Section 2.02 Making the Revolving Credit Advances. (a) Each Revolving Credit Borrowing shall be made on notice in the form of Exhibit B-1 (a “Notice of Revolving Credit Borrowing”), given not later than 11:00 A.M. (New York City time) (i) on the date of a proposed Revolving Credit Borrowing comprised of Base Rate Advances and (ii) on the third Business Day prior to the date of a proposed Revolving Credit Borrowing comprised of Eurodollar Rate Advances, by the Borrower to the Agent, which shall give to each Bank prompt notice thereof by facsimile. Each Notice of Revolving Credit Borrowing shall be by facsimile, confirmed immediately in writing, in substantially the form of Exhibit B-1, specifying therein the requested (i) date of such Revolving Credit Borrowing, (ii) Type of Revolving Credit Advances comprising such Revolving Credit Borrowing, (iii) aggregate amount of such Revolving Credit Borrowing, and (iv) if such Revolving Credit Borrowing is to be comprised of Eurodollar Rate Advances, the initial Interest Period for each such Revolving Credit Advance. Each Bank shall, before 2:00 p.m. (New York City time) on the date of such Revolving Credit Borrowing, make available for the account of its Applicable Lending Office to the Agent at its address referred to in Section 8.02, in same day funds, such Bank’s ratable portion of such Revolving Credit Borrowing. After the Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Agent will make such funds available to the Borrower at the Agent’s aforesaid address.

(b) Notwithstanding any other provision in this Agreement, at no time shall there be more than ten Revolving Credit Borrowings outstanding; provided that for purposes of the limitation set forth in this sentence, all Revolving Credit Borrowings consisting of Base Rate Advances shall constitute a single Revolving Credit Borrowing.

(c) Each Notice of Revolving Credit Borrowing shall be irrevocable and binding on the Borrower. In the case of any Revolving Credit Borrowing that the related Notice of Revolving Credit Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify each Bank against any loss, cost or expense incurred by such Bank as a result of any failure to fulfill on or before the date specified in such Notice of Revolving Credit Borrowing for such Revolving Credit Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss (excluding loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Bank to fund the Revolving Credit Advance to be made by such Bank as part of such Revolving Credit Borrowing when such Revolving Credit Advance, as a result of such failure, is not made on such date.

(d) Unless the Agent shall have received notice from a Bank prior to the time of any Revolving Credit Borrowing that such Bank will not make available to the Agent such Bank’s ratable portion of such Revolving Credit Borrowing, the Agent may assume that such Bank has made such portion available to the Agent on the date of such Revolving Credit Borrowing in accordance with subsection (a) of this Section 2.02 and the Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Bank shall not have so made such ratable portion available to the Agent, such Bank and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Revolving Credit Advances comprising such Revolving Credit Borrowing and (ii) in the case of such Bank, the Federal Funds Rate. If such Bank shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Bank’s Revolving Credit Advance as part of such Revolving Credit Borrowing for all purposes.

(e) The failure of any Bank to make the Revolving Credit Advance to be made by it as part of any Revolving Credit Borrowing shall not relieve any other Bank of its obligation, if any, hereunder to make its Revolving Credit Advance on the date of such Revolving Credit Borrowing, but no Bank shall be responsible for the failure of any other Bank to make the Revolving Credit Advance to be made by such other Bank on the date of any Revolving Credit Borrowing.

Section 2.03 Issuance of and Drawings and Reimbursement Under Letters of Credit. (a) Request for Issuance. Each Letter of Credit shall be issued upon notice and application, given not later than 11:00 A.M. (New York City time) on at least the third Business Day (or a later day, if acceptable to the relevant Issuing Bank in its sole discretion, but in no event later than the first Business Day) prior to the date of the proposed issuance of such Letter of Credit, by the Borrower to any Issuing Bank: Each of the Borrower and such Issuing Bank shall give to the Agent prompt notice of such notice of issuance by telex or facsimile. Each such notice of issuance of a Letter of Credit (a “Notice of Issuance and Application for Letter of Credit”) shall be by telephone, confirmed immediately in writing, or telex or facsimile (or by electronic communication, if arrangements for doing so have been approved by the applicable Issuing Bank), in the form of Exhibit B-2, specifying therein the requested (A) date of such issuance (which shall be a Business Day), (B) Available Amount of such Letter of Credit, (C) expiration date of such Letter of Credit, (D) name and address of the Subsidiary on behalf of which such issuance of such Letter of Credit is requested, if applicable, (E) name and address of the beneficiary of such Letter of Credit, (F) form of such Letter of Credit and (G) the requested currency of such Letter of Credit, if other than Dollars. If the requested form of such Letter of Credit is acceptable to such Issuing Bank in its reasonable discretion, such Issuing Bank will, upon fulfillment of the applicable conditions set forth in Article III, make such Letter of Credit available to the Borrower at its office referred to in Section 8.02 or as otherwise agreed with the Borrower in connection with such issuance; provided that no Issuing Bank shall be obligated to issue any Letter of Credit in a Foreign Currency, but each Issuing Bank shall be permitted to do so in its sole discretion if requested by the Borrower; provided, further that no Issuing Bank shall be required to issue any Letter of Credit if after giving effect to such issuance the aggregate face amount of all outstanding Letters of Credit issued under this Agreement by such Issuing Bank would exceed its Letter of Credit Commitment, unless such Issuing Bank shall have otherwise agreed. Notwithstanding the foregoing, no Issuing Bank shall issue any Letter of Credit after it has received a notice from the Agent or the Required Banks that a Default or Event of Default has occurred and is continuing, until it receives a subsequent notice from the Agent or the Required Banks that such Default or Event of Default has been cured or waived. Each of the Borrower and each Issuing Bank shall promptly notify the Agent of any issuance of, amendment to, or extension of, any Letter of Credit issued hereunder.

(b) Letter of Credit Reports. Each Issuing Bank shall furnish (A) to the Agent on the first Business Day of each week a written report summarizing issuance and expiration dates of Letters of Credit issued by such Issuing Bank during the previous week and drawings during such week under all Letters of Credit issued by such Issuing Bank, (B) to the Agent on the first Business Day of each month a written report summarizing issuance and expiration dates of Letters of Credit issued by such Issuing Bank during the preceding month and drawings during such month under all Letters of Credit issued by such Issuing Bank and (C) to the Agent on the first Business Day of each calendar quarter a written report setting forth the average daily aggregate Available Amount during the preceding calendar quarter of all Letters of Credit issued by such Issuing Bank. The Agent shall promptly deliver such report to the Banks and the Borrower by the means provided for delivery of Communications pursuant to Section 8.02.

