	2.	Conditions Precedent 

 Our commitments hereunder to make effective and fund the Facilities on the Closing
Date and our agreements to perform the services described herein are subject solely to the satisfaction of the conditions set forth in Exhibit C. 

Notwithstanding anything in this Commitment Letter (including each of the exhibits attached hereto), the Fee Letter, the Facilities Documentation (as defined
in Exhibit A; Exhibits A, B and C are the “Term Sheets”) or any other letter agreement or other undertaking between you and us concerning the financing of the Transactions to the
contrary, (a) the only representations and warranties the accuracy of which shall be a condition to the availability and effectiveness of the Facilities on the Closing Date shall be (i) such of the representations and warranties made by the Company
with respect to the Company and its subsidiaries in the Acquisition Agreement as are material to the interests of the Lenders (as such term is defined in Exhibit A), but only to the extent that you (or any of your
affiliates) have the right (taking into account any applicable cure provisions) to terminate your (or its) obligations under the Acquisition Agreement or decline to consummate the Acquisition (in each case, in accordance with the terms of the
Acquisition Agreement) as a result of a breach of such representations and warranties in the Acquisition Agreement (the “Specified Acquisition Agreement Representations”) and (ii) the Specified Representations (as defined below) and
(b) the terms of the Facilities Documentation shall be in a form such that they do not impair availability or effectiveness of the Facilities on the Closing Date if all conditions set forth in Exhibit C are satisfied or waived by the
Arrangers (it being understood that to the extent any Collateral or any security interests therein (including the creation or perfection of any security interest) is not or cannot be provided or perfected on the Closing Date (other than (i) to the
extent that a lien on such Collateral may be perfected by the filing of a financing statement under the Uniform Commercial Code or (ii) by the delivery of stock or other certificates of “Merger Sub” (as defined in the Acquisition
Agreement)) after your use of commercially reasonable efforts to do so, or without undue burden or expense, the delivery of such Collateral (and creation or perfection of security interests therein), as applicable, shall not constitute a condition
precedent to the availability or effectiveness of the Facilities on the Closing Date but shall instead be required to be delivered or provided within 90 days after the Closing Date (or such later date as may be reasonably agreed by the Borrower and
the applicable Administrative Agent), and in the case of perfection of security interests in real property, within 120 days after the Closing Date (or such later date as may be reasonably agreed by the Borrower and the applicable Administrative
Agent), in each case, pursuant to arrangements to be mutually agreed by the Borrower and the applicable Administrative Agent). For purposes hereof, “Specified Representations” means the representations and warranties made by the
Loan Parties (as defined in Exhibit A) set forth in the Facilities Documentation relating to: organizational existence of the Loan Parties; organizational power and authority of the Loan Parties, and due authorization, execution and delivery
by the Loan Parties, in each case, as they relate to their entry into and performance of the Facilities Documentation; enforceability of the Facilities Documentation against the Loan Parties; no conflicts with or consent under charter documents of
the Loan Parties as it relates to their entry into and performance of the Facilities Documentation; solvency of the Borrower and its restricted subsidiaries on a consolidated basis on the Closing Date after giving effect to the Transactions (with
solvency being determined in a manner consistent with Annex I to this Commitment Letter); subject to the immediately preceding sentence and the limitations set forth in the Term Sheets, creation and perfection of security interests in the
Collateral; Federal Reserve margin regulations; the PATRIOT Act; not using proceeds in violation of OFAC or FCPA; and the Investment Company Act. The provisions of this paragraph are referred to as the “Certain Funds Provision”.

  

	3.	Syndication 

 Each Arranger intends and reserves the right to syndicate the Facilities to the Lenders;
provided that, unless otherwise agreed by you, no assignment prior to the Closing Date will reduce or release any Commitment Party’s obligation to fund its commitment in the event any assignee shall fail to do so on the Closing Date. The
Arrangers will lead the syndication, including determining, in consultation with you, 

  
 3 

 
the timing of all offers to prospective Lenders, any title of agent or similar designations or roles awarded to any Lender and the acceptance of commitments, the amounts offered and the
compensation provided to each Lender from the amounts to be paid to the Arrangers pursuant to the terms of this Commitment Letter and the Fee Letter and will in consultation with you determine the final commitment allocations. You agree to use
commercially reasonable efforts to ensure that the Arrangers’ syndication efforts benefit from the existing lending and investment banking relationships of the Borrower, the Company and their respective subsidiaries. To facilitate an orderly
and successful syndication of the Facilities, you agree that, until the earliest of (a) the termination by the Arrangers of syndication of the Facilities, (b) 60 days following the Closing Date and (c) the “Successful Syndication” of
the Facilities (as defined in the Fee Letter), you will ensure (or with respect to the Company or its subsidiaries, using your commercially reasonable efforts to ensure) there will be no competing issues, offerings, placements or arrangements of any
debt facility or any debt security of the Company or the Borrower or any of their respective subsidiaries, including any renewal or refinancing of any existing debt facility or debt security, being issued, offered, placed or arranged without the
consent of the Arrangers, if such issuance, offering, placement or arrangement would materially impair the primary syndication of the Facilities (it being understood that (x) as to the Company and its subsidiaries, (i) indebtedness incurred under
its existing domestic revolving credit facility prior to the Refinancing and incurred under its foreign revolving credit facility, and (ii) indebtedness permitted to remain outstanding on and after the Closing Date under the Acquisition Agreement
and (y) as to the Borrower and its subsidiaries, deferred purchase price obligations, ordinary course working capital facilities for foreign subsidiaries, ordinary course capital lease, purchase money and equipment financings and debt securities
issued in accordance with the terms of the Fee Letter will not be deemed to materially impair the primary syndication of the Facilities). 
 You agree to,
and agree to use commercially reasonable efforts to obtain contractual undertakings from the Company to, cooperate with, and provide customary information reasonably required by, the Arrangers in connection with all syndication efforts, including:
(i) your assistance in preparing as soon as practicable after the date of this Commitment Letter, a customary information memorandum and other customary presentation materials (collectively, “Confidential Information
Memoranda”) regarding the business, operations and financial projections of the Borrower and the Company (which shall be, with respect to the Company, limited to the financial information and projections described in Exhibit C)
including without limitation the delivery of all information relating to the Transactions prepared by or on behalf of the Borrower or the Company; (ii) using commercially reasonable efforts to obtain from Moody’s Investor Service, Inc.
(“Moody’s”) and Standard & Poor’s Ratings Services, a Standard & Poor’s Financial Services LLC business (“S&P”), prior to the launch of the general syndication, a corporate
family rating, a corporate credit rating and a credit rating for the Term Loan Facility; (iii) arranging for direct communications with prospective Lenders in connection with the syndication of the Facilities (including without limitation
direct contact between appropriate senior management, representatives and advisors of the Borrower (and using commercially reasonable efforts to cause direct contact with appropriate senior management, representatives and advisors of the Company)
and participation of such persons in such meetings); (iv) hosting (including any preparations with respect thereto) with the Arrangers at places and times reasonably requested by the Arrangers, one or more meetings with prospective Lenders; and (v)
your ensuring the ABL Administrative Agent and its designees shall have sufficient access to the Borrower and its subsidiaries, and your using commercially reasonable efforts to ensure that the ABL Administrative Agent and its designees shall have
sufficient access to the Company and its subsidiaries, to complete a field examination as soon as practicable after the date hereof. You will be solely responsible for the contents of the Confidential Information Memoranda and all other
information, documentation or other materials delivered to us in connection therewith and you acknowledge that we will be using and relying upon such information without independent verification thereof as provided in Section 4 below. Subject
to your consent, not to be unreasonably withheld or delayed, and compliance with applicable laws, you agree that each Arranger has the right to place advertisements in financial and other newspapers at its own expense describing its

  
 4 

 
services to you and the Borrower. We agree that the only financial statements that shall be required to be provided to the Commitment Parties in connection with the syndication of the Facilities
shall be those required to be delivered pursuant to paragraphs 3 and 4 of Exhibit C. Notwithstanding anything to the contrary contained in this Commitment Letter or the Fee Letter or any other letter agreement or undertaking concerning
the financing of the Transactions to the contrary, your obligations to assist in syndication efforts as provided herein (including compliance with any of the provisions set forth in this paragraph), shall not constitute a condition to the
commitments hereunder or the funding of the Facilities on the Closing Date. 
 You understand that certain prospective Lenders (such Lenders,
“Public Lenders”) may have personnel that do not wish to receive MNPI (as defined below). At an Arranger’s request, you agree to assist in the preparation of an additional version of the Confidential Information Memoranda that
does not contain material non-public information (as reasonably determined by you) concerning you, the Company or your or its respective subsidiaries or affiliates or your or its respective securities (collectively, “MNPI”) which is
suitable to make available to Public Lenders. You acknowledge and agree that the following documents may be distributed to Public Lenders (unless you or your counsel promptly notify us (including by email) otherwise and provided that you and your
counsel have been given a reasonable opportunity to review such documents and comply with applicable securities law disclosure obligations): (a) drafts and final versions of the Facilities Documentation; (b) administrative materials prepared by any
Arranger for prospective Lenders (including without limitation a lender meeting invitation, allocations and funding and closing memoranda); and (c) summaries of terms and notification of changes in the terms and conditions of the
Facilities. Before distribution of any Confidential Information Memoranda in connection with the syndication of the Facilities (i) to prospective Lenders that are not Public Lenders, you will provide us with a customary letter authorizing the
dissemination of such materials and (ii) to prospective Public Lenders, you will provide us with a customary letter authorizing the dissemination of information that does not contain MNPI (the “Public Information Materials”) to
Public Lenders and confirming the absence of MNPI therein. The Confidential Information Memoranda provided to Lenders and prospective Lenders will be accompanied by a disclaimer by such recipients exculpating us with respect to any use thereof and
of any related materials by the recipients thereof. In addition, at an Arranger’s request, you will identify Public Information Materials by marking the same as “PUBLIC” and by doing so you shall be deemed to have authorized the
Commitment Parties and the proposed Lenders to treat such Public Information Materials as not containing any MNPI. 
 It is agreed that the completion of
the successful syndication of, or receipt of commitments in respect of, the Facilities will not be a condition to the Commitment Parties’ commitments hereunder. 
  

