to CEDE & Co., or registered assigns, an amount equal to the Redemption Amount (as defined below), in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts,
on the Stated Maturity Date. The “Initial Stated Maturity Date” shall be July 13, 2012. If no Market Disruption Event (as defined below) occurs or is continuing with respect to the Index (as defined below) on the scheduled
Calculation Day (as defined below), the Initial Stated Maturity Date will be the “Stated Maturity Date.” If a Market Disruption Event occurs or is continuing with respect to the Index on the scheduled Calculation Day, the
“Stated Maturity Date” shall be the later of (i) three Business Days (as defined below) after the postponed Calculation Day and (ii) the Initial Stated Maturity Date. This Security shall not bear any interest. 

Any payments on this Security at Maturity will be made against presentation of this Security at the office or agency of the Company
maintained for that purpose in the City of Minneapolis, Minnesota and at any other office or agency maintained by the Company for such purpose. 
 “Face Amount” shall mean, when used with respect to this Security, the amount set forth on the face of this Security as its “Face Amount.” 

 Determination of Redemption Amount 

The “Redemption Amount” of this Security will equal: 

 

	 	•	 	 If the Ending Level is greater than or equal to the Starting Level: the Face Amount plus the Contingent Fixed Return;

  

	 	•	 	 If the Ending Level is less than the Starting Level, but greater than or equal to the Threshold Level: the Face Amount; or

  

	 	•	 	 If the Ending Level is less than the Threshold Level: the Face Amount minus: 

 

													
		 	

	  	Face Amount	  	x	  	  

Starting Level – Ending Level
	    	

	  	
		 	  	  	  	Starting Level	    	  	

 “Index” shall mean the S&P 500® Index. 
 The “Pricing Date” shall mean June 6, 2011. 
 The
“Starting Level” is 1286.17, the Closing Level of the Index on the Pricing Date. 
 The “Closing
Level” of the Index on any Trading Day means the official closing level of the Index as reported by the Index Sponsor on such Trading Day. 
 The “Ending Level” will be the Closing Level of the Index on the Calculation Day. 
 The “Contingent Fixed Return” is 10.25% of the Face Amount of this Security. 
 The “Threshold Level” is 1067.52, which is equal to 83% of the Starting Level. 
 “Index Sponsor” shall mean Standard & Poor’s, a division of the McGraw-Hill Companies, Inc. 
 “Business Day” shall mean a day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions are authorized or required by law or regulation
to close in New York, New York or Minneapolis, Minnesota. 
 A “Trading Day” with respect to the Index means a
day, as determined by the Calculation Agent, on which (i) the Relevant Exchanges (as defined below) with respect to the securities underlying the Index are open for trading for their regular trading sessions and (ii) the exchanges on which
futures or options contracts related to the Index or successor thereto, if applicable, are traded, are open for trading for their respective regular trading sessions. 
 The “Calculation Day” shall be July 6, 2012 or, if such day is not a Trading Day, the next succeeding Trading Day. The Calculation Day is subject to postponement due to the
occurrence of a Market Disruption Event. If a Market Disruption Event occurs or is continuing with respect to the Index on the Calculation Day, such Calculation Day will be postponed to the first

  
 2 

 
succeeding Trading Day on which a Market Disruption Event has not occurred and is not continuing. If such first succeeding Trading Day has not occurred as of the eighth scheduled Trading Day
after the scheduled Calculation Day, that eighth scheduled Trading Day shall be deemed the Calculation Day. If the Calculation Day has been postponed eight scheduled Trading Days after the scheduled Calculation Day and such eighth scheduled Trading
Day is not a Trading Day, or if a Market Disruption Event occurs or is continuing with respect to the Index on such eighth scheduled Trading Day, the Calculation Agent will determine the Closing Level of the Index on such eighth scheduled Trading
Day in accordance with the formula for and method of calculating the Closing Level of the Index last in effect prior to commencement of the Market Disruption Event, using the closing price (or, with respect to any of the relevant securities, if such
date is not a Trading Day or a Market Disruption Event has occurred, its good faith estimate of the closing price that would have prevailed for such securities) on such date of each security most recently included in the Index. See “Market
Disruption Events.” As used herein, “closing price” means, with respect to any security on any date, the last reported sales price regular way on such date or, in case no such reported sale takes place on such date, the average
of the reported closing bid and asked prices regular way on such date, in either case on the primary organized exchange or trading system on which such security is then listed or admitted to trading. 

“Calculation Agent Agreement” shall mean the Calculation Agent Agreement dated as of June 13, 2011 between the
Company and the Calculation Agent, as amended from time to time. 
 “Calculation Agent” shall mean the Person
that has entered into the Calculation Agent Agreement with the Company providing for, among other things, the determination of the Ending Level and the Redemption Amount, which term shall, unless the context otherwise requires, include its
successors under such Calculation Agent Agreement. The initial Calculation Agent shall be Wells Fargo Securities, LLC. Pursuant to the Calculation Agent Agreement, the Company may appoint a different Calculation Agent from time to time after the
initial issuance of this Security without the consent of the Holder of this Security and without notifying the Holder of this Security. 

Discontinuance Of The Index; Alteration Of Method Of Calculation 
 If the Index Sponsor discontinues publication of the Index, and the Index Sponsor or another entity publishes a successor or substitute equity index that the Calculation Agent determines, in its sole
discretion, to be comparable to the Index (a “Successor Equity Index”), then, upon the Calculation Agent’s notification of that determination to the Trustee and the Company, the Calculation Agent will substitute the Successor
Equity Index as calculated by the relevant Index Sponsor or any other entity and calculate the Ending Level as described above. Upon any selection by the Calculation Agent of a Successor Equity Index, the Company will cause notice to be given to the
Holder of this Security. 
 In the event that the Index Sponsor discontinues publication of the Index and the Calculation Agent
does not select a Successor Equity Index, the Calculation Agent will compute a substitute level for the Index in accordance with the procedures last used to calculate the Index before any discontinuance. If a Successor Equity Index is selected or
the Calculation Agent calculates a level as a substitute for the Index, the Successor Equity Index or level will be used as a substitute for the Index for all purposes, including the purpose of determining whether a Market Disruption Event exists.

  
 3 

 If at any time the Index Sponsor makes a material change in the formula for or the method of
calculating the Index, or in any other way materially modifies the Index so that the Index does not, in the opinion of the Calculation Agent, fairly represent the level of the Index had those changes or modifications not been made, then, from and
after that time, the Calculation Agent will, at the close of business in New York, New York, on the date that the Closing Level of the Index is to be calculated, make any adjustments as, in the good faith judgment of the Calculation Agent, may be
necessary in order to arrive at a value of an equity index comparable to the Index as if those changes or modifications had not been made, and calculate the level of the Index with reference to such equity index, as so adjusted. Accordingly, if the
method of calculating the Index is modified so that the level of the Index is a fraction or a multiple of what it would have been if it had not been modified, then the Calculation Agent will adjust the Index in order to arrive at a level of the
Index as if it had not been modified. 
 Market Disruption Events 

A “Market Disruption Event” means, with respect to the Index, any of the following events as determined by the
Calculation Agent in its sole discretion: 
  

	 	(A)	A material suspension or material limitation of trading in the securities which then comprise 20% or more of the level of the Index or any Successor Equity Index has
been imposed by the Relevant Exchanges on which those securities are traded, at any time during the one-hour period preceding the Close of Trading on such day, whether by reason of movements in price exceeding limits permitted by those Relevant
Exchanges or otherwise. 

  

	 	(B)	A material suspension or material limitation of trading has occurred on that day, in each case during the one-hour period preceding the Close of Trading in options or
futures contracts related to the Index or any Successor Equity Index, on the primary exchange or quotation system on which those options or futures contracts are traded, whether by reason of movements in price exceeding levels permitted by the
exchange, the quotation system or otherwise. 

  

	 	(C)	Any event, other than an early closure, that materially disrupts or impairs the ability of market participants in general to effect transactions in, or obtain market
values for, the securities that then comprise 20% or more of the level of the Index or any Successor Equity Index, at any time during the one-hour period that ends at the Close of Trading on that day. 

 

	 	(D)	Any event, other than an early closure, that materially disrupts or impairs the ability of market participants in general to effect transactions in, or obtain market
values for, the futures or options contracts relating to the Index or any Successor Equity Index on the primary exchange or quotation system on which those futures or options contracts are traded, at any time during the one-hour period that ends at
the Close of Trading on that day. 

  
 4 

	 	(E)	The closure of the Relevant Exchanges on which the securities that then comprise 20% or more of the level of the Index or any Successor Equity Index are traded or the
primary exchange or quotation system on which futures or options contracts relating to the Index or any Successor Equity Index are traded prior to its scheduled Close of Trading unless the earlier closing time is announced by the Relevant Exchanges,
the primary exchange or the quotation system, as applicable, at least one hour prior to the earlier of (1) the actual closing time for the regular trading session on the Relevant Exchanges, the primary exchange or the quotation system, as
applicable, and (2) the submission deadline for orders to be entered into the relevant exchanges, the primary exchange or the quotation system, as applicable, for execution at the Close of Trading on that day. 

For purposes of determining whether a Market Disruption Event has occurred: 

 

	 	(1)	the relevant percentage contribution of a security to the level of the Index or any Successor Equity Index will be based on a comparison of (x) the portion of the
level of the Index attributable to that security and (y) the overall level of the Index or Successor Equity Index, in each case immediately before the occurrence of the Market Disruption Event; 

 

	 	(2)	“Close of Trading” means in respect of any Relevant Exchange, primary exchange or quotation system, the scheduled weekday closing time on a day on
which such Relevant Exchange, primary exchange or quotation system is scheduled to be open for trading for its respective regular trading session, without regard to after hours or any other trading outside the regular trading session hours; and

  

	 	(3)	“Relevant Exchange” for any security (or any combination thereof then underlying the Index or any Successor Equity Index) means the primary exchange or
quotation system on which such security is traded, as determined by the Calculation Agent. 

 Calculation Agent

 The Calculation Agent will determine the Redemption Amount and the Ending Level. In addition, the Calculation Agent
will (i) determine if adjustments are required to the Closing Level of the Index under the circumstances described in this Security, (ii) if publication of the Index is discontinued, select a Successor Equity Index or, if no Successor
Equity Index is available, determine the Closing Level of the Index under the circumstances described in this Security, and (iii) determine whether a Market Disruption Event has occurred. 

