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. 

2.7.2 Swing Loan Note

 2.8.2 Borrowings to Repay Swing Loans. 

PNC Bank may, at its option, exercisable at any time for any reason whatsoever, demand repayment of the Swing Loans, and
each Bank shall make a Revolving Credit Loan in an amount equal to such Bank’s Ratable Share of the aggregate principal amount of the outstanding Swing Loans, plus, if PNC Bank so requests, accrued interest thereon, provided that no Bank
shall be obligated in any event to make Revolving Credit Loans in excess of its Revolving Credit Commitment. Revolving Credit Loans made pursuant to the preceding sentence shall bear interest at the Base Rate Option and shall be deemed to have been
properly requested in accordance with Section 2.5.1 without regard to any of the requirements of that provision. PNC Bank shall provide notice to the Banks (which may be telephonic or written notice by letter, facsimile or telex) that such
Revolving Credit Loans are to be made under this Section 2.8.2 and of the apportionment among the Banks, and the Banks shall be unconditionally obligated to fund such Revolving Credit Loans (whether or not the conditions specified in
Section 2.5.1 are then satisfied) by the time PNC Bank so requests, which shall not be earlier than 3:00 p.m. Pittsburgh time on the next Business Day after the date the Banks receive such notice from PNC Bank. 

2.9 Letter of Credit Subfacility. 
 2.9.1. Issuance of Letters of Credit. 
 Borrower may request
the issuance of a letter of credit (each a “Letter of Credit”) on behalf of itself or another Loan Party by delivering or having such other Loan Party deliver to the Agent a completed application and agreement for letters of credit in such
form as the Agent may specify from time to time by no later than 10:00 a.m., Pittsburgh time, at least three (3) Business Days, or such shorter period as may be agreed to by the Agent, in advance of the proposed date of issuance. Subject to the
terms and conditions hereof and in reliance on the agreements of the other Banks set forth in this Section 2.9, the Agent or any of the Agent’s Affiliates will issue a Letter of Credit provided that each Letter of Credit shall
(A) have a maximum maturity of twelve (12) months from the date of issuance, and (B) in no event expire later than ten (10) Business Days prior to the Expiration Date (unless such letter of credit is secured by cash collateral

(i) the Letters of Credit Outstanding exceed, at any one time, $5,000,000 or (ii) the Revolving Facility Usage exceed, at any one time, the Revolving Credit Commitments. Letters of Credit outstanding under the Existing Credit Facility on
the Closing Date shall be deemed to be outstanding under this Agreement on and after the Closing Date. 

  
 - 26 -









 2.9.2. Letter of Credit Fees. 

The Borrower shall pay (i) to the Agent for the ratable account of the Banks a fee (the “Letter of Credit
Fee”) equal to the Applicable Margin per annum which would be applicable to Loans for which the Euro-Rate Option has been selected, as such Applicable Margin may change from time to time as provided in this Agreement, and (ii) at any time
that there are two or more Banks, to the Agent for its own account a fronting fee equal to .125% (12.50 basis points) per annum (computed on the basis of a year of 360 days and actual days elapsed), which fees shall be computed on the daily average
Letters of Credit Outstanding and shall be payable quarterly in arrears commencing with the first Business Day of each January, April, July and October following issuance of each Letter of Credit and on the Expiration Date. The Borrower shall also
pay to the Agent for the Agent’s sole account the Agent’s then in effect customary fees and administrative expenses payable with respect to the Letters of Credit as the Agent may generally charge or incur from time to time in connection
with the issuance, maintenance, modification (if any), assignment or transfer (if any), negotiation, and administration of Letters of Credit. 
 2.9.3. Disbursements, Reimbursement. 
 2.9.3.1 Immediately
upon the Issuance of each Letter of Credit, each Bank shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Agent a participation in such Letter of Credit and each drawing thereunder in an amount equal to such
Bank’s Ratable Share of the maximum amount available to be drawn under such Letter of Credit and the amount of such drawing, respectively. 
 2.9.3.2 In the event of any request for a drawing under a Letter of Credit by the beneficiary or transferee thereof, the Agent will promptly notify the Borrower. Provided that it shall have received such
notice, the Borrower shall reimburse (such obligation to reimburse the Agent shall sometimes be referred to as a “Reimbursement Obligation”) the Agent prior to 12:00 noon, Pittsburgh time on each date that an amount is paid by the Agent
under any Letter of Credit (each such date, an “Drawing Date”) in an amount equal to the amount so paid by the Agent. In the event the Borrower fails to reimburse the Agent for the full amount of any drawing under any Letter of Credit by
12:00 noon, Pittsburgh time, on the Drawing Date, the Agent will promptly notify each Bank thereof, and the Borrower shall be deemed to have requested that Revolving Credit Loans be made by the Banks under the Base Rate Option to be disbursed on the
Drawing Date under such Letter of Credit, subject to the amount of the unutilized portion of the Revolving Credit Commitment and subject to the conditions set forth in Section 7.2 [Each Additional Loan] other than any notice
requirements. Any notice given by the Agent pursuant to this Section 2.9.3.2 may be oral if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect
of such notice. 
 2.9.3.3 Each Bank shall upon any notice pursuant to Section 2.9.3.2 make available
to the Agent an amount in immediately available funds equal to its Ratable Share of the amount of the drawing, whereupon the participating Banks shall (subject 

  
 - 27 -









 
to Section 2.9.3.4) each be deemed to have made a Revolving Credit Loan under the Base Rate Option to the Borrower in that amount. If any Bank so notified fails to make available to
the Agent for the account of the Agent the amount of such Bank’s Ratable Share of such amount by no later than 2:00 p.m., Pittsburgh time on the Drawing Date, then interest shall accrue on such Bank’s obligation to make such payment, from
the Drawing Date to the date on which such Bank makes such payment (i) at a rate per annum equal to the Federal Funds Effective Rate during the first three days following the Drawing Date and (ii) at a rate per annum equal to the rate
applicable to Loans under the Revolving Credit Base Rate Option on and after the fourth day following the Drawing Date. The Agent will promptly give notice of the occurrence of the Drawing Date, but failure of the Agent to give any such notice on
the Drawing Date or in sufficient time to enable any Bank to effect such payment on such date shall not relieve such Bank from its obligation under this Section 2.9.3.3. 

2.9.3.4 With respect to any unreimbursed drawing that is not converted into Revolving Credit Loans under the Base Rate
Option to the Borrower in whole or in part as contemplated by Section 2.9.3.2, because of the Borrower’s failure to satisfy the conditions set forth in Section 7.2 [Each Additional Loan] other than any notice
requirements or for any other reason, the Borrower shall be deemed to have incurred from the Agent a borrowing (each a “Letter of Credit Borrowing”) in the amount of such drawing. Such Letter of Credit Borrowing shall be due and payable on
demand (together with interest) and shall bear interest at the rate per annum applicable to the Revolving Credit Loans under the Base Rate Option. Each Bank’s payment to the Agent pursuant to Section 2.9.3.3 shall be deemed to be a
payment in respect of its participation in such Letter of Credit Borrowing and shall constitute a “Participation Advance” from such Bank in satisfaction of its participation obligation under this Section 2.9.3. 

2.9.4. Repayment of Participation Advances. 

2.9.4.1 Upon (and only upon) receipt by the Agent for its account of immediately available funds from the Borrower
(i) in reimbursement of any payment made by the Agent under the Letter of Credit with respect to which any Bank has made a Participation Advance to the Agent, or (ii) in payment of interest on such a payment made by the Agent under such a
Letter of Credit, the Agent will pay to each Bank, in the same funds as those received by the Agent, the amount of such Bank’s Ratable Share of such funds, except the Agent shall retain the amount of the Ratable Share of such funds of any Bank
that did not make a Participation Advance in respect of such payment by Agent. 
 2.9.4.2 If the Agent is
required at any time to return to any Loan Party, or to a trustee, receiver, liquidator, custodian, or any official in any Insolvency Proceeding, any portion of the payments made by any Loan Party to the Agent pursuant to Section 2.9.4.1
in reimbursement of a payment made under the Letter of Credit or interest or fee thereon, each Bank shall, on demand of the Agent, forthwith return to the Agent the amount of its Ratable Share of any amounts so returned by the Agent plus interest
thereon from the date such demand is made to the date such amounts are returned by such Bank to the Agent, at a rate per annum equal to the Federal Funds Effective Rate in effect from time to time. 