	4.	Information 

 You represent and warrant covenant that (and with respect to information and projections
relating to the Company and its subsidiaries to the best of your knowledge that) (i) all written information (other than projections, forward looking information and information of a general economic or industry specific nature) that has been
or will be made available to any Arranger, any Commitment Party, the Lenders or any of their respective affiliates by or on behalf of the Company or the Borrower in connection with the Transactions is and will be, when furnished and taken as a
whole, complete and correct in all material respects and does not and will not, when furnished and taken as a whole, contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein
not materially misleading in light of the circumstances under which such statements are made (after giving effect to all supplements thereto) and (ii) the projections and other forward looking information that have been or will be made
available to any Arranger, any Commitment Party, the Lenders or any of their respective affiliates by or on behalf of the Company or the Borrower have been and will be prepared in good faith, and that information with respect to you will be based
upon accounting principles consistent 

  
 5 

 
with your historical audited financial statements most recently provided as of the date hereof and upon assumptions that are believed by the preparer thereof to be reasonable when made and when
made available to such Arranger, such Commitment Party, the Lenders and their respective affiliates; it being understood that such projections and forward-looking statements are as to future events and are not to be viewed as facts, such projections
and forward-looking statements are subject to significant uncertainties and contingencies and that actual results during the period or periods covered by any such information may differ significantly from the projected results, and that no assurance
can be given that the projected results will be realized. You agree that if at any time prior to the later of (x) the Closing Date and (y) the earlier of (i) 60 days following the Closing Date and (ii) the “Successful Syndication” of
the Facilities (as defined in the Fee Letter) you become aware that any of the representations in the preceding sentence would be (to the best of your knowledge with respect to the Company) incorrect in any material respect if made at such time,
then you will (and with respect to information and projections with respect to the Company you will use commercially reasonable efforts to cause the Company to) promptly supplement, or cause to be supplemented, the information and projections so
that (and with respect to information and projections relating to the Company to the best of your knowledge) such representations will be correct in all material respects in light of the circumstances in which statements are made. You
understand that in providing our services pursuant to this Commitment Letter we may use and rely on the information and projections without independent verification thereof. 
  

	5.	Expense and Indemnification 

 To induce us to enter into this Commitment Letter and the Fee Letter and to
proceed with the documentation of the Facilities, you hereby agree to indemnify and hold harmless each Administrative Agent, each Collateral Agent, each Arranger and each other agent or co-agent (if any) designated by any Arranger with respect to
the Facilities, each Lender (including in any event each Commitment Party) and their respective affiliates and each partner, trustee, shareholder, director, officer, employee, advisor, representative, agent, attorney and controlling person thereof
(each of the above, an “Indemnified Person”) from and against any and all actions, suits, proceedings (including any investigations or inquiries), claims, losses, damages, liabilities or expenses (including legal expenses), joint or
several, of any kind or nature whatsoever that may be brought or threatened by the Company, the Borrower, the Guarantors (as defined in Exhibit A), any of their respective affiliates or any other person or entity or which may be incurred by
or asserted against or involve any Indemnified Person (whether or not any Indemnified Person is a party to such action, suit, proceeding or claim) as a result of or arising out of or in any way related to or resulting from the Acquisition, this
Commitment Letter, the Fee Letter, the Facilities, the Transactions or any related transaction contemplated hereby or thereby or any use or intended use of the proceeds of the Facilities; provided that you will not have to indemnify an
Indemnified Person against (A) any claim, loss, damage, liability or expense to the extent found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from (i) the gross negligence or willful misconduct of
such Indemnified Person, (ii) a material breach of obligations under the Commitment Letter or the Facilities Documentation by such Indemnified Person or (iii) any dispute solely among the Indemnified Persons (not arising as a result of any act or
omission by the Borrower or any of its subsidiaries or affiliates) other than any claim, action, suit, inquiry, litigation, investigation or other proceeding brought by or against any such Indemnified Person in its capacity as agent or arranger, or
(B) any settlement entered into by such Indemnified Person without your written consent (such consent not to be unreasonably withheld, conditioned or delayed), but if settled with your written consent or if there is a final, non-appealable judgment
by a court of competent jurisdiction in any such action, suit, proceeding or claim, you agree to indemnify and hold harmless each Indemnified Person from and against any and all losses, claims, losses, damages, liabilities or expenses by reason of
such settlement or judgment in accordance with the other provisions of this Section 5. You shall not, without the prior written consent of an Indemnified Person (which consent shall not be unreasonably conditioned, withheld or delayed), effect
any settlement or consent to the entry of any judgment of any pending or threatened 

  
 6 

 
action, suit, proceeding or claim in respect of which indemnity could have been sought hereunder by such Indemnified Person unless (i) such settlement includes an unconditional release of such
Indemnified Person in form and substance reasonably satisfactory to such Indemnified Person from all liability on claims that are the subject matter of such action, suit, proceeding or claim, (ii) does not include any statement as to or any
admission of fault, culpability, wrongdoing or a failure to act by or on behalf of any Indemnified Person and (iii) contains customary confidentiality and non-disparagement provisions. Notwithstanding any other provision of this Commitment

information transmission systems, unless such use is found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct on the party of such Indemnified Person. 

You also agree to periodically reimburse us for our reasonable and documented or invoiced out-of-pocket costs and expenses in connection with any matter
referred to in this Commitment Letter or the Fee Letter, including expenses associated with our due diligence efforts and field examinations and the reasonable and documented fees, disbursements and other charges of one primary counsel, one local
counsel in each relevant jurisdiction and counsel otherwise retained with the Borrower’s consent, whether or not the Acquisition is consummated, the Closing Date occurs or any Facilities Documentation is executed and delivered or any
extensions of credit are made under any of the Facilities. 
 Your indemnity and reimbursement obligations under this Section 5 will be binding upon and
inure to the benefit of the successors, assigns, heirs and personal representatives of you and the Indemnified Persons and shall be superseded in each case by the applicable provisions to the extent covered in the definitive financing documentation
upon execution thereof and thereafter shall have no further force and effect. 
 Neither you nor we nor any other Indemnified Person will be responsible or
liable to us or you or any other person or entity for any indirect, special, punitive or consequential damages which may be alleged as a result of the Acquisition, this Commitment Letter, the Fee Letter, the Facilities, the Transactions or any
related transaction contemplated hereby or thereby or any use or intended use of the proceeds of the Facilities; provided that the indemnity and reimbursement obligations under this Section 5 shall not be limited by this sentence.

transactions contemplated hereby, and you acknowledge and agree that no Commitment Party has any obligation to disclose such interests to you. You further acknowledge and agree that nothing in this Commitment Letter, the Fee Letter or the nature of
our services or in any prior relationship will be deemed to create an advisory, fiduciary or agency relationship between us, on the one hand, and you, your equity holders or your affiliates, on the other hand, and you waive, to the fullest extent
permitted by law, any claims you may have against any Commitment Party for breach of fiduciary duty or alleged breach of fiduciary duty and agree that no Commitment Party will have any liability (whether direct or indirect) to you in respect of such

Dollars.
		
	Maturity and Amortization:	  	The Term Loans will mature on the seventh anniversary of the Closing Date (the “Term Maturity Date”).
		
		  	The Term Loans shall be repayable in equal quarterly installments in an aggregate annual amount equal to 1.00% of the original principal amount of the Term Loan Facility payable on the last day of each calendar quarter commencing
with the first full calendar quarter after the Closing Date. The balance of the Term Loans will be payable on the Term Maturity Date.
		
	Availability:	  	The Term Loans were made in a single drawing on the Closing Date. Repayments and prepayments of the Term Loans may not be reborrowed.
		
	Use of Proceeds:	  	The proceeds of the Term Loans shall be used to finance the Transaction Costs, and, to the extent any proceeds remain after such application, for general corporate purposes permitted by the Term Documentation.
		
	 B.     Incremental Facilities:
	  	
		
		  	The Term Documentation shall permit the Borrower to add one or more incremental term loan facilities to the Term Loan Facility (each, an “Incremental Facility”) in an aggregate principal amount of (a) an
amount equal to 50% of pro forma Consolidated EBITDA (to be defined) as of the Closing Date, plus (b) voluntary prepayments of Term Loans, plus (c) unlimited additional amounts so long as on a pro forma basis after
giving effect to the incurrence of any such Incremental Facility (assuming that such facility is senior indebtedness secured by the Collateral on a pari passu basis with the Incremental Facilities) and after giving effect to any acquisition
or dispositions or prepayment of indebtedness consummated in connection therewith and all other appropriate pro forma adjustments (including adjustments for cost-savings and synergies subject to parameters to be agreed), the Secured Leverage
Ratio does not exceed the pro forma Secured Leverage Ratio as of the Closing Date (provided, that the Borrower may

  
 Exhibit A - 3 

			
		  	 elect whether such Incremental Facility has been incurred (in whole or part) under clauses (a), (b) and/or (c) above in its sole
discretion); provided that (i) no Term Lender will be required to participate in any such Incremental Facility, (ii) no event of default exists or would exist after giving effect thereto (provided, however, that in the case of any Incremental
Facility to fund (a) any Permitted Acquisition (as defined below) or other permitted acquisition whose consummation is not conditioned on the availability of, or on obtaining, third party financing and (b) any redemption, repurchase, defeasance,
satisfaction and discharge or repayment of indebtedness requiring irrevocable notice in advance of such redemption, repurchase, defeasance, satisfaction and discharge or repayment (each, a “Limited Condition Transaction”), the
foregoing requirement shall be replaced by the requirement that no event of default shall have occurred and be continuing immediately prior to signing of the applicable purchase or acquisition agreement, and immediately after giving effect to such
signing, (iii) the representations and warranties in the Term Documentation shall be true and correct in all material respects (and in all respects if qualified by materiality) immediately prior to, and after giving effect to, the incurrence of such
Incremental Facility (provided that any bring-down of representations and warranties shall be limited in the case of any Permitted Acquisition to customary “specified representations”), (iv) the maturity date and weighted average
life to maturity of any such Incremental Facility shall be no earlier than the maturity date and weighted average life to maturity, respectively, of the Term Loan Facility, (v) no Incremental Facility shall be secured by assets other than Collateral
or guaranteed by persons other than the Guarantors with respect to the corresponding Term Loans and (vi) the interest rates and amortization schedule applicable to any Incremental Facility shall be determined by the Borrower and the lenders
thereunder on terms and pursuant to documentation to be mutually agreed; provided, further, that if the Applicable Margins (or similar measure of interest margin) applicable to any Incremental Facility is more than 0.50% per
annum greater than the Applicable Margins for the Term Loans, then the Applicable Margins for the Term Loans shall be increased to the extent necessary so that the Applicable Margins (or similar measure of interest margin) for the Incremental
Facility are equal to the Applicable Margins for the Term Loans, plus 0.50% per annum; provided, further, that, in determining the interest rate margins applicable to the Incremental Facility and the Term Loans, (x) arrangement,
commitment or structuring fees and other similar fees not paid or payable generally to lenders but are payable to any lead arranger of such Incremental Facility, and any similar fees not paid or payable generally to lenders but are payable to the
Arrangers (or their affiliates) in connection with the Term Loans shall be excluded, (y) OID and

  
 Exhibit A - 4 

			
		  	upfront fees paid to the lenders thereunder shall be included (with OID and upfront fees being equated to interest based on assumed four-year life to maturity or, if shorter, the actual weighted average life to maturity), and (z) if
the applicable Incremental Facility includes an interest rate floor greater than the applicable interest rate floor under the existing Term Loan Facility, such differential between interest rate floors shall be equated to an increase in the
applicable interest rate margin with respect to such Incremental Facility for purposes of determining whether an increase to the interest rate margin under the existing Term Loan Facility shall be required, but only to the extent an increase in the
interest rate floor in the existing Term Loan Facility would cause an increase in the interest rate then in effect thereunder, and in such case the interest rate floor (but not the interest rate margin) applicable to the existing Term Loan Facility
shall be increased to the extent of such differential between interest rate floors; provided, further, that, with respect to any Incremental Facility, to the extent such terms are not consistent with the Term Loan Facility (except to
the extent permitted by clauses (v) and (vii) of this paragraph), they shall be reasonably satisfactory to the Administrative Agent and any Incremental Facility shall, for purposes of prepayments, be treated in any event no more
favorably than the Term Loan Facility and shall share ratably or less than ratably in any mandatory prepayments of the Term Loan Facility.
		
