      The following  constitutes  Amendment  No. 3 ("Amendment  No. 3") to the
Schedule  13D  filed by the  undersigned.  This  Amendment  No.  3 amends  the
Schedule 13D as specifically set forth.

      Item 2 is hereby amended to add the following:

            Lee D. Meyer has been withdrawn as a nominee for director.
Therefore, Mr. Meyer is no longer a Reporting Person.

            Michael Caporale,  Jr. is hereby added as Reporting Persons to the
Schedule 13D.

            Michael Caporale,  Jr. ("Mr. Caporale") is a nominee for the Board
of  Directors  of the  Issuer  and his  principal  occupation  is  acting as a
private  investor.  The  principal  business  address of Mr.  Caporale is 3668
Shetland  Trail,  Richfield,  Ohio  44286.  Mr.  Caporale  is a citizen of the
United States of America.

            No Reporting Person has, during the last five years, been convicted
in a criminal proceeding (excluding traffic violations or similar misdemeanors).
No Reporting Person has, during the last five years, been party to a civil
proceeding of a judicial or administrative body of competent jurisdiction and as
a result of such proceeding was or is subject to a judgment, decree or final
order enjoining future violations of, or prohibiting or mandating activities
subject to, federal or state securities laws or finding any violation with
respect to such laws.

      Item 3 is hereby amended and restated as follows:

            The Shares purchased by Starboard and Parche were purchased with the
working capital of such entities (which may, at any given time, include margin
loans made by brokerage firms in the ordinary course of business) in open market
purchases, except as otherwise noted, as set forth in Schedule A, which is
incorporated by reference herein. The aggregate purchase cost of the 1,569,338
Shares beneficially owned in the aggregate by all of the Reporting Persons is
approximately $35,741,459, including brokerage commissions.

      Item 4 is hereby amended to add the following:

            On April 26, 2007, Admiral Advisors delivered a letter to the
President and Chief Executive Officer of the Issuer (the "Proposal Letter")
expressing concern over the delay in scheduling the 2007 Annual Meeting and
requesting that the Issuer either:

            (a) promptly set a date for the 2007 Annual Meeting;

            or

            (b) immediately name two of Starboard's nominees to the Board of
                Directors of the Issuer.

            A copy of the Proposal Letter is attached hereto as Exhibit 10 and
is incorporated herein by reference.

----------------------                                    ----------------------


            On April 26, 2007, Ramius Capital issued a press release (the "Press
Release") relating to the Proposal Letter. The Press Release also announced that
Starboard filed preliminary proxy material with the Securities and Exchange
Commission (the "SEC") seeking to elect its nominees to the Board of Directors
of the Issuer. A copy of the Press Release is attached hereto as Exhibit 11 and
is incorporated herein by reference. Upon finalization of its proxy materials
and the filing of definitive proxy material with the SEC, Starboard intends to
solicit proxies from the shareholders of the Issuer in order to elect its
nominees as directors of the Issuer at the 2007 Annual Meeting.

            On April 26, 2007, Starboard delivered to the Issuer a supplement to
the Nomination Letter (the "Nomination Letter Supplement") withdrawing Mr. Meyer
as a nominee for election as a director at the 2007 Annual Meeting and
nominating Mr. Caporale as a substitute nominee. As further described in the
Nomination Letter Supplement, Mr. Meyer is currently serving on the board of
directors of a competitor of the Issuer, which was expected to be sold by the
end of April 2007; however, as a result of delays in the sale transaction, Mr.
Meyer decided to withdraw as a nominee for election as a director of the Issuer
at the 2007 Annual Meeting. A copy of the Nomination Letter Supplement is
attached hereto as Exhibit 12 and is incorporated herein by reference.

