NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The accompanying unaudited consolidated financial statements and notes should be read in conjunction with our 2005 Form 10-K. In our opinion, all adjustments necessary for a fair statement of the results for the interim periods have been made. The results of operations for an interim period are not necessarily indicative of the results to be expected for the full year. NOTE 1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES Certain reclassifications have been made to prior years' amounts to conform to current year classifications. We revised our Consolidated Statement of Cash Flows for the quarter ended June 30, 2005, to reconcile Net Income to Cash from Operating Activities. Previously, we reconciled Income from Continuing Operations to Cash from Operating Activities. In addition, we have reclassified certain amounts in our balance sheet, statement of income, statement of cash flows and segment information to reflect discontinued operations treatment for our telecommunications business, which we sold in December 2005. These reclassifications had no effect on previously reported consolidated net income, shareholders' equity, comprehensive income or cash flows. INVENTORIES. Inventories are stated at the lower of cost or market. Cost is determined by the average cost method. JUNE 30, DECEMBER 31, INVENTORIES 2006 2005 - -------------------------------------------------------------------------------- MILLIONS Fuel $20.0 $11.0 Materials and Supplies 22.1 22.1 - -------------------------------------------------------------------------------- Total Inventories $42.1 $33.1 - -------------------------------------------------------------------------------- STOCK-BASED COMPENSATION EXPENSE. Effective January 1, 2006, we adopted the fair value recognition provisions of SFAS 123R, "Share-Based Payment," using the modified prospective transition method. Under this method, we recognize compensation expense for all share-based payments granted after January 1, 2006, and those granted prior to but not yet vested as of January 1, 2006. Under the fair value recognition provisions of SFAS 123R, we recognize stock-based compensation net of an estimated forfeiture rate and only recognize compensation expense for those shares expected to vest over the required service period of the award. Prior to our adoption of SFAS 123R, we accounted for share-based payments under Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" and related interpretations. STOCK INCENTIVE PLAN. Under our Executive Long-Term Incentive Compensation Plan, share-based awards may be issued to employees via a broad range of methods, including non-qualified and incentive stock options, performance shares, performance units, restricted stock, stock appreciation rights and other awards. There are 3.2 million shares of common stock reserved for issuance under the plan, with 1.6 million of these shares available for issuance as of June 30, 2006. We currently have the following types of share-based awards outstanding: NON-QUALIFIED STOCK OPTIONS. The options allow for the purchase of shares of common stock at a price equal to the common stock's market value at the date of grant. Options become exercisable beginning one year after the grant date, with one-third vesting each year over three years. Options may be exercised up to ten years following the date of grant. In the case of qualified retirement, death or disability, options vest immediately and the period over which the options can be exercised is shortened. Employees have up to three months to exercise vested options upon voluntary termination or involuntary termination without cause. All options are cancelled upon termination for cause. All options vest immediately upon a change of control, as defined in the award agreement. We determine the fair value of options using the Black-Scholes option pricing model. The estimated fair value of options, including the effect of estimated forfeitures, is recognized as expense on the straight-line basis over the options' vesting periods. 7 ALLETE Second Quarter 2006 Form 10-Q

NOTE 1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) The following assumptions were used in determining the fair value of stock options granted during the first six months of 2006, under the Black-Scholes option-pricing model: 2006 - -------------------------------------------------------------------------------- Risk-Free Interest Rate 4.5% Expected Life 5 Years Expected Volatility 20% Dividend Growth Rate 5% - -------------------------------------------------------------------------------- The risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the grant date. Expected volatility is based on the historic volatility of our stock and the stock of our peer group companies. We utilize historical option exercise and employee termination data to estimate the option life. Dividend growth rate is based upon historic growth rates in our dividends and the dividends of our peer group companies. PERFORMANCE SHARES. Under these awards, the number of shares earned is contingent upon attaining specific performance targets over a three-year performance period. In the case of qualified retirement, death or disability during a performance period, a pro-rata portion of the award will be earned at the conclusion of the performance period based on the performance goals achieved. In the case of termination of employment for any reason other than qualified retirement, death or disability, no award will be earned. If there is a change in control, a pro-rata portion of the award will be paid based on the greater of actual performance up to the date of the change in control or target performance. The fair value of these awards is equal to the grant date fair value which is estimated based upon the assumed share-based payment three years from the date of grant. Compensation cost is recognized over the three-year performance period based on our estimate of the number of shares which will be earned by the award recipients. EMPLOYEE STOCK PURCHASE PLAN (ESPP). Under our ESPP, eligible employees may purchase ALLETE common stock at a 5 percent discount from the market price. Because the discount is not greater than 5 percent, we are not required by SFAS 123R to apply fair value accounting to these awards. RETIREMENT SAVINGS AND STOCK OWNERSHIP PLAN (RSOP). Shares held in our RSOP are excluded from SFAS 123R and are accounted for in accordance with the American Institute of Certified Public Accountants' Statement of Position No. 93-6, "Employers' Accounting for Employee Stock Ownership Plans." The following share-based compensation expense amounts were recognized in our consolidated statement of income for the periods presented since our adoption of FAS 123R. QUARTER ENDED SIX MONTHS ENDED JUNE 30, JUNE 30, SHARE-BASED COMPENSATION EXPENSE 2006 2006 - -------------------------------------------------------------------------------- MILLIONS Stock Options $0.2 $0.4 Performance Shares 0.3 0.5 - -------------------------------------------------------------------------------- Total Share-Based Compensation Expense $0.5 $0.9 - -------------------------------------------------------------------------------- Income Tax Benefit $0.2 $0.4 - -------------------------------------------------------------------------------- There were no significant capitalized stock-based compensation costs at June 30, 2006. As of June 30, 2006, the total compensation cost for nonvested awards not yet recognized in our statements of income was $2.2 million. This amount is expected to be recognized over a weighted-average period of 1.3 years. ALLETE Second Quarter 2006 Form 10-Q 8

FSP INTERPRETATION NO. 46(R)-6. In April 2006, the FASB issued Staff Position Interpretation No. 46(R)-6, "Determining the Variability to Be Considered in Applying FASB Interpretation No. 46(R)," which addresses how an enterprise should determine the variability to be considered in applying FASB Interpretation No. 46, "Consolidation of Variable Interest Entities." The variability that is considered in applying Interpretation No. 46(R) affects the determination of: (a) whether the entity is a variable interest entity (VIE); (b) which interests are variable interests in the entity; and (c) which party, if any, is the primary beneficiary of the VIE. This FSP provides a guide for the qualitative analysis of the design of the entity and clarifying guidance to assist in determining the variability to consider in applying Interpretation No. 46(R), determining which interests are variable interests, and ultimately determining which variable interest holder, if any, is the primary beneficiary. FSP Interpretation No. 46(R)-6 is applied prospectively to all entities with which the Company first becomes involved and to all entities previously required to be analyzed under Interpretation No. 46(R) when a reconsideration event has occurred, effective as of the first day of the first reporting period after June 15, 2006. We do not expect this FSP to have a material impact on existing contracts. We will evaluate the impact of this new guidance on any new contracts or any changes to existing contracts executed after the effective date to determine applicability of this FSP. INTERPRETATION NO. 48. In June 2006, the FASB issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement No. 109." Interpretation No. 48 clarifies the accounting for uncertain tax positions in accordance with SFAS 109, "Accounting for Income Taxes." The Company will be required to recognize in its financial statements the largest tax benefit of a tax position that is "more-likely-than-not" to be sustained on audit based solely on the technical merits of the position as of the reporting date. The term "more-likely-than-not" means a likelihood of more than 50 percent. Interpretation No. 48 also provides guidance on new disclosure requirements, reporting and accrual of interest and penalties, accounting in interim periods and transition. Interpretation No. 48 is effective as of the beginning of the first fiscal year after December 15, 2006, which will be as of January 1, 2007, for calendar-year companies. Only tax positions that meet the "more-likely-than-not" threshold at that date may be recognized. The cumulative effect of initially applying Interpretation No. 48 will be recognized as a change in accounting principle as of the end of the period in which Interpretation No. 48 is adopted. The Company has begun an evaluation of the impact of applying this interpretation as of January 1, 2007, which will be the effective date of the interpretation for the Company. We do not expect Interpretation No. 48 to have a material impact on our financial position, results of operation or cash flows. ALLETE Second Quarter 2006 Form 10-Q 10

NOTE 2. BUSINESS SEGMENTS Financial results by segment for the periods presented were impacted by the integration of our Taconite Harbor facility into the Regulated Utility segment effective January 1, 2006. The redirection of Taconite Harbor from our Nonregulated Energy Operations segment to our Regulated Utility segment was in accordance with the Company's Resource Plan, as approved by the MPUC. Under the terms of our Resource Plan, we have operated the Taconite Harbor facility as a rate-based asset within the Minnesota retail jurisdiction effective January 1, 2006.

NOTE 3. INVESTMENTS SHORT-TERM INVESTMENTS. At June 30, 2006 and December 31, 2005, we held $120.4 million and $116.9 million, respectively, of short-term investments, consisting of auction rate bonds and variable rate demand notes classified as available-for-sale securities. Our investments in these securities are recorded at fair market value which equates to cost because the variable interest rates for these securities typically reset every 7 to 35 days. Despite the long-term nature of their stated contractual maturities, we have the ability to quickly liquidate these securities. As a result, we had no cumulative gross unrealized holding gains (losses) or gross realized gains (losses) from our short-term investments. All income generated from these short-term investments was recorded as interest income. LONG-TERM INVESTMENTS. At June 30, 2006, Investments included the real estate assets of ALLETE Properties, our investment in ATC, debt and equity securities consisting primarily of securities held to fund employee benefits, and our emerging technology investments.

NOTE 4. SHORT-TERM AND LONG-TERM DEBT In January 2006, we renewed, increased and extended a committed, syndicated, unsecured revolving credit facility (Line) with LaSalle Bank National Association, as Agent, for $150 million ($100 million at December 31, 2005). The Line matures on January 11, 2011, and requires an annual commitment fee of 0.125%. At our request and subject to certain conditions, the Line may be increased to $200 million and extended for two additional 12-month periods. The Line may be used for general corporate purposes, working capital and to provide liquidity in support of our commercial paper program. We may prepay amounts outstanding under the Line in whole or in part at our discretion without premium or penalty. Additionally, we may irrevocably terminate or reduce the size of the Line prior to maturity without premium or penalty. No funds were drawn under this Line at June 30, 2006. In March 2006, we issued $50 million in principal amount of First Mortgage Bonds, 5.69% Series due March 1, 2036. Proceeds were used to redeem $50 million in principal amount of First Mortgage Bonds, 7% Series due March 1, 2008. 13 ALLETE Second Quarter 2006 Form 10-Q

NOTE 4. SHORT-TERM AND LONG-TERM DEBT (CONTINUED) On July 5, 2006, the Collier County Industrial Development Authority issued $27.8 million of Industrial Development Variable Rate Demand Refunding Revenue Bonds Series 2006 due 2025 (Refunding Bonds) on behalf of ALLETE. Proceeds from the Refunding Bonds and internally generated funds will be used to redeem $29.1 million of outstanding Collier County Industrial Development Refunding Revenue Bonds 6.5% Series 1996 due 2025 which were called on July 5, 2006, for redemption on August 9, 2006. As a result of an early redemption premium, we will recognize a $0.6 million charge to other expense in the third quarter of 2006. NOTE 5. COMMON STOCK SHAREHOLDER RIGHTS PLAN. In 1996, we adopted a rights plan that provides for a dividend distribution of one preferred share purchase right (Right) to be attached to each share of common stock. In July 2006, we amended the rights plan to extend the expiration of the Rights to July 11, 2009. The amendment also provides that the Company may not consolidate, merge, or sell a majority of its assets or earning power if doing so would be counter to the intended benefits of the Rights or would result in the distribution of Rights to the shareholders of the other parties to the transaction. Finally, the amendment provides for the creation of a committee of independent directors to annually review the terms and conditions of the amended rights plan (Rights Plan), as well as to consider whether termination or modification of the Rights Plan would be in the best interests of the shareholders and to make a recommendation based on such review to the Board of Directors. The Rights, which are currently not exercisable or transferable apart from our common stock, entitle the holder to purchase one-and-a-half one-hundredths (three two-hundredths) of a share of ALLETE's Junior Serial Preferred Stock A, without par value. The purchase price, as defined in the Rights Plan, remains at $90. These Rights would become exercisable if a person or group acquires beneficial ownership of 15 percent or more of our common stock or announces a tender offer which would increase the person's or group's beneficial ownership interest to 15 percent or more of our common stock, subject to certain exceptions. If the 15 percent threshold is met, each Right entitles the holder (other than the acquiring person or group) to receive, upon payment of the purchase price, the number of shares of common stock (or, in certain circumstances, cash, property or other securities of ours) having a market value equal to twice the exercise price of the Right. If we are acquired in a merger or business combination, or 50 percent or more of our assets or earning power are sold, each exercisable Right entitles the holder to receive, upon payment of the purchase price, the number of shares of common stock of the acquiring or surviving company having a value equal to twice the exercise price of the Right. Certain stock acquisitions will also trigger a provision permitting the Board of Directors to exchange each Right for one share of our common stock. The Rights are nonvoting and may be redeemed by us at a price of $0.005 per Right at any time they are not exercisable. One million shares of Junior Serial Preferred Stock A have been authorized and are reserved for issuance under the Rights Plan. NOTE 6. KENDALL COUNTY CHARGE On April 1, 2005, Rainy River Energy, a wholly-owned subsidiary of ALLETE, completed the assignment of its power purchase agreement with LSP-Kendall Energy, LLC, the owner of an energy generation facility located in Kendall County, Illinois, to Constellation Energy Commodities. Rainy River Energy paid Constellation Energy Commodities $73 million in cash to assume the power purchase agreement that remains in effect through mid-September 2017. The payment resulted in a charge to our operating income in the second quarter of 2005. The tax benefits of the payment will be realized through a capital loss carryback for federal income tax purposes and have been recorded as current deferred income tax assets. The tax benefits are expected to be realized in 2006. In addition, consent, advisory and closing costs of $4.9 million were incurred to complete the transaction. As a result of this transaction, ALLETE incurred a charge to operating expenses totaling $77.9 million ($50.4 million after tax, or $1.84 per diluted share) in the second quarter of 2005.

(See Note 6.) For the six months ended June 30, 2006, the effective rate for income taxes was 37.3 percent (32.5 percent benefit for the six months ended June 30, 2005). The increase in the effective rate over last year was primarily due to the emerging technology impairment and the Kendall County capital loss recorded in April 2005. The current benefit for these items was limited to the federal benefit as the state net capital loss carryforwards from 2005 are entirely reserved. The effective rate of 37.3 percent for the six months ended June 30, 2006, was less than the statutory rate primarily because of investment tax credits, and deductions for Medicare health subsidies and depletion. 15 ALLETE Second Quarter 2006 Form 10-Q

NOTE 9. DISCONTINUED OPERATIONS ENVENTIS TELECOM. On December 30, 2005, we sold all the stock of our telecommunications subsidiary, Enventis Telecom, to Hickory Tech Corporation of Mankato, Minnesota. In accordance with SFAS 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," we reported our telecommunications business in discontinued operations for the quarter and six months ended June 30, 2005. WATER SERVICES. In early 2005, we completed the exit from our Water Services businesses with the sale of our wastewater assets in Georgia, which resulted in an immaterial gain. In 2005, the Florida Public Service Commission approved the transfer of 63 water and wastewater systems from Florida Water to Aqua Utilities Florida, Inc. (Aqua Utilities) and ordered a $1.7 million reduction to plant investment. The Company reserved for the reduction in 2005. On March 15, 2006, the Company paid Aqua Utilities the adjustment refund amount of $1.7 million. For the quarter and six months ended June 30, 2006, financial results reflected additional legal and administrative expenses to exit the Water Services businesses.

