 Item 5.   Other Events

 AMENDMENT OF RIGHTS AGREEMENT

           On September 22, 1999, the Board of Directors of the Company
 approved an amendment (the "Amendment") to the Rights Agreement, as amended
 and restated as of December 10, 1998, between the Company and Harris Trust
 and Savings Bank, as Rights Agent (the "Rights Agreement").  The Amendment,
 among other things, reduces the threshold beneficial ownership level of
 common stock which triggers the distribution and exercisability of the
 rights issued pursuant to the Rights Agreement (the "Rights") from 20% to
 10%.  As amended, if a person, together with such person's affiliates and
 associates, becomes the beneficial owner of 10% or more of the outstanding
 common stock of Ryerson Tull, the outstanding Rights (other than those held
 by the acquiror) become exercisable for common stock of Ryerson Tull having
 a value of two times the exercise price of the Right.  Any person that
 beneficially owns 10% or more of the outstanding shares of Ryerson Tull
 common stock on September 22, 1999 and has publicly disclosed such
 ownership prior to such date will not trigger the Rights unless such person
 subsequently acquires additional shares resulting in its beneficial
 ownership of 15% or more of the outstanding shares of Ryerson Tull common
 stock.  The Amendment also contains certain other changes relating to the
 reduction of the triggering threshold to 10%.

           The Amendment also provides that during the six month period
 following a change of control of the Board of Directors of the Company
 (resulting in a majority of the Board of Directors being comprised of
 persons who were not nominated by the Board of Directors in office
 immediately prior to such election) that occurs within nine months after an
 unsolicited third party acquisition or business combination proposal, then
 the Rights will only be redeemable by the Board of Directors either (1) if
 they have followed certain prescribed procedures or (2) in any other case,
 provided that, if in any such other case their decision regarding
 redemption and any acquisition or business combination is challenged as a
 breach of fiduciary duty of care or loyalty, the directors can establish
 the entire fairness of such decision without the benefit of any business
 judgment rule or other presumption.


 AMENDMENT OF BY-LAWS

           On September 22, 1999, the Board of Directors of the Company also
 approved an amendment to its By-Laws (the "By-Law Amendment") to change the
 advance notice period required for shareholder proposals and nominations
 for election of directors from not less than 90 days nor more than 115 days
 prior to an annual meeting to not less than 90 days nor more than 120 days
 prior to the mailing date of the proxy statement for the prior year's
 annual meeting.  Under the amended By-Laws, to be properly brought before
 the next annual meeting of shareholders of the Company, shareholder
 proposals and nominations for election of directors must be received by the
 Secretary no earlier than November 18, 1999 and no later than December 18,
 1999.

           The foregoing descriptions of the Amendment and the By-Law
 Amendment do not purport to be complete and are qualified in their entirety
 by reference to the amended and restated Rights Agreement and the amended
 and restated By-Laws, respectively, which are exhibits hereto and
 incorporated herein by reference.
