Nucor Corporation, a Delaware corporation (the “Company”), confirms its agreement with Banc of America Securities LLC (“Banc of America”), Citigroup Global Markets Inc. (“Citi”) and X.X. Xxxxxx Securities Inc. (“X.X. Xxxxxx” and together with Banc of America, Citi and each of the other Underwriters named in Schedule A hereto, collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom Banc of America, Citi and X.X. Xxxxxx are acting as representatives (in such capacity, the “Representatives” or “you”) with respect to the sale by the Company and purchase by the Underwriters, acting severally and not jointly, of the respective number of shares of Common Stock, par value $0.40 per share, of the Company (the “Common Stock”) set forth opposite the name of such Underwriter on Schedule A, and with respect to the grant by the Company to the Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of 3,750,000 additional shares of Common Stock to cover overallotments, if any. The 25,000,000 aggregate shares of Common Stock set forth on Schedule A (the “Initial Securities”) to be purchased by the Underwriters and all or any part of the 3,750,000 shares of Common Stock subject to the option described in Section 2(b) hereof (the “Option Securities”) are hereinafter called, collectively, the “Securities.”

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (Registration No. 333-147657), including the related base prospectus, which registration statement became effective upon filing under Rule 462(e) of the rules and regulations of the Commission (the “1933 Act Regulations”) under the Securities Act of 1933, as amended (the “1933 Act”). Such registration statement covers, among other securities, the registration of the Securities under the 1933 Act. Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus in accordance with the provisions of paragraph (b) of Rule 424 (“Rule 424(b)”) of the 1933 Act Regulations. Any information included in such prospectus that was omitted from such registration statement at the time it became effective but that is deemed to be part of and included in such registration statement pursuant to Rule 430B of the 1933 Act Regulations (“Rule 430B”) is referred to as “Rule 430B Information.” The prospectus dated November 28, 2007 (the “Base Prospectus”) together with the preliminary prospectus supplement dated May 19, 2008 used in connection with the offering of the Securities, including the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, is herein called the “Preliminary Prospectus.” Such registration statement, at any given time, including the amendments thereto to such time, the exhibits and any schedules thereto at such time, the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act at such time and the documents otherwise deemed to be a part thereof or included therein by 1933 Act Regulations at such time, is herein called the “Registration Statement.” The Registration Statement at the time it originally became effective is herein called the “Original Registration Statement.” The Base Prospectus together with the final prospectus supplement dated May 22, 2008 in the form first furnished to the Underwriters for use in connection with the offering of the Securities, including the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, is herein called the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, the Preliminary Prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“XXXXX”).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement, the Preliminary Prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in or otherwise deemed by 1933 Act Regulations to be part of or included in the Registration Statement, the Preliminary Prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, the Preliminary Prospectus or the Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934 (the “1934 Act”) which is incorporated by reference in the Registration Statement, the Preliminary Prospectus or the Prospectus, as the case may be.

Section 1. Representations and Warranties.

(a) Representations and Warranties of the Company. The Company represents and warrants to and agrees with each of the Underwriters as of the Applicable Time referred to in Section 1(a) hereof and as of the Closing Time referred to in Section 2(b) hereof, that:

(i) Status as a Well-Known Seasoned Issuer. (A) At the time of filing the Original Registration Statement, (B) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the 1933 Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the 1934 Act or form of prospectus), (C) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c) of the 1933 Act Regulations) made any offer relating to the Securities in reliance on the exemption of Rule 163 of the 1933 Act Regulations and (D) at the date hereof, the Company was and is a “well-known seasoned issuer” as defined in Rule 405 of the 1933 Act Regulations (“Rule 405”). The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405, and the Securities, since their registration on the Registration Statement, have been and remain eligible for registration by the Company on a Rule 405 “automatic shelf registration statement”. The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) of the 1933 Act Regulations objecting to the use of the automatic shelf registration statement form.

At the time of filing the Original Registration Statement, at the earliest time thereafter that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the 1933 Act Regulations) of the Securities and at the date hereof, the Company was not and is not an “ineligible issuer,” as defined in Rule 405.

(ii) Registration Statement, Prospectus and Disclosure at Time of Sale. The Original Registration Statement became effective upon filing under Rule 462(e) of the 1933 Act Regulations (“Rule 462(e)”) on November 28, 2007. No stop order suspending the effectiveness of the Registration Statement nor any notice objecting to its use has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, have been threatened by the Commission, and any request on the part of the Commission for additional information has been complied with.

