(a) Each Borrowing shall be made on notice, given not later than noon (New York City time) (x) in the case of a proposed Borrowing comprised of LIBOR Advances, at least three Business Days prior to the date of the proposed Borrowing (or, as to any proposed Borrowing comprised of LIBOR Advances, at such other time as the applicable Borrower and the Banks may agree to for such proposed Borrowing) and (y) in the case of a proposed Borrowing comprised of Base Rate Advances, on the day of the proposed Borrowing, by the applicable Borrower to the Administrative Agent, which shall give to each Bank prompt notice thereof by telex or telecopy or in accordance with Section 8.17.

During such periods as such Advance is a LIBOR Advance, a rate per annum equal at all times during each Interest Period for such Advance to the sum of the LIBO Rate for such Interest Period for such Advance plus the Applicable Margin for such Interest Period, payable on the last day of such Interest Period, on each other date provided herein and, if such Interest Period has a duration of more than three months, on the day which occurs during such Interest Period three months from the first day of such Interest Period; provided that any amount of principal of any LIBOR Advance which is not paid when due

-21-

(whether at stated maturity, by acceleration or otherwise) shall bear interest, from the date on which such amount is due until such amount is paid in full, payable on demand, at a rate per annum equal at all times to the greater of (x) the sum of 2% per annum plus the Base Rate in effect from time to time, and (y) the sum of 2% per annum plus the rate per annum required to be paid on such Advance immediately prior to the date on which such amount became due.

SECTION 2.06. Additional Interest on LIBOR Advances. If any Bank is required under regulations of the Federal Reserve Board to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, and if as a result thereof there is an increase in the cost to such Bank of agreeing to make or making, funding or maintaining LIBOR Advances, then the applicable Borrower or Borrowers shall from time to time, upon demand by such Bank (with a copy of such demand to the Administrative Agent), unless such Bank withdraws its demand for such additional amounts pursuant to Section 2.16(b) or the applicable Borrower or Borrowers are not obligated to pay such amounts pursuant to Section 2.16(a), pay to the Administrative Agent for the account of such Bank additional amounts, as additional interest hereunder, sufficient to compensate such Bank for such increased cost. Such Bank shall provide to the applicable Borrower or Borrowers a reasonable explanation of such amounts to be paid.

SECTION 2.07. Interest Rate Determination and Protection. (a) The Administrative Agent shall give prompt notice to the Parent and the Banks of the applicable interest rate determined by the Administrative Agent for purposes of Section 2.05(b).

(b) If the Administrative Agent is unable to obtain timely information for determining the LIBO Rate for any LIBOR Advance,

(i) the Administrative Agent shall forthwith notify the Parent and the Banks that the interest rate cannot be determined for such LIBOR Advances,

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

(iii) the obligation of the Banks to make, or to Convert Advances or Borrowings into, or make divisions or combinations of Borrowings resulting in, LIBOR Advances or LIBOR Borrowings shall be suspended until the Administrative Agent shall notify the Parent and the Banks that the circumstances causing such suspension no longer exist.

(c) If the Majority Banks notify the Administrative Agent that either (A) the applicable interest rate for any Interest Period for any LIBOR Advance will not adequately reflect the cost to such Majority Banks of making, funding or maintaining their respective LIBOR Advances for such Interest Period, or (B) Dollar deposits in the amounts of their respective Advances for such Interest Period are not available to them in the London interbank market, the Administrative Agent shall forthwith so notify the Parent and the Banks, whereupon

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

-22-

(ii) the obligation of the Banks to make, or to Convert Advances or Borrowings into, or to make divisions or combinations of Borrowings resulting in, LIBOR Advances or LIBOR Borrowings shall be suspended until the Administrative Agent shall notify the Parent and the Banks that the circumstances causing such suspension no longer exist.

(d) If a Borrower shall fail to select the duration of any Interest Period for any LIBOR Advances in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01, the Administrative Agent will forthwith so notify such Borrower and the Banks and such Advances will automatically, on the last day of the then existing Interest Period therefor, Convert into LIBOR Advances with an Interest Period of one month.

(e) At the end of the relevant Interest Period following the date on which the aggregate unpaid principal amount of Advances comprising any LIBOR Borrowing shall be reduced, by payment or prepayment or otherwise, to less than $1,000,000, such Advances shall automatically Convert into Base Rate Advances, and on and after such date the right of the applicable Borrower to Convert such Advances into LIBOR Advances shall terminate; provided that if and so long as each such Advance shall be of the same Type and have an Interest Period ending on the same date as Advances comprising another Borrowing or other Borrowings, and the aggregate unpaid principal amount of all such Advances of all such Borrowings shall equal or exceed $1,000,000, the applicable Borrower shall have the right to continue all such Advances as, or to Convert all such Advances into, Advances of such Type having an Interest Period ending on such date.

(f) Upon the occurrence and during the continuance of an Event of Default, each LIBOR Advance shall automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance.

SECTION 2.08. Voluntary Conversion of Borrowings; Continuation of LIBOR Borrowings. (a) The applicable Borrower may on any Business Day, upon notice given to the Administrative Agent not later than noon (x) in the case of a proposed Conversion into a LIBOR Borrowing, on the third Business Day prior to the date of the proposed Conversion and (y) in the case of a proposed Conversion into a Base Rate Borrowing, on the date of the proposed Conversion and subject to the limitations in Section 2.02(a) as to the number of permitted Interest Periods and subject to the provisions of Sections 2.07, 2.08(c) and 2.11, Convert all or any portion of a Borrowing of one Type into a Borrowing of another Type; provided that any Conversion of any LIBOR Borrowing shall be made on, and only on, the last day of an Interest Period for such LIBOR Borrowing. Each such notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the Borrowing (or identified portion thereof) to be Converted and the Type into which it is to be Converted, and (iii) if such Conversion is into a LIBOR Borrowing, the duration of the Interest Period for each LIBOR Advance comprising such LIBOR Borrowing.

(b) The applicable Borrower may continue all or any portion of any LIBOR Borrowing as a LIBOR Borrowing for an additional Interest Period that complies with the requirements set forth in the definition herein of “Interest Period,” by giving notice of such Interest Period as set forth in such definition, subject to the limitations in Section 2.02(a) as to the number of permitted Interest Periods and subject to the provisions of Sections 2.07, 2.08(c) and 2.11.

-23-

(c) All Borrowings, divisions and combinations of Borrowings, Conversions and continuations under this Agreement shall be effected in a manner that (i) treats all Banks ratably (including, for example, effecting Conversions of any portion of a Borrowing in a manner that results in each Bank retaining its same ratable percentage of both the Converted portion and the remaining portion not Converted), and (ii) in the case of LIBOR Borrowings, results in each LIBOR Borrowing (including, in the case of any Conversion of a portion of a LIBOR Borrowing, both the Converted portion and the remaining portion not Converted) being in an amount not less than $1,000,000; provided that clause (ii) immediately above shall not limit the Borrowers’ rights under the proviso of Section 2.07(e). Upon Conversion of any Borrowing, or portion thereof, into a particular Type, all Advances comprising such Borrowing or portion thereof, as the case may be, will be deemed Converted into Advances of such Type. Notwithstanding any other provision hereof, during the continuance of any Event of Default no Borrower may divide or combine Borrowings, continue all or any portion of any LIBOR Borrowing for an additional Interest Period or Convert all or any portion of a Borrowing into a LIBOR Borrowing.

