require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The words “include,” “includes” and “including” shall be deemed to be followed by the phrase
“without limitation.” The word “will” shall be construed to have the same meaning and effect as the word “shall.” Unless the context requires otherwise, (i) any definition of or reference to
any agreement, instrument or other document (including any Organization Document) shall be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any
restrictions on such amendments, supplements or modifications set forth herein or in any other Loan Document), (ii) any reference herein to any Person shall be construed to include such Person’s successors and assigns, (iii) the words
“herein,” “hereof” and “hereunder” and words of similar import when used in any Loan Document shall be construed to refer to such Loan Document in its entirety and not to any particular provision
thereof, (iv) all references in a Loan Document to Articles, Sections, Exhibits and Schedules shall be construed to refer to Articles and Sections of, and Exhibits and Schedules to, the Loan Document in which such references appear,

any specific reference to any definition, term or provision of the Term Credit Agreement as in effect on the Closing Date shall, at any time after the Closing Date, be deemed to include the provision of the Term Credit Agreement that, at such time,
corresponds to the relevant specifically-referenced provision of the Term Credit Agreement as in effect on the Closing Date. 

Section 1.03 Accounting Terms and Determinations. 

(a) Generally. All accounting terms not specifically or completely defined herein shall be construed in conformity with, and all
financial data (including financial ratios and other financial calculations) required to be submitted pursuant to this Agreement shall be prepared in conformity with, GAAP applied on a consistent basis, as in effect from time to time, except as
otherwise specifically prescribed herein, in any other Loan Document or as disclosed to the Administrative Agent. 
 (b) Changes in
GAAP. If at any time any change in GAAP would affect the computation of any financial ratio or requirement set forth in any Loan Document, and either (x) MKS or (y) within thirty (30) days after delivery of any financial
statements reflecting any change in GAAP (or after the Lenders have been informed of the change in GAAP affecting such financial statements, if later), the Administrative Agent or the Required Lenders shall so request, the Administrative Agent, the
Lenders and the Borrowers shall negotiate in good faith to amend such ratio or requirement to preserve the original intent thereof in light of such change in GAAP (subject to the approval of the Required Lenders); provided that, until so
amended, (i) such ratio or requirement shall continue to be computed in accordance with GAAP prior to such change therein and (ii) the Borrowers shall provide to the Administrative Agent and the Lenders financial statements and any other
documents required under this Agreement or as reasonably requested hereunder setting forth a reconciliation between calculations of such ratio or requirement made before and after giving effect to such change in GAAP. Notwithstanding any change in
GAAP before or after the Closing Date that would require lease obligations that would be characterized as operating leases as of the Term Loan Closing Date to be classified and accounted for as capital leases, finance leases or otherwise reflected
on the Loan Parties’ consolidated balance sheet, for the purposes of determining compliance with any covenant contained herein, such obligations shall be treated in the same manner as operating leases are treated as of the Term Loan Closing
Date and the foregoing reconciliation shall not be required. It is understood and agreed that, with respect to fiscal periods commencing on or after January 1, 2018, the impact of FASB ASC 606 and FASB ASC
340-40 on revenue recognition and amortization of associated costs and expenses shall be given effect for all purposes under this Agreement, and the foregoing reconciliation shall not be required. 

(c) Pro Forma Calculations. All pro forma computations required to be made in this Agreement and in any other Loan
Document giving effect to any Disposition, Permitted Acquisition, other Investment permitted hereunder, any merger and acquisition permitted hereunder, designation of any Subsidiary as an Unrestricted Subsidiary, redemption or repayment of
Indebtedness or issuance, incurrence or assumption of Indebtedness shall be calculated after giving pro forma effect thereto immediately after giving effect to such acquisition, disposition, Investment, designation, redemption or repayment of
Indebtedness, or issuance, incurrence or assumption of Indebtedness (and to any other such transaction consummated since the first day of the period for which such pro forma computation is being made and on or prior to the date of such
computation) as if such transaction (and any other such transactions) had occurred on the first day of the applicable Test Period, and, to the extent applicable, the historical earnings and cash flows associated with the assets acquired or disposed
of, any related 

  
 55 

 
repayment, redemption, incurrence or reduction of Indebtedness (each such calculation, calculated on a “Pro Forma Basis”). If any Indebtedness bears a floating rate of interest
and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the date of determination had been the applicable rate for the entire period (taking into account any Swap Agreement
applicable to such Indebtedness). 
 (d) Foreign Currency Calculations. (i) For purposes of determining compliance with
any Dollar-denominated restriction on the incurrence of Indebtedness, the Dollar equivalent of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness
was incurred, in the case of term debt, or first committed, in the case of revolving credit debt; provided that if such Indebtedness is incurred to extend, replace, refund, refinance, renew or defease other Indebtedness denominated in a
foreign currency, and such extension, replacement, refunding, refinancing, renewal or defeasance would cause the applicable Dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of
such extension, replacement, refunding, refinancing, renewal or defeasance, such Dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal
amount of such Indebtedness being extended, replaced, refunded, refinanced, renewed or defeased. The principal amount of any Indebtedness incurred to extend, replace, refund, refinance, renew or defease other Indebtedness, if incurred in a different
currency from the Indebtedness being extended, replaced, refunded, refinanced, renewed or defeased, shall be calculated based on the currency exchange rate applicable to the currencies in which such respective Indebtedness is denominated that is in
effect on the date of such extension, replacement, refunding, refinancing, renewal or defeasance. 
 (ii) Wherever in this Credit Agreement
in connection with a Revolving Borrowing or conversion, continuation or prepayment of a Eurodollar Loan, an amount, such as a required minimum or multiple amount, is expressed in Dollars, but such Revolving Borrowing or Eurodollar Loan is
denominated in an Alternative Currency, such amount shall be the relevant Alternative Currency Equivalent of such Dollar amount (rounded to the nearest unit of such Alternative Currency, with 0.5 of a unit being rounded upward), as determined
by the Administrative Agent. The Administrative Agent shall determine the Spot Rates as of each Revaluation Date to be used for calculating Dollar Equivalent amounts of Revolving Outstandings and Outstanding Amounts denominated in Alternative
Currencies. Such Spot Rates shall become effective as of such Revaluation Date and shall be the Spot Rates employed in converting any amounts between the applicable currencies until the next Revaluation Date to occur. 

Section 1.04 Rounding. Any financial ratios required to be maintained by MKS or any of its Restricted
Subsidiaries pursuant to this Agreement shall be calculated by dividing the appropriate component by the other component, carrying the result to one place more than the number of places by which such ratio is expressed herein and rounding the result
up or down to the nearest number (with a rounding-up if there is no nearest number). 

Section 1.05 Times of Day. Unless otherwise specified, all references herein to times of day shall be
references to Eastern time (daylight or standard, as applicable). 
 Section 1.06 Letter of Credit
Amounts. Unless otherwise specified herein, the amount of a Letter of Credit at any time shall be deemed to be the stated amount of such Letter of Credit in effect at such time; provided, however, that with respect to any
Letter of Credit that, by its terms or the terms of any L/C Document related thereto, provides for one or more automatic increases in the stated amount thereof, the amount of such Letter of Credit shall be deemed to be the maximum stated amount of
such Letter of Credit after giving effect to all such increases, whether or not such maximum stated amount is in effect at such time. 

  
 56 

 Section 1.07 Types of Borrowings. Identification of
a Borrowing by Type (e.g., a “Eurodollar Borrowing”) indicates that such Borrowing is comprised of Loans of such Type. 

Section 1.08 Additional Alternative Currencies. 

(a) MKS may from time to time request that Eurodollar Loans be made and/or Letters of Credit be issued in a currency not specifically listed in
the definition of “Alternative Currency;” provided that such requested currency is a lawful currency (other than Dollars) that is readily available and freely transferable and convertible into Dollars. In the case of any such
request with respect to the making of Eurodollar Loans, such request shall be subject to the approval of the Administrative Agent and the Lenders; and in the case of any such request with respect to the issuance of Letters of Credit, such request
shall be subject to the approval of the Administrative Agent and the applicable L/C Issuer. 
 (b) Any such request shall be made to the
Administrative Agent not later than 11:00 a.m., twenty Business Days’ prior to the date of the desired Credit Extension (or such other time or date as may be agreed by the Administrative Agent and, in the case of any such request
pertaining to Letters of Credit, the applicable L/C Issuer, in its or their sole discretion). In the case of any such request pertaining to Eurodollar Loans, the Administrative Agent shall promptly notify each Revolving Lender thereof; and in the
case of any such request pertaining to Letters of Credit, the Administrative Agent shall promptly notify the applicable L/C Issuer thereof. Each Lender (in the case of any such request pertaining to Eurodollar Loans) or the applicable L/C Issuer (in
the case of a request pertaining to Letters of Credit) shall notify the Administrative Agent, not later than 11:00 a.m., ten Business Days after receipt of such request whether it consents, in its sole discretion, to the making of Eurodollar
Loans or the issuance of Letters of Credit, as the case may be, in such requested currency. 
 (c) Any failure by a Lender or the applicable
L/C Issuer, as the case may be, to respond to such request within the time period specified in the preceding sentence shall be deemed to be a refusal by such Lender or the applicable L/C Issuer, as the case may be, to permit Eurodollar Loans to be
made or Letters of Credit to be issued in such requested currency. If the Administrative Agent and all the Lenders consent to making Eurodollar Loans in such requested currency, the Administrative Agent shall so notify MKS and such currency shall
thereupon be deemed for all purposes to be an Alternative Currency hereunder for purposes of any Revolving Borrowings of Eurodollar Loans; and if the Administrative Agent and the applicable L/C Issuer consent to the issuance of Letters of Credit in
such requested currency, the Administrative Agent shall so notify MKS and such currency shall thereupon be deemed for all purposes to be an Alternative Currency hereunder for purposes of any Letter of Credit issuances. If the Administrative Agent
shall fail to obtain consent to any request for an additional currency under this Section 1.08, the Administrative Agent shall promptly so notify MKS. 

Section 1.09 Change of Currency. 

(a) Each obligation of the Borrowers to make a payment denominated in the national currency unit of any member state of the European Union that
adopts the Euro as its lawful currency after the date hereof shall be redenominated into Euro at the time of such adoption (in accordance with the EMU Legislation). If, in relation to the currency of any such member state, the basis of accrual of
interest expressed in this Agreement in respect of that currency shall be inconsistent with any convention or practice in the London interbank market for the basis of accrual of interest in respect of the Euro, such expressed basis shall be replaced
by such convention or practice with effect from the date on which such member state adopts the Euro as its lawful currency; provided that if any Revolving Borrowing in the currency of such member state is outstanding immediately prior to such
date, such replacement shall take effect, with respect to such Revolving Borrowing, at the end of the then current Interest Period. 

  
 57 

 (b) Each provision of this Agreement shall be subject to such reasonable changes of
construction as the Administrative Agent may from time to time specify to be appropriate to reflect the adoption of the Euro by any member state of the European Union and any relevant market conventions or practices relating to the Euro. 

(c) Each provision of this Agreement also shall be subject to such reasonable changes of construction as the Administrative Agent may from time
to time specify to be appropriate to reflect a change in currency of any other country and any relevant market conventions or practices relating to the change in currency. 

Section 1.10 Joint and Several Obligations. 

(a) Each of the Borrowers acknowledges and agrees that (i) it is a co-borrower hereunder and shall
be jointly and severally, with the other Borrowers, directly and primarily liable for the Finance Obligations regardless of which Borrower actually receives Loans or other extensions of credit hereunder or the amount of such Loans or other
extensions of credit received or the manner in which the Administrative Agent and/or any Lender or L/C Issuer accounts for such Loans or other extensions of credit on its books and records, (ii) each of the Borrowers shall have the obligations
of co-maker and shall be primary obligors with respect to all Loans, the Letters of Credit and the other Finance Obligations, it being agreed that such extensions of credit to each Borrower inure to the
benefit of all Borrowers, and (iii) the Administrative Agent and each of the Lenders and L/C Issuers is relying on such joint and several liability of the Borrowers as co-makers in extending the Loans and
issuing the Letters of Credit hereunder. Each Borrower’s obligations with respect to Loans made to it or with respect to any Letters of Credit issued for its account, and each Borrower’s obligations arising as a result of the joint and
several liability of the Borrowers hereunder, with respect to Loans made to the other Borrower hereunder or with respect to any Letters of Credit issued for the account of any other Borrower hereunder, shall be separate and distinct obligations, but
all such Finance Obligations shall be primary obligations of each Borrower. Each Borrower hereby unconditionally and irrevocably agrees that upon default in the payment when due (whether at stated maturity, by acceleration or otherwise) of any
principal of, or interest on, any Finance Obligation payable by it to the Lender, it will forthwith pay the same, without notice of demand. 

(b) Each Borrower’s obligations arising as a result of the joint and several liability of the Borrowers hereunder with respect to the
Finance Obligations of the other Borrowers hereunder shall, to the fullest extent permitted by law, be unconditional irrespective of (i) the validity or enforceability, avoidance or subordination of the Finance Obligations of the other
Borrowers or other document evidencing all or any part of the Finance Obligations of the other Borrowers, (ii) the absence of any attempt to collect the Finance Obligations from any other Borrower, or any other security therefor, or the absence
of any other action to enforce the same, (iii) the waiver, consent, extension, forbearance or granting of any indulgence by any Agent or any Lender or L/C Issuer with respect to any provision of any instrument evidencing the Finance Obligations
of any other Borrower, or any part thereof, or any other agreement now or hereafter executed by any other Borrower and delivered to any Agent or any Lender or L/C Issuer, (iv) the failure by any Agent or any Lender or L/C Issuer to take any
steps to perfect and maintain its security interest in, or to preserve its rights to, any security for the Finance Obligations of any other Borrower, (v) any borrowing or grant of a security interest by any other Borrower, as debtors-in-possession under Section 364 of the Bankruptcy Code, (vi) the disallowance of all or any portion of any Agent’s or any Lender’s or L/C
Issuer’s claim(s) for the repayment of the Finance Obligations of any other Borrower under Section 502 of the Bankruptcy Code, or (vii) any other circumstances which might constitute a legal or equitable discharge or defense of any
other Borrower. 

  
 58 

 (c) With respect to each Borrower’s obligations arising as a result of the joint and
several liability of the Borrowers hereunder with respect to the Finance Obligations of any of the other Borrowers hereunder, each Borrower waives, until the Revolving Termination Date, any right to enforce any right of subrogation or any remedy
which any Agent or any Lender now has or may hereafter have against such Borrower, any endorser or any guarantor of all or any part of the Finance Obligations, and any benefit of, and any right to participate in, any security or collateral given to
any Agent or any Lender to secure payment of the Finance Obligations. 
 (d) No payment or payments made by any of the Borrowers or any other
Person or received or collected by any Agent or any Lender or L/C Issuer from any of the Borrowers or any other Person by virtue of any action or proceeding or any set-off or appropriation or application at
any time or from time to time in reduction of or in payment of the Finance Obligations shall be deemed (except to the extent Finance Obligations are satisfied) to modify, release or otherwise affect the liability of any Borrower under this
Agreement, which shall remain liable for the Finance Obligations until the Revolving Termination Date. 

Section 1.11 Designated Borrower. 

Each Borrower may at any time, and from time to time, after the Closing Date by delivery to the Administrative Agent of a Borrower Designation
Agreement duly executed by such Borrower and a specified Wholly-Owned Domestic Subsidiary (who shall be a Restricted Subsidiary), in substantially the form of Exhibit L hereto or such other form as agreed to by the

aforementioned executed Borrower Designation Agreement, (ii) up-to-date certificates and Organization Documents in respect of such Subsidiary, similar to those
delivered pursuant to Section 4.01(b), (iii) all amendments or joinders to this Agreement, any Revolving Notes issued and any other Loan Document deemed reasonably necessary by the Administrative Agent to accommodate

different Person, then it shall be deemed to have been transferred from the original Person to the subsequent Person, and (b) if any new Person comes into existence, such new Person shall be deemed to have been organized on the first date of

received to the L/C Issuer which has issued Letters of Credit having outstanding Unreimbursed Amounts as contemplated by Section 2.05(e)(v). 

(c) Funding by the Administrative Agent in Anticipation of Amounts Due from the Lenders. Unless the Administrative Agent shall
have received notice from a Lender prior to the proposed date of any Revolving Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Revolving Borrowing, the Administrative Agent may assume
that such Lender has made such share available to the Administrative Agent on the date of such Revolving Borrowing in accordance with clause (b) above, and the Administrative Agent may, in reliance upon such

  
 61 

 
assumption, but is not required to, make available to each applicable Borrower on such date a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable
Revolving Borrowing available to the Administrative Agent then the applicable Lender and the Borrowers severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount in immediately available funds with interest
thereon, for each day from and including the date such amount is made available to any Borrower but excluding the date of payment to the Administrative Agent at (i) in the case of a payment to be made by such Lender, the greater of the
Overnight Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation and (ii) in the case of a payment to be made by a Borrower, the interest rate applicable thereto pursuant to
Section 2.06. If a Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to such Borrower the amount of such
interest paid by such Borrower for such period. If such Lender pays its share of the applicable Revolving Borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in such Revolving Borrowing.
Any payment by any Borrower shall be without prejudice to any claim such Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent. A notice of the Administrative Agent to a Lender or Borrower with
respect to any amount owing under this clause (c) shall be conclusive, absent manifest error. 
 (d) Failed
Loans. If any Lender shall fail to make any Loan (a “Failed Loan”) which such Lender is otherwise obligated hereunder to make to a Borrower on the date of Revolving Borrowing thereof, and the Administrative Agent shall not
have received notice from such Borrower or such Lender that any condition precedent to the making of the Failed Loan has not been satisfied, then, until such Lender shall have made or be deemed to have made (pursuant to the last sentence of this
clause (d)) the Failed Loan in full or the Administrative Agent shall have received notice from such Borrower or such Lender that any condition precedent to the making of the Failed Loan was not satisfied at the time the
Failed Loan was to have been made, whenever the Administrative Agent shall receive any amount from a Borrower for the account of such Lender, (i) the amount so received (up to the amount of such Failed Loan) will, upon receipt by the
Administrative Agent, be deemed to have been paid to the Lender in satisfaction of the obligation for which paid, without actual disbursement of such amount to the Lender, (ii) the Lender will be deemed to have made the same amount available to
the Administrative Agent for disbursement as a Loan to such Borrower (up to the amount of such Failed Loan) and (iii) the Administrative Agent will disburse such amount (up to the amount of the Failed Loan) to such Borrower or, if the
Administrative Agent has previously made such amount available to such Borrower on behalf of such Lender pursuant to the provisions hereof, reimburse itself (up to the amount of the amount made available to such Borrower); provided,
however, that the Administrative Agent shall have no obligation to disburse any such amount to any Borrower, or otherwise apply it or deem it applied as provided herein unless the Administrative Agent shall have determined in its sole
discretion that to so disburse such amount will not violate any Law, rule, regulation or requirement applicable to the Administrative Agent. Upon any such disbursement by the Administrative Agent, such Lender shall be deemed to have made a Base Rate
Loan to the applicable Borrower in satisfaction, as applicable, to the extent thereof, of such Lender’s obligation to make the Failed Loan. 

Section 2.04 Evidence of Loans. 

(a) Lender and Administrative Agent Accounts; Revolving Notes. The Credit Extensions made by each Lender shall be evidenced by
one or more accounts or records maintained by such Lender and by the Administrative Agent in the ordinary course of business. The accounts or records maintained by the Administrative Agent and each Lender shall be conclusive absent manifest error of
the amount of the Credit Extensions made by the Lenders to the Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the

  
 62 

 
obligation of any Borrower hereunder to pay any amount owing with respect to the Senior Credit Obligations. In the event of any conflict between the accounts and records maintained by any Lender
and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender made through the Administrative
Agent, the Borrowers shall execute and deliver to such Lender (through the Administrative Agent) a single Revolving Note, as applicable, in each case, substantially in the form of Exhibit B, payable to the order of such
Lender for the account of its Lending Office in an amount equal to the aggregate unpaid principal amount of such Lender’s Revolving Loans, which shall evidence such Lender’s Loans in addition to such accounts or records. Each Lender having
one or more Revolving Notes shall record the date, amount and Type of each Loan made by it and the date and amount of each payment of principal made by a Borrower with respect thereto, and may, if such Lender so elects in connection with any
transfer or enforcement of any Revolving Note, endorse on the reverse side or on the schedule, if any, forming a part thereof appropriate notations to evidence the foregoing information with respect to each outstanding Loan evidenced thereby;
provided that the failure of any Lender to make any such recordation or endorsement or any error in any such recordation or endorsement shall not affect the obligations of any Borrower hereunder or under any such Revolving Note. Each Lender
is hereby irrevocably authorized by each Borrower so to endorse each of its Revolving Notes and to attach to and make a part of each of its Revolving Notes a continuation of any such schedule as and when required. In the event of any conflict
between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. 

(b) Certain Participation Interests. In addition to the accounts and records referred to in clause (a)
above, each Lender and the Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing purchases and sales by such Lender of Participation Interests in Letters of Credit. In the event of any conflict
between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. 

Section 2.05 Letters of Credit. 

(a) Letters of Credit. Subject to the terms and conditions set forth herein, (i) each L/C Issuer agrees, in reliance upon
the agreements of the other Lenders set forth in this Section 2.05, (A) from time to time on any Business Day during the period after the Closing Date until the Letter of Credit Expiration Date, to issue standby
Letters of Credit (which shall denominated in Dollars) for the account, and upon the request, of any Borrower (or jointly for the account of any Borrower and any of its Subsidiaries), and to amend or extend Letters of Credit previously issued by it,
in accordance with clause (c) below and (B) to honor drawings under its Letters of Credit, and (ii) each Lender severally agrees to participate in Letters of Credit issued for the account of any Borrower or any of
its Subsidiaries and any drawing thereunder in accordance with the provisions of clause (e) below; provided that, immediately after each Letter of Credit is issued, (i) the aggregate amount of the L/C
Obligations shall not exceed the L/C Sublimit, (ii) the Revolving Outstandings shall not exceed the Line Cap and (iii) with respect to each individual Lender, the aggregate outstanding principal amount of such Lender’s Revolving Loans
plus its participation interests in Protective Advance Exposure plus its Participation Interests in outstanding L/C Obligations shall not exceed such Lender’s Revolving Commitment. Each request by a Borrower or any of its
Subsidiaries for the issuance or increase in the stated amount of a Letter of Credit shall be deemed to be a representation by the Borrowers that the issuance or increase in the stated amount of such Letter of Credit complies with the conditions set
forth in the proviso to the preceding sentence. Within the foregoing limits, and subject to the terms and conditions hereof, the Borrowers’ ability to obtain Letters of Credit shall be fully revolving, and accordingly the Borrowers may, during
the period specified in clause (i)(A) above, obtain Letters of Credit to replace Letters of Credit that have expired or that have been drawn upon and reimbursed. 

  
 63 

 (b) Certain Limitations on Issuances of Letters of Credit. (i) No L/C
Issuer shall issue any Letter of Credit, if (A) subject to clause (c) below with respect to Auto-Extension Letters of Credit, the expiry date of such requested Letter of Credit would occur more than twelve months after
the date of issuance or last extension, unless the Administrative Agent and the applicable L/C Issuer have approved such expiry date, or (B) the expiry date of such requested Letter of Credit would occur after the Letter of Credit Expiration
Date. 
 (ii) No L/C Issuer shall be under any obligation to issue any Letter of Credit if: (A) any order, judgment or decree of any
Governmental Authority shall by its terms purport to enjoin or restrain such L/C Issuer from issuing such Letter of Credit, or any Law applicable to such L/C Issuer or any request or directive (whether or not having a force of Law) from any
Governmental Authority with jurisdiction over such L/C Issuer shall prohibit, or request that such L/C Issuer refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon such L/C Issuer with
respect to such Letter of Credit any restriction, reserve or capital or liquidity requirement (for which such L/C Issuer is not otherwise compensated hereunder) not in effect on the Closing Date, or shall impose upon such L/C Issuer any unreimbursed
loss, cost or expense which was not applicable on the Closing Date and which such L/C Issuer in good faith deems material to it; (B) the issuance of such Letter of Credit shall violate any Laws or one or more policies of such L/C Issuer;
(C) except as otherwise agreed by the Administrative Agent and such L/C Issuer, such Letter of Credit is in an initial stated amount less than $100,000; or (D) a default of any Revolving Lender’s obligations to fund under
clause (e)(iv) or (vi) below exists or any Revolving Lender is at such time a Defaulting Lender hereunder, unless such L/C Issuer has entered into arrangements, including the delivery of Cash Collateral,
satisfactory to such L/C Issuer (in its sole discretion) with the Borrowers or such Revolving Lender to eliminate such L/C Issuer’s actual or potential Fronting Exposure (after giving effect to Section 2.17(a)(iv))
with respect to the Defaulting Lender arising from either the Letter of Credit then proposed to be issued or that Letter of Credit and all other L/C Obligations as to which such L/C Issuer has actual or potential Fronting Exposure, as it may elect
in its sole discretion. 
 (iii) No L/C Issuer shall amend any Letter of Credit if such L/C Issuer would not be permitted at such time to
issue such Letter of Credit in its amended form under the terms hereof. 
 (iv) No L/C Issuer shall be under any obligation to amend any
Letter of Credit if (A) such L/C Issuer would have no obligation at such time to issue such Letter of Credit in its amended form under the terms hereof, or (B) the beneficiary of such Letter of Credit does not accept the proposed amendment
to such Letter of Credit. 
 (v) Each L/C Issuer shall act on behalf of the Revolving Lenders with respect to any Letters of Credit issued by
it and the documents associated therewith, and each L/C Issuer shall have all of the benefits and immunities (A) provided to the Administrative Agent in Article IX with respect to any acts taken or omissions suffered
by such L/C Issuer in connection with Letters of Credit issued by it or proposed to be issued by it and the L/C Documents pertaining to such Letters of Credit as fully as if the term “Administrative Agent” as used in
Article IX included such L/C Issuer with respect to such acts or omissions and (B) as additionally provided herein with respect to such L/C Issuer. 

