INTRODUCTION

Wisconsin Energy Corporation is a diversified holding company which conducts its operations primarily in two operating segments: a utility energy segment and a non-utility energy segment. Unless qualified by their context when used in this document, the terms Wisconsin Energy, the Company, our, us or we refer to the holding company and all of its subsidiaries. Our primary subsidiaries are Wisconsin Electric Power Company (Wisconsin Electric), Wisconsin Gas LLC (Wisconsin Gas) and W.E. Power, LLC (We Power).

Utility Energy Segment:   Our utility energy segment consists of: Wisconsin Electric, which serves electric customers in Wisconsin and the Upper Peninsula of Michigan, gas customers in Wisconsin and steam customers in metro Milwaukee, Wisconsin; Wisconsin Gas, which serves gas customers in Wisconsin and water customers in suburban Milwaukee, Wisconsin; and Edison Sault Electric Company (Edison Sault), which serves electric customers in the Upper Peninsula of Michigan. Wisconsin Electric and Wisconsin Gas operate under the trade name of "We Energies".

Non-Utility Energy Segment:   Our non-utility energy segment primarily consists of We Power. We Power was formed in 2001 to construct, own, and lease to Wisconsin Electric the new generating capacity included in our Power the Future strategy, which is described further in this report.

Other:   Other non-utility operating subsidiaries of Wisconsin Energy primarily includes Wispark LLC (Wispark), which has $93.8 million of assets and develops and invests in real estate.

Discontinued Operations:   Effective May 31, 2005, we sold our Calumet Energy (Calumet) facility, which was part of our non-utility energy segment. In August 2005, we announced our intent to sell Minergy Neenah, LLC (Minergy Neenah).

We have prepared the unaudited interim financial statements presented in this Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). We have condensed or omitted some information and note disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles pursuant to these rules and regulations. This Form 10-Q, including the financial statements contained herein, should be read in conjunction with our 2005 Annual Report on Form 10-K, including the financial statements and notes therein.

WISCONSIN ENERGY CORPORATION
NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
(Unaudited)

 1 -- GENERAL INFORMATION

Our accompanying unaudited consolidated condensed financial statements should be read in conjunction with Item 8, Financial Statements and Supplementary Data, in our 2005 Annual Report on Form 10-K. In the opinion of management, we have included all adjustments, normal and recurring in nature, necessary to a fair presentation of the results of operations, cash flows and financial position in the accompanying income statements, statements of cash flows and balance sheets. The results of operations for the three months ended March 31, 2006 are not necessarily indicative of the results which may be expected for the entire fiscal year 2006 because of seasonal and other factors.

Modifications to Prior Statements:   We have modified certain income statement and cash flows presentations. Prior year financial statement amounts have been reclassified to conform to their current year presentation. These reporting changes had no impact on total earnings per share or cash provided, or used in, operating, investing or financing activities.

The most significant reclassifications relate to the reporting of discontinued operations pursuant to Statement of Financial Accounting Standards (SFAS) 144, Accounting for the Impairment or Disposal of Long-Lived Assets. Previously, these were included as components of continuing operations. Prior year financial statement amounts have been reclassified to conform to their current year presentation. These reclassifications had no effect on total earnings per share.

We have changed the presentation of the investing activities within our nuclear decommissioning trusts on the accompanying Consolidated Condensed Statements of Cash Flows to present proceeds from investments within the nuclear decommissioning trusts and purchases of investments within the nuclear decommissioning trusts. Previously, these items were excluded from the Consolidated Statements of Cash Flows as the nuclear decommissioning trusts are considered restricted investments. This reporting change had no impact to net cash provided by, or used in, operating, investing or financing activities.

Interim Accounting for Electric Fuel Revenues:   For 2006, Wisconsin Electric will have to refund to customers any electric fuel revenues that it receives that are in excess of fuel costs that it incurs, as defined by the Wisconsin fuel rules. We do not recognize revenue for any amounts that are currently billable if it is probable that we will refund those amounts to customers.

 2 -- POWER THE FUTURE ACCOUNTING MATTERS

In July 2005, the first unit at Port Washington Generating Station (PWGS) was placed in service. This asset has a cost of approximately $364.3 million which includes approximately $31.1 million of capitalized interest. The asset will be depreciated over its estimated useful life of approximately 37 years. The cost of the plant, plus a return, is expected to be recovered through Wisconsin Electric's rates over a 25 year period at an annual amount of approximately $48 million.

We capitalize interest expense during the construction of our Power the Future power plants. For the three months ended March 31, 2006 and 2005, we capitalized $6.0 million and $7.0 million of interest costs at an average rate of 6.7% and 6.5%.

7

Under the lease agreements associated with our Power the Future plants, we are able to recover from utility customers the carrying costs associated with the construction of these power plants. We defer these carrying costs on our balance sheet and they will be amortized to revenue over the individual lease term. For the three months ended March 31, 2006 and 2005, we deferred $13.8 million and $16.0 million of carrying costs associated with the Power the Future plants.

 3 -- DISCONTINUED OPERATIONS AND ASSETS HELD FOR SALE

The earnings of the assets identified below are reflected in discontinued operations in the accompanying Consolidated Condensed Income Statements. The combined operating revenues for these items were approximately $5 million for the three months ended March 31, 2006 and 2005.

Minergy Neenah:   In August 2005, we announced our intent to sell Minergy Neenah. The primary assets of Minergy Neenah are the Glass Aggregate plant and related operating contracts. The plant recycles paper sludge from paper mills into electricity, steam and a glass aggregate product.

The largest source of revenue for Minergy Neenah is from a long-term steam contract with a nearby paper mill owned by P.H. Glatfelter Company (Glatfelter). In February 2006, Glatfelter announced that it expected to permanently close the mill as of June 30, 2006. Minergy Neenah is owed a termination fee if the mill is closed. We are currently evaluating the operating and financial impacts to Minergy Neenah when the paper mill is shut down. We are continuing our effort to sell Minergy Neenah and absent a sale are evaluating closure of our plant. We do not expect the loss of this revenue stream, a sale or our plant closure to have a material financial impact on Wisconsin Energy as we have previously recorded impairment charges on this asset to reflect an expected realizable value.

Wisvest - Calumet:   Effective May 31, 2005, we sold our Calumet Energy (Calumet) facility for approximately $37.0 million in cash to Tenaska Power Fund, L.P. (Tenaska). The primary assets of Calumet were a 308-megawatt natural gas-fired peaking power facility in Chicago, Illinois and related operating contracts. This transaction generated a gain on sale of approximately $4.7 million and approximately $32.0 million in cash tax benefits.

 4 -- COMMON EQUITY

Comprehensive Income:   Comprehensive income includes all changes in equity during a period except those resulting from investments by and distributions to owners. We recorded the following total comprehensive income during the three months ended March 31, 2006 and 2005:

	Three Months Ended March 31
Comprehensive Income	2006	2005
	(Millions of Dollars)
Net Income	$105.7	$89.9
Other Comprehensive Income
Hedging	0.2	1.0
Total Other Comprehensive Income	0.2	1.0
Total Comprehensive Income	$105.9	$90.9

Share-Based Compensation Plans:   Effective January 1, 2006, we adopted SFAS 123R, Share-Based Payment, using the modified prospective method and using a binomial pricing model to estimate the fair value of stock options granted subsequent to December 31, 2005. Prior to January 1, 2006, we accounted for share based compensation under Accounting Principles Board Opinion 25 (APB 25), Accounting for

8
Stock Issued to Employees, and we disclosed the pro forma impact of share based compensation expense under SFAS 123, Accounting for Stock-Based Compensation. Historically, all stock options have been granted with an exercise price equal to the fair market value of the common stock on the date of grant. Accordingly, no compensation expense was recognized in connection with option grants.

We utilize the straight-line attribution method for recognizing stock-based compensation expense under SFAS 123R and recorded $1.1 million or approximately $0.01 per share of compensation expense, net of tax, in the first quarter of 2006 for stock option awards made to our employees and directors.

Results for the first quarter of 2005 have not been restated. Had compensation expense for employee stock options been determined based on fair value at the grant date consistent with SFAS 123R, our net income and earnings per share for the first quarter of 2005 would have been reduced to the pro forma amounts indicated below.

	Three Months Ended March 31, 2005
	(Millions of Dollars)
Net Income
As reported	$89.9
Add: Stock-based employee compensation expense included in           reported net income, net of related tax effects	0.4
Deduct: Total stock-based employee compensation expense           determined under fair value based method for all awards, net           of related tax effects	0.9
Pro forma	$89.4

Earnings Per Common Share	Basic	Diluted
As reported	$0.77	$0.76
Pro forma	$0.76	$0.76

In the first quarter of 2006, the Compensation Committee of the Board of Directors granted 1,292,275 options that had an estimated fair value of $7.55 per share using a binomial option-pricing model. In the first quarter of 2005, the Compensation Committee of the Board of Directors granted 1,328,966 options that had an estimated fair value of $8.32 per share using the Black-Scholes model. The following assumptions were used to value the options:

	Three Months Ended
	March 31, 2006	March 31, 2005
Risk free interest rate	4.3% - 4.4%	4.4%
Dividend yield	2.4%	2.5%
Expected volatility	17% - 20%	19%
Expected life (years)	6.31	10

The risk-free interest rate is based on the U.S. Treasury interest rate whose term is consistent with the expected life of the stock options. Dividend yield, expected volatility and expected life assumptions, for 2006, are based on our historical experience.

Our 1993 Omnibus Stock Incentive Plan, as amended (OSIP), as approved by stockholders, enables us to provide a long-term incentive through equity interests in Wisconsin Energy, to outside directors, selected officers and key employees of the Company. The OSIP provides for the granting of stock options, stock

9
appreciation rights, stock awards and performance shares. Awards may be paid in common stock, cash or a combination thereof.

The exercise price of a stock option under the OSIP is to be no less than 100% of the common stock's fair market value on the grant date and options may not be exercised within six months of the grant date except in the event of a change in control. In December 2004, the Compensation Committee of the Board of Directors approved the acceleration of vesting of all unvested options awarded to executive officers and other key employees in 2002, 2003 and 2004. Options granted subsequent to January 1, 2005 are non-qualified stock options which vest on a cliff-basis after a three year period. Generally, options expire no later than ten years from the date of grant.

The following is a summary of our stock option activity through March 31, 2006.

Stock Options	Number of Options	Weighted-Average Exercise Price	Weighted Average Remaining Contractual Life (years)
Outstanding at January 1, 2006	7,569,619	$28.10
Granted	1,292,275	$39.48
Exercised	(250,786)	$22.34
Forfeited	--	$   --
Outstanding at March 31, 2006	8,611,108	$29.97	7.2

The aggregate intrinsic value of stock options exercised during the quarter ended March 31, 2006 was approximately $4.5 million.

The following table summarizes information about stock options outstanding at March 31, 2006:

	Options Outstanding			Options Exercisable
Range of Exercise Prices	Number	Weighted -Average Exercise Price	Life (years)	Number	Weighted-Average Exercise Price	Life (years)
$10.86  to  $19.97	339,583	$18.60	3.6	339,583	$18.60	3.6
$20.39  to  $23.05	1,483,465	$21.99	5.4	1,483,465	$21.99	5.4
$25.31  to  $27.65	1,881,109	$25.73	6.1	1,860,555	$25.73	6.1

	8,611,108	$29.97	7.2	5,977,829	$27.00	6.2
	(Millions)			(Millions)
Aggregate Intrinsic Value	$86.2			$77.6

The following table summarizes the status of our non-vested options since December 31, 2005:

Non-Vested Stock Options	Number of Options	Weighted- Average Fair Value
Non-vested at January 1, 2006	1,360,153	$8.30
Granted	1,292,275	$7.55
Vested	(19,149)	$7.39
Forfeited	--	$   --
Non-vested at March 31, 2006	2,633,279	$7.94

The total fair value of options vesting during the three months ended March 31, 2006 was approximately $0.1 million. As of March 31, 2006, there was approximately $14.7 million of total unrecognized compensation expense related to non-vested share based compensation.

The Compensation Committee has also approved restricted stock grants to certain key employees and directors. The following restricted stock activity occurred during the three months ended March 31, 2006:

Restricted Shares	Number of Shares	Weighted- Average Market Price
Outstanding at January 1, 2006	193,657
Granted	17,323	$39.43
Released / Forfeited	--	$   --
Outstanding at March 31, 2006	210,980

Recipients of the restricted shares, who have the right to vote the shares and to receive dividends, are not required to provide consideration to us other than rendering service. Forfeiture provisions on the restricted stock generally expire 10 years after award grant subject to an accelerated expiration schedule based on the achievement of certain financial performance goals.

We record the market value of the restricted stock awards on the date of grant and then we charge their value to expense over the vesting period of the awards. We also adjust expense for acceleration of vesting due to achievement of performance goals.

In January 2004, the Compensation Committee granted 159,159 performance shares to officers and other key employees. In January 2006 and 2005 the Compensation Committee granted 150,281 and 101,834 performance units to officers and other key employees under the Wisconsin Energy Performance Unit Plan. Under the grants, the ultimate number of shares of our common stock or cash which will be awarded is dependent upon the achievement of certain financial performance of our stock over a three year period. Under the terms of the award, participants may earn between 0% and 175% of the base performance award. We are accruing compensation costs over the three year period based on our estimate of the final expected value of the award. The 2004 grant will be settled in common stock. The 2005 and 2006 grants will be settled in cash.

Common Stock Activity:   No new shares of common stock were issued during the three months ended March 31, 2006. During the first three months of 2006, we received proceeds of $5.7 million related to the exercise of stock options, compared with $18.9 million during the same period in 2005. We instructed our plan agent to purchase common stock in the open market at a cost of $10.2 million to fulfill the exercised stock options in the first quarter of 2006, compared with $29.8 million during the

11
same period in 2005. This cost is included in purchase of common stock on our Consolidated Condensed Statements of Cash Flows.

 5 -- ASSET RETIREMENT OBLIGATIONS

Our asset retirement obligations under SFAS 143, Accounting for Asset Retirement Obligations, primarily relate to the future decommissioning costs for our Point Beach Nuclear Plant (Point Beach) and to asbestos related removal costs associated with other power plants. Our asset retirement obligations at March 31, 2006 were $360.0 million.

We adopted FASB Interpretation 47 (FIN 47), Accounting for Conditional Asset Retirement Obligations, an interpretation of SFAS 143, effective December 31, 2005. FIN 47 defines a conditional asset retirement obligation as a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the entity. The adoption of FIN 47 had no effect on net income due to the regulatory treatment of asset retirement costs.

If we had adopted interpretation FIN 47 at the beginning of fiscal 2005, we would have reported the following asset retirement obligations on our Consolidated Condensed Balance Sheets in "Asset Retirement Obligations" as of March 31:

Asset Retirement Obligations	2006	2005
	(Millions of Dollars)
Reported (a)	$360.0	$765.6
Pro forma	$360.0	$802.4

(a) The 2005 reported balance represents the liability recorded under SFAS 143, which is primarily related to nuclear decommissioning costs.

We follow SFAS 133, Accounting for Derivative Instruments and Hedging Activities, as amended by SFAS 149, an amendment of SFAS 133 on Derivative Instruments and Hedging Activities, which requires that every derivative instrument be recorded on the balance sheet as an asset or liability measured at its fair value and that changes in the derivative's fair value be recognized currently in earnings unless specific hedge accounting criteria are met. For most energy related physical and financial contracts in our regulated operations that qualify as derivatives under SFAS 133, the Public Service Commission of Wisconsin (PSCW) allows the effects of the fair market value accounting to be offset to regulatory assets and liabilities.

 7 -- BENEFITS

The components of our net periodic pension and other post-retirement benefit costs for the three months ended March 31, 2006 and 2005 were as follows:

	Pension Benefits		Other Post-Retirement Benefits
	2006	2005	2006	2005
	(Millions of Dollars)
Net Periodic Benefit Cost
Service cost	$9.1	$8.9	$3.4	$2.8
Interest cost	17.4	17.7	4.6	5.2
Expected return on plan assets	(20.2)	(21.4)	(3.7)	(1.9)
Amortization of:
Transition (asset) obligation	-	(0.1)	-	-
Prior service cost	1.3	1.3	(3.4)	0.1
Actuarial loss	6.1	4.3	2.4	2.0
Net Periodic Benefit Cost	$13.7	$10.7	$3.3	$8.2

Employee Benefit Plans and Post-retirement Benefits:   In October 2005, we announced that we were offering to our retirees a Medicare Advantage program as an option within our existing post-retirement medical and drug plans. The Medicare Advantage program is part of the Medicare Prescription Drug, Improvement and Modernization Act of 2003. The program offers post-65 medical and drug benefits through private insurance carriers. The Medicare Advantage program is expected to reduce the cost of post-65 medical and drug costs for our retirees and us. Due to this change, we remeasured the fair value of our other post-retirement plans in the fourth quarter of 2005 in accordance with SFAS 106, Employer's Accounting for Post-Retirement Benefits Other than Pensions. As a result of the Medicare Advantage program, our 2006 post-retirement costs for the three months ended March 31, 2006 are less than our 2005 costs in the comparative period.

8 -- GUARANTEES

We enter into various guarantees to provide financial and performance assurance to third parties on behalf of affiliates. As of March 31, 2006, we had the following guarantees:

	Maximum Potential Future Payments	Outstanding at March 31, 2006	Liability Recorded at March 31, 2006

10 -- COMMITMENTS AND CONTINGENCIES

Environmental Matters:   We periodically review our exposure for remediation costs as evidence becomes available indicating that our remediation liability has changed. Based on current information, we believe that future costs in excess of the amounts accrued and/or disclosed on all presently known and quantifiable environmental contingencies will not be material to our financial position or results of operations.

WICOR Manufacturing:   Effective July 31, 2004, we sold our manufacturing business. Pursuant to the terms of the sales agreement, Wisconsin Energy agreed to customary indemnification provisions related to certain environmental, asbestos and product liability matters associated with the manufacturing business. In addition, the amount of cash taxes and future deferred income tax benefits are subject to a number of factors including appraisals and applicable tax laws. We have established reserves related to the indemnification and tax matters.

Wisvest - Calumet:   Pursuant to the terms of the sales agreement, Wisvest has agreed to customary indemnification provisions related to environmental conditions and other matters. Except for retention of the full exposure to indemnify Tenaska for environmental claims related to certain property no longer leased or owned by Wisvest or any of its subsidiaries, Wisvest's maximum aggregate exposure under the indemnification provisions is $35 million. Pursuant to the terms of the agreement, we have guaranteed post-closing obligations under the agreement, including indemnity obligations.

(a) As measured at Mitchell International Airport in Milwaukee, Wisconsin. Normal degree days are based upon a twenty-year moving average.

Our electric utility operating revenues increased by $85.8 million, or 16.4%, when compared to the first quarter of 2005. We estimate that our first quarter 2006 revenues were $72.5 million higher than the first quarter of 2005 due to pricing increases that we received during 2005 and in January 2006. The most significant increases authorized by the PSCW were to recover higher fuel and purchased power costs, capital costs associated with the new plants under our Power the Future plan, and increased transmission costs. For more information on the pricing increases, see Utility Rates and Regulatory Matters in Factors Affecting Results, Liquidity and Capital Resources below.

Our electric sales volumes increased by 1.6 % as compared to the same period last year. Sales volumes to other utilities during the first three months of 2006 were approximately five times greater than the same period in 2005. The increase in sale volumes to other utilities is attributed to the availability of Unit 1 at PWGS, which provided additional generation capacity. PWGS Unit 1 was not operational until the third quarter of 2005. Residential sales volumes were flat due to milder winter weather as heating degree days were approximately 10.7% lower than the prior year. Sales volumes in the Other Retail/Municipal class decreased approximately 17.3% compared to the prior year due, in part, to the expiration of a wholesale contract on December 31, 2005.

Fuel and Purchased Power

Our fuel and purchased power expenses increased by $11.2 million, or 7.0%, when compared to the first quarter of 2005. The increase was due, in part, to the following: (1) the average cost of purchased power and natural gas-fired units was approximately 9.1% higher in the first quarter of 2006 as compared to the same period in 2005 and (2) the cost of coal, including transportation, rose 17.6% when compared to last year. These increases were partially offset by increased generation from our lower cost base-load coal units which generated approximately 5.7% more megawatt-hours in the first quarter of 2006 as compared to the same period in 2005. The increased coal unit output reduced the need for higher cost purchased power and gas-fired generation.

17

The recovery of our fuel and purchased power costs (fuel costs) in Wisconsin is governed by rules established by the PSCW. For 2006, if our annual fuel recoveries exceed our annual fuel costs, as defined by the PSCW, then we will have to refund the excess fuel recoveries. If we under-collect our fuel costs by more than 2% on an annual basis, we have an opportunity to seek a rate increase prospectively. For the first quarter of 2006, we over-collected fuel costs by approximately $28.5 million; however, on an annual basis, we project that we will under-recover our annual fuel costs in the range of approximately $0.0 to $10.0 million. For the first quarter of 2005, we under-collected our fuel costs by $11.1 million and, on an annual basis, we under-collected our fuel costs by $35.6 million. When comparing the results of our first quarter 2006 with 2005, we saw a $39.6 million improvement in the collection of fuel costs.

Gas Utility Revenues, Gross Margin and Therm Deliveries

A comparison follows of gas utility operating revenues, gross margin and gas deliveries during the first quarter of 2006 with similar information for the first quarter of 2005. We believe gross margin is a better performance indicator than revenues because changes in the cost of gas sold flow through to revenue under gas cost recovery mechanisms. Between the comparative periods, total gas operating revenues increased by $67.8 million or 12.1%.

	Three Months Ended March 31
Gas Utility Operations	2006	B (W)	2005
	(Millions of Dollars)
Gas Operating Revenues	$627.9	$67.8	$560.1

Heating (3,251 Normal)				2,935	(353)	3,288

(a) As measured at Mitchell International Airport in Milwaukee, Wisconsin. Normal degree days are based upon a twenty-year moving average.

Our gas utility gross margin decreased by $1.9 million when compared to the first quarter of 2005 due to a decline in gas sales volumes that was driven by mild winter weather and by lower customer usage. The winter temperatures (as measured by heating degree days) were approximately 10.7% warmer than the first quarter in 2005. The mild winter weather reduced customer demand for heating. In addition, with the increase in natural gas prices, we have experienced a reduction in the normalized use of gas per

18
customer. The decline in sales volumes was partially offset by pricing increases that were granted by the PSCW and implemented in January 2006. The gas pricing increases were primarily granted to recover increased operating costs, including bad debt expenses. Our margins increased between the comparative periods by approximately $15.0 million due to these pricing increases. We anticipate that the 2006 annual impact of the rate increase for our gas margins would be approximately $53.5 million under normal customer usage; however, we believe that the actual amount will be lower due to reduced customer usage.

Other Operation and Maintenance Expenses

Our other operation and maintenance expenses increased by $55.9 million, or 22.3%, when compared to the first quarter of 2005. As discussed above, we received pricing increases during 2005 and in January 2006 to cover increased costs. Our increases in other operation and maintenance expenses that relate to the pricing increases include increased Power the Future lease costs of $25.1 million, increased transmission expenses of $13.0 million and increased bad debt expenses of $3.9 million. In addition, other operation and maintenance expenses increased approximately $5.3 million due to PWGS operating costs and the timing of scheduled outages and maintenance projects at our plants.

Depreciation, Decommissioning and Amortization

Depreciation, Decommissioning and Amortization expenses decreased by $0.7 million or 0.1% when compared to the first quarter of 2005. In January 2006, we implemented new depreciation rates approved by the PSCW which reduced annual depreciation expenses. The decline was offset by increased depreciation expenses on plant additions.

NON-UTILITY ENERGY SEGMENT CONTRIBUTION TO OPERATING INCOME

The most significant subsidiary in this segment is We Power. This segment includes the revenues billed to Wisconsin Electric for PWGS Unit 1 and it also includes the depreciation expense related to Unit 1.

Our non-utility energy segment contributed $9.1 million of operating income for the first quarter 2006 as compared to an operating loss of $1.0 million for the first quarter of 2005. This increase in operating income reflects a full quarter of the operating income for PWGS Unit 1, which was placed in service in July 2005. There were no earnings associated with this unit in the first quarter of 2005.

CORPORATE AND OTHER CONTRIBUTION TO OPERATING INCOME

Corporate and other affiliates had an operating loss of $3.0 million in the first quarter of 2006 compared with an operating loss of $2.8 million in the same period in 2005. The increase in operating loss is attributable to lower operating earnings at Wispark.

CONSOLIDATED OTHER INCOME, NET

Other income, net increased by $3.2 million when compared to the first quarter of 2005. The increase primarily reflects increased carrying costs on regulatory assets of $2.1 million as well as an increase in Allowance for Funds used During Construction (AFUDC) of $1.9 million due to a higher average balance of AFUDC-qualifying utility construction projects between the comparative periods.

19

CONSOLIDATED INTEREST EXPENSE

Interest expense increased by $2.8 million in the three months ended March 31, 2006 when compared with the same period in 2005. This increase reflects higher debt levels and higher short-term interest rates. In addition, in the first quarter of 2005, we expensed approximately $3.0 million related to the amortization of costs associated with prior debt redemptions. These costs were fully amortized as of July 2005; therefore, there were no similar expenses in the first quarter of 2006.

CONSOLIDATED INCOME TAXES

For the first quarter of 2006, our effective tax rate applicable to continuing operations was 37.6% compared to 36.7% for the first quarter of 2005. We expect our 2006 annual effective tax rate to be between 37.5% and 38.5%.

DISCONTINUED OPERATIONS

Income from discontinued operations for the first quarter of 2006 was $1.3 million compared to a loss from discontinued operations of $0.1 million in the first quarter of 2005. Discontinued operations primarily include the operations of Minergy Neenah. In the first quarter of 2005, the operations of Wisvest-Calumet, which was sold effective May 31, 2005, were classified as discontinued operations.

LIQUIDITY AND CAPITAL RESOURCES

CASH FLOWS

The following summarizes our cash flows from continuing operations during the first three months of 2006 and 2005:

	Three Months Ended March 31
Wisconsin Energy Corporation	2006	2005
	(Millions of Dollars)
Cash Provided by (Used in)
Operating Activities	$339.7	$376.7
Investing Activities	($214.2)	($163.0)
Financing Activities	($161.6)	($230.8)

Operating Activities

Cash provided by operating activities decreased to $339.7 million during the first three months of 2006 compared with $376.7 million during the same period in 2005. This decrease was partially due to lower than expected withdrawal of natural gas in storage due to the mild weather, and increased accounts receivable balances, offset in part, by higher cash earnings between the comparative periods.

Investing Activities

During the first three months of 2006, cash used in investing activities was $214.2 million, an increase of $51.2 million over the same period in 2005. This increase was due primarily to increased capital

20
expenditures at We Power related to our Power the Future plan and increased spending on reliability capital projects at the regulated utility.

Financing Activities

During the three months ended March 31, 2006, we used $161.6 million for financing activities compared with using $230.8 million for financing activities during the first three months of 2005. The primary uses of cash during the first three months of 2006 and 2005 were to reduce short-term debt and to pay dividends on common stock.

In the first quarter of 2006, we received proceeds of $5.7 million related to the exercise of stock options, compared with $18.9 million in the first quarter of 2005. Instead of issuing new shares for these stock options, we instructed our plan agent to purchase common stock in the open market at a cost of $10.2 million, compared with $29.8 million in the first quarter of 2005. This cost is included in Purchase of common stock on our Consolidated Condensed Statements of Cash Flows.

CAPITAL RESOURCES AND REQUIREMENTS

Capital Resources

We anticipate meeting our capital requirements during the remaining nine months of 2006 primarily through internally generated funds and short-term borrowings, supplemented by the issuance of intermediate or long-term debt securities depending on market conditions and other factors. Beyond 2006, we anticipate meeting our capital requirements through internally generated funds supplemented, when required, by the issuance of debt securities.

We have access to the capital markets and have been able to generate funds internally and externally to meet our capital requirements. Our ability to attract the necessary financial capital at reasonable terms is critical to our overall strategic plan. We believe that we have adequate capacity to fund our operations for the foreseeable future through our borrowing arrangements and internally generated cash.

We are currently evaluating the possible issuance of environmental trust bonds in the fourth quarter of 2006 or the first quarter of 2007. The proposed terms of the bonds are subject to further PSCW approval prior to issuance. Environmental trust bonds give utilities the ability to securitize the portion of customer bills that recovers the cost of certain investments intended to improve the environment. The measure is expected to result in a lower cost to customers when compared to traditional financing and ratemaking.

Wisconsin Energy, Wisconsin Electric and Wisconsin Gas credit agreements provide liquidity support for each company's obligations with respect to commercial paper and for general corporate purposes.

As of March 31, 2006, we had approximately $1.4 billion of available unused lines of bank back-up credit facilities on a consolidated basis and approximately $345.5 million of total consolidated short-term debt outstanding.

We review our bank back-up credit facility needs on an ongoing basis and expect to be able to maintain adequate credit facilities to support our operations. The following table summarizes such facilities at March 31, 2006:

21

Company	Total Facility	Letters of Credit	Credit Available	Facility Expiration	Facility Term
	(Millions of Dollars)
Wisconsin Energy	$300.0	$  -	$300.0	June-2007	3 year
Wisconsin Energy	$300.0	$1.8	$298.2	Apr-2006	3 year
Wisconsin Electric	$500.0	$2.0	$498.0	Mar-2011	5 year
Wisconsin Gas	$300.0	$  -	$300.0	Mar-2011	5 year

On March 30, 2006, Wisconsin Electric entered into an unsecured five year $500 million bank back-up credit facility to replace a $250 million three year credit facility with an expiration date of June 2007 and a $125 million three year credit facility with an expiration date of November 2007. This new facility will expire in March 2011 with a renewal provision for two one-year extensions, subject to lender approval.

On March 30, 2006, Wisconsin Gas entered into an unsecured five year $300 million bank back-up credit facility to replace a $200 million three year credit facility with an expiration date of June 2007. This new facility will expire in March 2011 with a renewal provision for two one-year extensions, subject to lender approval.

On April 6, 2006, Wisconsin Energy entered into an unsecured five year $900 million bank back-upcredit facility to replace a $300 million credit facility that would have expired on April 8, 2006 and a $300 million credit facility with an expiration date of June 2007. This new credit facility will expire in April 2011 with a renewal provision for two one-year extensions, subject to lender approval.

The following table shows our consolidated capitalization structure at March 31, 2006 and at December 31, 2005:

Capitalization Structure	March 31, 2006		December 31, 2005
	(Millions of Dollars)
Common Equity	$2,758.5	41.5%	$2,680.1	40.0%

Long-Term Debt (including
current maturities)	3,507.6	52.8%	3,527.0	52.7%
Short-Term Debt	345.5	5.2%	456.3	6.8%
Total	$6,642.0	100.0%	$6,693.8	100.0%
Ratio of Debt to Total Capital		58.0%		59.5%

Access to capital markets at a reasonable cost is determined in large part by credit quality. The following table summarizes the ratings of our debt securities and the debt securities and preferred stock of our subsidiaries by Standard & Poors Corporation (S&P), Moody's Investors Service (Moody's) and Fitch Ratings (Fitch) as of March 31, 2006.