To the extent that any offer that is a written communication relating to the Securities was made prior to the filing of the Original Registration Statement by the Company or any person acting on its behalf (within the meaning, for this paragraph only, of Rule 163(c) of the 1933 Act Regulations), such communication has been filed with the Commission in accordance with the exemption provided by Rule 163 of the 1933 Act Regulations (“Rule 163”) and otherwise complied with the requirements of Rule 163, including without limitation the legending requirement, to qualify such offer for the exemption from Section 5(c) of the 1933 Act provided by Rule 163.

At the respective times the Original Registration Statement and each amendment thereto became effective, at each deemed effective date with respect to the offering of the Securities, as determined for the Underwriters pursuant to Rule 430B(f)(2) of the 1933 Act Regulations, and at the Closing Time (and, if any Option Securities are purchased, at the Date of Delivery), the Registration Statement complied and will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations, and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

Neither the Prospectus nor any amendments or supplements thereto, at their respective dates and at the Closing Time (and, if any Option Securities are purchased, at the Date of Delivery) included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

The Preliminary Prospectus and the Prospectus complied when so filed in all material respects with the 1933 Act Regulations and the Preliminary Prospectus and the Prospectus delivered to the Underwriters for use in connection with this offering was identical to the electronically transmitted copies thereof filed with the Commission pursuant to XXXXX, except to the extent permitted by Regulation S-T.

As of the Applicable Time, (i) the Disclosure Package and (ii) each electronic road show, approved by the Company, when taken together as a whole with the Disclosure Package, did not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

As used in this subsection and elsewhere in this Agreement:

“Applicable Time” means 5:30 p.m. (Eastern time) on May 22, 2008 or such other time as agreed by the Company and the Underwriters.

“Disclosure Package” shall mean (i) the Base Prospectus, (ii) the Preliminary Prospectus used most recently prior to the Execution Time, (iii) the Issuer Free Writing Prospectuses, if any, identified in Schedule C hereto, (iv) any other Free Writing Prospectus that the parties hereto shall hereafter expressly agree in writing to treat as part of the Disclosure Package and (v) the final pricing terms set forth in item 1 of Schedule B.

“Free Writing Prospectus” shall mean a free writing prospectus, as defined in Rule 405.

“Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433 of the 1933 Act Regulations (“Rule 433”).

Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Securities or until any earlier date that the Company notified or notifies the Representatives as described in Section 3(c), did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, including any document incorporated by reference therein and any preliminary or other prospectus deemed to be a part thereof that has not been superseded or modified.

The representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein.

(iii) Incorporated Documents. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Prospectus on or prior to the Closing Date, at the time they were filed with the Commission, complied and will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations or the 1934 Act, and the rules and regulations of the Commission thereunder (the “1934 Act Regulations”), as applicable, and, when read together with the other information included in the Preliminary Prospectus and the Prospectus, did not and will not contain an untrue statement of a material fact or did not and will not omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

(iv) Independent Registered Public Accounting Firm. PricewaterhouseCoopers LLP, who has certified the audited financial statements, the notes related thereto and schedules included or incorporated by reference in the Registration Statement, are an independent registered public accounting firm with respect to the Company as required by the 1933 Act and the 1933 Act Regulations.

The financial statements included in or incorporated by reference into the Registration Statement, the Disclosure Package and the Prospectus, together with the related schedules and notes, present fairly, in all material respects, the consolidated financial position of the Company and its consolidated subsidiaries as of the dates indicated and the results of operations and the cash flows of the Company and its consolidated subsidiaries for the periods specified. Such financial statements have been prepared in conformity with generally accepted accounting principles in the United States (“GAAP”) applied on a consistent basis throughout the periods involved. The financial statement schedules, if any, included in the Registration Statement present fairly, in all material respects, in accordance with GAAP the information required to be stated therein.

(viii) Good Standing of the Company. The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware with corporate power and authority under such laws to own, lease and operate its properties and conduct its business as described in the Disclosure Package and the Prospectus and to enter into and perform its obligations under this Agreement; and the Company is authorized or qualified to transact business as a foreign corporation in each other jurisdiction in which it owns or leases property of a nature, or transacts business of a type, that would make such authorization or qualification necessary, except to the extent that such failure would not have a Material Adverse Effect.

