Item 1.01. Entry into a Material Definitive Agreement.

Senior Secured Credit Facilities — On December 22, 2011, Bristow Group Inc. (the “Company”) entered into the First Amendment to its Amended and Restated Revolving Credit and Term Loan Agreement (the “Amendment”) by and among the Company, the lenders from time to time party thereto and SunTrust Bank, as administrative agent (the “Administrative Agent”), which amends that certain Amended and Restated Revolving Credit and Term Loan Agreement, dated as of November 22, 2010 (as amended by the Amendment, the “Amended Credit Agreement”), by and among the Company, the Lenders from time to time party thereto and the Administrative Agent, as administrative agent, issuing bank and swingline lender, JPMorgan Chase Bank, National Association, and Bank of America, N.A., as Co-Syndicated Agents and Wells Fargo Bank, National Association, Regions Bank and BBVA Compass as Co-Documentation Agents. The Amendment (i) increases the commitments under the revolving credit facility from $175 million to $200 million, (ii) increases the Company’s term loan borrowings from $200 million to $250 million, (iii) extends the maturity date of the revolving facility and the term loans from November 2015 to December 2016 and (iv) reduces the interest rates and commitment fees with respect to the revolving facility and term loans.

Under the Amended Credit Agreement, borrowings under the revolving credit facility bear interest at an interest rate equal to, at the Company’s option, either the Base Rate or LIBOR (or EURIBO, in the case of Euro-denominated borrowings) plus the applicable margin. “Base Rate” means the higher of (1) the prime rate and (2) the Federal Funds rate plus 0.50% per annum. The applicable margin for borrowings ranges from 0.000% to 2.25%, depending on whether the Base Rate or LIBOR is used, and is determined based on the Company’s leverage ratio pricing grid. In addition, under the Amended Credit Agreement, the Company is required to pay fees on the daily unused amount of the revolving facility in an amount per annum equal to applicable percentage, which ranges from 0.25% to 0.50% and which is determined based on the Company’s leverage ratio pricing grid. Fees owed on the letters of credit issued under the revolving credit facility are equal to the applicable margin for LIBOR borrowings.