On March 29, 2005, S&P affirmed the security ratings of Wisconsin Energy, Wisconsin Electric and Wisconsin Gas and changed the security ratings outlook from stable to negative for all three companies. The security rating outlooks assigned by Moody's and Fitch for Wisconsin Energy, Wisconsin Electric, Wisconsin Gas and Wisconsin Energy Capital Corporation are all stable.

We believe these security ratings should provide a significant degree of flexibility in obtaining funds on competitive terms. However, these security ratings reflect the views of the rating agencies only. An explanation of the significance of these ratings may be obtained from each rating agency. Such ratings are not a recommendation to buy, sell or hold securities, but rather an indication of creditworthiness. Any rating can be revised upward or downward or withdrawn at any time by a rating agency if it decides that the circumstances warrant the change. Each rating should be evaluated independently of any other rating.

Capital Requirements

Capital requirements during the remainder of 2006 are expected to be principally for capital expenditures, to satisfy long-term debt maturities and nuclear fuel. Our 2006 annual consolidated capital expenditure budget, excluding the purchase of nuclear fuel, is approximately $1,020.0 million.

Off-Balance Sheet Arrangements:   We are a party to various financial instruments with off-balance sheet risk as a part of our normal course of business, including financial guarantees and letters of credit which support construction projects, commodity contracts and other payment obligations. We continue to believe that these agreements do not have, and are not reasonably likely to have, a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to our investors. For further information, see Note 8 -- Guarantees in the Notes to Consolidated Condensed Financial Statements in this report for more information.

We have identified three tolling and purchased power agreements with third parties but have been unable to determine if we are the primary beneficiary of any of these three variable interest entities as defined by FASB Interpretation 46, Consolidation of Variable Interest Entities (FIN 46). As a result, we do not consolidate these entities. Instead, we account for one of these contracts as a capital lease and for the other two contracts as operating leases. For additional information, see Note G -- Variable Interest Entities in our 2005 Annual Report on Form 10-K. We have included our contractual obligations under

23
all three of these contracts in our evaluation of Contractual Obligations/Commercial Commitments discussed below.

Contractual Obligations/Commercial Commitments:   Our total contractual obligations and other commercial commitments are approximately $9.4 billion as of March 31, 2006 compared with $9.6 billion as of December 31, 2005. Our total contractual obligations and other commercial commitments as of March 31, 2006 decreased compared with December 31, 2005 due primarily to periodic payments related to these types of obligations which were greater than new commitments made in the ordinary course of business during the quarter.

FACTORS AFFECTING RESULTS, LIQUDITY AND CAPITAL RESOURCES

The following is a discussion of certain factors that may affect our results of operations, liquidity and capital resources. The following discussion should be read together with the information under the heading "Factors Affecting Results, Liquidity and Capital Resources" in Item 7 of our 2005 Annual Report on Form 10-K, which provides a more complete discussion of factors affecting us, including market risks and other significant risks, our Power the Future strategy, utility rates and regulatory matters, electric system reliability, environmental matters, legal matters, nuclear operations, industry restructuring and competition and other matters.

MARKET RISKS AND OTHER SIGNIFICANT RISKS

Credit Rating Risk:   We do not have any credit agreements that would require material changes in payment schedules or terminations as a result of a credit rating downgrade. We do have certain agreements in the form of commodity and energy services contracts and employee benefit plans that could require, in the event of a credit ratings change to below investment grade, a termination payment if collateral is not provided or an accelerated payment. At March 31, 2006, we estimate that the potential payments under these agreements that could result from credit rating downgrades totaled approximately $72.7 million.

POWER THE FUTURE

Under our Power the Future strategy, we expect to meet a significant portion of our future generation needs through the construction of the PWGS and Oak Creek expansion by We Power. The new plants will be leased by We Power to Wisconsin Electric under long-term leases, and we expect Wisconsin Electric to recover the lease payments in its electric rates. See Factors Affecting Results, Liquidity and Capital Resources -- Power the Future in Item 7 of our 2005 Annual Report on Form 10-K for additional information on Power the Future.

Port Washington:   In July 2005, the first unit at PWGS became operational. Construction of the second gas-fired unit is well underway. Site preparation, including removal of the old coal units at the site, was completed early this year, and most of the major components have been procured for the second unit at PWGS. The unit is expected to begin commercial operation in time for the peak summer season in 2008.

Oak Creek Expansion:   In November 2003, the PSCW issued an order granting Wisconsin Energy, Wisconsin Electric and We Power a Certificate of Public Convenience and Necessity (CPCN) to commence construction of two 615-megawatt coal-fired units (the Oak Creek expansion) to be located adjacent to the site of Wisconsin Electric's existing Oak Creek Power Plant. We anticipate that the first unit will be operational in 2009 and the second unit will be operational in 2010. The total costs for the two units were set at approximately $2.2 billion, and the order provided for the recovery of excess costs

24
of up to 5% of the total project, subject to a prudence review by the PSCW. In June 2005, construction commenced at the site. In November 2005, we completed the sale of approximately a 17% interest in the project to two unaffiliated entities, who will share ratably in the construction costs.

The CPCN granted for the construction of the Oak Creek expansion was the subject of a number of legal challenges by third parties; these legal challenges were resolved in June 2005. We have received all permits necessary to commence construction. Certain of these permits continue to be contested, but remain in effect unless and until overturned by a reviewing court or administrative law judge.

The Wisconsin Department of Natural Resources (WDNR) Chapter 30 permit for wetlands and waterways alterations and construction on the bed of Lake Michigan for the construction of the Oak Creek expansion was the subject of legal challenges. The permit was issued following a contested case proceeding and was subsequently appealed to the Circuit Court for Dane County. The circuit court dismissed the challenge on procedural grounds. In February 2006, the Wisconsin Court of Appeals affirmed the lower court's decision dismissing the case. The period for appeal of that decision to the Wisconsin Supreme Court has expired.

A contested case hearing for the Wisconsin Pollutant Discharge Elimination System permit was held in March 2006. We anticipate a decision by the administrative law judge in 2006.

UTILITY RATES AND REGULATORY MATTERS

In January 2006, the PSCW issued an order that increased our electric, gas and steam rates effective January 26, 2006. We anticipate that these base rates will remain in effect through December 2007. A discussion of this order follows.

Electric Rates:   In July 2005, Wisconsin Electric filed a limited rate proceeding whereby it requested an increase in electric revenues to recover certain specific costs which totaled approximately $143.6 million. In October 2005, Wisconsin Electric amended its original application to include fuel and purchased power costs. The January 2006 order authorized an annual increase to our electric revenues of $222.0 million. This increase covered specific costs associated with fuel and purchased power, costs associated with our continued investments in our Power the Future strategy, increased transmission costs and costs associated with additional sources of renewable energy. The January 2006 order also addressed Wisconsin Electric's recovery of fuel and purchased power costs in its electric rates. For 2006, Wisconsin Electric agreed to refund to customers any fuel revenues that it receives that are in excess of fuel costs that it incurs, a s defined by the Wisconsin fuel rules. Any refund would also include interest. For 2007, Wisconsin Electric will operate under a fuel cost adjustment clause in the Wisconsin retail jurisdiction whereby fuel revenues may be adjusted prospectively if fuel costs fall outside a plus or minus 2% band. The January 2006 order authorized a return on equity of 11.2% for Wisconsin Electric operations.

Gas Rates:   The gas operations of Wisconsin Electric and Wisconsin Gas went through a traditional rate proceeding whereby the revenues were set to recover projected costs and to provide a return on rate base. The January 2006 order provided for increases in gas revenues totaling $60.1 million which was based on an authorized return on equity of 11.2%.

Steam Rates:   The steam rate proceeding was a traditional rate proceeding. The January 2006 order provided for an increase in steam rates of $7.8 million to be phased in over a two year period beginning in 2006. The rate increase was based on an authorized return on equity of 11.2%.

25

See Factors Affecting Results, Liquidity and Capital Resources -- Utility Rates and Regulatory Matters in Item 7 of our 2005 Annual Report on Form 10-K for additional information regarding our utility rates and other regulatory matters.

Public Utility Holding Company Act of 2005 (PUHCA 2005)

Wisconsin Energy and Wisconsin Electric were exempt holding companies under the Public Utility Holding Company Act of 1935 (PUHCA 1935), and, accordingly, were exempt from that law's provisions other than with respect to certain acquisitions of securities of a public utility. However, the Energy Policy Act of 2005 repealed PUHCA 1935 and enacted PUHCA 2005, transferring jurisdiction over holding companies from the SEC to the Federal Energy Regulatory Commission(FERC). In March 2006, each of Wisconsin Energy and Wisconsin Electric filed with the FERC notification of its status as a holding company as required under the FERC regulations implementing PUCHA 2005 and request for exempt status similar to that held under PUHCA 1935. If Wisconsin Energy and Wisconsin Electric are unable to obtain exempt status from FERC, both companies may become subject to increased regulation as holding companies by the FERC.

Renewables

In March 2006, Wisconsin enacted new public benefits legislation, 2006 Wisconsin Act 141 (Act), that changes the renewable energy requirements for utilities. The Act establishes a statewide mandate for energy required from renewable sources of no less than 5% by 2010 and 10% by 2015 of total retail energy delivered. We must obtain approximately 210 megawatts of additional renewable capacity by 2010 and another approximately 610 megawatts of additional renewable capacity by 2015 to meet the retail energy delivered requirements. We have already started development of additional sources of renewable energy to comply with commitments made as part of our Power the Future initiative which will assist us in complying with the Act. See Wind Farms discussion below.

The Act allows the PSCW to delay implementation of the renewable portfolio standard if it finds that achieving the renewable requirement would be too expensive or would lessen reliability, or that new renewable projects could not be permitted on a timely basis or could not be served by adequate transmission facilities. The previous law did not include similar provisions. The Act provides that if a utility is in compliance with the renewable energy and energy efficiency requirements as determined by the PSCW, then the utility is considered in compliance with the Energy Priority Law. Prior to this Act, there had been no agreement on how to determine compliance with the Energy Priority Law.

We are evaluating the requirements of the Act. Additionally, the details of the new requirements are subject to administrative rulemaking that could take up to a year to complete.

Wind Farms

In June 2005, we purchased the development rights to two wind farm projects from Navitas Energy Inc. We plan to develop the wind sites and construct wind turbines with a combined generating capacity of between approximately 130 to 200 megawatts. We estimate that the capital cost of the project, excluding Allowance for Funds Used During Construction, will be in the range of $250 to $320 million. We filed for approval of a CPCN with the PSCW in March 2006, and we are working to secure any additional environmental permits necessary to commence construction. We expect the turbines to be placed in service between 2007 and 2008, dependent upon the availability of wind turbines and the receipt of necessary regulatory approvals.

26

NUCLEAR OPERATIONS

Wisconsin Electric owns two 518-megawatt electric generating units (Unit 1 and Unit 2) at Point Beach Nuclear Plant in Two Rivers, Wisconsin. The Plant is operated by Nuclear Management Company, LLC (NMC), a joint venture of the Company and affiliates of other unaffiliated utilities. In February 2006, we announced that we were undertaking a formal review regarding our options for the ownership and operation of Point Beach. The options that we are evaluating include: (1) continued operation by NMC, (2) continued operation by a third party operator other than NMC, (3) a return to in-house operation of the plant by Wisconsin Electric and (4) the sale of the Point Beach facility. We expect to complete this formal review in the fourth quarter of 2006.

Each Unit at the Plant has a scheduled refueling outage approximately every 18 months. During 2006, we have one scheduled refueling outage which is expected to occur during the fourth quarter. In 2005 we had two scheduled outages. In 2005, the Unit 2 outage was over the second and third quarters and the Unit 1 outage was over the third and fourth quarters. During the 2005 scheduled refueling outages we replaced the reactor vessel heads in each Unit. This work, along with other planned maintenance, resulted in longer than normal outages. During scheduled refueling outages, we incur significant operations and maintenance costs for work performed during the outages and we incur costs associated with replacement power.

See Factors Affecting Results, Liquidity and Capital Resources -- Nuclear Operations in Item 7 of our 2005 Annual Report on Form 10-K for additional information regarding our nuclear operations.

ELECTRIC TRANSMISSION

Effective April 1, 2005, Wisconsin Electric and Edison Sault began participating in the Midwest Independent Transmission System Operator, Inc.'s (MISO) bid-based energy market (MISO Midwest Market) which changed how our generating units are dispatched and how we buy and sell power.

In MISO, base transmission costs are currently being paid by load serving entities (LSE) located in the service territories of each MISO transmission owner. FERC also ordered a seams elimination charge to be paid by MISO LSE's from December 1, 2004 until March 31, 2006, to compensate transmission owners for the loss of revenues resulting from the joining of a Regional Transmission Organizationand/or FERC's elimination of through and out transmission charges between the MISO and PJM Interconnection, L.L.C. The details of the seams elimination charge and the quantification of the existing transaction charge are the subject of a hearing process initiated by FERC in a February 2005 order. In January 2006, Wisconsin Electric along with certain other parties to the proceeding, submitted an offer of settlement to the presiding administrative law judge that resolved all issues set for hearing that impact Wisconsin Electric with regard to the continued payment of th rough and out transmission charges as well as the seams elimination charge. The administrative law judge certified the settlement to the FERC, and the FERC approved the settlement on April 13, 2006. As a result, Wisconsin Electric expects to receive in the second quarter of 2006 a small refund of transmission charges in excess of the seams elimination charge. See Factors Affecting Results, Liquidity and Capital Resources -- Industry Restructuring and Competition -- Electric Transmission and Energy Markets -- in Item 7 of our 2005 Annual Report on Form 10-K for additional information regarding MISO.

OTHER MATTERS

Guardian Pipeline:   In April 2006, Wisconsin Energy sold its one-third interest in Guardian Pipeline L.L.C (Guardian) to an affiliate of Northern Border Partners, L.P. for approximately $38.5 million. The sale is expected to generate a small after-tax gain. Neither Wisconsin Electric nor Wisconsin Gas has an

27
ownership interest in Guardian. Guardian owns an interstate natural gas pipeline from the Joliet, Illinois market hub to southeastern Wisconsin that is designed to serve the growing demand for natural gas in Wisconsin and Northern Illinois. Guardian pipeline began commercial operation in early December 2002. We have committed to purchase 650,000 dekatherms (approximately 87% of the pipeline's total capacity) per day of capacity on the pipeline over a long-term contract that expires in December 2012.

PART II -- OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The following should be read in conjunction with Item 3. Legal Proceedings in Part I of our 2005 Annual Report on
Form 10-K.

In addition to those legal proceedings discussed in our reports to the SEC, we are currently, and from time to time, subject to claims and suits arising in the ordinary course of business. Although the results of these legal proceedings cannot be predicted with certainty, we believe, after consultation with legal counsel, that the ultimate resolution of these proceedings will not have a material adverse effect on our financial condition.

UTILITY RATES AND REGULATORY MATTERS

See Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations -- Factors Affecting Results, Liquidity and Capital Resources -- Utility Rates and Regulatory Matters in Part I of this report for information concerning rate matters in the jurisdictions where Wisconsin Electric, Wisconsin Gas and Edison Sault do business.

Power the Future:   See Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations -- Factors Affecting Results, Liquidity and Capital Resources -- Power the Future in Part I of this report for information concerning our Power the Future strategy.

OTHER MATTERS

Stray Voltage:   In recent years, several actions by dairy farmers have been commenced or claims made against Wisconsin Electric for loss of milk production and other damages to livestock allegedly caused by stray voltage resulting from the operation of its electrical system.

On February 26, 2004, a Wisconsin jury awarded $850,000 to a dairy farmer who alleged that Wisconsin Electric's distribution system caused damages to his livestock. Wisconsin Electric appealed this decision. In April 2006, the Wisconsin Court of Appeals affirmed the jury's verdict against Wisconsin Electric awarding $1.3 million, including interest and costs, to the plaintiffs in this suit.

In May 2005, a stray voltage lawsuit was filed against Wisconsin Electric. We do not believe the lawsuit has merit and we will vigorously defend the case. This claim against Wisconsin Electric is not expected to have a material adverse effect on our financial condition or results of operations.

Even though any claims which may be made against Wisconsin Electric with respect to stray voltage and ground currents are not expected to have a material adverse effect on its financial condition, we continue to evaluate various options and strategies to mitigate this risk.

Arbitration Proceedings:   Our largest electric customer owns two mines that operate in the Upper Peninsula of Michigan. The mines represent approximately 7% of our annual electric sales. However, the earnings are insignificant to us. The mines have special negotiated contracts that expire in December 2007. The contracts have price caps for approximately 80% of the energy sales. The mines are billed at rates reflecting incremental costs and amounts billed that exceed the price caps are refunded without interest in the year following the contract year. We do not recognize revenue on amounts billed that exceed the price caps.

31

The incremental power costs in the Upper Peninsula of Michigan are now determined by MISO. In April 2005, we began to bill the mines the incremental power costs as quantified by the MISO Midwest Market. The mines have notified us that they are disputing these billings and they have placed the disputed amounts in escrow. In September 2005, the mines notified us that they filed for formal arbitration related to the contracts. We have notified the mines that we believe that they have failed to comply with certain notification provisions related to annual production as specified within the contracts. As of March 31, 2006, the mines have placed $75.8 million in escrow. As noted above, the amounts that have been placed in escrow primarily relate to amounts that would have been refunded without interest in the year following the contract year. At this time, we are unable to predict the outcome of the formal arbitration process, but we believe that it will not have a material impact on our financial condition or results of operations.

United States Environmental Protection Agency (EPA) Information Requests:   Wisconsin Electric and Wisconsin Gas responded to an EPA request for information pursuant to Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) Section 104(e) for the Solvay Coke and Gas Site located in Milwaukee, Wisconsin. All potentially responsive records and corporate legal files have been reviewed and responsive information was provided in October 2004. A predecessor company of Wisconsin Electric owned a parcel of property that is within the property boundaries of the site. A predecessor company of Wisconsin Gas had a customer and corporate relationship with the entity that owned and operated the site, Milwaukee Solvay Coke Company. In July 2005, Wisconsin Gas received a general notice letter from the EPA identifying Wisconsin Gas as a potentially responsible party under CERCLA. We responded to the EPA in July 2005, stating that Wisconsin Gas will partici pate in negotiations regarding the site, but that Wisconsin Gas does not admit to any liability for the site. In April 2006, we received a special notice letter from the EPA identifying both Wisconsin Gas and Wisconsin Electric as potentially responsible parties and commencing a negotiation period with EPA and other parties regarding the conduct of investigation and remediation and reimbursement of the EPA's past costs. Wisconsin Electric and Wisconsin Gas have informed the EPA that they will participate in negotiations. Although neither Wisconsin Electric or Wisconsin Gas admits to any liability for the site nor has accepted any responsibility for costs of any sort related to the property, remediation cost estimates and reserves continue to be included in the estimated manufactured gas plant values reported in Note S -- Commitments and Contingencies in the Notes to Consolidated Financial Statements contained in the 2005 Annual Report on Form 10-K.

NOW, THEREFORE, in consideration of the premises and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

“Advance” means an advance by a Lender to the Borrower as part of a Borrowing and refers to a Base Rate Advance or a Eurodollar Advance.

“Affiliate” means, with respect to any Person, any other Person directly or indirectly controlling (including but not limited to all directors and officers of such Person), controlled by or under direct or indirect common control with such Person. A Person shall be deemed to control a corporation if such Person possesses, directly or indirectly, the power (i) to vote 10% or more of the securities having ordinary voting power for the election of directors of such corporation or (ii) to direct or cause direction of the management and policies of such corporation, whether through the ownership of voting securities, by contract or otherwise.

“Agent” has the meaning ascribed to such term in the preamble hereto.

“Agreement” has the meaning ascribed to such term in the preamble hereto.

“Applicable Margin” means, with respect to Base Rate Advances, 0.0% per annum and, with respect to Eurodollar Advances, the amount per annum set forth below in the column identified by the Applicable Rating Level at the time of determination. The Applicable Margin

shall increase by an amount equal to the Utilization Fee set forth below (the “Utilization Fee”) during any period (and for only such period) in which more than 50% of the Commitments are utilized. Upon the occurrence and during the continuance of any Event of Default, the Applicable Margin shall increase by 2.0% per annum, and if any Advance is a Eurodollar Advance, it will convert to a Base Rate Advance at the end of the Interest Period then in effect for such Eurodollar Advance.

Applicable Rating Level	Level 1	Level 2	Level 3	Level 4	Level 5	Level 6	Level 7
Applicable Margin	0.11%	0.15%	0.19%	0.23%	0.26%	0.35%	0.50%
Utilization Fee	0.05%	0.05%	0.05%	0.05%	0.05%	0.10%	0.10%

Any change in the Applicable Margin shall be effective on the date on which Moody’s, S&P or Fitch, as the case may be, announces any change in any rating that results in a change in the Applicable Rating Level.

“Applicable Rating Level” means, at any time, the number set forth below in the row next to the then-applicable ratings by S&P, Moody’s and Fitch, respectively, of the Borrower’s long-term senior unsecured debt.

Moody’s Rating S&P Rating Fitch Rating	Applicable Rating Level

Baa1, BBB+ and BBB+	5

If for any reason the Agent shall have determined (which determination shall be conclusive absent manifest error) that it is unable after due inquiry to ascertain the Federal Funds Rate for any reason, including the inability or failure of the Agent to obtain sufficient quotations in accordance with the terms hereof, the Base Rate shall be determined without regard to clause (ii) of the first sentence of this definition until the circumstances giving rise to such inability no longer exist. Any change in the Base Rate due to a change in JPMorgan’s base rate or the Federal Funds Rate shall be effective on the effective date of such change in the base rate or the Federal Funds Rate, as the case may be.

SECTION 2.1. The Commitments.

Subject to the terms and conditions set forth herein, each Lender severally agrees to make Advances to the Borrower in Dollars, at any time and from time to time prior to the Maturity Date, in an amount not to exceed at any time such Lender’s Commitment, the Fronting Bank agrees to issue Letters of Credit for the account of the Borrower at any time and from time to time until the fifth Business Day preceding the Maturity Date in an aggregate stated amount at any time outstanding not to exceed the LC Commitment Amount, and each Lender agrees to purchase participations in such Letters of Credit as more fully set forth in Section 2.8; provided, however, that (i) the aggregate amount of Outstanding Credits shall not exceed the aggregate Commitments and (ii) with respect to each individual Lender, such Lender’s pro rata share of Outstanding Credits shall not exceed such Lender’s Commitment Percentage of the aggregate Commitments. Subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow Advances.

(a) Upon receipt of a Notice of Borrowing, the Agent shall promptly inform the Lenders as to the terms thereof.

(b) No Lender shall be responsible for the failure or delay by any other Lender in its obligation to make Advances hereunder; provided, however, that the failure of any Lender to

16

fulfill its obligations hereunder shall not relieve any other Lender of its obligations hereunder. Unless the Agent shall have been notified by any Lender prior to the date of any such Borrowing (in the case of a Eurodollar Borrowing) or the time of any such Borrowing (in the case of a Base Rate Borrowing) that such Lender does not intend to make available to the Agent its portion of the Borrowing to be made on such date, the Agent may assume that such Lender has made such amount available to the Agent on the date of such Borrowing, and the Agent in reliance upon such assumption, may (in its sole discretion but without any obligation to do so) make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the Agent, the Agent shall be able to recover such corresponding amount from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Agent’s demand therefor, the Agent will promptly notify the Borrower, and the Borrower shall immediately pay such corresponding amount to the Agent. The Agent shall also be entitled to recover from the Lender or the Borrower, as the case may be, interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the Agent to the Borrower to the date such corresponding amount is recovered by the Agent at a per annum rate equal to, (i) if from the Borrower, the applicable rate for such Advance pursuant to the Notice of Borrowing and (ii) if from a Lender, the Federal Funds Rate.

The Borrower shall have the option, on any Business Day, to continue existing Eurodollar Advances for a subsequent Interest Period, to convert Base Rate Advances into Eurodollar Advances or to convert Eurodollar Advances into Base Rate Advances; provided, however, that (i) each such continuation or conversion must be requested by the Borrower pursuant to a written Notice of Continuation/Conversion, in the form of Exhibit B, in compliance with the terms set forth below, (ii) except as provided in Section 4.1, Eurodollar Advances may be continued or converted into Base Rate Advances only on the last day of the Interest Period applicable hereto, (iii) Eurodollar Advances may not be continued nor may Base Rate Advances be converted into Eurodollar Advances during the existence and continuation of a Default or Event of Default and (iv) any request to extend a Eurodollar Advance that fails to comply with the terms hereof or any failure to request an extension of a Eurodollar Advance that fails to comply with the terms hereof or any failure to request an extension of a Eurodollar Advance at the end of an Interest Period shall constitute a conversion to a Base Rate Advance on the last day of the applicable Interest Period. Each continuation or conversion must be requested by the Borrower no later than 11:00 a.m. (A) on the date for a requested conversion of a Eurodollar Advance to a Base Rate Advance or (B) three Business Days prior to the date for a requested continuation of a Eurodollar Advance or conversion of a Base Rate Advance to a Eurodollar Advance, in each case pursuant to a written Notice of Continuation/Conversion submitted to the Agent, which shall set forth (1) whether the Borrower wishes to continue or convert such Advances and (2) if the request is to continue a Eurodollar Advance or convert a Base Rate Advance to a Eurodollar Advance, the Interest Period applicable thereto.

17

Borrowing consisting of Base Rate Advances shall be in a minimum amount of the lesser of $500,000 (and in integral multiples of $500,000 in excess thereof) and the remaining amount available to be borrowed; and (iii) no more than ten Eurodollar Borrowings shall be outstanding hereunder at any one time. For the purposes of this Section, all Eurodollar Borrowings with the same Interest Periods that begin and end on the same date shall be considered as one Eurodollar Borrowing, but Eurodollar Borrowings with different Interest Periods, even if they begin on the same date, shall be considered separate Eurodollar Borrowings.

SECTION 2.6. Reduction of the Commitments.

Upon at least five Business Days’ notice, the Borrower shall have the right to permanently terminate or reduce the aggregate unused amount of the Commitments at any time or from time to time; provided that each partial reduction shall be in an aggregate amount at least equal to $5,000,000 and in integral multiples of $1,000,000 above such amount and no reduction shall be made that would reduce the Commitments to an amount less than the then Outstanding Credits. Any reduction in (or termination of) the Commitments shall be permanent and may not be reinstated.

SECTION 2.7. Extension of Maturity Date.

(a) Not earlier than 45 days prior to, nor later than 30 days prior to, the then-effective Maturity Date, the Borrower may request by Requisite Notice (as defined below) made to the Agent (which shall promptly notify the Lenders) a one-year extension of the Maturity Date.

Any Lender not responding within the above time period shall be deemed not to have consented to extending the Maturity Date. The Agent shall, after receiving the notifications from all of the Lenders or the expiration of such period, whichever is earlier, notify the Borrower and the Lenders of the results thereof. The Borrower may request no more than two extensions pursuant to this Section.

(b) If any Lender declines, or is deemed to have declined, to consent to such request for extension (a “Declining Lender”), provided that (i) no Default or Event of Default has occurred and is continuing at such time and (ii) the Required Lenders are non-Declining Lenders, the Borrower may, at its own expense (such expense to include any transfer fee payable to the Agent under Section 11.3(b) and any expense pursuant to Section 4.3) and in its sole discretion, require such Declining Lender to transfer and assign in whole (but not in part) without recourse (in accordance with and subject to the terms and conditions of Section 11.3(b)) all of its interests, rights and obligations under this Agreement to an Eligible Assignee, which shall assume such assigned obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (A) such assignment shall not conflict with any law, rule or regulation or order of any court or other Governmental Authority and (B) the assigning Declining Lender

18

shall have received in immediately available funds the principal of and interest accrued to the date of such payment on the portion of the Advances hereunder held by such assigning Declining Lender and all other amounts owed to such assigning Declining Lender hereunder, including amounts owed pursuant to Sections 4.1 through 4.4.

(c) If the conditions set forth in subsection (b) above have been satisfied, the Maturity Date shall be extended (solely with respect to the non-Declining Lenders) to the date that is one year after the then-effective Maturity Date, effective as of the date to be determined by the Agent and the Borrower (the “Maturity Extension Decision Date”), and the Agent shall promptly notify the Lenders thereof. On or prior to the Maturity Extension Decision Date, the Borrower shall deliver to the Agent, in form and substance satisfactory to the Agent and the Lenders (i) the resolutions of the Board of Directors of the Borrower authorizing such extension, certified as in effect as of the Maturity Extension Decision Date and the related incumbency certificate of the Borrower, (ii) new or amended promissory notes, if requested by any new or affected Lender, evidencing the new or revised Commitment of such Lender, (iii) a certificate of the Borrower stating that on and as of such Maturity Extension Decision Date, and after giving effect to the extension to be effective on such date, (A) the representations and warranties set forth in Article VI are true and correct and (B) no Default or Event of Default is continuing. The Agent shall distribute an amended Schedule I to this Agreement (which shall thereafter be incorporated into this Agreement), to reflect any changes in Lenders, the Commitments and each Lender’s Commitment Percentage.

(d) For purposes of this Section:

(i) “Responsible Officer” means the chairman of the board, chief executive officer, president, chief financial officer, treasurer, or assistant treasurer of the Borrower. Any document or certificate hereunder that is signed by a Responsible Officer shall be conclusively presumed to have been authorized by all necessary corporate action on the part of the Borrower and such Responsible Officer shall be conclusively presumed to have acted on behalf of the Borrower.

(ii) “Requisite Notice” means irrevocable written notice to the intended recipient or irrevocable telephonic notice to the intended recipient, immediately followed by a written notice to such recipient. Such notices shall be (i) delivered to such recipient at the address or telephone number specified on Schedule II or as otherwise designated by such recipient by Requisite Notice to each other party hereto, and (ii) if made by the Borrower, given or made by a Responsible Officer. Any written notice delivered shall be delivered as provided in Section 11.1. Any notice sent by other than hardcopy shall be promptly confirmed by a telephone call to the recipient and, if requested by the Agent, by a manually-signed hardcopy thereof.

SECTION 2.8. Letters of Credit.

(a) Subject to the terms and conditions hereof, the Fronting Bank agrees to issue Letters of Credit from time to time for the account of the Borrower (or to extend the stated maturity thereof or to modify or amend the terms thereof) for the purposes set forth in Section 7.9 on not less than five Business Days’ prior notice thereof by delivery of a Request for

19

Issuance to the Agent (which shall promptly distribute copies thereof to the Lenders) and the Fronting Bank. Each Request for Issuance shall specify (i) the date (which shall be a Business Day) of issuance of such Letter of Credit (or the date of effectiveness of such extension, modification or amendment) and the stated expiry date thereof (which shall be no later than one year following the date of such issuance), (ii) the proposed stated amount of such Letter of Credit, (iii) the name and address of the beneficiary of such Letter of Credit and (iv) a statement of drawing conditions applicable to such Letter of Credit, and if such Request for Issuance relates to an amendment or modification of a Letter of Credit, it shall be accompanied by the consent of the beneficiary of the Letter of Credit thereto. Each Request for Issuance shall be irrevocable unless modified or rescinded by the Borrower not less than two Business Days prior to the proposed date of issuance (or effectiveness) specified therein. Not later than 12:00 noon (New York City time) on the proposed date of issuance (or effectiveness) specified in such Request for Issuance, and upon fulfillment of the applicable conditions precedent and the other requirements set forth herein, the Fronting Bank shall issue (or extend, amend or modify) such Letter of Credit and provide notice and a copy thereof to the Agent, which shall promptly furnish copies thereof to the Lenders. The Fronting Bank shall provide to the Agent, on a monthly basis, a list of the amounts and expiration dates of all undrawn Letters of Credit, a copy of which list the Agent shall furnish to each Lender that requests such list.

