 ERP OPERATING LIMITED PARTNERSHIP 

4.000% Notes due August 1, 2047 

ERP Operating Limited Partnership, an Illinois limited partnership (the “Issuer,” which term includes any successor under the
Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co. or registered assigns, the principal sum of Three Hundred Million Dollars on August 1, 2047 (the “Maturity Date”), and to pay
interest thereon from August 3, 2017 (or from the most recent Interest Payment Date to which interest has been paid or duly provided for), semi annually in arrears on February 1 and August 1 of each year (each, an “Interest
Payment Date”), commencing on February 1, 2018, and on the Maturity Date, at the rate of 4.000% per annum, until payment of said principal sum has been made or duly provided for. 

The interest so payable and punctually paid or duly provided for on any Interest Payment Date and on the Maturity Date will be paid to the
Holder in whose name this Note (or one or more predecessor Notes) is registered at the close of business on the “Record Date” for such payment, which will be the January 15 or July 15 next preceding such Interest Payment Date, or
the Maturity Date, as the case may be. Any interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Record Date, and shall be paid to the Holder in whose name this Note (or one or more
predecessor Notes) is registered at the close of business on a subsequent record date for the payment of such defaulted interest (which shall be not more than 15 days and not less than 10 days) prior to the date of the payment of such defaulted
interest) established by notice given by mail by or on behalf of the Issuer to the Holders of the Notes not less than ten days preceding such subsequent record date. Interest on this Note will be computed on the basis of a 360-day year of twelve 30-day months. 
 The principal of this
Note payable on the Maturity Date will be paid against presentation and surrender of this Note at the office or agency of the Issuer maintained for that purpose in the Borough of Manhattan, the City of New York. The Issuer hereby initially
designates the Corporate Trust Office of the Trustee in the City of Chicago, and the office or agency of the Trustee in the Borough of Manhattan, the City of New York, as the offices to be maintained by it where Notes may be presented for payment,
registration of transfer or exchange and where notices or demands to or upon the Issuer in respect of the Notes or the Indenture referred to on the reverse hereof may be served. 

Interest payable on this Note on any Interest Payment Date and on the Maturity Date, as the case may be, will be the amount of interest
accrued from and including the immediately preceding Interest Payment Date (or from and including August 3, 2017, in the case of the initial Interest Payment Date) to but excluding the applicable Interest Payment Date or the Maturity Date, as
the case may be. If any Interest Payment Date other than the Maturity Date would otherwise be a day that is not a Business Day (as defined below), such Interest Payment Date will be postponed to 

 
the succeeding Business Day. If the Maturity Date falls on a day that is not a Business Day, principal and interest payable on the Maturity Date will be paid on the succeeding Business Day with
the same force and effect as if it were paid on the date such payment was due, and no interest will accrue on the amount so payable for the period from and after the Maturity Date. “Business Day” means any day, other than a Saturday or
Sunday, that is neither a legal holiday nor a day on which banking institutions in the City of New York or the City of Chicago are authorized or required by law, regulation or executive order to close. 

Payments of principal and interest in respect of this Note will be made to the registered Holder of this Note in such coin or currency as at
the time of payment is legal tender for the payment of public and private debts. 
 Reference is made to the further provisions of this Note
set forth on the reverse hereof. Such further provisions shall for all purposes have the same effect as though fully set forth at this place. 

This Note shall not be entitled to the benefits of the Indenture referred to on the reverse hereof or be valid or become obligatory for any
purpose until the certificate of authentication hereon shall have been signed by the Trustee under such Indenture.

 IN WITNESS WHEREOF, the Issuer has caused this instrument to be signed manually or by facsimile

 [REVERSE OF NOTE] 

ERP OPERATING LIMITED PARTNERSHIP 

4.000% Notes due August 1, 2047 

This Note is one of a duly authorized issue of debentures, notes, bonds, or other evidences of indebtedness of the Issuer (hereinafter called
the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to (i) an Indenture dated as of October 1, 1994 as supplemented from time to time (herein called the “Indenture”),
duly executed and delivered by the Issuer to The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust Company, N.A.) (as successor to J.P. Morgan Trust Company, National Association, as successor to Bank One
Trust Company, N.A., as successor to The First National Bank of Chicago) as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture with respect to the series of Securities of which this Note is
a part), and (ii) an Officers’ Certificate dated the date hereof (the “Officers’ Certificate”), duly executed by authorized officers of the Issuer, pursuant to Section 301 of the Indenture to which Officers’
Certificate and Indenture and all Indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties, and immunities thereunder of the Trustee, the Issuer, and the Holders of the
Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at
different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), and may otherwise vary as provided in the Indenture. This Note is one of a series designated as the 4.000% Notes due
August 1, 2047 of the Issuer (the “Notes”). Subject to being increased by the Issuer pursuant to an Officers’ Certificate, the Notes are limited in aggregate principal amount to $300,000,000 (except as provided in the Indenture).

 If an Event of Default with respect to the Notes occurs and is continuing, the principal hereof and Make-Whole Amount (if any) may be
declared, and upon such declaration shall become, due and payable, in the manner, with the effect, and subject to the conditions provided in the Indenture. 

Prior to February 1, 2047, the Issuer may redeem the Notes, at any time in whole or from time to time in part, at the election of the
Issuer, at a redemption price equal to the sum of (i) the principal amount of the Notes being redeemed plus accrued interest thereon to the Redemption Date and (ii) the Make-Whole Amount, if any, with respect to the Notes. For purposes of
the Notes, the Reinvestment Rate will be determined using 0.200% as specified in the Officers’ Certificate in lieu of the percentage contained in the Indenture. On or after February 1, 2047, the Issuer may redeem the Notes, at any time in
whole or from time to time in part, at the election of the Issuer, at a redemption price equal to the principal amount of the Notes being redeemed plus accrued interest thereon to the Redemption Date. Notice of any optional redemption of any Notes
will be given to Holders at their addresses, as shown in the Security Register, not more than 45 nor less than 15 days prior to the date fixed for redemption. The notice of redemption will specify, among other items, the redemption price and the
principal amount of the Notes held by such Holder to be redeemed. 
 The Indenture contains provisions for defeasance of (i) the entire
indebtedness of the Notes or (ii) certain covenants (specifically including the covenants in the third supplemental indenture dated as of June 4, 2007, by and between the Issuer and the Trustee, as modified by the fourth supplemental
indenture dated as of December 12, 2011, by and between the Issuer and the Trustee) and events of default with respect to the Notes in the Indenture in each case upon compliance with Article Fourteen of the Indenture, which provisions apply to
the Notes. 
 The Indenture contains provisions permitting the Issuer and the Trustee, with the consent of the Holders of not less than a
majority of the aggregate principal amount of all Outstanding Securities affected by such supplemental indenture, to execute supplemental Indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the
Indenture or modifying in any manner the rights of the Holders of Securities under the Indenture; provided, however, that no such supplemental Indenture shall, without the consent of the Holder of each Outstanding Security so affected,
(i) change the stated maturity of the principal of (or premium, if any), or any installment of principal of or interest on, any Security, (ii) reduce the principal amount of, or the rate or amount of interest on, or premium payable upon
the redemption of, any Security, (iii) change the place of payment, or the currency, for payment of principal of any Security or any premium or interest on any Security, (iv) impair the right to institute suit for the

 
enforcement of any payment on or with respect to any Security on or after the stated maturity thereof (or in the case of redemption, on or after the redemption date), (v) reduce the above-stated
percentage of Outstanding Securities of any series necessary to modify or amend the Indenture, to waive compliance with certain provisions thereof or certain defaults and consequences thereunder or to reduce the quorum or voting requirements set
forth in the Indenture, or (vi) modify any of the foregoing provisions or any provisions relating to the waiver of certain past defaults or certain covenants, except to increase the required percentage to effect such action or to provide that
certain other provisions may not be modified or waived without the consent of the Holders or each Outstanding Security affected thereby. It is also provided in the Indenture that, with respect to certain defaults or Events of Default regarding the
Securities of any series, the Holders of not less than a majority in aggregate principal amount outstanding of the Securities of such series may on behalf of the Holders of all the Securities of such series waive any such past default or Event of
Default and its consequences, prior to any declaration accelerating the maturity of such Securities; or, subject to certain conditions, may rescind a declaration of acceleration and its consequences with respect to such Securities. Any such consent
or waiver by the Holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Note and any securities that may be issued in exchange or substitution
herefor, irrespective of whether or not any notation thereof is made upon this Note or such other securities. 
 No reference herein to the
Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and any Make-Whole Amount and interest on this Note in the manner, at the
respective times, at the rate and in the coin or currency herein prescribed. 
 This Note is issuable only in registered form without
coupons in denominations of $1,000 and integral multiples thereof. Securities may be exchanged for a like aggregate principal amount of Securities of this series of other authorized denominations at the office or agency of the Issuer maintained for
that purpose at the Corporate Trust Office of the Trustee in the City of Chicago, and the office or agency of the Trustee in the Borough of Manhattan, the City of New York, in the manner and subject to the limitations provided in the Indenture, but
without the payment of any service charge except for any tax or other governmental charge imposed in connection therewith. 
 Upon due
presentment for registration of transfer of Securities at the office or agency of the Issuer maintained for that purpose at the Corporate Trust Office of the Trustee in the City of Chicago, or the office or agency of the Trustee in the Borough of
Manhattan, the City of New York, a new Security or Securities of the same series of authorized denominations in an equal aggregate principal amount will be issued to the transferee in exchange therefor, subject to the limitations provided in the
Indenture, without charge except for any tax or other governmental charge imposed in connection therewith. 
 The Issuer, the Trustee, and
any authorized agent of the Issuer or the Trustee may deem and treat the Person in whose name this Note is registered as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or
other writing hereon), for the purpose of receiving payment of, or on account of, the principal hereof and Make-Whole Amount, if any, and subject to the provisions on the face hereof, interest hereon, and for all other purposes, and neither the
Issuer nor the Trustee nor any authorized agent of the Issuer or the Trustee shall be affected by any notice to the contrary. 
 The
Indenture and each Security shall be deemed to be a contract under the laws of the State of New York, and for all purposes shall be governed by and construed in accordance with the law of the State of New York. 

Terms used herein that are defined in the Indenture shall have the respective meanings assigned thereto in the Indenture.Exhibit 4.1

(other than ordinary working capital borrowings) or issues, repurchases or redeems Preferred Stock subsequent to the commencement

Person. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar
rate, a Eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or
if none, then based upon such optional rate chosen as such Person may designate.

and including increases in ownership of Restricted Subsidiaries, during the four-quarter reference period or subsequent to such
reference period and on or prior to the Calculation Date, or that are to be made on the Calculation Date, will be given pro forma
effect as if they had occurred on the first day of the four-quarter reference period, and the Consolidated Cash Flow for such reference
period will be calculated giving pro forma effect to any expense and cost reductions or synergies that have occurred or are reasonably
expected to occur, in the reasonable judgment the Issuer’s principal financial or accounting officer (regardless of whether
those cost savings or operating improvements could then be reflected in pro forma financial statements in accordance with Regulation
S-X promulgated under the Securities Act or any other regulation or policy of the Commission related thereto);

The terms and provisions contained in the
Notes will constitute, and are hereby expressly made, a part of this Indenture and the Issuer, the Guarantors and the Trustee,
by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However,
to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture

Section

At least one Officer must sign the Notes
for the Issuer by manual, facsimile or electronically transmitted signature.

 

If an Officer whose signature is on a Note
no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid.

 

A Note will not be valid until authenticated
by the manual signature of the Trustee. The signature will be conclusive evidence that the Note has been authenticated under this
Indenture.

 

The Trustee will, upon receipt of a written
order of the Issuer signed by an Officer of the Issuer (an “Authentication Order”), authenticate Notes for original
issue that may be validly issued under this Indenture, including any Additional Notes. The aggregate principal amount of Notes
outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Issuer pursuant to
one or more Authentication Orders, except as provided in Section 2.07 hereof.

 

The Trustee may appoint an authenticating
agent acceptable to the Issuer to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do

paying agent. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer will notify the Trustee
in writing of the name and address of any Agent not a party to this Indenture. If the Issuer fails to appoint or maintain another

Trust Company (“DTC”) to act as Depositary with respect to the Global Notes.

Section
2.04         Paying Agent to Hold Money in Trust.

 

The Issuer will require each Paying Agent
other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all
money held by the Paying Agent for the payment of principal of, or premium or interest, if any, on, the Notes, and will notify
the Trustee of any default by the Issuer in making any such payment. While any such default continues, the Trustee may require
a Paying Agent to pay all money held by it to the Trustee. The Issuer at any time may require a Paying Agent to pay all money held
by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or a Subsidiary) will have no
further liability for the money. If the Issuer or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust
fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating
to the Issuer, the Trustee will serve as Paying Agent for the Notes.

at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably
require of the names and addresses of the Holders of the Notes.

Trustee will authenticate Global Notes and Definitive Notes
in accordance with the provisions of Section 2.02
hereof.

 

(viii)      All
certifications, certificates and Opinions of Counsel required to be submitted to the Registrar
pursuant to this Section 2.06 to effect
a registration of transfer or exchange may be submitted by facsimile.

 

Section
2.07         Replacement Notes.

 

If any mutilated Note is surrendered to
the Trustee or the Issuer and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note,
the Issuer will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s
requirements are met. If required by the Trustee or the Issuer, an indemnity bond must be supplied by the Holder that is sufficient
in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any
loss that any of them may suffer if a Note is replaced. The Issuer may charge for its expenses in replacing a Note.

 

Every replacement Note is an additional
obligation of the Issuer and will be entitled to all of the benefits of this Indenture equally and proportionately with all other
Notes duly issued hereunder.

 

Section
2.08         Outstanding Notes.

 

The Notes outstanding at any time are all
the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions
in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this
Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding
because the Issuer or an Affiliate of the Issuer holds the Note; however, Notes held by the Issuer or a Subsidiary of the Issuer
shall not be deemed to be outstanding for purposes of Section 3.07(a) hereof.

 

If a Note is replaced pursuant to Section
2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held
by a protected purchaser.

 

If the principal amount of any Note is considered
paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

 

If the Paying Agent (other than the Issuer,
a Subsidiary or an Affiliate thereof) holds, by 10 a.m., New York City time, on a redemption date or maturity date, money sufficient
to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease
to accrue interest.

 

    	 	 56	 

     

    

 

Section
2.09         Treasury Notes.

 

In determining whether the Holders of the
required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or any Guarantor,
or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer
or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee
will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so
disregarded.

 

Notwithstanding anything in this Indenture
to the contrary, no Person shall be deemed or presumed to have any such controlling interest, or to be under common control of
any other Person with the Company or any Guarantor, solely as a result of such Person and/or such other Person being a Beneficial
Owner of more than 10% of the Issuer’s outstanding Voting Stock, unless such Person and/or such other Person (as determined
in good faith by the Board of Directors of the Issuer) has the power, directly or indirectly, to direct or cause the direction
of the management and policies of the Issuer, whether through the ownership of the Voting Stock of the Company, by contract, or
otherwise.

 

Section
2.10         Temporary Notes.

 

Until certificates representing Notes are
ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary
Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Issuer consider
appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuer will
prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes.

 

Holders of temporary Notes will be entitled
to all of the benefits of this Indenture.

 

Section
2.11         Cancellation.

 

The Issuer at any time may deliver Notes
to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange,
payment, replacement or cancellation and will destroy canceled Notes (subject to the record retention requirements of the Exchange
Act). Certification of the destruction of all canceled Notes will be delivered to the Issuer. The Issuer may not issue new Notes
to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

 

Section
2.12         Defaulted Interest.

