 Exhibit 10.1 
 SECOND AMENDMENT 
 SECOND AMENDMENT dated as of December 1, 2006 (this
“Second Amendment”) by and among HARVARD BIOSCIENCE, INC., a Delaware corporation (the “Borrower”); the lenders identified on the signature pages hereto (individually, a “Lender” and collectively,
the “Lenders”); and Brown Brothers Harriman & Co., as agent for the Lenders (in such capacity, together with its successors in such capacity, the “Agent”). 
 The Borrower, the Lenders and the Agent are parties to a Revolving Credit Loan Agreement dated as of November 21, 2003 (as amended by a First
Amendment dated March 14, 2006 and heretofore modified and in effect on the date hereof, the “Loan Agreement”), pursuant to which the Lenders have agreed to make certain revolving credit loans to the Borrower. The Borrower,
Lenders and Agent wish to extend the maturity date under the Loan Agreement to December 1, 2009 and amend the Loan Agreement in certain other respects, all on the terms and conditions hereinafter set forth. 
 NOW, THEREFORE, in consideration of the foregoing and the mutual covenants herein contained, and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties signatory hereto agree as follows: 
 1. Definitions. Except as otherwise
defined in this Second Amendment, terms defined in the Loan Agreement are used herein as defined therein. 
 2. Amendments. Subject to
the satisfaction of the conditions precedent specified in Section 4 below, but effective as of the date hereof, the Loan Agreement shall be amended as follows: 
 (a) In order to give effect to the extension of the Maturity Date, 
 (i) the first sentence
of Section 1.1 of the Loan Agreement shall be amended to read in its entirety as follows: 
 “1.1. Recitals;
Maximum Line Commitment. The Borrower wishes to establish a revolving credit facility (the “Line of Credit”) with the Lenders in an aggregate principal amount at any one time outstanding not in excess of Twenty Million Dollars
($20,000,000) (the “Maximum Line Commitment”), to expire December 1, 2009 (the “Maturity Date”);” and 
 (ii) the definition of Maturity Date appearing in Section 9 of the Loan Agreement is hereby amended by deleting such definition in its entirety, and inserting in lieu thereof the following: 
 “Maturity Date: has the meaning specified in subsection 1.1.” 
  

 1 

 (b) Section 1.2(b) Mechanics of Revolving Credit Loans is hereby deleted in its entirety and
the following is inserted in lieu thereof: 
 (b) Mechanics of Revolving Credit Loans. Each Revolving Credit Loan
shall be made by the Lenders, severally in accordance with their respective Commitments and in such amounts (not in excess of the Maximum Line Commitment) as the Borrower shall request. Revolving Credit Loans shall be effected at the principal
banking office of the Agent at 40 Water Street, Boston, Massachusetts 02109-3661, and shall be made at such times as the Borrower may request upon one (1) Banking Day’s prior notice to the Agent in the case of any borrowing for which
interest is calculated using the Base Rate (collectively, “Base Rate Loans”) and three (3) Banking Days’ prior notice in the case of any borrowing (x) for which interest is calculated using the LIBOR Rate
(collectively, “LIBOR Portions”) or (y) which is borrowing in Eurocurrency. Each borrowing request for the Revolving Credit Loans which are not in Eurocurrency shall be in the form attached hereto as Exhibit E (the
“Borrowing Request”). Each borrowing request for a Eurocurrency Loan (“Eurocurrency Borrowing Request”) shall be in the form required in Section 1.2(d)(2) below. Each Borrowing Request and each Eurocurrency Borrowing
Request may be sent to the Agent by facsimile. The Lenders will use their best efforts to fund requests for Revolving Credit Loans on the Banking Day requested by the Borrower in accordance with the terms hereof. In the event that notwithstanding
its best efforts, the Lenders are unable to fund a requested Revolving Credit Loan on the Banking Day requested by the Borrower in accordance with the terms hereof, the Lenders shall have no liability whatsoever for such failure to fund on the
requested Banking Day and will fund such Revolving Credit Loan (a) on the next Banking Day in the case such Revolving Credit Loan accrues interest based upon the Base Rate or the LIBOR Rate and (b) if possible on the next Banking Day in
the case of Eurocurrency Loans. The Lenders shall make each Revolving Credit Loan which is not a Eurocurrency Loan hereunder by crediting the amount of such Revolving Credit Loan to the Borrower’s operating account (Account No. 8142333)
with the Agent (together with any other account from time to time designated by the Borrower for the purpose of effecting Revolving Credit Loans, the “Operating Account”). The Lenders shall make each Revolving Credit Loan which is a
Eurocurrency Loan hereunder by crediting the amount of such Eurocurrency Loan, in the Eurocurrency requested, to the applicable Eurocurrency demand deposit account with the Agent. 
 (c) Section 1.2 Revolving Credit Loans; Reborrowings; Compliance Certificates is hereby amended by adding the following section: 

