Section 10.14 hereof or as otherwise modified in accordance with Section 2.01(e)(i) and (ii). If the Commitments have terminated or expired, the Commitment Percentage shall be determined based on the Commitments most recently in effect,

 “Connection Income Taxes” means Other Connection Taxes that are
imposed on or measured by net income (however denominated) or that are franchise Taxes or branch profits Taxes.

of (a) Consolidated Net Income of the Borrower and its consolidated Subsidiaries for such period, (b) Consolidated Interest Expense for such period and (c) charges against income for foreign, federal, state and local income taxes for
such period, all as determined on a consolidated basis in accordance with GAAP. 
 “Consolidated EBITDA” for
any period, with respect to the Borrower and its consolidated Subsidiaries, shall mean the sum of (a) Consolidated EBIT for such period, (b) depreciation expense for such period, (c) amortization expense for such period,

consolidated basis in accordance with GAAP. 
 “Consolidated Interest Coverage Ratio”, as of the last day of
any fiscal quarter, shall mean the ratio of (a) Consolidated EBITDA to (b) Consolidated Interest Expense, in each case of the Borrower and its consolidated Subsidiaries for the four most recently completed fiscal quarters ending on such
day, considered as a single accounting period. If an Acquisition occurs during such period, each element of the Consolidated Interest Coverage Ratio (whether positive or negative) shall be calculated on a pro forma basis as if the Acquisition
had been made, and any Indebtedness or other obligations issued or incurred in connection therewith had been issued or incurred, as of the first day of such period; provided, however, that in making such calculations the Borrower may
ignore, to an extent not unsatisfactory to the Agent or the Required Lenders, those expenses and distributions of the acquired Person, assets or property that would not have been incurred had the Acquisition occurred as of the first day of such
period. In making such pro forma calculation of the Consolidated Interest Expense with respect to Indebtedness or other obligations issued or incurred in connection with the Acquisition, interest expense thereon shall be calculated by using
the actual interest rate incurred by Borrower on Indebtedness issued under this Agreement during the period that such pro forma Indebtedness is, or is deemed to be, outstanding; provided, however, that interest related to Indebtedness
issued in 

  
 5 

 
connection with such Acquisition shall be deemed to accrue only as of the date of such Acquisition rather than the first day of such pro forma period. 

“Consolidated Interest Expense” for any period shall mean the total interest expense of the Borrower and its
consolidated Subsidiaries for such period determined on a consolidated basis in accordance with GAAP, excluding, however, non-cash charges on account of interest rate Swaps to the extent included in determining Consolidated Net Income. 

“Consolidated Leverage Ratio”, as of the last day of each fiscal quarter, shall mean the ratio of (a) the
aggregate Indebtedness of the Borrower and its consolidated Subsidiaries as of such day to (b) Consolidated EBITDA of the Borrower and its consolidated Subsidiaries for the four most recently completed fiscal quarters ending on such day,
considered as a single accounting period. If an Acquisition occurs during such period, the Consolidated Leverage Ratio shall be calculated on a pro forma basis as if the Acquisition had been made as of the first day of such period,
provided that (i) (A) Consolidated EBITDA of the Borrower and its existing consolidated Subsidiaries shall be calculated as set forth in the immediately preceding sentence, and (B) Consolidated EBITDA of the Person or property
that is the subject of the Acquisition shall be calculated either (1) for the four most recently completed fiscal quarters ending on such day, considered as a single accounting period, or (2) for the twelve month period ending on such day,
considered as a single accounting period, whichever is available to the Borrower and is most current, and (ii) the aggregate Indebtedness of the Borrower and its consolidated Subsidiaries as of the date of determination of the Consolidated
Leverage Ratio shall be calculated to include all Indebtedness of the Borrower and its existing consolidated Subsidiaries and all Indebtedness incurred in connection with and after giving effect to the Acquisition (and including, on a pro
forma basis, all Indebtedness to be incurred in connection with the Acquisition but not yet outstanding on such date); provided, however, that in making such calculations the Borrower may ignore, to an extent not unsatisfactory to
the Agent or the Required Lenders, those expenses and distributions of the acquired Person that would not have been incurred had the Acquisition occurred as of the first day of such period. 

“Consolidated Net Income” for any period, with respect to the Borrower and its consolidated Subsidiaries shall mean the

 ARTICLE II 
 REVOLVING CREDIT 
 2.01.    Revolving Credit
Loans. 
 (a)        Revolving Credit Commitments.  Subject to the
terms and conditions and relying upon the representations and warranties herein set forth, each Lender, severally and not jointly, agrees (such agreement being herein called such Lender’s “Revolving Credit Commitment”) to make
loans (the “Revolving Credit Loans”) to the Borrower at any time or from time to time on or after the date hereof and to but not including the Revolving Credit Maturity Date. A Lender shall have no obligation to make any Revolving
Credit Loan to the extent that the aggregate principal amount of such Lender’s Pro Rata share of the total Revolving Credit Extensions of Credit at any time outstanding would exceed such Lender’s Revolving Credit Committed Amount at such
time. Each Lender’s “Revolving Credit Committed Amount” at any time shall be equal to the amount set forth on the Commitment Schedule across from its name. 

  
 24 

 (b)        Nature of
Credit.  Within the limits of time and amount set forth in this Section 2.01, and subject to the provisions of this Agreement, the Borrower may borrow, repay and reborrow Revolving Credit Loans hereunder. 

(c)        Revolving Credit Note.  The obligation of the Borrower to repay the
unpaid principal amount of the Revolving Credit Loans made to it by each Lender and to pay interest thereon shall be evidenced in part by a promissory note of the Borrower, dated the Closing Date, the date any Lender joins this Agreement, or the
date on which a Lender receives a replacement Revolving Credit Note (the “Revolving Credit Notes”) in substantially the form attached hereto as Exhibit A, with the blanks appropriately filled, payable to the order of such
Lender in a face amount equal to such Lender’s Revolving Credit Committed Amount. 

(d)        Maturity.  To the extent not due and payable earlier, the Revolving
Credit Loans shall be due and payable on the Revolving Credit Maturity Date and, to the extent that the aggregate Revolving Credit Extensions of Credit at any time outstanding is in excess of the aggregate of all Revolving Credit Committed Amounts
at such time (whether as a result of the reduction of the Revolving Credit Committed Amounts or otherwise), a portion of the Revolving Credit Loans in an amount equal to such excess shall be immediately due and payable. 

(e)        Changes in Commitments. 

(i)        Borrower may at any time and from time to time permanently reduce in
whole or ratably in part the aggregate amount of the Revolving Credit Commitments to an amount not less than the then existing Revolving Credit Extensions of Credit, by giving Agent not fewer than ten Business Days’ written notice of such
reduction, provided that any such partial reduction shall be in an aggregate amount, for all of the Lenders, of not less than Five Million Dollars ($5,000,000), increased by increments of One Million Dollars ($1,000,000). Agent shall promptly
notify each Lender of the date of each such reduction and such Lender’s proportionate share thereof. After each such reduction, the commitment fees payable hereunder shall be calculated upon the Revolving Credit Committed Amount of all of the
Lenders as so reduced. If Borrower reduces in whole the Revolving Credit Commitments of the Lenders, on the effective date of such reduction (Borrower having prepaid in full the unpaid principal balance, if any, of the Loans, together with all
interest and commitment and other fees accrued and unpaid, and provided that no Letter of Credit Exposure or Swingline Loans shall exist), all of the Revolving Credit Notes and the Swing Line Note shall be delivered to Agent marked
“Canceled” and Agent shall redeliver such Notes to Borrower. Any partial reduction in the Revolving Credit Committed Amount of all of the Lenders shall be effective from the effective date of such reduction as provided above through and
including the Revolving Credit Maturity Date. 
 (ii)       Borrower may
seek at its option, upon at least ten Business Days’ prior written notice to the Agent, to increase the Aggregate Commitment by an amount up to, but not exceeding, an additional One Hundred Million Dollars ($100,000,000) over the Aggregate
Commitment in effect on the Closing Date; provided that any such increase in the Aggregate Commitment shall be, in an aggregate amount, for all of the Lenders, not less than Ten Million Dollars ($10,000,000), increased by increments of

  
 25 

 
One Million Dollars ($1,000,000). Such notice shall specify the amount of any such increase and shall be delivered at a time when no Potential Default or Event of Default has occurred and is
continuing. The Borrower shall, after giving such notice, offer the increase (which may be declined by any Lender in its sole discretion) in the Aggregate Commitment on a ratable basis to the Lenders. If the Lenders do not accept the offered
increase on a ratable basis, the amount of the increase not so accepted may be offered on a non pro-rata basis to one or more Lenders and/or to other banks or financial institutions reasonably acceptable to the Agent. No increase in the Aggregate
Commitment shall become effective until (i) (A) the existing or new Lenders extending such incremental Revolving Credit Commitment amount and the Borrower shall have delivered to the Agent a document in form reasonably satisfactory to the
Agent pursuant to which any such existing Lender confirms the amount of its Revolving Credit Commitment increase, any such new Lender states its Revolving Credit Commitment amount and agrees to assume and accept the obligations and rights of a
Lender hereunder, and the Borrower accepts such incremental Revolving Credit Commitments, and (B) Borrower shall have executed and delivered to Agent and the Lenders such replacement or additional Revolving Credit Notes as shall be required by
Agent, and (ii) the Guarantors shall have delivered to the Agent a signed acknowledgment confirming their continuing obligations under the Guarantees after giving effect to the contemplated increase in the Aggregate Commitment. The Lenders (new
or existing) shall accept an assignment from the existing Lenders, and the existing Lenders shall make an assignment to the new or existing Lender accepting a new or increased Revolving Credit Commitment, of an interest in each then outstanding Loan
(if any) such that, after giving effect thereto, all such Loans are held ratably by the Lenders in proportion to their respective Revolving Credit Commitments. Assignments pursuant to the preceding sentence shall be made in exchange for the
principal amount assigned plus accrued and unpaid interest. Entitlement to ongoing Commitment Fees under Section 2.02(a) or Letter of Credit Fees under Section 3.02(a), as applicable, shall be allocated ratably to the Lenders following
such increase in proportion to the new Revolving Credit Commitments based upon the date such new Revolving Credit Commitment amounts become effective. 
 2.02.    Commitment Fee; Other Fees. 

(a)        The Borrower shall pay to the Agent for the account of each Lender a commitment fee
(the “Commitment Fee”) calculated at the Commitment Fee Rate for each day from and including the date hereof to but not including the Revolving Credit Maturity Date (or such earlier date on which the Revolving Credit Commitment
terminates), on the amount (not less than zero) equal to (i) such Lender’s Revolving Credit Committed Amount minus (ii) such Lender’s Revolving Credit Extensions of Credit on such day. Such Commitment Fee shall be due and payable
for the preceding period for which such fee has not been paid (x) on the first day of each January, April, July and October and (y) on the date of each reduction of the Revolving Credit Committed Amounts on the amount so reduced and
(z) on the Revolving Credit Maturity Date. For purposes hereof, the “Commitment Fee Rate” for each day shall mean the applicable percentage set forth in Annex A based on the Applicable Tier on such day times 1/360.

 (b)        The Borrower shall pay to Agent, for the benefit of the Lenders or for
its benefit, as the case may be, the fees set forth in the Agent Fee Letter. 

  
 26 

 2.03.    Making of Loans.  Whenever the Borrower
desires that the Lenders make Revolving Credit Loans, the Borrower shall provide Standard Notice to the Agent setting forth the following information: 
 (a)        The date, which shall be a Business Day, on which such proposed Loans are to be made; 

(b)        The aggregate principal amount of such proposed Loans, which shall be the sum of the
principal amounts selected pursuant to clause (c) of this Section 2.03, and which shall be an integral multiple of $100,000 for Loans subject to the Base Rate and not less than $1,000,000 or such amount plus an integral multiple of
$250,000 in excess thereof for the Funding Segment of the LIBOR Portion; 

(c)        The interest rate Option or Options selected in accordance with Section 2.04(a)
hereof and the principal amounts selected in accordance with Section 2.04(d) hereof of the Base Rate Portion and each Funding Segment of the LIBOR Portion, as the case may be, of such proposed Loans; and 

(d)        With respect to each such Funding Segment of such proposed Loans, the LIBOR Funding
Period to apply to such Funding Segment, selected in accordance with Section 2.04(c) hereof. 
 Standard Notice having
been so provided, the Agent shall promptly notify each Lender of the information contained therein and of the amount of such Lender’s Loan. Unless any applicable condition specified in Article V hereof has not been satisfied, on the date
specified in such Standard Notice, each Lender shall make the proceeds of its Loan available to the Agent, no later than 2:00 p.m., Pittsburgh time, in funds immediately available at the Agent’s Office. The Agent will make the funds so received
available to the Borrower in funds immediately available at the Agent’s Office. 

2.04.    Interest Rates. 
 (a)        Optional Bases of Borrowing.  The unpaid principal amount of the Loans shall bear interest for each day until due on one or more bases
selected by the Borrower from among the interest rate Options set forth below. Subject to the provisions of this Agreement, the Borrower may select different Options to apply simultaneously to different Portions of the Loans and may select different
Funding Segments to apply simultaneously to different parts of the LIBOR Portion of the Loans. The aggregate number of Funding Segments applicable to the LIBOR Portion of the Loans at any time shall not exceed fifteen. 

(i)           Base Rate Option: A rate per annum (computed on the basis of a year
of 365/366 days and actual days elapsed) for each day equal to the Base Rate for such day plus the Applicable Margin for such day. The “Base Rate” for any day shall mean the greater of (A) the Prime Rate for such day or
(B) 0.50% plus the Federal Funds Effective Rate for such day, such interest rate to change automatically from time to time effective as of the effective date of each change in the Prime Rate or the Federal Funds Effective Rate. 

  
 27 

 (ii)         LIBOR Option: A rate per annum
(based on a year of 360 days and actual days elapsed) for each day equal to the LIBOR for such day plus the Applicable Margin for such day. 
 “LIBOR” shall mean, for any LIBOR Rate Loan for any LIBOR Funding Period therefor, the rate per annum (rounded upwards, if necessary, to the nearest 1/100 of 1%) appearing on Reuters
Screen LIBOR01 Page (or any successor page) as the London interbank offered rate for deposits in Dollars at approximately 11:00 A.M. (London time) two Business Days prior to the first day of such LIBOR Funding Period for a term comparable to
such LIBOR Funding Period. If for any reason such rate is not available, then “LIBOR” shall mean the rate per annum at which, as determined by the Agent in accordance with its customary practices, Dollars in an amount comparable to the
Loans then requested are being offered to leading banks at approximately 11:00 A.M. London time, two Business Days prior to the commencement of the applicable LIBOR Funding Period for settlement in immediately available funds by leading banks
in the London interbank market for a period equal to the LIBOR Funding Period selected. 
 “LIBOR Rate” shall
mean a rate per annum (rounded upwards, if necessary, to the next higher 1/100th of 1%) determined by the Agent pursuant to the following formula: 
  

							
		 	LIBOR Rate = 	 	 LIBOR
	 	
		 		 	1.0 - LIBOR Reserve Percentage	 	

 “LIBOR Reserve Percentage” for any day shall mean the percentage (expressed as a
decimal, rounded upward to the nearest 1/100 of 1%), as determined in good faith by the Agent (which determination shall be conclusive), which is in effect on such day as prescribed by the Board of Governors of the Federal Reserve System (or any
successor) representing the maximum reserve requirement (including, without limitation, supplemental, marginal and emergency reserve requirements) with respect to eurocurrency funding (currently referred to as “Eurocurrency liabilities”)
of a member bank in such System. The LIBOR Rate shall be adjusted automatically as of the effective date of each change in the LIBOR Reserve Percentage. The LIBOR Option shall be calculated in accordance with the foregoing whether or not any Lender
is actually required to hold reserves in connection with its eurocurrency funding or, if required to hold such reserves, is required to hold reserves at the “LIBOR Reserve Percentage” as herein defined. 

The Agent shall give prompt notice to the Borrower and to the Lenders of the LIBOR Rate determined or adjusted in accordance with the
definition of the LIBOR Rate, which determination or adjustment shall be conclusive if made in good faith. 

(b)       Applicable Margin.  The Applicable Margin for each day shall mean the
applicable percentage set forth in Annex A for each interest rate option based on the Applicable Tier on such day, provided that, from the Closing Date through the date on which the Borrower furnishes (or is required by
Section 6.01(d) to furnish) its compliance certificate for the fiscal year ending March 31, 2012, (and until the Applicable Tier is recalculated in accordance with the third sentence set forth on Annex A), the Applicable Tier shall
be Tier III. The Applicable Margin with respect to Loans which bear interest based on the Base Rate is sometimes referred to herein as the “Applicable Base Rate Margin” and the Applicable Margin with respect to the

Loans which bear interest based on the LIBOR Rate (including the Swingline LIBOR Rate) is sometimes referred to herein as the “Applicable LIBOR Rate Margin.” 

(c)        LIBOR Funding Periods.  At any time when the Borrower shall select,
convert to or renew the LIBOR Option to apply to any part of the Loans, the Borrower shall specify one or more periods during which the LIBOR Option shall apply, such periods being one, two, three or six months or one year (as available)
(“LIBOR Funding Period”); provided, that (i) each LIBOR Funding Period shall begin on a London Business Day, and the term “month”, when used in connection with a LIBOR Funding Period, shall be construed
in accordance with prevailing practices in the interbank eurodollar market at the commencement of such LIBOR Funding Period, as determined in good faith by the Agent (which determination shall be conclusive); (ii) the Borrower may not select a
LIBOR Funding Period that would end after the Revolving Credit Maturity Date; and (iii) the Borrower shall, in selecting any LIBOR Funding Period, allow for scheduled mandatory payments of the Loans. Any LIBOR Funding Period which would
otherwise end on a date which is not a London Business Day shall be extended to the next succeeding London Business Day unless such Business Day falls in the next calendar month, in which case such LIBOR Funding Period shall end on the immediately
preceding London Business Day. The Borrower shall not select the LIBOR Option to be applicable to a Portion of the Loans if after giving effect to such selection of the LIBOR Option more than fifteen LIBOR Funding Segments would then be in effect.

 (d)        Transactional Amounts.  Every selection of, conversion
from, conversion to or renewal of an interest rate Option and every payment or prepayment of any Loans shall be in a principal amount such that after giving effect thereto the aggregate principal amount of (i) the Base Rate Portion shall be for
not less than the lesser of $100,000 or the maximum amount available for Loans to which the Basic Rate option applies and (ii) each Funding Segment of the LIBOR Portion of the Loans shall be $1,000,000 or an integral multiple of $250,000 in
excess thereof. 
 (e)        LIBOR Unascertainable;
Impracticability.  If 
 (i)          on any
date on which a LIBOR would otherwise be set the Agent (in the case of clauses (A) or (B) below) or any Lender (in the case of clause (C) below) shall have determined in good faith (which determination shall be conclusive) that:

 (A)       adequate and reasonable means do not exist for ascertaining
such LIBOR, 
 (B)       a contingency has occurred which materially and
adversely affects the interbank eurodollar market, or 
 (C)       the
effective cost to such Lender of funding a proposed Funding Segment of the LIBOR Portion from a Corresponding Source of Funds shall exceed the LIBOR applicable to such Funding Segment, or 

(ii)         at any time any Lender shall have determined in good faith
(which determination shall be conclusive) that the making, maintenance or funding of any part of the LIBOR Portion has been made impracticable or unlawful by compliance by such 

  
 29 

 
Lender or a Notional LIBOR Funding Office in good faith with any Law or guideline or interpretation or administration thereof by any Governmental Authority charged with the interpretation or
administration thereof or with any request or directive of any such Governmental Authority (whether or not having the force of Law); 
 then,
and in any such event, the Agent or such Lender, as the case may be, may notify the Borrower of such determination (and any Lender giving such notice shall notify the Agent). Upon such date as shall be specified in such notice (which shall not be
earlier than the date such notice is given), the obligation of each of the Lenders to allow the Borrower to select, convert to or renew the LIBOR Option shall be suspended until the Agent or such Lender, as the case may be, shall have later notified
the Borrower (and any Lender giving such notice shall notify the Agent) of the Agent’s or such Lender’s determination in good faith (which determination shall be conclusive) that the circumstance giving rise to such previous determination
no longer exist. 
 If any Lender notifies the Borrower of a determination under subsection (ii) of this
Section 2.04(e), the LIBOR Portion of the Loans of such Lender (the “Affected Lender”) shall automatically be converted to the Base Rate Option as of the date specified in such notice (and accrued interest thereon shall be due
and payable on such date). 
 If at the time the Agent or a Lender makes a determination under subsection (i) or
(ii) of this Section 2.04(e) the Borrower previously has notified the Agent that it wishes to select, convert to or renew the LIBOR Option with respect to any proposed Loans but such Loans have not yet been made, such notification shall be
deemed to provide for selection of, conversion to or renewal of the Base Rate Option instead of the LIBOR Option with respect to such Loans or, in the case of a determination by a Lender, such Loans of such Lender. 

