Item 7.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations
         -----------------------------------------------------------------------

       Throughout this Management's Discussion and Analysis of Financial
Condition and Results of Operations, we make forward-looking statements, which
are statements concerning possible or assumed future results of operations. When
we use words such as "believes," "expects," "anticipates," "intends," "plans,"
"estimates," "should," "likely," "will," or similar expressions, we are making
forward-looking statements. Forward-looking statements are not guarantees of
performance. They involve risks, uncertainties, and assumptions and are based on
the beliefs and assumptions of our management, based on information currently
available to our management. Our future results of operations may differ
materially from those expressed in the forward-looking statements. Many of the
important factors that will determine these results and values are beyond our
ability to control or predict. You should not put undue reliance on any
forward-looking statements. For a discussion of important factors that may cause
our actual results to differ materially from those suggested by the
forward-looking statements, you should read carefully the section captioned
"Forward-looking Statements' immediately following this Management's Discussion
and Analysis of Financial Condition and Results of Operations.

Overview
--------------------------------------------------------------------------------

Industry Background
       Kadant operates in two segments: the Pulp and Papermaking Equipment and
Systems (Papermaking Equipment) segment and the Composite and Fiber-based
Products segment. Through our Pulp and Papermaking Equipment and Systems
segment, we develop, manufacture, and market a range of equipment and products
for the domestic and international papermaking and paper recycling industries.
Our principal products include custom-engineered systems and equipment for the
preparation of wastepaper for conversion into recycled paper; accessory
equipment and related consumables important to the efficient operation of
papermaking machines; and water-management systems essential for draining,
purifying, and recycling process water. We have been in operation for more than
100 years and have a large, stable customer base that includes most paper
manufacturers in the world. We also have one of the largest installed bases of
equipment in the pulp and paper industry, which provides us with a higher-margin
spare parts and consumables business, which we believe is less susceptible to
the cyclical trends in the paper industry.
       Through the Composite and Fiber-based Products segment, we develop,
manufacture, and market fiber-based composite products for the building
industry, and manufacture and sell agricultural carriers derived from cellulose
fiber.
       Prior to our incorporation, we operated as a division of Thermo Electron
Corporation. We were incorporated in Delaware in November 1991 as a wholly owned
subsidiary of Thermo Electron. In November 1992, we conducted an initial public
offering of our common stock and became a majority-owned public subsidiary of
Thermo Electron. On July 12, 2001, we changed our name from Thermo Fibertek Inc.
to Kadant Inc., and on August 8, 2001, we were spun off from Thermo Electron and
became a fully independent public company (Note 1).

Pulp and Papermaking Equipment and Systems Segment
       Our Papermaking Equipment segment designs and manufactures
stock-preparation equipment, paper machine accessories and water-management
systems for the paper and paper recycling industries. Principal products
manufactured by this segment include:

       - custom-engineered systems and equipment for the preparation of
         wastepaper for conversion into recycled paper;
       - accessory equipment and related consumables important to the efficient
         operation of papermaking machines; and
       - water-management systems essential for the continuous cleaning of
         papermaking machine fabrics and the draining, purifying and recycling
         of process water for paper sheet and web formation.

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

Overview (continued)
--------------------------------------------------------------------------------

Composite and Fiber-based Products Segment
       Our Composite and Fiber-based Products segment consists of two product
lines: our fiber-based granular products and our composite building products. We
employ patented technology to produce biodegradable absorbing granules from
papermaking byproducts. These granules are primarily used as agricultural
carriers. In our composite building products business, we develop, produce, and
market fiber-based composite products, primarily for the building industry, used
for applications such as decking and roof tiles.
       In January 2001, we acquired the remaining 49% equity interest that we
did not already own in Kadant Composites Inc. (formerly named NEXT Fiber
Products Inc.), which is responsible for our composite building products
business (Note 3). We established a composite building products manufacturing
facility in Green Bay, Wisconsin, and began production at the facility in 2000.
       Prior to September 2000, this segment owned and operated a plant that
provided water-clarification and fiber-recovery services to a host mill on a
long-term contract basis. The plant, which we began operating in July 1998,
cleaned and recycled water and long fiber for reuse in the papermaking process.
We sold this plant to the host mill in September 2000 (Note 4).

International Sales
       During 2001, approximately 55% of our sales were to customers outside the
United States, principally in Europe. We generally seek to charge our customers
in the same currency in which our operating costs are incurred. However, our
financial performance and competitive position can be affected by currency
exchange rate fluctuations affecting the relationship between the U.S. dollar
and foreign currencies. We reduce our exposure to currency fluctuations through
the use of forward currency exchange contracts. We may enter into forward
contracts to hedge certain firm purchase and sale commitments denominated in
currencies other than our subsidiaries' functional currencies. These contracts
hedge transactions principally denominated in U.S. dollars.