            STARBOARD STRONGLY ADVISES ALL SHAREHOLDERS OF THE ISSUER TO READ

IMPORTANT INFORMATION. SUCH DEFINITIVE PROXY STATEMENT WILL BE AVAILABLE AT NO
CHARGE ON THE SEC'S WEB SITE AT HTTP://WWW.SEC.GOV. IN ADDITION, THE

            As a result of the substitution of Mr. Caporale for Mr. Meyer as a
nominees for election at the 2007 Annual Meeting, on April 26, 2007, the
Reporting Persons entered into an Amended and Restated Joint Filing and
Solicitation Agreement in which, among other things, (a) the parties agreed to

respect to the securities of the Issuer to the extent required under applicable
securities laws, (b) the parties agreed to form the group for the purpose of
soliciting proxies or written consents for the election of the persons nominated
by Starboard to the Issuer's Board of Directors at the 2007 Annual Meeting and
for the purpose of taking all other actions incidental to the foregoing and (c)
Starboard and Parche shall have the right to pre-approve all expenses incurred
in connection with the group's activities and agreed to pay directly all such
pre-approved expenses on a pro rata basis between Starboard and Parche based on
the number of Shares in the aggregate held by each of Starboard and Parche on
the date hereof. A copy of this agreement is attached hereto as Exhibit 13 and
is incorporated herein by reference.

            Pursuant to a letter agreement, Starboard and Parche have agreed to

            Admiral Advisors has agreed to compensate Mr. Caporale for being

to allow Mr. Caporale to receive a profit participation with respect to the sale
by Admiral Advisors or its affiliates, as the case may be, of the last $20,000
worth of Shares (the "Participation Shares") beneficially owned by either
Admiral Advisors or its affiliates, as the case may be, to a third party
unaffiliated with any member of the Ramius Group. Pursuant to the terms of the
Compensation Letter Agreement, Mr. Caporale will be entitled to receive a cash
payment equal to the amount, if any, by which the proceeds received by Admiral
Advisors or its affiliates, as the case may be, from the sale of the
Participation Shares exceeds $20,000 in the aggregate. A form of the
Compensation Letter Agreement is attached hereto as Exhibit 15 and is
incorporated herein by reference.

ADMIRAL ADVISORS, LLC LETTERHEAD

April 26, 2007

Michael Merriman
The Lamson & Sessions Co.
President and CEO
25701 Science Park Drive
Cleveland, OH 44122

CC:   Board of Directors

Dear Michael,

April 28, 2007 marks the one year anniversary of last year's annual
shareholders' meeting of The Lamson & Sessions Co. (the "Company"). To our
knowledge, the Board of Directors of the Company (the "Board") has not yet set a
date for this year's annual meeting (the "2007 Annual Meeting"). We believe the
Board may have delayed scheduling the 2007 Annual Meeting because of the
exploration of strategic alternatives currently underway. We are supportive of
the Board's decision to hire Perella Weinberg to assist in this process.
However, it is not the Board's right to unilaterally decide for the Company's
shareholders that the current Board best represents the interests of the
shareholders during these pivotal times.

We request that the Company either promptly set the date for the 2007 Annual
Meeting so that shareholders may vote for who they believe will represent their
best interests (including our nominees as minority representatives on the Board
to assist in making these material decisions), or, alternatively, immediately
name two of our nominees to the Board to help the current Board members evaluate
what are likely complicated and weighty alternatives. Our request for minority
representation on the Board is reasonable, just, and frankly similar to what we
have suggested to you and the Board on several occasions in the past. We believe
such minority representation would add considerable value to the Board's
deliberations and would avoid an unnecessary proxy contest. We would expect our
two nominees to serve on a special committee of the Board with other independent
directors to work with Perella Weinberg in reviewing strategic alternatives.

Thank you for your consideration and, as always, we trust that the shareholders'
best interest will remain of paramount importance.

