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

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

 (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 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. 
 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 

  
 55 







Table of Contents


 
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. 

(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,


  
 56 







Table of Contents


 
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. 
 (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 Administrative Agent and
MKS, designate such Restricted Subsidiary as a “Borrower” for purposes of this Agreement. Such designation shall become effective upon the execution and delivery to the Administrative Agent of (i) 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 the joinder of such Restricted Subsidiary as a Borrower hereunder and (iv) if such Subsidiary is not already a Guarantor,
all Collateral Documents, guarantees, opinions and other documents and instruments as such Subsidiary shall be required to deliver to become a Guarantor and such other documents in form, content and scope reasonably satisfactory to the
Administrative Agent as may be reasonably required by the Administrative Agent and all documentation and other information required by regulatory authorities under applicable “know your customer” and anti-money laundering rules and
regulations. The Administrative Agent shall promptly notify each Lender of each such designation by a Borrower, the identity of the respective Subsidiary and the effective date of such joinder.

THE CREDIT FACILITIES 

Section 2.01 Commitments To Lend. 

(a) Revolving Loans. Subject solely to the terms and conditions set forth herein, each Lender severally agrees to make Loans to
a Borrower in Dollars or any Alternative Currency pursuant to this Section 2.01(a) from time to time during the Revolving Availability Period in amounts such that its Revolving Outstandings shall not exceed (after giving effect to all
Revolving Loans repaid and all reimbursements of L/C Disbursements made concurrently with the making of any Revolving Loans) its Revolving Commitment; provided that (x) the Revolving Loans drawn on the Closing Date shall only be used to
pay for the Closing Date Refinancing, to provide ongoing working requirements of MKS and its Subsidiaries and to pay Transaction Costs and any original issue discount or upfront fees that result from the exercise of the “Market Flex”
provisions in the Fee Letter and (y) immediately after giving effect to each such Loan, (i) the aggregate Revolving Outstandings shall not exceed the Line Cap, (ii) with respect to each Revolving Lender individually, such
Lender’s outstanding 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 and
(iii) the aggregate Revolving Outstandings denominated in an Alternative Currency shall not exceed $10,000,000 (the “Alternative Currency Sublimit”). Each Revolving Borrowing comprised of Eurodollar Loans shall be in an
aggregate principal amount of $1,000,000 or any larger multiple of $100,000, and each Revolving Borrowing comprised of Base Rate Loans shall be in an aggregate principal amount of $500,000 or any larger multiple of $100,000 (except that any such
Revolving Borrowing may be in the aggregate amount of the unused Revolving Commitments and any L/C Borrowing may be in the aggregate amount of any outstanding Unreimbursed Amounts owed to one or more L/C Issuers as provided in
Section 2.05(e)(iv)) and shall be made from the several Revolving Lenders ratably in proportion to their respective Revolving Commitments. No more than ten (10) Revolving Borrowings shall be outstanding at any time. Within the
foregoing limits, the Borrowers may borrow under this Section 2.01(a), repay, or, to the extent permitted by Section 2.09, prepay, and reborrow Revolving Loans under this Section 2.01(a). 

Section 2.02 Notice of Borrowings. 

(a) Revolving Borrowings. Except in the case of L/C Borrowings, each Borrower shall give the Administrative Agent a Notice of Borrowing
substantially in the form of Exhibit A-1 not later than 12:00 P.M. on (i) the first Business Day before the proposed Base Rate Borrowing and (ii) the third Business Day before each proposed Eurodollar Loan (unless such Borrower
wishes to request an Interest Period for such Revolving Borrowing other than one (1), three (3) or six (6) months in duration as provided in the definition of “Interest Period” or such proposed Eurodollar Loan is denominated in
an Alternative Currency, in which case on the fourth Business Day before each such Eurodollar Loan), specifying: 
 (i) the
date of such Revolving Borrowing, which shall be a Business Day; 
 (ii) the aggregate amount of such Revolving Borrowing;

 (iii) the initial Type of the Loans comprising such Revolving Borrowing and the currency in which such Loans are
denominated;

Table of Contents


 (iv) in the case of a Eurodollar Loan, the duration of the initial Interest
Period applicable thereto, subject to the provisions of the definition of “Interest Period” and to Section 2.06(a); and 

(v) the location (which must be in the United States) and number of such Borrower’s account, to which funds are to be
disbursed, which shall comply with the requirements of Section 2.03. 
 If the duration of the initial Interest Period is not specified with
respect to any requested Eurodollar Loan, then the Borrowers shall be deemed to have selected an initial Interest Period of one (1) month, subject to the provisions of the definition of “Interest Period” and to
Section 2.06(a). 
 (b) L/C Borrowings. Each L/C Borrowing shall be made as specified in Section 2.05(e)(iv)
without the delivery of a Notice of Borrowing. 
 Section 2.03 Notice to Lenders; Funding of Loans. 

(a) Notice to Lenders. If a Borrower has requested an Interest Period of other than one (1), three (3) or six
(6) months in duration, the Administrative Agent shall give prompt notice of such request to the applicable Lenders and determine whether the requested Interest Period is acceptable to all of them. Not later than 11:00 A.M. on the third
Business Day before the requested date of such a Eurodollar Loan, the Administrative Agent shall notify such Borrower whether or not the requested Interest Period has been consented to by all the Lenders. Upon receipt of a Notice of Borrowing, the
Administrative Agent shall promptly notify each Lender of such Lender’s ratable share (if any) of the Revolving Borrowing referred to therein, and such Notice of Borrowing shall not thereafter be revocable by any Borrower. 

(b) Funding of Loans. Not later than 1:00 P.M. on the date of each Revolving Borrowing, each Lender participating therein shall
make available its share of such Revolving Borrowing, in Federal or other immediately available funds, to the Administrative Agent at the Administrative Agent’s Office. Unless the Administrative Agent determines that any applicable condition
specified in Article IV has not been satisfied, the Administrative Agent shall make the funds so received available to the applicable Borrower in like funds as received by the Administrative Agent either by (A) crediting the account of
such Borrower on the books of the Administrative Agent with the amount of such funds or (B) wire transfer of such funds, in each case in accordance with instructions provided to (and reasonably acceptable to) the Administrative Agent by such
Borrower in the applicable Notice of Borrowing, or, if a Revolving Borrowing shall not occur on such date because any condition precedent herein shall not have been met, promptly return the amounts received from the Lenders in like funds, without
interest. 
 Not later than 1:00 P.M. on the date of each L/C Borrowing, each Revolving Lender shall make available its share of such
Borrowing, in Federal or other immediately available funds, to the Administrative Agent at the Administrative Agent’s Office. The Administrative Agent shall remit the funds so 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 

  
 59 







Table of Contents


 
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 obligation of any Borrower hereunder
to pay any amount owing with respect to the Senior Credit 

  
 60 







Table of Contents


 
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.

 (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-3 hereto (a “Letter of Credit Request”), appropriately completed and signed by a 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


  
 62 







Table of Contents


 
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 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. 

  
 64 







Table of Contents


 (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).

 (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.

 (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.

Table of Contents


 (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”).

Table of Contents


 (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 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.

Table of Contents


 (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-2 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; 

  
 71 







Table of Contents


 (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. 

  
 72 







Table of Contents


 (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 (which notice may be conditional on the occurrence of an event to the extent specified in such notice). Each notice of prepayment shall be substantially in the form of Exhibit O
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.

 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
June 30, 2016. 
 (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 Collateral pursuant to


  
 74 







Table of Contents


 
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 last Business Day after the end 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 Arranger Fee Letter and the Administrative Agent 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. 
 (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 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 

  
 76 







Table of Contents


 
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 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 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. 

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. 
 (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; 

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 

  
 80 







Table of Contents


 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. 

(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). 
 (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 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 two 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. 
 (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; 

  
 84 







Table of Contents


 (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. 
 (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 

  
 85 







Table of Contents


 
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 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 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. 

Section 3.04 Increased Costs and Reduced Return; Capital Adequacy. 

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

(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 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 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;

Table of Contents


 (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, 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.

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.

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,

to 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,

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.

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:

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

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

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

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).

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 DBNY 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 DBNY 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. 
 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

 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.” 

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 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. 

Any resignation by DBNY 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. 
 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

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

(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. 
 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.

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. 
 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.

 (i) extend or increase the Commitment of any Lender without the written consent of such Lender (it being

 (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 pro
rata sharing of payments or the order of payment required thereby without the written consent of each Lender directly affected thereby;

 (v) except in connection with the implementation of any Incremental Facility,
change any provision of this Section 10.01 or the definition of “Applicable Percentage”, “Required Lenders” or “Supermajority Lenders” or any other provision hereof specifying the percentage of Lenders
required to amend, waive or otherwise modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender;

 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

Lenders and the L/C Issuers hereunder may (subject to Section 10.02(d)) be delivered or furnished by electronic communication (including e-mail and Internet or intranet websites) pursuant to procedures approved by the Administrative
Agent; provided that the foregoing shall not apply to notices to any Lender or L/C Issuer pursuant to Article II if such Lender or L/C Issuer, as applicable, has notified the Administrative Agent that it is incapable of receiving
notices under such Article by electronic communication. The Administrative Agent, the Collateral Agent or any Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by 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. 

Unless the Administrative Agent otherwise prescribes, (i) notices and other communications sent to an e-mail address shall be deemed
received upon the sender’s receipt of an acknowledgement from the intended recipient (such as by the “return receipt requested” function, as available, return e-mail or other written acknowledgement); provided that if such

change its address or telecopier number for notices and other communications hereunder by notice to the other parties hereto. In addition, each Lender agrees to notify the Administrative Agent from time to time to ensure that the Administrative

(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

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.

Table of Contents


 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. 
 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

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.

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

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

(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. 

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

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

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 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. 
 (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 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,

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 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 or (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. 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 

  
 147 







Table of Contents


 
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 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 Letter 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. 
 (a) Governing Law. This Agreement and the other Loan Documents and any claims,
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

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 in the courts of any jurisdiction. 