  
 - 28 -









 2.9.5. Documentation. 

Each Loan Party agrees to be bound by the terms of the Agent’s application and agreement for letters of credit and
the Agent’s written regulations and customary practices relating to letters of credit, though such interpretation may be different from such Loan Party’s own. In the event of a conflict between such application or agreement and this
Agreement, this Agreement shall govern. It is understood and agreed that, except in the case of gross negligence or willful misconduct, the Agent shall not be liable for any error, negligence and/or mistakes, whether of omission or commission, in
following any Loan Party’s instructions or those contained in the Letters of Credit or any modifications, amendments or supplements thereto. 
 2.9.6. Determinations to Honor Drawing Requests. 
 In
determining whether to honor any request for drawing under any Letter of Credit by the beneficiary thereof, the Agent shall be responsible only to determine that the documents and certificates required to be delivered under such Letter of Credit
have been delivered and that they comply on their face with the requirements of such Letter of Credit. 
 2.9.7.
Nature of Participation and Reimbursement Obligations. 
 Each Bank’s obligation in accordance with
this Agreement to make the Revolving Credit Loans or Participation Advances, as contemplated by Section 2.9.3, as a result of a drawing under a Letter of Credit, and the Obligations of the Borrower to reimburse the Agent upon a draw
under a Letter of Credit, shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Section 2.9 under all circumstances, including the following circumstances: 

(i) any set-off, counterclaim, recoupment, defense or other right which such Bank may have against the Agent or any of
its Affiliates, the Borrower or any other Person for any reason whatsoever; 
 (ii) the failure of any Loan
Party or any other Person to comply, in connection with a Letter of Credit Borrowing, with the conditions set forth in Section 2.1 [Revolving Credit Commitments], 2.5 [Revolving Credit Loan Requests], 2.6 [Making Revolving
Credit Loans] or 7.2 [Each Additional Loan] or as otherwise set forth in this Agreement for the making of a Revolving Credit Loan, it being acknowledged that such conditions are not required for the making of a Letter of Credit Borrowing and
the obligation of the Banks to make Participation Advances under Section 2.9.3; 
 (iii) any lack of
validity or enforceability of any Letter of Credit; 
 (iv) any claim of breach of warranty that might be made
by any Loan Party or any Bank against any beneficiary of a Letter of Credit, or the existence of any claim, set-off, recoupment, counterclaim, crossclaim, defense or other right which any Loan


  
 - 29 -









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

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

(vi) payment by the Agent or any of its Affiliates under any Letter of Credit against presentation of a demand, draft or
certificate or other document which does not comply with the terms of such Letter of Credit; 
 (vii) the
solvency of, or any acts or omissions by, any beneficiary of any Letter of Credit, or any other Person having a role in any transaction or obligation relating to a Letter of Credit, or the existence, nature, quality, quantity, condition, value or
other characteristic of any property or services relating to a Letter of Credit; 
 (viii) any failure by the
Agent or any of Agent’s Affiliates to issue any Letter of Credit in the form requested by any Loan Party, unless the Agent has received written notice from such Loan Party of such failure within three Business Days after the Agent shall have
furnished such Loan Party a copy of such Letter of Credit and such error is material and no drawing has been made thereon prior to receipt of such notice; 
 (ix) any adverse change in the business, operations, properties, assets, condition (financial or otherwise) or prospects of any Loan Party or Subsidiaries of a Loan Party; 

(x) any breach of this Agreement or any other Loan Document by any party thereto; 

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

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

(xiii) the fact that the Expiration Date shall have passed or this Agreement or the Commitments hereunder shall have been
terminated; and 

  
 - 30 -









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

In addition to amounts payable as provided in Section 10.5 [Reimbursement of Agent by Borrower, Etc.], the
Borrower hereby agrees to protect, indemnify, pay and save harmless the Agent and any of Agent’s Affiliates that has issued a Letter of Credit from and against any and all claims, demands, liabilities, damages, taxes, penalties, interest,
judgments, losses, costs, charges and expenses (including reasonable fees, expenses and disbursements of counsel and allocated costs of internal counsel) which the Agent or any of Agent’s Affiliates may incur or be subject to as a consequence,
direct or indirect, of the issuance of any Letter of Credit, other than as a result of (A) the gross negligence or willful misconduct of the Agent as determined by a final judgment of a court of competent jurisdiction or (B) the wrongful
dishonor by the Agent or any of Agent’s Affiliates of a proper demand for payment made under any Letter of Credit, except if such dishonor resulted from any act or omission, whether rightful or wrongful, of any present or future de jure or de
facto government or governmental authority (all such acts or omissions herein called “Governmental Acts”). To the extent the Issuing Bank is not indemnified by the Borrower, the Banks will reimburse and indemnify the Issuing Bank, in
proportion to their respective Ratable Shares, for and against any and all liabilities, obligations, losses, damages, penalties, claims, actions, judgments, costs, expenses or disbursements of whatsoever kind or nature that may be imposed on,
asserted against, or incurred by the Issuing Bank in performing its respective duties in any way related to or arising out of the Letter(s) of Credit issued by the Issuing Bank; provided, however, that no Bank shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, claims, actions, judgments, costs, expenses or disbursements resulting from the gross negligence or willful misconduct of the Issuing Bank or an Affiliate of the Issuing Bank. 

2.9.9. Liability for Acts and Omissions. 

As between any Loan Party, Bank issuer and the Agent, or the Agent’s Affiliates, such Loan Party assumes all risks of
the acts and omissions of, or misuse of the Letters of Credit by, the respective beneficiaries of such Letters of Credit. In furtherance and not in limitation of the foregoing, the Agent shall not be responsible for any of the following including
any losses or damages to any Loan Party or other Person or property relating therefrom: (i) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for an
issuance of any such Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged (even if the Agent or the Agent’s Affiliates shall have been notified thereof);
(ii) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any such Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason; (iii) the failure of the beneficiary of any such Letter of Credit, or any other party to which such Letter of Credit may be transferred, to comply fully with any conditions required in order to draw upon
such Letter of Credit or any other claim of any Loan Party against any beneficiary of 

  
 - 31 -









 
such Letter of Credit, or any such transferee, or any dispute between or among any Loan Party and any beneficiary of any Letter of Credit or any such transferee; (iv) errors, omissions,
interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex or otherwise, whether or not they be in cipher; (v) errors in interpretation of technical terms; (vi) any loss or delay in the
transmission or otherwise of any document required in order to make a drawing under any such Letter of Credit or of the proceeds thereof; (vii) the misapplication by the beneficiary of any such Letter of Credit of the proceeds of any drawing
under such Letter of Credit; or (viii) any consequences arising from causes beyond the control of the Agent or the Agent’s Affiliates, as applicable, including any Governmental Acts, and none of the above shall affect or impair, or prevent
the vesting of, any of the Agent’s or the Agent’s Affiliates rights or powers hereunder. Nothing in the preceding sentence shall relieve the Agent from liability for the Agent’s gross negligence or willful misconduct in connection
with actions or omissions described in such clauses (i) through (viii) of such sentence. In no event shall the Agent or the Agent’s Affiliates be liable to any Loan Party for any indirect, consequential, incidental, punitive,
exemplary or special damages or expenses (including without limitation attorneys’ fees), or for any damages resulting from any change in the value of any property relating to a Letter of Credit. 

