damages award, as determined by the court, is the result of the conduct, acts or omissions of Motorola. 
 E. Conditions. The obligations set forth in
this Section 10 are contingent upon: (i) the party seeking indemnification (the indemnified Party”) giving prompt written notice to the party providing the indemnification (the “Indemnifying Party”) of any such Claim;
(ii) the Indemnified Party allowing the Indemnifying Party to have control of the defense and related settlement negotiations for the Claim; provided that the Indemnifying Party shall have no right to incur any liability on behalf of the
Indemnified Party without the Indemnified Party’s prior written consent; and (iii) the Indemnified Party fully assisting and cooperating in the defense and settlement negotiations as reasonably requested by the Indemnifying Party so long

 and 230.406 
  

	c.	Supplier shall correct Errors in the Software in accordance with Error Severity Levels specified above. In addition, at any time during the Error correction or technical support
process, Motorola may invoke the below listed escalation procedure: 

  

	 	1.	Supplier’s escalation process is to ensure that when a problem is not being resolved in a satisfactory manner, (i) both Motorola and Supplier have a common perception of
the nature and criticality of the problem, (ii) the visibility of the problem is raised within Supplier’s organization, and (iii) appropriate Supplier resources are allocated toward solving the problem. 

  

	 	2.	The following escalation process may be invoked by Motorola when an Error, defect, non-conformity or technical support issue has been reported to Supplier, the Error substantially
affects Motorola’s Customers use of the Software, and Supplier has not yet provided a patch or bypass around the Error. 

  

	 	3.	The escalation processes can be initiated by contacting the next higher management level within Supplier’s organization. Such Supplier designate will work with Motorola’s
designated contact and management to bring a satisfactory solution to the situation. The effort will be focused on developing an action plan and coordinating whatever Supplier resources are required to meet Motorola’s needs as rapidly as
possible, within the policy stated above. 

  

	 	4.	During the period of the action plan, regular status update communications will be established between Motorola’s designate and Supplier’s designate.

  

	 	5.	If an action plan cannot be agreed to, or if the action plan fails to provide a satisfactory solution within the time frame defined in the action plan, the problem will be escalated
to Supplier’s highest management level.

 13. Supplier’s Support of Changes Requested by Motorola 
 A. Upon the request of Motorola, Supplier hereby agrees to reasonably support changes to its Software, including without limitation, the drivers, to implement
hardware and firmware changes by Motorola, and changes by [...***...]. 
 14. Confidentiality 
 A. The Parties will (i) maintain the confidentiality of each other’s Confidential Information and not disclose it to any third party, except as
authorized by the original disclosing Party in writing, (ii) restrict disclosure of Confidential Information to employees and contractors who have a “need to know,” provided that the Party binds its employees, contractors, and
subcontractors by terms of nondisclosure no less restrictive than those contained here and properly informs them of the confidential status of information provided to them, and (iii) handle Confidential Information with the same degree of care
the receiving Party applies to its own confidential information, but in no event, less than reasonable care. Confidential Information is and at all times will remain the property of the disclosing Party. No use of any Confidential Information is
permitted except as expressly provided here, and no grant under any proprietary rights is hereby given or intended, including any license implied or otherwise. 
 B. Notwithstanding anything to the contrary herein, the receiving Party has no obligation to preserve the confidentiality of any Information that is (i) previously known, or received rightfully by the receiving Party without any
obligation to keep it confidential, (ii) distributed to third parties by the disclosing Party without restriction, (iii) publicly available other than by unauthorized disclosure by the receiving Party, (iv) independently developed by
the receiving Party, without use of the disclosing party’s confidential information or (v) disclosed to a governmental authority lawfully demanding Confidential Information, provided that the receiving Party provides timely prior written
notice of such demand to the disclosing Party sufficient to allow the disclosing Party a reasonable opportunity to object to the scope or terms of the governmental demand, and confidentiality is otherwise maintained by the Parties after the
disclosure. Motorola or third parties may be developing products similar in functionality to those developed by Supplier; the receipt of Confidential Information by Motorola from Supplier will not prohibit Motorola or third parties from developing
products, provided that the provisions of this Agreement regarding the protection of Confidential Information have not been breached. 
 C. The
existence of this Agreement, and its terms and conditions, are Confidential Information. 
 D. Each Party’s obligations under this Agreement to
keep confidential and restrict use of the other Party’s Confidential Information will survive five (5) years from expiration or termination of this Agreement.

the acquisition of ownership or control by a competitor of the terminating Party. 
 17. Force Majeure 
 Neither Party is liable for delays in delivery or performance caused by the following, if beyond the actual control of the delayed Party: acts of God, including
hurricanes, tornadoes, earthquakes, fires and floods; acts of terrorism; acts of civil or military authority, including war or embargoes; epidemics; and riots. If a force majeure event occurs, the date of delivery or performance will be extended for
a period equal to the time lost by the occurrence of the force majeure event. The aggrieved Party will send written notice and particulars to the other Party, prior to or at the time of the original required performance. If a force majeure event
results in a delay of more than [...***...] and delivery or performance cannot be completed within an additional [...***...], the aggrieved Party may cancel any further performance, including pending purchase orders and releases, with no
liability. 
 18. Governing Law and Dispute Resolution 
 A. This Agreement is governed by and construed in accordance with the laws of the state of New York, without regard to its conflict of law provisions. The Parties specifically disclaim application of the United Nations Convention
on Contracts for the International Sale of Goods. 
 B. Motorola and Supplier will attempt to settle any claim or controversy arising out of this
Agreement through consultation and negotiation in good faith and spirit of mutual cooperation. Disputes will be resolved by the following process. The dispute will be submitted in writing to a panel of [...***...]. If the [...***...] are
unable to resolve the dispute within [...***...], either Party may refer the dispute to mediation, the cost of which will be shared equally by the Parties, except that each Party will pay its own attorney’s fees. Within [...***...]
after written notice demanding mediation, the Parties will choose a mutually acceptable mediator. Neither Party will unreasonably withhold consent to the selection of the mediator. Mediation will be conducted in New York. If the dispute cannot be
resolved through mediation within [...***...], either Party may submit the dispute to a court of competent jurisdiction. Use of any dispute resolution procedure will not be construed under the doctrines of laches, waiver, or estoppel to
adversely affect the rights of either Party. Nothing herein prevents either Party from resorting directly to judicial proceedings if the dispute is with respect to intellectual property rights, or interim relief from a court is necessary to prevent
serious and irreparable injury to a Party or others. The Parties’ performance under this Agreement will not be suspended during the pendency of any dispute.

