Item 1.01. Entry into a Material Definitive Agreement.

On November 27, 2018, Bristow Group Inc. (the “ Company ”) entered into a Securities Purchase Agreement (the “ Securities Purchase Agreement ”) with certain private investors (collectively, the “ Note Purchasers ”), whereby the Company has agreed to issue, and the Note Purchasers have agreed to purchase, a minimum of $135 million aggregate principal amount of a new series of convertible senior secured notes of the Company (the “ Convertible Notes ”). The Note Purchasers also have the option, exercisable until December 14, 2018, to purchase up to an additional $15 million of Convertible Notes. The Convertible Notes will be issued under an indenture (the “ Indenture ”) to be dated as of the closing date (the “ Closing ”) of the previously announced acquisition by Bear Acquisition I, LLC, a wholly owned subsidiary of the Company (“ Purchaser ”), of all the issued and outstanding shares of Columbia Helicopters, Inc. (“ Columbia ”). The Convertible Notes will also be secured by a pledge of the common stock of Columbia, an unrestricted subsidiary, held by the Company pursuant to a pledge agreement (the “ Pledge Agreement ”) to be entered into concurrently with the Indenture. The Convertible Notes have an initial conversion premium of 20% to the three-day volume weighted average price of the Company’s common stock for the period ended as of November 27, 2018. In addition, the Company has agreed that one of its unrestricted subsidiaries which will be the survivor of a merger with Purchaser and which will subsequently merge concurrently with the Closing with and into Columbia will issue warrants (the “ Warrants ”) to purchase up to between 54% and 60% shares of the capital stock of Columbia, depending on the principal amount of Convertible Notes issued, in the event of certain events of bankruptcy, insolvency or reorganization with respect to the Company.

The Convertible Notes and the warrants will be issued in a private placement exempt from the registration requirements of the Securities Act, in reliance on the exemptions set forth in Section 4(a)(2) of the Securities Act of 1933, as amended. The closing of the private placement is subject to the satisfaction of certain conditions, including (1) the execution and delivery of definitive documentation with respect to the Convertible Notes in accordance with the terms set forth in the Securities Purchase Agreement, (2) the Closing and (3) the absence of any material adverse effect with respect to Columbia’s business. The foregoing description of the Securities Purchase Agreement, the Indenture, the Convertible Notes, the Pledge Agreement and the Warrants does not purport to be complete and is subject to and qualified in its entirety by reference to the Securities Purchase Agreement, the Indenture, the Convertible Notes, the Pledge Agreement and the Warrants, copies or forms of which are attached hereto as Exhibits 10.1, 10.2, 10.3, 10.4 and 10.5.