		  	“Secured Leverage Ratio” means the ratio of (a) Consolidated Secured Debt (i.e., consolidated total debt of the Borrower and its restricted subsidiaries that is secured by a lien on any assets of the Borrower or
any of its restricted subsidiaries) as of such date to (b) Consolidated EBITDA (to be defined) for the period of four consecutive fiscal quarters of the Borrower last ended for which financial statements have been delivered or were required to have
been delivered (the “Test Period”).
		
	 C.     Refinancing Term Facilities:
	  	
		
		  	The Term Documentation shall permit the Borrower to refinance the then outstanding Term Loans from time to time, in whole or in part, with (x) one or more new term facilities (each, a “Refinancing Term
Facility”), under the Term Documentation with the consent of the Borrower, the Administrative Agent and the institutions providing such Refinancing Term Facility or (y) with one or more additional series of senior unsecured notes or loans,
or senior secured notes that will be secured by the Collateral on a pari passu or junior basis with the Term Loan Facility, senior subordinated (including unsecured) notes or loans, or subordinated (including unsecured) notes or loans (any
such notes or loans, the “Refinancing Notes”, and, together with

  
 Exhibit A - 5 

			
		  	the Refinancing Term Facility, the “Refinancing Indebtedness”); provided that with respect to any such refinancing in part (i) any such Refinancing Term Facility or Refinancing Notes do not mature prior to
the maturity date of, or have a shorter weighted average life than, the Term Loan Facility or Incremental Facility, in either case, that are being refinanced, (ii) the amount of any such Refinancing Indebtedness does not exceed the amount of
indebtedness being refinanced (plus any premium, accrued interest or fees and expenses in respect of the refinancing thereof), plus additional amounts to the extent the Borrower has available debt capacity under other baskets or
carve-outs, (iii) any such Refinancing Indebtedness is not guaranteed by any persons other than the Guarantors under the Term Loan Facility, (iv) if secured, any such Refinancing Indebtedness shall only be secured by the Collateral securing the
Term Loan Facility on a pari passu or junior basis with the Term Loan Facility pursuant to the Term Documentation and shall not be secured by any assets not securing the obligations under such Term Loan Facility, (v) customary subordination
or intercreditor agreements reasonably acceptable to the Administrative Agent are entered into for any such secured, subordinated or senior subordinated Refinancing Notes and (vi) either (x) the covenants and events of default and the other terms
and conditions of such Refinancing Term Facility or Refinancing Notes (excluding pricing and optional prepayment or redemption terms) are, taken as a whole, not more favorable to the investors providing such Refinancing Term Facility or Refinancing
Notes, as applicable, than, those applicable to the Term Loan Facility (except for covenants or other provisions applicable only to periods after the latest final maturity date of any then outstanding Term Loan Facility existing at the time of such
refinancing) or (y) the Term Lenders are afforded the benefits of substantially similar provisions.
		
	 3.      CERTAIN PAYMENT PROVISIONS
	  	
		
	Interest Rate Options:	  	The Borrower may elect that the Term Loan Facility comprising each borrowing bear interest at a rate per annum equal to (a) the ABR plus the Applicable Margin or (b) the Eurodollar Rate, plus the Applicable
Margin.
		
		  	As used herein:
		
		  	“ABR” means the highest of (i) the rate of interest last quoted by The Wall Street Journal as the “Prime Rate” in the U.S. or, if The Wall Street Journal ceases to quote such rate, the highest per
annum interest rate published by the Federal Reserve Board in Federal Reserve Statistical Release H.15 (519) (Selected Interest Rate) as the “bank prime loan” rate or, if such rate is no longer quoted therein, any similar rate quote
therein (as determined by the Administrative Agent) or similar release by the Federal Reserve Board (as determined by

  
 Exhibit A - 6 

			
	 	  	the Administrative Agent) (the “Prime Rate”), (ii) the federal funds effective rate from
time to time (which rate, if negative, shall be deemed to be 0.00%) plus 0.50% and (iii)
the Eurodollar Rate
applicable for an interest period of one month plus 1.00%;
provided, however, that notwithstanding the rate calculated in accordance with the
foregoing, at no time shall the ABR for the Term Loan Facility be deemed to be
less
than 1.75% per annum.
		
		  	“ABR Loans” means Loans bearing interest based upon the ABR.
		
		  	“Applicable Margin” means (i) 3.50%, in the case of ABR Loans and (ii) 4.50%, in the case of Eurodollar Loans.
		
		  	“Eurodollar Loans” means Loans bearing interest based upon the Eurodollar Rate (as defined below).
		
		  	“Eurodollar Rate” means the rate (adjusted for statutory reserve requirements for eurocurrency liabilities) for eurodollar deposits for a period equal to one, two, three or six months or any longer period agreed
to by all relevant lenders (as selected by the Borrower) appearing on the page of the Reuters Screen which displays an average ICE Benchmark Administration Interest Settlement Rate or any successor substitute page (such page currently being LIBOR01
page) (which rate, if negative, shall be deemed to be 0.00%); provided, however, that notwithstanding the rate calculated in accordance with the foregoing, at no time shall the Eurodollar Rate for the Term Loan Facility be deemed to be
less than 0.75% per annum.
		
	Interest Payment Dates:	  	In the case of ABR Loans, quarterly in arrears.
		
		  	In the case of Eurodollar Loans, on the last day of each relevant interest period and, in the case of any interest period longer than three months, on each successive date three months after the first day of such interest
period.
		
	Default Rate:	  	At any time when any Loan Party is in default in the payment of any amount under the Term Loan Facility, after giving effect to any applicable grace period, such overdue amounts shall bear interest at 2.00% per annum above
the rate otherwise applicable thereto, and with respect to any overdue amount (including overdue interest) for which there is no applicable rate, 2.00% per annum in excess of the rate otherwise applicable to Term Loans maintained as ABR Loans
from time to time.

  
 Exhibit A - 7 

					
	Rate and Fee Basis:	 	All per annum rates shall be calculated on the basis of a year of 360 days (or 365/366 days, in the case of ABR Loans) for actual days elapsed.
		
	Optional Prepayments and Commitment Reductions:	 	  
 The Term Loans may be prepaid, in whole or in part
without premium or penalty (other than as set forth under “Soft-Call Premium” below), in minimum amounts set forth in the Term Documentation, at the option of the Borrower at any time upon one business day’s (or, in the case of a
prepayment of Eurodollar Loans, three business days’) prior notice, subject to reimbursement of the Term Lenders’ redeployment costs in the case of a prepayment of Eurodollar Loans prior to the last day of the relevant interest period.
Optional prepayments of the Term Loans, together with accrued interest, if any, shall be applied as directed by the Borrower (and absent such direction, in direct order of maturity thereof).

		
	Soft-Call Premium:	 	In the event that all or any portion of the Term Loan Facility is repriced downward, effectively refinanced through any amendment of the Term Loan Facility or refinanced with the proceeds of other syndicated bank debt
financing, in each case resulting in a lower yield on such amended Term Loan Facility or refinancing indebtedness, as applicable, than that existing on the Term Loan Facility prior to such amendment or refinancing, for any reason on or prior to the
date that is six months after the Closing Date, such repricings, effective refinancings or refinancings will be made with the payment of a 1.00% premium on the amount repriced, effectively refinanced or refinanced (including with respect to the
loans and commitments of any lenders replaced in connection with any amendment related thereto); provided that the foregoing payment shall not apply in the case of any prepayment or refinancing in connection with a change of control or an
acquisition that is not a Permitted Acquisition. All voluntary prepayments under the Term Loan Facility shall be applied to the remaining amortization payments thereunder as directed by the Borrower and as between the Term Loan Facility and any
Incremental Facility, as directed by the Borrower.
		
	Mandatory Prepayments:	 	Mandatory repayments of the Term Loans shall be required from:
			
		 	(a)	 	with respect to any non-ordinary course asset sale or other disposition of assets with net proceeds of $5 million or more in any transaction or series of related transactions, 100% of the net cash proceeds (which shall be defined
to exclude, among other things, the amount of any required tax payments that the Loan Parties shall be

  
 Exhibit A - 8 

					
		 		 	required to make as a result of such sale or disposition) from any non-ordinary course sale or other disposition of assets (including as a result of casualty or condemnation) by the Loan Parties and their restricted subsidiaries,
excluding up to $200 million in the aggregate for all such sales and other dispositions that are consummated within 18 months after the Closing Date and subject to the right of the Loan Parties to reinvest such proceeds if such proceeds are
reinvested (or committed to be reinvested) within 12 months and, if so committed to reinvestment, reinvested within 18 months thereafter, and other exceptions as set forth in the Term Documentation, it being understood and agreed that any such
repayments pursuant to this clause (a) shall only be required when the aggregate amount of excess net cash proceeds from such non-ordinary course asset sales or other disposition of assets, after giving effect to any applicable reinvestment rights,
exceeds $5 million (the “Excess Proceeds Threshold”);
			
		 	(b)	 	100% of the net cash proceeds from issuances or incurrences of debt by the Borrower and its restricted subsidiaries (other than indebtedness permitted by the Term Documentation (other than Refinancing Indebtedness));
and
			
		 	(c)	 	50% (with step-downs to 25% and 0%, each based upon achievement of Total Leverage Ratios (i.e., the ratio of (a) Consolidated Total Indebtedness (i.e., all indebtedness of the Borrower and its restricted subsidiaries) to
(b) Consolidated EBITDA for such Test Period (to be defined), of annual Excess Cash Flow (to be defined) (commencing with Excess Cash Flow for the fiscal year ending December 31, 2016, provided that solely for the fiscal year ending
December 31, 2016, Excess Cash Flow shall equal the annual Excess Cash Flow for such year multiplied by the number of days from the Closing Date to December 31, 2016 divided by 360); provided that any voluntary prepayments of Term
Loans and ABL Loans to the extent commitments under the ABL Facility are permanently reduced by the amount of such prepayments, other than payments or reductions funded with the proceeds of equity or long-term indebtedness, during such fiscal year
shall be credited against Excess Cash Flow prepayment obligations on a dollar-for-dollar basis for such fiscal year.
		
		 	Mandatory prepayments shall be applied, without premium or penalty (other than any Soft-Call Premium payable in connection

  
 Exhibit A - 9 

			
		  	with any Refinancing Indebtedness in the case of clause (b) above), subject to reimbursement of the Term Lenders’ redeployment costs in the case of a prepayment of Eurodollar borrowings other than on the last day of
the relevant interest period, first to the next eight succeeding scheduled installments thereof in direct order of maturity and second ratably to the remaining respective installments thereof.
		
		  	Prepayments from foreign subsidiaries’ Excess Cash Flow and asset sale proceeds (to the extent otherwise required) shall be limited under the definitive documentation to the extent (x) the repatriation of funds to fund such
prepayments is prohibited, restricted or delayed by applicable laws or (y) repatriation of funds to fund such prepayment would result in material adverse tax consequences, as reasonably determined by the Borrower.
		