 20. Technology Escrow 

 A. In the event during the term of this Agreement Supplier: whether directly or through a successor or affiliate, (a) at any time ceases to
conduct its business or to offer the Products and/or Software to Motorola, or (b) files for bankruptcy, dissolution or liquidation and such filing is not dismissed or effectively revoked within ninety (90) days; and (ii) neither
Supplier nor any successor or affiliate or other third party assumes and/or duly performs Supplier’s obligations under this Agreement (together, a “Limited License Event”), Supplier hereby grants to Motorola a [...***...]
right and license (the “Limited License”), [...***...], under Supplier’s Technology (but only to the extent Supplier has the right, without further action, to grant such Limited License hereunder), to use all such
Technology as necessary to make, have made, distribute, maintain, use, market, sell and reproduce all or any portion of the Technology for the purpose of allowing Motorola to exercise its rights under this Agreement, including without limitation,
the right to continue to meet demand for the Products and to provide support for the Products and Software. In the event that Motorola exercises this Limited License and makes or has made Products, Motorola shall pay to Entropic a per unit royalty
(the “Unit Royalty”). The price of such Unit Royalty shall be determined as set for below in Section 20(E). 
 B. Promptly following
any Limited License Event, Supplier shall provide to Motorola all of Supplier’s Technology relating to the Products and Software (excluding [...***...]; provided that the escrow materials shall include a list of [...***...])
necessary for Motorola to exercise its rights under Section 20(A) or Motorola shall otherwise have the right to obtain the release of the relevant Supplier Technology from the escrow agent under the Technology Escrow Agreement described in
Section 20(D). 
 C. It is expressly agreed and acknowledged such information and materials as are provided hereunder by Supplier shall remain
the proprietary and confidential property of Supplier, the use and disclosure of which shall at all times be subject to Section 14, subject to the Limited License granted herein. 
 D. Supplier shall place into escrow with an independent third party escrow agent, [...***...], copies of such portions of Supplier’s Technology necessary to allow Motorola to fully take advantage of

or effort, including a list of [...***...], pursuant to a separate escrow agreement substantially in the form attached hereto as Exhibit G (the “Technology Escrow Agreement”). Motorola shall be permitted to access the escrowed
materials only upon the occurrence of one of the events listed in Section 20(A). The fees and expenses of the escrow agent shall be paid by [...***...]. All materials placed in escrow shall be [...***...]. Supplier agrees to use
best efforts to ensure that the Materials along with any revised or supplemented materials (excluding any documentation relating to any third party software or intellectual property) delivered pursuant to this paragraph [...***...].

 E. In the event of the occurrence of a Limited License Event, Motorola shall have the right to deliver to
Supplier Motorola’s good faith estimate of the fair price for the Unit Royalty (the “Motorola Fair Price”) and shall set forth in reasonable detail its calculation of such fair price. The Motorola Fair Price shall be calculated to
include [...***...]. Unless, within [...***...] after Supplier’s receipt of the Motorola Fair Price, Supplier delivers to Motorola a written statement of objection specifying Supplier’s good faith estimate of such fair price
(the “Supplier Fair Price”), setting forth in reasonable detail its calculation of such fair price, the Motorola Fair Price shall be the price for the Unit Royalty. If Supplier delivers the Supplier Fair Price within [...***...]
after the receipt of the Motorola Fair Price, Supplier and Motorola shall negotiate in good faith for a period of [...***...] following the delivery of the Supplier Fair Price to determine the fair price of the Unit Royalty. If Supplier and
Motorola agree on such fair price, such agreed price shall be the price for the Unit Royalty. If, at the end of such [...***...] period, Supplier and Motorola have not so determined such fair price, Supplier and Motorola shall have
[...***...] to select an independent valuation expert experienced in valuing such a royalty to determine such fair price. If the parties do not reach an agreement on the choice of such independent valuation expert during such [...***...]
period, Motorola and Supplier shall request the American Arbitration Association to select an independent valuation expert with no material relationship with Supplier or Motorola to act as such independent valuation expert. Upon such appointment,
Motorola and Supplier shall each promptly provide the expert so selected with (x) its respective proposed fair price, which may be different from the fair prices included in the Motorola Fair Price and Supplier Fair Price, (y) any
documentation each elects to deliver in order to illustrate the basis on which it determined its proposed fair price and (z) any additional information reasonably requested by such expert. Within [...***...] days after initial receipt of
the proposed values and related documentation, such expert shall make its decision as to the fair price for the Unit Royalty. The expert shall be required to select one of the two proposed valuations as the fair price or a fair price in between. The
decision of the expert shall be final and binding upon Motorola and Supplier. The expenses of the expert shall be borne [...***...]. Notwithstanding this Section E, Motorola shall have the right to exercise its Limited License during this
period. 
 F. If, at any point following the release of materials from escrow, Supplier or its successor, affiliate or other third party can
reasonably demonstrate to Motorola that such party can [...***...], then Motorola shall allow such party to [...***...] and Motorola shall immediately [...***...]. 
 21. Other Terms and Conditions 
 Assignment. Neither Party may assign this Agreement or any of its rights or
obligations hereunder, without the prior written approval of the other Party, which approval will not be unreasonably withheld. Supplier hereby authorizes Motorola to assign its rights or obligations under this Agreement without the need for further
Supplier approval, in whole or in part, in connection with the divestiture of a Motorola business unit covered by this Agreement. Motorola hereby authorizes Supplier to assign its rights or obligations under this Agreement in the event of an

 Cumulative Remedies. Except as otherwise provided, if either Party breaches this Agreement, the non-breaching Party has the right to assert all available legal and equitable remedies. 
 Disclosures. This Agreement does not grant Supplier or any third party, by implication, estoppel, or otherwise, any right to inspect or examine any of

 Entire Agreement. This Agreement, together with the attached Exhibits, and the Materials License Agreement constitute the entire understanding between the Parties concerning the subject matters hereof and
thereof and supersede all prior discussions, agreements and representations, whether oral or written, express or implied, with respect to such subject matters; except, to the extent applicable, for the MLA which is not merged herein, and which shall
continue to be in full force and effect in accordance with its terms. No alterations or modifications of this Agreement will be binding upon either Party unless made in writing and signed by an authorized representative of each Party.

 Relationship. Supplier will perform under this Agreement solely as an independent contractor and nothing in
this Agreement will be construed to be inconsistent with that relationship. Under no circumstances will any of Supplier’s personnel be considered an employee or agent of Motorola. Nothing in this Agreement grants either Party the right or
authority to make commitments of any kind for the other, implied or otherwise, without the other Party’s prior written agreement. This Agreement does not constitute, create, or in any way is interpreted as, a joint venture, partnership, or
formal business organization of any kind.

law, the unenforceable portion will not affect any other provision of this Agreement. This Agreement will be construed as if the unenforceable provision was not present, and the Parties will negotiate in good faith to replace the unenforceable
provision with an enforceable provision with effect nearest to that of the provision being replaced.

any portion of this Agreement without Motorola’s prior written consent. Supplier retains responsibility for all services subcontracted hereunder and will indemnify Motorola against any liability caused by the acts or omissions of

the context of the provision indicates that it is intended to survive. 
 Waiver. Failure of either Party to insist upon the performance of any term,
covenant, or condition in this Agreement, or to exercise any rights under this Agreement, will not be construed as a waiver or relinquishment of the future performance of any such term, covenant, or condition, or the future exercise of any such
right, and the obligation of each Party with respect to such future performance will continue in full force and effect. 
 IN WITNESS WHEREOF, the
Parties have caused this Agreement to be executed by their duly authorized representatives, as of the Effective Date.

will have the same ranking, interest rate, maturity date, redemption rights and other terms as the applicable series of Notes. Any such additional notes, together with the applicable series of Notes, will be consolidated with and constitute a single
series of Debt Securities under the Indenture. 
 Section 4. Principal and Interest Payments; Maturity Date. (a) The Notes due 2012
shall bear interest at the rate of 5.000%, the Notes due 2017 shall bear interest at the rate of 5.750% and the Notes due 2037 shall bear interest at the rate of 6.400% per annum, in each case computed based on a 360-day year consisting of

