hereof or the date on which such conversion of an existing Interest Rate Option is to be made, the amount thereof and, if applicable, the LIBOR Rate Interest Period therefor. Any oral request for a conversion of an existing Interest Rate Option
shall be followed immediately by the Borrower’s written request therefore. A request from the Borrower pursuant to this Section 2.2b, with respect to the Term Loan or any portion thereof which is to bear interest at the LIBOR Rate Option,
shall irrevocably commit the Borrower to accept such LIBOR Rate Loan on the date specified in such request.

the closing instructions executed by the Borrower and the Bank. Each selection or conversion of an Interest Rate Option applicable to the Term Loan shall be in the minimum principal amount of $1,000,000 or if in excess of $1,000,000 in integral
multiples of $500,000. 
 2.2d Principal Payments on the Term Loan. 
 (i) Scheduled Principal Payments. Principal of the Term Loan shall be repaid in sixteen (16) consecutive quarterly installments beginning

and each of the ninth through the fifteenth quarterly principal installments will be in an amount equal to $900,000. The final quarterly principal installment due on February 28, 2014, shall be in an amount equal to the unpaid principal balance

 (A) Asset Sales. The Borrower shall pay to the Bank, as a
mandatory prepayment of principal on the Term Loan, the Net Cash Proceeds of any disposition of assets permitted by items (ii) and (iii) of Section 6.7; provided, however no such mandatory prepayment of such Net Cash
Proceeds need be made if (I) the Net Cash Proceeds do not exceed in the aggregate $5,000,000 during the term hereof and (II) such Net Cash Proceeds aggregating not more than $10,000,000 are used within one hundred and eighty days of receipt to
acquire other Equipment in which the Bank is granted a first and prior Encumbrance.

Bank, as a mandatory prepayment of principal on the Term Loan, the Net Cash Proceeds of any casualty payment received from an insurance company or eminent domain proceeding; provided, however no such mandatory prepayment of such Net
Cash Proceeds need be made if (I) the Net Cash Proceeds do not exceed in the aggregate $5,000,000 during the term hereof and (II) such Net Cash Proceeds aggregating not more than $5,000,000 are used within one hundred and eighty days of receipt

 2.3 Interest. 
 2.3a Interest Rate. During the
term hereof, the Borrower, in accordance with the provisions of this Section 2.3, but subject to the terms and conditions of the Working Cash Sweep Agreement with respect to outstanding Revolving Credit Loans, shall have the option of electing
from time to time one or more Interest Rate Options set forth below to be applied by the Bank to all or a portion of the Revolving Credit Loans and the Term Loan, as the case may be.

on the day of any such change. 
 (iii) Changes in LIBOR Rate Reserve Percentage. The LIBOR Rate Option shall be adjusted from time to
time, without notice to the Borrower, as necessary to reflect any changes in the LIBOR Rate Reserve Percentage, which adjustments shall be automatically effective on the day of such change.

All interest will be charged to the Parent Account or another account created by the

2.1c hereof to the extent the Borrower has availability under the Revolving Credit Commitment. Such additional interest shall be due and payable within ten (10) days. All accrued and unpaid interest on the Revolving Credit Loan shall be due and

 2.3d Method of Calculation. The interest rate shall be calculated on the basis of
the actual number of days elapsed, using a year of 360 days. Interest for any period shall be calculated from and including the first day thereof to but not including the last day thereof. 
 2.3e Interest Rate Option Elections, Renewals and Conversions. Subject to the remaining provisions of this Agreement, the Borrower shall have the option to
elect to have all or any Borrowing Tranches bear interest at either of the Interest Rate Options and shall have the right to renew elections of Interest Rate Options and convert Borrowing Tranches to the other Interest Rate Option. Notice of the
Borrower’s election shall be made in accordance with Section 2.2b. Elections of, conversions to or renewals of the Base Rate Option shall continue in effect until converted to the LIBOR Rate Option. Elections of, conversions to or renewals
of the LIBOR Rate Option shall expire as to each such LIBOR Rate Option at the expiration of the applicable LIBOR Rate Interest Period. Any Borrowing Tranches outstanding for which no elections have been made shall bear interest under the Base Rate
Option. 
 2.3f Limitation on Election of LIBOR Rate Options. Each election of the LIBOR Rate Option or the prepayment of all or any
LIBOR Rate Loans shall be in the minimum principal amount of $1,000,000 or, if in excess of $1,000,000, in integral multiples of $500,000. At no time during the term hereof may there be more than a total of six (6) separate Borrowing Tranches
in effect, no more than four (4) of which may bear interest at the LIBOR Rate Option. Upon the occurrence and during the continuance of an Event of Default, the Borrower’s right to elect, renew or convert to LIBOR Rate Loans shall be
suspended. 
 2.3g Special Provisions Relating to LIBOR Rate Option. 
 (i) LIBOR Rate Unascertainable. In the event that on any date on which a LIBOR Rate would otherwise be set the Bank shall have determined in
good faith (which determination shall be final and conclusive) that, by reason of circumstances affecting the London interbank market, adequate and reasonable means do not exist for ascertaining the LIBOR Rate, the Bank shall give prompt notice of
such determination to the Borrower, and until the Bank notifies the Borrower that the circumstances giving rise to such determination no longer exist, the right of the Borrower to borrow under, renew or convert to the LIBOR Rate Option shall be
treated as a request to borrow under, renew or convert to the Base Rate Option. 
 (ii) Illegality of Offering LIBOR
Rate. If the Bank shall determine in good faith, which determination shall be final and conclusive, that compliance by the Bank with any applicable Governmental Rule (whether or not having the force of law), or the interpretation or
application thereof by any Governmental Authority has made it unlawful for the Bank to make or maintain LIBOR Rate Loans, the Bank shall give notice of such determination to the Borrower. Notwithstanding any provision of this Agreement to the
contrary, unless and until the Bank shall give notice to the Borrower that the circumstances giving rise to such determination no longer apply: 
 (A) with respect to any LIBOR Rate Interest Periods thereafter commencing, interest on the corresponding LIBOR Rate Loans shall be computed and payable under the Base Rate Option; and 
 
