ARTICLE II

AMOUNT AND TERMS OF THE TERM LOAN COMMITMENTS

Section 2.1. General Description of Facilities. Subject to and upon the terms and conditions herein set forth, each Lender severally agrees to make a single Term Loan to the Borrower, in a single drawing, in a principal amount not exceeding such Lender’s Term Loan Commitment on the Closing Date.

Section 2.2. [Reserved].

Section 2.3. Procedure for Borrowing.

The Borrower shall give the Administrative Agent written notice (or telephonic notice promptly confirmed in writing) of the Borrowing substantially in the form of Exhibit 2.3(a) (a “Notice of Term Loan Borrowing”). The Borrower may only submit one Notice of Term Loan Borrowing which must be submitted on or prior to the Closing Date. On the Closing Date, the Term Loans will be funded as a Eurodollar Borrowing with an initial Interest Period of two weeks and an Adjusted LIBO Rate calculated by the Administrative Agent two (2) Business Days prior to the Closing Date. Upon the funding of the Term Loans pursuant to the Notice of Term Loan Borrowing, all unused Term Loan Commitments shall be terminated.

Section 2.4. [Reserved].

Section 2.5. [Reserved].

Section 2.6. Funding of Term Loans. Each Lender will make available the Term Loan to be made by it hereunder on the proposed date thereof by wire transfer in immediately available funds by 11:00 a.m. (New York time) to the Administrative Agent at the Payment Office. The Administrative Agent will make such Term Loans available to the Borrower by promptly crediting the amounts that it receives, in like funds by 1:00 pm (New York time) on the Closing Date, to an account maintained by the Borrower with the Administrative Agent or at the Borrower’s option, by effecting a wire transfer of such amounts to an account designated by the Borrower to the Administrative Agent.

Section 2.7. Interest Elections.

(a) The Borrowing initially shall be of the Type specified in the Notice of Borrowing, and in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in the Notice of Borrowing. Thereafter, the Borrower may elect to convert Term Loans into different Types or to continue such Term Loans, and in the case of Eurodollar Term Loans, may elect Interest Periods therefor, all as provided in this Section 2.7. The Borrower may elect different options with respect to different portions of the Term Loans, in which case each such portion shall be allocated ratably among the Lenders holding such Term Loans, and the Term Loans comprising each such portion shall be considered separate Term Loans.

(b) To make an election pursuant to this Section 2.7, the Borrower shall give the Administrative Agent prior written notice (or telephonic notice promptly confirmed in writing)

of each Term Loan substantially in the form of Exhibit 2.7 attached hereto (a “Notice of Conversion/Continuation”) that is to be converted or continued, as the case may be, (x) prior to 10:00 a.m. (New York time) on the requested date of a conversion into a Base Rate Term Loan and (y) prior to 11:00 a.m. (New York time) three (3) Business Days prior to a continuation of or conversion into a Eurodollar Term Loan. Each such Notice of Conversion/Continuation shall be irrevocable and shall specify:

(i) the Term Loans to which such Notice of Continuation/Conversion applies and if different options are being elected with respect to different portions thereof, the portions thereof that are to be allocated to each resulting Term Loan (in which case the information to be specified pursuant to clauses (iii) and (iv) shall be specified for each resulting Term Loan);

(ii) the effective date of the election made pursuant to such Notice of Continuation/Conversion, which shall be a Business Day;

(iii) whether the resulting Term Loan is to be a Base Rate Term Loan or a Eurodollar Term Loan; provided, that at no time shall the total number of Eurodollar Term Loans outstanding exceed six; and

(iv) if the resulting Term Loan is to be a Eurodollar Term Loan, the Interest Period applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of “Interest Period”. If any such Notice of Continuation/Conversion requests a Eurodollar Term Loan but does not specify an Interest Period, the Borrower shall be deemed to have selected an Interest Period of one month. The principal amount of any resulting Term Loan shall satisfy the minimum borrowing amount for Eurodollar Term Loans and Base Rate Term Loans set forth in Section 2.3.

(c) If, on the expiration of any Interest Period in respect of any Eurodollar Term Loan, the Borrower shall have failed to deliver a Notice of Conversion/ Continuation, then, unless the Term Loan is repaid as provided herein, the Borrower shall be deemed to have elected to convert such Term Loan to a Base Rate Term Loan. The Borrowing may not be converted into, or continued as, a Eurodollar Borrowing if a Default or an Event of Default exists, unless the Administrative Agent and each of the Lenders shall have otherwise consented in writing. No conversion of any Eurodollar Term Loans shall be permitted except on the last day of the Interest Period in respect thereof.

(d) Upon receipt of any Notice of Conversion/Continuation, the Administrative Agent shall promptly notify each Lender of the details thereof and of such Lender’s portion of each resulting Term Loan.

Section 2.8. [Reserved].

Section 2.9. Repayment of Term Loans. The outstanding balance of all Term Loans shall be due and payable (together with accrued and unpaid interest thereon) on the Maturity Date.

Section 2.10. Evidence of Indebtedness. (a) Each Lender shall maintain in accordance with its usual practice appropriate records evidencing the Indebtedness of the Borrower to such Lender resulting from the Term Loan made by such Lender, including the amounts of principal and interest payable thereon and paid to such Lender from time to time under this Agreement. The Administrative Agent shall maintain appropriate records in which shall be recorded (i) the Term Loan Commitment of each Lender, (ii) the amount of each Term Loan made hereunder by each Lender, the Type thereof and the Interest Period applicable thereto, (iii) the date of each continuation thereof pursuant to Section 2.7, (iv) the date of each conversion of all or a portion thereof to another Type pursuant to Section 2.7, (v) the date and amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder in respect of such Term Loans and (vi) both the date and amount of any sum received by the Administrative Agent hereunder from the Borrower in respect of the Term Loans and each Lender’s Pro Rata Share thereof. The entries made in such records shall be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, that the failure or delay of any Lender or the Administrative Agent in maintaining or making entries into any such record or any error therein shall not in any manner affect the obligation of the Borrower to repay the Term Loans (both principal and unpaid accrued interest) of such Lender in accordance with the terms of this Agreement.

(b) At the request of any Lender at any time, the Borrower agrees that it will execute and deliver to such Lender a Term Note payable to the order of such Lender.

