         The following documents filed by Ryerson Tull, Inc., a Delaware

amended, and the Securities Exchange Act of 1934, as amended (the "Exchange

         (b)      Quarterly Report on Form 10-Q of the Company for the quarter
                  ended March 31, 2002;

                  Statement filed on Form S-3 on September 25, 1995, including
                  any amendment or report filed with the Commission for the

         (d)      the description of the Company's Series D Junior Participating
                  Preferred Stock included in the Company's amended Registration
                  Statement filed on Form 8-A/A-2 on October 6, 1999, including
                  any amendment or report filed with the Commission for the
                  purpose of updating such description.

         All documents subsequently filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment which indicates that all securities offered have been
sold or which deregisters all securities then remaining unsold, shall be deemed
to be incorporated herein by reference and shall be deemed a part hereof from
the date of filing of such documents.

Item 4.  Description of Securities.

         Not applicable.

Item 5.  Interests of Named Experts and Counsel.

         The legality of the shares of common stock offered hereby has been
passed upon by Joyce E. Mims, Vice President and General Counsel of the Company.
As of May 10, 2002, Ms. Mims had options to acquire 58,500 shares of Company

Item 6.  Indemnification of Directors and Officers.

         (a) The General Corporation Law of Delaware (Section 145) gives
Delaware corporations broad powers to indemnify their present and former
directors and officers and those of affiliated corporations against expenses
incurred in the defense of any lawsuit to which they are made parties by reason
of being or having been such directors or officers, subject to specified
conditions and exclusions; gives a director or officer who successfully defends
an action the right to be so indemnified; and authorizes the Company to buy
directors' and officers' liability insurance. Such indemnification is not
exclusive of any of the rights to which those indemnified may be entitled under
any by-laws, agreement, vote of stockholders or otherwise.

         (b) Article Eight of the Certificate of Incorporation of the Company
permits, and Article VI of the By-Laws of the Company provides for,
indemnification of directors, officers, employees and agents to the full extent
permitted by law.

                                       2

<PAGE>

         (c) The Corporation maintains directors' and officers' liability
insurance coverage for its directors and officers and those of its subsidiaries
and for certain other executive employees. This coverage insures such persons
against certain losses that may be incurred by them in their respective
capacities as directors, officers or employees, with respect to which they may
or may not be indemnified under the provisions of the Certificate of
Incorporation or By-Laws of the Corporation or otherwise.

Item 7.  Exemption from Registration Claimed.

         Not Applicable.

Item 8.  Exhibits.

         See Exhibit Index which is incorporated herein by reference.

Item 9.  Undertakings.

         The undersigned registrant hereby undertakes:

         (1)      To file, during any period in which offers or sales are being
                  made, a post-effective amendment to this registration
                  statement:

                  (i)      To include any prospectus required by Section
                           10(a)(3) of the Securities Act of 1933;

                  (ii)     To reflect in the prospectus any facts or events
                           arising after the effective date of the registration
                           statement (or the most recent post-effective
                           amendment thereof) which, individually or in the
                           aggregate, represent a fundamental change in the
                           information set forth in the registration statement.
                           Notwithstanding the foregoing, any increase or
                           decrease in volume of securities offered (if the
                           total dollar value of securities offered would not
                           exceed that which was registered) and any deviation
                           from the low or high end of the estimated maximum
                           offering range may be reflected in the form of
                           prospectus filed with the Commission pursuant to Rule
                           424(b) if, in the aggregate, the changes in volume
                           and price represent no more than a 20 percent change
                           in the maximum aggregate offering price set forth in
                           the "Calculation of Registration Fee" table in the
                           effective registration statement;

                  (iii)    To include any material information with respect to
                           the plan of distribution not previously disclosed in
                           the registration statement or any material change to
                           such information in the registration statement;

                  provided, however, that paragraphs (1)(i) and (1)(ii) do not
                  apply if the registration statement is on Form S-3 or Form S-8
                  or Form F-3, and the information required to be included in a
                  post-effective amendment by those paragraphs is contained in
                  periodic reports filed with or furnished to the Commission by
                  the registrant pursuant to Section 13 or 15(d) of the
                  Securities Exchange Act of 1934 that are incorporated by
                  reference in the registration statement.

