Item 1.01:         Entry into a Material Definitive Agreement.

                As previously reported on a Form 8-K filed on June 14, 2007, Cooper-Standard Automotive Inc. (the “Company”), a wholly-owned subsidiary of Cooper-Standard Holdings Inc. (“Holdings”) and CSA Germany GmbH & Co. KG, a wholly-owned German subsidiary of the Company, entered into a Sale and Purchase Agreement with Automotive Sealing Systems S.A. (the “Seller”) on June 9, 2007, pursuant to which the Company and certain of its affiliates agreed to acquire certain parts of the Metzeler Automotive Profile Systems ("MAPS") automotive weather sealing business of the Seller, including the outstanding capital stock of certain of the Seller’s direct and indirect subsidiaries and certain other assets, for Euro 100,000,000 in cash (the “MAPS Acquisition”), subject to purchase price adjustments and certain closing conditions.

                On July 26, 2007, the Company entered into the Second Amendment to Credit Agreement (the “Amendment”), among Holdings, the Company, Cooper-Standard Automotive Canada Limited, a corporation organized under the laws of Ontario, Steffens Beheer BV, a corporation organized under the laws of the Netherlands, the lenders who are party thereto, Deutsche Bank Trust Company Americas, as administrative agent, Lehman Commercial Paper Inc., as syndication agent, and Goldman Sachs Credit Partners, L.P., UBS Securities LLC and The Bank of Nova Scotia, as co-documentation agents. The Amendment permits the MAPS Acquisition, and the Company therefore plans, upon consummation of the MAPS Acquisition, to borrow up to an incremental Euro 65,000,000 through a term loan under the Credit Agreement (as amended) to finance, in part, the MAPS Acquisition and to pay related fees and expenses. The Amendment also provides for a new dual dollar and Euro currency borrowing facility accessible, upon consummation of the MAPS Acquisition, directly by a European subsidiary of the Company in an amount up to USD 35,000,000. In addition, the Amendment further provides some additional operating and investment flexibility for the Company. The foregoing description of the Amendment does not purport to be complete, and is qualified in its entirety by reference to the Amendment itself, a copy of which is attached hereto as Exhibit 10.1 and incorporated herein by reference in its entirety.