(c) Waiver of Venue. Each party hereby irrevocably and unconditionally waives, to the full extent permitted by applicable Laws,
any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in Section 10.13(b). Each of the
parties hereto hereby irrevocably waives, to the full extent permitted by applicable Law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

applicable Laws, any right it may have to a trial by jury in any legal proceeding directly or indirectly arising out of or relating to this Agreement, any other Loan Document or the transactions contemplated hereby (whether based on contract, tort
or any other theory). Each party hereto (a) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce the
foregoing waiver and (b) acknowledges that it and the other parties hereto have been induced to enter into this Agreement by, among other things, the mutual waivers and certifications in this Section 10.13.

(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 number of each Loan Party

provided for hereunder 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

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

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 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

 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 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)

 GUARANTY 

GUARANTY dated as of April 29, 2016 (as amended, restated, supplemented or otherwise modified from time to time, this
“Agreement”), by and among MKS Instruments, Inc., a Massachusetts corporation (“MKS”), the Subsidiaries listed on the signature pages hereto and each of the Subsidiaries of a Borrower, which shall become from time
to time party hereto in accordance with Section 6.09 of the Credit Agreement (defined below) (each, a “Guarantor” and collectively, the “Guarantors”) and Deutsche Bank AG New York Branch, as Administrative
Agent for the benefit of the Finance Parties. 
 MKS has entered into that certain ABL Credit Agreement, dated as of the date hereof (as
amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”), by and among MKS, the other Borrowers from time to time party thereto, the lending institutions from time to time party thereto (each
a “Lender” and, collectively, the “Lenders”) and Deutsche Bank AG New York Branch, as Administrative Agent, Collateral Agent and L/C Issuer (together with its successor or successors in each such capacity, the
“Administrative Agent”, the “Collateral Agent” and the “L/C Issuer”, respectively). All capitalized terms used herein and not otherwise defined herein shall have the meanings ascribed thereto in the
Credit Agreement. 
 To induce the Credit Parties to enter into the Credit Agreement and the other Loan Documents, and as a condition
precedent to the obligations of the Credit Parties under the Credit Agreement, each of the Guarantors has agreed to provide a guaranty of all obligations of the Borrowers and the other Loan Parties under and in respect of the Finance Documents. As
used herein, “Other Loan Parties” means, with respect to any Guarantor or any Borrower, any and all of the Loan Parties other than such Guarantor or such Borrower, as applicable. 

Each Guarantor is a Subsidiary of the MKS, and the Guarantors will receive substantial direct and indirect benefits from the extension of
credit to the Borrowers and other financial accommodations to be provided by the Finance Parties under the Finance Documents. Accordingly, the Guarantors hereby agree with the Administrative Agent for the benefit of the Finance Parties as
follows: 
 ARTICLE I 

GUARANTY 
 Section
1.01 The Guaranty. Each Guarantor unconditionally guarantees, jointly with the other Guarantors, and severally, as a primary obligor and not merely as a surety: (x) the due and punctual payment of all Senior Credit Obligations
of the Borrowers, whether now or hereafter due, owing or incurred in any manner, whether actual or contingent, whether incurred solely or jointly with any other Person and whether as principal or surety (and including all liabilities in connection
with any notes, bills or other instruments accepted by any Credit Party in connection therewith), together in each case with all renewals, modifications, consolidations or extensions thereof and (y) the due and punctual performance of all
covenants, agreements, obligations and liabilities of the Borrowers and the Other Loan Parties under or pursuant to the Loan Documents and the other Finance Documents (all such monetary and other obligations being herein collectively referred to as
the “Guaranteed Obligations”). 
 Anything contained in this Agreement to the contrary notwithstanding, the obligations of
each Guarantor hereunder shall be limited to a maximum aggregate amount equal to the greatest amount that would not render such Guarantor’s obligations hereunder subject to avoidance as a fraudulent transfer or conveyance under Section 548
of Title 11 of the United States Code or any provisions of applicable state law (collectively, the “Fraudulent Transfer Laws”), in each case after giving effect to all other liabilities of such Guarantor, contingent or
otherwise, that are relevant under the Fraudulent Transfer 






Table of Contents


 
Laws (specifically excluding, however, any liabilities of such Guarantor (i) in respect of intercompany indebtedness to the Borrowers or any of their Affiliates to the extent that such
indebtedness (A) would be discharged or would be subject to a right of set-off in an amount equal to the amount paid by such Guarantor hereunder or (B) has been pledged to, and is enforceable by, the Collateral Agent on behalf of the
Finance Parties and (ii) under any guaranty of Indebtedness subordinated in right of payment to the Guaranteed Obligations which guaranty contains a limitation as to a maximum amount similar to that set forth in this paragraph pursuant to which
the liability of such Guarantor hereunder is included in the liabilities taken into account in determining such maximum amount) and after giving effect as assets of such Guarantor to the value (as determined under the applicable provisions of the
Fraudulent Transfer Laws) of any rights to subrogation, contribution, reimbursement, indemnity or similar rights of such Guarantor pursuant to (i) applicable Law or (ii) any agreement providing for an equitable allocation among such
Guarantor and other Affiliates of the Borrowers of obligations arising under guaranties by such parties (including the agreements in Article II). If any Guarantor’s liability hereunder is limited pursuant to this
paragraph to an amount that is less than the total amount of the Guaranteed Obligations, then it is understood and agreed that the portion of the Guaranteed Obligations for which such Guarantor is liable hereunder shall be the last portion of the
Guaranteed Obligations to be repaid. 
 Section 1.02 Guaranty Absolute. Each Guarantor guarantees that the
Guaranteed Obligations will be paid strictly in accordance with the terms of the Finance Documents, regardless of any Law now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Finance Parties with respect
thereto. The obligations of the Guarantors under this Agreement are independent of the Guaranteed Obligations, and a separate action or actions may be brought and prosecuted against each Guarantor to enforce this Agreement, irrespective of
whether any action is brought against any Borrower or any Other Loan Party or whether any Borrower or any Other Loan Party is joined in any such action or actions. This Agreement is an absolute and unconditional guaranty of payment when due,
and not of collection, by each Guarantor, jointly and severally with each other Guarantor of the Guaranteed Obligations in each and every particular. The obligations of each Guarantor hereunder are several from those of the Other Loan Parties
and are primary obligations concerning which each Guarantor is the principal obligor. The Finance Parties shall not be required to mitigate damages or take any action to reduce, collect or enforce the Guaranteed Obligations. 

Subject to Section 5.11, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or
termination for any reason, including the existence of any claim, set-off or other right which any Guarantor may have at any time against any Other Loan Party, any Agent or other Finance Party or any other Person, whether in connection herewith or
any unrelated transactions. Without limiting the generality of the foregoing, each Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by any Other Loan Party to any Finance
Party under the Finance Documents but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving such Borrower or such Other Loan Party. 

Without limiting the generality of the foregoing, the obligations of each Guarantor hereunder shall not be released, discharged or otherwise
affected or impaired by: 
 (i) any extension, renewal, settlement, compromise, acceleration, waiver or release in respect of
any obligation of any Other Loan Party under the Credit Agreement, the Notes, any Swap Agreement, any other Finance Document or any other agreement or instrument evidencing or securing any Guaranteed Obligation, by operation of Law or otherwise
(except as provided herein or in any other Finance Document);

Table of Contents


 (ii) any change in the manner, place, time or terms of payment of any Guaranteed
Obligation or any other amendment, supplement or modification to the Credit Agreement, the Notes, any Swap Agreement, any other Finance Document or any other agreement or instrument evidencing or securing any Guaranteed Obligation; 

(iii) any release, non-perfection or invalidity of any direct or indirect security for any Guaranteed Obligation, any sale,
exchange, surrender, realization upon, offset against or other action in respect of any direct or indirect security for any Guaranteed Obligation or any release of any Other Loan Party or any other guarantor or guarantors of any Guaranteed
Obligation (except as provided herein or in any other Finance Document); 
 (iv) any change in the existence, structure or
ownership of any Other Loan Party or any insolvency, examinership, bankruptcy, reorganization, arrangement, readjustment, composition, liquidation or other similar proceeding affecting any Other Loan Party or its assets or any resulting
disallowance, release or discharge of all or any portion of any Guaranteed Obligation; 
 (v) the existence of any claim,
set-off or other right which any Guarantor may have at any time against any Other Loan Party, any Agent, any other Finance Party or any other Person, whether in connection herewith or any unrelated transaction; provided that nothing herein
shall prevent the assertion of any such claim by separate suit or compulsory counterclaim; 
 (vi) any invalidity or
unenforceability relating to or against any Other Loan Party for any reason of the Credit Agreement, any Note, any Swap Agreement, any other Finance Document or any other agreement or instrument evidencing or securing any Guaranteed Obligation or
any provision of applicable Law purporting to prohibit the payment by any Other Loan Party of any Guaranteed Obligation; 

(vii) any failure by any Agent or any other Finance Party: (A) to file or enforce a claim against any Other Loan Party or
its estate (in a bankruptcy, examinership or other proceeding); (B) to give notice of the existence, creation or incurrence by any Other Loan Party of any new or additional indebtedness or obligation under or with respect to the Guaranteed
Obligations; (C) to commence any action against any Other Loan Party; (D) to disclose to any Guarantor any facts which such Agent or such other Finance Party may now or hereafter know with regard to any Other Loan Party; or (E) to
proceed with due diligence in the collection, protection or realization upon any collateral securing the Guaranteed Obligations; 

(viii) any direction as to application of payment by any Other Loan Party or any other Person; 

(ix) any subordination by any Finance Party of the payment of any Guaranteed Obligation to the payment of any other liability
(whether matured or unmatured) of any Other Loan Party to its creditors; 
 (x) any act or failure to act by the
Administrative Agent or any other Finance Party under this Agreement or otherwise which may deprive any Guarantor of any right to subrogation, contribution or reimbursement against any Other Loan Party or any right to recover full indemnity for any
payments made by such Guarantor in respect of the Guaranteed Obligations; or 
 (xi) any other act or omission to act or
delay of any kind by any Other Loan Party, the Administrative Agent or any Finance Party or any other Person or any other circumstance whatsoever which might, but for the provisions of this clause, constitute a legal or equitable discharge of any
Guarantor’s obligations hereunder (except that a Guarantor may assert the defense of payment in full of the Guaranteed Obligations).

