                STARBOARD VALUE AND OPPORTUNITY MASTER FUND LTD.

                              ______________, 2007

Dear Fellow Shareholder:

      Starboard Value and  Opportunity  Master Fund Ltd.  ("Starboard")  and the
other participants in this solicitation  (collectively,  the "Ramius Group") are
the beneficial owners of an aggregate of 1,569,338 shares of Common Stock of The
Lamson & Sessions Co.  ("Lamson" or the "Company"),  representing  approximately
9.9% of the outstanding  shares of common stock of the Company.  For the reasons
set forth in the attached Proxy Statement, the Ramius Group wants to ensure that
the Board of Directors  of Lamson is fully and  adequately  exploring  strategic
alternatives as the Company has run two strategic  review  processes in the past
that  failed to yield a sale or  disposition  of either the  Company's  PVC Pipe
business or the entire Company. Additionally, the Ramius Group believes that the
nominees it has  proposed  for  election to the Lamson  Board of  Directors  are
better suited than the Company's nominees to implement  necessary  strategic and
operational  changes  should the  Company's  strategic  alternatives  review not
result in a sale of the  Company.  The Ramius  Group is  therefore  seeking your
support  at  the  annual  meeting  of  shareholders  scheduled  to  be  held  at
________________________________________________  on ________  __, 200, at __:__
_.M. (local time) for the following:

            To  elect  Starboard's  slate  of  four  nominees  to the  Board  of
            Directors to serve as Class I directors.

      The Ramius Group urges you to carefully consider the information contained
in the attached Proxy Statement and then support its efforts by signing,  dating
and returning the enclosed WHITE proxy card today.  The attached Proxy Statement
and the enclosed WHITE proxy card are first being furnished to the  shareholders
on or about _____________, 2007.

      If you have already voted for the  incumbent  management  slate,  you have
every right to change your vote by signing,  dating and  returning a later dated
proxy.

      If you have any questions or require any assistance with your vote, please
contact  MacKenzie  Partners,  Inc., which is assisting us, at their address and
toll-free numbers listed on the following page.

      Thank you for your support.

                                 PROXY STATEMENT

                STARBOARD VALUE AND OPPORTUNITY MASTER FUND LTD.

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

         PLEASE SIGN, DATE AND MAIL THE ENCLOSED WHITE PROXY CARD TODAY

      Starboard  Value  and  Opportunity  Master  Fund  Ltd.,  a Cayman  Islands
exempted  company  ("Starboard"),  is a significant  shareholder of The Lamson &
Sessions  Co., an Ohio  corporation  ("Lamson" or the  "Company").  Starboard is
writing to you in connection  with the election of four nominees to the board of
directors of Lamson (the "Lamson  Board") at the annual meeting of  shareholders
scheduled to be held at _______________________________________ on _________ __,
2007, at __:__ _.M. (local time),  including any  adjournments or  postponements
thereof  and any  meeting  which  may be  called in lieu  thereof  (the  "Annual
Meeting").  This proxy statement (this "Proxy Statement") and the enclosed WHITE
proxy card are first being furnished to  shareholders  on or about  ___________,
2007.

      This Proxy Statement and the enclosed WHITE proxy card are being furnished
to shareholders  of Lamson by Starboard in connection  with the  solicitation of
proxies from Lamson's shareholders for the following:

      To elect Starboard's director nominees,  Michael Caporale, Jr., William J.
      Fox,  Jeffrey C. Smith and Jeffrey M. Solomon (the "Ramius  Nominees")  to
      serve as Class I  directors  of the  Company,  in  opposition  to Lamson's
      incumbent directors whose terms expire at the Annual Meeting.

      Starboard,  Parche,  LLC, a Delaware limited liability company ("Parche"),
Admiral   Advisors,   LLC,  a  Delaware  limited   liability  company  ("Admiral
Advisors"),  Ramius Capital Group,  L.L.C., a Delaware limited liability company
("Ramius  Capital"),  C4S & Co., L.L.C., a Delaware  limited  liability  company
("C4S"), Peter A. Cohen ("Mr. Cohen"),  Morgan B. Stark ("Mr. Stark"), Thomas W.
Strauss ("Mr. Strauss"),  Jeffrey M. Solomon ("Mr.  Solomon"),  Jeffrey C. Smith
("Mr.  Smith"),  William J. Fox ("Mr.  Fox") and  Michael  Caporale,  Jr.  ("Mr.
Caporale")  are  members  of a group  (the  "Ramius  Group"  or "we")  formed in
connection  with this proxy  solicitation  and are deemed  participants  in this
proxy solicitation.

