Whenever the words “including” or “include” shall be used, such words shall be understood to mean “including, without limitation” or “include, without limitation”. A Default or an Event of Default shall be deemed to exist at all times during the period commencing on the date that such Default or Event of Default occurs to the date on which such Default or Event of Default is waived in writing pursuant to this Agreement or, in the case of a Default, is cured within any period of cure expressly provided for in this Agreement; and an Event of Default shall “continue” or be “continuing” until such Event of Default has been waived in writing by Required Lenders. Any Lien referred to in this Agreement or any of the Other Documents as having been created in favor of Agent, any agreement entered into by Agent pursuant to this Agreement or any of the Other Documents, any payment made by or to or funds received by Agent pursuant to or as contemplated by this Agreement or any of the Other Documents, or any act taken or omitted to be taken by Agent, shall, unless otherwise expressly provided, be created, entered into, made or received, or taken or omitted, for the benefit or account of Agent and Lenders.

In addition, all representations and warranties hereunder shall be given independent effect so that if a particular representation or warranty proves to be incorrect or is breached, the fact that another representation or warranty concerning the same or similar subject matter is correct or is not breached will not affect the incorrectness of a breach of a representation or warranty hereunder.

(a)Amount of Revolving Advances. Subject to the terms and conditions set forth in this Agreement including Sections 2.1(b), each Revolving Lender, severally and not jointly, will make Revolving Advances to Borrowers in aggregate amounts outstanding at any time equal to such Revolving Lender’s Revolving Commitment Percentage of the lesser of (x) the Maximum Revolving Advance Amount as in effect at such time, less the outstanding amount of Swing Loans at such time, less the aggregate Maximum Undrawn Amount of all Letters of Credit outstanding at such time, less Reserves established hereunder as in effect at such time, less Ex-Im Reserves established under the Ex-Im Subfacility Credit Agreement as in effect at such time less the outstanding Ex-Im Subfacility Outstandings Amount at such time, or (y) an amount equal to the Dollar Equivalent of sum of:

(i)up to 85% of Eligible Receivables (including Eligible Foreign Receivables), plus

(iii)the Dollar Equivalent of the aggregate Maximum Undrawn Amount of all outstanding Letters of Credit, minus

(iv)Reserves established hereunder, specifically including but not limited to any reserves to reflect the risks, as determined by Agent in its Permitted Discretion, of currency exchange rate fluctuations with respect to any of the Approved Foreign Currencies in which the Eligible Receivables are denominated and/or any of the Approved LC Foreign Currencies in which any Foreign Currency Letters of Credit are denominated (provided that, no Reserve for currency exchange rate Reserves shall be established with respect to Eligible Receivables denominated in any Approved Foreign Currencies and/or Foreign Currency Letters of Credit to the extent that Borrowers have entered into appropriate Foreign Currency Hedges to protect against such risks).

The amount derived from the sum of (x) Sections 2.1(a)(y)(i) and (ii) above minus (y) Sections 2.1(a)(y)(iii) and (iv) above at any time and from time to time shall be referred to as the “Formula Amount”. The Revolving Advances shall be evidenced by one or more secured promissory notes (collectively, the “Revolving Credit Note”) substantially in the form attached hereto as Exhibit 2.1. Notwithstanding the foregoing or otherwise in this Agreement, (A) the aggregate principal amount of Swing Loans and the Revolving Advances at any one time outstanding plus the Dollar Equivalent of the Maximum Undrawn Amount of all Letters of Credit outstanding at such time shall not exceed the Total Domestic Borrowing Availability at such time, and (B) the aggregate principal amount of Swing Loans and the Revolving Advances at any one time outstanding plus the Dollar Equivalent of the Maximum Undrawn Amount of all Letters of Credit outstanding at such time, plus the Ex-Im Subfacility Outstandings Amount at such time shall not the Total Borrowing Availability at such time.

For purposes of calculating the Dollar Equivalent of the aggregate Maximum Undrawn Amount of all outstanding Foreign Currency Letters of Credit, the Formula Amount, the Total Domestic Borrowing Availability, the Total Borrowing Availability, or Ex-Im Subfacility Outstandings Amount at any time/as of any date for any purpose under this Agreement (including, without limitation, Sections 2.4, 2.7, 2.9, or 2.11(a) hereof) or the Ex-Im Subfacility Credit Agreement, the Dollar Equivalent of each Foreign Currency Letter of Credit and each Ex-Im Foreign Currency

Letter of Credit at such time/as of such date shall be the Dollar Equivalent of each such Foreign Currency Letter of Credit and each such Ex-Im Foreign Currency Letter of Credit as of the most recent Valuation Date.

(b)Discretionary Rights. The Advance Rates may be increased or decreased by Agent at any time and from time to time in the exercise of its Permitted Discretion. Each Borrower consents to any such increases or decreases and acknowledges that decreasing the Advance Rates or increasing or imposing Reserves may limit or restrict Advances requested by Borrowing Agent. The rights of Agent under this subsection are subject to the provisions of Section 16.2(b) hereof.

2.2Procedures for Requesting Revolving Advances; Procedures for Selection of Applicable Interest Rates for All Advances.

(a)Borrowing Agent on behalf of Borrowers may notify Agent prior to 2:00 p.m. on a Business Day of Borrowers’ request to incur, on that day, a Revolving Advance hereunder. Should any amount required to be paid as interest hereunder, or as fees or other charges under this Agreement or any other agreement with Agent or Lenders, or with respect to any other Obligation under this Agreement, become due, the same shall be deemed a request for a Revolving Advance maintained as a Domestic Rate Loan as of the date such payment is due, in the amount required to pay in full such interest, fee, charge or Obligation, and such request shall be irrevocable.

(b)Notwithstanding the provisions of subsection (a) above, in the event Borrowers desires to obtain a LIBOR Rate Loan for any Advance (other than a Swing Loan), Borrowing Agent shall give Agent written notice by no later than 2:00 p.m. on the day which is three (3) Business Days prior to the date such LIBOR Rate Loan is to be borrowed, specifying (i) the date of the proposed borrowing (which shall be a Business Day), (ii) the type of borrowing and the amount of such Advance to be borrowed, which amount shall be in a minimum amount of $500,000 and in integral multiples of $100,000 thereafter, and (iii) the duration of the first Interest Period therefor. Interest Periods for LIBOR Rate Loans shall be for one, two or three months; provided that, if an Interest Period would end on a day that is not a Business Day, it shall end on the next succeeding Business Day unless such day falls in the next succeeding calendar month in which case the Interest Period shall end on the next preceding Business Day. Any Interest Period that begins on the last Business Day of a calendar month (or a day for which there is no numerically corresponding day in the last calendar month of such Interest Period) shall end on the last Business Day of the last calendar month of such Interest Period. Upon and after the occurrence of an Event of Default, and during the continuation thereof, at the option of Agent or at the direction of the Required Lenders, no LIBOR Rate Loan shall be made available to any Borrower, and at Agent’s election, or the direction of the Required Lenders, and upon notice to Borrowing Agent, all LIBOR Rate Loans in effect during an Event of Default shall be converted to Domestic Rate Loans. After giving effect to each requested LIBOR Rate Loan, including those which are converted from a Domestic Rate Loan under Section 2.2(e), there shall not be outstanding more than three (3) Eurodollar Rate Loans, in the aggregate, under this Agreement or more than two (2) Eurodollar Rate Loans, in the aggregate, under the Ex-Im Subfacility Credit Agreement.

(c)Each Interest Period of a LIBOR Rate Loan shall commence on the date such LIBOR Rate Loan is made and shall end on such date as Borrowing Agent may elect as set forth in subsection (b)(iii) above, provided that the exact length of each Interest Period shall be

determined in accordance with the practice of the interbank market for offshore Dollar deposits and no Interest Period shall end after the last day of the Term.

(d)Borrowing Agent shall elect the initial Interest Period applicable to a LIBOR Rate Loan by its notice of borrowing given to Agent pursuant to Section 2.2(b) hereof or by its notice of conversion given to Agent pursuant to Section 2.2(e) hereof, as the case may be. Borrowing Agent shall elect the duration of each succeeding Interest Period by giving irrevocable written notice to Agent of such duration not later than 2:00 p.m. on the day which is three (3) Business Days prior to the last day of the then current Interest Period applicable to such LIBOR Rate Loan. If Agent does not receive timely notice of the Interest Period elected by Borrowing Agent, Borrowing Agent shall be deemed to have elected to convert such LIBOR Rate Loan to a Domestic Rate Loan as of the last day of the Interest Period applicable to such LIBOR Rate Loan subject to Section 2.2(e) below.

(e)Provided that no Default or Event of Default shall have occurred and be continuing, Borrowing Agent may, on the last Business Day of the then current Interest Period applicable to any outstanding LIBOR Rate Loan, or on any Business Day with respect to Domestic Rate Loans, convert any such loan into a loan of another type in the same aggregate principal amount provided that any conversion of a LIBOR Rate Loan shall be made only on the last Business Day of the then current Interest Period applicable to such LIBOR Rate Loan. If Borrowing Agent desires to convert a loan, Borrowing Agent shall give Agent written notice by no later than 2:00 p.m. (i) on the day which is three (3) Business Days prior to the date on which such conversion is to occur with respect to a conversion from a Domestic Rate Loan to a LIBOR Rate Loan, or (ii) on the day which is one (1) Business Day prior to the date on which such conversion is to occur (which date shall be the last Business Day of the Interest Period for the applicable LIBOR Rate Loan) with respect to a conversion from a LIBOR Rate Loan to a Domestic Rate Loan, specifying, in each case, the date of such conversion, the loans to be converted and if the conversion is to a LIBOR Rate Loan, the duration of the first Interest Period therefor.

(f)At its option and upon written notice given prior to 2:00 p.m. at least three (3) Business Days prior to the date of such prepayment, Borrowers may, subject to Section 2.2(g) and Section 2.20 hereof, prepay the LIBOR Rate Loans in whole at any time or in part from time to time with accrued interest on the principal being prepaid to the date of such repayment. Borrowers shall specify the date of prepayment of Advances which are LIBOR Rate Loans and the amount of such prepayment. In the event that any prepayment of a LIBOR Rate Loan is required or permitted on a date other than the last Business Day of the then current Interest Period with respect thereto, Borrowers shall indemnify Agent and Lenders therefor in accordance with Section 2.2(g) hereof.

(g)Each Borrower shall indemnify Agent and Lenders and hold Agent and Lenders harmless from and against any and all losses or expenses that Agent and Lenders may sustain or incur as a consequence of any prepayment, conversion of or any default by any Borrower in the payment of the principal of or interest on any LIBOR Rate Loan or failure by Borrowers to complete a borrowing of, a prepayment of or conversion of or to a LIBOR Rate Loan after notice thereof has been given, including, but not limited to, any interest payable by Agent or Lenders to lenders of funds obtained by it in order to make or maintain its LIBOR Rate Loans hereunder. A

certificate as to any additional amounts payable pursuant to the foregoing sentence submitted by Agent or any Lender to Borrowing Agent shall be conclusive absent manifest error.

(h)Notwithstanding any other provision hereof, if any Applicable Law, treaty, regulation or directive, or any change therein or in the interpretation or application thereof, including without limitation any Change in Law, shall make it unlawful for Lenders or any Lender (for purposes of this subsection (h), the term “Lender” shall include any Lender and the office or branch where any Lender or any Person controlling such Lender makes or maintains any LIBOR Rate Loans) to make or maintain its LIBOR Rate Loans, the obligation of Lenders (or such affected Lender) to make LIBOR Rate Loans hereunder shall forthwith be cancelled and Borrowers shall, if any affected LIBOR Rate Loans are then outstanding, promptly upon request from Agent, either pay all such affected LIBOR Rate Loans or convert such affected LIBOR Rate Loans into loans of another type. If any such payment or conversion of any LIBOR Rate Loan is made on a day that is not the last day of the Interest Period applicable to such LIBOR Rate Loan, Borrowers shall pay Agent, upon Agent’s request, such amount or amounts set forth in clause (g) above. A certificate as to any additional amounts payable pursuant to the foregoing sentence submitted by Lenders to Borrowing Agent shall be conclusive absent manifest error.

(i)Anything to the contrary contained herein notwithstanding, neither any Agent nor any Lender, nor any of their participants, is required actually to acquire LIBOR deposits to fund or otherwise match fund any Obligation as to which interest accrues based on the LIBOR Rate. The provisions set forth herein shall apply as if each Lender or its participants had match funded any Obligation as to which interest is accruing based on the LIBOR Rate by acquiring LIBOR deposits for each Interest Period in the amount of the LIBOR Rate Loans.

2.3Term Loan. Subject to the terms and conditions of this Agreement, each Term Loan Lender, severally and not jointly, will make a term loan advance to Borrowers in the amount equal to such Lender’s Term Loan Commitment Percentage of the Total Term Loan Commitment Amount (all such advances, collectively, the “Term Loan”). The Term Loan shall be advanced on the Closing Date and shall be, with respect to principal, payable as follows, subject to acceleration upon the occurrence of an Event of Default under this Agreement or termination of this Agreement:

The Term Loan shall be evidenced by one or more secured promissory notes (collectively, the “Term Loan Note”) in substantially the form attached hereto as Exhibit 2.3(a) to the extent requested by the applicable Lender. The Term Loan and any portion(s) thereof may consist of Domestic Rate Loans or LIBOR Rate Loans, or a combination thereof, as Borrowing Agent may request; and in the event that Borrowers desire to obtain or extend any portion of the Term Loan as a LIBOR Rate Loan or to convert any portion of the Term Loan from a Domestic Rate Loan to a LIBOR Rate Loan, Borrowing Agent shall comply with the notification requirements set forth in Sections 2.2(b) and/or (e) hereof and the provisions of Sections 2.2(b) through (i) hereof shall apply.

(a)Subject to the terms and conditions set forth in this Agreement, and in order to minimize the transfer of funds between Revolving Lenders and Agent for administrative convenience, Agent, Revolving Lenders and Swing Loan Lender agree that in order to facilitate the administration of this Agreement, Swing Loan Lender may, at its election and option made in its sole discretion cancelable at any time for any reason whatsoever, make swing loan advances (“Swing Loans”) available to Borrowers as provided for in this Section 2.4 at any time or from time to time after the Closing Date to, but not including, the last day of the Term, in an aggregate principal amount up to but not in excess of the Maximum Swing Loan Advance Amount, provided that the aggregate principal amount of Swing Loans and the Revolving Advances at any one time outstanding shall not exceed an amount equal to the lesser of (i) the Maximum Revolving Advance Amount less the Maximum Undrawn Amount of all outstanding Letters of Credit less Reserves established hereunder as in effect at such time less Ex-Im Reserves established under the Ex-Im Credit Agreement as in effect at such time less the Ex-Im Subfacility Outstandings Amount at such time, or (ii) the Formula Amount as in effect at such time. All Swing Loans shall be Domestic Rate Loans only. Borrowers may borrow (at the option and election of Swing Loan Lender), repay and reborrow (at the option and election of Swing Loan Lender) Swing Loans and Swing Loan Lender may make Swing Loans as provided in this Section 2.4 during the period between Settlement Dates. All Swing Loans shall be evidenced by a secured promissory note (the “Swing Loan Note”) substantially in the form attached hereto as Exhibit 2.4. Swing Loan Lender’s agreement to make Swing Loans under this Agreement is cancelable at any time for any reason whatsoever and the making of Swing Loans by Swing Loan Lender from time to time shall not

create any duty or obligation, or establish any course of conduct, pursuant to which Swing Loan Lender shall thereafter be obligated to make Swing Loans in the future.

(b)Upon either (x) any request by Borrowing Agent for a Revolving Advance made pursuant to Section 2.2(a) hereof or (y) the occurrence of any deemed request by Borrowers for a Revolving Advance pursuant to the provisions of Section 2.2(a) hereof, Swing Loan Lender may elect, in its sole discretion, to have such request or deemed request treated as a request for a Swing Loan, and may advance same day funds to Borrowers as a Swing Loan; provided that notwithstanding anything to the contrary provided for herein, Swing Loan Lender may not make Swing Loan Advances if Swing Loan Lender has been notified by Agent or by Required Lenders that one or more of the applicable conditions set forth in Section 8.2 hereof have not been satisfied or the Revolving Commitments have been terminated for any reason.

(c)Upon the making of a Swing Loan (whether before or after the occurrence of a Default or an Event of Default and regardless of whether a Settlement has been requested with respect to such Swing Loan), each Revolving Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from Swing Loan Lender, without recourse or warranty, an undivided interest and participation in such Swing Loan in proportion to its Revolving Commitment Percentage. Swing Loan Lender or Agent may, at any time, require the Revolving Lenders to fund such participations by means of a Settlement as provided for in Section 2.6(d) hereof. From and after the date, if any, on which any Revolving Lender is required to fund, and funds, its participation in any Swing Loans purchased hereunder, Agent shall promptly distribute to such Revolving Lender its Revolving Commitment Percentage of all payments of principal and interest and all proceeds of Collateral received by Agent in respect of such Swing Loan; provided that no Revolving Lender shall be obligated in any event to make Revolving Advances in an amount outstanding at any time in excess of its Revolving Commitment Amount as in effect at such time minus its Participation Commitment (taking into account any reallocations under Section 2.22 hereof) of the Dollar Equivalent of the Maximum Undrawn Amount of all Letters of Credit outstanding at such time minus its Ex-Im Revolving Commitment Percentage of the Ex-Im Subfacility Outstandings Amount at such time.

2.5Disbursement of Advance Proceeds. All Advances shall be disbursed from whichever office or other place Agent may designate from time to time and, together with any and all other Obligations of Loan Parties to Agent or Lenders, shall be charged to Borrowers’ Account on Agent’s books. The proceeds of each Revolving Advance or Swing Loan requested by Borrowing Agent on behalf of Borrowers or deemed to have been requested by Borrowers under Sections 2.2(a), 2.14, or 2.22 hereof shall, (i) with respect to requested Revolving Advances, to the extent Revolving Lenders make such Revolving Advances in accordance with Sections 2.2(a), 2.14, or 2.22 hereof, and with respect to Swing Loans made upon any request or deemed request by Borrowing Agent for a Revolving Advance to the extent Swing Loan Lender makes such Swing Loan in accordance with Section 2.4(b) hereof, be made available to the Borrowers on the day so requested by way of credit to Borrowers’ operating account at Agent, or such other bank as Borrowing Agent may designate following notification to Agent, in immediately available federal funds or other immediately available funds, or (ii) with respect to Revolving Advances deemed to have been requested by Borrowers or Swing Loans made upon any deemed request for a Revolving Advance by Borrowers, be disbursed to Agent to be applied to the outstanding Obligations giving rise to such deemed request. During the Term, Borrowers may use the Revolving Advances and

Swing Loans by borrowing, prepaying and reborrowing, all in accordance with the terms and conditions hereof.

(a)Each borrowing of Revolving Advances shall be advanced according to the applicable Revolving Commitment Percentages of the respective Revolving Lenders (subject to any contrary terms of Section 2.22 hereof). The Term Loan shall be advanced on the Closing Date according to the applicable Term Loan Commitment Percentages of the respective Term Loan Lenders. Each borrowing of Swing Loans shall be advanced by the Swing Loan Lender alone.

(b)Promptly after receipt by Agent of a request or a deemed request for a Revolving Advance pursuant to Section 2.2(a) hereof and, with respect to Revolving Advances, to the extent Agent elects not to provide a Swing Loan or the making of a Swing Loan would result in the aggregate amount of all outstanding Swing Loans exceeding the maximum amount permitted in Section 2.4(a) hereof, Agent shall notify the Revolving Lenders of its receipt of such request specifying the information provided by Borrowing Agent and the apportionment among Revolving Lenders of the requested Revolving Advance as determined by Agent in accordance with the terms hereof. Each Revolving Lender shall remit the principal amount of each Revolving Advance to Agent such that Agent is able to, and Agent shall, to the extent the applicable Revolving Lenders have made funds available to it for such purpose and subject to Section 8.2 hereof, fund such Revolving Advance to Borrowers in U.S. Dollars and immediately available funds at the Payment Office prior to the close of business, on the applicable borrowing date; provided that if any applicable Revolving Lender fails to remit such funds to Agent in a timely manner, Agent may elect in its sole discretion to fund with its own funds the Revolving Advance of such Revolving Lender on such borrowing date, and such Revolving Lender shall be subject to the repayment obligation in Section 2.6(c) hereof.

(c)Unless Agent shall have been notified by telephone, confirmed in writing, by any Revolving Lender that such Revolving Lender will not make the amount which would constitute its applicable Revolving Commitment Percentage of the requested Revolving Advance available to Agent, Agent may (but shall not be obligated to) assume that such Revolving Lender has made such amount available to Agent on such date in accordance with Section 2.6(b) hereof and may, in reliance upon such assumption, make available to Borrowers a corresponding amount. In such event, if a Revolving Lender has not in fact made its applicable Revolving Commitment Percentage of the requested Revolving Advance available to Agent, then the applicable Revolving Lender and Borrowers severally agree to pay to Agent on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to Borrowers through but excluding the date of payment to Agent, at (i) in the case of a payment to be made by such Revolving Lender, the greater of (A) (x) the daily average Federal Funds Effective Rate (computed on the basis of a year of 360 days) during such period as quoted by Agent, times (y) such amount or (B) a rate determined by Agent in accordance with banking industry rules on interbank compensation, and (ii) in the case of a payment to be made by Borrowers, the Revolving Interest Rate for Revolving Advances that are Domestic Rate Loans or the Term Loan Interest Rate for the portion of the Term Loan consisting of Domestic Rate Loans, as applicable. If such Revolving Lender pays its share of the applicable Revolving Advance to Agent, then the amount so paid shall constitute such Revolving Lender’s Revolving Advance. Any

payment by Borrowers shall be without prejudice to any claim Borrowers may have against a Revolving Lender that shall have failed to make such payment to Agent. A certificate of Agent submitted to any Revolving Lender or Borrowers with respect to any amounts owing under this paragraph (c) shall be conclusive, in the absence of manifest error.

(d)Agent, on behalf of Swing Loan Lender, shall demand settlement (a “Settlement”) of all or any Swing Loans with Revolving Lenders on at least a weekly basis, or on any more frequent date that Agent elects or that Swing Loan Lender at its option exercisable for any reason whatsoever may request, by notifying Revolving Lenders of such requested Settlement by facsimile, telephonic or electronic transmission no later than 2:00 p.m. on the date of such requested Settlement (the “Settlement Date”). Subject to any contrary provisions of Section 2.22 hereof, each Revolving Lender shall transfer the amount of such Revolving Lender’s Revolving Commitment Percentage of the outstanding principal amount (plus interest accrued thereon to the extent requested by Agent) of the applicable Swing Loan with respect to which Settlement is requested by Agent, to such account of Agent as Agent may designate not later than 5:00 p.m. on such Settlement Date if requested by Agent by 2:00 p.m., otherwise not later than 5:00 p.m. on the next Business Day. Settlements may occur at any time notwithstanding that the conditions precedent to making Revolving Advances set forth in Section 8.2 hereof have not been satisfied or the Revolving Commitments shall have otherwise been terminated at such time. All amounts so transferred to Agent shall be applied against the amount of outstanding Swing Loans and, when so applied shall constitute Revolving Advances of such Revolving Lenders accruing interest as Domestic Rate Loans. If any such amount is not transferred to Agent by any Revolving Lender on such Settlement Date, Agent shall be entitled to recover such amount on demand from such Revolving Lender together with interest thereon as specified in Section 2.6(c) hereof.

(e)If any Lender or Participant (a “Benefited Lender”) shall at any time receive any payment of all or part of its Advances, or interest thereon, or receive any Collateral in respect thereof (whether voluntarily or involuntarily or by set-off) in a greater proportion than any such payment to and Collateral received by any other Lender, if any, in respect of such other Lender’s Advances, or interest thereon, and such greater proportionate payment or receipt of Collateral is not expressly permitted hereunder, such Benefited Lender shall purchase for cash from the other Lenders a participation in such portion of each such other Lender’s Advances, or shall provide such other Lender with the benefits of any such Collateral, or the proceeds thereof, as shall be necessary to cause such Benefited Lender to share the excess payment or benefits of such Collateral or proceeds ratably with each of the other Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such Benefited Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. Each Borrower consents to the foregoing and agrees, to the extent it may effectively do so under Applicable Law, that each Lender so purchasing a portion of another Lender’s Advances may exercise all rights of payment (including rights of set-off) with respect to such portion as fully as if such Lender were the direct holder of such portion, and the obligations owing to each such purchasing Lender in respect of such participation and such purchased portion of any other Lender’s Advances shall be part of the Obligations secured by the Collateral, and the obligations owing to each such purchasing Lender in respect of such participation and such purchased portion of any other Lender’s Advances shall be part of the Obligations secured by the Collateral.

2.7Maximum Advances. Notwithstanding anything to the contrary set forth in Section 2.1(a) hereof or otherwise in this Agreement, (A) the aggregate principal amount of Swing Loans and the Revolving Advances at any one time outstanding plus the Dollar Equivalent of the Maximum Undrawn Amount of all Letters of Credit outstanding at such time shall not exceed the Total Domestic Borrowing Availability at such time, and (B) the aggregate principal amount of Swing Loans and the Revolving Advances at any one time outstanding plus the Dollar Equivalent of Maximum Undrawn Amount of all Letters of Credit outstanding at such time, plus the Ex-Im Subfacility Outstandings Amount at such time shall not exceed the Total Borrowing Availability at such time. Notwithstanding anything to the contrary in any of the foregoing or otherwise herein or in the Ex-Im Subfacility Credit Agreement, at no time may (I) the Dollar Equivalent of the sum of (x) the aggregate principal amount of Swing Loans and the Revolving Advances at any one time outstanding plus the Dollar Equivalent of the Maximum Undrawn Amount of all Letters of Credit outstanding at such time, plus (y) the Ex-Im Subfacility Outstandings Amount at such time exceed (II) the Maximum Revolving Advance Amount as in effect at such time, less Reserves established hereunder as in effect at such time, less Ex-Im Reserves established under the Ex-In Subfacility Credit Agreement as in effect at such time, and no Advance shall be made hereunder (including the issuance of any Letter of Credit) at any time if, after giving effect to the making (or issuance) thereof, the foregoing provisions of this sentence would be violated.

