 NORANDA ALUMINUM ACQUISITION CORPORATION 
 Senior Floating Rate Note due 2015 
  

	1.	Interest 

 (a) NORANDA ALUMINUM ACQUISITION CORPORATION, a Delaware
corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security semiannually in arrears on
each May 15 and November 15 commencing on November 15, 2007. Interest on the Securities will accrue from the Issue Date or the most recent date to which interest has been paid or provided for until the principal hereof is due;
provided that interest with respect to a PIK Payment (as defined below) will accrue in accordance with the terms discussed below. Interest shall be computed on the basis of a 360-day year of twelve 30-day months. 
 Interest for the first Interest Period commencing on the Issue Date shall be payable in cash. For any Interest Period following such first Interest Period through
May 15, 2011, the Company may, at its option, elect to pay interest on the Securities (i) entirely in cash (“Cash Interest”), (ii) entirely by increasing the principal amount of the outstanding Securities or by issuing
Additional Securities (“PIK Interest”) or (iii) 50% as Cash Interest and 50% as PIK Interest. The Company must elect the form of interest payment with respect to each Interest Period by delivering a notice to the Trustee prior to the
beginning of each Interest Period. The Trustee shall promptly deliver a corresponding notice to the holders. In the absence of such an election for any Interest Period, interest on the Securities will be payable in the form of the interest payment
for the prior Interest Period. After May 15, 2011, the Company will make all interest payments on the Securities in Cash Interest only. 
 Cash Interest
on the Securities will accrue at a rate per annum, reset semiannually, equal to LIBOR plus 4.00%, as determined by the Calculation Agent. PIK Interest on the Securities will accrue at the Cash Interest rate per annum plus 0.75% and be payable
(x) with respect to the Securities represented by one or more global notes registered in the name of, or held by, The Depository Trust Company (“DTC”) or its nominee on the relevant record date, by increasing the principal amount of
the outstanding Securities represented by such global notes by an amount equal to the amount of PIK Interest for the applicable Interest Period (rounded up to the nearest whole dollar) (and/or by issuing new global notes authenticated and delivered
by the Trustee) and (y) with respect to Securities represented by certificated notes, by issuing Additional Securities in certificated form in an aggregate principal amount equal to the amount of PIK Interest for the applicable Interest Period
(rounded up to the nearest whole dollar) and the Trustee will, at the request of the Company, authenticate and deliver such Additional Securities in certificated form for original issuance to the holders on the relevant record date, as shown by the
Register. The payment of PIK Interest according to sections (x) and (y) of this paragraph shall be known as a “PIK Payment.” 
 Following
an increase in the principal amount of the outstanding Securities represented by global notes as a result of a PIK Payment, such Securities will bear interest on such increased principal amount from and after the date of such PIK Payment. Any
Additional Securities issued in certificated form will be 

 
dated as of the applicable interest payment date and will bear interest from and after such date. All Additional Securities issued pursuant to a PIK Payment
will mature on May 15, 2015 and will be governed by, and subject to the terms, provisions and conditions of, the Indenture and shall have the same rights and benefits as the Securities issued on the Issue Date. Any certificated Additional
Securities will be issued with the description “PIK” on the face of each such Additional Security. 
 The amount of interest for each day that the
Securities are outstanding (the “Daily Interest Amount”) will be calculated by dividing the interest rate in effect for such day by 360 and multiplying the result by the principal amount of the Securities. The amount of interest to be paid
on the Securities for each Interest Period will be calculated by adding the Daily Interest Amounts for each day in the Interest Period. 
 All percentages
resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point being rounded upwards (e.g., 9.876545% (or .09876545) being
rounded to 9.87655% (or .0987655)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards). 
 The interest rate on the Securities will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application. 
 The Calculation Agent will, upon the request of any holder of Securities, provide the interest rate then in effect with respect to the Securities. 
 Additional interest is payable with respect to the Securities in certain circumstances if the Company does not consummate the exchange offer (or shelf registration, if
applicable) pursuant to the terms of the Registration Rights Agreement between the Company, the Guarantors and the Initial Purchasers entered into as of the date hereof. Any additional interest on the Securities will be payable in the same form of
payment elected by the Company for the payment of interest with respect to the applicable Interest Period. 
 “Calculation Agent” means a financial
institution appointed by the Company to calculate the interest rate payable on the Securities in respect of each Interest Period, which shall initially be the Trustee. 
 “Determination Date” with respect to an Interest Period will be the second London Banking Day preceding the first day of such Interest Period. 
 “Initial Purchasers” means Merrill Lynch, Pierce, Fenner & Smith Incorporated, Citigroup Global Markets Inc., Goldman, Sachs & Co., UBS Securities LLC, and KeyBanc Capital Markets Inc., and
such other initial purchasers party to the Purchase Agreement entered into in connection with the offer and sale of the Securities. 
 “Interest
Period” means the period commencing on and including an interest payment date and ending on and including the day immediately preceding the next succeeding interest payment date, with the 

 
exception that the first Interest Period shall commence on and include the Issue Date and end on and include November 14, 2007. 
 “Issue Date” means the date on which the Securities are originally issued. 
 “LIBOR,” with respect to an Interest Period, will be the rate (expressed as a percentage per annum) for deposits in U.S. dollars for a six-month period beginning on the second London Banking Day after the
Determination Date that appears on Telerate Page 3750 as of 11:00 a.m., London time, on the Determination Date. If Telerate Page 3750 does not include such a rate or is unavailable on a Determination Date, the Calculation Agent will request the
principal London office of each of four major banks in the London interbank market, as selected by the Calculation Agent, to provide such bank’s offered quotation (expressed as a percentage per annum), as of approximately 11:00 a.m., London
time, on such Determination Date, to prime banks in the London interbank market for deposits in a Representative Amount in U.S. dollars for a six-month period beginning on the second London Banking Day after the Determination Date. If at least two
such offered quotations are so provided, the rate for the Interest Period will be the arithmetic mean of such quotations. If fewer than two such quotations are so provided, the Calculation Agent will request each of three major banks in New York
City, as selected by the Calculation Agent, to provide such bank’s rate (expressed as a percentage per annum), as of approximately 11:00 a.m., New York City time, on such Determination Date, for loans in a Representative Amount in U.S. dollars
to leading European banks for a six-month period beginning on the second London Banking Day after the Determination Date. If at least two such rates are so provided, the rate for the Interest Period will be the arithmetic mean of such rates. If
fewer than two such rates are so provided, then the rate for the Interest Period will be the rate in effect with respect to the immediately preceding Interest Period. 
 “London Banking Day” is any day on which dealings in U.S. dollars are transacted or, with respect to any future date, are expected to be transacted in the London interbank market. 
 (b) Registration Rights Agreement. If this Security is an “Original Security” (as defined in the Indenture), the holder of this Security is entitled to the
benefits of a Registration Rights Agreement, dated as of May 18, 2007, among the Company, the Guarantors and the Initial Purchasers. 
  

