 WHEREAS, on the date hereof, each Successor Guarantor has executed and delivered a counterpart to the Registration Rights Agreement, evidencing its assumption of all obligations of its Predecessor
Guarantor under the Registration Rights Agreement; 
 WHEREAS, the Indenture provides that under certain circumstances each of
the Successor Guarantors shall execute and deliver to the Trustee a supplemental indenture pursuant to which each such Successor Guarantor shall unconditionally assume all of the obligations of its Predecessor Guarantor under the Indenture and such

 2. AGREEMENT TO ASSUME
OBLIGATIONS. Such Successor Guarantor hereby agrees to unconditionally assume all of the obligations of its Predecessor Guarantors under such Predecessor Guarantor’s Note Guarantee, the Indenture and the Registration Rights
Agreement. 
 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, this Indenture, 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

RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY. 
 5. COUNTERPARTS. The parties
may sign any number of copies of this Sixth Supplemental Indenture. Each signed copy (which may be provided via facsimile or other electronic transmission) 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. 
 7. THE TRUSTEE. The Trustee shall not be responsible in any
manner whatsoever for or in respect of the validity or sufficiency of this Sixth Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Successor Guarantors, the other Guarantors
