NOTES TO CONSOLIDATED
FINANCIAL STATEMENTS

June 30, 2005 and 2004
(Unaudited)

1. Basis of presentation

The accompanying consolidated interim financial statements were prepared in conformity with the basis of presentation reflected in the consolidated financial statements included in the Annual Report to Stockholders on Form 10-K for the year ended December 31, 2004 (2004 Annual Report), and the standards of accounting measurement set forth in Accounting Principles Board (APB) Opinion No. 28 and any amendments thereto adopted by the Financial Accounting Standards Board (FASB). Interim financial statements do not include all disclosures provided in annual financial statements and, accordingly, these financial statements should be read in conjunction with those appearing in the Company's 2004 Annual Report. The information is unaudited but includes all adjustments that are, in the opinion of management, necessary for a fair presentation of the accompanying consolidated interim financial statements.

2. Seasonality of operations

Some of the Company's operations are highly seasonal and revenues from, and certain expenses for, such operations may fluctuate significantly among quarterly periods. Accordingly, the interim results for particular businesses, and for the Company as a whole, may not be indicative of results for the full fiscal year.

3. Allowance for doubtful accounts

The Company's allowance for doubtful accounts as of June 30, 2005 and 2004, and December 31, 2004, was $7.4 million, $8.0 million and $6.8 million, respectively.

4. Natural gas in underground storage

Natural gas in underground storage for the Company's regulated operations is carried at cost using the last-in, first-out method. The portion of the cost of natural gas in underground storage expected to be used within one year was included in inventories and was $7.2 million, $5.2 million and $24.9 million at June 30, 2005 and 2004, and December 31, 2004, respectively. The remainder of natural gas in underground storage was included in other assets and was $43.3 million, $42.6 million, and $43.3 million at June 30, 2005 and 2004, and December 31, 2004, respectively.

5. Inventories

Inventories, other than natural gas in underground storage for the Company's regulated operations, consisted primarily of aggregates held for resale of $84.2 million, $68.1 million and $71.0 million; materials and supplies of $45.8 million, $36.0 million and $31.0 million; and other inventories of $21.7 million, $12.6 million and $17.0 million; as of June 30, 2005 and 2004, and December 31, 2004, respectively. These inventories were stated at the lower of average cost or market.

6. Earnings per common share

Basic earnings per common share were computed by dividing earnings on common stock by the weighted average number of shares of common stock outstanding during the applicable period. Diluted earnings per common share were computed by dividing earnings on common stock by the total of the weighted average number of shares of common stock outstanding during the applicable period, plus the effect of outstanding stock options, restricted stock grants and performance share awards. For the three and six months ended June 30, 2004, 205,305 shares with an average exercise price of $24.54, attributable to the exercise of outstanding stock options, were excluded from the calculation of diluted earnings per share because their effect was antidilutive. For the three and six months ended June 30, 2005 and 2004, no adjustments were made to reported earnings in the computation of earnings per share. Common stock outstanding includes issued shares less shares held in treasury.

7. Stock-based compensation

The Company has stock option plans for directors, key employees and employees. In 2003, the Company adopted the fair value recognition provisions of Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation," and began expensing the fair market value of stock options for all awards granted on or after January 1, 2003. Compensation expense recognized for awards granted on or after January 1, 2003, for the six months ended June 30, 2005, was $4,000 (after tax). Compensation expense recognized for awards granted on or after January 1, 2003, for the three and six months ended June 30, 2004, was $2,000 and $5,000, respectively (after tax).

As permitted by SFAS No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure - an amendment of SFAS No. 123," the Company accounts for stock options granted prior to January 1, 2003, under APB Opinion No. 25, "Accounting for Stock Issued to Employees." No compensation expense has been recognized for stock options granted prior to January 1, 2003, as the options granted had an exercise price equal to the market value of the underlying common stock on the date of grant.

The Company adopted SFAS No. 123 effective January 1, 2003, for newly granted options only. The following table illustrates the effect on earnings and earnings per common share for the three and six months ended June 30, 2005 and 2004, as if the Company had applied SFAS No. 123 and recognized compensation expense for all outstanding and unvested stock options based on the fair value at the date of grant:

9. Reclassifications

Certain reclassifications have been made in the financial statements for the prior year to conform to the current presentation. Such reclassifications had no effect on net income or stockholders' equity as previously reported.

10. New accounting standards

SAB No. 106

In September 2004, the Securities and Exchange Commission (SEC) issued Staff Accounting Bulletin No. 106 (SAB No. 106) which is an interpretation regarding the application of SFAS No. 143, "Accounting for Asset Retirement Obligations" by oil and gas producing companies following the full-cost accounting method. SAB No. 106 clarifies that the future cash outflows associated with settling asset retirement obligations that have been accrued on the balance sheet should be excluded from the computation of the present value of estimated future net revenues for purposes of the full-cost ceiling calculation. SAB No. 106 also states that a company is expected to disclose in the financial statement footnotes and MD&A how the company's calculation of the ceiling test and depreciation, depletion and amortization are affected by the adoption of SFAS No. 143. SAB No. 106 was effective for the Company as of January 1, 2005. The adoption of SAB No. 106 did not have a material effect on the Company's financial position or results of operations. The effects of the adoption of SFAS No. 143 and SAB No. 106 as they relate to the Company's natural gas and oil production properties are described below.

Ceiling Test Calculation

As discussed in Note 1 of the 2004 Annual Report, the Company's natural gas and oil production properties are subject to a "ceiling test" that limits capitalized costs to the aggregate of the present value of future net revenues of proved reserves based on single point-in-time spot market prices, as mandated under the rules of the SEC, and the cost of unproved properties. Prior to the adoption of SFAS No. 143, the Company calculated the full-cost ceiling by reducing its expected future revenues from proved natural gas and oil reserves by the estimated future expenditures to be incurred in developing and producing such reserves, including future retirements, discounted using a factor mandated by the rules of the SEC. While expected future cash flows related to the asset retirement obligations were included in the calculation of the ceiling test, no associated asset retirement obligation was recognized on the balance sheet.

Upon the adoption of SFAS No. 143 but prior to the effective date of SAB No. 106, the Company continued to calculate the full-cost ceiling as previously described. In addition, the Company recorded the fair value of a liability for the asset retirement obligation and capitalized the cost by increasing the carrying amount of the related long-lived asset. Upon the adoption of SAB No. 106, the future capitalized discounted cash outflows associated with settling asset retirement obligations that are accrued on the consolidated balance sheet are excluded from the computation of the present value of estimated future net revenues for purposes of the full- cost ceiling calculation in accordance with SAB No. 106.

Depreciation, Depletion, and Amortization

Costs subject to amortization include: (A) all capitalized costs, less accumulated amortization, other than the cost of acquiring and evaluating unproved property; (B) the estimated future expenditures (based on current costs) to be incurred in developing proved reserves; and (C) estimated dismantlement and abandonment costs, net of estimated salvage values.

Subsequent to the adoption of SFAS No. 143, the estimated future dismantlement and abandonment costs described in (C) above are included in the capitalized costs described in (A) above at the expected future cost discounted to the present value, to the extent that a legal obligation exists. Under SFAS No. 143, the recognition of the asset retirement obligation does not take into account estimated salvage values. The liability associated with the recognition of an asset retirement obligation is accreted over time with accretion expense recorded in depreciation, depletion, and amortization expense on the income statement. The Company's estimated dismantlement and abandonment costs as described in (C) above were adjusted to account for asset retirement obligations accrued on the consolidated balance sheet when calculating the depreciation, depletion and amortization rates. In addition, estimated salvage values were included in the Company's depreciation, depletion and amortization calculation. The Company's estimate of future dismantlement and abandonment costs that will be incurred as a result of future development activities on proved reserves continues to be included in the calculation of costs to be amortized.

Any gains or losses on the settlement of an asset retirement obligation, if applicable, are treated as adjustments to the capitalized costs, consistent with the full-cost accounting method.

SFAS No. 123 (revised)

In December 2004, the FASB issued SFAS No. 123 (revised 2004), "Share-Based Payment" (SFAS No. 123 (revised)). SFAS No. 123 (revised) revises SFAS No. 123 and requires entities to recognize compensation expense in an amount equal to the fair value of share-based payments granted to employees. SFAS No.
123 (revised) requires a company to record compensation expense for all awards granted after the date of adoption of SFAS No.
123 (revised) and for the unvested portion of previously granted awards that remain outstanding at the date of adoption. SFAS No. 123 (revised) is effective for the Company on January 1, 2006. The Company is evaluating the effects of the adoption of SFAS No. 123 (revised).

FIN 47

In March 2005, the FASB issued FASB Interpretation No. 47, "Accounting for Conditional Asset Retirement Obligations - An Interpretation of FASB Statement No. 143" (FIN 47). FIN 47 addresses the diverse accounting practices that developed with respect to the timing of liability recognition for legal obligations associated with the retirement of a tangible long- lived asset when the timing and/or method of settlement of the obligation are conditional on a future event. FIN 47 concludes that an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation when incurred if the liability's fair value can be reasonably estimated. FIN 47 is effective for the Company at the end of the fiscal year ending December 31, 2005. The Company is evaluating the effects of the adoption of FIN 47.

EITF No. 04-6

In March 2005, the FASB ratified Emerging Issues Task Force Issue No. 04-6, "Accounting for Stripping Costs in the Mining Industry" (EITF No. 04-6). EITF No. 04-6 requires that post- production stripping costs be treated as a variable inventory production cost. As a result, such costs will be subject to inventory costing procedures in the period they are incurred. EITF No. 04-6 is effective for the Company on January 1, 2006. The Company is evaluating the effects of the adoption of EITF No. 04-6.

11. Comprehensive income

Comprehensive income is the sum of net income as reported and other comprehensive income (loss). The Company's other comprehensive income (loss) resulted from gains (losses) on derivative instruments qualifying as hedges and foreign currency translation adjustments. For more information on derivative instruments, see Note 14 of Notes to Consolidated Financial Statements.

Comprehensive income, and the components of other comprehensive income (loss) and related tax effects, were as follows:

12. Equity method investments

The Company has a number of equity method investments including Carib Power Management LLC (Carib Power) and Hartwell Energy Limited Partnership (Hartwell). The Company assesses its equity method investments for impairment whenever events or changes in circumstances indicate that the related carrying values may not be recoverable. None of the Company's equity method investments have been impaired and, accordingly, no impairment losses have been recorded in the accompanying consolidated financial statements or related equity method investment balances.

In February 2004, Centennial Energy Resources International, Inc. (Centennial International), an indirect wholly owned subsidiary of the Company, acquired 49.99 percent of Carib Power. Carib Power, through a wholly owned subsidiary, owns a 225-megawatt natural gas-fired electric generating facility located in Trinidad and Tobago (Trinity Generating Facility). The Trinity Generating Facility sells its output to the Trinidad and Tobago Electric Commission (T&TEC), the governmental entity responsible for the transmission, distribution and administration of electrical power to the national electrical grid of Trinidad and Tobago. The power purchase agreement expires in September 2029. T&TEC also is under contract to supply natural gas to the Trinity Generating Facility during the term of the power purchase contract. The functional currency for the Trinity Generating Facility is the U.S. dollar.

In September 2004, Centennial Resources, through wholly owned subsidiaries, acquired a 50-percent ownership interest in a 310- megawatt natural gas-fired electric generating facility located in Hartwell, Georgia (Hartwell Generating Facility). The Hartwell Generating Facility sells its output under a power purchase agreement with Oglethorpe Power Corporation (Oglethorpe) that expires in May 2019. Oglethorpe reimburses the Hartwell Generating Facility for actual costs of fuel acquired to operate the plant. American National Power, a wholly owned subsidiary of International Power of the United Kingdom, holds the remaining 50-percent ownership interest and is the operating partner for the facility.

In June 2005, an indirect wholly owned subsidiary of the Company completed the sale to Petrobras, the Brazilian state- controlled energy company, of its 49 percent interest in MPX Termoceara, Ltda. (MPX). The Company realized a gain of $15.6 million from the sale. MPX owns and operates a 220-megawatt natural gas-fired electric generating facility (Termoceara Generating Facility) in the Brazilian state of Ceara. Petrobras had entered into a contract to purchase all of the capacity and market all of the energy from the Termoceara Generating Facility. The electric power sales contract with Petrobras was scheduled to expire in mid-2008.

The functional currency for the Termoceara Generating Facility was the Brazilian Real. The electric power sales contract with Petrobras contained an embedded derivative, which derived its value from an annual adjustment factor, which largely indexed the contract capacity payments to the U.S. dollar. The Company's 49 percent share of the gain from the change in fair value of the embedded derivative in the electric power sales contract for the three and six months ended June 30, 2004, was $4.1 million (after tax). The Company's 49 percent share of the foreign currency loss resulting from the decrease in value of the Brazilian Real versus the U.S. dollar for the three and six months ended June 30, 2004, was $1.8 million (after tax) and $2.0 million (after tax), respectively.

In 2005, the Termoceara Generating Facility was accounted for as an asset held for sale and as a result no depreciation, depletion and amortization expense was recorded in 2005.

Centennial had unconditionally guaranteed a portion of certain bank borrowings of MPX. For more information on this guarantee, see Note 19.

At June 30, 2005, the Company's equity method investments, including Carib Power and Hartwell, had total assets of $243.6 million, and long-term debt of $159.6 million. At December 31, 2004, MPX, Carib Power and Hartwell had total assets of $334.2 million, and long-term debt of $224.9 million. At June 30, 2004, MPX and Carib Power had total assets of $202.8 million and long-term debt of $158.0 million. The Company's investment in its equity method investments, including the Trinity and Hartwell Generating Facilities, was approximately $43.4 million, including undistributed earnings of $2.6 million, at June 30, 2005. The Company's investment in the Termoceara, Trinity and Hartwell Generating Facilities was approximately $65.7 million, including undistributed earnings of $26.6 million, at December 31, 2004. The Company's investment in the Termoceara and Trinity Generating Facilities was approximately $26.0 million, including undistributed earnings of $14.8 million, at June 30, 2004.

Innovatum, Inc. (Innovatum), an indirect wholly owned subsidiary of the Company, which specializes in cable and pipeline magnetization and location, developed a hand-held locating device that can detect both magnetic and plastic materials, including unexploded ordnance. Innovatum was working with, and had demonstrated the device to, a Department of Defense contractor and had also met with individuals from the Department of Defense to discuss the possibility of using the hand-held locating device in their operations. In the third quarter of 2004, after communications with the Department of Defense, and delays in further testing resulting from a Department of Defense request to enhance the hand-held locating device, Innovatum decreased its expected future cash flows from the hand-held locating device. This decrease, coupled with the continued downturn in the telecommunications and energy industries, resulted in a revised earnings forecast for Innovatum, and as a result, a goodwill impairment loss of $4.0 million (before and after tax) was recognized in the third quarter of 2004. Innovatum, a reporting unit for goodwill impairment testing, is part of the pipeline and energy services segment. The fair value of Innovatum was estimated using the expected present value of future cash flows.

Other intangible assets were as follows:

The unamortizable intangible assets were recognized in accordance with SFAS No. 87, "Employers' Accounting for Pensions," which requires that if an additional minimum liability is recognized an equal amount shall be recognized as an intangible asset, provided that the asset recognized shall not exceed the amount of unrecognized prior service cost. The unamortizable intangible asset will be eliminated or adjusted as necessary upon a new determination of the amount of additional liability.

Amortization expense for amortizable intangible assets for the three and six months ended June 30, 2005 was $1.2 million and $2.1 million, respectively. Amortization expense for amortizable intangible assets for the three and six months ended June 30, 2004, and for the year ended December 31, 2004, was $702,000, $1.3 million and $3.8 million, respectively. Estimated amortization expense for amortizable intangible assets is $5.9 million in 2005, $6.0 million in 2006, $4.5 million in 2007, $4.0 million in 2008, $3.9 million in 2009 and $7.2 million thereafter.

14. Derivative instruments

From time to time, the Company utilizes derivative instruments as part of an overall energy price, foreign currency and interest rate risk management program to efficiently manage and minimize commodity price, foreign currency and interest rate risk. The following information should be read in conjunction with Notes 1 and 5 in the Company's Notes to Consolidated Financial Statements in the 2004 Annual Report.

As of June 30, 2005, Fidelity Exploration & Production Company (Fidelity), an indirect wholly owned subsidiary of the Company, held derivative instruments designated as cash flow hedging instruments.

Hedging activities

Fidelity utilizes natural gas and oil price swap and collar agreements to manage a portion of the market risk associated with fluctuations in the price of natural gas and oil on its forecasted sales of natural gas and oil production. Each of the natural gas and oil price swap and collar agreements was designated as a hedge of the forecasted sale of natural gas and oil production.

For the three and six months ended June 30, 2005 and 2004, the amount of hedge ineffectiveness, which was included in operating revenues, was immaterial. For the three and six months ended June 30, 2005 and 2004, Fidelity did not exclude any components of the derivative instruments' gain or loss from the assessment of hedge effectiveness and there were no reclassifications into earnings as a result of the discontinuance of hedges.

Gains and losses on derivative instruments that are reclassified from accumulated other comprehensive income (loss) to current-period earnings are included in the line item in which the hedged item is recorded. As of June 30, 2005, the maximum term of Fidelity's swap and collar agreements, in which it is hedging its exposure to the variability in future cash flows for forecasted transactions, is 18 months. Fidelity estimates that over the next 12 months net losses of approximately $13.7 million will be reclassified from accumulated other comprehensive loss into earnings, subject to changes in natural gas and oil market prices, as the hedged transactions affect earnings.

15. Business segment data

The Company's reportable segments are those that are based on the Company's method of internal reporting, which generally segregates the strategic business units due to differences in products, services and regulation. Prior to the fourth quarter of 2004, the Company reported six reportable segments consisting of electric, natural gas distribution, utility services, pipeline and energy services, natural gas and oil production and construction materials and mining. The independent power production and other operations did not individually meet the criteria to be considered a reportable segment. In the fourth quarter of 2004, the Company separated independent power production as a reportable business segment due to the significance of its operations. The Company's operations are now conducted through seven reportable segments and all prior period information has been restated to reflect this change.

The vast majority of the Company's operations are located within the United States. The Company also has investments in foreign countries, which largely consist of investments in natural resource-based projects.

The electric segment generates, transmits and distributes electricity, and the natural gas distribution segment distributes natural gas. These operations also supply related value-added products and services in the northern Great Plains.

The utility services segment specializes in electrical line construction, pipeline construction, inside electrical wiring and cabling, and the manufacture and distribution of specialty equipment.

The pipeline and energy services segment provides natural gas transportation, underground storage and gathering services through regulated and nonregulated pipeline systems primarily in the Rocky Mountain and northern Great Plains regions of the United States. The pipeline and energy services segment also provides energy-related management services, including cable and pipeline magnetization and locating.

The natural gas and oil production segment is engaged in natural gas and oil acquisition, exploration, development and production activities, primarily in the Rocky Mountain region of the United States and in and around the Gulf of Mexico.

The construction materials and mining segment mines aggregates and markets crushed stone, sand, gravel and related construction materials, including ready-mixed concrete, cement, asphalt and other value-added products, as well as performs integrated construction services, in the central and western United States and in the states of Alaska and Hawaii.

The independent power production segment owns, builds and operates electric generating facilities in the United States and has investments in domestic and international natural resource-based projects. Electric capacity and energy produced at its power plants are sold primarily under mid- and long-term contracts to nonaffiliated entities.

16. Acquisitions

During the first six months of 2005, the Company acquired utility services businesses in Nevada and construction materials and mining businesses in Idaho and Oregon, and natural gas and oil properties in south Texas, none of which was individually material. The total purchase consideration for these businesses and properties and purchase price adjustments with respect to certain other acquisitions acquired prior to 2005, including the Company's common stock and cash, was $192.9 million.

The above acquisitions were accounted for under the purchase method of accounting and, accordingly, the acquired assets and liabilities assumed have been preliminarily recorded at their respective fair values as of the date of acquisition. Final fair market values are pending the completion of the review of the relevant assets, liabilities and issues identified as of the acquisition date. The results of operations of the acquired businesses and properties are included in the financial statements since the date of each acquisition. Pro forma financial amounts reflecting the effects of the above acquisitions are not presented, as such acquisitions were not material to the Company's financial position or results of operations.

17. Employee benefit plans

The Company has noncontributory defined benefit pension plans and other postretirement benefit plans for certain eligible employees. The Company recognized the effects of the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (2003 Medicare Act) during the second quarter of 2004. Components of net periodic benefit cost for the Company's pension and other postretirement benefit plans were as follows:

In addition to the qualified plan defined pension benefits reflected in the table above, the Company also has an unfunded, nonqualified benefit plan for executive officers and certain key management employees that generally provides for defined benefit payments at age 65 following the employee's retirement or to their beneficiaries upon death for a 15-year period. The Company's net periodic benefit cost for this plan for the three and six months ended June 30, 2005, was $1.4 million and $3.3 million, respectively. The Company's net periodic benefit cost for this plan for the three and six months ended June 30, 2004, was $2.3 million and $3.8 million, respectively.

18. Regulatory matters and revenues subject to refund

On March 24, 2005, Montana-Dakota filed an application with the South Dakota Public Utilities Commission (SDPUC) for the East River service area for a natural gas rate increase. Montana- Dakota requested a total increase of $850,000 annually or 12.8 percent above current rates. A final order from the SDPUC is expected in late 2005.

In September 2004, Great Plains filed an application with the Minnesota Public Utilities Commission (MPUC) for a natural gas rate increase. Great Plains had requested a total increase of $1.4 million annually or approximately 4.0 percent above current rates. Great Plains also requested an interim increase of $1.4 million annually. In November 2004, the MPUC issued an Order authorizing an interim increase of $1.4 million annually effective with service rendered on or after January 10, 2005, subject to refund. A final order from the MPUC is expected in early 2006.

A liability has been provided for a portion of the revenues that have been collected subject to refund with respect to Great Plains' pending regulatory proceeding. Great Plains believes that the liability is adequate based on its assessment of the ultimate outcome of the proceeding.

In December 1999, Williston Basin Interstate Pipeline Company (Williston Basin), an indirect wholly owned subsidiary of the Company, filed a general natural gas rate change application with the Federal Energy Regulatory Commission (FERC). Williston Basin began collecting such rates effective June 1, 2000, subject to refund. In May 2001, the Administrative Law Judge (ALJ) issued an Initial Decision on Williston Basin's natural gas rate change application. The Initial Decision addressed numerous issues relating to the rate change application, including matters relating to allowable levels of rate base, return on common equity, and cost of service, as well as volumes established for purposes of cost recovery, and cost allocation and rate design. In July 2003, the FERC issued its Order on Initial Decision. The Order on Initial Decision affirmed the ALJ's Initial Decision on many of the issues including rate base and certain cost of service items as well as volumes to be used for purposes of cost recovery, and cost allocation and rate design. However, there were other issues as to which the FERC differed with the ALJ including return on common equity and the correct level of corporate overhead expense. In August 2003, Williston Basin requested rehearing of a number of issues including determinations associated with cost of service, throughput, and cost allocation and rate design, as discussed in the FERC's Order on Initial Decision. In May 2004, the FERC issued an Order on Rehearing. The Order on Rehearing denied rehearing on all of the issues addressed by Williston Basin in its August 2003 request for rehearing except for the issue of the proper rate to utilize for transmission system negative salvage expenses. In addition, the FERC remanded the issues regarding certain service and annual demand quantity restrictions to an ALJ for resolution. In June 2004, Williston Basin requested clarification of a few of the issues addressed in the Order on Rehearing including determinations associated with cost of service and cost allocation, as discussed in the FERC's Order on Rehearing. In June 2004, Williston Basin also made its filing to comply with the requirements of the various FERC orders in this proceeding. Williston Basin participated in a hearing before the ALJ in early January 2005, regarding certain service and annual demand quantity restrictions remanded to the ALJ by the FERC in its Order on Rehearing. On April 8, 2005, the ALJ issued an Initial Decision on the matters remanded by the FERC. In the Initial Decision, the ALJ decided that Williston Basin had not supported its position regarding the service and annual demand quantity restrictions. Williston Basin filed its Brief on Exceptions regarding these issues with the FERC on May 9, 2005, and its Brief Opposing Exceptions to issues raised by Northern States Power Company on May 31, 2005. On April 19, 2005, the FERC issued its Order on Compliance Filing and Motion for Refunds. In this Order, the FERC approved Williston Basin's refund rates and established rates to be effective April 19, 2005. Williston Basin filed its compliance filing complying with the requirements of this Order regarding rates and issued refunds totaling approximately $18.5 million to its customers on May 19, 2005. Williston Basin filed its Refund Report, detailing the $18.5 million in refunds it issued to its customers, with the FERC on June 1, 2005. As a result of the Order, Williston Basin recorded a $5.0 million (after tax) benefit from the resolution of the rate proceeding.

19. Contingencies

Litigation

In June 1997, Jack J. Grynberg (Grynberg) filed suit under the Federal False Claims Act against Williston Basin and Montana- Dakota and filed over 70 similar suits against natural gas transmission companies and producers, gatherers, and processors of natural gas. Grynberg, acting on behalf of the United States under the Federal False Claims Act, alleged improper measurement of the heating content and volume of natural gas purchased by the defendants resulting in the underpayment of royalties to the United States. In April 1999, the United States Department of Justice decided not to intervene in these cases. In response to a motion filed by Grynberg, the Judicial Panel on Multidistrict Litigation consolidated all of these cases in the United States District Court for the District of Wyoming (Wyoming Federal District Court).

In June 2004, following preliminary discovery, Williston Basin and Montana-Dakota joined with other defendants and filed a Motion to Dismiss on the ground that the information upon which Grynberg based his complaint was publicly disclosed prior to the filing of his complaint and further, that he is not the original source of such information. The Motion to Dismiss is additionally based on the ground that Grynberg disclosed the filing of the complaint prior to the entry of a court order allowing such disclosure and that Grynberg failed to provide adequate information to the government prior to filing suit. The Motion to Dismiss was heard on March 17 and 18, 2005, by the Special Master appointed by the Wyoming Federal District Court. The Special Master, in his Written Report dated May 13, 2005, recommended the dismissal of Williston Basin and Montana- Dakota. The Written Report will be considered for adoption by the Wyoming Federal District Court.

In the event the Motion to Dismiss is not granted, it is expected that further discovery will follow. Williston Basin and Montana-Dakota believe Grynberg will not prevail in the suit or recover damages from Williston Basin and/or Montana- Dakota because insufficient facts exist to support the allegations. Williston Basin and Montana-Dakota believe Grynberg's claims are without merit and intend to vigorously contest this suit.

Grynberg has not specified the amount he seeks to recover. Williston Basin and Montana-Dakota are unable to estimate their potential exposure and will be unable to do so until discovery is completed.

Fidelity has been named as a defendant in, and/or certain of its operations are or have been the subject of, more than a dozen lawsuits filed in connection with its coalbed natural gas development in the Powder River Basin in Montana and Wyoming. These lawsuits were filed in federal and state courts in Montana between June 2000 and November 2004 by a number of environmental organizations, including the Northern Plains Resource Council (NPRC) and the Montana Environmental Information Center, as well as the Tongue River Water Users' Association and the Northern Cheyenne Tribe. Portions of two of the lawsuits have been transferred to the Wyoming Federal District Court. The lawsuits involve allegations that Fidelity and/or various government agencies are in violation of state and/or federal law, including the Federal Clean Water Act, the National Environmental Policy Act (NEPA), the Federal Land Management Policy Act, the National Historic Preservation Act (NHPA) and the Montana Environmental Policy Act. The cases involving alleged violations of the Federal Clean Water Act have been resolved without a finding that Fidelity is in violation of the Federal Clean Water Act. There presently are no claims pending for penalties, fines or damages under the Federal Clean Water Act. The suits that remain extant include a variety of claims that state and federal government agencies violated various environmental laws that impose procedural requirements and the lawsuits seek injunctive relief, invalidation of various permits and unspecified damages.

In suits filed in the United States District Court for the District of Montana (Montana Federal District Court), the NPRC and the Northern Cheyenne Tribe asserted that further development by Fidelity and others of coalbed natural gas in Montana should be enjoined until the Bureau of Land Management (BLM) completes a Supplemental Environmental Impact Statement (SEIS). The Montana Federal District Court, in February 2005, entered a ruling requiring the BLM to complete a SEIS. The Montana Federal District Court later entered an order that would have allowed limited coalbed natural gas production in the Powder River Basin in Montana pending the BLM's preparation of the SEIS. The plaintiffs appealed the decision to the United States Ninth Circuit Court of Appeals (Ninth Circuit). The Montana Federal District Court declined to enter an injunction requested by the NPRC and the Northern Cheyenne Tribe that would have enjoined production pending the appeal. In late May 2005, the Ninth Circuit granted the request of the NPRC and the Northern Cheyenne Tribe and, pending further order from the Ninth Circuit, enjoined the BLM from approving any coalbed natural gas production projects in the Powder River Basin in Montana. That court also enjoined Fidelity from drilling any additional federally permitted wells in its Montana Coal Creek Project and from constructing infrastructure to produce and transport coalbed natural gas from the Coal Creek Project's existing federal wells.

In related actions in the Montana Federal District Court, the NPRC and the Northern Cheyenne Tribe asserted (among other things) that the actions of the BLM in approving Fidelity's applications for permits and the plan of development for the Tongue River-Badger Hills Project in Montana (Badger Hills Project) did not comply with applicable Federal laws, including the NHPA and the NEPA. The NPRC also asserted that the Environmental Assessment that supported the BLM's prior approval of the Badger Hills Project was invalid. On June 6, 2005, the Montana Federal District Court issued orders in these cases enjoining operations on Fidelity's Badger Hills Project pending the BLM's consultation with the Northern Cheyenne Tribe as to satisfaction of the applicable requirements of NHPA and a further environmental analysis under NEPA. Fidelity has sought and obtained stays of the injunctive relief from the Montana Federal District Court and production from Fidelity's Badger Hills Project continues.

Fidelity is vigorously defending all coalbed-related lawsuits and related actions in which it is involved, including the recent Ninth Circuit and Montana Federal District Court injunctions. In those cases where damage claims have been asserted, Fidelity is unable to quantify the damages sought and will be unable to do so until after the completion of discovery. If the plaintiffs are successful in these lawsuits, the ultimate outcome of the actions could have a material effect on Fidelity's existing coalbed natural gas operations and/or the future development of this resource in the affected regions.

Montana-Dakota has joined with two electric generators in appealing a finding by the North Dakota Department of Health (ND Health Department) in September 2003 that the ND Health Department may unilaterally revise operating permits previously issued to electric generating plants. Although it is doubtful that any revision of Montana-Dakota's operating permits by the ND Health Department would reduce the amount of electricity its plants could generate, the finding, if allowed to stand, could increase costs for sulfur dioxide removal and/or limit Montana- Dakota's ability to modify or expand operations at its North Dakota generation sites. Montana-Dakota and the other electric generators filed their appeal of the order in October 2003, in the Burleigh County District Court in Bismarck, North Dakota. Proceedings have been stayed pending discussions with the U.S. Environmental Protection Agency (EPA), the ND Health Department and the other electric generators.

The Company is also involved in other legal actions in the ordinary course of its business. Although the outcomes of any such legal actions cannot be predicted, management believes that the outcomes with respect to these other legal proceedings will not have a material adverse effect upon the Company's financial position or results of operations.

Environmental matters

In December 2000, Morse Bros., Inc. (MBI), an indirect wholly owned subsidiary of the Company, was named by the EPA as a Potentially Responsible Party in connection with the cleanup of a commercial property site, acquired by MBI in 1999, and part of the Portland, Oregon, Harbor Superfund Site. Sixty-eight other parties were also named in this administrative action. The EPA wants responsible parties to share in the cleanup of sediment contamination in the Willamette River. To date, costs of the overall remedial investigation of the harbor site for both the EPA and the Oregon State Department of Environmental Quality (DEQ) are being recorded, and initially paid, through an administrative consent order by the Lower Willamette Group (LWG), a group of 10 entities, which does not include MBI. The LWG estimates the overall remedial investigation and feasibility study will cost approximately $10 million. It is not possible to estimate the cost of a corrective action plan until the remedial investigation and feasibility study has been completed, the EPA has decided on a strategy, and a record of decision has been published. While the remedial investigation and feasibility study for the harbor site has commenced, it is expected to take several years to complete. The development of a proposed plan and record of decision on the harbor site is not anticipated to occur until 2006, after which a cleanup plan will be undertaken.