Section 2.11. Optional Prepayments. The Borrower shall have the right at any time and from time to time to prepay any Term Loan, in whole or in part, without premium or penalty, by giving written notice (or telephonic notice promptly confirmed in writing) (an “Optional Prepayment Notice”) to the Administrative Agent no later than (i) in the case of prepayment of any Eurodollar Term Loan, 11:00 a.m. (New York time) not less than three (3) Business Days prior to any such prepayment, and (ii) in the case of any prepayment of any Base Rate Term Loan, not less than one (1) Business Day prior to the date of such prepayment. Upon receipt of any Optional Prepayment Notice, the Administrative Agent shall promptly notify each Lender of the contents thereof and of such Lender’s Pro Rata Share of any such prepayment. Each Optional Prepayment Notice shall be irrevocable and shall specify the proposed date of such prepayment and the principal amount of Term Loans to be prepaid; provided that any such Optional Prepayment Notice may state that such Optional Prepayment Notice is conditioned upon the effectiveness of other credit facilities or acquisitions or the receipt of net proceeds from the issuance of Capital Stock of the Borrower, in which case such Optional Prepayment Notice may be revoked by the Borrower giving written notice (or telephonic notice promptly confirmed in writing) to the Administrative Agent on or prior to the date for prepayment specified in such Optional Prepayment Notice if such condition is not satisfied. If an Optional Prepayment Notice is given and has not been revoked by the Borrower in accordance with the proviso to the immediately preceding sentence, the aggregate amount specified in such Optional Prepayment Notice shall be due and payable on the date designated in such Optional Prepayment Notice, together with accrued interest to such date on the amount so prepaid in accordance with Section 2.13(d); provided, that if a Eurodollar Term Loan is prepaid on a date other than the last day of an Interest Period applicable thereto, the Borrower shall also pay all amounts required pursuant to Section 2.19. Each prepayment of a Term Loan shall be applied ratably to the Term Loans

comprising such Borrowing. Any amounts prepaid pursuant to this Section 2.11 may not be reborrowed.

Section 2.12. Mandatory Prepayments;.

(a) Within three (3) Business Days of receipt by the Borrower or any of its Subsidiaries of any proceeds of (x) any sale or disposition by the Borrower or such Subsidiary of any of its assets made after the Closing Date, or (y) any proceeds from any casualty insurance policies or eminent domain, condemnation or similar proceedings in excess of $1,000,000 per occurrence or $5,000,000 in the aggregate, the Borrower shall prepay the Obligations in an amount equal to all such proceeds, net of commissions and other reasonable and customary transaction costs, fees and expenses properly attributable to such transaction and payable by the Borrower in connection therewith (in each case, paid to non-Affiliates); provided, however, that the Borrower shall not be required to prepay the Obligations with respect to (i) proceeds from the sales of assets in the ordinary course of business, (ii) proceeds from the sale or disposition of assets of the Borrower and its Subsidiaries up to an aggregate amount of $5,000,000, and (iii) proceeds that are reinvested in assets then used or usable in the business of the Borrower and its Subsidiaries or used to rebuild or repair assets subject to condemnation or casualty events within 180 days following receipt thereof or are committed to be so reinvested or committed to rebuilding assets pursuant to a binding contract prior to the expiration of such 180-day period and actually so reinvested or so deployed within 270 days following receipt thereof. Any prepayment required by this subsection (a) shall be applied in accordance with subsection (c) of this Section.

(b) If, at any time after the Closing Date, (x) the Borrower or any of its wholly-owned Subsidiaries incurs any Indebtedness for borrowed money or (y) the Borrower issues any Capital Stock, then no later than the third (3rd) Business Day following the date of receipt of the proceeds thereof, the Borrower shall prepay the Obligations in an amount equal to all such proceeds, net of underwriting discounts and commissions and other reasonable and customary transaction costs, fees and expenses properly attributable to such transaction and payable by the Borrower in connection therewith (in each case, paid to non-Affiliates); provided, however, that the Borrower shall not be required to prepay the Obligations with respect to (i) proceeds of Indebtedness permitted under Sections 7.1(a), (c), (d), (f) or (g), (ii) proceeds of Indebtedness incurred by the Borrower under the Revolving and Term Loan Credit Facility, (iii) proceeds of Indebtedness that extends, renews, refinances, or replaces any Indebtedness of the Borrower existing as of the Closing Date (other than the Term Loans); provided that the principal amount of such new Indebtedness is equal to or less than the outstanding principal amount of such existing Indebtedness immediately prior to giving effect to such extension, renewal or replacement plus the amount of fees, expenses, premiums and accrued interest paid in connection with such refinancing and does not have an earlier maturity or shorter weighted average life than such existing Indebtedness), (iv) proceeds of loans or advances made to the Borrower by any Subsidiary, (v) proceeds of Indebtedness incurred by the Borrower that, when aggregated with the outstanding principal amount of Indebtedness incurred by the Subsidiaries of the Borrower under Section 7.1(e), does not exceed $35,000,000 at any one time outstanding, (vi) proceeds of Capital Stock issued by the Borrower to members of management, directors, officers and employees pursuant to employment agreements, compensation or bonus plans, or employee stock or option plans of the Borrower, or (vii) proceeds of Capital Stock issued by the Borrower

pursuant to any dividend reinvestment plan of the Borrower. Any prepayment required by this subsection (b) shall be applied in accordance with subsection (c) of this Section.

(c) Any prepayments made by the Borrower pursuant to subsection (a) or (b) above shall be applied as follows: first, to the Administrative Agent’s fees and reimbursable expenses then due and payable pursuant to any of the Loan Documents; second, to all reimbursable expenses of the Lenders, pro rata based on their respective pro rata shares of such fees and expenses; third, to interest and fees then due and payable hereunder, pro rata to the Lenders based on their respective pro rata shares of such interest and fees; fourth, to the principal balance of the Term Loans, until the same shall have been paid in full, pro rata to the Lenders based on their Pro Rata Shares of the Term Loans and fifth, to the Borrower for its own account; provided, that the Term Loan Commitments of each Lender shall be reduced, pro rata based on their Pro Rata Shares of the Term Loan Commitments on a dollar-for-dollar basis in an amount equal to the amount of proceeds delivered to the Borrower pursuant to this Section.

Section 2.13. Interest on Term Loans.

(a) The Borrower shall pay interest on each Base Rate Term Loan at the Base Rate in effect from time to time and on each Eurodollar Term Loan at the Adjusted LIBO Rate for the applicable Interest Period in effect for such Term Loan, plus, in each case, the Applicable Margin in effect from time to time.

(b) While an Event of Default exists or after acceleration, at the option of the Required Lenders, the Borrower shall pay interest (“Default Interest”) with respect to all Eurodollar Term Loans at the rate otherwise applicable for the then-current Interest Period plus an additional 2% per annum until the last day of such Interest Period, and thereafter, and with respect to all Base Rate Term Loans and all other Obligations hereunder (other than Term Loans), at the rate in effect for Base Rate Term Loans, plus an additional 2% per annum.

(c) Interest on the principal amount of all Term Loans shall accrue from and including the date such Term Loans are made to but excluding the date of any repayment thereof. Interest on all outstanding Base Rate Term Loans shall be payable quarterly in arrears on the last day of each March, June, September and December and on the Maturity Date. Interest on all outstanding Eurodollar Term Loans shall be payable on the last day of each Interest Period applicable thereto, and, in the case of any Eurodollar Term Loans having an Interest Period in excess of three months or 90 days, respectively, on each day which occurs every three months or 90 days, as the case may be, after the initial date of such Interest Period, and on the Maturity Date. Interest on any Term Loan which is converted into a Term Loan of another Type or which is repaid or prepaid shall be payable on the date of such conversion or on the date of any such repayment or prepayment (on the amount repaid or prepaid) thereof. All Default Interest shall be payable on demand.