      Ohio law  generally  provides that  shareholders  have  cumulative  voting
rights  with  respect  to the  election  of  directors  if written  notice  that
cumulative voting is desired is given to the President,  a Vice President or the
Secretary of the company at least  forty-eight  hours before the Annual Meeting.
We intend to give such written  notice to invoke our right to cumulate votes for
the election of the Ramius  Nominees.  Cumulative  voting rights  entitle you to
give a  nominee  as many  votes as is  equal to the  number  of  shares  you own




multiplied by the number of directors to be elected,  or you may distribute your
votes among the  nominees as you see fit. We are  soliciting  the  discretionary
authority to cumulate votes,  and the persons named as proxies on our proxy card
will have the  authority  to cumulate  votes at their  discretion  at the Annual
Meeting.  We will use the  authority  granted to us by the enclosed  WHITE proxy
card to  cumulate  votes at our  discretion  for all or a portion  of the Ramius
Nominees  in order to assure  that the  maximum  number of Ramius  Nominees  are
elected to the Lamson Board.

      Lamson has set the record date for  determining  shareholders  entitled to
notice of and to vote at the Annual Meeting as ______________, 2007 (the "Record
Date").  The mailing  address of the  principal  executive  offices of Lamson is
25701 Science Park Drive, Cleveland,  Ohio 44122.  Shareholders of record at the
close of  business  on the Record  Date will be  entitled  to vote at the Annual
Meeting.  According to Lamson,  as of the Record Date, there were  _____________
shares of common stock, no par value per share (the  "Shares"),  outstanding and
entitled to vote at the Annual  Meeting.  As of the date hereof,  the members of
the Ramius Group are the beneficial  owners of an aggregate of 1,569,338 Shares,
which  represents  approximately  9.9%  of  the  Shares  outstanding  (based  on
information  publicly  disclosed  by the  Company).  The  participants  in  this
solicitation  intend  to  cumulate  votes in  respect  of such  Shares  at their
discretion  for all or a portion of the Ramius  Nominees in order to assure that
the maximum number of Ramius Nominees are elected to the Lamson Board.

THIS  SOLICITATION  IS BEING MADE BY THE  RAMIUS  GROUP AND NOT ON BEHALF OF THE
BOARD OF DIRECTORS OR MANAGEMENT OF LAMSON. THE RAMIUS GROUP IS NOT AWARE OF ANY
OTHER MATTERS TO BE BROUGHT  BEFORE THE ANNUAL  MEETING.  SHOULD OTHER  MATTERS,

SOLICITATION, BE BROUGHT BEFORE THE ANNUAL MEETING, THE PERSONS NAMED AS PROXIES
IN THE ENCLOSED WHITE PROXY CARD WILL VOTE ON SUCH MATTERS IN THEIR DISCRETION.

THE RAMIUS  GROUP  URGES YOU TO SIGN,  DATE AND  RETURN THE WHITE  PROXY CARD IN
FAVOR OF THE ELECTION OF ITS NOMINEES.

                           BACKGROUND TO SOLICITATION

      We are significant  shareholders of the Company.  The Ramius Group owns in
the aggregate  1,569,338 Shares,  representing  approximately 9.9% of the issued
and outstanding common stock of the Company,  which Shares were purchased in the
open market, except as otherwise noted on Schedule I, for a total purchase price
of approximately $35,741,459, including brokerage commissions.

      The  following  is a  chronology  of  events  leading  up  to  this  proxy
solicitation:

      o  On November 28 and 29, 2006, certain  representatives of Ramius Capital
         met with Lamson's Chief Financial  Officer to discuss the merits of the
         Company's  stated  strategy of pursuing  acquisitions to diversify away
         from the PVC Pipe business  especially in light of the possibility that
         such acquisitions could be executed at multiples  significantly  higher
         than where Lamson trades on a  stand-alone  basis.  The Ramius  Capital
         representatives  specifically  questioned  the  actions  taken  by  the
         Company to 1) expand the Company's credit facility from $125 million to
         $250  million and 2) call a special  shareholder  meeting to double the
         authorized  shares of the Company from 20 million  shares to 40 million
         shares.

      o  On December 4, 2006, Admiral Advisors,  an affiliate of Ramius Capital,
         delivered a letter to Lamson's  President and Chief  Executive  Officer
         expressing its belief that the Shares are significantly undervalued and
         highlighting several concerns about certain aspects of the strategy and
         direction  of the Company.  Admiral  Advisors  expressed  its view that
         shareholder  value  would  be  significantly  enhanced  if the  Company
         executed a sale of the Company's PVC Pipe business and  repurchased $60
         million - $120 million of its outstanding shares of common stock.