Based upon a review of the Portland Harbor sediment contamination evaluation by the DEQ and other information available, MBI does not believe it is a Responsible Party. In addition, MBI has notified Georgia-Pacific West, Inc., the seller of the commercial property site to MBI, that it intends to seek indemnity for any and all liabilities incurred in relation to the above matters, pursuant to the terms of their sale agreement.

The Company believes it is not probable that it will incur any material environmental remediation costs or damages in relation to the above administrative action.

In August 2004, Colorado Power Partners (CPP) and BIV Generation Company, LLC (BIV), indirect wholly owned subsidiaries of the Company, were each issued a draft Compliance Order on Consent (Compliance Orders) by the Colorado Department of Public Health and Environment (CDPHE). The Compliance Orders were issued in connection with excess emission periods of nitrogen oxides and carbon monoxide at the Company's electric generating facilities in Brush, Colorado, occurring mainly during start-up and shut-down periods. In June 2005, CPP, BIV and the CDPHE agreed upon the Compliance Orders. The terms of the Compliance Orders for CPP and BIV include administrative penalties of $9,900 and $10,600, and noncompliance/economic benefit penalties of $7,700 and $8,300, respectively. In addition, the terms of the Compliance Orders include an agreement for CPP and BIV to make a non-tax deductible donation for a Supplemental Environmental Project (SEP) in Morgan County, Colorado with total expenditures of not less than $39,600 and $42,400, respectively. If the parties cannot come to an agreement on the SEP to be funded within 120 days of the Compliance Order, CPP and BIV shall pay $39,600 and $42,400, respectively, as administrative penalties.

Guarantees

Centennial had unconditionally guaranteed a portion of certain bank borrowings of MPX in connection with the Company's equity method investment in the Termoceara Generating Facility, as discussed in Note 12. The Company, through an indirect wholly owned subsidiary, owned 49 percent of MPX. The guarantee to MPX's creditors expired on July 25, 2005, as the outstanding bank borrowings were repaid on that date. At June 30, 2005, the aggregate amount of borrowings outstanding subject to these guarantees was $29.6 million. These guarantees are not reflected on the Consolidated Balance Sheets.

In connection with the sale of MPX to Petrobras an indirect wholly-owned subsidiary of the Company has agreed to indemnify Petrobras for 49 percent of any losses which Petrobras may incur from certain contingent liabilities specified in the purchase agreement. Centennial has agreed to unconditionally guarantee payment of the indemnity obligations to Petrobras.

In addition, WBI Holdings has guaranteed certain of Fidelity's natural gas and oil price swap and collar agreement obligations. Fidelity's obligations at June 30, 2005, were $11.3 million. There is no fixed maximum amount guaranteed in relation to the natural gas and oil price swap and collar agreements, as the amount of the obligation is dependent upon natural gas and oil commodity prices. The amount of hedging activity entered into by the subsidiary is limited by corporate policy. The guarantees of the natural gas and oil price swap and collar agreements at June 30, 2005, expire in 2005 and 2006; however, Fidelity continues to enter into additional hedging activities and, as a result, WBI Holdings from time to time may issue additional guarantees on these hedging obligations. The amount outstanding by Fidelity was reflected on the Consolidated Balance Sheets at June 30, 2005. In the event Fidelity defaults under its obligations, WBI Holdings would be required to make payments under its guarantees.

Certain subsidiaries of the Company have outstanding guarantees to third parties that guarantee the performance of other subsidiaries of the Company. These guarantees are related to natural gas transportation and sales agreements, electric power supply agreements, insurance policies and certain other guarantees. At June 30, 2005, the fixed maximum amounts guaranteed under these agreements aggregated $99.3 million. The amounts of scheduled expiration of the maximum amounts guaranteed under these agreements aggregate $15.0 million in 2005; $27.4 million in 2006; $2.2 million in 2007; $200,000 in 2008; $900,000 in 2009; $30.0 million in 2010; $12.0 million in 2012; $2.1 million in 2028; $500,000, which is subject to expiration 30 days after the receipt of written notice and $9.0 million, which has no scheduled maturity date. A guarantee for an unfixed amount estimated at $300,000 at June 30, 2005, has no scheduled maturity date. The amount outstanding by subsidiaries of the Company under the above guarantees was $528,000 and was reflected on the Consolidated Balance Sheets at June 30, 2005. In the event of default under these guarantee obligations, the subsidiary issuing the guarantee for that particular obligation would be required to make payments under its guarantee.

Fidelity and WBI Holdings have outstanding guarantees to Williston Basin. These guarantees are related to natural gas transportation and storage agreements that guarantee the performance of Prairielands Energy Marketing, Inc. (Prairielands), an indirect wholly owned subsidiary of the Company. At June 30, 2005, the fixed maximum amounts guaranteed under these agreements aggregated $22.9 million. Scheduled expiration of the maximum amounts guaranteed under these agreements aggregate $2.9 million in 2008 and $20.0 million in 2009. In the event of Prairielands' default in its payment obligations, the subsidiary issuing the guarantee for that particular obligation would be required to make payments under its guarantee. The amount outstanding by Prairielands under the above guarantees was $1.5 million, which was not reflected on the Consolidated Balance Sheet at June 30, 2005, because these intercompany transactions are eliminated in consolidation.

In addition, Centennial has issued guarantees to third parties related to the Company's routine purchase of maintenance items for which no fixed maximum amounts have been specified. These guarantees have no scheduled maturity date. In the event a subsidiary of the Company defaults under its obligation in relation to the purchase of certain maintenance items, Centennial would be required to make payments under these guarantees. Any amounts outstanding by subsidiaries of the Company for these maintenance items were reflected on the Consolidated Balance Sheet at June 30, 2005.

As of June 30, 2005, Centennial was contingently liable for the performance of certain of its subsidiaries under approximately $614 million of surety bonds. These bonds are principally for construction contracts and reclamation obligations of these subsidiaries entered into in the normal course of business. Centennial indemnifies the respective surety bond companies against any exposure under the bonds. The purpose of Centennial's indemnification is to allow the subsidiaries to obtain bonding at competitive rates. In the event a subsidiary of the Company does not fulfill its obligations in relation to its bonded contract or obligation, Centennial may be required to make payments under its indemnification. A large portion of these contingent commitments is expected to expire within the next 12 months; however, Centennial will likely continue to enter into surety bonds for its subsidiaries in the future. The surety bonds were not reflected on the Consolidated Balance Sheets.

20. Related party transactions

In 2004, Bitter Creek Pipelines, LLC (Bitter Creek), an indirect wholly owned subsidiary of the Company, entered into two natural gas gathering agreements with Nance Petroleum Corporation (Nance Petroleum), a wholly owned subsidiary of St. Mary Land & Exploration Company (St. Mary). Robert L. Nance, an executive officer and shareholder of St. Mary, is also a member of the Board of Directors of the Company. The natural gas gathering agreements with Nance Petroleum were effective upon completion of certain high and low pressure gathering facilities, which occurred in mid-December 2004. Bitter Creek's capital expenditures related to the completion of the gathering lines and the expansion of its gathering facilities to accommodate the natural gas gathering agreements were $1.1 million and $2.1 million for the three and six months ended June 30, 2005, respectively, and are estimated for the next three years to be $3.2 million in 2005, $2.2 million in 2006 and $3.3 million in 2007. The natural gas gathering agreements are each for a term of 15 years and month-to-month thereafter. Bitter Creek's revenues from these contracts were $287,000 and $539,000 for the three and six months ended June 30, 2005, respectively, and estimated revenues from these contracts for the next three years are $1.8 million in 2005, $4.3 million in 2006 and $6.0 million in 2007. The amount due from Nance Petroleum at June 30, 2005, was $98,000.

Montana-Dakota entered into an agreement to purchase natural gas from Nance Petroleum for the period April 1, 2005 to October 31, 2005. Montana-Dakota estimates that it will purchase between $2.0 million to $2.5 million of natural gas from Nance Petroleum during this period. Montana-Dakota's expenses under this agreement for the three and six months ended June 30, 2005, were $760,000. The amount due to Nance Petroleum at June 30, 2005, was $251,000.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

This subsection of MD&A is an overview of the important factors that management focuses on in evaluating the Company's businesses, the Company's financial condition and operating performance, the Company's overall business strategy and the earnings of the Company for the period covered by this report. This subsection is not intended to be a substitute for reading the entire MD&A section. Reference is made to the various important factors listed under the heading Risk Factors and Cautionary Statements that May Affect Future Results, as well as other factors that are listed in the Introduction in relation to any forward-looking statement.

Business and Strategy Overview

Prior to the fourth quarter of 2004, the Company reported six reportable segments consisting of electric, natural gas distribution, utility services, pipeline and energy services, natural gas and oil production and construction materials and mining. The independent power production and other operations did not individually meet the criteria to be considered a reportable segment. In the fourth quarter of 2004, the Company separated independent power production as a reportable business segment due to the significance of its operations. The Company's operations are now conducted through seven reportable segments and all prior period information has been restated to reflect this change.

The vast majority of the Company's operations are located within the United States. The Company also has investments in foreign countries, which consist of investments in natural resource-based projects, as discussed in Note 12 of Notes to Consolidated Financial Statements.

The electric segment includes the electric generation, transmission and distribution operations of Montana-Dakota. The natural gas distribution segment includes the natural gas distribution operations of Montana-Dakota and Great Plains Natural Gas Co. The electric and natural gas distribution segments also supply related value-added products and services in the northern Great Plains.

The utility services segment includes all the operations of Utility Services, Inc., which specializes in electrical line construction, pipeline construction, inside electrical wiring and cabling, and the manufacture and distribution of specialty equipment.

The pipeline and energy services segment includes WBI Holdings' natural gas transportation, underground storage and gathering services through regulated and nonregulated pipeline systems primarily in the Rocky Mountain and northern Great Plains regions of the United States. The pipeline and energy services segment also provides energy-related management services, including cable and pipeline magnetization and locating.

The natural gas and oil production segment includes WBI Holdings' natural gas and oil acquisition, exploration, development and production operations, primarily in the Rocky Mountain region of the United States and in and around the Gulf of Mexico.

The construction materials and mining segment includes the results of Knife River, which mines aggregates and markets crushed stone, sand, gravel and related construction materials, including ready- mixed concrete, cement, asphalt and other value-added products, as well as performs integrated construction services, in the central and western United States and in the states of Alaska and Hawaii.

The independent power production operations of Centennial Resources own, build and operate electric generating facilities in the United States and have investments in domestic and international natural resource-based projects. Electric capacity and energy produced at its power plants are sold primarily under mid- and long-term contracts to nonaffiliated entities.

Earnings (loss) from electric, natural gas distribution and pipeline and energy services are substantially all from regulated operations. Earnings (loss) from utility services, natural gas and oil production, construction materials and mining, independent power production, and other are all from nonregulated operations.

The Company's strategy is to apply its expertise in energy and transportation infrastructure industries to increase market share through internal growth along with acquisition of well-managed companies and properties, and development of projects that enhance shareholder value and are accretive to earnings per share and returns on invested capital.

The Company has capabilities to fund its growth and operations through various sources, including internally generated funds, commercial paper credit facilities and through the issuance of long- term debt and the Company's equity securities. Net capital expenditures are estimated to be approximately $700 million for 2005.

The Company faces certain challenges and risks as it pursues its growth strategies, including, but not limited to the following:

- The natural gas and oil production business experiences fluctuations in natural gas and oil prices. These prices are volatile and subject to significant change at any time. The Company hedges a portion of its natural gas and oil production in order to mitigate the effects of price volatility.

- Economic volatility both domestically and in the foreign countries where the Company does business affects the Company's operations as well as the demand for its products and services and, as a result, may have a negative impact on the Company's future revenues.

- Fidelity continues to seek additional reserve and production growth, both in areas of existing activity and in other regions, through acquisition, exploration, development and production of natural gas and oil resources, including the development and production of its coalbed natural gas properties in the Powder River Basin. In this context, Fidelity has been named as a defendant in, and/or certain of its operations are the subject of, more than a dozen lawsuits filed in connection with its coalbed natural gas development program. Some of these actions have been successfully resolved and Fidelity is actively defending the others. If the plaintiffs are successful in the outstanding lawsuits, the ultimate outcome of the actions could have a material effect on Fidelity's existing coalbed natural gas operations and/or the future development of its coalbed natural gas properties in this region.

For further information on certain factors that should be considered for a better understanding of the Company's financial condition, see the various important factors listed under the heading Risk Factors and Cautionary Statements that May Affect Future Results, as well as other factors that are listed in the Introduction.

For information pertinent to various commitments and contingencies, see Notes to Consolidated Financial Statements.

________________________________

Three Months Ended June 30, 2005 and 2004

Consolidated earnings for the second quarter ended June 30, 2005, increased $21.5 million largely due to:

- A $15.6 million benefit from the sale of the Termoceara Generating Facility, partially offset by the absence in 2005 of the 2004 operating results from the Termoceara Generating Facility at the independent power production business
- Increased outside electrical line construction and inside electrical workloads and margins at the utility services business
- A $5.0 million (after tax) benefit from the resolution of a rate proceeding, as discussed in Note 18 of Notes to Consolidated Financial Statements at the pipeline and energy services business
- Higher natural gas prices of 19 percent and higher oil prices of 29 percent at the natural gas and oil production business

Partially offsetting the increase was the absence of the favorable resolution of federal and related state income tax matters, which resulted in a benefit of $5.9 million (after tax), including interest, for the three months ended June 30, 2004.

Six Months Ended June 30, 2005 and 2004

Consolidated earnings for the six months ended June 30, 2005, increased $32.4 million largely due to:

- Increased outside electrical line construction and inside electrical workloads and margins at the utility services business
- Higher natural gas prices of 14 percent and higher oil prices of 28 percent at the natural gas and oil production business
- A $15.6 million benefit from the sale of the Termoceara Generating Facility, partially offset by the absence in 2005 of the 2004 operating results from the Termoceara Generating Facility at the independent power production business
- A $5.0 million (after tax) benefit from the resolution of a rate proceeding, as previously discussed

Partially offsetting the increase was the absence of the favorable resolution of federal and related state income tax matters realized in 2004.

Three Months Ended June 30, 2005 and 2004

Electric earnings increased $1.1 million due to:

- Increased retail sales margins, largely the result of a 10 percent increase in retail sales volumes
- Increased sales for resale margins of $400,000 (after tax), due to lower fuel costs which were partially offset by a 32 percent decrease in sales for resale volumes
- Lower interest expense of $300,000 (after tax)

The increase in earnings was partially offset by the absence of the favorable resolution of federal and related state income tax matters realized in 2004 of $1.2 million (after tax), including interest.

Six Months Ended June 30, 2005 and 2004

Electric earnings increased $700,000 due to:

- Decreased operation and maintenance expense of $600,000 (after tax)
- Higher retail sales margins, largely due to higher volumes
- Higher sales for resale margins, primarily the result of higher average realized prices of 11 percent and lower purchased power- related costs, offset in part by decreased sales for resale volumes of 21 percent
- Lower net interest expense of $500,000 (after tax)

Partially offsetting the increase in earnings was the absence of the favorable resolution of federal and related state income tax matters realized in 2004 of $1.2 million (after tax), including interest.

Three Months Ended June 30, 2005 and 2004

The natural gas and oil production business experienced an increase in earnings of $3.7 million due to:

- Higher average realized natural gas prices of 19 percent
- Higher average realized oil prices of 29 percent

Partially offsetting the increase were:

- Higher depreciation, depletion and amortization expense of $2.0 million (after tax) due to higher rates, largely driven by a recent acquisition
- Decreased oil production volumes of 10 percent, due in part to normal production declines, offset in part by production from an acquisition made in the second quarter of 2005
- Decreased natural gas production of 1 percent, primarily due to normal production declines and timing-related delays affecting coalbed natural gas drilling activity as a result of ongoing environmental litigation, largely offset by increased production from natural gas properties in the Rocky Mountain region and production from an acquisition made in the second quarter of 2005

Six Months Ended June 30, 2005 and 2004

Natural gas and oil production earnings increased $7.4 million due to:

- Higher average realized natural gas prices of 14 percent
- Higher average realized oil prices of 28 percent

Partially offsetting the increase were:

- Decreased oil production of 15 percent, primarily due to normal production declines, offset in part by production from an acquisition made in the second quarter of 2005
- Higher depreciation, depletion and amortization expense of $2.4 million (after tax) due to higher rates
- Lower natural gas production of 1 percent, primarily due to normal production declines and timing-related delays affecting coalbed natural gas drilling activity as a result of ongoing environmental litigation, largely offset by increased production from natural gas properties in the Rocky Mountain region and production from an acquisition made in the second quarter of 2005

Construction materials and mining had $18.4 million in earnings for the second quarter of 2005 compared to $20.4 million in the comparable prior period. The $2.0 million decrease in earnings was due to:

- The absence in 2005 of the 2004 favorable resolution of federal and related state income tax matters of $1.2 million (after tax), including interest
- Increased depreciation, depletion and amortization expenses of $1.0 million (after tax) due to higher property, plant and equipment balances
- The effects of unfavorable weather on asphalt and construction volumes and margins

Partially offsetting the decline were increased ready-mixed concrete margins.

Six Months Ended June 30, 2005 and 2004

Earnings at the construction materials and mining business increased $1.4 million due to:

- Increased ready-mixed concrete volumes and margins
- Higher cement volumes
- Earnings from companies acquired since the comparable prior period, which contributed approximately 6 percent of earnings

Partially offsetting the increase were:

- Higher depreciation, depletion and amortization expenses, the result of higher property, plant and equipment balances
- Lower asphalt volumes and margins due largely to effects of weather and higher fuel prices
- The absence in 2005 of the 2004 favorable resolution of federal and related state income tax matters of $1.2 million (after tax), including interest

RISK FACTORS AND CAUTIONARY STATEMENTS THAT MAY AFFECT FUTURE RESULTS

The Company is including the following factors and cautionary statements in this Form 10-Q to make applicable and to take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 for any forward-looking statements made by, or on behalf of, the Company. Forward-looking statements include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions (many of which are based, in turn, upon further assumptions) and other statements that are other than statements of historical facts. From time to time, the Company may publish or otherwise make available forward-looking statements of this nature, including statements contained within Prospective Information. All these subsequent forward-looking statements, whether written or oral and whether made by or on behalf of the Company, are also expressly qualified by these factors and cautionary statements.

Forward-looking statements involve risks and uncertainties, which could cause actual results or outcomes to differ materially from those expressed. The Company's expectations, beliefs and projections are expressed in good faith and are believed by the Company to have a reasonable basis, including without limitation, management's examination of historical operating trends, data contained in the Company's records and other data available from third parties. Nonetheless, the Company's expectations, beliefs or projections may not be achieved or accomplished.

Any forward-looking statement contained in this document speaks only as of the date on which the statement is made, and the Company undertakes no obligation to update any forward-looking statement or statements to reflect events or circumstances that occur after the date on which the statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for management to predict all of the factors, nor can it assess the effect of each factor on the Company's business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statement.

Following are some specific factors that should be considered for a better understanding of the Company's financial condition. These factors and the other matters discussed herein are important factors that could cause actual results or outcomes for the Company to differ materially from those discussed in the forward-looking statements included elsewhere in this document.

Economic Risks

The Company's natural gas and oil production and pipeline and energy services businesses are dependent on factors, including commodity prices and commodity price basis differentials, which cannot be predicted or controlled.

These factors include: price fluctuations in natural gas and crude oil prices; fluctuations in commodity price basis differentials; availability of economic supplies of natural gas; drilling successes in natural gas and oil operations; the timely receipt of necessary permits and approvals; the ability to contract for or to secure necessary drilling rig contracts and to retain employees to drill for and develop reserves; the ability to acquire natural gas and oil properties; and other risks incidental to the operations of natural gas and oil wells. Significant changes in these factors could negatively affect the results of operations and financial condition of the Company's natural gas and oil production and pipeline and energy services businesses.

The construction and operation of power generation facilities may involve unanticipated changes or delays that could negatively impact the Company's business and its results of operations.

The construction and operation of power generation facilities involves many risks, including start-up risks, breakdown or failure of equipment, competition, inability to obtain required governmental permits and approvals, and inability to negotiate acceptable acquisition, construction, fuel supply, off-take, transmission or other material agreements, as well as the risk of performance below expected levels of output or efficiency. Such unanticipated events could negatively impact the Company's business and its results of operations.

The Company's utility services business operates in highly competitive markets characterized by low margins in a number of service lines and geographic areas.

This business' ability to continue its return to profitability on a sustained basis will depend upon improved capital spending for electric construction services and continuing success in management's ability to refocus the business on more profitable markets, reduce operating costs and implement process improvements in project management.

Economic volatility affects the Company's operations as well as the demand for its products and services and, as a result, may have a negative impact on the Company's future revenues.

The global demand for natural resources, interest rates, governmental budget constraints, and the ongoing threat of terrorism can create volatility in the financial markets. A soft economy could negatively affect the level of public and private expenditures on projects and the timing of these projects which, in turn, would negatively affect the demand for the Company's products and services.

The Company relies on financing sources and capital markets. If the Company is unable to obtain financing in the future, the Company's ability to execute its business plans, make capital expenditures or pursue acquisitions that the Company may otherwise rely on for future growth could be impaired.

The Company relies on access to both short-term borrowings, including the issuance of commercial paper, and long-term capital markets as a source of liquidity for capital requirements not satisfied by its cash flow from operations. If the Company is not able to access capital at competitive rates, the ability to implement its business plans may be adversely affected. Market disruptions or a downgrade of the Company's credit ratings may increase the cost of borrowing or adversely affect its ability to access one or more financial markets. Such disruptions could include:

- A severe prolonged economic downturn
- The bankruptcy of unrelated industry leaders in the same line of business
- A deterioration in capital market conditions
- Volatility in commodity prices
- Terrorist attacks
- Fluctuations in the value of the dollar on currency exchanges

Environmental and Regulatory Risks

Some of the Company's operations are subject to extensive environmental laws and regulations that may increase costs of operations, impact or limit business plans, or expose the Company to environmental liabilities.

The Company is subject to extensive environmental laws and regulations affecting many aspects of its present and future operations including air quality, water quality, waste management and other environmental considerations. These laws and regulations can result in increased capital, operating and other costs, and delays as a result of ongoing litigation and compliance, remediation, containment and monitoring obligations, particularly with regard to laws relating to power plant emissions and coalbed natural gas development. These laws and regulations generally require the Company to obtain and comply with a wide variety of environmental licenses, permits, inspections and other approvals. Public officials and entities, as well as private individuals and organizations, may seek injunctive relief or other remedies to enforce applicable environmental laws and regulations. The Company cannot predict the outcome (financial or operational) of any related litigation that may arise.

Existing environmental regulations may be revised and new regulations seeking to protect the environment may be adopted or become applicable to the Company. Revised or additional regulations, which result in increased compliance costs or additional operating restrictions, particularly if those costs are not fully recoverable from customers, could have a material effect on the Company's results of operations.

One of the Company's subsidiaries is subject to litigation in connection with its coalbed natural gas development activities. These proceedings have caused delays in coalbed natural gas drilling activity in 2005, and the ultimate outcome of the actions could have a material effect on existing coalbed natural gas operations and/or the future development of its coalbed natural gas properties.

Fidelity has been named as a defendant in, and/or certain of its operations are the subject of, a number of lawsuits filed in connection with its coalbed natural gas development in the Powder River Basin in Montana and Wyoming. Injunctive orders issued by the Ninth Circuit and the Montana Federal District Court have occasioned reductions in Fidelity's estimated total 2005 natural gas production levels. If the plaintiffs are successful in these lawsuits, the ultimate outcome of the actions could have a material effect on Fidelity's existing coalbed natural gas operations and/or the future development of its coalbed natural gas properties.

The Company is subject to extensive government regulations that may delay and/or have a negative impact on its business and its results of operations.

The Company is subject to regulation by federal, state and local regulatory agencies with respect to, among other things, allowed rates of return, financings, industry rate structures, and recovery of purchased power and purchased gas costs. These governmental regulations significantly influence the Company's operating environment and may affect its ability to recover costs from its customers. The Company is unable to predict the impact on operating results from the future regulatory activities of any of these agencies.

Changes in regulations or the imposition of additional regulations could have an adverse impact on the Company's results of operations.

Risks Relating to Foreign Operations

The value of the Company's investments in foreign operations may diminish due to political, regulatory and economic conditions in countries where the Company does business.

The Company is subject to political, regulatory and economic conditions in foreign countries where the Company does business. Significant changes in the political, regulatory or economic environment in these countries could negatively affect the value of the Company's investments located in these countries.

Other Risks

Competition is increasing in all of the Company's businesses.

All of the Company's businesses are subject to increased competition. The independent power production industry includes many strong and capable competitors, some of which have greater resources and more experience in the operation, acquisition and development of power generation facilities. Utility services' competition is based primarily on price and reputation for quality, safety and reliability. The construction materials products are marketed under highly competitive conditions and are subject to such competitive forces as price, service, delivery time and proximity to the customer. The electric utility and natural gas industries are also experiencing increased competitive pressures as a result of consumer demands, technological advances, deregulation, greater availability of natural gas-fired generation and other factors. Pipeline and energy services competes with several pipelines for access to natural gas supplies and gathering, transportation and storage business. The natural gas and oil production business is subject to competition in the acquisition and development of natural gas and oil properties as well as in the sale of its production output. The increase in competition could negatively affect the Company's results of operations and financial condition.

Weather conditions can adversely affect the Company's operations and revenues.

The Company's results of operations can be affected by changes in the weather. Weather conditions directly influence the demand for electricity and natural gas, affect the wind-powered operation at the independent power production business, affect the price of energy commodities, affect the ability to perform services at the utility services and construction materials and mining businesses and affect ongoing operation and maintenance and construction and drilling activities for the pipeline and energy services and natural gas and oil production businesses. In addition, severe weather can be destructive, causing outages, reduced natural gas and oil production, and/or property damage, which could require additional costs to be incurred. As a result, adverse weather conditions could negatively affect the Company's results of operations and financial condition.

PROSPECTIVE INFORMATION

The following information includes highlights of the key growth strategies, projections and certain assumptions for the Company and its subsidiaries and other matters for each of the Company's businesses. Many of these highlighted points are forward-looking statements. There is no assurance that the Company's projections, including estimates for growth and increases in revenues and earnings, will in fact be achieved. Reference is made to assumptions contained in this section, as well as the various important factors listed under the heading Risk Factors and Cautionary Statements that May Affect Future Results, and other factors that are listed in the Introduction. Changes in such assumptions and factors could cause actual future results to differ materially from targeted growth, revenue and earnings projections.

MDU Resources Group, Inc.

- Earnings per common share for 2005, diluted, are projected in the range of $1.90 to $2.10, an increase from prior guidance of $1.80 to $2.00.

- The Company expects the percentage of 2005 earnings per common share, diluted, by quarter to be in the following approximate ranges:

- Third quarter - 30 percent to 35 percent
- Fourth quarter - 18 percent to 23 percent

- The Company's long-term compound annual growth goals on earnings per share from operations are in the range of 7 percent to 10 percent.

- The Company anticipates investing approximately $700 million in capital expenditures during 2005.

Electric

- The expected earnings in 2005 are anticipated to be slightly lower than 2004.

- This segment is involved in the review of potential power projects to replace capacity associated with expiring purchased power contracts and to provide for future growth. Those projects include participation in a proposed 600-megawatt (MW) coal-fired facility to be located in northeastern South Dakota and construction of a 175-MW lignite coal-fired facility (Vision 21) to be located in southwestern North Dakota. The costs of building and/or acquiring the additional generating capacity needed by the utility are expected to be recovered in rates.

- Montana-Dakota has obtained and holds valid and existing franchises authorizing it to conduct its electric operations in all of the municipalities it serves where such franchises are required. Montana-Dakota intends to protect its service area and seek renewal of all expiring franchises.

- On October 25, 2004, Montana-Dakota issued a request for proposal for 70 megawatts to 100 megawatts of firm capacity and associated energy for the period of November 1, 2006 through December 31, 2010. Montana-Dakota is currently in the process of evaluating the responses. A decision is expected to be made late 2005.

Natural gas distribution

- The expected earnings for this segment for 2005 are projected to be significantly higher than the earnings for 2004.

- In September 2004, a natural gas rate case was filed with the MPUC requesting an increase of $1.4 million annually, or 4.0 percent. An interim increase of $1.4 million annually was approved by the MPUC effective January 10, 2005, subject to refund. A final order is expected in early 2006.

- In March 2005, a natural gas rate case was filed with the SDPUC for the East River service area requesting an increase of $850,000 annually, or 12.8 percent. A final order is expected in late 2005.

- Montana-Dakota and Great Plains have obtained and hold valid and existing franchises authorizing them to conduct their natural gas operations in all of the municipalities they serve where such franchises are required. Montana-Dakota and Great Plains intend to protect their service areas and seek renewal of all expiring franchises.

Utility services

- Revenues are expected to be in the range of $550 million to $600 million in 2005.

- The Company anticipates margins to increase substantially in 2005 as compared to 2004 levels.

- Work backlog as of June 30, 2005, was approximately $358 million, compared to $217 million at June 30, 2004.

Pipeline and energy services

- In 2005, total natural gas gathering and transportation throughput is expected to be down approximately 5 percent from the record levels achieved in 2004.

- Firm capacity for the Grasslands Pipeline is currently 90,000 Mcf per day with expansion possible to 200,000 Mcf per day.

- The labor contract that Williston Basin was negotiating, as reported in Items 1 and 2 - Business and Properties - General in the Company's 2004 Annual Report, remains in negotiations.

Natural gas and oil production

- The Company is expecting to drill approximately 300 wells in 2005.

- In 2005, the Company expects combined natural gas and oil production to approximate the record levels achieved in 2004, assuming continued production from existing wells at its Badger Hills Project in southeastern Montana. The Badger Hills Project has been the subject of two related actions filed in the Montana Federal District Court, in connection with which the Montana Federal District Court issued orders enjoining operations on the project. Subsequently, the Montana Federal District Court issued temporary stays of the injunction orders in these cases, thereby permitting continued production at the project pending further developments in the cases. Currently, this segment's net combined natural gas and oil production is approximately 200,000 Mcf equivalent to 210,000 Mcf equivalent per day.

- Estimates of natural gas prices in the Rocky Mountain region for August through December 2005 reflected in earnings guidance are in the range of $4.75 to $5.25 per Mcf. The Company's estimates for natural gas prices on the NYMEX for August through December 2005 reflected in earnings guidance are in the range of $5.75 to $6.25 per Mcf. During 2004, more than three-fourths of this segment's natural gas production was priced using Rocky Mountain or other non- NYMEX prices.

- Estimates of NYMEX crude oil prices for July through December 2005 reflected in earnings guidance are in the range of $45 to $50 per barrel.

- The Company has hedged a portion of its natural gas and oil production. The hedges that are in place as of July 20, 2005, for production in the last six months of 2005 and the twelve months of 2006 are summarized below:

Construction materials and mining

- The Company anticipates improved earnings in 2005 as compared to 2004 with an expected return to normal weather conditions in Texas, improved construction volumes and margins and earnings from acquisitions.

- Aggregate, asphalt and ready-mixed concrete volumes in 2005 are expected to be comparable to 2004 levels.

- Revenues in 2005 are expected to be approximately 5 percent to 10 percent higher than 2004 levels.

