1.Purpose. The United States Steel Corporation Deferred Compensation Program for Non-Employee Directors, a program under the United States Steel Corporation 2016 Omnibus Incentive Compensation Plan, is intended to enable the Corporation to attract and retain non-employee Directors and to enhance the long-term mutuality of interest between such Directors and shareholders of the Corporation.

(a)Base Retainer means the means that portion of a Participant’s compensation that is fixed and paid without regard to his/her attendance at meetings, as such amount is established for or during the Program Year, exclusive of fees paid to chairs of committees or the Board.

(b)Beneficiary or Beneficiaries means a person or persons or other entity designated on a Beneficiary Designation Form by a Participant as allowed in Section 5(c) of this Program to receive Deferred Stock Unit Benefit payments. If there is no valid designation by the Participant, or if the designated Beneficiary or Beneficiaries fail to survive the Participant or otherwise fail to take the Deferred Stock Unit Benefit, the Participant’s Beneficiary is the Participant’s surviving spouse or, if there is no surviving spouse, the Participant’s estate.

(i)Deferred Stock Unit Account means that bookkeeping record established for each Participant to reflect the status of his/her Deferred Stock Unit Benefits under this Program. A Deferred Stock Unit Account is established only for purposes of measuring a Deferred Stock Unit Benefit and not to segregate assets or to identify assets that may or must be used to satisfy a Deferred Stock Unit Benefit. A Deferred Stock Unit Account will be credited with that portion of the Participant’s Retainer Fee deferred as Deferred Stock Units according to an Election Form and according to Section 4 of this Program. A Deferred Stock Unit Account will also be adjusted periodically with amounts specified under subsections 4(a)(ii) through 4(a)(iii) of this Program.

(l)Election Date means the date established by this Program as the date before which a Participant must submit a valid Election Form to the Committee. For the Program Year during which an individual first becomes a Participant, the Election Date is the earlier of (i) 30 days following the date on which the individual becomes a Participant and (ii) December 31 of such Program Year. For each subsequent Program Year, the Election Date is December 31 of the preceding calendar year. Despite the two preceding sentences, the Committee may set an earlier date as the Election Date for any Program Year.

(m)Election Form means a document governed by the provisions of Section 3 of this Program by which a Participant elects the portion of his or her Retainer Fee to be deferred as Deferred Stock Units and designates a Beneficiary.

(s)Terminate, Terminating, or Termination, with respect to a Participant, means cessation of his/her relationship with the Corporation as a Director whether by resignation, retirement, death, disability or severance for any other reason. The terms “Terminate,” “Terminating,” and “Termination,” when used in the context of a condition to, or timing of, payment hereunder, shall be interpreted to mean a “separation from service” as that term is used in Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”).

3.Election. A deferral election is valid when an Election Form is completed, signed by the Participant, and received by the Committee or its designee. Deferral elections are governed by the provisions of this section.

(a)A Participant may elect a Deferred Stock Unit Benefit for any Program Year, subject to the Election Date requirements, if he/she is a Participant at the beginning of that Program Year or becomes a Participant during the Program Year.

(b)Before each Program Year’s Election Date, each Participant will be provided with an Election Form. A Participant may elect on or before the Election Date to defer the receipt of all or part of his/her Retainer Fee for the Program Year in the form of a Deferred Stock Unit Benefit under the Program; provided, however, that no

(c)A Participant may not revoke or amend an Election Form after the Program Year begins with respect to such Program Year, and no re-allocation between fixed and variable compensation (if any) otherwise payable during the Program Year shall be permitted to indirectly amend such Election Form or the amount of Retainer Fees subject thereto. Any revocation before the beginning of the Program Year is the same as a failure to submit an Election Form. Any writing signed by a Participant expressing an intention to revoke his/her Election Form and delivered to the Committee or its designee before the close of business on the relevant Election Date is a revocation.

(a)Deferred Stock Unit Benefits will consist of Deferred Stock Units and will be recorded in a Deferred Stock Unit Account for each Participant. A “Deferred Stock Unit” shall mean a book-entry unit equal in value to one share of Common Stock on the date specified below. Each Deferred Stock Unit will increase or decrease in value by the same amount and with the same frequency as the fair market value of a share of Common Stock. Each Deferred Stock Unit Account will be credited or adjusted as follows:

(i)Crediting. The Participant’s Deferred Stock Unit Account will be credited with a quantity of Deferred Stock Units, including fractional units, as of the date the award of Deferred Stock Units would have otherwise vested.

(ii)Cash Dividends. Each Deferred Stock Unit Account will be credited each calendar quarter, on the date on which cash dividends are reinvested under the Corporation’s dividend reinvestment and stock purchase plans (the “Investment Date”), with a quantity of additional Deferred Stock Units, including fractional units, determined by dividing (A) the Dividend Payment Amount by (B) the Stock Purchase Price. “Dividend Payment Amount” means the product of the number of Deferred Stock Units in the Deferred Stock Unit Account on the dividend payment date times the amount of the cash dividend payable on a share of Common Stock. “Stock Purchase Price” means the closing price of a share of Common Stock on the NYSE on the most recent trading day preceding the Investment Date.

(iii)Stock Dividends, Stock Splits and Reverse Stock Splits. In the event of a stock dividend, stock split, reverse stock split or similar event affecting the Common Stock, the number of Deferred Stock Units in the Deferred Stock Unit Account shall be adjusted in an equitable and proportional manner to reflect such event in order to prevent the dilution or enlargement of Participant’s rights.