 

If the Issuer defaults in a payment of interest
on the Notes, they will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted
interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and
in Section 4.01 hereof. The Issuer will notify the Trustee in writing of the amount of defaulted interest proposed to be
paid on each Note and the date of the proposed payment. The Issuer will fix or cause to be fixed each such special record date
and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for
such defaulted interest. At least 15 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) will provide a notice to Holders that states the special record date,
the related payment date and the amount of such interest to be paid.

Article
III.

REDEMPTION AND PREPAYMENT

 

Section
3.01         Notices to Trustee.

 

If the Issuer elects to redeem Notes pursuant
to the optional redemption provisions of Section 3.07 hereof, it must furnish to the Trustee, at least five Business Days
prior to the giving of notice of a redemption, an Officers’ Certificate setting forth:

 

(a)          the
clause of this Indenture pursuant to which the redemption shall occur;

 

(b)          the
redemption date;

 

(c)          the
principal amount of Notes to be redeemed; and

 

(d)          the
redemption price (if then determined and otherwise the method of determination).

 

Section
3.02         Selection of Notes to Be
Redeemed.

 

If less than all of the Notes are to be
redeemed at any time, the Trustee will select Notes for redemption on a pro rata basis (or, in the case of Notes issued in global
form pursuant to Article II hereof, by such method as DTC or its nominee or successor may require or, where such nominee
or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate)
unless otherwise required by law or applicable stock exchange or depositary requirements.

 

In the event of partial redemption by lot,
the particular Notes to be redeemed will be selected, unless otherwise provided herein, not less than 30 nor more than 60 days
prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption.

 

The Trustee will promptly notify the Issuer
in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount
thereof to be redeemed. Notes and portions of Notes selected will be in amounts of $1,000 or whole multiples of $1.00 in excess
thereof; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder
shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption
also apply to portions of Notes called for redemption.

 

    	 	 58	 

     

    

 

Section
3.03         Notice of Redemption.

 

At least 30 days but not more than 60 days
before a redemption date, the Issuer will mail or cause to be mailed, by first class mail, a notice of redemption to each Holder
whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior
to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this
Indenture pursuant to Article VIII or XI hereof.

 

The notice will identify the Notes to be
redeemed and will state:

 

(a)          the
redemption date;

 

(b)          the
redemption price (if then determined and otherwise the method of determination);

 

(c)          if
any Note is being redeemed in part, the portion of the principal
amount of such Note to be redeemed and that, after the redemption date upon surrender
of such Note, a new Note or Notes in principal amount
equal to the unredeemed portion will be issued in the name of the Holder
thereof upon cancellation of the original Note;

 

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

 

(e)          that
Notes called for redemption must be surrendered to the Paying
Agent to collect the redemption price;

 

(f)          that,
unless the Issuer defaults in making such redemption payment, interest on Notes
or portions thereof called for redemption ceases to accrue on and after the redemption date;

 

(g)          the
paragraph of the Notes and/or Section of this Indenture
pursuant to which the Notes called for redemption are being redeemed; and

 

(h)          that
no representation is made as to the correctness or accuracy of the CUSIP or
ISIN number, if any, listed in such notice or printed on the Notes.

 

At the Issuer’s request, the Trustee
will give the notice of redemption in the Issuer’s names and at the Issuer’s expense; provided, however,
that the Officers’ Certificate delivered to the Trustee pursuant to Section 3.01 hereof requests that the Trustee
give such notice and sets forth the information to be stated in such notice as provided in the preceding paragraph.

 

Section
3.04         Effect of Notice of Redemption.

 

Once notice of redemption is mailed in accordance
with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable (subject to the provisions of the
next succeeding sentence) on the redemption date at the redemption price. A notice of redemption may not be conditional, except
that any redemption pursuant to Section 3.07(a) may, at the Issuer’s discretion, be subject to completion of the related
Equity Offering.

 

    	 	 59	 

     

    

 

Section
3.05         Deposit of Redemption or Purchase
Price.

 

No later than 10:00 a.m., New York City
time, on the redemption or purchase date, the Issuer will deposit with the Trustee or with the Paying Agent money sufficient to
pay the redemption or purchase price of, and accrued interest, if any, on all Notes to be redeemed or purchased on that date. The
Trustee or the Paying Agent will promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the
Issuer in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest, if any, on all Notes
to be redeemed or purchased.

 

If the Issuer complies with the provisions
of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions
of Notes called for redemption or accepted for purchase. If a Note is redeemed or purchased on or after an interest record date
but on or prior to the related interest payment date, then any accrued and unpaid interest, if any, shall be paid to the Person
in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or tendered
for purchase is not so paid upon surrender for redemption or purchase because of the failure of the Issuer to comply with the preceding
paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and
to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes.

 

Section
3.06         Notes Redeemed or
Purchased in Part.

 

Upon surrender of a Note that is redeemed
or purchased in part, the Issuer will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the
Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

 

Section
3.07         Optional Redemption.

 

(a)          At
any time prior to February 15, 2020, the Issuer may on any one or
more occasions redeem up to 35% of the aggregate principal amount of Notes
issued under this Indenture, with an amount of cash not greater than the net cash
proceeds of an Equity Offering by the Issuer, upon notice as provided
in this Indenture, at a redemption price equal to 109.00%
of the principal amount of the Notes redeemed, plus
accrued and unpaid interest, if any, to the date of redemption (subject to the rights of
Holders on the relevant record date to receive interest on the relevant interest payment date), provided
that:

 

(1)         at

(2)         the
redemption occurs within 180 days of the date of the closing of such Equity Offering.

 

(b)          At
any time prior to February 15, 2020, the Issuer may on any one or
more occasions redeem all or a part of the Notes,
upon notice as provided in this Indenture, at a redemption
price equal to the sum of:

 

    	 	 60	 

     

    

 

(1)         100%
of the principal amount thereof, plus

 

(2)         the
Applicable Premium as of the redemption date,

 

plus accrued and unpaid interest, if any,
to the redemption date (subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest
payment date).

 

(c)          Except
pursuant to Section 3.07(a), (b) or (e),
the Notes will not be redeemable at the Issuer’s
option prior to February 15, 2020.

 

(d)          On
and after February 15, 2020, the Issuer may on any one or
more occasions redeem all or a part of the Notes,
upon notice as provided in this Indenture, at the
redemption prices (expressed as percentages of principal amount) set forth below, plus
accrued and unpaid interest, if any, on the Notes redeemed, to the applicable redemption
date, subject to the rights of Holders on the relevant record date to receive interest on the relevant
interest payment date, if redeemed during the twelve-month period beginning on February 15 of the years indicated below:

 

	Year	 	Percentage	 
	2020	 	 	106.75	%
	2021	 	 	104.50	%
	2022	 	 	102.25	%
	2023 and thereafter	 	 	100.00	%

Issuer may redeem all (but not a portion of) the Notes when
permitted by, and pursuant to the conditions in, Section 4.15(f) hereof.

 

(f)          Any
redemption pursuant to this Section 3.07 shall
be made pursuant to the provisions of Sections 3.01
through 3.06 hereof.

 

Section
3.08         Mandatory Redemption.

 

The Issuer is not required to make mandatory
redemption or sinking fund payments with respect to the Notes.

 

Section
3.09         Offer to Purchase by Application of Excess Proceeds.

 

In the event that, pursuant to Section
4.10 hereof, the Issuer is required to commence an Asset Sale Offer to all Holders to purchase Notes, it will follow the procedures
specified below.

 

The Asset Sale Offer shall be made to all
Holders and, if required by the terms of other Parity Lien Debt, to all holders of such other Parity Lien Debt. The Asset Sale
Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days,
except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than
three Business Days after the termination of the Offer Period (the “Purchase Date”), the Issuer will apply all
Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other Parity Lien Debt (on a pro rata
basis based on the principal amount of Notes and such other Parity Lien Debt surrendered, if applicable) or, if less than the Offer
Amount has been tendered, all Notes and other Parity Lien Debt tendered in response to the Asset Sale Offer. Payment for any Notes
so purchased will be made in the same manner as interest payments are made.

 

    	 	 61	 

     

    

 

If the Purchase Date is on or after an interest
record date and on or before the related interest payment date, any accrued and unpaid interest, if any, will be paid to the Person
in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to
Holders who tender Notes pursuant to the Asset Sale Offer.

 

Upon the commencement of an Asset Sale Offer,
the Issuer will send, by first class mail, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice
will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer.
The notice, which will govern the terms of the Asset Sale Offer, will state:

 

(a)          that
the Asset Sale Offer is being made pursuant to this Section 3.09
and Section 4.10 hereof and the length
of time the Asset Sale Offer will remain open;

 

(b)          the
Offer Amount, the purchase price and the Purchase Date;

 

(c)          that
any Note not tendered or accepted for payment will
continue to accrue interest;

 

(d)          that,
unless the Issuer defaults in making such payment, any Note
accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest
on and after the Purchase Date;

 

(e)          that
Holders electing to have a Note purchased pursuant
to an Asset Sale Offer may elect to have Notes purchased
in denominations of $1,000 or an integral multiple of $1.00
in excess thereof;

 

(f)          that
Holders electing to have Notes purchased pursuant
to any Asset Sale Offer will be required to surrender the Note,
with the form entitled “Option of Holder to Elect Purchase” attached to the
Notes completed, or transfer by book-entry transfer,
to the Issuer, a depositary, if appointed by the Issuer, or
a Paying Agent at the address specified in the notice at least three days before
the Purchase Date;

 

(g)          that
Holders will be entitled to withdraw their election if the Issuer, the Depositary
or the Paying Agent, as the case may be, receives, not later than the expiration
of the Offer Period, a telegram, electronic image scan, facsimile transmission or
letter setting forth the name of the Holder, the principal amount of the Note
the Holder delivered for purchase and a statement that such Holder
is withdrawing his election to have such Note purchased;

 

(h)          that,
if the aggregate principal amount of Notes surrendered
by Holders thereof exceeds the Offer Amount allocated
to the purchase of Notes in the Asset Sale Offer,
the Trustee will select the Notes to be purchased
on a pro rata basis (except that any Notes represented by a Global Note shall be selected
by such method as DTC or its nominee or successor
may require or, where such nominee or successor is
the Trustee, a method that most nearly approximates pro rata selection as the Trustee
deems fair and appropriate) based on the principal amount of Notes surrendered (with
such adjustments as may be deemed appropriate by the Issuer so that only Notes
in denominations of $1,000, or an integral multiple of
$1.00 in excess thereof, will be purchased); and

 

    	 	 62	 

     

    

 

(i)          that
Holders whose Notes were purchased only in part will
be issued new Notes equal in principal amount to the unpurchased portion of the Notes
surrendered (or transferred by book-entry transfer).

 

On or before the Purchase Date, the Issuer
will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Notes or portions thereof tendered
pursuant to the Asset Sale Offer and required to be purchased pursuant to this Section 3.09 and Section 4.10 hereof,
or if Notes in an aggregate principal amount less than the Offer Amount allocated to the purchase of Notes in the Asset Sale Offer
have been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together
with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Issuer in accordance
with the terms of this Section 3.09. The Issuer, the depositary for the Asset Sale Offer or the Paying Agent, as the case
may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder
an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Issuer for purchase, and the Issuer
will promptly issue a new Note, and the Trustee, upon written request from the Issuer, will authenticate and mail or deliver (or
cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of
the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer
will publicly announce the results of the Asset Sale Offer on the Purchase Date.

 

Article

COVENANTS

 

Section
4.01         Payment of Notes.

 

The Issuer will pay or cause to be paid
the principal of, premium on, if any, and interest on, the Notes on the dates and in the manner provided in the Notes. Principal,
premium, if any, and interest, will be considered paid on the date due if the Paying Agent, if other than the Issuer or a Subsidiary
of the Issuer, holds as of 10 a.m., New York City time, on the due date money deposited by the Issuer in immediately available
funds and designated for and sufficient to pay all principal, premium, if any, and interest, if any, then due.

 

The Issuer will pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at a rate that is 1% higher than the then
applicable interest rate on the Notes to the extent lawful; they will pay interest (including post-petition interest in any proceeding
under any Bankruptcy Law) on overdue installments of interest, if any (without regard to any applicable grace period), at the same
rate to the extent lawful.

 

    	 	 63	 

     

    

 

Section
4.02         Maintenance of Office or Agency.

 

The Issuer will maintain an office or agency
(which may be an office of the Trustee or an affiliate of the Trustee) where Notes may be surrendered for registration of transfer
or for exchange and where notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be served. The
Issuer will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency.
If at any time the Issuer fails to maintain any such required office or agency or fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

 

The Issuer may also from time to time designate
one or more other 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 will 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.

 

Section
4.03         Reports.

 

(a)          Whether
or not required by the rules and regulations of the Commission,
so long as any Notes are outstanding, the Issuer
will furnish to the Holders of the Notes or cause
the Trustee to furnish to the Holders of the Notes
(or file with the SEC for public availability),
within the time periods specified in the SEC’s rules and regulations applicable to
an accelerated filer:

 

(1)         all
quarterly and annual reports that would be required to be filed with the Commission on Forms
10-Q and 10-K if the Issuer were required to file such reports, and in any event including
a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” with respect to the
annual report only, a report on the Issuer’s consolidated financial statements by the Issuer’s certified independent

and

 

(2)         all
current reports that would be required to be filed with the Commission on Form 8-K if the
Issuer were required to file such reports.

 

The availability of the foregoing reports
on the SEC’s EDGAR filing system will be deemed to satisfy the foregoing delivery requirements. All such reports will be
prepared in all material respects in accordance with all of the rules and regulations applicable to such reports. If, notwithstanding
the foregoing, the SEC will not accept the Issuer’s filings for any reason, the Issuer will post the reports referred to
in the preceding paragraphs on its website within the time periods applicable to an accelerated filer that would apply if the Issuer
were required to file those reports with the SEC.

 

    	 	 64	 

     

    

 

(b)          For
so long as any Notes remain outstanding and are “restricted
securities” under Rule 144 under the Securities Act,
if at any time the Issuer is not required to file with the SEC
the reports required by Section 4.03(a), it will
furnish to Beneficial Owners of Notes and to prospective investors, upon request,
the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities
Act. The Issuer will also prepare or cause

Report as of December 31, will be prepared or audited
by independent reserve engineers.

 

(c)          If
the Issuer has designated any of its Subsidiaries as
Unrestricted Subsidiaries, then the quarterly and annual financial information required
by Section 4.03(a) will include, to the extent
material, a reasonably detailed presentation, either on the face of the financial statements or
in the footnotes thereto, and in “Management’s Discussion and Analysis of Financial Condition and Results of
Operations”, of the financial condition and results of operations of the Issuer and
its Restricted Subsidiaries separate from the financial condition and results of operations
of the Unrestricted Subsidiaries of the Issuer.

 

(d)          Any
and all Defaults or Events of Default arising from
a failure to furnish or file in a timely manner a report or
certification required by this Section 4.03
shall be deemed cured (and the Issuer shall be deemed to be in compliance with this
Section 4.03) upon furnishing or
filing such report or certification as contemplated by this Section 4.03
(but without regard to the date on which such report or certification is so furnished
or filed); provided that such cure shall not
otherwise affect the rights of the Holders under Article VI
hereof if the principal, premium, if any, and interest have been accelerated in accordance with the terms of this Indenture
and such acceleration has not been rescinded or cancelled prior to such cure.