December 1, 2012, December 1, 2017 and December 1, 2037, respectively (each, a “Maturity Date”). 
 (b)
Principal of and premium, if any, and interest on the Notes initially will be payable, subject with respect to Global Notes to compliance with DTC’s customary procedures, by wire transfer of immediately available funds to the accounts specified
by the registered holder of the Notes or, if no account is specified, by mailing a check to each such holder’s registered address. The Notes will be exchangeable and transfers of the Notes will be registrable, subject to 

 
the limitations provided in the Indenture, at the principal corporate trust office of the Trustee in New York, New York. 
 (c) If any interest payment date, stated maturity date or earlier redemption date falls on a day other than a Business Day, then the required payment of
principal of and premium, if any, and interest may be made on the next succeeding Business Day, as if it were made on the date payment was due, and no interest will accrue on the amount so payable for the period from and after that interest payment
date, the stated maturity date or earlier redemption date, as the case may be. The Notes will not have the benefit of a sinking fund. 
 Section 5. Optional Redemption. (a) The Notes will be redeemable, in whole or in part at any time and from time to time, at the Company’s option, at a redemption price equal to the greater of: 
  

	 	•	 	 100% of the principal amount of the Notes to be redeemed; or 

  

	 	•	 	 the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed (not including the portion of any payments
of interest accrued to the redemption date) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate (determined on the third Business Day preceding the
redemption date), 

 plus, in each case, accrued and unpaid interest thereon to the redemption date. 
 (b) Notice of any redemption will be mailed at least 30 days but no more than 90 days before the redemption date to each holder of the Notes to be
redeemed. The notice of redemption for the Notes will state, among other things, the amount of Notes to be redeemed, the redemption date, the redemption price and the place or places that payment will be made upon presentation and surrender of Notes
to be redeemed. If the Company redeems less than all of the Notes, the Trustee will select the particular Notes to be redeemed pro rata, by lot, or by another method the Trustee deems fair and appropriate. Unless the Company defaults in payment of
the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on and after the redemption date. 
 Section 6. Change of Control Offer to Purchase. (a) If a Change of Control Triggering Event occurs, holders of Notes may require the Company to repurchase all of any part (equal to $2,000 or an integral multiple of $1,000 in
excess thereof) of their Notes at a purchase price of 101% of the principal amount, plus accrued and unpaid interest, if any, on such Notes to the date of purchase (unless a notice of redemption has been mailed within 30 days after such Change of
Control Triggering Event stating that all of the Notes will be redeemed as described above). The Company shall be required to mail to holders of the Notes a notice describing the transaction or transactions constituting the Change of Control
Triggering Event and offering to repurchase the Notes. The notice must be mailed within 30 days after any Change of Control Triggering Event, and the repurchase must occur no earlier than 30 days and no later than 60 days after the date the notice
is mailed. 

 (b) On the date specified for repurchase of the Notes, the Company shall, to the extent lawful:

 (i) accept for payment all properly tendered Notes or portions of Notes; 
 (ii) deposit with the paying agent the required payment for all properly tendered Notes or portions of Notes; and 
 (iii) deliver to the Trustee the repurchased Notes, accompanied by an Officers’ Certificate stating, among other things, the aggregate principal
amount of repurchased Notes. 
 (c) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations applicable to the repurchase of the Notes. To the extent that these requirements conflict with the provisions requiring repurchases of the Notes, the Company shall comply with such requirements instead of the
repurchase provisions and shall not be considered to have breached its obligations with respect to repurchasing the Notes. Additionally, if an Event of Default exists under the Indenture (which is unrelated to the repurchase provisions of the
Notes), including events of default arising with respect to other issues of debt securities, the Company shall not be required to repurchase the Notes notwithstanding these repurchase provisions. 
 (d) The Company shall not be required to comply with the obligations relating to repurchasing the Notes if a third party instead satisfies all such
obligations. 
 Section 7. Events of Default. With respect to the Notes only, 
 (a) Section 7.01(a) of the Original Indenture is hereby amended by replacing “ten days” with “fifteen days”; and

 (b) Section 7.01(b) of the Original Indenture is hereby amended and restated as follows: “default in the payment of the
principal of or premium, if any, on any of the debt Securities of such series, as and when the same shall become due and payable (subject to subsection (c) below) either at maturity, upon redemption, by declaration or otherwise; or”

 Section 8. Applicability of Reports by Company. For purposes of this Third Supplemental Indenture, to the extent information,
documents or reports are required to be filed with the SEC and delivered to the Trustee or the holders of the Notes, the availability of such information, documents or reports on the SEC’s Electronic Data Gathering Analysis and Retrieval
(“EDGAR”) system or the Company’s website shall be deemed to have satisfied such delivery requirements to the Trustee or the holders of the Notes, as applicable. 
 Section 9. Miscellaneous. The provisions of this Third Supplemental Indenture are intended to supplement those of the Original Indenture as in
effect immediately prior to the execution and delivery hereof. The Original Indenture shall remain in full force and effect except to the extent that the provisions of the Original Indenture are expressly modified by the terms of this Third
Supplemental Indenture. 

 Section 10. Governing Law. This Third Supplemental Indenture and the Notes shall be governed by and
construed in accordance with the laws of the State of New York without regard to principles of conflicts of laws. 
 Section 11. Trustee
Not Responsible for Recitals or Issuance of Notes. The recitals contained herein shall be taken as statements of the Company, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or
sufficiency of this Third Supplemental Indenture or of the Notes other than with respect to the Trustee’s authentication and execution. The Trustee shall not be accountable for the use or application by the Company of the Notes or the proceeds
thereof. 
 Section 12. Counterparts. This Third Supplemental Indenture may be executed in any number of counterparts, each of which
shall be deemed to be an original for all purposes; and all such counterparts shall together constitute but one and the same instrument.

 [REVERSE SIDE OF NOTE] 
 NUCOR CORPORATION 
 5.000% Notes due December 1, 2012 
 Principal and Interest. The Company will pay the principal of this Note on December 1, 2012. 
 The Company promises to pay interest on the principal amount of this Note on each Interest Payment Date indicated on the face of this Note (each an
“Interest Payment Date”), as set forth below, at the rate per annum shown above. 
 Interest will be payable semiannually in
arrears on each Interest Payment Date, commencing June 1, 2008. 
 Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from December 3, 2007; provided that, if there is no existing default in the payment of interest and if this Note is authenticated between a regular Record Date as indicated on the face
of this Note (each a “Record Date”) referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve
30-day months. 
 The Company shall pay interest on overdue principal and premium and interest on overdue installments of interest, to the
extent lawful, at the rate borne by the Notes. 
 Method of Payment. The Company will pay interest (except as provided pursuant to Article

close of business on the May 15 and November 15 next preceding the applicable Interest Payment Date), even if such Notes are cancelled after such Record Date and on or before such Interest Payment Date. On and after the redemption or
repurchase of any of the Notes by the Company, interest, if any, shall cease to accrue on the Notes, or portion thereof, subject to redemption or repurchase. With respect to the payment of principal, the Company will make payment to the Holder that
surrenders this Note to the paying agent with respect to the Notes (a “Paying Agent”) on or after December 1, 2012. 
 Principal of and premium, if any, and interest on the Notes initially will be payable, subject with respect to Global Notes in compliance with The Depository Trust Company’s (“DTC”) customary procedures, by wire transfer of
immediately available funds to the accounts specified by the registered Holder of the Notes or, if no account is specified, by mailing a check to each such Holder’s registered address. The Notes will be exchangeable and transfers of the Notes

 If any Interest Payment Date, stated maturity date or earlier redemption date falls on a Saturday, a
Sunday, or a day on which banking institutions are authorized by law to close, then the required payment of principal of and premium, if any, and interest may be made on the next succeeding day not a Saturday, a Sunday or a day on which banking
institutions are authorized by law to close, as if it were made on the date payment was due, and no interest will accrue on the amount so payable for the period from and after that interest payment date, the stated maturity date or earlier
redemption date, as the case may be. 
 All payments made in respect of the Notes are to be made in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of public and private debts. 
 Paying Agent and Registrar.