NOTE 13. COMMITMENTS, GUARANTEES AND CONTINGENCIES OFF-BALANCE SHEET ARRANGEMENTS. SQUARE BUTTE POWER PURCHASE AGREEMENT. Minnesota Power has a power purchase agreement with Square Butte that extends through 2026 (Agreement). It provides a long-term supply of low-cost energy to customers in our electric service territory and enables Minnesota Power to meet power pool reserve requirements. Square Butte, a North Dakota cooperative corporation, owns a 455-MW coal-fired generating unit (Unit) near Center, North Dakota. The Unit is adjacent to a generating unit owned by Minnkota Power, a North Dakota cooperative corporation whose Class A members are also members of Square Butte. Minnkota Power serves as the operator of the Unit and also purchases power from Square Butte. Minnesota Power was entitled to approximately 71 percent of the Unit's output under the Agreement. Beginning in 2006, Minnkota Power exercised its option to reduce Minnesota Power's entitlement by approximately 5 percent annually, to 66 percent. We received notices from Minnkota Power that they will further reduce our output entitlement by approximately 5 percent on January 1, 2007 and 2008, to 60 percent and 55 percent, respectively. Minnkota Power has the option to reduce Minnesota Power's entitlement to 50 percent. Minnesota Power is obligated to pay its pro rata share of Square Butte's costs based on Minnesota Power's entitlement to Unit output. Minnesota Power's payment obligation will be suspended if Square Butte fails to deliver any power, whether produced or purchased, for a period of one year. Square Butte's fixed costs consist primarily of debt service. At June 30, 2006, Square Butte had total debt outstanding of $304.6 million. Total annual debt service for Square Butte is expected to be approximately $26 million in each of the years 2006 through 2010. Variable operating costs include the price of coal purchased from BNI Coal, our subsidiary, under a long-term contract. Minnesota Power's payments to Square Butte are approved as a purchased power expense for ratemaking purposes by both the MPUC and the FERC. LEASING AGREEMENTS. BNI Coal is obligated to make lease payments for a dragline totaling $2.8 million annually for the lease term which expires in 2027. BNI Coal has the option at the end of the lease term to renew the lease at a fair market rental, to purchase the dragline at fair market value, or to surrender the dragline and pay a $3.0 million termination fee. We lease other properties and equipment under operating lease agreements with terms expiring through 2013. The aggregate amount of minimum lease payments for all operating leases is $6.4 million in 2006, $5.9 million in 2007, $5.2 million in 2008, $4.7 million in 2009, $4.2 million in 2010 and $46.9 million thereafter. COAL, RAIL AND SHIPPING CONTRACTS. We have three coal supply agreements with various expiration dates ranging from December 2006 to December 2009. We also have rail and shipping agreements for transportation of all of our coal, with various expiration dates ranging from December 2006 to December 2011. Our minimum annual payment obligations under these coal, rail and shipping agreements are currently $45.2 million in 2006, $9.5 million in 2007, $9.7 million in 2008, $5.8 million in 2009 and no specific commitments beyond 2009. Our minimum annual payment obligations will increase when annual nominations are made for coal deliveries in future years. FUEL CLAUSE RECOVERY OF MISO DAY 2 COSTS. Minnesota Power filed a petition with the MPUC in February 2005 to amend its fuel clause to accommodate costs and revenue related to the MISO Day 2 energy market, the market through which Minnesota Power engages in wholesale energy transactions in MISO's day-ahead and real-time markets (MISO Day 2). On April 7, 2005, the MPUC approved interim accounting treatment of MISO Day 2 costs to be accounted for on a net basis and recovered through the fuel clause, subject to refund with interest. This interim treatment has continued while the MPUC has addressed the cost recovery petitions from Xcel Energy Inc., Otter Tail Power Company, Alliant Energy Corporation and Minnesota Power. On December 21, 2005, the MPUC issued an order which denied recovery through the fuel clause of uplift charges, congestion revenue and expenses, and administrative costs related to Minnesota Power's MISO Day 2 market activities. Minnesota Power requested rehearing of the order in a filing made with the MPUC on January 10, 2006. The other three utilities affected by the order also filed for rehearing, as did the DOC and MISO. In a hearing on February 9, 2006, the MPUC granted rehearing of the MISO Day 2 docket and suspended the refund obligation for charges recovered through the fuel clause denied in the December 21, 2005 order. The MPUC requested that the affected utilities and interested parties provide a joint recommendation regarding the MISO Day 2 costs to determine which costs should be recovered on a current basis through the fuel clause and which costs are more appropriately deferred for 19 ALLETE Second Quarter 2006 Form 10-Q

The Company is unable to predict the outcome of this matter. EMERGING TECHNOLOGY PORTFOLIO. We have investments in emerging technologies through minority investments in venture capital funds structured as limited liability companies, and direct investments in privately-held, start-up companies. The carrying value of our direct investments in privately-held, start-up companies was zero at June 30, 2006, and December 31, 2005. We have committed to make additional investments in certain emerging technology venture capital funds. The total future commitment was $2.5 million at June 30, 2006 ($3.1 million at December 31, 2005), and may be invested at various times through 2007. We do not have plans to make any additional investments beyond this commitment. INVESTMENT IN ATC. In December 2005, we entered into an agreement with Wisconsin Public Service Corporation and WPS Investments, LLC that provides for our Wisconsin subsidiary, Rainy River Energy Corporation - Wisconsin, to invest $60 million in ATC. Our investment is expected to represent an estimated 9 percent ownership interest in ATC. On May 4, 2006, the PSCW reviewed and approved the request that allows us to invest in ATC. As of June 30, 2006, we had invested $11.5 million in ATC and anticipate investing an additional $48.5 million by the end of 2006. ENVIRONMENTAL MATTERS. Our businesses are subject to regulation of environmental matters by various federal, state and local authorities. Due to future stricter environmental requirements through legislation and/or rulemaking, we anticipate that potential expenditures for environmental matters will be material and will require significant capital investments. We review environmental matters on a quarterly basis. Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. These accruals are adjusted periodically as assessment and remediation efforts progress or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the balance sheet at undiscounted amounts and exclude claims for recoveries from insurance or other third parties. Costs related to environmental contamination treatment and cleanup are charged to expense unless recoverable in rates from customers. SWL&P MANUFACTURED GAS PLANT. In May 2001, SWL&P received notice from the WDNR that the City of Superior had found soil contamination on property adjoining a former Manufactured Gas Plant (MGP) site owned and operated by SWL&P from 1889 to 1904. The WDNR requested SWL&P to initiate an environmental investigation. The WDNR also issued SWL&P a Responsible Party letter in February 2002. In February 2003, SWL&P submitted a Phase II environmental site investigation report to the WDNR. This report identified some MGP-like chemicals that were found in the soil near the former plant site. During March and April 2003, sediment samples were taken from nearby Superior Bay. The report on the results of this sampling was completed and sent to the WDNR during the first quarter of 2004. The next phase of the investigation was to determine any impact to soil or ground water between the former MGP site and Superior Bay. Site work for this phase of the investigation was performed during October 2004, and a report was sent to the WDNR in March 2005. Additional site investigation was performed during September and October 2005. The investigation will continue through the summer of 2006. It is anticipated that the final report for this portion of the investigation will be completed by the end of 2006. Although it is not possible to quantify the potential clean-up cost until the investigation is completed, a $0.5 million liability was recorded in December 2003 to address the known areas of contamination. The Company has recorded a corresponding dollar amount as a regulatory asset to offset this liability. The PSCW has approved SWL&P's deferral of these MGP environmental investigation and potential clean-up costs for future recovery in rates, subject to a regulatory prudency review. In May 2005, the PSCW approved the collection through rates of $150,000 of site investigation costs that had been incurred at the time SWL&P filed their 2005 rate request. In May 2006, SWL&P filed an application with the PSCW for authority to increase retail utility rates by an average of 5.2 percent. This filing includes a request to recover an additional $186,000 of site investigation costs that had been incurred through 2005. ALLETE maintains pollution liability insurance coverage that includes coverage for SWL&P. A claim has been filed with respect to this matter. The insurance carrier has issued a reservation of rights letter and the Company continues to work with the insurer to determine the availability of insurance coverage.

NOTE 13. COMMITMENTS, GUARANTEES AND CONTINGENCIES (CONTINUED) SQUARE BUTTE GENERATING FACILITY. On April 24, 2006, Minnkota Power announced a settlement agreement with the EPA and the State of North Dakota regarding emissions at the M.R. Young Station, which includes the Square Butte generating unit. In June 2002, Minnkota Power, the operator of Square Butte, received a Notice of Violation from the EPA regarding alleged New Source Review violations at the M.R. Young Station. The EPA claimed certain capital projects completed by Minnkota Power should have been reviewed pursuant to the New Source Review regulations, potentially resulting in new air permit operating conditions and possible significant capital expenditures to comply. As a result of the settlement agreement, the current Square Butte flue gas desulfurization system (FGD) will be upgraded in 2010 to increase its removal efficiency from 70 percent to 90 percent, and an over-fire air system will also be installed in 2007 to reduce NOx emissions. Capital expenditures for the emission control additions and modifications on Square Butte are estimated at $35 million. These estimated capital expenditures may be significantly offset by the sale of surplus SO2 allowance credits created by the early upgrade of the FGD system, which is being upgraded two years earlier than required by Federal rules. We expect Square Butte will utilize debt to finance such capital expenditures. Our future cost of purchased power from the Square Butte generating unit would include our pro rata share of this additional debt service. On April 24, 2006, a Complaint and a Consent Decree with respect to this settlement agreement were filed in U.S. District Court for the District of North Dakota (Court). The Consent Decree was open to public comment during which time one comment letter was received from the Dakota Resource Council. We believe the items raised in the letter will not compromise the agreement and Minnkota Power expects the final order will be issued by the Court constituting a final settlement of this issue. On July 25, 2006, the EPA filed a motion with the Court to approve the Consent Decree. When finalized, the Consent Decree settlement would also require Square Butte to pay approximately $0.6 million in administrative costs and penalties in 2006, and $3.3 million toward additional environmental projects including wind power installations or power purchase agreements. Minnesota Power is obligated to pay its pro rata share of Square Butte's costs based on Minnesota Power's entitlement to the output from the Square Butte generating unit. EPA CLEAN AIR INTERSTATE RULE AND CLEAN AIR MERCURY RULE. In March 2005, the EPA announced the final Clean Air Interstate Rule (CAIR) that reduces and permanently caps emissions of SO2 and NOx in many states in the eastern United States. The CAIR includes Minnesota as one of the 28 states it considers an "eastern" state. The EPA also announced the final Clean Air Mercury Rule (CAMR) that reduces and permanently caps electric utility mercury emissions in the continental United States. The CAIR and the CAMR regulations have been challenged in the federal court system, which may delay implementation or modify provisions. Minnesota Power is participating in a legal challenge to the CAIR, but is not participating in the challenge of the CAMR. However, if the CAMR and the CAIR do go into effect, Minnesota Power expects to be required to: (1) make emissions reductions; (2) purchase mercury; SO2 and NOx allowances through the EPA's cap-and-trade system; or (3) use a combination of both. We believe that the CAIR contains flaws in its methodology and application, which will cause Minnesota Power to incur higher compliance costs. Consequently, on July 11, 2005, Minnesota Power filed a Petition for Review with the U.S. Court of Appeals for the District of Columbia Circuit (Court of Appeals). On November 22, 2005, the EPA agreed to reconsider certain aspects of the CAIR, including the Minnesota Power petition addressing modeling used to determine Minnesota's inclusion in the CAIR region and our claims about inequities in the SO2 allowance methodology. On March 15, 2006, the EPA announced that it would not make any changes to the CAIR as a result of the petitions for reconsideration. Petitions for Review (including Minnesota Power's) remain pending at the Court of Appeals. If the Petitions for Review filed with the Court of Appeals are successful, we expect to incur lower compliance costs, consistent with the rules applicable to those states considered as "western" states under the CAIR. Resolution of the CAIR Petition for Review with the Court of Appeals is anticipated by mid-2007. 21 ALLETE Second Quarter 2006 Form 10-Q

NOTE 13. COMMITMENTS, GUARANTEES AND CONTINGENCIES (CONTINUED) COMMUNITY DEVELOPMENT DISTRICT OBLIGATIONS. TOWN CENTER. In March 2005, the Town Center District issued $26.4 million of tax-exempt, 6% Capital Improvement Revenue Bonds, Series 2005, due May 1, 2036. The bonds were issued to fund a portion of the Town Center development project. Approximately $21 million of the bond proceeds will be used for construction of infrastructure improvements at Town Center, with the remaining funds to be used for capitalized interest, a debt service reserve fund and costs of issuance. The bonds are payable from and secured by the revenue derived from assessments imposed, levied and collected by the Town Center District. The assessments represent an allocation of the costs of the improvements, including bond financing costs, to the lands within the Town Center District benefiting from the improvements. The assessments will be included in the annual property tax bills of landowners beginning in November 2006. To the extent that we still own land at the time of the assessment, in accordance with EITF 91-10, we will recognize an expense for our pro rata portion of assessments, based upon our ownership of benefited property. At June 30, 2006, we owned approximately 85 percent of the assessable land in the Town Center District. PALM COAST PARK. In May 2006, the Palm Coast District issued $31.8 million of tax-exempt, 5.7% Special Assessment Bonds, Series 2006, due May 1, 2037. The bonds were issued to fund a portion of the Palm Coast Park development project. Bond proceeds of $26.3 million will be used for the construction of environmental, traffic mitigation and infrastructure improvements, including utility extensions, roadways, parks, drainage, recreational facilities, landscaping and a multi-purpose trail system. The remaining funds will be used for capitalized interest, a debt service reserve fund and the costs of issuance. The bonds are payable from and secured by the revenue derived from assessments imposed, levied and collected by the Palm Coast District. The assessments represent an allocation of the costs of the improvements, including bond financing costs, to the lands within the Palm Coast District benefiting from the improvements. The assessments will be included in the annual property tax bills of landowners beginning in 2007. To the extent that we still own land at the time of the assessment, in accordance with EITF 91-10, we will recognize an expense for our pro rata portion of assessments, based upon our ownership of benefited property. At June 30, 2006, we owned all assessable land in the Palm Coast District. OTHER. We are involved in litigation arising in the normal course of business. Also in the normal course of business, we are involved in tax, regulatory and other governmental audits, inspections, investigations and other proceedings that involve state and federal taxes, safety, compliance with regulations, rate base and cost of service issues, among other things. While the resolution of such matters could have a material effect on earnings and cash flows in the year of resolution, none of these matters are expected to materially change our present liquidity position, nor have a material adverse effect on our financial condition.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion should be read in conjunction with our consolidated financial statements and notes to those statements and the other financial information appearing elsewhere in this report. In addition to historical information, the following discussion and other parts of this report contain forward-looking information that involves risks and uncertainties. Readers are cautioned that forward-looking statements should be read in conjunction with our disclosures in this Form 10-Q under the headings: "Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995" located on page 3 and "Risk Factors" located in Part I, Item 1A of our 2005 Form 10-K and Part II, Item 1A of our Quarterly Reports on Form 10-Q for 2006. The risks and uncertainties described in this Form 10-Q and our 2005 Form 10-K are not the only risks facing our Company. Additional risks and uncertainties that we are not presently aware of, or that we currently consider immaterial, may also affect our business operations. Our business, financial condition or results of operations could suffer if the concerns set forth are realized. EXECUTIVE SUMMARY ALLETE's operations focus on two core businesses - ENERGY and REAL ESTATE. In addition, we have other operations that provide earnings to the Company. ENERGY is comprised of Regulated Utility, Nonregulated Energy Operations and will include Investment in ATC. - REGULATED UTILITY includes retail and wholesale rate regulated electric, water and gas services in northeastern Minnesota and northwestern Wisconsin under the jurisdiction of state and federal regulatory authorities. - NONREGULATED ENERGY OPERATIONS includes our coal mining activities in North Dakota, approximately 50 MW of nonregulated generation and Minnesota land sales. In 2005, Nonregulated Energy Operations also included nonregulated generation (non-rate base generation sold at market-based rates primarily to the wholesale market) from our Taconite Harbor facility in northern Minnesota, and generation secured through the Kendall County power purchase agreement. Effective January 1, 2006, Taconite Harbor was integrated into our Regulated Utility business to help meet forecasted base load energy requirements. In April 2005, the Kendall County power purchase agreement was assigned to Constellation Energy Commodities. - INVESTMENT IN ATC includes our ownership interest in ATC. In December 2005, we entered into an agreement that provides for us to invest $60 million in ATC. As of June 30, 2006, we had invested $11.5 million in ATC and anticipate investing an additional $48.5 million by the end of 2006. REAL ESTATE includes our Florida real estate operations. OTHER includes our investments in emerging technologies, and earnings on cash, cash equivalents and short-term investments. Financial results by segment for the periods presented and discussed in this Form 10-Q were impacted by the integration of our Taconite Harbor facility into the Regulated Utility segment effective January 1, 2006. The redirection of Taconite Harbor from our Nonregulated Energy Operations segment to our Regulated Utility segment was in accordance with the Company's Resource Plan, as approved by the MPUC. Under the terms of our Resource Plan, we have operated the Taconite Harbor facility as a rate-based asset within the Minnesota retail jurisdiction effective January 1, 2006. Prior to January 1, 2006, we operated our Taconite Harbor facility as nonregulated generation. Historical financial results of Taconite Harbor for periods prior to the redirection are included in our Nonregulated Energy Operations segment. Financial results for the periods presented and discussed in this Form 10-Q were also impacted by the assignment of our Kendall County power purchase agreement to Constellation Energy Commodities, which was a key strategic accomplishment for the Company. As a result of this assignment, we incurred a charge to our operating expenses totaling $77.9 million ($50.4 million after tax, or $1.84 per diluted share) in the second quarter of 2005 (Kendall County Charge). 23 ALLETE Second Quarter 2006 Form 10-Q

EXECUTIVE SUMMARY (CONTINUED) Net income for the quarter ended June 30, 2006, was $13.2 million, or $0.47 per diluted share (a $40.3 million, or $1.48 per diluted share, net loss for the quarter ended June 30, 2005). Net income was higher in 2006 due to the absence of the $50.4 million, or $1.84 per share, Kendall County Charge incurred in the second quarter of 2005, a $2.8 million increase in income from Real Estate and a $0.8 million increase in earnings on our excess cash. Net income for the six months ended June 30, 2006, was $32.0 million, or $1.15 per diluted share (a $22.9 million, or $0.84 per diluted share, net loss for the six months ended June 30, 2005). Net income was higher in 2006 due to the absence of: (1) the $50.4 million, or $1.84 per share, Kendall County Charge incurred in the second quarter of 2005; (2) Kendall County operating losses ($1.9 million in 2005); and (3) emerging technology impairments ($3.3 million in 2005).