(d) Eurocurrency Borrowings: 
 (1) Subject to the terms and conditions set forth herein, the Lenders severally agree to make Eurocurrency Loans, from time to time, to the Borrower as provided in Section 1.2(d)(2), on the applicable
Banking Day requested by the Borrower in accordance with the terms hereof, in an aggregate principal amount that when added to the principal outstanding of all other outstanding Revolving Credit Loans made by such Lender, not to exceed at any time
outstanding such Lender’s Commitment; provided however, that after giving effect to any Eurocurrency Loan, the total principal amount outstanding of all Eurocurrency Loans shall not exceed the Eurocurrency Loan Limit. 

 

 2 

 (2) For each borrowing in Eurocurrency and each continuation of a borrowing in
Eurocurrency the Borrower shall provide to the Agent a Eurocurrency Borrowing Request which shall constitute the Borrower’s irrevocable notice to the Agent and shall be appropriately completed and signed by the chief financial officer or other
senior officer of the Borrower. A Eurocurrency Borrowing Request may not be given by telephone. Each Eurocurrency Borrowing Request must be received by the Agent not later than 11:00 a.m. Boston time. Each borrowing of or continuation of
Eurocurrency Loans shall be in a principal amount of €500,000 or 500,000 Sterling or a whole multiple of €250,000 or 250,000 Sterling in excess thereof. Each Eurocurrency Borrowing Request shall specify (i) whether the Borrower is
requesting a Eurocurrency Loan, or a continuation of a Eurocurrency Loan, (ii) the requested date of the borrowing or continuation, as the case may be, (iii) the principal amount of Eurocurrency Loans to be borrowed or continued,
(iv) the duration of the Eurocurrency Interest Period with respect thereto and (v) the Eurocurrency requested. If the Borrower fails to give a timely Eurocurrency Borrowing Request requesting a continuation, then the applicable
Eurocurrency Loans shall not be continued and at the expiration of the applicable Eurocurrency Interest Period shall become Base Rate Loans. If the Borrower requests a borrowing of, or continuation of, Eurocurrency Loans in any such Eurocurrency
Borrowing Request, but fails to specify a Eurocurrency Interest Period, it will be deemed to have specified a Eurocurrency Interest Period of one month. After giving effect to all Eurocurrency Loans and all continuations thereof, there shall not be
more than three Eurocurrency Interest Periods in effect with request to Eurocurrency Loans. 
 (3) The Borrower may, upon
written notice (“Eurocurrency Notice of Prepayment”) to the Agent, at any time or from time to time voluntarily prepay Eurocurrency Loans, in whole or in part, without premium or penalty, provided that (i) such notice must be
received by the Agent not later than 11:00 a.m. Boston time and shall specify the date and the amount of such prepayment three Banking Days prior to any date of prepayment; and (ii) any prepayment shall be in a principal amount of €500,000
or 500,000 Sterling or a whole multiple of €250,000 or 250,000 Sterling in excess thereof or, if less, the entire principal amount thereof then outstanding; provided, further that that if a Eurocurrency Loan is prepaid on any day
other than the last day of the Eurocurrency Interest Period applicable thereto, the Borrower shall also pay the Eurocurrency Premium together with all other amounts due therefor under Section 2. If any such Eurocurrency Notice of Prepayment is
given, the amount specified in such Eurocurrency Notice of Prepayment shall be due and payable on the date specified therein, together with accrued interest to such date on the amount prepaid and the other amounts required to be paid hereunder at
such time in connection therewith.

