shall not be necessary for any act or consent
of Holders under this Section 9.02 to approve the particular form of any proposed supplemental indenture, but it shall be
sufficient if such act or consent shall approve the substance thereof. The Issuer may, but shall not be obligated to, fix a record
date for the purpose of determining the Persons entitled to consent to any indenture supplemental hereto. If a record date is fixed,
the Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to consent to such
supplemental indenture, whether or not such Holders remain Holders after such record date; provided that, unless
such consent shall have become effective by virtue of the requisite percentage having been obtained prior to the date which is
90 days after such record date, any such consent previously given shall automatically and without further action by any Holder
be cancelled and of no further effect.


 


Upon the written request of the Issuer, accompanied
by an Officers’ Certificate and Opinion of Counsel stating that such amendment is authorized or permitted by the Indenture
and is legally valid, binding and enforceable against the Issuer and the Guarantors and a copy of the Board Resolution authorizing
the execution of any supplemental indenture, and upon the filing with the Trustee of evidence of the consent of the Holders as
aforesaid, the Trustee shall join with the Issuer in the execution of such supplemental indenture unless such supplemental indenture
affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in
its discretion, but shall not be obligated to, enter into such supplemental indenture. 


 


Section 9.03. Notation on Notes.


 


Notes authenticated and delivered after the
execution of any supplemental indenture pursuant to the provisions of this Article 9 may bear a notation in form approved
by the Trustee as to any matter provided for in such supplemental indenture. If the Issuer or the Trustee shall so determine, new
Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture
contained in any such supplemental indenture may, at the Issuer’s expense, be prepared and executed by the Issuer, authenticated
by the Trustee (or an authenticating agent duly appointed by the Trustee pursuant to Section 7.11) and delivered in exchange for
the Notes then outstanding, upon surrender of such Notes then outstanding.


 




    	48



     


    

 


Section 9.04. Evidence of Compliance of Supplemental Indenture
to Be Furnished to Trustee.


 


Prior to entering into any supplemental indenture
pursuant to this Article 9, the Trustee shall be provided with an Officers’ Certificate and an Opinion of Counsel as
conclusive evidence that any supplemental indenture executed pursuant hereto complies with the requirements of this Article 9
and is otherwise authorized or permitted by this Indenture.


 


Section 9.05. Notice of Amendment or Supplement.


 


After an amendment or supplement under this
Article 9 becomes effective, the Issuer shall provide to the Holders a notice briefly describing such amendment or supplement.
However, the failure to give such notice to all the Holders, or any defect in the notice, shall not impair or affect the validity
of the amendment or supplement. In addition, any such amendment filed with the Commission through the EDGAR system (or any successor
thereto) shall be deemed to have been sent to the Holders for purposes of this Section 9.05.


 


ARTICLE 10

CONSOLIDATION, MERGER AND SALE OF ASSETS


 


Section 10.01. Issuer May Consolidate on Certain Terms.


 


Subject to the provisions of this Article 10,
the Issuer shall not amalgamate or consolidate with, merge with or into or convey, transfer or lease its properties and assets
substantially as an entirety to another Person, unless:


 


		(1)	the Issuer shall be the surviving Person or the resulting, surviving or transferee Person (the “Successor Company”),
if not the Issuer, shall be 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 Issuer) shall expressly assume, by supplemental indenture, executed and delivered
to the Trustee, in form satisfactory to the Trustee, all of the obligations of the Issuer under the Notes and this Indenture as
applicable to the Notes; and



 


		(2)	immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under
this Indenture.



 


Section 10.02. Issuer Successor to Be Substituted.


 


In case of any such amalgamation, consolidation,
merger, conveyance, transfer or lease and upon the assumption by the Successor Company, by supplemental indenture, executed and
delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of (including
any Fundamental Change Repurchase Price), accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on all
of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon exchange of the Notes
and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Issuer under
this Indenture, such Successor Company shall succeed to and be substituted for, and may exercise every right and power of, the
Issuer under this Indenture, with the same effect as if it had been named herein as the party of the first part. Such Successor
Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Issuer any or all of the Notes
issuable hereunder which theretofore shall not have been signed by the Issuer and delivered to the Trustee; and, upon the order
of such Successor Company instead of the Issuer and subject to all the terms, conditions and limitations in this Indenture prescribed,
the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have
been signed and delivered by the officers of the Issuer to the Trustee for authentication, and any Notes that such Successor Company
thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the
terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such
amalgamation, consolidation, merger, conveyance or transfer (but not in the case of a lease), the Person named as the “Issuer”
in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this
Article 10 may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall
be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture.


 




    	49



     


    

 


In case of any such amalgamation, consolidation,
merger, 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 10.03. Opinion of Counsel to be Given to Trustee.


 


In the case of any such amalgamation, merger,
consolidation, conveyance, transfer or lease the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel
stating that any such amalgamation, consolidation, merger, conveyance, transfer or lease and any such assumption and, if a supplemental
indenture is required in connection with such transaction, such supplemental indenture comply with the provisions of this Article
10 and constitutes the legal, valid and binding obligations of the Issuer (subject to customary exceptions and assumptions).


 


ARTICLE 11

SATISFACTION AND DISCHARGE OF INDENTURE


 


Section 11.01. Satisfaction and Discharge of Indenture.


 


This Indenture shall cease to be of further
effect (except as to (i) rights hereunder of Holders of the Notes to receive all amounts owing upon the Notes and the other rights,
duties and obligations of Holders of the Notes, as beneficiaries hereof with respect to the amounts, if any, so deposited with
the Trustee and (ii) the rights, obligations and immunities of the Trustee hereunder), and the Trustee, upon demand of and at the
expense of the Issuer, shall execute instruments in form and substance satisfactory to the Trustee and the Issuer acknowledging
satisfaction and discharge of this Indenture when:


 


(a) either


 


		(1)	all Notes theretofore authenticated and delivered (other than (A) Notes which have been destroyed, lost or stolen and which
have been replaced or paid as provided in Section 2.06, and (B) Notes for whose payment money has theretofore been deposited in
trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from such trust, as provided
in Section 11.03) have been delivered to the Trustee for cancellation; or



 


		(2)	all such Notes not theretofore delivered to the Trustee for cancellation have become due and payable, and the Issuer has irrevocably
deposited or caused to be deposited with the Trustee, a Paying Agent or the Exchange Agent (other than the Issuer or any of its
Affiliates), as applicable, as trust funds in trust cash and/or shares of Common Stock (as applicable under the terms of this Indenture)
in an amount sufficient to pay and discharge (without the necessity of investing such amount of cash deposited) the entire indebtedness
on such Notes not theretofore delivered to the Trustee for cancellation, for principal and Interest to the date of such deposit
(in the case of Notes which have become due and payable) or to the Stated Maturity or Fundamental Change Repurchase Date, as the
case may be;



 


(b) the Issuer has paid or caused to be paid
all other sums payable hereunder by the Issuer; and


 




    	50



     


    

 


(c) the Issuer has delivered to the Trustee
an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating
to the satisfaction and discharge of this Indenture have been complied with.


 


Section 11.02. Application of Trust Funds.


 


All money deposited with the Trustee pursuant
to Section 11.01 shall be held in trust, uninvested, and applied by it, in accordance with the provisions of the Notes and this
Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as its own Paying Agent) as
the Trustee may determine, to the Persons entitled thereto, of the principal and any Interest for whose payment such money has
been deposited with or received by the Trustee, but such money need not be segregated from other funds except to the extent required
by law. All moneys deposited with the Trustee (and held by it or any Paying Agent) for the payment of Notes subsequently exchanged
shall be returned to the Issuer upon request.


 


Section 11.03. Return of Unclaimed Monies.


 


Subject to the restrictions of applicable law,
the Trustee and each Paying Agent shall pay to the Issuer upon request any money held by them for the payment of principal or Interest
that remains unclaimed for two years after a right to such money has matured; provided, however, that the Trustee
or such Paying Agent, before being required to make any such payment, may, at the expense of the Issuer, either publish in a newspaper
of general circulation in the City of New York, or cause to be mailed to each Holder entitled to such money, notice that such money
remains unclaimed and that after a date specified therein, which shall be at least thirty (30) calendar days from the date of such
mailing or publication, any unclaimed balance of such money then remaining will be repaid to the Issuer. After payment to the Issuer,
Holders entitled to money must look to the Issuer for payment as general creditors unless an applicable abandoned property law
designates another person, and the Trustee and each Paying Agent shall be relieved of all liability with respect to such money.