The Company covenants that, so long as this Security is Outstanding, there shall at all times be a Calculation Agent (which shall be a
broker-dealer, bank or other financial institution) with respect to this Security. 
 All determinations made by the Calculation
Agent with respect to this Security will be at the sole discretion of the Calculation Agent and, in the absence of manifest error, will be conclusive for all purposes and binding on the Company and the Holder of this Security. All percentages and
other amounts resulting from any calculation with respect to this Security will be rounded at the Calculation Agent’s discretion. 

  
 5 

 Tax Considerations 
 The Company agrees, and by acceptance of a beneficial ownership interest in this Security each Holder of this Security will be deemed to have agreed (in the absence of a statutory, regulatory,
administrative or judicial ruling to the contrary), for United States federal income tax purposes to characterize and treat this Security as a pre-paid derivative contract in respect of the Index. 

Redemption and Repayment 
 This Security is not subject to redemption at the option of the Company or repayment at the option of the Holder hereof prior to July 13, 2012. This Security is not entitled to any sinking fund.

 Acceleration 
 If an Event of Default, as defined in the Indenture, with respect to this Security shall occur and be continuing, the Redemption Amount (calculated as set forth in the next sentence) of this Security may
be declared due and payable in the manner and with the effect provided in the Indenture. The amount payable to the Holder hereof upon any acceleration permitted under the Indenture will be equal to the Redemption Amount hereof calculated as provided
herein as though the date of acceleration was the Calculation Day; provided, however, if such date is not a Trading Day or if a Market Disruption Event has occurred or is continuing on that day, the Calculation Day will be postponed as provided
herein. 
  
  

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if set forth at this place. 
 Unless the certificate of authentication hereon has been
executed by the Trustee referred to on the reverse hereof by manual signature or its duly authorized agent under the Indenture referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit under the
Indenture or be valid or obligatory for any purpose.

 WELLS FARGO & COMPANY 
 MEDIUM-TERM NOTE, SERIES K

 Due Nine Months or More From Date of Issue 

Notes Linked to the S&P 500® Index 
 due July 13, 2012

 This Security is one of a duly authorized issue of securities of the Company (herein called the
“Securities”), issued and to be issued in one or more series under an indenture dated as of July 21, 1999, as amended or supplemented from time to time (herein called the “Indenture”), between the Company and
Citibank, N.A., as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is
one of the series of the Securities designated as Medium-Term Notes, Series K, of the Company, which series is limited to an aggregate principal amount or face amount, as applicable, of $25,000,000,000 or the equivalent thereof in one or more
foreign or composite currencies. The amount payable on the Securities of this series may be determined by reference to the performance of one or more equity-, commodity- or currency-based indices, exchange traded funds, securities, commodities,
currencies, statistical measures of economic or financial performance, or a basket comprised of two or more of the foregoing, or any other market measure or may bear interest at a fixed rate or a floating rate. The Securities of this series may
mature at different times, be redeemable at different times or not at all, be repayable at the option of the Holder at different times or not at all and be denominated in different currencies. 

Article Sixteen of the Indenture shall not apply to this Security. 

The Securities are issuable only in registered form without coupons and will be either (a) book-entry securities represented by one
or more Global Securities recorded in the book-entry system maintained by the Depositary or (b) certificated securities issued to and registered in the names of, the beneficial owners or their nominees. 

The Company agrees, to the extent permitted by law, not to voluntarily claim the benefits of any laws concerning usurious rates of
interest against a Holder of this Security. 
 Modification and Waivers 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the
Securities at the 

  
 8 

 
time Outstanding of all series to be affected, acting together as a class. The Indenture also contains provisions permitting the Holders of a majority in principal amount of the Securities of all
series at the time Outstanding affected by certain provisions of the Indenture, acting together as a class, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with those provisions of the Indenture. Certain
past defaults under the Indenture and their consequences may be waived under the Indenture by the Holders of a majority in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such
series. Solely for the purpose of determining whether any consent, waiver, notice or other action or Act to be taken or given by the Holders of Securities pursuant to the Indenture has been given or taken by the Holders of Outstanding Securities in
the requisite aggregate principal amount, the principal amount of this Security will be deemed to be equal to the amount set forth on the face hereof as the “Face Amount” hereof. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Security. 
 Defeasance

indebtedness on this Security and (b) certain restrictive covenants and certain Events of Default, upon compliance by the Company with certain conditions set forth therein, shall not apply to this Security. The remaining provisions of
Section 401 of the Indenture shall apply to this Security.

integral multiple of $1,000.

terms as this Security, in authorized denominations for an equal aggregate Face Amount will be issued to the transferee in exchange herefor, as provided in the Indenture and subject to the limitations provided therein and to the limitations
described below, without charge except for any tax or other governmental charge imposed in connection therewith. 
 This
Security is exchangeable for definitive Securities in registered form only if (x) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for this Security or if at any time the Depositary ceases to be a
clearing agency registered under the Securities Exchange Act of 1934, as amended, and a successor depositary is not appointed within 90 days after the Company receives such notice or becomes aware of such ineligibility, (y) the Company in
its sole discretion determines that this Security shall be exchangeable for definitive Securities in registered form and notifies the Trustee thereof or (z) an Event of Default with respect to the Securities represented hereby has occurred and
is continuing. If this Security is exchangeable pursuant to the preceding sentence, it shall be exchangeable for definitive Securities in registered form, having the same date of issuance, Stated Maturity Date and other terms and of authorized
denominations aggregating a like amount. 

  
 9

Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor of the Depositary or a nominee of such successor. Except as provided above, owners of
beneficial interests in this Global Security will not be entitled to receive physical delivery of Securities in definitive form and will not be considered the Holders hereof for any purpose under the Indenture. 

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the

Amount at the times, place and rate, and in the coin or currency, herein prescribed, except as otherwise provided in this Security. 
 No

whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issuance hereof, expressly
waived and released.

 The Issuer, the Guarantors and the

 ARTICLE 1 
 DEFINITIONS AND INCORPORATION 

BY REFERENCE 
 Section 1.01
Definitions. 
 “144A Global Note” means the Global Note substantially in the form of Exhibit A hereto
bearing the Global Note Legend and the Private Placement Legend and deposited with or on behalf of and registered in the name of the Depositary or its nominee that will be issued in a denomination equal to the outstanding principal amount of the
Notes sold in reliance on Rule 144A. 
 “Acquired Debt” means, with respect to any specified Person:

 (1) Indebtedness of any other Person existing at the time such other Person is merged with or into or became a
Subsidiary of such specified Person (regardless of the form of the applicable transaction by which such Person became a Subsidiary) or expressly assumed in connection with the acquisition of assets from any such Person, whether or not such
Indebtedness is incurred in connection with, or in contemplation of, such other Person merging with or into, or becoming a Restricted Subsidiary of, such specified Person or of such Indebtedness being incurred in connection with the acquisition of
assets; and 
 (2) Indebtedness secured by a Lien encumbering any asset acquired by such specified Person.

 Acquired Debt will be deemed to be incurred on the date the acquired Person becomes a Subsidiary or the date of the related
acquisition of assets from such Person. 
 “Additional Interest” means all additional interest then owing on
the Notes pursuant to the Registration Rights Agreement. 
 “Additional Notes” means Notes (other than the
Initial Notes) issued after the Issue Date under this Indenture in accordance with Sections 2.01, 2.02 and 4.14 hereof, as part of the same class as the Initial Notes. 
 “Affiliate” of any specified Person means any other Person directly or indirectly controlling or controlled by or under direct or indirect common control with such specified Person. For
purposes of this definition, “control,” as used with respect to any Person, means the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of such Person, whether through the
ownership of voting securities, by agreement or otherwise; provided that beneficial ownership of 10% or more of the Voting Stock of a Person will be deemed to be control. For purposes of this definition, the terms “controlling,”
“controlled by” and “under common control with” have correlative meanings. 
 “Agent” means
any Registrar, co-registrar, Paying Agent or additional paying agent. 

  
 1 

 “Applicable Premium” means, with respect to any Note on any redemption
date, the greater of: 
 (1) 1.0% of the principal amount of the Note; or 

(2) the excess of: 
 (a) the present value at such redemption date of (i) the redemption price of the Note at June 15, 2015, (such redemption price being set forth in Section 3.07 hereof) plus (ii) all
required interest payments due on the Note through June 15, 2015 (excluding accrued but unpaid interest to the redemption date), computed using a discount rate equal to the Treasury Rate as of such redemption date plus 50 basis points; over

 (b) the principal amount of the Note. 
 Calculation of the Applicable Premium shall be the sole responsibility of the Issuer and the Trustee shall have no obligation to calculate or verify any calculation of the Applicable Premium. 

“Applicable Procedures” means, with respect to any transfer or exchange of or for beneficial interests in any Global
Note, the rules and procedures of the Depositary, Euroclear and Clearstream that apply to such transfer or exchange. 

“Asset Sale” means: 
 (1) the sale, lease, conveyance or other voluntary disposition of any assets or rights; provided that the sale, lease, conveyance or other disposition of all or substantially all of the assets of
the Issuer and its Restricted Subsidiaries taken as a whole will be governed by Section 4.10 hereof, and/or Section 5.01 hereof, and not by Section 4.11 hereof; and 

(2) the issuance or sale of Equity Interests in the Issuer’s Restricted Subsidiaries or the sale of Equity Interests
in any of its Subsidiaries; provided that, for the avoidance of doubt, the sale of Equity Interests of the Issuer will be governed by Section 4.10 and Article 5 of this Indenture and not by Section 4.11 of this Indenture.

 Notwithstanding the preceding, none of the following items will be deemed to be an Asset Sale: 

(1) any single transaction or a series of related transactions that involves assets having a Fair Market Value of less

Section 4.13 or the making or disposition of a Permitted Investment; and 
 (7) any trade or exchange by the
Issuer or any Restricted Subsidiary of the Issuer of equipment or other assets for equipment or other assets owned or held by another Person, provided that the Fair Market Value of the assets traded or exchanged by the Issuer or such Restricted
Subsidiary (together with any cash or Cash Equivalents) is reasonably equivalent to the Fair Market Value of the assets (together with any cash or Cash Equivalents) to be received by the Issuer or such Restricted Subsidiary. 

“Bankruptcy Law” means Title 11, U.S. Code or any similar federal or state law for the relief of debtors. 

“Beneficial Owner” has the meaning assigned to such term in Rule 13d-3 and Rule 13d-5 under the Exchange Act, except

“person” has the right to acquire by conversion or exercise of other securities, whether such right is currently exercisable or is exercisable only after the passage of time. The terms “Beneficially Owns” and “Beneficially
Owned” have a corresponding meaning.