Subsidiary or any affiliate of any of them may act as Paying Agent, Registrar or co-Registrar. 
 Indenture; Limitations. The Company issued
the Notes under an Indenture dated as of January 12, 1999 (the “Original Indenture”), as supplemented by the Third Supplemental Indenture dated December 3, 2007 (the “Third Supplemental Indenture” and together with the
Original Indenture, the “Indenture”), between the Company and The Bank of New York, as trustee (the “Trustee”). Capitalized terms herein are used as defined in the Indenture unless otherwise indicated. Reference is made to the
Indenture and the Trust Indenture Act of 1939 (the “Trust Indenture Act”) for a full, complete and detailed statement of the purposes for which the Notes are issued, the terms on which the Notes are issued and the terms, provisions and
conditions governing payment of the Notes and the provisions, among others, with respect to the nature and extent of the rights, duties and obligations of the Trustee, the Paying Agent, the Registrar, the authenticating agent, Holders and the
Company. The Holder of this Note, by acceptance of this Note, is deemed to have agreed and consented to the terms and provisions of the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. 
 The Notes are general unsecured obligations of the Company. This Note is not secured by any collateral, including assets of the Company or any of its
Subsidiaries. The Third Supplemental Indenture establishes the original aggregate principal amount of the Notes at $300,000,000, all of which were issued by the Company on the Issue Date indicated on the face of this Note, and this Note shall
represent the aggregate principal amount of such outstanding Notes from time to time endorsed thereon pursuant to the Indenture. The aggregate principal amount of outstanding Notes represented hereby may from time to time by increased or decreased
by adjustments made on the records of the Trustee, as custodian for the Depositary or its nominee, as provided in the Third Supplemental Indenture. 
 Optional Redemption. The Notes will be redeemable, at the Company’s option, in whole or in part, at any time and from time to time in accordance with the provisions set forth in the Indenture at a redemption price equal to the greater
of (i) 100% of the principal amount of 

 
such Notes to be redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on such Notes to be
redeemed (not including the portion of any such payments of interest accrued to the redemption date) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate
(determined on the third Business Day preceding such redemption date), plus, in each case, accrued and unpaid interest thereon to the redemption date. 
 Change of Control Offer to Purchase. Upon a Change of Control Triggering Event, the Company shall be required to make an offer to purchase the Notes on the terms set forth in the Third Supplemental Indenture.

 Denominations; Transfer; Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000 of principal amount
and integral multiples of $1,000 in excess thereof. The transfer or exchange of Notes may be registered and the Notes may be exchanged in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes, fees and/or other governmental charges required by law or permitted by the Indenture. The Registrar need not register the transfer or exchange of any Notes selected for redemption. Also, it
need not register the transfer or exchange of any Notes for a period of 15 days before the day of the mailing of a notice of redemption of Notes selected for redemption. 
 As provided in the Indenture and subject to certain limitations therein set forth, Notes will be issued only in registered form and initially will be represented by one or more Global Notes registered in the name of a
nominee of DTC. Beneficial interests in the Notes will be shown on, and transfers thereof will be effected only through, the records maintained by DTC participants. Except for the limited circumstances described in the Indenture, owners of
beneficial interests in the Notes will not be entitled to receive definitive Notes in registered, certificated form and will not be considered the Holders thereof. 
 The Company will provide for registration of transfers of the Notes through the Registrar, subject to the operations and procedures of DTC in effect from time to time, upon receipt of the information regarding the
form of transfer and the status of the transferee to be provided on the Assignment Form attached hereto, along with such other opinions of counsel, certifications and/or other information satisfactory to the Company and the Trustee in connection
with certain transfers. 
 Persons Deemed Owners. A Holder shall be treated as the owner of a Note for all purposes. 
 Unclaimed Money. If money for the payment of principal and premium, if any, or interest remains unclaimed for one year, the Trustee or the Paying Agent
will pay the money back to the Company at its written request. After that, Holders entitled to the money must look to the Company for payment, unless applicable law designates another Person, and all liability of the Trustee and such Paying Agent
with respect to such money shall cease. 
 Defeasance and Discharge Prior to Redemption or Maturity. If the Company deposits with the
Trustee, in trust, money, U.S. Government Obligations and/or Eligible 

 
Obligations or any combination of the foregoing which through the payment of interest thereof and principal thereof in accordance with their terms will
provide money in an amount sufficient to pay the then outstanding principal of, interest, if any, and premium, if any, on the Notes (and any other Debt Securities of the same series) to redemption or maturity, and complies with certain other
provisions of the Indenture relating thereto, (i) the Company will be deemed to have paid and will be discharged from any and all obligations in respect of the Notes and (ii) certain provisions set forth in the Indenture will no longer be
in effect with respect to the Notes. In addition, the Company can obtain a Discharge (as defined in the Indenture) with respect to all the Debt Securities of a series by depositing with the Trustee, in trust, funds sufficient to pay at maturity or
upon redemption all of the Debt Securities of that series, provided that all of the Debt Securities of that series are by their terms to become due and payable within one year or are to be called for redemption within one year. 
 Amendment; Supplement; Waiver. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders
of at least a majority in aggregate principal amount of the Notes then outstanding, and, subject to Section 13 hereof, any existing default or Event of Default or compliance with any provision may be waived with the consent of the Holders of at
least a majority in principal amount of the Notes then outstanding; provided, however, that no supplemental indenture may, without the consent of the Holders of all Debt Securities of that series then outstanding (i) change the fixed maturity
(which term for these purposes does not include payments due pursuant to any sinking, purchase or analogous fund) of those Debt Securities, reduce the principal amount thereof, reduce the rate or extend the time of payment of interest thereon,
reduce any premium payable upon the redemption thereof or impair the right to institute suit for the enforcement of any such payment on or after the maturity thereof (or, in the case of redemption, on or after the redemption date without the consent
of the holder of each debt security so affected), or (ii) reduce the percentage of Debt Securities of a series required to approve any such supplemental indenture. Without notice to or the consent of any Holder, the parties thereto may amend or
supplement the Indenture or the Notes to, among other things, clarify or cure any ambiguity, defect or inconsistency and make any change that does not adversely affect the rights of any Holder in any material respect. 
 Restrictive Covenants. The Indenture imposes certain limitations on the ability of the Company and its Restricted Subsidiaries, among other things, to
(a) create, assume, issue, guarantee, or incur any Secured Indebtedness, (b) enter into any Sale and Leaseback Transaction, (c) merge into or consolidate with or convey or transfer its properties substantially as an entirety to any
person. Within 120 days after the end of the last fiscal quarter of each year, the Company shall deliver to the Trustee an Officers’ Certificate stating whether or not the signers know of any noncompliance with the terms, provisions, covenants
and conditions under the Indenture. 
 Successor Persons. When a successor person or other entity assumes all the obligations of its
predecessor under the Notes and the Indenture, as permitted by the Indenture, the predecessor person will be released from those obligations. 
 Defaults and Remedies. An Event of Default is: (a) default in the payment of any installment of interest upon the Notes (or other Debt Securities of the same series), and continuance of such default for 15 days after receipt by the
Company of written notice of such 

