material to the Holders or the business, assets, operations, financial positions or prospects of the Company and its Restricted Subsidiaries taken as a whole, (ii) an exhibit or a summary of the terms of, any employment or compensatory
arrangement, agreement, plan or understanding between the Company or any of its Subsidiaries and any director, officer or manager of the Company or any of its Subsidiaries, (iii) copies of any agreements, financial statements or other items

required by FASB Accounting Standards Codification Topic 280), (ii) separate financial 

  
 4 













 
statements or other information contemplated by Rules 3-05, 3-09, 3-10, 3-16 or 4-08 of Regulation S-X (or any successor provisions) or any schedules required by Regulation
S-X, (iii) information required by Regulation G under the Exchange Act or Item 10, Item 302, Item 402 or Item 601 of Regulation S-K (or any successor provision),
(iv) XBRL exhibits, (v) earnings per share information, (vi) information regarding executive compensation and related party disclosure related to SEC Release Nos. 33-8732A, 34-54302A and IC-27444A, and (vii) other information customarily excluded from an offering memorandum, including any information that is not otherwise of the type and
form currently included in the offering memorandum relating to the Notes. In addition, notwithstanding the foregoing, the Company will not be required to (i) comply with Sections 302, 906 and 404 of the Sarbanes-Oxley Act of 2002, as amended,
or (ii) otherwise furnish any information, certificates or reports required by Items 307 or 308 of Regulation S-K (or any successor provision). To the extent any such information is not so filed or
furnished, as applicable, within the time periods specified above and such information is subsequently filed or furnished, as applicable, the Company will be deemed to have satisfied its obligations with respect thereto at such time and any Default
with respect thereto shall be deemed to have been cured; provided that such cure shall not otherwise affect the rights of the Holders under “— Events of Default” if Holders of at least 30% in principal amount of the outstanding
Notes have declared the principal, premium, if any, interest and any other monetary obligations on all the outstanding Notes to be due and payable immediately and such declaration shall not have been rescinded or cancelled prior to such cure. In
addition, to the extent not satisfied by the foregoing, the Company will agree that, for so long as any Notes are outstanding, it will furnish to Holders and to securities analysts and prospective investors, upon their request, the information
required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 
 Substantially concurrently with the
furnishing or making such information available to the Trustee pursuant to the immediately preceding paragraph, the Company shall also use its commercially reasonable efforts to post copies of such information required by the immediately preceding
paragraph on a website (which may be nonpublic, require a confidentiality acknowledgement and may be maintained by the Company or a third party) to which access will be given to Holders, bona fide prospective investors in the Notes (which
prospective investors shall be limited to “qualified institutional buyers” within the meaning of Rule 144A of the Securities Act or non-U.S. persons (as defined in Regulation S under the
Securities Act) that certify their status as such to the reasonable satisfaction of the Company), and securities analysts (to the extent providing analysis of an investment in the Notes) and market making financial institutions that are reasonably
satisfactory to the Company who agree to treat such information and reports as confidential; provided that the Company may deny access to any competitively-sensitive information and reports otherwise to be provided pursuant to this paragraph
to any Holder, bona fide prospective investors, security analyst or market maker that is a competitor of the Company and its Subsidiaries to the extent that the Company determines in good faith that the provision of such information and reports to
such Person would be competitively harmful to the Company and its Subsidiaries. The Company may condition the delivery of any such reports to such Holders, prospective investors in the Notes and securities analysts and market making financial
institutions on 

  
 5 













 
the agreement of such Persons to (i) treat all such reports (and the information contained therein) and information as confidential, (ii) not use such reports (and the information
contained therein) and information for any purpose other than their investment or potential investment in the Notes and (iii) not publicly disclose any such reports (and the information contained therein) and information.  
 If the Company has designated any of its Subsidiaries as an Unrestricted
Subsidiary and such Unrestricted Subsidiary or group of Unrestricted Subsidiaries, if taken together as one Subsidiary, would constitute a Significant Subsidiary of the Company, then the annual and quarterly information required by clauses
(1) and (2) of the first paragraph of this covenant will include a presentation of selected financial metrics (in the Company’s sole discretion) of such Unrestricted Subsidiaries as a group in the “Management’s Discussion
and Analysis of Financial Condition and Results of Operations.” 
 So long as any Notes are outstanding, the Company
will also: 
 (1) after: 
 (i)
furnishing to the Holders the annual and quarterly information and reports required by clause (1) and clause (2), as applicable, of the first paragraph of this “Reporting Covenant”; or 