 “Cash Equivalents” means: 

(1) United States dollars or the U.S. Dollar Equivalent; 

(2) securities issued or directly and fully guaranteed or insured by the United States government or any agency or

clauses (1) through (7) of this definition.

the income or profits of, and the depreciation, amortization and other non-cash expenses of, a Restricted Subsidiary of the Issuer will be added to Consolidated Net Income to compute Consolidated Cash Flow of the Issuer, only to the extent that a
corresponding amount would be permitted at the date of determination to be dividended to the Issuer by such Restricted Subsidiary without prior governmental approval (that has not been obtained), and without direct or indirect restriction pursuant

method of accounting will be included only to the extent of the amount of dividends or similar distributions paid in cash to the specified Person or a Restricted Subsidiary of the Person; 

(2) the Net Income of any Restricted Subsidiary will be excluded to the extent that the declaration or payment of
dividends or similar distributions by that Restricted Subsidiary of that Net Income is not at the date of determination permitted without any prior governmental approval (that has not been obtained) or, directly or indirectly, by operation of the
terms of its charter or any agreement, instrument, judgment, decree, order, statute, rule or governmental regulation applicable to that Restricted Subsidiary or its stockholders; 

(3) unrealized losses and gains under derivative instruments included in the determination of Consolidated Net Income,

alternative minimum tax carryforwards, that arise in any period will be available to offset taxable income payable in later years (regardless of any change in status as a Flow Through Entity). Notwithstanding anything to the contrary, for purposes

 (a) General. The Notes and the Trustee’s certificate of authentication will be
substantially in the form of Exhibit A hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. The Notes shall be issued in minimum
denominations of $2,000 and integral multiples of $1,000 in excess thereof. 
 The Issuer may issue Additional Notes from time
to time after the Issue Date provided such issuance and incurrence would then comply with Section 4.14. The Initial Notes, the Additional Notes and the Exchange Notes shall be treated as a single class for all purposes under this Indenture, and
unless the context otherwise requires, all references to the “Notes” shall include the Initial Notes, any Additional Notes and any Exchange Notes. 
 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 shall govern and be
controlling. 
 (b) Global Notes. Notes issued in global form will be substantially in the form of Exhibit A hereto
(including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note

of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof. 
 (c)
Temporary Global Notes. Notes offered and sold in reliance on Regulation S will be issued initially in the form of the Regulation S Temporary Global Note, which will be deposited on behalf of the purchasers of the Notes represented thereby

authenticated by the Trustee as hereinafter provided. 

  
 24 

 Following the termination of the Restricted Period, beneficial interests in the Regulation S
Temporary Global Note will be exchanged for beneficial interests in the Regulation S Permanent Global Note pursuant to the Applicable Procedures. Simultaneously with the Trustee’s authentication of the Regulation S Permanent Global Note, the
Trustee will cancel the Regulation S Temporary Global Note. The aggregate principal amount of the Regulation S Temporary Global Note and the Regulation S Permanent Global Note may from time to time be increased or decreased by adjustments made on
the records of the Trustee and the Depositary or its nominee, as the case may be, in connection with transfers of interest as hereinafter provided. 
 (d) Euroclear and Clearstream Procedures Applicable. The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear”
and the “General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream will be applicable to transfers of beneficial interests in the Regulation S Temporary Global Note and the Regulation S Permanent
Global Note that are held by Participants through Euroclear or Clearstream. 
 Section 2.02 Execution and Authentication.

 At least one Officer of the Issuer must sign the Notes for the Issuer by manual or facsimile 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 so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the

for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Issuer may appoint one or more co-registrars and one or more additional paying agents. The term
“Registrar” includes any co-registrar and the term “Paying Agent” includes any additional 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 entity as Registrar or Paying Agent, the Trustee shall act as such. The Trustee will initially act as Paying Agent and
Registrar. The Issuer or any of its Subsidiaries may act as Paying Agent or Registrar, so long as no Event of Default is continuing. 

  
 25 

 The Issuer initially appoints The Depository Trust Company (“DTC”) to act
as Depositary with respect to the Global Notes. 
 The Issuer initially appoints the Trustee to act as Custodian with respect to
the Global Notes.

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, premium, if any, or interest 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. 

Section 2.05 Holder Lists. 
 The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA
§ 312(a). If the Trustee is not the Registrar, the Issuer will furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as
of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Issuer shall otherwise comply with TIA § 312(a). 
 Section 2.06 Transfer and Exchange. 
 (a) Transfer and Exchange of
Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such
nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by the Issuer for Definitive Notes if: 
 (1) the Issuer delivers to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange
Act and, in either case, a successor Depositary is not appointed by the Issuer within 90 days after the date of such notice from the Depositary; 

(2) the Issuer in its sole discretion determines that the Global Notes (in whole but not in part)
should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee; provided that in no event shall the Regulation S Temporary Global Note be exchanged by the Issuer for Definitive Notes prior to (A) the
expiration of the Restricted Period and (B) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act; or 
 (3) there has occurred and is continuing a Default or Event of Default with respect to the Notes and the Registrar has received a request from the Depositary to issue Definitive Notes. 

  
 26 

 Upon the occurrence of either of the preceding events in (1), (2) or (3) above, Definitive Notes
shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered in exchange for, or
in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for
another Note other than as provided in this Section 2.06(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b), (c) or (f) hereof. 

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the

of a U.S. Person (other than an Initial Purchaser). Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders
or instructions shall be required to be delivered to the Registrar to effect the transfers set forth in this Section 2.06(b)(1). 
 (2) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are not subject to Section 2.06(b)(1)

and the Notes or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to Section 2.06(h) hereof.

3.06, 3.09, 4.10, 4.11 and 9.05 hereof). 
 (3) The Registrar will not be required to register the transfer of or

 If the Paying Agent (other than the Issuer, a Subsidiary or an Affiliate of any thereof) holds, 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.

 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 a Responsible Officer of the Trustee knows are so owned will be so disregarded. 

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 considers appropriate for temporary Notes. Without unreasonable delay, the Issuer will prepare and the Trustee will authenticate (upon receipt of an
Authentication Order) 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 requirement of the Exchange Act and the Trustee in accordance with the Trustee’s customary procedures). Certification of the cancellation of all canceled Notes will be delivered to the Issuer upon the
Issuer’s written request. 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; Additional Interest. 
 The Issuer will
pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal, premium, if any, and interest (without regard to any applicable grace period) from time to time on demand at the rate equal to
2% per annum in excess of the then applicable interest rate on the Notes to the extent lawful to the Persons who are Holders on a subsequent special record date, in each case at the rate provided as set forth in the Notes and consistent with
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 mail or cause to be sent to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 

The Issuer will pay Additional Interest, if any, to Holders of Notes pursuant to the Registration Rights Agreement. 

All reference to “interest” in this Indenture and the Notes mean the initial interest rate borne by the Notes and any increases
in that rate due to defaulted interest or Additional Interest, unless this Indenture states otherwise.

Owners.

integral multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except as
provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase. 
 Section 3.03 Notice of Redemption. 
 Subject to the provisions of
Section 3.09 hereof, 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 or sent electronically, a notice of redemption to each Holder whose Notes are to be

pursuant to Articles 8 or 10 hereof. 
 The notice will identify the Notes to be redeemed and will state: 

(1) the applicable Redemption Date; 

(2) the applicable Redemption Price; 

(3) the CUSIP number(s) of the Notes; 

(4) If the Notes are being redeemed in part:

securities exchange, in compliance with the requirements of such exchange on which the Notes are listed (and such listing is known to the Trustee); or (ii) on a pro rata basis, by lot or by such other method as the Trustee considers fair
and appropriate, unless otherwise required by law or applicable stock exchange requirements; and in either case, not in parts of $2,000 or less; and the portion of the principal amount of such Notes to be redeemed and that, after the redemption date

Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and 
 (8) that
no representation is made as to the correctness or accuracy of the CUSIP 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 name and at the Issuer’s expense; provided, however, that the Issuer has delivered to the
Trustee, at least 45 days prior to the redemption date, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information (or a shorter period as agreed to by the Trustee) to be stated in such notice as
provided in this Section 3.03. 
 Section 3.04 Effect of Notice of Redemption. 

Once notice of redemption is sent in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and
payable on the redemption date at the redemption price. A notice of redemption may not be conditional. 
 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 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 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 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
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 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 and in Section 4.01 hereof.

Trustee is the Paying Agent) 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; 

  
 44 

 (8) that, if the aggregate principal amount of Notes and other pari
passu Indebtedness surrendered by holders thereof exceeds the Offer Amount, the Trustee will select the Notes and the Issuer or other applicable agent will select for such other pari passu Indebtedness to be purchased on a pro rata
basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Issuer so that only Notes in minimum amounts of $2,000 and integral multiples of $1,000
in excess thereof, will be purchased); and

issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer).

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 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 delivery of an Authentication Order, 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 or as soon as practicable after the Purchase Date. 

Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to
the provisions of Sections 3.01 through 3.06 hereof. 
 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 pursuant to an applicable Offer to Purchase. To the extent that the provisions
of any securities laws or regulations conflict with the provisions of this Section 3.09 or Section 4.11 of this Indenture, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached

Permitted Business; 
 provided that if the Issuer or such Restricted Subsidiary enters into a binding agreement to acquire such assets
or capital stock or make such capital expenditures within such 365-day period, but the consummation of the transactions under such agreement has not occurred within such 365-day period, and the agreement has not been terminated, then either
(a) the 365-day period will be extended an additional 180 days to permit such consummation; or (b) if such consummation does not occur, or such agreement is terminated within such additional 180-day period, then the Issuer may apply, or
cause such Restricted Subsidiary to apply, within 60 days after the earlier of the end of such 180-day period or the effective date of such termination, such Net Proceeds as provided in clauses (1), (2), (3) and (4) of this
Section 4.11(b). 
 Pending the final application of any Net Proceeds, the Issuer or the applicable Restricted Subsidiary,
as the case may be, may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture. 
 (c) Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.11(b) hereof will constitute “Excess Proceeds.” When the aggregate amount of Excess
Proceeds exceeds $10.0 million, the Issuer will, within fifteen (15) days thereof, make an Offer to Purchase Notes pursuant to this Section 4.11 and Section 3.09 (an “Asset Sale Offer”) to all Holders of Notes and all
holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum
principal amount of Notes and such other pari passu Indebtedness that may be purchased 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 and
Additional Interest, if any, to the date of purchase, and will be payable in cash; provided, however, that if the Issuer is required to apply such Excess Proceeds to repurchase, or to offer to repurchase, any pari passu Indebtedness,
the Issuer shall only be required to offer to repurchase the maximum principal amount of Notes that may be purchased out of the amount of such Excess Proceeds multiplied by a fraction, the numerator of which is the aggregate principal amount of
Notes outstanding and the denominator of which is the aggregate principal amount of Notes outstanding plus the aggregate principal amount of pari passu Indebtedness outstanding. 

