ARTICLE II THE LOANS 2.01 The Loans. Subject to the terms and conditions set forth herein, each Lender severally agrees to make a single loan to the Borrower on the Closing Date in an amount not to exceed such Lender’s Commitment. The Borrowing shall consist of Loans made simultaneously by the Lenders in accordance with their respective Applicable Percentage of the Facility. Amounts borrowed under this Section 2.01 and repaid or prepaid may not be reborrowed. 2.02 Borrowing. (a) The Borrowing, shall be made upon the Borrower’s irrevocable notice to the Administrative Agent, which shall be given pursuant to a Loan Notice. Such Loan Notice must be received by the Administrative Agent not later than 11:00 a.m. three Business Days prior to the Closing Date (or such shorter period as approved by the Required Lenders). Such Loan Notice shall specify (i) the requested date of the Borrowing (which shall be a Business Day and the Closing Date), and (ii) the principal amount of Loans to be borrowed. (b) Following receipt of the Loan Notice, the Administrative Agent shall promptly notify each Lender of the amount of its Applicable Percentage of the Loans. Each Lender shall make the amount of its Loan available to the Administrative Agent in immediately available funds at the Administrative Agent’s Office not later than 11:00 a.m. on the Closing Date. Upon satisfaction of the applicable conditions set forth in Article IV, the Administrative Agent shall make all funds so received available to the Borrower in like funds as received by the Administrative Agent by wire transfer of such funds, in accordance with instructions provided to the Administrative Agent by the Borrower. 2.03 Prepayments. (a) Optional. The Borrower may, upon notice to the Administrative Agent, at any time or from time to time voluntarily prepay Loans in whole or in part; provided that (A) such notice must be received by the Administrative Agent not later than 11:00 a.m. three Business Days prior to any date of prepayment of Loans; and (B) any prepayment of Loans shall be in a principal amount of $1,000,000 or a whole multiple of $500,000 in excess thereof or if less, the entire principal amount thereof then outstanding. Each such notice shall specify the date and amount of such prepayment. The Administrative Agent will promptly notify each Lender of its receipt of each such notice, and of the amount of such Lender’s ratable portion of such prepayment (based on such Lender’s Applicable Percentage). If such notice is given by the Borrower, the Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein. Any prepayment of a Loan shall be accompanied by all accrued interest on the amount prepaid and, if applicable, the Prepayment Premium. Each prepayment of the outstanding Loans pursuant to this Section 2.03(a) shall be applied to the principal repayment installments thereof in inverse order of maturity, and each

-22- such prepayment shall be paid to the Lenders in accordance with their respective Applicable Percentages. (b) Mandatory. (i) If any Loan Party or any of its Subsidiaries Disposes of any property that is permitted by Section 7.05(e) or that is not permitted by Section 7.05, which, in either case, results in the realization by such Person of Net Cash Proceeds, the Borrower shall prepay, or cause to be prepaid, an aggregate principal amount of Loans equal to 100% of such Net Cash Proceeds, immediately upon receipt thereof by such Person (such prepayments to be applied as set forth in clause (vi) below). (ii) Upon the sale or issuance by any Loan Party or any of its Subsidiaries of any of its Equity Interests (other than any sales or issuances of Equity Interests to another Loan Party), the Borrower shall prepay, or cause to be prepaid, an aggregate principal amount of Loans equal to 35% of all Net Cash Proceeds received therefrom, immediately upon receipt thereof by such Loan Party or such Subsidiary (such prepayments to be applied as set forth in clause (vi) below). (iii) Upon the incurrence or issuance by any Loan Party or any of its Subsidiaries of any Indebtedness (other than Indebtedness expressly permitted to be incurred or issued pursuant to Section 7.02), the Borrower shall prepay, or cause to be prepaid, an aggregate principal amount of Loans equal to 100% of all Net Cash Proceeds received therefrom, immediately upon receipt thereof by such Loan Party or such Subsidiary (such prepayments to be applied as set forth in clause (vi) below). (iv) Upon any Extraordinary Receipt received by or paid to or for the account of any Loan Party or any of its Subsidiaries, and not otherwise included in clause (i), (ii), (iii) or (v) of this Section 2.03(b), the Borrower shall prepay, or cause to be prepaid, an aggregate principal amount of Loans equal to 100% of all Net Cash Proceeds received therefrom, immediately upon receipt thereof by such Loan Party or such Subsidiary (such prepayments to be applied as set forth in clause (vi) below); provided, however, that, at the election of the Borrower (as notified by the Borrower to the Administrative Agent on or prior to the date of receipt of such Extraordinary Receipt), and so long as no Default shall have occurred and be continuing, such Loan Party or such Subsidiary may, within 90 days after the receipt of such Net Cash Proceeds, use such cash proceeds to replace or repair the assets in respect of which the Extraordinary Receipts were received or reinvest such cash proceeds in other capital assets used or useful in the business of the Borrower and its Subsidiaries; and provided, further, however, that any Net Cash Proceeds not so applied shall be immediately applied after the expiration of such 90-day period to the prepayment of the Loans as set forth in this Section 2.03(b)(iv); (v) Upon release to any Loan Party or any Subsidiary thereof of any cash or cash equivalents that previously secured any Cash Secured Letters of Credit, the Borrower shall prepay, or cause to be prepaid, an aggregate principal amount of Loans equal to 100% of such cash or cash equivalents, immediately upon receipt thereof by

-23- such Loan Party or such Subsidiary (such prepayments to be applied as set forth in clause (vi) below). (vi) Each prepayment of Loans pursuant to the foregoing provisions of this Section 2.03(b) shall be applied to the principal repayment installments of the Facility in inverse order of maturity. (c) Prepayment Premium. Each prepayment or repayment of Loans that is (or is required to be) made under (i) Section 2.03(a), (ii) Section 2.03(b), or (iii) as a result of acceleration of the Loans under Article VIII, shall be made together with the Prepayment Premium and all unpaid interest on the amount so prepaid or repaid, provided that such Prepayment Premium shall not be due in connection with any prepayment or repayment of Loans (A) made pursuant to Section 2.03(b)(iv) until the aggregate amount of principal repaid or prepaid pursuant to such Section exceeds $1,000,000 or (B) made pursuant to Section 2.03(b)(v) to the extent (and only to the extent) that the amount of such repayment or prepayment is applied to the Required Amortization Amount due on the next Amortization Date in accordance with the definition of “Required Amortization Amount”. Notwithstanding the foregoing, if the Loans are repaid in full on the Maturity Date in accordance with the terms of this Agreement, no Prepayment Premium shall be due in connection therewith. (d) Change of Control Premium. If a Change of Control occurs, the Required Lenders may, at their option and in their sole discretion, instruct the Administrative Agent by written notice to the Borrower to require the Borrower to repay all of the Obligations in cash in an amount equal to 100% of the aggregate unpaid principal amount of the Obligations then outstanding plus the Change of Control Premium (the “Change of Control Prepayment”). The Borrower must pay the Change of Control Prepayment within 10 Business Days of demand therefor by the Administrative Agent. 2.04 Termination of Commitments. The Aggregate Commitments shall be automatically and permanently reduced to zero on the Closing Date after giving effect to the Borrowing made on such date. 2.05 Repayment of Loans. On each Amortization Date, the Borrower shall repay to the Administrative Agent, for the pro rata benefit of the Lenders, the principal of the Loans in an amount equal to the Required Amortization Amount. On the Maturity Date, the Borrower shall repay to the Administrative Agent, for the pro rata benefit of the Lenders, the aggregate principal amount of all Loans outstanding on such date, together with any other Obligations outstanding on such date. 2.06 Interest. (a) Subject to the provisions of Section 2.06(b), each Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Interest Rate. (b) If any amount of principal of any Loan is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise,

-24- such amount shall thereafter bear interest at an interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws. (c) If any amount (other than principal of any Loan) payable by the Borrower under any Loan Document is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, then upon the request of the Required Lenders such amount shall thereafter bear interest at an interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws. (d) Upon the request of the Required Lenders, while any Event of Default exists (other than as set forth in Section 2.06(b)(i) above), the Borrower shall pay interest on the principal amount of all outstanding Obligations hereunder at an interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws. (e) Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable upon demand. (f) Interest on each Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified herein. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any Debtor Relief Law. 2.07 Fees. (a) The Borrower shall pay to the Administrative Agent, for its own account, fees in the amounts and at the times specified in the Agent Fee Letter. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever. (b) The Borrower shall pay to the Lenders, for their own accounts, fees in the amounts and at the times specified in the Lender Fee Letter and such other fees as shall have been separately agreed upon in writing in the amounts and at the times so specified. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever. 2.08 Computation of Interest and Fees. All computations of fees and interest shall be made on the basis of a 360-day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365-day year). Interest shall accrue on each Loan for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid; provided that any Loan that is repaid on the same day on which it is made shall, subject to Section 2.10(a), bear interest for one day. Each determination by the Administrative Agent of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error. 2.09 Evidence of Debt. (a) The Borrowing shall be evidenced by one or more accounts or records maintained by such Lender and by the Administrative Agent in the ordinary course of business. The accounts or records maintained by the Administrative Agent and each Lender shall be

-25- conclusive absent manifest error of the amount of the Borrowing made by the Lenders to the Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender (which may be made through the Administrative Agent), the Borrower shall execute and deliver to such Lender a Note, which shall evidence such Lender’s Loans in addition to such accounts or records. Each Lender may attach schedules to its Note and endorse thereon the date, amount and maturity of its Loans and payments with respect thereto. (b) In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. 2.10 Payments Generally; Administrative Agent’s Clawback. (a) General. All payments to be made by the Borrower shall be made free and clear of and without condition or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein, all payments by the Borrower hereunder shall be made to the Administrative Agent, for the account of the respective Lenders to which such payment is owed, at the Administrative Agent’s Office in Dollars and in immediately available funds not later than 11:00 a.m. on the date specified herein. The Administrative Agent will promptly distribute to each Lender its Applicable Percentage (or other applicable share as provided herein) of such payment in like funds as received by wire transfer to such Lender’s Lending Office. All payments received by the Administrative Agent after 11:00 a.m. shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue. If any payment to be made by the Borrower shall come due on a day other than a Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected on computing interest or fees, as the case may be. (b) Funding by Lenders; Presumption by Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the Closing Date that such Lender will not make available to the Administrative Agent such Lender’s share of the Borrowing to be made on such date, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.02 and may, in reliance upon such assumption, but without any obligation to do so, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount in immediately available funds with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (A) in the case of a payment to be made by such Lender, the Federal Funds , plus any administrative, processing or similar fees customarily charged by the Lenders in connection with the foregoing, and (B) in the case of a payment to be made by the Borrower, the