(d) The Administrative Agent shall determine each interest rate applicable to the Term Loans hereunder and shall promptly notify the Borrower and the Lenders of such rate in writing (or by telephone, promptly confirmed in writing). Any such determination shall be conclusive and binding for all purposes, absent manifest error.

Section 2.14. Fees.

(a) The Borrower shall pay to the Administrative Agent for its own account fees in the amounts and at the times previously agreed upon in writing by the Borrower and the Administrative Agent or the Sole Lead Arranger, including for the avoidance of doubt, fees described in the Fee Letter.

(b) The Borrower agrees to pay to the Administrative Agent for the ratable benefit of each Lender a duration fee: (i) on the date falling 90 days after the Closing Date, in an amount equal to 0.25% times the aggregate principal amount of Term Loans then outstanding; (ii) on the date falling 180 days after the Closing Date, in an amount equal to 0.50% times the aggregate principal amount of the aggregate principal amount of the Term Loans then outstanding; and (iii) on the date falling 270 days after the Closing Date (together with the dates referenced in clauses (i) and (ii) above, each a “Determination Date”), in an amount equal to 0.75% times the aggregate principal amount of the Term Loans then outstanding; provided, that, no duration fee shall be payable on any Determination Date if as of such Determination Date either (x) the Leverage Ratio is less than 3.75:1.00; or (y) the aggregate principal balance of Term Loans, together with accrued and unpaid fees (other than any otherwise applicable duration fee), interest and other amounts is less than $100,000,000. The duration fee shall be payable on the first Business Day following each Determination Date.

(c) The Borrower shall pay to the Administrative Agent, for the ratable benefit of each Lender, the upfront fee previously agreed upon by the Borrower and the Administrative Agent as detailed in the Fee Letter, which shall be due and payable on the Closing Date.

Section 2.15. Computation of Interest and Fees.

All computations of interest based on the Base Rate shall be made by the Administrative Agent on the basis of a year of 365/366 days, as the case may be, and all computations of interest based on LIBOR or the Federal Funds Rate and of fees hereunder shall be made on the basis of a year of 360 days for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable (to the extent computed on the basis of days elapsed). Each determination by the Administrative Agent of an interest amount or fee hereunder shall be made in good faith and, except for manifest error, shall be final, conclusive and binding for all purposes.

Section 2.16. Inability to Determine Interest Rates. If prior to the commencement of any Interest Period for any Eurodollar Term Loan,

(i) the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances affecting the relevant interbank market, adequate means do not exist for ascertaining LIBOR for such Interest Period, or

(ii) the Administrative Agent shall have received notice from the Required Lenders that the Adjusted LIBO Rate does not adequately and fairly reflect the cost to such Lenders (or Lender, as the case may be) of making, funding or maintaining their (or its, as the case may be) Eurodollar Term Loans for such Interest Period,

the Administrative Agent shall give written notice (or telephonic notice, promptly confirmed in writing) to the Borrower and to the Lenders as soon as practicable thereafter. Until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) the obligations of the Lenders to continue or convert outstanding Term Loans as or into Eurodollar Term Loans shall be suspended and (ii) all such affected Term Loans shall be converted into Base Rate Term Loans on the last day of the then current Interest Period applicable thereto unless the Borrower prepays such Term Loans in accordance with this Agreement.

Section 2.17. Illegality. If, after the date of this Agreement, any Change in Law shall make it unlawful or impossible for any Lender to make, maintain or fund any Eurodollar Term Loan and such Lender shall so promptly notify the Administrative Agent, the Administrative Agent shall promptly give notice thereof to the Borrower and the other Lenders, whereupon until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such suspension no longer exist, the obligation of such Lender to continue or convert outstanding Term Loans as or into Eurodollar Term Loans, shall be suspended. If the affected Eurodollar Term Loan is then outstanding, such Term Loan shall be converted to a Base Rate Term Loan either (i) on the last day of the then current Interest Period applicable to such Eurodollar Term Loan if such Lender may lawfully continue to maintain such Term Loan to such date or (ii) immediately if such Lender shall determine that it may not lawfully continue to maintain such Eurodollar Term Loan to such date. Notwithstanding the foregoing, the affected Lender shall, prior to giving such notice to the Administrative Agent, designate a different Applicable Lending Office if such designation would avoid the need for giving such notice and if such designation would not otherwise be disadvantageous to such Lender in the good faith exercise of its discretion.

Section 2.18. Increased Costs.

(a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement that is not otherwise included in the determination of the Adjusted LIBO Rate hereunder against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate); or

(ii) impose on any Lender or the eurodollar interbank market any other condition affecting this Agreement or any Eurodollar Term Loans made by such Lender;

and the result of either of the foregoing is to increase the cost to such Lender of making, converting into, continuing or maintaining a Eurodollar Term Loan or to increase the cost to such Lender or to reduce the amount received or receivable by such Lender hereunder (whether of principal, interest or any other amount), then the Borrower shall promptly pay, upon written notice from and demand by such Lender on the Borrower (with a copy of such notice and demand to the Administrative Agent), to the Administrative Agent for the account of such Lender, within five Business Days after the date of such notice and demand, additional amount or amounts sufficient to compensate such Lender for such additional costs incurred or reduction

suffered; provided, that amounts paid under this Section 2.18(a) shall be without duplication of amounts paid under Section 2.20 and shall not include Excluded Taxes.

(b) If any Lender shall have determined that on or after the date of this Agreement any Change in Law regarding capital 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 parent corporation) as a consequence of its obligations hereunder to a level below that which such Lender or such Lender’s parent corporation could have achieved but for such Change in Law (taking into consideration such Lender’s policies or the policies of such Lender’s parent corporation with respect to capital adequacy) then, from time to time, within five (5) Business Days after receipt by the Borrower of written demand by such Lender (with a copy thereof to the Administrative Agent), the Borrower shall pay to such Lender such additional amounts as will compensate such Lender or such Lender’s parent corporation for any such reduction suffered.

(c) A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or such Lender’s parent corporation, as the case may be, specified in paragraph (a) or (b) of this Section 2.18 shall be delivered to the Borrower (with a copy to the Administrative Agent) and shall be conclusive, absent manifest error. The Borrower shall pay any such Lender such amount or amounts within 10 days after receipt thereof.

(d) Except as provided in Section 2.18(e), failure or delay on the part of any Lender to demand compensation pursuant to this Section 2.18 shall not constitute a waiver of such Lender’s right to demand such compensation.

(e) Notwithstanding anything to the contrary in this Section 2.18, the Borrower shall not be required to compensate a Lender pursuant to this Section 2.18 for any amounts incurred prior to the date that such Lender notifies the Borrower of such Lender’s intention to claim compensation therefor; provided that, if the circumstances giving rise to such claim have a retroactive effect, then such six-month period shall be extended to include the period of such retroactive effect.