(a)The Revolving Advances and Swing Loans shall be due and payable in full on the last day of the Term subject to earlier prepayment as herein provided. The Term Loan shall be due and payable as provided in Section 2.3(a) hereof and shall be due and payable in full on the last day of the Term, subject to mandatory prepayments as herein provided. Notwithstanding the foregoing, all Advances shall be subject to earlier repayment upon (x) acceleration upon the occurrence of an Event of Default under this Agreement or (y) termination of this Agreement. Subject to the provisions of Sections 4.8(h) and 11.5 hereof, each payment (including each prepayment) by on behalf of any Loan Party on account of the principal of and/or interest on the Advances (other than the Term Loan and the Letters of Credit) shall be applied, first to the outstanding Swing Loans, and next, to the Revolving Advances pro rata according to the applicable Revolving Commitment Percentages of the Revolving Lenders (subject to any contrary provisions of Section 2.22 hereof). Subject to the provisions of Sections 2.20 and 11.5 hereof, each payment (including each prepayment) by or on behalf of any Loan Party on account of the principal of and/or interest on the Term Loan shall be applied to the Term Loan pro rata according to the ratable interests of the Lenders therein, and, with respect to any such prepayment of principal, in the inverse order of maturities of the scheduled principal amortization with respect to the Term Loan.

(b)Each Borrower recognizes that the amounts evidenced by checks, notes, drafts or any other items of payment relating to and/or proceeds of Collateral may not be collectible by Agent on the date received by Agent. Agent shall conditionally credit Borrowers’ Account for each item of payment on the next Business Day after the Business Day on which such item of payment is received by Agent (and the Business Day on which each such item of payment is so credited shall be referred to, with respect to such item, as the “Application Date”). Agent is not, however, required to credit Borrowers’ Account for the amount of any item of payment which is unsatisfactory to Agent and Agent may charge Borrowers’ Account for the amount of any item of payment which is returned, for any reason whatsoever, to Agent unpaid. Subject to the foregoing,

Borrowers agree that for purposes of computing the interest charges under this Agreement, each item of payment received by Agent shall be deemed applied by Agent on account of the Obligations on its respective Application Date. Borrowers further agree that there is a monthly float charge payable to Agent for Agent’s sole benefit, in an amount equal to (y) the face amount of all items of payment received during the prior month (including items of payment received by Agent as a wire transfer or electronic depository check) multiplied by (z) the Revolving Interest Rate with respect to Domestic Rate Loans for one (1) Business Day. All proceeds received by Agent shall be applied to the Obligations in accordance with Section 4.8(h) hereof.

(c)All payments of principal, interest and other amounts payable hereunder, or under any of the Other Documents shall be made to Agent at the Payment Office not later than 2:00 p.m. on the due date therefor in Dollars in federal funds or other funds immediately available to Agent. Agent shall have the right to effectuate payment of any and all Obligations due and owing hereunder by charging Borrowers’ Account or by making Advances as provided in Section 2.2 hereof.

(d)Except as expressly provided herein, all payments (including prepayments) to be made by Borrowers on account of principal, interest, fees and other amounts payable hereunder shall be made without deduction, setoff or counterclaim and shall be made to Agent on behalf of Lenders to the Payment Office, in each case on or prior to 2:00 p.m., in Dollars and in immediately available funds.

2.9Repayment of Excess Advances. If at any time the aggregate balance of outstanding Revolving Advances, Swing Loans, Term Loan, and/or Advances taken as a whole exceeds the maximum amount of such type of Advances and/or Advances taken as a whole (as applicable) permitted hereunder (specifically including without limitation, if at any time (A) the aggregate principal amount of Swing Loans and the Revolving Advances at any one time outstanding plus the Dollar Equivalent of the Maximum Undrawn Amount of all Letters of Credit outstanding at such time exceeds the Total Domestic Borrowing Availability at such time, or (B) the aggregate principal amount of Swing Loans and the Revolving Advances at any one time outstanding plus the Dollar Equivalent of the Maximum Undrawn Amount of all Letters of Credit outstanding at such time, plus the Ex-Im Subfacility Outstandings Amount at such time exceeds the Total Borrowing Availability at such time), such excess Advances shall be immediately due and payable without the necessity of any demand, at the Payment Office, whether or not a Default or an Event of Default has occurred.

2.10Statement of Account. Agent shall maintain, in accordance with its customary procedures, a loan account (“Borrowers’ Account”) in the name of Borrowers in which shall be recorded the date and amount of each Advance made by Agent or Lenders and the date and amount of each payment in respect thereof; provided, however, the failure by Agent to record the date and amount of any Advance shall not adversely affect Agent or any Lender. Each month, Agent shall send to Borrowing Agent a statement showing the accounting for the Advances made, payments made or credited in respect thereof, and other transactions between Agent, Lenders and Borrowers and the other Loan Parties during such month. The monthly statements shall be deemed correct and binding upon Borrowers in the absence of manifest error and shall constitute an account stated between Lenders and Borrowers unless Agent receives a written statement of Borrowers’ specific exceptions thereto within thirty (30) days after such statement is received by Borrowing Agent.

The records of Agent with respect to Borrowers’ Account shall be conclusive evidence absent manifest error of the amounts of Advances and other charges thereto and of payments applicable thereto.

(a)Subject to the terms and conditions hereof, Issuer shall issue or cause the issuance of standby and/or trade letters of credit denominated in Dollars or an Approved LC Currency (“Letters of Credit”, and any Letter of Credit denominated in any currency other than Dollars is a “Foreign Currency Letter of Credit”) for the account of any Borrower except to the extent that the issuance thereof would then cause any of (A) the sum of (i) the outstanding Revolving Advances plus (ii) the outstanding Swing Loans, plus (iii) the Dollar Equivalent of the Maximum Undrawn Amount of all outstanding Letters of Credit, plus (iv) the Dollar Equivalent of the Maximum Undrawn Amount of the Letter of Credit to be issued to exceed Total Domestic Borrowing Availability, or (B) the sum of (i) the outstanding Revolving Advances plus (ii) the outstanding Swing Loans, plus (iii) the Dollar Equivalent of the Maximum Undrawn Amount of all outstanding Letters of Credit, plus (iv) the Ex-Im Subfacility Outstandings Amount plus (v) the Dollar Equivalent of the Maximum Undrawn Amount of the Letter of Credit to be issued to exceed Total Borrowing Availability. The Dollar Equivalent of the Maximum Undrawn Amount of all outstanding Letters of Credit shall not exceed in the aggregate at any time the Letter of Credit Sublimit. All disbursements or payments related to Letters of Credit shall be deemed to be Domestic Rate Loans consisting of Revolving Advances and shall bear interest at the Revolving Interest Rate for Domestic Rate Loans. Letters of Credit that have not been drawn upon shall not bear interest (but fees shall accrue in respect of outstanding Letters of Credit as provided in Section 3.2 hereof).

(b)Notwithstanding any provision of this Agreement, Issuer shall not be under any obligation to issue any Letter of Credit if (i) any order, judgment or decree of any Governmental Body or arbitrator shall by its terms purport to enjoin or restrain Issuer from issuing any Letter of Credit, or any Law applicable to Issuer or any request or directive (whether or not having the force of law) from any Governmental Body with jurisdiction over Issuer shall prohibit, or request that Issuer refrain from, the issuance of letters of credit generally or the Letter of Credit in particular or shall impose upon Issuer with respect to the Letter of Credit any restriction, reserve or capital requirement (for which Issuer is not otherwise compensated hereunder) not in effect on the Closing Date, or shall impose upon Issuer any unreimbursed loss, cost or expense which was not applicable on the Closing Date, and which Issuer in good faith deems material to it, or (ii) the issuance of the Letter of Credit would violate one or more policies of Issuer applicable to letters of credit generally.

(a)Borrowing Agent, on behalf of any Borrower, may request any Issuer to issue or cause the issuance of a Letter of Credit by delivering to Issuer, with a copy to Agent at the Payment Office, prior to 2:00 p.m., at least five (5) Business Days prior to the proposed date of issuance, such Issuer’s form of Letter of Credit Application (the “Letter of Credit Application”) completed to the satisfaction of Agent and Issuer; and, such other certificates, documents and other papers and information as Agent or Issuer may reasonably request. Issuer shall not issue any requested

Letter of Credit if such Issuer has received notice from Agent or any Lender that one or more of the applicable conditions set forth in Section 8.2 hereof have not been satisfied or the Revolving Commitments have been terminated for any reason.

(b)Each Letter of Credit shall, among other things, (i) provide for the payment of sight drafts, other written demands for payment, or acceptances of usance drafts when presented for honor thereunder in accordance with the terms thereof and when accompanied by the documents described therein, and (ii) have an expiry date not later than twelve (12) months after such Letter of Credit’s date of issuance and in no event later than the last day of the Term (provided that, any Issuer may, in its sole discretion, agree from time to time to issue any one and/or more Letters of Credit with a term longer than twelve (12) months but not extending beyond the last day of the Term, and further provided that, any Issuer may, in its sole discretion, agree from time to time to issue any one and/or more Letters of Credit with customary “evergreen” provisions providing that the applicable Letter of Credit will automatically renew at the end of the initial term thereof (and at the end of any subsequent renewal term) for a stated renewal term unless such Issuer shall deliver a notice of non-renewal to the beneficiary thereof by a stated deadline prior to the expiration of any such initial and/or renewal term (but in any such case, no Issuer shall allow any such Letter of Credit to be extended for a renewal term that would expire after the last day of the Term as in effect at the time of any applicable deadline under any such “evergreen” Letter of Credit for such Issue to give such a notice of non-renewal). Each standby Letter of Credit shall be subject either to the Uniform Customs and Practice for Documentary Credits as most recently published by the International Chamber of Commerce at the time a Letter of Credit is issued (the “UCP”) or the International Standby Practices (International Chamber of Commerce Publication Number 590), or any subsequent revision thereof at the time a standby Letter of Credit is issued, as determined by Issuer, and each trade Letter of Credit shall be subject to the UCP. In addition, no trade Letter of Credit may permit the presentation of an ocean bill of lading that includes a condition that the original bill of lading is not required to claim the goods shipped thereunder.

(c)Agent shall use its reasonable efforts to notify Lenders of the request by Borrowing Agent for a Letter of Credit hereunder.

(a)Borrowing Agent shall authorize and direct any Issuer to name the applicable Borrower as the “Applicant” or “Account Party” of each Letter of Credit. If Agent is not Issuer of any Letter of Credit, Borrowing Agent shall authorize and direct Issuer to deliver to Agent all agreements, documents, instruments and property received by Issuer pursuant to such Letter of Credit and to accept and rely upon Agent’s instructions and agreements with respect to all matters arising in connection with such Letter of Credit, and the application therefor.

(b)In connection with all trade Letters of Credit issued or caused to be issued by Issuer under this Agreement, each Loan Party hereby appoints Issuer, or its designee, as its attorney, with full power and authority if an Event of Default shall have occurred: (i) to sign and/or endorse such Loan Party’s name upon any warehouse or other receipts, and acceptances; (ii) to sign such Loan Party’s name on bills of lading; (iii) to clear Inventory through the United States of America Customs Department (“Customs”) in the name of such Loan Party or Issuer or Issuer’s designee, and to sign and deliver to Customs officials powers of attorney in the name of such Loan Party for

such purpose; and (iv) to complete in such Loan Party’s name or Issuer’s, or in the name of Issuer’s designee, any order, sale or transaction, obtain the necessary documents in connection therewith, and collect the proceeds thereof. Neither Agent, Issuer nor their attorneys will be liable for any acts or omissions nor for any error of judgment or mistakes of fact or law, except for Agent’s, Issuer’s or their respective attorney’s willful misconduct. This power, being coupled with an interest, is irrevocable as long as any Letters of Credit remain outstanding.

(a)Immediately upon the issuance of each Letter of Credit, each Revolving Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from Issuer a participation in each Letter of Credit and each drawing thereunder in an amount equal to such Lender’s Revolving Commitment Percentage of the Dollar Equivalent of the Maximum Undrawn Amount of such Letter of Credit (as in effect from time to time) and the amount of such drawing, respectively.

(b)In the event of any request for a drawing under a Letter of Credit by the beneficiary or transferee thereof, Issuer will promptly notify Agent and Borrowing Agent. Regardless of whether Borrowing Agent shall have received such notice, Borrowers shall reimburse (such obligation to reimburse Issuer shall sometimes be referred to as a “Reimbursement Obligation”) Issuer prior to 2:00 p.m. on each date that an amount is paid by Issuer under any Letter of Credit (each such date, a “Drawing Date”) in an amount in Dollars equal to the Dollar Equivalent of the amount so paid by Issuer (the “Dollar Equivalent Drawing Amount”). In the event Borrowers fail to reimburse Issuer for the full Dollar Equivalent Drawing Amount of any drawing under any Letter of Credit by 2:00 p.m. on the Drawing Date, Issuer will promptly notify Agent and each Revolving Lender thereof, and Borrowers shall be automatically deemed to have requested that a Revolving Advance in Dollars in the amount of the applicable Dollar Equivalent Drawing Amount maintained as a Domestic Rate Loan be made by Lenders to be disbursed on the Drawing Date under such Letter of Credit, and Revolving Lenders shall be unconditionally obligated to fund such Revolving Advance (all whether or not the conditions specified in Section 8.2 hereof are then satisfied or the Revolving Commitments have been terminated for any reason) as provided for in Section 2.14(c) hereof. Any notice given by Issuer pursuant to this Section 2.14(b) may be oral if promptly confirmed in writing; provided that the lack of such a confirmation shall not affect the conclusiveness or binding effect of such notice.

(c)Each Revolving Lender shall upon any notice pursuant to Section 2.14(b) hereof make available to Issuer through Agent at the Payment Office an amount in immediately available funds equal to its Revolving Commitment Percentage (subject to any contrary provisions of Section 2.22 hereof) of the Dollar Equivalent Drawing Amount, whereupon the participating Lenders shall (subject to Section 2.14(d) hereof) each be deemed to have made a Revolving Advance in Dollars maintained as a Domestic Rate Loan to Borrowers in that amount. If any Revolving Lender so notified fails to make available to Agent, for the benefit of Issuer, the amount of such Lender’s Revolving Commitment Percentage of such Dollar Equivalent Drawing Amount by 5:00 p.m. on the Drawing Date, then interest shall accrue on such Lender’s obligation to make such payment, from the Drawing Date to the date on which such Lender makes such payment (i) at a rate per annum equal to the Federal Funds Effective Rate during the first three (3) days following the Drawing Date and (ii) at a rate per annum equal to the rate applicable to Revolving

Advances maintained as a Domestic Rate Loan on and after the fourth day following the Drawing Date. Agent and Issuer will promptly give notice of the occurrence of the Drawing Date, but failure of Agent or Issuer to give any such notice on the Drawing Date or in sufficient time to enable any Revolving Lender to effect such payment on such date shall not relieve such Lender from its obligations under this Section 2.14(c), provided that such Lender shall not be obligated to pay interest as provided in this Section 2.14(c) until and commencing from the date of receipt of notice from Agent or Issuer of a drawing.

(d)With respect to any unreimbursed drawing that is not converted into a Revolving Advance in Dollars in the amount of the applicable Dollar Equivalent Drawing Amount maintained as a Domestic Rate Loan to Borrowers in whole or in part as contemplated by Section 2.14(b) hereof, because of Borrowers’ failure to satisfy the conditions set forth in Section 8.2 hereof (other than any notice requirements) or for any other reason, Borrowers shall be deemed to have incurred from Agent a borrowing (each a “Letter of Credit Borrowing”) in Dollars in the amount of the applicable Dollar Equivalent Drawing Amount. Such Letter of Credit Borrowing shall be due and payable in Dollars on demand (together with interest) and shall bear interest at the rate per annum applicable to a Revolving Advance in Dollars in the amount of the applicable Dollar Equivalent Drawing Amount maintained as a Domestic Rate Loan and, until paid shall be part of the Obligations secured by the Collateral. Each applicable Lender’s payment to Agent pursuant to Section 2.14(c) hereof shall be deemed to be a payment in respect of its participation in such Letter of Credit Borrowing and shall constitute a “Participation Advance” from such Lender in satisfaction of its Participation Commitment in respect of the applicable Letter of Credit under this Section 2.14.

(e)Each applicable Lender’s Participation Commitment in respect of the Letters of Credit shall continue until the last to occur of any of the following events: (x) Issuer ceases to be obligated to issue or cause to be issued Letters of Credit hereunder; (y) no Letter of Credit issued or created hereunder remains outstanding and uncancelled; and (z) all Persons (other than Borrowers) have been fully reimbursed for all payments made under or relating to Letters of Credit.

(a)Upon (and only upon) receipt by Agent for the account of Issuer of immediately available funds in Dollars from Borrowers (i) in reimbursement of any payment made by Issuer or Agent under the Letter of Credit with respect to which any Lender has made a Participation Advance to Agent, or (ii) in payment of interest on such a payment made by Issuer or Agent under such a Letter of Credit, Agent will pay to each Revolving Lender, in the same funds as those received by Agent, the amount of such Lender’s Revolving Commitment Percentage of such funds, except Agent shall retain the amount of the Revolving Commitment Percentage of such funds of any Revolving Lender that did not make a Participation Advance in respect of such payment by Agent (and, to the extent that any of the other Revolving Lenders have funded any portion such Defaulting Lender’s Participation Advance in accordance with the provisions of Section 2.22 hereof, Agent will pay over to such Non-Defaulting Lenders a pro rata portion of the funds so withheld from such Defaulting Lender).

(b)If Issuer or Agent is required at any time to return to any Loan Party, or to a trustee, receiver, liquidator, custodian, or any official in any Insolvency Proceeding, any portion of the

payments made by Borrowers or any other Loan Party to Issuer or Agent pursuant to Section 2.15(a) hereof in reimbursement of a payment made under the Letter of Credit or interest or fee thereon, each applicable Lender shall, on demand of Agent, forthwith return to Issuer or Agent the amount of its Revolving Commitment Percentage of any amounts so returned by Issuer or Agent plus interest at the Federal Funds Effective Rate.

2.16Documentation. Each Loan Party agrees to be bound by the terms of the Letter of Credit Application and by Issuer’s interpretations of any Letter of Credit issued on behalf of any Borrower and by Issuer’s written regulations and customary practices relating to letters of credit, though Issuer’s interpretations may be different from such Loan Parties’ own. In the event of a conflict between the Letter of Credit Application and this Agreement, this Agreement shall govern. It is understood and agreed that, except in the case of gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment), Issuer shall not be liable for any error, negligence and/or mistakes, whether of omission or commission, in following Borrowing Agent’s or any Loan Party’s instructions or those contained in the Letters of Credit or any modifications, amendments or supplements thereto.

2.17Determination to Honor Drawing Request. In determining whether to honor any request for drawing under any Letter of Credit by the beneficiary thereof, Issuer shall be responsible only to determine that the documents and certificates required to be delivered under such Letter of Credit have been delivered and that they comply on their face with the requirements of such Letter of Credit and that any other drawing condition appearing on the face of such Letter of Credit has been satisfied in the manner so set forth.

2.18Nature of Participation and Reimbursement Obligations. The obligation of each Revolving Lender in accordance with this Agreement to make the Revolving Advances or Participation Advances as a result of a drawing under a Letter of Credit, and the obligations of Borrowers to reimburse Issuer upon a draw under a Letter of Credit, shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Section 2.18 under all circumstances, including the following circumstances:

(i)any set-off, counterclaim, recoupment, defense or other right which such Lender or any Loan Party, as the case may be, may have against Issuer, Agent, any Loan Party or Lender, as the case may be, or any other Person for any reason whatsoever;

(ii)the failure of any Borrower or any other Person to comply, in connection with a Letter of Credit Borrowing, with the conditions set forth in this Agreement for the making of a Revolving Advance, it being acknowledged that such conditions are not required for the making of a Letter of Credit Borrowing and the obligation of Lenders to make Participation Advances under Section 2.14 hereof;

(iv)any claim of breach of warranty that might be made by any Loan Party, Agent, Issuer or any Lender against the beneficiary of a Letter of Credit, or the existence of any claim, set-off, recoupment, counterclaim, cross-claim, defense or other right which any Loan Party, Agent, Issuer or any Lender may have at any time against a beneficiary, any successor beneficiary or any transferee of any Letter of Credit or assignee

of the proceeds thereof (or any Persons for whom any such transferee or assignee may be acting), Issuer, Agent or any Lender or any other Person, whether in connection with this Agreement, the transactions contemplated herein or any unrelated transaction (including any underlying transaction between any Loan Party or any Subsidiaries of such Loan Party and the beneficiary for which any Letter of Credit was procured);

(v)the lack of power or authority of any signer of (or any defect in or forgery of any signature or endorsement on) or the form of or lack of validity, sufficiency, accuracy, enforceability or genuineness of any draft, demand, instrument, certificate or other document presented under or in connection with any Letter of Credit, or any fraud or alleged fraud in connection with any Letter of Credit, or the transport of any property or provision of services relating to a Letter of Credit, in each case even if Issuer or any of Issuer’s Affiliates has been notified thereof;

(vi)payment by Issuer under any Letter of Credit against presentation of a demand, draft or certificate or other document which is forged or does not fully comply with the terms of such Letter of Credit (provided that the foregoing shall not excuse Issuer from any obligation under the terms of any applicable Letter of Credit to require the presentation of documents that on their face appear to satisfy any applicable requirements for drawing under such Letter of Credit prior to honoring or paying any such draw);

(vii)the solvency of, or any acts or omissions by, any beneficiary of any Letter of Credit, or any other Person having a role in any transaction or obligation relating to a Letter of Credit, or the existence, nature, quality, quantity, condition, value or other characteristic of any property or services relating to a Letter of Credit;

(viii)any failure by Issuer or any of Issuer’s Affiliates to issue any Letter of Credit in the form requested by Borrowing Agent, unless Agent and Issuer have each received written notice from Borrowing Agent of such failure within three (3) Business Days after Issuer shall have provided Agent and Borrowing Agent a copy of such Letter of Credit and such error is material and no drawing has been made thereon prior to receipt of such notice;

(xi)the occurrence or continuance of an Insolvency Proceeding with respect to any Loan Party;

(xii)the fact that a Default or an Event of Default shall have occurred and be continuing;

(xiii)the fact that the Term shall have expired or this Agreement or the Commitments have been terminated;

(xiv)with respect to any Foreign Currency Letter of Credit, any fluctuation in the Exchange Rates between Dollars and the Approved LC Foreign Currency in which such Foreign Currency Letter of Credit over time and from time to time is denominated; and

(xv)any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

(a)As between Loan Parties and Issuer, Swing Loan Lender, Agent and Lenders, each Loan Party assumes all risks of the acts and omissions of, or misuse of the Letters of Credit by, the respective beneficiaries of such Letters of Credit. In furtherance and not in limitation of the foregoing, Issuer shall not be responsible for: (i) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for an issuance of any such Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged (even if Issuer or any of its Affiliates shall have been notified thereof); (ii) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any such Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; (iii) the failure of the beneficiary of any such Letter of Credit, or any other party to which such Letter of Credit may be transferred, to comply fully with any conditions required in order to draw upon such Letter of Credit or any other claim of any Loan Party against any beneficiary of such Letter of Credit, or any such transferee, or any dispute between or among any Loan Party and any beneficiary of any Letter of Credit or any such transferee; (iv) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, facsimile, telex or otherwise, whether or not they be in cipher; (v) errors in interpretation of technical terms; (vi) any loss or delay in the transmission or otherwise of any document required in order to make a drawing under any such Letter of Credit or of the proceeds thereof; (vii) the misapplication by the beneficiary of any such Letter of Credit of the proceeds of any drawing under such Letter of Credit; or (viii) any consequences arising from causes beyond the control of Issuer, including any Governmental Acts, and none of the above shall affect or impair, or prevent the vesting of, any of Issuer’s rights or powers hereunder. Nothing in the preceding sentence shall relieve Issuer from liability for Issuer’s gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment) in connection with actions or omissions described in such clauses (i) through (viii) of such sentence. In no event shall Issuer or Issuer’s Affiliates be liable to any Loan Party for any indirect, consequential, incidental, punitive, exemplary or special damages or expenses (including without limitation attorneys’ fees), or for any damages resulting from any change in the value of any property relating to a Letter of Credit.

(b)Without limiting the generality of the foregoing, Issuer and each of its Affiliates: (i) may rely on any oral or other communication believed in good faith by Issuer or such Affiliate to have been authorized or given by or on behalf of the applicant for a Letter of Credit; (ii) may honor any presentation if the documents presented appear on their face substantially to comply with the terms and conditions of the relevant Letter of Credit; (iii) may honor a previously dishonored presentation under a Letter of Credit, whether such dishonor was pursuant to a court

order, to settle or compromise any claim of wrongful dishonor, or otherwise, and shall be entitled to reimbursement to the same extent as if such presentation had initially been honored, together with any interest paid by Issuer or its Affiliates; (iv) may honor any drawing that is payable upon presentation of a statement advising negotiation or payment, upon receipt of such statement (even if such statement indicates that a draft or other document is being delivered separately), and shall not be liable for any failure of any such draft or other document to arrive, or to conform in any way with the relevant Letter of Credit; (v) may pay any paying or negotiating bank claiming that it rightfully honored under the laws or practices of the place where such bank is located; and (vi) may settle or adjust any claim or demand made on Issuer or its Affiliate in any way related to any order issued at the applicant’s request to an air carrier, a letter of guarantee or of indemnity issued to a steamship agent or carrier or any document or instrument of like import (each an “Order”) and honor any drawing in connection with any Letter of Credit that is the subject of such Order, notwithstanding that any drafts or other documents presented in connection with such Letter of Credit fail to conform in any way with such Letter of Credit.

(c)In furtherance and extension and not in limitation of the specific provisions set forth above, any action taken or omitted by Issuer under or in connection with the Letters of Credit issued by it or any documents and certificates delivered thereunder, if taken or omitted in good faith and without gross negligence (as determined by a court of competent jurisdiction in a final non-appealable judgment), shall not put Issuer under any resulting liability to any Loan Party, Agent or any Lender.

