7

Level |  | Total Indebtedness to Total Asset Value |  | Applicable Margin for LIBOR Loans |  | Applicable Margin for Base Rate Loans |

Except to the extent otherwise provided herein: (a) the making of the Loans by the Lenders under Section 2.1.(a) shall be made by the Lenders pro rata according to the amount of their respective Commitments; (b) each payment or prepayment of principal of the Loans by the Borrower shall be made for the account of the Lenders pro rata in accordance with the respective unpaid principal amounts of the Loans held by them, (c) each payment of interest on the Loans by the Borrower shall be made for the account of the Lenders pro rata in accordance with the amounts of interest on such Loans then due and payable to the respective Lenders; and (d) the Conversion and Continuation of the Loans of a particular Type (other than Conversions provided for by Section 4.5.) shall be made pro rata among the Lenders according to their respective Loans and the then current Interest Period for each Lender’s portion of each Loan of such Type shall be coterminous.

Section 3.3. Sharing of Payments, Etc.

If a Lender shall obtain payment of any principal of, or interest on, the Loan made by it to the Borrower under this Agreement, or shall obtain payment on any other Obligation owing by the Borrower or a Loan Party through the exercise of any right of set-off, banker’s lien or counterclaim or similar right or otherwise or through voluntary prepayments directly to a Lender or other payments made by the Borrower to a Lender not in accordance with the terms of this Agreement and such payment should be distributed to the Lenders pro rata in accordance with Section 3.2. or Section 10.3., as applicable, such Lender shall promptly purchase from the other Lenders participations in (or, if and to the extent specified by such Lender, direct interests in) the Loans made by the other Lenders or other Obligations owed to such other Lenders in such amounts, and make such other adjustments from time to time as shall be equitable, to the end that

36

all the Lenders shall share the benefit of such payment (net of any reasonable expenses which may be incurred by such Lender in obtaining or preserving such benefit) pro rata in accordance with Section 3.2. or Section 10.3., as applicable. To such end, all the Lenders shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if such payment is rescinded or must otherwise be restored. The Borrower agrees that any Lender so purchasing a participation (or direct interest) in the Loans or other Obligations owed to such other Lenders may exercise all rights of set-off, banker’s lien, counterclaim or similar rights with respect to such participation as fully as if such Lender were a direct holder of Loans in the amount of such participation. Nothing contained herein shall require any Lender to exercise any such right or shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of the Borrower.

Section 3.4. Several Obligations.

No Lender shall be responsible for the failure of any other Lender to make a Loan or to perform any other obligation to be made or performed by such other Lender hereunder, and the failure of any Lender to make a Loan or to perform any other obligation to be made or performed by it hereunder shall not relieve the obligation of any other Lender to make any Loan or to perform any other obligation to be made or performed by such other Lender.

Section 3.5. Minimum Amounts.

(a) Borrowings and Conversions. Base Rate Loans shall be in an aggregate minimum amount of $1,000,000 and integral multiples of $100,000 in excess thereof. LIBOR Loans shall be in an aggregate minimum amount of $1,000,000 and integral multiples of $1,000,000 in excess of that amount.

(b) Prepayments. Each voluntary prepayment of the Loans shall be in an aggregate minimum amount of $1,000,000 and integral multiples of $500,000 in excess thereof (or, if less, the aggregate principal amount of the Loans then outstanding).

Section 3.6. Administrative and Other Fees.

The Borrower agrees to pay the administrative and other fees of the Agent as may be agreed to in writing by the Borrower and the Agent from time to time.

Section 3.7. Computations.

Unless otherwise expressly set forth herein, any accrued interest on any Loan, any Fees or any other Obligations due hereunder shall be computed on the basis of a year of 360 days and the actual number of days elapsed; provided, however, any accrued interest on any Base Rate Loan shall be computed on the basis of a year of 365 or 366 days, as applicable, and the actual number of days elapsed.

37

Section 3.8. Usury.

In no event shall the amount of interest due or payable on the Loans or other Obligations exceed the maximum rate of interest allowed by Applicable Law and, if any such payment is paid by the Borrower or any other Loan Party or received by any Lender, then such excess sum shall be credited as a payment of principal, unless the Borrower shall notify the respective Lender in writing that the Borrower elects to have such excess sum returned to it forthwith. It is the express intent of the parties hereto that the Borrower not pay and the Lenders not receive, directly or indirectly, in any manner whatsoever, interest in excess of that which may be lawfully paid by the Borrower under Applicable Law.

Section 3.9. Agreement Regarding Interest and Charges.

The parties hereto hereby agree and stipulate that the only charge imposed upon the Borrower for the use of money in connection with this Agreement is and shall be the interest specifically described in Section 2.2.(a)(i) and (ii). Notwithstanding the foregoing, the parties hereto further agree and stipulate that all agency fees, syndication fees, facility fees, closing fees, underwriting fees, default charges, late charges, funding or “breakage” charges, increased cost charges, attorneys’ fees and reimbursement for costs and expenses paid by the Agent or any Lender to third parties or for damages incurred by the Agent or any Lender, in each case in connection with the transactions contemplated by this Agreement and the other Loan Documents, are charges made to compensate the Agent or any such Lender for underwriting or administrative services and costs or losses performed or incurred, and to be performed or incurred, by the Agent and the Lenders in connection with this Agreement and shall under no circumstances be deemed to be charges for the use of money. All charges other than charges for the use of money shall be fully earned and nonrefundable when due.

Section 3.10. Statements of Account.

The Agent will account to the Borrower monthly with a statement of Loans, accrued interest and Fees, charges and payments made pursuant to this Agreement and the other Loan Documents, and such account rendered by the Agent shall be deemed conclusive upon Borrower to the extent the Borrower shall fail to object to such account in writing within 5 Business Days of the receipt thereof. The failure of the Agent to deliver such a statement of accounts shall not relieve or discharge the Borrower from any of its obligations hereunder.

Section 3.11. Defaulting Lenders.

Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by Applicable Law:

(a) Waivers and Amendments. Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definition of Requisite Lenders.

38

(b) Defaulting Lender Waterfall. Any payment of principal, interest, Fees or other amounts received by the Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article X. or otherwise) or received by the Agent from a Defaulting Lender pursuant to Section 3.3. shall be applied at such time or times as may be determined by the Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Agent hereunder; second, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Agent; third, to the payment of any amounts owing to the Agent or the Lenders as a result of any judgment of a court of competent jurisdiction obtained by any Lender or the Agent against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; fourth, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and fifth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made at a time when the conditions set forth in Article V. were satisfied or waived, such payment shall be applied solely to pay the Loans of all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loan of such Defaulting Lender until such time as all Loans are held by the Lenders pro rata in accordance with their respective Credit Percentages. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender pursuant to this subsection shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(c) Defaulting Lender Cure. If the Borrower and the Agent agree in writing that a Lender is no longer a Defaulting Lender, the Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein, such Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Agent may determine to be necessary to cause the Loans to be held pro rata by the Lenders in accordance with their respective Commitment Percentages, whereupon such Lender shall cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to Fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

Section 3.12. Taxes.

(a) Taxes Generally. All payments by the Borrower of principal of, and interest on, the Loans and all other Obligations shall be made free and clear of and without deduction for any present or future excise, stamp or other taxes, fees, duties, levies, imposts, charges, deductions, withholdings or other charges of any nature whatsoever imposed by any taxing authority, but

39

excluding (i) franchise taxes, (ii) any taxes imposed on or measured by any Lender’s assets, net income, receipts or branch profits, (iii) any taxes (other than withholding taxes) with respect to the Agent or a Lender that would not be imposed but for a connection between the Agent or such Lender and the jurisdiction imposing such taxes (other than a connection arising solely by virtue of the activities of the Agent or such Lender pursuant to or in respect of this Agreement or any other Loan Document), (iv) any taxes, fees, duties, levies, imposts, charges, deductions, withholdings or other charges to the extent imposed as a result of the failure of the Agent or a Lender, as applicable, to provide and keep current (to the extent legally able) any certificates, documents or other evidence required to qualify for an exemption from, or reduced rate of, any such taxes fees, duties, levies, imposts, charges, deductions, withholdings or other charges or required by the immediately following subsection (c) to be furnished by the Agent or such Lender, as applicable, (v) any taxes arising after the Agreement Date solely as a result of or attributable to a Lender changing its designated Lending Office after the date such Lender becomes a party hereto, and (vi) any taxes imposed by Sections 1471 through Section 1474 of the Internal Revenue Code (including any official interpretations thereof, collectively “FATCA”) on any “withholdable payment” payable to such recipient as a result of the failure of such recipient to satisfy the applicable requirements as set forth in FATCA after December 31, 2012 (such non-excluded items being collectively called “Taxes”). If any withholding or deduction from any payment to be made by the Borrower hereunder is required in respect of any Taxes pursuant to any Applicable Law, then the Borrower will:

(i) pay directly to the relevant Governmental Authority the full amount required to be so withheld or deducted;

(ii) promptly forward to the Agent an official receipt or other documentation satisfactory to the Agent evidencing such payment to such Governmental Authority; and

(iii) pay to the Agent for its account or the account of the applicable Lender, as the case may be, such additional amount or amounts as is necessary to ensure that the net amount actually received by the Agent or such Lender will equal the full amount that the Agent or such Lender would have received had no such withholding or deduction been required.

(b) Tax Indemnification. If the Borrower fails to pay any Taxes when due to the appropriate Governmental Authority or fails to remit to the Agent, for its account or the account of the respective Lender, as the case may be, the required receipts or other required documentary evidence, the Borrower shall indemnify the Agent and the Lenders for any incremental Taxes, interest or penalties that may become payable by the Agent or any Lender as a result of any such failure. For purposes of this Section, a distribution hereunder by the Agent or any Lender to or for the account of any Lender shall be deemed a payment by the Borrower.

