In the case of any lease which is terminable by the lessee upon the payment of a penalty, such net amount will be the lesser of the net amount determined assuming termination upon the first date such lease may be terminated (in which case the net amount will also include the amount of the penalty, but no rent will be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated) or the net amount determined assuming no such termination.

(d) the adoption of a plan relating to the liquidation or dissolution of the Company (other than the Company’s liquidation into a newly formed holding company meeting the requirements of the following paragraph).

Notwithstanding the foregoing, a transaction described in clause (b) or (c) above will not be deemed to involve a Change of Control if (1) the Company becomes a direct or indirect wholly-owned subsidiary of a holding company (which shall include a direct or indirect parent company of such holding company) and (2) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as, and hold in substantially the same proportions as, the holders of the Company’s Voting Stock immediately prior to that transaction.

If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time.

In a Change of Control Offer, the Company shall be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to, but not including, the repurchase date (a “Change of Control Payment”).

10

(b) Within 30 days following any Change of Control Triggering Event or, at the Company’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice shall be mailed or sent electronically pursuant to the Applicable Procedures to Holders of the Notes with a copy to the Trustee describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase such Notes on the repurchase date specified in the applicable notice, which date shall be no earlier than 10 days and no later than 60 days from the date on which such notice is mailed or sent (a “Change of Control Payment Date”).

(c) The notice shall, if mailed or sent prior to the date of consummation of the Change of Control, state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring prior to or on the applicable Change of Control Payment Date specified in the notice.

(e) The Company shall not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if (i) a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company, and the third party purchases all Notes properly tendered and not withdrawn under its offer or (ii) in connection with or in contemplation of any Change of Control, the Company or a third party makes an offer to purchase in the manner, at the times and otherwise in compliance with the requirements of a Change of Control Offer (an “Alternate Offer”) any and all Notes validly tendered at a cash price equal to or higher than the Change of Control Payment, and the Company or the third party purchases all Notes properly tendered and not withdrawn under the Alternate Offer.

(f) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict.

All Global Notes will be exchanged by the Company for Certificated Notes if:

(1) the Company delivers to the Trustee notice from the Depositary (A) that it is unwilling or unable to continue to act as Depositary for the Global Notes and a successor Depositary is not appointed by the Company within 90 days after the date of such notice from the Depositary or (B) that it is no longer a clearing agency registered under the Exchange Act at a time when it is required to be registered and a successor Depositary is not appointed by the Company within 90 days after the date of such notice from the Depositary;

(2) the Company, in its sole discretion, delivers to the Trustee an Officer’s Certificate to the effect that it elects to cause the issuance of Certificated Notes; or

(3) upon request of the Trustee or Holders of a majority of the principal amount of outstanding Notes if there shall have occurred and be continuing a Default or Event of Default with respect to the Notes.

Upon the occurrence of any of the preceding events in (1), (2) or (3) above, Certificated Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.8 and 2.11 of the Indenture. A Global Note may not be exchanged for another Note other than as provided in this Section 4.01(a); however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 4.01(b) or (c) hereof.

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of the Indenture and the Applicable Procedures. Beneficial interests in the Global Notes will be subject to restrictions on transfer comparable to those set forth herein. Transfers of beneficial interests in the Global Notes also will require compliance with either subparagraph (1) or (2) below, as applicable, as well as one or more of the other following subparagraphs, as applicable:

(1) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Global Note may be transferred to persons who take delivery thereof in the form of a beneficial interest in the same Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 4.01(b)(1).

(2) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are not subject to Section 4.01(b)(1) above, the transferor of such beneficial interest must deliver to the Registrar either: (A)(1) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial

14

interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged; and (2) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase; or (B)(1) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to cause to be issued a Certificated Note in an amount equal to the beneficial interest to be transferred or exchanged; and (2) instructions given by the Depositary to the Registrar containing information regarding the person in whose name such Certificated Note shall be registered to effect the transfer or exchange referred to in (B)(1) above;

(c) Transfer or Exchange of Beneficial Interests in Global Notes for Certificated Notes. If any holder of a beneficial interest in a Global Note proposes to exchange such beneficial interest for a Certificated Note or to transfer such beneficial interest to a person who takes delivery thereof in the form of a Certificated Note, then, if the exchange or transfer complies with the requirements of Section 4.01(a) of this Supplemental Indenture and upon satisfaction of the conditions set forth in Section 4.01(b)(2) of this Supplemental Indenture, the Trustee shall cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 4.01(f) hereof, and the Company shall execute and, upon receipt of a Company Order pursuant to Section 2.3 of the Indenture, the Trustee shall authenticate and deliver to the person designated in the instructions a Certificated Note in the appropriate principal amount. Any Certificated Note issued in exchange for a beneficial interest pursuant to this Section 4.01(c) shall be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest requests through instructions to the Registrar from or through the Depositary and the Participant or Indirect Participant. The Trustee shall deliver such Certificated Notes to the persons in whose names such Notes are so registered.