 

Section
4.04         Compliance Certificate.

after the end of each fiscal year, beginning with the first fiscal year ending after the Issue Date, an Officers’
Certificate stating that a review of the activities of the Issuer and its Subsidiaries
during the preceding fiscal year has been made under the supervision of the signing Officers
with a view to determining whether the Issuer has kept, observed, performed and fulfilled
its obligations under this Indenture, and further
stating, as to each such Officer signing such certificate, that to the best of his or
her knowledge the Issuer has kept, observed, performed and fulfilled each and every
covenant contained in this Indenture and are not in default
in the performance or observance of any of the terms, provisions and conditions of
this Indenture (or, if a Default
or Event of Default has occurred, describing all such Defaults
or Events of Default of which he or she may
have knowledge and what action the Issuer is taking or propose
to take with respect thereto).

 

(b)          So
long as any of the Notes are outstanding, the Issuer
will deliver to the Trustee, forthwith upon any Officer
of the Issuer becoming aware of any Default or Event of Default,
a written statement specifying such Default or Event of Default
and what action the Issuer is taking or propose
to take with respect thereto.

4.05         Taxes.

 

The Issuer will pay, and will cause each
of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested
in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect
to the Holders of the Notes.

 

    	 	 65	 

     

    

 

Section
4.06         Stay, Extension and Usury Laws.

Subsidiaries’ Equity Interests (including, without limitation, any payment
in connection with any merger or consolidation involving the Issuer
or any of its Restricted Subsidiaries) or to
the direct or indirect holders of the Issuer’s or
any of its Restricted Subsidiaries’ Equity

the Fixed Charge Coverage Ratio for the Issuer’s most recently ended four full fiscal
quarters for which internal financial statements are available at the time of such Restricted
Payment (the “Trailing Four Quarters”) is not less than 2.25 to 1.0,
such Restricted Payment, together with the aggregate amount of all other Restricted
Payments made by the Issuer and its Restricted Subsidiaries
(excluding Restricted Payments permitted by clauses (2)

as one accounting period) from the first day of the fiscal quarter during which the Issue Date occurs to the end of the most recent
fiscal quarter ending prior to the date of such Restricted Payment for which internal financial statements are available (or, in
case such Consolidated Net Income is a deficit, minus 100% of such deficit); plus

 

(b)          100%

net reduction in Restricted Investments resulting from dividends, repayments of loans or
advances, or other transfers of assets in each case to the Issuer
or any of its Restricted Subsidiaries from any Person
(including, without limitation, Unrestricted Subsidiaries) or
from redesignations of Unrestricted Subsidiaries as Restricted
Subsidiaries (items (b), (c) and (d)
being referred to as “Incremental Funds”); minus

 

(1)         the
aggregate amount of Incremental Funds previously expended pursuant to this clause (I)
and clause (II) below; or

 

(II)        if
the Fixed Charge Coverage Ratio for the Trailing Four Quarters
is less than 2.25 to 1.0, such Restricted Payment, together with the aggregate amount
of all other Restricted Payments made by the Issuer and
its Restricted Subsidiaries (excluding Restricted Payments
permitted by clauses (2) through (13) of Section 4.07(b))

equity option agreement, unitholders’ agreement or similar agreement; provided
that the aggregate price paid for all such repurchased, redeemed, acquired or retired

included, (a) the cash proceeds received by the Issuer or any of its Restricted
Subsidiaries from sales of Equity Interests of the Issuer
to employees or directors of the Issuer or its

The amount of all Restricted Payments (other
than cash) will be the Fair Market Value, on the date of the Restricted Payment, of the Restricted Investment proposed to be made
or the asset(s) or securities proposed to be transferred or issued by the Issuer or any of its Restricted Subsidiaries, as the
case may be, pursuant to the Restricted Payment, except that the Fair Market Value of any non-cash dividend paid within 60 days
after the date of declaration will be determined as of such date of declaration. The Fair Market Value of any Restricted Investment,
assets or securities that are required to be valued by this Section 4.07 will be determined in accordance with the definition
of that term. For purposes of determining compliance with this Section 4.07, (x) in the event that a Restricted Payment
meets the criteria of more than one of the categories of Restricted Payments described in the preceding clauses (1) through (13)
of this Section 4.07(b), or is permitted pursuant to Section 4.07(a), the Issuer will be permitted to classify (or
later classify or reclassify in whole or in part in its sole discretion) such Restricted Payment (or portion thereof) on the date
made or later reclassify such Restricted Payment (or portion thereof) in any manner that complies with this Section 4.07;
and (y) in the event a Restricted Payment is made pursuant to clause (I) or (II) of Section 4.07(a), the Issuer will be

dividends or make any other distributions on its Capital
Stock to the Issuer or any of its Restricted Subsidiaries,

or any of its Restricted Subsidiaries; provided
that the priority that any series of Preferred Stock of a Restricted
Subsidiary has in receiving dividends or liquidating distributions before dividends
or liquidating distributions are paid in respect of common stock of such Restricted
Subsidiary shall not constitute a restriction on the ability to make dividends or distributions
on Capital Stock for purposes of this Section 4.08;

 

(2)         make
loans or advances to the Issuer or any of its Restricted
Subsidiaries (it being understood that the subordination of loans or advances made
to the Issuer or any Restricted Subsidiary to other
Indebtedness incurred by the Issuer or any Restricted
Subsidiary shall not be deemed a restriction on the ability to make loans or advances);
or

 

(3)         sell,
lease or transfer any of its properties or assets
to the Issuer or any of its Restricted Subsidiaries.

taken as a whole, than those contained in this Indenture, the Notes
and the Note Guarantees or the Credit Agreement as
in effect on the Issue Date;

 

(4)         applicable
law, rule, regulation, order, approval, license, permit or similar restriction;

Capital Stock was incurred in connection with or in contemplation of such acquisition),
which encumbrance or restriction is not applicable to any Person,
or the properties or assets of any Person,
other than the Person, or the property
or assets of the Person, so acquired; provided

(8)         any
agreement for the sale or other disposition of a Restricted
Subsidiary that restricts distributions by that Restricted Subsidiary pending its
sale or other disposition;

 

(9)         Permitted
Refinancing Indebtedness; provided that the restrictions contained in the
agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive,
taken as a whole, than those contained in the agreements governing the Indebtedness being
refinanced;

 

(10)        Liens
permitted to be incurred under the provisions of Section 4.12
that limit the right of the debtor to dispose of the assets subject to such Liens;

Restricted Subsidiary of the Issuer to pay dividends
or make any other distributions on its Equity Interests
(other than requirements to pay dividends or liquidation preferences on such Preferred
Stock prior to paying any dividends or making any other distributions on such other
Equity Interests);

 

(15)        in
the case of any Foreign Subsidiary, any encumbrance or restriction
contained in the terms of any Indebtedness or any agreement pursuant to which such Indebtedness
was incurred if either (a) the encumbrance or restriction applies only in the event
of a payment default or a default with respect to
a financial covenant in such Indebtedness or agreement or
(b) the Issuer determines that any such encumbrance of restriction will
not materially affect the Issuer’s ability to make principal or interest payments
on the Notes, as determined in good faith by the Board of
Directors of the Issuer, whose determination shall be conclusive;

 

(16)        restrictions
created in connection with any Receivables Facility that in the good faith determination

Stock; provided, however, that the Issuer
may incur Indebtedness (including Acquired Debt)
or issue Disqualified Stock, and the Guarantors
may incur Indebtedness (including Acquired Debt)
or issue Preferred Stock, if the Fixed
Charge Coverage Ratio for the Issuer’s most recently ended four full fiscal quarters
for which internal financial statements are available immediately preceding the date on which such additional Indebtedness
is incurred or such Disqualified Stock or such
Preferred Stock is issued, as the case may be, would have been at least 2.25 to 1.0, determined
on a pro forma basis (including a pro forma application of the net proceeds therefrom),
as if the additional Indebtedness had been incurred or the
Disqualified Stock or the Preferred Stock had been
issued, as the case may be, at the beginning of such four-quarter period.

accreted value, as applicable) at any time outstanding, including all Permitted
Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge
any Indebtedness incurred or Disqualified Stock issued
pursuant to this clause (16), not to exceed the greater of (i) $50.0
million and (ii) 5.0% of the Issuer’s Modified ACNTA determined on the date
of such incurrence or issuance; and

 

(17)        (a)
Indebtedness incurred by a Receivables Subsidiary in
a Receivables Facility that is without recourse to the Issuer
or any Restricted Subsidiary other than the Receivables
Subsidiary (except for Securitization Undertakings) and (b) to the extent constituting
Indebtedness, obligations of the Issuer
or a Restricted Subsidiary as seller or servicer
under a Receivables Facility and any guarantee by
the Issuer of such Indebtedness.

 

The Issuer will not incur, and will not
permit any Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment
to any other Indebtedness of the Issuer or such Guarantor unless such Indebtedness is also contractually subordinated in right
of payment to the Notes or the applicable Note Guarantee on substantially identical terms; provided, however, that
no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Issuer or
any Guarantor solely by virtue of being unsecured or by virtue of being secured on a junior priority basis.

 

    	 	 75	 

     

    

 

For purposes of determining compliance with
this Section 4.09, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted
Debt described in clauses (1) through (17) above, or is entitled to be incurred pursuant to Section 4.09(a), the Issuer
will be permitted to divide, classify and reclassify such item of Indebtedness on the date of its incurrence, or later redivide
or reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. Indebtedness
under Credit Facilities outstanding on the date on which Notes are first issued and authenticated under this Indenture will initially
be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted
Debt and in all such cases may not be reclassified.

 

The accrual of interest or Preferred Stock
dividends, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness not secured by
a Lien in the form of additional Indebtedness with the same terms, the reclassification of Preferred Stock as Indebtedness due
to a change in accounting principles, and the payment of dividends on Preferred Stock or Disqualified Stock in the form of additional
securities of the same class of Preferred Stock or Disqualified Stock will not be deemed to be an incurrence of Indebtedness or
an issuance of Preferred Stock or Disqualified Stock for purposes of this Section 4.09; provided that the amount
thereof is included in Fixed Charges of the Issuer as accrued to the extent required by the definition of such term.

 

The amount of any Indebtedness outstanding
as of any date will be:

 

(1)         the
accreted value of the Indebtedness, in the case of any Indebtedness
issued with original issue discount;

 

(2)         the
principal amount of the Indebtedness, in the case of any other Indebtedness;
and

 

(3)         in
respect of Indebtedness of another Person secured
by a Lien on the assets of the specified Person,
the lesser of:

 

(a)          the
Fair Market Value of such assets at the date of determination; and

 

(b)          the
amount of the Indebtedness of the other Person.

 

Section
4.10         Asset Sales.

 

(a)          The
Issuer will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless:

 

(1)         the
Issuer (or a Restricted
Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at
least equal to the Fair Market Value (measured as of the date of the definitive agreement
with respect to such Asset Sale) of the assets or Equity
Interests issued or sold or otherwise disposed
of; and

 

    	 	 76	 

     

    

 

(2)         at
least 75% of the aggregate consideration received in the Asset Sale by the Issuer
or a Restricted Subsidiary and all other Asset Sales
since the Issue Date is in the form of cash or Cash Equivalents. For purposes of
this provision, each of the following will be deemed to be cash:

 

(i)          any
liabilities, as shown on the Issuer’s most recent consolidated balance sheet, of the Issuer
or any Restricted Subsidiary (other than contingent liabilities and liabilities that
are by their terms subordinated to the Notes or any Note
Guarantee) that are assumed by the transferee of any such assets pursuant to a customary novation or
indemnity agreement that releases the Issuer or such Restricted
Subsidiary from or indemnifies against further liability;

 

(ii)         with
respect to any Asset Sale of oil and gas properties by
the Issuer or any of its Restricted Subsidiaries,
the costs and expenses related to the exploration, development, completion or production
of such properties and activities related thereto which the transferee (or an Affiliate
thereof) agrees to pay; and

 

(iii)        any
securities, notes or other obligations received by
the Issuer or any Restricted Subsidiary from such
transferee that are, within 90 days of the Asset Sale, converted by the Issuer
or such Restricted Subsidiary into cash, to the extent of the cash received in that
conversion.

 

(b)          Within
360 days after the receipt of any Net Proceeds from an Asset
Sale, the Issuer (or any Restricted
Subsidiary) may apply such Net Proceeds at its option to any combination of the following:

 

(1)         to
redeem the Notes as provided under Section 3.07
or to permanently repay, redeem, repurchase or reduce any Priority
Lien Debt and other outstanding Priority Lien Obligations or any Parity
Lien Debt other than the Notes; provided that,
if the Issuer or any Restricted Subsidiary shall
so repay, redeem or reduce any Parity Lien Debt in
addition to the Notes, the Issuer or such Restricted
Subsidiary will redeem or equally and ratably repurchase (or
offer to repurchase) the Notes as provided either,
at the Issuer’s option, pursuant to Section 3.07,
through open-market purchases (to the extent such purchases are at a purchase price at or
above 100% of the principal amount of such Notes purchased, plus
accrued but unpaid interest, if any) or by making an offer (in accordance with the
procedures set forth below for an Asset Sale Offer (as defined below)) to all Holders
to purchase their Notes at 100% of the principal
amount thereof, plus the amount of accrued but unpaid interest, if any, on the amount of Notes
that would otherwise be prepaid to the date of such repurchases;

 

(2)         invest
in or acquire Additional Assets; or

 

(3)         to
make capital expenditures in respect of the Issuer’s or any Restricted
Subsidiaries’ Oil and Gas Business.

 

(c)          The
requirements of clause (2) or (3) of Section 4.10(b)
shall be deemed to be satisfied if a bona fide binding contract committing to make the investment, acquisition or
expenditure referred to therein is entered into by the Issuer (or
any Restricted Subsidiary) with a Person other
than an Affiliate of the Issuer within the time period
specified in such preceding paragraph and such Net Proceeds are subsequently applied in
accordance with such contract within six months following the date such agreement is entered into.

 

    	 	 77	 

     

    

 

(d)          Pending
the final application of any Net Proceeds, the Issuer (or
any Restricted Subsidiary) may invest the Net Proceeds
in any manner that is not prohibited by this Indenture.

 

(e)          Any
Net Proceeds from Asset Sales that are not applied
or invested as provided in Section 4.10(b)
will constitute “Excess Proceeds.” When the aggregate amount
of Excess Proceeds exceeds $20.0 million, within five days thereof, the Issuer
will make an offer to all Holders and, if required by the terms of other Parity
Lien Debt, to all holders of such other Parity Lien Debt to purchase, prepay or
redeem, on a pro rata basis, the maximum principal amount of Notes and such other
Parity Lien Debt (plus all accrued interest and the amount of all fees and expenses, including
premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out
of the Excess Proceeds (an “Asset Sale Offer”). The offer price in any
Asset Sale Offer will be equal to 100% of the principal
amount, plus accrued and unpaid interest, if any, to the date of purchase, prepayment
or redemption, subject to the rights of Holders on the relevant
record date to receive interest due on the relevant interest payment date, and will be
payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer,
the Issuer or any Restricted Subsidiary may use those
Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If
the aggregate principal amount of Notes and other Parity
Lien Debt, if applicable, tendered in such Asset Sale Offer exceeds the amount of
Excess Proceeds, the Trustee will select the Notes and
such other Parity Lien Debt to be purchased on a pro rata basis (except that any Notes
represented by a Note in global form will be
selected by such method as DTC or its nominee or successor
may require or, where such nominee or successor is
the Trustee, a method that most nearly approximates pro rata selection as the Trustee
deems fair and appropriate), based on the principal amounts tendered (with such adjustments as may be deemed appropriate
by the Issuer so that only Notes in denominations
of $1,000, or an integral multiple of $1.00 in excess thereof,
will be purchased). Upon completion of each Asset Sale Offer,
the amount of Excess Proceeds will be reset at zero.