NET INCOME The following income discussion summarizes a comparison of the six months ended June 30, 2006, to the six months ended June 30, 2005, by segment. REGULATED UTILITY contributed income of $19.8 million in 2006 ($20.7 million in 2005). Lower earnings in 2006 reflected higher operating expenses partially offset by an 8 percent increase in kilowatthour sales. Operating expenses were higher in 2006 due to the inclusion of Taconite Harbor, effective January 1, 2006, and increased planned maintenance, employee compensation and pension expenses. Electric sales increased 490.7 million kilowatthours, or 8 percent, primarily due to the inclusion of Taconite Harbor and its pre-existing wholesale energy sales obligation. NONREGULATED ENERGY OPERATIONS reported income of $1.8 million in 2006 ($48.9 million loss in 2005). In April 2005, we completed the assignment of our Kendall County power purchase agreement to Constellation Energy Commodities. As a result of this transaction, we incurred a charge to operating expenses totaling $50.4 million after tax in the second quarter of 2005. In 2006, financial results reflected the absence of income from Taconite Harbor ($2.5 million in 2005) which is now reported as part of Regulated Utility and operating losses from Kendall County ($1.9 million in 2005). Net income from our coal operations was up $0.5 million from 2005 primarily due to a 2 percent increase in tons of coal sold. ALLETE Second Quarter 2006 Form 10-Q 26

NET INCOME (CONTINUED) REAL ESTATE contributed income of $10.6 million in 2006 ($9.7 million in 2005). Income was higher in 2006 due to the timing and mix of land sale transaction closings, and increased earnings from prior and current year land sales at our Town Center development project which are accounted for under the percentage-of-completion method. The timing of the closing of real estate sales varies from period to period and impacts comparisons between years. In 2005, we began selling property from our Town Center development project in northeast Florida. Since land is being sold before completion of the project infrastructure, revenue, cost of real estate sold and selling expenses are recorded using the percentage-of-completion method as development obligations are completed. As of June 30, 2006, we had $8.1 million ($11.2 million revenue; $2.7 million cost of real estate sold; $0.4 million selling expense) of deferred profit on sales of real estate, before taxes and minority interest, on our balance sheet. The majority of deferred profit relates to Town Center and we expect most will be reflected in income by the end of 2006. At June 30, 2006, total pending land sales under contract were $128.9 million and are anticipated to close at various times through 2012. Pricing on these contracts range from $20 to $50 per commercial square foot, $8,600 to $40,000 per residential unit and $8,700 to $126,000 per acre for all other properties. The majority of the other properties under contract are zoned commercial or mixed use. Prices per acre are stated on a gross acreage basis and are dependent on the type and location of the properties sold. In addition, certain contracts allow us to receive participation revenue when gross revenue from land sales by our purchaser exceeds contractually defined price levels. Deposits have been made for all pending contracts; however, most pending contracts are subject to due diligence that allows the purchaser to terminate the contract for a period of time. One of the currently pending contracts is subject to an unexpired due diligence period. If a purchaser defaults under a contract, our remedy is limited to forfeiture of the deposit as liquidated and agreed upon damages.

OTHER reflected net income of $0.2 million in 2006 (a $3.9 million loss in 2005). In 2006, a $1.3 million increase in earnings on excess cash offset equity losses related to emerging technology investments ($0.6 million in 2006; $0.2 million in 2005). In 2005, the Company recorded $3.3 million of impairments related to two privately-held emerging technology investments. DISCONTINUED OPERATIONS included our Water Services businesses that we sold over the three-year period from 2003 to 2005, and Enventis Telecom, our telecommunications business that we sold in December 2005. In 2006, discontinued operations reflected a $0.4 million loss for additional legal and administrative expenses related to exiting the Water Services businesses. In 2005, $0.8 million of income from Enventis Telecom was offset by $1.3 million of administrative and other expenses incurred to support Florida Water transfer proceedings.

COMPARISON OF THE QUARTERS ENDED JUNE 30, 2006 AND 2005 REGULATED UTILITY OPERATING REVENUE was up $8.7 million, or 6 percent, from 2005, primarily due to increased kilowatthour sales. Electric sales increased 203.1 million kilowatthours, or 7 percent, due mostly to the addition of Taconite Harbor wholesale power agreements to the Regulated Utility segment effective January 1, 2006. The majority of Taconite Harbor sales are reflected in sales to other power suppliers which were up 148.6 million kilowatthours, or 41 percent, and $6.4 million. Absent the inclusion of pre-existing Taconite Harbor wholesale obligations, sales to other power suppliers were down reflecting less excess energy available for sale due to a planned outage at our Boswell Unit 4 generating facility in 2006. Electric sales to retail and municipal customers increased 54.5 million kilowatthours, or 2 percent, and $0.7 million, due to strong demand from commercial, industrial and municipal customers. Revenue from electric sales to taconite customers accounted for 24 percent of consolidated operating revenue in 2006 (25 percent in 2005). Revenue from electric sales to paper and pulp mills accounted for 9 percent of consolidated operating revenue in both 2006 and 2005. OPERATING EXPENSES were up $10.4 million, or 9 percent, from 2005. FUEL AND PURCHASED POWER EXPENSE. Fuel and purchased power expense was down $0.2 million from 2005 reflecting the inclusion of Taconite Harbor beginning in 2006 ($5.5 million) offset by reduced fuel expense, primarily at our Boswell Unit 4 generating facility due to a planned maintenance outage in 2006. OTHER OPERATING EXPENSES. In total, other operating expenses were up $10.6 million from 2005. In total, plant maintenance expense increased $3.5 million from 2005 reflecting the inclusion of Taconite Harbor maintenance in 2006 ($0.7 million) and increased maintenance expense at other Company generating facilities, primarily due to a planned outage at our Boswell Unit 4 generating facility ($1.9 million). Employee compensation was up $3.1 million primarily due to the inclusion of Taconite Harbor, annual wage increases and the inclusion of union employees in our results sharing compensation awards program. Depreciation expense increased $1.3 million primarily due to the inclusion of Taconite Harbor. MISO expenses were up $0.8 million. Pension expense increased $0.6 million due to a reduction in the discount rate. INTEREST EXPENSE was up $0.5 million, or 11 percent, from 2005 due to the inclusion of Taconite Harbor in 2006, partially offset by lower effective interest rates (5.91 percent in 2006; 6.19 percent in 2005). NONREGULATED ENERGY OPERATIONS OPERATING REVENUE was down $10.0 million, or 38 percent, from 2005 due to the absence of revenue from Taconite Harbor ($13.3 million in 2005). Effective January 1, 2006, Taconite Harbor is reported as part of the Regulated Utility segment. Coal revenue, realized under a cost-plus contract, was up $1.7 million from 2005 reflecting a 6 percent increase in the delivery price per ton due to higher coal production expenses (see operating expenses below), and a 10 percent increase in tons of coal sold in 2006. Tons of coal sold were lower in 2005 due to a plant outage at the Square Butte generating facility. OPERATING EXPENSES were down $88.2 million, or 85 percent, from 2005 reflecting the absence of a $77.9 million charge related to the assignment of the Kendall County power purchase agreement to Constellation Energy Commodities on April 1, 2005, and expenses related to Taconite Harbor ($12.3 million in 2005). Expenses related to coal operations were up $1.3 million, mainly due to increased equipment leases and fuel expenses in 2006. INTEREST EXPENSE was down $1.1 million, or 69 percent, from 2005 primarily due to the absence of Taconite Harbor in 2006. ALLETE Second Quarter 2006 Form 10-Q 28

COMPARISON OF THE QUARTERS ENDED JUNE 30, 2006 AND 2005 (CONTINUED) REAL ESTATE OPERATING REVENUE was up $5.2 million, or 52 percent, from 2005, due to the timing and mix of land sale transaction closings, and increased revenue from prior and current year land sales at our Town Center development project which are accounted for under the percentage-of-completion method. Revenue from land sales was $13.6 million in 2006 which included $2.7 million of previously deferred revenue. In 2005, revenue from land sales was $8.6 million. In 2006, 10 acres of other land were sold (54 acres in 2005). Sales at Town Center represented 186 residential units and the rights to build up to 170,695 square feet of commercial space in 2006 (397,000 commercial square feet in 2005). In 2006, revenue of $3.2 million ($7.5 million in 2005) was deferred and will be recognized on a percentage-of-completion basis as development obligations are completed. OPERATING EXPENSES were down $0.1 million, or 2 percent, from 2005 reflecting a $0.5 million decrease in the cost of real estate sold ($2.7 million in 2006; $3.2 million in 2005) due to the mix of land sold, partially offset by a $0.3 million increase in selling expenses due to higher brokerage fees. OTHER OPERATING EXPENSES were down $0.5 million, or 42 percent, from 2005, reflecting lower general and administrative expenses in 2006. OTHER INCOME (EXPENSE) reflected $1.8 million more income in 2006 primarily due to a $1.3 million increase in earnings on excess cash. INCOME TAXES For the quarter ended June 30, 2006, the effective rate for income taxes was 38.2 percent (35.3 percent benefit for the quarter ended June 30, 2005). The increase in the effective rate over last year was primarily due to the emerging technology impairment and the Kendall County capital loss recorded in April 2005. The current benefit for these items was limited to the federal benefit as the state net capital loss carryforwards from 2005 are entirely reserved. The effective rate of 38.2 percent for the quarter ended June 30, 2006, was less than the statutory rate, primarily because of investment tax credits, and deductions for Medicare health subsidies and depletion. COMPARISON OF THE SIX MONTHS ENDED JUNE 30, 2006 AND 2005 REGULATED UTILITY OPERATING REVENUE was up $23.5 million, or 8 percent, from 2005, primarily due to increased kilowatthour sales. Electric sales increased 490.7 million kilowatthours, or 8 percent, due mostly to the addition of Taconite Harbor wholesale power agreements to the Regulated Utility segment effective January 1, 2006. The majority of Taconite Harbor sales are reflected in sales to other power suppliers which were up 417.0 million kilowatthours or 69 percent, and $17.8 million. Absent the inclusion of pre-existing Taconite Harbor wholesale obligations, sales to other power suppliers were down reflecting less excess energy available for sale due to a planned outage at our Boswell Unit 4 generating facility in 2006. Electric sales to retail and municipal customers increased 73.7 million kilowatthours, or 1 percent, and $4.2 million, mainly due to strong demand from industrial customers. Revenue from electric sales to taconite customers accounted for 24 percent of consolidated operating revenue in 2006 (23 percent in 2005). Revenue from electric sales to paper and pulp mills accounted for 9 percent of consolidated operating revenue in both 2006 and 2005. 29 ALLETE Second Quarter 2006 Form 10-Q

COMPARISON OF THE SIX MONTHS ENDED JUNE 30, 2006 AND 2005 (CONTINUED) REGULATED UTILITY (CONTINUED) OPERATING EXPENSES were up $24.3 million, or 10 percent, from 2005. FUEL AND PURCHASED POWER EXPENSE. Fuel and purchased power expense was up $9.2 million from 2005, reflecting the inclusion of Taconite Harbor operations beginning in 2006 ($10.8 million) and higher prices paid for purchased power, partially offset by lower fuel expense at our generating facilities due to planned outages. OTHER OPERATING EXPENSES. In total, other operating expenses were up $15.1 million from 2005. Employee compensation was up $5.1 million primarily due to the inclusion of Taconite Harbor, annual wage increases and the inclusion of union employees in our results sharing compensation awards program. In total, plant maintenance expense increased $3.1 million from 2005 reflecting the inclusion of Taconite Harbor maintenance in 2006 ($2.2 million) and increased planned maintenance expense at Boswell Unit 4 ($2.1 million) partially offset by a decrease in maintenance expenses at Boswell Unit 3 ($2.3 million). In 2005, planned maintenance was performed at Boswell Unit 3 while the unit was down due to a cooling tower failure. Depreciation expense increased $2.6 million primarily due to the inclusion of Taconite Harbor. Pension expense increased $1.2 million due to a reduction in the discount rate. Vegetation management expenses were up $1.0 million reflecting more work performed in 2006. MISO expenses were up $0.6 million. INTEREST EXPENSE was up $1.3 million, or 15 percent, from 2005, due to the inclusion of Taconite Harbor in 2006 partially offset by lower effective interest rates (5.94 percent in 2006; 6.13 percent in 2005). NONREGULATED ENERGY OPERATIONS OPERATING REVENUE was down $21.6 million, or 40 percent, from 2005 due to the absence of revenue from Taconite Harbor ($24.7 million in 2005) and Kendall County ($3.1 million in 2005). Effective January 1, 2006, Taconite Harbor is reported as part of Regulated Utility. Kendall County operations ceased to be included with our operations effective April 1, 2005, when the Company assigned the power purchase agreement to Constellation Energy Commodities. Coal revenue, realized under a cost-plus contract, was up $2.2 million from 2005 reflecting a 10 percent increase in the delivery price per ton due to higher coal production expenses (see operating expenses below) and a 2 percent increase in tons of coal sold in 2006. Tons of coal sold were lower in 2005 due to a plant outage at the Square Butte generating facility. OPERATING EXPENSES were down $97.7 million, or 76 percent, from 2005 reflecting the absence of a $77.9 million charge related to the assignment of the Kendall County power purchase agreement to Constellation Energy Commodities on April 1, 2005, expenses related to Taconite Harbor ($19.0 million in 2005) and other expenses related to Kendall County ($6.3 million in 2005) that were incurred prior to April 1, 2005. Expenses related to coal operations were up $1.6 million mainly due to increased equipment leases and fuel expenses in 2006. INTEREST EXPENSE was down $1.9 million, or 66 percent, from 2005 primarily due to the absence of Taconite Harbor in 2006. ALLETE Second Quarter 2006 Form 10-Q 30

COMPARISON OF THE SIX MONTHS ENDED JUNE 30, 2006 AND 2005 (CONTINUED) REAL ESTATE OPERATING REVENUE was up $1.2 million, or 4 percent, from 2005, due to the timing and mix of land sale transaction closings, and increased revenue from prior and current year land sales at our Town Center development project which are accounted for under the percentage-of-completion method. Revenue from land sales was $26.1 million in 2006 which included $4.3 million of previously deferred revenue. In 2005, revenue from land sales was $25.6 million. In 2006, 466 acres of other land were sold (537 acres and 7 lots in 2005). Sales at Town Center represented 186 residential units and the rights to build up to 250,695 square feet of commercial space in 2006 (397,000 commercial square feet in 2005). The first land sales for Town Center were recorded in June 2005. In 2006, revenue of $4.0 million ($8.5 million in 2005) was deferred and will be recognized on a percentage-of-completion basis as development obligations are completed. OPERATING EXPENSES were down $1.2 million, or 13 percent, from 2005 reflecting a $1.2 million decrease in the cost of real estate sold ($4.6 million in 2006; $5.8 million in 2005), due to the mix of land sold. OTHER OTHER INCOME (EXPENSE) reflected $7.6 million more income in 2006 due to a $2.5 million increase in earnings on excess cash and the absence of emerging technology impairments. In 2005, the Company recorded $5.1 million of impairments related to two privately-held emerging technology investments. Other income (expense) also reflected equity losses related to emerging technology investments of $0.8 million in 2006 ($0.3 million in 2005). INCOME TAXES For the six months ended June 30, 2006, the effective rate for income taxes was 37.3 percent (32.5 percent benefit for the six months ended June 30, 2005). The increase in the effective rate over last year was primarily due to the emerging technology impairment and the Kendall County capital loss recorded in April 2005. The current benefit for these items was limited to the federal benefit as the state net capital loss carryforwards from 2005 are entirely reserved. The effective rate of 37.3 percent for the six months ended June 30, 2006, was less than the statutory rate primarily because of investment tax credits and deductions for Medicare health subsidies and depletion. NON-GAAP FINANCIAL MEASURES We prepare financial statements in accordance with GAAP. Along with this information, we disclose and discuss certain non-GAAP financial information in our quarterly earnings releases, on investor conference calls and during investor conferences and related events. Management believes that non-GAAP financial data supplements our GAAP financial statements by providing investors with additional information which enhances the investors' overall understanding of our financial performance and the comparability of our operating results from period to period. The presentation of this additional information is not meant to be considered in isolation or as a substitute for our results of operations prepared and presented in accordance with GAAP. As earlier mentioned, our financial results for 2005 were significantly impacted by a $50.4 million after tax, or $1.84 per share, charge due to the assignment of the Kendall County power purchase agreement to Constellation Energy Commodities. (See Note 6.) Since the Kendall County transaction significantly impacted the financial results from continuing operations in 2005, we believe that, for comparative purposes and a more accurate reflection of our ongoing operations, it is useful to present diluted earnings per share from continuing operations for each applicable period excluding the impact of this transaction. The table below reconciles actual reported diluted earnings per share from continuing operations to the adjusted results that exclude the Kendall County transaction in the respective periods. 31 ALLETE Second Quarter 2006 Form 10-Q

