 Commitment Letter – Amendment, Increase and Backstop Commitments 

Ladies and Gentlemen: 
 Reference is made to that certain Credit
Agreement dated as of August 27, 2013 (as amended from time to time and as in effect on the date hereof, the “Credit Agreement”), by and among CECO Environmental Corp., a Delaware corporation
(“you” or the “Company”), Bank of America, N.A. (“Bank of America”), as administrative agent, and the lenders party thereto (the “Existing Lenders”).
Except as expressly provided herein, capitalized terms used in this letter agreement (including the schedules and exhibits hereto, this “Commitment Letter”) and not defined herein shall have the meanings assigned thereto in
the Credit Agreement. 
 You have advised Bank of America and Merrill Lynch, Pierce, Fenner & Smith Incorporated (“MLPFS”)
that you intend to acquire 100% of the equity interests of PMFG, Inc. (the “Target” and such transaction, the “Acquisition”) using a combination of your common stock and up to $66,150,000 of cash
consideration. You have also advised Bank of America and MLPFS that no financing other than the financing described below will be required to finance the Acquisition (including the refinancing of material indebtedness of the Target and its
subsidiaries), the payment of costs and expenses related to the Transaction (as hereinafter defined) or the ongoing working capital and other general corporate needs of the Company and its subsidiaries after the consummation of the Transaction. The
sources and uses for the financing of the Acquisition are as set forth on Schedule I hereto. 
 In connection therewith, you have requested that Bank
of America provide commitments (i) for the full amount of the Additional Term Loan Facility (as hereinafter defined) (the “Increase Commitment”), (ii) as necessary to replace the commitments of Existing Lenders not
consenting to the Amendment (as hereinafter defined) (each such non-consenting Existing Lender, a “Non-Consenting Lender”) and obtain the consent of the Required Lenders for passage of the Amendment (but only to the extent
necessary to obtain such consent and only if the assignment of such commitments by Non-Consenting Lenders can be obtained through the use of commercially reasonable efforts and is permitted under the Credit Agreement) (the “Amendment
Backstop Commitment”), and (iii) if the commercially reasonable efforts of MLPFS fail to achieve the structuring and arrangement of the Amendment and Increase (as hereinafter defined), to provide the full amount of the Replacement
Facilities (as hereinafter defined) (the “Replacement Facilities Commitment”). 
 The senior credit facilities provided under the
Credit Agreement after giving effect to the Amendment and Increase or the Replacement Facilities are from time to time referred to alternatively as the “Senior Credit Facilities.” The Acquisition, the entering into and
funding of the Senior Credit Facilities and all related transactions (including, without limitation, the repayment in full of the material indebtedness of the Target and its subsidiaries and, if the Replacement Facilities are provided, the
indebtedness under the 







 
Credit Agreement) are from time to time referred to collectively as the “Transaction.” The Increase Commitment, Amendment Backstop Commitment and Replacement Facilities
Commitment are from time to time referred to collectively as the “Commitments.” 
 You have also requested that MLPFS, as the sole
lead arranger and sole bookrunner, 
 (a) use its commercially reasonable efforts to structure and arrange an amendment to the Credit
Agreement (the “Amendment”) that (i) amends the “Permitted Acquisition” definition in the Credit Agreement to allow the Acquisition even though the Consolidated Leverage Ratio will not be 0.50 below the
required covenant compliance level after giving effect thereto, (ii) amends Section 7.02(g)(i) to allow the Acquisition even though the aggregate consideration will exceed $150,000,000, (iii) increases the maximum permitted
Consolidated Leverage Ratio (A) through June 29, 2016 to be 3.75 to 1.00, (B) from June 30, 2016 through December 31, 2016 to be 3.50 to 1.00, (C) from January 1, 2017 through September 30, 2017 to be 3.25 to
1.00 and (D) through the remaining term of the Credit Agreement to be 3.00 to 1.00, (iv) amends Section 7.03(f) to the extent necessary to permit the assumption of Chinese debt reflected on Schedule I hereto, (v) amends
the “Consolidated EBITDA” definition in the Credit Agreement to allow the addback of certain cost savings anticipated to be realized as a result of the Acquisition and (vi) amends such other terms as you and we may mutually agree,