(d) Transfer and Exchange of Certificated Notes for Beneficial Interests in Global Notes. A Holder of a Certificated Note may exchange such Certificated Note for a beneficial interest in a Global Note or transfer such Certificated Notes to a person who takes delivery thereof in the form of a beneficial interest in a Global Note at any time. Upon receipt of a request for such an exchange or registration of transfer, the Trustee shall cancel the applicable Certificated Note and increase or cause to be increased the aggregate principal amount of one of the applicable Global Notes. If any such exchange or registration of transfer from a Certificated Note to a beneficial interest in a Global Note is effected pursuant to this Section 4.01(d) at a time when a Global Note has not yet been issued, the Company shall issue and, upon receipt of a Company Order in accordance with Section 2.3 of the Indenture, the Trustee shall authenticate one or more Global Notes in an aggregate principal amount equal to the principal amount of Certificated Notes so transferred.

(e) Transfer and Exchange of Certificated Notes for Certificated Notes. A Holder of Certificated Notes may transfer such Certificated Notes to a person who takes delivery thereof in the form of a Certificated Note. Upon request by a Holder of Certificated Notes and such Holder’s compliance with the provisions of this Section 4.01(e), the Registrar shall register the transfer or exchange of Certificated Notes. Prior to such registration of transfer or exchange, the requesting Holder must present or surrender to the Registrar the Certificated Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by its attorney, duly authorized in writing. Upon receipt of a request to register such a transfer, the Registrar shall register the Certificated Notes pursuant to the instructions from the Holder thereof.

(g) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Certificated Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.12 of the Indenture. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Certificated Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a person who shall take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

Nordson Corporation, an Ohio corporation (hereinafter called the “Company,” which term includes any successors under the Indenture hereinafter referred to), promises to pay interest on the principal amount of this Security at the rate of 4.500% per annum from September 9, 2024 or the most recently occurred Interest Payment Date from the date of issuance of additional Securities, until maturity. To the extent it is lawful, the Company promises to pay interest on any interest payment due on such principal amount but unpaid at a rate of 4.500% per annum compounded semi-annually.

The Company will pay interest semi-annually in arrears on June 15 and December 15 of each year (each, an “Interest Payment Date”), commencing December 15, 2024. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid on the Securities, from the date of the original issuance. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months.

The Company shall pay interest on the Securities (except defaulted interest) to the persons who are the registered Holders at the close of business on the Record Date on the next preceding Interest Payment Date. Holders must surrender Securities to a Paying Agent to collect principal payments. Principal of, premium, if any, and interest on the Securities will be payable in United States Dollars at the office or agency of the Company maintained for such purpose, in the contiguous United States or at the option of the Company, payment of interest may be made by check mailed to the Holders of the Securities at the addresses set forth upon the registry books of the Company; provided, however, Holders of Global Notes will be entitled to receive interest payments (other than at maturity) by wire transfer of immediately available funds, if appropriate wire transfer instructions have been received in writing by the Trustee not fewer than 15 days prior to the applicable Interest Payment Date. Such wire instructions, upon receipt by the Trustee, shall remain in effect until revoked by such Holder. No service charge will be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.11, 3.6 and 9.6 of the Indenture).

Initially, U.S. Bank Trust Company, National Association will act as Paying Agent and Registrar. The Company may change any Paying Agent, Registrar or co-Registrar without notice to the Holders. The Company or any of its Subsidiaries may, subject to certain exceptions, act as Paying Agent, Registrar or co-Registrar.

The Company issued the Securities under an Indenture, dated as of September 13, 2023, as supplemented (the “Indenture”), between the Company and the Trustee. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The Securities are unlimited in aggregate principal amount. The terms of the Securities include those stated in the Indenture

A-5

and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as in effect on the date of the Indenture. The Securities are subject to all such terms, and Holders of the Securities are referred to the Indenture and said Act for a statement of them. To the extent any provision of the Securities conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Securities are senior, general obligations of the Company. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by the provisions of the Indenture, (b) authorizes and directs the Trustee on his behalf to take such action as may be provided in the Indenture and (c) appoints the Trustee as his attorney-in-fact for such purpose.

(a) Prior to November 15, 2029 (one month prior to their maturity date) (the “Par Call Date”), the Company may redeem the Securities at its option, at any time in whole or from time to time in part, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(i) 100% of the principal amount of the Securities to be redeemed; and

(ii) (a) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed, in each case discounted to the redemption date (assuming the Securities matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points, less (b) interest accrued thereon to the date of redemption,

plus, in either clause (i) or (ii) above, accrued and unpaid interest thereon to, but not including, the redemption date.