2.05.    Conversion or Renewal of Interest Rate Options. 

(a)        Conversion or Renewal.  Subject to the provisions of Sections
2.09(c) and 2.10(b) hereof, and if no Event of Default or Potential Default shall have occurred and be continuing or shall exist, the Borrower may convert any part of the Loans from any interest rate Option or Options to one or more different
interest rate Options and may renew the LIBOR Option as to any Funding Segment of the LIBOR Portion: 

(i)        At any time with respect to conversion from the Base Rate Option; or

 (ii)       At the expiration of any LIBOR Funding Period with respect to
conversions from or renewals of the LIBOR Option, as to the Funding Segment corresponding to such expiring LIBOR Funding Period. 
 Whenever the
Borrower desires to convert or renew any interest rate Option or Options, the Borrower shall provide to the Agent Standard Notice setting forth the following information: 
 (A)       The date, which shall be a Business Day, on which the proposed conversion or renewal is to be made; 

  
 30 

 (B)       The principal amounts selected in accordance
with Section 2.04(d) hereof of the Base Rate Portion and each Funding Segment of the LIBOR Portion to be converted from or renewed; 
 (C)       The interest rate Option or Options selected in accordance with Section 2.04(a) hereof and the principal amounts selected in accordance with
Section 2.04(d) hereof of the Base Rate Portion and each Funding Segment of the LIBOR Portion to be converted to; and 

(D)       With respect to each Funding Segment to be converted to or renewed, the LIBOR Funding
Period selected in accordance with Section 2.04(c) hereof to apply to such Funding Segment. 
 Standard Notice having been so provided,
after the date specified in such Standard Notice, interest shall be calculated upon the principal amount of the Loans as so converted or renewed. Interest on the principal amount of any part of the Loans converted or renewed (automatically or
otherwise) shall be due and payable on the conversion or renewal date. 

(b)       Failure to Convert or Renew.  Absent due notice from the Borrower of
conversion or renewal in the circumstances described in Section 2.05(a)(ii) hereof, any part of the LIBOR Portion for which such notice is not received shall be converted automatically to the Base Rate Option on the last day of the expiring
LIBOR Funding Period. 
 2.06.    Prepayments Generally. 

(a)       Whenever the Borrower desires or is required to prepay any part of the Loans, the Borrower
shall provide Standard Notice to the Agent setting forth the following information: (i) the date, which shall be a Business Day, on which the proposed prepayment is to be made; (ii) the total principal amount of such prepayment, which
shall be the sum of the principal amounts selected pursuant to clause (iii) of this sentence; and (iii) the principal amounts selected in accordance with Section 2.04(d) hereof of the Base Rate Portion and each part of each Funding
Segment of the LIBOR Portion to be prepaid. Standard Notice having been so provided, on the date specified in such Standard Notice, the principal amounts of the Base Rate Portion and each part of the LIBOR Portion specified in such notice, together
with interest on each such principal amount to such date, shall be due and payable. 

(b)       Upon: (i) any default by Borrower in making any borrowing of, conversion into or
continuation of any LIBOR Portion following Borrower’s delivery of a borrowing request or continuation/conversion notice hereunder or (ii) any prepayment of a LIBOR Portion on any day that is not the last day of the relevant LIBOR Funding
Period (regardless of the source of such prepayment and whether voluntary, by acceleration or otherwise, and including without limitation such prepayment to a Lender being replaced under Section 2.12(d)), the Borrower shall pay an amount
(“LIBOR Rate Breakage Fee”), as calculated in good faith by the Agent (or, in the case of a Lender being replaced under Section 2.12(d), by such Lender), equal to the amount of any losses, expenses and liabilities (including
without limitation any loss of margin and anticipated profits) that Agent, the Lenders or such Lender may sustain as a result of such default or payment. 

  
 31 

 2.07.    Optional Prepayments.  The Borrower shall
have the right at its option from time to time to prepay the Loans in whole or part without premium or penalty (subject, however, to Section 2.10 hereof): 
 (a)       At any time with respect to any part of the Base Rate Portion; or 
 (b)       In accordance with the terms and conditions hereof with respect to LIBOR Portions, including the following. The Borrower shall give the Agent, no later than
12:00 noon, Pittsburgh time, at least three Business Days notice of any proposed prepayment of any Funding Segment of the LIBOR Portions, specifying the proposed date of payment of such Funding Segment and the principal amount to be paid. Each
partial prepayment of the principal amount of the LIBOR Portions or a Funding Segment of the LIBOR Portion shall be in the minimum principal amount of $250,000 and integral multiples of $250,000 and accompanied by the payment of all charges
outstanding on such LIBOR Portions and of all accrued interest on the principal repaid to the date of payment, together with the LIBOR Rate Breakage Fee. Any such prepayment shall be made in accordance with Section 2.06 hereof. 

2.08.    Interest Payment Dates.  Interest on the Base Rate Portion shall be due and payable on the
first Business Day of each calendar month. Interest on each Funding Segment of the LIBOR Portion shall be due and payable on the last day of the corresponding LIBOR Funding Period and, if such LIBOR Funding Period is longer than three months, also
on the last day of the third month of such LIBOR Funding Period (subject to the rules of Section 2.04(c) and Section 10.01). After maturity of any part of the Loans (by acceleration or otherwise), interest on such part of the Loans shall
be due and payable on demand. 
 2.09.    Pro Rata Treatment; Payments Generally; Interest on Overdue
Amounts. 
 (a)       Pro Rata Treatment.  Each borrowing and
conversion and renewal of interest rate Options hereunder shall be made, and all payments made in respect of principal, interest and Commitment Fees due from the Borrower hereunder or under the Notes shall be applied, Pro Rata from and to each
Lender, except for payments of interest involving an Affected Lender as provided in Section 2.04(e) hereof, payments to a Lender under Sections 2.10 or 2.11 hereof, payments to any Issuing Bank pursuant to Section 3.02 hereof and as
otherwise set forth in this Agreement, including pursuant to Section 2.16. The failure of any Lender to make a Loan shall not relieve any other Lender of its obligation to lend hereunder, but neither the Agent nor any Lender shall be
responsible for the failure of any other Lender to make a Loan. 
 (b)       Payments
Generally.  All payments and prepayments to be made by the Borrower in respect of principal, interest, fees, indemnity, expenses or other amounts due from the Borrower hereunder or under any Loan Document shall be payable in Dollars by
12:00 o’clock Noon, Pittsburgh time, on the day when due without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived, and an action therefor shall immediately accrue, without setoff, counterclaim,
withholding or other deduction of any kind or nature. Such payments shall be made to the Agent at its Office in Dollars in funds immediately available at such Office. Any payment or prepayment received by the Agent after 12:00 o’clock Noon,
Pittsburgh time, on any day shall be deemed to have been received on the next succeeding Business Day. The Agent shall distribute to the Lenders all such payments received by it from 

  
 32 

 
the Borrower as promptly as practicable after receipt by the Agent but in no event later than the next Business Day. 
 (c)        Default Interest.  To the extent permitted by Law, from and after the date on which an Event of Default shall have occurred hereunder,
and so long as such Event of Default continues to exist, principal, interest, fees, indemnity, expenses or any other amounts due from the Borrower hereunder or under any other Loan Document, such amounts shall bear interest for each day (before and
after judgment), payable on demand, at a rate per annum (in each case based on a year of 365/366 days and actual days elapsed) which for each day shall be equal to the following: 

(i)        In the case of any part of the LIBOR Portion, (A) until the end
of the applicable then-current LIBOR Funding Period at a rate per annum two percent (2%) above the rate otherwise applicable to such part, and (B) thereafter in accordance with the following clause (ii); and 

(ii)       In the case of any other amount due from the Borrower hereunder or under
any Loan Document, two percent (2%) above the then-current Base Rate Option. 
 To the extent permitted by Law, interest accrued on any
amount which has become due hereunder or under any Loan Document shall compound on a day-by-day basis, and hence shall be added daily to the overdue amount to which such interest relates. 

2.10.    Increased Costs. 
 (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 of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement reflected in the Adjusted LIBOR Rate) or any
Issuing Bank; 
 (ii)       subject any Recipient to any Taxes (other than
(A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations,
or its deposits, reserves, other liabilities or capital attributable thereto; or 

(iii)      impose on any Lender or any Issuing Bank or the London interbank market any
other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or any Letter of Credit or participation therein; 
 and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, converting to, continuing or maintaining any Loan or of maintaining its obligation to
make any such Loan, or to increase the cost to such Lender, such Issuing Bank or such other Recipient 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 

  
 33 

 
amount of any sum received or receivable by such Lender, Issuing Bank or other Recipient hereunder (whether of principal, interest or any other amount) then, upon request of such Lender, Issuing
Bank or other Recipient, the Borrower will pay to such Lender, Issuing Bank or other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender, Issuing Bank or other Recipient, as the case may be, for such
additional costs incurred or reduction suffered. 
 (b)       Capital
Requirements.  If any Lender or Issuing Bank determines that any Change in Law affecting such Lender or Issuing Bank or any lending office of such Lender or such Lender’s or Issuing Bank’s holding company, if any, regarding
capital or liquidity requirements, has or would have the effect of reducing the rate of return on such Lender’s or Issuing Bank’s capital or on the capital of such Lender’s or Issuing Bank’s holding company, if any, as a
consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit or Swingline Loans held by, such Lender, or the Letters of Credit issued by any Issuing Bank, to a level below that which such
Lender or Issuing Bank or such Lender’s or Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or Issuing Bank’s policies and the policies of such Lender’s
or Issuing Bank’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or Issuing
Bank or such Lender’s or Issuing Bank’s holding company for any such reduction suffered. 

(c)       Certificates for Reimbursement.  A certificate of a Lender or Issuing Bank
setting forth the amount or amounts necessary to compensate such Lender or Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section and delivered to the Borrower, shall be conclusive
absent manifest error. The Borrower shall pay such Lender or Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof. 

(d)       Delay in Requests.  Failure or delay on the part of any Lender or Issuing
Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or Issuing Bank’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or
Issuing Bank pursuant to this Section for any increased costs incurred or reductions suffered more than six months prior to the date that such Lender or Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such
increased costs or reductions, and of such Lender’s or Issuing Bank’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 six-month period
referred to above shall be extended to include the period of retroactive effect thereof). 

2.11.    Taxes. 
 (a)       Issuing Bank.  For purposes of this Section 2.11, the term “Lender” includes any Issuing Bank. 

(b)       Payments Free of Taxes.  Any and all payments by or on account of any
obligation of any Loan Party under any Loan Document shall be made without deduction or 

  
 34 

 
withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or
withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental
Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Loan Party shall be increased as necessary so that after such deduction or withholding has been made (including such
deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made. 

(c)       Payment of Other Taxes by the Borrower.  The Loan Parties shall timely pay
to the relevant Governmental Authority in accordance with applicable law, or at the option of the Agent timely reimburse it for the payment of, any Other Taxes. 
 (d)       Indemnification by the Borrower.  The Loan Parties shall jointly and severally indemnify each Recipient, within 10 days after demand therefor,
for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such
Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such
payment or liability delivered to the Borrower by a Lender (with a copy to the Agent), or by the Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error. 

(e)       Indemnification by the Lenders.  Each Lender shall severally indemnify the
Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that any Loan Party has not already indemnified the Agent for such Indemnified Taxes and without limiting the
obligation of the Loan Parties to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 10.14(d) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes
attributable to such Lender, in each case, that are payable or paid by the Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were 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 by the Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Agent to set off and
apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Agent to the Lender from any other source against any amount due to the Agent under this paragraph (e). 

(f)       Evidence of Payments.  As soon as practicable after any payment of
Indemnified Taxes or Other Taxes by any Loan Party to a Governmental Authority, pursuant to this Section 2.11, such Loan Party shall deliver to the 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 Agent. 

  
 35 

 (g)       Status of
Lenders.  (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Agent, at the time or times reasonably
requested by the Borrower or the Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In
addition, any Lender, if reasonably requested by the Borrower or the Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Agent as will enable the Borrower or the Agent to
determine whether or not such Lender is subject to backup withholding or information reporting requirements. 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 2.11(g)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material
unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. 

(ii)       Without limiting the generality of the foregoing, in the event that the Borrower is a U.S.
Borrower, 
 (A)       any Lender that is a U.S. Person shall deliver to the Borrower and
the Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent), executed originals of IRS Form W-9 certifying that such Lender
is exempt from U.S. federal backup withholding tax; 
 (B)       any Foreign Lender shall,
to the extent it is legally entitled to do so, deliver to the Borrower and the Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and
from time to time thereafter upon the reasonable request of the Borrower or the Agent), whichever of the following is applicable: 
 (i)        in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of
interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any
other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

 (ii)       executed originals of IRS Form W-8ECI; 

(iii)      in the case of a Foreign 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 H-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the
Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or 

  
 36 

 
a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed originals of IRS Form
W-8BEN; or 
 (iv)      to the extent a Foreign Lender is not the beneficial
owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit H-2 or Exhibit H-3, IRS Form W-9, and/or other certification
documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender
may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit H-4 on behalf of each such direct and indirect partner; 
 (C)       any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Agent (in such number of copies as shall be requested
by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent), executed originals of any other form prescribed
by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower or the Agent to
determine the withholding or deduction required to be made; and 
 (D)       if a payment
made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such 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 Borrower and the Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Agent such 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 Borrower or the Agent as may be necessary for the Borrower and the Agent to comply with their
obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA”
shall include any amendments made to FATCA after the date of this Agreement. 
 Each Lender agrees that if any form or
certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Agent in writing of its legal inability to do so. 

(h)        Treatment of Certain Refunds.  If any party determines, in its sole
discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.11 (including by the payment of additional amounts pursuant to this Section 2.11), it shall pay
to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such
indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such 

  
 37 

 
indemnified party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (h) (plus any penalties, interest or other charges imposed by the relevant
Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (h), in no event will the indemnified party be required to
pay any amount to an indemnifying party pursuant to this paragraph (h) 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 indemnification
payments or additional amounts giving rise to such refund had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems
confidential) to the indemnifying party or any other Person. 

(i)        Survival.  Each party’s obligations under this
Section 2.11 shall survive the resignation or replacement of the Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any
Loan Document. 
 2.12.   Funding; Mitigation Obligations. 

(a)       Notional Funding.  Each Lender shall have the right from time to time,
prospectively or retrospectively, without notice to the Borrower, to deem any branch, subsidiary or affiliate of such Lender to have made, maintained or funded any part of the LIBOR Portion at any time. Any branch, subsidiary or affiliate so deemed
shall be known as a “Notional LIBOR Funding Office.” Such Lender shall deem any part of the LIBOR Portion of the Loans or the funding therefor to have been transferred to a different Notional LIBOR Funding Office if such transfer
would avoid or cure an event or condition described in Section 2.04(e)(ii) hereof or would lessen compensation payable by the Borrower under Section 2.10 hereof, and if such Lender determines in its sole discretion that such transfer would
be practicable and would not have a Material Adverse Effect on such part of the Loans, such Lender or any Notional LIBOR Funding Office (it being assumed for purposes of such determination that each part of the LIBOR Portion is actually made or
maintained by or funded through the corresponding Notional LIBOR Funding Office). Notional LIBOR Funding Offices may be selected by such Lender without regard to such Lender’s actual methods of making, maintaining or funding Loans or any
sources of funding actually used by or available to such Lender. 
 (b)       Actual
Funding.  Each Lender shall have the right from time to time to make or maintain any part of the LIBOR Portion by arranging for a branch, subsidiary or affiliate of such Lender to make or maintain such part of the LIBOR Portion. Such
Lender shall have the right to (i) hold any applicable Note payable to its order for the benefit and account of such branch, subsidiary or affiliate or (ii) request the Borrower to issue one or more substitute promissory notes in the
principal amount of such LIBOR Portion, in substantially the form attached hereto as Exhibit A, with the blanks appropriately filled, payable to such branch, subsidiary or affiliate and with appropriate changes reflecting that the holder
thereof is not obligated to make any additional Revolving Credit Loans to the Borrower. The Borrower agrees to comply promptly with any request under subsection (ii) of this Section 2.12(b). If any Lender causes a branch, subsidiary or
affiliate to make or maintain any part of the LIBOR Portion hereunder, all terms and conditions of this Agreement shall, except where the context clearly 

  
 38 

 
requires otherwise, be applicable to such part of the LIBOR Portion and to any note payable to the order of such branch, subsidiary or affiliate to the same extent as if such part of the LIBOR
Portion were made or maintained and such note were the Revolving Credit Note payable to such Lender’s order. 

(c)       Designation of a Different Lending Office.  If any Lender requests
compensation under Section 2.10, or requires the Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.11, then such Lender shall (at the
request of the 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, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.10 or 2.11, as the case may be, in the future, and (ii) would not subject such Lender to any unreimbursed cost
or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. 

(d)       Replacement of Lenders.  If any Lender requests compensation under
Section 2.10, or if the Borrower is required to pay additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.11 and, in each case, such Lender has declined or is unable to designate
a different lending office in accordance with Section 2.12(c), or if any Lender is a Defaulting Lender or a Non-Consenting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Agent, require such
Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 10.14), all of its interests, rights and obligations under this Agreement and the related Loan
Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that: 

(i)        the Borrower shall have paid to the Agent the assignment fee (if any)
specified in Section 10.14; 
 (ii)       such Lender shall have
received payment of an amount equal to the outstanding principal of its Loans and funded Letter of Credit Participation Interest, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents
(including any amounts under Section 2.06(b) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts)); 

(iii)      in the case of any such assignment resulting from a claim for compensation
under Section 2.10 or payments required to be made pursuant to Section 2.11, such assignment will result in a reduction in such compensation or payments thereafter; 

(iv)      such assignment does not conflict with applicable law; and 

  
 39 

 (v)       in the case of any assignment
resulting from a Lender becoming a Non-Consenting Lender, the applicable assignee shall have consented to the applicable amendment, waiver or consent. 
 A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such
assignment and delegation cease to apply. 
 2.13.     Swingline Loans. 

(a)        The Swing Line.  Subject to the terms and conditions set forth
herein (including without limitation the conditions set forth in Section 5.02 hereof), the Swingline Lender agrees to make loans (each such loan, a “Swingline Loan”) in Dollars, to the Borrower from time to time on any Business
Day during the period from the Closing Date to the Revolving Credit Maturity Date in an aggregate amount not to exceed Twenty-five Million Dollars ($25,000,000) outstanding at any time; provided, however, that after giving effect to
any Swingline Loan, (i) the aggregate outstanding amount of all Revolving Credit Loans, Swingline Loans and Letter of Credit Obligations shall not exceed the Aggregate Revolving Credit Committed Amounts of all Lenders and (ii) the
aggregate outstanding amount of the Revolving Credit Loans of any Lender other than the Swingline Lender, plus such Revolving Lender’s Pro Rata share of the outstanding amount of all Letter of Credit Obligations, plus such Lender’s
Pro Rata share of the outstanding amount of all Swingline Loans shall not exceed such Lender’s Revolving Credit Committed Amount. Within the foregoing limits, and subject to the other terms and conditions hereof, the Borrower may borrow, prepay
and reborrow under this Section 2.13. To the extent not due and payable earlier, the Swingline Loans shall be due and payable on the Revolving Credit Maturity Date. Each Swingline Loan shall bear interest as set forth in Section 2.14.
Immediately upon the making of a Swingline Loan, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Swingline Lender a risk participation in such Swingline Loan in an amount equal to the product
of such Revolving Lender’s Pro Rata share times the amount of such Swingline Loan. The Swingline Loans shall be evidenced by the Swingline Note. 
 (b)        Borrowing Procedures. If the Borrower desires that the Swingline Lender make a Swingline Loan, the Borrower shall give irrevocable notice to the
Swingline Lender, which may be given by telephone. Each such notice must be received by the Swingline Lender not later than 12:00 noon, Pittsburgh time on the requested borrowing date, and shall specify (i) the amount to be borrowed, which may
be any amount, and (ii) the requested borrowing date, which shall be a Business Day. Each such telephonic notice shall be confirmed promptly by delivery to the Swingline Lender and the Agent of a written confirmation thereof. After receipt by
the Swingline Lender of request of a Swingline Loan, the Swingline Lender shall make the proceeds of such Swingline Loan available to the Borrower on the borrowing date specified in such notice at the Swingline Lender’s office by crediting the
account of the Borrower on the books of the Swingline Lender in funds immediately available at such office. 

  
 40 

 (c)        Refinancing of Swingline Loans.

 (i)        The Swingline Lender at any time in its sole and absolute
discretion may request, on behalf of the Borrower (each of which hereby irrevocably authorizes the Swingline Lender to so request on its behalf), and the Borrower at any time may request, that a Revolving Loan be made in an amount equal to the
amount of some or all of the Swingline Loans then outstanding. Such request shall be made in accordance with the requirements of Section 2.03, without regard to the minimum and multiples specified therein for the principal amount of Revolving
Credit Loans, but subject to the unutilized portion of the Aggregate Revolving Credit Committed Amounts and to satisfaction of the conditions set forth in Section 5.02. Each Lender shall make an amount equal to its Pro Rata share of the amount
specified in the applicable Standard Notice available to the Agent in funds immediately available at the Agent’s Office for the account of the Swingline Lender not later than 2:00 p.m., Pittsburgh time, on the Business Day specified in such
notice, whereupon, subject to Section 2.13(c)(ii), each Lender that so makes funds available shall be deemed to have made a Revolving Loan bearing interest at the Base Rate Option to the Borrower in such amount. The Agent shall remit the funds
so received from the Lenders to the Swingline Lender. 
 (ii)       If for
any reason the making of Revolving Loans cannot be requested in accordance with Section 2.13(c)(i) or any Swingline Loan cannot be refinanced by the making of Revolving Loans, the Standard Notice submitted by the Swingline Lender as
contemplated by Section 2.13(c)(i) shall be deemed to be a request by the Swingline Lender that each of the Lenders fund its risk participation in the amount of the relevant Swingline Loan and each Revolving Lender’s payment to the Agent
for the account of the Swingline Lender pursuant to Section 2.13(c)(i) shall be deemed payment in respect of such risk participation in the amount of such Swingline Loan. 

