        declare such Indebtedness to be), due and payable before its stated maturity or before its regularly scheduled dates of payment, or (iii) as a consequence of the occurrence or continuation of any event or condition (other than the passage of time

      “Section 10.7. Financial Covenants. 

       

      (a)    Consolidated Net Leverage Ratio.  The Company will not permit its Consolidated Net Leverage Ratio at the end of any fiscal
        quarter to exceed 3.50:1.00; provided that, upon notice by the Company to the holders of Notes, as of the last day of each of the four consecutive fiscal quarters immediately following a Qualified
        Acquisition (the “Adjustment Period”), such ratio may be greater than 3.50 to 1.00, but in no event greater than 4.00 to 1.00, and in which event, the Company shall be obligated to pay the Incremental
        Interest provided for in Section 1.3; provided further that in no event may the Consolidated Net Leverage Ratio be greater than 3.50 to 1.00 following a Qualified Acquisition on more than three (3) separate
        occasions during the term of this Agreement and the Consolidated Net Leverage Ratio may not exceed 3.50 to 1.00 for at least two (2) consecutive fiscal quarters in between each Adjustment Period.  The Consolidated Net Leverage Ratio will be
        calculated at the end of each fiscal quarter, using the results of the twelve-month period ending with that fiscal quarter, it being understood that to the extent any Qualified Acquisition shall have occurred during such period, the Consolidated
        Net Leverage Ratio shall be calculated as if such acquisition occurred at the beginning of such period.

       

      Notwithstanding the foregoing, if any Material Credit Facility includes provisions related to a leverage ratio (including any substantially similar concepts and any related
        definitions, the “MFL Leverage Covenant Provisions”) and such MFL Leverage Covenant Provisions are more favorable to the lenders thereunder (including, without limitation, if the leverage ratio in such
        Material Credit Facility is calculated on a gross basis), such MFL Leverage Covenant Provisions will be incorporated herein, mutatis mutandi, as if set forth fully in this Agreement, effective beginning on
        the date on which such MFL Leverage Covenant Provisions are effective under such Material Credit Facility.

       

      (b)   Consolidated Interest Coverage Ratio.  The Company will not permit its Consolidated Interest Coverage Ratio at the end of any
        fiscal quarter to be less than 2.50:1.00.  The Consolidated Interest Coverage Ratio will be calculated at the end of each fiscal quarter, using the results of the twelve-month period ending with that fiscal quarter.  Notwithstanding the foregoing,
        if any Material Credit Facility includes provisions related to a consolidated interest coverage ratio (including any substantially similar concepts and any related definitions, the “MFL Interest Coverage Covenant
          Provisions”; and together with the MFL Leverage Covenant Provisions, the “MFL Covenant Provisions”) and such MFL Interest Coverage Covenant Provisions are
        more favorable to the lenders thereunder, such MFL Interest Coverage Covenant Provisions will be incorporated herein, mutatis mutandi, as if set forth fully in this Agreement, effective beginning on the
        date on which such MFL Interest Coverage Covenant Provisions are effective under such Material Credit Facility.  For purposes of clarification, as of May 18, 2022, the minimum Consolidated Interest Coverage Ratio under this Section 10.7(b) shall be
        3.00 to 1.00.”

        -3-

        
          

      

      (c)    With respect to clauses (a) and (b) of this Section 10.7, (i) provided that no Default or Event of Default has occurred and is
        then continuing, if such MFL Covenant Provision is subsequently amended or modified in the Material Credit Facility, such amendment or modification shall be deemed incorporated by reference into this Agreement, mutatis

          mutandi, as if set forth fully in this Agreement, effective beginning on the date on which such amendment or modification is effective in the Material Credit Facility, (ii) provided, further, that
        the Consolidated Net Leverage Ratio shall never exceed 3.50:1.00 or, subject to Section 10.7(a), immediately following a Qualified Acquisition, such ratio shall never exceed 4.00 to 1.00, (iii) provided, further,
        that the minimum Consolidated Interest Coverage Ratio shall never be less than 2.50 to 1.00 under clause (b) of this Section 10.7, and (iv) provided, further, that in the event that any fee is paid to any
        party under the Material Credit Facility solely to effectuate any amendment or modification of such MFL Covenant Provision, the holders of the Notes shall have received an Equivalent Fee on a pro rata basis
        prior to or concurrently with the effectiveness of any such amendment or modification.  “Equivalent Fee” means an amount equal to the percentage determined by dividing the fee paid under the Material Credit
        Facility by the principal outstanding amount under the Material Credit Facility multiplied by the aggregate outstanding principal amount of the Notes.