Critical Accounting Policies
       The discussion and analysis of our financial condition and results of
operations are based upon our consolidated financial statements, which have been
prepared in accordance with accounting principles generally accepted in the
United States. The preparation of these financial statements requires us to make
estimates and assumptions that affect the reported amount of assets and
liabilities, disclosure of contingent assets and liabilities at the date of our
financial statements, and the reported amounts of revenues and expenses during
the reporting period. Actual results may differ from these estimates under
different assumptions or conditions.
       Critical accounting policies are defined as those that are reflective of
significant judgments and uncertainties, and could potentially result in
materially different results under different assumptions and conditions. We
believe that our most critical accounting policies upon which our financial
condition depends, and which involve the most complex or subjective decisions or
assessments, are those described below. For a discussion on the application of
these and other accounting policies, see Note 1 in the notes to consolidated
financial statements.

       Revenue Recognition. Prior to 2000, we generally recognized revenues upon
shipment of our products. During the fourth quarter of 2000, effective as of
January 2, 2000, we adopted Securities and Exchange Commission (SEC) Staff
Accounting Bulletin (SAB) No. 101, "Revenue Recognition in Financial Statements"
(Note 17). In addition, we recognize revenues and profits on certain long-term
contracts using the percentage-of-completion method of accounting.
       - SAB No. 101.  Under SAB No. 101, revenues for products that are sold
         subject to customer acceptance provisions for which compliance with
         those provisions cannot be demonstrated until a point in time
         subsequent to shipment are recognized upon customer acceptance.
         Revenues for products that are sold subject to installation for which
         the installation is essential to functionality or not deemed
         inconsequential or

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

Overview (continued)
--------------------------------------------------------------------------------

         perfunctory are recognized upon completion of installation. Revenues
         for products where installation is not essential to functionality, and
         is deemed inconsequential or perfunctory, are recognized upon shipment
         with estimated installation costs accrued. We provide a reserve for the
         estimated warranty and installation costs at the time revenue is
         recognized. The complexity of all issues related to the assumptions,
         risks, and uncertainties inherent in the application of SAB No. 101
         affect the amounts reported in our financial statements. Under SAB No.
         101, we cannot reliably predict future revenues and profitability due
         to the difficulty of estimating when installation will be performed or
         when we will meet the contractually agreed upon performance tests,
         which can delay or prohibit recognition of revenues. The determination
         of when we install the equipment or fulfill the performance guarantees
         is largely dependent on the customer, their willingness to allow
         installation of the equipment or perform the appropriate tests in a
         timely manner, and their cooperation in addressing possible problems
         impeding achievement of the performance guarantee criteria. Unexpected
         changes in the timing related to the completion of installation or
         performance guarantees could cause our revenue and earnings to be
         significantly affected.

       - Percentage-of-Completion. Revenues recorded under the
         percentage-of-completion method of accounting were $53.5 million in
         2001, $43.4 million in 2000, and $40.7 million in 1999. The percentage
         of completion is determined by comparing the actual costs incurred to
         date to an estimate of total costs to be incurred on each contract. If
         a loss is indicated on any contract in process, a provision is made
         currently for the entire loss. Our contracts generally provide for
         billing of customers upon the attainment of certain milestones
         specified in each contract. Revenues earned on contracts in process in
         excess of billings are classified as unbilled contract costs and fees,
         and amounts billed in excess of revenues are classified as billings in
         excess of contract costs and fees. The complexity of the estimation
         process under the percentage-of-completion method affects the amounts
         reported in our financial statements. A number of internal and external
         factors affect our percentage-of-completion and cost of sales
         estimates, including labor rate and efficiency variances, estimates of
         warranty costs, estimated future material prices from vendors, and
         customer specification and testing requirement changes. In addition, we
         are exposed to the risk, primarily relating to our orders in China,
         that a customer will not comply with the order's contractual
         obligations or not accept delivery of the order, causing such customer
         to forfeit its deposit on the order. The contractual obligations
         relating to the order may be difficult to enforce through a foreign
         country's legal system, which could result in a significant reversal of
         revenue in the period or periods that were affected by the breach of
         contract. Although we make every effort to ensure the accuracy of our
         estimates in the application of this accounting policy, if our business
         conditions were different, or if we used different assumptions, it is
         possible that materially different amounts could be reported in our
         financial statements.

