(b) The initial allocation of expenses in the intercompany arrangements to be put in place pursuant to the Pre-Closing Steps shall be consistent with the Quality of Earnings report attached hereto as Exhibit A, and Investor hereby consents to such allocation.

(c) Notwithstanding the listing of the platform known as “IDC” in Section (v)(A)(4) of the definition of “Enterprise Transferred Assets” in Exhibit A of the Framework Agreement, the platform known as “IDC” shall be an Excluded Asset.

Section 1.3 Future Allocations.

(a) The parties agree that, on an annual basis following the Closing, the Company shall commence and complete a detailed study (the “Time Use Study”) of the time spent by the employees of the Company and its Subsidiaries on North America Enterprise Business matters and Remaining Business matters, respectively, with the Time Use Study overseen by a committee of the Company’s board of directors (the “Board”) appointed in accordance with Section 2.8 of the Stockholders Agreement (the “Allocation Committee”). Following the completion of each Time Use Study (the first of which shall be completed no later than October 31, 2022 and each thereafter no later than 30 days prior to the end of each subsequent fiscal year), the Board will, to the extent warranted by the results of the Time Use Study, in the Board’s reasonable judgment, modify the allocation of costs between the North America Enterprise Business and the Remaining Business for the then-subsequent fiscal year. As part of the Time Use Study, the Allocation Committee shall consult with the Company’s auditors as to the detailed allocation of costs for the subsequent fiscal year (and any methodology utilized therefore), and shall consider any feedback provided by the auditor.

(b) Following the Closing, prior to the completion of the first Time Use Study and, solely if the Board approves modifications of the allocation of costs pursuant to Section 1.2(a) hereof in response to such Time Use Study, the implementation of such modifications, the Company shall not incur any third party term loan indebtedness for borrowed money.