(ix) Good Standing of Significant Subsidiary. Nucor-Yamato Steel Company (Limited Partnership), a Delaware limited partnership (the “Significant Subsidiary” as such term is defined in Rule 1-02 under Regulation S-X), is a limited partnership duly organized, validly existing and in good standing under the laws of the State of Delaware with partnership power and authority under such laws to own, lease and operate its properties and conduct its business; and the Significant Subsidiary is authorized or qualified to transact business as a foreign entity in each jurisdiction in which it owns or leases property of a nature, or transacts business of a type, that would make such authorization or qualification necessary, except to the extent that such failure would not have a Material Adverse Effect.

Neither the Company nor the Significant Subsidiary is in violation of its charter or by-laws or in default in the performance or observance of any material obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, loan agreement, note, lease or other agreement or instrument to which it is a party or by which it may be bound or to which any of its properties may be subject, except for such defaults that would not individually or in the aggregate result in a Material Adverse Effect. The execution, delivery and performance of this Agreement by the Company, the issuance and delivery of the Securities, the consummation by the Company of the transactions contemplated in this Agreement, in the Prospectus and in the Registration Statement and compliance by the Company with the terms of this Agreement, have been duly authorized by all necessary corporate action on the part of the Company and do not and will not result in any violation of the charter or by-laws of the Company, and do not and will not conflict with, or result in a breach of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company under (A) any contract, indenture, mortgage, loan agreement, note, lease or other agreement or instrument to which the Company is a party or by which it may be bound or to which any of its properties may be subject or (B) any existing applicable law, rule, regulation, judgment, order or decree of any government, governmental instrumentality or court, domestic or foreign, having jurisdiction over the Company or any of their respective properties (except for, in each case, such violations, conflicts, breaches or defaults or liens, charges or encumbrances that would not individually or in the aggregate have a Material Adverse Effect).

(xiii) Absence of Further Requirements. No filing with, or authorization, approval, consent, license, registration, qualification or decree of any government, governmental instrumentality or court, (other than under those required and obtained under the 1933 Act and the securities or blue sky laws of the various states), is necessary or required for the performance by the Company of its obligations hereunder, in connection with the offering, the issuance or sale of the Securities hereunder or the consummation of the transactions contemplated by this Agreement or for the due execution, delivery or performance of this Agreement by the Company, except such as have been already obtained or as may be required under the 1933 Act or the 1933 Act Regulations or state securities laws.

(xiv) Absence of Proceedings. Except as disclosed in the Disclosure Package and the Prospectus, there is no action, suit or proceeding before or by any government, governmental instrumentality or court, domestic or foreign, now pending or, to the knowledge of the Company, threatened against or affecting the Company or any subsidiary that the Company reasonably believes would individually or in the aggregate result in a Material Adverse Effect, or that would materially adversely affect the consummation of the transactions contemplated in this Agreement. There are no pending legal or governmental proceedings that are required under the 1933 Act to be described in the Registration Statement, the Disclosure Package or the Prospectus that are not so described in the Registration Statement, the Disclosure Package and the Prospectus.

(xv) Accuracy of Exhibits. There are no contracts or documents which are required to be described in the Registration Statement, the Disclosure Package, the Prospectus or the documents incorporated by reference therein or to be filed as exhibits thereto that are not described and filed as required.

(xvi) Insurance. The Company and each of its subsidiaries are insured by insurers of nationally recognized financial responsibility against such losses and risks and in such amounts as are prudent in the businesses in which they are engaged; and neither the Company nor any of its subsidiaries has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage at a cost that would not have a Material Adverse Effect.

(xvii) Possession of Licenses and Permits. The Company and the Significant Subsidiary each has all governmental licenses, permits, certificates, consents, exemptions, franchises, orders, approvals and other authorizations (collectively, “Governmental Licenses”) issued by the appropriate federal, state, local or foreign regulatory agencies or bodies necessary to own or lease, as the case may be, and to operate its properties and to carry on its business as presently conducted, except where failure to own or possess such Governmental Licenses would not have a Material Adverse Effect); all of the Governmental Licenses are valid and in full force and effect, except when the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not, individually or in the aggregate, result in a Material Adverse Effect; and neither the Company nor the Significant Subsidiary has received any notice of proceedings relating to revocation of any such Governmental Licenses, except where such revocation would not have a Material Adverse Effect.