       Accounts Receivable. Judgments are used in determining our allowance for
bad debts and are based on our historical collection experience, current trends,
credit policy, specific customer collection issues, and a percentage of our
accounts receivable arrived at by evaluating each aging category. In determining
these percentages, we look at historical writeoffs of our receivables. We also
look at current trends in the credit quality of our customer base as well as
changes in our credit policies. We perform ongoing credit evaluations of our
customers and adjust credit limits based upon payment history and each
customer's current creditworthiness. We continuously monitor collections and
payments from our customers. While actual bad debts have historically been
within our expectations and the provisions established, we cannot guarantee that
we will continue to experience the same bad debt rates that we have in the past,
especially in light of the prolonged downcycle in the paper industry as
evidenced by an increase in the amount of accounts receivable written off in
2001. A significant change in the liquidity or financial position of any of our
customers could result in the uncollectibility of the related accounts
receivable and could adversely impact our operating cash flows in that period.

                  Financial Condition and Results of Operations

Overview (continued)
--------------------------------------------------------------------------------

       Inventories. We value our inventory at the lower of the actual cost (on a
first-in, first-out, or weighted average basis) or market value and include
materials, labor, and manufacturing overhead. We regularly review inventory
quantities on hand and compare these amounts to historical and forecasted usage
and demand of each particular product or product line. We record a charge to
cost of revenues for excess and obsolete inventory to reduce the carrying value
of the inventories to net realizable value. A significant decrease in demand
could result in an increase in the amount of excess inventory quantities on
hand, resulting in a charge for the write-down of that inventory in that period.
In addition, our estimates of future product usage or demand may prove to be
inaccurate, resulting in an understated or overstated provision for excess and
obsolete inventory. Therefore, although we make every effort to ensure the
accuracy of our forecasts of future product usage and demand, any significant
unanticipated changes in demand or technological developments could have a
significant impact on the value of our inventory and our reported operating
results.

       Warranties. We offer warranties of various durations to our customers
depending upon the specific product and terms of the customer purchase
agreement. We typically negotiate terms regarding warranty coverage and length
of warranty depending on the product and the application. Our standard
mechanical warranties require us to repair or replace defective product during
the warranty period at no cost to the customer. We record an estimate for
warranty related costs at the time of sale based on our actual historical return
rates and repair costs. While our warranty costs have historically been within
our expectations and the provisions established, we cannot guarantee that we
will continue to experience the same warranty return rates or repair costs that
we have in the past. A significant increase in warranty return rates or costs to
repair our products could have a material adverse impact on our operating
results for the period or periods in which such returns or additional costs
materialize.

       Valuation of intangible assets and goodwill. Through year-end 2001, we
assessed the future useful lives and recoverability of these assets whenever
events or changes in circumstances indicated that the current useful lives had
diminished or their carrying value had been impaired. Factors we considered
important which could have triggered an impairment review included the
following:
       - significant underperformance relative to historical or projected future
         operating results;
       - significant changes in the manner of our use of the acquired assets or
         the strategy for our overall business;
       - significant negative industry or economic trends;
We considered the future undiscounted cash flows of acquired companies in
assessing the recoverability of these assets. We assessed cash flows before
interest charges and if impairment was indicated, we would write the asset down
to fair value. If quoted market values were not available, we would estimate
fair value by calculating the present value of future cash flows. If impairment
had occurred, any excess of carrying value over fair value would have been
recorded as a loss. Net intangible assets and goodwill amounted to $123.1
million as of December 29, 2001.
       In July 2001, the Financial Accounting Standards Board (FASB) released
for issuance Statement of Financial Accounting Standards (SFAS) No. 141,
"Business Combinations" and SFAS No. 142, "Goodwill and Other Intangible
Assets." SFAS No. 141 requires the use of the purchase method of accounting and
prohibits the use of the pooling-of-interests method of accounting for business
combinations initiated after June 30, 2001. SFAS No. 141 also requires that we
recognize acquired intangible assets apart from goodwill if the acquired
intangible assets meet certain criteria. It also requires, upon adoption of SFAS
No. 142, that we reclassify the carrying amounts of intangible assets and
goodwill based on the criteria in SFAS No. 141. SFAS No. 142 requires, among
other things, that we no longer amortize goodwill, but instead test goodwill for
impairment at least annually. In addition, SFAS No. 142 requires that we
identify reporting units for the purpose of assessing potential future
impairments of goodwill, reassess the useful lives of other existing recognized
intangible assets, and cease amortization of intangible assets with an
indefinite useful

life. An intangible asset with an indefinite useful life is to be tested for
impairment in accordance with the guidelines in SFAS No. 142. SFAS No. 142 is
required to be applied in fiscal years beginning after December 15, 2001, to all
goodwill and other intangible assets recorded at that date, regardless of when
those assets were initially recognized. SFAS No. 142 requires that we complete a
transitional goodwill impairment test within six months from the date of
adoption. We are also required to reassess the useful lives of other intangible
assets within the first interim quarter after adoption of SFAS No. 142.
Amortization of goodwill in 2001 was $3.4 million on a pretax basis, and $2.3
million on an after-tax basis, or approximately $.19 per diluted share. We are
evaluating the impact of the new impairment standards and have not yet
determined the effect, if any, of adoption on our financial statements.
       Our judgments and assumptions regarding the determination of the fair
value of an intangible asset or goodwill associated with an acquired business
could change as future events impact such fair values. Any future impairment
loss could have a material adverse impact on our financial condition and results
of operations in the period in which impairment is determined to exist.

