(e) It does not arise from a sale of goods that are delivered or to be delivered outside the United States of America or from a sale of goods to an account debtor domiciled outside of the United States of America, unless the sale is (i) on a letter of credit, which is in form and substance and issued by a financial institution satisfactory to the Bank and which has been issued or confirmed by a bank that is organized under the Laws of the United States of America or a state thereof and which has been transferred or assigned to the Bank as additional security or (ii) insured by credit insurance, with an insurance company acceptable to the Bank that names the Bank as an additional insured and lender/loss payee with respect thereto;

(j) It does not constitute a finance charge;

- 7 -

(k) No notice of bankruptcy, insolvency or material adverse change of the account debtor has been received by or is known to the Borrowers;

(l) It is not a Receivable with respect to which there is an unresolved dispute with respect to the account debtor’s obligation thereunder; provided, however, that to the extent that there is an unresolved dispute with respect to the account debtor’s obligations under such Receivable, such Receivable shall be ineligible solely to the extent of the disputed amount thereof, unless otherwise ineligible under this definition;

(m) It is not a Receivable evidenced by an “instrument” or “chattel paper” (each as defined in the UCC) not in the possession of the Bank;

- 27 -

If any financial statement or certificate delivered pursuant to Article V is shown to be inaccurate (regardless of whether this Agreement is in effect when such inaccuracy is discovered), and such inaccuracy, if corrected, would have led to the application of a higher Applicable Base Rate Margin, Applicable Libor Rate Margin or Applicable L/C Fee Percentage for any period (such period, the “Applicable Period”), than the Applicable Base Rate Margin, Applicable Libor Rate Margin or Applicable L/C Fee Percentage, as applicable, actually applied to such Applicable Period, then, upon the written request of the Bank, such margin or percentage shall be determined in accordance with the correct financial information for such Applicable Period and the Borrowers shall immediately pay to the Bank any accrued additional interest and fees owing as a result of such increased margin or percentage for such Applicable Period, which payment shall be applied promptly by the Bank to the Lenders in accordance with the terms of this Agreement.

(d) Interest After Maturity or Default; Interest Laws. Upon the occurrence and during the continuance of an Event of Default, (i) the unpaid principal amount of the Loans or any portion thereof, accrued interest thereon, any fees or any other sums payable hereunder shall thereafter until paid in full bear interest at a rate per annum equal to the Applicable Rate plus three percent (3.00%); (ii) each Libor Rate Loan shall automatically convert into a Base Rate Loan at the end of the applicable Interest Period; and (iii) no Loans may be made as, renewed as or converted into a Libor Rate Loan.

- 28 -

of interest permitted by applicable Law (“Excess Interest”). If any Excess Interest is provided for or determined by a court of competent jurisdiction to have been provided for in this Agreement or in any other Loan Document, then, in such event: (1) the provisions of this subsection shall govern and control; (2) the Borrowers shall not be obligated to pay any Excess Interest; (3) any Excess Interest that the Bank may have received hereunder shall be, at the Bank’s option, (a) applied as a credit against the outstanding principal balance of the Debt or accrued and unpaid interest (not to exceed the maximum amount permitted by Law), (b) refunded to the payor thereof, or (c) any combination of the foregoing; (4) the interest rate(s) provided for herein shall be automatically reduced to the maximum lawful rate allowed from time to time under applicable Law (the “Maximum Rate”), and this Agreement and the other Loan Documents shall be deemed to have been and shall be, reformed and modified to reflect such reduction; and (5) the Borrowers shall have no action against the Bank for any damages arising out of the payment or collection of any Excess Interest. Notwithstanding the foregoing, if for any period of time interest on any Debt is calculated at the Maximum Rate rather than the Applicable Rate, and thereafter such Applicable Rate becomes less than the Maximum Rate, the rate of interest payable on such Debt shall remain at the Maximum Rate until the Bank shall have received the amount of interest which the Bank would have received during such period on such Debt had the rate of interest not been limited to the Maximum Rate during such period.

2.04 Fees.

The Borrowers shall pay to the Bank:

Each request for a Letter of Credit shall be delivered to the Bank no later than 10:00 a.m. (Pittsburgh, Pennsylvania time) on the third (3^rd) Business Day, or such shorter period as may be agreed to by the Bank, prior to the proposed date of issuance. Each such request shall be in a form acceptable to the Bank and shall specify the Letter of Credit Face Amount thereof, the account party, the beneficiary, the intended date of issuance, the expiry date thereof, and the nature of the transaction to be supported thereby. All such Letters of Credit shall be issued by the Bank in accordance with its then current practice relating to the issuance of Letters of Credit including, but not limited to, the execution and delivery to the Bank of applications and agreements required by the Bank and the payment by the Borrowers of all applicable fees required by Section 2.07 hereof.

