CLEVELAND-CLIFFS INC.

6.75% Senior Secured Note due 2026


1.	Interest

Cleveland-Cliffs Inc., an Ohio corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Note at the rate per annum shown above.

The Company will pay interest semiannually on March 15 and September 15 of each year commencing September 15, 2020. Interest on this Note will accrue (or will be deemed to have accrued) from the most recent date to which interest on this Note or any of its predecessor Notes has been paid or duly provided for or, if no such interest has been paid, from March 13, 2020. The Company shall pay interest on overdue principal, and on overdue premium, if any (plus interest on such interest to the extent lawful), at the rate borne by the Notes to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.


2.	Method of Payment

By no later than 10:00 a.m. (New York City time) on the date on which any principal of, premium, if any, or interest on any Note is due and payable, the Company shall deposit with the Trustee or the Paying Agent money sufficient to pay such principal, premium, if any, and/or interest when due. The Company will pay interest (except Defaulted Interest) to the Persons who are registered Holders of Notes at the close of business on the March 1 or September 1 next preceding the interest payment date even if Notes are cancelled, repurchased or redeemed after the record date and on or before the interest payment date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Company will pay principal, premium, if any, and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of Notes represented by a Global Note (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company or any successor depository. The Company will make all payments in respect of a Definitive Note (including principal, premium, if any, and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on the Notes may also be made, in the case of a Holder of at least $1,000,000 aggregate principal amount of Notes represented by Definitive Notes, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee at the Corporate Trust Office or the Paying Agent at the Corporate Trust Office to such effect designating such account no later than 15 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).


3.	Paying Agent and Registrar

Initially, U.S. Bank National Association (the “Trustee”) will act as Trustee, Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar, co-registrar or transfer agent without notice to any Holder. The Company or any of its domestically organized, Wholly-Owned Subsidiaries may act as Paying Agent, Registrar or co- registrar.


4.	Indenture

The Company issued the Notes under an Indenture, dated as of March 13, 2020 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “Indenture”), among the Company, the Guarantors, the Trustee and the First Lien Notes Collateral Agent. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S.C. §§ 77aaa-77bbbb) (the “TIA”), although the Indenture is not required to be qualified under the TIA. Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Notes are subject to all terms and provisions of the Indenture, and Holders are referred to the Indenture and the TIA for a statement of those terms.

The Notes are senior secured obligations of the Company. The aggregate principal amount of Notes that may be authenticated and delivered under the Indenture is unlimited. This Note is one of the 6.75% Senior Secured Notes

due 2026 referred to in the Indenture. The Notes are Additional Notes under the Indenture and the Company shall be entitled to issue further Additional Notes pursuant to Section 2.01 of the Indenture. The Initial Notes and Additional Notes are treated as a single class of securities under the Indenture and shall be secured by first-priority and second-priority Liens and security interests, subject to Permitted Liens, in the Collateral. The Indenture imposes certain restrictions on the incurrence of certain liens, sale-leaseback transactions, and the consummation of mergers and consolidations. The Indenture also imposes requirements with respect to the provision of financial information and the provision of guarantees of the Notes by certain subsidiaries.

To guarantee the due and punctual payment of the principal, premium, if any, and interest (including post-filing or post-petition interest) on the Notes and all other amounts payable by the Company under the Indenture, the Notes and the Collateral Documents (including expenses and indemnification) when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Notes and the Indenture, the Guarantors have as primary obligors and not merely as sureties, irrevocably and unconditionally guaranteed (and future guarantors, together with the Guarantors, will unconditionally guarantee), jointly and severally, on a senior secured basis, all such obligations pursuant to the terms of the Indenture.


5.	Redemption and Prepayment

Prior to March 15, 2022 the Company may, at any time and from time to time, redeem in the aggregate up to 35% of the aggregate principal amount of the Notes originally issued under the Indenture with the net cash proceeds of one or more Equity Offerings by the Company at a redemption price (expressed as a percentage of principal amount thereof) of 106.75%, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided, however, that:

(1)at least 65% of the aggregate principal amount of Notes originally issued under the Indenture (excluding Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and

(2)the redemption occurs within 90 days of the date of the closing of such Equity Offering.