 (B) on such date, if any, as shall be required by law, any LIBOR Rate Loans
then outstanding shall be automatically renewed at the Base Rate Option; and the Borrower shall pay to the Bank the accrued and unpaid interest on such LIBOR Rate Loans to (but not including) such renewal date. The Borrower shall pay the Bank any
additional amounts reasonably necessary to compensate the Bank for any out-of-pocket costs incurred by the Bank as a result of any renewal pursuant to item (B) above on a day other than the last day of the relevant LIBOR Rate Interest Period,
including, but not limited to, any interest or fees payable by the Bank to lenders of funds obtained by it to loan or maintain the Loans so converted. The Bank shall furnish to the Borrower a certificate showing the calculation of the amount
necessary to compensate the Bank for such costs (which certificate, in the absence of manifest error, shall be conclusive), and the Borrower shall pay such amount to the Bank, as additional consideration hereunder, within ten (10) days of the
Borrower’s receipt of such certificate. 
 (iii) Inability to Offer LIBOR Rate. In the event that the Bank shall
determine, in its sole discretion, that it is unable to obtain deposits in the London interbank market in sufficient amounts and with maturities related to the LIBOR Rate Loans which 

  

 14 








 
would enable the Bank to fund such LIBOR Rate Loans, then the Bank shall immediately notify the Borrower that the right of the Borrower to borrow under,
convert to or renew the LIBOR Rate Option shall be suspended. Following notification of the suspension of the LIBOR Rate Option, the Borrower agrees to negotiate with the Bank for a modified LIBOR Rate which will allow the Bank to realize its
anticipated and bargained-for yield. In the event that the Borrower and the Bank cannot agree on a modified LIBOR Rate, any notice of borrowing under, conversion to or renewal of the LIBOR Rate Option which was to become effective during the period
of suspension shall be treated as a request to borrow under, convert to or renew the Base Rate Option with respect to the principal amount specified therein. 
 (iv) Indemnity. In addition to the other provisions of this Section 2.3g, the Borrower hereby agrees to indemnify the Bank against any loss or expense which the Bank may sustain or incur as a
consequence of any default by the Borrower in failing to make any borrowing, conversion or renewal hereunder to bear interest at the LIBOR Rate Option on the scheduled date, in failing to make when due (whether by declaration, acceleration or
otherwise) any payment of any LIBOR Rate Loan or in making any payment or prepayment of any LIBOR Rate Loan or any part thereof on any day other than the last day of the relevant LIBOR Rate Interest Period, including but not limited to any loss of
profit, premium or penalty incurred by the Bank in respect of funds borrowed by it for the purpose of making or maintaining any LIBOR Rate Loan as determined in good faith by the Bank in the exercise of its sole but reasonable discretion. The Bank
shall furnish to the Borrower a certificate showing the calculation of the amount of any such loss or expense (which certificate, absent manifest error, shall be conclusive), and the Borrower shall pay such amount to the affected Bank within ten
days of the Borrower’s receipt of such certificate. 
  

