This Amendment No. 4 is being filed as a result of the disposition of the Reporting Persons’ Common Stock pursuant to that certain Agreement and Plan of Merger (the “Merger Agreement”) by and among the Issuer, KLX Energy Services Holdings, Inc., a Delaware corporation (“KLXE”), Krypton Intermediate LLC, a Delaware limited liability company and indirect wholly owned subsidiary of KLXE, and Krypton Merger Sub Inc., a Delaware corporation and an indirect wholly owned subsidiary of KLXE (“Merger Sub”).

Except as otherwise specified in this Amendment No. 4, all items left blank remain unchanged in all material respects and any items which are reported are deemed to amend the corresponding items in the Original 13D, as amended. Capitalized terms used herein but not defined herein have the respective meanings ascribed to them in the Original 13D, as amended.

Item 5. Interest in Securities of the Issuer.

Item 5 of the Original 13D is hereby amended and supplemented to include the following:

As a result of the events described in Item 4 (which Item 4 is incorporated herein by reference), as of July 28, 2020, the Reporting Persons do not own any shares of the Common Stock of the Issuer. Therefore, the Reporting Persons ceased to be the beneficial owners of more than 5% of the Issuer’s Common Stock. Consequently, this Amendment No. 4 constitutes an exit filing for the Reporting Persons.