 (d) Section 1.4 Interest; Applicable Margins is hereby deleted in its entirety and the
following is inserted in lieu thereof: 
 1.4 Interest; Applicable Margins. 
 (a) The Revolving Credit Loans shall bear interest (computed on the basis of the actual number of days elapsed over a 360-day year) on the unpaid
principal amount thereof until paid in full at the rate or rates per annum determined as follows: 
 (i) The per annum rate
for any portion of the outstanding principal balance of the Revolving Credit Notes which is not then subject to a LIBOR Option and which is not a Eurocurrency Loan shall be equal to the Applicable Base Rate Margin (as hereinafter defined in
subsection 1.4(c)) plus the Base Rate; 
 (ii) The per annum rate for any LIBOR Portion shall be equal to the
Applicable LIBOR Margin (as hereinafter defined in subsection 1.4(c)) plus the LIBOR Rate; and 
 (iii) The per annum rate for
any Eurocurrency Loan shall be equal to the Applicable Eurocurrency Margin (as hereinafter defined in subsection 1.4(c)) plus the Eurocurrency Rate. 
 (b) Interest on any portion of the Revolving Credit Notes (i) accruing based upon the Base Rate shall be payable monthly in arrears on the first day of each month, commencing on the first such date next
succeeding the date of issuance of the Revolving Credit Notes, (ii) accruing based upon the LIBOR Rate shall be payable on the earlier to occur of (x) the last day of the LIBOR Period applicable to such LIBOR Portion or (y) the
90th day of such LIBOR Period, and at maturity (whether by acceleration or otherwise) and (iii) accruing based upon the Eurocurrency Rate shall be payable on the earlier to occur of (x) the last day of the Eurocurrency Interest Period
applicable to such Eurocurrency Loan or (y) the 90th day of such Eurocurrency Interest Period, and at maturity
(whether by acceleration or otherwise). Each change in the rate of interest payable on any portion of the outstanding principal balance of the Revolving Credit Notes which is not then subject to a LIBOR Option and which is not a Eurocurrency Loan
shall take effect simultaneously with the corresponding change in the Base Rate. Notwithstanding anything contained herein or in any other Loan Document to the contrary, in no event shall the amount paid or agreed to be paid by the Borrower as
interest on the Revolving Credit Loans exceed the highest lawful rate permissible under any law applicable thereto. 
 (c) Applicable
Margin. For the purpose of this subsection 1.4, the “Applicable Margin” shall be determined as follows: 
 (i) subject to the provisions of subparagraph (iii) hereof, from and after each Interest Adjustment Date until the next Interest Adjustment Date, the Applicable Margin for Base Rate Revolving Credit Loans (the “Applicable Base
Rate Margin”), for Revolving Credit Loans subject to a LIBOR Option (the “Applicable LIBOR Margin”) and for Eurocurrency Loans (the “Applicable Eurocurrency Margin”) shall be the respective amounts set
forth in the following table opposite the 

  

 4 

 
applicable ratio of outstanding Total Funded Debt to Adjusted EBITDA: 
  

							
	 Ratio of Outstanding Total Funded Debt to Adjusted EBITDA
 (for the most recently concluded period of four consecutive fiscal quarters)
	  	Applicable Base
Rate Margin	 	 	Applicable LIBOR
Margin and
Applicable
Eurocurrency Margin	 
	 Greater than or equal to 1.00:1.00 but less than or equal to 2.00:1.00
	  	0	%	 	2.75	%
	 Less than 1.00:1.00
	  	0	%	 	2.50	%

