SUPPLEMENT TO THE

BRISTOW GROUP INC.

FY 2018 ANNUAL INCENTIVE COMPENSATION PLAN

Provisions Applicable to Officers

June 12, 2017

PURPOSE

The purpose of this Supplement (“Supplement”) to the Bristow Group Inc. FY 2018 Annual Incentive Compensation Plan (the “Plan”) is to provide additional terms applicable to annual incentive awards made to officers of the Company and to satisfy the performance-based compensation exception to the deductibility limits of Section 162(m) of the Internal Revenue Code, as amended. Terms not defined in this Supplement shall have the meaning assigned thereto in the Plan.

APPLICABILITY

This Supplement applies to officers of Bristow Group Inc. at the Vice President level and above (“Officers”).

THRESHOLD PERFORMANCE GOAL

Officers shall not be entitled to any payments in respect of an annual incentive award for fiscal year 2018, and any annual incentive award for fiscal year 2018 shall be cancelled and forfeited in its entirety as of the end of fiscal year 2018, unless the Company has positive EBITDAR (as defined below) in any fiscal quarter during fiscal year 2018 (the “Threshold Goal”); provided, however, that a fiscal quarter shall not be considered if more than 25% of such fiscal quarter has elapsed prior to the date an award is granted under the Plan. If the Compensation Committee, in its sole discretion, determines that the Company has attained the Threshold Goal, the Compensation Committee shall certify such achievement in writing as soon as reasonably practicable but no later than 90 days after the end of the fiscal year, and such certification shall authorize the maximum amount payable pursuant to annual incentive awards under the Plan for the fiscal year, subject to reduction pursuant to the terms of the Plan and as otherwise determined by the Compensation Committee. For purposes of the Plan, “EBITDAR” means, for the relevant period, the sum of the Company’s (i) net income (or net loss), (ii) interest expense, (iii) income tax expense, (iv) depreciation expense, (v) amortization expense and (vi) rental expense, and the Company’s proportional interest in the sum of (i) net income (or net loss), (ii) interest expense, (iii) income tax expense, (iv) depreciation expense, (v) amortization expense and (vi) rental expense of any of its subsidiaries, as presented in consolidated financial statements, determined in accordance with Generally Accepted Accounting Principles (GAAP).

SUPPLEMENT AND PLAN CONTROL

If an Officer is party to an employment, severance or other agreement with the Company, or is subject to a policy of the Company, in either case, that contains provisions for payment of an annual incentive award upon termination of employment due to any reason other than death, disability or change in control, such provisions shall not apply to an annual incentive award under the Plan unless and until the Threshold Goal has been achieved for any applicable fiscal quarter during the year of such termination.

CLAWBACK POLICY

To the extent applicable to an Officer, all or any portion of an annual incentive award under the Plan may be forfeited if the Officer violates the Company’s Code of Business Integrity (the COBI Clawback Policy), as described in the Company’s Corporate Governance Guidelines and as determined by the Compensation Committee on a case by case basis. In addition, to the extent applicable to an Officer, all or any portion of an annual incentive award under the Plan to the Officer may be forfeited, and all or any portion of any payments received by an Officer with respect to an annual incentive award under the Plan may be subject to recoupment or repayment, pursuant to the Financial Clawback Policy or other Clawback Policy established or adopted by the Company’s Board of Directors from time to time as described in the Company’s Corporate Governance Guidelines.
