Unless the context of this Agreement otherwise clearly requires, the following rules of construction shall apply to this Agreement and each of the other Loan Documents: (i) references to the plural include the singular, the plural, the part and the whole and the words "include," "includes" and "including" shall be deemed to be followed by the phrase "without limitation"; (ii) the words "hereof," "herein," "hereunder," "hereto" and similar terms in this Agreement or any other Loan Document refer to this Agreement or such other Loan Document as a whole; (iii) article, section, subsection, clause, schedule and exhibit references are to this Agreement or other Loan Document, as the case may be, unless otherwise specified; (iv) reference to any Person includes such Person's successors and assigns; (v) reference to any agreement, including this Agreement and any other Loan Document together with the schedules and exhibits hereto or thereto, document or instrument means such agreement, document or instrument as amended, modified, replaced, substituted for, superseded or restated; (vi) relative to the determination of any period of time, "from" means "from

Subject to the terms and conditions hereof and relying upon the representations and warranties herein set forth, each Bank severally agrees to make Revolving Credit Loans to the Borrower at any time or from time to time on or after the date hereof to the Expiration Date provided that after giving effect to such Loan the aggregate amount of Loans from such Bank shall not exceed such Bank's Revolving Credit Commitment. Within such limits of time and amount and subject to the other provisions of this Agreement, the Borrower may borrow, repay and reborrow pursuant to this Section 2.1.1.

Each Bank shall be obligated to participate in each request for Revolving Credit Loans pursuant to Section 2.5.1 [Revolving Credit Loan Requests] in accordance with its Ratable Share. The aggregate of each Bank's Revolving Credit Loans outstanding hereunder to the Borrower at any time shall never exceed its Revolving Credit Commitment. The obligations of each Bank hereunder are several. The failure of any Bank to perform its obligations hereunder shall not affect the Obligations of the Borrower to any other party nor shall any other party be liable for the failure of such Bank to perform its obligations hereunder. The Banks shall have no obligation to make Revolving Credit Loans hereunder on or after the Expiration Date.

Accruing from the date hereof until the Expiration Date, the Borrower agrees to pay to the Agent for the account of each Bank, as consideration for such Bank's Revolving Credit Commitment hereunder, a nonrefundable commitment fee (the “Commitment Fee”) equal to the Commitment Fee shown as the Pricing Grid attached as Schedule 1.1.1(A) to the Guarantor Credit Agreement as determined from time to time as the Commitment Fee applicable to the Guarantor under the Guarantor Credit Agreement (computed on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed) on the average daily difference between the amount of such Bank's Revolving Credit Commitment as the same may be constituted from time to time and the sum of the Bank’s Revolving Credit Loans outstanding. All Commitment Fees shall be payable in arrears on the first Business Day of each January, April, July and October after the date hereof and on the Expiration Date or upon acceleration of the Notes.

Except as otherwise provided herein, the Borrower may from time to time prior to the Expiration Date request the Banks to make Revolving Credit Loans, or renew the Interest Rate applicable to existing Revolving Credit Loans pursuant to Section 4.2 [Interest Periods], by delivering to the Agent, not later than 10:00 a.m., Pittsburgh time, (i) four (4) Business Days prior to the proposed Borrowing Date with respect to the making of Revolving Credit Loans to which the Euro-Rate applies or the renewal of the Euro-Rate for any Loans; and (ii) four

(4) Business Days prior to either the proposed Borrowing Date with respect to the making of a Revolving Credit Loan to which the Fallback Rate (so long as the conditions requiring such Fallback Rate to be in effect still exist at such time) applies of a duly completed request therefor substantially in the form of Exhibit 2.5.1 or a request by telephone immediately confirmed in writing by letter, facsimile or telex in such form (each, a “Loan Request”), it being understood that the Agent may rely on the authority of any individual making such a telephonic request without the necessity of receipt of such written confirmation. Each Loan Request shall be irrevocable and shall specify (i) the proposed Borrowing Date; (ii) the aggregate amount of the proposed Loans comprising each Borrowing Tranche, which shall be in integral multiples of Yen 50,000,000 and not less than Yen 50,000,000 for each Borrowing Tranche; and (iii) an appropriate Interest Period for the Loans comprising such Borrowing Tranche. It is acknowledged and agreed that the principal amount of Yen 300,000,000 outstanding under the Existing Credit Facility as of the Closing Date shall be deemed for all purposes to be an outstanding Revolving Credit Loan under this Agreement effective as of the Closing Date. Interest outstanding with respect to such amounts as of the Closing Date shall be paid by Borrower as agreed by Borrower and the Bank, but in no case later than March 23, 2012.

The Agent shall, promptly after receipt by it of a Loan Request pursuant to Section 2.5.1 [Revolving Credit Loan Requests], notify the Banks of its receipt of such Loan Request specifying: (i) the proposed Borrowing Date and the time and method of disbursement of the Revolving Credit Loans requested thereby; (ii) the amount of each such Revolving Credit Loan and the applicable Interest Period (which, absent such election, shall be conclusively deemed to be thirty (30) days); and (iii) the apportionment among the Banks of such Revolving Credit Loans as determined by the Agent in accordance with Section 2.2 [Nature of Banks' Obligations]. Each Bank shall remit the principal amount of each Revolving Credit Loan to the Agent such that the Agent is able to, and the Agent shall, to the extent the Banks have made funds available to it for such purpose and subject to Section 7.2 [Each Additional Loan], fund such Revolving Credit Loans to the Borrower in U.S. Dollars and immediately available funds at the Principal Office prior to 2:00 p.m., Pittsburgh time, on the applicable Borrowing Date, provided that if any Bank fails to remit such funds to the Agent in a timely manner, the Agent may elect in its sole discretion to fund with its own funds the Revolving Credit Loans of such Bank on such Borrowing Date, and such Bank shall be subject to the repayment obligation in Section 10.16 [Availability of Funds].

The Obligation of the Borrower to repay the aggregate unpaid principal amount of the Revolving Credit Loans made to it by each Bank, together with interest thereon, shall be evidenced by a Revolving Credit Note dated the Closing Date payable to the order of such Bank in a face amount equal to the Revolving Credit Commitment of such Bank.

The proceeds of the Revolving Credit Loans shall be used (i) to refinance existing indebtedness of the Borrower under the Existing Credit Facility, (ii) to pay fees and expenses associated with the Credit Facilities, and (iii) for general corporate purposes, working capital and Permitted Acquisitions and in accordance with Section 8.1.10 [Use of Proceeds].

The Borrower shall have the right at any time and from time to time upon five (5) Business Days' prior written notice to the Agent to permanently reduce, in whole multiples of Yen 100,000,000 of principal, or terminate the Revolving Credit Commitment without penalty or premium, except as hereinafter set forth, provided

that any such reduction or termination shall be accompanied by prepayment of the Revolving Credit Notes, together with the full amount of interest accrued on the principal sum to be prepaid (and all amounts referred to in Section 5.6 hereof), to the extent that the aggregate amount thereof then outstanding exceeds the Revolving Credit Commitment as so reduced or terminated.

The Borrower shall pay interest in respect of the outstanding unpaid principal amount of the Loans under the Euro-Rate set forth below applicable to the Loans, it being understood that, subject to the provisions of this Agreement, the Borrower may select different Interest Periods to apply simultaneously to the Loans comprising different Borrowing Tranches and may renew one or more Euro-Rate periods with respect to all or any portion of the Loans comprising any Borrowing Tranche, provided that there shall not be at any one time outstanding more than six (6) Borrowing Tranches in the aggregate among all of the Loans. If at any time the designated rate applicable to any Loan made by any Bank exceeds such Bank's highest lawful rate, the rate of interest on such Bank's Loan shall be limited to such Bank's highest lawful rate.

(i)Revolving Credit Euro-Rate: A rate per annum (computed on the basis of a year of 360 days and actual days elapsed) equal to the Euro-Rate plus the Applicable Margin.

The Borrower may call the Agent on or before the date on which a Loan Request is to be delivered to receive an indication of the rates then in effect, but it is acknowledged that such projection shall not be binding on the Agent or the Banks nor affect the rate of interest which thereafter is actually in effect when the election is made.

At any time when the Borrower shall select or renew a Euro-Rate period, the Borrower shall notify the Agent thereof at least four (4) Business Days prior to the effective date of such selection or renewal by delivering a Loan Request. The notice shall specify an Interest Period during which such Loan or renewal shall apply. Notwithstanding the preceding sentence, the following provisions shall apply to any selection of or renewal of a Euro-Rate:

Each Borrowing Tranche of Euro-Rate Loans shall be in integral multiples of Yen 50,000,000 and not less than Yen 50,000,000;

In the case of the renewal of a Euro-Rate at the end of an Interest Period, the first day of the new Interest Period shall be the last day of the preceding Interest Period, without duplication in payment of interest for such day.

To the extent permitted by Law, upon the occurrence of an Event of Default and until such time such Event of Default shall have been cured or waived:

Section 4.1 [Interest Rates], respectively, shall be increased by 2.00% per annum; and

Each other Obligation hereunder if not paid when due shall bear interest at a rate per annum equal to the sum of the rate of interest applicable under the Fallback Rate plus an additional 2.00% per annum from the time such Obligation becomes due and payable and until it is paid in full.

The Borrower acknowledges that the increase in rates referred to in this Section 4.3 reflects, among other things, the fact that such Loans or other amounts have become a substantially greater risk given their default status and that the Banks are entitled to additional compensation for such risk; and all such interest shall be payable by Borrower upon demand by Agent.

If on any date on which a Euro-Rate would otherwise be determined, the Agent shall have determined that:

(i)adequate and reasonable means do not exist for ascertaining such Euro-Rate, or

(ii)a contingency has occurred which materially and adversely affects the London interbank Yen market relating to the Euro-Rate, the Agent shall have the rights specified in Section 4.4.3.

(i)the making, maintenance or funding of any Loan to which a Euro-Rate applies has been made impracticable or unlawful by compliance by such Bank in good faith with any Law or any interpretation or application thereof by any Official Body or with any request or directive of any such Official Body (whether or not having the force of Law), or

(ii)such Euro-Rate will not adequately and fairly reflect the cost to such Bank of the establishment or maintenance of any such Loan, or

(iii)after making all reasonable efforts, deposits of the relevant amount in Dollars for the relevant Interest Period for a Loan, or to banks generally, to which a Euro-Rate applies, respectively, are not available to such Bank with respect to such Loan, or to banks generally, in the interbank eurodollar market, then the Agent shall have the rights specified in Section 4.4.3.

In the case of any event specified in Section 4.4.1 above, the Agent shall promptly so notify the Banks and the Borrower thereof, and in the case of an event specified in Section 4.4.2 above, such Bank shall promptly so notify the Agent and endorse a certificate to such notice as to the specific circumstances of such notice, and the Agent shall promptly send copies of such notice and certificate to the other Banks and the Borrower. Upon such date as shall be specified in such notice (which shall not be earlier than the date such notice is given), the obligation of (A) the Banks, in the case of such notice given by the Agent, or (B) such Bank, in the case of such notice given by such Bank, to allow the Borrower to select or renew a Euro-Rate shall be suspended until the Agent shall have later notified the Borrower, or such Bank shall have later notified the Agent, of the Agent's or such Bank's, as the case may be, determination that the circumstances giving rise to such previous determination no longer exist. If at any time the Agent makes a determination under Section 4.4.1 and the Borrower has previously notified the Agent of its selection of or renewal of a Euro-Rate and such Interest Rate has not yet gone into effect, such notification shall be deemed to provide for selection of the Fallback Rate with respect to such Loans. If any Bank notifies the Agent of a determination under Section 4.4.2, the Borrower shall, subject to the Borrower's indemnification Obligations under Section 5.8, as to any Loan of the Bank to which a Euro-Rate applies, on the date specified in such notice either convert such Loan to the Fallback Rate with respect to such Loan or prepay such Loan in accordance with Section 5.4 [Voluntary Prepayments]. Absent due notice from the Borrower of conversion or prepayment, such Loan shall automatically be converted to the Fallback Rate upon such specified date.

If the Borrower fails to select a new Interest Period to apply to any Borrowing Tranche of Loans under the Euro-Rate at the expiration of an existing Interest Period applicable to such Borrowing Tranche in accordance with the provisions of Section 4.2 [Interest Periods], the Borrower shall be deemed to have elected the thirty (30) day Euro Rate period commencing upon the last day of the existing Interest Period.