      o  On December 15, 2006,  certain  representatives  of Ramius  Capital met
         with  Lamson's  President  and Chief  Executive  Officer  and its Chief
         Financial  Officer to discuss  their  concerns  regarding the Company's
         strategy  and  the  prospects  for a sale  of the  Company's  PVC  Pipe
         business.

      o  On January 18, 2007,  Admiral  Advisors  delivered a letter to Lamson's
         President and Chief  Executive  Officer and the Lamson Board urging the
         Lamson Board to immediately  hire a reputable  investment bank to fully
         explore  all  strategic  alternatives  to maximize  shareholder  value,
         including  both a sale of the Company's PVC Pipe business and a sale of
         the Company.  Admiral Advisors also stated in the letter that it wanted
         to discuss  immediate  representation  on the Lamson Board,  and in the
         event an  agreement  could  not be  reached  on  Board  representation,
         Admiral  Advisors  stated that it intended  to nominate  directors  for
         election at the Annual Meeting.


                                      -4-


      o  On February 12, 2007, Lamson issued a press release  announcing that it
         had engaged Perella Weinberg Partners, an independent  investment bank,
         to  assist  the  Lamson  Board and  management  of the  Company  in the
         evaluation of the Company's strategic and financial alternatives.

      o  On February 12, 2007, Starboard delivered a letter to Lamson nominating
         William J. Fox,  Lee D. Meyer,  Jeffrey C. Smith and Jeffrey M. Solomon
         for election to the Lamson Board at the Annual Meeting.

      o  On  February  13,  2007,  certain  representatives  of  Ramius  Capital
         traveled to Cleveland,  Ohio to meet with several members of the Lamson
         Board and  Lamson's  senior  management  to discuss  appropriate  Board
         representation  without the necessity of a proxy contest.  However, the
         Ramius Capital  representatives  were unable to reach an agreement with
         Lamson.

      o  On April 26, 2007,  Starboard delivered a supplemental letter to Lamson
         substituting  Michael  Caporale,  Jr.  for Lee D.  Meyer  as one of its
         nominees for election to the Lamson  Board at the Annual  Meeting.  The
         reason for such substitution,  as described in the supplemental letter,
         was  that  Mr.  Meyer  is a  member  of the  board  of  directors  of a
         competitor of the Company,  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.

      o  On April 26, 2007, Admiral Advisors delivered a letter to the President
         and Chief Executive Officer of the Company  expressing concern over the
         delay in scheduling  the 2007 Annual  Meeting and  requesting  that the
         Company  either  promptly  set a date for the 2007  Annual  Meeting  or
         alternatively,  immediately  name  two of the  Ramius  Nominees  to the
         Lamson Board.

                                    PROPOSAL

                              ELECTION OF DIRECTORS

      The  Lamson  Board  is  divided  into  three  classes  serving   staggered
three-year  terms and the term of the Class I directors of the Lamson Board will
expire at the Annual Meeting. On December 8, 2006, the Lamson Board expanded the
size of the Board from nine directors to ten and elected  William E.  MacDonald,
III to fill the vacancy created by such expansion.  The Company's public filings
do not specify to which class Mr.  MacDonald  was elected.  In a filing with the
Securities  and Exchange  Commission  (the "SEC") on April 21, 2006, the Company
reported  that  John B.  Schulze,  a Class III  director  and  Lamson's  current
Chairman  of the  Board,  notified  Lamson  that he  would  retire  from all his
positions at Lamson,  including  director,  no later than the Annual Meeting and
the  Company  reiterated  that  position  in an SEC filing on  November 1, 2006.
However,  in an SEC filing on March 15,  2007,  the  Company  reported  that Mr.
Schulze  will  continue to serve as  non-executive  Chairman of the Lamson Board
following the Annual Meeting. Taking into consideration the foregoing, it is the
Ramius Group's belief that four Class I directors of the Lamson Board will stand
for  election  at the  Annual  Meeting.  In the event that the number of Class I
directors to stand for election at the Annual  Meeting is less than four and one
or more directors of another class will stand for election,  then one or more of
the Ramius  Nominees,  as  appropriate,  will be deemed to stand for election to
such other class or classes.


                                      -5-


      The Ramius Group is seeking  your  support at the Annual  Meeting to elect
the Ramius  Nominees in opposition  to Lamson's  director  nominees.  The Ramius
Group is  soliciting  the  discretionary  authority to cumulate  votes,  and the

                          REASONS FOR THE SOLICITATION

      WE BELIEVE THE PVC PIPE BUSINESS DIMINISHES THE VALUE OF THE COMPANY,
                       AND THAT IT SHOULD AND CAN BE SOLD.

