As previously disclosed, on December 18, 2009, Cooper-Standard Holdings Inc., a Delaware corporation (the “Company”), and certain of its subsidiaries entered into a Debtor-In-Possession Credit Agreement (the “Replacement DIP Credit Agreement”) among the Company, Cooper-Standard Automotive Inc., an Ohio corporation (the “U.S. Borrower”), Cooper-Standard Automotive Canada Limited, a corporation organized under the laws of Ontario (the “Canadian Borrower”), and METZELER Automotive Profile Systems GmbH, a German limited liability company (the “German Borrower” and, together with the U.S. Borrower and the Canadian Borrower, the “DIP Borrowers”), various lenders party thereto, Deutsche Bank Trust Company Americas, as the administrative agent, collateral agent and documentation agent, and Deutsche Bank Securities Inc., as syndication agent, sole lead arranger and book runner.

As previously disclosed, the lenders under the Replacement DIP Credit Agreement committed to provide superpriority senior secured term loans to the DIP Borrowers in an aggregate principal amount of $175 million (the “Replacement DIP Facility”), subject to various conditions including the entry by the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”) of a final order (the “Final Order”) approving the Replacement DIP Credit Agreement (together with all related loan documentation) and the borrowings thereunder. The Company’s entry into the Replacement DIP Credit Agreement and the terms thereof were previously disclosed in, and are described under Item 1.01 of, the Company’s Current Report on Form 8-K filed on December 24, 2009, and such description is incorporated by reference herein.

Funding under the Replacement DIP Credit Agreement occurred on December 30, 2009, whereby (i) $75 million was borrowed by the U.S. Borrower, (ii) $50 million was borrowed by the Canadian Borrower and (iii) $50 million was borrowed by the German Borrower and, concurrently with such funding, liens on assets of the DIP Borrowers and certain of their subsidiaries were granted and guarantees of the obligations under the Replacement DIP Credit Agreement were made, in each case on terms and in a manner and pursuant to documentation substantially identical to those previously existing under the Company’s existing Debtor-In-Possession Credit Agreement, dated as of August 5, 2009 (as amended, the “Existing DIP Credit Agreement”), among the Company, the DIP Borrowers, and the various agents and lenders party thereto.

Item 1.02. Termination of a Material Definitive Agreement.

On December 30, 2009, all of the proceeds of the borrowings under the Replacement DIP Facility, together with cash on hand of the DIP Borrowers, were used to repay all borrowings and amounts outstanding under the Existing DIP Credit Agreement, and to pay related fees and expenses. As a result of the repayment of the Existing DIP Credit Agreement (i) all indebtedness thereunder was discharged, (ii) all commitments of the lenders thereunder were terminated, (iii) all liens granted to the lenders thereunder were released and discharged and (iv) all obligations of the credit parties thereunder were released and discharged (other than those that by the terms of the Existing DIP Credit Agreement survive termination).