 
default from any Person; (b) default in the payment of the principal of or premium, if any, on the Notes (or other Debt Securities of the same series),
as the same shall become due and payable either at maturity, upon redemption, by declaration or otherwise; (c) failure by the Company to observe or perform any other covenants under the Indenture for 90 days after receipt by the Company of a
written notice by the Trustee or receipt by the Company and the Trustee of written notice by Holders of at least 25% of the aggregate principal amount of the Notes (or other Debt Securities of the same series) then outstanding; and (d) certain
events of bankruptcy, insolvency and reorganization as described in the Indenture. 
 If an Event of Default, as defined in the Indenture,
occurs and is continuing, the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding may, and the Trustee at the request of such Holders shall, declare all the Notes to be due and payable. Holders may
not enforce the Indenture or the Notes, or take any action with respect to any Event of Default under the Indenture, or to institute, appear in or defend any suit or other proceeding with respect thereto, except as provided in the Indenture. The
Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations under the Indenture, Holders of at least a majority in principal amount of the Notes then outstanding may direct in
accordance with the provisions of the Indenture the Trustee in its exercise of any trust or power, including waiver of all past defaults, rescission and annulment of a declaration of acceleration and its consequences and exercise of any right,
remedy or power available to the Trustee. 
 Prior to any declaration accelerating the maturity of the Notes, the Holders of a majority in
principal amount of the outstanding Notes may, on behalf of the Holders of the Notes, waive any past default or Event of Default with respect to the Notes except a default (i) in the payment of principal of, premium, if any, or interest, if
any, on the Notes or (ii) in regard to a covenant or provision applicable to that series that cannot be modified or amended without the consent of the Holder of each outstanding Note. After the principal of all outstanding Notes has been
declared due and payable but before any judgment or decree for the payment of the money has been obtained or entered, the Holders of a majority in principal amount of the outstanding Notes may waive all defaults with respect to the Notes and rescind
and annul that declaration if the Company has paid or deposited with the Trustee a sum sufficient to pay all matured installments of principal, premium, if any, and interest which has become due other than by acceleration, and any and all other
Events of Default with respect to the Notes have been remedied, cured or waived. 
 Trustee Dealings with Company. Except as prohibited by
the Indenture, the Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or its Affiliates and may otherwise deal with the Company or its Affiliates as if
it were not the Trustee. 
 No Recourse Against Others. No recourse for the payment of the principal of, premium, if any, or interest on the
Notes issued under the Indenture or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any of the Company’s obligations, covenants or agreements in the Indenture, or in Notes or because of the creation of
any Indebtedness represented thereby, shall be had against any of the Company’s incorporators, stockholders, officers, directors or employees or of any successor Person thereof. Each Holder, 

 
by accepting Notes issued under the Indenture, waives and releases all such liability. The waiver and release are a condition of, and part of the
consideration for the issuance of the Notes. 
 Authentication. This Note shall not be entitled to any right or benefit under the Indenture,
or be valid, or become obligatory for any purpose, until the Trustee or authenticating agent signs the certificate of authentication on the other side of this Note. 
 Governing Law. The Notes shall be governed by and construed in accordance with the laws of the State of New York without regard to principles of conflicts of laws. 
 The Company will furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to Nucor Corporation, 1915

 [REVERSE SIDE OF NOTE] 
 NUCOR CORPORATION 
 5.750% Notes due December 1, 2017 
 Principal and Interest. The Company will pay the principal of this Note on December 1, 2017. 
 The Company promises to pay interest on the principal amount of this Note on each Interest Payment Date indicated on the face of this Note (each an
“Interest Payment Date”), as set forth below, at the rate per annum shown above. 
 Interest will be payable semiannually in
arrears on each Interest Payment Date, commencing June 1, 2008. 
 Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from December 3, 2007; provided that, if there is no existing default in the payment of interest and if this Note is authenticated between a regular Record Date as indicated on the face
of this Note (each a “Record Date”) referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve
30-day months. 
 The Company shall pay interest on overdue principal and premium and interest on overdue installments of interest, to the
extent lawful, at the rate borne by the Notes. 
 Method of Payment. The Company will pay interest (except as provided pursuant to Article
Seven of the Indenture with respect to defaulted interest and interest) on the principal amount of the Notes as provided above on each June 1 and December 1 to the Persons who are Holders (as reflected in the Debt Security register at the
close of business on the May 15 and November 15 next preceding the applicable Interest Payment Date), even if such Notes are cancelled after such Record Date and on or before such Interest Payment Date. On and after the redemption or
repurchase of any of the Notes by the Company, interest, if any, shall cease to accrue on the Notes, or portion thereof, subject to redemption or repurchase. With respect to the payment of principal, the Company will make payment to the Holder that
surrenders this Note to the paying agent with respect to the Notes (a “Paying Agent”) on or after December 1, 2017. 
 Principal of and premium, if any, and interest on the Notes initially will be payable, subject with respect to Global Notes in compliance with The Depository Trust Company’s (“DTC”) customary procedures, by wire transfer of
immediately available funds to the accounts specified by the registered Holder of the Notes or, if no account is specified, by mailing a check to each such Holder’s registered address. The Notes will be exchangeable and transfers of the Notes
will be registrable, subject to the limitations provided in the Indenture (as defined below), at the principal corporate trust office of the Trustee (as defined below) in New York, New York. 

 If any Interest Payment Date, stated maturity date or earlier redemption date falls on a Saturday, a
Sunday, or a day on which banking institutions are authorized by law to close, then the required payment of principal of and premium, if any, and interest may be made on the next succeeding day not a Saturday, a Sunday or a day on which banking
institutions are authorized by law to close, as if it were made on the date payment was due, and no interest will accrue on the amount so payable for the period from and after that interest payment date, the stated maturity date or earlier
redemption date, as the case may be. 
 All payments made in respect of the Notes are to be made in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of public and private debts. 
 Paying Agent and Registrar.
Initially, the Trustee will act as authenticating agent, Paying Agent and Registrar with respect to the Notes (the “Registrar”). The Company may change any authenticating agent, Paying Agent or Registrar without notice. The Company, any
Subsidiary or any affiliate of any of them may act as Paying Agent, Registrar or co-Registrar. 
 Indenture; Limitations. The Company issued
the Notes under an Indenture dated as of January 12, 1999 (the “Original Indenture”), as supplemented by the Third Supplemental Indenture dated December 3, 2007 (the “Third Supplemental Indenture” and together with the
Original Indenture, the “Indenture”), between the Company and The Bank of New York, as trustee (the “Trustee”). Capitalized terms herein are used as defined in the Indenture unless otherwise indicated. Reference is made to the
Indenture and the Trust Indenture Act of 1939 (the “Trust Indenture Act”) for a full, complete and detailed statement of the purposes for which the Notes are issued, the terms on which the Notes are issued and the terms, provisions and
conditions governing payment of the Notes and the provisions, among others, with respect to the nature and extent of the rights, duties and obligations of the Trustee, the Paying Agent, the Registrar, the authenticating agent, Holders and the
Company. The Holder of this Note, by acceptance of this Note, is deemed to have agreed and consented to the terms and provisions of the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. 
 The Notes are general unsecured obligations of the Company. This Note is not secured by any collateral, including assets of the Company or any of its
Subsidiaries. The Third Supplemental Indenture establishes the original aggregate principal amount of the Notes at $600,000,000, all of which were issued by the Company on the Issue Date indicated on the face of this Note, and this Note shall
represent the aggregate principal amount of such outstanding Notes from time to time endorsed thereon pursuant to the Indenture. The aggregate principal amount of outstanding Notes represented hereby may from time to time by increased or decreased
by adjustments made on the records of the Trustee, as custodian for the Depositary or its nominee, as provided in the Third Supplemental Indenture. 
 Optional Redemption. The Notes will be redeemable, at the Company’s option, in whole or in part, at any time and from time to time in accordance with the provisions set forth in the Indenture at a redemption price equal to the greater
of (i) 100% of the principal amount of 