	2.	Method of Payment 

 The Company shall pay interest on the Securities
(except defaulted interest) to the Persons who are registered Holders at the close of business on the May 1 or November 1 next preceding the interest payment date even if Securities are canceled after the record date and on or before the
interest payment date (whether or not a Business Day). Holders must surrender Securities to the Paying Agent to collect principal payments. The Company shall pay principal, premium, if any, and interest in money of the United States of America that
at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium, if any, and interest) shall be made by wire transfer of immediately
available funds to the accounts specified by The Depository Trust Company or any successor depositary. The Company shall make all payments in respect of a certificated Security (including principal, premium, if any, and 

 
interest), at the office of the Paying Agent, except that, at the option of the Company, payment of interest may be made by mailing a check to the registered
address of each Holder thereof; provided, however, that payments on the Securities may also be made, in the case of a Holder of at least $1,000,000 aggregate principal amount of Securities, by wire transfer to a U.S. dollar account
maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or Paying Agent to such effect designating such account no later than 30 days immediately preceding the
relevant due date for payment (or such other date as the Trustee may accept in its discretion). 
  

	3.	Paying Agent and Registrar 

 Initially, Wells Fargo Bank, National
Association, a national banking association (the “Trustee”), will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent or Registrar without notice. The Company or any of its domestically incorporated
Wholly Owned Subsidiaries may act as Paying Agent or Registrar. 
  

	4.	Indenture 

 The Company issued the Securities under an Indenture
dated as of May 18, 2007 (the “Indenture”), among the Company, the Guarantors party thereto (the “Guarantors”) and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “TIA”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto
in the Indenture. The Securities are subject to all terms and provisions of the Indenture, and the Holders (as defined in the Indenture) are referred to the Indenture and the TIA for a statement of such terms and provisions. 
 The Securities are senior unsecured obligations of the Company. This Security is one of the Original Securities referred to in the Indenture. The Securities include the
Original Securities, any issued Add-On Securities and any Exchange Securities issued in exchange for the Original Securities or the Add-On Securities pursuant to the Indenture (including in all instances any Additional Securities issued as a result
of a PIK Payment for any of the foregoing). The Original Securities, any Add-On Securities and any Exchange Securities (including in all instances any Additional Securities issued as a result of a PIK Payment for any of the foregoing) are treated as
a single class of securities under the Indenture. The Indenture imposes certain limitations on the ability of the Company and its Restricted Subsidiaries to, among other things, make certain Investments and other Restricted Payments, pay dividends
and other distributions, incur Indebtedness, enter into consensual restrictions upon the payment of certain dividends and distributions by such Restricted Subsidiaries, issue or sell shares of Capital Stock of the Company and such Restricted
Subsidiaries, enter into or permit certain transactions with Affiliates, create or incur Liens and make Asset Sales. The Indenture also imposes limitations on the ability of the Company and each Guarantor to consolidate or merge with or into any
other Person or convey, transfer or lease all or substantially all of its property. 

 To guarantee the due and punctual payment of the principal and interest on the Securities and all other amounts payable
by the Company under the Indenture and the Securities when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Securities and the Indenture, the Guarantors have, jointly and
severally, unconditionally guaranteed the Guaranteed Obligations on a senior unsecured basis pursuant to the terms of the Indenture. 
  

	5.	Optional Redemption 

 Except as set forth in the following two
paragraphs, the Securities shall not be redeemable at the option of the Company prior to May 15, 2008. Thereafter, the Securities shall be redeemable at the option of the Company, in whole at any time or in part from time to time, upon not less
than 30 nor more than 60 days’ prior notice delivered electronically or by first-class mail to each Holder’s registered address, at the following redemption prices (expressed as a percentage of principal amount), plus accrued and unpaid
interest and additional interest, if any, to the redemption date (subject to the right of the Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the twelve-month period
commencing on May 15 of the years set forth below: 
  

			
	 Year
	  	Redemption Price
	 2008
	  	102.000%
	 2009
	  	101.000%
	 2010 and thereafter
	  	100.000%

 In addition, prior to May 15, 2008, the Company may redeem the Securities at its option, in whole at any time
or in part from time to time, upon not less than 30 nor more than 60 days’ prior notice electronically delivered or mailed by first-class mail to each Holder’s registered address, at a redemption price equal to 100% of the principal amount
of the Securities redeemed plus the Applicable Premium as of, and accrued and unpaid interest and Additional Interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on
the relevant interest payment date). 
 Notwithstanding the foregoing, at any time and from time to time on or prior to May 15, 2008, the Company may
redeem in the aggregate up to 35% of the original aggregate principal amount of the Securities (calculated after giving effect to any issuance of Additional Securities), with the net cash proceeds of one or more Equity Offerings (1) by the
Company or (2) by any direct or indirect parent of the Company, in each case, to the extent the net cash proceeds thereof are contributed to the common equity capital of the Company or used to purchase Capital Stock (other than Disqualified
Stock) of the Company from it, at a redemption price (expressed as a percentage of principal amount thereof) of 100% plus a premium (expressed as a percentage of principal amount thereof) equal to the interest rate per annum on the Securities
applicable on the date on which notice of redemption is given, plus accrued and unpaid interest and Additional Interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on
the relevant interest payment date); provided, however, that at least 50% of the original aggregate principal amount of the Securities 

 
(calculated after giving effect to any issuance of Additional Securities) must remain outstanding after each such redemption; and provided, further,
that such redemption shall occur within 90 days after the date on which any such Equity Offering is consummated upon not less than 30 nor more than 60 days’ notice electronically delivered or mailed to each Holder of Securities being redeemed
and otherwise in accordance with the procedures set forth in the Indenture. Notice of any redemption upon any Equity Offering may be given prior to the completion of such Equity Offering, and any such redemption or notice may, at the Company’s
discretion, be subject to one or more conditions precedent, including, but not limited to, completion of the related Equity Offering. 
  