(iii)      If any Lender fails to make available to the Agent for the account of the
Swingline Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.13(c) by the time specified in Section 2.13(c)(i), the Swingline Lender shall be entitled to recover from such Lender, 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 Swingline Lender at a rate per annum equal to the applicable Federal Funds Rate for
three Business Days and thereafter at a rate per annum equal to the rate applicable to the relevant Swingline Loan. A certificate of the Swingline Lender submitted to any Lender with respect to any amounts owing under this clause (iii) shall be
conclusive absent manifest error. 
 (iv)      Each Lender’s obligation to
make Revolving Credit Loans or to purchase and fund risk participations in Swingline Loans pursuant to this Section 2.13(c) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any set-off,
counterclaim, recoupment, defense or other right which such Lender may have against the Swingline Lender, the Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Potential Default or Event of Default,
or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Lender’s obligation to make Revolving 

  
 41 

 
Loans pursuant to this Section 2.13(c) is subject to the conditions set forth in Section 5.02. Any such purchase of risk participations by each Lender from the Swingline Lender shall
not relieve or otherwise impair the obligation of the Borrower to repay Swingline Loans, together with interest as provided herein. 
 (d)        Repayment of Participations. 
 (i)        At any time after any Lender has purchased and funded a risk participation in a Swingline Loan, if the Swingline Lender receives any payment on account
of such Swingline Loan, the Swingline Lender will distribute to such Lender its ratable share of such payment (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Revolving Lender’s risk
participation was outstanding and funded). 
 (ii)       If any payment
received by the Swingline Lender in respect of principal or interest on any Swingline Loan is required to be returned by the Swingline Lender, each Lender shall pay to the Swingline Lender its Pro Rata share of such amount on demand of the Swingline
Lender, plus interest thereon from the date of such demand to the date such amount is returned at a rate per annum equal to the applicable Federal Funds Rate. 
 (e)         Interest for Account of Swingline Lender. The Swingline Lender shall be responsible for invoicing the Borrower for interest on the Swingline
Loans. Until each Lender funds its Revolving Credit Loan or risk participation pursuant to this Section 2.13, interest in respect of such Lender’s Pro Rata share of the applicable Swingline Loans shall be solely for the account of the
Swingline Lender. 
 2.14.     Interest on and Payment of Swingline Loans; Other Matters.

 (a)        Certain Definitions.  As used herein, the following
terms have the following meanings: 
 (i)        “Applicable
Swingline Margin” for any day means one-quarter of one percent (0.25%) in excess of the Applicable Base Rate Margin or the Applicable LIBOR Rate Margin, as the case may be, for such day. 

(ii)       “Swingline Interest Period” means, initially, the period
commencing on the Closing Date (the “Start Date”) and ending on the numerically corresponding date one month later, and thereafter each one month period ending on the day of such month that numerically corresponds to the Start Date.
If a Swingline Interest Period is to end in a month for which there is no day which numerically corresponds to the Start Date, the Interest Period will end on the last day of such month. 

(iii)      “Swingline Interest Payment Date” means the first Business Day
of each month. 
 (iv)      “Swingline LIBOR Rate” means,
relative to any Swingline Interest Period, the offered rate for delivery in two London Business Days of deposits of U.S. 

  
 42 

 
Dollars which the British Bankers’ Association fixes as its LIBOR rate for a period approximately equal to such Swingline Interest Period. If the first day of any Swingline Interest Period
is not a day which is both a (x) Business Day and (y) a London Business Day, the Swingline LIBOR Rate shall be determined in reference to the next preceding day which is both a Business Day and a London Business Day. If for any reason the
Swingline LIBOR Rate is unavailable and/or the Swingline Lender is unable to determine the Swingline LIBOR Rate for any Swingline Interest Period, the Swingline Loans shall bear interest based on the Base Rate as contemplated by clause (ii) of
Section 2.14(b). 
 (b)       Interest Rates for Swingline
Loans.  Except as otherwise provided in this Section 2.14, the Swingline Loans shall bear interest for each day at a rate per annum equal to, at the option of the Borrower, (i) the sum of Swingline LIBOR Rate for the
Swingline Interest Period during which such day occurs plus the Applicable Swingline Margin for such day or (ii) the Base Rate for such day plus the Applicable Swingline Margin for such day. Interest on Swingline Loans shall be payable on each
Swingline Interest Payment Date. For avoidance of doubt, Section 2.09(c)(ii) shall apply to Swingline Loans. Notwithstanding anything to the contrary in this Agreement, if participations of the Lenders in any Swingline Loan are funded as
contemplated by Section 2.13(c), such Swingline Loan shall, as of the date the request for such funding is made by the Swingline Lender, bear interest in accordance with clause (ii) of the first sentence of this Section 2.14(b).

 (c)       Payments and Prepayments of Swingline Loans.  The Borrower
shall have the right at any time to prepay Swingline Loans without premium or penalty by giving notice to the Swingline Lender and the Agent of such intended prepayment not later than 11:00 a.m. Pittsburgh time on the date of such proposed
prepayment. Section 2.09(b) hereof shall apply to payments of Swingline Loans. In addition, the Borrower and the Swingline Lender may from time to time agree to arrangements whereby Swingline Loans are repaid by a “sweep” or similar
mechanism. 
 (d)       Swingline Note.  The obligation of the Borrower to
repay the unpaid principal amount of the Swingline Loans made to it by the Swingline Lender and to pay interest thereon shall be evidenced in part by a promissory note of the Borrower, dated the Closing Date (the “Swingline Note”)
in substantially the form attached hereto as Exhibit A-1, with the blanks appropriately filled, payable to the order of the Swingline Lender. 
 (e)       Other Matters with respect to Swingline Loans. References in Article IX of this Agreement to the Issuing Bank shall be deemed to be references to each
of the Issuing Banks and the Swingline Lender. 
 2.15.    Cash Collateral.  At any time
that there shall exist a Defaulting Lender, within one Business Day following the written request of the Agent or any Issuing Bank (with a copy to the Agent) the Borrower shall Cash Collateralize the Issuing Banks’ Fronting Exposure with
respect to such Defaulting Lender (determined after giving effect to Section 2.16(a)(iv) and any Cash Collateral provided by such Defaulting Lender) in an amount not less than the Minimum Collateral Amount. 

  
 43 

 (a)       Grant of Security
Interest.  The Borrower, and to the extent provided by any Defaulting Lender, such Defaulting Lender, hereby grants to the Agent, for the benefit of the Issuing Banks, and agrees to maintain, a first priority security interest in all
such Cash Collateral as security for the Defaulting Lenders’ obligation to fund participations in respect of L/C Obligations, to be applied pursuant to clause (b) below. If at any time the Agent determines that Cash Collateral is subject
to any right or claim of any Person other than the Agent and the Issuing Banks as herein provided or that the total amount of such Cash Collateral is less than the Minimum Collateral Amount, the Borrower will, promptly upon demand by the Agent pay
or provide to the Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency (after giving effect to any Cash Collateral provided by the Defaulting Lender). 

(b)       Application.  Notwithstanding anything to the contrary contained in this
Agreement, Cash Collateral provided under this Section 2.15 or Section 2.16 in respect of Letters of Credit shall be applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in respect of L/C
Obligations (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for
herein. 
 (c)        Termination of Requirement.  Cash Collateral (or
the appropriate portion thereof) provided to reduce any Issuing Bank’s Fronting Exposure shall no longer be required to be held as Cash Collateral pursuant to this Section 2.15 following (i) the elimination of the applicable Fronting
Exposure (including by the termination of Defaulting Lender status of the applicable Lender), or (ii) the determination by the Agent and each Issuing Bank that there exists excess Cash Collateral; provided that, subject to
Section 2.16, the Person providing Cash Collateral and each Issuing Bank may agree that Cash Collateral shall be held to support future anticipated Fronting Exposure or other obligations. 

2.16.    Defaulting Lenders. 
 (a)        Defaulting Lender Adjustments.  Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting
Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by applicable Law: 
 (i)         Waivers and Amendments.  Such 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 the definition of Required Lenders. 

(ii)        Defaulting Lender Waterfall.  Any payment of
principal, interest, fees or other amounts received by the Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VIII or otherwise) or received by the Agent from a Defaulting Lender
pursuant to Section 10.12 shall be applied at such time or times as may be determined by the Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Agent hereunder; second, to the payment on
a pro rata basis of any amounts owing by such Defaulting Lender to any Issuing Bank or Swingline Lender hereunder; third, to Cash Collateralize the Issuing Banks’ Fronting Exposure with respect to such Defaulting Lender in

  
 44 

 
accordance with Section 2.15; fourth, as the Borrower may request (so long as no Potential Default or Event of Default exists), to the funding of any Loan in respect of which such
Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Agent; fifth, if so determined by the Agent and the Borrower, 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 under this Agreement and (y) Cash Collateralize the Issuing Banks’ future Fronting Exposure with respect to such Defaulting Lender
with respect to future Letters of Credit issued under this Agreement in accordance with Section 2.15; sixth, to the payment of any amounts owing to the Lenders, the Issuing Banks or Swingline Lenders as a result of any judgment of a
court of competent jurisdiction obtained by any Lender, the Issuing Banks or Swingline Lenders against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no
Potential Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting
Lender’s breach of its obligations under this Agreement; and eighth, 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 Letter of Credit Participating Interest in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made or the related Letters of Credit were issued at a time when the
conditions set forth in Section 5.02 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and Letter of Credit Participating Interest owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied
to the payment of any Loans of, or Letter of Credit Participating Interest owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in L/C Obligations and Swingline Loans are held by the Lenders pro rata in
accordance with the Commitments under the applicable facility without giving effect to Section 2.16(a)(iv). 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 2.16(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto. 

(iii)        Certain Fees. 

(A)  No Defaulting Lender shall be entitled to receive any Commitment Fee for any period during which that
Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender). 

(B)        Each Defaulting Lender shall be entitled to receive the Letter of
Credit Fee for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Commitment Percentage of the stated amount of Letters of Credit for which it has provided Cash Collateral pursuant to Section 2.15.

  

  
 45 

 (C)       With respect to any
Commitment Fee or Letter of Credit Fee not required to be paid to any Defaulting Lender pursuant to clause (A) or (B) above, the Borrower shall (x) pay to each Non-Defaulting Lender that portion of any such fee otherwise payable to
such Defaulting Lender with respect to such Defaulting Lender’s participation in L/C Obligations or Swingline Loans that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (y) pay to each Issuing Bank
and Swingline Lender, as applicable, the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to such Issuing Bank’s or Swingline Lender’s Fronting Exposure to such Defaulting Lender, and (z) not
be required to pay the remaining amount of any such fee. 

(iv)        Reallocation of Participations to Reduce Fronting
Exposure.  All or any part of such Defaulting Lender’s participation in L/C Obligations and Swingline Loans shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Commitment Percentages
(calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that (x) the conditions set forth in Section 5.02 are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise
notified the Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such reallocation does not cause the aggregate Revolving Credit Exposure of any
Non-Defaulting Lender to exceed such Non-Defaulting 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 that 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. 

(v)         Cash Collateral, Repayment of Swingline
Loans.  If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under Law, (x) first, prepay
Swingline Loans in an amount equal to the Swingline Lenders’ Fronting Exposure and (y) second, Cash Collateralize the Issuing Banks’ Fronting Exposure in accordance with the procedures set forth in Section 2.15. 

(b)        Defaulting Lender Cure.  If the Borrower, the Agent, the Swingline
Lender and each Issuing Bank agree in writing that a Lender is no longer a Defaulting Lender, the 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), that 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 Agent may determine to be
necessary to cause the Loans and funded and unfunded participations in Letters of Credit and Swingline Loans to be held pro rata by the Lenders in accordance with the Commitments under the applicable Facility (without giving effect to
Section 2.16(a)(iv)), 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 the Borrower while that Lender was
a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting 

  
 46 

 
Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. 

(c)        New Swingline Loans/Letters of Credit.  So long as any Lender is a
Defaulting Lender, (i) the Swingline Lender shall not be required to fund any Swingline Loans unless it is satisfied that it will have no Fronting Exposure after giving effect to such Swingline Loan and (ii) no Issuing Bank shall be
required to issue, extend, renew or increase any Letter of Credit unless it is satisfied that it will have no Fronting Exposure after giving effect thereto. 
 2.17.    Agent’s Clawback. 

(a)        Funding by Lenders; Presumption by Agent.  Unless the Agent shall
have received notice from a Lender prior to the proposed date of any borrowing of Loans that such Lender will not make available to the Agent such Lender’s share of such borrowing, the Agent may assume that such Lender has made such share
available on such date in accordance with Section 2.03 and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable borrowing
available to the Agent, then the applicable Lender and the Borrower severally agree to pay to the Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to
the Borrower to but excluding the date of payment to the Agent, at (i) in the case of a payment to be made by such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Agent in accordance with banking industry
rules on interbank compensation, and (ii) in the case of a payment to be made by the Borrower, the interest rate applicable to ABR Loans. If the Borrower and such Lender shall pay such interest to the Agent for the same or an overlapping
period, the Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable borrowing to the Agent, then the amount so paid shall constitute such
Lender’s Loan included in such borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Agent. 

(b)        Payments by Borrower; Presumptions by Agent.  Unless the Agent shall
have received notice from the Borrower prior to the date on which any payment is due to the Agent for the account of the Lenders or the Issuing Banks hereunder that the Borrower will not make such payment, the Agent may assume that the Borrower has
made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Banks, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment,
then each of the Lenders or the Issuing Banks, as the case may be, severally agrees to repay to the Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank, with interest thereon, for each day from and including the date
such amount is distributed to it to but excluding the date of payment to the Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Agent in accordance with banking industry rules on interbank compensation.

 ARTICLE III 
 LETTERS OF CREDIT 
 3.01.    Letters of Credit.

 (a)        Outstanding Letters of Credit.  The Agent or one or more
Issuing Banks previously issued the irrevocable letters of credit set forth on Schedule 3.01 hereto (the “Outstanding Letters of Credit”) pursuant to the Existing Credit Agreement or other agreements between Citizens and the
Borrower. The Borrower, the Lenders, the Agent and the Issuing Banks hereby agree that on the Closing Date, subject to the terms and conditions hereof, the Outstanding Letters of Credit shall be deemed to have been issued hereunder as of the Closing
Date. 
 (b)        General.  Subject to the terms and conditions of
this Agreement, and relying upon the representations and warranties herein set forth and upon the agreements of the Lenders set forth in Sections 3.04 and 3.05 hereof, the Issuing Banks shall issue for the account of the Borrower or any of its
Subsidiaries letters of credit (each, as amended, modified or supplemented from time to time, a “Letter of Credit” and collectively the “Letters of Credit”) at any time or from time to time on or after the date
hereof. 
 (c)        Terms of Letters of Credit. The Borrower shall not
request any Letter of Credit to be issued, except within the following limitations: (i) no Letter of Credit shall be issued on or after the day which is thirty days before the Revolving Credit Maturity Date, (ii) at the time any Letter of
Credit is issued, the aggregate Revolving Credit Extensions of Credit (after giving effect to issuance of the requested Letter of Credit) shall not exceed the sum of the Revolving Credit Committed Amounts of the Lenders at such time, (iii) each
Letter of Credit (unless the reimbursement obligation with respect thereto shall be Cash Collateralized under circumstances and in a manner satisfactory to the applicable Issuing Bank in its sole discretion and reasonably satisfactory to the Agent,
it being understood that no Issuing Bank has any commitment to issue such a Letter of Credit) shall have an expiration date not later than the earlier to occur of (x) two years from the date of issuance thereof and (y) thirty
days before the Revolving Credit Maturity Date, (iv) each Letter of Credit shall be denominated in Dollars or any Other Currency, (v) each Letter of Credit shall be payable only against sight drafts (and not time drafts) and such other
certificates and documents as may be required by such Letter of Credit, and (vi) at any time any Letter of Credit is issued, the aggregate Letter of Credit Obligations (after giving effect to issuance of the requested Letter of Credit) shall
not exceed the Dollar Equivalent of Twenty-Five Million Dollars ($25,000,000). 

(d)        Purposes of Letters of Credit.  Each Letter of Credit shall be
satisfactory in form and substance to the Issuing Bank in its reasonable discretion. Letters of Credit may be used by the Borrower or its Subsidiaries for any proper corporate purpose, including providing credit support for any Indebtedness or other
direct or indirect financing arrangements of the Borrower or its Subsidiaries as permitted by this Agreement. The provisions of this Section 3.01(d) represent only an obligation of the Borrower to the Issuing Banks and the Lenders; the Issuing
Bank shall have no obligation to the Lenders to ascertain the purpose of any Letter of Credit, and the rights and obligations of the Lenders and the Issuing Bank among themselves shall not be impaired or affected by a breach of this
Section 3.01(d). 
  

  
 48 

 (e)        Letters of Credit Issued for
Subsidiaries.  Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Subsidiary, the Borrower shall be obligated to reimburse the Issuing Bank hereunder
for any and all drawings under such Letter of Credit. The Borrower hereby acknowledges that the issuance of Letters of Credit for the account of Subsidiaries inures to the benefit of the Borrower, and that the Borrower’s business derives
substantial benefits from the businesses of such Subsidiaries. 
 3.02.    Letter of Credit Fees.

 (a)        Letter of Credit Fees.  The Borrower shall pay to the
Agent for the account of each Lender with respect to each outstanding Letter of Credit a fee (the “Letter of Credit Fee”) in an amount equal to the Applicable LIBOR Rate Margin set forth in Annex A on the undrawn portion of
the stated amount of such Letter of Credit from time to time. The fee shall be payable quarterly in arrears on the last day of each calendar quarter, commencing with the quarter in which the Letter of Credit is issued and on the last day of each
calendar quarter ending thereafter while such Letter of Credit is outstanding. 

(b)        Facing Fee.  For each Letter of Credit which the Issuing Bank issues
pursuant to this Agreement, the Borrower shall pay to the Agent, for the sole account of the Issuing Bank, payable quarterly in arrears, commencing with the quarter in which the Letter of Credit is issued and at the end of each quarter ending
thereafter while such Letter of Credit is outstanding, a fee (the “Letter of Credit Facing Fee”) in an amount equal to 0.125% per annum of the stated amount of such Letter of Credit. 

(c)        Administrative and Amendment Fees.  The Borrower shall pay to the
Agent, for the sole account of the Issuing Bank, such other administrative, maintenance, amendment, drawing, negotiation and other nominal fees as may be customarily charged by the Issuing Bank in accordance with its standard fee schedules from time
to time in connection with letters of credit. 
 3.03.    Procedure for Issuance of Letters of
Credit. 
 (a)        Standby Letters of Credit.  The Borrower
shall, concurrently with the execution and delivery of this Agreement, execute and deliver to the Issuing Bank, a Continuing Letter of Credit Agreement in substantially the form attached hereto as Exhibit B, and the Borrower may from time to
time request the Issuing Bank to issue a Standby Letter of Credit in accordance with the terms thereof by delivering to the Issuing Bank an application, in such form as may from time to time be reasonably required by the Issuing Bank (the
“Standby Letter of Credit Application”), completed to the satisfaction of the Issuing Bank, together with such other certificates, documents and other papers and information as the Issuing Bank may reasonably request. 

(b)        Documentary Letters of Credit.  The Borrower may from time to time
request, upon at least three Business Days’ notice, the Issuing Bank to issue a Documentary Letter of Credit by delivering to the Issuing Bank an Application and Security Agreement (Documentary Letter of Credit) in substantially the form
attached hereto as Exhibit C or the 

  
 49 

 
Issuing Bank’s then current form of application (the “Documentary Letter of Credit Application”), completed to the satisfaction of the Issuing Bank, together with such other
certificates, documents and other papers and information as the Issuing Bank may reasonably request. Upon receipt of any Documentary Letter of Credit Application, the Issuing Bank will process such Documentary Letter of Credit Application, and the
other certificates, documents and other papers delivered in connection therewith, in accordance with its customary procedures and shall promptly issue such Documentary Letter of Credit (but in no event earlier than two Business Days after receipt by
the Issuing Bank of the Documentary Letter of Credit Application relating thereto) by issuing the original of such Documentary Letter of Credit to the beneficiary thereof and by furnishing a copy thereof to the Borrower and the Agent. 

(c)        Notice to Agent.  In connection with Sections 3.03(a) and 3.03(b),
the Issuing Bank shall promptly notify the Agent (by telephone or otherwise), and furnish the Agent with the proposed form of Letter of Credit to be issued. The Agent shall determine, as of the close of business on the day before such proposed
issuance, whether such proposed Letter of Credit complies with the limitations set forth in Sections 3.01(b) and 3.01(c) hereof. Unless such limitations are not satisfied the Agent shall notify the Issuing Bank (in writing or by telephone promptly
confirmed in writing) that the Issuing Bank is authorized to issue such Letter of Credit. If the Issuing Bank issues a Letter of Credit, it shall deliver the original of such Letter of Credit to the beneficiary thereof or as the Borrower shall
otherwise direct, and shall promptly notify the Agent thereof and furnish a copy thereof to the Agent. 

3.04.    Participating Interests. 
 (a)        Generally.  Concurrently with the issuance of each Letter of Credit in accordance with the terms of this Article III, the Issuing Bank
automatically shall be deemed, irrevocably and unconditionally, to have sold, assigned, transferred and conveyed to each other Lender, and each other Lender automatically shall be deemed, irrevocably and unconditionally, severally to have purchased,
acquired, accepted and assumed from the Issuing Bank, without recourse to, or representation or warranty by, the Issuing Bank, an undivided interest, in a proportion equal to such Lender’s Pro Rata share, in all of the Issuing Bank’s
rights and obligations in, to or under such Letter of Credit, the related Letter of Credit Application, the Letter of Credit Reimbursement Obligations, and all collateral, guarantees and other rights from time to time directly or indirectly securing
the foregoing (such interest of each Lender being referred to herein as a “Letter of Credit Participating Interest”). On the date that any purchasing Lender becomes a party to this Agreement in accordance with Section 10.14 or
Section 2.01(e)(ii) hereof, Letter of Credit Participating Interests in any outstanding Letters of Credit held by the Lender from which such purchasing Lender acquired its interest hereunder shall be proportionately reallotted between such
purchasing Lender and such transferor Lender (and, to the extent such transferor Lender is an Issuing Bank, the purchasing Lender shall be deemed to have acquired a Letter of Credit Participating Interest from such transferor Lender to such extent).