 (ii) As used herein, the term “Interest Adjustment Date” shall
mean (A) the first day of the first month after the date on which each of the quarterly compliance certificates (together with quarterly unaudited financial statements for such quarter) required to be delivered under subsection 5.1 (the
“Required Financial Statements”) with respect to the then most recently ended quarter were due, if the foregoing table indicates an upward adjustment of the Applicable Margin, or (B) the later of such date or the first day of
the first month after the date that all of the Required Financial Statements for such quarter shall have been received by the Agent, if the foregoing table indicates a downward adjustment of the Applicable Margin. 
 (iii) The determination of the Applicable Margin hereunder as of any Interest Adjustment Date shall be based on unaudited quarterly
financial statements and compliance certificates as provided above, provided, that in the event of any discrepancy between computations based upon any compliance certificates and the related audited financial statements furnished pursuant to
subsection 5.1 (the “Audited Financial Statements”) the computation based upon the Audited Financial Statements shall govern (retroactive to the most recent Interest Adjustment Date). In the event of a retroactive correction in the
determination of the Applicable Margin in favor of the Lenders, the amount of interest thereby overdue and payable by the Borrower shall be paid to the Agent for the account of each Lender in accordance with and proportionate to such Lender’s
Commitment within five (5) Banking Days after the date of such retroactive correction. Notwithstanding any of the foregoing, upon any upward adjustment of the Applicable Margin, there shall be no subsequent downward adjustment of the Applicable
Margin until the first day of the first month after the ratio of outstanding Total Funded Debt to Adjusted EBITDA would result in such downward adjustment as of the end of a subsequent fiscal quarter. Notwithstanding anything to the contrary set
forth in this Agreement, no downward adjustment of the Applicable Margin 

  

 5 

 
shall occur if, at the time such downward adjustment would otherwise be made, there shall exist any Event of Default, provided that such downward
adjustment shall be made on the first day of the first month after the date on which any Event of Default preventing such downward adjustment shall have been cured in accordance with Section 12, assuming that no other Event of Default exists at
the time of such downward adjustment. 
 (e) Section 1.5 Fees (a) Unused Line Fee is hereby amended by adding the
following as a last sentence to such section: 
 “For purposes of such calculation, all Eurocurrency Loans shall be calculated in their
Dollar Equivalent” 
 (f) Section 2 LIBOR Provisions is hereby deleted in its entirety and the following is inserted in lieu
thereof:

Period, multiplied by (ii) the principal amount so prepaid, multiplied by (iii) a fraction, the numerator of which is the number of days remaining in the related Eurocurrency Interest Period and the denominator of which is 360. If the
result of clause (i) is less than or equal to zero, there shall be no Eurocurrency Premium. 
  

 6 

 “Eurocurrency Base Rate”: for any Eurocurrency Interest Period with
respect to any Eurocurrency Loan: 
 (a) the rate per annum equal to the rate determined by the Agent to be the offered rate
that appears on page 3750 of the Telerate screen (or any successor thereto) (or such other page of the Telerate as is customary for the Euro or Sterling) that displays an average British Bankers Association Interest Settlement Rate for deposits in
Euro (for delivery on the first day of such Interest Period) if a Euro denominated loan and for deposits in Sterling (for delivery on the first day of such Interest Period) if a Sterling denominated loan with a term equivalent to such Interest

Eurocurrency Interest Period, determined as of approximately 11:00 a.m., London time, two (2) Banking Days prior to the first day of such Eurocurrency Interest Period for a Euro denominated loan and on the first day of such Eurocurrency
Interest Period if a Sterling denominated loan, or 
 (c) if the rates referenced in the preceding clauses (a) and

approximate amount of the Eurocurrency Loan being made, continued or converted by the Agent and with a term equivalent to such Eurocurrency Interest Period that would be offered to the Agent for the applicable Eurocurrency in the London interbank
Eurocurrency market at its request at approximately 11:00 a.m., London time, two (2) Banking Days prior to such Eurocurrency Interest Period for a Euro denominated loan and on the first day of such Interest Period if a Sterling denominated

