Notes to Condensed Consolidated Financial Statements

(unaudited)

(Reference is made to Notes to Consolidated Financial Statements

included in the Company’s 2004 Annual Report on Form 10-K)

(1)	MANAGEMENT’S STATEMENT

The financial statements included herein have been prepared by Black Hills Corporation (the Company) without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations; however, the Company believes that the footnotes adequately disclose the information presented. These financial statements should be read in conjunction with the financial statements and the notes thereto, included in the Company’s 2004 Annual Report on Form 10-K filed with the Securities and Exchange Commission.

Accounting methods historically employed require certain estimates as of interim dates. The information furnished in the accompanying financial statements reflects all adjustments which are, in the opinion of management, necessary for a fair presentation of the March 31, 2005, December 31, 2004 and March 31, 2004 financial information and are of a normal recurring nature. The results of operations for the three months ended March 31, 2005, are not necessarily indicative of the results to be expected for the full year. All earnings per share amounts discussed refer to diluted earnings per share unless otherwise noted.

(2)	RECLASSIFICATIONS

Certain 2004 amounts in the financial statements have been reclassified to conform to the 2005 presentation. These reclassifications did not have an effect on the Company’s total stockholders’ equity or net income available for common stock as previously reported.

(3)	STOCK-BASED COMPENSATION

At March 31, 2005, the Company had three stock-based employee compensation plans under which it can issue stock options to its employees. The Company accounts for these plans under the recognition and measurement principles of Accounting Principles Board (APB) Opinion No. 25, “Accounting for Stock Issued to Employees (APB 25),” and related interpretations. No employee compensation cost related to stock options is reflected in net income, as all options granted under these plans had an exercise price equal to the market value of the underlying common stock on the date of grant.

The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of Statement of Financial Accounting Standards (SFAS) No. 123, “Accounting for Stock-Based Compensation (SFAS 123),” to stock-based employee compensation (in thousands, except per share amounts):

(4)	RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

SFAS No. 123 (Revised 2004)

In December 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 123 (Revised 2004) “Share Based Payment” (SFAS 123 (Revised 2004)). SFAS 123 (Revised 2004) requires the measurement and recognition of the cost of employee services received in exchange for an award of equity instruments, based on the grant-date fair value of the award. The cost is to be recognized over the requisite service period. In April 2005, the Securities and Exchange Commission (SEC) adopted a final rule amending the effective date of SFAS 123 (Revised 2004) to the first interim or annual reporting period of the fiscal year beginning after June 15, 2005. The Company currently accounts for its employee equity compensation stock option plans under the provisions of APB No. 25 and no stock-based employee compensation cost is reflected in net income (see Note 3, Stock-Based Compensation). The effect of adoption of SFAS 123 (Revised 2004) will be to recognize compensation expense for the fair value of the stock options granted at the grant date. Total stock-based employee compensation expense, net of related tax effects would have been $0.1 million and $0.2 million for the three month periods ending March 31, 2005 and 2004, respectively, had the Company applied the fair value recognition provisions of SFAS 123 during those periods.

FIN 47

In March 2005 the FASB issued FIN 47, “Accounting for Conditional Asset Retirement Obligations.” This interpretation clarifies that the term conditional asset retirement obligation as used in FASB Statement No. 143, “Accounting for Asset Retirement Obligations,” (SFAS 143) refers to 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 obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and (or) method of settlement. Thus, the timing and (or) method of settlement may be conditional on a future event. Accordingly, an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value of the liability can be reasonably estimated. The fair value of a liability for the conditional asset retirement obligation should be recognized when incurred – generally upon acquisition, construction, or development and (or) through the normal operation of the asset. Uncertainty about the timing and (or) method of settlement of a conditional asset retirement obligation should be factored into the measurement of the liability when sufficient information exists.

The Company has identified legal retirement obligations related to plugging and abandonment of natural gas and oil wells in our Oil and gas segment and reclamation of our coal mining sites in our Coal mining segment. FIN 47 is effective for fiscal years ending after December 15, 2005. The Company is currently evaluating the effect of FIN 47 on the Company’s consolidated results of operations, financial position and cash flows.

EITF Issue No. 04-6

On March 17, 2005, the Emerging Issues Task Force (EITF) issued EITF Issue No. 04-6, “Accounting for Stripping Costs Incurred during Production in the Mining Industry” (EITF 04-6). EITF 04-6 provides that stripping costs incurred during the production phase of a mine are variable production costs that should be included in the costs of the inventory produced during the period that the stripping costs are incurred. EITF 04-6 is effective for the first reporting period in fiscal years beginning after December 15, 2005. The Company is currently evaluating the effect of EITF 04-6 on the Company’s consolidated results of operations, financial position and cash flows.

(7)	RECOVERED/RECOVERABLE PURCHASED ELECTRIC AND GAS ENERGY COSTS –

NET

Cheyenne Light, Fuel and Power (CLF&P) recovers purchased power and natural gas costs from customers through an electric cost adjustment (ECA) and a gas cost adjustment (GCA) mechanism. The ECA and GCA rate structure provides for a fixed energy supply rate charged to CLF&P’s customers through 2005; the continuation of the ECA and GCA with certain modifications, including the amortization through December 2005 of unrecovered costs incurred during 2001 up to the agreed upon fixed supply rates; and an agreement that CLF&P’s energy supply needs will be provided, in whole or in part, by Public Service Company of Colorado (PSCo) in accordance with wholesale tariff rates. In 2005, CLF&P will request recovery of its actual cost incurred plus the outstanding balance of any deferral from earlier years. New cost levels have been reflected in CLF&P’s expenses, and in deferred costs based on current ECA and GCA recovery levels, with an effective date of June 1, 2001, and retroactive adjustments back to the date of the increase in costs on February 25, 2001. At March 31, 2005, the ECA and GCA deferred balance is $8.4 million and is included in "Other" under "Other assets" on the accompanying Condensed Consolidated Balance Sheet.

(8)	EARNINGS PER SHARE

Basic earnings per share from continuing operations is computed by dividing income from continuing operations by the weighted-average number of common shares outstanding during the period. Diluted earnings per share from continuing operations gives effect to all dilutive common shares potentially outstanding during a period. A reconciliation of “Income from continuing operations” and basic and diluted share amounts is as follows (in thousands):

(10)	CHANGES IN COMMON STOCK

Other than the following transactions, the Company has no other material changes in its common stock, as reported in Note 10 of the Company’s 2004 Annual Report on Form 10-K.

• Effective January 1, 2005, the Company adopted a performance share award plan in which certain officers of the Company are participants. Performance shares are awarded on the Company’s total shareholder return over designated performance periods as measured against a selected peer group. In addition, the Company’s stock price must also increase during the performance periods. Target grants of 41,499 performance shares were made for the following performance period January 1, 2005 through December 31, 2007.

Participants may earn additional performance shares if the Company’s total shareholder return exceeds the 50^th percentile of the selected peer group. The final value of the performance shares will vary according to the number of shares of common stock that are ultimately granted based upon the actual level of attainment of the performance criteria. The performance awards are paid 50 percent cash and 50 percent common stock.

Grants under this performance share plan are in addition to grants under two other performance share plans awarded March 1, 2004. Compensation expense recognized for all of the performance share awards for the quarter ended March 31, 2005 was $0.3 million.

• During the first quarter of 2005, the Company granted 12,400 stock options at a weighted-average exercise price of $29.63 per share.

• 13,202 stock options were exercised at a weighted-average price of $26.85 per share.

• The Company issued 3,266 shares of common stock from treasury shares under the short-term incentive compensation plan during the first quarter of 2005. Compensation cost related to the award was approximately $0.1 million, which was accrued for in 2004.

• The Company granted 42,913 restricted common shares and 2,594 restricted stock units during the first quarter of 2005. The pre-tax compensation cost related to the awards of restricted stock and restricted stock units of approximately $1.4 million will be recognized over the three-year vesting period.

(11)	CHANGES IN LONG-TERM DEBT

On January 21, 2005, the Company acquired CLF&P from Xcel Energy, Inc. Included in the purchase price of CLF&P was the assumption of $24.6 million in long-term debt consisting of First Mortgage Bonds. The debt consists of $7.0 million of variable rate Industrial Development Revenue Bonds due in 2021, $10.0 million variable rate Industrial Development Revenue Bonds due 2027 and $7.6 million 7.5 percent Bonds due 2024. Substantially all properties of CLF&P are subject to the liens securing the First Mortgage Bonds. Annual maturities on the First Mortgage Bonds for the next five years are $0.2 million a year.

(14)	SUMMARY OF INFORMATION RELATING TO SEGMENTS OF THE COMPANY’S BUSINESS

The Company’s reportable segments are those that are based on the Company’s method of internal reporting, which generally segregates the strategic business groups due to differences in products, services and regulation. As of March 31, 2005, substantially all of the Company’s operations and assets are located within the United States. The Company’s operations are conducted through seven reporting segments that include: Wholesale Energy group consisting of the following segments: Coal mining, which engages in the mining and sale of coal from its mine near Gillette, Wyoming; Oil and gas, which produces, explores and operates oil and gas interests located in the Rocky Mountain region, Texas, California and other states; Energy marketing and transportation, which markets natural gas, oil and related services to customers in the Midwest, Southwest, Rocky Mountain, West Coast and Northwest regions and transports crude oil in Texas; and Power generation, which produces and sells power and capacity to wholesale customers; and Retail Services group consisting of the following segments: Electric utility, which supplies electric utility service to western South Dakota, northeastern Wyoming and southeastern Montana; Electric and gas utility, acquired January 21, 2005, which supplies electric and gas utility service to Cheyenne, Wyoming and vicinity; and Communications, which primarily markets broadband communications services in Rapid City and the northern Black Hills region of South Dakota. The Company entered into an agreement on April 20, 2005 to sell Black Hills FiberSystems, Inc., which is reported as the Communications segment (see Note 19).

Segment information follows the same accounting policies as described in Note 23 of the Company’s 2004 Annual Report on Form 10-K. In accordance with the provisions of SFAS No. 71 “Accounting for the Effects of Certain Types of Regulation” (SFAS 71), intercompany fuel sales to the electric utility are not eliminated.

Derivatives and certain natural gas marketing activities were marked to fair value on March 31, 2005, December 31, 2004 and March 31, 2004, and the related gains and/or losses recognized in earnings. The amounts included in the accompanying Condensed Consolidated Balance Sheets and Statements of Income are as follows (in thousands):

	Current		Non-current		Current		Non-current
	Derivative		Derivative		Derivative		Derivative		Unrealized
	Assets		Assets		Liabilities		Liabilities		Gain (loss)

In addition, certain volumes of natural gas inventory have been designated as the underlying hedged item in a “fair value” hedge transaction. These volumes are stated at market value using published spot industry quotations. Market adjustments are recorded in inventory on the Balance Sheet and the related unrealized gain/loss on the Statement of Income. As of March 31, 2005, December 31, 2004 and March 31, 2004, the market adjustments recorded in inventory were $4.8 million, $(9.0) million and $0.2 million, respectively.

Activities Other Than Trading

Crude Oil Marketing

The contract or notional amounts and terms of our crude oil contracts, are set forth below (in thousands of barrels):

	March 31, 2005		December 31, 2004		March 31, 2004
		Maximum		Maximum		Maximum
	Notional	Term in	Notional	Term in	Notional	Term in
	Amounts	Years	Amounts	Years	Amounts	Years

Crude oil purchased	1,742	.75	1,669	1.0	1,574	.75
Crude oil sold	1,738	.75	1,651	1.0	2,215	.75

The Company’s crude oil marketing contracts are accounted for under the accrual method of accounting. Settled contract amounts are reported in revenues on a gross basis in accordance with EITF Issue No. 99-19, “Reporting Revenue Gross as a Principal Versus Net as an Agent” (EITF 99-19) and established industry practice.

In 2004, the EITF initiated a review under EITF Issue No. 04-13, “Accounting for Purchases and Sales of Inventory with the Same Counterparty,” to determine if they should be reported on a gross basis or a net basis. In its crude oil marketing activities, the Company uses a type of transaction commonly called a buy/sell, which generally consists of the purchase and sale of crude oil from the same counterparty. In a typical buy/sell transaction, Company A enters into a contract to sell a particular grade of crude oil at a specified location to Company B on a future date, and simultaneously agrees to buy from Company B a particular grade of crude oil at a different location at the same or another specified date.

The characteristics of buy/sell transactions include gross invoicing reflecting the quality and location differences of the crude oil and physical delivery requirements. Nonperformance by one party does not relieve the other party’s obligation to perform under the contract except for events of force majeure. The risks and rewards of ownership are evidenced by title transfer, assumption of environmental risk, transportation scheduling and counterparty credit risk. Because of these characteristics, the Company reports the sale of the barrels as gross revenues and the purchase of the barrels as gross purchases in accordance with EITF 99-19.

Some registrants in our industry may report buy/sell transactions on a net rather than a gross presentation. The EITF is reviewing these transactions to determine if more specific guidance is needed for determining a net rather than gross presentation in consolidated earnings. While a net presentation of this issue would reduce both the Company’s revenues and purchases, our net income would not be impacted.

Oil and Gas Exploration and Production

On March 31, 2005, December 31, 2004 and March 31, 2004, the Company had the following swaps and related balances (in thousands):

(17)	ACQUISITION

On January 13, 2004, the Company entered into a Stock Purchase Agreement to acquire from Xcel Energy, Inc. all of the outstanding capital stock of its subsidiary, CLF&P, a Wyoming corporation. On January 21, 2005, the Company completed this acquisition. The Company purchased all the common stock of CLF&P, including the assumption of outstanding debt of approximately $24.6 million, for approximately $93 million.

This acquisition has been accounted for under the purchase method of accounting, and accordingly, the purchase price has been allocated to the acquired assets and liabilities based on preliminary estimates of the fair values of the assets purchased and liabilities assumed as of the date of acquisition. The estimated purchase price allocations are subject to adjustment, generally within one year of the date of acquisition. Preliminary allocation of the purchase price is as follows (in thousands):

ITEM 2.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

We are a diversified energy holding company operating principally in the United States with two major business groups – wholesale energy and retail services. We report our business groups in the following segments:

Business Group	Financial Segment

Wholesale energy group	Power generation
	Oil and gas
	Coal mining
	Energy marketing and transportation
Retail services group	Electric utility
	Electric and gas utility
	Communications

Our wholesale energy group, Black Hills Energy, Inc., engages in the production of electric power through ownership of a diversified portfolio of generating plants and the sale of electric power and capacity primarily under long-term contracts, the production of coal, natural gas and crude oil primarily in the Rocky Mountain region, and the marketing and transportation of fuel products. Our retail services group consists of our electric and gas utilities and communications segments. Our electric utility generates, transmits and distributes electricity to an average of approximately 62,000 customers in South Dakota, Wyoming and Montana. Our electric and gas utility serves approximately 38,000 electric and 31,000 natural gas customers in Cheyenne, Wyoming and vicinity. Our communications segment primarily provides broadband communications services to over 27,000 residential and business customers in Rapid City and the northern Black Hills region of South Dakota through Black Hills FiberCom, LLC.

In April 2005, we entered into a definitive agreement to sell our subsidiary, Black Hills FiberSystems, Inc., reported as our Communications segment, which primarily markets broadband communications services and which holds two telephone directory businesses. To conform with Generally Accepted Accounting Principles, results of operations for the Communications segment will be reclassified to Discontinued Operations in the second quarter of 2005.

In April 2005, we also sold our Pepperell power plant, our last power plant in the eastern region.

In May 2004, we sold our subsidiary, Landrica Development Corp., which held some land and coal enhancement facilities that were previously reported in our Coal mining segment.

The following discussion should be read in conjunction with Item 7. – Management’s Discussion and Analysis of Financial Condition and Results of Operations – included in our 2004 Annual Report on Form 10-K filed with the Securities and Exchange Commission.