- The Company expects that the replacement funding legislation for the Transportation Equity Act for the 21st Century (TEA-21) will be equal to or higher than previous funding levels.

- Work backlog as of June 30, 2005, was approximately $740 million, compared to $545 million at June 30, 2004.

- The labor contract that Knife River was negotiating, as reported in Items 1 and 2 - Business and Properties - General in the Company's 2004 Annual Report, has been ratified.

Independent power production

- Earnings for 2005 are expected to be somewhat lower than 2004 earnings primarily due to benefits realized in 2004 from foreign currency gains and the effects of the embedded derivative in the Brazilian electric power sales contract, as well as the absence of ongoing earnings resulting from the Termoceara Generating Facility sale.

- The Company is constructing a 116-MW coal-fired electric generating facility near Hardin, Montana. A power sales agreement with Powerex Corp., a subsidiary of BC Hydro, has been secured for the entire output of the plant for a term expiring October 31, 2008, with the purchaser having an option for a two-year extension. The projected on-line date for this plant is late 2005.

NEW ACCOUNTING STANDARDS

SAB No. 106

In September 2004, the SEC issued SAB No. 106 which is an interpretation regarding the application of SFAS No. 143 by oil and gas producing companies following the full-cost accounting method. SAB No. 106 was effective for the Company as of January 1, 2005. The adoption of SAB No. 106 did not have a material effect on the Company's financial position or results of operations.

SFAS No. 123 (revised)

In December 2004, the FASB issued SFAS No. 123 (revised). SFAS No.
123 (revised) revises SFAS No. 123 and requires entities to recognize compensation expense in an amount equal to the fair value of share-based payments granted to employees. SFAS No. 123 (revised) requires a company to record compensation expense for all awards granted after the date of adoption of SFAS No. 123 (revised) and for the unvested portion of previously granted awards that remain outstanding at the date of adoption. SFAS No. 123 (revised) is effective for the Company on January 1, 2006. The Company is evaluating the effects of the adoption of SFAS No. 123 (revised).

FIN 47

In March 2005, the FASB issued FIN 47. FIN 47 addresses the diverse accounting practices that developed with respect to the timing of liability recognition for legal obligations associated with the retirement of a tangible long-lived asset when the timing and/or method of settlement of the obligation are conditional on a future event. FIN 47 is effective for the Company at the end of the fiscal year ending December 31, 2005. The Company is evaluating the effects of the adoption of FIN 47.

EITF No. 04-6

In March 2005, the FASB ratified EITF No. 04-6. EITF No. 04-6 requires that post-production stripping costs be treated as a variable inventory production cost. EITF No. 04-6 is effective for the Company on January 1, 2006. The Company is evaluating the effects of the adoption of EITF No. 04-6.

For further information on SAB No. 106, SFAS No. 123 (revised), FIN 47 and EITF No. 04-6, see Note 10 of Notes to Consolidated Financial Statements.

CRITICAL ACCOUNTING POLICIES INVOLVING SIGNIFICANT ESTIMATES

The Company's critical accounting policies involving significant estimates include impairment testing of long-lived assets and intangibles, impairment testing of natural gas and oil production properties, revenue recognition, purchase accounting, asset retirement obligations, and pension and other postretirement benefits. There were no material changes in the Company's critical accounting policies involving significant estimates from those reported in the 2004 Annual Report. For more information on critical accounting policies involving significant estimates, see

Part II, Item 7 in the 2004 Annual Report.

LIQUIDITY AND CAPITAL COMMITMENTS

Cash flows

Operating activities

Cash flows provided by operating activities in the first six months of 2005 decreased by $9.0 million from the comparable 2004 period, largely the result of a decrease in working capital of $43.8 million due in part to increased income tax payments. Partially offsetting the decrease was an increase in net income of $32.4 million.

Investing activities

Cash flows used in investing activities in the first six months of 2005 increased $212.6 million compared to the comparable 2004 period, primarily due to an increase in net capital expenditures (capital expenditures; acquisitions, net of cash acquired; and net proceeds from the sale or disposition of property) of $214.0 million due largely to acquisitions in the second quarter of 2005, the construction of a 116-megawatt coal-fired electric generating facility near Hardin, Montana and higher ongoing capital expenditures. Net capital expenditures exclude the noncash transactions related to acquisitions, including the issuance of the Company's equity securities. The noncash transactions were $30.6 million and $32.6 million for the six months ended June 30, 2005 and 2004, respectively.

Financing activities

Cash flows provided by financing activities in the first six months of 2005 increased by $133.8 million compared to the comparable 2004 period, largely the result of an increase in the issuance of long- term debt due in part to acquisitions in the second quarter of 2005 and the construction of a 116-megawatt coal-fired electric generating facility near Hardin, Montana. The increase was partially offset by an increase in the repayment of long-term debt of $81.5 million, partially due to the redemption of $20.9 million in Pollution Control Refunding Revenue bonds, and a $50.8 million decrease in the issuance of common stock as the result of proceeds received from an underwritten public offering in 2004.

Defined benefit pension plans

The Company has qualified noncontributory defined benefit pension plans (Pension Plans) for certain employees. Plan assets consist of investments in equity and fixed income securities. Various actuarial assumptions are used in calculating the benefit expense (income) and liability (asset) related to the Pension Plans. Actuarial assumptions include assumptions about the discount rate, expected return on plan assets and rate of future compensation increases as determined by the Company within certain guidelines. At December 31, 2004, certain Pension Plans' accumulated benefit obligations exceeded these plans' assets by approximately $3.7 million. Pretax pension expense (income) reflected in the years ended December 31, 2004, 2003 and 2002, was $4.1 million, $153,000, and ($2.4) million, respectively. The Company's pension expense is currently projected to be approximately $6.5 million to $7.5 million in 2005. A reduction in the Company's assumed discount rate for Pension Plans along with declines in the equity markets experienced in 2002 and 2001 have combined to largely produce the increase in these costs. Funding for the Pension Plans is actuarially determined. The minimum required contributions for 2004, 2003 and 2002 were approximately $1.2 million, $1.6 million, and $1.2 million, respectively.

For further information on the Company's Pension Plans, see Note 17 of Notes to Consolidated Financial Statements.

Capital expenditures

Net capital expenditures for the first six months of 2005 were $398.4 million. Net capital expenditures, including the issuance of the Company's equity securities in connection with acquisitions, are estimated to be approximately $700 million for the year 2005. Estimated capital expenditures include those for:

- Potential future acquisitions
- System upgrades
- Routine replacements
- Service extensions
- Routine equipment maintenance and replacements
- Buildings, land and building improvements
- Pipeline and gathering expansion projects
- Further enhancement of natural gas and oil production and reserve growth
- Power generation opportunities, including certain costs for additional electric generating capacity and for a 116-megawatt coal- fired development project, as previously discussed
- Other growth opportunities

Approximately 31 percent of estimated 2005 net capital expenditures are associated with completed and potential future acquisitions. The Company continues to evaluate potential future acquisitions and other growth opportunities; however, they are dependent upon the availability of economic opportunities and, as a result, capital expenditures may vary significantly from the estimated 2005 capital expenditures referred to previously. It is anticipated that all of the funds required for capital expenditures will be met from various sources, including internally generated funds; commercial paper credit facilities at Centennial and MDU Resources Group, Inc., as described below; and through the issuance of long-term debt and the Company's equity securities.

Capital resources

Certain debt instruments of the Company and its subsidiaries, including those discussed below, contain restrictive covenants, all of which the Company and its subsidiaries were in compliance with at June 30, 2005.

MDU Resources Group, Inc.

The Company has a revolving credit agreement with various banks totaling $100 million (with provision for an increase, at the option of the Company on stated conditions, up to a maximum of $125 million) at June 30, 2005. There were no amounts outstanding under the credit agreement at June 30, 2005. The credit agreement supports the Company's $75 million commercial paper program. There were no amounts outstanding under the Company's commercial paper program at June 30, 2005. The commercial paper borrowings classified as long-term debt are intended to be refinanced on a long- term basis through continued MDU Resources commercial paper borrowings and as further supported by the credit agreement, which expires in June 2010.

The Company's goal is to maintain acceptable credit ratings in order to access the capital markets through the issuance of commercial paper. If the Company were to experience a minor downgrade of its credit ratings, it would not anticipate any change in its ability to access the capital markets. However, in such event, the Company would expect a nominal basis point increase in overall interest rates with respect to its cost of borrowings. If the Company were to experience a significant downgrade of its credit ratings, which it does not currently anticipate, it may need to borrow under its credit agreement.

To the extent the Company needs to borrow under its credit agreement, it would be expected to incur increased annualized interest expense on its variable rate debt. This was not applicable at June 30, 2005, as there were no variable rate borrowings.

Prior to the maturity of the credit agreement, the Company plans to negotiate the extension or replacement of this agreement, which provides credit support to access the capital markets. In the event the Company is unable to successfully negotiate the credit agreement, or in the event the fees on this facility became too expensive, which it does not currently anticipate, the Company would seek alternative funding. One source of alternative funding might involve the securitization of certain Company assets.

In order to borrow under the Company's credit agreement, the Company must be in compliance with the applicable covenants and certain other conditions, including covenants not to permit, as of the end of any fiscal quarter, (A) the ratio of funded debt to total capitalization (determined on a consolidated basis) to be greater than 65 percent or (B) the ratio of funded debt to capitalization (determined with respect to the Company alone, excluding its subsidiaries) to be greater than 65 percent. Also included is a covenant that does not permit the ratio of the Company's earnings before interest, taxes, depreciation and amortization to interest expense (determined with respect to the Company alone, excluding its subsidiaries), for the twelve-month period ended each fiscal quarter, to be less than 2.5 to 1. Other covenants include limitation on sale of assets and limitation on investments. The Company was in compliance with these covenants and met the required conditions at June 30, 2005. In the event the Company does not comply with the applicable covenants and other conditions, alternative sources of funding may need to be pursued, as previously described.

There are no credit facilities that contain cross-default provisions between the Company and any of its subsidiaries.

The Company's issuance of first mortgage debt is subject to certain restrictions imposed under the terms and conditions of its Indenture of Mortgage. Generally, those restrictions require the Company to fund $1.43 of unfunded property or use $1.00 of refunded bonds for each dollar of indebtedness incurred under the Indenture and, in some cases, to certify to the trustee that annual earnings (pretax and before interest charges), as defined in the Indenture, equal at least two times its annualized first mortgage bond interest costs. Under the more restrictive of the tests, as of June 30, 2005, the Company could have issued approximately $350 million of additional first mortgage bonds.

The Company's coverage of fixed charges including preferred dividends was 5.4 times and 4.7 times for the twelve months ended June 30, 2005, and December 31, 2004, respectively. Additionally, the Company's first mortgage bond interest coverage was 9.3 times and 7.1 times for the twelve months ended June 30, 2005, and December 31, 2004, respectively. Common stockholders' equity as a percent of total capitalization (net of long-term debt due within one year) was 61 percent and 65 percent at June 30, 2005, and December 31, 2004, respectively.

Centennial Energy Holdings, Inc.

Centennial has three revolving credit agreements with various banks and institutions that support $331.4 million of Centennial's $350 million commercial paper program. There were no outstanding borrowings under the Centennial credit agreements at June 30, 2005. Under the Centennial commercial paper program, $300.8 million was outstanding at June 30, 2005. The Centennial commercial paper borrowings are classified as long-term debt as Centennial intends to refinance these borrowings on a long-term basis through continued Centennial commercial paper borrowings and as further supported by the Centennial credit agreements. One of these credit agreements is for $300 million and expires on August 17, 2007, and another agreement is for $21.4 million (previously $25 million) and expires on April 30, 2007. Pursuant to this credit agreement, on the last business day of April 2006, the line of credit will be reduced by $3.6 million. Centennial intends to negotiate the extension or replacement of these agreements prior to their maturities, and is currently in the process of negotiating the extension of the $300 million credit facility. The third agreement is an uncommitted line for $10 million, which was effective on January 25, 2005, and may be terminated by the bank at any time.

Centennial has an uncommitted long-term master shelf agreement that allows for borrowings of up to $450 million. Under the terms of the master shelf agreement, $388 million was outstanding at June 30, 2005. The ability to request additional borrowings under this master shelf agreement will expire in April 2008. To meet potential future financing needs, Centennial may pursue other financing arrangements, including private and/or public financing.

Centennial's goal is to maintain acceptable credit ratings in order to access the capital markets through the issuance of commercial paper. If Centennial were to experience a minor downgrade of its credit ratings, it would not anticipate any change in its ability to access the capital markets. However, in such event, Centennial would expect a nominal basis point increase in overall interest rates with respect to its cost of borrowings. If Centennial were to experience a significant downgrade of its credit ratings, which it does not currently anticipate, it may need to borrow under its committed bank lines.

To the extent Centennial needs to borrow under its committed bank lines, it would be expected to incur increased annualized interest expense on its variable rate debt of approximately $451,000 (after tax) based on June 30, 2005, variable rate borrowings. Based on Centennial's overall interest rate exposure at June 30, 2005, this change would not have a material effect on the Company's results of operations or cash flows.

Prior to the maturity of the Centennial credit agreements, Centennial plans to negotiate the extension or replacement of these agreements, which provide credit support to access the capital markets. In the event Centennial was unable to successfully negotiate these agreements, or in the event the fees on such facilities became too expensive, which Centennial does not currently anticipate, it would seek alternative funding. One source of alternative funding might involve the securitization of certain Centennial assets.

In order to borrow under Centennial's credit agreements and the Centennial uncommitted long-term master shelf agreement, Centennial and certain of its subsidiaries must be in compliance with the applicable covenants and certain other conditions including, covenants not to permit, as of the end of any fiscal quarter, the ratio of total debt to total capitalization to be greater than 60 percent. Also included is a covenant that does not permit the ratio of the Company's earnings before interest, taxes, depreciation and amortization to interest expense, for the twelve-month period ended each fiscal quarter, to be less than 2.25 to 1 (for the credit agreements) and 1.75 to 1 (for the master shelf agreement). Other covenants include minimum consolidated net worth, limitation on priority debt, limitation on sale of assets and limitation on loans and investments. Centennial and such subsidiaries were in compliance with these covenants and met the required conditions at June 30, 2005. In the event Centennial or such subsidiaries do not comply with the applicable covenants and other conditions, alternative sources of funding may need to be pursued as previously described.

Certain of Centennial's financing agreements contain cross-default provisions. These provisions state that if Centennial or any subsidiary of Centennial fails to make any payment with respect to any indebtedness or contingent obligation, in excess of a specified amount, under any agreement that causes such indebtedness to be due prior to its stated maturity or the contingent obligation to become payable, the applicable agreements will be in default. Certain of Centennial's financing agreements and Centennial's practice limit the amount of subsidiary indebtedness.

Williston Basin Interstate Pipeline Company

Williston Basin has an uncommitted long-term master shelf agreement that allows for borrowings of up to $100 million. Under the terms of the master shelf agreement, $55.0 million was outstanding at June 30, 2005. The ability to request additional borrowings under this master shelf agreement expires on December 20, 2005.

In order to borrow under Williston Basin's uncommitted long-term master shelf agreement, it must be in compliance with the applicable covenants and certain other conditions including, covenants not to permit, as of the end of any fiscal quarter, the ratio of total debt to total capitalization to be greater than 55 percent. Other covenants include limitation on priority debt, limitation on sale of assets and limitation on investments. Williston Basin was in compliance with these covenants and met the required conditions at June 30, 2005. In the event Williston Basin does not comply with the applicable covenants and other conditions, alternative sources of funding may need to be pursued.

Off balance sheet arrangements

Centennial had unconditionally guaranteed a portion of certain bank borrowings of MPX in connection with the Company's equity method investment in the Termoceara Generating Facility, as discussed in Note 12. The Company, through an indirect wholly owned subsidiary, owned 49 percent of MPX. The guarantee to MPX's creditors expired on July 25, 2005, as the outstanding bank borrowings were repaid on that date. At June 30, 2005, the aggregate amount of borrowings outstanding subject to these guarantees was $29.6 million.

As of June 30, 2005, Centennial was contingently liable for the performance of certain of its subsidiaries under approximately $614 million of surety bonds. These bonds are principally for construction contracts and reclamation obligations of these subsidiaries entered into in the normal course of business. Centennial indemnifies the respective surety bond companies against any exposure under the bonds. The purpose of Centennial's indemnification is to allow the subsidiaries to obtain bonding at competitive rates. In the event a subsidiary of the Company does not fulfill its obligations in relation to its bonded contract or obligation, Centennial may be required to make payments under its indemnification. A large portion of these contingent commitments is expected to expire within the next 12 months; however, Centennial will likely continue to enter into surety bonds for its subsidiaries in the future. The surety bonds were not reflected on the Consolidated Balance Sheets.

Contractual obligations and commercial commitments

There are no material changes in the Company's contractual obligations relating to operating leases and purchase commitments from those reported in the 2004 Annual Report.

The Company's long-term debt at June 30, 2005, increased $201.1 million or 21 percent from December 31, 2004 due in part to acquisitions in the second quarter of 2005 and the construction of a 116-megawatt coal-fired electric generating facility near Hardin, Montana. At June 30, 2005, the Company's long-term debt and estimated interest payments (for the twelve months ended June 30, of each year listed in the table below) were as follows:

                    2006   2007   2008   2009   2010  Thereafter    Total

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed to the impact of market fluctuations associated with commodity prices and interest rates. The Company has policies and procedures to assist in controlling these market risks and utilizes derivatives to manage a portion of its risk.

Commodity price risk

Fidelity utilizes natural gas and oil price swap and collar agreements to manage a portion of the market risk associated with fluctuations in the price of natural gas and oil on its forecasted sales of natural gas and oil production. For more information on commodity price risk, see Part II, Item 7A in the 2004 Annual Report, and Notes 11 and 14 of Notes to Consolidated Financial Statements.

Foreign currency risk

The Company's investment, through an indirect wholly owned subsidiary, in the Termoceara Generating Facility was sold as discussed in Note 12 of Notes to Consolidated Financial Statements and, as a result, the Company no longer has any material exposure to foreign currency exchange risk.

ITEM 4. CONTROLS AND PROCEDURES

The following information includes the evaluation of disclosure controls and procedures by the Company's chief executive officer and the chief financial officer, along with any significant changes in internal controls of the Company.

Evaluation of disclosure controls and procedures

The term "disclosure controls and procedures" is defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (Exchange Act). These rules refer to the controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports it files under the Exchange Act is recorded, processed, summarized and reported within required time periods. The Company's chief executive officer and chief financial officer have evaluated the effectiveness of the Company's disclosure controls and procedures and they have concluded that, as of the end of the period covered by this report, such controls and procedures were effective.

Changes in internal controls

The Company maintains a system of internal accounting controls that is designed to provide reasonable assurance that the Company's transactions are properly authorized, the Company's assets are safeguarded against unauthorized or improper use, and the Company's transactions are properly recorded and reported to permit preparation of the Company's financial statements in conformity with generally accepted accounting principles in the United States of America. There were no changes in the Company's internal control over financial reporting that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

Ladies and Gentlemen:

Centennial Energy Holdings, Inc., a Delaware corporation (the "Company"), agrees with you as follows:

1. RESTATEMENT AND AMENDMENT; AUTHORIZATION OF NOTES.

1.1. Restatement and Amendment of Existing Agreement. The Company and PICA entered into a Master Shelf Agreement dated as of December 27, 1999 (the "Original Agreement"), as amended by Letter Amendment No. 1 dated May 4, 2000, Letter Amendment No. 2 dated September 29, 2000, Letter Amendment No. 3 dated September 4, 2001, Letter Amendment No. 4 dated October 1, 2002 and Letter Amendment No. 5 dated December 15, 2004. (The Original Agreement, as amended, is referred to herein as the "Existing Agreement".) The Company, Prudential and each holder of Notes outstanding under the Existing Agreement desire to, among other things, amend certain provisions of the Existing Agreement including, without limitation, to increase the size of the Facility from $400,000,000 to $450,000,000 and extend the period during which Notes may be issued. Accordingly, the Company, Prudential and each holder of Notes outstanding under the Existing Agreement agree that the Existing Agreement is amended and restated in its entirety to read as provided in this Agreement.

1.2. Authorization of Issue of Notes. The Company will authorize the issue of its senior promissory notes (the "Notes") in the aggregate principal amount of $450,000,000 to be dated the date of issue thereof; to mature, in the case of each Note so issued, no more than 12 years after the date of original issuance thereof; to have an average life, in the case of each note so issued, of no more than 10 years after the date of original issuance thereof; to bear interest on the unpaid balance thereof from the date thereof at the rate per annum, and to have such other particular terms, as shall be set forth, in the case of each Note so issued, in the Confirmation of Acceptance with respect to such Note delivered pursuant to Section 2.6; and to be substantially in the form of Exhibit 1 attached hereto. The term "Notes" as used herein shall include each Note delivered pursuant to any provision of this Agreement and each Note delivered in substitution or exchange for any such Note pursuant to any such provision. Notes which have (i) the same final maturity, (ii) the same installment payment dates, (iii) the same installment payment amounts (as a percentage of the original principal amount of each Note), (iv) the same interest rate, (v) the same interest payment periods, and (vi) the same original date of issuance are herein called a "Series" of Notes. Certain capitalized terms used in this Agreement are defined in Schedule B; references to a "Schedule" or an "Exhibit" are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement.

2. SALE AND PURCHASE OF NOTES.

2.1. Facility; Limitation on Facility.

(a) Facility. Prudential is willing to consider, in its sole discretion and within limits which may be authorized for purchase by Prudential Affiliates from time to time, the purchase of $450,000,000 of the total amount of authorized Notes pursuant to this Agreement. The willingness of Prudential to consider such purchase of Notes is herein called the "Facility." At any time, subject to the additional limitations in Section 2.1(b), the aggregate principal amount of Notes stated in Section 1.2, minus the aggregate principal amount of Notes purchased and sold pursuant to this Agreement prior to such time, minus the aggregate principal amount of Accepted Notes which have not yet been purchased and sold hereunder prior to such time, plus the aggregate principal amount of Notes purchased and sold pursuant to this Agreement and thereafter retired prior to such time (to the extent that the Company shall have agreed with Prudential to reinstate the Facility with respect to such amount) is herein called the "Available Facility Amount" at such time.
NOTWITHSTANDING THE WILLINGNESS OF PRUDENTIAL TO CONSIDER PURCHASES OF NOTES, THIS AGREEMENT IS ENTERED INTO ON THE EXPRESS UNDERSTANDING THAT NEITHER PRUDENTIAL NOR ANY PRUDENTIAL AFFILIATE SHALL BE OBLIGATED TO MAKE OR ACCEPT OFFERS TO PURCHASE NOTES, OR TO QUOTE RATES, SPREADS OR OTHER TERMS WITH RESPECT TO SPECIFIC PURCHASES OF NOTES, AND THE FACILITY SHALL IN NO WAY BE CONSTRUED AS A COMMITMENT BY PRUDENTIAL OR ANY PRUDENTIAL AFFILIATE.

(b) Limitation on Facility. Notwithstanding anything in Section 2.1(a), the Company may not request the issuance of Notes, and neither Prudential nor any Prudential Affiliate shall be required to purchase Notes, pursuant to the Facility if, after the issuance of such Notes, the aggregate amount of Centennial Exposure would exceed $325,000,000.

2.2. Issuance Period.

Notes may be issued and sold pursuant to this Agreement until the earlier of (i) April 29, 2008 (or if any such anniversary is not a Business Day, the Business Day next preceding such anniversary) and (ii) the thirtieth day after Prudential shall have given to the Company, or the Company shall have given to Prudential, a notice stating that it elects to terminate the issuance and sale of Notes pursuant to this Agreement (or if such thirtieth day is not a Business Day, the Business Day next preceding such thirtieth day). The period during which Notes may be issued and sold pursuant to this Agreement is herein called the "Issuance Period".

2.3. Periodic Spread Information.

Provided no Default or Event of Default exists, not later than 9:30 A.M. (New York City local time) on a Business Day during the Issuance Period if there is an Available Facility Amount on such Business Day, the Company may request by telecopier or telephone, and Prudential will, to the extent reasonably practicable, provide to the Company on such Business Day (or, if such request is received after 9:30 A.M. (New York City local time) on such Business Day, on the following Business Day), information (by telecopier or telephone) with respect to various spreads at which Prudential Affiliates might be interested in purchasing Notes of different average lives; provided, however, that the Company may not make such requests more frequently than once in every five Business Days or such other period as shall be mutually agreed to by the Company and Prudential. The amount and content of information so provided shall be in the sole discretion of Prudential but it is the intent of Prudential to provide information which will be of use to the Company in determining whether to initiate procedures for use of the Facility. Information so provided shall not constitute an offer to purchase Notes, and neither Prudential nor any Prudential Affiliate shall be obligated to purchase Notes at the spreads specified. Information so provided shall be representative of potential interest only for the period commencing on the day such information is provided and ending on the earlier of the fifth Business Day after such day and the first day after such day on which further spread information is provided. Prudential may suspend or terminate providing information pursuant to this Section 2.3 if, in its sole discretion, it determines that there has been an adverse change in the credit quality of the Company after the Effective Date.

2.4. Request for Purchase.

The Company may from time to time during the Issuance Period make requests for purchases of Notes (each such request being a "Request for Purchase"). Each Request for Purchase shall be made to Prudential by telecopier and confirmed by nationwide overnight delivery service, shall be on the letterhead of the Company, and shall (i) specify the aggregate principal amount of Notes covered thereby, which shall not be less than $5,000,000 and not be greater than the Available Facility Amount (and shall be subject to the limitations of Section 2.1(b)) at the time such Request for Purchase is made if the request is made, (ii) specify the principal amounts, final maturities, installment payment dates and amounts and interest payment periods (quarterly or semi- annual in arrears) of the Notes covered thereby, (iii) specify the use of proceeds of such Notes, (iv) specify the proposed day for the closing of the purchase and sale of such Notes, which shall be a Business Day during the Issuance Period not less than 10 days and not more than 20 days after the making of such Request for Purchase, (v) specify the number of the account and the name and address of the depository institution to which the purchase prices of such Notes are to be transferred on the Closing Day for such purchase and sale, (vi) certify that the representations and warranties contained in Section 5 (as they may have been amended pursuant to this Section 2.4) are true on and as of the date of such Request for Purchase except to the extent of changes caused by the transactions herein contemplated and that there exists on the date of such Request for Purchase no Event of Default or Default, and (vii) be substantially in the form of Exhibit 2.4 attached hereto. Each Request for Purchase shall be in writing and shall be deemed made when received by Prudential. Any previous notification referenced in a Request for Purchase or any Request for Purchase that contains information that purports to amend the information contained in any Schedule or Exhibit hereto, shall not be effective to amend such information unless it is received by Prudential at least five Business Days prior to the Acceptance Day for Notes to which such Request for Purchase relates. If Prudential provides such interest rates quotes earlier than five Business Days after Prudential receives a Request for Purchase which contains information that purports to amend the information contained in any Schedule or Exhibit hereto and Prudential states in writing that it waives the requirement in this Section 2.4 that the information shall not be effective to amend unless it is received by Prudential at least five Business Days prior to the Acceptance Day, the information contained in such Schedule or Exhibit shall be deemed effective to amend such information at the time of the issuance of the quotes.

2.5. Rate Quotes.

Not later than six Business Days after the Company shall have given Prudential a Request for Purchase pursuant to
Section 2.4, Prudential may provide (by telephone promptly thereafter confirmed by telecopier, in each case no earlier than 9:30 A.M. and no later than 1:30 P.M. New York City local time) interest rate quotes for the several principal amounts, maturities, installment payment schedules, and interest payment periods of Notes specified in such Request for Purchase. Each quote shall represent the interest rate per annum payable on the outstanding principal balance of such Notes until such balance shall have become due and payable, at which a Prudential Affiliate would be willing to purchase such Notes at 100% of the principal amount thereof.

2.6. Acceptance.

Within 30 minutes after Prudential shall have provided any interest rate quotes pursuant to Section 2.5 or, in the event that due to conditions in the market place it shall not be feasible to hold such interest rate quotes open 30 minutes, such shorter period as Prudential may specify to the Company (such period being the "Acceptance Window"), the Company may, subject to Section 2.7, elect to accept such interest rate quotes as to not less than $5,000,000 aggregate principal amount of the Notes specified in the related Request for Purchase. Such election shall be made by an Authorized Officer of the Company notifying Prudential by telephone or telecopier within the Acceptance Window (but not earlier than 9:30 A.M. or later than 1:30 P.M., New York City local time) that the Company elects to accept such interest rate quotes, specifying the Notes (each such Note being an "Accepted Note") as to which such acceptance (an "Acceptance") relates. The day the Company notifies an Acceptance with respect to any Accepted Notes is herein called the "Acceptance Day" for such Accepted Notes. Any interest rate quotes as to which Prudential does not receive an Acceptance within the Acceptance Window shall expire, and no purchase or sale of Notes hereunder shall be made based on such expired interest rate quotes. Subject to Section 2.7 and the other terms and conditions hereof, the Company agrees to sell to a Prudential Affiliate, and Prudential agrees to cause the purchase by a Prudential Affiliate of, the Accepted Notes at 100% of the principal amount of such Notes. As soon as practicable following the Acceptance Day, the Company, Prudential and each Prudential Affiliate which is to purchase any such Accepted Notes will execute a confirmation of such Acceptance substantially in the form of Exhibit 2.6 attached hereto (a "Confirmation of Acceptance").

2.7. Market Disruption.

Notwithstanding the provisions of Section 2.6, if Prudential shall have provided interest rate quotes pursuant to
Section 2.5 and thereafter prior to the time an Acceptance with respect to such quotes shall have been notified to Prudential in accordance with Section 2.6 there shall occur a general suspension, material limitation, or significant disruption of trading in securities generally on the New York Stock Exchange or in the market for U.S. Treasury securities and other financial instruments, then such interest rate quotes shall expire, and no purchase or sale of Notes hereunder shall be made based on such expired interest rate quotes. If the Company thereafter notifies Prudential of the Acceptance of any such interest rate quotes, such Acceptance shall be ineffective for all purposes of this Agreement, and Prudential shall promptly notify the Company that the provisions of this Section 2.7 are applicable with respect to such Acceptance.

2.8. Fees.

(a) Facility Fee. The Company will pay to each Purchaser in immediately available funds a fee (the "Facility Fee") on each Closing Day on or after January 30, 2000, in an amount equal to 0.125% of the aggregate principal amount of Notes sold to such Purchaser on such Closing Day.

(b) Delayed Delivery Fee. If the closing of the purchase and sale of any Accepted Note is delayed for any reason (other than in the case where all conditions in Section 4 (other than Section 4.5 and Section 4.7) have been satisfied and a Purchaser fails to purchase its Accepted Notes) beyond the original Closing Day for such Accepted Note, the Company will pay to Prudential on the Cancellation Date or actual closing date of such purchase and sale (if such Cancellation Date or closing date occurs on a date later than the date specified in the Confirmation of Acceptance for such Accepted Note), a fee (the "Delayed Delivery Fee") calculated as follows:

(BEY - MMY) X DTS/360 X PA

where "BEY" means Bond Equivalent Yield, i.e., the bond equivalent yield per annum of such Accepted Note, "MMY" means Money Market Yield, i.e., the yield per annum on an alternative investment selected by Prudential on the date Prudential receives notice of the delay in the closing for such Accepted Notes having a maturity date or dates the same as, or closest to, the Rescheduled Closing Day or Rescheduled Closing Days (a new alternative investment being selected by Prudential each time such closing is delayed); "DTS" means Days to Settlement, i.e., the number of actual days elapsed from and including the originally scheduled Closing Day with respect to such Accepted Note (in the case of the first such payment with respect to such Accepted Note) or from and including the date of the next preceding payment (in the case of any subsequent delayed delivery fee payment with respect to such Accepted Note) to but excluding the date of such payment; and "PA" means Principal Amount, i.e., the principal amount of the Accepted Note for which such calculation is being made. In no case shall the Delayed Delivery Fee be less than zero. Nothing contained herein shall obligate any Purchaser to purchase any Accepted Note on any day other than the Closing Day for such Accepted Note, as the same may be rescheduled from time to time in compliance with Section 3.2.