(c) Drawing and Reimbursement. The payment by any Issuing Bank of a draft drawn under any Letter of Credit shall constitute for all purposes of this Agreement the making by such Issuing Bank of a Letter of Credit Advance, which shall be a Base Rate Advance, in the Dollar Equivalent amount of such draft. Upon the issuance of a Letter of Credit by any Issuing Bank under Section 2.03(a), such Issuing Bank shall be deemed, without further action by any party hereto, to have sold to each Bank, and each Bank shall be deemed, without further action by any party hereto, to have purchased from such Issuing Bank, a participation in such Letter of Credit in an amount for each Bank equal to such Bank’s Pro Rata Share of the Available Amount of such Letter of Credit, effective upon the issuance of such Letter of Credit. In consideration and in furtherance of the foregoing, each Bank hereby absolutely and unconditionally agrees to pay such Bank’s Pro Rata Share of each Letter of Credit Advance made by such Issuing Bank and not reimbursed by the Borrower forthwith on the date due by making available for the account of its Applicable Lending Office to the Agent for the account of such Issuing Bank by deposit to the Agent’s Account, in same day funds, an amount equal to such Bank’s Pro Rata Share of such Letter of Credit Advance. Each Bank acknowledges and agrees that its obligation to acquire participations pursuant to this Section 2.03(c) in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or an Event of Default or the termination of the Commitments, and that each such payment shall be made without any off-set, abatement, withholding or reduction whatsoever. Upon any such participation of a Bank of a portion of a Letter of Credit Advance, such Issuing Bank represents and warrants to such other Bank that such Issuing Bank is the legal and beneficial owner of such interest being assigned by it, free and clear of any liens, but makes no other representation or warranty and assumes no responsibility with respect to such Letter of Credit Advance, the Loan Documents or the Borrower. If and to the extent that any Bank shall not have so made the amount of such Letter of Credit Advance available to the Agent, such Bank agrees to pay to the Agent forthwith on demand such amount together with interest thereon, for each day from the date such Letter of Credit Advance is due until the date such amount is paid to the Agent, at the Federal Funds Rate for its account or the account of such Issuing Bank, as applicable. If such Bank shall pay to the Agent such amount for the account of such Issuing Bank on any Business Day, such amount so paid in respect of principal shall constitute a Letter of Credit Advance made by such Bank on such Business Day for purposes of this Agreement, and the outstanding principal amount of the Letter of Credit Advance made by such Issuing Bank shall be reduced by such amount on such Business Day.

(d) Failure to Make Letter of Credit Advances. The failure of any Bank to make the Letter of Credit Advance to be made by it on the date specified in Section 2.03(c) shall not relieve any other Bank of its obligation hereunder to make its Letter of Credit Advance on such date, but no Bank shall be responsible for the failure of any other Bank to make the Letter of Credit Advance to be made by such other Bank on such date.

Section 2.04 Fees. (a) Commitment Fees. The Borrower agrees to pay to the Agent for the account of each Bank a commitment fee through the Termination Date on the amount of such Bank’s Unused Revolving Credit Commitment, (i) from the date of this Agreement in the case of each Bank listed on the signature pages hereof or (ii) from the effective date specified in the Assignment and Acceptance pursuant to which it became a Bank, payable quarterly in arrears (within three Business Days after receipt from the Agent of an invoice therefore) for each period ending on the last day of each March, June, September and December hereafter, commencing December 31, 2005, and on the Termination Date, at a rate per annum equal to the Applicable Commitment Fee Rate in effect from time to time (the “Commitment Fee”).

(ii) The Borrower shall pay to each Issuing Bank, for its own account, (A) an issuance fee for each Letter of Credit issued by such Issuing Bank in an amount equal to 0.125% of the Available Amount of such Letter of Credit on the date of issuance of such Letter of Credit, payable on such date and (B) such other commissions, fronting fees, transfer fees and other fees and charges in connection with the issuance or administration of each Letter of Credit as the Borrower and Issuing Bank shall agree.

(c) Other Fees. The Borrower agrees to pay to the Agent, the Co-Lead Arrangers, and the Banks such other fees as may be separately agreed to in writing.

Section 2.05 Reduction of Commitments. (a) Optional. The Borrower shall have the right, upon at least three Business Days’ notice to the Agent, to terminate in whole or reduce ratably in part the Unused Revolving Credit Commitments; provided that each partial reduction shall be in the minimum aggregate amount of $10,000,000 and in an integral multiple of $5,000,000. Any termination or reduction of any of the Commitments shall be permanent.

(b) Mandatory. The Borrowing Sublimit shall be automatically and permanently reduced upon any sale, lease, transfer or other disposition of all or substantially all of the G&I Business Unit to a Person other than the Borrower or any Subsidiary of the Borrower to $350,000,000; provided that such reduction shall become effective upon the compliance by the Borrower or such Subsidiary of all terms and conditions specified in Section 5.02(e)(iii).

Such Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by facsimile) of such demand for payment and whether such Issuing Bank has made or will make a Letter of Credit Advance with respect thereto; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse such Issuing Bank and the Banks with respect to any such Letter of Credit Advance.

(ii) The Borrower shall repay to the Agent for the account of each Issuing Bank and each other Bank that has made a Letter of Credit Advance on the earlier of the third Business Day following the date on which such Letter of Credit Advance is made and the Termination Date the outstanding principal amount of each Letter of Credit Advance made by each of them.

If on any date the sum of the aggregate principal amount of Revolving Credit Advances outstanding on such date exceeds the Borrowing Sublimit on such date, the Borrower shall, within three Business Days thereafter, prepay Revolving Credit Advances in an aggregate principal amount sufficient to reduce the sum of the Revolving Credit Advances outstanding on such date to be less than or equal to the Borrowing Sublimit on such date.

Section 2.07 Interest. The Borrower shall pay interest on the unpaid principal amount of each Advance from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum:

(a) During such periods as such Advance is a Base Rate Advance, a rate per annum equal at all times to the Base Rate in effect from time to time plus the Applicable Margin in effect from time to time, payable quarterly in arrears on the last day of each March, June, September and December and on the date such Base Rate Advance shall be Converted or paid in full; provided that upon the occurrence and during the continuance of an Event of Default any amount of principal of a Base Rate Advance due hereunder shall bear interest, payable on demand, at a rate per annum equal at all times to the sum of the rate otherwise payable thereon plus 2%.

The Borrower shall pay to each Bank, so long as such Bank shall be required under regulations of the Federal Reserve Board to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each Advance of such Bank during such periods as such Advance is a Eurodollar Rate Advance, from the date of such Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period then in effect for such Eurodollar Rate Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Bank for such Interest Period, payable on each date on which interest is payable on such Eurodollar Rate Advance. Such additional interest shall be determined by such Bank and notified to the Borrower through the Agent.

Section 2.09 Interest Rate Determination. (a) The Agent shall give prompt notice to the Borrower and the Banks of the applicable interest rate determined by the Agent for purposes of Section 2.07(b).

