                          INDEPENDENT AUDITOR'S REPORT



To the Board of Directors
The Lamson & Sessions Co.

We have audited the accompanying statements of net assets available for benefits
- modified cash basis of The Lamson & Sessions Co. Deferred Savings Plan as of
December 31, 2002 and 2001, and the related statements of changes in net assets
available for benefits - modified cash basis for the years then ended. These
financial statements are the responsibility of the Plan's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. 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 audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of The Lamson &
Sessions Co. Deferred Savings Plan as of December 31, 2002 and 2001, and changes
in its net assets available for benefits for the years then ended in conformity
with the modified cash basis of accounting.

As described in Note B, these financial statements were prepared on a modified
cash basis of accounting, which is a comprehensive basis of accounting other
than generally accepted accounting principles in the United States.

Our audits of the Plan's financial statements as of and for the years ended
December 31, 2002 and 2001 were conducted for the purpose of forming an opinion
on the basic financial statements taken as a whole. The supplemental schedule of
assets held for investment purposes as of and for the year ended December 31,
2002, referred to as "supplemental information", is presented for the purpose of
additional analysis and is not a required part of the basic financial statements
but is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental information is the responsibility of the
Plan's management. The supplemental information has been subjected to the
auditing procedures applied in the audit of the basic financial statements for
the year ended December 31, 2002, and in our opinion, is fairly stated in all
material respects in relation to the financial statements taken as a whole.

NOTES TO THE FINANCIAL STATEMENTS
-------------------------------------------------------------------------------

                           DECEMBER 31, 2002 AND 2001

NOTE A - DESCRIPTION OF PLAN

         The following description of The Lamson & Sessions Co. (the "Company")
         Deferred Savings Plan (the "Plan") provides only general information.
         Participants should refer to the Plan agreement for a more complete
         description of the Plan's provisions.

         1.        GENERAL

         The Plan is a defined contribution plan covering substantially all
         employees of the Company. Employees are eligible to participate in the
         Plan on the first day of the calendar quarter after which they have
         attained the age of 21 (age 18 for Pyramid salaried and non-union
         hourly employees) and completed one-half (1/2) year of service. The
         Plan is subject to the provisions of the Employee Retirement Income
         Security Act of 1974 (ERISA). The Company is the Plan's administrator.
         The 401(k) Company is the Plan's record keeper. The Plan's custodian is
         the Pershing Division of Donaldson, Lufkin & Jenrette Securities
         Corporation which was acquired by Credit Suisse First Boston in
         November 2000 ("Pershing").

         2.        CONTRIBUTIONS

         Each year, participants contribute 1% to 15% of their eligible
         compensation (pre-tax contributions), as defined in the Plan. The
         Company contributes a matching contribution equal to 50% of the
         participant's contribution, not to exceed 6% of the participant's
         compensation for any plan year.

         Effective January 1, 2000 for each salaried participant for whom a
         salary reduction contribution has been made, the employer shall also
         contribute an additional matching contribution equal to 25% of such
         salary reduction contribution, up to the first 6% of the participant's
         contribution. This additional contribution is required to be
         contributed or initially invested in the Lamson & Sessions Stock Fund.
         Immediately following such contribution or initial investment in stock,
         the participant shall have the ongoing option to redirect the
         investment of such matching contributions among the investment options
         available under the Plan.

         In addition, the Company can make discretionary matching contributions.
         Based on the Company's annual financial performance the Company may
         make a profit-sharing matching contribution. This profit-sharing match,
         if any, can add as much as an additional 25% of the participant's
         contribution up to the first 6% of compensation and is initially
         invested in Lamson & Sessions stock. A participant is also eligible to
         receive an additional discretionary matching contribution if they were
         employed with the Company on the last day of the Plan year for which
         the contribution is made and they have completed one year of service
         during the Plan year.

NOTE A - DESCRIPTION OF PLAN - CONTINUED

         3.        PARTICIPANT ACCOUNTS

         Each participant's account is credited with the participant's elective
         contributions, allocations of the Company's contributions and earnings
         on those contributions. Forfeitures due to the distribution of a
         participant's account before the participant has become fully vested
         reduce subsequent company contributions. The benefit to which a
         participant is entitled is the benefit that can be provided from the
         participant's vested account.

         Participants may direct their individual account balances as of
         December 31, 2002 among the following investment options:

NOTES TO THE FINANCIAL STATEMENTS
------------------------------------------------------------------------------

                           DECEMBER 31, 2002 AND 2001

NOTE A - DESCRIPTION OF PLAN - CONTINUED

         3.       PARTICIPANT ACCOUNTS - CONTINUED

                  Fidelity Advisor Equity Growth Fund - This fund seeks to
                  achieve capital appreciation by investing primarily in common
                  stock of companies with above-average characteristics.