Section 2.19. Funding Indemnity. In the event of (a) the payment of any principal of a Eurodollar Term Loan other than on the last day of the Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion or continuation of a Eurodollar Term Loan other than on the last day of the Interest Period applicable thereto, or (c) the failure by the Borrower to borrow, prepay, convert or continue any Eurodollar Term Loan on the date specified in any applicable notice (regardless of whether such notice is withdrawn or revoked), then, in any such event, the Borrower shall compensate each Lender, within five (5) Business Days after written demand from such Lender, for any loss, cost or expense attributable to such event. In the case of a Eurodollar Term Loan, such loss, cost or expense shall be deemed to include an amount determined by such Lender to be the excess, if any, of (A) the amount of interest that would have accrued on the principal amount of such Eurodollar Term Loan if such event had not occurred at the Adjusted LIBO Rate applicable to such Eurodollar Term Loan for the period from the date of such event to the last day of the then current Interest Period therefor (or in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Eurodollar Term Loan) over (B) the amount of interest that would accrue on the principal amount of such Eurodollar Term Loan for the same period if the Adjusted LIBO

Rate were set on the date such Eurodollar Term Loan was prepaid or converted or the date on which the Borrower failed to borrow, convert or continue such Eurodollar Term Loan. A certificate as to any additional amount payable under this Section 2.19 submitted to the Borrower by any Lender (with a copy to the Administrative Agent) shall be conclusive, absent manifest error.

Section 2.20. Taxes.

(a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided, that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.20 for Indemnified Taxes or Other Taxes) the Administrative Agent and any Lenders, as the case may be, shall receive an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) The Borrower shall indemnify the Administrative Agent and each Lender within five (5) Business Days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such Lender, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 2.20) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other 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, or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, 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 the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the Code or any treaty to which the United States is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate. Without limiting the generality of the foregoing, each Foreign Lender agrees that it will deliver

to the Administrative Agent and the Borrower (or in the case of a Participant, to the Lender from which the related participation shall have been purchased), as appropriate, two (2) duly completed copies of (i) Internal Revenue Service Form W-8 ECI, or any successor form thereto, certifying that the payments received from the Borrower hereunder are effectively connected with such Foreign Lender’s conduct of a trade or business in the United States; or (ii) Internal Revenue Service Form W-8 BEN, or any successor form thereto, certifying that such Foreign Lender is entitled to benefits under an income tax treaty to which the United States is a party which reduces the rate of withholding tax on payments of interest; or (iii) Internal Revenue Service Form W-8 BEN, or any successor form prescribed by the Internal Revenue Service, together with a certificate (A) establishing that the payment to the Foreign Lender qualifies as “portfolio interest” exempt from U.S. withholding tax under Code section 871(h) or 881(c), and (B) stating that (1) the Foreign Lender is not a bank for purposes of Code section 881(c)(3)(A), or the obligation of the Borrower hereunder is not, with respect to such Foreign Lender, a loan agreement entered into in the ordinary course of its trade or business, within the meaning of that section; (2) the Foreign Lender is not a 10% shareholder of the Borrower within the meaning of Code section 871(h)(3) or 881(c)(3)(B); and (3) the Foreign Lender is not a controlled foreign corporation that is related to the Borrower within the meaning of Code section 881(c)(3)(C); or (iv) such other Internal Revenue Service forms as may be applicable to the Foreign Lender, including Forms W-8 IMY or W-8 EXP. Each such Foreign Lender shall deliver to the Borrower and the Administrative Agent such forms on or before the date that it becomes a party to this Agreement (or in the case of a Participant, on or before the date such Participant purchases the related participation). In addition, each such Foreign Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Foreign Lender. Each such Foreign Lender shall promptly notify the Borrower and the Administrative Agent at any time that it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower (or any other form of certification adopted by the Internal Revenue Service for such purpose).

(f) For any period with respect to which a Foreign Lender has failed to provide the Borrower with the appropriate form, certificate or other document described in Section 2.20(e) (other than if such failure is due to a Change in Law, occurring subsequent to the date on which a form, certificate or other document originally was required to be provided, or if such form, certificate or other document otherwise is not required under subsection (e) above), such Foreign Lender shall not be entitled to the additional payment or indemnification under Section 2.20(a) or (c) with respect to Taxes imposed by the United States by reason of such failure; provided, however, that should a Lender become subject to Taxes because of its failure to deliver a form, certificate or other document required hereunder, the Borrower shall take such steps as the Foreign Lender shall reasonably request to assist the Foreign Lender to recover such Taxes.

(g) If the Administrative Agent or any Lender determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid amounts pursuant to this Section 2.20, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.20 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant governmental authority with respect to such refund); provided, that the Borrower, upon

the request of the Administrative Agent or such Lender, 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 Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such governmental authority. This paragraph shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person.

Section 2.21. Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees, or of amounts payable under Sections 2.18, 2.19 or 2.20, or otherwise) prior to 12:00 noon (New York time) on the date when due, in immediately available funds, free and clear of any defenses, rights of set-off or counterclaims. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at the Payment Office except that payments pursuant to Sections 2.18, 2.19 and 2.20 and 10.3 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be made payable for the period of such extension. All payments hereunder shall be made in Dollars.

(b) 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, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties.

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Term Loans that would result in such Lender receiving payment of a greater proportion of the aggregate amount of its Term Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Term Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Term Loans; provided, that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Term Loans to any assignee or participant,

other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph 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 set-off 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.

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on 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, distribute to the Lenders the amount or amounts 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 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 greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Sections 2.6(a), 2.21(d), or 10.3(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

Section 2.22. [Reserved].

Section 2.23. Mitigation of Obligations. If any Lender requests compensation under Section 2.18, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.20, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Term Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the sole judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable under Section 2.18 or Section 2.20, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all costs and expenses incurred by any Lender in connection with such designation or assignment.

Section 2.24. Replacement of Lenders. If any Lender requests compensation under Section 2.18, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority of the account of any Lender pursuant to Section 2.20, or if any Lender defaults in its obligation to fund Term Loans hereunder, 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 set forth in Section 10.4(b)) all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another

Lender); provided, that (i) the Borrower shall have received the prior written consent of the Administrative Agent with respect to the proposed assignee, which consent shall not be unreasonably withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal amount of all Term Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (in the case of such outstanding principal and accrued interest) and from the Borrower (in the case of all other amounts) and (iii) in the case of a claim for compensation under Section 2.18 or payments required to be made pursuant to Section 2.20, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and 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.

(b) Since December 31, 2010, there have been no changes with respect to the Borrower, its Subsidiaries, Northern Border, GLGT, and, to the Borrower’s knowledge, Bison and GTN LLC which have had or could reasonably be expected to have, singly or in the aggregate, a Material Adverse Effect.

Section 4.5. Litigation and Environmental Matters.