      For the  reasons  outlined  below,  we  believe  it  would  be in the best
interests  of the Lamson  shareholders  for  management  and the Lamson Board to
expeditiously explore and consummate a sale of the PVC Pipe business in order to
focus on the core  business  opportunities  within the  Carlon  and Lamson  Home
Products  businesses.  We believe the Company's recent announcement that it will
consider strategic  alternatives is a step in the right direction,  particularly
if it  represents a bona fide  intention  to seriously  pursue a sale of the PVC
Pipe business or a sale of the entire Company for an acceptable premium.

      However,  we  are  concerned  about  management  and  the  Lamson  Board's
commitment  to  consummating  a  transaction.  In fact,  the  Lamson  Board  has
conducted two sales  processes  that did not yield a sale of either the PVC Pipe
business  or the entire  Company.  In  December  1998,  following  a  previously
announced strategic  evaluation process, the Company agreed to sell the PVC Pipe
business  to Eagle  Pacific  Industries,  Inc.;  however,  that  sale was  never
consummated.  In October  2004,  the Company  retained  Brown,  Gibbons,  Lang &
Company as its financial  advisor to explore strategic  alternatives,  including
the possible sale of the Company, but no transaction was completed.

 WE BELIEVE THAT PRIOR TO OUR PUBLIC STATEMENTS REGARDING THE DIRECTION OF THE
       COMPANY, MANAGEMENT AND THE BOARD WERE PURSUING A FLAWED STRATEGY.

      Prior to our  involvement  in Lamson,  the Company was pursuing a publicly
disclosed strategy of pursuing  acquisitions to diversify away from the PVC Pipe
business. In connection with its pursuit of this strategy,  the Company expanded
its  credit  facility  from $125  million to $250  million  and called a special
shareholders  meeting to double  the  authorized  shares of common  stock of the
Company from 20 million shares to 40 million shares.  In our view, it would make
much  more  sense for the  Company  to sell the PVC Pipe  business  and use cash
resources to repurchase its own stock so long as the Company's  shares  continue
to be  undervalued.  We believe  that  Lamson  should not be  pursuing  any such
acquisition  strategy until its shares are trading at multiples similar to those
of its peers,  and only then might it make sense  (and,  in such  circumstances,
only to pursue highly selective acquisitions which would leverage the Carlon and


                                      -6-


Lamson  Home  Products  distribution  channels).  We believe our  nominees  will
represent the Lamson  shareholders'  best interests in helping the Board analyze
potential   acquisitions   should  the  time  come  and  make  sure  the  Lamson
shareholders' interests are represented in those decisions.

       WE BELIEVE CARLON AND LAMSON HOME PRODUCTS ARE EXTREMELY ATTRACTIVE
                                   BUSINESSES.

      We  believe  Lamson has a  terrific  opportunity  to build upon the strong
brand names and  value-added  product  portfolios  of the Carlon and Lamson Home
Products  businesses.   Those  opportunities   deserve  the  full  attention  of
management and the Lamson Board.

      o  Over the past  several  years,  the  Carlon and  Lamson  Home  Products
         businesses,   which  together  represented  approximately  67%  of  the
         Company's  revenue  in 2006,  have  shown  consistent  improvements  in
         revenue and operating  income driven by strong end market  demand,  the
         ability to pass through raw material price increases to customers,  and
         significant process improvements  including  manufacturing  automation,
         inventory management, and distribution efficiencies.

      o  Carlon's  revenue has grown by  approximately  39% from $188 million in
         2001 to $261 million in 2006,  and  operating  margin has improved from
         7.8% in 2001 to 14.6% in 2006. THIS REPRESENTS A 6.8% REVENUE  COMPOUND
         ANNUAL  GROWTH  RATE  ("CAGR")  AND A 680 BASIS  POINT  IMPROVEMENT  IN
         OPERATING MARGIN.

      o  Lamson Home Products  revenue has grown by  approximately  82% from $62
         million  in 2001 to $113  million  in 2006,  and  operating  margin has
         improved  from 6.0% in 2001 to 13.8% in 2006.  THIS  REPRESENTS A 12.8%
         REVENUE CAGR AND A 780 BASIS POINT IMPROVEMENT IN OPERATING MARGIN.