	6.	Mandatory Redemption and Sinking Fund 

 The Securities are not
subject to any sinking fund. If the Securities would otherwise constitute “applicable high yield discount obligations” within the meaning of Section 163(i)(1) of the Internal Revenue Code of 1986, as amended (the “Code”), at
the end of each accrual period ending after the fifth anniversary of the Securities’ issuance (each, an “AHYDO redemption date”), the Company will be required to redeem for cash a portion of each Security then outstanding equal to the
“Mandatory Principal Redemption Amount” (each such redemption, a “Mandatory Principal Redemption”). The redemption price for the portion of each Security redeemed pursuant to a Mandatory Principal Redemption will be 100% of the
principal amount of such portion plus any accrued interest thereon on the date of redemption. The “Mandatory Principal Redemption Amount” means the portion of a Security required to be redeemed to prevent such Security from being treated
as an “applicable high yield discount obligation” within the meaning of Section 163(i)(1) of the Code. No partial redemption or repurchase of the Security prior to an AHYDO redemption date pursuant to any other provision of the
Indenture will alter the Company’s obligation to make the Mandatory Principal Redemption with respect to Securities that remain outstanding on an AHYDO redemption date. 
  

	7.	Notice of Redemption 

 Notice of redemption will be electronically
delivered or mailed by first-class mail at least 30 days but not more than 60 days before the redemption date to each Holder of Securities to be redeemed at his, her or its registered address. Securities in denominations larger than $2,000 may be
redeemed in part but only in whole multiples of $1,000, except that Additional Securities issued as a result of a PIK Payment may be issued in denominations of $1.00 and any integral multiple thereof, and any increase in the principal amount of
Securities as a result of a PIK Payment may be made in integral multiples of $1.00. If money sufficient to pay the redemption price of and accrued and unpaid interest on all Securities (or portions thereof) to be redeemed on the redemption date is
deposited with a Paying Agent on or before the redemption date and certain other conditions are satisfied, on and after such date interest ceases to accrue on such Securities (or such portions thereof) called for redemption. 

	8.	Repurchase of Securities at the Option of the Holders upon Change of Control and Asset Sales 

 Upon the occurrence of a Change of Control, each Holder shall have the right, subject to certain conditions specified in the Indenture, to cause the Company to repurchase all or any part of such Holder’s
Securities at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of the Holders of record on the relevant record date to receive interest
due on the relevant interest payment date), as provided in, and subject to the terms of, the Indenture. 
 In accordance with Section 4.06 of the
Indenture, the Company will be required to offer to purchase Securities upon the occurrence of certain events. 
  

	9.	Ranking  

 The Securities and the Guarantees are senior unsecured
obligations of the Company and the Guarantors and will be of equal ranking with all present and future senior unsecured indebtedness. 
  

	10.	Denominations; Transfer; Exchange 

 The Securities are in registered
form, without coupons, in denominations of $2,000 and any integral multiple of $1,000, except that Additional Securities issued as a result of a PIK Payment may be issued in denominations of $1.00 and any integral multiple thereof, and any increase
in the principal amount of the Securities as a result of a PIK Payment may be made in integral multiples of $1.00. A Holder shall register the transfer of or exchange of Securities in accordance with the Indenture. Upon any registration of transfer
or exchange, the Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes required by law or permitted by the Indenture. The Registrar need not register the
transfer of or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or to transfer or exchange any Securities for a period of 15 days prior to a
selection of Securities to be redeemed. 
  

	11.	Persons Deemed Owners 

 The registered Holder of this Security shall
be treated as the owner of it for all purposes. 
  

	12.	Unclaimed Money 

 If money for the payment of principal or interest
remains unclaimed for two years, the Trustee and a Paying Agent shall pay the money back to the Company at their written request unless an abandoned property law designates another Person. After any such payment, the Holders entitled to the money
must look to the Company for payment as general creditors and the Trustee and a Paying Agent shall have no further liability with respect to such monies. 

	13.	Discharge and Defeasance 

 Subject to certain conditions, the
Company at any time may terminate some of or all of its obligations under the Securities and the Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to
redemption or maturity, as the case may be. 
  

	14.	Amendment; Waiver 

 Subject to certain exceptions set forth in the
Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at least a majority in aggregate principal amount of the outstanding Securities and (ii) any past default or compliance with any
provisions may be waived with the written consent of the Holders of at least a majority in principal amount of the outstanding Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Holder, the Company and
the Trustee may amend the Indenture or the Securities (i) to cure any ambiguity, omission, mistake, defect or inconsistency; (ii) to provide for the assumption by a Successor Company of the obligations of the Company under the Indenture
and the Securities; (iii) to provide for the assumption by a Successor Guarantor of the obligations of a Guarantor under the Indenture and its Guarantee; (iv) to provide for uncertificated Securities in addition to or in place of
certificated Securities (provided that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Securities are described in Section 163(f)(2)(B) of
the Code); (v) to add additional Guarantees with respect to the Securities; (vi) to make any change that would provide additional rights or benefits to the Holders or that does not adversely affect the legal rights of the Holders;
(vii) to make changes relating to the transfer and legending of the Securities; (viii) to secure the Securities; (ix) to add to the covenants of the Company for the benefit of the Holders or to surrender any right or power herein
conferred upon the Company or any Guarantor; (x) to make any change that does not adversely affect the legal rights of any Holder in any material respect; (xi) to comply with the requirements of the SEC in order to effect or maintain the
qualification of the Indenture under the TIA; (xii) to effect any provision of the Indenture; (xiii) to provide for the issuance of the Exchange Securities or Add-On Securities, as defined in the Indenture; (xiv) to evidence and
provide for the acceptance and appointment under the Indenture of a successor Trustee thereunder pursuant to the requirements thereof; or (xv) to conform the text of the Indenture, Guarantees or Securities to any provision of the section
entitled “Description of the Notes” in the Offering Memorandum. 
  