(c) Tax Forms. Prior to the date that any Lender or Participant organized under the laws of a jurisdiction outside the United States of America becomes a party hereto, such Person shall deliver to the Borrower and the Agent such certificates, documents or other evidence, as required by the Internal Revenue Code or Treasury Regulations issued pursuant thereto (including Internal Revenue Service Forms W-8ECI and W-8BEN, as applicable, or appropriate

40

successor forms), properly completed, currently effective and duly executed by such Lender or Participant establishing that payments to it hereunder and under the Notes are (i) not subject to United States Federal backup withholding tax and (ii) not subject to United States Federal withholding tax imposed under the Internal Revenue Code. Each such Lender or Participant shall, to the extent it may lawfully do so, (x) deliver further copies of such forms or other appropriate certifications on or before the date that any such forms expire or become obsolete and after the occurrence of any event requiring a change in the most recent form delivered to the Borrower or the Agent and (y) obtain such extensions of the time for filing, and renew such forms and certifications thereof, as may be reasonably requested by the Borrower or the Agent. The Borrower shall not be required to pay any amount pursuant to the last sentence of subsection (a) above to any Lender or Participant that is organized under the laws of a jurisdiction outside of the United States of America or the Agent, if it is organized under the laws of a jurisdiction outside of the United States of America, if such Lender, Participant or the Agent, as applicable, fails to comply with the requirements of this subsection. If any such Lender or Participant, to the extent it may lawfully do so, fails to deliver the above forms or other documentation, then the Agent may withhold from any payments to be made to such Lender under any of the Loan Documents such amounts as are required by the Internal Revenue Code. If any Governmental Authority asserts that the Agent did not properly withhold or backup withhold, as the case may be, any tax or other amount from payments made to or for the account of any Lender, such Lender shall indemnify the Agent therefor, including all penalties and interest, any taxes imposed by any jurisdiction on the amounts payable to the Agent under this Section, and costs and expenses (including all reasonable fees and disbursements of any law firm or other external counsel and the allocated cost of internal legal services and all disbursements of internal counsel) of the Agent. The obligation of the Lenders under this Section shall survive the termination of the Commitments, repayment of all Obligations and the resignation or replacement of the Agent.

ARTICLE IV. YIELD PROTECTION, ETC.

Section 4.1. Additional Costs; Capital Adequacy.

(a) Additional Costs. The Borrower shall promptly pay to the Agent for the account of a Lender from time to time such amounts as such Lender may determine to be necessary to compensate such Lender for any costs incurred by such Lender that it determines are attributable to its making or maintaining of any LIBOR Loans or its obligation to make any LIBOR Loans hereunder, any reduction in any amount receivable by such Lender under this Agreement or any of the other Loan Documents in respect of any of such LIBOR Loans or such obligation or the maintenance by such Lender of capital in respect of its LIBOR Loans (such increases in costs and reductions in amounts receivable being herein called “Additional Costs”), to the extent any such Additional Costs result from any Regulatory Change that: (i) changes the basis of taxation of any amounts payable to such Lender under this Agreement or any of the other Loan Documents in respect of any of such LIBOR Loans (other than taxes, fees, duties, levies, imposts, charges, deductions, withholdings or other charges which are excluded from the definition of Taxes pursuant to the first sentence of Section 3.12.(a)); or (ii) imposes or modifies any reserve, special deposit or similar requirements (other than Regulation D of the Board of Governors of the Federal Reserve System or other reserve requirement to the extent utilized in the determination of Adjusted LIBOR for such LIBOR Loans) relating to any extensions of credit or other assets of, or any deposits with or other liabilities of, such Lender, or any

41

commitment of such Lender; or (iii) has or would have the effect of reducing the rate of return on capital of such Lender to a level below that which such Lender could have achieved but for such Regulatory Change (taking into consideration such Lender’s policies with respect to capital adequacy).

(b) Lender’s Suspension of LIBOR Loans. Without limiting the effect of the provisions of the immediately preceding subsection (a), if, by reason of any Regulatory Change, any Lender either (i) incurs or would incur Additional Costs based on or measured by the excess above a specified level of the amount of a category of deposits or other liabilities of such Lender that includes deposits by reference to which the interest rate on LIBOR Loans is determined as provided in this Agreement or a category of extensions of credit or other assets of such Lender that includes LIBOR Loans or (ii) becomes subject to restrictions on the amount of such a category of liabilities or assets that it may hold, then, if such Lender so elects by notice to the Borrower (with a copy to the Agent), the obligation of such Lender to Continue, or to Convert Base Rate Loans into, LIBOR Loans, or, if such Lender has become obligated to make any new Loan pursuant to Section 2.9., to honor any obligation to make such new Loan as a LIBOR Loan, shall be suspended until such Regulatory Change ceases to be in effect (in which case the provisions of Section 4.5. shall apply).

(c) Notification and Determination of Additional Costs. Each of the Agent and each Lender agrees to notify the Borrower of any event occurring after the Agreement Date entitling the Agent or such Lender to compensation under any of the preceding subsections of this Section as promptly as practicable; provided, however, the failure of the Agent or any Lender to give such notice shall not release the Borrower from any of its obligations hereunder (and in the case of a Lender, to the Agent). The Agent or such Lender agrees to furnish to the Borrower (and in the case of a Lender, to the Agent) a certificate setting forth the basis and amount of each request by the Agent or such Lender for compensation under this Section. Absent manifest error, determinations by the Agent or any Lender of the effect of any Regulatory Change shall be conclusive, provided that such determinations are made on a reasonable basis and in good faith.

Section 4.2. Suspension of LIBOR Loans.

Anything herein to the contrary notwithstanding, if, on or prior to the determination of LIBOR for any Interest Period:

(a) the Agent reasonably determines (which determination shall be conclusive) that by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining Adjusted LIBOR for such Interest Period; or

(b) the Agent reasonably determines (which determination shall be conclusive) that Adjusted LIBOR will not adequately and fairly reflect the cost to the Lenders of making or maintaining LIBOR Loans for such Interest Period;

then the Agent shall give the Borrower and each Lender prompt notice thereof and, so long as such condition remains in effect, the Lenders shall be under no obligation to Continue LIBOR Loans or Convert Loans into LIBOR Loans, or, if such Lender has become obligated to make

42

any new Loan pursuant to Section 2.9., to honor any obligation to make such new Loan as a LIBOR Loan, and the Borrower shall, on the last day of each current Interest Period for each outstanding LIBOR Loan, either repay such Loan or Convert such Loan into a Base Rate Loan.

Section 4.3. Illegality.

Notwithstanding any other provision of this Agreement, if any Lender shall reasonably determine (which determination shall be conclusive and binding) that it has become unlawful for such Lender to maintain LIBOR Loans hereunder, or, if such Lender has become obligated to make any new Loan pursuant to Section 2.9., to honor any obligation to make such new Loan as a LIBOR Loan, then such Lender shall promptly notify the Borrower thereof (with a copy to the Agent) and such Lender’s obligation to Continue, or to Convert Loans of any other Type into, LIBOR Loans, or to make such new Loan as a LIBOR Loan, shall be suspended until such time as such Lender may again maintain LIBOR Loans (in which case the provisions of Section 4.5. shall be applicable).

Section 4.4. Compensation.

The Borrower shall pay to the Agent for the account of each Lender, upon the request of such Lender through the Agent, such amount or amounts as shall be sufficient (in the reasonable opinion of such Lender) to compensate it for any loss, cost or expense that such Lender reasonably determines is attributable to:

(a) any payment or prepayment (whether mandatory or optional) of a LIBOR Loan, or Conversion of a LIBOR Loan, made by such Lender for any reason (including, without limitation, acceleration) on a date other than the last day of the Interest Period for such Loan; or

(b) any failure by the Borrower for any reason (including, without limitation, the failure of any of the applicable conditions precedent specified in Article V. to be satisfied) to borrow a LIBOR Loan from such Lender on the requested date for such borrowing, or to Convert a Base Rate Loan into a LIBOR Loan or Continue a LIBOR Loan on the requested date of such Conversion or Continuation.

Upon the Borrower’s request, any Lender requesting compensation under this Section shall provide the Borrower with a statement setting forth the basis for requesting such compensation and the method for determining the amount thereof. Absent manifest error, determinations by any Lender in any such statement shall be conclusive, provided that such determinations are made on a reasonable basis and in good faith.

Section 4.5. Treatment of Affected Loans.

If the obligation of any Lender to make a new Loan pursuant to Section 2.9. as a LIBOR Loan or to Continue, or to Convert Base Rate Loans into, LIBOR Loans shall be suspended pursuant to Section 4.1.(b), 4.2. or 4.3., then such Lender’s LIBOR Loans shall be automatically Converted into Base Rate Loans on the last day(s) of the then current Interest Period(s) for LIBOR Loans (or, in the case of a Conversion required by Section 4.1.(b) or 4.3., on such earlier

43

date as such Lender may specify to the Borrower with a copy to the Agent) and, unless and until such Lender gives notice as provided below that the circumstances specified in Section 4.1. or 4.3. that gave rise to such Conversion no longer exist:

(i) to the extent that such Lender’s LIBOR Loans have been so Converted, all payments and prepayments of principal that would otherwise be applied to such Lender’s LIBOR Loans shall be applied instead to its Base Rate Loans; and

(ii) any portion of such Lender’s Loan that would otherwise be Continued by such Lender as a LIBOR Loan shall be Continued instead as a Base Rate Loan, any Base Rate Loan of such Lender that would otherwise be Converted into a LIBOR Loan shall remain as a Base Rate Loan, and any new Loan to be made pursuant to Section 2.9. that would otherwise be made as a LIBOR Loan shall be made as a Base Rate Loan.

If such Lender gives notice to the Borrower (with a copy to the Agent) that the circumstances specified in Section 4.1. or 4.3. that gave rise to the Conversion of such Lender’s LIBOR Loans pursuant to this Section no longer exist (which such Lender agrees to do promptly upon such circumstances ceasing to exist) at a time when LIBOR Loans made by other Lenders are outstanding, then such Lender’s Base Rate Loans shall be automatically Converted, on the first day(s) of the next succeeding Interest Period(s) for such outstanding LIBOR Loans, to the extent necessary so that, after giving effect thereto, all Loans held by the Lenders holding LIBOR Loans and by such Lender are held pro rata (as to principal amounts, Types and Interest Periods) in accordance with the respective unpaid principal amount of the Loan held by each Lender.

Section 4.6. Change of Lending Office.