 


Section 11.04. Reinstatement.


 


If the Trustee or the Paying Agent is unable
to apply any money in accordance with this Article 11 by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Issuer’s obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to this Article 11 until such time as the Trustee
or Paying Agent is permitted to apply all money held in trust with respect to the Notes; provided, however, that
if the Issuer makes any payment of principal of or Interest on any Notes following the reinstatement of its obligations, the Issuer
shall be subrogated to the rights of the Holders of the Notes to receive such payment from the money so held by the Trustee or
Paying Agent in trust.

or agreement of the Issuer (i) in this Indenture or in any supplemental indenture or (ii) in any Note, or because of the creation
of any indebtedness represented thereby, shall be had against any incorporator, stockholder, partner, member, manager, employee,
agent, officer, director or subsidiary, as such, past, present or future, of the General Partner, the Issuer or any of the General
Partner’s or Issuer’s subsidiaries or of any successor thereto, either directly or through the General Partner, the
Issuer or any of the General Partner’s or Issuer’s subsidiaries or of any successor thereto, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood
that all such liability is hereby expressly waived and released as a condition of, and as a consideration for, the execution of
this Indenture, and the issue of the Notes.

ARTICLE 13

EXCHANGE OF NOTES


 


Section 13.01. Right to Exchange.


 


(a) Upon compliance with the provisions of this
Indenture, at any time prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date,
each Holder of a Note not previously repurchased shall have the right, at such Holder’s option, to exchange all or any portion
(if the portion to be exchanged is $1,000 principal amount or an integral multiple thereof) of such Note at the Exchange Rate per
$1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section 13.03, the “Exchange
Obligation”).


 


(b) Notwithstanding any other provision of the
Notes or this Indenture, no Holder of Notes will be entitled to receive Common Stock following exchange of such Notes to the extent
that receipt of such Common Stock would cause such Holder (after application of certain constructive ownership rules) to exceed
the ownership limits contained in the General Partner’s charter. If any delivery of shares of Common Stock owed to a Holder
upon exchange of Notes is not made, in whole or in part, as a result of the limitations described in this Section 13.01(b), the
Issuer’s obligation to make such delivery shall not be extinguished and the Issuer shall deliver such shares as promptly
as practicable after any such exchanging Holder gives notice to the Issuer that such delivery would not result in it being the
beneficial or constructive owner of more than 9.8% (by value or number, whichever is more restrictive) of the shares of Common
Stock or of the General Partner’s Capital Stock, outstanding at such time.


 


(c) A Note in respect of which a Holder has
delivered a Fundamental Change Repurchase Notice exercising such Holder’s right to require the Issuer to repurchase such
Note pursuant to Section 3.02 may be exchanged only if such Fundamental Change Repurchase Notice is properly withdrawn in accordance
with, and within the time periods set forth in, this Indenture.


 


Section 13.02 Exchange Procedures. 


 


(a) Subject to this Section 13.02, before any
Holder of a Note shall be entitled to exchange a Note as set forth above, such Holder shall (1) 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 13.02(f) and (2) in the case of a
Note in definitive form (i) complete and manually sign an irrevocable notice as set forth in the Form of Exchange Notice attached
as Attachment 2 to the Form of Note attached as Exhibit A hereto (the “Exchange Notice”), (ii) deliver
the Exchange Notice at the office of the Exchange Agent and state in writing therein the principal amount of Notes to be exchanged
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 Exchange Obligation to be registered, (iii) surrender such Notes, duly endorsed to
the Issuer or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Exchange Agent,
(iv) if required, furnish appropriate endorsements and transfer documents (v) 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 13.02(f) and (vi) provide
a Form W-9 or such other appropriate tax withholding document. The Trustee (and if different, the Exchange Agent) shall notify
the Issuer of any exchange pursuant to this Article 13 on the Exchange Date for such exchange. No Exchange Notice with respect
to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to
the Issuer in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with
Section 3.03.


 




    	52



     


    

 


If more than one Note shall be surrendered for
exchange at one time by the same Holder, the Exchange 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.


 


(b) A Note shall be deemed to have been exchanged
immediately prior to the Close of Business on the date (the “Exchange Date”) that the Holder has complied with
the requirements set forth in subsection (a) above. Except as set forth in Section 13.03(a) and 13.05(a), the Issuer shall pay
or deliver, as the case may be, the consideration due in respect of the Exchange Obligation on the third Business Day immediately
following the relevant Exchange Date, if the Issuer elects Physical Settlement, or on the third Business Day immediately following
the last Trading Day of the Cash Settlement Averaging Period, in the case of any other Settlement Method. If any shares of Common
Stock are due to an exchanging Holder, the General Partner shall issue or cause to be issued, and deliver (if applicable) to the
Exchange Agent or to such Holder, or such Holder’s nominee or nominees, the full number of shares of Common Stock to which
such Holder shall be entitled, in book-entry format through the Depositary, in satisfaction of the Issuer’s Exchange Obligation.


 


Each exchange shall be deemed to have been effected
as to any such Notes (or portion thereof) surrendered for exchange at the Close of Business on the applicable Exchange Date; provided,
however, that the person in whose name any shares of Common Stock shall be deliverable upon exchange shall be treated as
a holder of record of such shares as of the Close of Business on (i) the relevant Exchange Date (in the case of Physical Settlement)
or (ii) the last Trading Day of the relevant Cash Settlement Averaging Period (in the case of Combination Settlement), as the case
may be. At the Close of Business on the Exchange Date for a Note, the exchanging Holder shall no longer be the Holder of such Note. 


 


(d) Physical Notes. If any Note in definitive
form in a denomination greater than $1,000 shall be surrendered for partial exchange, the Issuer shall execute and the Trustee
shall authenticate and deliver to or upon the written order of the Holder of the Notes so surrendered a new Note or Notes in definitive
form in authorized denominations in an aggregate principal amount equal to the unexchanged portion of the surrendered Note, without
payment of any service charge by the exchanging Holder, but, if required by the Issuer or the Trustee, with payment of a sum sufficient
to cover any documentary, stamp or similar issue or 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 being different
from the name of the Holder of the old Notes surrendered for such exchange.


 


(e) Global Notes. Upon the exchange of
a beneficial interest in a Global Note, the Trustee or the Custodian at the direction of the Trustee, shall make a notation on
such Global Note in its records as to the reduction in the principal amount represented thereby. The Issuer shall notify the Trustee
in writing of any exchanges of Notes effected through any Exchange Agent other than the Trustee. 


 


(f) Interest Due Upon Exchange. Upon
exchange, a Holder shall not receive any separate cash payment or additional shares of Common Stock representing accrued and unpaid
Interest or Additional Interest, if any, except as set forth below. The Issuer’s settlement of the full Exchange Obligation
shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any,
on the Note, to, but not including, the relevant Exchange Date. As a result, accrued and unpaid interest, if any, to, but not including,
the relevant Exchange Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon exchange of
Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of
the cash paid upon such exchange. Notwithstanding the foregoing, if Notes are exchanged after the Close of Business on a Regular
Record Date for the payment of Interest, but prior to the Open of Business on the immediately following Interest Payment Date,
Holders of such Notes as of the Close of Business on such Regular Record Date will receive the full amount of Interest payable
on such Notes on the corresponding Interest Payment Date notwithstanding the exchange. However, Notes surrendered for exchange
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 exchanged on the corresponding
Interest Payment Date (regardless of whether the exchanging Holder was the holder of record on the corresponding Regular Record
Date); provided that no such payment shall be required (1) for exchanges following the Regular Record Date immediately preceding
the Maturity Date; (2) if the Issuer has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and
on or prior to the Business Day immediately following the corresponding Interest Payment Date; or (3) to the extent of any Defaulted
Amounts, if any Defaulted Amounts exists at the time of exchange with respect to such Note. For the avoidance of doubt, all Holders
of record on the Regular Record Date immediately preceding the Maturity Date and any Fundamental Change Repurchase Date shall receive
the full Interest payment due on the Maturity Date or other applicable Interest Payment Date in cash regardless of whether their
Notes have been exchanged following such Regular Record Date.