Results of Operations

Consolidated Results

Revenue and Income (loss) from continuing operations provided by each business group as a percentage of our total revenue and total income (loss) from continuing operations were as follows:

	Three Months Ended
	March 31
	2005	2004

Revenues

Wholesale energy	74%	82%
Retail services	26	18
	100%	100%

Income/(Loss) from Continuing Operations

Wholesale energy	84%	73%
Retail services	24	33
Corporate	(8)	(6)
	100%	100%

Discontinued operations in 2005 and 2004 represent the operations of our 40 megawatt Pepperell power plant, which was sold in April, 2005 and in 2004, represents the operations of Landrica Development Corp., which was sold on May 21, 2004.

Three Months Ended March 31, 2005 Compared to Three Months Ended March 31, 2004. On January 21, 2005, we completed the acquisition of CLF&P, an electric and natural gas utility serving customers in Cheyenne, Wyoming and vicinity. The Company purchased all of the common stock of CLF&P, including the assumption of outstanding debt of approximately $24.6 million, for approximately $93 million. The results of operations of CLF&P have been included in the accompanying Condensed Consolidated Financial Statements from the date of acquisition.

Revenues for the three months ended March 31, 2005 increased 11 percent or $31.4 million compared to the same period in 2004. Increased revenues are primarily the result of the acquisition and consolidation of CLF&P.

Operating expenses increased 10 percent, or $24.6 million resulting from an increase in fuel and purchased power costs primarily due to the operations of CLF&P and increased administrative and general costs due to increased compensation expense and professional fees. In addition, a $1.0 million pre-tax gain on the sale of assets was recorded as an offset to general and administrative expense in the first quarter of 2004. The gain on sale of assets is included in the 2004 “Corporate” results.

Income from continuing operations increased 59 percent or $5.9 million due to the increased revenues, and a decrease in interest expense due to a reduction in debt, exclusive of the assumption of the CLF&P debt, offset by increased fuel and purchased power and administrative and general costs.

A discussion of results from our operating groups and segments is included in the following pages.

The following business group and segment information does not include discontinued operations or intercompany eliminations. Accordingly, 2004 information has been revised as necessary to remove information related to operations that were discontinued.

All periods presented reflect a net presentation of revenues at our gas marketing subsidiary and a gross presentation of revenues at our crude oil marketing and transportation subsidiary in accordance with EITF Issue No. 02-3 “Accounting for Contracts Involving Energy Trading and Risk Management Activities” (EITF 02-3) and EITF Issue No. 99-19 “Reporting Revenue Gross as a Principal versus Net as an Agent” (EITF 99-19).

The following is a summary of average daily energy marketing volumes:

	Three Months Ended
	March 31
	2005	2004

Natural gas physical sales – MMbtus	1,357,600	1,201,000
Natural gas financial sales - MMbtus	674,800	383,200
Crude oil – barrels	35,500	49,700

Three Months Ended March 31, 2005 Compared to Three Months Ended March 31, 2004. The decrease in revenues is primarily the result of a 29 percent decrease in crude oil volumes marketed, partially offset by a 42 percent increase in the average price per barrel marketed. Revenue decreases from crude oil marketing were more than offset by a decrease in the cost of crude oil sold resulting in increased crude oil marketing margins.

Income from continuing operations decreased $1.0 million due to a $3.1 million unrealized mark-to-market loss for the quarter ended March 31, 2005, compared to a $0.3 million unrealized loss in the first quarter of 2004, resulting in a quarter-over-quarter, pre-tax decrease of $2.8 million in unrealized mark-to-market adjustment at our gas marketing operations (for discussion of potential volatility in energy marketing earnings related to accounting treatment of certain hedging activities at our natural gas marketing operations see “Trading Activities” in Part 1, Item 3 of this Form 10-Q). These items were partially offset by a $1.7 million increase in realized gas marketing margins received and a 13 percent increase in natural gas physical volumes marketed.

Three Months Ended March 31, 2005 Compared to Three Months Ended March 31, 2004. Revenue increased 9 percent in the first quarter of 2005 compared to the first quarter of 2004 primarily as a result of a $2.4 million increase in revenues at our Las Vegas facility. In the first three months of 2005, our Las Vegas II facility sold capacity and energy to Nevada Power Company under a long-term tolling arrangement, which became effective April 1, 2004, as opposed to selling power into the market on a merchant basis, for the same period in 2004, when economic to do so.

Income from continuing operations increased $6.0 million. Increased earnings were the result of higher revenues, decreased fuel cost primarily related to generating costs at our Las Vegas facility, and lower interest expense from debt reduction and increased income from equity investments.

Three Months Ended March 31, 2005 Compared to Three Months Ended March 31, 2004. Income from continuing operations for the first quarter of 2005 increased $1.3 million over the comparable period in 2004. Volumes sold increased 13 percent, primarily related to increased production. Average gas and oil prices received, net of hedges, in the first three months of 2005 were $5.36/Mcf and $32.73/bbl, respectively, compared to $5.15/Mcf and $26.87/bbl in the first three months of 2004. Total operating expenses increased 9 percent primarily due to increased production expenses related to the additional sales volumes. The 2005 lease operating expenses per Mcf sold (LOE/MCF) decreased 16 percent from $0.99/Mcf in 2004 to $0.83/Mcf in 2005 due to production efficiencies realized from an increase in productive wells placed in service.

The following is a summary of our internally estimated, economically recoverable oil and gas reserves. These estimates are measured using constant product prices. The increases in reserves are primarily the result of increased product prices. Estimates of economically recoverable reserves for interim periods are based on independent year-end reserve studies updated for acquisitions, drilling activity, property sales and actual production during the interim period. These internally estimated reserves may differ from actual results.

Three Months Ended March 31, 2005 Compared to Three Months Ended March 31, 2004. Revenue from our coal mining segment decreased 8 percent for the three-month period ended March 31, 2005, compared to the same period in 2004. The decrease in revenue was primarily attributable to unscheduled outages at the Wyodak plant. The Wyodak plant, operated by our joint interest partner (PacifiCorp), has postponed a planned 2005 major maintenance outage and rescheduled the outage for 2006.

Operating expenses decreased 7 percent or approximately $0.4 million, primarily due to lower depletion rates and lower mineral tax expense, related to the decrease in revenues.

Income from continuing operations decreased 15 percent due to the decrease in revenues partially offset by lower taxes and production-related costs.

Three Months Ended March 31, 2005 Compared to Three Months Ended March 31, 2004. Electric utility revenues increased 4 percent for the three-month period ended March 31, 2005, compared to the same period in the prior year. The increase in revenue was primarily due to a 14 percent increase in off-system electric megawatt-hour sales at an 8 percent increase in average prices received. Firm residential, commercial and wholesale sales increased 1 percent, 2 percent and 1 percent, respectively, and industrial sales declined 1 percent. Degree days, which is a measure of weather trends, were 4 percent below last year.

Electric operating expenses increased 11 percent for the three-month period ended March 31, 2005, compared to the same period in the prior year. Purchased power increased $2.7 million due to a 14 percent increase in megawatt-hours purchased, at a 13 percent increase in the average cost per megawatt-hour. The increase in purchased power costs was primarily due to the increased off-system sales and 18 days of unscheduled plant outages at the Wyodak plant and was partially offset by a $0.3 million decrease in fuel costs as prevailing gas prices made it more economical for us to purchase power for our peaking needs and increased off-system sales, rather than generate energy utilizing our gas turbines. The Wyodak plant has postponed a planned 2005 maintenance outage and rescheduled the maintenance outage for 2006. The increase in operating expense was also affected by increased legal expense and health insurance costs, partially offset by lower maintenance costs.

Income from continuing operations decreased $0.7 million primarily due to the increase in purchased power expense, legal expense and health insurance expense, partially offset by an increase in electric sales and a decrease in interest expense primarily due to the pay down of debt.

Natural gas sales comprised 41 percent or $11.0 million of total revenues, and electric sales comprised 59 percent or $16.1 million of total revenues for this segment.

On April 18, 2005, applications were filed with the Wyoming Public Service Commission (WPSC) to increase the base rates for retail electric and natural gas service effective January 1, 2006. The applications request a 3.94 percent and 5.62 percent increase in electric and gas revenues, respectively. We expect that these increases, if approved by the WPSC, would result in an annual revenue increase of approximately $5.2 million.

Three Months Ended March 31, 2005 Compared to Three Months Ended March 31, 2004. The communications business group’s net loss was $0.9 million for the three-month period ended March 31, 2005 compared to a net loss of $1.8 million for the same period in 2004. Revenues increased 14 percent as a result of a 2 percent increase in customers and the expiration of a sales incentive marketing campaign initiated in response to a local competitor’s aggressive pricing pressure in 2004. Revenue was also impacted by a 4 percent increase in residential revenue generating units over the same period in the prior year. The increase in revenues was partially offset by an increase in the cost of sales related to the increase in customers.

In April 2005, we entered into a definitive agreement to sell our communications business. Under the purchase and sale agreement, we will receive a cash payment of approximately $103 million. The transaction is subject to certain state and federal regulatory approvals and is expected to be completed prior to June 30, 2005. We expect to record a loss of approximately $0.09 per share on the sale.

Critical Accounting Policies

There have been no material changes in our critical accounting policies from those reported in our 2004 Annual Report on Form 10-K filed with the Securities and Exchange Commission. For more information on our critical accounting policies, see Part II, Item 7 of our 2004 Annual Report on Form 10-K.

Liquidity and Capital Resources

Cash Flow Activities

During the three-month period ended March 31, 2005, we generated sufficient cash flow from operations to meet our operating needs, to pay dividends on common and preferred stock, to pay our long-term debt maturities, and to fund our property, plant and equipment additions and the CLF&P acquisition (exclusive of debt assumed). We plan to fund future property and investment additions primarily through a combination of operating cash flow and increased short-term and long-term debt.

Cash flows from operations increased $24.3 million for the three-month period ended March 31, 2005 compared to the same period in the prior year primarily due to a $6.0 million increase in net income, an $18.7 million increase in our cash flows from net derivative assets and liabilities and a $4.8 million increase in cash flows from distributions from equity investments partially offset by a $7.3 million decrease in operating assets and liabilities.

During the three months ended March 31, 2005, we had cash outflows from investing activities of $97.0 million, which was primarily related to property, plant and equipment additions in the normal course of business and the $67.3 million cash payment related to the acquisition of CLF&P.

During the three months ended March 31, 2005, we had cash outflows from financing activities of $10.3 million, primarily due to the payment of quarterly cash dividends on common stock.

Dividends

Dividends paid on our common stock totaled $10.4 million, or $0.32 per share in the first quarter of 2005. This reflects a 3.2 percent increase, as approved by our board of directors in January 2005, from the 2004 quarterly dividend level. The determination of the amount of future cash dividends, if any, to be declared and paid will depend upon, among other things, our financial condition, funds from operations, the level of our capital expenditures, restrictions under PUHCA, restrictions under our credit facilities and our future business prospects.

Short-Term Liquidity and Financing Transactions

Our principal sources of short-term liquidity are revolving bank facilities and cash provided by operations. Our liquidity position remained strong during the first quarter of 2005. As of March 31, 2005, we had approximately $67.6 million of cash unrestricted for operations and $350 million of credit through revolving bank facilities. Approximately $41.1 million of the cash balance at March 31, 2005 was restricted by subsidiary debt agreements that limit our subsidiaries’ ability to dividend cash to the parent company. The bank facilities consisted of a $225 million facility due August 20, 2006 and a $125 million facility due May 12, 2005.

These bank facilities can be used to fund our working capital needs, for general corporate purposes, and to provide liquidity for a commercial paper program if implemented. At March 31, 2005, we had $25.0 million of borrowings outstanding under these facilities. After inclusion of applicable letters of credit, the remaining borrowing capacity under the bank facilities was $277.4 million at March 31, 2005.

On May 5, 2005, the Company entered into a new $400 million revolving bank facility with ABN AMRO as Administrative Agent, Union Bank of California and US Bank as Co-Syndication Agents, Bank of America and Harris Nesbitt as Co-Documentation Agents, and other syndication participants. The new facility has a five year term, expiring May 4, 2010. The facility contains a provision which allows the facility size to be increased by up to an additional $100 million through the addition of new lenders, or through increased commitments from existing lenders, but only with the consent of such lenders. The cost of borrowings or letters of credit issued under the new facility is determined based on the Company’s credit ratings; at the Company’s current ratings levels, the facility has an annual facility fee of 17.5 basis points, and a borrowing spread of 70.0 basis points over the one month LIBOR (which equates to a 3.57 percent borrowing rate as of March 31, 2005). In conjunction with entering into the new revolving bank facility, the Company terminated its $125 million revolving bank facility due May 12, 2005 and its $225 million facility due August 20, 2006.

The bank facility includes customary affirmative and negative covenants, such as limitations on the creation of new indebtedness and on certain liens, restrictions on certain transactions and maintenance of the following financial covenants:

• a consolidated net worth in an amount of not less than the sum of $625 million and 50 percent of our aggregate consolidated net income beginning January 1, 2005;

• a recourse leverage ratio not to exceed 0.65 to 1.00; and

• an interest coverage ratio of not less than 2.5 to 1.0.

If these covenants are violated, it would be considered an event of default entitling the lender to terminate the remaining commitment and accelerate all principal and interest outstanding.

A default under the bank facility may be triggered by events such as a failure to comply with financial covenants or certain other covenants under the bank facility, a failure to make payments when due or a failure to make payments when due in respect of, or a failure to perform obligations relating to, debt obligations of $20 million or more. A default under the bank facility would permit the participating banks to restrict the Company’s ability to further access the credit facility for loans or new letters of credit, require the immediate repayment of any outstanding loans with interest and require the cash collateralization of outstanding letter of credit obligations.

The bank facility prohibits the Company from paying cash dividends unless no default or no event of default exists prior to, or would result after, giving effect to such action.

Our consolidated net worth was $737.7 million at March 31, 2005, which was approximately $155.7 million in excess of the net worth we were required to maintain under the bank facilities in place at March 31, 2005. The long-term debt component of our capital structure at March 31, 2005 was 50.6 percent, our total debt leverage (long-term debt and short-term debt) was 52.0 percent, and our recourse leverage ratio was approximately 47.4 percent.

In addition, Enserco Energy Inc., our gas marketing unit, has a $150 million uncommitted, discretionary line of credit to provide support for the purchase of natural gas. As of March 31, 2005, we had a $3.0 million guarantee to the lender under this facility. At March 31, 2005, there were outstanding letters of credit issued under the facility of $99.8 million, with no borrowing balances outstanding on the facility.

Similarly, Black Hills Energy Resources, Inc., (BHER), our oil marketing unit, has a $25 million uncommitted, discretionary credit facility. The facility allows BHER to elect up to $40 million of available credit via notification to the bank at the beginning of each calendar quarter. This line of credit provides credit support for the purchases of crude oil by BHER. We provided no guarantee to the lender under this facility. At March 31, 2005, BHER had letters of credit outstanding of $17.7 million.

There were no changes in our corporate credit ratings during the first quarter of 2005.

Our ability to obtain additional financing, if necessary, will depend upon a number of factors, including our future performance and financial results, and capital market conditions. We can provide no assurance that we will be able to raise additional capital on reasonable terms or at all.

Upon closing of the agreement to sell our communications subsidiary, Black Hills FiberSystems, Inc., we expect to receive a cash payment of approximately $103 million. The transaction is expected to be completed on or before June 30, 2005. Proceeds from the transaction are expected to be used to reduce debt, to fund our capital expenditures or a combination of both.

There have been no other material changes in our forecasted changes in liquidity requirements from those reported in Item 7 of our 2004 Annual Report on Form 10-K filed with the Securities and Exchange Commission.

Guarantees

During the first quarter of 2005, a $0.5 million guarantee related to payments under various transactions with Idaho Power Company was reduced to $0.3 million. At March 31, 2005, we had guarantees totaling $183.5 million in place.

Capital Requirements

During the three months ended March 31, 2005, capital expenditures were approximately $28.3 million for property, plant and equipment additions and $67.3 million for the acquisition of CLF&P (exclusive of debt assumed). We currently expect capital expenditures for the entire year 2005 to approximate $245 million, as detailed in Item 7 of our 2004 Annual Report on Form 10-K filed with the Securities and Exchange Commission.

RISK FACTORS

Other than as set forth below, there have been no material changes in our Risk Factors from those reported in Items 1 and 2 of our 2004 Annual Report on 10-K filed with the Securities and Exchange Commission, which we incorporate by reference herein.