(b)If a trust is established under Section 6(b), an electing Participant may advise the trustee under the governing trust agreement as to the voting of shares of the Common Stock allocated to that Participant’s separate account under the trust according to this subsection and provisions of the governing trust agreement. Before each annual or special meeting of the Corporation’s shareholders, the trustee under the governing trust agreement must furnish each Participant with a copy of the proxy solicitation and other relevant material for the meeting as furnished to the trustee by the Corporation, and a form addressed to the trustee

requesting the Participant’s confidential advice as to the voting of shares of the Common Stock allocated to his/her account as of the valuation date established under the governing trust agreement preceding the record date.

(a)Except as set forth in Section 5(d), a Deferred Stock Unit Benefit will be distributed in shares of Common Stock equal to the number of, the whole, Deferred Stock Units credited to the Participant’s Deferred Stock Unit Account; provided, however, cash will be paid in lieu of fractional shares of the Common Stock otherwise distributable, calculated on the basis of the closing price of a share of Common Stock on the NYSE on the date of Termination (or if such date is not a trading day on the immediately preceding trading day).

(c)Deferred Stock Unit Benefits may not be assigned by a Participant or Beneficiary. A Participant may use a Beneficiary Designation Form to designate one or more Beneficiaries for all of his/her Deferred Stock Unit Benefits; such designations are revocable. Each Beneficiary will receive his/her portion of the Participant’s otherwise unpaid Deferred Stock Unit Account on the scheduled payment date as set forth in Section 5(b).

(d)Upon the occurrence of a Change in Control resulting in a Participant’s Termination as of or within the one-year period following such Change in Control, the Corporation shall pay such Participant, on or before the fifth business day following such Termination, cash in an aggregate amount equal to the value of such Participant’s Deferred Stock Unit Account on the date of the Change in Control, as determined using the higher of the closing price of the Common Stock on the NYSE on such date or the highest per-share price actually paid in connection with the consummation of such Change in Control. For purposes of this Program, “Change in Control” shall mean a change in control of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), whether or not the Corporation is then subject to such reporting requirement; provided, that, without limitation, such a change in control shall be deemed to have occurred if:

(i)any person (as defined in Sections 13(d) and 14(d) of the Exchange Act) (a “Person”) is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Corporation representing twenty percent (20%) or more of the combined voting power of the Corporation’s then outstanding voting securities; provided, however, that for purposes of this Program the term “Person” shall not include (i) the Corporation or any of its subsidiaries, (ii) a trustee or other fiduciary holding securities under an employee benefit plan of the Corporation or any of its subsidiaries, (iii) an underwriter temporarily holding securities pursuant to an offering of such securities, or (iv) a corporation owned, directly or indirectly, by the stockholders of the Corporation in substantially the same proportions as their ownership of stock of the Corporation; or

(ii)the following individuals cease for any reason to constitute a majority of the number of directors then serving: individuals who, on the date hereof, constitute the Board and any new director (other than a director whose initial assumption of office is in connection with an actual or threatened election contest including but not limited to a consent solicitation, relating to the election of directors of the Corporation) whose appointment or election by the Board or nomination for election by the Corporation’s stockholders was approved by a vote of at least two-thirds (2/3) of the directors then still in office who either were directors on the date hereof or whose appointment, election or nomination for election was previously so approved; or

(iii)there is consummated a merger or consolidation of the Corporation or a subsidiary thereof with any other corporation, other than a merger or consolidation which would result in the holders of the voting securities of the Corporation outstanding immediately prior thereto holding securities which represent immediately after such merger or consolidation at least 50% of the combined voting power of the voting securities of the entity surviving the merger or consolidation (or the parent of such surviving entity) or the shareholders of the Corporation approve a plan of complete liquidation of the Corporation, or there is consummated the sale or other disposition of all or substantially all of the Corporation’s assets.

Notwithstanding anything to the contrary herein, in no event will a Change in Control be deemed to have occurred for purposes of this Section 5(d) if the transaction is not also a “change in the ownership or effective control of” the Corporation or “a change in the ownership of a substantial portion of the assets of” the Corporation as determined under Treasury Regulation Section 1.409A-3(i)(5).

(a)The Program is unfunded. A Deferred Stock Unit Benefit is at all times solely a contractual obligation of the Corporation. A Participant and his/her Beneficiaries have no right, title or interest in the Deferred Stock Unit Benefits or any claim against them. Except according to Section 6(b), the Corporation will not segregate any funds or assets for Deferred Stock Unit Benefits nor issue any notes or security for the payment of any Deferred Stock Unit Benefit.

(b)The Corporation may establish a grantor trust and transfer to that trust shares of Common Stock or other assets. The governing trust agreement must require a separate account to be established for each electing Participant. The governing trust agreement must also require that all Corporation assets held in trust remain at all times subject to the Corporation’s judgment creditors.

8.Claims Against Participant’s Deferred Stock Unit Benefits. A Deferred Stock Unit Account relating to a Participant under this Program is not subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, or charge, and any attempt to do so is void. A Deferred Stock Unit Benefit is not subject to attachment or legal process for a Participant’s debts or other obligations. Nothing contained in this Program gives any Participant any interest, lien or claim against any specific asset of the

10.Notices. Notices and elections under this Program must be in writing. A notice or election is deemed delivered if it is delivered personally or if it is mailed by registered or certified mail to the person at his/her last known business address.

Headings and captions are only for convenience; they do not have substantive meaning.