(a) No litigation, investigation or proceeding of or before any arbitrators or Governmental Authorities is pending against or, to the knowledge of the Borrower, threatened against the Borrower or any of its Subsidiaries (i) as to which there is a reasonable likelihood of an adverse determination that could reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect or (ii) which in any manner draws into question the validity or enforceability of this Agreement or any other Loan Document.

(b) Except for the matters set forth on Schedule 4.5 and except as could not reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect, neither the Borrower nor any of its Subsidiaries (i) has failed to comply with any Environmental Law or to obtain, maintain or comply with any permit, license or other approval

Neither the Borrower nor any of its Subsidiaries is (a) an “investment company” or is “controlled” by an “investment company”, as such terms are defined in, or subject to regulation under, the Investment Company Act of 1940, as amended, or (b) otherwise subject to any other regulatory scheme limiting its ability to incur debt or requiring any approval or consent from or registration or filing with, any Governmental Authority in connection therewith, except those as have been obtained or made and are in full force and effect.

Section 4.8. Taxes. The Borrower and its Subsidiaries and each other Person for whose taxes the Borrower or any Subsidiary is liable have timely filed or caused to be filed all Federal income tax returns and all other material tax returns that are required to be filed by them, and have paid all taxes shown to be due and payable on such returns or on any assessments made against it or its property and all other taxes, fees or other charges imposed on it or any of its property by any Governmental Authority, except where the same are currently being contested in good faith by appropriate proceedings and for which the Borrower or such Subsidiary, as the case may be, has set aside on its books adequate reserves in accordance with GAAP. The charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of such taxes are adequate, and no tax liabilities that could be materially in excess of the amount so provided are anticipated.

Section 4.9. Margin Regulations. None of the proceeds of any of the Term Loans will be used, directly or indirectly, for “purchasing” or “carrying” any “margin stock” with the respective meanings of each of such terms under Regulation U of the Board of Governors of the Federal Reserve System as now and from time to time hereafter in effect or for any purpose that violates the provisions of the Regulation U. Neither the Borrower nor its Subsidiaries is engaged principally, or as one of its important activities, in the business of extending credit for the purpose of purchasing or carrying “margin stock.”

Section 4.10. ERISA.

reflecting such amounts, exceed the fair market value of the assets of all such underfunded Plans, where the liability, if any, in (a) or (b) above could reasonably be expected to result in a Material Adverse Effect.

(a) Each of the Borrower and its Subsidiaries has good title to, or valid leasehold interests in, all of its real and personal property material to the operation of its business, including all such properties reflected in the most recent audited consolidated balance sheet of the Borrower referred to in Section 4.4 or purported to have been acquired by the Borrower or any Subsidiary after said date (except as sold or otherwise disposed of in the ordinary course of business), in each case free and clear of Liens prohibited by this Agreement. All leases that individually or in the aggregate are material to the business or operations of the Borrower and its Subsidiaries are valid and subsisting and are in full force.

(b) Except as could not reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect, each of the Borrower and its Subsidiaries owns, or is licensed, or otherwise has the right, to use, all patents, trademarks, service marks, trade names, copyrights and other intellectual property material to its business, and the use thereof by the Borrower and its Subsidiaries does not infringe in any material respect on the rights of any other Person.

(c) The properties of the Borrower and its Subsidiaries are insured with financially sound and reputable insurance companies, in such amounts with such deductibles and covering such risks of loss or damage of the kinds customarily carried by companies in the same or similar businesses operating in the same or similar locations, which may include self-insurance, if determined by the Borrower to be reasonably prudent and consistent with business practices as in effect on the date hereof.

Section 4.12. Disclosure. The Borrower has disclosed to the Lenders all agreements, instruments, and corporate or other restrictions to which the Borrower or any of its Subsidiaries is subject, and all other matters known to any of them, that, individually or in the aggregate, could reasonably be expected to result in a Material Adverse Effect. None of the reports (including without limitation all reports that the Borrower is required to file with the Securities and Exchange Commission), financial statements, certificates or other information furnished by or on behalf of the Borrower to the Administrative Agent or any Lender in connection with the negotiation or syndication of this Agreement or any other Loan Document or delivered hereunder or thereunder (as modified or supplemented by any other information so furnished) contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, taken as a whole, in light of the circumstances under which they were made, not materially misleading;

All payments due from the Borrower or any of its Subsidiaries pursuant to the provisions of any collective bargaining agreement have been paid or accrued as a liability on the books of the Borrower or any such Subsidiary, except where the failure to do so could not reasonably be expected to have a Material Adverse Effect.

Section 4.14. Subsidiaries. Schedule 4.14 attaches a true and complete organizational chart of the Borrower and all of its Subsidiaries (including the ownership of Northern Border, Tuscarora, GLGT, Bison and GTN LLC) after giving effect to the Acquisition, which the Borrower shall update upon notice to the Administrative Agent promptly following the completion of any material Permitted Acquisition and promptly following the incorporation, organization or formation of any material Subsidiary.

Section 4.15. Solvency. After giving effect to the execution and delivery of the Loan Documents, the making of the Term Loans under this Agreement, the Borrower and the Borrower together with its Subsidiaries taken as a whole will be Solvent.

ARTICLE IX

THE ADMINISTRATIVE AGENT

Section 9.1. Appointment of the Administrative Agent.

Each Lender irrevocably appoints SunTrust Bank as the Administrative Agent and authorizes it to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent under this Agreement and the other Loan Documents, together with all such actions and powers that are reasonably incidental thereto. The Administrative Agent may perform any of its duties hereunder or under the other Loan Documents by or through any one or more sub-agents or attorneys-in-fact appointed by the Administrative Agent. The Administrative Agent and any such sub-agent or attorney-in-fact may perform any and all of its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions set forth in this Article shall apply to any such sub-agent or attorney-in-fact and the Related Parties of the Administrative Agent, any such sub-agent and any such attorney-in-fact and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as the Administrative Agent.

Section 9.2. Nature of Duties of the Administrative Agent. The Administrative Agent shall not have any duties or obligations except those expressly set forth in this Agreement and the other Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or an Event of Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except those discretionary rights and powers expressly contemplated by the Loan Documents that the Administrative Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 10.2), and (c) except as expressly set forth in the Loan Documents, the Administrative Agent shall not 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 Subsidiaries that is communicated to or obtained by the Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it, its sub-agents or attorneys-in-fact with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 10.2) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents or attorneys-in-fact selected by it with reasonable care. The Administrative Agent shall not be deemed to have knowledge of any Default or Event of Default unless and until written notice thereof (which notice shall include an express reference to such event being a “Default” or “Event of Default” hereunder) is given to the Administrative Agent by the Borrower or any Lender, and 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 any 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 and conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other

agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article III or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. The Administrative Agent may consult with legal counsel (including counsel for the Borrower) concerning all matters pertaining to such duties.

Section 9.3. Lack of Reliance on the Administrative Agent. Each of the Lenders acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender 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 of the Lenders also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, continue to make its own decisions in taking or not taking of any action under or based on this Agreement, any related agreement or any document furnished hereunder or thereunder.