-26- Interest Rate. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the Borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in the Borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent. (c) Payments by Borrower; Presumptions by Administrative Agent. Unless the Administrative Agent shall have received notice from the Borrower prior to the time at which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, but without any obligation to do so, distribute to the Lenders the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender, in immediately available funds with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the Federal Funds Rate. A notice of the Administrative Agent to any Lender or the Borrower with respect to any amount owing under this subsection (c) shall be conclusive, absent manifest error. (d) Failure to Satisfy Conditions Precedent. If any Lender makes available to the Administrative Agent funds for the Loan to be made by such Lender on the Closing Date as provided in the foregoing provisions of this Article II, and such funds are not made available to the Borrower by the Administrative Agent because the conditions to the Borrowing set forth in Article IV are not satisfied or waived in accordance with the terms hereof, the Administrative Agent shall return such funds (in like funds as received from such Lender) to such Lender, without interest. (e) Obligations of Lenders Several. The obligations of the Lenders hereunder to make Loans and to make payments pursuant to Section 10.04(c) are several and not joint. The failure of any Lender to make any Loan, to fund any such participation or to make any payment under Section 10.04(c) on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so on such date, and no Lender shall be responsible for the failure of any other Lender to so make its Loan, to purchase its participation or to make its payment under Section 10.04(c). (f) Funding Source. Nothing herein shall be deemed to obligate any Lender to obtain the funds for any Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any Loan in any particular place or manner. (g) Insufficient Funds. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, toward payment of fees of the Administrative Agent and the Collateral Agent (including fees of legal counsel) then due hereunder, ratably

-27- among such agents in accordance with the amounts of fees then due to such parties; (ii) second, toward payment of fees of the Lenders then due hereunder, ratably among such parties in accordance with the amounts of fees then due to such parties; and (iii) third, toward payment of interest then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest then due to such parties; and (iii) fourth, toward payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties. 2.11 Sharing of Payments by Lenders. If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of (a) Obligations due and payable to such Lender hereunder and under the other Loan Documents at such time in excess of its ratable share (according to the proportion of (i) the amount of such Obligations due and payable to such Lender at such time to (ii) the aggregate amount of the Obligations due and payable to all Lenders hereunder and under the other Loan Documents at such time) of payments on account of the Obligations due and payable to all Lenders hereunder and under the other Loan Documents at such time obtained by all the Lenders at such time or (b) Obligations owing (but not due and payable) to such Lender hereunder and under the other Loan Documents at such time in excess of its ratable share (according to the proportion of (i) the amount of such Obligations owing (but not due and payable) to such Lender at such time to (ii) the aggregate amount of the Obligations owing (but not due and payable) to all Lenders hereunder and under the other Loan Parties at such time) of payment on account of the Obligations owing (but not due and payable) to all Lenders hereunder and under the other Loan Documents at such time obtained by all of the Lenders at such time then the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of Obligations then due and payable to the Lenders or owing (but not due and payable) to the Lenders, as the case may be, provided that: (i) if any such participations or subparticipations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations or subparticipations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and (ii) the provisions of this Section shall not be construed to (A) apply to any payment made by or on behalf of the Borrower pursuant to and in accordance with the express terms of this Agreement or (B) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans, other than an assignment to the Borrower or any Affiliate thereof (as to which the provisions of this Section shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

-28- 2.12 Right to Extend the Original Maturity Date. (a) The Borrower shall have the right, in its discretion, to be exercised by notice in writing to the Administrative Agent (which notice shall be promptly provided by the Administrative Agent to each Lender), delivered not less than 10 Business Days prior to the Original Maturity Date, to extend the Maturity Date of the Loans to the Extended Maturity Date (any Loans so extended, the “Extended Loans”), so long as: (i) the Filing Date shall have occurred on or before the Original Maturity Date; (ii) the Borrower shall have delivered to the Administrative Agent and the Lenders the financial statements required to be delivered by Section 6.01(a) for the fiscal year ending December 31, 2015; (iii) the representations and warranties of the Borrower and each other Loan Party contained in Article V and the other Loan Documents, are true and correct on and as of the Original Maturity Date, before and after giving effect to the extension of the Loans on such date; (iv) no Default or Event of Default shall have occurred and be continuing on the Original Maturity Date or would occur after giving effect to the extension of the Loans on such date; (v) on or prior to the Original Maturity Date, CCS shall have leased or sold at least one additional refined coal facility to a third party that is not an Affiliate of the Loan Parties that is not leased or sold as of the Closing Date; (vi) the Borrower shall have delivered evidence to the Required Lenders (reasonably acceptable to them), that the Borrower is in compliance with Section 6.15(a) on and as of the Original Maturity Date; and (vii) on or prior to the Original Maturity Date, the Borrower shall have paid to the Lenders, for their own accounts, a fee in an amount equal to 4% of the outstanding Loans held by such Lender as of the Original Maturity Date after giving effect to the Required Amortization Amount required to be paid (and paid) by the Borrower on such date (it being understood, that such fees shall be fully earned when due and shall not be refundable for any reason whatsoever). 2.13 Representation by Lenders. Each of the Lenders represents and warrants to the Borrower that as of the date hereof, such Lender is a “qualified purchaser,” as such term is defined in Section 2(a)(51) of the Investment Company Act of 1940, as amended, and Rules 2a51-1, 2a51-2 and 2a51-3 thereunder.

-29- ARTICLE III TAXES, YIELD PROTECTION AND ILLEGALITY 3.01 Taxes. (a) Payments Free of Taxes; Obligation to Withhold; Payments on Account of Taxes. (i) Any and all payments by or on account of any obligation of any Loan Party hereunder or under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable Laws. If any applicable Laws (as determined in the good faith discretion of the Administrative Agent) require the deduction or withholding of any Tax from any such payment by the Administrative Agent or a Loan Party, then the Administrative Agent or such Loan Party shall be entitled to make such deduction or withholding, upon the basis of the information and documentation to be delivered pursuant to subsection (e) below. (ii) If any Loan Party or the Administrative Agent shall be required by any applicable Laws to withhold or deduct any Taxes from any payment, then (A) such Loan Party or the Administrative Agent, as required by such Laws, shall withhold or make such deductions as are determined by it to be required based upon the information and documentation it has received pursuant to subsection (e) below, (B) such Loan Party or the Administrative Agent, to the extent required by such Laws, shall timely pay the full amount withheld or deducted to the relevant Governmental Authority in accordance with such Laws, and (C) to the extent that the withholding or deduction is made on account of Indemnified Taxes, the sum payable by the applicable Loan Party shall be increased as necessary so that after any required withholding or the making of all required deductions (including deductions applicable to additional sums payable under this Section 3.01) the applicable Recipient receives an amount equal to the sum it would have received had no such withholding or deduction been made. (b) Payment of Other Taxes by the Borrower. Without limiting the provisions of subsection (a) above, the Borrower shall timely pay to the relevant Governmental Authority in accordance with applicable Law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes. (c) Tax Indemnifications. (i) The Borrower shall, and does hereby, indemnify each Recipient, and shall make payment in respect thereof within 10 days after demand therefor, for the full amount of any Indemnified Taxes (including Taxes imposed or asserted on or attributable to amounts payable under this Section 3.01) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the

-30- Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error. (ii) Each Lender shall, and does hereby, severally indemnify, and shall make payment in respect thereof within 10 days after demand therefor, (x) the Administrative Agent against any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), (y) the Administrative Agent and the Borrower, as applicable, against any Taxes attributable to such Lender’s failure to comply with the provisions of Section 10.06(d) relating to the maintenance of a Participant Register and (z) the Administrative Agent against any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender, as the case may be, under this Agreement or any other Loan Document against any amount due to the Administrative Agent under this clause (ii). (d) Evidence of Payments. As soon as practicable after any payment of Taxes by the Borrower to a Governmental Authority as provided in this Section 3.01, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of any return required by Laws to report such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. (e) Status of Lenders; Tax Documentation. (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable Law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 3.01(e)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

-31- (ii) Without limiting the generality of the foregoing, in the event that the Borrower is a U.S. Person, (A) any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax; (B) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable: (1) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed copies of IRS Form W-8BEN-E (or W-8BEN, as applicable) establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN-E (or W-8BEN, as applicable) establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty; (2) executed copies of IRS Form W-8ECI; . (3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit G-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of IRS Form W-8BEN-E (or W-8BEN, as applicable); or (4) to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN-E (or W-8BEN, as applicable), a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-2 or Exhibit G-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign

-32- Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-4 on behalf of each such direct and indirect partner; (C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of any other form prescribed by applicable Law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable Law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and (D) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by Law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement. (iii) Each Lender agrees that if any form or certification it previously delivered pursuant to this Section 3.01 expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so. (f) Treatment of Certain Refunds. Unless required by applicable Laws, at no time shall the Administrative Agent have any obligation to file for or otherwise pursue on behalf of a Lender, or have any obligation to pay to any Lender, any refund of Taxes withheld or deducted from funds paid for the account of such Lender, as the case may be. If any Recipient determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 3.01, it shall pay to the Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 3.01 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) incurred by such Recipient, and without interest (other than any interest paid by the relevant Governmental

-33- Authority with respect to such refund), provided that the Borrower, upon the request of the Recipient, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Recipient in the event the Recipient is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this subsection, in no event will the applicable Recipient be required to pay any amount to the Borrower pursuant to this subsection the payment of which would place the Recipient in a less favorable net after-Tax position than such Recipient would have been in if Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such tax had never been paid. This subsection shall not be construed to require any Recipient to available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrower or any other Person. (g) Survival. Each party’s obligations under this Section 3.01 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Aggregate Commitments and the repayment, satisfaction or discharge of all other Obligations. 3.02 Increased Costs. (a) Increased Costs Generally. If any Change in Law shall: (i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender; or (ii) subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Loan, or of maintaining its obligation to make any such Loan, or to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or any other amount) then, upon request of such Lender, the Borrower will pay to such Lender, such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered. (b) Capital Requirements. If any Lender determines that any Change in Law affecting such Lender or any Lending Office of such Lender or such Lender’s holding company, if any, regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by such Lender, to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy),

-34- then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered. (c) Certificates for Reimbursement. A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company as specified in subsection (a) or (b) of this Section and delivered to the Borrower shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. (d) Delay in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to the foregoing provisions of this Section 3.02 shall not constitute a waiver of such Lender’s right to demand such compensation, provided that the Borrower shall not be required to compensate a Lender pursuant to the foregoing provisions of this Section for any increased costs incurred or reductions suffered more than nine months prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine- month period referred to above shall be extended to include the period of retroactive effect thereof). 3.03 Mitigation Obligations; Replacement of Lenders. (a) Designation of a Different Lending Office. Each Lender may make its Loan to the Borrower through any Lending Office, provided that the exercise of this option shall not affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement. If any Lender requests compensation under Section 3.02, or requires the Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01, then at the request of the Borrower such Lender shall, as applicable, use reasonable efforts to designate a different Lending Office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.01 or 3.02, as the case may be, in the future, and (ii) in each case, would not subject such Lender, as the case may be, to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender, as the case may be. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. (b) Replacement of Lenders. If any Lender requests compensation under Section 3.02, or if the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 3.01, and in each case, such Lender has declined or is unable to designate a different lending office in accordance with Section 3.03(a), the Borrower may replace such Lender in accordance with Section 10.13.

