NOTES TO CONSOLIDATED

FINANCIAL STATEMENTS

June 30, 2014 and 2013

(Unaudited)

Note 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 Company's 2013 Annual Report, and the standards of accounting measurement set forth in the interim reporting guidance in the ASC and any amendments thereto adopted by the 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 2013 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 and are of a normal recurring nature. Depreciation, depletion and amortization expense is reported separately on the Consolidated Statements of Income and therefore is excluded from the other line items within operating expenses. Management has also evaluated the impact of events occurring after June 30, 2014 , up to the date of issuance of these consolidated interim financial statements.

Note 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.

Note 3 - Accounts receivable and allowance for doubtful accounts

Accounts receivable consist primarily of trade receivables from the sale of goods and services which are recorded at the invoiced amount net of allowance for doubtful accounts, and costs and estimated earnings in excess of billings on uncompleted contracts. The total balance of receivables past due 90 days or more was $29.6 million , $35.1 million and $36.4 million at June 30, 2014 and 2013 , and December 31, 2013 , respectively.

The allowance for doubtful accounts is determined through a review of past due balances and other specific account data. Account balances are written off when management determines the amounts to be uncollectible. The Company's allowance for doubtful accounts at June 30, 2014 and 2013 , and December 31, 2013 , was $9.6 million , $10.6 million and $10.1 million , respectively.

Note 4 - Inventories and natural gas in storage

Inventories, other than natural gas in storage for the Company's regulated operations, are stated at the lower of average cost or market value. Natural gas in storage for the Company's regulated operations is generally carried at average cost, or cost using the last-in, first-out method. The portion of the cost of natural gas in storage expected to be used within one year is included in inventories. Inventories consisted of:

The remainder of natural gas in storage, which largely represents the cost of gas required to maintain pressure levels for normal operating purposes, is included in other assets and was $ 47.4 million , $ 48.6 million and $ 48.3 million at June 30, 2014 and 2013 , and December 31, 2013 , respectively.

Note 5 - Impairment of long-lived assets

During the second quarter of 2013, the Company recognized an impairment of coalbed natural gas gathering assets at the pipeline and energy services segment of $14.5 million ( $9.0 million after tax), which is recorded in operation and maintenance expense on the Consolidated Statements of Income. The impairment is related to coalbed natural gas gathering assets located in Wyoming and Montana where there has been a significant decline in natural gas development and production activity largely due to low natural gas prices. The coalbed natural gas gathering assets were written down to fair value that was determined using the income approach. For more information on this nonrecurring fair value measurement, see Note 15 .

Note 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 performance share awards. Common stock outstanding includes issued shares less shares held in treasury. Net income was the same for both the basic and diluted earnings per share calculations. A reconciliation of the weighted average common shares outstanding used in the basic and diluted earnings per share calculations was as follows:

Note 8 - New Accounting Standard

Revenue from Contracts with Customers In May 2014, the FASB issued guidance on accounting for revenue from contracts with customers. The guidance provides for a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry specific guidance. This guidance will be effective for the Company on January 1, 2017. Entities will have the option of using either a full retrospective or modified retrospective approach to adopting the guidance. Under the modified approach, an entity would recognize the cumulative effect of initially applying the guidance with an adjustment to the opening balance of retained earnings in the period of adoption. In addition, the modified approach will require additional disclosures. The Company is evaluating the effects the adoption of the new revenue guidance will have on its results of operations, financial position, cash flows and disclosures, as well as its method of adoption.

Note 10 - Acquisition

On February 10, 2014, the Company entered into agreements to purchase working interests and leasehold positions in oil and natural gas production assets in the southern Powder River Basin of Wyoming. The effective date of the acquisition was October 1, 2013, and the closing occurred on March 6, 2014. The purchase price was $206.3 million , including purchase price adjustments.

The acquisition was accounted for under the acquisition method of accounting and, accordingly, the acquired assets and liabilities assumed have been recorded at their respective fair values as of the date of acquisition. The results of operations of the acquired properties are included in the financial statements since the date of the acquisition. Pro forma financial amounts reflecting the effects of the acquisition are not presented, as such acquisition was not material to the Company's financial position or results of operations.

Note 11 - Discontinued operations

In 2007, Centennial Resources sold CEM to Bicent. In connection with the sale, Centennial Resources agreed to indemnify Bicent and its affiliates from certain third party claims arising out of or in connection with Centennial Resources' ownership or

operation of CEM prior to the sale. In addition, Centennial had previously guaranteed CEM's obligations under a construction contract. The Company incurs legal expenses and had a benefit related to the resolution of this matter in the second quarter of 2014, which are reflected in discontinued operations in the consolidated financial statements and accompanying notes. Discontinued operations are included in the Other category. For more information, see Note 21 .

Note 12 - Equity method investments

Investments in companies in which the Company has the ability to exercise significant influence over operating and financial policies are accounted for using the equity method. At June 30, 2014 , the Company had no significant equity method investments.

In August 2006, MDU Brasil acquired ownership interests in the Brazilian Transmission Lines. The electric transmission lines are primarily in northeastern and southern Brazil. The transmission contracts provide for revenues denominated in the Brazilian Real, annual inflation adjustments and change in tax law adjustments. The functional currency for the Brazilian Transmission Lines is the Brazilian Real.

In 2009, multiple sales agreements were signed for the Company to sell its ownership interests in the Brazilian Transmission Lines. In November 2010, the Company completed the sale of its entire ownership interest in ENTE and ERTE and 59.96 percent of the Company's ownership interest in ECTE. The Company's remaining interest in ECTE is being sold over a four-year period. In August 2013 and 2012, and November 2011, the Company completed the sale of one-fourth of the remaining interest in each year. The Company recognized an immaterial gain in 2013. The Company's remaining ownership interest in ECTE is being accounted for under the cost method.

At June 30, 2013 , the equity method investments had total assets of $114.8 million and long-term debt of $56.2 million . The Company's investment in its equity method investments was approximately $5.5 million , including undistributed earnings of $2.0 million , at June 30, 2013 .

Note 13 - Goodwill and other intangible assets

Amortization expense for amortizable intangible assets for the three and six months ended June 30, 2014 , was $1.0 million and $1.8 million , respectively. Amortization expense for amortizable intangible assets for the three and six months ended June 30, 2013 , was $1.0 million and $1.8 million , respectively. Estimated amortization expense for amortizable intangible assets is $3.3 million in 2014 , $2.5 million in 2015 , $2.2 million in 2016 , $1.9 million in 2017 , $1.0 million in 2018 and $2.2 million thereafter.

Note 14 - Derivative instruments

The Company's policy allows the use of 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. As of June 30, 2014 , the Company had no outstanding foreign currency or interest rate hedges.

The fair value of derivative instruments must be estimated as of the end of each reporting period and is recorded on the Consolidated Balance Sheets as an asset or a liability.

Fidelity

At June 30, 2014 and 2013 , and December 31, 2013 , Fidelity held oil swap and collar agreements with total forward notional volumes of 2.5 million , 3.1 million and 2.9 million Bbl, respectively, and natural gas swap agreements with total forward notional volumes of 11.0 million , 21.4 million and 18.3 million MMBtu, respectively. Fidelity utilizes these derivative instruments to manage a portion of the market risk associated with fluctuations in the price of oil and natural gas on its forecasted sales of oil and natural gas production.

Effective April 1, 2013, Fidelity elected to de-designate all commodity derivative contracts previously designated as cash flow hedges and elected to discontinue hedge accounting prospectively for all of its commodity derivative instruments. When the criteria for hedge accounting is not met or when hedge accounting is not elected, realized gains and losses and unrealized gains and losses are both recorded in operating revenues on the Consolidated Statements of Income. As a result of discontinuing hedge accounting on commodity derivative instruments, gains and losses on the oil and natural gas derivative instruments remain in accumulated other comprehensive income (loss) as of the de-designation date and are reclassified into earnings in future periods as the underlying hedged transactions affect earnings. At April 1, 2013, accumulated other comprehensive income (loss) included $1.8 million of unrealized gains, representing the mark-to-market value of the Company's commodity

derivative instruments that qualified as cash flow hedges as of the balance sheet date. The Company expects to reclassify into earnings from accumulated other comprehensive income (loss) the remaining value related to de-designating commodity derivative instruments over the next 6 months .

Prior to April 1, 2013, changes in the fair value attributable to the effective portion of the hedging instruments, net of tax, were recorded in stockholders' equity as a component of accumulated other comprehensive income (loss). To the extent that the hedges were not effective or did not qualify for hedge accounting, the ineffective portion of the changes in fair market value was recorded directly in earnings. Gains and losses on the oil and natural gas derivative instruments were reclassified from accumulated other comprehensive income (loss) into operating revenues on the Consolidated Statements of Income at the date the oil and natural gas quantities were settled.

There were no components of the derivative instruments' gain or loss excluded from the assessment of hedge effectiveness. Gains and losses must be reclassified into earnings as a result of the discontinuance of cash flow hedges if it is probable that the original forecasted transactions will not occur, and there were no such reclassifications.

Certain of Fidelity's derivative instruments contain cross-default provisions that state if Fidelity or any of its affiliates fails to make payment with respect to certain indebtedness, in excess of specified amounts, the counterparties could require early settlement or termination of the derivative instruments in liability positions. The aggregate fair value of Fidelity's derivative instruments with credit-risk-related contingent features that are in a liability position at June 30, 2014 and 2013 , and December 31, 2013 , were $17.4 million , $1.4 million and $7.5 million , respectively. The aggregate fair value of assets that would have been needed to settle the instruments immediately if the credit-risk-related contingent features were triggered on June 30, 2014 and 2013 , and December 31, 2013 , were $17.4 million , $1.4 million and $7.5 million , respectively.

Centennial

Centennial has historically entered into interest rate derivative instruments to manage a portion of its interest rate exposure on the forecasted issuance of long-term debt. As of June 30, 2014 and 2013 , and December 31, 2013 , Centennial had no outstanding interest rate swap agreements.

Fidelity and Centennial

The gains and losses on derivative instruments were as follows:

Commodity derivatives not designated as hedging instruments:

Over the next 12 months net losses of approximately $535,000 (after tax) are estimated to be reclassified from accumulated other comprehensive income (loss) into earnings, as the hedged transactions affect earnings.

The location and fair value of the gross amount of the Company's derivative instruments on the Consolidated Balance Sheets were as follows:

All of the Company's commodity derivative instruments at June 30, 2014 and 2013 , and December 31, 2013 , were subject to legally enforceable master netting agreements. However, the Company's policy is to not offset fair value amounts for derivative instruments and, as a result, the Company's derivative assets and liabilities are presented gross on the Consolidated Balance Sheets. The gross derivative assets and liabilities (excluding settlement receivables and payables that may be subject to the same master netting agreements) presented on the Consolidated Balance Sheets and the amount eligible for offset under the master netting agreements is presented in the following table:

Note 15 - Fair value measurements

The Company measures its investments in certain fixed-income and equity securities at fair value with changes in fair value recognized in income. The Company anticipates using these investments, which consist of an insurance contract, to satisfy its obligations under its unfunded, nonqualified benefit plans for executive officers and certain key management employees, and invests in these fixed-income and equity securities for the purpose of earning investment returns and capital appreciation. These investments, which totaled $64.4 million , $54.0 million and $62.4 million , at June 30, 2014 and 2013 , and December 31, 2013 , respectively, are classified as Investments on the Consolidated Balance Sheets. The net unrealized gains on these investments were $1.1 million and $2.0 million for the three and six months ended June 30, 2014 , respectively. The net unrealized gains on these investments were $700,000 and $5.1 million for the three and six months ended June 30, 2013 , respectively. The change in fair value, which is considered part of the cost of the plan, is classified in operation and maintenance expense on the Consolidated Statements of Income.

The Company did not elect the fair value option, which records gains and losses in income, for its available-for-sale securities, which include mortgage-backed securities and U.S. Treasury securities. These available-for-sale securities are recorded at fair value and are classified as Investments on the Consolidated Balance Sheets. Unrealized gains or losses are recorded in accumulated other comprehensive income (loss). Details of available-for-sale securities were as follows:



June 30, 2014	Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value

The fair value of the Company's money market funds approximates cost.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The ASC establishes a hierarchy for grouping assets and liabilities, based on the significance of inputs.

The estimated fair values of the Company's assets and liabilities measured on a recurring basis are determined using the market approach.

The Company's Level 2 money market funds consist of investments in short-term unsecured promissory notes and the value is based on comparable market transactions taking into consideration the credit quality of the issuer. The estimated fair value of the Company's Level 2 mortgage-backed securities and U.S. Treasury securities are based on comparable market transactions, other observable inputs or other sources, including pricing from outside sources.

The estimated fair value of the Company's Level 2 insurance contract is based on contractual cash surrender values that are determined primarily by investments in managed separate accounts of the insurer. These amounts approximate fair value. The managed separate accounts are valued based on other observable inputs or corroborated market data.

The estimated fair value of the Company's Level 2 commodity derivative instruments is based upon futures prices, volatility and time to maturity, among other things. Counterparty statements are utilized to determine the value of the commodity derivative instruments and are reviewed and corroborated using various methodologies and significant observable inputs. The Company's and the counterparties' nonperformance risk is also evaluated.

The estimated fair value of the Company's Level 2 interest rate derivative instruments is measured using quoted market prices or pricing models using prevailing market interest rates as of the measurement date. Counterparty statements are utilized to determine the value of the interest rate derivative instruments and are reviewed and corroborated using various methodologies and significant observable inputs. The Company's and the counterparties' nonperformance risk is also evaluated.

Though the Company believes the methods used to estimate fair value are consistent with those used by other market participants, the use of other methods or assumptions could result in a different estimate of fair value. For the six months ended June 30, 2014 and 2013 , there were no transfers between Levels 1 and 2.

The Company's assets and liabilities measured at fair value on a recurring basis were as follows:

The Company applies the provisions of the fair value measurement standard to its nonrecurring, non-financial measurements, including long-lived asset impairments. These assets are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances. The Company reviews the carrying value of its long-lived assets, excluding goodwill and oil and natural gas properties, whenever events or changes in circumstances indicate that such carrying amounts may not be recoverable. During the second quarter of 2013, coalbed natural gas gathering assets were reviewed for impairment and found to be impaired and were written down to their estimated fair value using the income approach. Under this approach, fair value is determined by using the present value of future estimated cash flows. The factors used to determine the estimated future cash flows include, but are not limited to, internal estimates of gathering revenue, future commodity prices and operating costs and equipment salvage values. The estimated cash flows are discounted using a rate that approximates the weighted average cost of capital of a market participant. These fair value inputs are not typically observable. At June 30, 2013, coalbed

natural gas gathering assets were written down to the nonrecurring fair value measurement of $9.7 million . The fair value of these coalbed natural gas gathering assets have been categorized as Level 3 (Significant Unobservable Inputs) in the fair value hierarchy.

