                                     PART I

ITEM 1. BUSINESS

        Lufkin Industries, Inc. (the "Company") was incorporated under the laws
of the State of Texas on March 4, 1902, and since that date has maintained its
principal office and manufacturing facilities in Lufkin, Texas. The Company
employed approximately 1,800 people at December 31, 2002, including
approximately 1,200 that were paid on an hourly basis. The Company is divided
into three operating segments: Oil Field, Power Transmission and Trailer.

        OIL FIELD

        Products:

        The Oil Field segment manufactures and services artificial reciprocating
        rod lift equipment, commonly referred to as pumping units, and related
        products.

                Pumping Units- Four basic types of pumping units are
                manufactured: an air-balanced unit; a beam-balanced unit; a
                crank-balanced unit; and a Mark II Unitorque unit. The basic
                differences between the four types relate to the
                counterbalancing system. The depth of a well and the desired
                fluid production determine the type of counterbalancing
                configuration that is required. There are numerous sizes and
                combinations of Lufkin oil field pumping units within the four
                basic types.

                Service- Through a network of service centers, the Company
                transports and repairs pumping units. The service centers also
                refurbish used pumping units.

                Automation- The Company designs, manufactures, installs and
                services computer control equipment and analytical services for
                pumping units that lower production costs and optimize well
                efficiency.

                Foundry Castings- As part of the Company's vertical integration
                strategy, the Oil Field segment operates an iron foundry to
                produce castings for new pumping units. In order to maximize
                utilization of this facility, castings for third parties are
                also produced.

        Markets:

        Demand for pumping unit equipment primarily depends on the level of
        onshore oil well drilling activity as well as the depth and fluid
        conditions of that drilling. Drilling activity is driven by the
        available cash flow of our customers as well as their long-term
        perceptions of the level and stability of the price of oil. Also, the
        availability of used pumping unit equipment impacts the North American
        market.

        Competition:

        The primary global competition for new pumping units and automation
        equipment is Weatherford. Used pumping units are also an important
        factor in the North American market, as customers will generally attempt
        to satisfy requirements through used equipment before purchasing new
        equipment. While the Company believes that it is one of the larger
        manufacturers of sucker rod pumping units in the world, manufacturers of
        other types of units (submersibles and hydraulics) have a significant
        share of the total artificial lift market. While Weatherford is the
        Company's single largest competitor in the service market, small
        independent operators provide significant competitive pressures.

        Because of the competitive nature of the business and the relative age
        of many of the product designs, price, delivery time, product quality
        and customer service are important factors in winning orders. To this
        end, the Company maintains strategic levels of inventories in order to
        ensure delivery times and invests in new capital equipment to maintain
        quality and price levels.

        POWER TRANSMISSION

        Products:

        The Power Transmission segment designs, manufactures and services speed
        increasing and reducing gearboxes for industrial applications. Speed
        increasers convert lower speed and higher torque input to higher speed
        and lower torque output while speed reducers convert higher speed and
        lower torque input to lower speed and higher torque output. The Company
        produces numerous sizes and designs of gearboxes depending on the end
        use. While there are standard designs, the majority of gearboxes are
        customized for each application.

                High-Speed Gearboxes- Gearboxes where rotations per minute (RPM)
                exceed 4,000 and range up to 60,000. These gearboxes require
                extremely high precision manufacturing and testing due to the
                stresses on the gearing. The ratio of increasers to reducers is
                fairly even. These gearboxes more typically service the energy
                related markets of petrochemicals, refineries, offshore drilling
                and transmission of oil and gas.

                Low-Speed Gearboxes- Gearboxes where RPM are below 4,000. The
                majority of low-speed gearboxes are reducers. While still
                requiring close tolerances, these gearboxes do not require the
                same precision of manufacturing and testing. These gearboxes
                more typically service commodity-related industries like rubber,
                sugar, paper, steel, plastics, mining and cement as well as
                marine propulsion.

                Parts- The Company manufactures capital spares for customers in
                conjunction with the production of new gearboxes as well as
                producing parts for after-market service.

                Repair & Service- The Company provides on and off-site repair
                and service for not only its own products but also those
                manufactured by other companies. Repair work is performed in
                dedicated facilities due to the high turn-around times required.

                                        2

        Markets:

        As noted above, Power Transmission services many diverse markets, each
        of which has its own unique set of drivers. Favorable conditions for one
        market may be unfavorable for another market. Generally, if general
        global industrial capacity utilizations are not high, then spending on
        new equipment lags. Also impacting demand are government regulations
        involving safety and environmental issues that can require capital
        spending.

        Competition:

        Despite the highly technical nature of this product, there are many
        competitors. While several North American competitors recently exited
        the market, many European companies remain in the market. They include
        Maag, Flender Graffenstaden, BHS, Renk, Allen Gear and Horsburgh &
        Scott. While price is an important factor, proven designs and
        workmanship are critical factors. Due to this, the Company outsources
        very little of the design and manufacturing processes.

        TRAILER

        Products:

        The Trailer segment manufactures and services various highway trailers
        for the freight-hauling market.

                Vans- General-purpose dry-freight vans. These are the highest
                production trailer in the segment.

                Floats- Flat-bed style trailers used in hauling heavier loads
                that do not require protection from outdoor elements.

                Dumps- Trailers designed to haul bulk materials like gravel or
                sand.

                Service- Through a network of company-owned branches, both
                trailers produced by the Company and by others are repaired and
                serviced.

        Markets:

        The Company primarily sells its products in the United States to small
        and medium size fleet freight-hauling companies. Demand in this market
        is driven by the available cash flow or financing capabilities of the
        industry, age of the trailer fleets, changes in government regulations,
        availability of quality used trailers and the medium-term outlook for
        freight volumes. The profitability of the freight-hauling market is
        driven by freight volumes, fuel prices, wage levels and insurance costs.

        In the last several years, the freight-hauling market has been severely
        depressed due to low freight volumes and higher operating costs. This
        has caused many freight companies to go out of business, which have lead
        to the bankruptcy of several trailer manufacturers.

        Competition:

        The new trailer market is highly competitive with relatively low
        barriers to entry. The majority of the cost of a new trailer comes from
        purchased materials of aluminum, steel, tires, axles and wood flooring.
        Since there is minimal product differentiation in this market, price is
        the key driver. The companies with the highest market share are Great
        Dane and Wabash, along with several other large manufacturers like
        Utility, Fontaine and Hyundai. The Company does not have a significant
        market share in the new trailer market.

ITEM 2. PROPERTIES

        The Company's major manufacturing facilities are located in and near
Lufkin, Texas are owned in fee and include approximately 150 acres, a foundry,
machine shop, structural shops, assembly shops and warehouses. The Company also
has a plant in Nisku, Canada that produces structural parts for pumping units.
These parts are then assembled with parts shipped from Lufkin and are delivered
to the Company's Canadian customers. The Company also has a plant in
Fougerolles, France that manufactures, assembles and sells industrial gears and
power transmission products throughout Europe.

ITEM 3. LEGAL PROCEEDINGS

        A class action complaint was filed in the United States District Court
for the Eastern District of Texas on March 7, 1997, by an employee and a former
employee which alleged race discrimination in employment. Certification hearings
were conducted in Beaumont, Texas in February of 1998 and in Lufkin, Texas in
August of 1998. The District Court in April of 1999 issued a decision that
certified a class for this case, which includes all persons of a certain
minority employed by the Company from March 6, 1994, to the present. The Company
appealed this class certification decision by the District Court to the 5th
Circuit United States Court of Appeals in New Orleans, Louisiana. This appeal
was denied on June 23, 1999. The Company is defending this action vigorously.
Furthermore, the Company believes that the facts and the law in this action
support its position and is confident that it will prevail if this case is tried
on its merits.