(b) No Letter of Credit shall be requested or issued hereunder if, after the issuance thereof, (i) the Outstanding Credits would exceed the aggregate Commitments or (ii) the LC Outstandings would exceed the LC Commitment Amount.

(c) In the event that any Letter of Credit remains outstanding beyond the fifteenth day prior to the Maturity Date, the Borrower shall either (i) pay to the Agent an amount equal to 103% of the LC Outstandings on the later of such date and the date of issuance of such Letter of Credit, which amount the Agent shall hold in the Cash Collateral Account for the account of the Borrower, without interest, for the purpose of paying any draft presented, with the excess, if any, to be returned to the Borrower upon termination or expiration of such Letter of Credit and payment in full of all amounts due hereunder or (ii) deliver a back-up letter of credit to the Agent securing the Borrower’s reimbursement obligations with respect to such Letter of Credit in form and substance acceptable to the Fronting Bank and the Agent and from a creditworthy financial institution acceptable to the Agent. While any Letter of Credit is outstanding, the Agent may not release funds held in the Cash Collateral Account pursuant to this subsection (c) without the consent of all Lenders.

(d) Each Lender, upon issuance of a Letter of Credit, shall be deemed to have purchased without recourse a participation from the Fronting Bank in such Letter of Credit and the rights and obligations arising thereunder and any collateral relating thereto, in each case in an amount equal to such Lender’s Commitment Percentage of the obligations under such Letter of Credit, and shall absolutely, unconditionally and irrevocably assume, as primary obligor and not as surety, and be obligated to pay to the Fronting Bank therefor and discharge when due, such Lender’s Commitment Percentage of the obligations arising under such Letter of Credit. Without limiting the scope and nature of each Lender’s participation in any Letter of Credit, to the extent that the Fronting Bank has not been reimbursed as required hereunder or under any such Letter of Credit, each Lender shall pay to the Fronting Bank its Commitment Percentage of such unreimbursed drawing in same day funds on the day of notification by the Fronting Bank of an

20

unreimbursed drawing pursuant to the provisions of subsection (e). The obligation of each Lender so to reimburse the Fronting Bank shall be absolute and unconditional and shall not be affected by the occurrence of a Default, an Event of Default or any other occurrence or event. Any such reimbursement shall not relieve or otherwise impair the obligation of the Borrower to reimburse the Fronting Bank under any Letter of Credit, together with interest as hereinafter provided.

(e) In the event of any drawing under any Letter of Credit, the Fronting Bank will promptly notify the Borrower. Unless the Borrower shall immediately notify the Fronting Bank of its intent otherwise to reimburse the Fronting Bank for any drawing made prior to the Maturity Date, the Borrower shall be deemed to have requested a Base Rate Advance in the amount of such drawing as provided in subsection (f), the proceeds of which will be used to satisfy the reimbursement obligation of the Borrower with respect to such drawing. If, at any time on or after the Maturity Date, any drawing is made under any Letter of Credit, the Fronting Bank shall instruct the Agent to withdraw from the Cash Collateral Account funds in an amount equal to the amount of such drawing, which the Agent shall transfer to the Fronting Bank in order to reimburse the Fronting Bank for such drawing. In the case of any drawing made under any Letter of Credit prior to the Maturity Date, the Borrower shall reimburse the Fronting Bank on the day such drawing is paid either with the proceeds of an Advance obtained hereunder or otherwise in same day funds as provided herein. If the Borrower shall fail to reimburse the Fronting Bank as provided herein, the unreimbursed amount of such drawing shall bear interest at a per annum rate equal to the Base Rate plus two percent (2%) per annum. The Borrower’s reimbursement obligations hereunder shall be absolute and unconditional under all circumstances irrespective of any rights of set-off, counterclaim or defense to payment that the applicable account party or the Borrower may claim or have against the Fronting Bank, the Lenders, the beneficiary of the Letter of Credit drawn upon or any other Person, including, without limitation, any defense based on any failure of the applicable account party or the Borrower to receive consideration or the legality, validity, regularity or unenforceability of the Letter of Credit. The Fronting Bank will promptly notify the Lenders of the amount of any unreimbursed drawing and each Lender shall promptly pay to the Fronting Bank, in immediately available funds, the amount of such Lender’s Commitment Percentage of such unreimbursed drawing. Such payment shall be made on the day such notice is received by such Lender from the Fronting Bank if such notice is received at or before 2:00 p.m., otherwise such payment shall be made at or before 12:00 noon on the Business Day next succeeding the day such notice is received. If such Lender does not pay such amount to the Fronting Bank in full upon such request, such Lender shall, on demand, pay to the Fronting Bank interest on the unpaid amount during the period from the date the Lender received the notice regarding the unreimbursed drawing until the Lender pays such amount to the Fronting Bank in full at a rate per annum equal to, if paid within two Business Days of the date of drawing, the Federal Funds Rate and thereafter at a rate equal to the Base Rate. Each Lender’s obligation to make such payment to the Fronting Bank, and the right of the Fronting Bank to receive the same, shall be absolute and unconditional, shall not be affected by any circumstance whatsoever and without regard to the termination of this Agreement or the Commitments, the existence of a Default or Event of Default or the acceleration of the obligations hereunder and shall be made without any offset, abatement, withholding or reduction whatsoever. Simultaneously with the making of each such payment by a Lender to the Fronting Bank, such Lender shall, automatically and without any further action on the part of the Fronting Bank or such Lender, acquire a participation in an amount equal to such payment (excluding the

21

portion of such payment constituting interest owing to the Fronting Bank) in the related unreimbursed drawing portion of the LC Outstandings and in the interest thereon, and shall have a claim against the Borrower with respect thereto.

(f) On any day on which the Borrower shall have requested, or been deemed to have requested, a Borrowing to reimburse a drawing under a Letter of Credit, the Fronting Bank shall give notice to the Lenders that a Borrowing has been requested or deemed requested in connection with a drawing under a Letter of Credit, in which case an Advance comprised solely of Base Rate Advances (each such borrowing, a “Mandatory Borrowing”) shall be immediately made by all Lenders (without giving effect to any termination of the Commitments pursuant to Section 9.1) pro rata based on each Lender’s Commitment Percentage, and the proceeds thereof shall be paid directly to the Fronting Bank for application to the applicable LC Outstandings. Each Lender hereby irrevocably agrees to make such Base Rate Advances upon any such request or deemed request on account of each such Mandatory Borrowing in the amount and in the manner specified in the preceding sentence and on the same such date notwithstanding (i) the amount of Mandatory Borrowing may not comply with the minimum amount for Borrowings otherwise required hereunder, (ii) whether any conditions specified in Article III are then satisfied, (iii) whether a Default or Event of Default then exists, (iv) failure of any such request or deemed request for a Borrowing to be made by the time otherwise required hereunder, (v) the date of such Mandatory Borrowing, or (vi) any reduction in or any termination of the Commitments. Such funding of Borrowings shall be made on the day notice of such Mandatory Borrowing is received by each Lender from the Fronting Bank if such notice is received at or before 2:00 p.m., otherwise such payment shall be made at or before 12:00 noon on the Business Day next succeeding the day such notice is received. In the event that any Mandatory Borrowing cannot for any reason be made on the date otherwise required above (including, without limitation, as a result of the commencement of a proceeding under any applicable bankruptcy law with respect to the Borrower), then each Lender hereby agrees that it shall forthwith fund (as of the date the Mandatory Borrowing would otherwise have occurred, but adjusted for any payments received from the Borrower on or after such date and prior to such purchase) its Commitment Percentage of the outstanding LC Outstandings; provided, further, that in the event any Lender shall fail to fund its Commitment Percentage on the day the Mandatory Borrowing would otherwise have occurred, then the amount of such Lender’s unfunded Commitment Percentage therein shall bear interest payable to the Fronting Bank upon demand, if paid within two Business Days of such date, at the Federal Funds Rate, and thereafter, at the Base Rate.

(g) The payment obligations of each Lender under subsection (d) and of the Borrower under this Agreement in respect of any payment under any Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances:

(i) any lack of validity or enforceability of any Credit Document or any other agreement or instrument relating thereto or to such Letter of Credit;

(ii) any amendment or waiver of, or any consent to departure from, the terms of any Credit Document or such Letter of Credit;

22

(iii) the existence of any claim, set-off, defense or other right that the Borrower may have at any time against any beneficiary, or any transferee, of such Letter of Credit (or any persons for whom any such beneficiary or any such transferee may be acting), the Fronting Bank, or any other person, whether in connection with any Credit Document, the transactions contemplated hereby or by such Letter of Credit, or any unrelated transaction;

(iv) any statement or any other document presented under such 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 in good faith by the Fronting Bank under the Letter of Credit issued by the Fronting Bank against presentation of a draft or certificate that does not comply with the terms of such Letter of Credit; or

(vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

(h) The Borrower assumes all risks of the acts and omissions of any beneficiary or transferee of any Letter of Credit. Neither the Fronting Bank, the Lenders nor any of their respective officers, directors, employees, agents or Affiliates shall be liable or responsible for (i) the use that may be made of such Letter of Credit or any acts or omissions of any beneficiary or transferee thereof in connection therewith, (ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged, (iii) payment by the Fronting Bank against presentation of documents that do not comply with the terms of such Letter of Credit, including failure of any documents to bear any reference or adequate reference to such Letter of Credit, or (iv) any other circumstances whatsoever in making or failing to make payment under such Letter of Credit, except that, and notwithstanding subsection (f) and the foregoing clauses (i) through (iii), the Borrower and each Lender shall have the right to bring suit against the Fronting Bank, and the Fronting Bank shall be liable to the Borrower and any Lender, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower or such Lender that the Borrower or such Lender proves were caused by the Fronting Bank’s willful misconduct or gross negligence, including, in the case of the Borrower, the Fronting Bank’s willful failure to make timely payment under such Letter of Credit following the presentation to it by the beneficiary thereof of a draft and accompanying certificate(s) that strictly comply with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, the Fronting Bank may accept sight drafts and accompanying certificates presented under the Letter of Credit issued by the Fronting Bank that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and payment against such documents shall not constitute willful misconduct or gross negligence by the Fronting Bank. Notwithstanding the foregoing, no Lender shall be obligated to indemnify the Borrower for damages caused by the Fronting Bank’s willful misconduct or gross negligence.

(i) The letters of credit listed on Schedule III shall be deemed “Letters of Credit” upon the occurrence of the Effective Date.

(ii) All Eurodollar Advances shall accrue interest at the Eurodollar Rate applicable to such Eurodollar Advance.

(b) Interest Payments. Interest on Advances shall be due and payable in arrears on each Interest Payment Date.

SECTION 3.2. Prepayments.

(a) Optional Prepayments. The Borrower shall have the right to prepay Advances in whole or in part from time to time without premium or penalty; provided, however, that (i) Eurodollar Advances may be prepaid only on two Business Days’ prior written notice to the Agent, and any prepayment of Eurodollar Advances will be subject to Section 4.3, and (ii) each partial prepayment of Advances shall be in the minimum principal amount of $1,000,000 and in increments of $1,000,000 in excess thereof; provided that if less than $1,000,000 would remain outstanding after such prepayment, such prepayment shall be in the amount of the entire outstanding principal amount of the Advances. Amounts prepaid hereunder shall be applied as the Borrower may elect; provided that if the Borrower fails to specify an optional prepayment then such prepayment shall be applied first to Base Rate Advances, and then to Eurodollar Advances in direct order of Interest Period maturities.

(b) Mandatory Prepayments. If at any time the Outstanding Credits exceed the aggregate Commitments, the Borrower shall immediately make a principal payment to the Agent and/or deposit funds in the Cash Collateral Account in respect of LC Outstandings pursuant to Section 9.2(d) for the ratable accounts of the Lenders as shall be necessary in order that the Outstanding Credits (after giving effect to such prepayment) minus the amount held in the Cash Collateral Account after giving effect to such cash collateralization will be less than or equal to the aggregate Commitments. Any payments made under this subsection (b) shall be subject to Section 4.3 and, in the case of principal payments, shall be applied first to Base Rate Advances, and then to Eurodollar Advances in direct order of Interest Period maturities.

SECTION 3.3. Payment in full at Maturity.

On the Maturity Date, the entire outstanding principal balance of all Advances, together with accrued but unpaid interest and all other sums owing under this Agreement, shall be due and payable in full.

24

SECTION 3.4. Fees.

(a) Facility Fee. In consideration of the Commitments being made available by the Lenders hereunder, the Borrower agrees to pay to the Agent, for the pro rata benefit of each Lender, a facility fee at a rate per annum equal to the Facility Fee Percentage in effect from time to time commencing on the date hereof, on the Commitment from time to time of such Lender (regardless of usage), quarterly in arrears, on the last day of each March, June, September and December, on the Maturity Date, and (if applicable) on the date after the Maturity Date on which all Advances and other amounts payable by the Borrower hereunder are paid in full (without regard to any termination of the Commitments on the Maturity Date).

(b) LC Fee. The Borrower agrees to pay the Agent for the account of the Fronting Bank an issuance fee (an “Issuance Fee”) and such other charges as are separately agreed upon with the Fronting Bank, and agrees to pay to the Agent for the account of the Lenders a fee (the “LC Fee”) on the face amount of each Letter of Credit issued by the Fronting Bank calculated at a rate per annum at all times equal to the Applicable Margin in effect for Eurodollar Rate Advances, in each case computed on the basis of the actual number of days that each Letter of Credit is outstanding over a year of 360 days, payable quarterly in arrears on each March 31, June 30, September 30 and December 31, and on the date that such Letter of Credit expires or is drawn in full.

(c) Administrative Fees. The Borrower agrees to pay such other fees as agreed to by the Borrower in the Fee Letters.

SECTION 3.5. Place and Manner of Payments.

All payments of principal, interest, fees, expenses and other amounts to be made by the Borrower under this Agreement shall be received without setoff, deduction or counterclaim not later than 2:00 p.m. on the date when due in Dollars and in immediately available funds by the Agent at its offices in New York, New York. The Borrower shall, at the time it makes any payment under this Agreement, specify to the Agent the Outstanding Credits, fees or other amounts payable by the Borrower hereunder to which such payment is to be applied (and in the event that it fails to specify, or if such application would be inconsistent with the terms hereof, the Agent shall distribute such payment to the Lenders in such manner as it reasonably determines in its sole discretion).

SECTION 3.6. Pro Rata Treatment.

Except to the extent otherwise provided herein, all Borrowings, each payment or prepayment of principal of any Advance, each payment of interest on the Advances, each payment of facility fees, LC Fees, each reduction of the Commitments, and each conversion or continuation of any Advance, shall be allocated pro rata among the Lenders in accordance with the respective Commitment Percentages; provided that, if any Lender shall have failed to fund its applicable pro rata share of any Borrowing, then any amount to which such Lender would otherwise be entitled pursuant to this Section 3.6 shall instead be payable to the Agent until the share of such Borrowing not funded by such Lender has been repaid; and provided, further, that in the event any amount paid to any Lender pursuant to this Section 3.6 is rescinded or must

25

otherwise be returned by the Agent, each Lender shall, upon the request of the Agent, repay to the Agent the amount so paid to such Lender, with interest for the period commencing on the date such payment is returned by the Agent until the date the Agent receives such repayment at a rate per annum equal to, during the period to but excluding the date two Business Days after such request, the Federal Funds Rate, and thereafter, the Base Rate plus two percent per annum.

SECTION 3.7. Computations of Interest and Fees.

(a) Except for Base Rate Advances bearing interest determined under clause (i) of the definition of Base Rate, on which interest shall be computed on the basis of a 365 or 366 day year, as the case may be, all computations of interest and fees hereunder shall be made on the basis of the actual number of days elapsed over a year of 360 days.

(b) It is the intent of the Lenders and the Borrower to conform to and contract in strict compliance with applicable usury law from time to time in effect. All agreements between the Lenders and the Borrower are hereby limited by the provisions of this subsection, which shall override and control all such agreements, whether now existing or hereafter arising and whether written or oral. In no way, nor in any event or contingency (including but not limited to prepayment or acceleration of the maturity of any obligation), shall the interest taken, reserved, contracted for, charged, or received under this Agreement or otherwise exceed the maximum nonusurious amount permissible under applicable law. If, from any possible construction of any of the Credit Documents or any other document, interest would otherwise be payable in excess of the maximum nonusurious amount, any such construction shall be subject to the provisions of this subsection and such documents shall be automatically reduced to the maximum nonusurious amount permitted under applicable law, without the necessity of execution of any amendment or new document. If any Lender shall ever receive anything of value that is characterized as interest on the Advances under applicable law and that would, apart from this provision, be in excess of the maximum lawful amount, an amount equal to the amount that would have been excessive interest shall, without penalty, be applied to the reduction of the principal amount owing on the Advances and not to the payment of interest, or refunded to the Borrower or the other payor thereof if and to the extent such amount that would have been excessive exceeds such unpaid principal amount of the Advances. The right to demand payment of the Advances or any other indebtedness evidenced by any of the Credit Documents does not include the right to receive any interest that has not otherwise accrued on the date of such demand, and the Lenders do not intend to charge or receive any unearned interest in the event of such demand. All interest paid or agreed to be paid to the Lenders with respect to the Advances shall, to the extent permitted by applicable law, be amortized, prorated, allocated, and spread throughout the full stated term (including any renewal or extension) of the Advances so that the amount of interest on account of such indebtedness does not exceed the maximum nonusurious amount permitted by applicable law.

SECTION 3.8. Sharing of Payments.

Each Lender agrees that, in the event that any Lender shall obtain payment in respect of any Extension of Credit or any other obligation owing to such Lender under this Agreement through the exercise of a right of set-off, banker’s lien, counterclaim or otherwise (including, but not limited to, pursuant to the Bankruptcy Code) in excess of its pro rata share as provided for in

26

this Agreement, such Lender shall promptly purchase from the other Lenders a participation in such Extension of Credit and other obligations, in such amounts and with such other adjustments from time to time, as shall be equitable in order that all Lenders share such payment in accordance with their respective ratable shares as provided for in this Agreement. Each Lender further agrees that if a payment to a Lender (which is obtained by such Lender through the exercise of a right of set-off, banker’s lien, counterclaim or otherwise) shall be rescinded or must otherwise be restored, each Lender that shall have shared the benefit of such payment shall, by repurchase of a participation theretofore sold, return its share of that benefit to each Lender whose payment shall have been rescinded or otherwise restored. The Borrower agrees that any Lender so purchasing such a participation may, to the fullest extent permitted by law, exercise all rights of payment, including set-off, banker’s lien or counterclaim, with respect to such participation as fully as if such Lender were a holder of such Advance or other obligation in the amount of such participation. Except as otherwise expressly provided in this Agreement, if any Lender shall fail to remit to the Agent or any other Lender an amount payable by such Lender to the Agent or such other Lender pursuant to this Agreement on the date when such amount is due, such payments shall accrue interest thereon, for each day from the date such amount is due until the day such amount is paid to the Agent or such other Lender, at a rate per annum equal to the Federal Funds Rate. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a setoff to which this Section 3.8 applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders under this Section 3.8 to share in the benefits of any recovery on such secured claim.

SECTION 3.9. Additional Interest on Advances.

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

SECTION 3.10. Evidence of Debt.

(a) Each Lender shall maintain an account or accounts evidencing each Advance made by such Lender to the Borrower from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement. Each Lender will make reasonable efforts to maintain the accuracy of its account or accounts and to promptly update its account or accounts from time to time, as necessary.

27

(b) The Agent shall maintain the Register pursuant to Section 11.3(c), and a subaccount for each Lender, in which Register and subaccounts (taken together) shall be recorded (i) the amount, type and Interest Period of each such Advance hereunder, (ii) the amount of any principal or interest due and payable or to become due and payable to each Lender hereunder and (iii) the amount of any sum received by the Agent hereunder from or for the account of the Borrower and each Lender’s share thereof. The Agent will make reasonable efforts to maintain the accuracy of the subaccounts referred to in the preceding sentence and to promptly update such subaccounts from time to time, as necessary.

(c) The entries made in the accounts, Register and subaccounts maintained pursuant to subsection (b) (and, if consistent with the entries of the Agent, subsection (a)) shall be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, however, that the failure of any Lender or the Agent to maintain any such account, such Register or such subaccount, as applicable, or any error therein, shall not in any manner affect the obligation of the Borrower to repay the Advances made by such Lender in accordance with the terms hereof.

(d) Any Lender may request that its Advances be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note, in a form acceptable to the Agent, payable to the order of such Lender. Thereafter, the Advances evidenced by such promissory note and interest thereon shall at all times (including after any assignment pursuant to Section 11.3) be represented by one or more promissory notes payable to the order of the payee named therein or any assignee pursuant to Section 11.3, except to the extent that any such Lender or assignee subsequently returns any such promissory note for cancellation and requests that such Advances once again be evidenced as described in subsections (a) and (b) above.

ARTICLE IV

ADDITIONAL PROVISIONS REGARDING ADVANCES

SECTION 4.1. Eurodollar Borrowing Provisions.

(a) Unavailability. In the event that the Agent shall have determined in good faith (i) that Dollar deposits in the principal amounts requested with respect to a Eurodollar Borrowing are not generally available in the London interbank Eurodollar market or (ii) that reasonable means do not exist for ascertaining the Eurodollar Rate, the Agent shall, as soon as practicable thereafter, give notice of such determination to the Borrower and the Lenders. In the event of any such determination under clause (i) or (ii) above, until the Agent shall have advised the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (A) any request by the Borrower for Eurodollar Borrowings shall be deemed to be a request for Base Rate Borrowings, (B) any request by the Borrower for conversion into or continuation of Eurodollar Borrowings shall be deemed to be a request for conversion into or continuation of Base Rate Borrowings and (C) any Borrowings that were to be converted or continued as Eurodollar Borrowings on the first day of an Interest Period shall be converted to or continued as Base Rate Borrowings.

28

(b) Change in Legality. Notwithstanding any other provision herein, if any change, after the date hereof, in any law or regulation (including the introduction of any new law or regulation) or in the interpretation thereof by any Governmental Authority charged with the administration or interpretation thereof shall make it unlawful for any Lender to make or maintain any Eurodollar Advance or to give effect to its obligations as contemplated hereby with respect to any Eurodollar Advance, then, by written notice to the Borrower and to the Agent, such Lender may:

(i) declare that Eurodollar Advances, and conversions to or continuations of Eurodollar Advances, will not thereafter be made by such Lender hereunder, whereupon any request by the Borrower for, or for conversion into or continuation of, Eurodollar Borrowings shall, as to such Lender only, be deemed a request for, or for conversion into or continuation of, Base Rate Borrowings, unless such declaration shall be subsequently withdrawn; and

(ii) require that all outstanding Eurodollar Advances made by it be converted to Base Rate Advances in which event all such Eurodollar Advances shall be automatically converted to Base Rate Advances.

In the event any Lender shall exercise its rights under clause (i) or (ii) above, all payments and prepayments of principal that would otherwise have been applied to repay the Eurodollar Advances that would have been made by such Lender or the converted Eurodollar Advances of such Lender shall instead be applied to repay the Base Rate Advances made by such Lenders in lieu of, or resulting from the conversion of, such Eurodollar Advances.

(c) Requirements of Law. If at any time a Lender shall incur increased costs or reductions in the amounts received or receivable hereunder with respect to the making, the commitment to make or the maintaining of any Eurodollar Advance because of (i) any change, after the date hereof, in any applicable law, governmental rule, regulation, guideline or order (or in the interpretation or administration thereof and including the introduction of any new law or governmental rule, regulation, guideline or such order) including, without limitation, the imposition, modification or deemed applicability of any reserves, deposits or similar requirements (such as, for example, but not limited to, a change in official reserve requirements, but, in all events, excluding reserves required under Regulation D to the extent included in the computation of additional interest under Section 3.9) or (ii) other circumstances affecting the London interbank Eurodollar market, then the Borrower shall pay to such Lender promptly upon written demand therefor, such additional amounts (in the form of an increased rate of, or a different method of calculating, interest or otherwise as such Lender may determine in its sole discretion) as may be required to compensate such Lender for such increased costs or reductions in amounts receivable hereunder.

Each determination and calculation made by a Lender under this Section 4.1 shall, absent manifest error, be binding and conclusive on the parties hereto. Any conversions of Eurodollar Advances made pursuant to this Section 4.1 shall subject the Borrower to the payments required by Section 4.3. This Section shall survive termination of this Agreement and the other Credit Documents and payment of the Advances and all other amounts payable hereunder.

29

SECTION 4.2. Capital Adequacy.

If any Lender has determined that the adoption or effectiveness, after the date hereof, of any applicable law, rule or regulation regarding capital adequacy, or any change therein (after the date hereof), 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 such Lender (or its parent corporation) 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, has or would have the effect of reducing the rate of return on such Lender’s (or parent corporation’s) capital or assets as a consequence of its commitments or obligations hereunder to a level below that which such Lender (or its parent corporation) could have achieved but for such adoption, effectiveness, change or compliance (taking into consideration such Lender’s (or parent corporation’s) policies with respect to capital adequacy), then, upon notice from such Lender, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction. Each determination by any such Lender of amounts owing under this Section 4.2 shall, absent manifest error, be conclusive and binding on the parties hereto. This Section shall survive termination of this Agreement and the other Credit Documents and payment of the Advances and all other amounts payable hereunder.

SECTION 4.3. Compensation.

The Borrower promises to indemnify each Lender and to hold each Lender harmless from any loss or expense that such Lender may sustain or incur as a consequence of (i) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Advances after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (ii) default by the Borrower in making any prepayment of a Eurodollar Advance after the Borrower has given a notice thereof in accordance with the provisions of this Agreement, (iii) the making of a prepayment of Eurodollar Advances on a day that is not the last day of an Interest Period with respect thereto and (iv) the payment, continuation or conversion of a Eurodollar Advance on a day that is not the last day of the Interest Period applicable thereto or the failure to repay a Eurodollar Advance when required by the terms of this Agreement. Such indemnification may include such additional amount or amounts as will compensate such Lender for such loss or expense actually sustained or incurred by such Lender. The agreements in this Section shall survive the termination of this Agreement and the payment of the Advances and all other amounts payable hereunder.

SECTION 4.4. Taxes.

(a) Except as provided below in this Section 4.4, all payments made by the Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any court or governmental body, agency or other official, excluding taxes measured by or imposed upon the net income of any Lender or its applicable lending office, or any branch or affiliate thereof, and all franchise taxes, branch taxes, taxes on doing business or taxes on the capital or net worth of any Lender or its applicable lending office, or any branch or

30

affiliate thereof, in each case imposed in lieu of net income taxes (i) by the jurisdiction under the laws of which such Lender, applicable lending office, branch or affiliate is organized or is located, or in which its principal executive office is located, or any nation within which such jurisdiction is located or any political subdivision thereof or (ii) by reason of any connection between the jurisdiction imposing such tax and such Lender, applicable lending office, branch or affiliate other than a connection arising solely from such Lender having executed, delivered or performed its obligations, or received payment under or enforced, this Agreement. If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) are required to be withheld from any amounts payable to an Agent or any Lender hereunder, (A) the amounts so payable to the Agent or such Lender shall be increased to the extent necessary to yield to the Agent or such Lender (after payment of all Non-Excluded Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement and any promissory notes, provided, however, that the Borrower shall be entitled to deduct and withhold any Non-Excluded Taxes and shall not be required to increase any such amounts payable to any Lender that is not organized under the laws of the United States of America or a state thereof if such Lender fails to comply with the requirements of subsection (b) whenever any Non-Excluded Taxes are payable by the Borrower, and (B) as promptly as possible after requested, the Borrower shall send to the Agent for its own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded Taxes when due to the appropriate taxing authority or fails to remit to the Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Agent and any Lender for any incremental Non-Excluded Taxes, interest or penalties that may become payable by the Agent or any Lender as a result of any such failure. The agreements in this Section shall survive the termination of this Agreement and the payment of the Borrowings and all other amounts payable hereunder.

(b) Each Lender that is not incorporated under the laws of the United States of America or a state thereof shall:

(i) (A) on or before the date of any payment by the Borrower under this Agreement to such Lender, deliver to the Borrower and the Agent (x) two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI, or successor applicable form, as the case may be, certifying that it is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes and (y) an Internal Revenue Service Form W-8 or W-9, or successor applicable form, as the case may be, certifying that it is entitled to an exemption from United States backup withholding tax; (B) deliver to the Borrower and the Agent two further copies of any such form or certification on or before the date that any such form or certification expires or becomes obsolete and after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrower; and (C) obtain such extensions of time for filing and complete such forms or certifications as may reasonably be requested by the Borrower or the Agent; or

(ii) in the case of any such Lender that is not a “bank” within the meaning of Section 881(c)(3)(A) of the Internal Revenue Code, (A) represent to the Borrower (for the benefit of the Borrower and the Agent) that it is not a bank within the meaning of

31

Section 88l(c)(3)(A) of the Internal Revenue Code, (B) agree to furnish to the Borrower, on or before the date of any payment by the Borrower, with a copy to the Agent, two accurate and complete original signed copies of Internal Revenue Service Form W-8, or successor applicable form certifying to such Lender’s legal entitlement at the date of such certificate to an exemption from U.S. withholding tax under the provisions of Section 881(c) of the Internal Revenue Code with respect to payments to be made under this Agreement (and to deliver to the Borrower and the Agent two further copies of such form on or before the date it expires or becomes obsolete and after the occurrence of any event requiring a change in the most recently provided form and, if necessary, obtain any extensions of time reasonably requested by the Borrower or the Agent for filing and completing such forms), and (C) agree, to the extent legally entitled to do so, upon reasonable request by the Borrower, to provide to the Borrower (for the benefit of the Borrower and the Agent) such other forms as may be reasonably required in order to establish the legal entitlement of such Lender to an exemption from withholding with respect to payments under this Agreement.

Notwithstanding the above, if any change in treaty, law or regulation has occurred after the date such Person becomes a Lender hereunder which renders all such forms inapplicable or that would prevent such Lender from duly completing and delivering any such form with respect to it and such Lender so advises the Borrower and the Agent, then such Lender shall be exempt from such requirements. Each Person that shall become a Lender or a participant of a Lender pursuant to Section 11.3 shall, upon the effectiveness of the related transfer, be required to provide all of the forms, certifications and statements required pursuant to this subsection (b); provided that in the case of a participant of a Lender, the obligations of such participant of a Lender pursuant to this subsection (b) shall be determined as if the participant of a Lender were a Lender except that such participant of a Lender shall furnish all such required forms, certifications and statements to the Lender from which the related participation shall have been purchased.

