(For the avoidance of doubt, the minimum amount of General Non-Compete Benefits payable to Executive who is under age 55 as of the Date of Termination shall not include the value of Executive’s forfeitable deferred common stock units credited to Executive’s deferral account under the AIP or the value of any forfeitable restricted stock units or forfeitable shares of restricted stock awarded to Executive under the Equity Award Plan).

If Executive dies 12 or more months after the termination of Executive’s employment with Nucor, then Nucor’s obligations to make any installment payments under this Section 4(c) will automatically terminate without the necessity of Nucor providing notice, written or otherwise. If Executive is employed by Nucor at the time of Executive’s death, Nucor’s obligations to make any payments of the monthly installments pursuant to this Section 4(c) will automatically terminate and Executive’s estate and executors will have no rights to any such payments.

5.Change in Control Non-Compete Benefits.

(a)Executive shall be entitled to receive Change in Control Non-Compete Benefits from the Company as provided in this Section 5, in lieu of General Non-Compete Benefits under Section 4, if (i) a Change in Control has occurred and Executive’s employment with the Nucor is involuntarily terminated by Nucor or is voluntarily terminated by Executive for Good Reason, provided that, (x) such termination occurs after such Change in Control and on or before the second anniversary thereof, or (y) the termination occurs before such Change in Control but Executive can reasonably demonstrate that such termination or the event or action causing Good Reason to occur, as applicable, occurred at the request of a third party who had taken steps reasonably calculated to effect a Change in Control, and (ii) on or before the Date of Termination, Executive executes a separation and release agreement in form and content reasonably satisfactory to the Committee releasing any and all claims Executive has or may have against Nucor as of the Date of Termination. Change in Control Non-Compete Benefits shall not be payable if Executive terminates employment with the Company due to Executive’s death, disability, voluntary retirement or resignation without Good Reason, provided that Executive may be entitled to the General Non-Compete Benefits pursuant to Section 4.

(b)If Executive’s employment is terminated in circumstances entitling Executive to Change in Control Non-Compete Benefits as provided in Section 5(a), Nucor Corporation shall pay Executive, in a single lump sum payment in cash, and subject to Section 26, within 10 days of the Date of Termination, Change in Control Non-Compete Benefits in an amount equal to the sum of:

(i)the product of (A) 2 multiplied by (B) the sum of (1) Executive’s Base Salary and (2) the greater of (x) 150% of Executive’s Base Salary and (y) the average performance award under the AIP (including any deferred portion thereof but excluding the related “Deferral Incentive” (as defined in the AIP)) for the 3 fiscal years prior to Executive’s Date of Termination, provided for purposes of calculating such average, the performance award under the AIP for any year in such 3 fiscal year period Executive did

not hold Executive’s current position shall be equal to the performance award under the AIP for such year for Executive’s position as a percentage of base salary multiplied by Executive’s Base Salary; and

(ii)if Executive’s Date of Termination occurs prior to the annual grant date under the Equity Award Plan (which date is currently June 1) for the year in which such Date of Termination occurs, an amount equal to the aggregate dollar value of the base equity award and the performance-based equity award Executive would have become entitled to receive under the Equity Award Plan for such year if Executive’s employment had continued to the annual grant date.

(c)Executive’s Change in Control Non-Compete Benefits shall be reduced and offset, but not below zero, by any severance pay or pay in lieu of notice required to be paid to Executive under applicable law, including, without limitation, the Worker Adjustment and Retraining Notification Act or any similar state or local law.

(d)If Executive is entitled to Change in Control Non-Compete Benefits pursuant to Section 5(a), Executive shall continue to be provided with medical, dental, and prescription drug benefits comparable to the benefits provided to Executive immediately prior to the Date of Termination, or if more favorable to Executive, the Change in Control, for the duration of the Change in Control Period with the same contribution rate for which Executive would have been responsible if Executive had remained employed through the Change in Control Period. Any benefits so provided shall not be considered a continuation of coverage required under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended; provided that, if Executive becomes reemployed with another employer and is eligible to receive medical, dental or prescription drug insurance coverage under another employer-provided plan (regardless of whether Executive actually enrolls under such coverage), then the medical, dental or prescription drug insurance benefits provided pursuant to this Section 5(d) shall be secondary to those provided under such other plan during such applicable period of eligibility.