If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Issuer may use those Excess Proceeds for any purpose not
otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and the Issuer
or such other agent will select for such other pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 

  
 50 

 (d) The Issuer will not and will not permit its Restricted Subsidiaries to, enter into or
suffer to exist any agreement (other than any agreement governing Credit Facilities for Indebtedness permitted to be incurred pursuant to clause (1) of Section 4.14(b)) that would place any restriction of any kind (other than pursuant to
law or regulation) on the ability of the Issuer to make an Asset Sale Offer. 
 (e) 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 pursuant to an Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with this Section 4.11, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.11 by
virtue of such compliance. 
 Section 4.12 [Intentionally Omitted] 
 Section 4.13 Restricted Payments. 
 (a) The Issuer shall not and shall
not permit any of its Restricted Subsidiaries to, directly or indirectly: 
 (1) declare or pay any dividend or
make any other payment or distribution on account of the Issuer’s Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Issuer) or to the direct or indirect holders of the
Issuer’s Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Issuer; 

(2) purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any
merger or consolidation involving the Issuer) any Equity Interests of the Issuer; 
 (3) make any payment on or
with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness of the Issuer or any Guarantor that is contractually subordinated to the Notes or to any Note Guarantee (excluding any intercompany Indebtedness
between or among the Issuer and any of its Restricted Subsidiaries or between or among Restricted Subsidiaries), except a payment of interest or principal at the Stated Maturity thereof; or 

(4) make any Restricted Investment 
 (all such payments and other actions set forth in these clauses (1) through (4) above being collectively referred to as “Restricted Payments”), 

unless, at the time of and after giving effect to such Restricted Payment: 

(1) no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted
Payment; 

  
 51 

 (2) the Issuer would, at the time of such Restricted Payment and after
giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
test set forth in Section 4.14(a) hereof; and 
 (3) such Restricted Payment, together with the aggregate
amount of all other Restricted Payments made by the Issuer and its Restricted Subsidiaries after the Issue Date (excluding Restricted Payments permitted by clauses (2) through (10) of paragraph (b) of this Section 4.13), is less
than the sum, without duplication, of: 
 (A) 50% of the cumulative Consolidated Net Income of the Issuer for the
period (taken as one accounting period) from April 1, 2011 to the end of the Issuer’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated
Net Income for such period is a deficit, less 100% of such deficit), plus 
 (B) subject to
Section 4.14(b)(2), 100% of the aggregate net cash proceeds received by the Issuer since the Issue Date as a contribution to its common equity capital or from the issue or sale of Equity Interests of the Issuer (other than Disqualified Stock)
or from the issue or sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of the Issuer that have been converted into or exchanged for such Equity Interests (other than any such Equity Interests,
Disqualified Stock or convertible or exchangeable debt securities sold to a Subsidiary of the Issuer); plus 
 (C) to the extent that any Restricted Investment that was made after the Issue Date is sold for cash or otherwise liquidated or repaid for cash, the lesser of (i) the cash return of capital with
respect to such Restricted Investment (less the cost of disposition, if any) and (ii) the initial amount of such Restricted Investment; plus 
 (D) to the extent that any Unrestricted Subsidiary of the Issuer designated as such after the Issue Date is redesignated as a Restricted Subsidiary after the Issue Date, the lesser of (i) the Fair
Market Value of the Issuer’s Investment in such Subsidiary, as the case may be, as of the date of such redesignation or (ii) such Fair Market Value as of the date on which such Subsidiary was originally designated as an Unrestricted
Subsidiary after the Issue Date; plus 
 (E) 50% of any dividends received by the Issuer or any of its Restricted
Subsidiaries, as the case may be, after the Issue Date from an Unrestricted Subsidiary of the Issuer, to the extent that such dividends were not otherwise included in the Consolidated Net Income of the Issuer for such period. 

(b) The preceding provisions will not prohibit: 
 (1) the payment of any dividend or distribution or the consummation of any irrevocable redemption within 60 days after the date of declaration of the dividend or distribution or giving of the redemption
notice, as the case may be, if at the date of declaration or notice, the dividend, distribution or redemption payment would have complied with the provisions of this Indenture; 

(2) the making of any Restricted Payment in exchange for, or out of the net cash proceeds of the substantially concurrent
sale (other than to a Subsidiary of the Issuer) of, Equity Interests of the Issuer (other than Disqualified Stock) or from the substantially concurrent contribution of common equity capital to the Issuer; provided that the amount of any such
net cash proceeds that are utilized for any such Restricted Payment will be excluded from subclause (B) of the second clause (3) of paragraph (a) of this Section 4.13; 

  
 52 

 (3) the repurchase, redemption, defeasance or other acquisition or
retirement for value of Indebtedness of the Issuer or any Guarantor that is contractually subordinated to the Notes or to any Note Guarantee with the net cash proceeds from a substantially concurrent incurrence of, or in exchange for, Permitted
Refinancing Indebtedness; 
 (4) so long as no Default has occurred or is continuing or would be caused thereby,
the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Issuer or any of its Restricted Subsidiaries held by any current or former officer, director or employee of the Issuer or any of its Restricted
Subsidiaries pursuant to an agreement approved by the Board of Directors of the Issuer; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed $1,000,000 in any
twelve-month period; 
 (5) the repurchase of Equity Interests deemed to occur upon the exercise of stock options
to the extent such Equity Interests represent a portion of the exercise price of those stock options or the repurchase of stock appreciation rights by way of cashless exercise or in connection with the satisfaction of withholding tax obligations;

 (6) so long as no Default has occurred or is continuing or would be caused thereby, the declaration and
payment of regularly scheduled or accrued dividends to holders of any class or series of Disqualified Stock of the Issuer or any of its Restricted Subsidiaries issued after the Issue Date in accordance with the Fixed Charge Coverage Ratio test set
forth in Section 4.14(a) hereof; 
 (7) in connection with an acquisition by the Issuer or any of its
Restricted Subsidiaries, the return to the Issuer or any of its Restricted Subsidiaries of Equity Interests of the Issuer or such Restricted Subsidiary constituting a portion of the purchase price consideration in settlement of indemnification
claims; 
 (8) the purchase by the Issuer of fractional shares of Equity Interests arising out of stock
dividends, splits or combinations or business combinations; 
 (9) Permitted Tax Distributions; 

(10) the payment of any dividends on the Issuer’s Series B Preferred Shares (or similar class of equity) pursuant to
the certificate of designation governing such class of securities up to a maximum of $260,000 per quarter in cash, which amount represents the maximum payable quarterly in cash as dividends on such class of securities based on the Series B Preferred
Shares presently outstanding and additional such shares that may be issued under the provisions of the certificate of designations governing the Series B Preferred Shares that permit payment of dividends in kind; and 

(11) so long as no Default has occurred or is continuing or would be caused thereby, other Restricted Payments in an
aggregate amount not to exceed $10.0 million since the Issue Date. 

  
 53 

 (c) The amount of all Restricted Payments (other than cash) will be the Fair Market Value on
the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Issuer or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair Market Value of any assets or
securities that are required to be valued by this covenant will be determined by the Board of Directors of the Issuer whose resolution with respect thereto will be delivered to the Trustee. Such Board of Directors’ determination must be based
upon an opinion or appraisal issued by a reputable accounting, appraisal or investment banking firm if the Fair Market Value exceeds $5.0 million. 
 Section 4.14 Incurrence of Indebtedness and Issuance of Preferred Stock. 
 (a) The Issuer will not and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Issuer will not issue any Disqualified Stock, and will not permit any of its Restricted Subsidiaries to issue any
shares of preferred 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 2.0 to 1, in each case, 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. 
 (b) The provisions of Section 4.14(a) hereof will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”): 

(1) the incurrence by the Issuer and any Guarantor of additional Indebtedness and letters of credit under any Credit
Facility (A) in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum stated amount thereof of the Issuer and its Restricted
Subsidiaries thereunder) not to exceed the greater of (A) $75.0 million and (B) 18% of the Issuer’s Consolidated Tangible Assets determined as of the end of the Issuer’s most recently completed fiscal quarter for which internal
financial statements are available, less the aggregate amount of all Net Proceeds of Asset Sales applied by the Issuer or any of its Restricted Subsidiaries since the Issue Date to repay any term Indebtedness under a Credit Facility or to
repay any revolving credit Indebtedness under a Credit Facility and in each case, effect a corresponding commitment reduction thereunder pursuant to Section 4.11 hereof; 

(2) (A) the incurrence by the Issuer and its Restricted Subsidiaries of Existing Indebtedness and (B) encumbrances or
restrictions existing under agreements existing on the Issue Date as in effect on that date; 
 (3) the
incurrence by the Issuer and the Guarantors of Indebtedness represented by the Notes and the related Note Guarantees to be issued on the Issue Date and the Exchange Notes and the related Note Guarantees to be issued pursuant to the Registration
Rights Agreement; 
 (4) the incurrence by the Issuer or any of its Restricted Subsidiaries of Indebtedness
represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of
property, plant or equipment used in the business of the Issuer or any of its Restricted Subsidiaries, as the case may be, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance,
replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed $20.0 million at any time outstanding; 

  
 54 

 (5) the incurrence by the Issuer or any of its Restricted Subsidiaries of
Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be
incurred under Section 4.14(a) hereof or clauses (2), (3), (4), (5) or (12) of this Section 4.14(b); 
 (6) the incurrence by the Issuer or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Issuer and any of its Restricted Subsidiaries or between or among Restricted
Subsidiaries; provided, however, that: 
 (A) if the Issuer or any Guarantor is the obligor on such
Indebtedness and the payee is not the Issuer or a Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes and the Note Guarantees; and 

(B) any (i) subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a
Person other than the Issuer or any of its Restricted Subsidiaries, or (ii) sale or other transfer of any such Indebtedness to a Person that is not any of the Issuer or any of its Restricted Subsidiaries, will be deemed, in each case, to
constitute an incurrence of such Indebtedness by the Issuer or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); 
 (7) the issuance by the Issuer’s Restricted Subsidiaries to the Issuer or to any of its Restricted Subsidiaries of shares of preferred stock; provided, however, that any (A) subsequent
issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than the Issuer or such Restricted Subsidiary, or (B) sale or other transfer of any such preferred stock to a Person that is not the
Issuer or such Restricted Subsidiary, will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that was not permitted by this clause (7); 

(8) the incurrence by the Issuer or any of its Restricted Subsidiaries of Hedging Obligations in the ordinary course of
business; 
 (9) the guarantee by the Issuer or any of the Guarantors of Indebtedness of the Issuer or any of its
Restricted Subsidiaries, as the case may be, that was permitted to be incurred by another provision of this Section 4.14; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the
Guarantee shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed; 
 (10) the incurrence by the Issuer or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims, self-insurance obligations, bankers’ acceptances, bids,
performance and surety bonds, including Guarantees or obligations of the Issuer or such Restricted Subsidiary, as the case may be, with respect to letters of credit supporting such bid, performance or surety obligations (in each case other than for
an obligation for money borrowed) or other forms of security or credit enhancement supporting performance obligations under service contracts, in each case, in the ordinary course of business; 

  
 55 

 (11) the incurrence by the Issuer or any of its Restricted Subsidiaries of
Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days; and

 (12) the incurrence by the Issuer or any of its Restricted Subsidiaries of additional Indebtedness in an
aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to extend, renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to
this clause (12), not to exceed $15.0 million at any one time outstanding after giving pro forma effect to such incurrence and the application of the proceeds therefrom. 
 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 and 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 solely by virtue of being unsecured or by virtue of being secured on a first or junior Lien basis. 

