                    Kadant to Acquire The Johnson Corporation
         Extends Paper Industry Offerings, Brings Access to New Markets

   Company to Host Conference Call on Friday, April 8, 2005, at 8:30 a.m. EDT

ACTON, Mass., April 7, 2005 - Kadant Inc. (NYSE:KAI) announced that it has
entered into a definitive agreement to acquire The Johnson Corporation for
approximately $102 million in cash, subject to a post-closing adjustment. The
parties have also agreed 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 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
benefits of Johnson, the value of which is expected to be realized by Kadant.

         Kadant is currently negotiating a credit facility of $85 million,
including a $25 million revolver, to finance a portion of the purchase price.
The completion of the acquisition 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. The closing is
expected to occur in the second quarter of 2005.

         Kadant expects the acquisition to be accretive to GAAP earnings per
share (EPS) in 2005 by $.05 to $.07, and by approximately $.25 in 2006.

         Johnson is the leading supplier of steam and condensate systems,
hardware, and controls used in the dryer section of paper production. The
company is privately held, with estimated 2004 revenues of $76 million and
estimated adjusted EBITDA margins of 15 to 17 percent based on December 31,
2004, unaudited financial statements provided by Johnson. Johnson's primary
products include rotary joints, syphons, and related steam and condensate
systems. The rotary joints act as seals that connect rotating components with
fixed piping to convey steam, water, air, or heat transfer oils. These products
are used to optimize drying in the paper industry, and also have applications in
industrial cylinder heating and cooling processes in machine tool, plastics,
rubber, steel, and textile production.

         Johnson is based in Three Rivers, Michigan, USA, and has approximately
575 employees at operations in North and South America, Europe, and Asia. The
Three Rivers facility includes a world-class R&D center that features two
commercial-size paper drying cylinders for conducting product research and
customer trials, and extensive joint and seal testing capabilities. Johnson has
been in business for more than 70 years.

         "The agreement to acquire Johnson marks the culmination of our search
for a company that could extend our technology-based offerings in the paper
industry," said William A. Rainville, chairman and chief executive officer of
Kadant. "We are excited about adding Johnson's premier brand to our family of
high-end products. Like Kadant, Johnson's products and services add high value
at critical points in the papermaking process, for relatively low cost. Johnson
not only offers complementary products, a large aftermarket business, and
expanded market coverage, but also shares Kadant's long history of innovation
and leadership as a paper industry supplier. In addition, through its ties to
other industries, I believe Johnson will allow us to apply our technologies to a
number of growth opportunities in new markets."

Use of Non-GAAP Financial Measures
In addition to the financial measures prepared in accordance with generally
accepted accounting principles (GAAP), we use certain non-GAAP financial
measures, including EBITDA.

         EBITDA and EBITDA margins are widely used in the industry as a measure
for evaluating market value. EBITDA is not a measure of performance under GAAP
and should not be considered a substitute for net income as a measure of
performance, nor as a substitute for cash flow as a measure of liquidity. EBITDA
is defined as net income before interest, income taxes, depreciation, and
amortization. Adjusted EBITDA excludes certain estimated non-recurring and
transaction-related expenses. Adjusted EBITDA margin is defined as adjusted
EBITDA divided by revenues. Kadant believes that adjusted EBITDA margin is a
useful measure of Johnson's ability to generate cash flows from operations and
can be used in addition to GAAP financial measures to evaluate company
performance.

         Kadant's guidance relating to the expected impact that the acquisition
will have on its earnings per share is subject to adjustments required under
purchase accounting, such as the determination of the portion of the purchase
price attributable to identifiable intangible assets and the amortization of
those assets.

         Kadant Inc. is a leading global supplier of a range of products that
improve quality and productivity in pulp and paper production, including
stock-preparation equipment, water-management systems, and paper machine
accessories. Kadant, based in Acton, Massachusetts, had approximately $195
million in revenues from continuing operations in 2004 and 950 employees
worldwide. For more information, please visit www.kadant.com.