	2.4	Yield Protection; Indemnity. 

 2.4a Yield
Protection. If any Governmental Rule or the interpretation or application thereof by any court or any Governmental Authority charged with the administration thereof, or the compliance with any guideline or request from any central bank or
other Governmental Authority, whether or not having the force of law: 
 (i) subjects the Bank to any tax, levy, impost, charge, fee, duty,
deduction or withholding of any kind hereunder (other than any tax imposed or based upon the income of the Bank and payable to any Governmental Authority or taxing authority of the United States of America or any state thereof) or changes the basis
of taxation of the Bank with respect to payments by the Borrower of principal, interest or other amounts due from the Borrower hereunder (other than any change which affects, and to the extent that it affects, the taxation by the United States of
America or any state thereof of the total net income of the Bank), or 
 (ii) imposes, modifies or deems applicable any reserve, special
deposit, special assessment or similar requirements against assets held by, deposits with or for the account of or credit extended by the Bank, or 
 (iii) imposes upon the Bank any other condition with respect to this Agreement, 
 and the result of any of the foregoing is to increase the cost to
the Bank, reduce the income receivable by the Bank, reduce the rate of return on the Bank’s capital or impose any expense upon the Bank by an amount which the Bank in its sole but reasonable discretion deems to be material, the Bank shall from
time to time notify the Borrower of the amount determined by the Bank (which determination, absent manifest error, shall be conclusive) to be reasonably necessary to compensate the Bank (on an after-tax basis) for such increase in cost, reduction in
income, reduction in rate of return or additional expense, setting forth the calculations therefor, and the Borrower shall pay such amount to the Bank, as additional consideration hereunder, within 10 days of the Borrower’s receipt of such
notice. 
 2.4b Method of Calculation. In determining the amount due the Bank hereunder by reason of the application of this Section 2.4,
the Bank may use any reasonable averaging or attribution method; provided, however, that the Bank must use reasonable efforts to minimize such losses and costs. 
 2.5 Capital Adequacy. If (i) any adoption of, change in or interpretation of any Governmental Rule, or (ii) compliance with any guideline, request or directive of any central bank or other
Governmental Authority or quasi-Governmental Authority exercising control over banks or financial institutions generally, including but not limited to regulations set forth at 12 C.F.R. Part 3 (Appendix A), 12 C.F.R. Part 208 (Appendix A), 12 C.F.R.
Part 225 (Appendix A) and 12 C.F.R. Part 325 (Appendix A) or any court requires that the commitments of the Bank hereunder be treated as an asset or otherwise be included for purposes of calculating the appropriate amount of capital to be maintained
by the Bank or any corporation controlling the Bank (a “Capital Adequacy Event”), the result of which is to reduce the rate of return on the Bank’s capital as a consequence of such commitments to a level below that which the Bank
could have achieved but for such Capital Adequacy Event, taking into consideration the Bank’s policies with respect to capital adequacy, by an amount which the Bank reasonably deems to be material, the Bank shall promptly deliver to the
Borrower a statement of the amount necessary to compensate the Bank for the reduction in the rate of return on its capital attributable to such commitments (the “Capital Compensation Amount”). The Bank shall determine the Capital
Compensation Amount in good faith, using reasonable attribution and averaging methods. The Bank shall from time to time notify the Borrower of the amount so determined setting forth the calculations therefor (which determination, absent manifest
error, shall be conclusive). Such amount shall be due and payable by the Borrower to the Bank 10 Business Days after such notice is given. 
  