 (b) use its commercially reasonable efforts to structure and arrange a new $27,100,000 senior term loan facility (the
“Additional Term Loan Facility” and together with the Amendment, collectively, the “Amendment and Increase”) pursuant to Section 2.15 of the Credit Agreement, which Additional Term Loan
Facility will have the pricing, tenor and amortization set forth on Exhibit A hereto but will otherwise have the same terms as the existing Term Loan Facility, and 

(c) if the efforts contemplated above are unsuccessful, form a syndicate of Lenders (as defined below) to provide senior credit facilities
(the “Replacement Facilities”) to refinance the senior credit facilities under the Credit Agreement, which Replacement Facilities shall have the terms reflected in the Credit Agreement as in effect on the date hereof and as
contemplated to be amended by the Amendment and Increase and all borrowings thereunder on the Closing Date shall be subject only to the conditions precedent specified in Section 2 of this Commitment Letter and Exhibit B hereto (other than
clause (xi) thereof). 
  

	 	1.	COMMITMENTS, ENGAGEMENT AND TITLES. 


(a) Subject to the terms and conditions set forth in this Commitment Letter, 

(i) Bank of America is pleased to advise you of its willingness to provide the Commitments and to act as the sole administrative agent for the

 (ii) MLPFS is pleased to advise you of its willingness, in connection with the Commitments, to act as the
sole lead arranger and sole bookrunner for the Senior Credit Facilities, and, in such capacity, to (A) use its commercially reasonable efforts to (x) arrange and structure the Amendment and Increase, (y) obtain the approvals for the
Amendment from the Existing Lenders required under the Credit Agreement, and (z) obtain commitments from Existing Lenders and other financial institutions and lenders reasonably acceptable to MLPFS and you to provide the Additional Term Loan
Facility and (B) if such efforts are unsuccessful, form a syndicate of financial institutions and other lenders for the Replacement Facilities (such financial institutions and other lenders, the Existing Lenders and the financial institutions
and other lenders providing the Amendment and Increase are from time to time alternatively referred to as the “Lenders”).

	 	3.	SYNDICATION. 

 (a) You agree, until the Syndication
Assistance Termination Date (as hereinafter defined), to actively assist MLPFS in achieving a Successful Syndication (as defined in the Fee Letter). Such assistance shall include (i) your providing and using commercially reasonable efforts to
cause your advisors to provide Bank of America and MLPFS and the other Lenders upon request with all information reasonably deemed necessary by Bank of America and MLPFS to complete the structuring, arrangement and syndication of the Senior Credit
Facilities, including, but not limited to, information and evaluations prepared by you and your advisors, or on your behalf, relating to the Transaction (including the Projections (as hereinafter defined), the “Information”),
(ii) your assistance in the preparation of an Information Memoranda and other materials to be used in connection with the structuring, arrangement and syndication of the Senior Credit Facilities (collectively, the “Information

(iv) otherwise assisting Bank of America and MLPFS in their structuring, arrangement and syndication efforts, including by making your officers and advisors available from time to time upon reasonable advance notice to attend and make
presentations regarding the business and prospects of the Company and its subsidiaries and the Target and its subsidiaries, as appropriate, at one or more meetings of prospective Lenders, in each case, at times and locations to be mutually agreed.

 (b) It is understood and agreed that MLPFS will manage and control all aspects of the structuring, arrangement and syndication of the
Senior Credit Facilities in consultation with you, including decisions as to the selection of prospective Lenders and any titles offered to proposed Lenders, when commitments will be accepted and the final allocations of the commitments among the
Lenders. It is understood that no Lender participating in the Senior Credit Facilities will receive compensation from you in order to obtain its commitment or consent, except on the terms contained in the Fee Letter. It is also understood and agreed
that the amount and distribution of the fees among the Lenders will be at the sole and absolute discretion of Bank of America and MLPFS. 

