Each Notes Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice to or further assent from it, and that it will remain bound upon its guarantee notwithstanding any extension or renewal of any Guaranteed Obligation. Each Notes Guarantor waives presentment to, demand of payment from and protest to the Company of any of the Guaranteed Obligations, and also waives notice of acceptance of its guarantee and notice of protest for nonpayment.

First Supplemental Indenture

Section 2.2 Guaranty of Payment.

Each Notes Guarantor further agrees that its guarantee hereunder constitutes a guarantee of payment when due (whether at stated maturity, by acceleration or otherwise) and not of collection, and waives any right to require that any resort be had by the Trustee or any other Secured Party to any security held for the payment of the Guaranteed Obligations or to any balance of any deposit account or credit on the books of the Trustee or any other Secured Party in favor of the Company or any other Person.

Section 2.3 No Limitations.

Except for termination or release of a Notes Guarantor’s obligations hereunder as expressly provided for in Section 2.8 and Article IV, the obligations of each Notes Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense or set-off, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise (other than defense of payment or performance). Without limiting the generality of the foregoing, the obligations of each Notes Guarantor hereunder, to the fullest extent permitted by applicable law, shall not be discharged or impaired or otherwise affected by: (i) the failure of 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

First 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

First 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;

(e) as described under Article IX of the Indenture.

First Supplemental 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.

of the First Lien Intercreditor Agreement or as provided hereby or in the Security Documents. The applicable assets included in the Collateral shall be automatically released from the liens securing the Secured Notes, and the applicable Notes Guarantor shall be automatically released from its obligations under this First Supplemental Indenture and the Security Documents, under any one or more of the following circumstances:

(a) in respect of the property and assets of a Notes Guarantor, upon the consummation of any transaction permitted by the Indenture as a result of which such Notes Guarantor ceases to be a Subsidiary of New Parent or otherwise ceases to be a Pledgor (as defined in the Collateral Agreement), and such Notes Guarantor shall be automatically released from its obligations hereunder and under the Security Documents, all without delivery of any instrument or performance of any act by any party, and all rights to the Collateral shall revert to such Notes Guarantor;

(b) upon any sale or other transfer by the Company or any Notes Guarantor of any Collateral that is permitted under the Indenture to any Person that is not the Company or a Notes Guarantor (including in connection with a condemnation or casualty event), or upon the effectiveness of any written consent to the release of the security interest granted by the Collateral Agreement in any Collateral pursuant to the Indenture, the security interest in such Collateral securing the Secured Notes shall be automatically released, all without delivery of any instrument or performance of any act by any party;

(c) to enable the Company or any Notes Guarantor to consummate the disposition (other than any disposition to the Company or another Notes Guarantor) of such property or assets and to enable any release described in Section 5.15 of the Collateral Agreement;

(d) in respect of the property and assets of a Notes Guarantor, upon such Notes Guarantor becoming an Unrestricted Subsidiary or an Excluded Subsidiary, and such Notes Guarantor shall be automatically released from its obligations hereunder and under the Security Documents;

(e) in respect of the property and assets of a Notes Guarantor, upon the release or discharge of the pledge granted by such Notes Guarantor to secure the First Lien Credit Facility Obligations or any other indebtedness or the guarantee of any other indebtedness which resulted in the obligation to become a Notes Guarantor with respect to the Secured Notes;

(f) as described under Article IX of the Indenture; and

(g) in accordance with Article IV hereof.

In addition, the security interests granted pursuant to the Security Documents securing the Secured Notes Obligations with respect to the Secured Notes shall automatically terminate and/or be released all without delivery of any instrument or performance of any act by any party, and all rights to the Collateral shall revert to the applicable Pledgors as of the date upon (i) all Obligations under the Secured Notes and the Indenture (other than contingent or unliquidated obligations or liabilities not then due) have been paid in full in cash or immediately available funds or (ii) a legal defeasance or covenant defeasance or discharge under Article XII of the Indenture.

First Supplemental Indenture

(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 First 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.

(3) To the extent necessary and for so long as required for any Subsidiary of the New Parent not to be subject to any requirement pursuant to Rule 3-16 of Regulation S-X under the Securities Act to file separate financial statements with the SEC (or any other governmental agency), the Capital Stock of such Subsidiary of the New Parent (the “Regulation S-X Excluded Collateral”) shall not be included in the Collateral with respect to the Secured Notes so affected and shall not be subject to the liens securing the Secured Notes and the Secured Notes Obligations in accordance with and only to the extent provided in the Security Documents.

Section 3.5 Powers Exercisable by Receiver or Trustee.

In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article III upon the Company or the Notes Guarantors with respect to the release, sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Company or any Notes Guarantor or of any officer or officers thereof required by the provisions of this Article III; and if the Trustee or the First Lien Collateral Agent shall be in the possession of the Collateral under any provision of this First Supplemental Indenture, then such powers may be exercised by the Trustee or the First Lien Collateral Agent, as the case may be.

Section 3.6 Release upon Termination of the Company’s Obligations.

In the event that (i) the Company delivers to the Trustee, in form and substance acceptable to it, an Officer’s Certificate and Opinion of Counsel certifying that all the Obligations under the Secured Notes have been satisfied and discharged by the payment in full of the Company’s obligations under the Secured Notes, and all such Obligations have been so satisfied, or (ii) a discharge, legal defeasance or covenant defeasance occurs under Article XII of the Indenture with respect to the Secured Notes, the Trustee shall deliver to the Company and the First Lien Collateral Agent a notice stating that the Trustee, on behalf of the Holders of the Secured Notes, disclaims and gives up any and all rights it has in or to the Collateral with respect the Secured Notes, and any rights it has under the Secured Notes, and upon receipt by the First Lien Collateral Agent of such notice, the First Lien Collateral Agent shall be deemed not to hold a lien in the Collateral with respect to the Secured Notes on behalf of the Trustee and shall (or shall direct the First Lien Collateral Agent to) do or cause to be done all acts reasonably necessary to release such lien, with respect to the Secured Notes, as soon as is reasonably practicable.