Prior to March 15, 2022, the Company may, at any time and from time to time, also redeem all or a part of the Notes, at a redemption price equal to 100.000% of the principal amount of Notes redeemed plus the Applicable Premium, plus accrued and unpaid interest to, but excluding, the Redemption Date.

On or after March 15, 2022, the Company may on one or more occasions redeem all or a part of the Notes at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest on the Notes redeemed, to, but excluding, the applicable Redemption Date, if redeemed during the twelve-month period beginning on each date set forth below, subject to the rights of Holders of Notes on the relevant record date to receive interest on the relevant interest payment date:



Period		Redemption price
March 15, 2022		105.063%
March 15, 2023		103.375%
March 15, 2024		101.688%
March 15, 2025 and thereafter		100.000%

Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable Redemption Date.

The Company will deliver notice of redemption to each Holder at least 30 days but not more than 60 days before a Redemption Date.

“Adjusted Treasury Rate” means, with respect to any Redemption Date, (i) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted

to constant maturity under “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after March 15, 2022, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month) or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date, in each case calculated on the third Business Day immediately preceding the Redemption Date, plus 0.50%.

“Applicable Premium” means, with respect to any Note at any Redemption Date the excess of (if any) (A) the present value at such Redemption Date of (1) the redemption price of such Note on March 15, 2022 plus (2) all required remaining scheduled interest payments due on such note through March 15, 2022, excluding in each case accrued and unpaid interest to, but excluding, the Redemption Date, computed by the Company using a discount rate equal to the Adjusted Treasury Rate, over (B) the principal amount of such Note on such Redemption Date:

“Comparable Treasury Issue” means the United States Treasury security selected by the Company as having a maturity comparable to the remaining term of the Notes from the Redemption Date to March 15, 2022, that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a maturity most nearly equal to March 15, 2022.

“Comparable Treasury Price” means, with respect to any Redemption Date, if clause (ii) of the definition of “Adjusted Treasury Rate” is applicable, the average of three, or such lesser number as is obtained by the Company, Reference Treasury Dealer Quotations for such Redemption Date.

“Reference Treasury Dealer” means Credit Suisse Securities (USA) LLC and its respective successors and assigns, and any other nationally recognized investment banking firm selected by the Company and identified to the Trustee by written notice from the Company that is a primary U.S. Government securities dealer.

“Reference Treasury Dealer Quotations” means, with respect to the Reference Treasury Dealer and any Redemption Date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Company by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day immediately preceding such Redemption Date.

“Treasury Rate” means the yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15(519) which has become publicly available at least two Business Days prior to the date fixed for redemption (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the then remaining average life to March 15, 2022, provided, however, that if the average life to March 15, 2022, of the Notes is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if the average life to March 15, 2022, of the notes is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used.

Prior to the mailing or delivery of any notice of redemption of the Notes, the Company shall deliver to the Trustee an Officer’s Certificate stating that the conditions precedent to the right of redemption have occurred. Any such notice to the Trustee may be cancelled at any time prior to notice of such redemption being mailed to any Holder and shall thereby be void and of no effect.

The Company may acquire Notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise, in accordance with applicable securities laws, so long as such acquisition does not otherwise violate the terms of the Indenture.

Except as set forth in the next succeeding paragraph, the Company is not required to make any mandatory repurchase, redemption or sinking fund payments with respect to the Notes.


6.	Change of Control Triggering Event

In accordance with Section 3.06 of the Indenture, the Company shall be required to offer to purchase Notes upon the occurrence of a Change of Control Triggering Event. Any Holder of Notes shall have the right, subject to certain conditions specified in the Indenture, to cause the Company to repurchase all or any part of the Notes of such Holder at a purchase price equal to 101.0% of the principal amount of the Notes to be repurchased plus accrued and unpaid interest to, but excluding, the date of repurchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date that is on or prior to the date of purchase) as provided in, and subject to the terms of, the Indenture.