(c) Procedures for Issuance and Increases in the Amounts of Letters of Credit. (i) Each Letter of Credit shall be issued or
amended, as the case may be, upon the request of a Borrower delivered to the applicable L/C Issuer (with a copy to the Administrative Agent) substantially in the form of Exhibit A-2
hereto (a “Letter of Credit Request”), appropriately completed and signed by a 

  
 64 

 
Responsible Officer of such Borrower including agreed-upon draft language for such Letter of Credit reasonably acceptable to the applicable L/C Issuer. Such Letter of Credit Request must be
received by the applicable L/C Issuer and the Administrative Agent not later than 2:00 p.m. at least five Business Days (or such later date and time as such L/C Issuer may agree in a particular instance in its sole discretion) prior to the
proposed issuance date or date of increase, as the case may be. In the case of a request for an initial issuance of a Letter of Credit, such Letter of Credit Request shall specify in form and detail reasonably satisfactory to such L/C Issuer:
(A) the proposed issuance date of the requested Letter of Credit (which shall be a Business Day); (B) the amount thereof; (C) the expiry date thereof, (D) the name and address of the beneficiary thereof; (E) the documents to
be presented by such beneficiary in case of any drawing thereunder; (F) the full text of any certificate to be presented by such beneficiary in case of any drawing thereunder; and (G) such other matters as such L/C Issuer may reasonably
require. In the case of a request for an increase in the stated amount of any outstanding Letter of Credit, such Letter of Credit Request shall specify in form and detail satisfactory to such L/C Issuer: (A) the Letter of Credit to be amended;
(B) the proposed date of amendment thereof (which shall be a Business Day); (C) the amount of the proposed increase; and (D) such other matters as such L/C Issuer may reasonably require. If requested by the applicable L/C Issuer, the
Borrower shall also submit a Letter of Credit Application on such L/C Issuer’s standard form in connection with any request for the issuance or increase in the stated amount of a Letter of Credit. Additionally, the Borrower shall furnish to
such L/C Issuer and the Administrative Agent such other documents and information pertaining to such requested Letter of Credit issuance or amendment, including any L/C Documents, as such L/C Issuer or the Administrative Agent may reasonably
require. 
 (ii) Promptly after receipt of any Letter of Credit Request, the applicable L/C Issuer will confirm with the Administrative
Agent (by telephone or in writing) that the Administrative Agent has received a copy of such Letter of Credit Request from a Borrower and, if not, such L/C Issuer will provide the Administrative Agent with a copy thereof. Unless such L/C Issuer has
received written notice from any Revolving Lender, the Administrative Agent or any Loan Party, at least one Business Day prior to the requested date of issuance or amendment of the applicable Letter of Credit, that one or more applicable conditions
contained in Article IV shall not then be satisfied, then, subject to the terms and conditions thereof, such L/C Issuer shall, on the requested date, issue a Letter of Credit for the account of such Borrower (or jointly for
the account of such Borrower or the applicable Subsidiary) or enter into the applicable amendment, as the case may be, in each case in accordance with such L/C Issuer’s usual and customary business practices. 

(iii) If a Borrower so requests in any applicable Letter of Credit Request, the applicable L/C Issuer may, in its sole and absolute
discretion, agree to issue a Letter of Credit that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”); provided that any such Auto-Extension Letter of Credit must permit such L/C Issuer to prevent
any such extension at least once in each twelve-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the
“Non-Extension Notice Date”) in each such twelve-month period to be agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by such L/C Issuer, such Borrower shall
not be required to make a specific request to such L/C Issuer for any such extension. Once an Auto-Extension Letter of Credit has been issued, the Revolving Lenders shall be deemed to have authorized (but may not require) such L/C Issuer to permit
the extension of such Letter of Credit at any time to a date not later than the Letter of Credit Expiration Date; provided, however, that such L/C Issuer shall not permit any such extension if (A) such L/C Issuer has determined
that it would not be permitted, or would have no obligation, at such time to issue such Letter of Credit in its revised form (as extended) under the terms hereof (by reason of the provisions of clause (c)(i) or
(ii) above or otherwise) or (B) it has received notice (which may be by telephone or in writing) on or before the day that is five Business Days before the Non-Extension Notice Date from the
Administrative Agent or any Loan Party that one or more of the applicable conditions specified in Section 4.02 are not 

  
 65 

 
then satisfied (for the avoidance of doubt, the provision of any such notice to such L/C Issuer pursuant to this clause (y) shall not relieve any Revolving Lender of its
obligation to fund its share of any such Letter of Credit that is not extended, to the extent such Letter of Credit is drawn under the terms of this Agreement), and in each such case directing such L/C Issuer not to permit such extension. 

(iv) Promptly after its delivery of any Letter of Credit or any amendment to a Letter of Credit to an advising bank with respect thereto or to
the beneficiary thereof, the applicable L/C Issuer will also deliver to the applicable Borrower and the Administrative Agent a true and complete copy of such Letter of Credit or amendment. 

(d) Purchase and Sale of Letter of Credit Participation. Immediately upon the issuance by an L/C Issuer of a Letter of Credit,
such L/C Issuer shall be deemed, without further action by any party hereto, to have sold to each Revolving Lender, and each Revolving Lender shall be deemed, without further action by any party hereto, to have purchased from such L/C Issuer,
without recourse or warranty, an undivided Participation Interest in such Letter of Credit and the related L/C Obligations in the proportion its Revolving Commitment Percentage bears to the Revolving Committed Amount (although any fronting fee
payable under Section 2.11 shall be payable directly to the Administrative Agent for the account of the applicable L/C Issuer, and the Lenders (other than such L/C Issuer) shall have no right to receive any portion of any
such fronting fee) and any security therefor or guaranty pertaining thereto. Upon any change in the Revolving Commitments pursuant to Section 10.06, there shall be an automatic adjustment to the Participation Interests in
all outstanding Letters of Credit and all L/C Obligations to reflect the adjusted Revolving Commitments of the assigning and assignee Lenders or of all Lenders having Revolving Commitments, as the case may be. 

(e) Drawings and Reimbursements; Funding of Participations. (i) Upon receipt from the beneficiary of any Letter of Credit of
any notice of a drawing under such Letter of Credit, the applicable L/C Issuer shall promptly notify the Borrowers and the Administrative Agent thereof and shall determine in accordance with the terms of such Letter of Credit whether such drawing
should be honored. If the applicable L/C Issuer determines that any such drawing shall be honored, such L/C Issuer shall make available to such beneficiary in accordance with the terms of such Letter of Credit the amount of the drawing and shall
notify the Borrowers and the Administrative Agent as to the amount to be paid as a result of such drawing and the payment date (which date shall be one Business Day after the date of the drawing) (each such date, an “Honor Date”).

 (ii) The Borrowers shall be irrevocably and unconditionally obligated forthwith, upon any drawing under any Letter of Credit, to
reimburse each L/C Issuer or each L/C Issuer through the Administrative Agent for any amounts paid by such L/C Issuer together with any and all reasonable charges and expenses which such L/C Issuer may pay or incur relative to such drawing. Such
reimbursement payment shall be due and payable on the same day as the Honor Date if notice is received prior to 11:00 a.m., or the next Business Day after the Honor Date otherwise. In addition, the Borrowers agree to pay to such L/C Issuer
interest, payable on demand, on any and all amounts not paid by the Borrowers to such L/C Issuer when due under this clause (e)(ii), for each day from and including the date when such amount becomes due to but excluding the
date such amount is paid in full, whether before or after judgment, at a rate per annum equal to the Default Rate. Each reimbursement and other payment to be made by the Borrowers pursuant to this clause (ii) shall
be made to such L/C Issuer in Federal or other funds immediately available to it at its address referred to in Section 10.02. 

(iii) Subject to the satisfaction of all applicable conditions set forth in Article IV, the Borrowers may, at their
option, utilize the Revolving Commitments, or make other arrangements for payment satisfactory to the applicable L/C Issuer, for the reimbursement of all L/C Disbursements as required by clause (ii) above. 

  
 66 

 (iv) With respect to any L/C Disbursements that have not been reimbursed by the Borrowers
when due under clauses (ii) and (iii) above (an “Unreimbursed Amount”), the Administrative Agent shall promptly notify each Revolving Lender of the Honor Date, the amount of the Unreimbursed
Amount and the amount of such Revolving Lender’s pro rata share thereof and such Revolving Lender’s pro rata share of such unreimbursed L/C Disbursement (determined by the proportion its Revolving Commitment Percentage bears to the
aggregate Revolving Committed Amount). In such event, the Borrowers shall be deemed to have requested an “L/C Borrowing” of Base Rate Loans to be disbursed on the next Business Day following the Honor Date in an aggregate amount in
Dollars equal to the Unreimbursed Amount, without regard to the minimum and multiples specified in Section 2.01(a), but subject to (A) the conditions that after making such L/C Borrowing, the Revolving Outstandings do
not exceed the Line Cap and (B) the conditions set forth in Section 4.02 (other than the delivery of a Notice of Borrowing), and each such Lender hereby agrees to make a Loan (which shall be initially funded as a Base
Rate Loan) in an amount equal to such Lender’s Revolving Commitment Percentage of the Unreimbursed Amount outstanding on the date notice is given. Any such notice given by the Administrative Agent given pursuant to this
clause (iv) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice. 

(v) Each Lender (including any Lender acting as a L/C Issuer in respect of any Unreimbursed Amount) shall, upon any notice from the
Administrative Agent pursuant to clause (iv) above, make the amount of its Loan available to the Administrative Agent in Federal or other immediately available funds, at the Administrative Agent’s Office, not later
than 1:00 p.m. on the Business Day specified in such notice, whereupon, subject to clause (vi) below, each Lender that so makes funds available shall be deemed to have made a Loan (which shall be a Base Rate Loan) to
the Borrowers in such amount. The Administrative Agent shall remit the funds so received (and the Administrative Agent may apply Cash Collateral provided for this purpose) to the applicable L/C Issuer. 

(vi) With respect to any Unreimbursed Amount that is not fully refinanced by an L/C Borrowing pursuant to
clauses (iv) and (v) above because the conditions set forth in Section 4.02 cannot be satisfied or for any other reason, the Administrative Agent shall promptly notify each Revolving
Lender (other than the relevant L/C Issuer), and each such Revolving Lender shall promptly and unconditionally pay to the Administrative Agent, for the account of such L/C Issuer, such Revolving Lender’s pro rata share of such Unreimbursed
Amount (determined by the proportion its Revolving Commitment Percentage bears to the aggregate Revolving Committed Amount) in Dollars in Federal or other immediately available funds. Such payment from the Revolving Lenders shall be due (i) at
or before 1:00 p.m. on the date the Administrative Agent so notifies a Revolving Lender, if such notice is given at or before 10:00 a.m. on such date or (ii) at or before 10:00 a.m. on the next succeeding Business Day, together
with interest on such amount for each day from and including the date of such drawing to but excluding the day such payment is due from such Revolving Lender at the Federal Funds Rate for such day (which funds the Administrative Agent shall promptly
remit to the applicable L/C Issuer). Each payment by a Revolving Lender to the Administrative Agent for the account of an L/C Issuer in respect of an Unreimbursed Amount shall constitute a payment in respect of its Participation Interest in the
related Letter of Credit purchased pursuant to clause (d) above. The failure of any Revolving Lender to make available to the Administrative Agent for the account of an L/C Issuer its pro rata share of any Unreimbursed
Amount shall not relieve any other Revolving Lender of its obligation hereunder to make available to the Administrative Agent for the account of such L/C Issuer its pro rata share of any payment made under any Letter of Credit on the date required,
as specified above, but no such Lender shall be responsible for the failure of any other Lender to make available to the Administrative Agent for the account of such L/C Issuer such other Lender’s pro rata share of any such payment. Upon
payment in full of all amounts payable by a Lender under this clause (vi), such Lender shall be subrogated to the rights of such L/C Issuer against the Borrowers to the extent of such Lender’s pro rata share of the
related L/C Obligation so paid (including interest accrued thereon). 

  
 67 

 (vii) Each Revolving Lender’s obligation to make Revolving Loans pursuant to
clause (iv) above and to make payments in respect of its Participation Interests in Unreimbursed Amounts pursuant to clause (vi) above shall be absolute and unconditional and shall not be affected
by any circumstance, including: (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the applicable L/C Issuer, any Borrower or any other Person for any reason whatsoever; (B) the occurrence
or continuance of a Default; or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Revolving Lender’s obligation to make Revolving Loans as a part of an
L/C Borrowing pursuant to clause (iv) above is subject to the conditions set forth in Section 4.02 (other than delivery by a Borrower of a Notice of Borrowing). No such making by a Revolving Lender
of a Revolving Loan or a payment by a Revolving Lender of an amount in respect of its Participation Interest in Unreimbursed Amounts shall relieve or otherwise impair the obligation of any Borrower to reimburse such L/C Issuer for the amount of any
payment made by such L/C Issuer under any Letter of Credit, together with interest as provided herein. 
 (viii) If any Revolving Lender
fails to make available to the Administrative Agent for the account of an L/C Issuer any amount required to be paid by such Revolving Lender pursuant to the foregoing provisions of this clause (e) by the time specified
therefor, then, without limiting the other provisions of this Agreement, the applicable L/C Issuer shall be entitled to recover from such Revolving Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for
the period from the date such payment is required to the date on which such payment is immediately available to the applicable L/C Issuer at a rate per annum equal to the Federal Funds Rate for such day. Any payment made by any Lender
after 3:00 p.m. on any Business Day shall be deemed for purposes of the preceding sentence to have been made on the next succeeding Business Day. A certificate of the applicable L/C Issuer submitted to any Revolving Lender (through the
Administrative Agent) with respect to any amounts owing under this clause (viii) shall be conclusive absent manifest error. 

(f) Repayment of Funded Participations in Respect of Drawn Letters of Credit. (i) Whenever the Administrative Agent
receives a payment of an L/C Obligation as to which the Administrative Agent has received for the account of an L/C Issuer any payments from the Revolving Lenders pursuant to clause (e) above (whether directly from a
Borrower or otherwise, including proceeds of cash collateral applied thereto by the Administrative Agent), the Administrative Agent shall promptly pay to each Revolving Lender which has paid its pro rata share thereof an amount equal to such
Lender’s pro rata share of the amount thereof (appropriately adjusted, in the case of interest payments, to reflect the period of time during which the payments from the Revolving Lenders were received) in the same funds as those received by
the Administrative Agent. 
 (ii) If any payment received by the Administrative Agent for the account of an L/C Issuer pursuant to
clause (i) above is required to be returned under any of the circumstances described in Section 10.05 (including pursuant to any settlement entered into by such L/C Issuer in its discretion), each
Revolving Lender shall pay to the Administrative Agent for the account of such L/C Issuer its pro rata share thereof (determined by the proportion its Revolving Commitment Percentage bears to the aggregate Revolving Committed Amount) on demand of
the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Revolving Lender, at a rate per annum equal to the Federal Funds Rate for such day. 

  
 68 

 (g) Obligations Absolute. The obligations of each Borrower under
Sections 2.05(e)(i) and 2.05(e)(ii) above shall be absolute (subject to the right to bring claims subject to the limitations set forth in Section 2.05(l)(v)) and unconditional and shall
be performed strictly in accordance with the terms of this Agreement, ISP and Uniform Customs and Practice for Documentary Credits, as applicable, under all circumstances whatsoever, including, without limitation, the following circumstances:

 (i) any lack of validity or enforceability of such Letter of Credit, this Agreement or any other Loan Document; 

(ii) the use which may be made of the Letter of Credit by, or any acts or omission of, a beneficiary of a Letter of Credit (or any Person for
whom the beneficiary may be acting); 
 (iii) the existence of any claim, counterclaim, setoff, defense or other rights that any Borrower or
any Subsidiary may have at any time against a beneficiary or any transferee of a Letter of Credit (or any Person for whom the beneficiary or transferee may be acting), any L/C Issuer or any other Person, whether in connection with this Agreement or
any Letter of Credit or any document related hereto or thereto or any unrelated transaction; 
 (iv) any draft, demand, certificate,
statement or any other document presented under a Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect whatsoever, or any loss or delay in the
transmission or otherwise of any document required in order to make a drawing under such Letter of Credit; 
 (v) any payment by any L/C
Issuer under a Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; 

(vi) any payment made by any L/C Issuer under such Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, examiner, receiver or other representative of or successor to any beneficiary or any transferee of
such Letter of Credit, including any arising in connection with any proceeding under any Insolvency or Liquidation Proceeding; or 
 (vii)
any other act or omission to act or delay of any kind by any L/C Issuer or any other Person or any other event or circumstance whatsoever that might, but for the provisions of this clause (ix), constitute a legal or
equitable discharge of any Borrower’s obligations hereunder; 
 provided that the foregoing shall not excuse any L/C Issuer from liability to
the Borrowers to the extent of any direct damages (as opposed to punitive or consequential damages or lost profits, claims in respect of which are waived by a Borrower to the extent permitted by applicable Law) suffered by the Borrowers that are
caused by acts or omissions by such L/C Issuer constituting gross negligence or willful misconduct on the part of such L/C Issuer (as determined by a court of competent jurisdiction in a final non-appealable
judgment). 
 Each Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto that is delivered to it and,
in the event of any claim of noncompliance with any Borrower’s instructions or other irregularity, each Borrower will promptly notify the applicable L/C Issuer. Each Borrower shall be conclusively deemed to have waived any such claim against
such L/C Issuer and its correspondents unless such notice is given as aforesaid. 

  
 69 

 (h) Role of L/C Issuers; Reliance. Each Revolving Lender and each Borrower
agree that the relevant L/C Issuer shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy
of any such document or the authority of the Person executing or delivering any such document. None of the L/C Issuers, the Agents or their Related Parties or any of the respective correspondents, participants or assignees of the L/C Issuers shall
be liable to any Lender for: (i) any action taken or omitted in connection herewith at the request or with the approval of the Lenders or the Required Lenders, as applicable; (ii) any action taken or omitted in the absence of gross
negligence or willful misconduct as determined by a court of competent jurisdiction in a final and non-appealable judgment; or (iii) the due execution, effectiveness, validity or enforceability of any
document or instrument related to any Letter of Credit or Letter of Credit Request. Each Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided,
however, that this assumption is not intended to, and shall not, preclude any Borrower’s pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of the L/C Issuers,
the Agents or any of their Related Parties, or any of the respective correspondents, participants or assignees of the L/C Issuers, shall be liable or responsible for any of the matters described in clauses (i) through
(viii) of clause (g) of this Section 2.05; provided, however, that anything in such clauses to the contrary notwithstanding, each applicable Borrower may have a claim
against the applicable L/C Issuer, and such L/C Issuer may be liable to such Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by such Borrower which are determined by a court
of competent jurisdiction in a final and non-appealable judgment to have been caused by such L/C Issuer’s willful misconduct or gross negligence or such L/C Issuer’s willful or grossly negligent
failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In furtherance and not in limitation of the
foregoing, the L/C Issuers may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and no L/C Issuer shall be responsible for the
validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective
for any reason. 
 (i) Applicability of ISP. Unless otherwise expressly agreed by the applicable L/C Issuer and the applicable
Borrower when a Letter of Credit is issued, the rules of the ISP shall apply to such Letter of Credit. 
 (j) Conflict with L/C
Documents. In the event of any conflict between this Agreement and any L/C Document, this Agreement shall govern. 
 (k)
Letters of Credit Issued for a Borrower or Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of any Subsidiary of a Borrower, the Borrowers
shall be obligated to reimburse the applicable L/C Issuer hereunder for any and all drawings under such Letter of Credit. The Borrowers hereby acknowledge that the issuance of Letters of Credit for the account of the Subsidiaries inures to the
benefit of each Borrower, and that each Borrower’s business derives benefits from the businesses of such Subsidiaries. 
 (l)
Indemnification of L/C Issuers. (i) In addition to its other obligations under this Agreement, each Borrower hereby agrees to protect, indemnify, pay and save each L/C Issuer harmless from and against any and all claims, demands,
liabilities, damages, losses, costs, charges and expenses (including reasonable out-of-pocket fees, charges and disbursements of counsel) that such L/C Issuer may incur
or be subject to as a consequence, direct or indirect, of (A) the issuance of any Letter of Credit or (B) the failure of such L/C Issuer to honor a drawing under a Letter of Credit as a result of any act or omission, whether rightful or
wrongful, of any present or future de jure or de facto government or Governmental Authority (all such acts or omissions herein called “Government Acts”). 

  
 70 

 (ii) As between the Borrowers and each L/C Issuer, the Borrowers shall assume all risks of
the acts or omissions of or the misuse of any Letter of Credit by the beneficiary thereof. No L/C Issuer shall be responsible for: (A) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party
in connection with the application for and issuance of any Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged; (B) the validity or sufficiency of any instrument
transferring or assigning or purporting to transfer or assign any Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, that may prove to be invalid or ineffective for any reason; (C) failure of the
beneficiary of a Letter of Credit to comply fully with conditions required in order to draw upon a Letter of Credit; (D) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex or
otherwise, whether or not they be in cipher; (E) errors in interpretation of technical terms; (F) any loss or delay in the transmission or otherwise of any documents required in order to make a drawing under a Letter of Credit or of the
proceeds thereof; and (G) any consequences arising from causes beyond the control of the applicable L/C Issuer, including, without limitation, any Government Acts. None of the above shall affect, impair, or prevent the vesting of any L/C
Issuer’s rights or powers hereunder. 
 (iii) In furtherance and extension and not in limitation of the specific provisions hereinabove
set forth, any action taken or omitted by an L/C Issuer, under or in connection with any Letter of Credit or the related certificates, if taken or omitted in good faith, shall not put such L/C Issuer under any resulting liability to any Borrower or
any other Loan Party. It is the intention of the parties that this Agreement shall be construed and applied to protect and indemnify each L/C Issuer against any and all risks involved in the issuance of any Letter of Credit, all of which risks are
hereby assumed by the Loan Parties, including, without limitation, any and all risks, whether rightful or wrongful, of any present or future Government Acts. No L/C Issuer shall in any way be liable for any failure by such L/C Issuer or anyone else
to pay any drawing under any Letter of Credit as a result of any Government Acts or any other cause beyond the control of such L/C Issuer. 

(iv) Nothing in this clause (l) is intended to limit the Reimbursement Obligation of any Borrower contained in this
Section 2.05. The obligations of each Borrower under this clause (l) shall survive the termination of this Agreement. No act or omission of any current or prior beneficiary of a Letter of Credit
shall in any way affect or impair the rights of any L/C Issuer to enforce any right, power or benefit under this Agreement. 
 (v)
Notwithstanding anything to the contrary contained in this clause (l), the Borrowers shall have no obligation to indemnify any L/C Issuer in respect of any liability incurred by such L/C Issuer arising solely out of the
gross negligence or willful misconduct of such L/C Issuer, as determined by a court of competent jurisdiction in a final and non-appealable judgment. Nothing in this Agreement shall relieve any L/C Issuer of
any liability to any Borrower in respect of any action taken by such L/C Issuer which action constitutes gross negligence or willful misconduct of such L/C Issuer, as determined by a court of competent jurisdiction in a final and non-appealable judgment. 
 (m) Resignation of an L/C Issuer. An L/C Issuer may resign at any
time by giving 30 days’ notice to the Administrative Agent, the Revolving Lenders and MKS; provided, however, that any such resignation shall not affect the rights or obligations of such L/C Issuer with respect to
Letters of Credit issued by it prior to such resignation. Upon any such resignation, MKS shall (within 60 days after such notice of resignation) either appoint a successor or terminate the unutilized L/C Commitment of such L/C Issuer;
provided, however, that, if MKS elects to terminate such unutilized L/C Commitment, MKS may at any time thereafter that the Revolving Commitments are in effect reinstate such L/C Commitment in connection with the appointment of another
L/C Issuer. Upon the acceptance of any appointment as an L/C Issuer hereunder by a successor L/C Issuer, such successor shall succeed to 

  
 71 

 
and become vested with all the interests, rights and obligations of the retiring L/C Issuer and the retiring L/C Issuer shall be discharged from its obligations to issue Letters of Credit
hereunder. The acceptance of any appointment as L/C Issuer hereunder by a successor L/C Issuer shall be evidenced by an agreement entered into by such successor, in a form reasonably satisfactory to MKS and the Administrative Agent, and, from and
after the effective date of such agreement, (i) such successor shall be a party hereto and have all the rights and obligations of an L/C Issuer under this Agreement and the other Loan Documents and (ii) references herein and in the other
Loan Documents to such L/C Issuer shall be deemed to refer to such successor or to any previous L/C Issuer, or to such successor and all previous L/C Issuers, as the context shall require. After the resignation of an L/C Issuer hereunder, the
retiring L/C Issuer shall remain a party hereto and shall continue to have all the rights and obligations of an L/C Issuer under this Agreement and the other Loan Documents with respect to Letters of Credit issued by it prior to such resignation,
but shall not be required to issue additional Letters of Credit. 
 (n) Reporting. Each L/C Issuer (other than the
Administrative Agent) will report in writing to the Administrative Agent (i) on the first Business Day of each month, the aggregate face amount of Letters of Credit issued by it and outstanding as of the last Business Day of the preceding
month, (ii) on or prior to each Business Day on which such L/C Issuer expects to issue, amend, renew or extend any Letter of Credit, the date of such issuance or amendment, and the aggregate face amount of Letters of Credit to be issued,
amended, renewed or extended by it and outstanding after giving effect to such issuance, amendment, renewal or extension (and such L/C Issuer shall advise the Administrative Agent on such Business Day whether such issuance, amendment, renewal or
extension occurred and whether the amount thereof changed), (iii) on each Business Day on which such L/C Issuer makes any L/C Disbursement, the date and amount of such L/C Disbursement and (iv) on any Business Day on which the Borrower
fail to reimburse an L/C Disbursement required to be reimbursed to such L/C Issuer on such day, the date and amount of such failure. 

Section 2.06 Interest. 

(a) Rate Options Applicable to Loans. Each Revolving Borrowing shall be comprised of Base Rate Loans or Eurodollar Loans, as the
applicable Borrower may request pursuant to Section 2.02. Revolving Borrowings of more than one Type may be outstanding at the same time; provided, however, that no Borrower may request any Revolving Borrowing
that, if made, would result in an aggregate of more than ten separate Groups of Eurodollar Loans being outstanding hereunder at any one time. For this purpose, Loans having different Interest Periods, regardless of whether commencing on the same
date, shall be considered separate Groups. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment and before and after the commencement of any proceeding under any Insolvency or Liquidation
Proceeding. 
 (b) Rates Applicable to Loans. Subject to the provisions of clause (c) below,
(i) each Eurodollar Loan shall bear interest on the outstanding principal amount thereof for each Interest Period applicable thereto at a rate per annum equal to the sum of the Adjusted Eurodollar Rate for such Interest Period plus the
then Applicable Margin for Eurodollar Loans and (ii) each Base Rate Loan shall bear interest on the outstanding principal amount thereof for each day from the date such Loan is made as, or converted into, a Base Rate Loan until it becomes due
or is converted into a Loan of any other Type, at a rate per annum equal to the Base Rate for such day plus the then Applicable Margin for Base Rate Loans. 