(c) Notwithstanding the right of MLPFS to structure, arrange and syndicate the Senior Credit Facilities and receive commitments with respect
thereto, (i) Bank of America shall not be relieved, released or novated from its obligations hereunder, including its obligation to fund its Commitments provided hereunder on the date of consummation of the Transaction (the date of such
consummation and funding being referred to as the “Closing Date”), in connection with any syndication, assignment or participation of the Senior Credit Facilities, including its Commitment in respect thereof, until funding of
the Senior Credit Facilities on the Closing Date and (ii) Bank of America shall retain exclusive control over all rights and obligations with respect to its Commitment in respect of the Senior Credit Facilities, including all rights with
respect to consents, modifications, supplements, waivers and amendments, until the Closing Date has occurred, in each case unless you otherwise agree in writing (including, without limitation, pursuant to any revised version of this Commitment
Letter or an amendment or joinder hereto). 

  
 3 








 (d) The provisions of this Section 3 shall remain in full force and effect until the
earliest of (i) ninety (90) days following the Closing Date, (ii) the completion of a Successful Syndication, or (iii) the termination of this Commitment Letter pursuant to the last paragraph hereof other than as a result of the
occurrence of the Closing Date (the “Syndication Assistance Termination Date”). 
  

	 	4.	INFORMATION. 

 (a) You hereby represent, warrant and
covenant that (i) all Information, other than Projections, other forward looking statements and information of a general economic or general industry nature, which has been or is hereafter made available to Bank of America, MLPFS or the Lenders
by you or any of your representatives (or on your or their behalf) in connection with any aspect of the Transaction, as and when furnished, is, when taken as a whole (including any supplements made thereto), and will be, when taken as a whole
(including any supplements made thereto), complete and correct in all material respects, and does not, when taken as a whole (including any supplements made thereto), and will not, when taken as a whole (including any supplements made thereto),
contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein not misleading in any material respect in light of the circumstances in which made, and (ii) all financial
projections concerning the Company and its subsidiaries or the Target and its subsidiaries that have been or are hereafter made available to Bank of America, MLPFS or the Lenders by you or any of your representatives (or on your or their behalf)
(the “Projections”) have been or will be prepared in good faith based upon assumptions believed by you to be reasonable at the time made and at the time the related Projections are made available to Bank of America, MLPFS or
the Lenders (it being understood that any such Projections are subject to uncertainties and contingencies, some of which are beyond your control, that no assurance can be given that any particular Projections will be realized, that actual results
may differ and that such differences may be material). You agree to furnish us with further and supplemental information from time to time until the Closing Date and, if requested by us, from time to time thereafter until the Syndication Assistance
Termination Date so that the representation and warranty in the immediately preceding sentence is correct in all material respects on the Closing Date and, if requested by us, until the Syndication Assistance Termination Date so that the
representation and warranty in the immediately preceding sentence is correct in all material respects on the Closing Date and, if further and supplemental information is requested pursuant to this sentence, on such later date prior to the
Syndication Assistance Termination Date on which the Successful Syndication is completed as if the Information were being furnished, and such representation and warranty were being made, on such date. In issuing this commitment and in structuring,
arranging and syndicating the Senior Credit Facilities, Bank of America and MLPFS are and will be using and relying on the Information without independent verification thereof. 

(b) (i) You acknowledge that (A) MLPFS and/or Bank of America on your behalf will make available Information Materials to the proposed
syndicate of Lenders by posting the Information Materials on IntraLinks, SyndTrak or another similar electronic system and (B) certain prospective Lenders (such Lenders, “Public Lenders”; all other Lenders,
“Private Lenders”) may have personnel that do not wish to receive material non-public information (within the meaning of the United States federal securities laws, “MNPI”) with respect to the
Company, the Target, your or their respective affiliates or any other entity, or the respective securities of any of the foregoing, and who may be engaged in investment and other market-related activities with respect to such entities’
securities. If requested, you will assist us in preparing an additional version of the Information Materials not containing MNPI (the “Public Information Materials”) to be distributed to prospective Public Lenders. 

