 Promise to Pay. On or before January 31, 2010 (the “Maturity Date”), the undersigned,
CECO FILTERS, INC., a Delaware corporation, NEW BUSCH CO., INC., a Delaware corporation, THE KIRK & BLUM MANUFACTURING COMPANY, an Ohio corporation, KBD/TECHNIC, INC., an Indiana corporation, CECOAIRE, INC., a Delaware corporation, CECO
ABATEMENT SYSTEMS, INC., a Delaware corporation, H.M. WHITE, INC., a Delaware corporation, EFFOX INC., formerly known as CECO ACQUISITION CORP., a Delaware corporation, GMD ENVIRONMENTAL TECHNOLOGIES, INC., formerly known as GMD ACQUISITION CORP., a
Delaware corporation, and FKI ACQUISITION CORP., a Delaware corporation (each, a “Borrower”, and, collectively, the “Borrowers”), for value received, hereby jointly and severally promise to pay to the order of FIFTH
THIRD BANK, an Ohio banking corporation (together with its successors and assigns, “Lender”), at 38 Fountain Square Plaza, MD #10AT63, Cincinnati, Ohio 45263, or such other address as Lender may provide from time to time, the sum of
THIRTY MILLION AND 00/100 Dollars ($30,000,000), plus interest as provided herein, or so much thereof as is loaned by Lender to Borrowers as Revolving Loans or for which credit is extended by Lender as a Letter of Credit pursuant to the Credit
Agreement among Lender, Borrowers, and certain of Borrowers’ affiliates dated as of December 29, 2005, as amended by the First Amendment to Credit Agreement dated as of June 8, 2006, the Second Amendment to Credit Agreement dated as
of February 28, 2007 and the Third Amendment to Credit Agreement dated as of even date herewith (as the same may be further amended, renewed, consolidated, restated or replaced from time to time, the “Credit Agreement”). The
outstanding balance of this Third Amended and Restated Revolving Credit Promissory Note (this “Note”) shall appear on supplemental bank records and is not necessarily the face amount of this Note, which record shall evidence the
balance due pursuant to this Note at any time. As used herein, “Local Time” means the time at the office of Lender specified in this Note. 
 This Note, and any request by Borrowers from time to time for an advance of a specified principal amount hereunder, shall be subject to the terms and conditions of the Credit Agreement. Capitalized terms used herein which are not otherwise
defined in this Note shall have the meanings set forth in the Credit Agreement. This Note is entitled to the benefits and security of the Credit Agreement, including, without limitation, acceleration upon the terms provided therein, and of the other
Loan Documents. 

 The entire unpaid principal balance of this Note, together with all accrued and unpaid interest and any other charges,
advances and fees, if any, outstanding hereunder, shall be due and payable in full on the earlier of the Maturity Date or upon acceleration of the Indebtedness evidenced by this Note, notwithstanding any other inconsistent or contradictory
provisions contained in this Note. 
 Upon the occurrence and during the continuance of any Event of Default, the entire unpaid principal balance of this
Note, together with all accrued but unpaid interest, and all other Obligations, shall, at Lender’s option, become immediately due and payable, except that if there occurs an Event of Default of the type described in Sections 6.1(d),
6.1(e), or 6.1(j) of the Credit Agreement, the entire unpaid principal balance of this Note, together with all accrued but unpaid interest, and all other Obligations shall become automatically and immediately due and payable without
notice, which Borrowers hereby waive. 
 Interest. Principal amounts outstanding under this Note shall bear interest commencing on the date of the
first advance hereunder at the rate or rates per annum set forth below, which rate or rates shall be designated by Borrowers as more fully set forth herein (the “Interest Rate”). At any time and from time to time during the term of
this Note, so long as no Event of Default has occurred and is continuing and so long as such outstanding principal amounts hereunder are not then subject to a LIBOR Election, Borrowers may exercise their right to adjust the Interest Rate on amounts
of principal outstanding under this Note to one of the rates set forth below upon notice to Lender as set forth below; provided, however, that once the Interest Rate accruing against any amounts outstanding hereunder is adjusted to a LIBOR
Rate for a particular LIBOR Interest Period, Borrowers may not elect to adjust such Interest Rate to a different Interest Rate until the expiration of such LIBOR Interest Period. 
 (a) LIBOR Rate. Upon telephonic notice to Lender by 10:00 a.m. Local Time given at least two Business Days prior to the beginning of a LIBOR Interest Period, Borrowers may, subject to the terms of this Note,
elect to have advances under this Note bear interest at a rate per annum equal to the LIBOR Rate (as defined herein) plus the Applicable LIBOR Rate Margin (as defined herein) (a “LIBOR Election”). The “LIBOR Rate”
is the rate of interest (rounded upwards, if necessary, to the next 1/8 of 1% and adjusted for reserves if Lender is required to maintain reserves with respect to relevant advances) fixed by the British Bankers’ Association at 11:00 a.m.,
London, England time, relating to quotations for the one month, two month, or three month London InterBank Offered Rates, as selected by Borrowers in their LIBOR Election, on U.S. Dollar deposits as published on Bloomberg LP, or, if no longer
provided by Bloomberg LP, such rate as shall be determined in good faith by Lender from such sources as Lender shall determine to be comparable to Bloomberg LP (or any successor) as determined by Lender at approximately 10:00 a.m. Local Time on the
date of request by Borrowers. Each determination by Lender of the LIBOR Rate shall be conclusive in the absence of manifest error. Interest accruing based on the LIBOR Rate shall be: (i) calculated based on a 360-day year and charged for the
actual number of days elapsed and (ii) payable in arrears on the last day of the applicable LIBOR Interest Period. The Interest Rate applicable to a particular LIBOR Election shall remain at the rate elected for the remainder of the subject
LIBOR Interest Period. 
  

