Section 2.05 Interest Elections.

(a) Each Revolving Loan initially shall be of the Type specified in the applicable Revolving Loan Request and, in the case of a Eurodollar Loan, shall have an initial Interest Period as specified in such Revolving Loan Request.

Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Lender of a written Interest Election Request signed by a Financial Officer of the Borrower.

(c) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02:

(d) If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Loan prior to the end of the Interest Period applicable thereto, then, unless such Revolving Loan is repaid as provided herein, at the end of such Interest Period such Revolving Loan shall be continued as a Eurodollar Loan with an Interest Period of one month’s duration. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Lender so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Revolving Loan may be converted to or continued as a Eurodollar Loan and (ii) unless repaid, each Eurodollar Loan shall be converted to an ABR Loan at the end of the Interest Period applicable thereto.

Any termination or reduction of the Commitment shall be permanent.

(c) The entries made in the accounts maintained pursuant to paragraph (b) of this Section shall be conclusive evidence (absent manifest error) of the existence and amounts of the obligations recorded therein; provided that the failure of the Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Credit Agreement.

(d) The Lender may request that Loans made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to the Lender a promissory note payable to the order of the Lender and in a form approved by the Lender and the Borrower.

Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Loan or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitment as contemplated by Section 2.06, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.06. Each partial prepayment of any Loan shall be in an amount that would be permitted in the case of an advance of a Loan of the same Type as provided in Section 2.02. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.10.

Section 2.09 Fees.

(a) The Borrower agrees to pay to the Lender a facility fee, which shall accrue at the Applicable Rate on the daily amount of the Commitment (whether used or unused) during the period from and including the Closing Date to but excluding the date on which such Commitment terminates. Accrued facility fees shall be payable in arrears on the last day of March, June, September and December of each year and on the date on which the Commitments terminate, commencing on the first such date to occur after the date hereof; provided that any facility fees accruing after the date on which the Commitments terminate shall be payable on demand. All facility fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(b) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Lender. Fees paid shall not be refundable under any circumstances.

(b) Each Eurodollar Loan shall bear interest at a rate per annum equal to the LIBO Rate for the Interest Period in effect for such Loan plus 0.185%.

(c) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due (following the expiration of any grace period specified in Article VI), whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided above or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided above.

(d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan; provided that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Loan prior to the end of the Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment, (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefore, accrued interest on such Loan shall be payable on the effective date of such conversion and (iv) all accrued interest shall be payable upon termination of the Commitment.

(e) All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate or LIBO Rate shall be determined by the Lender, and such determination shall be conclusive absent manifest error.

(f) If the Lender shall be required under the regulations of the Board to maintain reserves with respect to liabilities or assets consisting of, or including, Eurocurrency Liabilities (as defined in Regulation D of the Board), the Borrower shall pay to the Lender, additional interest on the unpaid principal amount of each Eurodollar Loan made to the Borrower by the Lender, from the later of the date of such Loan or the date the Lender was required to maintain such reserves until such Loan is paid in full, at an interest rate per annum equal to the remainder obtained by subtracting (i) the LIBO Rate for the Interest Period for such Loan from (ii) the rate obtained by multiplying LIBO Rate as referred to in clause (i) above by the Statutory Reserve Rate applicable to the Lender for such Interest Period. Such additional interest shall be determined by the Lender and notified to the Borrower not later than five Business Days before the next Interest Payment Date for such Eurodollar Loan.

Section 2.11 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Loan:

(a) the Lender reasonably determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the LIBO Rate for such Interest Period; or

(b) the Lender, in its reasonable judgment believes that the LIBO Rate for such Interest Period will not adequately and fairly reflect the cost to the Lender of making or maintaining its Revolving Loan for such Interest Period;

then the Lender shall give notice thereof to the Borrower by telephone or telecopy as promptly as practicable thereafter and, until the Lender notifies the Borrower that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Revolving Loan to, or continuation of any Revolving Loan as, a Eurodollar Loan shall be ineffective, and (ii) if any Revolving Loan Request requests a Eurodollar Loan, such Revolving Loan shall be made as an ABR Loan.

Section 2.12 Increased Costs.

(a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by the Lender (other than any reserves included in the Statutory Reserve Rate); or

(ii) impose on the Lender or the London interbank market any other condition affecting this Credit Agreement or Eurodollar Loans;

and the result of any of the foregoing shall be to increase the cost (except with respect to Excluded Taxes) to the Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to increase the cost (except with respect to Excluded Taxes) by the Lender (whether of principal, interest or otherwise) by an amount deemed by the Lender to be material, then the Borrower will pay to the Lender, such additional amount or amounts as will compensate the Lender for such additional costs incurred or reduction suffered.