 (b)        Obligations Absolute.  Notwithstanding any other
provision hereof, each Lender hereby agrees that its obligation to participate in each Letter of Credit issued in accordance herewith, its obligation to make the payments specified in Section 3.05 hereof, and the right of the Issuing Bank to
receive such payments in the manner specified therein, are each 

  
 50 

 
absolute, irrevocable and unconditional and shall not be affected by any circumstance whatsoever. The failure of any Lender to make any such payment shall not relieve any other Lender of its
funding obligation hereunder on the date due, but no Lender shall be responsible for the failure of any other Lender to meet its funding obligations hereunder. 
 3.05.    Drawings and Reimbursements. 

(a)        Borrower’s Reimbursement Obligation.  The Borrower hereby
agrees to reimburse the Issuing Bank, by making payment to the Agent for the account of the Issuing Bank and the Lenders in accordance with Section 2.09(b) hereof on the date of each payment made by the Issuing Bank under any Letter of Credit
issued on behalf of the Borrower in an amount equal to the Dollar Equivalent Amount of the amount so paid by the Issuing Bank, without notice, protest or demand, all of which are hereby waived, and an action therefor shall immediately accrue. To the
extent such payment is not timely made, the Borrower hereby agrees to pay to the Agent, for the account of the Issuing Bank and the Lenders, on demand, interest on any unreimbursed Letter of Credit Reimbursement Obligations for each day from and
including the date of such payment by the Issuing Bank until paid (before and after judgment) in accordance with Section 2.09(c) hereof, at the rate per annum set forth in Section 2.09(c)(ii) hereof. 

(b)        Payment by Lenders on Account of Unreimbursed Draws.  If the Issuing
Bank makes a payment under any Letter of Credit and is not reimbursed in full therefor on such payment date in accordance with Section 3.05(a) hereof, the Issuing Bank will promptly notify the Agent thereof (which notice may be by telephone
promptly confirmed in writing), and the Agent shall forthwith notify each Lender (which notice may be by telephone promptly confirmed in writing) thereof. No later than the Agent’s close of business on the date such notice is given, each such
Lender will pay to the Agent, for the account of the Issuing Bank, in immediately available funds, an amount equal to the Dollar Equivalent Amount of such Lender’s ratable share of the unreimbursed portion of such payment by the Issuing Bank.
If and to the extent that any Lender fails to make such payment to the Issuing Bank on such date, such Lender shall pay such amount on demand, together with interest, for the Issuing Bank’s own account, for each day from and including the date
of the Issuing Bank’s payment to and including the date of repayment to the Issuing Bank (before and after judgment) at the rate per annum applicable to such Letter of Credit Reimbursement Obligations. 

(c)        Distributions to Participants.  If, at any time, after the Issuing
Bank has made a Letter of Credit unreimbursed draw and has received from any Lender such Lender’s share of such Letter of Credit unreimbursed draw, and the Issuing Bank receives any payment or makes any application of funds on account of the
Letter of Credit Reimbursement Obligation arising from such Letter of Credit unreimbursed draw, the Issuing Bank will pay to the Agent, for the account of such Lender, such Lender’s Pro Rata share of such payment. 

(d)        Rescission.  If any payment received by the Issuing Bank, or any
application made by the Issuing Bank on account of any Letter of Credit Reimbursement Obligation shall be rescinded or otherwise shall be required to be returned or paid over by the Issuing Bank for any reason at any time, whether before or after
the termination of this Agreement (or the Issuing Bank believes in good faith that such rescission, return or payment is required, whether or not such matter has been adjudicated), each such Lender will, promptly

  
 51 

 
upon notice from the Agent or the Issuing Bank, pay over to the Agent for the account of the Issuing Bank its ratable share of the amount so rescinded, returned or paid over, together with its
ratable share of any interest or penalties payable with respect thereto. 

(e)        Equalization.  If any Lender receives any payment or makes any
application on account of its Letter of Credit Participating Interest, such Lender shall forthwith pay over to the Issuing Bank, in Dollars and in like kind of funds received or applied by it the amount in excess of such Lender’s Pro Rata share
of the amount so received or applied. 
 3.06.    Obligations Absolute.  The payment
obligations of the Borrower under Section 3.05 shall be absolute, irrevocable and unconditional and shall be paid strictly in accordance with the terms of this Agreement under any and all circumstances, including, without limitation, the
following circumstances: 
 (a)        any lack of validity or enforceability of any
Letter of Credit or any of the Loan Documents; 
 (b)        any amendment or waiver of
or any consent to departures from all or any of the Loan Documents; 
 (c)        any
exchange, release or non-perfection of any collateral, or any release or amendment or waiver of or consent to departure from any guaranty; 
 (d)        the existence of any claim, set-off, defense or other right which the Borrower may have at any time against any beneficiary, or any transferee, of any
Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the Lender, or any other Person, whether in connection with this Agreement, the transactions contemplated herein, or any unrelated transaction;

 (e)        any statement or any other document presented under any Letter of Credit
opened for its account proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; 
 (f)         payment by the Issuing Bank under any Letter of Credit against presentation of a draft or certificate which does not comply with the terms of such
Letter of Credit, except payment resulting solely from the gross negligence or willful misconduct of the Issuing Bank; or 

(g)        any other circumstances or happening whatsoever, whether or not similar to any of the
foregoing, except (i) payment by the Issuing Bank under any Letter of Credit resulting solely from the gross negligence or willful misconduct of the Issuing Bank and (ii) payment by the Issuing Bank after the Revolving Credit Maturity Date
under any Letter of Credit the stated expiration date of which was, on the date such Letter of Credit was issued, after the Revolving Credit Maturity Date. 
 3.07.    Letter of Credit Application.  The representations, warranties and covenants by the Borrower, and the rights and remedies of the Issuing Bank, under any
Letter of Credit Application relating to any Letter of Credit are in addition to, and not in limitation or 

  
 52 

 
derogation of, representations, warranties and covenants by the Borrower, and rights and remedies of the Issuing Bank and the Lenders, under this Agreement, the Loan Documents, and applicable
Law. The Borrower acknowledges and agrees that all rights of the Issuing Bank under any Letter of Credit Application shall inure to the benefit of each Lender to the extent of its Commitment Percentage as fully as if such Lender was a party to such
Letter of Credit Application. In the event of any inconsistency between the terms of this Agreement and any Letter of Credit Application and to the extent that any Letter of Credit Application and this Agreement address substantially the same
matter, this Agreement shall prevail and the Letter of Credit Application shall, to such extent, be of no effect. 

3.08.    Cash Collateral for Letters of Credit. 

(a)        Cash Collateral for Letter of Credit Exposure Following Repayment of Revolving
Credit Loans or Mandatory Prepayments.  To the extent that this Agreement or any other Loan Document requires a payment or prepayment to be made with respect to the Revolving Credit Loans (whether at maturity, by acceleration or
otherwise), such provision shall be construed as follows: (i) if the amount of such payment or prepayment is less than or equal to the amount of the outstanding Revolving Credit Loans and Letter of Credit Reimbursement Obligations at such time,
then such payment or prepayment shall be applied to the payment of principal of and interest on the outstanding Revolving Credit Loans and Letter of Credit Reimbursement Obligations (whether or not such payment or prepayment would require the
Borrower to pay any amount under Section 2.10(b) hereof); and (ii) if the amount of such payment or prepayment is greater than the amount of outstanding Revolving Credit Loans and Letter of Credit Reimbursement Obligations at such time,
then (A) such payment or prepayment shall be applied to the principal of and interest accrued on the outstanding Revolving Credit Loans and Letter of Credit Reimbursement Obligations (whether or not such payment or prepayment would require the
Borrower to pay any amount under Section 2.10(b) hereof) and (B) the Borrower shall immediately pay to the Agent cash or cash equivalents for deposit in the Letter of Credit Collateral Account in an amount equal to the amount by which such
payment or prepayment exceeds the outstanding Revolving Credit Loans and Letter of Credit Reimbursement Obligations; provided, however, that the amount required to be paid under clause (B) shall not exceed the aggregate Letter of
Credit Exposure at such time minus the balance in the Letter of Credit Collateral Account at such time. To the extent that Section 3.11(a)(iii) of this Agreement requires a mandatory prepayment the Borrower shall immediately pay to the Agent
cash or cash equivalents for deposit in the Letter of Credit Collateral Account in an amount equal to the amount by which such mandatory prepayment exceeds the Base Rate Portion of outstanding Revolving Credit Loans. 

(b)        Letter of Credit Collateral Account.  The Agent shall maintain in
its own name an interest bearing deposit account (the “Letter of Credit Collateral Account”) over which the Agent on behalf of the Lenders shall have sole dominion and control, and the Borrower shall have no right to withdraw or
cause the Agent to withdraw any funds deposited therein. The Agent shall deposit into the Letter of Credit Collateral Account such cash or cash equivalents as this Agreement or any Loan Document requires to be paid therein. As security for the
payment of all Obligations, the Borrower hereby grants, conveys, assigns, pledges and transfers to the Agent, and creates in the Agent’s favor for the benefit of the Lenders a continuing Lien on and security interest in, the Letter of Credit
Collateral Account, all amounts from time to time on 

  
 53 

 
deposit therein, all proceeds of the conversion, voluntary or involuntary, thereof into cash, instruments, securities or other property, and all other proceeds thereof. The Borrower hereby
represents, warrants, covenants and agrees that such Lien shall at all times be valid, perfected and of first priority, subject to no other Lien whatsoever, and the Borrower shall take or cause to be taken such actions and execute and deliver such
instruments and documents as may be necessary or, in the Agent’s judgment, desirable to perfect or protect such Lien. The Borrower shall not create or suffer to exist any Lien on any amounts or investment held in the Letter of Credit Collateral
Account other than the Lien in favor of the Agent granted under this Section 3.08(b). 

(c)        Application of Funds.  Subject to the provisions of
Section 8.02(c) hereof, the Agent shall apply funds in the Letter of Credit Collateral Account: (i) on account of principal of and interest on the Letter of Credit Reimbursement Obligations as and when the same become due and payable if
and to the extent that the Borrower fails directly to pay the same, and (ii) if no Letter of Credit Reimbursement Obligations are due and payable and the balance of the Letter of Credit Collateral Account exceeds the aggregate Letter of Credit
Exposure, the excess shall be applied on account of the other Obligations secured hereby. If all such Obligations have been paid in full, all Revolving Credit Commitments terminated and all Letters of Credit have expired, promptly following demand
by the Borrower, the Agent shall release to the Borrower all remaining funds in the Letter of Credit Collateral Account. If an Event of Default shall have occurred and be continuing, interest earned on funds in the Letter of Credit Collateral
Account shall be held by the Agent as part of Letter of Credit Collateral Account and may be applied by the Agent as set forth herein. 
 3.09.    Additional Provisions Regarding Letters of Credit.  The Borrower hereby indemnifies and holds each of the Issuing Banks harmless from and against any and all
claims, damages, losses, liabilities, costs or expenses whatsoever (including reasonable attorneys’ fees) which any of the Issuing Banks may incur (or which may be claimed against any of the Issuing Banks by any entity or entities whatsoever)
by reason of or in connection with the execution and delivery or use or transfer of, or payment of, or failure to pay under, any Letter of Credit, except for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the
extent, caused by any of the Issuing Banks’ deliberate breach of the terms of a Letter of Credit or the gross negligence or willful misconduct of any of the Issuing Banks in determining whether a statement or draft presented under a Letter of
Credit complied with the terms of the Letter of Credit. 
 Neither the Issuing Banks nor any of their officers or directors
shall be liable or responsible for: (a) the use which may be made of any Letter of Credit or for any acts or omissions of the beneficiary or any transferee in connection therewith; (b) the validity, sufficiency or genuineness of documents,
or of any endorsement thereon, even if such documents should in fact prove to be in any or all respects invalid, insufficient, fraudulent or forged; (c) payment by any of the Issuing Banks against presentation of documents which do not comply
with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to a Letter of Credit; or (d) any other circumstances whatsoever in making or failing to make payment under a Letter of Credit,
except only that the Borrower shall have a claim against an Issuing Bank, and such Issuing Bank shall be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential, damages suffered by the

  
 54 

 
Borrower which were caused by such Issuing Bank’s gross negligence, misfeasance or willful misconduct in connection with the matters referred to in clauses (b) through (d) above.

 3.10.    Certain Provisions Relating To the Issuing Banks. 

(a)        General.  The Issuing Banks shall have no duties or responsibilities
except those expressly set forth in this Agreement and the other Loan Documents, and no implied duties or responsibilities on the part of the Issuing Banks shall be read into this Agreement or any Loan Document or shall otherwise exist. The duties
and responsibilities of the Issuing Banks under this Agreement and the other Loan Documents shall be mechanical and administrative in nature, and the Issuing Banks shall not have a fiduciary relationship in respect of any Lender or any other Person.
The Issuing Banks shall not be liable for any action taken or omitted to be taken by it under or in connection with this Agreement or any other Loan Document, unless caused by its own gross negligence or willful misconduct. The Issuing Banks shall
not be under any obligation to ascertain, inquire or give any notice relating to (i) the performance or observance of any of the terms or conditions of this Agreement or any other Loan Document on the part of the Borrower, (ii) the
business, operations, condition (financial or otherwise) or prospects of the Borrower or any other Person, or (iii) the existence of any Event of Default or Potential Default. The Issuing Banks shall not be under any obligation, either
initially or on a continuing basis, to provide the Agent or any Lender with any notices, reports or information of any nature, whether in its possession presently or hereafter, except for such notices, reports and other information expressly
required by this Agreement to be so furnished. 

(b)        Administration.  The Issuing Banks may rely upon any notice or other
communication of any nature (written or oral, including but not limited to telephone conversations, whether or not such notice or other communication is made in a manner permitted or required by this Agreement or any Loan Document) purportedly made
by or on behalf of the proper party or parties, and the Issuing Banks shall not have any duty to verify the identity or authority of any Person giving such notice or other communication. The Issuing Banks may consult with legal counsel (including,
without limitation, in-house counsel for the Issuing Banks or in-house or other counsel for the Borrower), independent public accountants and any other experts selected by it from time to time, and the Issuing Banks shall not be liable for any
action taken or omitted to be taken in good faith in accordance with the advice of such counsel, accountants or experts. 

(c)        Indemnification of Issuing Bank by Lenders.  Each Lender hereby
agrees to reimburse and indemnify each Issuing Bank, in its capacity as such, and its directors, officers, employees and agents (to the extent not reimbursed by the Borrower and without limitation of the obligations of the Borrower to do so), Pro
Rata, from and against any and all amounts, losses, liabilities, claims, damages, expenses, obligations, penalties, actions, judgments, suits, costs or disbursements of any kind or nature (including, without limitation, the fees and disbursements of
counsel for the Issuing Bank or such other Person in connection with any investigative, administrative or judicial proceeding commenced or threatened, whether or not the Issuing Bank or such other Person shall be designated a party thereto) that may
at any time be imposed on, incurred by or asserted against the Issuing Bank, in its capacity as such, or such other Person, as a result of, or arising out of, or in any way related to or by reason of, this Agreement, any other Loan Document, any
transaction from time to time contemplated hereby or thereby, or any 

  
 55 

 
transaction financed in whole or in part or directly or indirectly with the proceeds of any Letter of Credit, provided that no Lender shall be liable for any portion of such amounts,
losses, liabilities, claims, damages, expenses, obligations, penalties, actions, judgments, suits, costs or disbursements resulting solely from the gross negligence or willful misconduct of the Issuing Bank or such other Person, as finally
determined by a court of competent jurisdiction. 
 (d)        Certain Standby
Letters of Credit.  Each Issuing Bank agrees, with respect to Letters of Credit issued on behalf of the Borrower to a bond trustee or other party as credit and/or liquidity support in connection with any industrial revenue bond or
similar instrument, that it will not exercise any remedies available to it under any indenture, pledge agreement or other agreement executed and delivered in connection with the issuance of such bonds or other instruments, including without
limitation any instruction to accelerate the payment of principal of and interest on such bonds or other instruments, without the prior written consent of the Agent and the Required Lenders. 

3.11.    Multicurrency Payments. 
 (a)        Dollar Equivalent Amounts. 
 (i)        Calculation of Dollar Equivalent Amounts.  For the purpose of determining Revolving Credit Exposure generally and for the purpose of
determining the Dollar Equivalent Amount, upon each making and upon each payment of a Letter of Credit denominated in an Other Currency, the Agent shall calculate the Dollar Equivalent Amount of such Letter of Credit as of such date, as the case may
be, and shall provide written confirmation to the Lenders, the Issuing Banks and the Borrower. 

(ii)       Recalculation of Dollar Equivalent Amounts.  In
determining the Dollar Equivalent Amount of the aggregate Revolving Credit Exposure of the Lenders, the Agent may use the respective Dollar Equivalent Amounts for the Letters of Credit pursuant to paragraph (i) of this subsection (a), unless
such Dollar Equivalent Amount so calculated exceeds 90% of the aggregate of all Revolving Credit Committed Amounts, in which case the Agent shall recalculate the Dollar Equivalent Amount of the Letters of Credit outstanding no less frequently than
once each week. The Agent may recalculate the Dollar Equivalent Amounts of each of the Letters of Credit as frequently as it determines to do so in its discretion, provided, that such recalculation shall be made for all of the Letters of
Credit no less frequently than once each week during any period when the aggregate Dollar Equivalent Amount of the aggregate Revolving Credit Exposure of the Lenders exceeds 90% of the aggregate of all Revolving Credit Committed Amounts. 

(iii)      Mandatory Prepayment.  If the Dollar Equivalent Amount of the
aggregate Revolving Credit Exposure of the Lenders exceeds the Revolving Credit Commitment Amount at any time (such excess amount, calculated at any time and from time to time, being referred to herein as the “Exchange Rate L/C Excess
Amount”), then the Borrower shall (A) immediately prepay the principal amount of the Base Rate Portion of Revolving Credit Loans then outstanding, if any, and (B) deposit into the Letter of Credit Collateral Account, an amount
equal to the Exchange Rate L/C Excess Amount 

  
 56 

 
minus the amount of the Base Rate Portion of Revolving Credit Loans prepaid pursuant to clause (A) hereof, so as to reduce the Dollar Equivalent Amount of the aggregate Revolving Credit
Exposures of the Lenders to an amount not exceeding the Revolving Credit Commitment Amount as such time. The amount of such prepayment deposited into the Letter of Credit Collateral Account pursuant to clause (A) of this
Section 3.11(a)(iii) shall be applied to Revolving Credit Loans at the end of the LIBOR Funding Period then in effect. 

(b)        Indemnity.  Notwithstanding anything herein to the contrary, the
full risk of currency fluctuations shall be borne by the Borrower and the Borrower agrees to indemnify and hold harmless each of the Lenders from and against any loss resulting from any draw under any Letter of Credit denominated in any Other
Currency and for which the Issuing Bank in not reimbursed on the day of such drawing.

 So long as any Loan or Letter of Credit is outstanding, any Obligations are outstanding, the Issuing Banks have any obligation to issue, or the Lenders have any obligation to participate in, Letters of
Credit, or the Lenders have any obligation to make any Loan, the Loan Parties hereby covenant to the Agent and each Lender as follows: 
 6.01.    Basic Reporting Requirements. 

(a)        Annual Audit Reports.  As soon as practicable, and in any event not
later than the earlier to occur of the date after the close of each fiscal year of the Borrower by which the Borrower is required to file its annual report on Form 10-K with the SEC (which on the Closing Date is sixty days after the close of such

satisfactory to the Agent. Such opinion shall be free of exceptions or qualifications not acceptable to the Agent and in any event shall be free of any exception or qualification which is of “going concern” or like nature or which relates
to a limited scope of examination. Such opinion in any event shall contain a written statement of such accountants substantially to the effect that (i) such accountants examined such financial statements in

  
 66 

 
accordance with generally accepted auditing standards and accordingly made such tests of accounting records and such other auditing procedures as such accountants considered necessary in the
circumstances and (ii) in the opinion of such accountants such financial statements present fairly the financial position of the Borrower and its consolidated Subsidiaries as of the end of such fiscal year and the results of their operations
and their cash flows and changes in stockholders’ equity for such fiscal year, in conformity with GAAP. 

(b)        Quarterly Consolidated Reports.  As soon as practicable, and in any
event not later than the earlier to occur of the date after the close of each of the first three fiscal quarters of each fiscal year of the Borrower by which the Borrower is required to file its quarterly report on Form 10-Q with the SEC (which on

income and cash flows of the Borrower and its consolidated Subsidiaries for such fiscal quarter and for the period from the beginning of such fiscal year to the end of such fiscal quarter and an unaudited consolidated balance sheet of the Borrower
and its consolidated Subsidiaries as of the close of such fiscal quarter, all in reasonable detail, setting forth in comparative form the corresponding figures for the same periods or as of the same date during the preceding fiscal year (except for
the consolidated balance sheet, which shall set forth in comparative form the corresponding balance sheet as of the prior fiscal year end). Such financial statements shall be certified by a Responsible Officer of the Borrower as presenting fairly
the financial position of the Borrower and its consolidated Subsidiaries as of the end of such fiscal quarter and the results of their operations and their cash flows and changes in stockholders’ equity for such fiscal year, in conformity with
GAAP, subject to normal and recurring year-end audit adjustments.

event within five Business Days after the end of the respective time period provided for in subsections (a) and (b) of this Section 6.01, the Loan Parties shall furnish to the Agent, with a copy for each Lender unaudited consolidating
statements of income of the Borrower and its Subsidiaries for each reporting segment consistent with the Borrower’s SEC filings for such fiscal quarter or fiscal year, as the case may be, and unaudited consolidating balance sheets of the
Borrower and its Subsidiaries for each reporting segment consistent with the Borrower’s SEC filings as of the close of such fiscal quarter or fiscal year, as the case may be, all in reasonable detail. Such statements shall be certified by a

such fiscal quarter or fiscal year, as the case may be, in conformity with GAAP (exclusive of principles of consolidation), subject (in the case of quarterly reports) to normal and recurring year-end audit adjustments. 