All payments and prepayments to be made in respect of principal, interest or other fees or amounts due from the Borrower hereunder shall be payable prior to 11:00 a.m., Pittsburgh time, on the date when due without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived by the Borrower, and without set-off, counterclaim or other deduction of any nature, and an action therefor shall immediately accrue. Such payments shall be made to the Agent at the Principal Office for the ratable accounts of the Banks with respect to the Revolving Credit Loans in Yen and in immediately available funds, and the Agent shall promptly distribute such amounts to the Banks in immediately available funds, provided that in the event payments are received by 11:00 a.m., Pittsburgh time, by the Agent with respect to the Loans and such payments are not distributed to the Banks on the same day received by the Agent, the Agent shall pay the Banks the Federal Funds Effective Rate with respect to the amount of such payments for each day held by the Agent and not distributed to the Banks. The Agent's and each Bank's statement of account, ledger or other relevant record shall, in the absence of manifest error, be conclusive as the statement of the amount of principal of and interest on the Loans and other amounts owing under this Agreement and shall be deemed an “account stated.”

Each borrowing shall be allocated to each Bank according to its Ratable Share, and each selection of or renewal of any Interest Rate or application of the Fallback Rate and each payment or prepayment by the Borrower with respect to principal, interest or other fees or amounts due from the Borrower hereunder to the Banks with respect to the Loans, shall (except as provided in Section 4.4.3 [Agent's and Bank's Rights] in the case of an event specified in Section 4.4 [Euro-Rate Unascertainable; Etc.], 5.4.2 [Replacement of a Bank] or 5.6 [Increased Costs]) be made in proportion to the applicable Loans outstanding from each Bank and, if no such Loans are then outstanding, in proportion to the Ratable Share of each Bank.

Interest on Loans to which the Euro-Rate applies shall be due and payable on the last day of each Interest Period for those Loans. Interest on mandatory prepayments of principal under Section 5.5 [Mandatory Prepayments] shall be due on the date such mandatory prepayment is due. Interest on the principal amount of each Loan or other monetary Obligation shall be due and payable on demand after such principal amount or other monetary Obligation becomes due and payable (whether on the stated maturity date, upon acceleration or otherwise).

The Borrower shall have the right at its option from time to time to prepay the Loans in whole or part without premium or penalty (except as provided in Section 5.4.2 below or in Section 5.6):

(ii)on the last day of the applicable Interest Period with respect to Loans to which a Euro-Rate applies,

(iii)on the date specified in a notice by any Bank pursuant to Section 4.4 [Euro-Rate Unascertainable, Etc.] with respect to any Loan to which a Euro-Rate applies.

Whenever the Borrower desires to prepay any part of the Loans, it shall provide a prepayment notice to the Agent by 1:00 p.m. at least one (1) Business Day prior to the date of prepayment of Revolving Credit Loans, setting forth the following information:

(x)the date, which shall be a Business Day, on which the proposed prepayment is to be made;

(y)a statement indicating the application of the prepayment among the Revolving Credit Loans; and

(z)the total principal amount of such prepayment, which shall not be less than Yen 50,000,000 for any Revolving Credit Loan.

All prepayment notices shall be irrevocable. The principal amount of the Loans for which a prepayment notice is given, together with interest on such principal amount except with respect to Loans to which the Fallback Rate applies, shall be due and payable on the date specified in such prepayment notice as the date on which the proposed prepayment is to be made. Except as provided in Section 4.4.3 [Agent's and Bank's rights], if the Borrower prepays a Loan but fails to specify the applicable Borrowing Tranche which the Borrower is prepaying, the prepayment shall be applied (i) first to Revolving Credit Loans and (ii) after giving effect to the allocations in clause (i) above first to Loans to which the Fallback Rate applies, then to Loans to which the Euro-Rate applies. Any prepayment hereunder shall be subject to the Borrower's Obligation to indemnify the Banks under Section 5.8 [Indemnity].

In the event any Bank (i) gives notice under Section 4.4 [Euro-Rate Unascertainable, Etc.] or Section 5.6, (ii) does not fund Revolving Credit Loans because the making of such Loans would contravene any Law applicable to such Bank, or (iii) becomes subject to the control of an Official Body (other than normal and customary supervision), then the Borrower shall have the right at its option, with the consent of the Agent, which shall not be unreasonably withheld, to prepay the Loans of such Bank in whole, together with all interest accrued

thereon, and terminate such Bank's Commitment within ninety (90) days after (x) receipt of such Bank's notice under Section 4.4 [Euro-Rate Unascertainable, Etc.] or 5.6, (y) the date such Bank has failed to fund Revolving Credit Loans because the making of such Loans would contravene Law applicable to such Bank, or (z) the date such Bank became subject to the control of an Official Body, as applicable; provided that the Borrower shall also pay to such Bank at the time of such prepayment any amounts required under Section 5.6 and any accrued interest due on such amount and any related fees; provided, however, that the Commitment of such Bank shall be provided by one or more of the remaining Banks or a replacement bank acceptable to the Agent; provided, further, the remaining Banks shall have no obligation hereunder to increase their Commitments. Notwithstanding the foregoing, the Agent may only be replaced subject to the requirements of Section 10.14 [Successor Agent].

Each Bank agrees that upon the occurrence of any event giving rise to increased costs or other special payments under Section 4.4.2 [Illegality, Etc.] or 5.6 with respect to such Bank, it will if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Bank) to designate another lending office for any Loans affected by such event, provided that such designation is made on such terms that such Bank and its lending office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of such Section. Nothing in this Section 5.4.3 shall affect or postpone any of the Obligations of the Borrower or any other Loan Party or the rights of the Agent or any Bank provided in this Agreement.

(i)impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Bank (except any reserve requirement reflected in the Euro-Rate);

(ii)subjects any Bank to any tax or changes the basis of taxation with respect to this Agreement, the Notes, the Loans or payments by the Borrower of principal, interest or other amounts due from the Borrower hereunder or under the Notes (except for taxes on the overall net income of such Bank); or

(iii)impose on any Bank or the London interbank market any other condition, cost or expense affecting this Agreement or any Loan under the Euro-Rate made by such;

and the result of any of the foregoing shall be to increase the cost to such Bank of making or maintaining any Loan under the Euro-Rate (or of maintaining its obligation to make any such Loan), or to reduce the amount of any sum received or receivable by such Bank hereunder (whether of principal, interest or any other amount) then, upon request of such Bank, the Borrower will pay to such Bank such additional amount or amounts as will compensate such Bank, for such additional costs incurred or reduction suffered.

If any Bank determines that any Change in Law affecting such Bank or any lending office of such Bank or such Bank's holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on such Bank's capital or on the capital of such Bank's holding company, if any, as a consequence of this Agreement, the Commitments of such Bank or the Loans made by, such Bank, to a level below that which such Bank or such Bank's holding company could have achieved but for such Change in Law (taking into consideration such Bank's policies and the policies of such Bank's holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Bank, such additional amount or amounts as will compensate such Bank or such Bank's holding company for any such reduction suffered.

5.6.3Certificates for Reimbursement; Repayment of Outstanding Loans; Borrowing of New Loans. A certificate of a Bank setting forth the amount or amounts necessary to compensate such Bank or its holding company, as the case may be, as specified in Section 5.6.1 [Increased Costs Generally] or 5.6.2 [Capital Requirements] and setting forth in reasonable detail the calculations necessary to determine such amount or amounts, and delivered to the Borrower shall be conclusive absent manifest error. The Borrower shall pay such Bank the amount shown as due on any such certificate within ten (10) days after receipt thereof.

5.6.4Delay in Requests. Failure or delay on the part of any Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Bank's right to demand such compensation, provided that the Borrower shall not be required to compensate a Bank pursuant to this Section for any increased costs incurred or reductions suffered more than six (6) months prior to the date that such Bank notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Bank's intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the six (6) month period referred to above shall be extended to include the period of retroactive effect thereof).

5.8Indemnity. In addition to the compensation or payments required by Section 5.6, the Borrower shall indemnify each Bank against all liabilities, losses or expenses (including loss of anticipated profits, any foreign exchange losses and any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Loan, from fees payable to terminate the deposits from which such funds were obtained or from the performance of any foreign exchange contract) which such Bank sustains or incurs as a consequence of any:

(i)payment, prepayment, or renewal of any Loan to which a Euro-Rate applies on a day other than the last day of the corresponding Interest Period (whether or not such payment or prepayment is mandatory, voluntary or automatic and whether or not such payment or prepayment is then due),

(ii)attempt by Borrower to revoke (expressly, by later inconsistent notices or otherwise) in whole or part any Loan Requests under Section 2.5 [Revolving Credit Loan Requests] or Section 4.2 [Interest Periods] or notice relating to prepayments under Section 5.4 [Voluntary Prepayments], or

(iii)default by Borrower in the performance or observance of any covenant or condition contained in this Agreement or any other Loan Document, including any failure of the Borrower to pay when due (by acceleration or otherwise) any principal, interest or any other amount due hereunder.

If any Bank sustains or incurs any such loss or expense, it shall from time to time notify the Borrower of the amount determined in good faith by such Bank (which determination may include such assumptions, allocations of costs and expenses and averaging or attribution methods as such Bank shall deem reasonable) to be necessary to indemnify such Bank for such loss or expense. Such notice shall set forth in reasonable detail the basis for such determination. Such amount shall be due and payable by the Borrower to such Bank ten (10) Business Days after such notice is given.

The Loan Parties, jointly and severally, represent and warrant to the Agent and each of the Banks as follows:

Borrower is a corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of organization. Borrower has the lawful power to own or lease its properties and to engage in the business it presently conducts or proposes to conduct. Borrower is duly licensed or qualified and in

good standing in each jurisdiction where failure to be so licensed or qualified and in good standing would result in a Material Adverse Effect.

The authorized capital stock of the Borrower consists of 200 shares of common stock, issued and outstanding as of December 31, 2011. All of the outstanding capital stock of the Borrower is owned directly or indirectly by II-VI Incorporated.

Each Loan Party has full power to enter into, execute, deliver and carry out this Agreement and the other Loan Documents to which it is a party, to incur the Indebtedness contemplated by the Loan Documents and to perform its Obligations under the Loan Documents to which it is a party, and all such actions have been duly authorized by all necessary proceedings on its part.

This Agreement has been duly and validly executed and delivered by each Loan Party, and each other Loan Document which such Loan Party is required to execute and deliver on or after the date hereof will have been duly executed and delivered by such Loan Party on the required date of delivery of such Loan Document. This Agreement and each other Loan Document constitutes, or will constitute, legal, valid and binding obligations of each Loan Party which is or will be a party thereto on and after its date of delivery thereof, enforceable against such Loan Party in accordance with its terms, except to the extent that enforceability of any of such Loan Document may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforceability of creditors' rights generally or limiting the right of specific performance.

Neither the execution and delivery of this Agreement or the other Loan Documents by Borrower nor the consummation of the transactions herein or therein contemplated or compliance with the terms and provisions hereof or thereof by it will conflict with, constitute a default under or result in any breach of (i) the terms and conditions of the certificate of incorporation, bylaws, certificate of limited partnership, partnership agreement, certificate of formation, limited liability company agreement or other organizational documents of Borrower or (ii) to the knowledge of the Loan Parties, any Law having a Material Adverse Effect or any material agreement or instrument or order, writ, judgment, injunction or decree to which Borrower or any of its Subsidiaries is a party or by which it or any of its Subsidiaries is bound or to which it is subject, or result in the creation or enforcement of any Lien, charge or encumbrance whatsoever upon any property (now or hereafter acquired) of Borrower (other than Liens granted under the Loan Documents), except those which will not result in a Material Adverse Effect.

There are no actions, suits, proceedings or investigations pending or, to the knowledge of Borrower, threatened against Borrower or any Subsidiary of Borrower at law or equity before any Official Body which individually or in the aggregate may result in any Material Adverse Change. None of the Borrower or any Subsidiaries of Borrower is in violation of any order, writ, injunction or any decree of any Official Body which may result in any Material Adverse Change.