Our sale of Black Hills FiberSystems, Inc. is subject to the receipt of approvals and consents from governmental authorities and third parties. If we do not complete the acquisition, we may continue to incur losses in our Communications segment.

On April 20, 2005, we entered into an agreement with PrairieWave Communications, Inc. for PrairieWave to acquire all the outstanding common stock of Black Hills FiberSystems, Inc. for approximately $103.0 million in cash. Completion of the sale is conditioned, among other things, upon the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, consent by the SDPUC and the receipt of consents, orders, approvals or clearance of certain other regulatory authorities and third parties. A failure to obtain satisfactory approvals, a substantial delay thereof or the imposition of unfavorable terms or conditions in the approvals could prevent us from consummating the sale and could cause us to continue to incur losses from our Communications segment, and could have other adverse effects on our business, financial condition or results of operation.

Our utilities may not raise their retail rates without prior approval of the South Dakota Public Utilities Commission or the Wyoming Public Services Commission. Any delays in obtaining approvals or having cost recovery disallowed in such rate proceedings could have an adverse effect on our revenues and results of operation.

The rate freeze agreement with the SDPUC for our Black Hills Power electric utility expired on January 1, 2005. Until such time as we petition the SDPUC or the WPSC for rate relief, or either commission requires that we do so, Black Hills Power may not increase its retail rates. Additionally, Black Hills Power may not invoke any fuel and purchased power adjustment tariff that would take effect prior to the completion of a rate proceeding, absent extraordinary circumstances. Because our utilities are generally unable to increase their base rates without prior approval from the SDPUC and the WPSC, our returns could be threatened by plant outages, machinery failure, increases in purchased power costs over which our utilities have no control, acts of nature, acts of terrorism or other unexpected events that could cause operating costs to increase and operating margins to decline. Moreover, in the event of unexpected plant outages or machinery failures, Black Hills Power may be required to purchase replacement power in wholesale power markets at prices that exceed the rates it is permitted to charge its retail customers. Finally, our utilities’ costs would be subject to the review of the SDPUC or the WPSC, and the commissions could find certain costs not to be recoverable, thus negatively affecting our revenues and results of operation.

As part of the process for obtaining approval to acquire CLF&P, we agreed with the WPSC that CLF&P and Black Hills Power would not raise retail rates for their respective Wyoming customers prior to January 1, 2006. In anticipation of such date, our CLF&P utility filed rate cases with the WPSC on April 18, 2005 with respect to its retail gas and electric rates, requesting 5.62% and 3.94% increases in such rates, respectively. In the rate cases, the WPSC will establish, among other things, the return on common equity, overall rate of return, depreciation expenses and cost of capital for CLF&P. Any costs found by the WPSC that have not been prudently incurred would not be recoverable from CLF&P’s customers. Such a finding, among any other unfavorable rulings by the WPSC in these rate cases, could negatively affect our revenues and results of operation.

NEW ACCOUNTING PRONOUNCEMENTS

Other than the new pronouncements reported in our 2004 Annual Report on Form 10-K filed with the Securities and Exchange Commission and those discussed in Note 4 of the Notes to Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q, there have been no new accounting pronouncements issued that when implemented would require us to either retroactively restate prior period financial statements or record a cumulative catch-up adjustment.

SAFE HARBOR FOR FORWARD-LOOKING INFORMATION

This Quarterly Report on Form 10-Q includes “forward-looking statements” as defined by the Securities and Exchange Commission, or SEC. We make these forward-looking statements in reliance on the safe harbor protections provided under the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical facts, included in this Form 10-Q that address activities, events or developments that we expect, believe or anticipate will or may occur in the future are forward-looking statements. These forward-looking statements are based on assumptions which we believe are reasonable based on current expectations and projections about future events and industry conditions and trends affecting our business. However, whether actual results and developments will conform to our expectations and predictions is subject to a number of risks and uncertainties that, among other things, could cause actual results to differ materially from those contained in the forward-looking statements, including the risk factors described in Items 1 and 2 of our 2004 Annual Report on Form 10-K filed with the SEC, and the following:

• The amount and timing of capital deployment in new investment opportunities or for the repurchase of debt or stock;

• The volumes of our production from oil and gas development properties, which may be dependent upon issuance by federal, state, and tribal governments, or agencies thereof, of drilling, environmental and other permits, and the availability of specialized contractors, work force, and equipment;

• Our ability to complete the sale of Black Hills FiberSystems, Inc., including the receipt of required approvals and consents and the timing thereof;

• Our ability to remedy any deficiencies that may be identified in the periodic review of our internal controls;

• The timing and extent of changes in energy-related and commodity prices, interest rates, energy and commodity supply or volume, the cost of transportation of commodities, and demand for our services, all of which can affect our earnings, liquidity position and the underlying value of our assets;

• The timing and extent of scheduled and unscheduled outages of power generation facilities;

• General economic and political conditions, including tax rates or policies and inflation rates;

• Our use of derivative financial instruments to hedge commodity, currency exchange rate and interest rate risks;

• The creditworthiness of counterparties to trading and other transactions, and defaults on amounts due from counterparties;

• The amount of collateral required to be posted from time to time in our transactions;

• Changes in or compliance with laws and regulations, particularly those relating to taxation, safety and protection of the environment;

• Changes in state laws or regulations that could cause us to curtail our independent power production;

• Weather and other natural phenomena;

• Industry and market changes, including the impact of consolidations and changes in competition;

• The effect of accounting policies issued periodically by accounting standard-setting bodies;

• The cost and effects on our business, including insurance, resulting from terrorist actions or responses to such actions;

• Capital market conditions, which may affect our ability to raise capital on favorable terms;

• Price risk due to marketable securities held as investments in benefit plans;

• Obtaining adequate cost recovery for our retail operations through regulatory proceedings; and

• Other factors discussed from time to time in our other filings with the SEC.

New factors that could cause actual results to differ materially from those described in forward-looking statements emerge from time to time, and it is not possible for us to predict all such factors, or the extent to which any such factor or combination of factors may cause actual results to differ from those contained in any forward-looking statement. We assume no obligation to update publicly any such forward-looking statements, whether as a result of new information, future events, or otherwise.

On January 1, 2003, the Company adopted EITF 02-3. The adoption of EITF 02-3 resulted in certain energy trading activities no longer being accounted for at fair value, therefore, the above reconciliation does not present a complete picture of our overall portfolio of trading activities and our expected cash flows from those operations. EITF Issue No. 98-10 “Accounting for Contracts Involved in Energy Trading and Risk Management Activities” (EITF 98-10) was superseded by EITF 02-3 and allowed a broad interpretation of what constituted “trading activity” and hence what would be marked-to-market. EITF 02-3 took a much narrower view of what “trading activity” should be marked-to-market, limiting mark-to-market treatment primarily to only those contracts that meet the definition of a derivative under SFAS No. 133 “Accounting for Derivative Instruments and Hedging Activities” (SFAS 133). At our natural gas marketing operations, we often employ strategies that include derivative contracts along with inventory, storage and transportation positions to accomplish the objectives of our producer services, end-use origination and wholesale marketing groups. Except in very limited circumstances when we are able to designate transportation, storage or inventory positions as part of a fair value hedge, SFAS 133 generally does not allow us to mark our inventory, transportation or storage positions to market. The result is that while a significant majority of our natural gas marketing positions are fully economically hedged, we are required to mark some parts of our overall strategies (the derivatives) to market value, but are generally precluded from marking the rest of our economic hedges (transportation, inventory or storage) to market. Volatility in reported earnings and derivative positions should be expected given these accounting requirements.

At March 31, 2005, we had a mark to fair value unrealized loss of $(4.6) million for our natural gas marketing activities, with $(4.3) million of this amount current. The sources of fair value measurements were as follows (in thousands):

	Maturities
Source of Fair Value	Less than 1 year		1 – 2 years		Total Fair Value

Actively quoted (i.e., exchange-traded) prices	$	2,067	$	157	$	2,224
Prices provided by other external sources		(6,391)		(431)		(6,822)
Modeled		—		—		—

Total	$	(4,324)	$	(274)	$	(4,598)

The following table presents a reconciliation of our March 31, 2005 natural gas marketing positions recorded at fair value under generally accepted accounting principles (GAAP) to a non-GAAP measure of the fair value of our natural gas forward book wherein all forward trading positions are marked-to-market (in thousands). The approach used in determining the non-GAAP measure is consistent with our previous accounting methods under EITF 98-10. As part of our GAAP fair value calculations we include a “Liquidity Reserve” to reflect a liquidation scenario on the balance sheet date. We have added back this liquidity reserve in the non-GAAP presentation below as we anticipate holding our natural gas contracts until their settlement and therefore not incur the impact of the bid/ask spread in our realized gross margin.

Increase in fair value of inventory, storage and transportation positions that are
part of our forward trading book, but that are not marked-to-market under GAAP		4,359

Fair value of all forward positions (Non-GAAP)		(239)

“Liquidity Reserve” included in GAAP marked-to-market fair value (b)		2,723

Fair value of all forward positions excluding the “Liquidity Reserve” (Non-GAAP)	$	2,484

(b)

In accordance with generally accepted accounting principles and industry practice, the Company includes a “Liquidity Reserve” in its GAAP marked-to-market fair value. This “Liquidity Reserve” accounts for the estimated impact of the bid/ask spread in a liquidation scenario under which the Company is forced to liquidate its forward book on the balance sheet date.

There have been no material changes in market risk faced by us from those reported in our 2004 Annual Report on Form 10-K filed with the Securities and Exchange Commission. For more information on market risk, see Part II, Item 7 in our 2004 Annual Report on Form 10-K, and Note 15 of our Notes to Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q.

ITEM 4.

CONTROLS AND PROCEDURES

Our Chief Executive Officer and Chief Financial Officer evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (Exchange Act)) as of March 31, 2005. Based on their evaluation, they have concluded that our disclosure controls and procedures are adequate and effective to ensure that material information relating to us that is required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized and reported within the required time periods.

On January 21, 2005, we acquired Cheyenne Light, Fuel and Power (CLF&P). We have not been able to complete an assessment of CLF&P’s internal control over financial reporting between the acquisition date and the end of this reporting period. The Securities and Exchange Commission allows companies one year after acquisition to complete their assessment.

Since the acquisition of CLF&P, we have been focusing on integrating it into our company. We have and will continue to analyze and implement changes in CLF&P’s procedures and controls to ensure their effectiveness.

Other than changes resulting from our acquisition of CLF&P, there have been no changes in our internal control over financial reporting that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

Subject to Section 2.2(b) hereof, the obligation of Borrower to reimburse the applicable Issuing Agent for all drawings under a Letter of Credit (a “Reimbursement Obligation”) shall be governed, to the extent not inconsistent with this Agreement, by the Master Letter of Credit Agreement and the Application related to such Letter of Credit, except that reimbursement of each drawing shall be made in immediately available funds at the applicable Issuing Agent’s principal office in New York, New York by no later than 1:30 p.m. (New York time) on the date when such drawing is paid or, if such drawing was paid after 1:30 p.m. (New York time), by the end of such day. If Borrower does not make any such reimbursement payment on the date due (whether through a deemed request for a Base Rate Loan pursuant to Section 2.5(c) or otherwise) and the Banks fund their participations therein in the manner set

60364071.5

forth in Section 2.2(d) below, then all payments thereafter received by an Issuing Agent in discharge of any of the relevant Reimbursement Obligations shall be distributed in accordance with Section 2.2(d) below. An Issuing Agent shall notify Borrower promptly of its intent to pay, or payment of, a drawing under a Letter of Credit.

(d) The Participating Interests. Each Bank, by its acceptance hereof, severally agrees to purchase from each Issuing Agent, and each Issuing Agent hereby agrees to sell to each such Bank, an undivided percentage participating interest (a “Participating Interest”), to the extent of its Percentage, in each Letter of Credit issued by, and each Reimbursement Obligation owed to, such Issuing Agent. Upon any failure by Borrower to pay any Reimbursement Obligation at the time required on the date the related drawing is paid, as set forth in Section 2.2(c) above, or if an Issuing Agent is required at any time to return to Borrower or to a trustee, receiver, liquidator, custodian or other Person any portion of any payment of any Reimbursement Obligation, each Bank shall, not later than the Business Day it receives a demand from such Issuing Agent to such effect, if such demand is received before 2:00 p.m. (New York time), or not later than the following Business Day, if such demand is received after such time, pay to such Issuing Agent an amount equal to its Percentage of such unpaid or recaptured Reimbursement Obligation together with interest on such amount accrued from the date the related payment was made by such Issuing Agent to the date of such payment by such Bank a rate per annum equal to (i) from the date the related payment was made by such Issuing Agent to the date two (2) Business Days after payment by such Bank is due hereunder, the Federal Funds Rate for each such day and (ii) from the date two (2) Business Days after the date such payment is due from such Bank to the date such payment is made by such Bank, the Base Rate in effect for each such day. Each such Bank shall thereafter be entitled to receive its Percentage of each payment received in respect of the relevant Reimbursement Obligation and of interest paid thereon, with the applicable Issuing Agent retaining its Percentage as a Bank hereunder.

The several obligations of the Banks to the Issuing Agents under this Section 2.2 shall be absolute, irrevocable and unconditional under any and all circumstances whatsoever and shall not be subject to any set-off, counterclaim or defense to payment which any Bank may have or have had against Borrower, the Administrative Agent, the Issuing Agents, any Bank or any other Person whatsoever. Without limiting the generality of the foregoing, such obligations shall not be affected by any Default or Event of Default or by any reduction or termination of any Commitment of any Bank, and each payment by a Bank under this Section 2.2 shall be made without any offset, abatement, withholding or reduction whatsoever. The Issuing Agents and the Administrative Agent shall be entitled to offset amounts received for the account of a Bank under the Credit Documents against unpaid amounts due from such Bank to the applicable Issuing Agent or the Administrative Agent, as applicable, hereunder (whether as fundings of participations, indemnities or otherwise).

(e) Indemnification. The Banks shall, to the extent of their respective Percentages, indemnify each Issuing Agent (to the extent not reimbursed by Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such Issuing Agent’s gross negligence or willful misconduct) that an Issuing Agent may suffer or incur in connection

60364071.5

with any Letter of Credit issued by it. The Issuing Agents shall be entitled to all of the rights and protections afforded the Administrative Agent under Section 10 hereof. The obligations of the Banks under this Section 2.2(e) and all other parts of this Section 2.2 shall survive termination of this Agreement and of all other L/C Documents.

(f) Issuing Agents. Each Bank hereby appoints U.S. Bank, National Association, and any other Person who satisfies the definition of Issuing Agent, as the Issuing Agents hereunder and hereby authorizes each of the Issuing Agent to take such action as Issuing Agent on its behalf and to exercise such powers under the Credit Documents as are delegated to the Issuing Agents by the terms thereof, together with such powers as are reasonably incidental thereto. The relationship between each of the Issuing Agents and the Banks is and shall be that of agent and principal only, and nothing contained in this Agreement or any other Credit Document shall be construed to constitute a Issuing Agent as a trustee or fiduciary for any Bank or the Borrower.

Section 2.3 Applicable Interest Rates. (a) Base Rate Loans. Each Base Rate Loan made or maintained by a Bank shall bear interest during each Interest Period it is outstanding (computed (x) at all times the Base Rate is based on the rate described in clause (i) of the definition thereof, on the basis of a year of 365 or 366 days, as applicable, and actual days elapsed or (y) at all times the Base Rate is based on the rate described in clause (ii) of the definition thereof, on the basis of a year of 360 days and actual days elapsed) on the unpaid principal amount thereof from the date such Loan is advanced, continued or created by conversion from a Eurodollar Loan until maturity (whether by acceleration or otherwise) at a rate per annum equal to the sum of the Applicable Margin plus the Base Rate from time to time in effect, payable on the last day of its Interest Period and at maturity (whether by acceleration or otherwise).

“Base Rate” means for any day the greater of:

(i) the rate of interest announced by ABN AMRO Bank N.V. from time to time as its prime rate, or equivalent, for U.S. Dollar loans within the United States as in effect on such day, with any change in the Base Rate resulting from a change in said prime rate to be effective as of the date of the relevant change in said prime rate; and

(ii) the sum of (x) the Federal Funds Rate, plus (y) one half of one percent (0.50%).