 -2- 

 The “LIBOR Interest Period” for each advance bearing interest with respect to the LIBOR Rate (each such
advance, a “LIBOR Rate Loan”) is a period of one month, two months, or three months, at Borrowers’ election, which period shall commence on a Business Day selected by Borrowers subject to the terms of this Note. If a LIBOR
Interest Period would otherwise end on a day that is not a Business Day, such LIBOR Interest Period shall end on the next succeeding Business Day; provided that, if the next succeeding Business Day falls in a new month, such LIBOR Interest
Period shall end on the immediately preceding Business Day. 
 In addition, notwithstanding anything herein contained to the contrary, if, prior to or during
any period with respect to any LIBOR Election, any change in any law, regulation or official directive, or in the interpretation thereof, by any governmental body charged with the administration thereof, shall make it unlawful for Lender to fund or
maintain its funding in Eurodollars of any portion of the advance subject to the LIBOR Rate or otherwise to give effect to Lender’s obligations as contemplated hereby: (i) Lender may, by written notice to Borrowers, declare Lender’s
obligations to make, convert into, continue or maintain LIBOR Rate Loans to be terminated forthwith, and (ii) the LIBOR Rate with respect to Lender shall forthwith cease to be in effect, and interest shall from and after such date be calculated
at the Prime Rate as if a Prime Rate Election had been made, and interest shall be paid, in arrears, on the first (1st) day of each calendar month. Borrowers hereby agree to reimburse and indemnify Lender from all increased costs or fees
incurred by Lender subsequent to the date hereof relating to the offering of rates of interest based upon the LIBOR Rate. In addition, notwithstanding anything herein contained to the contrary, if, prior to or during any period with respect to any
LIBOR Election, any change in any law, regulation or official directive, or in the interpretation thereof, by any governmental body charged with the administration thereof, shall: 
  

	 	(i)	increase the cost to Lender, by an amount which Lender deems to be material, of making, converting into, continuing or maintaining LIBOR Rate Loans, or to reduce any amount
receivable hereunder in respect thereof, or 

  

	 	(ii)	have the effect of reducing the rate of return on Lender’s capital as a consequence of its obligations hereunder to a level below that which Lender could have achieved but for
such change by an amount deemed by Lender to be material, 

 then, in any such case, after submission by Lender to Borrowers of a written
request therefor, Borrowers shall pay Lender any additional amounts necessary to compensate Lender for such increased cost or reduction. Lender agrees that, upon the occurrence of any event giving rise to the operation of this paragraph, it will use
reasonable efforts to designate another lending office (if possible) for any LIBOR Rate Loans affected by such event with the object of avoiding the consequences of such event; provided, that no such designation shall be required unless such
designation can be made on terms that, in the reasonable judgment of Lender, cause Lender and its lending office(s) to suffer no material economic, legal or regulatory disadvantage. A certificate of Lender setting forth the amount or amounts
necessary to compensate Lender as specified in this paragraph and delivered to Borrowers shall be conclusive absent manifest error. Borrowers shall pay Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

  

 -3- 

 Borrowers’ right to make a LIBOR Election shall be terminated automatically if Lender, by telephonic notice, shall
notify Borrowers that Eurodollar deposits with a maturity corresponding to the maturity of the LIBOR Interest Period, in an amount equal to the advances to be subject to the LIBOR Election are not readily available in the London Inter-Bank Offered
Rate Market, or that, by reason of circumstances affecting the London Inter-Bank Offered Rate Market, adequate and reasonable methods do not exist for ascertaining the rate of interest applicable to such deposits for the proposed LIBOR Interest
Period. In such event, amounts outstanding hereunder shall bear interest at the Prime Rate as if a Prime Rate Election had been made or at such other rate of interest as may be agreed to between Lender and Borrowers. 
 If any amount as to which a LIBOR Election is in effect is repaid on a day other than the last day of the applicable LIBOR Interest Period, or becomes payable on a day
other than the last day of the applicable LIBOR Interest Period due to acceleration or otherwise, Borrowers, whether or not a debtor in a proceeding under Title 11, United States Code, shall pay, on demand by Lender, such amount (as determined by
Lender) as is required to compensate Lender for any losses, costs or expenses (“LIBOR Breakage Fee”), which Lender may incur as a result of such payment or acceleration, including, without limitation, any loss, cost or expense
(including loss of profit) incurred by reason of liquidation or reemployment of deposits or other funds acquired by Lender to fund or maintain such amount bearing interest at the applicable LIBOR Rate. A certificate of Lender setting forth the
amount or amounts necessary to compensate Lender as specified in this paragraph and delivered to Borrowers shall be conclusive absent manifest error. 
 (b)
Prime Rate. Upon telephonic notice by Borrowers to Lender by 10:00 a.m. Local Time, Borrowers may elect to have all or any portion of the Revolving Loans outstanding hereunder (provided such amounts are not then subject to a LIBOR Election),
bear interest at a floating rate equal to the rate of interest per annum established from time to time by Lender at its principal office as its “Prime Rate” plus the Applicable Prime Rate Margin (as defined below) (the “Prime Rate
Election”) (it being understood by Borrowers that such Prime Rate is established for reference purposes only and not as Lender’s best loan rate). Any adjustment in the Interest Rate resulting from a change in Lender’s Prime Rate
shall become effective as of the opening of business on the date of each change (or if not a Business Day, the beginning of the day). Interest on the principal amount subject to a Prime Rate Election shall be calculated based on a 360-day year and
charged for the actual number of days elapsed, and shall be payable in arrears on the first day of each calendar month. 
 On or before the date that is two
Business Days before the making of any LIBOR Rate Loan, and on or before the date which is two Business Days prior to the expiration of any applicable LIBOR Interest Period, Borrowers shall notify Lender of each of the following: (a) the LIBOR
Interest Period Borrowers have elected regarding any such LIBOR Rate Loan or any continuation of a LIBOR Election with respect to a LIBOR Rate Loan, (b) the amount of each such LIBOR Rate Loan or continuation, and (c) the commencement date
of each LIBOR Interest Period. Borrowers may have LIBOR Rate Loans in minimum amounts of $1,000,000 (and integral multiples of $100,000) and such LIBOR Rate Loans may bear interest at the applicable Interest Rate for different LIBOR Interest Periods
so long as (i) the last day of any LIBOR Interest Period does not exceed the Maturity Date hereof; (ii) no LIBOR Election with respect to any LIBOR Rate Loan commences prior to the expiration of the applicable LIBOR Interest Period in
effect with respect to such LIBOR Rate Loan; and (iii) at no time may Borrowers have more than three outstanding LIBOR Rate Loans, in the aggregate, under all of their Notes and one Prime Rate Election under this Note. If, at any time during
the term hereof, 