Authority having jurisdiction with respect thereto) for determining the maximum reserve requirement (including any emergency, supplemental or other marginal reserve requirement) with respect to eurocurrency funding (currently referred to as
“Eurocurrency liabilities”). The Eurocurrency Rate for each outstanding Eurocurrency Loan shall each be adjusted automatically as of the effective date of any change in the Eurocurrency Reserve Percentage. The determination of the
Eurocurrency Reserve Percentage by the Agent shall be conclusive in the absence of manifest error. 
 “Eurocurrency
Interest Period”: means as to each Eurocurrency Loan the period commencing on the date such Eurocurrency Loan is disbursed or converted to or continued as a Eurocurrency Loan, and ending on the date 30, 60 or 90 days thereafter, as selected

 (i) any Eurocurrency Interest Period that
would otherwise end on a day that is not a Banking Day shall be extended to the next succeeding Banking Day unless, in the case of a Eurocurrency Loan such Banking Day falls in another calendar month, in which case such Eurocurrency Interest Period
shall end on the next preceding Banking Day; 
 (ii) any Eurocurrency Interest Period pertaining to a Eurocurrency Loan that
begins on the last Banking Day of a calendar month (or on a day for which there is no numerically corresponding day in the calendar month at the end of such Eurocurrency Interest Period) shall end on the last Banking Day of the calendar month at the

 “Legal Requirement”: any requirement imposed upon the Agent or any Lender by any law of the United States of America or
the United Kingdom or by any regulation, order, interpretation, ruling or official directive (whether or not having the force of law) of the Board, the Bank of England or any other board, central bank or governmental or administrative agency,
institution or authority of the United States of America, the United Kingdom or any political subdivision of either thereof.

Requirement (i) to be paid by the Lenders and/or (ii) to be withheld or deducted from any payment otherwise required hereby to be made by the Borrower to the Lenders, provided that the term “Lender Tax” shall not
include any taxes imposed upon the net 

  

 8 

 
income of the Lenders by the United States of America, the United Kingdom, any Participating Member States, or any political subdivision of any of the

or any portion of the principal amount of the Loans based on a LIBOR Rate. 
 “LIBOR Period”: any period,
selected as provided below in this Section 2, of 30, 60 or 90 days, commencing on any Banking Day; provided, however, that no LIBOR Period with respect to any LIBOR Portion shall extend beyond the Maturity Date. At the commencement of
the LIBOR Period, the Agent shall notify the Borrower of the termination date of such LIBOR Period. If any LIBOR Period so selected would otherwise end on a date which is not a Banking Day, such LIBOR Period shall instead end on the next preceding
or succeeding Banking Day as determined by the Agent in accordance with the then current banking practice in London. Each determination by the Agent of any LIBOR Period shall, in the absence of manifest error, be conclusive, and at the
Borrower’s request the Agent shall demonstrate the basis for such determination. 
 “LIBOR Portion”:
that portion of the Revolving Credit Loans specified in a LIBOR Request (including any portion of such Revolving Credit Loans which are being borrowed by the Borrower concurrently with such LIBOR Request) which is not less than $100,000 and is an
integral multiple of $100,000, and which, as of the date of the LIBOR Request specifying such LIBOR Portion, has met the conditions for basing interest on the LIBOR Rate in subsection 2.3 hereof and the LIBOR Period of which has commenced and not
terminated. 
 “LIBOR Premium”: With respect to the prepayment of any LIBOR Portion of any Revolving Credit
Loans prior to the end of the applicable LIBOR Period, an amount equal to the product of (i) the excess, if any, of the original LIBOR Rate on the amount so prepaid over the LIBOR Rate of interest on Eurodollar deposits in effect on the date of
such prepayment and having a maturity date approximating the last Banking Day of the applicable LIBOR Period, multiplied by (ii) the principal amount so prepaid, multiplied by (iii) a fraction, the numerator of which is the number of days
remaining in the related LIBOR Period and the denominator of which is 360. If the result of clause (i) is less than or equal to zero, there shall be no LIBOR Premium. 
 “LIBOR Rate”: with respect to any LIBOR Portion for the related LIBOR Period, an interest rate per annum (rounded
upwards, if necessary, to the next higher 1/8 of 1%) equal to the product of (a) the Base LIBOR Rate (as hereinafter defined) and (b) Statutory Reserves. For purposes of this definition, the term “Base LIBOR Rate” shall
mean the rate (rounded to the nearest 1/8 of 1% or, if there is no nearest 1/8 of 1%, the next higher 1/8 of 1%) at which deposits of US dollars approximately equal in principal amount to the LIBOR Portion and for a maturity equal to the applicable
LIBOR Period are offered to the Agent in the London interbank foreign currency deposits market at approximately 11:00 a.m., London time (or, if such rate is not then offered to the Agent, at the rate (rounded as provided above) at which deposits of
US dollars approximately equal in 