(xviii) Possession of Intellectual Property. The Company and the Significant Subsidiary each owns or possesses, or can acquire on reasonable terms, adequate patents, patent licenses, inventions and know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures) trademarks, service marks, trade names or other intellectual property (collectively, “Intellectual Property”) necessary to carry on its business in all material respects as presently conducted, and neither the Company nor the Significant Subsidiary has received any notice of infringement of or conflict with asserted rights of others with respect to any Intellectual Property which would render any Intellectual Property invalid or inadequate to protect the interest of the Company or any of its subsidiaries therein, and which infringement or conflict (if the subject of any unfavorable decision, ruling or finding) or invalidity or inadequacy, individually or in the aggregate, would result in a Material Adverse Effect.

(xix) Absence of Labor Dispute. There are no existing, or to the knowledge of the Company, imminent labor disputes or disturbances with employees of the Company or the Significant Subsidiary which the Company reasonably believes would individually or in the aggregate, have a Material Adverse Effect.

(xx) Absence of Market Stabilization. Prior to the date hereof, neither the Company nor any of its affiliates has taken, directly or indirectly, any action which is designed to or which has constituted or which would reasonably be expected to cause or result in stabilization or manipulation of the price of the Securities in connection with the offering.

(xxi) Environmental Laws. Neither the Company nor any of its subsidiaries has violated in any material respect any foreign, federal, state or local law or regulation relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants (“Environmental Laws”), any provisions of the Employee Retirement Income Security Act of 1974, as amended, or any provisions of the Foreign Corrupt Practices Act or the rules and regulations promulgated thereunder, except for such violations which, individually or in the aggregate, would not have a Material Adverse Effect.

In the ordinary course of business, the Company and its subsidiaries conduct periodic reviews of the effect of Environmental Laws on their assets and operations, and, on the basis of such reviews, the Company has concluded that there are no costs or liabilities associated with Environmental Laws (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permits, licenses, consents, authorizations or other approvals, any related constraints on operating activities and any potential liabilities to third parties) in excess of reserves that have been established which would, individually or in the aggregate, have a Material Adverse Effect.

There is no pending claim, cause of action or written notice from any person or entity alleging potential liability (including, without limitation, alleged or potential liability or investigatory costs, cleanup costs, governmental response costs, natural resource damages, property damages, personal injuries or penalties) of the Company or any of its subsidiaries arising out of, based on or resulting from (A) the presence or release into the environment of any Hazardous Material (as defined below in this paragraph) at any location, whether or not owned by the Company or any of its subsidiaries, as the case may be, or (B) any violation of any Environmental Law, which, in either case, would, individually or in the aggregate, have a Material Adverse Effect. The term “Hazardous Material” means (i) any “hazardous substance” as defined by the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, (ii) any “hazardous waste” as defined by the Resource Conservation and Recovery Act, as amended, (iii) any petroleum or petroleum product, (iv) any polychlorinated biphenyl, and (v) any pollutant or contaminant or hazardous dangerous or toxic chemical, material, waste or substance regulated under or within the meaning of any other law relating to protection of human health or the environment or imposing liability or standards of conduct concerning any such chemical material, waste or substance.

(xxii) Accounting Controls and Disclosure Controls. Each of the Company and the Significant Subsidiary maintains a system of internal accounting controls sufficient to provide reasonable assurance that (1) transactions are executed in accordance with management’s general or specific authorization; (2) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain accountability for assets; (3) access to assets is permitted only in accordance with management’s general or specific authorization; and (4) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Except as described in the Preliminary Prospectus and the Prospectus, since the end of the Company’s most recent audited fiscal year, there has been (i) no material weakness in the Company’s internal control over financial reporting (whether or not remediated) and (ii) no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

The Company and its consolidated subsidiaries employ disclosure controls and procedures that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the 1934 Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms, and is accumulated and communicated to the Company’s management, including its principal executive officer or officers and principal financial officer or officers, as appropriate, to allow timely decisions regarding disclosure.

(xxiii) Compliance with the Xxxxxxxx-Xxxxx Act. The Company is in compliance, in all material respects, with the applicable provisions of The Xxxxxxxx-Xxxxx Act of 2002.

The Company has an authorized capitalization as set forth in the Prospectus, and all of the issued shares of capital stock of the Company have been duly and validly authorized and issued and are fully paid and non-assessable; and all of the outstanding partnership interests of the Significant Subsidiary owned indirectly by the Company have been duly authorized and validly issued and are fully paid and non-assessable and are indirectly owned by the Company, free and clear of any pledge, lien, security interest, charge, claim or encumbrance of any kind.