(d)        Quarterly Compliance Certificates.  The Loan Parties shall deliver
to the Agent, with a copy for each Lender a Quarterly Compliance Certificate in substantially the form set forth as Exhibit E, duly completed and signed by a Responsible Officer of the Borrower not later than five Business Days after the
delivery of the financial statements referred to in subsections (a) and (b) of this Section 6.01. The Quarterly Compliance Certificate will state, among other reasonable items: (i) that as of the date thereof no Event of Default
or Potential Default has occurred and is continuing or exists, or if an Event of Default or Potential Default 

  
 67 

 
has occurred and is continuing or exists, specifying in detail the nature and period of existence thereof and any action with respect thereto taken or contemplated to be taken by the Loan Parties
and (ii) in reasonable detail the information and calculations necessary to establish compliance with the provisions of Sections 7.02 and 7.03 hereof and (iii) in reasonable detail the information and calculations necessary to determine

reports pursuant to applicable SEC rules and regulations, the Borrower has filed with the SEC the relevant annual or quarterly report referenced in such Quarterly Compliance Certificate and such report is publicly available on the SEC’s
Electronic Data Gathering, Analysis and Retrieval system, or any similar successor system (“EDGAR”), then the Borrower shall not be required to furnish a hard copy of such annual or quarterly report to the Agent and the Lenders. The
Agent and the Lenders are hereby authorized to access the EDGAR system for purposes of retrieving the financial information so filed. 
 If the Borrower does not intend to file its annual and quarterly reports with the SEC in electronic form using EDGAR, the Borrower shall notify the Agent and the Lenders in the manner prescribed herein of
each such annual and quarterly filing. Neither the Agent nor any Lender shall have any duty to search for or obtain any electronic or other filings that the Borrower makes with the SEC, regardless of whether such filings are periodic, supplemental
or otherwise. 
 The Agent’s and the Lenders’ receipt of such reports, information and documents shall not constitute
notice to it of the content thereof or any matter determinable from the content thereof, including the Borrower’s compliance with any of the covenants hereunder, as to which the Agent and the Lenders are entitled to rely upon Quarterly
Compliance Certificates. 
 (e)        Acquisition Disclosure
Certificate.  The Loan Parties shall, within five Business Days after the consummation of any Acquisition permitted by Section 7.11, deliver to the Agent, with a copy for each Lender, a certificate in the form of Exhibit I hereto

operations and cash position of the Borrower and each Subsidiary of the Borrower as of the end of each month, and the amounts and ratios described in Section 7.02 and 7.03 hereof as of the end of each fiscal quarter, in each case in the
forthcoming fiscal year, together with a statement of the assumptions and estimates upon which such projections are based. Such projections, estimates and assumptions, as of the date of preparation thereof, shall

  
 68 

 
be reasonable, made in good faith, shall be consistent with the Loan Documents, and shall represent the Borrower’s best judgment as to such matters. 

(g)        Certain Other Reports and Information.  Promptly upon their becoming

completed fiscal quarter, calculated on a pro forma basis to include any borrowing to be made in connection with such Stock Payment as if such borrowing had occurred on the last day of such fiscal quarter, exceeds 3.00 to 1.00.
Notwithstanding the above, there shall be no limitation on Stock Payments to the Borrower or any Loan Party from any other Loan Party or Non-Loan party. 
 7.10.    Sale-Leasebacks.  Other than pursuant to transactions involving proceeds to the lessee not in excess of $25,000,000 in the aggregate, and other than in

Subsidiaries compete; (iii) the Consolidated Leverage Ratio as of the end of the fiscal quarter most recently completed prior to the consummation of such Acquisition, calculated on a pro forma basis as if the Acquisition had been
consummated at the beginning of the period of four fiscal quarters ending at the end of such fiscal quarter, consistent with the definition of the term “Consolidated Leverage Ratio”, is not greater than 3.00 to 1.00; 

(b)        Joint Venture Investments permitted by Section 7.08(c); 

(c)        A Loan Party (other than the Borrower) may merge out of existence, liquidate, wind-up
or dissolve if such Loan Party has no substantial assets and has been dormant for at least one year or if such merger, liquidation, winding-up or dissolution (i) would not be disadvantageous, in any material respect, to such Loan Party and its
Subsidiaries taken as a whole (as determined in good faith by the Borrower) and (ii) would not materially adversely affect the Lenders (as reasonably determined by the Agent); and 

(d)        A Loan Party, other than the Borrower, may merge with another Loan Party and a
Non-Loan Party may merge with another Non-Loan Party. 
 7.12.    Dispositions of
Properties.  Except as permitted by Section 7.11(c), Section 7.11(d) or Section 7.10, a Loan Party shall not, and shall not permit any of its Subsidiaries to, sell, convey, assign, lease, transfer, abandon or otherwise
dispose of, voluntarily or involuntarily, any of its properties to a Person other than another Loan Party, except: 

(a)        Each Loan Party and each Non-Loan Party may sell inventory in the ordinary course of
business; 
 (b)        Each Loan Party and each Non-Loan Party may license or
otherwise reasonably convey its intellectual property and other intangible assets to the extent and in the manner that is characteristic of the industry of the Loan Parties provided that such Loan Party or Non-Loan Party shall do nothing to
prevent a collateral assignment of any such license agreement to the Agent, for the benefit of the Lenders; 

  
 78 

 (c)       Each Loan Party and each Non-Loan Party may
dispose of property which is obsolete or no longer useful in the business of the Borrower or such Subsidiary; and 

(d)       Each Loan Party and each Non-Loan Party may dispose of any Joint Venture Investment.

 7.13.    Dealings with Affiliates.  A Loan Party shall not, directly or indirectly,
deal with, in the ordinary course of business or otherwise, any Affiliate (other than another Loan Party), except in transactions which are pursuant to the reasonable requirements of such Loan Party’s ordinary course business operations and
which are on no less favorable terms to such Loan Party than would be the case with a similar transaction with an unaffiliated Person negotiated at arm’s length. 
 7.14.    Capital Expenditures.  A Loan Party shall not, and shall not permit any of its Subsidiaries to, make any Capital Expenditures on or after the date hereof if
an Event of Default or Potential Default shall have occurred and is continuing or if the same shall occur after giving effect thereto. 
 7.15.    Limitation on Other Restrictions on Liens.  The Loan Parties shall not enter into, or become or remain (or allow any of its properties to become or remain)
subject to, any agreement, covenant or instrument (other than the Loan Documents) that would prohibit (i) the payment of any Stock Payment to the Lenders, (ii) the incurrence of additional Indebtedness to the Lenders, whether pursuant to
this Agreement or otherwise, or (iii) the grant of any Lien upon any of its properties (now owned or hereafter acquired) (any such agreement, covenant or instrument, or provision thereof, containing such prohibition on the granting of Liens is
referred to hereinafter in this Section 7.15 as a “Negative Pledge Provision”) unless such Negative Pledge Provision expressly permits such Person to grant Liens in favor of the Lenders; such Negative Pledge Provision may
additionally require that, when any Liens are granted to the Lenders, such Liens shall also be granted on a pari passu basis to the obligee of such Negative Pledge Provision. Notwithstanding the foregoing, the following shall not be
prohibited by this Section 7.15: (a) customary provisions of any agreements governing any purchase money Liens or Capitalized Leases otherwise permitted by this Agreement (in which case, any prohibition or limitation shall only be
effective against the assets financed thereby), (b) customary provisions of any licensing agreement for intellectual property restricting assignment or sublicensing, (c) customary provisions restricting subletting, sublicensing or
assignment of any lease governing any leasehold interests of the Borrower or its Subsidiaries and (d) with respect to any Person becoming a Subsidiary in accordance with the terms of this Agreement after the Closing Date, any agreement in
effect at the time such Person becomes a Subsidiary so long as such agreement was not entered into in contemplation of such Person becoming a Subsidiary and any such prohibition only applies to such Subsidiary. Notwithstanding anything to the
contrary in this Section 7.15, no Loan Party and no Subsidiary thereof shall be permitted to grant any such obligee any Liens which are not permitted by Section 7.05 hereof.

 ARTICLE IX 
 THE AGENT 
 9.01.    Appointment and
Authority.  Each of the Lenders and the Issuing Banks hereby irrevocably appoints Citizens Bank of Pennsylvania to act on its behalf as the Agent hereunder and under the other Loan Documents and authorizes the Agent to take such
actions on its behalf and to exercise such powers as are delegated to the 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 Agent, the Lenders and the Issuing Banks, and neither the Borrower nor any other Loan Party shall have rights as a third-party beneficiary of any of such provisions. It is understood and agreed that the use of the term “Agent” herein
or in any other Loan Documents (or any other similar term) with reference to the 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 is used
as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties. 
 9.02.    Rights as a Lender.  The Person serving as the Agent 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 the Agent, and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Agent 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, the Borrower or
any Subsidiary or other Affiliate thereof as if such Person were not the Agent hereunder and without any duty to account therefor to the Lenders. 
 9.03.    Exculpatory Provisions. 

(a)        The Agent shall not have any duties or obligations except those expressly set forth
herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Agent: 

(i)        shall not be subject to any fiduciary or other implied duties,
regardless of whether an Event of Default has occurred and is continuing; 

(ii)       shall not 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 the Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of
the Lenders as shall be expressly provided for herein or in the other Loan Documents); provided that the Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the 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 Debtor Relief Law or that may effect a forfeiture, modification or termination of
property of a Defaulting Lender in violation of any Debtor Relief Law; and 

  
 83 

 (iii)      shall not, 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 the Borrower or any of their Affiliates that is communicated to or obtained by the Person
serving as the Agent or any of its Affiliates in any capacity. 
 (b)        The Agent
shall not 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 the Agent shall believe in good faith
shall be necessary, under the circumstances as provided in Sections 8.02 and 10.03), or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable
judgment. The Agent shall be deemed not to have knowledge of any Event of Default unless and until notice describing such Event of Default is given to the Agent in writing by the Borrower, a Lender or an Issuing Bank. 

(c)        The Agent shall not 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 Event of 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 V or elsewhere herein, other than to confirm receipt of items
expressly required to be delivered to the Agent. 
 9.04.    Reliance by Agent.  The 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. The 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, extension, renewal or increase of a Letter of Credit, that by its terms must
be fulfilled to the satisfaction of a Lender or an Issuing Bank, the Agent may presume that such condition is satisfactory to such Lender or Issuing Bank unless the Agent shall have received notice to the contrary from such Lender or Issuing Bank
prior to the making of such Loan or the issuance of such Letter of Credit. The Agent may consult with legal counsel (who may be counsel for the 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. 

9.05.    Delegation of Duties.  The 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 Agent. The 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 Agent and any such sub-agent, and shall apply to their respective

  
 84 

 
activities in connection with the syndication of the Facilities as well as activities as Agent. The 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 nonappealable judgment that the Agent acted with gross negligence or willful misconduct in the selection of such sub-agents. 

9.06.    Resignation of Agent. 
 (a)        The Agent may at any time give notice of its resignation to the Lenders, the Issuing Banks and the Borrower. Upon receipt of any such notice of
resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a bank with an office in Pittsburgh, Pennsylvania or New York, New York, or an Affiliate of any such bank with an
office in Pittsburgh, Pennsylvania or New York, New York. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation (or
such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Agent may (but shall not be obligated to), on behalf of the Lenders and the Issuing Banks, appoint a successor Agent
meeting the qualifications set forth above. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date. 

(b)        If the Person serving as Agent is a Defaulting Lender pursuant to clause (d) of
the definition thereof, the Required Lenders may, to the extent permitted by applicable Law, by notice in writing to the Borrower and such Person remove such Person as Agent and, in consultation with the Borrower, appoint a successor. If no such
successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days (or such earlier day as shall be agreed by the Required Lenders) (the “Removal Effective Date”), then such
removal shall nonetheless become effective in accordance with such notice on the Removal Effective Date. 

(c)        With effect from the Resignation Effective Date or the Removal Effective Date (as
applicable) (1) the retiring or removed Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents and (2) except for any indemnity payments owed to the retiring or removed Agent, all payments,
communications and determinations provided to be made by, to or through the Agent shall instead be made by or to each Lender and Issuing Bank directly, until such time, if any, as the Required Lenders appoint a successor Agent as provided for above.
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 removed Agent (other than any rights to indemnity
payments owed to the retiring or removed Agent), and the retiring or removed Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents. The fees payable by the Borrower to a successor Agent shall be
the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring or removed Agent’s resignation or removal hereunder and under the other Loan Documents, the provisions of this
Article and Section 10.06 shall continue in effect for the benefit of such retiring or removed Agent, its sub-agents and their respective Related Parties in 

  
 85 

 
respect of any actions taken or omitted to be taken by any of them while the retiring or removed Agent was acting as Agent. 

9.07.    Non Reliance on Agent and Other Lenders.  Each Lender and Issuing Bank acknowledges that
it has, independently and without reliance upon the Agent 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 and Issuing Bank also acknowledges that it will, independently and without reliance upon the 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. 

9.08.    No Other Duties, etc.  Anything herein to the contrary notwithstanding, none of the Lead
Arranger, Book Manager, Syndication Agent or Co-Documentation Agent listed on the cover page hereof 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 Agent, a Lender or an Issuing Bank hereunder. 
 9.09.    Guaranty Matters.  The
Lenders irrevocably authorize the Agent, at its option and in its discretion, to release any Guarantor from its obligations under a Subsidiary Guaranty if such Person ceases to be a Subsidiary as a result of a transaction permitted under the Loan
Documents. Upon request by the Agent at any time, the Required Lenders will confirm in writing the Agent’s authority to release a Guarantor from its obligations under a Subsidiary Guaranty pursuant to this Section 9.09. 

ARTICLE X 

MISCELLANEOUS 
 10.01.  Holidays.    Whenever any payment or action to be made or taken hereunder or under any other Loan Document shall be stated to be due on a day which is not a
Business Day, such payment or action shall be made or taken on the next following Business Day (except as provided in Section 2.04(c) with respect to LIBOR Funding Periods) and such extension of time shall be included in computing interest or

Borrower, the Agent or any Lender. Any such amendment, modification or supplement made in accordance with the provisions of this Section shall be binding upon the Borrower, each Lender and the Agent. The Agent shall enter into such amendments,
modifications or supplements from time to time as directed by the Required Lenders, and only as so directed, provided, that no such amendment, modification or supplement may be made which will: 

(a)        Increase the Revolving Credit Committed Amount of any Lender over the amount thereof

and provided, further, that Assignment and Assumptions may be entered into in the manner provided in Section 10.14 hereof. Any such
amendment, modification or supplement must be in writing and shall be effective only to the extent set forth in such writing. Any Event of Default or Potential Default waived or consented to in any such amendment, modification or supplement

  
 87 

 
shall be deemed to be cured and not continuing to the extent and for the period set forth in such waiver or consent, but no such waiver or consent shall extend to any other or subsequent Event of
Default or Potential Default or impair any right consequent thereto. 
 10.04.  No Implied Waiver; Cumulative

thereof or of any other right, power or privilege. The rights and remedies of the Agent and the Lenders under this Agreement and any other Loan Document are cumulative and not exclusive of any rights or remedies which either the Agent or any Lender
would otherwise have hereunder or thereunder, at law, in equity or otherwise.

to notices to any Lender or the Issuing Banks pursuant to Article II if such Lender or Issuing Bank, as applicable, has notified the Agent that it is incapable of receiving notices under such Article by electronic communication. The Agent or
the Borrower may, in their discretion, agree to accept notices and

a manner specified herein, were incomplete or were not preceded or followed by any other form of notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from any confirmation thereof. The Loan Parties shall
indemnify the Agent, the Issuing Banks, each Lender and the Affiliates of each of them from all losses, costs, expenses and liabilities resulting from the reliance by such Person on each notice purportedly given by or on behalf of the Borrower. All
telephonic notices to and other telephonic communications with the Agent may be recorded by the Agent, and each of the parties hereto hereby consents to such recording.

 90 

 
contemplated hereby or thereby, (ii) any Loan or Letter of Credit or the use or proposed use of the proceeds therefrom (including any refusal by any Issuing Bank to honor a demand for
payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Environmental Concern Materials on or
from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Claim related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or
proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by the Borrower or any other Loan Party, and regardless of whether any Indemnitee is a party thereto;
provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and
nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or (y) result from a claim brought by the Borrower or any other Loan Party against an Indemnitee for breach in bad faith of such
Indemnitee’s obligations hereunder or under any other Loan Document, if the Borrower or such Loan Party has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction. This
Section 10.06(b) shall not apply with respect to Taxes other than any Taxes that represent losses, claims, damages, etc. arising from any non-Tax claim. 
 (c)        To the extent that the Borrower for any reason fails to indefeasibly pay any amount required under paragraph (a) or (b) of this Section to be
paid by it to the Agent (or any sub-agent thereof), any Issuing Bank, the Swingline Lender or any Related Party of any of the foregoing, each Lender severally agrees to pay to the Agent (or any such sub-agent), such Issuing Bank, the Swingline
Lender or such Related Party, as the case may be, such Lender’s Pro Rata share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount (including any such unpaid amount in
respect of a claim asserted by such Lender); provided, that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Agent (or any such sub-agent),
such Issuing Bank or the Swingline Lender in its capacity as such, or against any Related Party of any of the foregoing acting for the Agent (or any such sub-agent), such Issuing Bank or the Swingline Lender in connection with such capacity. The
obligations of the Lenders under this paragraph (c) are several and not joint. 

(d)        Waiver of Consequential Damages, Etc.  To the fullest extent
permitted by applicable Law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising
out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement of instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or Letter of Credit, or the use of the proceeds
thereof. No Indemnitee referred to in paragraph (b) above shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other
information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby. 

  
 91 

 (e)        Payments.  All amounts
due under this Section shall be payable promptly after demand therefor. 

(f)        Survival.  Each party’s obligations under this Section shall
survive the termination of the Loan Documents and payment of the obligations hereunder. 

10.07.  Severability.  The provisions of this Agreement are intended to be severable. If any provision of
this Agreement shall be held invalid or unenforceable in whole or in part in any jurisdiction such provision shall, as to such jurisdiction, be ineffective to the extent of such invalidity or unenforceability without in any manner affecting the
validity or enforceability thereof in any other jurisdiction or the remaining provisions hereof in any jurisdiction. 

10.08.  Prior Understandings.  This Agreement and the other Loan Documents supersede all prior and
contemporaneous understandings and agreements, whether written or oral, among the parties hereto relating to the transactions provided for herein and therein. 
 10.09.  Duration; Survival.  All representations and warranties of each Loan Party contained herein or in any other Loan Document or made in connection herewith or therewith
shall survive the making of, and shall not be waived by the execution and delivery, of this Agreement or any other Loan Document, any investigation by or knowledge of the Agent or any Lender, the making of any Loan, the issuance of any Letter of
Credit or any other event or condition whatsoever. All covenants and agreements of each Loan Party contained herein or in any other Loan Document shall continue in full force and effect from and after the date hereof so long as the Borrower may
borrow hereunder or request the issuance of Letters of Credit hereunder and until payment in full of all Obligations, except for contingent indemnification obligations. Without limitation, all obligations of the Borrower hereunder or under any other
Loan Document to make payments to or indemnify the Agent or any Lender shall survive the payment in full of all other Obligations, termination of the Borrower’s right to borrow or to request the issuance of Letters of Credit hereunder, and all
other events and conditions whatsoever. In addition, all obligations of each Lender to make payment to or indemnify the Agent shall survive the payment in full by the Borrower of all Obligations, termination of the Borrower’s rights to borrow
hereunder, and all other events or conditions whatsoever. 
 10.10.  Counterparts.  This Agreement
may be executed in any number of counterparts and by the different parties hereto on separate counterparts each of which, when so executed, shall be deemed an original, but all such counterparts shall constitute but one and the same instrument.

 10.11.  Limitation on Payments.  The parties hereto intend to conform to all applicable Laws in
effect from time to time limiting the maximum rate of interest that may be charged or collected. Accordingly, notwithstanding any other provision hereof or of any other Loan Document, the Borrower shall not be required to make any payment to or for
the account of any Lender, and any Lender shall refund any payment made by the Borrower, to the extent that such requirement or such failure to refund would violate or conflict with nonwaivable provisions of applicable Laws limiting the maximum
amount of interest which may be charged or collected by such Lender. 

  
 92 

 10.12.   Set-Off.  If an Event of Default shall have
occurred and be continuing, each Lender, each Issuing Bank, and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest 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, such Issuing Bank or any such Affiliate, to or for the credit or the
account of the Borrower or any other Loan Party against any and all of the obligations of such Borrower or such Loan Party now or hereafter existing under this Agreement or any other Loan Document to such Lender or such Issuing Bank or their
respective Affiliates, irrespective of whether or not such Lender, Issuing Bank or Affiliate shall have made any demand under this Agreement or any other Loan Document and although such obligations of such Borrower or such Loan Party may be
contingent or unmatured or are owed to a branch, office or Affiliate of such Lender or such Issuing Bank different from the branch, office or Affiliate 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 Agent for further application in accordance with the provisions of Section 2.16 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 Agent, the Issuing Banks, and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Agent a statement
describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of each Lender, each Issuing Bank and their respective Affiliates under this Section are in addition to other
rights and remedies (including other rights of setoff) that such Lender, such Issuing Bank or their respective Affiliates may have, each Lender and Issuing Bank agrees to notify the Borrower and the 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. 
 10.13.   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 its Loans or other obligations hereunder resulting in such Lender receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations greater than its pro rata share
thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and such other 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 them; provided that: 
 (i)        if any such
participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and 

(ii)       the provisions of this paragraph shall not be construed to apply to
(x) any payment made by the 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), or (y) any payment obtained by a Lender as
consideration for the assignment of or sale of a participation in any of its Loans or Letter of Credit 

  
 93 

 
Participating Interest to any assignee or participant, other than to the Borrower or any Subsidiary thereof (as to which the provisions of this paragraph shall apply). 