	15.	Defaults and Remedies 

 If an Event of Default occurs (other than an
Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company) and is continuing, the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities, in each case, by notice to the
Company, may declare the principal of, premium, if any, and accrued but unpaid interest on all the Securities to be due and payable provided, however, that so long as any Bank Indebtedness remains outstanding, no such acceleration
shall be effective until the earlier of (1) five Business Days after the giving of written 

 
notice to the Company and the Representative under the Credit Facilities and (2) the day on which any Bank Indebtedness is accelerated. Upon such a
declaration, such principal and interest will be due and payable immediately. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company occurs, the principal of, premium, if any, and interest on all
the Securities shall become immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Securities may
rescind any such acceleration with respect to the Securities and its consequences. 
 If an Event of Default occurs and is continuing, the Trustee shall be
under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee reasonable indemnity or security against any loss, liability or expense
and certain other conditions are complied with. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no Holder may pursue any remedy with respect to the Indenture or the Securities unless (i) such
Holder has previously given the Trustee notice that an Event of Default is continuing, (ii) the Holders of at least 25% in principal amount of the outstanding Securities have requested the Trustee in writing to pursue the remedy,
(iii) such Holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense, (iv) 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 (v) the Holders of a majority in principal amount of the outstanding Securities have not given the Trustee a direction inconsistent with such request within such 60-day period. Subject to certain restrictions, the
Holders of a majority in principal amount of the outstanding Securities are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on
the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal
liability. Prior to taking any action under the Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 
  

	16.	Trustee Dealings with the Company 

 Subject to certain limitations
imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may
otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 
  

	17.	No Recourse Against Others 

 No director, officer, employee,
manager, incorporator or holder of any Equity Interests (as defined in the Indenture) in the Company or any direct or indirect parent corporation, as such, shall have any liability for any obligations of the Company under the Securities, the
Indenture or for any claim based 

 
on, in respect of, or by reason of, such obligations or their creation. Each Holder of Securities by accepting a Security waives and releases all such
liability. 
  

	18.	Authentication 

 This Security shall not be valid until an
authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security. 
  

	19.	Abbreviations 

 Customary abbreviations may be used in the name of a
Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

  

	20.	Governing Law 

 THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW. 
  

	21.	CUSIP Numbers; ISINs; Common Codes 

 The Company has caused CUSIP
numbers, ISINs and Common Codes to be printed on the Securities and has directed the Trustee to use CUSIP numbers, ISINs and Common Codes in notices of redemption as a convenience to the Holders. No representation is made as to the accuracy of such
numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 
 The Company will furnish to any Holder of Securities upon written request and without charge to the Holder a copy of the Indenture which has in it the text of this Security.

 SECTION 2. Securities Subject to this Agreement. 
 (a) Transfer Restricted Securities. The securities entitled to the benefits of this Agreement are the Transfer Restricted Securities. 

(b) Holders of Transfer Restricted Securities. A Person is deemed to be a holder of Transfer Restricted Securities (each, a “Holder”)
whenever such Person owns Transfer Restricted Securities. 
 SECTION 3. Registered Exchange Offer. 
 (a) Unless the Exchange Offer shall not be permissible under applicable law or Commission policy, each of the Company and the Note Guarantors shall
(i) use its commercially reasonable efforts to cause the Exchange Offer Registration Statement to be filed with the Commission, (ii) use its commercially reasonable efforts to cause such Registration Statement to become effective in no
event later than 365 days after the Issue Date (or if such 365th day is not a Business Day, the next succeeding Business Day), (iii) in connection with the foregoing, (A) file all pre-effective amendments to such Registration Statement as
may be necessary in order to cause such Registration Statement to become effective, (B) file, if applicable, a post-effective amendment to such Registration Statement pursuant to Rule 430A under the Securities Act and (C) cause all
necessary filings in connection with the registration and qualification of the Exchange Securities to be made under the state securities or blue sky laws of such jurisdictions as are necessary to permit Consummation of the Exchange Offer and
(iv) upon the effectiveness of such Registration Statement, commence the Exchange Offer. The Exchange Offer Registration Statement shall be on the appropriate form permitting registration of the Exchange Securities to be offered in exchange for
the Transfer Restricted Securities and to permit resales of Initial Securities held by Broker-Dealers as contemplated by Section 3(c) hereof. 
 (b) The Company and the Note Guarantors shall cause the Exchange Offer Registration Statement to be effective continuously and shall keep the Exchange Offer open for a period of not less than the minimum period required under applicable
federal and state securities laws to Consummate the Exchange Offer; provided, however, that in no event shall such period be less than 30 days after the date notice of the Exchange Offer is mailed to the Holders. The Company shall
cause the Exchange Offer to comply with all applicable federal and state securities laws. The Company shall use its commercially reasonable efforts to cause the Exchange Offer to be Consummated on the earliest practicable date after the Exchange
Offer Registration Statement has become effective, but in no event later than 30 days after the date notice of the Exchange Offer is required to be mailed to the Holders (or if such 30th day is not a Business Day, the next succeeding Business Day).

 (c) The Company shall indicate in a “Plan of Distribution” section contained in the Prospectus forming a part of the Exchange
Offer Registration Statement that any Broker-Dealer who holds Initial Securities that are Transfer Restricted Securities and that were acquired for its own account as a result of market-making activities or other trading activities (other than

  

 4 

 
Transfer Restricted Securities acquired directly from the Company) may exchange such Initial Securities pursuant to the Exchange Offer; however, such
Broker-Dealer may be deemed to be an “underwriter” within the meaning of the Securities Act and must, therefore, deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of the Exchange Securities
received by such Broker-Dealer in the Exchange Offer, which prospectus delivery requirement may be satisfied by the delivery by such Broker-Dealer of the Prospectus contained in the Exchange Offer Registration Statement. Such “Plan of
Distribution” section shall also contain all other information with respect to such resales by Broker-Dealers that the Commission may require in order to permit such resales pursuant thereto, but such “Plan of Distribution” shall not
name any such Broker-Dealer or disclose the amount of Initial Securities held by any such Broker-Dealer except to the extent required by the Commission. 
 Each of the Company and the Note Guarantors shall use its commercially reasonable efforts to keep the Exchange Offer Registration Statement continuously effective, supplemented and amended as required by the
provisions of Section 6(c) hereof to the extent necessary to ensure that it is available for resales of Initial Securities acquired by Broker-Dealers for their own accounts as a result of market-making activities or other trading activities,
and to ensure that it conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, for a period ending on the earlier of (i) 180 days from the
date on which the Exchange Offer Registration Statement is declared effective and (ii) the date on which a Broker-Dealer is no longer required to deliver a prospectus in connection with market-making or other trading activities. 
 The Company shall provide sufficient copies of the latest version of such Prospectus to Broker-Dealers promptly upon request at any time during such
180-day (or shorter as provided in the foregoing sentence) period in order to facilitate such resales. 
 SECTION 4. Shelf
Registration. 
 (a) Shelf Registration. If with respect to the Initial
Notes: (i) the Company and the Note Guarantors are not permitted to consummate the Exchange Offer because the Exchange Offer is not permitted by applicable law or Commission policy, (ii) for any reason the Exchange Offer is not Consummated
within 30 days after the date notice of the Exchange Offer is required to be mailed to the Holders (or if such 30th day is not a Business Day, the next
succeeding Business Day), or (iii) with respect to any Holder of Transfer Restricted Securities (A) such Holder is prohibited by applicable law or Commission policy from participating in the Exchange Offer, or (B) such Holder may not
resell the Exchange Securities acquired by it in the Exchange Offer to the public without delivering a prospectus (other than by reason of such Holder’s status as an affiliate of the Company) and the Prospectus contained in the Exchange Offer
Registration Statement is not appropriate or available for such resales by such Holder, or (C) such Holder is a Broker-Dealer and holds Initial Securities acquired directly from the Company or one of its affiliates, then, upon such
Holder’s request prior to the 20th day following consummation of the Exchange Offer, the Company and the Note Guarantors shall, with respect to the
Initial Notes: 
 (x) cause to be filed a shelf registration statement pursuant to Rule 415 under the Securities
Act, which may be an amendment to the Exchange Offer Registration Statement (in either event, the “Shelf Registration Statement”) on or 