(ii) Prior to distribution of any Information Materials (A) to prospective Private Lenders, you shall provide us with a
customary letter authorizing the dissemination of the Information Materials and (B) to prospective Public Lenders, you shall provide us with a 

  
 4 








 
customary letter authorizing the dissemination of the Public Information Materials and confirming the absence of MNPI therefrom. In addition, at our request, you shall identify Public Information
Materials by clearly and conspicuously marking the same as “PUBLIC”. 
 (iii) You agree that MLPFS and/or Bank of
America on your behalf may distribute the following documents to all prospective Lenders, unless you advise MLPFS and Bank of America in writing (including by email) within a reasonable time prior to their intended distributions that such material
should only be distributed to prospective Private Lenders: (A) administrative materials for prospective Lenders such as lender meeting invitations and funding and closing memoranda, (B) notifications of changes to the Senior Credit
Facilities’ terms and (C) other materials intended for prospective Lenders after the initial distribution of the Information Materials, including drafts and final versions of the definitive documentation for the Senior Credit Facilities,
whether in the form of the Amendment and Increase or the Replacement Facilities (the “Facilities Documentation”). If you advise us that any of the foregoing items should be distributed only to Private Lenders, then MLPFS and
Bank of America will not distribute such materials to Public Lenders without further discussions with you. You agree (whether or not any Information Materials are marked “PUBLIC”) that Information Materials made available to prospective
Public Lenders in accordance with this Commitment Letter shall not contain MNPI. 
 5. EXPENSES. By executing this
Commitment Letter, you agree to reimburse Bank of America and MLPFS from time to time on demand for all reasonable and documented out-of-pocket fees and expenses (including, but not limited to, (a) the reasonable, actual and documented fees,
disbursements and other charges of McGuireWoods LLP, as counsel to Bank of America and MLPFS, and, if reasonably necessary, of one local counsel and one applicable regulatory counsel in each relevant jurisdiction and (b) reasonable and
documented due diligence expenses) incurred in connection with the Senior Credit Facilities, the structuring, arrangement and syndication thereof, the preparation of the Facilities Documentation and any other aspect of the Transaction. You
acknowledge that we may receive a benefit, including without limitation, a discount, credit or other accommodation, from counsel based on the fees such counsel may receive on account of its relationship with us, including, without limitation, fees
paid pursuant hereto. MLPFS agrees to provide updates to you on a weekly basis with respect to the approximate amount of fees, disbursements and other charges of counsel incurred. 

6. INDEMNIFICATION. You agree to indemnify and hold harmless Bank of America, MLPFS, each Lender and each of their
affiliates and their respective partners, officers, directors, employees, agents, trustees, administrators, managers, advisors and representatives (each, an “Indemnified Party”) from and against (and will reimburse each
Indemnified Party as the same are incurred for) any and all claims, damages, losses, liabilities and expenses (including, without limitation, the reasonable and documented fees, disbursements and other charges of one counsel to the Indemnified
Parties, taken as a whole, and, if reasonably necessary, of one local counsel and one applicable regulatory counsel in each relevant jurisdiction to all such Indemnified Parties, taken as a whole, and, solely in the case of a conflict of interest,
one additional counsel to all affected Indemnified Parties similarly situated, taken as a whole) that may be incurred by or asserted or awarded against any Indemnified Party (collectively, “Losses”), in each case arising out
of or in connection with or by reason of (including, without limitation, in connection with any investigation, litigation or proceeding or preparation of a defense in connection therewith) (a) any matters contemplated by this Commitment Letter,
the Transaction or any related transaction or (b) the Senior Credit Facilities and any other concurrent or subsequent financings or any use made or proposed to be made with the proceeds thereof, except to the extent such Loss is found in a
final, nonappealable judgment by a court of competent jurisdiction to have resulted either from (i) such Indemnified Party’s gross negligence or willful misconduct or (ii) a breach in bad faith by such Indemnified Party of its
obligations under this Commitment Letter. In the case of an 