Section 9.4. Certain Rights of the Administrative Agent. If the Administrative Agent shall request instructions from the Required Lenders with respect to any action or actions (including the failure to act) in connection with this Agreement, the Administrative Agent shall be entitled to refrain from such act or taking such act, unless and until it shall have received instructions from such Lenders; and the Administrative Agent shall not incur liability to any Person by reason of so refraining. Without limiting the foregoing, no Lender shall have any right of action whatsoever against the Administrative Agent as a result of the Administrative Agent acting or refraining from acting hereunder in accordance with the instructions of the Required Lenders where required by the terms of this Agreement.

Section 9.5. 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, posting or other distribution) believed by it to be genuine and to have been signed, sent or made by the proper Person. The Administrative Agent may also rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or not taken by it in accordance with the advice of such counsel, accountants or experts.

Section 9.6. The Administrative Agent in its Individual Capacity. The bank serving as the Administrative Agent shall have the same rights and powers under this Agreement and any other Loan Document in its capacity as a Lender as any other Lender and may exercise or refrain from exercising the same as though it were not the Administrative Agent; and the terms “Lenders”, “Required Lenders”, “holders of Notes”, or any similar terms shall, unless the context clearly otherwise indicates, include the Administrative Agent in its individual capacity. The bank acting as the Administrative Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower or any Subsidiary or Affiliate of the Borrower as if it were not the Administrative Agent hereunder.

Section 9.7. Successor Administrative Agent.

(a) The Administrative Agent may resign at any time by giving notice thereof to the Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Administrative Agent, subject to the approval by the Borrower provided that no Default or Event of Default shall exist at such time. If no successor Administrative Agent shall have been so appointed, and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which shall be a commercial bank organized under the laws of the United States of America or any state thereof or a bank which maintains an office in the United States, having a combined capital and surplus of at least $500,000,000.

(b) Upon the acceptance of its appointment as the Administrative Agent hereunder by a successor, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. If within 45 days after written notice is given of the retiring Administrative Agent’s resignation under this Section 9.7 no successor Administrative Agent shall have been appointed and shall have accepted such appointment, then on such 45th day (i) the retiring Administrative Agent’s resignation shall become effective, (ii) the retiring Administrative Agent shall thereupon be discharged from its duties and obligations under the Loan Documents and (iii) the Required Lenders shall thereafter perform all duties of the retiring Administrative Agent under the Loan Documents until such time as the Required Lenders appoint a successor Administrative Agent as provided above. After any retiring Administrative Agent’s resignation hereunder, the provisions of this Article shall continue in effect for the benefit of such retiring Administrative Agent and its representatives and agents in respect of any actions taken or not taken by any of them while it was serving as the Administrative Agent.

Section 9.8. Authorization to Execute other Loan Documents. Each Lender hereby authorizes the Administrative Agent to execute on behalf of all Lenders all Loan Documents other than this Agreement.

Any party hereto may change its address or telecopy number for notices and other communications hereunder by notice to the other parties hereto. All such notices and other communications shall, when transmitted by overnight delivery, or faxed, be effective when delivered for overnight (next-day) delivery, or transmitted in legible form by facsimile machine, respectively, or if mailed, upon the third Business Day after the date deposited into the mail or if delivered, upon delivery; provided, that the Notice of Term Loan Borrowing, any Notices of Conversion/Continuation, and any notices provided under Section 5.2 or 5.3 delivered to the Administrative Agent shall not be effective until actually received by the Administrative Agent at its address specified in this Section 10.1.

(ii) Any agreement of the Administrative Agent and the Lenders herein to receive certain notices by telephone or facsimile is solely for the convenience and at the request of the Borrower. The Administrative Agent and the Lenders shall be entitled to rely on the authority of any Person believed by it to be a Person authorized by the Borrower to give such notice and the Administrative Agent and Lenders shall not have any liability to the Borrower or other Person on account of any action taken or not taken by the Administrative Agent or the Lenders in reliance upon such telephonic or facsimile notice. The obligation of the Borrower to repay the Term Loans and all other Obligations hereunder shall not be affected in any way or to any extent by any failure of the Administrative Agent and the Lenders to receive written confirmation of any telephonic or facsimile notice or the receipt by the Administrative Agent and the Lenders of a confirmation which is at variance with the terms understood by the Administrative Agent and the Lenders to be contained in any such telephonic or facsimile notice.

(b) Electronic Communications.

(i) Notices and other communications to the Lenders hereunder may be delivered or furnished by electronic communication (including e-mail and Internet or intranet websites) pursuant to procedures approved by the Administrative Agent, provided that the foregoing shall not apply to notices to any Lender pursuant to Article II unless such Lender and the Administrative Agent have agreed to receive notices under such Section by electronic communication and have agreed to the procedures governing such communications. The Administrative Agent or the Borrower may, 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.

(ii) Unless the Administrative Agent otherwise prescribes, (A) 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); provided that if such notice or other communication is not sent during the normal business hours of the recipient, such notice or communication shall be deemed to have been sent at the opening of business on the next business day for the recipient, and (B) 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.

Section 10.2. Waiver; Amendments.

(a) No failure or delay by the Administrative Agent, or any Lender in exercising any right or power hereunder or any other Loan Document, and no course of dealing between the Borrower and the Administrative Agent or any Lender, shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power or any abandonment or discontinuance of steps to enforce such right or power, preclude any other or further exercise

thereof or the exercise of any other right or power hereunder or thereunder. The rights and remedies of the Administrative Agent and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies provided by law. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section 10.2, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Term Loan shall not be construed as a waiver of any Default or Event of Default, regardless of whether the Administrative Agent, any Lender may have had notice or knowledge of such Default or Event of Default at the time.

(b) No amendment or waiver of any provision of this Agreement or the other Loan Documents, nor consent to any departure by the Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by the Borrower and the Required Lenders or the Borrower and the Administrative Agent with the consent of the Required Lenders and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, that no amendment or waiver shall: (i) increase the Term Loan Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Term Loan or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the date fixed for any payment of any principal of, or interest on, any Term Loan or interest thereon or any fees hereunder or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date for the termination or reduction of any Term Loan Commitment, without the written consent of each Lender affected thereby, provided, however, that this clause (iii) shall not apply to the postponement of the date fixed for, or the waiver of any requirement by the Borrower to make, any optional prepayment Section 2.11 or any mandatory prepayment under Section 2.12 (it being understood that such postponement or waiver shall be effective with the written consent of the Required Lenders), (iv) change Section 2.21(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, or (v) change any of the provisions of this Section 10.2 or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders which are required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the consent of each Lender; provided further, that no such agreement shall amend, modify or otherwise affect the rights, duties or obligations of the Administrative Agent without the prior written consent of the Administrative Agent. Notwithstanding anything contained herein to the contrary, this Agreement may be amended and restated without the consent of any Lender (but with the consent of the Borrower and the Administrative Agent) if, upon giving effect to such amendment and restatement, such Lender shall no longer be a party to this Agreement (as so amended and restated), the Term Loan Commitments of such Lender shall have terminated (but such Lender shall continue to be entitled to the benefits of Sections 2.18, 2.19, 2.20 and 10.3), such Lender shall have no other commitment or other obligation hereunder and shall have been paid in full all principal, interest and other amounts owing to it or accrued for its account under this Agreement.