  

 -4- 

 
Borrowers fail to designate a LIBOR Interest Period or if Borrowers have not elected another LIBOR Interest Period in accordance with this Note at least two
Business Days prior to the expiration of the LIBOR Interest Period then in effect, Lender may assume that Borrowers have elected a Prime Rate Election. 
 (c) Pricing Grid. As used herein, the terms “Applicable Prime Rate Margin” and “Applicable LIBOR Rate Margin” (hereafter sometimes collectively referred to as the “Applicable
Margins”) mean, as of any date, the applicable per annum rate shown in the applicable column in the table below based on the then applicable Fixed Charge Coverage Ratio. “Fixed Charge Coverage Ratio” has the meaning given
in the Credit Agreement. 
  

							
	 Pricing Grid
Level
	  	 Fixed Charge Coverage Ratio
	  	Applicable Prime Rate
Margin	 	Applicable LIBOR Rate
Margin
	 Level 1
	  	£ 1.50 to 1.0	  	0.25%	 	2.50%
	 Level 2
	  	> 1.50 to 1.0 and £ 2.0 to 1.0	  	0.0%	 	2.25%
	 Level 3
	  	> 2.0 to 1.0	  	0.0%	 	2.00%

 For purposes of determining the Applicable Margins: the Fixed Charge Coverage Ratio will, on and after the First
Pricing Grid Determination Date, be determined (i) as of the end of each Fiscal Year ending on and after the First Pricing Grid Determination Date (each such date being a “Determination Date”) and (ii) in the same manner
used to determine the Fixed Charge Coverage Ratio set forth in Section 5.10 of the Credit Agreement. The “First Pricing Grid Determination Date” will be December 31, 2007. On Lender’s receipt of the financial
statements and Compliance Certificate required to be delivered to Lender pursuant to Sections 4.3(b) and 4.3(d) of the Credit Agreement for the Fiscal Year then ended, the Interest Rate will be subject to adjustment in accordance with
the table set forth above in this subparagraph (c) based on the then Fixed Charge Coverage Ratio for such Fiscal Year then ended so long as no Event of Default is existing as of the applicable effective date of adjustment. The foregoing
adjustment, if applicable, will become effective for LIBOR Elections made with respect to the Revolving Loans, the unpaid principal balance of the Revolving Loans subject to a Prime Rate Election and other outstanding Obligations related to the
Revolving Loans and the Letter of Credit Obligations due with respect to Letters of Credit issued or renewed, on and after the first day of the first calendar month following delivery to Lender of the financial statements and Compliance Certificate
required to be delivered to Lender pursuant to Sections 4.3(b) and 4.3(d) of the Credit Agreement for the Fiscal Year then ended until the next succeeding effective date of adjustment pursuant to this subparagraph (c). Each of the
financial statements and Compliance Certificate required to be delivered to Lender must be delivered to Lender in compliance with Section 4.3 of the Credit Agreement. If, however, either the financial statements or the Compliance
Certificate required to be delivered to Lender pursuant to Sections 4.3(b) and 4.3(d) of the Credit Agreement have not been delivered in accordance with Section 4.3 of the Credit Agreement, then, at Lender’s option,
commencing on the date upon which such financial statements or Compliance Certificate should have been delivered in accordance with Section 4.3 of the Credit Agreement and continuing until such financial statements or Compliance
Certificate are actually delivered in accordance with Section 4.3 of the Credit Agreement, it shall be assumed for purposes of determining the Applicable Margins, that the Fixed Charge Coverage Ratio was £
1.50 to 1.0 and the pricing associated therewith (i.e., Pricing Grid Level 1) will be applicable on the then applicable Determination Date. As of the Effective Date of this Note, the Applicable Prime Rate Margin is 0.0% per annum and the
Applicable LIBOR Rate Margin is 2.00% (i.e., Pricing Grid Level 3, notwithstanding the Loan Parties’ actual Fixed Charge Coverage Ratio prior to and as of such Effective Date). 
  

