I. SUMMARY OF THE ACTIONS

On June 4, 2014, Plaintiff Robert Black filed a shareholder derivative action captioned Black v. Cliffs Natural Resources Inc., et al., Case No. CV-14-827803 (the “Black Action”), in the Court of Common Pleas of Cuyahoga County, Ohio. The Complaint alleged, among other things, that the Individual Defendants had breached their fiduciary duties in connection with management and oversight of the Bloom Lake mine facility and the handling of the Company’s

2

dividend (including allegedly false and misleading statements on these subjects during 2012 and 2013), and also in connection with pay practices upon the departure of certain executives during that period. A second shareholder derivative action, Asmussen, et al. v. Cliffs Natural Resources Inc., et al., Case No. CV-14-829259 (the “Asmussen Action”), was filed on July 2, 2014, and included allegations similar to those in the Black Action. A third shareholder derivative action, Williams v. Cliffs Natural Resources Inc., et al., Case No. CV-14-829499 (the “Williams Action”), was filed on July 9, 2014, and asserted allegations similar to those in the Black and the Asmussen Actions.

Pursuant to Court orders dated August 11, 2014, and September 12, 2014, the Asmussen Action and the Williams Action were transferred for consolidation with the Black Action. Pursuant to the Parties’ stipulations and subsequent court orders (the “Stipulated Orders”), the Parties agreed to stay the Actions pending disposition of a motion to dismiss in one of the then-pending federal securities law class actions (collectively, the “Securities Actions”): (i) The Department of the Treasury of the State of New Jersey and its Division of Investment, et al. v. Cliffs Natural Resources Inc. et al., No. 1:14-cv-01031, United States District Court for the Northern District of Ohio (Judge Dan Aaron Polster) (the “New Jersey Action”); and (ii) Stuart Rosenberg, et al. v. Cliffs Natural Resources Inc., et al., No. CV-14-828140, Court of Common Pleas of Cuyahoga County, Ohio (Judge Shannon M. Gallagher) (the “Rosenberg Action”).

During the stay of the Actions and in accordance with the Stipulated Orders, the Parties filed several joint status reports with the Court describing the status of the Securities Actions. The Parties continued the stay of the Actions until the Rosenberg Action reached a settlement in principle.

On December 17, 2015, the Court entered an order granting the unopposed motion to lift the stay of the consolidated Actions for the limited purpose of appointing Co-Lead Plaintiffs and Co-Lead Plaintiffs’ selection of counsel. Pursuant to that order, Plaintiffs George Asmussen and Jeff Asmussen were appointed Co-Lead Plaintiffs; The Shuman Law Firm was appointed Lead Counsel for Co-Lead Plaintiffs; and Weisman, Kennedy & Barris Co., L.P.A. was appointed Liaison Counsel for Co-Lead Plaintiffs.

In August 2015, the Parties began a dialogue regarding the possible resolution of the Actions. On August 6, 2015, and December 11, 2015, counsel for Plaintiffs in the Black Action and the Asmussen Action, respectively, sent settlement demands to Defendants’ Counsel. Key components of the demands included a requirement that Cliffs adopt corporate governance reforms and that any amounts that might be paid into a settlement fund for the New Jersey Action be contributed only by non-Company sources such as applicable insurance carriers up to exhaustion of policy limits. The demands took into account Cliffs’ existing governance policies and procedures and were specifically targeted to address and prevent a recurrence of the alleged wrongdoing that is the subject of the Actions, and also to limit the financial impact of the NewJersey Action on the Company.

3

Over the next several months, the two sides exchanged information and, through their counsel, had numerous discussions presenting and arguing their respective positions as well as prospects and terms for a possible settlement. These discussions eventually resulted in the agreement in principle to resolve, discharge, and settle the Actions, including without limitation all claims raised in the Actions, on the terms and conditions set forth in the Stipulation. The lengthy negotiations were conducted in good faith, at arm’s-length and were hard-fought by experienced counsel. During the negotiations, all Parties had a clear view of the strengths and weaknesses of their respective claims and defenses. Entry into the Stipulation is not an admission by any Party as to the merit or lack of merit of any claims or defenses.