        In the case of Echometer and James N. McCoy vs. Lufkin Industries, Inc.,
the plaintiff filed suit in U.S. District Court alleging infringement of a Data
Processing and Display for Echo Sounding Patent. The Company has vigorously
defended its position that its fluid level product does not infringe the
plaintiff's patent. Trial for this case is scheduled for May 2003.

        There are various other claims and legal proceedings arising in the
ordinary course of business pending against or involving the Company wherein
monetary damages are sought. It is management's opinion that the Company's
liability, if any, under such claims or proceedings would not materially affect
its consolidated financial position or results of operations.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

RESULTS OF OPERATIONS

        Sales for the year ended December 31, 2002, decreased to $228.7 million
from $278.9 million for the year ended December 31, 2001. Sales for 2000 were
$254.6 million. The Company reported net earnings of $8.5 million or $1.26 per
share (diluted) for the year ended December 31, 2002, compared to net earnings
of $19.5 million or $3.03 per share (diluted) for the year ended December 31,
2001. Net income of $7.0 million or $1.11 per share (diluted) was reported for
the year ended December 31, 2000.

        In October 2002, the Company experienced a two-week work stoppage by its
unionized workforce at its primary manufacturing facilities in Lufkin, Texas.
This work stoppage was related to health-care and pension benefit differences
during contract negotiations. While certain shipments were delayed during the
fourth quarter of 2002, this work stoppage did not have a significant impact on
the overall results of the fourth quarter of 2002.

The sales mix of the Company's operating segments for the three years ended
December 31, 2002, was as follows:

</TABLE>

        Oil Field sales for the year ended December 31, 2002, decreased 34.9% to
$118.7 million from $182.3 million in the year ended December 31, 2001. Lower
energy prices in the first half of 2002 caused declines in oil field drilling
and production activity, directly impacting the sale of new pumping units. The
higher energy prices seen in the last half of 2002 have not translated into
higher activity levels. Drilling activity has not increased with the higher
energy prices due to uncertainty over both future global demand levels and the
stability of the price of oil. This was also reflected in the backlog of Oil
Field, which declined to $12.6 million at December 31, 2002, from $19.4 million
at December 31, 2001.

        Gross profit for Oil Field decreased to $25.0 million, or 48.9%, for the
year ended December 31, 2002, compared to $48.9 million for the year ended
December 31, 2001, due primarily to the decline in sales of oil field products
but also due to a decline in the gross margin. Gross margin decreased to 21.1%
in 2002 compared to 26.9% in 2001 due to the product mix shifting towards lower
margin commercial castings and fixed production costs increasing as a percentage
of revenue.

        Direct selling, general and administrative expenses for Oil Field
decreased to $7.6 million, or 20.0%, for the year ended December 31, 2002, from
$9.5 million for the year ended December 31, 2001. This decrease was due to
lower third-party sales commissions and lower legal expenses associated with
ongoing and routine litigation. In 2002 certain types of legal expenses
previously charged directly to Oilfield were charged to Corporate.

        Sales for the Company's Power Transmission segment increased to $70.5
million, or 12.7%, for the year ended December 31, 2002, compared to $62.5
million for the year ended December 31, 2001. High-speed applications serving
the oil and gas, refinery and petrochemical markets increased in 2002 with some
improvement seen in low-speed applications for the sugar and marine markets.
However, demand in the power generation, steel and rubber markets continues to
remain weak, contributing to the decline in Power Transmission backlog to $30.9
million as of December 31, 2002, compared to $31.5 million as of December 31,
2001.

                                        5

<PAGE>

        Power Transmission gross profit increased to $19.6 million, or 3.3%, for
the year ended December 31, 2002, from $18.9 million for the year ended December
31, 2001. This improvement did not match the increase in sales, due to a gross
margin decline to 27.8% for the year ended December 31, 2002, from 30.4% for the
year ended December 31, 2001. Higher margins on sales of high-speed gearboxes
and parts were offset by a decline in inter-segment revenue to the Oil Field
segment, reducing from $12.8 million in 2001 to a more normal level of $1.8
million in 2002. Due to the extraordinary demand for pumping units in Oil Field
in 2001, Power Transmission produced a large number of gearboxes for Oil Field.
While these gearboxes were sold near cost to Oil Field, this incremental volume
improved plant utilization and fixed cost absorption of Power Transmission,
improving the overall gross margin.

        Direct selling, general and administrative expenses for Power
Transmission increased slightly to $10.2 million, or 1.0%, for the year ended
December 31, 2002, from $10.1 million for the year ended December 31, 2001.

        Trailer sales for the year ended December 31, 2002, increased 15.9% to
$39.6 million from $34.1 million for the year ended December 31, 2001, due to
some improvement in the freight-hauling market. However, the market remained
depressed due to a combination of lower shipping volumes, higher fuel costs,
higher personnel costs and higher insurance rates. The continued depressed state
of the market is reflected in the decline in backlog from $13.5 million at
December 31, 2001, to $10.1 million at December 31, 2002.

        Trailer gross profit and margin improved to $2.3 million and 5.9%,
respectively, for the year ended December 31, 2002, from $0.2 and 0.7%,
respectively, for the year ended December 31, 2001. This gross margin
improvement was primarily due to two factors: cost containment efforts and
reduced warranty charges. Labor and overhead costs only increased 12.0% in 2002
compared to 2001 versus the 15.9% revenue increase. Warranty charges were lower
due to improved quality efforts and a lower pool of trailers under warranty.

        Direct selling, general and administrative expenses for Trailer
decreased to $1.5 million, or 31.9%, for the year ended December 31, 2002, from
$2.2 million for the year ended December 31, 2001. This decrease was primarily
due to lower insurance claim expenses.

        Corporate administrative expenses, which are allocated to the segments
primarily based on third-party revenues, increased to $14.2 million, or 6.8%,
for the year ended December 31, 2002, from $13.3 million for the year ended
December 31, 2001, due to costs associated with the settlement of the labor
dispute in the fourth quarter of 2002 and higher legal expenses associated with
ongoing and routine litigation.

        Other income and expense for the year ended December 31, 2002, totaled
$0.4 million of income versus $0.7 million of expense for the year ended
December 31, 2001. This improvement was due to higher interest income from
invested cash, lower interest expense from reduced debt levels and the
non-recurrence of losses on asset disposals incurred in 2001.

        Pension income, which is reported as a reduction of cost of sales in
each segment, decreased to $5.3 million, or 10.2%, for the year ended December
31, 2002, from $5.9 million for the year ended December 31, 2001. This decline
was because liabilities of the plan increased while the expected return on
assets declined from a reduction in the fair market value. Pension income in
2003 is expected to decline to approximately $2.5 million due to further
declines in the fair market value of the assets of the plan lowering the
expected return. In conjunction with these market declines, the Company reviewed
its assumptions for 2003 and lowered the discount rate to 6.75% from 7.00%, the
expected long-term return on assets to 8.75% from 9.00% and the compensation
rate increase to 4.50% from 5.00%.

<PAGE>

        Oil Field sales for the year ended December 31, 2001, increased 54.3% to
$182.3 million from $118.1 million in the year ended December 31, 2000.
Increases in production activity among oil producers resulted in significant
increases in both new pumping unit sales and oil field service activity.
However, lower energy prices and corresponding production activity in the fourth
quarter of 2001 is reflected in the backlog of Oil Field, which declined to
$19.4 million at December 31, 2001, from $33.3 million at December 31, 2000.