Best Regards,

/s/ Jeffrey C. Smith

Attn: Corporate Secretary

      Re:   NOTICE OF  INTENTION TO NOMINATE  SUBSTITUTE  NOMINEE FOR ELECTION
            AS  DIRECTOR  AT THE 2007 ANNUAL  MEETING OF  SHAREHOLDERS  OF THE
            LAMSON & SESSIONS CO.

Dear Sir:

      Reference is made to the letter from Starboard Value and Opportunity
Master Fund Ltd. ("Starboard") to The Lamson & Sessions Co. ("Lamson" or the
"Company"), dated February 12, 2007 (the "Original Nomination Letter"), relating
to Starboard's nomination of William J. Fox, Lee D. Meyer, Jeffrey C. Smith and
Jeffrey M. Solomon for election to the Board of Directors of Lamson (the "Lamson
Board") at the 2007 annual meeting of shareholders of Lamson, or any other
meeting of shareholders held in lieu thereof, and any adjournments,
postponements, reschedulings or continuations thereof (the "2007 Annual
Meeting"). This letter shall supplement and modify the Original Nomination
Letter by substituting Michael Caporale, Jr. for Lee D. Meyer as one of
Starboard's nominees for election at the 2007 Annual Meeting. Except as
specifically modified or supplemented by the information contained in this
supplemental notice, all information set forth in the Original Nomination Letter
remains applicable, including the Exhibits thereto, and the defined terms set
forth in the Original Nomination Letter are hereby incorporated herein by
reference.

      Starboard originally nominated Lee D. Meyer because of his industry and
transactional experience. As noted in the Original Nomination Letter, Mr. Meyer
is currently a member of the Board of Directors of PW Eagle, Inc., a competitor
of the Company in the PVC pipe market ("PWEI"), and Mr. Meyer expected to resign
from the PWEI board following the completion of the previously announced
acquisition of PWEI by J-M Manufacturing Company, Inc., (the "PWEI
Acquisition"), which was expected to be consummated shortly after approval by
PWEI's shareholders at a special shareholders' meeting on April 12, 2007.
However, PWEI recently announced that it received a second request from the
Federal Trade Commission (the "FTC") for information in connection with the
proposed PWEI Acquisition and that the PWEI Acquisition would be delayed until
at least 60 days after May 16, 2007, the date for compliance with the FTC's
second request. As a result the delay in the PWEI Acquisition, Mr. Meyer and
Starboard reconsidered Mr. Meyer's ability to stand for election at the 2007
Annual Meeting and agreed to withdraw Mr. Meyer as a nominee of Starboard for
election to the Lamson Board. Accordingly, Starboard hereby provides notice to
the Company of the withdrawal of Lee D. Meyer as a nominee for election at the
2007 Annual Meeting and of its intention to nominate Michael Caporale, Jr. as a
substitute nominee for election at the 2007 Annual Meeting.

----------------------                                    ----------------------


      This letter, including the Exhibits attached hereto, and the Original
Nomination Letter, including the Exhibits attached thereto, are collectively
referred to as the "Notice." If this Notice shall be deemed for any reason by a
court of competent jurisdiction to be ineffective with respect to the nomination
of Mr. Caporale at the 2007 Annual Meeting, or if Mr. Caporale shall be unable
to serve for any reason, this Notice shall continue to be effective with respect
to Starboard's remaining nominees and as to any replacement nominee(s) selected
by Starboard.

      Starboard continues to reserve the right to nominate additional nominees
for election as directors at the 2007 Annual Meeting to the extent that there
are in excess of four (4) vacancies on the Lamson Board to be filled by election
at the 2007 Annual Meeting or Lamson increases the size of the Lamson Board
above its existing size. Additional nominations made pursuant to the preceding
sentence are without prejudice to the position of Starboard that any attempt to
increase the size of the current Lamson Board or to reconstitute or reconfigure
the classes on which the current directors serve constitutes an unlawful
manipulation of Lamson's corporate machinery.