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 each Loan Party rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of each Loan Party in the amount of such
participation. 
 10.14.  Successors and Assigns; Participation; Assignments. 

(a)        Successors and Assigns Generally.  The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that neither the Borrower nor any other Loan Party may assign or otherwise transfer any of its rights or
obligations hereunder or interests herein without the prior written consent of the Agent and each Lender (which consent shall not be unreasonably withheld or delayed), and no Lender may assign or otherwise transfer any of its rights or obligations
hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section or (iii) by way of
pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or transfer by any party hereto 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 paragraph (d) of this Section) 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 assignees all or a portion of its rights and obligations under this Agreement and the other Loan Documents (including all or a portion of its Revolving Credit Commitment and
the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions: 
 (i)           Minimum Amounts. 
 (A)       in the case of an assignment of the entire remaining amount of the assigning Lender’s Revolving Credit Commitment and/or the Loans at the time owing to it
or contemporaneous assignments to related Approved Funds that equal at least the amount specified in paragraph (b)(i)(B) of this Section in the aggregate or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no
minimum amount need be assigned; and 
 (B)       in any case not described
in paragraph (b)(i)(A) of this Section, the aggregate amount of the Revolving Credit Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Revolving Credit Commitment is not then in effect, the principal
outstanding balance of the Loans the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such 

  
 94 

 
assignment is delivered to the 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, in the case of
any assignment in respect of the Loan, unless each of the Agent and, so long as no Event of Default or Potential Default has occurred and is continuing, the Borrower otherwise consents (such consent not to be unreasonably withheld or delayed).

 (ii)         Proportionate Amounts.  Each
partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan or the Revolving Credit Commitment assigned. 

(iii)        Required Consents.  No consent shall be required
for any assignment except to the extent required by paragraph (b)(i)(B) of this Section and, in addition: 

(A)        the consent of the Borrower (such consent not to be unreasonably
withheld or delayed) shall be required unless (x) an Event of Default or Potential Default has occurred and is continuing at the time of such assignment, or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund;
provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Agent within five Business Days after having received notice thereof and provided,
further, that the Borrower’s consent shall not be required during the primary syndication of the Agreement; 
 (B)        the consent of the Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments to a Person who is not a Lender, an
Affiliate of a Lender or an Approved Fund; and 
 (C)        the
consent of each Issuing Bank and the Swingline Lender shall be required for any assignment (such consent not to be unreasonably withheld or delayed). 
 (iv)        Assignment and Assumption.  The parties to each assignment shall execute and deliver to the Agent a duly completed Assignment and
Assumption, in substantially the form of Exhibit G to this Agreement, together with any Note or Notes subject to such assignment and a processing and recordation fee of $3,500; provided that the Agent may, in its sole discretion,
elect to waive such processing and recordation fee in the case of any assignment. The assignee, if it is not a Lender, shall deliver to the Agent an Administrative Questionnaire. 

(v)         No Assignment to Certain Persons.  No such
assignment shall be made to (A) the Borrower or any of the Borrower’s Affiliates or Subsidiaries or (B) 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 (B). 

  
 95 

 (vi)        No Assignment to
Natural Persons.  No such assignment shall be made to a natural Person. 

(vii)       Certain Additional Payments.  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 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 Borrower and the 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 Agent, each Issuing Bank, the Swingline Lender and each other Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its
full pro rata share of all Loans and participations in Letters of Credit and Swingline Loans in accordance with its Commitment 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 Agent pursuant to paragraph (c) of this Section,
from and after the effective date specified in each Assignment and Assumption, the 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 2.10, 2.11 and 10.6 with respect to facts
and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of
any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph 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 paragraph (d) of this Section. 
 On or prior to the effective date specified in any Assignment and Assumption, the Borrower, at its expense, shall execute and deliver to the Agent (for delivery to the assignee) new Notes evidencing such
assignee’s assigned Revolving Credit Commitments or Loans and (for delivery to the transferor Lender) replacement Notes in the principal amount of the Loans or Revolving Credit Commitments retained by the transferor Lender (such Notes to be in
exchange for, but not in payment of, those Notes then held by such transferor Lender). Each such Note shall be dated the date and be substantially in the form of the predecessor Note. The Agent shall mark the predecessor Notes “exchanged”
and deliver them to the Borrower. Accrued interest 

  
 96 

 
and accrued fees shall be paid to the assignee at the same time or times provided in the predecessor Notes and this Agreement. 

(c)        Register.  The Agent, acting solely for this purpose as an agent of
the Borrower, shall maintain at its Office in a copy of each Assignment and Assumption delivered to it and a register (the “Register”) for the recordation of the names and addresses of the Lenders, and the Revolving Credit
Commitment of, and principal amounts (and stated interest) of the Loans owing to, each Lender pursuant to the terms hereof from time to time. The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Agent 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. The Register shall be available for inspection by the Borrower and any 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 the Borrower or Agent, sell participations to any Person (other than a natural Person, any Loan Party, any of the Loan Parties’ Affiliates or Subsidiaries or, in the reasonable judgment of the Agent and the Borrower, a competitor
of a Loan Party or an Affiliate of a competitor of a Loan Party) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement and the other Loan Documents (including all or a
portion of its Revolving Credit Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement and the other Loan Documents shall remain unchanged, (ii) such Lender shall remain
solely responsible to the other parties hereto for the performance of such obligations, and (iii) the Borrower, the Agent, the Issuing Banks and Lenders shall continue to deal solely and directly with such Lender in connection with such
Lender’s rights and obligations under this Agreement and each of the other Loan Documents. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 9.07 with respect to any payments made by such Lender
to its Participant(s). 
 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 this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; 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 subsections (a), (b), (c) or (d) of Section 10.03 hereof that affects such Participant. The Borrower agrees that each Participant
shall be entitled to the benefits of Sections 2.10 and 2.11 (subject to the requirements and limitations therein, including the requirements under Section 2.11(g) (it being understood that the documentation required under Section 2.11(g)
shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant (A) agrees to be
subject to the provisions of Sections 2.12(c) and (d) as if it were an assignee under paragraph (b) of this Section; and (B) shall not be entitled to receive any greater payment under Sections 2.10 or 2.11, with respect to any
participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable
participation. To the extent permitted by Law, each Participant also shall be entitled to the benefits of Section 10.12 as though it were a Lender; provided that such Participant agrees

  
 97 

 
to be subject to Section 10.13 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrower, maintain a register on
which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”);
provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans,
letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit 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. For the avoidance of doubt, the Agent (in its capacity as Agent) shall have no responsibility for maintaining a Participant Register.
Notwithstanding the foregoing, in no event shall any participation by any Lender have the effect of releasing such Lender from its obligations hereunder. 
 (e)        Certain Pledges.  Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this
Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve 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. 

(f)         Financial and Other Information.  Each Loan Party authorizes
the Agent and each Lender to disclose to any Participant and any prospective transferee any and all financial and other information in such Person’s possession concerning any Loan Party and their respective Subsidiaries and affiliates which has
been or may be delivered to such Person by or on behalf of any Loan Party in connection with this Agreement or any other Loan Document or such Person’s credit evaluation of any Loan Party and their respective Subsidiaries and affiliates;
provided, however, that each prospective Participant and each prospective assignee or transferee of any interest in the Loan Documents shall be required to agree to the confidentiality provisions of this Agreement as contained in
Section 10.17 hereto, prior to any such disclosure. 
 10.15.  Governing Law; Submission to Jurisdiction;
Waiver of Jury Trial; Limitation of Liability. 
 (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 TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF PENNSYLVANIA, WITHOUT REGARD TO CHOICE OF LAW

 (b)        Jurisdiction.  THE
BORROWER AND EACH OTHER LOAN PARTY IRREVOCABLY AND UNCONDITIONALLY AGREES THAT IT WILL NOT COMMENCE ANY ACTION, LITIGATION OR PROCEEDING OF ANY KIND OR DESCRIPTION, WHETHER IN LAW OR EQUITY, WHETHER IN CONTRACT OR IN TORT OR OTHERWISE, AGAINST THE
AGENT, ANY LENDER, ANY ISSUING BANK, OR ANY RELATED PARTY OF THE FOREGOING IN ANY WAY RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OF THE TRANSACTIONS RELATING HERETO OR THERETO, IN ANY FORUM OTHER THAN THE COURT OF THE COMMONWEALTH OF
PENNSYLVANIA SITTING IN ALLEGHENY COUNTY, AND OF THE UNITED STATES DISTRICT COURT OF THE WESTERN DISTRICT OF PENNSYLVANIA, AND ANY APPELLATE COURT FROM ANY THEREOF, AND EACH OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY SUBMITS TO THE
JURISDICTIONS OF SUCH COURTS AND AGREED THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION, LITIGATION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH PENNSYLVANIA STATE COURT OR, TO THE FULLEST 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 AGENT, ANY LENDER OR ANY ISSUING BANK MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AGAINST THE BORROWER OR ANY
OTHER LOAN PARTY OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION. 

(c)        Waiver of Venue.  THE BORROWER AND EACH OTHER LOAN PARTY IRREVOCABLY
AND UNCONDITIONALLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT
IN ANY COURT REFERRED TO IN PARAGRAPH (B) OF THIS SECTION. EACH OF THE PARTIES HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY
SUCH COURT. 
 (d)        Service of Process.  EACH PARTY HERETO
IRREVOCABLY CONSENTS TO SERVICE OF PROCESS IN THE MANNER PROVIDED FOR NOTICES IN SECTION 10.05, AND CONSENTS AND AGREES THAT SUCH SERVICE SHALL CONSTITUTE IN EVERY RESPECT VALID AND EFFECTIVE SERVICE. NOTHING IN THIS AGREEMENT WILL AFFECT THE RIGHT
OF ANY PARTY TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW. 

(e)        Waiver of Jury Trial.  EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL 

  
 99 

 
PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR
ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON 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 AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 

10.16    Termination of Existing Revolving Credit Facilities. Upon the execution and delivery of this
Agreement by each of the parties hereto and the satisfaction of each of the other conditions set forth in Section 5.01 hereof, the Existing Revolving Credit Facility and the obligations of the lenders thereunder to extend credit thereunder
shall be, and hereby are, terminated. Notwithstanding the foregoing, to the extent that any Revolving Credit Extensions of Credit or any other Obligations remain outstanding under any of the Existing Revolving Credit Facilities (including without
limitation Letters of Credit), the Loan Parties hereby acknowledge and agree that such Revolving Credit Extensions of Credit and other Obligations (i) shall constitute Obligations of the Loan Parties hereunder and not under any of the Existing
Revolving Credit Facilities, (ii) shall be reallocated among the Lenders on the Closing Date based upon the changes in each Lender’s respective Commitment Percentage, and (iii) to the extent that any Lender under this Agreement
receives a payment on account of such reallocation, neither Section 2.07(b) of the Existing Credit Agreement nor Section 2.06(b) of this Agreement shall apply to such payment. 

10.17    Confidentiality.  Each of the Agent, the Lenders and the Issuing Banks agree to maintain
the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its Related Parties (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 required or requested by any regulatory authority purporting to have jurisdiction over such Person or its Related Parties
(including any self-regulatory authority, such as the National Association of Insurance Commissioners); (c) to the extent required by applicable Laws or regulations 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) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights and obligations under this
Agreement, or (ii) any actual or prospective party (or its Related Parties) to any swap, derivative or other transaction under which payments are to be made by reference to the Borrower and its obligations, this Agreement or payments hereunder;

respective businesses, other than any such information that is available to the Agent, any Lender or any Issuing Bank on a nonconfidential basis prior to disclosure by the Borrower 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.

 FORM OF 

GUARANTY AND SURETYSHIP AGREEMENT 
 THIS GUARANTY AND SURETYSHIP AGREEMENT (this “Agreement”), dated as of the        day of
                                , 20    , is made by
the Guarantors identified as such on the signature page hereof (each, a “Guarantor” and, collectively, the “Guarantors”), to the lenders parties to the Credit Agreement (as defined below) from time to time (the
“Lenders”) and CITIZENS BANK OF PENNSYLVANIA, a banking association organized under the laws of the Commonwealth of Pennsylvania, as agent for the Lenders (in such capacity, together with its successors in such capacity, the
“Agent”). 
 W I T N E S S E T H: 

WHEREAS, the Guarantors, Black Box Corporation, a Delaware corporation (“Borrower”), the Lenders and the Agent entered into
that certain Credit Agreement, dated as of March 23, 2012 (as the same may be amended, restated, modified or supplemented from time to time, the “Credit Agreement”), pursuant to which the Lenders made a revolving credit facility
available to Borrower; and 
 WHEREAS, the Guarantors will derive substantial direct and indirect benefit from the transactions
contemplated by the Credit Agreement; and 
 WHEREAS, it is a condition precedent to the extension of credit under the Credit
Agreement that the Guarantors execute and deliver this Agreement; and 
 WHEREAS, this Agreement, among other things, is made by
the Guarantors to induce the Lenders to enter into the Loan Documents (as defined in the Credit Agreement) and to induce the Lenders to extend credit under the Credit Agreement. 

NOW, THEREFORE, in consideration of the premises and other good and valuable consideration, the receipt of which is hereby acknowledged
by each Guarantor, and intending to be legally bound, each Guarantor hereby agrees as follows: 
 ARTICLE I 

DEFINITIONS 

1.01.      Definitions. 
 (a)          Certain Definitions.  Capitalized terms not otherwise defined herein shall have the meanings given in the Credit Agreement.
In addition to the other terms defined elsewhere in this Agreement, as used herein the following terms shall have the following meanings: 

 “Guaranteed Obligations” shall mean all obligations from
time to time of the Borrower to the Lenders under or in connection with any Loan Document, whether for principal, interest, fees, indemnities, expenses or otherwise, and all refinancings or refundings thereof, whether such obligations are direct or
indirect, otherwise secured or unsecured, joint or several, absolute or contingent, due or to become due, whether for payment or performance, now existing or hereafter arising (specifically including but not limited to obligations arising or
accruing after the commencement of any bankruptcy, insolvency, reorganization or similar proceeding with respect to the Borrower or any other Person, or which would have arisen or accrued but for the commencement of such proceeding, even if the
claim for such obligation is not enforceable or allowable in such proceeding). Without limitation of the foregoing, such obligations include all obligations arising from any extensions of credit under or in connection with the Loan Documents from
time to time, regardless of whether any such extensions of credit are in excess of the amount committed under or contemplated by the Loan Documents or are made in circumstances in which any condition to extension of credit is not satisfied. Without
limitation of the foregoing, any of the Lenders (or any successive assignee or transferee) from time to time may assign or otherwise transfer all or any portion of their rights or obligations under the Loan Documents in accordance with
Section 10.14 of the Credit Agreement (including, without limitation, all or any portion of any commitment to extend credit), or any other Guaranteed Obligations, to any other Person, and such Guaranteed Obligations (including, without
limitation, any Guaranteed Obligations resulting from extension of credit by such other Person under or in connection with the Loan Documents) shall be and remain Guaranteed Obligations entitled to the benefit of the Credit Agreement. 

ARTICLE II 

GUARANTY AND SURETYSHIP 
 2.02.      Guaranty and Suretyship.  Each Guarantor hereby jointly and severally absolutely, unconditionally and irrevocably guarantees and becomes surety
for the full and punctual payment and performance of the Guaranteed Obligations as and when such payment or performance shall become due (at scheduled maturity, by acceleration or otherwise) in accordance with the terms of the Loan Documents. This
Agreement is an agreement of suretyship as well as of guaranty, is a guarantee of payment and performance and not merely of collectibility, and is in no way conditioned upon any attempt to collect from or proceed against the Borrower or any other
Person or any other event or circumstance. The obligations of the Guarantors under this Agreement are direct and primary obligations of each Guarantor and are independent of the Guaranteed Obligations, and a separate action or actions may be brought
against any Guarantor regardless of whether action is brought against the Borrower or any other Person or whether the Borrower or any other Person is joined in any such action or actions. 

2.03.      Obligations Absolute.  Each Guarantor agrees that the Guaranteed Obligations
will be paid and performed strictly in accordance with the terms of the Loan Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting the Guaranteed Obligations, any of the terms of the Loan
Documents or the rights of the Agent or any Lender or any other Person with respect thereto. The obligations of the Guarantors under 

 
this Agreement shall be absolute, unconditional and irrevocable, irrespective of any of the following: 
 (a)        any lack of legality, validity, enforceability, allowability (in a bankruptcy, insolvency, reorganization, dissolution or similar proceeding, or
otherwise), or any avoidance or subordination, in whole or in part, of any Loan Document or any of the Guaranteed Obligations; 

(b)        any change in the amount, nature, time, place or manner of payment or performance of,
or in any other term of, any of the Guaranteed Obligations (whether or not such change is contemplated by the Loan Documents as presently constituted, and specifically including any increase in the Guaranteed Obligations, whether resulting from the
extension of additional credit to the Borrower or otherwise), any execution of any additional Loan Documents or any amendment or waiver of or any consent to departure from any Loan Document; 

(c)        any taking, exchange, release, impairment or nonperfection of any collateral, or any
taking, release, impairment or amendment or waiver of or consent to departure from any other guaranty or other direct or indirect security for any of the Guaranteed Obligations; 

(d)        any manner of application of collateral or other direct or indirect security for any
of the Guaranteed Obligations, or proceeds thereof, to any of the Guaranteed Obligations, or any commercially reasonable manner of sale or other disposition of any collateral for any of the Guaranteed Obligations or any other assets of the Borrower;

 (e)        any permanent impairment by any Lender or any other Person of any
recourse of the Guarantor against the Borrower or any other Person, or any other permanent impairment by any Lender or any other Person of the suretyship status of the Guarantor; 

(f)        any bankruptcy, insolvency, reorganization, dissolution or similar proceedings with
respect to, or any change, restructuring or termination of the corporate structure or existence of, the Borrower, any Guarantor or any other Person; or 
 (g)        any failure of any Lender or any other Person to disclose to any Guarantor any information pertaining to the business, operations, condition (financial
or other) or prospects of the Borrower or any other Person, or to give any other notice, disclosure or demand. 

2.04.    Waivers, etc.  Each Guarantor hereby irrevocably waives any defense to or limitation on its
obligations under this Agreement arising out of or based upon any matter referred to in Section 2.2 and, without limiting the generality of the foregoing, any requirement of promptness, diligence or notice of acceptance, any other notice,
disclosure or demand with respect to any of the Guaranteed Obligations and this Agreement, any requirement of acceptance hereof, reliance hereon or knowledge hereof by the Agent or any Lender, and any requirement that the Agent or any Lender
protect, secure, perfect or insure any lien or any property subject thereto or exhaust any right or take any action against the Borrower or any other Person or any collateral or other direct or indirect security for any of the Guaranteed
Obligations. Notwithstanding the foregoing sentence, each Guarantor’s waiver under this Section 2.3 shall apply only to each Guarantor’s obligations hereunder and shall not limit or waive any of such Guarantor’s subrogation
rights. 

 2.05.    Reinstatement.  This Agreement shall continue
to be effective, or be automatically reinstated, as the case may be, if at any time payment of any of the Guaranteed Obligations is avoided, rescinded or must otherwise be returned by the Agent or any Lender for any reason, all as though such
payment had not been made. 
 2.06.    No Stay.  Without limiting the generality of any
other provision of this Agreement, if any acceleration of the time for payment or performance of any Guaranteed Obligation, or any condition to any such acceleration, shall at any time be stayed, enjoined or prevented for any reason (including stay
or injunction resulting from the pendency against the Borrower or any other Person of a bankruptcy, insolvency, reorganization, dissolution or similar proceeding), each Guarantor agrees that, for purposes of this Agreement and its obligations
hereunder, at the option of the Agent such Guaranteed Obligation shall be deemed to have been accelerated and such condition to acceleration shall be deemed to have been met. 
 2.07.    Payments.  All payments to be made by the Guarantors pursuant to this Agreement shall be made at the times and in the manner prescribed for payments in
Articles II and III of the Credit Agreement, without setoff, counterclaim, withholding or other deduction of any nature. All payments made by the Guarantors pursuant to this Agreement may be applied to the Guaranteed Obligations and all other
amounts payable under this Agreement in such order as the Agent may elect. 
 2.08.    Subrogation.
Etc.  Any rights which any Guarantor may have or acquire by way of subrogation, reimbursement, restitution, exoneration, contribution or indemnity, and any similar rights (whether arising by operation of law, by agreement or
otherwise), against the Borrower arising from the existence, payment, performance or enforcement of any of the obligations of any Guarantor under or in connection with this Agreement, shall be subordinate in right of payment to the Guaranteed
Obligations, and the Guarantors shall not exercise any such rights until all Guaranteed Obligations and all other obligations under this Agreement have been paid in cash or such other manner as may be acceptable to the Agent and performed in full
and all commitments to extend credit under, and all Letters of Credit issued under, the Loan Documents shall have terminated. If, notwithstanding the foregoing, any amount shall be received by any Guarantor on account of any such rights at any time
prior to the time at which all Guaranteed Obligations and all other obligations under this Agreement shall have been paid in cash or such other manner as may be acceptable to the Agent and performed in full and all commitments to extend credit
under, and all Letters of Credit issued under, the Loan Documents shall have terminated, such amount shall be held by such Guarantor in trust for the benefit of the Lenders, segregated from other funds held by such Guarantor, and shall be forthwith
delivered to Agent for the benefit of the Lenders in the exact form received by such Guarantor (with any necessary endorsement), to be applied to the Guaranteed Obligations, whether matured or unmatured, in such order as the Agent may elect, or to
be held by the Agent as security for the Guaranteed Obligations and disposed of by the Agent in any lawful manner, all as the Agent may elect. 