(c) Cancellation Fee. If the Company at any time notifies Prudential in writing that the Company is canceling the closing of the purchase and sale of any Accepted Note, or if Prudential notifies the Company in writing under the circumstances set forth in the last sentence of Section 3.2 that the closing of the purchase and sale of such Accepted Note is to be canceled, or if the closing of the purchase and sale of such Accepted Note is not consummated on or prior to the last day of the Issuance Period (the date of any such notification, or the last day of the Issuance Period, as the case may be, being the "Cancellation Date"), the Company will pay Prudential in immediately available funds an amount (the "Cancellation Fee") calculated as follows:

PI X PA

where "PI" means Price Increase, i.e., the quotient (expressed in decimals) obtained by dividing (a) the excess of the ask price (as determined by Prudential) of the Hedge Treasury Note(s) on the Cancellation Date over the bid price (as determined by Prudential) of the Hedge Treasury Notes(s) on the Acceptance Day for such Accepted Note by (b) such bid price; and "PA" has the meaning specified in Section 2.8(b). The foregoing bid and ask prices shall be as reported by Telerate Systems, Inc. (or, if such data for any reason ceases to be available through Telerate Systems, Inc., any publicly available source of similar market data). Each price shall be based on a U.S. Treasury security having a par value of $100.00 and shall be rounded to the second decimal place. In no case shall the Cancellation Fee be less than zero.

(d) Structuring Fee. The Company paid PICA a fee of $75,000 at the time of the execution and delivery of the Original Agreement. The Company will pay to Prudential in immediately available funds a fee (the "Structuring Fee") on October 28, 2005 in an amount equal to $50,000 unless after the Effective Date and
(I) on or before October 28, 2005 the Company issues at least $50,000,000 of Notes or (II) on or before July 29, 2005 the Company issues at least $25,000,000 of Notes.

3. CLOSING.

3.1. Closings.

Not later than 11:30 A.M. (New York City local time) on the Closing Day for any Accepted Notes, the Company will deliver to each Purchaser listed in the Confirmation of Acceptance relating thereto at the offices of Prudential Capital Group, 2200 Ross Avenue, Suite 4200E, Dallas, Texas, 75201 the Accepted Notes to be purchased by such Purchaser in the form of one or more Notes in authorized denominations as such Purchaser may request for each Series of Accepted Notes to be purchased on the Closing Day, dated the Closing Day and registered in such Purchaser's name (or in the name of its nominee), against payment of the purchase price thereof by transfer of immediately available funds for credit to the Company's account specified in the Request for Purchase of such Notes.

3.2. Rescheduled Closings.

If the Company fails to tender to any Purchaser the Accepted Notes to be purchased by such Purchaser on the scheduled Closing Day for such Accepted Notes as provided in Section 3.1, or any of the conditions specified in Section 4 shall not have been fulfilled by the time required on such scheduled Closing Day, the Company shall, prior to 1:00 P.M., New York City local time, on such scheduled Closing Day notify such Purchaser in writing whether (i) such closing is to be rescheduled (such rescheduled date to be a Business Day during the Issuance Period not less than one Business Day and not more than 30 Business Days after such scheduled Closing Day (the "Rescheduled Closing Day") and certify to such Purchaser that the Company reasonably believes that it will be able to comply with the conditions set forth in Section 4 on such Rescheduled Closing Day and that the Company will pay the Delayed Delivery Fee in accordance with
Section 2.8(b) or (ii) such closing is to be canceled as provided in Section 2.8(c). In the event that the Company shall fail to give such notice referred to in the preceding sentence, such Purchaser may at its election, at any time after 1:00 P.M., New York City local time, on such scheduled Closing Day, notify the Company in writing that such closing is to be canceled as provided in Section 2.8(c).

4. CONDITIONS TO CLOSING.

The obligation of any Purchaser to purchase and pay for any Accepted Notes is subject to the fulfillment to such Purchaser's satisfaction, prior to or at the Closing Day for such Accepted Notes, of the following conditions:

4.1. Representations and Warranties.

The representations and warranties of the Company in this Agreement shall be correct when made and at such Closing Day.

4.2. Performance; No Default.

The Company shall have performed and complied with all agreements and conditions contained in this Agreement required to be performed or complied with by it prior to or at such Closing Day and after giving effect to the issue and sale of such Accepted Notes (and the application of the proceeds thereof as contemplated by the Request for Purchase for such Accepted Notes) no Default or Event of Default shall have occurred and be continuing. Neither the Company nor any Subsidiary shall have entered into any transaction from December 31, 2004 to the Effective Date, that would have been prohibited by Sections 10.1 through 10.12, hereof had such Sections applied since such date.

4.3. Compliance Certificates.

(a) Officer's Certificate. The Company shall have delivered to such Purchaser an Officer's Certificate, dated the date of such Closing Day, certifying that the conditions specified in Sections 4.1, 4.2 and 4.8 have been fulfilled.

Sandness, General Counsel of the Company, or Cynthia J. Norland, Associate General Counsel of the Company covering the matters set forth in Exhibits 4.4(a) and 4.4(b), respectively, and covering such other matters incident to the transactions contemplated hereby as such Purchaser or its counsel may reasonably request. The Company hereby directs each such counsel to deliver such opinion and agrees that the issuance and sale of any Accepted Notes will constitute a renewal of such direction. The Company has advised such counsel that each Purchaser receiving such an opinion will rely on such opinion, as of the date of such opinion.

4.5. Purchase Permitted By Applicable Law, etc.

On such Closing Day the purchase of Notes by such Purchaser shall (i) be permitted by the laws and regulations of each jurisdiction to which it is subject, without recourse to provisions (such as Section 1405(a)(8) of the New York Insurance Law) permitting limited investments by insurance companies without restriction as to the character of the particular investment, (ii) not violate any applicable law or regulation (including, without limitation, Regulation T, U or X of the Board of Governors of the Federal Reserve System) and (iii) not subject such Purchaser to any tax, penalty or liability under or pursuant to any applicable law or regulation, which law or regulation was not in effect on the date hereof. If requested, such Purchaser shall have received an Officer's Certificate certifying as to such matters of fact as it may reasonably specify to enable such Purchaser to determine whether such purchase is so permitted.

4.6. Payment of Facility Fee and Structuring Fee.

The Company shall have paid on or before such Closing Day the Facility Fee required by Section 2.8(a) for such Accepted Notes and the Structuring Fee, if required by Section 2.8(d).

The Company will give each holder of Notes of each Series written notice of each optional prepayment under this

Each such notice shall specify such date, the aggregate principal amount of the Notes of each Series to be prepaid on such date, the principal amount of each Note of such Series held by such holder to be prepaid (determined in accordance with Section 8.3), and the interest to be paid on the prepayment date with respect to such principal amount being prepaid, and shall be accompanied by a certificate of a Senior Financial Officer as to the estimated Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation.

In the case of each prepayment of Notes pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment, together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount, if any.

8.6. Make-Whole Amount.

The term "Make-Whole Amount" means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:

"Called Principal" means, with respect to any Note, the principal of such Note that is to be prepaid pursuant to
Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

"Designated Spread" shall mean 0% in the case of each Note of any Series unless the Confirmation of Acceptance with respect to the Notes of such Series specifies a different Designated Spread in which case it shall mean, with respect to each Note of such Series, the Designated Spread so specified.

"Discounted Value" means, with respect to the Called Principal of any Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.

"Reinvestment Yield" means, with respect to the Called Principal of any Note, the Designated Spread over the yield to maturity implied by (i) the yields reported, as of 10:00 A.M. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as "Page PX1" on Bloomberg Financial Markets PX1 ("Bloomberg") (or such other display as may replace Page PX1 on Bloomberg) for actively traded U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable, the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (519) (or any comparable successor publication) for actively traded U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. Such implied yield will be determined, if necessary, by (x) converting U.S. Treasury bill quotations to bond-equivalent yields in accordance with accepted financial practice and (y) interpolating linearly between (1) the actively traded U.S. Treasury security with the duration closest to and greater than the Remaining Average Life and (2) the actively traded U.S. Treasury security with the duration closest to and less than the Remaining Average Life.

"Remaining Average Life" means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by
(b) the number of years (calculated to the nearest one- twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

"Remaining Scheduled Payments" means, with respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 or 12.1.

"Settlement Date" means, with respect to the Called Principal of any Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

12. REMEDIES ON DEFAULT, ETC.

12.1. Acceleration.

(a) If an Event of Default with respect to the Company described in paragraph (g) or (h) of Section 11 (other than an Event of Default described in clause (i) of paragraph (g) or described in clause (vi) of paragraph (g) by virtue of the fact that such clause encompasses clause (i) of paragraph (g)) has occurred, all the Notes then outstanding shall automatically become immediately due and payable.

(b) If any other Event of Default has occurred and is continuing, the Required Holders of the Notes at the time outstanding may at any time at its or their option, by notice or notices to the Company, declare all the Notes then outstanding to be immediately due and payable.

(c) If any Event of Default described in paragraph (a) or (b) of Section 11 has occurred and is continuing, any holder or holders of Notes at the time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company, declare all the Notes held by it or them to be immediately due and payable.

Upon any Notes becoming due and payable under this
Section 12.1, whether automatically or by declaration, such Notes will forthwith mature and the entire unpaid principal amount of such Notes, plus (x) all accrued and unpaid interest thereon and
(y) the Make-Whole Amount determined in respect of such principal amount (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. The Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for) and that the provision for payment of a Make-Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances.

12.2. Other Remedies.

If any Default or Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise.

12.3. Rescission.

At any time after any Notes have been declared due and payable pursuant to clause (b) or (c) of Section 12.1, the Required Holders of the Notes, by written notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the Notes, all principal of and Make-Whole Amount, if any, on any Notes that are due and payable and are unpaid other than by reason of such declaration, and all interest on such overdue principal and Make- Whole Amount, if any, and (to the extent permitted by applicable law) any overdue interest in respect of the Notes, at the Default Rate, (b) all Events of Default and Defaults, other than non- payment of amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to
Section 17, and (c) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to the Notes. No rescission and annulment under this Section 12.3 will extend to or affect any subsequent Event of Default or Default or impair any right consequent thereon.

12.4. No Waivers or Election of Remedies, Expenses, etc.

No course of dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder's rights, powers or remedies. No right, power or remedy conferred by this Agreement or by any Note upon any holder thereof shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Company under Section 15, the Company will pay to the holder of each Note on demand such further amount as shall be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 12, including, without limitation, reasonable attorneys' fees, expenses and disbursements.

13. REGISTRATION; EXCHANGE; SUBSTITUTION OF NOTES.

13.1. Registration of Notes.

The Company shall keep at its principal executive office a register for the registration and registration of transfers of Notes. The name and address of each holder of one or more Notes, each transfer thereof and the name and address of each transferee of one or more Notes shall be registered in such register. Prior to due presentment for registration of transfer, the Person in whose name any Note shall be registered shall be deemed and treated as the owner and holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary. The Company shall give to any holder of a Note that is an Institutional Investor promptly upon request therefor, a complete and correct copy of the names and addresses of all registered holders of Notes.

13.2. Transfer and Exchange of Notes.

Upon surrender of any Note at the principal executive office of the Company for registration of transfer or exchange (and in the case of a surrender for registration of transfer, duly endorsed or accompanied by a written instrument of transfer duly executed by the registered holder of such Note or his attorney duly authorized in writing and accompanied by the address for notices of each transferee of such Note or part thereof), the Company shall execute and deliver, at the Company's expense (except as provided below), one or more new Notes (as requested by the holder thereof) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered Note. Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of Exhibit 1. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect of any such transfer of Notes. Notes shall not be transferred in denominations of less than $2,000,000, provided that if necessary to enable the registration of transfer by a holder of its entire holding of Notes, one Note may be in a denomination of less than $2,000,000. Any transferee, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed to have made the representation set forth in Section 6.2.

13.3. Replacement of Notes.

Upon receipt by the Company of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Note (which evidence shall be, in the case of an Institutional Investor, notice from such Institutional Investor of such ownership and such loss, theft, destruction or mutilation), and

(a) in the case of loss, theft or destruction, of indemnity reasonably satisfactory to it (provided that if the holder of such Note is a Prudential Affiliate, or a nominee of a Prudential Affiliate, or another holder of a Note with a minimum net worth of at least $50,000,000, a Prudential Affiliate's or such other holder's own unsecured agreement of indemnity shall be deemed to be satisfactory), or

(b) in the case of mutilation, upon surrender and cancellation thereof, the Company at its own expense shall execute and deliver, in lieu thereof, a new Note, dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon.

14. PAYMENTS ON NOTES.

14.1. Place of Payment.

Subject to Section 14.2, payments of principal, Make- Whole Amount, if any, and interest becoming due and payable on the Notes shall be made in New York, New York, at the principal office of The Bank of New York in such jurisdiction. The Company may at any time, by notice to each holder of a Note, change the place of payment of the Notes so long as such place of payment shall be either the principal office of the Company in such jurisdiction or the principal office of a bank or trust company in such jurisdiction.

14.2. Home Office Payment.

So long as any Purchaser shall be the holder of any Note, and notwithstanding anything contained in Section 14.1 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, Make-Whole Amount, if any, and interest by the method and at the address specified for such purpose below such Purchaser's name in Schedule A, or by such other method or at such other address as a holder of Notes shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment in full of any Note, such Purchaser shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by the Company pursuant to Section 14.1. Prior to any sale or other disposition of any Note held by a Purchaser, such Purchaser will, at its election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes pursuant to
Section 13.2. The Company will afford the benefits of this
Section 14.2 to any Institutional Investor that is the direct or indirect transferee of any Note purchased by any Purchaser under this Agreement and that has made the same agreement relating to such Note as the Purchasers have made in this Section 14.2.

15. EXPENSES, ETC.

15.1. Transaction Expenses.

Whether or not the transactions contemplated hereby are consummated, the Company will pay all costs and expenses (including reasonable attorneys' fees of a special counsel and, if reasonably required, local or other counsel) incurred by a Purchaser or each other holder of a Note in connection with such transactions and in connection with any amendments, waivers or consents under or in respect of this Agreement or the Notes (whether or not such amendment, waiver or consent becomes effective), including, without limitation: (a) the costs and expenses incurred in enforcing or defending (or determining whether or how to enforce or defend) any rights under this Agreement or the Notes or in responding to any subpoena or other legal process or informal investigative demand issued in connection with this Agreement or the Notes, or by reason of being a holder of any Note, and (b) the costs and expenses, including financial advisors' fees, incurred in connection with the insolvency or bankruptcy of the Company or any Subsidiary or in connection with any work-out or restructuring of the transactions contemplated hereby and by the Notes. The Company will pay, and will save any Purchaser and each other holder of a Note harmless from, all claims in respect of any fees, costs or expenses if any, of brokers and finders (other than those retained by such Purchaser). The Company's obligations to pay the fees of special counsel to the Purchasers in connection with the negotiation, execution and delivery of this Agreement as required by this Section 15.1 shall be deemed to have been fully satisfied.

15.2. Survival.

The obligations of the Company under this Section 15 will survive the payment or transfer of any Note, the enforcement, amendment or waiver of any provision of this Agreement or the Notes, and the termination of this Agreement.

16. SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT.

All representations and warranties contained herein shall survive the execution and delivery of this Agreement and the Notes, the purchase or transfer by any Purchaser of any Note or portion thereof or interest therein and the payment of any Note, and may be relied upon by any subsequent holder of a Note, regardless of any investigation made at any time by or on behalf of any Purchaser or any other holder of a Note. All statements contained in any certificate or other instrument delivered by or on behalf of the Company pursuant to this Agreement shall be deemed representations and warranties of the Company under this Agreement. Subject to the preceding sentence, this Agreement and the Notes embody the entire agreement and understanding between the Purchasers and the Company and supersede all prior agreements and understandings relating to the subject matter hereof.

17. AMENDMENT AND WAIVER.

17.1. Requirements.

This Agreement and the Notes may be amended, and the observance of any term hereof or of the Notes may be waived (either retroactively or prospectively), with (and only with) the written consent of the Company and the Required Holders, except that (a) with the written consent of the holders of all Notes of a particular Series, and if an Event of Default shall have occurred and be continuing, of the holders of all Notes of all Series, at the time outstanding (and not without such written consents), the Notes of such Series may be amended, or the provisions thereof waived, to change the maturity thereof, to change or affect the principal thereof, or to change or affect the rate or time of payment of interest on or any Make-Whole Amount payable with respect to the Notes of such Series, (b) without the written consent of the holder or holders of all Notes at the time outstanding, no amendment to, or waiver of, the provisions of this Agreement shall change or affect the provisions of (i) Sections 8, 11(a), 11(b), 12, 17, or 20 insofar as such provisions relate to proportions of the principal amount of the Notes of any Series, or the rights of any individual holder of Notes, required with respect to any declaration of Notes to be due and payable or with respect to any consent, amendment, waiver or declaration, or (ii) amend the definition of "Change of Control" or any constituent definitions thereof,
(c) with the written consent of Prudential (and not without the written consent of Prudential) the provisions of Section 2 may be amended or waived (except insofar as any such amendment or waiver would affect any rights or obligations with respect to the purchase and sale of Notes which shall have become Accepted Notes prior to such amendment or waiver), (d) with the written consent of all of the Purchasers which shall have become obligated to purchase Accepted Notes of any Series (and not without the written consent of all such Purchasers), any of the provisions of Sections 2, 3 and 4 may be amended or waived insofar as such amendment or waiver would affect only rights or obligations with respect to the purchase and sale of the Accepted Notes of such Series or the terms and provisions of such Accepted Notes, and
(e) with the written consent of Prudential and Prudential Affiliates only the provisions of Section 10.11 may be amended or waived.

17.2. Solicitation of Holders of Notes.

(a) Solicitation. The Company will provide each holder of the Notes (irrespective of the amount of Notes then owned by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such holder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof or of the Notes. The Company will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 17 to each holder of outstanding Notes promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite holders of Notes.

(b) Payment. The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security, to any holder of Notes as consideration for or as an inducement to the entering into by any holder of Notes or any waiver or amendment of any of the terms and provisions hereof unless such remuneration is concurrently paid, or security is concurrently granted, on the same terms, ratably to each holder of Notes then outstanding even if such holder did not consent to such waiver or amendment.

17.3. Binding Effect, etc.

Any amendment or waiver consented to as provided in this Section 17 applies equally to all holders of Notes and is binding upon them and upon each future holder of any Note and upon the Company without regard to whether such Note has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Company and the holder of any Note nor any delay in exercising any rights hereunder or under any Note shall operate as a waiver of any rights of any holder of such Note. As used herein, the term "this Agreement" and references thereto shall mean this Agreement as it may from time to time be amended or supplemented.

17.4. Notes held by Company, etc.

Solely for the purpose of determining whether the holders of the requisite percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under this Agreement or the Notes, or have directed the taking of any action provided herein or in the Notes to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by the Company or any of its Affiliates shall be deemed not to be outstanding.

(ii) if to any other holder of any Note, to such holder at such address as such other holder shall have specified to the Company in writing, or

(iii) if to the Company, to the Company at its address set forth at the beginning hereof to the attention of Chief Financial Officer, or at such other address as the Company shall have specified to the holder of each Note in writing.

Notices under this Section 18 will be deemed given only when actually received.

19. REPRODUCTION OF DOCUMENTS.

This Agreement and all documents relating thereto, including, without limitation, (a) consents, waivers and modifications that may hereafter be executed, (b) documents received by a Purchaser on any Closing Day (except the Notes themselves), and (c) financial statements, certificates and other information previously or hereafter furnished to any Purchaser, may be reproduced by such Purchaser by any photographic, photostatic, microfilm, microcard, miniature photographic or other similar process and such Purchaser may destroy any original document so reproduced. The Company agrees and stipulates that, to the extent permitted by applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by a Purchaser in the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section 19 shall not prohibit the Company or any other holder of Notes from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction.

20. CONFIDENTIAL INFORMATION.

For the purposes of this Section 20, "Confidential Information" means (1) information delivered to Prudential or PICA prior to December 27, 1999 that was clearly marked or labeled or otherwise adequately identified as being confidential information when delivered, to the extent that it contains information that is proprietary in nature, and (2) information delivered on and after December 27, 1999 to Prudential or PICA, or any holder of Notes by or on behalf of the Company or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received by Prudential or PICA, or any holder of Notes as being confidential information of the Company or such Subsidiary, provided that such term does not include information that (a) was publicly known or otherwise known to Prudential or PICA, or any holder of Notes prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by Prudential or PICA, or any holder of Notes, or any person acting on its behalf, (c) otherwise becomes known to Prudential or PICA, or any holder of Notes other than through disclosure by the Company or any Subsidiary or (d) constitutes financial statements delivered to Prudential or PICA, or any holder of Notes under Section 7.1 that are otherwise publicly available. Prudential, PICA and any holder of Notes will maintain the confidentiality of such Confidential Information in accordance with procedures adopted by Prudential or PICA, or such holder of Notes, respectively, in good faith to protect confidential information of third parties delivered to Prudential or PICA, or such holder of Notes, provided that Prudential or PICA, or any holder of Notes may deliver or disclose Confidential Information to (i) its directors, officers, employees, agents, attorneys and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by its Notes), (ii) its financial advisors and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with the terms of this Section 20, (iii) any other holder of any Note,
(iv) any Institutional Investor to which it sells or offer to sell such Note or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 20), (v) any Person from which it offers to purchase any security of the Company (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 20), (vi) any federal or state regulatory authority having jurisdiction over it, (vii) the National Association of Insurance Commissioners or any similar organization, or any nationally recognized rating agency that requires access to information about its investment portfolio or
(viii) any other Person to which such delivery or disclosure may be necessary or appropriate (w) to effect compliance with any law, rule, regulation or order applicable to it, (x) in response to any subpoena or other legal process, (y) in connection with any litigation to which it is a party or (z) if an Event of Default has occurred and is continuing, to the extent it may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under its Notes and this Agreement. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 20 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Note of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying the provisions of this Section 20.

21. SUBSTITUTION OF PURCHASER.

Each Purchaser shall have the right to substitute any one of its Affiliates as the purchaser of the Notes that such Purchaser has agreed to purchase hereunder, by written notice to the Company, which notice shall be signed by both such Purchaser and such Affiliate, shall contain such Affiliate's agreement to be bound by this Agreement and shall contain a confirmation by such Affiliate of the accuracy with respect to it of the representations set forth in Section 6. Upon receipt of such notice, wherever the word "Purchaser" (or a pronoun referring to a Purchaser) is used in this Agreement (other than in this
Section 21), such word shall be deemed to refer to such Affiliate in lieu of such Purchaser. In the event that such Affiliate is so substituted as a purchaser hereunder and such Affiliate thereafter transfers to such Purchaser all of the Notes then held by such Affiliate, upon receipt by the Company of notice of such transfer, wherever the word "Purchaser" (or a pronoun referring to a Purchaser) is used in this Agreement (other than in this
Section 21), such word shall no longer be deemed to refer to such Affiliate, but shall refer to such Purchaser, and such Purchaser shall have all the rights of an original holder of the Notes under this Agreement.

22. MISCELLANEOUS.

22.1. Successors and Assigns.

All covenants and other agreements contained in this Agreement by or on behalf of either of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not.

22.2. Payments Due on Non-Business Days.

Anything in this Agreement or the Notes to the contrary notwithstanding, any payment of principal of or Make-Whole Amount or interest on any Note that is due on a date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day.

22.3. Severability.

Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.

22.4. Construction.

Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person.

22.5. Counterparts.

This Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of two copies hereof, each signed by either, but together signed by both, of the parties hereto.

22.6. Governing Law.

This Agreement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the law of the State of New York excluding, to the extent permitted by the law of such State, choice-of-law principles of the law of such State that would require the application of the laws of a jurisdiction other than such State.

Each Lender agrees, severally but not jointly, on the terms and subject to the conditions hereinafter set forth, to make Advances to the Borrower from time to time during the period from the date hereof to and including the Revolving Period Termination Date in an aggregate amount not to exceed at any time outstanding that Lender's Facility Amount. Each Borrowing shall be in an amount equal to an integral multiple of $500,000 and not less than $1,000,000 (or such greater amount as may be required pursuant to
Section 2.3(b) if any part of such Borrowing will constitute a LIBO Rate Funding). Through the Revolving Period Termination Date, the facility established hereby shall be a revolving facility; within the limits of the Aggregate Facility Amount, the Borrower may borrow, prepay pursuant to Section 2.7 and reborrow under this Section 2.1. The Advances made by each Lender shall be evidenced by a Note, payable to the order of that Lender in the face principal amount of that Lender's Facility Amount. Notwithstanding any other provision of this Agreement to the contrary, no Borrowing shall be effected on any Principal Payment Date.

Section 2.2 Procedure for Borrowings.

Each Borrowing shall occur on prior written request from the Borrower to the Agent or telephonic request from any person purporting to be authorized to request Borrowings on behalf of the Borrower, which request shall specify the date of the requested Borrowing and the amount thereof. Except as set forth in Section 2.3(b), each such request by the Borrower shall be made not less than one Business Day before the date of the requested Borrowing. Promptly upon receipt of such request, the Agent shall advise each Lender of the proposed Borrowing. At or before 2:00 p.m. on the date of the requested Borrowing, each Lender shall provide the Agent at the principal office of the Agent in Minneapolis, Minnesota with immediately available funds covering such Lender's Percentage of such Borrowing. The Agent shall disburse the amount of the requested Borrowing by crediting the same to the Borrower's demand deposit account maintained with the Agent or in such other manner as the Agent and the Borrower may from time to time agree; provided, however, that the Agent shall have no obligation to disburse the requested Borrowing if any condition set forth in Article III has not been satisfied on the day of the requested Borrowing or if any Lender has failed to fund its Percentage of the requested Borrowing. The Borrower shall promptly confirm each telephonic request for a Borrowing by executing and delivering an appropriate confirmation certificate to the Agent. The Borrower shall be obligated to repay all Advances notwithstanding the failure of the Agent to receive such confirmation and notwithstanding the fact that the person requesting same was not in fact authorized to do so. Any request for a Borrowing shall be deemed to be a representation that the statements set forth in Section 3.2 are correct.

Section 2.3 Interest on Notes.

(a) Floating Rate Fundings. Unless the Borrower elects a LIBO Rate pursuant to this Section, the principal balance of the Notes shall bear interest at the Floating Rate.

(b) LIBO Rate Fundings. So long as no Default or Event of Default exists, the Borrower may request that a portion of any requested Borrowing constitute a LIBO Rate Funding, or may convert all or any part of any outstanding Floating Rate Funding into a LIBO Rate Funding, or may request that a LIBO Rate Funding be converted at the end of the applicable Interest Period to another LIBO Rate Funding, by giving notice to the Agent of such request or conversion not later than 10:30 a.m. on a Business Day which is at least three Business Days prior to the date of the requested Borrowing or conversion. Each such notice shall be effective upon receipt by the Agent, shall be in writing or by telephone or telecopy transmission, shall specify the date and amount of such Borrowing or conversion, and the Interest Period therefor. The Interest Period applicable to each LIBO Rate Funding shall begin on a Business Day, and the amount of each LIBO Rate Funding shall be an integral multiple of $1,000,000 and not less than $5,000,000. Subject to the terms and conditions hereof, the principal amount specified by the Borrower in the applicable request for a LIBO Rate Funding shall bear interest from and including the first day of the Interest Period specified therein to but not including the last day of such Interest Period, at the LIBO Rate applicable thereto, determined as set forth herein, (subject to fluctuations in the applicable Margin). Unless the Borrower requests a new LIBO Rate Funding in accordance with the procedures set forth above, or prepays the principal of an outstanding LIBO Rate Funding at the expiration of an Interest Period, the Lenders shall automatically and without request of the Borrower convert each LIBO Rate Funding to a Floating Rate Funding on the last day of the relevant Interest Period.

(c) Setting of LIBO Rates. The applicable LIBO Rate for each Interest Period shall be determined by the Agent between the opening of business and 12:00 noon on the second Business Day prior to the beginning of such Interest Period, whereupon notice thereof (which may be by telephone) shall be given by the Agent to the Borrower and each Lender. Each such determination of the applicable LIBO Rate shall be conclusive and binding upon the parties hereto, in the absence of demonstrable error. The Agent, upon written request of the Borrower, shall deliver to the Borrower a statement showing the computations used by the Agent in determining the applicable LIBO Rate hereunder.

(d) Limitations on LIBO Rate Fundings. In no event shall more than 6 LIBO Rate Fundings be outstanding at any one time. In no event may the Borrower request a LIBO Rate Funding if, after giving effect to such LIBO Rate Funding, the Borrower would be required to prepay a LIBO Rate Funding in order to make any regularly scheduled principal payment.

Section 2.4 Principal and Interest Payment Dates.

(a) Interest. Interest accruing on Floating Rate Fundings shall be due and payable on the last day of each calendar quarter. Interest on any LIBO Rate Funding shall be due and payable on the last day of the applicable Interest Period or, if such Interest Period is in excess of three months, on the last day of each three-month period during such Interest Period and on the last day of such Interest Period.

(b) Principal. The Borrower shall pay the principal balance of all Borrowings then outstanding in full on each Principal Payment Date.

Section 2.5 Level Status, Margins and Fee Rates.

(a) The Borrower's Level Status shall be determined on the basis of the Applicable Ratings established by the Rating Agencies, in accordance with the following table:

Level I Level II Level III Level IV Level V

        A or      A- or     BBB+ or    BBB or   Less

                  but less  but less   but less
                  than A    than A-    than
                                       BBB+
        A2 or     A3 or     Baa1 or    Baa2 or  Less
Moody's better    better,   better,    better,  than
                  but less  but less   but less Baa2
                  than A2   than A3    than
                                       Baa1
Fitch   A or      A- or     BBB+ or    BBB or   Less
        better    better,   better,    better,  than BBB
                  but less  but less   but less
                  than A    than A-    than
                                       BBB+

If the Applicable Ratings established by the Rating Agencies differ such that they do not fall within a single column in the table set forth above, the Borrower's Level Status shall be determined as follows:

(i) If the Applicable Ratings applied by any two of the Rating Agencies are in the same column, the Borrower's Level Status shall be determined by that column.

(ii) If the Applicable Ratings are each in separate columns, the highest and lowest columns shall be excluded, and the Borrower's Level Status shall be determined by the remaining Applicable Rating.

(b) In making the determinations under paragraph (a):

(i) If any of the Rating Agencies changes the meaning or designation for its Applicable Ratings referenced in paragraph (a), the criteria for Level Status in the table in paragraph (a) shall be adjusted in such manner as the Required Lenders may reasonably determine to correspond with the applicable rating designations used by the applicable Rating Agency in effect on the date hereof.

(ii) If one of the Rating Agencies ceases to rate the Borrower's long-term unsecured debt such that only two of the Rating Agencies are providing such Applicable Ratings, the Borrower's Level Status shall be determined as follows:

(A) If the Applicable Ratings provided by both of the remaining Rating Agencies are in the same column, the Borrower's Level Status shall be determined by that column.

(B) If the Applicable Ratings provided by the remaining Rating Agencies are in adjacent columns, the Borrower's Level Status shall be based on the leftmost of the columns.

(C) If the Applicable Ratings provided by the remaining Rating Agencies are separated by one or more columns, the Borrower's Level Status shall be based on the column to the immediate right of the leftmost applicable column.

Notwithstanding the foregoing, if the Applicable Rating established by either of the remaining Rating Agencies is in the rightmost column above, the Borrower shall be deemed to be at Level Status V.

(iii)If any two of the Rating Agencies ceases to establish its Applicable Rating, the Borrower shall be deemed to be at Level Status V.