(i)Voluntary Prepayments of the Revolving Advances. Borrowers may voluntarily prepay the Swing Loans and Revolving Advances outstanding hereunder at any time in whole or in part, without any penalty or premium. Any and all voluntary prepayments of the Swing Loans and Revolving Advances under this Section 2.20(a)(i) shall be applied: first, to the repayment in full of the outstanding principal amount of any Out-of-Formula Loans and any Protective Advances made by Agent, second, to the repayment in full of the outstanding amount of any Swing Loans, third, ratably, to the repayment in full of the outstanding principal amount of all other Revolving Advances (shared among the Revolving Lenders on a pro rata basis in accordance with their respective Revolving Commitment Percentages), and fourth, if any Event of Default shall have occurred and be continuing, the cash collateralization in full of all outstanding Letters of Credit in accordance with the requirement of Section 3.2(b) hereof, all subject to Borrowers’ ability to reborrow Revolving Advances and request Letters of Credit in accordance with the terms hereof.

(ii)Voluntary Prepayments of the Term Loan. At its option and upon written notice given to Agent prior to 2:00 p.m. at least three (3) Business Days’ prior to the date of such prepayment, the Borrowers may voluntarily prepay the Term Loan in whole at any time or in part; provided that any such prepayment of Term Loan shall be in a principal amount of $1,000,000 or a whole multiple of $500,000 in excess thereof (or, if less, the entire principal amount thereof then outstanding). Each such notice shall specify the date and amount of such prepayment. Agent will promptly notify each Lender of its receipt of each such notice, and of the amount of such Lender’s

applicable pro rata share of such prepayment. Notwithstanding the foregoing or anything else in this Agreement, the Borrowers may revoke, rescind or extend a notice relative to proposed prepayment in full of the Obligations with the proceeds of third party Indebtedness or other transactions if the closing for such issuance or incurrence of Indebtedness or other transactions does not happen on the date of the proposed prepayment. Subject to the foregoing, if such notice is given by the Borrowers, the Borrowers shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein together with all accrued and unpaid interest thereon, and any voluntary prepayment of the Term Loan shall be accompanied by all accrued interest on the amount prepaid, together with any applicable fee(s) or other amounts payable under the Fee Letter in connection with or with respect to such voluntary prepayment. In the event that any prepayment of a LIBOR Rate Loan shall occur in connection with any such voluntary prepayment of the Term Loan on a date other than the last Business Day of the then current Interest Period, the Borrowers shall indemnify Agent and the Lenders therefor in accordance with Section 2.2(g) hereof. Each voluntary prepayment of the Term Loan shall be applied to the remaining scheduled payments in respect of the Term Loan as provided for under Section 2.3 hereof (including the final scheduled payment due and payable on the last day of the Term) in the inverse order of the maturity thereof, and shall be shared among the Term Loan Lenders on a pro rata basis in accordance with their respective Term Loan Commitment Percentages.

(i)When any Domestic Loan Party or Foreign Secured Loan Party makes any Disposition of any Collateral (other than (A) Export-Related Collateral or (B) any Disposition permitted by Sections 7.1, excluding Dispositions of other than Export-Related Collateral permitted by clause (a) of the definition of Permitted Dispositions, which shall be subject to the provisions of this Section 2.20(b)(i)) or any Casualty Proceeds Event occurs with respect to the Collateral (other than Export-Related Collateral) of any Domestic Loan Party or Foreign Secured Loan Party, Borrowers shall repay the Advances in an amount equal to one hundred percent (100%) of the Net Cash Proceeds of such Disposition or Casualty Proceeds Event, such repayments to be made promptly but in no event more than five (5) Business Days following receipt of such Net Cash Proceeds, and until the date of payment, such proceeds shall be held in trust for Agent; provided however that, no such mandatory prepayment shall be required under this Section 2.20(b)(i) with respect to (x) any such Disposition or Casualty Proceeds Event with respect to the Collateral (other than Export-Related Collateral) of any Domestic Loan Party to the extent that the aggregate amount of all Net Cash Proceeds of all Dispositions and Casualty Proceeds Events with respect to all Collateral (other than Export-Related Collateral) of Domestic Loan Parties in any fiscal year shall not exceed $250,000, and (y) any such Disposition or Casualty Proceeds Event with respect to the Collateral of any Foreign Secured Loan Party to the extent that the aggregate amount of all Net Cash Proceeds of all Dispositions and Casualty Proceeds Events with respect to all Collateral of Foreign Secured Loan Parties in any fiscal year shall not exceed $1,000,000, and further provided, however, with respect to Net Disposition Proceeds which would otherwise give rise to a prepayment under this Section 2.20(b)(i) (taking into account the preceding proviso), so long as no Event of Default shall have occurred and be continuing and the Borrowing Agent shall have notified Agent within five (5) Business Days following receipt of such Net Cash Proceeds of the applicable Domestic Loan Party’s or Foreign Secured Loan Party’s election to reinvest all or any portion of such Net Cash Proceeds (the “Reinvestment Proceeds”) in fixed or capital assets or

other assets useful to the business of such Loan Party that will be Collateral for the Obligations, the Borrowers shall not be required to make such prepayment out of the Reinvestment Proceeds so long as within one hundred eighty (180) days after the initial receipt of such Reinvestment Proceeds, such reinvestment shall have been consummated (and, for the avoidance of doubt, to the extent such reinvestment is not so consummated, Borrowers shall make a mandatory prepayment of the Obligations under this Section 2.20(b)(i) in the amount of such Reinvestment Proceeds that is not so reinvested on the one hundred eighty-first (181^st) day after the initial receipt of such Reinvestment Proceeds). The foregoing shall not be deemed to be implied consent to any Disposition or other transaction prohibited by the terms and conditions of this Agreement or any Other Document.

(ii)Commencing with the year ending December 31, 2019 and for each fiscal year ending thereafter, Borrowers shall prepay the outstanding amount of the Advances in an amount equal to the Excess Cash Flow Percentage of Excess Cash Flow for such fiscal year, payable within fifteen (15) days after delivery to Agent of the Annual Audited Financials for such fiscal year, but in any event not later than fifteen (15) days after the date such Annual Audited Financials are required to be delivered under Section 9.7 hereof. In the event that the Annual Audited Financials for any fiscal year are not so delivered by the date required to be delivered under Section 9.7 hereof, then a calculation based upon estimated amounts and the Quarterly Financials delivered for such year (to the extent delivered) shall be made by Agent upon which calculation and notice thereto Borrowers shall make the prepayment required by this Section 2.20(b)(ii), subject to adjustment when such required to be delivered under Section 9.7 hereof are delivered to Agent as required hereby. The calculation made by Agent shall not be deemed a waiver of any rights Agent or any Lender may have as a result of the failure by Borrowers to deliver such financial statements.

(iii)In the event of any issuance or other incurrence of Indebtedness (other than Permitted Indebtedness) by any Company, Borrowers shall, no later than three (3) Business Days after the receipt by the applicable Company of the Net Cash Proceeds thereof, repay the Advances in an amount equal to one hundred percent (100%) of such Net Cash Proceeds; provided that, notwithstanding anything to the contrary provided for in the foregoing or otherwise in this Agreement, with respect to any Contemplated Rights Offering, none of the Net Cash Proceeds of such Contemplated Rights Offering shall be subject to this Section 2.20(b)(iii).

(A)such Defaulting Lender’s Participation Commitment in the outstanding Swing Loans and of the Maximum Undrawn Amount of all outstanding Letters of Credit shall be reallocated among Non-Defaulting Lenders in proportion to the respective Revolving Commitment Percentages of such Non-Defaulting Lenders to the extent (but only to the extent) that (x) such reallocation does not cause the aggregate sum of outstanding Revolving Advances made by any such Non-Defaulting Lender plus such Lender’s reallocated Participation Commitment in the outstanding Swing Loans plus such Lender’s reallocated Participation Commitment in the aggregate Maximum Undrawn Amount of all outstanding Letters of Credit plus such Lender’s Ex-Im Revolving Commitment Percentage of the Ex-Im Subfacility Outstandings Amount (after giving effect to any reallocation under Section 2.22 of the Ex-Im

Subfacility Credit Agreement of such Lender’s Participation Commitment (as defined in the Ex-Im Subfacility Credit Agreement) of any Ex-Im Swing Loans or Ex-Im Letters of Credit) to exceed the Revolving Commitment Amount of any such Non-Defaulting Lender, and (y) no Default or Event of Default has occurred and is continuing at such time;

(B)if the reallocation described in clause (A) above cannot, or can only partially, be effected, Borrowers shall within one Business Day following notice by Agent (x) first, prepay any outstanding Swing Loans that cannot be reallocated, and (y) second, cash collateralize, for the benefit of Issuer, Borrowers’ obligations corresponding to such Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit (after giving effect to any partial reallocation pursuant to clause (A) above) in accordance with Section 3.2(b) hereof for so long as such Obligations are outstanding;

(C)if Borrowers cash collateralize any portion of such Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit pursuant to clause (B) above, Borrowers shall not be required to pay any fees to such Defaulting Lender pursuant to Section 3.2(a) hereof with respect to such Defaulting Lender’s Revolving Commitment Percentage of Maximum Undrawn Amount of all Letters of Credit during the period such Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit are cash collateralized;

(E)if all or any portion of such Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit is neither reallocated nor cash collateralized pursuant to clause (A) or (B) above, then, without prejudice to any rights or remedies of Issuer or any other Lender hereunder, all Letter of Credit Lender Fees payable under Section 3.2(a) hereof with respect to such Defaulting Lender’s Revolving Commitment Percentage of the Maximum Undrawn Amount of all Letters of Credit shall be payable to Issuer (and not to such Defaulting Lender) until (and then only to the extent that) such Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit is reallocated and/or cash collateralized; and

(F)so long as any Revolving Lender is a Defaulting Lender, Swing Loan Lender shall not be required to fund any Swing Loans and Issuer shall not be required to issue, amend or increase any Letter of Credit, unless such Issuer is satisfied that the related exposure and Defaulting Lender’s Participation Commitment in the Maximum Undrawn Amount of all Letters of Credit and all Swing Loans (after giving effect to any such issuance, amendment, increase or funding) will be fully allocated to Non-Defaulting Lenders and/or cash collateral for such Letters of Credit will be provided by Borrowers in accordance with clause (A) and (B) above, and participating interests in any newly made Swing Loan or any newly issued or increased Letter of Credit shall be allocated among Non-Defaulting Lenders in a manner consistent with Section 2.22(b)(ii)(A) above (and such Defaulting Lender shall not participate therein).

(d)Other than as expressly set forth in this Section 2.22, the rights and obligations of a Defaulting Lender (including the obligation to indemnify Agent) and the other parties hereto shall remain unchanged. Nothing in this Section 2.22 shall be deemed to release any Defaulting Lender from its obligations under this Agreement and the Other Documents, shall alter such obligations, shall operate as a waiver of any default by such Defaulting Lender hereunder, or shall prejudice any rights which any Borrower, Agent or any Lender may have against any Defaulting Lender as a result of any default by such Defaulting Lender hereunder.

(e)In the event that Agent, Borrowers, and, if such Defaulting Lenders is a Revolving Lender, Swing Loan Lender and Issuer, agree in writing that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then Agent (A) will so notify the parties hereto, and (B) if such cured Defaulting Lender is a Revolving Lender, then the Participation Commitments of all Revolving Lenders (including such cured Defaulting Lender) of the Swing Loans and Maximum Undrawn Amount of all outstanding Letters of Credit shall be reallocated to reflect the inclusion of such Lender’s Revolving Commitment, and on such date, such cured Defaulting Lender is a Revolving Lender shall purchase at par such of the Revolving Advances of the other Revolving Lenders as Agent shall determine may be necessary in order for such Lender to hold such Revolving Advances in accordance with its Revolving Commitment Percentage.

(ii)Borrowers must provide the current Lenders with written notice of any such requested increase at least thirty (30) days prior to the date requested by the Borrowers as the deadline for a response from each such current Lender regarding its participation in such requested increase, in order to allow sufficient time for the credit review and credit approval process of the Lenders, and Borrowers may not request the addition of a New Lender unless (and then only to the extent that) there is insufficient participation (after giving effect to such 30 day notice period) on behalf of the existing Lenders in the increased Revolving Commitments being requested by Borrowers;

(b)At any time following the occurrence of an Event of Default, at the option of Agent or at the direction of Required Lenders (or, in the case of any Event of Default under Section 10.7 hereof, immediately and automatically upon the occurrence of such Event of Default, without the requirement of any affirmative action by any party), or upon the last day of the Term or any other termination of this Agreement (and also, if applicable, in connection with any mandatory prepayment under Section 2.20 hereof), Borrowers will cause cash to be provided to Agent, to be held by Agent as cash collateral, in an amount equal to one hundred and three percent (103%) of the Maximum Undrawn Amount of all outstanding Letters of Credit, which may be held by Agent in one or more general ledger accounts of Agent, and each Borrower (and each Guarantor that may provide any cash collateral under its Guaranty) hereby irrevocably authorizes Agent, in its discretion, on such Loan Party’s behalf and in such Loan Party’s name, to fund any such required cash collateral to be held by Agent out of the proceeds of Receivables or other Collateral or out of any other funds of such Loan Party coming into any Lender’s possession at any time. Agent may hold such cash collateral in any one or more general ledger accounts of Agent, and Agent shall have no obligation (and Loan Parties hereby waive any claim) under Article 9 of the Uniform Commercial Code or under any other Applicable Law to pay interest on such cash collateral being held by Agent. No Loan Party may withdraw amounts credited to any such account except upon the occurrence of all of the following: (x) Payment in Full of all Obligations; (y) expiration of all Letters of Credit; and (z) termination of this Agreement. Loan Parties hereby assign, pledge and grant to Agent, for its benefit and the ratable benefit of the Secured Parties, a continuing security interest in and to and Lien on any such cash collateral and any right, title and interest of Loan Parties in any deposit account, securities account or investment account into which such cash collateral may be deposited and/or in which such cash collateral may be held by Agent from time to time to secure the Obligations, specifically including all Obligations with respect to any Letters of Credit. Loan Parties agree that upon the coming due of any Reimbursement Obligations (or any other Obligations, including Obligations for Letter of Credit Fees, with respect to the Letters of Credit), Agent may use such cash collateral to pay and satisfy such Obligations.

(b)Facility Fee. If, for any day in each calendar quarter during the Term, the daily unpaid balance of the sum of Revolving Advances outstanding on such day plus Swing Loans outstanding on such day plus the Maximum Undrawn Amount of all Letters of Credit outstanding on such day plus the Ex-Im Subfacility Outstandings Amount for such day (the “Usage Amount”) for each day of such calendar quarter does not equal the Maximum Revolving Advance Amount, then Borrowers shall pay to Agent, for the ratable benefit of the Revolving Lenders based on their Revolving Commitment Percentages, a fee at a rate equal to one-half of one percent (0.50%) per annum on the amount by which the Maximum Revolving Advance Amount on such day exceeds

such Usage Amount (the “Facility Fee”). Such Facility Fee shall be due and payable to Agent in arrears on the first Business Day of each calendar quarter with respect to each day in the previous calendar quarter and on the last day of the Term with respect to the period from the end of the previous calendar quarter through and including the last day of the Term.

(a)Fee Letter. Without duplication of any amount paid with respect to the Ex-Im Subfacility Credit Agreement, Borrowers shall pay each amount payable to the applicable Secured Party as, if, and when due under the Fee Letter.

(c)Field Examinations. Borrowers shall pay to Agent, for its sole and separate account and not the account of any Lender, promptly at the conclusion of any Field Examination conducted in accordance with the terms of Section 4.6 hereof (whether such examination is performed by Agent’s employees or by a third party retained by Agent), a collateral evaluation fee in an amount equal to (x) $1,500 per day (or such other amount customarily charged by Agent to its customers) per day for each person employed and/or retained by Agent to perform such evaluation (based on an eight (8) hour day and subject to adjustment if additional hours are worked), plus (y) a per examination field examination management fee in the amount of $2,500 (for a new facility) for each such Field Examination and $1,500 for each recurring Field Examination (or, in each case, such other amount customarily charged by Agent to its customers), plus (z) all out-of-pocket costs and disbursements incurred by Agent and its employees and agents in the performance of such Field Examination (all collectively as to any Field Examination, the “Field Examination Fees and Costs”), in full and without any deduction, off-set or counterclaim by Borrowers; provided that, notwithstanding the foregoing or anything to the contrary in this Agreement, in the absence of the occurrence and continuance of any Event of Default, Borrowers shall not be required to pay the Field Examination Fees and Costs for more than four (4) such Field Examinations in any Fiscal Year; but also provided further that the limitations set forth in the immediately foregoing proviso (1) shall not apply to any Field Examination initiated after the occurrence and during the continuance of any Event of Default (and any Field Examination conducted in Agent’s Permitted Discretion and at Borrowers’ expense after the occurrence and during the continuance of any Event of Default shall not be counted against such limitations), (2) shall not apply with respect to any Field Examination conducted by Agent with respect to any assets acquired by Loan Parties in any Acquisition (including with respect to the asset of any target acquired in any such Acquisition (and any appraisal obtained at Borrowers’ expense in connection with an Acquisition shall not be counted against such limitations), and (3) shall not limit the right of Agent in its Permitted Discretion to conduct additional Field Examinations in any Fiscal Year at its own cost and expense pursuant to Section 4.6 hereof.

(d)Appraisals. Borrowers shall pay to Agent, for its sole and separate account and not the account of any Lender, promptly at the conclusion of any appraisal of any Loan Parties’ assets obtained by Agent in accordance with the terms of Section 4.7, the out-of-pocket costs and expenses incurred by Agent in obtaining such appraisal (as to any such appraisal, the “Appraisal Costs”), in full and without deduction, off-set or counterclaim by Borrowers; provided that, notwithstanding the foregoing or anything to the contrary otherwise in this Agreement, in the

absence of the occurrence and continuance of any Event of Default, Borrowers shall not be required to pay the Appraisal Costs for more than one (1) such appraisals in any fiscal year; but also provided further that the limitations set forth in the immediately foregoing proviso (1) shall not apply after the occurrence and during the continuance of any Event of Default, (and any appraisal obtained at Borrowers’ expense after the occurrence and during the continuance of any Event of Default shall not be counted against such limitations), (2) shall not apply with respect to any appraisal conducted by Agent with respect to any assets acquired by Loan Parties in any Acquisition (including with respect to the asset of any target acquired in any such Acquisition (and any appraisal obtained at Borrowers’ expense in connection with an Acquisition shall not be counted against such limitations), and (3) shall not limit the rights of Agent in its discretion to obtain any appraisal at its own expense and cost subject to the provisions of Section 4.7 hereof.

3.5Computation of Interest and Fees. Interest and fees hereunder shall be computed on the basis of a year of 360 days and for the actual number of days elapsed. If any payment to be made hereunder becomes due and payable on a day other than a Business Day, the due date thereof shall be extended to the next succeeding Business Day and interest thereon shall be payable at the applicable Contract Rate during such extension.

3.6Maximum Charges. In no event whatsoever shall interest and other charges charged hereunder exceed the highest rate permissible under Applicable Law. In the event interest and other charges as computed hereunder would otherwise exceed the highest rate permitted under Applicable Law: (i) the interest rates hereunder will be reduced to the maximum rate permitted under Applicable Law; (ii) such excess amount shall be first applied to any unpaid principal balance owed by Borrowers; and (iii) if then remaining excess amount is greater than the previously unpaid principal balance, Lenders shall promptly refund such excess amount to Borrowers and the provisions hereof shall be deemed amended to provide for such permissible rate.

3.7Increased Costs. In the event that any Applicable Law or any Change in Law or compliance by any Lender (for purposes of this Section 3.7, the term “Lender” shall include Agent, Swing Loan Lender, any Issuer or Lender and any corporation or bank controlling Agent, Swing Loan Lender, any Lender or Issuer and the office or branch where Agent, Swing Loan Lender, any Lender or Issuer (as so defined) makes or maintains any LIBOR Rate Loans) with any request or directive (whether or not having the force of law) from any central bank or other financial, monetary or other authority, shall:

(a)subject Agent, Swing Loan Lender, any Lender or Issuer to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any participation in a Letter of Credit or any LIBOR Rate Loan, or change the basis of taxation of payments to Agent, Swing Loan Lender, such Lender or Issuer in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 3.10 hereof and the imposition of, or any change in the rate of, any Excluded Tax payable by Agent, Swing Loan Lender, such Lender or Issuer);

(b)impose, modify or deem applicable any reserve, special deposit, assessment, compulsory loan, insurance charge or similar requirement against assets held by, or deposits in or for the account of, advances or loans by, or other credit extended by, any office of Agent, Swing

Loan Lender, Issuer or any Lender, including pursuant to Regulation D of the Board of Governors of the Federal Reserve System; or

(c)impose on Agent, Swing Loan Lender, any Lender or Issuer, any other condition, loss or expense (other than Taxes) affecting this Agreement or any Other Document or any Advance made by any Lender, or any Letter of Credit or participation therein;

and the result of any of the foregoing is to increase the cost to Agent, Swing Loan Lender, any Lender or Issuer of making, converting to, continuing, renewing or maintaining its Advances hereunder by an amount that Agent, Swing Loan Lender, such Lender or Issuer deems to be material or to reduce the amount of any payment (whether of principal, interest or otherwise) in respect of any of the Advances by an amount that Agent, Swing Loan Lender or such Lender or Issuer deems to be material, then, in any case Borrowers shall promptly pay Agent, Swing Loan Lender or such Lender or Issuer, upon its demand, such additional amount as will compensate Agent, Swing Loan Lender, such Lender or Issuer for such additional cost or such reduction, as the case may be, provided that the foregoing shall not apply to increased costs which are reflected in the LIBOR Rate, as the case may be. Agent, Swing Loan Lender, such Lender or Issuer shall certify the amount of such additional cost or reduced amount to Borrowing Agent, and such certification shall be conclusive absent manifest error.

3.8.1.Interest Rate Inadequate or Unfair. In the event that Agent or any Lender shall have determined that:

(a)reasonable means do not exist for ascertaining the LIBOR Rate applicable pursuant to Section 2.2 hereof for any Interest Period;

(b)Dollar deposits in the relevant amount and for the relevant maturity are not available in the London interbank LIBOR market, with respect to an outstanding LIBOR Rate Loan, a proposed LIBOR Rate Loan, or a proposed conversion of a Domestic Rate Loan into a LIBOR Rate Loan;

(c)the making, maintenance or funding of any LIBOR Rate Loan has been made impracticable or unlawful by compliance by Agent or such Lender in good faith with any Applicable Law or any interpretation or application thereof by any Governmental Body or with any request or directive of any such Governmental Body (whether or not having the force of law), or

(d)the LIBOR Rate will not adequately and fairly reflect the cost to such Lender of the establishment or maintenance of any LIBOR Rate Loan,

then Agent shall give Borrowing Agent prompt written or telephonic notice of such determination. If such notice is given prior to a LIBOR Termination Date (as defined below) or prior to the date on which Section 3.8.2(a)(ii) hereof applies, (i) any such requested LIBOR Rate Loan shall be made as a Domestic Rate Loan, unless Borrowing Agent shall notify Agent no later than 2:00 p.m. two (2) Business Days prior to the date of such proposed borrowing, that its request for such borrowing shall be cancelled or made as an unaffected type of LIBOR Rate Loan, (ii) any Domestic

Rate Loan or LIBOR Rate Loan which was to have been converted to an affected type of LIBOR Rate Loan shall be continued as or converted into a Domestic Rate Loan, or, if Borrowing Agent shall notify Agent, no later than 2:00 p.m. two (2) Business Days prior to the proposed conversion, shall be maintained as an unaffected type of LIBOR Rate Loan, and (iii) any outstanding affected LIBOR Rate Loans shall be converted into a Domestic Rate Loan, or, if Borrowing Agent shall notify Agent, no later than 2:00 p.m. two (2) Business Days prior to the last Business Day of the then current Interest Period applicable to such affected LIBOR Rate Loan, shall be converted into an unaffected type of LIBOR Rate Loan, on the last Business Day of the then current Interest Period for such affected LIBOR Rate Loans (or sooner, if any Lender cannot continue to lawfully maintain such affected LIBOR Rate Loan). Until such notice has been withdrawn, Lenders shall have no obligation to make an affected type of LIBOR Rate Loan or maintain outstanding affected LIBOR Rate Loans and no Borrower shall have the right to convert a Domestic Rate Loan or an unaffected type of LIBOR Rate Loan into an affected type of LIBOR Rate Loan.

(a)If Agent determines (which determination shall be final and conclusive, absent manifest error) that either (i) (A) the circumstances set forth in Section 3.8.1(a) hereof have arisen and are unlikely to be temporary, or (B) the circumstances set forth in Section 3.8.1(a) hereof have not arisen but the applicable supervisor or administrator (if any) of the LIBOR Rate or a Governmental Body having jurisdiction over Agent has made a public statement identifying the specific date after which the LIBOR Rate shall no longer be used for determining interest rates for loans (either such date, a “LIBOR Termination Date”), or (ii) a rate other than the LIBOR Rate has become a widely recognized benchmark rate for newly originated loans in Dollars in the U.S. market, then Agent may (in consultation with Borrowing Agent) choose a replacement index for the LIBOR Rate and make adjustments to applicable margins and related amendments to this Agreement as referred to below such that, to the extent practicable, the all-in interest rate based on the replacement index will be substantially equivalent to the all-in LIBOR Rate-based interest rate in effect prior to its replacement.

(b)Agent and the Loan Parties shall enter into an amendment to this Agreement to reflect the replacement index, the adjusted margins and such other related amendments as may be appropriate, in the discretion of Agent, for the implementation and administration of the replacement index-based rate. Notwithstanding anything to the contrary in this Agreement or the Other Documents (including, without limitation, Section 16.2 hereof), such amendment shall become effective without any further action or consent of any other party to this Agreement at 5:00 p.m. on the tenth (10^th) Business Day after the date a draft of the amendment is provided to the Lenders, unless Agent receives, on or before such tenth (10^th) Business Day, a written notice from the Required Lenders stating that such Lenders object to such amendment.