      Conversely,  we believe despite meaningful  operational  improvements over
the past  several  years  in plant  automation  and  distribution,  the PVC Pipe
business,  which  represented the remaining  approximately  33% of the Company's
revenue in 2006, continues to be extremely volatile based on cyclical end market
demand  and high  correlation  to raw  material  input  costs.  We  believe  the
volatility  associated  with the PVC  Pipe  business  will  continue  to  demand
management's  increased  attention and distract  management from focusing on the
core businesses.

      We believe that in the current market environment, the Company has a prime
opportunity  to sell the PVC Pipe business at attractive  terms.  On January 16,
2007, PW Eagle, Inc., a competitor in the PVC pipe market ("PWEI"),  announced a
definitive  agreement  to be acquired by J-M  Manufacturing  Company,  Inc.  for
$33.50 per share  (the "PWEI  Acquisition").  Based on analyst  estimates,  this
purchase price  represents an Enterprise  Value / Normalized  EBITDA multiple of
between  6.4x  and  7.0x.  The PWEI  Acquisition  further  demonstrates,  in our
opinion,  that the current  market has strong  demand for assets  similar to the
Company's PVC Pipe business. We believe,  therefore,  that the Company currently
has an excellent  opportunity to maximize  shareholder value by divesting itself
of this non-core asset.


                                      -7-


      We are cognizant of the potential structural issues surrounding a sale and
separation of the PVC Pipe business from  Lamson's  other  businesses.  However,
regardless  of any  structural  challenges  or  opportunities,  we  believe  the
Company's  stock price is deeply  discounted  in the market  today and that this
situation can and must be remedied. If management and the Lamson Board determine
after  conducting a thorough  analysis that the PVC Pipe  business  represents a
core piece of the consolidated  Lamson business and should not be separated from
the Carlon and Lamson  Home  Products  businesses,  then we believe  the Company
should explore a value-maximizing event through the sale of the entire Company.

      The Ramius  Nominees  are fully  committed  to our  platform  to  increase
shareholder  value and we believe  their  presence on the Lamson Board will help
assure  that a  process  for the sale of the PVC  Pipe  business  or the  entire
Company is carried forward vigorously.

   WE BELIEVE THE RAMIUS NOMINEES HAVE THE EXPERIENCE NECESSARY TO OVERSEE AN
     EFFORT TO MAXIMIZE SHAREHOLDER VALUE THROUGH STRATEGIC ALTERNATIVES AND
                          CORPORATE GOVERNANCE REFORMS

      The Ramius  Group,  as one of the largest  shareholders  of Lamson,  has a
vested financial  interest in the maximization of the value of your Shares.  Our
interests  are aligned with the interests of all  shareholders.  We believe that
the Ramius Nominees have extensive  experience in private and public investment,
business  management and mergers and acquisitions as further  discussed in their
biographical  extracts below.  For example,  Mr.  Caporale was President,  Chief
Executive  Officer and a director  of AMH  Holdings,  Inc.,  when AMH sold a 50%
equity  interest in AMH to affiliates of  Investcorp  S.A. in December  2004. In
addition,  Mr.  Fox was  Co-Chairman  of the Board of  Loehmanns  Holdings,  Inc
(Nasdaq:LHMS)  from 2000 until  Loehmanns  was sold to a private  equity fund in
October 2004. Mr. Fox served as Chairman of the Special Committee overseeing the
sale process and supervised the negotiations of the  transaction.  If elected to
the Lamson Board,  the Ramius  Nominees  will  endeavor to use their  collective
experience to oversee the Company with a goal of implementing  the strategic and
operational  changes  espoused by the Ramius  Group as well as  exploring  other
alternatives to maximize shareholder value. There can be no assurance that these
goals will be achieved if the Ramius Nominees are elected.

      The Ramius Nominees,  if elected,  will represent a minority of the Lamson
Board. If elected,  the Ramius Nominees will,  subject to their fiduciary duties
as  directors,  work with the other  members of the  Lamson  Board to take those
steps that they deem are necessary to facilitate the  consummation  of a sale of
the PVC Pipe business or the entire Company in a competitive sales process.  The
Ramius  Nominees,  if elected,  would also lobby the Lamson  Board to redeem the
Company's "poison pill" shareholders' rights plan and remove other anti-takeover
devices, as described below, in order to allow Lamson shareholders to decide for
themselves  whether they want to accept any  third-party  acquisition  proposal.
Although the Ramius Nominees will not be able to adopt any measures  without the
support of at least some members of the current  Lamson  Board,  we believe that
the  election of the Ramius  Nominees  will send a strong  message to the Lamson
Board that immediate action must be taken to maximize shareholder value.