(c) Additional Interest. If any Loan or interest thereon or any fee described in Section 2.11 or any
other amount is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, such overdue amount shall thereafter bear interest at the Default Rate to the full extent permitted by
applicable Laws. 

  
 72 

 (d) Interest Payments. Interest on each Loan shall be due and payable in
arrears on each Interest Payment Date applicable thereto and at such other times as may be specified herein. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the
commencement of any proceeding under any Insolvency or Liquidation Proceeding. Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable upon demand. 

(e) Determination and Notice of Interest Rates. The Administrative Agent shall promptly notify the applicable Borrower and the
Lenders of the interest rate applicable to any Interest Period for Eurodollar Loans upon determination of such interest rate. At any time when Base Rate Loans are outstanding, the Administrative Agent shall notify the applicable Borrower and the
Lenders of any change in the Prime Rate used in determining the Base Rate promptly following the public announcement of such change. Any notice with respect to Eurodollar Loans shall, without the necessity of the Administrative Agent so stating in
such notice, be subject to the provisions of the definition of “Applicable Margin” providing for adjustments in the Applicable Margin applicable to such Loans after the beginning of the Interest Period applicable thereto. 

Section 2.07 Extension and Conversion. 

(a) Continuation and Conversion Options. The Loans included in each Revolving Borrowing shall bear interest initially at the type
of rate allowed by Section 2.06 and as specified by the applicable Borrower in the applicable Notice of Borrowing. Thereafter, the applicable Borrower shall have the option, on any Business Day, to elect to change or
continue the type of interest rate borne by each Group of Loans (subject in each case to the provisions of Article III and Section 2.07(d)), as follows: 

(i) if such Loans are Base Rate Loans, such Borrower may elect to convert such Loans to Eurodollar Loans as of any Business Day; and 

(ii) if such Loans are Eurodollar Loans, such Borrower may elect to continue such Loans as Eurodollar Loans for an additional Interest Period
or in the case of Eurodollar Loans denominated in Dollars, elect to convert such Loans to Base Rate Loans, in each case subject to Section 3.05 if any such continuation or conversion is effective on any day other than the
last day of the then current Interest Period applicable to such Loans. 
 Each such election shall be made by delivering a notice, substantially in the form
of Exhibit A-3 hereto (a “Notice of Extension/Conversion”), which notice shall not thereafter be revocable by any Borrower, to the Administrative Agent not later
than 12:00 p.m. on the third Business Day (or the fourth Business Day in the case of Eurodollar Loans denominated in an Alternative Currency) before the conversion or continuation selected in such notice is to be effective. A Notice of
Extension/Conversion may, if it so specifies, apply to only a portion of the aggregate principal amount of the relevant Group of Loans; provided that (i) such portion is allocated ratably among the Loans comprising such Group and
(ii) the portion to which such Notice of Borrowing applies, and the remaining portion to which it does not apply, are each $1,000,000 or any larger multiple of $1,000,000. 

(b) Contents of Notice of Extension/Conversion. Each Notice of Extension/ Conversion shall specify: 

(i) the Group of Loans (or portion thereof) to which such notice applies; 

(ii) the date on which the conversion or continuation selected in such notice is to be effective, which shall comply with the applicable
clause of Section 2.07(a) above; 

  
 73 

 (iii) if the Loans comprising such Group are to be converted, the new Type of Loans and, if
the Loans being converted are to be Eurodollar Loans, the duration of the next succeeding Interest Period applicable thereto; and 
 (iv) if
such Loans are to be continued as Eurodollar Loans for an additional Interest Period, the duration of such additional Interest Period. 
 Each Interest
Period specified in a Notice of Extension/Conversion shall comply with the provisions of the definition of the term “Interest Period.” If no Notice of Extension/Conversion is timely received prior to the end of an Interest Period for any
Group of Eurodollar Loans, the Borrowers shall be deemed to have elected that such Group be converted to Base Rate Loans as of the last day of such Interest Period. 

(c) Notification to Lenders. Upon receipt of a Notice of Extension/Conversion from a Borrower pursuant to
Section 2.07(a), the Administrative Agent shall promptly notify each Lender of the contents thereof. 
 (d)
Limitation on Conversion/Continuation Options. No Borrower shall be entitled to elect to convert any Loans to, or continue any Loans for an additional Interest Period as, Eurodollar Loans if the aggregate principal amount of any Group
of Eurodollar Loans created or continued as a result of such election would be less than $1,000,000. If an Event of Default shall have occurred and be continuing when a Borrower delivers notice of such election to the Administrative Agent, such
Borrower shall not be entitled to elect to convert any Eurodollar Loans to, or continue any Eurodollar Loans for an Interest Period as, Eurodollar Loans having an Interest Period in excess of one (1) month. 

Section 2.08 Maturity. The Revolving Loans shall mature on the Revolving Termination Date, and any
Revolving Loans, Protective Advances and L/C Obligations then outstanding (together with accrued interest thereon and fees in respect thereof) shall be due and payable on such date. 

Section 2.09 Prepayments. 

(a) Voluntary Prepayment of Loans. The Borrowers shall have the right to voluntarily prepay Loans in whole or in part from time
to time, subject to Section 3.05 but otherwise without premium or penalty; provided that each partial prepayment of Loans shall be in a minimum principal amount of $1,000,000 or a whole multiple of $100,000 in excess
thereof. Each payment pursuant to this Section shall be applied as directed by the Borrower. 
 (b) Mandatory Prepayments. 

(i) Line Cap. If on any date (x) the aggregate Revolving Outstandings exceed the Revolving Committed Amount or (y) the
aggregate Revolving Outstandings (excluding Protective Advances) exceed the Line Cap, the Borrowers shall repay, and there shall become due and payable (together with accrued interest thereon), on the second Business Day immediately following such
date an aggregate principal amount of Loans and (if applicable) Protective Advances in such amounts as are necessary to eliminate such shortfall. If the outstanding Loans and Protective Advances have been repaid in full, the Borrowers shall Cash
Collateralize L/C Obligations to eliminate such shortfall. In determining the aggregate Revolving Outstandings for purposes of this Agreement, L/C Obligations shall be reduced to the extent that they are Cash Collateralized as contemplated by this
clause (i). Each prepayment of Loans required pursuant to this clause (i) shall be applied ratably among outstanding Loans based on the respective amounts of principal then outstanding. Each Cash
Collateralization of L/C Obligations required by this clause (i) shall be applied ratably among L/C Obligations based on the respective amounts thereof then outstanding. 

  
 74 

 (ii) Alternative Currency Sublimit. If on any date the aggregate Revolving
Outstandings denominated in an Alternative Currency exceed 105% of the Alternative Currency Sublimit, the Borrowers shall repay, and there shall become due and payable (together with accrued interest thereon), on the second Business Day
immediately following such date an aggregate principal amount of Loans denominated in an Alternative Currency in such amounts as are necessary to eliminate such shortfall. Each prepayment of Loans denominated in any Alternative Currency required
pursuant to this clause (ii) shall be applied ratably among outstanding Loans denominated in such Alternative Currency based on the respective amounts of principal then outstanding. 

(iii) [RESERVED] 
 (iv)
Cash Dominion Period. At all times after the commencement and during the continuance of a Cash Dominion Period, and notification thereof by the Administrative Agent to MKS (subject to the provisions of
Section 6.11(b)), on each Business Day the Administrative Agent shall apply all immediately available funds credited on behalf of the Borrowers to a Payment Account or such other account directed by the Administrative Agent
pursuant to Section 6.11(b) in accordance with first, clauses FIRST through SIXTH of Section 8.03(a) (but disregarding Reported Cash Management Obligations
and Reported Swap Secured Obligations), second, if an Event of Default exists, clause SEVENTH of Section 8.03(a) and third, in accordance with clauses NINTH
and TENTH of Section 8.03(a). 
 (v) Application of Mandatory Prepayments. All amounts
required to be paid pursuant to this Section 2.09(b) (other than Section 2.09(b)(iv)) shall be applied first to the Protective Advances, second, to the Revolving Loans and
third, to Cash Collateralize L/C Obligations (if there are any). 
 (vi) Payments Cumulative. Except as otherwise
expressly provided in this Section 2.09, payments required under any subsection or clause of this Section 2.09 are in addition to payments made or required under any other subsection or clause of
this Section 2.09. 
 (c) Notice of Mandatory Prepayment Events. The Borrowers shall use commercially
reasonable efforts to give to the Administrative Agent at least one (1) Business Day’s prior written or telecopy notice of each and every prepayment required under Section 2.09(b)(iii), including the estimated
amount of Net Cash Proceeds expected to be received therefrom. 
 (d) Notices of Prepayments. The Borrowers shall notify the
Administrative Agent, by 11:00 a.m., at least three (3) Business Days (or four (4) Business Days in the case of Eurodollar Loans denominated in an Alternative Currency) prior to the date of voluntary prepayment in the case of
Eurodollar Loans and at least one (1) Business Day prior to the date of voluntary prepayment in the case of Base Rate Loans. Each notice of prepayment shall be substantially in the form of Exhibit O (but such notice
may be conditional on the occurrence of an event to the extent specified in such notice) and shall specify the prepayment date, the principal amount to be prepaid, whether the Loan to be prepaid is a Eurodollar Loan or a Base Rate Loan and, in the
case of a Eurodollar Loan, the Interest Period of such Loan. The Administrative Agent will promptly notify each Lender of its receipt of each such notice, and of the amount of such Lender’s pro rata share, if any, thereof. Once such notice is
given by any Borrower, the Borrowers shall make such prepayment and the payment amount specified in such notice shall be due and payable as specified therein. All prepayments of Loans and Protective Advances under this
Section 2.09 (other than Section 2.09(b)(iv)) shall be accompanied by accrued interest on the principal amount being prepaid to the date of payment, together with any additional amounts required
pursuant to Section 3.05. 

  
 75 

 Section 2.10 Adjustment of Commitments. 

(a) Optional Termination or Reduction of Commitments (Pro rata). MKS may from time to time permanently reduce or terminate the
Revolving Committed Amount in whole or in part (in minimum aggregate amounts of $1,000,000 or any whole multiple of $500,000 in excess thereof (or, if less, the full remaining amount of the then applicable Revolving Committed Amount)) upon three
Business Days’ prior written or telecopy notice to the Administrative Agent (which notice may be conditional on the occurrence of an event to the extent specified in such notice); provided, however, that no such termination or
reduction shall be made which would cause the Revolving Outstandings to exceed the Revolving Committed Amount as so reduced, unless, concurrently with such termination or reduction, the Revolving Loans are repaid (and, after the Revolving Loans have
been paid in full, the L/C Obligations are Cash Collateralized) to the extent necessary to eliminate such excess. The Administrative Agent shall promptly notify each affected Lender of the receipt by the Administrative Agent of any notice from MKS
pursuant to this Section 2.10(a). Any partial reduction of the Revolving Committed Amount pursuant to this Section 2.10(a) shall be applied to the Revolving Commitments of the Lenders pro rata
based upon their respective Revolving Commitment Percentages. The Borrowers shall pay to the Administrative Agent for the account of the Lenders in accordance with the terms of Section 2.11, on the date of each termination
or reduction of the Revolving Committed Amount, any fees accrued through the date of such termination or reduction on the amount of the Revolving Committed Amount so terminated or reduced. 

(b) Termination. The Revolving Commitments and the related L/C Commitments of the relevant L/C Issuers shall terminate
automatically on the Revolving Termination Date. 
 (c) General. The Borrowers shall pay to the Administrative Agent for the
account of the Lenders in accordance with the terms of this Section 2.10, on the date of each termination or reduction of the Revolving Committed Amount, the Commitment Fee accrued through the date of such termination or
reduction on the amount of the Revolving Committed Amount so terminated or reduced. 
 Section 2.11
Fees. 
 (a) Commitment Fee. The Borrowers shall pay to the Administrative Agent for the account of each
Revolving Lender (other than a Defaulting Lender) a fee (the “Commitment Fee”) on such Lender’s Revolving Commitment Percentage of the daily Unused Revolving Committed Amount, computed at a per annum rate equal to the
Commitment Fee Percentage. The Commitment Fee shall commence to accrue on the Closing Date and shall be due and payable in arrears on the last Business Day of each March, June, September and December (and on any date that the Revolving Committed
Amount is reduced as provided in Section 2.10(a) (solely with respect to the amount of the Revolving Committed Amount so reduced) and on the Revolving Termination Date) for the period ending on each such date;
provided that the first such payment shall be due on March 29, 2019. 
 (b) Letter of Credit Fees. 

(i) Letter of Credit Fee. The Borrowers shall pay to the Administrative Agent for the account of each Revolving Lender that is
not a Defaulting Lender a fee (the “Letter of Credit Fee”) on such Lender’s Revolving Commitment Percentage of the average daily maximum amount available to be drawn under each Letter of Credit (whether or not such maximum
amount is then in effect under such Letter of Credit) computed at a per annum rate for each day from the date of issuance to the date of expiration equal to the Applicable Margin for Eurodollar Loans in effect from time to time;
provided, however, that any Letter of Credit Fees otherwise payable for the account of a Defaulting Lender with respect to any Letter of Credit as to which such Defaulting Lender has not provided Cash

  
 76 

 
Collateral pursuant to Section 2.05 shall instead be payable, to the maximum extent permitted by applicable Law, to the other Lenders in accordance with the upward
adjustments in their respective Applicable Percentages allocable to such Letter of Credit pursuant to Section 2.17(a)(iv), with the balance of such fee, if any, payable to the L/C Issuers for their own respective accounts.
The Letter of Credit Fee will be computed on a quarterly basis in arrears and shall be due and payable on the last Business Day of each March, June, September and December, commencing with the first of such dates to occur after the date of issuance
of such Letter of Credit, and on the Letter of Credit Expiration Date and thereafter on demand. 
 (ii) Fronting Fee and Documentary
and Processing Charges Payable to the L/C Issuers. The Borrowers shall pay directly to each L/C Issuer for its own account a fronting fee with respect to each Letter of Credit issued by such L/C Issuer, at a rate of 0.125% per
annum, computed on the daily amount available to be drawn under such Letter of Credit on a quarterly basis in arrears. Such fronting fee shall be due and payable on the last Business Day of each March, June, September and December, commencing
with the first such date after the issuance of such Letter of Credit, and on the Letter of Credit Expiration Date and thereafter on demand. 

(iii) L/C Issuer Fees. In addition to the Letter of Credit Fee payable pursuant to clause (i) above,
the Borrowers promise to pay to each L/C Issuer for its own account without sharing by the other Lenders the letter of credit fronting and negotiation fees agreed to by the Borrowers and such L/C Issuer from time to time and the customary charges
from time to time agreed to by the Borrowers and such L/C Issuer with respect to the issuance, amendment, transfer, administration, cancellation and conversion of, and drawings under, such Letters of Credit (collectively, the “L/C Issuer
Fees”). L/C Issuer Fees are due when earned and payable on demand and are nonrefundable. 
 (c) Other Fees. The
Borrowers shall pay to the Arrangers and the Administrative Agent for their own respective accounts fees in the amounts and at the times specified in the applicable Fee Letter. Such fees shall be fully earned when paid and shall not be refundable
for any reason whatsoever. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever except as otherwise agreed. 

Section 2.12 Pro rata Treatment. Except to the extent otherwise provided herein, 

(a) Loans. Each Revolving Borrowing, each payment or prepayment of principal of or interest on any Loan, each payment of fees
(other than the L/C Issuer Fees retained by an L/C Issuer for its own account, and the administrative fees retained by the Agents for their own account), each reduction of the Revolving Committed Amount and each conversion or continuation of any
Loan, shall be allocated pro rata among the relevant Lenders in accordance with the respective Revolving Commitment Percentages of such Lenders (or, if the Commitments of such Lenders have expired or been terminated, in accordance with the
respective principal amounts of the outstanding Loans, participation interests in Protective Advance Exposure of such Lenders and Participation Interests of such Lenders); provided that, in the event any amount paid to any Lender pursuant to
the foregoing is rescinded or must otherwise be returned by the Administrative Agent, each Lender shall, upon the request of the Administrative Agent, repay to the Administrative Agent the amount so paid to such Lender, with interest for the period
commencing on the date such payment is returned by the Administrative Agent until the date the Administrative Agent receives such repayment at a rate per annum equal to the greater of the Overnight Rate and a rate determined by the
Administrative Agent in accordance with banking industry rules on interbank compensation. 

  
 77 

 (b) Letters of Credit. Each payment of L/C Obligations shall be allocated to
each Revolving Lender pro rata in accordance with its Revolving Commitment Percentage; provided that, if any Revolving Lender shall have failed to pay its applicable pro rata share of any L/C Disbursement as required under
Section 2.05(e)(v) or (vi), then any amount to which such Revolving Lender would otherwise be entitled pursuant to this clause (b) shall instead be payable to the L/C Issuers. 

Section 2.13 Sharing of Payments by Lenders. If any Lender shall, by exercising any right of setoff or
counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of the Loans made by it or of its participation interests in Protective Advance Exposure or of its Participation Interests in L/C Obligations held by it
resulting in such Lender’s receiving payment of a proportion of the aggregate amount of such Loans or such participation interests or such Participation Interests greater than its pro rata share thereof as provided herein, then the Lender
receiving such greater proportion shall (i) notify the Administrative Agent of such fact and (ii) purchase (for cash at face value) participation in the Loans of the other Lenders, subparticipations in the participation interests in the
Protective Advance Exposure of the other Lenders and subparticipations in the Participation Interests in L/C Obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be
shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing thereon; provided that: 

(i) if any such participations or subparticipations are purchased and all or any portion of the payment giving rise thereto is recovered, such
participations or subparticipations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and 

(ii) the provisions of this Section shall not be construed to apply to (x) any payment made by or on behalf of any Borrower pursuant to
and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), (y) the application of Cash Collateral provided for in Section 2.05
or 2.16, or (z) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or subparticipations in its participation interests in the Protective Advance Exposure or
subparticipations in its Participation Interests in L/C Obligations to any assignee or participant. 
 Each Loan Party consents to the
foregoing and agrees, to the extent it may effectively do so under applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against such Loan Party rights of setoff and counterclaim with respect
to such participation as fully as if such Lender were a direct creditor of such Loan Party in the amount of such participation. 

Section 2.14 Payments Generally; Administrative Agent’s Clawback.

 (a) Payments by the Borrowers. All payments to be made by any Borrower shall be made without condition or deduction for any
counterclaim, defense, recoupment or setoff. Each payment of principal of and interest on Loans, L/C Obligations and fees hereunder shall be paid not later than 1:00 p.m. Eastern time (or, in the case of an Alternative Currency, the Applicable
Time) on the date when due, in Dollars and in Federal or other funds immediately available to the Administrative Agent at the account designated by it by notice to the applicable Borrower. Payments received after 1:00 p.m. Eastern time (or, in
the case of an Alternative Currency, the Applicable Time) shall be deemed to have been received on the next Business Day, and any applicable interest or fee shall continue to accrue. The Administrative Agent may, in its sole discretion, distribute
such payments to the applicable Lenders on the date of receipt thereof, if such payment is received prior to 1:00 p.m. Eastern time (or, in the case of an Alternative Currency, the Applicable Time); otherwise the Administrative Agent may, in
its sole discretion, distribute such payment to the applicable Lenders on the date of receipt thereof or on the immediately succeeding Business Day. Whenever any payment hereunder shall be due on a day which is not a Business Day, the

  
 78 

 
date for payment thereof shall be extended to the next succeeding Business Day (and such extension of time shall be reflected in computing interest or fees, as the case may be), unless (in the
case of Eurodollar Loans) such Business Day falls in another calendar month, in which case the date for payment thereof shall be the next preceding Business Day. If the date for any payment of principal is extended by operation of Law or otherwise,
interest thereon shall be payable for such extended time. If, for any reason, any Borrower is prohibited by any Law from making any required payment hereunder in an Alternative Currency, such Borrower shall make such payment in Dollars in the Dollar
Equivalent of the Alternative Currency payment amount) and without setoff or counterclaim. 
 (b) Presumption by the Administrative
Agent. Unless the Administrative Agent shall have received notice from the applicable Borrower prior to the date on which any payment is due to the applicable Lenders or any L/C Issuer hereunder that such Borrower will not make such payment,
the Administrative Agent may assume that such Borrower has made such payment on such date in accordance herewith, and may, in reliance upon such assumption, distribute to the applicable Lenders or the applicable L/C Issuers, as the case may be, the
amount due. In such event, if such Borrower has not in fact made such payment, then each of the applicable Lenders or the applicable L/C Issuers, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the
amount so distributed to such Lender or L/C Issuer, in immediately available funds with interest thereon, for each day from and including the date such amount is distributed to but excluding the date of payment to the Administrative Agent at the
greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. A notice of the Administrative Agent to any Lender with respect to any amount owing under this
clause (b) shall be conclusive, absent manifest error. 
 (c) Failure to Satisfy Conditions
Precedent. If any Lender makes available to the Administrative Agent funds for any Loan to be made by such Lender as provided in the foregoing provisions of this Article II, and such funds are not made available to
a Borrower by the Administrative Agent because the conditions to the applicable Credit Extension set forth in Article IV are not satisfied or waived in accordance with the terms hereof, the Administrative Agent shall return
such funds promptly (in like funds as received from such Lender) to such Lender without interest. 
 (d) Obligations of Lenders
Several. The obligations of the Lenders hereunder to make Loans, to purchase participation interests in the Protective Advance Exposure and to purchase Participation Interests in the Letters of Credit are several and not joint. The failure
of any Lender to make a Loan required to be made by it as part of any Borrowing hereunder or to fund a participation interest in the Protective Advance Exposure or to fund a Participation Interest shall not relieve any other Lender of its
obligation, if any, hereunder to make any Loan on the date of such Borrowing or fund any such participation interest in the Protective Advance Exposure or fund any such Participation Interest, but no Lender shall be responsible for the failure of
any other Lender to make the Loan to be made by such other Lender on such date of Borrowing or fund such other Lender’s participation interest in the Protective Advance Exposure or fund such other Lender’s Participation Interest. 

(e) Funding Source. Nothing herein shall be deemed to obligate any Lender to obtain the funds for any Loan in any particular
place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any Loan in any particular place or manner. 

(f) Computations. All computations of interest for Base Rate Loans when the Base Rate is determined by the Prime Rate shall be
made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All computations of Commitment Fees and other computations of fees and interest shall be made on the basis of
a 360-day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365-day year).
Interest shall 

  
 79 

 
accrue on each Loan for the day on which Loan is made (or converted or continued), and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid;
provided that any Loan that is repaid on the same day on which it is made (or continued or converted) shall, subject to clause (a) above, bear interest for one day. Each determination by the Administrative Agent of
an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error. 

Section 2.15 Increase in Commitments. 

(a) Increase in Commitments. MKS may by written notice to the Administrative Agent elect to increase the Revolving Commitments
(each increase, an “Incremental Facility”; the commitments thereunder are referred to as “Incremental Commitments”); provided that the total aggregate amount for all such Incremental Facilities shall not (as
of any date of incurrence thereof) exceed $50,000,000. Each Incremental Facility incurred under this Section 2.15 shall be in an aggregate principal amount that is not less than $10,000,000. Each such notice shall specify
(x) the date (each, an “Increase Effective Date”) on which MKS proposes that the Incremental Facility shall be effective, which shall be a date not less than five (5) Business Days after the date on which such notice is
delivered to the Administrative Agent and (y) the identity of each Eligible Assignee to whom MKS proposes any portion of such Incremental Facility be allocated and the amounts of such allocations; provided that any existing Lender
approached to provide all or a portion of the Incremental Facility may elect or decline, in its sole discretion, to provide such portion of the Incremental Facility. 

(b) Conditions. The Incremental Facilities shall become effective, as of such Increase Effective Date; provided that: 

(i) each of the conditions set forth in Section 4.02 shall be satisfied; 

(ii) no Event of Default shall have occurred and be continuing or would result from the Revolving Borrowings to be made on the Increase
Effective Date; and 
 (iii) MKS shall deliver or cause to be delivered a certificate of a Responsible Officer certifying as to compliance
with the foregoing conditions. 
 (c) Increase Joinder. The Incremental Commitments shall be effected by a joinder agreement
(the “Increase Joinder”) executed by the Borrowers, the Administrative Agent and each Lender making such Incremental Commitment, in form attached hereto or otherwise in form and substance satisfactory to each of them. The Increase
Joinder may, without the consent of any other Lenders, effect such amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the opinion of the Administrative Agent, to effect the provisions of this
Section 2.15. On any Increase Effective Date on which the Commitments are increased by Incremental Facility, the participations held by the Lenders in the Protective Advance Exposure and the L/C Obligations immediately
prior to such increase will be reallocated so as to be held by the Lenders ratably in accordance with their respective Applicable Percentages after giving effect to such increase. If, on any Increase Effective Date, there are any Loans outstanding,
the Borrowers shall prepay such Loans in accordance with this Agreement on such date to the extent necessary to effect such reallocation (but the Borrowers may finance such prepayment with a concurrent borrowing of Loans from the Lenders in
accordance with their Applicable Percentages after giving effect to the Incremental Facility effected on such date). 
 (d) Equal and
Ratable Benefit. The Loans and Commitments established pursuant to this paragraph shall constitute Loans and Commitments under, and shall be entitled to all the benefits afforded by, this Agreement and the other Loan Documents, and shall,
without limiting the foregoing, benefit equally and ratably from the Guaranty Agreement and security interests created by the Collateral 

  
 80 

 
Documents. The Loan Parties shall take any actions reasonably required by the Administrative Agent to ensure and/or demonstrate that the Lien and security interests granted by the Collateral
Documents continue to be perfected under the UCC or otherwise after giving effect to the establishment of any such new Commitments, including, without limitation, delivery to the Administrative Agent of (i) customary legal opinions, board
resolutions and officer’s certificates substantially consistent with those delivered on the Closing Date (conformed as appropriate) and in any event, reasonably satisfactory to the Administrative Agent and (ii) reaffirmation agreements
and/or such amendments to the Collateral Documents as may be reasonably requested by the Administrative Agent in order to ensure that the Lenders under the Incremental Facilities are provided the benefits of the applicable Loan Documents. 