         (2)      That, for the purpose of determining any liability under the
                  Securities Act of 1933, each such post-effective amendment
                  shall be deemed to be a new registration statement relating to
                  the securities offered therein, and the offering of such
                  securities at that time shall be deemed to be the initial bona
                  fide offering thereof.

         (3)      To remove from registration by means of a post-effective
                  amendment any of the securities being registered which remain
                  unsold at the termination of the offering.

                                       3

<PAGE>

         The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the provisions referred to under Item 6, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

Item 6.  Indemnification of Directors and Officers.

         (a) The General Corporation Law of Delaware (Section 145) gives
Delaware corporations broad powers to indemnify their present and former
directors and officers and those of affiliated corporations against expenses
incurred in the defense of any lawsuit to which they are made parties by reason
of being or having been such directors or officers, subject to specified
conditions and exclusions; gives a director or officer who successfully defends
an action the right to be so indemnified; and authorizes the Company to buy
directors' and officers' liability insurance. Such indemnification is not
exclusive of any of the rights to which those indemnified may be entitled under
any by-laws, agreement, vote of stockholders or otherwise.

         (b) Article Eight of the Certificate of Incorporation of the Company
permits, and Article VI of the By-Laws of the Company provides for,
indemnification of directors, officers, employees and agents to the full extent
permitted by law.

                                       2
(c) The Corporation maintains directors' and officers' liability
insurance coverage for its directors and officers and those of its subsidiaries
and for certain other executive employees. This coverage insures such persons
against certain losses that may be incurred by them in their respective
capacities as directors, officers or employees, with respect to which they may
or may not be indemnified under the provisions of the Certificate of
Incorporation or By-Laws of the Corporation or otherwise.

Item 7.  Exemption from Registration Claimed.

Item 8.  Exhibits.

         See Exhibit Index which is incorporated herein by reference.

Item 9.  Undertakings.

         The undersigned registrant hereby undertakes:

         (1)      To file, during any period in which offers or sales are being
                  made, a post-effective amendment to this registration
                  statement:

                  (i)      To include any prospectus required by Section
                           10(a)(3) of the Securities Act of 1933;

                  (ii)     To reflect in the prospectus any facts or events
                           arising after the effective date of the registration
                           statement (or the most recent post-effective
                           amendment thereof) which, individually or in the
                           aggregate, represent a fundamental change in the
                           information set forth in the registration statement.
                           Notwithstanding the foregoing, any increase or
                           decrease in volume of securities offered (if the
                           total dollar value of securities offered would not
                           exceed that which was registered) and any deviation
                           from the low or high end of the estimated maximum
                           offering range may be reflected in the form of
                           prospectus filed with the Commission pursuant to Rule
                           424(b) if, in the aggregate, the changes in volume
                           and price represent no more than a 20 percent change
                           in the maximum aggregate offering price set forth in
                           the "Calculation of Registration Fee" table in the
                           effective registration statement;

                  (iii)    To include any material information with respect to
                           the plan of distribution not previously disclosed in
                           the registration statement or any material change to
                           such information in the registration statement;

                  provided, however, that paragraphs (1)(i) and (1)(ii) do not
                  apply if the registration statement is on Form S-3 or Form S-8
                  or Form F-3, and the information required to be included in a
                  post-effective amendment by those paragraphs is contained in
                  periodic reports filed with or furnished to the Commission by
                  the registrant pursuant to Section 13 or 15(d) of the
                  Securities Exchange Act of 1934 that are incorporated by
                  reference in the registration statement.

         (2)      That, for the purpose of determining any liability under the
                  Securities Act of 1933, each such post-effective amendment
                  shall be deemed to be a new registration statement relating to
                  the securities offered therein, and the offering of such
                  securities at that time shall be deemed to be the initial bona
                  fide offering thereof.

         (3)      To remove from registration by means of a post-effective
                  amendment any of the securities being registered which remain
                  unsold at the termination of the offering.

                                       3
The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the provisions referred to under Item 6, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.