 -5- 

 Maximum Rate. In no event shall the Interest Rate provided for hereunder, together with all fees and charges as
provided for herein or in any other Loan Document which are treated as interest under applicable law (collectively with interest, the “Charges”), exceed the maximum rate legally chargeable by Lender under applicable law for loans of
the type provided for hereunder (the “Maximum Rate”). If, in any month, the Charges, absent such limitation, would have exceeded the Maximum Rate, then the Charges for that month shall be at the Maximum Rate, and, if in future
months, such Charges would otherwise be less than the Maximum Rate, then such Charges shall remain at the Maximum Rate until such time as the amount of Charges paid hereunder and under the other Loan Documents equals the amount of Charges which
would have been paid if the same had not been limited by the Maximum Rate. In the event that, upon payment in full of the Obligations, the total amount of Charges paid or accrued in respect of the Indebtedness evidenced by this Note and the other
Obligations is less than the total amount of Charges which would, but for this paragraph, have been paid or accrued if the Charges otherwise set forth in this Note and in the other Loan Documents had at all times been in effect, then Borrowers
shall, to the extent permitted by applicable law, pay to Lender an amount equal to the difference between: (a) the lesser of: (i) the amount of Charges which would have been charged if the Maximum Rate had, at all times, been in effect or
(ii) the amount of Charges which would have accrued had such Charges otherwise provided for in this Note and in the other Loan Documents at all times been in effect and (b) the amount of Charges actually paid or accrued in respect of the
Indebtedness evidenced by this Note or any of the other Loan Documents. In the event that a court of competent jurisdiction determines that Lender has received any Charges in respect of the Indebtedness evidenced by this Note and the other Loan
Documents in excess of the Maximum Rate, such excess shall be deemed received on account of, and shall automatically be applied to reduce, the Obligations owed to Lender other than any Charges, in the inverse order of maturity, and if there are no
Obligations to Lender outstanding, Lender shall refund to Borrowers (or to such Person to which Lender is directed by a court of competent jurisdiction) such excess. 
 Use of Proceeds. Borrowers certify that the proceeds of the Revolving Loans will be used for the purposes set forth in the Credit Agreement. 
 Default Rate; Fees. To the extent any payment is not made within 15 days after the date when due under this Note and, at or before the end of such 15-day period, there was insufficient Revolving Loan
Availability to charge the full amount of such payment to the loan account with Lender as an advance of the Revolving Loans, Borrowers shall pay to Lender a late payment fee equal to two percent (2%) of that portion of any payment not paid when
due (whether by maturity, acceleration or otherwise). After the occurrence and during the continuation of an Event of Default, Borrowers agree that Lender may, without notice, increase the Interest Rate by an additional 2.0% per annum (the
“Default Rate”); provided that this paragraph shall not be deemed to constitute a waiver of any Event of Default or an agreement by Lender to permit any late payments whatsoever. 
  

 -6- 

 Prepayment. Borrowers will make each mandatory prepayment of the principal of this Note required by the Credit
Agreement. Subject to Section 6.4(b) of the Credit Agreement, Borrowers may prepay all of this Note at any time; provided that if any prepayment results in any LIBOR Breakage Fee or a Termination Fee (as defined in
Section 6.4(b) of the Credit Agreement), Borrowers will pay such LIBOR Breakage Fee due in accordance with this Note and, as applicable, the Termination Fee. 
 Entire Agreement. Borrowers agree that there are no conditions or understandings which are not expressed in this Note or the other Loan Documents. 
 Severability. If any provision of this Note is held to be invalid by a court of competent jurisdiction in a final order, the invalid provision will, subject to the provisions of this Note with respect to the
Maximum Rate, be deemed severed from this Note and shall not affect any part of the remainder of the provisions of this Note. 
 Joint Obligations.
All of the obligations of Borrowers hereunder are joint, several and primary. No Borrower shall be or be deemed to be an accommodation party with respect to this Note. 
 Assignment. Borrowers agree not to assign any of any Borrower’s rights, remedies or obligations described in this Note without the prior written consent of Lender, which consent may be withheld in
Lender’s sole discretion. Borrowers agree that Lender may assign some or all of its rights and remedies described in this Note without prior consent from Borrowers, provided that Lender will promptly notify Borrowers of a total
assignment of this Note. 
 Prior Note. This Note is issued, not as a refinancing or refunding of or payment toward, but as a continuation of, the
Obligations of Borrowers to Lender pursuant to that certain Second Amended and Restated Revolving Credit Promissory Note dated as of February 28, 2007 in the principal amount of $20,000,000 (as amended, and together with all prior amendments
thereto or restatements thereof, the “Prior Note”), together with any and all additional Revolving Loans incurred under this Note. Accordingly, this Note shall not be construed as a novation or extinguishment of the Obligations
arising under the Prior Note, and its issuance shall not affect the priority of any Lien granted in connection with the Prior Note. Interest accrued under the Prior Note prior to the date of this Note remains accrued and unpaid under this Note and
does not constitute any part of the principal amount of the Indebtedness evidenced hereby. The entire unpaid principal balance created or existing under, pursuant to, as a result of, or arising out of, the Prior Note shall, together with any and all
additional Revolving Loans incurred under this Note, continue in existence under this Note, which Obligations Borrowers acknowledge, affirm, and confirm to Lender. The Indebtedness evidenced by this Note will continue to be secured by all of the
collateral and other security granted to Lender under the Prior Note and the other Loan Documents. 
 Modification; Waiver of Lender. The modification
or waiver of any of Borrowers’ obligations or Lender’s rights under this Note must be contained in a writing signed by Lender and Borrowers. Lender may perform a Borrower’s obligations, or delay or fail to exercise any of
Lender’s rights or remedies, without causing a waiver of those obligations or rights. A waiver on one occasion shall not constitute a waiver on another occasion. Borrowers’ obligations under this Note shall not be affected if Lender
amends, compromises, exchanges, fails to exercise, impairs or releases: (i) any of the obligations belonging to any co-borrower, indorser or guarantor, (ii) any of its rights against any co-borrower, guarantor or indorser, or
(iii) any of the Loan Collateral. 
  

