Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 5(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Includes 2,075 unvested restricted stock units subject to service criteria.
(2) Each share of phantom stock is the economic equivalent of one share of the Issuer's common stock. In connection with the acquisition by the Issuer of Earle M. Jorgensen Company ("EMJ") in April 2006, the Issuer assumed the obligation resulting from EMJ's settlement with the U.S. Department of Labor to contribute shares of the Issuer's common stock to the Earle M. Jorgensen Company Supplemental Stock Bonus Plan, a phantom stock bonus plan. As a former employee of EMJ, Mr. Durham is entitled to receive 657.75 phantom shares of the Issuer's common stock under the Earle M. Jorgensen Company Supplemental Stock Bonus Plan. This obligation will be satisfied by a cash payment to Mr. Durham upon the termination of his employment with the Issuer.