        Gross profit for Oil Field increased to $48.9 million, or 105.9%, for
the year ended December 31, 2001, compared to $23.7 million for the year ended
December 31, 2000, due to the above noted increases in product volume associated
with higher production activity. Gross margin improved to 26.8% in 2001 compared
to 20.1% in 2000 due primarily to increased leverage on the Company's fixed
costs.

        Direct selling, general and administrative expenses for Oil Field
increased to $9.5 million, or 33.7%, for the year ended December 31, 2001, from
$7.1 million for the year ended December 31, 2000. This increase was due to
higher third-party sales commissions and higher internal sales activity in
conjunction with above noted increase in revenue. Also, administrative expenses
increased due to higher legal expenses associated with ongoing and routine
litigation.

        Sales for the Company's Power Transmission segment decreased slightly to
$62.5 million for the year ended December 31, 2001, compared to $62.9 million
for the year ended December 31, 2000. The uncertain economic conditions
experienced in the last several years in many of the Company's domestic and
international industrial markets continued to exist in 2001. However, the
activity level in these markets has shown improvement, as evidenced by the Power
Transmission backlog of $31.5 million as of December 31, 2001, compared to $20.8
million as of December 31, 2000.

        Power Transmission gross profit and gross margin, however, increased to
$18.9 million and 30.3%, respectively, for the year ended December 31, 2001,
from $15.6 million and 24.8%, respectively, for the year ended December 31,
2000. This improvement was due to a combination of higher margins on new
equipment sales and increased absorption of fixed overhead costs resulting from
volume increases attributable to gearboxes supplied to the Company's Oil Field
segment.

        Direct selling, general and administrative expenses for Power
Transmission decreased to $10.1 million, or 5.7%, for the year ended December
31, 2001, from $10.7 million for the year ended December 31, 2000. This decrease
was due to lower personnel-related expenses, reduced severance payments and
lower depreciation expense, partially offset by higher bad debt expense.

        Trailer sales for the year ended December 31, 2001, decreased 53.6% to
$34.1 million from $73.6 million for the year ended December 31, 2000, due to
the continued industry-wide decline in the market for new trailers that began in
1999. Due to a combination of lower shipping volumes, higher fuel costs, higher
personnel costs and higher insurance rates, freight companies have either
significantly reduced orders for new trailers or have gone out of business.
Trailer manufacturers have seen revenue declines of as much as 75%, with several
shutting down completely. Some improvement has been seen in the trailer market,
as demonstrated in the increased backlog to $13.5 million as of December 31,
2001, compared to $9.5 million as of December 31, 2000. This backlog level,
though, was still well below traditional levels.

        Trailer gross profit and margin declined to $0.2 million and 0.7%,
respectively, for the year ended December 31, 2001, from $4.9 and 6.7%,
respectively, for the year ended December 31, 2000, due to fixed manufacturing
overhead not declining at the same rate as revenue.

        Direct selling, general and administrative expenses for Trailer
decreased to $2.2 million, or 16.9%, for the year ended December 31, 2001, from
$2.6 million for the year ended December 31, 2000. This decrease was due to a
combination of lower personnel-related expenses and insurance claims.

        Corporate administrative expenses, which are allocated to the segments
primarily based on third-party revenues, increased to $13.3 million, or 13.6%,
for the year ended December 31, 2001, from $11.7 million for the year ended
December 31, 2000, due to increased legal expenses and non-recurring expenses
related to the Company's 100th anniversary.

        Interest expense for the year ended December 31, 2001, totaled $0.9
million compared to $1.4 million for the year ended December 31, 2000, due to
lower average short and long-term debt balances in 2001 compared to 2000. Since
the majority of outstanding debt will be repaid in July 2002, interest expense
will be greatly reduced after that date. Other income (expense) of $(0.3)
million for 2001 was reduced from $0.1 million for 2000.

        Pension income, which is reported as a reduction of cost of sales in
each segment, decreased to $5.9 million, or 6.9%, for the year ended December
31, 2001, from $6.4 million for the year ended December 31, 2000. While the
actual market return of the plan assets has been down, pension income is based
on expected long-term return projections and not on current year activity.

LIQUIDITY AND CAPITAL RESOURCES

        The Company has historically relied on cash flows from operations and
third-party borrowings to finance its operations, including acquisitions,
dividend payments and stock repurchases.

        The Company's cash balance totaled $27.6 million at December 31, 2002,
compared to $18.1 million at December 31, 2001. For the year ended December 31,
2002, net cash provided by operating activities was $22.3 million, cash used in
investing activities totaled $4.3 million, cash used in financing activities
amounted to $8.8 million and the effect of foreign currency translation amounted
to $0.2 million. Significant components of cash provided by operating activities
include net earnings adjusted for non-cash expenses of $16.4 million and a net
decrease in working capital of $5.9 million. This decrease was primarily due to
lower trade receivables and inventory in the Oil Field segment. Cash used in
investing activities included net capital expenditures totaling $10.1 million,
partially offset by the sale of securities worth $5.9 million previously
escrowed for the purposes of paying long-term debt. Capital expenditures in 2002
were primarily for additions and replacements of production equipment and
operating vehicles in the Oil Field segment, the expansion into the Southeast
U.S. for repairing power transmission equipment and the addition of high-speed
testing equipment into the French Power Transmission facility. Capital
expenditures for 2003 are projected to be at or greater than the 2002 level.
Significant components of cash used in financing activities included payments on
long-term debt of $6.7 million, proceeds from stock option exercises of $2.6
million and dividend payments of $4.7 million or $0.72 per share.

        Total debt balances at December 31, 2002, including current maturities
of long-term debt, consisted of $0.4 million of notes payable to various banks.
As of December 31, 2002, the Company had no outstanding debt associated with the
Bank Facility discussed below. Total debt decreased by $6.5 million during 2002
due to principal payments on long-term notes payable totaling $6.7 million with
an offset of $0.2 million in the Company's foreign currency denominated debt as
a result of changes in exchange rates.

        During the fourth quarter of 2002, the Company completed and signed a
three-year $27.5 million credit facility with a domestic bank (the "Bank
Facility") consisting of an unsecured revolving line of credit that provides for
up to $17.5 million of committed borrowings along with an additional $10.0
million discretionary line of credit. Borrowings under the Bank Facility bear
interest, at the Company's option, at either the greater of (i) the prime rate,
(ii) the base CD rate plus an applicable margin or (iii) the Federal Funds
Effective Rate plus an applicable margin or the London Interbank Offered Rate
("LIBOR") plus an applicable margin, depending on certain ratios as defined in
the agreement. As of December 31, 2002, no amounts were outstanding of the $27.5
million of the revolving line of credit under the terms of the Bank Facility.

        The Company currently has a stock repurchase plan under which the
Company is authorized to spend up to $17.1 million for repurchases of its common
stock. Pursuant to this plan, the Company has repurchased a total of 826,870
shares of its common stock at an aggregate purchase price of $16.9 million. No
shares were repurchased during the year ended December 31, 2002. Repurchased
shares are added to treasury stock and are available for general corporate
purposes including the funding of the Company's stock option plans. As of
December 31, 2002, the Company held 364,462 shares of treasury stock at an
aggregate cost of approximately $7.5 million. Authorizations of approximately
$0.2 million remained at December 31, 2002.