SECTION 2.09. Optional Prepayments. Each Borrower may (i) in respect of LIBOR Advances, upon at least two Business Days’ notice, and (ii) in respect of Base Rate Advances, upon notice by noon on the day of the proposed prepayment, to the Administrative Agent stating the proposed date and aggregate principal amount of the prepayment and the Types of Advances to be prepaid, and the specific Borrowing or Borrowings to be prepaid in whole or in part, and if such notice is given the applicable Borrower shall, 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 without premium or penalty; provided that each partial prepayment shall be in an aggregate principal amount not less than $10,000,000 (and in increments of $1,000,000 in excess thereof), and provided further that if such Borrower prepays any LIBOR Advance on any day other than the last day of an Interest Period therefor, such Borrower shall compensate the Banks pursuant to Section 8.04(b).

SECTION 2.10. Increased Costs; Capital Adequacy, Etc. (a) If, due to either (i) the introduction of or any change in or in the interpretation of any law or regulation by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof or (ii) the compliance with any guideline or request from any governmental authority, central bank or comparable agency (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 LIBOR Advances (other than increased costs described in Section 2.06 or in Section 2.10(c) below), then the applicable Borrower or Borrowers shall from time to time, upon demand by such Bank (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Bank additional amounts sufficient to compensate such Bank for such increased cost unless such Bank shall have withdrawn its demand for additional compensation for such increased cost pursuant to Section 2.16(b) or such Borrower is not obligated to pay such amounts pursuant to Section 2.16(a). Such Bank shall provide to such Borrower a reasonable explanation of such amounts to be paid by such Borrower.

-24-

(b) If the applicable Borrower so notifies the Administrative Agent within five Business Days after any Bank notifies such Borrower of any increased cost pursuant to the provisions of Section 2.10(a), such Borrower shall Convert all Advances of the Type affected by such increased cost of all Banks then outstanding into Advances of another Type in accordance with Section 2.08 and, additionally, reimburse such Bank for such increased cost in accordance with Section 2.10(a).

(c) If any Bank shall have determined that, after the date hereof, the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its lending office) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency (except to the extent such request or directive arises as a result of the individual creditworthiness of such Bank), has the effect of increasing the amount of capital required or expected to be maintained as a result of its Commitment hereunder or the existence of any Letter of Credit, such Bank shall have the right to give prompt written notice and demand for payment thereof to the applicable Borrower with a copy to the Administrative Agent (which notice and demand shall show in reasonable detail the calculation of such additional amounts as shall be required to compensate such Bank for the increased cost to such Bank as a result of such increase in capital and shall certify that such costs are generally being charged by such Bank to other similarly situated borrowers under similar credit facilities), although the failure to give any such notice shall not, unless such notice fails to set forth the information required above, release or diminish any of the Borrowers’ obligations to pay additional amounts pursuant to this Section 2.10(c), and subject to Section 2.16, such Borrower shall pay such additional amounts.

(d) Each Bank shall use its best 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 2.10 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.

(e) No Bank shall be entitled to recover increased costs pursuant to this Section 2.10, (a) incurred or accruing more than 90 days prior to the date on which such Bank sent to the applicable Borrower a written notice and demand for payment as specified in this Section 2.10, or (b) to the extent that such increased costs have resulted from the failure of such Bank to have complied with Section 2.10(d).

SECTION 2.11. Illegality. Notwithstanding any other provision of this Agreement, if the introduction of or any change in or in the interpretation of any law or regulation shall make it unlawful, or any governmental authority, central bank or comparable agency shall assert that it is unlawful (such unlawfulness or such assertion of unlawfulness being an “Illegality Event”), for any Bank or its Eurodollar Lending Office (such a Bank being an “Affected Bank”) to perform its obligations hereunder to make LIBOR Advances or to continue to fund or maintain LIBOR Advances hereunder, then, on notice thereof and demand therefor by such Bank to the applicable

-25-

Borrower through the Administrative Agent, (a) the obligation of the Banks to make, or to Convert Advances or Borrowings into, or to make divisions or combinations of Borrowings resulting in, LIBOR Advances or LIBOR Borrowings shall be suspended until the time set forth in the next succeeding sentence, and (b) the applicable Borrower shall forthwith Convert all LIBOR Advances of all Banks then outstanding into Advances of another Type in accordance with Section 2.08. The suspension of the obligation of the Banks to make LIBOR Advances or to continue to fund or maintain LIBOR Advances, as set forth in the preceding sentence, shall terminate upon the earliest to occur of the following: (i) the withdrawal by each Affected Bank of its notice and demand with respect to the Illegality Event referenced in this Section 2.11, (ii) the replacement by the Parent of each Affected Bank pursuant to Section 2.16(a) hereof with an Eligible Assignee that is not an Affected Bank, and (iii) the termination by the Parent of each Affected Bank pursuant to Section 2.16(b) hereof. If an Illegality Event has ceased to exist with respect to a Bank that has given notice and demand with respect to such Illegality Event pursuant to this Section 2.11, such Bank shall promptly withdraw such notice and demand by giving written notice of withdrawal to the Administrative Agent and the Parent. Upon termination of such suspension pursuant to clause (i), (ii) or (iii) above, as applicable, the Administrative Agent shall notify each Bank of such termination, and the Banks shall thereupon again be obligated to make LIBOR Advances and LIBOR Borrowings and to continue to fund, maintain, and Convert LIBOR Advances and LIBOR Borrowings in each case in accordance with and to the extent provided in this Agreement.

SECTION 2.12. Payments and Computations. (a) Each Borrower shall make each payment under any Loan Document not later than noon on the day when due in Dollars to the Administrative Agent at its Payment Office (or to the Issuing Bank, in the case of payments to the Issuing Bank under Section 2.18) in same day funds. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal, interest, fees or commissions on Letters of Credit as contemplated by Section 2.18(b) ratably (other than amounts payable pursuant to Section 2.06, 2.10, 2.13, 2.16 or 8.04) to the Banks (decreased, as to any Bank, for any taxes withheld in respect of such Bank as contemplated by Section 2.13(b)) 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 8.06(c), from and after the effective date specified in such Assignment and Acceptance, the Administrative Agent shall make all payments hereunder and under the Notes (if any) 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 Administrative Agent, the applicable Borrower shall notify the Administrative Agent of the Borrowing to which such payment shall apply. In the absence of such notice, the Administrative 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) shall be made by the Administrative 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 LIBO Rate, the Federal Funds Rate, of any fee payable

-26-

under Section 2.03, Section 2.18(b), 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 Administrative Agent, and all computations of interest pursuant to Section 2.06 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 Administrative Agent (or, in the case of Section 2.06, 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 (if any) 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 or fees, as the case may be; provided that if such extension would cause payment of interest on or principal of LIBOR Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(d) Unless the Administrative Agent shall have received notice from a Borrower prior to the date on which any payment is due to the Banks hereunder that such Borrower will not make such payment in full, the Administrative Agent may assume that such Borrower has made such payment in full to the Administrative Agent on such date and the Administrative 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 such Borrower shall not have so made such payment in full to the Administrative Agent, each Bank shall repay to the Administrative 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 Administrative Agent, at the Federal Funds Rate.