(b) If the Agent is unable to determine the Eurodollar Rate for any Eurodollar Rate Advances:

(i) the Agent shall forthwith notify the Borrower and the Banks that the interest rate cannot be determined for such Eurodollar Rate Advances,

(ii) each such Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefore, Convert into a Base Rate Advance (or if such Advance is then a Base Rate Advance, will continue as a Base Rate Advance), and

(c) If, with respect to any Eurodollar Rate Advances, the Required Banks notify the Agent (A) that the Eurodollar Rate for any Interest Period for such Advances will not adequately reflect the cost to such Required Banks of making, funding or maintaining their respective Eurodollar Rate Advances for such Interest Period or (B) that Dollar deposits for the relevant amounts and Interest Period for their respective Advances are not available to them in the London interbank market, the Agent shall forthwith so notify the Borrower and the Banks, whereupon

(i) each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefore, Convert into a Base Rate Advance, and

(ii) the obligation of the Banks to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrower and the Banks that the circumstances causing such suspension no longer exist.

(d) If the Borrower shall fail to select the duration of any Interest Period for any Eurodollar Rate Advances in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01, the Agent will forthwith so notify the Borrower and the Banks and such Revolving Credit Advances will automatically, on the last day of the then existing Interest Period therefore, Convert into Base Rate Advances (or if such Advances are then Base Rate Advances, will continue as Base Rate Advances).

(e) On the date on which the aggregate unpaid principal amount of Eurodollar Rate Advances comprising any Borrowing shall be reduced, by payment or prepayment or otherwise, to less than $10,000,000, such Advances shall automatically Convert into Base Rate Advances, and on and after such date the right of the Borrower to Convert such Advances into Eurodollar Rate Advances shall terminate.

(New York City time) on at least the first Business Day prior to the date of prepayment in the case of Base Rate Advances or upon at least three Business Days’ notice to the Agent in the case of Eurodollar Rate Advances, in each case stating the proposed date (which shall be a Business Day) and aggregate principal amount of the prepayment, and if such notice is given the Borrower shall, subject to the terms thereof, prepay the outstanding principal amounts of the Advances comprising part of the same Borrowing in whole or ratably in part, together with accrued interest to the date of such prepayment on the principal amount prepaid; provided, however, that (x) each partial prepayment shall be in an aggregate principal amount not less than $10,000,000 in the case of Eurodollar Rate Advances and $5,000,000 in the case of Base Rate Advances and in integral multiples of $1,000,000, and after giving effect thereto no Borrowing then outstanding shall have a principal amount of less than $5,000,000; and (y) in the case of any such prepayment of a Eurodollar Rate Advance, the Borrower shall be obligated to reimburse the Banks in respect thereof pursuant to Section 8.04(b).

Section 2.11 Payments and Computations. (a) The Borrower shall make each payment hereunder and under the Notes not later than 11:00 A.M. (New York City time) on the day when due in Dollars to the Agent (except that payments under Section 2.08 shall be paid directly to the Bank entitled thereto) at Two Penns Way, Suite 200, New Castle, Delaware 19720, in same day funds. The Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal, interest, Commitment Fees or Letter of Credit Fees ratably (except amounts payable pursuant to Section 2.12 or Section 2.13 and except that any Bank may receive less than its ratable share of interest to the extent Section 8.06 is applicable to it) to the Banks for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Bank to such Bank for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to Section 8.08(c), from and after the effective date specified in such Assignment and Acceptance, the Agent shall make all payments hereunder and under the Notes in respect of the interest assigned thereby to the Bank assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves. At the time of each payment of any principal of or interest on any Borrowing to the Agent, the Borrower shall notify the Agent of the Borrowing to which such payment shall apply. In the absence of such notice the Agent may specify the Borrowing to which such payment shall apply.

(b) All computations of interest based on the Base Rate (except during such times as the Base Rate is determined pursuant to clause (c) of the definition thereof), of Commitment Fees and of Letter of Credit Fees shall be made by the Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate, the Federal Funds Rate or, during such times as the Base Rate is determined pursuant to clause (c) of the definition thereof, the Base Rate shall be made by the Agent, and all computations of interest pursuant to Section 2.08 shall be made by a Bank, on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Agent (or in the case of Section 2.08, by a Bank) of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

(c) Whenever any payment hereunder or under the Notes shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest, Commitment Fees and Letter of Credit Fees, as the case may be; provided, however, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(d) Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Banks hereunder that the Borrower will not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank. If and to the extent that the Borrower shall not have so made such payment in full to the Agent, each Bank shall repay to the Agent forthwith on demand such amount distributed to such Bank together with interest thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Agent, at the Federal Funds Rate.

Section 2.12 Increased Costs and Capital Requirements. (a) If, due to either (i) the introduction of or any change (other than any change by way of imposition or increase of reserve requirements included in the Eurodollar Rate Reserve Percentage) in or in the interpretation of any law or regulation by any Governmental Authority charged with the interpretation or administration thereof or (ii) the compliance with any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law), there shall be any increase in the cost to any Bank of agreeing to make or making, funding or maintaining any Eurodollar Rate Advance or of agreeing to issue or of issuing or maintaining or participating in Letters of Credit or of agreeing to make or of making or maintaining Letter of Credit Advances (excluding, for purposes of this Section 2.12, any such increased costs resulting from (x) Taxes or Other Taxes (as to which Section 2.13 shall govern) and (y) changes in the basis of taxation of overall net income or overall gross income by the United States or by the foreign jurisdiction or state under the laws of which such Bank is organized or has its Applicable Lending Office or any political subdivision thereof), then the Borrower shall from time to time, within 15 days after demand by such Bank (with a copy of such demand to the Agent), pay to the Agent for the account of such Bank additional amounts sufficient to compensate such Bank for such increased cost; provided, however, that the Borrower shall not be required to pay to such Bank any portion of such additional amounts that are incurred more than 90 days prior to any such demand, unless such additional amounts had not been imposed or were not determinable on the date that is 90 days prior to such demand. A certificate setting forth in reasonable detail the amount of such increased cost, submitted to the Borrower and the Agent by such Bank, shall be conclusive and binding for all purposes, absent manifest error.

(b) If following the introduction of or any change in any applicable law or regulation or any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law) any Bank determines that compliance by such Bank with any such law or regulation or guideline or request regarding capital adequacy affects or would affect the amount of capital required or expected to be maintained by such Bank or any Person controlling such Bank and that the amount of such capital is increased by or based upon the existence of such Bank’s commitment to lend or to issue or participate in Letters of Credit hereunder and other commitments of such type or the issuance or maintenance of or participation in Letters of Credit (or similar contingent Obligations), then, within 15 days after demand by such Bank (with a copy of such demand to the Agent), the Borrower shall pay to the Agent for the account of such Bank, from time to time as specified by such Bank, additional amounts sufficient to compensate such Bank or such Person in the light of such circumstances, to the extent that such Bank reasonably determines such increase in capital to be allocable to the existence of such Bank’s commitment to lend or to issue or participate in Letters of Credit hereunder or to the issuance of or participation in any Letters of Credit; provided, however, that the Borrower shall not be required to pay to such Bank any portion of such additional amounts that are incurred more than 90 days prior to any such demand, unless such additional amounts had not been imposed or were not determinable on the date that is 90 days prior to such demand. A certificate setting forth in reasonable detail such amounts submitted to the Borrower and the Agent by such Bank shall be conclusive and binding for all purposes, absent manifest error.

