                 THE LAMSON & SESSIONS CO. AND SUBSIDIARIES

                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                (UNAUDITED)

NOTE A - BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements do not include all
of the information and notes required by generally accepted accounting
principles for complete financial statements. In the opinion of management, all
adjustments (consisting of normal recurring accruals and changes in accounting
estimates) considered necessary for a fair presentation have been included.

NOTE B - INCOME TAXES

The third quarter 2001 income tax provision was calculated based on management's
estimate of the effective tax rate for the year. The difference between this
rate and the applicable statutory tax rate is due to the tax treatment of
goodwill amortization generated with the 2000 acquisition of Pyramid Industries,
Inc. ("Pyramid"). The provision for 2000 is primarily a non-cash charge.

NOTE C - BUSINESS SEGMENTS

The Company's reportable segments are as follows:

CARLON - INDUSTRIAL, RESIDENTIAL, COMMERCIAL, TELECOMMUNICATIONS AND UTILITY
CONSTRUCTION: The major customers served are electrical contractors and
distributors, original equipment manufacturers, electric power utilities, cable
television (CATV), telephone and telecommunications companies. The principal
products sold by this segment include electrical, telecommunications and wire
raceway systems and a broad line of nonmetallic enclosures, outlet boxes and
electrical fittings. Examples of the applications for the products included in
this segment are multi-cell duct systems or High Density Polyethylene (HDPE)
conduit designed to protect underground fiber optic cables, allowing future
cabling expansion and flexible conduit used inside buildings to protect
communications cable. The two 2000 acquisitions of Pyramid and Ameriduct
Worldwide, Inc. ("Ameriduct") are included as part of the Carlon segment.

LAMSON HOME PRODUCTS - CONSUMER: The major customers served are home centers and
mass merchandisers for the "do-it-yourself" home repair market. The products
included in this segment are outlet boxes, liquidtight conduit, electrical
fittings, chimes and lighting controls.

PVC PIPE: This business segment supplies electrical, power and communications
conduit to the electrical distribution, telecommunications, consumer and power
utility markets. The 1/2-inch to 6-inch electrical and telecommunications
conduit is made from polyvinylchloride (PVC) and is used to protect wire or
fiber optic cables supporting the infrastructure of our power or
telecommunications systems. In addition, this segment provides closed-profile,
engineered sewer pipe ranging in diameter from 21 inches to 54 inches to various
municipalities and private contractors for drainage systems in new construction
and rehabilitation markets.

THE LAMSON & SESSIONS CO. AND SUBSIDIARIES

NOTE F - DERIVATIVES AND HEDGING

Effective as of December 31, 2000, the Company adopted Statement of Financial
Accounting Standards No. (SFAS) 133, "Accounting for Derivative Instruments and
Hedging Activities" which was issued in June, 1998 by the Financial Accounting
Standards Board (FASB), as amended by SFAS 137, "Accounting for Derivative
Instruments and Hedging Activities - Deferral of Effective Date of SFAS 133" and
SFAS 138, "Accounting for Certain Derivative Instruments and Certain Hedging
Activities."

As a result of the adoption of SFAS 133, the Company is required to recognize
all derivative financial instruments as either assets or liabilities at fair
value. Derivative instruments that are not hedges must be adjusted to fair value
through net income. Under the provisions of SFAS 133, changes in the fair value
of derivative instruments that are classified as fair value hedges are offset
against changes in the fair value of the hedged assets, liabilities, or firm
commitments, through net income. Changes in the fair value of derivative
instruments that are classified as cash flow hedges are recognized in other
comprehensive income until such time as the hedged items are recognized in net
income.

The adoption of SFAS 133 did not result in any transition adjustment as the
Company had no derivative instruments outstanding at December 31, 2000. During
the first quarter of 2001, the Company entered into two interest rate swap
agreements for a total notional amount of $58.5 million which effectively fixes
interest rates on its variable rate debt at 5.41% and 5.48% plus the Company's
risk premium of 1.5% to 3.5%, respectively. These transactions are considered
cash flow hedges and, thus, the fair market value at the end of the third
quarter of $1,357,000 (net of tax) loss, has been recognized in other
comprehensive income (loss). There is no ineffectiveness on the cash flow
hedges, therefore, all changes in the fair value of these derivatives are
recorded in equity and not included in the current period's income statement.
Approximately $911,000 (net of tax) loss of the fair value of the hedges is
classified as current, with the remaining $446,000 (net of tax) loss
classification as long-term.