(e)Upon a Change in Control, the obligations of Nucor Corporation to pay and provide the Change in Control Non-Compete Benefits described in this Section 5 shall be absolute and unconditional and shall not be affected by any circumstances, including, without limitation, any set-off, counterclaim, recoupment, defense or other right which Nucor may have against Executive. In no event shall Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to Executive under any of the provisions of this Agreement, nor shall the amount of any payment hereunder be reduced by any compensation earned by Executive as a result of employment by another employer, except with respect to the continued welfare benefits provided under Section 5(d).

(f)In exchange for Nucor Corporation’s agreement to make Executive eligible for the compensation, payments and benefits set forth in this Agreement, and other good and valuable consideration, Executive agrees to strictly abide by the terms of Sections 10 through 15 of this Agreement.

6.Duties and Responsibilities; Best Efforts. While employed by Nucor, Executive shall perform such duties for and on behalf of Nucor as may be determined and assigned to Executive from time to time by the Chief Executive Officer of Nucor Corporation or the Board. Executive shall devote Executive’s full time and best efforts to the business and affairs of Nucor. During the term of Executive’s

employment with Nucor, Executive will not undertake other paid employment or engage in any other business activity without the prior written consent of the Board.

7.Employment at Will. The parties acknowledge and agree that this Agreement does not create employment for a definite term and that Executive’s employment with Nucor is at will and terminable by Nucor or Executive at any time, with or without cause and with or without notice, unless otherwise expressly set forth in a separate written agreement executed by Executive and Nucor after the Effective Date.

8.Change in Executive’s Position. In the event that Nucor transfers, demotes, promotes, or otherwise changes Executive’s compensation or position with Nucor, the restrictions and post-termination obligations set forth in Sections 10 through 15 of this Agreement shall remain in full force and effect. Executive acknowledges and agrees that the benefits and opportunities being provided to Executive under this Agreement are sufficient consideration for Executive’s compliance with these obligations.

9.Recognition of Nucor’s Legitimate Interests. Executive understands and acknowledges that Nucor competes in North America and throughout the world in Business. As part of Executive’s employment with Nucor, Executive acknowledges Executive will continue to have access to and gain knowledge of significant secret, confidential and proprietary information of the full range of operations of Nucor. In addition, Executive will continue to have access to and contact with vendors, suppliers, customers and prospective vendors, suppliers and customers of Nucor, in which capacity Executive is expected to develop good relationships with such vendors, suppliers, customers and prospective vendors, suppliers and customers, and will gain intimate knowledge regarding the products and services of Nucor. Executive recognizes and agrees that Nucor has spent and will continue to spend substantial effort, time and money in developing relationships with its customers, suppliers and vendors, that many customers, suppliers and vendors are long term customers, suppliers and vendors of Nucor, and that all customers, suppliers, vendors and accounts that Executive may deal with during Executive’s employment with Nucor, including any customers, suppliers, vendors and accounts acquired for Nucor by Executive, are the customers, suppliers, vendors and accounts of Nucor. Executive acknowledges that Nucor’s competitors, customers, suppliers and vendors would obtain an unfair advantage if Executive disclosed Secret Information or Confidential Information to a competitor, customer, supplier or vendor, used it on a competitor’s, customer’s, supplier’s or vendor’s behalf (except for the benefit of Nucor), or if Executive were able to exploit the relationships Executive develops as an employee of Nucor to Solicit or direct business on behalf of a competitor, customer, supplier or vendor.

10.Covenant Regarding Nucor’s Secret Information.

(a)Executive recognizes and agrees that Executive will have continued access to Secret Information. Executive agrees that unless Executive is expressly authorized by Nucor in writing, Executive will not use or disclose or allow to be used or disclosed Secret Information. This covenant shall survive until the Secret Information is generally known in the industry through no act or omission of the Executive or until Nucor knowingly authorizes the disclosure of or discloses the Secret Information, without any limitations on use or confidentiality. Executive acknowledges that Executive did not have knowledge of Secret Information prior to Executive’s employment with Nucor and that the Secret Information does not include Executive’s general skills and know-how.

