Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On June 21, 2012, Dresser-Rand Group Inc. (the “Company”) entered into a Second Amendment (the “Second Amendment”) to its Credit Agreement, dated March 15, 2011 (as amended by the First Amendment to Credit Agreement, dated May 11, 2011, the “Existing Credit Agreement”, and as further amended by the Second Amendment, the “Credit Agreement”), by and among the Company, D-R Holdings (France) S.A.S, certain lenders named therein (the “Lenders”) and JPMorgan Chase Bank, N.A., as administrative agent. The Second Amendment amends the Existing Credit Agreement to provide for a new Euro-denominated revolving loan facility in an aggregate principal amount at any time outstanding not in excess of €50.0 million (the “Euro Facility”) to be made available to Grupo Guascor, S.L., a Spanish subsidiary of the Company (“Grupo Guascor”), as an additional borrower under the Credit Agreement. The proceeds of the Euro Facility will be used to refinance certain existing indebtedness of Grupo Guascor and for other general corporate purposes.

The loans under the Euro Facility will bear interest at the same rates and will mature on the same date as the loan facilities under the Existing Credit Agreement.

The foregoing summary of certain provisions of the Second Amendment is qualified in its entirety by reference to the text of the Second Amendment, a copy of which is attached hereto as Exhibit 10.1 and is incorporated herein by reference.

The information set forth under Item 1.01 of this Current Report on Form 8-K is hereby incorporated in this Item 2.03 by reference.