(ii) furnishing to the Holders, at the option and in the sole discretion of the Company (who shall not be obligated to so furnish), a summary
condensed consolidated annual or quarterly income statement and balance sheet, as applicable, without notes thereto, and a summary discussion of the results of operations for the relevant reporting period, promptly hold a conference call to discuss
such information and reports or summary information and the results of operations for the relevant reporting period (which conference call, for the avoidance of doubt, may be held prior to such time that the annual or quarterly information and
reports required by clause (1) and clause (2) of the first paragraph of this “Reporting Covenant” are furnished to Holders); and (2) announce by press release to the appropriate nationally recognized wire services or post to
the website of the Company or on a non-public, password-protected website or online data system maintained by the Company or a third party prior to the date of the conference call required to be held in
accordance with clause (1) of this paragraph, the time and date of such conference call and either including all information necessary to access the call or informing Holders, bona fide prospective investors, market makers and securities
analysts how they can obtain such information. 
 Notwithstanding any other provision of the Indenture, the sole remedy for
an Event of Default relating to the failure to comply with the reporting obligations described under this covenant, will for the 365 days after the occurrence of such Event of Default consist exclusively, to the extent permitted by applicable law,
of the right to receive additional interest on the principal amount of the Notes at a rate equal to 0.50% per annum. This additional interest will be payable in the same manner and subject to the same terms as other interest payable under the
Indenture. This additional interest will accrue on all 

  
 6 













 
outstanding Notes from and including the date on which an Event of Default relating to a failure to comply with the reporting obligations described above this covenant first occurs to, but
excluding the 365th day thereafter (or such earlier date on which the Event of Default relating to such reporting obligations is cured or waived) and upon the occurrence of such Event of Default, the Company shall deliver to the Trustee an
Officer’s Certificate (upon which the Trustee may rely conclusively) stating (i) the amount of such additional interest that is payable and (ii) the date that such additional interest begins to accrue. Unless and until the Trustee
receives such a certificate, the Trustee may assume without inquiry that no such additional interest is payable and the Trustee shall not have any duty to verify the Company’s calculations of additional interest. If the Event of Default
resulting from such failure to comply with the reporting obligations is continuing on such 365th day, such additional interest will cease to accrue and the Notes will be subject to the other remedies provided under “— Events of
Default.” 
 The Indenture will permit the Company to satisfy its obligations in this covenant with respect to financial
information relating to the Company by furnishing financial information relating to any direct or indirect parent of the Company (a “Parent Entity”); provided that if such Parent Entity is not a Guarantor, to the extent such
Parent Entity holds assets (other than its direct or indirect interests in the Company) that exceed the lesser of (1) 1% of the consolidated total assets of such Parent Entity and (ii) 1% of the total revenue for the preceding fiscal year of such
Parent Entity, then such information related to such Parent Entity shall be accompanied by consolidating information that explains in reasonable detail the differences between the information relating to such Parent Entity (and other Parent Entities
included in such information, if any), on the one hand, and the information relating to the Company and its Restricted Subsidiaries on a standalone basis, on the other hand. For the avoidance of doubt, the consolidating information referred to in
the proviso in the preceding sentence need not be audited or reviewed by the auditors.  
 Notwithstanding anything to
the contrary set forth above, if the Company or any Parent Entity has furnished the Holders of Notes or filed with the SEC the reports described in the preceding paragraphs with respect to the Company or any Parent Entity, the Company shall be
deemed to be in compliance with the provisions of this covenant. 
 Delivery of reports, information and documents to the
Trustee under the Indenture is for informational purposes only and the information and Trustee’s receipt of the foregoing shall not constitute actual or constructive notice of any information contained therein, or determinable from information
contained therein including the Company’s compliance with any of its covenants thereunder (as to which the Trustee is entitled to rely exclusively on an Officer’s Certificate). The Trustee shall have no duty to review or analyze reports
delivered to it. 
 (d)    The Indenture, with respect to the Notes, and the Notes (for the avoidance of
doubt, including the Global Security for the Notes) are hereby amended by deleting Section 10.08 of the Sixth Supplemental Indenture with respect to the Notes.