Industry and Business Outlook
       Our products are primarily sold to the pulp and paper industry. The paper
industry is currently in a prolonged downcycle, characterized by falling pulp
and paper prices, decreased capital spending, and consolidation of paper
companies within the industry. As paper companies continue to consolidate, they
frequently reduce capacity and postpone or even cancel capacity addition or
expansion projects. This trend, along with paper companies' actions to quickly
reduce operating rates and restrict capital spending and maintenance programs
when they perceive weakness in their markets, has adversely affected our
business. There has been a significant amount of downtime in the pulp and paper
industry in 2001. This, coupled with weakened conditions in the world economy in
general and the strong U.S. dollar, will continue to produce a weak market
environment and soften demand for our products in the foreseeable future. The
slowdown in the world economy and the paper industry is continuing and
uncertainty continues into 2002 in the markets we serve. In the longer term, we
expect the consolidation in the paper industry and improved capacity management
will improve paper companies' financial performance and, therefore, will be
favorable for both paper companies and their suppliers.
       Bookings in the fourth quarter of 2001 were disappointing in North
America and China, bringing our backlog down to $31 million. Our recycling
business in North America has been particularly affected by the consolidations
in the paper industry and high levels of machine shutdowns. Looking ahead to
2002, we have lowered our previous guidance and estimate earnings for the year
to be $.70 to $.80 per diluted share. We will focus our efforts on attaining a
more favorable product mix that includes higher-margin aftermarket sales,
reducing operating expenses in the Papermaking Equipment segment, and lowering
operating losses in the composite building products business. The earnings
estimate for 2002 includes the favorable effect of ceasing goodwill amortization
of approximately $.19 per diluted share resulting from the adoption of SFAS No.
142, but excludes the possible unfavorable effect of impairment charges
resulting from the adoption of SFAS No. 142 (Note 1). Revenues in 2002 are
expected to be between $185 and $195 million. More specifically, earnings in the
first quarter of 2002 are expected to be $.05 to $.07 per diluted share, on
revenues of $40 to $43 million. In addition, we plan to incur restructuring and
unusual charges in accordance with EITF No. 94-3 of approximately $2.5 million
in the first quarter, primarily relating to severance charges and the writedown
of a facility and its related equipment in our continued effort to improve
profitability and in response to a weak market environment. Although startups
are difficult to forecast, we believe the composite building products business
will generate nearly $1 million in revenues in the first quarter of 2002, and we
expect revenues of $4 to $6 million from this business in 2002.

                  Financial Condition and Results of Operations


Overview (continued)
--------------------------------------------------------------------------------

       In October 2001, we terminated for nonperformance a distributor's
exclusive rights to distribute certain of our composite building products in
exchange for minimum purchase commitments. We are now rebuilding and expanding
our distribution network for composite building products and have begun a
program of advertising in trade magazines, in-store promotions, and exhibiting
at trade and home shows. Most importantly, in the fourth quarter of 2001 and the
first quarter of 2002, we added three distributors with five locations in the
Midwest and Southwest. We believe that the market for composite building
products will grow as consumer awareness of the advantages of these products
increases their acceptance as an alternative to traditional wood products,
especially in light of the phase-out of widely used pressure-treated lumber that
contains potentially harmful chemicals.

       Revenues decreased to $221.2 million in 2001 from $234.9 million in 2000.
Excluding acquisitions and dispositions in 2000 and the unfavorable effects of
currency translation in 2001 of $3.6 million due to a stronger U.S. dollar
relative to other currencies in countries in which we operate, revenues in 2001
decreased by $9.9 million.
       Pulp and Papermaking Equipment and Systems Segment. Excluding the results
of an acquisition and the effect of currency translation, revenues in our
Papermaking Equipment segment decreased $10.8 million, or 5%. Revenues from the
segment's accessories and water-management product lines decreased $5.6 million
and $4.2 million, respectively, primarily as a result of a decrease in demand in
North America due to adverse market conditions. Revenues from the Papermaking
Equipment segment's stock-preparation equipment product line decreased $0.7
million primarily as a result of a decrease in sales in North America, largely
offset by increases in sales in Europe and export sales to China.
       Composite and Fiber-based Products Segment. The Composite and Fiber-based
Products segment revenues decreased $0.1 million, primarily due to a $1.0
million decrease in revenues as a result of the sale of the fiber-recovery and
water-clarification services plant in September 2000, and to a lesser extent, a
$0.8 million decrease in revenues at its fiber-based products business primarily
due to a decrease in demand from two of its largest agricultural carrier
customers. These decreases were largely offset by a $1.7 million increase in
sales from its composite building products.