 

(f)          The
Issuer will comply with the requirements of Rule 14e-1 under the Exchange
Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in
connection with each repurchase of Notes and other Parity
Lien Debt, if applicable, pursuant to an Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with Section 3.09
or this Section 4.10, the Issuer will comply
with the applicable securities laws and regulations and will not be deemed to have breached
its obligations under Section 3.09
or this Section 4.10 by virtue of such
compliance.

 

Section
4.11         Transactions with Affiliates.

 

(a)          The
Issuer will not, and will not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or
purchase any property or assets from, or enter
into or make or amend any transaction, contract,
agreement, understanding, loan, advance or Guarantee with, or
for the benefit of, any Affiliate of the Issuer (each,
an “Affiliate Transaction”), unless:

 

    	 	 78	 

     

    

 

(1)         the
Affiliate Transaction is on terms that are no less favorable to the Issuer
or the relevant Restricted Subsidiary than those that could have been obtained in
a comparable transaction by the Issuer or such Restricted
Subsidiary with an unrelated Person or, if in the good faith judgment of the Issuer’s
Board of Directors, no comparable transaction is available with which to compare such Affiliate
Transaction, such Affiliate Transaction is otherwise fair to the Issuer
or the relevant Restricted Subsidiary from a financial point of view; and

 

(2)         the
Issuer delivers to the Trustee:

 

(a)          with
respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $20.0 million, an Officers’
Certificate certifying that such Affiliate Transaction or series of related Affiliate
Transactions complies with this Section 4.11; and

 

(b)          with
respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $40.0 million, a resolution
of the Board of Directors of the Issuer set forth
in an Officers’ Certificate certifying that such Affiliate
Transaction or series of related Affiliated Transactions complies with this Section
4.11 and that such Affiliate
Transaction or series of related Affiliate Transactions has been approved by either
the Conflicts Committee of the Board of Directors of the Issuer
(so long as the members of the Conflicts Committee approving the Affiliate Transaction or
series of related Affiliate Transactions are disinterested) or
a majority of the disinterested members of the Board of Directors of the Issuer,
if any.

 

(b)          The
following items will not be deemed to be Affiliate Transactions
and, therefore, will not be subject to the provisions of Section 4.11(a)
hereof:

 

(1)         any
employment agreement, employee benefit plan, officer or director indemnification agreement
or any similar arrangement entered into by the Issuer or
any of its Restricted Subsidiaries in the ordinary course of business and payments
pursuant thereto;

 

(2)         transactions
between or among the Issuer and/or
its Restricted Subsidiaries;

 

(3)         transactions
with a Person (other than an Unrestricted Subsidiary of
the Issuer) that is an Affiliate of the Issuer solely
because the Issuer owns, directly or through a Restricted
Subsidiary, an Equity Interest in, or controls,
such Person;

 

(4)         payment
of reasonable and customary fees and reimbursements of expenses (pursuant to indemnity arrangements or
otherwise) of officers, directors, employees or consultants of the Issuer
or any of its Restricted Subsidiaries;

 

(5)         any
issuance of Equity Interests (other than Disqualified Stock)
of the Issuer to Affiliates of the Issuer;

 

    	 	 79	 

     

    

 

(6)         any
Permitted Investments or Restricted Payments that are permitted by Section 4.07;

 

(7)         transactions
between the Issuer or any of its Restricted Subsidiaries
and any Person that would not otherwise constitute an Affiliate
Transaction except for the fact that one director of such other Person is also a
director of the Issuer or such Restricted Subsidiary,
as applicable; provided that such director abstains from voting as a director of
the Issuer or such Restricted Subsidiary, as applicable,
on any matter involving such other Person;

 

(8)         any
transaction in which the Issuer or any of its Restricted
Subsidiaries, as the case may be, delivers to the Trustee a letter from an accounting,
appraisal, advisory or investment banking firm of national standing stating that such transaction
is fair to the Issuer or such Restricted Subsidiary from
a financial point of view or that such transaction meets the requirements of Section
4.11(a)(1);

 

(9)         (A)
guarantees by the Issuer or any of its Restricted Subsidiaries
of performance of obligations of the Issuer’s Unrestricted
Subsidiaries in the ordinary course of business, except for guarantees of Indebtedness in
respect of borrowed money, and (B) pledges by the Issuer or any Restricted
Subsidiary of the Issuer of Equity Interests in
Unrestricted Subsidiaries for the benefit of lenders or
other creditors of the Issuer’s Unrestricted Subsidiaries;

 

(10)        any
Affiliate Transaction with a Person in its capacity
as a holder of Indebtedness or Capital Stock of the
Issuer or any Restricted Subsidiary of the Issuer
if such Person is treated no more favorably than the other holders of Indebtedness
or Capital Stock of the Issuer or such Restricted
Subsidiary;

 

(11)        transactions
with Unrestricted Subsidiaries, customers, clients, suppliers or
purchasers or sellers of goods or services,
or lessors or lessees of property,
in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture
which are, in the aggregate (taking into account all the costs and benefits associated with such transactions), not materially
less favorable to the Issuer and its Restricted Subsidiaries
than those that would have been obtained in a comparable transaction by the Issuer or such
Restricted Subsidiary with an unrelated person, in
the good faith determination of the Issuer’s Board of Directors or any officer
of the Issuer involved in or otherwise familiar
with such transaction, or are on terms at least as favorable as might reasonably have been
obtained at such time from an unaffiliated party;

 

(12)        in
the case of contracts for exploring for, producing, marketing, storing or otherwise handling
Hydrocarbons, or activities or
services reasonably related or ancillary thereto, or
other operational contracts, any such contracts entered into in the ordinary course of business and otherwise in compliance
with the terms of this Indenture (a) which are fair to the Issuer
and its Restricted Subsidiaries, in the reasonable determination of the Board
of Directors of the Issuer or the senior management thereof, or
are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party;

 

    	 	 80	 

     

    

 

(13)        sales
of accounts receivable, or participations therein, or related
assets effected in connection with any Receivable Facility or any related transaction effected
in order to consummate a financing contemplated by a Receivables Facility; and

 

(14)        payments
under the Plan of Reorganization as in effect on the Issue Date.

 

Section
4.12         Liens.

 

The Issuer will not, and will not permit
any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien
of any kind (other than Permitted Liens) securing Indebtedness upon any of their property or assets, now owned or hereafter acquired.

 

Section
4.13         [Reserved].

 

Section
4.14         Organizational Existence.

 

Subject to Article V and Section
10.04 hereof, the Issuer shall do or cause to be done all things necessary to preserve and keep in full force and effect:

 

(a)          its
corporate existence, and the corporate, partnership or other
existence of each of its Restricted Subsidiaries, in accordance with the respective organizational
documents (as the same may be amended from time to time) of the Issuer or any such Restricted
Subsidiary; and

 

(b)          the
rights (charter and statutory), licenses and franchises of the Issuer and its Restricted
Subsidiaries; provided, however, that the Issuer
shall not be required to preserve any such right, license or franchise, or
the corporate, partnership or other existence of any of its Restricted
Subsidiaries, if the Issuer shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Issuer and its Restricted
Subsidiaries, taken as a whole.

 

Section
4.15         Offer to Repurchase Upon Change
of Control.

 

(a)          If
a Change of Control occurs, each Holder will have
the right to require the Issuer to repurchase all or any
part (equal to $1,000 or an integral multiple of $1.00 in
excess thereof) of that Holder’s Notes pursuant to a cash tender offer (“Change
of Control Offer”) on the terms set forth in this Section 4.15.
In the Change of Control Offer, the Issuer will offer
a payment in cash (“Change of Control Payment”) equal to 101% of
the aggregate principal amount of Notes repurchased, plus
accrued and unpaid interest, if any, on the Notes repurchased to the date of purchase
(the “Change of Control Purchase Date”), subject to the rights of Holders
of Notes on the relevant record date to receive interest due on the relevant interest payment date.

 

    	 	 81	 

     

    

 

Within 30 days following any Change of Control,
the Issuer will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and
offering to repurchase Notes properly tendered prior to the expiration date specified in the notice, which date will be no earlier
than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures required by this Section
4.15 and described in such notice. The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any
other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations
conflict with this Section 4.15, the Issuer will comply with the applicable securities laws and regulations and will not
be deemed to have breached its obligations under this Section 4.15 by virtue of such compliance.

 

(b)          Promptly
following the expiration of the Change of Control Offer, the Issuer
will, to the extent lawful, accept for payment all Notes or portions of Notes
properly tendered pursuant to the Change of Control Offer. Promptly after such acceptance,
the Issuer will, on the Change of Control Purchase Date:

 

(1)         deposit
with the Paying Agent an amount equal to the Change of Control
Payment in respect of all Notes or portions of Notes
accepted for payment; and

 

(2)         deliver
or cause to be delivered to the trustee the Notes
properly accepted together with an Officers’ Certificate stating the aggregate principal
amount of Notes or portions of Notes being
purchased by the Issuer.

 

The Paying Agent will promptly mail (but
in any case not later than five days after the Change of Control Payment Date) to each Holder of Notes properly tendered the Change
of Control Payment for such Notes (or, if all the Notes are then in global form, it will make such payment through the facilities
of DTC), and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note
equal in principal amount to any unpurchased portion of the Notes surrendered, if any. The Issuer will publicly announce the results
of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

 

(c)          The
provisions described above that require the Issuer to make a Change
of Control Offer following a Change of Control will be applicable whether or
not any other provisions of this Indenture are applicable.

 

(d)          Notwithstanding
anything to the contrary in this Section 4.15, the Issuer
will not be required to make a Change of Control Offer upon a Change
of Control if (1) a third party makes the Change of Control Offer in the manner,
at the time and otherwise in compliance with the requirements set forth in this Section 4.15
applicable to a Change of Control Offer made by the Issuer
and purchases all Notes properly tendered and not withdrawn under the Change
of Control Offer, (2) notice of redemption of all outstanding Notes has been given
pursuant to Section 3.03, unless and until there is a default
in payment of the applicable redemption price or (3) in connection with or
in contemplation of any Change of Control, the Issuer
has made an offer to purchase (an “Alternate Offer”) any and all
Notes validly tendered at a cash price equal to or higher
than the Change of Control Payment and has purchased all Notes
properly tendered in accordance with the terms of such Alternate Offer.

 

    	 	 82	 

     

    

 

(e)          Notwithstanding
anything to the contrary contained in this Indenture, a Change
of Control Offer may be made in advance of a Change of Control, conditioned upon
the consummation of such Change of Control, if a definitive agreement is in place for the
Change of Control at the time the Change of Control Offer
is made.

 

(f)          In
the event that the Holders of not less than 90% in aggregate
principal amount of the outstanding Notes accept a Change of Control Offer and the
Issuer (or any third party making such Change
of Control Offer in lieu of the Issuer as described above) purchases all of the Notes
held by such Holders, the Issuer will have
the right, upon not less than 30 nor more than 60 days prior notice, given not more than 30 days following the purchase pursuant
to the Change of Control Offer described above, to redeem all of the Notes
that remain outstanding following such purchase at a redemption price equal to the
Change of Control Payment plus, to the extent not included in the Change
of Control Payment, accrued and unpaid interest, if any, on the Notes that remain
outstanding, to the date of redemption (subject to the rights of Holders of
record on the relevant record date to receive interest due on an interest payment date that is on or
prior to the redemption date).

 

Section
4.16         Additional Note Guarantees.

 

If, after the Issue Date, any Restricted
Subsidiary of the Issuer that is not already a Guarantor Guarantees any Indebtedness of the Issuer or any Guarantor incurred under
any Credit Facility, or any Domestic Subsidiary (other than a Receivables Subsidiary), if not then a Guarantor, incurs any Indebtedness
under any Credit Facility, then in either case that Subsidiary will become a Guarantor by executing a supplemental indenture substantially
in the form of Exhibit F hereto and delivering it to the Trustee within 20 business days of the date on which it Guaranteed
or incurred such Indebtedness, as the case may be. Notwithstanding the preceding, any Note Guarantee of a Restricted Subsidiary
that was incurred pursuant to this paragraph shall provide by its terms that it shall be automatically and unconditionally released
at such time as such Guarantor ceases both (a) to Guarantee any other Indebtedness of the Issuer and any Indebtedness of any other
Guarantor (except as a result of payment under any such other Guarantee) and (b) to be an obligor with respect to any Indebtedness
under any Credit Facility.

 

Section
4.17         Designation of Restricted and Unrestricted
Subsidiaries.

 

The Board of Directors of the Issuer may
designate any Restricted Subsidiary of the Issuer to be an Unrestricted Subsidiary if that designation would not cause a Default.
If a Restricted Subsidiary of the Issuer is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding
Investments owned by the Issuer and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will
be deemed to be either an Investment made as of the time of the designation that will reduce the amount available for Restricted
Payments under Section 4.07(a) hereof or represent a Permitted Investment under one or more clauses of the definition of
Permitted Investments, as determined by the Issuer. That designation will only be permitted if the Investment would be permitted
at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

 

    	 	 83	 

     

    

 

Any designation of a Subsidiary of the Issuer
as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a Board Resolution giving effect to such
designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was
permitted by Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements
as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any
Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Issuer as of such date and, if
such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof, the Issuer will be in default
of such covenant.

 

The Board of Directors of the Issuer may
at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Issuer; provided that such designation
will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Issuer of any outstanding Indebtedness of
such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under Section
4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable reference
period; and (2) no Default or Event of Default would be in existence following such designation.

 

Section
4.18         Covenant Termination.

 

Notwithstanding any provision of this Indenture
or of the Notes to the contrary, if at any time following the Issue Date (a) the Notes are rated Baa3 or better by Moody’s
and BBB- or better by S&P (or, if either such entity ceases to rate the Notes for reasons outside of the control of the Issuer,
the equivalent investment grade credit rating from any other “nationally recognized statistical rating organization”
within the meaning of Section 3(a)(62) of the Exchange Act selected by the Issuer as a replacement agency), (b) no Default or Event
of Default shall have occurred and is continuing under this Indenture and (c) the Issuer has delivered to the Trustee an Officers’
Certificate certifying to such events, Sections 3.09, 4.07, 4.08, 4.09, 4.10, 4.11, 4.17
and 5.01(a)(4) of this Indenture will terminate and no Default or Event of Default shall result from any failure to comply
with any of the provisions of such Sections.

(whether or not such Issuer is the survivor),
or (2) sell, assign, transfer, convey, lease or otherwise
dispose of all or substantially all of its properties or
assets, in one or more related transactions, to another Person,

prior to such transaction or (B) immediately after giving
effect to such transaction on a pro forma basis, the Consolidated Net Worth of the
Issuer would be greater than the Consolidated Net Worth
of the Issuer immediately prior to such transaction;

 

(5)         the

the manner and to the extent required under the Note Documents and shall deliver an Opinion
of Counsel as to the enforceability of any amendments, supplements or other instruments
with respect to the Note Documents to be executed, delivered, filed and recorded, as applicable,

federal or state income taxation as an entity or (B)
is considered to be an “includible corporation” of an affiliated group of corporations within the meaning of Section
1504(b) of the Code or any similar state or local

all of the properties or assets of the Issuer.

 

Section
5.02         Successor Issuer Substituted.

 

Upon any consolidation or merger, or any
sale, assignment, transfer, conveyance, lease or other disposition of all or substantially all of the properties or assets of the
Issuer in a transaction that is subject to, and that complies with the provisions of, Section 5.01 hereof, the Surviving
Entity shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, assignment,
transfer, lease, conveyance or other disposition, the provisions of this Indenture referring to an “Issuer” shall refer
instead to the successor Person and not to the predecessor Issuer), and may exercise every right and power of the Issuer under
this Indenture with the same effect as if such successor Person had been named as the predecessor Issuer herein; provided,
however, that the predecessor Issuer shall not be relieved from the obligation to pay the principal of, or premium or interest,
if any, on, the Notes in the case of a lease of all or substantially all of the Issuer’s properties or assets in a transaction
that is subject to, and that complies with the provisions of, Section 5.01 hereof.