(c) Each Bank shall make reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to select a jurisdiction for its Applicable Lending Office or change the jurisdiction of its Applicable Lending Office, as the case may be, so as to avoid the imposition of any increased costs under this Section 2.12 or to eliminate the amount of any such increased cost which may thereafter accrue; provided that no such selection or change of the jurisdiction for its Applicable Lending Office shall be made if, in the reasonable judgment of such Bank, such selection or change would be disadvantageous to such Bank.

Section 2.13 Taxes. (a) Any and all payments by the Borrower hereunder or under the Notes shall be made, in accordance with Section 2.11, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges and withholdings, and all liabilities with respect thereto, excluding, in the case of each Bank and the Agent, taxes imposed on its overall net income (including branch profits), and franchise taxes imposed on or measured by net income, by the jurisdiction under the laws of which such Bank or the Agent (as the case may be) is organized or any political subdivision thereof and, in the case of each Bank, taxes imposed on its overall net income (including branch profits), and franchise taxes imposed on or measured by net income, by the jurisdiction of such Bank’s Applicable Lending Office or principal executive office or any political subdivision thereof, and all liabilities with respect thereto (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”), except as may otherwise be required by law. If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Note to any Bank or the Agent, (i) the sum payable shall be increased by such amount (an “Additional Amount”) as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.13) such Bank or the Agent (as the case may be) 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 taxation authority or other authority in accordance with applicable law. Any such payment by the Borrower shall be made in the name of the relevant Bank or the Agent (as the case may be).

(b) In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under the Notes or from the execution, delivery or registration of, performing under, or otherwise with respect to, this Agreement or any of the Notes (hereinafter referred to as “Other Taxes”).

(c) The Borrower will indemnify each Bank and the Agent for the full amount of Taxes and Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.13) imposed on or paid by such Bank or the Agent (as the case may be) and any liability (including penalties, interest and reasonable expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. Payments under any indemnification provided for in this Section 2.13(c) shall be made within 30 days from the date such Bank or the Agent (as the case may be) makes written demand therefore describing such Taxes or Other Taxes in reasonable detail.

(d) If the Agent or a Bank reasonably determines that it has finally and irrevocably received a refund in respect of any Taxes or Other Taxes as to which it has been indemnified by the Borrower, or with respect to which the Borrower has paid Additional Amounts, pursuant to this Section 2.13, it shall within 30 days from the date of such receipt pay over such refund to the Borrower (but only to the extent such refund is attributable, as reasonably determined by such Agent or Bank, to such indemnity payments made, or Additional Amounts paid, by the Borrower under this Section 2.13 with respect to the Taxes or Other Taxes giving rise to such refund), net of all reasonable out-of-pocket expenses of the Agent or Bank and without interest (other than interest paid by the relevant taxation authority with respect to such refund); provided, however, that the Borrower, upon the request of the Agent or Bank, agrees to repay the amount paid over to the Borrower (plus penalties, interest or other charges, if any, imposed by the relevant taxation authority in respect of such repayment) to the Agent or Bank in the event the Agent or Bank is required to repay such refund to the applicable taxation authority. Nothing contained in this Section 2.13(d) shall interfere with the right of the Agent or any Bank to arrange its tax affairs in whatever manner it determines appropriate nor oblige the Agent or any Bank to claim any tax credit or to disclose any information relating to its tax affairs or any computations in respect thereof or require the Agent or any Bank to do anything that would prejudice its ability to benefit from any other tax relief to which it may be entitled.

(e) Within 30 days after the date of any payment of Taxes, the Borrower will furnish to the Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing payment thereof (or other evidence of payment reasonably satisfactory to the Agent). In the case of any payment hereunder or under the Notes by or on behalf of the Borrower through an account or branch outside the United States or by or on behalf of the Borrower by a payor that is not a United States person, if the Borrower determines that no Taxes are payable in respect thereof, the Borrower shall furnish, or shall cause such payor to furnish, to the Agent, at such address, an opinion of counsel reasonably acceptable to the Agent stating that such payment is exempt from Taxes imposed by the jurisdiction from which such payment is made. For purposes of this Section 2.13(e) and Section 2.13(f), the terms “United States” and “United States person” shall have the meanings specified in Section 7701 of the Code.

(f) Each Bank organized under the laws of a jurisdiction outside the United States, (i) on or prior to the date of the Initial Extension of Credit in the case of each such Bank listed on the signature pages hereof, (ii) on the date of the Assignment and Acceptance pursuant to which it becomes a Bank, (iii) on or before the date, if any, it changes its Applicable Lending Office, and (iv) from time to time thereafter if reasonably requested in writing by the Borrower or the Agent or promptly upon the obsolescence or invalidity of any form previously delivered by such Bank (but only so long as such Bank remains lawfully able to do so), shall provide the Agent and the Borrower with two original Internal Revenue Service Forms W-8BEN or W-8ECI (or, in the case of a Bank that is entitled to claim exemption from withholding of United States federal income tax under Section 871(h) or 881(c) of the Code, (A) a certificate representing that such Bank is not a “bank” for purposes of Section 881(c) of the Code, is not a 10-percent shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of the Borrower and is not a controlled foreign corporation related to the Borrower (within the meaning of Section 864(d)(4) of the Code) and (B) Internal Revenue Service Form W-8BEN), as appropriate, or any successor or other form prescribed by the Internal Revenue Service, properly completed and duly executed by such Bank, certifying that such Bank is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement or the Notes (or, in the case of a Bank providing the certificate described in clause (A), certifying that such Bank is a foreign corporation, partnership, estate or trust). If the forms provided by a Bank at the time such Bank first becomes a party to this Agreement indicate or require a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Taxes for purposes of this Section 2.13 unless and until such Bank provides the appropriate forms certifying that a lesser rate applies, whereupon withholding tax at such lesser rate only shall be considered excluded from Taxes for periods governed by such forms; provided, however, that if, at the effective date of the Assignment and Acceptance pursuant to which a Bank becomes a party to this Agreement (or the date, if any, a Bank changes its Applicable Lending Office), the Bank assignor (or such Bank) was entitled to payments under subsection (a) of this Section 2.13 in respect of United States withholding tax with respect to interest paid at such date, then, to such extent, the term Taxes shall include (in addition to withholding taxes that may be imposed in the future or other amounts otherwise includable in Taxes, subject to the provisions of this subsection (f)) United States withholding tax, if any, applicable with respect to the Bank assignee (or such Bank) on such date.

(g) For any period with respect to which a Bank has failed to provide the Borrower with the appropriate form described in subsection (f) above (other than if such failure is due to a change in law, or in the interpretation or application thereof by any Governmental Authority charged with the interpretation or application thereof, occurring after the date on which a form originally was required to be provided or if such form otherwise is not required under subsection (f) above), such Bank shall not be entitled to indemnification or payment of an Additional Amount under subsection (a) or (c) of this Section 2.13 with respect to Taxes imposed by the United States to the extent such United States Taxes exceed the United States Taxes that would have been imposed had such form been provided; provided, however, that should a Bank become subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as such Bank shall reasonably request to assist such Bank to recover such Taxes.

