(1) These shares are directly beneficially owned by Crane Merger Co., a wholly owned subsidiary of Crane Co., pursuant to its completion of a tender offer for all outstanding shares of common stock of Merrimac Industries, Inc., which expired on February 2, 2010 at 12:00 midnight (EST). As of the expiration of the tender offer, approximately 2,773,480 shares were validly tendered and not properly withdrawn, and the depositary for the tender offer has also received commitments to tender 23,162 additional shares under the tender offer's guaranteed delivery procedures. The number of shares on this Form 4 represents the shares acquired in the tender offer less the shares already deemed beneficially owned prior to the completion of the tender offer, as described on the Form 3 of Crane Co. and Crane Merger Co. filed on January 4, 2010.
(2) For more information, see Amendment No. 6 to the Schedule TO of Crane Co. and Crane Merger Co. filed with the Securities and Exchange Commission on February 3, 2010.