       

      (d)    Priority Debt.  The Company will not permit its Priority Debt to exceed 25% of Consolidated Total Assets as of the last day of
        any fiscal quarter of the Company.”

       

      Section 1.6.    Section 11(j) of the Note Purchase Agreement shall be and is hereby amended in its entirety and replaced with the following:

       

      “(j)   one or more final judgments or orders for the payment of money aggregating in excess of the Threshold Amount (or its equivalent in the relevant currency of payment and to
        the extent not covered by independent third-party insurance as to which the insurer does not dispute coverage), including any such final order enforcing a binding arbitration decision, are rendered against one or more of the Company and its
        Subsidiaries and which judgments are not, within 60 days after entry thereof, bonded, discharged or stayed pending appeal, or are not discharged within 60 days after the expiration of such stay; or”

       

      Section 1.7.   The definition of “Consolidated EBITDA” in Schedule A of the Note Purchase Agreement shall be and is hereby amended to read as follows:

       

      “‘Consolidated EBITDA’ means, for any period, for the Company and its Subsidiaries on a
        consolidated basis, an amount equal to Consolidated Net Income for such period plus (a) the following to the extent deducted in calculating such Consolidated Net Income and without duplication: (i)
        Consolidated Interest Charges for such period, (ii) the provision for federal, state, local and foreign income taxes payable by the Company and its Subsidiaries for such period, (iii) the amount of depreciation and amortization expense for such
        period, (iv) other expenses (excluding depreciation and amortization) of the Company and its Subsidiaries reducing such Consolidated Net Income which do not represent a cash item in such period or any future period, and (v) acquisition and
        integration expenses incurred by the Company and its Subsidiaries during such period in an aggregate amount not to exceed fifteen percent (15%) of Consolidated EBITDA for such period prior to giving effect to all add‐backs pursuant to this clause
        (v) for such period and minus (b) all non‐cash items increasing Consolidated Net Income for such period.”

       

      

      
        -4-

        
          

      

      Section 1.8.   The definition of “Consolidated Net Income” in Schedule A of the Note Purchase Agreement shall be and is hereby amended to read as follows:

       

      “‘Consolidated Net Income’ means, for any period, for the Company and its Subsidiaries on a
        consolidated basis, the net income of the Company and its Subsidiaries (excluding extraordinary gains but including extraordinary losses) for that period; provided that Consolidated Net Income shall exclude
        any income (or loss) for such period of any Person if such Person is not a Subsidiary, except that the Company’s equity in the net income of any such Person for such period shall be included in Consolidated Net Income up to the aggregate amount of
        cash actually distributed by such Person during such period to the Company or a Subsidiary as a dividend or other distribution.”

      Section 1.10. The definition of “Material Credit Facility” in Schedule A of the Note Purchase Agreement shall be and is hereby amended to read as follows:

       

      “‘Material Credit Facility’ means, as to the Company and its Subsidiaries,

    First Amendment to Note Purchase Agreement

     

    This First Amendment dated as of May 18, 2022 (the or this “First

          Amendment”) to the Note Purchase Agreement dated December 8, 2016 is among Littelfuse Netherlands C.V., a limited partnership (commanditaire vennootschap) established under the laws of the
        Netherlands (the “Company”), Littelfuse, Inc., a Delaware corporation (the “Parent Guarantor” and, together with the Company, the “Obligors”)
        and each of the institutions which is a signatory to this First Amendment (collectively, the “Noteholders”).