 -7- 

 Waivers of Borrowers. To the extent not prohibited by law or required by the Credit Agreement, demand,
presentment, protest and notice of dishonor, notice of protest and notice of default are hereby waived by each Borrower, and any indorser or guarantor hereof. Borrowers and all co-makers and accommodation makers of this Note hereby waive all
suretyship defenses, including, but not limited to, all defenses based upon impairment of collateral and all suretyship defenses described in Section 3-605 of the Uniform Commercial Code (the “UCC”). Such waiver is entered to
the fullest extent permitted by Section 3-605 of the UCC. 
 Governing Law; Consent to Jurisdiction. This Note is delivered in, is intended to be
performed in, will be construed and enforceable in accordance with and governed by the internal laws of, the State of Ohio, without regard to principles of conflicts of law. Each Borrower agrees that the state and federal courts in Hamilton County,
Ohio shall, at Lender’s sole option, have exclusive jurisdiction over all matters arising out of this Note, WITHOUT LIMITATION ON THE ABILITY OF LENDER, ITS SUCCESSORS AND ASSIGNS, TO INITIATE AND PROSECUTE IN ANY APPLICABLE JURISDICTION
ACTIONS RELATED TO THE REPAYMENT AND COLLECTION OF THE OBLIGATIONS AND THE EXERCISE OF ALL OF LENDER’S RIGHTS AGAINST EACH BORROWER WITH RESPECT THERETO AND ANY SECURITY OR PROPERTY OF EACH BORROWER, INCLUDING, WITHOUT LIMITATION, DISPOSITIONS
OF THE LOAN COLLATERAL, and that service of process in any such proceeding shall be effective if mailed to Borrowers in accordance with the Credit Agreement. 
 JURY WAIVER. EACH BORROWER, ANY INDORSER OR GUARANTOR HEREOF, AND LENDER WAIVE THE RIGHT TO A TRIAL BY JURY OF ANY MATTERS ARISING OUT OF THIS NOTE OR THE TRANSACTIONS CONTEMPLATED HEREBY.

THIRD BANK, an Ohio banking corporation (together with its successors and assigns, “Lender”), at 38 Fountain Square Plaza, MD #10AT63, Cincinnati, Ohio 45263, or such other address as Lender may provide from time to time, the sum of
FIVE MILLION AND 00/100 Dollars ($5,000,000.00), plus interest as provided herein. The outstanding balance of this Term Promissory Note (this “Note”) shall appear on supplemental bank records and is not necessarily the face amount
of this Note, which record shall evidence the balance due pursuant to this Note at any time. As used herein, “Local Time” means the time at the office of Lender specified in this Note. 
 This Note shall be subject to the terms and conditions of the Credit Agreement dated as of December 29, 2005 among Lender, Borrowers, and certain of Borrowers’
affiliates, as amended by the First Amendment to Credit Agreement dated as of June 8, 2006, the Second Amendment to Credit Agreement dated as of February 28, 2007 and the Third Amendment to Credit Agreement dated as of even date herewith
(as the same may be further amended, renewed, consolidated, restated or replaced from time to time, the “Credit Agreement”). Capitalized terms used herein which are not otherwise defined in this Note shall have the meanings set
forth in the Credit Agreement. This Note is entitled to the benefits and security of the Credit Agreement, including, without limitation, acceleration upon the terms provided therein, and of the other Loan Documents.

	Each calendar month from and including April 1, 2008 through, and including, January 1, 2010	  	$	83,333.33

 The entire unpaid principal balance of this Note, together with all accrued and unpaid interest and any other charges,
advances and fees, if any, outstanding hereunder, shall be due and payable in full on the earlier of the Maturity Date or upon acceleration of the Indebtedness evidenced by this Note, notwithstanding any other inconsistent or contradictory
provisions contained in this Note. No part of the Indebtedness evidenced by this Note may, on the repayment thereof, be redrawn or reborrowed by Borrowers. 
 Upon the occurrence and during the continuance of any Event of Default, the entire unpaid principal balance of this Note, together with all accrued but unpaid interest, and all other Obligations, shall, at Lender’s option, become
immediately due and payable, except that if there occurs an Event of Default of the type described in Sections 6.1(d), 6.1(e), or 6.1(j) of the Credit Agreement, the entire unpaid principal balance of this Note, together with
all accrued but unpaid interest, and all other Obligations shall become automatically and immediately due and payable without notice, which Borrowers hereby waive. 
 Interest. Principal amounts outstanding under this Note shall bear interest commencing on the date hereof at the rate or rates per annum set forth below, which rate or rates shall be designated by Borrowers as more fully set forth
herein (the “Interest Rate”). At any time and from time to time during the term of this Note, so long as no Event of Default has occurred and is continuing and so long as such outstanding principal amounts hereunder are not then
subject to a LIBOR Election, Borrowers may exercise their right to adjust the Interest Rate on amounts of principal outstanding under this Note to one of the rates set forth below upon notice to Lender as set forth below; provided, however,
that once the Interest Rate accruing against any amounts outstanding hereunder is adjusted to a LIBOR Rate for a particular LIBOR Interest Period, Borrowers may not elect to adjust such Interest Rate to a different Interest Rate until the expiration
of such LIBOR Interest Period: 
 (a) LIBOR Rate. Upon telephonic notice to Lender by 10:00 a.m. Local Time given at least two Business Days prior to
the beginning of a LIBOR Interest Period, Borrowers may, subject to the terms of this Note, elect to have a portion or portions of the unpaid principal balance of this Note bear interest at a rate per annum equal to the LIBOR Rate (as defined
herein) plus the Applicable LIBOR Rate Margin (as defined herein) (a “LIBOR Election”). The “LIBOR Rate” is the rate of interest (rounded upwards, if necessary, to the next 1/8 of 1% and adjusted for reserves if
Lender is required to maintain reserves with respect to portions of this Note subject to a LIBOR Election) fixed by the British Bankers’ Association at 11:00 a.m., London, England time, relating to quotations for the one month, two month, or
three month London InterBank Offered Rates, as selected by Borrowers in their LIBOR Election, on U.S. Dollar deposits as published on Bloomberg LP, or, if no longer provided by Bloomberg LP, such rate as shall be determined in good faith by
Lender from such sources as Lender shall determine to be comparable to Bloomberg LP (or any 

  