(e) MIRE Event. Each of the parties hereto acknowledges and agrees that, if there are any Mortgaged Properties, any increase,
extension or renewal of any of the Commitments or Loans (including the provision of Incremental Commitments) or any other incremental or additional credit facilities hereunder, but excluding (a) any continuation or conversion of borrowings,
(b) the making of any Revolving Loans, or (c) the issuance, renewal or extension of Letters of Credit shall be subject to and conditioned upon: (i) the prior delivery of all flood hazard determination certifications, acknowledgements
and evidence of flood insurance and other flood-related documentation with respect to such Mortgaged Properties as required by the Flood Insurance Laws and as otherwise reasonably required by the Administrative Agent and (ii) the Administrative
Agent shall have received written confirmation from the Lenders that flood insurance due diligence and flood insurance compliance have been completed by the Lenders (such written confirmation not to be unreasonably conditioned, withheld or delayed).

 Section 2.16 Cash Collateral. 

(a) Obligation to Cash Collateralize. Upon the request of the Administrative Agent or the applicable L/C Issuer if, as of the
date that is ten (10) Business Days prior to the Revolver Termination Date, any L/C Obligation for any reason remains outstanding or there are any L/C Borrowings outstanding or there are any outstanding Letters of Credit, or as otherwise
required pursuant to Section 2.05, Section 2.09(b), Section 2.17 or Section 8.02, the Borrowers shall, in each case, immediately Cash
Collateralize the then Outstanding Amount of all L/C Obligations in an amount not less than the Minimum Collateral Amount. At any time that there shall exist a Defaulting Lender, immediately upon the written request of the Administrative Agent or
any applicable L/C Issuer (with a copy to the Administrative Agent), the Borrowers shall Cash Collateralize all Fronting Exposure of such L/C Issuer with respect to such Defaulting Lender (determined after giving effect to
Section 2.17(a)(iv) and any Cash Collateral provided by such Defaulting Lender) in an amount not less than the Minimum Collateral Amount with respect thereto. 

(b) Grant of Security Interest. All Cash Collateral (other than credit support not constituting funds subject to deposit) shall
be maintained in blocked, non-interest bearing deposit accounts at the Collateral Agent. Each Borrower, and to the extent provided by any Lender, such Lender, hereby grants to (and subjects to the control of)
the Collateral Agent, for the benefit of the Collateral Agent, the applicable L/C Issuers and the applicable Lenders, and agrees to maintain, a first priority security interest in all such cash, deposit accounts and all balances therein, and all
other property so provided as collateral pursuant hereto, and in all proceeds of the foregoing, all as security for the obligations to which such Cash Collateral may be applied pursuant to Section 2.16(c). If at any time
the Collateral Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Collateral Agent as herein provided, or that the total amount of such Cash Collateral is less than the Minimum Collateral Amount and
other obligations secured thereby, the Borrowers or the relevant Defaulting Lender will, promptly upon demand by the Collateral Agent, pay or provide to the Collateral Agent additional Cash Collateral in an amount sufficient to eliminate such
deficiency. 

  
 81 

 (c) Application. Notwithstanding anything to the contrary contained in this
Agreement, Cash Collateral provided under any of this Section 2.16 or Sections 2.05, 2.09(b), 2.17, 8.02 or otherwise in respect of Letters of Credit shall be held and applied
to the satisfaction of the specific L/C Obligations to fund participations therein (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so
provided, prior to any other application of such property as may be provided for herein. 
 (d) Release. Cash Collateral (or
the appropriate portion thereof) provided to reduce Fronting Exposure or other obligations shall be released promptly following (i) the elimination of the applicable Fronting Exposure or other obligations giving rise thereto (including by the
termination of Defaulting Lender status of the applicable Lender (or, as appropriate, its assignee following compliance with Section 10.06(b))) or (ii) the determination by the Collateral Agent that there exists excess
Cash Collateral; provided, however, (x) that Cash Collateral furnished by or on behalf of a Loan Party shall not be released during the continuance of a Default or Event of Default (and following application as provided in this
Section 2.16 may be otherwise applied in accordance with Section 8.03) and (y) the Person providing Cash Collateral, the Administrative Agent and the applicable L/C Issuer may agree that Cash
Collateral shall not be released but instead held to support future anticipated Fronting Exposure or other obligations. 

Section 2.17 Defaulting Lenders. 

(a) Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender,
then, until such time as that Lender is no longer a Defaulting Lender, to the extent permitted by applicable Law: 
 (i) Waivers and
Amendments. That Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in Section 10.01. 

(ii) Reallocation of Payments. Any payment of principal, interest, fees or other amounts received by the Administrative Agent
for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VIII or otherwise or received by the Administrative Agent from such Defaulting Lender pursuant to
Section 10.08) shall be applied at such time or times as may be determined by the Administrative Agent as follows: 

FIRST, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; 

SECOND, to prepay any Protective Advance Exposure with respect to such Defaulting Lender; 

THIRD, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to each applicable L/C Issuer hereunder; 

FOURTH, to Cash Collateralize the L/C Issuers’ Fronting Exposure with respect to such Defaulting Lender in accordance with
Section 2.16; 
 FIFTH, as MKS may request (so long as no Default or Event of Default exists), to the funding of
any Loan in respect of which that Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; 

  
 82 

 SIXTH, if so determined by the Administrative Agent and MKS, to be held in a deposit account
and released pro rata in order to (x) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans and Protective Advance Exposure under this Agreement and (y) Cash Collateralize the L/C Issuers’
future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement, in accordance with Section 2.16; 

SEVENTH, to the payment of any amounts owing to the Lenders or each applicable L/C Issuer as a result of any judgment of a court of competent
jurisdiction obtained by any Lender or any applicable L/C Issuer against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; 

EIGHTH, so long as no Default or Event of Default exists, to the payment of any amounts owing to any Borrower as a result of any judgment of a
court of competent jurisdiction obtained by such Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and 

NINTH, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; 

provided that if (x) such payment is a payment of the principal amount of any Loans or L/C Borrowings in respect of which such Defaulting Lender
has not fully funded its appropriate share and (y) such Loans or L/C Borrowings were made at a time when the conditions set forth in Section 4.02 were satisfied or waived, such payment shall be applied solely to pay
the Loans of, and L/C Borrowings owed to, all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or L/C Borrowings owed to, such Defaulting Lender. Any payments,
prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.17(a)(ii) shall be deemed paid
to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto. 
 (iii) Certain Fees. (x) No
Defaulting Lender shall be entitled to receive any Commitment Fee payable pursuant to Section 2.11(a) for any period during which such Lender is a Defaulting Lender (and the Borrowers shall not be required to pay any such
fee that otherwise would have been required to have been paid to such Defaulting Lender) and (y) each Defaulting Lender shall be limited in its right to receive Letter of Credit Fees as provided in Section 2.11(b).

 (iv) Reallocation of Participations to Reduce Protective Advance Exposure and Fronting Exposure. All or any part of such
Defaulting Lender’s participation in Protective Advance Exposure and L/C Obligations shall be reallocated among the non-Defaulting Lenders in accordance with their respective Revolving Commitment
Percentages (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that (x) the conditions set forth in Section 4.02 are satisfied at the time of such reallocation (and, unless
the Borrowers shall have otherwise notified the Administrative Agent at such time, the Borrowers shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such reallocation does not cause the
sum of, without duplication, the aggregate Outstanding Amount of the Revolving Loans of any non-Defaulting Lender plus such Lender’s Revolving Commitment Percentage of the Protective Advance
Exposure plus such Lender’s Revolving Commitment Percentage of the Outstanding Amount of all L/C Obligations at such time at such time to exceed such Lender’s Revolving Commitment. No reallocation hereunder shall constitute a waiver
or release of any claim of any party hereunder against a Defaulting Lender arising from such Lender having become a Defaulting Lender, including any claim of a non-Defaulting Lender as a result of such non-Defaulting Lender’s increased exposure following such reallocation. 

  
 83 

 (b) Defaulting Lender Cure. If the Borrowers, the Administrative Agent and
each L/C Issuer agree in writing that a Defaulting Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set
forth therein (which may include arrangements with respect to any Cash Collateral), such Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative
Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Protective Advances and Letters of Credit to be held on a pro rata basis by the Lenders in accordance with their Applicable Percentages (without giving
effect to Section 2.17), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of any
Borrower while such Lender was a Defaulting Lender; provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or
release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender. 
 (c) New Letters of
Credit. So long as any Revolving Lender is a Defaulting Lender, no L/C Issuer shall be required to issue, extend or amend any Letter of Credit unless it is satisfied that it will have no Fronting Exposure after giving effect thereto. 

Section 2.18 Protective Advances. 

(a) Subject to the limitations set forth below, the Administrative Agent is authorized by the Borrower and the Lenders, from time to time in
the Administrative Agent’s Permitted Discretion (but shall have absolutely no obligation to), after the occurrence and during the continuance of a Default or an Event of Default, to make Loans to the Borrowers, on behalf of all Lenders, which
the Administrative Agent, in its Permitted Discretion, deems necessary or desirable (i) to preserve or protect the Collateral, or any portion thereof, (ii) to enhance the likelihood of, or maximize the amount of, repayment of the Loans and
other Finance Obligations, or (iii) to pay any other amount chargeable to or required to be paid by the Borrower pursuant to the terms of this Agreement, including payments of reimbursable expenses (including costs, fees, and expenses as
described in Section 10.04) and other sums payable under the Loan Documents (any of such Loans are herein referred to as “Protective Advances”); provided that, as of the date of the making of any
Protective Advance, the aggregate amount of outstanding Protective Advances shall not exceed 5% of the Commitments outstanding as of such date; provided further that the Revolving Outstandings at any time shall not exceed the
Revolving Committed Amount. Protective Advances may be made even if the conditions precedent set forth in Section 4.02 have not been satisfied. The Protective Advances shall be secured by the Liens in favor of the
Collateral Agent in and to the Collateral and shall constitute Finance Obligations hereunder. All Protective Advances shall be Base Rate Loans. The Administrative Agent’s authorization to make Protective Advances may be revoked at any time by
the Required Lenders. Any such revocation must be in writing and shall become effective prospectively upon the Administrative Agent’s receipt thereof. At any time (i) the amount equal to (A) the Line Cap minus (B) the
Revolving Outstandings (calculated, with respect to any Defaulting Lender, as if such Defaulting Lender had funded its Revolving Commitment Percentage of all outstanding Revolving Loans) exceeds the amount of any Protective Advance and (ii) the
conditions precedent set forth in Section 4.02 have been satisfied, the Administrative Agent may request the Revolving Lenders to make a Revolving Loan to repay a Protective Advance. At any other time the Administrative
Agent may require the Lenders to fund their risk participations described in Section 2.18(b). 

  
 84 

 (b) Upon the making of a Protective Advance by the Administrative Agent (whether before or
after the occurrence of a Default or Event of Default), each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from the Administrative Agent, without recourse or warranty, an
undivided interest and participation in such Protective Advance in proportion to its Revolving Commitment Percentage. From and after the date, if any, on which any Lender is required to fund its participation in any Protective Advance purchased
hereunder, the Administrative Agent shall promptly distribute to such Lender such Lender’s Revolving Commitment Percentage of all payments of principal and interest and all proceeds of Collateral received by the Administrative Agent in respect
of such Protective Advance (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s participating interest was outstanding and funded and, in the case of principal and interest
payments, to reflect such Lender’s pro rata portion of such payment if such payment is not sufficient to pay the principal of and interest on all Protective Advances then due). 

ARTICLE III. 
 TAXES,
YIELD PROTECTION AND ILLEGALITY 
 Section 3.01 Taxes. 

(a) Payments Free of Taxes. Any and all payments by or on account of any Loan Party under any Loan Document shall be made free
and clear of, and without deduction or withholding for or on account of, any Taxes, unless otherwise required by law. If any applicable withholding agent shall be required by law (as determined in the good faith discretion of the applicable
withholding agent) to deduct or withhold any Taxes from or in respect of any sum payable under any Loan Document to any Lender Party or any Agent, (i) the applicable withholding agent shall be entitled to make all such deductions or
withholdings, (ii) the applicable withholding agent shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law, and (iii) to the extent the deduction or withholding is on
account of Indemnified Taxes or Other Taxes, the amounts so payable by the applicable Loan Party to the Agent or such Lender Party shall be increased as may be necessary so that, after such withholding agent has made all required deductions or
withholdings of Indemnified Taxes and Other Taxes (including deductions or withholdings applicable to additional sums payable under this Section 3.01), such Lender Party or such Agent, as the case may be, shall have
received an amount equal to the sum it would have received had no such deductions or withholdings been made. 
 (b) Payment of Other
Taxes by the Borrowers. Without limiting the provisions of clause (a) above, the Borrowers shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law or, at the option
of the Administrative Agent, timely reimburse it for the payment of any Other Taxes. 
 (c) Evidence of Payments. Within thirty
(30) days after the date of any payment of Indemnified Taxes or Other Taxes by a Loan Party to a Governmental Authority pursuant to this Section 3.01, such Loan Party shall deliver to the Administrative Agent the
original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. 

(d) Indemnification by the Borrowers. The Borrowers shall indemnify each Agent and each Lender Party for and hold them harmless
against the full amount of Indemnified Taxes payable in connection with any payments made by or on account of any Loan Party under any Loan Document and (without any duplication) Other Taxes (including Indemnified Taxes or Other Taxes imposed or
asserted on or attributable to amounts payable under this Section 3.01), and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally
imposed or asserted by the relevant Governmental Authority. This indemnification 

  
 85 

 
shall be made within ten (10) days after written demand therefor. A reasonably detailed certificate as to the amount of such payment or liability delivered to MKS by a Lender Party (with a
copy to the Administrative Agent), or by an Agent on its own behalf, shall be conclusive absent manifest error. 
 (e) Treatment of
Refunds. If any Agent or any Lender Party determines, in its reasonable discretion, that it has received a refund of any Indemnified Taxes or Other Taxes as to which it has been indemnified by any Loan Party or with respect to which any Loan
Party has paid additional amounts pursuant to this Section 3.01, it shall pay to a Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amount paid, by the Loan Party
under this Section 3.01 with respect to the Indemnified Taxes or Other Taxes giving rise to such refund), net of all reasonable out-of-pocket
expenses (including Taxes) of the Administrative Agent or such Lender Party, attributable to such refund and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided that the
Loan Party, upon the request of the Administrative Agent or such Lender Party, agrees to repay the amount paid over to any Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative
Agent or such Lender Party in the event the Administrative Agent or such Lender Party is required to repay such amount to such Governmental Authority. This paragraph shall not be construed to require the Administrative Agent or any Lender Party to
make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to any Loan Party or any other Person. Notwithstanding anything to the contrary in this clause (e), in no event will
the indemnified party be required to pay any amount to an indemnifying party pursuant to this clause (e) the payment of which would place the indemnified party in a less favorable net
after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the
indemnification payments or additional amounts with respect to such Tax had never been paid. 
 (f) Status of Lenders. 

(i) Each Lender Party that is entitled to an exemption from or reduction of any applicable withholding Tax with respect to payments made under
any Loan Document shall deliver to MKS and the Administrative Agent, at the time or times prescribed by law or reasonably requested by MKS or the Administrative Agent, such properly completed and executed documentation prescribed by law or
reasonably requested by MKS or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender Party, if reasonably requested by MKS or the Administrative Agent, shall
deliver such other documentation prescribed by applicable law or reasonably requested by MKS or the Administrative Agent as will enable MKS or the Administrative Agent to determine whether or not such Lender Party is subject to backup withholding or
information reporting requirements. Each Lender Party shall, whenever a lapse in time or change in circumstances renders such documentation (including any specific documents required below in this Section 3.01(f)) obsolete,
expired or inaccurate in any respect, deliver promptly to MKS and the Administrative Agent updated or other appropriate documentation (including any new documentation reasonably requested by MKS or the Administrative Agent) or promptly notify MKS
and the Administrative Agent in writing of its inability to do so. Notwithstanding anything to the contrary in the preceding three sentences, the completion, execution and submission of such documentation (other than such documentation set forth in
Section 3.01(f)(ii)(A) through (ii)(E) and (iii) below) shall not be required if in the Lender Party’s reasonable judgment such completion, execution or submission would subject such Lender
Party to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender Party. 

  
 86 

 (ii) Without limiting the generality of the foregoing any Lender Party shall, if it is
legally eligible to do so, deliver to MKS and the Administrative Agent on or prior to the date on which such Lender Party becomes a party hereto (and from time to time thereafter upon the reasonable request of MKS or the Administrative Agent), two
duly completed and executed copies of whichever of the following is applicable: 
 (A) in the case of a Lender Party that is
a United States person (as such term is defined in Section 7701(a)(30) of the Code), IRS Form W-9 certifying that such Lender Party is exempt from U.S. federal backup withholding; 

(B) in the case of a Non-U.S. Lender claiming the benefits of an income tax treaty
to which the United States is a party, IRS Form W-8BEN or W-8BEN-E establishing an exemption from, or reduction of,
U.S. federal withholding Tax pursuant to such tax treaty; 
 (C) in the case of a
Non-U.S. Lender claiming an exemption from U.S. federal income Taxes for income that is effectively connected with a U.S. trade or business, executed originals of IRS Form W-8ECI; 
 (D) in the case of a
Non-U.S. Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit F-1 (any such certificate, a “U.S. Tax Compliance Certificate”) and (y) IRS Form W-8BEN or W-8BEN-E; 
 (E) to the extent that a Non-U.S. Lender is not the beneficial owner (for example, where the Non-U.S. Lender is a partnership or participating Lender), IRS
Form W-8IMY of the Non-U.S. Lender, accompanied by IRS Form W-8ECI, IRS
Form W-8BEN or W-8BEN-E, a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-2 or Exhibit F-3, IRS Form W-9, and/or other certification documents from each beneficial
owner that would be required under this Section 3.01(f) if such beneficial owner were a Lender, as applicable; provided that if the Non-U.S. Lender is a partnership (and
not a participating Lender) and one or more direct or indirect partners of such Non-U.S. Lender are claiming the portfolio interest exemption, such
Non-U.S. Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-4 on behalf of such direct and
indirect partners; or 
 (F) any other form prescribed by applicable law as a basis for claiming exemption from or a
reduction in U.S. federal withholding Taxes, together with such supplementary documentation as may be prescribed by applicable law to permit MKS or the Administrative Agent to reasonably determine the withholding or deduction required to be
made. 
 (iii) If a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed under
FATCA if the Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Administrative Agent and
MKS at the time or times prescribed by law, and at such other time or times reasonably requested by the Administrative Agent or MKS, the documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the
Code) and such additional documentation reasonably requested by the Administrative Agent or MKS as may be necessary for the Administrative Agent or any Borrower to comply with its obligations under FATCA and to determine whether the Lender has
complied with the Lender obligations under FATCA, or to determine the amount to deduct and withhold from the payment. Solely for purposes of this clause (iii), “FATCA” shall include any amendments made to FATCA
after the date of this Agreement. 

  
 87 

 (iv) Notwithstanding any other provision of this Section 3.01(f),
a Lender Party shall not be required to deliver any form or other documentation that such Lender Party is not legally eligible to deliver. 

Section 3.02 Illegality. If any Lender determines that any Law has made it unlawful, or that any
Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund Loans whose interest is determined by reference to the Adjusted Eurodollar Rate, or to determine or charge interest
rates based upon the Adjusted Eurodollar Rate, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the London interbank market, then, upon notice
thereof by such Lender to MKS (through the Administrative Agent), (i) any obligation of such Lender to make or continue Eurodollar Loans or to convert Base Rate Loans to Eurodollar Loans shall be suspended, and (ii) if such notice asserts
the illegality of such Lender making or maintaining Base Rate Loans the interest rate on which is determined by reference to the Adjusted Eurodollar Rate component of the Base Rate, the interest rate on which Base Rate Loans of such Lender shall, if
necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Adjusted Eurodollar Rate component of the Base Rate, in each case until such Lender notifies the Administrative Agent and MKS that the
circumstances giving rise to such determination no longer exist. Upon receipt of such notice, (x) the Borrowers shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or convert all Eurodollar Loans of such Lender
to Base Rate Loans (the interest rate on which Base Rate Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Adjusted Eurodollar Rate component of the Base Rate),
either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such Eurodollar Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such Eurodollar Loans and (y) if
such notice asserts the illegality of such Lender determining or charging interest rates based upon the Adjusted Eurodollar Rate, the Administrative Agent shall during the period of such suspension compute the Base Rate applicable to such Lender
without reference to the Adjusted Eurodollar Rate component thereof until the Administrative Agent is advised in writing by such Lender that it is no longer illegal for such Lender to determine or charge interest rates based upon the Adjusted
Eurodollar Rate. Upon any such prepayment or conversion, the Borrowers shall also pay accrued interest on the amount so prepaid or converted, together with any additional amounts required pursuant to Section 3.05. 

Section 3.03 Inability To Determine Rates. If on or prior to the first day of any Interest Period for
any Eurodollar Loan denominated in any Applicable Currency: 
 (i) the Administrative Agent determines (which determination shall be
conclusive) that by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the applicable Eurodollar Rate (including because the LIBO Rate is not available or published on a current basis)
for such Interest Period; or 
 (ii) Lenders having 50% or more of the aggregate amount of the Commitments advise the Administrative
Agent that the Eurodollar Rate as determined by the Administrative Agent will not adequately and fairly reflect the cost to such Lenders of funding their Eurodollar Loans denominated in such currency for such Interest Period; 

the Administrative Agent shall forthwith give notice thereof to MKS and the Lenders, whereupon, until the Administrative Agent notifies MKS that the
circumstances giving rise to such suspension no longer exist, (x) the obligations of the Lenders to make Eurodollar Loans denominated in such Applicable 

  
 88 

 
Currency, or to continue or convert outstanding Loans as or into Eurodollar Loans denominated in such Applicable Currency, shall be suspended and (y) each outstanding Eurodollar Loan
denominated in such Applicable Currency, if Dollars, shall be converted into a Base Rate Loan, or if in an Alternative Currency, shall be prepaid, in each case on the last day of the then current Interest Period applicable thereto. If
clause (i) or (ii) of this Section 3.03 applies, unless MKS notifies the Administrative Agent prior to 12:00 p.m. on the Business Day of the date of any Eurodollar Loan denominated
in Dollars for which a Notice of Borrowing has previously been given that it elects not to borrow on such date, such Revolving Borrowing shall instead be made as a Base Rate Borrowing in the same aggregate amount as the requested Revolving Borrowing
and shall bear interest for each day from and including the first day to but excluding the last day of the Interest Period applicable thereto at the rate applicable to Base Rate Loans for such day. Notwithstanding the foregoing, in the case of a
pending Notice of Borrowing or conversion or continuation in Eurodollar Loans denominated in an Alternative Currency as to which clause (i) or (ii) above of this Section applies, the Administrative Agent, in
consultation with the Borrowers and the relevant Lenders, may establish an alternative interest rate that reflects the all-in-cost of funds to the Administrative Agent
for funding Loans in the applicable currency and amount, and with the same Interest Period as the Eurodollar Loan requested to be made, converted or continued, as the case may be (the “Impacted Loans”), in which case, such
alternative rate of interest shall apply with respect to the Impacted Loans until (x) the Administrative Agent revokes the notice delivered with respect to the Impacted Loans, (y) the Required Lenders notify the Administrative Agent and
the Borrowers that such alternative interest rate does not adequately and fairly reflect the cost to such Lenders of funding the Impacted Loans, or (z) any Lender determines that any Law has made it unlawful, or that any Governmental Authority
has asserted that it is unlawful, for such Lender or its applicable lending office to make, maintain or fund Loans whose interest is determined by reference to such alternative rate of interest or to determine or charge interest rates based upon
such rate or any Governmental Authority has imposed material restrictions on the authority of such Lender to do any of the foregoing and as to which the Administrative Agent and the Borrowers have been provided with written notice thereof. 

If at any time the Administrative Agent determines (which determination shall be conclusive absent manifest error) that (i) the
circumstances set forth in Section 3.03(i) have arisen and such circumstances are unlikely to be temporary or (ii) the circumstances set forth in Section 3.03(i) have not arisen but the
administrator or a supervisor for the administrator of the Eurodollar Rate or a Governmental Authority having jurisdiction over the Administrative Agent has made a public statement identifying a specific date after which the administrator has ceased
or will cease to provide such benchmark or stating that Eurodollar Rate is no longer representative or shall no longer be used for determining interest rates for loans, or that the administrator has invoked or will invoke its insufficient
submissions policy, then the Administrative Agent and MKS shall endeavor to establish an alternate rate of interest to the Eurodollar Rate that gives due consideration to the then prevailing or evolving market convention for determining a rate of
interest for syndicated loans in the United States at such time, and shall enter into an amendment to this Agreement to reflect such alternate rate of interest and such other related changes to this Agreement as may be applicable. Notwithstanding
anything to the contrary in Section 10.01, such amendment shall become effective without any further action or consent of any other party to this Agreement so long as the Administrative Agent shall not have received, within
five (5) Business Days of the date notice of such alternate rate of interest is provided to the Lenders, a written notice from the Required Lenders stating that such Required Lenders object to such amendment; provided that, if such alternate
rate of interest shall be less than zero, such rate shall be deemed to be zero for the purposes of this Agreement. 

Section 3.04 Increased Costs and Reduced Return; Capital Adequacy. 