Section
6.01         Events of Default.

by the Issuer to comply with the provisions of Section 3.09,
4.10, 4.15 or 5.01 hereof;

 

(d)          failure
by the Issuer for 120 days after notice to the Issuer by
the Trustee or the Holders of at least 25% in
aggregate principal amount of the Notes then outstanding to comply with Section 4.03;

 

    	 	 86	 

     

    

 

(e)          failure
by the Issuer for 60 days after notice to the Issuer by
the Trustee or the Holders of at least 25% in
aggregate principal amount of the Notes then outstanding to comply with any of its other agreements in this Indenture;

 

(f)          default
under any mortgage, indenture or instrument under which there may be issued or
by which there may be secured or evidenced any Indebtedness
for money borrowed by the Issuer or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Issuer
or any of its Restricted Subsidiaries), whether such Indebtedness
or Guarantee now exists, or is created after the Issue Date, if that default:

 

(1)         is
caused by a failure to pay principal of, premium on, if any, or interest, if any, on such
Indebtedness prior to the expiration of the grace period provided
in such Indebtedness on the date of such default
(a “Payment Default”); or

 

(2)         results
in the acceleration of such Indebtedness prior to its express maturity,

 

and, in each case, the principal amount of
any such Indebtedness, together with the principal amount of any other such Indebtedness
under which there has been a Payment Default or the maturity of which has been so
accelerated, aggregates $15.0 million or more; provided,

any such Payment Default is cured or waived,
(ii) any such acceleration is rescinded, or (iii) such Indebtedness
is repaid during the 60 day period commencing upon the end of any applicable grace period for such Payment
Default or the occurrence of such acceleration, as the case may be, any Default or Event
of Default (but not any acceleration of the Notes)

as such rescission does not conflict with any judgment, decree or applicable law;

 

(g)          failure
by the Issuer or any of its Restricted Subsidiaries to
pay final judgments entered by a court or courts of competent jurisdiction aggregating in
excess of $15.0 million (to the extent not covered by insurance by a reputable and creditworthy

    	 	 87	 

     

    

 

(i)          a
court of competent jurisdiction enters an order or decree under any Bankruptcy
Law that:

 

(1)         is
for relief against the Issuer or any of the Issuer’s Restricted Subsidiaries that is a Significant
Subsidiary or any group of Restricted Subsidiaries of the Issuer that, taken together, would constitute a Significant Subsidiary
in an involuntary case;

 

(2)         appoints
a custodian of the Issuer or any of the Issuer’s Restricted
Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Issuer that, taken together, would
constitute a Significant Subsidiary or for all or substantially all of the property
of the Issuer or any of its Restricted Subsidiaries
that is a Significant Subsidiary or any group of
Restricted Subsidiaries of the Issuer that, taken together, would constitute a Significant
Subsidiary; or

 

(3)         orders
the liquidation of the Issuer or any of the Issuer’s Restricted Subsidiaries that is a Significant
Subsidiary or any group of Restricted Subsidiaries of the Issuer that, taken together, would constitute a Significant Subsidiary,

 

and the order or
decree remains unstayed and in effect for 60 consecutive days;

 

(j)          except
as permitted by this Indenture, any Note Guarantee is
held in any judicial proceeding to be unenforceable or invalid or
ceases for any reason to be in full force and effect, or any Guarantor,
or any Person acting on behalf of any Guarantor,
denies or disaffirms its obligations under its Note
Guarantee, except, in each case, by reason of the release of such Note Guarantee in
accordance with this Indenture; and

 

(k)          the
occurrence of the following:

 

(1)         except
as permitted by the Note Documents, any Note Document establishing
the Parity Liens ceases for any reason to be fully enforceable; provided
that it will not be an Event of Default
under this Section 6.01(k)(1) if the
sole result of the failure of one or more Note Documents
to be fully enforceable is that any Parity Lien purported to be granted under such
Note Document on Collateral, individually or
in the aggregate, having a Fair Market Value of not more than $15.0
million, ceases to be an enforceable and perfected Parity Lien; provided,
further, that if such failure is susceptible to cure, no Event of Default
shall arise with respect thereto until 45 days after any Officer of the Issuer
or any of its Restricted Subsidiaries becomes aware of such failure, which failure
has not been cured during such time period;

 

(2)         except
as permitted by the Note Documents, any Parity Lien purported
to be granted under any Note Document on Collateral,
individually or in the aggregate, having a Fair Market Value
in excess of $15.0 million, ceases to be an enforceable and perfected second priority
Lien, subject to the Intercreditor Agreement and Permitted
Collateral Liens; provided that if such failure is susceptible to cure, no
Event of Default shall arise with respect thereto
until 45 days after any Officer of the Issuer or any
Restricted Subsidiary becomes aware of such failure, which failure has not been cured during
such time period; and

 

    	 	 88	 

     

    

 

(3)         the
Issuer or any other Grantor, or
any Person acting on behalf of any of them, denies or
disaffirms, in writing, any obligation of the Issuer or any other Grantor
set forth in or arising under any Note Document establishing
Parity Liens (other than the obligations under any
Note Document of any Guarantor that has been released
of its obligations under such Note Document in accordance
with the terms thereof).

 

Section
6.02         Acceleration.

 

In the case of an Event of Default specified
in clause (h) or (i) of Section 6.01 hereof, with respect to the Issuer, any Restricted Subsidiary of the Issuer that is
a Significant Subsidiary or any group of Restricted Subsidiaries of the Issuer that, taken together, would constitute a Significant
Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event
of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding
Notes may declare all the Notes to be due and payable immediately.

 

Upon any such declaration, the Notes shall
become due and payable immediately.

 

The Holders of a majority in aggregate principal
amount of the then outstanding Notes by written notice to the Issuer and the Trustee may, on behalf of all of the Holders of all
the Notes, rescind an acceleration and its consequences hereunder, if the rescission would not conflict with any judgment or decree
and if all existing Events of Default (except nonpayment of principal of, or premium or interest, if any, on the Notes that has
become due solely because of the acceleration) have been cured or waived.

 

Section
6.03         Other Remedies.

 

If an Event of Default occurs and is continuing,
the Trustee may pursue any available remedy to collect the payment of principal of, or premium or interest, if any, on, the Notes
or to enforce the performance of any provision of the Notes or this Indenture.

 

The Trustee may maintain a proceeding even
if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or
any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

 

Section
6.04         Waiver of Past Defaults.

 

The Holders of a majority in aggregate principal
amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all of the Notes, waive
any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the
payment of principal of, or premium or interest, if any, on, the Notes (including in connection with an offer to purchase). Upon
any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured
for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent
thereon.

 

    	 	 89	 

     

    

 

Section
6.05         Control by Majority.

 

Holders of a majority in aggregate principal
amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy
available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction
that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders
or that may involve the Trustee in personal liability.

 

Section
6.06         Limitation on Suits.

 

No Holder of a Note may pursue any remedy
with respect to this Indenture or the Notes unless:

 

(a)          such
Holder has previously given to the Trustee written
notice that an Event of Default is continuing;

 

(b)          Holders
of at least 25% in aggregate principal amount of the then outstanding Notes make a
written request to the Trustee to institute proceedings in respect of an Event of Default
in its own name as Trustee under the Indenture;

 

(c)          such
Holder or Holders offer and, if requested, provide to the Trustee
security or indemnity reasonably satisfactory to the Trustee
against any cost, loss, liability or expense;

 

(d)          the
Trustee does not comply with such request for 60 days after receipt of the request and the
offer of security or indemnity; and

 

(e)          during
such 60-day period, Holders of a majority in aggregate principal amount of the then outstanding
Notes do not give the Trustee a direction inconsistent with such written request.

 

A Holder of a Note may not use this Indenture
to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note.

 

Section
6.07         Rights of Holders of Notes
to Receive Payment.

 

Notwithstanding any other provision of this
Indenture, the right of any Holder of a Note to receive payment of principal of, or premium or interest, if any, on, the Note,
on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit
for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent
of such Holder.

 

Section
6.08         Collection Suit by Trustee.

 

If an Event of Default specified in Sections
6.01(a) or (b) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as
trustee of an express trust against the Issuer for the whole amount of principal of, or premium or interest, if any, remaining
unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be
sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel.

Section
6.09         Trustee May File Proofs of Claim.

 

The Trustee is authorized to file such proofs
of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any
claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders
of the Notes allowed in any judicial proceedings relative to the Issuer (or any other obligor upon the Notes), its creditors or
its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable
on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments
to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay
to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee
under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same
shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties
that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement
or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any
Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

 

Section

of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, if any, respectively;
and

 

Third: to the Issuer or to such party
as a court of competent jurisdiction shall direct.

Section
6.11         Undertaking for Costs.

 

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 a Trustee, a court in
its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in

by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

 

Article
VII.

TRUSTEE

 

Section
7.01         Duties of Trustee.

 

(a)          If
an Event of Default has occurred and is continuing,
the Trustee will exercise such of the rights and powers vested in it by this Indenture,
and use the same degree of care and skill in its exercise, as a prudent man would exercise or use
under the circumstances in the conduct of his own affairs.

 

(b)          Except
during the continuance of an Event of Default:

 

(i)          the
duties of the Trustee will be determined solely by the express provisions of this Indenture
and the Trustee need perform only those duties that are specifically set forth in
this Indenture and no others, and no implied covenants or
obligations shall be read into this Indenture against the Trustee;
and

 

(ii)         in
the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth
of the statements and the correctness of the opinions expressed therein, upon certificates or opinions
furnished to the Trustee and conforming to the requirements of this Indenture.
However, in the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished
to the Trustee, the Trustee will examine the certificates and opinions to determine whether or not they conform to the requirements
of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

 

(c)          The
Trustee may not be relieved from liabilities for its own grossly negligent action, its own
grossly negligent failure to act, or its own willful misconduct, except that:

 

(i)          this
paragraph (c) does not limit the effect of paragraph (b) or (e) of this Section 7.01;

 

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

 

    	 	 92	 

     

    

 

(iii)        the
Trustee will not be liable with respect to any action it takes or
omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05
hereof.

 

(d)          Whether
or not therein expressly so provided, every provision
of this Indenture or the other Note Documents that in any way relates to the Trustee
is subject to paragraphs (a), (b), (c),
(e) and (f) of this Section 7.01.

 

(e)          No
provision of this Indenture or the other Note Documents will require the Trustee to expend or risk its own funds or incur any liability,
financial or otherwise, in the performance of its duties hereunder or thereunder, or in the exercise of any of its powers if it
shall have reasonable grounds for believing that repayment or indemnity satisfactory to it against such risk or liability is not
assured to it. The Trustee will be under no obligation to exercise any of its rights and powers under this Indenture or the other
Note Documents at the request or direction of any Holders, unless such Holder has offered to the Trustee security and indemnity
reasonably satisfactory to it against any loss, liability or expense.

 

(f)           The
Trustee will not be liable for interest on any money received by it except as the Trustee
may agree in writing with the Issuer. Money held in trust by the Trustee
need not be segregated from other funds except to the extent required by law.

 

Section
7.02         Rights of Trustee.

 

(a)          The
Trustee may conclusively rely and will be protected in acting or refraining from acting,
upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document (whether in original, electronic or facsimile form) believed by
it to be genuine and to have been signed or presented by the proper Person.
The Trustee need not investigate any fact or matter
stated in any such resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order,
bond, debenture, note, other evidence of indebtedness or other paper or document.

 

(b)          Before
the Trustee acts or refrains from acting, it may
require an Officers’ Certificate or an Opinion of
Counsel or both, in each case that conforms to Section 12.05. The Trustee will not
be liable for any action it takes or omits to take in good faith in reliance on such Officers’
Certificate or Opinion of Counsel. The Trustee may consult with counsel of its own
selection and the advice of such counsel or any Opinion
of Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered
or omitted by it hereunder in good faith and in reliance thereon.

 

(c)          The
Trustee may act through its attorneys and agents and will
not be responsible for the misconduct or negligence of any agent
appointed with due care.

 

(d)          The
Trustee will not be liable for any action it takes or omits
to take in good faith that it believes to be authorized or within the rights or
powers conferred upon it by this Indenture or the other Note Documents (including,
without limitation, in its capacities hereunder or thereunder as Collateral Trustee, Custodian, Registrar, Paying Agent, and Parity
Lien Representative).

 

    	 	 93	 

     

    

 

(e)          Unless
otherwise specifically provided in this Indenture,
any demand, request, direction or notice from the Issuer
will be sufficient if signed by an Officer of the Issuer.

 

(f)          The
Trustee will be under no obligation to exercise any of the rights or
powers vested in it by this Indenture or the other Note Documents at the request
or direction of any of the Holders unless such Holders
have offered to the Trustee reasonable indemnity or
security satisfactory to it against the losses, liabilities and expenses that might be incurred by it in compliance with
such request or direction.

 

(g)          The
Trustee shall not be deemed to have notice of a Default
or an Event of Default (i) except any Default
or Event of Default as to which the Trustee shall have received written notification from the Issuer at the Corporate Trust Office
of the Trustee, which such notice shall reference the Notes and this Indenture and state that such notice is a “notice of
default” or (ii) unless a Responsible Officer of the Trustee who is charged with administration of this Indenture has actual
knowledge of such Default or Event of Default but such actual knowledge shall not include receipt of information obtained in any
report or other documents furnished under Section 4.03 of this Indenture, which reports and documents the Trustee shall have no
duty to examine. 

 

The Collateral Trustee shall not be deemed
to have knowledge or notice of the occurrence of any Default or Event of Default, unless an Officer of the Collateral Trustee shall
have received written notice of the same referring to the Notes and this Indenture, describing such Default or Event of Default
and stating that such notice is a “notice of default.” The Collateral Trustee shall take such action with respect to
such Default or Event of Default as may be requested by the Trustee. After the occurrence of an Event of Default, the Trustee,
acting in accordance with the terms of this Indenture, may direct the Collateral Trustee in connection with any action required
or permitted by this Indenture or the other Note Documents.

 

(h)          No
provision of this Indenture will require the Trustee to expend or risk its own funds or otherwise incur any financial liability
in the performance of its duties hereunder, or in the exercise of its rights or powers, unless it is offered reasonable security
or indemnity against any loss, liability or expense.

 

(i)          In
no event shall the Trustee be responsible or liable for special, indirect, punitive, or consequential loss or damage of any kind
whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood
of such loss or damage and regardless of the form of action.

 

(j)          The
rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its rights to be
indemnified and exculpated, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder and under
the other Note Documents (including, without limitation, as Collateral Trustee, Custodian, Registrar, Paying Agent, and Parity
Lien Representative), and each agent, custodian and other Person employed to act hereunder.

 

    	 	 94	 

     

    

 

(k)          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.

 

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

 

(m)          The
permissive rights of the Trustee to take certain actions under this Indenture shall not be construed as a duty unless so specified
herein.

 

Section
7.03         Individual Rights of Trustee.

 

The Trustee, in its individual or any other
capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the
same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as
defined in the TIA) after a Default has occurred and is continuing it must eliminate such conflict within 90 days or resign. Any
Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

 

Section
7.04         Trustee’s Disclaimer.