      Below please find information required by Regulation 14A of the Securities
Exchange Act of 1934, as amended (the "Exchange Act") and other information
concerning Mr. Caporale.

      MICHAEL CAPORALE, JR. (AGE 55) served as President, Chief Executive
Officer and a director of Associated Materials, Inc., a leading North American
manufacturer and distributor of exterior building products ("AMI"), from April
2002 until June 2006 and as Chairman of the Board of AMI from December 2004

Holdings ("AMH"), from March 2004 until June 2006. In December 2004, AMH sold a
50% equity interest in AMH to affiliates of Investcorp S.A. From 2000 until
April 2002, Mr. Caporale served as President and Chief Executive Officer of
AMI's Alside division. In April 2002, AMI was transitioned from a public company
to private ownership following the completion of a $436 million cash tender
offer by Harvest Partners, a private equity firm. Prior to joining AMI, from
1995 through 2000, Mr. Caporale served as President of Great Lakes Window, a
division of PlyGem Industries, Inc., a manufacturer of high-end vinyl windows

seventeen years in various operating positions in GE's Appliance, Jet Engine and
Transformer businesses. Mr. Caporale received a B.S. in Civil Engineering and an
M.B.A. from Syracuse University. The principal business address of Mr. Caporale
is 3668 Shetland Trail, Richfield, Ohio 44286. As of the date hereof, Mr.
Caporale does not own any securities of Lamson nor has he made any purchases or
sales of any securities of Lamson during the past two years.

      Starboard and certain other affiliates of Ramius Capital Group, L.L.C.
("Ramius Capital") have signed or intend to sign a letter agreement pursuant to
which they agree to indemnify Mr. Caporale against claims arising from the
solicitation of proxies from Lamson's shareholders in connection with the 2007
Annual Meeting and any related transactions.

("Admiral"), has signed or intends to sign a compensation letter agreement with
Mr. Caporale pursuant to which Admiral agrees to pay Mr. Caporale $5,000 in cash
upon the submission of this letter by Starboard to Lamson. Pursuant to such
compensation letter agreements, Admiral will also agree that upon the filing of
a definitive proxy statement with the Securities and Exchange Commission (the
"SEC") relating to a solicitation of proxies in favor of Mr. Caporale's election
as a director at the 2007 Annual Meeting, Admiral will allow Mr. Caporale to
receive a profit participation with respect to the sale by Admiral or its
affiliates of the last $20,000 worth of shares of Common Stock of Lamson
beneficially owned by Admiral to an unaffiliated third party.

      Other than as stated above, there are no arrangements or understandings
between Starboard and Mr. Caporale or any other person or persons pursuant to
which the nominations described herein are to be made, other than the consent by
Mr. Caporale to be named as a nominee in this Notice, to be named as a nominee
in any proxy statement filed by Starboard in connection with the solicitation of
Lamson shareholders and to serve as a director of Lamson, if so elected. Such
consent is attached hereto as EXHIBIT B.

                          Re: THE LAMSON & SESSIONS CO.

Dear Mr. _________:

      Thank you for agreeing to serve as a nominee for election to the Board of
Directors of The Lamson & Sessions Co. ("Lamson") in connection with the proxy
solicitation that Starboard Value and Opportunity Master Fund Ltd. and Parche,
LLC (collectively, the "Ramius Group") are considering undertaking to nominate
and elect directors at Lamson's 2007 annual meeting of stockholders, or any
other meeting of stockholders held in lieu thereof, and any adjournments,
postponements, reschedulings or continuations thereof (the "Ramius Group
Solicitation"). Your outstanding qualifications, we believe, will prove a
valuable asset to Lamson and all of its stockholders. This letter will set forth
the terms of our agreement.