The Company's long-term debt is not measured at fair value on the Consolidated Balance Sheets and the fair value is being provided for disclosure purposes only. The fair value was based on discounted future cash flows using current market interest rates. The estimated fair value of the Company's Level 2 long-term debt was as follows:



	Carrying Amount		Fair Value
	(In thousands)
Long-term debt at June 30, 2014	$	2,187,094	$	2,283,351
Long-term debt at June 30, 2013	$	2,006,754	$	2,090,208
Long-term debt at December 31, 2013	$	1,854,563	$	1,912,590

The carrying amounts of the Company's remaining financial instruments included in current assets and current liabilities approximate their fair values.

Note 16 - Long-term debt

On May 8, 2014, the Company amended its revolving credit agreement to increase the borrowing limit to $175.0 million and extend the termination date to May 8, 2019.

The Company entered into a $150.0 million note purchase agreement on January 28, 2014, and issued $50.0 million of Senior Notes on April 15, 2014, with a due date of April 15, 2044, at an interest rate of 5.2 percent . The remaining $100.0 million of Senior Notes was issued on July 15, 2014, with due dates ranging from July 15, 2024 to July 15, 2026, at a weighted average interest rate of 4.3 percent .

On May 8, 2014, Centennial entered into an amended and restated revolving credit agreement which increased the borrowing limit to $650.0 million and extended the termination date to May 8, 2019. The credit agreement contains customary covenants and provisions, including a covenant of Centennial not to permit, as of the end of any fiscal quarter, the ratio of total consolidated debt to total consolidated capitalization to be greater than 65 percent . Other covenants include restrictions on the sale of certain assets, limitations on subsidiary indebtedness and the making of certain loans and investments.

Centennial's revolving credit agreement contains 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, then Centennial will be in default under the revolving credit agreement.

Centennial entered into two separate two year $125.0 million term loan agreements with variable interest rates on March 31, 2014 and April 2, 2014, respectively. These agreements contain customary covenants and default provisions, including covenants not to permit, as of the end of any fiscal quarter, the ratio of Centennial's total debt to total capitalization to be greater than 65 percent . The covenants also include certain limitations on subsidiary indebtedness and restrictions on the sale of certain assets and on the making of certain loans and investments.

In addition, borrowings outstanding that were classified as long-term debt under the Company’s and Centennial’s commercial paper programs totaled $268.0 million at June 30, 2014 , compared to $153.9 million at December 31, 2013, respectively.

Note 20 - Regulatory matters and revenues subject to refund

On April 8, 2014, Montana-Dakota submitted a request to the NDPSC to update the environmental cost recovery rider to reflect actual costs incurred through February 2014 and projected costs through June 2015 related to the recovery of Montana-Dakota's share of the costs resulting from the environmental retrofit required to be installed at the Big Stone Station. The NDPSC approved the proposed rider on July 10, 2014, reflecting an annual amount of $8.6 million to be recovered under the rider. The rider was effective with service rendered on and after July 15, 2014.

On September 18, 2013, Montana-Dakota filed an application with the NDPSC for a natural gas rate increase. Montana-Dakota requested a total increase of $6.8 million annually or approximately 6.4 percent above current rates. The requested increase includes the costs associated with the increased investment in facilities, including ongoing investment in new and replacement distribution facilities, an operations building, automated meter reading and a new customer billing system. An interim increase of $4.3 million annually or approximately 4.0 percent went into effect for service rendered on or after November 17, 2013. On

December 30, 2013, the NDPSC approved a settlement agreement for an increase in the same amount as the interim increase. A hearing on the rate design portion of the case was held February 5, 2014. The NDPSC voted to approve an order approving the allocation of the revenue increase to each rate class and the rate design on April 9, 2014. Final rates were implemented May 1, 2014.

On February 27, 2014, Montana-Dakota filed an application with the NDPSC for approval of an electric generation resource recovery rider for recovery of Montana-Dakota's investment in the 88-MW simple-cycle natural gas turbine and associated facilities currently under construction near Mandan, ND.

Advance determination of prudence and a certificate of public convenience and necessity were received from the NDPSC on April 11, 2012. On March 12, 2014, the NDPSC suspended the filing pending further review. The NDPSC held a hearing regarding this matter on May 28, 2014. The matter is pending before the NDPSC.

On October 31, 2013, WBI Energy Transmission filed a general natural gas rate change application with the FERC based on an increase in investments of $312 million , increased operating costs, and the effect of lower storage and off system volumes. On April 30, 2014, WBI Energy Transmission reached a settlement in principle with FERC Trial Staff and all active parties to resolve the rate case. WBI Energy Transmission filed settlement rates to take effect on an interim basis, effective May 1, 2014, pending final approval of the settlement. On June 4, 2014, WBI Energy Transmission submitted to the FERC an Uncontested Offer of Settlement. On June 11, 2014, the Presiding Administrative Law Judge issued a Certification of Uncontested Settlement recommending FERC approval of the settlement without modification. The matter is pending before the FERC. Based on the adjusted base period volumes filed in the case, the annual increase in revenues is approximately $11.5 million .

Note 21 - Contingencies

The Company is party to claims and lawsuits arising out of its business and that of its consolidated subsidiaries. The Company accrues a liability for those contingencies when the incurrence of a loss is probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. The Company does not accrue liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is probable or reasonably possible and which are material, the Company discloses the nature of the contingency and, in some circumstances, an estimate of the possible loss. The Company had accrued liabilities of $32.1 million , $32.9 million and $29.5 million for contingencies, including litigation, production taxes, royalty claims and environmental matters, at June 30, 2014 and 2013 , and December 31, 2013 , respectively, which include amounts that may have been accrued for matters discussed in Litigation and Environmental matters within this note.

Litigation

Guarantee Obligation Under a Construction Contract Centennial guaranteed CEM's obligations under a construction contract with LPP for a 550-MW combined-cycle electric generating facility near Hobbs, New Mexico. Centennial Resources sold CEM in July 2007 to Bicent. In February 2009, Centennial received a Notice and Demand from LPP under the guarantee agreement alleging that CEM did not meet certain of its obligations under the construction contract and demanding that Centennial indemnify LPP against all losses, damages, claims, costs, charges and expenses arising from CEM's alleged failures. In December 2009, LPP submitted a demand for arbitration of its dispute with CEM to the American Arbitration Association seeking compensatory damages of $149.7 million . An arbitration award was issued January 13, 2012, awarding LPP $22.0 million . Centennial subsequently received a demand from LPP for payment of the arbitration award plus interest and attorneys' fees. An accrual related to the guarantee as a result of the arbitration award was recorded in discontinued operations on the Consolidated Statement of Income in the fourth quarter of 2011. CEM filed a petition with the New York Supreme Court to vacate the arbitration award in favor of LPP. The New York Supreme Court granted CEM's petition to vacate the arbitration award on November 20, 2012, and entered an order and judgment to that effect on June 5, 2013. LPP appealed the order and judgment and on February 20, 2014, the New York Supreme Court Appellate Division ruled the arbitration award was properly vacated. LPP filed a motion with the New York Court of Appeals for leave to appeal the decision of the New York Supreme Court Appellate Division. The motion was denied on June 10, 2014. Due to the vacation of the arbitration award, the accrual that was previously recorded in 2011 was reversed in the fourth quarter of 2012. The effect of this was recorded in discontinued operations on the Consolidated Statement of Income. For more information regarding discontinued operations, see Note 11 .

Construction Materials Until the fall of 2011 when it discontinued active mining operations at the pit, JTL operated the Target Range Gravel Pit in Missoula County, Montana under a 1975 reclamation contract pursuant to the Montana Opencut Mining Act. In September 2009, the Montana DEQ sent a letter asserting JTL was in violation of the Montana Opencut Mining Act by conducting mining operations outside a permitted area. JTL filed a complaint in Montana First Judicial District Court in June 2010, seeking a declaratory order that the reclamation contract is a valid permit under the Montana Opencut Mining Act. The Montana DEQ filed an answer and counterclaim to the complaint in August 2011, alleging JTL was in violation of the Montana

Opencut Mining Act and requesting imposition of penalties of not more than $3.7 million plus not more than $5,000 per day from the date of the counterclaim. The Company believes the operation of the Target Range Gravel Pit was conducted under a valid permit; however, the imposition of civil penalties is reasonably possible. The Company filed an application for amendment of its opencut mining permit and intends to resolve this matter through settlement or continuation of the Montana First Judicial District Court litigation.

Former Employee Litigation On August 6, 2012, a former employee and his spouse filed actions against Connolly-Pacific and others in California Superior Court alleging the former employee contracted acute myelogenous leukemia from exposure to substances while employed as a seaman by the defendants. The plaintiffs request compensatory damages of approximately $23.8 million plus punitive damages, costs and interest. Connolly-Pacific is contesting the claims and believes it has meritorious defenses to them. Connolly-Pacific will seek insurance coverage for defense costs and any liability incurred in the litigation.

Natural Gas Gathering Operations In January 2010, SourceGas filed an application with the Colorado State District Court to compel WBI Energy Midstream to arbitrate a dispute regarding operating pressures under a natural gas gathering contract on one of WBI Energy Midstream's pipeline gathering systems in Montana. WBI Energy Midstream resisted the application and sought a declaratory order interpreting the gathering contract. In May 2010, the Colorado State District Court granted the application and ordered WBI Energy Midstream into arbitration. In October 2010, the arbitration panel issued an award in favor of SourceGas for approximately $26.6 million . The Colorado Court of Appeals issued a decision on May 24, 2012, reversing the Colorado State District Court order compelling arbitration, vacating the final award and remanding the case to the Colorado State District Court to determine SourceGas's claims and WBI Energy Midstream's counterclaims. On remand of the matter to the Colorado State District Court, SourceGas may assert claims similar to those asserted in the arbitration proceeding.

In a related matter, Omimex filed a complaint against WBI Energy Midstream in Montana Seventeenth Judicial District Court in July 2010 alleging WBI Energy Midstream breached a separate gathering contract with Omimex as a result of the increased operating pressures demanded by SourceGas on the same natural gas gathering system. In December 2011, Omimex filed an amended complaint alleging WBI Energy Midstream breached obligations to operate its gathering system as a common carrier under United States and Montana law. WBI Energy Midstream removed the action to the United States District Court for the District of Montana. The parties subsequently settled the breach of contract claim and, subject to final determination on liability, stipulated to the damages on the common carrier claim, for amounts that are not material. A trial on the common carrier claim was held during July 2013, but a decision has not been issued.

Exploration and Production During the ordinary course of its business, Fidelity is subject to audit for various production related taxes by certain state and federal tax authorities for varying periods as well as claims for royalty obligations under lease agreements for oil and gas production. Disputes may exist regarding facts and questions of law relating to the tax and royalty obligations.

On May 15, 2013, Austin Holdings, LLC filed an action against Fidelity in Wyoming State District Court alleging Fidelity violated the Wyoming Royalty Payment Act and implied lease covenants by deducting production costs from and by failing to properly report and pay royalties for coalbed methane gas production in Wyoming. The plaintiff, in addition to declaratory and injunctive relief, seeks class certification for similarly situated persons and an unspecified amount of monetary damages on behalf of the class for unpaid royalties, interest, reporting violations and attorney fees. Fidelity believes it has meritorious defenses against class certification and the claims.

The Company also is subject to other litigation, and actual and potential claims in the ordinary course of its business which may include, but are not limited to, matters involving property damage, personal injury, and environmental, contractual, statutory and regulatory obligations. Accruals are based on the best information available but actual losses in future periods are affected by various factors making them uncertain. After taking into account liabilities accrued for the foregoing matters, management believes that the outcomes with respect to the above issues and other probable and reasonably possible losses in excess of the amounts accrued, while uncertain, will not have a material effect upon the Company's financial position, results of operations or cash flows.

Environmental matters

Portland Harbor Site In December 2000, Knife River - Northwest was named by the EPA as a PRP in connection with the cleanup of a riverbed site adjacent to a commercial property site acquired by Knife River - Northwest from Georgia-Pacific West, Inc. in 1999. The riverbed site is part of the Portland, Oregon, Harbor Superfund Site. 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 and feasibility study of the harbor site are being recorded, and initially paid, through an administrative consent order by the LWG, a group of several entities, which does not include Knife River - Northwest or Georgia-Pacific West, Inc. Investigative

costs are indicated to be in excess of $70 million . It is not possible to estimate the cost of a corrective action plan until the remedial investigation and feasibility study have been completed, the EPA has decided on a strategy and a ROD has been published. Corrective action will be taken after the development of a proposed plan and ROD on the harbor site is issued. Knife River - Northwest also received notice in January 2008 that the Portland Harbor Natural Resource Trustee Council intends to perform an injury assessment to natural resources resulting from the release of hazardous substances at the Harbor Superfund Site. The Portland Harbor Natural Resource Trustee Council indicates the injury determination is appropriate to facilitate early settlement of damages and restoration for natural resource injuries. It is not possible to estimate the costs of natural resource damages until an assessment is completed and allocations are undertaken.

Based upon a review of the Portland Harbor sediment contamination evaluation by the Oregon DEQ and other information available, Knife River - Northwest does not believe it is a Responsible Party. In addition, Knife River - Northwest has notified Georgia-Pacific West, Inc., that it intends to seek indemnity for liabilities incurred in relation to the above matters pursuant to the terms of their sale agreement. Knife River - Northwest has entered into an agreement tolling the statute of limitations in connection with the LWG's potential claim for contribution to the costs of the remedial investigation and feasibility study. By letter in March 2009, LWG stated its intent to file suit against Knife River - Northwest and others to recover LWG's investigation costs to the extent Knife River - Northwest cannot demonstrate its non-liability for the contamination or is unwilling to participate in an alternative dispute resolution process that has been established to address the matter. At this time, Knife River - Northwest has agreed to participate in the alternative dispute resolution process.

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

Manufactured Gas Plant Sites There are three claims against Cascade for cleanup of environmental contamination at manufactured gas plant sites operated by Cascade's predecessors.

The first claim is for contamination at a site in Eugene, Oregon which was received in 1995. There are PRPs in addition to Cascade that may be liable for cleanup of the contamination. Some of these PRPs have shared in the investigation costs. It is expected that these and other PRPs will share in the cleanup costs. Several alternatives for cleanup have been identified, with preliminary cost estimates ranging from approximately $500,000 to $11.0 million . The Oregon DEQ is preparing a staff report which will recommend a cleanup alternative for the site. It is not known at this time what share of the cleanup costs will actually be borne by Cascade; however, Cascade anticipates its proportional share could be approximately 50 percent . Cascade has accrued $1.7 million for remediation of this site. In January 2013, the OPUC approved Cascade's application to defer environmental remediation costs at the Eugene site for a period of 12 months starting November 30, 2012. Cascade received an order reauthorizing the deferred accounting for the 12 months starting November 30, 2013.

