Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

(c) On July 2, 2012, United States Steel Corporation issued a press release announcing that Mr. Mario Longhi was elected, on June 28, 2012, to be Executive Vice President and Chief Operating Officer, effective July 2, 2012. The full text of the press release is filed herewith as Exhibit 99.1.

Prior to his election, Mr. Longhi, age 58, served as President from 2005 to 2006, and President and Chief Executive Officer from 2006 to 2011, of Gerdau Ameristeel Corporation, a producer of long steel products. Prior to joining Gerdau Ameristeel Corporation, Mr. Longhi served in a variety of senior management positions with Alcoa Inc., a producer of aluminum products.

On June 28, 2012, the Compensation & Organization Committee (the Committee) of the Board of Directors approved the terms of an offer letter to Mr. Longhi. Pursuant to the offer letter, he will receive a base annual salary of $820,000 and will be entitled to participate in the Corporation’s Annual Incentive Compensation Program at the target rate of 100 percent of his base annual salary. Additionally, the offer letter provides that Mr. Longhi will participate in the Long-Term Incentive Compensation Program (LTIP). The Committee determined that Mr. Longhi’s 2012 LTIP award will be valued at $2,101,500 on the date of grant, which will be July 3, with 40 percent of the value received in the form of performance awards, 30 percent of the value in the form of stock options and 30 percent of the value in the form of restricted stock units (RSUs). For retention purposes, Mr. Longhi will also receive an additional long-term incentive award valued at $400,000 on the date of grant, which is also July 3, 2012, and which will be divided equally between retention performance awards and retention RSUs. These retention awards will be subject to terms and conditions similar to those applicable to other retention grants, except that in the event of an involuntary termination without cause, the awards will vest in full immediately upon termination, subject to achievement of the relevant performance goals. Additionally, the retention awards do not provide for pro-rata vesting upon termination other than in the case of death or disability.

The offer letter also provides that Mr. Longhi will be entitled to participate in the Corporation’s qualified 401(k) plan and two non-qualified retirement plans (the United States Steel Corporation Supplemental Thrift Program and the United States Steel Corporation Non Tax-Qualified Retirement Account Program), which (non-qualified programs) restore the matching contributions and retirement account contributions that are not permitted to be provided under the qualified 401(k) plan because of limits established under, or required by, the Internal Revenue Code. In addition, the Corporation will establish a Supplemental Account to provide Mr. Longhi with a non tax-qualified pension benefit with respect to the compensation paid to him under the Corporation’s Annual Incentive Compensation Program (and/or similar incentive plans or programs). Under the Supplemental Account, Mr. Longhi will be eligible for book accruals equal to 8.5% of the awards paid (or payable) to him under the Corporation’s Annual Incentive Compensation Program, subject to vesting requirements.

The other provisions of the offer letter set forth benefits that are typically provided to newly hired executives, including health and welfare benefits, tax and financial planning, reasonable relocation expenses, gross-up on the relocation expenses, loss on sale of his primary residence (maximum limited to an amount to be determined by the Corporation), change in control agreement (similar in form to the agreement currently in effect for Mr. Surma, which does not include an excise tax gross-up provision, except that the severance multiple for Mr. Longhi is 2.5 times his base and bonus), and a severance agreement. The severance agreement provides that, if the Corporation terminates his employment, other than for cause, within three years and if he is not entitled to any payment under the change in control agreement, Mr. Longhi will be entitled to receive a lump sum payment equal to the sum of 12 months of base salary and one year of his target bonus under the Annual Incentive Compensation Program.

The foregoing summary of the offer letter is qualified in its entirety by reference to the form of the offer letter, which is filed herewith as Exhibit 10.1, and is incorporated herein by reference.

Other agreements, plans and arrangements contemplated by, discussed in, and/or attached to the offer letter that