For purposes of determining compliance with this Section 4.14, in the event that an item of proposed Indebtedness meets the criteria
of more than one of the categories of Permitted Debt set forth in clauses (1) through (12) of Section 4.14(b), or is entitled to be incurred pursuant to Section 4.14(a), the Issuer will be permitted to classify such item of
Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.14, and such item of Indebtedness will be treated as having been incurred pursuant to
such category. Indebtedness under Credit Facilities outstanding on the Issue Date 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. The accrual of interest, the accretion or amortization of original issue discount, if applicable, the payment of interest on any Indebtedness 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 Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an
incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.14; provided, in each such case, that the amount of any such accrual, accretion or payment is included in Fixed Charges of the Issuer as
accrued. Notwithstanding any other provision of this Section 4.14, the maximum amount of Indebtedness that the Issuer or any Restricted Subsidiary may incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of
fluctuations in exchange rates or currency values. 
 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 

  
 56 

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

Section 4.15 [Intentionally Omitted] 
 Section 4.16 Liens. 
 The Issuer will not and will not permit any of
its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien of any kind on any asset now owned or hereafter acquired, except Permitted Liens. 
 Section 4.17 Dividend and Other Payment Restrictions Affecting Subsidiaries. 
 The Issuer will not and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the
ability of any Restricted Subsidiary to: 
 (1) pay dividends or make any other distributions on its Capital
Stock to the Issuer or any of its Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or pay any Indebtedness owed to the Issuer or any of its Restricted Subsidiaries; 

(2) make loans or advances to the Issuer or any of its Restricted Subsidiaries; or 

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

 However, the preceding restrictions will not apply to encumbrances or restrictions existing under or by reason of:

 (1) agreements governing Existing Indebtedness and any Credit Facilities as in effect on the Issue Date or
permitted by Section 4.14(b)(1) and any amendments, restatements, modifications, renewals, supplements, extensions, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements, modifications,
renewals, supplements, extensions, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the Issue
Date; 
 (2) this Indenture, the Notes and the Note Guarantees; 

(3) applicable law, rule, regulation or order; 

(4) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Issuer or any of its Restricted
Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred or issued 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 that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture
to be incurred; 

  
 57 

 (5) customary non-assignment provisions in leases, contracts and licenses
entered into in the ordinary course of business, including by reason of customary provisions restricting the transfer of copyrighted or patented materials consistent with industry practice; 

(6) purchase money obligations for property acquired in the ordinary course of business and Capital Lease Obligations that
impose restrictions on the property purchased or leased of the nature set forth in clause (3) of the preceding paragraph; 
 (7) any agreement for the sale or other disposition of a Restricted Subsidiary or assets that restricts distributions by that Restricted Subsidiary pending the sale or other disposition; 

(8) 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; 

(9) Liens permitted to be incurred under the provisions of Section 4.16 that limit the right of the debtor to dispose
of the assets subject to such Liens; 
 (10) provisions limiting the disposition or distribution of assets or
property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements entered into with the approval of the Board of Directors of the Issuer which limitation is applicable only to
the assets that are the subject of such agreements; 
 (11) restrictions on cash or other deposits or net worth
imposed by customers under contracts entered into in the ordinary course of business; and 
 (12) any instrument
governing Indebtedness of a Foreign Subsidiary; provided that such Indebtedness was not prohibited by the terms of this Indenture. 

Section 4.18 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: 
 (1) the Affiliate Transaction is on terms that are no less favorable to the Issuer or the relevant
Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Issuer or such Restricted Subsidiary, as the case may be, with an unrelated Person or, if there is no such comparable transaction, on terms that are
fair and reasonable to the Issuer or such Restricted Subsidiary and reflect an arms’-length negotiation as determined by the Independent Directors; 
 (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 $500,000, whether or not subject to the following clause (2)(B) of this Section 4.18, a resolution of the Board of

  
 58 

 
Directors of the Issuer set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with this covenant and that such Affiliate Transaction has been approved by
a majority of the disinterested members of such Board of Directors who are Independent Directors; and 
 (B) with
respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $2.5 million, an opinion as to the fairness to the Issuer or such Restricted Subsidiary, as the case may be, of such
Affiliate Transaction from a financial point of view issued by a reputable accounting, appraisal or investment banking firm. 

(b) The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of
Section 4.18(a): 
 (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; and between or among 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 directors’ fees to Persons who serve on the Board of Directors of the Issuer; 
 (5) any issuance of Equity Interests (other than Disqualified Stock) of the Issuer to Affiliates of the Issuer; 
 (6) Restricted Payments that do not violate the provisions of Section 4.13 hereof; 
 (7) loans or advances to employees in the ordinary course of business not to exceed $1,000,000 in the aggregate at any one time outstanding; 

(8) registration rights or similar agreements with officers, directors or significant shareholders of the Issuer, provided
that any such registration rights do not materially interfere with or impede the rights granted to Holders under the Registration Rights Agreement; 
 (9) Permitted Tax Distributions; and 
 (10) Permitted Affiliate
Leases. 
 Section 4.19 Business Activities. 
 The Issuer will not, and will not permit any of its Restricted Subsidiaries to, engage in any business other than Permitted Businesses, except to such extent as would not be material to the Issuer and its
Restricted Subsidiaries taken as a whole. 

  
 59 

 Section 4.20 Additional Note Guarantees. 

If the Issuer or any of its Restricted Subsidiaries acquires or creates another Domestic Subsidiary after the Issue Date that is not
declared by the Board of Directors of the Issuer to be an Unrestricted Subsidiary, then the Issuer will (1) cause that newly acquired or created Domestic Subsidiary to (a) execute a supplemental indenture pursuant to which it becomes a
Guarantor and (b) execute an amendment to the Registration Rights Agreement pursuant to which it becomes subject to the obligations of a Guarantor thereunder, and (2) deliver an Opinion of Counsel and Officers’ Certificate, in each
case within 10 business days of the date on which such Domestic Subsidiary was acquired or created; provided that any Domestic Subsidiary that constitutes an Immaterial Subsidiary need not become a Guarantor until such time as it ceases to be
an Immaterial Subsidiary. 
 Section 4.21 Designation of Restricted and Unrestricted Subsidiaries. 

(a) The Board of Directors of the Issuer may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation
would not cause a Default. If a Restricted Subsidiary 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
Unrestricted will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 4.13(a) hereof or 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.” As
of the Issue Date, all Subsidiaries of the Issuer will be Restricted Subsidiaries. 
 (b) 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 and will be deemed as of the date of such failure to be a Restricted Subsidiary for purposes of this
Indenture. In that event, any Indebtedness of such Subsidiary will be deemed to be incurred by such 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 4.14, the Issuer will be in Default of such covenant. 
 (c) 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 4.14 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the
four-quarter reference period; and (2) no Default or Event of Default would be in existence following such designation. 

(d) Any change in the designation of a Subsidiary of the Issuer as an Unrestricted Subsidiary or as a Restricted Subsidiary, as the case
may be, will be evidenced by the Issuer to the Trustee by filing with the Trustee a certified copy of a resolution of its Board of Directors giving effect to such designation and an Officers’ Certificate certifying that such designation
complied with and was permitted by this Section 4.21. 
 Section 4.22 Payments for Consent. 

Neither the Issuer nor any of its Restricted Subsidiaries shall, directly or indirectly, pay or cause to be paid any consideration to or
for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the
Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

 Section 4.23 Reports. 
 (a) Whether or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, the Issuer will furnish to the Trustee and the Holders of Notes or request in writing the Trustee
to furnish to the Holders of Notes: 
 (1) all quarterly and annual reports that would be required to be filed
with the SEC on Forms 10-Q and 10-K if the Issuer were required to file such reports, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” that describes the financial condition and
results of operations of the Issuer and its consolidated Subsidiaries; and 
 (2) all current reports that would
be required to be filed with the SEC on Form 8-K if the Issuer were required to file such reports. 
 in each case, within the time periods
specified in the SEC’s rules and regulations. For purposes of delivery of reports required hereunder, any reports filed with the SEC as contemplated below and available on the SEC’s Electronic Data Gatheric, Analysis and Retrieval system
(EDGAR) or its Interactive Data Electronic Applications system (IDEA), or any successor system for electronic filing, shall be deemed delivered to the Trustee and the Holders of Notes. However, the Trustee shall have no responsibility to determine
if such filing has occurred. 
 (b) All such reports will be prepared in all material respects in accordance with all of the
rules and regulations applicable to such reports. Each annual report on Form 10-K of the Issuer, as applicable, will include a report on the Issuer’s consolidated financial statements by the Issuer’s certified independent accountants. In
addition, the Issuer will post the reports on its website within the time periods specified in the rules and regulations applicable to such reports and, following the consummation of the exchange offer contemplated by the Registration Rights
Agreement, the Issuer will file a copy of each of the reports referred to in clauses (1) and (2) above with the SEC for public availability within those time periods (unless the SEC will not accept such a filing). 