(h) Any Bank claiming any indemnity payment or Additional Amounts payable pursuant to this Section 2.13 shall use commercially reasonable efforts (consistent with its generally applicable internal policy and legal and regulatory restrictions) to file any certificate or document reasonably requested in writing by the Borrower or to designate a different Applicable Lending Office following the reasonable request in writing of the Borrower if the making of such a filing or change would avoid the need for or reduce the amount of any such indemnity payment or Additional Amounts that may thereafter accrue and would not, in the sole determination of such Bank, require the disclosure of information that the Bank reasonably considers confidential, or be otherwise disadvantageous to such Bank.

Section 2.14 Sharing of Payments, Etc. If any Bank shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the principal of or interest on the Advances owing to it (except amounts payable pursuant to Sections 2.08, 2.12 or 2.13, and except that any Bank may receive less than its ratable share of interest to the extent Section 8.06 is applicable to it) in excess of its ratable share of payments on account of the principal of or interest on the Advances obtained by all the Banks, such Bank shall forthwith purchase from the other Banks such participations in the Advances owing to them as shall be necessary to cause such purchasing Bank to share the excess payment ratably with each of them, provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Bank, such purchase from each Bank shall be rescinded and such Bank shall repay to the purchasing Bank the purchase price to the extent of such Bank’s ratable share (according to the proportion of (i) the amount of the participation purchased from such Bank as a result of such excess payment to (ii) the total amount of such excess payment) of such recovery together with an amount equal to such Bank’s ratable share (according to the proportion of (i) the amount of such Bank’s required repayment to (ii) the total amount so recovered from the purchasing Bank) of any interest or other amount paid or payable by the purchasing Bank in respect of the total amount so recovered. The Borrower agrees that any Bank so purchasing a participation from another Bank pursuant to this Section 2.14 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Bank were the direct creditor of the Borrower in the amount of such participation.

Section 2.15 Illegality. Notwithstanding any other provision of this Agreement, if any Bank (“Affected Bank”) shall notify the Borrower and the Agent that the introduction of or any change in any law or regulation makes it unlawful, or any central bank or other Governmental Authority asserts that it is unlawful, for any Bank, or its Eurodollar Lending Office, to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder, (i) the obligation of the Affected Bank to make, or to Convert Advances into, Eurodollar Rate Advances shall forthwith be suspended (and any request by the Borrower for a Borrowing comprised of Eurodollar Rate Advances shall, as to each Affected Bank, be deemed a request for a Base Rate Advance to be made on the same day as the Eurodollar Rate Advances of the Banks that are not Affected Banks and such Base Rate Advance shall be considered as part of such Borrowing) until the Affected Bank shall notify the Borrower, the Banks and the Agent that the circumstances causing such suspension no longer exist and (ii) forthwith after such notice from an Affected Bank to the Agent and the Borrower, all Eurodollar Rate Advances of such Affected Bank shall be deemed to be Converted to Base Rate Advances (but will otherwise continue to be considered as a part of the respective Borrowings that they were a part of prior to such Conversion); provided, however, that, before making any such demand, such Bank agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Eurodollar Lending Office if the making of such a designation would allow such Bank or its Eurodollar Lending Office to continue to perform its obligations to make Eurodollar Rate Advances or to continue to fund or maintain Eurodollar Rate Advances and would not, in the judgment of such Bank, be otherwise materially disadvantageous to such Bank. In the event any Bank shall notify the Agent of the occurrence of any circumstance contemplated under this Section 2.15, all payments and prepayments of principal that would otherwise have been applied to repay the Eurodollar Rate Advances that would have been made by such Bank or the Converted Eurodollar Rate Advances shall instead be applied to repay the Base Rate Advances made by such Bank in lieu of such Eurodollar Rate Advances or resulting from the Conversion of such Eurodollar Rate Advances and shall be made at the time that payments on the Eurodollar Rate Advances of the Banks that are not Affected Banks are made. Each Bank that has delivered a notice of illegality pursuant to this Section 2.15 above agrees that it will notify the Borrower as soon as practicable if the conditions giving rise to the illegality cease to exist.

Section 2.16 Conversion of Advances. The Borrower may on any Business Day, upon notice given to the Agent not later than 11:00 A.M. (New York City time) on the third Business Day prior to the date of the proposed Conversion and subject to the provisions of Sections 2.02(b), 2.09 and 2.15, Convert all Advances of one Type comprising the same Borrowing into Advances of the other Type; provided, however, that (i) any Conversion of any Eurodollar Rate Advances into Base Rate Advances shall be made on, and only on, the last day of an Interest Period for such Eurodollar Rate Advances, except as provided in Section 2.15, and (ii) Advances comprising a Borrowing may not be Converted into Eurodollar Rate Advances if the outstanding principal amount of such Borrowing is less than $10,000,000 or if any Event of Default under Section 6.01(a) shall have occurred and be continuing on the date the related notice of Conversion would otherwise be given pursuant to this Section 2.16. Each such notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the Advances to be Converted, and (iii) if such Conversion is into Eurodollar Rate Advances, the duration of the initial Interest Period for each such Advance. Each notice of Conversion shall be irrevocable and binding on the Borrower. If any Event of Default under Section 6.01(a) shall have occurred and be continuing on the third Business Day prior to the last day of any Interest Period for any Eurodollar Rate Advances, the Borrower agrees to Convert all such Advances into Base Rate Advances on the last day of such Interest Period.