(b) The Securities shall be redeemable, at the option of the Company, at any time on or after the Par Call Date, in whole or in part, at any time from time to time, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest on the Securities to be redeemed to, but not including, the date of redemption.

(c) In each of paragraphs (a) and (b) of this Section 5, the Company shall pay accrued and unpaid interest on the principal amount being redeemed to the date of redemption.

The Securities are in registered form, without coupons, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may register the transfer of, or exchange Securities 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 and fees required by law or permitted by the Indenture.

The registered Holder of a Security may be treated as the owner of it for all purposes.

A-6

Subject to applicable abandoned property law, if money for the payment of principal or interest remains unclaimed for two years, the Trustee and the Paying Agent(s) will pay the money back to the Company at its written request. After that, all liability of the Trustee and such Paying Agent(s) with respect to such money shall cease.

Except as set forth in the Indenture, the Company shall have irrevocably deposited or caused to be deposited with the Trustee as trust funds specifically pledged as security for and dedicated solely to the benefit of the Holders of such Securities (i) in the case of Securities denominated in Dollars, cash in Dollars and/or U.S. Government Obligations or (ii) in the case of Securities denominated in a Foreign Currency (other than composite currency), money and/or Foreign Government Obligations, which through the payment of interest and principal in respect thereof in accordance with their terms, will provide (and without reinvestment and assuming no tax liability will be imposed on such Trustee), not later than one day before the due date of any payment of money, an amount in cash, sufficient, in the opinion of a nationally recognized firm of independent public accountants or investment bank expressed in a written certification thereof delivered to the Trustee, to pay and discharge each installment of principal and interest, on and any mandatory sinking fund payments in respect of all the Securities on the dates such installments of principal or interest and such sinking fund payments are due, the Company may defease, or be discharged from, as the case may be, certain provisions of the Indenture and the Securities (as specified in the Indenture and the Supplemental Indenture, but in each case excluding its obligation to pay the principal of, premium, if any, and interest on the Securities). Upon satisfaction of certain additional conditions set forth in the Indenture, the Company may elect to have its obligations and the obligations of any Subsidiary that becomes a guarantor, if applicable, discharged with respect to outstanding Securities.

The Company, any Subsidiary that becomes a guarantor, if applicable, and the Trustee may enter into a supplemental indenture for certain limited purposes without the consent of the Holders. Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented with the written consent of the Holders of not less than a majority in aggregate principal amount of the Securities then outstanding, and any existing Default or Event of Default or compliance with any provision may be waived with the consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. Without notice to or consent of any Holder, the parties thereto may under certain circumstances amend or supplement the Indenture or the Securities to, among other things, cure any ambiguity, defect or inconsistency, or make any other change that does not adversely affect the rights of any Holder of a Security.

The Indenture imposes certain limitations on the ability of the Company and any Subsidiary to, among other things, incur Liens, enter into Sale and Leaseback Transactions, merge or consolidate with any other person or transfer (by lease, assignment or otherwise) substantially all of the properties and assets of the Company. The limitations are subject to a number of important qualifications and exceptions. The Company must periodically report to the Trustee on compliance with such limitations.

When a successor assumes all the obligations of its predecessor under the Securities and the Indenture, the predecessor will be released from those obligations.

If an Event of Default with respect to the Securities occurs and is continuing (other than an Event of Default relating to bankruptcy, insolvency or reorganization of the Company), then either the Trustee or the Holders of 25% in aggregate principal amount of the Securities then outstanding may declare all Securities to be due and payable immediately in the manner and with the effect provided in the Indenture. Holders of the Securities may not enforce the Indenture or the Securities, except as provided in the Indenture. The Trustee may require indemnity or security satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Securities may direct the Trustee in its exercise of any trust or power with respect to such Securities. The Trustee may withhold from Holders of the Securities notice of any continuing Default or Event of Default (except a Default in payment of principal or interest) if it determines that withholding notice is in their interest.

The Trustee and each Agent under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or any Subsidiary that becomes a guarantor of the Securities, if applicable, or any of their Subsidiaries or any of their respective Affiliates, and may otherwise deal with such persons as if it were not the Trustee or such agent.

No recourse for the payment of the principal of, premium, if any, or interest on the Securities or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company or any Subsidiary that becomes a guarantor of the Securities, if applicable, in the Indenture, or in the Securities or because of the creation of any indebtedness represented thereby, shall be had against any past, present or future directors, officers, employees or securityholders of the Company or any Subsidiary that becomes a guarantor of the Securities, if applicable, or of any successor person thereof, except as an obligor or guarantor of the Securities pursuant to the Indenture. Each Holder, by accepting the Securities, waives and releases all such liability.

This Security shall not be valid until the Trustee or authenticating agent manually signs the certificate of authentication on the other side of this Security.