  
 5 








 
investigation, litigation or proceeding to which the indemnity in this paragraph applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought
by you, your equity holders or creditors or an Indemnified Party, whether or not an Indemnified Party is otherwise a party thereto and whether or not any aspect of the Transaction is consummated. You also agree that no Indemnified Party shall have
any liability (whether direct or indirect, in contract or tort or otherwise) to you or your subsidiaries or affiliates or to your or their respective equity holders or creditors arising out of, related to or in connection with any aspect of the
Transaction, except to the extent of direct, as opposed to special, indirect, consequential or punitive, damages determined in a final, nonappealable judgment by a court of competent jurisdiction to have resulted either from (x) such
Indemnified Party’s gross negligence or willful misconduct or (y) a breach in bad faith by such Indemnified Party of its obligations under this Commitment Letter. Notwithstanding any other provision of this Commitment Letter, no
Indemnified Party shall be liable for any damages arising from the use by others of information or other materials obtained through electronic telecommunications or other information transmission systems, except to the extent of direct, as opposed
to special, indirect, consequential or punitive, damages determined in a final, nonappealable judgment by a court of competent jurisdiction to have resulted either from (i) such Indemnified Party’s gross negligence or willful misconduct or
(ii) a breach in bad faith by such Indemnified Party of its obligations under this Commitment Letter. 
 7.

confidential nature of such information, (v) for purposes of establishing a “due diligence” defense, (vi) to the extent that such information is received by Bank of America or MLPFS from a third party that is not to Bank of
America’s or MLPFS’s knowledge subject to confidentiality obligations to you, (vii) to the extent that such information is independently developed by Bank of America or MLPFS, (viii) to enforce its rights hereunder, or
(ix) to Lenders or potential Lenders, participants or assignees subject to the acknowledgment and acceptance by such Lender or prospective Lender, participant or assignee that such information is being disseminated on a confidential basis (on

processes of Bank of America and/or MLPFS or customary market standards for dissemination of such type of information, and in the event of any electronic access through Intralinks, SyndTrak, another website or similar electronic system or platform,
which shall in any event require “click through” or other affirmative action on the part of the recipient to access such information and acknowledge its confidentiality obligations in respect thereof, in each case on terms reasonably
acceptable to you, Bank of America and MLPFS. Notwithstanding anything to the contrary contained herein, the obligations of Bank of America and MLPFS under this paragraph shall remain in effect until the earlier of (x) the date one year from
the date hereof and (y) the Closing Date, at which point any confidentiality undertakings under the Facilities Documentation shall supersede the provisions of this paragraph.

 EXHIBIT B 

CONDITIONS PRECEDENT TO CLOSING AND INITIAL FUNDING 

The closing and extension of credit under the Senior Credit Facilities, in addition to the conditions precedent set forth in the Commitment Letter, will be
subject to satisfaction of the following conditions precedent: 
  