                                      -8-


 WE BELIEVE LAMSON SHOULD REDEEM ITS POISON PILL AND SHOULD ELIMINATE FROM ITS
     ARTICLES OF INCORPORATION AND CODE OF REGULATIONS CERTAIN ANTI-TAKEOVER
                                   PROVISIONS

      In 1998, the Lamson Board adopted,  without shareholder approval, a rights
plan  or  "poison  pill"  purportedly  to  protect  the  interests  of  Lamson's
shareholders  in the event of a  potential  takeover in a manner or on terms not
approved  by the  Lamson  Board  as  being in the  best  interests  of  Lamson's
shareholders.  We believe  the poison  pill has the  effect of  entrenching  the
Lamson  Board  and  management.   In  our  opinion,   this  lack  of  management
accountability  to  shareholders  adversely  affects  shareholder  value. If the
Ramius  Nominees  are  elected,  they will use their  best  efforts to cause the
Lamson Board to terminate  the poison pill by redeeming  all of the  outstanding
rights. Historically,  proponents of poison pills have asserted that they enable
a board of directors to respond in an orderly  fashion to  unsolicited  takeover
bids by providing  sufficient time to carefully  evaluate the fairness of such a
bid. We oppose  Lamson's  poison pill  because we believe that it places such an
effective obstacle to a takeover bid that it serves to entrench the Lamson Board
and management.  We believe that Lamson's poison pill forces a would-be acquirer
to  negotiate  its bid for Lamson with  management,  instead of making its offer
directly to the shareholders of Lamson. In our opinion,  the power of the Lamson
Board  and  management  to block any bid that  does not  leave  them in  control
adversely affects shareholder value. We further believe that the effect of their
poison pill is to insulate  management from the most fundamental  accountability
to  shareholders  by providing  management and the Lamson Board with a veto over
takeover bids, even when shareholders might favorably view such bids.

      If elected, the Ramius Nominees would also attempt to work with the Lamson
Board to take other  measures to improve  the  Company's  corporate  governance,
including declassifying the Lamson Board. A classified board of directors limits
the  ability of  shareholders  to elect all  directors  on an annual  basis.  We
believe  that  the  annual  election  of  directors  is the  primary  means  for
shareholders to influence  corporate  governance policies and to hold management
accountable for its implementation of those policies.  We view classified boards
as having  the  effect of  insulating  directors  from  being  accountable  to a
corporation's shareholders.

      In  addition  to  the  classified   board,   the  Company's   Articles  of
Incorporation and Code of Regulations contain numerous anti-takeover  provisions
that we believe infringe on the  shareholders'  rights to determine what is best
for the Company and serve to entrench current  management.  These  anti-takeover
provisions include, but are not limited to, the following:

         o  Special   meetings  of  shareholders  may  only  be  called  by  the
            shareholders to the extent they hold 50% of the  outstanding  voting
            shares;

         o  Directors may only be removed by the shareholders for cause and only
            by a vote of at least 80% of the outstanding voting shares;

         o  Certain business  combinations with shareholders who hold 5% or more
            of the  outstanding  voting shares  require the approval of at least
            80% of the outstanding voting shares; and

         o  The  anti-takeover  provisions  above,  as  well  as  certain  other
            provisions,  may be amended or repealed by the shareholders  only by
            the  affirmative  vote of at  least  80% of the  outstanding  voting
            shares.


                                      -9-


      We  believe  the   foregoing   anti-takeover   provisions   disenfranchise
shareholders and have the effect of insulating  directors from being accountable
to the  shareholders.  If elected,  the Ramius  Nominees will,  subject to their
fiduciary   duties,   lobby  the  Lamson  Board  to  eliminate   the   Company's
anti-takeover provisions.


                                      -10-

      There can be no assurance that the actions the Ramius  Nominees  intend to
take as  described  above will be  implemented  if they are  elected or that the
election of the Ramius Nominees will improve the Company's business or otherwise
enhance  shareholder  value.  Your vote to elect the  Ramius  Nominees  does not
constitute a vote in favor of our value enhancing plans for Lamson. Your vote to
elect the Ramius Nominees will,  assuming  sufficient votes are cast in favor of
the Ramius Nominees, have the legal effect of replacing four incumbent directors
of Lamson with the Ramius  Nominees.  There can be no assurance that shareholder
value will be maximized as a result of this  solicitation or the election of the
Ramius Nominees.

