the Trustee or any other Secured Party to assert any claim or demand or to exercise or enforce any right or remedy under the provisions of the Indenture or otherwise; (ii) any rescission, waiver, amendment or modification of, or any release from any
of the terms or provisions of, the Indenture or any other agreement, including with respect to any other Notes Guarantor under this Secured Notes Guarantee; (iii) the failure to perfect any security interest in, or the exchange, substitution,
release or any impairment of, any security held by the Trustee or any other Secured Party for the Guaranteed Obligations; (iv) any default, failure or delay, willful or otherwise, in the performance of the Guaranteed Obligations; (v) any other act
or omission that may or might in any manner or to any extent vary the risk of any Notes Guarantor or otherwise operate as a discharge of any Notes Guarantor as a matter of law or equity (other than the payment in full in cash in immediately
available funds of all the Guaranteed Obligations); (vi) any illegality, lack of validity or enforceability of any Guaranteed Obligation; (vii) 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 its assets or any resulting release or discharge of any Guaranteed Obligation (other than the payment in full in cash in immediately available funds of all the
Guaranteed Obligations); (viii) the existence of any claim, set-off or other rights that such Notes Guarantor may have at any time against the Company, the Trustee, or any other corporation or Person, whether in connection herewith or any unrelated
transactions; provided that nothing herein will prevent the assertion of any such claim by separate suit or compulsory counterclaim; and (ix) any other circumstance (including, without limitation, any statute of limitations) or any
existence of or reliance on any representation by the Trustee that might otherwise constitute a defense to, or a legal or equitable discharge of, the Company or any other guarantor or surety (other than defense of payment or performance). Each
Notes Guarantor expressly authorizes the Secured Parties (or the Trustee on behalf of the Secured Parties) to take and hold security for the payment and performance of the Guaranteed Obligations, to exchange, waive or release any or all such
security (with or without consideration), to enforce or apply such security and direct the order and manner of any sale thereof in their sole discretion or to release or substitute any one or more other guarantors or obligors upon or in respect of
the Guaranteed Obligations, all without affecting the obligations of any Notes Guarantor hereunder. To the 

  
 Seventh Supplemental
Indenture

fullest extent permitted by applicable law, each Notes Guarantor waives any defense based on or arising out of any defense of any other Notes Guarantor or the unenforceability of the Guaranteed
Obligations or any part thereof from any cause, or the cessation from any cause of the liability of any other Notes Guarantor, other than the payment in full in cash in immediately available funds of all the Guaranteed Obligations. The Trustee
and the other Secured Parties may, at their election, foreclose on any security held by one or more of them by one or more judicial or nonjudicial sales, accept an assignment of any such security in lieu of foreclosure, compromise or adjust any part
of the Guaranteed Obligations, make any other accommodation with the Company or exercise any other right or remedy available to them against the Company, without affecting or impairing in any way the liability of any Notes Guarantor hereunder except
to the extent the Guaranteed Obligations have been paid in full in cash in immediately available funds. To the fullest extent permitted by applicable law, each Notes Guarantor waives any defense arising out of any such election even though such
election operates, pursuant to applicable law, to impair or to extinguish any right of reimbursement or subrogation or other right or remedy of such Notes Guarantor against any other Notes Guarantor, as the case may be, or any security. 

Section 2.4 Reinstatement. 

Notwithstanding the provisions of Section 2.8, each Notes Guarantor agrees that its Secured Notes Guarantee shall continue to be
effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of any Guaranteed Obligation is rescinded or must otherwise be restored or returned by the Trustee or any other Secured Party upon the insolvency,
bankruptcy, dissolution, liquidation or reorganization of the Company, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Company or any substantial part of its property, or
otherwise, all as though such payment had not been made. 
 Section 2.5 Agreement To Pay; Subrogation. 

In furtherance of the foregoing and not in limitation of any other right that the Trustee or any other Secured Party has at law or in equity
against any Notes Guarantor by virtue hereof, upon the failure of the Company to pay any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, after notice of prepayment or otherwise, each Notes Guarantor
hereby promises to and will forthwith pay, or cause to be paid, to the Trustee for distribution to the applicable Secured Party in cash in immediately available funds the amount of such unpaid Guaranteed Obligation. Upon payment by any Notes
Guarantor of any sums to the First Lien Collateral Agent as provided above, all rights of such Notes Guarantor against the Company arising as a result thereof by way of right of subrogation, contribution, reimbursement, indemnity or otherwise shall
in all respects be subject to Section 7.06 of the Indenture. 
 Section 2.6 Information. 

Each Notes Guarantor assumes all responsibility for being and keeping itself informed of the Company’s financial condition and assets,
and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks 

  
 Seventh Supplemental
Indenture

that such Notes Guarantor assumes and incurs hereunder, and agrees that neither the Trustee nor any other Secured Party will have any duty to advise such Notes Guarantor of information known to
it or any of them regarding such circumstances or risks. 
 Section 2.7 Maximum Liability. 