	(i)	Satisfactory Documentation. Subject to the Certain Funds Provisions (as hereinafter defined), the negotiation, execution and delivery of Facilities Documentation with respect to the Senior Credit Facilities
consistent with the Commitment Letter and reasonably satisfactory to the Company, MLPFS, Bank of America, in its capacity as administrative agent under either the Credit Agreement or the Replacement Facilities, as the case may be (in such capacity,
the “Administrative Agent”), and the Lenders. Without limitation of the foregoing, the Administrative Agent shall receive (A) reasonably satisfactory opinions of counsel to the Company and those of its subsidiaries
serving as either a “Borrower” or a “Guarantor” (which shall cover, among other things, authority, legality, validity, binding effect and enforceability of the documents for the Senior Credit Facilities) and of appropriate local
counsel and such corporate resolutions, certificates and other documents as the Administrative Agent may reasonably require, (B) customary officers’ certificates, good standing certificates and other customary closing documents (including,
without limitation, certificates of insurance (along with related endorsements), lien searches, resolutions and organizational documents), (C) a certificate of the chief financial officer (or equivalent officer) of the Company in substantially
the same form as the form of certificate delivered on the closing date of the Credit Agreement certifying that the Company and the Company and its subsidiaries, taken as a whole, will be solvent after giving effect to the Transaction and the
incurrence of indebtedness related thereto and (D) at least three business days prior to the Closing Date, all documentation and other information required by regulatory authorities under applicable “know your customer” and anti-money
laundering rules and regulations, including without limitation the PATRIOT Act. 

  

	(ii)	Security. Subject to the Certain Funds Provisions, all filings, recordations and searches necessary in connection with the liens and security interests securing the obligations arising in connection with the
Senior Credit Facilities shall have been duly made (it being understood that the scope of the assets of the Company and its subsidiaries subject to such liens and security interests shall be the same as those contemplated by the Credit Agreement and
the Collateral Documents delivered in connection therewith but including the assets of the Target and its subsidiaries, all of such assets, collectively, the “Collateral”); all filing and recording fees and taxes shall have
been duly paid and MLPFS shall have received (x) evidence of the insurance maintained by the Company and its subsidiaries, and the Administrative Agent shall have received certificates naming the Administrative Agent and the Lenders as an
additional insured, in the case of liability insurance, and the Administrative Agent, on behalf of the Lenders, as lenders’ loss payee, in the case of property insurance and (y) reasonably satisfactory evidence that the Administrative
Agent (on behalf of the Lenders) shall have a valid and perfected first priority (subject to certain exceptions to be set forth in the Facilities Documentation) lien and security interest in the Collateral. 


 

	(iii)	 Acquisition. The Acquisition shall have been consummated, or shall be consummated substantially simultaneously with the Closing Date, in all
material respects in accordance with the terms of that certain Agreement and Plan of Merger dated as of May 3, 2015 by and among the Company, the Target, TOP GEAR ACQUISITION INC., a Delaware corporation, and TOP GEAR ACQUISITION II LLC, a
Delaware limited liability company, (including all schedules and exhibits thereto, the “Purchase Agreement”), without giving effect to any modifications, 










	 	
amendments, consents or waivers thereto that are material and adverse to the interests of the Lenders, as reasonably determined by MLPFS, without the prior consent of MLFPS, it being understood
that any substantive material modification, amendment, consent or waiver to (i) the Company Disclosure Schedules (as defined in the Purchase Agreement), the Parent Disclosure Schedules (as defined in the Purchase Agreement) or the definition of
“Material Adverse Effect” in the Purchase Agreement, (ii) the third party beneficiary rights in the Purchase Agreement applicable to MLPFS and/or the Lenders (including, without limitation, any substantive modification, amendment,
consent or waiver of any of the provisions referenced in Sections 9.5(c), 10.5 or 10.8 of the Purchase Agreement) or (iii) the governing law of the Purchase Agreement shall in each case be deemed to be material and adverse
to the interests of the Lenders. As used in this Exhibit B, “Material Adverse Effect” has the meaning set forth in the Purchase Agreement. 


 

	(iv)	Material Adverse Effect. (A) Except as set forth in Section 5.8 of the Parent Disclosure Schedules or in the Parent SEC Reports (as defined in the Purchase Agreement) filed with the SEC since
December 31, 2014 and publicly available prior to the date of the Purchase Agreement, and except for the transactions contemplated by the Purchase Agreement, since December 31, 2014, there has not occurred any event, occurrence, condition,
change, development, set of facts or circumstances that has had or would reasonably be expected to have a Material Adverse Effect on the Company, and (B) except as set forth in Section 4.8 of the Company Disclosure Schedules or in the
Company SEC Reports (as defined in the Purchase Agreement) filed with the SEC since June 28, 2014 and publicly available prior to the date of the Purchase Agreement, and except for the transactions contemplated by the Purchase Agreement, since
June 28, 2014, there has not occurred any event, occurrence, condition, change, development, set of facts or circumstances that has had or would reasonably be expected to have a Material Adverse Effect on the Target. 