(b) Eurodollar Loans. Each Eurodollar Loan made or maintained by a Bank shall bear interest during each Interest Period it is outstanding (computed on the basis of a year of 360 days and actual days elapsed) on the unpaid principal amount thereof from the date such Loan is advanced, continued, or created by conversion from a Base Rate Loan until maturity (whether by acceleration or otherwise) at a rate per annum equal to the sum of the Applicable Margin plus the Adjusted LIBOR applicable for such Interest Period, payable on the last day of the Interest Period and at maturity (whether by acceleration or otherwise), and, if the applicable Interest Period is longer than three

60364071.5

months, on each day occurring every three months after the commencement of such Interest Period.

“Adjusted LIBOR” means, for any Borrowing of Eurodollar Loans, a rate per annum determined in accordance with the following formula:

Adjusted LIBOR =

LIBOR

1 - Eurodollar Reserve Percentage

“LIBOR” means, for an Interest Period for a Borrowing of Eurodollar Loans, (a) the LIBOR Index Rate for such Interest Period, if such rate is available, and (b) if the LIBOR Index Rate cannot be determined, the arithmetical average of the rates of interest per annum (rounded upwards, if necessary, to the nearest one-sixteenth of one percent) at which deposits in U.S. Dollars, in immediately available funds are offered to the Administrative Agent at 11:00 a.m. (London, England time) two (2) Business Days before the beginning of such Interest Period by major banks in the interbank eurodollar market for delivery on the first day of and for a period equal to such Interest Period in an amount equal or comparable to the principal amount of the Eurodollar Loan scheduled to be made by each Bank as part of such Borrowing.

“LIBOR Index Rate” means, for any Interest Period, the rate per annum (rounded upwards, if necessary, to the next higher one-sixteenth of one percent) for deposits in U.S. Dollars for delivery on the first day of and for a period equal to such Interest Period in an amount equal or comparable to the principal amount of the Eurodollar Loan scheduled to be made by each Bank as part of such Borrowing, which appears on the Applicable Telerate Page as of 11:00 a.m. (London, England time) on the day two (2) Business Days before the commencement of such Interest Period.

“Applicable Telerate Page” means the display page designated as “Page 3750” on the Telerate Service (or such other pages as may replace any such page on that service or such other service as may be nominated by the British Bankers’ Association as the information vendor for the purpose of displaying British Bankers’ Association Interest Settlement Rates for deposits in U.S. Dollars).

“Eurodollar Reserve Percentage” means for an Borrowing of Eurodollar Loans from any Bank, the daily average for the applicable Interest Period of the actual effective rate, expressed as a decimal, at which reserves (including, without limitation, any supplemental, marginal and emergency reserves) are maintained by such Bank during such Interest Period pursuant to Regulation D of the Board of Governors of the Federal Reserve System (or any successor) on “eurocurrency liabilities”, as defined in such Board’s Regulation D (or in respect of any other category of liabilities that includes deposits by reference to which the interest rate on Eurodollar Loans is determined or any category of extensions of credit or other assets that include loans by non-United States offices of any Bank to United States residents), subject to any amendments of such reserve requirement by such Board or its successor, taking into account any transitional adjustments thereto. For purposes of this definition, the Eurodollar Loans shall be deemed to be “eurocurrency liabilities” as defined in Regulation D without benefit or credit for any prorations, exemptions or offsets under Regulation D.

60364071.5

(c) Rate Determinations. The Administrative Agent shall determine each interest rate applicable to Obligations, and a determination thereof by the Administrative Agent shall be conclusive and binding except in the case of manifest error.

Section 2.4 Minimum Borrowing Amounts. Each Borrowing of Base Rate Loans and Eurodollar Loans shall be in an amount not less than (i) if such Borrowing is comprised of Borrowing of Base Rate Loans, $1,000,000 and integral multiples of $500,000 in excess thereof, and (ii) if such Borrowing is comprised of Borrowing of Eurodollar Loans, $2,000,000 and integral multiples of $1,000,000 in excess thereof, provided that a Borrowing of Base Rate Loans applied to pay a Reimbursement Obligation pursuant to Section 2.5(c) hereof shall be in an amount equal to such Reimbursement Obligation.

Section 2.5 Manner of Borrowing Loans and Designating Interest Rates Applicable to Loans.

(a) Notice to the Administrative Agent. The Borrower shall give notice to the Administrative Agent by no later than 12:00 noon (New York time) (i) at least three (3) Business Days before the date on which Borrower requests the Banks to advance a Borrowing of Eurodollar Loans, or (ii) on the date on which Borrower requests the Banks to advance a Borrowing of Base Rate Loans. The Loans included in each Borrowing shall bear interest initially at the type of rate specified in such notice of a new Borrowing. Thereafter, Borrower may from time to time elect to change or continue the type of interest rate borne by each Borrowing or, subject to Section 2.4’s minimum amount requirement for each outstanding Borrowing, a portion thereof, as follows: (i) if such Borrowing is of Eurodollar Loans, on the last day of the Interest Period applicable thereto, Borrower may continue part or all of such Borrowing as Eurodollar Loans for an Interest Period or Interest Periods specified by Borrower or convert part or all of such Borrowing into Base Rate Loans, and (ii) if such Borrowing is of Base Rate Loans, on any Business Day, Borrower may convert all or part of such Borrowing into Eurodollar Loans for an Interest Period or Interest Periods specified by Borrower. Borrower shall give all such notices requesting, the advance, continuation, or conversion of a Borrowing to the Administrative Agent by telephone or telecopy (which notice shall be irrevocable once given and, if by telephone, shall be promptly confirmed in writing). Notices of the continuation of a Borrowing of Eurodollar Loans for an additional Interest Period or of the conversion of part or all of a Borrowing of Eurodollar Loans into Base Rate Loans or of Base Rate Loans into Eurodollar Loans must be given by no later than 12:00 noon (New York time) at least three (3) Business Days before the date of the requested continuation or conversion. All such notices concerning the advance, continuation, or conversion of a Borrowing shall be irrevocable once given and shall specify the date of the requested advance, continuation or conversion of a Borrowing (which shall be a Business Day), the amount of the requested Borrowing to be advanced, continued, or converted, the type of Loans to comprise such new, continued or converted Borrowing and, if such Borrowing is to be comprised of Eurodollar Loans, the Interest Period applicable thereto. Borrower agrees that the Administrative Agent may rely on any such telephonic or telecopy notice given by any person it in good faith believes is an Authorized Representative without the necessity of independent investigation, and in the event any such notice by telephone conflicts with any written confirmation, such

60364071.5

telephonic notice shall govern if the Administrative Agent has acted in reliance thereon. There may be no more than six different Interest Periods in effect at any one time, provided that for purposes of determining the number of Interest Periods in effect at any one time, all Base Rate Loans shall be deemed to have one and the same Interest Period.

(b) Notice to the Banks. The Administrative Agent shall give prompt telephonic or telecopy notice to each Bank of any notice from Borrower received pursuant to Section 2.5(a) above. The Administrative Agent shall give notice to Borrower and each Bank by like means of the interest rate applicable to each Borrowing of Eurodollar Loans.

(c) Borrower’s Failure to Notify. Any outstanding Borrowing of Base Rate Loans shall, subject to Section 6.2 hereof, automatically be continued for an additional Interest Period on the last day of its then current Interest Period unless Borrower has notified the Administrative Agent within the period required by Section 2.5(a) that it intends to convert such Borrowing into a Borrowing of Eurodollar Loans or notifies the Administrative Agent within the period required by Section 2.8(a) that it intends to prepay such Borrowing. If Borrower fails to give notice pursuant to Section 2.5(a) above of the continuation or conversion of any outstanding principal amount of a Borrowing of Eurodollar Loans before the last day of its then current Interest Period within the period required by Section 2.5(a) and has not notified the Administrative Agent within the period required by Section 2.8(a) that it intends to prepay such Borrowing, such Borrowing shall automatically be converted into a Borrowing of Base Rate Loans, subject to Section 6.2 hereof. The Administrative Agent shall promptly notify the Banks of Borrower’s failure to so give a notice under Section 2.5(a). In the event Borrower fails to give notice pursuant to Section 2.5(a) above of a Borrowing equal to the amount of a Reimbursement Obligation and has not notified the Administrative Agent by 12:00 noon (New York time) on the day such Reimbursement Obligation becomes due that it intends to repay such Reimbursement Obligation through funds not borrowed under this Agreement, Borrower shall be deemed to have requested a Borrowing of Base Rate Loans on such day in the amount of the Reimbursement Obligation then due, subject to Section 6.2 hereof, which Borrowing shall be applied to pay the Reimbursement Obligation then due.

(d) Disbursement of Loans. Not later than 12:00 noon (New York time) on the date of any requested advance of a new Borrowing of Eurodollar Loans, and not later than 2:00 p.m. (New York time) on the date of any requested advance of a new Borrowing of Base Rate Loans, subject to Section 6 hereof, each Bank shall make available its Loan comprising part of such Borrowing in funds immediately available at the principal office of the Administrative Agent in New York, New York. The Administrative Agent shall make available to Borrower Loans at the Administrative Agent’s principal office in New York, New York or such other office as the Administrative Agent has previously agreed in writing to with Borrower, in each case in the type of funds received by the Administrative Agent from the Banks.

(e) Administrative Agent Reliance on Bank Funding. Unless the Administrative Agent shall have been notified by a Bank before the date on which such

60364071.5

Bank is scheduled to make payment to the Administrative Agent of the proceeds of a Loan (which notice shall be effective upon receipt) that such Bank does not intend to make such payment, the Administrative Agent may assume that such Bank has made such payment when due and the Administrative Agent may in reliance upon such assumption (but shall not be required to) make available to Borrower the proceeds of the Loan to be made by such Bank and, if any Bank has not in fact made such payment to the Administrative Agent, such Bank shall, on demand, pay to the Administrative Agent the amount made available to Borrower attributable to such Bank together with interest thereon in respect of each day during the period commencing on the date such amount was made available to Borrower and ending on (but excluding) the date such Bank pays such amount to the Administrative Agent at a rate per annum equal to (i) from the date the related payment was made by the Administrative Agent to the date two (2) Business Days after payment by such Bank is due hereunder, the Federal Funds Rate for each such day and (ii) from the date two (2) Business Days after the date such payment is due from such Bank to the date such payment is made by such Bank, the Base Rate in effect for each such day. If such amount is not received from such Bank by the Administrative Agent immediately upon demand, Borrower will, on demand, repay to the Administrative Agent the proceeds of the Loan attributable to such Bank with interest thereon at a rate per annum equal to the interest rate applicable to the relevant Loan.

Section 2.6 Interest Periods. As provided in Section 2.5(a) hereof, at the time of each request of a Borrowing of Eurodollar Loans, Borrower shall select an Interest Period applicable to such Loans from among the available options. The term “Interest Period” means the period commencing on the date a Borrowing of Loans is advanced, continued, or created by conversion and ending: (a) in the case of Base Rate Loans, on the last Business Day of the calendar quarter in which such Borrowing is advanced, continued, or created by conversion (or on the last day of the following calendar quarter if such Loan is advanced, continued or created by conversion on the last Business Day of a calendar quarter), and (b) in the case of Eurodollar Loans, 1, 2, 3, 6, or, if agreed to by the Administrative Agent, 12 months thereafter; provided, however, that:

(a) any Interest Period for a Borrowing of Base Rate Loans that otherwise would end after the Termination Date shall end on the Termination Date;

(b) for any Borrowing of Eurodollar Loans, Borrower may not select an Interest Period that extends beyond either (i) the fifth to last Business Day of any calendar year or (ii) the Termination Date;

(c) whenever the last day of any Interest Period would otherwise be a day that is not a Business Day, the last day of such Interest Period shall be extended to the next succeeding Business Day, provided that, if such extension would cause the last day of an Interest Period for a Borrowing of Eurodollar Loans to occur in the following calendar month, the last day of such Interest Period shall be the immediately preceding Business Day; and

(d) for purposes of determining an Interest Period for a Borrowing of Eurodollar Loans, a month means a period starting on one day in a calendar month and ending on the numerically corresponding day in the next calendar month; provided,

60364071.5

however, that if there is no numerically corresponding day in the month in which such an Interest Period is to end or if such an Interest Period begins on the last Business Day of a calendar month, then such Interest Period shall end on the last Business Day of the calendar month in which such Interest Period is to end.

Section 2.7 Maturity of Loans. Unless an earlier maturity is provided for hereunder (whether by acceleration or otherwise), all Obligations (including principal and interest on all outstanding Loans) shall mature and become due and payable by Borrower on the Termination Date.

Section 2.8 Prepayments.

(a) Borrower may prepay without premium or penalty and in whole or in part (but, if in part, then (i) in an amount not less than $5,000,000 and integral multiples of $1,000,000 in excess thereof, and (ii) in an amount such that the minimum amount required for a Borrowing pursuant to Section 2.4 hereof remains outstanding) any Borrowing of Eurodollar Loans upon three (3) Business Days’ prior irrevocable notice to the Administrative Agent or, in the case of a Borrowing of Base Rate Loans, irrevocable notice delivered to the Administrative Agent no later than 12:00 noon (New York time) on the date of prepayment, such prepayment to be made by the payment of the principal amount to be prepaid and accrued interest thereon to the date fixed for prepayment. In the case of Eurodollar Loans, any amounts owing under Section 2.11 hereof as a result of such prepayment shall be paid contemporaneously with such prepayment. The Administrative Agent will promptly advise each Bank of any such prepayment notice it receives from Borrower. Any amount paid or prepaid before the Termination Date may, subject to the terms and conditions of this Agreement, be borrowed, repaid and borrowed again.

(b) If the aggregate amount of outstanding Loans and L/C Obligations shall at any time for any reason exceed the Commitments then in effect or the amount of L/C Obligations at any time outstanding attributable to Marketing Subsidiary Letters of Credit exceeds the Marketing Subsidiary Sublimit, Borrower shall, immediately and without notice or demand, pay the amount of such excess to the Administrative Agent for the ratable benefit of the Banks as a prepayment of the Loans and, if necessary, a prefunding of Letters of Credit. Immediately upon determining the need to make any such prepayment Borrower shall notify the Administrative Agent of such required prepayment. Each such prepayment shall be accompanied by a payment of all accrued and unpaid interest on the Loans prepaid and shall be subject to Section 2.11.

Section 2.9 Default Rate. If any payment of principal or interest on any Loan, or payment of any other Obligation, is not made when due (whether by acceleration or otherwise), such principal, interest or other Obligation shall bear interest (computed on the basis of a year of 360 days and actual days elapsed or, if based on the rate described in clause (i) of the definition of Base Rate, on the basis of a year of 365 or 366 days, as applicable, and the actual number of days elapsed) from the date such payment was due until paid in full, payable on demand, at a rate per annum equal to:

60364071.5

(a) for any Obligation other than a Eurodollar Loan (including principal and interest relating to Base Rate Loans and interest on Eurodollar Loans), the sum of two percent (2%) plus the Applicable Margin plus the Base Rate from time to time in effect; and

(b) for the principal of any Eurodollar Loan, the sum of two percent (2%) plus the rate of interest in effect thereon at the time of such default until the end of the Interest Period applicable thereto and, thereafter, at a rate per annum equal to the sum of two percent (2%) plus the Applicable Margin plus the Base Rate from time to time in effect.

Section 2.10 The Notes.

(a) The Loans made to Borrower by each Bank shall be evidenced by a single promissory note of Borrower issued to such Bank in the form of Exhibit A hereto. Each such promissory note is hereinafter referred to as a “Note” and collectively such promissory notes are referred to as the “Notes.”