Table of Contents


 Each Guarantor irrevocably and unconditionally has delivered this Agreement to the Administrative
Agent for the benefit of the Finance Parties, and the failure by any Other Loan Party or any other Person to sign this Agreement or a guaranty similar to this Agreement or otherwise shall not discharge the obligations of any Guarantor
hereunder. The irrevocable and unconditional liability of each Guarantor hereunder applies whether it is jointly and severally liable for the entire amount of the Guaranteed Obligations, or only for a pro-rata portion, and without regard
to any rights (or the impairment thereof) of subrogation, contribution or reimbursement that such Guarantor may now or hereafter have against any Other Loan Party or any other Person. This Agreement is and shall remain fully enforceable against
each Guarantor (except as provided herein or in any other Finance Document) irrespective of any defenses that any Other Loan Party may have or assert in respect of the Guaranteed Obligations, including, without limitation, failure of consideration,
breach of warranty, payment, statute of frauds, statute of limitations, accord and satisfaction and usury, except that a Guarantor may assert the defense of final payment in full of the Guaranteed Obligations. 

Section 1.03 Payments. 

(a) Payments to be Made Upon Default. If any Borrower or any Other Loan Party fails to pay or perform any
Guaranteed Obligation when due in accordance with its terms (whether at stated maturity, by acceleration or otherwise) or if any Event of Default under the Credit Agreement occurs with respect to the Borrowers, the Guarantors shall, forthwith on
demand of the Administrative Agent, pay the aggregate amount of all Guaranteed Obligations owed respectively to the Administrative Agent. 

(b) General Provisions as to Payments. Except as provided in Section 3.01 of the Credit Agreement, each
payment hereunder shall be made without set-off, counterclaim or other deduction, in federal or other funds immediately available in New York City, to the Administrative Agent at the address referred to in Section 5.01 (it
being understood that a Guarantor may assert the defense of final payment in full of the Guaranteed Obligations). 
 (c) Application
of Payments. All payments received by the Administrative Agent hereunder shall be applied as provided in Section 8.03 of the Credit Agreement. 

Section 1.04 Discharge; Reinstatement in Certain Circumstances. Each Guarantor’s obligations hereunder shall remain
in full force and effect until the earlier of (i) the Discharge of Senior Credit Obligations (as defined in the Credit Agreement) and (ii) such time as such Guarantor is no longer required to be a Guarantor under the Credit Agreement or
pursuant to Section 5.11(b) of this Agreement (such time, the “Termination Date”). No payment or payments made by any Borrower, any Other Loan Party or any other Person or received or collected by any Finance Party from the
Borrowers, any Other Loan Party 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 Guaranteed Obligations shall be deemed to
modify, reduce, release or otherwise affect the liability of any Guarantor hereunder, it being understood that each Guarantor shall, notwithstanding any such payment or payments, remain liable for the Guaranteed Obligations until the Termination
Date. If at any time any payment by any Borrower, any Other Loan Party or any other Person of any Guaranteed Obligation is rescinded or must otherwise be restored or returned upon the insolvency, examinership, bankruptcy,

dissolution, liquidation or reorganization of such Borrower or such Other Loan Party or other Person or upon or as a result of the appointment of a receiver, examiner, intervener or conservator
of, or trustee or similar officer for, such Borrower or such Other Loan Party or other Person or any substantial part of its respective property or otherwise, each Guarantor’s obligations hereunder with respect to such payment shall be
reinstated as though such payment had been due but not made at such time. Each Guarantor agrees that payment or performance of any of the Guaranteed Obligations or other acts which toll any statute of limitations applicable to the Guaranteed
Obligations shall also toll the statute of limitations applicable to each Guarantor’s liability hereunder. 
 Section 1.05
Waiver by the Guarantors. Each Guarantor hereby waives, only to the extent permitted by applicable Law, presentment to, demand of payment from and protest to the Other Loan Parties of any of the Guaranteed Obligations, and also waives
to the extent permitted by applicable Law, promptness, diligence, notice of acceptance of its guarantee, any other notice with respect to any of the Guaranteed Obligations and this Agreement and any requirement that any Agent or any other Finance
Party protect, secure, perfect or insure any Lien or any property subject thereto. Each Guarantor further waives to the extent permitted by applicable Law, any right to require that resort be had by any Agent or any other Finance Party to any
security held for payment of the Guaranteed Obligations or to any balance of any deposit, account or credit on the books of any Agent or any other Finance Party in favor of any Loan Party or any other Person. Each Guarantor hereby consents and
agrees to each of the following to the fullest extent permitted by Law, and agrees that such Guarantor’s obligations under this Agreement shall not be released, diminished, impaired, reduced or adversely affected by any of the following, and
waives to the extent permitted by applicable Law, any rights (including rights to notice) which such Guarantor might otherwise have as a result of or in connection with any of the following: 

(i) any renewal, extension, modification, increase, decrease, alteration or rearrangement of all or any part of the Guaranteed
Obligations or any instrument executed in connection therewith, or any contract or understanding with any Other Loan Party, any Agent, the other Finance Parties, or any of them, or any other Person, pertaining to the Guaranteed Obligations; 

(ii) any adjustment, indulgence, forbearance or compromise that might be granted or given by any Agent or any other Finance
Party to any Other Loan Party or any other Person liable on the Guaranteed Obligations; or the failure of any Agent or any other Finance Party to assert any claim or demand or to exercise any right or remedy against any Other Loan Party under the
provisions of any Finance Document or otherwise; or any rescission, waiver, amendment or modification of, or any release from any of the terms or provisions of, any Finance Document or any other agreement, including with respect to any Other Loan
Party under this Agreement; 
 (iii) the insolvency, examinership, bankruptcy, arrangement, adjustment, composition,
liquidation, disability, dissolution or lack of power of any Other Loan Party or any other Person at any time liable for the payment of all or part of the Guaranteed Obligations; or any dissolution of any Other Loan Party, or any change,
restructuring or termination of the corporate structure or existence of any Other Loan Party, or any sale, lease or transfer of any or all of the assets of any Other Loan Party, or any change in the shareholders, partners, or members of any Other
Loan Party; or any default, failure or delay, willful or otherwise, in the performance of the Guaranteed Obligations; 
 (iv)
the invalidity, illegality or unenforceability of all or any part of the Guaranteed Obligations, or any document or agreement executed in connection with the Guaranteed Obligations, for any reason whatsoever, including the fact that the Guaranteed

Table of Contents


 
Obligations, or any part thereof, exceed the amount permitted by Law, the act of creating the Guaranteed Obligations or any part thereof is ultra vires, the officers or representatives
executing the documents or otherwise creating the Guaranteed Obligations acted in excess of their authority, the Guaranteed Obligations violate applicable usury Laws, any Other Loan Party has valid defenses, claims or offsets (whether at Law, in
equity or by agreement) which render the Guaranteed Obligations wholly or partially uncollectible from such Other Loan Party, the creation, performance or repayment of the Guaranteed Obligations (or the execution, delivery and performance of any
document or instrument representing part of the Guaranteed Obligations or executed in connection with the Guaranteed Obligations or given to secure the repayment of the Guaranteed Obligations) is illegal, uncollectible, legally impossible or
unenforceable, or the documents or instruments pertaining to the Guaranteed Obligations have been forged or otherwise are irregular or not genuine or authentic; 

(v) any full or partial release of the liability of any Other Loan Party or of any other Person now or hereafter liable,
whether directly or indirectly, jointly, severally, or jointly and severally, to pay, perform, guarantee or assure the payment of the Guaranteed Obligations or any part thereof, it being recognized, acknowledged and agreed by each Guarantor that
such Guarantor may be required to pay the Guaranteed Obligations in full without assistance or support of any other Person, and such Guarantor has not been induced to enter into this Agreement on the basis of a contemplation, belief, understanding
or agreement that any party other than the Borrowers will be liable to perform the Guaranteed Obligations, or that the Finance Parties will look to any other party to perform the Guaranteed Obligations; 

(vi) the taking or accepting of any other security, collateral or guarantee, or other assurance of payment, for all or any part
of the Guaranteed Obligations; 
 (vii) any release, surrender, exchange, subordination, deterioration, waste, loss or
impairment (including negligent, willful, unreasonable or unjustifiable impairment) of any letter of credit, collateral, property or security, at any time existing in connection with, or assuring or securing payment of, all or any part of the
Guaranteed Obligations; 
 (viii) any right that any Guarantor may now or hereafter have under Section 3-606 of the UCC
or otherwise to unimpaired collateral; 
 (ix) the failure of any Agent, any other Finance Party or any other Person to
exercise diligence or reasonable care in the preservation, protection, enforcement, sale or other handling or treatment of all or any part of such collateral, property or security; 

(x) the fact that any collateral, security, security interest or lien contemplated or intended to be given, created or granted
as security for the repayment of the Guaranteed Obligations shall not be properly perfected or created, or shall prove to be unenforceable or subordinate to any other security interest or lien, it being recognized and agreed by each Guarantor that
such Guarantor is not entering into this Agreement in reliance on, or in contemplation of the benefits of, the validity, enforceability, collectability or value of any of the Collateral; 

(xi) any payment by any Other Loan Party to the Administrative Agent, any other Agent or any other Finance Party being held to
constitute a preference under Title 11 of the United States Code or any similar federal, foreign or state Law, or for any reason any Agent or any other Finance Party being required to refund such payment or pay such amount to any Other Loan
Party or someone else;

Table of Contents


 (xii) any other action taken or omitted to be taken with respect to the
Guaranteed Obligations, or the security and collateral therefor, whether or not such action or omission prejudices any Guarantor or increases the likelihood that any Guarantor will be required to pay the Guaranteed Obligations pursuant to the terms
hereof, it being the unambiguous and unequivocal intention of each Guarantor that such Guarantor shall be obligated to pay the Guaranteed Obligations when due, notwithstanding any occurrence, circumstance, event, action or omission whatsoever,
whether or not contemplated, and whether or not otherwise or particularly described herein, except for the full payment and satisfaction of the Guaranteed Obligations in cash; 

(xiii) the fact that all or any of the Guaranteed Obligations cease to exist by operation of Law, including by way of a
discharge, limitation or tolling thereof under applicable bankruptcy Laws; 
 (xiv) the existence of any claim, set-off or
other right which any Guarantor may have at any time against any Other Loan Party, the Administrative Agent, any other Finance Party or any other Person, whether in connection herewith or any unrelated transactions; provided that nothing
herein shall prevent the assertion of any such claim by separate suit or compulsory counterclaim; and 
 (xv) any other
circumstance that might in any manner or to any extent otherwise constitute a defense available to, vary the risk of, or operate as a discharge of, such Guarantor as a matter of Law or equity (it being understood that a Guarantor may assert the
defense of final payment in full of the Guaranteed Obligations). 
 All waivers herein contained shall be without prejudice to the right of the
Administrative Agent at its option to proceed against any Loan Party or any other Person, whether by separate action or by joinder. 