 

	(v)	Absence of Litigation. There are no actions, suits, proceedings, claims or disputes pending or, to the actual knowledge of the Company after reasonable inquiry, threatened in writing, at law, in equity, in
arbitration or before any governmental authority, by or against the Company or any of its subsidiaries or the Target or any of its subsidiaries or against any of their properties or revenues that (A) could reasonably be expected to materially
adversely affect the Facilities Documentation or any of the transactions contemplated hereby, or (B) would result in clause (iv) not being satisfied; provided, however, that the foregoing shall not include any shareholder
class action or derivative litigation commenced against the Company or the Target since the date of the Purchase Agreement and arising from allegations of breach of fiduciary duty of the Company’s or the Target’s respective directors
relating to their respective negotiation and approval of the Purchase Agreement or from allegations of false or misleading public disclosure by the Company or the Target with respect to the Transaction, including, without limitation, the Purchase
Agreement. 

  

	(vi)	No Change in Information. All of the Information shall be complete and correct in all material respects considered as a whole; and no new or additional information, shall have been received or discovered by the
Administrative Agent or MLPFS regarding the Company or its subsidiaries, the Target or its subsidiaries or the Transaction after the date of the Commitment Letter that, either individually or in the aggregate, (A) would result in clause
(iv) above or clause (viii) below not being satisfied if such new information were deemed to constitute a change or development for the purposes thereof or (B) could reasonably be expected to materially and adversely affect the Senior
Credit Facilities or any other aspect of the Transaction, and nothing shall have come to the attention of the Lenders to lead them to believe in good faith that any Information Memorandum was or has become misleading, incorrect or incomplete in any
material respect after giving effect to any permitted supplements thereto on or prior to the Closing Date. 









	(vii)	Financial Information. The Administrative Agent shall have received (a) audited financial statements of each of the Company and its subsidiaries as of December 31, 2014 and the Target and its
subsidiaries as of June 28, 2014, (b) all interim financial statements of each of the Company and its subsidiaries and the Target and its subsidiaries from and the after the most recent fiscal year end through the most recent quarter for
which financial statements are available which are not inconsistent with the Information provided to MLPFS prior to the date the Commitment Letter is executed if such inconsistency would result in clause (iv) above or clause (viii) below
not being satisfied, (c) a satisfactory quality of earnings report with respect to the Target and its subsidiaries prepared by an independent certified public accountant acceptable to the Lead Arranger (it being agreed that the quality of
earnings report delivered to the Lead Arranger on April 8, 2015, satisfies this condition) and (d) pro forma consolidated financial statements as to the Company and its subsidiaries giving effect to all elements of the Transaction
to be effected on or before the Closing Date, and forecasts prepared by management of the Company of balance sheets, income statements and cash flow statements on a quarterly basis for the fiscal year 2015 and on an annual basis for each fiscal year
thereafter during the term of the Senior Credit Facilities. 

  

	(viii)	Maximum Total Leverage Ratio. MLPFS shall be satisfied that, on the Closing Date after giving effect to all funding under the Senior Credit Facilities and the Transaction, the Consolidated Leverage Ratio (to be
defined substantially consistently with the definition set forth in the Credit Agreement but to include certain pro forma adjustments to be agreed per the Amendment) shall be less than 3.50 to 1.00. 