Without limiting the generality of the foregoing, the Agent and each of its Affiliates (i) may rely on any oral or
other communication believed in good faith by the Agent or such Affiliate to have been authorized or given by or on behalf of the applicant for a Letter of Credit, (ii) may honor any presentation if the documents presented appear on their face
substantially to comply with the terms and conditions of the relevant Letter of Credit; (iii) may honor a previously dishonored presentation under a Letter of Credit, whether such dishonor was pursuant to a court order, to settle or compromise
any claim of wrongful dishonor, or otherwise, and shall be entitled to reimbursement to the same extent as if such presentation had initially been honored, together with any interest paid by the Agent or its Affiliate; (iv) may honor any
drawing that is payable upon presentation of a statement advising negotiation or payment, upon receipt of such statement (even if such statement indicates that a draft or other document is being delivered separately), and shall not be liable for any
failure of any such draft or other document to arrive, or to conform in any way with the relevant Letter of Credit; (v) may pay any paying or negotiating bank claiming that it rightfully honored under the laws or practices of the place where
such bank is located; and (vi) may settle or adjust any claim or demand made on the Agent or its Affiliate in any way related to any order issued at the applicant’s request to an air carrier, a letter of guarantee or of indemnity issued to
a carrier or any similar document (each an “Order”) and honor any drawing in connection with any Letter of Credit that is the subject to such Order, notwithstanding that any drafts or other documents presented in connection with such
Letter of Credit fail to conform in any way with such Letter of Credit. 
 In furtherance and extension and not
in limitation of the specific provisions set forth above, any action taken or omitted by the Agent or the Agent’s Affiliates under or in connection with the Letters of Credit issued by it or any documents and certificates delivered thereunder,
if taken or omitted in good faith, shall not put the Agent or the Agent’s Affiliates under any resulting liability to the Borrower or any Bank.

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 $1,000,000 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. 
 2.11 Increase in
Commitments. 
 2.11.1 Increasing Banks and New Banks. 

The Borrower shall have the right to make up to four (4) requests prior to the Expiration Date that: (1) the
current Banks (the “Existing Banks”) increase their Revolving Credit Commitments (an Existing Bank which elects to increase its Revolving Credit Commitment shall be referred to as an “Increasing Bank”) and/or (2) one or more
new Banks (each a “New Bank”) join this Agreement and provide a Revolving Credit Commitment hereunder, subject to the following terms and conditions: 
 (i) No Obligation to Increase. No Existing Bank shall be obligated to increase its Revolving Credit Commitment and any increase in the Revolving Credit Commitment and any increase in the Revolving
Credit Commitment by any Existing Bank shall be in the sole discretion of such Existing Bank. 
 (ii)
Defaults. There shall exist no Event of Default on the effective date of such increase (the “Revolving Credit Commitment Increase Date”) after giving effect to such increase. 

(iii) Aggregate Revolving Credit Commitments. After giving effect to any such increase, the total Revolving Credit
Commitments shall not exceed $80,000,000 and the total aggregate amount of all such increases shall not exceed $30,000,000. 
 (iv) Minimum Increases. The request for an increase shall be in a minimum amount of $10,000,000 or such lessor amount as necessary to increase the Revolving Credit Commitments to $80,000,000.

the Agent and the Banks addressing the authorization and execution of the Loan Documents by, and enforceability of the Loan Documents against, the Loan Parties. 

(vi) Notes. The Borrower shall execute and deliver: (1) to each Increasing Bank a replacement Note (except if
such Increasing Bank requests that it not receive a Note) reflecting the new amount of such Increasing Bank’s Revolving Credit Commitment after giving effect to the increase (and the prior Note issued to such Increasing Bank shall be deemed to
be terminated) and (2) to each New Bank a Note (except if such New Bank requests that it not receive a Note) reflecting the amount of such New Banks’ Revolving Credit Commitment. 

(vii) Approval of New Banks. Any New Bank shall be subject to the approval of the Agent (which approval shall not
be unreasonably withheld) and the Borrower (which approval shall not be unreasonably withheld) and shall not be (1) a Borrower or any of the Borrower’s Subsidiaries or Affiliates or (2) a natural person. The Revolving Credit
Commitment of any New Bank shall not be less than $10,000,000. 
 (viii) Increasing Banks. If any portion
of the increase in Revolving Credit Commitments is being provided by one or more Increasing Banks, then such Increasing Banks shall confirm their agreement to increase their Revolving Credit Commitment pursuant to a revolving credit commitment
increase agreement, acceptable to the Agent, signed by the Increasing Banks and Loan Parties and delivered to the Agent at least five (5) Business Days before the Revolving Credit Commitment Increase Date. 

(ix) New Banks—Joinder. If the Borrower desires that one or more New Banks provide all or a portion of such
increase in Revolving Credit Commitments, then each New Bank, the Loan Parties and the Agent shall execute a Bank Joinder in substantially the form of Exhibit 2.11, pursuant to which the New Bank shall join and become a party to this
Agreement and any other Loan Documents as applicable, effective on the Revolving Credit Commitment Increase Date with a Revolving Credit Commitment in the amount set forth in Schedule I to such Bank Joinder. 

2.11.2 Treatment of Outstanding Loans and Letters of Credit. 

2.11.2.1 On the Revolving Credit Commitment Increase Date, the Borrower shall repay all Loans outstanding on the Revolving
Credit Commitment Increase Date, subject to the Borrower’s indemnity obligations under Section 5.6 provided that it may borrow new Loans with a Borrowing Date on the Revolving Credit Commitment Increase Date. Each of the Banks shall
participate in any new Loans made on or after the Revolving Credit Commitment Increase Date in accordance with their respective Ratable Shares after giving effect to the increase in Revolving Credit Commitments contemplated by this
Section 2.11. 
 2.11.2.2 Outstanding Letters of Credit. 

  
 - 34 -









 On the Revolving Credit Commitment Increase Date, each Increasing Bank and
each New Bank: (a) will be deemed to have purchased a participation in each then outstanding Letter of Credit equal to is Ratable Share of each such Letter of Credit and the participation of each other Bank in each such Letter of Credit shall
be adjusted accordingly and (b) will acquire, (and will pay to the Agent, for the account of each Bank, in immediately available funds, an amount equal to) its Ratable Share of all outstanding Participation Advances. 

2.12 Defaulting Banks. 
 Notwithstanding any provision of this Agreement to the contrary, if any Bank becomes a Defaulting Bank, then the following provisions shall apply for so long as such Bank is a Defaulting Bank: 

(i) fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Bank pursuant to
Section 2.3; 
 (ii) the Commitment and outstanding Loans of such Defaulting Bank shall not be included in
determining whether the Required Banks have taken or may take any action hereunder (including any consent to any amendment, waiver or other modification pursuant to Section 11.1); provided, that this clause (ii) shall not apply to the vote
of a Defaulting Bank in the case of an amendment, waiver or other modification requiring the consent of such Bank or each Bank directly affected thereby; 
 (iii) if any Swing Loans are outstanding or any Letter of Credit Obligations exist at the time such Bank becomes a Defaulting Bank, then: 

(a) all or any part of the outstanding Swing Loans and Letter of Credit Obligations of such Defaulting Bank shall be
reallocated among the non-Defaulting Banks in accordance with their respective Ratable Shares but only to the extent that (x) the Revolving Facility Usage does not exceed the total of all non-Defaulting Banks’ Revolving Credit Commitments,
and (y) no Potential Default or Event of Default has occurred and is continuing at such time; 
 (b) if the
reallocation described in clause (a) above cannot, or can only partially, be effected, the Borrower shall within one Business Day following notice by the Agent (x) first, prepay such outstanding Swing Loans, and
(y) second, cash collateralize for the benefit of the Issuing Bank the Borrower’s obligations corresponding to such Defaulting Bank’s Letter of Credit Obligations (after giving effect to any partial reallocation pursuant to
clause (a) above) in a deposit account held at the Agent for so long as such Letter of Credit Obligations are outstanding; 
 (c) if the Borrower cash collateralizes any portion of such Defaulting Bank’s Letter of Credit Obligations pursuant to clause (b) above, the Borrower shall not be required to pay any fees to
such Defaulting Bank pursuant to Section 2.9.2 [Letter of Credit Fees] with respect to such Defaulting Bank’s Letter of Credit Obligations during the period such Defaulting Bank’s Letter of Credit Obligations are cash collateralized;


  
 - 35 -









 (d) if the Letter of Credit Obligations of the non-Defaulting Banks are
reallocated pursuant to clause (a) above, then the fees payable to the Banks pursuant to Section 2.9.2 shall be adjusted in accordance with such non-Defaulting Banks’ Ratable Share; and 

(e) if all or any portion of such Defaulting Bank’s Letter of Credit Obligations are neither reallocated nor cash
collateralized pursuant to clause (a) or (b) above, then, without prejudice to any rights or remedies of the Issuing Bank or any other Bank hereunder, all Letter of Credit Fees payable under Section 2.9.2 with respect to such
Defaulting Bank’s Letter of Credit Obligations shall be payable to the Issuing Bank (and not to such Defaulting Bank) until and to the extent that such Letter of Credit Obligations are reallocated and/or cash collateralized; and 

(f) so long as such Bank is a Defaulting Bank, PNC shall not be required to fund any Swing Loans and the Issuing Bank
shall not be required to issue, amend or increase any Letter of Credit, unless (a) with respect to Letters of Credit, such Issuing Bank is satisfied that the related exposure and the Defaulting Bank’s then outstanding Letter of Credit
Obligations will be 100% covered by the Revolving Credit Commitments of the non-Defaulting Banks and/or cash collateral will be provided by the Borrower in accordance with Section 2.12(iii), and (b) with respect to Swing Loans, the amount
of requested Swing Loans when allocated to non-Defaulting Banks plus outstanding Swing Loans will be 100% covered by the Revolving Credit Commitments of the non-Defaulting Banks. Participating interests in any newly made Swing Loan or any newly
issued or increased Letter of Credit shall be allocated among non-Defaulting Banks in a manner consistent with Section 2.12(iii)(a) (and such Defaulting Bank shall not participate therein). 