(xxv) Title to Property. The Company and its subsidiaries have good and marketable title in fee simple to all real property which they own and good title to all personal property owned by them, in each case free and clear of all liens, encumbrances and defects except as would not individually or in the aggregate have a Material Adverse Effect; and any real property and buildings held under lease by the Company and its subsidiaries are held by them under valid and enforceable leases except as would not individually or in the aggregate have a Material Adverse Effect.

(xxvi) No Unlawful Payments. The Company and all of its subsidiaries are in compliance, in all material respects with the provisions of the Foreign Corrupt Practices Act of 1977, and to the best of the knowledge of the Company, neither the Company nor any of its subsidiaries nor any director, officer, or employee of the Company or any of its subsidiaries has used any corporate funds for any unlawful contribution, gift, or entertainment relating to political activity.

(xxvii) Compliance with Money Laundering Act. The operations of the Company and its subsidiaries are and have been conducted at all times in compliance in all material respects with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, and the rules and regulations promulgated thereunder (the “Money Laundering Act”) and no action, suit or proceeding by or before any court or governmental agency, authority or body involving the Company or any of its subsidiaries with respect to the Money Laundering Act is pending.

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, provided that (subject to Section 6(d) hereof) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever (including the fees and disbursements of counsel chosen by you), as reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under subparagraph (i) or (ii) above;

provided, however, that this indemnity agreement does not apply to any loss, liability, claim, damage or expense to the extent arising out of an untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430B Information, the Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto).

(b) Indemnification of the Company, Directors and Officers. Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity agreement contained in Section 6(a) hereof, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (including any amendment thereto), including the Rule 430B Information, any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with information furnished in writing to the Company by such Underwriter through you expressly for use therein.

(c) Actions Against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) hereof, counsel to the indemnified parties shall be selected by the Representatives and, in the case of parties indemnified pursuant to Section 6(b) hereof, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action and, at its option, may assume the defense thereof, with counsel reasonably satisfactory to the indemnified party, provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party.

No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement Without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) hereof effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. The indemnified party shall promptly reimburse the indemnifying party for all amounts advanced to it pursuant to this Section 6(d) hereof (unless it is entitled to such amounts under Section 7 hereof) if it shall be finally judicially determined that such indemnified party was not entitled to indemnification hereunder and such loss, liability, claim, damage or expense arose out of (i) an untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by the indemnified party expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430B Information or any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) or (ii) a fraudulent misrepresentation (within the meaning of Section 11 of the 0000 Xxx) by the indemnified party.

Section 7. Contribution

If the indemnification provided for in Section 6 hereof is for any reason held to be unavailable or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discount and commission received by the Underwriters, in each case as set forth on the cover of or in the Prospectus bear to the aggregate initial public offering price of the Securities as set forth on such cover.

The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 0000 Xxx) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each director, officer and employee of the Underwriters shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the aggregate principal amount of Securities set forth opposite their respective names in Schedule A hereto and not joint.

Section 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties, indemnities, agreements and other statements of the Company or its officers and of the Underwriters set forth in or made pursuant to this Agreement will remain operative and in full force and effect regardless of any investigation made by or on behalf of the Company, any Underwriter or any person who controls the Company or any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and will survive delivery of and payment for the Securities.

Section 9. Termination of Agreement.

(a) Termination Generally. You may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Disclosure Package, any material adverse change in the business, operations, financial condition or business prospects of the Company and its subsidiaries, considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities involving the United States or escalation thereof or other calamity or crisis or any change in national or international political, financial or economic conditions, in each case the effect is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Securities or enforce contracts for the sale of the Securities or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the Financial Industry Regulatory Authority or if trading generally on the New York Stock Exchange has been materially suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices for securities have been required, by the New York Stock Exchange or by order of the Commission, the Financial Industry Regulatory Authority or any other governmental authority, (iv) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or (v) if a banking moratorium has been declared by either federal, New York or North Carolina authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party, except to the extent provided in Section 4. Notwithstanding any such termination, the provisions of Sections 1, 6, 7, 8 and 17 shall survive such termination and remain in full force and effect.