 15 








 2.6 Payments. 
 2.6a Place and Manner of Payments. All payments of principal, interest, fees, costs and other amounts due hereunder and under the other Loan Documents not credited to the Bank directly pursuant to the terms hereof or of the
Working Cash Sweep Agreement shall be made by the Borrower to the Bank at the Bank’s principal office at One PNC Plaza, Fifth Avenue and Wood Street, Pittsburgh, Pennsylvania 15222, Attention: Corporate Finance Group, not later than 12:00 noon
(Eastern time) on the due date. All such payments with respect to the Loans shall be immediately good funds when delivered by the Borrower to the Bank. 
 2.6b No Set-Off or Deductions. Subject to the terms of Section 9.5c hereof any and all payments made by the Borrower hereunder shall be made to the Bank in full, without set-off or counterclaim and free and clear of and
without deduction or withholding for, or on account of, any and all present and future Taxes other than Excluded Taxes. If the Borrower is required by law to deduct or withhold any Taxes from or in respect of any sum payable hereunder, (i) the
sum payable shall be increased, as may be necessary, so that after making all required deductions and withholdings (including deductions and withholdings applicable to additional sums payable under this Section) the Bank receives an amount equal to
the sum that it would have received had no deductions or withholdings been made, (ii) the Borrower shall make the required deductions or withholdings, and (iii) the Borrower shall pay the full amount deducted or withheld to the relevant
taxing authority in accordance with any applicable Governmental Rule. The Bank agrees either to repay or credit at Bank’s discretion to the Borrower any refund or tax credit actually received by, or for the benefit of, the Bank for tax amounts
paid by the Borrower pursuant to this Section. 
 2.6c Tax Indemnity. The Borrower shall indemnify the Bank for the full amount of any Taxes
(other than Excluded Taxes) imposed by any jurisdiction on amounts payable by the Borrower under this Section paid or payable by the Bank and for any liability (including penalties, interest and reasonable expenses) arising therefrom or with respect
thereto, whether or not such Taxes were correctly or legally asserted, and for any Taxes (other than Excluded Taxes) levied or imposed with respect to any indemnity payment made under this Section. This indemnification shall be made within 30 days
after the date the Bank makes written demand therefor. If such Taxes are not correctly or legally asserted, the Bank will reasonably cooperate with the Borrower at the Borrower’s expense in contesting such assessment. 
 2.6d Evidence of Payment. Within 30 days after the date of any payment of Taxes withheld by the Borrower in respect of any payment by the Borrower to the
Bank, the Borrower shall furnish to the Bank the original or a certified copy of a receipt issued by the relevant taxing authority evidencing payment by the Borrower to the taxing authority of any Taxes (other than Excluded Taxes) with respect to
any payment payable to the Bank. 
 2.6e Survival. The obligations of the Borrower under this Section shall survive the termination of this
Agreement and the payment of all amounts payable under this Agreement. 
 2.7 Loan Account. The Bank shall open and maintain on its books a
Loan Account in the Borrower’s name with respect to Loans made, repayments, prepayments, the computation and payment of interest and other amounts due and sums paid to the Bank hereunder and under the other Loan Documents. Such Loan Account
shall be conclusive and binding on the Borrower as to the amount at any time due to the Bank from the Borrower except in the case of manifest error in computation. 
 2.8 Payment of Certain Fees. 
 2.8a Commitment Fee. The Borrower shall pay to the Bank, on the last day of each March,
June, September and December during the term of the Revolving Credit Commitment and on the Revolving Credit Termination Date, a Commitment Fee calculated on the basis of the actual number of days elapsed, using a year of 360 days, at a rate per
annum equal to the Applicable Commitment Fee on the average daily (computed at the opening of business) unused amount of the Revolving Credit Commitment (i.e., the Revolving Credit Commitment less the Outstanding Revolving Credit Amount) for the
Fiscal Quarter then ended. The first payment of the Commitment Fee under this Agreement shall be due on March 31, 2009, shall be for the period beginning on the Closing Date. The Commitment Fee shall no longer accrue with respect to portions of
the Revolving Credit Commitment which became permanently unavailable to the Borrower as a result of permanent reductions to the Revolving Credit Commitment made pursuant to Section 2.1b. 
 2.8b Closing Fee. The Borrower shall pay the Closing Fee on the Closing Date. 
 2.9 Payment From Accounts Maintained by Borrower. In the event that any payment of principal, interest, the Commitment Fees, the Letter of Credit Fees, the Closing Fee and any other fee or expense or any
other amount due the Bank under any of the Loan Documents is not paid when due, the Bank is hereby authorized to effect such payment by debiting the Parent Account or any deposit account of the Borrower now or in the future maintained with the Bank
by the Borrower either individually or with another Person. This right of debiting accounts of the Borrower is in addition to any right of setoff accorded the Bank hereunder or by operation of law. 
  

 16 








 2.10 Late Payment. If any payment required to be made by the Borrower hereunder is not made on the due date
thereof, the Borrower shall pay interest on the amount of such required payment at the Default Rate for any Borrowing Tranche bearing interest at the Base Rate Option (whether or not a Borrowing Tranche bearing interest). 
 2.11 Letter of Credit Subfacility. 
 2.11a Letter of
Credit Commitment. At the request of the Borrower, the Bank will issue for the account of the Borrower, on the terms and conditions hereinafter set forth (including without limitation Article 7 hereof), one or more Letters of Credit;
provided, however, no Letter of Credit shall have an expiry date later than fifteen (15) days prior to the Revolving Credit Termination Date; and provided, further, however, that in no event shall (i) the Stated Amount of the Letters of
Credit issued pursuant to this Section 2.11 exceed, at any one time, $2,000,000, or (ii) the sum of aggregate outstanding principal balance of the Revolving Credit Loans, the aggregate unpaid balance of outstanding Revolving Credit Loans,
the aggregate unpaid balance of any Unreimbursed L/C Draws and the aggregate Stated Amount of the Letters of Credit issued by the Bank under this Section 2.11 exceed, at any one time, the aggregate Revolving Credit Commitment. 
 2.11b Letter of Credit Charges. 
 (i) The
Borrower shall pay to the Bank a fee (the “Letter of Credit Fee”) equal to a per annum rate of interest equal to the Applicable Margin for Revolving Credit Loans bearing interest at the LIBOR Rate Option, on the aggregate daily (computed
at the opening of business and on the basis of a year of 360 days and actual days elapsed) Stated Amount of the outstanding Letters of Credit for the period in question. The Letter of Credit Fee shall be payable (A) quarterly in arrears on the
last Business Day of each Fiscal Quarter occurring during the term of this Agreement, (B) on the Revolving Credit Termination Date or (C) upon acceleration of the Revolving Credit Note. Any issuance of an amendment to extend the stated
expiration date of a Letter of Credit or an amendment to increase the Stated Amount of a Letter of Credit shall be treated as an issuance of a new Letter of Credit for purposes of calculation of the Letter of Credit Fee due and payable hereunder.
After the occurrence of an Event of Default and during the continuation thereof, the rate at which the Letter of Credit Fee is calculated shall be increased by two hundred (200) basis points (2%) above the pre-default rate. 
 (ii) The Borrower shall also pay to the Bank for the Bank’s own account the Bank’s customary documentation fees payable with respect to the
Letters of Credit as the Bank may generally charge from time to time. Without limitation, the foregoing shall include all charges and expenses paid or incurred by the Bank in connection with any Letter of Credit, including without limitation:
(A) correspondents’ charges, if any, (B) any and all reasonable out-of-pocket expenses and charges of the Bank in connection with the performance, administration, interpretation, collection and enforcement of this Agreement and any
Letter of Credit, including all reasonable legal fees and expenses, and (C) any and all applicable reserve or similar requirements and any and all premiums, assessments, or levies imposed upon the Bank by any Governmental Authority. 