The second claim is for contamination at a site in Bremerton, Washington which was received in 1997. A preliminary investigation has found soil and groundwater at the site contain contaminants requiring further investigation and cleanup. EPA conducted a Targeted Brownfields Assessment of the site and released a report summarizing the results of that assessment in August 2009. The assessment confirms that contaminants have affected soil and groundwater at the site, as well as sediments in the adjacent Port Washington Narrows. Alternative remediation options have been identified with preliminary cost estimates ranging from $340,000 to $6.4 million . Data developed through the assessment and previous investigations indicates the contamination likely derived from multiple, different sources and multiple current and former owners of properties and businesses in the vicinity of the site may be responsible for the contamination. In April 2010, the Washington Department of Ecology issued notice it considered Cascade a PRP for hazardous substances at the site. In May 2012, the EPA added the site to the National Priorities List of Superfund sites. Cascade has entered into an administrative settlement agreement and consent order with the EPA regarding the scope and schedule for a remedial investigation and feasibility study for the site. Cascade has accrued $12.6 million for the remedial investigation, feasibility study and remediation of this site. In April 2010, Cascade filed a petition with the WUTC for authority to defer the costs, which are included in other noncurrent assets, incurred in relation to the environmental remediation of this site until the next general rate case. The WUTC approved the petition in September 2010, subject to conditions set forth in the order.

The third claim is for contamination at a site in Bellingham, Washington. Cascade received notice from a party in May 2008 that Cascade may be a PRP, along with other parties, for contamination from a manufactured gas plant owned by Cascade and its predecessor from about 1946 to 1962. The notice indicates that current estimates to complete investigation and cleanup of the site exceed $8.0 million . Other PRPs have reached an agreed order and work plan with the Washington Department of Ecology for completion of a remedial investigation and feasibility study for the site. A report documenting the initial phase of the remedial investigation was completed in June 2011. There is currently not enough information available to estimate the potential liability to Cascade associated with this claim although Cascade believes its proportional share of any liability will be relatively small in comparison to other PRPs. The plant manufactured gas from coal between approximately 1890 and 1946. In

1946, shortly after Cascade's predecessor acquired the plant, it converted the plant to a propane-air gas facility. There are no documented wastes or by-products resulting from the mixing or distribution of propane-air gas.

Cascade has received notices from and entered into agreement with certain of its insurance carriers that they will participate in defense of Cascade for these contamination claims subject to full and complete reservations of rights and defenses to insurance coverage. To the extent these claims are not covered by insurance, Cascade will seek recovery through the OPUC and WUTC of remediation costs in its natural gas rates charged to customers. The accruals related to these matters are reflected in regulatory assets.

Guarantees

Centennial guaranteed CEM's obligations under a construction contract. For more information, see Litigation in this note.

In connection with the sale of the Brazilian Transmission Lines, as discussed in Note 12 , Centennial has agreed to guarantee payment of any indemnity obligations of certain of the Company's indirect wholly owned subsidiaries who are the sellers in three purchase and sale agreements for periods ranging up to 10 years from the date of sale. The guarantees were required by the buyers as a condition to the sale of the Brazilian Transmission Lines.

WBI Holdings has guaranteed certain of Fidelity's oil and natural gas swap agreement obligations. There is no fixed maximum amount guaranteed in relation to the oil and natural gas swap agreements as the amount of the obligation is dependent upon oil and natural gas commodity prices. The amount of derivative activity entered into by the subsidiary is limited by corporate policy. The guarantees of the oil and natural gas swap agreements at June 30, 2014 , expire in the years ranging from 2014 to 2015; however, Fidelity continues to enter into additional derivative instruments and, as a result, WBI Holdings from time to time may issue additional guarantees on these derivative instruments. The amount outstanding by Fidelity was $14.5 million and was reflected on the Consolidated Balance Sheet at June 30, 2014 . 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 construction contracts, natural gas transportation and sales agreements, gathering contracts and certain other guarantees. At June 30, 2014 , the fixed maximum amounts guaranteed under these agreements aggregated $76.7 million . The amounts of scheduled expiration of the maximum amounts guaranteed under these agreements aggregate $21.2 million in 2014 ; $35.7 million in 2015 ; $700,000 in 2016 ; $600,000 in 2017 ; $500,000 in 2018 ; $500,000 in 2019 ; $13.5 million , which is subject to expiration on a specified number of days after the receipt of written notice; and $4.0 million , which has no scheduled maturity date. The amount outstanding by subsidiaries of the Company under the above guarantees was $200,000 and was reflected on the Consolidated Balance Sheet at June 30, 2014 . 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.

Certain subsidiaries have outstanding letters of credit to third parties related to insurance policies and other agreements, some of which are guaranteed by other subsidiaries of the Company. At June 30, 2014 , the fixed maximum amounts guaranteed under these letters of credit, aggregated $36.3 million . In 2014 and 2015 , $7.0 million and $29.3 million , respectively, of letters of credit are scheduled to expire. There were no amounts outstanding under the above letters of credit at June 30, 2014 .

WBI Holdings has an outstanding guarantee to WBI Energy Transmission. This guarantee is related to a natural gas transportation and storage agreement that guarantees the performance of Prairielands. At June 30, 2014 , the fixed maximum amount guaranteed under this agreement was $4.0 million and is scheduled to expire in 2016. In the event of Prairielands' default in its payment obligations, WBI Holdings would be required to make payment under its guarantee. The amount outstanding by Prairielands under the above guarantee was $1.1 million . The amount outstanding under this guarantee was not reflected on the Consolidated Balance Sheet at June 30, 2014 , because this intercompany transaction was eliminated in consolidation.

In addition, Centennial, Knife River and MDU Construction Services have issued guarantees to third parties related to the routine purchase of maintenance items, materials and lease obligations 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 these obligations, Centennial, Knife River and MDU Construction Services would be required to make payments under these guarantees. Any amounts outstanding by subsidiaries of the Company for these guarantees were reflected on the Consolidated Balance Sheet at June 30, 2014 .

In the normal course of business, Centennial has surety bonds related to construction contracts and reclamation obligations of its subsidiaries. In the event a subsidiary of Centennial does not fulfill a bonded obligation, Centennial would be responsible to

the surety bond company for completion of the bonded contract or obligation. A large portion of the surety bonds 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. At June 30, 2014 , approximately $666.9 million of surety bonds were outstanding, which were not reflected on the Consolidated Balance Sheet.

Variable interest entities

The Company evaluates its arrangements and contracts with other entities to determine if they are VIEs and if so, if the Company is the primary beneficiary.

Dakota Prairie Refining, LLC On February 7, 2013, WBI Energy and Calumet formed a limited liability company, Dakota Prairie Refining, and entered into an operating agreement to develop, build and operate Dakota Prairie Refinery in southwestern North Dakota. WBI Energy and Calumet each have a 50 percent ownership interest in Dakota Prairie Refining. WBI Energy's and Calumet's capital commitments, based on a total project cost of $300.0 million , under the agreement are $150.0 million and $75.0 million , respectively. Capital commitments in excess of $300.0 million are expected to be shared equally between WBI Energy and Calumet. The total project cost is currently estimated at $350 million . Dakota Prairie Refining entered into a term loan for project debt financing of $75.0 million on April 22, 2013. The operating agreement provides for allocation of profits and losses consistent with ownership interests; however, deductions attributable to project financing debt will be allocated to Calumet. Calumet's future cash distributions from Dakota Prairie Refining will be decreased by the principal and interest to be paid on the project debt, while the cash distributions to WBI Energy will not be decreased. Pursuant to the operating agreement, Centennial agreed to guarantee Dakota Prairie Refining's obligation under the term loan.

Dakota Prairie Refining has been determined to be a VIE, and the Company has determined that it is the primary beneficiary as it has an obligation to absorb losses that could be potentially significant to the VIE through WBI Energy's equity investment and Centennial's guarantee of the third-party term loan. Accordingly, the Company consolidates Dakota Prairie Refining in its financial statements and records a noncontrolling interest for Calumet's ownership interest.

Construction of Dakota Prairie Refinery began in early 2013 and the plant is not yet operational. Therefore, the results of operations of Dakota Prairie Refining did not have a material effect on the Company's Consolidated Statements of Income. The assets of Dakota Prairie Refining shall be used solely for the benefit of Dakota Prairie Refining. The total assets and liabilities of Dakota Prairie Refining reflected on the Company's Consolidated Balance Sheets were as follows:

Fuel Contract On October 10, 2012, the Coyote Station entered into a new coal supply agreement with Coyote Creek that will replace a coal supply agreement expiring in May 2016. The new agreement provides for the purchase of coal necessary to supply the coal requirements of the Coyote Station for the period May 2016 through December 2040.

The new coal supply agreement creates a variable interest in Coyote Creek due to the transfer of all operating and economic risk to the Coyote Station owners, as the agreement is structured so the price of the coal will cover all costs of operations as well as future reclamation costs. The Coyote Station owners are also providing a guarantee of the value of the assets of Coyote Creek as they would be required to buy the assets at book value should they terminate the contract prior to the end of the contract term and are providing a guarantee of the value of the equity of Coyote Creek in that they are required to buy the entity at the end of the contract term at equity value. Although the Company has determined that Coyote Creek is a VIE, the Company has concluded that it is not the primary beneficiary of Coyote Creek because the authority to direct the activities of the entity is shared by the four unrelated owners of the Coyote Station, with no primary beneficiary existing. As a result, Coyote Creek is not required to be consolidated in the Company's financial statements.

At June 30, 2014 , Coyote Creek was not yet operational. The assets and liabilities of Coyote Creek and exposure to loss as a result of the Company's involvement with the VIE, based on the Company's ownership percentage, at June 30, 2014 , was $9.7 million .

Note 22 - Subsequent Events

The Company entered into a $150.0 million note purchase agreement on January 28, 2014 . On April 15, 2014 , the Company issued $50.0 million of Senior Notes with a due date of April 15, 2044 , at an interest rate of 5.2 percent . The remaining $100.0 million of Senior Notes was issued on July 15, 2014 , with due dates ranging from July 15, 2024 to July 15, 2026, at a weighted average interest rate of 4.3 percent .

Fidelity entered into a purchase and sale agreement on July 17, 2014, to sell certain oil and natural gas properties in Mountrail County, North Dakota for a sale price of approximately $200.0 million , subject to accounting and purchase price adjustments customary with dispositions of this type. The effective date of the disposition is May 1, 2014, with the expected closing date to occur on or before September 30, 2014, conditioned upon the buyer completing a due diligence process, including environmental reviews, and both parties satisfying other standard closing conditions.

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

Overview

The Company's strategy is to apply its expertise in energy and transportation infrastructure industries to increase market share, increase profitability and enhance shareholder value through:


•	Organic growth as well as a continued disciplined approach to the acquisition of well-managed companies and properties


•	The elimination of system-wide cost redundancies through increased focus on integration of operations and standardization and consolidation of various support services and functions across companies within the organization


•	The development of projects that are accretive to earnings per share and return on invested capital

The Company has capabilities to fund its growth and operations through various sources, including internally generated funds, commercial paper facilities, revolving credit facilities and the issuance from time to time of debt and equity securities. For more information on the Company's net capital expenditures, see Liquidity and Capital Commitments.

The key strategies for each of the Company's business segments and certain related business challenges are summarized below. For a summary of the Company's business segments, see Note 18 .

Key Strategies and Challenges

Electric and Natural Gas Distribution

Strategy Provide safe and reliable competitively priced energy and related services to customers. The electric and natural gas distribution segments continually seek opportunities to retain, grow and expand their customer base through extensions of existing operations, including building and upgrading electric generation and transmission and natural gas systems, and through selected acquisitions of companies and properties at prices that will provide stable cash flows and an opportunity for the Company to earn a competitive return on investment.

Challenges Both segments are subject to extensive regulation in the state jurisdictions where they conduct operations with respect to costs and permitted returns on investment as well as subject to certain operational, system integrity and environmental regulations. These regulations can require substantial investment to upgrade facilities. The ability of these segments to grow through acquisitions is subject to significant competition. In addition, the ability of both segments to grow service territory and customer base is affected by the economic environment of the markets served and competition from other energy providers and fuels. The construction of any new electric generating facilities, transmission lines and other service facilities are subject to increasing cost and lead time, extensive permitting procedures, and federal and state legislative and regulatory initiatives, which will necessitate increases in electric energy prices. Legislative and regulatory initiatives to increase renewable energy resources and reduce GHG emissions could impact the price and demand for electricity and natural gas.

Pipeline and Energy Services

Strategy Utilize the segment's existing expertise in energy infrastructure and related services to increase market share and profitability through optimization of existing operations, internal growth, investments in and acquisitions of energy-related assets and companies. Incremental and new growth opportunities include: access to new energy sources for storage, gathering and transportation services; expansion of existing gathering, transmission and storage facilities; incremental expansion of pipeline capacity; expansion of midstream business to include liquid pipelines and processing/refining activities; and expansion of related energy services.

Challenges Challenges for this segment include: energy price volatility; tight natural gas basis differentials; environmental and regulatory requirements; recruitment and retention of a skilled workforce; and competition from other pipeline and energy services companies.

Exploration and Production

Strategy Apply technology and utilize existing exploration and production expertise, with a focus on operated properties, to increase production and reserves from existing leaseholds, and to seek additional reserves and production opportunities both in new and existing areas to further expand the segment's asset base. By optimizing existing operations and taking advantage of new and incremental growth opportunities, this segment is focused on balancing the oil and natural gas commodity mix to maximize profitability with its goal to add value by increasing both reserves and production over the long term so as to generate competitive returns on investment.

Challenges Volatility in natural gas and oil prices; timely receipt of necessary permits and approvals; environmental and regulatory requirements; recruitment and retention of a skilled workforce; availability of drilling rigs, materials, auxiliary equipment and industry-related field services; inflationary pressure on development and operating costs; and competition from other exploration and production companies are ongoing challenges for this segment.

Construction Materials and Contracting

Strategy Focus on high-growth strategic markets located near major transportation corridors and desirable mid-sized metropolitan areas; strengthen long-term, strategic aggregate reserve position through purchase and/or lease opportunities; enhance profitability through cost containment, margin discipline and vertical integration of the segment's operations; develop and recruit talented employees; and continue growth through organic and acquisition opportunities. Vertical integration allows the segment to manage operations from aggregate mining to final lay-down of concrete and asphalt, with control of and access to permitted aggregate reserves being significant. A key element of the Company's long-term strategy for this business is to further expand its market presence in the higher-margin materials business (rock, sand, gravel, liquid asphalt, asphalt concrete, ready-mixed concrete and related products), complementing and expanding on the Company's expertise.