        The Company had no significant lease or contractual obligations as of
December 31, 2002, that would negatively impact cash requirements in subsequent
periods.

        The Company believes that its cash flows from operations and its
available borrowing capacity under its credit agreements will be sufficient to
fund its operations, including planned capital expenditures, dividend payments
and stock repurchases, through December 31, 2003.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

        In June 2001, the Financial Accounting Standards Board issued Statement
No. 143, "Accounting for Asset Retirement Obligations." This standard requires
asset retirement costs to be capitalized as part of the cost of the related
tangible long-lived asset and subsequently allocated to expense using a
systematic and rational method over the useful life of the asset. The statement
is effective for fiscal years beginning after June 15, 2002. The transition
adjustment resulting from the adoption of this statement will be reported as a
cumulative effect of a change in accounting principle. The Company adopted
Statement No. 143 as of January 1, 2003, and it did not have an impact on the
Company's consolidated financial position or results of operations.

        In April 2002, the Financial Accounting Standards Board issued Statement
No. 145, "Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB of
FASB Statement No. 13, and Technical Corrections." This standard rescinds SFAS
No. 4, "Reporting Gains and Losses from Extinguishment of Debt," an amendment of
APB Opinion No. 30, and SFAS No. 64, "Extinguishments of Debt Made to Satisfy
Sinking-Fund Requirements," which amended SFAS 4, as these two standards
required that all gains and losses from the extinguishment of debt be aggregated
and, if material, classified as an extraordinary item. Consequently, such gains
and losses will now be classified as extraordinary only if they meet the
criteria for extraordinary treatment set forth in APB Opinion 30, "Reporting the
Results of Operations - Reporting the Effects of Disposal of a Segment of a
Business, and Extraordinary, Unusual and Infrequently Occurring Events and
Transactions." The statement also rescinds SFAS No. 44, "Accounting for
Intangible Assets of Motor Carriers," an amendment of Chapter 5 of ARB No. 43
and an interpretation of APB Opinions 17 and 30, because the discrete event to
which that statement relates is no longer relevant. In addition, SFAS 145 amends
SFAS No. 13, "Accounting for Leases," to require that certain lease
modifications that have economic effects similar to sale-leaseback transactions
be accounted for in the same manner as such transactions. Furthermore, the
statement makes certain technical corrections, which the FASB deemed to be
non-substantive, to a number of existing accounting pronouncements. The
provisions of SFAS 145 related to the rescission of SFAS 4 and 64 are effective
for fiscal years beginning after May 15, 2002. The provisions related to the
amendment of SFAS 13 are effective for transactions occurring after May 15,
2002. All other provisions of SFAS 145 are effective for financial statements
issued on or after May 15, 2002. The Company adopted Statement No. 145 as of
January 1, 2003, and it did not have an impact on the Company's consolidated
financial position or results of operations.

        In June 2002, the Financial Accounting Standards Board issued Statement
No. 146, "Accounting for Costs Associated with Exit or Disposal Activities."
This statement requires companies to recognize costs associated with
restructurings, discontinued operations, plant closings or other exit or
disposal activities when incurred rather than at the date a plan is committed
to. The statement is effective for exit or disposal activities initiated after
December 31, 2002. The Company adopted Statement No. 145 as of January 1, 2003,
and it did not have an impact on the Company's consolidated financial position
or results of operations.

        In October 2002, the Financial Accounting Standards Board issued
Statement No. 147, "Acquisitions of Certain Financial Institutions," which
applies to all acquisitions of financial institutions except those between two
or more mutual enterprises, which is being addressed in a separate project.
Statement 147 supersedes the specialized accounting guidance in paragraph 5 of
SFAS No. 72, "Accounting for Certain Acquisitions of Banking or Thrift
Institutions," and amends FASB Interpretation No. 9, "Applying APB Opinions No.
16 and 17 When a Savings and Loan Association or a Similar Institution Is
Acquired in a Business Combination Accounted for by the Purchase Method";
therefore, if certain criteria in Statement 147 are met, the amount of the
unidentifiable intangible asset will be reclassified to goodwill upon adoption
of this statement. Restatement of previously issued financial statements will be
required. Those transition provisions are effective as of October 1, 2002;
however, early application is permitted. Statement 147 also amends the scope of
Statement No. 144, "Accounting for the Impairment or Disposal of Long-Lived
Assets," to include long-term customer-relationship intangible assets such as
depositor- and borrower-relationship intangible assets and credit cardholder
intangible assets. The Company adopted Statement No. 145 as of January 1,2003,
and it did not have an impact on the Company's consolidated financial position
or results of operations.

        In December 2002, the Financial Accounting Standards Board issued
Statement No. 148, "Accounting for Stock-Based Compensation- Transition and
Disclosure." This statement amends FASB Statement No. 123, "Accounting for
Stock-Based Compensation," to provide alternate methods of transition to SFAS
No. 123's fair value method of accounting for stock-based employee compensation.
Statement No. 148 also amends the disclosure provisions of SFAS No. 123 and APB
Opinion No. 28, "Interim Financial Reporting," to require disclosure in the
summary of significant accounting policies of the effects of an entity's
accounting policy with respect to stock-based employee compensation on reported
net income and earnings per share in annual and interim financial statements.
While SFAS No. 148 does not amend SFAS No. 123 to require companies to account
for employee stock options using the fair value methods, the disclosure
provisions of SFAS No. 148 are applicable to all companies with stock-based
employee compensation, regardless of whether they account for that compensation
using the fair value method of SFAS No. 123 or the intrinsic value method of APB
Opinion No. 25. As allowed by SFAS No. 123, the Company has elected to continue
to utilize the accounting method prescribed by APB Opinion No. 25 and has
adopted the disclosure requirements of SFAS No. 148 as of December 31, 2002.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

        The discussion and analysis of financial condition and results of
operations are based upon the Company's consolidated financial statements, which
have been prepared in accordance with accounting principles generally accepted
in the United States of America. The preparation of these financial statements
requires the Company to make estimates and judgments that affect the reported
amounts of assets, liabilities, revenues and expenses and related disclosure of
contingent assets and liabilities. The Company evaluates its estimates on an
ongoing basis, based on historical experience and on various other assumptions
that are believed to be reasonable under the circumstances. Actual results may
differ from these estimates under different assumptions or conditions. The
Company believes the following critical accounting policies affect its more
significant judgments and estimates used in preparation of its consolidated
statements.

        The Company extends credit to customers in the normal course of
business. Management performs ongoing credit evaluations of our customers and
adjusts credit limits based upon payment history and the customer's current
credit worthiness. An allowance for doubtful accounts has been established to
provide for estimated losses on receivable collections. The balance of this
allowance is determined by regular reviews of outstanding receivables and
historical experience. As the financial condition of customers change,
circumstances develop or additional information becomes available, adjustments
to the allowance for doubtful accounts may be required.

        Revenue is not recognized until it is realized or realizable and earned.
The criteria to meet this guideline are: persuasive evidence of an arrangement
exists, delivery has occurred or services have been rendered, the price to the
buyer is fixed or determinable and collectibility is reasonably assured. The
Company also recognizes Bill-and-Hold transactions when the product is completed
and is ready to be shipped and the risk of loss on the product has been
transferred to the customer.

        The Company has made significant investments in inventory to service its
customers. On a routine basis, the Company uses estimates in determining the
level of reserves required to state inventory at the lower of cost or market.
Management's estimates are primarily influenced by market activity levels,
production requirements, the physical condition of products and technological
innovation. Changes in any of these factors may result in adjustments to the
carrying value of inventory. Also, the Company accounts for a significant
portion of its inventory under the LIFO method. The LIFO reserve can be impacted
by changes in the LIFO layers and by inflation index adjustments.