If (i) a Bankruptcy Event with respect to a parent company of any Bank shall occur following the date hereof and for so long as such
event shall continue, or (ii) PNC or the Issuing Bank has a good faith belief that any Bank has defaulted in fulfilling its obligations under one or more other agreements in which such Bank commits to extend credit, PNC shall not be required to
fund any Swing Loan and the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless PNC or the Issuing Bank, as the case may be, shall have entered into arrangements with the Borrower or such Bank, satisfactory to
PNC or the Issuing Bank, as the case may be, to defease any risk to it in respect of such Bank hereunder. 
 In the event that
the Agent, the Borrower, PNC and the Issuing Bank agree in writing that a Defaulting Bank has adequately remedied all matters that caused such Bank to be a Defaulting Bank, then the Agent will so notify the parties hereto, and the Ratable Share of
the Swing Loans and Letter of Credit Obligations of the Banks shall be readjusted to reflect the inclusion of such Bank’s Commitment, and on such date such Bank shall purchase at par such of the Loans of the other Banks (other than Swing Loans)
as the Agent shall determine may be necessary in order for such Bank to hold such Loans in accordance with its Ratable Share.

 4. INTEREST RATES 
 4.1 Interest Rate Options. 

The Borrower shall pay interest in respect of the outstanding unpaid principal amount of the Loans as selected by it from
the Base Rate Option or Euro-Rate Option set forth below applicable to the Loans, it being understood that, subject to the provisions of this Agreement, the Borrower may select different Interest Rate Options and different Interest Periods to apply
simultaneously to the Loans comprising different Borrowing Tranches and may convert to or renew one or more Interest Rate Options 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 eight (8) Borrowing Tranches in the aggregate among all of the Loans and provided further that only the Revolving Credit Base Rate Option shall apply to the Swing 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. 

4.1.1. Revolving Credit Interest Rate Options. 

The Borrower shall have the right to select from the following Interest Rate Options applicable to the Revolving Credit
Loans and Swing Loans (subject to the provisions above regarding Swing Loans): 
 (i) Revolving Credit Base
Rate Option: A fluctuating rate per annum (computed on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed) equal to the Base Rate plus the Applicable Margin, such interest rate to change automatically from time
to time effective as of the effective date of each change in the Base Rate; or 
 (ii) Revolving Credit
Euro-Rate Option: 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. 
 4.1.2. [Reserved]. 
 4.1.3. Initial Interest Rates

 Notwithstanding any other provision of this Agreement (including Schedule 1.1.1(A)), the Applicable Margin
shall be at Level I on Schedule 1.1.1(A) until the Adjustment Date following receipt by the Agent of Borrower’s Compliance Certificate for the fiscal quarter ended June 30, 2011. 

  
 - 37 -









 4.1.4. Rate Quotations. 

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. 

4.2 Interest Periods. 
 At any time when the Borrower shall select, convert to or renew a Euro-Rate Option, the Borrower shall notify the Agent thereof at least three (3) Business Days prior to the effective date of such
Euro-Rate Option by delivering a Loan Request. The notice shall specify an Interest Period during which such Interest Rate Option shall apply. Notwithstanding the preceding sentence, the following provisions shall apply to any selection of, renewal
of, or conversion to a Euro-Rate Option: 
 4.2.1. Amount of Borrowing Tranche. 

each Borrowing Tranche of Euro-Rate Loans shall be in integral multiples of $500,000 and not less than $500,000;

 4.2.2. Renewals. 

in the case of the renewal of a Euro-Rate Option 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. 
 4.3
Interest After Default. 
 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: 
 4.3.1. Letter of Credit Fees,
Interest Rate. 
 the Letter of Credit Fees and the rate of interest for each Loan otherwise applicable
pursuant to Section 2.9.2 [Letter of Credit Fees] or Section 4.1 [Interest Rate Options], respectively, shall be increased by 2.00% per annum; and 

4.3.2. Other Obligations. 
 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 Revolving Credit Base Rate Option plus an
additional 2.00% per annum from the time such Obligation becomes due and payable and until it is paid in full. 

  
 - 38 -









 4.3.3. Acknowledgment. 

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. 
 4.4 Euro-Rate Unascertainable; Illegality; Increased Costs; Deposits Not Available. 

4.4.1. Unascertainable. 
 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 eurodollar market relating to the Euro-Rate, 
 the Agent shall have the rights specified in Section 4.4.3. 
 4.4.2. Illegality; Increased Costs; Deposits Not Available. 

If at any time any Bank shall have determined that: 

(i) the making, maintenance or funding of any Loan to which a Euro-Rate Option 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 Option 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 Option 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. 

  
 - 39 -









 4.4.3. Agent’s and Bank’s Rights. 

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, convert to or renew a Euro-Rate Option 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, conversion to or renewal of a Euro-Rate Option and such Interest Rate Option has not yet gone into effect, such
notification shall be deemed to provide for selection of, conversion to or renewal of the Base Rate Option otherwise available 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 Option applies, on the date specified in such notice either convert such Loan to the Base Rate
Option otherwise available 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 Base Rate Option otherwise available with respect to such Loan upon such specified date. 
 4.5 Selection of Interest
Rate Options. 
 If the Borrower fails to select a new Interest Period to apply to any Borrowing Tranche of
Loans under the Euro-Rate Option 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 converted
such Borrowing Tranche to the Revolving Credit Base Rate Option commencing upon the last day of the existing Interest Period. 

5. PAYMENTS 
 5.1 Payments. 
 All payments and prepayments to be made in
respect of principal, interest, Commitment Fees, Letter of Credit Fees, Agent’s Fee 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 

  
 - 40 -









 
Principal Office for the account of PNC Bank with respect to the Swing Loans and for the ratable accounts of the Banks with respect to the Revolving Credit Loans in U.S. Dollars 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.” 
 5.2 Pro Rata Treatment of
Banks. 
 Each borrowing shall be allocated to each Bank according to its Ratable Share, and each selection
of, conversion to or renewal of any Interest Rate Option and each payment or prepayment by the Borrower with respect to principal, interest, Commitment Fees, Letter of Credit Fees, or other fees (except for the Agent’s Fee) 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.
Notwithstanding any of the foregoing, each borrowing or payment or prepayment by the Borrower of principal, interest, fees or other amounts from the Borrower with respect to Swing Loans shall be made by or to PNC Bank according to Section 2.

 5.3 Interest Payment Dates. 
 Interest on Loans to which the Base Rate Option applies (including Swing Loans) shall be due and 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. Interest on Loans to which the Euro-Rate Option applies shall be due and payable on the last day of each Interest Period for those Loans and, if such Interest Period is longer than three
(3) Months, also on the 90th day of such Interest Period. 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). 

  
 - 41 -









 5.4 Voluntary Prepayments. 

5.4.1. Right to Prepay. 
 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): 
 (i) at any time with respect to any Loan to which the Base Rate Option applies,

 (ii) on the last day of the applicable Interest Period with respect to Loans to which a Euro-Rate Option
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 Option 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 or no later than 2:00 p.m., Pittsburgh time, on the
date of prepayment of Swing 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 Swing Loans; and 
 (z) the total principal amount of such
prepayment, which shall not be less than $100,000 for any Swing Loan or $500,000 for any Revolving Credit. 
 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 Base Rate Option 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 Base Rate Option applies, then to Loans to which the Euro-Rate Option applies. Any prepayment hereunder shall be subject to the Borrower’s Obligation to indemnify the Banks under Section 5.8 [Indemnity]. 