      The members of the Ramius Group agree to jointly and severally indemnify
and hold you harmless against any and all claims of any nature, whenever
brought, arising from the Ramius Group Solicitation and any related
transactions, irrespective of the outcome; PROVIDED, however, that you will not
be entitled to indemnification for claims arising from your gross negligence,
willful misconduct, intentional and material violations of law, criminal actions
or material breach of the terms of this agreement; PROVIDED FURTHER, that this
indemnification agreement and all of the Ramius Group's obligations hereunder
shall not apply to any of your actions or omissions as a director of Lamson.
This indemnification will include any and all losses, liabilities, damages,
demands, claims, suits, actions, judgments, or causes of action, assessments,
costs and expenses, including, without limitation, interest, penalties,
reasonable attorneys' fees, and any and all reasonable costs and expenses
incurred in investigating, preparing or defending against any litigation,
commenced or threatened, any civil, criminal, administrative or arbitration
action, or any claim whatsoever, and any and all amounts paid in settlement of
any claim or litigation asserted against, resulting, imposed upon, or incurred
or suffered by you, directly or indirectly, as a result of or arising from the
Ramius Group Solicitation and any related transactions (each, a "Loss").

      In the event of a claim against you pursuant to the prior paragraph or the
occurrence of a Loss, you shall give the Ramius Group prompt written notice of
such claim or Loss (provided that failure to promptly notify the Ramius Group
shall not relieve us from any liability which we may have on account of this

Agreement, except to the extent we shall have been materially prejudiced by such
failure). Upon receipt of such written notice, the Ramius Group will provide you
with counsel to represent you. Such counsel shall be reasonably acceptable to
you. In addition, you will be reimbursed promptly for all Losses suffered by you
and as incurred as provided herein. The Ramius Group may not enter into any
settlement of loss or claim without your consent unless such settlement includes
a release of you from any and all liability in respect of such claim.

      You hereby agree to keep confidential and not disclose to any party,
without the consent of the Ramius Group, any confidential, proprietary or
non-public information (collectively, "Information") of the Ramius Group, its
affiliates or members of its Schedule 13D group which you have heretofore
obtained or may obtain in connection with your service as a nominee hereunder.
Notwithstanding the foregoing, Information shall not include any information
that is publicly disclosed by the Ramius Group, its affiliates or members of its
Schedule 13D group or any information that you can demonstrate is now, or
hereafter becomes, through no act or failure to act on your part, otherwise
generally known to the public.

      Notwithstanding the foregoing, if you are required by applicable law,
rule, regulation or legal process to disclose any Information you may do so
provided that you first promptly notify the Ramius Group so that the Ramius
Group or any member thereof may seek a protective order or other appropriate
remedy or, in the Ramius Group's sole discretion, waive compliance with the
terms of this Agreement. In the event that no such protective order or other
remedy is obtained or the Ramius Group does not waive compliance with the terms
of this Agreement, you may consult with counsel at the cost of the Ramius Group
and you may furnish only that portion of the Information which you are advised
by counsel is legally required to be so disclosed and you will request that the
party(ies) receiving such Information maintain it as confidential.

      All Information, all copies thereof, and any studies, notes, records,
analysis, compilations or other documents prepared by you containing such
Information, shall be and remain the property of the Ramius Group and, upon the
request of a representative of the Ramius Group, all such information shall be
returned or, at the Ramius Group's option, destroyed by you, with such
destruction confirmed by you to the Ramius Group in writing.

      This letter agreement shall be governed by the laws of the State of New
York, without regard to the principles of the conflicts of laws thereof.

[NAME OF NOMINEE]
[ADDRESS]
[Address]

Dear Mr. _________:

      This letter sets forth our mutual agreement with respect to compensation
to be paid to you for your agreement to be named and serve as a nominee of a
group of investors (the "Ramius Group"), including Admiral Advisors, LLC, a
subsidiary of Ramius Capital Group, L.L.C. ("Admiral"), for election as a
director of The Lamson & Sessions Co. (the "Company") at the Company's 2007
annual meeting of stockholders, or any other meeting of stockholders held in
lieu thereof, and any adjournments, postponements, reschedulings or
continuations thereof (the "Annual Meeting").