(c) If, at any time after consummation of the exchange offer contemplated by the Registration Rights Agreement, the Issuer is no longer
subject to the periodic reporting requirements of the Exchange Act for any reason, such company will nevertheless continue filing the reports specified in the preceding paragraphs of this covenant with the SEC within the time periods specified above
unless the SEC will not accept such a filing. The Issuer will not take any action for the purpose of causing the SEC not to accept any such filings. 
 (d) The Issuer will hold a quarterly conference call for the Holders of the Notes and securities analysts to discuss such financial information no later than ten Business Days after distribution of such
financial information. 
 (e) If the Issuer has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the
quarterly and annual financial information required by paragraph (a) of this Section 4.23 will include 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. 

  
 61 

 (f) In addition, the Issuer and the Guarantors agree that, for so long as any Notes remain
outstanding, if at any time they are not required or permitted to file with the SEC the reports required by this Section 4.23, they will furnish to the Holders of Notes and to securities analysts and prospective investors, upon its request, the
information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

surviving any such consolidation or merger or the Person to which such sale, assignment, transfer, conveyance or other disposition has been made is not a corporation, such Person causes a corporation to co-issue the Notes and causes such corporation
to enter into appropriate restrictions on its activities consistent with the provision that any such entity will not hold any material assets, become liable for any material obligations or engage in any significant business activities;
provided that such entity may be a co-obligor or guarantor with respect to Indebtedness if the Issuer is an obligor or guarantor on such Indebtedness and the net proceeds of such Indebtedness are received by the Issuer or one or more
Guarantors; 
 (2) the Person formed by or surviving any such consolidation or merger (if other than the Issuer)

indenture and an amendment thereto, respectively; 
 (3) immediately after such transaction, no Default or Event
of Default exists; and 
 (4) the Issuer or the Person, as the case may be, formed by or surviving any such
consolidation or merger (if other than the Issuer), or to which such sale, assignment, transfer, conveyance or other disposition has been made would, on the date of such transaction after giving pro forma effect thereto and any related financing
transactions as if the same had occurred at the beginning of the applicable four-quarter period, be permitted to incur at least $ 1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.14(a)

 Upon any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of the properties or assets of the Issuer or its Restricted
Subsidiaries in a transaction that is subject to, and that complies with the provisions of, Section 5.01 hereof, the successor Person formed by such consolidation or into or with which the Issuer or Restricted Subsidiaries is or are merged or
to which such sale, assignment, transfer, lease, conveyance or other disposition is made 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 the “Issuer” shall refer instead to the successor Person and not to the Issuer or the applicable Restricted Subsidiaries), and may exercise every right and power of the Issuer or
Restricted Subsidiaries under this Indenture with the same effect as if such successor Person had been named as the Issuer or Restricted Subsidiaries herein; provided, however, that the predecessor Issuer or Restricted Subsidiaries shall not
be relieved from the obligation to pay the principal of and interest on the Notes except in the case of a sale of all of the Issuer’s or the applicable Restricted Subsidiaries’ assets in a transaction that is subject to, and that complies
with the provisions of, Section 5.01 hereof. 
 ARTICLE 6 

DEFAULTS AND REMEDIES 

Section 6.01 Events of Default. 
 Each of the following is an “Event of Default”: 

(1) default for 30 days in the payment when due of interest on, or Additional Interest, if any, with respect to, the
Notes; 
 (2) default in the payment when due (at maturity, upon redemption or otherwise) of the principal of, or
premium, if any, on, the Notes; 
 (3) failure by the Issuer or any of the its Restricted Subsidiaries to comply
with the provisions set forth in Sections 3.09, 4.10, 4.11, 4.13, 4.14 or 5.01 hereof; 
 (4) failure by the
Issuer or any of its Restricted Subsidiaries 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 voting as a single class to comply with any of the other
agreements in this Indenture; 
 (5) 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 Issue Date, if that default; 

  
 63 

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

(B) 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 $10.0 million or more; and provided, further, that if such default is cured or waived or any such acceleration rescinded, or such Indebtedness
is repaid, within a period of 10 days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, an Event of Default and any consequential acceleration of the Notes shall be
automatically rescinded, so long as such rescission does not conflict with any judgment or decree; 
 (6) 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 $10.0 million, which judgments are not paid, discharged or stayed for a period of 60 days;

 (7) 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; 

(8) 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 pursuant to or within the meaning of Bankruptcy Law: 
 (A) commences a voluntary case; 
 (B) consents to the entry of an
order for relief against it in an involuntary case; 
 (C) consents to the appointment of a custodian of it or
for all or substantially all of its property; 
 (D) makes a general assignment for the benefit of its creditors;
or 
 (E) generally is not paying its debts as they become due; or 

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

(A) is for relief against 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 in an involuntary case; 
 (B) appoints a custodian 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 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 

  
 64 

 (C) orders the liquidation 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; 
 and the order or decree remains unstayed and in effect for 60 consecutive days. 
 Notwithstanding the above, if the Issuer elects, by giving written notice to the Trustee, the sole remedy for an Event of Default relating to the failure to comply with Section 4.23 hereof, and/or
for failure to comply with the requirements of Section 314(a)(1) of the TIA will, for the 60 days after the occurrence of such an Event of Default, consist exclusively of the right to receive additional interest on the Notes at an annual rate
equal to 0.25% of the principal amount of the Notes then outstanding over such portion of the 60-day period immediately following such Event of Default during which such Event of Default is continuing (such additional interest, “Default
Interest”). In the event the Issuer does not elect to pay the Default Interest, upon an Event of Default to this covenant, the Notes will be subject to acceleration as provided above. Any Default Interest that accrues on all outstanding
Notes from and including the date on which an Event of Default relating to a failure to comply with Section 4.23 hereof and/or for any failure to comply with the requirements of Section 314(a)(1) of the TIA first occurs to, but not
including, the 60th day thereafter (or such earlier date
on which the Event of Default relating to such failure shall have been cured or waived) and will be payable in the same manner as any Additional Interest. On such 60th day (or earlier, if the Event of Default relating to such failure is cured or waived prior to such 60th day) such Additional Interest will cease to accrue and the Notes
will be subject to acceleration, as provided above, if the Event of Default is continuing. This provision will not affect the rights of Holders of Notes in the event of the occurrence of any other Event of Default. For all purposes of the Indenture,
references to interest means interest under the Notes and any Default Interest payable pursuant to this paragraph. 
 Section 6.02
Acceleration. 
 In the case of an Event of Default specified in clause (8) or (9) 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. 
 The Holders of a majority in aggregate principal amount of the then outstanding
Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences under this Indenture except a continuing Default or Event of Default in
the payment of principal, interest, premium or Additional Interest, if any. 
 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, premium,
if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 

  
 65 

 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. 
 Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event
of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or interest on, the Notes (including in connection with an offer to purchase); provided, however,
that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such
Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent
thereon. 
 Section 6.05 Control by Majority. 
 Subject to Section 7.01(e), Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power, including with respect to
the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default if it determines that withholding
notice is in their interest, except a Default or Event of Default relating to the payment of principal, interest, premium or Additional Interest, if any. 
 Section 6.06 Limitation on Suits. 
 Subject to Section 7.01, in
case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any Holders of Notes unless such Holders have offered to the
Trustee an indemnity or security satisfactory to the Trustee against any loss, liability or expense. Except to enforce the right to receive payment of principal, interest, premium, or Additional Interest, if any, when due, no Holder of a Note may
pursue any remedy with respect to this Indenture or the Notes unless: 
 (1) such Holder has previously given the
Trustee written notice that an Event of Default is continuing; 
 (2) Holders of at least 25% in aggregate
principal amount of the then outstanding Notes have requested in writing the Trustee to pursue the remedy; 
 (3)
such Holders have offered the Trustee security or indemnity reasonably satisfactory to it against any loss, liability or expense; 
 (4) the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of security or indemnity; and 

  
 66 

 (5) Holders of a majority in aggregate principal amount of the then
outstanding Notes have not given the Trustee a written direction inconsistent with such request within such 60-day period. 
 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, premium, if
any, and interest 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(1) or (2) hereof occurs and is continuing, the Trustee may recover judgment
(a) in its own name and (b) as trustee of an express trust against the Issuer for the whole amount of principal of, premium, if any, and interest 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 and its respective agents and counsel. 

Section 6.09 Trustee May File Proofs of Claim. 
 The Trustee shall be 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 or 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 or 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. 

  
 67 

 Section 6.10 Priorities. 

If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order:

 First: to the Trustee, the Paying Agent and the Registrar for amounts due under Section 7.07
hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 

Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, and interest,
ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any and interest, respectively; and 

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

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. 

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 the suit, having due
regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more
than 10% in aggregate principal amount of the then outstanding Notes. 
 Section 6.12 Willful Event of Default. 

In the case of any Event of Default occurring by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the
Issuer with the intention of avoiding payment of the premium that the Issuer would have had to pay if the Issuer then had elected to redeem the Notes pursuant Sections 3.09, 4.10 or 4.11 hereof, an equivalent premium will also become and be
immediately due and payable to the extent permitted by law upon the acceleration of the Notes. If an Event of Default occurs by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Issuer with the intention of
avoiding the prohibition on redemption of the Notes prior to that date, then an equivalent premium specified in this Indenture will also become and be immediately due and payable to the extent permitted by law upon the acceleration of the Notes.

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 it must eliminate such conflict within 90 days, apply to the SEC for permission to
continue as Trustee (if this Indenture has been qualified under the TIA) 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.

compensation for their acceptance of this Indenture and services hereunder and thereunder as agreed to in writing between the Trustee and the Issuer. The Trustee’s compensation will not be limited by any law on compensation of a Trustee of an
express trust. The Issuer will reimburse each Indemnified Party 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 Indemnified Party’s agents and counsel. 
 (b) The Issuer and
the Guarantors will indemnify the Indemnified Party against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and
expenses of enforcing this Indenture 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, except to the extent any such loss, liability or expense may be attributable to its negligence or willful misconduct. The Indemnified Party will notify the Issuer
promptly of any claim for which it may seek indemnity. Failure by the Indemnified Party to so notify the Issuer will not relieve the Issuer or any of the Guarantors of their obligations hereunder. The Issuer or such Guarantor will defend the claim
and the Indemnified Party will cooperate in the defense. The Indemnified Party may have separate counsel and the Issuer will pay the reasonable fees and expenses of one such counsel. Neither the Issuer nor any Guarantor need pay for any settlement
made without its consent, which consent will 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. 
 (d) To secure the
Issuer’s and the Guarantors’ payment obligations in this Section 7.07, each Indemnified Party will have a Lien prior to the Notes on all money or property held or collected by the Trustee, in its capacity as Trustee, except, in the
case of the Trustee, that held in trust to pay principal, premium, if any, and interest on particular Notes pursuant to Article 8 hereof. Such Lien will survive the satisfaction and discharge of this Indenture. 