  
 - 42 -









 5.4.2. Replacement of a Bank. 

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] and provided that all Letters of Credit have expired or been terminated or replaced. 
 5.4.3. Change of Lending Office. 
 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 or Letters of Credit 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. 
 5.5 Reserved.

 5.6 Increased Costs. 
 5.6.1 Increased Costs Generally. If any Change in Law shall: 

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

(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, 

  
 - 43 -









 
interest, Commitment Fees, 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, the Issuing Bank or the London interbank market any other condition, cost or expense affecting
this Agreement or any Loan under the Euro-Rate Option made by such Bank or any Letter of Credit or participation therein; 
 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 Option (or of maintaining its obligation to make any such Loan), or to increase the cost to such Bank or the Issuing Bank of
participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Bank or the Issuing Bank hereunder
(whether of principal, interest or any other amount) then, upon request of such Bank or the Issuing Bank, the Borrower will pay to such Bank or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Bank or
the Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered. 
 5.6.2.
Capital Requirements. 
 If any Bank or the Issuing Bank determines that any Change in Law affecting such
Bank or the Issuing Bank or any lending office of such Bank or such Bank’s or the Issuing 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 or the
Issuing Bank’s capital or on the capital of such Bank’s or the Issuing Bank’s holding company, if any, as a consequence of this Agreement, the Commitments of such Bank or the Loans made by, or participations in Letters of Credit held
by, such Bank, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Bank or the Issuing Bank or such Bank’s or the Issuing Bank’s holding company could have achieved but for such Change in Law (taking into
consideration such Bank’s or the Issuing Bank’s policies and the policies of such Bank’s or the Issuing Bank’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Bank or the
Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Bank or the Issuing Bank or such Bank’s or the Issuing Bank’s holding company for any such reduction suffered. 

5.6.3 Certificates for Reimbursement; Repayment of Outstanding Loans; Borrowing of New Loans. A certificate of a
Bank or the Issuing Bank setting forth the amount or amounts necessary to compensate such Bank or the Issuing Bank or its holding company, as the case may be, as specified in Sections 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 or the Issuing Bank, as the case may be,
the amount shown as due on any such certificate within ten (10) days after receipt thereof. 
 5.6.4
Delay in Requests. Failure or delay on the part of any Bank or the Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of 

  
 - 44 -









 
such Bank’s or the Issuing Bank’s right to demand such compensation, provided that the Borrower shall not be required to compensate a Bank or the Issuing 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 or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or
reductions and of such Bank’s or the Issuing Bank’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the six (6) month period referred
to above shall be extended to include the period of retroactive effect thereof). 
 5.7 Settlement Date Procedures. In
order to minimize the transfer of funds between the Banks and the Agent, the Borrower may borrow, repay and reborrow Swing Loans and PNC may make Swing Loans as provided in Section 2.5.2 hereof during the period between Settlement Dates. The
Agent shall notify each Bank of its Ratable Share of the total of the Revolving Credit Loans and the Swing Loans (each a “Required Share”). On such Settlement Date, each Bank shall pay to the Agent the amount equal to the difference
between its Required Share and its Revolving Credit Loans, and the Agent shall pay to each Bank its Ratable Share of all payments made by the Borrower to the Agent with respect to the Revolving Credit Loans. The Agent shall also effect settlement in
accordance with the foregoing sentence on the proposed Borrowing Dates for Revolving Credit Loans and on the dates in which any optional or mandatory prepayments are made hereunder and may at its option effect settlement on any other Business Day.
These settlement procedures are established solely as a matter of administrative convenience, and nothing contained in this Section 5.7 shall relieve the Banks of their obligations to fund Revolving Credit Loans on dates other than a Settlement
Date pursuant to Section 2.5.2. The Agent may at any time at its option for any reason whatsoever require each Bank to pay immediately to the Agent such Bank’s Ratable Share of the outstanding Revolving Credit Loans and each Bank may at
any time require the Agent to pay immediately to such Bank its Ratable Share of all payments made by the Borrower to the Agent with respect to the Revolving Credit Loans. 
 5.8 Indemnity. 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, conversion or renewal of any Loan to which a Euro-Rate Option 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; Swing Loan Requests] or Section 4.2 [Interest Periods] or notice relating to prepayments under Section 5.4 [Voluntary Prepayments], or 

  
 - 45 -









 (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, Commitment Fee 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.

prepared in accordance with GAAP consistently applied.

 6.1.10.2 Margin Stock. 

None of the Loan Parties or any Subsidiaries of any Loan Party 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 Loan Parties or any Subsidiary of any Loan Party holds or intends to hold
margin stock in such amounts that more than 25% of the reasonable value of the assets of any Loan Party or Subsidiary of any Loan Party are or will be represented by margin stock.

Default. 
 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 or issue Letters of Credit, as the case may be, and the Agent may, and upon the request of the Required Banks, shall (i) by written notice to the Borrower,
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, and (ii) require the Borrower to, and
the Borrower shall thereupon, deposit in a non-interest-bearing account with the Agent, as cash collateral for its Obligations under the Loan Documents, an amount equal to the maximum amount currently or at any time thereafter available to be drawn
on all outstanding Letters of Credit, and the Borrower hereby pledges to the Agent and 

  
 - 76 -









 
the Banks, and grants to the Agent and the Banks a security interest in, all such cash as security for such Obligations. Upon the curing of all existing Events of Default to the satisfaction of
the Required Banks, the Agent shall return such cash collateral to the Borrower; and 
 9.2.2. Bankruptcy,
Insolvency or Reorganization Proceedings. 
 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

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 
 9.2.4. Suits, Actions, Proceedings.

 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 

  
 - 77 -









 
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 

9.2.5. Application of Proceeds; Set Off Sharing. 

9.2.5.1 Application of Proceeds. 

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 any Loan Party 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 or a Bank-Provided Interest Rate Hedge and Indebtedness under any Other Bank Provided Financial Services Product, whether of principal, interest, fees, expenses or otherwise, in such manner as the Agent
may determine in its discretion; and 
 (iii) the balance, if any, as required by Law. 

9.2.5.2 Set Off Sharing. 
 All rights of set off existing under any Loan Document shall secure ratably and on a pari passu basis (i) the Obligations in favor of the Agent and the Banks hereunder and (ii) the Obligations
incurred by any of the Loan Parties in favor of any Bank which provides a Bank-Provided Interest Rate Hedge (the “IRH Provider”). The Agent shall be deemed to serve as the collateral agent (the “Collateral Agent”) for the IRH
Provider 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. No IRH Provider (except in its capacity as a Bank hereunder) shall be entitled or have the power to direct or instruct the Collateral Agent on
any such matters or to control or direct in any manner the maintenance or disposition of such proceeds. 

  
 - 78 -









 9.2.6. Other Rights and Remedies. 

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. 
 10. THE
AGENT 
 10.1 Appointment. 
 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. 
 10.2 Delegation of Duties. 
 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. 

10.3 Nature of Duties; Independent Credit Investigation. 

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


  
 - 79 -









 
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. 
 10.4 Actions in Discretion of Agent; Instructions From the
Banks. 
 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. 
 10.5 Reimbursement and Indemnification of Agent by
the Borrower. 
 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 

  
 - 80 -









 
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. 

10.6 Exculpatory Provisions; Limitation of Liability. 

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 an 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. 

  
 - 81 -









 10.7 Reimbursement and Indemnification of Agent by Banks. 

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. 
 10.8 Reliance by Agent. 

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. 
 10.9
Notice of Default. 
 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.” 
 10.10 Notices. 
 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


  
 - 82 -









 
promptly upon receipt thereof. The Agent shall promptly notify the Borrower and the other Banks of each change in the Base Rate and the effective date thereof. 

10.11 Banks in Their Individual Capacities; Agent in its Individual Capacity. 

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. 
 10.12 Holders of Notes. 
 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. 

10.13 Equalization of Banks. 
 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 

  
 - 83 -









 
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. 