(b) If the Lender reasonably determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on the Lender’s capital or on the capital of the Lender’s holding company, if any, as a consequence of this Credit Agreement or the Loans made by the Lender, to a level below that which the Lender or the Lender’s holding company could have achieved but for such Change in Law (taking into consideration the Lender’s policies and the policies of the Lender’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to the Lender, such additional amount or amounts as will compensate the Lender or the Lender’s holding company for any such reduction suffered.

(c) A certificate of the Lender setting forth the amount or amounts necessary to compensate the Lender or its holding company, as specified in paragraph (a) or (b) of this Section and the method of calculating such amounts, in reasonable detail, shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay the Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Failure or delay on the part of the Lender to demand compensation pursuant to this Section shall not constitute a waiver of the Lender’s right to demand such compensation; provided that the Borrower shall not be required to compensate the Lender pursuant to this Section for any increased costs or reductions incurred more than six months prior to the date that the Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of the Lender’s intention to claim compensation therefore; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the six-month period referred to above shall be extended to include the period of retroactive effect thereof.

Section 2.13 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice is permitted to be revocable under Section 2.08(b) if such notice is revoked in accordance herewith two Business Days or less before the specified effective date), (d) the assignment of any Eurodollar Loan, then, in any such event, the Borrower shall compensate the Lender for the loss, cost and expense (but not loss of profit) attributable to such event. In the case of a Eurodollar Loan, the loss to the Lender attributable to any such event shall be deemed to include an amount reasonably determined by the Lender to be equal to the excess, if any, of (i) the amount of interest that the Lender would pay for a deposit equal to the principal amount of such Loan for the period from the date of such payment, conversion, failure or assignment to the last day of the then current Interest Period for such Loan (or, in the case of a failure to borrow, convert or continue, the duration of the Interest Period that would have resulted from such borrowing, conversion or continuation) if the interest rate payable on such deposit were equal to the LIBO Rate for such Interest Period, over (ii) the amount of interest that the Lender would earn on such principal amount for such period if the Lender were to invest such principal amount for such period at the interest rate that would be bid by the Lender (or an affiliate of the Lender) for dollar deposits from other banks in the eurodollar market at the commencement of such period. A certificate of the Lender setting forth any amount or amounts that the Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay the Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

Section 2.14 Taxes.

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

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

(c) The Borrower shall indemnify the Lender, within 10 days after written demand therefore, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the Lender and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by the Lender shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Lender the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Lender.

(e) If the Lender claims any additional amounts payable pursuant to this Section 2.14, it agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to select or change the jurisdiction of its applicable lending office if the making of such a selection or change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of the Lender, be otherwise disadvantageous to the Lender.

(f) If the Lender obtains a refund of any Tax for which payment has been made pursuant to this Section 2.14, which refund in the good faith judgment of the Lender (and without any obligation to disclose its tax records) is allocable to such payment made under this Section 2.14, the amount of such refund (together with any interest received thereon and reduced by reasonable costs incurred in obtaining such refund) promptly shall be paid to the Borrower to the extent payment has been made in full by the Borrower pursuant to this Section 2.14.

Section 2.15 Payments Generally. The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, or under Section 2.12, 2.13 or 2.14, or otherwise) prior to 1:00 P.M. (New York City time), on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Lender, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Lender at its offices at 227 West Monroe Street, Suite 2300, Chicago, Illinois 60606, except that payments pursuant to Sections 2.12, 2.13, 2.14 and 7.03 shall be made directly to the Persons entitled thereto. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in dollars.

Section 2.16 Extension of Maturity Date.

(a) At least 45 days but not more than 60 days prior to the first anniversary of the Closing Date, the Borrower, by written notice to the Lender, may request an extension of the Maturity Date in effect at such time by one year from its then scheduled expiration. The Lender shall in its sole discretion, not later than 20 days prior to such anniversary date, notify the Borrower in writing as to whether the Lender will consent to such extension.

(b) If the Lender consents in writing to any such request in accordance with subsection (a) of this Section 2.16, the Maturity Date in effect at such time shall, effective as at the applicable anniversary date (the “Extension Date”), be extended for one year; provided that on each Extension Date (x) the representations and warranties in Article III shall be true and correct and (y) no Default shall have occurred and be continuing.

(a) No failure or delay by the Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power.

(b) The Borrower shall indemnify the Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees and disbursements of any outside counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Credit Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of

their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iii) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by the Borrower or any of their respective directors, shareholders or creditors, an Indemnitee or any other Person, and regardless of whether any Indemnitee is a party thereto (all of the foregoing, collectively, the “Indemnified Liabilities”); provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of such Indemnitee.