(a) Increased Costs Generally. If any Change in Law shall: 

  
 89 

 (i) impose, modify or deem applicable any reserve, special deposit, compulsory loan,
insurance charge or similar requirement against assets held by, deposits with or for the account of, or credit extended or participated in by, any Lender (or its Lending Office) (except any reserve requirement which is reflected in the determination
of the Adjusted Eurodollar Rate hereunder) or any L/C Issuer; 
 (ii) subject any Lender Party to any Taxes with respect to any Loan
Document or any Loan made pursuant to this Agreement (other than Indemnified Taxes and Other Taxes indemnified under Section 3.01, and Excluded Taxes); or 

(iii) impose on any Lender (or its Lending Office) or L/C Issuer or the London interbank market any other condition, cost or expense (other
than Taxes) affecting this Agreement or Eurodollar Loans made by such Lender or participation interest therein, or any Protective Advance or any participation interest therein, or any Letter of Credit or Participation Interest therein; 

and the result of any of the foregoing shall be to increase the cost to such Lender of making, converting to, continuing or maintaining any Eurodollar Loan or
of maintaining its obligation to make any such Loan, or to increase the cost to such Lender of participating in any Protective Advance, or to increase to cost to such L/C Issuer of participating in, issuing or maintaining any Letter of Credit (or of
maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender or such L/C Issuer, as the case may be, hereunder (whether of principal, interest or any other
amount) then, upon request of such Lender or such L/C Issuer, the Borrowers will pay to such Lender or such L/C Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or such L/C Issuer, as the case may be, for
such additional costs incurred or reduction suffered. 
 (b) Capital Requirements. If any Lender or L/C Issuer determines that
any Change in Law affecting such Lender, any of its applicable Lending Offices or its holding company or such L/C Issuer or its holding company, as the case may be, regarding capital and liquidity requirements has or would have the effect of
reducing the rate of return on capital for such Lender or its holding company or such L/C Issuer or its holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Protective
Advance Exposure held by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by any L/C Issuer, to a level below that which such Lender or its holding company or such L/C Issuer or its holding company, as
the case may be, could have achieved but for such Change in Law (taking into consideration such Lender’s or its holding company’s policies or such L/C Issuer’s or its holding company’s policies, as applicable, with respect to
capital and liquidity adequacy), then from time to time the Borrowers will pay to such Lender or such L/C Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or its holding company or such L/C Issuer or its
holding company for any such reduction suffered. 
 (c) Certificates for Reimbursement. A certificate of a Lender or an L/C
Issuer setting forth in reasonable detail the amount or amounts necessary to compensate such Lender or such L/C Issuer or its holding company, as the case may be, as specified in clause (a) or (b) above and
delivered to MKS, shall be conclusive absent manifest error. The Borrowers shall pay such Lender or such L/C Issuer, as the case may be, the amount shown as due on any such certificate promptly (but in any event within ten (10) Business Days)
after receipt thereof. 
 (d) Delay in Requests. Failure or delay on the part of any Lender or any L/C Issuer to demand
compensation pursuant to this Section shall not constitute a waiver of such Lender’s or such L/C Issuer’s right to demand such compensation; provided that the Borrowers shall not be required to

  
 90 

 
compensate a Lender or L/C Issuer pursuant to this Section for any increased costs incurred or reductions suffered more than 180 days prior to the date that such Lender or such L/C
Issuer, as the case may be, notifies MKS of the Change in Law giving rise to such increased costs or reductions, and of such Lender’s or such L/C Issuer’s intention to claim compensation therefor (except that, if the Change in Law giving
rise to such increased costs or reductions is retroactive, then the 180 day period referred to above shall be extended to include the period of retroactive effect thereof). 

Section 3.05 Compensation for Losses. Upon written demand of any Lender (with a copy to the
Administrative Agent) from time to time, setting forth in reasonable detail the basis for calculating such compensation, the Borrowers shall promptly (but in any event within ten (10) days) after such demand compensate such Lender for and hold
such Lender harmless from any loss, cost or expense incurred by it as a result of (a) any continuation, conversion, payment or prepayment of any Eurodollar Loan on a day other than the last day of the Interest Period for such Loan (whether
voluntary, mandatory, automatic, by reason of acceleration, or otherwise); (b) any failure by any Borrower (for a reason other than the failure of such Lender to make a Loan) to prepay, borrow, continue or convert any Eurodollar Loan on the
date or in the amount notified by any Borrower; (c) any assignment of such Lender’s Eurodollar Loans pursuant to Section 3.07(b) on a day other than the last day of the Interest Period therefor; or (d) any
failure by any Borrower to make payment of any Loan or reimburse any drawing under any Letter of Credit (or interest due thereon) denominated in an Alternative Currency on its scheduled due date or any payment thereof in a different currency,
including, in each case, any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained; provided that, for the
avoidance of doubt, the Borrowers shall not be obligated to compensate any Lender under this Section for any loss of anticipated profits in respect of any of the foregoing. For purposes of calculating amounts payable by the Borrowers to the Lenders
under this Section, each Lender shall be deemed to have funded each Eurodollar Loan made by it at the Adjusted Eurodollar Rate (excluding the impact of the proviso set forth in the “Adjusted Eurodollar Rate” definition) for such Loan by a
matching deposit or other borrowing in the London interbank eurodollar market for a comparable amount and for a comparable period, whether or not such Eurodollar Loan was in fact so funded. 

Section 3.06 Base Rate Loans Substituted for Affected Eurodollar Loans. If (i) the obligation of
any Lender to make, or to continue or convert outstanding Loans as or to, Eurodollar Loans has been suspended pursuant to Section 3.02 or (ii) any Lender or L/C Issuer has demanded compensation under
Section 3.04 with respect to its Eurodollar Loans, and in any such case the Borrowers shall, by at least five (5) Business Days’ prior notice to such Lender through the Administrative Agent, have elected that the
provisions of this Section 3.06 shall apply to such Lender, then, unless and until such Lender notifies MKS that the circumstances giving rise to such suspension or demand for compensation no longer exist, all Loans which
would otherwise be made by such Lender as (or continued as or converted to) Eurodollar Loans shall instead be Base Rate Loans (on which interest and principal shall be payable contemporaneously with the related Eurodollar Loans of the other
Lenders). If such Lender notifies MKS that the circumstances giving rise to such suspension or demand for compensation no longer exist, the principal amount of each such Base Rate Loan shall be converted into a Eurodollar Loan on the first day of
the next succeeding Interest Period applicable to the related Eurodollar Loans of the other Lenders. 

Section 3.07 Mitigation Obligations; Replacement of Lenders. 

(a) Designation of a Different Lending Office. If at any time (i) any Lender requires a Borrower to pay additional amounts
to any Lender or any Governmental Authority for the account of any Lender or any L/C Issuer pursuant to Section 3.01, (ii) any Lender requests compensation under Section 3.04 or (iii) any
Lender gives a notice pursuant to Section 3.02, then such Lender or L/C Issuer 

  
 91 

 
shall, as applicable, at the request of such Borrower, use reasonable efforts to designate a different Lending Office for funding or booking its Loans hereunder or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender or L/C Issuer, such designation or assignment (A) would eliminate or reduce amounts payable pursuant to
Section 3.01 or Section 3.04, as the case may be, in the future, or eliminate the need for the notice pursuant to Section 3.02, and (B) in each case, would not
subject such Lender or L/C Issuer, as the case may be, to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender or L/C Issuer, as the case may be. Each Borrower hereby agrees to pay all reasonable costs and
expenses incurred by any Lender or L/C Issuer in connection with any such designation or assignment. 
 (b) Replacement of Lenders or
L/C Issuers. If at any time (i) any Borrower is required to pay additional amounts to any Lender, L/C Issuer or any Governmental Authority for the account of any Lender or L/C Issuer pursuant to Section 3.01,
(ii) any Lender or L/C Issuer requests compensation under Section 3.04, (iii) any Lender or L/C Issuer gives a notice pursuant to Section 3.02, (iv) any Lender or L/C Issuer is a
Defaulting Lender or (v) any Lender or L/C Issuer is a Non-Consenting Lender, then such Borrower may, at its sole expense and effort, upon notice to the Administrative Agent and such Lender or L/C Issuer,
replace such Lender or L/C Issuer by causing such Lender or L/C Issuer (and such Lender or L/C Issuer shall be obligated) to assign pursuant to Section 10.06(b) (with the processing and recording fee under
Section 10.06(b)(iii) to be paid by the Borrowers in such instance) all of its rights and obligations under this Agreement and the other Loan Documents to one or more Eligible Assignees; provided that: 

(A) (i) neither the Administrative Agent nor any Lender shall have any obligation to find a replacement assignee and
(ii) the Borrowers shall have paid to the Administrative Agent the assignment fee specified in Section 10.06(b) (unless waived by the Administrative Agent); 

(B) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, funded participations
in outstanding Protective Advances and funded participations in outstanding L/C Borrowings, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under
Section 3.05) from the applicable assignee (to the extent of such outstanding principal, funded participations and accrued interest and fees) or the Borrowers (in the case of all other amounts); 

(C) in the case of any such assignment resulting from payments required to be made pursuant to
Section 3.01 or a claim for compensation under Section 3.02 or Section 3.04, such assignment will result in a reduction in such payments or compensation thereafter or, in
the case of any such assignment resulting from a notice pursuant to Section 3.02, such assignment will eliminate the need for such notice; 

(D) such assignment does not conflict with applicable Law; and 

(E) in the case of any such assignment resulting from a Lender becoming a
Non-Consenting Lender, the applicable assignee shall be deemed to have consented to the applicable amendment, waiver or consent. 

In connection with any such assignment contemplated by this Section, if any such Lender does not execute and deliver to the Administrative
Agent a duly executed Assignment and Assumption pursuant to Section 10.06(b) reflecting such assignment within two (2) Business Days of the date on which the applicable assignee executes and delivers such Assignment
and Assumption to such Lender, 

  
 92 

 
then such Lender shall be deemed to have executed and delivered such Assignment and Assumption without any action on the part of such Lender, whereupon such assignment shall become effective upon
payment to such Lender of all amounts owing to such Lender under clause (B) or (C) above (which amounts shall be calculated by the Administrative Agent and shall be conclusive absent manifest error) and
compliance with the other applicable requirements pursuant to Section 10.06(b). 
 Notwithstanding anything in
this Section to the contrary, any Revolving Lender that acts as an L/C Issuer may not be replaced hereunder at any time it has any Letter of Credit outstanding hereunder unless arrangements reasonably satisfactory to such Lender (including the
furnishing of a back-up standby letter of credit in form and substance, and issued by an issuer, reasonably satisfactory to such L/C Issuer or the depositing of cash collateral into a cash collateral account
in amounts and pursuant to arrangements reasonably satisfactory to such L/C Issuer) have been made with respect to such outstanding Letter of Credit. 

(c) A Lender Party shall not be required to make any such assignment if, prior to the Borrowers contacting any potential replacement Lender
Parties, the circumstances entitling any Borrower to replace such Lender cease to apply. 
 Section 3.08
Survival. All of the Borrowers’ obligations under this Article III shall survive termination of the Commitments and repayment of all other Senior Credit Obligations hereunder.

to be reasonable by the preparer thereof at the time made (it being understood and agreed that projections as to future events are not to be viewed as facts or guaranties of future performance, that actual results during the period or periods
covered by such projections may differ from the projected results and that such differences may be material and that the Loan Parties make no representation and warranty that such projections will in fact be realized). 

Section 5.15 Compliance with Law. Each of the Borrowers and its Restricted Subsidiaries is in

Borrower nor any of its Restricted Subsidiaries nor any of their respective material properties or assets is in default with respect to any judgment, writ, injunction, decree or order of any court or other Governmental Authority which, individually
or in the aggregate, could reasonably be expected to result in a Material Adverse Effect. As of the Closing Date, neither any Borrower nor any of its Restricted Subsidiaries has received any written communication from any Governmental Authority that
alleges that any of the Borrowers or any of its Restricted Subsidiaries is not in compliance in any material respect with any Law, except for allegations that have been satisfactorily resolved and are no longer outstanding or which, individually or
in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. 
 Section 5.16

(on a consolidated basis) are Solvent. 
 Section 5.19 Collateral Documents. 

(a) Article 9 Collateral. The Security Agreement, when executed and delivered, is effective to
create in favor of the Collateral Agent, for the benefit of the Finance Parties, a legal, valid and enforceable security interest in the Collateral described therein and, when financing statements in appropriate form are filed in the offices
specified on Schedule 7 to the Perfection Certificate and the Pledged Securities are delivered to the Collateral Agent, the Security Agreement shall constitute a fully perfected Lien on all right, title and interest of the grantors thereunder
in such of the Collateral in which a security interest can be created under Article 9 of the UCC and can be perfected under Article 9 of the UCC by filing or by possession thereof, in each case prior and superior in right to any other
Person, other than with respect to Permitted Liens, and except for (i) certain items of Collateral with respect to which such Lien may be perfected only by possession thereof where the failure of the Collateral Agent to have possession thereof
is expressly permitted pursuant to the Security Agreement and (ii) certain items of Collateral located in or otherwise subject to foreign law where the grant of a Lien or priority and perfection thereof in accordance with the UCC may not be
recognized or enforceable. 

  
 102 

 (b) Intellectual Property. When (i) financing statements in the
appropriate form are filed in the offices specified on Schedule 7 to the Perfection Certificate, (ii) the Patent Security Agreement, substantially in the form of Exhibit II to the Security Agreement and the Trademark Security
Agreement, substantially in the form of Exhibit III to the Security Agreement, are each filed in the United States Patent and Trademark Office and (iii) the Copyright Security Agreement, substantially in the form of Exhibit IV to the
Security Agreement, is filed in the United States Copyright Office, then, to the extent that Liens may be perfected by such filings, the Security Agreement shall constitute a fully perfected first priority Lien on all right, title and interest of
the grantors thereunder in the United States patents, trademarks, copyrights, licenses and other intellectual property rights covered in such agreements (it being understood that subsequent recordings in the United States Patent and Trademark Office
and the United States Copyright Office may be necessary to perfect a lien on U.S. issued patents, patent applications, registered trademarks, trademark applications and copyrights acquired by the Loan Parties after the Closing Date). 

(c) Status of Liens. The Collateral Agent, for the benefit of the Finance Parties, has the Liens provided for in the Collateral
Documents and, subject to the filing by the Collateral Agent of continuation statements to the extent required by the UCC and to the qualifications and limitations set forth in clauses (a) and (b) above, the
Collateral Documents are sufficient to constitute valid and continuing liens of record and first priority perfected security interests in all the Collateral (other than Permitted Liens and subject to the Intercreditor Agreement) referred to therein,
except (i) as priority may be affected by Permitted Liens as a result of the Collateral Agent’s failure to maintain possession of any stock certificates, promissory notes or other instruments delivered to it under the Collateral Documents,

perfection set forth in the Collateral Documents.

create, in favor of the Collateral Agent, for its benefit and the benefit of the Finance Parties, legal, valid and enforceable first priority Liens on all of the Loan Parties’ right, title and interest in and to the Mortgaged Properties
thereunder and the proceeds thereof, subject only to Permitted Liens, and when the Mortgages are filed in the offices specified in the local counsel opinion delivered with respect thereto in accordance with the provisions of
Section 6.09, the Mortgages shall constitute fully perfected Liens on all right, title and interest of the Loan Parties in the Mortgaged Properties and the proceeds thereof, in each case prior and superior in right to any
other Person, other than Permitted Liens.

 (c) the occurrence of any ERISA Event or
Foreign Benefit Event that, alone or together with any other ERISA Events or Foreign Benefit Events that have occurred, could reasonably be expected to result in a Material Adverse Effect; and 

(d) any other development that results in, or would reasonably be expected to have a Material Adverse Effect. 

Section 6.03 Existence; Conduct of Business. The Borrowers will, and will cause each of its Restricted
Subsidiaries to, do or cause to be done all things necessary to preserve, renew and keep in full force and effect its legal existence and the rights, qualifications, licenses, permits, privileges, franchises, governmental authorizations and
intellectual property rights material to the conduct of its business, and maintain all requisite authority to conduct its business in each jurisdiction in which its business is conducted; except in each case (x) to the extent (other than with
respect to the preservation of the existence of MKS) that failure to do so would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect or (y) pursuant to any merger, consolidation, liquidation,
dissolution or Disposition permitted by Article VII. 
 Section 6.04 Payment of
Tax Obligations. Each Borrower will, and will cause each of its Restricted Subsidiaries to, pay its Tax liabilities, that, if not paid, would reasonably be expected to result in a Material Adverse Effect before the same shall become
delinquent or in default, except where (a) the validity or amount thereof is being contested in good faith by appropriate proceedings, (b) such Borrower or such Restricted Subsidiary has set aside on its books adequate reserves with
respect thereto in accordance with GAAP and (c) the failure to make payment pending such contest could not reasonably be expected to result in a Material Adverse Effect. 

Section 6.05 Maintenance of Properties; Insurance. (a) MKS will, and will cause each of its

compatible with the following standards), with such deductibles and covering such risks as are prudent in the reasonable business judgment of MKS’s officers and (ii) all insurance required pursuant to the Mortgages; provided that,
notwithstanding the foregoing, in no event shall MKS or any Restricted Subsidiary be required to obtain or maintain insurance that is more restrictive than its normal course of practice. Each such policy

  
 107 

 
of insurance shall as appropriate, (i) name the Collateral Agent as an additional insured thereunder as its interests may appear and/or (ii) in the case of each casualty insurance
policy, contain a mortgagee/loss payable clause or endorsement that names the Collateral Agent as the mortgagee/loss payee thereunder.

Administrative Agent (pursuant to a request made through the Administrative Agent), at reasonable times upon reasonable prior notice (but not more than once annually if no Event of Default shall exist), to visit and inspect its properties, to
examine and make extracts from its books and records, including examination of its environmental assessment reports and Phase I or Phase II studies, if any, and to discuss its affairs, finances and condition with its officers, all at such reasonable
times, as often as reasonably requested and at the expense of the Borrowers. Each Borrower acknowledges that the Administrative Agent, after exercising its rights of inspection, may prepare and distribute to the Lenders certain reports pertaining to
any Borrower and its Restricted Subsidiaries’ assets for internal use by the Administrative Agent and the Lenders. 
 (b) At reasonable
times during normal business hours and upon reasonable prior notice that the Administrative Agent requests, independently of or in connection with the visits and inspections provided for in clause (a) above, (x) the
Administrative Agent may conduct (or engage third parties to conduct) such field examinations, verifications and evaluations as the Administrative Agent may deem necessary or appropriate and (y) so long as any amount of Eligible Inventory is
included in the Borrowing Base, each Loan Party and each Restricted Subsidiary shall grant access to the Administrative Agent (including employees of the Administrative Agent or any consultants, accountants, lawyers and appraisers retained by the
Administrative Agent) to such Person’s books, records, accounts and Inventory so that the Administrative Agent or an appraiser retained by the Administrative Agent may conduct an inventory appraisal; provided that the Borrowers shall
only be required to cover the costs of such periodic field examinations and inventory appraisals as follows: 
 (i) in any calendar year, no
more than one such field examination and (so long as any amount of Eligible Inventory is included in the Borrowing Base) one such appraisal shall be at the Borrowers’ expense; provided that if at the time of the commencement of any field

any amount of Eligible Inventory is included in the Borrowing Base) up to one additional appraisal during the twelve month period after such time shall be at the Borrowers’ expense; and 

  
 108 

 (ii) at any time after the occurrence and during the continuation of an Event of Default,
as many appraisals and field examinations as the Administrative Agent may reasonably request shall be at the Borrowers’ expense. 

Section 6.07 Compliance with Laws. Each Borrower will, and will cause the Acquired Business and each
Restricted Subsidiary of the foregoing, to comply with all laws, rules, regulations and orders of any Governmental Authority applicable to it or its property, in each case except where the failure to do so, individually or in the aggregate, would
not reasonably be expected to result in a Material Adverse Effect. 
 Section 6.08 Use of Proceeds.
Each Borrower has or will use the proceeds of the Loans and will use the Letters of Credit solely for the purposes set forth in Section 5.17. No part of the proceeds of any Loan have or will be used, whether directly or
indirectly, for any purpose that entails a violation of any of the Regulations of the Board of Governors of the Federal Reserve System, including Regulations T, U and X. 

Section 6.09 Subsidiary Guarantors; Pledges; Additional Collateral; Further Assurances. 

(a) Within the time periods specified in the last paragraph of this Section 6.09, after (i) any Person becomes a
Restricted Subsidiary that is not an Excluded Subsidiary or an Excluded Tax Subsidiary, (ii) any Excluded Subsidiary (other than an Excluded Tax Subsidiary) that is not an Unrestricted Subsidiary or an Excluded Tax Subsidiary ceases to be an
Excluded Subsidiary or (iii) an Excluded Tax Subsidiary that is not an Unrestricted Subsidiary or an Excluded Subsidiary ceases to be an Excluded Tax Subsidiary (each, a “New Loan Party”) (including, in each case, for the
avoidance of doubt, a Restricted Subsidiary that is no longer an Excluded Subsidiary), in each case, the Borrower shall promptly provide the Administrative Agent with written notice thereof and shall cause each such New Loan Party to deliver to the
Administrative Agent (x) a guaranty or a joinder to the Guaranty Agreement in form and substance reasonably satisfactory to the Administrative Agent, guaranteeing the Loan Parties’ obligations under the Finance Documents and (y) a
joinder to all applicable Collateral Documents then in existence, in each case as specified by, and in form and substance reasonably satisfactory to, the Administrative Agent, securing payment of all the Finance Obligations of such New Loan Party
under the Finance Documents, accompanied by appropriate corporate resolutions, other corporate documentation and customary legal opinions as may be reasonably requested by, and in form and substance reasonably satisfactory to, the Administrative
Agent and its counsel. 
 (b) Each Borrower will, and will cause each other Loan Party to, execute and deliver, or cause to be executed and
delivered, to the Administrative Agent such documents, agreements and instruments, and will take or cause to be taken such further actions (including the filing and recording of financing statements, fixture filings, Mortgages and other documents),
which may be required by law or which the Administrative Agent may, from time to time, reasonably request to carry out the terms and conditions of this Agreement and the other Loan Documents and to ensure perfection and priority of the Liens created
by the Collateral Documents, all at the expense of the Borrower. 
 (c) If any asset constituting Collateral is acquired by a Loan Party
after the Closing Date (other than Excluded Property and assets constituting Collateral under the Collateral Documents that become subject to the Lien in favor of the Collateral Agent upon acquisition thereof), the Borrowers will notify the
Administrative Agent thereof, and, if requested by the Administrative Agent, the Borrowers will cause such Collateral to be subject to a Lien securing the Finance Obligations and will take, and cause the other Loan Parties to take, such actions as
shall be necessary or reasonably requested by the Administrative Agent to grant and perfect such Liens, including actions described in clause (c) above, all at the expense of the Borrowers; provided that, with
respect to Equity Interests, such actions will be limited to those specified in clause (b) above. 

  
 109 

 (d) Notwithstanding the foregoing, with respect to (x) any property (other than
Excluded Property), owned on or acquired after the Closing Date, the Loan Parties shall have one hundred twenty (120) days after the date hereof or date of acquisition thereof as applicable, or (y) any New Loan Party, the Loan Parties
shall have ninety (90) days after the date such Person becomes a New Loan Party (or in each case, such later date as may be agreed upon by the Administrative Agent in the exercise of its reasonable discretion with respect thereto), in each case
of the foregoing, to take the actions required by this Section. 
 (e) Notwithstanding the foregoing, the Administrative Agent shall not
enter into any Mortgage in respect of any real property acquired by any Loan Party after the Closing Date until (x) the date that occurs 45 days after the Administrative Agent has delivered to the Lenders (which may be delivered electronically)
the following documents in respect of such real property: (i) a completed flood hazard determination from a third party vendor, (ii) if such real property is located in a “special flood hazard area,” (A) a notification to the
applicable Loan Party of that fact and (if applicable) notification to the applicable Loan Party that flood insurance is not available and (B) evidence of receipt by the applicable Loan Party of such notice, and (iii) if such notice is
required to be provided to the applicable Loan Party and flood insurance is available in the community in which such real property is located, evidence of flood insurance, and (y) the Administrative Agent shall have received written
confirmation from the Lenders that flood insurance due diligence and flood insurance compliance has been completed by the Lenders (such written confirmation not to be unreasonably conditioned, withheld or delayed). 

Section 6.10 Designation of Subsidiaries. MKS may, at any time from and after the Closing Date,
designate any Restricted Subsidiary as an Unrestricted Subsidiary or any Unrestricted Subsidiary as a Restricted Subsidiary; provided that (i) immediately before and after such designation, no Default or Event of Default shall
have occurred and be continuing, (ii) with respect to any such designation of any Subsidiary or Subsidiaries as Unrestricted Subsidiary whose assets included immediately before such designation in the Borrowing Base represent at least 5%
of the Borrowing Base immediately before such designation, the Payment Conditions are met (and as a condition precedent to the effectiveness of any such designation, MKS shall deliver to the Administrative Agent a certificate setting forth in
reasonable detail the calculations demonstrating such compliance), (iii) if a Restricted Subsidiary is being designated as an Unrestricted Subsidiary hereunder, such Restricted Subsidiary, together with all other Unrestricted Subsidiaries as of
such date of designation, must not have contributed greater than 10% of MKS’s Consolidated EBITDA (calculated inclusive of all Unrestricted Subsidiaries), as of the most recently ended fiscal quarter of MKS, for the period of four
(4) consecutive fiscal quarters then ended, for which financial statements have been delivered pursuant to Section 6.01 and (iv) each Subsidiary designated as a “Restricted Subsidiary” under the Term
Facility shall be designated as a Restricted Subsidiary hereunder. The designation of any Restricted Subsidiary as an Unrestricted Subsidiary after the Closing Date shall constitute an Investment by the applicable Loan Party therein at the date of
designation in an amount equal to the fair market value of the applicable Loan Party’s investment therein (as determined in good faith by MKS). The designation of any Unrestricted Subsidiary as a Restricted Subsidiary shall constitute
(i) the incurrence at the time of designation of any Indebtedness or Liens of such Subsidiary existing at such time and (ii) a return on any Investment by the applicable Loan Party in Unrestricted Subsidiaries pursuant to the preceding
sentence in an amount equal to the fair market value at the date of such designation of such Loan Party’s Investment in such Subsidiary. Notwithstanding the foregoing, MKS shall not be permitted to be an Unrestricted Subsidiary.

 Section 6.11 Cash Management.

Administrative Agent in its reasonable discretion), in form and substance reasonably satisfactory to the Administrative Agent, with the Administrative Agent and each other bank with which such Loan Party maintains any deposit account, securities
account, commodities account or lockbox (other than any Excluded Account) (collectively, the “Blocked Accounts”); and (ii) within 90 days after the Closing Date (or such later date approved by the Administrative Agent
in its reasonable discretion), MKS shall provide the Administrative Agent with a schedule of Blocked Accounts and a schedule of Excluded Accounts in each case certified by a Financial Officer of MKS.