Challenges Recruitment and retention of key personnel and volatility in the cost of raw materials such as diesel, gasoline, liquid asphalt, cement and steel, continue to be a concern. This business unit expects to continue cost containment efforts, positioning its operations for the resurgence in the private market, while continuing the emphasis on industrial, energy and public works projects.

Construction Services

Strategy Provide a superior return on investment by: building new and strengthening existing customer relationships; effectively controlling costs; retaining, developing and recruiting talented employees; and focusing our efforts on projects that will permit higher margins while properly managing risk.

Challenges This segment operates in highly competitive markets with many jobs subject to competitive bidding. Maintenance of effective operational and cost controls, retention of key personnel, managing through downturns in the economy and effective management of working capital are ongoing challenges.

For more information on the risks and challenges the Company faces as it pursues its growth strategies and other factors that should be considered for a better understanding of the Company's financial condition, see Item 1A - Risk Factors, as well as Part I, Item 1A - Risk Factors in the 2013 Annual Report. For more information on each segment's key growth strategies, projections and certain assumptions, see Prospective Information. For information pertinent to various commitments and contingencies, see Notes to Consolidated Financial Statements.

Three Months Ended June 30, 2014 and 2013 Consolidated earnings for the quarter ended June 30, 2014 , increased $7.6 million ( 16 percent ) from the comparable prior period largely due to:


•	The absence of the 2013 natural gas gathering asset impairment of $9.0 million (after tax) and higher earnings from the Company's interest in the Pronghorn oil and natural gas gathering and processing assets at the pipeline and energy services business


•	Higher retail sales margins at the electric business

Partially offsetting these increases were an unrealized loss on commodity derivatives of $3.3 million (after tax) in 2014 compared to an unrealized gain on commodity derivatives of $8.2 million (after tax) in 2013, a loss of $7.3 million (after tax) resulting from a realized commodity derivative loss in 2014 compared to a realized commodity derivative gain in 2013 and higher depreciation, depletion and amortization expense; partially offset by increased oil production of 14 percent and increased average realized oil prices of 6 percent, excluding gain/loss on commodity derivatives, at the exploration and production business.

Six Months Ended June 30, 2014 and 2013 Consolidated earnings for the six months ended June 30, 2014 , increased $7.7 million ( 8 percent ) from the comparable prior period largely due to:


•	The absence of the 2013 natural gas gathering asset impairment of $9.0 million (after tax), as well as higher earnings from the Company's interest in the Pronghorn oil and natural gas gathering and processing assets at the pipeline and energy services business


•	Higher workloads and margins in the Western region at the construction services business

Partially offsetting these increases were a loss of $14.3 million (after tax) resulting from a realized commodity derivative loss in 2014 compared to a realized commodity derivative gain in 2013, an unrealized loss on commodity derivatives of $7.5 million (after tax) in 2014 compared to an unrealized gain on commodity derivatives of $4.6 million (after tax) in 2013, higher depreciation, depletion and amortization expense, as well as decreased natural gas production of 19 percent; partially offset by higher oil production of 14 percent and higher average realized natural gas prices of 52 percent, excluding gain/loss on commodity derivatives, at the exploration and production business.

Three Months Ended June 30, 2014 and 2013 Electric earnings increased $3.4 million ( 77 percent ) due to:


•	Higher retail sales margins, the result of higher rates, primarily due to the recovery of costs of environmental upgrades; as well as increased sales volumes of 4 percent, primarily to commercial and industrial customers


•	Higher other income, which includes $800,000 (after tax) largely related to allowance for funds used during construction

Partially offsetting these increases were higher depreciation, depletion and amortization expense of $400,000 (after tax), primarily related to increased property, plant and equipment balances.

Six Months Ended June 30, 2014 and 2013 Electric earnings increased $4.7 million ( 32 percent ) due to:


•	Higher retail sales margins, the result of higher rates, primarily due to the recovery of costs of environmental upgrades; and increased sales volumes of 8 percent to all customer classes


•	Higher other income, which includes $1.2 million (after tax) largely related to allowance for funds used during construction

Partially offsetting these increases were higher operation and maintenance expense, which includes $1.4 million (after tax) primarily related to higher benefit-related costs and contract services, along with higher depreciation, depletion and amortization expense of $400,000 (after tax), as previously discussed.

Three Months Ended June 30, 2014 and 2013 The natural gas distribution business experienced a seasonal loss of $4.5 million compared to a seasonal loss of $5.9 million a year ago (a 24 percent improvement). The improvement was largely due to:


•	Higher sales margins, including approved rate increases effective in late 2013, offset in part by lower volumes, primarily due to warmer weather


•	Lower regulated operation and maintenance expense, which includes $500,000 (after tax) largely related to decreased benefit-related costs and other expenses, offset in part by increased contract services


•	Higher other income, which includes $500,000 (after tax) largely related to allowance for funds used during construction

Partially offsetting these increases were higher depreciation, depletion and amortization expense of $700,000 (after tax), primarily resulting from higher property, plant and equipment balances.

The previous table also reflects higher revenue and higher operation and maintenance expense related to nonregulated activity.

Six Months Ended June 30, 2014 and 2013 Natural gas distribution earnings decreased $3.8 million ( 14 percent ) due to:


•	The absence in 2014 of the $2.8 million (after tax) gain on the sale of Montana-Dakota's nonregulated appliance service and repair business in March 2013


•	Higher operation and maintenance expense, which includes $2.7 million (after tax) largely related to higher payroll and benefit-related costs and higher contract services


•	Higher depreciation, depletion and amortization expense of $1.4 million (after tax), as previously discussed

Partially offsetting these decreases were higher retail sales margins, largely resulting from approved rate increases effective in late 2013; as well as higher other income, which includes $800,000 (after tax) largely related to allowance for funds used during construction.

Three Months Ended June 30, 2014 and 2013 Pipeline and energy services recognized earnings of $5.8 million compared to a loss of $6.4 million for the comparable prior period due to:


•	Absence of the 2013 natural gas gathering asset impairment of $9.0 million (after tax)


•	Higher earnings from the Company's interest in the Pronghorn oil and natural gas gathering and processing assets, primarily due to higher volumes


•	Higher earnings of $1.2 million (after tax) due to increased transportation rates


•	Lower operation and maintenance expense (excluding the asset impairment and Pronghorn-related expense), which includes $800,000 (after tax) largely related to lower legal-related costs

These increases were partially offset by lower storage services revenue of $700,000 (after tax), largely due to lower average storage balances and lower rates.

Six Months Ended June 30, 2014 and 2013 Pipeline and energy services recognized earnings of $10.1 million compared to a loss of $4.1 million for the comparable prior period due to:


•	Absence of the 2013 natural gas gathering asset impairment of $9.0 million (after tax)


•	Higher earnings from the Company's interest in the Pronghorn oil and natural gas gathering and processing assets, primarily due to higher volumes and prices


•	Higher earnings of $2.0 million (after tax) due to increased transportation rates and volumes


•	Lower operation and maintenance expense (excluding the asset impairment and Pronghorn-related expense), which includes $1.1 million (after tax) largely related to lower legal-related costs

These increases were partially offset by lower storage services revenue of $1.3 million (after tax), largely due to lower average storage balances.

Results also reflect higher operating revenues and higher purchased natural gas sold, both related to higher natural gas prices.

◦

The Company filed an application February 27, 2014, with the NDPSC requesting approval for a generation resource recovery rider for $7.4 million to recover costs associated with the 88-MW simple-cycle natural gas turbine and associated facilities currently under construction. The estimated project cost is $77 million and the projected in-service date is third quarter 2014. It is located adjacent to the Company's Heskett Generating Station near Mandan, North Dakota. The capacity is necessary to meet the requirements of the Company's integrated electric system customers and will be a partial replacement for third-party contract capacity expiring in 2015. On March 12, 2014, the NDPSC suspended the filing pending further review and a hearing was held May 28, 2014. A work session was held July 18, 2014, to discuss the request. Advance determination of prudence and a Certificate of Public Convenience and Necessity have been received from the NDPSC. For more information, see Note 20 .


◦	The Company filed an application September 18, 2013, with the NDPSC for a natural gas rate increase, as discussed in Note 20 .

◦

The Company submitted a request April 8, 2014, to the NDPSC to update an environmental cost recovery rider related to costs resulting from the environmental retrofit required to be installed at the Big Stone Station to reflect actual costs incurred through February 2014 and projected costs through June 2015. The NDPSC approved the rider July 10, 2014, for recovery of $8.6 million annually. The Company's share of the cost for the installation is approximately $90 million and is expected to be complete in 2015. The NDPSC had earlier approved advance determination of prudence for recovery of costs on the system. For more information, see Note 20 .


•	Investments are being made in 2014 totaling approximately $80 million to serve the growing electric and natural gas customer base associated with the Bakken oil development where customer growth is substantially higher than the national average.


•	The Company is engaged in a 30-mile, approximately $60 million natural gas line project into the Hanford Nuclear Site in Washington.

•

The Company, along with a partner, expects to build a 345-kilovolt transmission line from Ellendale, North Dakota, to Big Stone City, South Dakota, about 160 miles. The Company’s share of the cost is estimated at approximately $170 million. The project is a MISO multi-value project. A route application was filed in August 2013 with the state of South Dakota, and in October 2013 with the state of North Dakota. A route permit was approved in North Dakota on July 10, 2014. A route permit hearing was held June 10, 2014, in South Dakota. The project is expected to be complete in 2019.


•	The Company is analyzing potential projects for accommodating load growth in its industrial and agricultural sectors, with company- and customer-owned pipeline facilities designed to serve existing facilities served by fuel oil or propane, and to serve new customers.


•	The Company is involved with a number of pipeline projects to enhance the reliability and deliverability of its system in the Pacific Northwest and Idaho.

Pipeline and energy services

•

The Company, in conjunction with Calumet, formed Dakota Prairie Refining, to develop, build and operate Dakota Prairie Refinery. Construction began on the facility in late March 2013 and it is approximately 75 percent complete. When complete, it will process Bakken crude into diesel, which will be marketed within the Bakken region. Other by-products, naphtha and atmospheric tower bottoms, will be railed to other areas. The total project cost estimate is approximately $350 million, with a projected in-service date in late 2014. EBITDA for the first year of operation is projected to be in the range of $70 million to $90 million, to be shared equally with Calumet.

•

In January 2014, the Company launched an open season to obtain capacity commitments on a proposed 375-mile natural gas pipeline from western North Dakota to northwestern Minnesota to transport natural gas to markets in eastern North Dakota, Minnesota, Wisconsin, Michigan and other Midwest markets. The pipeline is expected to provide access to additional markets via interconnections with pipelines owned by Great Lakes Gas Transmission, Viking Gas Transmission and potentially TransCanada, in northwestern Minnesota. An interconnection with the Alliance Pipeline system in eastern North Dakota also is possible. Initially the pipeline would transport approximately 400 MMcf per day of natural gas and could be expanded to more than 500 MMcf per day. The project investment is estimated to be approximately $650 million. The open season ended May 30, 2014, and the Company is evaluating the responses received and working with those parties as well as other interested parties. The Company expects to provide a status update on its efforts by this fall. If the project moves forward, following the receipt of necessary permits and regulatory approvals, construction on the new pipeline could begin in 2016 with completion expected in 2017.


•	On October 31, 2013, WBI Energy Transmission filed a Section 4 rate case with the FERC, as discussed in Note 20 .

•

The Company is engaged in various natural gas pipeline projects to be constructed in 2014, including connections for the planned Garden Creek II natural gas processing plant in the Bakken, an expansion of its transmission system to increase capacity to the Black Hills, and a 24-mile pipeline and related processing facilities to transport Fidelity's Paradox basin natural gas production. The total cost for these projects is approximately $50 million.


•	The Company continues to pursue expansion of facilities and services offered to customers. Energy development within its geographic region is expanding, most notably in the Bakken area, where the Company owns an extensive natural gas pipeline system. Ongoing energy development is expected to continue to provide growth opportunities for this business.

Exploration and production


•	The Company expects to spend approximately $620 million in gross capital expenditures in 2014, which is likely to be partially offset by the expected sale of certain Mountrail County, North Dakota assets and other planned asset sales this year.

•

For 2014, the Company now expects a 10 to 15 percent increase in oil production, lower than its earlier estimate primarily the result of the expected sale of certain Mountrail County assets. NGL production is expected to decline 20 to 25 percent and natural gas production is expected to be 20 to 25 percent lower compared to a year ago. The declines are primarily the result of the divestment of certain non-strategic natural gas-based properties in 2013 and the expected divestment of the Company's South Texas assets this year. The vast majority of the capital program is focused on growing oil production.


•	The Company has a total of three operated drilling rigs deployed on its acreage with two deployed in the Bakken area and one in the Paradox area. There are two non-operated rigs deployed on the Company's Powder River Basin acreage.


•	Bakken areas


◦	The Company owns a total of approximately 108,500 net acres of leaseholds in Mountrail and Stark counties, North Dakota and Richland County, Montana, assuming the divestment of 4,363 net acres in Mountrail County. The Middle Bakken and Three Forks formations are targeted in North Dakota and the Red River formation is targeted in Montana.


◦	Capital expenditures are expected to total approximately $125 million in 2014, excluding the proceeds from the pending sale of Mountrail County acreage.


◦	Net oil production for the second quarter was approximately 7,600 BOPD.


◦	The Company has been testing two alternative completion techniques; plug and perforation and coil tubing with cemented liners. The coil tubing with cemented liner technique is encouraging and focus is on optimizing this approach.


•	Paradox Basin, Utah


◦	The Company owns approximately 140,000 net acres of leaseholds, including its acquisitions of 35,000 net acres of leaseholds in February 2014, and 11,000 net acres of leaseholds in April 2014 and has an option to earn another 20,000 acres.


◦	Capital expenditures are expected to total approximately $150 million in 2014.


◦	Well costs range from $8 million to $11 million per well depending upon lateral lengths. Estimated ultimate recoveries are increasing with the upper range now at 1.7 MMBbls of oil per well.


◦	The Cane Creek Unit 12-1 well has cumulative production of 740 MBbls of oil since it began producing in September 2012. Artificial lift facilities have recently been installed.

Net oil production for second quarter was approximately 3,290 BOPD, up 42 percent from second quarter 2013 and down 8 percent from first quarter 2014. Operational issues/downtime on several high-rate wells occurred during the quarter, which have now been broadly resolved with the installation of artificial lift. Drilling on multi-well pads, which defers completion, and two low-rate fringe acreage tests have delayed production growth. Higher growth is expected in third quarter 2014. The second drilling rig will return when sufficient permits are in place to sustain two rigs.