		  	All mandatory prepayments under clauses (a) and (c) above are subject to permissibility under (a) local law (e.g., financial assistance, corporate benefit, restrictions on upstreaming of cash intra-group and the fiduciary and
statutory duties of the directors of the relevant subsidiaries) and (b) organizational document restrictions (including as a result of minority ownership). The non-application of any such mandatory prepayment amounts as a result of the foregoing
provisions will not constitute a default or an event of default and such amounts shall be available for working capital purposes of the Borrower and its restricted subsidiaries. The Borrower will use commercially reasonable efforts for to overcome
or eliminate any such restriction and/or minimize any such costs of prepayment.
		
		  	Any Term Lender may elect not to accept its pro rata portion of any mandatory prepayment (each a “Declining Lender”). Any prepayment amount declined by a Declining Lender (“Rejected
Amounts”) may be retained by the Borrower and used by the Borrower in any manner not prohibited by the Term Documentation and any such retained amounts will not thereafter be counted as excess cash flow or net cash proceeds (as described
above) in any subsequent measurement period.
		
	 4.      COLLATERAL
	  	
		
	Collateral:	  	Subject to exclusions and limitations as set forth in the Term Documentation and subject to the Certain Funds Provision, the obligations of the Borrower and each Guarantor in respect of the Term Loan Facility and any swap
agreements and cash management arrangements provided by any Term Lender or Arranger (or any affiliate of a Term Lender or Arranger) shall be secured by (a) a perfected first-priority security interest (subject to permitted liens) in all or
substantially all of the Loan Parties’

  
 Exhibit A - 10 

			
		 	tangible and intangible personal property assets other than ABL Priority Collateral, including, without limitation, registered intellectual property, intercompany notes and all of the capital stock of the Borrower and each of its
direct and indirect restricted subsidiaries (limited to (i) the assets of each Guarantor and (ii) 65% of the voting capital stock, and 100% of the non-voting capital stock, of any first-tier Excluded Tax Subsidiary) (the “Term Priority
Collateral”) and (b) a perfected second-priority security interest in all or substantially all of the Loan Parties’ existing and future cash, cash equivalents, bank accounts (with exceptions to be agreed), accounts receivable, other
receivables, chattel paper, inventory, and contract rights, documents, general intangibles (excluding, for the avoidance of doubt, except as needed to liquidate the collateral, trademarks, trade names and other intellectual property) and insurance,
instruments and books and records relating thereto and all proceeds of the foregoing (the “ABL Priority Collateral” and, together with the Term Priority Collateral, the “Collateral”).
		
		 	Notwithstanding anything to the contrary, the Collateral shall exclude (or not require actions with respect thereto as described below) the following: (i) (a) leasehold interests and (b) real property
(1) located outside of the United States or (2) with a value (as determined in good faith by the Borrower) of less than an amount to be agreed, (ii) any assets located outside of the United States or with a value (as determined in
good faith by the Borrower) of less than an amount to be agreed, (iii) vehicles and other assets subject to certificates of title, (iv) letter of credit rights and commercial tort claims with a value, in each case, less than an amount as
set forth in the Term Documentation, (v) any lease, license or other agreement or any property subject to a purchase money security interest or similar arrangement or where the granting of a security interest in any assets would be prohibited
by contract, applicable law or regulation or the organizational documents of any non-wholly owned restricted subsidiary (in each case only to the extent that such contractual provisions are not rendered ineffective by applicable law or otherwise
unenforceable), in each case, to the extent that a grant of a security interest therein would violate or invalidate such lease, license or agreement, purchase money financing, capital lease or a similar arrangement or create a right of termination
in favor of any other party thereto (other than the Borrower or a Guarantor) after giving effect to the applicable anti-assignment provisions of the Uniform Commercial Code, other than proceeds and receivables thereof, the assignment of which is
expressly deemed effective under the Uniform Commercial Code notwithstanding such prohibition, (vi) governmental licenses or state and local franchises, charters, and authorizations and any other property and assets to the extent the
Administrative Agent

  
 Exhibit A - 11 

			
		  	may not validly possess a security interest therein under applicable laws (including without limitation, rules and regulations of any governmental authority or agency) or the pledge or creation of a security interest therein
would require governmental consent, approval, license or authorization, other than to the extent such prohibition or limitation is rendered ineffective under the Uniform Commercial Code or other applicable law notwithstanding such prohibition, (vii)
any intent to use trademark application prior to the filing of a “Statement of Use” or “Amendment to Allege Use” with respect thereto, to the extent, if any, that, and solely during the period, if any, in which the grant of a
security interest therein would impair the validity or enforceability of such intent to use trademark application under applicable federal law, (viii) zero balance accounts, payroll accounts, withholding and trust accounts, tax accounts, escrow or
other fiduciary accounts; (ix) those assets as to which the Administrative Agent and the Borrower agree in writing shall be excluded where the costs and burdens of obtaining a security interest therein or perfection thereof outweigh the benefit to
the Term Lenders of the security to be afforded thereby; and (x) other exceptions as set forth in the Term Documentation. The foregoing described in clauses (i) through (x) are, collectively, the “Excluded
Assets”.
		
		  	None of the Collateral shall be subject to any other pledges, security interests or mortgages, except junior liens on pledged equity interests and instruments and other liens in each case as permitted under the lien covenant.
Notwithstanding the foregoing, no foreign law governed documents, perfection actions or foreign law opinions shall be required in connection with the Facilities.
		
	Intercreditor Agreement:	  	The relative rights and priorities in the Collateral among the ABL Lenders, on the one hand, and the Term Lenders, on the other hand, will be set forth in a customary intercreditor agreement that is reasonably acceptable to the

payment multiplied by (ii) the arithmetic mean

  
 Exhibit A - 15 

			
		  	of the closing prices per share of such common (or common equivalent) equity interests for the 30 consecutive trading days immediately preceding the date of declaration of such restricted payment) for all dates of declaration of
such restricted payments during such fiscal year;

interests in a person that, upon the consummation thereof, will be a restricted subsidiary of Borrower or will be owned by Borrower or any restricted subsidiary of Borrower (including, in each case, as a result of merger or consolidation) (each, a
“Permitted Acquisition”), so long as (a) there is no event of default after giving pro forma effect to such acquisition and the incurrence of indebtedness in connection therewith (at the time of such acquisition or, in
the case of a Limited Condition Transaction, at the time of signing), (b) to the extent required under “Guarantees” and “Collateral” above, the acquired company and its subsidiaries will become Guarantors and pledge their
Collateral to the Administrative

  
 Exhibit A - 16 

			
		  	Agent; provided that, if any security interest in any Collateral (including the creation or perfection of any security interest) is not or cannot reasonably be created and/or perfected on the closing date of such Permitted
Acquisition after the Borrower’s use of commercially reasonable efforts to do so, or without undue burden expense, then the creation and/or perfection of any such Collateral shall not constitute a requirement to close such Permitted
Acquisition, but instead shall be created and/or perfected within 90 days after the closing date of such Permitted Acquisition or such later date as the Administrative Agent may reasonably agree, pursuant to reasonably satisfactory arrangements as
set forth in the Term Documentation and (c) the aggregate amount of consideration paid directly or indirectly by the Loan Parties for acquisitions of or investments in entities that are not required to become Loan Parties after the consummation of
such acquisition or investment shall be subject to a cap as set forth in the Term Documentation.
		
	Events of Default:	  	Limited to the following and applicable to the Borrower and its restricted subsidiaries only, and with materiality, grace periods and other qualifications as set forth in the Term Documentation: nonpayment of principal when due;
nonpayment of interest, fees or other amounts after a three business day grace period; material inaccuracy of a representation or warranty when made or deemed made; violation of covenants (subject, in the case of certain of such affirmative
covenants, to a thirty day grace period); cross-default and cross acceleration to material indebtedness (provided that the Borrower’s failure to perform or observe the Financial Covenant(s) (as
defined in Exhibit B) with respect to the ABL Facility shall not constitute an Event of Default for purposes of the Term Loan Facility unless and until the ABL Lenders have actually declared all such obligations under the ABL Facility to be
immediately due and payable and such declaration has not been rescinded); bankruptcy events of the Borrower or any restricted subsidiary that is not an immaterial subsidiary (with a customary grace period for involuntary events); certain ERISA
events; material unsatisfied judgments; actual or asserted invalidity of any material provision in a guarantee, security document or material subordination provisions or non-perfection of a security interest covering a material portion of the
collateral; and a change of control.
		
	 Voting, Assignments and
 Participations, Yield
Protection:
	  	  
 After the Closing Date, the Term Lenders shall be permitted to
assign (except to disqualified lenders, if the list of disqualified lenders has been provided to all Term Lenders) the Term Loans with the consent of the Borrower (not to be unreasonably withheld or delayed) (the Borrower’s consent shall be
deemed given if it fails to respond within ten business days); provided

  
 Exhibit A - 17 

			
		  	that no consent of the Borrower shall be required (i) after the occurrence and during the continuance of a payment or bankruptcy event of default or (ii) for assignments of loans to any existing Term Lender or an affiliate or
related fund of an existing Term Lender. All assignments will require the consent of the Administrative Agent (not to be unreasonably withheld or delayed) unless such assignment is an assignment of the Term Loans to another Term Lender, an affiliate
of a Term Lender or an approved fund. Each assignment will be in an amount of an integral multiple as set forth in the Term Documentation or, in each case, if less, all of such Term Lender’s remaining loans and commitments of the applicable
class. Natural persons and the Borrower, its subsidiaries and affiliates may not be assignees.
		
		  	 Notwithstanding the foregoing, the Administrative Agent shall not be responsible for monitoring assignments or participations for
compliance with the list of disqualified institutions, if any.
  
 The Term Lenders are
permitted to sell participations in Term Loans and commitments without restriction (except to disqualified lenders, if the list of disqualified lenders has been provided to all Term Lenders), other than as set forth in the next sentence, and in
accordance with applicable law. Voting rights of participants shall be limited to matters in respect of (a) increases in commitments participated to such participants, (b) reductions of principal, interest or fees, (c) extensions of
final maturity and (d) releases of all or substantially all of the value of the Guarantees or all or substantially all of the Collateral.
  

The Borrower may repurchase Term Loans on a non-pro rata basis through a Dutch auction process (or other procedures as set forth in the Term
Documentation by the Borrower and the Administrative Agent) offered to all Term Lenders on customary terms; provided that (i) any Term Loans so repurchased shall be immediately cancelled upon repurchase, and (ii) no event of default
shall have occurred and be continuing.
  
 Notwithstanding the foregoing, the
Administrative Agent is not obligated to act as agent for any Loan repurchases by the Borrower, and the Borrower may engage a separate firm to act in such capacity.
  