SECTION 2.13. Taxes. (a) Any and all payments by the Borrowers hereunder or under the Notes (if any) shall be made, in accordance with Section 2.12, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges, fees, duties or withholdings, and all liabilities with respect thereto, excluding, in the case of each Bank and the Administrative Agent, (1) taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction under the laws of which (or by a jurisdiction under the laws of a political subdivision of which) such Bank or Administrative Agent (as the case may be) is organized or any political subdivision thereof and, in the case of each Bank, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction of such Bank’s Applicable Lending Office or any political subdivision thereof and (2) any taxes imposed by the United States of America by means of withholding at the source if and to the extent that such taxes shall be in effect and shall be applicable, on the date hereof (or, with respect to any entity that becomes a Bank after the date hereof, on the date such entity becomes a Bank), to payments to be made to such Bank or the Administrative Agent (all such non-excluded taxes, levies, imposts, deductions, charges, fees, duties, withholdings and liabilities being hereinafter referred to as “Taxes”). If a Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Note (if any) to any Bank or the Administrative Agent, (i) the sum payable shall be increased 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 Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions

-27-

been made, (ii) such Borrower shall make such deductions, and (iii) such Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) Notwithstanding anything to the contrary contained in this Agreement, each of the Borrowers and the Administrative Agent shall be entitled, to the extent they are required to do so by law, to deduct or withhold income or other similar taxes imposed by the United States of America from interest, fees or other amounts payable hereunder for the account of any Bank (without the payment by a Borrower of increased amounts to such Bank pursuant to clause (a) above) other than a Bank (i) which is a domestic corporation (as such term is defined in Section 7701 of the Code) for federal income tax purposes or (ii) which has the duly executed Prescribed Forms on file with the Parent and the Administrative Agent for the applicable year to the extent deduction or withholding of such taxes is not required as a result of the filing of such duly executed Prescribed Forms, provided that if a Borrower shall so deduct or withhold any such taxes, it shall provide a statement to the Administrative Agent and such Bank, setting forth the amount of such taxes so deducted or withheld, the applicable rate and any other information or documentation which such Bank or the Administrative Agent may reasonably request for assisting such Bank or the Administrative Agent to obtain any allowable credits or deductions for the taxes so deducted or withheld in the jurisdiction or jurisdictions in which such Bank is subject to tax.

(c) In addition, each 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 (if any) or from the execution, delivery or registration of, or otherwise with respect to, this Agreement or the Notes (hereinafter referred to as “Other Taxes”).

(d) Each Borrower, to the fullest extent permitted by law, will indemnify each Bank and the Administrative Agent for the full amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.13) paid by such Bank or the Administrative Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted, except (i) if such Taxes, Other Taxes, or other liability arise as a result of the gross negligence or willful misconduct of such Bank or Administrative Agent or (ii) if such Taxes, Other Taxes, or other liability arise as a result of such Bank’s failure to file any Prescribed Forms which are available to it and for which it qualifies. This indemnification shall be made within 30 days from the date such Bank or the Administrative Agent (as the case may be) makes written demand therefor. No Bank nor the Administrative Agent shall be indemnified for Taxes incurred or accrued more than 90 days prior to the date that such Bank or the Administrative Agent notifies the applicable Borrower thereof.

(e) Within 30 days after the date of any payment of Taxes by or at the direction of a Borrower, such Borrower will furnish to the Administrative Agent, at its address referred to in Section 8.02, (i) the original or a certified copy of a receipt evidencing payment thereof, if the relevant taxing authority provides a receipt, or (ii) if the relevant taxing authority does not provide a receipt, other reasonable evidence of the payment thereof. Should any Bank or the Administrative Agent ever receive any refund, credit or deduction from any taxing authority to

-28-

which such Bank or the Administrative Agent would not be entitled but for the payment by a Borrower of Taxes as required by this Section 2.13 (it being understood that the decision as to whether or not to claim, and if claimed, as to the amount of any such refund, credit or deduction shall be made by such Bank or the Administrative Agent in its sole discretion), such Bank or the Administrative Agent, as the case may be, thereupon shall repay to such Borrower an amount with respect to such refund, credit or deduction equal to any net reduction in taxes actually obtained by such Bank or the Administrative Agent, as the case may be, and determined by such Bank or the Administrative Agent, as the case may be, to be attributable to such refund, credit or deduction.

(f) Each Bank shall use its best 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 Taxes or Other Taxes or to eliminate the amount of any such additional amounts 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.

(g) Without prejudice to the survival of any other agreement of the Borrowers hereunder, the agreements and obligations of the Borrowers contained in this Section 2.13 shall survive the payment in full of principal and interest hereunder and under the Notes.

SECTION 2.14. Sharing of Payments, Etc. (a) 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 Advances made by it (other than pursuant to Section 2.06, 2.10, 2.13, 2.16 or 8.04) in excess of its ratable share of payments on account of the Advances obtained by all the Banks, such Bank shall forthwith purchase from the other Banks such participations in the Advances made by them as shall be necessary to cause such purchasing Bank to share the excess payment ratably with each of them, provided 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 its 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.

(b) Each 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 such Borrower in the amount of such participation.

SECTION 2.15. Ratable Reduction or Termination of the Commitments; Effect of Termination. (a) The Parent shall have the right, upon at least three Business Days’ notice to the Administrative Agent, to terminate in whole or reduce ratably in part the unused portions of the respective Commitments of the Banks, provided that each partial reduction shall be in the aggregate amount of at least $10,000,000 or any whole multiple of $1,000,000 in excess thereof. Commitments terminated or reduced pursuant to the preceding sentence may not be reinstated.

-29-

(b) Upon and at all times after any Commitment of any Bank is terminated in whole pursuant to any provision of this Agreement, such Commitment shall be zero and such Bank shall have no further obligation to make any Advances.

SECTION 2.16. Replacement of Bank; Additional Right to Terminate Commitments. In the event that any Bank demands payment pursuant to Section 2.06, 2.10 or 2.13, or any Bank becomes an Affected Bank as set forth in Section 2.11, the Parent shall have the right, within 45 days after the date of the giving by such Bank of any notice or demand required or otherwise permitted to be given pursuant to Section 2.06, 2.10, 2.11 or 2.13 and if no Event of Default or Default then exists, to either replace such Bank in accordance with the procedure set forth in Section 2.16(a) or terminate all of such Bank’s Commitments in accordance with the procedure set forth in Section 2.16(b); provided that no such replacement or termination shall be effected without (i) the prior written consent of the Issuing Bank (such consent not to be unreasonably withheld, but any withholding of consent by the Issuing Bank based on any good faith concern of the Issuing Bank regarding the creditworthiness of the replacement Bank shall be deemed a reasonable withholding of consent), (ii) in the case of a termination pursuant to Section 2.16(b), a simultaneous reduction of the Letters of Credit in amounts such that there is no increase in the potential exposure of the Issuing Bank that is not participated to other Banks hereunder, and (iii) in the case of the replacement or termination of the Bank that is the Issuing Bank, termination of all Letters of Credit issued by such Issuing Bank.

(a) If the Parent determines to replace a Bank pursuant to this Section 2.16, then the Parent will have the right to replace such Bank with an Eligible Assignee in accordance with Section 8.06(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 Administrative Agent) to purchase all of such Bank’s rights hereunder and interest in the Advances owing to such Bank and the Note (if any) held by such Bank without recourse at the principal amount of such Note plus interest and accrued fees to the date of such purchase on a date therein specified, and (ii) shall execute and deliver to the Administrative 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, respectively, prior to such replacement); provided, further, that no Bank or other Person shall have any obligation to increase any of its Commitments or otherwise to replace, in whole or in part, any Bank. Upon satisfaction of the requirements set forth in the first sentence of this Section 2.16(a), acceptance of such offer to purchase by the Bank to be replaced, payment to such Bank of the purchase price in immediately available funds, and the payment by the Borrowers of all requested costs accruing to the date of purchase which the Borrowers are obligated to pay under Section 8.04 and all other amounts owed by the Borrowers to such Bank (other than the principal of and interest on the Advances of such Bank and accrued fees to the date of such purchase that are purchased by such Eligible Assignee), such Eligible Assignee shall constitute a “Bank” hereunder with Commitments as so specified and the Bank being so replaced shall no longer constitute a “Bank” hereunder and all of its Commitments shall be deemed terminated, except that the rights under Sections 2.06, 2.10, 2.13 and 8.04 of the Bank being so replaced shall

-30-

continue with respect to events and occurrences occurring 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, the Borrowers shall continue to be obligated to pay the increased costs and additional amounts due to such Bank pursuant to Sections 2.06, 2.10 and 2.13 (if a demand or notice for payment of increased costs or additional amounts pursuant to any of such Sections is the basis of the proposed replacement), or (y) the Bank proposed to be replaced fails to accept such purchase offer, the Borrowers (if a demand or notice for payment of increased costs or additional amounts pursuant to any of such Sections is the basis of the proposed replacement) 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, and neither the failure to purchase as set forth in clause (x) of this sentence nor the failure to accept a purchase offer as set forth in clause (y) of this sentence, shall affect any rights the Borrowers may have to terminate such Bank’s Commitments in accordance with Section 2.16(b).