◦	The Company's understanding of this play continues to improve. It is anticipated that this field will play a key role in the Company's oil growth strategy.

NEW ACCOUNTING STANDARDS

For information regarding new accounting standards, see Note 8 , which is incorporated by reference.

CRITICAL ACCOUNTING POLICIES INVOLVING SIGNIFICANT ESTIMATES

The Company's critical accounting policies involving significant estimates include impairment testing of oil and natural gas properties, impairment testing of long-lived assets and intangibles, revenue recognition, pension and other postretirement benefits, and income taxes. There were no material changes in the Company's critical accounting policies involving significant estimates from those reported in the 2013 Annual Report. For more information on critical accounting policies involving significant estimates, see Part II, Item 7 in the 2013 Annual Report.

LIQUIDITY AND CAPITAL COMMITMENTS

At June 30, 2014 , the Company had cash and cash equivalents of $ 90.3 million and available capacity of $669.8 million under the outstanding credit facilities of the Company and its subsidiaries. The Company expects to meet its obligations for debt maturing within one year from various sources, including internally generated funds; the Company's credit facilities, as described later; and through the issuance of long-term debt and the Company's equity securities.

Cash flows

Operating activities The changes in cash flows from operating activities generally follow the results of operations as discussed in Financial and Operating Data and also are affected by changes in working capital.

Cash flows provided by operating activities in the first six months of 2014 decreased $23.4 million from the comparable period in 2013 primarily due to higher income taxes paid.

Investing activities Cash flows used in investing activities in the first six months of 2014 increased $175.2 million from the comparable period in 2013 . The increase in cash flows used in investing activities was primarily due to higher acquisition-related capital expenditures at the exploration and production business; offset in part by lower ongoing capital expenditures at the exploration and production business.

Financing activities Cash flows provided by financing activities in the first six months of 2014 increased $177.5 million from the comparable period in 2013 . The increase in cash flows provided by financing activities was primarily due to the issuance of $132.3 million of common stock; as well as lower repayment of long-term debt of $102.9 million. Partially offsetting this increase were higher dividends paid in 2014 compared to 2013 due to the acceleration of the first quarter 2013 quarterly common stock dividend to 2012.

Defined benefit pension plans

There were no material changes to the Company's qualified noncontributory defined benefit pension plans from those reported in the 2013 Annual Report. For more information, see Note 19 and Part II, Item 7 in the 2013 Annual Report.

Capital expenditures

Net capital expenditures for the first six months of 2014 were $579.2 million and are estimated to be approximately $863 million for 2014 . Estimated capital expenditures include:


•	System upgrades


•	Routine replacements


•	Service extensions


•	Routine equipment maintenance and replacements


•	Buildings, land and building improvements


•	Pipeline, gathering and other midstream projects


•	Further development of existing properties, acquisition of additional leasehold acreage, exploratory drilling and proceeds from the sale of certain assets at the exploration and production segment


•	Power generation and transmission opportunities, including certain costs for additional electric generating capacity


•	Environmental upgrades


•	The Company's proportionate share of Dakota Prairie Refinery at the pipeline and energy services segment


•	Other growth opportunities

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 2014 capital expenditures referred to previously. The Company expects the 2014 estimated capital expenditures to be funded by various sources, including internally generated funds; the Company's credit facilities, as described later; 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 later, contain restrictive covenants and cross-default provisions. In order to borrow under the respective credit agreements, the Company and its subsidiaries must be in compliance with the applicable covenants and certain other conditions, all of which the Company and its subsidiaries, as applicable, were in compliance with at June 30, 2014 . In the event the Company and its subsidiaries do not comply with the applicable covenants and other conditions, alternative sources of funding may need to be pursued. For more information on the covenants, certain other conditions and cross-default provisions, see Note 16 and Part II, Item 8 - Note 9, in the 2013 Annual Report.

The following table summarizes the outstanding revolving credit facilities of the Company and its subsidiaries at June 30, 2014 :



Company	Facility		Facility Limit			Amount Outstanding			Letters of Credit			Expiration Date
			(In millions)
MDU Resources Group, Inc.	Commercial paper/ Revolving credit agreement	(a)	$	175.0		$	79.0	(b)	$	—		5/8/19
Cascade Natural Gas Corporation	Revolving credit agreement		$	50.0	(c)	$	—		$	2.2	(d)	7/9/18
Intermountain Gas Company	Revolving credit agreement		$	65.0	(e)	$	—		$	—		7/13/18
Centennial Energy Holdings, Inc.	Commercial paper/ Revolving credit agreement	(f)	$	650.0		$	189.0	(b)	$	—		5/8/19

(a) The commercial paper program is supported by a revolving credit agreement with various banks (provisions allow for increased borrowings, at the option of the Company on stated conditions, up to a maximum of $225.0 million). There were no amounts outstanding under the credit agreement.

(b) Amount outstanding under commercial paper program.

(d) The outstanding letter of credit, as discussed in Note 21 , reduces the amount available under the credit agreement.

(e) Certain provisions allow for increased borrowings, up to a maximum of $90.0 million.

(f) The commercial paper program is supported by a revolving credit agreement with various banks (provisions allow for increased borrowings, at the option of Centennial on stated conditions, up to a maximum of $800.0 million). There were no amounts outstanding under the credit agreement.

The Company's and Centennial's respective commercial paper programs are supported by revolving credit agreements. While the amount of commercial paper outstanding does not reduce available capacity under the respective revolving credit agreements, the Company and Centennial do not issue commercial paper in an aggregate amount exceeding the available capacity under their credit agreements. The commercial paper borrowings may vary during the period, largely the result of fluctuations in working capital requirements due to the seasonality of the construction businesses.

The following includes information related to the preceding table.

MDU Resources Group, Inc. On May 8, 2014, the Company amended the revolving credit agreement to increase the borrowing limit to $175.0 million and extend the termination date to May 8, 2019. The Company's revolving credit agreement supports its commercial paper program. Commercial paper borrowings under this agreement are classified as long-term debt as they are intended to be refinanced on a long-term basis through continued commercial paper borrowings. The Company's objective is to maintain acceptable credit ratings in order to access the capital markets through the issuance of commercial paper. Downgrades in the Company's credit ratings have not limited, nor are currently expected to limit, the Company's ability

to access the capital markets. If the Company were to experience a downgrade of its credit ratings, it may need to borrow under its credit agreement and may experience an increase in overall interest rates with respect to its cost of borrowings.

Prior to the maturity of the credit agreement, the Company expects that it will negotiate the extension or replacement of this agreement. If the Company is unable to successfully negotiate an extension of, or replacement for, the credit agreement, or if the fees on this facility become too expensive, which the Company does not currently anticipate, the Company would seek alternative funding.

The Company's coverage of fixed charges including preferred stock dividends was 4.8 times for the 12 months ended June 30, 2014 and December 31, 2013 . Due to the $246.8 million after-tax noncash write-downs of oil and natural gas properties in 2012, earnings were insufficient by $19.8 million to cover fixed charges for the 12 months ended June 30, 2013 . If the $246.8 million after-tax noncash write-downs were excluded, the coverage of fixed charges including preferred stock dividends would have been 4.5 times for the 12 months ended June 30, 2013 .

The coverage of fixed charges including preferred stock dividends, that excludes the effect of the after-tax noncash write-downs of oil and natural gas properties is a non-GAAP financial measure. The Company believes that this non-GAAP financial measure is useful because the write-downs excluded are not indicative of the Company's cash flows available to meets its fixed charges obligations. The presentation of this additional information is not meant to be considered a substitute for the financial measure prepared in accordance with GAAP.

Total equity as a percent of total capitalization was 58 percent , 57 percent and 60 percent at June 30, 2014 and 2013 and December 31, 2013 , respectively. This ratio is calculated as the Company's total equity, divided by the Company's total capital. Total capital is the Company's total debt, including short-term borrowings and long-term debt due within one year, plus total equity. This ratio indicates how a company is financing its operations, as well as its financial strength.

On May 20, 2013, the Company entered into an Equity Distribution Agreement with Wells Fargo Securities, LLC with respect to the issuance and sale of up to 7.5 million shares of the Company's common stock. The common stock may be offered for sale, from time to time, in accordance with the terms and conditions of the agreement. Sales of such common stock may not be made after February 28, 2016. Proceeds from the shares of common stock under the agreement have been and are expected to be used for corporate development purposes and other general corporate purposes. Under the Equity Distribution Agreement, the Company issued 2.2 million shares of stock between April 1, 2014 and June 30, 2014, receiving net proceeds of $72.3 million , 3.7 million shares of stock between January 1, 2014 and June 30, 2014 , receiving net proceeds of $122.4 million and a total of 4.2 million shares of stock as of June 30, 2014 , receiving net proceeds of $137.0 million .

The Company currently has a shelf registration statement on file with the SEC, under which the Company may issue and sell any combination of common stock and debt securities. The Company may sell all or a portion of such securities if warranted by market conditions and the Company's capital requirements. Any public offer and sale of such securities will be made only by means of a prospectus meeting the requirements of the Securities Act and the rules and regulations thereunder. The Company's board of directors currently has authorized the issuance and sale of up to an aggregate of $1.0 billion worth of such securities. The Company's board of directors reviews this authorization on a periodic basis and the aggregate amount of securities authorized may be increased in the future.

The Company entered into a $150.0 million note purchase agreement on January 28, 2014. On April 15, 2014, the Company issued $50.0 million of Senior Notes with a due date of April 15, 2044, at an interest rate of 5.2 percent. The remaining $100.0 million of Senior Notes was issued on July 15, 2014, with due dates ranging from July 15, 2024 to July 15, 2026, at a weighted average interest rate of 4.3 percent.

Centennial Energy Holdings, Inc. On May 8, 2014, Centennial entered into an amended and restated revolving credit agreement which increased the borrowing limit to $650.0 million and extended the termination date to May 8, 2019. The credit agreement contains customary covenants and provisions, including a covenant of Centennial not to permit, as of the end of any fiscal quarter, the ratio of total consolidated debt to total consolidated capitalization to be greater than 65 percent. Other covenants include restrictions on the sale of certain assets, limitations on subsidiary indebtedness and the making of certain loans and investments.

Centennial's revolving credit agreement supports its commercial paper program. Commercial paper borrowings under this agreement are classified as long-term debt as they are intended to be refinanced on a long-term basis through continued commercial paper borrowings. Centennial's objective is to maintain acceptable credit ratings in order to access the capital markets through the issuance of commercial paper. Downgrades in Centennial's credit ratings have not limited, nor are currently expected to limit, Centennial's ability to access the capital markets. If Centennial were to experience a downgrade of its credit ratings, it may need to borrow under its credit agreement and may experience an increase in overall interest rates with respect to its cost of borrowings.

Prior to the maturity of the Centennial credit agreement, Centennial expects that it will negotiate the extension or replacement of this agreement, which provides credit support to access the capital markets. In the event Centennial is unable to successfully negotiate this agreement, or in the event the fees on this facility become too expensive, which Centennial does not currently anticipate, it would seek alternative funding.

Centennial entered into two separate two year $125.0 million term loan agreements with variable interest rates on March 31, 2014 and April 2, 2014, respectively. These agreements contain customary covenants and default provisions, including covenants not to permit, as of the end of any fiscal quarter, the ratio of Centennial's total debt to total capitalization to be greater than 65 percent. The covenants also include certain limitations on subsidiary indebtedness and restrictions on the sale of certain assets and on the making of certain loans and investments.

WBI Energy Transmission, Inc. WBI Energy Transmission has a $175.0 million amended and restated uncommitted long-term private shelf agreement with an expiration date of September 12, 2016. WBI Energy Transmission had $100.0 million of notes outstanding at June 30, 2014 , which reduced capacity under this uncommitted private shelf agreement.

Off balance sheet arrangements

In connection with the sale of the Brazilian Transmission Lines, Centennial has agreed to guarantee payment of any indemnity obligations of certain of the Company's indirect wholly owned subsidiaries who are the sellers in three purchase and sale agreements for periods ranging up to 10 years from the date of sale. The guarantees were required by the buyers as a condition to the sale of the Brazilian Transmission Lines. For more information, see Note 12 .

Centennial continues to guarantee CEM's obligations under a construction contract for an electric generating facility near Hobbs, New Mexico. For more information, see Note 21 .

Contractual obligations and commercial commitments

There are no material changes in the Company's contractual obligations relating to estimated interest payments, operating leases, purchase commitments, derivatives, asset retirement obligations, uncertain tax positions and minimum funding requirements for its defined benefit plans for 2014 from those reported in the 2013 Annual Report.

The Company's contractual obligations relating to long-term debt at June 30, 2014 , increased $332.5 million or 18 percent from December 31, 2013 . As of June 30, 2014 , the Company's contractual obligations related to long-term debt aggregated $2,187.1 million . The scheduled amounts of redemption (for the twelve months ended June 30, of each year listed) aggregate $42.2 million in 2015 ; $669.2 million in 2016 ; $116.0 million in 2017 ; $63.0 million in 2018 ; $382.4 million in 2019 ; and $914.3 million thereafter.

PART II -- OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

For information regarding legal proceedings, see Note 21 , which is incorporated herein by reference.

ITEM 1A. RISK FACTORS

This Form 10-Q contains forward-looking statements within the meaning of Section 21E of the Exchange Act. Forward-looking statements are all statements other than statements of historical fact, including without limitation those statements that are identified by the words "anticipates," "estimates," "expects," "intends," "plans," "predicts" and similar expressions.

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, also are 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.

There are no material changes in the Company's risk factors from those reported in Part I, Item 1A - Risk Factors in the 2013 Annual Report other than the risk related to environmental laws and regulations and the risk that the Company's operations could be adversely impacted by initiatives to reduce GHG emissions. 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.

Environmental and Regulatory Risks

The Company's operations are subject to 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 environmental laws and regulations affecting many aspects of its operations, including air quality, water quality, waste management and other environmental considerations. These laws and regulations can increase capital, operating and other costs, cause delays as a result of litigation and administrative proceedings, and create compliance, remediation, containment, monitoring and reporting obligations, particularly relating to electric generation operations and oil and natural gas development and processing. These laws and regulations generally require the Company to obtain and comply with a wide variety of environmental licenses, permits, inspections and other approvals. Although the Company strives to comply with all applicable environmental laws and regulations, public and private entities and private individuals may interpret the Company's legal or regulatory requirements differently and seek injunctive relief or other remedies against the Company. The Company cannot predict the outcome (financial or operational) of any such litigation or administrative proceedings.