(c) Each Blocked Account Agreement (other than the Blocked Account Agreement with respect to the Investment Account) shall require (only during
the continuance of a Cash Dominion Period and following delivery of notice of the commencement thereof from the Administrative Agent to MKS and the account bank party to such instrument or agreement) ACH or wire transfer no less frequently than once
per Business Day (but without limit on frequency if the Maturity Date shall have actually occurred) of all available cash balances and cash receipts, including the then contents or then entire ledger balance of each Blocked Account (other than the
Investment Account) (net of (i) such minimum balance as may be required to be maintained in the subject Blocked Account by the bank at which such Blocked Account is maintained and (ii) with respect to any such Blocked Account in which any
proceeds of a Revolving Borrowing or borrowing of “Incremental Term Loans” (under and as defined in the Term Credit Agreement) were deposited, solely during the two (2) Business Days immediately following the date on which such
Revolving Borrowing or borrowing was made, the amount of such proceeds remaining on deposit in such Blocked Account at the time of such ACH or wire transfer), to one or more accounts designated by and under the sole control and dominion of the
Administrative Agent (the “Payment Accounts”). Subject to the terms of the Intercreditor Agreement, (x) if an Event of Default has occurred and is continuing and after the exercise of remedies provided for in
Section 8.02 (or the Loans have automatically become immediately due and payable under Section 8.01 and the L/C Obligations have been required to be Cash Collateralized), all amounts received in a
Payment Account or such other account shall be applied (and allocated) by the Administrative Agent in accordance with Section 8.03 or (y) otherwise, all amounts received in a Payment Account or such other account shall
be applied (and allocated) by the Administrative Agent in accordance with Section 2.09(b)(iv). 
 (d) If, at any
time after the occurrence and during the continuance of a Cash Dominion Event, any cash or Cash Equivalents owned by any Loan Party (excluding amounts in payroll, trust, employee benefits and tax withholding accounts funded in the ordinary course of
business and required by applicable Law and excluding accounts the aggregate amount of deposit therein or credited thereto do not exceed $2,000,000 at any time (each such account, an “Excluded Account”)) are deposited to any account
or lockbox or held pursuant to any other arrangement, otherwise than in a Blocked Account subject to a Blocked Account Agreement, the Administrative Agent shall be entitled to require the applicable Loan Party to terminate such account or other
arrangement and have all funds therein or subject thereto transferred to a Blocked Account, and to cause all future deposits to be made to a Blocked Account. 

(e) The Loan Parties may close Blocked Accounts and/or open new Blocked Accounts without the Administrative Agent’s consent, subject to
the prompt execution and delivery to the Administrative Agent of a Blocked Account Agreement with respect to each new Blocked Account to the extent required by the provisions of this Section 6.11. The Loan Parties may open
or close Excluded Accounts at any time, without requirement of delivery of a Blocked Account Agreement without consent of the Administrative Agent. 

  
 111 

 (f) So long as no Cash Dominion Period is in effect, the Loan Parties may direct, and shall
have sole control over, the manner of disposition of funds in their respective Blocked Accounts. 
 (g) (i) Any amounts received in the
Payment Accounts (including all interest and other earnings with respect thereto, if any) at any time after Discharge of Senior Credit Obligations (other than contingent indemnification obligations as to which no claim has been asserted) and
(ii) any amounts that continue to be swept to the Payment Accounts after no Cash Dominion Event exists, shall, in each case, be remitted to the operating account of the Borrowers as specified by MKS. 

Section 6.12 Compliance with Environmental Laws. Each of the Loan Parties and Restricted Subsidiaries
will comply, and use commercially reasonable efforts to cause all lessees and other Persons occupying real property of any Loan Party to comply, with all Environmental Laws and Environmental Permits applicable to its operations, real property and
facilities; obtain and renew all material Environmental Permits applicable to its operations, real property and facilities; and conduct all investigations, response and other corrective actions to address the Release or threat of Release of
Hazardous Materials to the extent required by, and in accordance with, Environmental Laws, except in each case for any such failure which would not be reasonably expected to have a Material Adverse Effect; provided that no Loan Party or
Restricted Subsidiary shall be required to undertake any such action to the extent that its obligation to do so is being contested in good faith and by proper proceedings and appropriate reserves are being maintained with respect to such
circumstances in accordance with GAAP. 
 Section 6.13 Sanctions; International Trade Laws. Each
Borrower will maintain in effect and enforce policies and procedures designed to ensure compliance by such Borrower, its Subsidiaries, and their respective officers, directors, employees and agents with International Trade Laws and will conduct its
business in compliance with International Trade Laws, in all material respects. 
 Section 6.14 Post-Closing

 (a) (i) No Borrower nor any Restricted Subsidiary will amend, modify or waive any of its rights under any agreement or
instrument governing or evidencing any Subordinated Indebtedness to the extent such amendment, modification or waiver, taken as a whole, would reasonably be expected in the good faith judgment of MKS to be adverse in any material respect to the
Lenders; provided, however, that no amendment, modification or waiver in respect of Subordinated Indebtedness in connection with the incurrence of Permitted Refinancing Indebtedness in respect of the relevant Subordinated Indebtedness

(n) any Collateral Document shall for any reason fail to create a valid and perfected first priority security interest in any material portion
of the Collateral purported to be covered thereby (and to the extent required thereby and subject to any Permitted Liens). 

Section 8.02 Acceleration; Remedies. Upon the occurrence of and during the continuation of an Event of
Default, the Administrative Agent (or the Collateral Agent, as applicable) shall, at the request of, or may, with the consent of, the Required Lenders, take any or all of the following actions: 

(a) Termination of Commitments. Declare the Commitments terminated whereupon the Commitments shall be immediately terminated.

 (b) Acceleration of Loans. Declare the unpaid principal of and any accrued interest in respect of all Loans, any
Reimbursement Obligations arising from drawings under Letters of Credit and any and all other indebtedness or obligations of any and every kind (other than contingent indemnification obligations) owing by a Loan Party to any of the Lenders hereunder
to be due whereupon the same shall be immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Loan Parties. 

(c) Cash Collateral. Direct the Borrowers to pay (and the Borrowers agree to, upon receipt of such notice, or upon the occurrence
of an Event of Default under Section 8.01(g), (h) or (i), immediately pay) to the Collateral Agent additional cash, to be held by the Collateral Agent, for the benefit of the Lenders, in a cash collateral
account as additional security for the L/C Obligations in respect of subsequent drawings under all then outstanding Letters of Credit in an amount equal to the maximum aggregate amount which may be drawn under all Letters of Credit then outstanding
plus all accrued interest and fees thereon. 
 (d) Enforcement of Rights. Enforce any and all rights and interests created and
existing under the Loan Documents, including, without limitation, all rights and remedies existing under the Loan Documents, all rights and remedies against a Guarantor and all rights of setoff. 

  
 129 

 (e) Enforcement Rights Vested Solely in Administrative Agent and Collateral
Agent. The Lenders agree that this Agreement may be enforced only by the action of the Administrative Agent, acting upon the instructions of the Required Lenders, and, with respect to the Collateral, the Collateral Agent, and that no other
Finance Party shall have any right individually to seek to enforce any Loan Document or to realize upon the security to be granted hereby. 

Notwithstanding the foregoing, if an Event of Default specified in Section 8.01(g), (h) or
(i) shall occur, then the Commitments shall automatically terminate, all Loans, all Reimbursement Obligations under Letters of Credit, all accrued interest in respect thereof and all accrued and unpaid fees and other indebtedness or
obligations owing to the Lenders hereunder and under the other Loan Documents shall immediately become due and payable and the obligation of the Borrowers to Cash Collateralize the L/C Obligations, as aforesaid shall automatically become effective,

Section 8.03 Allocation of Payments After Event of Default. 

(a) Priority of Distributions. Each Borrower hereby irrevocably waives the right to direct the application of any and all
payments in respect of their Finance Obligations and any proceeds of Collateral after the occurrence and during the continuance of an Event of Default and agrees that, notwithstanding the provisions of Sections 2.09(b)
and 2.14, after the exercise of remedies provided for in Section 8.02 (or after the Loans have automatically become immediately due and payable and the L/C Obligations have been required to be Cash
Collateralized), all amounts collected or received on account of any Finance Obligation shall, subject to the provisions of Sections 2.16 and 2.17 and the Intercreditor Agreement, be applied by the
Administrative Agent in the following order: 
 FIRST, ratably, to pay any fees, indemnities, or expense reimbursements then owing to any
Agent and any L/C Issuer (other than in connection with Cash Management Obligations or Swap Obligations); 
 SECOND, ratably, to pay any fees
or expense reimbursements then owing to the Lender Parties (other than in connection with Cash Management Obligations or Swap Obligations), 

THIRD, ratably, to pay interest due in respect of the Protective Advances, 

FOURTH, ratably, to pay the principal of the Protective Advances, 

FIFTH, ratably, to pay interest then due and payable on the Loans (other than the Protective Advances) and unreimbursed L/C Disbursements, 

SIXTH, ratably, to pay principal on the Loans (other than the Protective Advances), unreimbursed L/C Disbursements and any amounts owing with
respect to Reported Cash Management Obligations and Reported Swap Secured Obligations, 
 SEVENTH, ratably, to pay an amount to the
Administrative Agent equal to 103% of the aggregate undrawn face amount of all outstanding Letters of Credit, to be held as Cash Collateral for such Letters of Credit, 

  
 130 

 EIGHTH, ratably, to the payment of any amounts owing with respect to Cash Management
Obligations (other than Reported Cash Management Obligations) and Swap Secured Obligations (other than Reported Swap Secured Obligations), 

NINTH, ratably, to the payment of any other Finance Obligations owing to the Administrative Agent or any Lender Party, and 

TENTH, any balance remaining after the Finance Obligations shall have been paid in full and no Letters of Credit shall be outstanding (other
than Letters of Credit which have been Cash Collateralized in accordance with the foregoing) shall be paid over to the applicable Loan Party at its account designated for such purpose by written notice by such Loan Party to the Administrative Agent
or to whomsoever else may be lawfully entitled to receive the same. 
 In carrying out the foregoing, amounts received shall be applied in the numerical
order provided until exhausted prior to application to the next succeeding category. Each payment (including each prepayment) by the Borrower on account of principal of and interest on the Revolving Loans shall be made pro rata according to the
respective outstanding principal amounts of the Revolving Loans then held by the Revolving Lenders, unless otherwise provided by this Agreement. The application of any payment pursuant to this Section 8.03 shall be made
first, to Base Rate Loans and second, to Eurodollar Loans. Each of the Administrative Agent and the Lenders shall have the continuing and exclusive right to apply and reverse and reapply any and all such proceeds and payments to any portion of the
Finance Obligations to maximize realization of the Collateral (it being understood that, notwithstanding the foregoing, in no event shall be payments be made pursuant to clause EIGHT or NINTH above prior to the
payment in full of all obligations described in clauses FIRST through SEVENTH above). 
 (b) Reliance
by Agent. For purposes of applying payments received in accordance with this Section 8.03, each Agent shall be entitled to rely upon (i) the Swap Creditors and their Affiliates for a determination of the
outstanding Swap Secured Obligations and (ii) the Cash Management Banks and their Affiliates for a determination of the outstanding Cash Management Obligations. Unless it has actual knowledge to the contrary, each Agent, in acting hereunder,
shall be entitled to assume that no Secured Cash Management Agreement and no Secured Swap Agreement is in existence. 
 ARTICLE IX.

 AGENCY PROVISIONS 

Section 9.01 Appointment and Authority. Each of the Lenders and each L/C Issuer hereby irrevocably
appoints Barclays to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the
Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. Each of the Lenders and each L/C Issuer hereby irrevocably appoints Barclays to act on its behalf as the Collateral
Agent hereunder and under the other Loan Documents and authorizes the Collateral Agent to take such actions on its behalf and to exercise such powers as are delegated to the Collateral Agent by the terms hereof or thereof, together with such actions
and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Administrative Agent, the Collateral Agent, the Arrangers, the Lenders and the L/C Issuers, and none of the Borrowers or any other Loan
Party shall have rights as a third party beneficiary of any of such provisions. 

  
 131 

 Each L/C Issuer shall act on behalf of the Revolving Lenders with respect to any Letters of
Credit issued by it and the documents associated therewith, and each L/C Issuer shall have all of the benefits and immunities (a) provided to the Agents in this Article with respect to any acts taken or omissions suffered by such L/C Issuer in
connection with Letters of Credit issued by it or proposed to be issued by it and L/C Documents pertaining to such Letters of Credit as fully as if the term “Agent” as used in this Article and the definition of “Agent Related
Person” included such L/C Issuer with respect to such acts or omissions, and (b) as additionally provided herein with respect to each L/C Issuer. 

Section 9.02 Rights as a Lender. Each Person serving as an Agent or an Arranger hereunder shall have
the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not an Agent or an Arranger, as applicable, and the term “Lender” or “Lenders” shall, unless otherwise
expressly indicated or unless the context otherwise requires, include the Person serving as an Agent or an Arranger, as applicable, hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own
securities of, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with any Borrower or any Subsidiary or other Affiliate thereof as if such Person were not an Agent or an Arranger, as
applicable, hereunder and without any duty to account therefor to the Lenders. 
 Section 9.03 Exculpatory
Provisions. Each Agent and each Arranger, each in its capacity as such, shall not have any obligations, duties or responsibilities under this Agreement but shall be entitled to all benefits of this Article IX. The
Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, none of the Agents or any Arranger: 

(i) shall be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing; 

(ii) shall have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers
expressly contemplated hereby or by the other Loan Documents that such Agent is required to exercise as directed in writing by the Required Lenders (or such other number of percentage of the Lenders as shall be expressly provided for herein or in
the other Loan Documents); provided that such Agent shall not be required to take any action that, in its judgment or the judgment of its counsel, may expose such Agent to liability or that is contrary to any Loan Document or applicable Law,
including for the avoidance of doubt any action that may be in violation of the automatic stay under any Bankruptcy Law or that may affect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Bankruptcy
Law; and 
 (iii) shall, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be
liable for the failure to disclose, any information relating to any Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as such Agent or any of its Affiliates in any capacity. 

No Agent shall be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such
other number or percentage of the Lenders as shall be necessary, or as such Agent shall believe in good faith shall be necessary, under the circumstances as provided in Article VIII and
Section 10.01) or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and non-appealable judgment.
No Agent shall be deemed to have knowledge or notice of the occurrence of any Default unless and until notice describing such Default is given to such Agent by MKS, a Lender or an L/C Issuer and stating that such notice is a “notice of
default.” 

  
 132 

 No Agent shall be responsible for or have any duty to ascertain or inquire into (i) any
statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or
therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness
of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items
expressly required to be delivered to such Agent. Without limiting the generality of the foregoing, the use of the term “agent” in this Agreement with reference to the Administrative Agent or the Collateral Agent is not intended to connote
any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term us used merely as a matter of market custom and is intended to create or reflect only an administrative relationship
between independent contracting parties. 
 Each party to this Agreement acknowledges and agrees that the Administrative Agent will use an
outside service provider for the tracking of all UCC financing statements required to be filed pursuant to the Loan Documents and notification to the Administrative Agent, of, among other things, the upcoming lapse or expiration thereof. No Agent
shall be liable for any action taken or not taken by such service provider. 
 Section 9.04 Reliance by
Agents. Each Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or
intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. Each Agent also may rely upon any statement made to it orally or by telephone and believed by
it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be
fulfilled to the satisfaction of a Lender or an L/C Issuer, the Administrative Agent may presume that such condition is satisfactory to such Lender or L/C Issuer unless the Administrative Agent shall have received notice to the contrary from such
Lender or such L/C Issuer prior to the making of such Loan or the issuance of such Letter of Credit. Each Agent may consult with legal counsel (who may be counsel for any Borrower), independent accountants and other experts selected by it, and shall
not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. 

Section 9.05 Delegation of Duties. Each Agent may perform any and all of its duties and exercise its
rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such
sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of
the credit facilities provided for herein as well as activities as Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the
extent that a court of competent jurisdiction determines in a final and non-appealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub-agents. 
 Section 9.06 Indemnification of Agents. Whether or
not the transactions contemplated hereby are consummated, each Lender shall indemnify upon demand each Agent Related Person and L/C Issuer (to the extent not reimbursed by or on behalf of the Borrowers and without limiting the obligations of any
Loan Party to do so) on a pro rata basis (determined as of the time that the 

  
 133 

 
applicable payment is sought based on each Lender’s ratable share at such time) and hold harmless each Agent Related Person and L/C Issuer against any and all Indemnified Liabilities
incurred by it; provided that no Lender shall be liable for payment to any Agent Related Person or L/C Issuer of any portion of such Indemnified Liabilities to the extent determined in a final,
non-appealable judgment of a court of competent jurisdiction to have resulted from such Agent Related Person’s own gross negligence or willful misconduct (and no action taken in accordance with the
directions of the Required Lenders shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section). In the case of any investigation, litigation or proceeding giving rise to any Indemnified Liabilities, this
Section applies whether any such investigation, litigation or proceeding is brought by any Lender or any other Person. Without limitation of the foregoing, each Lender shall reimburse the Administrative Agent upon demand for its ratable share of any
costs or out-of-pocket expenses (including the fees, disbursements and other charges of counsel) incurred by the Administrative Agent in connection with preparation,
execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights and responsibilities under, this Agreement, any other Loan Document,
or any document contemplated by or referred to herein, to the extent that the Administrative Agent is not reimbursed for such costs or expenses by or on behalf of the Borrowers. 

Section 9.07 Resignation of Agents. Each Agent may at any time give notice of its resignation to the
Lenders, the L/C Issuers and any Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, with, so long as no Event of Default has occurred or is continuing, the consent of the Borrowers (such consent not
to be unreasonably withheld or delayed), to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by
the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Agent gives notice of its resignation, then the retiring Agent may on behalf of the Lenders and the L/C Issuers, with, so long as no Event
of Default has occurred or is continuing, the consent of the Borrowers (such consent not to be unreasonably withheld or delayed), appoint a successor Agent meeting the qualifications set forth above; provided that if the Agent shall notify
MKS and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (a) the retiring Agent shall be discharged from its duties and obligations
hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Collateral Agent on behalf of the Lenders or the L/C Issuers under any of the Loan Documents, the retiring Collateral Agent shall continue
to hold as nominee such collateral security until such time as a successor Collateral Agent is appointed) and (b) all payments, communications and determinations provided to be made by, to or through an Agent shall instead be made by or to each
Lender and L/C Issuer directly, until such time as the Required Lenders appoint a successor Agent as provided for above in this Section 9.07. Upon the acceptance of a successor’s appointment as Agent hereunder, such
successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) (and for the avoidance of doubt, any successor Collateral Agent shall be deemed to have actual knowledge of any Swap
Agreements outstanding at such time), Agent, and the retiring Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this
Section 9.07). The fees payable by the Borrowers to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrowers and such successor. After the retiring Agent’s
resignation hereunder and under the other Loan Documents, the provisions of this Article and Section 10.04 shall continue in effect for the benefit of such retiring Agent, its
sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Agent was acting as Agent. 

  
 134 

 Any resignation by Barclays as Administrative Agent pursuant to this
Section 9.07 shall also constitute its resignation as an L/C Issuer. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, (i) such successor shall succeed to and become vested with
all of the rights, powers, privileges and duties of a retiring L/C Issuer, (ii) a retiring L/C Issuer shall be discharged from all of their respective duties and obligations hereunder or under the other Loan Documents, and (iii) the
successor L/C Issuer shall issue letters of credit in substitution for the Letters of Credit issued by the retiring L/C Issuer, if any, outstanding at the time of such succession or make other arrangements satisfactory to the retiring L/C Issuer to
effectively assume the obligations of the retiring L/C Issuer with respect to such Letters of Credit. 

Section 9.08 Non-Reliance on Agents and Other Lenders. Each
Lender and L/C Issuer acknowledges that it has, independently and without reliance upon any Agent Related Person or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement. Each Lender Party further represents and warrants that it has reviewed each document made available to it on the Platform in connection with this Agreement and has acknowledged and
accepted the terms and conditions applicable to the recipients thereof and each Lender Party also acknowledges that it will, independently and without reliance upon any Agent or any other Lender or any of their Related Parties and based on such
documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document
furnished hereunder or thereunder. 
 Section 9.09 No Other Duties, etc. Anything herein to the
contrary notwithstanding, none of the Agents or any Arranger shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent, the
Collateral Agent, a Lender or L/C Issuer hereunder. 
 Section 9.10 Administrative Agent May File Proofs of
Claim. In case of the pendency of any receivership, insolvency, examinership, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to any Loan Party, the Administrative Agent
(irrespective of whether the principal of any Loan or L/C Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on any Borrower)
shall be entitled and empowered, by intervention in such proceeding or otherwise: 
 (i) to file and prove a claim for the whole amount of
the principal and interest owing and unpaid in respect of the Loans, L/C Obligations and all other Senior Credit Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of
the Lenders, the L/C Issuers and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the L/C Issuers and the Administrative Agent and their respective agents and counsel
and all other amounts due the Lenders, the L/C Issuers and the Administrative Agent under Section 2.09 and 10.04) allowed in such judicial proceeding; 

(ii) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same; and 

(iii) and any custodian, receiver, examiner, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Lender and L/C Issuer to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders and the L/C Issuers,
to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under
Section 2.09 and 10.04. 

  
 135 

 Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize
or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Senior Credit Obligations or the rights of any Lender or to authorize the Administrative Agent to vote in
respect of the claim of any Lender in any such proceeding. 
 Section 9.11 Collateral and Guaranty
Matters. Each Lender agrees that any action taken by the Administrative Agent, the Collateral Agent or the Required Lenders (or, where required by the express terms of this Agreement, a greater or lesser proportion of the Lenders) in
accordance with the provisions of this Agreement or of the other Loan Documents, and the exercise by the Administrative Agent, the Collateral Agent or Required Lenders (or, where so required, such greater or lesser proportion) of the powers set
forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all of the Lenders. Without limiting the generality of the foregoing, the Lenders irrevocably authorize the
Administrative Agent and Collateral Agent, at its option and in its discretion: 
 (i) to release any Lien on any property granted to or
held by the Administrative Agent and Collateral Agent under any Finance Document (A) upon Discharge of Senior Credit Obligations, (B) that is sold, transferred, disposed or to be sold, transferred, disposed as part of or in connection with
any Disposition (other than any sale to a Loan Party) permitted hereunder, (C) subject to Section 10.01, if approved, authorized or ratified in writing by the Required Lenders or (D) to the extent such property is
owned by a Guarantor upon the release of such Guarantor from its obligations under its Guaranty pursuant to clause (iii) below; 

(ii) to subordinate any Lien on any property granted to or held by the Administrative Agent or the Collateral Agent under any Loan Document to
the holder of any Lien on such property that is permitted by clause (c) or (d) of the definition of Permitted Encumbrances or Section 7.02 (e), (j), (m), (p), and
(q)(iii); 
 (iii) to release any Guarantor from its obligations under the Guaranty Agreement if such Person ceases to be a
Restricted Subsidiary or becomes an Excluded Subsidiary or an Excluded Tax Subsidiary as a result of a transaction or occurrence permitted hereunder (or designation as an Unrestricted Subsidiary in accordance with
Section 6.10); provided that no such release shall occur if such Guarantor continues to be a guarantor in respect of the Term Facility, any Credit Agreement Refinancing Indebtedness (under and as defined in the Term
Credit Agreement), or any Refinanced Debt; and 
 (iv) to enter into non-disturbance and similar
agreements in connection with the licensing of intellectual property permitted pursuant to the terms of this Agreement. 
 Upon request by
the Administrative Agent at any time the Required Lenders will confirm in writing the Administrative Agent’s authority to release or subordinate its interest in particular types or items of property, or to release any Guarantor from its
obligations under the Guaranty Agreement pursuant to this Section 9.11. 

  
 136 

 In each case as specified in this Section 9.11, the applicable
Agent shall (and each Lender irrevocably authorizes the applicable Agent to), at the Borrowers’ expense, execute and deliver to the applicable Loan Party such documents as such Loan Party may reasonably request (i) to evidence the release
or subordination of such item of Collateral from the assignment and security interest granted under the Collateral Documents, (ii) to enter into non-disturbance or similar agreements in connection with
the licensing of intellectual property or (iii) to evidence the release of such Guarantor from its obligations under the Guaranty, in each case in accordance with the terms of the Loan Documents and this Section 9.11
and in form and substance reasonably acceptable to such Agent. 
 The Administrative Agent is authorized to enter into the Intercreditor
Agreement and any Other Intercreditor Agreement, intercreditor agreement, collateral trust or similar agreement contemplated hereby with respect to any (a) Indebtedness (i) that is (A) required or permitted to be subordinated
hereunder and/or (B) secured by Liens ranking senior, pari passu or junior to the Liens securing the Finance Obligations and which contemplates an intercreditor, subordination or collateral trust agreement and/or (b) obligations under any
Secured Cash Management Agreement or Secured Swap Agreement, whether or not constituting Indebtedness (any such other intercreditor agreement, an “Additional Agreement”) and the Finance Parties party hereto acknowledge that the
Intercreditor Agreement and any Additional Agreement is binding upon them. Each Finance Party party hereto (a) agrees that it will be bound by, and will not take any action contrary to, the provisions of the Intercreditor Agreement and/or any
Additional Agreement and (b) authorizes and instructs the Administrative Agent to enter into the Intercreditor Agreement and/or any Additional Agreement and to subject the Liens on the Collateral securing the Finance Obligations to the
provisions thereof. The foregoing provisions are intended as an inducement to the Finance Parties to extend credit to the Borrowers, and the Finance Parties are intended third-party beneficiaries of such provisions and the provisions of the
Intercreditor Agreement and/or any Additional Agreement. 
 Section 9.12 Related Obligations. The
benefit of the Loan Documents and of the provisions of this Agreement relating to the Collateral shall extend to and be available in respect of any Swap Obligations and Cash Management Obligations permitted hereunder from time to time owing to one
or more Affiliates of one or more Lenders or owing to one or more Swap Creditors or Cash Management Banks (collectively, “Related Obligations”) solely on the condition and understanding, as among the Collateral Agent and all Finance
Parties, that (i) the Related Obligations shall be entitled to the benefit of the Loan Documents and the Collateral to the extent expressly set forth in this Agreement and the other Loan Documents and to such extent the Administrative Agent and
the Collateral Agent shall hold, and have the right and power to act with respect to, the Guaranty Agreement and the Collateral on behalf of and as agent for the holders of the Related Obligations, but the Administrative Agent and the Collateral
Agent are otherwise acting solely as agent for the Lenders and the L/C Issuers and shall have no fiduciary duty, duty of loyalty, duty of care, duty of disclosure or other obligation whatsoever to any holder of Related Obligations, (ii) all
matters, acts and omissions relating in any manner to the Guaranty Agreement, the Collateral, or the omission, creation, perfection, priority, abandonment or release of any Lien, shall be governed solely by the provisions of this Agreement and the
other Loan Documents and no separate Lien, right, power or remedy shall arise or exist in favor of any Finance Party under any separate instrument or agreement or in respect of any Related Obligation, (iii) each Finance Party shall be bound by
all actions taken or omitted, in accordance with the provisions of this Agreement and the other Loan Documents, by the Administrative Agent, the Collateral Agent and the Required Lenders, as applicable, each of whom shall be entitled to act at its
sole discretion and exclusively in its own interest given its own Commitments and its own interest in the Loans, the L/C Obligations and other Senior Credit Obligations to it arising under this Agreement or the other Loan Documents, without any duty
or liability to any Swap Creditor or Cash Management Bank or as to any Related Obligation and without regard to whether any Related Obligation remains outstanding or is deprived of the benefit of the Collateral or becomes unsecured or is otherwise
affected or put in jeopardy thereby and (iv) no holder of Related Obligations and no other Finance Party (except the Lenders to the extent set forth in this Agreement) shall have any right to be notified of, or to direct, require or be heard
with respect to, or to consent to, any action taken or omitted in respect of the Collateral or under this Agreement or the Loan Documents. 