 




    	53



     


    

 


In no event will a Holder be entitled to receive
any dividend or other distribution with respect to any Common Stock issued on exchange of such Holder’s Notes if the applicable
Exchange Date is after the record date for such dividend or distribution. Prior to the settlement of any exchange in accordance
with this Section 13.02, a Holder shall not be the owner of any Common Stock issuable upon exchange of such Holder’s Notes.


 


(g) Taxes Due upon Exchange. If a Holder
submits a Note for exchange, the Issuer shall pay any documentary, stamp or similar issue or transfer tax due on the issue of any
shares of Common Stock upon exchange on the Notes, unless the tax is due because the Holder requests such shares to be issued in
a name other than the Holder’s name, in which case the Holder shall pay that tax. The Exchange Agent may refuse to deliver
the certificates representing the shares of Common Stock being issued in a name other than the 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.


 


Section 13.03 Settlement Upon Exchange.


 


(a) Settlement Amount. Subject to this
‎Section 13.03(a), ‎Section 13.03(b) and ‎Section 13.07(a), upon exchange of any Note, the Issuer shall pay or deliver,
as the case may be, to the exchanging Holder, in respect of each $1,000 principal amount of Notes being exchanged, cash (“Cash
Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of
Common Stock in accordance with subsection ‎(b) of this ‎Section 13.03 (“Physical Settlement”) or a
combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of
Common Stock in accordance with subsection ‎(b) of this ‎Section 13.03 (“Combination Settlement”), at
its election, as set forth in this ‎Section 13.03.


 


All exchanges for which the relevant Exchange
Date occurs on or after November 21, 2023, shall be settled using the same Settlement Method. Except for any exchanges for which
the relevant Exchange Date occurs on or after November 21, 2023, the Issuer shall use the same Settlement Method for all exchanges
occurring on the same Exchange Date, but the Issuer shall not have any obligation to use the same Settlement Method with respect
to exchanges with different Exchange Dates.


 


If, in respect of any Exchange Date, the Issuer elects a Settlement
Method, the Issuer will deliver a written notice (the “Settlement Notice”) to the Trustee and the Exchange Agent
(if other than the Trustee) and the exchanging Holders (through the Exchange Agent) of the relevant Settlement Method in respect
of such Exchange Date no later than the Close of Business on the second Trading Day immediately following the relevant Exchange
Date (or, in the case of any exchanges for which the relevant Exchange Date occurs on or after November 21, 2023, no later than
November 21, 2023). If the Issuer does not elect a Settlement Method prior to the deadline set forth in the immediately preceding
sentence, the Issuer shall no longer have the right to elect Cash Settlement or Physical Settlement with respect to that Exchange
Date and the Issuer shall be deemed to have elected Combination Settlement in respect of its Exchange Obligation, and the Specified
Dollar Amount per $1,000 principal amount of Notes shall be equal to $1,000. Such 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 per $1,000 principal amount of Notes. If the Issuer delivers a Settlement Notice electing Combination Settlement
in respect of its Exchange Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount of Notes in such
Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000.

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


 


		(1)	if the Issuer elects to satisfy its Exchange Obligation in respect of such exchange by Physical Settlement, the Issuer shall
deliver to the exchanging Holder a number of shares of Common Stock equal to (A)(i) the aggregate principal amount of Notes to
be exchanged divided by (ii) $1,000, multiplied by (B) the Exchange Rate in effect on the Exchange Date (plus cash
in lieu of any fractional share of Common Stock issuable on exchange as set forth in ‎Section 13.03(b));



 


		(2)	if the Issuer elects to satisfy its Exchange Obligation in respect of such exchange by Cash Settlement, the Issuer shall pay
to the exchanging Holder, in respect of each $1,000 principal amount of Notes being exchanged, cash in an amount equal to the sum
of the Daily Exchange Values for each of the 20 consecutive Trading Days during the related Cash Settlement Averaging Period; and



 


		(3)	if the Issuer elects (or is deemed to have elected) to satisfy its Exchange Obligation in respect of such exchange by Combination
Settlement, the Issuer shall pay or deliver, as the case may be, to the exchanging Holder, in respect of each $1,000 principal
amount of Notes being exchanged, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 20 consecutive
Trading Days during the related Cash Settlement Averaging Period (plus cash in lieu of any fractional share of Common Stock issuable
upon exchange as set forth in ‎Section 13.03(b)).



 


In the case of Cash Settlement or Combination
Settlement, the Daily Settlement Amounts (if applicable) and the Daily Exchange Values (if applicable) shall be determined by the
Issuer promptly following the last day of the Cash Settlement Averaging Period. Promptly after such determination of the Daily
Settlement Amounts or the Daily Exchange Values, as the case may be, and the amount of cash payable in lieu of delivering any fractional
share of Common Stock, the Issuer shall notify the Trustee and the Exchange Agent (if other than the Trustee) in writing of the
Daily Settlement Amounts or the Daily Exchange Values, as the case may be, and the amount of cash payable in lieu of delivering
fractional shares of Common Stock. The Trustee and the Exchange Agent (if other than the Trustee) shall have no responsibility
for calculating the Daily Exchange Value or any other settlement calculations.


 


Notwithstanding the foregoing, if any information
required to calculate the Settlement Amount deliverable is not available as of the applicable settlement date, the Issuer will
deliver the additional shares of Common Stock resulting from such adjustment on the third Trading Day after the earliest Trading
Day on which such calculation can be made.


 


(b) Fractional Shares. Notwithstanding
the foregoing, the Issuer will not issue fractional shares of Common Stock as part of the Settlement Amount due with respect to
any exchanged Note in respect of which shares of Common Stock are deliverable. Instead, if any such Settlement Amount includes
a fraction of a share of Common Stock, the Issuer will, in lieu of delivering such fraction of a share of Common Stock, pay an
amount of cash equal to the product of (i) such fraction of a share and (ii) the Daily VWAP of the Common Stock on the relevant
Exchange Date (in the case of Physical Settlement) or on the last Trading Day of the applicable Cash Settlement Averaging Period
(in the case of Combination Settlement), subject in each case to the following paragraph. For each Note surrendered for Exchange,
if the Issuer has elected Combination Settlement, the full number of shares that shall be issued upon exchange thereof shall be
computed on the basis of the aggregate Daily Settlement Amounts for the relevant Cash Settlement Averaging Period and any fractional
shares remaining after such computation shall be paid in cash.


 




    	55



     


    

 


If a Holder surrenders more than one Note for
exchange on a single Exchange Date, the Issuer will calculate the amount of cash and the number of shares of Common Stock due with
respect to such Notes as if such Holder had surrendered for exchange one Note having an aggregate principal amount equal to the
sum of the principal amounts of each of the Notes surrendered for exchange by such Holder on such Exchange Date.


 


(d) Notices. Whenever an Exchange Date
occurs with respect to a Note, the Exchange Agent will (provided it has received an Exchange Notice from the Depositary or the
Holder), as promptly as possible, and in no event later than the second Business Day immediately following such Exchange Date,
deliver to the Issuer and the Trustee, if it is not then the Exchange Agent, notice that an Exchange Date has occurred, which notice
will state such Exchange Date, the principal amount of Notes exchanged on such Exchange Date and the names of the Holders that
exchanged Notes on such Exchange Date. 


 


Section 13.04. Adjustment of Exchange Rate.


 


The Exchange Rate will be adjusted as described
in this Section 13.04, except that the Issuer shall not make any adjustment to the Exchange Rate if Holders of the Notes participate
(other than in the case of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon
the same terms as holders of the Common Stock and as a result of holding the Notes, in any of the transactions described below
without having to exchange their Notes, as if they held a number of shares of Common Stock equal to the applicable Exchange Rate,
multiplied by the principal amount (expressed in thousands) of Notes held by such Holder.