(e) When an Indemnified Party incurs expenses or renders services after an Event of Default specified in Section 6.01(8) or
(9) 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. 

(f) The Trustee will comply with the provisions of TIA § 313(b)(2) to the extent applicable. 

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. 

  
 71 

 (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 not less than 30 days prior to the effective date
of such removal. The Issuer may remove the Trustee if: 
 (1) the Trustee fails to comply with Section 7.10
hereof; 
 (2) 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; 
 (3) a custodian or public officer takes charge of the Trustee or its
property; or 
 (4) 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, 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 mail 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. 
 (g) The
retiring Trustee shall have no responsibility or liability for any action or inaction of a successor 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, the successor corporation without any further act will be the successor Trustee. As soon as practicable, the successor Trustee shall mail a notice of its succession to the Issuer and the Holders
of Notes. Any such successor must nevertheless be eligible and qualified under the provisions of Section 7.10 hereof. 

  
 72 

 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 $50.0
million as set forth in its most recent published annual report of condition. 
 This Indenture will always have a Trustee who
satisfies the requirements of TIA § 310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b); provided, however, that there shall be excluded from the operation of TIA § 310(b)(1) any indenture
or indentures under which other securities, or certificates of interest or participation in other securities, of the Issuer are outstanding, if the requirements for such exclusion set forth in TIA § 310(b)(1) are met. 

Section 7.11 Preferential Collection of Claims Against Issuer. 
 The Trustee is subject to TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA
§ 311(a) to the extent indicated therein. 
 Section 7.12 Trustee in Other Capacities; Paying Agent. 

References to the Trustee in Sections 7.01(b), (d), (f), (g) and (h), 7.02, 7.03, 7.04, 7.07, and 7.08 shall be understood to
include the Trustee when acting in its other capacities under this Indenture, including, without limitation, as Paying Agent. The privileges, rights, indemnities, immunities and exculpatory provisions contained in this Indenture shall apply to the
Trustee, whether it is acting under this Indenture or the other Indenture Documents. 
 ARTICLE 8 

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 the Board of Directors of the Issuer, 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 8. 
 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 in Section 8.04 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 8.06 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) 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: 

  
 73 

 (1) the rights of Holders of outstanding Notes to receive payments in
respect of the principal of, and interest, premium and Additional Interest, if any, on, such Notes when such payments are due from the trust referred to in Section 8.05 hereof; 

(2) the Issuer’s obligations with respect to the Notes under Article 2 and Section 4.02 hereof; 

(3) the rights, powers, trusts, duties and immunities of the Trustee, and the Issuer’s and the Guarantors’
obligations in connection therewith; and 
 (4) this Article 8. 

Subject to compliance with this Article 8, 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 obligations under the covenants contained in Sections 3.09, 4.08, and 4.10 through and including 4.22 hereof;
clause (4) of Section 5.01 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. 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, the breach or non compliance with the covenants defeased pursuant to this Section 8.03 hereof will not constitute Events of Default. 
 Section 8.04 Conditions to Legal or Covenant Defeasance. 
 In order to
exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof: 
 (1) the
Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of Notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in
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, and interest, premium and Additional 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; 

  
 74 

 (2) in the case of Legal Defeasance, the Issuer must deliver to the Trustee
an Opinion of Counsel confirming that (a) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (b) 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; 

(3) in the case of Covenant Defeasance, the Issuer must deliver to the Trustee an Opinion of Counsel 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; 
 (4) 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 incurrence of Indebtedness or the grant of Liens securing such Indebtedness, all or a portion of the proceeds of which will be
used to defease the Notes pursuant to this Article 8 concurrently with such incurrence); 
 (5) 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) to which the Issuer or any of its Subsidiaries is a party or by which the
Issuer or any of its Subsidiaries is bound; 
 (6) 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 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 
 (7) 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 (i) held in trust, (ii) at the
written direction of the Issuer, such money may be invested, prior to maturity of the Notes, in Government Securities, and (iii) 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, premium, if any, and interest, 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. 

  
 75 

 Notwithstanding anything in this Article 8 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(1) 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 Issuer. 

Subject to any unclaimed property law, 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, premium, if any, or interest on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Issuer or (if then held by the
Issuer) will be discharged from such trust; and the Holder of such Note will thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust
money or Government Securities, 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 or The Wall Street Journal, 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. 
 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 Section 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 Section 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 Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Issuer or any Guarantor make any payment of principal of, premium, if any, or interest 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 or Government Securities held by the Trustee or Paying Agent. 

ARTICLE 9 

AMENDMENT, SUPPLEMENT AND WAIVER 

Section 9.01 Without Consent of Holders of Notes. 
 Notwithstanding Section 9.02 hereof, without the consent of any Holder, the Issuer, the Guarantors and the Trustee, may amend or supplement this Indenture, the Notes or the Note Guarantees:

 (1) to cure any ambiguity, defect or inconsistency; 

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

  
 76 

 (3) to provide for the assumption of the Issuer’s or a Guarantor’s
obligations to Holders of Notes and Note Guarantees in the case of a merger or consolidation or sale of all or substantially all of the Issuer’s or such Guarantor’s assets, as applicable pursuant to Article 5; 

(4) to make any change that would provide any additional rights or benefits to the Holders of Notes or that does not
adversely affect the legal rights under this Indenture, the Notes or the Note Guarantees of any such Holder; 

(5) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the
TIA; 
 (6) to conform the text of this Indenture, the Notes, or the Note Guarantees to any provision of the
“Description of Notes” section of the Offering Memorandum to the extent that such provision was intended to be a verbatim recitation of a provision of this Indenture, the Notes or the Note Guarantees as certified by an Officer’s
Certificate delivered to the Trustee; 
 (7) to provide for the issuance of Additional Notes in accordance with
the limitations set forth in this Indenture as of the Issue Date (including Section 4.14); or 
 (8) to
allow any Guarantor to execute a supplemental indenture and/or a Note Guarantee with respect to the Notes or to release any Guarantor in accordance with the terms of this Indenture. 
 Section 9.02 With Consent of Holders of Notes. 
 Except as provided in
section 9.01 and in the next succeeding paragraph of this Section 9.02, this Indenture, the Notes or the Note Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the
Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), and any existing Default or Event of Default or compliance with any provision of this
Indenture, 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, consents obtained in connection with a purchase of,
or tender offer or exchange offer for, Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02. 

Without the consent of each Holder of Notes, an amendment, supplement or waiver may not: 

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

(2) reduce the principal of or change the fixed maturity of any Note or alter the provisions with respect to the
redemption or repurchase of the Notes (other than provisions relating to the covenants contained in Sections 3.09, 4.10 and 4.11 hereof); 
 (3) reduce the rate of or change the time for payment of interest, including Default Interest, on any Note; 
 (4) waive a Default or Event of Default in the payment of principal of, or interest, premium or Additional Interest, if any, on, the Notes (except a rescission of acceleration of the Notes by the Holders
of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration); 

  
 77 

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

 (6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of
Holders of Notes to receive payments of principal of, or interest, premium or Additional Interest, if any, on, the Notes; 
 (7) waive a redemption or repurchase payment with respect to any Note (other than a payment required by Sections 4.10 or 4.11 hereof); 

(8) release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance
with the terms of this Indenture; or 
 (9) make any change in the preceding amendment, supplement and waiver
provisions. 
 Section 9.03 Compliance with TIA. 
 Every amendment or supplement to this Indenture or the Notes will be set forth in an amended or supplemental indenture that complies with the TIA as then in effect. 

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 in accordance with Section 12.02 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. 
 The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders
entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies),
and only those Persons, shall be entitled to consent to such amendment or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. 

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. 

  
 78 

 Section 9.06 Trustee to Sign Amendments, etc. 

Upon the request of the Issuer, accompanied by a resolution of the Board of Directors authorizing the execution of any such amended or
supplemental indenture, and upon the filing with the Trustee of evidence of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 or this Section 9.06 hereof, the
Trustee shall join with the Issuer and the Guarantors in the execution of such amended or supplemental indenture. 
 It shall
not be necessary for the consent of Holders of Notes under Sections 9.01 or 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 

After an amendment, supplement or waiver under this Section 9.06 becomes effective, the Issuer shall send to the Holders of Notes
affected thereby a notice briefly describing the amendment, supplement or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in principal amount of the Notes then outstanding may waive compliance in a particular instance by
the Issuer with any provision of this Indenture of the Notes. 
 The Trustee will sign any amended or supplemental indenture
authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuer may not sign an amended or supplemental indenture until the Board of Directors of
the Issuer approves it. In executing any amended or supplemental indenture, the Trustee will 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. 

ARTICLE 10 

SATISFACTION AND DISCHARGE 

Section 10.01 Satisfaction and Discharge. 
 This Indenture will be discharged and will cease to be of further effect as to all Notes and Note Guarantees issued hereunder and the Trustee, on demand and at the expense of the Issuer, will execute
proper instruments acknowledging satisfaction and discharge of this Indenture, when: 
 (1) either: 

(a) 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 
 (b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the delivering of a notice of redemption or otherwise or will become due and payable
within one year and 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 of cash in U.S. dollars and non-callable Government Securities, in 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, interest, premium and Additional Interest, if any, to the date of maturity or redemption; 
 (2) no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit
or 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; 

  
 79 

 (3) the Issuer has or any Guarantor has paid or caused to be paid all sums
payable by it under this Indenture; and 
 (4) the Issuer has delivered irrevocable instructions to the Trustee
under this Indenture to apply the deposited money toward the payment of the Notes at 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 money has been deposited with the Trustee pursuant to
subclause (b) of clause (1) of this Section 10.01, the provisions of Sections 10.02 and 8.06 hereof will survive. In addition, nothing in this Section 10.01 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 10.02 Application of Trust Money.

 Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 10.01
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 (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money 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 10.01 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 10.01 hereof; provided that if the Issuer has made any payment of principal of, premium, if any, or
interest 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.

 ARTICLE 11 
 GUARANTEES 
 Section 11.01 Guarantee. 

(a) Subject to Section 11.02, each of the Guarantors hereby, jointly and severally, unconditionally guarantees on a senior unsecured
basis to the extent, with respect to security, set forth in Article 12, to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its respective successors and assigns, irrespective of the validity and enforceability
of this Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that: 
 (1) the principal
of, premium, if any, and interest on, the Notes will be promptly paid in full when due, subject to any applicable grace period, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on
the Notes, if any, if lawful, and all other obligations of the Issuer to the Holders and the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 

  
 80 

 (2) in case of any extension of time of payment or renewal of any Notes or
any of such other obligations, the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, 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 the Issuer or any Guarantor 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, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 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 (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 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
Guarantee. 
 Section 11.02 Limitation on Guarantor Liability. 