(b) In the event that the Parent determines to terminate a Bank’s Commitments pursuant to this Section 2.16, the Parent shall have the right to terminate such Bank’s Commitments and shall give notice to such Bank of the Parent’s election to terminate (a copy of such notice to be sent to the Administrative Agent), and such termination shall become effective on the date specified in such notice (which shall be 15 days after the date of such notice, provided that if the 15th day after the date of such notice is not a Business Day, the date specified in such notice shall be the first Business Day next succeeding such 15th day) unless such Bank withdraws its demand or notice for increased costs or additional amounts (if such a demand or notice is the basis for the proposed termination). On the date of the termination of the Commitments of any Bank pursuant to this Section 2.16(b), the Borrowers shall pay all amounts owed by the Borrowers to such Bank under this Agreement and under the Note payable to such Bank (including principal of and interest on the Advances owed to such Bank, accrued fees and amounts specified in such Bank’s notice and demand (if any) delivered pursuant to Sections 2.06, 2.10 or 2.13, as the case may be, with respect to the period prior to such termination) and such Bank shall thereupon cease to be a “Bank” hereunder for all purposes and its Commitments shall be deemed terminated, except that such Bank’s rights under Sections 2.06, 2.10, 2.13 and 8.04 shall continue with respect to events and occurrences occurring before or concurrently with its ceasing to be a “Bank” hereunder.

SECTION 2.17. Certificates of Banks. Without limitation to the requirements of Section 2.10(c), any Bank demanding or giving notice of amounts due to such Bank under this Article II shall, as part of each demand or notice for payment required under this Article II, deliver to the applicable Borrower (with a copy to the Administrative Agent) a certificate setting forth in reasonable detail the amount and basis of the increased costs or additional amounts payable to such Bank hereunder and such certificate shall be conclusive and binding on such Borrower in the absence of manifest error.

SECTION 2.18. Letters of Credit. (a) The Issuing Bank agrees, on the terms and conditions herein set forth, to issue Letters of Credit for the account of each Borrower from time to time on any Business Day during the period from the date hereof until one calendar week before the Termination Date; provided that (i) at no time shall the Letter of Credit Liabilities exceed $100,000,000, (ii) at no time shall the EOIC Letter of Credit Liabilities exceed the EOIC

-31-

Sublimit minus the aggregate outstanding principal amount of Advances to EOIC, (iii) no Letter of Credit shall have a Stated Expiry Date later than the earlier of (A) one year from the date of its issuance unless otherwise extended by the Issuing Bank or, subject to the consent of the Issuing Bank, such Letters of Credit contain language providing for their automatic renewal or (B) the Termination Date, and (iv) at no time shall a Letter of Credit be issued if, after giving effect thereto, any Bank’s Ratable Portion of the Letter of Credit Liabilities plus the aggregate amount of Advances owed to such Bank exceed such Bank’s Commitment. In the case of a Letter of Credit containing language providing for its automatic renewal, each Borrower acknowledges and agrees that, if any such automatic renewal would cause the Stated Expiry Date of such Letter of Credit to be later than the Termination Date, the Issuing Bank may give notice to the beneficiary of such Letter of Credit that such automatic renewal shall not take place. Each Letter of Credit shall be issued on notice given by a Borrower to the Issuing Bank and the Administrative Agent (which shall give to each Bank prompt notice thereof) not later than noon on the third Business Day prior to the date of the issuance of the proposed Letter of Credit. Each such notice of a Letter of Credit (a “Notice of Letter of Credit”) shall be given in accordance with Section 8.02, in substantially the form of Exhibit D, specifying therein the requested (A) date of issuance of such Letter of Credit (which shall be a Business Day), (B) the Borrower for whose account such Letter of Credit is to be issued, (C) the amount of such Letter of Credit (which must be in Dollars), (D) expiration date of such Letter of Credit, and (E) purpose and terms of such Letter of Credit (which shall not be to secure Debt). Additionally, if requested by the Issuing Bank, the applicable Borrower shall execute and deliver to the Issuing Bank, an application for letter of credit on the Issuing Bank’s standard form or on another form agreed upon by such Borrower and the Issuing Bank.

(b) With respect to each Letter of Credit, the Borrowers agree to pay (i) to the Issuing Bank an issuance fee of 1/8^th of 1% per annum and (ii) to the Administrative Agent a commission (which commission shall be shared ratably by all Banks (including the Issuing Bank) based on their respective Ratable Portions) of the per annum rate equal to the Applicable Letter of Credit Margin in effect from time to time, in each case computed on the basis of a year of 360 days for the actual number of days elapsed, on the maximum face amount of such Letter of Credit, from the date of issuance of such Letter of Credit until the Expiration Date for such Letter of Credit, payable monthly in arrears on the last Business Day of each month and on such Expiration Date. Additionally, the Borrowers agree to pay all standard costs, fees, expenses, administrative, issuance, amendment, payment and negotiation charges of the Issuing Bank in connection with each Letter of Credit (including mailing charges and out-of-pocket expenditures).

(c) The Borrowers will immediately and unconditionally pay to the Issuing Bank upon demand the amount of each payment made under any Letter of Credit. If the Borrowers shall fail to pay to the Issuing Bank the amount of any such payment immediately upon demand in accordance with the terms of this Agreement, such payment shall immediately constitute, without necessity of further act or evidence, a loan (a “Demand Loan”) made by the Issuing Bank to the applicable Borrower on the date of such payment in a principal amount equal to such payment and repayable upon demand, together with interest on the principal amount of such Demand Loan remaining unpaid from time to time, payable on demand and computed from the date such Demand Loan is made as specified above to the date of repayment in full thereof, at a rate per annum equal to the sum of the Base Rate in effect from time to time plus 2% per annum.

-32-

(d) The obligations of the Borrowers under this Agreement and any other agreement or instrument relating to any Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement and such other agreement or instrument under all circumstances, including the following circumstances:

(i) any lack of validity or enforceability of this Agreement, any Letter of Credit or any other agreement or instrument relating thereto (collectively, the “L/C Related Documents”);

(ii) any change in the time, manner or place of payment of, or in any other term of, all or any of the obligations of either Borrower in respect of any Letter of Credit or any other amendment or waiver of or any consent to departure from all or any of the L/C Related Documents;

(iii) the existence of any claim, set-off, defense or other right that either Borrower may have at any time against any beneficiary or transferee of any Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), the Issuing Bank or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or by the L/C Related Documents or any other transaction;

(iv) any statement or any other document presented under any Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

(v) payment by the Issuing Bank under any Letter of Credit against presentation of a draft or document that does not comply with the terms of such Letter of Credit; or

(vi) any exchange, release or non-perfection of any collateral for, or any release or amendment or waiver of or consent to departure from any guarantee of, all or any of the obligations of the Borrower in respect of any Letter of Credit;

however, this Section 2.18(d) shall not limit any right of a Borrower to make a claim against the Issuing Bank to the extent provided in Section 2.18(e).