2.07 Letter of Credit Fees.

The Borrowers shall pay to the Bank (i) the Bank’s customary issuance fee with respect to each Letter of Credit issued hereunder, such fee to be paid on the date of issuance of each Letter of Credit, (ii) the Bank’s standard amendment fees for each amendment of any Letter of Credit issued hereunder, such fee to be paid on the date of the amendment of such Letter of Credit, and (iii) any out-of-pocket expenses and costs incurred by the Bank for the issuance of any Letter of Credit issued hereunder, such costs and expenses to be paid on demand. The Borrowers shall also pay to

- 30 -

the Bank a fee (the “Letter of Credit Commission”), based on a daily calculation equal to the amount of the Letters of Credit Outstanding on each day multiplied by the applicable percentage determined by reference to the Senior Leverage Ratio as set forth in Section 2.03(a) hereof (the “Applicable LC Fee Percentage”). Such Letter of Credit Commission shall be payable quarterly in arrears beginning on October 1, 2011 and continuing on the first (1^st) day of each January, April, July and October thereafter and on the Expiration Date. Notwithstanding the foregoing, after the occurrence and during the continuance of an Event of Default, the Letter of Credit Commission, as calculated above, shall be increased by three percent (3.0%) per annum.

2.08 Payments and Nature of Borrowers’ Obligations Under Letters of Credit.

(a) Upon a draw under any Letter of Credit, the Borrowers shall immediately reimburse the Bank for such drawing under a Letter of Credit. If (i) the Borrowers shall not have immediately reimbursed the Bank for such drawing under such Letter of Credit, (ii) the Bank must for any reason return or disgorge such reimbursement or (iii) the Borrowers are required to make a payment under Section 7.02(a) hereof and fail to make such payment, then the amount of each unreimbursed drawing under such Letter of Credit and payment required to be made under Section 7.02(a) hereof shall automatically be converted into a Revolving Credit Loan which shall be a Base Rate Loan made on the date of such drawing for all purposes of this Agreement.

(b) The Borrowers’ obligations to the Bank under any Letter of Credit or Letter of Credit Related Documents are absolute, unconditional and irrevocable, and shall be paid and performed in accordance with the terms hereof and thereof irrespective of any act, omission, event or condition, including, without limitation (i) the form of, any lack of power or authority of any signer of, or the lack of validity, sufficiency, accuracy, enforceability or genuineness of (or any defect in or forgery of any signature or endorsement on) any draft, demand, document, certificate or instrument presented in connection with any Letter of Credit, or any fraud or alleged fraud in connection with any Letter of Credit or any obligation underlying any Letter of Credit, in each case, even if the Bank or any of its correspondents have been notified thereof; (ii) any claim of breach of warranty that might be made by a Borrower or the Bank against any beneficiary of a Letter of Credit, or the existence of any claim, set off, recoupment, counterclaim, cross-claim, defense, or other right that a Borrower may at any time have against any beneficiary, any successor beneficiary, any transferee or assignee of the proceeds of a Letter of Credit, the Bank or any correspondent or agent of the Bank, or any other person, however arising; (iii) any acts or omissions by, or the solvency of, 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; (iv) any failure by the Bank to issue any Letter of Credit in the form requested by a Borrower, unless the Bank receives written notice from the Borrower of such failure within three (3) Business Days after the Bank shall have furnished a Borrower (by facsimile transmission or otherwise) a copy of such Letter of Credit and such error is material; and (v) any action or omission (including failure or compulsion to honor a presentation under any Letter of Credit) by the Bank or any of its correspondents in connection with a Letter of Credit, draft or other demand for payment, document, or any property relating to a Letter of Credit, and resulting from any censorship, Law, regulation, order, control, restriction, or the like, rightfully or wrongly exercised by any Official Body, or from any other cause beyond the reasonable control of the Bank or any of its correspondents, or for any loss or damage to a Borrower or to anyone else, or to any property of a Borrower or anyone else, resulting from any such action or omission.