Each Lender agrees that it will use reasonable efforts to designate an alternate Lending Office with respect to any of its Loan affected by the matters or circumstances described in Sections 3.12., 4.1. or 4.3. to reduce the liability of the Borrower or avoid the results provided thereunder, so long as such designation is not disadvantageous to such Lender as determined by such Lender in its sole discretion, except that such Lender shall have no obligation to designate a Lending Office located in the United States of America.

Section 4.7. Assumptions Concerning Funding of LIBOR Loans.

Calculation of all amounts payable to a Lender under this Article IV. shall be made as though such Lender had actually funded LIBOR Loans through the purchase of deposits in the relevant market bearing interest at the rate applicable to such LIBOR Loans in an amount equal to the amount of the LIBOR Loans and having a maturity comparable to the relevant Interest Period; provided, however, that each Lender may fund each of its LIBOR Loans in any manner it sees fit and the foregoing assumption shall be used only for calculation of amounts payable under this Article IV.

ARTICLE VI. REPRESENTATIONS AND WARRANTIES

Section 6.1. Representations and Warranties.

In order to induce the Agent and each Lender to enter into this Agreement and to make the Loans, the Parent and the Borrower represent and warrant to the Agent and each Lender as follows:

(a) Organization; Power; Qualification. Each of the Parent, its Subsidiaries, the Borrower and the other Loan Parties is a corporation, partnership or other legal entity, duly organized or formed, validly existing and in good standing under the jurisdiction of its incorporation or formation, has the power and authority to own or lease its respective properties and to carry on its respective business as now being and hereafter proposed to be conducted and is duly qualified and is in good standing as a foreign corporation, partnership or other legal entity, and authorized to do business, in each jurisdiction in which the character of its properties or the nature of its business requires such qualification or authorization and where the failure to be so qualified or authorized could reasonably be expected to have, in each instance, a Material Adverse Effect.

In such event, the Borrower shall, at the request of the Agent, promptly pay any amount reasonably expended by the Agent in such performance or attempted performance to the Agent, together with interest thereon at the applicable Post-Default Rate from the date of such expenditure until paid. Notwithstanding the foregoing, neither the Agent nor any Lender shall have any liability or responsibility whatsoever for the performance of any obligation of the Borrower under this Agreement or any other Loan Document.

Section 10.5. Rights Cumulative.

The rights and remedies of the Agent and the Lenders under this Agreement and each of the other Loan Documents shall be cumulative and not exclusive of any rights or remedies which any of them may otherwise have under Applicable Law. In exercising their respective rights and remedies the Agent and the Lenders may be selective and no failure or delay by the Agent or any of the Lenders in exercising any right shall operate as a waiver of it, nor shall any single or partial exercise of any power or right preclude its other or further exercise or the exercise of any other power or right.

ARTICLE XI. THE AGENT

Section 11.1. Authorization and Action.

Each Lender hereby appoints and authorizes the Agent to take such action as contractual representative on such Lender’s behalf and to exercise such powers under this Agreement and the other Loan Documents as are specifically delegated to the Agent by the terms hereof and thereof, together with such powers as are reasonably incidental thereto. Not in limitation of the foregoing, each Lender authorizes and directs the Agent to enter into the Loan Documents for the benefit of the Lenders. Each Lender hereby agrees that, except as otherwise set forth herein, any action taken by the Requisite Lenders in accordance with the provisions of this Agreement or the Loan Documents, and the exercise by the Requisite Lenders of the powers set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all of the Lenders. Nothing herein shall be construed to deem the Agent a trustee or fiduciary for any Lender nor to impose on the Agent duties or obligations other than those expressly provided for herein. At the request of a Lender, the Agent will forward to such Lender copies or, where appropriate, originals of the documents delivered to the Agent pursuant to this Agreement or the other Loan Documents. The Agent will also furnish to any Lender, upon the request of such Lender, a copy of any certificate or notice furnished to the Agent by the Borrower, any Loan Party or any other Affiliate of the Borrower, pursuant to this Agreement or any other Loan Document not already delivered to such Lender pursuant to the terms of this

71

Agreement or any such other Loan Document. As to any matters not expressly provided for by the Loan Documents (including, without limitation, enforcement or collection of any of the Obligations), the Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Requisite Lenders (or all of the Lenders if explicitly required under any other provision of this Agreement), and such instructions shall be binding upon all Lenders and all holders of any of the Obligations; provided, however, that, notwithstanding anything in this Agreement to the contrary, the Agent shall not be required to take any action which exposes the Agent to personal liability or which is contrary to this Agreement or any other Loan Document or Applicable Law. Not in limitation of the foregoing, the Agent shall not exercise any right or remedy it or the Lenders may have under any Loan Document upon the occurrence of a Default or an Event of Default unless the Requisite Lenders have so directed the Agent to exercise such right or remedy.

Section 11.2. Agent’s Reliance, Etc.

Notwithstanding any other provisions of this Agreement or any other Loan Documents, neither the Agent nor any of its directors, officers, agents, employees or counsel shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement or any other Loan Document, except for its or their own gross negligence or willful misconduct as determined by a court of competent jurisdiction in a final, non-appealable judgment. Without limiting the generality of the foregoing, the Agent: (a) may treat the payee of any Note as the holder thereof until the Agent receives written notice of the assignment or transfer thereof signed by such payee and in form satisfactory to the Agent; (b) may consult with legal counsel (including its own counsel or counsel for the Borrower or any other Loan Party), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any Lender or any other Person and shall not be responsible to any Lender or any other Person for any statements, warranties or representations made by any Person in or in connection with this Agreement or any other Loan Document; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of any of this Agreement or any other Loan Document or the satisfaction of any conditions precedent under this Agreement or any Loan Document on the part of the Borrower or other Persons or inspect the property, books or records of the Borrower or any other Person; (e) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other Loan Document, any other instrument or document furnished pursuant thereto or any collateral covered thereby or the perfection or priority of any Lien in favor of the Agent on behalf of the Lenders in any such collateral; and (f) shall incur no liability under or in respect of this Agreement or any other Loan Document by acting upon any notice, consent, certificate or other instrument or writing (which may be by telephone or telecopy) believed by it to be genuine and signed, sent or given by the proper party or parties.

Section 11.3. Notice of Defaults.

The Agent shall not be deemed to have knowledge or notice of the occurrence of a Default or Event of Default unless the Agent has received notice from a Lender, the Parent or the

72

Borrower referring to this Agreement, describing with reasonable specificity such Default or Event of Default and stating that such notice is a “notice of default.” If any Lender (excluding the Lender which is also serving as the Agent) becomes aware of any Default or Event of Default, it shall promptly send to the Agent such a “notice of default.” Further, if the Agent receives such a “notice of default”, the Agent shall give prompt notice thereof to the Lenders.

Section 11.4. KeyBank as Lender.

KeyBank, as a Lender, shall have the same rights and powers under this Agreement and any other Loan Document as any other Lender and may exercise the same as though it were not the Agent; and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include KeyBank in each case in its individual capacity. KeyBank and its Affiliates may each accept deposits from, maintain deposits or credit balances for, invest in, lend money to, act as trustee under indentures of, serve as financial advisor to, and generally engage in any kind of business with, the Parent, the Borrower, any other Loan Party or any other Affiliate thereof as if it were any other bank and without any duty to account therefor to the other Lenders. Further, the Agent and any Affiliate of the Agent may accept fees and other consideration from the Parent or the Borrower for services in connection with this Agreement and otherwise without having to account for the same to the other Lenders. The Lenders acknowledge that, pursuant to such activities, KeyBank or its Affiliates may receive information regarding the Parent, the Borrower, other Loan Parties, other Subsidiaries and other Affiliates (including information that may be subject to confidentiality obligations in favor of such Person) and acknowledge that the Agent shall be under no obligation to provide such information to them.

Section 11.5. Approvals of Lenders.

All communications from the Agent to any Lender requesting such Lender’s determination, consent, approval or disapproval (a) shall be given in the form of a written notice to such Lender, (b) shall be accompanied by a description of the matter or issue as to which such determination, approval, consent or disapproval is requested, or shall advise such Lender where information, if any, regarding such matter or issue may be inspected, or shall otherwise describe the matter or issue to be resolved, (c) shall include, if reasonably requested by such Lender and to the extent not previously provided to such Lender, written materials and a summary of all oral information provided to the Agent by the Parent and the Borrower in respect of the matter or issue to be resolved, and (d) shall include the Agent’s recommended course of action or determination in respect thereof. Each Lender shall reply promptly, but in any event within 10 Business Days (or such lesser or greater period as may be specifically required under the Loan Documents) of receipt of such communication. Except as otherwise provided in this Agreement, unless a Lender shall give written notice to the Agent that it specifically objects to the recommendation or determination of the Agent (together with a written explanation of the reasons behind such objection) within the applicable time period for reply (which shall be no less than 10 Business Days), such Lender shall be deemed to have conclusively approved of or consented to such recommendation or determination.

73

Section 11.6. Lender Credit Decision, Etc.

Each Lender expressly acknowledges and agrees that neither the Agent nor any of its officers, directors, employees, agents, counsel, attorneys-in-fact or other Affiliates of the Agent has made any representations or warranties as to the financial condition, operations, creditworthiness, solvency or other information concerning the business or affairs of the Borrower, any other Loan Party, any Subsidiary or any other Person to such Lender and that no act by the Agent hereafter taken, including any review of the affairs of the Parent, the Borrower, any other Loan Party or any other Subsidiary of the Parent or the Borrower, shall be deemed to constitute any such representation or warranty by the Agent to any Lender. Each Lender acknowledges that it has made its own credit and legal analysis and decision to enter into this Agreement and the transactions contemplated hereby, independently and without reliance upon the Agent, any other Lender or counsel to the Agent, or any of their respective officers, directors, employees and agents, and based on the financial statements of the Parent, the Borrower, the Subsidiaries or any other Affiliate thereof, and inquiries of such Persons, its independent due diligence of the business and affairs of the Borrower, the Loan Parties, the Subsidiaries of the Parent and the Borrower and other Persons, its review of the Loan Documents, the legal opinions required to be delivered to it hereunder, the advice of its own counsel and such other documents and information as it has deemed appropriate. Each Lender also acknowledges that it will, independently and without reliance upon the Agent, any other Lender or counsel to the Agent or any of their respective officers, directors, employees and agents, and based on such review, advice, documents and information as it shall deem appropriate at the time, continue to make its own decisions in taking or not taking action under the Loan Documents. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Agent under this Agreement or any of the other Loan Documents, the Agent shall have no duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, financial and other condition or creditworthiness of the Borrower, any other Loan Party or any other Affiliate thereof which may come into possession of the Agent, or any of its officers, directors, employees, agents, attorneys-in-fact or other Affiliates. Each Lender acknowledges that the Agent’s legal counsel in connection with the transactions contemplated by this Agreement is only acting as counsel to the Agent and is not acting as counsel to such Lender.