(c) The Floating Rate Margin, LIBO Rate Margin, Facility Fee Rate and Utilization Fee Rate at any time shall be determined from time to time on the basis of the Borrower's Level Status, in accordance with the following table:

                   Level I   Level II   Level III Level IV   Level V
Floating Rate
Margin             0%        0%         0%        0%         0%
LIBO Rate Margin
                   0.295%    0.400%     0.500%    0.600%     0.750%
Facility Fee Rate
                   0.080%    0.100%     0.125%    0.150%     0.200%
Utilization Fee

Rate 0.100% 0.100% 0.125% 0.125% 0.200%

(d) Upon the occurrence of any Default or Event of Default, and so long as such Default or Event of Default continues without written waiver thereof by the Lenders, a default increment equal to 200 basis points (2.00%) shall be added to the Floating Rate Margin and LIBO Rate Margin. Inclusion of such default increment shall not be deemed a waiver or excuse of any such Default or Event of Default.

Section 2.6 Fees.

(a) Facility Fee. The Borrower shall pay to the Agent, for the ratable benefit of the Lenders, a facility fee determined at an annual rate equal to the then-applicable Facility Fee Rate applied to the average Aggregate Facility Amount outstanding during such calendar quarter (or during such shorter period ending on the Revolving Period Termination Date). The facility fee shall be due and payable quarterly in arrears on the last day of each calendar quarter, and on the Maturity Date. The facility fee shall accrue at all times, including at any time during which any condition in Article III has not been satisfied.

(b) Utilization Fee. The Borrower shall pay to the Agent, for the ratable benefit of the Lenders, a utilization fee determined at an annual rate equal to the then- applicable Utilization Fee Rate applied to the actual daily aggregate principal balance of the Notes on each day that such aggregate principal balance exceeds 50% of the Aggregate Facility Amount in effect on such day. The utilization fee shall be due and payable quarterly in arrears on the last day of each calendar quarter, and on the Maturity Date. The utilization fee shall accrue at all times, including at any time during which any condition in Article III has not been satisfied.

(a) Making of Payments. All payments of principal of and interest due under the Notes shall be made to the Agent at its principal office in Minneapolis, Minnesota, not later than 12:00 noon on the date due, in immediately available funds, and funds received after that hour shall be deemed to have been received by the Agent on the next following Business Day.

(b) Assumed Payments. Unless the Agent has been notified by a Lender or the Borrower prior to the date on which such Lender or the Borrower is scheduled to make payment to the Agent of (in the case of a Lender) the proceeds of an Advance to be made by it hereunder or (in the case of the Borrower) a payment to the Agent for the account of one or more of the Lenders hereunder (such payment by a Lender or the Borrower (as the case may be) being herein called a "Required Payment"), which notice shall be effective upon receipt, that it does not intend to make the Required Payment to the Agent, the Agent may assume that the Required Payment has been made and may (but shall not be required to), in reliance upon such assumption, make the amount thereof available to the intended recipient on such date and, if such Lender or the Borrower (as the case may be) has not in fact made the Required Payment to the Agent, the recipient of such payment shall, on demand, repay to the Agent the amount so made available together with interest thereon for each day during the period commencing on the date such amount was so made available by the Agent until the date the Agent recovers such amount at a rate (i) equal to the Federal Funds Rate for such day, in the case of a Required Payment owing by a Lender, or (ii) equal to the applicable rate of interest as provided in this Agreement, in the case of a Required Payment owing by the Borrower.

(c) Setoff. The Borrower agrees that each Lender shall have all rights of setoff and bankers' lien provided by applicable law, and in addition thereto, the Borrower agrees that if at any time any amount is due and owing by the Borrower under this Agreement to any Lender at a time when an Event of Default has occurred and is continuing hereunder, any Lender may apply any and all balances, credits, and deposits, accounts or moneys of the Borrower then or thereafter in the possession of that Lender (excluding, however, any trust or escrow accounts held by the Borrower for the benefit of any third party) to the payment thereof.

(d) Due Date Extension. If any payment of principal of or interest on any Floating Rate Funding or any fees payable hereunder falls due on a day which is not a Business Day, then such due date shall be extended to the next following Business Day, and (in the case of principal) additional interest shall accrue and be payable for the period of such extension.

(e) Application of Payments. Except as otherwise provided herein, so long as no Default or Event of Default has occurred and is continuing hereunder, each payment received from the Borrower shall be applied to such obligation as the Borrower shall specify by notice received by the Agent on or before the date of such payment, or in the absence of such notice, as the Required Lenders shall determine in their discretion. Except as otherwise provided herein, after the occurrence of a Default or Event of Default, the Lenders shall have the right to apply all payments received by the Lender from the Borrower as the Required Lenders may determine in their discretion. The Borrower agrees that the amount shown on the books and records of the Agent and the Lenders as being the principal balance of and interest on the Notes shall be conclusive absent demonstrable error.

Section 2.10 Increased Costs; Capital Adequacy; Funding Exceptions.

(a) Increased Costs on LIBO Rate Fundings. If Regulation D of the Board of Governors of the Federal Reserve System or after the date of this Agreement the adoption of any applicable law, rule or regulation, or any change in any existing law, 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 Lender with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency, shall:

(i) subject that Lender to or cause the withdrawal or termination of any exemption previously granted to that Lender with respect to, any tax, duty or other charge with respect to its LIBO Rate Fundings or its obligation to make LIBO Rate Fundings, or shall change the basis of taxation of payments to that Lender of the principal of or interest under this Agreement in respect of its LIBO Rate Fundings or its obligation to make LIBO Rate Fundings (except for changes in the rate of tax on the overall net income of that Lender imposed by the jurisdictions in which that Lender's principal executive office is located); or

(ii) impose, modify or deem applicable any reserve (including, without limitation, any reserve imposed by the Board of Governors of the Federal Reserve System, but excluding any reserve included in the determination of interest rates pursuant to
Section 2.3), special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, that Lender; or

(iii)impose on that Lender any other condition affecting its making, maintaining or funding of its LIBO Rate Fundings or its obligation to make LIBO Rate Fundings;

and the result of any of the foregoing is to increase the cost to that Lender of making or maintaining any LIBO Rate Funding, or to reduce the amount of any sum received or receivable by that Lender under this Agreement or under its Notes with respect to a LIBO Rate Funding, then that Lender will notify the Borrower of such increased cost and within fifteen (15) days after demand by that Lender (which demand shall be accompanied by a statement setting forth the basis of such demand and representing that that Lender has made similar demand on one or more other commercial borrowers with revolving or term loans in excess of $1,000,000) the Borrower shall pay to that Lender such additional amount or amounts as will compensate that Lender for such increased cost or such reduction; provided, however, that no such increased cost or such reduction shall be payable by the Borrower for any period longer than ninety (90) days prior to the date on which notice thereof is delivered to the Borrower. Each Lender will promptly notify the Borrower of any event of which it has knowledge, occurring after the date hereof, which will entitle that Lender to compensation pursuant to this Section 2.10. If the Borrower receives notice from any Lender of any event which will entitle that Lender to compensation pursuant to this Section 2.10, the Borrower may prepay any then outstanding LIBO Rate Fundings or notify that Lender that any pending request for a LIBO Rate Funding shall be deemed to be a request for a Floating Rate Funding, in each case subject to the provisions of
Section 2.11.

(b) Capital Adequacy. If any Lender determines at any time that its Return has been reduced as a result of any Capital Adequacy Rule Change, that Lender may require the Borrower to pay it the amount necessary to restore that Lender's Return to what it would have been had there been no Capital Adequacy Rule Change. For purposes of this 2.10, the following definitions shall apply:

(i) "Return", for any calendar quarter or shorter period, means the percentage determined by dividing (A) the sum of interest and ongoing fees earned by a Lender under this Agreement during such period by (B) the average capital that Lender is required to maintain during such period as a result of its being a party to this Agreement, as determined by that Lender based upon its total capital requirements and a reasonable attribution formula that takes account of the Capital Adequacy Rules then in effect. Return may be calculated for each calendar quarter and for the shorter period between the end of a calendar quarter and the date of termination in whole of this Agreement.

(ii) "Capital Adequacy Rule" means any law, rule, regulation or guideline regarding capital adequacy that applies to any Lender, or the interpretation thereof by any governmental or regulatory authority. Capital Adequacy Rules include rules requiring financial institutions to maintain total capital in amounts based upon percentages of outstanding loans, binding loan commitments and letters of credit.

(iii)"Capital Adequacy Rule Change" means any change in any Capital Adequacy Rule occurring after the date of this Agreement, but does not include any changes in applicable requirements that at the date hereof are scheduled to take place under the existing Capital Adequacy Rules or any increases in the capital that any Lender is required to maintain to the extent that the increases are required due to a regulatory authority's assessment of that Lender's financial condition.

(iv) "Lender" includes (but is not limited to) the Agent, the Lenders, as defined elsewhere in this Agreement, and any assignee of any interest of any Lender hereunder and any participant in the loans made hereunder.

The initial notice sent by a Lender shall be sent as promptly as practicable after that Lender learns that its Return has been reduced, shall include a demand for payment of the amount necessary to restore that Lender's Return for the quarter in which the notice is sent, shall state in reasonable detail the cause for the reduction in that Lender's Return and that Lender's calculation of the amount of such reduction, and shall include that Lender's representation that it has made similar demand on one or more other commercial borrowers with revolving or term loans in excess of $1,000,000. Thereafter, that Lender may send a new notice during each calendar quarter setting forth the calculation of the reduced Return for that quarter and including a demand for payment of the amount necessary to restore that Lender's Return for that quarter. A Lender's calculation in any such notice shall be conclusive and binding absent demonstrable error.

(c) Basis for Determining Interest Rate Inadequate or Unfair. If with respect to any Interest Period:

(i) any Lender determines that deposits in U.S. dollars (in the applicable amounts) are not being offered in the London interbank eurodollar market for such Interest Period; or

(ii) any Lender otherwise determines that by reason of circumstances affecting the London interbank eurodollar market adequate and reasonable means do not exist for ascertaining the applicable LIBO Rate; or

(iii)any Lender determines that the LIBO Rate as determined by the Agent will not adequately and fairly reflect the cost to that Lender of maintaining or funding a LIBO Rate Funding for such Interest Period, or that the making or funding of LIBO Rate Fundings has become impracticable as a result of an event occurring after the date of this Agreement which in the opinion of that Lender materially affects such LIBO Rate Fundings;

then that Lender shall promptly notify the Borrower and (A) upon the occurrence of any event described in the foregoing clause (i) the Borrower shall enter into good faith negotiations with that Lender in order to determine an alternate method to determine the LIBO Rate for that Lender, and during the pendency of such negotiations with that Lender, the Lenders shall be under no obligation to make any new LIBO Rate Fundings, and (B) upon the occurrence of any event described in the foregoing clauses (ii) or (iii), for so long as such circumstances shall continue, the Lenders shall be under no obligation to make any new LIBO Rate Fundings.

(d) Illegality. If any change in (including the adoption of any new) applicable laws or regulations, or any change in the interpretation of applicable laws or regulations by any governmental authority, central bank, comparable agency or any other regulatory body charged with the interpretation, implementation or administration thereof, or compliance by any Lender with any request or directive (whether or not having the force of law) of any such authority, central bank, comparable agency or other regulatory body, should make it or, in the good faith judgment of that Lender, shall raise a substantial question as to whether it is unlawful for that Lender to make, maintain or fund LIBO Rate Fundings, then (i) that Lender shall promptly notify the Borrower and the Agent, (ii) the obligation of the Lenders to make, maintain or convert into LIBO Rate Fundings shall, upon the effectiveness of such event, be suspended for the duration of such unlawfulness, and (iii) for the duration of such unlawfulness, any notice by the Borrower requesting the Lenders to make or convert into LIBO Rate Fundings shall be construed as a request to make or to continue making Floating Rate Fundings.

Section 2.11 Funding Losses.

Upon demand by any Lender (which demand shall be accompanied by a statement setting forth the basis for the calculations of the amount being claimed), the Borrower shall indemnify that Lender against any loss or expense which that Lender may have sustained or incurred (including, without limitation, any net loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by that Lender to fund or maintain LIBO Rate Fundings) or which that Lender may be deemed to have sustained or incurred, as reasonably determined by that Lender, (i) as a consequence of any failure by the Borrower to make any payment when due of any amount due hereunder in connection with any LIBO Rate Fundings, (ii) due to any failure of the Borrower to borrow or convert any LIBO Rate Fundings on a date specified therefor in a notice thereof or (iii) due to any payment or prepayment of any LIBO Rate Funding on a date other than the last day of the applicable Interest Period for such LIBO Rate Funding. For this purpose, all notices under Section 2.3(b) shall be deemed to be irrevocable.

Section 2.12 Discretion of Lenders as to Manner of Funding.

Notwithstanding any provision of this Agreement to the contrary, each Lender shall be entitled to fund and maintain all or any part of its LIBO Rate Fundings in any manner it deems fit, it being understood, however, that for the purposes of this Agreement (specifically including, without limitation, Section 2.11 hereof) all determinations hereunder shall be made as if that Lender had actually funded and maintained each LIBO Rate Funding during each Interest Period for such LIBO Rate Funding through the purchase of deposits having a maturity corresponding to such Interest Period and bearing an interest rate equal to the appropriate LIBO Rate for such Interest Period.

Section 2.13 Conclusiveness of Statements; Survival of Provisions.

Determinations and statements of any Lender pursuant to Sections 2.10 and 2.11 shall be conclusive absent demonstrable error. Without limiting the generality of the foregoing, the Borrower shall have no right to review any records of any Lender or its other customers to determine the accuracy of any statement by that Lender under Section 2.10(a) or 2.10(b) regarding that Lender's demands upon other customers of that Lender. Each Lender may use reasonable averaging and attribution methods in determining compensation pursuant to such Sections 2.10 and 2.11 and the provisions of Sections 2.10 and 2.11 shall survive termination of this Agreement.

Section 2.14 Computation of Interest and Fees.

All interest determined at the Floating Rate will be calculated based on the actual days elapsed in a year of 365 or 366 days, as the case may be. All interest determined at the LIBO Rate and all fees hereunder shall be computed on the basis of actual number of days elapsed in a year of 360 days.

Section 2.15 Purpose of Borrowings.

The proceeds of the initial Borrowing hereunder shall be used to pay in full all obligations of the Borrower outstanding under the Existing Credit Facility, if any. The proceeds of each other Borrowing (including the initial Borrowing, if no obligations described in the preceding sentence are outstanding on the date thereof) shall be used solely (i) to pay the Borrower's obligations under (A) its commercial paper program, (B) other short-term credit facilities, and (C) maturing long-term obligations, and (ii) for the general corporate purposes of the Borrower in the ordinary course of business.

Section 2.16 Increase of Aggregate Facility Amount.

(a) So long as no Default or Event of Default has occurred and is continuing, the Borrower may, upon at least 25 days' written notice to the Agent, propose to increase the Aggregate Facility Amount by a multiple of $5,000,000 that is not less than $15,000,000 and not greater than $25,000,000 (the amount of any such increase, the "Additional Facility Amount"). In no event shall any such increase cause the Aggregate Facility Amount to exceed the Maximum Aggregate Facility Amount. The Agent will promptly provide a copy of any such notice to each Lender. Each Lender may, not more than 20 days following such notice, elect by written notice to the Borrower and the Agent to increase its Facility Amount by a principal amount equal to its Percentage of the Additional Facility Amount. No Lender (or any successor thereto) shall have any obligation to increase its Facility Amount or its other obligations under this Agreement and the other Loan Documents, and any decision by a Lender to increase its Facility Amount shall be made in its sole discretion independently from any other Lender.

(b) If any Lender elects not to increase its Facility Amount pursuant to paragraph (a), the Borrower may designate another Eligible Lender (which may be, but need not be, one or more of the existing Lenders) that will, in the case of any such Person that is an existing Lender, increase its Facility Amount and in the case of any other such Person (an "Incremental Lender"), become a party to this Agreement; provided, however, that any Incremental Lender must in all respects be acceptable to the Agent, which acceptance will not be unreasonably withheld. The sum of the increases in the Facility Amounts of the existing Lenders pursuant to this paragraph (b) plus the Facility Amounts of the Incremental Lenders shall not in the aggregate exceed the unsubscribed amount of the Maximum Aggregate Facility Amount.

(c) An increase in the Aggregate Facility Amount pursuant to this Section 2.16 shall become effective upon the receipt by the Agent of an agreement in form and substance satisfactory to the Agent signed by the Borrower, by each Incremental Lender and by each other Lender whose Aggregate Facility Amount is to be increased, setting forth the new Facility Amounts of such Lenders and setting forth the agreement of each Incremental Lender to become a party to this Agreement and to be bound by all the terms and provisions hereof (a "Facility Increase Agreement"), together with a replacement or additional Note, as applicable, evidencing the new Facility Amount of each affected Lender, duly executed and delivered by the Borrower and such evidence of appropriate corporate authorization on the part of the Borrower with respect to the increase in the Aggregate Facility Amount and such opinions of counsel for the Borrower with respect to the increase in the Aggregate Facility Amount as the Agent may reasonably request.

(d) Upon the acceptance of the Facility Increase Agreement by the Agent, the Aggregate Facility Amount shall automatically be increased by the amount of the Facility Amounts added through such Facility Increase Agreement.

(e) Upon any increase in the Aggregate Facility Amount pursuant to this Section 2.16 that is not pro rata among all Lenders, within 5 Business Days, the Borrower shall prepay all Borrowings hereunder in their entirety and, to the extent the Borrower elects to do so and subject to the conditions specified in Section 3.2, the Borrower shall effect new Borrowings from the Lenders in proportion to their respective Facility Amounts after giving effect to such increase.

ARTICLE IV
Representations and Warranties

The Borrower represents and warrants to the Lenders as follows:

Section 4.1 Existence and Power.

The Borrower is a corporation duly incorporated, validly existing and in good standing under the laws of Delaware, and is duly licensed or qualified to transact business in all jurisdictions where the character of the property owned or leased or the nature of the business transacted by it makes such licensing or qualification necessary, except where the failure to be so licensed or qualified (i) will not permanently preclude the Borrower from maintaining any material action in any such jurisdiction even though such action arose in whole or in part during the period of such failure, and (ii) will not result in any other Material Adverse Effect. The Borrower has all requisite power and authority, corporate or otherwise, to conduct its business, to own its properties and to execute and deliver, and to perform all of its obligations under, the Loan Documents.

Section 4.2 Authorization of Borrowing; No Conflict as to Law or Agreements.

The execution, delivery and performance by the Borrower of the Loan Documents and the borrowings from time to time hereunder have been duly authorized by all necessary corporate action and by all necessary public utilities commissions and any other regulatory bodies having jurisdiction over the Borrower (except as noted in Schedule 4.2 to the Agreement with respect to Borrowings made after December 31, 2006), and do not and will not
(i) require any consent or approval of the stockholders of the Borrower, or any authorization, consent or approval by any governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, other than Authorizing Orders set forth in Schedule 4.2 that (except as noted therein with respect to Borrowings made after December 31, 2006) have been obtained and copies of which have been delivered to the Agent pursuant to Section 3.1, (ii) violate any provision of any law, rule or regulation (including, without limitation, Regulation X of the Board of Governors of the Federal Reserve System) or of any order, writ, injunction or decree presently in effect having applicability to the Borrower or of the articles of incorporation or bylaws of the Borrower, (iii) result in a breach of or constitute a default under any indenture or loan or credit agreement or any other agreement, lease or instrument to which the Borrower is a party or by which it or its properties may be bound or affected, or (iv) result in, or require, the creation or imposition of any Lien or other charge or encumbrance of any nature (other than those in favor of the Agent to secure one or more of the Obligations) upon or with respect to any of the properties now owned or hereafter acquired by the Borrower.

Section 4.3 Legal Agreements.

This Agreement and the other Loan Documents constitute, the legal, valid and binding obligations of the Borrower enforceable against the Borrower in accordance with their respective terms, except to the extent that such enforcement may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors' rights generally or by general equitable principles.

Section 4.4 Subsidiaries.

Schedule 4.4 hereto is a complete and correct list of all present Subsidiaries and of the percentage of the ownership of the Borrower or any other Subsidiary in each case as of the date of this Agreement. Except as otherwise indicated in that Schedule, all shares of each Subsidiary owned by the Borrower or by any such other Subsidiary are validly issued and fully paid and nonassessable.

Section 4.5 Financial Condition.

The Borrower has heretofore furnished to the Lenders its audited consolidated financial statement as of December 31, 2004, and its unaudited interim financial statement as of March 31, 2005. Those financial statements fairly present the financial condition of the Borrower and its Subsidiaries on the dates thereof and the results of their operations and cash flows for the periods then ended, and were prepared in accordance with GAAP, except as expressly noted therein.

Section 4.6 Adverse Change.

There has been no material adverse change in the business, properties or condition (financial or otherwise) of the Borrower since the date of the latest financial statement referred to in
Section 4.5.

Section 4.7 Litigation.

Except as set forth in the Borrower's Annual Report on Form 10-K for the year ended December 31, 2004, or in any document subsequently filed pursuant to Section 13, 14 or 15(d) of the Exchange Act, there are no actions, suits or proceedings pending or, to the knowledge of the Borrower, threatened against or affecting the Borrower or the properties of the Borrower, before any court or governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, which, if determined adversely to the Borrower, would have a Material Adverse Effect.

Section 4.8 Environmental Matters.

The Borrower conducts in the ordinary course of business a review of the effect of existing Environmental Laws and existing Environmental Claims on its business, operations and properties and, as a result thereof, the Borrower has reasonably concluded that such Environmental Laws and Environmental Claims could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, exclusive of Environmental Claims as set forth in the Borrower's Annual Report on Form 10-K for the year ended December 31, 2004, or in any document subsequently filed pursuant to Section 13, 14 or 15(d) of the Exchange Act.

Section 4.9 Regulation U.

The Borrower is not engaged in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U of the Board of Governors of the Federal Reserve System), and no part of the proceeds of any Borrowing will be used to purchase or carry any margin stock or to extend credit to others for the purpose of purchasing or carrying any margin stock.

Section 4.10 Taxes.

The Borrower has filed all federal and other tax returns and reports required to be filed, and has paid all federal and other taxes, assessments, fees and other governmental charges levied or imposed upon it or its properties, income or assets otherwise due and payable, except those which are being contested in good faith by appropriate proceedings and for which adequate reserves have been provided in accordance with GAAP and except those the failure to file or pay which would not have a Material Adverse Effect. There is no proposed tax assessment against the Borrower that would, if made, have a Material Adverse Effect.

Section 4.11 Titles and Liens.

To the Borrower's knowledge, without having undertaken any search of real property records for this purpose, the Borrower has good and sufficient title to, or valid leasehold interests in, all real property necessary or used in the ordinary conduct of its business, and good title to all other property and assets reflected in the Borrower's most recent consolidated financial statements provided to the Lenders as owned by the Borrower, except for such defects in title as could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect and other than any sold, as permitted by Section 6.4. As of the date of this Agreement, the property of the Borrower is subject to no Liens other than a permitted pursuant to Section 6.1.

Section 4.12 Intellectual Property.

The Borrower owns or is licensed or otherwise has the right to use all of the patents, trademarks, service marks, trade names, copyrights, contractual franchises, authorizations and other rights that are reasonably necessary for the operation of its business, without conflict with the rights of any other Person, except to the extent that noncompliance would not have a Material Adverse Effect. To the knowledge of the Borrower, no slogan or other advertising device, product, process, method, substance, part or other material now employed, or now contemplated to be employed, by the Borrower infringes upon any rights held by any other Person, except to the extent that noncompliance would not have a Material Adverse Effect. No claim or litigation regarding any of the foregoing is pending or threatened, and no patent, invention, device, application, principle or any statute, law, rule, regulation, standard or code is pending or, to the knowledge of the Borrower, proposed, which, in either case, could reasonably be expected to have a Material Adverse Effect.

Section 4.13 ERISA.

(a) Each Plan is in compliance in all material respects with ERISA, the Code and other applicable federal or state law. Each Plan which is intended to qualify under
Section 401(a) of the Code has received a favorable determination letter from the Internal Revenue Service and, to the best knowledge of the Borrower, nothing has occurred which would or could reasonably be expected to cause the loss of such qualification of any such Plan or related trust.

(b) There are no pending or, to the best knowledge of the Borrower, threatened claims (other than routine claims for benefits in the ordinary course), actions or lawsuits, or action by any governmental authority, with respect to any Plan which has resulted or could reasonably be expected to result in a Material Adverse Effect. To the best knowledge of the Borrower, there has been no prohibited transaction within the meaning of Section 4975 of the Code or Section 406 ERISA or other material violation of the fiduciary responsibility rules with respect to any Plan which has resulted or could reasonably be expected to result in a Material Adverse Effect.

(c) No Reportable Event has occurred or is reasonably expected to occur with respect to any Pension Plan.

(d) The aggregate Unfunded Pension Liability for all Pension Plans (calculated based on the most recent actuarial report for each Pension Plan) does not exceed $15,000,000.

(e) Neither the Borrower nor any ERISA Affiliate has incurred nor does it reasonably expect to incur, any liability under Title IV of ERISA with respect to any Pension Plan (other than premiums due and not delinquent under Section 4007 of ERISA).

(f) Neither the Borrower nor any ERISA Affiliate has transferred any Unfunded Pension Liability to any Person or otherwise engaged in a transaction that could be subject to
Section 4069 of ERISA.

(g) Neither the Borrower nor any ERISA Affiliate has incurred nor reasonably expects to incur any liability, other than Acquisition Liability (and no event has occurred which, with the giving of notice under Section 4219 of ERISA, would result in such liability), under Section 4201 or 4243 of ERISA with respect to a Multiemployer Plan. As used in this paragraph, "Acquisition Liability" means liability immaterial to the Borrower, its business and operations when taken as a whole that is incurred in connection with an acquisition by the Borrower or any ERISA Affiliate.

(a) The Agent may, by notice to the Borrower, declare the Facility to be terminated, whereupon the same shall forthwith terminate.

(b) The Agent may, by notice to the Borrower, declare the entire unpaid principal amount of the Notes then outstanding, all interest accrued and unpaid thereon, and all other amounts payable under this Agreement to be forthwith due and payable, whereupon the Notes, all such accrued interest and all such amounts shall become and be forthwith due and payable, without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by the Borrower.

(c) The Lenders may exercise any other rights and remedies available to them by law or agreement.

Notwithstanding the foregoing, upon the occurrence of an Event of Default described in Section 7.1(g) or 7.1(h) hereof, the entire unpaid principal amount of the Notes then outstanding, all interest accrued and unpaid thereon, and all other amounts payable under this Agreement shall be immediately due and payable without presentment, demand, protest or notice of any kind.

ARTICLE VIII
The Agent

Section 8.1 Authorization.

Each Lender and the holder of each Note irrevocably appoints and authorizes the Agent to act on behalf of such Lender or holder to the extent provided herein or in any document or instrument delivered hereunder or in connection herewith, and to take such other action as may be reasonably incidental thereto. In furtherance of the foregoing, and not in limitation thereof, each Lender irrevocably (i) authorizes the Agent to execute and deliver and perform its obligations under this Agreement and each of the Loan Documents to which the Agent is a party, and to exercise all rights, powers and remedies that the Agent may have hereunder or thereunder, (ii) appoints the Agent as nominal beneficiary or nominal secured party, as the case may be, under the Loan Documents and all related UCC-1 financing statements, and (iii) authorizes the Agent to act as agent of and for such Lender for purposes of holding, perfecting and disposing of any collateral under the Loan Documents. As to any matters not expressly provided for by this Agreement or the Loan Documents, the Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Lenders or, if so required pursuant to Section 9.2, upon the instructions of all Lenders; provided, however, that except for action expressly required of the Agent hereunder, the Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action, and the Agent shall not in any event be required to take any action which is contrary to this Agreement, the Loan Documents or applicable law. The Agent shall not have a fiduciary relationship in respect of the Borrower or any Lender by reason of this Agreement.

Section 8.2 Distribution of Payments and Proceeds.

(a) After deduction of any costs of collection, as provided in this Agreement and the other Loan Documents, and any fee payable to the Agent in its capacity as such under this Agreement, any Fee Letter or any other agreement, the Agent shall remit to each Lender that Lender's Percentage of all payments of principal and interest and of all fees and other amounts payable hereunder for the benefit of the Lenders that are received by the Agent under the Loan Documents. Each Lender's interest in the Loan Documents shall be payable solely from payments, collections and proceeds actually received by the Agent under the Loan Documents; and the Agent's only liability to the Lenders hereunder shall be to account for each Lender's Percentage of such payments, collections and proceeds in accordance with this Agreement. If the Agent is ever required for any reason to refund any such payments, collections or proceeds, each Lender will refund to the Agent, upon demand, its Percentage of such payments, collections or proceeds, together with its Percentage of interest or penalties, if any, payable by the Agent in connection with such refund.

(b) Notwithstanding the foregoing, if any Lender has wrongfully refused to fund its Percentage of any Borrowing or other Advance as required hereunder, or if the principal balance of any Lender's Note is for any other reason less than its Percentage of the aggregate principal balances of the Notes then outstanding, the Agent may remit all payments received by it to the other Lenders until such payments have reduced the aggregate amounts owed by the Borrower to the extent that the aggregate amount owing to such Lender hereunder is equal to its Percentage of the aggregate amount owing to all of the Lenders hereunder. The provisions of this paragraph are intended only to set forth certain rules for the application of payments, proceeds and collections in the event that a Lender has breached its obligations hereunder and shall not be deemed to excuse any Lender from such obligations.

Section 8.3 Expenses.

All payments, collections and proceeds received or effected by the Agent may be applied, first, to pay or reimburse the Agent for all costs, expenses, damages and liabilities at any time incurred by or imposed upon the Agent in connection with this Agreement or any other Loan Document (including but not limited to all reasonable attorney's fees, foreclosure expenses and advances made to protect the security of any collateral). If the Agent does not receive payments, collections or proceeds sufficient to cover any such costs, expenses, damages or liabilities within 30 days after their incurrence or imposition, each Lender shall, upon demand, remit to the Agent its Percentage of the difference between (i) such costs, expenses, damages and liabilities, and (ii) such payments, collections and proceeds, together with interest on such amount for each day following the thirtieth day after demand therefor until so remitted at a rate equal to the Federal Funds Rate for each such day.

Section 8.4 Payments Received Directly by Lenders.

If any Lender or other holder of a Note shall obtain any payment or other recovery (whether voluntary, involuntary, by application of offset or otherwise) on account of the Obligations other than through distributions made in accordance with Section 8.2, such Lender or holder shall promptly give notice of such fact to the Agent and shall purchase from the other Lenders or holders such participations in the Obligations held by them as shall be necessary to cause the purchasing Lender or holder to share the excess payment or other recovery ratably with each of them; provided, however, that if all or any portion of the excess payment or other recovery is thereafter recovered from such purchasing Lender or holder, the purchase shall be rescinded and the purchasing Lender restored to the extent of such recovery (but without interest thereon).

Section 8.5 Indemnification.

Each Lender severally (but not jointly) hereby agrees to indemnify and hold harmless the Agent, as well as the Agent's agents, employees, officers and directors, ratably according to their respective Percentages from and against any and all losses, liabilities (including liabilities for penalties), actions, suits, judgment, demands, damages, costs, disbursements, or expenses (including attorneys' fees and expenses) of any kind or nature whatsoever, which are imposed on, incurred by, or asserted against the Agent or its agents, employees, officers or directors in any way relating to or arising out of this Agreement or the Loan Documents, or as a result of any action taken or omitted to be taken by the Agent; provided, however, that no Lender shall be liable for any portion of any such losses, liabilities (including liabilities for penalties), actions, suits, judgments, demands, damages, costs disbursements, or expenses resulting from the gross negligence or willful misconduct of the Agent. Notwithstanding any other provision of the Loan Documents, the Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action.

Section 8.6 Exculpation.