(iii) If by reason of (A) any change in any Law or any change in the interpretation or application by any judicial or regulatory authority of any
Law or (ii) compliance by the Bank with any direction, request or requirement (whether or not having the force of law) of any Governmental Authority: 
 (A) the Bank shall be subject to any tax, levy, charge or withholding of any nature or to any variation thereof or to any penalty with respect to the maintenance or fulfillment of its obligations under this
Section 2.11, whether directly or by such being imposed on or suffered by the Bank; 
 (B) any reserve, deposit or similar requirement
is or shall be applicable, imposed or modified in respect of the Letters of Credit; or 
 (C) there shall be imposed on the Bank any other
condition regarding this Section 2.11 or the Letters of Credit; 
 and if the result of any of the foregoing is to directly or indirectly increase the
cost to the Bank of issuing or maintaining any Letter of Credit, or to reduce the amount receivable in respect thereof by, the Bank, then and in any such case the Bank may, at any time after the additional cost is incurred or the amount receivable
is reduced, notify the Borrower, and the Borrower shall pay on demand such amounts as the Bank may specify to be necessary to compensate the Bank for such additional cost or reduced receipt, together with interest on such amount from the date of the
notice of such event which results in such increased cost or reduction in amount receivable until payment in full thereof at a rate equal at all times to the Base Rate. The determination by the Bank of any amount due pursuant to this
Section 2.11b as set forth in a certificate setting forth the calculation thereof, shall, in the absence of manifest error, be final and conclusive and binding on all of the parties hereto. 
 2.11c Change in Law. In the event any restrictions are imposed upon the Bank by any Law of any Governmental Authority having jurisdiction over the banking
activities of the Bank which would prevent the Bank from issuing the Letters of Credit or amending the Letters of Credit, the commitment of the Bank to issue the Letters of Credit or enter into any amendment with respect thereto shall be 

  

 17 








 
immediately suspended. The Bank shall promptly notify the Borrower of the existence and nature of any restriction which would cause the suspension of the
commitment of the Bank to issue the Letters of Credit or to enter into amendments with respect thereto. The Borrower will thereupon undertake reasonable efforts to obtain the cancellation of all outstanding Letters of Credit; provided, however, that
the refusal of any beneficiary of a Letter of Credit to surrender such Letter of Credit will not be an Event of Default hereunder, provided that the Borrower shall undertake good faith efforts to obtain substitute letters of credit for the then
existing and outstanding Letters of Credit. Nothing contained in this Section 2.11 shall be deemed a termination of the Revolving Credit Commitment and, in the event of a suspension of the commitment of the Bank to issue Letters of Credit as
set forth above, the Borrower may continue to borrow under the Revolving Credit Commitment provided the requirements of Sections 7.1 and 7.2 are complied with. 
 2.11d Procedures for Issuance of Letters of Credit. When the Borrower desires the issuance of a Letter of Credit, the Borrower shall deliver a duly completed application and agreement for Letter of Credit to the Bank no later
than 10:00 A.M. (Pittsburgh, Pennsylvania time) at least three (3) Business Days, or such shorter period as may be agreed to by the Bank, in advance of the proposed date of issuance. Upon satisfaction of the conditions set forth in
Section 7.1 and, if applicable, Section 7.2, the Bank shall be obligated to issue the Letter of Credit. In determining whether to pay under a Letter of Credit, the Bank shall be responsible only to determine that the documents and
certificates required to be delivered under the Letter of Credit have been delivered and that they comply on their face with the requirements of the Letter of Credit. 
 2.11e Reimbursement of Draws. In the event of any request for drawing under a Letter of Credit by the beneficiary thereof, the Bank shall immediately notify the Borrower, and the Borrower shall
reimburse, or cause the reimbursement of, the Bank on demand as set forth in the applicable application and agreement for Letter of Credit in an amount in same day funds equal to the amount of such drawing; provided, however, that anything contained
in this Agreement to the contrary notwithstanding, unless the Borrower shall have notified the Bank prior to such time that the Borrower intends to reimburse the Bank for all or a portion of the amount of such drawing with funds other than the
proceeds of Revolving Credit Loans, the Borrower shall be deemed to have given a loan request to the Bank requesting the Bank to make Revolving Credit Loans on the first Business Day immediately following the date on which such drawing is honored in
an aggregate amount equal to the excess of the amount of such drawing over the amount received by the Bank from such other funds in reimbursement thereof (the “Unreimbursed L/C Draw”), plus accrued interest on such amount at the rate set
forth in Section 2.3a(i). Any such Revolving Credit Loan shall be deemed advanced to the Borrower. The proceeds of any such Revolving Credit Loans shall be applied directly by the Bank to reimburse the Bank for the Unreimbursed L/C Draw plus
accrued interest on such amount. The foregoing shall not limit or impair the obligation of the Borrower to reimburse the Bank on demand. 
 2.11f