Section 11.7. Indemnification of Agent.

Each Lender agrees to indemnify the Agent (to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so) pro rata in accordance with such Lender’s respective Credit Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may at any time be imposed on, incurred by, or asserted against the Agent (in its capacity as Agent but not as a Lender) in any way relating to or arising out of the Loan Documents, any transaction contemplated hereby or thereby or any action taken or omitted by the Agent under the Loan Documents (collectively, “Indemnifiable Amounts”); provided, however, that no Lender shall be liable for any portion of such Indemnifiable Amounts to the extent resulting from the Agent’s gross negligence or willful misconduct as determined by a court of competent jurisdiction in a final, non-appealable

74

judgment or if the Agent fails to follow the written direction of the Requisite Lenders (or all of the Lenders if expressly required hereunder) unless such failure results from the Agent following the advice of counsel to the Agent of which advice the Lenders have received notice. Without limiting the generality of the foregoing but subject to the preceding proviso, each Lender agrees to reimburse the Agent (to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so), promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees of the counsel(s) of the Agent’s own choosing) incurred by the Agent in connection with the preparation, negotiation, execution, or enforcement of, or legal advice with respect to the rights or responsibilities of the parties under, the Loan Documents, any suit or action brought by the Agent to enforce the terms of the Loan Documents and/or collect any Obligations, any “lender liability” suit or claim brought against the Agent and/or the Lenders, and any claim or suit brought against the Agent, and/or the Lenders arising under any Environmental Laws. Such out-of-pocket expenses (including counsel fees) shall be advanced by the Lenders on the request of the Agent notwithstanding any claim or assertion that the Agent is not entitled to indemnification hereunder upon receipt of an undertaking by the Agent that the Agent will reimburse the Lenders if it is actually and finally determined by a court of competent jurisdiction that the Agent is not so entitled to indemnification. The agreements in this Section shall survive the payment of the Loans and all other amounts payable hereunder or under the other Loan Documents and the termination of this Agreement. If the Borrower shall reimburse the Agent for any Indemnifiable Amount following payment by any Lender to the Agent in respect of such Indemnifiable Amount pursuant to this Section, the Agent shall share such reimbursement on a ratable basis with each Lender making any such payment.

Section 11.8. Successor Agent.

The Agent may resign at any time as Agent under the Loan Documents by giving written notice thereof to the Lenders and the Borrower. The Agent may be removed as Agent under the Loan Documents for gross negligence or willful misconduct upon 30-day’s prior written notice by all Lenders (other than the Lender then acting as Agent). Upon any such resignation or removal, the Requisite Lenders shall have the right to appoint a successor Agent which appointment shall, provided no Default or Event of Default exists, be subject to the Borrower’s approval, which approval shall not be unreasonably withheld or delayed (except that the Borrower shall, in all events, be deemed to have approved each Lender and its Affiliates as a successor Agent). If no successor Agent shall have been so appointed in accordance with the immediately preceding sentence, and shall have accepted such appointment, within 30 days after the resigning Agent’s giving of notice of resignation or the giving of notice of the removal of the Agent, then the resigning or removed Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be a Lender, if any Lender shall be willing to serve, and otherwise shall be a commercial bank having total combined assets of at least $50,000,000,000; provided, the resigning or removed Agent shall continue to serve as Agent until such time as a successor Agent shall have accepted such appointment. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations under the Loan Documents; provided, however, such retiring Agent shall not be relieved from any obligations arising prior to its discharge the extent resulting from the Agent’s gross negligence or willful misconduct as

75

determined by a court of competent jurisdiction in a final, non-appealable judgment or from the failure by the Agent to follow the written direction of the Requisite Lenders (or all of the Lenders if expressly required hereunder) unless such failure results from the Agent following the advice of counsel to the Agent of which advice the Lenders have received notice. After any Agent’s resignation or removal hereunder as Agent, the provisions of this Article XI. shall continue to inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under the Loan Documents.

Section 11.9. Titled Agents.

Each of the Titled Agents in each such respective capacity, assumes no responsibility or obligation hereunder, including, without limitation, for servicing, enforcement or collection of any of the Loans, nor any duties as an agent hereunder for the Lenders. The titles of “Joint Lead Arranger”, “Joint Book Runner”, “Co-Syndication Agent”, “Co-Documentation Agent” and “Managing Agent” are solely honorific and imply no fiduciary responsibility on the part of the Titled Agents to the Agent, the Borrower or any Lender and the use of such titles does not impose on the Titled Agents any duties or obligations greater than those of any other Lender or entitle the Titled Agents to any rights other than those to which any other Lender is entitled.

Section 12.3. Setoff.

Subject to Section 3.3. and in addition to any rights now or hereafter granted under Applicable Law and not by way of limitation of any such rights, the Agent, each Lender and each Participant is hereby authorized by the Borrower, at any time or from time to time during the continuance of an Event of Default, without prior notice to the Borrower or to any other Person, any such notice being hereby expressly waived, but in the case of a Lender or Participant subject to receipt of the prior written consent of the Agent exercised in its sole discretion, to set off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, indebtedness evidenced by certificates of deposit, whether matured or unmatured) and any other indebtedness at any time held or owing by the Agent, such Lender or any Affiliate of the Agent or such Lender, to or for the credit or the account of the Borrower against and on account of any of the Obligations, irrespective of whether or not any or all of the Loans and all other Obligations have been declared to be, or have otherwise become, due and payable as permitted by Section 10.2., and although such obligations shall be contingent or unmatured.

Section 12.4. Litigation; Jurisdiction; Other Matters; Waivers.

(a) EACH PARTY HERETO ACKNOWLEDGES THAT ANY DISPUTE OR CONTROVERSY BETWEEN OR AMONG THE PARENT, THE BORROWER, THE AGENT OR ANY OF THE LENDERS WOULD BE BASED ON DIFFICULT AND COMPLEX ISSUES OF LAW AND FACT AND WOULD RESULT IN DELAY AND EXPENSE TO THE PARTIES. ACCORDINGLY, TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE LENDERS, THE AGENT, THE PARENT AND THE BORROWER HEREBY WAIVES ITS RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING OF ANY KIND OR NATURE IN ANY COURT OR TRIBUNAL IN WHICH AN ACTION MAY BE COMMENCED BY OR AGAINST ANY PARTY HERETO ARISING OUT OF THIS AGREEMENT, THE NOTES, OR ANY OTHER LOAN DOCUMENT OR BY REASON OF

Section 12.5. Successors and Assigns.

(a) Successors and Assigns Generally. 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 neither the Borrower nor the Parent may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Agent and each Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of the immediately following subsection (b), (ii) by way of participation in accordance with the provisions of the immediately following subsection (d) or (iii) by way of pledge or assignment of a security interest subject to the restrictions of the immediately following subsection (f). Subject to the last sentence of the immediately following subsection (b), any attempted assignment or transfer by any party hereto not permitted by clauses (i) through (iii) of the immediately preceding sentence shall be null and void. Nothing in this Agreement, expressed or implied,

79

shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in the immediately following subsection (d) and, to the extent expressly contemplated hereby, the Related Parties of the Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

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

(i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of an assigning Lender’s Loan at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(B) in any case not described in the immediately preceding subsection (A), the aggregate amount of the principal outstanding balance of the Loan of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance Agreement with respect to such assignment is delivered to the Agent or, if “Trade Date” is specified in the Assignment and Acceptance Agreement, as of the Trade Date) shall not be less than $10,000,000, unless each of the Agent and, so long as no Default or Event of Default shall exist, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed); provided, however, that if, after giving effect to such assignment, the outstanding principal balance of the Loan of such assigning Lender would be less than $10,000,000 then such assigning Lender shall assign the entire amount of its Loan at the time owing to it.

(ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan assigned.

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by clause (i)(B) of this subsection (b) and, in addition:

(A) the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (x) a Default or Event of Default shall exist at the time of such assignment or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Agent within 5 Business Days after having received notice thereof; and

80

(B) the consent of the Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments in respect of a Loan if such assignment is to a Person that is not already a Lender holding a Loan, an Affiliate of such a Lender or an Approved Fund with respect to such a Lender.

(iv) Assignment and Acceptance Agreement; Notes. The parties to each assignment shall execute and deliver to the Agent an Assignment and Acceptance Agreement, together with a processing and recordation fee of $3,500 for each assignment, and the assignee, if it is not a Lender, shall deliver to the Agent an Administrative Questionnaire. If requested by the transferor Lender or the Eligible Assignee, upon the consummation of any assignment, the transferor Lender, the Agent and the Borrower shall make appropriate arrangements so that new Notes are issued to the Eligible Assignee and such transferor Lender, as appropriate.

(v) No Assignment to Certain Persons. No such assignment shall be made to (A) the Parent, the Borrower or any of the Parent or the Borrower’s Affiliates or Subsidiaries or (B) any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B).

(vi) No Assignment to Natural Persons. No such assignment shall be made to a natural person.

Subject to acceptance and recording thereof by the Agent pursuant to the immediately following subsection (c), from and after the effective date specified in each Assignment and Acceptance Agreement, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Acceptance Agreement, 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 Agreement, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance Agreement 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 4.4., 12.2. and 12.9. and the other provisions of this Agreement and the other Loan Documents as provided in Section 12.10. 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 the immediately following subsection (d).