     

    Recitals:

     

    
      
        A.       The Obligors and each of the Noteholders have heretofore entered into the Note Purchase Agreement dated December 8, 2016 (the “Note Purchase Agreement”).  The
          Company has heretofore issued (i) €117,000,000 aggregate principal amount of its 1.14% Senior Notes, Series A, due December 8, 2023 (the “Series A Notes”) and (ii) €95,000,000 aggregate principal amount of its 1.83% Senior Notes, Series B, due December 8, 2028 (the “Series B Notes”; collectively with the Series B Notes, the “Notes”) pursuant to the Note
          Purchase Agreement.  The Noteholders are the holders of at least 51% of the outstanding principal amount of the Notes.

      

    

     

    B.         The Obligors and the Noteholders now desire to amend the Note Purchase Agreement in the respects, but only in the respects, hereinafter set forth.

     

    C.         Capitalized terms used herein shall have the respective meanings ascribed thereto in the Note Purchase Agreement unless herein defined or the context shall otherwise require.

     

    D.         All requirements of law have been fully complied with and all other acts and things necessary to make this First Amendment a valid, legal and binding instrument according to its terms for
      the purposes herein expressed have been done or performed.

     

    Now, therefore, upon the full and complete satisfaction of the conditions precedent to the effectiveness of this First Amendment set forth in Section 3.1 hereof, and in consideration
        of good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the Obligors and the Noteholders do hereby agree as follows:

     

    Section 1.           Amendments.

     

    Section 1.1.      Section 1.2 of the Note Purchase Agreement shall be and is hereby amended by replacing “Consolidated Leverage Ratio” where it appears therein with “Consolidated Net Leverage Ratio”.

     

    Section 1.2.     The Note Purchase Agreement shall be and is hereby amended by replacing “Littelfuse Netherland C.V.” where it appears therein with “Littelfuse Netherlands B.V.”.

    Section 1.3.       Section 10.6(i) of the Note Purchase Agreement shall be and is hereby amended in its entirety and replaced with the following:

     

    “(i)     Liens on assets of Foreign Subsidiaries securing Indebtedness of Foreign Subsidiaries permitted under Section 10.7 and in an aggregate amount not to exceed the Threshold
      Amount at any one time outstanding, and any refinancings, refundings, replacements, renewals or extensions thereof; provided that (i) the property covered thereby is not changed, (ii) the amount secured or
      benefited thereby is not increased except by an amount equal to a reasonable premium or other reasonable amount paid, and fees and expenses reasonably incurred, in connection with such refinancing, refunding, replacement, renewal or extension and by
      an amount equal to any existing commitments unutilized thereunder, (iii) the direct or any contingent obligor with respect thereto is not changed, and (iv) any extension, renewal or replacement of the obligations secured or benefited thereby is
      permitted by Section 10.7;”

     

    Section 1.4.       Section 11(f) of the Note Purchase Agreement shall be and is hereby amended in its entirety and replaced with the following:

     

    “(f)    (i) either Obligor or any Subsidiary is in default (as principal or as guarantor or other surety) in the payment of any principal of or premium or make‐whole amount or
      interest on any Indebtedness that is outstanding in an aggregate principal amount of at least the Threshold Amount (or its equivalent in the relevant currency of payment) beyond any period of grace provided with respect thereto, or (ii) either
      Obligor or any Subsidiary is in default in the performance of or compliance with any term of any evidence of any Indebtedness in an aggregate outstanding principal amount of at least the Threshold Amount (or its equivalent in the relevant currency of
      payment) or of any mortgage, indenture or other agreement relating thereto or any other condition exists, and as a consequence of such default or condition such Indebtedness has become, or has been declared (or one or more Persons are entitled to
      declare such Indebtedness to be), due and payable before its stated maturity or before its regularly scheduled dates of payment, or (iii) as a consequence of the occurrence or continuation of any event or condition (other than the passage of time or
      the right of the holder of Indebtedness to convert such Indebtedness into equity interests), (x) either Obligor or any Subsidiary has become obligated to purchase or repay Indebtedness before its regular maturity or before its regularly scheduled
      dates of payment in an aggregate outstanding principal amount of at least the Threshold Amount (or its equivalent in the relevant currency of payment), or (y) one or more Persons have the right to require either Obligor or any Subsidiary so to
      purchase or repay such Indebtedness; or”

     

    Section 1.5.      Section 10.7 of the Note Purchase Agreement shall be and is hereby amended in its entirety and replaced with the following:

     

    
      -2-

      
        

    

    “Section 10.7.          Financial Covenants. 