(b)Notwithstanding anything to the contrary set forth in this Agreement, pursuant to the federal Defend Trade Secrets Act of 2016, an individual will be immune from criminal or civil liability under any federal or state trade secret law for (i) the disclosure of a Trade Secret that is made (A) in confidence to a federal, state, or local government official, either directly or indirectly,

or to an attorney; and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) a disclosure that is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. An individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the Trade Secret to the attorney of the individual and use the Trade Secret information in the court proceeding, if the individual files any document containing the Trade Secret under seal and does not disclose the Trade Secret, except pursuant to court order.

11.Agreement to Maintain Confidentiality; Non-Disparagement.

(a)During Executive’s employment with Nucor and at all times after the termination of Executive’s employment with Nucor, (i) Executive covenants and agrees to treat as confidential all Confidential Information submitted to Executive or received, compiled, developed, designed, produced, accessed, or otherwise discovered by the Executive from time to time while employed by Nucor, and (ii) Executive will not disclose or divulge the Confidential Information to any person, entity, firm or company whatsoever or use the Confidential Information for Executive’s own benefit or for the benefit of any person, entity, firm or company other than Nucor. This restriction will apply throughout the world; provided, however, that if the restrictions of this Section 11(a) when applied to any specific piece of Confidential Information would prevent Executive from using Executive’s general knowledge or skills in competition with Nucor or would otherwise substantially restrict the Executive’s ability to fairly compete with Nucor, then as to that piece of Confidential Information only, the scope of this restriction will apply only for the Restrictive Period (as defined below).

(b)Executive specifically acknowledges that the Confidential Information, whether reduced to writing or maintained in the mind or memory of Executive, and whether compiled or created by Executive, Nucor, or any of its customers, suppliers or vendors or prospective customers, suppliers or vendors, derives independent economic value from not being readily known to or ascertainable by proper means by others who could obtain economic value from the disclosure or use of the Confidential Information. Executive also acknowledges that reasonable efforts have been put forth by Nucor to maintain the secrecy of the Confidential Information, that the Confidential Information is and will remain the sole property of Nucor or any of its customers, suppliers or vendors or prospective customers, suppliers or vendors, as the case may be, and that any retention and/or use of Confidential Information during or after the termination of Executive’s employment with Nucor (except in the regular course of performing Executive’s duties hereunder) will constitute a misappropriation of the Confidential Information belonging to Nucor. Executive acknowledges and agrees that if Executive (i) accesses Confidential Information on any Nucor computer system within 30 days prior to the effective date of Executive’s voluntary resignation of employment with Nucor and (ii) transmits, copies or reproduces in any manner such Confidential Information to or for herself or any person or entity not authorized by Nucor to receive such Confidential Information, or deletes any such Confidential Information, Executive is exceeding Executive’s authorized access to such computer system. Notwithstanding anything to the contrary set forth herein, this Agreement shall not be construed to restrict Executive from communications or disclosures that are protected under federal law or regulation.

(c)Executive agrees not to make any statements, written (including electronically) or verbal, or cause or encourage others to make any statements, written (including electronically) or verbal, that defame, disparage or in any way criticize the personal or business reputation, practices, or conduct of Nucor, or any of Nucor’s directors, managers, officers, employees, agents or representatives. Executive acknowledges and agrees that this prohibition extends to statements,

written (including electronically) or verbal, made to anyone, including but not limited to the general public, the news media, investors, potential investors, any board of directors, industry analysts, competitors, strategic partners, vendors, customers or Nucor employees, agents or representatives (past and present), however, nothing set forth in this Section 11(c) prohibits Executive from communicating, without notice to or approval by Nucor Corporation, with any United States federal government agency about a potential violation of a United States federal law or regulation.