 2.11h Letter of Credit Indemnity. In addition to amounts payable as elsewhere provided in this
Section 2.11, the Borrower hereby agrees to protect, indemnify, pay and save the Bank harmless from and against any and all claims, demands, liabilities, damages, losses, costs, charges and expenses (including reasonable attorneys’ fees)
which the Bank may incur or be subject to as a consequence, direct or indirect, of (i) the issuance of the Letters of Credit or any amendment thereto, other than as a result of the gross negligence or willful misconduct of the Bank as
determined by a court of competent jurisdiction, (ii) the failure of the Bank to honor a draw under any Letter of Credit if the Bank in good faith and upon advice of counsel believes that it is prohibited from making such payment as a result of
any requirement of Law or of any Governmental Authority, or (iii) any material breach by the Borrower of any representation, warranty, covenant, term or condition in, or the occurrence of any default under, any document related to the issuance
or any amendment of the Letters of Credit. If any proceeding shall be brought or threatened against the Bank by reason of or in connection with any event described in clauses (i) through (iii) above, the Bank shall promptly notify the
Borrower in writing, and the Borrower shall assume the defense thereof, including the employment of counsel and payment of all costs of litigation. Notwithstanding the preceding sentence, the Bank shall have the right to employ their own counsel and
to determine its own defense of such action in any such case, but the fees and expenses of such counsel shall be at the expense of the Bank unless (x) the employment of such counsel shall have been authorized in writing by the Borrower,
(y) the Borrower, after the aforementioned notice of the action, shall not have employed counsel to have charge of such defense or (z) if the position of the Borrower is adverse or contrary to the position advocated by the Bank, as the
case may be. In each case described in clauses (x), (y) and (z) immediately above the reasonable fees and expenses of counsel for the Bank, as the case may be shall be borne by the Borrower. The Borrower shall not be liable for any
settlement of any such action affected without its consent. 
 2.11i Payments without Inquiry. The Bank is hereby expressly authorized and
directed to honor any request for payment which is made under and in compliance with the terms of any Letter of Credit without regard to, and without any duty on the Bank’s part to inquire into, the existence of any disputes or controversies
between the Borrower, the beneficiary of any Letter of Credit or any other Person, or the respective rights, duties or liabilities of any of them or whether any facts or occurrences represented in any of the documents presented under any Letter of
Credit are true or correct. Furthermore, the Borrower fully understands and agrees that the Bank’s sole obligation to the Borrower shall be limited to honoring requests for payment made under and in compliance with the terms of any Letter of
Credit, the application and agreement for Letter of Credit therefor and this Agreement and the Bank’s obligation remains so limited even if the Bank may have assisted the Borrower in the preparation of the wording of any Letter of Credit or any
documents required to be presented thereunder or that the Bank may otherwise be aware of the underlying transaction giving rise to any Letter of Credit and this Agreement. 
 2.11j Limitations on Liability of Bank. As between the Borrower and the Bank, the Borrower assumes all risks of the acts and omissions of, or misuse of the Letters of Credit by, the beneficiaries of the
Letters of Credit. In furtherance and not in limitation of the foregoing, the Bank shall not be responsible: (i) for the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party in connection
with the application for or the issuance or amendment of the Letters of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) for the validity or sufficiency of any
instrument transferring or assigning or purporting to transfer or assign the Letters 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) for
failure of a beneficiary of a Letter of Credit to comply fully with conditions required in order to draw upon such Letter of Credit; (iv) for errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail,
cable, telegraph, telecopy, telex or otherwise, whether or not they be in cipher; (v) for errors in interpretation of technical terms; (vi) for any loss or delay in the transmission or otherwise of any document required in order to make a
draw under the Letters of Credit or of the proceeds thereof; (vii) for the misapplication by a beneficiary of any Letter of Credit of the proceeds of any drawing under such Letter of Credit; (viii) for any consequences arising from causes
beyond the control of the Bank, including, without limitation, any Law; and (ix) for any other circumstances whatsoever in making or failing to make payment under a Letter of Credit; except that the Borrower shall have a claim against the Bank,
and the Bank shall be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential, damages suffered by the Borrower by a court of competent jurisdiction to be the result of (i) the Bank’s
willful misconduct or gross negligence in determining whether documents presented under a Letter of Credit comply with the terms of the Letter of Credit, (ii) the Bank’s willful misconduct or gross negligence in paying a draw under a
Letter of Credit to any Person other than the beneficiary of such Letter of Credit or its lawful successor, representative or assign (or as otherwise directed in writing by the beneficiary of such Letter of Credit) or (iii) the Bank’s
willful failure to pay under a Letter of Credit after the presentation to it by the beneficiary of such Letter of Credit or its lawful successor, representative or assign of a sight draft and certificate or other documents strictly complying with
the terms and conditions of such Letter of Credit, unless the Bank in good faith and upon advice of counsel believes that it is prohibited by law or other legal authority from making such payment. None of the above shall affect, impair, or prevent
the vesting of any of the Bank’s rights or powers hereunder. 
 2.11k Reduction in Credit Rating of Bank. Except for the Bank’s
obligations to issue Letters of Credit hereunder and its obligations under such Letters of Credit, the Bank shall have no liability to the Borrower from a reduction of the Bank’s credit rating or any deterioration in its financial condition.