Section 1.06 Agreement to Pay; Subordination of Subrogation Claims. In furtherance of the foregoing and not
in limitation of any other right that the Administrative Agent, any other Agent or any other Finance Party has at Law or in equity against any Guarantor by virtue hereof, upon the failure of any Other Loan Party to pay any Guaranteed Obligation when
and as the same shall become due, whether at maturity, by acceleration, after notice of prepayment or otherwise, each Guarantor hereby promises to and will forthwith pay, or cause to be paid, to the Administrative Agent, or any other Agent or other
Finance Party designated by the Administrative Agent in cash the amount of such unpaid Guaranteed Obligations. Upon payment by any Guarantor of any sums to the Administrative Agent any other Agent or any Finance Party as provided above, all
rights of such Guarantor against any Other Loan Party arising as a result thereof by way of right of subrogation, contribution, reimbursement, indemnity or otherwise shall (including, without limitation, in the case of any Guarantor, any rights of
such Guarantor arising under Article II) in all respects be subordinate and junior in right of payment to the prior payment in full in cash of all the Guaranteed Obligations (other than contingent indemnification
obligations). No failure on the part of any Other Loan Party or any other Person to make any payments in respect of any subrogation, contribution, reimbursement, indemnity or similar right (or any other payments required under applicable Law or
otherwise) shall in any respect limit the obligations and liabilities of any Guarantor with respect to its obligations hereunder. If any amount shall erroneously be paid to any Guarantor on account of such subrogation, contribution,
reimbursement indemnity or similar right, such amount shall be held in trust, as applicable, for the benefit of the Finance Parties, and shall forthwith be turned over to the Administrative Agent, in the exact form received by such Guarantor (duly
endorsed by such Guarantor to the Administrative Agent, if required) to be credited against the payment of matured Guaranteed Obligations in accordance with the terms of the Finance Documents.

 Section 1.07 Stay of Acceleration. If acceleration of the time for
payment of any amount payable by the Borrowers under or with respect to the Guaranteed Obligations is stayed upon the insolvency or bankruptcy of any Borrower, all such amounts otherwise subject to acceleration under the terms of the Credit
Agreement, the Notes, any Swap Agreement or any other agreement or instrument evidencing or securing the Guaranteed Obligations shall nonetheless be payable by the Guarantors hereunder, jointly and severally, forthwith on demand by the
Administrative Agent, in the manner provided in Section 1.01. 
 Section 1.08 No
Set-Off. No act or omission of any kind or at any time on the part of any Finance Party in respect of any matter whatsoever shall in any way affect or impair the rights of the Administrative Agent or any other Finance Party to enforce
any right, power or benefit under this Agreement, and no set-off, claim, reduction or diminution of any Guaranteed Obligation or any defense of any kind or nature which any Guarantor has or may have against any Borrower or any Finance Party shall be
available against the Administrative Agent or any other Finance Party in any suit or action brought by the Administrative Agent or any other Finance Party to enforce any right, power or benefit provided for by this Agreement; provided that
nothing herein shall prevent the assertion by any Guarantor of any such claim by separate suit or compulsory counterclaim. Nothing in this Agreement shall be construed as a waiver by any Guarantor of any rights or claims which it may have
against any Finance Party hereunder or otherwise, but any recovery upon such rights and claims shall be had from such Finance Party separately, it being the intent of this Agreement that each Guarantor shall be unconditionally, absolutely and
jointly and severally obligated to perform fully all its obligations, covenants and agreements hereunder for the benefit of each Finance Party. 

ARTICLE II 

INDEMNIFICATION, SUBROGATION AND CONTRIBUTION 

Section 2.01 Indemnity and Subrogation. In addition to all such rights of indemnity and subrogation as the
Guarantors may have under applicable Law (but subject to Section 1.06), the Borrowers agree that (i) in the event a payment shall be made by any Guarantor under this Agreement, the Borrowers shall indemnify such
Guarantor for the full amount of such payment and such Guarantor shall be subrogated to the rights of the person to whom such payment shall have been made to the extent of such payment and (ii) in the event any assets of any Guarantor shall be
sold pursuant to any Collateral Document to satisfy a claim of any Finance Party, the Borrowers shall indemnify such Guarantor in an amount equal to the greater of the book value or the fair market value of the assets so sold. 

Section 2.02 Contribution and Subrogation. Each Guarantor (a “Contributing Guarantor”) agrees (subject
to Section 1.06) that, in the event a payment shall be made by any other Guarantor under this Agreement or assets of any other Guarantor shall be sold pursuant to any Collateral Document to satisfy a claim of any Finance
Party and such other Guarantor (the “Claiming Guarantor”) shall not have been fully indemnified by the Borrowers as provided in Section 2.01, the Contributing Guarantor shall indemnify the Claiming
Guarantor in an amount equal to the amount of such payment or the greater of the book value or the fair market value of such assets, as the case may be, in each case multiplied by a fraction the numerator of which shall be the net worth of the
Contributing Guarantor on the date that the obligation(s) supporting such claim were incurred under this Agreement and the denominator of which shall be the aggregate net worth of all the Guarantors on such date (or, in the case of any Guarantor
becoming a party hereto pursuant to Section 5.10, the date of the Accession Agreement executed and delivered by such Guarantor). Any Contributing Guarantor making any payment to a Claiming Guarantor pursuant to this
Section 2.02 shall be subrogated to the rights of such Claiming Guarantor under Section 2.01 to the extent of such payment.

respective permitted successors and assigns, except that no Guarantor shall have the right to assign or transfer its rights or obligations hereunder or any interest herein or in the Collateral (and any such assignment or transfer shall be void)
except as expressly contemplated by this Agreement or the Credit Agreement. This Agreement shall be construed as a separate agreement with respect to each Guarantor and may be amended, restated, amended and restated, modified, supplemented,

Guarantor hereunder with the same force and effect as if originally named as a Guarantor hereunder by executing an Accession Agreement and counterpart hereof and delivering the same to the Administrative Agent. The execution and delivery of any such
instrument shall not require the consent of any other Guarantor or other parties hereunder. The rights and obligations of each Guarantor or other party hereunder shall remain in full force and effect notwithstanding the addition of any new Guarantor
as a party to this Agreement.

or in any way alter or modify, any obligation or liability of any Grantor with respect to or arising out of the Article 9 Collateral. 
 (d)
Each Grantor hereby further authorizes the Collateral Agent (after prior review by MKS) to file with the USPTO or the USCO (or any successor office) such documents as may be necessary or advisable for the purpose of perfecting, confirming,
continuing, enforcing or protecting the Security Interest in United States registered and applied for Intellectual Property of each Grantor in which a security interest has been granted by each Grantor, without the signature of any Grantor, and
naming any Grantor or the Grantor as debtors and the Collateral Agent as secured party. 
 Section 3.02 Representations and Warranties
Relating to Article 9 Collateral. Each Grantor represents and warrants to the Collateral Agent and the Secured Parties that: 
 (a)
Subject to Liens permitted by Section 7.02 of the Credit Agreement, such Grantor has good and valid rights in and title to the Article 9 Collateral with respect to which it has purported to grant a Security Interest hereunder and has full power and
authority to grant to the Collateral Agent the Security Interest in such Article 9 Collateral pursuant hereto and to execute, deliver and perform its obligations in accordance with the terms of this Agreement, without the consent or approval of any

material to the business of the Grantors, taken as a whole) in which a security interest may be perfected upon the receipt and recording of the relevant Grants of Security Interest with the United States Patent and Trademark Office and the United
States Copyright Office, as applicable, within the three month period (commencing as of the date hereof) pursuant to 35 U.S.C. § 261 or 15 U.S.C. § 1060 or the one month period (commencing as of the date hereof) pursuant to 17 U.S.C.
§ 205. The Security Interest is and shall be prior to any other Lien on any of the Article 9 Collateral, other than (i) any non-consensual Lien that is expressly permitted pursuant to Section 7.02 of the Credit Agreement and has priority as a
matter of law and (ii) any other Lien that is expressly permitted pursuant to Section 7.02 of the Credit Agreement. 
 (c) The Perfection

registered Trademarks (and Trademarks for which United States registration applications are pending) and United States registered Copyrights, respectively, have been delivered to the Collateral Agent for recording by the USPTO and the USCO pursuant
to 35 U.S.C. § 261, 15 U.S.C. § 1060 or 17 U.S.C. § 205 and the regulations thereunder, as applicable, (for the benefit of the Secured Parties) in respect of all Article 9 Collateral consisting of registrations and applications for
United States Patents, Trademarks and Copyrights. 
 (e) None of the Grantors has filed or consented to (i) the filing of any financing

Article 9 Collateral with the USPTO or the USCO, or (iii) any assignment in which any Grantor assigns any Article 9 Collateral or any security agreement or similar instrument covering any Article 9 Collateral with any foreign governmental, municipal
or other office, which financing statement or analogous document, assignment, security agreement or similar instrument is still in effect, except, in each case, for Liens not prohibited pursuant to Section 7.02 of the Credit Agreement and
assignments not prohibited by the Credit Agreement.

 Section 3.03 Covenants. 

