Item 1.01 Entry into a Material Definitive Agreement.

On December 20, 2005, Circor International, Inc. (the “Company”) entered into a Credit Agreement (as amended, modified and supplemented, the “Credit Agreement”), dated as of December 20, 2005, by and among the Company, as Borrower; certain domestic subsidiaries of the Company, as Subsidiary Guarantors; the Lenders party thereto; KeyBank National Association, as Administrative Agent; and Bank of America, NA, as Syndication Agent. The Credit Agreement provides for a $95 million revolving line of credit and letter of credit facility. The facility expires on the earlier of December 20, 2010 or the date on which the revolving line of credit commitments are terminated by the Lenders in accordance with the Credit Agreement and replaces the Company’s existing revolving credit facility which had no amounts outstanding thereunder, and was terminated, as of December 19, 2005. As of the date of this current report, there were no loans outstanding under the Company’s new revolving credit facility and no obligations outstanding under letters of credit. There are approximately $3.4 million of outstanding letters of credit issued under the former revolving credit facility, which will be reissued under the new December 20, 2005 revolving credit facility in the near future.

The borrowings under the revolving line of credit and letter of credit bear interest and fees as set forth in the Credit Agreement. The Company may repay any borrowings under the Credit Agreement at any time.

Under the Credit Agreement, the Company must comply with various financial and non-financial covenants, including certain financial ratios. Under certain circumstances the Company and the Subsidiary Guarantors must pledge to the Administrative Agent certain equity interests in certain subsidiaries. The Lenders are entitled to accelerate repayment of the loans under the Credit Agreement upon the occurrence of any of various events of default.