  

 5 

 
prior to 180 days after such filing obligation arises (or if such 180th day is not a Business Day, the next succeeding Business Day) (such date being the
“Shelf Filing Deadline”), which Shelf Registration Statement shall provide for resales of all Transfer Restricted Securities the Holders of which shall have provided the information required pursuant to Section 4(b) hereof; and

 (y) use their commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective by the
Commission, and in any event on or before the 365th day after the obligation to file such Shelf Registration Statement arises (or if such 365th day is not a Business Day, the next succeeding Business Day). 
 Each of the Company and the Note Guarantors shall use its commercially reasonable efforts to keep such Shelf Registration Statement continuously
effective, supplemented and amended as required by the provisions of Sections 6(b) and (c) hereof to the extent necessary to ensure that it is available for resales of Initial Securities by the Holders of Transfer Restricted Securities entitled
to the benefit of this Section 4(a), and to ensure that it conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, for a period of at least
two years following the effective date of such Shelf Registration Statement (or shorter period that will terminate when all the Initial Securities covered by such Shelf Registration Statement have been sold pursuant to such Shelf Registration
Statement). During the period during which the Company is required to maintain an effective Shelf Registration Statement pursuant to this Agreement, the Company will, prior to the expiration of that Shelf Registration Statement, file, and use its
commercially reasonable efforts to cause to be declared effective (unless it becomes effective automatically upon filing) within a period that avoids any interruption in the ability of Holders of Securities covered by the expiring Shelf Registration
Statement to make registered dispositions, a new registration statement relating to the Securities, which shall be deemed the “Shelf Registration Statement” for purposes of this Agreement. 
 (b) Provision by Holders of Certain Information in Connection with the Shelf Registration Statement. No Holder of Transfer Restricted Securities
may include any of its Transfer Restricted Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Company in writing, within 20 Business Days after receipt of a request therefor, such
information as the Company may reasonably request for use in connection with any Shelf Registration Statement or Prospectus or preliminary Prospectus included therein or amendment or supplement thereto or Free Writing Prospectus. Each Holder as to
which any Shelf Registration Statement is being effected agrees to furnish promptly to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Holder not materially
misleading. 
  

 6 

 SECTION 5. Additional Interest. If (i) unless the Exchange Offer shall not be permissible
under applicable law or Commission policy, the Exchange Offer Registration Statement has not been declared effective by the Commission (or become automatically effective) on or prior to 365 days after the Issue Date (the “Exchange Offer
Effectiveness Target Date”), (ii) in the event the Company and the Note Guarantors are required to file a Shelf Registration Statement pursuant to Section 4(a) hereof, the Shelf Registration Statement has not been declared effective
by the Commission (or become automatically effective) on or prior to 365 days after the obligation to file a Shelf Registration Statement arises (the “Shelf Registration Effectiveness Target Date” and, together with the Exchange Offer
Effectiveness Date, the “Effectiveness Target Date”), (iii) the Exchange Offer has not been Consummated within 30 Business Days after the Exchange Offer Effectiveness Target Date with respect to the Exchange Offer Registration
Statement, or (iv) any Registration Statement required by this Agreement is filed and declared effective but shall thereafter cease to be effective or fail to be usable for its intended purpose without being succeeded immediately by a
post-effective amendment to such Registration Statement that cures such failure and that is itself immediately declared or automatically effective (except in the case of a Registration Statement that ceases to be effective or usable as specifically
permitted by the last paragraph of Section 6 hereof) (each such event referred to in clauses (i) through (iv), a “Registration Default”), the Company and the Note Guarantors hereby agree that the interest rate borne by the
affected series of Transfer Restricted Securities shall be increased by 0.25% per annum during the 90-day period immediately following the occurrence of any Registration Default and shall increase by 0.25% per annum at the end of each
subsequent 90-day period, but in no event shall such increase exceed 1.00% per annum. Immediately upon the earliest of (y) the cure of all Registration Defaults relating to any particular Transfer Restricted Securities and (z) the
date on which such Transfer Restricted Security ceases to be a Transfer Restricted Security or otherwise becomes freely transferable by Holders other than affiliates of the Company without further registration under the Securities Act, the interest
rate borne by the relevant Transfer Restricted Securities will be reduced to the original interest rate borne by such Transfer Restricted Securities; provided, however, that, if after any such reduction in interest rate, a different
Registration Default occurs, the interest rate borne by the relevant Transfer Restricted Securities shall again be increased pursuant to the foregoing provisions. Any additional interest will be payable in the same form of payment selected by the
Issuer per the terms of the Indenture for the payment of interest with respect to the applicable interest period. 
 Notwithstanding the
foregoing, (i) the amount of Additional Interest payable shall not increase because more than one Registration Default has occurred and is pending, and (ii) Additional Interest shall be payable for Registration Defaults related to a
failure of the Company and the Note Guarantors to obtain a Shelf Registration Statement by the Shelf Registration Statement Effectiveness Target Date only to those Holders who sought to have their notes registered pursuant to the first paragraph of

 Section 4(a) hereof. 
 All obligations of
the Company and the Note Guarantors set forth in the first paragraph of this Section 5 that are outstanding with respect to any Transfer Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive
until such time as all such obligations with respect to such security shall have been satisfied in full. 
  