  

 9 

 
principal amount to the LIBOR Portion and for a maturity equal to the applicable LIBOR Period are offered on the Telerate (page 3750) or any successor page),
three (3) Banking Days prior to the commencement of such LIBOR Period, for delivery on the first day of such LIBOR Period. Each determination by the Agent of any LIBOR Rate shall, in the absence of manifest error, be conclusive, and at the
Borrower’s request, the Agent shall demonstrate the basis for such determination. Promptly upon determining the LIBOR Rate for an applicable LIBOR Period, the Agent shall give written notice of such LIBOR Rate to the Borrower and, if requested
by the Borrower, shall provide reasonable details demonstrating the basis for such LIBOR Rate determination. 
 “LIBOR
Request”: notice in writing (or by telephonic communication confirmed by telex, telecopy or other facsimile transmission on the same day as the telephone request) from the Borrower to the Agent requesting that interest on a LIBOR Portion be
based on the LIBOR Rate, specifying: (i) the first day of the LIBOR Period, (ii) the length of the LIBOR Period consistent with the definition of that term, and (iii) a dollar amount of the LIBOR Portion consistent with the definition
of that term. 
 “Statutory Reserves”: a fraction (expressed as a decimal), the numerator of which is the
number one and the denominator of which is the number one minus the aggregate of the maximum reserve percentages (including, without limitation, any marginal, special, emergency or supplemental reserves), expressed as a decimal, established by the
Board and any other banking authority to which any Lender is subject for Eurocurrency Liabilities (as defined in Regulation D of the Board). Such reserve percentages shall include, without limitation, those imposed under such Regulation D. LIBOR
Portions of the Revolving Credit Loans shall be deemed to constitute Eurocurrency Liabilities and as such shall be deemed to be subject to such reserve requirements without benefit of or credit for proration, exceptions or offsets which may be
available from time to time to the Lenders under such Regulation D. Statutory Reserves shall be adjusted automatically on and as of the effective date of any change in any reserve percentage. 
 2.3 Conditions for Basing Interest on the LIBOR Rate or the Eurocurrency Rate. Upon the condition that: 
 (a) The Agent shall have received a LIBOR Request or a Eurocurrency Borrowing Request, as applicable, from the Borrower, at least three (3) Banking
Days prior to the first day of the applicable LIBOR Period or the Eurocurrency Interest Period requested, as applicable; 
 (b) There shall
have occurred no change in applicable law which would make it unlawful for the Agent to obtain deposits of US dollars in the London interbank foreign currency deposits market with respect to any request for a LIBOR Portion or to obtain Eurocurrency
in any applicable Eurocurrency market with respect to any Eurocurrency Loan; 
 (c) As of the date of the LIBOR Request or the Eurocurrency
Borrowing Request, as applicable, and the first day of the LIBOR Period or the Eurocurrency Interest Period, as applicable, there shall exist no Default or Event of Default; and 
  