reasonable attorneys’ fees) of the enforcement of any of the Bank’s rights under this Agreement or the Letters of Credit, or of any claim or demand by the Bank against the Borrower, or of any actual or attempted sale, exchange,
enforcement, collection, maintenance, retention, insurance, compromise, settlement, release, delivery on trust receipt, or other security agreement, or delivery of any such security, and of the receipt of proceeds thereof, and will repay to the Bank
any such expenses incurred by the Bank.

resulting liability to the Borrower. 
 2.11n Subrogation Rights of Bank. Whenever appropriate to prevent unjust enrichment and to the end that
the Borrower shall bear substantially all of the risks relative to any Letter of Credit and the underlying transactions, the Bank shall be subrogated (for purposes of defending against the Borrower’s claims and proceeding against others to the
extent of the Bank’s liability to the Borrower) to the Borrower’s rights against any Person who may be liable to the Borrower on any underlying transaction, to the rights of any holder in due course or Person with similar status against
the Borrower, and to the rights of the beneficiary or its assignee or person with similar status against the Borrower.

 4.5 Validity and Binding
Effect. This Agreement has been, and each other Loan Document will be, duly executed and delivered by the Borrower. This Agreement and the other Loan Documents, when delivered by the Borrower pursuant to the provisions hereof, will
constitute legal, valid and binding obligations of the Borrower enforceable against the Borrower in accordance with their respective terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium
or other similar laws affecting the enforcement of creditors’ rights generally and except as such enforceability may be limited by the availability of equitable remedies. 
 4.6 No Conflict. The execution and delivery of this Agreement and the other Loan Documents by the Borrower and the consummation of the transactions herein or therein contemplated or compliance with the

documents, (ii) any Governmental Rule or (iii) any material agreement, instrument, order, writ, judgment, injunction or decree to which the Borrower is a party or by which it is bound or to which it is subject, or will result in the

a reasonable range of possible results in light of the history of the business of the Borrower and its Subsidiaries, present and foreseeable conditions and the intentions of the Borrower’s management. Such projections accurately reflect the
liabilities of the Borrower upon consummation of the transactions contemplated hereby as of the Closing Date. No material events have occurred since the preparation of the projections which would cause the projections taken as a whole, not to be
reasonably attainable. 
 4.8 Material Adverse Change. Since December 31, 2008, no Material Adverse Change has occurred.

threatened against the business, operations, properties, prospects, profits or condition (financial or otherwise) of the Borrower or any Subsidiary of the Borrower at law or in equity, before any Governmental Authority, court or arbitrator which,
individually or in the aggregate, if adversely determined, could reasonably be expected to be material or which purport to affect the rights and remedies of the Bank pursuant to this Agreement and the other Loan Documents or which purport to
restrain or enjoin (either temporarily, preliminarily or permanently) the performance by either the Borrower or any Subsidiary of the Borrower of any action contemplated by any of the Loan Documents. All pending and, to the Borrower’s
knowledge, threatened actions, suits, proceedings and investigations affecting the Borrower and any Subsidiary of the Borrower are set forth on Schedule 4.10.

a “disqualified person” (as that term is defined in Section 4975 of the Internal Revenue Code) with respect to any “employee benefit plan” (as defined in Section 3(3) of ERISA), has engaged in a “prohibited
transaction” (as defined in Section 406 of ERISA or Section 4975 of the Internal Revenue Code) involving any such employee benefit plan which will subject the Borrower or such ERISA Affiliate to the tax or penalty imposed under

respect to, or resulting from, any delay in paying or failure to pay any such taxes or similar impositions. The obligations of the Borrower pursuant to this Section 9.2 shall survive the termination of this Agreement and the repayment of the