      Admiral  Advisors,  an affiliate of Ramius Capital,  and two of the Ramius
Nominees,  Messrs.  Caporale  and Fox,  have entered  into  compensation  letter
agreements (the "Compensation Letter Agreements")  regarding  compensation to be
paid to such Ramius  Nominees  for their  agreement  to be named and to serve as
Ramius  Nominees  and for their  services as  directors  of Lamson,  if elected.
Pursuant to the terms of the Compensation  Letter Agreements,  each nominee will
receive  $5,000 in cash from Admiral  Advisors as a result of the  submission by
Starboard of its  nomination  of the Ramius  Nominees.  Upon the Ramius  Group's
filing of a definitive  proxy  statement with the SEC relating to a solicitation
of  proxies in favor of each  nominee's  election  as a  director  at the Annual
Meeting,  Admiral  Advisors has agreed to allow each nominee to receive a profit


                                      -13-


participation  with  respect  to the  sale  by  Admiral  Advisors  or one of its
affiliates  of the last  $20,000  worth of Shares (the  "Participation  Shares")
beneficially owned by Admiral Advisors or one of its affiliates 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 date of the definitive proxy filing.  Each nominee
will receive a cash payment  equal to the amount,  if any, by which the proceeds
received by Admiral Advisors from the sale of the  Participation  Shares exceeds
$20,000 in the aggregate.

      Starboard and certain  other  affiliates  of Ramius  Capital,  have signed
letter agreements  pursuant to which they agree to indemnify the Ramius Nominees
against  claims  arising  from  the   solicitation   of  proxies  from  Lamson's
shareholders in connection with the Annual Meeting and any related transactions.
Other than as stated herein, there are no arrangements or understandings between
members of the Ramius  Group and any of the Ramius  Nominees or any other person
or persons  pursuant to which the  nomination of the Ramius  Nominees  described
herein is to be made,  other than the consent by each of the Ramius  Nominees to
be named in this Proxy Statement and to serve as a director of Lamson if elected
as such at the Annual  Meeting.  None of the Ramius Nominees are a party adverse
to Lamson or any of its  subsidiaries  or has a  material  interest  adverse  to
Lamson or any of its subsidiaries in any material pending legal proceedings.

      The Ramius Group does not expect that the Ramius  Nominees  will be unable
to stand for  election,  but, in the event that such persons are unable to serve
or for good cause will not serve,  the Shares  represented by the enclosed WHITE
proxy  card  will be voted  for  substitute  nominees.  In  addition,  Starboard
reserves the right to nominate  substitute  persons if Lamson makes or announces
any changes to its Articles of  Incorporation or Code of Regulations or takes or
announces any other action that has, or if consummated would have, the effect of
disqualifying the Ramius Nominees.  In any such case, Shares  represented by the
enclosed WHITE proxy card will be voted for such substitute nominees.  Starboard
reserves the right to nominate additional persons,  and to use the discretionary
authority  granted by the proxies it is soliciting  to vote for such  additional
nominees,  if Lamson  increases  the size of the Lamson Board above its existing
size or  increases  the number of  directors  whose  terms  expire at the Annual
Meeting.  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  in  violation  of the Lamson  Board's  fiduciary
duties.

YOU ARE URGED TO VOTE FOR THE  ELECTION OF THE RAMIUS  NOMINEES ON THE  ENCLOSED
WHITE PROXY CARD.


                                      -14-


VOTING AND PROXY PROCEDURES

      Only  shareholders of record on the Record Date will be entitled to notice
of and to vote at the Annual  Meeting.  Shareholders  who sell Shares before the
Record Date (or acquire  them without  voting  rights after the Record Date) may
not vote such  Shares.  Shareholders  of record on the Record  Date will  retain
their voting rights in connection with the Annual Meeting even if they sell such
Shares  after the Record  Date.  Based on publicly  available  information,  the
Ramius Group  believes that the only  outstanding  class of securities of Lamson
entitled to vote at the Annual Meeting is the Shares.

      We are asking you to give us  discretionary  authority  to  cumulate  your
votes to elect the Ramius  Nominees.  The enclosed  WHITE proxy card may only be
voted for the Ramius  Nominees and does not confer  voting power with respect to
the Company's nominees.  Accordingly,  you will not have the opportunity to vote
for any of Lamson's nominees. You can only vote for Lamson's nominees by signing
and returning a proxy card provided by Lamson.  Shareholders should refer to the
Company's proxy statement for the names,  backgrounds,  qualifications and other
information   concerning  the  Company's  nominees.  The  participants  in  this
solicitation  intend to vote all of their Shares in favor of all or a portion of
the Ramius  Nominees  and will not vote their Shares in favor of any of Lamson's
nominees.