- 31 -

(c) The Bank is authorized to honor any presentation under a Letter of Credit without regard to, and without any duty on the Bank’s part to inquire into, any transaction or obligation underlying such Letter of Credit, or any disputes or controversies between a Borrower and any beneficiary of a Letter of Credit, or any other person, notwithstanding that the Bank may have assisted a Borrower in the preparation of the wording of any Letter of Credit or any Letter of Credit Documents related thereto required to be presented thereunder or that the Bank may be aware of any underlying transaction or obligation or be familiar with any of the parties thereto.

(d) Each Borrower agrees that any action or omission by the Bank or any of its correspondents in connection with any Letter of Credit or presentation thereunder shall be binding on such Borrower and shall not result in any liability of the Bank or any of its correspondents to such Borrower in the absence of the gross negligence or willful misconduct of the Bank. Without limiting the generality of the foregoing, the Bank and each of its correspondents (i) may rely on any oral or other communication believed in good faith by the Bank or such correspondent to have been authorized or given by or on behalf of a Borrower; (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 Bank; (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 separately delivered), 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; and (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. In no event shall the Bank be liable to any Borrower 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.

(e) If a Borrower or any other person seeks to delay or enjoin the honor by the Bank of a presentation under a Letter of Credit, the Bank shall have no obligation to delay or refuse to honor the presentation until validly so ordered by a court of competent jurisdiction.

2.09 Period of Issuance and Term of Letters of Credit.

The term of any Letter of Credit issued, renewed or extended by the Bank for the account of the Borrowers hereunder shall expire not less than thirty (30) days prior to the Expiration Date.

2.10 Booking of Libor Rate Loans.

The Bank may make, carry or transfer Libor Rate Loans at, to or for the account of, any of its branch offices or the office of an affiliate of the Bank; provided, however, that no such action shall result in increased liability or cost to the Borrowers, including any liability or cost pursuant to Section 2.12 or Section 2.13 hereof.

- 32 -

2.11 Assumptions Concerning Funding of Libor Rate Loans.

Calculation of all amounts payable to the Bank under Section 2.12(c) shall be made as though the Bank had actually funded its relevant Libor Rate Loan through the purchase of a Libor deposit bearing interest at the Libor Rate in an amount equal to the amount of that Libor Rate Loan and having maturity comparable to the relevant Interest Period and through the transfer of such Libor deposit from an offshore office to a domestic office in the United States of America; provided, however, that the Bank may fund each of its Libor Rate Loans in any manner it sees fit and the foregoing assumption shall be utilized only for the calculation of amounts payable under Section 2.12(c).

2.12 Additional Costs.

(a) If, due to either (i) the introduction of, or any change in, or in the interpretation of, any Law or (ii) the compliance with any guideline or request from any central bank or other Official Body (whether or not having the force of Law), there shall be any increase in the cost to, or reduction in income receivable by, the Bank of making, funding or maintaining Loans (or commitments to make the Loans), then the Borrowers shall from time to time, upon demand by the Bank, pay to the Bank additional amounts sufficient to reimburse the Bank for any such additional costs or reduction in income. A certificate of the Bank submitted to the Borrowers in good faith as to the amount of such additional costs shall be conclusive and binding for all purposes, absent manifest error. Within five (5) Business Days after the Bank notifies the Borrowers of any such additional costs pursuant to this Section 2.12(a), the Borrowers may either (A) prepay in full all Loans of any types so affected then outstanding, together with interest accrued thereon to the date of such prepayment or (B) convert all Loans of any type so affected then outstanding into Loans of any other type not so affected upon not less than four (4) Business Days’ notice to the Bank. If any such prepayment or conversion of any Libor Rate Loan occurs on any day other than the last day of the applicable Interest Period for such Loan, the Borrowers also shall pay to the Bank such additional amounts as set forth in Section 2.12(c).

(b) If either (i) the introduction of, or any change in, or in the interpretation of, any Law or (ii) the compliance with any guideline or request from any central bank or other Official Body (whether or not having the force of Law), affects or would affect the amount of capital required or expected to be maintained by the Bank or any corporation controlling the Bank and the Bank determines that the amount of such capital is increased by or based upon the existence of the Loans (or commitment to make the Loans) and other extensions of credit (or commitments to extend credit) of similar type, then, upon demand by the Bank, the Borrowers shall pay to the Bank from time to time as specified by the Bank, additional amounts sufficient to compensate the Bank in the light of such circumstances, to the extent that the Bank reasonably determines such increase in capital to be allocable to the existence of the Bank’s Loans (or commitment to make the Loans). A certificate of the Bank in good faith submitted to the Borrowers as to such amounts shall be conclusive and binding for all purposes, absent manifest error. Within five (5) Business Days after the Bank provides such certificate to the Borrowers of any such additional costs pursuant to this Section 2.12(b), the Borrowers may either (A) prepay in full all Loans of any types so affected then outstanding, together with interest accrued thereon to the date of such prepayment or (B) convert all Loans of any type so affected then outstanding into Loans of any other type not so affected upon not less than four (4) Business Days’ notice to

- 33 -

the Bank. If any such prepayment or conversion of any Libor Rate Loan occurs on any day other than the last day of the applicable Interest Period for such Loan, the Borrowers also shall pay to the Bank such additional amounts as set forth in Section 2.12(c).