(c)Selection of the replacement index, adjustments to the applicable margins, and amendments to this Agreement (i) will be determined with due consideration to the then-current market practices for determining and implementing a rate of interest for newly originated loans in the United States and loans converted from a LIBOR Rate-based rate to a replacement index-based rate, and (ii) may also reflect adjustments to account for (x) the effects of the transition from the LIBOR Rate to the replacement index and (y) yield- or risk-based differences between the LIBOR Rate and the replacement index.

(d)Until an amendment reflecting a new replacement index in accordance with this Section 3.8.2 hereof is effective, each advance, conversion and renewal of a LIBOR Rate Loan will continue to bear interest with reference to the LIBOR Rate; provided however, that if Agent determines (which determination shall be final and conclusive, absent manifest error) that a LIBOR Termination Date has occurred, then following the LIBOR Termination Date, all LIBOR Rate Loans shall automatically be converted to Domestic Rate Loans until such time as an amendment reflecting a replacement index and related matters as described above is implemented.

(e)Notwithstanding anything to the contrary contained herein, if at any time the replacement index is less than zero, at such times, such index shall be deemed to be zero for purposes of this Agreement.

(a)In the event that Agent, Swing Loan Lender, Issuer or any Lender shall have determined that any Applicable Law or guideline regarding capital adequacy, or any Change in Law or any change in the interpretation or administration thereof by any Governmental Body, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by Agent, Swing Loan Lender, Issuer or any Lender (for purposes of this Section 3.9, the term “Lender” shall include Agent, Swing Loan Lender, Issuer or any Lender and any corporation or bank controlling Agent, Swing Loan Lender or any Lender and the office or branch where Agent, Swing Loan Lender or any Lender (as so defined) makes or maintains any LIBOR Rate Loans) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on Agent’s, Swing Loan Lender’s, Issuer’s or any Lender’s capital as a consequence of its obligations hereunder (including the making of any Swing Loans) to a level below that which Agent, Swing Loan Lender, Issuer or such Lender could have achieved but for such adoption, change or compliance (taking into consideration Agent’s, Swing Loan Lender’s, Issuer’s and each Lender’s policies with respect to capital adequacy) by an amount deemed by Agent, Swing Loan Lender, Issuer or any Lender to be material, then, from time to time, Borrowers shall pay upon demand to Agent, Swing Loan Lender, Issuer or such Lender such additional amount or amounts as will compensate Agent, Swing Loan Lender, Issuer or such Lender for such reduction. In determining such amount or amounts, Agent, Swing Loan Lender, Issuer or such Lender may use any reasonable averaging or attribution methods. The protection of this Section 3.9 shall be available to Agent, Swing Loan Lender, Issuer and each Lender regardless of any possible contention of invalidity or inapplicability with respect to the Applicable Law, rule, regulation, guideline or condition.

(b)A certificate of Agent, Swing Loan Lender, Issuer or such Lender setting forth such amount or amounts as shall be necessary to compensate Agent, Swing Loan Lender or such Lender with respect to Section 3.9(a) hereof when delivered to Borrowing Agent shall be conclusive absent manifest error.

(a)Any and all payments by or on account of any Obligations hereunder or under any Other Document shall be made free and clear of and without reduction or withholding for any Indemnified Taxes or Other Taxes; provided that if Loan Parties shall be required by Applicable Law to deduct any Indemnified Taxes (including any Other Taxes) from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) Agent, Swing Loan Lender, Lender, Issuer or Participant, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (ii) Loan Parties shall make such deductions and (iii) Loan Parties shall timely pay the full amount deducted to the relevant Governmental Body in accordance with Applicable Law.

(b)Without limiting the provisions of Section 3.10(a) above, Loan Parties shall timely pay any Other Taxes to the relevant Governmental Body in accordance with Applicable Law.

(c)Each Loan Party shall indemnify Agent, Swing Loan Lender, each Lender, Issuer and any Participant, as soon as practicable after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by Agent, Swing Loan Lender, such Lender, Issuer, or such Participant, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto. A certificate as to the amount of such payment or liability delivered to Loan Parties by any Lender, Swing Loan Lender, Participant, or Issuer (with a copy to Agent), or by Agent on its own behalf or on behalf of Swing Loan Lender, a Lender or Issuer, shall be conclusive absent manifest error. If any Indemnified Taxes or Other Taxes were in a Loan Party’s reasonable judgment incorrectly or illegally imposed or asserted by a relevant Governmental Body, Agent, Swing Loan Lender, Lender, Issuer or Participant, as the case may be, shall not be indemnified for such Indemnified Taxes or Other Taxes by the Loan Party.

(d)As soon as practicable after any payment of Indemnified Taxes or Other Taxes by any Loan Party to a Governmental Body, Loan Parties shall deliver to Agent the original or a certified copy of a receipt issued by such Governmental Body evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to Agent.

(e)Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which any Loan Party is resident for tax purposes, or under any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any Other Document shall deliver to Loan Parties (with a copy to Agent), at the time or times prescribed by Applicable Law or reasonably requested by Loan Parties or Agent, such properly completed and executed documentation prescribed by Applicable Law as will permit such payments to be made without withholding or at a reduced rate of withholding. Notwithstanding the submission of such documentation claiming a reduced rate of or exemption from U.S. withholding tax, Agent shall be entitled to withhold United States federal income taxes at the full 30% withholding rate if in its reasonable judgment it is required to do so under the due diligence requirements imposed upon a withholding agent under §1.1441-7(b) of the United States Income Tax Regulations or other Applicable Law. Further, Agent is indemnified under §1.1461-1(e) of the United States Income Tax Regulations against any claims and demands of any Lender,

Issuer or assignee or participant of a Lender or Issuer for the amount of any tax it deducts and withholds in accordance with regulations under §1441 of the Code. In addition, any Lender, if requested by Loan Parties or Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by Loan Parties or Agent as will enable Loan Parties or Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Without limiting the generality of the foregoing, in the event that any Loan Party is resident for tax purposes in the United States of America, any Foreign Lender (or other Lender) shall deliver to Loan Parties and Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender (or other Lender) becomes a Lender under this Agreement (and from time to time thereafter upon the request of Loan Parties or Agent, but only if such Foreign Lender (or other Lender) is legally entitled to do so), whichever of the following is applicable:

(i)two (2) duly completed valid originals of IRS Form W-8BEN or W-8BEN-E claiming eligibility for benefits of an in-force income tax treaty to which the United States of America is a party,

(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 to the effect that such Foreign Lender is not (A) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of Loan Parties within the meaning of Section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code and (y) two duly completed valid originals of IRS Form W-8BEN or W-8BEN-E,

(iv)any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in United States federal withholding Tax duly completed together with such supplementary documentation as may be prescribed by Applicable Law to permit Loan Parties to determine the withholding or deduction required to be made, or

(v)to the extent that any Lender is not a Foreign Lender, such Lender shall submit to Agent two (2) originals of an IRS Form W-9 or any other form prescribed by Applicable Law demonstrating that such Lender is not a Foreign Lender.

(f)If a payment made to a Lender, Swing Loan Lender, Participant, Issuer, or Agent under this Agreement or any Other Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Person fails 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, Swing Loan Lender, Participant, Issuer, or Agent shall deliver to Agent (in the case of Swing Loan Lender, a Lender, Participant or Issuer) and Loan Parties (A) a certification signed by the chief financial officer, principal accounting officer, treasurer or controller of such Person, and (B) other documentation reasonably requested by Agent or any Loan Party sufficient for Agent and Loan Parties to comply with their obligations under FATCA and to determine that Swing Loan Lender, such Lender, Participant, Issuer, or Agent has complied with such applicable reporting requirements.

(g)If Agent, Swing Loan Lender, a Lender, a Participant or Issuer determines, in its sole discretion, that it has received a refund of any Indemnified Taxes or Other Taxes as to which it has been indemnified by Loan Parties or with respect to which Loan Parties have paid additional amounts pursuant to this Section, it shall pay to Loan Parties an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by Loan Parties under this Section with respect to the Indemnified Taxes or Other Taxes giving rise to such refund); net of all out-of-pocket expenses of Agent, Swing Loan Lender, such Lender, Participant, or Issuer, as the case may be, and without interest (other than any interest paid by the relevant Governmental Body with respect to such refund), provided that Loan Parties, upon the request of Agent, Swing Loan Lender, such Lender, Participant, or Issuer, agrees to repay the amount paid over to Loan Parties (plus any penalties, interest or other charges imposed by the relevant Governmental Body) to Agent, Swing Loan Lender, such Lender, Participant or Issuer in the event Agent, Swing Loan Lender, such Lender, Participant or Issuer is required to repay such refund to such Governmental Body. This Section shall not be construed to require Agent, Swing Loan Lender, any Lender, Participant, or Issuer to make available its tax returns (or any other information relating to its taxes that it deems confidential) to Loan Parties or any other Person. This Section shall also not be construed to require Loan Parties to make available their tax returns (or any other information relating to their Taxes that they deem confidential) to Agent, Swing Loan Lender, any Lender, Participant, or Issuer or to any other Person.

3.11Replacement of Lenders. If any Lender (an “Affected Lender”) (a) makes demand upon Borrowers for (or if Borrowers are otherwise required to pay) amounts pursuant to Section 3.7 or 3.9 hereof, (b) is unable to make or maintain LIBOR Rate Loans as a result of a condition described in Section 2.2(h) hereof, (c) is a Defaulting Lender, or (d) denies any consent requested by Agent pursuant to Section 16.2(b) hereof, Borrowers may, within ninety (90) days of receipt of such demand, notice (or the occurrence of such other event causing Borrowers to be required to pay such compensation or causing Section 2.2(h) hereof to be applicable), or such Lender becoming a Defaulting Lender or denial of a request by Agent pursuant to Section 16.2(b) hereof, as the case may be, by notice (a “Replacement Notice”) in writing to Agent and such Affected Lender (i) request the Affected Lender to cooperate with Borrowers in obtaining a replacement Lender satisfactory to Agent and Borrowers (the “Replacement Lender”); (ii) request the non-Affected Lenders to acquire and assume all of the Affected Lender’s Advances and, if and as applicable, its Revolving Commitment as provided herein, but none of such Lenders shall be under any obligation to do so; or (iii) propose a Replacement Lender subject to approval by Agent in their good faith business judgment. If any satisfactory Replacement Lender shall be obtained, and/or if any one or more of the non-Affected Lenders shall agree to acquire and assume all of the Affected Lender’s Advances and, if and as applicable, its Revolving Commitment then such Affected Lender shall assign, in accordance with Section 16.3 hereof, all of its Advances and, if and as applicable, its Revolving Commitment, and other rights and obligations under this Agreement and the Other Documents to such Replacement Lender or non-Affected Lenders, as the case may be, in exchange for payment of the principal amount so assigned and all interest and fees accrued on the amount so assigned, plus all other Obligations then due and payable to the Affected Lender including for any breakage fee pursuant to Section 2.2(g) (as though such payment constituted a prepayment) and any Prepayment Premium or Make-Whole Amount, as applicable.

4.1Security Interest in the Collateral. To secure the prompt payment and performance to Agent and each other Secured Party of the Obligations, each Domestic Loan Party hereby assigns, pledges and grants to Agent for its benefit and for the ratable benefit of each other Secured Party, a continuing security interest in and to and Lien on all of its Collateral, whether now owned or existing or hereafter created, acquired or arising and wherever located. Each Domestic Loan Party shall mark its books and records as may be necessary or appropriate to evidence, protect and perfect Agent’s security interest and shall cause its financial statements to reflect such security interest. Each Domestic Loan Party shall provide Agent with written notice of each commercial tort claim which involves or would reasonably be expected to involve claims in excess of $500,000 promptly upon any senior executive officer of any Domestic Loan Party becoming aware of the occurrence of any events giving rise to any such claims (regardless of whether legal proceedings have yet been commenced), such notice to contain a brief description of the claims, the events out of which such claims arose and the parties against which such claims may be asserted and, if applicable in any case where legal proceedings regarding such claims have been commenced, the case title together with the applicable court and docket number. Upon delivery of each such notice, such Domestic Loan Party shall be deemed to thereby grant to Agent a security interest and lien in and to such commercial tort claims described therein and all proceeds thereof. Each Domestic Loan Party shall provide Agent with written notice promptly upon becoming the beneficiary under any letter of credit or otherwise obtaining any right, title or interest in any letter of credit rights, and at Agent’s request shall take such actions as they may reasonably request for the perfection of Agent’s security interest therein.

4.2Perfection of Security Interest. Each Loan Party (excluding any Foreign Unsecured Loan Party) shall take all action that may be necessary or desirable, or that Agent may reasonably request, so as at all times to maintain the validity, perfection, enforceability and priority of Agent’s security interest in and Lien on the Collateral or to enable Agent to protect, exercise or enforce its rights hereunder and in the Collateral, including, but not limited to, (a) immediately discharging all Liens other than Permitted Encumbrances, (b) obtaining Lien Waiver Agreements, (c) delivering to Agent, endorsed or accompanied by such instruments of assignment as Agent may specify, and stamping or marking, in such manner as Agent may specify, any and all chattel paper, instruments, letters of credit and advices thereof and documents evidencing or forming a part of the Collateral, (d) entering into warehousing, lockbox, and other custodial arrangements reasonably satisfactory to Agent, and (e) executing and delivering, as applicable, financing statements, Control Agreements, instruments of pledge, mortgages, notices and assignments, in each case in form and substance reasonably satisfactory to Agent, relating to the creation, validity, perfection, maintenance or continuation of Agent’s security interest and Lien under the Uniform Commercial Code or other Applicable Law. By its signature hereto, each Domestic Loan Party hereby authorizes Agent to file, and ratifies any such filings made prior to the date hereof, against such Domestic Loan Party, one or more financing, continuation or amendment statements pursuant to the Uniform Commercial Code in form and substance satisfactory to Agent (which statements may have a description of collateral which is broader than that set forth herein, including without limitation a description of Collateral as “all assets” and/or “all personal property” of any Domestic Loan Party). All charges, expenses and fees Agent may incur in doing any of the foregoing, and any local taxes relating thereto, shall be charged to Borrowers’ Account as a Revolving Advance of a Domestic Rate Loan and added to the Obligations, or, at Agent’s option, shall be paid by Loan Parties to Agent for its benefit and for the ratable benefit of Lenders immediately upon demand, and upon such demand, may be charged to Borrowers’ Account as provided for in Section 2.23;

provided that, promptly following any such demand and/or charge (and in no event later than the next delivery of the statement of account provided for in Section 2.10 hereof), Agent shall provide Borrowers with a reasonable description of such charges, expenses and fees so demanded and/or charged.

4.3Preservation of Collateral. Following the occurrence of a Default or an Event of Default, in addition to the rights and remedies set forth in Section 11.1 hereof, Agent: (a) may at any time take such steps as Agent deems necessary to protect Agent’s interest in and to preserve the Collateral, including the hiring of security guards or the placing of other security protection measures as Agent may deem appropriate; (b) may employ and maintain at any of any Loan Party’s premises a custodian who shall have full authority to do all acts necessary to protect Agent’s interests in the Collateral; (c) may lease warehouse facilities to which Agent may move all or part of the Collateral; (d) may use any Loan Party’s owned or leased lifts, hoists, trucks and other facilities or equipment for handling or removing the Collateral; and (e) shall have, and is hereby granted, a right of ingress and egress to the places where the Collateral is located, and may proceed over and through any of Loan Parties’ owned or leased property. Each Loan Party shall cooperate fully with all of Agent’s efforts to preserve the Collateral and will take such actions to preserve the Collateral as Agent may direct. All of Agent’s expenses of preserving the Collateral, including any expenses relating to the bonding of a custodian, shall be charged to Borrowers’ Account as a Revolving Advance maintained as a Domestic Rate Loan and added to the Obligations as provided for in Section 2.23; provided that, promptly following any such demand and/or charge (and in no event later than the next delivery of the statement of account provided for in Section 2.10 hereof), Agent shall provide Borrowers with a reasonable description of such charges, expenses and fees so demanded and/or charged.

(a)With respect to the Collateral, at the time the Collateral becomes subject to Agent’s security interest: (i) each Loan Party shall be the sole owner of and fully authorized and able to sell, transfer, pledge and/or grant a first priority security interest in each and every item of its respective Collateral to Agent; and, except for Permitted Encumbrances the Collateral shall be free and clear of all Liens whatsoever; (ii) each document and agreement executed by each Loan Party or delivered to Agent or any Lender in connection with this Agreement shall be true and correct in all respects; (iii) all signatures and endorsements of each Loan Party that appear on such documents and agreements shall be genuine and each Loan Party shall have full capacity to execute same; and (iv) each Loan Party’s equipment and Inventory shall be maintained at the locations set forth on Schedule 4.4 hereto (as such Schedule may be updated from time to time in accordance with this Agreement), and shall not be removed from such locations without the prior written consent of Agent except with respect to the sale of Inventory in the Ordinary Course of Business or the disposition of equipment to the extent permitted in Section 7.1(b) hereof.

(b)(i) There is no location at which any Loan Party (excluding any Foreign Unsecured Loan Party) has any Inventory (except for Inventory in transit) or other tangible Collateral with a value equal to the Dollar Equivalent of $500,000 or greater other than those locations listed on Schedule 4.4 hereto (as such Schedule may be updated from time to time in accordance with this Agreement); (ii) Schedule 4.4 hereto (as such Schedule may be updated from time to time in accordance with this Agreement) contains a correct and complete list of the legal names and

addresses of all warehouses at which Inventory of any Loan Party (excluding any Foreign Unsecured Loan Party) with a value equal to the Dollar Equivalent of $500,000 or greater is stored; none of the receipts received by any such Loan Party from any warehouse states that the goods covered thereby are to be delivered to bearer or to the order of a named Person or to a named Person and such named Person’s assigns; (iii) Schedule 4.4 hereto (as such Schedule may be updated from time to time in accordance with this Agreement) sets forth a correct and complete list of (A) the chief executive office of each Loan Party, (B) each business location at which any unique books and records (not duplicated at the applicable corporate headquarters of such Loan Party) of any Loan Party are kept, and (C) each business location of any Loan Party (excluding any Foreign Unsecured Loan Party) or third-party warehouse/bailee/processor of any Loan Party (excluding any Foreign Unsecured Loan Party) at which tangible Collateral with a fair market value, as to each such location, in excess of $500,000 is located, and (iv) Schedule 4.4 hereto sets forth a correct and complete list as of the Closing Date of the location, by state and street address, of all Real Property owned or leased by each Loan Party, identifying which Real Properties are owned and which are leased, together with the names and addresses of any landlords or other third parties in possession, custody or control of any Collateral with a value equal to the Dollar Equivalent of $500,000 or greater.

4.5Defense of Agent’s and Lenders’ Interests. Until (a) Payment in Full of all of the Obligations and (b) the termination of the Commitments and the termination of this Agreement, Agent’s interests in the Collateral shall continue in full force and effect to the extent not otherwise provided for under Applicable Law. During such period no Loan Party shall, without Agent’s prior written consent, pledge, sell (except for sales or other dispositions otherwise permitted in Section 7.1(b) hereof), assign, transfer, create or suffer to exist a Lien upon or encumber or allow or suffer to be encumbered in any way except for Permitted Encumbrances, any part of the Collateral. Each Loan Party shall defend Agent’s interests in the Collateral against any and all Persons whatsoever. At any time after the occurrence and during the continuance of an Event of Default and following demand by Agent (at the direction of itself) for payment of all Obligations, Agent shall have the right, to the extent permitted by Applicable Law, to take possession of the indicia of the Collateral and the Collateral in whatever physical form contained, including: labels, stationery, documents, instruments and advertising materials. If Agent exercises this right to take possession of the Collateral, each Loan Party shall, upon demand, assemble it in the best manner possible and make it available to Agent at a place reasonably convenient to Agent. In addition, with respect to all Collateral, Agent and Lenders shall be entitled to all of the rights and remedies set forth herein and further provided by the Uniform Commercial Code or other Applicable Law. Each Loan Party shall, and Agent may, instruct all suppliers, carriers, forwarders, warehousemen or others receiving or holding cash, checks, Inventory, documents or instruments in which Agent holds a security interest to deliver same to Agent and/or subject to Agent’s order and if they shall come into any Loan Party’s possession, they, and each of them, shall be held by such Loan Party in trust as Agent’s trustee, and such Loan Party will immediately deliver them to Agent in their original form together with any necessary endorsement.

4.6Inspection of Premises. At all reasonable times and from time to time as often as Agent shall elect in its sole discretion, in each case following commercially reasonable advance notice from Agent to Borrowing Agent (provided that no such advance notice shall be required at any time when any Event of Default shall have occurred and be continuing or at any time when Agent reasonably suspects in its Permitted Discretion that there has been any intentional fraud,

willful misconduct or gross negligence in the preparation of any Borrowing Base Certificate delivered to Agent under Section 9.2 hereof), Agent and each Lender shall have full access to and the right to audit, check, inspect and make abstracts and copies from each Loan Party’s books, records, audits, correspondence and all other papers relating to the Collateral and the operation of each Loan Party’s business. Agent, any Lender and their agents may enter upon any premises of any Loan Party at any time during business hours and at any other reasonable time, and from time to time as often as Agent shall elect, for the purpose of inspecting the Collateral and any and all records pertaining thereto and the operation of such Loan Party’s business. Nothing in this Section 4.6 shall contradict any of the provisions of Section 3.4(c) or the limitations on Borrowers’ liability for Field Examination Fees and Costs set forth therein.

4.7Appraisals. Agent may, in its sole discretion, exercised in a commercially reasonable manner, at any time after the Closing Date and from time to time, engage the services of an independent appraisal firm or firms of reputable standing, satisfactory to Agent, for the purpose of appraising then current values of Loan Parties’ assets. Unless an Event of Default shall have occurred and be continuing at such time, Agent shall consult with Loan Parties as to the identity of any such firm. In the event the value of Loan Parties’ assets included in the Formula Amount as so determined pursuant to such appraisal is less than anticipated by Agent such that the Revolving Advances are in excess of such Advances permitted hereunder, then, promptly upon Agent’s demand for same, Borrowers shall make mandatory prepayments of the then outstanding Revolving Advances so as to eliminate the excess Advances. Nothing in this Section 4.7 shall contradict any of the provisions of Section 3.4(d) or the limitations on Borrowers’ liability for Appraisal Costs set forth therein.

(a)Each of the Receivables shall be a bona fide and valid account representing a bona fide indebtedness incurred by the Customer therein named, for a fixed sum as set forth in the invoice relating thereto (provided that immaterial or unintentional invoice errors shall not be deemed to be a breach hereof, and further provided that customary discount provisions offered by Loan Parties to their Customers in the Ordinary Course of Business consistent with past practices shall not be deemed to be a breach hereof so long as the amount/terms of such discount(s) are clearly set forth on the invoice and the amount of such Receivable as reported on any Borrowing Base Certificate shall reflect the lowest potential amount thereof assuming application of all such discount(s) available with respect to such Receivable) with respect to an absolute sale or lease and delivery of goods upon stated terms of a Loan Party, or work, labor or services theretofore rendered by a Loan Party as of the date each Receivable is created. Same shall be due and owing in accordance with the applicable Loan Party’s standard terms of sale without dispute, setoff or counterclaim except as may be stated on the accounts receivable schedules delivered by Loan Parties to Agent.

(b)Each Customer, to each Loan Party’s actual knowledge, as of the date each Receivable is created, is and will be solvent and able to pay all Receivables on which the Customer is obligated in full when due. With respect to such Customers of any Loan Party who are not solvent, such Loan Party has set up on its books and in its financial records bad debt reserves adequate to cover such Receivables.

(c)Each Loan Party’s chief executive office is located as set forth on Schedule 4.4 hereto. Until written notice is given to Agent by Borrowing Agent of any other office at which any Loan Party keeps its records pertaining to Receivables, all such records shall be kept at such executive office.

(d)Domestic Loan Parties shall instruct their Customers to deliver all remittances upon Receivables (whether paid by check or by wire transfer of funds) to such Blocked Account(s) and/or Depository Accounts (and any associated lockboxes) as Agent shall designate from time to time as contemplated by Section 4.8(h) hereof or as otherwise agreed to from time to time by Agent. Notwithstanding the foregoing, to the extent any Domestic Loan Party directly receives any remittances upon Receivables, such Domestic Loan Party shall, at such Domestic Loan Party’s sole cost and expense, but on Agent’s behalf and for Agent’s account, collect as Agent’s property and in trust for Agent all amounts received on Receivables, and shall not commingle such collections with any Domestic Loan Party’s funds or use the same except to pay Obligations, and shall as soon as possible and in any event no later than one (1) Business Day after the receipt thereof (i) in the case of remittances paid by check, deposit all such remittances in their original form (after supplying any necessary endorsements) and (ii) in the case of remittances paid by wire transfer of funds, transfer all such remittances, in each case, into such Blocked Accounts(s) and/or Depository Account(s). Each Domestic Loan Party shall deposit in the Blocked Account and/or Depository Account or, upon request by Agent, deliver to Agent, in original form and on the date of receipt thereof, all checks, drafts, notes, money orders, acceptances, cash and other evidences of Indebtedness.

(e)At any time following the occurrence and during the continuance of an Event of Default, Agent shall have the right to send notice of the assignment of, and Agent’s security interest in and Lien on, the Receivables to any and all Customers or any third party holding or otherwise concerned with any of the Collateral. Thereafter, Agent shall have the sole right to collect the Receivables, take possession of the Collateral, or both. Agent’s actual collection expenses, including, but not limited to, stationery and postage, telephone and facsimile, secretarial and clerical expenses and the salaries of any collection personnel used for collection, may be charged to Borrowers’ Account and added to the Obligations.