(c) Register. The Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at the Principal Office a copy of each Assignment and Acceptance Agreement delivered to it and a register for the recordation of the names and addresses of the Lenders, and the principal amount of the Loan owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to

81

the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of the Loan 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 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 (w) decrease the amount of such Lender’s Loan, (x) extend the date fixed for the payment of principal on the Loans or portions thereof owing to such Lender, (y) reduce the rate at which interest is payable thereon or (z) release any Guarantor from its Obligations under the Guaranty (except as otherwise permitted under Section 7.12.(b)). Subject to the immediately following subsection (e), the Borrower agrees that each Participant shall be entitled to the benefits of Sections 3.12., 4.1., 4.4. to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by Applicable Law, each Participant also shall be entitled to the benefits of Section 12.3. as though it were a Lender, provided such Participant agrees to be subject to Section 3.3. as though it were a Lender.

(e) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Sections 3.12., 4.1. and 4.4. 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 is made with the Borrower’s prior written consent which consent may be withheld in the Borrower’s sole discretion. A Participant that is organized under the laws of a jurisdiction outside of the United States of America shall not be entitled to the benefits of Section 3.12. unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower and the Agent, to comply with Section 3.12.(c) as though it were a Lender.

(f) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(g) No Registration. Each Lender agrees that, without the prior written consent of the Borrower and the Agent exercised in their sole discretion, it will not make any assignment hereunder in any manner or under any circumstances that would require registration or

82

qualification of, or filings in respect of, any Loan or Note under the Securities Act or any other securities laws of the United States of America or of any other jurisdiction.

Section 12.6. Amendments.

(a) Except as otherwise expressly provided in this Agreement, any consent or approval required or permitted by this Agreement or any other Loan Document to be given by the Lenders may be given, and any term of this Agreement or of any other Loan Document may be amended, and the performance or observance by the Borrower or any other Loan Party or any Subsidiary of any terms of this Agreement or such other Loan Document or the continuance of any Default or Event of Default may be waived (either generally or in a particular instance and either retroactively or prospectively) with, but only with, the written consent of the Requisite Lenders (and, in the case of an amendment to any Loan Document, the written consent of each Loan Party a party thereto).

(b) Notwithstanding the foregoing, without the prior written consent of each Lender adversely affected thereby, no amendment, waiver or consent shall do any of the following:

(i) decrease the principal amount of the Loans or subject the Lenders to any additional obligations;

(ii) decrease the interest that has accrued or the interest rates that will be charged on the outstanding principal amount of any Loans or other Obligations;

(iii) reduce the amount of any Fees payable hereunder or postpone any date fixed for payment thereof;

(iv) modify the definition of the term “Termination Date” or otherwise postpone any date fixed for any payment of any principal of, or interest on, any Loans or any other Obligations (including the waiver of any Default or Event of Default as a result of the nonpayment of any such Obligations as and when due);

(v) modify the definition of “Credit Percentage” or amend or otherwise modify the provisions of Section 3.2.;

(vi) modify the definition of the term “Requisite Lenders” or otherwise modify in any other manner the number or percentage of the Lenders required to make any determinations or waive any rights hereunder or to amend or otherwise modify any provision hereof, including without limitation, any modification of this Section 12.6. if such modification would have such effect;

(vii) release any Guarantor from its obligations under the Guaranty (except as otherwise permitted under Section 7.12.(b));

(viii) amend or otherwise modify the provisions of Section 10.3.; or

83

(ix) increase the number of Interest Periods permitted with respect to Loans under Section 2.3.

(c) No amendment, waiver or consent, unless in writing and signed by the Agent, in such capacity, in addition to the Lenders required hereinabove to take such action, shall affect the rights or duties of the Agent under this Agreement or any of the other Loan Documents.

(d) No waiver shall extend to or affect any obligation not expressly waived or impair any right consequent thereon and any amendment, waiver or consent shall be effective only in the specific instance and for the specific purpose set forth therein. No course of dealing or delay or omission on the part of the Agent or any Lender in exercising any right shall operate as a waiver thereof or otherwise be prejudicial thereto. Any Event of Default occurring hereunder shall continue to exist until such time as such Event of Default is waived in writing in accordance with the terms of this Section, notwithstanding any attempted cure or other action by the Borrower, any other Loan Party or any other Person subsequent to the occurrence of such Event of Default. Except as otherwise explicitly provided for herein or in any other Loan Document, no notice to or demand upon the Borrower shall entitle the Borrower to any other or further notice or demand in similar or other circumstances.

Section 12.7. Nonliability of Agent and Lenders.

The relationship between the Borrower and the Lenders and the Agent shall be solely that of borrower and lender. Neither the Agent nor any Lender shall have any fiduciary responsibilities to the Parent or the Borrower and no provision in this Agreement or in any of the other Loan Documents, and no course of dealing between or among any of the parties hereto, shall be deemed to create any fiduciary duty owing by the Agent or any Lender to any Lender, the Parent, the Borrower, any Subsidiary of the Parent or the Borrower or any other Loan Party. Neither the Agent nor any Lender undertakes any responsibility to the Borrower or the Parent to review or inform the Borrower or the Parent of any matter in connection with any phase of the Borrower’s or Parent’s business or operations.

Section 12.8. Confidentiality.

The Agent and each Lender shall use reasonable efforts to assure that information about the Borrower, the Parent, the other Loan Parties and other Subsidiaries of the Parent and the Borrower, and the Properties thereof and their operations, affairs and financial condition, not generally disclosed to the public, which is furnished to the Agent or any Lender pursuant to the provisions of this Agreement or any other Loan Document, is used only for the purposes of this Agreement and the other Loan Documents and shall not be divulged to any Person other than the Agent, the Lenders, and their respective agents who are actively and directly participating in the evaluation, administration or enforcement of the Loan Documents and other transactions between the Agent or such Lender, as applicable, and the Borrower and the Parent, but in any event the Agent and the Lenders may make disclosure: (a) to any of their respective Affiliates (provided such Affiliates shall agree to keep such information confidential in accordance with the terms of this Section 12.8.); (b) as reasonably requested by any bona fide Eligible Assignee, Participant or other transferee in connection with the contemplated transfer of any Loan or participations therein as permitted hereunder (provided they shall agree to keep such information

84

confidential in accordance with the terms of this Section); (c) as required or requested by any Governmental Authority or representative thereof or pursuant to legal process or in connection with any legal proceedings; (d) to the Agent’s or such Lender’s independent auditors and other professional advisors (provided they shall be notified of the confidential nature of the information); (e) after the happening and during the continuance of an Event of Default, to any other Person, in connection with the exercise by the Agent or the Lenders of rights hereunder or under any of the other Loan Documents; (f) upon Borrower’s prior consent (which consent shall not be unreasonably withheld), to any contractual counter-parties to any swap or similar hedging agreement or to any rating agency; and (g) to the extent such information (x) becomes publicly available other than as a result of a breach of this Section actually known to such Lender to be such a breach or (y) becomes available to the Agent or any Lender on a nonconfidential basis from a source other than the Parent, the Borrower or any Affiliate. Notwithstanding the foregoing, the Agent and each Lender may disclose any such confidential information, upon notice to the Borrower or any other Loan Party, to the extent practicable (provided, that, any failure by the Agent or any Lender to give such notice to the Borrower or any Loan Party shall not subject the Agent or any Lender to any liability which may arise from such failure to give notice), to Governmental Authorities in connection with any regulatory examination of the Agent or such Lender or in accordance with the regulatory compliance policy of the Agent or such Lender.

Section 12.9. Indemnification.

(a) The Borrower shall and hereby agrees to indemnify, defend and hold harmless the Agent, each of the Lenders, any Affiliate of the Agent or any Lender, and their respective directors, officers, shareholders, agents, employees and counsel (each referred to herein as an “Indemnified Party”) from and against any and all of the following (collectively, the “Indemnified Costs”): losses, costs, claims, damages, liabilities, deficiencies, judgments or expenses of every kind and nature (including, without limitation, amounts paid in settlement, court costs and the reasonable fees and disbursements of counsel incurred in connection with any litigation, investigation, claim or proceeding or any advice rendered in connection therewith, but excluding losses, costs, claims, damages, liabilities, deficiencies, judgments or expenses indemnification in respect of which is specifically covered by Section 3.12. or 4.1. or expressly excluded from the coverage of such Sections 3.12. or 4.1.) incurred by an Indemnified Party in connection with, arising out of, or by reason of, any suit, cause of action, claim, arbitration, investigation or settlement, consent decree or other proceeding (the foregoing referred to herein as an “Indemnity Proceeding”) which is in any way related directly or indirectly to: (i) this Agreement or any other Loan Document or the transactions contemplated thereby; (ii) the making of any Loans hereunder; (iii) any actual or proposed use by the Borrower of the proceeds of the Loans; (iv) the Agent’s or any Lender’s entering into this Agreement; (v) the fact that the Agent and the Lenders have established the credit facility evidenced hereby in favor of the Borrower; (vi) the fact that the Agent and the Lenders are creditors of the Borrower and have or are alleged to have information regarding the financial condition, strategic plans or business operations of the Parent, the Borrower and their respective Subsidiaries; (vii) the fact that the Agent and the Lenders are material creditors of the Borrower and are alleged to influence directly or indirectly the business decisions or affairs of the Parent, the Borrower and their respective Subsidiaries or their financial condition; (viii) the exercise of any right or remedy the

85

Agent or the Lenders may have under this Agreement or the other Loan Documents; (ix) any civil penalty or fine assessed by the OFAC against, and all reasonable costs and expenses (including counsel fees and disbursements) incurred in connection with defense thereof by, the Agent or any Lender as a result of conduct of the Borrower, any other Loan Party or any Subsidiary that violates a sanction enforced by the OFAC; or (x) any violation or non-compliance by the Parent, the Borrower or any Subsidiary of any Applicable Law (including any Environmental Law) including, but not limited to, any Indemnity Proceeding commenced by (A) the Internal Revenue Service or state taxing authority or (B) any Governmental Authority or other Person under any Environmental Law, including any Indemnity Proceeding commenced by a Governmental Authority or other Person seeking remedial or other action to cause the Parent, the Borrower or their respective Subsidiaries (or its respective properties) (or the Agent and/or the Lenders as successors to the Borrower) to be in compliance with such Environmental Laws; provided, however, that the Borrower shall not be obligated to indemnify any Indemnified Party for (A) any acts or omissions of such Indemnified Party in connection with matters described in this subsection to the extent arising from the gross negligence or willful misconduct of such Indemnified Party, as determined by a court of competent jurisdiction in a final, non-appealable judgment or (B) Indemnified Costs to the extent arising directly out of or resulting directly from claims of one or more Indemnified Parties against another Indemnified Party.

