                          Pursuant to Section 151(g)
                         of the General Corporation Law
                           of the State of Delaware

United  States  Steel  Corporation, a corporation duly organized  and  existing
under the laws of the State of Delaware (the "Corporation"), in accordance with
the provisions of Section 151(g) of the General Corporation Law of the State of
Delaware (the "DGCL"), hereby certifies as follows:

  1. Pursuant  to Section 151 of the DGCL and the authority granted  in  the
     Corporation's Restated Certificate of Incorporation, as amended, the
     Executive Committee of the Board of Directors of the Corporation, by
     resolution duly adopted, authorized the creation of a series of Preferred
     Stock designated as the 7.00% Series B Mandatory Convertible Preferred
     Shares, without par value (the  "7.00%  Convertible Preferred Shares") and
     established  the  number, designation, relative rights, preferences and
     limitations of such shares.

  2. On February 7, 2003, the Corporation filed a Certificate of Designation
     with respect to the 7.00% Convertible Preferred Shares (the "Certificate
     of Designation") in the Office of the Secretary of State of Delaware.

  3. In accordance with the Certificate of Designation, all of the issued and
     outstanding 7.00% Convertible Preferred Shares were automatically
     converted into common stock of the Corporation on June 15, 2006, and
     therefore no 7.00% Convertible  Preferred Shares are outstanding, and  no
     7.00%  Convertible Preferred Shares will be issued subject to the
     Certificate of Designation.

  4. The  Board  of  Directors of the Corporation has adopted the  following
     resolutions, and such resolutions have not been amended or modified and
     remain in full force and effect as of the date hereof:

          RESOLVED,  that  none  of  the 7.00% Series B  Mandatory  Convertible
          Preferred   Shares,  without  par  value,  (the  "7.00%   Convertible
          Preferred  Shares") are outstanding and none of the 7.00% Convertible
          Preferred  Shares  will  be  issued subject  to  the  Certificate  of
          Designation previously filed with respect to such shares; and

          FURTHER  RESOLVED,  that  any officer of the  Corporation  is  hereby
          authorized  and directed to execute and file with the Office  of  the
          Secretary  of State of Delaware a Certificate of Elimination  setting
          forth  a copy of these resolutions, whereupon all references  to  the
          7.00%  Convertible  Preferred Shares in  the  Corporation's  Restated
          Certificate of Incorporation, as amended, shall be eliminated; and

          FURTHER  RESOLVED,  that the officers of the Corporation  are  hereby
          authorized  and  directed, for and on behalf of the  Corporation,  to
          take any and all actions and to execute, file, deliver and record all
          such  certificates, instruments, agreements and documents as  may  be
          necessary  or advisable in order to carry out the purpose and  intent
          of the foregoing resolutions.

  5. Pursuant to the provisions of Section 151(g) of the DGCL, all matters set
     forth in the Certificate of Designation with respect to the 7.00%
     Convertible Preferred  Shares  are  hereby eliminated from the
     Corporation's  Restated Certificate of Incorporation, as amended, and the
     shares that were designated to such series are hereby returned to the
     status of authorized but unissued shares of the Preferred Stock of the
     Corporation, without designation as to series.

IN  WITNESS WHEREOF, the Corporation has caused this Certificate to be executed
by Craig D. Mallick, its Secretary, this 5th day of December, 2007.