(c) If the Borrowers shall prepay any Libor Rate Loan on a day other than the last day of the applicable Interest Period for such Loan (whether such prepayment is permitted by (i) this Section 2.12 or Section 2.13, (ii) as a result of the failure by the Borrowers to consummate a transaction after providing notice as set forth in Section 2.01(d), (iii) otherwise permitted by the Bank or (iv) otherwise permitted or required under the terms of this Agreement), the Borrowers shall pay to the Bank on demand such additional amounts as are sufficient to indemnify the Bank against any reasonable loss, cost or expense incurred by the Bank as a result of such prepayment including, without limitation, any loss (including loss of anticipated profits), costs or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by the Bank to fund such Loan, and a certificate as to the amount of any such loss, cost or expense submitted by the Bank to the Borrowers in good faith shall be conclusive and binding for all purposes, absent manifest error.

2.13 Illegality; Impracticability.

Notwithstanding any other provision contained in this Agreement, if: (a) it is unlawful, or any central bank or other Official Body shall determine that it is unlawful, for the Bank to perform its obligations hereunder to make or continue Loans hereunder; or (b) on any date on which a Libor Rate would otherwise be set, the Bank shall have in good faith determined (which determination shall be conclusive absent manifest error) that (i) adequate and reasonable means do not exist for ascertaining a Libor Rate, (ii) a contingency has occurred which materially and adversely affects the interbank markets, or (iii) the effective cost to the Bank of funding a proposed Libor Rate Loan exceeds the Libor Rate then (y) upon notice thereof by the Bank to the Borrowers, the obligation of the Bank to make or continue a Loan of a type so affected shall thereafter be an obligation to make Base Rate Loans whenever any written notice requests any type of Loans so affected and (z) within five (5) Business Days after demand therefor by the Bank to the Borrowers, the Borrowers shall (i) forthwith prepay in full all Loans of the type so affected then outstanding, together with interest accrued thereon or (ii) request that the Bank, upon five (5) Business Days’ notice, convert all Loans of the type so affected then outstanding into Loans of a type not so affected. If any such prepayment or conversion of any Libor Rate Loan occurs on any day other than the last day of the applicable Interest Period for such Libor Rate Loan, the Borrowers also shall pay to the Bank such additional amounts as set forth in Section 2.12(c).

2.14 Loan Account.

The Bank shall open and maintain in its books and records, including computer records, in accordance with its customary procedures, a loan account (the “Loan Account”) in the Borrowers’ names in which shall be recorded the date and amount of each Loan made by the Bank and the date and amount of each payment and prepayment in respect thereof. The Bank shall record in the Loan Account the principal amount of the Loans owing to the Bank from time to time. Except in the case of manifest error in computation, the Loan Account will be conclusive and binding on the Borrowers as to the accuracy of the information contained therein. Failure by the Bank to make any such notation or record shall not affect the obligations of the Borrowers to the Bank with respect to the Loans.

- 34 -

2.15 Security.

The Loans shall be secured by the Security Agreement, the Patent and Trademark Security Agreement, the Stock Pledge Agreements, and all UCC-1 financing statements and other similar instruments executed and recorded with respect to each of the foregoing.

2.16 Financing Statements.

Promptly upon request by the Bank, the Borrowers agree to execute, if applicable, and deliver and file and record and refile and rerecord all financing statements, assignments, notices of security interest, certificates of title, certificates of documentation and such other documents, in such manner, at such time or times and in such place or places as may be required by Law or as may be requested by the Bank in order to cause the Liens granted under the Security Agreement or any other Loan Document to be, at all times valid, perfected and enforceable against such Borrower and all third parties. Each Borrower irrevocably appoints the Bank as its agent and attorney to execute any such financing statements or other instruments described above in its name or, if applicable, to file any such financing statements or other instruments described above without such Borrower’s signature. Each Borrower further agrees that a carbon, photographic or other reproduction of a financing statement or the Security Agreement are sufficient as a financing statement and may be filed as such.

