AGREEMENT:

In consideration of the premises and mutual covenants herein and for other valuable consideration, Nordson, the Administrative Agent and the Required Banks agree as follows:

Section 1. Definitions. Unless otherwise defined herein, each capitalized term used in this Amendment and not defined herein shall be defined in accordance with the Credit Agreement.

Section 2. Amendments.

2.1 Amendment to Section 1.01. The following definitions of “Commitment Percentage”, “Defaulting Lender” and “Total Commitment Amount” are hereby amended and restated in their entirety as follows:

“Commitment Percentage” shall mean, at any time for any Bank, a percentage obtained by dividing such Bank’s Revolving Commitment by the Total Commitment Amount. The Commitment Percentage for each Bank as of the First Amendment Effective Date is set forth opposite such Bank’s name under the column headed “Commitment Percentage” as described in Schedule 1-A hereto.

“Defaulting Bank” shall mean, subject to Section 2.10(b), any Bank that (a) has failed to (i) fund all or any portion of its Loans within two Business Days of the date such Loans were required to be funded hereunder unless such Bank notifies the Agent and the Borrowers in writing that such failure is the result of such Bank’s determination that one

or more conditions precedent to funding (each of which conditions precedent, together with any applicable default, shall be specifically identified in such writing) has not been satisfied, or (ii) pay to the Agent, any Swing Line Bank or any other Bank any other amount required to be paid by it hereunder (including in respect of its participation in Swing Loans) within two Business Days of the date when due, (b) has notified the Borrowers, the Agent or Swing Line Bank in writing that it does not intend to comply with its funding obligations hereunder, or has made a public statement to that effect (unless such writing or public statement relates to such Bank’s obligation to fund a Loan hereunder and states that such position is based on such Bank’s determination that a condition precedent to funding (which condition precedent, together with any applicable default, shall be specifically identified in such writing or public statement) cannot be satisfied), (c) has failed, within three Business Days after written request by the Agent or the Borrowers, to confirm in writing to the Agent and the Borrowers that it will comply with its prospective funding obligations hereunder (provided that such Bank shall cease to be a Defaulting Bank pursuant to this clause (c) upon receipt of such written confirmation by the Agent and the Borrowers), (d) has, or has a direct or indirect parent company that has, (i) become the subject of a proceeding under any Debtor Relief Law, or (ii) had appointed for it a receiver, custodian, conservator, trustee, administrator, assignee for the benefit of creditors or similar Person charged with reorganization or liquidation of its business or assets, including the Federal Deposit Insurance Corporation or any other state or federal regulatory authority acting in such a capacity or (e) has become the subject of a Bail-in Action; provided that a Bank shall not be a Defaulting Bank solely by virtue of the ownership or acquisition of any equity interest in that Bank or any direct or indirect parent company thereof by a Governmental Authority so long as such ownership interest does not result in or provide such Bank with immunity from the jurisdiction of courts within the United States or from the enforcement of judgments or writs of attachment on its assets or permit such Bank (or such Governmental Authority) to reject, repudiate, disavow or disaffirm any contracts or agreements made with such Bank. Any reasonable determination by the Agent that a Bank is a Defaulting Bank under any one or more of clauses (a) through (d) above shall be conclusive and binding absent manifest error, and such Bank shall be deemed to be a Defaulting Bank (subject to Section 2.10(B)) upon delivery of written notice of such determination to the Borrower, each Swing Line Bank and each Bank.

“Total Commitment Amount” shall mean, as of the First Amendment Effective Date, the principal amount of Eight Hundred and Fifty Million Dollars ($850,000,000) (or its Dollar Equivalent in Alternate Currency), or such lesser or greater amount as shall be determined pursuant to Section 2.07 hereof; provided, however, that, for the purposes of determining the Total Commitment Amount, Agent may, in its discretion, calculate the Dollar Equivalent of any Loan on any Business Day selected by Agent.

2.2 Amendment to Section 1.01. The definition of “LIBOR Rate” is hereby amended by replacing the “.” at the end of clause (b) thereof with a “,” and adding the following proviso at the end of such definition:

“provided, that (i) to the extent a comparable or successor rate is approved by the Agent in connection with any rate set forth in this definition, the approved rate shall be applied in a manner consistent with market practice; provided, further that to the extent such market practice is not administratively feasible for the Agent, such approved rate shall be applied in a manner as otherwise reasonably determined by the Agent.”

