 WHEREAS, each Loan Party
under the Existing Credit Agreement expects to realize substantial direct and indirect benefits as a result of this Agreement becoming effective and the consummation of the transactions contemplated hereby and agrees to reaffirm its obligations

 WHEREAS, the
Borrower has requested that the Existing Credit Agreement be amended as set forth herein; 
 WHEREAS, the undersigned, constituting
the Supermajority Lenders, are willing to agree to such amendments as set forth herein; 
 NOW, THEREFORE, in consideration of the
premises and agreements, provisions and covenants herein contained, the parties hereto agree as follows: 
  

	1.	 Credit Agreement Amendments. Effective as of the Amendment No. 1 Effective Date, the
Existing Credit Agreement is hereby amended as follows: 


 The definition of “Borrowing Base” in the Existing
Credit Agreement is hereby amended and restated in its entirety as follows: 
 “Borrowing Base” means (a) the sum of 85% of
Eligible Accounts of the Loan Parties; plus (b) either (i) with respect to any calculation conducted at any time prior to the completion of Administrative Agent’s and its third-party consultants’ and representatives’ initial
field examination and appraisal of the Inventory of the Loan Parties after the Closing Date (it being understood that the Administrative Agent shall be permitted to conduct (or engage third parties to conduct) customary field examinations and
inventory appraisals on the Inventory in its Permitted Discretion at any such time, and such initial field examination and inventory appraisal shall constitute a field examination and/or appraisal, as applicable, contemplated by
Section 6.06(b)(i)), the lesser of (A) 20% of the net book value of Eligible Inventory of the Loan Parties located in the U.S. and (B) 30% of the Borrowing Base or (ii) with respect to any calculation conducted at any time thereafter, the
lesser of (A) the lesser of (x) 65% of the lower of cost or market value (on a first-in-first-out basis) of Eligible
Inventory of the Loan Parties and (y) 85% of the Net Orderly Liquidation Value of Eligible Inventory of the Loan Parties and (B) 30% of the Borrowing Base; minus (c) Reserves established by the Administrative Agent in the exercise of its
Permitted Discretion. The Administrative Agent shall have the right, acting within the Administrative Agent’s Permitted Discretion, (x) to modify eligibility standards upon three (3) Business Days’ prior notice to MKS and
(y) to establish and modify Reserves against the Borrowing Base upon three (3) Business Days’ prior notice to MKS (it being understood that on or after the third Business Day prior to the effectiveness of such establishment or
modification, solely for purposes of incurring any new Credit Extension, the Borrowing Base shall be calculated after giving effect to such establishment or modification of Reserves). 












 In connection with any Post-Closing Acquisition, MKS may submit a Borrowing Base Certificate
reflecting a calculation of the Borrowing Base that includes Eligible Accounts acquired in connection therewith (the “Acquired Eligible Accounts”) and, if Eligible Inventory has been included in the Borrowing Base pursuant to clause
(b) of this definition above, Eligible Inventory acquired in connection therewith (the “Acquired Eligible Inventory”). From and after the Acquisition Date (as defined below), the Borrowing Base hereunder shall be calculated giving
effect thereto; provided that prior to the occurrence of a Borrowing Base Examination with respect to such Acquired Eligible Accounts and Acquired Eligible Inventory, from the date such Post-Closing Acquisition is consummated (the “Acquisition
Date”) until the date that is 60 days after the Acquisition Date, the aggregate amount of Acquired Eligible Accounts and Acquired Eligible Inventory included in the Borrowing Base prior to the completion of a Borrowing Base Examination with
respect thereto shall not exceed 10% of the Borrowing Base (calculated after giving effect to the inclusion of the Acquired Eligible Accounts and Acquired Eligible Inventory as to which a Borrowing Base Examination has not occurred). From the 61st
day following the Acquisition Date (or such later day as the Administrative Agent may agree) with respect to any applicable Acquired Eligible Accounts and Acquired Eligible Inventory, the Borrowing Base shall be calculated without reference to such
Acquired Eligible Accounts and the Acquired Eligible Inventory until a Borrowing Base Examination has occurred with respect to such assets; it being understood and agreed that (x) no Default or Event of Default shall result from any failure for
a Borrowing Base Examination with respect to Acquired Eligible Accounts or Acquired Eligible Inventory to occur on or prior to the dates indicated above and (y) any such Borrowing Base Examination with respect to Acquired Eligible Accounts or
Acquired Eligible Inventory shall not count toward the limitations on the number of inventory appraisals and field examinations contained in Section 6.06(b).” 
  

	4.	 Effective Date Conditions. This Agreement will become effective on the date (the
“Amendment No. 1 Effective Date”), on which each of the following conditions have been satisfied in accordance with the terms therein:

and correct in all respects on the date of hereof and (ii) in the case of all other representations and warranties, true and correct in all material respects, in each case, on and as of the date hereof, in each case, except to the extent that
such representations and warranties specifically refer to an earlier date, in which case they shall be true and correct on the basis set forth above as of such earlier date;

Adverse Effect or (iii) violate any Law, except in any case for such violations that would not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect; 



 

	 	(c)	 this Agreement has been duly executed and delivered by each Loan Party that is party hereto, and this Agreement
constitutes a legal, valid and binding obligation of such Loan Party, enforceable against each Loan Party that is party thereto in accordance with its terms, except (i) as such enforceability may be limited by applicable bankruptcy, insolvency,
examinership, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and (ii) that rights of acceleration and the availability of equitable remedies may be limited by equitable principles of
general applicability (regardless of whether enforcement is sought by proceedings in equity or at law); and 


  

	 	(d)	 both immediately before and after giving effect to the Amendment No. 1 Effective Date, (i) the
representations and warranties of the Borrowers and the other Loan Parties contained in Article V of the Credit Agreement and in any other Loan Document shall be (A) in the case of representations and warranties qualified by
“materiality,” “Material Adverse Effect” or similar language, true and correct in all respects on the date of hereof and (B) in the case of all other representations and warranties, true and correct in all material respects,

earlier date and (ii) no Default or Event of Default shall have occurred and be continuing.

which it is a party are, and shall continue to be, in full force and effect and are hereby ratified and confirmed in all respects, in each case as amended by this Agreement. For greater certainty and without limiting the foregoing, each Loan Party
hereby confirms that the existing security interests granted by such Loan Party in favor of the Senior Credit Parties pursuant to the Loan Documents in the Collateral described therein shall continue to secure the obligations of the Loan Parties
under the Credit Agreement and the other Loan Documents as and to the extent provided in the Loan Documents. Except as specifically amended by this Agreement, the Credit Agreement and the other Loan Documents shall remain in full force.



  

	 	(b)	 The execution, delivery and performance of this Agreement shall not constitute a waiver of any provision of, or