 
such Notes to be redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on such Notes to be
redeemed (not including the portion of any such payments of interest accrued to the redemption date) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate
(determined on the third Business Day preceding such redemption date), plus, in each case, accrued and unpaid interest thereon to the redemption date. 
 Change of Control Offer to Purchase. Upon a Change of Control Triggering Event, the Company shall be required to make an offer to purchase the Notes on the terms set forth in the Third Supplemental Indenture.

 Denominations; Transfer; Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000 of principal amount
and integral multiples of $1,000 in excess thereof. The transfer or exchange of Notes may be registered and the Notes may be exchanged in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes, fees and/or other governmental charges required by law or permitted by the Indenture. The Registrar need not register the transfer or exchange of any Notes selected for redemption. Also, it
need not register the transfer or exchange of any Notes for a period of 15 days before the day of the mailing of a notice of redemption of Notes selected for redemption. 
 As provided in the Indenture and subject to certain limitations therein set forth, Notes will be issued only in registered form and initially will be represented by one or more Global Notes registered in the name of a
nominee of DTC. Beneficial interests in the Notes will be shown on, and transfers thereof will be effected only through, the records maintained by DTC participants. Except for the limited circumstances described in the Indenture, owners of
beneficial interests in the Notes will not be entitled to receive definitive Notes in registered, certificated form and will not be considered the Holders thereof. 
 The Company will provide for registration of transfers of the Notes through the Registrar, subject to the operations and procedures of DTC in effect from time to time, upon receipt of the information regarding the
form of transfer and the status of the transferee to be provided on the Assignment Form attached hereto, along with such other opinions of counsel, certifications and/or other information satisfactory to the Company and the Trustee in connection
with certain transfers. 
 Persons Deemed Owners. A Holder shall be treated as the owner of a Note for all purposes. 
 Unclaimed Money. If money for the payment of principal and premium, if any, or interest remains unclaimed for one year, the Trustee or the Paying Agent
will pay the money back to the Company at its written request. After that, Holders entitled to the money must look to the Company for payment, unless applicable law designates another Person, and all liability of the Trustee and such Paying Agent
with respect to such money shall cease. 
 Defeasance and Discharge Prior to Redemption or Maturity. If the Company deposits with the
Trustee, in trust, money, U.S. Government Obligations and/or Eligible 

 
Obligations or any combination of the foregoing which through the payment of interest thereof and principal thereof in accordance with their terms will
provide money in an amount sufficient to pay the then outstanding principal of, interest, if any, and premium, if any, on the Notes (and any other Debt Securities of the same series) to redemption or maturity, and complies with certain other
provisions of the Indenture relating thereto, (i) the Company will be deemed to have paid and will be discharged from any and all obligations in respect of the Notes and (ii) certain provisions set forth in the Indenture will no longer be
in effect with respect to the Notes. In addition, the Company can obtain a Discharge (as defined in the Indenture) with respect to all the Debt Securities of a series by depositing with the Trustee, in trust, funds sufficient to pay at maturity or
upon redemption all of the Debt Securities of that series, provided that all of the Debt Securities of that series are by their terms to become due and payable within one year or are to be called for redemption within one year. 
 Amendment; Supplement; Waiver. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders
of at least a majority in aggregate principal amount of the Notes then outstanding, and, subject to Section 13 hereof, any existing default or Event of Default or compliance with any provision may be waived with the consent of the Holders of at
least a majority in principal amount of the Notes then outstanding; provided, however, that no supplemental indenture may, without the consent of the Holders of all Debt Securities of that series then outstanding (i) change the fixed maturity
(which term for these purposes does not include payments due pursuant to any sinking, purchase or analogous fund) of those Debt Securities, reduce the principal amount thereof, reduce the rate or extend the time of payment of interest thereon,
reduce any premium payable upon the redemption thereof or impair the right to institute suit for the enforcement of any such payment on or after the maturity thereof (or, in the case of redemption, on or after the redemption date without the consent
of the holder of each debt security so affected), or (ii) reduce the percentage of Debt Securities of a series required to approve any such supplemental indenture. Without notice to or the consent of any Holder, the parties thereto may amend or
supplement the Indenture or the Notes to, among other things, clarify or cure any ambiguity, defect or inconsistency and make any change that does not adversely affect the rights of any Holder in any material respect. 
 Restrictive Covenants. The Indenture imposes certain limitations on the ability of the Company and its Restricted Subsidiaries, among other things, to
(a) create, assume, issue, guarantee, or incur any Secured Indebtedness, (b) enter into any Sale and Leaseback Transaction, (c) merge into or consolidate with or convey or transfer its properties substantially as an entirety to any
person. Within 120 days after the end of the last fiscal quarter of each year, the Company shall deliver to the Trustee an Officers’ Certificate stating whether or not the signers know of any noncompliance with the terms, provisions, covenants
and conditions under the Indenture. 
 Successor Persons. When a successor person or other entity assumes all the obligations of its
predecessor under the Notes and the Indenture, as permitted by the Indenture, the predecessor person will be released from those obligations. 
 Defaults and Remedies. An Event of Default is: (a) default in the payment of any installment of interest upon the Notes (or other Debt Securities of the same series), and continuance of such default for 15 days after receipt by the
Company of written notice of such 

 
default from any Person; (b) default in the payment of the principal of or premium, if any, on the Notes (or other Debt Securities of the same series),
as the same shall become due and payable either at maturity, upon redemption, by declaration or otherwise; (c) failure by the Company to observe or perform any other covenants under the Indenture for 90 days after receipt by the Company of a
written notice by the Trustee or receipt by the Company and the Trustee of written notice by Holders of at least 25% of the aggregate principal amount of the Notes (or other Debt Securities of the same series) then outstanding; and (d) certain
events of bankruptcy, insolvency and reorganization as described in the Indenture. 
 If an Event of Default, as defined in the Indenture,
occurs and is continuing, the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding may, and the Trustee at the request of such Holders shall, declare all the Notes to be due and payable. Holders may
not enforce the Indenture or the Notes, or take any action with respect to any Event of Default under the Indenture, or to institute, appear in or defend any suit or other proceeding with respect thereto, except as provided in the Indenture. The
Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations under the Indenture, Holders of at least a majority in principal amount of the Notes then outstanding may direct in
accordance with the provisions of the Indenture the Trustee in its exercise of any trust or power, including waiver of all past defaults, rescission and annulment of a declaration of acceleration and its consequences and exercise of any right,
remedy or power available to the Trustee. 
 Prior to any declaration accelerating the maturity of the Notes, the Holders of a majority in
principal amount of the outstanding Notes may, on behalf of the Holders of the Notes, waive any past default or Event of Default with respect to the Notes except a default (i) in the payment of principal of, premium, if any, or interest, if
any, on the Notes or (ii) in regard to a covenant or provision applicable to that series that cannot be modified or amended without the consent of the Holder of each outstanding Note. After the principal of all outstanding Notes has been
declared due and payable but before any judgment or decree for the payment of the money has been obtained or entered, the Holders of a majority in principal amount of the outstanding Notes may waive all defaults with respect to the Notes and rescind
and annul that declaration if the Company has paid or deposited with the Trustee a sum sufficient to pay all matured installments of principal, premium, if any, and interest which has become due other than by acceleration, and any and all other
Events of Default with respect to the Notes have been remedied, cured or waived. 
 Trustee Dealings with Company. Except as prohibited by
the Indenture, the Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or its Affiliates and may otherwise deal with the Company or its Affiliates as if
it were not the Trustee. 
 No Recourse Against Others. No recourse for the payment of the principal of, premium, if any, or interest on the
Notes issued under the Indenture or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any of the Company’s obligations, covenants or agreements in the Indenture, or in Notes or because of the creation of
any Indebtedness represented thereby, shall be had against any of the Company’s incorporators, stockholders, officers, directors or employees or of any successor Person thereof. Each Holder, 