NON-GAAP FINANCIAL MEASURES (CONTINUED) QUARTER ENDED SIX MONTHS ENDED JUNE 30, JUNE 30, 2006 2005 2006 2005 - ----------------------------------------------------------------------------------------------------------------- DILUTED EARNINGS (LOSS) PER SHARE OF COMMON STOCK Continuing Operations - As Reported $0.49 $(1.46) $1.17 $(0.82) Add: Kendall County Charge - 1.84 - 1.84 - ----------------------------------------------------------------------------------------------------------------- Continuing Operations - As Adjusted $0.49 $ 0.38 $1.17 $1.02 - ----------------------------------------------------------------------------------------------------------------- CRITICAL ACCOUNTING POLICIES Certain accounting measurements under applicable GAAP involve management's judgment about subjective factors and estimates, the effects of which are inherently uncertain. Accounting measurements that we believe are most critical to our reported results of operations and financial condition include: impairment of long-lived assets, pension and postretirement health and life actuarial assumptions, valuation of investments and provisions for environmental remediation. These policies are reviewed with the Audit Committee of our Board of Directors on a regular basis and summarized in our 2005 Form 10-K. OUTLOOK EARNINGS GUIDANCE. We continue to expect ALLETE's earnings per share from continuing operations to grow by 15 percent to 20 percent in 2006 as outlined in our 2005 Form 10-K. The growth is expected to come from continued strong electric sales, increased real estate sales and our investment in ATC. It also reflects the absence of operating losses from Kendall County and impairments related to our emerging technology investments which impacted the Company's financial results in 2005. ENERGY. Over the next several years, we believe electric utilities will be facing the unfolding impacts of three major developments that occurred in 2005--changes in regional transmission operation, the development of rulemaking on the enactment of stricter environmental regulations and federal legislation impacting the structure and organization of the electric utility industry. We believe our energy businesses are well positioned to successfully deal with these issues and to compete successfully. Our access to and ownership of low-cost power are our greatest strengths. We anticipate that we will have ready access to sufficient capital for general business purposes. RESOURCE PLAN. In 2006, the MPUC approved our Resource Plan, which detailed our retail energy demand projections and our energy sourcing options to meet projected demand. One of the key components of the Resource Plan was the redirection of our Taconite Harbor generating facility from nonregulated energy operations to regulated utility operations effective January 1, 2006. The Taconite Harbor generation will be supplemented with a 50-MW long-term power purchase agreement with Manitoba Hydro which extends from 2009 to 2015. This agreement was executed in June 2006 and will be filed for approval with the MPUC. Expansion of our renewable generating assets to meet Minnesota's Renewable Energy Objective was also approved. The Renewable Energy Objective seeks a 10 percent supply of qualified renewable energy resources for each Minnesota utility by 2015. In April 2006, construction began on a 50-MW wind facility in North Dakota and is expected to be completed by the end of 2006. We will purchase the output from this wind facility under a 25-year power purchase agreement with an affiliate of FPL Energy, LLC. We anticipate that retail demand by customers in our service territory will increase at an average annual rate of 1.5 percent to 2019. We project a load growth of approximately 150 MW by 2010, with another 200 MW of growth anticipated by 2015. ALLETE Second Quarter 2006 Form 10-Q 32

OUTLOOK (CONTINUED) AREA AND BOSWELL 3 EMISSION REDUCTION PLANS. In May 2006, the MPUC approved our filing for cost recovery of planned expenditures to reduce emissions to meet pending federal requirements at Taconite Harbor and Laskin under the AREA plan. The approval allows Minnesota Power to recover costs for SO2, NOx and mercury emission reductions made at these facilities without a rate proceeding. Minnesota Power plans to complete installation of new equipment at the first of two Laskin units this fall, with the first of three Taconite Harbor unit installations anticipated to be completed by mid-2007. Work on all units is anticipated to be completed by the end of 2008. Cost recovery filings will be made 90 days prior to the anticipated in-service date for the equipment at each unit, with rate recovery beginning the month following the in-service date. In May 2006, we announced plans to make emission reduction investments at our Boswell Unit 3 generating unit. Plans include reductions of particulate, SO2, NOx and mercury emissions to meet pending federal and state requirements. The estimated cost for these reductions is $200 million, which the Company expects to spend from 2007 through 2010. Recovery of capital costs and incremental operating and maintenance expenses, as well as a return on investment, will commence when the project is in service. In addition, Minnesota legislation allows for a cash return on investment for construction work in progress. We plan to file for MPCA and MPUC approval of these plans and related expenditures later this year. The MPUC filing would request approval for cost recovery and returns on these investments without a rate proceeding. LARGE POWER CONTRACTS. Electric power is a key component in the production of taconite and paper, and these industries represent more than half of Minnesota Power's regulated utility electric sales. In March and April 2006, the MPUC approved new all-requirements agreements with Stora Enso Oyj's Duluth mills through August 31, 2013, and UPM-Kymmene Corporation's Blandin Paper mill in Grand Rapids through April 30, 2010. Three other long-term agreements were approved by the MPUC in 2005, extending contracts for an additional four to eight years. The extension of our electric supply contracts is an important achievement for our large power customers and Minnesota Power because it provides planning certainty for both our customers and us. MISO AND FUEL CLAUSE. On February 24, 2006, the MPUC issued an order that granted rehearing of the MISO Day 2 docket and suspended the refund obligation. The Company worked with other Minnesota utilities, the DOC and other stakeholders to prepare a joint recommendation, required by the MPUC in its February 24, 2006 order, of which costs should be recovered on a current basis through the fuel clause and which costs are more appropriately deferred for potential recovery through base rates. The joint report and recommendations were filed with the MPUC on June 23, 2006. The MPUC is requesting public comments on the report and further action on the recommendation is anticipated later in 2006. (See Note 13.) EXCELSIOR ENERGY INC. (Excelsior) has proposed to construct two 600 MW (net) coal-gasification generation units in northern Minnesota. The project is in the early development stages but may be an option for our long-term forecasted energy and capacity needs. Excelsior says the facility could be operational in 2011, but needs to obtain the necessary permits and financing. In 2003, the Minnesota legislature enacted several provisions that provide Excelsior with special considerations, including requiring utilities within the state to "consider" Excelsior before pursuing new resource additions within Minnesota. In December 2005, Excelsior filed a petition with the MPUC seeking approval of an unexecuted power purchase agreement with Xcel Energy Inc. In January 2006, Minnesota Power filed comments with the MPUC in Excelsior's proposed power purchase agreement proceeding, focusing on the importance to the state of maintaining a range of base load energy options, including multiple fuel types and generating technologies. In April 2006, the MPUC referred Excelsior's petition to an administrative law proceeding to further develop the record in the case for subsequent MPUC deliberations. Minnesota Power continues to be a participant in these proceedings, focusing its comments on energy policy and infrastructure impacts. INVESTMENT IN ATC. On May 4, 2006, the PSCW reviewed and approved the request that allows us to invest $60 million in ATC. As of June 30, 2006, we had invested $11.5 million and anticipate investing an additional $48.5 million by the end of 2006. 33 ALLETE Second Quarter 2006 Form 10-Q

OUTLOOK (CONTINUED) RATE CASE. On May 1, 2006, SWL&P filed an application with the PSCW for authority to increase retail utility rates an average of 5.2 percent and is requesting an 11.7 percent return on common equity. Cost of service studies and rate designs for all retail customer classes were filed on June 1, 2006. The PSCW has set tentative dates of August 8, 2006, for the pre-hearing conference and November 21, 2006, for the hearing. The Company anticipates that new rates will become effective in January 2007. REAL ESTATE. Progress continues on our three major planned development projects in Florida--Town Center, which will be a new downtown for Palm Coast; Palm Coast Park, which is located in northwest Palm Coast; and Ormond Crossings, which is located in Ormond Beach along Interstate 95. TOWN CENTER. We began selling property from our Town Center development project in northeast Florida in 2005. Developers who have purchased land from us have started construction activities. Since land is being sold before completion of the project infrastructure, revenue and cost of real estate sold are recorded using a percentage-of-completion method. Pending land sales under contract for properties at Town Center totaled $53.2 million at June 30, 2006. PALM COAST PARK. In May 2006, Palm Coast District issued $31.8 million of tax-exempt, special assessment bonds, the majority of which will be used to fund the construction of environmental, traffic mitigation and infrastructure improvements at Palm Coast Park. At June 30, 2006, pending land sales under contract for properties at Palm Coast Park totaled $64.3 million which included a contract for a $52.5 million sale of land that will be purchased in four phases, with closings to occur in 2007 through 2009. We have the opportunity to receive participation revenue as part of these sales contracts. ORMOND CROSSINGS. We anticipate that the Development of Regional Impact approval process will be concluded in late 2006, at which time we would receive a Development Order from the City of Ormond Beach. Engineering, design and permitting will continue through 2007. It is not anticipated that any sales will be made at Ormond Crossings until 2008. As of June 30, 2006, we had $8.1 million of deferred profit on sales of real estate, before taxes and minority interest, on our balance sheet. We expect most of this deferred profit will be reflected in income by the end of 2006. ALLETE Properties occasionally provides seller financing, and outstanding finance receivables were $7.5 million at June 30, 2006, with maturities ranging up to seven years. Outstanding finance receivables accrue interest at market-based rates. These finance receivables are collateralized by the financed properties.

LIQUIDITY AND CAPITAL RESOURCES CASH FLOW ACTIVITIES A primary goal of our strategic plan is to improve cash flow from operations. Our strategy includes growing our businesses both internally by expanding facilities, services and operations (see Capital Requirements), and externally through acquisitions. We believe our financial condition is strong, as evidenced by cash and cash equivalents and short-term investments of $183.2 million, and a debt to total capital ratio of 38 percent at June 30, 2006. OPERATING ACTIVITIES. Cash flow from operating activities was $36.4 million for the six months ended June 30, 2006 (cash flow for operating activities of $20.0 million for the six months ended June 30, 2005). Cash from operating activities was higher in 2006, primarily due to the $77.9 million Kendall County charge in 2005. Cash used for inventories was $5.4 million higher in 2006 reflecting more coal purchases in anticipation of maintenance on some coal handling equipment in the fall of 2006. Cash used for discontinued operations was higher in 2006 due to the total payment of all 2005 accrued liabilities. INVESTING ACTIVITIES. Cash flow for investing activities was $45.3 million for the six months ended June 30, 2006 (cash flow from investing activities of $58.4 million for the six months ended June 30, 2005). Cash used for investing activities was higher in 2006 than 2005, primarily due to activities within our short-term investments. In 2006, net purchases of $3.5 million were used for short-term investments, while 2005 included $87.6 million of net proceeds that were received from the sale of short-term investments. Gross proceeds from the sale of available-for-sale securities were $410.6 million in 2006 ($271.1 million in 2005) and purchases were $414.1 million ($183.5 million in 2005). Cash used for investing activities in 2006 reflected $11.5 million invested in ATC and a $12.7 million increase in additions to property, plant and equipment which vary from year to year. FINANCING ACTIVITIES. Cash flow for financing activities was $17.9 million for the six months ended June 30, 2006 ($4.3 million for the six months ended June 30, 2005). Cash used for financing activities increased in 2006 due to an additional $5.3 million of dividends paid because of more shares outstanding and an increase in the dividend rate. Cash from financing activities was $4.0 million lower in 2006, primarily due to fewer shares issued under our long-term incentive compensation plan. In 2006, we refinanced $50 million of first mortgage bonds at a lower rate. The new bonds mature in 2036. WORKING CAPITAL. Additional working capital, if and when needed, generally is provided by the sale of commercial paper. We have 0.7 million original issue shares of our common stock available for issuance through INVEST DIRECT, our direct stock purchase and dividend reinvestment plan. We have bank lines of credit aggregating $170.0 million, the majority of which expire in January 2011. In January 2006, we renewed, increased and extended a committed, syndicated, unsecured revolving credit facility with LaSalle Bank National Association, as Agent, for $150 million (Line). The Line matures on January 11, 2011. At our request and subject to certain conditions, the Line may be increased to $200 million and extended for two additional 12-month periods. We may prepay amounts outstanding under the Line in whole or in part at our discretion without premium or penalty. Additionally, we may irrevocably terminate or reduce the size of the Line prior to maturity without premium or penalty. The Line may be used for general corporate purposes, working capital and to provide liquidity in support of our commercial paper program. The amount and timing of future sales of our securities will depend upon market conditions and our specific needs. We may sell securities to meet capital requirements, to provide for the retirement or early redemption of issues of long-term debt, to reduce short-term debt and for other corporate purposes. In May 2006, Palm Coast District issued $31.8 million of tax-exempt, 5.7% Special Assessment Bonds, Series 2006, due May 1, 2037. The bonds were issued to fund a portion of the Palm Coast Park development project in Florida. Bond proceeds of $26.3 million will be used for the construction of environmental, traffic mitigation and infrastructure improvements, including utility extensions, roadways, parks, drainage, recreational facilities, landscaping and a multi-purpose trail system. The remaining funds will be used for capitalized interest, a debt service reserve fund and the costs of issuance. The bonds are payable from and secured by the revenue derived from assessments imposed, levied and collected by the Palm Coast District. The assessments represent an allocation of the costs of the improvements, including bond financing costs, to the lands within the Palm Coast District benefiting from the improvements.

LIQUIDITY AND CAPITAL RESOURCES (CONTINUED) SECURITIES In March 2001, ALLETE, ALLETE Capital II and ALLETE Capital III, jointly filed a registration statement with the SEC, pursuant to Rule 415 under the Securities Act of 1933. The registration statement, which has been declared effective by the SEC, relates to the possible issuance of a remaining aggregate amount of $387 million of securities, which may include ALLETE common stock, first mortgage bonds and other debt securities, and ALLETE Capital II and ALLETE Capital III preferred trust securities. ALLETE also previously filed a registration statement, which has been declared effective by the SEC, relating to the possible issuance of $25 million of first mortgage bonds and other debt securities. We may sell all or a portion of the remaining registered securities if warranted by market conditions and our capital requirements. Any offer and sale of the above-mentioned securities will be made only by means of a prospectus meeting the requirements of the Securities Act of 1933 and the rules and regulations thereunder. In March 2006, we issued $50 million in principal amount of First Mortgage Bonds, 5.69% Series due March 1, 2036. Proceeds were used to redeem $50 million in principal amount of First Mortgage Bonds, 7% Series due March 1, 2008. On July 5, 2006, the Collier County Industrial Development Authority issued $27.8 million of Industrial Development Variable Rate Demand Refunding Revenue Bonds Series 2006 due 2025 (Refunding Bonds) on behalf of ALLETE. Proceeds from the Refunding Bonds and internally generated funds will be used to redeem $29.1 million of outstanding Collier County Industrial Development Refunding Revenue Bonds 6.5% Series 1996 due 2025 which were called on July 5, 2006, for redemption on August 9, 2006. As a result of an early redemption premium, we will recognize a $0.6 million charge to other expense in the third quarter of 2006. Long-term debt due within one year includes $60 million of first mortgage bonds due February 2007 that cannot be redeemed prior to maturity. We intend to refinance this debt on a long-term basis. OFF-BALANCE SHEET ARRANGEMENTS Off-balance sheet arrangements are summarized in our 2005 Form 10-K, with additional disclosure discussed in Note 13 of this Form 10-Q. CAPITAL REQUIREMENTS For the six months ended June 30, 2006, capital expenditures for continuing operations totaled $35.3 million ($22.6 million in 2005). Expenditures for the six months ended June 30, 2006, included $34.5 million for Regulated Utility and $0.8 million for Nonregulated Energy Operations. Internally-generated funds were the source of funding for these expenditures. Real estate development expenditures are and will be funded with a revolving development loan and tax-exempt bonds issued by community development districts. The Town Center District issued $26.4 million of tax-exempt bonds in 2005. Approximately $21 million of the bond proceeds will be used for construction of infrastructure improvements at Town Center, with the remaining funds to be used for capitalized interest, a debt service reserve fund and costs of issuance. The Palm Coast District issued $31.8 million of tax-exempt bonds in May 2006. Bond proceeds of $26.3 million will be used for the construction of environmental, traffic mitigation and infrastructure improvements at Palm Coast Park, with the remaining funds to be used for capitalized interest, a debt service reserve fund and costs of issuance. Company expenditures related to our real estate developments in Florida increase the carrying value of our land assets, which are classified as Investments on our consolidated balance sheet. 37 ALLETE Second Quarter 2006 Form 10-Q

ENVIRONMENTAL MATTERS AND OTHER As previously discussed in our Critical Accounting Policies section, our businesses are subject to regulation of environmental matters by various federal, state and local authorities. Due to future stricter environmental requirements through legislation and/or rulemaking, we anticipate that potential expenditures for environmental matters will be material and will require significant capital investments. We are unable to predict the outcome of the issues discussed in Note 13. NEW ACCOUNTING STANDARDS New accounting standards are discussed in Note 1. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK SECURITIES INVESTMENTS AVAILABLE-FOR-SALE SECURITIES. Our available-for-sale securities portfolio consists of securities in a grantor trust established to fund certain employee benefits included in Investments, and various auction rate bonds and variable rate demand notes included in Short-Term Investments. Available-for-sale securities are recorded at fair value with unrealized gains and losses included in accumulated other comprehensive income (loss), net of tax. Unrealized losses that are other than temporary are recognized in earnings. Our short-term investments classified as available-for-sale securities are recorded at fair market value which equates to cost because the variable interest rates for these securities typically reset every 7 to 35 days. Despite the long-term nature of their stated contractual maturities, we have the ability to quickly liquidate these securities. As a result, we had no cumulative gross unrealized holding gains (losses) or gross realized gains (losses) from our short-term investments. All income generated from these short-term investments was recorded as interest income. Our available-for-sale securities portfolio had a fair value of $143.9 million at June 30, 2006 ($139.5 million at December 31, 2005) and a total unrealized after-tax gain of $2.4 million at June 30, 2006 ($2.1 million at December 31, 2005). We use the specific identification method as the basis for determining the cost of securities sold. Our policy is to review on a quarterly basis available-for-sale securities for other than temporary impairment by assessing such factors as the share price trends and the impact of overall market conditions. As a result of our periodic assessments, we did not record any impairment of available-for-sale securities for the six months ended June 30, 2006. EMERGING TECHNOLOGY PORTFOLIO. As part of our emerging technology portfolio, we have several minority investments in venture capital funds and direct investments in privately-held, start-up companies. We account for our investment in venture capital funds under the equity method and account for our direct investment in privately-held companies under the cost method based primarily on our ownership percentages. The total carrying value of our emerging technology portfolio was $9.0 million at June 30, 2006 ($9.2 million at December 31, 2005). Our policy is to review these investments quarterly for impairment by assessing such factors as continued commercial viability of products, cash flow and earnings. Any impairment would reduce the carrying value of the investment. Our basis in direct investments in privately-held companies included in the emerging technology portfolio was zero at June 30, 2006, and December 31, 2005. COMMODITY PRICE RISK Our regulated utility operations in Minnesota and Wisconsin incur costs for fuel (primarily coal), power and natural gas purchased for resale in our regulated service territories, and related transportation. Our regulated utilities' exposure to price risk for these commodities is significantly mitigated by the current ratemaking process and regulatory environment, which generally allows a fuel clause surcharge if costs are in excess of those in our last rate filing. Conversely, costs below those in our last rate filing result in a rate credit. We seek to prudently manage our customers' exposure to price risk by entering into contracts of various durations and terms for the purchase of coal and power (in Minnesota), power and natural gas (in Wisconsin), and related transportation costs. ALLETE Second Quarter 2006 Form 10-Q 38