The Agent shall not be liable for any action taken or omitted to be taken by the Agent in connection with this Agreement or the Loan Documents, except for its own gross negligence or willful misconduct. The Agent shall be entitled to rely upon advice of counsel concerning legal matters, the advice of independent public accountants with respect to accounting matters and advice of other experts as to any other matters, and upon this Agreement, any Loan Document and any schedule, certificate, statement, report, notice or other writing which it believes to be genuine or to have been presented by a proper person. Neither the Agent nor any of its directors, officers, employees or agents shall (a) be responsible for any recitals, representations or warranties contained in, or for the execution, validity, genuineness, effectiveness or enforceability of this Agreement, any Loan Document, or any other instrument or document delivered hereunder or in connection herewith, (b) be responsible for the validity, genuineness, perfection, effectiveness, enforceability, existence, value or enforcement of any collateral security, (c) be under any duty to inquire into or pass upon any of the foregoing matters, or to make any inquiry concerning the performance by the Borrower or any other obligor of its obligations, or (d) in any event, be liable as such for any action taken or omitted by it or them, except for its or their own gross negligence or willful misconduct. The agency hereby created shall in no way impair or affect any of the rights and powers of, or impose any duties or obligations upon, the Agent in its individual capacity.

Section 8.7 Agent and Affiliates.

The Agent shall have the same rights and powers hereunder in its individual capacity as any other Lender, and may exercise or refrain from exercising the same as though it were not the Agent, and the Agent and its affiliates may accept deposits from and generally engage in any kind of business with the Borrower as fully as if the Agent were not the Agent hereunder.

Section 8.8 Credit Investigation.

Each Lender acknowledges that it has made such inquiries and taken such care on its own behalf as would have been the case had its obligations hereunder been incurred and the Advances made directly by such Lender to the Borrower without the intervention of the Agent or any other Lender. Each Lender agrees and acknowledges that the Agent makes no representations or warranties about the creditworthiness of the Borrower or any other party to this Agreement or with respect to the legality, validity, sufficiency or enforceability of this Agreement, any Loan Document, or any other instrument or document delivered hereunder or in connection herewith.

Section 8.9 Resignation and Assignment of Agent.

(a) The Agent may resign as such at any time upon at least 30 days' prior notice to the Borrower and the Lenders. In the event of any resignation of the Agent, the Required Lenders shall as promptly as practicable appoint a successor Agent. If no such successor Agent shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the resigning Agent's giving of notice of resignation, then the resigning Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be a commercial bank organized under the laws of the United States of America or of any State thereof. Any such successor Agent shall have capital and retained earnings of at least $100,000,000.

(b) The Agent may, without the consent of the Borrower or the other Lenders, assign its rights and obligations as Agent hereunder and under the other Loan Documents to its parent or to any wholly owned subsidiary of its parent, and upon such assignment, the former Agent shall be deemed to have retired, and such wholly owned subsidiary shall be deemed to be a successor Agent. Any such successor Agent shall have capital and retained earnings of at least $100,000,000.

(c) Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon be entitled to receive from the prior Agent such documents of transfer and assignment as such successor Agent may reasonably request and the resigning or assigning Agent shall be discharged from its duties and obligations under this Agreement. After any resignation or assignment pursuant to this Section, the provisions of this Section shall inure to the benefit of the retiring Agent as to any actions taken or omitted to be taken by it while it was acting as Agent hereunder.

Section 8.10 Defaults.

The Agent shall not be deemed to have knowledge of the occurrence of a Default or an Event of Default unless the Agent has received notice from a Lender or the Borrower specifying the occurrence of such Default or Event of Default. In the event that the Agent receives such a notice of the occurrence of a Default or an Event of Default, the Agent shall give prompt notice thereof to the Lenders. The Agent shall (subject to Section 8.5 hereof) take such actions with respect to such Default as shall be directed by the Required Lenders; provided that, unless and until the Agent shall have received such directions, the Agent may take any action, or refrain from taking any action, with respect to such Default as it shall deem advisable in the best interest of the Lenders.

Section 8.11 Obligations Several.

The obligations of each Lender hereunder are the several obligations of such Lender, and neither any Lender nor the Agent shall be responsible for the obligations of any other Lender hereunder, nor will the failure by the Agent or any Lender to perform any of its obligations hereunder relieve the Agent or any other Lender from the performance of its respective obligations hereunder. Nothing contained in this Agreement, and no action taken by any Lender or the Agent pursuant hereto or in connection herewith or pursuant to or in connection with the Loan Documents shall be deemed to constitute the Lenders, together or with or without the Agent, as a partnership, association, joint venture, or other entity.

ARTICLE IX
Miscellaneous

Section 9.1 No Waiver; Cumulative Remedies.

No failure or delay on the part of the Lenders in exercising any right, power or remedy under the Loan Documents shall operate as a waiver thereof; nor shall any Lender's acceptance of payments while any Default or Event of Default is outstanding operate as a waiver of such Default or Event of Default, or any right, power or remedy under the Loan Documents; nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy under the Loan Documents.

(i) personally delivered, (ii) transmitted by registered mail, postage prepaid, (iii) sent by Federal Express or similar expedited delivery service, or (iv) transmitted by telecopy, in each case addressed to the party to whom notice is being given at its address or telecopier number (as the case may be) as set forth in Exhibit A or in any applicable Assignment Certificate; or, as to each party, at such other address or telecopier number as may hereafter be designated in a notice by that party to the other party complying with the terms of this Section. All such notices or other communications shall be deemed to have been given on (i) the date received if delivered personally or by mail, (ii) the date of receipt, if delivered by Federal Express or similar expedited delivery service, or (iii) the date of transmission if delivered by telecopy, except that notices or requests to the Agent or any Lender pursuant to any of the provisions of Article II shall not be effective until received.

Section 9.4 Costs and Expenses.

The Borrower agrees to pay on demand all reasonable costs and expenses incurred by the Agent in connection with the negotiation, preparation, execution, administration, amendment or enforcement of the Loan Documents and the other instruments and documents to be delivered hereunder and thereunder, including the reasonable fees and out-of-pocket expenses of counsel for any Lender with respect thereto, whether paid to outside counsel or allocated to the Agent by in-house counsel.

Section 9.5 Indemnification by Borrower.

The Borrower hereby agrees to indemnify the Agent and the Lenders and each officer, director, employee and agent thereof (herein individually each called an "Indemnitee" and collectively called the "Indemnitees") from and against any and all losses, claims, damages, reasonable expenses (including, without limitation, reasonable attorneys' fees) and liabilities incurred by an Indemnitee in connection with or arising out of the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the use of the proceeds of any Borrowing hereunder (including but not limited to any such loss, claim, damage, expense or liability arising out of any claim in which it is alleged that any Environmental Law has been breached with respect to any activity or property of the Borrower), except to the extent that such loss, claim, damage, expense or liability was incurred as a result of the gross negligence or willful misconduct of the applicable Indemnitee. All obligations provided for in this Section shall survive any termination of this Agreement.

Section 9.6 Execution in Counterparts.

This Agreement and the other Loan Documents may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which counterparts of this Agreement or such other Loan Document, as the case may be, taken together, shall constitute but one and the same instrument.

Section 9.7 Binding Effect; Assignment and Participations.

(a) Generally. The Loan Documents shall be binding upon and inure to the benefit of the Borrower and the Lenders and their respective successors and assigns, except that (i) the Borrower shall not have the right to assign its rights thereunder or any interest therein without the prior written consent of each of the Lenders, and (ii) except as set forth in this Section 9.7, no Lender may assign or grant any participation in any of its rights or obligations under any Loan Document.

(b) Participations. Any Lender may, at any time, grant participations in a portion of its Note and Commitment to any institutional investor on any date selected by such Lender. Any Lender proposing a participation hereunder shall give notice of such participation to the Agent at least ten Business Days prior to such participation (unless the Agent consents to a shorter period of time). Such notice shall specify the identity of the proposed purchaser of the participation and the amount of the proposed participation. No such partial participation shall be permitted if the principal amount thereof would be less than $5,000,000. No holder of any such participation, other than an affiliate of such Lender, shall be entitled to require such Lender to take or omit to take any action hereunder, except that such Lender may agree with such participant that such Lender will not, without such participant's consent, (i) forgive any indebtedness of the Borrower under this Agreement or the Notes, (ii) agree to reduce the rate of interest charged under this Agreement, or (iii) agree to extend the final maturity of any indebtedness evidenced by the Notes, except as expressly provided by the terms of the Loan Documents. No Lender shall, as between the Borrower and such Lender, be relieved of any of its obligations hereunder as a result of any such granting of a participation. The Borrower hereby acknowledges and agrees that any participant described in this Section will, for purposes of Section 2.10(b), be considered to be a Lender hereunder (provided that such participant shall not be entitled to receive any more than the Lender selling such participation would have received had such sale not taken place) and may rely on, and possess all rights under, any opinions, certificates, or other instruments or documents delivered under or in connection with any Loan Document (it being understood that each opinion delivered hereunder speaks only as of the date thereof).

(c) Assignments. Any Lender may, at any time, assign a portion of its Note and Commitment to an Eligible Lender (an "Applicant") on any date (the "Adjustment Date") selected by such Lender. Any Lender proposing an assignment hereunder shall give notice of such assignment to the Agent at least ten Business Days prior to such assignment (unless the Agent consents to a shorter period of time). Such notice shall specify the identity of such Applicant and the Percentage which it proposes that such Applicant acquire (which Percentage shall be the same for the Commitment and the Note held by the assigning Lender). No such partial assignment shall be permitted if, immediately after giving effect to such assignment, either the Credit Exposure of the Applicant or the Credit Exposure of the assigning Lender would be less than $5,000,000. The notice of assignment shall contain a representation by the Applicant to the effect that none of the consideration used to make the purchase of the Note and Commitment under the applicable assignment agreement constitutes "plan assets" as defined under ERISA and that the rights and interests of the Applicant in and under the Loan Documents will not be "plan assets" under ERISA. Any Lender making an assignment under this Section shall pay the Agent a transfer fee in the amount of $3,500 simultaneously with such assignment.

(d) Consents. Any assignment hereunder may be made, and any participation granted, only with the prior written consent of the Agent and the Borrower; provided, however, that (i) in no event shall such consent be unreasonably withheld, (ii) the consent of the Borrower shall not be required if any Default or Event of Default has occurred and is continuing at the time of such assignment or grant of participation, (iii) no such consent of the Borrower and the Agent shall be required for the assignment by any Lender of, or grant of a participation in, all or any part of its Commitment and Note to one or more other Persons that are Lenders immediately prior to such assignment, and (iv) no such consent of the Borrower and the Agent shall be required for the assignment by any Lender of, or grant of a participation in, all or any part of its Commitment and Note to one or more affiliates of such Lender, provided that, unless consented to by the Borrower and the Agent (which consent shall not be unreasonably withheld), no such assignment under this clause (iv) shall relieve the transferring Lender from its obligations hereunder.

(e) Assignment Certificate and Notes. To confirm the status of each Additional Lender as a party to this Agreement and to evidence the assignment in accordance herewith:

(i) the Borrower, such Lender, such Applicant, and the Agent shall, on or before the Adjustment Date, execute and deliver to the Agent an Assignment Certificate in substantially the form of Exhibit D (an "Assignment Certificate") (provided that the assignment will be effective without the signature of the Borrower or the Agent to the extent that the consent of the Borrower or the Agent, as the case may be, is not required hereunder); and

(ii) the Borrower will, at its own expense, execute and deliver to the Additional Lender a new Note, payable to the order of the Additional Lender in an amount corresponding to the applicable interest in the assigning Lender's rights and obligations acquired by such Applicant pursuant to such assignment, and, if the assigning Lender has retained interests in such rights and obligations, a new Note, payable to the order of that Lender in an amount corresponding to such retained interests.

(a) Purchaser shall be entitled to all (i) Hydrocarbons produced from or attributable to the Properties at and after the Effective Time, (ii) proceeds from the sale of Hydrocarbons at and after the Effective Time and
(iii) other income, proceeds, receipts and credits earned with respect to the Assets at or after the Effective Time. Purchaser shall be liable and responsible for (and entitled to any refunds with respect to) all Property Costs incurred at and after the Effective Time.

(b) Seller shall be entitled to all (i) Hydrocarbons produced from or attributable to the Properties prior to the Effective Time, (ii) proceeds from the sale of Hydrocarbons prior to the Effective Time and (iii) other income, proceeds, receipts and credits earned with respect to the Assets prior to the Effective Time. Seller shall be liable and responsible for (and entitled to any refunds with respect to) all Property Costs incurred prior to the Effective Time.

(c) Right-of-way fees, insurance premiums and other Property Costs that are paid periodically and cannot be accurately identified as being incurred when paid shall be prorated based on the number of days in the applicable period falling before and the number of days in the applicable period falling at or after the Effective Time.

(d) Ad valorem, production, severance and similar Taxes shall be prorated based on the number of units actually produced, purchased or sold or proceeds of sale, as applicable, before, and at or after, the Effective Time. In each case, Purchaser shall be responsible for the portion allocated to the period at and after the Effective Time, and Seller shall be responsible for the portion allocated to the period before the Effective Time.

(e) For purposes of allocating production (and accounts receivable with respect thereto), under this Section 1.6, (i) liquid Hydrocarbons shall be deemed to be "from or attributable to" the Properties when they pass through the pipeline connecting into the storage facilities into which they are run and (ii) gaseous Hydrocarbons shall be deemed to be "from or attributable to" the Properties when they pass through the delivery point sales meters on the pipelines through which they are transported. Seller shall utilize reasonable interpolative procedures to arrive at an allocation of production when exact meter readings or gauging and strapping data is not available. Seller shall provide to Purchaser, no later than four (4) Business Days prior to Closing, all data necessary to support any estimated allocation, for purposes of establishing the adjustment to the Purchase Price pursuant to Section 2.2 hereof that will be used to determine the Closing Payment.

ARTICLE 2
PURCHASE PRICE

Section 2.1 Purchase Price.

The purchase price for the Assets (the "Purchase Price") shall be Seventy Million Seventy One Thousand Seven Hundred Sixty Four Dollars (U.S. $70,071,764.00) adjusted as provided in Section 2.2.

Section 2.2 Adjustments to Purchase Price.

The Purchase Price for the Assets shall be adjusted as follows:

(a) Reduced by the aggregate amount of the proceeds received by Seller from the sale of Hydrocarbons and other proceeds earned and attributable to the Assets during the Adjustment Period;

(b) Reduced in accordance with Section 3.5, by an amount equal to the Allocated Value of those Properties (i) with respect to which preferential purchase rights have been exercised prior to Closing or (ii) that cannot be transferred at Closing because consents to the assignments of those Properties have not been obtained;

(c) Reduced by the aggregate amounts payable to owners of working interests, royalties and overriding royalties and other interests in the Properties held in suspense by Seller as of the Closing Date unless the suspended funds are transferred by Seller to Purchaser on the Closing Date;

(d) Reduced by Seller's pro-rata share of ad valorem taxes;

(e) Reduced in accordance with Article 3 by amounts as remedies for Title Defects;

(f) Reduced in accordance with Article 4 pursuant to
Section 4.3 regarding environmental matters;

(g) Increased by the amount of all Property Costs which have been paid by Seller and incurred during the Adjustment Period, except for any Property Costs and other such costs already deducted in the determination of proceeds in Section 2.2(a);

(h) Increased or decreased, as appropriate, pursuant to the provisions of Section 7.8 dealing with gas imbalances and/or take-or-pay make-up obligations; and

(i) Increased by the amount of any Title Benefit pursuant to Section 3.4(e).

(j) Increased or decreased by other amounts mutually agreed to by Seller and Purchaser.

All such adjustments shall be determined in accordance with generally accepted accounting principles and Council of Petroleum Accountants Society (COPAS) standards.

The adjustment described in Section 2.2(a) shall serve to satisfy, up to the amount of the adjustment, Purchaser's entitlement under Section 1.6 to Hydrocarbon production from or attributable to the Properties during the Adjustment Period, and to the other income, proceeds, receipts and credits earned with respect to the Assets during the Adjustment Period. Purchaser shall not have any separate rights to receive any production or income, proceeds, receipts and credits with respect to which an adjustment has been made. Similarly, the adjustment described in Section 2.2(g) shall serve to satisfy, up to the amount of the adjustment, Purchaser's obligation under Section 1.6 to pay Property Costs and other costs attributable to the ownership and operation of the Assets which are incurred during the Adjustment Period. Purchaser shall not be separately obligated to pay for any Property Costs or other such costs with respect to which an adjustment has been made.

Section 2.3 Allocation of Purchase Price.

(a) Simultaneous with the execution of this Agreement, Purchaser will deliver to Seller a draft allocation of the unadjusted Purchase Price among each of the Assets, which has been made in compliance with the principles of Section 1060 of the Internal Revenue Code of 1986, as amended (the "Code"), and the Treasury regulations thereunder. Within two (2) Business Days after Seller has received Purchaser's draft allocation, Seller and Purchaser will attempt to agree on the final allocation of the unadjusted Purchase Price among each of the Assets; provided, however, that in no event shall any such allocation of value be deemed final until Seller and Purchaser have approved the same in writing. Once approved by all parties, such allocation of value shall be attached to this Agreement as Exhibit 2.3. The "Allocated Value" for any Asset shall equal the portion of the unadjusted Purchase Price allocated to such Asset on Exhibit 2.3, increased or decreased by its respective proportionate share of the price adjustments described in Section
2.2. After Seller and Purchaser have agreed on the Allocated Values for the Assets, Seller and Purchaser will be deemed to have accepted such Allocated Values for purposes of this Agreement and the transactions contemplated hereby. Seller, however, makes no representation or warranty to Purchaser as to the accuracy of such values. Seller and Purchaser agree (i) that the Allocated Values shall be used by Seller and Purchaser as the basis for notices to holders of preferential rights to purchase and (ii) that neither Seller nor Purchaser will take positions inconsistent with the Allocated Values in notices to government authorities, in audit or other proceedings with respect to Taxes, in notices to holders of preferential rights to purchase. Purchaser and Seller further agree that, on or before the Closing Date, they will mutually agree as to the further allocation of the Allocated Values included in Exhibit 2.3 as to the relative portion of those values attributable to leasehold costs and depreciable Equipment.

(b) In the event that Seller and Purchaser are unable to agree as to the Allocated Values, at the sole election of Seller, (i) this Agreement may be terminated unilaterally by Seller, in which case Purchaser shall be entitled to an immediate refund of the Deposit from Seller, or (ii) the dispute may be submitted to arbitration as provided in Section 7.15 below.

Section 2.4 Deposit.

Concurrently with the execution of this Agreement, Purchaser shall wire transfer to Seller an earnest money deposit in an amount equal to five percent (5 %) of the Purchase Price (the "Deposit"). The Deposit shall be applied against the Purchase Price if the Closing occurs or shall be otherwise distributed in accordance with the terms of this Agreement.

ARTICLE 3
TITLE MATTERS

Section 3.1 Seller's Title.

(a) Seller represents and warrants to Purchaser that Seller's title to the Wells shown on Exhibit 1.2(b) and the Units shown on Exhibit 1.2 (c) as of the Effective Time is (and as of the Closing Date shall be) Defensible Title.

(b) The Assignment and Bill of Sale to be delivered by Seller to Purchaser shall be in form identical to the assignment shown on Exhibit 3.1(b) attached hereto and shall contain a special warranty of title by, through and under Seller, but not otherwise, to the Leases shown on Exhibit 1.2(a), subject to the Permitted Encumbrances. Otherwise, the Assignment and Bill of Sale shall be without warranty of title, express, implied, statutory or otherwise. The Assignment and Bill of Sale shall transfer to Purchaser all rights or actions on title warranties given or made by Seller's predecessors (other than Affiliates of Seller), to the extent Seller may legally transfer such rights.

(c) Purchaser shall not be entitled to protection under Seller's special warranty of title in the Assignment and Bill of Sale against any Title Defect reported by Purchaser to Seller under this Article 3. All reported Title Defects shall be covered by the provisions of Article 3 and are expressly excluded from protection under Seller's special warranty of title in the Assignment and Bill of Sale.

Section 3.2 Defensible Title.

As used in this Agreement, the term "Defensible Title" means that title of Seller which, subject to Permitted Encumbrances:

(a) Entitles Seller to receive a share of the Hydrocarbons produced, saved and marketed from any Unit or Well throughout the duration of the productive life of such Unit or Well after satisfaction of all royalties, overriding royalties, nonparticipating royalties, net profits interests or other similar burdens on or measured by production of Hydrocarbons (a "Net Revenue Interest") of not less than the Net Revenue Interest share shown in Exhibit 1.2(b) for the Wells and Exhibit 1.2(c) for the Units, except decreases in connection with those operations in which Seller may after the Effective Time be a non-consenting co-owner, decreases resulting from the establishment or amendment after the Effective Time of units, and decreases required to allow other working interest owners to make up past underproduction or pipelines to make up past under deliveries;

(b) Obligates Seller to bear a percentage of the Property Costs relating to any Unit or Well not greater than the "Working Interest" shown in Exhibit 1.2(b) for Wells and Exhibit 1.2(c) for Units without increase throughout the productive life of such Wells or Units except increases resulting from contribution requirements with respect to defaulting co-owners under applicable operating agreements and increases that are accompanied by at least a proportionate increase in Seller's Net Revenue Interest; and

(c) Is free and clear of liens, encumbrances, obligations, security interests, pledges or other defects.

The term "Title Defect" shall mean any liens, encumbrances, obligations, security interests, pledges or other defects, including, without limitation, discrepancies in Net Revenue Interest or Working Interest, that cause a breach of Seller's representation and warranty of Defensible Title in
Section 3.1(a).

The term "Title Benefit" shall mean any right, circumstance or condition that operates to increase the Net Revenue Interest of Seller in any Property above that shown on Exhibit 1.2(b) and Exhibit 1.2(c), without causing a greater than proportionate increase in Seller's Working Interest above that shown in Exhibit 1.2(b) and Exhibit 1.2(c).

Section 3.3 Permitted Encumbrances.

As used herein, the term "Permitted Encumbrances" shall mean any or all of the following:

(a) Royalties and any overriding royalties, reversionary interests and other burdens to the extent that they do not, individually or in the aggregate, reduce Seller's Net Revenue Interest below that shown in Exhibit 1.2(b) and Exhibit 1.2(c) or increase Seller's Working Interest above that shown in Exhibit 1.2(b) and Exhibit 1.2(c) without a corresponding increase in the Net Revenue Interest;

(b) All Leases, unit agreements, pooling agreements, operating agreements, production sales contracts, division orders and other Contracts applicable to the Assets, to the extent that they do not, individually or in the aggregate, reduce Seller's Net Revenue Interest below that shown in Exhibit 1.2(b) and Exhibit 1.2(c) or increase Seller's Working Interest above that shown in Exhibit 1.2(b) and Exhibit 1.2(c) without a corresponding increase in the Net Revenue Interest;

(c) Preferential rights to purchase the Assets with respect to which, prior to Closing, (i) waivers are obtained from the holders of such preferential rights to purchase and/or (ii) the appropriate time period for asserting such rights has expired without an exercise of such rights;

(d) Third-party consent to assignment requirements and similar restrictions with respect to which waivers or consents are obtained by Seller from the appropriate parties prior to the Closing Date or the appropriate time period for asserting the right has expired or which need not be satisfied prior to a transfer;

(e) Liens for current Taxes or assessments not yet delinquent or, if delinquent, being contested in good faith by appropriate actions;

(f) Liens or charges arising in the ordinary course of business for amounts not yet delinquent (including any amounts being withheld as provided by law), or if delinquent, being contested in good faith by appropriate actions;

(g) All rights to consent, by required notices to, filings with, or other actions by Governmental Bodies in connection with the sale or conveyance of oil and gas leases or interests therein if they are not required prior to the sale or conveyance;

(h) Rights of reassignment arising upon final intention to abandon or release the Assets, or any of them;

(i) Easements, rights-of-way, servitudes, permits, surface leases and other rights in respect of surface operations to the extent that they do not, individually or in the aggregate, reduce Seller's Net Revenue Interest below that shown in Exhibits 1.2(b) and Exhibit 1.2(c) or increase Seller's Working Interest above that shown in Exhibits 1.2(b) and Exhibit 1.2(c) without a corresponding increase in Net Revenue Interest;

(j) Calls on production under existing Contracts;

(k) All rights reserved to or vested in any Governmental Body to control or regulate any of the Assets in any manner and all obligations and duties under all applicable laws, rules and orders of any such Governmental Body or under any franchise, grant, license or permit issued by any such Governmental Body;

(l) Any encumbrance affecting the Assets which is discharged by Seller prior to or at Closing or which is expressly assumed, bonded or paid by Purchaser prior to or at Closing;

(m) Any matters shown on Exhibit 1.2(a), Exhibit 1.2(b) and Exhibit 1.2(c); and

(n) Any other liens, charges, encumbrances, defects or irregularities which do not, individually or in the aggregate, materially detract from the value of or materially interfere with the use or ownership of the Assets subject thereto or affected thereby (as currently used or owned), which would be accepted by a reasonably prudent Purchaser engaged in the business of owning and operating oil and gas Assets, and which do not reduce Seller's Net Revenue Interest below that shown in Exhibit 1.2(b) and Exhibit 1.2(c), or increase Seller's Working Interest above that shown in Exhibit 1.2(b) and Exhibit 1.2(c) without a corresponding increase in Net Revenue Interest.

Section 3.4 Notice of Title Defects.

(a) To assert a claim arising out of a breach of Seller's representation and warranty of Defensible Title in Section 3.1(a), Purchaser must deliver claim notices to Seller (each a "Title Defect Notice") on or before ten (10) Business Days prior to the Closing Date (the "Title Claim Date"), except as otherwise provided in Sections 3.5, 3.6 or 3.7. Each Title Defect Notice shall be in writing and shall include (i) a description of the alleged Title Defect(s), (ii) the Leases, Units or Wells affected by the Title Defect (each a "Title Defect Property"), (iii) the Allocated Values of each Title Defect Property, (iv) supporting documents reasonably necessary for Seller (as well as any title attorney or examiner hired by Seller) to verify the existence of the alleged Title Defect(s) and (v) the amount by which Purchaser reasonably believes the Allocated Values of each Title Defect Property are reduced by the alleged Title Defect(s) and the computations and information upon which Purchaser's belief is based. Purchaser shall be deemed to have waived all breaches of Seller's representation and warranty of Defensible Title in Section 3.1(a) of which Seller has not been given notice on or before the Title Claim Date.

(b) Seller shall have the right, but not the obligation, to deliver to Purchaser on or before the Title Claim Date with respect to each Title Benefit a notice (a "Title Benefit Notice") including (i) a description of the Title Benefit, (ii) the Leases, Units or Wells affected, (iii) the Allocated Values of the Units or Wells subject to such Title Benefit and
(iv) the amount by which the Seller reasonably believes the Allocated Value of those Units or Wells is increased by the Title Benefit, and the computations and information upon which Seller's belief is based. Seller shall be deemed to have waived all Title Benefits of which it has not given notice on or before the Title Claim Date.

(c) In the event that Seller receives a Title Defect Notice, Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure or remove any Title Defects of which it has been advised by Purchaser in the Title Defect Notice prior to Closing.

(d) Remedies for Title Defects.

In the event that any Title Defect is not waived by Purchaser or cured on or before Closing, Seller shall, at its sole election, select one of the following options which shall apply regarding uncured Title Defects:

(i) The Purchase Price shall be reduced by an amount agreed upon ("Title Defect Amount") pursuant to Section 3.4(g) or 3.4(i) by Purchaser and Seller as being the value of such Title Defect, taking into consideration the Allocated Value of the Property subject to such Title Defect, the portion of the Property subject to such Title Defect and the legal effect of such Title Defect on the Property affected thereby;

(ii) Purchaser and Seller shall enter into a separate written agreement whereby Seller will as soon as reasonably practicable after Closing, at the sole cost and expense of Seller, cure or remove such Title Defects to Purchaser's reasonable satisfaction; or

(iii) Seller shall retain the affected Property, in which event the affected Property shall be deleted from this Agreement and the Purchase Price shall be reduced by an amount equal to the Allocated Value of such affected Property.

In the event that Seller elects to proceed under
Section 3.4(d)(i) and, after a reasonable time for good faith negotiation, Purchaser and Seller have failed to agree on the amount by which the Purchase Price should be reduced by Closing, then in such event, Seller, at Seller's sole election, may select one of the other options in 3.4(d), unilaterally terminate this Agreement, in which case Purchaser shall be entitled to an immediate refund of the Deposit from Seller, or the dispute may be submitted to arbitration as provided in
Section 7.15.

(e) With respect to each Unit or Well affected by Title Benefits reported under Section 3.4(b), the Purchase Price shall be increased by an amount (the "Title Benefit Amount") equal to the increase in the Allocated Value for such Unit or Well caused by such Title Benefits, as determined pursuant to Section 3.4(h). The Closing Payment shall be increased by such Title Benefit Amount.

(f) Section 3.4(d) shall be the exclusive right and remedy of Purchaser with respect to Seller's breach of its warranty and representation of Defensible Title in
Section 3.1(a).

(g) The Title Defect Amount resulting from a Title Defect shall be determined as follows:

(i) if Purchaser and Seller mutually agree upon the Title Defect Amount, that amount shall be the Title Defect Amount;

(ii) if the Title Defect is a lien, encumbrance or other charge which is undisputed and the amount of same can be exactly determined and agreed upon by Purchaser and Seller, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from the Title Defect Property;

(iii) if the Title Defect represents a discrepancy between (A) the Net Revenue Interest for any Title Defect Property (which has been agreed to by Seller and Purchaser) and (B) the Net Revenue Interest or percentage stated on Exhibit 1.2(b) and Exhibit 1.2(c), then the Title Defect Amount shall be the product of the Allocated Value of such Title Defect Property multiplied by a fraction, the numerator of which is the Net Revenue Interest for the Title Defect Property and the denominator of which is the Net Revenue Interest or percentage ownership stated on Exhibit 1.2(b) and Exhibit 1.2(c); and

(iv) if the Title Defect represents an obligation, encumbrance, burden or charge upon or other defect in title to the Title Defect Property of a type not described in subsections (i), (ii) or (iii) above, the Title Defect Amount shall be determined by taking into account the Allocated Value of the Title Defect Property, the portion of the Title Defect Property affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the Title Defect Property, the values placed upon the Title Defect by Purchaser and Seller and such other factors as are necessary to make a proper evaluation.

(h) The Title Benefit Amount for any Title Benefit shall be the product of the Allocated Value of the affected Unit or Well multiplied by a fraction, the numerator of which is the upwardly revised Net Revenue Interest and the denominator of which is the Net Revenue Interest stated on Exhibit 1.2(b) and Exhibit 1.2(c).

(i) Seller and Purchaser shall attempt to agree on all Title Defect Amounts and Title Benefit Amounts prior to Closing. If Seller and Purchaser are unable to agree by no later than two (2) Business Days prior to Closing, Seller, at Seller's sole election, may unilaterally terminate this Agreement, in which case Purchaser shall be entitled to an immediate refund of the Deposit from Seller, or the dispute may be submitted to arbitration as provided in Section 7.15.

(j) Notwithstanding anything to the contrary, there shall be no adjustments to the Purchase Price or other remedies provided by Seller for Title Defects unless
(i) each individual Title Defect exceeds $25,000.00 and
(ii) the aggregate amount of all uncured Title Defects exceeds a deductible in an amount equal to two percent (2%) of the Purchase Price, after which point Purchaser shall be entitled to adjustments to the Purchase Price or other remedies only with respect to Title Defects in excess of such deductible. Notwithstanding anything to the contrary, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Title Defect Property shall not exceed the Allocated Value of the Title Defect Property.

Section 3.5 Consents to Assignment and Preferential Rights to Purchase.