 
by accepting Notes issued under the Indenture, waives and releases all such liability. The waiver and release are a condition of, and part of the
consideration for the issuance of the Notes. 
 Authentication. This Note shall not be entitled to any right or benefit under the Indenture,
or be valid, or become obligatory for any purpose, until the Trustee or authenticating agent signs the certificate of authentication on the other side of this Note. 
 Governing Law. The Notes shall be governed by and construed in accordance with the laws of the State of New York without regard to principles of conflicts of laws. 
 The Company will furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to Nucor Corporation, 1915

 [REVERSE SIDE OF NOTE] 
 NUCOR CORPORATION 
 6.400% Notes due December 1, 2037 
 Principal and Interest. The Company will pay the principal of this Note on December 1, 2037. 
 The Company promises to pay interest on the principal amount of this Note on each Interest Payment Date indicated on the face of this Note (each an
“Interest Payment Date”), as set forth below, at the rate per annum shown above. 
 Interest will be payable semiannually in
arrears on each Interest Payment Date, commencing June 1, 2008. 
 Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from December 3, 2007; provided that, if there is no existing default in the payment of interest and if this Note is authenticated between a regular Record Date as indicated on the face
of this Note (each a “Record Date”) referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve
30-day months. 
 The Company shall pay interest on overdue principal and premium and interest on overdue installments of interest, to the
extent lawful, at the rate borne by the Notes. 
 Method of Payment. The Company will pay interest (except as provided pursuant to Article
Seven of the Indenture with respect to defaulted interest and interest) on the principal amount of the Notes as provided above on each June 1 and December 1 to the Persons who are Holders (as reflected in the Debt Security register at the
close of business on the May 15 and November 15 next preceding the applicable Interest Payment Date), even if such Notes are cancelled after such Record Date and on or before such Interest Payment Date. On and after the redemption or
repurchase of any of the Notes by the Company, interest, if any, shall cease to accrue on the Notes, or portion thereof, subject to redemption or repurchase. With respect to the payment of principal, the Company will make payment to the Holder that
surrenders this Note to the paying agent with respect to the Notes (a “Paying Agent”) on or after December 1, 2037. 
 Principal of and premium, if any, and interest on the Notes initially will be payable, subject with respect to Global Notes in compliance with The Depository Trust Company’s (“DTC”) customary procedures, by wire transfer of
immediately available funds to the accounts specified by the registered Holder of the Notes or, if no account is specified, by mailing a check to each such Holder’s registered address. The Notes will be exchangeable and transfers of the Notes
will be registrable, subject to the limitations provided in the Indenture (as defined below), at the principal corporate trust office of the Trustee (as defined below) in New York, New York. 

 If any Interest Payment Date, stated maturity date or earlier redemption date falls on a Saturday, a
Sunday, or a day on which banking institutions are authorized by law to close, then the required payment of principal of and premium, if any, and interest may be made on the next succeeding day not a Saturday, a Sunday or a day on which banking
institutions are authorized by law to close, as if it were made on the date payment was due, and no interest will accrue on the amount so payable for the period from and after that interest payment date, the stated maturity date or earlier
redemption date, as the case may be. 
 All payments made in respect of the Notes are to be made in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of public and private debts. 
 Paying Agent and Registrar.
Initially, the Trustee will act as authenticating agent, Paying Agent and Registrar with respect to the Notes (the “Registrar”). The Company may change any authenticating agent, Paying Agent or Registrar without notice. The Company, any
Subsidiary or any affiliate of any of them may act as Paying Agent, Registrar or co-Registrar. 
 Indenture; Limitations. The Company issued
the Notes under an Indenture dated as of January 12, 1999 (the “Original Indenture”), as supplemented by the Third Supplemental Indenture dated December 3, 2007 (the “Third Supplemental Indenture” and together with the
Original Indenture, the “Indenture”), between the Company and The Bank of New York, as trustee (the “Trustee”). Capitalized terms herein are used as defined in the Indenture unless otherwise indicated. Reference is made to the
Indenture and the Trust Indenture Act of 1939 (the “Trust Indenture Act”) for a full, complete and detailed statement of the purposes for which the Notes are issued, the terms on which the Notes are issued and the terms, provisions and
conditions governing payment of the Notes and the provisions, among others, with respect to the nature and extent of the rights, duties and obligations of the Trustee, the Paying Agent, the Registrar, the authenticating agent, Holders and the
Company. The Holder of this Note, by acceptance of this Note, is deemed to have agreed and consented to the terms and provisions of the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. 
 The Notes are general unsecured obligations of the Company. This Note is not secured by any collateral, including assets of the Company or any of its
Subsidiaries. The Third Supplemental Indenture establishes the original aggregate principal amount of the Notes at $400,000,000, all of which were issued by the Company on the Issue Date indicated on the face of this Note, and this Note shall
represent the aggregate principal amount of such outstanding Notes from time to time endorsed thereon pursuant to the Indenture. The aggregate principal amount of outstanding Notes represented hereby may from time to time by increased or decreased
by adjustments made on the records of the Trustee, as custodian for the Depositary or its nominee, as provided in the Third Supplemental Indenture. 
 Optional Redemption. The Notes will be redeemable, at the Company’s option, in whole or in part, at any time and from time to time in accordance with the provisions set forth in the Indenture at a redemption price equal to the greater
of (i) 100% of the principal amount of 

 
such Notes to be redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on such Notes to be
redeemed (not including the portion of any such payments of interest accrued to the redemption date) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate
(determined on the third Business Day preceding such redemption date), plus, in each case, accrued and unpaid interest thereon to the redemption date. 
 Change of Control Offer to Purchase. Upon a Change of Control Triggering Event, the Company shall be required to make an offer to purchase the Notes on the terms set forth in the Third Supplemental Indenture.