  
 137 

 Section 9.13 Withholding Tax. To the extent required
by any applicable law, the Administrative Agent may deduct or withhold from any payment to any Lender Party an amount equivalent to any applicable withholding Tax. Without limiting or expanding the provisions of
Section 3.01, each Lender Party shall indemnify and hold harmless the Administrative Agent against, within ten (10) days after written demand therefor, any and all Taxes and any and all related losses, claims,
liabilities and expenses (including fees, charges, and disbursements of any counsel for the Administrative Agent) incurred by or asserted against the Administrative Agent by the Internal Revenue Service or any other Governmental Authority as a
result of the failure of the Administrative Agent to properly withhold Tax from amounts paid to or for the account of such Lender Party for any reason (including, without limitation, because the appropriate form was not delivered or not properly
executed, or because such Lender Party failed to notify the Administrative Agent of a change in circumstances that rendered the exemption from, or reduction of, withholding Tax ineffective, whether or not such Tax was correctly or legally imposed or
asserted by the relevant Governmental Authority). A certificate as to the amount of such payment or liability delivered to any Lender Party by the Administrative Agent shall be conclusive absent manifest error. Each Lender Party hereby authorizes
the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender Party under this Agreement or any other Loan Document against any amount due to the Administrative Agent by such Lender under this
Section 9.13. The agreements in this Section 9.13 shall survive the resignation and/or replacement of the Administrative Agent, any assignment of rights by, or the replacement of, a Lender Party,
the termination of the Agreement or Commitments and the repayment, satisfaction or discharge of all other obligations. 

Section 9.14 Certain ERISA Matters. 

(a) Each Lender (x) represents and warrants, as of the date such Person became a Lender party hereto, to, and (y) covenants, from the
date such Person became a Lender party hereto to the date such Person ceases being a Lender party hereto, for the benefit of, the Administrative Agent and not, for the avoidance of doubt, to or for the benefit of the Borrower or any other Loan
Party, that at least one of the following is and will be true: 
 (i) such Lender is not using “plan assets” (within the meaning
of Section 3(42) of ERISA or otherwise) of one or more Benefit Plans with respect to such Lender’s entrance into, participation in, administration of and performance of the Revolving Loans, the Letters of Credit, the Commitments or this
Agreement, 
 (ii) the transaction exemption set forth in one or more PTEs, such as PTE 84-14

transactions involving bank collective investment funds) or PTE 96-23 (a class exemption for certain transactions determined by in-house asset managers), is
applicable with respect to such Lender’s entrance into, participation in, administration of and performance of the Revolving Loans, the Letters of Credit, the Revolving Commitments and this Agreement, 

(iii) (A) such Lender is an investment fund managed by a “Qualified Professional Asset Manager” (within the meaning of Part VI of PTE 84-14), (B) such Qualified Professional Asset Manager made the investment decision on behalf of such Lender to enter into, participate in, administer and perform the Revolving Loans, the Letters of
Credit, the Revolving 

  
 138 

 
Commitments and this Agreement, (C) the entrance into, participation in, administration of and performance of the Revolving Loans, the Letters of Credit, the Revolving Commitments and this
Agreement satisfies the requirements of sub-sections (b) through (g) of Part I of PTE 84-14 and (D) to the best knowledge of such Lender, the
requirements of subsection (a) of Part I of PTE 84-14 are satisfied with respect to such Lender’s entrance into, participation in, administration of and performance of the Revolving Loans, the
Letters of Credit, the Revolving Commitments and this Agreement, or 
 (iv) such other representation, warranty and covenant as may be
agreed in writing between the Administrative Agent, in its sole discretion, and such Lender. 
 (b) In addition, unless either (1) sub-clause (i) in the immediately preceding clause (a) is true with respect to a Lender or (2) a Lender has provided another representation, warranty and covenant in accordance with sub-clause (iv) in the immediately preceding clause (a), such Lender further (x) represents and warrants, as of the date such Person became a Lender party hereto, to, and (y) covenants, from the
date such Person became a Lender party hereto to the date such Person ceases being a Lender party hereto, for the benefit of, the Administrative Agent and not, for the avoidance of doubt, to or for the benefit of the Borrowers or any other Loan
Party, that the Administrative Agent is not a fiduciary with respect to the assets of such Lender involved in such Lender’s entrance into, participation in, administration of and performance of the Revolving Loans, the Letters of Credit, the
Commitments and this Agreement (including in connection with the reservation or exercise of any rights by the Administrative Agent under this Agreement, any Loan Document or any documents related to hereto or thereto).

(a) Amendments Generally. Except as otherwise set forth in this Agreement, no amendment or waiver of any provision of this
Agreement or any other Loan Document, and no consent to any departure by any Loan Party therefrom, shall in any event be effective unless the same shall be in writing signed by the Required Lenders (or by the Administrative Agent with the consent of
the Required Lenders or such other number or percentage of the Lenders as may be specified herein) and the Borrowers, and each such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given;
provided that the Administrative Agent and the Borrowers may, without the consent of the other Lenders, amend, modify or supplement this Agreement and any other Loan Document in order (i) to comply with local Law or advice of local
counsel, (ii) to cure ambiguities or defects or (iii) to cause any such Loan Document to be consistent with this Agreement and the other Loan Documents; and provided further that if the Administrative Agent and the Borrowers

of this Agreement or any other Loan Document (including, for the avoidance of doubt, any exhibit, schedule or other attachment to any Loan Document), then the Administrative Agent (acting in its sole discretion) and the Borrowers or any other
relevant Loan Party shall be permitted to amend such provision and such amendment shall become effective without any further action or consent of any other party to any Loan Document.

amendment, waiver or consent shall: 

  
 139 

 (i) extend or increase the Commitment of any Lender without the written consent of such
Lender (it being understood that a waiver of any condition precedent set forth in Section 4.02 or the waiver of any Default, mandatory prepayment or mandatory reduction of any Commitments shall not constitute an extension
or increase of any Commitment of any Lender); 
 (ii) postpone any date fixed by this Agreement or any other Loan Document for any payment
(excluding mandatory prepayments) of principal, interest (other than Default interest), fees or other amounts due to the Lenders (or any of them) hereunder or under any other Loan Document without the written consent of each Lender directly affected
thereby;

will be required to amend the definition of “Default Rate”; 
 (iv) other than to the extent required to make the Lenders share in
pro rata payments after giving effect to the implementation of an Incremental Facility, change Section 2.12, Section 2.13 or Section 8.03 in a manner that would alter the

Section 7.03 or released in compliance with Section 9.11) or (b) release any Borrower from the Guaranty Agreement without the written consent of each Lender;

Section 7.03, sold or transferred pursuant to a Permitted Restructuring Transaction or released in compliance with Section 9.11); 

(x) modify the definition of Alternative Currency (except as set forth in Section 1.08) without the consent of each

prior written consent of the Administrative Agent; and 

  
 140

impair the ability of the Administrative Agent to add, remove, reduce or increase reserves included in the Borrowing Base in its Permitted Discretion), or any of the component definitions thereof which result in increased Excess Availability without
the written consent of the Supermajority Lenders. 
 Notwithstanding anything to the contrary contained in this
Section 10.01, this Agreement and the other Loan Documents may be amended, modified or supplemented with the consent of the Administrative Agent and/or the Collateral Agent at the request of the Borrowers without the need
to obtain the consent of any other Lender if such amendment is delivered in order to effectuate any amendment, modification or supplement pursuant to the proviso of Section 10.01(a). 

Each Lender and each holder of a Revolving Note shall be bound by any waiver, amendment or modification authorized by this
Section 10.01 regardless of whether its Revolving Note shall have been marked to make reference therein, and any consent by any Lender or holder of a Revolving Note pursuant to this Section 10.01
shall bind any Person subsequently acquiring a Revolving Note from it, whether or not such Revolving Note shall have been so marked.

Term Facility or any Permitted Refinancing Indebtedness in respect thereof, in each case, as parties thereto, as expressly contemplated by the terms of the Intercreditor Agreement or such Other Intercreditor Agreement (it being understood that any
such amendment or supplement may make such other changes to the applicable intercreditor agreement as, in the good faith determination of the Administrative Agent, are required to effectuate the foregoing and provided, that such other changes are
not adverse, in any material respect, to the interests of the Lenders) or (ii) that is expressly contemplated by the Intercreditor Agreement (or the comparable provisions, if any of any Other Intercreditor Agreement).

electronic communications pursuant to procedures approved by it (including as set forth in Section 10.02(d)); provided that approval of such procedures may be limited to particular notices or communications.

 (d) Posting. Each Loan Party hereby agrees that it will provide to the
Administrative Agent all information, documents and other materials that it is obligated to furnish to the Administrative Agent pursuant to this Agreement and any other Loan Document, including all notices, requests, financial statements, financial
and other reports, certificates and other information materials, but excluding any such communication that (i) relates to a request for a new, or a conversion of an existing, Revolving Borrowing or other extension of credit (including any

the Administrative Agent at agency.transactions@db.com or at such other e-mail address(es) provided to MKS from time to time or in such other form, including hard copy delivery thereof, as the
Administrative Agent shall require. In addition, each Loan Party agrees to continue to provide the Communications to the Administrative Agent in the manner specified in this Agreement or any other Loan Document or in such other form, including hard
copy delivery thereof, as the Administrative Agent shall require. Nothing in this Section 10.02 shall prejudice the right of the Agents, any Lender or any Loan Party to give any notice or other communication pursuant to
this Agreement or any other Loan Document in any other manner specified in this Agreement or any other Loan Document or as any such Agent shall require. Excluded Communications shall be delivered to the Administrative Agent by facsimile
communication or as the Administrative Agent shall direct. 
 The Communications required to be delivered pursuant to
Section 6.01 may be delivered electronically and if so delivered, shall be deemed to have been delivered on the date (i), in the case of financial statements and Communications referred to in
Sections 6.01(a) and (b) and Section 6.02 on which such financial statements and/or appropriate disclosures are publicly available as posted on the Electronic Data Gathering, Analysis
and Retrieval system (EDGAR) or any successor filing system of the SEC, (ii) MKS posts such documents, or provides a link thereto on MKS’s website on the Internet; or (iii) on which such documents are posted on MKS’s behalf
on an Internet or Intranet website, if any, to which the Administrative Agent has access (whether a commercial, third-party website or whether sponsored by the Administrative Agent); provided that: (i) upon written request by the
Administrative Agent, MKS shall deliver copies (which may be electronic) of such documents to the Administrative Agent until a written request to cease delivering copies is given by the Administrative Agent and (ii) MKS shall notify (which may
be by facsimile or electronic mail) the Administrative Agent (and each Lender if there is at the time no incumbent Administrative Agent) of the posting of any such documents and provide to the Administrative Agent by electronic mail electronic
versions (i.e. soft copies) of such documents. The Administrative Agent shall have no obligation to request the delivery or to maintain copies of the documents referred to above, and in any event shall have no responsibility to monitor compliance by
any Borrower with any such request for delivery, and each Lender shall be solely responsible for requesting delivery to it or maintaining its copies of such documents. Furthermore, if any financial statement, certificate or other information
required to be delivered pursuant to Section 6.01 shall be required to be delivered on any date that is not a Business Day, such financial statement, certificate or other information may be delivered to the Administrative
Agent on the next succeeding Business Day after such date. 
 To the extent consented to by the Administrative Agent in writing from time to
time, the Administrative Agent agrees that receipt of the Communications by the Administrative Agent at its e-mail address(es) set forth above shall constitute effective delivery of the Communications to the
Administrative Agent for purposes of the Loan Documents; provided that MKS shall also deliver to the Administrative Agent an executed original of each Compliance Certificate required to be delivered hereunder. 

  
 144 

 Each Loan Party further agrees that the Administrative Agent may make the Communications
available to the Lenders by posting the Communications on a Platform. The Platform is provided “as is” and “as available.” The Agents do not warrant the accuracy or completeness of the Communications, or the adequacy of the
Platform and expressly disclaim liability for errors or omissions in the Communications. No warranty of any kind, express, implied or statutory, including, without limitation, any warranty of merchantability, fitness for a particular purpose, non-infringement of third party rights or freedom from viruses or other code defects, is made by any Agent in connection with the Communications or the Platform. In no event shall the Administrative Agent or any of
its Related Parties have any liability to the Loan Parties, any Lender, any L/C Issuer or any other Person for damages of any kind, including direct or indirect, losses or expenses (whether in tort, contract or otherwise) arising out of any Loan
Party’s or the Administrative Agent’s transmission of communications through the Internet, except to the extent the liability of such Person is found in a final non-appealable judgment by a court of
competent jurisdiction to have resulted from such Person’s gross negligence, bad faith or willful misconduct. Additionally, in no event shall the Administrative Agent or any of its Related Parties have any liability to the Loan Parties, any
Lender, any L/C Issuer or any other Person for any special, incidental or consequential damages. 
 Each Borrower hereby acknowledges that
(i) the Administrative Agent and/or the Arrangers will make available to the Lenders and the L/C Issuers materials and/or information provided by or on behalf of any Borrower hereunder (collectively, “Borrower Materials”) by
posting the Borrower Materials on IntraLinks or another similar electronic system (the “Platform”) and (ii) certain of the Lenders may be “public-side” Lenders (i.e., Lenders that do not wish to receive material non-public information with respect to the Borrowers or its Affiliates, or the respective securities of any of the foregoing) (each, a “Public Lender”). So long as any Borrower is the issuer of any
outstanding debt or equity securities that are issued pursuant to a public offering registered with the SEC or in a private placement for resale pursuant to Rule 144A under the Securities Act, or is actively contemplating issuing any such
securities: (i) Borrower Materials shall not be made available to Public Lenders unless clearly and conspicuously marked “Public – Does Not Contain Non-Public Information” which, at a
minimum, shall mean that the words “Public – Does Not Contain Non-Public Information” shall appear prominently on the first page thereof; (ii) by not marking Borrower Materials “Public
– Does Not Contain Non-Public Information,” such Borrower shall be deemed to have notified the Administrative Agent, the Arrangers, the L/C Issuers and the Lenders to treat such Borrower Materials as
containing material non-public information with respect to any Borrower or its or their securities for purposes of United States Federal and state securities laws; (iii) all Borrower Materials that are
marked “Public – Does Not Contain Non-Public Information” are permitted to be made available through a portion of the Platform designated “Public Investor,” (provided,
however, that to the extent such Borrower Materials constitute Information, they shall be treated as set forth in Section 10.07); and (iv) the Administrative Agent and the Arrangers shall treat only any Borrower
Materials that are marked “Public – Does Not Contain Non-Public Information” as being suitable for posting on a portion of the Platform designated “Public Investor.” 

Section 10.03 No Waiver; Cumulative Remedies. No failure by any Lender or any L/C Issuer or by the
Administrative Agent to exercise, and no delay by any such Person in exercising, any right, remedy, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege
hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and
privileges provided by Law.

 Section 10.04 Expenses; Indemnity; Damage Waiver.

necessary) in connection with the syndication and closing of the Loans provided for herein, the preparation, negotiation, execution, and delivery of this Agreement and the other Loan Documents or, with respect to the Administrative Agent and
Collateral Agent, any administration, amendment, amendment and restatement, modification or waiver of the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), including in connection
with post-closing searches to confirm that security filings and recordations have been properly made and including any costs and expenses of the service provider referred to in Section 9.03 and in connection with its the
protection of its rights and remedies (A) in connection with this Agreement and the other Loan Documents, including its rights under this Section 10.04, or (B) in connection with the Loans made hereunder,
including all such reasonable out-of-pocket expenses incurred during any legal proceeding, including any Insolvency or Liquidation Proceeding, and including in
connection with any workout, restructuring or negotiations in respect of such Loans or Letters of Credit, (ii) all reasonable and documented out of pocket expenses incurred by any L/C Issuer in connection with the issuance, amendment, renewal
or extension of any Letter of Credit or any demand for payment thereunder, and (iii) all reasonable and documented out of pocket expenses incurred by the Administrative Agent, the Collateral Agent, any Lender or any L/C Issuer (including the
reasonable and documented fees, charges and disbursements of counsel for the Administrative Agent, the Collateral Agent, any Lender or any L/C Issuer), in connection with the enforcement or protection of its rights and remedies (A) in
connection with this Agreement and the other Loan Documents, including its rights under this Section 10.04, or (B) in connection with the Loans made or Letters of Credit issued hereunder, including all such reasonable
and documented out-of-pocket expenses incurred during any legal proceeding, including any proceeding under any Bankruptcy Law, and including in connection with any
workout, restructuring or negotiations in respect of such Loans or Letters of Credit; provided, however, that the Borrowers will not be required to pay the fees and expenses of more than one lead counsel to the Administrative Agent,
the Collateral Agent, any Lender or any L/C Issuer (plus one local counsel in each applicable local jurisdiction and one specialty counsel in each applicable specialty) and, in the case of an actual or potential conflict of interest, one
additional counsel per affected party in connection with the enforcement or protection of its rights and remedies. 
 (b)
Indemnification by Borrowers. The Loan Parties, jointly and severally, shall indemnify the Administrative Agent (and any sub-agent thereof), the Collateral Agent (and any sub-agent thereof), the Arrangers, each Lender and each L/C Issuer, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each
Indemnitee harmless from, any and all liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs (including settlement costs), disbursements and out-of-pocket fees and expenses (including the fees, charges and disbursements of counsel) incurred by any Indemnitee or asserted against any Indemnitee by any third party or by any Borrower or any other Loan
Party arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan Document, or any amendment, amendment and restatement, modification or waiver of the provisions hereof or thereof, or
any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder or the consummation of the transactions contemplated hereby, thereby, or related thereto or, in
the case of the Administrative Agent (and any sub-agent thereof) and its Related Parties only, the administration of this Agreement and the other Loan Documents, (ii) any Loan or Letter of Credit or the
use or proposed use of the proceeds therefrom (including any refusal by any L/C Issuer to honor a demand for payment under a Letter of Credit if the 

  
 146 

 
documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or Release or threatened Release of
Hazardous Materials on, at, under or from any property owned, leased or operated by any Borrower or any of its Restricted Subsidiaries at any time, or any Environmental Liability related in any way to any Borrower or any of its Restricted
Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by a Borrower or any other
Loan Party, and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are
determined by a court of competent jurisdiction by final and non-appealable judgment to have resulted from the gross negligence, bad faith, material breach or willful misconduct of such Indemnitee or a Related
Party thereof, or (y) disputes solely among Indemnitees not involving any act or omission of any Loan Party or any of their respective Related Parties (other than a dispute against the Administrative Agent, Collateral Agent or any Arranger in
their capacities as such); provided, further, that the Loan Parties shall not be required to reimburse the legal fees and expenses of more than one counsel (in addition to one special counsel in each specialty area, up to one local
counsel in each applicable local jurisdiction and any additional counsel for an Indemnified Party reasonably deemed appropriate by virtue of potential conflicts of interests incurred in connection with investigating, defending or preparing to defend
any such action, suit, proceeding (including any inquiry or investigation) or claim (whether or not any Agent, any Lender or any other such Indemnified Party is a party to any action or proceeding out of which any such expenses arise)). This
Section 10.04(b) shall not apply with respect to Taxes other than any Taxes that represent losses, claims, damages, or liabilities arising from any non-Tax claim. 

(c) Waiver of Consequential Damages, Etc. To the full extent permitted by applicable Law, no Loan Party shall assert, and each
Loan Party hereby waives, any claim against any Indemnitee, and each of the Agents, each L/C Issuer and each Lender agrees not to assert or permit any of their respective Subsidiaries to assert any claim against any Borrower or any of its
Subsidiaries or any of their respective directors, officers, employees, attorneys, agents or advisors, on any theory of liability, for special, indirect, consequential (including, without limitation, any loss of profits, business or anticipated
savings) or punitive damages (in each case, as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions
contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof (for the avoidance of doubt, nothing in this Section 10.04(c) shall limit any Indemnitee’s right to indemnification
provisions for third party claims as set forth in Section 10.04(b)). No Indemnitee referred to in clause (b) above shall be liable for any damages arising from the use by unintended recipients of
any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby,
except to the extent the liability of such Indemnitee is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnitee’s gross negligence, bad faith
or willful misconduct. 
 (d) Payments. All amounts due under this Section shall be payable not later than thirty
(30) days after receipt of invoice in reasonable detail of such amounts. 
 (e) Survival. The agreements in this Section
shall survive the resignation of the Administrative Agent or L/C Issuer, the replacement of any Lender Party, the termination of the Commitments and the repayment, satisfaction or discharge of all the other Senior Credit Obligations. 

  
 147 

 Section 10.05 Payments Set Aside. To the extent
permitted by applicable law, to the extent that any payment by or on behalf of a Borrower or any other Loan Party is made to the Administrative Agent or any Lender, or the Administrative Agent or any Lender exercises its right of setoff, and such
payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Administrative Agent or such Lender in
its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Insolvency or Liquidation Proceeding or otherwise, then (i) to the extent of such recovery, the obligation or part thereof
originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred, and (ii) each Lender severally agrees to pay to the Administrative Agent upon
demand its applicable share of any amount so recovered from or repaid by the Administrative Agent, plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the Overnight Rate from time
to time in effect. The obligations of the Lender Parties under clause (ii) of the preceding sentence shall survive the payment in full of the Senior Credit Obligations and the termination of this Agreement. 

Section 10.06 Successors and Assigns. 

(a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns permitted hereby, except that no Borrower may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each
Lender Party (provided that a Borrower (other than MKS) may assign or otherwise transfer its rights or obligations hereunder to MKS in connection with a transaction permitted under Section 7.03(a)(i)) and no Lender
may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of clause (b) below, (ii) by way of participation in accordance with
the provisions of clause (d) below or (iii) by way of pledge or assignment of a security interest subject to the restrictions of clause (f) below (and any other attempted assignment or
transfer by any Borrower or any Lender shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby,
Participants to the extent provided in clause (d) below and, to the extent expressly contemplated hereby, the other Indemnitees) any legal or equitable right, remedy or claim under or by reason of this Agreement. 

(b) Assignments by Lenders. Any Lender may at any time assign to one or more Eligible Assignees, all or a portion of its rights
and obligations under this Agreement, including all or a portion of its Commitments and the Loans (including for purposes of this clause (b), any participation interests in Protective Advance Exposure and any Participation
Interests in the Letters of Credit) at the time owing to it; provided, however, that: 
 (i) except in the case of an
assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount
of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the Commitments are not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment, determined as of
the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date, shall not be less than $5,000,000,
unless each of the Administrative Agent and, so long as no payment or bankruptcy Event of Default has occurred and is continuing, MKS otherwise consents (each such consent not to be unreasonably withheld or delayed; provided that, MKS shall
be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within ten (10) Business Days after MKS has received notice thereof); provided, however, that
concurrent assignments to members of an Assignee 

  
 148 

 
Group and concurrent assignments from members of an Assignee Group to a single Eligible Assignee (or to an Eligible Assignee and members of its Assignee Group) will be treated as a single
assignment for purposes of determining whether such minimum amount has been met; 
 (ii) each partial assignment shall be made as an
assignment of a proportionate part of all the assigning Lenders’ rights and obligations under this Agreement with respect to the class of Loans or the class of Commitment assigned; 

(iii) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a
processing and recordation fee in the amount of $3,500; provided, however, that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment; provided,
further, that only a single processing and recordation fee shall be payable in respect of multiple contemporaneous assignments to Approved Funds with respect to any Lender. The assignee, if it is not a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire; 
 (iv) No such assignment shall be made to any Defaulting Lender or any of its
Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (iv); and 

(v) In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective
unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate
(which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrowers and the Administrative Agent, the applicable pro rata share of
Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to
the Administrative Agent or any Lender hereunder (and interest accrued thereon) and (y) acquire (and fund as appropriate) its full pro rata share of all Loans, participation interests in Protective Advance Exposure and participations in Letters
of Credit in accordance with its Applicable Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable Law without compliance with
the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs. 

Subject to acceptance and recording thereof by the Administrative Agent pursuant to clause (c) below, from and after the effective
date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under
this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all
of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 3.01, 3.04, 3.05,
and 10.04 with respect to facts and circumstances occurring prior to the effective date of such assignment). Upon request, the Borrowers (at their expense) shall execute and deliver a Revolving Note to the assignee Lender. Any assignment
or transfer by a Lender of rights or obligations under this Agreement that does not comply with this clause (b) shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and
obligations in accordance with clause (d) below. 