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms 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 

  
 81 

 
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 11, result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent transfer or conveyance. 
 Section 11.03 Execution and Delivery of Guarantee. 
 To evidence its
Note Guarantee set forth in Section 11.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form attached as Exhibit E hereto will be signed by an Officer of such Guarantor (by manual or facsimile
signature) on each Note authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its Officers. 
 Each Guarantor hereby agrees that its Guarantee set forth in Section 11.01 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 this Indenture or on the Note Guarantee no longer holds that office at the
time the Trustee authenticates the Note on which a 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 Domestic Subsidiary after the Issue Date, if required by Section 4.20 hereof, the Issuer will cause such Domestic Subsidiary to comply with the provisions of Section 4.20 hereof and this Article 11, to the extent
applicable. 
 Section 11.04 Guarantors May Consolidate, etc., on Certain Terms. 

Except as otherwise provided in Section 11.05 hereof, a Guarantor may not transfer, sell or otherwise dispose of all or
substantially all of its 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: 

(1) immediately after giving effect to that transaction, no Default or Event of Default exists; and 

(2) either: 
 (a) subject to Section 11.05 hereof, the Person acquiring the property in any such transfer, sale or disposition or the Person formed by or surviving any such consolidation or merger assumes all the
obligations of that Guarantor under this Indenture and its Note Guarantee pursuant to a supplemental indenture and an amendment to the Registration Rights Agreement; or 

(b) the Net Proceeds of such transfer, sale or other disposition are applied in accordance with the applicable provisions
of this Indenture; 

  
 82 

 provided, however, that the transfer, sale or other disposition of assets of the Guarantors that
would comprise all or substantially all of the assets of the Issuer, or the consolidation or merger into another person, of the Guarantors which would comprise all or substantially all of the assets of the Issuer will be governed by Article 5 hereof
and may be subject to Section 4.10 hereof. 
 In case of any such consolidation, merger, sale or conveyance 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 endorsed upon the Notes 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 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. 
 Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses 2(a) and (b) above,
nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into any Issuer or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or
substantially as an entirety to any Issuer or another Guarantor. 
 Section 11.05 Releases. 

The Note Guarantee of a Guarantor will be released: 

(1) in connection with any transfer, sale or other disposition of all or substantially all of the assets of that Guarantor
(including by way of merger or consolidation) 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 transfer, sale or other disposition does not violate
Section 4.11 hereof with respect to that Guarantor and Sections 4.10 and 5.01 hereof as contemplated in the proviso of the first paragraph in Section 11.04 hereof; 

(2) in connection with any transfer, sale or other disposition of all of the 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 4.11 hereof with respect to Guarantors, as contemplated in the
proviso to Section 11.04; 
 (3) if the Issuer designates that Guarantor to be an Unrestricted Subsidiary in
accordance Section 4.21 hereof; 
 (4) upon Legal Defeasance or Satisfaction and Discharge of this Indenture
in Accordance with Articles 8 and 10 hereof; or 
 (5) as may be provided in any intercreditor agreement we enter
into in connection with any current and future Credit Facilities. 
 Any Guarantor not released from its obligations under its
Guarantee as provided in this Section 11.05 will, subject to Section 11.02, remain liable for the full amount of principal of and interest and premium, if any, on the Notes and for the other obligations of any Guarantor under this

 [Back of Note] 
 9% Senior Notes due 2019 
 Capitalized terms used herein have the meanings
assigned to them in the Indenture referred to below unless otherwise indicated. 
 (1)
INTEREST. Forbes Energy Services Ltd., a Bermuda exempt company (the “Issuer”), promises to pay interest on the principal amount of this Note at a rate of 9% per annum, from June 7,
2011 until maturity. The Issuer will pay interest semi-annually in arrears on June 15 and December 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 (each, a “Record Date”) 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 December 15, 2011. The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal, premium, if any, and
interest (without regard to any applicable grace period), from time to time on demand at a rate equal to 2% per annum in excess of the then applicable interest rate on the Notes to the extent lawful. 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 mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. The Issuer will pay Additional Interest, if any, to Holders of Notes pursuant to
the Registration Rights Agreement. Defaulted interest and Additional Interest, if any, will be paid on regular Interest Payment Dates in the same manner as other interest is paid on the Notes. All reference to “interest” in this Note and
the Indenture mean the initial interest rate borne by the Notes and any increases in that rate due to defaulted interest or Additional Interest (unless the Indenture states otherwise). Defaulted interest and Additional Interest will be in addition
to any other interest payable from time to time with respect to the Notes. 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 Holders at the close of business on June 1 or December 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 Sections 2.12 and 6.01 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest 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 mailed to the Holders at their addresses set forth in the register of Holders; provided that (1) payment by wire transfer of immediately available
funds will be required with respect to principal of, interest and premium, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Issuer or the Paying Agent and (2) such
payment by check may only be paid so long as no event of default under the Indenture is continuing. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and
private debts. The principal of the Notes shall be payable only upon 

  
 A-4

 
surrender of any Note at the specified offices of the Paying Agent. If the due date for payment of the principal in respect of any Note is not a Business Day at the place in which it is presented
for payment, the Holder thereof shall not be entitled to payment of the amount due until the next succeeding Business Day at such place. 
 (3) PAYING AGENT AND REGISTRAR. Initially, Wells Fargo Bank, National Association, the Trustee under the Indenture, will
act as Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer or any of its Subsidiaries may act in any such capacity; provided no Event of Default is continuing. 

(4) INDENTURE; REGISTRATION RIGHTS
AGREEMENT. The Issuer issued the Notes under an Indenture dated as of June 7, 2011 (the “Indenture”) among the Issuer, the Guarantors and the Trustee. The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, which applies to the Indenture and is incorporated by reference therein. The Notes are subject to all such terms, and Holders
are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are
unsecured obligations of the Issuer. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder. Holders are entitled to the benefits of the Registration Rights Agreement. 

(5) RANKING. This Note shall constitute a senior obligation of the Issuer and the
Obligations of the Issuer under the Indenture and this Note shall be secured pursuant to the Collateral Documents and will be subject to the Intercreditor Agreement, if any. 

(6) OPTIONAL REDEMPTION AND PURCHASE.
The Notes are subject to redemption and purchase as provided in Article III of the Indenture. 
 (7)
MANDATORY REDEMPTION. The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes. 

(8) REPURCHASE AT THE OPTION OF
HOLDER. 
 (a) If there is a Change of Control, the Issuer will be required to
make a Change of Control Offer to each Holder to repurchase all or any part (equal to minimum amounts of $2,000 and integral multiples of $1,000 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 and Additional 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 10 days following any Change of Control or, at the Issuer’ option, prior to such Change of Control but after public announcement thereof, 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 an Asset Sale, the Issuer in circumstances
specified in the Indenture may be required to commence an offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in the Indenture with respect to
offers to purchase or redeem with the proceeds of sales of assets an Asset Sale Offer pursuant to Section 3.09 of the Indenture to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be
purchased out of the Excess Proceeds at an offer price in cash in an 

  
 A-5

 
amount equal to 100% of the principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of purchase, in accordance with the procedures set forth
in the Indenture. Holders of 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. 
 (9) NOTICE
OF REDEMPTION. Notice of redemption will be mailed at least 30 days but not more than 60 days before the redemption date 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 or discharge of the Indenture. Notes in denominations larger than $2,000 may be
redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. 
 (10) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral
multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee 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 and fees required by law or permitted by the Indenture. The Issuer need 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 need not exchange or register the transfer of any Notes for a period of 15 days prior to the mailing of a notice of redemption of the Notes to be redeemed or during the
period between a record date and the corresponding Interest Payment Date. 
 (11) PERSONS
DEEMED OWNERS. The Holder of a Note may be treated as its owner for all purposes. Only Holders have rights under the Indenture and this Note. 

(12) AMENDMENT, SUPPLEMENT AND WAIVER.
Subject to certain exceptions, the Indenture, the Notes or the Note Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes, voting as a single
class, and any existing Default or Event of Default or compliance with any provision of the Indenture, 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, voting as a single class. Without the consent of any Holder of a Note, the Indenture, the Notes or the Note Guarantees may be amended or supplemented to cure any ambiguity, defect or inconsistency and to effect certain other changes as set
forth in the Indenture. 
 (13) DEFAULTS AND
REMEDIES. If any 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. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. 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 Trustee in its exercise of any trust or power.
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 interest or premium, if any,) if it determines that withholding
notice is in their interest. The Holders of a 

  
 A-6

 
majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing
Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest or premium, if any, on, or the principal of, the Notes. The Issuer are required to deliver to the Trustee
annually a statement regarding compliance with the Indenture, and the Issuer are required, upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 

(14) TRUSTEE DEALINGS WITH THE
ISSUER. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Issuer or its Affiliates, and may otherwise deal with the Issuer or its Affiliates,

and Wells Fargo Bank, National Association, as trustee under the Indenture referred to below (the “Trustee”). 

W I T N E S S E T H 
 WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of June 7, 2011 providing for the issuance of 9% Senior Notes due
2019 (the “Notes”); 
 WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing
Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Company’s Obligations under the Notes and the Indenture on the terms and
conditions set forth herein (the “Guarantee”); and 
 WHEREAS, pursuant to Section 9.01 of the Indenture,
the Trustee is authorized to execute and deliver this Supplemental Indenture. 
 NOW, THEREFORE, in consideration of the
foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:

 1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings
assigned to them in the Indenture. 
 2. AGREEMENT TO GUARANTEE. The Guaranteeing
Subsidiary hereby agrees to provide an unconditional Guarantee on the terms and subject to the conditions set forth in the Guarantee and in the Indenture including but not limited to Article 11 thereof, and subject to the limitations therein.

 3. NO RECOURSE AGAINST OTHERS. No director, officer, employee,
incorporator or stockholder of the Company or any Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the Notes, the Indenture or the Note Guarantees or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not be effective to waive
liabilities under the federal securities laws. 
 4. NEW YORK LAW TO GOVERN. THE LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE
USED TO CONSTRUE THE INDENTURE, THE NOTES AND THE NOTE GUARANTEES. 
 5. COUNTERPARTS. The parties may sign any
number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. 
 6. EFFECT OF HEADINGS. The Section headings herein are for convenience only and shall not affect the construction hereof.