During the period of negotiation, the New Jersey Action was settled in principle, with the payment into the settlement fund to be delivered solely by insurance carriers.

As part of the settlement negotiations, Plaintiffs undertook discovery to confirm that the proposed terms of the Settlement are fair, reasonable and adequate. In particular, Cliffs produced to Plaintiffs substantial sets of documents, many of which were board-level confidential materials, which were examined by Plaintiffs’ Counsel.

Plaintiffs, Plaintiffs’ Counsel, Cliffs and its counsel believe that the proposed Settlement is in the best interests of Cliffs and its shareholders.

II. TERMS OF THE SETTLEMENT

The terms and conditions of the proposed Settlement are set forth in the Stipulation. The following is a summary of its terms. The summary should be read in conjunction with, and is qualified in its entirely by reference to, the text of the Stipulation, which has been filed with the Court and is also available for viewing on Cliffs’ website via link at http://ir.cliffsnaturalresources.com and on the website of Plaintiffs’ Lead Counsel at www.shumanlawfirm.com.

As part of the Settlement of the Actions, Cliffs has agreed to adopt and implement corporate certain governance measures (the “Reforms”) substantially as set forth in the Stipulation within ninety days after the Effective Date of the Settlement, to be maintained for a period of not less than three years from the day they are implemented, unless (but only to the extent) otherwise required by law. The Board, acting by a majority of its non-management members, may alter or amend its compliance with any of the Reforms during the three year period, if it concludes that doing so is required by its fiduciary duties, or that continued compliance would conflict with applicable law or amendments to the corporate regulations approved by the shareholders. If such alteration or amendment is made, the Company must, within no more than 30 days after the alteration or amendment becomes effective, advise Lead Plaintiffs’ Counsel thereof in writing, and state the reasons for the alteration or amendment. Plaintiffs, Plaintiffs’ Counsel and Cliffs agree that the Reforms confer a substantial and material benefit on Cliffs and its shareholders, and the Parties acknowledge and agree that the adoption and implementation of the Reforms is the result of the initiation, prosecution, and settlement

4

of the Actions. In addition, the nature of the settlement funding of the New Jersey Action - - exclusively from applicable directors’ and officers’ (“D&O”) policies - - is consistent with Cliffs’ stated position in the settlement negotiations in these Actions that it would make all reasonable, good faith efforts to secure funding by applicable insurance carriers for any such settlement, which in turn had been elicited by Plaintiffs’ demand in these Actions on the funding issue.

The Board, exercising its independent business judgment, believes that the Settlement and the Reforms are in the best interests of Cliffs and its shareholders.

The Reforms are set out in an attachment at the end of this Notice.

III. DISMISSALS AND RELEASES

The Settlement is conditioned, among other things, upon entry of an order by the Court approving the Settlement and dismissing the Actions on the merits with prejudice.

1.The Stipulation provides that, as of the date when the Court has entered the Judgment, the Judgment has become Final, and the Cliffs Board has approved the Settlement and each of its terms as in the best interest of Cliffs and its shareholders (the “Effective Date”), all Plaintiffs (acting on their own behalf and derivatively on behalf of Cliffs), Cliffs, and each of Cliffs’ shareholders (solely in their capacity as Cliffs Shareholders) shall be deemed to have, and by operation of the Judgment shall have, fully, finally, and forever settled, released, relinquished, extinguished, dismissed with prejudice, and discharged completely each and all of the Individual Defendants, and each and all the Individual Defendants’ respective present or former successors, heirs, executives, employees, agents, insurers, reinsurers, attorneys, advisors, associates, representatives, executors, personal representatives, estates, administrators, assigns, spouses and other members of any Individual Defendant’s immediate family, any entity in which any Individual Defendant or member of any Individual Defendant’s immediate family has or had a controlling interest (directly or indirectly), and any trust of which any Individual Defendant is the settlor or which is for the benefit of any Individual Defendant and/or member(s) of his or her family (“Released Persons”) from any and all claims for relief, suits, debts, demands, rights, actions or causes of action, liabilities, damages, losses, obligations, judgments, fees, expenses, costs, matters, and issues and actions or causes of action of every nature and description whatsoever, whether known or unknown (including Unknown Claims as defined in ¶ 1.26 of the Stipulation), contingent or absolute, suspected or unsuspected, disclosed or undisclosed, matured or unmatured, discoverable or undiscoverable, whether or not concealed or hidden, for damages, injunctive relief, or any other remedy, that have been, or could or might have been, or in the future can or might be asserted by Plaintiffs, Cliffs, and/or any Cliffs shareholder derivatively on behalf of Cliffs against any Released Persons that are based upon, refer to, arise out of concern, or are directly or indirectly related to (i) the claims and