(b) The Borrower’s indemnification obligations under this Section 12.9. shall apply to all Indemnity Proceedings arising out of, or related to, the foregoing whether or not an Indemnified Party is a named party in such Indemnity Proceeding. In this regard, this indemnification shall cover all Indemnified Costs of any Indemnified Party in connection with any deposition of any Indemnified Party or compliance with any subpoena (including any subpoena requesting the production of documents). This indemnification shall, among other things, apply to any Indemnity Proceeding commenced by other creditors of the Parent, the Borrower or any Subsidiary, any shareholder of the Parent, the Borrower or any Subsidiary (whether such shareholder(s) are prosecuting such Indemnity Proceeding in their individual capacity or derivatively on behalf of the Borrower or the Parent), any account debtor of the Parent, the Borrower or any Subsidiary or by any Governmental Authority. If indemnification is to be sought hereunder by an Indemnified Party, then such Indemnified Party shall notify the Borrower in writing of the commencement of any Indemnity Proceeding; provided, however, that the failure to so notify the Borrower shall not relieve the Borrower from any liability that it may have to such Indemnified Party pursuant to this Section 12.9.

(c) This indemnification shall apply to any Indemnity Proceeding arising during the pendency of any bankruptcy proceeding filed by or against the Parent, the Borrower and/or any Subsidiary.

(d) All out-of-pocket fees and expenses of, and all amounts paid to third-persons by, an Indemnified Party shall be advanced by the Borrower at the request of such Indemnified Party notwithstanding any claim or assertion by the Borrower that such Indemnified Party is not entitled to indemnification hereunder, upon receipt of an undertaking by such Indemnified Party that such Indemnified Party will reimburse the Borrower if it is actually and finally determined by a court of competent jurisdiction that such Indemnified Party is not so entitled to indemnification hereunder.

86

(e) An Indemnified Party may conduct its own investigation and defense of, and may formulate its own strategy with respect to, any Indemnity Proceeding covered by this Section and, as provided above, all Indemnified Costs incurred by such Indemnified Party shall be reimbursed by the Borrower. No action taken by legal counsel chosen by an Indemnified Party in investigating or defending against any such Indemnity Proceeding shall vitiate or in any way impair the obligations and duties of the Borrower hereunder to indemnify and hold harmless each such Indemnified Party; provided, however, that if (i) the Borrower is required to indemnify an Indemnified Party pursuant hereto and (ii) the Borrower has provided evidence reasonably satisfactory to such Indemnified Party that the Borrower has the financial wherewithal to reimburse such Indemnified Party for any amount paid by such Indemnified Party with respect to such Indemnity Proceeding, such Indemnified Party shall not settle or compromise any such Indemnity Proceeding without the prior written consent of the Borrower (which consent shall not be unreasonably withheld or delayed). Notwithstanding the foregoing, an Indemnified Party may settle or compromise any such Indemnity Proceeding without the prior written consent of the Borrower where (x) no monetary relief is sought against such Indemnified Party in such Indemnity Proceeding or (y) there is an allegation of a violation of law by such Indemnified Party.

(f) If and to the extent that the obligations of the Borrower under this Section are unenforceable for any reason, the Borrower hereby agrees to make the maximum contribution to the payment and satisfaction of such obligations which is permissible under Applicable Law.

(g) The Borrower’s obligations under this Section shall survive any termination of this Agreement and the other Loan Documents and the payment in full in cash of the Obligations, and are in addition to, and not in substitution of, any other of their obligations set forth in this Agreement or any other Loan Document to which it is a party.

Section 12.10. Termination; Survival.

This Agreement shall terminate at such time as all Obligations (other than obligations which survive as provided in the following sentence) have been paid and satisfied in full. The indemnities to which the Agent and the Lenders are entitled under the provisions of Sections 3.12., 4.1., 4.4., 11.7., 12.2. and 12.9. and any other provision of this Agreement and the other Loan Documents, and the provisions of Section 12.4., shall continue in full force and effect and shall protect the Agent and the Lenders (i) notwithstanding any termination of this Agreement, or of the other Loan Documents, against events arising before such termination as well as, in the case of Sections 11.7., 12.4. and 12.9., after such termination and (ii) at all times after any such party ceases to be a party to this Agreement with respect to all matters and events existing on or prior to the date such party ceased to be a party to this Agreement.

Section 12.11. Severability of Provisions.

Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective only to the extent of such prohibition or unenforceability without invalidating the remainder of such provision or the remaining provisions or affecting the validity or enforceability of such provision in any other jurisdiction.

87

Section 12.12. GOVERNING LAW.

THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS EXECUTED, AND TO BE FULLY PERFORMED, IN SUCH STATE.

Section 12.13. Counterparts.

This Agreement and any amendments, waivers, consents or supplements may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed an original, but all of which counterparts together shall constitute but one and the same instrument.

Section 12.14. Obligations with Respect to Loan Parties.

The obligations of the Parent and the Borrower to direct or prohibit the taking of certain actions by the other Loan Parties as specified herein shall be absolute and not subject to any defense the Parent or the Borrower may have that the Parent or the Borrower does not control such Loan Parties.

Section 12.15. Limitation of Liability.

Neither the Agent nor any Lender, nor any Affiliate, officer, director, employee, attorney, or agent of the Agent or any Lender shall have any liability with respect to, and the Parent and the Borrower hereby waives, releases, and agrees not to sue any of them upon, any claim for any special, indirect, incidental, or consequential damages suffered or incurred by the Parent or the Borrower in connection with, arising out of, or in any way related to, this Agreement or any of the other Loan Documents, or any of the transactions contemplated by this Agreement or any of the other Loan Documents. Each of the Parent and the Borrower hereby waives, releases, and agrees not to sue the Agent or any Lender or any of the Agent’s or any Lender’s Affiliates, officers, directors, employees, attorneys, or agents for punitive damages in respect of any claim in connection with, arising out of, or in any way related to, this Agreement or any of the other Loan Documents, or any of the transactions contemplated by this Agreement or financed hereby.

Section 12.16. Entire Agreement.

This Agreement, the Notes, and the other Loan Documents referred to herein embody the final, entire agreement among the parties hereto and supersede any and all prior commitments, agreements, representations, and understandings, whether written or oral, relating to the subject matter hereof and thereof and may not be contradicted or varied by evidence of prior, contemporaneous, or subsequent oral agreements or discussions of the parties hereto. There are no oral agreements among the parties hereto.

88

Section 12.17. Construction.

The Agent, the Borrower, the Parent and each Lender acknowledge that each of them has had the benefit of legal counsel of its own choice and has been afforded an opportunity to review this Agreement and the other Loan Documents with its legal counsel and that this Agreement and the other Loan Documents shall be construed as if jointly drafted by the Agent, the Borrower, the Parent and each Lender.

Section 12.18. Patriot Act.

The Lenders and the Agent each 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)), 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 Agent, as applicable, to identify the Borrower in accordance with such Act.

FORM OF OPINION OF COUNSEL

[LETTERHEAD OF COUNSEL TO THE LOAN PARTIES]

February 14, 2012

KeyBank National Association, as Agent

127 Public Square, 8 th Floor

Cleveland, Ohio 44114

Attn: John C. Scott

The Lenders party to the Term Loan

Agreement referred to below

Ladies and Gentlemen:

We have acted as counsel to Corporate Office Properties, L.P., a limited partnership formed under the laws of the State of Delaware (the “Borrower”) in connection with the negotiation, execution and delivery of that certain Term Loan Agreement dated as of February 14, 2012 (the “Term Loan Agreement”), by and among the Borrower, Corporate Office Properties Trust, the financial institutions party thereto and their assignees under Section 12.5. thereof (the “Lenders”), KeyBank National Association, as Agent (the “Agent”), and the other parties thereto. We have also acted as counsel to each of the Guarantors listed on Schedule 1 attached hereto (the “Guarantors”; together with the Borrower, the “Loan Parties”), in connection with the Guaranty and the other Loan Documents identified below to which they are party. Capitalized terms not otherwise defined herein have the respective meaning given them in the Term Loan Agreement.

In these capacities, we have reviewed executed copies of the following:

(a) the Term Loan Agreement;

(b) the Notes;

(c) the Guaranty; and

(d) [list other applicable Loan Documents].

The documents and instruments set forth in items (a) through (d) above are referred to herein as the “Loan Documents”.

F-1

In addition to the foregoing, we have reviewed the [articles or certificate of incorporation, by-laws, declaration of trust, partnership agreement and limited liability company operating agreement, as applicable,] of each Loan Party and certain resolutions of the board of trustees or directors, as applicable, of each Loan Party (collectively, the “Organizational Documents”) and have also examined originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, and other instruments, and made such other investigations of law and fact, as we have deemed necessary or advisable for the purposes of rendering this opinion. In our examination of documents, we assumed the genuineness of all signatures on documents presented to us as originals (other than the signatures of officers of the Loan Parties) and the conformity to originals of documents presented to us as conformed or reproduced copies.

Based upon the foregoing, and subject to all of the qualifications and assumptions set forth herein, we are of the opinion that:

1. The Parent is a real estate investment trust, duly organized, validly existing and in good standing under the laws of the State of Maryland, and has the power to execute and deliver, and to perform its obligations under, the Loan Documents to which it is a party, to own and use its assets, and to conduct its business as presently conducted. The Parent is qualified to transact business as a foreign real estate investment trust in the following jurisdictions: .

2. The Borrower is a limited partnership, duly organized, validly existing and in good standing under the laws of the State of Delaware, and has the power to execute and deliver, and to perform its obligations under, the Loan Documents to which it is a party, to own and use its assets, and to conduct its business as presently conducted. The Borrower is qualified to transact business as a foreign limited partnership in the following jurisdictions: .