SECTION 4.5. Replacement of Lenders.

The Agent and each Lender shall use reasonable efforts to avoid or mitigate any increased cost or suspension of the availability of an interest rate under Sections 4.1 through 4.4 above to the greatest extent practicable (including transferring the Advances to another lending office of Affiliate of a Lender) unless, in the opinion of the Agent or such Lender, such efforts would be likely to have an adverse effect upon it. In the event a Lender makes a request to the Borrower for additional payments in accordance with Section 4.1, 4.2 or 4.4, then, provided that no Default or Event of Default has occurred and is continuing at such time, the Borrower may, at its own expense (such expense to include any transfer fee payable to the Agent under Section 11.3(b) and any expense pursuant to Section 4) and in its sole discretion, require such Lender to transfer and assign in whole (but not in part), without recourse (in accordance with and subject to the terms and conditions of Section 11.3(b)), all of its interests, rights and obligations under this Agreement to an Eligible Assignee, which shall assume such assigned obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) such assignment shall not conflict with any law, rule or regulation or order of any court or other Governmental Authority and (ii) the Borrower or such assignee shall have paid to the assigning Lender in immediately available funds the principal of and interest accrued to the date

32

of such payment on the portion of the Advances hereunder held by such assigning Lender and all other amounts owed to such assigning Lender hereunder, including amounts owed pursuant to Sections 4.1 through 4.4.

SECTION 9.2. Acceleration; Remedies.

Upon the occurrence of an Event of Default, and at any time thereafter unless and until such Event of Default has been waived by the Required Lenders (or the Lenders as may be required hereunder) the Agent may, and shall, upon the request and direction of the Required Lenders, by written notice to the Borrower take any of the following actions without prejudice to the rights of the Agent or any Lender to enforce its claims against the Borrower, except as otherwise specifically provided for herein:

(a) Termination of the Commitments. Declare the Commitments terminated whereupon the Commitments shall be immediately terminated.

(b) Acceleration of Advances. Declare the unpaid amount of all Advances and all other amounts payable by the Borrower hereunder to be due whereupon the same shall be immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower.

(c) Enforcement of Rights. Enforce any and all rights and interests created and existing under the Credit Documents, including, without limitation, all rights of set-off.

(d) Cash Collateralization of LC Outstandings. Notwithstanding anything to the contrary contained herein, no notice given or declaration made by the Agent pursuant to this Article IX shall affect (i) the obligation of the Fronting Bank to make any payment under any Letter of Credit in accordance with the terms of such Letter of Credit or (ii) the obligations of each Lender in respect of each such Letter of Credit; provided, however, that if an Event of Default has occurred and is continuing, the Agent shall at the request, or may with the consent,

47

of the Required Lenders, upon notice to the Borrower, require the Borrower to deposit with the Agent an amount in the cash collateral account (the “Cash Collateral Account”) described below equal to the LC Outstandings on such date. Such Cash Collateral Account shall at all times be free and clear of all rights or claims of third parties. The Cash Collateral Account shall be maintained with the Agent in the name of, and under the sole dominion and control of, the Agent, and amounts deposited in the Cash Collateral Account shall bear interest at a rate equal to the rate generally offered by the Agent for deposits equal to the amount deposited by the Borrower in the Cash Collateral Account, for a term to be determined by the Agent, in its sole discretion. The Borrower hereby grants to the Agent for the benefit of the Fronting Bank and the Lenders a Lien in and hereby assigns to the Agent for the benefit of the Fronting Bank and the Lenders all of its right, title and interest in, the Cash Collateral Account and all funds from time to time on deposit therein to secure its reimbursement obligations in respect of Letters of Credit. If any drawings then outstanding or thereafter made are not reimbursed in full immediately upon demand or, in the case of subsequent drawings, upon being made, then, in any such event, the Agent may apply the amounts then on deposit in the Cash Collateral Account, toward the payment in full of any of the obligations as and when such obligations shall become due and payable. Upon payment in full, after the termination of the Letters of Credit, of all such obligations, the Agent will repay and reassign to the Borrower any cash then in the Cash Collateral Account and the Lien of the Agent on the Cash Collateral Account and the funds therein shall automatically terminate. In addition, at any time the Borrower is required under Section 2.8(c) or 3.2(b) to cash collateralize any of the LC Outstandings, the Borrower shall deposit such amount in the Cash Collateral Account. If, at any time no Event of Default has occurred and is continuing and the cash on deposit in the Cash Collateral Account shall exceed the LC Outstandings, then the Agent will repay and reassign to the Borrower cash in an amount equal to such excess, and the Lien of the Agent on such cash shall automatically terminate.

(e) Notwithstanding the foregoing, if an Event of Default specified in Section 9.1(e) shall occur, then the Commitments shall automatically terminate and all Advances, all accrued interest in respect thereof, all accrued and unpaid fees and other indebtedness or obligations owing to the Lenders and the Agent hereunder shall immediately become due and payable without the giving of any notice or other action by the Agent or the Lenders.

(f) Notwithstanding the fact that enforcement powers reside primarily with the Agent, each Lender has, to the extent permitted by law, a separate right of payment and shall be considered a separate “creditor” holding a separate “claim” within the meaning of Section 101(5) of the Bankruptcy Code or any other insolvency statute.

SECTION 9.3. Allocation of Payments After Event of Default.

Notwithstanding any other provisions of this Agreement, after the occurrence of an Event of Default, all amounts collected or received by the Agent or any Lender on account of amounts outstanding under any of the Credit Documents shall be paid over or delivered as follows:

FIRST, to the payment of all reasonable out-of-pocket costs and expenses (including without limitation reasonable attorneys’ fees) of the Agent or any of the Lenders in connection with enforcing the rights of the Lenders under the Credit Documents, pro rata as set forth below;

48

SECOND, to payment of any fees owed to the Agent or any Lender, pro rata as set forth below;

THIRD, to the payment of all accrued interest payable to the Lenders hereunder, pro rata as set forth below;

FOURTH, to the payment or cash collateralization, as applicable, of the Outstanding Credits, pro rata as set forth below;

FIFTH, to all other obligations that shall have become due and payable under the Credit Documents and not repaid pursuant to clauses “FIRST” through “THIRD” above; and

SIXTH, to the payment of the surplus, if any, to whoever may be lawfully entitled to receive such surplus.

In carrying out the foregoing, (i) amounts received shall be applied in the numerical order provided until exhausted prior to application to the next succeeding category; and (ii) each of the Lenders shall receive an amount equal to its pro rata share (based on the proportion that the then Outstanding Credits held by such Lender bears to the aggregate then outstanding Advances of amounts available to be applied.

SECTION 10.4. Reliance on Communications.

The Agent shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document or conversation believed by it in good faith to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Borrower, independent accountants and other experts selected by the Agent with reasonable care).

The Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders.

SECTION 10.6. Non-Reliance on Agent and Other Lenders.

Each Lender and the Fronting Bank expressly acknowledges that neither the Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates has made any representations or warranties to it and that no act by the Agent or any affiliate thereof hereinafter taken, including any review of the affairs of the Borrower, shall be deemed to constitute any representation or warranty by the Agent to any Lender or the Fronting Bank. Each Lender and the Fronting Bank represents to the Agent that it has, independently and without reliance upon the Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, assets, operations, property, financial and other conditions, prospects and creditworthiness of the Borrower and made its own decision to make its Extensions of Credit hereunder and enter into this Agreement. Each Lender and the Fronting Bank also represents that it will, independently and without reliance upon the Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement, and to make such investigation as it deems necessary to inform itself as to the business, assets, operations, property, financial and other conditions, prospects and creditworthiness of the Borrower. Except for notices, reports and other documents expressly required to be furnished to the Lenders and the Fronting Bank by the Agent hereunder, the Agent shall not have any duty or responsibility to provide any Lender or the Fronting Bank with any credit or other information concerning the business, operations, assets, property, financial or other conditions, prospects or creditworthiness of the Borrower that may come into the possession of the Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates.

51

disbursements of any kind whatsoever that may at any time (including without limitation at any time following the payment in full of the Advances and the other obligations of the Borrower hereunder) be imposed on, incurred by or asserted against the Agent in its capacity as such in any way relating to or arising out of this Agreement or the other Credit Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the gross negligence or willful misconduct of the Agent. If any indemnity furnished to the Agent for any purpose shall, in the opinion of the Agent, be insufficient or become impaired, the Agent may call for additional indemnity and cease, or not commence, to do the acts indemnified against until such additional indemnity is furnished. The agreements in this Section 10.7 shall survive the payment of the Advances and all other amounts payable hereunder.

SECTION 10.8. Agent in Its Individual Capacity.

The Agent in its individual capacity and its Affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Borrower as though the Agent were not Agent hereunder.

If no successor agent is appointed prior to the effective date of the resignation of the Agent, the Agent may appoint, after consulting with the Lenders and the Borrower, a successor agent from among the Lenders. Upon the acceptance of its appointment as successor agent hereunder, such successor agent shall succeed to all the rights, powers and duties of the retiring Agent, and the term “Agent” shall mean such successor agent and the retiring Agent’s appointment, powers and duties as Agent shall be terminated. After any retiring Agent’s resignation hereunder as Agent, the provisions of this Section 10 and Section 11.5 shall inure to its benefit as to any actions taken or omitted to be taken, by it while it was the Agent under this Agreement. If no successor agent has accepted appointment as the Agent by the date that is 30 days following a retiring Agent’s notice of resignation, the retiring Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above.

(i) each such assignment shall be to an Eligible Assignee;

53

(ii) except in the case of an assignment to another Lender, an Approved Fund of any Lender or an Affiliate of any Lender, or an assignment of all of a Lender’s rights and obligations under this Agreement, any such partial assignment shall be in an amount at least equal to $5,000,000 (or, if less, the remaining amount of the Commitment being assigned by such Lender) and an integral multiple of $1,000,000 in excess thereof;

(iii) each such assignment by a Lender shall be of a constant and not varying, percentage of all of its rights and obligations under this Agreement; and

(iv) the parties to such assignment shall execute and deliver to the Agent for its acceptance an Assignment Agreement together with a processing fee (other than in connection with any assignment to a Lender, an Approved Fund of any Lender or an Affiliate of such Lender) from the assignor of $3,500.

Upon execution, delivery, and acceptance of such Assignment Agreement, the assignee thereunder shall be a party hereto and, to the extent of such assignment, have the obligations, rights, and benefits of a Lender hereunder and the assigning Lender shall, to the extent of such assignment, relinquish its rights and be released from its obligations under this Agreement. Upon the consummation of any assignment pursuant to this subsection (b), the assignor, the Agent and the Borrower shall make appropriate arrangements so that, if required, new promissory notes are issued to the assignor and the assignee. If the assignee is not incorporated under the laws of the United States of America or a state thereof, it shall deliver to the Borrower and the Agent certification as to exemption from deduction or withholding of taxes in accordance with Section 4.4.

By executing and delivering an Assignment Agreement in accordance with this subsection (b), the assigning Lender thereunder and the assignee thereunder shall be deemed to confirm to and agree with each other and the other parties hereto as follows: (A) such assigning Lender represents and warrants that it is legally authorized to enter into such Assignment Agreement and it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim created by such assigning Lender and the assignee warrants that it is an Eligible Assignee; (B) except as set forth in clause (A) above, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto, or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto or the financial condition of the Borrower or the performance or observance by the Borrower of any of its obligations under this Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto; (C) such assignee represents and warrants that it is legally authorized to enter into such Assignment Agreement; (D) such assignee confirms that it has received a copy of this Agreement, the other Credit Documents and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment Agreement; (E) such assignee will independently and without reliance upon the Agent, such assigning Lender or any other Lender, 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

54

action under this Agreement and the other Credit Documents; (F) such assignee appoints and authorizes the Agent to take such action on its behalf and to exercise such powers under this Agreement or any other Credit Document as are delegated to the Agent by the terms hereof or thereof, together with such powers as are reasonably incidental thereto; and (G) such assignee agrees that it will perform in accordance with their terms all the obligations that by the terms of this Agreement and the other Credit Documents are required to be performed by it as a Lender.

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

(d) Acceptance. Upon its receipt of an Assignment Agreement executed by the parties thereto, together with and payment of the processing fee, the Agent shall, if such Assignment Agreement has been completed and is in substantially the form of Exhibit D hereto, (i) accept such Assignment Agreement, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the parties thereto.

(e) Participations. Each Lender may sell participations to one or more Persons in all or a portion of its rights, obligations or rights and obligations under the Credit Documents (including all or a portion of its Commitment and its Advances); provided, however, that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the participant shall be entitled to the benefit of the yield protection provisions contained in Sections 4.1 through 4.4, inclusive, and the right of set-off contained in Section 11.2, and (iv) the Borrower shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement, and such Lender shall retain the sole right to enforce the obligations of the Borrower relating to its Advances and to approve any amendment, modification, or waiver of any provision of this Agreement (other than amendments, modifications, or waivers decreasing the amount of principal of or the rate at which interest is payable on such Advances, extending any principal payment date or date fixed for the payment of interest on such Advances, or extending its Commitment).

(f) Nonrestricted Assignments. Notwithstanding any other provision set forth in this Agreement:

(i) any Lender may at any time, without the consent of the Borrower or the Agent, assign all or any portion of its rights under the Credit Documents to any Federal Reserve Bank as security. No such assignment shall release the assigning Lender from its obligations hereunder;

(ii) any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”) of such Granting Lender identified as such in writing from time to

55

time by the Granting Lender to the Agent and the Borrower, the option to provide to the Borrower all or any part of any Extension of Credit that such Granting Lender would otherwise be obligated to make to such Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any such SPC to make any Extension of Credit, (ii) if such SPC elects not to exercise such option or otherwise fails to provide all or any part of such Extension of Credit, the Granting Lender shall be obligated to make such Extension of Credit pursuant to the terms hereof and (iii) no SPC or Granting Lender shall be entitled to receive any greater amount pursuant to Section 4.1(c) or 4.4 than the Granting Lender would have been entitled to receive had the Granting Lender not otherwise granted such SPC the option to provide any Extension of Credit to the Borrower. The making of an Extension of Credit by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Extension of Credit were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender would otherwise be liable so long as, and to the extent that, the related Granting Lender provides such indemnity or makes such payment. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against or join any other person in instituting against such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. Notwithstanding the foregoing, the Granting Lender unconditionally agrees to indemnify the Borrower, the Agent, the Fronting Bank and each Lender against all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be incurred by or asserted against the Borrower, the Agent, the Fronting Bank or such Lender, as the case may be, in any way relating to or arising as a consequence of any such forbearance or delay in the initiation of any such proceeding against its SPC. Each party hereto hereby acknowledges and agrees that no SPC shall have the rights of a Lender hereunder, such rights being retained by the applicable Granting Lender. Accordingly, and without limiting the foregoing, each party hereby further acknowledges and agrees that no SPC shall have any voting rights hereunder and that the voting rights attributable to any Extension of Credit made by an SPC shall be exercised only by the relevant Granting Lender and that each Granting Lender shall serve as the administrative agent and attorney-in-fact for its SPC and shall on behalf of its SPC receive any and all payments made for the benefit of such SPC and take all actions hereunder to the extent, if any, such SPC shall have any rights hereunder. In addition, notwithstanding anything to the contrary contained in this Agreement, any SPC may (i) with notice to, but without the prior written consent of any other party hereto, assign all or a portion of its interest in any Extension of Credit to the Granting Lender and (ii) disclose on a confidential basis any information relating to its Extensions of Credit to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This Section may not be amended without the prior written consent of each Granting Lender, all or any part of whose Extension of Credit is being funded by an SPC at the time of such amendment; and

56

(iii) any Lender at any time may assign all or any portion of its rights and obligations under this Agreement to any Affiliate or Approved Fund of such Lender, provided such assignment does not result in the incurrence of any increased payment obligations by any Borrower under Section 4.2 or 4.4. Upon execution, delivery, and acceptance of such Assignment Agreement, the assignee thereunder shall be a party hereto and, to the extent of such assignment, have the obligations, rights, and benefits of a Lender hereunder and the assigning Lender shall, to the extent of such assignment, relinquish its rights and be released from its obligations under this Agreement. If the assignee is not incorporated under the laws of the United States of America or a state thereof, it shall deliver to the Borrower and the Agent certification as to exemption from deduction or withholding of taxes in accordance with Section 4.4.

(g) Information. Any Lender may furnish any information concerning the Borrower in the possession of such Lender from time to time to assignees and participants (including prospective assignees and participants) or to any party that such Lender has engaged or proposes to engage in any swap, securitization or derivative transaction involving any of such Lender’s rights or obligations hereunder.

SECTION 11.4. No Waiver; Remedies Cumulative.

No failure or delay on the part of the Agent, the Fronting Bank or any Lender in exercising any right, power or privilege hereunder or under any other Credit Document and no course of dealing between the Borrower and the Agent, the Fronting Bank or any Lender shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege hereunder or under any other Credit Document preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. The rights and remedies provided herein are cumulative and not exclusive of any rights or remedies that the Agent, the Fronting Bank or any Lender would otherwise have. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Agent, the Fronting Bank or the Lenders to any other or further action in any circumstances without notice or demand.

SECTION 11.5. Payment of Expenses, etc.

The Borrower agrees to: (i) pay all reasonable out-of-pocket costs and expenses of the Agent in connection with (A) the negotiation, preparation, execution and delivery and administration of this Agreement and the other Credit Documents and the documents and instruments referred to therein (including, without limitation, legal fees of the Agent) and (B) any amendment, waiver or consent relating hereto and thereto including, but not limited to, any such amendments, waivers or consents resulting from or related to any work-out, renegotiation or restructure relating to the performance by the Borrower under this Agreement; (ii) pay all reasonable out-of-pocket costs and expenses of the Agent, the Fronting Bank and the Lenders in connection with (A) enforcement of the Credit Documents and the documents and instruments referred to therein (including, without limitation, in connection with any such enforcement, the reasonable fees and disbursements of counsel for the Agent, the Fronting Bank and each of the Lenders) and (B) any bankruptcy or insolvency proceeding of the Borrower; and

57

(iii) indemnify the Agent, the Fronting Bank and each Lender, its affiliates, officers, directors, employees, advisors and agents from and hold each of them harmless against any and all losses, liabilities, claims, damages or expenses incurred by any of them as a result of, or arising out of, or in any way related to, or by reason of, any investigation, litigation or other proceeding (whether or not the Agent or any Lender is a party thereto) related to the entering into and/or performance of any Credit Document or the use of proceeds of any Extension of Credit hereunder or the consummation of any other transactions contemplated in any Credit Document, including, without limitation, the reasonable fees and disbursements of counsel incurred in connection with any such investigation, litigation or other proceeding (but excluding any such losses, liabilities, claims, damages or expenses to the extent incurred by reason of gross negligence or willful misconduct on the part of the Person to be indemnified). Such expenses shall be reimbursed by the Borrower upon presentation of a statement of account, which statement shall be conclusive absent manifest error.

SECTION 11.6. Amendments, Waivers and Consents.

Neither this Agreement, nor any other Credit Document nor any of the terms hereof or thereof may be amended, changed, waived, discharged or terminated unless such amendment, change, waiver, discharge or termination is in writing and signed by the Required Lenders and the Borrower; provided that no amendment, waiver or consent shall, unless in writing and signed by the Fronting Bank in addition to the Required Lenders and the Borrower, affect the rights or duties of the Fronting Bank under this Agreement or any other Credit Document, and provided further, that no such amendment, change, waiver, discharge or termination shall without the consent of each Lender affected thereby:

(a) extend the Maturity Date, or postpone or extend the time for any payment or prepayment of principal, except as provided in Section 2.7;

(b) reduce the rate or extend the time of payment of interest (other than as a result of waiving the applicability of any post-default increase in interest rates) thereon or fees or other amounts payable hereunder;

(c) reduce or waive the principal amount of any Advance;

(d) increase or extend the Commitment (it being understood and agreed that a waiver of any Default or Event of Default shall not constitute a change in the terms of any Commitment of any Lender);

(e) release the Borrower from its obligations under the Credit Documents;

(f) amend, modify or waive any provision of this Section 11.6 or Section 3.6, 3.8, 4.1, 4.2, 4.3, 4.4, 9.1(a), 11.2, 11.3 or 11.5;

(g) reduce any percentage specified in, or otherwise modify, the definition of Required Lenders; or

(h) consent to the assignment or transfer by the Borrower of any of its rights and obligations under (or in respect of) the Credit Documents.

58

Notwithstanding the foregoing, this Agreement may be amended and restated without the consent of any Lender or the Agent if, upon giving effect to such amendment and restatement, such Lender or the Agent, as the case may be, shall no longer be a party to this Agreement (as so amended and restated) or have any Commitment or other obligation hereunder and shall have been paid in full all amounts payable hereunder to such Lender or the Agent, as the case may be. No provision of Section 10 may be amended or modified without the consent of the Agent.

Notwithstanding the fact that the consent of all the Lenders is required in certain circumstances as set forth above, each Lender is entitled to vote as such Lender sees fit on any reorganization plan that affects the Extensions of Credit, and each Lender acknowledges that the provisions of Section 1126(c) of the Bankruptcy Code supersedes the unanimous consent provisions set forth herein.

SECTION 11.7. Counterparts/Telecopy.

This Agreement may be executed in any number of counterparts, each of which where so executed and delivered shall be an original, but all of which shall constitute one and the same instrument. Delivery of executed counterparts by telecopy shall be as effective as an original and shall constitute a representation that an original will be delivered.

SECTION 11.8. Headings.

The headings of the Sections and subsections hereof are provided for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement.

SECTION 11.9. Defaulting Lender.

Each Lender understands and agrees that if such Lender is a Defaulting Lender then it shall not be entitled to vote on any matter requiring the consent of the Required Lenders or to object to any matter requiring the consent of all the Lenders; provided, however, that all other benefits and obligations under the Credit Documents shall apply to such Defaulting Lender.

SECTION 11.10. Confidentiality.

Each of the Agent, each Lender and the Fronting Bank agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed by such Person (i) to its Affiliates and to its and its Affiliates’ respective partners, directors, officers, employees, agents, advisors and other representatives (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (ii) to the extent requested by any regulatory authority purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (iii) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (iv) to any other party hereto, (v) in connection with the exercise of any remedies hereunder or under any other Credit Document or any action or proceeding relating to this Agreement or any other Credit Document or the enforcement of rights hereunder or thereunder, (vi) subject to an agreement containing provisions substantially the same as those of this Section, to (A) any assignee of or participant, or any prospective assignee of or participant in, any of its rights or

59

obligations under this Agreement or (B) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower and its obligations, (vii) with the consent of the Borrower or (viii) to the extent such Information (A) becomes publicly available other than as a result of a breach of this Section or (B) becomes available to the Agent, any Lender, the Fronting Bank or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrower. Notwithstanding anything in this Agreement to the contrary, the Borrower, the Agent, the Fronting Bank and each Lender (and each officer, director, employee, agent and advisor of each such Person) shall not be limited from disclosing the US tax treatment or the US tax structure of the transactions contemplated hereby. For purposes of this Section, “Information” means all information received from the Borrower or any of its Subsidiaries relating to the Borrower or any of its Subsidiaries or any of their respective businesses, other than any such information that is available to the Agent, any Lender or the Fronting Bank on a nonconfidential basis prior to disclosure by the Borrower or any of its Subsidiaries, provided that, in the case of information received from the Borrower or any of its Subsidiaries after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

SECTION 11.11. Survival of Indemnification and Representations and Warranties.

All indemnities set forth herein and all representations and warranties made herein shall survive the execution and delivery of this Agreement, the making of Extensions of Credit and the repayment of the Borrowings and other obligations and the termination of the Commitments hereunder.

SECTION 11.12. Governing Law; Venue.

(a) THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

Nothing herein shall affect the right of a Lender to serve process in any other manner permitted by law or to commence legal proceedings or to otherwise proceed against the Borrower in any other jurisdiction.

(b) All parties hereto hereby irrevocably waive any objection that each may now or hereafter have to the laying of venue of any of the aforesaid actions or proceedings arising out of

60

or in connection with this Agreement or any other Credit Document brought in the courts referred to in subsection (i) hereof and hereby further irrevocably waive and agree not to plead or claim in any such court that any such action or proceeding brought in any such court has been brought in an inconvenient forum.

SECTION 11.13. Waiver of Jury Trial; Waiver of Consequential Damages.

EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OF THE OTHER CREDIT DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY. THE BORROWER AGREES NOT TO ASSERT ANY CLAIM AGAINST THE AGENT, THE FRONTING BANK, ANY LENDER, ANY OF THEIR SUBSIDIARIES, AFFILIATES, OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, ATTORNEYS OR AGENTS, ON ANY THEORY OF LIABILITY, FOR SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES ARISING OUT OF OR OTHERWISE RELATING TO ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN.

SECTION 11.16. Assurances.

The Borrower agrees, upon the request of the Agent, to promptly take such actions, as reasonably requested, as are necessary to carry out the intent of this Agreement and the other Credit Documents.

NOW, THEREFORE, in consideration of the premises and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

ARTICLE I

DEFINITIONS AND ACCOUNTING TERMS

SECTION 1.1. Definitions.

As used herein, the following terms shall have the meanings herein specified unless the context otherwise requires. Defined terms herein shall include in the singular number the plural and in the plural the singular:

“Advance” means an advance by a Lender to the Borrower as part of a Borrowing and refers to a Base Rate Advance or a Eurodollar Advance.

“Affiliate” means, with respect to any Person, any other Person directly or indirectly controlling (including but not limited to all directors and officers of such Person), controlled by or under direct or indirect common control with such Person. A Person shall be deemed to control a corporation if such Person possesses, directly or indirectly, the power (i) to vote 10% or more of the securities having ordinary voting power for the election of directors of such corporation or (ii) to direct or cause direction of the management and policies of such corporation, whether through the ownership of voting securities, by contract or otherwise.

“Agent” has the meaning ascribed to such term in the preamble hereto.

“Agreement” has the meaning ascribed to such term in the preamble hereto.

“Applicable Margin” means, with respect to Base Rate Advances, 0.0% per annum and, with respect to Eurodollar Advances, the amount per annum set forth below in the column

identified by the Applicable Rating Level at the time of determination. The Applicable Margin shall increase by an amount equal to the Utilization Fee set forth below (the “Utilization Fee”) during any period (and for only such period) in which more than 50% of the Commitments are utilized. Upon the occurrence and during the continuance of any Event of Default, the Applicable Margin shall increase by 2.0% per annum, and if any Advance is a Eurodollar Advance, it will convert to a Base Rate Advance at the end of the Interest Period then in effect for such Eurodollar Advance.

Applicable Rating Level	Level 1	Level 2	Level 3	Level 4	Level 5	Level 6	Level 7
Applicable Margin	0.11%	0.15%	0.19%	0.23%	0.26%	0.35%	0.50%
Utilization Fee	0.05%	0.05%	0.05%	0.05%	0.05%	0.10%	0.10%

Any change in the Applicable Margin shall be effective on the date on which Moody’s, S&P or Fitch, as the case may be, announces any change in any rating that results in a change in the Applicable Rating Level.

“Applicable Rating Level” means, at any time, the number set forth below in the row next to the then-applicable ratings by S&P, Moody’s and Fitch, respectively, of the Borrower’s long-term senior unsecured debt.

Moody’s Rating S&P Rating Fitch Rating	Applicable Rating Level
At least Aa3, at least AA- and at least AA-	1

Notwithstanding the foregoing, if the Borrower shall (i) fail to maintain a rating of its senior unsecured debt by at least two of Moody’s, S&P and Fitch, Level 7 shall be the pricing level; (ii) maintain a rating of its senior unsecured debt from only two of Moody’s, S&P and Fitch and (A) there is a difference of one level in such ratings, then the higher of such ratings shall be used to determine the Applicable Rating Level, or (B) there is a difference of more than one level in such ratings, then the rating that is one level below the higher of such ratings shall be used to determine the Applicable Rating Level; and (iii) maintain a rating of its senior unsecured debt from all three of Moody’s, S&P and Fitch and there is a difference in such ratings such that (A) two of such ratings fall in the same Applicable Rating Level and are higher than the third, then the higher of such ratings will be used to determine the Applicable Rating Level, (B) two of such ratings fall in the same Applicable Rating Level and are lower than the third, then the lower of such ratings will be used to determine the Applicable Rating Level, and (C) all three such ratings fall in different Applicable Rating Levels, then the intermediate rating will be used to determine the Applicable Rating Level.

“Approved Fund” means with respect to any Lender that is a fund that invests in bank loans, any other fund that invests in commercial loans and is managed or advised by the same investment advisor as such Lender or by an Affiliate of such investment advisor.

(ii) 1/2 of 1% per annum above the Federal Funds Rate.

If for any reason the Agent shall have determined (which determination shall be conclusive absent manifest error) that it is unable after due inquiry to ascertain the Federal Funds Rate for any reason, including the inability or failure of the Agent to obtain sufficient quotations in accordance with the terms hereof, the Base Rate shall be determined without regard to clause (ii) of the first sentence of this definition until the circumstances giving rise to such inability no longer exist. Any change in the Base Rate due to a change in U.S. Bank’s base rate or the Federal Funds Rate shall be effective on the effective date of such change in the base rate or the Federal Funds Rate, as the case may be.

“Base Rate Advance” means an Advance that bears interest based on the Base Rate.

3

ARTICLE II

THE COMMITMENTS AND THE EXTENSIONS OF CREDIT

SECTION 2.1. The Commitments.

Subject to the terms and conditions set forth herein, each Lender severally agrees to make Advances to the Borrower in Dollars, at any time and from time to time prior to the Maturity Date, in an amount not to exceed at any time such Lender’s Commitment, the Fronting Bank agrees to issue Letters of Credit for the account of the Borrower at any time and from time to time until the fifth Business Day preceding the Maturity Date in an aggregate stated amount at any time outstanding not to exceed the LC Commitment Amount, and each Lender agrees to purchase participations in such Letters of Credit as more fully set forth in Section 2.8; provided, however, that (i) the aggregate amount of Outstanding Credits shall not exceed the aggregate Commitments and (ii) with respect to each individual Lender, such Lender’s pro rata share of Outstanding Credits shall not exceed such Lender’s Commitment Percentage of the aggregate Commitments. Subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow Advances.

SECTION 2.2. Method of Borrowing.

By no later than 11:00 a.m. (i) on the date of the requested Borrowing that will comprise Base Rate Advances or (ii) three Business Days prior to the date of the requested Borrowing that will comprise Eurodollar Advances, the Borrower shall submit to the Agent a written Notice of Borrowing in the form of Exhibit A setting forth (A) the amount requested, (B) whether such Advances shall accrue interest at the Base Rate or the Eurodollar Rate, (C) with respect to Borrowings that will comprise Eurodollar Advances, the Interest Period applicable thereto, and (D) certification that the Borrower has complied in all respects with Section 5.2.

16

SECTION 2.3. Funding of Borrowings.

