CERTAIN TERMS OF RESTRICTED SHARES

     1. Signing of and Compliance With Agreement. Grantee shall not have any right with respect to the Restricted Shares issued pursuant to this Agreement, unless and until Grantee has

COPIES OF SUCH PLAN AND AGREEMENT ARE ON FILE IN THE OFFICES OF THE LAMSON & SESSIONS CO., CLEVELAND, OHIO AND WILL BE MAILED TO THE REGISTERED OWNER, WITHOUT CHARGE, WITHIN FIVE DAYS AFTER RECEIPT OF WRITTEN REQUEST THEREFOR.

     3. Certificates in Company Custody. Stock certificates evidencing Restricted Shares shall be held in custody by the Company until the restrictions thereon shall have lapsed, and as a condition of any Restricted Shares, the Grantee shall have delivered a stock power relating to the Restricted Shares.

     4. Restriction Period. Subject to the provisions of the 1998 Plan and this Agreement, during the period from the Date of Grant until                                          (the “Restriction Period”), the Grantee shall not be permitted to sell, transfer, pledge, assign or otherwise encumber the Restricted Shares awarded under the 1998 Plan, except that the Grantee’s rights with respect to such Restricted Shares may be transferred by will or pursuant to the laws of descent or distribution.

     5. Acceleration of Restricted Shares. Notwithstanding Section 4 of this Article II, if the Grantee is no longer serving on the Company’s Board due to death, disability or a Change in Control, the Grantee is immediately entitled to receive the Restricted Shares.

     6. Shareholder Rights. The Grantee shall have, with respect to the Restricted Shares covered by this Agreement, all of the rights of a shareholder of the Company, including the right

to vote the shares, and the right to receive any dividends paid thereon, provided that such shares, together with any additional shares which the Grantee may become entitled to receive by virtue of a share dividend, a merger or reorganization in which the Company is the surviving corporation or any other change in capital structure, except as otherwise required by Section 5 of this Article II, shall be subject to the restrictions herein set forth.

     7. Forfeiture. Upon termination of the Grantee from the Company’s Board during the Restriction Period for any reason other than death, disability or a Change in Control, all Restricted Shares still subject to restriction shall be forfeited by the Grantee.

ARTICLE III

GENERAL PROVISIONS

     1. Compliance with Law. Notwithstanding any other provision of this Agreement, the Company may not issue any of the Restricted Shares if such issuance would result in a violation of law.

     2. Adjustments. The Board may (a) make any adjustments in the number or kind of Restricted Shares or other securities covered by this Agreement that the Committee determines in good faith to be equitably required, or (b) provide alternative consideration to the Grantee in substitution of any or all of the Grantee’s rights under this Agreement, in order to prevent any dilution or expansion of the Grantee’s rights under this Agreement that otherwise would result from any (i) stock dividend, stock split, combination of shares, recapitalization or other change in the capital structure of the Company, (ii) merger, consolidation, spin-off, spin-out, split-off, split-up, reorganization, partial or complete liquidation of the Company or other distribution of assets, issuance of rights or warrants to purchase securities of the Company or (iii) other transaction or event having an effect similar to any of the foregoing.

     3. Relation to Other Benefits. The Company will not take into account any economic or other benefit to the Grantee under this Agreement or the 1998 Plan in determining any benefits to which the Grantee may be entitled under any retirement or other benefit or compensation plan maintained by the Company or a Subsidiary. The Company will not reduce the amount of any life insurance coverage available to any beneficiary under any life insurance plan covering directors of the Company or a Subsidiary as a result of any economic or other benefit to the Grantee under this Agreement or the 1998 Plan.

     4. Amendments. Any amendment to the 1998 Plan will be deemed to be an amendment to this Agreement to the extent that the 1998 Plan amendment (a) is applicable to awards of Restricted Shares and (b) does not adversely affect the rights of the Grantee with respect to the Restricted Shares. In order for a 1998 Plan amendment that adversely affects the Restricted Shares to be effective against the Grantee, the Grantee must consent to such 1998 Plan amendment.

     5. Severability. If any provision of this Agreement is invalidated for any reason by a court of competent jurisdiction, the invalid provision will be deemed to be separable from the other provisions of this Agreement and the remaining provisions will continue to be valid and fully enforceable.

     6. Counterparts. This Agreement may be executed in one or more counterparts, each of which is an original but all of which together constitute one and the same document.

     7. Governing Law. This Agreement is made under, and will be construed in accordance with, the laws of the State of Ohio, without giving effect to its principles of conflict of laws.