(b) Each Bank shall record on its books and records or on a schedule to its Note the amount of each Loan advanced, continued, or converted by it, all payments of principal and interest and the principal balance from time to time outstanding thereon, the type of such Loan, and, for any Eurodollar Loan, the Interest Period and the interest rate applicable thereto. The record thereof, whether shown on such books and records of a Bank or on a schedule to any Note, shall be prima facie evidence of the same; provided, however, that the failure of any Bank to record any of the foregoing or any error in any such record shall not limit or otherwise affect the obligation of Borrower to repay all Loans made hereunder together with accrued interest thereon. At the request of any Bank and upon such Bank tendering to Borrower the Note to be replaced, Borrower shall furnish a new Note to such Bank to replace any outstanding Note, and at such time the first notation appearing on a schedule on the reverse side of, or attached to, such Note shall set forth the aggregate unpaid principal amount of all Loans, if any, then outstanding thereon.

Section 2.11 Funding Indemnity. If any Bank shall incur any loss, cost or expense (including, without limitation, any loss, cost or expense (excluding loss of margin) incurred by reason of the liquidation or re-employment of deposits or other funds acquired by such Bank to fund or maintain any Eurodollar Loan or the relending or reinvesting of such deposits or amounts paid or prepaid to such Bank) as a result of:

(a) any payment (whether by acceleration or otherwise), prepayment or conversion of a Eurodollar Loan on a date other than the last day of its Interest Period,

(b) any failure (because of a failure to meet the conditions of Section 6 or otherwise) by Borrower to borrow or continue a Eurodollar Loan, or to convert a Base Rate Loan into a Eurodollar Loan, on the date specified in a notice given pursuant to Section 2.5(a) or established pursuant to Section 2.5(c) hereof,

(c) any failure by Borrower to make any payment or prepayment of principal on any Eurodollar Loan when due (whether by acceleration or otherwise), or

60364071.5

(d) any acceleration of the maturity of a Eurodollar Loan as a result of the occurrence of any Event of Default hereunder,

(e) then, upon the demand of such Bank, Borrower shall pay to such Bank such amount as will reimburse such Bank for such loss, cost or expense. If any Bank makes such a claim for compensation, it shall provide to Borrower, with a copy to the Administrative Agent, a certificate executed by an officer of such Bank setting forth the amount of such loss, cost or expense in reasonable detail (including an explanation of the basis for and the computation of such loss, cost or expense) and the amounts shown on such certificate if reasonably calculated shall be prima facie evidence of the amount of such loss, cost or expense.

Section 2.12 Commitments.

(a) Borrower shall have the right at any time and from time to time, upon five (5) Business Days’ prior written notice to the Administrative Agent, to terminate the Commitments without premium or penalty, in whole or in part, any partial termination to be (i) in an amount not less than $5,000,000 and integral multiples of $1,000,000 in excess thereof, and (ii) allocated ratably among the Banks in proportion to their respective Percentages, provided that the Commitments may not be reduced to an amount less than the sum of the Loans and all L/C Obligations then outstanding. The Administrative Agent shall give prompt notice to each Bank of any such termination of Commitments. Any termination of Commitments pursuant to this Section 2.12 may not be reinstated.

(b) The Borrower and the Administrative Agent may from time to time add additional financial institutions as parties to this Agreement or, with the written consent of an existing Bank, increase the Commitment of such existing Bank (any such financial institution or existing Bank which is increasing its commitment being referred to as an “Added Bank”) pursuant to documentation reasonably satisfactory to the Borrower and the Administrative Agent and any such Added Bank shall for all purposes be considered a Bank for purposes of this Agreement and the other Credit Documents with a Commitment as set forth in such documentation. Any such Added Bank shall on the date it is deemed a party to this Agreement purchase from the other Banks its Percentage (or the increase in its Percentage, in the case of an Added Bank which is an existing Bank) of the Loans outstanding and shall be deemed to purchase pursuant to Section 2.2(d) a Participating Interest in all Letters of Credit and Reimbursement Obligations outstanding on such date to the extent of its Percentage (or the increase in its Percentage, in the case of an Added Bank which is an existing Bank). Notwithstanding anything contained in this Section 2.12(b) to the contrary, the aggregate amount of Commitments may not at any time exceed $500,000,000 without the consent of the Required Banks.

Section 2.13 BHP Borrowings. The Borrower agrees to reserve under the Commitments at all times an aggregate amount equal to $3,100,000 (the “BHP Reserve”) to be used by the Borrower to fund, directly or indirectly, any liquidity needs arising under or in connection with that certain Loan Agreement between the City of Gillette, Campbell County, Wyoming and BHP (fka Black Hills Corporation), dated June 1, 1994, as such Loan Agreement is amended,

60364071.5

modified, supplemented or refinanced from time to time (the “BHP Liquidity Requirements”). The BHP Reserve shall be: (i) reduced for each Loan requested by the Borrower, the proceeds of which are used to fund, directly or indirectly, the BHP Liquidity Requirements, and (ii) increased, up to the limit of $3,100,000 at any time, for any such Loan that is repaid in accordance with the terms of this Agreement. Nothing in this paragraph shall restrict Borrower’s use of other Loans made under this Agreement in accordance with the terms and conditions of this Agreement. The Administrative Agent and the Banks shall have no responsibility for ensuring that the proceeds of Loans made under the BHP Reserve are used for the BHP Liquidity Requirements.

SECTION 3. FEES.

Section 3.1 Fees.

(a) Facility Fee. From and after the Effective Date, Borrower shall pay to the Administrative Agent for the ratable account of the Banks in accordance with their Percentages a facility fee accruing at a rate per annum equal to the Facility Fee Rate on the average daily amount of the Commitments (whether used or unused), or if the Commitments have expired or terminated, on the principal amount of Loans and L/C Obligations then outstanding. Such facility fee is payable in arrears on the last Business Day of each calendar quarter and on the Termination Date, and if the Commitments are terminated in whole prior to the Termination Date, the fee for the period to but not including the date of such termination shall be paid in whole on the date of such termination.

SECTION 5. REPRESENTATIONS AND WARRANTIES.

The Borrower hereby represents and warrants to each Bank as to itself and, where the following representations and warranties apply to its Subsidiaries, as to each Subsidiary of Borrower, as follows:

Section 5.1 Corporate Organization and Authority. Borrower is duly organized and existing in good standing under the laws of the state of South Dakota; has all necessary corporate power to carry on its present business; and is duly licensed or qualified and in good standing in each jurisdiction in which the nature of the business transacted by it or the nature of the Property owned or leased by it makes such licensing, qualification or good standing necessary and in which the failure to be so licensed, qualified or in good standing would have a Material Adverse Effect.

Section 5.2 Subsidiaries. Schedule 5.2 (as updated from time to time pursuant to Section 7.1) hereto identifies each Subsidiary of Borrower, the jurisdiction of organization, the percentage of issued and outstanding equity securities owned by the Borrower and its Subsidiaries and, if such percentage is not one hundred percent (100%) (excluding directors’ qualifying shares as required by law), a description of each class of its equity securities and the number of securities issued and outstanding. Each Subsidiary is duly organized and existing in good standing under the laws of the jurisdiction of its organization, has all necessary corporate or equivalent power to carry on its present business, and is duly licensed or qualified and in good standing in each jurisdiction in which the nature of the business transacted by it or the nature of the Property owned or leased by it makes such licensing or qualification necessary and in which the failure to be so licensed or qualified would have a Material Adverse Effect. All of the issued and outstanding securities of each Subsidiary owned directly or indirectly by Borrower are validly issued and outstanding and fully paid and nonassessable except as set forth on Schedule 5.2 hereto. All such securities owned by Borrower are owned beneficially, and of record, free of any Lien, except as permitted in Section 7.9.

Section 5.3 Corporate Authority and Validity of Obligations. Borrower has full right and authority to enter into this Agreement and the other Credit Documents to which it is a party, to make the borrowings herein provided for, to issue its Notes in evidence thereof, to apply (and to have applied) for the issuance of the Letters of Credit, and to perform all of its obligations under the Credit Documents to which it is a party. Each Credit Document to which it is a party has been duly authorized, executed and delivered by Borrower and constitutes valid and binding obligations of Borrower enforceable in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforceability of creditors’ rights generally and by equitable principles of general

60364071.5

applicability (regardless of whether such enforceability is considered in a proceeding in equity or at law). No Credit Document, nor the performance or observance by Borrower of any of the matters or things therein provided for, contravenes any provision of law or any charter or by-law provision of Borrower or any material Contractual Obligation of or affecting Borrower or any of Borrower’s Properties or results in or requires the creation or imposition of any Lien on any of the Properties or revenues of Borrower.

Section 5.4 Financial Statements. All financial statements heretofore delivered to the Banks showing historical performance of Borrower for Borrower’s fiscal years ending on or before December 31, 2004, have been prepared in accordance generally accepted accounting principles applied on a basis consistent, except as otherwise noted therein, with that of the previous fiscal year. The unaudited financial statements for the fiscal period ended March 31, 2005 have been prepared in accordance generally accepted accounting principles applicable to interim financial statements applied on a basis consistent, except as otherwise noted therein, with the previous same fiscal period of Borrower in the prior fiscal year (subject to normal year-end adjustments). Each of such financial statements fairly presents on a consolidated basis the financial condition of Borrower and its Subsidiaries as of the dates thereof and the results of operations for the periods covered thereby. Borrower and its Subsidiaries have no material contingent liabilities other than those disclosed in such financial statements referred to in this Section 5.4 or in comments or footnotes thereto, or in any report supplementary thereto, heretofore furnished to the Banks. Since December 31, 2004, there has been no event or series of events which has resulted in, or reasonably could be expected to result in, a Material Adverse Effect.

Section 5.5 No Litigation; No Labor Controversies.

(a) Except as set forth on Schedule 5.5, there is no litigation or governmental proceeding pending, or to the knowledge of Borrower, threatened, against Borrower or any Subsidiary of Borrower in which there is a reasonable possibility of an adverse decision which, if adversely determined, could (individually or in the aggregate) have a Material Adverse Effect.

(b) Except as set forth on Schedule 5.5, there are no labor controversies pending or, to the best knowledge of Borrower, threatened against Borrower or any Subsidiary of Borrower which could (individually or in the aggregate) have a Material Adverse Effect.

Section 5.6 Taxes. Borrower and its Subsidiaries have filed all United States federal tax returns, and all other foreign, state, local and other tax returns, required to be filed and have paid all taxes due pursuant to such returns or pursuant to any assessment received by Borrower or any Subsidiary of Borrower, except such taxes, if any, as are being contested in good faith and for which adequate reserves have been provided. No notices of tax liens have been filed and no claims are being asserted concerning any such taxes, which liens or claims are material to the financial condition of Borrower or any of its Subsidiaries (individually or in the aggregate). The charges, accruals and reserves on the books of Borrower and its Subsidiaries for any taxes or other governmental charges are adequate and in conformance with GAAP.

60364071.5

Section 5.7 Approvals. No authorization, consent, approval, license, exemption, filing or registration with any court or governmental department, agency or instrumentality which have not already been obtained, nor any approval or consent of the stockholders of Borrower or any Subsidiary of Borrower or from any other Person, is necessary to the valid execution, delivery or performance by Borrower or any Subsidiary of Borrower of any Credit Document to which it is a party.

Section 5.8 ERISA. With respect to each Plan, Borrower and each other member of the Controlled Group has fulfilled its obligations under the minimum funding standards of and is in compliance in all material respects with the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and with the Code to the extent applicable to it and has not incurred any liability to the Pension Benefit Guaranty Corporation (“PBGC”) or a Plan under Title IV of ERISA other than a liability to the PBGC for premiums under Section 4007 of ERISA. Neither Borrower nor any Subsidiary of Borrower has any contingent liabilities for any post-retirement benefits under a Welfare Plan, other than liability for continuation coverage described in Part 6 of Title I of ERISA.

Section 5.9 Government Regulation.

(a) Neither Borrower nor any Subsidiary of Borrower is an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

(b) Borrower is a “registered holding company” within the meaning of PUHCA, and the entering into of, and the performance by the Borrower of its obligations under, the Credit Documents (including its utilization of the credit provided for under the Credit Documents) (x) does not violate PUHCA or the rules promulgated thereunder (including by the SEC), and (y) has received all necessary approvals required pursuant to PUHCA and the rules promulgated thereunder (including by the SEC).

Section 5.10 Margin Stock; Use of Proceeds. Neither Borrower nor any Subsidiary of Borrower is engaged principally, or as one of its primary activities, in the business of extending credit for the purpose of purchasing or carrying margin stock (“margin stock” to have the same meaning herein as in Regulation U of the Board of Governors of the Federal Reserve System). The proceeds of the Loans and Letters of Credit are to be used solely (i) to fund Borrower’s working capital needs, and (ii) for general corporate purposes of Borrower. Borrower will not use the proceeds of any Loan or Letter of Credit in a manner that violates any provision of Regulation U or X of the Board of Governors of the Federal Reserve System.

Section 5.11 Licenses and Authorizations; Compliance with Laws.

(a) Borrower and each of its Subsidiaries has all necessary licenses, permits and governmental authorizations to own and operate its Properties and to carry on its business as currently conducted and contemplated. Borrower and each of its Subsidiaries is in compliance with all applicable laws, regulations, ordinances and orders of any governmental or judicial authorities except for any such law, regulation, ordinance or order which, the failure to comply therewith, could not reasonably expected to have a Material Adverse Effect.

60364071.5

(b) In the ordinary course of its business, Borrower and each of its Subsidiaries conduct an ongoing review of the effect of Environmental and Health Laws on the Properties and all aspects of the business and operations of such Borrower and its Subsidiaries in the course of which such Borrower identifies and evaluates associated liabilities and costs (including, without limitation, any capital or operating expenditures required for clean-up or closure of Properties currently or previously owned, any capital or operating expenditures required to achieve or maintain compliance with standards imposed by law and any actual or potential liabilities to third parties, including employees or governmental entities, and any related costs and expenses). On the basis of this review, Borrower has reasonably concluded that Environmental and Health Laws are unlikely to have any Material Adverse Effect.

(c) Except as set forth on Schedule 5.11 (as amended from time to time in accordance with the provisions hereof), neither the Borrower nor any Subsidiary of Borrower has given, nor is it required to give, nor has it received, any notice, letter, citation, order, warning, complaint, inquiry, claim or demand to or from any governmental entity or in connection with any court proceeding which could reasonably have a Material Adverse Effect claiming that: (i) Borrower or any Subsidiary of Borrower has violated, or is about to violate, any Environmental and Health Law; (ii) there has been a release, or there is a threat of release, of Hazardous Materials from Borrower’s or any of its Subsidiary’s Property, facilities, equipment or vehicles; (iii) Borrower or any of its Subsidiary may be or is liable, in whole or in part, for the costs of cleaning up, remediating or responding to a release of Hazardous Materials; or (iv) any of Borrower’s or any of its Subsidiary’s Property or assets are subject to a Lien in favor of any governmental entity for any liability, costs or damages, under any Environmental and Health Law arising from, or costs incurred by such governmental entity in response to, a release of a Hazardous Materials.

All information heretofore furnished by Borrower to the Administrative Agent or any Bank for purposes of or in connection with the Credit Documents or any transaction contemplated thereby is, and all such information hereafter furnished by Borrower to the Administrative Agent or any Bank will be, true and accurate in all material respects and not misleading.

(b) All amounts prepaid pursuant to subsection (a) above shall be held by the Administrative Agent in a separate collateral account (such account, and the credit balances, properties and any investments from time to time held therein, and any substitutions for such account, any certificate of deposit or other instrument evidencing any of the foregoing and all proceeds of and earnings on any of the foregoing being collectively called the “Account”) as security for, and for application by the Administrative Agent (to the extent available) to, the reimbursement of any payment under any Letter of Credit then or thereafter made by the Issuing Agents, and to the payment of the unpaid balance of any Loans and all other Obligations. The Account shall be held in the name of and subject to the exclusive dominion and control of the Administrative Agent for the benefit of the Administrative Agent, the Issuing Agents and the Banks, and Borrower hereby grants to the Administrative Agent, for the benefit of the Administrative Agent, the Issuing Agents and the Banks, a security interest in all of Borrower’s rights, title and interest in and to the Account and all property (including investment property) contained therein or credited thereto. So long as no Default or Event of Default has occurred, if and when requested by Borrower, the Administrative Agent shall invest funds held in the Account from time to time in direct obligations of, or obligations the principal of and interest on which are unconditionally guaranteed by, the United States of America with a remaining maturity of one year or less, provided, that the Administrative Agent is irrevocably authorized to sell investments held in the Account when and as required to make payments out of the Account for application to amounts due and owing from Borrower to the Administrative Agent, the Issuing Agents or Banks, and provided, further, that if a Default or Event of Default has then occurred and is continuing, Borrower shall have no access to or right to control the Account. If (i)

60364071.5

Borrower shall have made payment of all such obligations referred to in subsection (a) above, (ii) all relevant preference or other disgorgement periods relating to the receipt of such payments have passed, and (iii) no Letters of Credit, Commitments, Loans or other Obligations remain outstanding hereunder, then the Administrative Agent shall repay to Borrower any remaining amounts held in the Account.

