Attn: Corporate Secretary

      Re: NOTICE OF  SHAREHOLDER  NOMINATION  FOR ELECTION OF DIRECTORS  FOR
          THE 2007 ANNUAL MEETING OF  SHAREHOLDERS  OF THE LAMSON & SESSIONS CO.

DEAR SIR:

      This letter is intended to serve as notice to The Lamson & Sessions Co.,
an Ohio corporation ("Lamson" or the "Company"), as to the nomination by
Starboard Value and Opportunity Master Fund Ltd., an exempted company organized
under the laws of the Cayman Islands ("Starboard"), of nominees 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 and all Exhibits attached hereto are collectively referred to
as the "Notice." Starboard is the beneficial owner of 1,194,816 shares of common
stock, no par value per share (the "Common Stock"), of Lamson, 1,000 shares of
which are held of record. Through this Notice, Starboard hereby nominates and
notifies you of its intent to nominate William J. Fox, Lee D. Meyer, Jeffrey C.
Smith and Jeffrey M. Solomon as nominees (the "Nominees") to be elected to the
Lamson Board at the 2007 Annual Meeting. Starboard believes that the terms of
four (4) Class I directors currently serving on the Lamson Board expire 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, Starboard reserves the right to nominate additional nominees to be elected
to the Lamson Board at the 2007 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. If this
Notice shall be deemed for any reason by a court of competent jurisdiction to be
ineffective with respect to the nomination of any of the Nominees nominated by
Starboard at the 2007 Annual Meeting, or if any individual Nominee shall be
unable to serve for any reason, this Notice shall continue to be effective with
respect to the remaining Nominee and as to any replacement Nominee(s) selected
by Starboard.

                          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.

[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,