5

allegations contained in the Actions, (ii) any of the facts, transactions, events, occurrences, acts, disclosures, statements, omissions or failures to act that were alleged or that could have been alleged in the Actions; or (iii) the settlement of the Actions, including the payment provided for in this Stipulation, and the reasonable attorneys’ fees, costs, and expenses incurred in defense of the Actions (Released Claims”). Notwithstanding the foregoing, the Released Claims do not include (i) any claims based on any conduct of the Released Persons after April 20, 2016 or (ii) and direct claims belonging to Cliffs shareholders, including without limitation, any claims arising under the federal securities laws. Notwithstanding the foregoing, Released Claims shall not include claims to enforce the terms of the Stipulation or the Settlement. In addition, nothing set forth in the Stipulation or in the Judgment shall constitute a release by any Defendant of any insurer, reinsurer, or any other entity contracted or otherwise obligated to provide insurance or indemnification to any of the Released Persons of any claim arising out of the rights, remedies, duties or obligations provided for in any insurance policy or agreement. Nothing set forth in the Stipulation or the Judgment shall constitute a release by or among the Company and the Individual Defendants or Released Persons of any rights or obligations relating to indemnification or advancement of defense costs, whether arising from the Company’s certificate of incorporation or code of regulations, Ohio law, or any agreement pertaining to indemnification or advancement of defense costs. Co-Lead Plaintiffs (individually and derivatively on behalf of Cliffs) and each of Cliffs’ shareholders (solely in their capacity as Cliffs shareholders) shall be deemed to have, and by operation of the Judgment shall have, covenanted not to sue the Released Persons with respect to the Released Claims, and shall be permanently barred and enjoined from instituting, commencing, or prosecuting the Released Claims against the Released Persons.

2.The releases granted shall be effective as a bar to any or all claims that were alleged or that could or might have been alleged in the Actions by the Plaintiffs, Cliffs, or any Cliffs shareholder derivatively on behalf of Cliffs, which any Plaintiff, Cliffs, or Cliffs shareholder does not know or suspect to exist in his, her, or its favor at the time of the release of the Released Persons, including claims which, if known by him, her, or it, might have affected his, her or its settlement with and release of the Released Persons, or might have affected his, her or its decision not to object to this Settlement (the “Unknown Claims”). With respect to any and all Released Claims, the Parties stipulate and agree that, upon the Effective Date, Plaintiffs, the Individual Defendants, and Cliffs shall expressly waive and relinquish, and each of Cliffs’ shareholders shall be deemed to have, and by operation of the Judgment shall have, expressly waived and relinquished, to the fullest extent permitted by law, any and all provisions, rights, and benefits conferred by any law of the United States or of any state or territory of the United States, or principle of common law, which governs or limits a Person’s release of Unknown Claims, including the provisions, rights and benefits of California Civil

6

Code §1542, which provides:

A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.

and/or conferred by any law of the United States or of any state or territory of the United States, or principle of common law or of international or foreign law, that is similar, comparable, or equivalent in effect to California Civil Code §1542. It is understood that Plaintiffs, Cliffs, or any of Cliffs’ shareholders may hereafter discover facts in addition to or different from those that he, she, or it now knows or believes to be true with respect to the subject matter of the Released Claims (including Unknown Claims), but Plaintiffs and Cliffs shall expressly fully, finally, and forever discharge, settle, and release with prejudice, and each of Cliffs’ shareholders, upon the Effective Date, shall be deemed to have, and by operation of the Judgment shall have fully, finally, and forever discharged, settled and released with prejudice, any and all Released Claims (including Unknown Claims), known or unknown, suspected or unsuspected, contingent or noncontingent, whether or not concealed or hidden, that now exist, or heretofore have existed upon any theory of law or equity now existing or coming into existence in the future, including, but not limited to, conduct which is negligent, grossly negligent, reckless, intentional, with or without malice, or a breach of any duty, law or rule, without regard to the subsequent discovery or existence of such different or additional facts. Plaintiffs and Cliffs acknowledge, and Cliffs’ shareholders shall be deemed by operation of the Judgment to have acknowledged, that the foregoing waiver was separately bargained for and is a key element of the Settlement of which this release is a part.