10.14 Successor Agent. 
 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. 
 10.15 Agent’s Fee. 

The Borrower shall pay to the Agent a nonrefundable fee (the “Agent’s Fee”) under the terms of a
letter (the “Agent’s Letter”) between the Borrower and Agent, as amended from time to time, provided that no Agent’s Fee shall be payable unless there are two or more Banks. No Agent Fee Letter will be in place on the
Closing Date. If at any time after the Closing Date there are two or more Banks, and as a condition precedent to the joinder of a Bank under Section 2.11 of this Agreement, the Agent and the Borrower shall negotiate and enter into an
Agent’s Letter with terms acceptable to the Agent. 
 10.16 Availability of Funds. 

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 

  
 - 84 -









 
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. 
 10.17 Calculations. 
 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. 
 10.18 No Reliance on Agent’s Customer Identification Program. 

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. 
 10.19
Beneficiaries. 
 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


  
 - 85 -









 
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. 
 11. MISCELLANEOUS 
 11.1 Modifications, Amendments or Waivers. 
 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: 
 11.1.1. Increase of Commitment; Extension of Expiration Date. 

Extend the Expiration Date, or subject to the provisions of Section 2.11 hereof, increase the amount of the Revolving
Credit Commitment of any Bank hereunder; 
 11.1.2. Extension of Payment; Reduction of Principal Interest or
Fees; Modification of Terms of Payment. 
 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), the Commitment Fee 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 the Commitment Fee or any other fee payable to any Bank, or otherwise
affect the terms of payment of the principal of or interest of any Loan, the Commitment Fee or any other fee payable to any Bank; or 
 11.1.3. [Reserved].

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 or as the issuer of Letters of Credit
shall be effective without the written consent of the Agent. 
 11.2 No Implied Waivers; Cumulative Remedies; Writing
Required. 
 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. 
 11.3 Reimbursement and Indemnification of Banks by the Borrower; Taxes. 
 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 

  
 - 87 -









 
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. 

11.4 Holidays. 
 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 Option) 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. 
 11.5 Funding by Branch, Subsidiary or Affiliate. 
 11.5.1.
Notional Funding. 
 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 Option 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.

 11.5.2. Actual Funding. 

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 

  
 - 88 -









 
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. 
 11.6 Notices. 
 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: 
 (i) In the case of hand-delivery, when delivered;

 (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; 

(v) In the case of electronic transmission, when actually received; 

(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 

  
 - 89 -









 (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. 
 11.7 Severability. 

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

Each Letter of Credit and Section 2.9 [Letter of Credit Subfacility] shall be subject to the Uniform Customs
and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500, as the same may be revised or amended from time to time, and to the extent not inconsistent therewith, the internal laws of the
Commonwealth of Pennsylvania without regard to its conflict of laws principles, and the balance of 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. 
 11.9 Prior Understanding. 
 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. 
 11.10 Duration; Survival. 

All representations and warranties of the Loan Parties contained herein or made in connection herewith shall survive the
making of Loans and issuance of Letters of Credit 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, issuance of Letters of Credit, 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 may borrow or request Letters of Credit hereunder and until termination of the Commitments and payment in full of the Loans and expiration or termination of all Letters of Credit. 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 

  
 - 90 -









 
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, expiration or termination of the Letters of Credit and termination of the Commitments. 
 11.11 Successors and Assigns. 
 (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 $5,000,000 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.], or 11.1.3 [Release of Guarantor]), all of such Bank’s
obligations under this Agreement or any other Loan Document shall remain unchanged, and all amounts payable by any Loan Party 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 any Loan Party or its Subsidiaries and any other information concerning any Loan Party 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]. 

  
 - 91 -









 (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. 

11.12 Confidentiality. 
 11.12.1. General. 
 The Agent and the Banks each agree to
keep confidential all information obtained from any Loan Party or its Subsidiaries which is nonpublic and confidential or proprietary in nature (including any information the Borrower 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 agreement of such Persons to maintain the 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 Borrower 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, Letters of Credit and transactions contemplated hereby.

 11.12.2. Sharing Information With Affiliates of the Banks. 

Each Loan Party acknowledges that from time to time financial advisory, investment banking and other services may be

 - 92 -









 
Bank to share any information delivered to such Bank by such Loan Party and its Subsidiaries pursuant to this Agreement, or in connection with the decision of such Bank to enter into this
Agreement, to any such Subsidiary or Affiliate of such Bank, it being understood that any such Subsidiary or affiliate of any Bank receiving such information shall be bound by the provisions of Section 11.12.1 as if it were a Bank
hereunder. Such Authorization shall survive the repayment of the Loans and other Obligations and the termination of the Commitments. 
 11.13 Counterparts. 
 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. 

11.14 Agent’s or Bank’s Consent. 

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. 
 11.15 Exceptions. 

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. 
 11.16 CONSENT TO FORUM; WAIVER OF JURY TRIAL. 

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

OF OR RELATED TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT TO THE FULL EXTENT PERMITTED BY LAW. 
 11.17 Certifications From Banks and Participants 
 11.17.1.
Tax Withholding. 
 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 Borrower 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 Borrower 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 Borrower 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 Borrower 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 Borrower 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. 

  
 - 94 -









 11.17.2. USA Patriot Act. 

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. 
 11.18 Joinder of Guarantors.

 Any Subsidiary of the Borrower which is required to join this Agreement as a Guarantor pursuant to
Section 8.2.9 [Subsidiaries, Partnerships and Joint Ventures] or Section 8.2.15 [Inactive Subsidiaries] shall execute and deliver to the Agent (i) a Guarantor Joinder in substantially the form attached hereto as Exhibit
1.1(G)(1) pursuant to which it shall join as a Guarantor to each of the documents to which the Guarantors are parties; and (ii) documents in the forms described in Section 7.1 [First Loans] modified as appropriate
to relate to such Subsidiary. If such joinder is pursuant to Section 8.2.9 [Subsidiaries, Partnerships and Joint Ventures], the Loan Parties shall deliver such Guarantor Joinder and related documents to the Agent within five (5) Business
Days after the date of the filing of such Subsidiary’s articles of incorporation if the Subsidiary is a corporation, the date of the filing of its certificate of limited partnership if it is a limited partnership or the date of its organization
if it is an entity other than a limited partnership or corporation.

Banks determine that (i) the Leverage Ratio as calculated by the Borrower as of any applicable date was inaccurate and (ii) a proper calculation of the Leverage Ratio would have resulted in higher pricing











	 	 
for such period, the Borrower shall immediately and retroactively be obligated to pay to the Agent for the account of the applicable Banks, promptly on demand by the Agent (or, after the
occurrence of an actual or deemed entry of an order for relief with respect to the Borrower under the Bankruptcy Code of the United States, automatically and without further action by the Agent, any Bank or the Issuing Bank), an amount equal to the
excess of the amount of interest and fees that should have been paid for such period over the amount of interest and fees actually paid for such period. This paragraph shall not limit the rights of the Agent, any Bank or the Issuing Bank, as the
case may be, under Section 2.9 [Letter of Credit Subfacility] or 4.3 [Interest After Default] or Article 9 [Default]. The Borrower’s obligations under this paragraph shall survive the termination of the Commitments and the repayment of all
other Obligations hereunder.

 EXHIBIT 1.1(G)(2) 

CONTINUING AGREEMENT OF GUARANTY AND SURETYSHIP 

THIS CONTINUING AGREEMENT OF GUARANTY AND SURETYSHIP (this “Guaranty”), dated as of this 15th day of June, 2011, 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 June 15, 2011, by and among II-VI 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 any Bank which provides a Bank Provided Interest Rate Hedge or any provider of Other Bank
Provided Financial Service Products, 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 Bank Provided Interest Rate Hedge, (iv) any Other Bank Provided Financial Service Product, and (v) the Second Amended and Restated Letter Agreement dated September 25, 2002, as amended, supplemented
or otherwise modified from time to time, between PNC Bank, National Association and II-VI Japan Incorporated, a subsidiary of the Borrower with respect to the Rate Protection Term Loan (as defined in the Credit Agreement), whether for principal,
interest, fees, indemnities, expenses, or otherwise, and all renewals, extensions, amendments, refinancings 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 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 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 pursuant to Section 8.2.9 [Subsidiaries, Partnerships and Joint Ventures] of the Credit Agreement 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, the expiration of all Letters of
Credit 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 and all Letters of Credit have expired. 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 (except as expressly permitted in the Intercompany Subordination Agreement), 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. 
 8. Reserved. 
 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. 
 11. Setoff, Default Payments by Borrower. 

