Except as otherwise specifically provided herein, (i) all computations made pursuant to this Agreement shall be made in accordance with GAAP, and (ii) all financial statements shall be prepared in accordance with GAAP. For purposes of determining compliance with this Agreement (including, without limitation, Section 9, Section 10 and the definition of “Indebtedness”) (including Additional Covenants contained in, or deemed to be included in, this Agreement), any election by the Company to measure any financial liability using fair value (as permitted by Financial Accounting Standards Board Accounting Standards Codification Topic No. 825-10-25 – Fair Value Option, International Accounting Standard 39 – Financial Instruments: Recognition and Measurement or any similar accounting standard), shall be disregarded and such determination shall be made as if such election had not been made. In the event changes to GAAP occur which would impact the calculation of any covenants in Section 10.1, the Company and the holders of the Notes will negotiate in good faith to amend such covenants in a such a way as to maintain the same concept, level and relative cushion as was in effect immediately before the applicable accounting change; provided, that unless and until the Company and the holders of a majority of the aggregate principal amount of Notes outstanding (exclusive of Notes then owned by the Company, any Subsidiary or any of their respective affiliates) reach agreement with respect to any such amendment, (i) such covenants will continue to be calculated in accordance with GAAP as in effect immediately prior to the applicable change in GAAP; and (ii) the Company shall provide to Prudential (during the Issuance Period) and, following the acceptance of any request for purchase of Notes or any issuance of Notes to each Purchaser or holder of a Note, as applicable, financial statements and other documents required under this Agreement or as reasonably requested hereunder setting forth a reconciliation between calculations of such covenants made before and after giving effect to such change in GAAP.

(b) Notwithstanding the foregoing, for purposes of determining compliance with any covenant (including the computation of any financial covenant) contained herein, all liability amounts shall be determined excluding any liability relating to any operating lease, all asset amounts shall be determined excluding any right-of-use assets relating to any operating lease, all amortization amounts shall be determined excluding any amortization of a right-of-use asset relating to any operating lease, and all interest amounts shall be determined excluding any deemed interest comprising a portion of fixed rent payable under any operating lease, in each case to the extent that such liability, asset, amortization or interest pertains to an operating lease under which the covenantor or a member of its consolidated group is the lessee and would not have been accounted for as such under GAAP as in effect on December 31, 2015; provided that if any Material Credit Facility classifies such leases using any accounting method other than the method set forth above, this Agreement shall similarly no longer classify such leases pursuant to the method set forth above and shall be determined in accordance with clause (a) of this Section 22.2.”

“Section 22.4 Construction, Etc. (a) Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person.

(b)Any reference herein to a merger, amalgamation, consolidation, assignment, sale, disposition or transfer, or similar term, shall be deemed to apply to a division of or by a limited liability company or limited partnership, or an allocation of assets to a series of a limited liability company or limited partnership (or the unwinding of such a division or allocation), as if it were a merger, amalgamation, consolidation, assignment, sale, disposition or transfer, or similar term, as applicable, to, of or with a separate Person.