12.Noncompetition. Executive hereby agrees that for the duration of Executive’s employment with Nucor and for the duration of the Restrictive Period, Executive will not, either individually or by or through any agent, representative, entity, employee or otherwise, within the Restricted Territory:

(a)engage in any Competing Business Activity, whether as an owner, partner, shareholder, member, lender, employee, consultant, agent, co-venturer or in any other capacity;

(c)provide any public endorsement of, or otherwise lend Executive’s name for use by, any person or entity engaged in any Competing Business Activity; or

(d)Solicit or attempt to influence any Prospective Customer or Supplier to purchase products or services from an entity other than Nucor or to provide products or services to an entity other than Nucor, which are the same or substantially similar to, or otherwise in competition with,

14.Antipiracy.

(a)Executive agrees for the duration of the Restrictive Period, Executive will not, either individually or through or by any agent, representative, entity, employee or otherwise, solicit, encourage, contact, or attempt to induce any employees of Nucor (i) with whom Executive had regular contact with at the time of, or at any time during the 12 month period immediately prior to, the Date of Termination, and (ii) who are employed by Nucor at the time of the encouragement, contact or attempted inducement, to end their employment relationship with Nucor.

(b)Executive further agrees for the duration of the Restrictive Period not to hire, or to assist any other person or entity to hire, any employees described in Section 14(a) of this Agreement.

15.Assignment of Intellectual Property Rights.

(a)Executive hereby assigns to Nucor Corporation Executive’s entire right, title and interest, including copyrights and patents, in any idea, invention, design of a useful article (whether the design is ornamental or otherwise), work product and any other work of authorship (collectively the “Developments”), made or conceived solely or jointly by Executive at any time during Executive’s employment by Nucor (whether prior or subsequent to the execution of this Agreement), or created wholly or in part by Executive, whether or not such Developments are patentable, copyrightable or susceptible to other forms of protection, where the Developments: (i) were developed, invented, or conceived within the scope of Executive’s employment with Nucor; (ii) relate to Nucor’s actual or demonstrably anticipated research or development; or (iii) result from any work performed by Executive on Nucor’s behalf. Executive shall disclose any Developments to Nucor’s management within 30 days following Executive’s development, making or conception thereof.

(b)The assignment requirement in Section 15(a) shall not apply to an invention that Executive developed entirely on Executive’s own time without using Nucor’s equipment, supplies, facilities or Secret Information or Confidential Information except for those inventions that (i) relate to Nucor’s business or actual or demonstrably anticipated research or development, or (ii) result from any work performed by Executive for Nucor.

(c)Executive will, within 3 business days following Nucor’s request, execute a specific assignment of title to any Developments to Nucor Corporation or its designee, and do anything else reasonably necessary to enable Nucor Corporation or its designee to secure a patent, copyright, or other form of protection for any Developments in the United States and in any other applicable country.

(d)Nothing in this Section 15 is intended to waive, or shall be construed as waiving, any assignment of any Developments to Nucor implied by law.

16.Severability. It is the intention of the parties to restrict the activities of Executive only to the extent reasonably necessary for the protection of Nucor’s legitimate interests. The parties specifically covenant and agree that should any of the provisions in this Agreement be deemed by a court of competent jurisdiction too broad for the protection of Nucor’s legitimate interests, the parties authorize the court to

narrow, limit or modify the restrictions herein to the extent reasonably necessary to accomplish such purpose. In the event such limiting construction is impossible, such invalid or unenforceable provision shall be deemed severed from this Agreement and every other provision of this Agreement shall remain in full force and effect.

17.Enforcement. Executive understands and agrees that any breach or threatened breach by Executive of any of the provisions of Sections 10 through 15 of this Agreement shall be considered a material breach of this Agreement, and in the event of such a breach or threatened breach of this Agreement, Nucor shall be entitled to pursue any and all of its remedies under law or in equity arising out of such breach. If Nucor pursues either a temporary restraining order or temporary injunctive relief, then Executive agrees to expedited discovery with respect thereto and waives any requirement that Nucor post a bond. Executive further agrees that in the event of Executive’s breach of any of the provisions of Sections 10 through 15 of this Agreement, unless otherwise prohibited by law:

(a)Nucor shall be entitled to (i) cancel any unexercised stock options granted under any senior officer equity incentive compensation plan from and after the Effective Date (the “Post-Agreement Date Option Grants”), (ii) cease payment of any General Non-Compete Benefits, Change in Control Non-Compete Benefits and/or other similar payments (including those under the Supplemental Retirement Plan) otherwise due hereunder, (iii) seek other appropriate relief, including, without limitation, repayment by Executive of General Non-Compete Benefits, Change in Control Non-Compete Benefits and/or other similar payments (including those under the Supplemental Retirement Plan); and