-35- 3.04 Survival.

ARTICLE IX ADMINISTRATIVE AGENT 9.01 Appointment and Authority. (a) Each of the Lenders hereby irrevocably appoints Wilmington Trust, National Association, to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Administrative Agent, the Lenders, and neither the Borrower nor any other Loan Party shall have rights as a third party beneficiary of any of such provisions. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable Law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties. (b) Each of the Lenders hereby irrevocably appoints Wilmington Trust, National Association, as the Collateral Agent and authorizes it to act as the agent of such Lender for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any of the Loan Parties to secure any of the Obligations, together with such powers and discretion as are reasonably incidental thereto. In this connection, the Collateral Agent and any co-agents, sub-agents and attorneys-in-fact appointed by the Collateral Agent pursuant to Section 9.05 for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Collateral Documents, or for exercising any rights and remedies thereunder at the direction of the Administrative Agent), shall be entitled to the benefits of all provisions of this Article IX and Article X (including Section 10.04(c), as though such co-agents, sub-agents and attorneys-in-fact were the “collateral agent” under the Loan Documents) provided to the Administrative Agent as if set forth in full herein with respect thereto. 9.02 Rights as a Lender. If applicable, the Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders. 9.03 Exculpatory Provisions. The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its

-65- duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent: (a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing; (b) shall not have any duty to take any discretionary action or exercise any discretionary powers by consent, designation, specification, requirement or approval of, notice, request or other communication from, or other direction given or action to be undertaken or to be (or not to be) suffered or omitted by the Administrative Agent or to any election, decision, opinion, acceptance, use of judgment, expression of satisfaction or other exercise of discretion, rights or remedies to be made (or not to be made), except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable law, including for the avoidance of doubt any action that may be in violation of the automatic stay under any Debtor Relief Law; and (c) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity. (d) The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 10.01 and 8.02) or (ii) in the absence of its own gross negligence or willful misconduct, as determined by a court of competent jurisdiction by a final and nonappealable judgment. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given to the Administrative Agent by the Borrower or a Lender. (e) The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, or the creation, perfection or priority of any Lien purported to be created by the Collateral Documents, (v) the value or the sufficiency of any Collateral, or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

-66- (f) The Administrative Agent shall not be required to expend or risk any of its own funds or otherwise incur any liability, financial or otherwise, in the performance of any of its duties hereunder or under any other Loan Document. (g) The Administrative Agent shall not be responsible for and makes no representation as to the existence, genuineness, value or protection of any Collateral, for the legality, effectiveness or sufficiency of any Collateral Document, or for the creation, perfection, priority, sufficiency or protection of any liens securing the Notes. (h) For the avoidance of doubt, nothing herein shall require the Administrative Agent to file financing statements or continuation statements, or be responsible for maintaining the security interests purported to be created as described herein (except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder or under any other Loan Document) and such responsibility shall be solely that of the Borrower. (i) The Administrative Agent shall not incur any liability for not performing any act or fulfilling any duty, obligation or responsibility hereunder by reason of any occurrence beyond the control of such Administrative Agent (including but not limited to any act or provision of any present or future law or regulation or governmental authority, any act of God or war, civil unrest, local or national disturbance or disaster, any act of terrorism, or the unavailability of the Federal Reserve Bank wire or facsimile or other wire or communication facility). 9.04 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan that by its terms must be fulfilled to the satisfaction of a Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender unless the Administrative Agent shall have received notice to the contrary from such Lender prior to the making of such Loan. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, at the expense of the Borrower, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. 9.05 Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of

-67- the credit facilities provided for herein as well as activities as Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub- agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub-agents. 9.06 Resignation of Administrative Agent. (a) The Administrative Agent may at any time give notice of its resignation to the Lenders and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Administrative Agent may (but shall not be obligated to) on behalf of the Lenders, appoint a successor Administrative Agent meeting the qualifications set forth above. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date. (b) The Required Lenders may, to the extent permitted by applicable law, by notice in writing to the Borrower and the Administrative Agent remove the Person acting as Administrative Agent and, if no Event of Default shall have occurred and be continuing, with the prior written consent of the Borrower, appoint a successor. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days (or such earlier day as shall be agreed by the Required Lenders) (the “Removal Effective Date”), then such removal shall nonetheless become effective in accordance with such notice on the Removal Effective Date. (c) With effect from the Resignation Effective Date or the Removal Effective Date (as applicable) (1) the retiring or removed Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Administrative Agent on behalf of the Lenders under any of the Loan Documents, the retiring Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed) and (2) except for any indemnity payments or other amounts then owed to the retiring or removed Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender directly, until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for above. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or removed) Administrative Agent (other than as provided in Section 3.01(g) and other than any rights to indemnity payments or other amounts owed to the retiring or removed Administrative Agent as of the Resignation Effective Date or the Removal Effective Date, as applicable), and the retiring or removed Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this Section). The fees payable by the Borrower to a successor

-68- Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring or removed Administrative Agent’s resignation or removal hereunder and under the other Loan Documents, the provisions of this Article and Section 10.04 shall continue in effect for the benefit of such retiring or removed Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring or removed Administrative Agent was acting as Administrative Agent. 9.07 Non-Reliance on Administrative Agent and Other Lenders. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder. 9.08 Administrative Agent May File Proofs of Claim; Credit Bidding. In case of the pendency of any proceeding under any Debtor Relief Law or any other judicial proceeding relative to any Loan Party, the Administrative Agent at the direction of the Required Lenders (irrespective of whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent or the Required Lenders shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise. (a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent under 2.07 and 10.04) allowed in such judicial proceeding; and (b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, if the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Sections 2.07 and 10.04. Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization,

-69- arrangement, adjustment or composition affecting the Obligations or the rights of any Lender to authorize the Administrative Agent to vote in respect of the claim of any Lender or in any such proceeding. The Secured Parties hereby irrevocably authorize the Administrative Agent, at the direction of the Required Lenders, to credit bid all or any portion of the Obligations (including accepting some or all of the Collateral in satisfaction of some or all of the Secured Obligations pursuant to a deed in lieu of foreclosure or otherwise) and in such manner purchase (either directly or through one or more acquisition vehicles) all or any portion of the Collateral (a) at any sale thereof conducted under the provisions of the Bankruptcy Code of the United States, including under Sections 363, 1123 or 1129 of the Bankruptcy Code of the United States, or any similar Laws in any other jurisdictions to which a Loan Party is subject, (b) at any other sale or foreclosure or acceptance of collateral in lieu of debt conducted by (or with the consent or at the direction of) the Administrative Agent (whether by judicial action or otherwise) in accordance with any applicable Law. In connection with any such credit bid and purchase, the Obligations owed to the Secured Parties shall be entitled to be, and shall be, credit bid on a ratable basis (with Obligations with respect to contingent or unliquidated claims receiving contingent interests in the acquired assets on a ratable basis that would vest upon the liquidation of such claims in an amount proportional to the liquidated portion of the contingent claim amount used in allocating the contingent interests) in the asset or assets so purchased (or in the Equity Interests or debt instruments of the acquisition vehicle or vehicles that are used to consummate such purchase). In connection with any such bid (i) the Administrative Agent at the direction of the Required Lenders shall be authorized (but not obligated) to form one or more acquisition vehicles to make a bid, (ii) to adopt documents providing for the governance of the acquisition vehicle or vehicles (provided that any actions by the Administrative Agent with respect to such acquisition vehicle or vehicles, including any disposition of the assets or Equity Interests thereof shall be governed, directly or indirectly, by the vote of the Required Lenders, irrespective of the termination of this Agreement and without giving effect to the limitations on actions by the Required Lenders contained in clauses (a) through (g) of Section 10.01 of this Agreement, (iii) the Administrative Agent at the direction of the Required Lenders shall be authorized to assign the relevant Obligations to any such acquisition vehicle pro rata by the Lenders, as a result of which each of the Lenders shall be deemed to have received a pro rata portion of any Equity Interests and/or debt instruments issued by such an acquisition vehicle on account of the assignment of the Obligations to be credit bid, all without the need for any Secured Party or acquisition vehicle to take any further action, and (iv) to the extent that Obligations that are assigned to an acquisition vehicle are not used to acquire Collateral for any reason (as a result of another bid being higher or better, because the amount of Obligations assigned to the acquisition vehicle exceeds the amount of debt credit bid by the acquisition vehicle or otherwise), such Obligations shall automatically be reassigned to the Lenders pro rata and the Equity Interests and/or debt instruments issued by any acquisition vehicle on account of the Obligations that had been assigned to the acquisition vehicle shall automatically be cancelled, without the need for any Secured Party or any acquisition vehicle to take any further action. 9.09 Collateral and Guaranty Matters. Without limiting the provision of Section 9.08, the Lenders irrevocably authorize the Collateral Agent at the direction of the Required Lenders:

-70- (a) to release any Lien on any property granted to or held by the Collateral Agent under any Loan Document (i) upon termination of the Aggregate Commitments and payment in full of all Obligations (other than contingent indemnification obligations), (ii) that is sold or otherwise disposed of or to be sold or otherwise disposed of as part of or in connection with any sale or other disposition permitted hereunder or under any other Loan Document to a Person that is not a Loan Party, (iii) that constitutes Excluded Property, or (iv) if approved, authorized or ratified in writing in accordance with Section 10.01; and (b) to release any Guarantor from its obligations under the Guaranty if such Person ceases to be a Subsidiary as a result of a transaction permitted under the Loan Documents. Upon request by the Collateral Agent at any time, the Required Lenders will confirm in writing the Collateral Agent’s authority to release or subordinate its interest in particular types or items of property, or to release any Guarantor from its obligations under the Guaranty pursuant to this Section 9.09. In each case as specified in this Section 9.09, the Collateral Agent will, at the Borrower’s expense, execute and deliver to the applicable Loan Party such documents as such Loan Party may reasonably request to evidence the release of such item of Collateral from the assignment and security interest granted under the Collateral Documents or to subordinate its interest in such item, or to release such Guarantor from its obligations under the Guaranty, in each case in accordance with the terms of the Loan Documents and this Section 9.09. The Collateral Agent shall not be responsible for or have a duty to ascertain or inquire into any representation or warranty regarding the existence, value or collectability of the Collateral, the existence, priority or perfection of the Collateral Agent’s Lien thereon, or any certificate prepared by any Loan Party in connection therewith, nor shall the Collateral Agent be responsible or liable to the Lenders for any failure to monitor or maintain any portion of the Collateral. ARTICLE X MISCELLANEOUS 10.01 Amendments, Etc. No amendment or waiver of any provision of this Agreement or any other Loan Document, and no consent to any departure by the Borrower or any other Loan Party therefrom, shall be effective unless in writing signed by the Required Lenders and the Borrower or the applicable Loan Party, as the case may be, and acknowledged by the Administrative Agent, and each such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that no such amendment, waiver or consent shall: (a) waive any condition set forth in Article IV (other than clause (b)(i) or (c) of Article IV) without the written consent of each Lender; (b) extend or increase the Commitment of any Lender (or reinstate any Commitment terminated pursuant to Section 8.02) without the written consent of such Lender; (c) postpone any date fixed by this Agreement or any other Loan Document for any payment (excluding mandatory prepayments) of principal, interest, fees or other amounts

