On June 17, 2008, A. M. Castle & Co., Inc. (the "Company") announced that it has appointed Mr. Scott F.

Boik, who has served the Company in the role of Vice President-Finance and Chief Financial Officer since October 2004. Mr. Boik will serve as Chief Financial Officer through June 30, 2008 and will remain with the Company through July, 2008 in order to assist the Company and to ensure a smooth transition of responsibility.

Since 2006, Mr. Stephens has served as Chief Financial Officer at Lawson Products, Inc., a $500 million distributor and marketer of systems, services and products to the industrial, commercial and institutional maintenance, repair and operations marketplace. From 2004 to 2006, Mr. Stephens served as Senior Vice President Finance and Accounting at Lawson Products. Prior thereto, from 2000 to 2004, Mr. Stephens served as Chief Financial Officer of Wormser Company.

The Company has agreed to pay Mr. Stephens a base salary of $310,000 per year. Mr. Stephens will participate in the Company’s short-term incentive plan (“STIP”), with a target bonus for 2008 of 60% of annual base salary and a maximum bonus for 2008 of 120% of annual base salary. For 2008, Mr. Stephens will receive a guaranteed payment under the Company’s STIP equal to the target bonus prorated for the number of months employed at the Company (or $93,000). Mr. Stephens will participate in the Company’s long-term incentive plan (“LTIP”), with a target LTIP payout of common stock for 2008-2010 performance period of 80% of annual base salary and a maximum LTIP payout for 2008-2010 or 160% of annual base salary. For the 2008-2010 LTIP, Mr. Stephens will receive 9,400 shares of common stock at target and 18,800 shares of common stock at maximum, prorated for the number of months employed at the Company.

As additional compensation for the loss of a portion of Mr. Stephen’s long term incentive award from his prior employer, subject to approval by the Human Resources Committee of the Board of Directors and the Company’s Board of Directors, Mr. Stephens will receive an award of $200,000 in restricted stock which would vest upon the completion of 18 months of service with the Company.