Amendments and waivers with respect to the Term Documentation shall require the approval of Term Lenders holding more than 50% of the aggregate amount
Loans and commitments under the Term Loan Facility (the “Required Lenders”), except that (a) in addition to the consent of the Required Lenders, the consent of each Term Lender directly affected thereby shall be required with
respect to (i) reductions in

  
 Exhibit A - 18 

			
		  	the amount or extensions of the scheduled date of any amortization or final maturity of any Loan and (ii) reductions in the rate of interest or any fee or extensions of any due date thereof (but, for the avoidance of doubt,
other than default rate interest) and (iv) increases in the amount or extensions of the expiry date of any Term Lender’s commitment, (b) the consent of 100% of the Term Lenders shall be required with respect to (i) reductions of any
of the voting percentages and modifications of any pro rata sharing and payment provisions, (ii) releases of all or substantially all the Collateral (other than in connection with any sale of Collateral permitted by the Term
Documentation) and (iii) releases of all or substantially all of the Guarantors (other than in connection with the release or sale of the relevant Guarantor permitted by the Term Documentation) and (c) the consent of Administrative Agent shall
be required with respect to any amendment or modification that affects its rights or duties as administrative agent. Any amendment or waiver that by its terms affects only the rights or duties of Term Lenders holding loans or commitments of a
particular class (but not the Term Lenders holding loans or commitments of any other class) will require only the requisite percentage in interest of the affected class of Term Lenders that would be required to consent thereto if such class of Term
Lenders were the only class of Term Lenders.
		
		  	 The Term Documentation contains customary provisions for replacing non-consenting Term Lenders in connection with amendments and waivers
requiring the consent of all Term Lenders or of all Term Lenders directly affected thereby so long as the Required Lenders shall have consented thereto.
  

The Term Documentation shall contain customary protective provisions for such matters as EU bail-in, capital adequacy, increased costs, reserves, funding
losses, illegality, and withholding taxes, including treatment of Dodd-Frank Wall Street Reform and Consumer Protection Act and Basel III as changes in law.

		
	Expenses and Indemnification:	  	The Borrower shall pay (a) all reasonable and documented or invoiced out-of-pocket expenses of the Administrative Agent and the Arrangers in connection with the syndication of the Term Loan Facility and the preparation,
execution, delivery and administration of the Term Documentation and any amendment or waiver with respect thereto (including, without limitation, the reasonable fees, disbursements and other charges of one primary counsel, one local counsel in each
relevant jurisdiction and counsel otherwise retained with the Borrowers’ consent) and (b) all reasonable and documented or invoiced out-of-pocket expenses of the Administrative Agent, the Arrangers and the Term Lenders (including, without
limitation, the fees, disbursements and other charges of counsel) in connection with the enforcement of the Term Documentation.

  
 Exhibit A - 19 

			
		  	The Loan Parties will indemnify the Administrative Agent, the Arrangers and the Term Lenders and their respective affiliates, and the officers, directors, employees, affiliates, agents and controlling persons of the foregoing,
and hold them harmless from and against all costs, expenses (including, without limitation, reasonable fees, disbursements and other charges of counsel) and liabilities of any such indemnified person arising out of or relating to any claim or any
litigation or other proceedings (regardless of whether any such indemnified person is a party thereto or whether such claim, litigation, or other proceeding is brought by a third party or by the Borrowers or any of their respective affiliates,
creditors or shareholders) that relate to the Term Documentation), except to the extent that it is found by a final, non-appealable judgment of a court of competent jurisdiction that such loss, claim, damage, liability or expense resulted from (i)
the gross negligence or willful misconduct of the indemnified party, (ii) a material breach of obligations under the Term Documentation by such indemnified party or (iii) any dispute solely among the indemnified parties (not arising as a result of
any act or omission by the Borrower or any of its subsidiaries or affiliates) other than any claim, action, suit, inquiry, litigation, investigation or other proceeding brought by or against any such indemnified party in its capacity as agent or
arranger.

	Closing Date:	  	“Closing Date” means the date of the effectiveness of the ABL Facility.
	
	 2.      TYPES AND AMOUNTS OF FACILITIES

		
	 A.     ABL Facility
	  	
		
	Type and Amount:	  	A senior secured asset-based revolving facility consisting of commitments and loans in an aggregate principal amount of $50.0 million (the “ABL Facility”; the loans made under the ABL Facility, the “ABL
Loans”; the ABL Loans together with the Term Loans, the “Loans”). The ABL Facility shall be funded in U.S. Dollars, Euros and other currencies to be agreed.
		
	Availability and Maturity:	  	The ABL Facility shall be available subject to the Line Cap on a revolving basis during the period commencing on the Closing Date and ending on the fifth anniversary of the Closing Date (the “ABL Termination
Date”); provided that the amount of the ABL Loans to be drawn on the Closing Date shall only be used to pay amounts described in clauses (ii), (iii) and (iv) of the definition of “Transaction Costs” (as set forth above) and
the original issue discount or upfront fees that result from the exercise of the “Market Flex” provisions in the Fee Letter. The revolving commitments and the ABL Loans under the ABL Facility will mature on the ABL Termination
Date.
		
		  	Overall borrowing availability under the ABL Facility will be equal to the lesser of (a) the aggregate amount of commitments then in effect and (b) the Borrowing Base then in effect (such lesser amount at any time, the
“Line Cap”).

  
 Exhibit B - 2 

			
		  	“Borrowing Base” means (1) the sum of 85% of Eligible Accounts (to be defined) of the Loan Parties; plus (2) subject to MKS’s written notice to the Administrative Agent at least 45 days in advance and
the Administrative Agent’s and its third-party consultants’ and representatives’ completion of customary field examinations and inventory appraisals, the lesser of (a) the lesser of (i) 65% of the lower of cost or market value (on a
first-in-first-out basis) of Eligible Inventory (to be defined) of the Loan Parties and (ii) 85% of the net orderly liquidation value of Eligible Inventory of the Loan Parties and (b) 30% of the Borrowing Base; minus (3) reasonable and
customary reserves established by the Administrative Agent in the exercise of its Permitted Discretion.
		
		  	The Loan Parties shall use commercially reasonable efforts to assist the Administrative Agent and its third-party consultants and representatives to perform customary field examinations and, if MKS elects to include Eligible
Inventory in the Borrowing Base, inventory appraisals, of the Loan Parties prior to the Closing Date. In the event the Administrative Agent has not completed such field examinations and inventory appraisals (if applicable) prior to the Closing Date,
the Loan Parties shall provide the Administrative Agent and its advisors and consultants with sufficient information and access to the Loan Parties and their respective assets to facilitate the completion of such field examinations and inventory
appraisals (if applicable) no later than the 60th day after the Closing Date (subject to extensions by the Administrative Agent in its reasonable discretion). During the period from the Closing Date until the Administrative Agent’s receipt and
reasonable satisfaction with such field examinations and inventory appraisals (if applicable), availability under the ABL Facility shall be equal to 70% of book value of the Loan Parties’ Eligible Accounts and, only to the extent the Borrower
notifies the Administrative Agent in writing of its election to include Eligible Inventory in the Borrowing Base, 35% of the lower of cost or market value (on a first-in-first-out basis) of the Loan Parties’ Eligible Inventory; provided
that (i) if the Administrative Agent’s receipt and reasonable satisfaction with such field examinations and inventory appraisals (if applicable) have not occurred by the 60th day after the Closing Date, the Borrowing Base shall be reduced
to zero until such time that the Administrative Agent’s receipt and reasonable satisfaction with such field examinations and inventory appraisals (if applicable) have occurred and (ii) the Loan Parties shall continue to comply with the
requirement to deliver Borrowing Base certificates during such interim period and upon completion of the field examinations and inventory appraisals (if applicable).

  
 Exhibit B - 3 

			
		  	The initial reserves and initial eligibility criteria will be customary for similar asset-based revolving facilities and shall initially be based on any field examinations (and if any Eligible Inventory has been included in the
Borrowing Base, inventory appraisals) reasonably acceptable to the Arrangers. The Administrative Agent will have the right to modify eligibility standards and establish and modify reserves against Borrowing Base availability, in each case acting
within the Administrative Agent’s Permitted Discretion.
		
		  	“Permitted Discretion” shall mean a determination made in good faith and in the exercise of reasonable (from the perspective of a secured asset-based lender) business judgment, provided that any reserve
established or modified and any standard of eligibility shall have a reasonable relationship to circumstances, events or conditions which are the basis for such standard of eligibility.
		
		  	The Borrowing Base will be computed monthly by the ABL Borrowers and a certificate (the “Borrowing Base Certificate”) presenting the ABL Borrowers’ computation of the Borrowing Base (together with agings,
other collateral reporting (if any) to be agreed upon and if any Eligible Inventory has been included in the Borrowing Base, inventory reports) will be delivered to the Administrative Agent promptly, but in no event later than the twentieth calendar
day following the end of each calendar month; provided that (i) upon the occurrence and during the continuance of an Event of Default, (ii) or if Excess Availability (as defined below) is less than the greater of (x) 12.5% of Line Cap and (y)
$6 million (and continuing until Excess Availability has been greater than the greater of (x) 12.5% of Line Cap and (y) $6 million for a period of 30 consecutive days), the ABL Borrowers will be required to compute the Borrowing Base and deliver a
Borrowing Base Certificate on a weekly basis.
		
		  	“Excess Availability” means at any time an amount equal to (a) the Line Cap minus (b) the sum of the aggregate outstanding amount of ABL Loans, unreimbursed drawings under Letters of Credit and the undrawn
amount of outstanding Letters of Credit under the ABL Facility.
		
		  	
		
	Letters of Credit:	  	Subject to the Borrowing Base, up to an amount to be agreed of the ABL Facility shall be available for the issuance of letters of credit (the “Letters of Credit”) for the account of the ABL Borrowers and their
subsidiaries by the Administrative Agent and other consenting ABL Lenders under the ABL Facility reasonably satisfactory to the ABL Borrowers and the Administrative Agent (in such capacity, each an “Issuing Lender”); provided
that neither DBNY nor Barclays shall be required to issue any Letters of Credit other than standby letters of credit. No Letter of Credit shall have an expiration date after the earlier of (a) one year after the date of issuance unless
		
		  	

  
 Exhibit B - 4 

			
		  	consented to by the Issuing Lender and (b) five business days prior to the ABL Termination Date; provided that any Letter of Credit with a one-year tenor may provide for the renewal thereof for additional one-year periods
pursuant to procedures as set forth in the ABL Documentation with the applicable Issuing Lender (which shall in no event extend beyond the date referred to in clause (b) above). Letters of Credit shall be issued in U.S. Dollars. Drawings
under any Letter of Credit shall be reimbursed by the ABL Borrowers (whether with their own funds or with the proceeds of ABL Loans) on the same day if notice of such drawing is received by MKS from the relevant Issuing Lender before 11:00 a.m. (New
York City time), and otherwise on the next business day. To the extent that the ABL Borrowers do not so reimburse the Issuing Lender, the ABL Lenders under the ABL Facility shall be irrevocably and unconditionally obligated to fund participations in
the reimbursement obligations on a pro rata basis.
		
	Use of Proceeds:	  	The proceeds of the ABL Loans shall be used by the ABL Borrowers to provide for ongoing working capital requirements and for general corporate purposes, including permitted acquisitions, investments and restricted payments
permitted under the ABL Documentation.
		