(a) Seller shall exercise reasonable efforts to obtain all such permissions, approvals and consents by governmental authorities and others which are reasonably obtainable by Closing and are required to vest Defensible Title to the Assets in Purchaser. Seller shall notify Purchaser at least five (5) Business Days prior to Closing of all required third- party consents to the assignment of the Assets to Purchaser which have not been obtained and the Assets to which they pertain. In no event shall there be included in the Assignment and Bill of Sale at Closing any Asset subject to a consent requirement that provides that transfer of the Asset without consent will result in a termination or other material impairment of any rights in relation to such Asset. In cases where the Asset subject to such a requirement is a Contract and Purchaser is assigned the Assets to which the Contract relates, but the Contract is not transferred to Purchaser due to the unwaived consent requirement, Seller shall continue after Closing to use reasonable efforts to obtain such consent so that such Contract can be transferred to Purchaser upon receipt of such consent. In cases where the Asset subject to such a requirement is a Property and the third-party consent to the sale and transfer of the Property is not obtained prior to the Closing Date, Purchaser may elect to treat the unsatisfied consent requirement as a Title Defect by giving Seller notice thereof in accordance with Section 3.4(a), except that such notice must be given at least two (2) Business Days prior to the Closing Date. In such event, the failure to obtain such consent to assignment shall be treated as if the affected Assets were subject to a Title Defect that resulted in the complete loss of title to such Assets, the affected Assets shall be excluded from the Assignment and Bill of Sale and the Purchase Price shall be reduced under Section 2.2(b) by the Allocated Value for such Assets. If a consent requirement with respect to which a Purchase Price adjustment is made under Section 3.4 is subsequently satisfied prior to the date of the final adjustment to the Purchase Price under Section 9.4(b), Purchaser shall pay to Seller the amount of the previous reduction in the Purchase Price and the affected Assets shall be assigned to Purchaser.

(b) If any preferential rights to purchase any Assets are exercised prior to Closing, those Assets transferred to a holder of preferential right to purchase as a result of the exercise of such preferential rights shall be treated as if those Assets were subject to a Title Defect that resulted in the complete loss of title to such Assets, and the Purchase Price shall be reduced under Section 2.2(b) by the Allocated Value for such Assets. Seller shall convey such Assets to the holder of preferential right to purchase exercising the preferential right to purchase, and Seller shall retain the consideration paid by the holder of preferential right to purchase for such Assets.

Section 3.6 Casualty Loss.

After the date this Agreement is executed but prior to the Closing Date, if any portion of the Assets is destroyed by fire or other casualty, this transaction shall nevertheless close. In the event that the loss resulting from the casualty is an amount less than five percent (5%) of the unadjusted Purchase Price, this transaction shall nevertheless close and Seller shall have no obligation regarding the casualty. In the event that the resulting loss is an amount equal to or greater than five percent (5%)of the unadjusted Purchase Price, Seller, at Seller's sole election, shall select one of the following options which shall apply to the casualty: (i) Seller shall cause the Assets affected by such casualty to be repaired or restored to at least its condition prior to such casualty, at Seller's sole cost, as promptly as reasonably practicable
(which work may extend after the Closing Date); or (ii)
Seller shall, at Closing, pay to Purchaser all sums paid to Seller by third parties by reason of such casualty and shall assign to Purchaser all of Seller's right, title and interest (if any) in insurance claims, unpaid awards, and other rights against third parties other than Seller Indemnitees arising out of the casualty; or (iii) Seller may treat such casualty as a Title Defect with respect to the affected Assets. In the event that Seller elects (i) or
(iii) above, Seller shall retain all rights to insurance and other claims against third parties with respect to the casualty.

Section 3.7 Condemnation Loss.

After the date this Agreement is executed but prior to the Closing Date, if any portion of the Assets is taken in condemnation or under right of eminent domain, this transaction shall nevertheless close. In such event, Seller, at Seller's sole election, shall select one of the following options which shall apply to the taking: (i) Seller shall, at Closing, pay to Purchaser all sums paid to Seller by third parties by reason of such taking and shall assign, transfer and set over to Purchaser all of Seller's right, title and interest (if any) in insurance claims, unpaid awards, and other rights against third parties other than Seller Indemnitees arising out of the taking; or (ii) Seller shall treat the taking as if the affected Assets were subject to a Title Defect that resulted in the complete loss of title to such Assets, and the Purchase Price shall be reduced under Section 2.2 by the Allocated Value for such Assets. In the case of (ii) above, Seller shall retain all rights to insurance and other claims against third parties with respect to the taking.

Section 3.8 Limitations on Applicability.

The Seller's representation and warranty of Defensible Title in Section 3.1(a) shall terminate as of the Title Claim Date and shall have no further force and effect thereafter. Thereafter, Purchaser's sole and exclusive remedies with regard to title to the Assets shall be the special warranty of title to the Leases contained in the Assignment and Bill of Sale.

ARTICLE 4
ENVIRONMENTAL MATTERS

Section 4.1 Environmental Assessment.

Purchaser may, at its option, inspect the Properties and cause an environmental assessment (the "Environmental Assessment") of all or any portion of the Properties to be conducted by a reputable environmental consulting or engineering firm approved in advance in writing by Seller. An Environmental Assessment shall be conducted at a time agreed to by Seller with a representative of Seller present. Purchaser shall provide Seller with a correct copy of any Environmental Assessment and all findings made in connection therewith. Except for such disclosure to Seller, Purchaser shall maintain the results of any Environmental Assessment and all findings made in connection therewith as strictly confidential. All information related an environmental assessment and all findings made in connection therewith shall be subject to the terms of the Confidentiality Agreement. Without the prior written consent of Seller, Purchaser shall not disclose the results of any Environmental Assessment and all findings made in connection therewith to any Person other than (i) the consultant that conducts the Environmental Assessment, (ii) Purchaser's lender (only in the events that (a) Purchaser's lender is lending money to Purchaser in connection with this Agreement and (b) provided Purchaser's lender first agrees in writing to keep such information confidential) and (iii) Seller. Any Environmental Assessment shall be conducted at the sole risk, cost and expense of Purchaser, and Purchaser shall Indemnify Seller from and against any and all losses arising from the Environmental Assessment as provided in Section 7.7 and Section 11.3(b).

Section 4.2 Notice of Material Adverse Environmental Condition.

Purchaser may notify Seller in writing on or before five (5) Business Days prior to Closing of any environmental matters disclosed by the Environmental Assessment that Purchaser reasonably believes in good faith may constitute a Material Adverse Environmental Condition. Such notice shall include a reasonably detailed description of all matters disclosed by the Environmental Assessment.

Section 4.3 Environmental Remedies.

If Purchaser delivers to Seller a notice pursuant to Section 4.2 that describes a Material Adverse Environmental Condition, then Seller shall, at its sole election, select one of the following options which shall apply to all Material Adverse Environmental Conditions:

(a) Seller shall reduce the Purchase Price by an amount agreed upon in writing by Purchaser and Seller as being a reasonable estimate of the cost of remediating or curing such Material Adverse Environmental Condition;

(b) Seller shall retain the Property that is subject to such Material Adverse Environmental Condition, in which event the affected Property shall be deleted from this Agreement and the Purchase Price shall be reduced by an amount equal to the Allocated Value of such affected Property;

(c) Seller shall perform or cause to be performed prior to Closing, at the sole expense of Seller, such operations as may be necessary to remediate or cure such Material Adverse Environmental Condition; or

(d) Seller shall enter into an agreement with Purchaser whereby Seller will as soon as reasonably practicable after Closing, at the sole cost and expense of Seller, perform or cause to be performed such operations as may be necessary to remediate or cure such Material Adverse Environmental Condition.

In the event that Seller elects to proceed under Section 4.3(a) and Purchaser and Seller have failed to agree on the amount by which the Purchase Price shall be reduced (which agreement Seller and Purchaser shall use good faith efforts to reach) by Closing, then, in such event, the dispute shall be submitted to arbitration as provided in Section 7.15.

Notwithstanding the foregoing, in the events that (i) Purchaser conducts an Environmental Assessment on the Properties which discloses environmental matters that Purchaser reasonably believes in good faith may constitute a Material Adverse Environmental Condition; (ii) Purchaser delivers a notice to Seller as required in Section 4.2;
(iii) the cost of remediating the Material Adverse Environmental Condition that is described in Purchaser's notice pursuant to Section 4.2 and/or the Environmental Liabilities attributable to the Material Adverse Environmental Condition that is described in Purchaser's notice pursuant to Section 4.2 exceed three percent (3%) of the unadjusted Purchase Price; and (iv) Purchaser delivers to Seller written notice of termination of this Agreement at least five (5) Business Days prior to Closing Date, then, in the event of the completion and satisfaction of each of the four conditions listed above, Purchaser, at Purchaser's sole election, may unilaterally terminate this Agreement without liability to Seller. If Purchaser terminates this Agreement pursuant to this section, Purchaser shall be entitled to a prompt refund of the full amount of the Deposit from Seller.

Section 4.4 Limitations.

(a) This Article 4 is intended to be the sole and exclusive remedy that Purchaser Indemnitees shall have against Seller Indemnitees with respect to any matter or circumstance relating to Material Adverse Environmental Conditions, Environmental Liabilities, Environmental Laws, the release of materials into the environment, the protection of the environment or health or any matters that Purchaser could have included in a notice delivered pursuant to Section 4.2.

(b) Purchaser, on behalf of itself and each of the other Purchaser Indemnitees, hereby fully releases and discharges the Seller Indemnitees from any and all claims at Law or in equity, known or unknown, whether occurring before the Effective Time, existing at the Effective Time or arising after the Effective Time, contingent or otherwise, with respect to all matters relating to Material Adverse Environmental Conditions, Environmental Liabilities, Environmental Laws, the release of materials into the environment, the protection of the environment or health or any matters that Purchaser could have included in a notice delivered pursuant to Section 4.2 EVEN IF SUCH DAMAGES OR CLAIMS ARE CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT) OF SELLER INDEMNITEES OR THE STRICT LIABILITY OF SELLER INDEMNITEES.

(c) Purchaser acknowledges that Seller has not made and will not make any representation or warranty regarding any matter or circumstance relating to Material Adverse Environmental Conditions, Environmental Laws, the release of materials into the environment or protection of the environment or health, and that nothing in Article 5 or otherwise shall be construed as such a representation or warranty.

Should Purchaser (i) determine that the gas imbalance information set out on Exhibit 5.13 is inaccurate and (ii) deliver a written notice regarding the gas imbalance to Seller at least five (5) Business Days prior to Closing, Seller shall review Purchaser's information regarding the alleged gas imbalance.

(b) Seller shall promptly prepare and send notices to the holders of any applicable preferential rights to purchase any Asset requesting waivers of such preferential rights to purchase. The consideration payable under this Agreement for any particular Assets for purposes of preferential purchase right notices shall be the Allocated Value for such Assets. Seller shall use reasonable efforts to cause such waivers of preferential rights to purchase (or the exercise thereof) to be obtained and delivered prior to Closing. Purchaser shall cooperate with Seller in seeking to obtain such waivers of preferential rights.

If the holder of a preferential right to purchase exercises such right, Seller shall tender to such third party the required interest in the affected Asset at a price equal to the Allocated Value (reduced appropriately, as determined by mutual agreement of Purchaser and Seller, if less than the entire Asset must be tendered), and to the extent that such preferential right to purchase is exercised and such interest in such Asset is actually sold to the third party so exercising such right, the Assets transferred will be treated as if subject to a Title Defect and the procedures set forth in Section 3.5(b) shall apply.

Should a holder of a preferential right to purchase fail to exercise its preferential right to purchase as to any portion of the Assets prior to Closing and the time for exercise or waiver has not yet expired prior to Closing, subject to the remaining provisions of this
Section 7.9, such Assets shall be included in the transaction contemplated by this Agreement at Closing and the following procedures shall be applicable:

(i) An Assignment and Bill of Sale from Seller to Purchaser of the Assets affected by such preferential right to purchase shall be delivered into an escrow account, Purchaser shall take beneficial possession of the affected Assets and Purchaser shall be entitled to all production, income, proceeds, receipts and credits to which Purchaser would be entitled under Section
11.1. Purchaser shall Indemnify Seller Indemnitees against Damages for which Purchaser would be liable under the terms of Sections 11.2 and 11.3 with respect to the affected Assets. Record title to the affected Assets shall not be transferred and the Assignment and Bill of Sale shall not be released to Purchaser from the escrow account until such preferential right to purchase has been waived or has expired. PURCHASER'S INDEMNIFICATION OF SELLER INDEMNITEES SHALL BE PURSUANT TO AND IN ACCORDANCE WITH THE INDEMNIFICATION PROVISIONS SET OUT IN SECTION 11.3(b) AND SHALL INCLUDE, WITHOUT LIMITATION, INDEMNIFICATION AGAINST DAMAGES AND LITIGATION EXPENSES.

(ii) Seller shall continue to use reasonable efforts to obtain the waiver of the preferential right to purchase and shall continue to be responsible for the compliance with the preferential right to purchase.

(iii) Should the holder of the preferential right to purchase exercise same, Purchaser and Seller agree to cause the affected Assets to be transferred to such holder on the terms and provisions set out herein and in the applicable preferential right to purchase provision. In such event, Seller shall pay the Allocated Value, subject to applicable adjustments, for such Asset to Purchaser, and Seller shall be entitled to retain the consideration paid for the affected Asset by the holder of the preferential right to purchase.

(iv) If the preferential right to purchase is waived after the Closing Date or if the time limit for the exercise of the preferential right to purchase expires without being exercised, Seller and Purchaser shall take all reasonable actions necessary to ensure that the affected Assets are promptly conveyed out of escrow to Purchaser.

(v) Once the provisions of subparagraph (iv) have been satisfied and all obligations in connection therewith have been fulfilled, the Closing shall be deemed to have occurred for all purposes hereunder with respect to the affected Assets.

Should any third party bring any suit, action or other proceeding seeking to restrain, enjoin or otherwise prohibit the consummation of the transactions contemplated hereby in connection with a claim to enforce preferential rights, the Assets affected by such suit, action or other proceeding shall be excluded from the Assets transferred at Closing and the Purchase Price shall be reduced by the Allocated Value of such excluded Assets. Promptly after the suit, action or other proceeding is dismissed or settled or a judgment is rendered, Seller shall sell to Purchaser and Purchaser shall purchase from Seller all such Assets not being sold to the third party for a purchase price equal to the Allocated Value of such Assets, adjusted as provided in Section 2.2.

(b) To make a claim for indemnification under Section 11.3, an Indemnified Party shall provide to the Indemnifying Party a written notice (the "Indemnification Notice") which specifies the basis of the Indemnified Party's entitlement to indemnification under this Agreement. In the event that the Indemnification Notice is based upon a claim by a third party against the Indemnified Party (a "Third Party Claim"), the Indemnified Party shall provide its Indemnification Notice promptly after the Indemnified Party has actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim; provided that the failure of any Indemnified Party to give notice of a Third Party Claim as provided in this Section 11.4 shall not relieve the Indemnifying Party of its obligations under Section 11.3 except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise prejudices the Indemnifying Party's ability to defend against the Third Party Claim.

(c) The Indemnifying Party shall have thirty (30) days from its receipt of an Indemnification Notice to notify the Indemnified Party whether it will assume the defense of the Indemnified Party against such Third Party Claim at the sole cost and expense of the Indemnifying Party.

(d) If the Indemnifying Party assumes the defense of a Third Party Claim pursuant to an Indemnification Notice, the Indemnifying Party shall diligently defend, at its sole cost and expense, the Indemnified Party against the Third Party Claim. The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate in contesting any Third Party Claim which the Indemnifying Party elects to contest. The Indemnified Party may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 11.4(d). An Indemnifying Party shall not, without the written consent of the Indemnified Party, (i) settle any Third Party Claim or consent to the entry of any judgment with respect thereto which does not include an unconditional written release of the Indemnified Party from all liability in respect of such Third Party Claim or (ii) settle any Third Party Claim or consent to the entry of any judgment with respect thereto in any manner that may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity).

(e) If the Indemnifying Party does not assume the defense of the Indemnified Party against a Third Party Claim or assumes the defense, but fails to diligently prosecute or settle the Third Party Claim, then the Indemnified Party shall have the right to defend against the Third Party Claim at the sole cost and expense of the Indemnifying Party, with counsel of the Indemnified Party's choice, subject to the right of the Indemnifying Party to assume the defense of the Third Party Claim at any time prior to settlement or final determination thereof. If the Indemnifying Party has not yet assumed the defense of the Indemnified Party, the Indemnified Party shall send written notice to the Indemnifying Party of any proposed settlement or final determination of the Third Party Claim and the Indemnifying Party shall have the option for ten (10) days following receipt of such notice to (i) assume defense against the Third Party Claim in writing and
(ii) if so assumed, reject, in its reasonable judgment, the proposed settlement or final determination of the Third Party Claim.

(f) In the event that the Indemnification Notice sets forth a claim for Damages based upon an inaccuracy or breach of a representation, warranty or covenant or obligation in this Agreement, the Indemnification Notice shall specify the representation, warranty, covenant or obligation which was inaccurate or breached. In such case, the Indemnifying Party shall have thirty (30) days from its receipt of the Indemnification Notice to (i) cure the Damages complained of, (ii) accept the claim for such Damages or (iii) dispute the claim for such Damages. If the Indemnifying Party does not notify the Indemnified Party within such thirty (30) day period that it has cured the Damages or that it disputes the claim for such Damages, the amount of such Damages shall conclusively be deemed a liability of the Indemnifying Party hereunder.

(a) Purchaser shall be entitled to all (i) Hydrocarbons produced from or attributable to the Properties at and after the Effective Time, (ii) proceeds from the sale of Hydrocarbons at and after the Effective Time and
(iii) other income, proceeds, receipts and credits earned with respect to the Assets at or after the Effective Time. Purchaser shall be liable and responsible for (and entitled to any refunds with respect to) all Property Costs incurred at and after the Effective Time.

(b) Seller shall be entitled to all (i) Hydrocarbons produced from or attributable to the Properties prior to the Effective Time, (ii) proceeds from the sale of Hydrocarbons prior to the Effective Time and (iii) other income, proceeds, receipts and credits earned with respect to the Assets prior to the Effective Time.

(c) Right-of-way fees, insurance premiums and other Property Costs that are paid periodically and cannot be accurately identified as being incurred when paid shall be prorated based on the number of days in the applicable period falling before and the number of days in the applicable period falling at or after the Effective Time.

(d) Ad valorem, production, severance and similar Taxes shall be prorated based on the number of units actually produced, purchased or sold or proceeds of sale, as applicable, before, and at or after, the Effective Time. In each case, Purchaser shall be responsible for the portion allocated to the period at and after the Effective Time, and Seller shall be responsible for the portion allocated to the period before the Effective Time.

Seller shall utilize reasonable interpolative procedures to arrive at an allocation of production when exact meter readings or gauging and strapping data is not available. Seller shall provide to Purchaser, no later than four (4) Business Days prior to Closing, all data necessary to support any estimated allocation, for purposes of establishing the adjustment to the Purchase Price pursuant to Section 2.2 hereof that will be used to determine the Closing Payment.

ARTICLE 2
PURCHASE PRICE

Section 2.1 Purchase Price.

The purchase price for the Assets (the "Purchase Price") shall be Seventy Four Million Nine Hundred Twenty Eight Thousand Two Hundred Thirty Six Dollars (U.S. $74,928,236.00) adjusted as provided in Section 2.2.

Section 2.2 Adjustments to Purchase Price.

The Purchase Price for the Assets shall be adjusted as follows:

(a) Reduced by the aggregate amount of the proceeds received by Seller from the sale of Hydrocarbons and other proceeds earned and attributable to the Assets during the Adjustment Period;

(b) Reduced in accordance with Section 3.5, by an amount equal to the Allocated Value of those Properties (i) with respect to which preferential purchase rights have been exercised prior to Closing or (ii) that cannot be transferred at Closing because consents to the assignments of those Properties have not been obtained;

(c) Reduced by the aggregate amounts payable to owners of working interests, royalties and overriding royalties and other interests in the Properties held in suspense by Seller as of the Closing Date unless the suspended funds are transferred by Seller to Purchaser on the Closing Date;

(d) Reduced by Seller's pro-rata share of ad valorem taxes;

(e) Reduced in accordance with Article 3 by amounts as remedies for Title Defects;

(f) Reduced in accordance with Article 4 pursuant to
Section 4.3 regarding environmental matters;

(g) Increased by the amount of all Property Costs which have been paid by Seller and incurred during the Adjustment Period, except for any Property Costs and other such costs already deducted in the determination of proceeds in Section 2.2(a);

(h) Increased or decreased, as appropriate, pursuant to the provisions of Section 7.8 dealing with gas imbalances and/or take-or-pay make-up obligations; and

(i) Increased by the amount of any Title Benefit pursuant to Section 3.4(e).

(j) Increased or decreased by other amounts mutually agreed to by Seller and Purchaser.

All such adjustments shall be determined in accordance with generally accepted accounting principles and Council of Petroleum Accountants Society (COPAS) standards.

The adjustment described in Section 2.2(a) shall serve to satisfy, up to the amount of the adjustment, Purchaser's entitlement under Section 1.6 to Hydrocarbon production from or attributable to the Properties during the Adjustment Period, and to the other income, proceeds, receipts and credits earned with respect to the Assets during the Adjustment Period. Purchaser shall not have any separate rights to receive any production or income, proceeds, receipts and credits with respect to which an adjustment has been made. Similarly, the adjustment described in Section 2.2(g) shall serve to satisfy, up to the amount of the adjustment, Purchaser's obligation under Section 1.6 to pay Property Costs and other costs attributable to the ownership and operation of the Assets which are incurred during the Adjustment Period. Purchaser shall not be separately obligated to pay for any Property Costs or other such costs with respect to which an adjustment has been made.

Section 2.3 Allocation of Purchase Price.

(a) Simultaneous with the execution of this Agreement, Purchaser will deliver to Seller a draft allocation of the unadjusted Purchase Price among each of the Assets, which has been made in compliance with the principles of Section 1060 of the Internal Revenue Code of 1986, as amended (the "Code"), and the Treasury regulations thereunder. Within two (2) Business Days after Seller has received Purchaser's draft allocation, Seller and Purchaser will attempt to agree on the final allocation of the unadjusted Purchase Price among each of the Assets; provided, however, that in no event shall any such allocation of value be deemed final until Seller and Purchaser have approved the same in writing. Once approved by all parties, such allocation of value shall be attached to this Agreement as Exhibit 2.3. The "Allocated Value" for any Asset shall equal the portion of the unadjusted Purchase Price allocated to such Asset on Exhibit 2.3, increased or decreased by its respective proportionate share of the price adjustments described in Section
2.2. After Seller and Purchaser have agreed on the Allocated Values for the Assets, Seller and Purchaser will be deemed to have accepted such Allocated Values for purposes of this Agreement and the transactions contemplated hereby. Seller, however, makes no representation or warranty to Purchaser as to the accuracy of such values. Seller and Purchaser agree (i) that the Allocated Values shall be used by Seller and Purchaser as the basis for notices to holders of preferential rights to purchase and (ii) that neither Seller nor Purchaser will take positions inconsistent with the Allocated Values in notices to government authorities, in audit or other proceedings with respect to Taxes, in notices to holders of preferential rights to purchase. Purchaser and Seller further agree that, on or before the Closing Date, they will mutually agree as to the further allocation of the Allocated Values included in Exhibit 2.3 as to the relative portion of those values attributable to leasehold costs and depreciable Equipment.

(b) In the event that Seller and Purchaser are unable to agree as to the Allocated Values, at the sole election of Seller, (i) this Agreement may be terminated unilaterally by Seller, in which case Purchaser shall be entitled to an immediate refund of the Deposit from Seller, or (ii) the dispute may be submitted to arbitration as provided in Section 7.15 below.

Section 2.4 Deposit.

Concurrently with the execution of this Agreement, Purchaser shall wire transfer to Seller an earnest money deposit in an amount equal to five percent (5 %) of the Purchase Price (the "Deposit"). The Deposit shall be applied against the Purchase Price if the Closing occurs or shall be otherwise distributed in accordance with the terms of this Agreement.

ARTICLE 3
TITLE MATTERS

Section 3.1 Seller's Title.

(a) Seller represents and warrants to Purchaser that Seller's title to the Wells shown on Exhibit 1.2(b) and the Units shown on Exhibit 1.2(c) as of the Effective Time is (and as of the Closing Date shall be) Defensible Title.

(b) The Assignment and Bill of Sale to be delivered by Seller to Purchaser shall be in form identical to the assignment shown on Exhibit 3.1(b) attached hereto and shall contain a special warranty of title by, through and under Seller, but not otherwise, to the Leases shown on Exhibit 1.2(a), subject to the Permitted Encumbrances. Otherwise, the Assignment and Bill of Sale shall be without warranty of title, express, implied, statutory or otherwise. The Assignment and Bill of Sale shall transfer to Purchaser all rights or actions on title warranties given or made by Seller's predecessors (other than Affiliates of Seller), to the extent Seller may legally transfer such rights.

(c) Purchaser shall not be entitled to protection under Seller's special warranty of title in the Assignment and Bill of Sale against any Title Defect reported by Purchaser to Seller under this Article 3. All reported Title Defects shall be covered by the provisions of Article 3 and are expressly excluded from protection under Seller's special warranty of title in the Assignment and Bill of Sale.

Section 3.2 Defensible Title.

As used in this Agreement, the term "Defensible Title" means that title of Seller which, subject to Permitted Encumbrances:

(a) Entitles Seller to receive a share of the Hydrocarbons produced, saved and marketed from any Unit or Well throughout the duration of the productive life of such Unit or Well after satisfaction of all royalties, overriding royalties, nonparticipating royalties, net profits interests or other similar burdens on or measured by production of Hydrocarbons (a "Net Revenue Interest") of not less than the Net Revenue Interest share shown in Exhibit 1.2(b) for the Wells and Exhibit 1.2(c) for the Units, except decreases in connection with those operations in which Seller may after the Effective Time be a non-consenting co-owner, decreases resulting from the establishment or amendment after the Effective Time of units, and decreases required to allow other working interest owners to make up past underproduction or pipelines to make up past under deliveries;

(b) Obligates Seller to bear a percentage of the Property Costs relating to any Unit or Well not greater than the "Working Interest" shown in Exhibit 1.2(b) for Wells and Exhibit 1.2(c) for Units without increase throughout the productive life of such Wells or Units except increases resulting from contribution requirements with respect to defaulting co-owners under applicable operating agreements and increases that are accompanied by at least a proportionate increase in Seller's Net Revenue Interest; and

(c) Is free and clear of liens, encumbrances, obligations, security interests, pledges or other defects.

The term "Title Defect" shall mean any liens, encumbrances, obligations, security interests, pledges or other defects, including, without limitation, discrepancies in Net Revenue Interest or Working Interest, that cause a breach of Seller's representation and warranty of Defensible Title in
Section 3.1(a).

The term "Title Benefit" shall mean any right, circumstance or condition that operates to increase the Net Revenue Interest of Seller in any Property above that shown on Exhibit 1.2(b) and Exhibit 1.2(c), without causing a greater than proportionate increase in Seller's Working Interest above that shown in Exhibit 1.2(b) and Exhibit 1.2(c).

Section 3.3 Permitted Encumbrances.

As used herein, the term "Permitted Encumbrances" shall mean any or all of the following:

(a) Royalties and any overriding royalties, reversionary interests and other burdens to the extent that they do not, individually or in the aggregate, reduce Seller's Net Revenue Interest below that shown in Exhibit 1.2(b) and Exhibit 1.2(c) or increase Seller's Working Interest above that shown in Exhibit 1.2(b) and Exhibit 1.2(c) without a corresponding increase in the Net Revenue Interest;

(b) All Leases, unit agreements, pooling agreements, operating agreements, production sales contracts, division orders and other Contracts applicable to the Assets, to the extent that they do not, individually or in the aggregate, reduce Seller's Net Revenue Interest below that shown in Exhibit 1.2(b) and Exhibit 1.2(c) or increase Seller's Working Interest above that shown in Exhibit 1.2(b) and Exhibit 1.2(c) without a corresponding increase in the Net Revenue Interest;

(c) Preferential rights to purchase the Assets with respect to which, prior to Closing, (i) waivers are obtained from the holders of such preferential rights to purchase and/or (ii) the appropriate time period for asserting such rights has expired without an exercise of such rights;

(d) Third-party consent to assignment requirements and similar restrictions with respect to which waivers or consents are obtained by Seller from the appropriate parties prior to the Closing Date or the appropriate time period for asserting the right has expired or which need not be satisfied prior to a transfer;

(e) Liens for current Taxes or assessments not yet delinquent or, if delinquent, being contested in good faith by appropriate actions;

(f) Liens or charges arising in the ordinary course of business for amounts not yet delinquent (including any amounts being withheld as provided by law), or if delinquent, being contested in good faith by appropriate actions;

(g) All rights to consent, by required notices to, filings with, or other actions by Governmental Bodies in connection with the sale or conveyance of oil and gas leases or interests therein if they are not required prior to the sale or conveyance;

(h) Rights of reassignment arising upon final intention to abandon or release the Assets, or any of them;

(i) Easements, rights-of-way, servitudes, permits, surface leases and other rights in respect of surface operations to the extent that they do not, individually or in the aggregate, reduce Seller's Net Revenue Interest below that shown in Exhibits 1.2(b) and Exhibit 1.2(c) or increase Seller's Working Interest above that shown in Exhibits 1.2(b) and Exhibit 1.2(c) without a corresponding increase in Net Revenue Interest;

(j) Calls on production under existing Contracts;

(k) All rights reserved to or vested in any Governmental Body to control or regulate any of the Assets in any manner and all obligations and duties under all applicable laws, rules and orders of any such Governmental Body or under any franchise, grant, license or permit issued by any such Governmental Body;

(l) Any encumbrance affecting the Assets which is discharged by Seller prior to or at Closing or which is expressly assumed, bonded or paid by Purchaser prior to or at Closing;

(m) Any matters shown on Exhibit 1.2(a), Exhibit 1.2(b) and Exhibit 1.2(c); and

(n) Any other liens, charges, encumbrances, defects or irregularities which do not, individually or in the aggregate, materially detract from the value of or materially interfere with the use or ownership of the Assets subject thereto or affected thereby (as currently used or owned), which would be accepted by a reasonably prudent Purchaser engaged in the business of owning and operating oil and gas Assets, and which do not reduce Seller's Net Revenue Interest below that shown in Exhibit 1.2(b) and Exhibit 1.2(c), or increase Seller's Working Interest above that shown in Exhibit 1.2(b) and Exhibit 1.2(c) without a corresponding increase in Net Revenue Interest.

Section 3.4 Notice of Title Defects.

(a) To assert a claim arising out of a breach of Seller's representation and warranty of Defensible Title in Section 3.1(a), Purchaser must deliver claim notices to Seller (each a "Title Defect Notice") on or before ten (10) Business Days prior to the Closing Date (the "Title Claim Date"), except as otherwise provided in Sections 3.5, 3.6 or 3.7. Each Title Defect Notice shall be in writing and shall include (i) a description of the alleged Title Defect(s), (ii) the Leases, Units or Wells affected by the Title Defect (each a "Title Defect Property"), (iii) the Allocated Values of each Title Defect Property, (iv) supporting documents reasonably necessary for Seller (as well as any title attorney or examiner hired by Seller) to verify the existence of the alleged Title Defect(s) and (v) the amount by which Purchaser reasonably believes the Allocated Values of each Title Defect Property are reduced by the alleged Title Defect(s) and the computations and information upon which Purchaser's belief is based. Purchaser shall be deemed to have waived all breaches of Seller's representation and warranty of Defensible Title in Section 3.1(a) of which Seller has not been given notice on or before the Title Claim Date.

(b) Seller shall have the right, but not the obligation, to deliver to Purchaser on or before the Title Claim Date with respect to each Title Benefit a notice (a "Title Benefit Notice") including (i) a description of the Title Benefit, (ii) the Leases, Units or Wells affected, (iii) the Allocated Values of the Units or Wells subject to such Title Benefit and
(iv) the amount by which the Seller reasonably believes the Allocated Value of those Units or Wells is increased by the Title Benefit, and the computations and information upon which Seller's belief is based. Seller shall be deemed to have waived all Title Benefits of which it has not given notice on or before the Title Claim Date.