Section 2.17 Replacement or Removal of Bank. In the event that any Bank shall claim payment of any increased costs pursuant to Section 2.12 or the Borrower is required to pay any Additional Amounts, Taxes or Other Taxes to or on account of any Bank pursuant to Section 2.13, or exercises its rights under Section 2.15, or if any Bank fails to execute and deliver a consent, amendment or waiver to this Agreement requested by the Borrower by the date specified by the Borrower (or gives the Borrower written notice prior to such date of its intention not to do so) the Borrower shall have the right, if no Default or Event of Default then exists, to (a) replace such Bank with an Eligible Assignee in accordance with Section 8.08(a), (b) and (d) (including execution of an appropriate Assignment and Acceptance); provided that such Eligible Assignee (i) shall unconditionally offer in writing (with a copy to the Agent) to purchase on a date therein specified all of such Bank’s rights hereunder and interest in the Advances owing to such Bank and the Note held by such Bank without recourse at the principal amount of such Note plus interest, Commitment Fees and Letter of Credit Fees accrued thereon to the date of such purchase and (ii) shall execute and deliver to the Agent an Assignment and Acceptance, as assignee, pursuant to which such Eligible Assignee becomes a party hereto with a Commitment equal to that of the Bank being replaced (plus, if such Eligible Assignee is already a Bank, the amount of its Commitment prior to such replacement), provided, further, that no Bank or other Person shall have any obligation to increase its Commitment or otherwise to replace, in whole or in part, any Bank or (b) remove such Bank without replacing it; provided that the Borrower may not remove a Bank pursuant to this clause (b) if the aggregate Commitments of all Banks so removed would exceed $100,000,000. Upon satisfaction of the requirements set forth in the first sentence of this Section 2.17, acceptance of such offer to purchase by the Bank to be replaced, payment to such Bank of the purchase price in immediately available funds by the Eligible Assignee replacing such Bank, execution of such Assignment and Acceptance by such Bank, such Eligible Assignee and the Agent, the payment by the Borrower of all requested costs accruing to the date of purchase which the Borrower is obligated to pay under Section 8.04 and all other amounts owed by the Borrower to such Bank (other than Commitment Fees and Letter of Credit Fees accrued for the account of such Bank and the principal of and interest on the Advances of such Bank purchased by such Eligible Assignee) and notice by the Borrower to the Agent that such payment has been made, such Eligible Assignee shall constitute a “Bank” hereunder with a Commitment as so specified and the Bank being so replaced shall no longer constitute a “Bank” hereunder except that the rights under Sections 2.07, 2.12, 2.13 and 8.04 of the Bank being so replaced shall continue with respect to events and occurrences before or concurrently with its ceasing to be a “Bank” hereunder. If, however, (x) a Bank accepts such an offer and such Eligible Assignee fails to purchase such rights and interest on such specified date in accordance with the terms of such offer or such Eligible Assignee or the Agent fails to execute the relevant Assignment and Acceptance, the Borrower shall continue to be obligated to pay the increased costs to such Bank pursuant to Section 2.12 or the additional amounts pursuant to Section 2.13, as the case may be, or (y) the Bank proposed to be replaced fails to accept such purchase offer or to execute the relevant Assignment and Acceptance, the Borrower shall not be obligated to pay to such Bank such increased costs or additional amounts incurred or accrued from and after the date of such purchase offer.

Section 2.18 Evidence of Indebtedness. Each Bank shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Bank resulting from each Advance owing to such Bank from time to time, including the amounts of principal and interest payable and paid to such Bank from time to time hereunder. The Borrower agrees that upon notice by any Bank to the Borrower (with a copy of such notice to the Agent) to the effect that a promissory note or other evidence of indebtedness is required or appropriate in order for such Bank to evidence (whether for purposes of pledge, enforcement or otherwise) the Advances owing to, or to be made by, such Bank, the Borrower shall promptly execute and deliver to such Bank, with a copy to the Agent, a Note in substantially the form of Exhibit A hereto, payable to the order of such Bank in a principal amount equal to the Revolving Credit Commitment of such Bank. All references to Notes in the Loan Documents shall mean Notes, if any, to the extent issued hereunder.

Section 2.19 Increase in the Aggregate Revolving Credit Commitments; Increase in Letter of Credit Commitment. (a) The Borrower may, at any time and from time to time prior to the Termination Date, by notice to the Agent, request that the aggregate amount of the Revolving Credit Commitments to be used solely for the issuance of Letters of Credit be increased by an amount of not less than $50,000,000 and in integral multiples of $10,000,000 in excess thereof (each a “Commitment Increase”) to be effective as of a date that is at least 90 days prior to the scheduled Maturity Date (the “Increase Date”) as specified in the related notice to the Agent; provided, however, that (i) in no event shall the aggregate amount of the Revolving Credit Commitments at any time exceed $1,100,000,000 and (ii) on the date of any request by the Borrower for a Commitment Increase and on the related Increase Date, the applicable conditions set forth in Section 3.02 shall be satisfied. Any Commitment Increase shall not increase the Borrowing Sublimit.

(b) The Agent shall promptly notify the Banks of a request by the Borrower for a Commitment Increase, which notice shall include (i) the proposed amount of such requested Commitment Increase, (ii) the proposed Increase Date and (iii) the date by which Banks wishing to participate in the Commitment Increase must commit to an increase in the amount of their respective Revolving Credit Commitments (the “Commitment Date”). Each Bank that is willing to participate in such requested Commitment Increase (each an “Increasing Lender”) shall, in its sole discretion, give written notice to the Agent on or prior to the Commitment Date of the amount by which it is willing to increase its Revolving Credit Commitment. If the Banks notify the Agent that they are willing to increase the amount of their respective Revolving Credit Commitments by an aggregate amount that exceeds the amount of the requested Commitment Increase, the requested Commitment Increase shall be allocated among the Banks willing to participate therein in such amounts as are agreed between the Borrower and the Agent.

(c) Promptly following each Commitment Date, the Agent shall notify the Borrower as to the amount, if any, by which the Banks are willing to participate in the requested Commitment Increase. If the aggregate amount by which the Banks are willing to participate in any requested Commitment Increase on any such Commitment Date is less than the requested Commitment Increase, then the Borrower may extend offers to one or more Eligible Assignees to participate in any portion of the requested Commitment Increase that has not been committed to by the Banks as of the applicable Commitment Date; provided, however, that the Revolving Credit Commitment of each such Eligible Assignee shall be in an amount of $10,000,000 or an integral multiple of $1,000,000 in excess thereof. The Borrower, at its discretion, may withdraw its request for a Commitment Increase at any time prior to the Increase Date.

(d) On each Increase Date, each Eligible Assignee that accepts an offer to participate in a requested Commitment Increase in accordance with Section 2.19(c) (each such Eligible Assignee, an “Assuming Lender”) shall become a Bank party to this Agreement as of such Increase Date and the Revolving Credit Commitment of each Increasing Lender for such requested Commitment Increase shall be so increased by such amount (or by the amount allocated to such Bank pursuant to the last sentence of Section 2.19(b)) as of such Increase Date; provided, however, that the Agent shall have received on or before such Increase Date the following, each dated such date:

(i) an assumption agreement from each Assuming Lender, if any, in form and substance satisfactory to the Borrower and

the Agent (each an “Assumption Agreement”), duly executed by such Eligible Assignee, the Agent and the Borrower; and

(ii) confirmation from each Increasing Lender of the increase in the amount of its Commitment in a writing satisfactory to

the Borrower and the Agent.

(e) At any time, any Issuing Bank and the Borrower may agree to increase the Letter of Credit Commitment of such Issuing Bank with the consent of the Agent. The Agent shall adjust the Letter of Credit Commitments of the existing Issuing Banks to the extent of the increase in such Issuing Bank’s Letter of Credit Commitment as the affected Issuing Banks and the Agent shall agree in writing.

(f) Any Bank may become an Issuing Bank by written agreement between such Bank and the Borrower, subject to notice to and the consent of the Agent. The Agent shall notify the Banks of the designation of any additional Issuing Bank hereunder and shall adjust the Letter of Credit Commitments of the existing Issuing Banks to the extent of such new Issuing Bank’s Letter of Credit Commitment as the affected Issuing Banks and the Agent shall agree in writing.