(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. 
 14. Governing Law; Submission to Jurisdiction; Waiver of Jury Trial. 
 (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. 

(b) Certain Waivers. Each Guarantor hereby irrevocably: 

(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. Each Guarantor hereby appoints the process agent identified below (the “Process Agent”) as its agent to
receive on behalf of such party and its respective property service of copies of the summons and complaint and any other process which may be served in any action or proceeding. Such service may be made by mailing or delivering a copy of such
process to the Guarantor in care of the Process Agent at the Process Agent’s address, and each Guarantor hereby authorizes and directs the Process Agent to receive such service on its behalf. Each Guarantor agrees that a final judgment in any
such action or proceeding shall be conclusive and may be enforced in other jurisdictions (or any political subdivision thereof) by suit on the judgment or in any other manner provided at law. Each Guarantor further agrees that it shall, for so long
as any commitment or any obligation of any Loan Party to any Bank remains outstanding, continue to retain Process Agent for the purposes set forth in this Section 14. The Process Agent is the II-VI Incorporated, with an office on the date
hereof as set forth in the Credit Agreement. The Process Agent hereby accepts the appointment of Process Agent by the Companies and agrees to act as Process Agent on behalf of the Companies; 

(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. 

15. Severability; Modification to Conform to 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. 

17. Joint and Several Obligations. 
 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. 
 18. Receipt of Credit Agreement, Other Loan Documents, Benefits. 

(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. 

19. Miscellaneous. 
 (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.

 EXHIBIT 1.1(I)(2) 

INTERCOMPANY SUBORDINATION AGREEMENT 
 THIS INTERCOMPANY SUBORDINATION AGREEMENT (this “Agreement”), dated June 15, 2011, is made by and among the entities listed on the signature page hereto (or subsequently joining this
Agreement) (each being individually referred to herein as a “Company” and collectively as the “Companies”). 

WITNESSETH THAT: 

WHEREAS, each capitalized term used herein shall, unless otherwise defined herein, have the meaning specified in the Credit Agreement,
dated of even date herewith, by and among II-VI Incorporated, a Pennsylvania corporation (the “Borrower”), the Guarantors party thereto, PNC Bank, National Association (“PNC”), various other financial institutions which are now
or hereafter become a party thereto (such other financial institution are each, a “Bank” and collectively, the “Banks”) and PNC, as agent for the Banks (in such capacity, the “Agent”) (as it may be hereafter amended,
restated, supplemented or otherwise modified from time to time, the “Credit Agreement”); and 
 WHEREAS, pursuant to
the Credit Agreement and the other Loan Documents, the Banks intend to make Loans to the Borrower; and 
 WHEREAS, the Companies
are or may become indebted to each other (the Indebtedness of each of the Companies to any other Company, now existing or hereafter incurred (whether created directly or acquired by assignment or otherwise), and interest and premiums, if any,
thereon and other amounts payable in respect thereof are hereinafter collectively referred to as the “Intercompany Indebtedness”); and 
 WHEREAS, the obligations of the Banks to maintain the Commitments and make Loans to the Borrower from time to time are subject to the condition, among others, that the Companies subordinate the
Intercompany Indebtedness to the Indebtedness and all other Obligations of the Borrower or any other Company to the Agent or the Banks or any Affiliate of any Bank pursuant to the Credit Agreement, the Rate Protection Agreement (Japan) (as defined
in the Credit Agreement or the other Loan Documents (collectively, the “Senior Debt”) in the manner set forth herein. 

NOW, THEREFORE, intending to be legally bound hereby, the parties hereto covenant and agree as follows: 

1. Intercompany Indebtedness Subordinated to Senior Debt. The recitals set forth above are hereby incorporated by reference. All
Intercompany Indebtedness shall be subordinate and subject in right of payment to the prior indefeasible payment in full of all Senior Debt pursuant to the provisions contained herein. 







 2. Payment Over of Proceeds Upon Dissolution, Etc. Upon any distribution of assets of
any Company in the event of (a) any insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to any such Company or to its creditors, as
such, or to its assets, or (b) any liquidation, dissolution or other winding up of any such Company, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or (c) any assignment for the benefit of creditors
or any marshalling of assets and liabilities of any such Company (a Company distributing assets as set forth herein being referred to in such capacity as a “Distributing Company”), then and in any such event, the Agent shall be entitled to
receive, for the benefit of the Agent and the Banks as their respective interests may appear, indefeasible payment in full of all amounts due or to become due (whether or not an Event of Default has occurred under the terms of the Loan Documents or
the Senior Debt has been declared due and payable prior to the date on which it would otherwise have become due and payable) on or in respect of any and all Senior Debt before the holder of any Intercompany Indebtedness owed by the Distributing
Company is entitled to receive any payment on account of the principal of or interest on such Intercompany Indebtedness, and to that end, the Agent shall be entitled to receive, for application to the payment of the Senior Debt, any payment or
distribution of any kind or character, whether in cash, property or securities, which may be payable or deliverable in respect of the Intercompany Indebtedness owed by the Distributing Company in any such case, proceeding, dissolution, liquidation
or other winding up event. 
 If, notwithstanding the foregoing provisions of this Section, a Company which is owed Intercompany
Indebtedness by a Distributing Company shall have received any payment or distribution of assets from the Distributing Company of any kind or character, whether in cash, property or securities, then and in such event such payment or distribution
shall be held in trust for the benefit of the Agent and the Banks as their respective interests may appear, shall be segregated from other funds and property held by such Company, and shall be forthwith paid over to the Agent in the same form as so
received (with any necessary endorsement) to be applied (in the case of cash) to or held as collateral (in the case of noncash property or securities) for the payment or prepayment of the Senior Debt in accordance with the terms of the Credit
Agreement. 
 3. No Commencement of Any Proceeding. Each Company agrees that, so long as the Senior Debt shall remain
unpaid, it will not commence, or join with any creditor other than the Banks and the Agent in commencing any proceeding referred to in Section 2 against any other Company which owes it any Intercompany Indebtedness. 

4. Prior Payment of Senior Debt Upon Acceleration of Intercompany Indebtedness. If any portion of the Intercompany Indebtedness
owed by any Company becomes or is declared due and payable before its stated maturity and without consent for compromise, restructure or forbearance or similar accommodation by Agent as provided in Section 10, then and in such event the Agent
and the Banks shall be entitled to receive indefeasible payment in full of all amounts due and to become due on or in respect of the Senior Debt (whether or not an Event of Default has occurred under the terms of the Loan Documents or the Senior
Debt has been declared due and payable prior to the date on which it would otherwise have become due and payable) before the holder of any such Intercompany Indebtedness is entitled to receive any payment thereon. 







 If, notwithstanding the foregoing, any Company shall make any payment of Intercompany
Indebtedness prohibited by the foregoing provisions of this Section, such payment shall be paid over and delivered forthwith to the Agent, for the benefit of the Agent and the Banks as their respective interests may appear. 

The provisions of this Section shall not apply to any payment with respect to which Section 2 hereof would be applicable.

 5. No Payment When Senior Debt in Default. If any Event of Default shall have occurred and be continuing, or such an
Event of Default or Potential Default would result from or exist after giving effect to a payment with respect to any portion of the Intercompany Indebtedness, unless the Required Banks shall have consented to or waived the same, so long as any of
the Senior Debt shall remain outstanding, no payment shall be made by any Company owing such Intercompany Indebtedness on account of principal or interest on any portion of the Intercompany Indebtedness. 

If, notwithstanding the foregoing, any Company shall make any payment of the Intercompany Indebtedness to another Company prohibited by
the foregoing provisions of this Section, such payment shall be paid over and delivered forthwith to the Agent, for the benefit of the Agent and the Banks as their respective interests may appear. 

The provisions of this Section shall not apply to any payment with respect to which Section 2 hereof would be applicable.