 

The
Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the other Note
Documents, it shall not be accountable for the Issuer’s use of the proceeds from the Notes or any money paid to the Issuer
or upon the Issuer’s direction under any provision of this Indenture, it will not be responsible for the use or application
of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein,
in the other Note Documents or in any other document in connection with the issuance of the Notes or pursuant to this Indenture
or the other Note Documents other than its certificate of authentication. The Trustee makes no representation as to, and will not
be responsible for, (i) the existence, genuineness, validity, sufficiency, value or condition of any Collateral or other property
covered or intended to be covered by the Parity Lien of the Security Documents or any part thereof, or the title of the Grantors
thereto, (ii) the security or the adequacy of such security afforded by the Security Documents or hereby, or (iii) the validity,
perfection, priority or enforceability of the Parity Liens in any of the Collateral. The Trustee will not be responsible for insuring
the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance
of the Collateral. The Trustee shall be under no obligation to ascertain or to inquire as to the observance or performance of any
of the agreements contained in, or conditions of, this Indenture or the other Note Documents or to inspect the properties, books,
or records of the Issuer, the Guarantors, or any of their respective affiliates. 

 

Section
7.05         Notice of Defaults.

 

If a Default or Event of Default occurs
and is continuing and if the Trustee has knowledge thereof (within the meaning of Section 7.02(g) hereof), the Trustee will
provide a notice of the Default or Event of Default to the Holders of the Notes within 90 days after it occurs, unless prior to
the provision of such notice by the Trustee, such Default or Event of Default has been cured and the Trustee receives notice from
the Issuer of such cure. Except in the case of a Default or Event of Default in payment of principal of, or premium or interest,
if any, on, any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interests of the Holders of the Notes.

Section
7.06         [Reserved].

 

Section
7.07         Compensation and Indemnity.

 

(a)          The
Issuer shall pay to the Trustee from time to time
reasonable compensation for its acceptance of this Indenture and services hereunder and
under the other Note Documents as the Issuer and the Trustee shall agree in writing from time to time. The Trustee’s
compensation will not be limited by any law on compensation of a trustee
of an express trust. The Issuer shall reimburse the Trustee
promptly upon request for all reasonable disbursements, advances and expenses incurred or
made by it in addition to the compensation for its services. Such expenses will include
the reasonable compensation, disbursements and expenses of the Trustee’s agents and
counsel.

 

(b)          The
Issuer and the Guarantors will indemnify the Trustee
(which for purposes of this Section 7.07 shall include each of its officers, directors, employees, agents, advisors, and representatives)
for, and hold it harmless against, any and all losses, liabilities, claims, damages or expenses
(including attorneys’ fees and expenses) incurred by it arising out of or in connection
with the acceptance or administration of this trust and the performance of its duties under
this Indenture and the other Note Documents, including the costs and expenses of enforcing
this Indenture and the other Note Documents against the Issuer
and the Guarantors (including this Section 7.07)
and defending itself against any claim (whether asserted by the Issuer, the Guarantors,
any Holder or any other Person) or
liability in connection with the exercise or performance of any of its powers or
duties hereunder or the other Note Documents, except to the extent any such loss, liability or
expense may be attributable to its gross negligence, bad faith or willful misconduct
as determined by a final order by a court of competent jurisdiction. The Trustee will notify
the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee
to so notify the Issuer will not relieve the Issuer
or any of the Guarantors of their obligations hereunder.
The Issuer and the Guarantors shall defend the claim,
and the Trustee will reasonably cooperate in the defense. The Trustee
may have separate counsel, and the Issuer shall pay the reasonable fees and expenses
of such counsel. Neither the Issuer nor any Guarantor need
pay for any settlement made without its consent, which consent shall not be unreasonably
withheld.

 

(c)          The
obligations of the Issuer and the Guarantors
under this Section 7.07 will survive
the satisfaction and discharge of this Indenture or the removal or resignation of the Trustee.

 

(d)          To
secure the Issuer’s and the Guarantors’
payment obligations in this Section 7.07,
the Trustee will have a Lien prior to the Notes
on all money or property held or collected
by the Trustee, except that held in trust to pay principal
of, or premium or interest, if any, on, particular Notes. Such Lien
will survive the satisfaction and discharge of this Indenture.

 

    	 	 96	 

     

    

 

(e)          When
the Trustee incurs expenses or renders services after
an Event of Default specified in Section 6.01(h)
or (i) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its
agents and counsel) are intended to constitute expenses of administration under any Bankruptcy
Law.

 

Section
7.08         Replacement of Trustee.

 

(a)          A
resignation or removal of the Trustee and appointment
of a successor Trustee will become effective only upon the successor Trustee’s
acceptance of appointment as provided in this Section 7.08.

 

(b)          The
Trustee may resign in writing at any time and be discharged from the trust hereby created
by so notifying the Issuer. The Holders of a majority in
aggregate principal amount of the then outstanding Notes may remove the Trustee by
so notifying the Trustee and the Issuer in writing.
The Issuer may remove the Trustee if:

 

(i)          the
Trustee fails to comply with Section 7.10
hereof;

 

(ii)         the
Trustee is adjudged a bankrupt or an insolvent or
an order for relief is entered with respect to the Trustee under any Bankruptcy
Law;

 

(iii)        a
custodian or public officer takes charge of the Trustee
or its property; or

 

(iv)        the
Trustee becomes incapable of acting.

 

(c)          If
the Trustee resigns or is removed or
if a vacancy exists in the office of Trustee for any reason, the Issuer
will promptly appoint a successor Trustee. Within one year after the successor Trustee
takes office, the Holders of a majority in aggregate principal amount of the then outstanding
Notes may appoint a successor Trustee to replace the successor Trustee
appointed by the Issuer.

 

(d)          If
a successor Trustee does not take office within 60 days after the retiring Trustee
resigns or is removed, the retiring Trustee (at the
Issuer’s expense), the Issuer, or the
Holders of at least 10% in aggregate principal amount of
the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

 

(e)          If
the Trustee, after written request by any Holder who
has been a Holder for at least six months, fails to comply with Section 7.10
hereof, such Holder may petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor Trustee.

 

(f)          A
successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee
and to the Issuer. Thereupon, the resignation or
removal of the retiring Trustee will become effective, and the successor Trustee
will have all the rights, powers and duties of the Trustee under this Indenture.
The successor Trustee will provide a notice of its succession to Holders.
The retiring Trustee will promptly transfer all property
held by it as Trustee to the successor Trustee;
provided all sums owing to the Trustee hereunder
have been paid and subject to the Lien provided for in Section 7.07
hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08,
the Issuer’s obligations under Section 7.07
hereof will continue for the benefit of the retiring Trustee.

Section
7.09         Successor Trustee by Merger,
etc.

 

If the Trustee consolidates, merges or converts
into, or transfers all or substantially all of its corporate trust business to, another corporation, banking association or trust
company, the successor corporation, national banking association or trust company without any further act will be the successor
Trustee.

 

Section
7.10         Eligibility; Disqualification.

 

There will at all times be a Trustee hereunder
that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that
is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or
state authorities and that has a combined capital and surplus of at least $100.0 million as set forth in its most recent published
annual report of condition.

References to the Trustee in Sections 6.10,
7.01, 7.02, 7.03, 7.04, 7.07 and 7.08 shall be understood to include the Trustee when acting in other capacities under the Note
Documents, including, without limitation, as Collateral Trustee, Registrar, Custodian, Paying Agent and Parity Lien Representative.
Without limiting the foregoing, and for the avoidance of doubt, such Sections shall be read to apply to the Collateral Trustee
and the Security Documents, mutatis mutandis, in addition to this Indenture. The privileges, rights, indemnities and exculpatory
provisions contained in this Indenture shall apply to the Trustee, wherever it is acting in any capacity under this Indenture and
the other Note Documents, and shall survive satisfaction and discharge or the termination for any reason of this Indenture or any
other Note Document and the resignation or removal of the Trustee.

 

Article
VIII.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

 

Section
8.01         Option to Effect Legal Defeasance or
Covenant Defeasance.

 

The Issuer may at any time, at the option
of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, elect to have either Section
8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this
Article VIII.

 

    	 	 98	 

     

    

 

Section
8.02         Legal Defeasance and Discharge.

 

Upon the Issuer’s exercise under Section
8.01 hereof of the option applicable to this Section 8.02, the Issuer and each of the Guarantors will, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations
with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied
(hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer and the Guarantors
will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees),
which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other
Sections of this Indenture referred to in clauses (a) and (b) below, and to have satisfied all their other obligations under such
Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper
instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged
hereunder:

 

(a)          the
rights of Holders of outstanding Notes to receive
payments in respect of the principal of, or premium or interest, if any, on, such Notes
when such payments are due from the trust referred to in Section 8.04
hereof;

 

(b)          the
Issuer’s obligations with respect to such Notes
under Article II and Section 4.02
hereof;

 

(c)          the
rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuer’s
and the Guarantors’ obligations in connection
therewith; and

 

(d)          this
Article VIII.

 

Subject to compliance with this Article
VIII, the Issuer may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under
Section 8.03 hereof.

 

Section
8.03         Covenant Defeasance.

 

Upon the Issuer’s exercise under Section
8.01 hereof of the option applicable to this Section 8.03, the Issuer and each of the Guarantors will, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their respective obligations under
the covenants contained in Sections 3.09, 4.03, 4.05, 4.07, 4.08, 4.09, 4.10,
4.11, 4.12, 4.13, 4.14 (as it relates to any Restricted Subsidiary of the Issuer), 4.15, 4.16,
and 4.17 hereof and clause (4) of Section 5.01(a) hereof with respect to the outstanding Notes on and after the date
the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and
the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration
or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding”
for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes to
the extent permitted by GAAP). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note
Guarantees, the Issuer and the Guarantors may omit to comply with and will have no liability in respect of any term, condition
or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any
such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such
omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified
above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Issuer’s
exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of
the conditions set forth in Section 8.04 hereof, Section 6.01(c), (d), (e), (f), (g)
and (j) hereof will not constitute Events of Default.

 

    	 	 99	 

     

    

 

Section
8.04         Conditions to Legal or Covenant
Defeasance.

 

In order to exercise either Legal Defeasance
or Covenant Defeasance under either Sections 8.02 or 8.03 hereof:

 

(a)          the
Issuer must irrevocably deposit with the Trustee,
in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable Government
Securities, or a combination thereof, in such amounts as will
be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or
firm of independent public accountants, to pay the principal of, premium on, if any, and interest, if any, on, the outstanding
Notes on the stated date for payment thereof or on the applicable redemption date,
as the case may be, and the Issuer must specify whether the Notes
are being defeased to such stated date for payment or to a particular redemption
date;

 

(b)          in
the case of an election under Section 8.02 hereof,
the Issuer must deliver to the Trustee an Opinion
of Counsel reasonably acceptable to the Trustee confirming that:

 

(i)          the
Issuer has received from, or there has been published
by, the Internal Revenue Service a ruling; or

 

(ii)         since
the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based
thereon such Opinion of Counsel will confirm that, the Holders of the outstanding
Notes will not recognize income, gain or loss for federal income tax purposes as
a result of such Legal Defeasance and will be subject
to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal
Defeasance had not occurred;

 

(c)          in
the case of an election under Section 8.03 hereof,
the Issuer must deliver to the Trustee an Opinion
of Counsel reasonably acceptable to the Trustee confirming that the Holders
of the outstanding Notes will not recognize income, gain or
loss for federal income tax purposes as a result of such Covenant Defeasance and
will be subject to federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such Covenant Defeasance had not occurred;

 

(d)          no
Default or Event of Default has occurred and is continuing
on the date of such deposit (other than a Default or Event of Default
resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other
Indebtedness), and the granting of Liens to secure
such borrowings);

 

(e)          such
Legal Defeasance or Covenant Defeasance will not result in a breach or
violation of, or constitute a default under,
any material agreement or instrument (other than this Indenture
and the agreements governing any other Indebtedness being defeased, discharged or
replaced) to which the Issuer or any of its Subsidiaries
is a party or by which the Issuer or any of
its Subsidiaries is bound;

 

    	 	 100	 

     

    

 

(f)          the
Issuer must deliver to the Trustee an Officers’
Certificate stating that the deposit was not made by the Issuer with the intent of
preferring the Holders of the Notes over the other
creditors of the Issuer with the intent of defeating, hindering, delaying or
defrauding any creditors of the Issuer or others; and

 

(g)          the
Issuer must deliver to the Trustee an Officers’
Certificate and an Opinion of Counsel, each stating that all conditions precedent
relating to the Legal Defeasance or the Covenant Defeasance
have been complied with.

 

Section
8.05         Deposited Money and Government Securities to be Held in Trust;
Other Miscellaneous Provisions.

 

Subject to Section 8.06 hereof, all
money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee,
collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof
in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such
Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as Paying Agent)
as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, or
premium or interest, if any, but such money need not be segregated from other funds except to the extent required by law.

 

The Issuer will pay and indemnify the Trustee
against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant
to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge
which by law is for the account of the Holders of the outstanding Notes.

 

Notwithstanding anything in this Article
VIII to the contrary, the Trustee will deliver or pay to the Issuer from time to time upon the request of the Issuer any money
or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which
may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required
to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

 

Section
8.06         Repayment to the Issuer.

 

Any money deposited with the Trustee or
any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, or premium or interest, if any, on,
any Note and remaining unclaimed for two years after such principal, or premium or interest, if any, has become due and payable
shall be paid to the Issuer on its request or (if then held by the Issuer) will be discharged from such trust; and the Holder of
such Note will thereafter be permitted to look only to the Issuer for payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, will thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of
the Issuer cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money
remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification
or publication, any unclaimed balance of such money then remaining will be repaid to the Issuer.

 

    	 	 101	 

     

    

 

Section
8.07         Reinstatement.

 

If the Trustee or Paying Agent is unable
to apply any U.S. dollars or non-callable Government Securities in accordance with Sections 8.02 or 8.03 hereof,
as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the Issuer’s and the Guarantors’ obligations under this Indenture and the Notes
and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Sections 8.02 or 8.03
hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Sections 8.02
or 8.03 hereof, as the case may be; provided, however, that, if the Issuer makes any payment of principal
of, or premium or interest, if any, on, any Note following the reinstatement of its obligations, the Issuer will be subrogated
to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

cure any ambiguity, defect or inconsistency;

 

(b)          to
provide for uncertificated Notes in addition to or in
place of certificated Notes;

substantially all of the Issuer’s or such
Guarantor’s properties or assets, as applicable;

of any Holder;

 

(e)          [reserved];

 

(f)          to
conform the text of the Note Documents or any other such documents (in recordable form)
as may be necessary or advisable to preserve and confirm the relative priorities of the
Priority Lien Documents and the Parity Lien Documents as
such priorities are contemplated by and set forth in the Intercreditor Agreement;

 

    	 	 102

Further, the Security Documents may be amended

security documents creating Priority Liens (“Priority Security Amendments”); provided, that such Priority Security
Amendments do not affect the Trustee’s or the Collateral Trustee’s own rights, duties or immunities under such Security
Documents. Promptly upon the effectiveness of such Priority Security Amendments, the Issuer shall deliver, and the Trustee and
the Collateral Trustee shall be entitled to rely upon, an Officers’ Certificate and an Opinion of Counsel certifying (i)
as to the effectiveness of such Priority Security Amendments and (ii) that, pursuant to this Section 9.01, the Security Documents

shall be deemed to have notice or knowledge of any Priority Security Amendments until it has received such Officers’ Certificate
and Opinion of Counsel as provided herein.

