2. SU Working Capital Package. With respect to the SU Working Capital Package, the parties acknowledge and agree that:

(a) The definition of “SU Working Capital Package” as set forth in the Merger Agreement shall be deemed amended to read as follows:

To the extent the actual amount of an ad valorem or property Tax is not known at the time adjustments are to be made pursuant to Section 2.04, the Parties shall utilize the most recent information available in estimating the amount of such Tax for purposes of such adjustment.

(b) Oncor delivered a statement of the amount referenced in clause (c) in the definition of “SU Working Capital Package” in connection with the delivery of its Estimated Closing Statement to SDTS. Oncor shall deliver a statement of the proposed final amount with respect to the amount referenced in clause (c) in the definition of “SU Working Capital Package” in connection with its delivery of the Final Oncor AssetCo Statement. SU shall have the opportunity to challenge such amount pursuant to the procedures set forth in Section 1.06(c) through 1.06(f), mutatis mutandis, and the applicable party shall pay any adjustment resulting therefrom.

(c) The SU Net Working Capital Estimate and the Net Book Value of the SU Working Capital Package as finally determined pursuant to Section 2.04 of the Merger Agreement shall be determined by applying the revised definition of “SU Working Capital Package”.
