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 asset exchange transaction consummated on November 9, 2017, the dismissal of the Parties’ rate case filed in 2016 or associated orders in connection therewith). The aggregate amount of 2017 Incremental CapEx has been restated to $4,217,866, with a weighted average in-service date of March 1, 2017. The aggregate amount of estimated 2017 Incremental CapEx included in the Eighth Amended Supplement was $4,553,684, with a weighted average in-service date of June 1, 2017.

* Represents the aggregate amount of Incremental CapEx the Parties expect to be placed in service in 2018. Rent supplements with respect to this Incremental CapEx were agreed to and memorialized as part of the Eighth Amended Supplement. Of the 2018 Incremental CapEx, $0 is expected to be in service as of the balance sheet date reflected in Lessee’s first 2018 Regulatory Order (“First 2018 CapEx”), $0 is expected to be in service as of the balance sheet date reflected in Lessee’s second 2018 Regulatory Order (“Second 2018 CapEx”), and an aggregate of $759,766 is expected to be placed in service throughout the remainder of 2018 (“2018 Stub-Year CapEx”) and included in the first 2019 Regulatory Order. The Parties expect the First 2018 CapEx, Second 2018 CapEx and 2018 Stub-Year CapEx, collectively, to have a weighted average in-service date of November 1, 2018. The Parties expect the first 2018 Regulatory Order to be effective on June 1, 2018, the second 2018 Regulatory Order to be effective on September 1, 2018 and the first 2019 Regulatory Order to be effective on May 1, 2019.