 

	(ix)	Accuracy of Representations / No Default. Subject to the Certain Funds Provisions, (A) all of the representations and warranties in the Facilities Documentation shall be true and correct in all material
respects (or, to the extent any such representation and warranty is modified by a materiality or Material Adverse Effect standard, in all respects) as of the Closing Date and (B) no event of default under the Senior Credit Facilities shall have
occurred and be continuing, provided that the condition in this clause (B) shall not be a condition to the availability of the Senior Credit Facilities on the Closing Date with respect to any event of default relating to the making of any
representation or warranty on the Closing Date other than a Specified Representation or a Purchase Agreement Representation (as defined below). 

  

	(x)	Minimum Marketing Period. Information Memoranda in form reasonably satisfactory to MLPFS to be used in connection with the structuring, arrangement and syndication of the Senior Credit Facilities and approved for
disclosure to the Lenders shall have been completed at least 30 business days prior to the Closing Date, and MLPFS shall have been afforded a marketing period of at least 30 business days to seek to structure, arrange and syndicate the Senior Credit
Facilities. 

  

	(xi)	Additional Commitment Amendment. If the Amendment and Increase is provided, the satisfaction of the conditions precedent set forth in Section 2.15 of the Credit Agreement with respect to an Additional
Commitment Amendment (after giving effect to the amendments contemplated in the Commitment Letter). 

  

	(xii)	Payment of Fees and Expenses. Simultaneously with the closing and extension of credit under the Senior Credit Facilities, the payment of all fees and expenses to be payable pursuant to the Commitment Letter and
the Fee Letter (including the reasonable expenses of counsel for Bank of America and MLPFS), limited, in the case of expenses, to those expenses for which a written request has been made. 








 Notwithstanding anything in the Commitment Letter or the Facilities Documentation to the contrary, (i) the
only representations and warranties related to the Target and its subsidiaries in the Facilities Documentation the accuracy of which will be a condition to the availability of the Senior Credit Facilities on the Closing Date will be (A) such
representations and warranties regarding the Target and its subsidiaries in the Purchase Agreement as are material to the interests of Administrative Agent and the Lenders, but only to the extent that the Company or its affiliates have the right to
terminate the Company’s or its affiliates’ obligations under the Purchase Agreement (or the right not to consummate the Acquisition pursuant to the Purchase Agreement) as a result of a failure of such representations and warranties to be
true and correct (the “Purchase Agreement Representations”) and (B) the Specified Representations (as defined below) and (ii) the terms of the Facilities Documentation (including, without limitation, the conditions
precedent to the effectiveness thereof) will not impair availability of the Senior Credit Facilities on the Closing Date if the conditions expressly set forth in Section 2 of the Commitment Letter and this Exhibit B are satisfied
(it being understood that, to the extent a perfected security interest in any collateral (the security interest in respect of which cannot be perfected by means of the filing of a UCC financing statement, the making of a federal intellectual
property filing or delivery of possession of capital stock or other certificated security) is not able to be provided on the Closing Date after the Company’s use of commercially reasonable efforts to do so, the perfection of such security
interest in such collateral will not constitute a condition precedent to the availability of the Senior Credit Facilities on the Closing Date, but a security interest in such collateral will be required to be perfected after the Closing Date
pursuant to arrangements to be mutually agreed between the Company and the Administrative Agent). For purposes hereof, “Specified Representations” mean the representations and warranties relating to legal existence, good
standing, corporate power and authority; the authorization, execution and delivery, and legality, validity and enforceability, of the Facilities Documentation; accuracy of disclosure; the creation and perfection of liens (subject to the limitations
on perfection set forth above); Federal Reserve margin regulations; the Investment Company Act; PATRIOT Act, OFAC and other anti-terrorism laws; anti-corruption laws and sanctions; solvency; governmental approvals; no violation of, or conflict with,
applicable law that could reasonably be expected to have a material adverse effect on the Facilities Documentation; and no violation or conflict with charter documents or material debt agreements as it relates to the Facilities Documentation. For
the avoidance of doubt, the foregoing provisions of this paragraph shall be referred to herein as the “Certain Funds Provisions”.