 - 2 - 

 
successor) as determined by Lender at approximately 10:00 a.m. Local Time on the date of request by Borrowers. Each determination by Lender of the LIBOR Rate
shall be conclusive in the absence of manifest error. Interest accruing based on the LIBOR Rate shall be: (i) calculated based on a 360-day year and charged for the actual number of days elapsed and (ii) payable in arrears on the last day
of the applicable LIBOR Interest Period. The Interest Rate applicable to a particular LIBOR Election shall remain at the rate elected for the remainder of the subject LIBOR Interest Period. 
 The “LIBOR Interest Period” for each portion or portions of the unpaid principal balance of this Note bearing interest with respect to the LIBOR Rate
(each such portion or portions, a “LIBOR Rate Loan”) is a period of one month, two months, or three months, at Borrowers’ election, which period shall commence on a Business Day selected by Borrowers subject to the terms of
this Note. If a LIBOR Interest Period would otherwise end on a day that is not a Business Day, such LIBOR Interest Period shall end on the next succeeding Business Day; provided that, if the next succeeding Business Day falls in a new month,
such LIBOR Interest Period shall end on the immediately preceding Business Day. 
 In addition, notwithstanding anything herein contained to the contrary,
if, prior to or during any period with respect to any LIBOR Election, any change in any law, regulation or official directive, or in the interpretation thereof, by any governmental body charged with the administration thereof, shall make it unlawful
for Lender to fund or maintain its funding in Eurodollars of any portion of the unpaid principal balance of this Note subject to the LIBOR Rate or otherwise to give effect to Lender’s obligations as contemplated hereby: (i) Lender may, by
written notice to Borrowers, declare Lender’s obligations to make, convert into, continue or maintain LIBOR Rate Loans to be terminated forthwith, and (ii) the LIBOR Rate with respect to Lender shall forthwith cease to be in effect, and
interest shall from and after such date be calculated at the Prime Rate as if a Prime Rate Election had been made, and interest shall be paid, in arrears, on the first (1st) day of each calendar month. Borrowers hereby agree to reimburse and
indemnify Lender from all increased costs or fees incurred by Lender subsequent to the date hereof relating to the offering of rates of interest based upon the LIBOR Rate. In addition, notwithstanding anything herein contained to the contrary, if,
prior to or during any period with respect to any LIBOR Election, any change in any law, regulation or official directive, or in the interpretation thereof, by any governmental body charged with the administration thereof, shall: 
  

	 	(i)	increase the cost to Lender, by an amount which Lender deems to be material, of making, converting into, continuing or maintaining LIBOR Rate Loans, or to reduce any amount
receivable hereunder in respect thereof, or 

  

	 	(ii)	have the effect of reducing the rate of return on Lender’s capital as a consequence of its obligations hereunder to a level below that which Lender could have achieved but for
such change by an amount deemed by Lender to be material, 

 then, in any such case, after submission by Lender to Borrowers of a written
request therefor, Borrowers shall pay Lender any additional amounts necessary to compensate Lender for such increased cost or reduction. Lender agrees that, upon the occurrence of any event giving rise to the operation of this paragraph, it will use
reasonable efforts to designate another lending office (if possible) 

  

 - 3 - 

 
for any LIBOR Rate Loans affected by such event with the object of avoiding the consequences of such event; provided, that no such designation shall
be required unless such designation can be made on terms that, in the reasonable judgment of Lender, cause Lender and its lending office(s) to suffer no material economic, legal or regulatory disadvantage. A certificate of Lender setting forth the
amount or amounts necessary to compensate Lender as specified in this paragraph and delivered to Borrowers shall be conclusive absent manifest error. Borrowers shall pay Lender the amount shown as due on any such certificate within 10 days after
receipt thereof. 
 Borrowers’ right to make a LIBOR Election shall be terminated automatically if Lender, by telephonic notice, shall notify Borrowers
that Eurodollar deposits with a maturity corresponding to the maturity of the LIBOR Interest Period, in an amount equal to the unpaid principal balance of this Note to be subject to the LIBOR Election are not readily available in the London
Inter-Bank Offered Rate Market, or that, by reason of circumstances affecting the London Inter-Bank Offered Rate Market, adequate and reasonable methods do not exist for ascertaining the rate of interest applicable to such deposits for the proposed
LIBOR Interest Period. In such event, amounts outstanding hereunder shall bear interest at the Prime Rate as if a Prime Rate Election had been made or at such other rate of interest as may be agreed to between Lender and Borrowers. 
 If any amount as to which a LIBOR Election is in effect is repaid on a day other than the last day of the applicable LIBOR Interest Period, or becomes payable on a day
other than the last day of the applicable LIBOR Interest Period due to acceleration or otherwise, Borrowers, whether or not a debtor in a proceeding under Title 11, United States Code, shall pay, on demand by Lender, such amount (as determined by
Lender) as is required to compensate Lender for any losses, costs or expenses (“LIBOR Breakage Fee”), which Lender may incur as a result of such payment or acceleration, including, without limitation, any loss, cost or expense
(including loss of profit) incurred by reason of liquidation or reemployment of deposits or other funds acquired by Lender to fund or maintain such amount bearing interest at the applicable LIBOR Rate. A certificate of Lender setting forth the
amount or amounts necessary to compensate Lender as specified in this paragraph and delivered to Borrowers shall be conclusive absent manifest error. Borrowers shall pay Lender the amount shown as due on any such certificate within 10 days after
receipt thereof. 
 (b) Prime Rate. Upon telephonic notice by Borrowers to Lender by 10:00 a.m. Local Time, Borrowers may elect to have a portion or
portions of the outstanding principal balance hereunder (provided such amounts are not then subject to a LIBOR Election), bear interest at a floating rate equal to the rate of interest per annum established from time to time by Lender at its
principal office as its “Prime Rate” plus the Applicable Prime Rate Margin (as defined below) (the “Prime Rate Election”) (it being understood by Borrowers that such Prime Rate is established for reference purposes only
and not as Lender’s best loan rate). Any adjustment in the Interest Rate resulting from a change in Lender’s Prime Rate shall become effective as of the opening of business on the date of each change (or if not a Business Day, the
beginning of the day). Interest on the principal amount subject to a Prime Rate Election shall be calculated based on a 360-day year and charged for the actual number of days elapsed, and shall be payable in arrears on the first day of each calendar
month. 
  