Upon the Effective Date, each of the Defendants shall be deemed to have, and by operation of the Judgment shall have, fully, finally, and forever settled, released, relinquished, extinguished, dismissed with prejudice, and discharged completely, individually, and collectively each and all of the Plaintiffs and Plaintiffs’ Counsel from all claims (including Unknown Claims) based upon or arising out of the prosecution, assertion, settlement or resolution of the Actions or the Released Claims; provided, however, that such release shall not include claims to enforce the terms of the Stipulation or the Settlement and/or the Judgment entered pursuant thereto.

By order of the Court (a) all proceedings in the Actions, other than those relating to the settlement itself, have been stayed and suspended until further order of the Court; and (b) pending the Court’s determination as to final approval of the Settlement, Plaintiffs and all other Cliffs shareholders are barred and enjoined from commencing, prosecuting, instigating, or in any way participating in the commencement or prosecution of any action asserting any Released Claim against any Released Person.

IV. PLAINTIFFS’ CLAIMS AND BENEFITS OF THE SETTLEMENT

Plaintiffs and Plaintiffs’ Counsel believe that the claims asserted in the Actions have merit and that their investigation supports the claims asserted. Without conceding the merit of any of Defendants’ defenses or the lack of merit of any of their own allegations, and solely in order to avoid the potentially protracted time, expense, and uncertainty associated with continued litigation, including a potential trial and appeal, Plaintiffs and Plaintiffs’ Counsel concluded that it is desirable that the Actions be fully and finally settled in the manner and upon the terms and conditions set forth in the Stipulation. Plaintiffs and Plaintiffs’ Counsel recognize the significant risk, expense, and length of continued proceedings necessary to prosecute the Actions against the Individual Defendants through trial and possible appeal. Plaintiffs’ Counsel also have taken into account the uncertain outcome and the risks of any litigation, especially in complex cases such as the Actions (which are governed by Ohio law and are subject to the protections that law provides for activities and judgments of corporate directors and officers), as well as the difficulties and delays inherent in such complex litigation generally. Plaintiffs and Plaintiffs’ Counsel are also mindful of the inherent problems of proof and possible defenses to the claims asserted in the Actions. Plaintiffs and Plaintiffs’ Counsel believe that the Settlement set forth in the Stipulation confers substantial benefits on the Company. Based on their evaluation and expertise in the area of complex stockholder litigation, Plaintiffs and Plaintiffs’ Counsel have determined that the Settlement is fair, reasonable, and adequate and is in the best interests of Cliffs and its shareholders, and have agreed to settle the Actions upon the terms and subject to the conditions set forth in the Stipulation.

V. DEFENDANTS’ DENIAL OF WRONGDOING AND LIABILITY

Defendants have denied, and continue to deny, all allegations of wrongdoing, fault, liability and/or damage to the Company. Defendants deny that they engaged in or aided and abetted any wrongdoing or violation of the law; deny that they breached any fiduciary duty, including the duty of care or duty of loyalty; deny that they engaged in any of the wrongful acts alleged in the Actions; and deny that they acted in bad faith or improperly in any way. Defendants maintain that they complied with all fiduciary and other legal duties. Defendants believe that all Plaintiffs have failed to meet their burden of pleading with particularity that demand was excused. Nonetheless, Defendants are agreeing to the terms and conditions set forth in the Stipulation solely because they contend and believe the proposed Settlement would eliminate the burden, risk, and expense of further litigation. Defendants have determined that it is desirable and beneficial to them that the claims asserted in the Actions be fully and finally settled and terminated in the manner and upon the terms and conditions set forth in the Stipulation. Defendants have also taken into account the uncertainty, burden, expense, and risks inherent in any litigation, especially in complex cases like the Actions, and are entering into the Stipulation because the Settlement would eliminate the uncertainty, burden, expense and risk of further litigation,

8

and as to Nominal Defendant Cliffs, because the Settlement provides substantial benefits to, and is in the best interests of, Cliffs and its shareholders.