 


(a) If the General Partner exclusively issues
shares of Common Stock as a dividend or distribution on all or substantially all shares of the Common Stock, or if the General
Partner effects a share split or share combination, the Exchange Rate will be adjusted based on the following formula:


 


	 	 	 	 	 
	ER1	 	=	 	ER0 x  OS1 
	 	 	 	 	           OS0


 


where,


 


	ER0	 	=	 	the Exchange 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;
	 	 	 	 	 
	ER1	 	=	 	the Exchange Rate in effect immediately after the Open of Business on such Ex-Dividend Date or such effective date, as applicable;
	 	 	 	 	 
	OS0	 	=	 	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date or such effective date, as applicable, before giving effect to such dividend, distribution, share split or share combination; and
	 	 	 	 	 
	OS1	 	=	 	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination, as applicable.


 




    	56



     


    

 


Any adjustment made under this Section 13.04(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 13.04(a) is declared but not so paid or made, the Exchange Rate shall be immediately readjusted,
effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Exchange Rate that
would then be in effect if such dividend or distribution had not been declared.


 


(b) If the General Partner issues to all or
substantially all holders of the 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 the 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 Exchange
Rate will be increased based on the following formula:


 


	
         ER1
	 	=	 	ER0 x  OS0 + X
	 	 	 	 	           OS0 + Y


 


where,


 


	ER0	 	=	 	the Exchange Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such issuance;
	 	 	 	 	 
	ER1	 	=	 	the Exchange 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 13.04(b)
will 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 such rights, options or warrants are not exercised
prior to their expiration or shares of Common Stock are not delivered upon the exercise of such rights, options or warrants, the
Exchange Rate shall be decreased to the Exchange 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, or if such rights, options or warrants are not exercised prior to their
expiration, the Exchange Rate shall be decreased to be the Exchange Rate that would then be in effect if such Ex-Dividend Date
for such issuance had not occurred.


 


For purposes of this Section 13.04(b), in determining
whether any rights, options or warrants entitle the holders of the Common Stock to subscribe for or purchase shares of the Common
Stock at a price per share 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 for such issuance, and in determining
the aggregate offering price of such shares of the Common Stock, there shall be taken into account any consideration received by
the General Partner for such rights, options or warrants and any amount payable on exercise or exchange thereof, the value of such
consideration, if other than cash, to be determined by the Board of Directors.


 




    	57



     


    

 


(c) If the General Partner distributes shares
of its Capital Stock, evidences of its indebtedness, other assets or property of the General Partner or rights, options or warrants
to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding:


 


		(1)	dividends, distributions, rights, options or warrants as to which an adjustment was effected pursuant to Section 13.04(a) or
(b) hereof;



 


		(2)	dividends or distributions paid exclusively in cash as to which the provisions set forth below in Section 13.04(d) hereof shall
apply; and



 


		(3)	Spin-Offs as to which the provisions set forth below in this Section 13.04(c) shall apply;



 


then the Exchange Rate shall be increased based on the following
formula:


 


	ER1	 	=	 	ER0 x      SP0
	 	 	 	 	           SP0 - FMV


where,


 


	ER0	 	=	 	the Exchange Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;
	 	 	 	 	 
	ER1	 	=	 	the Exchange 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 shares of the General Partner’s Capital Stock, evidences of the General Partner’s indebtedness, other assets or property of the General Partner or rights, options or warrants to acquire the General Partner’s Capital Stock or other securities distributed with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such distribution.


 


Notwithstanding the foregoing, if “FMV”
(as defined above) is equal to or greater than the “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 of Notes it holds, at the same time and upon the
same terms as holders of the Common Stock, the amount and kind of the General Partner’s Capital Stock, evidences of the General
Partner’s indebtedness, other assets or property of the General Partner or rights, options or warrants to acquire the General
Partner’s Capital Stock or other securities that such Holder would have received as if such Holder owned a number of shares
of Common Stock equal to the Exchange Rate in effect on the Ex-Dividend Date for the distribution.


 




    	58



     


    

 


Any increase made under the portion of this
Section 13.04(c) will 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 Exchange Rate shall be decreased to be the Exchange Rate that would then be in effect
if such dividend or distribution had not been declared.


 


With respect to an adjustment pursuant to this
Section 13.04(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, that are listed or quoted
(or will be listed or quoted upon the consummation of the distribution) on a U.S. national securities exchange (a “Spin-Off”),
the Exchange Rate will be increased based on the following formula: 


 


	ER1	 	=	 	ER0 x  FMV0 + MP0 
	 	 	 	 	                  MP0


where,


 


	ER0	 	=	 	the Exchange Rate in effect immediately prior to the end of the Valuation Period (as defined below);
	 	 	 	 	 
	ER1	 	=	 	the Exchange Rate in effect immediately after the Open of Business on the end of the Valuation Period;
	 	 	 	 	 
	FMV0	 	=	 	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock 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 Common Stock over the Valuation Period.


 


The adjustment to the applicable Exchange Rate
under the preceding paragraph of this Section 13.04(c) will be made immediately after the Open of Business on the day after
the last Trading Day of the Valuation Period, but will be given effect as of the Open of Business on the Ex-Dividend Date for the
Spin-Off. If the Ex-Dividend Date for the Spin-Off is less than 10 Trading Days prior to, and including, the end of the Cash Settlement
Averaging Period in respect of any exchange, references within this Section 13.04(c) to 10 Trading Days shall be deemed replaced,
for purposes of calculating the affected Daily Exchange Values in respect of that exchange, 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
Cash Settlement Averaging Period. For purposes of determining the applicable Exchange Rate, in respect of any exchange during the
10 Trading Days commencing on the Ex-Dividend Date for any Spin-Off, references within the portion of this Section 13.04(c)
related to “Spin-Offs” to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have
elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, and including, the relevant Exchange Date.


 




    	59



     


    

 


For purposes of this ‎Section 13.04(c) (and
subject in all respects to ‎Section 13.04(g)), rights, options or warrants distributed by the General Partner to all holders
of the Common Stock entitling them to subscribe for or purchase shares of the General Partner’s Capital Stock, including
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 Common Stock; (ii) are not exercisable;
and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes
of this ‎Section 13.04(c) (and no adjustment to the Exchange Rate under this ‎Section 13.04(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 Exchange Rate shall be made under this ‎Section 13.04(c). If any
such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this 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 Exchange Rate under this ‎Section 13.04(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 Exchange Rate shall be readjusted as if such rights, options or warrants
had not been issued and (y) the Exchange 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 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 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 Exchange Rate shall be readjusted as if such rights, options and warrants had not been issued.


 


For purposes of ‎Section 13.04(a), ‎Section
13.04(b) and this ‎Section 13.04(c), if any dividend or distribution to which this ‎Section 13.04(c) is applicable also
includes one or both of:


 


(A)       a
dividend or distribution of shares of Common Stock to which ‎Section 13.04(a) is applicable (the “Clause A Distribution”);
or


 


(B)       a
dividend or distribution of rights, options or warrants to which ‎Section 13.04(b) is applicable (the “Clause B Distribution”),


 


then, in either case, (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
13.04(c) is applicable (the “Clause C Distribution”) and any Exchange Rate adjustment required by this ‎Section
13.04(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 Exchange Rate adjustment required by ‎Section 13.04(a)
and ‎Section 13.04(b) with respect thereto shall then be made, except that, if determined by the Issuer (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 such effective date” within
the meaning of ‎Section 13.04(a) or “outstanding immediately prior to the Open of Business on such Ex-Dividend Date”
within the meaning of ‎Section 13.04(b).


 


(d) If the General Partner makes any cash dividend
or distribution to all or substantially all holders of the Common Stock, to the extent that the aggregate of all such cash dividends
or distributions paid in any quarter exceeds the Dividend Threshold Amount (as defined below) for such quarter, the Exchange Rate
shall be adjusted based on the following formula: 


 


	ER1	 	=	 	ER0 x  (SP0 - DTA) 
	 	 	 	 	           (SP0 – C)


 


where,


 




    	60



     


    

 


	ER0	 	=	 	the Exchange Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution;
	 	 	 	 	 
	ER1	 	=	 	the Exchange Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution;
	 	 	 	 	 
	SP0	 	=	 	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution;
	 	 	 	 	 
	DTA	 	=	 	the “Dividend Threshold Amount,” which shall initially be $0.35 per share per quarter; and
	 	 	 	 	 
	C	 	=	 	the amount in cash per share that the General Partner distributes to all or substantially all holders of the Common Stock.