                  Putnam International Voyager Fund - This fund seeks long-term
                  capital appreciation by investing primarily in equity
                  securities of small and mid-capitalization companies whose
                  principle place of business is located outside of the United
                  States or whose securities are principally traded on foreign
                  markets.

                  Lamson & Sessions Stock Fund - Funds are invested in common
                  stock of the The Lamson & Sessions Co. The Fund's objective is
                  to provide investment returns linked to Lamson & Sessions'
                  long-term capital appreciation and offer employees a
                  convenient way to invest in Lamson & Sessions' stock.

         In addition, subject to the terms of the Plan, participants with
         sufficient vested balances may borrow from their fund accounts.
         Participant loans are treated as an additional investment option under
         the terms of the Plan.

         Prior to January 1, 1998, the Plan also offered participants the option
         to invest in life insurance. Participants with portions of their
         accounts invested in life insurance at January 1, 1998 have the option
         of keeping the insurance in place, but additional investments in
         insurance are no longer permitted.

         Effective January 1, 2002 salaried and non-union hourly employees of
         Pyramid Industries, Inc., a subsidiary of the Company, who attained age
         18 and had completed six months of service became eligible to
         participate in the Plan. Effective July 1, 2002 union hourly employees
         of Pyramid Industries, Inc. who obtained age 21 and had completed six
         months of service became eligible to participate in the Plan. Effective
         August 1, 2002, the Pyramid Industries II, Inc. Retirement Plan and the
         Pyramid Industries, Inc. Union Employees Profit Sharing Plan were
         merged with and into the Plan to form a single plan. Total assets
         merged from the Pyramid Plans were $888,245.

NOTES TO THE FINANCIAL STATEMENTS
-------------------------------------------------------------------------------

                           DECEMBER 31, 2002 AND 2001

NOTE A - DESCRIPTION OF PLAN - CONTINUED

         4.        VESTING

         Participants are immediately vested in their contributions plus actual
         earnings thereon. Vesting in the Company's matching and discretionary
         contribution portions of their accounts plus actual earnings thereon is
         based on Years of Service as defined by plan provisions. A participant
         is fully vested after five years.

         5.        PARTICIPANT LOANS RECEIVABLE

         Participants may borrow from their fund accounts a minimum of $1,000
         and a maximum equal to the lesser of $50,000 or 50 percent of their
         vested balance in all their accounts reduced by their highest
         outstanding loan balance within the twelve (12) preceding months. Loan
         transactions are treated as transfers to (from) the investment fund
         from (to) the Participant Notes fund. A loan must be repaid through
         payroll withholding, the repayments must be periodic, and the term must
         not exceed five (5) years unless the proceeds are used to acquire a
         home. Such loans can be repaid over a maximum of fifteen (15) years.
         The loans are secured by the balance in the participant's account and
         bear interest at a rate commensurate with local prevailing rates as
         determined by the trustees on the date the loan is made. Interest rates
         currently charged on outstanding balances range from 6.00 percent to
         10.84 percent.

         6.        PAYMENT OF BENEFITS

         Benefits upon retirement, death or other termination of employment may
         be paid either in a lump sum or in periodic payments. Withdrawals from
         a participant's account may be made prior to termination, subject to
         certain restrictions.

         7.        PLAN EXPENSES

         The Lamson & Sessions Co. absorbs all costs to administer the Plan.

         8.        FORFEITURES

         Forfeited nonvested accounts are used to reduce employer contributions.
         In 2002 and 2001, the amount of forfeited nonvested accounts which were
         applied to reduce such contributions were $68,689 and $36,980,
         respectively.

NOTE B - SUMMARY OF ACCOUNTING POLICIES

         1.       BASIS OF ACCOUNTING

         The financial statements of the Plan are prepared under the modified
         cash basis of accounting. Under this basis, contributions which are
         withheld by the plan sponsor but not allocated to participant accounts
         at year end are recorded as a receivable. In addition pending trades
         and certain withholdings are included in accrued expenses.

         2.       INVESTMENT VALUATION AND INCOME RECOGNITION

         The Plan's investments are stated at fair value. Shares of registered
         investment companies are valued at quoted market prices which represent
         the net asset value of shares held by the Plan at year-end. The Company
         stock is valued at its quoted market price. Participant loans
         receivable are valued at their outstanding principal balance. Life
         insurance contracts are valued at cash value.

         Purchases and sales of securities are recorded on a trade-date basis.
         Interest and dividend income is recorded when received.

         3.       PAYMENT OF BENEFITS

         Benefits are recorded when paid.

         4.       USE OF ESTIMATES

         The preparation of financial statements, in conformity with the
         modified cash basis of accounting, requires the plan administrator to
         make estimates and assumptions that affect certain reported amounts and
         disclosures. Actual results could differ from those estimates.