Existing environmental laws and regulations may be revised and new laws and regulations seeking to protect the environment may be adopted or become applicable to the Company. These laws and regulations could require the Company to limit the use or output of certain facilities, restrict the use of certain fuels, install pollution controls, remediate environmental contamination, remove or reduce environmental hazards, or prevent or limit the development of resources. Revised or additional laws and regulations that increase compliance costs or restrict operations, particularly if costs are not fully recoverable from customers, could have a material adverse effect on the Company's results of operations and cash flows.

The EPA issued draft regulations that outline several possible approaches for coal combustion residuals management under the RCRA. One approach, designating coal ash as a hazardous waste, if adopted would significantly change the manner and increase the costs of managing coal ash at five plants that supply electricity to customers of Montana-Dakota. This designation

also could significantly increase costs for Knife River, which beneficially uses fly ash as a cement replacement in ready-mixed concrete and road base applications.

In December 2011, the EPA finalized the Mercury and Air Toxics Standards rules that will require reductions in mercury and other air emissions from coal- and oil-fired electric utility steam generating units. Montana-Dakota evaluated the pollution control technologies needed at its electric generation resources to comply with this rule and determined that the Lewis & Clark Station near Sidney, Montana, would require additional particulate matter control for non-mercury metal emissions. Montana-Dakota initially determined that the additional controls could be accomplished by installing a baghouse but later determined the baghouse is not currently an economically effective means of compliance. Montana-Dakota intends to comply with the rule by co-firing the plant with natural gas and lignite. Controls must be in place by April 16, 2015, or April 16, 2016, if a one-year extension is granted for completion of the pollution control project.

Hydraulic fracturing is an important common practice used by Fidelity that involves injecting water, sand, a water-thickening agent called guar, and trace amounts of chemicals, under pressure, into rock formations to stimulate oil, NGL and natural gas production. Fidelity follows state regulations for well drilling and completion, including regulations for hydraulic fracturing and recovered fluids disposal. Fracturing fluid constituents are reported on state or national websites. The EPA is developing a study to review potential effects of hydraulic fracturing on underground sources of drinking water; the results of that study could impact future legislation or regulation. The BLM has released draft well stimulation regulations for hydraulic fracturing operations. If implemented, the BLM regulations would affect only Fidelity's operations on BLM-administered lands. If adopted as proposed, the BLM regulations, along with other legislative initiatives and regulatory studies, proceedings or initiatives at federal or state agencies that focus on the hydraulic fracturing process, could result in additional compliance, reporting and disclosure requirements. Future legislation or regulation could increase compliance and operating costs, as well as delay or inhibit the Company's ability to develop its oil, NGL and natural gas reserves.

On August 16, 2012, the EPA published a final NSPS rule for the oil and natural gas industry. The NSPS rule phases in over two years. The first phase was effective October 15, 2012, and primarily covers natural gas wells that are hydraulically fractured. Under the new rule, gas vapors or emissions from the natural gas wells must be captured or combusted utilizing a high-efficiency device. Additional reporting requirements and control devices covering oil and natural gas production equipment will be phased in for certain new oil and gas facilities with a final effective date of January 1, 2015. This new rule's impacts on Fidelity, WBI Energy Transmission and WBI Energy Midstream are not expected to be material and are likely to include implementing recordkeeping, reporting and testing requirements and purchasing and installing required equipment.

Initiatives to reduce GHG emissions could adversely impact the Company's operations.

Concern that GHG emissions are contributing to global climate change has led to international, federal and state legislative and regulatory proposals to reduce or mitigate the effects of GHG emissions. On June 25, 2013, President Obama released his Climate Action Plan for the U.S. in which he stated his goal to reduce GHG emissions "in the range of 17 percent" below 2005 levels by 2020. The president issued a memorandum to the EPA on the same day, instructing the EPA to re-propose the GHG NSPS rule for new electric generation units. The EPA released the re-proposed rule on January 8, 2014, in the Federal Register, which takes the place of the rule proposed in 2012 for new electric generation units that the EPA did not finalize. This rule applies to new fossil fuel-fired electric generation units, including coal-fired units, natural gas-fired combined-cycle units and natural gas-fired simple-cycle peaking units. The EPA's 1,100 pounds of carbon dioxide per MW hour emissions standard for coal-fired units does not allow any new coal-fired electric generation to be constructed unless carbon dioxide is captured and sequestered.

President Obama also directed the EPA to develop a GHG NSPS standard for existing fossil fuel-fired electric generation units by June 1, 2014, with finalization by June 1, 2015. On June 18, 2014, the EPA published in the Federal Register a proposed rule limiting carbon dioxide emissions from existing fossil fuel-fired electric generating units and a separate proposed rule limiting carbon dioxide emissions from existing units that are modified or reconstructed.

In the existing source rule, the EPA requires carbon dioxide emission reductions from each state and instructs each state, or group of states that work together, to submit a plan to the EPA by June 30, 2016, that demonstrates how the state will achieve the targeted emission reductions by 2030. The state plans could include performance standards, emissions reductions or limits on generation for each existing fossil fuel-fired generating unit. It is unknown at this time what each state will require for emissions reductions from each Montana-Dakota owned and jointly owned fossil fuel-fired electric generating unit. In the EPA’s proposed GHG rule for modified or reconstructed fossil fuel-fired sources, the EPA proposes emissions limits that could potentially be unachievable. Montana-Dakota does not plan to modify or reconstruct any fossil fuel-fired units at this time, but may modify or reconstruct units in the future which must comply with the rule limitations.

The Company’s primary GHG emission is carbon dioxide from fossil fuels combustion at Montana-Dakota's electric generating facilities, particularly its coal-fired facilities. Approximately 70 percent of Montana-Dakota's owned generating capacity and more than 90 percent of the electricity it generates is from coal-fired facilities.

There may also be new treaties, legislation or regulations to reduce GHG emissions that could affect Montana-Dakota's electric utility operations by requiring additional energy conservation efforts or renewable energy sources, as well as other mandates that could significantly increase capital expenditures and operating costs. If Montana-Dakota does not receive timely and full recovery of GHG emission compliance costs from its customers, then such costs could adversely impact the results of its operations.

In addition to Montana-Dakota's electric generation operations, the GHG emissions from the Company's other operations are monitored, analyzed and reported as required by applicable laws and regulations. The Company monitors GHG regulations and the potential for GHG regulations to impact operations.

Due to the uncertain availability of technologies to control GHG emissions and the unknown obligations that potential GHG emission legislation or regulations may create, the Company cannot determine the potential financial impact on its operations.

Exhibit B-1

Opinion of Paul K. Sandness

May 8, 2014

Wells Fargo Bank, National Association

as Administrative Agent and as a Lender,

and the Other Financial Institutions Listed on

Schedule A Hereto

Ladies and Gentlemen:

I am the General Counsel of MDU Resources Group, Inc., a Delaware corporation (the “Company” ), and in such capacity, I am familiar with the negotiation, preparation, execution and delivery of (i) a Second Amendment to Credit Agreement (the “Amendment” ) dated May 8, 2014 among the Company, Wells Fargo Bank, National Association, as Administrative Agent and as a Lender, and The Bank of Tokyo-Mitsubishi UFJ, Ltd., PNC Bank, National Association, U.S. Bank National Association and KeyBank National Association, as Lenders, (ii) a Fee Letter (the “Wells Fargo Fee Letter” ) dated May 2, 2014 among Wells Fargo Securities, LLC, Wells Fargo Bank, National Association, as Administrative Agent, and the Company, setting forth certain fees to be paid in connection with the Amendment, and (iii) a Fee Letter (together with the Amendment and the Wells Fargo Fee Letter, the “Amendment Documents” ) dated May 2, 2014 between The Bank of Tokyo-Mitsubishi UFJ, Ltd. and the Company, setting forth certain fees to be paid in connection with the Amendment. This opinion is furnished to you pursuant to Section 6(d) of the Amendment and at the instruction of the Company. All capitalized terms used but not otherwise defined herein have the meanings ascribed thereto in or pursuant to the Amendment.

For the purpose of rendering the opinions contained herein, I have examined and reviewed the Amendment Documents and the Loan Documents. I have also examined the originals, or copies certified to my satisfaction, of the Restated Certificate of Incorporation and By-Laws of the Company, resolutions adopted by the Board of Directors of the Company authorizing the execution, delivery and performance by the Company of the Amendment Documents and the Loan Documents, and such other corporate records of the Company and agreements, instruments and other documents as I have deemed necessary as a basis for the opinions expressed below. In my examination, I have assumed the genuineness of all signatures, other than the signatures of the Company on the Amendment Documents and the Loan Documents, the legal capacity of natural persons, the authenticity of all documents submitted to me as originals and the conformity with original documents of all documents submitted to me as certified or photostatic copies. I have also assumed, with your consent, the due execution and delivery, pursuant to due authorization, of the Amendment Documents and the Loan Documents by all parties thereto other than the Company and the validity and binding effect of the Amendment Documents and the Loan Documents upon such parties.

As to any facts that I did not independently establish or verify, I have relied without independent investigation upon statements, representations and certificates of officers of the Company and as to the matters addressed therein, upon certificates or communications from public officials. As used herein, the phrase “to my knowledge” with respect to the existence or absence of facts is intended to signify that, while I have made no specific inquiry or other independent examination to determine the existence or absence of such facts, no factual information has come to my attention which causes me to believe that such facts are not accurate.

Based on and subject to the foregoing and upon such investigation as I have deemed necessary, and subject to the qualifications set forth below, it is my opinion that:

1. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of Delaware.

2. The Company is duly qualified as a foreign corporation to transact business and is in good standing in Minnesota, Montana, North Dakota and South Dakota, and is not required, whether by reason of ownership or leasing of property or the conduct of its business, to be qualified in any other jurisdiction, except where the failure so to qualify or to be in good standing would not result in a Material Adverse Effect.

3. The Company has the corporate power and authority to execute and deliver the Amendment Documents and to perform its obligations under the Amendment Documents and under the Loan Documents as amended thereby, and has all requisite corporate power and authority, licenses and permits to own its assets and to carry on its business as currently conducted and as contemplated to be conducted by the Amendment and by the Credit Agreement as amended thereby.

4. The execution and delivery of the Amendment Documents, and the performance by the Company of the Amendment Documents and the Loan Documents as amended thereby, have been duly authorized by all necessary corporate action and by all necessary public utility commissions and other regulatory bodies having jurisdiction over the Company (except as noted in Schedule 4.2 of the Credit Agreement with respect to Borrowings made after September 12, 2015), and each of the Amendment Documents has been duly executed and delivered by the Company.

5. The execution and delivery of the Amendment Documents, and the performance by the Company of the Amendment Documents and the Loan Documents as amended thereby, do not and will not (a) require any consent or approval of the stockholders of the Company or any authorization, consent or approval by any governmental department, commission, board, bureau, agency or instrumentality, other than Authorizing Orders set forth in Schedule 4.2 to the Credit Agreement that (except as noted therein with respect to Borrowings made after September 12, 2015) have been obtained and are in full force and effect, (b) violate any provision of any law, rule or regulation or any order, writ, injunction or decree presently in effect having applicability to the Company or the Restated Certificate of Incorporation or By-Laws of the Company, (c) 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 Company is a party or by which its properties may be bound or affected, or (d) except as provided therein, result in, or require, the creation or imposition of any Lien or other charge or encumbrance of any nature upon or with respect to any of its properties.

Except as set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013, or in any document subsequently filed by the Company pursuant to Section 13, 14 or 15(d) of the Exchange Act, there are no actions, suits or proceedings pending or, to my knowledge, threatened against or affecting the Company or the properties of the Company before any court or governmental department, commission, board, bureau, agency or instrumentality, which, if determined adversely to the Company, would have a Material Adverse Effect.

Opinion of Cohen Tauber Spievack & Wagner P.C.

May 8, 2014

Wells Fargo Bank, National Association, as

Administrative Agent and as a Lender,

and the Other Financial Institutions Listed on

Schedule A Hereto

Ladies and Gentlemen:

We have acted as special counsel for MDU Resources Group, Inc., a Delaware corporation (the “Company” ), in connection with (i) a Second Amendment to Credit Agreement (the “Amendment” ) dated May 8, 2014 among the Company, Wells Fargo Bank, National Association, as Administrative Agent and as a Lender, and The Bank of Tokyo-Mitsubishi UFJ, Ltd., PNC Bank, National Association, U.S. Bank National Association and KeyBank National Association, as Lenders, (ii) a Fee Letter (the “Wells Fargo Fee Letter” ) dated May 2, 2014 among Wells Fargo Securities, LLC, Wells Fargo Bank, National Association, as Administrative Agent, and the Company, setting forth certain fees to be paid in connection with the Amendment, and (iii) a Fee Letter (together with the Amendment and the Wells Fargo Fee Letter, the “Amendment Documents” ) dated May 2, 2014 between The Bank of Tokyo-Mitsubishi UFJ, Ltd. and the Company, setting forth certain fees to be paid in connection with the Amendment. This opinion is furnished to you pursuant to Section 6(d) of the Amendment and at the instruction of the Company. All capitalized terms used but not otherwise defined herein have the meanings ascribed thereto in or pursuant to the Amendment.

For the purpose of rendering the opinions contained herein, we have examined and reviewed the Amendment Documents and the Loan Documents. We have also examined the originals, or copies certified to our satisfaction, of the Restated Certificate of Incorporation and By-Laws of the Company, resolutions adopted by the Board of Directors of the Company authorizing the execution, delivery and performance by the Company of the Amendment Documents and the Loan Documents, and such other corporate records of the Company and agreements, instruments and other documents as we have deemed necessary as a basis for the opinions expressed below. In our examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals and the conformity with original documents of all documents submitted to us as certified or photostatic copies. We have also assumed, with your consent, the due execution and delivery, pursuant to due authorization, of the Amendment Documents and the Loan Documents by all parties thereto other than the Company and the validity and binding effect of the Amendment Documents and the Loan Documents upon such parties. As to any facts that we did not independently establish or verify, we have relied without independent investigation upon statements, representations and certificates of officers of the Company and as to the matters addressed therein, upon certificates or communications from public officials.

Based on and subject to the foregoing and upon such investigation as we have deemed necessary, and subject to the qualifications set forth below, it is our opinion that:

1. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of Delaware.

2. The Company has the corporate power and authority to execute and deliver the Amendment Documents and to perform its obligations under the Amendment Documents and under the Loan Documents as amended thereby.

3. The execution and delivery of the Amendment Documents, and the performance by the Company of the Amendment Documents and the Loan Documents as amended thereby, have been duly authorized by all necessary corporate action, and each of the Amendment Documents has been duly executed and delivered by the Company.