7.	Denominations; Transfer; Exchange

The Notes are in registered form without coupons in minimum denominations of principal amount of $2,000 and whole multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay a sum sufficient to cover any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange of any Note (A) for a period beginning (1) 15 days before the mailing of a notice of an offer to repurchase or redeem Notes and ending at the close of business on the day of such mailing or (2) 15 days before an interest payment date and ending on such interest payment date or (B) called for redemption, except the unredeemed portion of any Note being redeemed in part.


8.	Persons Deemed Owners

The registered Holder of this Note shall be treated as the owner of it for all purposes (except as otherwise provided in the Indenture).


9.	Unclaimed Money

If money for the payment of principal, premium, if any, or interest on any Note remains unclaimed for two years after such principal, premium, if any, or interest has become due and payable, the Trustee or any Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company for payment as general creditors unless an abandoned property law designates another person and not to the Trustee for payment.


10.	Defeasance

Subject to certain exceptions and conditions set forth in the Indenture, the Company at any time may terminate some or all of its and the Guarantors’ obligations under the Notes, the Indenture and the Collateral Documents if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal, premium, if any, and interest on the Notes to redemption or maturity, as the case may be.


11.	Amendment, Supplement, Waiver

Subject to certain exceptions set forth in the Indenture, (i) the Indenture, the Notes, the Guarantees and the Collateral Documents may be amended or supplemented by the Company, Guarantors and Trustee with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and (ii) any default (other than with respect to nonpayment of interest or premium on, or the principal of the Notes or in respect of a provision that cannot be amended without the consent of each Holder affected, or in certain cases described in the Indenture and the Collateral Documents, the consent of Holders of at least 75% in aggregate principal amount of the Notes then outstanding) or noncompliance with any provision may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes. Subject to the requirements of and certain exceptions set forth in the Indenture, without the consent of any Holder, the Company, the Trustee and the Guarantors (with respect to its Guarantee) may amend or supplement the Indenture, the Notes, the Guarantees or the Collateral Documents: (1) to cure any ambiguity, defect or inconsistency; (2) to provide for uncertificated Notes in addition to or in place of certificated Notes; (3) to provide for the assumption of the Company’s or a Guarantor’s obligations to Holders of Notes and Guarantees in the case of a merger or consolidation or sale of all or substantially all of the Company’s or such Guarantor’s assets, as applicable; (4) to make any change that would provide any additional rights or benefits to the Holders of Notes or that does not adversely affect the legal rights hereunder or under the Notes, the Guarantees and the Collateral Documents of any such Holder; (5) to conform the text of the Indenture, Guarantees, the Notes or

the Collateral Documents to any provision of the “Description of the Secured Notes” section of the Offering Memorandum; (6) to provide for the issuance of Additional Notes in accordance with the limitations set forth in the Indenture as of the date hereof; (7) to allow any Guarantor to execute a supplemental indenture substantially in the form of Exhibit B to the Indenture and/or a Guarantee with respect to the Notes; (8) to add any additional obligors under the Indenture, the Notes or the Guarantees; (9) to secure any Additional First Lien Indebtedness or Additional Secured Indebtedness permitted to be incurred under the Indenture pursuant to the Collateral Documents and to appropriately include the same in the Pari Passu Intercreditor Agreement and the ABL Intercreditor Agreement; (10) to add additional Collateral to secure the Notes; (11) to comply with the provisions under Section 4.01 of the Indenture; and (12) to evidence and provide for the acceptance of an appointment by a successor Trustee.

By accepting a Note, each Holder waives and releases all such liability. The waiver and release are a part of the consideration for the issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws.

No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption or purchase and reliance may be placed only on the other identification numbers placed thereon.