Borrower has good and marketable title to or valid leasehold interest in all properties, assets and other rights which it purports to own or lease or which are reflected as owned or leased on its books and records and subject to the terms and conditions of the applicable leases. All leases of property are in full force and

effect without the necessity for any consent which has not previously been obtained upon consummation of the transactions contemplated hereby.

The Loan Parties intend to use the proceeds of the Loans in accordance with Sections 2.8 and 8.1.10. None of the Borrower or any Subsidiaries of Borrower engages or intends to engage principally, or as one of its important activities, in the business of extending credit for the purpose, immediately, incidentally or ultimately, of purchasing or carrying margin stock (within the meaning of Regulation U). No part of the proceeds of any Loan has been or will be used, immediately, incidentally or ultimately, to purchase or carry any margin stock or to extend credit to others for the purpose of purchasing or carrying any margin stock or to refund Indebtedness originally incurred for such purpose, or for any purpose which entails a violation of or which is inconsistent with the provisions of the regulations of the Board of Governors of the Federal Reserve System. None of the Borrower or any Subsidiary of Borrower holds or intends to hold margin stock in such amounts that more than 25% of the reasonable value of the assets of Borrower or Subsidiary of Borrower are or will be represented by margin stock.

Neither this Agreement nor any other Loan Document, nor any certificate, statement, agreement or other documents furnished to the Agent or any Bank in connection herewith or therewith, contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained herein and therein, in light of the circumstances under which they were made, not misleading. There is no fact known to Borrower which has a Material Adverse Effect on the business, property, assets, financial condition, results of operations or prospects of Borrower or Subsidiary of Borrower which has not been set forth in this Agreement or in the certificates, statements, agreements or other documents furnished by the Borrower in writing to the Agent and the Banks prior to or at the date hereof in connection with the transactions contemplated hereby.

All federal, state, local and other tax returns required to have been filed with respect to the Borrower and each Subsidiary of each Loan Party have been filed, and payment or adequate provision has been made for the payment of all taxes, fees, assessments and other governmental charges which have or may become due pursuant to said returns or to assessments received, except to the extent that such taxes, fees, assessments and other charges are being contested in good faith by appropriate proceedings diligently conducted and for which such reserves or other appropriate provisions, if any, as shall be required by GAAP shall have been made or do not result in a Material Adverse Change. There are no agreements or waivers extending the statutory period of limitations applicable to any federal income tax return of Borrower or Subsidiary of Borrower for any period.

To the knowledge of the Loan Parties, no consent, approval, exemption, order or authorization of, or a registration or filing with, any Official Body or any other Person is required by any Law or any agreement in connection with the execution, delivery and carrying out of this Agreement and the other Loan Documents by Borrower, except as listed on Schedule 6.1.13, all of which shall have been obtained or made on or prior to the Closing Date except as otherwise indicated on Schedule 6.1.13.

No event has occurred and is continuing and no condition exists or will exist after giving effect to the borrowings or other extensions of credit to be made on the Closing Date under or pursuant to the Loan Documents which constitutes an Event of Default or Potential Default. None of the Loan Parties, or to the Loan

Parties’ knowledge, any Subsidiary of Borrower which is not itself a Loan Party is in violation of (i) any term of its certificate of incorporation, bylaws, certificate of limited partnership, partnership agreement, certificate of formation, limited liability company agreement or other organizational documents or (ii) any material agreement or instrument to which it is a party or by which it or any of its properties may be subject or bound where such violation would constitute a Material Adverse Change.

Borrower and each Subsidiary of Borrower owns or possesses all the material patents, trademarks, service marks, trade names, copyrights, licenses, registrations, franchises, permits and rights necessary to own and operate its properties and to carry on its business as presently conducted and planned to be conducted by Borrower or any Subsidiary, without known possible, alleged or actual conflict with the rights of others, except where the failure to satisfy this representation would not result in a Material Adverse Change.

All material insurance policies to which Borrower or any Subsidiary of Borrower is a party, are valid and in full force and effect, no notice has been given or claim made and no grounds exist to cancel or avoid any of such policies or bonds or to reduce the coverage provided thereby, and such policies and bonds provide adequate coverage from reputable and financially sound insurers in amounts sufficient to insure the assets and risks of Borrower and each Subsidiary of Borrower in accordance with prudent business practice in the industry of the Borrower and its Subsidiaries.

To the knowledge of the Loan Parties, Borrower and each Subsidiary of Borrower are in compliance in all material respects with all applicable Laws in all jurisdictions in which Borrower or Subsidiary of Borrower is presently or will be doing business except where the failure to do so would not constitute a Material Adverse Change.

Should any of the information or disclosures provided on any of the Schedules attached hereto become outdated or incorrect in any material respect, the Borrower shall promptly provide the Agent in writing with such revisions or updates to such Schedule as may be necessary or appropriate to update or correct same; provided, however, that no Schedule shall be deemed to have been amended, modified or superseded by any such correction or update, nor shall any breach of warranty or representation resulting from the inaccuracy or incompleteness of any such Schedule be deemed to have been cured thereby, unless and until the Required Banks, in their sole and absolute discretion, shall have accepted in writing such revisions or updates to such Schedule.

Each Loan Party shall, and Borrower shall cause each of its Subsidiaries to, maintain its legal existence as a corporation, limited partnership or limited liability company and its license or qualification and good standing in each jurisdiction in which its ownership or lease of property or the nature of its business makes such license or qualification necessary, except as otherwise expressly permitted in Section 8.2.6 [Liquidations, Mergers, Etc.] or where the failure to be so licensed or qualified and in good standing would not constitute a Material Adverse Change.

Borrower shall and Borrower shall cause each of its Subsidiaries to, duly pay and discharge all liabilities to which it is subject or which are asserted against it, promptly as and when the same shall become due and payable, including all taxes, assessments and governmental charges upon it or any of its properties, assets, income or profits, prior to the date on which penalties attach thereto, except to the extent that such liabilities, including taxes, assessments or charges, are being contested in good faith and by appropriate and lawful proceedings diligently conducted and for which such reserve or other appropriate provisions, if any, as shall be required by GAAP shall have been made, but only to the extent that failure to discharge any such liabilities would not result in any additional liability which would result in a Material Adverse Change to the financial condition of Borrower or Subsidiary of Borrower or which would result in a Material Adverse Effect on any assets of Borrower, provided that Borrower will pay all such liabilities forthwith upon the commencement of proceedings to foreclose any Lien which may have attached as security therefor.

Borrower shall, and Borrower shall cause each of its Subsidiaries to, insure its properties and assets against loss or damage by fire and such other insurable hazards as such assets are commonly insured (including fire, extended coverage, property damage, workers’ compensation, public liability and business interruption insurance) and against other risks (including errors and omissions) in such amounts as similar properties and assets are insured by prudent companies in similar circumstances carrying on similar businesses, and with reputable and financially sound insurers, including self-insurance to the extent customary, all as reasonably determined by the Agent.

Borrower shall, and Borrower shall cause each of its Subsidiaries to, permit any of the officers or authorized employees or representatives of the Agent or any of the Banks to visit and inspect any of its properties and to examine and make excerpts from its books and records and discuss its business affairs, finances and accounts with its officers, all in such detail and at such times and as often as any of the Banks may reasonably request, provided that each Bank shall provide the Borrower with reasonable notice prior to any visit or inspection. In the event any Bank desires to conduct an audit of Borrower, such Bank shall make a reasonable effort to conduct such audit contemporaneously with any audit to be performed by the Agent, provided that such Bank makes reasonable efforts not to interfere with the ordinary business operations of such Loan Party and that such audit does not interfere with any audit being performed by such Loan Party’s internal or external auditors.

Borrower shall, and Borrower shall cause each of its Subsidiaries to, comply with all applicable Laws, in all respects, provided that it shall not be deemed to be a violation of this Section 8.1.9 if any failure to comply with any Law would not result in fines, penalties, remediation costs, other similar liabilities or injunctive relief which in the aggregate would constitute a Material Adverse Change.

9.2.1.Events of Default Other Than Bankruptcy, Insolvency or Reorganization Proceedings.

If an Event of Default specified under Sections 9.1.1 through 9.1.13 shall occur and be continuing, the Banks and the Agent shall be under no further obligation to make Loans and the Agent may, and

upon the request of the Required Banks, shall by written notice to the Loan Parties, declare the unpaid principal amount of the Notes then outstanding and all interest accrued thereon, any unpaid fees and all other Indebtedness of the Borrower to the Banks hereunder and thereunder to be forthwith due and payable, and the same shall thereupon become and be immediately due and payable to the Agent for the benefit of each Bank without presentment, demand, protest or any other notice of any kind, all of which are hereby expressly waived.

If an Event of Default specified under Section 9.1.14 [Involuntary Proceedings] or 9.1.15 [Voluntary Proceedings] shall occur, the Banks shall be under no further obligations to make Loans hereunder and the unpaid principal amount of the Loans then outstanding and all interest accrued thereon, any unpaid fees and all other Indebtedness of the Borrower to the Banks hereunder and thereunder shall be immediately due and payable, without presentment, demand, protest or notice of any kind, all of which are hereby expressly waived; and

If an Event of Default shall occur and be continuing, any Bank to whom any Obligation is owed by Borrower hereunder or under any other Loan Document or any participant of such Bank which has agreed in writing to be bound by the provisions of Section 10.13 [Equalization of Banks] and any branch, Subsidiary or Affiliate of such Bank or participant anywhere in the world shall have the right, in addition to all other rights and remedies available to it, without notice to such Loan Party, to set-off against and apply to the then unpaid balance of all the Loans and all other Obligations of the Borrower and the other Loan Parties hereunder or under any other Loan Document any debt owing to, and any other funds held in any manner for the account of, the Borrower or such other Loan Party by such Bank or participant or by such branch, Subsidiary or Affiliate, including all funds in all deposit accounts (whether time or demand, general or special, provisionally credited or finally credited, or otherwise) now or hereafter maintained by the Borrower or such other Loan Party for its own account (but not including funds held in custodian or trust accounts) with such Bank or participant or such branch, Subsidiary or Affiliate. Such right shall exist whether or not any Bank or the Agent shall have made any demand under this Agreement or any other Loan Document, whether or not such debt owing to or funds held for the account of the Borrower or such other Loan Party is or are matured or unmatured and regardless of the existence or adequacy of any Guaranty or any other security, right or remedy available to any Bank or the Agent; and

If an Event of Default shall occur and be continuing, and whether or not the Agent shall have accelerated the maturity of Loans pursuant to any of the foregoing provisions of this Section 9.2, the Agent or any Bank, if owed any amount with respect to the Loans, may proceed to protect and enforce its rights by suit in equity, action at law and/or other appropriate proceeding, whether for the specific performance of any covenant or agreement contained in this Agreement or the other Loan Documents, including as permitted by applicable Law the obtaining of the ex parte appointment of a receiver, and, if such amount shall have become due, by declaration or otherwise, proceed to enforce the payment thereof or any other legal or equitable right of the Agent or such Bank; and

From and after the date on which the Agent has taken any action pursuant to this Section 9.2 and until all Obligations of the Loan Parties have been paid in full, any and all proceeds received by the Agent from any sale or other disposition of any assets of Borrower after entry of judgment, or any part thereof, or the exercise of any other remedy by the Agent, shall be applied as follows:

(i)first, to reimburse the Agent and the Banks for out-of-pocket costs, expenses and disbursements, including reasonable attorneys' and paralegals' fees and legal expenses, incurred by the Agent or the Banks in connection with realizing on such assets or collection of any Obligations of any of the

Loan Parties under any of the Loan Documents, including advances made by the Banks or any one of them or the Agent for the reasonable maintenance, preservation, protection or enforcement of, or realization upon, such assets, including advances for taxes, insurance, repairs and the like and reasonable expenses incurred to sell or otherwise realize on, or prepare for sale or other realization on, any of such assets;

(ii)second, to the repayment of all Obligations then due and unpaid of the Loan Parties to the Banks incurred under this Agreement or any of the other Loan Documents, whether of principal, interest, fees, expenses or otherwise, in such manner as the Agent may determine in its discretion; and

All rights of set off existing under any Loan Document shall secure ratably and on a pari passu basis the Obligations in favor of the Agent and the Banks hereunder. The Agent shall be deemed to serve as the collateral agent (the “Collateral Agent”) and the Banks hereunder, provided that the Collateral Agent shall comply with the instructions and directions of the Agent (or the Banks under this Agreement to the extent that this Agreement or any other Loan Documents empowers the Banks to direct the Agent), as to all matters relating to the proceeds of the exercise of such set off rights.