 7 

 SECTION 6. Registration Procedures. 
 (a) Exchange Offer Registration Statement. In connection with the Exchange Offer, the Company and the Note Guarantors shall comply with all of the
provisions of Section 6(c) hereof, shall use their commercially reasonable efforts to effect such exchange to permit the sale of Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution
thereof, and shall comply with all of the following provisions: 
 (i) As a condition to its participation in the Exchange Offer pursuant to
the terms of this Agreement, each Holder of Transfer Restricted Securities shall furnish, upon the request of the Company, prior to the Consummation thereof, a written representation to the Company (which may be contained in the letter of
transmittal contemplated by the Exchange Offer Registration Statement) to the effect that (A) it is not an affiliate of the Company, (B) it is not engaged in, and does not intend to engage in, and has no arrangement or understanding with
any Person to participate in, a distribution of the Exchange Securities to be issued in the Exchange Offer, (C) it is acquiring the Exchange Securities in its ordinary course of business and (D) it is not prohibited by any law or policy of
the Commission from participating in the Exchange Offer. In addition, all such Holders of Transfer Restricted Securities shall otherwise cooperate in the Company’s preparations for the Exchange Offer. Each Holder hereby acknowledges and agrees
that any Broker-Dealer and any such Holder using the Exchange Offer to participate in a distribution of the securities to be acquired in the Exchange Offer (1) could not under Commission policy as in effect on the date of this Agreement rely on
the position of the Commission enunciated in Morgan Stanley and Co., Inc. (available June 5, 1991) and Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted in the Commission’s letter to
Shearman & Sterling dated July 2, 1993, and similar no-action letters (which may include any no-action letter obtained pursuant to clause (i) above), and (2) must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with a secondary resale transaction and that such a secondary resale transaction should be covered by an effective registration statement containing the selling security holder information required by
Item 507 or 508, as applicable, of Regulation S-K if the resales are of Exchange Securities obtained by such Holder in exchange for Initial Securities acquired by such Holder directly from the Company. 
 (b) Shelf Registration Statement. In connection with the Shelf Registration Statement, each of the Company and the Note Guarantors shall comply
with all the provisions of Section 6(c) hereof and shall use its commercially reasonable efforts to effect such registration (unless automatically declared effective) to permit the sale of the Transfer Restricted Securities being sold in
accordance with the intended method or methods of distribution thereof, and pursuant thereto each of the Company and the Note Guarantors will as expeditiously as is commercially reasonable prepare and file with the Commission a Registration
Statement relating to the registration on any appropriate form under the Securities Act, which form shall be available for the sale of the Transfer Restricted Securities in accordance with the intended method or methods of distribution thereof.

 (c) General Provisions. In connection with any Registration Statement and any Prospectus required by this Agreement to permit the
sale or resale of Transfer Restricted Securities and any Free Writing Prospectus (including, without limitation, any Registration Statement and the related Prospectus required to permit resales of Initial Securities by Broker- 

  

 8 

 
Dealers and any Free Writing Prospectus related thereto), each of the Company and the Note Guarantors shall: 
 (i) use its commercially reasonable efforts to keep such Registration Statement continuously effective during the period required by this Agreement and
provide all requisite financial statements (including, if required by the Securities Act or any regulation thereunder, financial statements of the Note Guarantors for the period specified in Section 3 or 4 hereof, as applicable); upon the
occurrence of any event that would cause any such Registration Statement or the Prospectus contained therein (A) to contain a material misstatement or omission or (B) not to be effective and usable for resale of Transfer Restricted
Securities during the period required by this Agreement, the Company shall file promptly an appropriate amendment to such Registration Statement, in the case of clause (A), correcting any such misstatement or omission, and, in the case of either
clause (A) or (B), use its commercially reasonable efforts to cause such amendment to be declared effective (unless automatically declared effective) and such Registration Statement and the related Prospectus to become usable for their intended
purpose(s) as soon as practicable thereafter; 
 (ii) prepare and file with the Commission such amendments and post-effective amendments to
the applicable Registration Statement as may be necessary to keep the Registration Statement effective for the applicable period set forth in Section 3 or 4 hereof, as applicable, or such shorter period as will terminate when all Transfer
Restricted Securities covered by such Registration Statement have been sold; cause the Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act, and to
comply fully with the applicable provisions of Rules 424 and 430A under the Securities Act in a timely manner; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration
Statement during the applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in such Registration Statement or supplement to the Prospectus; 
 (iii) advise the underwriter(s), if any, and selling Holders promptly and, if requested by such Persons, to confirm such advice in writing, (A) when
the Prospectus, any Prospectus supplement, any post-effective amendment or any Free Writing Prospectus has been filed, and, with respect to any Registration Statement or any post-effective amendment thereto, when the same has become effective,
(B) of any request by the Commission for amendments to the Registration Statement or amendments or supplements to the Prospectus or for additional information relating thereto, (C) of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement under the Securities Act, of the suspension by any state securities commission of the qualification of the Transfer Restricted Securities for offering or sale in any jurisdiction, or the
initiation of any proceeding for any of the preceding purposes, of the issuance by the Commission of a notification of objection to the use of the form on which the Registration Statement has been filed, or of the happening of any event that causes
the Company to become an “ineligible issuer,” as defined in Commission Rule 405 and (D) of the existence of any fact or the happening of any event that makes any statement of a material fact made in the Registration Statement, the
Prospectus, any amendment or supplement thereto or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the Registration Statement or the Prospectus in order to make the statements

  

 9

thereto;

accuracy, completeness or fairness of such statements; and that such counsel advises that, on the basis of the foregoing, no facts came to such counsel’s attention that caused such counsel to believe that the applicable Registration Statement,
(A) at the date of the opinion and at the time such Registration Statement or any post-effective amendment thereto became effective, (B) at the applicable time identified by such Holders or managing underwriters, and (C) in the case
of the Exchange Offer Registration Statement, as of the date of Consummation, in the case of (A), (B) and (C) contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary
to make the statements therein not misleading, or that the Prospectus contained in such Registration Statement as of its date and, in the case of the opinion dated the date of Consummation of the Exchange Offer, as of the date of Consummation,
contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein not misleading. Without limiting the foregoing, such counsel may state further that such counsel assumes no
responsibility for, and has not independently verified, the accuracy, completeness or fairness of the financial statements, notes and schedules and other financial data included in any Registration Statement contemplated by this Agreement or the
related Prospectus; and 
 (3) a customary comfort letter from the Company’s independent accountants, in the customary

