), today sent a letter to the Cliffs Board of Directors urging it to hold the Company's annual meeting of shareholders on or before June 4, 2014. Should the Company fail to set a prompt date for the annual meeting, Casablanca intends to commence a consent solicitation to call a Special Meeting of shareholders for the election of the Company's Board of Directors. “More than a month has passed since we met in person with Cliffs and agreed to a framework for a settlement that would have brought a fresh perspective and valuable expertise to a Board that has overseen a tremendous destruction of value,” said Donald Drapkin, Chairman of Casablanca. “The members of this Board have not made any meaningful investment in the Company's shares. In fact, Cliffs' Executive Chairman has never invested a dollar of his own money, but continues to stymie investors' legitimate efforts to restore value at the Company, in our view. We believe the pitifully small steps that the Board has taken to date have only been in response to Casablanca's efforts. This Board must be held accountable.” The letter Casablanca today sent to the Cliffs Board follows: April 21, 2014 Members of Cliffs Natural Resources, Inc. Board of Directors In care of: James F. Kirsch Executive Chairman Cliffs Natural Resources Inc. 200 Public Square, Suite 3300 Cleveland, OH 44114 Members of the Board: We are writing to request that Cliffs hold its annual meeting of shareholders on or before June 4, 2014. Should the Board fail to set a prompt date for the annual meeting, Casablanca intends to commence a consent solicitation to call a Special Meeting of shareholders for the election of the Board of Directors, in accordance with the Company's regulations and consistent with the rights of shareholders under Ohio law. Casablanca has spent over a month working within an agreed-upon framework to reach a settlement that would have provided a meaningful voice for shareholders and accelerated a desperately-needed process to restore value at Cliffs. Although we are bound to keep the details of our discussions private, we can state that Casablanca offered significant concessions as part of an agreement in principle. Despite our good-faith efforts, we have been thwarted by foot-dragging and evasion throughout the process. This has now culminated in the Board's refusal to consummate the agreement or offer any meaningful insight into what settlement terms might bridge our respective concerns. We are frustrated by the Board's apparent stall tactics, and believe that it has failed to show any genuine intention to conclude a mutually-acceptable settlement agreement in the best interests of shareholders. We remain troubled that the Board has delayed the Company's annual election of directors, today confirming to us that it has no intention of holding its annual meeting imminently. We find this management entrenchment tactic unacceptable. Despite the Company's suggestion to the contrary, at no time did Casablanca request a delay of the shareholder meeting.^1 Casablanca believes the Cliffs' Board continues to lack any sense of urgency, and that its stall tactics exemplify the flawed decision-making that has brought Cliffs to where it is today. We believe this demonstrates a lack of leadership and vision for Cliffs, and that shareholders deserve better. Very truly yours, /s/         /s/         /s/   Donald G.

A record date merely establishes the date on which a shareholder must own shares if they are to be eligible to vote in the annual meeting. Cliffs' record date was originally set for March 7, 2014—a deadline that was only four days away when the Company contacted Casablanca on March 3, 2014, and indicated its desire to discuss a settlement. In this highly-preliminary discussion, Casablanca suggested that delaying the impending record date might be a productive way to lay the groundwork for meaningful settlement discussions. Cliffs responded by indefinitely suspending its annual meeting date—stating it was doing so “in order to accommodate this request.” Casablanca only suggested that the record date be pushed back, but did not at any time request that the annual meeting itself be delayed.