 


The Dividend Threshold Amount is subject to
adjustment on an inversely proportional basis whenever the Exchange Rate is adjusted other than adjustments made pursuant to this
Section 13.04(d). If an adjustment is required to be made as set forth in this Section 13.04(d) as a result of a distribution that
is not a regular quarterly dividend, the Dividend Threshold Amount will be deemed to be zero with respect to that particular adjustment.


 


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 it holds, at the same time and upon the same terms as holders of shares of the
Common Stock, the amount of cash that such Holder would have received if such Holder had owned a number of shares of Common Stock
equal to the Exchange Rate on the Ex-Dividend Date for such cash dividend or distribution.


 


Any increase made under this Section 13.04(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 Exchange 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 Exchange Rate that would then be in effect if such dividend
or distribution had not been declared.


 


(e) If the General Partner or any of its Subsidiaries
make a payment in respect of a tender offer 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 the Common Stock exceeds 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 last date on which
tenders or exchanges may be made pursuant to such tender or exchange offer (the “Expiration Date”), the Exchange
Rate shall be increased based on the following formula: 


 


	ER1	 	=	 	ER0 x  AC + (SP1 x OS1) 
	 	 	 	 	                  OS0 x SP1


 


where,


 


	ER0	 	=	 	the Exchange Rate in effect immediately prior to the Close of Business on the Expiration Date;
	 	 	 	 	 
	ER1	 	=	 	the Exchange Rate in effect immediately after the Close of Business the Expiration Date;


 




    	61



     


    

 


	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 offer or exchange offer;
	 	 	 	 	 
	OS0	 	=	 	the number of shares of Common Stock outstanding immediately prior to the expiration time of the tender or exchange offer on the Expiration Date (prior to giving effect to the purchase of all shares accepted for purchase or exchange in such tender offer or exchange offer);
	 	 	 	 	 
	OS1	 	=	 	the number of shares of Common Stock outstanding immediately after the expiration time of the tender or exchange offer on the Expiration Date (after giving effect to the purchase of all shares 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 Expiration Date.


 


The adjustment to the applicable Exchange Rate
under the preceding paragraph of this Section 13.04(e) will be given effect at the Open of Business on the Trading Day next succeeding
the Expiration Date. If the Trading Day next succeeding the Expiration Date is less than 10 Trading Days prior to, and including,
the end of the Cash Settlement Averaging Period in respect of any exchange, references within this Section 13.04(e) to 10 Trading
Days shall be deemed replaced, for purposes of calculating the affected Daily Exchange Values in respect of that exchange, 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 Cash Settlement Averaging Period. For purposes of determining the applicable Exchange
Rate, in respect of any exchange during the 10 Trading Days commencing on the Trading Day next succeeding the Expiration Date,
references within this Section 13.04(e) to 10 Trading Days shall be deemed replaced 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 relevant Exchange
Date.


 


(f) Special Settlement Provisions. Notwithstanding
anything to the contrary herein with respect to exchanged Notes as to which Combination Settlement is applicable, if a Holder exchanges
a Note and the Daily Settlement Amount for any Trading Day during the Cash Settlement Averaging Period applicable to such Note: 


 


		(1)	is calculated based on an Exchange Rate adjusted on account of any event described in Sections 13.04(a) through (e) hereof;
and



 


		(2)	includes any shares of Common Stock that, but for this provision, would entitle their holder to participate in such event;



 


then, although the Issuer will otherwise treat such Holder as the
holder of record of such shares of Common Stock on the last Trading Day of such Cash Settlement Averaging Period, the Issuer will
not permit such Holder to participate in such event on account of such shares of Common Stock.


 


In addition, if a Holder exchanges a Note to
which Cash Settlement or Combination Settlement is applicable and:


 


		(1)	the record date, effective date or Expiration Date for any event that requires an adjustment to the Exchange Rate under any
of Sections 13.04(a) through (e) hereof occurs:



 








    	62



     


    







 


		(A)	on or after the first Trading Day of such Cash Settlement
Averaging Period; and



 


		(B)	on or prior to the last Trading Day of such Cash Settlement
Averaging Period; and



 


		(2)	the Daily Settlement Amount for any Trading Day in such
Cash Settlement Averaging Period that occurs on or prior to such record date, effective date or Expiration Date:



 


		(A)	includes shares of the Common Stock that do not entitle
their holder to participate in such event; and



 


		(B)	is calculated based on an Exchange Rate that is not adjusted
on account of such event;



 


then, on account of such exchange, the Issuer will, on such
record date, effective date or Expiration Date, treat such Holder, as a result of having exchanged such Notes, as though it were
the record holder of a number of shares of Common Stock equal to the total number of shares of Common Stock that:


 


		(1)	are deliverable as part of the Daily Settlement Amount:



 


		(A)	for a Trading Day in such Cash Settlement Averaging Period
that occurs on or prior to such record date, effective date or Expiration Date; and



 


		(B)	is calculated based on an Exchange Rate that is not adjusted
for such event; and



 


		(2)	if not for this provision, would not entitle such Holder
to participate in such event.



 


Notwithstanding anything to the contrary
herein, if an Exchange Rate adjustment becomes effective on any Ex-Dividend Date as described above, and a Holder that has exchanged
its Notes on or after such Ex-Dividend Date and on or prior to the related Regular Record Date would be treated as the record holder
of shares of Common Stock as of the related Exchange Date in accordance with the provisions of Section 13.02(b) based on an adjusted
Exchange Rate for such Ex-Dividend Date, then, notwithstanding the foregoing Exchange Rate adjustment provisions, the Exchange
Rate adjustment relating to such Ex-Dividend Date will not be made for such exchanging Holder. Instead, such Holder will 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.


 


(g) Poison Pill. Whenever a Holder
exchanges a Note, to the extent that the General Partner has a rights plan in effect, the Holder exchanging such Note will receive,
in addition to any shares of Common Stock received in connection with such exchange, if any, the rights under the rights plan.
However, if, prior to exchange, the rights have separated from the Common Stock in accordance with the provisions of the applicable
rights plan, the Exchange Rate will be adjusted at the time of separation as if the General Partner distributed to all or substantially
all holders of the Common Stock, shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants
as described in Section 13.04(c) hereof, subject to readjustment in the event of the expiration, termination or redemption of such
rights. 


 


(i) Deferral of Adjustments. Notwithstanding
anything to the contrary herein, except on and after the first Trading Day of any Cash Settlement Averaging Period with respect
to a Note and on or prior to the last Trading Day of such Cash Settlement Averaging Period, the Issuer will not be required to
adjust the Exchange Rate unless such adjustment would require an increase or decrease of at least one percent; provided,
however, that any such minor adjustments that are not required to be made will be carried forward and taken into account
in any subsequent adjustment, and provided, further, that any such adjustment of less than one percent that has not
been made shall be made upon the occurrence of (i) the Effective Date for any Make-Whole Fundamental Change, (ii) the first Trading
Day of any Cash Settlement Averaging Period and (iii) if the Issuer elects to satisfy its Exchange Obligation solely in shares
of Common Stock, upon any exchange of Notes. In addition, the Issuer shall not account for such deferrals when determining what
number of shares of Common Stock a Holder would have held on a given day had it exchanged its Notes.


 




    	63



     


    

 


(i) Limitation on Adjustments. Except
as stated in this Section 13.04, the Issuer will not adjust the Exchange 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 the Common Stock or such
convertible or exchangeable securities. If, however, the application of the formulas in Sections 13.04(a) through (e) hereof would
result in a decrease in the Exchange Rate, then, except to the extent of any readjustment to the Exchange Rate, no adjustment to
the Exchange Rate will be made (other than as a result of a reverse share split, share combination or readjustment). 