2.17 Working Cash® Subfacility.

Notwithstanding anything contained in Section 2.01 to the contrary, the Revolving Credit Facility Commitment shall include a subfacility (the “Working Cash® Subfacility”) in an aggregate amount not to exceed the Revolving Credit Facility Commitment Amount (the “Working Cash® Subfacility Commitment”), which shall contain an investment and borrowing sweep feature pursuant to the terms and conditions of the Working Cash® Sweep Rider, the terms of which are hereby incorporated in this Agreement, until such Working Cash® Sweep Rider is terminated in accordance with its terms. Therefore, so long as the Working Cash® Sweep Rider is in effect, the Borrowers may request that the Bank make Revolving Credit Loans subject to the Working Cash® Sweep Rider in an aggregate amount not to exceed the Working Cash® Subfacility Commitment. The terms and conditions of the Working Cash® Sweep Rider shall supersede the terms and conditions of this Agreement for all Revolving Credit Loans requested under the Working Cash® Subfacility, as such terms and conditions relate to, among other things, making Revolving Credit Loans, the interest rate (but not the interest rate margin) applicable to such Revolving Credit Loans and the repayment of principal and interest on such Revolving Credit Loans.

8.05 Expenses; Taxes; Attorneys Fees.

The Borrowers agree to pay or cause to be paid and to save the Bank harmless against liability for the payment of all reasonable out-of-pocket expenses including, but not limited to, reasonable fees and expenses of both internal and external counsel and paralegals for the Bank, incurred by the Bank from time to time (i) arising in connection with the preparation, execution, delivery and performance of this Agreement, the Notes and the other Loan Documents, (ii) relating to any requested amendments, waivers or consents to this Agreement, the Notes or any of the other Loan Documents and (iii) arising in connection with the Bank’s enforcement or preservation of rights under this Agreement, the Notes or any of the other Loan Documents including, but not limited to, such expenses as may be incurred by the Bank in the collection of the outstanding principal amount of the Loans. The Borrowers agree to pay all stamp, document, transfer, recording or filing taxes or fees and similar impositions now or in the future determined in good faith by the Bank to be payable in connection with this Agreement, the Notes or any other Loan Document. The Borrowers agree to save the Bank 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. In the event of a determination adverse to the Borrowers of any action at Law or suit in equity in relation to this Agreement, the Notes or the other Loan Documents, the Borrowers will pay, in addition to all other sums which the Borrowers may be required to pay, a reasonable sum for attorneys’ and paralegals’ fees incurred by the Bank or the holder of any Note in connection with such action or suit. All payments due from the Borrowers under this Section 8.05 will be added to and become part of the Debt until paid in full.

- 66 -

8.06 Severability.

The provisions of this Agreement are intended to be severable. If any provision of this Agreement is 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 of the provision in any other jurisdiction or the remaining provisions of this Agreement in any jurisdiction.

8.07 Governing Law; Consent to Jurisdiction.

This Agreement will 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 substantive Laws, and not the Laws of conflicts, of said Commonwealth. The Borrowers consent to the exclusive jurisdiction and venue of the federal and state courts located in Allegheny County, Pennsylvania, in any action on, relating to or mentioning this Agreement, the Notes, the other Loan Documents or any one or more of them.

8.08 Prior Understandings.

This Agreement, the Notes and the other Loan Documents supersede all prior understandings and agreements, whether written or oral, among the parties relating to the transactions provided for in this Agreement, the Notes and the other Loan Documents.

8.09 Duration; Survival.

All representations and warranties of the Borrowers contained in this Agreement or made in connection with this Agreement or any of the other Loan Documents shall survive the making of and will not be waived by the execution and delivery of this Agreement, the Notes or the other Loan Documents, by any investigation by the Bank, or the making of any Loan or issuance of any Letter of Credit. Notwithstanding termination of this Agreement or the occurrence of an Event of Default, all covenants and agreements of the Borrowers will continue in full force and effect from and after the date of this Agreement so long as the Borrowers may borrow under this Agreement and until payment in full of the Notes, interest thereon, and all fees and other obligations of the Borrowers under this Agreement or the Notes. Without limitation, it is understood that all obligations of the Borrowers to make payments to or indemnify the Bank will survive the payment in full of the Notes and of all other obligations of the Borrowers under this Agreement, the Notes and the other Loan Documents.