In addition to all of the rights and remedies contained in this Agreement or in any of the other Loan Documents the Agent shall have all of the rights and remedies available under applicable Law, all of which rights and remedies shall be cumulative and non-exclusive, to the extent permitted by Law. The Agent may, and upon the request of the Required Banks shall, exercise all post-default rights granted to the Agent and the Banks under the Loan Documents or applicable Law.

Each Bank hereby irrevocably designates, appoints and authorizes PNC Bank to act as Agent for such Bank under this Agreement and to execute and deliver or accept on behalf of each of the Banks the other Loan Documents. Each Bank hereby irrevocably authorizes, and each holder of any Note by the acceptance of a Note shall be deemed irrevocably to authorize, the Agent to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and any other instruments and agreements referred to herein, and to exercise such powers and to perform such duties hereunder as are specifically delegated to or required of the Agent by the terms hereof, together with such powers as are reasonably incidental thereto. PNC Bank agrees to act as the Agent on behalf of the Banks to the extent provided in this Agreement.

The Agent may perform any of its duties hereunder by or through agents or employees (provided such delegation does not constitute a relinquishment of its duties as Agent) and, subject to Sections 10.5 [Reimbursement of Agent by Borrower, Etc.] and 10.6, shall be entitled to engage and pay for the advice or services of any attorneys, accountants or other experts concerning all matters pertaining to its duties hereunder and to rely upon any advice so obtained.

The Agent shall have no duties or responsibilities except those expressly set forth in this Agreement and no implied covenants, functions, responsibilities, duties, obligations, or liabilities shall be read into this Agreement or otherwise exist. The duties of the Agent shall be mechanical and administrative in nature; the Agent shall not have by reason of this Agreement a fiduciary or trust relationship in respect of any Bank; and

nothing in this Agreement, expressed or implied, is intended to or shall be so construed as to impose upon the Agent any obligations in respect of this Agreement except as expressly set forth herein. Without limiting the generality of the foregoing, the use of the term “agent” in this Agreement with reference to the Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable Law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties. Each Bank expressly acknowledges (i) that the Agent has not made any representations or warranties to it and that no act by the Agent hereafter taken, including any review of the affairs of any of the Loan Parties, shall be deemed to constitute any representation or warranty by the Agent to any Bank; (ii) that it has made and will continue to make, without reliance upon the Agent, its own independent investigation of the financial condition and affairs and its own appraisal of the creditworthiness of each of the Loan Parties in connection with this Agreement and the making and continuance of the Loans hereunder; and (iii) except as expressly provided herein, that the Agent shall have no duty or responsibility, either initially or on a continuing basis, to provide any Bank with any credit or other information with respect thereto, whether coming into its possession before the making of any Loan or at any time or times thereafter.

The Agent agrees, upon the written request of the Required Banks, to take or refrain from taking any action of the type specified as being within the Agent's rights, powers or discretion herein, provided that the Agent shall not be required to take any action which exposes the Agent to personal liability or which is contrary to this Agreement or any other Loan Document or applicable Law. In the absence of a request by the Required Banks, the Agent shall have authority, in its sole discretion, to take or not to take any such action, unless this Agreement specifically requires the consent of the Required Banks or all of the Banks. Any action taken or failure to act pursuant to such instructions or discretion shall be binding on the Banks, subject to Section 10.6 [Exculpatory Provisions, Etc.]. Subject to the provisions of Section 10.6, no Bank shall have any right of action whatsoever against the Agent as a result of the Agent acting or refraining from acting hereunder in accordance with the instructions of the Required Banks, or in the absence of such instructions, in the absolute discretion of the Agent.

The Borrower unconditionally agrees to pay or reimburse the Agent and hold the Agent harmless against (a) liability for the payment of all reasonable out-of-pocket costs, expenses and disbursements, including fees and expenses of counsel (including the allocated costs of staff counsel), appraisers and environmental consultants, incurred by the Agent (i) in connection with the development, negotiation, preparation, printing, execution, administration, syndication, interpretation and performance of this Agreement and the other Loan Documents, (ii) relating to any requested amendments, waivers or consents pursuant to the provisions hereof, (iii) in connection with the enforcement of this Agreement or any other Loan Document or collection of amounts due hereunder or thereunder or the proof and allowability of any claim arising under this Agreement or any other Loan Document, whether in bankruptcy or receivership proceedings or otherwise, and (iv) in any workout or restructuring or in connection with the protection, preservation, exercise or enforcement of any of the terms hereof or of any rights hereunder or under any other Loan Document or in connection with any foreclosure, collection or bankruptcy proceedings, and (b) 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 the Agent, in its capacity as such, in any way relating to or arising out of this Agreement or any other Loan Documents or any action taken or omitted by the Agent hereunder or thereunder, provided that the Borrower shall not be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements if the same results from the Agent's gross negligence or willful misconduct, or if the Borrower was not given notice of the subject claim and the opportunity to participate in the defense thereof, at its expense (except that the Borrower shall remain liable to the extent such failure to give notice does not result in a loss to the Borrower), or if the same results from a compromise or settlement agreement entered into without the consent of the Borrower, which shall not be unreasonably withheld. In addition, the Borrower agrees to reimburse and pay all reasonable out-of-pocket expenses of the Agent's regular employees and agents engaged periodically to perform audits of the Loan Parties' books, records and business properties.

Neither the Agent nor any of its directors, officers, employees, agents, attorneys or Affiliates shall (a) be liable to any Bank for any action taken or omitted to be taken by it or them hereunder, or in connection herewith including pursuant to any Loan Document, unless caused by its or their own gross negligence or willful misconduct, (b) be responsible in any manner to any of the Banks for the effectiveness, enforceability, genuineness, validity or the due execution of this Agreement or any other Loan Documents or for any recital, representation, warranty, document, certificate, report or statement herein or made or furnished under or in connection with this Agreement or any other Loan Documents, or (c) be under any obligation to any of the Banks to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions hereof or thereof on the part of the Loan Parties, or the financial condition of the Loan Parties, or the existence or possible existence of any Event of Default or Potential Default. No claim may be made by any of the Loan Parties, any Bank, the Agent or any of their respective Subsidiaries against the Agent, any Bank or any of their respective directors, officers, employees, agents, attorneys or Affiliates, or any of them, for any special, indirect or consequential damages or, to the fullest extent permitted by Law, for any punitive damages in respect of any claim or cause of action (whether based on contract, tort, statutory liability, or any other ground) based on, arising out of or related to any Loan Document or the transactions contemplated hereby or any act, omission or event occurring in connection therewith, including the negotiation, documentation, administration or collection of the Loans, and each of the Loan Parties, (for itself and on behalf of each of its Subsidiaries), the Agent and each Bank hereby waive, release and agree never to sue upon any claim for any such damages, whether such claim now exists or hereafter arises and whether or not it is now known or suspected to exist in its favor. Each Bank agrees that, except for notices, reports and other documents expressly required to be furnished to the Banks by the Agent hereunder or given to the Agent for the account of or with copies for the Banks, the Agent and each of its directors, officers, employees, agents, attorneys or Affiliates shall not have any duty or responsibility to provide any Bank with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of the Loan Parties which may come into the possession of the Agent or any of its directors, officers, employees, agents, attorneys or Affiliates.

Each Bank agrees to reimburse and indemnify the Agent (to the extent not reimbursed by the Borrower and without limiting the Obligation of the Borrower to do so) in proportion to its Ratable Share from and against all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements, including attorneys' fees and disbursements (including the allocated costs of staff counsel), and costs of appraisers and environmental consultants, of any kind or nature whatsoever which may be imposed on, incurred by or asserted against the Agent, in its capacity as such, in any way relating to or arising out of this Agreement or any other Loan Documents or any action taken or omitted by the Agent hereunder or thereunder, provided that no Bank shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements (a) if the same results from the Agent's gross negligence or willful misconduct, or (b) if such Bank was not given notice of the subject claim and the opportunity to participate in the defense thereof, at its expense (except that such Bank shall remain liable to the extent such failure to give notice does not result in a loss to the Bank), or (c) if the same results from a compromise and settlement agreement entered into without the consent of such Bank, which shall not be unreasonably withheld. In addition, each Bank agrees promptly upon demand to reimburse the Agent (to the extent not reimbursed by the Borrower and without limiting the Obligation of the Borrower to do so) in proportion to its Ratable Share for all amounts due and payable by the Borrower to the Agent in connection with the Agent's periodic audit of the Loan Parties' books, records and business properties.

The Agent shall be entitled to rely upon any writing, telegram, telex or teletype message, resolution, notice, consent, certificate, letter, cablegram, statement, order or other document or conversation by telephone or otherwise believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon the advice and opinions of counsel and other professional advisers selected by the Agent. The Agent shall be fully justified in failing or refusing to take any action hereunder unless it shall first be

indemnified to its satisfaction by the Banks against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action.

The Agent shall not be deemed to have knowledge or notice of the occurrence of any Potential Default or Event of Default unless the Agent has received written notice from a Bank or the Borrower referring to this Agreement, describing such Potential Default or Event of Default and stating that such notice is a “notice of default.”

The Agent shall promptly send to each Bank a copy of all notices received from the Borrower pursuant to the provisions of this Agreement or the other Loan Documents promptly upon receipt thereof.

With respect to its Revolving Credit Commitment and the Revolving Credit Loans made by it and any other rights and powers given to it as a Bank hereunder or under any of the other Loan Documents, the Agent shall have the same rights and powers hereunder as any other Bank and may exercise the same as though it were not the Agent, and the term “Bank” and “Banks” shall, unless the context otherwise indicates, include the Agent in its individual capacity. PNC Bank and its Affiliates and each of the Banks and their respective Affiliates may, without liability to account, except as prohibited herein, make loans to, issue letters of credit for the account of, acquire equity interests in, accept deposits from, discount drafts for, act as trustee under indentures of, and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with, the Loan Parties and their Affiliates, in the case of the Agent, as though it were not acting as Agent hereunder and in the case of each Bank, as though such Bank were not a Bank hereunder, in each case without notice to or consent of the other Banks. The Banks acknowledge that, pursuant to such activities, the Agent or its Affiliates may (i) receive information regarding the Loan Parties or any of their Subsidiaries or Affiliates (including information that may be subject to confidentiality obligations in favor of the Loan Parties or such Subsidiary or Affiliate) and acknowledge that the Agent shall be under no obligation to provide such information to them, and (ii) accept fees and other consideration from the Loan Parties for services in connection with this Agreement and otherwise without having to account for the same to the Banks.

The Agent may deem and treat any payee of any Note as the owner thereof for all purposes hereof unless and until written notice of the assignment or transfer thereof shall have been filed with the Agent. Any request, authority or consent of any Person who at the time of making such request or giving such authority or consent is the holder of any Note shall be conclusive and binding on any subsequent holder, transferee or assignee of such Note or of any Note or Notes issued in exchange therefor.

The Banks and the holders of any participations in any Notes agree among themselves that, with respect to all amounts received by any Bank or any such holder for application on any Obligation hereunder or under any Note or under any such participation, whether received by voluntary payment, by realization upon security, by the exercise of the right of set-off or banker's lien, by counterclaim or by any other non-pro rata source, equitable adjustment will be made in the manner stated in the following sentence so that, in effect, all such excess amounts will be shared ratably among the Banks and such holders in proportion to their interests in payments under the Notes, except as otherwise provided in Section 4.4.3 [Agent's and Bank's Rights], 5.4.2 [Replacement of a Bank] or 5.6 [Increased Costs]. The Banks or any such holder receiving any such amount shall purchase for cash from each of the other Banks an interest in such Bank's Loans in such amount as shall result in a ratable participation by the Banks and each such holder in the aggregate unpaid amount under the Notes, provided that if all or any portion of such excess amount is thereafter recovered from the Bank or the holder making such purchase, such purchase shall

be rescinded and the purchase price restored to the extent of such recovery, together with interest or other amounts, if any, required by law (including court order) to be paid by the Bank or the holder making such purchase.