Section 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time to purchase the Initial Securities that it or they are obligated to purchase pursuant to this Agreement (the “Defaulted Securities”), you shall have the right, within 36 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms set forth in this Agreement; if, however, the non-defaulting Underwriters have not completed such arrangements within such 36-hour period, then:

(a) if the aggregate number of Defaulted Securities does not exceed 10% of the aggregate number of Initial Securities to be purchased pursuant to this Agreement, each non-defaulting Underwriter shall be obligated, each severally and not jointly, to purchase the full amount thereof in the proportions that their respective Securities underwriting obligation proportions bear to the underwriting obligations of all non-defaulting Underwriters; or

(b) if the number of Defaulted Securities exceeds 10% of the number of Initial Securities to be purchased on such date, this Agreement shall terminate without liability on the part of the Company or any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Company to sell the relevant Option Securities, as the case may be, either the (i) Representatives or (ii) the Company shall have the right to postpone the Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

Section 11. Notices. All notices and other communications under this Agreement shall be in writing and shall be deemed to have been duly given if delivered, mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters and the Company shall be directed to the addresses specified below.

As Representatives of the several Underwriters

Re:

Proposed Public Offering by Nucor Corporation

Dear Sirs:

The undersigned, a stockholder and an executive officer and/or director of Nucor Corporation, a Delaware corporation (the “Company”), understands that the Representatives propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Company providing for the public offering of shares (the “Securities”) of the Company’s common stock, par value $0.40 per share (the “Common Stock”). In recognition of the benefit that such an offering will confer upon the undersigned as a stockholder and an executive officer and/or director of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each underwriter to be named in the Underwriting Agreement that, as of the date hereof and during a period of 90 days from the date of the Underwriting Agreement, the undersigned will not, without the prior written consent of the Representatives, directly or indirectly, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any shares of the Common Stock or any securities convertible into or exchangeable or exercisable for Common Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition, or, with respect to the Company, file, or cause to be filed, any registration statement under the Securities Act of 1933, as amended, with respect to any of the foregoing (collectively, the “Lock-Up Securities”) or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether any such swap or transaction is to be settled by delivery of Common Stock or other securities, in cash or otherwise. The foregoing restrictions do not apply to (1) shares of Common Stock issued upon the exercise of an option or the conversion of a security outstanding as of the date hereof; (2) sales transactions of Common Stock described in (i) or (ii) above by our directors and executive officers of up to an aggregate of 150,000 shares of Common Stock; (3) shares of Common Stock involved in the net share settlement of restricted stock units held by executive officers or directors that vest during the 90-day lock-up period to satisfy such person’s withholding tax obligation upon such vesting; or (4) the entering into any written trading plan or agreement designed to comply with Rule 10b5-1(c)(1) promulgated pursuant to the Exchange Act of 1934, as amended, to sell shares after the 90-day lock-up period.

Notwithstanding the foregoing, and subject to the conditions below, the undersigned may also transfer the Lock-Up Securities without the prior written consent of the Representatives:

(i)

as a bona fide gift or gifts; or

(ii)

to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned (for purposes of this lock-up agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin); or

(iii)

as a distribution to limited partners, stockholders or members of the undersigned; or

(iv)

by will or intestate succession; or

(v)

to the undersigned’s affiliates or to any investment fund or other entity controlled or managed by the undersigned.

provided that (1) the Representatives receive a signed lock-up agreement for the balance of the lockup period from each donee, trustee, distributee, or transferee, as the case may be, or (2) any such transfer shall not involve a disposition for value.

Notwithstanding the foregoing, if:

(1) during the last 17 days of the 90-day lock-up period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or

(2) prior to the expiration of the 90-day lock-up period, the Company announces that it will release earnings results or becomes aware that material news or a material event will occur during the 16-day period beginning on the last day of the 90-day lock-up period, the restrictions imposed by this lock-up agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, as applicable, unless the Representatives waive, in writing, such extension.

The undersigned hereby acknowledges and agrees that written notice of any extension of the 90-day lock-up period pursuant to the previous paragraph will be delivered by the Representatives to the Company (in accordance with Section 12 of the Underwriting Agreement) and that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned. The undersigned further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this lock-up agreement during the period from the date of this lock-up agreement to and including the 34^th day following the expiration of the initial 90-day lock-up period, it will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the 90-day lock-up period (as may have been extended pursuant to the previous paragraph) has expired.

Notwithstanding anything to the contrary contained herein, in the event that the Underwriting Agreement is not signed within 30 days of the date of this Agreement, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Securities to be sold thereunder, the undersigned shall be released from all obligations hereunder and the terms of this Agreement shall be of no further force and effect.

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the Lock-Up Securities except in compliance with the foregoing restrictions.

Very truly yours,