 10 

 (d) The Agent shall not have determined in good faith that it is unable to determine the LIBOR Rate or
the Eurocurrency Rate, as applicable, in respect of the requested LIBOR Period or in respect of the requested Eurocurrency Interest Period, as applicable, or that it is unable to obtain deposits of US dollars in the London interbank foreign currency
deposits market or obtain Eurocurrency, as applicable, in the applicable amounts and for the requested LIBOR Period or the Eurocurrency Interest Period; then the interest on the LIBOR Portion specified in the LIBOR Request during the LIBOR Period
specified in the LIBOR Request will be based on the applicable LIBOR Rate or the interest on the Eurocurrency Loan specified in the Eurocurrency Borrowing Request during the Eurocurrency Interest Period specified in the Eurocurrency Borrowing
Request will be based on the applicable Eurocurrency Rate. 
 2.4 Indemnification for Funding and Other Losses. Each LIBOR Request and
each Eurocurrency Borrowing Request shall be irrevocable and binding on the Borrower, provided that the Borrower may specify in any such LIBOR Request a maximum LIBOR Rate which they will accept for the related LIBOR Period and the LIBOR
Option elected in such LIBOR Request shall not become effective if the applicable LIBOR Rate determined by the Agent shall exceed such specified maximum. Without limiting the generality of subsection 2.5, the Borrower hereby agrees to indemnify the
Agent and Lenders against any loss or expense incurred by the Agent or any Lender as a result of any failure on the part of the Borrower (so long as such failure is through no fault of the Agent or Lenders) to fulfill, on or before the date
specified in any LIBOR Request or any Eurocurrency Borrowing Request, as applicable, the applicable conditions set forth in this Agreement, including, without limitation, any loss (including loss of anticipated profits) or expense incurred by reason
of the liquidation of redeployment of deposits or other funds acquired by the Agent or any Lender to fund or maintain the requested LIBOR Portion or any Eurocurrency Loan when interest on such LIBOR Portion or Eurocurrency Loan, as applicable, as a
result of such failure on the part of the Borrower, is not based on the applicable LIBOR Rate or Eurocurrency Rate, as applicable, for the requested LIBOR Period or Eurocurrency Interest Period. 
 2.5 Change in Applicable Laws, Regulations, etc. If any Legal Requirement shall make it unlawful for any Lender to fund through the purchase of US
dollar deposits any LIBOR Portion or to fund by obtaining the applicable Eurocurrency, or otherwise to give effect to its obligations as contemplated hereby, or shall impose on any Lender any costs based on or measured by the excess above a
specified level of the amount of a category of deposits or other liabilities of any Lender which includes deposits by reference to which the LIBOR Rate or the Eurocurrency Rate is determined as provided herein or a category of extensions of credit
or other assets of any Lender which includes any LIBOR Portion or any Eurocurrency Loan or shall impose on any Lender any restrictions on the amount of such a category of liabilities or assets which such Lender may hold, (a) the Lenders by
notice thereof to the Borrower may terminate the LIBOR Option or the Borrower’s ability to borrow Eurocurrency, as applicable, (b) any LIBOR Portion or any Eurocurrency Loan subject thereto shall immediately bear interest thereafter at the
rate provided for (with respect to Revolving Credit Loans not subject to a LIBOR Option or which is not a Eurocurrency Loan) in subsection 1.4, and (c) the Borrower shall indemnify the Lenders against any loss, penalty or expense incurred by
the Lenders by reason of the liquidation or redeployment of deposits or other funds acquired by the Lenders, to fund or maintain such LIBOR Portion or such Eurocurrency Loan, as applicable, if and to 

  