	 B.     Incremental Facilities:
	  	
		
		  	The ABL Documentation shall permit the ABL Borrowers to increase commitments under the ABL Facility on the same terms (other than upfront fees) as the ABL Facility (any such increase, an “Incremental Facility”)
in an aggregate principal amount of $50 million; provided that (i) no ABL Lender will be required to participate in any such Incremental Facility, (ii) no event of default exists or would exist after giving effect thereto and (iii) the
representations and warranties in the ABL Documentation shall be true and correct in all material respects (and in all respects if qualified by materiality) immediately prior to, and after giving effect to, the incurrence of such Incremental
Facility.
		
	 3.      CERTAIN PAYMENT PROVISIONS
	  	
		
	Interest Rate Options:	  	The ABL Borrowers may elect that the ABL Facility comprising each borrowing bear interest at a rate per annum equal to (a) the ABR plus the Applicable Margin or (b) the Eurodollar Rate, plus the Applicable
Margin.
		
		  	As used herein:
		
		  	“ABR” means the highest of (i) the rate of interest last quoted by The Wall Street Journal as the “Prime Rate” in the U.S. or, if The Wall Street Journal ceases to quote such rate, the highest
per

  
 Exhibit B - 5 

			
		 	annum interest rate published by the Federal Reserve Board in Federal Reserve Statistical Release H.15 (519) (Selected Interest Rate) as the “bank prime loan” rate or, if such rate is no longer quoted therein,
any similar rate quote therein (as determined by the Administrative Agent) or similar release by the Federal Reserve Board (as determined by the Administrative Agent) (the “Prime Rate”), (ii) the federal funds effective rate from
time to time (which rate, if negative, shall be deemed to be 0.00%) plus 0.50% and (iii) the Eurodollar Rate applicable for an interest period of one month plus 1.00%.
		
		 	“ABR Loans” means Loans bearing interest based upon the ABR.
		
		 	“Applicable Margin” means, initially, (i) 0.75%, in the case of ABR Loans and (ii) 1.75%, in the case of Eurodollar Loans. Beginning on the date of the first interest period occurring after the date on
which the ABL Borrowers deliver to the ABL Lenders financial statements for the first full fiscal quarter after the Closing Date, the applicable margin for the ABL Facility will be determined based on average daily Excess Availability for the
previous fiscal quarter, as set forth below:

  

									
	 Average Excess Availability

(percentage of Commitments)
	  	Applicable Margin for Adjusted
LIBOR rate loans	 	 	Applicable Margin for ABR	 
	 > 66%
	  	 	1.50	% 	 	 	0.50	% 
	 £ 66% but > 33%
	  	 	1.75	% 	 	 	0.75	% 
	 £ 33%
	  	 	2.00	% 	 	 	1.00	% 

  

			
		  	“Eurodollar Loans” means Loans bearing interest based upon the Eurodollar Rate (as defined below).
		
		  	“Eurodollar Rate” means the rate (adjusted for statutory reserve requirements for eurocurrency liabilities) for eurodollar deposits for a period equal to one, two, three or six months or any longer period agreed
to by all relevant lenders (as selected by the ABL Borrowers) appearing on the page of the Reuters Screen which displays an average ICE Benchmark Administration Interest Settlement Rate or any successor substitute page (such page currently being
LIBOR01 page) (which rate, if negative, shall be deemed to be 0.00%).
		
	Interest Payment Dates:	  	In the case of ABR Loans, quarterly in arrears.
		
		  	In the case of Eurodollar Loans, on the last day of each relevant interest period and, in the case of any interest period longer than three months, on each successive date three months after the first day of such interest
period.

  
 Exhibit B - 6 

			
	Commitment Fees:	  	The ABL Borrowers shall pay a commitment fee calculated at a rate per annum equal to 0.375% on the average daily unused portion of the ABL Facility, with a step-down to 0.25% if on the last day of any fiscal quarter
(starting with the first full fiscal quarter after the Closing Date) the daily average unused portion of the ABL Facility during the preceding quarter was not more than 50% of the average daily amount of the aggregate commitments under the ABL
Facility during such period. Letters of Credit issued under the ABL Facility shall be deemed to be a utilization of the ABL Facility.
		
	Letter of Credit Fees:	  	The ABL Borrowers shall pay a fee on all outstanding Letters of Credit at a per annum rate equal to the Applicable Margin then in effect with respect to Eurodollar Loans, under the ABL Facility on the face amount of each
such Letter of Credit. Such fee shall be shared ratably among the ABL Lenders, and shall be payable quarterly in arrears on the last business day of each calendar quarter. A fronting fee in an amount equal to 0.125% on the face amount of each Letter
of Credit shall be payable quarterly in arrears on the last business day of each calendar quarter to the Issuing Lender for its own account. In addition, customary administrative, issuance, amendment, payment and negotiation charges shall be payable
to the Issuing Lender for its own account.

  

			
	Default Rate:	  	At any time when any Loan Party is in default in the payment of any amount under the ABL Facility, after giving effect to any applicable grace period, such overdue amounts shall bear interest at 2.00% per annum above
the rate otherwise applicable thereto, and with respect to any overdue amount (including overdue interest) for which there is no applicable rate, 2.00% per annum in excess of the rate otherwise applicable to ABL Loans maintained as ABR
Loans from time to time.
		
	Rate and Fee Basis:	  	All per annum rates shall be calculated on the basis of a year of 360 days (or 365/366 days, in the case of ABR Loans) for actual days elapsed.
		
	Optional Prepayments and	  	
	Commitment Reductions:	  	The Loans may be prepaid, in whole or in part without premium or penalty, in minimum amounts set forth in the ABL Documentation, at the option of the ABL Borrowers at any time upon one business day’s (or, in the case of a
prepayment of Eurodollar Loans, three business days’) prior notice, subject to reimbursement of the ABL Lenders’ redeployment costs in the case of a prepayment of Eurodollar Loans prior to the last day of the relevant interest period.
Optional prepayments of the ABL Loans, together with accrued interest, if any, shall be applied as directed by the ABL Borrowers (and absent such direction, in direct order of maturity thereof).

  
 Exhibit B - 7 

			
	Mandatory Prepayments:	  	If at any time the amounts outstanding under the ABL Facility (including outstanding Letters of Credit) exceed the Line Cap as in effect at such time, the ABL Borrowers will be required to make a mandatory prepayment in an amount
equal to such excess, to be applied (i) first, to prepayments of loans under the ABL Facility (with no reduction to the commitments under the ABL Facility) and (ii) to the extent in excess thereof, to cash collateralize outstanding Letters of
Credit. Mandatory repayments of loans under the ABL Facility shall not reduce the commitments under the ABL Facility.
		
		  	 Upon any sale or other disposition of any assets of any Loan Party, in each case to the extent constituting ABL Priority Collateral,
outside of the ordinary course of business or the receipt by the Loan Parties and their restricted subsidiaries of any proceeds from casualty insurance or a condemnation of ABL Priority Collateral (in each case, with exceptions and materiality
levels to be agreed in the ABL Documentation), above a threshold to be agreed, the ABL Borrowers shall provide an updated calculation of the Borrowing Base.
  

If a Cash Dominion Event (as defined below) has occurred and is continuing, all amounts deposited in each Collection Account (as defined below) will be
promptly applied by the Administrative Agent to repay outstanding loans under the ABL Facility and, if an event of default exists, to cash collateralize outstanding Letters of Credit.

	 4.      COLLATERAL
	  	
		
	Collateral:	  	 Subject to exclusions and limitations as set forth in the ABL Documentation and subject to customary funding conditions, the obligations
of the ABL Borrowers and each Guarantor in respect of the ABL Facility and any swap agreements and cash management arrangements provided by any ABL Lender or Arranger (or any affiliate of a ABL Lender or Arranger) shall be secured by (a) a perfected
first-priority security interest in all of the ABL Priority Collateral (as defined in Exhibit A) and (b) a perfected second-priority security interest (subject to permitted liens) in all of the Term Priority Collateral (as defined in Exhibit A).

 
 Notwithstanding anything to the contrary, the Collateral shall exclude (or not require
actions with respect thereto as described below) the Excluded Assets (as defined in Exhibit A).

  
 Exhibit B - 8 

			
		  	None of the Collateral shall be subject to any other pledges, security interests or mortgages, except junior liens on ABL Priority Collateral and other liens on other Collateral in each case as permitted under the lien covenant.
Notwithstanding the foregoing, no foreign law governed documents or foreign law opinions shall be required in connection with the ABL Documentation.
		
	Intercreditor Agreement:	  	The relative rights and priorities in the Collateral among the ABL Lenders, on the one hand, and the Term Lenders, on the other hand, will be set forth in the intercreditor agreement that is reasonably acceptable to the
Administrative Agent under each Facility and the Loan Parties (the “Intercreditor Agreement”).
		
	Cash Management:	  	The Loan Parties shall use commercially reasonable efforts to, prior to the Closing Date (and in any event within 90-days after the Closing Date (which period may be extended by the Administrative Agent in its reasonable
discretion)), implement cash management arrangements reasonably acceptable to the Administrative Agent, including control agreements providing for springing dominion over deposit and securities accounts of Loan Parties in favor of the Collateral
Agent, subject to customary exclusions to be agreed. Collections and proceeds from the ABL Priority Collateral shall be deposited directly into an account with the Administrative Agent or another financial institution reasonably acceptable to the
Administrative Agent (it being acknowledged and agreed that Bank of America is reasonably acceptable) and subject to such account control arrangements (each, a “Controlled Account”).
		
		  	As used herein, “Cash Dominion Event” shall mean either (i) the occurrence and continuance of an Event of Default, or (ii) Excess Availability is less than the greater of (x) 10% of Line Cap and (y) $5 million
for three (3) consecutive business days (and continuing until Excess Availability has been greater than the greater of (x) 10% of Line Cap and (y) $5 million for a period of 30 consecutive days). Upon and during the continuance of a Cash Dominion
Event, collections and proceeds from the ABL Priority Collateral received by the Loan Parties in a Controlled Account shall be remitted daily to a collection account maintained by the Administrative Agent for application to outstanding loans under
the ABL Facility.
		
	 5.      CONDITIONS
	  	
		
	Conditions to Initial Borrowing:	  	The extension of credit under the ABL Facility on the Closing Date will be subject only to the conditions precedent set forth in Exhibit C to the Commitment Letter.

  
 Exhibit B - 9 

			
	Conditions after Closing Date:	  	The making of each extension of credit under the ABL Facility after the Closing Date shall be conditioned upon (a) delivery of a customary borrowing notice, (b) the accuracy of representations and warranties in all material
respects, (c) the absence of defaults or events of default at the time of, or after giving effect to the making of, such extension of credit and (d) the existence of Excess Availability at least in the amount of the requested credit
extension.

event of default has occurred and is continuing or Excess Availability is less than the greater of (1) 10% of Line Cap and (2) $5 million, in any such event (a “Trigger Event”), and (y) upon the occurrence of a Trigger Event, such
covenant shall be only tested as of the last day of the most recent fiscal quarter end for the twelve months then ended for which financial statements were required to be delivered and as of each fiscal quarter end thereafter until the Trigger Event
is cured for a period of 30 consecutive days following the Trigger Event.