The Company has no derivative instruments that are classified as fair value
hedges.

NOTE G - RECENT ACCOUNTING PRONOUNCEMENTS

In June 2001, the Financial Accounting Standards Board issued Statements of
Financial Accounting Standards No. 141, Business Combinations, and No. 142,
Goodwill and Other Intangible Assets, effective for fiscal years beginning after
December 15, 2001. Under the new rules, goodwill will no longer be amortized but
will be subject to annual impairment tests in accordance with the Statements.
Other intangible assets will continue to be amortized over their useful lives.

The Company will apply the new rules on accounting for goodwill in the first
quarter of 2002. During 2002, the Company will perform the first of the required
impairment tests of goodwill as of December 30, 2001 and has not yet determined
what the effect of these tests will be on the earnings and financial position of
the Company.

ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
--------------------------------------------------------------------------------
OF OPERATIONS
-------------

RESULTS OF OPERATIONS

Net sales were $90.6 million in the third quarter of 2001, a 2.6% increase over
the third quarter of 2000. The Carlon segment increased net sales by 39.4% in
the current quarter compared to the prior year period. The majority of this net
sales increase is due to acquisitions which contributed $17.1 million in net
sales in the third quarter 2001 compared to $1.3 million in the same period of
2000. Lamson Home Products experienced a sales decline during the third quarter
of 2001 of 6.5% off a strong third quarter in 2000. Retailers in the home
improvement sector resumed their reduction in inventory levels and experienced
softness in sales as the economy slowed and consumer confidence fell. The PVC
Pipe Business experienced a 29% decline in net sales this quarter compared to
the third quarter of 2000. As in the second quarter of 2001, the volume of
electrical and telecommunications conduit shipped continues to be strong, up
8.3% over the third quarter of 2000. However, pricing remains depressed as
average selling prices dropped 7.2% from the second quarter of 2001 and is 35%
lower than the third quarter of 2000.

For the first three quarters of 2001, net sales increased by 6.2% from the first
three quarters of 2000. The Carlon business segment net sales increased $47.4
million while both the Lamson Home Products and PVC Pipe segments net sales
declined 5.0% and 25.8%, respectively, during the first three quarters of 2001
compared to the same period of 2000. Acquisitions from fiscal 2000 contributed
approximately $56.0 million in net sales for the first three quarters of 2001 in
the Carlon segment. Net sales are off for the remainder of the business segment
by almost 8.6% during the first three quarters of 2001 due to the general
slowdown in the economy and decline in telecom infrastructure project activity.
Lamson Home Products has experienced very inconsistent demand patterns from its
largest customer so far in 2001 as it deals with internal restructuring and
policy changes. PVC Pipe volume is up 13.8% from the first three quarters of
2000 while pricing is down by approximately 33.0%, which illustrates a continued
oversupply of PVC resin availability compared to current market demand.

Gross margin was 15.0% in the third quarter 2001 representing a 42.0% decline
from the 25.9% gross margin achieved in the third quarter of 2000. This
quarter's results lowered the gross margin year-to-date in 2001 to 17.3%
compared to 27.4% for the first three quarters of 2000. The majority of this
decline in the third quarter and year-to-date has occurred in the PVC Pipe
Business as selling prices have declined significantly as described above while
average PVC resin cost was lower by 17.7% in the third quarter of 2001 and 13.5%
for the first nine months of 2001, compared to the respective periods in 2000.
In addition, there has been a shift in product mix away from the more profitable
telecommunication duct to electrical conduit as the large Regional Bell
Operating Companies (RBOC's) curtailed capital spending during the third quarter
2001. As the prime construction season ends and resin prices continue to go
lower, the Company aggressively curtailed production in order to reduce pipe
inventory. However, plant operating rates resulted in $1 million less absorption
of fixed costs during the third quarter of 2001 when compared to the third
quarter of 2000. The Carlon business segment also had modestly lower gross
margins in both the current third quarter and year-to-date as the high density
polyethylene (HDPE) pipe products had lower selling prices than the prior year
as telecom market demand has dropped dramatically. Finally, Lamson Home Products
continues to earn better gross margins in 2001 compared to 2000 due to continued
progress on lowering product costs and the introduction of new products.