8.10 Counterparts.

This Agreement may be executed in any number of counterparts and by the different parties to this Agreement on separate counterparts each of which, when so executed, will be deemed an original, but all such counterparts will constitute but one and the same instrument.

8.11 Successors and Assigns; Termination.

(a) This Agreement will be binding upon and inure to the benefit of the Bank, the Borrowers and their respective successors and assigns, except that no Borrower may assign

- 67 -

or transfer any of its rights under this Agreement without the prior written consent of the Bank. The Borrowers may terminate this Agreement at any time upon ten (10) Business Days’ prior written notice and the final, unconditional payment in full in cash or other immediately available funds of the Debt (other than inchoate indemnification obligations).

(b) The termination of this Agreement shall not affect any Borrower’s or the Bank’s rights, or any of the Debt having its inception prior to the effective date of such termination, and the provisions hereof shall continue to be fully operative until all transactions entered into, rights or interests created or Debt have/has been fully and indefeasibly paid, disposed of, concluded or liquidated. The security interests, Liens and rights granted to the Bank hereunder and under the other Loan Documents and the financing statements filed in connection with this Agreement and the other Loan Documents shall continue in full force and effect, notwithstanding the termination of this Agreement or the fact that Borrowers’ Loan Account may from time to time be temporarily in a zero (0) or credit position, until all of the Debt (other than inchoate indemnification obligations) of each Loan Party shall have been indefeasibly paid and performed in full after the termination of this Agreement or each Loan Party has furnished the Bank with an indemnification satisfactory to the Bank with respect thereto. Accordingly, each Loan Party waives any rights which it may have under the Uniform Commercial Code to demand the filing of termination statements with respect to the Collateral, and the Bank shall not be required to send such termination statements to each Loan Party, or to file them with any filing office, unless and until this Agreement shall have been terminated in accordance with its terms and all Debt shall have been indefeasibly paid in full in immediately available funds. All representations, warranties, covenants, waivers and agreements contained herein shall survive termination hereof until all Debt is indefeasibly paid and performed in full (other than inchoate indemnification obligations).

8.12 No Third Party Beneficiaries.

The rights and benefits of this Agreement and the other Loan Documents are not intended to, and shall not, inure to the benefit of any third party.

8.13 Participation and Assignment.

The Bank may from time to time participate, sell or assign all or any part of the Loans made by the Bank or which may be made by the Bank, or its right, title and interest in the Loans or in or to this Agreement, to another lending office, lender or financial institution. Except to the extent otherwise required by the context of this Agreement, the word “Bank” where used in this Agreement means and includes any holder of a Note originally issued to the Bank and each such holder of a Note will be bound by and have the benefits of this Agreement, the same as if such holder had been a signatory to this Agreement. In connection with any such sale, assignment or grant of participation, the Bank may make available to any prospective purchaser, assignee or participant any information relative to the Borrowers in the Bank’s possession; provided such prospective purchaser, assignee, or participant agrees to hold such information in confidence.

8.16 Indemnity.

In addition to the payment of expenses pursuant to Section 8.05 hereof, whether or not the transactions contemplated hereby shall be consummated, the Borrowers agree to indemnify, pay and hold the Bank and the officers, directors, employees, agents, consultants, auditors, affiliates and attorneys of the Bank (collectively, the “Indemnitees”), harmless from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs, expenses and disbursements of any kind or nature whatsoever (including the reasonable fees and disbursements of counsel for such Indemnitees in connection with any investigative, administrative or judicial proceeding commenced or threatened, whether or not such Indemnitee shall be designated a party thereto) that is imposed on, incurred by, or asserted against that Indemnitee, in any manner relating to or arising out of this Agreement or the other Loan Documents, the consummation of the transactions contemplated by this Agreement, the statements contained in the commitment letters, if any, delivered by the Bank, the Bank’s agreement to make the Loans or issue Letters of Credit hereunder, the use or intended use of the proceeds of any of the Loans or the exercise of any right or remedy hereunder or under any of the other Loan Documents, any error, failure or delay in the performance of any of the Bank’s obligations under this Agreement caused by natural disaster, fire, war, strike, civil unrest, error or inoperability of communication equipment or lines or any other circumstances beyond the control of the Bank or actions taken by the Bank which were reasonably believed by the Bank to be taken pursuant to this Agreement including, but not limited to, actions taken by the Bank to amend or cancel any funds transfer instructions or any decision by the Bank to effect or not to effect the transfer as provided in this Agreement, or any other such action taken by the Bank in good faith pursuant to its responsibilities under this Agreement (the “Indemnified Liabilities”); provided, however, that the Borrowers shall have no obligation to an Indemnitee hereunder with respect to Indemnified Liabilities arising from the gross negligence, bad faith or willful misconduct of that or another Indemnitee as finally determined by a court of competent jurisdiction.