The Administrative Agent or the Borrower may each, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it, provided that approval of such procedures may be limited to particular notices or communications. Unless the Administrative Agent otherwise prescribes, (i) notices and other communications sent to an e-mail address shall be deemed received upon the sender’s receipt of an acknowledgement from the intended recipient (such as by the “return receipt requested” function, as available, return e-mail or other written acknowledgement), and (ii) notices or communications posted to an Internet or intranet website shall be deemed received upon the deemed receipt by the intended recipient at its e-mail address as described in the foregoing clause (i) of notification that such notice or communication is available and identifying the website address therefor; provided that, for both clauses (i) and (ii), if such notice, email or other communication is not sent during the normal business hours of the recipient, such notice, email or communication shall be deemed to have been sent at the opening of business on the next business day for the recipient.

All telephonic notices to and other telephonic communications with the Administrative Agent may be recorded by the Administrative Agent, and each of the parties hereto hereby consents to such recording. 10.03 No Waiver; Cumulative Remedies; Enforcement.

The obligations of the Lenders under this subsection (c) are subject to the provisions of Section 2.10(d). (d) Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable law, the Borrower shall not assert, and hereby waives, and acknowledges that no other Person shall have, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or the use of the proceeds thereof. No Indemnitee referred to in subsection (b) above shall be liable for any damages arising from the use by others of any information or other materials distributed to such party by such Indemnitee through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and/or the Loans at the time owing to it or contemporaneous assignments to related Approved Funds (determined after giving effect to such Assignments) that equal at least the amount specified in paragraph (b)(i)(B) of this Section in the aggregate or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

-77- (B) in any case not described in subsection (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment, determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date, shall not be less than $1,000,000, unless the Required Lenders and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consent (each such consent not to be unreasonably withheld or delayed). (ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loans or the Commitment assigned; (iii) Required Consents. No consent shall be required for any assignment except to the extent required by subsection (b)(i)(B) of this Section and, in addition: (A) the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (1) an Event of Default has occurred and is continuing at the time of such assignment or (2) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within five (5) Business Days after having received notice thereof; and (B) the consent of the Required Lenders (such consent not to be unreasonably withheld or delayed) shall be required if such assignment is to a Person that is not a Lender, an Affiliate of such Lender or an Approved Fund with respect to such Lender. (iv) Assignment and Assumption. The parties to each assignment shall execute and deliver to the Administrative Agent (A) an Assignment and Assumption, (B) the assignee’s Administrative Questionnaire and U.S. tax withholding form in accordance with Section 3.03(e) and (C) a processing and recordation fee in the amount of $3,500; provided, however, that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment. The assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire. (v) No Assignment to Certain Persons. No such assignment shall be made (A) to the Borrower or any of the Borrower’s Affiliates or Subsidiaries, or (B) to a natural Person (or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of a natural Person).

-78- (vi) Subject to acceptance and recording thereof by the Administrative Agent pursuant to subsection (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 3.01, 3.02, 3.04 and 10.04 with respect to facts and circumstances occurring prior to the effective date of such assignment. Upon request, the Borrower (at its expense) shall execute and deliver a Note to the assignee Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this subsection shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with subsection (d) of this Section. (c) Register. The Administrative Agent, acting solely for this purpose as a non-fiduciary agent of the Borrower, shall maintain at the Administrative Agent’s Office a copy of each Assignment and Assumption delivered to it (or the equivalent thereof in electronic form) and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts (and stated interest) of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice. (d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural Person, or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of a natural Person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 10.04(c) without regard to the existence of any participation. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification described in the first proviso

-79- to Section 10.01 that affects such Participant. The Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.01 and 3.02 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section (it being understood that the documentation required under Section 3.01(e) shall be delivered to the Lender who sells the participation) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant (A) agrees to be subject to the provisions of Sections 3.02 and 10.13 as if it were an assignee under paragraph (b) of this Section and (B) shall not be entitled to receive any greater payment under Sections 3.01 or 3.02, with respect to any participation, than the Lender from whom it acquired the applicable participation would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower’s request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 3.02 with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.08 as though it were a Lender; provided that such Participant agrees to be subject to Section 2.11 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non- fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103- 1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register. (e) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Note, if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. 10.07 Treatment of Certain Information; Confidentiality. Each of the Administrative Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its Related Parties (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent required or requested by any regulatory authority purporting to have jurisdiction over such Person or its Related Parties (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws

-80- or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights and obligations under this Agreement or (ii) any actual or prospective party (or its Related Parties) to any swap, derivative or other transaction under which payments are to be made by reference to the Borrower and its obligations, this Agreement or payments hereunder, (g) on a confidential basis to (i) any rating agency in connection with rating the Borrower or its Subsidiaries or the credit facilities provided hereunder or (ii) the CUSIP Service Bureau or any similar agency in connection with the issuance and monitoring of CUSIP numbers of other market identifiers with respect to the credit facilities provided hereunder, (h) with the consent of the Borrower or (i) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, any Lender, or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrower. In addition, the Administrative Agent and the Lenders may disclose the existence of this Agreement and information about this Agreement to market data collectors, similar service providers to the lending industry and service providers to the Agents and the Lenders in connection with the administration of this Agreement, the other Loan Documents, and the Commitments. For purposes of this Section, “Information” means all information received from the Borrower or any Subsidiary relating to the Borrower or any Subsidiary or any of their respective businesses, other than any such information that is available to the Administrative Agent, any Lender on a nonconfidential basis prior to disclosure by the Borrower or any Subsidiary, provided that, in the case of information received from the Borrower or any Subsidiary after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information. Each of the Administrative Agent and the Lenders acknowledges that (a) the Information may include material non-public information concerning the Borrower or a Subsidiary, as the case may be, (b) it has developed compliance procedures regarding the use of material non- public information and (c) it will handle such material non-public information in accordance with applicable Law, including United States Federal and state securities Laws. 10.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender or any such Affiliate to or for the credit or the account of the Borrower or any other Loan Party against any and all of the obligations of the Borrower or such Loan Party now or hereafter existing under this Agreement or any other Loan Document to such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement or any other Loan Document and

-81- although such obligations of the Borrower or such Loan Party may be contingent or unmatured or are owed to a branch or office or Affiliate of such Lender different from the branch, office or Affiliate holding such deposit or obligated on such indebtedness. The rights of each Lender and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender or its Affiliates may have. Each Lender agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff and application. 10.09 Interest Rate Limitation. Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable Law (the “Maximum Rate”). If the Administrative Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans or, if it exceeds such unpaid principal, refunded to the Borrower. In determining whether the interest contracted for, charged, or received by the Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable Law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder. 10.10 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent or any Lender, constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Article IV, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic imaging means (e.g. “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart of this Agreement. 10.11 Survival of Representations and Warranties. All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive the execution and delivery hereof and thereof. Such representations and warranties have been or will be relied upon by the Administrative Agent and each Lender, regardless of any investigation made by the Administrative Agent or any Lender or on their behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default at the time of the Borrowing, and shall continue in full force and effect as long as any Loan or any other Obligation hereunder shall remain unpaid or unsatisfied.

-82- 10.12 Severability. If any provision of this Agreement or the other Loan Documents is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Agreement and the other Loan Documents shall not be affected or impaired thereby and (b) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 10.13 Replacement of Lenders. If the Borrower is entitled to replace a Lender pursuant to the provisions of Section 3.03, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 10.06), all of its interests, rights (other than its existing rights to payments pursuant to Sections 3.01 and 3.02) and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that: (a) the Borrower shall have paid to the Administrative Agent the assignment fee (if any) specified in Section 10.06(b); (b) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts); (c) in the case of any such assignment resulting from a claim for compensation under Section 3.02 or payments required to be made pursuant to Section 3.01, such assignment will result in a reduction in such compensation or payments thereafter; and (d) such assignment does not conflict with applicable Laws. A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply. 10.14 Governing Law; Jurisdiction; Etc. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND ANY CLAIMS, CONTROVERSY, DISPUTE OR CAUSE OF ACTION (WHETHER IN CONTRACT OR TORT OR OTHERWISE) BASED UPON, ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT (EXCEPT, AS TO ANY OTHER LOAN DOCUMENT, AS EXPRESSLY SET FORTH THEREIN) AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

EXHIBIT E Guaranty [Attached]