 11 

 
the extent such loss, penalty or expense is caused by the nature of the business of the Borrower and its Subsidiaries or the locations and jurisdictions
where the Borrower or its Subsidiaries are operating. Promptly after becoming aware of the occurrence of any event or condition described in this subsection 2.5, the affected Lender(s) shall give written notice thereof to the Borrower and shall
provide reasonable details setting forth the basis for its determination and such other information as shall be reasonably requested by Borrower to confirm the affected Lenders’ determination and computations. A certificate of an officer of
such Lender setting forth the amount of such loss, penalty or expense, and the basis therefor shall, in the absence of manifest error, be conclusive. 
 2.6 Lender Taxes. It is the understanding of the Borrower and the Lenders that the Lenders shall receive payments of amounts of principal of and interest on the Notes (including but not limited to interest with
respect to the LIBOR Portions from time to time subject to a LIBOR Option or any Eurocurrency Loan) free and clear of, and without deduction for, any Lender Taxes. If (a) any Lender shall be subject to any such Lender Tax in respect of any such
LIBOR Portion or Eurocurrency Loan or part thereof or (b) the Borrower shall be required to withhold or deduct any such Lender Tax from any such amount, and (c) such Lender Tax shall not have existed as of the date of the applicable LIBOR
Request or Eurocurrency Borrowing Request, the LIBOR Rate applicable to such LIBOR Portion and the Eurocurrency Rate applicable to such Eurocurrency Loan, as applicable, shall be adjusted by any such Lender to reflect all additional costs incurred
by such Lender in connection with the payment by such Lender or the withholding by the Borrower of such Lender Tax and the Borrower shall provide each such Lender with a statement detailing the amount of any such Lender Tax actually paid by the
Borrower. Determination by any affected Lender of the amount of such costs shall, in the absence of manifest error, be conclusive. Promptly upon obtaining knowledge of any such circumstance set forth above, the Lender shall give written notice of
such determination to the Borrower and shall provide reasonable details and facts demonstrating the basis for its determination and shall provide such other information as shall be reasonably requested by the Borrower to permit the Borrower to
confirm Lender’s computations and determination. If after any such adjustment, any part of any Lender Tax paid by a Lender is subsequently recovered by such Lender, the Lender shall reimburse the Borrower to the extent of the amount so
recovered. A certificate of an officer of the Lender setting forth the amount of such recovery and the basis therefor shall, in the absence of manifest error, be conclusive, and at the Borrower’s request, the Lender shall demonstrate the basis
of such determination. 
 (g) Section 3.11 of the Loan Agreement is hereby amended by deleting the following sentence in its entirety:

 17 

 
right, power, or remedy of the Agent or any Lender under the Loan Agreement or any other Loan Document, as in effect prior to the date hereof. Each of the
Borrower and each Subsidiary thereof hereby ratifies and confirms in all respects all of its obligations and any prior grant of a security interest under the Loan Agreement (as amended hereby) and the other Loan Documents to which it is a party.

 6. No Novation; Entire Agreement. This Second Amendment evidences solely the amendment of the terms and provisions of the
obligations of the Borrower and its Subsidiaries under the Loan Documents and is not a novation or discharge thereof. There are no other understandings, express or implied, among the Borrower, its Subsidiaries, the Agent and the Lenders regarding

“hereof” or words of like import referring to the Loan Agreement, and each reference in the other Loan Documents to “the Loan Agreement”, “thereunder”, “therein”, “thereof” or words of like import
referring to the Loan Agreement, shall mean and be a reference to the Loan Agreement as modified and amended hereby and by the First Amendment. 
 10. Limited Waiver. Section 5.2 of the Loan Agreement requires the Borrower to, among other things, maintain the existence and business of each of its Subsidiaries. The Borrower permitted the dissolution of its Subsidiary,
Genomic Solutions KK (“Genomic”) which action caused an Event of Default to occur. The Agent and the Lenders hereby waive the occurrence of the Event of Default which arose from the dissolution of Genomic. By the Agent and the Lenders
providing the foregoing waiver, they are not agreeing to provide any waivers for any other Event of Default in the future.