(c) In the event that Seller receives a Title Defect Notice, Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure or remove any Title Defects of which it has been advised by Purchaser in the Title Defect Notice prior to Closing.

(d) Remedies for Title Defects.

In the event that any Title Defect is not waived by Purchaser or cured on or before Closing, Seller shall, at its sole election, select one of the following options which shall apply regarding uncured Title Defects:

(i) The Purchase Price shall be reduced by an amount agreed upon ("Title Defect Amount") pursuant to Section 3.4(g) or 3.4(i) by Purchaser and Seller as being the value of such Title Defect, taking into consideration the Allocated Value of the Property subject to such Title Defect, the portion of the Property subject to such Title Defect and the legal effect of such Title Defect on the Property affected thereby;

(ii) Purchaser and Seller shall enter into a separate written agreement whereby Seller will as soon as reasonably practicable after Closing, at the sole cost and expense of Seller, cure or remove such Title Defects to Purchaser's reasonable satisfaction; or

(iii) Seller shall retain the affected Property, in which event the affected Property shall be deleted from this Agreement and the Purchase Price shall be reduced by an amount equal to the Allocated Value of such affected Property.

In the event that Seller elects to proceed under
Section 3.4(d)(i) and, after a reasonable time for good faith negotiation, Purchaser and Seller have failed to agree on the amount by which the Purchase Price should be reduced by Closing, then in such event, Seller, at Seller's sole election, may select one of the other options in 3.4(d), unilaterally terminate this Agreement, in which case Purchaser shall be entitled to an immediate refund of the Deposit from Seller, or the dispute may be submitted to arbitration as provided in
Section 7.15.

(e) With respect to each Unit or Well affected by Title Benefits reported under Section 3.4(b), the Purchase Price shall be increased by an amount (the "Title Benefit Amount") equal to the increase in the Allocated Value for such Unit or Well caused by such Title Benefits, as determined pursuant to Section 3.4(h). The Closing Payment shall be increased by such Title Benefit Amount.

(f) Section 3.4(d) shall be the exclusive right and remedy of Purchaser with respect to Seller's breach of its warranty and representation of Defensible Title in
Section 3.1(a).

(g) The Title Defect Amount resulting from a Title Defect shall be determined as follows:

(i) if Purchaser and Seller mutually agree upon the Title Defect Amount, that amount shall be the Title Defect Amount;

(ii) if the Title Defect is a lien, encumbrance or other charge which is undisputed and the amount of same can be exactly determined and agreed upon by Purchaser and Seller, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from the Title Defect Property;

(iii) if the Title Defect represents a discrepancy between (A) the Net Revenue Interest for any Title Defect Property (which has been agreed to by Seller and Purchaser) and (B) the Net Revenue Interest or percentage stated on Exhibit 1.2(b) and Exhibit 1.2(c), then the Title Defect Amount shall be the product of the Allocated Value of such Title Defect Property multiplied by a fraction, the numerator of which is the Net Revenue Interest for the Title Defect Property and the denominator of which is the Net Revenue Interest or percentage ownership stated on Exhibit 1.2(b) and Exhibit 1.2(c); and

(iv) if the Title Defect represents an obligation, encumbrance, burden or charge upon or other defect in title to the Title Defect Property of a type not described in subsections (i), (ii) or (iii) above, the Title Defect Amount shall be determined by taking into account the Allocated Value of the Title Defect Property, the portion of the Title Defect Property affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the Title Defect Property, the values placed upon the Title Defect by Purchaser and Seller and such other factors as are necessary to make a proper evaluation.

(h) The Title Benefit Amount for any Title Benefit shall be the product of the Allocated Value of the affected Unit or Well multiplied by a fraction, the numerator of which is the upwardly revised Net Revenue Interest and the denominator of which is the Net Revenue Interest stated on Exhibit 1.2(b) and Exhibit 1.2(c).

(i) Seller and Purchaser shall attempt to agree on all Title Defect Amounts and Title Benefit Amounts prior to Closing. If Seller and Purchaser are unable to agree by no later than two (2) Business Days prior to Closing, Seller, at Seller's sole election, may unilaterally terminate this Agreement, in which case Purchaser shall be entitled to an immediate refund of the Deposit from Seller, or the dispute may be submitted to arbitration as provided in Section 7.15.

(j) Notwithstanding anything to the contrary, there shall be no adjustments to the Purchase Price or other remedies provided by Seller for Title Defects unless
(i) each individual Title Defect exceeds $25,000.00 and
(ii) the aggregate amount of all uncured Title Defects exceeds a deductible in an amount equal to two percent (2%) of the Purchase Price, after which point Purchaser shall be entitled to adjustments to the Purchase Price or other remedies only with respect to Title Defects in excess of such deductible. Notwithstanding anything to the contrary, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Title Defect Property shall not exceed the Allocated Value of the Title Defect Property.

Section 3.5 Consents to Assignment and Preferential Rights to Purchase.

(a) Seller shall exercise reasonable efforts to obtain all such permissions, approvals and consents by governmental authorities and others which are reasonably obtainable by Closing and are required to vest Defensible Title to the Assets in Purchaser. Seller shall notify Purchaser at least five (5) Business Days prior to Closing of all required third- party consents to the assignment of the Assets to Purchaser which have not been obtained and the Assets to which they pertain. In no event shall there be included in the Assignment and Bill of Sale at Closing any Asset subject to a consent requirement that provides that transfer of the Asset without consent will result in a termination or other material impairment of any rights in relation to such Asset. In cases where the Asset subject to such a requirement is a Contract and Purchaser is assigned the Assets to which the Contract relates, but the Contract is not transferred to Purchaser due to the unwaived consent requirement, Seller shall continue after Closing to use reasonable efforts to obtain such consent so that such Contract can be transferred to Purchaser upon receipt of such consent. In cases where the Asset subject to such a requirement is a Property and the third-party consent to the sale and transfer of the Property is not obtained prior to the Closing Date, Purchaser may elect to treat the unsatisfied consent requirement as a Title Defect by giving Seller notice thereof in accordance with Section 3.4(a), except that such notice must be given at least two (2) Business Days prior to the Closing Date. In such event, the failure to obtain such consent to assignment shall be treated as if the affected Assets were subject to a Title Defect that resulted in the complete loss of title to such Assets, the affected Assets shall be excluded from the Assignment and Bill of Sale and the Purchase Price shall be reduced under Section 2.2(b) by the Allocated Value for such Assets. If a consent requirement with respect to which a Purchase Price adjustment is made under Section 3.4 is subsequently satisfied prior to the date of the final adjustment to the Purchase Price under Section 9.4(b), Purchaser shall pay to Seller the amount of the previous reduction in the Purchase Price and the affected Assets shall be assigned to Purchaser.

(b) If any preferential rights to purchase any Assets are exercised prior to Closing, those Assets transferred to a holder of preferential right to purchase as a result of the exercise of such preferential rights shall be treated as if those Assets were subject to a Title Defect that resulted in the complete loss of title to such Assets, and the Purchase Price shall be reduced under Section 2.2(b) by the Allocated Value for such Assets. Seller shall convey such Assets to the holder of preferential right to purchase exercising the preferential right to purchase, and Seller shall retain the consideration paid by the holder of preferential right to purchase for such Assets.

Section 3.6 Casualty Loss.

After the date this Agreement is executed but prior to the Closing Date, if any portion of the Assets is destroyed by fire or other casualty, this transaction shall nevertheless close. In the event that the loss resulting from the casualty is an amount less than five percent (5%) of the unadjusted Purchase Price, this transaction shall nevertheless close and Seller shall have no obligation regarding the casualty. In the event that the resulting loss is an amount equal to or greater than five percent (5%)of the unadjusted Purchase Price, Seller, at Seller's sole election, shall select one of the following options which shall apply to the casualty: (i) Seller shall cause the Assets affected by such casualty to be repaired or restored to at least its condition prior to such casualty, at Seller's sole cost, as promptly as reasonably practicable
(which work may extend after the Closing Date); or (ii)
Seller shall, at Closing, pay to Purchaser all sums paid to Seller by third parties by reason of such casualty and shall assign to Purchaser all of Seller's right, title and interest (if any) in insurance claims, unpaid awards, and other rights against third parties other than Seller Indemnitees arising out of the casualty; or (iii) Seller may treat such casualty as a Title Defect with respect to the affected Assets. In the event that Seller elects (i) or
(iii) above, Seller shall retain all rights to insurance and other claims against third parties with respect to the casualty.

Section 3.7 Condemnation Loss.

After the date this Agreement is executed but prior to the Closing Date, if any portion of the Assets is taken in condemnation or under right of eminent domain, this transaction shall nevertheless close. In such event, Seller, at Seller's sole election, shall select one of the following options which shall apply to the taking: (i) Seller shall, at Closing, pay to Purchaser all sums paid to Seller by third parties by reason of such taking and shall assign, transfer and set over to Purchaser all of Seller's right, title and interest (if any) in insurance claims, unpaid awards, and other rights against third parties other than Seller Indemnitees arising out of the taking; or (ii) Seller shall treat the taking as if the affected Assets were subject to a Title Defect that resulted in the complete loss of title to such Assets, and the Purchase Price shall be reduced under Section 2.2 by the Allocated Value for such Assets. In the case of (ii) above, Seller shall retain all rights to insurance and other claims against third parties with respect to the taking.

Section 3.8 Limitations on Applicability.

The Seller's representation and warranty of Defensible Title in Section 3.1(a) shall terminate as of the Title Claim Date and shall have no further force and effect thereafter. Thereafter, Purchaser's sole and exclusive remedies with regard to title to the Assets shall be the special warranty of title to the Leases contained in the Assignment and Bill of Sale.

ARTICLE 4
ENVIRONMENTAL MATTERS

Section 4.1 Environmental Assessment.

Purchaser may, at its option, inspect the Properties and cause an environmental assessment (the "Environmental Assessment") of all or any portion of the Properties to be conducted by a reputable environmental consulting or engineering firm approved in advance in writing by Seller. An Environmental Assessment shall be conducted at a time agreed to by Seller with a representative of Seller present. Purchaser shall provide Seller with a correct copy of any Environmental Assessment and all findings made in connection therewith. Except for such disclosure to Seller, Purchaser shall maintain the results of any Environmental Assessment and all findings made in connection therewith as strictly confidential. All information related an environmental assessment and all findings made in connection therewith shall be subject to the terms of the Confidentiality Agreement. Without the prior written consent of Seller, Purchaser shall not disclose the results of any Environmental Assessment and all findings made in connection therewith to any Person other than (i) the consultant that conducts the Environmental Assessment, (ii) Purchaser's lender (only in the events that (a) Purchaser's lender is lending money to Purchaser in connection with this Agreement and (b) provided Purchaser's lender first agrees in writing to keep such information confidential) and (iii) Seller. Any Environmental Assessment shall be conducted at the sole risk, cost and expense of Purchaser, and Purchaser shall Indemnify Seller from and against any and all losses arising from the Environmental Assessment as provided in Section 7.7 and Section 11.3(b).

Section 4.2 Notice of Material Adverse Environmental Condition.

Purchaser may notify Seller in writing on or before five (5) Business Days prior to Closing of any environmental matters disclosed by the Environmental Assessment that Purchaser reasonably believes in good faith may constitute a Material Adverse Environmental Condition. Such notice shall include a reasonably detailed description of all matters disclosed by the Environmental Assessment.

Section 4.3 Environmental Remedies.

If Purchaser delivers to Seller a notice pursuant to Section 4.2 that describes a Material Adverse Environmental Condition, then Seller shall, at its sole election, select one of the following options which shall apply to all Material Adverse Environmental Conditions:

(a) Seller shall reduce the Purchase Price by an amount agreed upon in writing by Purchaser and Seller as being a reasonable estimate of the cost of remediating or curing such Material Adverse Environmental Condition;

(b) Seller shall retain the Property that is subject to such Material Adverse Environmental Condition, in which event the affected Property shall be deleted from this Agreement and the Purchase Price shall be reduced by an amount equal to the Allocated Value of such affected Property;

(c) Seller shall perform or cause to be performed prior to Closing, at the sole expense of Seller, such operations as may be necessary to remediate or cure such Material Adverse Environmental Condition; or

(d) Seller shall enter into an agreement with Purchaser whereby Seller will as soon as reasonably practicable after Closing, at the sole cost and expense of Seller, perform or cause to be performed such operations as may be necessary to remediate or cure such Material Adverse Environmental Condition.

In the event that Seller elects to proceed under Section 4.3(a) and Purchaser and Seller have failed to agree on the amount by which the Purchase Price shall be reduced (which agreement Seller and Purchaser shall use good faith efforts to reach) by Closing, then, in such event, the dispute shall be submitted to arbitration as provided in Section 7.15.

Notwithstanding the foregoing, in the events that (i) Purchaser conducts an Environmental Assessment on the Properties which discloses environmental matters that Purchaser reasonably believes in good faith may constitute a Material Adverse Environmental Condition; (ii) Purchaser delivers a notice to Seller as required in Section 4.2;
(iii) the cost of remediating the Material Adverse Environmental Condition that is described in Purchaser's notice pursuant to Section 4.2 and/or the Environmental Liabilities attributable to the Material Adverse Environmental Condition that is described in Purchaser's notice pursuant to Section 4.2 exceed three percent (3%) of the unadjusted Purchase Price; and (iv) Purchaser delivers to Seller written notice of termination of this Agreement at least five (5) Business Days prior to Closing Date, then, in the event of the completion and satisfaction of each of the four conditions listed above, Purchaser, at Purchaser's sole election, may unilaterally terminate this Agreement without liability to Seller. If Purchaser terminates this Agreement pursuant to this section, Purchaser shall be entitled to a prompt refund of the full amount of the Deposit from Seller.

Section 4.4 Limitations.

(a) This Article 4 is intended to be the sole and exclusive remedy that Purchaser Indemnitees shall have against Seller Indemnitees with respect to any matter or circumstance relating to Material Adverse Environmental Conditions, Environmental Liabilities, Environmental Laws, the release of materials into the environment, the protection of the environment or health or any matters that Purchaser could have included in a notice delivered pursuant to Section 4.2.

(b) Purchaser, on behalf of itself and each of the other Purchaser Indemnitees, hereby fully releases and discharges the Seller Indemnitees from any and all claims at Law or in equity, known or unknown, whether occurring before the Effective Time, existing at the Effective Time or arising after the Effective Time, contingent or otherwise, with respect to all matters relating to Material Adverse Environmental Conditions, Environmental Liabilities, Environmental Laws, the release of materials into the environment, the protection of the environment or health or any matters that Purchaser could have included in a notice delivered pursuant to Section 4.2 EVEN IF SUCH DAMAGES OR CLAIMS ARE CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT) OF SELLER INDEMNITEES OR THE STRICT LIABILITY OF SELLER INDEMNITEES.

(c) Purchaser acknowledges that Seller has not made and will not make any representation or warranty regarding any matter or circumstance relating to Material Adverse Environmental Conditions, Environmental Laws, the release of materials into the environment or protection of the environment or health, and that nothing in Article 5 or otherwise shall be construed as such a representation or warranty.

Section 7.8 Gas Imbalances and Take-or-Pay Make-up Obligations.

Subject to the adjustment to the Purchase Price as provided in this Section 7.8, Purchaser expressly assumes any and all obligations attributable to gas production imbalances with co-owners of the Properties and gas take-or-pay make-up obligations with purchasers or sellers of natural gas from the Properties. Should Purchaser (i) determine that the gas imbalance information set out on Exhibit 5.13 is inaccurate and (ii) deliver a written notice regarding the gas imbalance to Seller at least five (5) Business Days prior to Closing, Seller shall review Purchaser's information regarding the alleged gas imbalance. If it is determined that there is an inaccuracy as of the Effective Time in the gas imbalance set forth on Exhibit 5.13, then the Purchase Price shall be either increased (if there is aggregate underproduction) or decreased (if there is aggregate overproduction) on the basis of $4.00 per MMBtu. This adjustment to the Purchase Price shall be in full settlement of all production imbalances on the Assets. Notwithstanding anything to the contrary contained in this Section 7.8, there shall be no adjustment to the Purchase Price if it is determined that actual imbalance volumes are within 15% above or below those shown on Exhibit 5.13.

The adjustment to the Purchase Price as set forth in this
Section 7.8 is Purchaser's exclusive remedy for (i) any gas imbalance, (ii) any breach of Seller's representation in
Section 5.13 and (iii) any affirmation of such representations in the certificate of Seller to be delivered pursuant to Section 9.2(d), and, at Closing, Purchaser shall assume Seller's overproduced or underproduced position in the Wells as of the Effective Date, including the responsibility for the payment of royalties with respect to any imbalance and any obligation to balance, whether in cash or in kind.

Section 7.9 Consents and Preferential Rights.

(a) Seller shall promptly prepare and send notices to the holders of any required consents to assignment of any Assets requesting such consents. Seller shall use reasonable efforts to obtain all such consents which are reasonably obtainable by Closing and are required to vest Defensible Title to the Assets in Purchaser. Purchaser shall cooperate with Seller in seeking to obtain such consents. In the event that Seller is unable to obtain such consents that are required to vest Defensible Title to the Assets, Purchaser may elect to treat the unsatisfied consent requirement as a Title Defect and the procedures set forth in Section 3.5(a) shall apply.

(b) Seller shall promptly prepare and send notices to the holders of any applicable preferential rights to purchase any Asset requesting waivers of such preferential rights to purchase. The consideration payable under this Agreement for any particular Assets for purposes of preferential purchase right notices shall be the Allocated Value for such Assets. Seller shall use reasonable efforts to cause such waivers of preferential rights to purchase (or the exercise thereof) to be obtained and delivered prior to Closing. Purchaser shall cooperate with Seller in seeking to obtain such waivers of preferential rights.

If the holder of a preferential right to purchase exercises such right, Seller shall tender to such third party the required interest in the affected Asset at a price equal to the Allocated Value (reduced appropriately, as determined by mutual agreement of Purchaser and Seller, if less than the entire Asset must be tendered), and to the extent that such preferential right to purchase is exercised and such interest in such Asset is actually sold to the third party so exercising such right, the Assets transferred will be treated as if subject to a Title Defect and the procedures set forth in Section 3.5(b) shall apply.

Should a holder of a preferential right to purchase fail to exercise its preferential right to purchase as to any portion of the Assets prior to Closing and the time for exercise or waiver has not yet expired prior to Closing, subject to the remaining provisions of this
Section 7.9, such Assets shall be included in the transaction contemplated by this Agreement at Closing and the following procedures shall be applicable:

(i) An Assignment and Bill of Sale from Seller to Purchaser of the Assets affected by such preferential right to purchase shall be delivered into an escrow account, Purchaser shall take beneficial possession of the affected Assets and Purchaser shall be entitled to all production, income, proceeds, receipts and credits to which Purchaser would be entitled under Section
11.1. Purchaser shall Indemnify Seller Indemnitees against Damages for which Purchaser would be liable under the terms of Sections 11.2 and 11.3 with respect to the affected Assets. Record title to the affected Assets shall not be transferred and the Assignment and Bill of Sale shall not be released to Purchaser from the escrow account until such preferential right to purchase has been waived or has expired. PURCHASER'S INDEMNIFICATION OF SELLER INDEMNITEES SHALL BE PURSUANT TO AND IN ACCORDANCE WITH THE INDEMNIFICATION PROVISIONS SET OUT IN SECTION 11.3(b) AND SHALL INCLUDE, WITHOUT LIMITATION, INDEMNIFICATION AGAINST DAMAGES AND LITIGATION EXPENSES.

(ii) Seller shall continue to use reasonable efforts to obtain the waiver of the preferential right to purchase and shall continue to be responsible for the compliance with the preferential right to purchase.

(iii) Should the holder of the preferential right to purchase exercise same, Purchaser and Seller agree to cause the affected Assets to be transferred to such holder on the terms and provisions set out herein and in the applicable preferential right to purchase provision. In such event, Seller shall pay the Allocated Value, subject to applicable adjustments, for such Asset to Purchaser, and Seller shall be entitled to retain the consideration paid for the affected Asset by the holder of the preferential right to purchase.

(iv) If the preferential right to purchase is waived after the Closing Date or if the time limit for the exercise of the preferential right to purchase expires without being exercised, Seller and Purchaser shall take all reasonable actions necessary to ensure that the affected Assets are promptly conveyed out of escrow to Purchaser.

(v) Once the provisions of subparagraph (iv) have been satisfied and all obligations in connection therewith have been fulfilled, the Closing shall be deemed to have occurred for all purposes hereunder with respect to the affected Assets.

Should any third party bring any suit, action or other proceeding seeking to restrain, enjoin or otherwise prohibit the consummation of the transactions contemplated hereby in connection with a claim to enforce preferential rights, the Assets affected by such suit, action or other proceeding shall be excluded from the Assets transferred at Closing and the Purchase Price shall be reduced by the Allocated Value of such excluded Assets. Promptly after the suit, action or other proceeding is dismissed or settled or a judgment is rendered, Seller shall sell to Purchaser and Purchaser shall purchase from Seller all such Assets not being sold to the third party for a purchase price equal to the Allocated Value of such Assets, adjusted as provided in Section 2.2.

Section 7.10 Tax Matters.

(a) Subject to the provisions below, Seller shall be responsible for all Taxes attributable to all times prior to Effective Time, including without limitation, income Taxes arising as a result of the gain recognized on the transfer of the Assets. Purchaser shall be responsible for all such Taxes attributable to all periods of time at and after the Effective Time.

(b) Seller shall pay to the appropriate Governmental Body all Taxes with respect to the Assets which are required to be paid prior to Closing and shall file all Tax Returns with respect to such Taxes. Seller shall deliver to Purchaser within thirty (30) days of filing copies of all Tax Returns filed by Seller after the Closing Date relating to the Assets and any supporting documentation provided by Seller to any taxing authorities.

(c) Ad valorem, property, severance, production and similar Taxes based upon or measured by the ownership or operation of the Assets or the production of Hydrocarbons therefrom shall be prorated between Purchaser and Seller as provided in Section 1.6. Purchaser shall pay all ad valorem taxes, and within thirty (30) days of paying, Purchaser shall deliver to Seller copies of receipts for payment of ad valorem taxes and any supporting documentation.

Section 11.4 Indemnification Actions.

All claims for indemnification under Section 11.3 shall be asserted and resolved as follows:

(a) For purposes of this Article 11, the term "Indemnifying Party" shall mean the party having an obligation to indemnify the other party pursuant to this Article 11, and the term "Indemnified Party" shall mean the party having the right to be indemnified by the other party pursuant to this Article 11.

(b) To make a claim for indemnification under Section 11.3, an Indemnified Party shall provide to the Indemnifying Party a written notice (the "Indemnification Notice") which specifies the basis of the Indemnified Party's entitlement to indemnification under this Agreement. In the event that the Indemnification Notice is based upon a claim by a third party against the Indemnified Party (a "Third Party Claim"), the Indemnified Party shall provide its Indemnification Notice promptly after the Indemnified Party has actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim; provided that the failure of any Indemnified Party to give notice of a Third Party Claim as provided in this Section 11.4 shall not relieve the Indemnifying Party of its obligations under Section 11.3 except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise prejudices the Indemnifying Party's ability to defend against the Third Party Claim.

(c) The Indemnifying Party shall have thirty (30) days from its receipt of an Indemnification Notice to notify the Indemnified Party whether it will assume the defense of the Indemnified Party against such Third Party Claim at the sole cost and expense of the Indemnifying Party. The Indemnified Party is authorized, prior to and during such thirty (30) day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party.

(d) If the Indemnifying Party assumes the defense of a Third Party Claim pursuant to an Indemnification Notice, the Indemnifying Party shall diligently defend, at its sole cost and expense, the Indemnified Party against the Third Party Claim. The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate in contesting any Third Party Claim which the Indemnifying Party elects to contest. The Indemnified Party may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 11.4(d). An Indemnifying Party shall not, without the written consent of the Indemnified Party, (i) settle any Third Party Claim or consent to the entry of any judgment with respect thereto which does not include an unconditional written release of the Indemnified Party from all liability in respect of such Third Party Claim or (ii) settle any Third Party Claim or consent to the entry of any judgment with respect thereto in any manner that may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity).

(e) If the Indemnifying Party does not assume the defense of the Indemnified Party against a Third Party Claim or assumes the defense, but fails to diligently prosecute or settle the Third Party Claim, then the Indemnified Party shall have the right to defend against the Third Party Claim at the sole cost and expense of the Indemnifying Party, with counsel of the Indemnified Party's choice, subject to the right of the Indemnifying Party to assume the defense of the Third Party Claim at any time prior to settlement or final determination thereof. If the Indemnifying Party has not yet assumed the defense of the Indemnified Party, the Indemnified Party shall send written notice to the Indemnifying Party of any proposed settlement or final determination of the Third Party Claim and the Indemnifying Party shall have the option for ten (10) days following receipt of such notice to (i) assume defense against the Third Party Claim in writing and
(ii) if so assumed, reject, in its reasonable judgment, the proposed settlement or final determination of the Third Party Claim.

(f) In the event that the Indemnification Notice sets forth a claim for Damages based upon an inaccuracy or breach of a representation, warranty or covenant or obligation in this Agreement, the Indemnification Notice shall specify the representation, warranty, covenant or obligation which was inaccurate or breached. In such case, the Indemnifying Party shall have thirty (30) days from its receipt of the Indemnification Notice to (i) cure the Damages complained of, (ii) accept the claim for such Damages or (iii) dispute the claim for such Damages. If the Indemnifying Party does not notify the Indemnified Party within such thirty (30) day period that it has cured the Damages or that it disputes the claim for such Damages, the amount of such Damages shall conclusively be deemed a liability of the Indemnifying Party hereunder.

Section 11.5 Survival.

In the event of Closing:

(a) The representation and warranty of Seller in
Section 3.1(a)(Defensible Title) shall terminate on the Title Claim Date (3.4(a)). The remainder of the representations, warranties, covenants and agreements provided for in this Agreement shall terminate upon Closing except as may otherwise be expressly provided herein.

MDU RESOURCES GROUP, INC.

DIRECTORS' COMPENSATION POLICY

Each Director who is not a full-time employee of the Company shall receive compensation made up of annual cash retainers, common stock and meeting fees. Each Director is also eligible for awards under the 1997 Non-Employee Director Long-Term Incentive Plan.

Annual Retainers and Stock Compensation

The Board service annual cash retainer shall be $20,000. The Lead Director shall receive an annual retainer of $33,000. The annual retainers for service as Chairman of the Compensation, Finance and Nominating and Governance Committees shall be $4,000. The annual retainer for service as Chairman of the Audit Committee shall be $8,000. Such retainers shall be paid in monthly installments.

The Amended and Restated Deferred Compensation Plan for Directors adopted on February 13, 1992, and effective January 1, 1992, as amended, permits a Director to defer all or any portion of the annual cash retainer, as well as meeting fees and any other cash compensation paid for service as a Director. The amount deferred is recorded in each participant's deferred compensation account and credited with income in the manner prescribed in the Plan. For further details, reference is made to the Plan, a copy of which is attached.

Each Director shall receive 2,700 shares of Common Stock on or about the 15th business day following the annual meeting of stockholders, pursuant to the Non-Employee Director Stock Compensation Plan, effective April 25, 1995, as amended, or the 1997 Non-Employee Director Long-Term Incentive Plan. A Director may decline a stock payment for any plan year, in writing in advance of the plan year to which stock payment relates. No cash compensation shall be paid in lieu thereof. By written election a Director may reduce the cash portion of the annual retainer and have that amount applied to the purchase of additional shares. The election must be made on a form provided by the administrative committee and returned to the committee by the last business day of the year prior to the year in which the election is to be effective. The election remains in effect until changed or revoked. No election may be changed or revoked for the current year, but may be changed for a subsequent year. For further details, reference is made to the Non-Employee Director Stock Compensation Plan, a copy of which is attached.

Board and Committee Meeting Fees

The fee for each Board meeting attended shall be $1,500 and for each meeting attended of each Committee of which the Director is a member, and for attendance at the Strategic Planning meeting, shall be $1,500, payable only to Directors who are not full-time employees of the Company.

Travel Expense Reimbursement

All Directors will be reimbursed for reasonable travel expenses including spouse's expenses (providing the spouse participates in ALL business, community, spouse-specific and social events), in connection with attendance at meetings of the Company's Board of Directors and its committees. If the travel expense is related to the reimbursement of commercial airfare, such reimbursement will not exceed full-coach rate. If the travel expense is related to reimbursement of non-commercial airfare, such reimbursement will not exceed the rate for comparable travel by means of commercial airline at the first- class rate.

Directors' Liability

Article Seventeenth of the Company's Restated Certificate of Incorporation provides that no Director of the Company shall be liable to the Company or its stockholders for breach of fiduciary duty as a Director, with certain exceptions stated below.
Section 7.07 of the Company's Bylaws requires the Company to indemnify fully a Director against expenses, attorneys fees, judgments, fines and amounts paid in settlement of any suit, action or proceeding, whether civil or criminal, arising from an action of a Director by reason of the fact that the Director was a Director of MDU Resources Group, Inc.

There are exceptions to these protections: breaches of the Directors' duty of loyalty to the Company or its stockholders, acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law, violation of
Section 174 of the Delaware General Corporation Law (relating to unlawful declaration of dividends and unlawful purchase of the company's stock), and transactions from which the Director derived an improper personal benefit (including short-swing profits under Section 16(b) of the Securities Exchange Act of 1934).

The Company has and does maintain Directors' and Officers' liability insurance coverage with a $100,000,000 limit.

Insurance Coverages

The Company maintains the following insurance for protection of its Directors as they carry out the business of MDU Resources Group, Inc.

1. General liability and automobile liability insurance:

The Directors are afforded coverage under the general liability and automobile liability insurance of the Company. The policy limit is $75,000,000 in excess of self- insured retentions of $500,000 per occurrence for general liability and $250,000 per occurrence for automobile liability; or $1,000,000 per occurrence/$2,000,000 aggregate for general liability and $1,000,000 per occurrence for automobile liability, where we are carrying primary layer insurance coverage.

2. Fiduciary and employee benefit liability insurance:

The Directors are afforded coverage under the fiduciary and employee benefits liability insurance of the Company. The policy has a $35,000,000 limit with no deductible applicable to the Director.

3. Aircraft liability insurance:

The Company's existing aircraft liability insurance policy extends coverage while a non-owned* aircraft is used by a Director in traveling to and from Director or Board committee meetings. This insurance coverage constitutes excess liability coverage in the amount of $200,000,000.

*Non-owned aircraft is defined as: 1) any aircraft registered under a "standard" airworthiness certificate issued by the FAA;
2) aircraft with a seating capacity not exceeding 40 seats; 3) aircraft that are not owned by MDU Resources Group, Inc. or any of its subsidiaries; 4) aircraft that are not partly or wholly owned by or registered in the Director's name or the name of any Director's household member.

4. Travel and sojourn insurance:

All Directors are protected by a group insurance policy with coverage of $250,000 that provides 24-hour accident protection while traveling on Company business.

Coverage in all instances begins at the actual start of a business trip and ends when the Director returns to his/her home or regular place of employment.

The beneficiary of the insurance will be that beneficiary recorded on a beneficiary designation card provided by the Company.

5. Group life insurance:

All outside Directors are protected by a non-contributory group life insurance policy with coverage of $100,000.

The coverage begins the day the Director is elected to the Board of Directors and terminates when the Director ceases to be an outside Director.

A Certificate of Insurance shall be provided to the Director and the beneficiary of the insurance will be that beneficiary recorded on a beneficiary designation card provided by the Company.

This protection is considered taxable compensation under current tax laws. Consequently, the Company will provide each Director annually on Form 1099 the amount of taxable income related to this coverage.