(a) Each Grantor agrees to promptly (and in any event within fifteen (15) days of such event, or such later date as the Collateral Agent may
agree in its reasonable discretion) notify the Collateral Agent of any change (i) in the legal name of any Grantor, (ii) in the identity or type of organization or corporate structure of any Grantor, (iii) in the jurisdiction of organization of any
Grantor, (iv) in the location of any Grantor under the UCC or (v) in the organizational identification number of any Grantor, if any, but solely to the extent such organizational identification number is required to be set forth on financing
statements under the UCC. Each Grantor shall take all actions reasonably satisfactory to the Collateral Agent to the extent necessary to maintain the security interests (and the priority thereof) of the Collateral Agent in the Collateral intended to
be granted hereby fully perfected and in full force and effect. 
 (b) Each Grantor shall, at its own expense, take any and all commercially
reasonable actions necessary to defend the Security Interest of the Collateral Agent in the Article 9 Collateral and the priority thereof against any Lien prohibited pursuant to Section 7.02 of the Credit Agreement; provided, that, nothing in
this Agreement shall prevent any Grantor from discontinuing the operation or maintenance of any of its assets or properties if such discontinuance is (x) determined by such Grantor to be desirable in the conduct of its business and (y) permitted by
the Credit Agreement. 
 (c) Each Grantor agrees, at its own expense, to execute, acknowledge, deliver and cause to be duly filed all such
further instruments and documents and take all such actions as the Collateral Agent may from time to time reasonably request to better assure, preserve, protect and perfect the Security Interest and the rights and remedies created hereby, including
the payment of any fees and taxes required in connection with the execution and delivery of this Agreement, the granting of the Security Interest and the filing of any financing statements or other documents in connection herewith or therewith. If
any amounts payable under or in connection with any of the Article 9 Collateral shall be or become evidenced by any promissory notes, other instruments or debt securities, such notes, instruments or debt securities shall be delivered to the
Collateral Agent to the extent required pursuant to Section 2.02. Without limiting the generality of the foregoing, each Grantor shall make, execute, endorse, acknowledge, file or refile and/or deliver to the Collateral Agent from time
to time upon reasonable request by the Collateral Agent such confirmatory assignments, supplements, additional security agreements, conveyances, financing statements, transfer endorsements, powers of attorney, certificates, reports and other
assurances or instruments as the Collateral Agent shall reasonably request. If an Event of Default has occurred and is continuing, the Collateral Agent may institute and maintain, in its own name or in the name of any Grantor, such suits and
proceedings as the Collateral Agent may be advised by counsel shall be necessary or expedient to prevent any impairment of the security interest in or the perfection thereof in the Collateral. All of the foregoing shall be at the sole cost and
expense of the Grantors. 
 (d) At its option, the Collateral Agent may discharge past due taxes, assessments, charges, fees, Liens,
security interests or other encumbrances (other than with respect to any of the foregoing that are subject to dispute) at any time levied or placed on the Article 9 Collateral and prohibited pursuant to Section 7.02 of the Credit Agreement, and may
pay for the maintenance and preservation of the Article 9 Collateral to the extent any Grantor fails to do so as required by the Credit Agreement or any other Loan Document and within a reasonable period of time after the Collateral Agent has
requested that it do so, and each Grantor jointly and severally agrees to reimburse the Collateral Agent within ten (10) Business Days (or such later date as may be agreed to by the Collateral Agent in its sole discretion) after demand for any
payment made or any reasonable expense incurred by the Collateral Agent pursuant to the foregoing authorization. Nothing in this paragraph shall be interpreted as excusing any Grantor from the performance of, or imposing any obligation on the
Collateral Agent or any Secured Party to cure or perform, any covenants or other promises of any Grantor with respect to taxes, assessments, charges, fees, Liens, security interests or other encumbrances and maintenance as set forth herein or in the
other Loan Documents.

 (e) Intellectual Property Covenants. 

(i) Notwithstanding any other provision of this Agreement, nothing in this Agreement or any other Loan Document prevents or
shall be deemed to prevent any Grantor from disposing of, discontinuing the use or maintenance of, failing to pursue, or otherwise allowing to lapse, expire, terminate or be put into the public domain, any of its Intellectual Property to the extent
not prohibited by the Credit Agreement if such Grantor determines in its reasonable business judgment that such discontinuance is desirable in the conduct of its business. 

(ii) No later than the subsequent Quarterly Update Date (or such later date as may be agreed to by the Collateral Agent in its
sole discretion), MKS shall provide a list of any additional registrations of or applications for Intellectual Property of all Grantors with the USPTO and no later than within the time periods set forth in Section 6.09 of the Credit Agreement MKS
shall provide a list of any additional registrations of or applications for Intellectual Property of all Grantors with the USCO, in each case not previously disclosed to the Collateral Agent including such information as is necessary for such
Grantor to make appropriate filings in the USPTO and USCO. The provisions hereof shall automatically apply to such Intellectual Property as if such would have constituted Article 9 Collateral at the time of execution hereof and be subject to the
Security Interest without further action by any party. Each Grantor shall promptly provide to the Collateral Agent confirmation of the attachment of the Security Interest to such Intellectual Property by execution of an instrument in form reasonably
acceptable to the Collateral Agent and the filing of any instruments or statements as shall be reasonably necessary to create, preserve, protect or perfect the Collateral Agent’s Security Interest in such Intellectual Property. 

(f) If the Grantors shall at any time hold or acquire any Commercial Tort Claims with a value reasonably estimated by such Grantor to exceed
$5,000,000 for which this clause has not been satisfied and for which a complaint in a court of competent jurisdiction has been filed, such Grantor shall within the time periods set forth in Section 6.09 of the Credit Agreement notify the Collateral
Agent thereof in a writing signed by such Grantor including a summary description of such claim and grant to the Collateral Agent, for the benefit of the Secured Parties, in such writing a security interest therein and in the proceeds thereof, all
upon the terms of this Agreement. 
 (g) In the event that the proceeds of any insurance claim are paid to any Grantor after the Collateral
Agent has exercised its right to foreclose after an Event of Default, such proceeds shall be held in trust for the benefit of the Collateral Agent and immediately after receipt thereof shall be paid to the Collateral Agent for application in
accordance with Section 4.02. 
 ARTICLE IV 

Remedies 
 Section
4.01 Remedies Upon Default. Upon the occurrence and during the continuance of an Event of Default, the Collateral Agent shall have the right to exercise any and all rights afforded to a secured party with respect to the Secured Obligations,
including the Guarantees, under the UCC or other applicable Law and also may (i) require each Grantor to, and each Grantor agrees that it will at its expense and upon request of the Collateral Agent promptly, assemble all or part of the Collateral
as directed by the Collateral Agent and make it available to the Collateral Agent at a place and time to be designated by the Collateral Agent that is reasonably convenient to both parties; (ii) occupy any premises owned or, to the extent lawful and
permitted, leased by any of the Grantors where the Collateral or any part thereof is assembled or located for a reasonable period in order to effectuate its rights and remedies hereunder or under Law, without obligation to such Grantor in respect of
such 

  
 -13- 







Table of Contents


 
occupation; provided that the Collateral Agent shall provide the applicable Grantor with notice thereof prior to or promptly after such occupancy; (iii) exercise any and all rights and
remedies of any of the Grantors under or in connection with the Collateral, or otherwise in respect of the Collateral; and (iv) subject to the mandatory requirements of applicable Law and the notice requirements described below, sell or otherwise
dispose of all or any part of the Collateral securing the Secured Obligations at a public or private sale or at any broker’s board or on any securities exchange, for cash, upon credit or for future delivery as the Collateral Agent shall deem
appropriate. Each Grantor acknowledges and recognizes that (a) the Collateral Agent may be unable to effect a public sale of all or a part of the Collateral consisting of securities by reason of certain prohibitions contained in the Securities Act
of 1933, 15 U.S.C. §77, (as amended and in effect, the “Securities Act”) or the securities laws of various states (the “Blue Sky Laws”), but may be compelled to resort to one or more private sales to a
restricted group of purchasers who will be obliged to agree, among other things, to acquire such securities for their own account, for investment and not with a view to the distribution or resale thereof, (b) private sales so made may be at prices
and upon other terms less favorable to the seller than if such securities were sold at public sales, (c) neither the Collateral Agent nor any other Secured Party has any obligation to delay sale of any of the Collateral for the period of time
necessary to permit such securities to be registered for public sale under the Securities Act or the Blue Sky Laws, and (d) private sales made under the foregoing circumstances shall not, for the reason of any or all of such circumstances, be deemed
to have been made in a commercially unreasonable manner. To the maximum extent permitted by Law, each Grantor hereby waives any claim against any Secured Party arising because the price at which any Collateral may have been sold at a private sale
was less than the price that might have been obtained at a public sale, even if the Collateral Agent accepts the first offer received and does not offer such Collateral to more than one offeree. Upon consummation of any such sale the Collateral
Agent shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold. Each such purchaser at any sale of Collateral shall hold the property sold absolutely, free from any claim or right on the part
of any Grantor, and each Grantor hereby waives (to the extent permitted by applicable Law) all rights of redemption, stay and appraisal which such Grantor now has or may at any time in the future have under any rule of law or statute now existing or
hereafter enacted. The Collateral Agent shall be authorized at any such sale of securities (if it deems it advisable to do so) to restrict the prospective bidders or purchasers to Persons who will represent and agree that they are purchasing such
securities for their own account for investment and not with a view to the distribution or sale thereof, and upon consummation of any such sale the Collateral Agent shall have the right to assign, transfer and deliver to the purchaser or purchasers
thereof the securities so sold. 
 The Collateral Agent shall give the applicable Grantors ten (10) days’ written notice (which each
Grantor agrees is reasonable notice within the meaning of Section 9-611 of the UCC or its equivalent in other jurisdictions) of the Collateral Agent’s intention to make any sale of Collateral. Such notice, in the case of a public sale, shall
state the time and place for such sale and, in the case of a sale at a broker’s board or on a securities exchange, shall state the board or exchange at which such sale is to be made and the day on which the Collateral, or portion thereof, will
first be offered for sale at such board or exchange. Any such public sale shall be held at such time or times within ordinary business hours and at such place or places as the Collateral Agent may fix and state in the notice (if any) of such sale.
At any such sale, the Collateral, or portion thereof, to be sold may be sold in one lot as an entirety or in separate parcels, as the Collateral Agent may (in its sole and absolute discretion) determine. The Collateral Agent shall not be obligated
to make any sale of any Collateral if it shall determine not to do so, regardless of the fact that notice of sale of such Collateral shall have been given. The Collateral Agent may, without notice or publication, adjourn any public or private sale
or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned. In case any sale of all or any
part of the Collateral is made on credit or for future delivery, the Collateral so sold may be retained by the Collateral Agent until the sale price is paid by the purchaser or purchasers thereof, but the Collateral Agent shall not


  
 -14- 







Table of Contents


 
incur any liability in case any such purchaser or purchasers shall fail to take up and pay for the Collateral so sold and, in case of any such failure, such Collateral may be sold again upon like
notice. At any public (or, to the extent permitted by Law, private) sale made pursuant to this Agreement, any Secured Party may bid for or purchase, free (to the extent permitted by Law) from any right of redemption, stay, valuation or
appraisal on the part of any Grantor (all said rights being also hereby waived and released to the extent permitted by Law), the Collateral or any part thereof offered for sale. As an alternative to exercising the power of sale herein conferred
upon it, the Collateral Agent may, to the extent permitted by law, to the extent permitted by Law, proceed by a suit or suits at Law or in equity to foreclose this Agreement and to sell the Collateral or any portion thereof pursuant to a judgment or
decree of a court or courts having competent jurisdiction or pursuant to a proceeding by a court-appointed receiver. 
 Section 4.02
Application of Proceeds. After the exercise of remedies provided for in Section 8.02 of the Credit Agreement (or after the Loans have automatically become immediately due and payable), the Collateral Agent shall promptly apply the proceeds of
any collection or sale of Collateral, including any Collateral consisting of cash in accordance with Section 8.03 of the Credit Agreement. 