 - 4 - 

 On or before the date that is two Business Days before the making of any LIBOR Rate Loan, and on or before the date which
is two Business Days prior to the expiration of any applicable LIBOR Interest Period, Borrowers shall notify Lender of each of the following: (a) the LIBOR Interest Period Borrowers have elected regarding any such LIBOR Rate Loan or any
continuation of a LIBOR Election with respect to any such LIBOR Rate Loan, (b) the amount of each such LIBOR Rate Loan or continuation, and (c) the commencement date of each LIBOR Interest Period. Borrowers may have LIBOR Rate Loans in
minimum amounts of $1,000,000 (and integral multiples of $100,000) and such LIBOR Rate Loans may bear interest at the applicable Interest Rate for different LIBOR Interest Periods so long as (i) the last day of any LIBOR Interest Period does
not exceed the Maturity Date hereof; (ii) no LIBOR Election with respect to any LIBOR Rate Loan commences prior to the expiration of the applicable LIBOR Interest Period in effect with respect to such LIBOR Rate Loan; and (iii) at no time
may Borrowers have more than three outstanding LIBOR Rate Loans, in the aggregate, under all of their Notes and one Prime Rate Election under this Note. If, at any time during the term hereof, Borrowers fail to designate a LIBOR Interest Period or
if Borrowers have not elected another LIBOR Interest Period in accordance with this Note at least two Business Days prior to the expiration of the LIBOR Interest Period then in effect, Lender may assume that Borrowers have elected a Prime Rate
Election. 
 (c) Pricing Grid. As used herein, the terms “Applicable Prime Rate Margin” and “Applicable LIBOR Rate
Margin” (hereafter sometimes collectively referred to as the “Applicable Margins”) mean, as of any date, the applicable per annum rate shown in the applicable column in the table below based on the then applicable Fixed
Charge Coverage Ratio. “Fixed Charge Coverage Ratio” has the meaning given in the Credit Agreement.

	 Pricing Grid
Level
	  	 Fixed Charge Coverage Ratio
	  	Applicable Prime Rate
Margin	 	Applicable LIBOR Rate
Margin
	 Level 1
	  	£1.50 to 1.0	  	0.50%	 	2.75%
	 Level 2
	  	> 1.50 to 1.0 and £ 2.0 to 1.0	  	0.25%	 	2.50%
	 Level 3
	  	> 2.0 to 1.0	  	0.0%	 	2.25%

 For purposes of determining the Applicable Margins: the Fixed Charge Coverage Ratio will, on and after the First
Pricing Grid Determination Date, be determined (i) as of the end of each Fiscal Year ending on and after the First Pricing Grid Determination Date (each such date being a “Determination Date”) and (ii) in the same manner
used to determine the Fixed Charge Coverage Ratio set forth in Section 5.10 of the Credit Agreement. The “First Pricing Grid Determination Date” will be December 31, 2007. On Lender’s receipt of the financial
statements and Compliance Certificate required to be delivered to Lender pursuant to Sections 4.3(b) and 4.3(d) of the Credit Agreement for the Fiscal Year then ended, the Interest Rate will be subject to adjustment in accordance with
the table set forth above in this subparagraph (c) based on the then Fixed Charge Coverage Ratio for such Fiscal Year then ended so long as no Event of Default is existing as of the applicable effective date of adjustment. The foregoing
adjustment, if applicable, will become effective for LIBOR Elections and Prime Rate Elections made with respect to the portion or portions of the unpaid principal balance of this Note, on and after the first day of the first calendar month following
delivery to Lender of the financial statements and Compliance Certificate required to be delivered to Lender pursuant to Sections 4.3(b) and 4.3(d) of the Credit Agreement for the Fiscal Year then ended until the next succeeding
effective date of adjustment pursuant to this subparagraph (c). Each of the financial statements and Compliance Certificate required to be delivered to Lender must be delivered to Lender in compliance with Section 4.3 of the Credit
Agreement. If, however, either the financial statements or the Compliance Certificate required to be delivered to Lender pursuant to Sections 4.3(b) and 4.3(d) of the Credit Agreement have not been delivered in accordance with
Section 4.3 of the Credit Agreement, then, at Lender’s option, commencing on the date upon which such financial statements or Compliance Certificate should have been delivered in accordance with Section 4.3 of the Credit
Agreement and continuing until such financial statements or Compliance Certificate are actually delivered in accordance with Section 4.3 of the Credit Agreement, it shall be assumed for purposes of determining the Applicable Margins,
that the Fixed Charge Coverage Ratio was £ 1.50 to 1.0 and the pricing associated therewith (i.e., Pricing Grid Level 1) will be applicable on the then applicable Determination Date. As of the Effective Date of
this Note, the Applicable Prime Rate Margin is 0.0% per annum and the Applicable LIBOR Rate Margin is 2.25% (i.e., Pricing Grid Level 3, notwithstanding the Loan Parties’ actual Fixed Charge Coverage Ratio prior to and as of such
Effective Date). 
 Maximum Rate. In no event shall the Interest Rate provided for hereunder, together with all fees and charges as provided for
herein or in any other Loan Document which are treated as interest under applicable law (collectively with interest, the “Charges”), exceed the maximum rate legally chargeable by Lender under applicable law for loans of the type
provided for hereunder (the “Maximum Rate”). If, in any month, the Charges, absent such limitation, would have exceeded the Maximum Rate, then the Charges for that month shall be at the Maximum Rate, and, if in future months, such
Charges would otherwise be less than the Maximum Rate, then such Charges shall remain at the Maximum Rate until such time as the amount of Charges paid hereunder and under the other Loan Documents equals the amount of Charges which would have been
paid if the same had not been limited by the Maximum Rate. In the 

  