(f)Agent shall have the right to receive, endorse, assign and/or deliver in the name of Agent or any Loan Party any and all checks, drafts and other instruments for the payment of money relating to the Receivables, and each Loan Party hereby waives notice of presentment, protest and non-payment of any instrument so endorsed. Each Loan Party hereby constitutes Agent or Agent’s designee as such Loan Party’s attorney with power (i) at any time: (A) to endorse such Loan Party’s name upon any acceptances, checks, drafts, money orders or other evidences of payment or Collateral received by the Agent; (B) to sign such Loan Party’s name on any drafts against Customers, assignments and verifications of Receivables; (C) to send verifications of Receivables to any Customer; and (D) to sign such Loan Party’s name on all agreements, documents or instruments deemed necessary or appropriate by Agent to preserve, protect, or perfect Agent’s interest in the Collateral and to file same; and (ii) at any time following the occurrence of an Event of Default: (A) to demand payment of the Receivables; (B) to enforce payment of the Receivables by legal proceedings or otherwise; (C) to exercise all of such Loan Party’s rights and remedies with respect to the collection of the Receivables and any other Collateral; (D) to sue upon or otherwise collect, extend the time of payment of, settle, adjust, compromise, extend or renew the

Receivables; (E) to settle, adjust or compromise any legal proceedings brought to collect Receivables; (F) to prepare, file and sign such Loan Party’s name on a proof of claim in bankruptcy or similar document against any Customer; (G) to prepare, file and sign such Loan Party’s name on any notice of Lien, assignment or satisfaction of Lien or similar document in connection with the Receivables; (H) to accept the return of goods represented by any of the Receivables; (I) to change the address for delivery of mail addressed to any Loan Party to such address as Agent may designate; (J) as part of the services offered under to receive, open and dispose of all mail addressed to any Loan Party at any post office box/lockbox maintained by Agent for Loan Parties or at any other business premises of Agent, (J) to sign such Loan Party’s name on any invoice or bill of lading relating to any of the Receivables, and (K) to do all other acts and things necessary to carry out this Agreement. All acts of such attorney or designee are hereby ratified and approved, and such attorney or designee shall not be liable for any acts of omission or commission nor for any error of judgment or mistake of fact or of law, unless done maliciously, with willful misconduct, or with gross (not mere) negligence (as determined by a court of competent jurisdiction in a final non-appealable judgment); this power being coupled with an interest is irrevocable while any of the Obligations remain unpaid.

(g)Neither Agent nor any Lender shall, under any circumstances or in any event whatsoever, have any liability for any error or omission or delay of any kind occurring in the settlement, collection or payment of any of the Receivables or any instrument received in payment thereof, or for any damage resulting therefrom.

(h)Subject to the provisions of Section 8.3(b), all proceeds of Collateral shall be deposited by Domestic Loan Parties into either (i) a lockbox account, dominion account or such other “blocked account” (each a “Blocked Account” and collectively, the “Blocked Accounts”) established at a bank or banks as are acceptable to Agent (each such bank, a “Blocked Account Bank” and collectively, the “Blocked Account Banks”) pursuant to an arrangement with such Blocked Account Bank as may be acceptable to Agent or (ii) a lockbox account, dominion account or other “blocked account” depository accounts (“Depository Accounts”) established at Agent for the deposit of such proceeds. Each applicable Domestic Loan Party, Agent and each Blocked Account Bank shall enter into a Control Agreement in form and substance satisfactory to Agent that is sufficient to give Agent “control” (for purposes of Articles 8 and 9 of the Uniform Commercial Code) over such Blocked Accounts and which directs such Blocked Account Bank to transfer such funds so deposited on a daily basis (or at such other times acceptable to Agent) to Agent, either to any account maintained by Agent at such Blocked Account Bank or by wire transfer to appropriate account(s) maintained with Agent by the Domestic Loan Parties as Agent may elect. All funds deposited in such Blocked Accounts or Depository Accounts shall immediately become subject to the security interest of Agent for its own benefit and the ratable benefit of the Secured Parties, and Borrowing Agent shall obtain the agreement by such Blocked Account Bank to waive any offset rights against the funds so deposited. Neither Agent nor any Lender assumes any responsibility for such blocked account arrangement, including any claim of accord and satisfaction or release with respect to deposits accepted by any Blocked Account Bank thereunder. Subject to the provisions of Section 11.5 hereof, Agent shall apply all funds received by it from the Blocked Accounts and/or Depository Accounts to the satisfaction of the Obligations (including the cash collateralization of the Letters of Credit in accordance with Section 3.2(b) hereof) in such order as Agent shall determine in its sole discretion, provided that, in the absence of any Event of Default, Agent shall apply all such funds representing collection of Receivables

first to the prepayment of the principal amount of any Out-of-Formula Loans and Protective Advances funded by Agent and not funded by the Revolving Lenders, if any, second, the Swing Loans, if any, and third, then to the Revolving Advances.

(i)No Loan Party will, without Agent’s consent, compromise or adjust any Receivables (or extend the time for payment thereof) or accept any returns of merchandise or grant any additional discounts, allowances or credits thereon except for those compromises, adjustments, returns, discounts, credits and allowances as have been heretofore customary in the Ordinary Course of Business of such Loan Party.

(j)All deposit accounts (including all Blocked Accounts and Depository Accounts), securities accounts and investment accounts of each Loan Party as of the Closing Date are set forth on Schedule 4.8(j). No Borrower shall open any new deposit account, securities account or investment account (other than an Excluded Account) unless (i) Borrowers shall have given at least ten (10) days prior written notice to Agent and (ii) if such account is to be maintained with a bank, depository institution or securities intermediary that is not the Agent, such bank, depository institution or securities intermediary, each applicable Borrower and Agent shall first have entered into an account control agreement in form and substance reasonably satisfactory to Agent sufficient to give Agent “control” (for purposes of Articles 8 and 9 of the Uniform Commercial Code) over such account (and, if such account is a Blocked Account, such account control agreement shall also comply with the requirements of Section 4.8(h)).

4.9Inventory. To the extent Inventory held for sale or lease has been produced by any Domestic Loan Party, it has been and will be produced by such Domestic Loan Party in accordance with the Federal Fair Labor Standards Act of 1938, as amended, modified or supplemented and all rules, regulations and orders thereunder.

4.10Maintenance of Equipment. Except for Equipment Disposed of in accordance with the terms hereof, equipment of Loan Parties shall be maintained in good operating condition and repair (reasonable wear and tear excepted) and all necessary replacements of and repairs thereto shall be made so that the value and operating efficiency of the equipment shall be maintained and preserved. No Loan Party shall use or operate its equipment in violation of any law, statute, ordinance, code, rule or regulation.

4.11Exculpation of Liability. Nothing set forth herein shall be construed to constitute Agent or any Lender as any Loan Party’s agent for any purpose whatsoever, nor shall Agent or any Lender be responsible or liable for any shortage, discrepancy, damage, loss or destruction of any part of the Collateral wherever the same may be located and regardless of the cause thereof. Neither Agent nor any Lender, whether by anything herein or in any assignment or otherwise, assume any of any Loan Party’s obligations under any contract or agreement assigned to Agent or such Lender, and neither Agent nor any Lender shall be responsible in any way for the performance by any Loan Party of any of the terms and conditions thereof.

4.12Financing Statements. Except the financing statements filed by Agent, financing statements described on Schedule 7.2 hereto and financing statements filed in connection with Permitted Encumbrances, no financing statement covering any of the Collateral or any proceeds thereof is or will be on file in any public office.

4.13Investment Property Collateral. Except as set forth in Article XI and, with respect to Subsidiary Stock, Section 4.14(h) hereof, (i) the Loan Parties will have the right to exercise all voting rights with respect to the Investment Property and (ii) the Loan Parties will have the right to receive all cash dividends and distributions, interest and premiums declared and paid on the Investment Property to the extent otherwise permitted under this Agreement. In the event any additional Equity Interests (other than Excluded Property) are issued to or acquired by any Loan Party, whether as a result of any new purchase by or transfer or assignment to such Loan Party, as a result of a stock dividend or distribution or in lieu of interest on any of the Investment Property, as a result of any split of any of the Investment Property, by reclassification, or otherwise, any certificates evidencing any such additional Equity Interests will be delivered to Agent within ten (10) Business Days and such shares will be subject to this Agreement and a part of the Investment Property to the same extent as the original Investment Property of such Loan Party on the Closing Date.

4.14Provisions Regarding Pledged Equity Interests. Without limiting the generality of Sections 4.1 or 4.13 hereof or of any Pledge Agreement that may from time to time be in effect, and as a supplement to and expansion of (and without any intention to limit or contradict) the other provisions of this Article IV and/or any provisions of any such Pledge Agreement:

(a)Each Domestic Loan Party, for the purpose of granting a continuing lien and security interest to secure the Obligations for the benefit of Agent and each other Secured Party, does hereby collaterally assign to Agent (for the benefit of Agent and each other Secured Party), and pledge to Agent (for the benefit of Agent and each other Secured Party), and grant such a continuing lien and security interest to Agent (for the benefit of Agent and each other Secured Party) in, all of such Domestic Loan Party’s right, title and interest in and to all of the following property, together with any additions, exchanges, replacements and substitutions therefor, dividends and distributions with respect thereto, and the proceeds thereof (collectively, as to all Domestic Loan Parties, the “Pledged Equity Interest Collateral”; provided that, notwithstanding anything to the contrary provided in this Section 4.14, the Pledged Equity Interest Collateral shall not at any time include any Excluded Property):

(i)all Equity Interests of any Person of any kind or nature held by such Domestic Loan Party consisting of Subsidiary Stock, whether now owned or hereafter acquired by such Domestic Loan Party or in which such Domestic Loan Party now or hereafter has any rights, options or warrants, including without limitation: (1) all of the capital stock, capital shares and other Equity Interests in those Subsidiaries consisting of corporations, companies and other business entities (other than the business entities of the types listed in the following clauses (2) and (3)), including such corporations, companies and entities listed on Schedule 4.14 hereto (as such Schedule may be amended and/or updated from time to time in accordance herewith), (2) all of the partnership interests and other Equity Interests in those Subsidiaries consisting of limited partnerships and general partnerships, including such partnerships listed on Schedule 4.14 hereto (as such Schedule may be amended and/or updated from time to time in accordance herewith), and (3) all of the membership/limited liability company interests and other Equity Interests in those Subsidiaries consisting of limited liability companies, including such limited liability companies listed on Schedule 4.14 hereto (as such Schedule may be amended and/or updated from time to time in accordance herewith), in each case (1) through (3) together

with all certificates representing such Equity Interests and all rights (but none of the obligations) under or arising out of the applicable Organizational Documents of such Subsidiaries, and specifically including without limitation, with respect to each such partnership Subsidiary, all rights and remedies of such Domestic Loan Party as a general partner or limited partner with respect to the respective partnership interests and other Equity Interests of such Domestic Loan Party in each such partnership Subsidiary under the respective Organizational Documents of such partnership and under the partnership laws of the state in which each such partnership is organized, and, with respect to each such limited liability company Subsidiary, all rights and remedies of the such Domestic Loan Party as a member or manager or managing member with respect to the respective membership interests and other Equity Interests of such Domestic Loan Party in each such limited liability company Subsidiary under the respective Organizational Documents of such limited liability company and under the limited liability company laws of the state in which each such limited liability company is organized); and

(ii)all Related Equity Interest Rights related to any such Equity Interests described in the foregoing clause (i).

(b)The pledge and security interest described in this Section 4.14 shall continue in effect to secure all Obligations under this Agreement and the Other Documents from time to time incurred or arising (a) for so long as this Agreement is in effect and (b) until the Commitments have terminated and the Obligations are Paid in Full.

(c)Pledge Representations and Warranties: Each Domestic Loan Party hereby represents and warrants as follows:

(i)Such Domestic Loan Party has not sold, assigned, transferred, pledged or granted any option or security interest in or otherwise hypothecated the Pledged Equity Interest Collateral in any manner whatsoever, and the Pledged Equity Interest Collateral is pledged herewith free and clear of any and all Liens, encumbrances, claims, pledges, restrictions, legends, options and other claims and charges, other than Permitted Encumbrances of the type described in clauses (a), (b) and (e) of the definition thereof.

(ii)The execution, delivery and performance of this Agreement and the pledge of the Pledged Equity Interest Collateral referred to herein, and all other terms and provisions hereof (specifically including Section 4.14(h) hereof and the powers and proxies granted to Agent thereunder) are not in violation of and shall not create any default under any Organizational Documents of any Pledged Issuer.

(iii)There are no restrictions upon the pledge or transfer of, nor on the voting rights associated with, or the transfer of, any of the Pledged Equity Interest Collateral, except as provided by applicable federal and state laws and the terms of the Organizational Documents of the applicable Pledged Issuer and/or as stated on the face of any applicable certificates evidencing any such Pledged Equity Interest Collateral.

(iv)The Pledged Equity Interest Collateral has been validly authorized and issued by each Pledged Issuer thereof and, if applicable, such Pledged Equity Interest Collateral is fully paid for and non-assessable.

(v)Subject to Section 8.3(g), each Domestic Loan Party has delivered to Agent all certificates representing or evidencing the Pledged Equity Interest Collateral, if any, accompanied by duly executed instruments of transfer or assignments in blank, to be held by Agent.

(d)Each Domestic Loan Party, in its capacity as a pledgor of its Pledged Equity Interest Collateral under this Section 4.14, hereby irrevocably instructs each of its direct Subsidiaries, in such direct Subsidiary’s present and/or future capacity (if, as, and when applicable) as a Pledged Issuer that has issued or at any time and/or from time to time hereafter may issue any Pledged Equity Interest Collateral now or hereafter held by such pledging Domestic Loan Party, to comply with any instructions originated by Agent with respect to the interests of such pledging Domestic Loan Party in any such Pledged Equity Interest Collateral now or hereafter issued by such Pledged Issuer that is now or at any time and/or from time to time hereafter held by such pledging Domestic Loan Party without further consent of such pledging Domestic Loan Party and each such pledging Domestic Loan Party agrees that each such Pledged Issuer shall be fully protected in so complying. Each Domestic Loan Party that is a direct Subsidiary of another Domestic Loan Party, in present and/or future capacity (if, as, and when applicable) as a Pledged Issuer that has issued or at any time and/or from time to time hereafter may issue any Pledged Equity Interest Collateral to any one or more other Domestic Loan Parties, hereby irrevocably agrees to comply with any such instructions originated by Agent with respect to any interests of any other Domestic Loan Party in any such Pledged Equity Interest Collateral now or hereafter issued by such Domestic Loan Party as such a Pledged Issuer that is now or at any time and/or from time to time hereafter held by any such pledging Domestic Loan Party without further consent of such pledging Domestic Loan Party. However, Agent agrees it shall not issue any such instructions with respect to the Pledged Collateral held by any Domestic Loan Party in any Pledged Issuer unless an Event of Default shall have occurred and be continuing. Each Domestic Loan Party acknowledges and agrees that Agent shall be authorized at any time to provide a copy of this Agreement to any Pledged Issuer as evidence that such Domestic Loan Party has given the foregoing instructions.

(e)In addition to all other rights granted to Agent in this Agreement or any Other Document, under the Uniform Commercial Code or otherwise available at law or in equity, Agent shall have the following rights, each of which may be exercised at Agent’s Permitted Discretion (but without any obligation to do so), at any time following the occurrence and during the continuance of an Event of Default hereunder, without further consent of any Domestic Loan Party: (i) transfer the whole or any part of the Pledged Equity Interest Collateral into the name of Agent or its nominee or to conduct a sale of the Pledged Equity Interest Collateral pursuant to the Uniform Commercial Code or pursuant to any other applicable law; (ii) vote the Pledged Equity Interest Collateral in whole or in part as more fully provided for in Section 4.14(h) hereof; (iii) notify the persons obligated on any of the Pledged Equity Interest Collateral to make payment to Agent of any amounts due or to become due thereon; and (iv) release, surrender or exchange any of the Pledged Equity Interest Collateral at any time, or to compromise any dispute with respect to the same. Agent may proceed against the Pledged Equity Interest Collateral, or any other Collateral securing the Obligations, in any order, and against any Domestic Loan Party pledging any of the Pledged Equity Interest Collateral and any other obligor (including without limitation, any one or more other Domestic Loan Parties), jointly and/or severally, in any order to satisfy the Obligations. Each Domestic Loan Party waives and releases any right to require Agent to first collect any of the Obligations secured by the Pledged Equity Interest Collateral from any other

Collateral of such Domestic Loan Party or any other party (including without limitation, any one or more other Domestic Loan Parties) securing the Obligations under any theory of marshalling of assets, or otherwise. Any and all dividends, distributions, interest declared, distributed or paid and any proceeds of the Pledged Equity Interest Collateral which are received by any Domestic Loan Party following the occurrence and continuance of an Event of Default under this Agreement shall be received in trust for the benefit of Agent and the Secured Parties; segregated from the other property and funds of such Domestic Loan Party; and forthwith upon demand delivered to Agent as Pledged Equity Interest Collateral in the same form as received (with any necessary documents, endorsements or assignments in blank with guaranteed signatures). All rights and remedies of Agent are cumulative, not alternative. For so long as this Agreement is in effect and until the Commitments have been terminated and the Obligations have been Paid in Full, each Domestic Loan Party hereby irrevocably appoints Agent, or Agent’s nominee or any other person whom Agent may designate, as such Domestic Loan Party’s attorney‑in‑fact, subject to the terms of this Section 4.14, following the occurrence and during the continuance of an Event of Default, with the power, at Agent’s option, (i) to effectuate the transfer of any of the Pledged Equity Interest Collateral on the books of each Pledged Issuer thereof to the name of Agent or to the name of Agent’s nominee, designee or transferee; (ii) to endorse and collect checks payable to such Domestic Loan Party representing distributions or other payments on any of the Pledged Equity Interest Collateral; and (iii) to carry out the terms and provisions of this Section 4.14. Each Domestic Loan Party acknowledges and agrees that Agent shall be authorized at any time to provide a copy of this Agreement to any Pledged Issuer as evidence that Agent has been given the foregoing power of attorney.

(f)Each Domestic Loan Party recognizes that Agent may be unable to effect, or may effect only after such delay which would adversely affect the value that might be realized from the Pledged Equity Interest Collateral, a public sale of all or part of the Pledged Equity Interest Collateral by reason of certain prohibitions contained in the Securities Act or other applicable securities legislation in any other applicable jurisdiction and may be compelled to resort to one or more private sales to a restricted group of purchasers who will be obliged to agree, among other things, to acquire such securities for their own account, for investment and not with a view to the distribution or resale thereof. Each Domestic Loan Party agrees that any such private sale may be at prices and on terms less favorable to Agent or the seller than if sold at public sales, and therefore recognizes and confirms that such private sales shall not be deemed to have been made in a commercially unreasonable manner solely because they were made privately. Each Domestic Loan Party agrees that Agent has no obligation to delay the sale of any such securities for the period of time necessary to permit any Pledged Issuer of such securities to register such securities for public sale under the Securities Act or other applicable securities legislation in any other applicable jurisdiction.

(g)In the event that (x) any Domestic Loan Party shall acquire any Equity Interests of any kind or nature in any new direct Subsidiary formed or acquired by such Domestic Loan Party after the Closing Date), or (y) any stock dividend, reclassification, readjustment or other change is made or declared in the capital structure of any direct Subsidiary or any Domestic Loan Party acquires or in any other manner receives additional shares of stock, membership/limited liability company interests, partnership interests or other Equity Interests in any Subsidiary, or any option included within the Pledged Equity Interest Collateral with respect to the stock, membership/limited liability company interests, partnership interests or other Equity Interests of

any direct Subsidiary is exercised, then any and all such new Equity Interests (together with all Related Equity Interest Rights associated therewith) so acquired, other than any Excluded Property, and any and all such new, substituted or additional Equity Interests (together with all Related Equity Interest Rights associated therewith) issued by reason of any such change or exercise to such Domestic Loan Party, other than any Excluded Property, shall immediately and automatically become subject to this Agreement specifically including this Section 4.14 and the pledge and grant of a security interest created by each Domestic Loan Party hereunder and each Domestic Loan Party hereby grants a security interest in any such future Equity Interests of any Subsidiary (together with all Related Equity Rights associated therewith) other than any Excluded Property, to Agent for the benefit of Secured Parties to secure the Obligations. Any and all certificates issued to such Domestic Loan Party with respect to any such new, substituted or additional Equity Interests, accompanied by duly executed instruments of transfer or assignments in blank, shall be delivered to and held by Agent in the same manner as the Pledged Equity Interest Collateral originally pledged hereunder. Promptly upon the acquisition by any Domestic Loan Party of any such new, substituted or additional Equity Interests, Domestic Loan Parties shall deliver written notice of such new, substituted or additional Equity Interests to Agent, which such written notice shall include an updated and amended Schedule 4.14 to this Agreement, which shall upon delivery be deemed to have amended and restated the previously effective version of such Schedule 4.14.

(h)Until the earlier of (x) the time after the occurrence and during the continuance of any Event of Default hereunder that Agent shall give notice in writing to any Domestic Loan Party (which such notice shall be automatically effective immediately upon such Domestic Loan Party’s receipt thereof) of the exercise of Agent’s rights under this Section 4.14(h), or (y) the commencement of any proceeding of the type described in clause (x) or clause (y) of Section 10.7 hereof with respect to any Domestic Loan Party (in which case no notice or other affirmative action shall be required by Agent, unless Agent shall affirmatively elect at such time to forego the effectiveness of this clause (y)) (a “Triggering Equity Event”), each Domestic Loan Party shall retain the sole right to vote the Pledged Equity Interest Collateral belonging to it and to exercise all Related Equity Interests Rights with respect to the Pledged Equity Interest Collateral belonging to it for all purposes not in violation of the terms hereof. Upon any such Triggering Equity Event as to any Domestic Loan Party, such Domestic Loan Party shall have no further rights to, and shall not, exercise any such Related Equity Interest Rights with respect to the Pledged Equity Interest Collateral belonging to it, and all such Related Equity Interest Rights with respect to the Pledged Equity Interest Collateral belonging to it shall be thereafter exercisable only by Agent (regardless of whether Agent shall have taken title to such Pledged Equity Interest Collateral and/or otherwise exercised any of its other rights and remedies with respect to such Pledged Equity Interest Collateral and even prior to any such exercise). Without limiting the generality of the foregoing, with respect to any Pledged Issuer that is a limited liability company or partnership, the Related Equity Interest Rights which Agent may exercise upon exercise of its rights under this Section 4.14(h) shall include (i) the right to replace any “managing member” or “manager” and/or any “general partner”, as applicable, of any such limited liability company or partnership Pledged Issuer and/or to replace any one or more of the members of any board of members/managers/partners/directors (or similar board) that may at any time have any rights to manage and direct the business and affairs of the applicable Pledged Issuer under its Organizational Documents as in effect from time to time (including in any such case under this clause (i), the right to replace the pledging Domestic Loan Party in any such capacity, and each Domestic Loan Party

Domestic Loan Parties hereby further acknowledge and agree that, with respect to any Subsidiary whose Equity Interests are owned only by one or more Domestic Loan Parties, if and to the extent that any provision of the Organizational Documents of any such Subsidiary should be deemed to be inconsistent with or to prohibit the granting of the collateral assignment, pledge and Liens to Agent by Domestic Loan Parties in the Pledged Equity Interest Collateral issued by such Subsidiary provided for herein, or the exercise of any of the rights and remedies of and/or proxies or powers of attorney granted to Agent under this Section 4.14, such Organizational Documents of such Pledged Issuer are hereby amended as necessary to allow for such grant and to allow the full exercise by Agent of all such rights and remedies and/or proxies or powers of attorney, and this Agreement shall constitute and be deemed for all purposes and under all circumstances to be an amendment to any such applicable Organizational Document of such Pledged Issuer.

Either (x) if (a) any representation or warranty set forth in (i) Section 16.18(a) hereof or (ii) any corresponding section of any Guaranty is or becomes false or misleading at any time, (b) any Borrower shall fail to comply with its obligations under Section 16.18(b) hereof, or (c) any Guarantor shall fail to comply with its obligations under any section of any Guaranty containing provisions comparable to those set forth in Section 16.18(b) hereof, or (y) with respect to any Loan Party that is party to this Agreement and that is domiciled in Germany (Inländer), the occurrence of any event or circumstances which would have resulted in any representation or warranty set forth in Section 16.18(a) hereof being or becoming false or misleading or which would have constituted a failure by any such Loan Party to comply with the provisions of Section 16.18(b) hereof but for the effects of Section 16.18(c) hereof.

(a)Upon the occurrence of: (i) an Event of Default pursuant to Section 10.7 hereof (other than Section 10.7(g) hereof), all Obligations shall be immediately due and payable (including, without limitation, any applicable fee(s) or other amounts payable under the Fee Letter in connection with or with respect to such acceleration) and this Agreement and the Commitments shall be deemed terminated, (ii) any of the other Events of Default and at any time thereafter, at the option of Agent or at the direction of Required Lenders all Obligations shall be immediately due and payable (including, without limitation, any applicable fee(s) or other amounts payable under the Fee Letter in connection with or with respect to such acceleration) and Agent or Required Lenders shall have the right to terminate this Agreement and to terminate the Commitments; and (iii) without limiting Section 8.2 hereof, any Default under Sections 10.7(g) hereof, the obligation of Lenders to make Advances hereunder shall be suspended until such time as such involuntary petition shall be dismissed. Upon the occurrence of any Event of Default, Agent shall have the right to exercise any and all rights and remedies provided for herein, under the Other Documents, under the Uniform Commercial Code and at law or equity generally, including the right to foreclose the security interests granted herein and to realize upon any Collateral by any available judicial procedure and/or to take possession of and sell any or all of the Collateral with or without judicial process. Agent may enter any of any Loan Party’s premises or other premises without legal process and without incurring liability to any Loan Party therefor, and Agent may thereupon, or at any time thereafter, in its discretion without notice or demand, take the Collateral and remove the same to such place as Agent may deem advisable and Agent may require Loan Parties to make the Collateral available to Agent at a convenient place. With or without having the Collateral at the time or place of sale, Agent may sell the Collateral, or any part thereof, at public or private sale, at any time or place, in one or more sales, at such price or prices, and upon such terms, either for cash, credit or future delivery, as Agent may elect. Except as to that part of the Collateral which is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, Agent shall give Loan Parties reasonable notification of such sale or sales, it being agreed that in all events written notice mailed to Borrowing Agent at least ten (10) days prior to such sale or sales is reasonable notification. At any public sale Agent or any Lender may bid (including credit bid) for and become the purchaser, and Agent, any Lender or any other purchaser at any such sale thereafter shall hold the Collateral sold absolutely free from any claim or right of whatsoever kind, including any equity of redemption and all such claims, rights and equities are hereby expressly waived and released by each Loan Party. In connection with the exercise of the foregoing remedies, including the sale of Inventory, Agent is granted a perpetual non-revocable, royalty free, nonexclusive license and Agent is granted permission to use all of each Loan Party’s (a) Intellectual Property which is used or useful in connection with Inventory for the purpose of marketing, advertising for sale and selling or otherwise disposing of such Inventory and (b) equipment for the purpose of completing the manufacture of unfinished goods. The Net Cash Proceeds realized from the sale of any Collateral shall be applied to the Obligations in the order set forth in Section 11.5 hereof. Non-cash proceeds will only be applied to the Obligations as they are converted into cash. If any deficiency shall arise, Loan Parties shall remain liable to Agent and Lenders therefor.