Upon any sale of Collateral by the Collateral Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding),
the receipt of the Collateral Agent or the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold and such purchaser or purchasers shall not be obligated to see to the application of any part
of the purchase money paid over to the Collateral Agent or such officer or be answerable in any way for the misapplication thereof. 
 The
Collateral Agent shall have no liability to any of the Secured Parties for actions taken in reliance on information supplied to it as to the amounts of unpaid principal and interest and other amounts outstanding with respect to the Secured
Obligations; provided that nothing in this sentence shall prevent any Grantor from contesting any amounts claimed by any Secured Party in any information so supplied. All distributions made by the Collateral Agent pursuant to this
Section 4.02 shall be (subject to any decree of any court of competent jurisdiction) final (absent manifest error), and the Collateral Agent shall have no duty to inquire as to the application by the Administrative Agent of any amounts
distributed to it. 
 Section 4.03 Grant of License to Use Intellectual Property. For the exclusive purpose of enabling the
Collateral Agent to exercise rights and remedies under this Agreement at such time as the Collateral Agent shall be lawfully entitled to exercise such rights and remedies at any time after and during the continuance of an Event of Default, each
Grantor hereby grants to the Collateral Agent a non-exclusive, royalty-free, limited license to use, license or sublicense any of the Intellectual Property now owned or hereafter acquired by such Grantor, and wherever the same may be located, and
including in such license access to all media in which such licensed items may be recorded or stored and to all computer software and programs used for the compilation or printout thereof; provided, that all of the foregoing rights of the
Collateral Agent to use such licenses, sublicenses and other rights, and (to the extent permitted by the terms of such licenses and sublicenses) all licenses and sublicenses granted thereunder, shall expire immediately upon the termination or cure
of all Events of Default and shall be exercised by the Collateral Agent solely during the continuance of an Event of Default; and provided, further, that nothing in this Section 4.03 shall require Grantors to grant any license
that is prohibited by any rule of law, statute or regulation, or is prohibited by, or constitutes a breach or default under or results in the termination of any contract, license, agreement, instrument or other document evidencing, giving rise to or
theretofore granted, to the extent permitted by the Credit Agreement, with respect to such property or otherwise unreasonably prejudices the value thereof to the relevant Grantor; provided, further, that such licenses granted hereunder
with respect to Trademarks material to the business of such Grantor shall be subject to restrictions, including, without limitation restrictions as to goods or services associated 

  
 -15-

with such Trademarks and the maintenance of quality standards with respect to the goods and services on which such Trademarks are used, sufficient to preserve the validity and value of such
Trademarks. Upon the occurrence and during the continuance of an Event of Default, the Collateral Agent may also exercise the rights afforded under Section 4.01 of this Agreement with respect to Intellectual Property contained in the
Article 9 Collateral. 
 ARTICLE V 

Subordination 

Section 5.01 Subordination. 

(a) Notwithstanding any provision of this Agreement to the contrary, all rights of the Grantors of indemnity, contribution or subrogation
under applicable Law or otherwise, arising under this Agreement or the Guaranty Agreement, shall be fully subordinated to the payment in full in cash of the Secured Obligations. No failure on the part of any Borrower or any Grantor to make the
indemnity, contribution or subrogation payments required under applicable Law or otherwise shall in any respect limit the obligations and liabilities of any Grantor with respect to its obligations hereunder, and each Grantor shall remain liable for
the full amount of the obligations of such Grantor hereunder. 
 (b) Each Grantor hereby agrees that upon the occurrence and during the
continuance of an Event of Default and after notice from the Collateral Agent, all Indebtedness owed to it by any other Grantor shall be fully subordinated to the payment in full in cash of the Secured Obligations. 

(c) If any amount shall erroneously be paid to any Borrower or any other Grantor on account of (i) such subrogation, contribution,
reimbursement, indemnity or similar right or (ii) any such subordinated indebtedness of any Borrower or any other Grantor, such amount shall be held in trust for the benefit of the Secured Parties and shall forthwith be paid to the Collateral Agent
to be credited against the payment of the Secured Obligations, whether matured or unmatured, in accordance with the terms of the Credit Agreement and the other Loan Documents. 

(d) Subject to the foregoing, to the extent that any Grantor (other than a Borrower) shall, under this Agreement or the Credit Agreement as a
joint and several obligor, repay any of the Secured Obligations (an “Accommodation Payment”), then the Grantor making such Accommodation Payment shall be entitled to contribution and indemnification from, and be reimbursed by, each
of the other Grantors in an amount equal to a fraction of such Accommodation Payment, the numerator of which fraction is such other Grantor’s Allocable Amount and the denominator of which is the sum of the Allocable Amounts of all of the
Grantors. As of any date of determination, the “Allocable Amount” of each Grantor shall be equal to the maximum amount of liability for Accommodation Payments which could be asserted against such Grantor hereunder and under the
Credit Agreement without (a) rendering such Grantor “insolvent” within the meaning of Section 101 (31) of the Bankruptcy Code, Section 2 of the Uniform Fraudulent Transfer Act (“UFTA”) or Section 2 of the Uniform
Fraudulent Conveyance Act (“UFCA”), (b) leaving such Grantor with unreasonably small capital or assets, within the meaning of Section 548 of the Bankruptcy Code, Section 4 of the UFTA, or Section 5 of the UFCA, or (c) leaving such
Grantor unable to pay its debts as they become due within the meaning of Section 548 of the Bankruptcy Code or Section 4 of the UFTA, or Section 5 of the UFCA. 

(e) Anything contained in this Agreement to the contrary notwithstanding, the obligations of each Grantor hereunder (other than a Borrower)
shall be limited to a maximum aggregate amount equal to the greatest amount that would not render such Grantor’s obligations hereunder subject to avoidance as a fraudulent transfer or conveyance under Section 548 of Title 11 of the United
States

Code or any provisions of applicable state law (collectively, the “Fraudulent Transfer Laws”), in each case after giving effect to all other liabilities of such Grantor,
contingent or otherwise, that are relevant under the Fraudulent Transfer Laws (specifically excluding, however, any liabilities of such Grantor (i) in respect of intercompany indebtedness to any Borrower or any of its Affiliates to the extent that
such indebtedness (A) would be discharged or would be subject to a right of set-off in an amount equal to the amount paid by such Grantor hereunder or (B) has been pledged to, and is enforceable by, the Collateral Agent on behalf of the Secured
Parties and (ii) under any guaranty of Indebtedness subordinated in right of payment to the Secured Obligations which guaranty contains a limitation as to a maximum amount similar to that set forth in this paragraph pursuant to which the liability
of such Grantor hereunder is included in the liabilities taken into account in determining such maximum amount) and after giving effect as assets of such Grantor to the value (as determined under the applicable provisions of the Fraudulent Transfer
Laws) of any rights to subrogation, contribution, reimbursement, indemnity or similar rights of such Grantor pursuant to (i) applicable Law or (ii) any agreement providing for an equitable allocation among such Grantor and other Affiliates of such
Borrower of obligations arising under guaranties by such parties. If any Grantor’s (other than a Borrower’s) liability hereunder is limited pursuant to this paragraph to an amount that is less than the total amount of the Secured
Obligations, then it is understood and agreed that the portion of the Secured Obligations for which such Grantor is liable hereunder shall be the last portion of the Secured Obligations to be repaid. 

ARTICLE VI 

Miscellaneous 

Section 6.01 Notices. All communications and notices hereunder shall (except as otherwise expressly permitted herein) be in writing and
given as provided in Section 10.02 of the Credit Agreement. All communications and notices hereunder to MKS or any other Grantor shall be given to it in care of MKS as provided in Section 10.02 of the Credit Agreement. 

Section 6.02 Waivers; Amendment. 

(a) No failure or delay by any Secured Party in exercising any right, remedy, power or privilege hereunder or under any other Loan Document
shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, remedy, power or privilege, or any abandonment or discontinuance of steps to enforce such rights, remedies, powers or privileges 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 of the Secured Parties herein provided, and provided under each other Loan Document, are cumulative and are
not exclusive of any rights, remedies, powers and privileges provided by Law. No waiver of any provision of this Agreement or consent to any departure by any Grantor therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section 6.02, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or
the issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether any Secured Party may have had notice or knowledge of such Default at the time. 

(b) Except as otherwise provided in Section 6.12, neither this Agreement nor any provision hereof may be waived, amended or modified
except pursuant to an agreement or agreements in writing entered into by the Collateral Agent and the Grantor or Grantors with respect to which such waiver, amendment or modification is to apply, subject to any consent required in accordance with
Section 10.01 of the Credit Agreement.