 

    	 	 103	 

     

    

 

In addition, the Trustee and the Collateral
Trustee shall be entitled to rely upon an Officers’ Certificate and an Opinion of Counsel certifying that Parity Lien Obligations

Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or
exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default
or Event of Default (other than a Default or Event of Default in the payment of the principal of, or premium or interest, if any,
on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision
of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate
principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class
(including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the
Notes), in each case in addition to any required consent of holders of other Parity Lien Obligations required with respect to any
amendment or waiver under any Note Document. Section 2.08 hereof shall determine which Notes are considered to be “outstanding”
for purposes of this Section 9.02. However, without the consent of each Holder affected, an amendment, supplement or waiver
under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

 

(a)          reduce
the principal amount of Notes whose Holders must
consent to an amendment, supplement or waiver;

 

(b)          reduce
the principal of or change the fixed maturity of any Note
or alter or waive any of the provisions with respect to the redemption or
repurchase of the Notes (other than provisions under Sections 3.09,
4.10 or 4.15);

 

(c)          reduce
the rate of or change the time for payment of interest, including default
interest, on any Note;

 

(d)          waive
a Default or Event of Default in the
payment of principal of, or premium or interest, if any, on the Notes (except a rescission
of acceleration of the Notes by the Holders of a majority
in aggregate principal amount of the then outstanding Notes and a waiver of the payment
default that resulted from such acceleration);

 

(e)          make
any Note payable in money other than that stated in the Notes;

 

    	 	 104	 

     

    

 

(f)          make
any change in the provisions of this Indenture relating to waivers of past Defaults
or the rights of Holders of the Notes to receive
payments of principal of, or premium or interest, if any, on, the Notes
(other than as permitted in clause (g) below);

 

(g)          waive
a redemption or repurchase payment with respect to any Note
(other than a payment required by Sections 3.09, 4.10 or
4.15);

 

(h)          release
any Guarantor from any of its obligations under its
Note Guarantee or this Indenture, except in accordance
with the terms of this Indenture;

 

(i)          make
any change in the preceding amendment, supplement and waiver provisions;

 

(j)          make
any change to the ranking or modify the ranking of the Notes
or Note Guarantees that would adversely affect the Holders; or

 

(k)          make
any change to the consent of Holders of Notes required to release the Liens
for the benefit of the Holders on all, substantially all or any part of the Collateral,
other than in accordance with the Note Documents.

 

In addition, any amendment to, or waiver
of, the provisions of this Indenture or any Security Document that has the effect of releasing all or substantially all of the
Collateral from the Liens securing the Notes (other than in accordance with the Note Documents) will require the consent of the
Holders of at least 66-2/3% in aggregate principal amount of the Notes then outstanding.

 

Upon the request of the Issuer accompanied
by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the
filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of the Notes as aforesaid, and upon
receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee will join with the Issuer and the
Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects
the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion,
but will not be obligated to, enter into such amended or supplemental indenture.

 

The consent of the Holders
is not necessary under this Section 9.02 to
approve the particular form of any proposed amendment, supplement or waiver. It is sufficient
if such consent approves the substance of the proposed amendment, supplement or waiver.
After an amendment, supplement or waiver under this Indenture
requiring the approval of the Holders becomes effective, the Issuer
will mail to the Holders a notice briefly describing the amendment, supplement or
waiver. However, the failure to give such notice, or any defect in the notice, will
not impair or affect the validity of the amendment, supplement or
waiver.

Section
9.03         [Reserved.]

 

Section
9.04         Revocation and Effect of Consents.

 

Until an amendment, supplement or waiver
becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder
of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent
is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note
if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An
amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

 

Section
9.05         Notation on or Exchange of
Notes.

 

The Trustee may place an appropriate notation
about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in exchange for all Notes may issue and
the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

 

Failure to make the appropriate notation
or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver.

 

Section
9.06         Trustee and Collateral Trustee to Sign Amendments, etc.

 

The Trustee and the Collateral Trustee will
sign any amended or supplemental indenture authorized pursuant to this Article IX if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee or the Collateral Trustee, as applicable. In executing
any amended or supplemental indenture, the Trustee and the Collateral Trustee will be entitled to receive and (subject to Section
7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Section 12.04 hereof,
an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture and the other Note Documents and that such amendment, supplement or waiver is the legal,
valid and binding obligation of the Issuer and any Guarantors party thereto, enforceable against them in accordance with its terms,
subject to customary exceptions, and such amendment, supplement or waiver complies with the provisions hereof.

 

Article
X.

NOTE GUARANTEES

 

Section
10.01         Guarantee.

 

(a)          Subject
to this Article X, each of the Guarantors hereby,
jointly and severally, unconditionally Guarantees to each Holder
of a Note authenticated and delivered by the Trustee
and to the Trustee and its successors and assigns, irrespective of the validity and
enforceability of this Indenture, the Notes or the
obligations of the Issuer hereunder or
thereunder, that:

 

    	 	 106	 

     

    

 

(i)          the
principal of, or premium or interest, if any, on, the Notes will be promptly paid
in full when due, whether at stated maturity, by acceleration, redemption or
otherwise, and interest on the overdue principal of, or premium or interest, if any, on,
the Notes, if lawful, and all other obligations of
the Issuer to the Holders or the Trustee
hereunder or thereunder will be promptly paid
in full or performed, all in accordance with the terms hereof and thereof; and

 

(ii)         in
case of any extension of time of payment or renewal of any Notes
or any of such other obligations, that same will
be promptly paid in full when due or performed in accordance with the terms of the
extension or renewal, whether at stated maturity,
by acceleration or otherwise.

 

Failing payment when due of any amount so
Guaranteed or any performance so Guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay
the same immediately. Each Guarantor agrees that this is a Guarantee of payment and not a Guarantee of collection.

 

(b)          The
Guarantors hereby agree that their obligations hereunder
are unconditional, irrespective of the validity, regularity or enforceability of the Notes
or this Indenture, the absence of any action to enforce the same, any waiver or
consent by any Holder of the Notes with respect
to any provisions hereof or thereof, the recovery of any judgment against the Issuer,
any action to enforce the same or any other circumstance which might otherwise constitute
a legal or equitable discharge or defense of a guarantor.
Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims
with a court in the event of insolvency or bankruptcy of the Issuer,
any right to require a proceeding first against the Issuer, protest, notice and all demands
whatsoever and covenant that this Note Guarantee will not be discharged except by complete
performance of the obligations contained in the Notes and
this Indenture.

 

(c)          If
any Holder or the Trustee is required by any court
or otherwise to return to the Issuer, the Guarantors
or any custodian, trustee, liquidator or
other similar official acting in relation to either the Issuer or the Guarantors,
any amount paid by any of them to the Trustee or such Holder,
this Note Guarantee, to the extent theretofore discharged, will
be reinstated in full force and effect.

 

(d)          Each
Guarantor agrees that it will not be entitled to
any right of subrogation in relation to the Holders in respect of any obligations
Guaranteed hereby until payment in full of all obligations Guaranteed hereby. Each
Guarantor further agrees that, as between the Guarantors,
on the one hand, and the Holders and the Trustee,
on the other hand, (i) the maturity of the obligations Guaranteed hereby may be accelerated
as provided in Article VI
hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the obligations
Guaranteed hereby, and (ii) in the event of any declaration of acceleration of such obligations
as provided in Article VI
hereof, such obligations (whether or not due
and payable) will forthwith become due and payable by the Guarantors
for the purpose of this Note Guarantee. The Guarantors
will have the right to seek contribution from any non-paying Guarantor so long as
the exercise of such right does not impair the rights of the Holders under the Note
Guarantee.

 

    	 	 107	 

     

    

 

Section
10.02         Limitation on Guarantor Liability.

 

Each Guarantor and, by its acceptance of
Notes, each Holder hereby confirm that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute
a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent
Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention,
the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to
the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such
Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from
or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article
X, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

 

Section
10.03         Execution and Delivery of Note
Guarantee.

 

To evidence its Note Guarantee set forth
in Section 10.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form attached
as Exhibit E hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee
and that this Indenture, or a supplement thereto, will be executed on behalf of such Guarantor by one of its Officers.

 

Each Guarantor hereby agrees that its Note
Guarantee set forth in Section 10.01 hereof will remain in full force and effect notwithstanding any failure to endorse
on each Note a notation of such Note Guarantee.

 

If an Officer whose signature is on the
notation of its Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which such notation
of its Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless.

 

The delivery of any Note by the Trustee,
after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in this Indenture on behalf
of the Guarantors.

 

In the event that the Issuer or any of its
Restricted Subsidiaries creates or acquires any Restricted Subsidiary after the Issue Date, if required by Section 4.16
hereof, the Issuer will cause such Restricted Subsidiary to comply with the provisions of Section 4.16 hereof and this Article
X, to the extent applicable.

 

Section
10.04         Guarantors May Consolidate,
etc., on Certain Terms.

 

No Guarantor may sell or otherwise dispose
of, in one or more related transactions, all or substantially all of its properties or assets to, or consolidate with or merge
with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Issuer or another Guarantor,
unless:

 

    	 	 108	 

     

    

 

(a)          immediately
after giving effect to such transaction or series of transactions, no Default or Event of
Default exists;

 

(b)          either:

 

(i)          the
Person acquiring the properties or assets in any
such sale or other disposition or the Person
formed by or surviving any such consolidation or
merger (if other than the Guarantor) unconditionally assumes all the obligations
of that Guarantor under its Note Guarantee and
this Indenture pursuant to a supplemental indenture in
form reasonably satisfactory to the Trustee; or

 

(ii)         such
transaction or series of transactions does not violate Section 4.10
hereof; and

 

(c)          if
the Person formed by or surviving any such consolidation or
merger, if applicable, is a Restricted Subsidiary of the Issuer, then such Person
shall take such action (or agree to take such action) as may be necessary to cause
any property or assets that constitute Collateral owned
by or transferred to such Person to be subject to
the Parity Liens in the manner and to the extent required under the Note
Documents and shall deliver an Opinion of Counsel as to the enforceability of any
amendments, supplements or other instruments with respect to the Note
Documents to be executed, delivered, filed and recorded, as applicable, and such other matters as the Trustee
or Collateral Trustee, as applicable, may reasonably request.

 

In case of any such consolidation, merger,
sale or other disposition and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to
the Trustee and satisfactory in form to the Trustee, of the Note Guarantee of the Guarantor and the due and punctual performance
of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to
and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person
thereupon may cause to be signed any or all of the notations of Note Guarantees to be endorsed upon all of the Notes issuable hereunder
which theretofore shall not have been signed by the Issuer and delivered to the Trustee. All the Note Guarantees so issued will
in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued
in accordance with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution
hereof.

 

Section
10.05         Releases.

 

The Note Guarantee of a Guarantor shall
be released:

 

(a)          
in connection with any sale or other disposition of all or
substantially all of the properties or 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 Issuer
or a Restricted Subsidiary of the Issuer, if the sale or
other disposition does not violate Section 4.10
hereof;

 

(b)          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 Issuer
or a Restricted Subsidiary of the Issuer, if the sale or
other disposition does not violate Section 4.10
hereof and such Guarantor ceases to be a Restricted
Subsidiary of the Issuer as a result of the sale or
other disposition;

 

    	 	 109	 

     

    

 

(c)          upon
designation of any Restricted Subsidiary that is a Guarantor
as an Unrestricted Subsidiary in accordance with the terms of this Indenture;

 

(d)          upon
Legal Defeasance or Covenant Defeasance in accordance with Article VIII
hereof or satisfaction and discharge of this Indenture
in accordance with Article XI hereof;

 

(e)          upon
the liquidation or dissolution of such Guarantor provided
no Default or Event of Default has occurred
that is continuing;

 

(f)          at
such time as such Guarantor ceases both (a) to Guarantee
any other Indebtedness of the Issuer and any
Indebtedness of any other Guarantor (except as a
result of payment under any such other Guarantee) and (b) to be an obligor
with respect to any Indebtedness under any Credit
Facility; or

 

(g)          upon
such Guarantor consolidating with, merging into or transferring
all of its properties or assets to the Issuer or another
Guarantor, and as a result of, or in connection with,
such transaction such Guarantor dissolving or otherwise
ceasing to exist.

 

Any Guarantor not released from its obligations
under its Note Guarantee as provided in this Section 10.05 will remain liable for the full amount of principal of, or premium
or interest, if any, on, the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article
X.

 

Article
XI.

SATISFACTION AND DISCHARGE

 

Section
11.01         Satisfaction and Discharge.

 

This Indenture will be discharged and will
cease to be of further effect as to all Notes issued hereunder, when:

 

(a)          either:

 

(1)         all
Notes that have been authenticated, except lost, stolen or
destroyed Notes that have been replaced or paid
and Notes for whose payment money has been deposited in trust and thereafter repaid to the
Issuer, have been delivered to the Trustee for cancellation;
or

 

(2)         all
Notes that have not been delivered to the Trustee for
cancellation have become due and payable by reason of the mailing of a notice of redemption or
otherwise or will become due and payable within one year and either the Issuer
or any Guarantor has irrevocably deposited or caused
to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders,
cash in U.S. dollars, non-callable Government Securities, or
a combination thereof, in such amounts as will be sufficient, without consideration
of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes
not delivered to the Trustee for cancellation for principal, or
premium, if any, or interest, if any, to the date of Stated
Maturity or redemption;

 

    	 	 110	 

     

    

 

(b)          in
respect of subclause (2) of clause (a) of this Section
11.01, no Event of Default
has occurred and is continuing on the date of the deposit (other than an Event
of Default resulting from the borrowing of funds to be applied to such deposit and
any similar deposit relating to other Indebtedness and, in each case, the granting of Liens
to secure such borrowings) and the deposit will not result in a breach or
violation of, or constitute a default under,
any other instrument to which the Issuer or any Guarantor
is a party or by which the Issuer or any Guarantor
is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect
such satisfaction and discharge and any similar concurrent deposit relating to other Indebtedness,
and in each case the granting of Liens to secure such borrowings);

 

(c)          the
Issuer has paid or caused to be paid all other sums
payable by the Issuer under this Indenture and the other
Note Documents; and

 

(d)          the
Issuer has delivered irrevocable instructions to the Trustee
to apply the deposited money toward the payment of the Notes at Stated
Maturity or on the redemption date, as the case may be.

 

In addition, the Issuer must deliver an
Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and
discharge have been satisfied.

 

Notwithstanding the satisfaction and discharge
of this Indenture, if funds have been deposited with the Trustee pursuant to subclause (2) of clause (a) of this Section 11.01,
the provisions of Section 11.02 and Section 8.06 hereof will survive. In addition, nothing in this Section 11.01
will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and
discharge of this Indenture.

 

Section
11.02         Application of Trust Money.

 

Subject to the provisions of Section
8.06 hereof, all funds deposited with the Trustee pursuant to Section 11.01 hereof shall be held in trust 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, or premium, if any, or interest, if any, for whose payment such money has been deposited with the Trustee; but such
funds need not be segregated from other funds except to the extent required by law.

 

If the Trustee or Paying Agent is unable
to apply any money or Government Securities in accordance with Section 11.01 hereof by reason of any legal proceeding or
by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such
application, the Issuer’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated
as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Issuer has made any payment
of principal of, or premium or interest, if any, on, any Notes because of the reinstatement of its obligations, the Issuer shall
be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by
the Trustee or Paying Agent.

the Guarantees and performance of all other obligations
of the Issuer and the Guarantors to the Holders

Documents, according to the terms hereunder or thereunder, are secured, as provided
in the Security Documents. The Issuer and
each of the Guarantors consent and agree to be bound by the terms of the Security
Documents to which they are parties, as the same may be in effect from time to time, and agree to perform their obligations
thereunder in accordance therewith. The Issuer and the Guarantors
hereby agree that the Collateral Trustee shall hold the Collateral
(directly or through co-trustees or agents)
on behalf of and for the benefit of all of the Holders and the other holders of Parity
Lien Obligations and the Trustee, in each case, pursuant to the terms of this Indenture, the Security Documents and the Intercreditor
Agreement.