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK (CONTINUED) POWER MARKETING Our power marketing activities consist of: (1) purchasing energy in the wholesale market for resale in our regulated service territories when retail energy requirements exceed generation output; and (2) selling excess available generation and purchased power. From time to time, our utility operations may have excess generation that is temporarily not required by retail and municipal customers in our regulated service territory. We actively sell this generation to the wholesale market to optimize the value of our generating facilities. This generation is generally sold in the MISO market at market prices. Approximately 200 MW of generation from our Taconite Harbor facility in northern Minnesota has been sold through various long-term capacity and energy contracts. Long-term, we have entered into two capacity and energy sales contracts totaling 175 MW (201 MW including a 15 percent reserve), which were effective May 1, 2005, and expire on April 30, 2010. Both contracts contain fixed monthly capacity charges and fixed minimum energy charges. One contract provides for an annual escalator to the energy charge based on increases in our cost of coal, subject to a small minimum annual escalation. The other contract provides that the energy charge will be the greater of a fixed minimum charge or an amount based on the variable production cost of a combined-cycle, natural gas unit. Our exposure in the event of a full or partial outage at our Taconite Harbor facility is significantly limited under both contracts. When the buyer is notified at least two months prior to an outage, there is no exposure. Outages with less than two months' notice are subject to an annual duration limitation typical of this type of contract. We also have a 50-MW capacity and energy sales contract that extends through April 2008, with formula pricing based on variable production cost of a combustion-turbine, natural gas unit. ITEM 4. CONTROLS AND PROCEDURES We maintain a system of controls and procedures designed to provide reasonable assurance as to the reliability of the financial statements and other disclosures included in this report, as well as to safeguard assets from unauthorized use or disposition. We evaluated the effectiveness of the design and operation of our disclosure controls and procedures under the supervision and with the participation of management, including our chief executive officer and chief financial officer, as of the end of the period covered by this Form 10-Q. Based upon that evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures are effective. While we continue to enhance our internal control over financial reporting, there has been no change in our internal control over financial reporting that occurred during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 39 ALLETE Second Quarter 2006 Form 10-Q

ITEM 5. OTHER INFORMATION Reference is made to our 2005 Form 10-K for background information on the following updates. Unless otherwise indicated, cited references are to our 2005 Form 10-K. Ref. Page 12 - First, Second and Third Full Paragraphs In May 2006, the MPUC approved our filing for cost recovery of planned expenditures to reduce emissions to meet pending federal requirements at Taconite Harbor and Laskin under the AREA plan. The approval allows Minnesota Power to recover costs for SO2, NOx and mercury emission reductions made at these facilities without a rate proceeding. Minnesota Power plans to complete installation of new equipment at the first of two Laskin units this fall, with the first of three Taconite Harbor unit installations anticipated to be completed by mid-2007. Work on all units is anticipated to be completed by the end of 2008. Cost recovery filings will be made 90 days prior to the anticipated in-service date for the equipment at each unit, with rate recovery beginning in the month following the in-service date. Ref. Page 20 - Sixth Full Paragraph On June 16, 2006, Minnesota Power filed an application with the MPCA for a variance from a clarified ash pond discharge standard for mercury included in its National Pollutant Discharge Elimination System (NPDES) permit for Laskin. The variance requests an extension for Laskin to meet mercury discharge requirements which become effective March 23, 2007, as set forth in Laskin's NPDES permit issued by the MPCA in May 2005. Currently there is no feasible technology available that would enable Laskin to meet the March 23, 2007 deadline to lower the mercury in its wastewater discharge. The Company is actively researching and testing treatment technology options, but is unable to predict the outcome of this matter. Ref. Page 20 - Seventh Full Paragraph Minnesota Power, the Fond du Lac Band of Lake Superior Chippewa and the U.S. Department of Interior (DOI) reached a settlement agreement to resolve each party's respective appeals of the St. Louis River Project hydroelectric license. In December 2004, Minnesota Power filed an application for an amendment to the St. Louis River Project license incorporating the settlement agreement. On June 22, 2006, the FERC issued an order modifying and approving Minnesota Power's application to amend the license consistent with the settlement agreement. The FERC declined a request by the DOI to vacate portions of the original license order as part of the license amendment process. The order by the FERC, otherwise adopts the material provisions of the settlement as part of the amended project license. The order became final and non-appealable on July 22, 2006. 41 ALLETE Second Quarter 2006 Form 10-Q

The Company shall be obligated to repay the loan from the proceeds of the Series 2006 Bonds in full, and the Trustee on behalf of the Issuer shall call for redemption and prepayment all of the outstanding Series 2006 Bonds on the earliest practicable date, upon written notice to the Company by the Trustee of the occurrence of a Determination of Taxability, as provided in Section 301(b) of the Indenture. The prepayment of the loan required by the preceding paragraph, which shall be deposited on or prior to the redemption date, shall be a sum sufficient, together with other funds deposited with the Trustee and available for such purpose, to redeem all of the outstanding Series 2006 Bonds at a price equal to the principal amount thereof with interest accrued to the date of redemption, and to pay the Taxability Premium and, if no Bonds shall thereafter remain outstanding, to pay all reasonable and necessary fees and expenses of the Trustee and any Paying Agent, and all other liabilities of the Company, accrued and to accrue under this Agreement through the redemption date. The Company acknowledges and agrees that the Taxability Premium shall be owing with respect to Series 2006 Bonds outstanding during the Taxable Period but not outstanding on the redemption date prescribed by Section 301(b) of the Indenture and that the payment of the Taxability Premium will not be paid from a draw on the Letter of Credit. To evidence and secure its obligation to pay the Taxability Premium, the Company -14-

agrees to deliver to the Issuer the Note, contemporaneously with the issuance of the Series 2006 Bonds. ARTICLE VI SPECIAL COVENANTS OF THE COMPANY Section 6.01. MAINTENANCE OF CORPORATE EXISTENCE. Except as otherwise permitted in the First Mortgage, the Company covenants that it will maintain its corporate existence and qualification to do business in the State, will not dissolve or otherwise dispose of all or substantially all its assets and will not consolidate with or merge into or with another corporation or permit one or more other corporations to consolidate with or merge into it. In the event of any such acquisition of its assets, or merger or consolidation, as permitted by the First Mortgage, the acquirer of its assets or the corporation with which it shall consolidate or into which it shall merge shall assume in writing all of the obligations of the Company under this Agreement.

Section 6.03. INDEMNIFICATION; PERSONAL LIABILITY WAIVED. The Company agrees to indemnify and hold the Issuer, the Governmental Units and the Trustee harmless from, any liability for any loss or damage to property or any injury to or death of any person that may be occasioned by any cause whatsoever pertaining to the Refinanced Facilities.

Under this Section 6.03, the Company shall also be deemed to release, indemnify and agree to hold harmless each employee, official, officer or agent of the Issuer or a Governmental Unit to the same extent as the Issuer or the Governmental Unit. If any claim of the type described in this Section 6.03 is asserted against the Issuer, a Governmental Unit or the Trustee or any employee, official, officer or agent of any thereof, the Issuer, the Governmental Unit or the Trustee, as the case may be, agrees to give prompt written notice to the Company and the Company shall have authority to assume the defense thereof, with full power to litigate, compromise or settle the same in its sole discretion; it being understood that the Issuer, any Governmental Unit and the Trustee will not settle or consent to the settlement of the same without the consent of the Company. -15-

Notwithstanding anything to the contrary contained herein or in any of the Bonds, or the Indenture, or in any other instrument or document executed by or on behalf of the Issuer or the Trustee in connection herewith, no stipulation, covenant, agreement or obligation contained herein or therein shall be deemed or constructed to be a stipulation, covenant, agreement, or obligation of any present or future member, officer, employee or agent of the Issuer or the Trustee, or of any incorporator, member, director, trustee, officer, employee or agent of any successor to the Issuer or the Trustee, in any such person's individual capacity, and no such person, in his individual capacity, shall be liable personally for any breach or non-observance of or for any failure to perform, fulfill or comply with any such stipulations, covenants, agreements or obligations, nor shall any recourse be had for the payment of the principal of, premium, if any, or interest on or Purchase Price with respect to any of the Bonds or for any claim based thereon or on any such stipulation, covenant, agreement, or obligation, against any such person, in his individual capacity, either directly or through the Issuer and the Trustee or any successor to the Issuer or the Trustee, under any rule of law or equity, statute or constitution or by the enforcement of any assessment or penalty or otherwise, and all such liability of any such person, in his individual capacity, is hereby expressly waived and released, except only for liability that results from intentional acts of any such individual. The covenants in this Section 6.03 shall survive the payment of the Bonds, termination of the other provisions of this Agreement or the Interlocal Agreement and the discharge of the other obligations of the Company hereunder. Section 6.04. ADDITIONAL PAYMENTS. In addition to any other payments required hereunder, the Company will pay the following amounts to the following persons: (1) to the Trustee, when due, all reasonable fees and expenses of the Trustee for services rendered under the Indenture and all reasonable fees and expenses of the Tender Agent, Paying Agents, counsel, accountants, engineers and others incurred in the performance on request of the Trustee of services under the Indenture for which the Trustee and such other Persons are entitled to payment or reimbursement, but the Company may, without creating a default hereunder, contest in good faith the reasonableness of any such services, fees or expenses other than the Trustee's, the Tender Agent's and any Paying Agent's fees for ordinary services as set forth in the Indenture; and (2) to the Issuer and each Governmental Unit, all reasonable and necessary expenses incurred by the Issuer or the Governmental Unit, with the prior written approval of the Company, with respect to this Agreement, the Interlocal Agreement, the Indenture and any transaction or event contemplated by this Agreement, the Interlocal Agreement or by the Indenture and which are not otherwise required to be paid by the Company under the terms of this Agreement. In the event the Company should fail to make any of the payments required by this Section 6.04, the item in default shall continue as an obligation of the Company until the amount in default shall have been fully paid, and the Company will pay the same with interest thereon at a rate per annum equal to one percent above the prime or reference rate from time to time publicly announced by and in effect for the largest commercial bank, as measured by assets, in -16-

the Ninth Federal Reserve District (with each change in such prime or reference rate resulting in a corresponding change in the rate to be paid hereunder), or, if such rate or rates shall exceed the maximum rate then permitted by law, at the maximum rate permitted by law; provided that, with the exception of the Trustee's and any Paying Agent's fees, interest shall not accrue on such obligation until written notice has been given to the Company that such payment is due. Section 6.05. ASSURANCE OF TAX EXEMPTION. (a) In order to ensure that the interest on the Series 2006 Bonds shall, at all times, be excludable from gross income for purposes of federal income taxation (other than by operation of Section 147(a) of the Code), the Company represents, covenants and agrees with the Issuer, the Trustee and all Owners of the Series 2006 Bonds that: (1) The information and estimates heretofore furnished to the Issuer and Bond Counsel by the Company and contained in the Certificate as to Refinanced Facilities delivered in connection with the issuance of the Series 2006 Bonds and in the Tax Compliance Agreement with respect to the nature and use of the Refinanced Facilities and the expenditure of the proceeds of the Prior Bonds and the Refunded Bonds are true and correct and do not omit any statement, the omission of which would render any of the statements made therein misleading in the circumstances in which they are made. The Company has no reason to believe that the Tax Certificates delivered by the City of Marco Island, Florida and the City of Deltona, Florida, are not true and correct in all material respects or omit any statement, the omission of which would render any of the statements made therein misleading in the circumstances in which they are made. (2) At least 95% of the proceeds of each series of the Prior Bonds (including transferred proceeds of the Series 1996 Bonds), including any investment earnings thereon, has been used for the payment of costs of "facilities for the furnishing of water" and "sewage facilities" within the meaning of Section 142(a)(4) and (5) and Section 142(e) of the Code and applicable Treasury Regulations, as applicable. (3) At least 95% of the proceeds of each series of the Prior Bonds (including transferred proceeds of the Series 1996 Bonds), including any investment earnings thereon, has been used to provide either land or property of a character subject to the allowance for depreciation under Section 167 of the Code and all amounts paid from the proceeds of the Prior Bonds were, for federal income tax purposes, chargeable to the capital account of an Affiliate of the Company with respect to the Refinanced Facilities or would have been so chargeable either with a proper election by the Affiliate (for example, under Section 266 of the Code) or but for a proper election by the Affiliate to deduct such amounts. (4) The Company will not use the proceeds of the Series 2006 Bonds or any other moneys in such a manner as to cause the Series 2006 Bonds to be "arbitrage bonds" within the meaning of Section 148 of the Code. (5) The Company will not take any action, or permit any action (which is within its control) to be taken, which would otherwise cause the interest on the Series 2006 Bonds to become includable in gross income for purposes of federal income -17-

taxation in the hands of the owners thereof (other than by operation of Section 147(a) of the Code). (6) The Company will comply with any restrictions on the investment of moneys set forth in the Tax Compliance Agreement in respect of the Series 2006 Bonds. (7) The Company will take no action, nor permit any action to be taken, which would render inaccurate or incorrect any of the representations or warranties made in this Section 6.05(a) or any of the representations or certifications otherwise given by or on behalf of the Company or Southern States Utilities, Inc. in connection with the issuance of the Prior Bonds, the Refunded Bonds or the Series 2006 Bonds. (8) The Company will comply with and fulfill, or cause to be complied with and fulfilled, all other requirements and conditions of the Code and regulations and rulings issued pursuant thereto relating to the Refinanced Facilities and the operation thereof to the end that the interest on the Series 2006 Bonds shall at all times be excludable from gross income for purposes of federal income taxation in the hands of the owners thereof (other than by operation of Section 147(a) of the Code). (9) The weighted average maturity of the Series 2006 Bonds does not exceed the weighted average maturity of the Refunded Bonds, determined as of the date of issuance of the Series 2006 Bonds (all within the meaning of Section 147(b) of the Code). (10) None of the proceeds of the Prior Bonds, the Refunded Bonds or the Series 2006 Bonds has been or will be used to provide an airplane, skybox or other private luxury box, health club facility, or store the principal business of which is the sale of alcoholic beverages for consumption off premises. (11) No obligations which are private activity bonds under Section 141 of the Code but bear interest which is excludable from gross income for purposes of federal income taxation, are sold at substantially the same time as the Series 2006 Bonds pursuant to the same plan of marketing which are payable in whole or in part by the Company or otherwise have with the Series 2006 Bonds any common or pooled security for the payment of debt service thereon. (12) Not more than 25% of the proceeds of each series of the Prior Bonds or Refunded Bonds has been or will be used (directly or indirectly) to acquire land (or an interest therein) and none of the proceeds of the Prior Bonds or Refunded Bonds has been or will be used for the acquisition of any property (or an interest therein) unless the first use of such property was pursuant to such acquisition. (13) The Refinanced Facilities do not include any property to be sold or any property to be affixed to or consumed in the production of property for sale, or any housing facility to be rented or used as a permanent residence. (14) None of the proceeds of the Series 2006 Bonds will be used to pay "issuance costs" of the Bonds within the meaning of Section 147(g) of the Code. -18-

(b) The Issuer and the Company covenant and certify to each other and to and for the benefit of the Owners of the Bonds that no use will be made of the proceeds of the Bonds or any other moneys, which would cause any Bonds to be arbitrage bonds within the meaning of Section 148 of the Code. Pursuant to such covenant, the Issuer and the Company jointly and severally obligate themselves to comply throughout the term of the issue of the Bonds with the requirements of Section 148 of the Code. The Issuer shall be conclusively presumed to have conformed to the requirements of this Section 6.05(b) to the extent it relies upon an Opinion of Bond Counsel. The Company recognizes that the exemption from federal income taxation of the interest to be paid on the Series 2006 Bonds is dependent upon compliance with the provisions of Section 148 of the Code. The Company represents to and covenants with the Issuer, the Trustee and each Owner of Bonds that: (1) If all "gross proceeds" (as defined in Section 148(f)(6)(B) of the Code) of the Series 2006 Bonds are not expended for the payment of principal of and interest on Refunded Bonds by the date which is 90 days after the date of issue of the Series 2006 Bonds, or if, notwithstanding that all gross proceeds are so expended by such date, gross proceeds arise at some later date, then the Company shall make the determinations and take the actions hereinafter required by this Section 6.05(e), on behalf of, and as agent for, the Issuer, and shall rebate to the United States, not later than 60 days after each installment computation date, an amount which ensures that at least 90% of the Rebate Amount (as hereinafter defined) at the time of such payment will have been paid to the United States, and within 60 days after the final computation date, an amount sufficient to pay the remaining balance of the Rebate Amount, all in the manner and as required by Section 148(f) of the Code. As used herein, "Rebate Amount" means the amount described in Section 148(f)(2) of the Code, computed in accordance with the provisions of said Section 148(f)(2) and the regulations now or hereafter promulgated thereunder, including Treasury Regulations, Sections 1.148-0 through 1.148-11 and 1.150-1. (2) The Company shall determine the Rebate Amount within 30 days after the close of each bond year and upon payment or redemption of all principal of the Series 2006 Bonds, and shall furnish the Issuer and the Trustee upon each determination with a certificate of a Company Representative verifying such determination and with any supporting documentation required to calculate or evidence the Rebate Amount in accordance with the Code and applicable regulations. The Company shall retain records of such determinations until six years after final payment or redemption of principal of the Series 2006 Bonds. Upon each such determination, the Company shall set aside, or cause to be set aside, the Rebate Amount so determined, and shall separately account for, or cause to be separately accounted for, the earnings from the investment thereof, and such earnings shall become part of the Rebate Amount. (c) The Company covenants and agrees that it will perform its covenants and agreements relating to the Refunded Bonds in respect of the calculation and payment to the United States of any rebatable arbitrage in respect of the Refunded Bonds under Section 148(f) of the Code, within 60 days after the date of final payment of the Refunded Bonds, so as to preserve the tax exemption of interest on the Refunded Bonds. -19-