(a) Upon receipt of a Notice of Borrowing, the Agent shall promptly inform the Lenders as to the terms thereof. Each such Lender shall make its Commitment Percentage of the requested Borrowing available to the Agent by 1:00 p.m. on the date specified in the Notice of Borrowing by deposit, in Dollars, of immediately available funds at the principal offices of the Agent in Milwaukee, Wisconsin or at such other address as the Agent may designate in writing. The amount of the requested Borrowing will then be made available to the Borrower by the Agent by crediting the account of the Borrower on the books of such office of the Agent, to the extent the amount of such Borrowing is made available to the Agent.

(b) No Lender shall be responsible for the failure or delay by any other Lender in its obligation to make Advances hereunder; provided, however, that the failure of any Lender to fulfill its obligations hereunder shall not relieve any other Lender of its obligations hereunder. Unless the Agent shall have been notified by any Lender prior to the date of any such Borrowing (in the case of a Eurodollar Borrowing) or the time of any such Borrowing (in the case of a Base Rate Borrowing) that such Lender does not intend to make available to the Agent its portion of the Borrowing to be made on such date, the Agent may assume that such Lender has made such amount available to the Agent on the date of such Borrowing, and the Agent in reliance upon such assumption, may (in its sole discretion but without any obligation to do so) make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the Agent, the Agent shall be able to recover such corresponding amount from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Agent’s demand therefor, the Agent will promptly notify the Borrower, and the Borrower shall immediately pay such corresponding amount to the Agent. The Agent shall also be entitled to recover from the Lender or the Borrower, as the case may be, interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the Agent to the Borrower to the date such corresponding amount is recovered by the Agent at a per annum rate equal to, (i) if from the Borrower, the applicable rate for such Advance pursuant to the Notice of Borrowing and (ii) if from a Lender, the Federal Funds Rate.

SECTION 2.4. Continuations and Conversions.

The Borrower shall have the option, on any Business Day, to continue existing Eurodollar Advances for a subsequent Interest Period, to convert Base Rate Advances into Eurodollar Advances or to convert Eurodollar Advances into Base Rate Advances; provided, however, that (i) each such continuation or conversion must be requested by the Borrower pursuant to a written Notice of Continuation/Conversion, in the form of Exhibit B, in compliance with the terms set forth below, (ii) except as provided in Section 4.1, Eurodollar Advances may be continued or converted into Base Rate Advances only on the last day of the Interest Period applicable hereto, (iii) Eurodollar Advances may not be continued nor may Base Rate Advances be converted into Eurodollar Advances during the existence and continuation of a Default or Event of Default and (iv) any request to extend a Eurodollar Advance that fails to comply with the terms hereof or any failure to request an extension of a Eurodollar Advance that fails to comply with the terms hereof or any failure to request an extension of a Eurodollar Advance at the end of an Interest Period shall constitute a conversion to a Base Rate Advance on the last day of the applicable Interest Period. Each continuation or conversion must be requested by the

17

Borrower no later than 11:00 a.m. (A) on the date for a requested conversion of a Eurodollar Advance to a Base Rate Advance or (B) three Business Days prior to the date for a requested continuation of a Eurodollar Advance or conversion of a Base Rate Advance to a Eurodollar Advance, in each case pursuant to a written Notice of Continuation/Conversion submitted to the Agent, which shall set forth (1) whether the Borrower wishes to continue or convert such Advances and (2) if the request is to continue a Eurodollar Advance or convert a Base Rate Advance to a Eurodollar Advance, the Interest Period applicable thereto.

SECTION 2.5. Minimum Amounts.

Each request for a Borrowing or a conversion or continuation hereunder shall be subject to the following requirements: (i) each Borrowing consisting of Eurodollar Advances shall be in a minimum of $5,000,000 (and in integral multiples of $1,000,000 in excess thereof); (ii) each Borrowing consisting of Base Rate Advances shall be in a minimum amount of the lesser of $500,000 (and in integral multiples of $500,000 in excess thereof) and the remaining amount available to be borrowed; and (iii) no more than ten Eurodollar Borrowings shall be outstanding hereunder at any one time. For the purposes of this Section, all Eurodollar Borrowings with the same Interest Periods that begin and end on the same date shall be considered as one Eurodollar Borrowing, but Eurodollar Borrowings with different Interest Periods, even if they begin on the same date, shall be considered separate Eurodollar Borrowings.

SECTION 2.6. Reduction of the Commitments.

Upon at least five Business Days’ notice, the Borrower shall have the right to permanently terminate or reduce the aggregate unused amount of the Commitments at any time or from time to time; provided that each partial reduction shall be in an aggregate amount at least equal to $5,000,000 and in integral multiples of $1,000,000 above such amount and no reduction shall be made that would reduce the Commitments to an amount less than the then Outstanding Credits. Any reduction in (or termination of) the Commitments shall be permanent and may not be reinstated.

SECTION 2.7. Extension of Maturity Date.

(a) Not earlier than 45 days prior to, nor later than 30 days prior to, the then-effective Maturity Date, the Borrower may request by Requisite Notice (as defined below) made to the Agent (which shall promptly notify the Lenders) a one-year extension of the Maturity Date. Such request shall include a certificate signed by a Responsible Officer (as defined below) stating that (i) the representations and warranties contained in Article VI are true and correct on and as of the date of such certificate and (ii) no Default or Event of Default has occurred and is continuing. Each Lender shall notify the Agent by Requisite Notice by the date specified by the Agent (which date shall be a Business Day and shall not be less than 15 Business Days prior to, nor more than 30 days prior to, the then Maturity Date) that either (A) such Lender declines to consent to extending the Maturity Date or (B) such Lender consents to extending the Maturity Date. Any Lender not responding within the above time period shall be deemed not to have consented to extending the Maturity Date. The Agent shall, after receiving the notifications from all of the Lenders or the expiration of such period, whichever is earlier, notify the Borrower and the Lenders of the results thereof. The Borrower may request no more than two extensions pursuant to this Section.

18

(b) If any Lender declines, or is deemed to have declined, to consent to such request for extension (a “Declining Lender”), provided that (i) no Default or Event of Default has occurred and is continuing at such time and (ii) the Required Lenders are non-Declining Lenders, the Borrower may, at its own expense (such expense to include any transfer fee payable to the Agent under Section 11.3(b) and any expense pursuant to Section 4.3) and in its sole discretion, require such Declining Lender to transfer and assign in whole (but not in part) without recourse (in accordance with and subject to the terms and conditions of Section 11.3(b)) all of its interests, rights and obligations under this Agreement to an Eligible Assignee, which shall assume such assigned obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (A) such assignment shall not conflict with any law, rule or regulation or order of any court or other Governmental Authority and (B) the assigning Declining Lender shall have received in immediately available funds the principal of and interest accrued to the date of such payment on the portion of the Advances hereunder held by such assigning Declining Lender and all other amounts owed to such assigning Declining Lender hereunder, including amounts owed pursuant to Sections 4.1 through 4.4.

(c) If the conditions set forth in subsection (b) above have been satisfied, the Maturity Date shall be extended (solely with respect to the non-Declining Lenders) to the date that is one year after the then-effective Maturity Date, effective as of the date to be determined by the Agent and the Borrower (the “Maturity Extension Decision Date”), and the Agent shall promptly notify the Lenders thereof. On or prior to the Maturity Extension Decision Date, the Borrower shall deliver to the Agent, in form and substance satisfactory to the Agent and the Lenders (i) the resolutions of the Board of Directors of the Borrower authorizing such extension, certified as in effect as of the Maturity Extension Decision Date and the related incumbency certificate of the Borrower, (ii) new or amended promissory notes, if requested by any new or affected Lender, evidencing the new or revised Commitment of such Lender, (iii) a certificate of the Borrower stating that on and as of such Maturity Extension Decision Date, and after giving effect to the extension to be effective on such date, (A) the representations and warranties set forth in Article VI are true and correct and (B) no Default or Event of Default is continuing. The Agent shall distribute an amended Schedule I to this Agreement (which shall thereafter be incorporated into this Agreement), to reflect any changes in Lenders, the Commitments and each Lender’s Commitment Percentage.

(d) For purposes of this Section:

(i) “Responsible Officer” means the chairman of the board, chief executive officer, president, chief financial officer, treasurer, or assistant treasurer of the Borrower. Any document or certificate hereunder that is signed by a Responsible Officer shall be conclusively presumed to have been authorized by all necessary corporate action on the part of the Borrower and such Responsible Officer shall be conclusively presumed to have acted on behalf of the Borrower.

(ii) “Requisite Notice” means irrevocable written notice to the intended recipient or irrevocable telephonic notice to the intended recipient, immediately followed

19

by a written notice to such recipient. Such notices shall be (i) delivered to such recipient at the address or telephone number specified on Schedule II or as otherwise designated by such recipient by Requisite Notice to each other party hereto, and (ii) if made by the Borrower, given or made by a Responsible Officer. Any written notice delivered shall be delivered as provided in Section 11.1. Any notice sent by other than hardcopy shall be promptly confirmed by a telephone call to the recipient and, if requested by the Agent, by a manually-signed hardcopy thereof.

SECTION 2.8. Letters of Credit.

(a) Subject to the terms and conditions hereof, the Fronting Bank agrees to issue Letters of Credit from time to time for the account of the Borrower (or to extend the stated maturity thereof or to modify or amend the terms thereof) for the purposes set forth in Section 7.9 on not less than five Business Days’ prior notice thereof by delivery of a Request for Issuance to the Agent (which shall promptly distribute copies thereof to the Lenders) and the Fronting Bank. Each Request for Issuance shall specify (i) the date (which shall be a Business Day) of issuance of such Letter of Credit (or the date of effectiveness of such extension, modification or amendment) and the stated expiry date thereof (which shall be no later than one year following the date of such issuance), (ii) the proposed stated amount of such Letter of Credit, (iii) the name and address of the beneficiary of such Letter of Credit and (iv) a statement of drawing conditions applicable to such Letter of Credit, and if such Request for Issuance relates to an amendment or modification of a Letter of Credit, it shall be accompanied by the consent of the beneficiary of the Letter of Credit thereto. Each Request for Issuance shall be irrevocable unless modified or rescinded by the Borrower not less than two Business Days prior to the proposed date of issuance (or effectiveness) specified therein. Not later than 12:00 noon (Milwaukee, Wisconsin time) on the proposed date of issuance (or effectiveness) specified in such Request for Issuance, and upon fulfillment of the applicable conditions precedent and the other requirements set forth herein, the Fronting Bank shall issue (or extend, amend or modify) such Letter of Credit and provide notice and a copy thereof to the Agent, which shall promptly furnish copies thereof to the Lenders. The Fronting Bank shall provide to the Agent, on a monthly basis, a list of the amounts and expiration dates of all undrawn Letters of Credit, a copy of which list the Agent shall furnish to each Lender that requests such list.

(b) No Letter of Credit shall be requested or issued hereunder if, after the issuance thereof, (i) the Outstanding Credits would exceed the aggregate Commitments or (ii) the LC Outstandings would exceed the LC Commitment Amount.

(c) In the event that any Letter of Credit remains outstanding beyond the fifteenth day prior to the Maturity Date, the Borrower shall either (i) pay to the Agent an amount equal to 103% of the LC Outstandings on the later of such date and the date of issuance of such Letter of Credit, which amount the Agent shall hold in the Cash Collateral Account for the account of the Borrower, without interest, for the purpose of paying any draft presented, with the excess, if any, to be returned to the Borrower upon termination or expiration of such Letter of Credit and payment in full of all amounts due hereunder or (ii) deliver a back-up letter of credit to the Agent securing the Borrower’s reimbursement obligations with respect to such Letter of Credit in form and substance acceptable to the Fronting Bank and the Agent and from a creditworthy financial institution acceptable to the Agent. While any Letter of Credit is outstanding, the Agent may not release funds held in the Cash Collateral Account pursuant to this subsection (c) without the consent of all Lenders.

20

(d) Each Lender, upon issuance of a Letter of Credit, shall be deemed to have purchased without recourse a participation from the Fronting Bank in such Letter of Credit and the rights and obligations arising thereunder and any collateral relating thereto, in each case in an amount equal to such Lender’s Commitment Percentage of the obligations under such Letter of Credit, and shall absolutely, unconditionally and irrevocably assume, as primary obligor and not as surety, and be obligated to pay to the Fronting Bank therefor and discharge when due, such Lender’s Commitment Percentage of the obligations arising under such Letter of Credit. Without limiting the scope and nature of each Lender’s participation in any Letter of Credit, to the extent that the Fronting Bank has not been reimbursed as required hereunder or under any such Letter of Credit, each Lender shall pay to the Fronting Bank its Commitment Percentage of such unreimbursed drawing in same day funds on the day of notification by the Fronting Bank of an unreimbursed drawing pursuant to the provisions of subsection (e). The obligation of each Lender so to reimburse the Fronting Bank shall be absolute and unconditional and shall not be affected by the occurrence of a Default, an Event of Default or any other occurrence or event. Any such reimbursement shall not relieve or otherwise impair the obligation of the Borrower to reimburse the Fronting Bank under any Letter of Credit, together with interest as hereinafter provided.

(e) In the event of any drawing under any Letter of Credit, the Fronting Bank will promptly notify the Borrower. Unless the Borrower shall immediately notify the Fronting Bank of its intent otherwise to reimburse the Fronting Bank for any drawing made prior to the Maturity Date, the Borrower shall be deemed to have requested a Base Rate Advance in the amount of such drawing as provided in subsection (f), the proceeds of which will be used to satisfy the reimbursement obligation of the Borrower with respect to such drawing. If, at any time on or after the Maturity Date, any drawing is made under any Letter of Credit, the Fronting Bank shall instruct the Agent to withdraw from the Cash Collateral Account funds in an amount equal to the amount of such drawing, which the Agent shall transfer to the Fronting Bank in order to reimburse the Fronting Bank for such drawing. In the case of any drawing made under any Letter of Credit prior to the Maturity Date, the Borrower shall reimburse the Fronting Bank on the day such drawing is paid either with the proceeds of an Advance obtained hereunder or otherwise in same day funds as provided herein. If the Borrower shall fail to reimburse the Fronting Bank as provided herein, the unreimbursed amount of such drawing shall bear interest at a per annum rate equal to the Base Rate plus two percent (2%) per annum. The Borrower’s reimbursement obligations hereunder shall be absolute and unconditional under all circumstances irrespective of any rights of set-off, counterclaim or defense to payment that the applicable account party or the Borrower may claim or have against the Fronting Bank, the Lenders, the beneficiary of the Letter of Credit drawn upon or any other Person, including, without limitation, any defense based on any failure of the applicable account party or the Borrower to receive consideration or the legality, validity, regularity or unenforceability of the Letter of Credit. The Fronting Bank will promptly notify the Lenders of the amount of any unreimbursed drawing and each Lender shall promptly pay to the Fronting Bank, in immediately available funds, the amount of such Lender’s Commitment Percentage of such unreimbursed drawing. Such payment shall be made on the day such notice is received by such Lender from the Fronting Bank if such notice is received at or before 2:00 p.m., otherwise such payment shall be made at or before

21

12:00 noon on the Business Day next succeeding the day such notice is received. If such Lender does not pay such amount to the Fronting Bank in full upon such request, such Lender shall, on demand, pay to the Fronting Bank interest on the unpaid amount during the period from the date the Lender received the notice regarding the unreimbursed drawing until the Lender pays such amount to the Fronting Bank in full at a rate per annum equal to, if paid within two Business Days of the date of drawing, the Federal Funds Rate and thereafter at a rate equal to the Base Rate. Each Lender’s obligation to make such payment to the Fronting Bank, and the right of the Fronting Bank to receive the same, shall be absolute and unconditional, shall not be affected by any circumstance whatsoever and without regard to the termination of this Agreement or the Commitments, the existence of a Default or Event of Default or the acceleration of the obligations hereunder and shall be made without any offset, abatement, withholding or reduction whatsoever. Simultaneously with the making of each such payment by a Lender to the Fronting Bank, such Lender shall, automatically and without any further action on the part of the Fronting Bank or such Lender, acquire a participation in an amount equal to such payment (excluding the portion of such payment constituting interest owing to the Fronting Bank) in the related unreimbursed drawing portion of the LC Outstandings and in the interest thereon, and shall have a claim against the Borrower with respect thereto.

(f) On any day on which the Borrower shall have requested, or been deemed to have requested, a Borrowing to reimburse a drawing under a Letter of Credit, the Fronting Bank shall give notice to the Lenders that a Borrowing has been requested or deemed requested in connection with a drawing under a Letter of Credit, in which case an Advance comprised solely of Base Rate Advances (each such borrowing, a “Mandatory Borrowing”) shall be immediately made by all Lenders (without giving effect to any termination of the Commitments pursuant to Section 9.1) pro rata based on each Lender’s Commitment Percentage, and the proceeds thereof shall be paid directly to the Fronting Bank for application to the applicable LC Outstandings. Each Lender hereby irrevocably agrees to make such Base Rate Advances upon any such request or deemed request on account of each such Mandatory Borrowing in the amount and in the manner specified in the preceding sentence and on the same such date notwithstanding (i) the amount of Mandatory Borrowing may not comply with the minimum amount for Borrowings otherwise required hereunder, (ii) whether any conditions specified in Article III are then satisfied, (iii) whether a Default or Event of Default then exists, (iv) failure of any such request or deemed request for a Borrowing to be made by the time otherwise required hereunder, (v) the date of such Mandatory Borrowing, or (vi) any reduction in or any termination of the Commitments. Such funding of Borrowings shall be made on the day notice of such Mandatory Borrowing is received by each Lender from the Fronting Bank if such notice is received at or before 2:00 p.m., otherwise such payment shall be made at or before 12:00 noon on the Business Day next succeeding the day such notice is received. In the event that any Mandatory Borrowing cannot for any reason be made on the date otherwise required above (including, without limitation, as a result of the commencement of a proceeding under any applicable bankruptcy law with respect to the Borrower), then each Lender hereby agrees that it shall forthwith fund (as of the date the Mandatory Borrowing would otherwise have occurred, but adjusted for any payments received from the Borrower on or after such date and prior to such purchase) its Commitment Percentage of the outstanding LC Outstandings; provided, further, that in the event any Lender shall fail to fund its Commitment Percentage on the day the Mandatory Borrowing would otherwise have occurred, then the amount of such Lender’s unfunded Commitment

22

Percentage therein shall bear interest payable to the Fronting Bank upon demand, if paid within two Business Days of such date, at the Federal Funds Rate, and thereafter, at the Base Rate.

(g) The payment obligations of each Lender under subsection (d) and of the Borrower under this Agreement in respect of any payment under any Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances:

(i) any lack of validity or enforceability of any Credit Document or any other agreement or instrument relating thereto or to such Letter of Credit;

(ii) any amendment or waiver of, or any consent to departure from, the terms of any Credit Document or such Letter of Credit;

(iii) the existence of any claim, set-off, defense or other right that the Borrower may have at any time against any beneficiary, or any transferee, of such Letter of Credit (or any persons for whom any such beneficiary or any such transferee may be acting), the Fronting Bank, or any other person, whether in connection with any Credit Document, the transactions contemplated hereby or by such Letter of Credit, or any unrelated transaction;

(iv) any statement or any other document presented under such 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 in good faith by the Fronting Bank under the Letter of Credit issued by the Fronting Bank against presentation of a draft or certificate that does not comply with the terms of such Letter of Credit; or

(vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

(h) The Borrower assumes all risks of the acts and omissions of any beneficiary or transferee of any Letter of Credit. Neither the Fronting Bank, the Lenders nor any of their respective officers, directors, employees, agents or Affiliates shall be liable or responsible for (i) the use that may be made of such Letter of Credit or any acts or omissions of any beneficiary or transferee thereof in connection therewith, (ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged, (iii) payment by the Fronting Bank against presentation of documents that do not comply with the terms of such Letter of Credit, including failure of any documents to bear any reference or adequate reference to such Letter of Credit, or (iv) any other circumstances whatsoever in making or failing to make payment under such Letter of Credit, except that, and notwithstanding subsection (f) and the foregoing clauses (i) through (iii), the Borrower and each Lender shall have the right to bring suit against the Fronting Bank, and the Fronting Bank shall be liable to the Borrower and any Lender, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower or such Lender that the Borrower or such Lender proves were caused by the Fronting Bank’s willful misconduct or gross negligence, including, in the case of the Borrower, the Fronting Bank’s willful failure to make

23

timely payment under such Letter of Credit following the presentation to it by the beneficiary thereof of a draft and accompanying certificate(s) that strictly comply with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, the Fronting Bank may accept sight drafts and accompanying certificates presented under the Letter of Credit issued by the Fronting Bank that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and payment against such documents shall not constitute willful misconduct or gross negligence by the Fronting Bank. Notwithstanding the foregoing, no Lender shall be obligated to indemnify the Borrower for damages caused by the Fronting Bank’s willful misconduct or gross negligence.

(i) The letters of credit listed on Schedule III shall be deemed “Letters of Credit” upon the occurrence of the Effective Date.

Except to the extent otherwise provided herein, all Borrowings, each payment or prepayment of principal of any Advance, each payment of interest on the Advances, each payment of facility fees, LC Fees, each reduction of the Commitments, and each conversion or continuation of any Advance, shall be allocated pro rata among the Lenders in accordance with the respective Commitment Percentages; provided that, if any Lender shall have failed to fund its applicable pro rata share of any Borrowing, then any amount to which such Lender would otherwise be entitled pursuant to this Section 3.6 shall instead be payable to the Agent until the share of such Borrowing not funded by such Lender has been repaid; and provided, further, that in the event any amount paid to any Lender pursuant to this Section 3.6 is rescinded or must otherwise be returned by the Agent, each Lender shall, upon the request of the Agent, repay to the Agent the amount so paid to such Lender, with interest for the period commencing on the date such payment is returned by the Agent until the date the Agent receives such repayment at a rate per annum equal to, during the period to but excluding the date two Business Days after such request, the Federal Funds Rate, and thereafter, the Base Rate plus two percent per annum.

SECTION 3.7. Computations of Interest and Fees.

(a) Except for Base Rate Advances bearing interest determined under clause (i) of the definition of Base Rate, on which interest shall be computed on the basis of a 365 or 366 day year, as the case may be, all computations of interest and fees hereunder shall be made on the basis of the actual number of days elapsed over a year of 360 days.

(b) It is the intent of the Lenders and the Borrower to conform to and contract in strict compliance with applicable usury law from time to time in effect. All agreements between the Lenders and the Borrower are hereby limited by the provisions of this subsection, which shall override and control all such agreements, whether now existing or hereafter arising and whether written or oral. In no way, nor in any event or contingency (including but not limited to prepayment or acceleration of the maturity of any obligation), shall the interest taken, reserved, contracted for, charged, or received under this Agreement or otherwise exceed the maximum nonusurious amount permissible under applicable law. If, from any possible construction of any of the Credit Documents or any other document, interest would otherwise be payable in excess of the maximum nonusurious amount, any such construction shall be subject to the provisions of this subsection and such documents shall be automatically reduced to the maximum nonusurious amount permitted under applicable law, without the necessity of execution of any amendment or new document. If any Lender shall ever receive anything of value that is characterized as interest on the Advances under applicable law and that would, apart from this provision, be in excess of the maximum lawful amount, an amount equal to the amount that would have been excessive interest shall, without penalty, be applied to the reduction of the principal amount owing on the Advances and not to the payment of interest, or refunded to the Borrower or the other payor thereof if and to the extent such amount that would have been excessive exceeds such unpaid principal amount of the Advances. The right to demand payment of the Advances or any other indebtedness evidenced by any of the Credit Documents does not include the right to receive any interest that has not otherwise accrued on the date of such demand, and the Lenders do not intend to charge or receive any unearned interest in the event of such demand. All interest paid or agreed to be paid to the Lenders with respect to the Advances shall, to the

26

extent permitted by applicable law, be amortized, prorated, allocated, and spread throughout the full stated term (including any renewal or extension) of the Advances so that the amount of interest on account of such indebtedness does not exceed the maximum nonusurious amount permitted by applicable law.

SECTION 3.8. Sharing of Payments.

Each Lender agrees that, in the event that any Lender shall obtain payment in respect of any Extension of Credit or any other obligation owing to such Lender under this Agreement through the exercise of a right of set-off, banker’s lien, counterclaim or otherwise (including, but not limited to, pursuant to the Bankruptcy Code) in excess of its pro rata share as provided for in this Agreement, such Lender shall promptly purchase from the other Lenders a participation in such Extension of Credit and other obligations, in such amounts and with such other adjustments from time to time, as shall be equitable in order that all Lenders share such payment in accordance with their respective ratable shares as provided for in this Agreement. Each Lender further agrees that if a payment to a Lender (which is obtained by such Lender through the exercise of a right of set-off, banker’s lien, counterclaim or otherwise) shall be rescinded or must otherwise be restored, each Lender that shall have shared the benefit of such payment shall, by repurchase of a participation theretofore sold, return its share of that benefit to each Lender whose payment shall have been rescinded or otherwise restored. The Borrower agrees that any Lender so purchasing such a participation may, to the fullest extent permitted by law, exercise all rights of payment, including set-off, banker’s lien or counterclaim, with respect to such participation as fully as if such Lender were a holder of such Advance or other obligation in the amount of such participation. Except as otherwise expressly provided in this Agreement, if any Lender shall fail to remit to the Agent or any other Lender an amount payable by such Lender to the Agent or such other Lender pursuant to this Agreement on the date when such amount is due, such payments shall accrue interest thereon, for each day from the date such amount is due until the day such amount is paid to the Agent or such other Lender, at a rate per annum equal to the Federal Funds Rate. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a setoff to which this Section 3.8 applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders under this Section 3.8 to share in the benefits of any recovery on such secured claim.

SECTION 3.9. Additional Interest on Advances.

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

27

SECTION 3.10. Evidence of Debt.

(a) Each Lender shall maintain an account or accounts evidencing each Advance made by such Lender to the Borrower from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement. Each Lender will make reasonable efforts to maintain the accuracy of its account or accounts and to promptly update its account or accounts from time to time, as necessary.

(b) The Agent shall maintain the Register pursuant to Section 11.3(c), and a subaccount for each Lender, in which Register and subaccounts (taken together) shall be recorded (i) the amount, type and Interest Period of each such Advance hereunder, (ii) the amount of any principal or interest due and payable or to become due and payable to each Lender hereunder and (iii) the amount of any sum received by the Agent hereunder from or for the account of the Borrower and each Lender’s share thereof. The Agent will make reasonable efforts to maintain the accuracy of the subaccounts referred to in the preceding sentence and to promptly update such subaccounts from time to time, as necessary.

(c) The entries made in the accounts, Register and subaccounts maintained pursuant to subsection (b) (and, if consistent with the entries of the Agent, subsection (a)) shall be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, however, that the failure of any Lender or the Agent to maintain any such account, such Register or such subaccount, as applicable, or any error therein, shall not in any manner affect the obligation of the Borrower to repay the Advances made by such Lender in accordance with the terms hereof.

(d) Any Lender may request that its Advances be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note, in a form acceptable to the Agent, payable to the order of such Lender. Thereafter, the Advances evidenced by such promissory note and interest thereon shall at all times (including after any assignment pursuant to Section 11.3) be represented by one or more promissory notes payable to the order of the payee named therein or any assignee pursuant to Section 11.3, except to the extent that any such Lender or assignee subsequently returns any such promissory note for cancellation and requests that such Advances once again be evidenced as described in subsections (a) and (b) above.

ARTICLE IV

ADDITIONAL PROVISIONS REGARDING ADVANCES

SECTION 4.1. Eurodollar Borrowing Provisions.

(a) Unavailability. In the event that the Agent shall have determined in good faith (i) that Dollar deposits in the principal amounts requested with respect to a Eurodollar Borrowing are not generally available in the London interbank Eurodollar market or (ii) that reasonable means do not exist for ascertaining the Eurodollar Rate, the Agent shall, as soon as practicable

28

thereafter, give notice of such determination to the Borrower and the Lenders. In the event of any such determination under clause (i) or (ii) above, until the Agent shall have advised the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (A) any request by the Borrower for Eurodollar Borrowings shall be deemed to be a request for Base Rate Borrowings, (B) any request by the Borrower for conversion into or continuation of Eurodollar Borrowings shall be deemed to be a request for conversion into or continuation of Base Rate Borrowings and (C) any Borrowings that were to be converted or continued as Eurodollar Borrowings on the first day of an Interest Period shall be converted to or continued as Base Rate Borrowings.

(b) Change in Legality. Notwithstanding any other provision herein, if any change, after the date hereof, in any law or regulation (including the introduction of any new law or regulation) or in the interpretation thereof by any Governmental Authority charged with the administration or interpretation thereof shall make it unlawful for any Lender to make or maintain any Eurodollar Advance or to give effect to its obligations as contemplated hereby with respect to any Eurodollar Advance, then, by written notice to the Borrower and to the Agent, such Lender may:

(i) declare that Eurodollar Advances, and conversions to or continuations of Eurodollar Advances, will not thereafter be made by such Lender hereunder, whereupon any request by the Borrower for, or for conversion into or continuation of, Eurodollar Borrowings shall, as to such Lender only, be deemed a request for, or for conversion into or continuation of, Base Rate Borrowings, unless such declaration shall be subsequently withdrawn; and

(ii) require that all outstanding Eurodollar Advances made by it be converted to Base Rate Advances in which event all such Eurodollar Advances shall be automatically converted to Base Rate Advances.

In the event any Lender shall exercise its rights under clause (i) or (ii) above, all payments and prepayments of principal that would otherwise have been applied to repay the Eurodollar Advances that would have been made by such Lender or the converted Eurodollar Advances of such Lender shall instead be applied to repay the Base Rate Advances made by such Lenders in lieu of, or resulting from the conversion of, such Eurodollar Advances.

(c) Requirements of Law. If at any time a Lender shall incur increased costs or reductions in the amounts received or receivable hereunder with respect to the making, the commitment to make or the maintaining of any Eurodollar Advance because of (i) any change, after the date hereof, in any applicable law, governmental rule, regulation, guideline or order (or in the interpretation or administration thereof and including the introduction of any new law or governmental rule, regulation, guideline or such order) including, without limitation, the imposition, modification or deemed applicability of any reserves, deposits or similar requirements (such as, for example, but not limited to, a change in official reserve requirements, but, in all events, excluding reserves required under Regulation D to the extent included in the computation of additional interest under Section 3.9) or (ii) other circumstances affecting the London interbank Eurodollar market, then the Borrower shall pay to such Lender promptly upon written demand therefor, such additional amounts (in the form of an increased rate of, or a

29

different method of calculating, interest or otherwise as such Lender may determine in its sole discretion) as may be required to compensate such Lender for such increased costs or reductions in amounts receivable hereunder.

Each determination and calculation made by a Lender under this Section 4.1 shall, absent manifest error, be binding and conclusive on the parties hereto. Any conversions of Eurodollar Advances made pursuant to this Section 4.1 shall subject the Borrower to the payments required by Section 4.3. This Section shall survive termination of this Agreement and the other Credit Documents and payment of the Advances and all other amounts payable hereunder.

SECTION 4.2. Capital Adequacy.