                                       10

Operating income for the third quarter of 2001 totaled $.6 million or .7% of net
sales. This compares to the prior year's third quarter operating income of $10.4
million or 11.8% of net sales. The reduced operating income is primarily a
result of the lower gross profit in the current quarter as operating expenses
were approximately the same in total dollars and as a percentage of net sales as
the third quarter of 2000.

Year-to-date operating income is $8.4 million in 2001 compared to $29.9 million
for the same period in 2000. Despite an increased sales level in the first three
quarters of 2001 and higher amortization charges, operating expenses were
reduced to 14.3% of net sales in the first three quarters of 2001 versus 15.9%
of net sales in the prior year period primarily to reductions in legal costs,
compensation expense, discretionary selling and marketing expenses and
settlement of litigation in the first quarter of 2001.

Net interest expense increased significantly compared with the prior year due to
an approximate $100 million increase in debt to fund the acquisitions completed
in 2000. Average borrowing rates were 6.77% in the third quarter of 2001 (6.84%
in the first three quarters of 2001) compared to 7.82% in the third quarter of
2000.

The income tax provision in the third quarter of 2001 reflects the impact of the
pretax loss on full year income estimates. The high income tax provision despite
nominal pretax income in the first nine months of 2001 is caused by the effect
of permanent unfavorable tax treatment of goodwill from the Pyramid acquisition.
The income tax provision for the first nine months of 2000 was 31.4%.

The Company's earnings before interest, taxes, depreciation and amortization
(EBITDA) was $5.1 million for the third quarter of 2001, and $21.8 million for
the first three quarters of 2001 compared with $12.9 million and $37.3 million
for the respective periods in 2000.

FINANCIAL CONDITION

Working capital was reduced to $50.0 million at the end of the current quarter,
which is $12.2 million lower than last year's third quarter and $8.3 million
lower than year-end 2000. During the first three quarters of 2001, the Company
generated $18.0 million of cash flows from operating activities compared to
$19.3 million for the first three quarters of 2000. The Company was able to
produce these positive cash flows despite the decline in net income, by
maintaining strong oversight of accounts receivable despite deteriorating
economic conditions and aggressively reducing the level of inventory.

Accounts receivable were $51.7 million at the end of the third quarter of 2001
compared to $56.7 million at year-end 2000 and $54.0 million outstanding at the
end of third quarter 2000. Days sales outstanding were about 54 days this
quarter which is comparable to both year-end 2000 and the prior year's third
quarter performance levels. The Company is experiencing slower payment from some
smaller telecom market customers due to the dramatic decrease in their wireless
activity this year.

At the end of the third quarter 2001 the Company had $44.9 million in inventory.
The inventory level is down $14.7 million or 25% from year-end 2000 and there is
similar reduction from third quarter of 2000. This decrease was the result of an
across-the-board inventory reduction effort in the second and third quarters of
2001 reacting to the softening demand. The Company was also able to achieve
higher inventory turn targets due to supply chain process improvements and
recent capital expenditures. The cost per pound of the primary raw material,
polyvinylchloride (PVC) resin in inventory is approximately 19% lower at the
end of the third quarter 2001 as compared with the same quarter of 2000 and 15%
lower than year-end 2000. Pounds of PVC resin inventory at the end of the third
quarter of 2001 have also declined by 30% and 23% compared to the end of the
third quarter of 2000 and year-end 2000, respectively. On an overall basis,
inventory turns improved to 5.5 times



                                       11
<PAGE>

at this quarter ending versus 3.8 times in the prior year quarter. The Company's
exposure to resin price volatility is reduced with the improved inventory turns.

Accounts payable have remained about the same as year-end 2000, despite the
usual seasonal growth expected in the third quarter, but are lower than the
prior year third quarter by $7 million due to the inventory reduction program
that significantly lowered the purchases of PVC and HDPE resins in the second
and third quarters of 2001.

The reduction in accrued expenses during the first three quarters of 2001
reflects revised expectations for compensation costs and annual customer sales
and marketing programs. In addition, the Company paid the remaining purchase
price and continued non-compete payments related to prior year acquisitions.

Capital expenditures totaled $6.1 million during the first three quarters of
2001. The expenditures were primarily for PVC, HDPE and flexible conduit
extrusion line capacity and productivity improvements that occurred in the first
few months of the year, the installation of radio-frequency (RF) technology at
the distribution centers and tooling for new product line development. The
Company anticipates spending a total of $9 million to $10 million for the full
year of 2001.