4. The execution and delivery of the Amendment Documents, and the performance by the Company of the Amendment Documents and the Loan Documents as amended thereby, do not and will not (a) require any consent or approval of the stockholders of the Company or any authorization, consent or approval by any governmental department, commission, board, bureau, agency or instrumentality, other than Authorizing Orders set forth in Schedule 4.2 to the Credit Agreement that (except as noted therein with respect to Borrowings made after September 12, 2015) have been obtained and are in full force and effect, or (b) violate any provision of any law, rule or regulation or any order, writ, injunction or decree presently in effect having applicability to the Company or the Restated Certificate of Incorporation or By-Laws of the Company.

5. Each of the Amendment Documents and each of the Loan Documents as amended thereby constitutes a legal, valid and binding obligation of the Company enforceable in accordance with its respective terms, subject to the effect of any applicable bankruptcy, insolvency, moratorium or other similar laws affecting creditors’ rights generally and of general principles of equity (regardless of whether applied in a proceeding in equity or at law), except that we express no opinion as to (a) Section 7.3 of the Credit Agreement, (b) the enforceability of rights to indemnify under federal or state securities laws, or (c) the enforceability of waivers of the parties of their respective rights and remedies under law.

This opinion is limited to the laws of the State of New York, the General Corporation Law of the State of Delaware, and the federal laws of the United States of America. We express no opinion as to the laws of any other jurisdiction.

In rendering this opinion, we have relied as to all matters of North Dakota law, as to matters addressed therein, with your consent, upon the opinion of Paul K. Sandness, Bismarck, North Dakota, the General Counsel of the Company.

This opinion is intended solely for your use and is rendered solely in connection with the Amendment Documents and the Loan Documents, and without our written consent may not be (a) relied upon by you for any other purpose, or (b) relied upon by any other person or entity for any purpose, except that Paul K. Sandness may rely on the opinions expressed herein in rendering to you his opinion of even date herewith.

The opinions expressed above are limited to the law and facts in effect on the date hereof. We disclaim any obligation to advise you of facts, circumstances, events or developments which hereafter may be brought to our attention and which might alter, affect or modify the opinions expressed herein.

We hereby consent to reliance by the Administrative Agent and the Lenders now or hereafter parties to the Agreement on the opinions expressed herein.

Very truly yours,

In the event of any conflict between the accounts and records maintained by any Bank and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Bank made through the Administrative Agent, the Company shall execute and deliver to such Bank (through the Administrative Agent) a Note, which shall evidence such Bank’s Loans in addition to such accounts or records. Each Bank may attach schedules to its Note and endorse thereon the date, Type (if applicable), amount and maturity of its Loans and payments with respect thereto. The Company hereby authorizes the Banks and the Administrative Agent to extend, convert or continue Advances, effect selections of Rate Options and transfer funds based on telephonic notices made by any person or persons the Administrative Agent or any Bank in good faith believes to be acting on behalf of the Company. The Company agrees to deliver promptly to the Administrative Agent a written confirmation, if such confirmation is requested by the Administrative Agent or any Bank, of each telephonic notice signed by a Responsible Officer. If the written confirmation differs in any material respect from the action taken by the Administrative Agent and the Banks, the records of the Administrative Agent and the Banks shall govern absent manifest error.

If any payment of principal of or interest on an Advance shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a principal payment, such extension of time shall be included in computing interest in connection with such payment.

The Administrative Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If such Bank or the Company, as the case may be, has not in fact made such payment to the Administrative Agent, the recipient of such payment shall, on demand by the Administrative Agent, repay to the Administrative Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Administrative Agent until the date the Administrative Agent recovers such amount at a rate per annum equal to (i) in the case of payment by a Bank, the Federal Funds Effective Rate for such day or (ii) in the case of payment by the Company, the interest rate applicable to the relevant Loan.

709152408 03173762

be only to determine that the documents delivered under each applicable Letter of Credit in connection with a demand for payment are in conformity in all material respects with such Letter of Credit.

The Company shall be irrevocably and unconditionally obligated to reimburse each Issuer on or before the applicable Honor Date for any amount to be paid by such Issuer upon any drawing under any Letter of Credit, without presentment, demand, protest or other formalities of any kind; provided that the Company shall not be precluded from asserting any claim for direct (but not consequential) damages suffered by the Company to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence of such Issuer in determining whether a request presented under any Letter of Credit complied with the terms of such Letter of Credit or (ii) such Issuer’s failure to pay under any Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of such Letter of Credit.

709152408 03173762

setoff, counterclaim or defense to payment which the Company may have or have had against the applicable Issuer, any Bank or any beneficiary of a Letter of Credit. The Company further agrees with each Issuer and the Banks that no Issuer or Bank shall be responsible for, and the Company’s Reimbursement Obligation in respect of any Letter of Credit shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or among the Company, any of its Affiliates, the beneficiary of any Letter of Credit or any financing institution or other party to whom any Letter of Credit may be transferred or any claims or defenses whatsoever of the Company or of any of its Affiliates against the beneficiary of any Letter of Credit or any such transferee.

Each Issuer shall be fully justified in failing or refusing to take any action under this Agreement unless it shall first have received such advice or concurrence of the Majority Banks as it reasonably deems appropriate or it shall first be indemnified to its reasonable satisfaction by the Banks against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Notwithstanding any other provision of this Section 2.16 , each Issuer shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement in accordance with a request of the Majority Banks, and such request and any action taken or failure to act pursuant thereto shall be binding upon the Banks and any future holder of a participation in any applicable Letter of Credit.

(i) Indemnification . The Company agrees to indemnify and hold harmless each Bank, the applicable Issuer and the Administrative Agent, and their respective directors, officers, agents and employees, from and against any and all claims and damages, losses, liabilities, costs or expenses which such Bank, such Issuer or the Administrative Agent may incur (or which may be claimed against such Bank, such Issuer or the Administrative Agent by any Person whatsoever) by reason of or in connection with the issuance, execution and delivery or transfer of or payment or failure to pay under any Letter of Credit or any actual or proposed use of any Letter of Credit, including any claims, damages, losses, liabilities, costs or expenses which such Issuer may incur by reason of or in connection with (i) the failure of any other Bank to fulfill or comply with its obligations to such Issuer hereunder (but nothing herein contained shall affect any right the Company may have against any defaulting Bank) or (ii) by reason of or on account of such Issuer issuing any Letter of Credit which specifies that the term “Beneficiary” therein includes any successor by operation of law of the named Beneficiary, but which Letter of Credit does not require that any drawing by any such successor Beneficiary be accompanied by a

709152408 03173762

copy of a legal document, satisfactory to such Issuer, evidencing the appointment of such successor Beneficiary; provided that the Company shall not be required to indemnify any Bank, the applicable Issuer or the Administrative Agent for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by (x) the willful misconduct or gross negligence of such Issuer in determining whether a request presented under any Letter of Credit issued by such Issuer complied with the terms of such Letter of Credit or (y) such Issuer’s failure to pay under any Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of such Letter of Credit. Nothing in this Section 2.16(i) is intended to limit the obligations of the Company under any other provision of this Agreement.

(j) Banks’ Indemnification . Each Bank shall, ratably in accordance with its Pro Rata Share, indemnify each applicable Issuer and its affiliates and their respective directors, officers, agents and employees (to the extent not reimbursed by the Company) against any cost, expense (including reasonable counsel fees and charges), claim, demand, action, loss or liability (except such as result from such indemnitees’ gross negligence or willful misconduct or such Issuer’s failure to pay under any Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of such Letter of Credit) that such indemnitees may suffer or incur in connection with this Section 2.16 or any action taken or omitted by such indemnitees hereunder.

If the Company, the Administrative Agent and each Issuer agree in writing that a Bank is no longer a Defaulting Bank, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions agreed to by the Company, the Administrative Agent, each Issuer and such Bank set forth in such notice, such Bank will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Banks or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit to be held pro rata by the Banks in accordance with the Commitments under the applicable Facility (without giving effect to Section 2.18(a)(iv) ) whereupon such Bank will cease to be a Defaulting Bank; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Company while that Bank was a Defaulting Bank; and provided , further , that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Bank to

709152408 03173762

Bank will constitute a waiver or release of any claim of any party hereunder arising from that Bank’s having been a Defaulting Bank.

(c) New Letters of Credit . So long as any Bank is a Defaulting Bank, no Issuer shall be required to issue, extend, renew or increase any Letter of Credit unless it is satisfied that it will have no Fronting Exposure after giving effect thereto.

ARTICLE III

YIELD PROTECTION; TAXES

3.01 Increased Costs Generally . If, on or after the date of this Agreement, there occurs any adoption of or change in any law, governmental or quasi-governmental rule, regulation, policy, guideline, interpretation, or directive (whether or not having the force of law) or in the interpretation, promulgation, implementation or administration thereof by any governmental or quasi-governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, including, notwithstanding the foregoing, all requests, rules, guidelines or directives (x) in connection with the Dodd-Frank Wall Street Reform and Consumer Protection Act or (y) promulgated by the Bank for International Settlements, the Basel Committee on Banking Regulations and Supervisory Practices (or any successor or similar authority) or the United States financial regulatory authorities, in each case of clauses (x) and (y), regardless of the date enacted, adopted, issued, promulgated or implemented, or compliance by any Bank or applicable Lending Installation or any Issuer with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency (any of the foregoing, a “ Change in Law ”) which:

(a) subjects any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto, or

(b) imposes or increases or deems applicable any reserve, assessment, insurance charge, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Bank or any applicable Lending Installation or any Issuer (other than reserves and assessments taken into account in determining the Eurodollar Rate), or

(c) imposes any other condition (other than Taxes) the result of which is to increase the cost to any Bank or any applicable Lending Installation or any Issuer of funding or maintaining its Eurodollar Loans, or of issuing or participating in Letters of Credit, or reduces any amount receivable by any Bank or any applicable Lending Installation or any Issuer in connection with its Eurodollar Loans, Letters of Credit or participations therein, or requires any Bank or any applicable Lending Installation or any Issuer to make any payment calculated by reference to the amount of Eurodollar Loans, Letters of Credit or participations therein held or interest or Letter of Credit Fees received by it, by an amount deemed material by such Bank or such Issuer as the case may be,

and the result of any of the foregoing is to increase the cost to such Person of making or maintaining its Loans or Commitment or of issuing or participating in Letters of Credit or to reduce the return received by such Person in connection with such Loans or Commitment, Letters of Credit or participations therein, then, within 15 days after demand by such Person, the

709152408 03173762

Company shall pay such Person, as the case may be, such additional amount or amounts as will compensate such Person for such increased cost or reduction in amount received .

3.02 Changes in Capital Adequacy Regulations . If any Bank or Issuer determines that any Change in Law affecting such Bank or Issuer or any lending office of such Bank or such Bank’s or Issuer’s holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing the rate of return on such Bank’s or Issuer’s capital or on the capital of such Bank’s or Issuer’s holding company, if any, as a consequence of this Agreement, the Commitment of such Bank or the Loans made by, or participations in Letters of Credit held by, such Bank, or the Letters of Credit issued by any Issuer, to a level below that which such Bank or Issuer or such Bank’s or Issuer’s holding company could have achieved but for such Change in Law (taking into consideration such Bank’s or Issuer’s policies and the policies of such Bank’s or Issuer’s holding company with respect to capital adequacy), then from time to time the Company will pay to such Bank or Issuer, as the case may be, such additional amount or amounts as will compensate such Bank or Issuer or such Bank’s or Issuer’s holding company for any such reduction suffered.

3.03 Certificates for Reimbursement; Delay in Requests .

(a) A certificate of a Bank or Issuer setting forth the amount or amounts necessary to compensate such Bank or Issuer or its holding company, as the case may be, as specified in Section 3.01 or 3.02 and delivered to the Company, shall be conclusive absent manifest error. The Company shall pay such Bank or Issuer, as the case may be, the amount shown as due on any such certificate within 15 days after receipt thereof.

(b) Failure or delay on the part of any Bank or Issuer to demand compensation pursuant to this Section shall not constitute a waiver of such Bank’s or Issuer’s right to demand such compensation; provided that the Company shall not be required to compensate a Bank or Issuer pursuant to this Section for any increased costs incurred or reductions suffered more than 180 days prior to the date that such Bank or Issuer, as the case may be, notifies the Company of the Change in Law giving rise to such increased costs or reductions, and of such Bank’s or Issuer’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180 day period referred to above shall be extended to include the period of retroactive effect thereof).

3.04 Availability of Types of Advances . If (a) any Bank determines that the making, maintaining or funding of its Eurodollar Loans at a suitable Lending Installation would violate any applicable law, rule, regulation, or directive, whether or not having the force of law, or (b) if the Majority Banks determine that (i) deposits of a type and maturity appropriate to match fund Eurodollar Advances are not available or (ii) the interest rate applicable to Eurodollar Advances does not accurately reflect the cost of making or maintaining Eurodollar Advances, then the Administrative Agent shall suspend the availability of Eurodollar Advances and, in the case of clause (a) only, require any affected Eurodollar Advances to be repaid or converted to Base Rate Advances, subject to the payment of any funding indemnification amounts required by Section 3.05 .

3.05 Funding Indemnification . If (a) any payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, (b) a Eurodollar Advance is not made on the date

709152408 03173762

specified by the Company for any reason other than default by the Banks, (c) a Eurodollar Loan is converted other than on the last day of the Interest Period applicable thereto, (d) the Company fails to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto or (e) any Eurodollar Loan is assigned other than on the last day of the Interest Period applicable thereto as a result of a request by the Company pursuant to Section 2.15 , the Company will indemnify each Bank for any costs, expenses and Interest Differential (as determined by such Bank) incurred as a result thereof. The term “Interest Differential” shall mean that sum equal to the greater of zero or the financial loss incurred by the applicable Bank resulting from any action described in clauses (a) through (e) above, calculated as the difference between the amount of interest such Bank would have earned (from the investments in money markets as of the Borrowing Date of such Loan) had such action not occurred and the interest such Bank will actually earn (from like investments in money markets as of the date of prepayment) as a result of the redeployment of such funds. Because of the short-term nature of this facility, the Company agrees that Interest Differential shall not be discounted to its present value.

3.06 Taxes .

(a) Issuer . For purposes of this Section 3.06 , the term “Bank” includes any Issuer.

(b) Payments Free of Taxes . Any and all payments by or on account of any obligation of the Company under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the Company shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(c) Payment of Other Taxes by the Company . The Company shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes.

(d) Indemnification by the Company . The Company shall indemnify each Recipient, within 10 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Company by a Bank (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Bank, shall be conclusive absent manifest error.