  
 149 

 (c) Register. The Administrative Agent, acting solely for this purpose as a non-fiduciary agent of the Borrowers, shall maintain at the Administrative Agent’s Office a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses
of the Lenders, and the Commitments of, and principal amounts (and related interest amounts) of the Loans and L/C Obligations owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The Register shall
record each transfer of the Loans to a transferee upon written notification by the registered owner of such transfer; provided, however, that failure to make any such recordation, or any error in such recordation, shall not affect any
Lender’s Commitments in respect of any Loan. The entries in the Register shall be conclusive absent manifest error, and the Borrowers, the Administrative Agent, the L/C Issuers and the Lenders shall treat each Person whose name is recorded in
the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. In addition, the Administrative Agent shall maintain on the Register information regarding the designation,
and revocation of designation, of any Lender as a Defaulting Lender. The Register shall be available for inspection by MKS, the L/C Issuers, the Collateral Agent and, with respect to its own interest only, any other Lender, at any reasonable time
and from time to time upon reasonable prior notice. 
 (d) Participations. Any Lender may at any time, without the consent of,
or notice to, any Borrower, the L/C Issuers or the Administrative Agent sell participations to any Person (other than a natural Person, any Borrower or any of its Subsidiaries) (each, a “Participant”) in all or a portion of such
Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans (including such Lender’s participations in the Protective Advances and the L/C Obligations) owing to it);
provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the
Borrowers, the Administrative Agent and the Lender Parties shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. 

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right
to enforce the Loan Documents and to approve any amendment, modification or waiver of any provision of the Loan Documents; provided that such agreement or instrument may provide that such Lender will not, without the consent of the
Participant, agree to any amendment, modification or waiver described in clauses (i), (ii) or (iii) of Section 10.01(b) that directly affects such Participant. Subject to
clause (e) below, each Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.01 or 3.04, and 3.05 (subject to the requirements and
limitations of such Sections) to the same extent as if it were a Lender (but, with respect to any particular Participant, to no greater extent than the Lender that sold the participation to such Participant) and had acquired its interest by
assignment pursuant to clause (b) above; provided that such Participant agrees to be subject to the provisions of Section 3.07 as if it were an assignee under clause (b)
above. To the extent permitted by Law, each Participant also shall be entitled to the benefits of Section 10.08 as though it were a Lender (but, with respect to any particular Participant, to no greater extent than the
Lender that sold the participation to such Participant); provided such Participant agrees to be subject to Section 2.13 as though it were a Lender. 

Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent
of the Borrowers, maintain a register on which it enters the name and address of each Participant and the principal amounts (and related interest amounts) of each Participant’s interest in the Loans or other obligations under this Agreement
(the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any Participant or any information relating
to a Participant’s interest in any Commitments, Credit Extensions or other obligations under any Loan Document) except to the extent that such 

  
 150 

 
disclosure is necessary in connection with a Tax audit or other proceeding to establish that any such Commitment, Credit Extension or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive, absent manifest error, and such Lender shall treat each Person whose name is recorded
in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. 

No participation shall be or shall be deemed to be a discharge, rescission, extinguishment or substitution of any outstanding Loan and any
Loan subject to a participation shall continue to be the same obligation and not a new obligation. 
 (e) Limitations on Participant
Rights. A Participant shall not be entitled to receive any greater payment under Sections 3.01 or 3.04 than the applicable Lender would have been entitled to receive with respect to the participation
sold to such Participant, unless the sale of the participation to such Participant is made with MKS’s prior written consent. 
 (f)
Certain Pledges. Any Lender may at any time, without the consent of any Borrower or the Administrative Agent, pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Revolving
Note, if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank or any other central bank; provided that no such pledge or assignment shall release such Lender from any of
its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. 
 (g) Electronic Execution of
Assignments. The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form,
each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable Law, including the
Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act. 

Section 10.07 Treatment of Certain Information; Confidentiality. Each of the Agents and the Lender
Parties agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ respective partners, directors, officers, employees,
agents, advisors, managing members or managers, counsel, accountants and other representatives (collectively, “Representatives”) solely in connection with the transactions contemplated hereby (it being understood that the Persons to
whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any Governmental Authority or regulatory authority (including any
self-regulatory authority, such as the National Association of Insurance Commissioners) (in which case, the Administrative Agent or such Lender Party, as applicable, shall use reasonable efforts to notify MKS prior to such disclosure to the extent
practicable and legally permitted to do so), (c) to the extent required by applicable Laws or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or
under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) to any state, federal or foreign authority or examiner regulating any
Lender, (g) (i) any rating agency, and (ii) subject to an agreement containing provisions substantially the same as those of this Section 10.07, to (x) any assignee of or Participant in (or their
Representatives, it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information 

  
 151 

 
confidential), or any prospective assignee of or Participant in (or their Representatives, it being understood that the Persons to whom such disclosure is made will be informed of the
confidential nature of such Information and instructed to keep such Information confidential) any of its rights or obligations under this Agreement or (y) any actual or prospective counterparty (or its Representatives, it being understood that
the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential) to any swap or derivative transaction relating to any Borrower and its obligations,
(h) with the consent of MKS, (i) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section and not in breach of any agreement binding on any Person (to the knowledge of such
Person) or (y) becomes available to the Administrative Agent, any Lender Party or any of their respective Affiliates on a non-confidential basis from a source other than any Borrower or (j) to market
data collectors, similar services providers to the lending industry, loan syndication and pricing reporting services or in their marketing or promotional materials, with such information to consist of deal terms customarily found in such
publications or marketing or promotional materials and may otherwise use the name, logos, and other insignia of any Borrower or the other Loan Parties and the Commitments provided hereunder in any “tombstone”, on its website or in other
marketing materials of the Agents. For purposes of this Section, “Information” means all information received from or on behalf of MKS or any of its Subsidiaries relating to MKS or any of its Subsidiaries or any of their respective
businesses or Affiliates, other than any such information that is available to the Administrative Agent or any Lender Party on a non-confidential basis prior to disclosure by MKS or any of its Subsidiaries.
Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of
such Information as such Person would accord to its own confidential information. 
 Section 10.08 Right of
Setoff. If an Event of Default shall have occurred and be continuing, each Lender Party and each of their respective Affiliates is hereby authorized at any time and from time to time, to the full extent permitted by applicable Law, to set
off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender Party or any such Affiliate to or for
the credit or the account of any Borrower or any other Loan Party against any and all of the then due and owing obligations of such Borrower or such Loan Party, as applicable, now or hereafter existing under this Agreement or any other Loan Document
to such Lender Party, irrespective of whether or not such Lender Party shall have made any demand under this Agreement or any other Loan Document or (x) such obligations may be contingent or unmatured or (y) are owed to a branch or office
of such Lender Party different from the branch or office holding such deposit or obligated on such indebtedness; provided, that in the event that any Defaulting Lender shall exercise any such right of setoff, (x) all amounts so set off
shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 2.17 and, pending such payment, shall be segregated by such Defaulting Lender from its other
funds and deemed held in trust for the benefit of the Administrative Agent and the Lender Parties, and (y) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the Senior Credit
Obligations owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of each Lender Party and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of
setoff) that such Lender Party or their respective Affiliates may have. Each Lender Party agrees to notify MKS and the Administrative Agent promptly after any such setoff and application; provided that the failure to give such notice shall
not affect the validity of such setoff and application. 
 Section 10.09 Interest Rate Limitation.
Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by
applicable Law (the “Maximum Rate”). If the Administrative Agent or any Lender shall receive interest in an amount that exceeds the 

  
 152 

 
Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the applicable Borrower. In determining whether the interest
contracted for, charged, or received by the Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable Law, (i) characterize any payment that is not principal as an expense, fee, or premium
rather than interest, (ii) exclude voluntary prepayments and the effects thereof and (iii) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Senior Credit
Obligations hereunder. 
 Section 10.10 Counterparts; Integration; Effectiveness. This Agreement may
be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Loan
Documents, and any separate letter agreements with respect to fees payable to the Administrative Agent, constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof; provided that, notwithstanding anything contained herein, the Fee Letters shall survive the Closing Date. Except as provided in Section 4.01,
this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties
hereto. Delivery of an executed counterpart of a signature page of this Agreement by telecopier shall be effective as delivery of a manually executed counterpart of this Agreement. 

Section 10.11 Survival of Agreement. All covenants, agreements, representations and warranties made by
the Loan Parties in the Loan Documents and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and
shall survive the execution and delivery of the Loan Documents and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Agents, the
L/C Issuers or any Lender may have had notice or knowledge of any Default, Event of Default, or incorrect representation or warranty at the time of any Credit Extension, and shall continue in full force and effect until the Discharge of Senior
Credit Obligations. The provisions of Sections 2.14, 3.01, 3.04, 3.05, 10.04, and Sections 10.10 through 10.15 shall survive and remain in full force and
effect regardless of the repayment of the Loans, the payment of the Reimbursement Obligations, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof. 

Section 10.12 Severability. Any provision of this Agreement held to be invalid, illegal or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the
invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. Without limiting the foregoing provisions of this Section 10.12, if and to the extent that the
enforceability of any provisions in this Agreement relating to Defaulting Lenders shall be limited by Bankruptcy Laws, as determined in good faith by the Administrative Agent or the L/C Issuers, as applicable, then such provisions shall be deemed to
be in effect only to the extent not so limited.

Process; Waiver of Jury Trial.

controversy, dispute or cause of action (whether in contract or tort or otherwise) based upon, arising out of or relating to this Agreement or any other Loan Document (except, as to any other Loan Document, as expressly set forth therein), and the
transactions contemplated hereby and thereby shall be governed by, and construed in accordance with, the Law of the State of New York.

jurisdiction of such courts and agrees that all claims in respect of any such action, litigation or proceeding may be heard and determined in such New York State court or, to the full extent permitted by applicable Law, in such Federal court. Each
of the parties hereto agrees that a final judgment in any such action, litigation or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Nothing in this Agreement
or in any other Loan Document shall affect any right that the Administrative Agent or any Lender Party may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against any Borrower or its properties

 (c) Waiver of Venue. Each party hereby irrevocably and unconditionally waives, to the

Agent (for itself and not on behalf of any Lender) hereby notifies the Borrowers and the other Loan Parties that pursuant to the requirements of the PATRIOT Act (Title III of Pub. L. 107-56 (signed into
law October 26, 2001) (the “Patriot Act”)), it is required to obtain, verify and record information that identifies the Borrowers and the other Loan Parties, which information includes the name, address and tax identification

and any related arranging or other services in connection therewith (including in connection with any amendment, waiver or other modification hereof or of any other Loan Document) are an arm’s-length
commercial transaction between the Borrowers and their Affiliates, on the one hand, and the Administrative Agent, the Collateral Agent, the Arrangers and the Lenders, on the other hand, and each Borrower is capable of evaluating and understanding
and understands and accepts the terms, risks and conditions of the transactions contemplated hereby and by the other Loan Documents (including any amendment, waiver or other modification hereof or thereof); (ii) in connection with the process
leading to such transaction, the Administrative Agent, the Collateral Agent and the Arrangers are and have been acting solely as a principal and are not the agent or fiduciary for any Borrower or any of its Affiliates, stockholders, creditors or
employees or any other Person; (iii) neither the Administrative Agent, the Collateral Agent nor any Arranger has assumed or will assume an advisory, agency or fiduciary responsibility in favor of any Borrower with respect to any of the
transactions contemplated hereby or the process leading thereto, including with respect to any amendment, waiver or other modification hereof or of any other Loan Document (irrespective of whether the Administrative Agent, the Collateral Agent or
any Arranger has advised or is currently advising any Borrower or any of its Affiliates on other matters) and neither the Administrative Agent, the Collateral Agent nor any Arranger has any obligation to any Borrower or any of its Affiliates with
respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the other Loan Documents; (iv) the Administrative Agent, the Collateral Agent and the Arrangers and their respective Affiliates may be
engaged in a broad range of transactions that involve interests that differ from those of the Borrowers and their Affiliates, and neither the Administrative Agent, the Collateral Agent nor any Arranger has any obligation to disclose any of such
interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Administrative Agent, the Collateral Agent and the Arrangers have not provided and will not provide any legal, accounting, regulatory or Tax advice with respect

deemed appropriate. Each Borrower hereby waives and releases, to the full extent permitted by law, any claims that it may have against the Administrative Agent, the Collateral Agent and the Arrangers with respect to any breach or alleged breach of
agency or fiduciary duty. 
 Section 10.16 Intercreditor Agreement. REFERENCE IS MADE TO THE
INTERCREDITOR AGREEMENT. EACH LENDER HEREUNDER AGREES THAT IT WILL BE BOUND BY AND WILL TAKE NO ACTIONS CONTRARY TO THE PROVISIONS OF THE INTERCREDITOR AGREEMENT, CONSENTS TO THE SUBORDINATION OF THE LIENS ON THE CURRENT ASSET COLLATERAL SECURING
THE FINANCE OBLIGATIONS ON THE TERMS SET FORTH IN THE INTERCREDITOR AGREEMENT AND AUTHORIZES AND INSTRUCTS THE ADMINISTRATIVE AGENT TO ENTER INTO THE INTERCREDITOR AGREEMENT AS “ORIGINAL ABL AGENT” AND ON BEHALF OF SUCH LENDER AND TO
SUBJECT THE LIENS ON THE COLLATERAL SECURING THE FINANCE OBLIGATIONS TO THE PROVISIONS THEREOF. THE PROVISIONS OF THIS SECTION 10.16 ARE NOT INTENDED TO SUMMARIZE ALL RELEVANT PROVISIONS OF THE INTERCREDITOR AGREEMENT, THE
FORM OF WHICH IS ATTACHED AS AN EXHIBIT TO THIS AGREEMENT. REFERENCE MUST BE MADE TO THE INTERCREDITOR AGREEMENT ITSELF TO UNDERSTAND ALL TERMS AND CONDITIONS THEREOF. EACH LENDER IS RESPONSIBLE FOR MAKING ITS OWN ANALYSIS AND REVIEW OF
THE INTERCREDITOR AGREEMENT AND THE TERMS AND PROVISIONS THEREOF, AND NEITHER THE ADMINISTRATIVE AGENT NOR ANY OF ITS AFFILIATES MAKES ANY REPRESENTATION TO ANY LENDER AS TO THE SUFFICIENCY OR ADVISABILITY OF THE PROVISIONS CONTAINED IN THE
INTERCREDITOR 

  
 155 

 
AGREEMENT. THE PROVISIONS OF THIS SECTION 10.16 ARE INTENDED AS AN INDUCEMENT TO THE LENDERS UNDER THE TERM CREDIT AGREEMENT TO EXTEND CREDIT THEREUNDER AND SUCH LENDERS
ARE INTENDED THIRD PARTY BENEFICIARIES OF SUCH PROVISIONS AND THE PROVISIONS OF THE INTERCREDITOR AGREEMENT. NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, THE LIENS AND SECURITY INTERESTS GRANTED TO THE ADMINISTRATIVE AGENT OR THE COLLATERAL
AGENT PURSUANT TO THE LOAN DOCUMENTS IN ANY COLLATERAL AND THE EXERCISE OF ANY RIGHT OR REMEDY BY THE ADMINISTRATIVE AGENT OR THE COLLATERAL AGENT WITH RESPECT TO ANY COLLATERAL ARE SUBJECT TO THE PROVISIONS OF THE INTERCREDITOR AGREEMENT. IN THE

arising under any Loan Document, to the extent such liability is unsecured, may be subject to the write-down and conversion powers of an EEA Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by: 

(a) the application of any Write-Down and Conversion Powers by an EEA Resolution Authority to any such liabilities arising hereunder which may
be payable to it by any party hereto that is an EEA Financial Institution; and 
 (b) the effects of any
Bail-in Action on any such liability, including, if applicable: 
 (i) a reduction in full or in
part or cancellation of any such liability; 
 (ii) a conversion of all, or a portion of, such liability into shares or other instruments of
ownership in such EEA Financial Institution, its parent undertaking, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of any rights
with respect to any such liability under this Agreement or any other Loan Document; or 
 (iii) the variation of the terms of such liability
in connection with the exercise of the write-down and conversion powers of any EEA Resolution Authority. 

Section 10.18 Judgment Currency. 

If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due hereunder or any other Loan Document in one
currency into another currency, the rate of exchange used shall be that at which in accordance with normal banking procedures the Administrative Agent could purchase the first currency with such other currency on the Business Day preceding that on
which final judgment is given. The obligation of the Borrowers in respect of any such sum due from them to the Administrative Agent or the Lenders hereunder or under the other Loan Documents shall, notwithstanding any judgment in a currency (the
“Judgment Currency”) other than that in which such sum is denominated in accordance with the applicable provisions of this Loan Agreement (the “Agreement Currency”), be discharged only to the extent that on the
Business Day following receipt by the Administrative Agent of any sum adjudged to be so due in the Judgment Currency, the Administrative Agent may in accordance with normal banking procedures purchase the Agreement Currency with the Judgment
Currency. If the amount of the Agreement Currency so purchased is less than the sum originally due to the Administrative 

  
 156 

 
Agent from the Borrowers in the Agreement Currency, the Borrowers agree, as a separate obligation and notwithstanding any such judgment, to indemnify the Administrative Agent or the Person to
whom such obligation was owing against such loss. If the amount of the Agreement Currency so purchased is greater than the sum originally due to the Administrative Agent in such currency, the Administrative Agent agrees to return the amount of any
excess to the Borrowers (or to any other Person who may be entitled thereto under applicable law)

 EXHIBIT I 

[Form of] Intercompany Note Subordination Provisions 

Each promissory note evidencing an Intercompany Loan or advance incurred by MKS Instruments, Inc. (“MKS”) or another Loan Party owing to any
Subsidiary that is not a Loan Party shall have included on its face the following subordination provision (modified as appropriate in the event the promissory note is a global promissory note): 

(a) Capitalized terms defined in the Term Loan Credit Agreement or the ABL Credit Agreement (each as defined in the promissory note to which
this Exhibit I is attached (the “Intercompany Note”)) (together, the “Credit Agreements”) and not otherwise defined in this Intercompany Note have, as used in this Exhibit I, the respective meanings
provided for in the Credit Agreements, as applicable. 
 (b) Anything in this Intercompany Note to the contrary notwithstanding, the
indebtedness evidenced by this Intercompany Note owed by any Payor that is a Loan Party to any Payee that is not a Loan Party shall be subordinate and junior in right of payment, to the extent and in the manner hereinafter set forth, to all Finance
Obligations of such Payor under the Credit Agreements, including, without limitation, where applicable, under such Payor’s guarantee of the Finance Obligations under the Credit Agreements (such Finance Obligations and other indebtedness and
obligations in connection with any renewal, refunding, restructuring or refinancing thereof, including interest thereon accruing after the commencement of any proceedings referred to in clause (i) below, whether or not such interest is an
allowed claim in such proceeding, being hereinafter collectively referred to as “Credit Agreement Indebtedness”). The Credit Agreement Indebtedness is referred to herein as “Senior Indebtedness”. 

 

	 	(i)	 In the event of any insolvency or bankruptcy proceedings, and any receivership, examinership, liquidation,
reorganization or other similar proceedings in connection therewith, relative to any such Payor or to its creditors, as such, or to its property, and in the event of any proceedings for voluntary liquidation, dissolution or other winding up of such
Payor, whether or not involving insolvency or bankruptcy, then (x) the holders of Senior Indebtedness shall be paid in full in cash in respect of all amounts constituting Senior Indebtedness before any such Payee is entitled to receive (whether
directly or indirectly), or make any demands for, any payment on account of this Intercompany Note and (y) until the holders of Senior Indebtedness are paid in full in cash in respect of all amounts constituting Senior Indebtedness, any payment
or distribution to which such Payee would otherwise be entitled (other than debt securities of such Payor that are subordinated, to at least the same extent as this Intercompany Note, to the payment of all Senior Indebtedness then outstanding (such
securities being hereinafter referred to as “Restructured Debt Securities”)) shall be made to the holders of Senior Indebtedness. 

  

	 	(ii)	 If any Event of Default occurs and is continuing with respect to any Senior Indebtedness (including any Event
of Default under the Credit Agreements), then no payment or distribution of any kind or character shall be made by or on behalf of such Payor or any other Person on its behalf with respect to this Intercompany Note unless the Payee is a Loan Party.

  
 Exhibit I-1 

	 	(iii)	 If any payment or distribution of any character by any such Payor that is a Loan Party, whether in cash,
securities or other property (other than Restructured Debt Securities), in respect of this Intercompany Note shall (despite these subordination provisions) be received by any such Payee that is not a Loan Party in violation of clause (i) or
(ii) before all Senior Indebtedness shall have been paid in full in cash, such payment or distribution shall be held in trust for the benefit of, and shall be paid over or delivered to the Administrative Agent, as applicable, on behalf of the
holders of Credit Agreement Indebtedness, to the extent necessary to pay all Senior Indebtedness in full in cash. 

  

	 	(iv)	 To the fullest extent permitted by law, no present or future holder of Senior Indebtedness shall be prejudiced
in its right to enforce the subordination of this Intercompany Note by any act or failure to act on the part of any such Payor or by any act or failure to act on the part of such holder or any trustee or agent for such holder. Each such Payee and
each such Payor hereby agree that the subordination of this Intercompany Note is for the benefit of the Administrative Agent and holders of Senior Indebtedness and the holders of Senior Indebtedness are obligees under this Intercompany Note to the
same extent as if their names were written herein as such and the Administrative Agent may, on behalf of Finance Parties under the Credit Agreements, proceed to enforce the subordination provisions herein. 

 

	 	(v)	 The indebtedness evidenced by this Intercompany Note owed by any Payor to any Loan Party shall not be
subordinated to, and shall rank pari passu in right of payment with, any other obligation of such Payor. 

  

	 	(vi)	 Nothing contained in this subordination provision is intended to or will impair, as between each Payor and each
Payee, the obligations of such Payor, which are absolute and unconditional, to pay to such Payee the principal of and interest on this Intercompany Note as and when due and payable in accordance with its terms, or is intended to or will affect the
relative rights of such Payee and other creditors of such Payor other than the holders of Senior Indebtedness.

for which they have unreasonably small capital. 

 For purposes of this 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. This Certificate is to be interpreted in accordance with the laws of the State of New York. 
 The undersigned is familiar with
the business and financial position of MKS and its Subsidiaries. In reaching the conclusions set forth in this Certificate, the undersigned has made such other investigations and inquiries as the undersigned has deemed appropriate, having taken into

[FORM OF] LANDLORD AGREEMENT AND WAIVER 
 For
good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, __________________, a _________________ (the “Landlord”) executes this agreement and waiver in favor of (1) BARCLAYS BANK
PLC, as administrative agent (in such capacity and together with any successor acting in such capacity, the “Administrative Agent”) for its own benefit and the benefit of certain other lenders and secured parties (collectively
the “Credit Parties”) which are making loans or furnishing other financial accommodations to the Tenant (as defined below) and certain of its affiliates (collectively, the “Borrowers”), and (2) [GRANTOR], a
[                ][corporation][limited liability company] (the “Tenant”). 

WITNESSETH: 
 WHEREAS, the
Landlord has an interest in the real property located at ______________________ (collectively, the “Leased Premises”), which real property the Landlord leases, or will lease, to the Tenant, pursuant to a certain lease dated
____________________, ____ between the Landlord and the Tenant (as amended, the “Lease”). 
 WHEREAS, the Borrowers have
entered into that certain ABL Credit Agreement dated as of February 1, 2019 (as may be amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Loan Agreement”), with the
Administrative Agent and the Credit Parties, pursuant to which the Administrative Agent and the Credit Parties have agreed to make loans or furnish other financial accommodations to the Borrowers. 

WHEREAS, loans and financial accommodations under the Loan Agreement will be secured by, among other things, certain of the Tenant’s
present and after acquired assets (the “Collateral”), including, without limitation, the Tenant’s inventory, equipment and other personal property located, and to be located, upon the Leased Premises. 

WHEREAS, in order to induce the Administrative Agent and the Credit Parties to make loans or furnish other financial accommodations to the
Borrowers, the Landlord hereby represents, warrants, covenants and agrees with the Administrative Agent as follows: 
  

	1.	 The Landlord acknowledges the Administrative Agent’s lien on the Collateral and hereby subordinates any
lien or interest or right that it may have in any of the Collateral of Tenant. The Landlord agrees that if any of the Collateral may be or may become affixed to the Leased Premises, such Collateral shall remain personal property notwithstanding the
manner in which the same is affixed to the Leased Premises. 

  

	2.	 If an Event of Default (as defined in the Loan Agreement) has occurred and is continuing or if the Landlord
takes possession of the Leased Premises for any reason, including because of termination of the Company’s lease (each a “Disposition Event”), the Landlord agrees, that at the Administrative Agent’s option, the Collateral
may remain upon the Premises for a period not to exceed one-hundred twenty (120) days (or such shorter period as is reasonably acceptable to the Administrative Agent) (the “Disposition
Period”) after the Administrative Agent receiving access to the Leased Premises; provided, however, that to the extent the Tenant has not so already paid, the Administrative Agent pays rent and other additional charges on a
per diem basis for the period of time the Administrative Agent remains on the Premises, based upon the amount set forth in the Lease, it being understood, however, that the Administrative Agent shall not, thereby, have

  
 Exhibit N-1 

	 	
assumed any of the obligations of the Tenant to the Landlord, including, without limitation, any obligation to pay any past due rent owing by the Tenant. If any injunction or stay is issued (in
any bankruptcy, insolvency or similar proceeding) that prohibits the Administrative Agent from removing the Collateral, commencement of the Disposition Period shall be deferred until such injunction or stay is lifter or removed. During the
Disposition Period, the Landlord will, upon reasonable prior written notice from the Administrative Agent, cooperate with the Administrative Agent in gaining access to the Leased Premises for the purpose of repossessing said Collateral. The
Administrative Agent shall promptly repair, at the Administrative Agent’s expense, any physical damage to the Leased Premises actually caused by the inspection or removal of the Collateral, but shall not be liable for any diminution in value of
the Leased Premises caused by the removal or absence of the Collateral. 

  

	3.	 All notices, requests or demand under this agreement and waiver shall be made to the following addresses by
recognized overnight courier, by hand delivery or by facsimile transmission:

reason, be deemed void, voidable, or unenforceable, the remaining terms and conditions hereof shall remain in full force and effect as though such void, voidable or unenforceable provisions were not included. In the event any of the provisions,
