Item 1.01  Entry into a Material Definitive Agreement.

On April 7, 2005, Kadant Inc., a Delaware corporation ("Kadant"), entered into a
Purchase Agreement (the "Purchase Agreement") with Johnson Acquisition Corp., a
Michigan corporation and a wholly-owned subsidiary of the Buyer, The Johnson
Corporation, a Michigan corporation ("Johnson"), and the principal shareholders
of Johnson identified in the Purchase Agreement to acquire Johnson for
approximately $102 million in cash (the "Base Purchase Price"), subject to a
post-closing adjustment. The parties have also agreed in the Purchase Agreement
to an earn-out provision, based on the achievement of certain revenue targets
over a period of 12 to 15 months following the closing, which could increase the
Base Purchase Price by up to $8 million. In addition to the cash consideration,
Kadant will issue a letter of credit to the sellers for approximately $4
million, subject to adjustment, related to certain expected tax assets of
Johnson, the value of which is expected to be realized by Kadant.

Pursuant to the Purchase Agreement, at the closing $12.75 million of the Base
Purchase Price will be deposited into an escrow fund to secure certain
indemnification obligations of the sellers and to satisfy certain obligations of
the sellers to adjust the Base Purchase Price. On the 18th month anniversary of
the closing, the balance of the escrow fund in excess of $2 million and amounts
held for unresolved claims will be distributed to the sellers. The remainder of
the escrow fund will be held until the fifth anniversary of the closing to
satisfy certain tax, environmental, and other indemnity claims.

The closing of the acquisition contemplated by the Purchase Agreement is subject
to customary closing conditions, including regulatory approvals and the approval
of Johnson's stockholders, as well as Kadant securing at least $55 million in
financing. Kadant is currently negotiating a credit facility of $85 million,
including a $25 million revolver, to finance a portion of the purchase price.
The closing is expected to occur in the second quarter of 2005.

The forgoing description of the transaction contemplated by the Purchase
Agreement does not purport to be a complete statement of the parties' rights
under the Purchase Agreement and is qualified in its entirety by reference to
the full text of the Purchase Agreement which is filed with this report as
Exhibit 99.2. A copy of the press release announcing the execution of the
Purchase Agreement is filed with this report as Exhibit 99.1.