Gross Profit Margin
       Gross profit margin decreased to 37% in 2001 from 38% in 2000. The gross
profit margin increased slightly to 39.0% in 2001 from 38.7% in 2000 at the
Papermaking Equipment segment. The gross profit margin decreased at the
Composite and Fiber-based Products segment due to an increase of approximately
$0.7 million in the cost of natural gas used in the production of fiber-based
granules and, to a lesser extent, underabsorbed manufacturing overhead as a
result of lower revenues and production at the granules business in 2001. In
addition, the gross margin decreased in this segment due to increased negative
gross margins as a result of startup efforts at its composite building products
business and the absence in 2001 of higher-margin revenues from the
fiber-recovery and water-clarification services plant.

Other Operating Expenses
       Selling, general, and administrative expenses as a percentage of revenues
increased slightly to 27% in 2001 from 26% in 2000 due to the decrease in
revenues. Selling, general, and administrative expenses decreased to $59.0
million in 2001 from $60.9 million in 2000 primarily due to the effects of
foreign currency translation and cost reduction efforts at the Papermaking
Equipment segment.

Kadant Inc.                                            2001 Financial Statements

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations


2001 Compared With 2000 (continued)
       Research and development expenses decreased to $6.6 million in 2001
compared with $7.7 million in 2000, primarily at the Papermaking Equipment
segment. Research and development expenses as a percentage of revenues remained
constant at 3% in both periods.

Restructuring Costs
       During 2001, we recorded restructuring costs of $0.7 million for
severance costs relating to 63 employees primarily in manufacturing and sales
functions at the Papermaking Equipment segment's domestic subsidiaries, all of
whom were terminated by December 29, 2001. These actions were taken in an effort
to improve profitability and were in response to a continued weak market
environment (Note 12).

Gain on Sale of Business and Property
       In September 2000, we sold our fiber-recovery and water-clarification
services plant for $3.6 million, resulting in a pretax gain of $0.7 million
(Note 4). In June 2000, we sold our interest in a tissue mill for $3.9 million
in cash, resulting in a pretax gain of $1.0 million (Note 4).

Operating Income
       Operating income decreased to $16.5 million in 2001 from $23.4 million in
2000. Excluding restructuring items in both periods, operating income decreased
7% to $26.7 million in 2001 from $28.7 million in 2000 at the Papermaking
Equipment segment. Excluding restructuring costs in 2001 and gain on sale of
property in 2000, operating losses increased to $5.9 million in 2001 from $3.8
million in 2000 at the Composite and Fiber-based Products segment. Operating
losses from the composite building products business were $4.1 million and $2.4
million in 2001 and 2000, respectively.

Interest Income and Expense
       Interest income decreased to $6.6 million in 2001 from $10.5 million in
2000. Of the total decrease in interest income in 2001, approximately $2.4
million was due to lower prevailing interest rates, and $1.4 million was due to
lower average invested balances. The decrease in average invested balances
primarily related to Thermo Fibergen's 2001 and 2000 common stock redemption
payments (Note 11), and to a lesser extent, the repurchases of our subordinated
convertible debentures in the fourth quarter of 2001 (Note 8). Interest expense
decreased slightly to $7.3 million in 2001 from $7.5 million in 2000, primarily
as a result of the repurchase of our subordinated convertible debentures in 2001
(Note 8).

Income Taxes
       The effective tax rate was 42% in 2001 and 41% in 2000. The effective tax
rates exceeded the statutory federal income tax rate primarily due to the impact
of state income taxes and nondeductible expenses. We expect the effective tax
rate to be in the range of 37% to 39% in 2002 as a result of no longer
amortizing goodwill under SFAS No. 142 (Note 1) and various tax planning
initiatives.

Minority Interest
       Minority interest income in 2001 primarily represents the minority
investors' share of losses in our Thermo Fibergen subsidiary. Minority interest
income in 2000 primarily represents the minority investor's share of losses in
Thermo Fibergen's Kadant Composites subsidiary, offset in part by the accretion
of Thermo Fibergen's common stock subject to redemption.

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations


2001 Compared With 2000 (continued)

Extraordinary Item
       During 2001, we repurchased $34.9 million principal amount of our 4 1/2%
subordinated convertible debentures for $33.5 million in cash, resulting in an
extraordinary gain of $0.6 million, net of deferred debt charges and net of
income tax provision of $0.4 million (Note 8).

Cumulative Effect of Change in Accounting Principle
       In accordance with the requirements of SAB No. 101, "Revenue Recognition
in Financial Statements," we adopted the pronouncement as of January 2, 2000,
and recorded a charge in the first quarter of 2000 representing the cumulative
effect of change in accounting principle of $0.9 million, net of income tax
benefit of $0.6 million (Note 17).

