Item 1.01     Entry into a Material Definitive Agreement.

        On April 3, 2006, Kadant Inc., a Delaware corporation ("Kadant" and the
"Borrower"), entered into a Third Amendment (the "Amendment") to the Credit
Agreement dated as of May 9, 2005 (as amended to date, the "Credit Agreement"),
among Kadant, the Foreign Subsidiary Borrowers from time to time parties
thereto, the several lenders from time to time parties thereto, and JPMorgan
Chase Bank, N.A., as Administrative Agent. This Amendment increases the total
borrowing capacity under the revolving line of credit from $25 to $35 million,
increases the letter of credit and multi-currency borrowing sublimit to the full
amount of the facility ($35 million), and adds an additional lending participant
to the Credit Agreement, Bank of China, New York branch. The amount we are able
to borrow under the revolving line of credit is the total borrowing capacity
less any outstanding letters of credit and multi-currency borrowings issued
under the Credit Agreement.

        This Amendment was entered into in anticipation of our proposed
acquisition of Jining Huayi Light Industry Machinery Co., Ltd. for a purchase
price of approximately $20 million, subject to adjustment. This acquisition is
expected to close in the second quarter of 2006 and we plan to finance the
acquisition through a combination of cash and borrowings. The completion of the
acquisition is subject to a number of conditions and there is no assurance that
the acquisition will be completed.

        The forgoing description of the Amendment does not purport to be a
complete statement of the terms and conditions of the Amendment and is qualified
in its entirety by reference to the full text of the Amendment filed with this
report as Exhibit 99.1.

                     time to time parties thereto, the several lenders from time
                     to time parties thereto, and JPMorgan Chase Bank, N.A., as
                     Administrative Agent.
