upon which the Notes are, and are to be, authorized and delivered. All terms used in this Note that are defined in the Indenture shall have the meaning assigned to them in the Indenture. 

 

	 	1.	Method of Payment 


Holders must surrender Notes to a Paying Agent to collect payment. The Co-Issuers shall make payment in money of the United States of
America that at the time of payment is legal tender for payment of public and private debts. The Co-Issuers may make payment by check payable in such money. 
  

	 	2.	Paying Agent, Security Registrar and Conversion Agent 

 Initially, the Trustee will act as Paying Agent, Security Registrar and Conversion Agent. The Co-Issuers may appoint and change any Paying Agent, Security Registrar or co-registrar or Conversion
Agent upon written notice thereto. Either Co-Issuer or any Subsidiary or Affiliate of any of them may act as Paying Agent, Security Registrar or co-registrar. 
  

	 	3.	Indenture 

 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. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a
statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control. 

 

	 	4.	Sinking Fund and Redemption 

 The Notes are not subject to the provisions of Articles Eleven or Twelve of the Base Indenture. 
  

	 	5.	Repurchase of Notes at the Option of Holders 

 If there shall occur a Fundamental Change at any time prior to the Maturity Date, then each Holder shall have the right, at such Holder’s option, to require the Co-Issuers to repurchase for cash any
or all of such Holder’s Notes in accordance with the terms of the Indenture. 
  

	 	6.	Conversion 

 Subject to
and upon compliance with the provisions of the Indenture, the Holder hereof has the right, at its option, prior to 5:00 p.m. (New York City time) on the Business Day immediately preceding the Maturity Date, to convert any Notes or portion
thereof that is equal to the Initial Principal Amount or an integral multiple thereof, into shares of Common Stock, at the applicable Conversion Price specified in the Indenture, as adjusted from time to time as provided in the Indenture.

  

	 	7.	Denominations, Transfer, Exchange 

 The Notes are in registered form without coupons, in minimum denominations of $25 and integral multiples of $25 in excess thereof. A Holder may register the transfer or exchange of Notes in
accordance with the Indenture. The Note Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. 







	 	8.	Persons Deemed Owners 


The registered Holder of this Note may be treated as the owner of it for all purposes. 

 

	 	9.	Unclaimed Money

to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Co-Issuers upon written request any money held by them for the payment of principal or interest and any shares of Common Stock or other property due in
respect of converted Notes that remains unclaimed for two years, and, thereafter, Holders entitled to the money or securities must look to the Co-Issuers for payment as general creditors. 

 

	 	10.	Amendment, Supplement, Waiver 

 Subject to certain exceptions, the Indenture, the Security Documents, the Intercreditor Agreement or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in
aggregate Initial Principal Amount of the Outstanding Notes, and any existing Default or compliance with any provision may be waived with the consent of the Holders of a majority in aggregate Initial Principal Amount of the Outstanding
Notes. Without notice to or the consent of any Holder, the parties thereto may amend or supplement the Indenture, the Security Documents, the Intercreditor Agreement or the Notes to, among other things, cure any ambiguity, defect or
inconsistency and make any change that does not adversely affect the rights of any Holder. 
  

	 	11.	Restrictive Covenants 


The Indenture contains certain covenants, including, without limitation, covenants with respect to the Liens and the
Collateral. Within 120 days after the end of each fiscal year, the Co-Issuers must report to the Trustee on compliance with such limitations in the manner set forth in the Indenture. 

 

	 	12.	Remedies for Events of Default 

 If an Event of Default, as defined in the Indenture, occurs and is continuing, the Trustee or the Holders of at least 30% in Initial Principal Amount of the Outstanding Notes may declare all the Notes to
be immediately due and payable. If a bankruptcy or insolvency default with respect to either Co-Issuer or any of its Significant Subsidiaries occurs and is continuing, the Notes automatically become immediately due and payable. Holders may
not enforce the Indenture, the Security Documents, the Intercreditor Agreement or the Notes except as provided in the Indenture. The Trustee and the Collateral Agent may require indemnity reasonably satisfactory to it before it enforces the
Indenture or the Notes. Subject to certain limitations, Holders of at least a majority in aggregate Initial Principal Amount of the Outstanding Notes may direct the Trustee in its exercise of any trust or power. 

 

	 	13.	Trustee Dealings with the Co-Issuers 

 The Trustee or the Collateral Agent under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may make loans to, accept deposits from, perform services
for, and otherwise deal with, the Co-Issuers and their Affiliates as if it were not the Trustee or the Collateral Agent. 
  

	 	14.	Successor Persons 

 When a
successor Person or other entity assumes all the obligations of its predecessor under the Notes and the Indenture, the predecessor Person shall be released from those obligations. 

 

	 	15.	Guarantees 

 The
Co-Issuers’ obligations under the Notes are fully, irrevocably and unconditionally guaranteed on a senior secured basis, to the extent set forth in the Indenture, by each of the Guarantors.