Document, or any investigation made by or on behalf of the Collateral Agent or any other Secured Party. All amounts due under this Section 6.03 shall be payable within ten (10) days of written demand therefor (or such later date as may

other Loan Documents and in the certificates or other instruments prepared or delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the Secured Parties and shall survive
the execution and delivery of the Loan Documents, the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any Secured Party or on its behalf and notwithstanding that any Secured Party may have had
notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended under the Credit Agreement, and shall continue in full force and effect as long as this Agreement has not been terminated or released
pursuant to Section 6.11 below. 
 Section 6.06 Counterparts; Effectiveness; Several Agreement. This Agreement may be executed
in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Delivery by facsimile or other electronic communication of an executed counterpart (including

executed on behalf of such Grantor shall have been delivered to the Collateral Agent and a counterpart hereof shall have been executed on behalf of the Collateral Agent, and thereafter shall be binding upon such Grantor and the Collateral Agent and
their respective permitted successors and assigns, and shall inure to the benefit of such Grantor, the Collateral Agent and the other Secured Parties and their respective permitted successors and assigns, except that no Grantor shall have the right
to assign or transfer its rights or obligations hereunder or any interest herein or in the Collateral (and any such assignment or transfer shall be void) except as expressly contemplated by this Agreement or the Credit Agreement. This Agreement
shall be construed as a separate agreement with respect to each Grantor and may be amended, restated, amended and restated, modified, supplemented, waived or released with respect to any Grantor without the approval of any other Grantor and without
affecting the obligations of any other Grantor hereunder. 
 Section 6.07 Severability. If any provision of this Agreement is held to

Document, any agreement with respect to any of the Secured Obligations or any other agreement or instrument relating to any of the foregoing, (b) any change in the time, manner or place of payment of, or in any other term of, all or any of the
Secured Obligations, or any other amendment or waiver of or any consent to any departure from the Credit Agreement, any other Loan Document or any other agreement or instrument, (c) any exchange, release or non-perfection of any Lien on other
collateral, or any release or amendment or waiver of or consent under or departure from any guarantee, securing or guaranteeing all or any of the Secured Obligations or (d) any other circumstance that might otherwise constitute a defense available
to, or a discharge of, any Grantor in respect of the Secured Obligations or this Agreement. 
 Section 6.11 Termination or Release.

 (a) This Agreement, the Security Interest and all other security interests granted hereby shall terminate with respect to all Secured
Obligations and any Liens arising therefrom shall be automatically released upon a Discharge of Senior Credit Obligations. 
 (b) A
Subsidiary Party shall automatically be released from its obligations hereunder and the Security Interest in the Collateral of such Subsidiary Party shall be automatically released upon the consummation of any transaction permitted by the Credit
Agreement as a result of which such Subsidiary Party ceases to be a Subsidiary of a Borrower or ceases to be a Guarantor. 
 (c) Upon any
sale, transfer or disposition by any Grantor of any Collateral that is permitted under the Credit Agreement (other than a sale, transfer or disposition to another Loan Party), or upon the effectiveness of any written consent to the release of the
security interest granted hereby in any Collateral pursuant to Section 10.01 of the Credit Agreement or to the extent such Collateral is owned by a Grantor upon the release of such Grantor from its obligations hereunder or under the Guaranty
Agreement, in each case, the security interest in such Collateral shall be automatically released. The Collateral Agent shall enter into non-disturbance and similar agreement reasonably requested by any Grantor in connection with the licensing of
intellectual property permitted pursuant to the terms of the Credit Agreement. 
 (d) In connection with any termination or release pursuant

expense, all documents that such Grantor shall reasonably request to evidence such termination or release and shall perform such other actions reasonably requested by such Grantor to effect such
release, including delivery of certificates, securities and instruments. Any execution and delivery of documents pursuant to this Section 6.11 shall be without recourse to or warranty by the Collateral Agent (except as to the fact that
the Collateral Agent has not encumbered the released assets or any part thereof) and subject to the Collateral Agent’s receipt of a certification by MKS and applicable Grantor stating that such transaction is in compliance with the Credit
Agreement and the other Loan Documents and as to such other matters as the Collateral Agent may reasonably request. 
 Section 6.12
Additional Grantors. Subject to the provisions of Section 6.09 of the Credit Agreement, the Grantors shall cause each Loan Party (including, for the avoidance of doubt, any Restricted Subsidiary that is no longer an Excluded Subsidiary
or an Excluded Tax Subsidiary) which, from time to time, after the date hereof shall be required to pledge any assets to the Collateral Agent for the benefit of the Secured Parties pursuant to the provisions of the Credit Agreement, to execute and
deliver to the Collateral Agent (i) a joinder agreement in form and substance reasonably acceptable to the Collateral Agent and (ii) a Perfection Certificate, in each case, within the time periods specified in Section 6.09 of the Credit Agreement
(or such later date as may be agreed to by the Collateral Agent in its sole discretion) after the date on which it was acquired, created or otherwise required to become a Grantor hereunder. Upon execution and delivery by the Collateral Agent
and a Restricted Subsidiary of a supplement to the Security Agreement in form and substance reasonably satisfactory to the Collateral Agent, such Restricted Subsidiary shall become a Grantor hereunder with the same force and effect as if originally
named as a Grantor herein. The execution and delivery of any such instrument shall not require the consent of any other Grantor hereunder. The rights and obligations of each Grantor hereunder shall remain in full force and effect
notwithstanding the addition of any new Grantor as a party to this Agreement. 
 Section 6.13 Collateral Agent Appointed
Attorney-in-Fact. Each Grantor hereby appoints the Collateral Agent (and all officers, employees or agents designated by the Collateral Agent) as such Grantor’s true and lawful agent (and attorney-in-fact) of such Grantor for the purpose of
carrying out the provisions of this Agreement and taking any action and executing any instrument that the Collateral Agent may deem necessary or advisable to accomplish the purposes hereof at any time after and during the continuance of an Event of
Default, which appointment is irrevocable (except as provided in Section 6.11) and coupled with an interest. Without limiting the generality of the foregoing, the Collateral Agent shall have the right, upon the occurrence and during the
continuance of an Event of Default and notice by the Collateral Agent to the applicable Grantor of the Collateral Agent’s intent to exercise such rights, with full power of substitution either in the Collateral Agent’s name or in the name
of such Grantor (a) to receive, endorse, assign and/or deliver any and all notes, acceptances, checks, drafts, money orders or other evidences of payment relating to the Collateral or any part thereof; (b) to demand, collect, receive payment of,
give receipt for and give discharges and releases of all or any of the Collateral or Mortgaged Property; (c) to sign the name of any Grantor on any invoice or bill of lading relating to any of the Collateral or Mortgaged Property; (d) to send
verifications of accounts receivable to any Account Debtor; (e) to commence and prosecute any and all suits, actions or proceedings at Law or in equity in any court of competent jurisdiction to collect or otherwise realize on all or any of the
Collateral or Mortgaged Property or to enforce any rights in respect of any Collateral or Mortgaged Property; (f) to settle, compromise, compound, adjust or defend any actions, suits or proceedings relating to all or any of the Collateral or
Mortgaged Property; (g) to notify, or to require any Grantor to notify, Account Debtors to make payment directly to the Collateral Agent; (h) to make, settle and adjust claims in respect of Article 9 Collateral or Mortgaged Property under policies
of insurance, endorsing the name of such Grantor on any check, draft, instrument or other item of payment for the proceeds of such policies of insurance; (i) to make all determinations and decisions with respect thereto; (j) to obtain or maintain
the policies of insurance required by Section 6.05 of the Credit Agreement or paying any premium in whole or in part

relating thereto; and (k) to use, sell, assign, transfer, pledge, make any agreement with respect to or otherwise deal with all or any of the Collateral or Mortgaged Property, and to do all other
acts and things necessary to carry out the purposes of this Agreement, as fully and completely as though the Collateral Agent were the absolute owner of the Collateral or Mortgaged Property for all purposes; provided that nothing herein
contained shall be construed as requiring or obligating the Collateral Agent to make any commitment or to make any inquiry as to the nature or sufficiency of any payment received by the Collateral Agent, or to present or file any claim or notice, or
to take any action with respect to the Collateral or Mortgaged Property or any part thereof or the moneys due or to become due in respect thereof or any property covered thereby. The Collateral Agent and the other Secured Parties shall be
accountable only for amounts actually received as a result of the exercise of the powers granted to them herein, and neither they nor their officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act
hereunder, except for their own gross negligence, bad faith, or willful misconduct or that of any of their Affiliates, directors, officers, employees, counsel, agents or attorneys-in-fact, in each case, as determined by a final non-appealable
judgment of a court of competent jurisdiction. All sums disbursed by the Collateral Agent in connection with this paragraph, including reasonable and documented out-of-pocket attorneys’ fees, court costs, expenses and other charges relating
thereto, shall be payable, within 10 days of demand (or such later date as may be agreed to by the Collateral Agent in its sole discretion), by the Grantors to the Collateral Agent and shall be additional Secured Obligations secured hereby. 

Section 6.14 General Authority of the Collateral Agent. By acceptance of the benefits of this Agreement and any other Collateral
Documents, each Secured Party (whether or not a signatory hereto) shall be deemed irrevocably (a) to consent to the appointment of the Collateral Agent as its agent hereunder and under such other Collateral Documents, (b) to confirm that the
Collateral Agent shall have the authority to act as the exclusive agent of such Secured Party for the enforcement of any provisions of this Agreement and such other Collateral Documents against any Grantor, the exercise of remedies hereunder or
thereunder and the giving or withholding of any consent or approval hereunder or thereunder relating to any Collateral or any Grantor’s obligations with respect thereto, (c) to agree that it shall not take any action to enforce any provisions
of this Agreement or any other Collateral Document against any Grantor, to exercise any remedy hereunder or thereunder or to give any consents or approvals hereunder or thereunder except as expressly provided in this Agreement or any other
Collateral Document and (d) to agree to be bound by the terms of this Agreement and any other Collateral Documents. 
 Section 6.15
Reasonable Care. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Collateral Agent shall have no duty as to any Collateral, as to ascertaining or taking
action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not any Secured Party has or is deemed to have knowledge of such matters, or as to the taking of any necessary steps to
preserve rights against any parties or any other rights pertaining to any Collateral. The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral
is accorded treatment substantially equal to that which it accords its own property. 
 Section 6.16 Delegation; Limitation. The
Collateral Agent may execute any of the powers granted under this Agreement or the Mortgages and perform any duty hereunder either directly or by or through agents or attorneys-in-fact, and shall not be responsible for the gross negligence or
willful misconduct of any agents or attorneys-in-fact selected by it with reasonable care and without gross negligence or willful misconduct. 