Restricted Securities under the state securities or blue sky laws of such jurisdictions as the selling Holders or underwriter(s), if any, may request and do any and all other acts or things necessary or advisable to enable the disposition in such
jurisdictions of the Transfer Restricted Securities covered by the Shelf Registration Statement; provided, however, that none of the Company or the Note Guarantors shall be required to register or qualify as a foreign corporation where
it is not then so qualified or to take any action that would subject it to the service of process in suits or to taxation, other than as to matters and transactions relating to the Registration Statement, in any jurisdiction where it is not then so
subject; 
 (xiii) issue, upon the request of any Holder of Initial Securities covered by the Shelf Registration Statement, Exchange

the name of such Holder or in the name of the purchaser(s) of such Securities, as the case may be; in return, the Initial Securities held by such Holder shall be surrendered to the Company for cancellation; 
 (xiv) subject to the terms of the Indenture, cooperate with the selling Holders and the underwriter(s), if any, to facilitate the timely preparation and
delivery of certificates representing Transfer Restricted Securities to be sold and not bearing any restrictive legends; and enable such Transfer Restricted Securities to be in such denominations and registered in such names as the Holders or the

 (xvi) if any fact or event contemplated by Section 6(c)(iii)(D) hereof shall exist or have occurred, prepare a supplement or post-effective
amendment to the Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Transfer Restricted

statements therein not misleading; 
 (xvii) provide a CUSIP number for all Securities not later than the effective date of the Registration
Statement covering such Securities and provide the Trustee under the applicable Indenture with printed certificates for such Securities which are in a form eligible for deposit with the Depository Trust Company and take all other action necessary to

of the NASD; 
 (xix) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the

Company’s first fiscal quarter commencing after the effective date of the Registration Statement; 
 (xx) cause the Indenture to be

be required to effect such changes and all other forms and documents required to be filed with the Commission to enable such Indenture to be so qualified in a timely manner; and 
 (xxi) maintain the listing of all Securities covered by the Registration Statement on The
PORTALSM Market. 
 Each Holder agrees
by acquisition of a Transfer Restricted Security that, upon receipt of any notice from the Company of the existence of any fact of the kind described in Section 6(c)(iii)(D) hereof, such Holder will forthwith discontinue disposition of Transfer
Restricted Securities pursuant to the applicable Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 6(c)(xvi) hereof, or until it is advised in writing (the
“Advice”) by the Company that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus. If so directed by the Company, each Holder will
deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Transfer Restricted Securities that was current at the time of receipt of such
notice. In the event the Company shall give any such notice, the time period regarding the effectiveness of such Registration Statement set forth 

  

 14

date of the giving of such notice pursuant to Section 6(c)(iii)(D) hereof to and including the date when each selling Holder covered by such Registration Statement shall have received the copies of the supplemented or amended Prospectus
contemplated by Section 6(c)(xvi) hereof or shall have received the Advice; provided that there shall not be more than 75 days of Delay Periods during any 12-month period; provided further, however, that (except as provided
in Section 5(iv) hereof) no such extension shall be taken into account in determining whether Additional Interest is due pursuant to Section 5 hereof or the amount of such Additional Interest, it being agreed that the Company’s option
to suspend use of a Registration Statement pursuant to this paragraph shall be treated as a Registration Default for purposes of Section 5 hereof. 
 SECTION 7. Registration Expenses. 
 (a) All expenses incident to the Company’s and the
Guarantor’s performance of or compliance with this Agreement will be borne by the Company and the Note Guarantors, jointly and severally, regardless of whether a Registration Statement becomes effective, including, without limitation:
(i) all registration and filing fees and expenses (including filings made by any Initial Purchaser or Holder with the NASD (and, if applicable, the fees and expenses of any “qualified independent underwriter,” and one counsel to such

fees and expenses of any Person, including special experts, retained by the Company or the Note Guarantors. 
 (b) In connection with a Shelf

 15 

 SECTION 8. Indemnification. 
 (a) The Company and the Note Guarantors, jointly and severally, agree to indemnify and hold harmless (i) the Initial Purchasers, (ii) each
Holder and (iii) each Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) any Holder or Initial Purchaser (any of the Persons referred to in this clause
(ii) being hereinafter referred to as a “controlling person”) and (iv) the respective officers, directors, partners, employees, representatives and agents of any Holder, Initial Purchaser or any controlling person (any Person
referred to in clause (i), (ii), (iii) or (iv) may hereinafter be referred to as an “Indemnified Holder”), to the fullest extent lawful, from and against any and all losses, claims, damages, liabilities, judgments, actions and
expenses (including, without limitation, and as incurred, reimbursement of all reasonable costs of investigating, preparing, pursuing, settling, compromising, paying or defending any claim or action, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, including the reasonable fees and expenses of counsel to any Indemnified Holder), joint or several, directly or indirectly caused by, related to, based upon, arising out of or in connection with
any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement, Prospectus (or any amendment or supplement thereto) or Free Writing Prospectus, in all cases including any documents incorporated by
reference therein, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or expenses
are caused by an untrue statement or omission or alleged untrue statement or omission that is made in reliance upon and in conformity with information relating to any of the Holders furnished in writing to the Company by any of the Holders expressly
for use therein. This indemnity agreement shall be in addition to any liability that the Company or any of the Note Guarantors may otherwise have. 
 In case any action or proceeding (including any governmental or regulatory investigation or proceeding) shall be brought or asserted against any of the Indemnified Holders with respect to which indemnity may be sought against the Company or
the Note Guarantors, such Indemnified Holder (or the Indemnified Holder controlled by such controlling person) shall promptly notify the Company and the Note Guarantors in writing; provided, however, that the failure to give such
notice shall not relieve any of the Company or the Note Guarantors of its obligations pursuant to this Agreement. Such Indemnified Holder shall have the right to employ its own counsel in any such action and the fees and expenses of such counsel
shall be paid, as incurred, by the Company and the Note Guarantors (regardless of whether it is ultimately determined that an Indemnified Holder is not entitled to indemnification hereunder). The Company and the Note Guarantors shall not, in
connection with any one such action or proceeding or separate but substantially similar or related actions or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and
expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for such Indemnified Holders, which firm shall be designated by the Holders. The Company and the Note Guarantors shall be liable for any settlement
of any such action or proceeding effected with the Company’s and the Note Guarantors’ prior written consent, which consent shall not be withheld unreasonably, and each of the Company and the Note Guarantors agrees to indemnify and hold
harmless any Indemnified Holder from and against any loss, claim, damage, liability or expense by reason of any settlement of any action 

  