8.17 Limitation of Liability.

To the fullest extent permitted by Law, no claim may be made by any Loan Party against the Bank or any affiliate, director, officer, employee, attorney or agent of the Bank for any special, incidental, consequential or punitive damages in respect of any claim arising from or relating to this Agreement or any other Loan Document or any statement, course of conduct, act, omission or event occurring in connection herewith or therewith (whether for breach of contract, tort or any other theory of liability). Each Loan Party hereby waives, releases and agrees not to xxx upon any claim for any such damages, whether such claim presently exists or arises hereafter and whether or not

- 69 -

such claim is known or is suspected to exist in its favor. This Section 8.17 shall not limit any rights of the Loan Parties arising solely out of gross negligence, bad faith or willful misconduct of the Bank Indemnities as finally determined by a court of competent jurisdiction.

8.18 Confidentiality.

(a) General. The Bank agrees to keep confidential all information obtained from a Loan Party which is nonpublic and confidential or proprietary in nature (including any information such Loan Party specifically designates as confidential), except as provided below, and to use such information only in connection with this Agreement and for the purposes contemplated hereby. The Bank 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 8.13, and prospective assignees and participants, (iii) to the extent requested by any bank regulatory authority or, with notice to the Loan Parties, 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 or the other Loan Documents, (iv) if it becomes publicly available other than as a result of a breach of this Agreement or becomes available from a source not known to be subject to confidentiality restrictions, or (v) if the Loan Parties shall have consented to such disclosure.

(b) Sharing Information With Affiliates of the Bank. The Borrowers acknowledge that from time to time financial advisory, investment banking and other services may be offered or provided to the Borrowers or one or more of their Affiliates (in connection with this Agreement or otherwise) by the Bank or by one or more Subsidiaries or Affiliates of the Bank and the Borrowers hereby authorize the Bank to share any information delivered to the Bank by the Borrowers pursuant to this Agreement, or in connection with the decision of the Bank to enter into this Agreement, to any such Subsidiary or Affiliate of the Bank, it being understood that any such Subsidiary or Affiliate of the Bank receiving such information shall be bound by the provisions of this Section 8.18 as if it were a Bank hereunder. Such authorization shall survive the repayment of the Loans.

8.19 Payment of Debt; Joint and Several Obligations.

The Borrowers shall be jointly and severally liable for the Debt with respect to the Loans under this Agreement and each of the other Loan Documents. Without limiting the generality of the foregoing, each of the Borrowers hereby acknowledges and agrees that any and all actions, inactions or omissions by any one or more, or all, of the Borrowers in connection with, related to or otherwise affecting this Agreement or any of the other Loan Documents with respect to the Loans are the obligations of, and inure to and are binding upon, each and all of the Borrowers, jointly and severally.

8.20 Additional Waivers of the Borrowers.

(a) Each Borrower hereby waives to the full extent permitted by Law any defense it may otherwise have to the payment and performance of the Debt with respect to the

- 70 -

Loans based on any contention that its liability hereunder and under the other Loan Documents with respect to the Loans is limited and not joint and several. Each Borrower acknowledges and agrees that the foregoing waivers and those set forth below serve as a material inducement to the agreement of the Bank to make the Loans, and that the Bank is relying on each specific waiver and all such waivers in entering into this Agreement. The undertakings of each Borrower hereunder secure the Debt of itself and the other Borrowers with respect to the Loans.

(b) Each Borrower further agrees that the Bank may do any of the following without notice to such Borrower and without adversely affecting the validity or enforceability of this Agreement or the Debt with respect to the Loans (or any portion thereof): (i) release, surrender, exchange, compromise or settle the Debt with respect to the Loans or any portion thereof, with respect to any other Borrower; (ii) change, renew or waive the terms of the Debt, or any part thereof with respect to the Loans with respect to any other Borrower; (iii) change, renew or waive the terms of any of the Loan Documents or any other agreements relating to the Debt with respect to the Loans, or any portion thereof, with respect to any other Borrower; (iv) grant any extension or indulgence with respect to the payment or performance of the Debt, or any portion thereof, with respect to the Loans with respect to any other Borrower; (v) enter into any agreement of forbearance with respect to the Debt, or any portion thereof, with respect to the Loans with respect to any other Borrower; and (vi) release, surrender, exchange, impair or compromise any security of any other Borrower held by the Bank for the Debt or any portion thereof with respect to the Loans. Each Borrower agrees that the Bank may do any of the above as the Bank deems necessary or advisable, in the Bank’s sole discretion, without giving notice to any other Borrower, and that such Borrower will remain liable for full payment and performance of the Debt with respect to the Loans.