(e) Each Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to the use of such Letter of Credit. Neither the Issuing Bank nor any branch, affiliate or correspondent bank of the Issuing Bank nor any of their respective employees, agents, officers or directors shall be liable or responsible for: (i) the use that may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee of any Letter of Credit in connection therewith; (ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be invalid, insufficient, fraudulent or forged; (iii) payment by the Issuing Bank against presentation of documents that do not strictly comply with the terms of the relevant Letter of Credit, including failure of any documents to bear any reference or adequate reference to the relevant Letter of Credit; or (iv) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit; provided that, notwithstanding clauses (i) through (iv) of this sentence, the applicable Borrower shall have a claim against the Issuing Bank, and the

-33-

Issuing Bank shall be liable to such Borrower, to the extent of any direct, but not consequential or other, damages suffered by such Borrower that such Borrower proves were caused by (A) the Issuing Bank’s willful misconduct or gross negligence in determining whether documents presented under a Letter of Credit comply with the terms of such Letter of Credit, (B) the Issuing Bank’s willful failure to make lawful payment under a Letter of Credit after the presentation to it of a draft and documents strictly complying with the terms and conditions of such Letter of Credit, or (C) the Issuing Bank’s failure to comply with the ICC Uniform Customs and Practice for Documentary Credits (UCP 500), International Chamber of Commerce Publication No. 500, 1993 Revision. In furtherance and not in limitation of the foregoing, the 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.

(f) Upon the date of the issuance of a Letter of Credit, the Issuing Bank shall be deemed to have sold to each other Bank and each other Bank shall have been deemed to have purchased from the Issuing Bank a ratable participation in the related Letter of Credit Liabilities and all related Demand Loans equal to such Bank’s Ratable Portion at such date and such sale and purchase shall otherwise be in accordance with the terms of this Agreement. The Issuing Bank shall promptly notify each such participant Bank by telex, telecopy, or email of each Letter of Credit issued or increased, the amount of such Bank’s participation in such Letter of Credit and each payment thereunder. Upon the making of any payment under any Letter of Credit, each Bank (other than the Issuing Bank) shall pay for the purchase of its participation therein by immediate payment to the Issuing Bank of same day funds in the amount of its participation in such payment.

SECTION 2.19. Increase in Commitments.

(a) Request for Increase. Provided there exists no Event of Default or Material Adverse Effect, upon notice to the Administrative Agent (which shall promptly, but in any event within 3 Business Days after receipt of such notice, notify the Banks), the Parent may request an increase in the aggregate Commitments by an amount not exceeding $150,000,000; provided that any such request for an increase shall be in a minimum amount of $50,000,000. At the time of sending such notice, the Parent (in consultation with the Administrative Agent) shall specify the time period within which each Bank is requested to respond (which shall in no event be less than ten Business Days from the date of delivery of such notice to the Banks).

(b) Bank Elections to Increase. Each Bank shall notify the Administrative Agent within such time period whether or not it agrees to increase its Commitment and, if so, whether by an amount equal to, greater than, or less than its Ratable Portion of such requested increase. Any Bank not responding within such time period shall be deemed to have declined to increase its Commitment.

(c) Notification by Administrative Agent; Additional Banks. The Administrative Agent shall notify the Parent and each Bank of the Banks’ responses to each request made hereunder. To achieve the full amount of a requested increase and subject to the approval of the Administrative Agent and the Issuing Bank (which approvals shall not be unreasonably withheld or delayed), the Parent may also invite additional Eligible Assignees to become Banks pursuant to a joinder agreement in form and substance satisfactory to the Administrative Agent and its counsel.

-34-

If the aggregate Commitments are increased in accordance with this Section, the Administrative Agent and the Parent shall determine the effective date (the “Increase Effective Date”) and the final allocation of such increase. The Administrative Agent shall promptly notify the Parent and the Banks of the final allocation of such increase and the Increase Effective Date.

(e) Conditions to Effectiveness of Increase. As a condition precedent to such increase, the Parent shall deliver to the Administrative Agent a certificate of each Borrower dated as of the Increase Effective Date (in sufficient copies for each Bank) signed by a Responsible Person of such Borrower (i) certifying and attaching the resolutions adopted by such Borrower approving or consenting to such increase, and (ii) certifying that, before and after giving effect to such increase, (A) the representations and warranties contained in Article IV and the other Loan Documents are true and correct on and as of the Increase Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they were true and correct as of such earlier date, and except that for purposes of this Section, the representations and warranties contained in clauses (i) and (ii) of Section 4.01(d) shall be deemed to refer to the most recent financial statements furnished pursuant to clauses (ii) and (i), respectively, of Section 5.01(a), and (B) no Event of Default or Material Adverse Effect exists or would be caused by such increase. The Borrowers shall prepay any Advances outstanding on the Increase Effective Date (and pay any additional amounts required pursuant to Section 8.04(b)) to the extent necessary to keep the outstanding Advances ratable with any revised Ratable Portions arising from any nonratable increase in the Commitments under this Section.

(f) Update of Representations and Warranties. Upon and after any increase of aggregate Commitments pursuant to this Section 2.19:

(i) the representation and warranties contained in Sections 4.01(d)(i) and (ii) shall be deemed to refer to the financial statements furnished most recently prior to the Increase Effective Date, pursuant to Section 5.01(a)(ii) and (i), respectively; and

(ii) the representation and warranty contained in Section 4.01(d)(iii) shall be deemed to refer to the time period from December 31, 2004 through the Increase Effective Date, rather than the time period from December 31, 2004 through the date of this Agreement.

-35-

Borrowers, or by any Borrower acting singly, shall be valid and effective if given only by the Parent, whether or not EOIC joins therein. Any notice, demand, consent, acknowledgement, direction, certification or other communication delivered to the Parent in accordance with the terms of this Agreement shall be deemed to have been delivered to each Borrower.

(a) The Parent is a corporation validly formed and validly existing under the laws of the State of Delaware. EOIC is an exempted company validly formed and validly existing under the laws of the Cayman Islands. Each Material Subsidiary is duly organized or validly formed, validly existing and (if applicable) in good standing in each case under the laws of its jurisdiction of incorporation or formation. Each Borrower has, and each Material Subsidiary has, all requisite powers and all material governmental licenses, authorizations, consents and approvals required in each case to carry on its business as now conducted.

(b) The execution, delivery and performance by each Borrower of this Agreement, the Notes and each other Loan Document to which it is or will be a party are within such Borrower’s powers, have been duly authorized by all necessary action of such Borrower, require, in respect of such Borrower, no action by or in respect of, or filing with, any governmental body, agency or official and do not contravene, or constitute a default under, (i) any provision of law or regulation (including Regulation X issued by the Federal Reserve Board) applicable to such Borrower, (ii) Regulation U issued by the Federal Reserve Board, (iii) its Bylaws, Articles of

-38-

Incorporation, or other organizational or governing documents, or (iv) any judgment, injunction, order, decree or agreement binding upon such Borrower, or result in the creation or imposition of any Lien (other than a Lien created in connection with this Agreement) on any asset of such Borrower or any of its Restricted Subsidiaries.

(c) This Agreement and each Note are, and each other Loan Document to which a Borrower is or will be a party, when executed and delivered in accordance with this Agreement will be, legal, valid and binding obligations of such Borrower enforceable against such Borrower in accordance with their respective terms, except as the enforceability thereof may be limited by the effect of any applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally and by general principles of equity.

(d) In each case, subject to Section 2.19(f):

(i) The balance sheet of the Parent as at December 31, 2004, duly certified by the chief executive officer or the chief financial officer of the Parent, copies of which have been furnished to each Bank, fairly presents in all material respects the financial condition of the Parent as at such date and such balance sheet was prepared in accordance with GAAP, except as specifically noted therein.

