INFORMATION TO BE INCLUDED IN THE REPORT Item 8.01. Other Events. The Company announced that on June 29, 2005 it received a letter from Mason Capital Management ("Mason"), who is also a party to the previously disclosed agreement between Mason and the Kaman family, in which Mason represented that it owned 55,642 shares of Class B common stock and requested that it be permitted to review a list of the holders of Class B common stock in connection with its intention to purchase all outstanding shares of Class B common stock. As of this date, the Company has refused to comply with Mason's request as it believes that Mason has not met the statutory requirements necessary to obtain such a stockholder list. In addition, on July 6, 2005, as permitted under the Company's previously disclosed recapitalization agreement with members of the Kaman family, the Company submitted certain questions to arbitration as to whether or not the proposed transaction contemplated by the previously disclosed agreement between the Kaman family and Mason constitutes a "qualifying alternative transaction" under the recapitalization agreement. The Company also sent letters to the Kaman family and Mason requesting certain information regarding their discussions with respect to the Kaman family's shares of Class B common stock. Further detail on the proposed recapitalization and recapitalization agreement can be found in the recapitalization agreement, which was filed as Exhibit 2.1 to a Form 8-K filed by the Company on June 8, 2005.