CONTINUING GUARANTY FOR VALUE RECEIVED, the sufficiency of which is hereby acknowledged, and in consideration of credit and/or financial accommodation heretofore or hereafter from time to time made or granted to ADVANCED EMISSIONS SOLUTIONS, INC. (the “Borrower”) by the Lenders (as defined in that certain Credit Agreement, dated as of the date hereof (as amended, modified, extended, restated, renewed, replaced or supplemented from time to time, the “Credit Agreement”; capitalized terms used and not otherwise defined herein shall have the meanings ascribed to such terms in the Credit Agreement), among the Borrower, the Lenders party thereto and WILMINGTON TRUST, NATIONAL ASSOCIATION, as administrative agent (in such capacity, the “Administrative Agent”) and collateral agent for the Secured Parties), the undersigned Guarantor (whether one or more, the “Guarantor”, and if more than one, jointly and severally) hereby furnishes its guaranty in favor of the Administrative Agent, for the benefit of the Secured Parties, as follows: 1. Guaranty. The Guarantor hereby unconditionally and irrevocably guarantees the full and prompt payment when due, whether at stated maturity, by required prepayment, upon acceleration, demand or otherwise, and at all times thereafter, of the Guaranteed Obligations (as hereafter defined) and the punctual performance of all of the terms contained in the documents executed by the Borrower in connection with the Guaranteed Obligations. This Guaranty is a guaranty of payment and performance and is not merely a guaranty of collection. As used herein, the term “Guaranteed Obligations” means any and all Obligations of the Borrower and the other Loan Parties arising under the Credit Agreement and any other Loan Document. Without limiting the generality of the foregoing, the Guaranteed Obligations shall include any such indebtedness, obligations, and liabilities which may be or hereafter become unenforceable or shall be an allowed or disallowed claim under any Debtor Relief Law, and shall include interest that accrues after the commencement by or against the Borrower of any proceeding under any Debtor Relief Laws. Anything contained herein to the contrary notwithstanding, the obligations of the Guarantor hereunder at any time shall be limited to an aggregate amount equal to the largest amount that would not render its obligations hereunder subject to avoidance as a fraudulent transfer or conveyance under Section 548 of the Bankruptcy Code (Title 11, United States Code) or any comparable provisions of any similar federal or state law. 2. No Setoff or Deductions; Taxes; Payments. The Guarantor shall make all payments hereunder without setoff or counterclaim and free and clear of and without deduction for any taxes, levies, imposts, duties, charges, fees, deductions, withholdings, compulsory loans, restrictions or conditions of any nature now or hereafter imposed or levied by any jurisdiction or any political subdivision thereof or taxing or other authority therein unless the Guarantor is compelled by law to make such deduction or withholding. If any such obligation (other than one arising with respect to taxes based on or measured by the income or profits of any Secured Party) is imposed upon the Guarantor with respect to any amount payable by it hereunder, the Guarantor will pay to the Administrative Agent, for the account of the applicable Secured Party, on the date on which such amount is due and payable hereunder, such additional amount in U.S. dollars as shall be necessary to enable such Secured Party to receive the same net amount which such Secured Party would have received on such due date had no such obligation been imposed upon the Guarantor. The Guarantor will deliver promptly to the Administrative Agent certificates or other valid vouchers for all taxes or other charges deducted from or paid with respect to payments made by the Guarantor hereunder. The obligations of the Guarantor under this paragraph shall survive the payment in full of the Guaranteed Obligations and termination of this Guaranty. 3. Rights of Secured Parties. The Guarantor consents and agrees that the Administrative Agent and the other Secured Parties may, at any time and from time to time, without notice or demand, and without affecting the enforceability or continuing effectiveness hereof, in each case, in accordance with the Loan Documents: (a) amend, extend, renew, compromise, discharge, accelerate or otherwise #4985373.4

2 change the time for payment or the terms of the Guaranteed Obligations or any part thereof; (b) take, hold, exchange, enforce, waive, release, fail to perfect, sell, or otherwise dispose of any security for the payment of this Guaranty or any Guaranteed Obligations; (c) apply such security and direct the order or manner of sale thereof as the Administrative Agent may determine; and (d) release or substitute one or more of any endorsers or other guarantors of any of the Guaranteed Obligations. Without limiting the generality of the foregoing, the Guarantor consents to the taking of, or failure to take, any action which might in any manner or to any extent vary the risks of the Guarantor under this Guaranty or which, but for this provision, might operate as a discharge of the Guarantor. 4. Certain Waivers. The Guarantor waives to the fullest extent permitted by law (a) any defense arising by reason of any disability or other defense of the Borrower or any other guarantor, or the cessation from any cause whatsoever (including any act or omission of any Secured Party exceed or are more burdensome than those of the Borrower) (other than the defense that the Guaranteed Obligations have been fully performed and indefeasibly paid in full in cash); (c) the benefit of any statute of limitations affecting the Guarantor’s liability hereunder; (d) any right to require the Administrative Agent or any other Secured Party to proceed against the Borrower, proceed against or exhaust any security for the Guaranteed Obligations, or pursue any other remedy in the Administrative Agent’s or such other Secured Party’s power whatsoever and any defense based upon the doctrines of marshalling of assets or of election of remedies; (e) any benefit of and any right to participate in any security now or hereafter held by the Administrative Agent or any other Secured Party; (f) any fact or circumstance related to the Guaranteed Obligations which might otherwise constitute a defense to the obligations of the Guarantor under this Guaranty (other than the defense that the Guaranteed Obligations have been fully performed and indefeasibly paid in full in cash) and (g) any and all other defenses or benefits that may be derived from or afforded by applicable law limiting the liability of or exonerating guarantors or sureties, other than the defense that the Guaranteed Obligations have been fully performed and indefeasibly paid in full in cash. The Guarantor expressly waives all presentments, demands for payment or performance, notices of nonpayment or nonperformance, protests, notices of protest, notices of dishonor and all other notices or demands of any kind or nature whatsoever with respect to the Guaranteed Obligations (except to the extent the same is expressly required under the terms of the Loan Documents), and all notices of acceptance of this Guaranty or of the existence, creation or incurrence of new or additional Guaranteed Obligations. This Guaranty shall not be affected by the genuineness, validity, regularity or enforceability of the Guaranteed Obligations or any instrument or agreement evidencing any Guaranteed Obligations, or by the existence, validity, enforceability, perfection, non-perfection or extent of any collateral therefor, or by any fact or circumstance relating to the Guaranteed Obligations which might otherwise constitute a defense to the obligations of the Guarantor under this Guaranty, and the Guarantor hereby irrevocably waives any defenses it may now have or hereafter acquire in any way relating to any or all of the foregoing. 5. Obligations Independent. The obligations of the Guarantor hereunder are those of primary obligor, and not merely as surety, and are independent of the Guaranteed Obligations and the obligations of any other guarantor, and a separate action may be brought against the Guarantor to enforce this Guaranty whether or not the Borrower or any other person or entity is joined as a party. 6. Subrogation. The Guarantor shall not exercise any right of subrogation, contribution, indemnity, reimbursement or similar rights with respect to any payments it makes under this Guaranty until all of the Guaranteed Obligations and any amounts payable under this Guaranty have been indefeasibly paid and performed in full, no Lender has any Commitment under the Credit Agreement and no Loan or other Obligation under the Credit Agreement remains unpaid or unsatisfied. If any amounts are paid to the Guarantor in violation of the foregoing limitation, then such amounts shall be held in trust

3 for the benefit of the Administrative Agent, for the benefit of the Secured Parties, and shall forthwith be paid to the Administrative Agent to reduce the amount of the Guaranteed Obligations, whether matured or unmatured. 7. Termination; Reinstatement. This Guaranty is a continuing and irrevocable guaranty of all Guaranteed Obligations now or hereafter existing and shall remain in full force and effect until termination of the Aggregate Commitments and payment in full of all Guaranteed Obligations (other than contingent indemnification obligations). Notwithstanding the foregoing, this Guaranty shall be revived if any payment by or on behalf of the Borrower or the Guarantor is made, or any Secured Party exercises its right of setoff, in respect of the Guaranteed Obligations, and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by such Secured Party in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Laws or otherwise, all as if such payment had not been made or such setoff had not occurred and whether or not such Secured Party is in possession of or has released this Guaranty and regardless of any prior revocation, rescission, termination or reduction. The obligations of the Guarantor under this paragraph shall survive termination of this Guaranty. 8. Subordination. The Guarantor hereby subordinates the payment of all obligations and indebtedness of the Borrower owing to the Guarantor, whether now existing or hereafter arising, including but not limited to any obligation of the Borrower to the Guarantor as subrogee of the Secured Parties or resulting from the Guarantor’s performance under this Guaranty, to the indefeasible payment in full in cash of all Guaranteed Obligations. If the Administrative Agent so requests, any such obligation or indebtedness of the Borrower to the Guarantor shall be enforced and performance received by the Guarantor as trustee for the Administrative Agent and the proceeds thereof shall be paid over to the Administrative Agent, for the benefit of the Secured Parties, on account of the Guaranteed Obligations, but without reducing or affecting in any manner the liability of the Guarantor under this Guaranty. 9. Stay of Acceleration. In the event that acceleration of the time for payment of any of the Guaranteed Obligations is stayed, in connection with any case commenced by or against the Guarantor or the Borrower under any Debtor Relief Laws, or otherwise, all such amounts shall nonetheless be payable by the Guarantor immediately upon demand by the Administrative Agent. 10. Expenses. The Guarantor shall pay on demand all out-of-pocket expenses (including reasonable attorneys’ fees and expenses) in any way relating to the enforcement or protection of the Secured Parties’ rights under this Guaranty or in respect of the Guaranteed Obligations, including any incurred during any “workout” or restructuring in respect of the Guaranteed Obligations and any incurred in the preservation, protection or enforcement of any rights of the Secured Parties in any proceeding under any Debtor Relief Laws. The obligations of the Guarantor under this paragraph shall survive the payment in full of the Guaranteed Obligations and termination of this Guaranty. 11. Miscellaneous. To the extent not prohibited by applicable law, the Administrative Agent’s books and records showing the amount of the Guaranteed Obligations shall be admissible in evidence in any action or proceeding, and shall be binding upon the Guarantor and conclusive, absent manifest error, for the purpose of establishing the amount of the Guaranteed Obligations. No provision of this Guaranty may be waived, amended, supplemented or modified, except by a written instrument executed by the Administrative Agent, with Required Lenders approval in accordance with the Credit Agreement, and the Guarantor. No failure by any Secured Party to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy or power hereunder preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies herein provided are cumulative and not

4 exclusive of any remedies provided by law or in equity. The unenforceability or invalidity of any provision of this Guaranty shall not affect the enforceability or validity of any other provision herein. Unless otherwise agreed by the applicable Secured Party and the Guarantor in writing, this Guaranty is not intended to supersede or otherwise affect any other guaranty now or hereafter given by the Guarantor for the benefit of such Secured Party or any term or provision thereof. 12. Condition of Borrower. The Guarantor acknowledges and agrees that it has the sole responsibility for, and has adequate means of, obtaining from the Borrower and any other guarantor such information concerning the financial condition, business and operations of the Borrower and any such other guarantor as the Guarantor requires, and that the Secured Parties have no duty, and the Guarantor is not relying on the Secured Parties at any time, to disclose to the Guarantor any information relating to the business, operations or financial condition of the Borrower or any other guarantor (the guarantor waiving any duty on the part of the Secured Parties to disclose such information and any defense relating to the failure to provide the same). 13. Setoff. If and to the extent any payment is not made when due hereunder, any Secured Party may setoff and charge from time to time any amount so due against any or all of the Guarantor’s accounts or deposits with such Secured Party. 14. Representations and Warranties. The Guarantor represents and warrants that (a) it is organized and resident in the United States of America; (b) it is duly organized and in good standing under the laws of the jurisdiction of its organization and has full capacity and right to make and perform this Guaranty, and all necessary authority has been obtained; (c) this Guaranty constitutes its legal, valid and binding obligation enforceable in accordance with its terms; (d) the making, existence, and performance of this Guaranty does not and will not violate the provisions of any applicable law, regulation or order, and does not and will not result in the breach of, or constitute a default or require any consent under, any material agreement, instrument, or document to which it is a party or by which it or any of its property may be bound or affected; and (e) all consents, approvals, licenses and authorizations of, and filings and registrations with, any governmental authority required under applicable law and regulations for the making and performance of this Guaranty have been obtained or made and are in full force and effect. 15. GOVERNING LAW; Assignment; Jurisdiction; Notices. THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK. This Guaranty shall (a) bind the Guarantor and its successors and assigns, provided that the Guarantor may not assign its rights or obligations under this Guaranty without the prior written consent of the Administrative Agent, with Required Lenders approval (and any attempted assignment without such consent shall be void), and (b) inure to the benefit of the Administrative Agent and its successors and assigns, in each case for the benefit of the Secured Parties, and the Administrative Agent may, without notice to the Guarantor and without affecting the Guarantor’s obligations hereunder, assign, sell or grant participations in the Guaranteed Obligations and this Guaranty, in whole or in part.

