Item 1.01 - Entry Into a Material Definitive Agreement

     On August 15, 2007, Thomas & Betts Corporation, a Tennessee corporation
("Parent"), The Lamson & Sessions Co., an Ohio corporation (the "Company") and
T&B Acquisition II Corp., a wholly owned subsidiary of Parent and an Ohio
corporation ("Merger Sub") entered into an Agreement and Plan of Merger (the
"Merger Agreement"). The Merger Agreement provides that, upon the terms and
subject to the conditions set forth in the Merger Agreement, Merger Sub will
merge with and into the Company (the "Merger"), with the Company continuing as
the surviving corporation.

     At the effective time and as a result of the Merger, (i) the Company will
become a wholly owned subsidiary of Parent and (ii) each common share of the
Company will be converted into the right to receive $27.00 in cash, without
interest.

     Consummation of the Merger is subject to customary conditions, including
approval of the holders of the Company common stock and expiration or
termination of the applicable Hart-Scott-Rodino waiting period. The Merger
Agreement contains certain termination rights for both Parent and the Company,
and further provides that, upon termination of the Merger Agreement under
specified circumstances, (i) the Company may be required to pay Parent a
termination fee of $15,000,000 and (ii) Parent may be required to pay the
Company a termination fee of $4,000,000. The Merger Agreement has been included
to provide investors and security holders with information regarding its terms.
It is not intended to provide any other factual information about Parent or the
Company. The representations, warranties and covenants contained in the Merger
Agreement were made only for purposes of such agreement and as of specific
dates, were solely for the benefit of the parties to such agreement, and may be
subject to limitations agreed upon by the contracting parties, including being
qualified by confidential disclosures exchanged between the parties in
connection with the execution of the Merger Agreement. The representations and
warranties may have been made for the purposes of allocating contractual risk
between the parties to the agreement instead of establishing these matters as
facts, and may be subject to standards of materiality applicable to the
contracting parties that differ from those applicable to investors. Investors
are not third-party beneficiaries under the Merger Agreement and should not rely
on the representations, warranties and covenants or any descriptions thereof as
characterizations of the actual state of facts or condition of the Company,
Parent, Merger Sub or any of their respective subsidiaries or affiliates.
Moreover, information concerning the subject matter of the representations and
warranties may change after the date of the Merger Agreement, which subsequent
information may or may not be fully reflected in the Company's or Parent's
respective public disclosures.

     The foregoing description of the Merger Agreement does not purport to be
complete and is qualified in its entirety by reference to the Merger Agreement,
which is filed as Exhibit 2.1 hereto, and is incorporated into this report by
reference.