QUORUM

      In order to conduct the election of directors at the Annual  Meeting,  the
holders of Shares entitling them to exercise  seventy-five  percent (75%) of the
voting power of the Company,  present in person or by proxy,  shall constitute a
quorum All Shares that are voted "FOR",  "AGAINST" or "WITHHOLD"  will count for
purposes of  establishing  such quorum and will be treated as Shares entitled to
vote at the Annual Meeting.

CUMULATIVE VOTING FOR ELECTION OF DIRECTORS

      In  accordance  with the  cumulative  voting  rights  set forth in Section
1701.55(C) of the Ohio General Corporation Law, to which the Company is subject,
you are  entitled  to give a nominee  as many votes as is equal to the number of
shares you own  multiplied by the number of directors to be elected,  or you may
distribute your votes among the nominees as you see fit. For example, if you own
100 shares as of the Record Date, and if four directors are to be elected at the
Annual  Meeting,  you have 400 votes that you can allocate among the nominees in
any  manner  you  choose.  If four  directors  are to be  elected  at the Annual
Meeting,  the four nominees receiving the highest number of affirmative votes at
the Annual Meeting will be elected to the Lamson Board.

      Under Ohio law, the exercise of cumulative  voting  rights is  conditioned
upon the  giving of  written  notice  that  cumulative  voting is desired to the
President, a Vice President or the Secretary of the Company at least forty-eight
hours before the Annual Meeting. We intend to give such written notice to invoke
our right to cumulate our votes for the election of the Ramius Nominees.

      Shares represented by a valid, unrevoked WHITE proxy card will be voted in
accordance  with the  recommendations  made in this Proxy  Statement  unless you
otherwise  indicate  on the proxy  card.  We are  soliciting  the  discretionary


                                      -15-


authority to cumulate  votes,  and the persons  named as proxies on the enclosed
WHITE proxy card will have the authority to cumulate  votes at their  discretion
at the Annual Meeting.  We will use the authority  granted to us by the enclosed
WHITE proxy card to cumulate votes at our discretion for all or a portion of the
Ramius  Nominees in order to assure that the maximum  number of Ramius  Nominees
are elected to the Lamson Board.

      A shareholder  may cast votes for the Ramius Nominees either by so marking
the ballot at the Annual Meeting or by specific voting  instructions sent with a
signed proxy to either the Ramius Group in care of MacKenzie  Partners,  Inc. at
the address set forth on the back cover of this Proxy  Statement or to Lamson at
25701 Science Park Drive, Cleveland, Ohio 44122 or any other address provided by
Lamson.

WITHHELD VOTES

      A vote to  "WITHHOLD"  for any  nominee for  director  will be counted for
purposes  of  determining  whether a quorum is  present,  but will have no other
effect on the outcome of the vote on the election of directors.

DISCRETIONARY VOTING

      Shares  held in  "street  name" and held of record  by banks,  brokers  or
nominees  may not be  voted  by such  banks,  brokers  or  nominees  unless  the
beneficial owners of such Shares provide them with instructions on how to vote.

REVOCATION OF PROXIES

      Shareholders  of Lamson  may  revoke  their  proxies  at any time prior to
exercise  by  attending  the  Annual  Meeting  and  voting in  person  (although
attendance at the Annual Meeting will not in and of itself constitute revocation
of a proxy) or by delivering a written notice of  revocation.  The delivery of a
subsequently   dated  proxy  which  is  properly  completed  will  constitute  a
revocation of any earlier proxy.  The revocation may be delivered  either to the
Ramius Group in care of MacKenzie Partners, Inc. at the address set forth on the
back cover of this Proxy  Statement  or to Lamson at 25701  Science  Park Drive,
Cleveland,  Ohio  44122 or any other  address  provided  by  Lamson.  Although a
revocation is effective if delivered to Lamson,  the Ramius Group  requests that
either the original or  photostatic  copies of all  revocations be mailed to the
Ramius Group in care of MacKenzie Partners, Inc. at the address set forth on the
back  cover  of this  Proxy  Statement  so that  Starboard  will be aware of all
revocations  and can more  accurately  determine  if and when  proxies have been
received  from the  holders  of  record  on the  Record  Date and the  number of
outstanding Shares represented thereby.  Additionally,  MacKenzie Partners, Inc.
may use this information to contact  shareholders who have revoked their proxies
in order to solicit later dated proxies for the election of the Ramius Nominees.

IF YOU WISH TO VOTE FOR THE ELECTION OF THE RAMIUS NOMINEES TO THE LAMSON BOARD,
PLEASE  SIGN,  DATE AND RETURN  PROMPTLY  THE  ENCLOSED  WHITE PROXY CARD IN THE
POSTAGE-PAID ENVELOPE PROVIDED.