(d) The provisions of this Section 6.05 shall survive the retirement and payment of the Bonds and the discharge of the Issuer's and the Company's other obligations hereunder. (e) Notwithstanding anything in this Agreement or the Indenture to the contrary, the provisions of this Section 6.05 may be amended by an instrument signed by the Issuer and the Company and delivered to the Trustee, accompanied by an Opinion of Bond Counsel stating in effect that the provisions of this Section 6.05, as so amended, if complied with by the Company, will not adversely affect the tax exclusion from gross income of interest on any Series 2006 Bond for purposes of federal income taxation. Section 6.06. REDEMPTION OF REFUNDED BONDS; PAYMENT OF COSTS OF ISSUANCE. The Company covenants and agrees with the Issuer that it will cause the Refunded Bonds to be paid and discharged on or prior to the 90th day after the date of issuance of the Series 2006 Bonds. The Company also covenants and agrees to provide any moneys required for the payment and discharge of the Refunded Bonds on or prior to the date on which they are called for redemption. The Company further agrees that it will pay all reasonable Costs of Issuance promptly when due. It is acknowledged and agreed that $6,000,000 in principal amount of the Series 1996 Bonds do not constitute Refunded Bonds and will remain outstanding under the Refunded Bonds Indenture. Section 6.07. LETTER OF CREDIT; ALTERNATE LETTER OF CREDIT. (a) The Company shall provide for the delivery of the original Letter of Credit to the Trustee simultaneously with the initial issuance and delivery of the Series 2006 Bonds. The Company hereby authorizes and directs the Trustee to submit draws under the Letter of Credit in accordance with the provisions of the Indenture to the extent necessary to pay the Purchase Price with respect to the Bonds as and when due and, if the Letter of Credit is not a Liquidity Facility, the principal of and interest on the Bonds when due. (b) The Company shall cause the Letter of Credit to be maintained in full force and effect (except when not required pursuant to Article V of the Indenture) in an amount equal to the principal amount of the Outstanding Bonds plus the amount required for payment of interest and premium, if any, thereon as required by Section 503 of the Indenture, until all of the Bonds have been paid in full or their payment provided for in accordance with Article XI of the Indenture. When required by Article V of the Indenture, the Company will exercise its best efforts to extend the term of the Letter of Credit currently in effect or to cause an Alternate Letter of Credit to be delivered by the Credit Bank to the Trustee not less than 30 days prior to the termination date of the Letter of Credit then in effect pursuant to the provisions of Section 502 of the Indenture. The Company may at any time, subject to any applicable provisions of the Credit Agreement, arrange for the substitution of an Alternate Letter of Credit for an existing Letter of Credit, and the Trustee is to accept any Alternate Letter of Credit, subject to the limitations and upon the conditions contained in Section 502 of the Indenture. (c) The Company shall give written notice to the Issuer, the Trustee, the Tender Agent and each Rating Service maintaining a rating on the Bonds not less than 60 days prior to the expiration or termination date of the Letter of Credit then in effect, specifying that the Company intends to replace the existing Letter of Credit with an Alternate Letter of Credit on or -20-

before the expiration of the Letter of Credit then in effect, except when a Letter of Credit is not required under Article V of the Indenture. (d) Except when not required under Article V of the Indenture, the Company shall cause to be delivered to the Trustee not less than 30 days prior to the expiration or termination date of the existing Letter of Credit (1) an Alternate Letter of Credit that is effective as of a date on or prior to the date of expiration of the then existing Letter of Credit, and (2) written notice from each Rating Service maintaining a rating on the Bonds stating whether the substitution of such Alternate Letter of Credit will result in a reduction or withdrawal of the rating then in effect on the Bonds. The Bonds will be subject to mandatory tender as provided in the Indenture, if either a Liquidity Facility is being provided in substitution for a Letter of Credit that is not a Liquidity Facility or such written notice from any Rating Service then having a rating in effect for the Bonds states that the replacement of the current Letter of Credit with the proposed Alternate Letter of Credit will result in a withdrawal or reduction of the Rating Service's then current rating for the Bonds. (e) Except when a Letter of Credit is not required under Article V of the Indenture, when the Bonds are in a Daily, Weekly, Commercial Paper or Long-Term Rate Period, the Company shall exercise its best efforts to arrange for the delivery to the Trustee of an Alternate Letter of Credit to replace any Letter of Credit then in effect upon the expiration thereof prior to the end of any such rate period or upon the occurrence of any of the following events or circumstances: (1) If the Credit Bank has rescinded, terminated or repudiated the Letter of Credit contrary to the terms of the Letter of Credit, or the Letter of Credit for any reason ceases to be valid and binding on the Credit Bank or is declared to be null and void, or the validity or enforceability of any provision of the Letter of Credit is denied by the Credit Bank or any governmental agency or authority, or the Credit Bank is denying further liability or obligation under the Letter of Credit, in all of the above cases contrary to the terms of the Letter of Credit. (2) If the Credit Bank shall not extend the stated termination date with respect to the current Letter of Credit then in effect, but the term of such Alternate Letter of Credit need not (but may) begin prior to the stated termination date of the current Letter of Credit then in effect. The Company shall not terminate the current Letter of Credit and Credit Agreement until the term of the Alternate Letter of Credit has begun. (3) Receipt by the Trustee of written notice from the Credit Bank that an "event of default" as such term is defined in the Credit Agreement has occurred and is continuing under the Credit Agreement and a direction to effect a mandatory tender of the Bonds. (4) The Credit Bank has wrongfully failed to honor a properly presented draw made under and in compliance with the terms of the Letter of Credit which failure has not been cured. -21-

(5) Receipt by the Trustee, within 10 days following a drawing under the Letter of Credit to pay interest on the Bonds on the due date, of written notice from the Credit Bank that the Credit Bank has not been reimbursed for such drawing on the Letter of Credit and the amount for such drawing has not been reinstated and directing mandatory tender of the Bonds. (f) On or prior to the effective date of any Alternate Letter of Credit, the Company shall furnish to the Issuer and the Trustee: (1) an Opinion of Counsel stating that delivery of such Alternate Letter of Credit to the Trustee is authorized under this Indenture, and complies with the terms hereof, (2) an Opinion of Counsel from counsel to the Credit Bank issuing such Alternate Letter of Credit to the effect that the Alternate Letter of Credit is a valid and binding obligation of such issuer or provider, enforceable in accordance with its terms, subject to customary exceptions relating to bankruptcy and insolvency, and (3) an Opinion of Bond Counsel, which shall also be addressed and delivered to the Issuer, stating that the delivery of such Alternate Letter of Credit to the Trustee is authorized under the Indenture and complies with the terms thereof and does not adversely affect the tax-exempt status of the interest on the Bonds. Section 6.08. CONTINUING DISCLOSURE. The Company represents that, so long as the Bonds are in a Daily Rate Period or a Weekly Rate Period, the Bonds are exempt from the continuing disclosure requirements of Rule 15c2-12 promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934 (17 C.F.R. ss. 240.15c2-12) (as in effect and interpreted from time to time, the "Rule"), but acknowledges that when the Bonds are in a Commercial Paper Rate Period, a Long-Term Rate Period or the Fixed Rate Period, the Bonds are subject to the continuing disclosure requirements of the Rule. The Company covenants and agrees that, when necessary to comply with the Rule, it will execute and deliver a continuing disclosure agreement, or a similar undertaking which in the Opinion of Counsel will satisfy the Rule, and the Company hereby covenants and agrees to observe and perform the covenants and agreements contained therein, unless amended or terminated in accordance with the provisions thereof, for the benefit of the Owners or beneficial owners from time to time of the Outstanding Bonds as therein provided. Notwithstanding any other provision of this Agreement, failure of the Company to comply with the continuing disclosure agreement or similar undertaking shall not be considered an event of default under this Agreement or under Indenture. ARTICLE VII ASSIGNMENT Section 7.01. CONDITIONS. The Company's interest in this Agreement may be assigned in whole or in part, provided, however, that no assignment shall cause the Company to breach any of the covenants contained in Section 6.05 hereof or any of the representations or warranties contained in Section 2.02 hereof, or otherwise cause the interest payable on any Bonds to become includable in gross income for purposes of federal income taxation (other than by operation of Section 147(a) of the Code), nor relieve the Company from primary liability for its obligation to make the loan payments required by Section 3.02 hereof or other payments under Section 3.03 hereof or for any other of its obligations hereunder. Upon any such assignment or conveyance of assets, merger or consolidation permitted under Section 6.01, the Company shall -22-

give prompt written notice to the Issuer and the Volusia County Industrial Development Authority. Section 7.02. INSTRUMENT FURNISHED TO TRUSTEE. The Company shall, within 15 days after the delivery thereof, furnish to the Issuer and the Trustee a true and complete copy of the agreements or other documents effectuating any such assignment. Section 7.03. LIMITATION. So long as any Bonds are Outstanding, this Agreement shall not be assigned, except as provided in this Article VII or in Section 6.01 hereof. ARTICLE VIII EVENTS OF DEFAULT AND REMEDIES Section 8.01. EVENTS OF DEFAULT. Any one or more of the following events is an Event or Default under this Agreement: (1) if the Company shall fail to pay any amounts due under Sections 3.02 or 3.03 hereof when due; (2) if the Company shall fail to observe its covenants in Section 6.05 or 6.07 hereof; (3) if the Company shall fail to observe and perform, for reasons other than Force Majeure (as set forth in Section 8.02 hereof), any other covenant, condition or agreement on its part under this Agreement for a period of 60 days after written notice, specifying such default and requesting that it be remedied, is given to the Company by the Trustee, unless the Trustee shall agree in writing to an extension of such time prior to its expiration, or for such longer period as may be reasonably necessary to remedy such default, provided that the Company is proceeding with reasonable diligence to remedy the same; (4) if the Company shall (a) admit in writing its inability to pay its debts generally as they become due; (b) consent to the appointment of a custodian (as that terms is defined in the Federal Bankruptcy Code) for, or assignment to a custodian of, the whole or any substantial part of the Company's property, or fail to stay, set aside or vacate within 90 days from the date of entry thereof any order or decree entered by a court of competent jurisdiction ordering such appointment or assignment; or (c) commence any proceeding or file a petition under the provisions of the Federal Bankruptcy Code for liquidation, reorganization or adjustment of debts, or under any insolvency law or other statute or law providing for the modification or adjustment of the rights of creditors or fail to stay, set aside or vacate within 90 days from the date of entry thereof any order or decree entered -23-

by a court of competent jurisdiction pursuant to any involuntary proceeding, whether under Federal or state law, providing for liquidation or reorganization of the Company or modification or adjustment of the rights of creditors; or (5) if, as a result of an "event of default" under the First Mortgage, the principal of the First Mortgage Bonds of the Company issued thereunder has been declared or has become due. Section 8.02. FORCE MAJEURE. The provisions of Section 8.01(3) hereof are subject to the following limitations: If by reason of acts of God, strikes, lockouts or other industrial disturbances, acts of public enemies, orders of any kind of the Government of the United States or of the State, or any department, agency, political subdivision, court or official of either of them, or any civil or military authority, insurrections, riots, epidemics, landslides, lightning, earthquakes, fires, hurricanes, tornados, storms, floods, washouts, droughts, arrests, restraint of government and people, civil disturbances, explosions, breakage or accident to machinery, partial or entire failure of utilities, or any cause or event not reasonably within the control of the Company, the Company is unable in whole or in part to carry out any one or more of its agreements or obligations contained in this Agreement, other than its obligations contained in Sections 3.02, 3.03, 6.01, 6.03, 6.05, 6.07 and 6.08 hereof, the Company shall not be deemed in default by reason of not carrying out said agreement or agreements or performing said obligation or obligations during the continuance of such inability. The Company agrees, however, to use its best efforts to remedy with all reasonable dispatch the cause or causes preventing it from carrying out its agreements; provided that the settlement of strikes, lockouts and other industrial disturbances shall be entirely within the discretion of the Company, and the Company shall not be required to make settlement of strikes, lockouts and other industrial disturbances by acceding to the demands of the opposing party or parties when such course is, in the judgment of the Company, unfavorable to the Company. Section 8.03. REMEDIES. Whenever any Event of Default shall have happened and be subsisting, the Issuer may, with the prior written consent of the Trustee and with notice in writing to the Company, declare the remaining principal balance of the loan payable under Section 3.02 and any other amounts due hereunder (being an amount equal to that necessary to pay in full all Outstanding Bonds, assuming acceleration of the Bonds under the Indenture and to pay all other indebtedness thereunder) to be immediately due and payable, whereupon the same shall become immediately due and payable by the Company; and, in the event the Company does not, within three business days thereafter, deposit with the Trustee an amount sufficient to satisfy its obligations under the preceding clause, then the Issuer, or the Trustee on behalf of the Issuer, may take whatever action at law or in equity may appear necessary or appropriate to collect the balance then due, or to enforce performance and observance of any obligation, agreement or covenant of the Company under this Agreement. Notwithstanding the foregoing sentence, no notice of acceleration shall be given or effective unless the Credit Bank which is the issuer of a Letter of Credit other than a Liquidity Facility has given the Trustee its written consent to the giving of the notice of acceleration. Any amounts collected pursuant to action taken under this Section 8.03 shall be paid into the Debt Service Fund and applied in accordance with the provisions of the Indenture. -24-

Section 8.04. NO REMEDY EXCLUSIVE. No remedy conferred upon or reserved to the Issuer by this Agreement is intended to be exclusive of any other available remedy or remedies, but each and every such remedy shall be cumulative and shall be in addition to every other remedy given under this Agreement or now or hereafter existing at law or in equity or by statute. No delay or omission to exercise any right or power accruing upon any default shall impair any such right or power or shall be construed to be a waiver thereof, but any such right or power may be exercised from time to time and as often as may be deemed expedient. In order to entitle the Issuer to exercise any remedy reserved to it in this Article, it shall not be necessary to give any notice, other than such notice as may be herein expressly required. Section 8.05. REIMBURSEMENT OF ATTORNEYS' FEES. If the Company shall default under any of the provisions of this Agreement and the Issuer or the Trustee shall employ attorneys or incur other reasonable expenses for the collection of payments due hereunder or for the enforcement of performance or observance of any obligation or agreement on the part of the Company contained in this Agreement, the Company will on demand therefor reimburse the Issuer or the Trustee, as the case may be, for the reasonable fees of such attorneys and such other reasonable expenses so incurred. Section 8.06. WAIVER OF BREACH; EXERCISE OF RIGHTS BY TRUSTEE. In the event any obligation created by this Agreement shall be breached by either of the parties and such breach shall thereafter be waived by the other party, such waiver shall be limited to the particular breach so waived and shall not be deemed to waive any other breach hereunder. In view of the pledge of and grant of a security interest in the Issuer's rights in and under this Agreement to the Trustee under the Indenture, the Issuer shall have no power to waive any default hereunder by the Company without the consent of the Trustee, and the Trustee may exercise any of the rights of the Issuer hereunder. Section 8.07. TRUSTEE'S EXERCISE OF THE ISSUER'S REMEDIES. Whenever any Event of Default shall have happened and be subsisting, the Trustee may, but except as otherwise provided in the Indenture shall not be obliged to, exercise any or all of the rights of the Issuer under this Article VIII, upon notice as required of the Issuer unless the Issuer has already given the required notice.