(b)Executive shall (i) forfeit any (A) unexercised Post-Agreement Date Option Grants and (B) any shares of restricted stock or restricted stock units granted under any senior officer equity incentive compensation plan that vested during the 6 month period immediately preceding Executive’s termination of employment (the “Vested Stock”) and (ii) forfeit and immediately return upon demand by Nucor any profit realized by Executive from the exercise of any Post-Agreement Date Option Grants or sale or exchange of any Vested Stock during the 6 month period preceding Executive’s breach of any of the provisions of Sections 10 through 15 of this Agreement.

Executive agrees that any breach or threatened breach of any of the provisions of Sections 10 through 15 will cause Nucor irreparable harm which cannot be remedied through monetary damages and the alternative relief set forth in Sections 17(a) and (b) shall not be considered an adequate remedy for the harm Nucor would incur. Executive further agrees that such remedies in Sections 17(a) and (b) will not preclude injunctive relief.

If Executive breaches or threatens to breach any of the provisions of Sections 12, 13 or 14 of this Agreement and Nucor obtains an injunction, preliminary or otherwise, ordering Executive to adhere to the Restrictive Period required by the applicable Section, then the applicable Restrictive Period will be extended by the number of days that Nucor has alleged that Executive has been in breach of any of these provisions.

Executive further agrees, unless otherwise prohibited by law, to pay Nucor’s attorneys’ fees and costs incurred in successfully enforcing its rights pursuant to this Section 17, or in defending against any action brought by Executive or on Executive’s behalf in violation of or under this Section 17 in which Nucor prevails. Executive agrees that Nucor’s actions pursuant to this Section 17, including, without limitation, filing a legal action, are permissible and are not and will not be considered by Executive to be retaliatory. Executive further represents and acknowledges that in the event of the termination of Executive’s employment for any reason, Executive’s experience and capabilities are such that Executive can obtain employment and that enforcement of this Agreement by way of injunction will not prevent Executive from

earning a livelihood.

18.Reasonableness of Restrictions. Executive has carefully considered the nature and extent of the restrictions upon Executive and the rights and remedies conferred upon Nucor under Sections 10, 11, 12, 13, 14 and 17 and hereby acknowledges and agrees that the same are reasonable in time and territory, are designed to eliminate competition which would otherwise be unfair to Nucor, do not interfere with Executive’s exercise of Executive’s inherent skill and experience, are reasonably required to protect the legitimate interests of Nucor, and do not confer a benefit upon Nucor disproportionate to the detriment to Executive. Executive certifies that Executive has had the opportunity to discuss this Agreement with such legal advisors as Executive chooses and that Executive understands its provisions and has entered into this Agreement freely and voluntarily.

19.Applicable Law. Following Executive’s promotion to Executive Vice President of Nucor Corporation, Executive’s primary place of employment will be Nucor’s corporate headquarters located in Charlotte, North Carolina. Accordingly, this Agreement is made in, and shall be interpreted, construed and governed according to the laws of, the State of North Carolina, regardless of choice of law principles of any jurisdiction to the contrary. Each party, for themselves and their successors and assigns, hereby irrevocably (a) consents to the exclusive jurisdiction of the North Carolina state and federal courts located in Mecklenburg County, North Carolina and (b) waives any objection to any such action based on venue or forum non conveniens. Further, Executive hereby irrevocably consents to the jurisdiction of any court or similar body within the Restricted Territory for enforcement of any judgment entered in a court or similar body pursuant to this Agreement. This Agreement is intended, among other things, to supplement the provisions of the North Carolina Trade Secrets Protection Act and the Defend Trade Secrets Act of 2016, each as amended from time to time, and the duties Executive owes to Nucor under North Carolina common law, including, but not limited to, fiduciary duties owed by Executive to Nucor.

