             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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. (the "Company") Deferred
Savings Plan (the "Plan") as of December 31, 2004 and 2003 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 of the Public
Company Accounting Oversight Board (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. The Plan is not required
to have, nor were we engaged to perform, an audit of its internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Plan's internal control over financial
reporting. Accordingly, we express no such opinion. An audit includes examining,
on a test basis, evidence supporting the amounts and disclosures in the
financial statements, 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.

As described in Note B, these financial statements and supplemental schedule
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.

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, 2004 and 2003 and changes
in its net assets available for benefits for the years then ended in conformity
with the modified cash basis of accounting.

Our audit was performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule (modified cash
basis) of assets held at end of year as of December 31, 2004 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 schedule is the
responsibility of the Plan's management. The supplemental schedule has been
subjected to the auditing procedures applied in the audit of the basic financial
statements for the year ended December 31, 2004 and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

                THE LAMSON & SESSIONS CO. DEFERRED SAVINGS PLAN

NOTES TO THE FINANCIAL STATEMENTS

                           DECEMBER 31, 2004 AND 2003

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 Industries II, Inc. 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) as amended. 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 ("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, 2005, participants can contribute 1% to
      100% of their eligible compensation.

      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.

NOTES TO THE FINANCIAL STATEMENTS

                           DECEMBER 31, 2004 AND 2003

NOTE A - DESCRIPTION OF PLAN - CONTINUED

      2.    CONTRIBUTIONS - CONTINUED

      In addition, the Company can make discretionary matching contributions.
      Based on the Company's annual financial performance, the Company may make
      an additional matching contribution. This additional matching
      contribution, if any, will be a percentage as determined by the Board of
      Directors or its delegate and is initially invested in Lamson & Sessions
      stock. Participants are 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.

      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. Allocations are based on
      participant earnings or account balances, as defined. The benefit to which
      a participant is entitled is the benefit that can be provided from the
      participant's vested account.

      4.    VESTING

      Participants are immediately vested in their voluntary 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.

NOTE A - DESCRIPTION OF PLAN - CONTINUED

      5.    PARTICIPANT LOANS

      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 5.27 percent to 10.74 percent.

      6.    PAYMENT OF BENEFITS

      On termination of service due to death, disability or retirement, a
      participant may elect to receive an amount equal to the value of the
      participant's vested interest in his or her account in either a lump-sum
      amount, or in annual installments. Withdrawals from a participant's
      account may be made prior to termination, subject to certain restrictions
      as defined by the Plan.

      7.    PLAN EXPENSES

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

      8.    FORFEITURES

      Forfeited non-vested accounts are used to reduce employer contributions.
      In 2004 and 2003, the amount of forfeited non-vested accounts which were
      applied to reduce such contributions were $36,931 and $62,179,
      respectively.

      9.    OTHER

      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. Additional investments in insurance are no longer
      permitted.

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 except for participant
      loans and life insurance contracts. 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 are valued at their
      outstanding principal balance, which approximates fair value. Life
      insurance contracts are valued at cash surrender 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 of assets,
      liabilities and changes therein, and disclosure of contingent assets and
      liabilities. Actual results could differ from those estimates.

                THE LAMSON & SESSIONS CO. DEFERRED SAVINGS PLAN

NOTES TO THE FINANCIAL STATEMENTS

                           DECEMBER 31, 2004 AND 2003

NOTE D - TAX STATUS

      The Internal Revenue Service has determined and informed the Company by a
      letter dated May 7, 2002, that the Plan was designed in accordance with
      applicable sections of the Internal Revenue Code (IRC). Although the Plan
      has been amended since receiving the determination letter, the Plan
      administrator and Plan's tax counsel believe the Plan is designed and is
      currently operated in compliance with applicable requirements of the IRC.
      Therefore, no provision for income taxes has been included in the Plan's
      financial statements.

NOTE E - PLAN TERMINATION

      Although it has not expressed any intent to do so, the Company has the
      right under the Plan to discontinue its contributions at any time and to
      terminate the Plan subject to the provisions of ERISA. In the event of
      Plan termination, participants will immediately become 100% vested in
      their accounts.

NOTE F - RELATED PARTY TRANSACTIONS

      The Lamson & Sessions Stock Fund invests in Lamson & Sessions Co. common
      stock, which is traded on the New York Stock Exchange under the symbol
      LMS. The fund maintains short-term cash sufficient to meet its estimated
      daily cash needs. The fund purchases shares of Lamson & Sessions Co.
      common stock on the open market at open market prices. Transactions in the
      fund qualify as permitted party-in-interest transactions.

NOTE G - RISKS AND UNCERTAINTIES

      The Plan invests in various investment securities. Investment securities
      are exposed to various risks such as interest rate, market, and credit
      risks. Due to the level of risk associated with certain investment
      securities, it is at least reasonably possible that changes in the values
      of investment securities will occur in the near term and that such changes
      could materially affect participants' account balances and the amounts
      reported in the statement of net assets available for benefits.