If any Lender has determined that the adoption or effectiveness, after the date hereof, of any applicable law, rule or regulation regarding capital adequacy, or any change therein (after the date hereof), 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 such Lender (or its parent corporation) 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, has or would have the effect of reducing the rate of return on such Lender’s (or parent corporation’s) capital or assets as a consequence of its commitments or obligations hereunder to a level below that which such Lender (or its parent corporation) could have achieved but for such adoption, effectiveness, change or compliance (taking into consideration such Lender’s (or parent corporation’s) policies with respect to capital adequacy), then, upon notice from such Lender, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction. Each determination by any such Lender of amounts owing under this Section 4.2 shall, absent manifest error, be conclusive and binding on the parties hereto. This Section shall survive termination of this Agreement and the other Credit Documents and payment of the Advances and all other amounts payable hereunder.

SECTION 4.3. Compensation.

The Borrower promises to indemnify each Lender and to hold each Lender harmless from any loss or expense that such Lender may sustain or incur as a consequence of (i) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Advances after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (ii) default by the Borrower in making any prepayment of a Eurodollar Advance after the Borrower has given a notice thereof in accordance with the provisions of this Agreement, (iii) the making of a prepayment of Eurodollar Advances on a day that is not the last day of an Interest Period with respect thereto and (iv) the payment, continuation or conversion of a Eurodollar Advance on a day that is not the last day of the Interest Period applicable thereto or the failure to repay a Eurodollar Advance when required by the terms of this Agreement. Such indemnification may include such additional amount or amounts as will compensate such Lender for such loss or expense actually sustained or incurred by such Lender. The agreements in this Section shall survive the termination of this Agreement and the payment of the Advances and all other amounts payable hereunder.

30

SECTION 4.4. Taxes.

(a) Except as provided below in this Section 4.4, all payments made by the Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any court or governmental body, agency or other official, excluding taxes measured by or imposed upon the net income of any Lender or its applicable lending office, or any branch or affiliate thereof, and all franchise taxes, branch taxes, taxes on doing business or taxes on the capital or net worth of any Lender or its applicable lending office, or any branch or affiliate thereof, in each case imposed in lieu of net income taxes (i) by the jurisdiction under the laws of which such Lender, applicable lending office, branch or affiliate is organized or is located, or in which its principal executive office is located, or any nation within which such jurisdiction is located or any political subdivision thereof or (ii) by reason of any connection between the jurisdiction imposing such tax and such Lender, applicable lending office, branch or affiliate other than a connection arising solely from such Lender having executed, delivered or performed its obligations, or received payment under or enforced, this Agreement. If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) are required to be withheld from any amounts payable to an Agent or any Lender hereunder, (A) the amounts so payable to the Agent or such Lender shall be increased to the extent necessary to yield to the Agent or such Lender (after payment of all Non-Excluded Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement and any promissory notes, provided, however, that the Borrower shall be entitled to deduct and withhold any Non-Excluded Taxes and shall not be required to increase any such amounts payable to any Lender that is not organized under the laws of the United States of America or a state thereof if such Lender fails to comply with the requirements of subsection (b) whenever any Non-Excluded Taxes are payable by the Borrower, and (B) as promptly as possible after requested, the Borrower shall send to the Agent for its own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded Taxes when due to the appropriate taxing authority or fails to remit to the Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Agent and any Lender for any incremental Non-Excluded Taxes, interest or penalties that may become payable by the Agent or any Lender as a result of any such failure. The agreements in this Section shall survive the termination of this Agreement and the payment of the Borrowings and all other amounts payable hereunder.

(b) Each Lender that is not incorporated under the laws of the United States of America or a state thereof shall:

(i) (A) on or before the date of any payment by the Borrower under this Agreement to such Lender, deliver to the Borrower and the Agent (x) two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI, or successor applicable form, as the case may be, certifying that it is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes and (y) an Internal Revenue Service Form W-8 or W-9, or successor applicable form, as the case may be, certifying that it is entitled to an exemption from

31

United States backup withholding tax; (B) deliver to the Borrower and the Agent two further copies of any such form or certification on or before the date that any such form or certification expires or becomes obsolete and after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrower; and (C) obtain such extensions of time for filing and complete such forms or certifications as may reasonably be requested by the Borrower or the Agent; or

(ii) in the case of any such Lender that is not a “bank” within the meaning of Section 881(c)(3)(A) of the Internal Revenue Code, (A) represent to the Borrower (for the benefit of the Borrower and the Agent) that it is not a bank within the meaning of Section 88l(c)(3)(A) of the Internal Revenue Code, (B) agree to furnish to the Borrower, on or before the date of any payment by the Borrower, with a copy to the Agent, two accurate and complete original signed copies of Internal Revenue Service Form W-8, or successor applicable form certifying to such Lender’s legal entitlement at the date of such certificate to an exemption from U.S. withholding tax under the provisions of Section 881(c) of the Internal Revenue Code with respect to payments to be made under this Agreement (and to deliver to the Borrower and the Agent two further copies of such form on or before the date it expires or becomes obsolete and after the occurrence of any event requiring a change in the most recently provided form and, if necessary, obtain any extensions of time reasonably requested by the Borrower or the Agent for filing and completing such forms), and (C) agree, to the extent legally entitled to do so, upon reasonable request by the Borrower, to provide to the Borrower (for the benefit of the Borrower and the Agent) such other forms as may be reasonably required in order to establish the legal entitlement of such Lender to an exemption from withholding with respect to payments under this Agreement.

Notwithstanding the above, if any change in treaty, law or regulation has occurred after the date such Person becomes a Lender hereunder which renders all such forms inapplicable or that would prevent such Lender from duly completing and delivering any such form with respect to it and such Lender so advises the Borrower and the Agent, then such Lender shall be exempt from such requirements. Each Person that shall become a Lender or a participant of a Lender pursuant to Section 11.3 shall, upon the effectiveness of the related transfer, be required to provide all of the forms, certifications and statements required pursuant to this subsection (b); provided that in the case of a participant of a Lender, the obligations of such participant of a Lender pursuant to this subsection (b) shall be determined as if the participant of a Lender were a Lender except that such participant of a Lender shall furnish all such required forms, certifications and statements to the Lender from which the related participation shall have been purchased.

SECTION 4.5. Replacement of Lenders.

The Agent and each Lender shall use reasonable efforts to avoid or mitigate any increased cost or suspension of the availability of an interest rate under Sections 4.1 through 4.4 above to the greatest extent practicable (including transferring the Advances to another lending office of Affiliate of a Lender) unless, in the opinion of the Agent or such Lender, such efforts would be likely to have an adverse effect upon it. In the event a Lender makes a request to the Borrower for additional payments in accordance with Section 4.1, 4.2 or 4.4, then, provided that

32

no Default or Event of Default has occurred and is continuing at such time, the Borrower may, at its own expense (such expense to include any transfer fee payable to the Agent under Section 11.3(b) and any expense pursuant to Section 4) and in its sole discretion, require such Lender to transfer and assign in whole (but not in part), without recourse (in accordance with and subject to the terms and conditions of Section 11.3(b)), all of its interests, rights and obligations under this Agreement to an Eligible Assignee, which shall assume such assigned obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) such assignment shall not conflict with any law, rule or regulation or order of any court or other Governmental Authority and (ii) the Borrower or such assignee shall have paid to the assigning Lender in immediately available funds the principal of and interest accrued to the date of such payment on the portion of the Advances hereunder held by such assigning Lender and all other amounts owed to such assigning Lender hereunder, including amounts owed pursuant to Sections 4.1 through 4.4.

Upon the occurrence of an Event of Default, and at any time thereafter unless and until such Event of Default has been waived by the Required Lenders (or the Lenders as may be required hereunder) the Agent may, and shall, upon the request and direction of the Required Lenders, by written notice to the Borrower take any of the following actions without prejudice to the rights of the Agent or any Lender to enforce its claims against the Borrower, except as otherwise specifically provided for herein:

(a) Termination of the Commitments. Declare the Commitments terminated whereupon the Commitments shall be immediately terminated.

(b) Acceleration of Advances. Declare the unpaid amount of all Advances and all other amounts payable by the Borrower hereunder to be due whereupon the same shall be immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower.

(c) Enforcement of Rights. Enforce any and all rights and interests created and existing under the Credit Documents, including, without limitation, all rights of set-off.

(d) Cash Collateralization of LC Outstandings. Notwithstanding anything to the contrary contained herein, no notice given or declaration made by the Agent pursuant to this Article IX shall affect (i) the obligation of the Fronting Bank to make any payment under any Letter of Credit in accordance with the terms of such Letter of Credit or (ii) the obligations of each Lender in respect of each such Letter of Credit; provided, however, that if an Event of Default has occurred and is continuing, the Agent shall at the request, or may with the consent, of the Required Lenders, upon notice to the Borrower, require the Borrower to deposit with the Agent an amount in the cash collateral account (the “Cash Collateral Account”) described below

47

equal to the LC Outstandings on such date. Such Cash Collateral Account shall at all times be free and clear of all rights or claims of third parties. The Cash Collateral Account shall be maintained with the Agent in the name of, and under the sole dominion and control of, the Agent, and amounts deposited in the Cash Collateral Account shall bear interest at a rate equal to the rate generally offered by the Agent for deposits equal to the amount deposited by the Borrower in the Cash Collateral Account, for a term to be determined by the Agent, in its sole discretion. The Borrower hereby grants to the Agent for the benefit of the Fronting Bank and the Lenders a Lien in and hereby assigns to the Agent for the benefit of the Fronting Bank and the Lenders all of its right, title and interest in, the Cash Collateral Account and all funds from time to time on deposit therein to secure its reimbursement obligations in respect of Letters of Credit. If any drawings then outstanding or thereafter made are not reimbursed in full immediately upon demand or, in the case of subsequent drawings, upon being made, then, in any such event, the Agent may apply the amounts then on deposit in the Cash Collateral Account, toward the payment in full of any of the obligations as and when such obligations shall become due and payable. Upon payment in full, after the termination of the Letters of Credit, of all such obligations, the Agent will repay and reassign to the Borrower any cash then in the Cash Collateral Account and the Lien of the Agent on the Cash Collateral Account and the funds therein shall automatically terminate. In addition, at any time the Borrower is required under Section 2.8(c) or 3.2(b) to cash collateralize any of the LC Outstandings, the Borrower shall deposit such amount in the Cash Collateral Account. If, at any time no Event of Default has occurred and is continuing and the cash on deposit in the Cash Collateral Account shall exceed the LC Outstandings, then the Agent will repay and reassign to the Borrower cash in an amount equal to such excess, and the Lien of the Agent on such cash shall automatically terminate.

(e) Notwithstanding the foregoing, if an Event of Default specified in Section 9.1(e) shall occur, then the Commitments shall automatically terminate and all Advances, all accrued interest in respect thereof, all accrued and unpaid fees and other indebtedness or obligations owing to the Lenders and the Agent hereunder shall immediately become due and payable without the giving of any notice or other action by the Agent or the Lenders.

(f) Notwithstanding the fact that enforcement powers reside primarily with the Agent, each Lender has, to the extent permitted by law, a separate right of payment and shall be considered a separate “creditor” holding a separate “claim” within the meaning of Section 101(5) of the Bankruptcy Code or any other insolvency statute.

SECTION 9.3. Allocation of Payments After Event of Default.

Notwithstanding any other provisions of this Agreement, after the occurrence of an Event of Default, all amounts collected or received by the Agent or any Lender on account of amounts outstanding under any of the Credit Documents shall be paid over or delivered as follows:

FIRST, to the payment of all reasonable out-of-pocket costs and expenses (including without limitation reasonable attorneys’ fees) of the Agent or any of the Lenders in connection with enforcing the rights of the Lenders under the Credit Documents, pro rata as set forth below;

48

SECOND, to payment of any fees owed to the Agent or any Lender, pro rata as set forth below;

In carrying out the foregoing, (i) amounts received shall be applied in the numerical order provided until exhausted prior to application to the next succeeding category; and (ii) each of the Lenders shall receive an amount equal to its pro rata share (based on the proportion that the then Outstanding Credits held by such Lender bears to the aggregate then outstanding Advances of amounts available to be applied.

The Agent shall not be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it with reasonable care.

SECTION 10.3. Exculpatory Provisions.

Neither the Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates shall be liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection herewith or in connection with any of the other Credit Documents (except for its or such Person’s own gross negligence or willful misconduct), or responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by the Borrower contained herein or in any of the other Credit Documents or in any certificate, report, statement or other document referred to or provided for in, or received by the Agent under or in connection herewith or in connection with the other Credit Documents, or enforceability or sufficiency therefor of any of the other Credit Documents, or for any failure of the Borrower to perform its obligations hereunder or thereunder. The Agent shall not be responsible to any Lender for the effectiveness, genuineness, validity, enforceability, collectibility or sufficiency of this Agreement, or any of the other Credit Documents or for any representations, warranties, recitals or statements made herein or therein or made by the Borrower in any written or oral statement or in any financial or other statements, instruments, reports, certificates or any other documents in connection herewith or therewith furnished or made by the Agent to the Lenders or the Fronting Bank or by or on behalf of the Borrower to the Agent or any Lender or the Fronting Bank or be required to ascertain or inquire as to the performance or observance of any of the terms, conditions, provisions, covenants or agreements contained herein or therein or as to the use of the proceeds of the Advances or of the existence or possible existence of any Default or Event of Default or to inspect the properties, books or records of the Borrower. The Agent is not a trustee for the Lenders or the Fronting Bank and owes no fiduciary duty to the Lenders or the Fronting Bank.

SECTION 10.4. Reliance on Communications.

The Agent shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document or conversation believed by it in good faith to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Borrower, independent accountants and other experts selected by the Agent with reasonable care). The Agent may deem and treat the Lenders as the owner of its interests hereunder for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Agent in accordance with Section 11.3(b). The Agent shall be fully justified in failing or refusing to take any action under this Agreement or under any of the other Credit Documents unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or

50

continuing to take any such action. The Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder or under any of the other Credit Documents in accordance with a request of the Required Lenders (or to the extent specifically provided in Section 11.6, all the Lenders) and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders (including their successors and assigns).

SECTION 10.5. Notice of Default.

The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the Agent has received notice from a Lender or the Borrower referring to the Credit Document, describing such Default or Event of Default and stating that such notice is a “notice of default”. In the event that the Agent receives such a notice, the Agent shall give prompt notice thereof to the Lenders. The Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders.

SECTION 10.6. Non-Reliance on Agent and Other Lenders.

Each Lender and the Fronting Bank expressly acknowledges that neither the Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates has made any representations or warranties to it and that no act by the Agent or any affiliate thereof hereinafter taken, including any review of the affairs of the Borrower, shall be deemed to constitute any representation or warranty by the Agent to any Lender or the Fronting Bank. Each Lender and the Fronting Bank represents to the Agent that it has, independently and without reliance upon the Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, assets, operations, property, financial and other conditions, prospects and creditworthiness of the Borrower and made its own decision to make its Extensions of Credit hereunder and enter into this Agreement. Each Lender and the Fronting Bank also represents that it will, independently and without reliance upon the Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement, and to make such investigation as it deems necessary to inform itself as to the business, assets, operations, property, financial and other conditions, prospects and creditworthiness of the Borrower. Except for notices, reports and other documents expressly required to be furnished to the Lenders and the Fronting Bank by the Agent hereunder, the Agent shall not have any duty or responsibility to provide any Lender or the Fronting Bank with any credit or other information concerning the business, operations, assets, property, financial or other conditions, prospects or creditworthiness of the Borrower that may come into the possession of the Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates.

SECTION 10.7. Indemnification.

Each Lender agrees to indemnify the Agent in its capacity as such (to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so), ratably according to its Commitment Percentage, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or

51

disbursements of any kind whatsoever that may at any time (including without limitation at any time following the payment in full of the Advances and the other obligations of the Borrower hereunder) be imposed on, incurred by or asserted against the Agent in its capacity as such in any way relating to or arising out of this Agreement or the other Credit Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the gross negligence or willful misconduct of the Agent. If any indemnity furnished to the Agent for any purpose shall, in the opinion of the Agent, be insufficient or become impaired, the Agent may call for additional indemnity and cease, or not commence, to do the acts indemnified against until such additional indemnity is furnished. The agreements in this Section 10.7 shall survive the payment of the Advances and all other amounts payable hereunder.

SECTION 10.8. Agent in Its Individual Capacity.

The Agent in its individual capacity and its Affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Borrower as though the Agent were not Agent hereunder. With respect to the Advances made and all obligations of the Borrower owing to the Agent, the Agent in its individual capacity shall have the same rights and powers under this Agreement as any Lender and may exercise the same as though they were not Agent, and the terms “Lender” and “Lenders” shall include U.S. Bank in its individual capacity.

SECTION 10.9. Successor Agent.

The Agent may, and at the request of the Required Lenders shall, resign as the Agent upon 30 days notice to the Lenders and the Fronting Bank. If the Agent resigns under this Agreement, the Required Lenders and the Fronting Bank shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall be approved by the Borrower so long as no Event of Default has occurred and is continuing. If no successor agent is appointed prior to the effective date of the resignation of the Agent, the Agent may appoint, after consulting with the Lenders and the Borrower, a successor agent from among the Lenders. Upon the acceptance of its appointment as successor agent hereunder, such successor agent shall succeed to all the rights, powers and duties of the retiring Agent, and the term “Agent” shall mean such successor agent and the retiring Agent’s appointment, powers and duties as Agent shall be terminated. After any retiring Agent’s resignation hereunder as Agent, the provisions of this Section 10 and Section 11.5 shall inure to its benefit as to any actions taken or omitted to be taken, by it while it was the Agent under this Agreement. If no successor agent has accepted appointment as the Agent by the date that is 30 days following a retiring Agent’s notice of resignation, the retiring Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above.

SECTION 11.2. Right of Set-Off.

In addition to any rights now or hereafter granted under applicable law or otherwise, and not by way of limitation of any such rights, upon the occurrence of an Event of Default and the commencement of remedies described in Section 9.2, each Lender is authorized at any time and from time to time, without presentment, demand, protest or other notice of any kind (all of which rights being hereby expressly waived), to set off and to appropriate and apply any and all deposits (general or special) and any other indebtedness at any time held or owing by such Lender (including, without limitation branches, agencies or Affiliates of such Lender wherever located) to or for the credit or the account of the Borrower against obligations and liabilities of the Borrower to the Lenders hereunder or under the other Credit Documents or otherwise, irrespective of whether the Agent or the Lenders shall have made any demand hereunder and although such obligations, liabilities or claims, or any of them, may be contingent or unmatured, and any such set-off shall be deemed to have been made immediately upon the occurrence of an Event of Default even though such charge is made or entered on the books of such Lender subsequent thereto. The Borrower hereby agrees that any Person purchasing a participation in the Advances and the Commitments hereunder pursuant to Section 11.3(c) may exercise all rights of set-off with respect to its participation interest as fully as if such Person were a Lender hereunder.

SECTION 11.3. Benefit of Agreement.

(a) Generally. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto; provided the Borrower may not assign and transfer any of its interests without the prior written consent of the Lenders and the Fronting Bank; and provided, further, that the rights of each Lender to transfer, assign or grant participations in its rights and/or obligations hereunder shall be limited as set forth below in this Section 11.3.

(b) Assignments. Each Lender may assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Advances and its Commitment); provided, however, that:

(i) each such assignment shall be to an Eligible Assignee;

53

(ii) except in the case of an assignment to another Lender, an Approved Fund of any Lender or an Affiliate of any Lender, or an assignment of all of a Lender’s rights and obligations under this Agreement, any such partial assignment shall be in an amount at least equal to $5,000,000 (or, if less, the remaining amount of the Commitment being assigned by such Lender) and an integral multiple of $1,000,000 in excess thereof;

(iii) each such assignment by a Lender shall be of a constant and not varying, percentage of all of its rights and obligations under this Agreement; and

(iv) the parties to such assignment shall execute and deliver to the Agent for its acceptance an Assignment Agreement together with a processing fee (other than in connection with any assignment to a Lender, an Approved Fund of any Lender or an Affiliate of such Lender) from the assignor of $3,500.

Upon execution, delivery, and acceptance of such Assignment Agreement, the assignee thereunder shall be a party hereto and, to the extent of such assignment, have the obligations, rights, and benefits of a Lender hereunder and the assigning Lender shall, to the extent of such assignment, relinquish its rights and be released from its obligations under this Agreement. Upon the consummation of any assignment pursuant to this subsection (b), the assignor, the Agent and the Borrower shall make appropriate arrangements so that, if required, new promissory notes are issued to the assignor and the assignee. If the assignee is not incorporated under the laws of the United States of America or a state thereof, it shall deliver to the Borrower and the Agent certification as to exemption from deduction or withholding of taxes in accordance with Section 4.4.

By executing and delivering an Assignment Agreement in accordance with this subsection (b), the assigning Lender thereunder and the assignee thereunder shall be deemed to confirm to and agree with each other and the other parties hereto as follows: (A) such assigning Lender represents and warrants that it is legally authorized to enter into such Assignment Agreement and it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim created by such assigning Lender and the assignee warrants that it is an Eligible Assignee; (B) except as set forth in clause (A) above, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto, or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto or the financial condition of the Borrower or the performance or observance by the Borrower of any of its obligations under this Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto; (C) such assignee represents and warrants that it is legally authorized to enter into such Assignment Agreement; (D) such assignee confirms that it has received a copy of this Agreement, the other Credit Documents and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment Agreement; (E) such assignee will independently and without reliance upon the Agent, such assigning Lender or any other Lender, 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

54

action under this Agreement and the other Credit Documents; (F) such assignee appoints and authorizes the Agent to take such action on its behalf and to exercise such powers under this Agreement or any other Credit Document as are delegated to the Agent by the terms hereof or thereof, together with such powers as are reasonably incidental thereto; and (G) such assignee agrees that it will perform in accordance with their terms all the obligations that by the terms of this Agreement and the other Credit Documents are required to be performed by it as a Lender.

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

(d) Acceptance. Upon its receipt of an Assignment Agreement executed by the parties thereto, together with and payment of the processing fee, the Agent shall, if such Assignment Agreement has been completed and is in substantially the form of Exhibit D hereto, (i) accept such Assignment Agreement, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the parties thereto.

(e) Participations. Each Lender may sell participations to one or more Persons in all or a portion of its rights, obligations or rights and obligations under the Credit Documents (including all or a portion of its Commitment and its Advances); provided, however, that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the participant shall be entitled to the benefit of the yield protection provisions contained in Sections 4.1 through 4.4, inclusive, and the right of set-off contained in Section 11.2, and (iv) the Borrower shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement, and such Lender shall retain the sole right to enforce the obligations of the Borrower relating to its Advances and to approve any amendment, modification, or waiver of any provision of this Agreement (other than amendments, modifications, or waivers decreasing the amount of principal of or the rate at which interest is payable on such Advances, extending any principal payment date or date fixed for the payment of interest on such Advances, or extending its Commitment).

(f) Nonrestricted Assignments. Notwithstanding any other provision set forth in this Agreement:

(i) any Lender may at any time, without the consent of the Borrower or the Agent, assign all or any portion of its rights under the Credit Documents to any Federal Reserve Bank as security. No such assignment shall release the assigning Lender from its obligations hereunder;

(ii) any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”) of such Granting Lender identified as such in writing from time to

55

time by the Granting Lender to the Agent and the Borrower, the option to provide to the Borrower all or any part of any Extension of Credit that such Granting Lender would otherwise be obligated to make to such Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any such SPC to make any Extension of Credit, (ii) if such SPC elects not to exercise such option or otherwise fails to provide all or any part of such Extension of Credit, the Granting Lender shall be obligated to make such Extension of Credit pursuant to the terms hereof and (iii) no SPC or Granting Lender shall be entitled to receive any greater amount pursuant to Section 4.1(c) or 4.4 than the Granting Lender would have been entitled to receive had the Granting Lender not otherwise granted such SPC the option to provide any Extension of Credit to the Borrower. The making of an Extension of Credit by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Extension of Credit were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender would otherwise be liable so long as, and to the extent that, the related Granting Lender provides such indemnity or makes such payment. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against or join any other person in instituting against such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. Notwithstanding the foregoing, the Granting Lender unconditionally agrees to indemnify the Borrower, the Agent, the Fronting Bank and each Lender against all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be incurred by or asserted against the Borrower, the Agent, the Fronting Bank or such Lender, as the case may be, in any way relating to or arising as a consequence of any such forbearance or delay in the initiation of any such proceeding against its SPC. Each party hereto hereby acknowledges and agrees that no SPC shall have the rights of a Lender hereunder, such rights being retained by the applicable Granting Lender. Accordingly, and without limiting the foregoing, each party hereby further acknowledges and agrees that no SPC shall have any voting rights hereunder and that the voting rights attributable to any Extension of Credit made by an SPC shall be exercised only by the relevant Granting Lender and that each Granting Lender shall serve as the administrative agent and attorney-in-fact for its SPC and shall on behalf of its SPC receive any and all payments made for the benefit of such SPC and take all actions hereunder to the extent, if any, such SPC shall have any rights hereunder. In addition, notwithstanding anything to the contrary contained in this Agreement, any SPC may (i) with notice to, but without the prior written consent of any other party hereto, assign all or a portion of its interest in any Extension of Credit to the Granting Lender and (ii) disclose on a confidential basis any information relating to its Extensions of Credit to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This Section may not be amended without the prior written consent of each Granting Lender, all or any part of whose Extension of Credit is being funded by an SPC at the time of such amendment; and

56

(iii) any Lender at any time may assign all or any portion of its rights and obligations under this Agreement to any Affiliate or Approved Fund of such Lender, provided such assignment does not result in the incurrence of any increased payment obligations by any Borrower under Section 4.2 or 4.4. Upon execution, delivery, and acceptance of such Assignment Agreement, the assignee thereunder shall be a party hereto and, to the extent of such assignment, have the obligations, rights, and benefits of a Lender hereunder and the assigning Lender shall, to the extent of such assignment, relinquish its rights and be released from its obligations under this Agreement. If the assignee is not incorporated under the laws of the United States of America or a state thereof, it shall deliver to the Borrower and the Agent certification as to exemption from deduction or withholding of taxes in accordance with Section 4.4.

(g) Information. Any Lender may furnish any information concerning the Borrower in the possession of such Lender from time to time to assignees and participants (including prospective assignees and participants) or to any party that such Lender has engaged or proposes to engage in any swap, securitization or derivative transaction involving any of such Lender’s rights or obligations hereunder.

SECTION 11.4. No Waiver; Remedies Cumulative.

No failure or delay on the part of the Agent, the Fronting Bank or any Lender in exercising any right, power or privilege hereunder or under any other Credit Document and no course of dealing between the Borrower and the Agent, the Fronting Bank or any Lender shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege hereunder or under any other Credit Document preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. The rights and remedies provided herein are cumulative and not exclusive of any rights or remedies that the Agent, the Fronting Bank or any Lender would otherwise have. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Agent, the Fronting Bank or the Lenders to any other or further action in any circumstances without notice or demand.

SECTION 11.5. Payment of Expenses, etc.

The Borrower agrees to: (i) pay all reasonable out-of-pocket costs and expenses of the Agent in connection with (A) the negotiation, preparation, execution and delivery and administration of this Agreement and the other Credit Documents and the documents and instruments referred to therein (including, without limitation, legal fees of the Agent) and (B) any amendment, waiver or consent relating hereto and thereto including, but not limited to, any such amendments, waivers or consents resulting from or related to any work-out, renegotiation or restructure relating to the performance by the Borrower under this Agreement; (ii) pay all reasonable out-of-pocket costs and expenses of the Agent, the Fronting Bank and the Lenders in connection with (A) enforcement of the Credit Documents and the documents and instruments referred to therein (including, without limitation, in connection with any such enforcement, the reasonable fees and disbursements of counsel for the Agent, the Fronting Bank and each of the Lenders) and (B) any bankruptcy or insolvency proceeding of the Borrower; and

57

(iii) indemnify the Agent, the Fronting Bank and each Lender, its affiliates, officers, directors, employees, advisors and agents from and hold each of them harmless against any and all losses, liabilities, claims, damages or expenses incurred by any of them as a result of, or arising out of, or in any way related to, or by reason of, any investigation, litigation or other proceeding (whether or not the Agent or any Lender is a party thereto) related to the entering into and/or performance of any Credit Document or the use of proceeds of any Extension of Credit hereunder or the consummation of any other transactions contemplated in any Credit Document, including, without limitation, the reasonable fees and disbursements of counsel incurred in connection with any such investigation, litigation or other proceeding (but excluding any such losses, liabilities, claims, damages or expenses to the extent incurred by reason of gross negligence or willful misconduct on the part of the Person to be indemnified). Such expenses shall be reimbursed by the Borrower upon presentation of a statement of account, which statement shall be conclusive absent manifest error.

SECTION 11.6. Amendments, Waivers and Consents.

Neither this Agreement, nor any other Credit Document nor any of the terms hereof or thereof may be amended, changed, waived, discharged or terminated unless such amendment, change, waiver, discharge or termination is in writing and signed by the Required Lenders and the Borrower; provided that no amendment, waiver or consent shall, unless in writing and signed by the Fronting Bank in addition to the Required Lenders and the Borrower, affect the rights or duties of the Fronting Bank under this Agreement or any other Credit Document, and provided further, that no such amendment, change, waiver, discharge or termination shall without the consent of each Lender affected thereby:

(a) extend the Maturity Date, or postpone or extend the time for any payment or prepayment of principal, except as provided in Section 2.7;

(b) reduce the rate or extend the time of payment of interest (other than as a result of waiving the applicability of any post-default increase in interest rates) thereon or fees or other amounts payable hereunder;

(c) reduce or waive the principal amount of any Advance;

(d) increase or extend the Commitment (it being understood and agreed that a waiver of any Default or Event of Default shall not constitute a change in the terms of any Commitment of any Lender);

(e) release the Borrower from its obligations under the Credit Documents;

(f) amend, modify or waive any provision of this Section 11.6 or Section 3.6, 3.8, 4.1, 4.2, 4.3, 4.4, 9.1(a), 11.2, 11.3 or 11.5;

(g) reduce any percentage specified in, or otherwise modify, the definition of Required Lenders; or

(h) consent to the assignment or transfer by the Borrower of any of its rights and obligations under (or in respect of) the Credit Documents.

58

Notwithstanding the foregoing, this Agreement may be amended and restated without the consent of any Lender or the Agent if, upon giving effect to such amendment and restatement, such Lender or the Agent, as the case may be, shall no longer be a party to this Agreement (as so amended and restated) or have any Commitment or other obligation hereunder and shall have been paid in full all amounts payable hereunder to such Lender or the Agent, as the case may be. No provision of Section 10 may be amended or modified without the consent of the Agent.

Notwithstanding the fact that the consent of all the Lenders is required in certain circumstances as set forth above, each Lender is entitled to vote as such Lender sees fit on any reorganization plan that affects the Extensions of Credit, and each Lender acknowledges that the provisions of Section 1126(c) of the Bankruptcy Code supersedes the unanimous consent provisions set forth herein.

SECTION 11.7. Counterparts/Telecopy.