 Denominations; Transfer; Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000 of principal amount
and integral multiples of $1,000 in excess thereof. The transfer or exchange of Notes may be registered and the Notes may be exchanged in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes, fees and/or other governmental charges required by law or permitted by the Indenture. The Registrar need not register the transfer or exchange of any Notes selected for redemption. Also, it
need not register the transfer or exchange of any Notes for a period of 15 days before the day of the mailing of a notice of redemption of Notes selected for redemption. 
 As provided in the Indenture and subject to certain limitations therein set forth, Notes will be issued only in registered form and initially will be represented by one or more Global Notes registered in the name of a
nominee of DTC. Beneficial interests in the Notes will be shown on, and transfers thereof will be effected only through, the records maintained by DTC participants. Except for the limited circumstances described in the Indenture, owners of
beneficial interests in the Notes will not be entitled to receive definitive Notes in registered, certificated form and will not be considered the Holders thereof. 
 The Company will provide for registration of transfers of the Notes through the Registrar, subject to the operations and procedures of DTC in effect from time to time, upon receipt of the information regarding the
form of transfer and the status of the transferee to be provided on the Assignment Form attached hereto, along with such other opinions of counsel, certifications and/or other information satisfactory to the Company and the Trustee in connection
with certain transfers. 
 Persons Deemed Owners. A Holder shall be treated as the owner of a Note for all purposes. 
 Unclaimed Money. If money for the payment of principal and premium, if any, or interest remains unclaimed for one year, the Trustee or the Paying Agent
will pay the money back to the Company at its written request. After that, Holders entitled to the money must look to the Company for payment, unless applicable law designates another Person, and all liability of the Trustee and such Paying Agent
with respect to such money shall cease. 
 Defeasance and Discharge Prior to Redemption or Maturity. If the Company deposits with the
Trustee, in trust, money, U.S. Government Obligations and/or Eligible 

 
Obligations or any combination of the foregoing which through the payment of interest thereof and principal thereof in accordance with their terms will
provide money in an amount sufficient to pay the then outstanding principal of, interest, if any, and premium, if any, on the Notes (and any other Debt Securities of the same series) to redemption or maturity, and complies with certain other
provisions of the Indenture relating thereto, (i) the Company will be deemed to have paid and will be discharged from any and all obligations in respect of the Notes and (ii) certain provisions set forth in the Indenture will no longer be
in effect with respect to the Notes. In addition, the Company can obtain a Discharge (as defined in the Indenture) with respect to all the Debt Securities of a series by depositing with the Trustee, in trust, funds sufficient to pay at maturity or
upon redemption all of the Debt Securities of that series, provided that all of the Debt Securities of that series are by their terms to become due and payable within one year or are to be called for redemption within one year. 
 Amendment; Supplement; Waiver. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders
of at least a majority in aggregate principal amount of the Notes then outstanding, and, subject to Section 13 hereof, any existing default or Event of Default or compliance with any provision may be waived with the consent of the Holders of at
least a majority in principal amount of the Notes then outstanding; provided, however, that no supplemental indenture may, without the consent of the Holders of all Debt Securities of that series then outstanding (i) change the fixed maturity
(which term for these purposes does not include payments due pursuant to any sinking, purchase or analogous fund) of those Debt Securities, reduce the principal amount thereof, reduce the rate or extend the time of payment of interest thereon,
reduce any premium payable upon the redemption thereof or impair the right to institute suit for the enforcement of any such payment on or after the maturity thereof (or, in the case of redemption, on or after the redemption date without the consent
of the holder of each debt security so affected), or (ii) reduce the percentage of Debt Securities of a series required to approve any such supplemental indenture. Without notice to or the consent of any Holder, the parties thereto may amend or
supplement the Indenture or the Notes to, among other things, clarify or cure any ambiguity, defect or inconsistency and make any change that does not adversely affect the rights of any Holder in any material respect. 
 Restrictive Covenants. The Indenture imposes certain limitations on the ability of the Company and its Restricted Subsidiaries, among other things, to
(a) create, assume, issue, guarantee, or incur any Secured Indebtedness, (b) enter into any Sale and Leaseback Transaction, (c) merge into or consolidate with or convey or transfer its properties substantially as an entirety to any
person. Within 120 days after the end of the last fiscal quarter of each year, the Company shall deliver to the Trustee an Officers’ Certificate stating whether or not the signers know of any noncompliance with the terms, provisions, covenants
and conditions under the Indenture. 
 Successor Persons. When a successor person or other entity assumes all the obligations of its
predecessor under the Notes and the Indenture, as permitted by the Indenture, the predecessor person will be released from those obligations. 
 Defaults and Remedies. An Event of Default is: (a) default in the payment of any installment of interest upon the Notes (or other Debt Securities of the same series), and continuance of such default for 15 days after receipt by the
Company of written notice of such 

 
default from any Person; (b) default in the payment of the principal of or premium, if any, on the Notes (or other Debt Securities of the same series),
as the same shall become due and payable either at maturity, upon redemption, by declaration or otherwise; (c) failure by the Company to observe or perform any other covenants under the Indenture for 90 days after receipt by the Company of a
written notice by the Trustee or receipt by the Company and the Trustee of written notice by Holders of at least 25% of the aggregate principal amount of the Notes (or other Debt Securities of the same series) then outstanding; and (d) certain
events of bankruptcy, insolvency and reorganization as described in the Indenture. 
 If an Event of Default, as defined in the Indenture,
occurs and is continuing, the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding may, and the Trustee at the request of such Holders shall, declare all the Notes to be due and payable. Holders may
not enforce the Indenture or the Notes, or take any action with respect to any Event of Default under the Indenture, or to institute, appear in or defend any suit or other proceeding with respect thereto, except as provided in the Indenture. The
Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations under the Indenture, Holders of at least a majority in principal amount of the Notes then outstanding may direct in
accordance with the provisions of the Indenture the Trustee in its exercise of any trust or power, including waiver of all past defaults, rescission and annulment of a declaration of acceleration and its consequences and exercise of any right,
remedy or power available to the Trustee. 
 Prior to any declaration accelerating the maturity of the Notes, the Holders of a majority in
principal amount of the outstanding Notes may, on behalf of the Holders of the Notes, waive any past default or Event of Default with respect to the Notes except a default (i) in the payment of principal of, premium, if any, or interest, if
any, on the Notes or (ii) in regard to a covenant or provision applicable to that series that cannot be modified or amended without the consent of the Holder of each outstanding Note. After the principal of all outstanding Notes has been
declared due and payable but before any judgment or decree for the payment of the money has been obtained or entered, the Holders of a majority in principal amount of the outstanding Notes may waive all defaults with respect to the Notes and rescind
and annul that declaration if the Company has paid or deposited with the Trustee a sum sufficient to pay all matured installments of principal, premium, if any, and interest which has become due other than by acceleration, and any and all other
Events of Default with respect to the Notes have been remedied, cured or waived. 
 Trustee Dealings with Company. Except as prohibited by
the Indenture, the Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or its Affiliates and may otherwise deal with the Company or its Affiliates as if
it were not the Trustee. 
 No Recourse Against Others. No recourse for the payment of the principal of, premium, if any, or interest on the
Notes issued under the Indenture or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any of the Company’s obligations, covenants or agreements in the Indenture, or in Notes or because of the creation of
any Indebtedness represented thereby, shall be had against any of the Company’s incorporators, stockholders, officers, directors or employees or of any successor Person thereof. Each Holder, 

 
by accepting Notes issued under the Indenture, waives and releases all such liability. The waiver and release are a condition of, and part of the
consideration for the issuance of the Notes. 
 Authentication. This Note shall not be entitled to any right or benefit under the Indenture,
or be valid, or become obligatory for any purpose, until the Trustee or authenticating agent signs the certificate of authentication on the other side of this Note. 
 Governing Law. The Notes shall be governed by and construed in accordance with the laws of the State of New York without regard to principles of conflicts of laws. 
 The Company will furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to Nucor Corporation, 1915