 2.09.    Continuing Agreement.  This Agreement is a
continuing guaranty and shall continue in full force and effect until all Guaranteed Obligations and all other amounts payable under this Agreement have been paid in cash or such other manner as may be acceptable to the Agent and performed in full,
and all commitments to extend credit under, and all Letters of Credit issued under, the Loan Documents have terminated, subject in any event to reinstatement in accordance with Section 2.4. Without limiting the generality of the foregoing, each
Guarantor hereby irrevocably waives any right to terminate or revoke this Agreement. 

2.10.    Limitation on Obligations.  Notwithstanding any other provision hereof, to the extent that
mandatory and nonwaivable provisions of applicable Law pertaining to fraudulent transfer or fraudulent conveyance otherwise would render the full amount of the obligations of the Guarantors under this Agreement avoidable, invalid or unenforceable,
the obligations of each Guarantor under this Agreement shall be limited to the maximum amount which does not result in such avoidability, invalidity or unenforceability. In any action, suit or proceeding pertaining to this Agreement, the burden of
proof, by clear and convincing evidence, shall be on the Person claiming that this Section 2.9 applies to limit any obligation of any Guarantor under this Agreement, or claiming that any obligation of any Guarantor under this Agreement is
avoidable, invalid or unenforceable, as to each element of such claim. 
 ARTICLE III 

REPRESENTATIONS AND WARRANTIES 
 Each Guarantor hereby jointly and severally represents and warrants to the Agent and the Lenders as follows: 
 3.11.    Credit Agreement.  The provisions of Article IV of the Credit Agreement are hereby incorporated by reference (together with all related definitions and cross
references). Each Guarantor hereby jointly and severally represents and warrants to the Agent and the Lenders as provided therein. 
 3.12.    Representations and Warranties Remade at Each Extension of Credit.  Each request (including any deemed request) by the Borrower for any extension of credit
under any Loan Document shall be deemed to constitute a representation and warranty by the Guarantors to the Agent and the Lenders that the representations and warranties made by the Guarantors in this Article III are true and correct on and as of
the date of such request with the same effect as though made on and as of such date. Failure by the Agent to receive notice from any Guarantor to the contrary before the Lenders make any extension of credit under any Loan Document shall constitute a
further representation and warranty by the Guarantors to the Agent and the Lenders that the representations and warranties made by the Guarantors in this Article III are true and correct on and as of the date of such extension of credit with the
same effect as though made on and as of such date. 
 ARTICLE IV 

COVENANTS 

4.13.    Covenants Generally.  Reference is hereby made to the provisions of Articles VI and VII of
the Credit Agreement (together with all related definitions and cross references). To 

 
the extent such provisions impose upon the Borrower a duty to cause any Guarantor (or a Subsidiary of each Guarantor) to do or refrain from doing certain acts or things or to meet or refrain from
meeting certain conditions, each Guarantor shall (or shall cause such Subsidiary of such Guarantor to, as the case may be) do or refrain from doing such acts or things, or meet or refrain from meeting such conditions, as the case may be. 

ARTICLE V 

MISCELLANEOUS 

5.14.    Amendments, etc.  No amendment to or waiver of any provision of this Agreement, and no
consent to any departure by any Guarantor herefrom, shall in any event be effective unless in a writing manually signed by or on behalf of each Lender and each Guarantor; provided that this Agreement may be terminated and any Guarantor or Guarantors
may be released herefrom with the written consent of the Required Lenders in connection with the sale or other disposition of all of the capital stock of and other equity interests in such Guarantor to a Person or Persons other than the Borrower or
a Subsidiary of the Borrower, which sale or other disposition is in compliance with the Credit Agreement and the Loan Documents. Any such waiver or consent shall be effective only in the specific instance and for the specific purpose for which
given. 
 5.15.    No Implied Waiver: Remedies Cumulative.  No delay or failure of the
Agent or any Lender in exercising any right or remedy under this Agreement shall operate as a waiver thereof; nor shall any single or partial exercise of any such right or remedy preclude any other or further exercise thereof or the exercise of any
other right or remedy. The rights and remedies of the Agent and the Lenders under this Agreement are cumulative and not exclusive of any other rights or remedies available hereunder, under any other agreement, at law, or otherwise. 

5.16.    Notices.  Except to the extent, if any, otherwise expressly provided herein, all notices
and other communications (collectively, “notices”) under this Agreement shall be in writing and shall be sent in the manner provided in Section 10.05 of the Credit Agreement. All notices shall be sent to the address specified in the
Credit Agreement for the applicable party, or, in any case, to such other address as shall have been designated by the applicable party by notice to the other party hereto. Any properly given notice shall be effective as provided in
Section 10.05 of the Credit Agreement. The Agent and the Lenders may rely on any notice (whether or not made in a manner contemplated by this Agreement) purportedly made by or on behalf of a Guarantor, and Agent and the Lenders shall have no
duty to verify the identity or authority of the Person giving such notice. 

5.17.    Expenses.  Each Guarantor agrees to pay upon demand all reasonable expenses (including
reasonable fees and expenses of counsel) which the Agent or any Lender may incur from time to time arising from or relating to the administration of, or exercise, enforcement or preservation of rights or remedies under, this Agreement, other than
costs and expenses incurred by the Agent or any Lender, respectively, in connection with any litigation which results in a final, non-appealable judgment against the Agent or such Lender. 

 5.18.    Entire Agreement.  This Agreement constitutes
the entire agreement of the parties hereto with respect to the subject matter hereof and supersedes all prior and contemporaneous understandings and agreements. 
 5.19.    Survival.  All representations and warranties of the Guarantors contained in or made in connection with this Agreement shall survive, and shall not be waived
by, the execution and delivery of this Agreement, any investigation by or knowledge of the Agent or any Lender, any extension of credit or any other event or circumstance whatever. 

5.20.    Counterparts.  This Agreement may be executed in any number of counterparts, including
facsimile counterparts, each of which shall be deemed an original, and all such counterparts shall constitute but one and the same agreement. 
 5.21.    Setoff.  In the event that any obligation of any Guarantor now or hereafter existing under this Agreement or any other Loan Document shall have become due and
payable, after an Event of Default under the Loan Documents has occurred, each Lender shall have the right from time to time, without notice to such Guarantor, to set off against and apply to such due and payable amount any obligation of any nature
of each Lender to the Guarantor, including all deposits (whether time or demand, general or special, provisionally or finally credited, however evidenced) now or hereafter maintained by such Guarantor with such Lender. Such right shall be absolute
and unconditional in all circumstances and, without limitation, shall exist whether such obligation to such Guarantor is absolute or contingent, matured or unmatured (it being agreed that each Lender may deem such obligation to be then due and
payable at the time of such setoff), regardless of the offices or branches through which the parties are acting with respect to the offset obligations, regardless of whether the offset obligations are denominated in the same or different currencies
and regardless of the existence or adequacy of any other direct or indirect security or any other right or remedy available to such Lender. Nothing in this Agreement or any other Loan Document shall be deemed a waiver of or restriction on any right
of setoff or banker’s lien available to any Lender under this Section 5.8, at law or otherwise. Each Guarantor hereby agrees that any affiliate of any Lender, and any holder of a participation in any Guaranteed Obligations of any Guarantor
under this Agreement, shall have the same rights of setoff as each Lender as provided in this Section 5.8 (regardless of whether such affiliate or participant otherwise would be deemed a creditor of such Guarantor). 

5.22.    Construction.  In this Agreement, unless the context otherwise clearly requires, references
to the plural include the singular, the singular the plural and the part the whole; the neuter case includes the masculine and feminine cases; and “or” is not exclusive. In this Agreement, any references to property (or similar terms)
include any interest in such property (or other item referred to); “include,” “includes,” “including” and similar terms are not limiting; and “hereof,” “herein,” “hereunder” and similar
terms refer to this Agreement as a whole and not to any particular provision; Section and other headings in this Agreement, and any table of contents herein, are for reference purposes only and shall not affect the interpretation of this Agreement
in any respect. Section and other references in this Agreement are to this Agreement unless otherwise specified. This Agreement has been fully negotiated between the applicable parties, each party having the benefit of legal counsel, and accordingly
neither any doctrine of construction of guaranties or suretyships in favor of the guarantor or surety, nor any doctrine of 

 
construction of ambiguities against the party controlling the drafting, shall apply to this Agreement. 
 5.23.    Successors and Assigns.  This Agreement shall be binding upon each Guarantor, its successors and assigns, and shall inure to the benefit of and be enforceable
by the Agent, the Lenders and their respective successors and assigns. Without limitation of the foregoing, the Agent or any Lender (and any successive assignee or transferee) from time to time may assign or otherwise transfer all or any portion of
its rights or obligations under the Loan Documents (including all or any portion of any commitment to extend credit), or any Guaranteed Obligations, to any other Person, and such Guaranteed Obligations (including any Guaranteed Obligations resulting
from extension of credit by such other Person under or in connection with the Loan Documents) shall be and remain Guaranteed Obligations entitled to the benefit of this Agreement, and to the extent of its interest in such Guaranteed Obligations such
other Person shall be vested with all the benefits in respect thereof granted to the Agent or any Lender, as the case may be, in this Agreement or otherwise. 
 5.24.     Certain Legal Matters. 

(a)        Governing Law.  This Agreement shall be governed by and construed in
accordance with the laws of the Commonwealth of Pennsylvania, exclusive of choice of law principles. 

(b)        Submission to Jurisdiction and Venue; Consent to Service of Process; Waiver of
Jury Trial; Etc.  Each Guarantor hereby irrevocably and unconditionally: 

(i)        agrees that any action, suit or proceeding by any Person arising from
or relating to this Agreement or any other Loan Document or any statement, course of conduct, act, omission or event in connection with any of the foregoing (collectively, “Related Litigation”) may be brought in any state or federal court
of competent jurisdiction sitting in Allegheny County, Pennsylvania, submits to the jurisdiction of such courts, and agrees not to bring any Related Litigation in any other forum (but nothing herein shall affect the right of the Agent or any Lender
to bring any Related Litigation in any other forum); 

(ii)       acknowledges that such courts will be the most convenient forum for any
Related Litigation, waives any objection to the laying of venue of any Related Litigation brought in any such court, waives any claim that any Related Litigation brought in any such court has been brought in an inconvenient forum and waives any
right to object, with respect to any Related Litigation, that such court does not have jurisdiction over it; 

(iii)      consents and agrees to service of any summons, complaint or other legal process
in any Related Litigation by registered or certified U.S. mail, postage prepaid, to it at the address for notices described in this Agreement, and consents and agrees that such service shall constitute in every respect valid and effective service
(but nothing herein shall affect the validity or effectiveness of process served in any other manner permitted by law); and 

 (iv)      waives the right to trial by jury
in any Related Litigation. 
 (c)        Limitation of Liability. No claim
may be made by any Guarantor against the Agent or any Lender or any affiliate, director, officer, employee, attorney or agent of the Agent or any Lender for any special, indirect, consequential or punitive damages in respect of any claim arising
from or relating to this Agreement or any other Loan Document or any statement, course of conduct, act, omission or event in connection with any of the foregoing (whether based on breach of contract, tort or any other theory of liability); and each
Guarantor hereby waives, releases and agrees not to sue upon any claim for any such damages, whether or not accrued and whether or not known or suspected to exist. 
 Each Guarantor acknowledges that it has been represented by legal counsel in connection with the execution and delivery of this Agreement and that it understands the provisions of this Agreement.

 EXHIBIT F 
 to Credit Agreement 
 SUBORDINATION TERMS 

Indebtedness incurred by a Loan Party from any Affiliate (except to the extent that any such requirement applied to a foreign Subsidiary
of a Loan Party could have an adverse tax consequence on any Loan Party) must be evidenced by an instrument or instruments containing, or referring to an agreement governing such instrument or instrument of indebtedness which contains, subordination
provisions substantially the same as those set forth below. Capitalized terms used and not otherwise defined herein shall have the meanings ascribed to such terms in the Credit Agreement to which this Exhibit F is attached and of which it is made a
part (the “Credit Agreement”). 
 1.         The payment of any
and all Subordinated Debt (as defined below) shall be expressly junior and subordinated, to the extent and in the manner set forth in paragraphs 2 through 12, inclusive, (except to the extent that any such requirement applied to a foreign Subsidiary
of a Loan Party could have an adverse tax consequence on any Loan Party) to any and all Senior Debt (as defined below) and to interest on Senior Debt at the rate stated in the instrument evidencing Senior Debt from the date of filing of any petition
under the Bankruptcy Code to the date of payment whether or not such interest is an allowed claim enforceable against the debtor in a bankruptcy case under applicable law (herein called “Post-petition Interest”). 

“Subordinated Debt” shall mean and include the principal of and interest and premium, if any, on all liabilities of the
[Company] [Guarantor] to [name of lender] (the “Subordinated Lender”), direct or contingent, joint, several or independent, now or hereafter existing, due or to become due to, or held or to be held by, the Subordinated Lender,
whether created directly or acquired by assignment or otherwise, including, without limiting the generality of the foregoing, [insert description of Subordinated Debt] and any fees or expenses of collection incurred by such Subordinated Lender.

 “Senior Debt” shall mean and include all obligations from time to time of the Borrower to the Lenders under
or in connection with any Loan Document, whether for principal, interest, fees, indemnities, expenses or otherwise, and all refinancings or refundings thereof, whether such obligations are direct or indirect, otherwise secured or unsecured, joint or
several, absolute or contingent, due or to become due, now existing or hereafter arising, including without limitation all obligations arising from any extensions of credit under or in connection with the Loan Documents from time to time, regardless
of whether any such extensions of credit are in excess of the amount committed under or contemplated by the Loan Documents or are made in circumstances in which any condition to extension of credit is not satisfied. 

2.         If an Event of Default or Potential Default, as defined in Section 1.01 of
the Credit Agreement, shall have occurred or would result from the making of any payment in respect of Subordinated Debt, the Subordinated Lender will not receive or accept any payment from the [Company] [Guarantor] in respect of Subordinated Debt,
unless and until such Event of Default or Potential Default shall have been cured, or unless and until Senior Debt and Post-petition Interest, if any, shall be paid in full. 

 3.         In the event the Subordinated
Lender shall receive any payment on Subordinated Debt which the Subordinated Lender is not entitled to receive under the provisions of paragraph 2 above, the Subordinated Lender will hold any amount so received in trust for the Lenders and will
forthwith turn over such payment to the Agent for the benefit of the Lenders in the form received to be applied on Senior Debt and Post-petition Interest, if any. In the event of the failure of any Subordinated Lender to endorse or assign any such
payment, distribution or security, the Agent and the Agent’s representative is hereby irrevocably authorized to endorse or assign the same. 
 4.         The Subordinated Lender will not commence any action or proceeding against the [Company] [Guarantor] to recover all or any part of the Subordinated
Debtor join, with any creditor, unless the Agent, for the benefit of the Lenders shall also join in bringing any proceedings against the [Company] [Guarantor] under any bankruptcy, reorganization, readjustment of debt, arrangement of debt,
receivership, liquidation or insolvency law or statute of the federal or any state government unless and until Senior Debt and Post-petition Interest, if any, shall be paid in full. 

5.         In the event of any liquidation, dissolution or other winding up of the
[Company] [Guarantor], or in the event of any receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization or arrangement with creditors, whether or not pursuant to bankruptcy laws, sale of all or substantially all
of the assets or any other marshalling of the assets and liabilities of the [Company] [Guarantor], (i) Senior Debt and Post-petition Interest, if any, shall first be paid in full before the Subordinated Lender shall be entitled to receive any
moneys, dividends or other assets in any such proceeding, and (ii) the Subordinated Lender will at the request of the Agent, file any claim, proof of claim or other instrument of similar character necessary to enforce the obligations of the
[Company] [Guarantor] in respect of Subordinated Debt and will hold in trust for Agent and the Lenders and pay over to the Agent for the benefit of the Lenders, in the form received, to be applied on Senior Debt and Post-petition Interest, any and
all moneys, dividends or other assets received in any proceeding on account of Subordinated Debt, unless and until Senior Debt and Post-petition Interest shall be paid in full. In the event the Subordinated Lender shall fail to take such action
requested by the Agent, the Agent may as attorney-in-fact for the Subordinated Lender, take such action on behalf of the Subordinated Lender, and the Subordinated Lender appoints the Lender as attorney-in-fact for the Subordinated Lender to demand,
sue for, collect and receive any and all such moneys, dividends or other assets and give acquittance therefor and to file any claim, proof of claim or other instrument of similar character and to take such other action (including acceptance or
rejection of any plan of reorganization or arrangement) in the name of the Agent and the Lenders or in the name of the Subordinated Lender as the Agent may deem necessary or advisable for the enforcement of these subordination terms; and the
Subordinated Lender will execute and deliver to the Agent for the benefit of the Lenders such other and further powers of attorney or other instruments as the Agent may request in order to accomplish the foregoing. 

6.         To the extent that the [Company] [Guarantor] or any other Person makes any
payment on the Senior Debt that is subsequently invalidated, declared to be fraudulent or preferential or set aside or is required to be repaid to a trustee, receiver or any other party under any bankruptcy, insolvency or reorganization act, state
or federal law, common law or equitable cause (such payment being hereinafter referred to as a “Voided Payment”), then to the extent of 

 
such Voided Payment, that portion of the Senior Debt that had been previously satisfied by such Voided Payment shall be revived and continue in full force and effect as if such Voided Payment had
never been made. In the event that a Voided Payment is recovered from the Lenders, an Event of Default shall be deemed to have existed and to be continuing under the Loan Documents from the date of the Agent’s initial receipt of such Voided
Payment until the full amount of such Voided Payment is restored to the Lenders. During any continuance of any such Event of Default, these subordination terms shall be in full force and effect with respect to the Subordinated Debt. To the extent
that the Subordinated Lender has received any payments with respect to the Subordinated Debt subsequent to the date of the Agent’s initial receipt of such Voided Payment and such payments have not been invalidated, declared to be fraudulent or
preferential or set aside or are required to be repaid to a trustee, receiver, or any other party under any bankruptcy act, state or federal law, common law or equitable cause, the Subordinated Lender shall be obligated and hereby agrees that any
such payment so made or received shall be deemed to have been received in trust for the benefit of the Lenders, and the Subordinated Lender shall pay to the Agent for the benefit of the Lenders, upon demand, the full amount so received by the
Subordinated Lender during such period of time to the extent necessary fully to restore to the Lenders the amount of such Voided Payment. 
 7.         Any holder of the Senior Debt may, at any time and from time to time, without the consent of or notice to the Subordinated Lender, without incurring
responsibility to the Subordinated Lender, and without impairing or releasing the rights of any of the holders of the Senior Debt, or any of the obligations of the Subordinated Lender hereunder: 

(a)        change the amount, manner, place or terms of payment or change or extend the time of
payment of or renew or alter Senior Debt or amend the Loan Documents in any manner or enter into or amend in any manner any other agreement relating to Senior Debt (including provisions restricting or further restricting payments of principal of and
interest on Subordinated Debt); 
 (b)        sell, exchange, release or otherwise deal
with any property by whomsoever at any time pledged or mortgaged to secure, or howsoever securing, Senior Debt; 

(c)        release anyone liable in any manner for the payment or collection of Senior Debt,
including any Person who may have guaranteed the Senior Debt; 
 (d)        exercise or
refrain from exercising any rights against the Borrower and others (including the Subordinated Lender); and 

(e)        apply any sums by whomsoever paid or however realized to Senior Debt. 

8.         Notice of acceptance of these subordination terms shall be waived by the
Subordinated Lender. 
 9.         The [Company] [Guarantor] and Subordinated
Lender will cause all Subordinated Debt to be evidenced by a note or other instrument which shall bear upon its face a statement or legend to the effect that such note or other instrument is subordinated to Senior Debt in the manner and to the
extent set forth in these subordination terms, and will mark its books to show that the Subordinated Debt is so subordinated to Senior Debt. 

 10.       Prior to the incurrence of any Subordinated
Debt the Subordinated Lender will execute and deliver to the Agent an agreement in form and substance satisfactory to the Agent evidencing the Subordinated Lender’s agreement to the foregoing terms. Such agreement shall include, without
limitation, a representation that neither the execution nor delivery of such agreement nor fulfillment nor compliance with the terms and provisions thereof shall conflict with, or result in a breach of the terms, conditions or provisions of, or
constitute a default under, any agreement or instrument to which the Subordinated Lender is subject and none of the Subordinated Debt will, at the time of incurrence thereof or at any time thereafter be subordinated to any Indebtedness of the
Borrower other than Senior Debt. 
 11.       So long as any of the Senior Debt shall not
have been paid in full, the [Company] [Guarantor] shall not, and shall not permit any of its subsidiaries to, give and the holders of the Subordinated Debt shall not demand, accept or receive any security, direct or indirect, for any Subordinated
Debt. 
 12.       None of the above paragraphs, nor any term thereof, may be changed or
waived except with the prior written consent of the holders of all the Senior Debt at the time outstanding. No Subordinated Debt or any term thereof may be changed, waived or cancelled in any manner which would have any adverse effect upon the right
of the holders of Senior Debt at the time outstanding.

the subcontract. This action is in the preliminary stages of litigation as NextiraOne Federal, LLC is attempting to move the action from bankruptcy court to federal district court. As of the date of this Agreement, the Borrower believes that
NextiraOne Federal, LLC d/b/a Black Box Network Services has meritorious defenses to this claim, although no assurance can be given as to the ultimate outcome in this matter.