      1. CASH PAYMENT; PROFIT PARTICIPATION. In consideration of your agreement
         to be named and serve as nominee of the Ramius Group for election as a
         director of the Company at the Annual Meeting, the undersigned hereby
         agrees to (i) pay you $5,000 in cash upon the Ramius Group submitting a
         letter to the Company nominating you for election as a director of the
         Company (with such payment to be made as soon as reasonably practicable
         after you have been nominated) and (ii) in the event the Ramius Group
         files a definitive proxy statement with the U.S. Securities and
         Exchange Commission (the "Proxy Statement") relating to a solicitation
         of proxies in favor of your election as a director of the Company at
         the Annual Meeting (the date of such filing being hereinafter referred
         to as the "Proxy Filing Date"), to allow you to receive a profit
         participation with respect to the sale by Admiral or its affiliates, as
         the case may be, of the last $20,000 worth of shares of the Company's
         common stock (the "Participation Shares") beneficially owned by Admiral
         to a third party unaffiliated with any member of the Ramius Group. The
         number of Participation Shares shall be determined by dividing $20,000
         by the closing price of the Company's common stock on the Proxy Filing
         Date (the "Proxy Date Closing Price"). Your profit participation shall
         entitle you to receive a cash payment equal to the amount, if any, by
         which the proceeds received by Admiral or its affiliates, as the case
         may be, from the sale of the Participation Shares exceeds $20,000 in
         the aggregate (the "Contingent Payment").

      2. RIGHTS AS A STOCKHOLDER. Your right to receive the Contingent Payment
         shall not entitle you to any rights as a stockholder of the Company,
         including, without limitation, any voting rights or disposition rights
         with respect to the Participation Shares.

----------------------                                    ----------------------


      3. FORFEITURE OF PROFIT PARTICIPATION. The profits related to the
         Participation Shares will be paid to you in all circumstances upon and
         subject to the sale of the Participation Shares except (i) if you are
         not named in the Proxy Statement or if you withdraw your consent to
         serve as a director nominee of the Ramius Group after the filing of the
         Proxy Statement, (ii) if elected to the Company's Board of Directors,
         you voluntarily cease to serve as a director of the Company prior to
         the expiration of your term, (iii) if you are in breach of your
         obligations under the indemnification agreement between us.

      4. NON-TRANSFERABILITY. Your right to the profits related to the
         Participation Shares is non-transferable.

      5. ENTIRE AGREEMENT. AMENDMENT. This letter agreement contains the entire
         agreement between you and the undersigned and supersedes other oral and
         written agreements previously entered into by you and the undersigned
         concerning the same subject matter. This letter agreement may be
         modified or rescinded only with the written consent of both parties.

      6. GOVERNING LAW. The validity, interpretation, construction and
         performance of this letter agreement shall be governed by the laws of
         the State of New York, without regard to its principles of conflict of
         laws, and by applicable laws of the United States. The parties hereto
         consent to the jurisdiction of the New York State and United States
         courts located in New York County, New York for the resolution of any
         disputes hereunder and agree that venue shall be proper in any such
         court notwithstanding any principle of forum non conveniens and that
         service of process on the parties hereto in any proceeding in any such
         court may be effected in the manner provided herein for the giving of
         notices. The parties hereto waive trial by jury in respect of any such
         proceeding.

      7. BINDING EFFECT. This letter agreement shall bind and inure to the
         benefit of you and your heirs, successors and assigns. If Admiral
         transfers all of the Company's common stock owned by it to an
         affiliate, Admiral, as a condition thereof, shall cause such affiliate
         to assume the obligations of Admiral under this letter agreement.

      8. COUNTERPARTS. This letter agreement may be executed in counterparts,
         each of which shall be deemed an original, and all of which, taken
         together, shall constitute one and the same instrument.