The Agent (i) may resign as Agent or (ii) shall resign if such resignation is requested by the Required Banks (if the Agent is a Bank, the Agent's Loans and its Commitment shall be considered in determining whether the Required Banks have requested such resignation) or required by Section 5.4.2 [Replacement of a Bank], in either case of (i) or (ii) by giving not less than thirty (30) days' prior written notice to the Borrower. If the Agent shall resign under this Agreement, then either (a) the Required Banks shall appoint from among the Banks a successor agent for the Banks, subject to the consent of the Borrower, such consent not to be unreasonably withheld, or (b) if a successor agent shall not be so appointed and approved within the thirty (30) day period following the Agent's notice to the Banks of its resignation, then the Agent shall appoint, with the consent of the Borrower, such consent not to be unreasonably withheld, a successor agent who shall serve as Agent until such time as the Required Banks appoint and the Borrower consents to the appointment of a successor agent. Upon its appointment pursuant to either clause (a) or (b) above, such successor agent shall succeed to the rights, powers and duties of the Agent, 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 or any of the parties to this Agreement. After the resignation of any Agent hereunder, the provisions of this Section 10 shall inure to the benefit of such former Agent and such former Agent shall not by reason of such resignation be deemed to be released from liability for any actions taken or not taken by it while it was an Agent under this Agreement.

The Agent may assume that each Bank has made or will make the proceeds of a Loan available to the Agent unless the Agent shall have been notified by such Bank on or before the later of (1) the close of Business on the Business Day preceding the Borrowing Date with respect to such Loan or two (2) hours before the time on which the Agent actually funds the proceeds of such Loan to the Borrower (whether using its own funds pursuant to this Section 10.16 or using proceeds deposited with the Agent by the Banks and whether such funding occurs before or after the time on which Banks are required to deposit the proceeds of such Loan with the Agent). The Agent may, in reliance upon such assumption (but shall not be required to), make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the Agent by such Bank, the Agent shall be entitled to recover such amount on demand from such Bank (or, if such Bank fails to pay such amount forthwith upon such demand from the Borrower) together with interest thereon, in respect of each day during the period commencing on the date such amount was made available to the Borrower and ending on the date the Agent recovers such amount, at a rate per annum equal to (i) the Federal Funds Effective Rate during the first three (3) days after such interest shall begin to accrue and (ii) the applicable interest rate in respect of such Loan after the end of such three-day period.

In the absence of gross negligence or willful misconduct, the Agent shall not be liable for any error in computing the amount payable to any Bank whether in respect of the Loans, fees or any other amounts due to the Banks under this Agreement. In the event an error in computing any amount payable to any Bank is made, the Agent, the Borrower and each affected Bank shall, forthwith upon discovery of such error, make such adjustments as shall be required to correct such error, and any compensation therefor will be calculated at the Federal Funds Effective Rate.

Each Bank acknowledges and agrees that neither such Bank, nor any of its Affiliates, participants or assignees, may rely on the Agent to carry out such Bank'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 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 the Loan Parties, their Affiliates or their agents, the Loan Documents or the transactions hereunder or contemplated hereby: (1) any identity verification procedures, (2) any recordkeeping, (3) comparisons with government lists, (4) customer notices or (5) other procedures required under the CIP Regulations or such other Laws.

Except as expressly provided herein, the provisions of this Section 10 are solely for the benefit of the Agent and the Banks, and the Loan Parties shall not have any rights to rely on or enforce any of the provisions hereof. In performing its functions and duties under this Agreement, the Agent shall act solely as agent of the Banks and does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for any of the Loan Parties.

With the written consent of the Required Banks, the Agent, acting on behalf of all the Banks, and the Borrower, on behalf of the Loan Parties, may from time to time enter into written agreements amending or changing any provision of this Agreement or any other Loan Document or the rights of the Banks or the Loan Parties hereunder or thereunder, or may grant written waivers or consents to a departure from the due performance of the Obligations of the Loan Parties hereunder or thereunder. Any such agreement, waiver or consent made with such written consent shall be effective to bind all the Banks and the Loan Parties; provided that, without the written consent of all the Banks, no such agreement, waiver or consent may be made which will:

Extend the Expiration Date or increase the amount of the Revolving Credit Commitment of any Bank hereunder;

Whether or not any Loans are outstanding, extend the time for payment of principal or interest of any Loan (excluding the due date of any mandatory prepayment of a Loan or any mandatory Commitment reduction in connection with such a mandatory prepayment hereunder except for mandatory reductions of the Commitments on the Expiration Date) or any other fee payable to any Bank, or reduce the principal amount of or the rate of interest borne by any Loan or reduce any other fee payable to any Bank, or otherwise affect the terms of payment of the principal of or interest of any Loan or any other fee payable to any Bank; or

Amend Section 5.2 [Pro Rata Treatment of Banks], 10.6 [Exculpatory Provisions, Etc.] or 10.13 [Equalization of Banks] or this Section 11.1, alter any provision regarding the pro rata treatment of the Banks, change the definition of Required Banks, or change any requirement providing for the Banks or the Required Banks to authorize the taking of any action hereunder;

provided, further, that no agreement, waiver or consent which would modify the interests, rights or obligations of the Agent in its capacity as Agent shall be effective without the written consent of the Agent.

No course of dealing and no delay or failure of the Agent or any Bank in exercising any right, power, remedy or privilege under this Agreement or any other Loan Document shall affect any other or future exercise thereof or operate as a waiver thereof, nor shall any single or partial exercise thereof or any abandonment or discontinuance of steps to enforce such a right, power, remedy or privilege preclude any further exercise thereof or of any other right, power, remedy or privilege. The rights and remedies of the Agent and the Banks under this Agreement and any other Loan Documents are cumulative and not exclusive of any rights or remedies which they would otherwise have. Any waiver, permit, consent or approval of any kind or character on the part of any Bank of any breach or default under this Agreement or any such waiver of any provision or condition of this Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing.

The Borrower agrees unconditionally upon demand to pay or reimburse to each Bank (other than the Agent, as to which the Borrower's Obligations are set forth in Section 10.5 [Reimbursement of Agent By Borrower, Etc.]) and to save such Bank harmless against (i) liability for the payment of all reasonable out-of-pocket costs, expenses and disbursements (including reasonable fees and expenses of counsel (including allocated costs of staff counsel) for each Bank except with respect to (a) and (b) below), incurred by such Bank (a) in connection with the administration and interpretation of this Agreement, and other instruments and documents to be delivered hereunder, (b) relating to any amendments, waivers or consents pursuant to the provisions hereof, (c) in connection with the enforcement of this Agreement or any other Loan Document, or collection of amounts due hereunder or thereunder or the proof and allowability of any claim arising under this Agreement or any other Loan Document, whether in bankruptcy or receivership proceedings or otherwise, and (d) in any workout or restructuring or in connection with the protection, preservation, exercise or enforcement of any of the terms hereof or of any rights hereunder or under any other Loan Document or in connection with any foreclosure, collection or bankruptcy proceedings, or (ii) 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 such Bank, in its capacity as such, in any way relating to or arising out of this Agreement or any other Loan Documents or any action taken or omitted by such Bank hereunder or thereunder, provided that the Borrower shall not be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements (A) if the same results from such Bank's gross negligence or willful misconduct, or (B) if the Borrower was not given notice of the subject claim and the opportunity to participate in the defense thereof, at its expense (except that the Borrower shall remain liable to the extent such failure to give notice does not result in a loss to the Borrower), or (C) if the same results from a compromise or settlement agreement entered into without the consent of the Borrower, which shall not be unreasonably withheld. The Banks will attempt to minimize the fees and expenses of legal counsel for the Banks which are subject to reimbursement by the Borrower hereunder by considering the usage of one law firm to represent the Banks and the Agent if appropriate under the circumstances. The Borrower agrees unconditionally to pay all stamp, document, transfer, recording or filing taxes or fees and similar impositions now or hereafter determined by the Agent or any Bank to be payable in connection with this Agreement or any other Loan Document, and the Borrower agrees unconditionally to save the Agent and the Banks harmless from and against any and all present or future claims, liabilities or losses with respect to or resulting from any omission to pay or delay in paying any such taxes, fees or impositions.

Whenever payment of a Loan to be made or taken hereunder shall be due on a day which is not a Business Day such payment shall be due on the next Business Day (except as provided in Section 4.2 [Interest Periods] with respect to Interest Periods under the Euro-Rate) and such extension of time shall be included in computing interest and fees, except that the Loans shall be due on the Business Day preceding the Expiration Date if the Expiration Date is not a Business Day. Whenever any payment or action to be made or taken hereunder (other than payment of the Loans) shall be stated to be due on a day which is not a Business Day, such payment or action shall be made or taken on the next following Business Day, and such extension of time shall not be included in computing interest or fees, if any, in connection with such payment or action.

Each Bank shall have the right from time to time, without notice to the Borrower, to deem any branch, Subsidiary or Affiliate (which for the purposes of this Section 11.5 shall mean any corporation or association which is directly or indirectly controlled by or is under direct or indirect common control with any corporation or association which directly or indirectly controls such Bank) of such Bank to have made, maintained or funded any Loan to which the Euro-Rate applies at any time, provided that immediately following (on the assumption that a payment were then due from the Borrower to such other office), and as a result of such change, the Borrower would not be under any greater financial obligation pursuant to Section 5.6 [Increased Costs] than it would have been in the absence of such change. Notional funding offices may be selected by each Bank without regard to such Bank's actual methods of making, maintaining or funding the Loans or any sources of funding actually used by or available to such Bank.

Each Bank shall have the right from time to time to make or maintain any Loan by arranging for a branch, Subsidiary or Affiliate of such Bank to make or maintain such Loan subject to the last sentence of this Section 11.5.2. If any Bank causes a branch, Subsidiary or Affiliate to make or maintain any part of the Loans hereunder, all terms and conditions of this Agreement shall, except where the context clearly requires otherwise, be applicable to such part of the Loans to the same extent as if such Loans were made or maintained by such Bank, but in no event shall any Bank's use of such a branch, Subsidiary or Affiliate to make or maintain any part of the Loans hereunder cause such Bank or such branch, Subsidiary or Affiliate to incur any cost or expenses payable by the Borrower hereunder or require the Borrower to pay any other compensation to any Bank (including any expenses incurred or payable pursuant to Section 5.6[Increased Costs]) which would otherwise not be incurred.

Any notice, request, demand, direction or other communication (for purposes of this Section 11.6 only, a “Notice”) to be given to or made upon any party hereto under any provision of this Agreement shall be given or made by telephone or in writing (which includes means of electronic transmission (i.e., “e-mail”) or facsimile transmission or by setting forth such Notice on a site on the World Wide Web (a “Website Posting”) if Notice of such Website Posting (including the information necessary to access such site) has previously been delivered to the applicable parties hereto by another means set forth in this Section 11.6) in accordance with this Section 11.6. Any such Notice must be delivered to the applicable parties hereto at the addresses and numbers set forth under their respective names on Schedule 1.1(B) hereof or in accordance with any subsequent unrevoked Notice from any such party that is given in accordance with this Section 11.6. Any Notice shall be effective:

(ii) If given by mail, four days after such Notice is deposited with the United States Postal Service, with first-class postage prepaid, return receipt requested;

(iii)In the case of a telephonic Notice, when a party is contacted by telephone, if delivery of such telephonic Notice is confirmed no later than the next Business Day by hand delivery, a facsimile or electronic transmission, a Website Posting or overnight courier delivery of a confirmatory notice (received at or before noon on such next Business Day);

(iv) In the case of a facsimile transmission, when sent to the applicable party's facsimile machine's telephone number if the party sending such Notice receives confirmation of the delivery thereof from its own facsimile machine;

(vi) In the case of a Website Posting, upon delivery of a Notice of such posting (including the information necessary to access such web site) by another means set forth in this Section 11.6; and

(vii)If given by any other means (including by overnight courier), when actually received.

Any Bank giving a Notice to a Loan Party shall concurrently send a copy thereof to the Agent, and the Agent shall promptly notify the other Banks of its receipt of such Notice.

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

This Agreement shall be deemed to be a contract under the Laws of the Commonwealth of Pennsylvania and for all purposes shall be governed by and construed and enforced in accordance with the internal laws of the Commonwealth of Pennsylvania without regard to its conflict of laws principles.

This Agreement and the other Loan Documents supersede all prior understandings and agreements, whether written or oral, between the parties hereto and thereto relating to the transactions provided for herein and therein, including any prior confidentiality agreements and commitments.