9.          Javier Cobilich vs. Williams Communications Solutions, LLC (now NextiraOne, LLC);
National Union Fire Insurance Co.  This is a workers’ compensation case pending in the State of California. The applicant, Mr. Cobilich, alleges three (3) separate injuries. A trial on this case was held on
September 15, 2011. The court has ruled that the Applicant is entitled to future medical care but is not entitled to the services of a home health care attendant. These findings could be appealed by either party. The court has not ruled on the
Applicant’s entitlement to lost wages resulting from his injuries. There are three (3) injuries involved in this case that occurred at various times and that involve various insurance policies and carriers with varying policy deductibles.
There also exists the possibility for an indemnity claim by the Borrower against the party from whom the Borrower purchased NextiraOne, LLC.

held by third parties. Generally, all of such products are manufactured for the Subsidiaries by its vendors and the Subsidiaries would have claims against such vendors should any such patent infringement allegations be proven. In addition, if the
alleged infringement arises with respect to a company purchased by the Borrower and/or its Subsidiaries from a third party, there may be indemnification claims against such third party should any such patent infringement allegations be proven. As of

 GUARANTY AND SURETYSHIP AGREEMENT 
 THIS GUARANTY AND SURETYSHIP AGREEMENT (this
“Agreement”), dated as of the 23rd day of March, 2012, is made by the Guarantors identified as such on the signature page hereof (each, a “Guarantor” and, collectively, the “Guarantors”), to the lenders parties to the
Credit Agreement (as defined below) from time to time (the “Lenders”) and CITIZENS BANK OF PENNSYLVANIA, a banking association organized under the laws of the Commonwealth of Pennsylvania, as agent for the Lenders (in such capacity,
together with its successors in such capacity, the “Agent”). 
 W I T N E S
S E T H: 
 WHEREAS, the Guarantors, Black Box Corporation, a Delaware corporation
(“Borrower”), the Lenders and the Agent entered into that certain Credit Agreement, dated as of March 23, 2012 (as the same may be amended, restated, modified or supplemented from time to time, the “Credit Agreement”),
pursuant to which the Lenders made a revolving credit facility available to Borrower; and 
 WHEREAS, the Guarantors will derive
substantial direct and indirect benefit from the transactions contemplated by the Credit Agreement; and 
 WHEREAS, it is a
condition precedent to the extension of credit under the Credit Agreement that the Guarantors execute and deliver this Agreement; and 
 WHEREAS, this Agreement, among other things, is made by the Guarantors to induce the Lenders to enter into the Loan Documents (as defined in the Credit Agreement) and to induce the Lenders to extend
credit under the Credit Agreement. 
 NOW, THEREFORE, in consideration of the premises and other good and valuable
consideration, the receipt of which is hereby acknowledged by each Guarantor, and intending to be legally bound, each Guarantor hereby agrees as follows: 
 ARTICLE I. 
 DEFINITIONS 

1.1 Definitions. 
 (a)        Certain Definitions.  Capitalized terms not otherwise defined herein shall have the meanings given in the Credit Agreement. In addition
to the other terms defined elsewhere in this Agreement, as used herein the following terms shall have the following meanings: 
    “Guaranteed Obligations” shall mean all obligations from time to time of the Borrower to the Lenders under or in connection with any Loan Document, whether for
principal, interest, fees, indemnities, expenses or otherwise, and all refinancings or refundings thereof, whether such obligations are direct or indirect, otherwise secured or unsecured, joint or several, absolute or contingent, due or to become
due, whether for payment or performance, now existing or hereafter arising (specifically including but not 

 
limited to obligations arising or accruing after the commencement of any bankruptcy, insolvency, reorganization or similar proceeding with respect to the Borrower or any other Person, or which
would have arisen or accrued but for the commencement of such proceeding, even if the claim for such obligation is not enforceable or allowable in such proceeding). Without limitation of the foregoing, such obligations include all obligations
arising from any extensions of credit under or in connection with the Loan Documents from time to time, regardless of whether any such extensions of credit are in excess of the amount committed under or contemplated by the Loan Documents or are made
in circumstances in which any condition to extension of credit is not satisfied. Without limitation of the foregoing, any of the Lenders (or any successive assignee or transferee) from time to time may assign or otherwise transfer all or any portion
of their rights or obligations under the Loan Documents in accordance with Section 10.14 of the Credit Agreement (including, without limitation, all or any portion of any commitment to extend credit), or any other Guaranteed Obligations, to any
other Person, and such Guaranteed Obligations (including, without limitation, any Guaranteed Obligations resulting from extension of credit by such other Person under or in connection with the Loan Documents) shall be and remain Guaranteed
Obligations entitled to the benefit of the Credit Agreement. 
 ARTICLE II. 

GUARANTY AND SURETYSHIP 
 2.1 Guaranty and Suretyship.  Each Guarantor hereby jointly and severally absolutely, unconditionally and irrevocably guarantees and becomes surety for the full and punctual payment and
performance of the Guaranteed Obligations as and when such payment or performance shall become due (at scheduled maturity, by acceleration or otherwise) in accordance with the terms of the Loan Documents. This Agreement is an agreement of suretyship
as well as of guaranty, is a guarantee of payment and performance and not merely of collectibility, and is in no way conditioned upon any attempt to collect from or proceed against the Borrower or any other Person or any other event or circumstance.
The obligations of the Guarantors under this Agreement are direct and primary obligations of each Guarantor and are independent of the Guaranteed Obligations, and a separate action or actions may be brought against any Guarantor regardless of
whether action is brought against the Borrower or any other Person or whether the Borrower or any other Person is joined in any such action or actions. 
 2.2 Obligations Absolute.  Each Guarantor agrees that the Guaranteed Obligations will be paid and performed strictly in accordance with the terms of the Loan Documents, regardless of any
law, regulation or order now or hereafter in effect in any jurisdiction affecting the Guaranteed Obligations, any of the terms of the Loan Documents or the rights of the Agent or any Lender or any other Person with respect thereto. The obligations
of the Guarantors under this Agreement shall be absolute, unconditional and irrevocable, irrespective of any of the following: 

(a)        any lack of legality, validity, enforceability, allowability (in a bankruptcy,
insolvency, reorganization, dissolution or similar proceeding, or otherwise), or any avoidance or subordination, in whole or in part, of any Loan Document or any of the Guaranteed Obligations; 

  
 2 

 (b)        any change in the amount, nature, time,
place or manner of payment or performance of, or in any other term of, any of the Guaranteed Obligations (whether or not such change is contemplated by the Loan Documents as presently constituted, and specifically including any increase in the
Guaranteed Obligations, whether resulting from the extension of additional credit to the Borrower or otherwise), any execution of any additional Loan Documents or any amendment or waiver of or any consent to departure from any Loan Document;

 (c)        any taking, exchange, release, impairment or nonperfection of any
collateral, or any taking, release, impairment or amendment or waiver of or consent to departure from any other guaranty or other direct or indirect security for any of the Guaranteed Obligations; 

(d)        any manner of application of collateral or other direct or indirect security for any
of the Guaranteed Obligations, or proceeds thereof, to any of the Guaranteed Obligations, or any commercially reasonable manner of sale or other disposition of any collateral for any of the Guaranteed Obligations or any other assets of the Borrower;

 (e)        any permanent impairment by any Lender or any other Person of any
recourse of the Guarantor against the Borrower or any other Person, or any other permanent impairment by any Lender or any other Person of the suretyship status of the Guarantor; 

(f)        any bankruptcy, insolvency, reorganization, dissolution or similar proceedings with
respect to, or any change, restructuring or termination of the corporate structure or existence of, the Borrower, any Guarantor or any other Person; or 
 (g)        any failure of any Lender or any other Person to disclose to any Guarantor any information pertaining to the business, operations, condition (financial
or other) or prospects of the Borrower or any other Person, or to give any other notice, disclosure or demand. 
 2.3
Waivers, etc.  Each Guarantor hereby irrevocably waives any defense to or limitation on its obligations under this Agreement arising out of or based upon any matter referred to in Section 2.2 and, without limiting the
generality of the foregoing, any requirement of promptness, diligence or notice of acceptance, any other notice, disclosure or demand with respect to any of the Guaranteed Obligations and this Agreement, any requirement of acceptance hereof,
reliance hereon or knowledge hereof by the Agent or any Lender, and any requirement that the Agent or any Lender protect, secure, perfect or insure any lien or any property subject thereto or exhaust any right or take any action against the Borrower
or any other Person or any collateral or other direct or indirect security for any of the Guaranteed Obligations. Notwithstanding the foregoing sentence, each Guarantor’s waiver under this Section 2.3 shall apply only to each
Guarantor’s obligations hereunder and shall not limit or waive any of such Guarantor’s subrogation rights. 
 2.4
Reinstatement.  This Agreement shall continue to be effective, or be automatically reinstated, as the case may be, if at any time payment of any of the Guaranteed Obligations is avoided, rescinded or must otherwise be returned by
the Agent or any Lender for any reason, all as though such payment had not been made. 

  
 3 

 2.5 No Stay.  Without limiting the generality of any other provision of
this Agreement, if any acceleration of the time for payment or performance of any Guaranteed Obligation, or any condition to any such acceleration, shall at any time be stayed, enjoined or prevented for any reason (including stay or injunction
resulting from the pendency against the Borrower or any other Person of a bankruptcy, insolvency, reorganization, dissolution or similar proceeding), each Guarantor agrees that, for purposes of this Agreement and its obligations hereunder, at the
option of the Agent such Guaranteed Obligation shall be deemed to have been accelerated and such condition to acceleration shall be deemed to have been met. 
 2.6 Payments.  All payments to be made by the Guarantors pursuant to this Agreement shall be made at the times and in the manner prescribed for payments in Articles II and III of the
Credit Agreement, without setoff, counterclaim, withholding or other deduction of any nature. All payments made by the Guarantors pursuant to this Agreement may be applied to the Guaranteed Obligations and all other amounts payable under this
Agreement in such order as the Agent may elect. 
 2.7 Subrogation. Etc.  Any rights which any Guarantor may
have or acquire by way of subrogation, reimbursement, restitution, exoneration, contribution or indemnity, and any similar rights (whether arising by operation of law, by agreement or otherwise), against the Borrower arising from the existence,
payment, performance or enforcement of any of the obligations of any Guarantor under or in connection with this Agreement, shall be subordinate in right of payment to the Guaranteed Obligations, and the Guarantors shall not exercise any such rights
until all Guaranteed Obligations and all other obligations under this Agreement have been paid in cash or such other manner as may be acceptable to the Agent and performed in full and all commitments to extend credit under, and all Letters of Credit
issued under, the Loan Documents shall have terminated. If, notwithstanding the foregoing, any amount shall be received by any Guarantor on account of any such rights at any time prior to the time at which all Guaranteed Obligations and all other
obligations under this Agreement shall have been paid in cash or such other manner as may be acceptable to the Agent and performed in full and all commitments to extend credit under, and all Letters of Credit issued under, the Loan Documents shall
have terminated, such amount shall be held by such Guarantor in trust for the benefit of the Lenders, segregated from other funds held by such Guarantor, and shall be forthwith delivered to Agent for the benefit of the Lenders in the exact form
received by such Guarantor (with any necessary endorsement), to be applied to the Guaranteed Obligations, whether matured or unmatured, in such order as the Agent may elect, or to be held by the Agent as security for the Guaranteed Obligations and
disposed of by the Agent in any lawful manner, all as the Agent may elect. 
 2.8 Continuing Agreement.  This
Agreement is a continuing guaranty and shall continue in full force and effect until all Guaranteed Obligations and all other amounts payable under this Agreement have been paid in cash or such other manner as may be acceptable to the Agent and
performed in full, and all commitments to extend credit under, and all Letters of Credit issued under, the Loan Documents have terminated, subject in any event to reinstatement in accordance with Section 2.4. Without limiting the generality of
the foregoing, each Guarantor hereby irrevocably waives any right to terminate or revoke this Agreement. 

  
 4 

 2.9 Limitation on Obligations.  Notwithstanding any other provision hereof,
to the extent that mandatory and nonwaivable provisions of applicable Law pertaining to fraudulent transfer or fraudulent conveyance otherwise would render the full amount of the obligations of the Guarantors under this Agreement avoidable, invalid
or unenforceable, the obligations of each Guarantor under this Agreement shall be limited to the maximum amount which does not result in such avoidability, invalidity or unenforceability. In any action, suit or proceeding pertaining to this
Agreement, the burden of proof, by clear and convincing evidence, shall be on the Person claiming that this Section 2.9 applies to limit any obligation of any Guarantor under this Agreement, or claiming that any obligation of any Guarantor under
this Agreement is avoidable, invalid or unenforceable, as to each element of such claim. 
 ARTICLE III. 

REPRESENTATIONS AND WARRANTIES 
 Each Guarantor hereby jointly and severally represents and warrants to the Agent and the Lenders as follows: 
 3.1 Credit Agreement.  The provisions of Article IV of the Credit Agreement are hereby incorporated by reference (together with all related definitions and cross references). Each
Guarantor hereby jointly and severally represents and warrants to the Agent and the Lenders as provided therein. 
 3.2
Representations and Warranties Remade at Each Extension of Credit.  Each request (including any deemed request) by the Borrower for any extension of credit under any Loan Document shall be deemed to constitute a representation and
warranty by the Guarantors to the Agent and the Lenders that the representations and warranties made by the Guarantors in this Article III are true and correct on and as of the date of such request with the same effect as though made on and as of
such date. Failure by the Agent to receive notice from any Guarantor to the contrary before the Lenders make any extension of credit under any Loan Document shall constitute a further representation and warranty by the Guarantors to the Agent and
the Lenders that the representations and warranties made by the Guarantors in this Article III are true and correct on and as of the date of such extension of credit with the same effect as though made on and as of such date. 

ARTICLE IV. 

COVENANTS 
 4.1
Covenants Generally.  Reference is hereby made to the provisions of Articles VI and VII of the Credit Agreement (together with all related definitions and cross references). To the extent such provisions impose upon the Borrower a
duty to cause any Guarantor (or a Subsidiary of each Guarantor) to do or refrain from doing certain acts or things or to meet or refrain from meeting certain conditions, each Guarantor shall (or shall cause such Subsidiary of such Guarantor to, as
the case may be) do or refrain from doing such acts or things, or meet or refrain from meeting such conditions, as the case may be. 

  
 5 

 ARTICLE V. 
 MISCELLANEOUS 
 5.1 Amendments, etc.  No amendment to or waiver
of any provision of this Agreement, and no consent to any departure by any Guarantor herefrom, shall in any event be effective unless in a writing manually signed by or on behalf of each Lender and each Guarantor; provided that this Agreement may be
terminated and any Guarantor or Guarantors may be released herefrom with the written consent of the Required Lenders in connection with the sale or other disposition of all of the capital stock of and other equity interests in such Guarantor to a
Person or Persons other than the Borrower or a Subsidiary of the Borrower, which sale or other disposition is in compliance with the Credit Agreement and the Loan Documents. Any such waiver or consent shall be effective only in the specific instance
and for the specific purpose for which given. 
 5.2 No Implied Waiver: Remedies Cumulative.  No delay or
failure of the Agent or any Lender in exercising any right or remedy under this Agreement shall operate as a waiver thereof; nor shall any single or partial exercise of any such right or remedy preclude any other or further exercise thereof or the
exercise of any other right or remedy. The rights and remedies of the Agent and the Lenders under this Agreement are cumulative and not exclusive of any other rights or remedies available hereunder, under any other agreement, at law, or otherwise.

 5.3 Notices.  Except to the extent, if any, otherwise expressly provided herein, all notices and other
communications (collectively, “notices”) under this Agreement shall be in writing and shall be sent in the manner provided in Section 10.05 of the Credit Agreement. All notices shall be sent to the address specified in the Credit
Agreement for the applicable party, or, in any case, to such other address as shall have been designated by the applicable party by notice to the other party hereto. Any properly given notice shall be effective as provided in Section 10.05 of
the Credit Agreement. The Agent and the Lenders may rely on any notice (whether or not made in a manner contemplated by this Agreement) purportedly made by or on behalf of a Guarantor, and Agent and the Lenders shall have no duty to verify the
identity or authority of the Person giving such notice. 
 5.4 Expenses.  Each Guarantor agrees to pay upon
demand all reasonable expenses (including reasonable fees and expenses of counsel) which the Agent or any Lender may incur from time to time arising from or relating to the administration of, or exercise, enforcement or preservation of rights or
remedies under, this Agreement, other than costs and expenses incurred by the Agent or any Lender, respectively, in connection with any litigation which results in a final, non-appealable judgment against the Agent or such Lender. 

5.5 Entire Agreement.   This Agreement constitutes the entire agreement of the parties hereto with respect to the
subject matter hereof and supersedes all prior and contemporaneous understandings and agreements. 
 5.6
Survival.  All representations and warranties of the Guarantors contained in or made in connection with this Agreement shall survive, and shall not be waived by, the execution and delivery of this Agreement, any investigation by or
knowledge of the Agent or any Lender, any extension of credit or any other event or circumstance whatever. 

  
 6 

 5.7  Counterparts.  This Agreement may be executed in any number
of counterparts, including facsimile counterparts, each of which shall be deemed an original, and all such counterparts shall constitute but one and the same agreement. 
 5.8 Setoff.  In the event that any obligation of any Guarantor now or hereafter existing under this Agreement or any other Loan Document shall have become due and payable, after an Event
of Default under the Loan Documents has occurred, each Lender shall have the right from time to time, without notice to such Guarantor, to set off against and apply to such due and payable amount any obligation of any nature of each Lender to the
Guarantor, including all deposits (whether time or demand, general or special, provisionally or finally credited, however evidenced) now or hereafter maintained by such Guarantor with such Lender. Such right shall be absolute and unconditional in
all circumstances and, without limitation, shall exist whether such obligation to such Guarantor is absolute or contingent, matured or unmatured (it being agreed that each Lender may deem such obligation to be then due and payable at the time of
such setoff), regardless of the offices or branches through which the parties are acting with respect to the offset obligations, regardless of whether the offset obligations are denominated in the same or different currencies and regardless of the
existence or adequacy of any other direct or indirect security or any other right or remedy available to such Lender. Nothing in this Agreement or any other Loan Document shall be deemed a waiver of or restriction on any right of setoff or
banker’s lien available to any Lender under this Section 5.8, at law or otherwise. Each Guarantor hereby agrees that any affiliate of any Lender, and any holder of a participation in any Guaranteed Obligations of any Guarantor under this
Agreement, shall have the same rights of setoff as each Lender as provided in this Section 5.8 (regardless of whether such affiliate or participant otherwise would be deemed a creditor of such Guarantor). 

5.9 Construction.  In this Agreement, unless the context otherwise clearly requires, references to the plural include
the singular, the singular the plural and the part the whole; the neuter case includes the masculine and feminine cases; and “or” is not exclusive. In this Agreement, any references to property (or similar terms) include any interest in
such property (or other item referred to); “include,” “includes,” “including” and similar terms are not limiting; and “hereof,” “herein,” “hereunder” and similar terms refer to this
Agreement as a whole and not to any particular provision; Section and other headings in this Agreement, and any table of contents herein, are for reference purposes only and shall not affect the interpretation of this Agreement in any respect.
Section and other references in this Agreement are to this Agreement unless otherwise specified. This Agreement has been fully negotiated between the applicable parties, each party having the benefit of legal counsel, and accordingly neither any
doctrine of construction of guaranties or suretyships in favor of the guarantor or surety, nor any doctrine of construction of ambiguities against the party controlling the drafting, shall apply to this Agreement. 

5.10    Successors and Assigns.  This Agreement shall be binding upon each Guarantor, its successors
and assigns, and shall inure to the benefit of and be enforceable by the Agent, the Lenders and their respective successors and assigns. Without limitation of the foregoing, the Agent or any Lender (and any successive assignee or transferee) from
time to time may assign or otherwise transfer all or any portion of its rights or obligations under the Loan Documents (including all or any portion of any commitment to extend credit), or any Guaranteed Obligations, to any other Person, and such
Guaranteed Obligations (including any Guaranteed 

  
 7 

 
Obligations resulting from extension of credit by such other Person under or in connection with the Loan Documents) shall be and remain Guaranteed Obligations entitled to the benefit of this
Agreement, and to the extent of its interest in such Guaranteed Obligations such other Person shall be vested with all the benefits in respect thereof granted to the Agent or any Lender, as the case may be, in this Agreement or otherwise.

 5.11      Certain Legal Matters. 

(a)        Governing Law.  This Agreement shall be governed by and construed in
accordance with the laws of the Commonwealth of Pennsylvania, exclusive of choice of law principles. 

(b)        Submission to Jurisdiction and Venue; Consent to Service of Process; Waiver of
Jury Trial; Etc.  Each Guarantor hereby irrevocably and unconditionally: 

    (i)            agrees that any
action, suit or proceeding by any Person arising from or relating to this Agreement or any other Loan Document or any statement, course of conduct, act, omission or event in connection with any of the foregoing (collectively, “Related
Litigation”) may be brought in any state or federal court of competent jurisdiction sitting in Allegheny County, Pennsylvania, submits to the jurisdiction of such courts, and agrees not to bring any Related Litigation in any other forum (but
nothing herein shall affect the right of the Agent or any Lender to bring any Related Litigation in any other forum); 
    (ii)            acknowledges that such courts will be the most convenient forum for any Related Litigation, waives any
objection to the laying of venue of any Related Litigation brought in any such court, waives any claim that any Related Litigation brought in any such court has been brought in an inconvenient forum and waives any right to object, with respect to
any Related Litigation, that such court does not have jurisdiction over it; 

  (iii)            consents and agrees to service
of any summons, complaint or other legal process in any Related Litigation by registered or certified U.S. mail, postage prepaid, to it at the address for notices described in this Agreement, and consents and agrees that such service shall
constitute in every respect valid and effective service (but nothing herein shall affect the validity or effectiveness of process served in any other manner permitted by law); and 

  (iv)            waives the right to trial by
jury in any Related Litigation. 
 (c)        Limitation of
Liability.  No claim may be made by any Guarantor against the Agent or any Lender or any affiliate, director, officer, employee, attorney or agent of the Agent or any Lender for any special, indirect, consequential or punitive damages
in respect of any claim arising from or relating to this Agreement or any other Loan Document or any statement, course of conduct, act, omission or event in connection with any of the foregoing (whether based on breach of contract, tort or any other
theory of liability); and each Guarantor hereby waives, releases and agrees not to sue upon any claim for any such damages, whether or not accrued and whether or not known or suspected to exist.
