Lease) dated December 31, 2016 (“Eleventh Amended Supplement”). Of the 2017 distribution Incremental CapEx, an aggregate of $53,990,282 was expected to be in service as of
the Effective Date (“First 2017 Distribution CapEx”), with an expected weighted average in-service date of April 1, 2017, and an aggregate of $5,149,712 was expected to be placed in
service throughout the remainder of 2017 (“2017 Stub-Year Distribution CapEx”), with an expected weighted average in-service date of December 1, 2017. 


	**	Represents the aggregate amount of transmission Incremental CapEx the Parties expected to be placed in service in 2017 (as adjusted for the disposition of the Disposed S/B/C Assets on the Effective Date). Rent
supplements with respect to this transmission Incremental CapEx were agreed to and memorialized as part of the Eleventh Amended Supplement. Of the 2017 transmission Incremental CapEx, an aggregate of $10,473,331 was expected to be in service as of
the balance sheet date reflected in Lessee’s first 2017 Regulatory Order (“First 2017 Transmission CapEx”), an aggregate of $48,715,473 was expected to be in service as of the Effective Date and reflected in Lessee’s
second 2017 Regulatory Order (“Pre-Closing Second 2017 Transmission CapEx”), an aggregate of $9,925,480 was expected to be in service after the Effective Date but as of the balance sheet date
reflected in Lessee’s second 2017 Regulatory Order (“Post-Closing Second 2017 Transmission CapEx”) and an aggregate of $0 was expected to be placed in service throughout the remainder of 2017 (“2017 Stub-Year
Transmission CapEx”) and included in the first 2018 Regulatory Order. The Parties expected the First 2017 Transmission CapEx and Pre-Closing Second 2017 Transmission CapEx, collectively, to have a
weighted average in-service date of June 1, 2017 and the Post-Closing Second 2017 Transmission CapEx and 2017 Stub-Year Transmission CapEx, collectively, to have a weighted average in-service date of November 1, 2017. A “Regulatory Order” is defined as either (i) the PUCT’s approval of Lessee’s application for updated wholesale transmission rates or
(ii) final resolution or settlement of a rate case applicable to Lessee’s transmission rates (but, for the avoidance of doubt, does not include the order approving the Exchange Transaction, the dismissal of the Parties’ pending rate
case filed in 2016 or associated orders in connection therewith). The Parties expected the first 2017 Regulatory Order to be effective on May 1, 2017, the second 2017 Regulatory Order to be effective on March 1, 2018, and the first 2018
Regulatory Order to be effective on June 1, 2018. The Parties have agreed that any Rent Validation (within the meaning of the S/B/C Lease) with respect to First 2017 Transmission CapEx, Pre-Closing Second
2017 Transmission CapEx, Post-Closing Second 2017 Transmission CapEx and 2017 Stub-Year Transmission CapEx will use the actual effective dates of the applicable Regulatory Order (to the extent known), but will otherwise be determined in accordance
with Section 3.2(c) of the S/B/C Lease.