All representations and warranties of the Loan Parties contained herein or made in connection herewith shall survive the making of Loans and shall not be waived by the execution and delivery of this Agreement, any investigation by the Agent or the Banks, the making of Loans or payment in full of the Loans. All covenants and agreements of the Loan Parties contained in Sections 8.1 [Affirmative Covenants], 8.2 [Negative Covenants] and 8.3 [Reporting Requirements] herein shall continue in full force and effect from and after the date hereof so long as the Borrower until termination of the Commitments and payment in full of the Loans. All covenants and agreements of the Borrower contained herein relating to the payment of principal, interest, premiums, additional compensation or expenses and indemnification, including those set forth in the Notes, Section 5 [Payments] and Sections 10.5 [Reimbursement of Agent by Borrower, Etc.], 10.7 [Reimbursement of Agent by Banks, Etc.] and 11.3 [Reimbursement of Banks by Borrower; Etc.], shall survive payment in full of the Loans.

(i)This Agreement shall be binding upon and shall inure to the benefit of the Banks, the Agent, the Loan Parties and their respective successors and assigns, except that none of the Loan Parties may assign or transfer any of its rights and Obligations hereunder or any interest herein. Each Bank may, at its own cost, make assignments of or sell participations in all or any part of its Commitments and the Loans made by it to one or more banks or other entities, subject to the consent of the Borrower and the Agent with respect to any assignee, such consent not to be unreasonably withheld, provided that (1) no consent of the Borrower shall be required (A) if an Event of Default exists and is continuing, or (B) in the case of an assignment by a Bank to an Affiliate of such Bank, and (2) any assignment by a Bank to a Person other than an Affiliate of such Bank may not be made in amounts less than the lesser of Yen 50,000,000 or the amount of the assigning Bank's Commitment. In the case of an assignment, upon receipt by the Agent of the Assignment and Assumption Agreement, the assignee shall have, to the extent of such assignment (unless otherwise provided therein), the same rights, benefits and obligations as it would have if it had been a signatory Bank hereunder, the Commitments shall be adjusted

accordingly, and upon surrender of any Note subject to such assignment, the Borrower shall execute and deliver a new Note to the assignee in an amount equal to the amount of the Revolving Credit Commitment assumed by it and a new Revolving Credit Note to the assigning Bank in an amount equal to the Revolving Credit Commitment retained by it hereunder. Any Bank which assigns any or all of its Commitment or Loans to a Person other than an Affiliate of such Bank shall pay to the Agent a service fee in the amount of $3,500 for each assignment. In the case of a participation, the participant shall only have the rights specified in Section 9.2.3 [Set-off] (the participant's rights against such Bank in respect of such participation to be those set forth in the agreement executed by such Bank in favor of the participant relating thereto and not to include any voting rights except with respect to changes of the type referenced in Sections 11.1.1 [Increase of Commitment, Etc.], 11.1.2 [Extension of Payment, Etc.], all of such Bank's obligations under this Agreement or any other Loan Document shall remain unchanged, and all amounts payable by Borrower hereunder or thereunder shall be determined as if such Bank had not sold such participation.

(ii)Any assignee or participant which is not incorporated under the Laws of the United States of America or a state thereof shall deliver to the Borrower and the Agent the form of certificate described in Section 11.17 [Tax Withholding Clause] relating to federal income tax withholding. Each Bank may furnish any publicly available information concerning Borrower or its Subsidiaries and any other information concerning Borrower or its Subsidiaries in the possession of such Bank from time to time to assignees and participants (including prospective assignees or participants), provided that such assignees and participants agree to be bound by the provisions of Section 11.12 [Confidentiality].

(iii)Notwithstanding any other provision in this Agreement, any Bank may at any time pledge or grant a security interest in all or any portion of its rights under this Agreement, its Note and the other Loan Documents to any Federal Reserve Bank in accordance with Regulation A of the FRB or U.S. Treasury Regulation 31 CFR Section 203.14 without notice to or consent of the Borrower or the Agent. No such pledge or grant of a security interest shall release the transferor Bank of its obligations hereunder or under any other Loan Document.

The Agent and the Banks each agree to keep confidential all information obtained from the Loan Parties including the Borrower or its Subsidiaries which is nonpublic and confidential or proprietary in nature (including any information the Loan Parties specifically designates as confidential), except as provided below, and to use such information only in connection with their respective capacities under this Agreement and for the purposes contemplated hereby. The Agent and the Banks shall be permitted to disclose such information (i) to outside legal counsel, accountants and other professional advisors who need to know such information in connection with the administration and enforcement of this Agreement, subject to the agreement of such Persons to maintain confidentiality, (ii) to assignees and participants as contemplated by Section 11.11, and prospective assignees and participants, subject to agreement of such persons to maintain confidentiality (iii) to the extent requested by any bank regulatory authority or, with notice to the Borrower, as otherwise required by applicable Law or by any subpoena or similar legal process, or in connection with any investigation or proceeding arising out of the transactions contemplated by this Agreement, (iv) if it becomes publicly available other than as a result of a breach of this Agreement or becomes available from a source not known to be subject to confidentiality restrictions, or (v) if the Loan Parties shall have consented to such disclosure. Notwithstanding anything herein to the contrary, the information subject to this Section 11.12.1 shall not include, and the Agent and each Bank may disclose without limitation of any kind, any information with respect to the “tax treatment” and “tax structure” (in each case, within the meaning of Treasury Regulation Section 1.6011-4) of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to the Agent or such Bank relating to such tax treatment and tax structure; provided that with respect to any document or similar item that in either case contains information concerning the tax treatment or tax structure of the transaction as well as other information, this sentence shall only apply to such portions of the document or similar item that relate to the tax treatment or tax structure of the Loans and transactions contemplated hereby.

This Agreement may be executed by different parties hereto on any number of separate counterparts, each of which, when so executed and delivered, shall be an original, and all such counterparts shall together constitute one and the same instrument.

Whenever the Agent's or any Bank's consent is required to be obtained under this Agreement or any of the other Loan Documents as a condition to any action, inaction, condition or event, the Agent and each Bank shall be authorized to give or withhold such consent in its sole and absolute discretion and to condition its consent upon the giving of additional collateral, the payment of money or any other matter.

The representations, warranties and covenants contained herein shall be independent of each other, and no exception to any representation, warranty or covenant shall be deemed to be an exception to any other representation, warranty or covenant contained herein unless expressly provided, nor shall any such exceptions be deemed to permit any action or omission that would be in contravention of applicable Law.

EACH LOAN PARTY HEREBY IRREVOCABLY CONSENTS TO THE NONEXCLUSIVE JURISDICTION OF THE COURT OF COMMON PLEAS OF ALLEGHENY COUNTY, PENNSYLVANIA AND THE UNITED STATES DISTRICT COURT FOR THE WESTERN DISTRICT OF PENNSYLVANIA, AND WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND CONSENTS THAT ALL SUCH SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED MAIL DIRECTED TO SUCH LOAN PARTY AT THE ADDRESSES PROVIDED FOR IN SECTION 11.6 AND SERVICE SO MADE SHALL BE DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF. EACH LOAN PARTY WAIVES ANY OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF JURISDICTION OR VENUE. EACH LOAN PARTY, THE AGENT AND THE BANKS HEREBY WAIVE TRIAL BY JURY IN ANY ACTION, SUIT, PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT TO THE FULL EXTENT PERMITTED BY LAW.

Each Bank or assignee or participant of a Bank that is not incorporated under the Laws of the United States of America or a state thereof (and, upon the written request of the Agent, each other Bank or assignee or participant of a Bank) agrees that it will deliver to each of the Loan Parties and the Agent two (2) duly completed appropriate valid Withholding Certificates (as defined under § 1.1441-1(c)(16) of the Income Tax Regulations (the “Regulations”)) certifying its status (i.e. U.S. or foreign person) and, if appropriate, making a claim of reduced, or exemption from, U.S. withholding tax on the basis of an income tax treaty or an exemption provided by the Internal Revenue Code. The term “Withholding Certificate” means a Form W-9; a Form W-8BEN; a Form W-8ECI; a Form W-8IMY and the related statements and certifications as required under § 1.1441-1(e)(2) and/or (3) of the Regulations; a statement described in § 1.871-14(c)(2)(v) of the Regulations; or any other certificates under the Internal Revenue Code or Regulations that certify or establish the status of a payee or beneficial owner as a U.S. or foreign person. Each Bank, assignee or participant required to deliver to the Loan Parties and the Agent a Withholding Certificate pursuant to the preceding sentence shall deliver such valid Withholding Certificate as follows: (A) each Bank which is a party hereto on the Closing Date shall deliver such valid Withholding Certificate at least five (5) Business Days prior to the first date on which any interest or fees are payable by the Loan Parties hereunder for the account of such Bank; (B) each assignee or participant shall deliver such valid Withholding

Certificate at least five (5) Business Days before the effective date of such assignment or participation (unless the Agent in its sole discretion shall permit such assignee or participant to deliver such valid Withholding Certificate less than five (5) Business Days before such date in which case it shall be due on the date specified by the Agent). Each Bank, assignee or participant which so delivers a valid Withholding Certificate further undertakes to deliver to each of the Loan Parties and the Agent two (2) additional copies of such Withholding Certificate (or a successor form) on or before the date that such Withholding Certificate expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent Withholding Certificate so delivered by it, and such amendments thereto or extensions or renewals thereof as may be reasonably requested by the Loan Parties or the Agent. Notwithstanding the submission of a Withholding Certificate claiming a reduced rate of or exemption from U.S. withholding tax, the 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 Regulations. Further, the Agent is indemnified under § 1.1461-1(e) of the Regulations against any claims and demands of any Bank or assignee or participant of a Bank for the amount of any tax it deducts and withholds in accordance with regulations under § 1441 of the Internal Revenue Code.

Each Bank or assignee or participant of a Bank 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 county, and (ii) subject to supervision by a banking authority regulating such affiliated depository institution or foreign bank) shall deliver to the Agent the certification, or, if applicable, recertification, certifying that such Bank 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 10 days after the Closing Date, and (2) as such other times as are required under the USA Patriot Act.

Borrower hereby irrevocably appoints the Borrower Agent as its agent for purposes of requesting and continuing Loans (including all elections of interest rates), for delivering notices as to prepayments, delivery of payments and prepayments, for requesting amendments, for requesting increases or decreases in availability under this Credit Facility, for requesting waivers and consents, for reporting requirement processing, for information request processing and for providing consents pursuant to Section 11.11 [Successors and Assigns]. The Administrative Agent shall be entitled to rely in such matters on all communications delivered by the Borrower Agent as being delivered on behalf of the Borrower.

IN WITNESS WHEREOF, the parties hereto, by their officers thereunto duly authorized, have executed this Agreement as of the day and year first above written.

THIS CONTINUING AGREEMENT OF GUARANTY AND SURETYSHIP (this “Guaranty”), dated as of this 31st day of January, 2012, is jointly and severally given by EACH OF THE UNDERSIGNED AND EACH OF THE OTHER PERSONS WHICH BECOME GUARANTORS HEREUNDER FROM TIME TO TIME (each a “Guarantor” and collectively the “Guarantors”) in favor of PNC BANK, NATIONAL ASSOCIATION, as agent for the Banks (the “Agent”) in connection with that Credit Agreement, dated as of January 31, 2012, by and among II-VI Japan Incorporated, a Pennsylvania corporation (the “Borrower”), the Agent, the Banks now or hereafter party thereto (the “Banks”) and the Guarantors (as amended, restated, modified, or supplemented from time to time hereafter, the “Credit Agreement”). Capitalized terms not otherwise defined herein shall have the respective meanings ascribed to them by the Credit Agreement and the rules of construction set forth in Section 1.2 [Construction] of the Credit Agreement shall apply to this Guaranty.