VI. PLAINTIFFS’ COUNSEL’ S ATTORNEYS’ FEES AND REIMBURSEMENT OF EXPENSES

After completing negotiations of the material, substantive terms of the Settlement, Counsel undertook arm’s-length negotiations regarding attorneys’ fees and reimbursement of expenses to be paid to Plaintiffs’ Counsel for the benefits conferred upon the Company and its shareholders as a part of the Settlement. As a result of those negotiations, the Individual Defendants’ D&O insurers have agreed to pay to Plaintiffs’ Lead Counsel (who will, in turn, allocate it among all Plaintiffs’ Counsel) a fee and expense award in the amount of $775,000, subject to Court approval (the “Fee and Expense Award”). The Fee and Expense Award includes fees and expenses incurred by Plaintiffs’ Counsel in connection with the initiation, prosecution and settlement of the Actions. To date, Plaintiffs’ Counsel have not received any payments for their efforts on behalf of Cliffs shareholders, nor have Plaintiffs’ Counsel been reimbursed for their out-of-pocket litigation expenses. The Fee and Expense Award will compensate Plaintiffs’ Counsel for the substantial benefits achieved in the Actions, and the risks of undertaking the prosecution of the Actions on a contingent basis. Plaintiffs’ Counsel will also seek Court approval for the payment to Co-Lead Plaintiffs of a Service Award in the amount of $3,500 each. Any Court-approved Service Award and Service Awards will be funded solely from the Fee and Expense Award.

Any award of attorneys’ fees or expenses and any Service Awards are separate and apart from and are not conditions to the Settlement embodied in the Stipulation or the Judgment. No order or proceeding concerning any fee and expense application or award or any Service Awards, or any modification or reversal on appeal of any fee and expense award or Service Awards, shall constitute grounds for cancellation or termination of the Settlement by any Party or shall otherwise affect the validity or effectiveness of the Settlement.

VII. THE SETTLEMENT HEARING

On July 7, 2016, at 10:00 a.m., the Court will hold the Settlement Hearing before the Honorable Richard J. McMonagle, Cuyahoga County Court of Common Pleas, Old Courthouse, One W. Lakeside Ave., Courtroom 2A, Third Floor, Cleveland, OH 44113. At the Settlement Hearing, the Court will determine: (i) whether the Settlement of the Actions on the terms and conditions provided for in the Stipulation is fair, reasonable, and adequate and in the best interests of Cliffs and its shareholders and should be finally approved by the Court; (ii) whether a Judgment as provided in, and attached as Exhibit C to, the Stipulation, dismissing the Actions on the merits and with prejudice, granting the releases described more fully above, and permanently barring and enjoining Plaintiffs (acting on their own behalf or derivatively on behalf of Cliffs), Cliffs, and each of Cliffs’ shareholders from instituting, commencing, or prosecuting

9

any of the Released Claims against the Released Persons should be entered; (iii) whether the Fee and Expense Award and the Service Awards should be approved; and (iv) such other matters as may be necessary or proper in the circumstances. In the event that the Court does not enter the Judgment approving the Settlement for any reason whatsoever, or if that Judgment is modified, vacated, or reversed on appeal, then the Settlement shall be null and void. The full and complete description of the terms and conditions of the Settlement may be found in the Stipulation, which is on file with the Court.

VIII. RIGHT TO OBJECT TO THE SETTLEMENT AND PROCEDURES FOR DOING SO

You have the right to object to any aspect of the Settlement, the Fee and Expense Award, and/or the Service Awards. If you wish to object or otherwise contest the Settlement, you must do so in writing, and you may also request to be heard at the Settlement Hearing.