 16 

 
effected with the written consent of the Company and the Note Guarantors. The Company and the Note Guarantors shall not, without the prior written consent of
each Indemnified Holder, settle or compromise or consent to the entry of judgment in or otherwise seek to terminate any pending or threatened action, claim, litigation or proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not any Indemnified Holder is a party thereto), unless such settlement, compromise, consent or termination includes an unconditional release of each Indemnified Holder from all liability arising out of such action, claim,
litigation or proceeding and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Indemnified Holder. 
 (b) Each Holder of Transfer Restricted Securities agrees, severally and not jointly, to indemnify and hold harmless the Company, the Note Guarantors, the Initial Purchasers and the other Holders of Transfer Restricted
Securities and their respective directors, officers of the Company and the Note Guarantors who sign a Registration Statement, and any Person controlling (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act) the Company, any of the Note Guarantors, the Initial Purchasers or the other Holders of Transferred Restricted Securities and the respective officers, directors, partners, employees, representatives and agents of each such Person, to the same
extent as the foregoing indemnity from the Company and the Note Guarantors to each of the Indemnified Holders, but only with respect to claims and actions based on the statements or omissions, or alleged untrue statements or omissions relating to
such Holder furnished in writing by such Holder expressly for use in any Registration Statement; provided, however, that no such Holder shall be liable for any claims hereunder in excess of the amount of net proceeds received by such Holder
from the sale of Registrable Securities pursuant to any such Registration Statement. In case any action or proceeding shall be brought against the Company, the Note Guarantors, the Initial Purchasers and the other Holders of Transfer Restricted
Securities or their respective directors or officers or any such controlling person in respect of which indemnity may be sought against a Holder of Transfer Restricted Securities, such Holder shall have the rights and duties given the Company the
Note Guarantors, the Initial Purchasers and the other Holders of Transfer Restricted Securities, and the Company, the Note Guarantors, the Initial Purchasers, the other Holders of Transfer Restricted Securities, their respective directors and
officers and such controlling person shall have the rights and duties given to each Holder by the preceding paragraph. 
 (c) If the
indemnification provided for in this Section 8 is unavailable to an indemnified party under Section 8(a) or (b) hereof (other than by reason of exceptions provided in those Sections) in respect of any losses, claims, damages,
liabilities, judgments, actions or expenses referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such
losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative benefits received by the Company and the Note Guarantors, on the one hand, and the Holders and the Initial Purchasers, on the other hand,
from the Initial Placement (which in the case of the Company and the Note Guarantors shall be deemed to be equal to the total gross proceeds to the Company and the Note Guarantors from the Initial Placement), the amount of Additional Interest which
did not become payable as a result of the filing of the Registration Statement resulting in such losses, claims, damages, liabilities, judgments, actions or expenses, and such Registration Statement, or if such allocation is not permitted by
applicable law, the relative fault of the Company and the Note Guarantors, on the 

  

 17 

 
one hand, and the Holders and the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of the Company and the Note Guarantors, on the one hand, and of the Indemnified Holder on the other shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or any of the Note Guarantors, on the one hand, or
the Indemnified Holders, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses,
claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in the second paragraph of Section 8(a) hereof, any legal or other fees or expenses reasonably incurred by such party
in connection with investigating or defending any action or claim. 
 The Company, the Note Guarantors, the Initial Purchasers and each
Holder of Transfer Restricted Securities agree that it would not be just and equitable if contribution pursuant to this Section 8(c) were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by
any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities
or expenses referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or
defending any such action or claim. Notwithstanding the provisions of this Section 8, none of the Holders (and its related Indemnified Holders) shall be required to contribute, in the aggregate, any amount in excess of the amount by which the
total discount received by such Holder with respect to the Initial Securities exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged
omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The Holders’
obligations to contribute pursuant to this Section 8(c) are several in proportion to the respective principal amount of Initial Securities held by each of the Holders hereunder and not joint. 
 SECTION 9. Rule 144A. Each of the Company and the Note Guarantors hereby agrees with each Holder, for so long as any Transfer Restricted
Securities remain outstanding, to make available to any Holder or beneficial owner of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such Transfer Restricted Securities from such Holder or
beneficial owner, the information required by Rule 144A(d)(4) under the Securities Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A under the Securities Act. 
  

 18 

 SECTION 10. Participation in Underwritten Registrations. No Holder may participate in any
Underwritten Registration hereunder unless such Holder (a) agrees to sell such Holder’s Transfer Restricted Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such
arrangements and (b) completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements. 
 SECTION 11. Selection of Underwriters. The Holders of Transfer Restricted Securities covered by the Shelf Registration Statement who desire to do
so may sell such Transfer Restricted Securities in an Underwritten Offering. In any such Underwritten Offering, the investment banker(s) and managing underwriter(s) that will administer such offering will be selected by the Holders of a majority in
aggregate principal amount of the Transfer Restricted Securities included in such offering; provided, however, that such investment banker(s) and managing underwriter(s) must be reasonably satisfactory to the Company. 
 SECTION 12. Miscellaneous. 
 (a)
Remedies. Each of the Company and the Note Guarantors hereby agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and hereby agrees to waive the
defense in any action for specific performance that a remedy at law would be adequate. 
 (b) No Inconsistent Agreements. Each of the
Company and the Note Guarantors will not on or after the date of this Agreement enter into any agreement with respect to its securities that conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict
with the rights granted to the holders of the Company’s or any of the Note Guarantors’ securities under any agreement in effect on the date hereof. 
 (c) Adjustments Affecting the Securities. The Company will not effect any change, or permit any change to occur, in each case, with respect to the terms of the Securities that would materially and adversely
affect the ability of the Holders to Consummate any Exchange Offer. 
 (d) Amendments and Waivers. The provisions of this Agreement
may not be amended, modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given unless the Company has (i) in the case of Section 5 hereof and this Section 12(d)(i), obtained the
written consent of Holders of all outstanding Transfer Restricted Securities and (ii) in the case of all other provisions hereof, obtained the written consent of Holders of a majority of the outstanding principal amount of Transfer Restricted
Securities (excluding any Transfer Restricted Securities held by the Company or their Affiliates). Notwithstanding the foregoing, a waiver or consent to departure from the provisions hereof that relates exclusively to the rights of Holders whose
securities are being tendered pursuant to the Exchange Offer and that does not affect directly or indirectly the rights of other Holders whose securities are not being tendered pursuant to such Exchange Offer may be given by the Holders of a
majority of the outstanding principal amount of Transfer Restricted Securities being tendered or registered; provided, however, that, with respect to any matter that directly or indirectly affects the rights of any Initial Purchaser
hereunder, the Company shall obtain the 

  

 19 

 
written consent of each such Initial Purchaser with respect to which such amendment, qualification, supplement, waiver, consent or departure is to be
effective.