20.Executive to Return Property. Executive agrees that upon (a) the termination of Executive’s employment with Nucor and within 3 business days thereof, whether by Executive or Nucor for any reason (with or without cause), or (b) the written request of Nucor, Executive (or in the event of the death or disability of Executive, Executive’s heirs, successors, assigns and legal representatives) shall return to Nucor any and all property of Nucor regardless of the medium in which such property is stored or kept, including but not limited to all Secret Information, Confidential Information, notes, data, tapes, computers, lists, customer lists, supplier lists, vendor lists, names of customers, suppliers or vendors, reference items, phones, documents, sketches, drawings, software, product samples, rolodex cards, forms, manuals, keys, pass or access cards and equipment, without retaining any copies or summaries of such property. Executive further agrees that to the extent Secret Information or Confidential Information are in electronic format and in Executive’s possession, custody or control, Executive will provide all such copies to Nucor and will not keep copies in such format but, upon Nucor’s request, will confirm the permanent deletion or other destruction thereof.

21.Entire Agreement; Amendments. This Agreement supersedes, discharges and cancels all previous agreements regarding Executive’s employment with Nucor, including without limitation that certain Executive Agreement by and between Nucor Corporation and Executive dated as of December 21, 2017, and constitutes the entire agreement between the parties with regard to the subject matter hereof. No agreements, representations, or statements of any party not contained herein shall be binding on either party. Further, no amendment or variation of the terms or conditions of this Agreement shall be valid unless in writing and signed by both parties.

22.Assignability. This Agreement and the rights and duties created hereunder shall not be assignable or delegable by Executive. Nucor may, at its option and without consent of Executive, assign

or delegate its rights and duties hereunder, in whole or in part, to any successor entity or transferee of Nucor Corporation’s assets.

23.Binding Effect. This Agreement shall be binding upon and inure to the benefit of Nucor and Executive and their respective permitted successors, assigns, heirs and legal representatives.

24.No Waiver. No failure or delay by any party to this Agreement to enforce any right specified in this Agreement will operate as a waiver of such right, nor will any single or partial exercise of a right preclude any further or later enforcement of the right within the period of the applicable statute of limitations. No waiver of any provision hereof shall be effective unless such waiver is set forth in a written instrument executed by the party waiving compliance.

25.Cooperation. Executive agrees that both during and after Executive’s employment, Executive shall, at Nucor’s request, render all assistance and perform all lawful acts that Nucor considers necessary or advisable in connection with any litigation involving Nucor or any of its directors, officers, employees, shareholders, agents, representatives, consultants, clients, customers, suppliers or vendors. Executive understands and agrees that Nucor will reimburse Executive for any reasonable documented expense Executive incurs related to this cooperation and assistance, but will not be obligated to pay Executive any additional amounts.

26.Compliance with Code Section 409A. Notwithstanding anything in this Agreement to the contrary, if (a) Executive is a “specified employee” under Section 409A(a)(2)(B)(i) of Code as of the Date of Termination and (b) any amount or benefit that Nucor determines would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code would otherwise be payable or distributable under this Agreement by reason of Executive’s separation from service, then to the extent necessary to comply with Code Section 409A: (i) if the payment or distribution is payable in a lump sum, Executive’s right to receive payment or distribution of such non-exempt deferred compensation will be delayed until the earlier of Executive’s death or the 7^th month following the Date of Termination, and (ii) if the payment, distribution or benefit is payable or provided over time, the amount of such non-exempt deferred compensation or benefit that would otherwise be payable or provided during the 6 month period immediately following the Date of Termination will be accumulated, and Executive’s right to receive payment or distribution of such accumulated amount or benefit will be delayed until the earlier of Executive’s death or the 7^th month following the Date of Termination and paid or provided on the earlier of such dates, without interest, and the normal payment or distribution schedule for any remaining payments, distributions or benefits will commence.

For purposes of this Agreement, the term “separation from service” shall be defined as provided in Code Section 409A and applicable regulations, and Executive shall be a “specified employee” during the 12 month period beginning April 1 each year if Executive met the requirements of Section 416(i)(1)(A)(i), (ii) or (iii) of the Code (applied in accordance with the regulations thereunder and disregarding Section 416(i)(5) of the Code) at any time during the 12 month period ending on the December 31 immediately preceding the Date of Termination.
