                    INFORMATION TO BE INCLUDED IN THE REPORT


Item 8.01.        Other Events.

                  The Company announced that on July 22, 2005, an arbiter has
determined that the previously disclosed agreement between Mason Capital
Management ("Mason") and the Kaman family constitutes a "qualifying alternative
transaction" under the recapitalization agreement, dated June 7, 2005, between
the Kaman family and the Company (the "Recapitalization Agreement") and that
the Kaman family has complied with all the conditions necessary to pursue the
alternative transaction with Mason, the closing of which would terminate the
Recapitalization Agreement.

                  Pursuant to the Recapitalization Agreement, the Company has
five business days to determine whether or not to submit a "substitute
recapitalization proposal" to its shareholders. A "substitute recapitalization
proposal" must offer consideration equivalent to at least $55.65 for each share
of Class B voting common stock. In the event that the Company is to make a
"substitute recapitalization proposal" to its shareholders, the Kaman family
has agreed pursuant to the Recapitalization Agreement, to vote its shares of
Class B voting common stock and Class A nonvoting common stock for approval of
the "substitute recapitalization proposal" and that its ability to pursue the
proposed Mason transaction will be precluded. However, if the recapitalization
agreement were to be later terminated without the "substitute recapitalization
proposal" having been completed, the Kaman family would be free to pursue an
alternative transaction.

                  A copy of the press release is attached hereto as exhibit
99.1 and incorporated herein by reference.

                  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.