Based on current projected operating results for the year, the Company believes
cash flow from operations and its secured credit facility provide adequate
financing for general corporate purposes and the planned capital expenditures.
The Company has negotiated a second amendment to its credit facility which
resets various covenant levels through 2003 to reflect the lower earnings and
growth expectations in the current economic environment and lowers the secured
credit facility to $170 million of which $125 million represents a revolving
credit facility with the remainder in term debt. This amendment may increase the
Company's cost of borrowings under this agreement by an additional 50-100 basis
points through the term of the agreement.

OUTLOOK

The following paragraphs contain forward-looking comments. The comments are
subject to, and the actual future results may be impacted by, the cautionary
limitations and factors outlined in the following narrative comments.

The Company's sales have been supported by a very steady residential
construction base through the first three quarters of 2001. Housing starts are
expected to decline modestly the fourth quarter of 2001 through the first half
of 2002 from the 1.5 million unit level to closer to a 1.4 million unit level
before trending back up in the second half of 2002. These levels are still
fairly strong compared to previous economic downturns. Further interest rate
cuts should help maintain the level of existing home sales, which contributes to
home improvement product sales of Lamson Home Products.

The telecom infrastructure market spending remains weak as telephone and cable
TV companies capital spending plans continue to be deferred. This situation is
not expected to improve appreciably until no earlier than the second half of
2002 or the first half of 2003. Spending in this market is required long-term,
we believe, to build out the metropolitan rings, expand corporate and
institutional high-speed data and communications networks and to provide
broadband services to the home. The Company is exploring other areas, such as
gas collection, water drainage and sewer markets to better utilize its
manufacturing capacity while the telecom market remains soft.

We are advised that the cost of PVC resin may have hit a floor as PVC resin
manufacturing companies are expressing that they are selling resin for almost
their cash cost. This, along with reduced inventories channel-wide, should cause
a stabilization of pricing in the market. Additional PVC resin manufacturing
capacity



                                       12
<PAGE>

scheduled to be brought up the first part of 2002 along with the lower projected
U.S. construction activity the first half of next year, however, will keep the
pricing environment competitive. Improvement in the PVC Pipe segment may require
further substantial improvement in the export market, particularly in the
Pacific rim to absorb the current supply imbalance in the domestic market and
stabilize these costs.

The Company is reviewing several scenarios including the rationalization of
facilities, personnel and product lines in order to reduce fixed cost levels to
meet the challenges facing the Company heading into 2002.

The above statements contain expectations that are forward-looking statements
that involve risks and uncertainties within the meaning of the Private
Securities Litigation Reform Act of 1995. Actual results may differ materially
from those expected as a result of a variety of factors, such as: (i) the
volatility of resin pricing, (ii) the ability of the Company to pass through raw
material cost increases to its customers, (iii) maintaining a stable level of
housing starts, telecom infrastructure spending, consumer confidence and general
construction trends, and (iv) further deterioration in the country's general
economic condition affecting the markets for the Company's products.

ITEM 1 - LEGAL PROCEEDINGS
--------------------------

On September 23, 1999, the Company announced that a United States District Court
jury in the Northern District of Illinois found that the Company willfully
infringed on a patent held by Intermatic Incorporated of Spring Grove, Illinois,
relating to the design of an in-use weatherproof electrical outlet cover, and
awarded Intermatic $12.5 million in damages plus pre-judgment interest of
approximately $1.5 million. The court declined to increase the damages with
respect to the willfulness finding. The Company is pursuing a vigorous appeal
and believes it has meritorious positions that will substantially reduce or
eliminate the jury award. If, however, the appeal process is not successful, the
final resolution of the matter could have a material adverse affect on the
Company's financial position, cash flows and results of operations. This appeal
was heard on September 4, 2001 and it is expected that there will be a
resolution to this matter by the end of the first quarter of 2002.

During the first quarter of 2001, the Company settled its litigation against PW
Eagle and received a payment of $2.05 million, representing a partial recovery
of costs incurred in current and previous quarters, arising out of the failed
sale of the PVC Pipe segment in 1999.

The Company is also a party to various other claims and matters of litigation
incidental to the normal course of its business. Management believes that the
final resolution of these matters will not have a material adverse affect on the
Company's financial position, cash flows or results of operations.