No Grantor has authenticated any agreement authorizing any secured party thereunder to file a financing statement, except to perfect Permitted Liens. The taking possession by the Collateral Agent of the certificated securities (if any) evidencing the Pledged Equity and all other Instruments constituting Collateral will perfect and establish the first priority of the Collateral Agent’s security interest in all the Pledged Equity evidenced by such certificated securities and such Instruments.

(i) Not without executing and delivering, or causing to be executed and delivered, to the Collateral Agent such agreements, documents and instruments as the Collateral Agent may reasonably require, issue or acquire any Pledged Equity consisting of an interest in a partnership or a limited liability company that (A) is dealt in or traded on a securities exchange or in a securities market, (B) by its terms expressly provides that it is a Security governed by Article 8 of the UCC, (C) is an Investment Company Security, (D) is held in a Securities Account or (E) constitutes a Security or a Financial Asset.

(ii) Not make any assignment or agreement in conflict with the security interest in the Copyrights of each Grantor hereunder (except as permitted by the Credit Agreement).

(o) Further Assurances. (i) Promptly upon the request of the Collateral Agent and at the sole expense of the Grantors, duly execute and deliver, and have recorded, such further instruments and documents and take such further actions as the Collateral Agent may reasonably request for the purpose of obtaining or preserving the full benefits of this Agreement and of the rights and powers herein granted (subject, for the avoidance of doubt, to the express exceptions set forth herein), including, without limitation, (A) with respect to Government Contracts, assignment agreements and notices of assignment, in form and substance satisfactory to the Collateral Agent, duly executed by any Grantors party to such Government Contract in compliance with the Assignment of Claims Act (or analogous state applicable Law), and (B) all applications, certificates, instruments, registration statements, and all other documents and papers the Collateral Agent may reasonably request and as may be required by law in connection with the obtaining of any consent, approval, registration, qualification, or authorization of any Person deemed necessary or appropriate for the effective exercise of any rights under this Agreement; provided that no Grantor shall be required to take any action to perfect a security interest in any Collateral that the Collateral Agent reasonably determines that the costs and burdens to the Grantors of perfecting a security interest in such Collateral (including any applicable stamp, intangibles or other taxes) are excessive in relation to the value to the Secured Parties afforded thereby and, for the avoidance of doubt, the Grantors shall not be required to seek or obtain the consent, approval, waiver or acknowledgment of any contractual counterparty or other third party with respect to the grant or enforcement of any Collateral, while no Event of Default is continuing, except as otherwise expressly agreed in the Credit Agreement or herein.

17 or amendments thereof or supplements thereto or other instruments as the Collateral Agent may from time to time deem necessary or appropriate in order to perfect and maintain the security interests granted hereunder in accordance with the UCC, which such financing statements may describe the Collateral in the same manner as described herein or may contain an indication or description of Collateral that describes such property in any other manner as necessary, advisable or prudent to ensure the perfection of the security interest in the Collateral granted herein, including, without limitation, describing such property as “all assets, whether now owned or hereafter acquired” or “all personal property, whether now owned or hereafter acquired.” 6. Advances. On failure of any Grantor to perform any of the covenants and agreements contained herein or in any other Loan Document, the Collateral Agent may, but shall have no obligation to, perform the same and in so doing may expend such sums as the Collateral Agent may reasonably deem advisable in the performance thereof, including, without limitation, the payment of any insurance premiums, the payment of any taxes, a payment to obtain a release of a Lien or potential Lien, expenditures made in defending against any adverse claim and all other expenditures which the Collateral Agent may make for the protection of the security hereof or which may be compelled to make by operation of Law.

No such performance of any covenant or agreement by the Collateral Agent on behalf of any Grantor, and no such advance or expenditure therefor, shall relieve the Grantors of any Default or Event of Default. The Collateral Agent may make any payment hereby authorized in accordance with any xxxx, statement or estimate procured from the appropriate public office or holder of the claim to be discharged without inquiry into the accuracy of such xxxx, statement or estimate or into the validity of any tax assessment, sale, forfeiture, tax lien, title or claim, except to the extent such payment is being contested in good faith by a Grantor in appropriate proceedings and against which adequate reserves are being maintained in accordance with GAAP. 7. Remedies. (a) General Remedies. Upon the occurrence of an Event of Default and during continuation thereof, the Collateral Agent on behalf of the Secured Parties shall have, in addition to the rights and remedies provided herein, in the Loan Documents, in any other documents relating to the Obligations, or by any applicable Law (including, but not limited to, levy of attachment, garnishment and the rights and remedies set forth in the UCC of the jurisdiction applicable to the affected Collateral), the rights and remedies of a secured party under the UCC (regardless of whether the UCC is the law of the jurisdiction where the rights and remedies are asserted and regardless of whether the UCC applies to the affected Collateral), and further, the Collateral Agent may, with or without judicial process or the aid and assistance of others, (i) enter on any premises on which any of the Collateral may be located and, without resistance or interference by the Grantors, take possession of the Collateral, (ii) dispose of any Collateral on any such premises, (iii) require the Grantors to assemble and make available to the Collateral Agent at the expense of the Grantors any Collateral at any place and time designated by the Collateral Agent which is reasonably convenient to both parties, (iv) remove any Collateral from any such premises for the

18 purpose of effecting sale or other disposition thereof, and (v) without demand and without advertisement, notice, hearing or process of law, all of which each of the Grantors hereby waives to the fullest extent permitted by applicable Law, at any place and time or times, sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels any or all Collateral held by or for it at public or private sale (which in the case of a private sale of Pledged Equity, shall be to a restricted group of purchasers who will be obligated to agree, among other things, to acquire such securities for their own account, for investment and not with a view to the distribution or resale thereof), at any exchange or broker’s board or elsewhere, by one or more contracts, in one or more parcels, for money, upon credit or otherwise, at such prices and upon such terms as the Collateral Agent deems advisable (subject to any and all mandatory legal requirements). Each Grantor acknowledges that any such private sale may be at prices and on terms less favorable to the seller than the prices and other terms which might have been obtained at a public sale and, notwithstanding the foregoing, agrees that such private sale shall be deemed to have been made in a commercially reasonable manner and, in the case of a sale of Pledged Equity, that the Collateral Agent shall have no obligation to delay sale of any such securities for the period of time necessary to permit the Issuer of such securities to register such securities for public sale under the Securities Act of 1933. The Collateral Agent or any other Secured Party shall have the right upon any such public sale or sales, and, to the extent permitted by applicable Law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold. Neither the Collateral Agent’s compliance with applicable Law nor its disclaimer of warranties relating to the Collateral shall be considered to adversely affect the commercial reasonableness of any sale. To the extent the rights of notice cannot be legally waived hereunder, each Grantor agrees that any requirement of reasonable notice shall be met if such notice, specifying the place of any public sale or the time after which any private sale is to be made, is personally served on or mailed, postage prepaid, to the Borrower in accordance with the notice provisions of Section 10.02 of the Credit Agreement, at least 10 days before the time of sale or other event giving rise to the requirement of such notice. Each Grantor further acknowledges and agrees that any offer to sell any Pledged Equity which has been (A) publicly advertised on a bona fide basis in a newspaper or other publication of general circulation in the financial community of New York, New York (to the extent that such offer may be advertised without prior registration under the Securities Act of 1933), or (B) made privately in the manner described above shall be deemed to involve a “public sale” under the UCC, notwithstanding that such sale may not constitute a “public offering” under the Securities Act of 1933, and the Collateral Agent may, in such event, bid for the purchase of such securities. The Collateral Agent shall not be obligated to make any sale or other disposition of the Collateral regardless of notice having been given. To the extent permitted by applicable Law, any Secured Party may be a purchaser at any such sale. To the extent permitted by applicable Law, each of the Grantors hereby waives all of its rights of redemption with respect to any such sale. Subject to the provisions of applicable Law, the Collateral Agent may postpone or cause the postponement of the sale of all or any portion of the Collateral by announcement at the time and place of such sale, and such sale may, without further notice, to the extent permitted by Law, be made at the time and place to which the sale was postponed, or the Collateral Agent may further postpone such sale by

19 announcement made at such time and place. To the extent permitted by applicable Law, each Grantor waives all claims, damages and demands it may acquire against the Collateral Agent or any other Secured Party arising out of the exercise by them of any rights hereunder, except to the extent any such claims, damages or demands result solely from the gross negligence or willful misconduct of the Collateral Agent or any other Secured Party as determined by a final non-appealable judgment of a court of competent jurisdiction, in each case against whom such claim is asserted. Each Grantor agrees that the internet shall constitute a “place” for purposes of Section 9-610(b) of the UCC and that any sale of Collateral to a licensor pursuant to the terms of a license agreement between such licensor and a Grantor is sufficient to constitute a commercially reasonable sale (including as to method, terms, manner, and time) within the meaning of Section 9-610 of the UCC. (b) Remedies Relating to Accounts. (i) Upon the occurrence of an Event of Default and during continuation thereof, whether or not the Collateral Agent has exercised any or all of its rights and remedies hereunder, (A) at the request of the Collateral Agent, each Grantor shall notify its Account Debtors and parties to the Material Contracts subject to a security interest hereunder that such Accounts and the Material Contracts have been assigned to the Collateral Agent, for the benefit of the Secured Parties, and promptly upon request of the Collateral Agent, instruct all account debtors to remit all payments in respect of Accounts to a mailing location selected by the Collateral Agent, and (B) the Collateral Agent shall have the right to enforce any Grantor’s rights against its customers and account debtors, and the Collateral Agent or its designee may notify any Grantor’s customers and account debtors that the Accounts of such Grantor have been assigned to the Collateral Agent or of the Collateral Agent’s security interest therein, and may (either in its own name or in the name of a Grantor or both) demand, collect (including without limitation by way of a lockbox arrangement), receive, take receipt for, sell, xxx for, compound, settle, compromise and give acquittance for any and all amounts due or to become due on any Account, and file any claim or take any other action or proceeding to protect and realize upon the security interest of the Secured Parties in the Accounts. (ii) Each Grantor acknowledges and agrees that the Proceeds of its Accounts remitted to or on behalf of the Collateral Agent in accordance with the provisions hereof shall be solely for the Collateral Agent’s own convenience and that such Grantor shall not have any right, title or interest in such Accounts or in any such other amounts except as expressly provided herein. Neither the Collateral Agent nor the other Secured Parties shall have any liability or responsibility to any Grantor for acceptance of a check, draft or other order for payment of money bearing the legend “payment in full” or words of similar import or any other restrictive legend or endorsement or be responsible for determining the correctness of any remittance. (iii) Upon the occurrence of an Event of Default and during continuation thereof, (A) the Collateral Agent shall have the right, but not the obligation, to make