First Supplemental Indenture

Following any such release with respect to the Secured Notes, all property and assets of the Company and each Notes Guarantor not required to be pledged for the benefit of the Secured Notes pursuant to the 2020 Notes Officer’s Certificate shall constitute “Specified Excluded Collateral” with respect to the Secured Notes.

ARTICLE V

(ii) within 15 days after the time period specified in the SEC’s rules and regulations for non-accelerated filers, quarterly reports of the Reporting Entity for such fiscal quarter containing the information that would have been required to be contained in a quarterly report on Form 10-Q (or any successor or comparable form) if the Reporting Entity had been a reporting company under the Exchange Act, except to the extent permitted to be excluded by the SEC; and

(iii) within 15 days after the time period specified in the SEC’s rules and regulations for filing current reports on Form 8-K, current reports containing substantially all of the information that would be required to be filed in a Current Report on Form 8-K under the Exchange Act on the operative date of the First Supplemental Indenture pursuant to Sections 1, 2 and 4, Items 5.01, 5.02(a)–(d) (other than compensation information), 5.03(b) and Item 9.01 (only to the extent relating to any of the foregoing) of Form 8-K if the Reporting Entity had been a reporting company under the Exchange Act; provided, however, that no such current reports will be required to be furnished if the Company or any direct or indirect parent of the Company determines in its good faith judgment that such event is not material to Holders or the business, assets, operations, financial position or prospects of the Company and its Affiliates, taken as a whole.

First Supplemental Indenture

If at any time the Company or any direct or indirect parent of the Company has made a good faith determination to file a registration statement with the SEC with respect to an initial public offering of such Person’s Capital Stock, the Company will not be required to disclose any information or take any actions that, in the good faith view of the Company, would violate the securities laws or the SEC’s “gun jumping” rules or otherwise have an adverse effect on such initial public offering.

Notwithstanding the foregoing, (1) the Company (and the applicable Reporting Entity) will not be required to furnish any information, certificates or reports that would otherwise be required by (A) Section 302 or Section 404 of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002, or related Items 307 or 308 of Regulation S-K, or (B) Item 10(e) of Regulation S-K promulgated by the SEC with respect to any non-generally accepted accounting principles financial measures contained therein, (2) such reports will not be required to contain financial information required by Rule 3-09, Rule 3-10 or Rule 3-16 of Regulation S-X or include any exhibits or certifications required by Form 10-K or Form 10-Q (or any such successor or comparable forms) or related rules under Regulation S-K, and (3) such reports shall be subject to exceptions and exclusions consistent with the presentation of financial and other information in the preliminary offering memorandum for the Second Priority Senior Secured Notes due 2023 and shall not be required to present compensation or beneficial ownership information.

The financial statements, information and other documents required to be provided as described above, may be those of (1) the Company or (2) any direct or indirect parent of the Company (any such entity described in clause (1) or (2), a “Reporting Entity”), so long as, in the case of (2), either (A) such direct or indirect parent of the Company will not conduct, transact or otherwise engage, or commit to conduct, transact or otherwise engage, in any business or operations other than its direct or indirect ownership of all of the equity interests in, and its management of the Company or (B) such direct or indirect parent of the Company is or becomes a guarantor of the Secured Notes; provided that, if the financial information so furnished relates to such direct or indirect parent of the Company pursuant to (2)(A) above, the same is accompanied by a reasonably detailed description of the quantitative differences between the information relating to such parent, on the one hand, and the information relating to the Company and the guarantors of the Secured Notes on a standalone but consolidated basis, on the other hand.

In addition to providing such information to the Trustee, the Company will make available to the Holders, prospective investors and securities analysts the information required to be provided pursuant to clauses (i), (ii) or (iii) of this Section, by posting such information to the website of the Company (or the website of any direct or indirect parent of the Company) or on IntraLinks or any comparable online data system or website.

clauses (a)(i) and (a)(ii) of this Section 5.1, and prior to the date of each such conference call, the Reporting Entity will announce the time and date of such conference call and either include all information necessary to access the call in such announcement or inform Holders of the Secured Notes, prospective investors and securities analysts how they can obtain such information, including, without limitation, the applicable password or other login information (if applicable).

(c) Notwithstanding the foregoing, the Company will be deemed to have furnished such reports referred to above to the Trustee and Holders if the Company or a Reporting Entity has filed such reports with the SEC via the ▇▇▇▇▇ filing system (or any successor system) and such reports are publicly available. In addition, the requirements of this covenant shall be deemed satisfied by the posting of reports that would be required to be provided to the Holders on the Company’s website (or the website of any direct or indirect parent of the Company). Furthermore, (1) the time requirements set forth in clause (ii) of the first paragraph of this covenant shall be satisfied if the quarterly reports for the fiscal quarters ending March 31, 2016, June 30, 2016 and September 30, 2016 are filed within 75 days after the end of such fiscal quarter and (2) the time requirements set forth in clause (i) of the first paragraph of this covenant shall be satisfied if the annual report for the fiscal year ending December 31, 2016 is filed within 120 days after the end of such fiscal year.