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

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

Section 7.04 Successors and Assigns.

(a) The provisions of this Credit Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void). Nothing in this Credit Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the Related Parties of the Lender) any legal or equitable right, remedy or claim under or by reason of this Credit Agreement.

(b) The Lender may assign to one or more assignees all or a portion of its rights and obligations under this Credit Agreement; provided that (i) except in the case of an assignment to an Approved Fund with respect thereto, each of the Borrower and the Lender must give their prior written consent to such assignment (which consent shall not be unreasonably withheld), and (ii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Credit Agreement; provided further that any consent of the Borrower otherwise required under this paragraph shall not be required if an Event of Default has occurred and is continuing.

(c) The Lender may, without the consent of the Borrower, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of the Lender’s rights and obligations under this Credit Agreement; provided that (i) the Lender’s obligations under this Credit Agreement shall remain unchanged, (ii) the Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower shall continue to deal solely and directly with the Lender in connection with the Lender’s rights and obligations under this Credit Agreement. Any agreement or instrument pursuant to which the Lender sells such a participation shall provide that the Lender shall retain the sole right to enforce this Credit Agreement and to approve any amendment, modification or waiver of any provision of this Credit Agreement; provided that such agreement or instrument may provide that the Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 7.02(b) that affects such Participant. Subject to paragraph (f) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.12, 2.13 and 2.14 to the same extent as if it were the Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section.

(d) A Participant shall not be entitled to receive any greater payment under Section 2.12 or 2.14 than the 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.

(e) The Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Credit Agreement to secure obligations of the Lender, including any such pledge or assignment to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release the Lender from any of its obligations hereunder or substitute any such assignee for the Lender as a party hereto.

(f) Notwithstanding anything to the contrary contained herein, the Lender may grant to a special purpose funding vehicle (an “SPC”) of the Lender, identified as such in writing from time to time by the Lender to the Borrower, the option to provide to the Borrower all or any part of any Loan that the Lender would otherwise be obligated to make to the Borrower pursuant to Section 2.01; provided that (i) nothing herein shall constitute a commitment to make any Loan by any SPC and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Lender shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment to the same extent, and as if, such Loan were made by the Lender. Each party hereto hereby agrees that no SPC shall be liable for any payment under this Credit Agreement for which the Lender would otherwise be liable, for so long as, and to the extent, the Lender makes such payment. In furtherance of the foregoing, each party hereto hereby agrees that, prior to the date that is one year and one day after the payment in full of all outstanding senior indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings

or similar proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section 7.04 or in Section 7.12, any SPC may (i) with notice to, but without the prior written consent of, the Borrower and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Lender or to any financial institutions providing liquidity and/or credit facilities to or for the account of such SPC to fund the Loans made by such SPC or to support the securities (if any) issued by such SPC to fund such Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of a surety, guarantee or credit or liquidity enhancement to such SPC.

Section 7.05 Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Credit Agreement shall be considered to have been relied upon by the Lender and shall survive the execution and delivery of this Credit Agreement and the making of any Loans, regardless of any investigation made by the Lender on its behalf and notwithstanding that the Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Credit Agreement is outstanding and unpaid and so long as the Commitment have not expired or terminated. The provisions of Sections 2.12, 2.13, 2.14 and 7.03 shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Commitment or the termination of this Credit Agreement or any provision hereof.

Section 7.06 Counterparts; Integration; Effectiveness. This Credit Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Credit Agreement and any separate letter agreements with respect to fees payable to the Lender constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Credit Agreement shall become effective when it shall have been executed by the Lender and when the Lender shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Credit Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Credit Agreement.

Section 7.07 Severability. Any provision of this Credit Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

Section 7.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, the Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by the Lender to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Credit Agreement held by the Lender, irrespective of whether or not the Lender shall have made any demand under this Credit Agreement and although such obligations may be unmatured. The rights of the Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which the Lender may have.

Section 7.09 Governing Law; Jurisdiction; Consent to Service of Process.

(a) This Credit Agreement shall be construed in accordance with and governed by the law of the State of New York.

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

(c) The Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Credit Agreement in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Credit Agreement irrevocably consents to service of process in the manner provided for notices in Section 7.01. Nothing in this Credit Agreement will affect the right of any party to this Credit Agreement to serve process in any other manner permitted by law.

EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT,

TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

For the purposes of this Section, “Information” means all information received from the Borrower relating to the Borrower or its business, other than any such information that is available to the Lender on a nonconfidential basis prior to disclosure by the Borrower; provided that, in the case of information received from the Borrower after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.