 

(b)          Each
Holder, by its acceptance of the Notes and of the
Guarantees, consents and agrees to the terms of the Intercreditor

providing for the subordination of Liens, the foreclosure and release of Collateral and
amendments to the Security Documents) as the same may be in effect or
may be amended from time to time in accordance with their terms and authorizes and appoints Delaware Trust Company

Each Holder and the Trustee hereby authorize and appoint Delaware Trust Company as Collateral
Trustee and each Holder and the Trustee authorize and direct the Collateral Trustee to enter
into the Security Documents (including any amendments thereto contemplated by Section 7.1
of the Collateral Trust Agreement and any security documents
to secure additional Parity Lien Debt in accordance with Section 3.8 of the Collateral
Trust Agreement) and the Intercreditor Agreement and to perform its obligations and
exercise its rights thereunder in accordance therewith, subject to the terms and conditions thereof, including, without limitation,
the limitations on duties of the Collateral Trustee provided in Section 5.12 of the Collateral
Trust Agreement. The Trustee, the Collateral Trustee
and each Holder, by accepting the Notes and
the Guarantees of the Guarantors, acknowledges that,
as more fully set forth in the Security Documents, the Collateral
as now or hereafter constituted shall be held for the benefit of all the holders
of Parity Lien Obligations, subject to the Intercreditor
Agreement, the Collateral Trustee and the Trustee,
and the Lien of this Indenture and the Security
Documents is subject to and qualified and limited in all respects by the Intercreditor Agreement,
the Security Documents and actions that may be taken thereunder.

 

Section
13.02         Post-Issue Date Collateral Requirements.

 

(a)          Within
30 days of the Issue Date, the Issuer shall, or
shall cause the applicable Guarantor to, (i) execute and deliver to the Collateral
Trustee, as mortgagee or beneficiary, as applicable, such Mortgages
or other Security Documents, and any supplements or
amendments related thereto, together with satisfactory evidence of the completion (or satisfactory
arrangements for the completion) of all recordings and filings of such Mortgages or other
Security Documents in the proper recorders’ offices or
appropriate public records (and payment of any taxes or fees in connection therewith)
as may be necessary to create a valid, perfected second-priority Lien (subject to the Intercreditor
Agreement and to Permitted Collateral Liens), on or against the Collateral
that include not less than 80% of the Present Value of Proved Reserves held by the Issuer and the Restricted Subsidiaries, as evaluated
in Reserve Reports prepared by the Issuer or which the Issuer causes to be prepared as of each December 31 and June 30 and
(ii) on the date that each such Mortgage is so filed or
recorded, cause its counsel for the jurisdiction in which the relevant Oil and Gas Properties
are located to execute and deliver to the Collateral Trustee a favorable Opinion
of Counsel with respect thereto in form and substance reasonably satisfactory to the Collateral
Trustee.

 

    	 	 116	 

     

    

 

(b)          Any
Security Documents entered into after the Issue Date shall
be substantially in the form of the corresponding security document securing the Priority Liens,
or to the extent there is no such corresponding security document, the corresponding security
documents securing the Priority Lien Obligations in place on the Issue
Date, in each case, with such changes as are reasonably necessary to reflect the terms of the Intercreditor
Agreement and with such deletions or modifications of representations, warranties
and covenants as are customary with respect to security documents establishing Liens
securing publicly traded debt securities, all as certified to the Collateral Trustee pursuant
to an Officers’ Certificate and Opinion of Counsel.

 

Section
13.03         Further Assurances; Liens on
Additional Property.

 

(a)          The
Issuer and each of the Guarantors shall do or
cause to be done all acts and things that may be required, or that the Collateral Trustee from time to time as may reasonably
request, to assure and confirm that the Collateral Trustee holds, for the benefit of the
holders of Parity Lien Obligations, duly created and enforceable and perfected second priority
Liens upon the Collateral (subject to the Intercreditor
Agreement and Permitted Collateral Liens) (including any acquired Property or other
Property required by any Parity Lien Document to
become, Collateral after the Issue Date), in each
case, as contemplated by, and with the Lien priority required under, the Parity
Lien Documents, and in connection with any merger, consolidation or sale of assets
of the Issuer or any Guarantor, the property
and assets of the Person which is consolidated or
merged with or into the Issuer or any Guarantor,
to the extent that they are property or assets of the types which would constitute Collateral
under the Security Documents, shall be treated as after-acquired property
and such Issuer or such Guarantor shall take
such action as may be reasonably necessary to cause such property and assets to be made
subject to the Parity Liens, in the manner and to the extent required under the Parity
Lien Documents; provided, however, that this clause (a) shall not require delivery of any Mortgage unless, and then only
to the extent, required under clause (c) or (d) of this Section 13.03.

 

(b)          Upon
the request of the Collateral Trustee at any time and from time to time, the Issuer
and each of the Guarantors shall promptly execute, acknowledge and deliver such Security
Documents, instruments, certificates, financing statements, notices and other documents, and take such other actions as
shall be required, or that the Collateral Trustee may
reasonably (but shall have no duty to) request, to create, perfect, protect, assure or enforce
the Liens and benefits intended to be conferred, in each case as contemplated by the Parity
Lien Documents for the benefit of the holders of Parity Lien Obligations; provided
that no such Security Document, instrument or other
document shall be materially more burdensome upon the Issuer and the Guarantors
than the Parity Lien Documents executed and delivered (or
required to be executed and delivered promptly after the Issue Date, including pursuant to Section 13.2) by the Issuer
and the Guarantors in connection with the issuance of the Notes
on or about the Issue Date (it being understood
that the Collateral Trustee shall have no liability whatsoever to determine whether such
a document is materially burdensome and shall no liability whatever with respect to this determination).

 

    	 	 117	 

     

    

 

(c)          The
Issuer will deliver to the Trustee and Collateral Trustee
semi-annually on or before April 1 and October 1 in each calendar year, beginning
October 1, 2017, an Officers’ Certificate certifying that, as of the date of such
certificate, that the Collateral includes a valid and perfected Parity
Lien securing the Parity Lien Obligations on Oil
and Gas Properties that include not less than 80% of the Present Value of Proved
Reserves held by the Issuer and the Restricted Subsidiaries,
as evaluated in Reserve Reports prepared by the Issuer or
which the Issuer causes to be prepared as of each December 31 and June 30 (the “minimum
mortgage requirement”). In the event that such requirement is not satisfied, then the Issuer
shall, or shall cause the applicable Restricted Subsidiary
to, within sixty (60) days of delivery of such certificate, execute and deliver to the Collateral
Trustee: (i) such executed Mortgages or amendments or
supplements to prior Mortgages naming the Collateral
Trustee, as mortgagee or beneficiary, as may be necessary to cause the minimum
mortgage requirement to be satisfied, (ii) satisfactory evidence of the completion of all recordings and filings of such
Mortgages, amendments or supplements in the proper
recorders’ offices or appropriate public records (and payment of any taxes or
fees in connection therewith) and (iii) local counsel opinion or opinions (each,
subject to customary assumptions and qualifications) to the effect that the Collateral Trustee
has a valid and perfected Lien with respect to the Oil
and Gas Properties that are subject to the applicable Mortgage; provided
that (x) to the extent Mortgages have previously been recorded in the public records
of the state applicable to such additional Mortgages or amendments or
supplements to prior Mortgages and (y) the applicable local counsel opinion or
opinions had previously been delivered in connection with the filing of such mortgages,
no such opinion shall be required unless a corresponding opinion will be delivered to the
Priority Lien Collateral Agent.

 

(d)          The
Issuer will deliver to the Trustee copies of all
Security Documents delivered to the Collateral Trustee.

 

Section
13.04         Intercreditor Agreement.

 

This Article XIII and the provisions
of each other Security Document are subject to the terms, conditions and benefits set forth in the Intercreditor Agreement. The
Issuer and each Guarantor consents to, and agrees to be bound by, the terms of the Intercreditor Agreement, as the same may be
in effect from time to time, and to perform its obligations thereunder in accordance with the terms thereof. Each Holder, by its
acceptance of the Notes, (a) consents to the subordination of Liens provided for in the Intercreditor Agreement, (b) agrees that
it will be bound by, and will take no actions contrary to, the provisions of the Intercreditor Agreement and (c) authorizes and
instructs the Collateral Trustee on behalf of each Holder to enter into the Intercreditor Agreement as Second Lien Collateral Agent
(as defined in the Intercreditor Agreement) on behalf of such Holders as Second Lien Secured Parties (as defined in the Intercreditor
Agreement). In addition, each Holder authorizes and instructs the Collateral Trustee to enter into any amendments or joinders to
the Intercreditor Agreement in accordance with its terms with the consent of the parties thereto or otherwise in accordance with
its terms, without the consent of any Holder or the Trustee, to add additional Indebtedness as Priority Lien Debt or Parity Lien
Debt and add other parties (or any authorized agent or trustee therefor) holding such Indebtedness thereto and to establish that
the Lien on any Collateral securing such Indebtedness shall rank equally with the Liens on such Collateral securing the other Priority
Lien Debt or Parity Lien Debt, as applicable, then outstanding, to the extent permitted by the Secured Debt Documents. The Trustee
and the Collateral Trustee shall be entitled to rely upon an Officers’ Certificate and/or an Opinion of Counsel certifying
that any such amendment is authorized under the Note Documents. The foregoing provisions are intended as an inducement to the lenders
under the Credit Agreement to extend credit to the Issuer and certain of its Subsidiaries, and such lenders are intended third
party beneficiaries of such provisions and the provisions of the Intercreditor Agreement.

by its acceptance of the Notes, (a) agrees that it will be bound by, and will take no actions contrary to, the provisions of the
Collateral Trust Agreement and (b) authorizes and instructs the Collateral Trustee on behalf of the Holders of the Notes and each
other holder of Parity Lien Obligations to enter into the Collateral Trust Agreement as Collateral Trustee on behalf of such holders
of Parity Lien Obligations. In addition, each Holder authorizes and instructs the Collateral Trustee to enter into any amendments
or joinders to the Collateral Trust Agreement in accordance with its terms with the consent of the parties thereto or otherwise
in accordance with its terms, without the consent of any Holder or the Trustee, to add additional Indebtedness as Priority Lien
Debt or Parity Lien Debt and add other parties (or any authorized agent or trustee therefor) holding such Indebtedness thereto
and to establish that the Lien on any Collateral securing such Indebtedness shall rank equally with the Liens on such Collateral
securing the other Priority Lien Debt or Parity Lien Debt, as applicable, then outstanding, to the extent permitted by the Secured
Debt Documents. The Trustee and the Collateral Trustee shall be entitled to rely upon an Officers’ Certificate and/or an
Opinion of Counsel certifying that any such amendment is authorized under the Note Documents.

Lien Note due 2024

 

Capitalized terms used herein have the meanings
assigned to them in the Indenture referred to below unless otherwise indicated.

 

(1)         INTEREST.
Vanguard Natural Resources, Inc. (formerly known as VNR Finance Corp.), a Delaware corporation (the “Issuer”),
promises to pay or cause to be paid interest on the principal amount of this Note at 9.0% per annum from August 1, 2017 until maturity.
The Issuer will pay interest semi-annually in arrears on February 15 and August 15 of each year, or if any such day is not a Business
Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue
from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided
that, if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred
to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment
Date; provided further that the first Interest Payment Date shall be February 15, 2018. The Issuer will pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time
on demand at a rate that is 1% per annum higher than the then applicable interest rate on the Notes to the extent lawful; they
will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest,
if any (without regard to any applicable grace period), from time to time on demand at the same rate to the extent lawful.

 

Interest will be computed on the
basis of a 360-day year comprised of twelve 30-day months.

 

(2)         METHOD
OF PAYMENT. The Issuer will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders
of Notes at the close of business on the February 1 and August 1 next preceding the Interest Payment Date, even if such Notes are
canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture
with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest, if any, at the office
or agency of the Issuer maintained for such purpose, or, at the option of the Issuer, payment of interest may be made by check

plus accrued and unpaid interest, if any, to the date of redemption (subject to the rights of Holders on the relevant record date
to receive interest on the relevant Interest Payment Date), provided that:

and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and

 

(ii)         the
redemption occurs within 180 days of the date of the closing of such Equity Offering.

date to receive interest due on the relevant Interest Payment Date.

 

(c)          The
Issuer may redeem all (but not a portion of) the Notes when permitted by, and pursuant to the conditions in, Section 4.15(f) of
the Indenture.

 

(d)          Except

(7)         REPURCHASE
AT THE OPTION OF HOLDER.

 

(a)          If
there is a Change of Control, the Issuer will be required to make an offer (a “Change of Control Offer”) to
each Holder to repurchase all or any part (equal to $1,000 or an integral multiple of $1.00 in excess thereof) of each Holder’s
Notes at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if
any, thereon to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the
relevant Interest Payment Date (the “Change of Control Payment”). Within 30 days following any Change of Control,
the Issuer will mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by
the Indenture.

 

(b)          If
the Issuer or a Restricted Subsidiary of the Issuer consummates any Asset Sales, within five days of each date on which the aggregate
amount of Excess Proceeds exceeds $20.0 million, the Issuer will make an Asset Sale Offer to all Holders of Notes and, if required
by the terms of other Parity Lien Debt, to all holders of such other Parity Lien Debt to purchase, prepay or redeem, on a pro rata
basis, the maximum principal amount of Notes and such other Parity Lien Debt (plus all accrued interest and the amount of all fees
and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess
Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest,
if any, to the date of purchase, prepayment or redemption, subject to the rights of Holders of Notes on the relevant record date
to receive interest due on the relevant Interest Payment Date, and will be payable in cash. If any Excess Proceeds remain after
consummation of an Asset Sale Offer, the Issuer or any Restricted Subsidiary may use those Excess Proceeds for any purpose not
otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other Parity Lien Debt, if applicable, tendered
in such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such other Parity Lien Debt
to be purchased on a pro rata basis (except as provided in Section 4.10 of the Indenture), based on the amounts tendered. Upon
completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. Holders of Definitive Notes that are
the subject of an offer to purchase will receive an Asset Sale Offer from the Issuer prior to any related purchase date and may
elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to
the Notes.

may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuer may require
a Holder to pay any taxes or similar governmental charge permitted by the Indenture. The Issuer needs not exchange or register
the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed
in part. Also, the Issuer needs not exchange or register the transfer of any Notes for a period of 15 days before a selection of

for 60 days after notice to the Issuer by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes
then outstanding to comply with any of its other agreements in the Indenture; (vi) default under certain other agreements relating
to Indebtedness of the Issuer or any of its Restricted Subsidiaries which default is a Payment Default or results in the acceleration
of such Indebtedness prior to its express maturity; (vii) failure by the Issuer or any of its Restricted Subsidiaries to pay certain
final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $15.0 million (to the extent not
covered by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments

in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor,
or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Note Guarantee, except, in each
case, by reason of the release of such Note Guarantee in accordance with the Indenture; and (x) any Note Document or any security
interest created by the Note Documents ceases to be in full force and effect, or the repudiation by the Issuer or any of its Restricted

of bankruptcy or insolvency with respect to the Issuer, any Restricted Subsidiary of the Issuer that is a Significant Subsidiary
or any group of Restricted Subsidiaries of the Issuer that, taken together, would constitute a Significant Subsidiary, all outstanding

to be due and payable immediately. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject
to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time,

conferred on it. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except
a Default or Event of Default relating to the payment of principal, or premium or interest, if any) if it determines that withholding
notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to
the Trustee may, on behalf of all the Holders, rescind an acceleration or waive an existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of Default in the payment of principal of, or premium or
interest, if any, on, the Notes (including in connection with an offer to purchase any Notes). The Issuer is required to deliver
to the Trustee annually an Officers’ Certificate regarding compliance with the Indenture, and the Issuer is required, upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a written statement specifying such Default or Event
of Default.