 


Notwithstanding anything to the contrary
herein, the Exchange Rate will not be adjusted:


 


		(1)	on account of stock repurchases that are not tender offers
referred to in Section 13.04(e) hereof, including structured or derivative transactions, or transactions pursuant to a stock repurchase
program approved by the Board of Directors or otherwise;



 


		(2)	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 Issuer’s or the General
Partner’s securities and the investment of additional optional amounts in shares of Common Stock under any plan;



 


		(3)	upon the issuance of any shares of Common Stock or options
or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan, program or
agreement of or assumed by the Issuer, the General Partner or any of their subsidiaries;



 


		(4)	upon the issuance of any shares of Common Stock pursuant
to any option, warrant, right or exercisable, exchangeable or convertible security not described in the preceding clause (3) and
outstanding as of the date the Notes were first issued;



 


		(5)	for a change in the par value of the Common Stock;



 


		(6)	for accrued and unpaid interest on the Notes, if any; or



 


		(7)	for an event otherwise requiring an adjustment under this
Indenture if such event is not consummated.



 


(j) For purposes of this Section 13.04,
the number of shares of Common Stock at any time outstanding shall not include shares of Common Stock held in the treasury of the
General Partner so long as the General Partner does not pay any dividend or make any distribution on shares of Common Stock held
in the treasury of the General Partner.


 


(k) Whenever the Issuer is required to calculate
the Exchange Rate, or any adjustment thereto, the Issuer will do so to the nearest 1/10,000th of a share of Common Stock.


 




    	64



     


    

 


Section 13.05 Discretionary and Voluntary Adjustments.



 


(a) Discretionary Adjustments. Whenever
any provision of this Indenture requires the Issuer to calculate the Last Reported Sale Prices, the Daily VWAPs or any function
thereof over a span of multiple days (including, without limitation, during a Cash Settlement Averaging Period), the Board of Directors
will make appropriate adjustments to each to account for any adjustment to the Exchange Rate that becomes effective, or any event
requiring an adjustment to the Exchange Rate where the Effective Date, Ex-Dividend Date or Expiration Date of the event occurs,
at any time during the period when such Last Reported Sale Prices, the Daily VWAPs or function thereof is to be calculated. For
the avoidance of doubt, the trustee and exchange agent shall not be responsible for calculating any of the calculations specified
above.


 


(b) Voluntary Adjustments. In addition
to those adjustments required by Sections 13.04(a) through (e) hereof, and to the extent permitted by applicable law and subject
to the applicable rules of the NYSE or any other securities exchange or market on which the Common Stock is then listed, the Issuer
from time to time may increase the Exchange Rate 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 Issuer’s best interest. In addition, to the extent permitted by applicable
law and subject to the applicable rules of the NYSE or any other securities exchange or market on which the Common Stock is then
listed, the Issuer may (but is not required to) increase the Exchange Rate to avoid or diminish any income tax to holders of Common
Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights to
acquire shares of Common Stock) or similar event. Whenever the Exchange Rate is increased pursuant to either of the preceding two
sentences, the Issuer shall deliver to the Holder of each Note a notice of the increase at least 15 days prior to the date the
increased Exchange Rate takes effect, and such notice shall state the increased Exchange Rate and the period during which it will
be in effect. 


 


Section 13.06 Adjustment to Exchange Rate Upon Exchange
in Connection with a Make-Whole Fundamental Change. 


 


(a) Increase in the Exchange Rate.
If a Make-Whole Fundamental Change occurs and a Holder elects to exchange its Notes in connection with such Make-Whole Fundamental
Change, the Issuer shall, under certain circumstances, increase the Exchange Rate for the Notes so surrendered for exchange by
a number of additional shares of Common Stock (the “Additional Shares”), as described in this Section 13.06.
An exchange of Notes shall be deemed for these purposes to be “in connection with” a Make-Whole Fundamental Change
if the relevant Exchange Notice is received by the Exchange Agent during the period from, and including, the Effective Date of
the Make-Whole Fundamental Change up to, and including, the Close of Business on the Business Day immediately prior to the related
Fundamental Change Repurchase Date or, if such Make-Whole Fundamental Change is not a Fundamental Change, the 35th Business Day
immediately following the Effective Date for such Make-Whole Fundamental Change.


 


(b) Cash Mergers. Notwithstanding
anything to the contrary herein, if the consideration paid to holders of the Common Stock in any Make-Whole Fundamental Change
described in clause (2) of the definition of Fundamental Change is comprised entirely of cash, then, for any exchange of Notes
following the Effective Date of such Make-Whole Fundamental Change, the Settlement Amount 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 exchanged Notes equal
to the applicable Exchange Rate (including any adjustment for Additional Shares as described in this Section 13.06), multiplied
by such Stock Price. In such event, the Issuer will pay such amount of cash to an exchanging Holder on the third Business Day
following the applicable Exchange Date. Otherwise, the Issuer will settle any exchange of Notes following the Effective Date for
a Make-Whole Fundamental Change in accordance with Section 13.04 hereof (but subject to Section 13.07 hereof). 


 


(c) Determining the Number of Additional
Shares. The number of Additional Shares, if any, by which the Exchange Rate will be increased for a Holder that exchanges its
Notes in connection with a Make-Whole Fundamental Change shall be determined by reference to the table attached as Schedule
A hereto, 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 paid) per share of the Common Stock in the
Make-Whole Fundamental Change. If the holders of the Common Stock receive only cash in a Make-Whole Fundamental Change described
in clause (2) 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 10 consecutive Trading Day period
ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change.


 




    	65



     


    

 


(d) Interpolation and Limits. The
exact Stock Prices and Effective Dates may not be set forth in the table attached as Schedule A, in which case: 


 


		(1)	if the Stock Price is between two Stock Prices in the table
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, as applicable, based on a 365-day year;



 


		(2)	if the Stock Price is greater than $170.00 per share (subject
to adjustment in the same manner as the Stock Prices set forth in the column headings of the table attached as Schedule A
pursuant to subsection (e) below), no additional shares will be added to the Exchange Rate; or



 


		(3)	if the Stock Price is less than $60.50 per share (subject
to adjustment in the same manner as the Stock Prices set forth in the column headings of the table attached as Schedule A
pursuant to subsection (e) below), no additional shares will be added to the Exchange Rate.



 


Notwithstanding the foregoing, in no event
will the Exchange Rate be increased on account of a Make-Whole Fundamental Change to exceed 16.52888 shares of Common Stock per
$1,000 principal amount of Notes, subject to adjustments in the same manner as the Exchange Rate is required to be adjusted as
set forth in Section 13.05 hereof.


 


(e) Adjustments to Stock Prices. The
Stock Prices set forth in the column headings of the table attached as Schedule A hereto shall be adjusted as of any date
on which the Exchange Rate of the Notes is otherwise required to be 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 Exchange Rate immediately
prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Exchange Rate as so adjusted.
The number of Additional Shares set forth in such table shall be adjusted in the same manner and at the same time as the Exchange
Rate is required to be adjusted as set forth in Section 13.04. The Trustee and the Exchange Agent shall not be responsible for
calculating any of the calculations set forth above.


 


Section 13.07. Effect of Recapitalization, Reclassification,
Consolidation, Merger or Sale.


 


(a) In the case of:


 


		(1)	any recapitalization, reclassification or change of the
Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a
result of a split, subdivision or combination for which an adjustment is made pursuant to Section 13.04(a));



 


		(2)	any consolidation, merger or combination involving the
Issuer or the General Partner;



 


		(3)	any sale, lease or other transfer to a third party of the
consolidated assets of the Issuer, the General Partner and their Subsidiaries substantially as an entirety; or



 




    	66



     


    

 


		(4)	any statutory share exchange;



 


and, in each case, as a result of which the 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 the Merger Event, the right to
exchange each $1,000 principal amount of Notes shall be changed into a right to exchange 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 Exchange Rate immediately prior to such Merger Event would have owned
or been entitled to receive upon such Merger Event (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 is entitled to
receive) and, prior to or at the effective time of such Merger Event, the Issuer or the successor or purchasing Person, as the
case may be, shall execute with the Trustee a supplemental indenture permitted under ‎Section 9.01 providing for such change
in the right to exchange each $1,000 principal amount of Notes; provided, however, that at and after the effective
time of the Merger Event (A) the Issuer shall continue to have the right to determine the form of consideration to be paid or delivered,
as the case may be, upon exchange of Notes in accordance with ‎Section 13.02 and (B) (i) any amount payable in cash upon exchange
of the Notes in accordance with ‎Section 13.02 shall continue to be payable in cash, (ii) any shares of Common Stock that the
Issuer would have been required to deliver upon exchange of the Notes in accordance with ‎Section 13.02 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 exchangeable shall be deemed
to be (x) the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively
make such an election or (y) if no holders 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
of the Common Stock receive only cash in such Merger Event, then for all exchanges for which the relevant Exchange Date occurs
after the effective date of such Merger Event (A) the consideration due upon conversion of each $1,000 principal amount of
Notes shall be solely cash in an amount equal to the Exchange Rate in effect on the Exchange Date (as may be increased by any Additional
Shares pursuant to ‎Section 13.06), multiplied by the price paid per share of Common Stock in such Merger Event and (B) the
Issuer shall satisfy the Exchange Obligation by paying cash to exchanging Holders on the third Business Day immediately following
the relevant Exchange Date. The Issuer shall notify Holders, the Trustee and the Exchange Agent (if other than the Trustee) of
such weighted average as soon as practicable after such determination is made.