Contingency
       In 2001, Sequa Corporation made a claim in arbitration against us for
$3.5 million for an alleged breach of contract following Sequa's purchase of the
stock of our subsidiary, Thermo Wisconsin Inc., in February 1999. In December
2001, we were notified by the arbitrator that we had prevailed in the case and
were also awarded attorney's fees and expenses incurred in our defense, which
were paid to us in January 2002.

2000 Compared With 1999

Revenues
       Excluding the results of Thermo Wisconsin, which was sold in February
1999, revenues increased to $234.9 million in 2000 from $226.3 million in 1999.
Thermo Wisconsin's revenues from external customers were $1.8 million in 1999.
Gauld Equipment and Cyclotech, which were acquired in 2000 (Note 4), added
revenues of $4.6 million during 2000. The inclusion for the full 2000 period of
results from Arcline Products, which was acquired in May 1999, added incremental
revenues of $0.8 million. The unfavorable effects of currency translation due to
the strengthening in value of the U.S. dollar relative to other currencies in
countries in which we operate decreased revenues at the Papermaking Equipment
segment by $9.2 million in 2000.
       Pulp and Papermaking Equipment and Systems Segment. Excluding the results
of acquisitions and the effect of currency translation, revenues in our
Papermaking Equipment segment increased $13.2 million, or 6%. Revenues from the
segment's stock-preparation equipment product line increased $15.2 million as a
result of a $15.7 million increase in sales by the North American operations,
due principally to greater demand, offset slightly by a decrease in sales in
Europe, due to the general market weakness. Revenues from the Papermaking
Equipment segment's accessories product line decreased $1.9 million as a result
of a decrease in demand in North America and Europe. Revenues from the segment's
water management product line increased $0.3 million related to increased demand
in Europe, largely offset by a decrease in demand in North America.
       Composite and Fiber-based Products Segment. Our Composite and Fiber-based
Products segment revenues decreased $0.8 million, primarily due to decreased
demand for fiber-based products from the segment's largest customer, as well as
a $0.4 million decrease as a result of the sale of the fiber-recovery and
water-clarification services plant in September 2000 (Note 4).

Gross Profit Margin
       Gross profit margin decreased to 38% in 2000 from 41% in 1999. The gross
profit margin decreased at the Papermaking Equipment segment, primarily due to a
change in product mix that resulted largely from a higher proportion of
lower-margin large system sales at our North American stock-preparation
equipment business. To a

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

2000 Compared With 1999 (continued)
lesser extent, the gross profit margin decreased at the Composite and
Fiber-based Products segment, primarily due to decreased sales without a
corresponding decrease in costs, an increase of approximately $0.6 million in
the cost of natural gas in 2000, and the inclusion of $0.6 million of overhead
costs at our new composite building products business.

Other Operating Expenses
       Selling, general, and administrative expenses as a percentage of revenues
decreased to 26% in 2000 from 27% in 1999, primarily due to increased revenues
from our Papermaking Equipment segment's stock-preparation equipment product
line.
       Research and development expenses increased slightly to $7.7 million in
2000, compared with $7.3 million in 1999, or 3% of revenues in both periods. The
increase in research and development expenses in 2000 primarily represents
increased expenditures at the Papermaking Equipment segment.

Gain on Sale of Business and Property
       In September 2000, we sold our fiber-recovery and water-clarification
services plant for $3.6 million, resulting in a pretax gain of $0.7 million
(Note 4). In June 2000, we sold our interest in a tissue mill for $3.9 million
in cash, resulting in a pretax gain of $1.0 million (Note 4). In February 1999,
we sold our Thermo Wisconsin subsidiary for $13.6 million in cash, resulting in
a pretax gain of $11.2 million (Note 4).

Restructuring and Unusual Items
       Restructuring and unusual income of $0.5 million in 2000 represents the
reversal of a charge taken in 1999 related to the termination of a distributor
agreement, which we are no longer obligated to pay due to the breach of the
agreement by the third party distributor (Note 12). Restructuring and unusual
costs of $6.2 million in 1999 represents write-downs for impairment of assets,
severance costs, termination of distributor agreements, the expected settlement
of a contractual dispute, and facility-closure costs (Note 12).

Operating Income
       Operating income decreased to $23.4 million in 2000 from $29.5 million in
1999. Excluding restructuring and unusual items in both periods, operating
income decreased 14% to $28.7 million in 2000 from $33.2 million in 1999 at the
Papermaking Equipment segment. Excluding gain on sale of property in 2000,
operating losses increased to $3.8 million in 2000 from $1.0 million in 1999 at
the Composite and Fiber-based Products segment. Operating losses from the
composite building products business were $2.4 million and $0.2 million in 2000
and 1999, respectively.