Each Notes Guarantor, and by its acceptance of each Secured Notes Guarantee, the Trustee and each Secured Party hereby confirms that it is the
intention of all such Persons that its Secured Notes Guarantee and its Guaranteed Obligations not constitute a fraudulent transfer or conveyance for purposes of the U.S. Bankruptcy Code or any other federal, state or foreign bankruptcy, insolvency,
receivership or similar law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or state law to the extent applicable to this Secured Notes Guarantee and the Guaranteed Obligations of each
Notes Guarantor hereunder. To effectuate the foregoing intention, the First Lien Collateral Agent, the Secured Parties and the Notes Guarantors hereby irrevocably agree that the Guaranteed Obligations of each Notes Guarantor under this Secured
Notes Guarantee at any time shall be limited to the maximum amount as will result in the Guaranteed Obligations of such Notes Guarantor under this Secured Notes Guarantee not constituting a fraudulent transfer or conveyance. 

Section 2.8 Termination and Release. 

(1) A Notes Guarantor shall automatically be released from its obligations hereunder in accordance with Article IV hereof. 

(2) A Secured Notes Guarantee as to any Notes Guarantor shall terminate and be of no further force or effect and such Notes Guarantor shall be
deemed to be released from all obligations under this Article II upon: 
 (a) the sale, disposition, exchange or other transfer
(including through merger, consolidation, amalgamation or otherwise) of the Capital Stock (including any sale, disposition or other transfer following which the applicable Notes Guarantor is no longer a Wholly Owned Restricted Secured Notes
Subsidiary) of the applicable Notes Guarantor if such sale, disposition, exchange or other transfer is made in a manner not in violation of the Indenture; 

(b) such Notes Guarantor becoming an Unrestricted Subsidiary or an Excluded Subsidiary; 

(c) the release or discharge of the guarantee by such Notes Guarantor of the First Lien Credit Facility or other indebtedness (including the
Second Lien Credit Facility) or the guarantee of any other indebtedness which resulted in the obligation to guarantee the Secured Notes; 

(d) the Company’s exercise of its legal defeasance option or covenant defeasance option with respect to the Secured Notes pursuant to
the Indenture or the Company’s discharge of its obligations with respect to the Secured Notes pursuant to the Indenture; and 
 (e) as
described under Article IX of the Indenture. 
 (3) A Secured Notes Guarantee as to any Subsidiary of New Parent will be automatically
released upon the applicable Subsidiary ceasing to be a Subsidiary of New Parent as a result of any foreclosure of any pledge or security interest securing the Credit Facilities or other exercise of remedies in respect thereof.

 In connection with any termination or release pursuant to this Section 2.8, the Trustee shall execute and
deliver to the Company all documents that the Company shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to this Section 2.8 shall be made without recourse to or warranty by
the Trustee. The Company agrees to pay all reasonable and documented out-of-pocket expenses incurred by the Trustee in connection with the execution and delivery of such documents. 

Section 2.9 Additional Notes Guarantors. 

The Company shall cause each Wholly Owned Restricted Secured Notes Subsidiary that is not an Excluded Subsidiary and that guarantees or
becomes a borrower under the Credit Facilities or that guarantees any other indebtedness of the Company or any of the Notes Guarantors to execute and deliver to the Trustee (i) a supplemental indenture substantially in the form of Exhibit
A hereto pursuant to which such Subsidiary will guarantee payment of the Secured Notes and (ii) joinders to or new Security Documents and take all actions required by the Security Documents to perfect the liens created thereunder. 

Section 2.10 Form of Guarantee. 

The form of Secured Notes Guarantee shall be set forth on the Secured Notes substantially as follows:

executes the certificate of authentication on this Security and (ii) shall be immediately and automatically released and/or terminated, with no further effect, if, (a) during the period commencing 60 days prior to the first public notice of the
Company’s intention to effect the Merger and ending 60 days after the consummation of the Acquisition, a “Rating Event” is deemed to occur or (b) within 61 days after the consummation of the Acquisition, (1) a “Change of Control
Triggering Event” is deemed to occur or (2) it is publicly announced that the rating of the Secured Notes is under consideration for a possible downgrade by any of the Rating Agencies. This Secured Notes Guarantee shall be governed by and

 (2) Notwithstanding anything herein to the contrary, at any time when an Event of Default has
occurred and is continuing and the maturity of the Secured Notes has been accelerated (whether by declaration or otherwise) and the Trustee has delivered a notice of acceleration to the First Lien Collateral Agent, no release of Collateral pursuant
to the provisions of this Seventh Supplemental Indenture or the Security Documents will be effective as against the Holders of the Secured Notes, except as otherwise provided in the First Lien Intercreditor Agreement.

certificates or reports that would otherwise be required by (A) Section 302 or Section 404 of the Sarbanes-Oxley Act of 2002, or related Items 307 or 308 of Regulation S-K, or (B) Item 10(e) of Regulation S-K