(b)To the extent that Applicable Law imposes duties on Agent to exercise remedies in a commercially reasonable manner, each Loan Party acknowledges and agrees that it is not commercially unreasonable for Agent: (i) to fail to incur expenses reasonably deemed significant

by Agent to prepare Collateral for disposition or otherwise to complete raw material or work in process into finished goods or other finished products for disposition; (ii) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of; (iii) to fail to exercise collection remedies against Customers or other Persons obligated on Collateral or to remove Liens on or any adverse claims against Collateral; (iv) to exercise collection remedies against Customers and other Persons obligated on Collateral directly or through the use of collection agencies and other collection specialists; (v) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature; (vi) to contact other Persons, whether or not in the same business as any Loan Party, for expressions of interest in acquiring all or any portion of such Collateral; (vii) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature; (viii) to dispose of Collateral by utilizing internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capacity of doing so, or that match buyers and sellers of assets; (ix) to dispose of assets in wholesale rather than retail markets; (x) to disclaim disposition warranties, such as title, possession or quiet enjoyment, (xi) to purchase insurance or credit enhancements to insure Agent against risks of loss, collection or disposition of Collateral or to provide to Agent a guaranteed return from the collection or disposition of Collateral; or (xii) to the extent deemed appropriate by Agent, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist Agent in the collection or disposition of any of the Collateral. Each Loan Party acknowledges that the purpose of this Section 11.1(b) is to provide non-exhaustive indications of what actions or omissions by Agent would not be commercially unreasonable in Agent’s exercise of remedies against the Collateral and that other actions or omissions by Agent shall not be deemed commercially unreasonable solely on account of not being indicated in this Section 11.1(b). Without limitation upon the foregoing, nothing set forth in this Section 11.1(b) shall be construed to grant any rights to any Loan Party or to impose any duties on Agent that would not have been granted or imposed by this Agreement or by Applicable Law in the absence of this Section 11.1(b).

11.2Agent’s Discretion. Agent shall have the right to determine which rights, Liens, security interests or remedies Agent may at any time pursue, relinquish, subordinate, or modify, which procedures, timing and methodologies to employ, and what any other action to take with respect to any or all of the collateral and in what order, thereto and such determination will not in any way modify or affect any of Agent’s or Lenders’ rights hereunder as against Loan Parties or each other.

11.3Setoff. If an Event of Default shall have occurred and be continuing, Agent, each Lender, each Issuer, 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 Agent, such Lender, such Issuer or any such Affiliate, to or for the credit or the account of the Borrowers or any other Loan Party against any and all of the obligations of the Borrowers or any other Loan Party now or hereafter existing under this Agreement or any Other Document to Agent, such Lender or such Issuer or their respective Affiliates, irrespective of whether or not such Lender, Issuer or Affiliate shall have made any demand under this Agreement or any Other Document and although such

obligations of the Borrowers or any other Loan Party may be contingent or unmatured or are owed to a branch, office or Affiliate of Agent, such Lender or such Issuer 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 2.22 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 Issuer, 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 Agent, each Lender, the Issuer and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that Agent, such Lender, the Issuer or their respective Affiliates may have. Agent, each Lender and Issuer agrees to notify the Borrowing Agent 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

11.4Rights and Remedies not Exclusive. The enumeration of the foregoing rights and remedies is not intended to be exhaustive and the exercise of any rights or remedy shall not preclude the exercise of any other right or remedies provided for herein or otherwise provided by law, all of which shall be cumulative and not alternative.

11.5Allocation of Payments and Proceeds of Collateral after Event of Default. Notwithstanding any provisions of this Agreement to the contrary:

(a)After the occurrence and during the continuance of an Event of Default, all amounts collected or received by Agent on account of the Obligations (including without limitation any amounts on account of any of Cash Management Liabilities or Hedge Liabilities, adequate protection payments and distributions under a plan of reorganization), or in respect of the Collateral may be paid, at Agent’s discretion, over or delivered as follows:

Each Loan Party hereby waives notice of non-payment of any of the Receivables, demand, presentment, protest and notice thereof with respect to any and all instruments, notice of acceptance hereof, notice of loans or advances made, credit extended, Collateral received or delivered, or any other action taken in reliance hereon, and all other demands and notices of any description, except such as are expressly provided for herein.

12.3Jury Waiver. EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, COUNTERCLAIM, DEMAND, ACTION OR CAUSE OF ACTION (A) ARISING UNDER THIS AGREEMENT, ANY OTHER DOCUMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR (B) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF THEM WITH RESPECT TO THIS AGREEMENT, ANY OTHER DOCUMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE AND EACH PARTY HEREBY CONSENTS THAT ANY SUCH CLAIM, COUNTERCLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENTS OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

13.1Term. This Agreement, which shall inure to the benefit of and shall be binding upon the respective successors and permitted assigns of each Loan Party, Agent and each Lender, shall become effective on the Closing Date and shall continue in full force and effect until the third anniversary of the Closing Date (the “Term”), unless sooner terminated as herein provided. Borrowers may terminate this Agreement at any time upon ninety (90) days prior written notice to Agent upon Payment in Full of the Obligations.

13.2Termination. The termination of this Agreement shall not affect Agent’s or any Lender’s rights, or any of the Obligations having their inception prior to the effective date of such termination or any Obligations which pursuant to the terms hereof continue to accrue after such date, and the provisions hereof shall continue to be fully operative until all transactions entered into, rights or interests created and all of the Obligations have been Paid in Full. The security interests, Liens and rights granted to Agent and Lenders hereunder and the financing statements filed in connection herewith shall continue in full force and effect, notwithstanding the termination of this Agreement or the fact that Borrowers’ Account may from time to time be temporarily in a zero or credit position, until (a) all of the Obligations have Paid in Full, the Commitments and this Agreement and the Other Documents have been terminated and each Loan Party has provided Agent and Lenders with an indemnification satisfactory to Agent with respect thereto, and (b) all of the Loan Parties have released Agent and the other Secured Parties from and against any and all claims of any nature whatsoever that any Loan Party may have against Secured Parties pursuant to a release in form and substance acceptable to Agent. Accordingly, each Loan Party waives any rights which it may have under the Uniform Commercial Code to demand the filing of termination statements with respect to the Collateral, and Agent shall not be required to send such termination statements to each Loan Party, or to file them with any filing office, unless and until this Agreement shall have been terminated in accordance with its terms, all Obligations have been Paid in Full, and all of the Loan Parties have released Agent and the other Secured Parties from and against any and all claims of any nature whatsoever that any Loan Party may have against Agent

and such other Secured Parties pursuant to a release in form and substance acceptable to Agent (the “Release Conditions”). Upon satisfaction of the Release Conditions all security interests and liens granted to Agent under this Agreement and the Other Documents shall be automatically released and terminated. All representations, warranties, covenants, waivers and agreements set forth herein shall survive the termination of this Agreement and the Payment in Full of the Obligations.

Agent hereby agrees with the Borrowers that Agent shall (and the Lenders hereby direct the Agent to), upon the request of the Borrowing Agent: (a) release any Lien on any Collateral granted to or held by Agent under any Loan Document (i) upon satisfaction of the Release Conditions, (ii) that is transferred or to be transferred as part of or in connection with any Disposition permitted hereunder or under any other Loan Document, or (iii) as approved in accordance with Section 16.2(b) of this Agreement; and (b) release any Guarantor from its obligations under this Agreement and the Other Documents if such Person ceases to be a Subsidiary of DZSI as a result of a transaction permitted hereunder.

14.1Appointment. Each Lender hereby designates PNC to act as Agent for such Lender under this Agreement and the Other Documents. Each Lender hereby irrevocably authorizes Agent to take such action on its behalf under the provisions of this Agreement and the Other Documents and to exercise such powers and to perform such duties hereunder and thereunder as are specifically delegated to or required of Agent by the terms hereof and thereof and such other powers as are reasonably incidental thereto and Agent shall hold all Collateral, payments of principal and interest, fees (except the fees set forth in Sections 2.8(b) and 3.4 hereof and in the Fee Letter), charges and collections received pursuant to this Agreement, for the ratable benefit of Lenders. Agent may perform any of its duties hereunder by or through its agents or employees. As to any matters not expressly provided for by this Agreement, Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of Required Lenders, and such instructions shall be binding; provided, however, that Agent shall not be required to take any action which, in Agent’s discretion, exposes Agent to liability or which is contrary to this Agreement or the Other Documents or Applicable Law unless Agent is provided with an indemnification reasonably satisfactory to Agent with respect thereto.

14.2Nature of Duties. Agent shall have no duties or responsibilities except those expressly set forth in this Agreement and the Other Documents. Neither Agent nor any of its officers, directors, employees or agents shall be (i) liable for any action taken or omitted by them as such hereunder or in connection herewith, unless caused by their gross (not mere) negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment), or (ii) responsible in any manner for any recitals, statements, representations or warranties made by any Loan Party or any officer thereof set forth in this Agreement, or in any of the Other Documents or in any certificate, report, statement or other document referred to or provided for in, or received by Agent under or in connection with, this Agreement or any of the Other Documents or for the value, validity, effectiveness, genuineness, due execution, enforceability or sufficiency of this Agreement, or any of the Other Documents or for any failure of any Loan Party to perform its obligations hereunder. Agent shall not be under any obligation

to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements set forth in, or conditions of, this Agreement or any of the Other Documents, or to inspect the properties, books or records of any Loan Party. The duties of Agent as respects the Advances to Borrowers shall be mechanical and administrative in nature. Agent shall not have by reason of this Agreement a fiduciary relationship in respect of any Lender and nothing in this Agreement, expressed or implied, is intended to or shall be so construed as to impose upon Agent any obligations in respect of this Agreement or the transactions described herein except as expressly set forth herein.

14.3Lack of Reliance on Agent. Independently and without reliance upon Agent or any other Lender, each Lender has made and shall continue to make (i) its own independent investigation of the financial condition and affairs of each Loan Party in connection with the making and the continuance of the Advances hereunder and the taking or not taking of any action in connection herewith, and (ii) its own appraisal of the creditworthiness of each Loan Party. Agent shall have no duty or responsibility, either initially or on a continuing basis, to provide any Lender with any credit or other information with respect thereto, whether coming into its possession before making of the Advances or at any time or times thereafter except as shall be provided by any Loan Party pursuant to the terms hereof. Agent shall not be responsible to any Lender for any recitals, statements, information, representations or warranties herein or in any agreement, document, certificate or a statement delivered in connection with or for the execution, effectiveness, genuineness, validity, enforceability, collectability or sufficiency of this Agreement or any Other Document, or of the financial condition of any Loan Party, or be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of this Agreement, the Notes, the Other Documents or the financial condition or prospects of any Loan Party, or the existence of any Event of Default or any Default.

14.4Resignation of Agent; Successor Agent; Resignation of Non-Agent Issuing Bank. Agent may resign on sixty (60) days written notice to each of Lenders and Borrowing Agent and upon such resignation, Required Lenders will promptly designate a successor Agent reasonably satisfactory to Borrowing Agent (provided that no such approval by Borrowing Agent shall be required (i) in any case where the successor Agent is one of Lenders or (ii) after the occurrence and during the continuance of any Event of Default) ; provided that in no event shall any such successor Agent be a Defaulting Lender. Any such successor Agent shall succeed to the rights, powers and duties of Agent, and shall in particular succeed to all of Agent’s right, title and interest in and to all of the Liens in the Collateral securing the Obligations created hereunder or any Other Document, and the term “Agent” shall mean such successor agent effective upon its appointment, and the former Agent’s rights, powers and duties as Agent shall be terminated, without any other or further act or deed on the part of such former Agent. However, notwithstanding the foregoing, if at the time of the effectiveness of the new Agent’s appointment, any further actions need to be taken in order to provide for the legally binding and valid transfer of any Liens in the Collateral from former Agent to new Agent and/or for the perfection of any Liens in the Collateral as held by new Agent or it is otherwise not then possible for new Agent to become the holder of a fully valid, enforceable and perfected Lien as to any of the Collateral, former Agent shall continue to hold such Liens solely as agent for perfection of such Liens on behalf of new Agent until such time as new Agent can obtain a fully valid, enforceable and perfected Lien on all Collateral, provided that Agent shall not be required to or have any liability or responsibility to take any further actions after such date as such agent for perfection to continue the perfection of any such

Liens (other than to forego from taking any affirmative action to release any such Liens). After Agent’s resignation as Agent, the provisions of this Article XIV, and any indemnification rights under this Agreement, including without limitation, rights arising under Section 16.5 hereof, shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement (and in the event resigning Agent continues to hold any Liens pursuant to the provisions of the immediately preceding sentence, the provisions of this Article XIV and any indemnification rights under this Agreement, including without limitation, rights arising under Section 16.5 hereof, shall inure to its benefit as to any actions taken or omitted to be taken by it in connection with such Liens).

Any Issuer (other than PNC) may resign its capacity as an Issuer hereunder on ten (10) days written notice to each of Lenders and Borrowing Agent, and upon the effectiveness of such resignation, such resigning Issuer shall have no further commitment, obligation, or duty to issue any new Letters of Credit hereunder and/or to consent to any modifications or amendments or increases to any Letter of Credit issued by such resigning Issuer prior to the effectiveness of such resignation and/or to extend the maturity or term of any Letter of Credit issued by such resigning Issuer prior to the effectiveness of such resignation (and/or to permit any “evergreen” Letter of Credit issued by such resigning Issuer prior to the effectiveness of such resignation to renew); provided that, such resigning Issuer shall remain an Issuer for all purposes hereunder and under the Other Documents with respect to the Letters of Credit issued by such resigning Issuer prior to the effectiveness of such resignation until each such prior-issued Letter of Credit (x) has been fully drawn, (y) expires and/or terminates in accordance with the terms thereof, or (y) is cancelled/terminated and returned to such resigning Issuer with the consent of the beneficiary thereof. After any Issuer’s resignation as Issuer under the provisions of this paragraph, the provisions of this Article XIV, and any indemnification rights under this Agreement, including without limitation, rights arising under Section 16.5 hereof, shall inure to its benefit as to any actions taken or omitted to be taken by it while it was an Issuer under this Agreement as to any Letter of Credit.

14.5Certain Rights of Agent. If Agent shall request instructions from Lenders with respect to any act or action (including failure to act) in connection with this Agreement or any Other Document, Agent shall be entitled to refrain from such act or taking such action unless and until Agent shall have received instructions from Required Lenders; and Agent shall not incur liability to any Person by reason of so refraining. Without limiting the foregoing, Lenders shall not have any right of action whatsoever against Agent as a result of its acting or refraining from acting hereunder in accordance with the instructions of Required Lenders.

14.6Reliance. Agent shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, statement, certificate, email, facsimile or telecopier message, order or other document or telephone message believed by it to be genuine and correct and to have been signed, sent or made by the proper person or entity, and, with respect to all legal matters pertaining to this Agreement and the Other Documents and its duties hereunder, upon advice of counsel selected by it. Agent may employ agents and attorneys-in-fact and shall not be liable for the default or misconduct of any such agents or attorneys-in-fact selected by Agent with reasonable care.

14.7Notice of Default. Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder or under the Other Documents, unless Agent has received notice from a Lender or Borrowing Agent referring to this Agreement or the Other Documents, describing such Default or Event of Default and stating that such notice is a “notice of default”. In the event that Agent receives such a notice, Agent shall give notice thereof to Lenders. Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by Required Lenders; provided, that, unless and until Agent shall have received such directions, Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of Lenders.

14.8Indemnification. To the extent Agent is not reimbursed and indemnified by Loan Parties, each Lender will reimburse and indemnify Agent in proportion to its respective portion of the outstanding Advances and its respective Participation Commitments in the outstanding Letters of Credit and outstanding Swing Loans (or, if no Advances are outstanding, pro rata according to the percentage that its Revolving Commitment Amount constitutes of the total aggregate Revolving Commitment Amounts), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against Agent in performing its duties hereunder, or in any way relating to or arising out of this Agreement or any Other Document; provided that Lenders shall not be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from Agent’s gross (not mere) negligence or willful misconduct (as determined by a court of competent jurisdiction in a final non-appealable judgment).

14.9Agent in its Individual Capacity. With respect to the obligation of Agent to lend under this Agreement, the Advances made by it shall have the same rights and powers hereunder as any other Lender and as if it were not performing the duties as Agent specified herein; and the term “Lender” or any similar term shall, unless the context clearly otherwise indicates, include Agent in its individual capacity as a Lender. Agent may engage in business with any Loan Party as if it were not performing the duties specified herein, and may accept fees and other consideration from any Loan Party for services in connection with this Agreement or otherwise without having to account for the same to Lenders.

14.10Delivery of Documents. To the extent Agent receives financial statements required under Sections 9.7, 9.8, 9.9, 9.12 and 9.13 hereof or Borrowing Base Certificates from any Loan Party pursuant to the terms of this Agreement which any Loan Party is not obligated to deliver to each Lender, Agent will promptly deliver such documents and information to Lenders.

14.11Loan Parties’ Undertaking to Agent. Without prejudice to their respective obligations to Lenders under the other provisions of this Agreement, each Loan Party hereby undertakes with Agent to pay to Agent from time to time on demand all amounts from time to time due and payable by it for the account of Agent or Lenders or any of them pursuant to this Agreement to the extent not already paid. Any payment made pursuant to any such demand shall pro tanto satisfy the relevant Loan Party’s obligations to make payments for the account of Lenders or the relevant one or more of them pursuant to this Agreement.

14.12No Reliance on Agent’s Customer Identification Program. To the extent the Advances or this Agreement is, or becomes, syndicated in cooperation with other Lenders, each Lender acknowledges and agrees that neither such Lender, nor any of its Affiliates, participants or assignees, may rely on Agent to carry out such Lender's, Affiliate's, participant's or assignee's customer identification program, or other obligations required or imposed under or pursuant to the USA PATRIOT Act or the regulations thereunder, including the regulations contained in 31 CFR 103.121 (as hereafter amended, modified, supplemented or replaced, the “CIP Regulations”), or any other Anti-Terrorism Law, including any programs involving any of the following items relating to or in connection with any of Loan Parties, their Affiliates or their agents, the Other Documents or the transactions hereunder or contemplated hereby: (i) any identity verification procedures, (ii) any recordkeeping, (iii) comparisons with government lists, (iv) customer notices or (v) other procedures required under the CIP Regulations or such Anti-Terrorism Laws.

14.13Other Agreements. Each of Lenders agrees that it shall not, without the prior written consent of Agent, and that it shall, to the extent it is lawfully entitled to do so, upon the request of Agent, set off against the Obligations, any amounts owing by such Lender to any Loan Party or any deposit accounts of any Loan Party now or hereafter maintained with such Lender. Anything in this Agreement to the contrary notwithstanding, each of Lenders further agrees that it shall not, unless specifically requested to do so by Agent, take any action to protect or enforce its rights arising out of this Agreement or the Other Documents, it being the intent of Lenders that any such action to protect or enforce rights under this Agreement and the Other Documents shall be taken in concert and at the direction or with the consent of Agent or Required Lenders.

(a)Each Loan Party hereby irrevocably designates Borrowing Agent to be its attorney and agent and in such capacity whether verbally, in writing or through electronic methods (including, without limitation, an Approved Electronic Communication) to (i) borrow, (ii) request advances, (iii) request the issuance of Letters of Credit, (iv) sign and endorse notes, (v) execute and deliver all instruments, documents, applications, security agreements, reimbursement agreements and letter of credit agreements for Letters of Credit and all other agreements, documents, instruments, certificates, notices, writings and further assurances now or hereafter required hereunder, (vi) make elections regarding interest rates, (vii) give instructions regarding Letters of Credit and agree with Issuer upon any amendment, extension or renewal of any Letter of Credit and (viii) otherwise take action under and in connection with this Agreement and the Other Documents, all on behalf of and in the name of such Loan Party or Loan Parties, and hereby authorizes Agent to pay over or credit all loan proceeds hereunder in accordance with the request of Borrowing Agent.

(b)The handling of this credit facility as a co-borrowing facility with a borrowing agent in the manner set forth in this Agreement is solely as an accommodation to Loan Parties and at their request. Neither Agent nor any Lender shall incur liability to Loan Parties as a result thereof. To induce Agent and Lenders to do so and in consideration thereof, each Loan Party hereby indemnifies Agent and each Lender and holds Agent and each Lender harmless from and against any and all liabilities, expenses, losses, damages and claims of damage or injury asserted against

Agent or any Lender by any Person arising from or incurred by reason of the handling of the financing arrangements of Loan Parties as provided herein, reliance by Agent or any Lender on any request or instruction from Borrowing Agent or any other action taken by Agent or any Lender with respect to this Section 15.1 except due to willful misconduct or gross (not mere) negligence by the indemnified party (as determined by a court of competent jurisdiction in a final and non-appealable judgment).

(c)All Obligations shall be joint and several, and each Borrower shall make payment upon the maturity of the Obligations by acceleration or otherwise, and such obligation and liability on the part of each Borrower shall in no way be affected by any extensions, renewals and forbearance granted by Agent or any Lender to any Loan Party, failure of Agent or any Lender to give any Loan Party notice of borrowing or any other notice, any failure of Agent or any Lender to pursue or preserve its rights against any Loan Party, the release by Agent or any Lender of any Collateral now or thereafter acquired from any Loan Party, and such agreement by each Borrower to pay upon any notice issued pursuant thereto is unconditional and unaffected by prior recourse by Agent or any Lender to the other Loan Parties or any Collateral for such Borrower’s Obligations or the lack thereof. Each Borrower waives all suretyship defenses.

15.2Waiver of Subrogation. Each Loan Party expressly waives any and all rights of subrogation, reimbursement, indemnity, exoneration, contribution of any other claim which such Loan Party may now or hereafter have against the other Loan Parties or any other Person directly or contingently liable for the Obligations hereunder, or against or with respect to any other Loan Party’s property (including, without limitation, any property which is Collateral for the Obligations), arising from the existence or performance of this Agreement, until the termination of the Commitments, the termination of this Agreement and the Payment in Full of the Obligations.

16.1Governing Law. This Agreement and each Other Document (unless and except to the extent expressly provided otherwise in any such Other Document), and all matters relating hereto or thereto or arising herefrom or therefrom (whether arising under contract law, tort law or otherwise) shall, in accordance with Section 5-1401 of the General Obligations Law of the State of New York, be governed by and construed in accordance with the laws of the State of New York. Any judicial proceeding brought against any Loan Party with respect to any of the Obligations, this Agreement or any of the Other Documents may be brought in any court of competent jurisdiction in the State of New York, United States of America, and, by execution and delivery of this Agreement, each Loan Party accepts for itself and in connection with its properties, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid courts, and irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement. Each Loan Party hereby waives personal service of any and all process upon it and consents that all such service of process may be made by hand delivery or delivery (prepaid) by internationally recognized overnight courier to Borrowing Agent at its address set forth in Section 16.6 hereof and service so made shall be deemed completed five (5) days after the same shall have been so deposited in the mails of the United States of America, or, at Agent’s option, by service upon Borrowing Agent which each Loan Party irrevocably appoints as such Loan Party’s Agent for the purpose of accepting service within the State of New York. Nothing herein shall affect the right to serve process in any manner permitted by law or shall limit the right of Agent or any Lender to

bring proceedings against any Loan Party in the courts of any other jurisdiction. Each Loan Party waives any objection to jurisdiction and venue of any action instituted hereunder and shall not assert any defense based on lack of jurisdiction or venue or based upon forum non conveniens. Each Loan Party waives the right to remove any judicial proceeding brought against such Loan Party in any state court to any federal court. Any judicial proceeding by any Loan Party against Agent or any Lender involving, directly or indirectly, any matter or claim in any way arising out of, related to or connected with this Agreement or any of the Other Documents shall be brought only in a federal or state court located in the County of New York, State of New York.

(a)This Agreement and the Other Documents contain the entire understanding between each Loan Party, Agent and each Lender and supersedes all prior agreements and understandings, if any, relating to the subject matter hereof. Any promises, representations, warranties or guarantees not herein contained and hereinafter made shall have no force and effect unless in writing, signed by each Loan Party’s, Agent’s and each Lender’s respective officers. Neither this Agreement nor any portion or provisions hereof may be amended, modified, waived, supplemented, discharged, cancelled or terminated orally or by any course of dealing, or in any manner other than by an agreement in writing, signed by the party to be charged. Notwithstanding the foregoing, Agent may modify this Agreement or any of the Other Documents for the purposes of completing missing content or correcting erroneous content of an administrative nature, without the need for a written amendment, provided that Agent shall send a copy of any such modification to Loan Parties and each Lender (which copy may be provided by electronic mail). Each Loan Party acknowledges that it has been advised by counsel in connection with the execution of this Agreement and Other Documents and is not relying upon oral representations or statements inconsistent with the terms and provisions of this Agreement.