Section 6.17 Reinstatement. The obligations of the Grantors under this Agreement shall be automatically reinstated if and to the
extent that for any reason any payment by or on behalf of a

Borrower or other Loan Party in respect of the Secured Obligations is rescinded or must be otherwise restored by any holder of any of the Secured Obligations, whether as a result of any
proceedings in bankruptcy or reorganization or otherwise. 
 Section 6.18 Miscellaneous. The Collateral Agent shall not be
deemed to have actual, constructive, direct or indirect notice or knowledge of the occurrence of any Event of Default unless and until the Collateral Agent shall have received a notice of Event of Default or a notice from the Grantor or the Secured
Parties to the Collateral Agent in its capacity as Collateral Agent indicating that an Event of Default has occurred. 
 Section 6.19
Intercreditor Matters.
 (a) Reference is made to the ABL Intercreditor Agreement, dated as of the date hereof (as amended,
supplemented, amended and restated or otherwise modified and in effect from time to time, the “Intercreditor Agreement”), among Deutsche Bank AG New York Branch, as ABL Agent for the ABL Secured Parties referred to therein, Barclays
Bank PLC, as Term Loan Agent for the Term Loan Secured Parties referred to therein, each Additional Debt Agent for the Additional Debt Secured Parties referred to therein, MKS Instruments, Inc. and the other Grantors party thereto. Each Person that
is secured hereunder, by accepting the benefits of the security provided hereby, (i) consents (or is deemed to consent), to the subordination of Liens provided for in the Intercreditor Agreement, (ii) agrees (or is deemed to agree) that it will be
bound by, and will take no actions contrary to, the provisions of the Intercreditor Agreement, and (iii) authorizes (or is deemed to authorize) the Administrative Agent and the Collateral Agent to, on behalf of such Person, enter into, and perform
under, the Intercreditor Agreement as “ABL Agent”, “Term Loan Agent” or “Additional Debt Agent”. Notwithstanding any other provision contained herein, this Agreement, the Liens created hereby and the rights, remedies,
duties and obligations provided for herein are subject in all respects to the provisions of the Intercreditor Agreement. In the event of any conflict or inconsistency between the provisions of this Agreement and the Intercreditor Agreement, the
provisions of the Intercreditor Agreement shall control. 
 (b) Notwithstanding any provision of any Loan Document to the contrary, for
purposes of any determination relating to the CF Debt Priority Collateral (as defined in the Intercreditor Agreement) as to which the Collateral Agent is granted discretion hereunder or under any other Loan Document, the Collateral Agent shall be
deemed to have agreed and accepted any determination in respect thereof by the Controlling CF Debt Agent (as defined in the Intercreditor Agreement) under the CF Debt Facility. 

(c) Notwithstanding anything to the contrary contained in this Agreement or any other Loan Document, to the extent the provisions of this
Agreement (or any other Collateral Documents) require the delivery of, or control over, CF Debt Priority Collateral to be granted to the Collateral Agent at any time prior to the discharge of obligations under the CF Debt Facility, then delivery of
such CF Debt Priority Collateral (or control with respect thereto) shall instead be made to the Controlling CF Debt Agent (as defined in the Intercreditor Agreement), to be held in accordance with the CF Debt Documents (as defined in the
Intercreditor Agreement) and the Intercreditor Agreement, each applicable Grantor’s obligations hereunder or in any other Loan Document (including the representations and warranties made by it hereunder and in the other Loan Documents) with
respect to such delivery shall be deemed satisfied by the delivery to the Controlling CF Debt Agent (as defined in the Intercreditor Agreement), acting as a gratuitous bailee of the Collateral Agent. Furthermore, at all times prior to the discharge
of the Obligations under the CF Debt Facility, the Collateral Agent is authorized by the parties hereto to effect transfers of such Collateral at any time in its possession (and any “control” or similar agreements with respect to such
Collateral) to the Controlling CF Debt Agent (as defined in the Intercreditor Agreement).

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 







Table of Contents



	 	(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.

[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) DEUTSCHE BANK AG NEW YORK BRANCH.,
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
April 29, 2016 (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 assumed 



  
 Exhibit N-1-1 







Table of Contents



	 	
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. In entering upon or into
the Leased Premises, Administrative Agent hereby agrees to indemnify, defend and hold Landlord harmless from and against any and all claims, judgments, liabilities, costs and expenses incurred by Landlord caused solely by Administrative Agent’s
entering upon or into the Leased Premises and inspection and/or removing of the Collateral from the Leased Premises. 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. In the event the Administrative Agent fails to
remove the Collateral prior to the expiration of the Disposition Period, Administrative Agent’s and Credit Parties’ interests in the Collateral will be deemed abandoned and Landlord may take possession of and dispose of Collateral in its
sole discretion at Administrative Agent’s and Credit Parties’ cost. 

  

	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:

	5.	This agreement and waiver shall inure to the benefit of the Administrative Agent, each of the Credit Parties and the Tenant, and their respective successors and assigns, and shall be binding upon the Landlord, its
heirs, assigns, representatives, and successors. The Administrative Agent may, without affecting the validity of this agreement and waiver, extend the maturity of, or otherwise modify, any indebtedness secured by the Collateral, or the
performance of any of the terms and conditions of any loan agreement or other documents evidencing the pledge to the Administrative Agent on behalf of the Credit Parties of the Collateral, without the consent of the Landlord and without giving
notice thereof to Landlord. 

  

	6.	The terms of this agreement and waiver are severable. If any of the terms and conditions hereof shall, for any 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, terms and conditions hereof are ambiguous or inconsistent, or conflict with any of the terms and
provisions of the Lease, any amendments thereto, or any documents executed in connection therewith, the provisions, terms and conditions of this agreement and waiver shall control. 


 

	7.	This agreement and waiver may not be amended or waived except by an instrument in writing signed by the Administrative Agent, the Landlord, and the Tenant. This agreement and waiver shall be governed by, and construed
in accordance with, the laws of the State of New York. Delivery of an executed signature page of this agreement and waiver by facsimile or electronic transmission shall be binding on the Landlord as if the original of such transmission had been
delivered to the Administrative Agent.

	 	Re:	The locations listed on Exhibit A attached hereto (collectively and individually, the “Premises”) 


[Grantor], a
[                ] [corporation][limited liability company] (the “Client”) has executed and delivered to DEUTSCHE
BANK AG NEW YORK BRANCH., as administrative agent and collateral agent (in such capacity and together with any successor acting in such capacity, the “Administrative Agent”) for its own benefit and for the benefit of certain other
lenders and secured parties, that certain ABL Security Agreement dated as of April 29, 2016 (as may be amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Security Agreement”),
pursuant to which the Client has pledged and granted to the Administrative Agent a continuing general lien (subject to certain exceptions) upon, and security interest in, among other things, the Client’s present and future merchandise,
inventory and other products (herein “Inventory”), including all Inventory now or hereafter held by you and which may be shipped through or stored with you from time to time in the future pursuant to the [Warehousing and Services
Agreement] dated as of [                    ] between you and Client (the “Warehouse Agreement”). 

1. Until you have received written notification from the Administrative Agent that it intends to foreclose on the Inventory (an “Agent
Notice”), you may continue to issue all receipts and/or bills of lading covering the Inventory in your possession from time to time in the Client’s name, and to release such Inventory pursuant to your agreements with, and upon the
instructions of, the Client. If you receive an Agent Notice from the Administrative Agent, you agree to (x) hold all Inventory subject only to the Administrative Agent’s written instructions and (y) give access to such Inventory and release the
same to the Administrative Agent or its designee on demand, or ship same as directed by the Administrative Agent on demand at the expense of the Administrative Agent, in each case upon the written instructions of the Administrative Agent. You agree
that you will not hinder or delay the Administrative Agent in enforcing its rights in and to such Inventory. 
 2. You hereby acknowledge
that you are not currently holding the Client’s Inventory for or on behalf of any other person other than the Client. 
 3. Except as
otherwise provided herein, all of your charges of any nature whatsoever shall continue to be charged to and paid by the Client and the Administrative Agent shall not be directly or indirectly liable or responsible for any of said charges whether due
or to become due. However, the Administrative Agent agrees to be liable to you for payment of (a) contractual charges that accrue under the Warehouse Agreement from and after the date that Administrative Agent gives you an Agent Notice directing you
to hold Inventory exclusively for the Administrative Agent for further disposition by the Administrative Agent and/or (b) charges for shipment of Inventory to any person pursuant to Administrative Agent’s written instructions, provided,
however, that in the event that any amounts shall be owing to you 

  
 Exhibit N-2-1 







Table of Contents


 
by the Client in respect of any Inventory located on the Premises, you will not be required to yield possession of any such Inventory to the Administrative Agent until such time as all reasonable
and customary amounts owing to you not to exceed an amount equal to two (2) months’ fees have been satisfied in full. 
 4. You hereby
subordinate any lien or other secured interest, whether express, implied, contractual, quasi-statutory or otherwise, and all claims and demands of every kind which you may now or hereafter have in, on or against the Inventory to the liens and
security interests, such subordination to be effective as of the later of (a) the effective date of the Warehouse Agreement or (b) the date of the Security Agreement, regardless of the time or order of attachment or perfection of such liens and
security interests, it being intended that the liens and security interests in Inventory in favor of the Administrative Agent shall at all times during the term of this agreement be prior and superior to any liens and security interests in your
favor. 
 5. The arrangement and instructions outlined herein shall automatically terminate when the Client’s obligations to the
Administrative Agent under the Security Agreement (other than contingent indemnification obligations) are paid in full and any commitment to lend under the Credit Agreement has terminated. 

6. The foregoing shall be binding upon the parties hereto and their successors and assigns, and shall inure to the benefit of the
Administrative Agent and its successors and assigns. 
 7. The Client agrees that you shall have no liability to the Client if you comply
with any of the Administrative Agent’s written directions as described in this agreement. The Client further agrees that it will continue to pay, as and when required under and pursuant to the Warehouse Agreement, all warehousing, handling and
other fees and expenses related to the storage and other handling of the Inventory and will reimburse you for all reasonable costs or expenses incurred as a direct result of your compliance with the terms and provisions of this agreement. The Client
has signed below to indicate its confirmation of, and agreement with, the foregoing.