     

    (a)      Consolidated Net Leverage Ratio.  The Obligors will not permit the Parent Guarantor’s Consolidated Net Leverage Ratio at the end
      of any fiscal quarter to exceed 3.50:1.00; provided that, upon notice by the Parent Guarantor to the holders of Notes, as of the last day of each of the four consecutive fiscal quarters immediately following
      a Qualified Acquisition (the “Adjustment Period”), such ratio may be greater than 3.50 to 1.00, but in no event greater than 4.00 to 1.00, and in which event, the Obligors shall be obligated to pay the
      Incremental Interest provided for in Section 1.2; provided further that in no event may the Consolidated Net Leverage Ratio be greater than 3.50 to 1.00 following a Qualified Acquisition on more than three
      (3) separate occasions during the term of this Agreement and the Consolidated Net Leverage Ratio may not exceed 3.50 to 1.00 for at least two (2) consecutive fiscal quarters in between each Adjustment Period.  The Consolidated Net Leverage Ratio will
      be calculated at the end of each fiscal quarter, using the results of the twelve-month period ending with that fiscal quarter, it being understood that to the extent any Qualified Acquisition shall have occurred during such period, the Consolidated
      Net Leverage Ratio shall be calculated as if such acquisition occurred at the beginning of such period.

     

    Notwithstanding the foregoing, if any Material Credit Facility includes provisions related to a leverage ratio (including any substantially similar concepts and any related
      definitions, the “MFL Leverage Covenant Provisions”) and such MFL Leverage Covenant Provisions are more favorable to the lenders thereunder (including, without limitation, if the leverage ratio in such
      Material Credit Facility is calculated on a gross basis), such MFL Leverage Covenant Provisions will be incorporated herein, mutatis mutandi, as if set forth fully in this Agreement, effective beginning on
      the date on which such MFL Leverage Covenant Provisions are effective under such Material Credit Facility.

     

    (b)     Consolidated Interest Coverage Ratio.  The Obligors will not permit the Parent Guarantor’s Consolidated Interest Coverage Ratio at
      the end of any fiscal quarter to be less than 2.50:1.00.  The Consolidated Interest Coverage Ratio will be calculated at the end of each fiscal quarter, using the results of the twelve-month period ending with that fiscal quarter.  Notwithstanding
      the foregoing, if any Material Credit Facility includes provisions related to a consolidated interest coverage ratio (including any substantially similar concepts and any related definitions, the “MFL Interest
        Coverage Covenant Provisions”; and together with the MFL Leverage Covenant Provisions, the “MFL Covenant Provisions”) and such MFL Interest Coverage Covenant
      Provisions are more favorable to the lenders thereunder, such MFL Interest Coverage Covenant Provisions will be incorporated herein, mutatis mutandi, as if set forth fully in this Agreement, effective
      beginning on the date on which such MFL Interest Coverage Covenant Provisions are effective under such Material Credit Facility.  For purposes of clarification, as of May 18, 2022, the minimum Consolidated Interest Coverage Ratio under this Section
      10.7(b) shall be 3.00 to 1.00.”

     

    

    
      -3-

      
        

    

    (c)     With respect to clauses (a) and (b) of this Section 10.7, (i) provided that no Default or Event of Default has occurred and is then
      continuing, if such MFL Covenant Provision is subsequently amended or modified in the Material Credit Facility, such amendment or modification shall be deemed incorporated by reference into this Agreement, mutatis
        mutandi, as if set forth fully in this Agreement, effective beginning on the date on which such amendment or modification is effective in the Material Credit Facility, (ii) provided, further, that
      the Consolidated Net Leverage Ratio shall never exceed 3.50:1.00 or, subject to Section 10.7(a), immediately following a Qualified Acquisition, such ratio shall never exceed 4.00 to 1.00, (iii) provided, further,

      aggregate amount of cash actually distributed by such Person during such period to the Parent Guarantor or a Subsidiary as a dividend or other distribution.”