On each Increase Date, upon fulfillment of the conditions set forth in Section 2.19(d), at the time any Issuing Bank and the Borrower agree to increase the Letter of Credit Commitment of such Issuing Bank pursuant to Section 2.19(e) and at the time any Bank becomes an Issuing Bank pursuant to Section 2.19(f), the Agent shall notify the Banks (including, without limitation, each Assuming Lender, if applicable) and the Borrower, on or before 1:00 P.M. (New York City time), by telecopier, of the occurrence of the Commitment Increase to be effected on such Increase Date, the Letter of Credit Commitment increase and the effective date thereof or any Bank becoming an Issuing Bank and the effective date thereof, as the case may be, and, in each case, shall record in the Register the relevant information with respect to each Increasing Lender, each Assuming Lender, each Letter of Credit Commitment increase or adjustment, as applicable, and any addition of an Issuing Bank, as applicable, on such date. On the last day of the Interest Period in effect on any Increase Date, the Borrower shall make such Borrowings and prepayments as shall be necessary to cause the outstanding Advances to be ratable with the revised Commitments resulting from any non-ratable increase in the Commitments under this Section 2.19.

If no successor Agent shall have been so appointed by the Required Banks (and, if not a Bank, approved by the Borrower), and shall have accepted such appointment, within 30 days after the retiring Agent’s giving of notice of resignation or the Required Banks’ removal of the retiring Agent, then the retiring Agent may, on behalf of the Banks, appoint a successor Agent, which shall be a commercial bank organized or licensed under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $500,000,000.

Each Bank agrees promptly to notify the Borrower after any such set-off and application made by such Bank, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Bank under this Section are in addition to other rights and remedies (including, without limitation, other rights of setoff) which such Bank may have.

Section 8.06 Limitation and Adjustment of Interest. (a) Notwithstanding anything to the contrary set forth herein, in any other Loan Document or in any other document or instrument, no provision of any of the Loan Documents or any other instrument or document furnished pursuant hereto or in connection herewith is intended or shall be construed to require the payment or permit the collection of interest in excess of the maximum non-usurious rate permitted by applicable law. Accordingly, if the transactions with any Bank contemplated hereby would be usurious under applicable law, if any, then, in that event, notwithstanding anything to the contrary in any Note payable to such Bank, this Agreement or any other document or instrument, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under applicable law that is contracted for, taken, reserved, charged or received by such Bank under any Note payable to such Bank, this Agreement or any other document or instrument shall under no circumstances exceed the maximum amount allowed by such applicable law, and any excess shall be canceled automatically and, if theretofore paid, shall, at the option of such Bank, be credited by such Bank on the principal amount of the indebtedness owed to such Bank by the Borrower or refunded by such Bank to the Borrower, and (ii) in the event that the maturity of any Note payable to such Bank is accelerated or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to such Bank may never include more than the maximum amount allowed by such applicable law and excess interest, if any, to such Bank provided for in this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall, at the option of such Bank, be credited by such Bank on the principal amount of the indebtedness owed to such Bank by the Borrower or refunded by such Bank to the Borrower. In determining whether or not the interest contracted for, taken, reserved, charged or received by any Bank exceeds the maximum non-usurious rate permitted by applicable law, such determination shall be made, to the extent that doing so does not result in a violation of applicable law, by amortizing, prorating, allocating and spreading, in equal parts during the period of the full stated term of the loans hereunder, all interest at any time contracted for, taken, charged, received or reserved by such Bank in connection with such loans.

(b) In the event that at any time the interest rate applicable to any Advance made by any Bank would exceed the maximum non-usurious rate allowed by applicable law, the rate of interest to accrue on the Advances by such Bank shall be limited to the maximum non-usurious rate allowed by applicable law, but shall accrue, to the extent permitted by law, on the principal amount of the Advances made by such Bank from time to time outstanding, if any, at the maximum non-usurious rate allowed by applicable law until the total amount of interest accrued on the Advances made by such Bank equals the amount of interest which would have accrued if the interest rates applicable to the Advances pursuant to Article II had at all times been in effect. In the event that upon the final payment of the Advances made by any Bank and termination of the Commitment of such Bank, the total amount of interest paid to such Bank hereunder and under the Notes is less than the total amount of interest which would have accrued if the interest rates applicable to such Advances pursuant to Article II had at all times been in effect, then the Borrower agrees to pay to such Bank, to the extent permitted by law, an amount equal to the excess of (a) the lesser of (i) the amount of interest which would have accrued on such Advances if the maximum non-usurious rate allowed by applicable law had at all times been in effect or (ii) the amount of interest which would have accrued on such Advances if the interest rates applicable to such Advances pursuant to Article II had at all times been in effect over (b) the amount of interest otherwise accrued on such Advances in accordance with this Agreement.

Section 8.07 Binding Effect. This Agreement shall become effective as provided in Section 3.01 hereof and thereafter shall be binding upon and inure to the benefit of the Borrower and the Agent and each Bank and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights or obligations hereunder or under any other Loan Document or any interest herein or therein without the prior written consent of all of the Banks.

Section 8.08 Assignments and Participations. (a) Each Bank may assign to one or more banks or other entities all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Advances owing to it and the Notes held by it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of all rights and obligations under this Agreement, (ii) except in the case of an assignment of all of a Bank’s rights and obligations under this Agreement, the amount of the Commitment of the assigning Bank being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $5,000,000, (iii) each such assignment shall be to an Eligible Assignee, and (iv) the parties to each such assignment shall execute and deliver to the Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with the Notes subject to such assignment and a processing and recordation fee of $3,000. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, (x) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Bank hereunder and (y) the Bank assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of an assigning Bank’s rights and obligations under this Agreement, such Bank shall cease to be a party hereto).

(b) By executing and delivering an Assignment and Acceptance, the Bank assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, such assigning Bank makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with any Loan Document or any other instrument or document furnished pursuant hereto or in connection herewith or the execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan Document or any other instrument or document furnished pursuant hereto or in connection herewith; (ii) such assigning Bank makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or any other Person or the performance or observance by the Borrower or any other Person of any of its respective obligations under any Loan Document or any other instrument or document furnished pursuant hereto or in connection herewith; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the most recent financial statements delivered pursuant to Section 5.01(d) and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the Agent, such assigning Bank or any other Bank and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement, any of the other Loan Documents or any other instrument or document; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Agent to take such action as Agent on its behalf and to exercise such powers and discretion under the Loan Documents as are delegated to the Agent by the terms hereof or thereof, together with such powers and discretion as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Bank.

(c) The Agent shall maintain at its address referred to in Section 8.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Banks and the Commitment of, and the principal amount of the Revolving Credit Advances owing to, each Bank from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Agent and the Banks may treat each Person whose name is recorded in the Register as a Bank hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Bank at any reasonable time and from time to time upon reasonable prior notice.