 


Such supplemental indenture described in
the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly equivalent
as is possible to the adjustments provided for in this Article 13. 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 of the foregoing) of a Person
other than the successor or purchasing Person, 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.


 




    	67



     


    

 


(b) When the Issuer executes a supplemental
indenture pursuant to subsection ‎(a) of this ‎Section 13.07, the Issuer shall promptly file with the Trustee an Officers’
Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise
a unit of 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 deliver notice thereof to all Holders. The Issuer shall cause notice of the
execution of such supplemental indenture to be delivered to each Holder within 20 days after execution thereof. Failure to deliver
such notice shall not affect the legality or validity of such supplemental indenture. Any such supplemental indenture filed with
the Commission through the EDGAR system (or any successor thereto) shall be deemed to have been sent to the Holders for purposes
of this Section 13.07.


 


(c) The Issuer shall not become a party
to any Merger Event unless its terms are consistent with this ‎Section 13.07. None of the foregoing provisions shall affect
the right of a holder of Notes to exchange 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 13.01 and ‎Section 13.02 prior to the effective date of such Merger Event.


 


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


 


Section 13.08. Ownership Limit and Withholding.


 


(a) Notwithstanding any other provision
of the Notes or this Indenture, no Holder of Notes will be entitled to receive Common Stock following exchange of such Notes to
the extent that receipt of such Common Stock would cause such Holder (after application of certain constructive ownership rules)
to exceed the ownership limits contained in the General Partner’s charter. If any delivery of shares of Common Stock owed
to a Holder upon exchange of Notes is not made, in whole or in part, as a result of the limitations described in this Section 13.08(a),
the Issuer’s obligation to make such delivery shall not be extinguished and the Issuer shall deliver such shares as promptly
as practicable after any such exchanging Holder gives notice to the Issuer that such delivery would not result in it being the
beneficial or constructive owner of (i) more than 9.8% in value of the General Partner’s outstanding shares of Capital Stock,
or (ii) more than 9.8% in value or in number of shares, whichever is more restrictive, of the General Partner’s outstanding
Common Stock.


 


(b) At the Maturity Date, upon earlier repurchase
of the Notes or at any time a payment is made with respect to the Notes, and as otherwise required by law, the Issuer may deduct
and withhold from such amount otherwise deliverable to the Holder the amount required to be deducted and withheld under applicable
law, and such amount shall be deemed paid to such Holder for all purposes of this Indenture.


 


Section 13.09. Calculations in Respect of Notes.


 


Except as otherwise provided in this Indenture,
the Issuer shall be responsible for making all calculations called for under the Notes and this Indenture. These calculations include,
but are not limited to, determinations of the Last Reported Sale Prices of the Common Stock, accrued interest payable on the Notes
and the Exchange Rate of the Notes (including any adjustments thereto). The Issuer shall make all these calculations in good faith
and, absent manifest error, the Issuer’s calculations shall be final and binding on Holders of Notes. The Issuer shall provide
a schedule of its calculations to each of the Trustee and the Exchange Agent, and each of the Trustee and Exchange Agent is entitled
to rely conclusively upon the accuracy of the Issuer’s calculations without independent verification and neither shall have
any liability or responsibility for the calculations or any information used to make such calculations. The Trustee will forward
the Issuer’s calculations to any Holder of Notes upon the request of that Holder at the sole cost and expense of the Issuer.
Neither the Trustee nor the Exchange Agent shall be responsible for determining whether any event has occurred that would cause
an adjustment to the Exchange Rate. The Issuer shall deliver a notice to the Trustee and the Exchange Agent with respect to any
Exchange Rate adjustment, on which notice the Trustee and the Exchange Agent may conclusively rely.

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 Notes affected thereby:


 


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



 


		(2)	the principal amount of the outstanding Notes 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 14.05. Determination of Voting Rights; Conduct
and Adjournment of Meetings.

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 Notes shall be proved in the manner specified in Section 8.01 and the appointment of any proxy shall be proved in
the manner specified in Section 8.01 or by having the signature of the Person executing the proxy witnessed or guaranteed by any
trust company, bank or banker authorized by Section 8.01 to certify to the holding of the Notes. 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 8.01 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 Issuer, the General Partner
or by Holders of Notes as provided in Section 14.02(b), in which case the Issuer, the General Partner or the Holders of Notes calling

or proxy shall be entitled to one vote for each $1,000 principal amount of the outstanding Notes held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any Note 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

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 Notes 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 14.02 and, if applicable, Section 14.04.
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 Issuer and the General Partner 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.

Section 15.01. Guarantees. 


 


(a) By its execution hereof, each Guarantor
acknowledges that it receives substantial benefits from the Issuer and that the Guarantors are providing their Guarantees for good
and valuable consideration, including, without limitation, such substantial benefits. Accordingly, subject to the provisions of
this Article 15, each Guarantor hereby fully, unconditionally and irrevocably guarantees, as primary obligor and not merely as
surety, jointly and severally with each other Guarantor, to each Holder of the Notes, to the extent lawful, and the Trustee the

after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, relating
to the Issuer or any Guarantor whether or not a claim for post-filing or post-petition interest is allowed in such proceeding)
(all the foregoing being hereinafter collectively called the “Guarantor Obligations”). Each Guarantor agrees
(to the extent lawful) that the Guarantor Obligations may be extended or renewed, in whole or in part, without notice or further
assent from it, and that it shall remain bound under this Article 15 notwithstanding any extension or renewal of any Guarantor
Obligation.


 


(b) Each Guarantor waives (to the extent
lawful) presentation to, demand of, and protest to the Issuer of any of the Guarantor Obligations and also waives (to the extent
lawful) notice of protest for nonpayment. Each Guarantor waives (to the extent lawful) notice of any default under the Notes or
the Guarantor Obligations.


 


(c) Each Guarantor further agrees that its
Guarantee constitutes a guarantee of payment when due (and not a guarantee of collection) and waives any right to require that
any resort be had by any Holder to any security held for payment of the Guarantor Obligations.


 




    	71



     


    

 


(d) The obligations of each Guarantor hereunder
shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Guarantor
Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not (to the extent
lawful) be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity,
illegality or unenforceability of the Guarantor Obligations or otherwise. Without limiting the generality of the foregoing, the
obligations of each Guarantor herein shall not (to the extent lawful) be discharged or impaired or otherwise affected by


 


		(1)	the failure of any Holder to assert any claim or demand
or to enforce any right or remedy against the Issuer or any other person under this Indenture, the Notes or any other agreement
or otherwise;



 


		(2)	any extension or renewal of any thereof;



 


		(3)	any rescission, waiver, amendment or modification of any
of the terms or provisions of this Indenture (other than the terms of this Guarantee), the Notes or any other agreement;



 


		(4)	the release of any security held by any Holder or the Trustee
for the Guarantor Obligations or any of them;



 


		(5)	the failure of any Holder to exercise any right or remedy
against any other Guarantor;



 


		(6)	any change in the ownership of the General Partner or the
Issuer;



 


		(7)	any default, failure or delay, willful or otherwise, in
the performance of the Guarantor Obligations; or



 


		(8)	any other act or thing or omission or delay to do any other
act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a
discharge of such Guarantor as a matter of law or equity.