        Long-lived assets, including goodwill, held and used by the Company are
reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be reasonable. The Company assesses
the recoverability of long-lived assets by determining whether the carrying
value can be recovered through projected discounted cash flows, based on
expected future operating results. Future adverse market conditions or poor
operating results could result in the inability to recover the current carrying
value and thereby possibly requiring an impairment charge in the future.

                                        9

<PAGE>

        Deferred tax assets and liabilities are recognized for the differences
between the book basis and tax basis of the net assets of the Company. In
providing for deferred taxes, management considers current tax regulations,
estimates of future taxable income and available tax planning strategies.
Changes in state, federal and foreign tax laws as well as changes in the
financial position of the Company could also affect the carrying value of
deferred tax assets and liabilities. If management estimates that some or all of
any deferred tax assets will expire before realization or that the future
deductibility is not probable, a valuation allowance would be recorded.

        The Company is subject to claims and legal actions in the ordinary
course of business. The Company maintains insurance coverage for various aspects
of its businesses and operations. The Company retains a portion of the insured
losses that occur through the use of deductibles. Management regularly reviews
estimates of reported and unreported insured and non-insured claims and legal
actions and provides for losses through reserves. As circumstances develop and
additional information becomes available, adjustments to loss reserves may be
required.

        The Company sells certain of its products to customers with a product
warranty that provides repairs at no cost to the customer or the issuance of
credit to the customer. The length of the warranty term depends on the product
being sold, but ranges from one year to five years. The Company accrues its
estimated exposure to warranty claims based upon historical warranty claim costs
as a percentage of sales multiplied by prior sales still under warranty at the
end of any period. Management reviews these estimates on a regular basis and
adjusts the warranty provisions as actual experience differs from historical
estimates or other information becomes available.

        The Company offers a defined benefit plan and other benefits upon the
retirement of its employees. Assets and liabilities associated with these
benefits are calculated by third-party actuaries under the rules provided by
various accounting standards, with certain estimates provided by management.
These estimates include the discount rate, expected rate of return of assets and
the rate of increase of compensation and health claims. On a regular basis,
management reviews these estimates by comparing them to actual experience and
those used by other companies. If a change in an estimate is made, the carrying
value of these assets and liabilities may have to be adjusted.

FORWARD-LOOKING STATEMENTS AND ASSUMPTIONS

        This Annual Report on Form 10-K contains forward-looking statements and
information, within the meaning of the Private Securities Litigation Reform Act
of 1995, that are based on management's beliefs as well as assumptions made by
and information currently available to management. When used in this report, the
words "anticipate," "believe," "estimate," "expect" and similar expressions are
intended to identify forward-looking statements. Such statements reflect the
Company's current views with respect to certain events and are subject to
certain assumptions, risks and uncertainties, many of which are outside the
control of the Company. These risks and uncertainties include, but are not
limited to, (i) oil prices, (ii) capital spending levels of oil producers, (iii)
availability and prices for raw materials and (iv) general industry and economic
conditions. Should one or more of these risks or uncertainties materialize, or
should underlying assumptions prove incorrect, actual results may vary
materially from those anticipated, believed, estimated or expected. The Company
undertakes no obligations to update or revise its forward-looking statements,
whether as a result of new information, future events or otherwise.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        The Company does not utilize financial instruments for trading purposes.
The Company's financial instruments include cash, accounts receivable, accounts
payable, invested funds and debt obligations. The book value of accounts
receivable, short-term debt and accounts payable are considered to be
representative of their fair market value because of the short maturity of these
instruments. The Company believes the carrying values of its long-term debt
obligations approximate fair values because the interest rates on these
obligations are comparable to what the Company believes it could currently
obtain for debt with similar terms and maturities. The Company's accounts
receivable are not concentrated in one customer or industry and are not viewed
as an unusual credit risk.

                    REPORTS OF INDEPENDENT PUBLIC ACCOUNTANTS

        We have audited the accompanying balance sheet of Lufkin Industries,
Inc. (the "Company) as of December 31, 2002 and the related statements of
income, stockholders' equity and cash flows for the year then ended. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit. The financial statements of Lufkin Industries, Inc. as of December
31, 2001, and for the two years then ended, were audited by other auditors who
have ceased operations. Those auditors expressed an unqualified opinion on those
financial statements in their report dated February 8, 2002.

        We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

        In our opinion, such financial statements present fairly, in all
material respects, the financial position of the Company as of December 31,
2002, and the results of its operations and its cash flows for the years then
ended in conformity with accounting principles generally accepted in the United
States of America.

        As discussed in Note 1 to the financial statements, effective January 1,
2002, the Company changed its method of accounting for goodwill and other
intangible assets upon adoption of Statement of Financial Accounting Standards
("SFAS") No. 142, "Goodwill and Other Intangible Assets."

        As discussed above, the consolidated financial statements of the Company
as of December 31, 2001, and for each of the two years in the period ended
December 31, 2001, were audited by other auditors who have ceased operations. As
described in Notes 1 and 7, these financial statements have been revised to
include the transitional disclosures required by SFAS No. 142, which was adopted
by the Company as of January 1, 2002, and have also been adjusted to provide for
a reclassification between current and non- current other assets. Our audit
procedures with respect to the disclosures in Notes 1 and 7, with respect to
2001 and 2000 included (a) agreeing the previously reported net income to the
previously issued financial statements and the adjustments to reported net
income representing amortization expense (including related tax effects)
recognized in those periods related to goodwill to the Company's underlying
records obtained from management, (b) reviewing the underlying records obtained
from management associated with the reclassification, (c) testing the
mathematical accuracy of either the reclassification or the reconciliation of
adjusted net income to reported net income, and the related earnings-per-share
amounts, and (d) recalculating the change in working capital as presented in the
Statement of Cash Flows for the period ended December 31, 2000. In our opinion,
the transitional disclosures and the noted reclassification for 2001 and 2000 in
Note 1 and 7 are appropriate. However we were not engaged to audit, review, or
apply any procedures to the 2001 and 2000 consolidated financial statements of
the Company other than with respect to such disclosures and, accordingly, we do
not express an opinion or any other form of assurance on the 2001 and 2000
consolidated financial statements taken as a whole.

Below is a copy of the report previously issued by Arthur Andersen LLP, the
Company's former independent public accountants, in connection with the
Company's Annual Report for the year ended December 31, 2001. Arthur Andersen is
unable to issue an updated report. Certain financial statements covered by this
opinion have not been included in the accompanying financial statements.

To the Shareholders of Lufkin Industries, Inc.:

        We have audited the accompanying consolidated balance sheets of Lufkin
Industries, Inc. (a Texas corporation) and subsidiaries (collectively, the
Company) as of December 31, 2001 and 2000, and the related consolidated
statements of earnings, shareholders' equity and cash flows for each of the
three years in the period ended December 31, 2001. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

        We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the consolidated
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

        In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Lufkin Industries, Inc., and subsidiaries as of December 31, 2001 and 2000, and
the consolidated results of their operations and their cash flows for each of
the three years in the period ended December 31, 2001, in conformity with
accounting principles generally accepted in the United States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) CORPORATE ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        Lufkin Industries, Inc. and its consolidated subsidiaries (collectively,
the "Company") manufacture and sell oil field pumping units, power transmission
products and highway trailers throughout the world.