(b)Subject to the provisions of this Section 16.2(b), the conditions, provisions or terms hereof or of any Other Document may be amended, modified, supplemented, changed, varied, made the subject of any consent, or waived in any manner upon consent of Required Lenders, Agent, and Loan Parties and the execution by them of a written amendments or other agreements, documents or instruments providing for the terms of such amendment, modification, supplement, change, variation, consent, or waiver; provided, however, that no such amendment, or other agreement, document or instrument shall:

(i)increase the Revolving Commitment or any Term Loan Commitment, as applicable, or the maximum dollar amount of the Revolving Commitment Amount or any Term Loan Commitment Amount, as applicable of any Lender without the consent of such Lender directly affected thereby;

(ii)whether or not any Advances are outstanding, extend the Term or the time for payment of principal or interest of any Advance (excluding the due date of any mandatory prepayment of an Advance), or any fee payable to any Lender, or reduce the principal amount of or the rate of interest borne by any Advances or reduce any fee payable to any Lender, without the consent of each Lender directly affected thereby (except that Required Lenders may elect to waive or rescind any imposition of the Default Rate under

Section 3.1 hereof or Letter of Credit Default Rate under Section 3.2 hereof (unless imposed by Agent));

(iii)except in connection with any increase pursuant to Section 2.24 hereof, increase the Maximum Revolving Advance Amount without the consent of all Revolving Lenders;

(iv)alter the definition of the term “Required Lenders” or alter, amend or modify this Section 16.2(b) without the consent of all Lenders;

(v)alter, amend or modify the provisions of Section 11.5 hereof without the consent of all Lenders;

(vi)release any Collateral during any calendar year (other than in accordance with the provisions of this Agreement) having an aggregate value in excess of $3,000,000 without the consent of all Lenders, except in connection with a Permitted Disposition;

(vii)change the rights and duties of Agent without the consent of all Lenders and Agent;

(viii)subject to clause (e) below, permit any Revolving Advance to be made if after giving effect thereto the total of Revolving Advances outstanding hereunder would exceed the Formula Amount for more than sixty (60) consecutive Business Days or exceed one hundred and ten percent (110%) of the Formula Amount without the consent of all Revolving Lenders;

(ix)increase the Advance Rates above the Advance Rates in effect on the Closing Date without the consent of all Revolving Lenders; or

(c)Any such supplemental agreement shall apply equally to each Lender and shall be binding upon Loan Parties, Lenders and Agent and all future holders of the Obligations. In the case of any waiver, Loan Parties, Agent and Lenders shall be restored to their former positions and rights, and any Event of Default waived shall be deemed to be cured and not continuing, but no waiver of a specific Event of Default shall extend to any subsequent Event of Default (whether or not the subsequent Event of Default is the same as the Event of Default which was waived), or impair any right consequent thereon.

(d)In the event that Agent requests the consent of a Lender pursuant to this Section 16.2 and (x) such consent is denied and (y) Required Lenders have approved such consent, then Agent may require such Lender to assign its interest in the Advances to Agent or to another Lender or to any other Person designated by Agent (the “Designated Lender”), for a price equal to (i) then outstanding principal amount thereof plus (ii) accrued and unpaid interest and fees due such Lender, which interest and fees shall be paid when collected from Borrowers. In the event Agent elects to require any Lender to assign its interest to Agent or to the Designated Lender, Agent will so notify such Lender in writing within forty five (45) days following such Lender’s denial, and such Lender will assign its interest to Agent or the Designated Lender no later than five (5) days

following receipt of such notice pursuant to a Commitment Transfer Supplement executed by such Lender, Agent or the Designated Lender, as appropriate, and Agent.

(e)Notwithstanding (i) the existence of a Default or an Event of Default, (ii) that any of the other applicable conditions precedent set forth in Section 8.2 hereof have not been satisfied or the Revolving Commitments have been terminated for any reason, or (iii) any other contrary provision of this Agreement, Agent may, without the consent of any Lender, voluntarily permit the outstanding Revolving Advances at any time to exceed an amount equal to the Formula Amount by up to ten percent (10%) of the Formula Amount for up to sixty (60) consecutive Business Days (the “Out-of-Formula Loans”); provided that no such Out-of-Formula Loan may be made to the extent, after giving effect to such Out-of-Formula Loan, the aggregate principal amount of the Revolving Loans (including any Out-of-Formula Loans and any Protective Advances) and Swing Loans then-outstanding plus the Maximum Undrawn Amount of all Letters of Credit then-outstanding plus the Ex-Im Subfacility Outstandings Amount would exceed the Maximum Revolving Advance Amount. If Agent is willing in its sole and absolute discretion to permit such Out-of-Formula Loans, the Revolving Lenders shall be obligated to fund such Out-of-Formula Loans in accordance with their respective Revolving Commitment Percentages, and such Out-of-Formula Loans shall be payable on demand and shall bear interest at the Default Rate; provided that, if Agent does permit Out-of-Formula Loans, neither Agent nor Lenders shall be deemed thereby to have changed the limits of Section 2.1(a) and further provided that, no Revolving Lender shall be required to fund any portion of any Out-of-Formula Loan to the extent that, after giving effect to such funding, the aggregate amount of the outstanding Revolving Advances funded by such Revolving Lender (including any Out-of-Formula Loans and/or Protective Advances funded by such Revolving Lender) plus such Revolving Lender’s Revolving Commitment Percentage of all outstanding Swing Loans plus such Revolving Lender’s Revolving Commitment Percentage of the aggregate Maximum Undrawn Amount of all outstanding Letters of Credit plus such Lender’s Ex-Im Revolving Commitment Percentage of the Ex-Im Subfacility Outstandings Amount would exceed the Revolving Commitment Amount of such Lender. For purposes of this paragraph, the discretion granted to Agent hereunder shall not preclude involuntary overadvances that may result from time to time due to the fact that the Formula Amount was unintentionally exceeded for any reason, including, but not limited to, Collateral previously deemed to be Eligible Receivables (or Eligible Foreign Receivables) becomes ineligible, collections of Receivables applied to reduce outstanding Revolving Advances are thereafter returned for insufficient funds or overadvances are made to protect or preserve the Collateral. In the event Agent involuntarily permits the outstanding Revolving Advances to exceed the Formula Amount by more than ten percent (10%), Agent shall use its efforts to have Borrowers decrease such excess in as expeditious a manner as is practicable under the circumstances and not inconsistent with the reason for such excess. Revolving Advances made after Agent has determined the existence of involuntary overadvances shall be deemed to be involuntary overadvances and shall be decreased in accordance with the preceding sentence. To the extent any Out-of-Formula Loans are not actually funded by the other Lenders as provided for in this Section 16.2(e), Agent may elect in its discretion to fund such Out-of-Formula Loans and any such Out-of-Formula Loans so funded by Agent shall be deemed to be Revolving Advances made by and owing to Agent, and Agent shall be entitled to all rights (including accrual of interest) and remedies of a Revolving Lender under this Agreement and the Other Documents with respect to such Revolving Advances.

(f)In addition to (and not in substitution of) the discretionary Revolving Advances permitted above in this Section 16.2, (A) Agent is hereby authorized by Borrowers and Lenders, at any time in Agent’s sole discretion regardless of (i) the existence of a Default or an Event of Default, (ii) whether any of the other applicable conditions precedent set forth in Section 8.2 hereof have not been satisfied or the Revolving Commitments have been terminated for any reason, or (iii) any other contrary provision of this Agreement, to make Revolving Advances to Borrowers on behalf of Lenders which Agent, in its reasonable business judgment, deems necessary or desirable (a) to preserve or protect the Collateral, or any portion thereof, (b) to enhance the likelihood of, or maximize the amount of, repayment of the Advances and other Obligations, or (c) to pay any other amount chargeable to Borrowers pursuant to the terms of this Agreement (any such Revolving Advances, the “Protective Advances”), provided that, no such Protective Advance may be made to the extent, after giving effect to such Protective Advance, the aggregate principal amount of the Revolving Loans (including any Out-of-Formula Loans and any Protective Advances) and Swing Loans then-outstanding plus the Maximum Undrawn Amount of all Letters of Credit then-outstanding plus the Ex-Im Subfacility Outstandings Amount would exceed the Maximum Revolving Advance Amount. The Revolving Lenders shall be obligated to fund such Protective Advances and effect a settlement with Agent therefore upon demand of Agent in accordance with their respective Revolving Commitment Percentages; provided that, no Revolving Lender shall be required to fund any portion of any Protective Advance to the extent that, after giving effect to such funding, the aggregate amount of the outstanding Revolving Advances funded by such Revolving Lender (including any Out-of-Formula Loans and/or Protective Advances funded by such Revolving Lender) plus such Revolving Lender’s Revolving Commitment Percentage of all outstanding Swing Loans plus such Revolving Lender’s Revolving Commitment Percentage of the aggregate Maximum Undrawn Amount of all outstanding Letters of Credit plus such Lender’s Ex-Im Revolving Commitment Percentage of the Ex-Im Subfacility Outstandings Amount would exceed the Revolving Commitment Amount of such Lender. To the extent any Protective Advances are not actually funded by the other Lenders as provided for in this Section 16.2(f), any such Protective Advances funded by Agent shall be deemed to be Revolving Advances made by and owing to Agent, and Agent shall be entitled to all rights (including accrual of interest) and remedies of a Revolving Lender under this Agreement and the Other Documents with respect to such Revolving Advances.

(a)This Agreement shall be binding upon and inure to the benefit of Loan Parties, Agent, each Lender, all future holders of the Obligations and their respective successors and assigns, except that no Loan Party may assign or transfer any of its rights or obligations under this Agreement without the prior written consent of Agent and each Lender.

(b)Each Loan Party acknowledges that in the regular course of commercial banking business one or more Lenders may at any time and from time to time sell participating interests in the Advances to other Persons (each such transferee or purchaser of a participating interest, a “Participant”). Each Participant may exercise all rights of payment (including rights of set-off) with respect to the portion of such Advances held by it or other Obligations payable hereunder as fully as if such Participant were the direct holder thereof provided that (i) Borrowers shall not be required to pay to any Participant more than the amount which it would have been required to pay to Lender which granted an interest in its Advances or other Obligations payable hereunder to such

Participant had such Lender retained such interest in the Advances hereunder or other Obligations payable hereunder unless the sale of the participation to such Participant is made with Borrower’s prior written consent, and (ii) in no event shall Borrowers be required to pay any such amount arising from the same circumstances and with respect to the same Advances or other Obligations payable hereunder to both such Lender and such Participant. Each Loan Party hereby grants to any Participant a continuing security interest in any deposits, moneys or other property actually or constructively held by such Participant as security for the Participant’s interest in the Advances.

(c)Any Lender may sell, assign or transfer all or any part of its rights and obligations under or relating to any of the Advances or Commitments of such Lender under this Agreement and the Other Documents to one or more entities (each a “Purchasing Lender”), in minimum amounts of not less than $2,500,000, pursuant to a Commitment Transfer Supplement, executed by a Purchasing Lender, the transferor Lender, and Agent (Agent’s consent not to be unreasonably withheld or delayed) and delivered to Agent for recording, provided, however, each such sale, assignment or transfer by any Lender must consist of an assignment by such Lender of an equal percentage of such Lender’s Revolving Commitment and/or Revolving Advances and interests hereunder as a Revolving Lender and of such Lender’s portion of the Term Loan and interest hereunder as a Term Lender. Upon such execution, delivery, acceptance and recording, from and after the transfer effective date determined pursuant to such Commitment Transfer Supplement, (i) Purchasing Lender thereunder shall be a party hereto and, to the extent provided in such Commitment Transfer Supplement, have the rights and obligations of a Lender hereunder with respect to the Advances and, if applicable, Commitments transferred to such Purchasing Lender under such Commitment Transfer Supplement, and (ii) the transferor Lender thereunder shall, to the extent provided in such Commitment Transfer Supplement, be released from its obligations under this Agreement. Such Commitment Transfer Supplement shall be deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the addition of such Purchasing Lender and the resulting adjustment of the Revolving Commitment Percentages arising from the purchase by such Purchasing Lender of all or a portion of the rights and obligations of such transferor Lender under this Agreement and the Other Documents. Each Loan Party hereby consents to the addition of such Purchasing Lender and the resulting adjustment of the Revolving Commitment Percentages arising from the purchase by such Purchasing Lender of all or a portion of the rights and obligations of such transferor Lender under this Agreement and the Other Documents. Loan Parties shall execute and deliver such further documents and do such further acts and things in order to effectuate the foregoing; provided, however, that the consent of Borrowers (such consent not to be unreasonably withheld or delayed) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment or (y) such assignment is to a Permitted Assignee; provided that Borrowers shall be deemed to have consented to any such assignment unless Borrowing Agent shall object thereto by written notice to Agent within five (5) Business Days after having received prior notice thereof.

(d)Any Lender, with the consent of Agent, which shall not be unreasonably withheld or delayed, may directly or indirectly sell, assign or transfer all or any portion of its rights and obligations under or relating to any of the Advances or Commitments of such Lender under this Agreement and the Other Documents to an entity, whether a corporation, partnership, trust, limited liability company or other entity that (i) is a Fund and (ii) is administered, serviced or managed by the assigning Lender or an Affiliate of such Lender (a “Purchasing CLO” and together with each Participant and Purchasing Lender, each a “Transferee” and collectively the “Transferees”),

pursuant to a Commitment Transfer Supplement modified as appropriate to reflect the interest being assigned (“Modified Commitment Transfer Supplement”), executed by any intermediate purchaser, the Purchasing CLO, the transferor Lender, and Agent as appropriate and delivered to Agent for recording, provided, however, each such sale, assignment or transfer by any Revolving Lender prior to the termination of such Revolving Lender’s Revolving Commitment must consist of an assignment by such Revolving Lender of both the designated portion of such Revolving Lender’s Revolving Commitment and Revolving Advances and of that portion of the Term Loan held by such Lender as is proportionate to that portion of such Revolving Lender’s Revolving Commitment and Revolving Advances so sold, assigned or transferred. Upon such execution and delivery, from and after the transfer effective date determined pursuant to such Modified Commitment Transfer Supplement, (i) Purchasing CLO thereunder shall be a party hereto and, to the extent provided in such Modified Commitment Transfer Supplement, have the rights and obligations of a Lender thereunder with respect to the Advances and, if applicable, Commitments transferred to such Purchasing CLO under such Commitment Transfer Supplement, and (ii) the transferor Lender thereunder shall, to the extent provided in such Modified Commitment Transfer Supplement, be released from its obligations under this Agreement. Such Modified Commitment Transfer Supplement shall be deemed to amend this Agreement to the extent, and only to the extent, necessary to reflect the addition of such Purchasing CLO. Each Loan Party hereby consents to the addition of such Purchasing CLO. Loan Parties shall execute and deliver such further documents and do such further acts and things in order to effectuate the foregoing.

(e)Agent shall maintain at its address a copy of each Commitment Transfer Supplement and Modified Commitment Transfer Supplement delivered to it and a register (the “Register”) for the recordation of the names and addresses of each Lender and the outstanding principal, accrued and unpaid interest and other fees due hereunder. The entries in the Register shall be conclusive, in the absence of manifest error, and each Loan Party, Agent and Lenders may treat each Person whose name is recorded in the Register as the owner of the Advance recorded therein for the purposes of this Agreement. The Register shall be available for inspection by Borrowing Agent or any Lender at any reasonable time and from time to time upon reasonable prior notice. Agent shall receive a fee in the amount of $3,500 payable by the applicable Purchasing Lender and/or Purchasing CLO upon the effective date of each transfer or assignment (other than to an intermediate purchaser or to a Permitted Assignee) to such Purchasing Lender and/or Purchasing CLO and the resulting adjustment of the Revolving Commitment Percentages.

(f)Each Loan Party authorizes each Lender to disclose to any Transferee and any prospective Transferee any and all financial information in such Lender’s possession concerning such Loan Party which has been delivered to such Lender by or on behalf of such Loan Party pursuant to this Agreement or in connection with such Lender’s credit evaluation of such Loan Party.

(g)Notwithstanding anything to the contrary set forth in this Agreement, any Lender may at any time and from time to 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.

(h)Notwithstanding anything to the contrary contained in this Section 16.3 (specifically including subsections (b), (c) or (d) hereof) or otherwise provided for in this Agreement or any Other Document including any Note, no Lender may sell any participating interest in its Revolving Commitment and/or its interest in the Revolving Advances (and in its Participation Commitment with respect to Swing Loans and Letters of Credit) to any Participant, and no Lender may sell, assign or transfer all or any part of its rights and obligations under or relating to its Revolving Commitment and/or its interest in the Revolving Advances (and in its Participation Commitment with respect to Swing Loans and Letters of Credit) to any Purchasing Lender or any Purchasing CLO, unless Lender shall also simultaneously sell, assign or transfer (as applicable) to the applicable Participant, Purchasing Lender or Purchasing CLO a corresponding participation interest or transferred interest (as applicable) in such participating/transferring Lender’s Ex-Im Revolving Commitment as an Ex-Im Lender under the Ex-Im Subfacility Credit Agreement and such participating/transferring Lender’s interest as an Ex-Im Lender under the Ex-Im Subfacility Credit Agreement in the Ex-Im Revolving Advances (and in its “Participation Commitment” (as defined in the Ex-Im Subfacility Credit Agreement) with respect to Ex-Im Swing Loans and Ex-Im Letters of Credit) such that, after giving effect to all such participations, sales, assignments or transfers (as applicable), such Participant, Purchasing Lender or Purchasing CLO (as applicable) shall hold an equal percentage interest (as a participant or a lender, as applicable) in both such selling Lender’s Revolving Commitment and interests in the Revolving Advances (and Participation Commitment with respect to Swing Loans and Letters of Credit) and such selling Lender’s Ex-Im Revolving Commitment as an Ex-Im Lender under the Ex-Im Subfacility Credit Agreement and interests as an Ex-Im Lender under the Ex-Im Subfacility Credit Agreement in the Ex-Im Revolving Advances (and “Participation Commitment” (as defined in the Ex-Im Subfacility Credit Agreement) with respect to Ex-Im Swing Loans and Ex-Im Letters of Credit).

16.4Application of Payments. Agent shall have the continuing and exclusive right to apply or reverse and re-apply any payment and any and all proceeds of Collateral to any portion of the Obligations. To the extent that any Loan Party makes a payment or Agent or any Lender receives any payment or proceeds of the Collateral for any Loan Party’s benefit, which are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver, custodian or any other party under any bankruptcy law, common law or equitable cause, then, to such extent, the Obligations or part thereof intended to be satisfied shall be revived and continue as if such payment or proceeds had not been received by Agent or such Lender.

16.5Indemnity. Each Loan Party shall defend, protect, indemnify, pay and save harmless Agent, Issuer, each Lender and each of their respective officers, directors, Affiliates, attorneys, employees and agents (each an “Indemnified Party”) for and from and against any and all claims, demands, liabilities, obligations, losses, damages, penalties, fines, actions, judgments, suits, costs, charges, expenses and disbursements of any kind or nature whatsoever (including fees and disbursements of outside counsel) (collectively, “Claims”) which may be imposed on, incurred by, or asserted against any Indemnified Party in arising out of or in any way relating to or as a consequence, direct or indirect, of: (i) this Agreement, the Other Documents, the Advances and other Obligations and/or the transactions contemplated hereby including the Transactions, (ii) any action or failure to act or action taken only after delay or the satisfaction of any conditions by any Indemnified Party in connection with and/or relating to the negotiation, execution, delivery or

administration of the Agreement and the Other Documents, the credit facilities established hereunder and thereunder and/or the transactions contemplated hereby including the Transactions, (iii) any Loan Party’s failure to observe, perform or discharge any of its covenants, obligations, agreements or duties under or breach of any of the representations or warranties made in this Agreement and the Other Documents, (iv) the enforcement of any of the rights and remedies of Agent, Issuer or any Lender under the Agreement and the Other Documents, (v) any threatened or actual imposition of fines or penalties, or disgorgement of benefits, for violation of any Anti-Terrorism Law by any Loan Party or any Affiliate or Subsidiary of any Loan Party, and (vi) any claim, litigation, proceeding or investigation instituted or conducted by any Governmental Body or instrumentality, any Loan Party, any Affiliate or Subsidiary of any Loan Party or any other Person with respect to any aspect of, or any transaction contemplated by, or referred to in, or any matter related to, this Agreement or the Other Documents, whether or not Agent or any Lender is a party thereto. Without limiting the generality of any of the foregoing, each Loan Party shall defend, protect, indemnify, pay and save harmless each Indemnified Party from (x) any Claims which may be imposed on, incurred by, or asserted against any Indemnified Party arising out of or in any way relating to or as a consequence, direct or indirect, of the issuance of any Letter of Credit hereunder and (y) any Claims which may be imposed on, incurred by, or asserted against any Indemnified Party under any Environmental Laws with respect to or in connection with any Real Property owned or leased by any Company, any Hazardous Discharge, the presence of any Hazardous Materials affecting such Real Property (whether or not the same originates or emerges from such Real Property or any contiguous real estate), including any Claims consisting of or relating to the imposition or assertion of any Lien on any of such Real Property under any Environmental Laws and any loss of value of such Real Property as a result of the foregoing except to the extent such loss, liability, damage and expense is attributable to any Hazardous Discharge resulting from actions on the part of Agent or any Lender. Loan Parties’ obligations under this Section 16.5 shall arise upon the discovery of the presence of any Hazardous Materials at any Real Property owned or leased by any Company, whether or not any federal, state, or local environmental agency has taken or threatened any action in connection with the presence of any Hazardous Materials, in each such case except to the extent that any of the foregoing arises out of the gross negligence or willful misconduct of the Indemnified Party (as determined by a court of competent jurisdiction in a final and non-appealable judgment). Without limiting the generality of the foregoing, this indemnity shall extend to any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements of any kind or nature whatsoever (including fees and disbursements of counsel) asserted against or incurred by any of the Indemnified Parties by any Person under any Environmental Laws or similar laws by reason of any Loan Party’s or any other Person’s failure to comply with laws applicable to solid or hazardous waste materials, including Hazardous Materials and Hazardous Waste, or other Toxic Substances. Additionally, if any taxes (excluding taxes imposed upon or measured solely by the net income of Agent and Lenders, but including any intangibles taxes, stamp tax, recording tax or franchise tax) shall be payable by Agent, Lenders or Loan Parties on account of the execution or delivery of this Agreement, or the execution, delivery, issuance or recording of any of the Other Documents, or the creation or repayment of any of the Obligations hereunder, by reason of any Applicable Law now or hereafter in effect, Loan Parties will pay (or will promptly reimburse Agent and Lenders for payment of) all such taxes, including interest and penalties thereon, and will indemnify and hold the Indemnified Parties harmless from and against all liability in connection therewith.

16.11Consequential Damages. Neither Agent, nor any Lender, nor any agent or attorney for any of them, shall be liable to any Loan Party (or any Affiliate of any Loan Party) for indirect, punitive, exemplary or consequential damages arising from any breach of contract, tort or other wrong relating to the establishment, administration or collection of the Obligations or as a result of any transaction contemplated under this Agreement or any Other Document.

Each Loan Party and each Lender hereby authorizes Agent to make appropriate announcements of the financial arrangement (exclusive of any pricing terms) entered into among Loan Parties, Agent and Lenders, including announcements which are commonly known as tombstones, in such publications and to such selected parties as Agent shall in its sole and absolute discretion deem appropriate.

(a)Each Lender or assignee or participant of a Lender that is not incorporated under the Laws of the United States of America or a state thereof (and is not excepted from the certification requirement contained in Section 313 of the USA PATRIOT Act and the applicable

regulations because it is both (i) an affiliate of a depository institution or foreign bank that maintains a physical presence in the United States or foreign country, and (ii) subject to supervision by a banking authority regulating such affiliated depository institution or foreign bank) shall deliver to Agent the certification, or, if applicable, recertification, certifying that such Lender is not a “shell” and certifying to other matters as required by Section 313 of the USA PATRIOT Act and the applicable regulations: (1) within ten (10) days after the Closing Date, and (2) as such other times as are required under the USA PATRIOT Act.

(b)The USA PATRIOT Act requires all financial institutions to obtain, verify and record certain information that identifies individuals or business entities which open an “account” with such financial institution. Consequently, Agent and each Lender may from time to time request, and each Loan Party shall provide to Agent or such Lender, such Loan Party’s name, address, tax identification number and/or such other identifying information as shall be necessary for Agent or such Lender to comply with the USA PATRIOT Act and any other Anti-Terrorism Law.

(a)Each Loan Party represents and warrants that (i) no Covered Entity is a Sanctioned Person and (ii) no Covered Entity, either in its own right or through any third party, (A) has any of its assets in a Sanctioned Country or in the possession, custody or control of a Sanctioned Person in violation of any Anti-Terrorism Law; (B) does business in or with, or derives any of its income from investments in or transactions with, any Sanctioned Country or Sanctioned Person in violation of any Anti-Terrorism Law; or (C) engages in any dealings or transactions prohibited by any Anti-Terrorism Law.

(b)Each Loan Party covenants and agrees that (i) no Covered Entity will become a Sanctioned Person, (ii) no Covered Entity, either in its own right or through any third party, will (A) have any of its assets in a Sanctioned Country or in the possession, custody or control of a Sanctioned Person in violation of any Anti-Terrorism Law; (B) do business in or with, or derive any of its income from investments in or transactions with, any Sanctioned Country or Sanctioned Person in violation of any Anti-Terrorism Law; (C) engage in any dealings or transactions prohibited by any Anti-Terrorism Law or (D) use the Advances to fund any operations in, finance any investments or activities in, or, make any payments to, a Sanctioned Country or Sanctioned Person in violation of any Anti-Terrorism Law, (iii) the funds used to repay the Obligations will not be derived from any unlawful activity, (iv) each Covered Entity shall comply with all Anti-Terrorism Laws and (v) the Loan Parties shall promptly notify Agent in writing upon any Loan Party obtaining knowledge of the occurrence of a Reportable Compliance Event.

(c)This Section 16.18 shall not be applied (or construed to apply) to, or for the benefit of, any party domiciled in Germany (Inländer) to the extent that the provisions under this section 16.18 would violate or expose such entity or any officer or employee thereof to any liability under any anti-boycott or blocking law, regulation or statute in force from time to time in the Federal Republic of Germany or the European Union and applicable to such entity (including without limitation EU Regulation (EC) 2271/96 and section 7 of the German Foreign Trade Ordinance (Verordnung zur Durchführung des Außenwirtschaftsgesetzes (Außenwirtschafts-verordnung - AWV)).

