This Amendment is the final amendment to the Schedule 13D and constitutes an “exit filing” for the Reporting Person.

The Reporting Person previously owned the 24,918,421 SIR Common Shares as of the Record Date and was entitled to vote such SIR Common Shares at the Shareholder Meeting, even though the Reporting Person sold those SIR Common Shares on October 9, 2018 in the Offering. At the Shareholder Meeting, the Reporting Person voted all of the SIR Common Shares beneficially owned by it as of the Record Date in favor of approval of the Merger and the other transactions contemplated by the Merger Agreement to which the Issuer is a party.