Interest Income and Expense
       Interest income increased to $10.5 million in 2000 from $8.5 million in
1999, due to higher average invested balances and, to a lesser extent, higher
interest rates. Interest expense was relatively unchanged at $7.5 million in
2000 and $7.4 million in 1999.

Income Taxes
       The effective tax rate was 41% in 2000, compared with 39% in 1999. The
effective tax rate exceeded the statutory federal income tax rate primarily due
to the impact of state income taxes and nondeductible expenses. The effective
tax rate increased in 2000 as a result of an increase in nondeductible and other
expenses.

                  Financial Condition and Results of Operations

2000 Compared With 1999 (continued)

Minority Interest
       Minority interest income in 2000 primarily represents the minority
investor's share of losses in Thermo Fibergen's Kadant Composites subsidiary for
the full year, offset in part by accretion of Thermo Fibergen's common stock
subject to redemption. As of September 30, 2000, Thermo Fibergen's common stock
subject to redemption was fully accreted. In January 2001, Thermo Fibergen
purchased the remaining 49% equity interest in Kadant Composites from the
minority investor. Through Thermo Fibergen's redemption of common stock in
September 2000 (Note 11), our ownership in Thermo Fibergen increased to 91%.
Minority interest expense in 1999 primarily represents accretion of Thermo
Fibergen's common stock subject to redemption, offset in part by the minority
investor's share of losses in Thermo Fibergen's Kadant Composites subsidiary.

Cumulative Effect of Change in Accounting Principle
       In accordance with the requirements of SAB No. 101, "Revenue Recognition
in Financial Statements," we adopted the pronouncement as of January 2, 2000,
and recorded a charge in the first quarter of 2000 representing the cumulative
effect of change in accounting principle of $0.9 million, net of income tax
benefit of $0.6 million (Note 17).

Liquidity and Capital Resources
--------------------------------------------------------------------------------

       Consolidated working capital was $159.4 million at December 29, 2001,
compared with $173.1 million at December 30, 2000. Included in working capital
are cash, cash equivalents, and available-for-sale investments of $119.4 million
at December 29, 2001, compared with $148.6 million at December 30, 2000. In
addition, we had $5.7 million invested in an advance to a former affiliate as of
December 30, 2000. Of the total cash, cash equivalents, and available-for-sale
investments at December 29, 2001, $7.5 million was held by our majority-owned
Fiberprep Inc. subsidiary, and the remainder was held by us and our wholly owned
subsidiaries. At December 29, 2001, $50.8 million of our cash, cash equivalents,
and available-for-sale investments was held by our foreign subsidiaries.
       During 2001, cash of $12.8 million was provided by operating activities
compared with $18.4 million in 2000. A decrease in accounts receivable provided
cash of $3.2 million, primarily at the Papermaking Equipment segment due to
improved collection efforts, the timing of payments, and our overall decrease in
revenues. Cash of $2.2 million was used by an increase in unbilled contract
costs and fees due to the timing of billings at the Papermaking Equipment
segment. In addition, an increase in inventories, primarily at the Papermaking
Equipment segment, used cash of $0.8 million related to an increase in work in
process inventories. A decrease in accounts payable used cash of $2.9 million
primarily in the Papermaking Equipment segment due to the timing of payments. In
addition, a use of cash of $4.6 million resulted from a decrease in other
accrued liabilities, primarily customer deposits, deferred revenues, and accrued
income taxes.
       Our investing activities, excluding available-for-sale investments and
advances to former affiliates activity, used $3.8 million of cash in 2001,
compared with $6.0 million in 2000. During 2001, we purchased property, plant,
and equipment for $4.6 million, including $3.0 million at the Composite and
Fiber-based Products segment, the effects of which were offset in part by the
collection of $2.4 million from a note receivable related to the September 2000
sale of our fiber-recovery and water-clarification services plant. In 2001, we
paid $1.8 million in connection with the acquisition of shares of Thermo
Fibergen's common stock, and an additional $1.4 million in 2002 in connection
with this transaction (Note 11).

                  Financial Condition and Results of Operations

Liquidity and Capital Resources (continued)
--------------------------------------------------------------------------------