(c) Notwithstanding anything set forth herein, the Borrower, the Administrative Agent and the Lenders agree that so long as the Revolving and Term Loan Credit Facility is in effect, if any provision contained therein is amended then the corresponding provision in this

Agreement shall be deemed amended to the same extent amended in the Revolving and Term Loan Credit Facility, effective hereunder when such amendment becomes effective thereunder, automatically and without any action necessary by the Borrower, the Administrative Agent or any Lender, provided that this Section 10.2(c) shall not apply to (i) the definition of “Applicable Margin”, “Applicable Margin Step-up”, “Fee Letter”, “Term Loan Commitment”, “Term Loan” and “Term Note” and (ii) any provision contained in Article II (other than Sections 2.16, 2.17, 2.18, 2.19 and 2.20), Article III or Section 8.1(f) of this Agreement; provided further that notwithstanding this Section 10.2(c), (A) the maximum Leverage Ratio permitted by Section 6.1 as of the end of the Fiscal Quarters ending June 30, 2011, September 30, 2011 and December 31, 2011 shall not exceed 5.50:1.00, (B) the maximum Leverage Ratio permitted by Section 6.1 as of the end of any Fiscal Quarter ending on or after March 31, 2012 shall not exceed 5.00:1.00 and (C) the minimum Interest Coverage Ratio required by Section 6.2 as of the end of any Fiscal Quarter shall not be less than 2.50:1.00 (unless such amendment allows for the removal of the Interest Coverage Ratio if the Borrower obtains a rating of at least Baa3/BBB- from either S&P or Xxxxx’x (as applicable)). This Section 10.2(c) shall not require any amendments that would have the effect of changing the character of the Term Loans hereunder into revolving loans. The Borrower agrees to provide the Administrative Agent and each Lender with a copy of such amendment. The Administrative Agent and each Lender agrees to execute and deliver promptly, and in any event within 30 days (or such longer period as the Administrative Agent may agree in its sole discretion), a document in form and substance satisfactory to the Administrative Agent to reflect any such amendment pursuant to this subsection (c), provided, that the execution and delivery of such document shall not be a condition to the effectiveness of such amendment.

Section 10.3. Expenses; Indemnification.

(a) The Borrower shall pay (i) all reasonable, out-of-pocket costs and expenses of the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent and its Affiliates, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of the Loan Documents and any amendments, modifications or waivers thereof (whether or not the transactions contemplated in this Agreement or any other Loan Document shall be consummated), and (ii) all out-of-pocket costs and expenses incurred by the Administrative Agent or any Lender in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section 10.3, or in connection with the Term Loans made hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Term Loans; provided that the Borrower shall only be responsible for reimbursing the legal fees and expenses of one outside counsel for the Administrative Agent and the Lenders.

(b) The Borrower shall indemnify the Administrative Agent (and any sub-agent thereof), each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses (including the fees, charges and disbursements of any counsel for any Indemnitee), and shall indemnify and hold harmless each Indemnitee from all fees and time charges and disbursements for attorneys who may be employees of any Indemnitee, incurred by any Indemnitee or asserted against any Indemnitee by

any third party or by the Borrower arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder or the consummation of the transactions contemplated hereby or thereby, (ii) any Term Loan or the use or proposed use of the proceeds therefrom, (iii) any actual or alleged presence or Release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by the Borrower, and regardless of whether any Indemnitee is a party thereto, provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or (y) result from a claim brought by the Borrower against an Indemnitee for breach in bad faith of such Indemnitee’s obligations hereunder or under any other Loan Document, if the Borrower has obtained a final judgment in its favor on such claim as determined by a court of competent jurisdiction.

(c) To the extent that the Borrower fails to pay any amount required to be paid to the Administrative Agent under clauses (a) or (b) hereof, each Lender severally agrees to pay to the Administrative Agent such Lender’s Pro Rata Share (determined as of the time that the unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided, that the unreimbursed expense or indemnified payment, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent in its capacity as such.

(d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to actual or direct damages) arising out of, in connection with or as a result of, this Agreement or any agreement or instrument contemplated hereby, the transactions contemplated therein, any Term Loan or the use of proceeds thereof.

(e) All amounts due under this Section 10.3 shall be payable promptly after written demand therefor.

Section 10.4. Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender, and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section.

(b) Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Term Loan Commitment and the Term Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i) Minimum Amounts.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section 10.4, from and after the effective date specified in each Assignment and Acceptance, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Acceptance, 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 Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance 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 2.18, 2.19, 2.20 and 10.3 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph 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 paragraph (d) of this Section 10.4.

(c) The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in Atlanta, Georgia a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Term Loan Commitments of, and principal amount of the Term 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. Information contained in the Register with respect to any Lender shall be available for inspection by such Lender at any reasonable time and from time to time upon reasonable prior notice; information contained in the Register shall also be available for inspection by the Borrower at any reasonable time and from time to time upon reasonable prior notice. In establishing and maintaining the Register, the Administrative Agent shall serve as the Borrower’s agent solely for tax purposes and solely with respect to the actions described in this Section, and the Borrower hereby agrees that, to the extent SunTrust Bank serves in such capacity, SunTrust Bank and its officers, directors, employees, agents, sub-agents and affiliates shall constitute “Indemnitees.”

(d) Any Lender may at any time, without the consent of, or notice to, the Borrower, the Administrative Agent sell participations to any Person (other than a natural person, 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 Term Loan Commitment and/or the Term 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. 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, modification or waiver with respect to the following to the extent affecting such Participant: (i) increase the Term Loan Commitment of such Lender, (ii) reduce the principal amount of any Term Loan owing to such Lender or reduce the rate of interest thereon, or reduce any fees payable to such Lender hereunder, (iii) postpone the date fixed for any payment of any principal of, or interest on, any Term Loan owing to any Lender or interest thereon or any fees payable to such Lender hereunder, or postpone the scheduled date for the termination or reduction of the Term Loan Commitment of such Lender, provided, however, that this clause (iii) shall not apply to the postponement of the date fixed for, or the waiver of any requirement by the Borrower to make, any optional prepayment Section 2.11 or any mandatory prepayment under Section 2.12 (it being understood that such postponement or waiver shall be effective with the written consent of the Required Lenders), (iv) change Section 2.21(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, (v) change any of the provisions of this Section 10.4 or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders which are required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder; or (vi) release all or substantially all collateral (if any) securing any of the Obligations. Subject to paragraph (e) of this Section 10.4, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.18, 2.19, and 2.20 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section 10.4. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.7 as though it were a Lender, provided such Participant agrees to be subject to Section 2.21 as though it were a Lender.