3. [Insert separate paragraphs or Guarantors with different corporate structure] Each [Guarantor] is a [corporation, trust, partnership or limited liability company, as applicable,] duly organized or formed, validly existing and in good standing under the laws of the State of its organization or formation and has the power to execute and deliver, and to perform its obligations under, the Loan Documents to which it is a party, to own and use its assets, and to conduct its business as presently conducted. Each [Guarantor] is qualified to transact business as a foreign [corporation, trust, partnership or limited liability company, as applicable,] in the indicated jurisdictions set forth on Schedule I attached hereto.

4. Each Loan Party has duly authorized the execution and delivery of the Loan Documents to which it is a party and the performance by such Loan Party of all of its obligations under each such Loan Document.

5. Each Loan Party has duly executed and delivered the Loan Documents to which it is a party.

F-2

6. The execution and delivery by each Loan Party of the Loan Documents to which it is a party do not, and if each Loan Party were now to perform its obligations under such Loan Documents, such performance would not, result in any:

(a) violation of such Loan Party’s Organizational Documents;

(b) violation of any existing federal or state constitution, statute, regulation, rule, order, or law to which such Loan Party or its assets are subject;

(c) breach or violation of or default under, any agreement, instrument, indenture or other document evidencing any indebtedness for money borrowed or any other material agreement to which, to our knowledge, such Loan Party is bound or under which a Loan Party or its assets is subject;

(d) creation or imposition of a lien or security interest in, on or against the assets of such Loan Party under any agreement, instrument, indenture or other document evidencing any indebtedness for money borrowed or any other material agreement to which, to our knowledge, such Loan Party is bound or under which a Loan Party or its assets is subject; or

(e) violation of any judicial or administrative decree, writ, judgment or order to which, to our knowledge, such Loan Party or its assets are subject.

7. The execution, delivery and performance by each Loan Party of each Loan Document to which it is a party, and the consummation of the transactions thereunder, do not and will not require any registration with, consent or approval of, or notice to, or other action to, with or by, any Governmental Authority of the United States of America or the States of , or .

8. To our knowledge, there are no judgments outstanding against any of the Loan Parties or affecting any of their respective assets, nor is there any litigation or other proceeding against any of the Loan Parties or its assets pending or overtly threatened, could reasonably be expected to have a materially adverse effect on (a) the business, assets, liabilities, condition (financial or otherwise), results of operations or business prospects of the Borrower or any other Loan Party or (b) the validity or enforceability of any of the Loan Documents.

9. None of the Loan Parties is, or, after giving effect to any Loan will be, subject to the Investment Company Act of 1940 or to any federal or state statute or regulation limiting its ability to incur indebtedness for borrowed money.

10. No transfer, mortgage, intangible, documentary stamp or similar taxes are payable by the Agent or the Lenders to the States of or or any political subdivision thereof in connection with (a) the execution and delivery of the Loan Documents or (b) the creation of the Indebtedness and the other Obligations evidenced by any of the Loan Documents.

F-3

11. Assuming that Borrower applies the proceeds of the Loans as provided in the Term Loan Agreement, the transactions contemplated by the Loan Documents do not violate the provisions of Regulations T, U or X of the Board of Governors of the Federal Reserve System of the United States of America.

12. The consideration to be paid to the Agent and the Lenders for the financial accommodations to be provided to the Loan Parties pursuant to the Term Loan Agreement does not violate any law of the States of or relating to interest and usury.

This opinion is limited to the laws of the States of , and and the federal laws of the United States of America, and we express no opinions with respect to the law of any other jurisdiction.

[Other Customary Qualifications/Assumptions/Limitations]

This opinion is furnished to you solely for your benefit in connection with the consummation of the transactions contemplated by the Term Loan Agreement and may not be relied upon by any other Person, other than an Assignee of a Lender, or for any other purpose without our express, prior written consent.

(i) any defect, limitation or insufficiency in the borrowing powers of the Borrower or in the exercise thereof; or

(j) any other circumstance which might otherwise constitute a defense available to, or a discharge of, a Guarantor hereunder (other than indefeasible payment and performance in full).

Section 4. Action with Respect to Guarantied Obligations. The Lenders and the Agent may, at any time and from time to time, without the consent of, or notice to, any Guarantor, and without discharging any Guarantor from its obligations hereunder, take any and all actions described in Section 3 and may otherwise: (a) amend, modify, alter or supplement the terms of any of the Guarantied Obligations, including, but not limited to, extending or shortening the time of payment of any of the Guarantied Obligations or changing the interest rate that may accrue on any of the Guarantied Obligations; (b) amend, modify, alter or supplement the Term Loan Agreement or any other Loan Document; (c) sell, exchange, release or otherwise deal with all, or any part, of any collateral securing any of the Obligations; (d) release any other Loan Party or other Person liable in any manner for the payment or collection of the Guarantied Obligations; (e) exercise, or refrain from exercising, any rights against the Borrower, any other Guarantor or any other Person; and (f) apply any sum, by whomsoever paid or however realized, to the Guarantied Obligations in such order as the Lenders shall elect.

Section 5. Representations and Warranties. Each Guarantor hereby makes to the Agent and the Lenders all of the representations and warranties made by the Borrower with respect to or in any way relating to such Guarantor in the Term Loan Agreement and the other Loan Documents, as if the same were set forth herein in full.

H-3

Section 6. Covenants. Each Guarantor will comply with all covenants which the Borrower is to cause such Guarantor to comply with under the terms of the Term Loan Agreement or any of the other Loan Documents.

Section 7. Waiver. Each Guarantor, to the fullest extent permitted by Applicable Law, hereby waives notice of acceptance hereof or any presentment, demand, protest or notice of any kind, and any other act or thing, or omission or delay to do any other act or thing, which in any manner or to any extent might vary the risk of such Guarantor or which otherwise might operate to discharge such Guarantor from its obligations hereunder.

Section 8. Inability to Accelerate Loan. If the Agent and/or the Lenders are prevented under Applicable Law or otherwise from demanding or accelerating payment of any of the Guarantied Obligations by reason of any automatic stay or otherwise, the Agent and/or the Lenders shall be entitled to receive from each Guarantor, upon demand therefor, the sums which otherwise would have been due had such demand or acceleration occurred.

Section 9. Reinstatement of Guarantied Obligations. If claim is ever made on the Agent or any Lender for repayment or recovery of any amount or amounts received in payment or on account of any of the Guarantied Obligations, and the Agent or such Lender repays all or part of said amount by reason of (a) any judgment, decree or order of any court or administrative body of competent jurisdiction, or (b) any settlement or compromise of any such claim effected by the Agent or such Lender with any such claimant (including the Borrower or a trustee in bankruptcy for the Borrower), then and in such event each Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be binding on it, notwithstanding any revocation hereof or the cancellation of the Term Loan Agreement, any of the other Loan Documents, or any other instrument evidencing any liability of the Borrower, and such Guarantor shall be and remain liable to the Agent or such Lender for the amounts so repaid or recovered to the same extent as if such amount had never originally been paid to the Agent or such Lender.

Section 10. Subrogation. Upon the making by any Guarantor of any payment hereunder for the account of the Borrower, such Guarantor shall be subrogated to the rights of the payee against the Borrower; provided, however, that such Guarantor shall not enforce any right or receive any payment by way of subrogation or otherwise take any action in respect of any other claim or cause of action such Guarantor may have against the Borrower arising by reason of any payment or performance by such Guarantor pursuant to this Guaranty, unless and until all of the Guarantied Obligations have been indefeasibly paid and performed in full. If any amount shall be paid to such Guarantor on account of or in respect of such subrogation rights or other claims or causes of action, such Guarantor shall hold such amount in trust for the benefit of the Agent and the Lenders and shall forthwith pay such amount to the Agent to be credited and applied against the Guarantied Obligations, whether matured or unmatured, in accordance with the terms of the Term Loan Agreement or to be held by the Agent as collateral security for any Guarantied Obligations existing.

Section 11. Payments Free and Clear. All sums payable by each Guarantor hereunder, whether of principal, interest, Fees, expenses, premiums or otherwise, shall be paid in full,

H-4

without set-off or counterclaim or any deduction or withholding whatsoever (including any Taxes), and if any Guarantor is required by Applicable Law or by a Governmental Authority to make any such deduction or withholding, such Guarantor shall pay to the Agent and the Lenders such additional amount as will result in the receipt by the Agent and the Lenders of the full amount payable hereunder had such deduction or withholding not occurred or been required.

Section 12. Set-off. In addition to any rights now or hereafter granted under any of the other Loan Documents or Applicable Law and not by way of limitation of any such rights, each Guarantor hereby authorizes the Agent and each Lender, at any time during the continuance of an Event of Default, without any prior notice to such Guarantor or to any other Person, any such notice being hereby expressly waived, but in the case of a Lender or Participant subject to receipt of the prior written consent of the Agent exercised in its sole discretion, to set off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, indebtedness evidenced by certificates of deposit, whether matured or unmatured) and any other indebtedness at any time held or owing by the Agent, such Lender, or any Affiliate of the Agent or such Lender, to or for the credit or the account of such Guarantor against and on account of any of the Guarantied Obligations, although such obligations shall be contingent or unmatured. Each Guarantor agrees, to the fullest extent permitted by Applicable Law, that any Participant may exercise rights of setoff or counterclaim and other rights with respect to its participation as fully as if such Participant were a direct creditor of such Guarantor in the amount of such participation.

Section 13. Subordination. Each Guarantor hereby expressly covenants and agrees for the benefit of the Agent and the Lenders that all obligations and liabilities of the Borrower to such Guarantor of whatever description, including without limitation, all intercompany receivables of such Guarantor from the Borrower (collectively, the “Junior Claims”) shall be subordinate and junior in right of payment to all Guarantied Obligations. If an Event of Default shall exist, then no Guarantor shall accept any direct or indirect payment (in cash, property or securities, by setoff or otherwise) from the Borrower on account of or in any manner in respect of any Junior Claim until all of the Guarantied Obligations have been indefeasibly paid in full.