 


(e) Each Guarantor agrees that its Guarantee
shall remain in full force and effect until payment in full of all the Guarantor Obligations or such Guarantor is released from
its Guarantee in compliance with Section 15.03. Each Guarantor further agrees that its Guarantee shall continue to be effective
or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of, premium, if any, or interest
on any of the Guarantor Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization
of the General Partner or the Issuer or otherwise.


 


(f) In furtherance of the foregoing and
not in limitation of any other right which any Holder has at law or in equity against any Guarantor by virtue hereof, upon the
failure of the Issuer to pay any of the Guarantor Obligations when and as the same shall become due, whether at maturity, by acceleration,
upon repurchase due to a Fundamental Change or otherwise, each Guarantor hereby promises to and shall, upon receipt of written
demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Trustee or the Trustee on behalf of the Holders an amount
equal to the sum of (i) the unpaid amount of such Guarantor Obligations then due and owing and (ii) accrued and unpaid interest
on such Guarantor Obligations then due and owing (but only to the extent not prohibited by law) (including interest accruing after
the filing of any petition in bankruptcy or the commencement of any insolvency, reorganization or like proceeding relating to the
Issuer or any Guarantor whether or not a claim for post-filing or post-petition interest is allowed in such proceeding).


 




    	72



     


    

 


(g) Each Guarantor further agrees that,
as between such Guarantor, on the one hand, and the Holders, on the other hand, (i) the maturity of the Guarantor Obligations guaranteed
hereby may be accelerated as provided in this Indenture for the purposes of its Guarantee, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the Guarantor Obligations guaranteed and (ii) in the event of any
such declaration of acceleration of such Guarantor Obligations, such Guarantor Obligations (whether or not due and payable) shall
forthwith become due and payable by the Guarantors for the purposes of such Guarantors’ Guarantee.


 


(h) Each Guarantor also agrees to pay any
and all reasonable costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or the Holders in enforcing
any rights under this Section 15.01.


 


(i) Neither the Issuer nor the Guarantors
shall be required to make a notation on the Notes to reflect any Guarantee or any release, termination or discharge thereof and
any such notation shall not be a condition to the validity of any Guarantee.


 


Section 15.02. Additional Guarantees.


 


If the Issuer or any Subsidiary Guarantor acquires or creates
a Subsidiary, then such Subsidiary shall become a Subsidiary Guarantor and execute a supplemental indenture in the form attached
as Attachment 1 to the Form of Note attached as Exhibit A hereto, and deliver (i) an Opinion of Counsel and (ii) an Officers’
Certificate satisfying the requirements of this Indenture within 45 days following the date on which it was acquired, created
or otherwise became a Subsidiary (or such longer period as may be required to obtain any necessary approvals under applicable laws
or other regulatory requirements). The General Partner and the Issuer shall use commercially reasonable efforts to obtain all approvals
necessary to permit any Subsidiary to become a Subsidiary Guarantor as promptly as practicable.


 


Section 15.03. Limitation on Liability; Termination, Release
and Discharge.


 


(a) Any term or provision of this Indenture
to the contrary notwithstanding, the obligations of each Guarantor hereunder shall be limited to the maximum amount as shall, 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 its contribution obligations under this Indenture, result in the obligations of such Guarantor under its Guarantee
not constituting a fraudulent conveyance or fraudulent transfer under federal or state law and not otherwise being void or voidable
under any similar laws affecting the rights of creditors generally.


 


(b) A Guarantee of a Guarantor shall be
automatically and unconditionally released and discharged, and each Guarantor and its obligations under the Guarantee and this
Indenture shall be released and discharged:


 


		(1)	in connection with any sale or other disposition of all
or substantially all of the assets of that Guarantor (by way of merger, consolidation, or otherwise) to a Person that is not (either
before or after giving effect to such transaction) the General Partner, the Issuer or a Subsidiary Guarantor;



 


		(2)	in connection with any sale or other disposition of Capital
Stock of that Guarantor to a Person that is not (either before or after giving effect to such transaction) the General Partner,
the Issuer or a Subsidiary Guarantor; or



 


		(3)	satisfaction and discharge of this Indenture pursuant to
Article 11 of this Indenture.



 




    	73



     


    

 


Section 15.04. Right of Contribution. 


 


(a) Each Guarantor agrees that in the event
any payment or distribution is made by any Guarantor (a “Funding Guarantor”) in respect of the Guarantor Obligations,
such Funding Guarantor shall be entitled to a contribution from each other Guarantor in a pro rata amount based on the relative
net worth of each Guarantor (including the Funding Guarantor) as of the date of such payment or distribution for all payments,
damages and expenses incurred by that Funding Guarantor in discharging the Guarantor Obligations. The provisions of this Section 15.04
shall in no respect limit the obligations and liabilities of each Guarantor to the Trustee and the Holders and each Guarantor shall
remain liable to the Trustee and the Holders for the full amount guaranteed by such Guarantor hereunder.


 


(b) Any request, direction, order or demand
which by any provision of this Indenture is to be made by the Guarantors shall be sufficient if evidenced as described in Section
16.03 hereof as if references therein to the Issuer were references to the Guarantors.


 


(c) Any notice or demand which by any provision
of this Indenture is required or permitted to be given or served by the Trustee or by the Holders of Notes to or on the Guarantors
may be given or served as described in Section 16.03 hereof as if references therein to the Issuer were references to the Guarantors.


 


(d) Upon any demand, request or application
by the Guarantors to the Trustee to take any action under this Indenture, the Guarantors shall furnish to the Trustee such certificates
and opinions as are required in Section 16.05 hereof as if all references therein to the Issuer were references to the Guarantors.


 


Section 15.05. No Subrogation.


 


Notwithstanding any payment or payments
made by any Guarantor hereunder, no Guarantor shall be entitled to be subrogated to any of the rights of the Trustee or any Holder
against the Issuer or any other Guarantor or any collateral security or guarantee or right of offset held by the Trustee or any
Holder for the payment of the Guarantor Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement
from the Issuer or any other Guarantor in respect of payments made by such Guarantor hereunder, until the Guarantor Obligations
are paid in full. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the
Guarantor Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Trustee and
the Holders, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over
to the Trustee in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Trustee, if required), to be
applied against the Guarantor Obligations.

This Note is one of a duly authorized issue of securities of
the Issuer (herein called the “Notes”), issued under an Indenture dated as of February 21, 2019 (herein
called the “Indenture”) by and among the Issuer, the guarantors party thereto and GLAS Trust Company LLC, herein
called the “Trustee”, and reference is hereby made to the Indenture for a statement of the respective rights,
limitations of rights, duties and immunities thereunder of the Issuer, the Trustee and the Holders of the Notes and of the terms
upon which the Notes are, and are to be, authenticated and delivered. This Note is not subject to redemption at the option of the
Issuer prior to the Maturity Date and does not benefit from a sinking fund.


 


As provided in and subject to the provisions of the Indenture,
upon the occurrence of a Fundamental Change, the Holder of this Note will have the right, at such Holder’s option, to require
the Issuer to purchase this Note, or any portion of this Note such that the principal amount of this Note that is not purchased
equals $1,000 or an integral multiple of $1,000 in excess thereof, on the Fundamental Change Repurchase Date at a price equal to
the Fundamental Change Repurchase Price for such Fundamental Change Repurchase Date.


 


As provided in and subject to the provisions of the Indenture,
the Holder hereof has the right, at any time prior to the Close of Business on the second Scheduled Trading Day immediately preceding
the Maturity Date, to exchange this Note or a portion of this Note such that the principal amount of this Note that is not exchanged
equals $1,000 or an integral multiple of $1,000 in excess thereof, into shares of Common Stock in accordance with Article 13
of the Indenture.


 


As provided in and subject to the provisions of the Indenture,
the Issuer will make all payments in respect of the Fundamental Change Repurchase Price for, and the principal amount of, this

notice of a continuing Event of Default with respect to the Note, the Holders of not less than 25% in principal amount of the Notes
at the time outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default
as Trustee and offered the Trustee indemnity, and the Trustee shall not have received from the Holders of a majority in principal
amount of Notes at the time outstanding a direction inconsistent with such request, and shall have failed to institute any such
proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit
instituted by the Holder of this Note for the enforcement of any payment of principal hereof or interest hereon or amounts due
upon exchange on or after the respective due dates expressed herein.