(d) Upon its receipt of an Assignment and Acceptance executed by an assigning Bank and an assignee representing that it is an Eligible Assignee, together with the Notes, if any, subject to such assignment, the Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit E, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower. Within five Business Days after its receipt of such notice, the Borrower shall execute and deliver to the Agent in exchange for the surrendered Notes, if any, a new Note (if requested by the assignee) payable to the order of such Eligible Assignee in an amount equal to the Commitment assumed by it pursuant to such Assignment and Acceptance and, if the assigning Bank has retained a Commitment hereunder, a new Note payable to the order of the assigning Bank in an amount equal to the Commitment retained by it hereunder (such new Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Notes, shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in substantially the form of Exhibit A).

(e) Each Bank may sell participations to one or more banks or other entities (other than the Borrower or any of its Affiliates) in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment, the Advances owing to it and the Notes held by it); provided, however, that (i) such Bank’s obligations under this Agreement (including, without limitation, its Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Bank shall remain the holder of any such Notes for all purposes of this Agreement, (iv) the Borrower, the Agent and the other Banks shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this Agreement, and (v) the terms of any such participation shall not restrict such Bank’s ability to make any amendment or waiver of this Agreement or any Note or such Bank’s ability to consent to any departure by the Borrower therefrom without the approval of the participant, except that the approval of the participant may be required to the extent that such amendment, waiver or consent would reduce the principal of, or interest on, the Notes or any fees or other amounts payable hereunder, in each case to the extent subject to such participation, or postpone any date fixed for any payment of principal of, or interest on, the Notes or any fees or other amounts payable hereunder, in each case to the extent subject to such participation.

(f) Each Issuing Bank may assign to an Eligible Assignee all of its rights and obligations under the undrawn portion of its Letter of Credit Commitment at any time; provided, however, that (i) each such assignment shall be to an Eligible Assignee and (ii) the parties to each such assignment shall execute and deliver to the Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with a processing and recordation fee of $3,000.

(g) Any Bank may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 8.08, disclose to the assignee or participant or proposed assignee or participant, any information relating to the Borrower or any of its Subsidiaries furnished to such Bank by or on behalf of the Borrower or any of its Subsidiaries; provided that, prior to any such disclosure, the assignee or participant or proposed assignee or participant shall agree to comply with Section 8.14.

(h) Notwithstanding any other provision set forth in this Agreement, any Bank may at any time create a security interest in all or any portion of its rights under this Agreement (including, without limitation, the Revolving Credit Advances owing to it and the Note or Notes held by it) in favor of any Federal Reserve Bank in accordance with Regulation A of the Federal Reserve Board.

Section 8.09 No Liability of Issuing Banks. The Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. Neither any Issuing Bank nor any of its officers or directors shall be liable or responsible for: (a) the use that may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith; (b) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; (c) payment by such Issuing Bank against presentation of documents that do not comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to the Letter of Credit; or (d) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit, except that the Borrower shall have a claim against such Issuing Bank, and such Issuing Bank shall be liable to the Borrower, to the extent of any direct, but not consequential, damages suffered by the Borrower that the Borrower proves were caused by (i) such Issuing Bank’s willful misconduct or gross negligence as determined in a final, non-appealable judgment by a court of competent jurisdiction in determining whether documents presented under any Letter of Credit comply with the terms of the Letter of Credit or (ii) such Issuing Bank’s willful failure to make lawful payment under a Letter of Credit after the presentation to it of a draft and certificates strictly complying with the terms and conditions of the Letter of Credit. In furtherance and not in limitation of the foregoing, such Issuing Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

Section 8.10 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by facsimile shall be as effective as delivery of a manually executed counterpart of this Agreement.

Section 8.11 Judgment (a) If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder in Dollars into another currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Agent could purchase Dollars with such other currency at Citibank’s principal office in London at 11:00 A.M. (London time) on the Business Day preceding that on which final judgment is given.

(b) If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder in a Foreign Currency into Dollars, the parties agree to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Agent could purchase such Foreign Currency with Dollars at Citibank’s principal office in London at 11:00 A.M. (London time) on the Business Day preceding that on which final judgment is given.

(c) The obligation of the Borrower in respect of any sum due from it in any currency (the “Primary Currency”) to any Bank or the Agent hereunder shall, notwithstanding any judgment in any other currency, be discharged only to the extent that on the Business Day following receipt by such Bank or the Agent (as the case may be), of any sum adjudged to be so due in such other currency, such Bank or the Agent (as the case may be) may in accordance with normal banking procedures purchase the applicable Primary Currency with such other currency; if the amount of the applicable Primary Currency so purchased is less than such sum due to such Bank or the Agent (as the case may be) in the applicable Primary Currency, the Borrower agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Bank or the Agent (as the case may be) against such loss, and if the amount of the applicable Primary Currency so purchased exceeds such sum due to any Bank or the Agent (as the case may be) in the applicable Primary Currency, such Bank or the Agent (as the case may be) agrees to remit to the Borrower such excess.

Nothing herein shall affect the rights of any Bank or the Agent to serve legal process in any other manner permitted by law or affect the right that any party hereto may otherwise have to bring any action or proceeding relating to this Agreement, any of the Notes or any other instrument or document furnished pursuant hereto or in connection herewith in the courts of any other jurisdiction. Each of the Borrower, the Agent and the Banks hereby irrevocably and unconditionally waives, to the fullest extent it may effectively do so under applicable law, any right it may have to claim or recover in any action or proceeding referred to in this Section 8.13 any exemplary or punitive damages. The Borrower hereby further irrevocably waives, to the fullest extent it may effectively do so under applicable law, any right it may have to claim or recover in any action or proceeding referred to in this Section 8.13 any special or consequential damages.

Section 8.14 Confidentiality. Each Bank agrees that it will use reasonable efforts, to the extent not inconsistent with practical business requirements, not to disclose without the prior consent of the Borrower (other than to employees, auditors, accountants, counsel or other professional advisors of the Agent or any Bank) any information with respect to the Borrower, each Guarantor or their respective Subsidiaries which is furnished pursuant to this Agreement, provided that any Bank may disclose any such information (a) as has become generally available to the public, (b) as may be required or appropriate in any report, statement or testimony submitted to or required by any municipal, state or Federal regulatory body having or claiming to have jurisdiction over any Bank or its Affiliates or submitted to or required by the Federal Reserve Board or the Federal Deposit Insurance Corporation or similar organizations (whether in the United States or elsewhere) or their successors, and including any self-regulatory body having or claiming authority to regulate or oversee any aspect of any Bank’s or its Affiliates’ businesses, (c) as may be required or appropriate in response to any summons or subpoena in connection with any litigation, (d) in order to comply with any law, order, regulation or ruling applicable to any Bank, (e) to any assignee, participant, prospective assignee, or prospective participant that has agreed to comply with this Section 8.14, (f) in connection with the exercise of any remedy by any Bank pertaining to this Agreement, any of the Notes or any other document or instrument delivered in connection herewith, (g) in connection with any litigation involving any Bank pertaining to any Loan Document or any other document or instrument delivered in connection herewith, (h) to any Bank or the Agent, or (i) to any Affiliate of any Bank.