20 test verifications of the Accounts in any manner and through any medium that it reasonably considers advisable, and the Grantors shall furnish all such assistance and information as the Collateral Agent may require in connection with such test verifications, (B) upon the Collateral Agent’s request and at the expense of the Grantors, the Grantors shall cause independent public accountants or others satisfactory to the Lenders to furnish to the Collateral Agent reports showing reconciliations, aging and test verifications of, and trial balances for, the Accounts and (C) the Collateral Agent in its own name or in the name of others may communicate with account debtors on the Accounts to verify with them to the Collateral Agent’s satisfaction the existence, amount and terms of any Accounts. (iv) Upon the request of the Collateral Agent, each Grantor shall forward to the Collateral Agent, on the last Business Day of each week, deposit slips related to all cash, money, checks or any other similar items of payment received by the Grantor during such week, and, if requested by the Collateral Agent, copies of such checks or any other similar items of payment, together with a statement showing the application of all payments on the Collateral during such week and a collection report with regard thereto, in form and substance satisfactory to the Lenders. (c) Deposit Accounts/Securities Accounts. Upon the occurrence of an Event of Default and during continuation thereof, the Collateral Agent may prevent withdrawals or other dispositions of funds in Deposit Accounts and Securities Accounts that are (i) subject to control agreements (in accordance with the terms thereof) or (ii) held with any Secured Party. (d) Investment Property/Pledged Equity. Upon the occurrence of an Event of Default and during the continuation thereof: the Collateral Agent shall have the right to receive any and all cash dividends, payments or distributions made in respect of any Investment Property or Pledged Equity or other Proceeds paid in respect of any Investment Property or Pledged Equity, and any or all of any Investment Property or Pledged Equity may, at the option of the Collateral Agent, be registered in the name of the Collateral Agent or its nominee, and the Collateral Agent or its nominee may thereafter exercise (i) all voting, corporate and other rights pertaining to such Investment Property, or any such Pledged Equity, at any meeting of shareholders, partners or members of the relevant Issuers or otherwise and (ii) any and all rights of conversion, exchange and subscription and any other rights, privileges or options pertaining to such Investment Property or Pledged Equity as if it were the absolute owner thereof (including, without limitation, the right to exchange any and all of the Investment Property or Pledged Equity upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the corporate, partnership or limited liability company structure of any Issuer or upon the exercise by any Grantor or the Collateral Agent of any right, privilege or option pertaining to such Investment Property or Pledged Equity, and in connection therewith, the right to deposit and deliver any and all of the Investment Property or Pledged Equity with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Collateral Agent may determine), all without liability except to account for property actually received by it; but the Collateral Agent shall have no duty to any Grantor to exercise any such right,

21 privilege or option and the Collateral Agent and the other Secured Parties shall not be responsible for any failure to do so or delay in so doing. In furtherance thereof, each Grantor hereby authorizes and instructs each Issuer with respect to any Collateral consisting of Investment Property and/or Pledged Equity to (A) comply with any instruction received by it from the Collateral Agent in writing that (1) states that an Event of Default has occurred and is continuing and (2) is otherwise in accordance with the terms of this Agreement, without any other or further instructions from such Grantor, and each Grantor agrees that each Issuer shall be fully protected in so complying following receipt of such notice and prior to notice that such Event of Default is no longer continuing, and (B) except as otherwise expressly permitted hereby, pay any dividends, distributions or other payments with respect to any Investment Property or Pledged Equity directly to the Collateral Agent. Unless an Event of Default shall have occurred and be continuing and the Collateral Agent shall have given notice to the relevant Grantor of the Collateral Agent’s intent to exercise its corresponding rights pursuant to this Section 7, each Grantor shall be permitted to receive all cash dividends, payments or other distributions made in respect of any Investment Property and any Pledged Equity, in each case paid in the normal course of business of the relevant Issuer and consistent with past practice, to the extent permitted in the Credit Agreement, and to exercise all voting and other corporate, company and partnership rights with respect to any Investment Property and Pledged Equity to the extent not inconsistent with the terms of this Agreement and the other Loan Documents. (e) Material Contracts. Upon the occurrence of an Event of Default and during the continuation thereof, the Collateral Agent shall be entitled to (but shall not be required to): (i) proceed to perform any and all obligations of the applicable Grantor under any Material Contract constituting Collateral and exercise all rights of such Grantor thereunder as fully as such Grantor itself could, (ii) do all other acts which the Collateral Agent may deem necessary or proper to protect its security interest granted hereunder; provided such acts are not inconsistent with or in violation of the terms of any of the Credit Agreement, the other Loan Documents or applicable Law, and (iii) sell, assign or otherwise transfer any Material Contract constituting Collateral in accordance with the Credit Agreement, the other Loan Documents and applicable Law, subject, however, to the prior approval of any other party to such Material Contract, to the extent such approval is required under such Material Contract. (f) Access. In addition to the rights and remedies hereunder, upon the occurrence of an Event of Default and during the continuance thereof, the Collateral Agent shall have the right to enter and remain upon the various premises of the Grantors without cost or charge to the Collateral Agent, and use the same, together with materials, supplies, books and records of the Grantors, for the purpose of collecting and liquidating the Collateral, or for preparing for sale and conducting the sale of the Collateral, whether by foreclosure, auction or otherwise. In addition, the Collateral Agent may remove Collateral, or any part thereof, from such premises and/or any records with respect thereto, in order to effectively collect or liquidate such Collateral. If the Collateral Agent exercises its right to take possession of the Collateral, each Grantor shall also at its expense perform any and all other steps reasonably requested by the Collateral Agent to preserve and protect the security interest hereby granted in the Collateral, such as placing and maintaining signs indicating

22 the security interest of the Collateral Agent, appointing overseers for the Collateral and maintaining inventory records. (g) Nonexclusive Nature of Remedies. Failure by the Collateral Agent or the other Secured Parties to exercise any right, remedy or option under this Agreement, any other Loan Document, any other document relating to the Obligations, or as provided by Law, or any delay by the Collateral Agent or the other Secured Parties in exercising the same, shall not operate as a waiver of any such right, remedy or option. No waiver hereunder shall be effective unless it is in writing, signed by the party against whom such waiver is sought to be enforced and then only to the extent specifically stated, which in the case of the Collateral Agent or the other Secured Parties shall only be granted as provided herein. To the extent permitted by Law, neither the Collateral Agent, the other Secured Parties, nor any party acting as attorney for the Collateral Agent or the Secured Parties, shall be liable hereunder for any acts or omissions or for any error of judgment or mistake of fact or law other than their gross negligence or willful misconduct hereunder as determined by a final non-appealable judgment of a court of competent jurisdiction. The rights and remedies of the Collateral Agent and the Secured Parties under this Agreement shall be cumulative and not exclusive of any other right or remedy which the Collateral Agent or the Secured Parties may have. (h) Retention of Collateral. In addition to the rights and remedies hereunder, the Collateral Agent may, in compliance with Sections 9-620 and 9-621 of the UCC or otherwise complying with the requirements of applicable Law of the relevant jurisdiction, accept or retain the Collateral in satisfaction of the Obligations. Unless and until the Collateral Agent shall have provided such notices, however, the Collateral Agent shall not be deemed to have retained any Collateral in satisfaction of any Obligations for any reason. (i) Waiver; Deficiency. Each Grantor hereby waives, to the extent permitted by applicable Laws, all rights of redemption, appraisement, valuation, stay, extension or moratorium now or hereafter in force under any applicable Laws in order to prevent or delay the enforcement of this Agreement or the absolute sale of the Collateral or any portion thereof. In the event that the proceeds of any sale, collection or realization are insufficient to pay all amounts to which the Collateral Agent or the Secured Parties are legally entitled, the Grantors shall be jointly and severally liable for the deficiency, together with interest thereon at the Default Rate, together with the costs of collection and the fees, charges and disbursements of counsel. Any surplus remaining after the full payment and satisfaction of the Obligations shall be returned to the Grantors or to whomsoever a court of competent jurisdiction shall determine to be entitled thereto. 8. Rights of the Collateral Agent. (a) Power of Attorney. In addition to other powers of attorney contained herein, each Grantor hereby designates and appoints the Collateral Agent, on behalf of the Secured Parties, and each of its designees or agents, as attorney-in-fact of such Grantor, irrevocably and with power of substitution, with authority to take any or all of the following actions upon the occurrence and during the continuance of an Event of Default:

23 (i) to demand, collect, settle, compromise, adjust, and give discharges and releases; (ii) to commence and prosecute any actions at any court for the purposes of collecting any Collateral and enforcing any other right in respect thereof; (iii) to defend, settle or compromise any action brought and, in connection therewith, give such discharge or release; (iv) to receive, open and dispose of mail addressed to a Grantor and endorse checks, notes, drafts, acceptances, money orders, bills of lading, warehouse receipts or other instruments or documents evidencing payment, shipment or storage of the goods giving rise to the Collateral of such Grantor on behalf of and in the name of such Grantor, or securing, or relating to, such Collateral; (v) to sell, assign, transfer, make any agreement in respect of, or otherwise deal with or exercise rights in respect of, any Collateral or the goods or services which have given rise thereto, as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes; (vi) to adjust and settle claims under any insurance policy relating thereto; (vii) to execute and deliver all assignments, conveyances, statements, financing statements, continuation financing statements, security agreements, affidavits, notices and other agreements, instruments and documents that the Collateral Agent may determine necessary in order to perfect and maintain the security interests and liens granted in this Agreement and in order to fully consummate all of the transactions contemplated herein; (viii) to institute any foreclosure proceedings; (ix) to sign and endorse any drafts, assignments, proxies, stock powers, verifications, notices and other documents relating to the Collateral; (x) to exchange any of the Pledged Equity or other property upon any merger, consolidation, reorganization, recapitalization or other readjustment of the Issuer thereof and, in connection therewith, deposit any of the Pledged Equity with any committee, depository, transfer agent, registrar or other designated agency; (xi) to vote for a shareholder resolution, or to sign an instrument in writing, sanctioning the transfer of any or all of the Pledged Equity into the name of the Collateral Agent or one or more of the Secured Parties or into the name of