  
 Exhibit B - 10 

			
	Unrestricted Subsidiaries:	  	The ABL Documentation contains provisions pursuant to which, subject to limitations on investments, loans, advances and guarantees and other customary conditions and provisions as set forth in the ABL Documentation, the ABL

	Voting, Assignments and	  	
	Participations, Yield Protection:	  	After the Closing Date, the ABL Lenders shall be permitted to assign loans and commitments under the ABL Facility with the consent of MKS (not to be unreasonably withheld or delayed) and the Issuing Lenders (in each case,

(ii) for assignments of loans and commitments to another ABL Lender under the ABL Facility or to an affiliate or approved fund of a ABL Lender under the ABL Facility. All assignments will require the consent of the Administrative Agent and the
Issuing Lenders (in each case not to be unreasonably withheld or delayed) unless such assignment is an assignment of the ABL Loans to another ABL Lender under the ABL Facility or to an affiliate or approved fund of an ABL Lender under the ABL
Facility. Each assignment will be in

  
 Exhibit B - 15 

			
		
		 	an amount of an integral multiple as set forth in the ABL Documentation or, in each case, if less, all of such ABL Lender’s remaining loans and commitments of the applicable class. Natural persons and the ABL Borrowers,
their subsidiaries and affiliates may not be assignees.
		
		 	 The ABL Lenders are permitted to sell participations in Loans and commitments without restriction, other than as set forth in the next
sentence, and in accordance with applicable law. Voting rights of participants shall be limited to matters in respect of (a) increases in commitments participated to such participants, (b) reductions of principal, interest or fees,
(c) extensions of final maturity and (d) releases of all or substantially all of the value of the Guarantees or all or substantially all of the Collateral.
  

Amendments and waivers with respect to the ABL Documentation shall require the approval of ABL Lenders holding more than 50% of the aggregate amount Loans
and commitments under the ABL Facility (the “Required Lenders”), except that (a) in addition to the consent of the Required Lenders, the consent of each ABL Lender directly affected thereby shall be required with respect to
(i) reductions in the amount or extensions of the scheduled date of any amortization or final maturity of any Loan and (ii) reductions in the rate of interest or any fee or extensions of any due date thereof (but, for the avoidance of
doubt, other than default rate interest) and (iv) increases in the amount or extensions of the expiry date of any ABL Lender’s commitment, (b) the consent of 100% of the ABL Lenders shall be required with respect to

be required with respect to votes for changes to the definition of “Borrowing Base” or any component definition thereof, or changes in advance rates, the effect of which is to increase availability thereunder.

 
 The ABL Documentation contains customary provisions for replacing non-consenting ABL
Lenders in connection with

  
 Exhibit B - 16 

			
		  	amendments and waivers requiring the consent of all ABL Lenders or of all ABL Lenders directly affected thereby so long as the Required Lenders shall have consented thereto.
		
		  	The ABL Documentation shall contain customary protective provisions for such matters as EU bail-in, capital adequacy, increased costs, reserves, funding losses, illegality, and withholding taxes, including treatment of Dodd-Frank
Wall Street Reform and Consumer Protection Act and Basel III as changes in law.
		
	Defaulting Lenders:	  	The ABL Documentation will include customary defaulting lender provisions to protect the Administrative Agent and the Issuing Lenders with respect to the funding and reimbursement obligations of defaulting lenders. The ABL
Borrowers will not be required to pay certain fees to any defaulting lender and the voting rights of defaulting lenders (except in the case of certain customary matters) shall be suspended. Upon any ABL Lender becoming a defaulting lender, the
outstanding Letters of Credit shall be reallocated among non-defaulting lenders under the ABL Facility (up to their respective commitments) and, to the extent any Letter of Credit exposure remains unallocated, the ABL Borrowers shall be required to
post cash collateral in the amount of the product of (x) the face amount of the issued Letters of Credit multiplied by (y) the unallocated commitment percentage of defaulting lenders. A defaulting lender is a lender who has failed to perform certain
of its obligations under the ABL Documentation or has become insolvent or is in receivership as more fully set forth in the ABL Documentation. The loans and commitments of defaulting lenders shall not be counted toward the calculation of the
Required Lenders or Supermajority Lenders.
		
	Expenses and Indemnification:	  	The ABL Borrowers shall pay (a) all reasonable and documented or invoiced out-of-pocket expenses of the Administrative Agent and the Arrangers in connection with the syndication of the ABL Facility and the preparation, execution,
delivery and administration of the ABL Documentation and any amendment or waiver with respect thereto (including, without limitation, the reasonable fees, disbursements and other charges of one primary counsel, one local counsel in each relevant
jurisdiction and counsel otherwise retained with the ABL Borrowers’ consent) and (b) all reasonable and documented or invoiced out-of-pocket expenses of the Administrative Agent, the Arrangers and the ABL Lenders (including, without limitation,
the fees, disbursements and other charges of counsel) in connection with the enforcement of the ABL Documentation.

  
 Exhibit B - 17 

			
		  	The Loan Parties will indemnify the Administrative Agent, each Issuing Lender, the Arrangers and the ABL Lenders and their respective affiliates, and the officers, directors, employees, affiliates, agents and controlling persons

respective affiliates, creditors or shareholders) that relate to the ABL Documentation), except to the extent that it is found by a final, non-appealable judgment of a court of competent jurisdiction that such loss, claim, damage, liability or

arising as a result of any act or omission by any ABL Borrower or any of its subsidiaries or affiliates) other than any claim, action, suit, inquiry, litigation, investigation or other proceeding brought by or against any such indemnified party in
its capacity as agent or arranger.

MKS Instruments, Inc. 

$800.0 million Term Loan Facility 

$50.0 million ABL Facility 

Summary of Terms and Conditions 

Capitalized terms used in this Exhibit C shall have the meanings set forth in the Commitment Letter to which this Exhibit C is
attached and the other Exhibits to the Commitment Letter. The commitments of the Initial Lenders and the Arrangers’ and other agents’ agreements to perform the services described herein (including the initial borrowing under the
Facilities) are subject only to the satisfaction (or waiver by the Arrangers) of the following conditions precedent: 
 1. Subject to the Certain Funds
Provision and the Documentation Principles, definitive loan documentation for the Facilities consistent with the Term Sheets and the Commitment Letter (including, without limitation, the Guarantees and Collateral to the extent required by the Term
Sheets and the Commitment Letter) shall have been executed and delivered by the parties thereto to the Administrative Agents. 
 2. The Acquisition shall
have been, or substantially concurrently with the initial borrowing under the Facilities shall be, consummated in all material respects in accordance with the Acquisition Agreement. No material provision of the Acquisition Agreement shall have been
waived, amended or otherwise modified in a manner material and adverse to the Lenders (in their capacity as such) or the Arrangers without the consent of the Arrangers; provided that (a) any reduction in the purchase price for the
Acquisition set forth in the Acquisition Agreement shall not be deemed to be material and adverse to the interests of the Lenders or the Arrangers so long as any such reduction is applied to reduce the amount of commitments in respect of the Term
Loan Facility on a dollar-for-dollar basis and (b) any increase in the purchase price set forth in the Acquisition Agreement shall be deemed to be not material and adverse to the interests of the Lenders or the Arrangers so long as such
purchase price increase is not funded with additional indebtedness (it being understood and agreed that no purchase price, working capital or similar adjustment provisions set forth in the Acquisition Agreement shall constitute a reduction or
increase in the purchase price). 
 3. The Arrangers shall have received (a) audited consolidated balance sheets and related statements of income,
changes in equity and cash flows of each of the Borrower and of the Company for the three fiscal years ended at least 60 days prior to the Closing Date (as defined in Exhibit A and used in Exhibit C, the “Closing Date”) and
(b) unaudited consolidated balance sheets and related statements of income, changes in equity and cash flows of each of the Borrower and of the Company for each subsequent fiscal quarter following the last fiscal year for which financial
statements have been delivered pursuant to clause (a) above ended at least 40 days before the Closing Date. 
 4. The Arrangers shall have received a
pro forma consolidated balance sheet and the related consolidated statement of income of the Borrower as of and for the twelve-month period ending on the date of the most recent consolidated balance sheet delivered pursuant to the preceding
paragraph, in each case prepared after giving effect to the Transactions as if the Transactions had occurred on such date (in the case of such pro forma balance sheet) or on the first day of such period (in the case of such pro forma statement of
income) which need not be prepared in compliance with Regulation S-X of the Securities Act of 1933, as amended, or include adjustments for purchase accounting (including adjustments of the type contemplated by Financial Accounting Standards Board
Accounting Standards Codification 805, Business Combinations (formerly SFAS 141R)). 

 5. The Refinancing shall have been (or substantially simultaneously with the closing under the Acquisition, shall
be) consummated. After giving effect to the Refinancing and the other transactions contemplated hereby, the Borrower and its subsidiaries shall have outstanding no indebtedness (other than the loans and other extensions of credit under the
Facilities and (x) as to the Acquired Business, indebtedness permitted to remain outstanding on and after the Closing Date under the Acquisition Agreement and (y) as to the Borrower and its other subsidiaries, deferred purchase price
obligations, ordinary course working capital facilities for foreign subsidiaries and ordinary course capital lease, purchase money and equipment financings), and Borrower shall not have any outstanding equity that is mandatorily redeemable at the
option of the holder earlier than the date that is 90 days after the Term Maturity Date. 
 6. Subject to the Certain Funds Provision, the Administrative
Agents shall have received (a) all documents and instruments required to create and perfect each Collateral Agent’s security interest in the Collateral, executed and delivered by the applicable Loan Parties, (b) a reasonably
satisfactory certificate substantially in the form of Annex I to the Commitment Letter attesting to the solvency of the Borrower and its subsidiaries on the Closing Date (as defined in Exhibit A) on a consolidated basis after giving effect to the
Transactions from the chief financial officer or another senior financial officer of the Borrower, (c) a borrowing base certificate in respect of the ABL Facility and (d) such legal opinions, certificates, organizational documents,
borrowing notice and instruments as are customary for transactions of this type. 
 7. Since the date of the Acquisition Agreement, there shall not have
occurred any event, change, occurrence or effect that, individually or in the aggregate, has had or would reasonably be expected to have a Material Adverse Effect (as defined in the Acquisition Agreement, a “Company Material Adverse
Effect”). 
 8. All accrued costs, fees and expenses (including legal fees and expenses and the fees and expenses of any other advisors) and other
compensation due and payable to the Administrative Agents, the Arrangers and the Lenders shall have been paid, to the extent an invoice therefor was presented at least two business days prior to the Closing Date (or such later date as the Borrower
may agree). 
 9. The Loan Parties shall have provided the documentation and other information to the Lenders required by regulatory authorities under the
applicable “know-your-customer” rules and regulations, including the PATRIOT Act, in each case at least three business days prior to the Closing Date, as has been requested to the Borrower in writing at least ten business days prior to the
Closing Date. 
 10. The Arrangers shall have been provided with a period of at least 15 consecutive business days (ending no later than the business day
immediately prior to the Closing Date) following the receipt of the such information as is requested by the Arrangers and customarily delivered by a borrower and necessary for the preparation of a customary Confidential Information Memoranda to
syndicate the Facilities; provided that such period will not include July 4, 2016 or any date from and including August 22, 2016 through and including September 5, 2016. If the Borrower in good faith reasonably believes it has
delivered the information requested by the Arrangers in accordance with the preceding sentence for use in the Confidential Information Memorandum, it may deliver to the Arrangers a written notice to that effect, in which case the Confidential
Information Memorandum will be deemed to have been delivered on the date such notice is received by the Arrangers, and the 15 consecutive business day period referred to above will be deemed to have commenced on the date such notice is received by
the Arrangers, in each case, unless the Arrangers in good faith reasonably believe that the Borrower has not completed delivery of the information requested by the Arrangers in accordance with the preceding sentence for use in the Confidential
Information Memorandum and, within 3 business days after the receipt of such notice from the Borrower, the Arrangers deliver a written notice to the Borrower to that effect (stating with reasonable specificity which information required to be
included in the Confidential Information Memorandum has not been delivered). 