If the Company fails to make any such payment when due, the unpaid amount thereof shall bear interest until paid by the Company at the rate specified in Section 2.13. (b) OTHER L/C DISBURSEMENTS. Upon the occurrence of any L/C Disbursement not described in subsection (a), the Issuing Bank may request payment in the amount of such L/C Disbursement from the Participating Banks as provided in subsection (c). The amount so paid by each Participating Bank shall constitute a loan (a "DRAWING LOAN") to the Company by such Participating Bank, the proceeds of which Drawing Loan shall be remitted by the Participating Banks to the Administrative Agent and applied by the -9-

Administrative Agent or the Issuing Bank to the payment of the corresponding Reimbursement Obligation. Each Drawing Loan shall be due and payable on demand and shall bear interest on the unpaid principal amount thereof from the date such Drawing Loan is made until it is paid in full, at a rate per annum equal to the Unreimbursed Drawing Rate. (c) PAYMENTS BY PARTICIPATING BANKS. Upon any L/C Disbursement described in subsection (b), the Issuing Bank, directly or through the Administrative Agent, shall (and, at any time following any other L/C Disbursement, may) give each Participating Bank prompt notice (orally or in writing) of such L/C Disbursement, specifying (a) the amount of such L/C Disbursement, (b) the date such L/C Disbursement was or is to be made and (c) such Participating Bank's PRO RATA share of the amount of such L/C Disbursement (determined on the basis of such Participating Bank's Commitment Percentage). If so requested, each Participating Bank shall pay to the Administrative Agent, for the account of the Issuing Bank, an amount equal to such Participating Bank's Commitment Percentage of such L/C Disbursement, such payment to be made not later than 3:00 p.m. on the date on which such L/C Disbursement is made or to be made (if such Participating Bank was notified at or prior to 1:00 p.m. on such date) or on the next Business Day (if such Participating Bank was notified after such time). Each Participating Bank's obligation to make each such payment, and the right of the Administrative Agent and the Issuing Bank to receive the same, are absolute and unconditional and shall not be affected by any circumstance whatsoever, including (without limiting the effect of the foregoing or of Section 2.4) the occurrence or continuance of a Potential Default or Event of Default or the failure of any other Participating Bank to make any payment under this Section, and each Participating Bank further agrees that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Participating Bank shall indemnify and hold harmless the Administrative Agent and the Issuing Bank from and against any and all losses, liabilities (including, without limitation, liabilities for penalties), actions, suits, judgments, demands, costs and expenses (including reasonable attorneys' fees) resulting from any failure of such Participating Bank to provide, or from any delay in providing, the Administrative Agent with such Participating Bank's Commitment Percentage of such L/C Disbursement in accordance with the provisions of this Section, but no Participating Bank shall be so liable for any such failure on the part of any other Participating Bank. (d) If any amount required to be paid by any Participating Bank to the Administrative Agent pursuant to Section 2.3(c) in respect of any unreimbursed portion of any L/C Disbursement is made after the date such payment is due, such Participating Bank shall additionally pay to the Administrative Agent, for the account of the Issuing Bank, on demand, an amount equal to the product of (i) such amount, times (ii) the Applicable Rate, as defined below, times (iii) a fraction the numerator of which is the number of days during the period commencing on such due date and ending on the date on which payment is made (the "DELINQUENCY PERIOD") and the denominator of which is 360. As used in this subsection, "Applicable Rate" means (x) if the Delinquency Period is 3 days or less, the daily average Federal Funds Rate during the Delinquency Period, and (y) in all other cases, the daily average Base Rate during the Delinquency Period.

certificate of the Administrative Agent submitted to any Participating Bank with respect to any amounts owing under this subsection shall be conclusive in the absence of manifest error. For purposes of this subsection, payment by any Participating Bank to the Administrative Agent shall not be deemed made until such time as that payment is available to the Administrative Agent in immediately available funds. (e) Whenever, at any time after the Issuing Bank has made an L/C Disbursement and has received from any Participating Bank (through the Administrative Agent) that Participating Bank's PRO RATA share of such L/C Disbursement in accordance with section 2.3(c), the Administrative Agent receives any payment on account of such L/C Disbursement (whether or not such L/C Disbursement has been treated as a Drawing Loan under subsection (c), and whether such payment is received directly from the Company or otherwise, including proceeds of collateral applied thereto by the Issuing Bank), or any payment of interest on account thereof, the Administrative Agent will distribute to such Participating Bank that Participating Bank's L/C Commitment Percentage of such payment. SECTION 2.4 AGREEMENT OF THE COMPANY AND EACH PARTICIPATING BANK. Without limiting the effect of subsection 2.3, the Company and each Participating Bank agree with the Issuing Bank that: (a) The Issuing Bank is authorized to make payments under the Letter of Credit upon the presentation of the documents provided for therein and without regard to whether the Company has failed to fulfill any of its obligations with respect to any Related Document or any other default has occurred thereunder. (b) The Issuing Bank is authorized to take such action on its behalf under the provisions of this Agreement and to exercise such powers and perform such duties as are specifically delegated to or required of the Issuing Bank by the terms hereof, together with such powers as are reasonably incidental thereto. (c) The Issuing Bank shall be entitled to rely upon any certificate, notice, demand or other communication (whether by cable, telegram, telecopy, S.W.I.F.T., telex or other written communication) believed by it to be genuine and to have been signed or sent by the proper Person or Persons (and no such reliance or failure shall place the Issuing Bank under any liability to the Company or any Participating Bank or limit or otherwise affect the Company's or any Participating Bank's obligations under this Agreement). (d) Any action, inaction or omission on the part of the Issuing Bank under or in connection with the Letter of Credit or the instruments or documents related thereto, if in good faith and in conformity with such laws, regulations or customs as the Issuing Bank may reasonably deem to be applicable, shall be binding upon the Company and each Participating Bank (and shall not place the Issuing Bank under any liability to the Company or any Participating Bank or limit or otherwise affect the Company's or any Participating Bank's obligations under this Agreement). -11-

(e) Notwithstanding any change or modification, with or without the consent of the Company, in any instruments or documents called for in the Letter of Credit, including waiver of noncompliance of any such instruments or documents with the terms of the Letter of Credit, this Agreement shall be binding on the Company with regard to the Letter of Credit and to any action taken by the Issuing Bank relative thereto. (f) The Company shall indemnify and hold harmless each Bank from any loss or expense arising from or in connection with the Letter of Credit (except to the extent that such loss or expense arises directly from the gross negligence or willful misconduct of the Issuing Bank). SECTION 2.5 INTEREST RATES AND PAYMENT DATES. Each Drawing Loan shall bear interest determined as follows (the "UNREIMBURSED DRAWING RATE"): (a) through the third Business Day following the corresponding L/C Disbursement, at the Base Rate; (b) thereafter for the immediately following 6 Interest Periods, at a rate per annum equal to the LIBOR applicable to such Interest Periods, plus the Applicable Margin; (c) thereafter through the day preceding the first anniversary of such L/C Disbursement Date, at a rate per annum equal to the Base Rate; and (d) thereafter, at a rate per annum equal to the Base Rate plus 2%. Interest on all Drawing Loans shall be payable on demand or, if demand is not sooner made, on the last day of each calendar quarter. SECTION 2.6 PAYMENTS. (a) To the extent the Administrative Agent actually receives payment in respect of principal of or interest on any Pledged Bond, the Drawing Loan made in connection with the purchase of such Pledged Bond shall be deemed to have been reduced PRO TANTO, with the Issuing Bank crediting any interest payment on the Pledged Bond received by it to the payment of interest on the related Drawing Loan (and, after payment of all interest accrued on the related Drawing Loan, to the payment of principal of the related Drawing Loan) and crediting any principal repayment received to the principal thereof (and, after payment of all principal of the related Drawing Loan, to the payment of interest accrued on the related Drawing Loan); PROVIDED that if such interests or principal payments on such Pledged Bonds are derived from the Letter of Credit, any such payments shall not be credited against the Drawing Loans unless the Company has fully reimbursed the Issuing Bank for such amounts derived from the Letter of Credit. Prior to the occurrence of an Event of Default the Issuing Bank agrees that any amount actually received by it in respect of principal of or interest on such Pledged Bonds and not credited to the payment of principal of or interest on the related Drawing Loan as -12-

provided in the preceding sentence shall be paid promptly to the Company unless such funds have been derived from a draw on the Letter of Credit which has not been fully reimbursed by the Company in which case only such amounts in excess of the amount necessary to fully reimburse the Issuing Bank for such payment from the Letter of Credit shall be returned to the Company. After the occurrence and during the continuance of an Event of Default any such excess shall be held as collateral for the Obligations pursuant to the terms of Section 6.2(a) and 6.3. Any such payment of a Drawing Loan will be subject, in the case of the first 180 days, to Section 2.16(a) hereof. (b) Each payment (including each prepayment) by the Company on account of principal of and interest on the Obligations payable to the Participating Banks hereunder shall be made PRO RATA according to the respective outstanding principal amounts of the Obligations then held by the Participating Banks. The Administrative Agent shall distribute such payments to the Participating Banks promptly upon receipt in like funds as received. (c) The Administrative Agent agrees that upon any payment of principal by the Company on a Drawing Loan (other than a payment deemed made pursuant to Section 2.6(a) above) the Administrative Agent will promptly thereafter direct the Trustee to transfer to the Company a corresponding amount of Pledged Bonds PROVIDED that the Administrative Agent shall only be obligated to transfer Pledged Bonds in an amount equal to Authorized Denominations. (d) Unless the Administrative Agent shall have received notice from the Company no later than 12:00 noon on the date on which any payment is due to the Participating Banks hereunder that the Company will not make such payment in full, the Administrative Agent may assume that the Company will make such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Participating Bank on such due date an amount equal to the amount then due such Participating Bank. If and to the extent the Company shall not have so made such payment in full to the Administrative Agent, each Participating Bank shall repay to the Administrative Agent forthwith on demand such amount distributed to such Participating Bank, together with interest thereon at the Federal Funds Rate for each day from the date such amount is distributed to such Participating Bank until the date such Participating Bank repays such amount to the Administrative Agent. A certificate of the Administrative Agent submitted to any Participating Bank with respect to any amounts owing by such Participating Bank under this paragraph (d) shall be conclusive and binding for all purposes absent manifest error. SECTION 2.7 SECURITY INTEREST IN PLEDGED BONDS. The Company hereby grants to the Administrative Agent, for the benefit of each of the Banks, a first priority security interest in all of its right, title and interest in and to all Pledged Bonds to secure the repayment of the Obligations.

The Company hereby agrees from time to time, at the request of the Administrative Agent, to cause any financing statements to be filed, registered and recorded in such manner and in all places as may be required by law or reasonably -13-

requested by the Administrative Agent in order to fully perfect and protect any lien and security interest created hereby and from time to time will perform or cause to be performed any other act as provided by law and will execute or cause to be executed any and all continuation statements and further instruments that may be reasonably requested or required by the Administrative Agent for such perfection and protection. The Administrative Agent hereby appoints the Trustee as its bailee for purposes of perfecting its security interest in the Pledged Bonds. SECTION 2.8 FEES. The Company will pay, or cause to be paid, to the Administrative Agent: (a) for the account of the Participating Banks in accordance with their respective Commitment Percentages, a letter of credit fee on the average daily Available Amount at a rate equal to the L/C Margin. Such fee shall be payable in arrears on the last day of each calendar quarter and on the Termination Date, unless the Letter of Credit is terminated in whole on any earlier date, in which event the letter of credit fee for the period to the date of such termination shall be paid on the date of such termination; (b) for the account of the Issuing Bank, on demand, all administrative fees charged by the Issuing Bank in the ordinary course of business in connection with the honoring of drafts under the Letter of Credit, amendments thereto, transfers thereof and all other activity with respect to the Letter of Credit at the then current rates published by the Bank for such services rendered on behalf of customers of the Issuing Bank generally; and (c) for the account of the Administrative Agent, on the date of each transfer of the Letter of Credit to a successor Trustee, a transfer fee in an amount equal to the Issuing Bank's then standard out-of-pocket fee for transfers in effect on such date. SECTION 2.9 METHOD OF PAYMENT. All payments to be made by the Company and the Participating Banks under this Agreement shall be made to the Administrative Agent at Wells Fargo Bank, National Association, ABA No. 121000248, reference: ALLETE, Inc., not later than 3:00 p.m., on the date when due and shall be made in lawful money of the United States of America (in freely transferable U.S. dollars) and in immediately available funds. SECTION 2.10 LENDING OFFICES AND FUNDING. Each Participating Bank may fund its Drawing Loans at such branch, office or affiliate as it may from time to time elect and designate in a written notice to the Administrative Agent and the Company. Notwithstanding any other provision of this Agreement, each Participating Bank shall be entitled to fund and maintain its funding of all or any part of each Drawing Loan in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if in the first 180 days the Issuing Bank had actually funded and maintained such Drawing Loan through the purchase of deposits in the eurodollar interbank market having a maturity corresponding to the Interest Periods applicable to such -14-

Drawing Loan and bearing an interest rate equal to the applicable LIBOR for such Interest Periods. SECTION 2.11 COMPUTATION OF INTEREST. All computations of interest and fees payable by the Company under this Agreement shall be made on the basis of a 360-day year and actual days elapsed except where interest is computed using the Base Rate, in which case a year of 365 or 366 days and actual days elapsed shall be used. Interest shall accrue during each period during which interest is computed from and including the first day thereof to but excluding the last day thereof. SECTION 2.12 PAYMENT DUE ON NON-BUSINESS DAY TO BE MADE ON NEXT BUSINESS DAY. If any sum becomes payable pursuant to this Agreement on a day which is not a Business Day, the date for payment thereof shall be extended, without penalty, to the next succeeding Business Day, and such extended time shall be included in the computation of interest and fees. If the date for any payment of principal is extended by operation of law or otherwise, interest shall be payable for such extended time. SECTION 2.13 LATE PAYMENTS. Except as set forth in Section 2.5, if the principal amount of any Obligation is not paid when due, such Obligation shall bear interest from the due date thereof until paid in full at a rate per annum equal to the Base Rate from time to time in effect plus 2%, payable on demand.

(a) No later than 90 days before each anniversary date of this Agreement the Company may make a request for a one-year extension of the Stated Expiration Date in a written notice to the Administrative Agent. The Administrative Agent will promptly inform the Issuing Bank and the Participating Banks of any such request. Each of the Issuing Bank and each Participating Bank may, in its sole and absolute discretion, determine whether to consent to such request. If each of the Issuing Bank and each Participating Bank shall give irrevocable written notice to the Administrative Agent not later than 45 days prior to such Stated Expiration Date stating that it is so willing to extend the Stated Expiration Date, then, subject to any conditions precedent that the Administrative Agent may require in connection with such extension (e.g., the remaking of representations and warranties, no Potential Default or Event of Default having occurred or the delivery of a legal opinion and other appropriate documentation), the Stated Expiration Date shall be so extended, such extension to be effective as provided in Section 2.15(b) and the Administrative Agent shall promptly notify the Issuing Bank, the Participating Banks and the Company of such circumstance. Failure by the Issuing Bank or any Participating Bank to deliver such a notice to the Administrative Agent within -15-

such time frame shall be deemed to be a denial of the Company's request by the Issuing Bank or such Participating Bank. If the Issuing Bank and each Participating Bank have not delivered written notices in accordance with the terms hereof consenting to the extension of the Stated Expiration Date, the Stated Expiration Date shall not be extended and the Administrative Agent shall promptly notify the Issuing Bank, the Participating Banks and the Company of such circumstance. Any date to which the Stated Expiration Date has been extended in accordance with this Section 2.15 may be extended in like manner. (b) If the Stated Expiration Date is extended pursuant to Section 2.15(a), the Issuing Bank shall deliver to the Trustee an amendment (an "Extension Amendment") designating the date to which the Stated Expiration Date is being extended. Such extension of the Stated Expiration Date shall be effective, after receipt of such notice, on the Business Day following the date of delivery of such Extension Amendment, and thereafter all references in this Agreement to the Stated Expiration Date shall be deemed to be references to the date designated as such in the most recent Extension Amendment delivered to the Trustee.

(b) BASIS FOR DETERMINING INTEREST RATE UNAVAILABLE. If on or prior to the first day of any Interest Period deposits in dollars (in the applicable amounts) are not being offered to a Participating Bank in the London interbank market for such Interest Period, such Participating Bank shall forthwith give notice thereof to the Administrative Agent and the Company, whereupon the obligation of the Banks to make a Drawing Loan at LIBOR shall be suspended until that Participating Bank notifies the Company that the circumstances giving rise to such suspension no longer exist. Such Participating Bank shall instead make such Drawing Loan at the Base Rate for the first 365 days. (c) ILLEGALITY. If after the Date of Issuance the adoption of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Participating Bank with any request or directive (whether or not having the force of law) -16-

of any such authority, central bank or comparable agency shall make it unlawful or impossible for any Participating Bank to make, maintain or fund its Drawing Loans at LIBOR, such Participating Bank shall forthwith so notify the Administrative Agent and the Company, whereupon such Participating Bank's obligation to fund any Drawing Loans at LIBOR shall be suspended. If any Participating Bank shall determine that it may not lawfully continue to maintain and fund any of its outstanding Drawing Loans bearing interest at LIBOR to maturity and shall so specify in such notice, the Company shall immediately prepay in full the then outstanding principal amount of each such Drawing Loan bearing interest at LIBOR, together with accrued interest thereon. Concurrently with prepaying each such Drawing Loan, the Company may borrow a Drawing Loan at the Base Rate in an equal principal amount for a period coincident with the remaining term of the Interest Period applicable to such Drawing Loan. SECTION 2.17 RESCISSION OF PAYMENTS. If, following the payment of any Reimbursement Obligation or any interest thereon by the Company to the Administrative Agent pursuant to Section 2.6, any portion of such Reimbursement Obligation and/or interest shall he rescinded or must otherwise be restored by the Issuing Bank, then each Participating Bank, upon notice to it by the Administrative Agent of such rescission or restoration, shall pay to the Administrative Agent its Commitment Percentage of the amount so rescinded or restored.

(h) The consolidated financial statements of the Company and its consolidated subsidiaries as of December 31, 2004 and December 31, 2005 contained in the Company's Annual Report on Form 10-K for the years ended on those dates, copies of which have been furnished to the Banks, present fairly the consolidated financial position of the Company and its Consolidated Subsidiaries as of those dates and the results of their operations for the two years ended December 31, 2005, in conformity with generally accepted accounting principles consistently applied. The consolidated financial statements contained in the Company's Quarterly Reports on Form 10-Q for the quarter ended March 31, 2006, copies of which have been furnished to the Bank, present fairly the consolidated financial position of the Company and its Consolidated Subsidiaries as of the dates thereof and have been prepared in conformity with generally accepted accounting principles applied on the basis consistent with that used in the audited consolidated financial statements for the year ended December 31, 2005 (subject to normal year-end and audit adjustments).

On the basis of this review, the Company has no reason to conclude that such liabilities and costs arising under, including the costs of compliance with, Environmental Laws, could reasonably constitute, cause or result in a Material Adverse Change.