This Agreement may be executed in any number of counterparts, each of which where so executed and delivered shall be an original, but all of which shall constitute one and the same instrument. Delivery of executed counterparts by telecopy shall be as effective as an original and shall constitute a representation that an original will be delivered.

SECTION 11.8. Headings.

The headings of the Sections and subsections hereof are provided for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement.

SECTION 11.9. Defaulting Lender.

Each Lender understands and agrees that if such Lender is a Defaulting Lender then it shall not be entitled to vote on any matter requiring the consent of the Required Lenders or to object to any matter requiring the consent of all the Lenders; provided, however, that all other benefits and obligations under the Credit Documents shall apply to such Defaulting Lender.

SECTION 11.10. Confidentiality.

Each of the Agent, each Lender and the Fronting Bank agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed by such Person (i) to its Affiliates and to its and its Affiliates’ respective partners, directors, officers, employees, agents, advisors and other representatives (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (ii) to the extent requested by any regulatory authority purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (iii) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (iv) to any other party hereto, (v) in connection with the exercise of any remedies hereunder or under any other Credit Document or any action or proceeding relating to this Agreement or any other Credit Document or the enforcement of rights hereunder or thereunder, (vi) subject to an agreement containing provisions substantially the same as those of this Section, to (A) any assignee of or participant, or any prospective assignee of or participant in, any of its rights or

59

obligations under this Agreement or (B) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower and its obligations, (vii) with the consent of the Borrower or (viii) to the extent such Information (A) becomes publicly available other than as a result of a breach of this Section or (B) becomes available to the Agent, any Lender, the Fronting Bank or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrower. Notwithstanding anything in this Agreement to the contrary, the Borrower, the Agent, the Fronting Bank and each Lender (and each officer, director, employee, agent and advisor of each such Person) shall not be limited from disclosing the US tax treatment or the US tax structure of the transactions contemplated hereby. For purposes of this Section, “Information” means all information received from the Borrower or any of its Subsidiaries relating to the Borrower or any of its Subsidiaries or any of their respective businesses, other than any such information that is available to the Agent, any Lender or the Fronting Bank on a nonconfidential basis prior to disclosure by the Borrower or any of its Subsidiaries, provided that, in the case of information received from the Borrower or any of its Subsidiaries after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

SECTION 11.11. Survival of Indemnification and Representations and Warranties.

All indemnities set forth herein and all representations and warranties made herein shall survive the execution and delivery of this Agreement, the making of Extensions of Credit and the repayment of the Borrowings and other obligations and the termination of the Commitments hereunder.

SECTION 11.12. Governing Law; Venue.

(a) THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

THE COMMITMENTS AND THE EXTENSIONS OF CREDIT

SECTION 2.1. The Commitments.

Subject to the terms and conditions set forth herein, each Lender severally agrees to make Advances to the Borrower in Dollars, at any time and from time to time prior to the Maturity Date, in an amount not to exceed at any time such Lender’s Commitment, the Fronting Bank agrees to issue Letters of Credit for the account of the Borrower at any time and from time to time until the fifth Business Day preceding the Maturity Date in an aggregate stated amount at any time outstanding not to exceed the LC Commitment Amount, and each Lender agrees to purchase participations in such Letters of Credit as more fully set forth in Section 2.8; provided, however, that (i) the aggregate amount of Outstanding Credits shall not exceed the aggregate Commitments and (ii) with respect to each individual Lender, such Lender’s pro rata share of Outstanding Credits shall not exceed such Lender’s Commitment Percentage of the aggregate Commitments. Unless and until the Borrower has obtained a Long-Term PSCW Approval (and provided the Agent with a copy thereof), amounts borrowed and repaid hereunder may not be reborrowed; thereafter, subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow Advances.

SECTION 2.2. Method of Borrowing.

By no later than 11:00 a.m. (i) on the date of the requested Borrowing that will comprise Base Rate Advances or (ii) three Business Days prior to the date of the requested Borrowing that will comprise Eurodollar Advances, the Borrower shall submit to the Agent a written Notice of Borrowing in the form of Exhibit A setting forth (A) the amount requested, (B) whether such Advances shall accrue interest at the Base Rate or the Eurodollar Rate, (C) with respect to Borrowings that will comprise Eurodollar Advances, the Interest Period applicable thereto, and (D) certification that the Borrower has complied in all respects with Section 5.2.

16

SECTION 2.3. Funding of Borrowings.

(a) Upon receipt of a Notice of Borrowing, the Agent shall promptly inform the Lenders as to the terms thereof. Each such Lender shall make its Commitment Percentage of the requested Borrowing available to the Agent by 1:00 p.m. on the date specified in the Notice of Borrowing by deposit, in Dollars, of immediately available funds at the principal offices of the Agent in New York, New York or at such other address as the Agent may designate in writing. The amount of the requested Borrowing will then be made available to the Borrower by the Agent by crediting the account of the Borrower on the books of such office of the Agent, to the extent the amount of such Borrowing is made available to the Agent.

(b) No Lender shall be responsible for the failure or delay by any other Lender in its obligation to make Advances hereunder; provided, however, that the failure of any Lender to fulfill its obligations hereunder shall not relieve any other Lender of its obligations hereunder. Unless the Agent shall have been notified by any Lender prior to the date of any such Borrowing (in the case of a Eurodollar Borrowing) or the time of any such Borrowing (in the case of a Base Rate Borrowing) that such Lender does not intend to make available to the Agent its portion of the Borrowing to be made on such date, the Agent may assume that such Lender has made such amount available to the Agent on the date of such Borrowing, and the Agent in reliance upon such assumption, may (in its sole discretion but without any obligation to do so) make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the Agent, the Agent shall be able to recover such corresponding amount from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Agent’s demand therefor, the Agent will promptly notify the Borrower, and the Borrower shall immediately pay such corresponding amount to the Agent. The Agent shall also be entitled to recover from the Lender or the Borrower, as the case may be, interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the Agent to the Borrower to the date such corresponding amount is recovered by the Agent at a per annum rate equal to, (i) if from the Borrower, the applicable rate for such Advance pursuant to the Notice of Borrowing and (ii) if from a Lender, the Federal Funds Rate.

SECTION 2.4. Continuations and Conversions.

The Borrower shall have the option, on any Business Day, to continue existing Eurodollar Advances for a subsequent Interest Period, to convert Base Rate Advances into Eurodollar Advances or to convert Eurodollar Advances into Base Rate Advances; provided, however, that (i) each such continuation or conversion must be requested by the Borrower pursuant to a written Notice of Continuation/Conversion, in the form of Exhibit B, in compliance with the terms set forth below, (ii) except as provided in Section 4.1, Eurodollar Advances may be continued or converted into Base Rate Advances only on the last day of the Interest Period applicable hereto, (iii) Eurodollar Advances may not be continued nor may Base Rate Advances be converted into Eurodollar Advances during the existence and continuation of a Default or Event of Default and (iv) any request to extend a Eurodollar Advance that fails to comply with the terms hereof or any failure to request an extension of a Eurodollar Advance that fails to

17

comply with the terms hereof or any failure to request an extension of a Eurodollar Advance at the end of an Interest Period shall constitute a conversion to a Base Rate Advance on the last day of the applicable Interest Period. Each continuation or conversion must be requested by the Borrower no later than 11:00 a.m. (A) on the date for a requested conversion of a Eurodollar Advance to a Base Rate Advance or (B) three Business Days prior to the date for a requested continuation of a Eurodollar Advance or conversion of a Base Rate Advance to a Eurodollar Advance, in each case pursuant to a written Notice of Continuation/Conversion submitted to the Agent, which shall set forth (1) whether the Borrower wishes to continue or convert such Advances and (2) if the request is to continue a Eurodollar Advance or convert a Base Rate Advance to a Eurodollar Advance, the Interest Period applicable thereto.

SECTION 2.5. Minimum Amounts.

Each request for a Borrowing or a conversion or continuation hereunder shall be subject to the following requirements: (i) each Borrowing consisting of Eurodollar Advances shall be in a minimum of $5,000,000 (and in integral multiples of $1,000,000 in excess thereof); (ii) each Borrowing consisting of Base Rate Advances shall be in a minimum amount of the lesser of $500,000 (and in integral multiples of $500,000 in excess thereof) and the remaining amount available to be borrowed; and (iii) no more than ten Eurodollar Borrowings shall be outstanding hereunder at any one time. For the purposes of this Section, all Eurodollar Borrowings with the same Interest Periods that begin and end on the same date shall be considered as one Eurodollar Borrowing, but Eurodollar Borrowings with different Interest Periods, even if they begin on the same date, shall be considered separate Eurodollar Borrowings.

SECTION 2.6. Reduction of the Commitments.

(a) Optional Reduction of Commitments. Upon at least five Business Days’ notice, the Borrower shall have the right to permanently terminate or reduce the aggregate unused amount of the Commitments at any time or from time to time; provided that each partial reduction shall be in an aggregate amount at least equal to $5,000,000 and in integral multiples of $1,000,000 above such amount and no reduction shall be made that would reduce the Commitments to an amount less than the then Outstanding Credits. Any reduction in (or termination of) the Commitments shall be permanent and may not be reinstated.

(b) Mandatory Reduction of Commitments. For so long as the Borrower has not obtained a Long-Term PSCW Approval, upon the repayment or prepayment of any Borrowing pursuant to Section 3.2 or Section 3.3, the Commitments shall automatically and permanently be reduced by an amount equal to the aggregate principal amount of the Borrowing so repaid or prepaid.

Each Lender shall notify the Agent by Requisite Notice by the date specified by the Agent (which date shall be a Business Day and shall not be less than 15 Business Days prior to, nor more than 30 days prior to, the then Maturity Date) that either (A) such Lender declines to consent to extending the Maturity Date or (B) such Lender consents to extending the Maturity Date. Any Lender not responding within the above time period shall be deemed not to have consented to extending the Maturity Date. The Agent shall, after receiving the notifications from all of the Lenders or the expiration of such period, whichever is earlier, notify the Borrower and the Lenders of the results thereof. The Borrower may request no more than two extensions pursuant to this Section.

(b) If any Lender declines, or is deemed to have declined, to consent to such request for extension (a “Declining Lender”), provided that (i) no Default or Event of Default has occurred and is continuing at such time and (ii) the Required Lenders are non-Declining Lenders, the Borrower may, at its own expense (such expense to include any transfer fee payable to the Agent under Section 11.3(b) and any expense pursuant to Section 4.3) and in its sole discretion, require such Declining Lender to transfer and assign in whole (but not in part) without recourse (in accordance with and subject to the terms and conditions of Section 11.3(b)) all of its interests, rights and obligations under this Agreement to an Eligible Assignee, which shall assume such assigned obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (A) such assignment shall not conflict with any law, rule or regulation or order of any court or other Governmental Authority and (B) the assigning Declining Lender shall have received in immediately available funds the principal of and interest accrued to the date of such payment on the portion of the Advances hereunder held by such assigning Declining Lender and all other amounts owed to such assigning Declining Lender hereunder, including amounts owed pursuant to Sections 4.1 through 4.4.

(c) If the conditions set forth in subsection (b) above have been satisfied, the Maturity Date shall be extended (solely with respect to the non-Declining Lenders) to the date that is one year after the then-effective Maturity Date, effective as of the date to be determined by the Agent and the Borrower (the “Maturity Extension Decision Date”), and the Agent shall promptly notify the Lenders thereof. On or prior to the Maturity Extension Decision Date, the Borrower shall deliver to the Agent, in form and substance satisfactory to the Agent and the Lenders (i) the resolutions of the Board of Directors of the Borrower authorizing such extension, certified as in effect as of the Maturity Extension Decision Date and the related incumbency certificate of the Borrower, (ii) new or amended promissory notes, if requested by any new or affected Lender, evidencing the new or revised Commitment of such Lender, (iii) a certificate of the Borrower stating that on and as of such Maturity Extension Decision Date, and after giving effect to the extension to be effective on such date, (A) the representations and warranties set forth in Article VI are true and correct and (B) no Default or Event of Default is continuing. The Agent shall distribute an amended Schedule I to this Agreement (which shall thereafter be incorporated into this Agreement), to reflect any changes in Lenders, the Commitments and each Lender’s Commitment Percentage.

Each Request for Issuance shall specify (i) the date (which shall be a Business Day) of issuance of such Letter of Credit (or the date of effectiveness of such extension, modification or amendment) and the stated expiry date thereof (which shall be no later than one year following the date of such issuance), (ii) the proposed stated amount of such Letter of Credit, (iii) the name and address of the beneficiary of such Letter of Credit and (iv) a statement of drawing conditions applicable to such Letter of Credit, and if such Request for Issuance relates to an amendment or modification of a Letter of Credit, it shall be accompanied by the consent of the beneficiary of the Letter of Credit thereto.

20

(c) In the event that any Letter of Credit remains outstanding beyond the fifteenth day prior to the Maturity Date, the Borrower shall either (i) pay to the Agent an amount equal to 103% of the LC Outstandings on the later of such date and the date of issuance of such Letter of Credit, which amount the Agent shall hold in the Cash Collateral Account for the account of the Borrower, without interest, for the purpose of paying any draft presented, with the excess, if any, to be returned to the Borrower upon termination or expiration of such Letter of Credit and payment in full of all amounts due hereunder or (ii) deliver a back-up letter of credit to the Agent securing the Borrower’s reimbursement obligations with respect to such Letter of Credit in form and substance acceptable to the Fronting Bank and the Agent and from a creditworthy financial institution acceptable to the Agent.

Without limiting the scope and nature of each Lender’s participation in any Letter of Credit, to the extent that the Fronting Bank has not been reimbursed as required hereunder or under any such Letter of Credit, each Lender shall pay to the Fronting Bank its Commitment Percentage of such unreimbursed drawing in same day funds on the day of notification by the Fronting Bank of an unreimbursed drawing pursuant to the provisions of subsection (e). The obligation of each Lender so to reimburse the Fronting Bank shall be absolute and unconditional and shall not be affected by the occurrence of a Default, an Event of Default or any other occurrence or event. Any such reimbursement shall not relieve or otherwise impair the obligation of the Borrower to reimburse the Fronting Bank under any Letter of Credit, together with interest as hereinafter provided.

(e) In the event of any drawing under any Letter of Credit, the Fronting Bank will promptly notify the Borrower. Unless the Borrower shall immediately notify the Fronting Bank of its intent otherwise to reimburse the Fronting Bank for any drawing made prior to the Maturity Date, the Borrower shall be deemed to have requested a Base Rate Advance in the amount of such drawing as provided in subsection (f), the proceeds of which will be used to satisfy the reimbursement obligation of the Borrower with respect to such drawing. If, at any time on or after the Maturity Date, any drawing is made under any Letter of Credit, the Fronting Bank shall instruct the Agent to withdraw from the Cash Collateral Account funds in an amount equal to the amount of such drawing, which the Agent shall transfer to the Fronting Bank in order to reimburse the Fronting Bank for such drawing. In the case of any drawing made under any Letter of Credit prior to the Maturity Date, the Borrower shall reimburse the Fronting Bank on the day such drawing is paid either with the proceeds of an Advance obtained hereunder or otherwise in same day funds as provided herein. If the Borrower shall fail to reimburse the Fronting Bank as provided herein, the unreimbursed amount of such drawing shall bear interest at a per annum rate equal to the Base Rate plus two percent (2%) per annum. The Borrower’s reimbursement obligations hereunder shall be absolute and unconditional under all circumstances

21

irrespective of any rights of set-off, counterclaim or defense to payment that the applicable account party or the Borrower may claim or have against the Fronting Bank, the Lenders, the beneficiary of the Letter of Credit drawn upon or any other Person, including, without limitation, any defense based on any failure of the applicable account party or the Borrower to receive consideration or the legality, validity, regularity or unenforceability of the Letter of Credit. The Fronting Bank will promptly notify the Lenders of the amount of any unreimbursed drawing and each Lender shall promptly pay to the Fronting Bank, in immediately available funds, the amount of such Lender’s Commitment Percentage of such unreimbursed drawing. Such payment shall be made on the day such notice is received by such Lender from the Fronting Bank if such notice is received at or before 2:00 p.m., otherwise such payment shall be made at or before 12:00 noon on the Business Day next succeeding the day such notice is received. If such Lender does not pay such amount to the Fronting Bank in full upon such request, such Lender shall, on demand, pay to the Fronting Bank interest on the unpaid amount during the period from the date the Lender received the notice regarding the unreimbursed drawing until the Lender pays such amount to the Fronting Bank in full at a rate per annum equal to, if paid within two Business Days of the date of drawing, the Federal Funds Rate and thereafter at a rate equal to the Base Rate. Each Lender’s obligation to make such payment to the Fronting Bank, and the right of the Fronting Bank to receive the same, shall be absolute and unconditional, shall not be affected by any circumstance whatsoever and without regard to the termination of this Agreement or the Commitments, the existence of a Default or Event of Default or the acceleration of the obligations hereunder and shall be made without any offset, abatement, withholding or reduction whatsoever. Simultaneously with the making of each such payment by a Lender to the Fronting Bank, such Lender shall, automatically and without any further action on the part of the Fronting Bank or such Lender, acquire a participation in an amount equal to such payment (excluding the portion of such payment constituting interest owing to the Fronting Bank) in the related unreimbursed drawing portion of the LC Outstandings and in the interest thereon, and shall have a claim against the Borrower with respect thereto.

(f) On any day on which the Borrower shall have requested, or been deemed to have requested, a Borrowing to reimburse a drawing under a Letter of Credit, the Fronting Bank shall give notice to the Lenders that a Borrowing has been requested or deemed requested in connection with a drawing under a Letter of Credit, in which case an Advance comprised solely of Base Rate Advances (each such borrowing, a “Mandatory Borrowing”) shall be immediately made by all Lenders (without giving effect to any termination of the Commitments pursuant to Section 9.1) pro rata based on each Lender’s Commitment Percentage, and the proceeds thereof shall be paid directly to the Fronting Bank for application to the applicable LC Outstandings. Each Lender hereby irrevocably agrees to make such Base Rate Advances upon any such request or deemed request on account of each such Mandatory Borrowing in the amount and in the manner specified in the preceding sentence and on the same such date notwithstanding (i) the amount of Mandatory Borrowing may not comply with the minimum amount for Borrowings otherwise required hereunder, (ii) whether any conditions specified in Article III are then satisfied, (iii) whether a Default or Event of Default then exists, (iv) failure of any such request or deemed request for a Borrowing to be made by the time otherwise required hereunder, (v) the date of such Mandatory Borrowing, or (vi) any reduction in or any termination of the Commitments. Such funding of Borrowings shall be made on the day notice of such Mandatory Borrowing is received by each Lender from the Fronting Bank if such notice is received at or before 2:00 p.m., otherwise such payment shall be made at or before 12:00 noon on the Business

22

Day next succeeding the day such notice is received. In the event that any Mandatory Borrowing cannot for any reason be made on the date otherwise required above (including, without limitation, as a result of the commencement of a proceeding under any applicable bankruptcy law with respect to the Borrower), then each Lender hereby agrees that it shall forthwith fund (as of the date the Mandatory Borrowing would otherwise have occurred, but adjusted for any payments received from the Borrower on or after such date and prior to such purchase) its Commitment Percentage of the outstanding LC Outstandings; provided, further, that in the event any Lender shall fail to fund its Commitment Percentage on the day the Mandatory Borrowing would otherwise have occurred, then the amount of such Lender’s unfunded Commitment Percentage therein shall bear interest payable to the Fronting Bank upon demand, if paid within two Business Days of such date, at the Federal Funds Rate, and thereafter, at the Base Rate.

(g) The payment obligations of each Lender under subsection (d) and of the Borrower under this Agreement in respect of any payment under any Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances:

(i) any lack of validity or enforceability of any Credit Document or any other agreement or instrument relating thereto or to such Letter of Credit;

(ii) any amendment or waiver of, or any consent to departure from, the terms of any Credit Document or such Letter of Credit;

(iii) the existence of any claim, set-off, defense or other right that the Borrower may have at any time against any beneficiary, or any transferee, of such Letter of Credit (or any persons for whom any such beneficiary or any such transferee may be acting), the Fronting Bank, or any other person, whether in connection with any Credit Document, the transactions contemplated hereby or by such Letter of Credit, or any unrelated transaction;

(iv) any statement or any other document presented under such 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 in good faith by the Fronting Bank under the Letter of Credit issued by the Fronting Bank against presentation of a draft or certificate that does not comply with the terms of such Letter of Credit; or

(vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

(h) The Borrower assumes all risks of the acts and omissions of any beneficiary or transferee of any Letter of Credit. Neither the Fronting Bank, the Lenders nor any of their respective officers, directors, employees, agents or Affiliates shall be liable or responsible for (i) the use that may be made of such Letter of Credit or any acts or omissions of any beneficiary or transferee thereof in connection therewith, (ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged, (iii) payment by the Fronting Bank against

23

presentation of documents that do not comply with the terms of such Letter of Credit, including failure of any documents to bear any reference or adequate reference to such Letter of Credit, or (iv) any other circumstances whatsoever in making or failing to make payment under such Letter of Credit, except that, and notwithstanding subsection (f) and the foregoing clauses (i) through (iii), the Borrower and each Lender shall have the right to bring suit against the Fronting Bank, and the Fronting Bank shall be liable to the Borrower and any Lender, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower or such Lender that the Borrower or such Lender proves were caused by the Fronting Bank’s willful misconduct or gross negligence, including, in the case of the Borrower, the Fronting Bank’s willful failure to make timely payment under such Letter of Credit following the presentation to it by the beneficiary thereof of a draft and accompanying certificate(s) that strictly comply with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, the Fronting Bank may accept sight drafts and accompanying certificates presented under the Letter of Credit issued by the Fronting Bank that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and payment against such documents shall not constitute willful misconduct or gross negligence by the Fronting Bank. Notwithstanding the foregoing, no Lender shall be obligated to indemnify the Borrower for damages caused by the Fronting Bank’s willful misconduct or gross negligence.

ARTICLE III

SECTION 3.2. Prepayments.

(a) Optional Prepayments. The Borrower shall have the right to prepay Advances in whole or in part from time to time without premium or penalty; provided, however, that (i) Eurodollar Advances may be prepaid only on two Business Days’ prior written notice to the Agent, and any prepayment of Eurodollar Advances will be subject to Section 4.3, and (ii) each partial prepayment of Advances shall be in the minimum principal amount of $1,000,000 and in increments of $1,000,000 in excess thereof; provided that if less than $1,000,000 would remain outstanding after such prepayment, such prepayment shall be in the amount of the entire outstanding principal amount of the Advances. Amounts prepaid hereunder shall be applied as the Borrower may elect; provided that if the Borrower fails to specify an optional prepayment then such prepayment shall be applied first to Base Rate Advances, and then to Eurodollar Advances in direct order of Interest Period maturities.

24

(b) Mandatory Prepayments. If at any time the Outstanding Credits exceed the aggregate Commitments, the Borrower shall immediately make a principal payment to the Agent and/or deposit funds in the Cash Collateral Account in respect of LC Outstandings pursuant to Section 9.2(d) for the ratable accounts of the Lenders as shall be necessary in order that the Outstanding Credits (after giving effect to such prepayment) minus the amount held in the Cash Collateral Account after giving effect to such cash collateralization will be less than or equal to the aggregate Commitments. Any payments made under this subsection (b) shall be subject to Section 4.3 and, in the case of principal payments, shall be applied first to Base Rate Advances, and then to Eurodollar Advances in direct order of Interest Period maturities.

SECTION 3.3. Payment in full at Maturity.

On the Maturity Date, the entire outstanding principal balance of all Advances, together with accrued but unpaid interest and all other sums owing under this Agreement, shall be due and payable in full; provided, however, that until the Borrower obtains a Long-Term PSCW Approval (and provides the Agent with a copy thereof), the outstanding principal balance of each Advance, together with accrued but unpaid interest thereon, shall be due and payable in full on the earlier of (i) the date that is 364 days following the date on which such Advance is made and (ii) the Maturity Date.

SECTION 3.4. Fees.

(a) Facility Fee. In consideration of the Commitments being made available by the Lenders hereunder, the Borrower agrees to pay to the Agent, for the pro rata benefit of each Lender, a facility fee at a rate per annum equal to the Facility Fee Percentage in effect from time to time commencing on the date hereof, on the Commitment from time to time of such Lender (regardless of usage), quarterly in arrears, on the last day of each March, June, September and December, on the Maturity Date, and (if applicable) on the date after the Maturity Date on which all Advances and other amounts payable by the Borrower hereunder are paid in full (without regard to any termination of the Commitments on the Maturity Date).

(b) LC Fee. The Borrower agrees to pay the Agent for the account of the Fronting Bank an issuance fee (an “Issuance Fee”) and such other charges as are separately agreed upon with the Fronting Bank, and agrees to pay to the Agent for the account of the Lenders a fee (the “LC Fee”) on the face amount of each Letter of Credit issued by the Fronting Bank calculated at a rate per annum at all times equal to the Applicable Margin in effect for Eurodollar Rate Advances, in each case computed on the basis of the actual number of days that each Letter of Credit is outstanding over a year of 360 days, payable quarterly in arrears on each March 31, June 30, September 30 and December 31, and on the date that such Letter of Credit expires or is drawn in full.

(c) Administrative Fees. The Borrower agrees to pay such other fees as agreed to by the Borrower in the Fee Letters.

SECTION 3.5. Place and Manner of Payments.

All payments of principal, interest, fees, expenses and other amounts to be made by the Borrower under this Agreement shall be received without setoff, deduction or counterclaim not

25

later than 2:00 p.m. on the date when due in Dollars and in immediately available funds by the Agent at its offices in New York, New York. The Borrower shall, at the time it makes any payment under this Agreement, specify to the Agent the Outstanding Credits, fees or other amounts payable by the Borrower hereunder to which such payment is to be applied (and in the event that it fails to specify, or if such application would be inconsistent with the terms hereof, the Agent shall distribute such payment to the Lenders in such manner as it reasonably determines in its sole discretion).

SECTION 3.6. Pro Rata Treatment.

Except to the extent otherwise provided herein, all Borrowings, each payment or prepayment of principal of any Advance, each payment of interest on the Advances, each payment of facility fees, LC Fees, each reduction of the Commitments, and each conversion or continuation of any Advance, shall be allocated pro rata among the Lenders in accordance with the respective Commitment Percentages; provided that, if any Lender shall have failed to fund its applicable pro rata share of any Borrowing, then any amount to which such Lender would otherwise be entitled pursuant to this Section 3.6 shall instead be payable to the Agent until the share of such Borrowing not funded by such Lender has been repaid; and provided, further, that in the event any amount paid to any Lender pursuant to this Section 3.6 is rescinded or must otherwise be returned by the Agent, each Lender shall, upon the request of the Agent, repay to the Agent the amount so paid to such Lender, with interest for the period commencing on the date such payment is returned by the Agent until the date the Agent receives such repayment at a rate per annum equal to, during the period to but excluding the date two Business Days after such request, the Federal Funds Rate, and thereafter, the Base Rate plus two percent per annum.

SECTION 3.7. Computations of Interest and Fees.

(a) Except for Base Rate Advances bearing interest determined under clause (i) of the definition of Base Rate, on which interest shall be computed on the basis of a 365 or 366 day year, as the case may be, all computations of interest and fees hereunder shall be made on the basis of the actual number of days elapsed over a year of 360 days.

(b) It is the intent of the Lenders and the Borrower to conform to and contract in strict compliance with applicable usury law from time to time in effect. All agreements between the Lenders and the Borrower are hereby limited by the provisions of this subsection, which shall override and control all such agreements, whether now existing or hereafter arising and whether written or oral. In no way, nor in any event or contingency (including but not limited to prepayment or acceleration of the maturity of any obligation), shall the interest taken, reserved, contracted for, charged, or received under this Agreement or otherwise exceed the maximum nonusurious amount permissible under applicable law. If, from any possible construction of any of the Credit Documents or any other document, interest would otherwise be payable in excess of the maximum nonusurious amount, any such construction shall be subject to the provisions of this subsection and such documents shall be automatically reduced to the maximum nonusurious amount permitted under applicable law, without the necessity of execution of any amendment or new document. If any Lender shall ever receive anything of value that is characterized as interest on the Advances under applicable law and that would, apart from this provision, be in excess of the maximum lawful amount, an amount equal to the amount that would have been

26

excessive interest shall, without penalty, be applied to the reduction of the principal amount owing on the Advances and not to the payment of interest, or refunded to the Borrower or the other payor thereof if and to the extent such amount that would have been excessive exceeds such unpaid principal amount of the Advances. The right to demand payment of the Advances or any other indebtedness evidenced by any of the Credit Documents does not include the right to receive any interest that has not otherwise accrued on the date of such demand, and the Lenders do not intend to charge or receive any unearned interest in the event of such demand. All interest paid or agreed to be paid to the Lenders with respect to the Advances shall, to the extent permitted by applicable law, be amortized, prorated, allocated, and spread throughout the full stated term (including any renewal or extension) of the Advances so that the amount of interest on account of such indebtedness does not exceed the maximum nonusurious amount permitted by applicable law.

SECTION 3.8. Sharing of Payments.

Each Lender agrees that, in the event that any Lender shall obtain payment in respect of any Extension of Credit or any other obligation owing to such Lender under this Agreement through the exercise of a right of set-off, banker’s lien, counterclaim or otherwise (including, but not limited to, pursuant to the Bankruptcy Code) in excess of its pro rata share as provided for in this Agreement, such Lender shall promptly purchase from the other Lenders a participation in such Extension of Credit and other obligations, in such amounts and with such other adjustments from time to time, as shall be equitable in order that all Lenders share such payment in accordance with their respective ratable shares as provided for in this Agreement. Each Lender further agrees that if a payment to a Lender (which is obtained by such Lender through the exercise of a right of set-off, banker’s lien, counterclaim or otherwise) shall be rescinded or must otherwise be restored, each Lender that shall have shared the benefit of such payment shall, by repurchase of a participation theretofore sold, return its share of that benefit to each Lender whose payment shall have been rescinded or otherwise restored. The Borrower agrees that any Lender so purchasing such a participation may, to the fullest extent permitted by law, exercise all rights of payment, including set-off, banker’s lien or counterclaim, with respect to such participation as fully as if such Lender were a holder of such Advance or other obligation in the amount of such participation. Except as otherwise expressly provided in this Agreement, if any Lender shall fail to remit to the Agent or any other Lender an amount payable by such Lender to the Agent or such other Lender pursuant to this Agreement on the date when such amount is due, such payments shall accrue interest thereon, for each day from the date such amount is due until the day such amount is paid to the Agent or such other Lender, at a rate per annum equal to the Federal Funds Rate. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a setoff to which this Section 3.8 applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders under this Section 3.8 to share in the benefits of any recovery on such secured claim.

SECTION 3.9. Additional Interest on Advances.

The Borrower agrees to pay to each Lender, so long as such Lender shall be required under regulations of the Board of Governors of the Federal Reserve System to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional

27

interest on the unpaid principal amount of each Eurodollar Advance of such Lender, from the date of such Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period for such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Advance. Such additional interest shall be determined by such Lender and notified to the Borrower through the Agent, and such determination shall be conclusive and binding for all purposes, absent manifest error.