       Our financing activities used cash of $43.8 million in 2001, compared
with $33.7 million in 2000. During 2001, we used $33.4 million and $0.6 million
to fund the repurchase of our subordinated convertible debentures and common
stock, respectively, as well as $0.5 million to fund the payment of long-term
obligations. These uses of cash were offset in part by $2.6 million of cash
provided by the issuance of our common stock and subsidiary common stock through
the exercise of stock options. In September 2001, our board of directors
authorized the repurchase, through September 24, 2002, of up to $50 million of
our debt and equity securities in the open market, or in negotiated
transactions. As of December 29, 2001, we had $15.9 million remaining under this
authorization. In addition, during the third quarter of 2001, cash of $1.3
million was provided by a transfer of cash and an associated liability from
Thermo Electron in connection with the spinoff.
       In 2000, during the initial redemption period, holders of Thermo
Fibergen's common stock and common stock redemption rights surrendered 2,713,951
shares of Thermo Fibergen's common stock at a redemption price of $12.75 per
share, for a total of $34.6 million. Thermo Fibergen used available working
capital to fund the payment and retired these shares immediately following the
redemption. In 2001, during the final redemption period, holders of Thermo
Fibergen's common stock and common stock redemption rights surrendered 1,030,562
shares of Thermo Fibergen's common stock at a redemption price of $12.75 per
share, for a total of $13.1 million. Common stock redemption rights amounting to
970,487 were not surrendered for redemption by the end of the redemption period
and expired. Thermo Fibergen used a combination of available working capital and
a $6,000,000 loan from us to fund the redemption payment. Immediately following
the final redemption period, 10,522,087 shares of Thermo Fibergen common stock
remained outstanding, including 10,407,600 shares held by us and 114,487 shares
held by shareholders other than us. In January 2002, we paid $1.4 million to the
shareholders of the 114,487 shares of Thermo Fibergen's common stock as part of
the Thermo Fibergen merger transaction (Note 11).
       At December 29, 2001, we had $80.4 million of undistributed foreign
earnings that could be subject to tax if remitted to the U.S. We do not
currently intend to repatriate undistributed foreign earnings into the U.S. We
believe that any additional U.S. tax liability due upon remittance of such
earnings would be immaterial due to available U.S. foreign tax credits.
       In compliance with the IRS ruling on the spinoff, we intend to issue
equity in the range of 10 to 20 percent of our outstanding common stock within
one year of the spinoff to support our current business plan, which includes
repayments of debt, acquisitions, creation of strategic partnerships, and
investments in our core papermaking equipment business and composite building
products business (Note 1).
       Our net debt (calculated as total short- and long-term debt and common
stock of subsidiary subject to redemption, less cash, cash equivalents, advance
to a former affiliate, and available-for-sale investments) was $0.4 million at
December 29, 2001, compared with $17.9 million at December 30, 2000.
       During 2002, we plan to make expenditures for property, plant, and
equipment of approximately $3.0 million. Included in this amount is $0.7 million
for Kadant Composites, which intends to make capital expenditures to develop and
expand its composite building products business. Our ability to use our cash and
to incur additional debt is limited by financial covenants in our distribution
agreement with Thermo Electron (Note 9). These financial covenants, as amended,
require that (1) the ratio of our net indebtedness to net capitalization not
exceed 40% and (2) on a rolling four quarter basis, that the sum of our (a)
operating income (excluding restructuring and other unusual items, such as gains
on sales of assets, included in operating income), (b) amortization of goodwill
and other intangible assets, and (c) interest income, be at least four times
greater than interest expense. At the end of December 2001, we would not have
been in compliance with the second covenant. The agreement was subsequently
amended to provide that in instances where our net indebtedness to net
capitalization is less than or equal to 20% for any measurement date, the
coverage ratio of four times greater than interest expense is lowered to three
times greater than interest expense. As of December 29, 2001, we were in
compliance with all the financial covenants of the agreement, as amended.

our contractual obligations and commercial commitments in a single location.
Detailed information concerning these obligations and commitments can be found

 *  There are no unconditional purchase obligations of significance other than
    inventory and property, plant, and equipment purchases made in the ordinary
    course of business, which are excluded from this analysis.

**  In the ordinary course of business, we are, at times, required to issue
    limited performance guarantees relating to our equipment and systems. We
    typically limit our liability under these guarantees to amounts that would
    not exceed the value of the contract. We believe that we have adequate
    reserves for any potential liability in connection with such guarantees.
    Such guarantees are excluded from this analysis.


       Provisions in financial guarantees or commitments, debt or lease
agreements, or other arrangements could trigger a requirement for an early
payment, additional collateral support, amended terms, or acceleration of
maturity. The guarantee by Thermo Electron on our 4 1/2% subordinated
convertible debentures requires us to comply with certain financial ratios
included in our amended Plan and Agreement of Distribution with Thermo Electron
(Note 9). We are in compliance with these financial covenants, as amended, as of
December 29, 2001, the latest measurement date. If we were unable to comply with
the financial covenants, Thermo Electron could require us to refinance our
debentures, conduct an exchange offer for the debentures, or repay in full the
underlying obligation. If we were required to take these actions, we might not
have sufficient cash or credit capacity to engage in transactions, such as
significant acquisitions, that might otherwise benefit our business. These
circumstances could also impair our ability to continue to engage in
transactions that have been integral to historical operations. We believe that
our existing resources are sufficient to meet the capital requirements of our
existing operations for the foreseeable future.