(e) A Participant shall not be entitled to receive any greater payment under Section 2.18 and Section 2.20 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant, after disclosure of such greater payment, is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.20 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.20(e) as though it were a Lender.

(f) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including without limitation 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.

Section 10.5. Governing Law; Jurisdiction; Consent to Service of Process.

(a) This Agreement and the other Loan Documents shall be construed in accordance with and be governed by the law (without giving effect to the conflict of law principles thereof except for Sections 5-1401 and 5-1402 of the New York General Obligations Law) of the State of New York.

(b) The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the United States District Court of the Southern District of New York, and of the Supreme Court of the State of New York sitting in New York county and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or any other Loan Document or the transactions contemplated hereby or thereby, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York state court or, to the extent permitted by applicable law, such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Loan Document shall affect any right that the Administrative Agent or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against the Borrower or its properties in the courts of any jurisdiction.

(c) The Borrower irrevocably and unconditionally waives any objection which it may now or hereafter have to the laying of venue of any such suit, action or proceeding described in paragraph (b) of this Section 10.5 and brought in any court referred to in paragraph (b) of this Section 10.5. Each of the parties hereto irrevocably waives, to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Agreement irrevocably consents to the service of process in the manner provided for notices in Section 10.1. Nothing in this Agreement or in any other Loan Document will affect the right of any party hereto to serve process in any other manner permitted by law.

Section 10.6. WAIVER OF JURY TRIAL. EACH PARTY HERETO IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Section 10.7. Right of Setoff. In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, each Lender shall have the right, at any time or from time to time upon the occurrence and during the continuance of an Event of Default, without prior notice to the Borrower, any such notice being expressly waived by the Borrower to the extent permitted by applicable law, to set off and apply against all deposits (general or special, time or demand, provisional or final) of the Borrower at any time held or other obligations at any time owing by such Lender or any of its Affiliates to or for the credit or the account of the Borrower against any and all Obligations held by such Lender irrespective of whether such Lender shall have made demand hereunder and although such Obligations may be unmatured. Each Lender agree promptly to notify the Administrative Agent and the Borrower after any such set-off and any application made by such Lender, provided, that the failure to give such notice shall not affect the validity of such set-off and application. Each Lender agrees to apply all amounts collected from any such set-off to the Obligations before applying such amounts to any other Indebtedness or other obligations owed by the Borrower and any of its Subsidiaries to such Lender.

Section 10.8. Counterparts; Integration. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by telecopy or other electronic transmission), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. This Agreement, the Fee Letter, the other Loan Documents, and any separate letter agreement(s) relating to any fees payable to the Administrative Agent constitute the entire agreement among the parties hereto and thereto regarding the subject matters hereof and thereof and supersede all prior agreements and understandings, oral or written, regarding such subject matters.

Section 10.9. Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Term Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Term Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid and so long as the Term Loan Commitments have not expired or terminated. The provisions of Sections 2.18, 2.19, 2.20, and 10.3 and Article IX shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Term Loans, the expiration or termination of and the Term Loan Commitments or the termination of this Agreement or any provision hereof provided that the provisions of Sections 2.18, 2.19, and 2.20 shall only survive and remain in full force and effect until the first anniversary of the Termination Date. All representations and warranties made herein, in the certificates, reports, notices, and other documents delivered pursuant to this Agreement shall survive the execution and delivery of this Agreement and the other Loan Documents, and the making of the Term Loans.

Section 10.10. Severability. Any provision of this Agreement or any other Loan Document held to be illegal, invalid or unenforceable in any jurisdiction, shall, as to such

jurisdiction, be ineffective to the extent of such illegality, invalidity or unenforceability without affecting the legality, validity or enforceability of the remaining provisions hereof or thereof; and the illegality, invalidity or unenforceability of a particular provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

Section 10.11. Confidentiality. Each of the Administrative Agent and each Lender agrees to take normal and reasonable precautions to maintain the confidentiality of any confidential information provided to it by the Borrower or any Subsidiary, except that such information may be disclosed (i) to any Related Party of the Administrative Agent or any such Lender, including without limitation accountants, legal counsel and other advisors with a reasonable need for such information (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 on substantially the same terms as provided herein), (ii) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (iii) to the extent requested by any regulatory agency or authority or self-regulatory body having or claiming authority to regulate or oversee any aspect of the Administrative Agent’s or any Lender’s business or businesses, (iv) to the extent that such information becomes publicly available other than as a result of a breach of this Section 10.11, or which becomes available to the Administrative Agent any Lender or any Related Party of any of the foregoing on a non-confidential basis from a source other than the Borrower, (v) in connection with the exercise of any remedy hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, and (ix) subject to provisions substantially similar to this Section 10.11, to any actual or prospective assignee or Participant, or (vi) with the consent of the Borrower. Any Person required to maintain the confidentiality of any information as provided for in this Section 10.11 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 its own confidential information; provided that, in the case of clauses (ii) or (iii), with the exception of disclosure to bank regulatory authorities, the Administrative Agent and each Lender agree, to the extent practicable and legally permissible, to give the Borrower prompt prior notice so that it may seek a protective order or other appropriate remedy.

Section 10.12. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Term Loan, together with all fees, charges and other amounts which may be treated as interest on such Term Loan under applicable law (collectively, the “Charges”), shall exceed the maximum lawful rate of interest (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by a Lender holding such Term Loan in accordance with applicable law, the rate of interest payable in respect of such Term Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Term Loan but were not payable as a result of the operation of this Section 10.12 shall be cumulated and the interest and Charges payable to such Lender in respect of other Term Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Rate to the date of repayment (to the extent permitted by applicable law), shall have been received by such Lender.

Section 10.13. Patriot Act. The Administrative Agent and each Lender to whom the Patriot Act applies hereby notifies the Borrower that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Patriot Act. The Borrower shall, and shall cause each of its Subsidiaries to, provide to the extent commercially reasonable, such information and take such other actions as are reasonably requested by the Administrative Agent or any Lender in order to assist the Administrative Agent and the Lenders in maintaining compliance with the Patriot Act.

Section 10.14. Non-Recourse to the General Partner and Associated Persons. The Administrative Agent and each Lender agrees on behalf of itself and its successors, assigns and legal representatives, that neither the General Partner nor any Person which is a partner, shareholder, member, owner, officer, director, supervisor, trustee or other principal (collectively, “Associated Persons”) of the Borrower, the General Partner, or any of their respective successors or assigns, shall have any personal liability for the payment or performance of any of the Borrower’s obligations hereunder or under any of the Notes and no monetary or other judgment shall be sought or enforced against the General Partner or any of such Associated Persons or any of their respective successors or assigns. Notwithstanding the foregoing, neither the Administrative Agent nor any Lender shall be deemed barred by this Section 10.14 from asserting any claim against any Person based upon an allegation of fraud or misrepresentation.
