PRESS RELEASE

CIRCOR Issues Update on Leslie Controls Subsidiary’s

Chapter 11 Reorganization Plan

U.S. District Court Hearing Scheduled for January 2011

Burlington, MA – December 23, 2010 – CIRCOR International, Inc. (NYSE: CIR), today announced an update on the timing of the Chapter 11 bankruptcy proceedings of its Leslie Controls, Inc. subsidiary. In its October 28, 2010 press release, CIRCOR announced bankruptcy court confirmation of the Leslie Controls reorganization plan and indicated that it was targeting Leslie’s emergence from bankruptcy for the fourth quarter of 2010, pending required affirmation of the reorganization plan by the U.S. District Court. While the Company had hoped the District Court review would occur during the fourth quarter, the District Court has scheduled the hearing for January 2011.

At the hearing, the District Court will review the Section 524(g) asbestos trust aspects of the reorganization plan and consider appeals lodged by certain of Leslie’s insurers. Upon entry of a District Court order of approval and absent a stay pending any further appeals, Leslie and CIRCOR would fund the Section 524(g) asbestos trust once various closing conditions are satisfied and the reorganization plan becomes effective. Leslie’s emergence from bankruptcy and distributions from the trust to claimants would not occur, however, until any subsequent appeals from the District Court’s order are favorably resolved. CIRCOR and Leslie believe that the pending and any subsequent appeals are, and would be, without merit.
