LMS Lamson Sessions

Admiral Advisors, LLC, a subsidiary of Ramius Capital Group, L.L.C. (collectively, �Ramius�) today delivered a letter to the President and Chief Executive Officer of The Lamson & Sessions Co. (�Lamson�)(NYSE: LMS) and its Board of Directors in which it urged Lamson to promptly set a date for its 2007 annual meeting of shareholders or add two Ramius representatives to Lamson�s Board of Directors. In addition, Starboard Value and Opportunity Master Fund Ltd., an affiliate of Ramius, today filed preliminary proxy materials with the Securities and Exchange Commission seeking to elect its nominees to the Board of Directors of Lamson at the 2007 annual shareholders� meeting. Full text of the letter follows: 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, Jeffrey C.