2.4 Amendment to Section 2.07. Section 2.07 of the Credit Agreement is hereby amended by amending and restating clause (b)(i) thereof as follows:

“(i) At any time upon written notice to Agent, Nordson may request that the Total Commitment Amount be increased by an amount not to exceed Two Hundred Fifty Million Dollars ($250,000,000) in the aggregate for all such increases from the Closing Date until the last day of the Commitment Period, provided that (A) no Default or Event of Default has occurred and is continuing at the time of such request and on the date of any such increase and (B)

Nordson shall have delivered to Agent, together with such written notice, a copy of Nordson’s duly adopted corporate resolutions, in form and substance satisfactory to Agent, that authorize the borrowing of the requested increase in the Total Commitment Amount, which resolutions shall be certified by the Secretary of Nordson as being true, correct, complete and in full force and effect, provided, however, that Nordson may not make any such requests after the First Amendment Effective Date. Upon receipt of any such request, Agent shall deliver a copy of such request to each Bank. Nordson shall set forth in such request the amount of the requested increase in the Total Commitment Amount (which in each case shall be in a minimum amount of Twenty-Five Million Dollars ($25,000,000)) and the date on which such increase is requested to become effective (which shall be not less than 10 Business Days nor more than sixty (60) days after the date of such request and that, in any event, must be at least ninety (90) days prior to the last day of the Commitment Period), and shall offer each Bank the opportunity to increase its Revolving Commitment. Each Bank shall, by notice to Nordson and Agent given not more than ten (10) days after the date of Agent’s notice, either agree to increase its Revolving Commitment by all or a portion of the offered amount (each such Bank so agreeing being an “Increasing Bank”) or decline to increase its Revolving Commitment (and any such Bank that does not deliver such a notice within such period of 10 days shall be deemed to have declined to increase its Revolving Commitment and each Bank so declining or being deemed to have declined being a “Non-Increasing Bank”). If, on the 10th day after Agent shall have delivered notice as set forth above, the Increasing Banks shall have agreed pursuant to the preceding sentence to increase their Revolving Commitments by an aggregate amount less than the increase in the Total Commitment Amount requested by Nordson, Nordson may arrange for one or more banks or other entities that are reasonably acceptable to Agent (each such Person so agreeing being an “Augmenting Bank”) so long as such Augmenting Bank shall have a Revolving Commitment of not less than Ten Million Dollars ($10,000,000), and Nordson and each Augmenting Bank shall execute all such documentation as Agent shall reasonably specify to evidence its Revolving Commitment and/or its status as a Bank with a Revolving Commitment hereunder. Any increase in the Total Commitment Amount may be made in an amount that is less than the increase requested by Nordson if Nordson is unable to arrange for, or chooses not to arrange for, Augmenting Banks, in the full amount. If Increasing Banks and/or Augmenting Banks offer Revolving Commitment increases or new Revolving Commitments, as the case may be, in excess of the aggregate increase amount requested by Nordson, then Agent shall, in consultation with Nordson, determine each such Increasing Bank’s or Augmenting Bank’s percentage of the increased amount.”

2.5 Amendment to Section 5.04. Section 5.04 of the Credit Agreement is hereby amended and restated as follows:

“Section 5.04 Financial Covenants.

(a) Leverage Ratio. Nordson covenants that it shall not suffer or permit the Leverage Ratio to exceed (i) during the first two fiscal quarters of any Leverage Step-Up Period, 4.00 to 1.00, (ii) during the third and fourth fiscal quarters of any Leverage Step-Up Period, 3.75 to 1.00 and (iii) at all other times, 3.50 to 1.00.

Notwithstanding anything to the contrary in any Loan Document or in any other agreement, arrangement or understanding among any such parties, each party hereto acknowledges that any liability of any EEA Financial Institution arising under any Loan Document, to the extent such liability is unsecured, may be subject to the write-down and conversion powers of an EEA Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by:

(a) the application of any Write-Down and Conversion Powers by an EEA Resolution Authority to any such liabilities arising hereunder which may be payable to it by any party hereto that is an EEA Financial Institution; and

(b) the effects of any Bail-in Action on any such liability, including, if applicable:

(i) a reduction in full or in part or cancellation of any such liability;

(ii) a conversion of all, or a portion of, such liability into shares or other instruments of ownership in such EEA Financial Institution, its parent undertaking, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of any rights with respect to any such liability under this Agreement or any other Loan Document; or

(iii) the variation of the terms of such liability in connection with the exercise of the write-down and conversion powers of any EEA Resolution Authority.”