(f) No Termination Event has occurred or is reasonably expected to occur with respect to any Plan for which an Insufficiency exists that could reasonably be expected to cause a Material Adverse Effect. Neither any Borrower nor any ERISA Affiliate has received any notification (or has knowledge of any reason to expect) that any Multiemployer Plan is in reorganization or has been terminated, within the meaning of Title IV of ERISA, for which a Withdrawal Liability exists that could reasonably be expected to cause a Material Adverse Effect.

(g) The Parent and the Material Subsidiaries have filed or caused to be filed all United States federal income tax returns and all other material domestic tax returns which to the

-39-

knowledge of the Parent are required to be filed by them and have paid or provided for the payment, before the same become delinquent, of all taxes due pursuant to such returns or pursuant to any assessment received by a Borrower or any Material Subsidiary, other than those taxes contested in good faith by appropriate proceedings.

(k) Neither the Parent nor any of its Subsidiaries is in default under or with respect to, nor has any event or circumstance occurred which, but for the passage of time or the giving of notice or both, would constitute a default by the Parent or any of its Subsidiaries under or with respect to, any contract, agreement, lease or other instrument to which the Parent or such Subsidiary is a party and which could reasonably be expected to cause a Material Adverse Effect, and no Default or Event of Default exists.

(l) The Parent and each of the Material Subsidiaries have been and are in compliance in all respects with all applicable Environmental Laws, except to the extent that failure to comply with such Environmental Laws could not reasonably be expected to have a Material Adverse Effect.

There are no facts or conditions or circumstances known to the Parent that the Parent reasonably believes could form the basis for any action, lawsuit, claim or proceeding involving the Parent or any of its Subsidiaries or their respective past or present Properties, businesses or operations relating to the Environment or

-40-

Environmental matters, including any action, lawsuit, claim or proceeding arising from past or present practices or operations asserted under any Environmental Law, that in the aggregate could reasonably be expected to have a Material Adverse Effect.

(m) The Parent and its Material Subsidiaries (i) have good, valid and indefeasible title to their respective property and to all property reflected by the balance sheet referred to in Section 4.01(d)(i) as being owned by the Parent, in each case free and clear of all Liens except Permitted Liens and (ii) maintain insurance in compliance with Section 5.01(d).

(n) Neither the Parent nor any of its Subsidiaries is a party to any agreement or instrument or subject to any restriction or any court order, writ, injunction or decree which, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

(o) No statement, information, exhibit, representation, warranty or report contained in any Loan Document or furnished to any of the Administrative Agent, the Syndication Agent, the Issuing Bank or any Bank in connection with or pursuant to any Loan Document or the preparation or negotiation of any Loan Document contains any material misstatement of fact or omitted to state a material fact or any fact necessary to make the statements contained therein not materially misleading when taken as a whole in light of the time and the circumstances under which such statements were made.

(p) Neither of the Borrowers nor any Material Subsidiary (i) is in violation of any Governmental Requirement or (ii) has failed to obtain any license, permit, franchise or other governmental authorization necessary to the ownership of any of its respective properties or the conduct of its respective businesses, except such violations and failures which could not reasonably be expected to have in the aggregate (in the event that such violation or failure were asserted by any Person through appropriate action) a Material Adverse Effect.

(q) The Borrowers and each of the Material Subsidiaries are qualified to own and operate the Rigs under the laws of the United States, the Bahamas, Liberia, and Panama, as may be applicable.

(r) Each Rig is classified in the highest class available for rigs or vessels of its age and type with the American Bureau of Shipping, Inc. or another internationally recognized classification society reasonably acceptable to the Administrative Agent, free of any material outstanding requirements or recommendations.

THE ADMINISTRATIVE AGENT AND THE ISSUING BANK

Each Bank hereby appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under the Loan Documents as are delegated to the Administrative Agent, by the terms hereof and thereof, together with such powers and discretion as are reasonably incidental thereto. As to any matters not expressly provided for by the Loan Documents (including enforcement or collection of the Notes), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Majority Banks, and such instructions shall be binding upon all Banks and all holders of Notes; provided that the Administrative Agent shall not be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to any Loan Document or applicable law and shall not be required to initiate or conduct any litigation or other proceedings. The Administrative Agent agrees to give to each Bank prompt notice of each notice given to it by the Borrowers pursuant to the terms of this Agreement.

SECTION 7.02. Administrative Agent’s Reliance, Etc. Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with any Loan Document, except for its or their own gross negligence or willful misconduct. The duties of the Administrative Agent shall be mechanical and administrative in nature; the Administrative Agent shall not have, by reason of this Agreement or any other Loan Document a fiduciary relationship in respect of any Bank or the holder of any Note; and nothing in this Agreement or any other Loan Document, expressed or implied, is intended or shall be so construed as to impose upon the Administrative Agent any obligations in respect of this Agreement or any other Loan Document except as expressly set forth herein. Without limitation of the generality of the foregoing, the Administrative Agent: (i) may treat the payee of any Note as the holder thereof until the Administrative Agent receives and accepts an Assignment and Acceptance entered into by the Bank that is the payee of such Note, as assignor, and an Eligible Assignee, as assignee, as provided in 8.06; (ii) may consult with legal

counsel (including counsel for the Borrowers), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (iii) makes no warranty or representation to any Bank and shall not be responsible to any Bank for any statements, warranties or representations (whether written or oral) made in or in connection with any Loan Document or any other instrument or document furnished pursuant hereto or in connection herewith; (iv) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of any Loan Document or any other instrument or document furnished pursuant hereto or in connection herewith on the part of the Borrowers or any other Person or to inspect the property (including the books and records) of the Borrowers or any other Person; (v) shall not be responsible for the due 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; and (vi) shall incur no liability under or in respect of any Loan Document, except for its own gross negligence or willful misconduct, by acting upon any notice, consent, certificate or other instrument or writing (which may be by telecopier, cable or telex) believed by it to be genuine and signed, given or sent by the proper party or parties.

SECTION 7.03. Administrative Agent and Its Affiliates. With respect to its Commitment, the Advances made by it and the Notes issued to it, each Bank which is also the Administrative Agent shall have the same rights and powers under the Loan Documents as any other Bank and may exercise the same as though it were not the Administrative Agent; and the term “Bank” or “Banks” shall, unless otherwise expressly indicated, include any Bank serving as the Administrative Agent in its individual capacity. Any Bank serving as the Administrative Agent and its affiliates may accept deposits from, lend money to, act as trustee under indentures of, accept investment banking engagements from and generally engage in any kind of business with, the Parent, any of its Subsidiaries and any Person who may do business with or own securities of the Parent or any of its Subsidiaries, all as if such Bank were not the Administrative Agent and without any duty to account therefor to the Banks.

SECTION 7.04. Bank Credit Decision. Each Bank acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Bank and based on the financial statements referred to in Section 4.01(d) and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent 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 and the other Loan Documents.

SECTION 7.05. Certain Rights of the Administrative Agent. If the Administrative Agent shall request instructions from the Majority Banks with respect to any act or action (including failure to act) in connection with this Agreement or any other Loan Document, the Administrative Agent shall be entitled to refrain from such act or taking such action unless and until the Administrative Agent shall have received instructions from the Majority Banks; and it shall not

-51-

incur liability to any Person by reason of so refraining. Without limiting the foregoing, no Bank nor the holder of any Note shall have any right of action whatsoever against the Administrative Agent as a result of its acting or refraining from acting hereunder or under any other Loan Document in accordance with the instructions of the Majority Banks or all of the Banks, as the case may be. Furthermore, except for action expressly required of the Administrative Agent hereunder, the Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall be specifically indemnified to its satisfaction by the Banks against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action.

SECTION 7.06. Holders. Any request, authority or consent of any Person who, at the time of making such request or giving such authority or consent, is the holder of any Note shall be conclusive and binding on any subsequent holder, transferee, assignee or endorsee, as the case may be, of such Note or of any Note or Notes issued in exchange therefor.

