Item 1. Description of Registrant’s Securities to be Registered.

Reference is hereby made to the Registration Statement filed with the Securities Exchange Commission on Form 8-A, dated April 1, 2004 (the “Amended Form 8-A”), by Ryerson Inc. (the “Company”) relating to the rights distributed to the stockholders of the Company (the “Rights”) in connection with the Rights Agreement (as amended, the “Rights Agreement”), dated as of November 25, 1997 and amended and restated as of April 1, 2004, between the Company and The Bank of New York (the “Rights Agent”). The Amended Form 8-A is incorporated herein by reference. Capitalized terms used but not defined herein shall have the meaning assigned thereto in the Rights Agreement.

On July 24, 2007, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Rhombus Holding Corporation (“Parent”) and Rhombus Merger Corporation (“Sub”), providing for, among other things, the merger of Sub with and into the Company upon the terms and subject to the conditions set forth in the Merger Agreement.

Only July 24, 2007, in connection with the Company’s execution of the Merger Agreement, the Company and the Rights Agent executed an amendment to the Rights Agreement (the “Amendment”).

The Amendment, among other things, provided that (i) neither Parent, Sub nor any of their existing or future affiliates or associates will become an Acquiring Person, (ii) none of a Stock Acquisition Date, a Distribution Date, an event of the type described in Section 11(a)(ii) of the Rights Agreement or an event of the type described in Section 13 of the Rights Agreement shall occur, and (iii) the Rights will not separate from the shares of Common Stock, in each case, solely by reason of the approval or execution of the Merger Agreement or the announcement or consummation of the Merger, the Merger Agreement or the transactions contemplated thereby.

The Amendment also provides that the Rights Agreement shall expire immediately prior to the Effective Time (as defined in the Merger Agreement), if the Rights Agreement has not otherwise terminated. If the Merger Agreement is terminated, the changes to the Rights Agreement pursuant to the Amendment will be of no further force and effect.

The Rights Agreement and the Amendment are filed as exhibits hereto and are incorporated herein by reference. The foregoing description of the Rights Agreement and the Amendment does not purport to be complete and is qualified in its entirety by reference to such exhibits.