Section 8.5 Expenses. Borrower agrees to pay to the Administrative Agent, the Issuing Agents and each Bank, and any other holder of any Note outstanding hereunder, all costs and expenses incurred or paid by the Administrative Agent, the Issuing Agents or such Bank or any such holder, including attorneys’ fees (including allocable fees of in-house counsel) and court costs, in connection with (i) any amendment or waiver to the Credit Documents requested by Borrower, (ii) any Default or Event of Default by Borrower hereunder, or (iii) the enforcement of any of the Credit Documents.

SECTION 9. CHANGE IN CIRCUMSTANCES.

Section 9.1 Change of Law. Notwithstanding any other provisions of this Agreement or any Note, if at any time after the date hereof any change in applicable law or regulation or in the interpretation thereof makes it unlawful for any Bank to make or continue to maintain Eurodollar Loans or to perform its obligations as contemplated hereby, such Bank shall promptly give notice thereof to Borrower and such Bank’s obligations to make or maintain Eurodollar Loans under this Agreement shall terminate until it is no longer unlawful for such Bank to make or maintain Eurodollar Loans. Borrower shall prepay on demand the outstanding principal amount of any such affected Eurodollar Loans, together with all interest accrued thereon at a rate per annum equal to the interest rate applicable to such Loan; provided, however, subject to all of the terms and conditions of this Agreement, Borrower may then elect to borrow the principal amount of the affected Eurodollar Loans from such Bank by means of Base Rate Loans from such Bank, which Base Rate Loans shall not be made ratably by the Banks but only from such affected Bank.

Section 9.2 Unavailability of Deposits or Inability to Ascertain, or Inadequacy of, LIBOR. If on or prior to the first day of any Interest Period for any Borrowing of Eurodollar Loans:

(a) the Administrative Agent determines that deposits in U.S. Dollars (in the applicable amounts) are not being offered to major banks in the eurodollar interbank market for such Interest Period, or that by reason of circumstances affecting the interbank eurodollar market adequate and reasonable means do not exist for ascertaining the applicable LIBOR, or

(b) Banks having more than 33% percent (33)% or more of the aggregate amount of the Commitments reasonably determine and so advise the Administrative Agent that LIBOR as reasonably determined by the Administrative Agent will not adequately and fairly reflect the cost to such Banks or Bank of funding their or its Eurodollar Loans or Loan for such Interest Period,

60364071.5

then the Administrative Agent shall forthwith give notice thereof to Borrower and the Banks, whereupon until the Administrative Agent notifies Borrower that the circumstances giving rise to such suspension no longer exist, the obligations of the Banks or of the relevant Bank to make Eurodollar Loans shall be suspended.

Section 9.3 Increased Cost and Reduced Return.

(a) If, on or after the date hereof, the adoption of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Lending Office) with any request or directive (whether or not having the force of law but, if not having the force of law, compliance with which is customary in the relevant jurisdiction) of any such authority, central bank or comparable agency:

(i) shall subject any Bank (or its Lending Office) to any tax, duty or other charge with respect to its Eurodollar Loans, its Notes, its Letter(s) of Credit, or its participation in any thereof, any Reimbursement Obligations owed to it or its obligation to make Eurodollar Loans, issue a Letter of Credit, or to participate therein, or shall change the basis of taxation of payments to any Bank (or its Lending Office) of the principal of or interest on its Eurodollar Loans, Letter(s) of Credit, or participations therein or any other amounts due under this Agreement in respect of its Eurodollar Loans, Letter(s) of Credit, or participations therein, any Reimbursement Obligations owed to it, or its obligation to make Eurodollar Loans, issue a Letter of Credit, or acquire participations therein (except for changes in the rate of tax on the overall net income or profits of such Bank or its Lending Office imposed by the jurisdiction in which such Bank or its lending office is incorporated in which such Bank’s principal executive office or Lending Office is located); or

(ii) shall impose, modify or deem applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding with respect to any Eurodollar Loans any such requirement included in an applicable Eurodollar Reserve Percentage) against assets of, deposits with or for the account of, or credit extended by, any Bank (or its Lending Office) or shall impose on any Bank (or its Lending Office) or on the interbank market any other condition affecting its Eurodollar Loans, its Notes, its Letter(s) of Credit, or its participation in any thereof, any Reimbursement Obligation owed to it, or its obligation to make Eurodollar Loans, to issue a Letter of Credit, or to participate therein;

and the result of any of the foregoing is to increase the cost to such Bank (or its Lending Office) of making or maintaining any Eurodollar Loan, issuing or maintaining a Letter of Credit, or participating therein, or to reduce the amount of any sum received or receivable by such Bank (or its Lending Office) under this Agreement or under its Notes with respect thereto, by an amount deemed by such Bank to be material, then, within fifteen (15) days after demand by such Bank

60364071.5

(with a copy to the Administrative Agent), Borrower shall be obligated to pay to such Bank such additional amount or amounts as will compensate such Bank for such increased cost or reduction. In the event any law, rule, regulation or interpretation described above is revoked, declared invalid or inapplicable or is otherwise rescinded, and as a result thereof a Bank is determined to be entitled to a refund from the applicable authority for any amount or amounts which were paid or reimbursed by Borrower to such Bank hereunder, such Bank shall refund such amount or amounts to Borrower without interest.

(b) If, after the date hereof, any Bank or the Administrative Agent shall have determined that the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change therein (including, without limitation, any revision in the Final Risk-Based Capital Guidelines of the Board of Governors of the Federal Reserve System (12 CFR Part 208, Appendix A; 12 CFR Part 225, Appendix A) or of the Office of the Comptroller of the Currency (12 CFR Part 3, Appendix A), or in any other applicable capital rules heretofore adopted and issued by any governmental authority), or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Lending Office) with any request or directive regarding capital adequacy (whether or not having the force of law but, if not having the force of law, compliance with which is customary in the applicable jurisdiction) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Bank’s capital, or on the capital of any corporation controlling such Bank, as a consequence of its obligations hereunder to a level below that which such Bank could have achieved but for such adoption, change or compliance (taking into consideration such Bank’s policies with respect to capital adequacy) by an amount deemed by such Bank to be material, then from time to time, within fifteen (15) days after demand by such Bank (with a copy to the Administrative Agent), Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such reduction.

(c) Each Bank that determines to seek compensation under this Section 9.3 shall notify Borrower and the Administrative Agent of the circumstances that entitle the Bank to such compensation pursuant to this Section 9.3 and will designate a different Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole judgment of such Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank claiming compensation under this Section 9.3 and setting forth the additional amount or amounts to be paid to it hereunder submitted to Borrower and the Administrative Agent by such Bank in good faith shall be prima facie evidence of the amount of such compensation. In determining such amount, such Bank may use any reasonable averaging and attribution methods.

Section 9.4 Lending Offices. Each Bank may, at its option, elect to make its Loans hereunder at the branch, office or affiliate specified on the appropriate signature page hereof or in the assignment agreement which any assignee bank executes pursuant to Section 11.12 hereof (each a “Lending Office”) for each type of Loan available hereunder or at such other of its branches, offices or affiliates as it may from time to time elect and designate in a written notice

60364071.5

to Borrower and the Administrative Agent, so long as such election does not increase costs or other amounts payable by Borrower to such Bank hereunder.

Section 9.5 Discretion of Bank as to Manner of Funding. Notwithstanding any other provision of this Agreement, each Bank shall be entitled to fund and maintain its funding of all or any part of its Loans in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if each Bank had actually funded and maintained each Eurodollar Loan through the purchase of deposits in the eurodollar interbank market having a maturity corresponding to such Loan’s Interest Period and bearing an interest rate equal to LIBOR for such Interest Period.

SECTION 10. THE AGENT.

Section 10.1 Appointment and Authorization of Administrative Agent. Each Bank hereby appoints ABN AMRO Bank N.V. as the Administrative Agent under the Credit Documents and hereby authorizes the Administrative Agent to take such action as Administrative Agent on its behalf and to exercise such powers under the Credit Documents as are delegated to the Administrative Agent by the terms thereof, together with such powers as are reasonably incidental thereto. The Administrative Agent shall have no duties or responsibilities except those expressly set forth in this Agreement and the Credit Documents. The duties of the Administrative Agent shall be mechanical and administrative in nature; the Administrative Agent shall not have by reason of this Agreement or any other Credit Document a fiduciary relationship in respect of any Bank, the holder of any Note or any other Person; and nothing in this Agreement or any other Credit Document, expressed or implied, is intended to or shall be so construed as to impose upon the Administrative Agent any obligations in respect of this Agreement or any other Credit Document except as expressly set forth herein or therein.

Section 10.2 Administrative Agent and its Affiliates. The Administrative Agent shall have the same rights and powers under this Agreement and the other Credit Documents as any other Bank and may exercise or refrain from exercising the same as though it were not the Administrative Agent, and the Administrative Agent and its affiliates may accept deposits from, lend money to, and generally engage in any kind of business with Borrower or any Affiliate of Borrower as if it were not the Administrative Agent under the Credit Documents.

Section 10.3 Action by Administrative Agent. If the Administrative Agent receives from Borrower a written notice of an Event of Default pursuant to Section 7.6(c)(i) hereof, the Administrative Agent shall promptly give each of the Banks written notice thereof. The obligations of the Administrative Agent under the Credit Documents are only those expressly set forth therein. Without limiting the generality of the foregoing, the Administrative Agent shall not be required to take any action hereunder with respect to any Default or Event of Default, except as expressly provided in Sections 8.2 and 8.3. In no event, however, shall the Administrative Agent be required to take any action in violation of applicable law or of any provision of any Credit Document, and the Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder or under any other Credit Document unless it shall be first indemnified to its reasonable satisfaction by the Banks against any and all costs, expense, and liability which may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall be entitled to assume that no Default or Event of Default

60364071.5

exists unless notified to the contrary in writing by a Bank or Borrower. In all cases in which this Agreement and the other Credit Documents do not require the Administrative Agent to take certain actions, the Administrative Agent shall be fully justified in using its discretion in failing to take or in taking any action hereunder and thereunder.

Section 10.4 Consultation with Experts. The Administrative Agent may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts.

Section 10.5 Liability of Administrative Agent; Credit Decision. Neither the Administrative Agent nor any of its directors, officers, agents, or employees shall be liable for any action taken or not taken by it in connection with the Credit Documents (i) with the consent or at the request of the Required Banks or (ii) in the absence of its own gross negligence or willful misconduct. Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into or verify (i) any statement, warranty or representation made in connection with this Agreement, any other Credit Document or any Credit Event; (ii) the performance or observance of any of the covenants or agreements of Borrower or any other party contained herein or in any other Credit Document; (iii) the satisfaction of any condition specified in Section 6 hereof; or (iv) the validity, effectiveness, genuineness, enforceability, perfection, value, worth or collectibility hereof or of any other Credit Document or of any other documents or writing furnished in connection with any Credit Document; and the Administrative Agent makes no representation of any kind or character with respect to any such matter mentioned in this sentence. The Administrative Agent may execute any of its duties under any of the Credit Documents by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Banks, Borrower, or any other Person for the default or misconduct of any such agents or attorneys-in-fact selected with reasonable care. The Administrative Agent shall not incur any liability by acting in reliance upon any notice, consent, certificate, other document or statement (whether written or oral) believed by it to be genuine or to be sent by the proper party or parties. In particular and without limiting any of the foregoing, the Administrative Agent shall have no responsibility for confirming the accuracy of any Compliance Certificate or other document or instrument received by it under the Credit Documents. The Administrative Agent may treat the payee of any Note as the holder thereof until written notice of transfer shall have been filed with the Administrative Agent signed by such payee in form satisfactory to the Administrative Agent. Each Bank acknowledges that it has independently and without reliance on the Administrative Agent or any other Bank, and based upon such information, investigations and inquiries as it deems appropriate, made its own credit analysis and decision to extend credit to Borrower in the manner set forth in the Credit Documents. It shall be the responsibility of each Bank to keep itself informed as to the creditworthiness of Borrower and any other relevant Person, and the Administrative Agent shall have no liability to any Bank with respect thereto.

Section 10.6 Indemnity. The Banks shall ratably, in accordance with their respective Percentages, indemnify and hold the Administrative Agent, and its directors, officers, employees, agents and representatives harmless from and against any liabilities, losses, costs or expenses suffered or incurred by it under any Credit Document or in connection with the transactions contemplated thereby, regardless of when asserted or arising, except to the extent the

60364071.5

Administrative Agent is promptly reimbursed for the same by Borrower and except to the extent that any event giving rise to a claim was caused by the gross negligence or willful misconduct of the party seeking to be indemnified. The obligations of the Banks under this Section 10.6 shall survive termination of this Agreement.

Section 10.7 Resignation of Administrative Agent and Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Banks and Borrower. Upon any such resignation of the Administrative Agent, the Required Banks shall have the right to appoint a successor Administrative Agent with the consent of Borrower. If no successor Administrative Agent shall have been so appointed by the Required Banks, and shall have accepted such appointment, within thirty (30) days after the retiring Administrative Agent’s giving of notice of resignation, then the retiring Administrative Agent may, on behalf of the Banks, appoint a successor Administrative Agent, which shall be any Bank hereunder or any commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $200,000,000. Upon the acceptance of its appointment as the Administrative Agent hereunder, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring or removed Administrative Agent under the Credit Documents, and the retiring Administrative Agent shall be discharged from its duties and obligations thereunder. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Section 10 and all protective provisions of the other Credit Documents shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent.

SECTION 11. MISCELLANEOUS.

Section 11.1 Withholding Taxes.

(a) Payments Free of Withholding. Subject to Section 11.1 (b) hereof, each payment by Borrower under this Agreement or the other Credit Documents shall be made without withholding for or on account of any present or future taxes (other than overall net income taxes on the recipient). If any such withholding is so required, Borrower shall make the withholding, pay the amount withheld to the appropriate governmental authority before penalties attach thereto or interest accrues thereon and forthwith pay such additional amount as may be necessary to ensure that the net amount actually received by each Bank and the Administrative Agent free and clear of such taxes (including such taxes on such additional amount) is equal to the amount which that Bank or the Administrative Agent (as the case may be) would have received had such withholding not been made. If the Administrative Agent or any Bank pays any amount in respect of any such taxes, penalties or interest Borrower shall reimburse the Administrative Agent or that Bank for that payment on demand in the currency in which such payment was made. If Borrower pay any such taxes, penalties or interest, they shall deliver official tax receipts evidencing that payment or certified copies thereof to the Bank or Administrative Agent on whose account such withholding was made (with a copy to the Administrative Agent if not the recipient of the original) on or before the thirtieth day after payment. If any Bank or the Administrative Agent determines it has received or been granted a credit against or relief or remission for, or repayment of, any taxes paid or payable by it because of any taxes, penalties or interest paid by Borrower

60364071.5

and evidenced by such a tax receipt, such Bank or Administrative Agent shall, to the extent it can do so without prejudice to the retention of the amount of such credit, relief, remission or repayment, pay to Borrower such amount as such Bank or Administrative Agent determines is attributable to such deduction or withholding and which will leave such Bank or Administrative Agent (after such payment) in no better or worse position than it would have been in if Borrower had not been required to make such deduction or withholding. Nothing in this Agreement shall interfere with the right of each Bank and the Administrative Agent to arrange its tax affairs in whatever manner it thinks fit nor obligate any Bank or the Administrative Agent to disclose any information relating to its tax affairs or any computations in connection with such taxes.