SECTION 7.07. Indemnification. The Banks agree to indemnify the Administrative Agent (to the extent not reimbursed by the Borrowers), ratably according to the respective principal amounts of the Notes then held by each of them (or if no principal of the Notes is at the time outstanding or if any principal of the Notes is held by any Person which is not a Bank, ratably according to the respective amounts of their Commitments then existing, or, if no such principal amounts are then outstanding (or if any principal of the Notes is held by any Person which is not a Bank) and no Commitments are then existing, ratably according to the respective amounts of the Commitments existing immediately prior to the termination thereof), from and against any and all claims, damages, losses, liabilities and expenses (including reasonable fees and disbursements of counsel) of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of any of the Loan Documents or any action taken or omitted by the Administrative Agent under the Loan Documents (EXPRESSLY INCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY OR EXPENSE ATTRIBUTABLE TO THE ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE OF SUCH INDEMNIFIED PARTY, BUT EXCLUDING ANY SUCH CLAIM, DAMAGE, LOSS, LIABILITY OR EXPENSE ATTRIBUTABLE TO THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE ADMINISTRATIVE AGENT). IT IS THE INTENT OF THE PARTIES HERETO THAT THE ADMINISTRATIVE AGENT SHALL, TO THE EXTENT PROVIDED IN THIS SECTION 7.07, BE INDEMNIFIED FOR ITS OWN ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE. Without limitation of the foregoing, each Bank agrees to reimburse the Administrative Agent promptly upon demand for such Bank’s ratable share of any reasonable out-of-pocket expenses (including reasonable counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, the Loan Documents, or any of them, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrowers.

SECTION 7.08. Resignation by the Administrative Agent. (a) The Administrative Agent may resign from the performance of all its functions and duties hereunder and under the other Loan Documents at any time by giving 15 Business Days’ prior written notice to the Parent and the Banks. Such resignation shall take effect upon the appointment of a successor Administrative Agent pursuant to clauses (b) and (c) below or as otherwise provided below.

SECTION 7.11. Bank Credit Decision. Each Bank acknowledges that it has, independently and without reliance upon the Issuing Bank or any other Bank and based on the financial statements referred to in Section 4.01(d) and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank also acknowledges that it will, independently and without reliance upon the Issuing 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 and the other Loan Documents.

(a) The Issuing Bank may resign from the performance of all its functions and duties hereunder and under the other Loan Documents at any time by giving 15 Business Days’ prior written notice to the Administrative Agent, the Parent, and the Banks. Such resignation shall take effect upon the appointment of a successor Issuing Bank pursuant to clauses (b) and (c) below or as otherwise provided below.

(b) Upon any such notice of resignation, the Majority Banks shall have the right to appoint a successor Issuing Bank which shall be a commercial bank or trust company reasonably acceptable to the Parent.

(c) If a successor to a resigning Issuing Bank shall not have been so appointed within such 15 Business Day period, the resigning Issuing Bank, with the consent of the Parent (which consent will not be unreasonably withheld), shall have the right to then appoint a successor Issuing Bank who shall serve as Issuing Bank until such time, if any, as the Majority Banks appoint a successor Issuing Bank as provided above.

(d) If no successor Issuing Bank has been appointed pursuant to clause (b) or (c) above and shall have accepted such appointment by the 20th Business Day after the date such notice of resignation was given by the resigning Issuing Bank, the resigning Issuing Bank’s resignation shall become effective and no further Letters of Credit shall be issued hereunder until such time, if any, as the Majority Banks appoint a successor Issuing Bank as provided above.

SECTION 8.03. No Waiver; Remedies. No failure on the part of any Bank, the Issuing Bank or the Administrative Agent to exercise, and no delay in exercising, any right under any Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies provided in the Loan Documents are cumulative and not exclusive of any remedies provided by law.

SECTION 8.04. Costs, Expenses and Indemnity. (a) The Borrowers agree to pay on demand, (i) all reasonable costs and expenses of the Administrative Agent, the Syndication Agent, and the Joint Lead Arrangers in connection with the preparation, execution, delivery, administration, modification and amendment of the Loan Documents and the other documents to be delivered under the Loan Documents, including the reasonable fees and out-of-pocket expenses of counsel for the Administrative Agent with respect to preparation, execution and delivery of the Loan Documents and the satisfaction of the matters referred to in Section 3.01, and the reasonable costs and expenses of the Issuing Bank in connection with any Letter of Credit, and (ii) all reasonable legal and other costs and expenses, if any, of the Administrative Agent, the Issuing Bank and each Bank in connection with the enforcement (whether through negotiations, legal proceedings or otherwise) of the Loan Documents and the other documents to be delivered under the Loan Documents or incurred in connection with any workout, restructuring or bankruptcy.

-57-

(b) If any payment or purchase of principal of, or Conversion of, any LIBOR Advance or LIBOR Borrowing is made other than on the last day of an Interest Period relating to such Advance, as a result of a payment, purchase or Conversion pursuant to Section 2.07(f), 2.08, 2.09, 2.10, 2.11, 2.13, 2.16, or 2.19 or acceleration of the maturity of the Notes pursuant to Section 6.01 or for any other reason, the Borrowers shall, upon demand by any Bank (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Bank any amounts required to compensate such Bank for any additional losses, costs or expenses (other than taxes, which are dealt with in Section 2.13) which it may reasonably incur as a result of such payment, purchase or Conversion, including 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 or maintain such Advance.

(c) The Borrowers agree, to the fullest extent permitted by law, to indemnify and hold harmless the Administrative Agent, the Issuing Bank, the Joint Lead Arrangers, the Joint Book Managers, the Syndication Agent, the Co-Documentation Agents, each Bank and each other agent, arranger and manager and each of their respective directors, officers, employees and agents (collectively, “Indemnified Parties”) from and against any and all claims, damages, losses, liabilities and expenses (including reasonable fees and disbursements of counsel and claims, damages, losses, liabilities and expenses relating to environmental matters, but excluding taxes, which are dealt with in Section 2.13) (collectively, “Losses”) for which any of them may become liable or which may be incurred by or asserted against an Indemnified Party, in each case arising out of, related to or in connection with (i) any transaction in which any proceeds of all or any part of the Advances are applied, (ii) breach by a Borrower of any Loan Document, (iii) violation by the Parent or any of its Subsidiaries of any Environmental Law or any other law, rule, regulation or order, (iv) any Lien granted pursuant to any Loan Document, (v) ownership by any Indemnified Party of any property following foreclosure (or similar action) under any of the Loan Documents, to the extent such Losses arise out of or result from (x) any Hazardous Materials located in, on or under the property of the Parent or any Subsidiary on the date of such foreclosure (or similar action) or (y) operation of any such property on or before the date of such foreclosure (or similar action), including Losses which are imposed upon Persons under any Environmental Law solely by virtue of ownership, (vi) any Indemnified Party’s being deemed an operator of any property of the Parent or any of its Subsidiaries by a court or other Person, to the extent such Losses arise out of or result from any Hazardous Materials located in, on or under any such property, or (vii) any investigation, litigation, or proceeding, whether or not any Indemnified Party is a party thereto, related to or in connection with any of the foregoing or any Loan Document (EXPRESSLY INCLUDING ANY SUCH LOSSES ATTRIBUTABLE TO THE ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE OR STRICT LIABILITY OF SUCH INDEMNIFIED PARTY, BUT EXCLUDING ANY SUCH LOSSES ATTRIBUTABLE TO THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNIFIED PARTY). IT IS THE INTENT OF THE PARTIES HERETO THAT EACH INDEMNIFIED PARTY SHALL, TO THE EXTENT PROVIDED IN THIS SECTION 8.04(C), BE INDEMNIFIED FOR THEIR OWN ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE AND THEIR OWN STRICT LIABILITIES.