16.19Acknowledgement and Consent to Bail-In of EEA Financial Institutions. Notwithstanding anything to the contrary in this Agreement or in any Other Document or in any other agreement, arrangement or understanding among any such parties, each party hereto acknowledges that any liability of any EEA Financial Institution arising under this Agreement or any Other Document, to the extent such liability is unsecured, may be subject to the write-down and conversion powers of an EEA Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by:

16.20Currency Indemnity. If, for the purposes of obtaining judgment in any court in any jurisdiction with respect to this Agreement or any Other Document it becomes necessary to convert into the currency of such jurisdiction (the "Judgment Currency") any amount due under this Agreement or under any of the Other Documents in any currency other than the Judgment Currency (the "Currency Due"), then conversion shall be made at the Exchange Rate at which Agent is able, on the relevant date, to purchase the Currency Due with the Judgment Currency prevailing on the Business Day before the day on which judgment is given. In the event that there is a change in the rate of Exchange Rate prevailing between the Business Day before the day on which the judgment is given and the date of receipt by Agent of the amount due, the Borrowers will, on the date of receipt by Agent, pay such additional amounts, if any, or be entitled to receive reimbursement of such amount, if any, as may be necessary to ensure that the amount received by Agent on such date is the amount in the Judgment Currency which when converted at the rate of exchange prevailing on the date of receipt by Agent is the amount then due under this Agreement or such Other Document in the Currency Due. If the amount of the Currency Due which Agent is able to purchase is less than the amount of the Currency Due originally due to it, the Borrowers shall indemnify and save Agent harmless from and against loss or damage arising as a result of such deficiency. The indemnity contained herein shall constitute an obligation separate and independent from the other obligations contained in this Agreement and the Other Documents, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by Agent from time to time and shall continue in full force and effect

notwithstanding any judgment or order for a liquidated sum in respect of an amount due under this Agreement or any of the Other Documents or under any judgment or order.

16.21Sovereign Immunity. To the extent any Loan Party has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether from service or notice, attachment prior to judgment, attachment in aid of execution of a judgment, execution or otherwise), each Loan Party hereby irrevocably waives such immunity in respect of its obligations hereunder and under the Other Documents.

16.22Ex-Im Subfacility. The parties hereto acknowledge and agree that the credit facility under the Ex-Im Subfacility Credit Agreement is a subfacility under this Agreement and is the “Ex-Im Subfacility” under this Agreement. Notwithstanding anything to the contrary in this Agreement or the Ex-Im Subfacility Credit Agreement, in no event shall any Loan Party have any obligations to make duplicate payments, such as mandatory prepayments or the payment of fees, costs and expenses under the Ex-Im Subfacility Credit Agreement and this Agreement. The parties hereto acknowledge and agree, notwithstanding anything to the contrary herein, that (a) (i) any Lien granted by any of the Loan Parties to the Ex-Im Agent, for the benefit of the Ex-Im Secured Parties, in any Export-Related Collateral pursuant to the Ex-Im Subfacility Credit Agreement or any Ex-Im Subfacility Other Documents shall be senior to any Lien granted by any of the Loan Parties to Agent in such Export-Related Collateral, for the benefit of the Secured Parties, pursuant to this Agreement or any Other Documents and (ii) any Lien granted by any of the Loan Parties to Agent in the Export-Related Collateral, for the benefit of the Secured Parties, pursuant to this Agreement or any Other Documents shall be subordinate to any Lien granted by any of the Loan Parties to the Ex-Im Agent, for the benefit of the Ex-Im Secured Parties, in such Export-Related Collateral pursuant to the Ex-Im Subfacility Credit Agreement or any Ex-Im Subfacility Other Documents and (b) (i) any Lien granted by any of the Loan Parties to Agent, for the benefit of the Secured Parties, in any Secondary Collateral pursuant to this Agreement or any Other Documents shall be senior to any Lien granted by any of the Loan Parties to the Ex-Im Agent, for the benefit of the Ex-Im Secured Parties, in such Secondary Collateral pursuant to the Ex-Im Subfacility Credit Agreement or any Ex-Im Subfacility Other Documents and (ii) any Lien granted by any of the Loan Parties to Agent, for the benefit of the Secured Parties, in any Secondary Collateral pursuant to the Ex-Im Subfacility Credit Agreement or any Ex-Im Subfacility Other Documents shall be subordinate to any Lien granted by any of the Loan Parties to Agent, for the benefit of the Secured Parties, in such Second Collateral pursuant to this Agreement or any Other Documents. In addition, the parties hereto acknowledge and agree, notwithstanding anything to the contrary herein, that (x) the Liens granted by any of the Loan Parties to the Ex-Im Agent, for the benefit of the Ex-Im Secured Parties, in any Inventory Collateral pursuant to the Ex-Im Subfacility Credit Agreement or any Ex-Im Subfacility Other Documents and (y) the Liens granted by any of the Loan Parties to Agent, for the benefit of the Secured Parties, in any Inventory Collateral pursuant to this Agreement or any Other Documents shall rank pari passu. Any representation, warranty or covenant in this Agreement or any Other Document made by any Loan Party with respect to the priority of any Lien in the Collateral shall be made subject to the foregoing sentences. The parties acknowledge that any proxy or power or attorney granted to Agent hereunder has also been granted to the Ex-Im Agent, and Agent and Lenders consent thereto. Solely with respect to the Export-Related Collateral, Agent’s rights and remedies (including any proxies and powers of attorney) under this Agreement and the Other Documents shall be subject to the rights and remedies of the Ex-Im Agent and, solely with respect to the Secondary Collateral, the Ex-Im Agent’s rights and

remedies under the Ex-Im Subfacility Credit Agreement (including any proxies and powers of attorney thereunder) shall be subject to the rights and remedies of Agent. Except in the case where an assignment with respect to the Ex-Im Subfacility Credit Agreement and the Ex-Im Subfacility Other Documents has already taken place under Section 16.3(i) of the Ex-Im Subfacility Credit Agreement, in no event may Agent resign as agent under this Agreement, unless Agent has simultaneously resigned under the Ex-Im Subfacility Credit Agreement, the intent being that Agent under this Agreement shall also be the Ex-Im Agent unless an assignment with respect to the Ex-Im Subfacility Credit Agreement and the Ex-Im Subfacility Other Documents has already taken place under Section 16.3(i) of the Ex-Im Subfacility Credit Agreement.

17.1Guaranty and Suretyship Agreement. Each Guarantor hereby guarantees, and becomes surety for, the prompt payment and performance when due (whether at stated maturity, by required prepayment, declaration, demand, by acceleration or otherwise) of (a) all of the Obligations owing by the Loan Parties to the Secured Parties, including all of the costs and expenses and all of the indemnities owing to any Secured Party or other Indemnitee under the provisions of Sections 16.5 and 16.9 hereof, and (b) the costs and expenses of Agent in enforcing the provisions of this Article XVII (all collectively under the foregoing clauses (a) and (b), the “Guaranteed Obligations”). The obligations and liabilities of the Guarantors under this Article XVII are joint and several, and each Guarantor hereby acknowledges and accepts such joint and several liability and further acknowledges and agrees that the joint and several liabilities of Guarantors under the provisions of this Article XVII shall be primary and direct liabilities and not secondary liabilities.

17.2Guaranty of Payment and Not Merely Collection. The provisions of this Article XVII constitute a guaranty of payment and not of collection and no Secured Party shall be required, as a condition of any Guarantor’s liability hereunder, to make any demand upon or to pursue any of their rights against any Loan Parties and/or any of the Collateral (or any other collateral pledged and/or made subject to any Lien by any Person to secure any part of the Guaranteed Obligations), or to pursue any rights which may be available to any Secured Party with respect to any other person who may be liable for the payment of the Guaranteed Obligations and/or any other collateral or security available to any Secured Party therefor.

(a)The provisions of this Article XVII constitute an absolute, unconditional, irrevocable and continuing guaranty and will remain in full force and effect until all of the Guaranteed Obligations have been Paid in Full. The provisions of this Article XVII will remain in full force and effect even if there are no Guaranteed Obligations outstanding at a particular time or from time to time. The provisions of this Article XVII will not be affected (i) by any surrender, exchange, acceptance, compromise or release by any Secured Party of any other party, or any other guaranty or any Collateral or other collateral or security held by it for any of the Guaranteed Obligations, (ii) by any failure of any Secured Party to take any steps to perfect or maintain their Liens or security interest in or to preserve their rights in or to any Collateral or any other security or other collateral for the Guaranteed Obligations or any guaranty, (iii) the illegality of the guaranteed obligations, (iv) any change in the corporate existence or structure of any borrower, (v)

any law, regulation, decree or order of any jurisdiction or any event affecting any term of a guaranteed obligation, or (vi) by any irregularity, unenforceability or invalidity of the Guaranteed Obligations or any part thereof or any security therefor or other guaranty thereof, and the provisions of this Article XVII will not be affected by any other facts, events, occurrences or circumstances (except Payment in Full of the Guaranteed Obligations) that might otherwise give rise to any “guarantor” or “suretyship” defenses to which any Guarantor might otherwise be entitled, all of which such “guarantor” or “suretyship” defenses are hereby waived by each Guarantor. The obligations of each Guarantor hereunder shall not be affected, modified or impaired by any counterclaim, set-off, deduction or defense of any kind, including any such counterclaim, set-off, deduction or defense based upon any claim such Guarantor may have against any Borrower or any Secured Party (or any of their respective Affiliates), or based upon any claim any Borrower or any other guarantor or surety may have against any Secured Party (or any of their respective Affiliates), except the Payment in Full of the Guaranteed Obligations.

(b)Notice of acceptance of the agreement to guaranty provided for under the provisions of this Article XVII, notice of extensions of credit to Loan Parties from time to time, notice of default, diligence, presentment, notice of dishonor, protest, demand for payment, and any defense based upon any Secured Party’s failure to comply with the notice requirements of §§ 9-611, 9-612 and 9-613 of the Uniform Commercial Code are hereby waived to the fullest extent permitted by law. Each Guarantor hereby waives all defenses based on suretyship or impairment of collateral to the fullest extent permitted by law.

(c)Secured Parties may at any time and from time to time, without impairing or releasing, discharging or modifying any Guarantor’s liabilities hereunder and (for purposes of this Article XVII only) without notice to or the consent of any Guarantor: (i) change the manner, place, time or terms of payment or performance of or interest rates or other fees on, or other terms relating to (including the maturity thereof), any of the Guaranteed Obligations; (ii) renew, extend, substitute, modify, amend or alter or refinance, or grant consents or waivers relating to any of the terms and provisions of this Agreement or any of the Other Documents or of the Guaranteed Obligations, or of any other guaranties, or any security for the Obligations or guaranties, (iii) increase (without limit of any kind) or decrease the Guaranteed Obligations (including all loans and extensions of credit thereunder) or modify the terms on which loans and extensions of credit may be made to Loan Parties (including without limitation by making available to Loan Parties under this Agreement and/or any Other Document and as part of the Guaranteed Obligations any new loans, advances or other extensions of credit of any kind, including any such new loans, advances or extension of credit of a new or different type or nature (including any new Cash Management Products and Services of any kind, Foreign Currency Hedges of any kind and/or Interest Rate Hedge of any kind) as compared to the loans, advances and extensions of credit available to Loan Parties hereunder as of the Closing Date); (iv) apply any and all payments by whomever paid or however realized including any proceeds of the Collateral or any other collateral or security, to any Guaranteed Obligations in such order, manner and amount as Agent may determine in its sole discretion in accordance with the terms of this Agreement; (v) settle, compromise or deal with any other Person, including any Borrower or any other guarantor, with respect to the Guaranteed Obligations in such manner as Agent deems appropriate in its sole discretion; (vi) substitute, exchange, subordinate, sell, compromise or release any security or guaranty for the Guaranteed Obligations; or (vii) take such actions and exercise such remedies hereunder as provided herein.

17.4Repayments or Recovery from Secured Parties. If any demand or claim is made at any time upon any Secured Party for the repayment or recovery of any amount received by it in payment or on account of the Guaranteed Obligations (including any such demand or claim made in respect of or arising out of any laws relating to fraudulent transfers, fraudulent conveyances or preferences) and if any Secured Party repays all or any part of such amount by reason of any judgment, decree or order of any court or administrative body in respect of such demand or claim, or by reason of any settlement or compromise of any such demand or claim, the joint and several liability of Guarantors with respect to such portion of the Guaranteed Obligations previously satisfied by the payment of the amount so repaid or recovered shall be reinstated and revived and Guarantors will be and remain jointly and severally liable hereunder for the amount so repaid or recovered to the same extent as if such amount had never been received originally by Agent and/or such Secured Party, as the case may be. The provisions of this Section 17.4 shall survive any release and/or termination of this Agreement (and/or of any Guarantor’s liability under this Article XVII) and will be and remain effective notwithstanding any contrary action which may have been taken by any Guarantor in reliance upon such payment, and any such contrary action so taken will be without prejudice to Secured Parties’ rights hereunder and any such release and/or termination will be deemed to have been conditioned upon such payment having become final and irrevocable.

17.5Enforceability of Obligations. No modification, limitation or discharge of the Guaranteed Obligations arising out of or by virtue of any bankruptcy, reorganization or similar proceeding for relief of debtors under federal or state law with respect to any Borrower or any other guarantor or surety for the Guaranteed Obligations will affect, modify, limit or discharge Guarantors’ liability in any manner whatsoever and the provisions of this Article XVII will remain and continue in full force and effect and will be enforceable against each Guarantor to the same extent and with the same force and effect as if any such proceeding had not been instituted. Each Guarantor hereby waives all rights and benefits which might accrue to it by reason of any such proceeding and will be liable to the full extent hereunder, irrespective of any modification, limitation or discharge of the Guaranteed Obligations that may result from any such proceeding.

(a) Upon the occurrence of any Event of Default under this Agreement: (i) Guarantors shall pay to Agent, immediately upon Agent’s demand therefore (except in the case of any Event of Default under Section 10.7, in which case Guarantors shall pay to Agent immediately, without any demand or notice whatsoever), the full amount of the Guaranteed Obligations; (ii) Agent in its discretion may exercise with respect to any Collateral of any Guarantor or any other collateral or security for the Guaranteed Obligations any one or more of the rights and remedies provided a secured party under the Uniform Commercial Code or any other applicable law or at equity (all of which such rights and remedies are hereby deemed incorporated herein and confirmed and ratified by Guarantors as if expressly set forth and granted and agreed to by Guarantors herein); and/or (iii) Agent in its discretion may exercise from time to time any other rights and remedies available to it or any other Secured Party at law, in equity or otherwise.

(b)The Guarantors jointly and severally agree that, as between the Guarantors and the Secured Parties, the Obligations of Loan Parties under this Agreement and the Other Documents may be declared to be forthwith due and payable as provided in Section 11.1 hereof (and shall be deemed to have become automatically due and payable in the circumstances provided in

Section 11.1) for purposes of this Article XVII (specifically including Section 17.1 hereof), notwithstanding any stay, injunction or other prohibition preventing such declaration (or such obligations from becoming automatically due and payable) as against Loan Parties and that, in the event of such declaration (or such obligations being deemed to have become automatically due and payable), such Obligations (whether or not due and payable by Loan Parties) shall forthwith become due and payable by the Guarantors for purposes of this Article XVII (specifically including Section 17.1 hereof).

(c)Each Guarantor hereby acknowledges that the guarantee provided for under the provisions of this Article XVII constitutes an instrument for the payment of money, and consents and agrees that any Secured Party, at its sole option, in the event of a dispute by such Guarantor in the payment of any moneys due hereunder, shall have the right to bring a motion-action under New York CPLR Section 3213.

17.7Waiver of Subrogation. Until the Guaranteed Obligations are Paid in Full and this Agreement and the Commitments have been terminated, each Guarantor waives in favor of Secured Parties any and all rights which such Guarantor may have to (a) assert any claim against any Borrower or any other Guarantor based on subrogation, restitution, reimbursement or contribution rights with respect to payments made under the provisions of this Article XVII, and (b) any realization on any property of any Borrower or any other Guarantor, including participation in any marshalling of any Borrower’s or any other Guarantor’s assets.

17.8Continuing Guaranty and Suretyship Agreement. The provisions of this Article XVII shall constitute a continuing guaranty and suretyship obligation of each Guarantor with respect to all Guaranteed Obligations from time to time outstanding, arising or incurred, and shall continue in effect, and Secured Parties may continue to act in reliance hereon, until all of the Guaranteed Obligations have been Paid in Full and this Agreement and the Commitments have been terminated (provided that, even after such time, each provision hereof that expressly states it shall survive any such Payment and Full and/or termination shall remain in full force and effect in accordance with the terms of such provision), and until such time, no Guarantor shall have any right to terminate or revoke the provisions of this Article XVII nor any of the guarantee and surety agreements and other covenants and undertakings provided for herein.

17.9General Limitation on Guarantee Obligations. If, in the course of any legal action or proceeding under any applicable law, including any Insolvency Proceedings with respect to any Guarantor, the obligations of any Guarantor under the provisions of this Article XVII would otherwise be held or determined to be void, voidable, invalid or unenforceable, or subordinated to the claims of any other creditors, on account of the amount of its liability under the provisions of this Article XVII, then, notwithstanding any other provision to the contrary, the amount of such liabilities of such Guarantor under the provisions of this Article XVII shall, without any further action by such Guarantor, any Secured Party or any other Person, be automatically limited and reduced to the highest amount (after giving effect to the right of contribution established in Section 17.10 hereof) that is valid and enforceable and not subordinated to the claims of other creditors as determined in such action or proceeding. Absent any such determination in any such legal action or proceeding, the provisions of this Section 17.9 shall in no respect limit the obligations and liabilities of any Guarantor to Secured Parties, and each Guarantor shall remain liable to Secured Parties for the full amount guaranteed by such Guarantor hereunder .

(a)Agent shall be entitled to enforce the Guaranty provided for under this Article XVII (“this Guarantee”) against any German Guarantor without limitation in respect of:

(i)all and any amounts which are owed under the Guaranteed Obligations (other than only under this clause) by such German Guarantor itself or by any of its Subsidiaries that later become Loan Parties; and

(ii)all and any amounts which are owed under the Guaranteed Obligations by (aa) a shareholder of such German Guarantor or (bb) an affiliated company (verbundenes Unternehmen) within the meaning of section 15 of the German Stock Corporation Act (Aktiengesetz) of a shareholder of such German Guarantor (other than such German Guarantor and its Subsidiaries) provided that

(A)such German Guarantor has entered into a domination and/or profit and loss transfer agreement (Beherrschungs- und/oder Gewinnabführungsvertrag) with such shareholder or affiliated company, and

(B)section 30 of the German Act on Companies with Limited Liability (Gesetz betreffend die Gesellschaften mit beschränkter Haftung) as amended from time to time exempts specific distributions (Leistungen) among parties to a domination and/or profit and loss transfer agreement from the prohibition to pay out assets required for the preservation of the registered share capital (Stammkapital).

(b)Agent and Secured Parties shall not be entitled to enforce this Guarantee against a German Guarantor, if and to the extent that:

(i)this Guarantee secures the obligations of an obligor which is (i) a shareholder of such German Guarantor or (ii) an affiliated company within the meaning of section 15 of the German Stock Corporation Act of a shareholder of such German Guarantor (other than a German Guarantor and its Subsidiaries); and

(ii)such German Guarantor has not entered into a domination and/or profit and loss transfer agreement with such shareholder or affiliate and section 30 of the German Act on Companies with Limited Liability as amended from time to time exempts distributions among parties of a domination and/or profit and loss transfer agreement from the prohibition to pay out assets required for the preservation of the registered share capital; and

(iii)the enforcement of this Guarantee would have the effect of (aa) reducing such German Guarantor's net assets (Reinvermögen) (as determined in accordance with subsection 17.10(c), (the "Net Assets") to an amount of less than its registered share capital or, if the Net Assets are already an amount of less than its registered share capital, of causing such amount to be further reduced and (bb) would thereby affect the assets required for the obligatory preservation of such German Guarantor's registered share capital according to section 30 and section 31 of the German Act on Companies with Limited Liability (as amended from time to time), provided that the amount of the registered share

capital to be taken into consideration shall be the amount registered in the commercial register as at the date hereof, and any increase of the registered share capital registered after the date of this Agreement shall only be taken into account if such increase has been effected with the prior written consent of Agent.

(c)The Net Assets shall be calculated as an amount equal to the sum of the values of such German Guarantor's assets (consisting of all assets which correspond to the items set forth in section 266 sub-section (2) A, B and C of the German Commercial Code (Handelsgesetzbuch)) less the aggregate amount of such German Guarantor's liabilities (consisting of all liabilities and liability reserves which correspond to the items set forth in section 266 sub-section (3) B, C and D of the German Commercial Code). The Net Assets shall be determined in accordance with the generally accepted accounting principles applicable from time to time in Germany (Grundsätze ordnungsgemäßer Buchführung) and be based on the same principles which were applied by such German Guarantor in the preparation of its (at the time in question) most recent annual balance sheet (Jahresbilanz).

(d)The German Guarantor shall, to the extent that such German Guarantor is legally permitted to do so, take measures (including, without limitation, setting-off claims or dissolution of hidden reserves) to increase the amount of Net Assets and, in particular, the German Guarantor shall realise, to the extent legally permitted, any and all of its assets that are not required for the German Guarantor's business (nicht betriebsnotwendig) and where the book value (Buchwert) of such asset or assets shown in the most recent annual balance sheet is significantly lower than the market value of the asset or assets, within a time period reasonably required in order to realise any such asset or assets.

(e)The limitations of this Guarantee set out above shall only apply if such German Guarantor delivers to Agent, without undue delay,

(i)but no later than within 10 Business Days after receipt of a request for payment under this Guarantee by Agent, a notice in writing specifying

(B)the amounts which would, if this Guarantee was enforced, have the effect of (aa) reducing such German Guarantor's Net Assets to an amount of less than its registered share capital or, if the Net Assets are already an amount of less than its registered share capital, of causing such amount to be further reduced and (bb) would thereby affect the assets required for the obligatory preservation of such German Guarantor's registered share capital according to section 30 of the German Act on Companies with Limited Liability (as amended from time to time),

(ii)providing with such notice sufficient supporting evidence, including, without limitation, an up-to-date pro forma balance sheet and a reasonably detailed calculation of the Net Assets (the "Management Determination");

(iii)but not later than within 30 Business Days after receipt of a request for payment under this Guarantee by Agent, an up-to-date balance sheet prepared by a firm of auditors of international standard and reputation which shows the value of such German

Guarantor's Net Assets (the "Balance Sheet"). The Balance Sheet shall be prepared in accordance with the principles set out above and shall contain additional information (in reasonable detail) relating to items to be adjusted pursuant to the above.

(f)If such German Guarantor fails to deliver a Management Determination and/or the Balance Sheet within the aforementioned time periods, Agent shall be entitled to enforce this Guarantee irrespective of the limitations set out herein. For the avoidance of doubt, Agent is entitled to enforce the Guarantee without limitation to the extent enforcement is not restricted based on the Management Determination and the Balance Sheet in any event.

(g)If Agent disagrees with the Management Determination and/or the Balance Sheet, it shall notify such German Guarantor accordingly. Agent shall be entitled to enforce this Guarantee and to apply the proceeds to settle the Guaranteed Obligations without limitation up to the amount which is undisputed between it and such German Guarantor. In relation to the amount which is disputed, Agent shall be entitled to further pursue their claims under this Guarantee if and to the extent that an up-to-date balance sheet prepared by a firm of auditors of international standard and reputation opposing the Balance Sheet (the "Opposing Balance Sheet") shows that the limitations set out herein shall not apply, provided that such other firm of auditors preparing the Opposing Balance Sheet enter into a reliance letter with such German Guarantor. The Opposing Balance Sheet shall be prepared in accordance with the principles set out above.

(h)In relation to any amounts exceeding the amount which according to the Management Determination, the Balance Sheet and, as the case may be, the Opposing Balance Sheet can be enforced in compliance with the limitations set out herein for which such German Guarantor is liable under this Guarantee, Agent shall be entitled to further pursue their claims (if any) after expiry of six (6) months from the date the Balance Sheet was delivered to Agent. However, such German Guarantor is entitled to object that this amount is still necessary for maintaining its registered share capital (calculated as of the date the demand under this Guarantee was made) in accordance with the above.

(i)if and to the extent, despite being in a position to take measures as described above, such German Guarantor fails to take such measures; or

(ii)if a court order providing for the commencement of preliminary insolvency proceedings in respect of the assets of such German Guarantor has been issued.

(j)No reduction of the amount enforceable pursuant to this Guarantee shall prejudice the right of Agent to continue enforcing this Guarantee (subject always to the operation of the limitations set out above at the time of such enforcement) until full satisfaction of the Guaranteed Obligations.

(k)For the avoidance of doubt, nothing shall prevent Agent from enforcing its rights under this Guarantee against such German Guarantor if and to the extent that such enforcement does not contravene the provisions or such limitations are not required in order to protect the managing directors of such German Guarantor from incurring personal liability exposure with

respect to breaches of section 30 of the German Act on Companies with Limited Liability (as amended from time to time and as each interpreted by the German Federal Court).

17.11Right of Contribution. Each Guarantor hereby agrees that to the extent that any Guarantor shall have paid more than its proportionate share of any payment made hereunder, such Guarantor shall be entitled to seek and receive contribution from and against any other Guarantor hereunder which has not paid its proportionate share of such payment. Each Guarantor’s right of contribution shall be subject to the terms and conditions of Section 17.7 hereof. The provisions of this Section 17.10 shall in no respect limit the obligations and liabilities of any Guarantor to Secured Parties, and each Guarantor shall remain liable to Secured Parties for the full amount guaranteed by such Guarantor hereunder.

17.12Keepwell. Without limiting any other provision of this Article XVII or otherwise limiting the provisions of Section 6.15 hereof as to the Loan Parties generally, each Guarantor hereby agrees that, for the purposes of this Article XVII as an absolute, unconditional, irrevocable and continuing guaranty agreement, the provisions of Section 6.15 hereof are hereby incorporated and restated in this Article XVII as an obligation of each Guarantor that is and/or may hereafter be a Qualified ECP Loan Party from time to time.

Each of the parties has signed this Agreement as of the day and year first above written.
