The following constitutes Amendment No. 7 to the Schedule 13D filed by the undersigned (“Amendment No. 7”). This Amendment No. 7 amends the Schedule 13D as specifically set forth herein.

Item 4 is hereby amended to add the following:

On November 15, 2018, the Issuer completed its previously-announced business combination with Tidewater Inc. (“Tidewater”) pursuant to the Agreement and Plan of Merger (the “Merger Agreement”), dated July 15, 2018, between the Issuer and Tidewater. Pursuant to the terms of the Merger Agreement, (i) each issued and then-outstanding Share or right to receive a Share of the Issuer was automatically converted into the right to receive 1.100 shares of Tidewater common stock, with cash paid in lieu of any fractional share and (ii) each then-outstanding Issuer warrant was automatically converted into the right to receive 1.100 shares of Tidewater common stock upon payment to Tidewater of the applicable exercise price, subject to all other terms and conditions of the applicable Issuer warrant agreement, including cash paid in lieu of any fractional share. As a result, all Shares, New Existing Equity Warrants and vested restricted stock units of the Issuer owned by the Reporting Persons were disposed of in exchange for the foregoing merger consideration. Accordingly, the Reporting Persons no longer beneficially own any securities of the Issuer.

Item 5 is hereby amended and restated to read as follows:

The Reporting Persons no longer beneficially own any securities of the Issuer. There were no transactions in the securities of the Issuer by the Reporting Persons during the past 60 days except as set forth in Item 4.

The Reporting Persons have ceased to be beneficial owners of more than 5% of the Shares.
