On December 3, 2012, the Board of Directors ("Board") of Cliffs Natural Resources Inc. (the "Company") elected Timothy W. Sullivan to the Board effective as of January 14, 2013. The Board has determined that Mr. Sullivan has no material relationship with the Company (directly or as a partner, shareholder or officer of an organization that has a relationship with the Company) and is independent within the Company's director independence standards, which are consistent with the New York Stock Exchange's director independence standards as currently in effect. Effective July 1, 2013, Mr. Sullivan will become a member of the Audit Committee.

As a non-employee director, Mr. Sullivan will receive compensation in the same manner as the Company's other non-employee directors, which compensation the Company previously disclosed in its definitive proxy statement on Schedule 14A as filed with the Securities and Exchange Commission on March 23, 2012 (the "2012 Proxy Statement"). Mr. Sullivan will participate in the Company's Nonemployee Directors' Compensation Plan (Amended and Restated as of December 31, 2008) (the "Plan"), a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference. The Plan provides, among other things, for an annual equity grant to non-employee directors. The Plan also provides, among other things, for the opportunities for non-employee directors, in certain circumstances, to receive a portion of their annual retainer fee in common shares, par value $0.125 per share, of the Company (the "Shares"), to invest additional amounts of their compensation payable for services as a non-employee director in Shares and to defer all or a portion of their compensation payable as a non-employee director. Pursuant to the Plan, Mr. Sullivan is to receive a prorated annual equity grant of restricted shares in an amount to be calculated as of January 14, 2013.

The Company also expects to enter into Indemnification Agreements with Mr. Sullivan, the form of which is included as Exhibit 10.2 to this Current Report on Form 8-K and is incorporated herein by reference. The Indemnification Agreement provides that, to the extent permitted by Ohio law, the Company will indemnify Mr. Sullivan against all expenses, costs, liabilities and losses (including attorneys' fees, judgments, fines or settlements) incurred or suffered by him in connection with any suit in which he is a party or otherwise involved as a result of his service as a member of the Board. The foregoing discussion of the terms of the form of Indemnification Agreement is qualified in its entirety by reference to the full text of the Indemnification Agreement.

A copy of the press release relating to the appointment of Mr. Sullivan is attached here to as Exhibit 99.1