SECTION 8.05. Right of Set-Off. Upon (a) the occurrence and during the continuance of any Event of Default and (b) the making of the request or the granting of the consent specified by Section 6.01 to authorize the Administrative Agent to declare the Notes due and payable pursuant to the provisions of Section 6.01, each Bank 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 such Bank to or for the credit or the account of a Borrower against any and all of the obligations of such Borrower now or hereafter existing under this Agreement and the Note held by such Bank, irrespective of whether or not such Bank shall have made any demand under this Agreement or such Note and although such obligations may be unmatured. Each Bank agrees promptly to notify such 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 other rights of set-off) which such Bank may have.

SECTION 8.06. Assignments and Participations. (a) Each Bank may, in accordance with applicable law, assign to one or more banks or other entities all or a portion of its rights and obligations under this Agreement (including 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 (including the Letter of Credit Liabilities held by the assigning Bank pursuant to Section 2.18), (ii) except in the case of an assignment of all of a Bank’s rights and obligations under this Agreement, the sum 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 $10,000,000 (and in increments of $1,000,000 in excess thereof), (iii) each such assignment shall be to an Eligible Assignee, (iv) the Administrative Agent and, if no Event of Default exists, the Parent consent to such assignment (which consent shall not be unreasonably withheld), and (v) the parties to each such assignment shall execute and deliver to the Administrative Agent, for recording by the Administrative Agent in the Register, an Assignment and Acceptance, together with any Notes then held by such assigning Bank and any Notes then held by such assignee and a processing and recordation fee of $3,500. 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, (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 except that the rights under Sections 2.06, 2.10, 2.13 and 8.04 of such Bank shall continue with respect to

-59-

events and occurrences occurring before or concurrently with its ceasing to be a party hereto), and (z) unless the Parent in its sole discretion otherwise consents, no such assignee shall be entitled to receive any greater payment pursuant to Sections 2.06, 2.10 and 2.13 than the assigning Bank would have been entitled to receive with respect to the rights assigned to such assignee, except as a result of circumstances arising after the date of such assignment.

(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 any Borrower or any other Person or the performance or observance by any 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 financial statements referred to in Section 4.01(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 Administrative Agent, the Issuing Bank, 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 Administrative Agent to take such action as Administrative Agent on its behalf and to exercise such powers and discretion under the Loan Documents as are delegated to the Administrative Agent by the terms hereof or thereof, together with such powers and discretion as are reasonably incidental thereto; and (ix) 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 Administrative 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 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 Borrowers, the Administrative 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 Borrowers 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 any Notes then held by such assigning Bank and any Notes then held by such assignee, the Administrative Agent shall,

-60-

if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit C, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrowers. Within five Business Days after its receipt of such notice, an authorized officer of each Borrower shall execute and deliver to the Administrative Agent (i) in exchange for any surrendered Notes a new Note payable to the order of such Eligible Assignee (if a new Note is requested by such Eligible Assignee) in an amount equal to its Commitment after giving effect 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 (if an new Note is requested by the assigning Bank) in an amount equal to the Commitment retained by it hereunder (such new Notes, if any, shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Notes, if any, shall be dated the effective date of such Assignment and Acceptance, shall be properly completed and shall otherwise be in substantially the form of Exhibit A).

(e) Each Bank, in accordance with applicable law, may sell participations to one or more banks or other entities (other than the Parent or any of its Affiliates) in or to all or a portion of its rights and obligations under this Agreement (including all or a portion of any of its Commitments, the Advances owing to it and the Note held by it); provided that (i) such Bank’s obligations under this Agreement (including its Commitments to the Borrowers 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 Borrowers, the Administrative Agent, the Issuing Bank 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, (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 a 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, and (vi) unless the Parent in its sole discretion otherwise consents, no such participant shall be entitled to receive any greater payment pursuant to Sections 2.06, 2.10 and 2.13 than such Bank would have been entitled to receive with respect to the rights assigned to such participant by such Bank except as a result of circumstances arising after the date of such participation to the extent that such circumstances affect other Banks and participants generally, and (vii) each participant that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) shall provide to the Administrative Agent and the Parent a U.S. Internal Revenue Service Form W-8BEN or W-8ECI, as appropriate, or any successor form prescribed by the U.S. Internal Revenue Service, duly completed and certifying that such participant is fully exempt from United States withholding taxes with respect to all payments to be made to such participant under such participation agreement, or other documents satisfactory to the Parent and the Administrative Agent indicating that all payments to be made to such participant under such participation agreement are fully exempt from such withholding taxes, and neither the Borrowers nor the Administrative Agent shall have any obligation to pay to any participant any taxes, penalties, interest or other expenses, costs and losses incurred or payable by the Borrowers or the Administrative Agent as a result of the failure of such

-61-

participant to obtain such additional duly completed and signed copies of one or the other of such forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may be required under then-current United States law or regulations to avoid United States withholding taxes on payments in respect of all amounts to be received by such participant.

(f) Any Bank may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 8.06, disclose to the assignee or participant or proposed assignee or participant any information relating to the Borrowers or any of their Affiliates furnished to such Bank by or on behalf of the Borrowers or any of their Affiliates; provided, that, prior to any such disclosure, the assignee or participant or proposed assignee or participant shall agree to comply with Section 8.09.

(g) Notwithstanding any other provision set forth in this Agreement, any Bank may at any time (i) create a security interest in all or any portion of its rights under the Loan Documents (including the Advances owing to it and the Notes held by it) in favor of any Federal Reserve Bank in accordance with Regulation A of the Federal Reserve Board and (ii) upon notice to the Borrowers and the Administrative Agent, assign all or any portion of its rights and obligations under the Loan Documents to any of its Affiliates.

SECTION 8.07. Governing Law; Entire Agreement. This Agreement and the Notes shall be governed by, and construed in accordance with, the internal laws of the State of New York. This Agreement, the Notes, the other Loan Documents and any fee letter pertaining hereto accepted by the Parent constitute the entire understanding among the parties hereto with respect to the subject matter hereof and supersede any prior agreements, written or oral, with respect thereto.

SECTION 8.08. Interest. It is the intention of the parties hereto that the Administrative Agent, the Issuing Bank and each Bank shall conform strictly to usury laws applicable to it, if any. Accordingly, if the transactions with the Administrative Agent, the Issuing Bank or any Bank contemplated hereby would be usurious under applicable law, if any, then, in that event, notwithstanding anything to the contrary in the Notes, this Agreement or any other agreement entered into in connection with this Agreement or the Notes, it is agreed as follows: (a) the aggregate of all consideration which constitutes interest under applicable law that is contracted for, taken, reserved, charged or received by the Administrative Agent, the Issuing Bank or such Bank, as the case may be, under the Notes, this Agreement or under any other agreement entered into in connection with this Agreement or the Notes shall under no circumstances exceed the maximum amount allowed by such applicable law and any excess shall be cancelled automatically and, if theretofore paid, shall at the option of the Administrative Agent, the Issuing Bank or such Bank, as the case may be, be applied on the principal amount of the obligations owed to the Administrative Agent, the Issuing Bank or such Bank, as the case may be, by the Borrowers or refunded by the Administrative Agent, the Issuing Bank or such Bank, as the case may be, to the applicable Borrower, and (b) in the event that the maturity of any Note or other obligation payable to the Administrative Agent, the Issuing Bank or such Bank, as the case may be, is accelerated or in the event of any permitted prepayment, then such consideration that constitutes interest under law applicable to the Administrative Agent, the Issuing Bank or such Bank, as the case may be, may never include more than the maximum amount allowed by such applicable law and excess interest, if any, to the Administrative Agent, the Issuing Bank or such Bank, as the case may be,

-62-