(c) Each Borrower waives and agrees not to enforce any of the rights of the Bank against any other Borrower or any other obligor of the Debt, or any portion thereof, with respect to the Loans, or any collateral securing the same unless and until all of the Debt with respect to the Loans hall have been indefeasibly paid in full and the Borrowers’ rights to borrower hereunder with respect to the Loans have terminated, including but not limited to any right of such Borrower to be subrogated in whole or in part to any right or claim of the Bank with respect to the Debt or any portion thereof with respect to the Loans. Each Borrower hereby irrevocably agrees that following the occurrence of any Event of Default which has not been waived by the Bank, such Borrower shall not enforce any rights of contribution, indemnity or reimbursement from any other Borrower on account of such Borrower’s payment of the Debt, or any portion thereof, with respect to the Loans unless and until all of the Debt with respect to the Loans shall have been indefeasibly paid in full and the Borrowers’ rights to borrow hereunder have terminated. Each of the Borrowers hereby waives any defenses based on suretyship or impairment of the collateral securing the Loans with respect to the Loans or the like.

8.21 Relative Priority of Security Interests; Limitation of Certain Liabilities.

To the extent any portion of the Debt of a Borrower with respect to the Loans may be determined by final order of a court of competent jurisdiction to be in the nature of the obligations of a surety (the “Suretyship Portion”), any security interests in the assets of such Borrower securing the Suretyship Portion shall be subordinate to the security interests in the assets securing the remaining portion of the Debt with respect to the Loans. If the Suretyship Portion would otherwise

- 71 -

be held or determined to be void, invalid or unenforceable on account of its amount, notwithstanding any other provision of this Agreement to the contrary, the aggregate amount of such liability shall, without any further action by the Bank, the Borrower or any other Persons, be automatically limited and reduced to the highest amount which is valid and enforceable as determined in such action or proceeding.

8.22 Certifications From Bank and Participants.

(a) Tax Withholding. Any assignee or participant of the 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 Bank or assignee or participant of the Bank) agrees that it will deliver to the Borrowers and the Bank 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-8ECI; a Form W-8IMY and the related statements and certifications as required under §1.1441-1(c)(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. Any assignee or participant required to deliver to the Borrowers and the Bank a Withholding Certificate pursuant to the preceding sentence shall deliver such valid Withholding Certificate at least five (5) Business Days before the effective date of such assignment or participation (unless the Bank 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 Bank). Any assignee or participant which so delivers a valid Withholding Certificate further undertakes to deliver to the Borrowers and the Bank 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 Borrowers or the Bank. Notwithstanding the submission of a Withholding Certificate claiming a reduced rate of or exemption from U.S. withholding tax, the Bank 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 Bank is indemnified under § 1.1461-1(e) of the Regulations against any claims and demands of any assignee or participant of the Bank for the amount of any tax it deducts and withholds in accordance with regulations under § 1441 of the Internal Revenue Code.

(b) USA Patriot Act. Any assignee or participant of the 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 Bank the certification, or, if applicable, recertification, certifying that

- 72 -

the 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 ten (10) days after the Closing Date, and (2) at such other times as are required under the USA Patriot Act.

8.23 Amendment and Restatement.

This Agreement amends and restates in its entirety the Existing Agreement. All references to the “Agreement” contained in the Loan Documents delivered in connection with the Existing Agreement or this Agreement shall, and shall be deemed to, refer to this Agreement. Notwithstanding the amendment and restatement of the Existing Agreement by this Agreement, the Debt of the Borrowers outstanding under the Existing Agreement and the Loan Documents as of the Closing Date shall remain outstanding and shall constitute continuing Debt without novation and shall continue as such to be secured by the Collateral. Such Debt shall in all respects be continuing and this Agreement shall not be deemed to evidence or result in a novation or repayment and reborrowing of such Debt. The Liens securing payment of the Debt under the Existing Agreement, as amended and restated in the form of this Agreement, shall in all respects be continuing, securing the payment of all Debt.