 9.5b Right of Setoff. The Borrower agrees that if amounts outstanding under this Agreement and the Notes
are due and unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall be deemed to have, to the extent permitted by applicable law, the right of setoff in respect of
its Participation in amounts owing under this Agreement and the Notes to the same extent as if the amount of its Participation were owing directly to it as a lender under this Agreement or the Notes. 
 9.5c Withholding of Income Taxes. If any Participant or purchasing lender is not a United States person within the meaning of Section 7701(a)(30) of
the Internal Revenue Code such Participant of purchasing lender shall promptly (but in any event prior to the initial payment of interest hereunder) deliver to the Borrower and the Bank two executed copies of (i) Internal Revenue Service Form
W-8BEN or any successor form specifying the applicable tax treaty between the United States and the jurisdiction of such Participant’s or purchasing lender’s domicile that provides for the exemption from withholding on interest payments to
such Participant or purchasing lender, (ii) Internal Revenue Service Form W-8ECI or any successor form evidencing that the income to be received by such Participant or purchasing lender hereunder is effectively connected with the conduct of a
trade or business in the United States or (iii) other evidence satisfactory to the Borrower and the Bank that such Participant or purchasing lender is exempt from United States income tax withholding with respect to such income. Such
Participant or purchasing lender shall amend or supplement any such form or evidence as required to insure that it is accurate, complete and non-misleading at all times. In addition, from time to time upon the reasonable request of Borrower and the
Bank, each Participant or purchasing lender shall complete and provide Borrower and the Bank with such forms, certificates or other documents as may be reasonably necessary to allow Borrower or the Bank, as applicable, to make any payment under this
Agreement or the other Loan Documents without any withholding for or on the account of any Tax pursuant to Section 2.5b hereof. 
 9.6 Successors
and Assigns. This Agreement shall be binding upon the Borrower and the Bank and their respective successors and assigns, and shall inure to the benefit of the Borrower, the Bank and their respective successors and assigns; provided,
however, that the Borrower shall not assign its rights or duties hereunder or under any of the other Loan Documents without the prior written consent of the Bank. 
 9.7 Confidentiality. The Bank shall keep confidential and not disclose to any Person, other than its directors, officers, employees, Affiliates and agents, and to actual or potential Participants, all
non-public information concerning the Borrower and the Borrower’s Affiliates which comes into the Bank’s possession during the term hereof. Notwithstanding the foregoing, the Bank may disclose information concerning the Loan Parties
(i) in accordance with normal banking practices and the Bank’s policies concerning disclosure of such information, (ii) to any Participant or potential Participant, (iii) pursuant to what the Bank believes to be the lawful
requirements or request of any Governmental Authority regulating banks or banking, (iv) as required by any Governmental Rule, judicial process or subpoena, and (v) to its attorneys, accountants and auditors. 
 9.8 Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or enforceability without invalidating the remaining portions hereof in such jurisdiction or affecting the validity or enforceability of such or any other provision hereof in any other jurisdiction. 
 9.9 Interest Limitation. Notwithstanding anything to the contrary herein contained, the total liability of the Borrower for payment of interest pursuant
hereto shall not exceed the maximum amount, if any, of such interest permitted by any applicable Governmental Rule to be contracted for, charged or received, and if any payment by the Borrower to the Bank includes interest in excess of such a
maximum amount, the Bank shall apply such excess to the reduction of the unpaid principal amount due pursuant hereto, or if none is due, such excess shall be refunded to the Borrower; provided that, to the extent permitted by applicable
Governmental Rules, in the event the interest is not collected, is applied to principal or is refunded pursuant to this sentence and interest thereafter payable pursuant hereto shall be less than such maximum amount, then such interest thereafter so
payable shall be increased up to such maximum amount to the extent necessary to recover the amount of interest, if any, theretofore uncollected, applied top principal or refunded pursuant to this sentence. Any such application or refund shall not
cure or waive any Default or Event of Default. In determining whether or not any interest payable under this Agreement exceeds the highest rate permitted by law, any non-principal payment (except payments specifically stated in this Agreement to be
“interest”) shall be deemed, to the extent permitted by applicable law, to be an expense, fee, premium or penalty rather than interest. To the extent permitted by applicable law, the Borrower hereby waives any provision of law which
renders any provision hereof prohibited, unenforceable or not authorized in any respect. 
 9.10 Survival. Except as otherwise provided in
Sections 4.20, 5.13, 9.2 and 9.3, all representations, warranties, covenants and agreements of the Borrower contained herein or in the other Loan Documents or made in writing in connection herewith shall survive the issuance of the Notes and shall
continue in full force and effect so long as the Borrower may borrow hereunder and so long thereafter until all of the Obligations are paid in full. 
 9.11 GOVERNING LAW. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF PENNSYLVANIA, WITHOUT REGARD TO THE PRINCIPLES THEREOF REGARDING CONFLICT OF
LAWS, EXCEPTING APPLICABLE FEDERAL LAW AND EXCEPT ONLY TO THE EXTENT PRECLUDED BY THE MANDATORY APPLICATION OF THE LAW OF ANOTHER JURISDICTION.

are intended for convenience only and shall not affect the meaning or construction of this Agreement. 
 9.16 Counterparts; Effectiveness. This
Agreement and any amendment hereto may be executed in several counterparts and by each party on a separate counterpart, each of which, when so executed and delivered, shall be an original, but all of which together shall constitute but one and the

delivered (which delivery may be by telecopier) at least one executed counterpart hereof or of the signature page hereto. 
 9.17 WAIVER OF JURY