1.Guarantied Obligations. To induce the Agent and the Banks to make loans and grant other financial accommodations to the Borrower under the Credit Agreement, each Guarantor hereby jointly and severally unconditionally, and irrevocably, guaranties to the Agent, each Bank and becomes surety, as though it was a primary obligor for, the full and punctual payment and performance when due (whether on demand, at stated maturity, by acceleration, or otherwise and including any amounts which would become due but for the operation of an automatic stay under the federal bankruptcy code of the United States or any similar Laws of any country or jurisdiction) of all Obligations, including, without limiting the generality of the foregoing, all obligations, liabilities, and indebtedness from time to time of the Borrower or any other Guarantor to the Agent or any of the Banks or any Affiliate of any Bank under or in connection with the (i) Credit Agreement, (ii) any other Loan Document, (iii) any other obligation of the Borrower to PNC Bank, National Association, whether for principal, interest, fees, indemnities, expenses, or otherwise, and all renewals, extensions, amendments, refinancing or refundings thereof, whether such obligations, liabilities, or indebtedness are direct or indirect, secured or unsecured, joint or several, absolute or contingent, due or to become due, whether for payment or performance, now existing or hereafter arising (and including obligations, liabilities, and indebtedness arising or accruing after the commencement of any bankruptcy, insolvency, reorganization, or similar proceeding with respect to the Borrower or any Guarantor or which would have arisen or accrued but for the commencement of such proceeding, even if the claim for such obligation, liability, or indebtedness is not enforceable or allowable in such proceeding, and including all Obligations, liabilities, and Indebtedness arising from any extensions of credit under or in connection with any Loan Document from time to time, regardless of whether any such extensions of credit are in excess of the amount committed under or contemplated by the Loan Documents or are made in circumstances in which any condition to extension of credit is not satisfied) (all of the foregoing obligations, liabilities and indebtedness are referred to herein collectively as the “Guarantied Obligations” and each as a “Guarantied Obligation”). Without limitation of the foregoing, any of the Guarantied Obligations shall be and remain Guarantied Obligations entitled to the benefit of this Guaranty if the Agent or any of the Banks (or any one or more assignees or transferees thereof) from time to time assign or otherwise transfer all or any portion of their respective rights and obligations under the Loan Documents, or any other Guarantied Obligations, to any other Person. In furtherance of the foregoing, each Guarantor jointly and severally agrees as follows.

2.Guaranty. Each Guarantor hereby promises to pay and perform all such Guarantied Obligations immediately upon demand of the Agent and the Banks or any one or more of them. All payments made hereunder shall be made by each Guarantor in immediately available funds in U.S. Dollars or Japanese Yen, as elected by the Agent, and shall be made without setoff, counterclaim, withholding, or other deduction of any nature.

3.Obligations Absolute. The obligations of the Guarantors hereunder shall not be discharged or impaired or otherwise diminished by the failure, default, omission, or delay, willful or otherwise, by any Bank, the Agent, or any Borrower or any other obligor on any of the Guarantied Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of any Guarantor as a matter of law or equity. Each of the Guarantors agrees that the Guarantied Obligations will be paid and performed strictly in accordance with the terms of the Loan Documents. Without limiting the generality of the foregoing, each Guarantor hereby consents to, at any time and from time to time, and, the joint and several obligations of each Guarantor hereunder shall not be diminished, terminated, or otherwise similarly affected by any of the following:

(a)Any lack of genuineness, legality, validity, enforceability or allowability (in a bankruptcy, insolvency, reorganization or similar proceeding, or otherwise), or any avoidance or subordination, in whole or in part, of any Loan Document or any of the Guarantied Obligations and regardless of any Law, regulation or order now or hereafter in effect in any jurisdiction affecting any of the Guarantied Obligations, any of the terms of the Loan Documents, or any rights of the Agent or the Banks or any other Person with respect thereto;

(b)Any increase, decrease, or change in the amount, nature, type or purpose of any of, or any release, surrender, exchange, compromise or settlement of any of the Guarantied Obligations (whether or not contemplated by the Loan Documents as presently constituted); any change in the time, manner, method, or place of payment or performance of, or in any other term of, any of the Guarantied Obligations; any execution or delivery of any additional Loan Documents; or any amendment, modification or supplement to, or renewals, extensions, refinancing or refunding of any Loan Document or any of the Guarantied Obligations;

(c)Any failure to assert any breach of or default under any Loan Document or any of the Guarantied Obligations; any extensions of credit in excess of the amount committed under or contemplated by the Loan Documents, or in circumstances in which any condition to such extensions of credit has not been satisfied; any other exercise or non-exercise, or any other failure, omission, breach, default, delay, or wrongful action in connection with any exercise or non-exercise, of any right or remedy against the Borrower or any other Person under or in connection with any Loan Document or any of the Guarantied Obligations; any refusal of payment or performance of any of the Guarantied Obligations, whether or not with any reservation of rights against any Guarantor; or any application of collections (including but not limited to collections resulting from realization upon any direct or indirect security for the Guarantied Obligations) to other obligations, if any, not entitled to the benefits of this Guaranty, in preference to Guarantied Obligations entitled to the benefits of this Guaranty, or if any collections are applied to Guarantied Obligations, any application to particular Guarantied Obligations;

(d)Any taking, exchange, amendment, modification, waiver, supplement, termination, subordination, compromise, release, surrender, loss, or impairment of, or any failure to protect, perfect, or preserve the value of, or any enforcement of, realization upon, or exercise of rights, or remedies under or in connection with, or any failure, omission, breach, default, delay, or wrongful action by the Agent or the Banks, or any of them, or any other Person in connection with the enforcement of, realization upon, or exercise of rights or remedies under or in connection with, or, any other action or inaction by the Agent or the Banks, or any of them, or any other Person in respect of, any direct or indirect security for any of the Guarantied Obligations. As used in this Guaranty, “direct or indirect security” for the Guarantied Obligations, and similar phrases, includes any collateral security, guaranty, suretyship, letter of credit, capital maintenance agreement, put option, subordination agreement, or other right or arrangement of any nature providing direct or indirect assurance of payment or performance of any of the Guarantied Obligations, made by or on behalf of any Person;

(e)Any merger, consolidation, liquidation, dissolution, winding-up, charter revocation, or forfeiture, or other change in, restructuring or termination of the corporate structure or existence of, any Borrower or any other Person; any bankruptcy, insolvency, reorganization or similar proceeding under the laws of Japan or any other country with respect to the Borrower or any other Person; or any action taken or election made by the Agent or the Banks, or any of them (including but not limited to any election under Section 1111(b)(2) of the United States Bankruptcy Code), the Borrower, or any other Person in connection with any such proceeding;

(f)Any defense, setoff, or counterclaim which may at any time be available to or be asserted by any Borrower or any other person with respect to any Loan Document or any of the Guarantied Obligations; or any discharge by operation of law or release of the Borrower or any other Person from the performance or observance of any Loan Document or any of the Guarantied Obligations; or

(g)Any other event or circumstance, whether similar or dissimilar to the foregoing, and whether known or unknown, which might otherwise constitute a defense available to, or limit the liability of, any Guarantor, a guarantor or a surety, excepting only full, strict, and indefeasible payment and performance of the Guarantied Obligations in full.

Each Guarantor acknowledges, consents, and agrees that new Guarantors may join in this Guaranty and each Guarantor affirms that its obligations shall continue hereunder undiminished.

4.Waivers, etc. Each of the Guarantors hereby waives any defense to or limitation on its obligations under this Guaranty arising out of or based on any event or circumstance referred to in Section 3 hereof. Without limitation and to the fullest extent permitted by applicable Law, each Guarantor waives each of the following:

(a)All notices, disclosures and demand of any nature which otherwise might be required from time to time to preserve intact any rights against any Guarantor, including the following: any notice of any event or circumstance described in Section 3 hereof; any notice required by any Law, regulation or order now or hereafter in effect in any jurisdiction; any notice of nonpayment, nonperformance, dishonor, or protest under any Loan Document or any of the Guarantied Obligations; any notice of the incurrence of any Guarantied Obligation; any notice of any default or any failure on the part of the Borrower or any other Person to comply with any Loan Document or any of the Guarantied Obligations or any direct or indirect security for any of the Guarantied Obligations; and any notice of any information pertaining to the business, operations, condition (financial or otherwise) or prospects of the Borrower or any other Person;

(b)Any right to any marshalling of assets, to the filing of any claim against the Borrower or any other Person in the event of any bankruptcy, insolvency, reorganization or similar proceeding, or to the exercise against the Borrower or any other Person of any other right or remedy under or in connection with any Loan Document or any of the Guarantied Obligations or any direct or indirect security for any of the Guarantied Obligations; any requirement of promptness or diligence on the part of the Agent or the Banks, or any of them, or any other Person; any requirement to exhaust any remedies under or in connection with, or to mitigate the damages resulting from default under, any Loan Document or any of the Guarantied Obligations or any direct or indirect security for any of the Guarantied Obligations; any benefit of any statute of limitations; and any requirement of acceptance of this Guaranty or any other Loan Document, and any requirement that any Guarantor receive notice of any such acceptance;

(c)Any defense or other right arising by reason of any Law now or hereafter in effect in any jurisdiction pertaining to election of remedies (including but not limited to anti-deficiency laws, “one action” laws or the like), or by reason of any election of remedies or other action or inaction by the Agent or the Banks, or any of them (including but not limited to commencement or completion of any judicial proceeding or nonjudicial sale or other action in respect of collateral security for any of the Guarantied Obligations), which results in denial or impairment of the right of the Agent or the Banks, or any of them, to seek a deficiency against the Borrower or any other Person or which otherwise discharges or impairs any of the Guarantied Obligations; and

(d)Any and all defenses it may now or hereafter have based on principles of suretyship, impairment of collateral, or the Like.

5.Reinstatement. This Guaranty is a continuing obligation of the Guarantors and shall remain in full force and effect notwithstanding that no Guarantied Obligations may be outstanding from time to time and notwithstanding any other event or circumstance. Upon termination of all Commitments, and indefeasible payment in full of all Guarantied Obligations, this Guaranty shall terminate; provided, however, that this Guaranty shall continue to be effective or be reinstated, as the case may be, any time any payment of any of the Guarantied Obligations is rescinded, recouped, avoided, or must otherwise be returned or released by any Bank or Agent upon

or during the insolvency, bankruptcy, or reorganization of, or any similar proceeding affecting, the Borrower or for any other reason whatsoever, all as though such payment had not been made and was due and owing.

6.Subrogation. Each Guarantor waives and agrees it will not exercise any rights against Borrower or any other Guarantor arising in connection with, or any Collateral securing, the Guarantied Obligations (including rights of subrogation, contribution, and the like) until the Guarantied Obligations have been indefeasibly paid in full, and all Commitments have been terminated. If any amount shall be paid to any Guarantor by or on behalf of the Borrower or any other Guarantor by virtue of any right of subrogation, contribution, or the like, such amount shall be deemed to have been paid to such Guarantor for the benefit of, and shall be held in trust for the benefit of, the Agent and the Banks and shall forthwith be paid to the Agent to be credited and applied upon the Guarantied Obligations, whether matured or unmatured, in accordance with the terms of the Credit Agreement.

7.No Stay. Without limitation of any other provision of this Guaranty, if any declaration of default or acceleration or other exercise or condition to exercise of rights or remedies under or with respect to any Guarantied Obligation shall at any time be stayed, enjoined, or prevented for any reason (including but not limited to stay or injunction resulting from the pendency against the Borrower or any other Person of a bankruptcy, insolvency, reorganization or similar proceeding), the Guarantors agree that, for the purposes of this Guaranty and their obligations hereunder, the Guarantied Obligations shall be deemed to have been declared in default or accelerated, and such other exercise or conditions to exercise shall be deemed to have been taken or met.

9.Notices. Each Guarantor agrees that all notices, statements, requests, demands and other communications under this Guaranty shall be given to such Guarantor at the address set forth on a Schedule to, or in a Guarantor Joinder and Assumption Agreement given under, the Credit Agreement and in the manner provided in Section 11.6 [Notices] of the Credit Agreement. The Agent and the Banks may rely on any notice (whether or not made in a manner contemplated by this Guaranty) purportedly made by or on behalf of a Guarantor, and the Agent and the Banks shall have no duty to verify the identity or authority of the Person giving such notice.

10.Counterparts; Telecopy Signatures. This Guaranty may be executed in any number of counterparts, each of which, when so executed, shall be deemed an original, but all such counterparts shall constitute but one and the same instrument. Each Guarantor acknowledges and agrees that a telecopy transmission to Agent or any Bank of signature pages hereof purporting to be signed on behalf of any Guarantor shall constitute effective and binding execution and delivery hereof by such Guarantor.