 11. The Specified Representations and the Specified Acquisition Agreement Representations shall be true and
correct in all material respects (except for representations and warranties that are already qualified by materiality, which representations and warranties shall be true and correct in all respects after giving effect to such materiality
qualification) on the Closing Date.

Pursuant to Section [    ] of the Credit
Agreement1, the undersigned, solely in the undersigned’s capacity as [chief financial officer][specify other officer with equivalent duties] of the Borrower,

of the Loans under the Credit Agreement on the Closing Date and the application of the proceeds thereof): 
  

	 	(a)	the fair value of the assets of the Borrower and its Subsidiaries, on a consolidated basis, exceeds their debts and liabilities, subordinated, contingent or otherwise, on a consolidated basis; 

 

	 	(b)	the present fair saleable value of the property of the Borrower and its Subsidiaries, on a consolidated basis, is greater than the amount that will be required to pay the probable liability, on a consolidated basis, of
their debts and other liabilities, subordinated, contingent or otherwise, on a consolidated basis, as such debts and other liabilities become absolute and matured; 

 

	 	(c)	the Borrower and its Subsidiaries, on a consolidated basis, are able to pay their debts and liabilities, subordinated, contingent or otherwise, on a consolidated basis, as such liabilities become absolute and matured;
and 

  

	 	(d)	the Borrower and its Subsidiaries, on a consolidated basis, are not engaged in, and are not about to engage in, business for which they have unreasonably small capital. 

For purposes of this Solvency Certificate, the amount of any contingent liability at any time shall be computed as the amount that would
reasonably be expected to become an actual and matured liability. Capitalized terms used but not otherwise defined herein shall have the meanings assigned to them in the Credit Agreement. 

The undersigned is familiar with the business and financial position of the Borrower and its Subsidiaries. In reaching the conclusions set
forth in this Solvency Certificate, the undersigned has made such investigations and inquiries as the undersigned has deemed appropriate, having taken into account the nature of the business proposed to be conducted by the Borrower and its
Subsidiaries after consummation of the Transactions.

HEI Exhibit 4.7(a)
AMENDMENT 2013-1 TO THE
AMERICAN SAVINGS BANK 401(k) PLAN
The following amendments to the American Savings Bank 401(k) Plan (the “Plan”) add a Roth 401(k) contribution feature and a Roth in-Plan conversion feature.  These amendments are effective January 1, 2014.
		
	1.
	A new Section 2.1.A is added to read as follows:

2.1.A    Roth 401(k) Contributions.  A Participant making a 401(k) election in accordance with Section 1.1(a)(ii) may designate all or a portion of the Participant’s 401(k) Contributions as Roth 401(k) Contributions if the following conditions are satisfied:
(a)Irrevocable Election.  The Participant’s designation must be made before the 401(k) Contributions are withheld from the Participant’s Compensation in accordance with procedures approved by the Administrative Committee.  Once Roth 401(k) Contributions are withheld from the Participant’s Compensation, the designation is irrevocable.  However, the election may be changed with respect to future 401(k) Contributions in accordance with Section 1.1(a)(ii) (setting forth the Plan’s normal rules for changes in 401(k) elections).  To the extent a Participant does not affirmatively designate 401(k) Contributions as Roth 401(k) Contributions, such contributions shall constitute pre-tax 401(k) Contributions.
(b)After-Tax Treatment by the Participating Employers.  The Participating Employers shall treat any Roth 401(k) Contributions as includible in the Participant’s income (i.e., treat as wages subject to applicable income and employment tax withholding) at the time the Participant would have received the contributed amounts in cash but for the Roth 401(k) election.
(c)Separate Accounting.  In accordance with Section 4.2, the Trustee or an affiliate of the Trustee shall establish and maintain a Roth Contribution Subaccount (by whatever name or designation the Trustee deems appropriate) for each Participant who elects to make Roth 401(k) Contributions to the Plan.  The Roth Contribution Subaccount shall include a record of the Participant’s “investment in the contract” (i.e., Roth 401(k) Contributions that have not been distributed).  Gains, income, losses, and other credits or charges shall be separately allocated on a reasonable and consistent basis among the Roth Contribution Subaccounts and all other Subaccounts.  However, no forfeitures shall be allocated to any Roth Contribution Subaccount.  The separate accounting requirement described in this paragraph shall 

be applicable at the first time any Roth 401(k) Contribution is made and shall continue until the Roth Contribution Subaccount is completely distributed.
(a)Coordination with 401(k) Contribution Rules.  Except as otherwise provided hereunder, the Participant’s Roth 401(k) Contributions shall be subject to all Plan requirements applicable to 401(k) Contributions.  For example, except as otherwise provided hereunder, the Roth 401(k) Contributions shall constitute 401(k) Contributions for purposes of: (i) the election procedures in Section 1.1(a)(ii), (ii) the nondiscrimination tests and rules under Section 3.1, (iii) the calendar-year dollar limitation under Section 402(g) of the Code and Section 3.2 of the Plan ($17,500 in 2013), (iv) the Catch-up Contribution provisions in Section 414(v) of the Code and Sections 2.1(b) and 3.2(b) of the Plan, (v) the allocation of AmeriMatch Contributions under the Plan; (vi) the limitations under Section 415(c) of the Code that are described in Section 3.4 of the Plan, (vii) the minimum distribution rules in Section 401(a)(9) of the Code and Section 6.7 of the Plan, (viii) full vesting of 401(k) Contributions under Article V, and (ix) the determination of Top-Heavy Plan status under Article XI.
2.A new Section 2.5(d) is added to read as follows.
(d)    Direct Rollovers from Designated Roth Accounts.  A Participant or an Eligible Employee may make a direct rollover from a designated Roth account in another tax-qualified 401(k) plan or 403(b) annuity or governmental 457(b) plan.  The Trustee shall separately account for any Roth contributions rolled over to the Plan.  Rollover contributions are not permitted from Roth IRAs.
3.A new Section 3.1(c)(vi) is added to read as follows:
(vi)    Special Rule for Roth 401(k) Contributions.  To the extent excess contributions are distributed to an HCE under this Section 3.1(c) for a Plan Year that includes both pre-tax 401(k) Contributions and Roth 401(k) Contributions, the excess contributions shall be distributed in the following order of priority: (A) first, any pre-tax 401(k) Contributions shall be distributed, and (B) second, Roth 401(k) Contributions shall be distributed.  In accordance with Treasury Regulations, the principal amount of any Roth 401(k) Contributions shall not be includible in gross income, but any income allocable to the distribution shall be includible in gross income.

2

4.A new Section 3.2(a)(iv) is added to read as follows:
(iv)    Special Rule for Roth 401(k) Contributions.  To the extent excess elective deferrals are distributed under Section 3.2(a)(ii) for a Plan Year that includes both pre-tax 401(k) Contributions and Roth 401(k) Contributions, the excess elective deferrals shall be distributed in the following order of priority: (A) first, any pre-tax 401(k) Contributions shall be distributed, and (B) second, Roth 401(k) Contributions shall be distributed.  In accordance with Treasury Regulations, the principal amount of any Roth 401(k) Contributions shall not be includible in gross income, but any income allocable to the distribution shall be includible in gross income.
5.A new sentence is added at the end of Section 4.5(b) to read as follows:
A Participant’s Roth Contribution Subaccount or Roth In-Plan Conversion Subaccount (defined in Section 6.10.A) will be included in determining a Participant’s maximum loan amount and are available sources for loans.
6.A new Section 6.10(d) is added to read as follows:
(d)Special Rules for Direct Rollovers from Roth Contribution Subaccounts.  For purposes of applying this Section 6.10 to Roth Contribution Subaccounts, the following special rules shall apply:
(i)The $200 threshold for Eligible Rollover Distributions in Section 6.10(a)(i)(D) shall be applied separately to a Participant’s Roth Contribution Subaccount and to the remainder of a Participant’s Account.
(ii)A Direct Rollover from a Roth Contribution Subaccount may be made only to a Roth IRA (a Roth individual retirement account or Roth individual retirement annuity) or a designated Roth account in (A) a qualified retirement plan described in Code Section 401(a), (B) an annuity contract described in Code Section 403(b), or (C) an eligible deferred compensation plan under Code Section 457(b) that is maintained by a state, a political subdivision of a state, or any agency or instrumentality of a state or political subdivision of a state, that will accept the Direct Rollover.
(iii)The Plan Administrator must provide a 402(f) Notice that describes rollover rights with respect to the Participant’s Roth Contribution Subaccount.

3

7.A new Section 6.10.A is added to read as follows:
Section 6.10.A     Roth In-Plan Conversions
After a Participant has had a distributable event (e.g., attainment of age 591⁄2 or severance from employment), the Participant may make a direct rollover of the vested portion of any Subaccount (other than a Roth Contribution Subaccount) to a separate account established by the Trustee (a “Roth In-Plan Conversion Subaccount”).  The direct rollover will be subject to income tax at the time of rollover to the same extent as a direct rollover outside of the Plan to a Roth IRA.  A Roth in-Plan conversion is permitted only for active and terminated, vested Participants and only with respect to an amount that would be an Eligible Rollover Distribution, as defined in Section 6.10(a)(i) above, if it were distributed or rolled over outside of the Plan.  Surviving spouses, other Beneficiaries, and alternate payees may not make Roth in-Plan conversions.  If a Participant has an outstanding Plan loan, the loan balance is not eligible for Roth in-Plan conversion.  Before a Participant makes a Roth in-Plan conversion, the Plan Administrator must provide the Participant with a 402(f) Notice that describes the tax effects of a Roth in-Plan conversion.  An election to make a Roth in-Plan conversion is irrevocable once the direct rollover has been made.  Roth In-Plan Conversion Subaccounts are subject to the same distribution and withdrawal rules and restrictions as Roth Contribution Subaccounts.
8.Section 12.16 is restated in its entirety to read as follows:
12.16    “401(k) Contributions” means a Participant’s elective contributions described in Sections 2.1 and 2.1.A.  401(k) Contributions are comprised of three components: Regular 401(k) Contributions, Roth 401(k) Contributions, and Catch-up Contributions.
9.The following definition is added in Article XII:
“Qualified Roth Distribution” means a distribution from a Roth Contribution Subaccount that is made after the Participant attains age 591⁄2 (or because of the death or Disability of the Participant) and after the five-taxable-year period (i.e., five consecutive calendar years) beginning January 1 of the first year in which the Participant made a designated Roth 401(k) Contribution to the Plan.