        Principles of consolidation: The consolidated financial statements
include the accounts of Lufkin Industries, Inc. and its consolidated
subsidiaries after elimination of all significant inter-company accounts and
transactions.

        Use of estimates: The preparation of financial statements in conformity
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities as of the date of the financial statements and the reported amounts
of revenues and expenses during the reporting periods. Actual results could
differ from those estimates.

        Foreign currencies: Assets and liabilities of foreign operations are
translated into U.S. dollars at the exchange rate in effect at the end of each
accounting period, with any resulting gain or loss shown in accumulated other
comprehensive income in the shareholders' equity section of the balance sheet.
Income statement accounts are translated at the average exchange rates
prevailing during the period. Any gains or losses on transactions denominated in
another foreign currency are generally included in income as incurred.

        Cash equivalents: The Company considers all highly liquid investments
with maturities of three months or less when purchased to be cash equivalents.

        Invested funds: The Company's invested funds, which consisted of
government securities, were classified as held-to-maturity securities and were
carried at cost. Substantially all of the Company's invested funds at December
31, 2001, were restricted for payment of certain of the Company's notes payable.

        Inventories: The Company reports its inventories by using the last-in,
first-out (LIFO) and the first-in, first-out (FIFO) methods less reserves
necessary to report inventories at the lower of cost or estimated market.
Inventory costs include material, labor and factory overhead. On a routine
basis, the Company uses estimates in determining the level of reserves required
to state inventory at the lower of cost or market. Management's estimates are
primarily influenced by market activity levels, production requirements, the
physical condition of products and technological innovation. Changes in any of
these factors may result in adjustments to the carrying value of inventory. In
July, 1998, the Company began capitalizing certain maintenance and supplies
inventories to better match the estimated cost of such inventories with the
related equipment produced. Such inventories were capitalized and were amortized
over the three years of their estimated use and had the effect of increasing net
earnings by $0.3 million ($0.05 per diluted share) and $0.7 million ($0.12 per
diluted share) in 2001 and 2000, respectively.

        Property, plant and equipment (P. P. & E.): The Company records
investments in these assets at cost. Improvements are capitalized, while repair
and maintenance costs are charged to operations as incurred. Gains or losses
realized on the sale or retirement of these assets are reflected in income. The
Company periodically reviews its P. P. & E. for possible impairment whenever
events or changes in circumstance might indicate that the carrying amount of an
asset may not be recoverable. Depreciation for financial reporting purposes is
provided on a straight-line method based upon the estimated useful lives of the
assets. Accelerated depreciation methods are used for tax purposes. The
following is a summary of the Company's P. P. & E. useful lives:

                                            Useful Life (In Years)
--------------------------------------------------------------------
Land                                                          -
Land improvements                                   10.0 - 25.0
Buildings                                           12.5 - 40.0
Machinery and equipment                              3.0 - 12.5
Furniture and fixtures                               5.0 - 12.5
Computer equipment and software                      3.0 -  7.0

        Goodwill and other intangible assets: In June 2001, the Financial
Accounting Standards Board issued Statement of Financial Accounting Standards
("SFAS") No. 142, "Goodwill and Other Intangible Assets." SFAS No. 142
eliminated the amortization of goodwill and intangible asserts with indefinite
lives and requires that such assets be tested for impairment at least annually.
During the first quarter of 2002, the Company completed the impairment testing
by testing the fair value of each reporting unit to its carrying amount. Since
the fair value of each reporting unit exceeded the carrying value, no impairment
was recorded.

        The Company amortizes intangible assets with finite lives over the years
expected to be benefited.

        Income taxes: Deferred income tax assets or liabilities are recorded
based on the difference between the financial statement and income tax bases of
assets and liabilities using enacted tax rates. See Footnote 2 for more detail.

        Financial instruments: The Company's financial instruments include cash,
accounts receivable, accounts payable and debt obligations. The book value of
accounts receivable, short-term debt and accounts payable are considered to be
representative of their fair value because of the short maturity of these
instruments. The Company believes the carrying value of its long-term debt
approximates fair value because the interest rates of this debt are comparable
to what the Company believes it could currently obtain for debt with similar
terms and maturities.

        The Company adopted Statement of Financial Accounting Standards ("SFAS")
No. 133, "Accounting for Derivative Instruments and Hedging Activities," and
SFAS No. 138, "Accounting for Certain Derivative Instruments and Certain Hedging
Activities," an amendment of SFAS No. 133, as of the quarter ended March 31,
2001. These statements establish accounting and reporting standards that require
every derivative instrument, including certain derivative instruments embedded
in other contracts, to be recorded on the balance sheet as either an asset or a
liability measured at its fair value.

        As of December 31, 2002, the Company had no reportable derivatives. A
note payable, described in Footnote 4, had been designated as a hedge against
the Company's investment in its French operations, but had been fully paid as of
December 31, 2002. The changes in the fair value of this instrument were
recorded in accumulated other comprehensive income.

        Revenue recognition: Revenue is not recognized until it is realized or
realizable and earned. The criteria to meet this guideline are: persuasive
evidence of an arrangement exists, delivery has occurred or services have been
rendered, the price to the buyer is fixed or determinable and collectibility is
reasonably assured. The Company also recognizes Bill-and-Hold transactions when
the product is completed and is ready to be shipped and the risk of loss on the
product has been transferred to the customer.

        Amounts billed for shipping are classified as sales and costs incurred
for shipping are classified as cost of sales in the consolidated income
statement.

        Stock-based compensation: The Company has elected to follow the
accounting provisions of APB No. 25, "Accounting for Stock Issued to Employees,"
for stock-based compensation and to furnish the pro-forma disclosures required
under SFAS No. 148, "Accounting for Stock-Based Compensation- Transition and
Disclosures." APB No. 25 requires no recognition of compensation expense for
most stock-based compensation arrangements.

        Recently issued accounting pronouncements: In June 2001, the Financial
Accounting Standards Board issued Statement No. 143, "Accounting for Asset
Retirement Obligations." This standard requires asset retirement costs to be
capitalized as part of the cost of the related tangible long-lived asset and
subsequently allocated to expense using a systematic and rational method over
the useful life of the asset. The statement is effective for fiscal years
beginning after June 15, 2002. The transition adjustment resulting from the
adoption of this statement will be reported as a cumulative effect of a change
in accounting principle. The Company adopted Statement No. 143 as of January 1,
2003, and it did not have an impact on the Company's consolidated financial
position or results of operations.

        In April 2002, the Financial Accounting Standards Board issued Statement
No. 145, "Rescission of FASB Statements No. 4, 44, and 64, Amendment of FASB of
FASB Statement No. 13, and Technical Corrections." This standard rescinds SFAS
No. 4, "Reporting Gains and Losses from Extinguishment of Debt," an amendment of
APB Opinion No. 30, and SFAS No. 64, "Extinguishments of Debt Made to Satisfy
Sinking-Fund Requirements," which amended SFAS 4, as these two standards
required that all gains and losses from the extinguishment of debt be aggregated
and, if material, classified as an extraordinary item. Consequently, such gains
and losses will now be classified as extraordinary only if they meet the
criteria for extraordinary treatment set forth in APB Opinion 30, "Reporting the
Results of Operations - Reporting the Effects of Disposal of a Segment of a
Business, and Extraordinary, Unusual and Infrequently Occurring Events and
Transactions." The statement also rescinds SFAS No. 44, "Accounting for
Intangible Assets of Motor Carriers," an amendment of Chapter 5 of ARB No. 43
and an interpretation of APB Opinions 17 and 30, because the discrete event to
which that statement relates is no longer relevant. In addition, SFAS 145 amends
SFAS No. 13, "Accounting for Leases," to require that certain lease
modifications that have economic effects similar to sale-leaseback transactions
be accounted for in the same manner as such transactions. Furthermore, the
statement makes certain technical corrections, which the FASB deemed to be
non-substantive, to a number of existing accounting pronouncements. The
provisions of SFAS 145 related to the rescission of SFAS 4 and 64 are effective
for fiscal years beginning after May 15, 2002. The provisions related to the
amendment of SFAS 13 are effective for transactions occurring after May 15,
2002. All other provisions of SFAS 145 are effective for financial statements
issued on or after May 15, 2002. The Company adopted Statement No. 145 as of
January 1, 2003, and it did not have an impact on the Company's consolidated
financial position or results of operations.