SECTION 3.10. Evidence of Debt.

(a) Each Lender shall maintain an account or accounts evidencing each Advance made by such Lender to the Borrower from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement. Each Lender will make reasonable efforts to maintain the accuracy of its account or accounts and to promptly update its account or accounts from time to time, as necessary.

(b) The Agent shall maintain the Register pursuant to Section 11.3(c), and a subaccount for each Lender, in which Register and subaccounts (taken together) shall be recorded (i) the amount, type and Interest Period of each such Advance hereunder, (ii) the amount of any principal or interest due and payable or to become due and payable to each Lender hereunder and (iii) the amount of any sum received by the Agent hereunder from or for the account of the Borrower and each Lender’s share thereof. The Agent will make reasonable efforts to maintain the accuracy of the subaccounts referred to in the preceding sentence and to promptly update such subaccounts from time to time, as necessary.

(c) The entries made in the accounts, Register and subaccounts maintained pursuant to subsection (b) (and, if consistent with the entries of the Agent, subsection (a)) shall be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, however, that the failure of any Lender or the Agent to maintain any such account, such Register or such subaccount, as applicable, or any error therein, shall not in any manner affect the obligation of the Borrower to repay the Advances made by such Lender in accordance with the terms hereof.

(d) Any Lender may request that its Advances be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note, in a form acceptable to the Agent, payable to the order of such Lender. Thereafter, the Advances evidenced by such promissory note and interest thereon shall at all times (including after any assignment pursuant to Section 11.3) be represented by one or more promissory notes payable to the order of the payee named therein or any assignee pursuant to Section 11.3, except to the extent that any such Lender or assignee subsequently returns any such promissory note for cancellation and requests that such Advances once again be evidenced as described in subsections (a) and (b) above.

28

ARTICLE IV

ADDITIONAL PROVISIONS REGARDING ADVANCES

SECTION 4.1. Eurodollar Borrowing Provisions.

(a) Unavailability. In the event that the Agent shall have determined in good faith (i) that Dollar deposits in the principal amounts requested with respect to a Eurodollar Borrowing are not generally available in the London interbank Eurodollar market or (ii) that reasonable means do not exist for ascertaining the Eurodollar Rate, the Agent shall, as soon as practicable thereafter, give notice of such determination to the Borrower and the Lenders. In the event of any such determination under clause (i) or (ii) above, until the Agent shall have advised the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (A) any request by the Borrower for Eurodollar Borrowings shall be deemed to be a request for Base Rate Borrowings, (B) any request by the Borrower for conversion into or continuation of Eurodollar Borrowings shall be deemed to be a request for conversion into or continuation of Base Rate Borrowings and (C) any Borrowings that were to be converted or continued as Eurodollar Borrowings on the first day of an Interest Period shall be converted to or continued as Base Rate Borrowings.

(b) Change in Legality. Notwithstanding any other provision herein, if any change, after the date hereof, in any law or regulation (including the introduction of any new law or regulation) or in the interpretation thereof by any Governmental Authority charged with the administration or interpretation thereof shall make it unlawful for any Lender to make or maintain any Eurodollar Advance or to give effect to its obligations as contemplated hereby with respect to any Eurodollar Advance, then, by written notice to the Borrower and to the Agent, such Lender may:

(i) declare that Eurodollar Advances, and conversions to or continuations of Eurodollar Advances, will not thereafter be made by such Lender hereunder, whereupon any request by the Borrower for, or for conversion into or continuation of, Eurodollar Borrowings shall, as to such Lender only, be deemed a request for, or for conversion into or continuation of, Base Rate Borrowings, unless such declaration shall be subsequently withdrawn; and

(ii) require that all outstanding Eurodollar Advances made by it be converted to Base Rate Advances in which event all such Eurodollar Advances shall be automatically converted to Base Rate Advances.

In the event any Lender shall exercise its rights under clause (i) or (ii) above, all payments and prepayments of principal that would otherwise have been applied to repay the Eurodollar Advances that would have been made by such Lender or the converted Eurodollar Advances of such Lender shall instead be applied to repay the Base Rate Advances made by such Lenders in lieu of, or resulting from the conversion of, such Eurodollar Advances.

(c) Requirements of Law. If at any time a Lender shall incur increased costs or reductions in the amounts received or receivable hereunder with respect to the making, the commitment to make or the maintaining of any Eurodollar Advance because of (i) any change,

29

after the date hereof, in any applicable law, governmental rule, regulation, guideline or order (or in the interpretation or administration thereof and including the introduction of any new law or governmental rule, regulation, guideline or such order) including, without limitation, the imposition, modification or deemed applicability of any reserves, deposits or similar requirements (such as, for example, but not limited to, a change in official reserve requirements, but, in all events, excluding reserves required under Regulation D to the extent included in the computation of additional interest under Section 3.9) or (ii) other circumstances affecting the London interbank Eurodollar market, then the Borrower shall pay to such Lender promptly upon written demand therefor, such additional amounts (in the form of an increased rate of, or a different method of calculating, interest or otherwise as such Lender may determine in its sole discretion) as may be required to compensate such Lender for such increased costs or reductions in amounts receivable hereunder.

Each determination and calculation made by a Lender under this Section 4.1 shall, absent manifest error, be binding and conclusive on the parties hereto. Any conversions of Eurodollar Advances made pursuant to this Section 4.1 shall subject the Borrower to the payments required by Section 4.3. This Section shall survive termination of this Agreement and the other Credit Documents and payment of the Advances and all other amounts payable hereunder.

SECTION 4.2. Capital Adequacy.

If any Lender has determined that the adoption or effectiveness, after the date hereof, of any applicable law, rule or regulation regarding capital adequacy, or any change therein (after the date hereof), 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 such Lender (or its parent corporation) 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, has or would have the effect of reducing the rate of return on such Lender’s (or parent corporation’s) capital or assets as a consequence of its commitments or obligations hereunder to a level below that which such Lender (or its parent corporation) could have achieved but for such adoption, effectiveness, change or compliance (taking into consideration such Lender’s (or parent corporation’s) policies with respect to capital adequacy), then, upon notice from such Lender, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction. Each determination by any such Lender of amounts owing under this Section 4.2 shall, absent manifest error, be conclusive and binding on the parties hereto. This Section shall survive termination of this Agreement and the other Credit Documents and payment of the Advances and all other amounts payable hereunder.

SECTION 4.3. Compensation.

The Borrower promises to indemnify each Lender and to hold each Lender harmless from any loss or expense that such Lender may sustain or incur as a consequence of (i) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Advances after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (ii) default by the Borrower in making any prepayment of a Eurodollar Advance after the Borrower has given a notice thereof in accordance with the provisions of this

30

Agreement, (iii) the making of a prepayment of Eurodollar Advances on a day that is not the last day of an Interest Period with respect thereto and (iv) the payment, continuation or conversion of a Eurodollar Advance on a day that is not the last day of the Interest Period applicable thereto or the failure to repay a Eurodollar Advance when required by the terms of this Agreement. Such indemnification may include such additional amount or amounts as will compensate such Lender for such loss or expense actually sustained or incurred by such Lender. The agreements in this Section shall survive the termination of this Agreement and the payment of the Advances and all other amounts payable hereunder.

SECTION 4.4. Taxes.

(a) Except as provided below in this Section 4.4, all payments made by the Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any court or governmental body, agency or other official, excluding taxes measured by or imposed upon the net income of any Lender or its applicable lending office, or any branch or affiliate thereof, and all franchise taxes, branch taxes, taxes on doing business or taxes on the capital or net worth of any Lender or its applicable lending office, or any branch or affiliate thereof, in each case imposed in lieu of net income taxes (i) by the jurisdiction under the laws of which such Lender, applicable lending office, branch or affiliate is organized or is located, or in which its principal executive office is located, or any nation within which such jurisdiction is located or any political subdivision thereof or (ii) by reason of any connection between the jurisdiction imposing such tax and such Lender, applicable lending office, branch or affiliate other than a connection arising solely from such Lender having executed, delivered or performed its obligations, or received payment under or enforced, this Agreement. If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) are required to be withheld from any amounts payable to an Agent or any Lender hereunder, (A) the amounts so payable to the Agent or such Lender shall be increased to the extent necessary to yield to the Agent or such Lender (after payment of all Non-Excluded Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement and any promissory notes, provided, however, that the Borrower shall be entitled to deduct and withhold any Non-Excluded Taxes and shall not be required to increase any such amounts payable to any Lender that is not organized under the laws of the United States of America or a state thereof if such Lender fails to comply with the requirements of subsection (b) whenever any Non-Excluded Taxes are payable by the Borrower, and (B) as promptly as possible after requested, the Borrower shall send to the Agent for its own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded Taxes when due to the appropriate taxing authority or fails to remit to the Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Agent and any Lender for any incremental Non-Excluded Taxes, interest or penalties that may become payable by the Agent or any Lender as a result of any such failure. The agreements in this Section shall survive the termination of this Agreement and the payment of the Borrowings and all other amounts payable hereunder.

31

(b) Each Lender that is not incorporated under the laws of the United States of America or a state thereof shall:

(i) (A) on or before the date of any payment by the Borrower under this Agreement to such Lender, deliver to the Borrower and the Agent (x) two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI, or successor applicable form, as the case may be, certifying that it is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes and (y) an Internal Revenue Service Form W-8 or W-9, or successor applicable form, as the case may be, certifying that it is entitled to an exemption from United States backup withholding tax; (B) deliver to the Borrower and the Agent two further copies of any such form or certification on or before the date that any such form or certification expires or becomes obsolete and after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrower; and (C) obtain such extensions of time for filing and complete such forms or certifications as may reasonably be requested by the Borrower or the Agent; or

(ii) in the case of any such Lender that is not a “bank” within the meaning of Section 881(c)(3)(A) of the Internal Revenue Code, (A) represent to the Borrower (for the benefit of the Borrower and the Agent) that it is not a bank within the meaning of Section 88l(c)(3)(A) of the Internal Revenue Code, (B) agree to furnish to the Borrower, on or before the date of any payment by the Borrower, with a copy to the Agent, two accurate and complete original signed copies of Internal Revenue Service Form W-8, or successor applicable form certifying to such Lender’s legal entitlement at the date of such certificate to an exemption from U.S. withholding tax under the provisions of Section 881(c) of the Internal Revenue Code with respect to payments to be made under this Agreement (and to deliver to the Borrower and the Agent two further copies of such form on or before the date it expires or becomes obsolete and after the occurrence of any event requiring a change in the most recently provided form and, if necessary, obtain any extensions of time reasonably requested by the Borrower or the Agent for filing and completing such forms), and (C) agree, to the extent legally entitled to do so, upon reasonable request by the Borrower, to provide to the Borrower (for the benefit of the Borrower and the Agent) such other forms as may be reasonably required in order to establish the legal entitlement of such Lender to an exemption from withholding with respect to payments under this Agreement.

Notwithstanding the above, if any change in treaty, law or regulation has occurred after the date such Person becomes a Lender hereunder which renders all such forms inapplicable or that would prevent such Lender from duly completing and delivering any such form with respect to it and such Lender so advises the Borrower and the Agent, then such Lender shall be exempt from such requirements. Each Person that shall become a Lender or a participant of a Lender pursuant to Section 11.3 shall, upon the effectiveness of the related transfer, be required to provide all of the forms, certifications and statements required pursuant to this subsection (b); provided that in the case of a participant of a Lender, the obligations of such participant of a Lender pursuant to this subsection (b) shall be determined as if the participant of a Lender were a Lender except that such participant of a Lender shall furnish all such required forms, certifications and statements to the Lender from which the related participation shall have been purchased.

32

SECTION 9.2. Acceleration; Remedies.

Upon the occurrence of an Event of Default, and at any time thereafter unless and until such Event of Default has been waived by the Required Lenders (or the Lenders as may be required hereunder) the Agent may, and shall, upon the request and direction of the Required Lenders, by written notice to the Borrower take any of the following actions without prejudice to the rights of the Agent or any Lender to enforce its claims against the Borrower, except as otherwise specifically provided for herein:

(a) Termination of the Commitments. Declare the Commitments terminated whereupon the Commitments shall be immediately terminated.

(b) Acceleration of Advances. Declare the unpaid amount of all Advances and all other amounts payable by the Borrower hereunder to be due whereupon the same shall be immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower.

47

(c) Enforcement of Rights. Enforce any and all rights and interests created and existing under the Credit Documents, including, without limitation, all rights of set-off.

(d) Cash Collateralization of LC Outstandings. Notwithstanding anything to the contrary contained herein, no notice given or declaration made by the Agent pursuant to this Article IX shall affect (i) the obligation of the Fronting Bank to make any payment under any Letter of Credit in accordance with the terms of such Letter of Credit or (ii) the obligations of each Lender in respect of each such Letter of Credit; provided, however, that if an Event of Default has occurred and is continuing, the Agent shall at the request, or may with the consent, of the Required Lenders, upon notice to the Borrower, require the Borrower to deposit with the Agent an amount in the cash collateral account (the “Cash Collateral Account”) described below equal to the LC Outstandings on such date. Such Cash Collateral Account shall at all times be free and clear of all rights or claims of third parties. The Cash Collateral Account shall be maintained with the Agent in the name of, and under the sole dominion and control of, the Agent, and amounts deposited in the Cash Collateral Account shall bear interest at a rate equal to the rate generally offered by the Agent for deposits equal to the amount deposited by the Borrower in the Cash Collateral Account, for a term to be determined by the Agent, in its sole discretion. The Borrower hereby grants to the Agent for the benefit of the Fronting Bank and the Lenders a Lien in and hereby assigns to the Agent for the benefit of the Fronting Bank and the Lenders all of its right, title and interest in, the Cash Collateral Account and all funds from time to time on deposit therein to secure its reimbursement obligations in respect of Letters of Credit. If any drawings then outstanding or thereafter made are not reimbursed in full immediately upon demand or, in the case of subsequent drawings, upon being made, then, in any such event, the Agent may apply the amounts then on deposit in the Cash Collateral Account, toward the payment in full of any of the obligations as and when such obligations shall become due and payable. Upon payment in full, after the termination of the Letters of Credit, of all such obligations, the Agent will repay and reassign to the Borrower any cash then in the Cash Collateral Account and the Lien of the Agent on the Cash Collateral Account and the funds therein shall automatically terminate. In addition, at any time the Borrower is required under Section 2.8(c) or 3.2(b) to cash collateralize any of the LC Outstandings, the Borrower shall deposit such amount in the Cash Collateral Account. If, at any time no Event of Default has occurred and is continuing and the cash on deposit in the Cash Collateral Account shall exceed the LC Outstandings, then the Agent will repay and reassign to the Borrower cash in an amount equal to such excess, and the Lien of the Agent on such cash shall automatically terminate.

(e) Notwithstanding the foregoing, if an Event of Default specified in Section 9.1(e) shall occur, then the Commitments shall automatically terminate and all Advances, all accrued interest in respect thereof, all accrued and unpaid fees and other indebtedness or obligations owing to the Lenders and the Agent hereunder shall immediately become due and payable without the giving of any notice or other action by the Agent or the Lenders.

(f) Notwithstanding the fact that enforcement powers reside primarily with the Agent, each Lender has, to the extent permitted by law, a separate right of payment and shall be considered a separate “creditor” holding a separate “claim” within the meaning of Section 101(5) of the Bankruptcy Code or any other insolvency statute.

48

SECTION 9.3. Allocation of Payments After Event of Default.

Notwithstanding any other provisions of this Agreement, after the occurrence of an Event of Default, all amounts collected or received by the Agent or any Lender on account of amounts outstanding under any of the Credit Documents shall be paid over or delivered as follows:

FIRST, to the payment of all reasonable out-of-pocket costs and expenses (including without limitation reasonable attorneys’ fees) of the Agent or any of the Lenders in connection with enforcing the rights of the Lenders under the Credit Documents, pro rata as set forth below;

SECOND, to payment of any fees owed to the Agent or any Lender, pro rata as set forth below;

THIRD, to the payment of all accrued interest payable to the Lenders hereunder, pro rata as set forth below;

FOURTH, to the payment or cash collateralization, as applicable, of the Outstanding Credits, pro rata as set forth below;

FIFTH, to all other obligations that shall have become due and payable under the Credit Documents and not repaid pursuant to clauses “FIRST” through “THIRD” above; and

SIXTH, to the payment of the surplus, if any, to whoever may be lawfully entitled to receive such surplus.

In carrying out the foregoing, (i) amounts received shall be applied in the numerical order provided until exhausted prior to application to the next succeeding category; and (ii) each of the Lenders shall receive an amount equal to its pro rata share (based on the proportion that the then Outstanding Credits held by such Lender bears to the aggregate then outstanding Advances of amounts available to be applied.

SECTION 10.4. Reliance on Communications.

The Agent shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document or conversation believed by it in

50

good faith to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Borrower, independent accountants and other experts selected by the Agent with reasonable care). The Agent may deem and treat the Lenders as the owner of its interests hereunder for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Agent in accordance with Section 11.3(b). The Agent shall be fully justified in failing or refusing to take any action under this Agreement or under any of the other Credit Documents unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder or under any of the other Credit Documents in accordance with a request of the Required Lenders (or to the extent specifically provided in Section 11.6, all the Lenders) and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders (including their successors and assigns).

SECTION 10.5. Notice of Default.

The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the Agent has received notice from a Lender or the Borrower referring to the Credit Document, describing such Default or Event of Default and stating that such notice is a “notice of default”. In the event that the Agent receives such a notice, the Agent shall give prompt notice thereof to the Lenders. The Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders.

SECTION 10.6. Non-Reliance on Agent and Other Lenders.

Each Lender and the Fronting Bank expressly acknowledges that neither the Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates has made any representations or warranties to it and that no act by the Agent or any affiliate thereof hereinafter taken, including any review of the affairs of the Borrower, shall be deemed to constitute any representation or warranty by the Agent to any Lender or the Fronting Bank. Each Lender and the Fronting Bank represents to the Agent that it has, independently and without reliance upon the Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, assets, operations, property, financial and other conditions, prospects and creditworthiness of the Borrower and made its own decision to make its Extensions of Credit hereunder and enter into this Agreement. Each Lender and the Fronting Bank also represents that it will, independently and without reliance upon the Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement, and to make such investigation as it deems necessary to inform itself as to the business, assets, operations, property, financial and other conditions, prospects and creditworthiness of the Borrower. Except for notices, reports and other documents expressly required to be furnished to the Lenders and the Fronting Bank by the Agent hereunder, the Agent shall not have any duty or responsibility to provide any Lender or the Fronting Bank with any credit or other information concerning the business, operations,

51

assets, property, financial or other conditions, prospects or creditworthiness of the Borrower that may come into the possession of the Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates.

SECTION 10.7. Indemnification.

If any indemnity furnished to the Agent for any purpose shall, in the opinion of the Agent, be insufficient or become impaired, the Agent may call for additional indemnity and cease, or not commence, to do the acts indemnified against until such additional indemnity is furnished. The agreements in this Section 10.7 shall survive the payment of the Advances and all other amounts payable hereunder.

SECTION 10.8. Agent in Its Individual Capacity.

The Agent in its individual capacity and its Affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Borrower as though the Agent were not Agent hereunder. With respect to the Advances made and all obligations of the Borrower owing to the Agent, the Agent in its individual capacity shall have the same rights and powers under this Agreement as any Lender and may exercise the same as though they were not Agent, and the terms “Lender” and “Lenders” shall include Citibank in its individual capacity.

SECTION 10.9. Successor Agent.

The Agent may, and at the request of the Required Lenders shall, resign as the Agent upon 30 days notice to the Lenders and the Fronting Bank. If the Agent resigns under this Agreement, the Required Lenders and the Fronting Bank shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall be approved by the Borrower so long as no Event of Default has occurred and is continuing. If no successor agent is appointed prior to the effective date of the resignation of the Agent, the Agent may appoint, after consulting with the Lenders and the Borrower, a successor agent from among the Lenders. Upon the acceptance of its appointment as successor agent hereunder, such successor agent shall succeed to all the rights, powers and duties of the retiring Agent, and the term “Agent” shall mean such successor agent and the retiring Agent’s appointment, powers and duties as Agent shall be terminated. After any retiring Agent’s resignation hereunder as Agent, the provisions of this

52

Section 10 and Section 11.5 shall inure to its benefit as to any actions taken or omitted to be taken, by it while it was the Agent under this Agreement. If no successor agent has accepted appointment as the Agent by the date that is 30 days following a retiring Agent’s notice of resignation, the retiring Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above.

(f) Nonrestricted Assignments. Notwithstanding any other provision set forth in this Agreement:

(i) any Lender may at any time, without the consent of the Borrower or the Agent, assign all or any portion of its rights under the Credit Documents to any Federal Reserve Bank as security. No such assignment shall release the assigning Lender from its obligations hereunder;

(ii) any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”) of such Granting Lender identified as such in writing from time to time by the Granting Lender to the Agent and the Borrower, the option to provide to the Borrower all or any part of any Extension of Credit that such Granting Lender would otherwise be obligated to make to such Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any such SPC to make any Extension of Credit, (ii) if such SPC elects not to exercise such option or otherwise fails to provide all or any part of such Extension of Credit, the Granting Lender shall be obligated to make such Extension of Credit pursuant to the terms hereof and (iii) no SPC or Granting Lender shall be entitled to receive any greater amount pursuant to Section 4.1(c) or 4.4 than the Granting Lender would have been entitled to receive had the Granting Lender not otherwise granted such SPC the option to provide any Extension of Credit to the Borrower. The making of an Extension of Credit by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Extension of Credit were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender would otherwise be liable so long as, and to the extent that, the related Granting Lender provides such indemnity or makes such payment. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against or join any other person in instituting against such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. Notwithstanding the foregoing, the Granting Lender unconditionally agrees to indemnify the Borrower, the Agent, the Fronting Bank and each Lender against all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be incurred by or asserted against the Borrower, the Agent, the Fronting Bank or such Lender, as the case may be, in any way relating to or arising as a consequence of any such forbearance or delay in the initiation of any such proceeding against its SPC. Each party hereto hereby acknowledges and agrees that no SPC shall have the rights of a Lender hereunder, such rights being retained by the applicable Granting Lender. Accordingly, and without limiting the foregoing, each party hereby further acknowledges and agrees that no SPC shall have any voting rights hereunder and that the voting rights attributable to any Extension of Credit made by an SPC shall be exercised only by the relevant Granting Lender and that each Granting Lender shall serve as the administrative agent and attorney-in-fact for its SPC and shall on behalf of its SPC receive any and all payments made for the benefit of such SPC and take all actions hereunder to the extent, if any, such

56

SPC shall have any rights hereunder. In addition, notwithstanding anything to the contrary contained in this Agreement, any SPC may (i) with notice to, but without the prior written consent of any other party hereto, assign all or a portion of its interest in any Extension of Credit to the Granting Lender and (ii) disclose on a confidential basis any information relating to its Extensions of Credit to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This Section may not be amended without the prior written consent of each Granting Lender, all or any part of whose Extension of Credit is being funded by an SPC at the time of such amendment; and

(iii) any Lender at any time may assign all or any portion of its rights and obligations under this Agreement to any Affiliate or Approved Fund of such Lender, provided such assignment does not result in the incurrence of any increased payment obligations by any Borrower under Section 4.2 or 4.4. Upon execution, delivery, and acceptance of such Assignment Agreement, the assignee thereunder shall be a party hereto and, to the extent of such assignment, have the obligations, rights, and benefits of a Lender hereunder and the assigning Lender shall, to the extent of such assignment, relinquish its rights and be released from its obligations under this Agreement. If the assignee is not incorporated under the laws of the United States of America or a state thereof, it shall deliver to the Borrower and the Agent certification as to exemption from deduction or withholding of taxes in accordance with Section 4.4.

(g) Information. Any Lender may furnish any information concerning the Borrower in the possession of such Lender from time to time to assignees and participants (including prospective assignees and participants) or to any party that such Lender has engaged or proposes to engage in any swap, securitization or derivative transaction involving any of such Lender’s rights or obligations hereunder.

SECTION 11.4. No Waiver; Remedies Cumulative.

No failure or delay on the part of the Agent, the Fronting Bank or any Lender in exercising any right, power or privilege hereunder or under any other Credit Document and no course of dealing between the Borrower and the Agent, the Fronting Bank or any Lender shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege hereunder or under any other Credit Document preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. The rights and remedies provided herein are cumulative and not exclusive of any rights or remedies that the Agent, the Fronting Bank or any Lender would otherwise have. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Agent, the Fronting Bank or the Lenders to any other or further action in any circumstances without notice or demand.

SECTION 11.5. Payment of Expenses, etc.

The Borrower agrees to: (i) pay all reasonable out-of-pocket costs and expenses of the Agent in connection with (A) the negotiation, preparation, execution and delivery and

57

administration of this Agreement and the other Credit Documents and the documents and instruments referred to therein (including, without limitation, legal fees of the Agent) and (B) any amendment, waiver or consent relating hereto and thereto including, but not limited to, any such amendments, waivers or consents resulting from or related to any work-out, renegotiation or restructure relating to the performance by the Borrower under this Agreement; (ii) pay all reasonable out-of-pocket costs and expenses of the Agent, the Fronting Bank and the Lenders in connection with (A) enforcement of the Credit Documents and the documents and instruments referred to therein (including, without limitation, in connection with any such enforcement, the reasonable fees and disbursements of counsel for the Agent, the Fronting Bank and each of the Lenders) and (B) any bankruptcy or insolvency proceeding of the Borrower; and (iii) indemnify the Agent, the Fronting Bank and each Lender, its affiliates, officers, directors, employees, advisors and agents from and hold each of them harmless against any and all losses, liabilities, claims, damages or expenses incurred by any of them as a result of, or arising out of, or in any way related to, or by reason of, any investigation, litigation or other proceeding (whether or not the Agent or any Lender is a party thereto) related to the entering into and/or performance of any Credit Document or the use of proceeds of any Extension of Credit hereunder or the consummation of any other transactions contemplated in any Credit Document, including, without limitation, the reasonable fees and disbursements of counsel incurred in connection with any such investigation, litigation or other proceeding (but excluding any such losses, liabilities, claims, damages or expenses to the extent incurred by reason of gross negligence or willful misconduct on the part of the Person to be indemnified). Such expenses shall be reimbursed by the Borrower upon presentation of a statement of account, which statement shall be conclusive absent manifest error.

SECTION 11.6. Amendments, Waivers and Consents.

Neither this Agreement, nor any other Credit Document nor any of the terms hereof or thereof may be amended, changed, waived, discharged or terminated unless such amendment, change, waiver, discharge or termination is in writing and signed by the Required Lenders and the Borrower; provided that no amendment, waiver or consent shall, unless in writing and signed by the Fronting Bank in addition to the Required Lenders and the Borrower, affect the rights or duties of the Fronting Bank under this Agreement or any other Credit Document, and provided further, that no such amendment, change, waiver, discharge or termination shall without the consent of each Lender affected thereby:

(a) extend the Maturity Date, or postpone or extend the time for any payment or prepayment of principal, except as provided in Section 2.7;

(b) reduce the rate or extend the time of payment of interest (other than as a result of waiving the applicability of any post-default increase in interest rates) thereon or fees or other amounts payable hereunder;

(c) reduce or waive the principal amount of any Advance;

(d) increase or extend the Commitment (it being understood and agreed that a waiver of any Default or Event of Default shall not constitute a change in the terms of any Commitment of any Lender);

58

(e) release the Borrower from its obligations under the Credit Documents;

(f) amend, modify or waive any provision of this Section 11.6 or Section 3.6, 3.8, 4.1, 4.2, 4.3, 4.4, 9.1(a), 11.2, 11.3 or 11.5;

(g) reduce any percentage specified in, or otherwise modify, the definition of Required Lenders; or

(h) consent to the assignment or transfer by the Borrower of any of its rights and obligations under (or in respect of) the Credit Documents.

Notwithstanding the foregoing, this Agreement may be amended and restated without the consent of any Lender or the Agent if, upon giving effect to such amendment and restatement, such Lender or the Agent, as the case may be, shall no longer be a party to this Agreement (as so amended and restated) or have any Commitment or other obligation hereunder and shall have been paid in full all amounts payable hereunder to such Lender or the Agent, as the case may be. No provision of Section 10 may be amended or modified without the consent of the Agent.

Notwithstanding the fact that the consent of all the Lenders is required in certain circumstances as set forth above, each Lender is entitled to vote as such Lender sees fit on any reorganization plan that affects the Extensions of Credit, and each Lender acknowledges that the provisions of Section 1126(c) of the Bankruptcy Code supersedes the unanimous consent provisions set forth herein.

SECTION 11.7. Counterparts/Telecopy.

This Agreement may be executed in any number of counterparts, each of which where so executed and delivered shall be an original, but all of which shall constitute one and the same instrument. Delivery of executed counterparts by telecopy shall be as effective as an original and shall constitute a representation that an original will be delivered.

SECTION 11.8. Headings.

The headings of the Sections and subsections hereof are provided for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement.

SECTION 11.9. Defaulting Lender.

Each Lender understands and agrees that if such Lender is a Defaulting Lender then it shall not be entitled to vote on any matter requiring the consent of the Required Lenders or to object to any matter requiring the consent of all the Lenders; provided, however, that all other benefits and obligations under the Credit Documents shall apply to such Defaulting Lender.

SECTION 11.10. Confidentiality.

Each of the Agent, each Lender and the Fronting Bank agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed by such Person (i) to its Affiliates and to its and its Affiliates’ respective partners, directors,

59

officers, employees, agents, advisors and other representatives (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (ii) to the extent requested by any regulatory authority purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (iii) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (iv) to any other party hereto, (v) in connection with the exercise of any remedies hereunder or under any other Credit Document or any action or proceeding relating to this Agreement or any other Credit Document or the enforcement of rights hereunder or thereunder, (vi) subject to an agreement containing provisions substantially the same as those of this Section, to (A) any assignee of or participant, or any prospective assignee of or participant in, any of its rights or obligations under this Agreement or (B) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower and its obligations, (vii) with the consent of the Borrower or (viii) to the extent such Information (A) becomes publicly available other than as a result of a breach of this Section or (B) becomes available to the Agent, any Lender, the Fronting Bank or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrower. Notwithstanding anything in this Agreement to the contrary, the Borrower, the Agent, the Fronting Bank and each Lender (and each officer, director, employee, agent and advisor of each such Person) shall not be limited from disclosing the US tax treatment or the US tax structure of the transactions contemplated hereby. For purposes of this Section, “Information” means all information received from the Borrower or any of its Subsidiaries relating to the Borrower or any of its Subsidiaries or any of their respective businesses, other than any such information that is available to the Agent, any Lender or the Fronting Bank on a nonconfidential basis prior to disclosure by the Borrower or any of its Subsidiaries, provided that, in the case of information received from the Borrower or any of its Subsidiaries after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

SECTION 11.11. Survival of Indemnification and Representations and Warranties.

All indemnities set forth herein and all representations and warranties made herein shall survive the execution and delivery of this Agreement, the making of Extensions of Credit and the repayment of the Borrowings and other obligations and the termination of the Commitments hereunder.