"OTHER TAXES" means any present or future stamp or documentary taxes and any other excise or property taxes, or similar charges or levies and all penalties and interest with respect thereto, which arise from the making of any payment pursuant to this Agreement or from the execution or delivery of this Agreement or the Letter of Credit. (b) Any and all payments by the Company to or for the account of any Bank hereunder shall be made without deduction for any Taxes or Other Taxes; PROVIDED that, if the Company shall be required by law to deduct any Taxes or Other Taxes from any such payments, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the applicable Bank receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Company shall make such deductions, (iii) the Company shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law and (iv) the Company shall furnish to the Banks, the original or a certified copy of a receipt evidencing payment thereof.

This indemnification shall be paid within 15 days after any Bank makes appropriate demand therefor.

(e) For any period with respect to which any Bank has failed to provide the Company with the appropriate form pursuant to Section 7.1(d) (unless such failure is due to a change in treaty, law or regulation occurring subsequent to the date on which such form originally was required to be provided), such Bank shall not be entitled to indemnification under Section 7.1(b) or (c) with respect to Taxes imposed by the United States; PROVIDED that, if such Bank, which is otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to Taxes because of its failure to deliver a form required hereunder, the Company shall take such steps (at the expense of such Bank) as such Bank shall reasonably request to assist such Bank to recover such Taxes. (f) If the Company is required to pay additional amounts to or for the account of any Bank pursuant to this Section, then such Bank will change the jurisdiction of its applicable lending office if, in the judgment of such Bank, such change (i) will eliminate or reduce any such additional payment which may thereafter accrue and (ii) is not otherwise disadvantageous to such Bank in its sole judgment.

The protection of this paragraph shall be available to each Bank regardless of any possible contention of invalidity or inapplicability of the law, regulation or condition which has been imposed; PROVIDED, HOWEVER, that if it shall later be determined by such -32-

Bank that any amount so paid by the Company pursuant to this Section 7.2 is in excess of the amount payable under the provisions hereof, such Bank shall refund such excess amount to the Company. (b) Without limiting the effect of the foregoing, the Company shall pay to the Issuing Bank and each Participating Bank on the last day of each Interest Period so long as such Bank is maintaining reserves against "EUROCURRENCY LIABILITIES" under Regulation D (or so long as such Bank is, by reason of any Regulatory Change, maintaining reserves against any other category of liabilities that includes deposits by reference to which the interest rate on Drawing Loans bearing interest at LIBOR is determined as provided in this Agreement or against any category of extensions of credit or other assets of such Bank that includes any Drawing Loans bearing interest at LIBOR) an additional amount (determined by such Bank and notified to the Company) equal to the product of the following for each such Drawing Loan for each day during such Interest Period: (i) the principal amount of such Drawing Loan outstanding on such day; (ii) the remainder of (x) a fraction the numerator of which is the rate (expressed as a decimal) at which interest accrues on such Drawing Loan for such Interest Period as provided in this Agreement and the denominator of which is one minus the effective rate (expressed as a decimal) at which such reserve requirements are imposed on such Bank on such day minus (y) such numerator; and (iii) 1/360.

(c) The rights of any Bank under this Section 7.3 are in addition to, in augmentation of, and, except as specifically provided in this Section 7.3, do not derogate from or impair other rights and remedies (including, without limitation, other rights of setoff) which such Bank may have.

(b) The Company shall pay (i) all reasonable costs and out-of-pocket expenses of the Issuing Bank and the Administrative Agent, including, without limitation, costs in connection with the negotiation, documentation and execution of this Agreement and any and all documents, agreements and instruments related thereto, reasonable fees and disbursements of special counsel for the Issuing Bank and the Administrative Agent, in -34-

Nothing in this subsection is intended to limit the payment and reimbursement obligations of the Company contained in this Agreement. -35-

(e) The foregoing agreements and indemnities shall remain operative and in full force and effect regardless of termination of this Agreement, the consummation of or failure to consummate either the transactions contemplated by this Agreement or any amendment, supplement, modification or waiver, the drawing of any draft and reimbursement of the Issuing Bank therefor, the invalidity or unenforceability of any term or provision of this Agreement, any Related Documents, or any other document required hereunder or thereunder, any investigation made by or on behalf of the Administrative Agent, or the Company or the content or accuracy of any representation or warranty made under this Agreement, any Related Documents or any other document required hereunder or thereunder.

Neither the Issuing Bank nor any of its officers or directors shall be liable or responsible for (a) the use of the Letter of Credit or for any acts or omissions of the Trustee and any transferee in connection therewith, (b) the validity or genuineness of documents, or of any endorsement thereon, even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged, (c) payment by the Issuing Bank against presentation of documents which do not comply with the terms of the Letter of Credit, including failure of any documents to bear any reference or adequate reference to the Letter of Credit, or (d) any other circumstances whatsoever in making or failing to make payment under the Letter of Credit; PROVIDED, HOWEVER, that the Company shall have a claim against the Issuing Bank, and the Issuing Bank shall be liable to the Company, to the extent of any direct, as opposed to consequential, damages suffered by the Company which the Company proves were caused by (i) the Issuing Bank's willful misconduct or gross negligence in determining whether documents presented under the Letter of Credit comply with the terms of the Letter of Credit or (ii) the Issuing Bank's wrongful failure to make lawful payment under the Letter of Credit after the presentation to the Issuing Bank by the Trustee or a successor trustee under the Indenture of a draft and certificate strictly complying with the terms and conditions of the Letter of Credit (it being understood that in making such payment the Issuing Bank's exclusive reliance on the documents presented to the Issuing Bank in accordance with the terms of the Letter of Credit as to any and all matters set forth therein, whether or not any statement or any document presented pursuant to the Letter of Credit proves to forged, fraudulent, invalid or insufficient in any respect or any statement whatsoever, shall not be deemed willful misconduct or gross negligence of the Issuing Bank). The Issuing Bank is hereby expressly authorized and directed to honor any demand for payment which is made under the Letter of Credit without regard to, and without any duty on its part to inquire into the existence of, any disputes or controversies between the Issuer, the Company, the Remarketing Agent, the Trustee, any Paying Agent, or any other person or the respective rights, duties or liabilities of any of them, or whether any facts or occurrences represented in any of the documents presented under the Letter of Credit are true and correct. SECTION 7.8 PARTICIPANTS, ETC. (a) Each Participating Bank shall have the right at any time, with the written consent of the Company (which consent shall not be unreasonably withheld) and the Issuing Bank (which consent shall be granted in the sole discretion of the Issuing Bank), to assign all or any part of its L/C Commitment (including the corresponding portion of its Commitment Percentage) to one or more other Persons; PROVIDED that such assignment is in an amount of at least $5,000,000 or the entire L/C Commitment of such Participating Bank, and if such assignment is not for such Participating Bank's entire L/C Commitment then such Participating Bank's L/C Commitment after giving effect to such assignment shall not be less than $5,000,000. Each such assignment shall set forth the assignees address for notices to be given hereunder. Upon any such assignment, delivery to the Administrative Agent of an executed copy of such assignment agreement and the forms referred to in Section 7.1 hereof, if applicable, and the payment of a $3,500 recordation -37-

fee to the Administrative Agent, the assignee shall become a Participating Bank hereunder, and the Participating Bank granting such assignment shall have its L/C Commitment (including the corresponding portion of its Commitment Percentage), and its obligations and rights in connection therewith, reduced by the amount of such assignment. (b) Each Participating Bank shall have the right at its own cost to grant participations (to be evidenced by one or more agreements or certificates of participation) in the L/C Commitments, and its corresponding participation obligation in the Letter of Credit, held by such Participating Bank at any time; PROVIDED that (i) no such participation shall relieve any Participating Bank of any of its obligations under this Agreement, (ii) no such participant shall have any rights under this Agreement except as provided in this Section 7.8(b), and (iii) neither the Issuing Bank nor the Administrative Agent shall have any obligation or responsibility to such participant. Any party to which such a participation has been granted shall have the benefits of Sections 7.1, 7.2, 7.3, 7.4 and 7.15, but shall not be entitled to receive any greater payment under such Sections than the Participating Bank granting such participation would have been entitled to receive in connection with the rights transferred. Any agreement pursuant to which any Participating Bank may grant such a participating interest shall provide that such Participating Bank shall retain the sole right and responsibility to enforce the obligations of the Company hereunder, including, without limitation, the right to approve any amendment, modification or waiver of any provision of this Agreement; PROVIDED that such participation agreement may provide that such Participating Bank will not agree to any modification, amendment or waiver of this Agreement that would (A) increase or extend any L/C Commitment of such Participating Bank if such increase or extension would also increase or extend the participant's obligations, (B) forgive any amount of or postpone the date for payment of any principal of or interest on any Obligation payable hereunder in which such participant has an interest or (C) reduce the stated rate at which interest or fees in which such participant has an interest accrue hereunder. SECTION 7.9 SURVIVAL OF THIS AGREEMENT. All covenants, agreements, representations and warranties made in this Agreement shall survive the issuance by the Issuing Bank of the Letter of Credit and shall continue in full force and effect so long as the Letter of Credit shall be unexpired or any sums drawn or due hereunder shall be outstanding and unpaid, regardless of any investigation made by any person. Wherever in this Agreement the Issuing Bank is referred to, such reference shall be deemed to include the successors and assigns of the Issuing Bank and all covenants, promises and agreements by or on behalf of the Company which are contained in this Agreement shall inure to the benefit of the successors and assigns of the Issuing Bank. The rights and duties of the Company, however, may not he assigned or transferred, except as specifically provided in this Agreement or with the prior written consent of the Administrative Agent, and all obligations of the Company hereunder shall continue in full force and effect notwithstanding any assignment by the Company of any of its rights or obligations under any of the Bond Documents or any entering into, or consent by the Company, to any supplement or amendment to any of the Bond Documents. -38-

ARTICLE VIII THE ADMINISTRATIVE AGENT SECTION 8.1 APPOINTMENT AND AUTHORIZATION OF ADMINISTRATIVE AGENT. Each Participating Bank hereby appoints Wells Fargo Bank, National Association, as the Administrative Agent under this Agreement and hereby authorizes the Administrative Agent to take such action as Administrative Agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto. The relationship between the Administrative Agent and the Participating Bank is and shall be that of agent and principal only, and nothing contained in this Agreement or the Letter of Credit shall be construed to constitute the Administrative Agent as a trustee or fiduciary for any Participating Bank or the Company. SECTION 8.2 ADMINISTRATIVE AGENT AND ITS AFFILIATES. The Administrative Agent shall have the same rights and powers under this Agreement as any other Participating Bank and may exercise or refrain from exercising the same as though it were not the Administrative Agent, and the Administrative Agent and its affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Company or any affiliate of the Company as if it were not the Administrative Agent hereunder. The term "PARTICIPATING BANK" as used herein, unless the context otherwise clearly requires, includes the Administrative Agent in its individual capacity as a Participating Bank. SECTION 8.3 ACTION BY ADMINISTRATIVE AGENT. If the Administrative Agent delivers to the Company a written notice of an Event of Default hereunder, the Administrative Agent shall promptly give each of the Participating Banks written notice thereof. The obligations of the Administrative Agent hereunder are only those expressly set forth herein. Without limiting the generality of the foregoing, the Administrative Agent shall not be required to take any action hereunder with respect to any Potential Default or Event of Default. In no event, however, shall the Administrative Agent be required to take any action in violation of applicable law or of this Agreement, and the Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder or under the Letter of Credit unless it shall be first indemnified to its reasonable satisfaction by the Participating Banks against any and all costs, expense, and liability which may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall be entitled to assume that no Potential Default or Event of Default exists unless notified to the contrary by a Participating Bank or the Company. In all cases in which this Agreement and the Letter of Credit do not require the Administrative Agent to take certain actions, the Administrative Agent shall be fully justified in using its discretion in failing to take or in taking any action hereunder and thereunder. SECTION 8.4 CONSULTATION WITH EXPERTS. The Administrative Agent may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts. -43-

SECTION 8.5 LIABILITY OF ADMINISTRATIVE AGENT; CREDIT DECISION. Neither the Administrative Agent nor any of its directors, officers, agents, or employees shall be liable for any action taken or not taken by it in connection transactions contemplated by this Agreement (i) with the consent or at the request of the Majority Participating Banks or (ii) in the absence of its own gross negligence or willful misconduct. Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into or verify (i) any statement, warranty or representation made in connection with this Agreement or the Letter of Credit; (ii) the performance or observance of any of the covenants or agreements of the Company or any other party contained herein or in the Letter of Credit; (iii) the satisfaction of any condition specified in Section 3.1 or 3.2 hereof, except receipt of items required to be delivered to the Administrative Agent; or (iv) the validity, effectiveness, genuineness, enforceability, perfection, value, worth or collectibility hereof or of any other documents or writing furnished in connection herewith; and the Administrative Agent makes no representation of any kind or character with respect to any such matter mentioned in this sentence. The Administrative Agent may execute any of its duties under this Agreement or the Letter of Credit by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Participating Banks, the Company, or any other Person for the default or misconduct of any such agents or attorneys-in-fact selected with reasonable care. The Administrative Agent shall not incur any liability by acting in reliance upon any notice, consent, certificate, other document or statement (whether written or oral) believed by it to he genuine or to be sent by the proper party or parties. Each Participating Bank acknowledges that it has independently and without reliance on the Administrative Agent or any other Participating Bank, and based upon such information, investigations and inquiries as it deems appropriate, made its own credit analysis and decision to extend credit to the Company in the manner set forth herein. It shall be the responsibility of each Participating Bank to keep itself informed as to the creditworthiness of the Company and any other relevant Person, and the Administrative Agent shall have no liability to any Participating Bank with respect thereto. SECTION 8.6 INDEMNITY. The Participating Banks shall ratably, in accordance with their respective Commitment Percentage, indemnify and hold the Administrative Agent, and its directors, officers, employees, agents and representatives harmless from and against any liabilities, losses, costs or expenses suffered or incurred by it hereunder or in connection with the transactions contemplated hereby, regardless of when asserted or arising, except to the extent they are promptly reimbursed for the same by the Company and except to the extent that any event giving rise to a claim was caused by the gross negligence or willful misconduct of the party seeking to be indemnified. The obligations of the Participating Banks under this Section 8.6 shall survive termination of this Agreement. SECTION 8.7 RESIGNATION OF ADMINISTRATIVE AGENT AND SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent may resign at any time by giving written notice thereof to the Participating Banks and the Company. Upon any such resignation of the Administrative Agent, the Majority Participating Banks shall have the right to appoint a successor Administrative Agent with the consent of the Company. If no successor Administrative Agent shall have been so -44-

appointed by the Majority Participating Banks, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent's giving of notice of resignation, then the retiring Administrative Agent may, on behalf of the Participating Banks, appoint a successor Administrative Agent, which shall be any Participating Bank hereunder or any commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $200,000,000. Upon the acceptance of its appointment as the Administrative Agent hereunder, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring or removed Administrative Agent hereunder, and the retiring Administrative Agent shall be discharged from its duties and obligations thereunder. After any retiring Administrative Agent's resignation hereunder as Administrative Agent, the provisions of this Section 8.7 and all protective provisions hereof shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent.

EXHIBIT 99 [ALLETE LOGO] For Release: July 28, 2006 CONTACT: Eric Olson 218-723-3947 eolson@allete.com INVESTOR Tim Thorp CONTACT: 218-723-3953 tthorp@allete.com NEWS ALLETE REPORTS SECOND QUARTER 2006 EARNINGS ------------------------------------------- EARNINGS PER SHARE FROM CONTINUING OPERATIONS INCREASE 29%, EXCLUDING ONE-TIME 2005 CHARGE ALLETE (NYSE: ALE) today reported second quarter 2006 earnings from continuing operations of $0.49 per diluted share compared to a loss of $1.46 in the second quarter of 2005. The results a year ago were impacted by a $1.84 per share charge related to the assignment of a Kendall County, Ill. power purchase agreement. Excluding that one-time charge, ALLETE's second quarter earnings per share from continuing operations are 29 percent higher in 2006 than in 2005. "Halfway though the year, ALLETE's earnings are where we expected them to be," said CEO Don Shippar. "We anticipate our 2006 earnings per share from continuing operations, as we projected earlier, will increase 15 percent to 20 percent over 2005." During the quarter, income from ALLETE's real estate segment was driven by contract closings at the Town Center at Palm Coast development in northeast Florida. ALLETE Properties net income doubled from $2.8 million in 2005 to $5.6 million in 2006. As of June 30, 2006, ALLETE had a total of $128.9 million of land sales under contract, up from $85.3 million at the end of March 2006. Those contracts are expected to close over the next several years. Earnings from ALLETE's energy businesses were $7.7 million in the second quarter of 2006, the same as the comparable period a year ago, excluding the one-time Kendall charge. Plant maintenance at Minnesota Power generating facilities resulted in $1.1 million of additional after-tax operating and maintenance expense during the quarter compared to 2005. In late May, ALLETE made its initial investment in the American Transmission Company and as of June 30, had invested a total of $11.5 million. Shippar said the income contribution from ATC will accelerate as ALLETE continues to make additional investments during the year. He noted that the company intends to invest an additional $48.5 million in ATC by year-end, giving ALLETE an ownership interest of approximately nine percent. ALLETE's corporate headquarters are located in Duluth, Minnesota. ALLETE provides energy services in the upper Midwest and has significant real estate holdings in Florida. More information about the company is available on ALLETE's Web site at www.allete.com. -------------- THE STATEMENTS CONTAINED IN THIS RELEASE AND STATEMENTS THAT ALLETE MAY MAKE ORALLY IN CONNECTION WITH THIS RELEASE THAT ARE NOT HISTORICAL FACTS, ARE FORWARD-LOOKING STATEMENTS.