        In June 2002, the Financial Accounting Standards Board issued Statement
No. 146, "Accounting for Costs Associated with Exit or Disposal Activities."
This statement requires companies to recognize costs associated with
restructurings, discontinued operations, plant closings or other exit or
disposal activities when incurred rather than at the date a plan is committed
to. The statement is effective for exit or disposal activities initiated after
December 31, 2002. The Company plans to adopt this statement as of the effective
date and will implement its provisions on a prospective basis.

        In October 2002, the Financial Accounting Standards Board issued
Statement No. 147, "Acquisitions of Certain Financial Institutions," which
applies to all acquisitions of financial institutions except those between two
or more mutual enterprises, which is being addressed in a separate project.
Statement 147 supersedes the specialized accounting guidance in paragraph 5 of
SFAS No. 72, "Accounting for Certain Acquisitions of Banking or Thrift
Institutions," and amends FASB Interpretation No. 9, "Applying APB Opinions No.
16 and 17 When a Savings and Loan Association or a Similar Institution Is
Acquired in a Business Combination Accounted for by the Purchase Method";
therefore, if certain criteria in Statement 147 are met, the amount of the
unidentifiable intangible asset will be reclassified to goodwill upon adoption
of this statement. Restatement of previously issued financial statements will be
required. Those transition provisions are effective as of October 1, 2002;
however, early application is permitted. Statement 147 also amends the scope of
Statement No. 144, "Accounting for the Impairment or Disposal of Long-Lived
Assets," to include long-term customer-relationship intangible assets such as
depositor- and borrower-relationship intangible assets and credit cardholder
intangible assets. The Company adopted Statement No. 145 and it did not have an
impact on the Company's consolidated financial position or results of
operations.

        In December 2002, the Financial Accounting Standards Board issued
Statement No. 148, "Accounting for Stock-Based Compensation- Transition and
Disclosure." This statement amends FASB Statement No. 123, "Accounting for
Stock-Based Compensation," to provide alternate methods of transition to SFAS
No. 123's fair value method of accounting for stock-based employee compensation.
Statement No. 148 also amends the disclosure provisions of SFAS No. 123 and APB
Opinion No. 28, "Interim Financial Reporting," to require disclosure in the
summary of significant accounting policies of the effects of an entity's
accounting policy with respect to stock-based employee compensation on reported
net income and earnings per share in annual and interim financial statements.
While SFAS No. 148 does not amend SFAS No. 123 to require companies to account
for employee stock options using the fair value methods, the disclosure
provisions of SFAS No. 148 are applicable to all companies with stock-based
employee compensation, regardless of whether they account for that compensation
using the fair value method of SFAS No. 123 or the intrinsic value method of APB
Opinion No. 25. As allowed by SFAS No. 123, the Company has elected to continue
to utilize the accounting method prescribed by APB Opinion No. 25 and has
adopted the disclosure requirements of SFAS No. 148 as of December 31, 2002.

        Product warranties: The Company sells certain of its products to
customers with a product warranty that provides repairs at no cost to the
customer or the issuance of credit to the customer. The length of the warranty
term depends on the product being sold, but ranges from one year to five years.
The Company accrues its estimated exposure to warranty claims based upon
historical warranty claim costs as a percentage of sales multiplied by prior
sales still under warranty at the end of any period. Management reviews these
estimates on a regular basis and adjusts the warranty provisions as actual
experience differs from historical estimates or other information becomes
available.

        Other: Certain prior year amounts have been reclassified to conform with
the current year presentation. Included in these reclassifications is a
reclassification to other current assets from other long-term assets totaling
$811,000. The respective reclassification was made to better reflect the
underlying nature and timing of the respective assets consistent with the
Company's current classification of such items. The reclassification had no
change on the Company's total assets of $246,069,000 as previously reported, and
effectively increased the Company's working capital by $811,000.

respectively.

        During 2002 and 2001, LIFO inventories were reduced in certain LIFO
pools and these reductions resulted in a liquidation of LIFO inventory
quantities carried at lower costs in prior years. The impact of the reductions
reduced net income in 2002 by approximately $34,000, net of taxes ($0.00 per
diluted share), and increased net income in 2001 by approximately $328,000, net
of taxes ($0.05 per diluted share.)

(7) GOODWILL & ACQUIRED INTANGIBLE ASSETS

Balances and related amortization expense for goodwill and acquired intangible
assets are as follows:

For the year ended 12/31/07                      -

The Company also has multi-year non-compete agreements with certain individuals
that are paid and expensed on an annual basis and thus are not recorded as
pre-paid assets. These agreements expire in 2003 and 2004. Expenses related to
these non-compete agreements were $64,000, $64,000 and $60,000 for the years
2002, 2001 and 2000, respectively. Estimated expenses for these agreements are
$51,000 and $4,000 in the years 2003 and 2004, respectively.

(8) DEBT OBLIGATIONS

        During the fourth quarter of 2002, the Company completed and signed a
three-year $27.5 million credit facility with a domestic bank (the "Bank
Facility") consisting of an unsecured revolving line of credit that provides for
up to $17.5 million of committed borrowings along with an additional $10.0
million discretionary line of credit. Borrowings under the Bank Facility bear
interest, at the Company's option, at either the greater of (i) the prime rate,
(ii) the base CD rate plus an applicable margin or (iii) the Federal Funds
Effective Rate plus an applicable margin or the London Interbank Offered Rate
("LIBOR") plus an applicable margin, depending on certain ratios as defined in
the agreement. As of December 31, 2002, no amounts were outstanding of the $27.5
million of the revolving line of credit under the terms of the Bank Facility.

The Company's long-term notes payable at December 31, 2002 and 2001 consisted of
the following:

        The Company had designated the note payable denominated in euros that
matured in December 2002 as a hedge against its investment in its French
operations.

        Under the terms of the notes payable to individuals, invested funds in
the amount of $5,106,000 at December 31, 2001, were restricted for the payment
of these notes.

(9) STOCK OPTION PLANS

        The Company has two stock option plans, the 2000 plan for employees and
the 1996 plan for non-employee directors, that provide for the granting of
options to outside directors and key employees to purchase an aggregate of not
more than 1,050,000 shares of the Company's common stock at fair market value on
the date of grant. Options become exercisable from the initial grant date to
four years after the grant date. The options expire ten years from the date of
grant. Outstanding options may be canceled and reissued under terms specified in
the plans. The 1990 plan, which originally was authorized to grant 1,100,000
options, will remain in effect until all awards granted under this plan have
been satisfied or expire. As of December 31, 2002, 535,333 options remained
outstanding and 494,833 options remained exercisable from the 1990 plan.