709152408 03173762

(e) Indemnification by the Banks . Each Bank shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Bank (but only to the extent that the Company has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Company to do so) and (ii) any Excluded Taxes attributable to such Bank, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Bank by the Administrative Agent shall be conclusive absent manifest error. Each Bank hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Bank under any Loan Document or otherwise payable by the Administrative Agent to such Bank from any other source against any amount due to the Administrative Agent under this clause (e) .

(f) Evidence of Payments . As soon as practicable after any payment of Taxes by the Company to a Governmental Authority pursuant to this Section 3.06 , the Company shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(g) Status of Banks .

(i) Any Bank that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Company and the Administrative Agent, at the time or times reasonably requested by the Company or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Company or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Bank, if reasonably requested by the Company or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Company or the Administrative Agent as will enable the Company or the Administrative Agent to determine whether or not such Bank is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 3.06(g)(ii)(A) , (ii)(B) and (ii)(D) below) shall not be required if in the applicable Bank’s reasonable judgment such completion, execution or submission would subject such Bank to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Bank.

(ii) Without limiting the generality of the foregoing,

(A) any Bank that is a U.S. Person shall deliver to the Company and the Administrative Agent on or prior to the date on which such Bank becomes a Bank under this Agreement (and from time to time thereafter upon the reasonable request of the Company or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Bank is exempt from U.S. federal backup withholding tax;

709152408 03173762

(B) any Foreign Bank shall, to the extent it is legally entitled to do so, deliver to the Company and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Bank becomes a Bank under this Agreement (and from time to time thereafter upon the reasonable request of the Company or the Administrative Agent), whichever of the following is applicable:

(1) in the case of a Foreign Bank claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(2) executed originals of IRS Form W-8ECI;

(3) in the case of a Foreign Bank claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit E-1 to the effect that such Foreign Bank is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Company within the meaning of Section 871(h)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “ U.S. Tax Compliance Certificate ”) and (y) executed originals of IRS Form W-8BEN; or

(4) to the extent a Foreign Bank is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit E-2 or Exhibit E-3 , IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Bank is a partnership and one or more direct or indirect partners of such Foreign Bank are claiming the portfolio interest exemption, such Foreign Bank may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit E-4 on behalf of each such direct and indirect partner;

(C) any Foreign Bank shall, to the extent it is legally entitled to do so, deliver to the Company and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Bank becomes a Bank under this Agreement (and from time to time thereafter upon the reasonable request of the Company or the Administrative Agent), executed originals of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Company or the Administrative Agent to determine the withholding or deduction required to be made; and

(D) if a payment made to a Bank under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Bank were to fail to comply with the applicable reporting requirements of FATCA (including those contained

709152408 03173762

in Section 1471(b) or 1472(b) of the Code, as applicable), such Bank shall deliver to the Company and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Company or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Company or the Administrative Agent as may be necessary for the Company and the Administrative Agent to comply with their obligations under FATCA and to determine that such Bank has complied with such Bank’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Each Bank agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Company and the Administrative Agent in writing of its legal inability to do so.

(h) Treatment of Certain Refunds . If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 3.06 (including by the payment of additional amounts pursuant to this Section 3.06 ), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this clause (h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this clause (h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this clause (h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This clause shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

3.07 Mitigation Obligations; Replacement of Banks .

(a) Mitigation Obligations . If any Bank requests compensation under Section 3.01 or 3.02 , or requires the Company to pay any Indemnified Taxes or additional amounts to any Bank or any Governmental Authority for the account of any Bank pursuant to Section 3.06 , then such Bank shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Bank, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.01 , 3.02 or 3.06 , as the case may be, in the future, and (ii) would not subject such Bank to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Bank. The Company hereby

709152408 03173762

agrees to pay all reasonable costs and expenses incurred by any Bank in connection with any such designation or assignment.

(b) Replacement of Banks . If any Bank requests compensation under Section 3.01 or 3.02 , or requires the Company to pay any Indemnified Taxes or additional amounts to any Bank or any Governmental Authority for the account of any Bank pursuant to Section 3.06 , and, in each case, such Bank has declined or is unable to designate a different lending office in accordance with Section 3.07(a) (each such Bank, an “ Increased Cost Bank ”), or if any Bank is a Defaulting Bank or a Non-Consenting Bank, then the Company may, at its sole expense and effort, upon notice to such Bank and the Administrative Agent, require such Bank to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 10.08 ), all of its interests, rights (other than its existing rights to payments pursuant to Section 3.01 , 3.02 or 3.06 ) and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Bank, if a Bank accepts such assignment); provided that:

(A) the Company shall have paid to the Administrative Agent the assignment fee (if any) specified in Section 10.08 ;

(B) such Bank shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 3.05 ) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Company (in the case of all other amounts);

(C) in the case of any such assignment resulting from a claim for compensation under Section 3.01 or 3.02 , such assignment will result in a reduction in such compensation or payments thereafter;

(D) such assignment does not conflict with applicable law; and

(E) in the case of any assignment resulting from a Bank becoming a Non-Consenting Bank, the applicable assignee shall have consented to the applicable amendment, waiver or consent.

(c) A Bank shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Bank or otherwise, the circumstances entitling the Company to require such assignment and delegation cease to apply. Each Bank and Issuer hereby grants to the Administrative Agent an irrevocable power of attorney (which power is coupled with an interest) to execute and deliver, on behalf of such Bank or Issuer, as the case may be, as assignor, any Assignment Agreement necessary to effect any assignment of such Bank’s or Issuer’s interests hereunder in the circumstances contemplated by this Section 3.07 . Each Bank agrees that if the Company exercises its option hereunder to cause an assignment by such Bank as an Increased Cost Bank, Non-Consenting Bank or Defaulting Bank, such Bank shall, promptly after receipt of written notice of such election, execute and deliver all documentation necessary to effect such assignment in accordance with Section 3.07 . In the event that a Bank does not comply with the requirements of the immediately preceding sentence within one Business Day after receipt of such notice, each Bank hereby authorizes and directs the

709152408 03173762

Administrative Agent to execute and deliver such documentation as may be required to give effect to an assignment in accordance with Section 10.08 on behalf of an Increased Cost Bank, Non-Consenting Bank or Defaulting Bank and any such documentation so executed by the Administrative Agent shall be effective for purposes of documenting an assignment pursuant to Section 10.08 .

5.05 Litigation; Environmental Claims . Except as set forth in the Company’s financial statements dated December 31, 2013, there are, as of the Execution Date, no actions, suits, proceedings, claims (including Environmental Claims) or disputes pending, or, to the knowledge of the Company, threatened, at law, in equity, in arbitration or by or before any Governmental Authority, against the Company, or its Subsidiaries or any of their respective properties which: (a) purport to affect or pertain to this Agreement or any other Loan Document, or any of the transactions contemplated hereby or thereby; or (b) if determined adversely to the Company or its Subsidiaries, would reasonably be expected to have a Material Adverse Effect.

Any assignee of the rights to any Loan or any Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the owner of the rights to any Loan (whether or not a Note has been issued in evidence thereof), shall be conclusive and binding on any subsequent holder or assignee of the rights to such Loan.

709152408 03173762

owing to such Bank, any Note held by such Bank, the Commitment of such Bank or any other interest of such Bank under the Loan Documents. Upon any such sale by a Bank of participating interests to a Participant, such Bank’s obligations under the Loan Documents shall remain unchanged, such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, such Bank shall remain the owner of its Loans and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents, all amounts payable by the Company under this Agreement shall be determined as if such Bank had not sold such participating interests, and the Company and the Administrative Agent shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under the Loan Documents.

(b) Voting Rights . Each Bank shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than any amendment, modification or waiver which requires the unanimous consent of all Banks under Section 10.01 .

(c) Benefit of Setoff . The Company agrees that each Participant shall be deemed to have the right of setoff provided in Section 10.10 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its participating interest were owing directly to it as a Bank under the Loan Documents; provided that each Bank shall retain the right of setoff provided in Section 10.10 with respect to the amount of participating interests sold to each Participant. The Banks agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 10.10 , agrees to share with each Bank, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 10.10 as if each Participant were a Bank.

(d) Permitted Assignments . Any Bank may, in the ordinary course of its business and in accordance with applicable law, at any time assign to one or more Eligible Assignees (“ Purchasers ”) all or any part of its rights and obligations under the Loan Documents. Any assignment shall be made pursuant to a document substantially in the form of Exhibit F or in such other form as may be agreed to by the parties thereto. The consent of the Company and the Administrative Agent (in each case not to be unreasonably withheld or delayed) shall be required prior to an assignment becoming effective with respect to a Purchaser which is not a Bank or an Affiliate thereof; provided that if a Default or an Event of Default has occurred and is continuing, the consent of the Company shall not be required. The consent of each Issuer (not to be unreasonably withheld or delayed) shall be required prior to an assignment becoming effective unless the applicable Purchaser is a Bank. Each such assignment with respect to a Purchaser which is not a Bank or an Affiliate thereof shall (unless each of the Company and the Administrative Agent otherwise consents) be in an amount not less than the lesser of (i) $5,000,000 or (ii) the remaining amount of the assigning Bank’s Commitment (calculated as at the date of such assignment) or outstanding Loans (if such Commitment has been terminated).

(e) Effect; Effective Date . Upon (i) delivery to the Administrative Agent of a notice of assignment, substantially in the form attached as Annex I to Exhibit F (a “ Notice of Assignment ”), together with any consents required by Section 10.08(d) , and (ii) payment by the assigning Bank of a $4,000 fee to the Administrative Agent for processing such assignment, such assignment shall become effective on the effective date specified in such Notice of Assignment. The Notice of Assignment shall contain a representation by the Purchaser to the effect that none

709152408 03173762

of the consideration used to make the purchase of the Commitment and Loans under the applicable assignment agreement constitutes “plan assets” as defined under ERISA and that the rights and interests of the Purchaser in and under the Loan Documents will not be “plan assets” under ERISA. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Bank party to this Agreement and any other Loan Document executed by or on behalf of the Banks and shall have all the rights and obligations of a Bank under the Loan Documents, to the same extent as if it were an original party hereto, and no further consent or action by the Company, the Banks or the Administrative Agent shall be required to release the transferor Bank with respect to the percentage of the Aggregate Commitment and Loans assigned to such Purchaser; provided that, except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Bank will constitute a waiver or release of any claim of any party hereunder arising from that Bank’s having been a Defaulting Bank. Upon the consummation of any assignment to a Purchaser pursuant to this Section 10.08(e) , the transferor Bank, the Administrative Agent and the Company shall, if the transferor Bank or the Purchaser desires that its Loans be evidenced by Notes, make appropriate arrangements so that new Notes or, as appropriate, replacement Notes are issued to such transferor Bank and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their respective Commitments, as adjusted pursuant to such assignment.

(f) Dissemination of Information . The Company authorizes each Bank to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a “ Transferee ”) and any prospective Transferee any and all information in such Bank’s possession concerning the creditworthiness of the Company and its Subsidiaries; provided that each Transferee and prospective Transferee agrees to be bound by Section 10.09 of this Agreement.

(g) Tax Treatment . If any interest in any Loan Document is transferred to any Transferee which is organized under the laws of any jurisdiction other than the United States or any State thereof, the transferor Bank shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 3.06(g) .

10.09 Confidentiality . Each Bank agrees to take and to cause its Affiliates to take normal and reasonable precautions and exercise due care to maintain the confidentiality of all information identified as “confidential” or “secret” by the Company and provided to it by the Company or any Subsidiary, or by the Administrative Agent on the Company’s or such Subsidiary’s behalf, under this Agreement or any other Loan Document, and neither it nor any of its Affiliates shall use any such information other than in connection with or in enforcement of this Agreement and the other Loan Documents or in connection with other business now or hereafter existing or contemplated with the Company or any Subsidiary; except to the extent such information (i) was or becomes generally available to the public other than as a result of disclosure by the Bank, or (ii) was or becomes available on a non-confidential basis from a source other than the Company, provided that such source is not bound by a confidentiality agreement with the Company known to the Bank; provided that any Bank may disclose such information (A) at the request or pursuant to any requirement of any Governmental Authority to which the Bank is subject or in connection with an examination of such Bank by any such authority; (B) pursuant to subpoena or other court process; (C) when required to do so in accordance with the provisions of any applicable Requirement of Law; (D) to the extent reasonably required in connection with any litigation or proceeding to which the Administrative Agent, any Bank or their respective Affiliates may be party; (E) to the extent reasonably required

709152408 03173762

Notwithstanding anything herein to the contrary, the Administrative Agent, each Issuer and each Bank may disclose to any Person, without limitation of any kind, the U.S. tax treatment and tax structure of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to the Administrative Agent, any Issuer or any Bank relating to such U.S. tax treatment and tax structure.

10.10 Set-off; Ratable Payments . In addition to, and without limitation of, any rights of the Banks under applicable law, if any Event of Default occurs and is continuing, any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other Indebtedness at any time held or owing by any Bank or any Affiliate of any Bank to or for the credit or account of the Company may be offset and applied toward the payment of the Obligations owing to such Bank, whether or not the Obligations, or any part hereof, shall then be due; provided that in the event that any Defaulting Bank shall exercise any such right of setoff, (x) all amounts so set off shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 2.18 and, pending such payment, shall be segregated by such Defaulting Bank from its other funds and deemed held in trust for the benefit of the Administrative Agent, the Issuers, and the Banks, and (y) the Defaulting Bank shall provide promptly to the Administrative Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Bank as to which it exercised such right of setoff. If any Bank, whether by setoff or otherwise, has payment made to it upon its Loans or its participations in Letters of Credit (other than payments received pursuant to Section 3.01 , 3.02 , 3.05 or 3.06 and payments made to any Issuer in respect of Reimbursement Obligations so long as the Banks have not funded their participations therein) in a greater proportion than that received by any other Bank, such Bank agrees, promptly upon demand, to purchase a portion of the Outstanding Credit Exposures held by the other Banks so that after such purchase each Bank will hold its Pro Rata Share of the Aggregate Outstanding Credit Exposure. If any Bank, whether in connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Bank agrees, promptly upon demand, to take such action necessary such that all Banks share in the benefits of such collateral ratably in accordance with their respective Pro Rata Shares. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

709152408 03173762

If there are insufficient funds in such deposit accounts to cover the amount of the fee or other cost or expense then due, such debits will be reversed (in whole or in part, in the Administrative Agent’s and/or U.S. Bank’s sole discretion) and such amount not debited shall be deemed to be unpaid. No such debit under this Section shall be deemed a set-off.

10.12 Notification of Addresses, Lending Installations, Etc . Each Bank shall promptly notify the Administrative Agent in writing of any changes in the address to which notices to the Bank should be directed, of addresses of any Lending Installation, of payment instructions in respect of all payments to be made to it hereunder and of such other administrative information as the Administrative Agent shall reasonably request.