(b) U.S. Withholding Tax Exemptions. Each Bank that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) shall submit to Borrower and the Administrative Agent on or before the date of the initial Borrowing hereunder two duly completed and signed copies of either Form W8BEN (relating to such Bank and entitling it to a complete exemption from withholding under the Code on all amounts to be received by such Bank, including fees, pursuant to the Credit Documents and the Loans) or Form W8ECI (relating to all amounts to be received by such Bank, including fees, pursuant to the Credit Documents and the Loans) of the United States Internal Revenue Service. Thereafter and from time to time, each Bank shall submit to Borrower and the Administrative Agent such additional duly completed and signed copies of one or the other of such Forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may be (i) requested by Borrower in a written notice, directly or through the Administrative Agent, to such Bank and (ii) required under then current United States law or regulations to avoid or reduce United States withholding taxes on payments in respect of all amounts to be received by such Bank, including fees, pursuant to the Credit Documents or the Loans.

(c) Inability of Bank to Submit Forms. If any Bank determines, as a result of any change in applicable law, regulation or treaty, or in any official application or interpretation thereof, that it is unable to submit to Borrower or Administrative Agent any form or certificate that such Bank is obligated to submit pursuant to subsection (b) of this Section 11.1 or that such Bank is required to withdraw or cancel any such form or certificate previously submitted or any such form or certificate otherwise becomes ineffective or inaccurate, such Bank shall promptly notify Borrower and Administrative Agent of such fact and the Bank shall to that extent not be obligated to provide any such form or certificate and will be entitled to withdraw or cancel any affected form or certificate, as applicable.

Section 11.2 No Waiver of Rights. No delay or failure on the part of the Administrative Agent or any Bank or on the part of the holder or holders of any Note in the exercise of any power or right under any Credit Document shall operate as a waiver thereof, nor as an acquiescence in any default, nor shall any single or partial exercise thereof preclude any other or further exercise of any other power or right, and the rights and remedies hereunder of the Administrative Agent, the Banks and the holder or holders of any Notes are cumulative to, and not exclusive of, any rights or remedies which any of them would otherwise have.

60364071.5

Section 11.3 Non-Business Day. If any payment of principal or interest on any Loan or of any other Obligation shall fall due on a day which is not a Business Day, interest or fees (as applicable) at the rate, if any, such Loan or other Obligation bears for the period prior to maturity shall continue to accrue on such Obligation from the stated due date thereof to and including the next succeeding Business Day, on which the same shall be payable.

Section 11.4 Documentary Taxes. Borrower agrees that it will pay any documentary, stamp or similar taxes payable in respect to any Credit Document, including interest and penalties, in the event any such taxes are assessed, irrespective of when such assessment is made and whether or not any credit is then in use or available hereunder.

Section 11.5 Survival of Representations. All representations and warranties made herein or in certificates given pursuant hereto shall survive the execution and delivery of this Agreement and the other Credit Documents, and shall continue in full force and effect with respect to the date as of which they were made as long as any credit is in use or available hereunder.

Section 11.6 Survival of Indemnities. All indemnities and all other provisions relative to reimbursement to the Banks of amounts sufficient to protect the yield of the Banks with respect to the Loans, including, but not limited to, Section 2.11, Section 9.3 and Section 11.13 hereof, shall survive the termination of this Agreement and the other Credit Documents and the payment of the Loans and all other Obligations.

Section 11.7 Set-Off.

(a) In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, upon the occurrence of any Event of Default, each Bank and each subsequent holder of any Note is hereby authorized by Borrower at any time or from time to time, without notice to Borrower or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, Indebtedness evidenced by certificates of deposit, whether matured or unmatured, or otherwise fully matured, and in whatever currency denominated) and any other Indebtedness at any time held or owing by that Bank or that subsequent holder to or for the credit or the account of Borrower, whether or not matured, against and on account of the obligations and liabilities of Borrower to that Bank or that subsequent holder under the Credit Documents, including, but not limited to, all claims of any nature or description arising out of or connected with the Credit Documents, irrespective of whether or not (a) that Bank or that subsequent holder shall have made any demand hereunder or (b) the principal of or the interest on the Loans or Notes and other amounts due hereunder shall have become due and payable pursuant to Section 8 and although said obligations and liabilities, or any of them, may be contingent or unmatured.

(b) Each Bank agrees with each other Bank a party hereto that if such Bank shall receive and retain any payment, whether by set-off or application of deposit balances or otherwise, on any of the Loans or Reimbursement Obligations in excess of its ratable share of payments on all such obligations then outstanding to the Banks, then such

60364071.5

Bank shall purchase for cash at face value, but without recourse, ratably from each of the other Banks such amount of the Loans or Reimbursement Obligations, or participations therein, held by each such other Banks (or interest therein) as shall be necessary to cause such Bank to share such excess payment ratably with all the other Banks; provided, however, that if any such purchase is made by any Bank, and if such excess payment or part thereof is thereafter recovered from such purchasing Bank, the related purchases from the other Banks shall be rescinded ratably and the purchase price restored as to the portion of such excess payment so recovered, but without interest. For purposes of this Section 11.7(b), amounts owed to or recovered by, an Issuing Agent in connection with Reimbursement Obligations in which Banks have been required to fund their participation shall be treated as amounts owed to or recovered by such Issuing Agent as a Bank hereunder.

Section 11.8 Notices. Except as otherwise specified herein, all notices under the Credit Documents shall be in writing (including facsimile or other electronic communication) and shall be given to a party hereunder at its address or facsimile number set forth below or such other address or facsimile number as such party may hereafter specify by notice to the Administrative Agent and Borrower, given by courier, by United States certified or registered mail, or by other telecommunication device capable of creating a written record of such notice and its receipt.

Section 11.10 Successors and Assigns.

(a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign any of its rights or obligations under any Credit Document unless such assignation occurs in connection with a merger or acquisition by Borrower which is otherwise permitted under the terms of this Agreement and the appropriate Credit Documents, if applicable, and Borrower obtains the prior written consent of all of the Banks, which consent shall be in form and substance satisfactory to the Administrative Agent. No Bank may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the

60364071.5

Related Parties of each of the Administrative Agent and the Banks) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Banks. Any Bank may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that

(i) except in the case of an assignment of the entire remaining amount of the assigning Bank’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Bank or an Affiliate of a Bank or an Approved Fund with respect to a Bank, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loan of the assigning Bank subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower, otherwise consents (each such consent not to be unreasonably withheld or delayed);

(ii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Bank’s rights and obligations under this Agreement with respect to the Loan, L/C Obligations or the Commitment assigned;

(iii) any assignment of a Commitment must be approved by the Administrative Agent and the Issuing Agent unless the Person that is the proposed assignee is itself a Bank with a Commitment (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee); and

(iv) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500, and the Eligible Assignee, if it shall not be a Bank, shall deliver to the Administrative Agent an Administrative Questionnaire.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Bank under this Agreement, and the assigning Bank thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Bank’s rights and obligations under this Agreement, such Bank shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 9.3 and 9.4 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any

assignment or transfer by a Bank of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Bank of a participation in such rights and obligations in accordance with paragraph (d) of this Section. The Borrower shall execute and deliver to the assignee a Note upon written request from such assignee. The assignor shall promptly return to the Borrower its Note if after giving effect to such assignment such assignor has no Commitment and no Obligations are owing to such assignor.

(c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in Chicago, Illinois a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Banks, and the Commitments of, and principal amounts of the Loans owing to, each Bank pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Banks may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Bank hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Bank, at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Bank may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Bank’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Bank’s obligations under this Agreement shall remain unchanged, (ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other Banks shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this Agreement.

(e) Any agreement or instrument pursuant to which a Bank sells such a participation shall provide that such Bank shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Bank will not, without the consent of the Participant, agree to any amendment, modification or waiver of the type described in Section 11.11(i) that affects such Participant. Subject to paragraph (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 9.3 and 9.4 to the same extent as if it were a Bank and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.7(a) as though it were a Bank, provided such Participant agrees to be subject to Section 11.7(b) as though it were a Bank.

(f) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Sections 9.3 and 9.4 than the applicable Bank would have been entitled to receive with respect to the participation sold to such Participant,

60364071.5

unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Bank if it were a Bank shall not be entitled to the benefits of Section 9.4 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 9.4 as though it were a Bank.

(g) Certain Pledges. Any Bank may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Bank, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Bank from any of its obligations hereunder or substitute any such pledgee or assignee for such Bank as a party hereto.

(h) Certain Funding Arrangements. Notwithstanding anything to the contrary contained herein, any Bank (a “Granting Bank”) may grant to a special purpose funding vehicle which is an Affiliate of such Bank (a “SPC”), identified as such in writing from time to time by the Granting Bank to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Loan that such Granting Bank would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Bank shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Bank to the same extent, and as if, such Loan were made by such Granting Bank. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Bank). 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. In addition, notwithstanding anything to the contrary contained in this Section 11.10, any SPC may (i) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Bank or to any financial institutions (consented to by the Borrower and Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This section may not be amended without the written consent of the SPC.

(i) Farm Credit System. Notwithstanding anything in this Section to the contrary, any bank that is a member of the Farm Credit System that: (x) has purchased a participation in the minimum amount of $10,000,000 on or after the Effective Date, (y) is, by written notice to the Borrower and the Administrative Agent ("Voting Participant

60364071.5

Notification"), designated by the selling Bank as being entitled to be accorded the rights of a Voting Participant hereunder (any bank that is a member of the Farm Credit System so designated being called a "Voting Participant") and (z) receives the prior written consent of the Borrower and the Administrative Agent to become a Voting Participant, shall be entitled to vote (and the voting rights of the selling Bank shall be correspondingly reduced), on a dollar for dollar basis, as if such participant were a Bank, on any matter requiring or allowing a Bank to provide or withhold its consent, or to otherwise vote on any proposed action. To be effective, each Voting Participant Notification shall, with respect to any Voting Participant: (i) state the full name, as well as all contact information required of an Assignee as set forth in Exhibit D hereto and (ii) state the dollar amount of the participation purchased. The Borrower and the Administrative Agent shall be entitled to conclusively rely on information contained in notices delivered pursuant to this paragraph.

Section 11.11 Amendments. Any provision of the Credit Documents may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by (a) Borrower, (b) the Required Banks, and (c) if the rights or duties of the Administrative Agent are affected thereby, the Administrative Agent; provided that:

(i) no amendment or waiver pursuant to this Section. 11.11 shall (A) increase, decrease or extend any Commitment of any Bank without the consent of such Bank or (B) reduce the amount of or postpone any fixed date for payment of any principal of or interest on any Loan or Reimbursement Obligation or of any fee or other Obligation payable hereunder without the consent of each Bank; and

(ii) no amendment or waiver pursuant to this Section 11.11 shall, unless signed by each Bank, change this Section 11.11, or the definition of Required Banks, or affect the number of Banks required to take any action under the Credit Documents.

Anything in this Agreement to the contrary notwithstanding, if at any time when the conditions precedent set forth in Section 6.2 hereof to any Loan hereunder are satisfied, any Bank shall fail to fulfill its obligations to make such Loan or such Bank shall fail to fund its Participating Interest pursuant to Section 2.2(d) (any such Bank, a “Defaulting Bank”) then, for so long as such failure shall continue, the Defaulting Bank shall (unless Borrower, the Administrative Agent and the Required Banks (determined as if the Defaulting Bank were not a Bank hereunder) shall otherwise consent in writing) be deemed for all purposes related to amendments, modifications, waivers or consents under this Agreement (other than amendments or waivers referred to in clause (i) and (ii) above) to have no Loans or Commitments and shall not be treated as a Bank hereunder when performing the computation of the Required Banks. To the extent the Administrative Agent receives any payments or other amounts for the account of a Defaulting Bank such Defaulting Bank shall be deemed to have requested that the Administrative Agent use such payment or other amount first, to fund its purchase of its Participating Interest pursuant to Section 2.2(d) and secondly, to fulfill its obligations to make such Loan.

Borrower, upon demand by any of the Administrative Agent, an Issuing Agent or a Bank at any time, shall reimburse the Administrative Agent, such Issuing Agent or Bank for any reasonable legal or other expenses (including allocable fees and expenses of in-house counsel) incurred in connection with investigating or defending against any of the foregoing except if the same is directly due to the gross negligence or willful misconduct of the party to be indemnified, provided that with respect to legal costs and expenses incurred in connection with the enforcement of the Banks rights hereunder or any work-out or similar situation, Borrower shall only be obligated to pay the legal fees of the Administrative Agent and not of any other Bank.

Section 11.14 Entire Agreement. The Credit Documents constitute the entire understanding of the parties thereto with respect to the subject matter thereof and any prior or contemporaneous agreements, whether written or oral, with respect thereto are superseded thereby.

Section 11.15 Construction. The parties hereto acknowledge and agree that neither this Agreement nor the other Credit Documents shall be construed more favorably in favor of one than the other based upon which party drafted the same, it being acknowledged that all parties hereto contributed substantially to the negotiation of this Agreement and the other Credit Documents.

BORROWER IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. BORROWER HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO ANY CREDIT DOCUMENT OR THE TRANSACTIONS CONTEMPLATED THEREBY.

Section 11.18 Replacement of Bank. Each Bank agrees that, upon the occurrence of any event set forth in Sections 9.1, 9.3 and 11.1, such Bank will use reasonable efforts to book and maintain its Loans through a different Lending Office or to transfer its Loans to an Affiliate with the objective of avoiding or minimizing the consequences of such event; provided that such booking or transfer is not otherwise disadvantageous to such Bank as determined by such Bank in its sole and absolute discretion. If any Bank has demanded to be paid additional amounts pursuant to Sections 9.1, 9.3 and 11.1, and the payment of such additional amounts are, and are likely to continue to be, more onerous in the reasonable judgment of Borrower than with respect to the other Banks, then Borrower shall have the right at any time when no Default or Event of Default shall have occurred and be continuing to seek one or more financial institutions which are not Affiliates of Borrower (each, a “Replacement Bank”) to purchase with the written consent of the Administrative Agent (which consent shall not be (x) required if such proposed Replacement Bank is already a Bank, or an Affiliate of a Bank, or (y) unreasonably delayed or withheld) the outstanding Loans and Commitments of such Bank (the “Affected Bank”), and if Borrower locate a Replacement Bank, the Affected Bank shall, upon

iii.	satisfaction of the provisions set forth in Section 11.10, and

iv.	payment by Borrower to the Affected Bank and the Administrative Agent of all reasonable out-of-pocket expenses in connection with such assignment and assumption (including the recordation fee described in Section 11.10),

60364071.5

assign and delegate all its rights and obligations under this Agreement and any other Credit Document to which it is a party (including its outstanding Loans) to the Replacement Bank (such assignment to be made without recourse, representation or warranty), and the Replacement Bank shall assume such rights and obligations, whereupon the Replacement Bank shall in accordance with Section 11.10 become a party to each Credit Document to which the Affected Bank is a party and shall have the rights and obligations of a Bank thereunder and the Affected Bank shall be released from its obligations hereunder and each other Credit Document to the extent of such assignment and delegation.

Section 11.19 Confidentiality. The Administrative Agent and the Banks shall hold all non-public information provided to them by Borrower pursuant to or in connection with this Agreement in accordance with their customary procedures for handling confidential information of this nature, but may make disclosure to any of their examiners, regulators, Affiliates, outside auditors, counsel and other professional advisors in connection with this Agreement or any other Credit Document or as reasonably required by any potential bona fide transferee, participant or assignee, or in connection with the exercise of remedies under a Credit Document, or to any direct or indirect contractual counterparty in swap agreements or such contractual counterparty’s professional advisor (so long as such contractual counterparty or professional advisor to such contractual counterparty agrees to be bound by the provisions of this Section 11.19), or to any nationally recognized rating agency that requires access to information about a Bank’s investment portfolio in connection with ratings issued with respect to such Bank, or as requested by any governmental agency or representative thereof or pursuant to legal process; provided, however, that unless specifically prohibited by applicable law or court order, the Administrative Agent and each Bank shall use reasonable efforts to promptly notify Borrower of any request by any governmental agency or representative thereof (other than any such request in connection with an examination of the financial condition of the Administrative Agent or such Bank by such governmental agency) for disclosure of any such non-public information and, where practicable, prior to disclosure of such information. Prior to any such disclosure pursuant to this Section 11.19, the Administrative Agent and each Bank shall require any such bona fide transferee, participant and assignee receiving a disclosure of non-public information to agree, for the benefit of Borrower, in writing to be bound by this Section 11.19; and to require such Person to require any other Person to whom such Person discloses such non-public information to be similarly bound by this Section 11.19.