The following table summarizes activity under the Company's stock option plans:

        The Company accounts for its stock option plans under APB Opinion No. 25
under which no compensation cost has been recognized. Had compensation cost for
these plans been accounted for consistent with SFAS No. 123, "Accounting for

        The effects of applying SFAS No. 123 to the pro forma disclosure amounts
may not be indicative of future amounts. SFAS No. 123 does not apply to options
awarded prior to 1995, and additional awards in future years are anticipated.
The fair value of each option grant is estimated on the date of grant using the
Black-Scholes option-pricing model with the following assumptions:

2002 Grants          Expected dividend yield                  2.49% - 3.19%
                     Expected stock price volatility        38.31% - 38.59%
                     Risk free interest rate                  4.08% - 5.06%
                     Expected life of options                      10 years

2001 Grants          Expected dividend yield                  2.80% - 3.80%
                     Expected stock price volatility        35.74% - 37.91%

(10)  STOCK REPURCHASE PLAN

      The Company has a stock repurchase plan under which the Company has been
authorized to spend up to $17,100,000 for repurchases of its common stock. The
Company repurchased no shares in 2002 or 2001 but repurchased 110,314 shares at
an aggregate cost of $2,009,000 in 2000. Repurchased shares are added to
treasury stock and are available for general corporate purposes including the
funding of the Company's stock option plans. Authorizations of approximately
$152,000 remained at December 31, 2002.

(11) CAPITAL STOCK

      The Company has adopted a "Shareholder Rights Plan" (the "Plan")
designed to protect against unsolicited attempts to acquire control of the
Company that the Board believes are not in the best interest of the
shareholders. The Plan provides for the possible issuance of a dividend of one
common stock purchase right for each outstanding share of common stock. Under
certain conditions, each right may be exercised to purchase one share of common
stock at an exercise price of $75, subject to adjustment. Under certain
circumstances, the rights entitle holders to purchase the common stock of the
Company or an acquiring company having a value of twice the exercise price of
the rights. The rights would become exercisable, or transferable apart from the
common stock, ten days after a person or group acquired 20% or more, or
announced or made a tender offer for 30% or more, of the outstanding common
stock. Under certain circumstances, all rights owned by an acquiring person
would be null and void. The rights expire on May 31, 2006, and may be redeemed
by the Company at any time prior to the occurrence of certain events at $.05 per
right.

      The Company is also authorized to issue 2,000,000 shares of preferred
stock, the terms and conditions to be determined by the Board of Directors in
creating any particular series.

(12)  RETIREMENT BENEFITS

      The Company has noncontributory pension plans covering substantially all
employees. The benefits provided by these plans are measured by length of
service, compensation and other factors, and are currently funded by trusts
established under the plans. Funding of retirement costs for these plans
complies with the minimum funding requirements specified by the Employee
Retirement Income Security Act, as amended. Plan investment assets are invested
primarily in equity securities, United States government securities and cash
equivalents.

      The following tables illustrate the change in benefit obligation,
change in plan assets and funded status of the pension plans:

        The Company also has qualified defined contribution retirement plans
covering substantially all of its employees. The Company makes contributions of
75% of employee contributions up to a maximum employee contribution of 6% of
employee earnings. Employees may contribute up to an additional 6% (in 1%
increments) which is not subject to match by the Company. All obligations of the
Company are funded through December 31, 2002. The Company's expense for these
plans totaled $1,852,000, $1,948,000 and $1,715,000 in 2002, 2001 and 2000,
respectively.

        The Company sponsors two defined benefit postretirement plans that cover
both salaried and hourly employees. One plan provides medical benefits, and the
other plan provides life insurance benefits. Both plans are contributory, with
retiree contributions adjusted periodically. The Company accrues the estimated
costs of the plans over the employee's service periods.

        The Company's postretirement health care plan is unfunded. For
measurement purposes, the submitted claims medical trend was assumed to be 9.25%
in 1997. Thereafter, the Company's obligation is fixed at the amount of the
Company's contribution for 1997.

(13)  COMMITMENTS AND CONTINGENCIES

        Legal proceedings: A class action complaint was filed in the United
States District Court for the Eastern District of Texas on March 7, 1997, by an
employee and a former employee which alleged race discrimination in employment.
Certification hearings were conducted in Beaumont, Texas in February of 1998 and
in Lufkin, Texas in August of 1998. The District Court in April of 1999 issued a
decision that certified a class for this case, which includes all persons of a
certain minority employed by the Company from March 6, 1994, to the present. The
Company appealed this class certification decision by the District Court to the
5th Circuit United States Court of Appeals in New Orleans, Louisiana. This
appeal was denied on June 23, 1999. The Company is defending this action
vigorously. Furthermore, the Company believes that the facts and the law in this
action support its position and is confident that it will prevail if this case
is tried on its merits.

        In the case of Echometer and James N. McCoy vs. Lufkin Industries, Inc.,
the plaintiff filed suit in U.S. District Court alleging infringement of a Data
Processing and Display for Echo Sounding Patent. The Company has vigorously
defended its position that its fluid level product does not infringe the
plaintiff's patent. Trial for this case is scheduled for May 2003.

        There are various other claims and legal proceedings arising in the
ordinary course of business pending against or involving the Company wherein
monetary damages are sought. It is management's opinion that the Company's
liability, if any, under such claims or proceedings would not materially affect
its consolidated financial position or results of operations.

        Product warranties: The change in the aggregate product warranty
liability for the year ended December 31, 2002, is as follows:

($000's)

(14)  CONCENTRATIONS OF CREDIT RISK

      The Company's concentration with respect to trade accounts receivable is
limited. The large number of customers and diversified customer base across the
three segments significantly reduces the Company's credit risk. The Company also
has strict policies regarding the granting of credit to customers and does not
offer credit terms to those customers that do not meet certain financial
criteria and other guidelines.

(15)  BUSINESS SEGMENT INFORMATION

      The Company operates with three business segments--Oil Field, Power
Transmission and Trailer. As stated in the Management's Discussion and Analysis
section, the Foundry segment has been combined with the Oil Field segment to
reflect current business operations. Prior period data has been adjusted to
reflect this change. The three operating segments are supported by a common
corporate group. The accounting policies of the segments are the same as those
described in the summary of major accounting policies. Corporate expenses and
certain assets are allocated to the operating segments primarily based upon
third party revenues. The following is a summary of key business segment and
product group information:

          defined in Exchange Act Rules 13a-14 and 15d-14) for the registrant
          and we have:

               a.   designed such disclosure controls and procedures to ensure
                    that material information relating to the registrant,
                    including its consolidated subsidiaries, is made known to us
                    by others within those entities, particularly during the

                    Date"); and

               c.   presented in this annual report our conclusions about the
                    effectiveness of the disclosure controls and procedures
                    based on our evaluation as of the Evaluation Date;

     5.   The registrant's other certifying officers and I have disclosed, based
          on our most recent evaluation, to the registrant's auditors and the
          audit committee of registrant's board of directors (or persons
          performing the equivalent function):

               a.   all significant deficiencies in the design or operation of
                    internal controls which could adversely affect the
                    registrant's ability to record, process, summarize and
                    report financial data and have identified for the
                    registrant's auditors any material weaknesses in internal
                    controls; and

               b.   any fraud, whether or not material, that involves management
                    or other employees who have a significant role in the
                    registrant's internal controls; and

     6.   The registrant's other certifying officers and I have indicated in
          this annual report whether or not there were significant changes in
          internal controls or in other factors that could significantly affect

          evaluation, including any corrective actions with regard to
          significant deficiencies and material weaknesses.