 - 6 - 

 
event that, upon payment in full of the Obligations, the total amount of Charges paid or accrued in respect of the Indebtedness evidenced by this Note and
the other Obligations is less than the total amount of Charges which would, but for this paragraph, have been paid or accrued if the Charges otherwise set forth in this Note and in the other Loan Documents had at all times been in effect, then
Borrowers shall, to the extent permitted by applicable law, pay to Lender an amount equal to the difference between: (a) the lesser of: (i) the amount of Charges which would have been charged if the Maximum Rate had, at all times, been in
effect or (ii) the amount of Charges which would have accrued had such Charges otherwise provided for in this Note and in the other Loan Documents at all times been in effect and (b) the amount of Charges actually paid or accrued in
respect of the Indebtedness evidenced by this Note or any of the other Loan Documents. In the event that a court of competent jurisdiction determines that Lender has received any Charges in respect of the Indebtedness evidenced by this Note and the
other Loan Documents in excess of the Maximum Rate, such excess shall be deemed received on account of, and shall automatically be applied to reduce, the Obligations owed to Lender other than any Charges, in the inverse order of maturity, and if
there are no Obligations to Lender outstanding, Lender shall refund to Borrowers (or to such Person to which Lender is directed by a court of competent jurisdiction) such excess. 
 Use of Proceeds. Borrowers certify that the proceeds of Term Loan C will be used for the purposes set forth in the Credit Agreement. 
 Default Rate; Fees. To the extent any payment is not made within 15 days after the date when due under this Note and, at or before the end of such 15-day period, there was insufficient Revolving Loan
Availability to charge the full amount of such payment to the loan account with Lender as an advance of the Revolving Loans, Borrowers shall pay to Lender a late payment fee equal to two percent (2%) of that portion of any payment not paid when
due (whether by maturity, acceleration or otherwise). After the occurrence and during the continuation of an Event of Default, Borrowers agree that Lender may, without notice, increase the Interest Rate by an additional 2.0% per annum (the
“Default Rate”); provided that this paragraph shall not be deemed to constitute a waiver of any Event of Default or an agreement by Lender to permit any late payments whatsoever. 
 Prepayment. In addition to the Scheduled Payments set forth in this Note, Borrowers will make each mandatory prepayment of the principal of this Note required by
the Credit Agreement, including, without limitation, the mandatory prepayments of the principal of this Note in the form of Excess Cash Flow Payments in the manner and to the extent set forth in the Credit Agreement. Subject to
Section 6.4(b) of the Credit Agreement, Borrowers may prepay all of this Note at any time; provided that if any prepayment results in any LIBOR Breakage Fee or a Termination Fee (as defined in Section 6.4(b) of the
Credit Agreement), Borrowers will pay such LIBOR Breakage Fee due in accordance with this Note and, as applicable, the Termination Fee. 
 Entire
Agreement. Borrowers agree that there are no conditions or understandings which are not expressed in this Note or the other Loan Documents. 
  

 - 7 - 

 Severability. If any provision of this Note is held to be invalid by a court of competent jurisdiction in a final
order, the invalid provision will, subject to the provisions of this Note with respect to the Maximum Rate, be deemed severed from this Note and shall not affect any part of the remainder of the provisions of this Note. 
 Joint Obligations. All of the obligations of Borrowers hereunder are joint, several and primary. No Borrower shall be or be deemed to be an accommodation party
with respect to this Note. 
 Assignment. Borrowers agree not to assign any of any Borrower’s rights, remedies or obligations described in this
Note without the prior written consent of Lender, which consent may be withheld in Lender’s sole discretion. Borrowers agree that Lender may assign some or all of its rights and remedies described in this Note without prior consent from
Borrowers, provided that Lender will promptly notify Borrowers of a total assignment of this Note. 
 Modification; Waiver of Lender. The
modification or waiver of any of Borrowers’ obligations or Lender’s rights under this Note must be contained in a writing signed by Lender and Borrowers. Lender may perform a Borrower’s obligations, or delay or fail to exercise any of
Lender’s rights or remedies, without causing a waiver of those obligations or rights. A waiver on one occasion shall not constitute a waiver on another occasion. Borrowers’ obligations under this Note shall not be affected if Lender
amends, compromises, exchanges, fails to exercise, impairs or releases: (i) any of the obligations belonging to any co-borrower, indorser or guarantor, (ii) any of its rights against any co-borrower, guarantor or indorser, or
(iii) any of the Loan Collateral. 
 Waivers of Borrowers. To the extent not prohibited by law or required by the Credit Agreement, demand,
presentment, protest and notice of dishonor, notice of protest and notice of default are hereby waived by each Borrower, and any indorser or guarantor hereof. Borrowers and all co-makers and accommodation makers of this Note hereby waive all
suretyship defenses, including, but not limited to, all defenses based upon impairment of collateral and all suretyship defenses described in Section 3-605 of the Uniform Commercial Code (the “UCC”). Such waiver is entered to
the fullest extent permitted by Section 3-605 of the UCC. 
 Governing Law; Consent to Jurisdiction. This Note is delivered in, is intended to be
performed in, will be construed and enforceable in accordance with and governed by the internal laws of, the State of Ohio, without regard to principles of conflicts of law. Each Borrower agrees that the state and federal courts in Hamilton County,
Ohio shall, at Lender’s sole option, have exclusive jurisdiction over all matters arising out of this Note, WITHOUT LIMITATION ON THE ABILITY OF LENDER, ITS SUCCESSORS AND ASSIGNS, TO INITIATE AND PROSECUTE IN ANY APPLICABLE JURISDICTION
ACTIONS RELATED TO THE REPAYMENT AND COLLECTION OF THE OBLIGATIONS AND THE EXERCISE OF ALL OF LENDER’S RIGHTS AGAINST EACH BORROWER WITH RESPECT THERETO AND ANY SECURITY OR PROPERTY OF EACH BORROWER, INCLUDING, WITHOUT LIMITATION, DISPOSITIONS
OF THE LOAN COLLATERAL, and that service of process in any such proceeding shall be effective if mailed to Borrowers in accordance with the Credit Agreement.
