ARTICLE I 

DEFINITIONS 

Section 1.01. Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them
in the Indenture. 
 ARTICLE II 

GUARANTEES 

Section 2.01. The Guarantees. Subject to the provisions of this Article, the Guaranteeing Subsidiary hereby irrevocably and
unconditionally guarantees, jointly and severally, on a senior secured basis, the full and punctual payment (whether at maturity, upon any redemption, by declaration or acceleration, or otherwise) of the principal of, premium, if any, and interest
on, and all other amounts payable under the Notes, and the full and punctual payment of all other amounts payable by the Company under the Indenture. Upon failure by the Company to pay punctually any such amount, the Guaranteeing Subsidiary shall
forthwith pay the amount not so paid at the place and in the manner specified in the Indenture. The Guaranteeing Subsidiary further agrees to pay any and all expenses (including reasonable counsel fees and expenses) incurred by the Trustee or the
Agent in enforcing or exercising any rights under this Note Guarantee. 







 Section 2.02. Guarantee Unconditional. (a) The obligations of the Guaranteeing
Subsidiary hereunder are direct, unsubordinated, unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by: 

(1) any extension, renewal, settlement, compromise, failure to enforce, waiver or release in respect of any obligation of
the Company under the Indenture, this Supplemental Indenture or under the Notes, by operation of law or otherwise; 

(2) any rescission, waiver or, subject to Section 12.03 of the Indenture, any modification or amendment of or
supplement to, the Indenture or the Notes; 
 (3) the occurrence or notice of any default or event of default under the
Indenture or under any other agreement; 
 (4) any change in the corporate existence, structure or ownership of the
Company, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Company or their assets or any resulting release or discharge of any obligation of the Company contained under the Indenture or under the Notes; 

(5) the existence of any claim, set-off or other rights which the Guaranteeing
Subsidiary may have at any time against the Company, the Trustee or any other Person, whether in connection with the Indenture or any unrelated transactions, provided that nothing herein prevents the assertion of any such claim by separate suit or
compulsory counterclaim; 
 (6) any invalidity or unenforceability relating to or against the Company for any reason of the
Indenture or any Note, or any provision of applicable law or regulation purporting to prohibit the payment by the Company of the principal of or interest on the Notes or any other amount payable by the Company under the Indenture; or 

(7) any other act or omission to act or delay of any kind by the Company, the Trustee or any other Person or any other
circumstance whatsoever which might, but for the provisions of this paragraph, constitute a legal or equitable discharge of or defense to such Guaranteeing Subsidiary’s obligations hereunder. 

Section 2.03. Discharge; Reinstatement. The Guaranteeing Subsidiary’s obligations hereunder will remain in full force and
effect until the principal of, premium, if any, and interest on the Notes and all other amounts payable by the Company under the Indenture have been paid in full. If at any time any payment of the principal of, premium, if any, or interest on any
Note or any other amount payable by the Company under the Indenture is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Company or otherwise, the Guaranteeing Subsidiary’s obligations
hereunder with respect to such payment will be reinstated as though such payment had been due but not made at such time.

 Section 2.04. Waiver by the Guaranteeing Subsidiary. The Guaranteeing Subsidiary
irrevocably waives acceptance hereof, presentment, demand, protest and any notice not provided for under the Indenture or herein, as well as any requirement that at any time any action be taken by any Person against the Company or any other Person.

 Section 2.05. Subrogation and Contribution. Upon making any payment with respect to any obligation of the Company under this
Article, the Guaranteeing Subsidiary will be subrogated to the rights of the payee against the Company with respect to such obligation, provided that the Guaranteeing Subsidiary may not enforce either any right of subrogation, or any right to
receive payment in the nature of contribution, or otherwise, from any other Guarantor (including any Guaranteeing Subsidiary), with respect to such payment so long as any amount payable by the Company hereunder or under the Notes remains unpaid.

 Section 2.06. Stay of Acceleration. If acceleration of the time for payment of any amount payable by the Company under the
Indenture or the Notes is stayed upon the insolvency, bankruptcy or reorganization of the Company, all such amounts otherwise subject to acceleration under the terms of the Indenture are nonetheless payable by the Guaranteeing Subsidiary hereunder
forthwith on demand by the Trustee or the Holders. 
 Section 2.07. Limitation on Amount of Guarantee. Notwithstanding anything
to the contrary in this Article, the Guaranteeing Subsidiary, 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 Guaranteeing Subsidiary not constitute a
fraudulent conveyance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law. To effectuate that intention, the Trustee, the Holders and the Guaranteeing Subsidiary hereby
irrevocably agree that the obligations of the Guaranteeing Subsidiary under its Note Guarantee are limited to the maximum amount that would not render the Guaranteeing Subsidiary’s obligations subject to avoidance under applicable fraudulent
conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law. 
 Section 2.08. Execution and
Delivery of Guaranty. The execution by the Guaranteeing Subsidiary of this Supplemental Indenture evidences the Note Guarantee of the Guaranteeing Subsidiary, whether or not the person signing as an officer of the Guaranteeing Subsidiary still
holds that office at the time of authentication of any Note. The delivery of any Note by the Trustee after authentication constitutes due delivery of the Note Guarantee set forth in this Supplemental Indenture on behalf of the Guaranteeing
Subsidiary. 
 ARTICLE III

under or upon any obligation, covenant or agreement contained in the Indenture or in this Note Guarantee, or because of any indebtedness evidenced thereby, shall be had against any incorporator, as such or against any past, present or future
stockholder, officer or director, as such, of a Company or the Guaranteeing Subsidiary, or of any successor, either directly or through a Company, Guaranteeing Subsidiary or any successor, under any rule of law, statute or constitutional provision