(a)In the event that at any time any obligation of the Guarantors now or hereafter existing under this Guaranty shall have become due and payable, the Agent and the Banks, or any of them, shall have the right from time to time, without notice to any Guarantor, to set off against and apply to such due and payable amount any obligation of any nature of any Bank or the Agent, or any subsidiary or affiliate of any Bank or Agent, to any Guarantor, including but not limited to all deposits (whether time or demand, general or special, provisionally credited or finally credited, however evidenced) now or hereafter maintained by any Guarantor with the Agent or any Bank. Such right shall be absolute and unconditional in all circumstances and, without limitation, shall exist whether or not the Agent or the Banks, or any of them, shall have given any notice or made any demand under this Guaranty or under such obligation to the Guarantor, whether such obligation to the Guarantor is absolute or contingent, matured or unmatured (it being agreed that the Agent and the Banks, or any of them, may deem such obligation to be then due and payable at the time of such setoff), and regardless of the existence or adequacy of any collateral, guaranty, or other direct or indirect security or right or remedy available to the Agent or any of the Banks. The rights of the Agent and the Banks under this Section are in addition to such other rights and remedies (including, without limitation, other rights of setoff and banker’s lien) which the Agent and the Banks, or any of them, may have, and nothing in this Guaranty or in any other Loan Document shall be deemed a waiver of or restriction on the right of setoff or banker’s lien of the Agent and the Banks, or any of them. Each of the Guarantors hereby agrees that, to the fullest extent permitted by Law, any affiliate or subsidiary of the Agent or any of the Banks and any holder of a participation in any obligation of any Guarantor under this Guaranty, shall have the same

rights of setoff as the Agent and the Banks as provided in this Section (regardless whether such affiliate or participant otherwise would be deemed a creditor of the Guarantor).

(b)Upon the occurrence and during the continuation of any default under any Guarantied Obligation, if any amount shall be paid to any Guarantor by or for the account of Borrower, such amount shall be held in trust for the benefit of each Bank and Agent and shall forthwith be paid to the Agent to be credited and applied to the Guarantied Obligations when due and payable.

12.Construction. The section and other headings contained in this Guaranty are for reference purposes only and shall not affect interpretation of this Guaranty in any respect. This Guaranty has been fully negotiated between the applicable parties, each party having the benefit of legal counsel, and accordingly neither any doctrine of construction of guaranties or suretyships in favor of the guarantor or surety, nor any doctrine of construction of ambiguities in agreement or instruments against the party controlling the drafting thereof, shall apply to this Guaranty.

13.Successors and Assigns. This Guaranty shall be binding upon each Guarantor, its successors and assigns, and shall inure to the benefit of and be enforceable by the Agent and the Banks, or any of them, and their successors and permitted assigns; provided, however, that no Guarantor may assign or transfer any of its rights or obligations hereunder or any interest herein and any such purported assignment or transfer shall be null and void. Without limitation of the foregoing, the Agent and the Banks, or any of them (and any successive assignee or transferee), from time to time may assign or otherwise transfer all or any portion of its rights or obligations under the Loan Documents (including all or any portion of any commitment to extend credit), or any other Guarantied Obligations, to any other person and such Guarantied Obligations (including any Guarantied Obligations resulting from extension of credit by such other Person under or in connection with the Loan Documents) shall be and remain Guarantied Obligations entitled to the benefit of this Guaranty, and to the extent of its interest in such Guarantied Obligations such other Person shall be vested with all the benefits in respect thereof granted to the Agent and the Banks in this Guaranty or otherwise.

(a)Governing Law. This Guaranty shall be governed by, construed, and enforced in accordance with, the internal Laws of the Commonwealth of Pennsylvania, without regard to conflict of laws principles.

(i)Submits to the nonexclusive jurisdiction of any state or federal court sitting in Allegheny County, in any action or proceeding arising out of or relating to this Agreement, and each Guarantor hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such state or federal court. Each Guarantor hereby waives to the fullest extent it may effectively do so, the defense of an inconvenient forum to the maintenance of any such action or proceeding.

(ii)Waives any objection to jurisdiction and venue of any action instituted against it as provided herein and agrees not to assert any defense based on lack of jurisdiction or venue; and

(iii)WAIVES TRIAL BY JURY IN ANY ACTION, SUIT, PROCEEDING, OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATED TO THIS GUARANTY, THE CREDIT AGREEMENT, OR ANY OTHER LOAN DOCUMENT TO THE FULLEST EXTENT PERMITTED BY LAW.

(a)It is the intention of the parties that this Guaranty be enforceable to the fullest extent permissible under applicable Law, but that the unenforceability (or modification to conform to such Law) of any provision or provisions hereof shall not render unenforceable, or impair, the remainder hereof. If any provision in this Guaranty shall be held invalid or unenforceable in whole or in part in any jurisdiction, this Guaranty shall, as to such jurisdiction, be deemed amended to modify or delete, as necessary, the offending provision or provisions and to alter

the bounds thereof in order to render it or them valid and enforceable to the maximum extent permitted by applicable Law, without in any manner affecting the validity or enforceability of such provision or provisions in any other jurisdiction or the remaining provisions hereof in any jurisdiction.

(b)Without limitation of the preceding subsection (a), to the extent that applicable Law (including applicable Laws pertaining to fraudulent conveyance or fraudulent or preferential transfer) otherwise would render the full amount of the Guarantor’s obligations hereunder invalid, voidable, or unenforceable on account of the amount of a Guarantor’s aggregate liability under this Guaranty, then, notwithstanding any other provision of this Guaranty to the contrary, the aggregate amount of such liability shall, without any further action by the Agent or any of the Banks or such Guarantor or any other Person, be automatically limited and reduced to the highest amount which is valid and enforceable as determined in such action or proceeding, which (without limiting the generality of the foregoing) may be an amount which is equal to the greater of:

(i)the fair consideration actually received by such Guarantor under the terms and as a result of the Loan Documents and the value of the benefits described in this Section 15 (b) hereof, including (and to the extent not inconsistent with applicable federal and state Laws affecting the enforceability of guaranties) distributions, commitments, and advances made to or for the benefit of such Guarantor with the proceeds of any credit extended under the Loan Documents, or

(ii)the excess of (A) the amount of the fair value of the assets of such Guarantor as of the date of this Guaranty as determined in accordance with applicable federal and state Laws governing determinations of the insolvency of debtors as in effect on the date hereof, over (B) the amount of all liabilities of such Guarantor as of the date of this Guaranty, also as determined on the basis of applicable federal and state Laws governing the insolvency of debtors as in effect on the date hereof.

(c)Notwithstanding anything to the contrary in this Section or elsewhere in this Guaranty, this Guaranty shall be presumptively valid and enforceable to its full extent in accordance with its terms, as if this Section (and references elsewhere in this Guaranty to enforceability to the fullest extent permitted by Law) were not a part of this Guaranty, and in any related litigation the burden of proof shall be on the party asserting the invalidity or unenforceability of any provision hereof or asserting any limitation on any Guarantor’s obligations hereunder as to each element of such assertion.

16.Additional Guarantors. At any time after the initial execution and delivery of this Guaranty to the Agent and the Banks, additional Persons may become parties to this Guaranty and thereby acquire the duties and rights of being Guarantors hereunder by executing and delivering to the Agent and the Banks a Guarantor Joinder pursuant to the Credit Agreement. No notice of the addition of any Guarantor shall be required to be given to any pre-existing Guarantor and each Guarantor hereby consents thereto.

The obligations and additional liabilities of the Guarantors under this Guaranty are joint and several obligations of the Guarantors, and each Guarantor hereby waives to the full extent permitted by Law any defense it may otherwise have to the payment and performance of the Obligations that its liability hereunder is limited and not joint and several. Each Guarantor acknowledges and agrees that the foregoing waivers and those set forth below serve as a material inducement to the agreement of the Agent and the Banks to make the Loans, and that the Agent and the Banks are relying on each specific waiver and all such waivers in entering into this Guaranty. The undertakings of each Guarantor hereunder secure the obligations of itself and the other Guarantors. The Agent and the Banks, or any of them, may, in their sole discretion, elect to enforce this Guaranty against any Guarantor without any duty or responsibility to pursue any other Guarantor and such an election by the Agent and the Banks, or any of them, shall not be a defense to any action the Agent and the Banks, or any of them, may elect to take against any Guarantor. Each of the Banks and Agent hereby reserve all rights against each Guarantor.

(a)Each Guarantor hereby acknowledges that it has received a copy of the Credit Agreement and the other Loan Documents and each Guarantor certifies that the representations and warranties made therein with respect to such Guarantor are true and correct. Further, each Guarantor acknowledges and agrees to perform, comply with, and be bound by all of the provisions of the Credit Agreement and the other Loan Documents.

(b)Each Guarantor hereby acknowledges, represents, and warrants that it receives direct and indirect benefits by virtue of its affiliation with Borrower and the other Guarantors and that it will receive direct and indirect benefits from the financing arrangements contemplated by the Credit Agreement and that such benefits, together with the rights of contribution and subrogation that may arise in connection herewith are a reasonably equivalent exchange of value in return for providing this Guaranty.

(a)Generality of Certain Terms. As used in this Guaranty, the terms “hereof”, “herein” and terms of similar import refer to this Guaranty as a whole and not to any particular term or provision; the term “including”, as used herein, is not a term of limitation and means “including without limitation”.

(b)Amendments, Waivers. No amendment to or waiver of any provision of this Guaranty, and no consent to any departure by any Guarantor herefrom, shall in any event be effective unless in a writing manually signed by or on behalf of the Agent and the Banks. Any such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No delay or failure of the Agent or the Banks, or any of them, in exercising any right or remedy under this Guaranty shall operate as a waiver thereof; nor shall any single or partial exercise of any such right or remedy preclude any other or further exercise thereof or the exercise of any other right or remedy. The rights and remedies of the Agent and the Banks under this Guaranty are cumulative and not exclusive of any other rights or remedies available hereunder, under any other agreement or instrument, by Law, or otherwise.

(c)Telecommunications. Each Bank and Agent shall be entitled to rely on the authority of any individual making any telecopy, electronic or telephonic notice, request, or signature without the necessity of receipt of any verification thereof.

(d)Expenses. Each Guarantor unconditionally agrees to pay all costs and expenses, including reasonable attorney’s fees incurred by the Agent or any of the Banks in enforcing this Guaranty against any Guarantor and each Guarantor shall pay and indemnify each Bank and Agent for, and hold it harmless from and against, any and all obligations, liabilities, losses, damages, costs, expenses (including disbursements and reasonable legal fees of counsel to any Bank or Agent), penalties, judgments, suits, actions, claims, and disbursements imposed on, asserted against, or incurred by any Bank or Agent (except as may result from the gross negligence or willful misconduct of Agent or any Bank):

(i)relating to the preparation, negotiation, execution, administration, or enforcement of or collection under this Guaranty or any document, instrument, or agreement relating to any of the Obligations, including in any bankruptcy, insolvency, or similar proceeding in any jurisdiction or political subdivision thereof;

(ii)relating to any amendment, modification, waiver, or consent hereunder or relating to any telecopy or telephonic transmission purporting to be by any Guarantor or Borrower; and

(iii)in any way relating to or arising out of this Guaranty, or any document, instrument, or agreement relating to any of the Guarantied Obligations, or any action taken or omitted to be taken by any Bank or Agent hereunder, and including those arising directly or indirectly from the violation or asserted violation by any Guarantor or Borrower or Agent or any Bank of any Law, rule, regulation, judgment, order, or the like of any jurisdiction or political subdivision thereof (including those relating to environmental protection, health, labor, importing, exporting, or safety) and regardless whether asserted by any governmental entity or any other Person.

(e)Prior Understandings. This Guaranty and the Credit Agreement constitute the entire agreement of the parties hereto with respect to the subject matter hereof and supersede any and all other prior and contemporaneous understandings and agreements.

(f)Survival. All representations and warranties of the Guarantors made in connection with this Guaranty shall survive, and shall not be waived by, the execution and delivery of this Guaranty, any investigation by or knowledge of the Agent and the Banks, or any of them, any extension of credit, or any other event or circumstance whatsoever.

IN WITNESS WHEREOF, the undersigned parties intending to be legally bound, have executed this Guaranty as of the date first above written with the intention that this Guaranty shall constitute a sealed instrument.