24 any transferee to whom the Pledged Equity or any part thereof may be sold pursuant to Section 7 hereof; (xii) to pay or discharge taxes, liens, security interests or other encumbrances levied or placed on or threatened against the Collateral; (xiii) to direct any parties liable for any payment in connection with any of the Collateral to make payment of any and all monies due and to become due thereunder directly to the Collateral Agent or as the Collateral Agent shall direct; (xiv) to receive payment of and receipt for any and all monies, claims, and other amounts due and to become due at any time in respect of or arising out of any Collateral; (xv) in the case of any Intellectual Property, to execute and deliver, and have recorded, any and all agreements, instruments, documents and papers as the Collateral Agent may request to evidence the security interests created hereby in such Intellectual Property and the goodwill and General Intangibles of such Grantor relating thereto or represented thereby; and (xvi) to do and perform all such other acts and things necessary, proper or convenient in connection with the Collateral. This power of attorney is a power coupled with an interest and shall be irrevocable so long as any Lender shall have any Commitment under the Credit Agreement, or any Loan or other Obligation under the Credit Agreement shall remain unpaid or unsatisfied. The Collateral Agent shall be under no duty to exercise or withhold the exercise of any of the rights, powers, privileges and options expressly or implicitly granted to the Collateral Agent in this Agreement, and shall not be liable for any failure to do so or any delay in doing so. The Collateral Agent shall not be liable for any act or omission or for any error of judgment or any mistake of fact or law in its individual capacity or its capacity as attorney-in-fact except acts or omissions resulting from its gross negligence or willful misconduct as determined by a final non-appealable judgment of a court of competent jurisdiction. This power of attorney is conferred on the Collateral Agent solely to protect, preserve and realize upon its security interest in the Collateral and shall not impose any duty upon the Collateral Agent or any other Secured Party to exercise any such powers. (b) Assignment by the Collateral Agent. The Collateral Agent may from time to time assign the Obligations to a successor Collateral Agent appointed in accordance with the Credit Agreement, and such successor shall be entitled to all of the rights and remedies of the Collateral Agent under this Agreement in relation thereto. (c) The Collateral Agent’s Duty of Care. Other than the exercise of reasonable care to assure the safe custody of the Collateral while being held by the Collateral Agent hereunder, the Collateral Agent shall have no duty or liability to preserve rights pertaining thereto, it being understood and agreed that the Grantors shall be responsible for

25 preservation of all rights in the Collateral, and the Collateral Agent shall be relieved of all responsibility for the Collateral upon surrendering it or tendering the surrender of it to the Grantors. The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which the Collateral Agent accords its own property, which shall be no less than the treatment employed by a reasonable and prudent agent in the industry, it being understood that the Collateral Agent shall not have responsibility for taking any necessary steps to preserve rights against any parties with respect to any of the Collateral. In the event of a public or private sale of Collateral pursuant to Section 7 hereof, the Collateral Agent shall have no responsibility for (i) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relating to any Collateral, whether or not the Collateral Agent has or is deemed to have knowledge of such matters, or (ii) taking any steps to clean, repair or otherwise prepare the Collateral for sale. (d) Liability with Respect to Accounts. Anything herein to the contrary notwithstanding, each of the Grantors shall remain liable under each of the Accounts to observe and perform all the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of any agreement giving rise to each such Account.

(ii) The Collateral Agent may release any of the Pledged Equity from this Agreement or may substitute any of the Pledged Equity for other Pledged Equity without altering, varying or diminishing in any way the force, effect, lien, pledge or security interest of this Agreement as to any Pledged Equity not expressly released or substituted, and this Agreement shall continue as a first priority lien on all Pledged Equity not expressly released or substituted.

26 9. Application of Proceeds. After the exercise of remedies provided for in Section 8.02 of the Credit Agreement (or after the Loans have automatically become immediately due and payable), any payments in respect of the Obligations and any proceeds of the Collateral, when received by the Collateral Agent or any other Secured Party in cash or Cash Equivalents, will be applied in reduction of the Obligations in the order set forth in the Credit Agreement. 10. Continuing Agreement. (a) This Agreement shall remain in full force and effect until termination of the Aggregate Commitments and payment in full of all Obligations (other than contingent indemnification obligations), at which time this Agreement shall be automatically terminated (other than obligations under this Agreement which expressly survive such termination) and the Collateral Agent shall, upon the request and at the expense of the Grantors, forthwith release all of its liens and security interests hereunder and shall execute and deliver all UCC termination statements and/or other documents reasonably requested by the Grantors evidencing such termination. (b) This Agreement shall continue to be effective or be automatically reinstated, as the case may be, if at any time payment, in whole or in part, of any of the Obligations is rescinded or must otherwise be restored or returned by the Collateral Agent or any other Secured Party as a preference, fraudulent conveyance or otherwise under any Debtor Relief Law, all as though such payment had not been made; provided that in the event payment of all or any part of the Obligations is rescinded or must be restored or returned, all reasonable costs and expenses (including without limitation any reasonable legal fees and disbursements) incurred by the Collateral Agent or any other Secured Party in defending and enforcing such reinstatement shall be deemed to be included as a part of the Obligations. 11.

It shall not be necessary in making proof of this Agreement to produce or account for more than one such counterpart. Delivery of an executed counterpart of a signature

The terms of Sections 10.14 and 10.15 of the Credit Agreement with respect to governing law, submission to jurisdiction, venue and waiver of jury trial are incorporated herein by reference, mutatis mutandis, and the parties hereto agree to such terms. 17. Severability. If any provision of this Agreement is determined to be illegal, invalid or unenforceable, such provision shall be fully severable and the remaining provisions shall remain in full force and effect and shall be construed without giving effect to the illegal, invalid or unenforceable provisions. 18. Entirety. This Agreement, the other Loan Documents and the other documents relating to the Obligations represent the entire agreement of the parties hereto and thereto, and supersede all prior agreements and understandings, oral or written, if any, including any commitment letters or correspondence relating to the Loan Documents, any other documents relating to the Obligations, or the transactions contemplated herein and therein. 19. Other Security. To the extent that any of the Obligations are now or hereafter secured by property other than the Collateral (including, without limitation, real property and securities owned by a Grantor), or by a guarantee, endorsement or property of any other Person, then the Collateral Agent shall have the right to proceed against such other property, guarantee or endorsement upon the occurrence of any Event of Default and during the continuance thereof, and the Collateral Agent shall have the right to determine which rights, security, liens, security interests or remedies the Collateral Agent shall at any time pursue, relinquish, subordinate, modify or take with respect thereto, without in any way modifying or affecting any of them or the Obligations or any of the rights of the Collateral Agent or the Secured Parties under this Agreement, under any other of the Loan Documents or under any other document relating to the Obligations. 20. Joinder. At any time after the date of this Agreement, one or more additional Persons may become party hereto by executing and delivering to the Collateral Agent a joinder agreement in form acceptable to the Collateral Agent and the Required Lenders. Immediately upon such execution and delivery of such joinder agreement (and without any further action), each such additional Person will become a party to this Agreement as a “Grantor” and have all of the rights and obligations of a Grantor hereunder, and this Agreement and the Schedules hereto shall be deemed amended by such joinder agreement. 21. Consent of Issuers of Pledged Equity. Any Loan Party that is an Issuer hereby acknowledges, consents and agrees to the grant of the security interests in such Pledged Equity

28 by the applicable Grantors pursuant to this Agreement, together with all rights accompanying such security interest as provided by this Agreement and applicable Law, notwithstanding any anti-assignment provisions in any operating agreement, limited partnership agreement or similar organizational or governance documents of such Issuer. 22. Joint and Several Obligations of Grantors. (a) Each of the Grantors is accepting joint and several liability hereunder in consideration of the financial accommodations to be provided by the Lenders under the Credit Agreement, for the mutual benefit, directly and indirectly, of each of the Grantors and in consideration of the undertakings of each of the Grantors to accept joint and several liability for the obligations of each of them. (b) Each of the Grantors jointly and severally hereby irrevocably and unconditionally accepts, not merely as a surety but also as a primary obligor, joint and several liability with the other Grantors with respect to the payment and performance of all of the Obligations, it being the intention of the parties hereto that (i) all the Obligations shall be the joint and several obligations of each of the Grantors without preferences or distinction among them and (ii) a separate action may be brought against each Grantor to enforce this Agreement whether or not the Borrower, any other Grantor or any other person or entity is joined as a party. (c) Notwithstanding any provision to the contrary contained herein, or in any other of the Loan Documents, to the extent the obligations of a Grantor shall be adjudicated to be invalid or unenforceable for any reason (including, without limitation, because of any applicable state or federal law relating to fraudulent conveyances or transfers), then the obligations of such Grantor hereunder shall be limited to the maximum amount that is permissible under applicable law (whether federal or state and including, without limitation, Debtor Relief Laws). 23. Marshaling. The Collateral Agent shall not be required to marshal any present or future collateral security (including but not limited to the Collateral) for, or other assurances of payment of, the Obligations or any of them or to resort to such collateral security or other assurances of payment in any particular order, and all of its rights and remedies hereunder and in respect of such collateral security and other assurances of payment shall be cumulative and in addition to all other rights and remedies, however existing or arising. To the extent that it lawfully may, each Grantor hereby agrees that it will not invoke any law relating to the marshaling of collateral which might cause delay in or impede the enforcement of the Collateral Agent’s rights and remedies under this Agreement or under any other instrument creating or evidencing any of the Obligations or under which any of the Obligations is outstanding or by which any of the Obligations is secured or payment thereof is otherwise assured, and, to the extent that it lawfully may, each Grantor hereby irrevocably waives the benefits of all such laws. 24. Injunctive Relief.

29 (a) Each Grantor recognizes that, in the event such Grantor fails to perform, observe or discharge any of its obligations or liabilities under this Agreement or any other Loan Document, any remedy of law may prove to be inadequate relief to the Collateral Agent and the other Secured Parties. Therefore, each Grantor agrees that the Collateral Agent and the other Secured Parties, at the option of the Collateral Agent and the other Secured Parties, shall be entitled to temporary and permanent injunctive relief in any such case without the necessity of proving actual damages. (b) The Collateral Agent, the other Secured Parties and each Grantor hereby agree that no such Person shall have a remedy of punitive or exemplary damages against any other party to a Loan Document and each such Person hereby waives any right or claim to punitive or exemplary damages that it may now have or may arise in the future in connection with any dispute under this Agreement or any other Loan Document, whether such dispute is resolved through arbitration or judicially. 25. Secured Parties. Each Secured Party that is not a party to the Credit Agreement who obtains the benefit of this Agreement shall be deemed to have acknowledged and accepted the appointment of the Collateral Agent pursuant to the terms of the Credit Agreement, and with respect to the actions and omissions of the Collateral Agent hereunder or otherwise relating hereto that do or may affect such Secured Party, the Collateral Agent and each of its Affiliates shall be entitled to all of the rights, benefits and immunities conferred under Article IX of the Credit Agreement.