Notwithstanding anything herein to the contrary, “confidential information” shall not include, and the Administrative Agent and each Bank may disclose to any and all persons, without limitation of any kind, any information with respect to the U.S. federal income tax treatment and U.S. federal income tax structure of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to the Administrative Agent or such Bank relating to such tax treatment and tax structure.

Section 11.20 Rights and Liabilities of Co-Syndication Agents, Co-Documentation Agents and Arrangers. Neither any Co-Syndication Agent, any Co-Documentation Agent nor any Arranger have any special rights, powers, obligations, liabilities, responsibilities or duties under this Agreement as a result of acting in the capacity of Co-Syndication Agent, Co-Documentation Agent or Arranger, as applicable, other than those applicable to them in their capacity as Banks hereunder (if any). Without limiting the foregoing, neither any Co-

60364071.5

Syndication Agent, any Co-Documentation Agent nor any Arranger shall have or be deemed to have a fiduciary relationship with any Bank. Each Bank hereby makes the same acknowledgments and undertakings with respect to each Co-Syndication Agent, each Co-Documentation Agent and each Arranger as it makes with respect to the Administrative Agent and any directors, officers, agents and employees of the Administrative Agent in Section 10.5.

Section 11.22 Severability of Provisions. Any provision in this Agreement or any other Credit Document that is held to be inoperative, unenforceable, or invalid in any jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, or invalid without affecting the remaining provisions in that jurisdiction or the operation, enforceability, or validity of that provision in any other jurisdiction, and to this end the provisions of this Agreement and the other Credit Documents are declared to be severable.

LITIGATION AND LABOR CONTROVERSIES

1.	Hell Canyon Fire

In September 2001, a fire occurred in the southwestern Black Hills. It is alleged that the fire occurred when a high voltage electrical span maintained by Black Hills Power, Inc. (“BHP”) broke, and electrical arching from the severed line ignited dry grass. The fire burned approximately 10,000 acres of land owned by the Black Hills National Forest, the Oglala Sioux Tribe, and other private landowners. The State of South Dakota initiated litigation against BHP, in the Seventh Judicial Circuit Court, Fall River County, South Dakota, on or about January 31, 2003. The Complaint seeks recovery of damages for alleged fire suppression and rehabilitation costs. A claim for treble damages is asserted with respect to the claim for injury to timber. A substantially similar suit was filed against BHP by the United States Forest Service, on June 30, 2003, in the United States District Court for the District of South Dakota, Western Division. The State subsequently joined its claim in the federal action. The State claims damages in the amount of approximately $800,000 for fire suppression and rehabilitation costs. The United States Government’s claim for fire suppression and related costs has been submitted at approximately $1,300,000. The Company continues to investigate the cause and origin of the fire, and the damage claims. A trial date is expected in 2005. The Company has denied all claims and will vigorously defend this matter, the timing or outcome of which is uncertain.

2.	Smith v. Black Hills Energy Resources, Inc.

In this litigation, private landowners have sued Black Hills Energy Resources (“BHER”) and Wickford Energy Marketing Company (the predecessor of BHER) in state court in the state of Arkansas. The lawsuit alleges claims against a number of oil producing and marketing Defendants as a consequence of an alleged oil spill affecting private property. BHER allegedly purchased oil directly from the production facility for truck transport. It did not have an ownership or operating interest in the production facility or the pipeline from which the spill allegedly occurred. BHER filed a Motion to Dismiss All Claims. The court denied BHER’s motion in order to allow limited discovery to proceed. A tentative settlement agreement in the amount of $12,000 has been reached, pending approval of final documentation.

3.	Grizzly Gulch Fire

On June 29, 2002, a forest fire began near Deadwood, South Dakota. Before being contained more than eight days later, the fire consumed over 10,000 acres of public and private land, mostly consisting of rugged forested areas. The fire destroyed approximately 7 homes, and 15 outbuildings. There were no reported personal injuries. In addition, the fire burned to the edge of the City of Deadwood, forcing the evacuation of the City of Deadwood, and the adjacent City of Lead, South Dakota. These communities are active in the tourist and gaming industries. Individuals were ordered to leave their homes, and businesses were closed for a short period of time. On July 16, 2002, the State of South Dakota announced the results of its investigation of the cause and origin of the fire. The State asserted that the fire was caused by tree encroachment

Credit Agreement

into and contact with a transmission line owned and maintained by Black Hills Power, Inc. (“BHP”).

On September 6, 2002, the State of South Dakota commenced litigation against BHP, in the Seventh Judicial Circuit Court, Pennington County, South Dakota. The Complaint seeks recovery of damages for alleged injury to timber, fire suppression and rehabilitation costs. A claim for treble damages is asserted with respect to the claim for injury to timber.

On March 3, 2003, the United States of America filed a similar suit against BHP, in the United States District Court, District of South Dakota, Western Division. The federal government’s Complaint likewise seeks recovery of damages for alleged injury to timber, fire suppression and rehabilitation costs. A similar claim for treble damages is asserted with respect to the claim for injury to timber. In April 2003, the State of South Dakota intervened in the federal action. Accordingly, the state court litigation will be stayed, and all governmental claims will be tried in U.S. District Court.

The state and federal government have claimed approximately $5,300,000 for suppression costs, $1,200,000 for rehabilitation costs, and $610,000 for timber loss (which could be trebled). Additional claims could be asserted for alleged loss of habitat and aesthetics or for assistance to private landowners.

BHP is completing its own investigation of the fire cause and origin. BHP’s investigation is continuing, but based upon information currently available, BHP filed its Answer to the Complaints of both the State and the federal government, denying all claims, and asserting that the fire was caused by an independent intervening cause, or an act of God. The Company expects to vigorously defend all claims brought by governmental or private parties.

4.	Price Reporting Class Actions

A.	Cornerstone Propane Partners, L.P.

On August 18, 2003, Cornerstone Propane Partners, L.P. commenced a putative class action lawsuit against over thirty energy companies. Cornerstone Propane Partners, L.P. v. Reliant Energy Services, Inc., et. al., Civ. No. 03-CV-6168 (U.S. District Court, Southern District of New York)(“Cornerstone Propane Litigation”). The Complaint, which names Enserco Energy Inc. as a defendant, asserts claims for an unspecified amount of damages, based upon alleged violations of the Commodity Exchange Act. General allegations in the Complaint assert that defendants manipulated natural gas futures contracts through false reporting of prices and volumes. Similar specific allegations are made against Enserco, based upon claims that former traders at Enserco reported false price and volume information to trade publications. Other defendants are alleged to have manipulated spot market gas prices by engaging in “wash trades” and/or by “churning” natural gas trades. Initially, the plaintiff seeks an order certifying the proceeding as a class action according to applicable rules. Enserco has denied all claims for damages and will vigorously defend this action, beginning with the request for class certification. Enserco cannot predict the outcome of this litigation, but based upon information currently available to the Company, we believe the likelihood that the action would have a material adverse effect upon its financial condition and results of operations is remote.

B.	Roberto E. Calle Gracey

On October 1, 2003, Roberto E. Calle Gracey commenced a putative class action lawsuit against a group of defendants that sets forth claims and demands similar to those described above with respect to the Cornerstone Propane Litigation. Black Hills Corporation and Enserco Energy, Inc. are named as defendants in this action as well. Gracey v. American Electric Power Company, Inc., et. al., Civ. No., 03-CV-7750 (U.S. District Court, Southern District of New York). Black Hills and Enserco will deny all claims for damages and vigorously defend this action, beginning with the request for class certification. Black Hills Corporation cannot predict the outcome of this litigation, but based upon information currently available to the Company, we believe the likelihood that the action would have a material adverse effect upon its financial condition and results of operations is remote.

C.	In re Natural Gas Commodity Litigation

Credit Agreement

On December 5, 2003, the actions cited in paragraphs A and B were consolidated, with other actions involving similar claims against other parties, in a civil action captioned In re Natural Gas Commodity Litigation, 03 CV 6186(VM), United States District Court, Southern District of New York. All further proceedings relative to these matters will be conducted in the consolidated action. The consolidated class action now includes claims against a number of companies, based upon a variety of alleged misconduct. The claims against Enserco comprise a relatively small part of only one category of the total claims included in this lawsuit. The action has not been certified to proceed as a class action. Motions to Dismiss were denied. Defendants will make an effort to “decertify” the matter as a class action based upon the dissimilarity of parties, claims and issues. While it is possible for an individual to state a claim for relief based upon allegations such as those made against Enserco, those Plaintiffs that have asserted claims against Enserco have a number of procedural and substantive hurdles to overcome. Even if Plaintiffs’ claims survive Motions to Dismiss, and successfully avoid class decertification, they still must prove actual damages as a result of the conduct of an individual Defendant, such as Enserco. Based upon information currently available, and given the current status of the litigation, we do not believe it is likely that Plaintiffs will be able to succeed in recovering on a claim that would be material to Enserco.

5.	Black Hills Power, Inc./PacifiCorp Power Marketing Dispute

On January 2, 2004, PPM Energy, Inc. (“PPM”) delivered its Demand for Arbitration to Black Hills Power, Inc. (“BHP”). The Demand alleges claims for breach of contract and requests a declaration of the parties’ rights and responsibilities under an Exchange Agreement executed on or about April 3, 2001. Specifically, PPM asserts that the Exchange Agreement obligates BHP to accept receipt and cause corresponding delivery of electric energy, and to grant access to transmission rights allegedly covered by the Agreement. PPM requests an award of damages in an amount not less than $20,000,000. BHP denies all claims and will vigorously defend this matter, the timing and outcome of which is uncertain. BHP filed its Response to Demand, including a Counterclaim that seeks recovery of sums PPM has refused to pay pursuant to the Exchange Agreement. The arbitration is scheduled for hearing in early June, 2005.

6.	Elley v. Black Hills Power, Inc.

On March 8, 2004, Black Hills Power, Inc. (“BHP”) was served with a Complaint by Mae Elley and Patty Elley. The Complaint seeks recovery for alleged excessive cutting of trees, as well as treble and exemplary damages. The Company filed its Answer on May 7, 2004. On July 1, 2004, BHP served a Third Party Complaint against Willson’s Tree Service, Inc. for contribution and/or indemnification. Plaintiffs filed a Motion for Summary Judgment. The court granted Plaintiffs’ motion on the issue of treble damages only. A trial date is expected in 2005. The Company will vigorously defend this matter.

7.	Earn-Out Litigation

On August 13, 2004, Gerald R. Forsythe and other individuals identified at “Stockholders” under an Agreement and Plan of Merger dated July 7, 2000, commenced litigation against Black Hills Corporation in United States District Court, Northeastern District of Illinois, Eastern Division. The lawsuit concerns the Company’s performance of its obligations

Credit Agreement

under the “Earn-Out” provisions of the Agreement and Plan of Merger. Under these provisions, the Stockholders, who are former owners of Indeck Capital, Inc., were entitled to receive “contingent merger consideration” for a period of four years following the merger of Indeck Capital with Black Hills Energy Capital, Inc. The Stockholders allege that Black Hills failed to meet its obligation to produce documentation for its calculation of the contingent merger consideration, and in addition, failed to issue stock compensation in the full amount due to them. Black Hills denies these allegations and contends that it has fully and in good faith performed all of its obligations under the Agreement and Plan of Merger. In addition, Black Hills contends that the Agreement and Plan of Merger provides for mandatory arbitration as a medium for resolution of all disputes relating to the payment of contingent merger consideration, and will aggressively pursue the dismissal of the litigation.

The parties are currently sharing information and documentation, and have agreed that the federal court may issue a subpoena relating to the work papers of Deloitte & Touche. For that limited purpose alone, the court may supervise limited discovery, following which Black Hills will seek enforcement of the contractual remedy of arbitration. The outcome of this matter is uncertain, as is the amount of contingent merger consideration that could be awarded following arbitration or litigation.

8.	Peter C. Gasner v. A.O. Smith Corp., et al.

On February 7, 2005, Black Hills Corporation received service of process for a lawsuit captioned Peter C. Gasner v. A.O. Smith Corp., et al., Cause No. 2004-42761, 11^th Judicial District Court of Harris County, Texas. This is a class action commenced under the Texas Rules of Civil Procedures. The Plaintiff alleges that during the course of his career, he was exposed to asbestos while working at the DuPont Chemical Plant in Victoria, Texas, among other facilities. The Defendants include a host of companies, large and small, that are divided into several categories. One group of Defendants is referred to as “Product Defendants,” another group is referred to as “Premises Defendants,” and the final group is called “Contractor Defendants.” Black Hills Corporation is named among the “Premises Defendants” (among a list of other parties) in which the only direct allegation is that Plaintiff was exposed to asbestos and asbestos-containing products while working at premises owned and controlled by Black Hills Corporation. The parties have reached a settlement on all issues. Final documentation of a full and final settlement, with dismissal of all claims, is being prepared.

9.	Mallon Tax and Royalty Litigation

A.	Bayless/Jicarilla Lawsuit.

From January 1984 through December 1996, Robert L. Bayless operated the majority of the gas wells that Black Hills Exploration and Production (“BHEP”) ultimately acquired from Mallon Resources, Inc. (“Mallon”) in March 2003. Mallon owned a significant working interest in these wells during that time. The Department of Interior - Minerals Management Service (“MMS”) and the Jicarilla Apache Nation believed that Bayless had failed to pay royalties using the correct pricing analysis. Bayless disputed this claim and for at least the past six years fought this matter through proceedings with the Department of Interior - Internal Board of Land Appeals (“IBLA”),

Credit Agreement

mediation and finally under litigation against the Department of Interior, Jicarilla Apache Nation and the Department of Justice as filed in the United States District Court for the District of Columbia in Washington D.C. On behalf of itself, Mallon and other working interest owners, Bayless vigorously pursued this lawsuit. Bayless was forced to take extreme action because the Jicarilla Apache Nation had made claims in their earlier efforts to settle the matter that additional royalties from Bayless could amount to as much as $5,000,000 to $13,000,000 for the time period in question.

Following the merger (March 10, 2003), BHEP/Mallon worked with Jicarilla Apache officials, Bayless personnel, Fulbright & Jaworski lawyers and the MMS. On September 29, 2003, BHEP negotiated a mutually agreeable settlement that was executed by Bayless and the Jicarilla Apache Nation, settling the dispute for $1,250,000. BHEP’s share of this settlement was $664,725, not including legal fees. The Department of Justice and the Department of Interior ratified this settlement agreement and by Order dated July 29, 2004, the United States District Court for the District of Columbia dismissed the lawsuit with prejudice.

B.	Possessory Interest Tax (“PIT”) Lawsuit.

From 1998 through 2001, substantially all of the gas produced from approximately 130 wells within the East Blanco Field was processed through the Amine Plant. Based on the plain wording contained in Tribal Ordinances in effect at that time, Mallon considered the Amine Plant to be “production equipment”, and calculated and paid the resulting Possessory Interest Tax to the Nation. The Nation later assessed Mallon for PIT based on a change in regulations and retroactive application. Prior to the BHEP merger, Mallon paid the revised taxes and interests, under protest, totaling more than $3.3 million. The Jicarilla Department of Revenue and Taxation denied the protest. Mallon appealed to the Tribal Court of the Jicarilla Apache Nation for relief.

On September 8, 2003, BHEP successfully negotiated and executed a Tax Settlement Agreement and Mutual Release with the Jicarilla Apache Nation. On September 15, 2003, the Jicarilla Apache Tribal Court dismissed the lawsuit with prejudice and the corresponding lien on Mallon’s (now BHEP’s) properties was removed. The terms of the settlement waived all additional penalties and interest, in the amount of $260,269, culminating from Mallon’s late tax payment of $1.4 million for the 2002 tax year. To date, all Possessory Interest Tax that has been assessed and billed have been paid.