Section 14. Avoidance Provisions. It is the intent of each Guarantor, the Agent and the Lenders that in any Proceeding, such Guarantor’s maximum obligation hereunder shall equal, but not exceed, the maximum amount which would not otherwise cause the obligations of such Guarantor hereunder (or any other obligations of such Guarantor to the Agent and the Lenders) to be avoidable or unenforceable against such Guarantor in such Proceeding as a result of Applicable Law, including without limitation, (a) Section 548 of the Bankruptcy Code of 1978, as amended (the “Bankruptcy Code”) and (b) any state fraudulent transfer or fraudulent conveyance act or statute applied in such Proceeding, whether by virtue of Section 544 of the Bankruptcy Code or otherwise. The Applicable Laws under which the possible avoidance or unenforceability of the obligations of such Guarantor hereunder (or any other obligations of such Guarantor to the Agent and the Lenders) shall be determined in any such Proceeding are referred to as the “Avoidance Provisions”. Accordingly, to the extent that the obligations of any Guarantor hereunder would otherwise be subject to avoidance under the Avoidance Provisions, the maximum Guarantied Obligations for which such Guarantor shall be liable hereunder shall be reduced to that amount which, as of the time any of the Guarantied Obligations are deemed to

H-5

have been incurred under the Avoidance Provisions, would not cause the obligations of such Guarantor hereunder (or any other obligations of such Guarantor to the Agent and the Lenders), to be subject to avoidance under the Avoidance Provisions. This Section is intended solely to preserve the rights of the Agent and the Lenders hereunder to the maximum extent that would not cause the obligations of any Guarantor hereunder to be subject to avoidance under the Avoidance Provisions, and no Guarantor or any other Person shall have any right or claim under this Section as against the Agent and the Lenders that would not otherwise be available to such Person under the Avoidance Provisions.

Section 15. Information. Each Guarantor assumes all responsibility for being and keeping itself informed of the financial condition of the Borrower and the other Guarantors, and of all other circumstances bearing upon the risk of nonpayment of any of the Guarantied Obligations and the nature, scope and extent of the risks that such Guarantor assumes and incurs hereunder, and agrees that none of the Agent and the Lenders shall have any duty whatsoever to advise any Guarantor of information regarding such circumstances or risks.

Section 16. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS EXECUTED, AND TO BE FULLY PERFORMED, IN SUCH STATE.

SECTION 17. WAIVER OF JURY TRIAL.

(a) EACH PARTY HERETO ACKNOWLEDGES THAT ANY DISPUTE OR CONTROVERSY BETWEEN OR AMONG ANY GUARANTOR, THE AGENT OR ANY OF THE LENDERS WOULD BE BASED ON DIFFICULT AND COMPLEX ISSUES OF LAW AND FACT AND WOULD RESULT IN DELAY AND EXPENSE TO THE PARTIES. ACCORDINGLY, TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE LENDERS, THE AGENT AND EACH GUARANTOR HEREBY WAIVES ITS RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING OF ANY KIND OR NATURE IN ANY COURT OR TRIBUNAL IN WHICH AN ACTION MAY BE COMMENCED BY OR AGAINST ANY PARTY HERETO ARISING OUT OF THIS GUARANTY OR ANY OTHER LOAN DOCUMENT OR BY REASON OF ANY OTHER SUIT, CAUSE OF ACTION OR DISPUTE WHATSOEVER BETWEEN OR AMONG ANY GUARANTOR, THE AGENT OR ANY OF THE LENDERS OF ANY KIND OR NATURE RELATING TO ANY OF THE LOAN DOCUMENTS.

(b) EACH OF THE GUARANTORS, THE AGENT AND EACH LENDER HEREBY AGREES THAT THE FEDERAL DISTRICT COURT LOCATED IN THE SOUTHERN DISTRICT OF NEW YORK OR, ANY STATE COURT LOCATED IN THE BOROUGH OF MANHATTAN, NEW YORK, NEW YORK, SHALL HAVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN OR AMONG ANY GUARANTOR, THE AGENT OR ANY OF THE LENDERS, PERTAINING DIRECTLY OR INDIRECTLY TO THIS GUARANTY OR ANY OTHER LOAN DOCUMENT OR TO ANY MATTER ARISING HEREFROM OR THEREFROM. EACH GUARANTOR AND EACH OF THE LENDERS EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH

H-6

JURISDICTION IN ANY ACTION OR PROCEEDING COMMENCED IN SUCH COURTS WITH RESPECT TO SUCH CLAIMS OR DISPUTES. EACH PARTY FURTHER WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH ACTION OR PROCEEDING IN ANY SUCH COURT OR THAT SUCH ACTION OR PROCEEDING WAS BROUGHT IN AN INCONVENIENT FORUM AND EACH AGREES NOT TO PLEAD OR CLAIM THE SAME. THE CHOICE OF FORUM SET FORTH IN THIS SECTION SHALL NOT BE DEEMED TO PRECLUDE THE BRINGING OF ANY ACTION BY THE AGENT OR ANY LENDER OR THE ENFORCEMENT BY THE AGENT OR ANY LENDER OF ANY JUDGMENT OBTAINED IN SUCH FORUM IN ANY OTHER APPROPRIATE JURISDICTION.

(c) THE PROVISIONS OF THIS SECTION HAVE BEEN CONSIDERED BY EACH PARTY WITH THE ADVICE OF COUNSEL AND WITH A FULL UNDERSTANDING OF THE LEGAL CONSEQUENCES THEREOF, AND SHALL SURVIVE THE PAYMENT OF THE LOANS AND ALL OTHER AMOUNTS PAYABLE HEREUNDER OR UNDER THE OTHER LOAN DOCUMENTS, THE TERMINATION OR EXPIRATION OF ALL LETTERS OF CREDIT AND THE TERMINATION OF THIS GUARANTY.

Section 18. Loan Accounts. The Agent and each Lender may maintain books and accounts setting forth the amounts of principal, interest and other sums paid and payable with respect to the Guarantied Obligations, and in the case of any dispute relating to any of the outstanding amount, payment or receipt of any of the Guarantied Obligations or otherwise, the entries in such books and accounts shall be deemed conclusive evidence of the amounts and other matters set forth herein, absent manifest error. The failure of the Agent or any Lender to maintain such books and accounts shall not in any way relieve or discharge any Guarantor of any of its obligations hereunder.

Section 19. Waiver of Remedies. No delay or failure on the part of the Agent or any Lender in the exercise of any right or remedy it may have against any Guarantor hereunder or otherwise shall operate as a waiver thereof, and no single or partial exercise by the Agent or any Lender of any such right or remedy shall preclude any other or further exercise thereof or the exercise of any other such right or remedy.

Section 20. Termination. This Guaranty shall remain in full force and effect until indefeasible payment in full of the Guarantied Obligations and the other Obligations and the termination or cancellation of the Term Loan Agreement in accordance with its terms.

Section 21. Successors and Assigns. Each reference herein to the Agent or the Lenders shall be deemed to include such Person’s respective successors and assigns (including, but not limited to, any holder of the Guarantied Obligations) in whose favor the provisions of this Guaranty also shall inure, and each reference herein to each Guarantor shall be deemed to include such Guarantor’s successors and assigns, upon whom this Guaranty also shall be binding. The Lenders may, in accordance with the applicable provisions of the Term Loan Agreement, assign, transfer or sell any Guarantied Obligation, or grant or sell participations in any Guarantied Obligations, to any Person without the consent of, or notice to, any Guarantor

H-7

and without releasing, discharging or modifying any Guarantor’s obligations hereunder. Subject to Section 12.8. of the Term Loan Agreement, each Guarantor hereby consents to the delivery by the Agent or any Lender to any Eligible Assignee or Participant (or any prospective Eligible Assignee or Participant) of any financial or other information regarding the Borrower or any Guarantor. No Guarantor may assign or transfer its obligations hereunder to any Person without the prior written consent of all Lenders and any such assignment or other transfer to which all of the Lenders have not so consented shall be null and void.

Section 22. JOINT AND SEVERAL OBLIGATIONS. THE OBLIGATIONS OF THE GUARANTORS HEREUNDER SHALL BE JOINT AND SEVERAL, AND ACCORDINGLY, EACH GUARANTOR CONFIRMS THAT IT IS LIABLE FOR THE FULL AMOUNT OF THE “GUARANTIED OBLIGATIONS” AND ALL OF THE OBLIGATIONS AND LIABILITIES OF EACH OF THE OTHER GUARANTORS HEREUNDER.

Section 23. Amendments. This Guaranty may not be amended except in writing signed by the Requisite Lenders (or all of the Lenders if required under the terms of the Term Loan Agreement), the Agent and each Guarantor.

Section 24. Payments. All payments to be made by any Guarantor pursuant to this Guaranty shall be made in Dollars, in immediately available funds to the Agent at the Principal Office, not later than 2:00 p.m. on the date of demand therefor.

Section 25. Notices. All notices, requests and other communications hereunder shall be in writing (including facsimile transmission or similar writing) and shall be given (a) to each Guarantor at its address set forth below its signature hereto, (b) to the Agent or any Lender at its respective address for notices provided for in the Term Loan Agreement, or (c) as to each such party at such other address as such party shall designate in a written notice to the other parties. Each such notice, request or other communication shall be effective (i) if mailed, when received or when receipt is refused; (ii) if telecopied, when transmitted; or (iii) if hand delivered, when delivered; provided, however, that any notice of a change of address for notices shall not be effective until received.

Section 26. Severability. In case any provision of this Guaranty shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 27. Headings. Section headings used in this Guaranty are for convenience only and shall not affect the construction of this Guaranty.

Section 28. Limitation of Liability. Neither the Agent nor any Lender, nor any Affiliate, officer, director, employee, attorney, or agent of the Agent or any Lender, shall have any liability with respect to, and each Guarantor hereby waives, releases, and agrees not to sue any of them upon, any claim for any special, indirect, incidental, or consequential damages suffered or incurred by a Guarantor in connection with, arising out of, or in any way related to, this Guaranty or any of the other Loan Documents, or any of the transactions contemplated by this Guaranty, the Term Loan Agreement or any of the other Loan Documents. Each Guarantor hereby waives,

H-8

releases, and agrees not to sue the Agent or any Lender or any of the Agent’s or any Lender’s Affiliates, officers, directors, employees, attorneys, or agents for punitive damages in respect of any claim in connection with, arising out of, or in any way related to, this Guaranty, the Term Loan Agreement or any of the other Loan Documents, or any of the transactions contemplated by Term Loan Agreement or financed thereby.