 6. Payment Permitted if No Default. Nothing contained in this Agreement shall prevent any of the Companies, at any
time except during the pendency of any of the conditions described in Sections 2, 4 and 5, from making payments at any time of principal of or interest on any portion of the Intercompany Indebtedness, or the retention thereof by any of the Companies
of any money deposited with them for the payment of or on account of the principal of or interest on the Intercompany Indebtedness. 
 7. Rights of Subrogation. Each Company agrees that no payment or distribution to the Agent or the Banks pursuant to the provisions of this Agreement shall entitle it to exercise any rights of
subrogation in respect thereof until the Senior Debt shall have been indefeasibly paid in full and the Commitments shall have terminated. 
 8. Instruments Evidencing Intercompany Indebtedness. Each Company shall cause each instrument which now or hereafter evidences all or a portion of the Intercompany Indebtedness to be conspicuously
marked as follows: 
 “This instrument is subject to the terms of an Intercompany Subordination Agreement
dated June 15, 2011 in favor of PNC Bank, National Association, as Agent for the Banks referred to therein, which Intercompany Subordination Agreement is incorporated herein by reference. Notwithstanding any contrary statement contained in the
within instrument, no payment on account of the principal thereof or interest thereon shall become due or payable except in accordance with the express terms of said Intercompany Subordination Agreement.” 







 Each Company will further mark its books of account in such a manner as shall be effective to give proper
notice to the effect of this Agreement. 
 9. Agreement Solely to Define Relative Rights. The purpose of this Agreement
is solely to define the relative rights of the Companies, on the one hand, and the Agent and the Banks, on the other hand. Nothing contained in this Agreement is intended to or shall impair, as between any of the Companies and their creditors other
than the Agent and the Banks, the obligation of the Companies to each other to pay the principal of and interest on the Intercompany Indebtedness as and when the same shall become due and payable in accordance with its terms, or is intended to or
shall affect the relative rights among the Companies and their creditors other than the Agent and the Banks, nor shall anything herein prevent any of the Companies from exercising all remedies otherwise permitted by applicable Law upon default under
any agreement pursuant to which the Intercompany Indebtedness is created, subject to the rights, if any, under this Agreement of the Agent and the Banks to receive cash, property or securities otherwise payable or deliverable with respect to the
Intercompany Indebtedness. 
 10. No Implied Waivers of Subordination. No right of the Agent or any Bank to enforce
subordination, as herein provided, shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of any Company or by any act or failure to act by the Agent or any Bank, or by any non-compliance by any Company with
the terms, provisions and covenants of any agreement pursuant to which the Intercompany Indebtedness is created, regardless of any knowledge thereof the Agent or any Bank may have or be otherwise charged with. Each Company by its acceptance hereof
shall agree that, so long as there is Senior Debt outstanding or Commitments in effect under the Credit Agreement, such Company shall not agree to sell, assign, pledge, encumber or otherwise dispose of, or to compromise, restructure or grant
forbearance or similar accommodation, the obligations of the other Companies with respect to their Intercompany Indebtedness, other than by means of payment of such Intercompany Indebtedness according to its terms, without the prior written consent
of the Agent. 
 Without in any way limiting the generality of the foregoing paragraph, the Agent or any of the Banks may, at
any time and from time to time, without the consent of or notice to the Companies except the Borrower to the extent provided in the Credit Agreement, without incurring responsibility to the Companies and without impairing or releasing the
subordination provided in this Agreement or the obligations hereunder of the Companies to the Agent and the Banks, do any one or more of the following: (i) change the manner, place or terms of payment, or extend the time of payment, renew or
alter the Senior Debt or otherwise amend or supplement the Senior Debt or the Loan Documents; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing the Senior Debt; (iii) release any
Person liable in any manner for the payment or collection of the Senior Debt; and (iv) exercise or refrain from exercising any rights against any of the Companies and any other Person. 

11. Additional Subsidiaries. The Companies covenant and agree that they shall cause Subsidiaries created or acquired after the
date of this Agreement, and any other Subsidiaries required to join this Agreement pursuant to Section 8.2.8 or otherwise under the Credit Agreement, to execute a Joinder in the form of Exhibit 1.1(G)(1) to the Credit Agreement, whereby such
Subsidiary joins this Agreement and subordinates all Indebtedness owed to any 







 
such Subsidiary by any of the Companies or other Subsidiaries hereafter created or acquired to the Senior Debt. 
 12. Continuing Force and Effect. This Agreement shall continue in force for so long as any portion of the Senior Debt remains unpaid and any Commitments under the Credit Agreement remain
outstanding, it being contemplated that this Agreement be of a continuing nature. 
 13. Modification, Amendments or
Waivers. Any and all agreements amending or changing any provision of this Agreement or the rights of the Agent or the Banks hereunder, and any and all waivers or consents to Events of Default or other departures from the due performance of the
Companies hereunder, shall be made only by written agreement, waiver or consent signed by the Agent, acting on behalf of all the Banks, with the written consent of the Required Banks, any such agreement, waiver or consent made with such written
consent being effective to bind all the Banks. 
 14. Expenses. The Companies unconditionally and jointly and severally
agree upon demand to pay to the Agent and the Banks the amount of any and all reasonable and necessary out-of-pocket costs, expenses and disbursements for which reimbursement is customarily obtained, including reasonable fees and expenses of

Companies to perform or observe any of the provisions hereof. 
 15. Severability. The provisions of this Agreement are
intended to be severable. If any provision of this Agreement shall be held invalid or unenforceable in whole or in part in any jurisdiction, such provision shall, as to such jurisdiction, be ineffective to the extent of such invalidity or

assigns. The duties and obligations of the Companies may not be delegated or transferred by the Companies without the written consent of the Required Banks and any such delegation or transfer without such consent shall be null and void. Except to
the extent otherwise required by the context of this Agreement, the word “Banks” when used herein shall include, without limitation, any holder of a Note or an assignment of rights therein originally issued to a Bank under the Credit
Agreement, and each such holder of a Note or assignment shall have the benefits of this Agreement to the same extent as if such holder had originally been a Bank under the Credit Agreement. 







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

19. Attorneys-in-Fact. Each of the Companies hereby authorizes and empowers the Agent, at its election and in the name of either
itself, for the benefit of the Agent and the Banks as their respective interests may appear, or in the name of each such Company as is owed Intercompany Indebtedness, to execute and file proofs and documents and take any other action the Agent may
deem advisable to completely protect the Agent’s and the Banks’ interests in the Intercompany Indebtedness and their right of enforcement thereof, and to that end each of the Companies hereby irrevocably makes, constitutes and appoints the
Agent, its officers, employees and agents, or any of them, with full power of substitution, as the true and lawful attorney-in-fact and agent of such Company, and with full power for such Company, and in the name, place and stead of such Company for
the purpose of carrying out the provisions of this Agreement, and taking any action and executing, delivering, filing and recording any instruments which the Agent may deem necessary or advisable to accomplish the purposes hereof, which power of
attorney, being given for security, is coupled with an interest and is irrevocable. Each Company hereby ratifies and confirms, and agrees to ratify and confirm, all action taken by the Agent, its officers, employees or agents pursuant to the
foregoing power of attorney. 
 20. Application of Payments. In the event any payments are received by the Agent under
the terms of this Agreement for application to the Senior Debt at any time when the Senior Debt has not been declared due and payable and prior to the date on which it would otherwise become due and payable, such payment shall constitute a voluntary
prepayment of the Senior Debt for all purposes under the Credit Agreement. 
 21. Remedies. In the event of a breach by
any of the Companies in the performance of any of the terms of this Agreement, the Agent, on behalf of the Banks, may demand specific performance of this Agreement and seek injunctive relief and may exercise any other remedy available at law or in
equity, it being recognized that the remedies of the Agent on behalf of the Banks at law may not fully compensate the Agent on behalf of the Banks for the damages they may suffer in the event of a breach hereof. 

22. Consent to Jurisdiction, Waiver of Jury Trial. Each of the Companies hereby irrevocably consents to the non-exclusive
jurisdiction of the Court of Common Pleas of Allegheny County, Pennsylvania and the United States District Court for the Western District of Pennsylvania, 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 the Companies at the addresses referred to in Section 23 hereof and service so made shall be deemed to be completed upon actual receipt thereof. Each of the Companies 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 EACH OF THE COMPANIES WAIVES TRIAL BY JURY IN ANY ACTION OR PROCEEDING
WITH RESPECT TO THIS AGREEMENT TO THE FULL EXTENT PERMITTED BY LAW.
