Item 1. Business

Overview.

Part I

ALLETE is a leader in the nation’s clean-energy transformation. Our businesses and dedicated employees deliver sustainable energy solutions that mitigate
climate change, build thriving communities, help customers reach their sustainability goals and drive value for shareholders. ALLETE’s largest business,
Minnesota  Power,  recently  reached  a  milestone  of  providing  50  percent  renewable  energy,  and  envisions  delivering  100  percent  carbon-free  energy  to
customers by 2050—a vision grounded in a steadfast commitment to climate, customers and community through its EnergyForward  strategy.  ALLETE
Clean Energy, our second-largest business, is positioned at the heart of society’s clean-energy transformation and owns, operates and is developing more
than 1,300 megawatts of wind energy generation across eight states – helping some of the largest companies in the country reduce their carbon footprint.

In February 2021, Minnesota Power filed its latest IRP with the MPUC, which outlines its clean-energy transition plans through 2035. These plans include
expanding  its  renewable  energy  supply  to  70  percent  by  2030,  achieving  coal-free  operations  at  its  facilities  by  2035,  and  investing  in  a  resilient  and
flexible transmission and distribution grid. Minnesota Power has also set a target to achieve an 80 percent reduction in carbon emissions by 2035 compared
to  2005  levels.  As  part  of  these  plans,  Minnesota  Power  anticipates  adding  approximately  400  MW  of  new  wind  and  solar  energy  resources,  retiring
Boswell Unit 3 by 2030 and transforming Boswell Unit 4 to be coal-free by 2035. Minnesota Power’s plans recognize that advances in technology will play
a significant role in completing its transition to carbon-free energy supply, reliably and affordably. A final decision on the IRP is expected in second half of
2022.

In recent years, Minnesota Power has transformed its energy supply from more than a 95 percent reliance on coal to become a leader in the nation’s clean-
energy transformation. Since 2013, the company has closed or converted seven of its nine coal-fired units and added nearly 900 megawatts of renewable
energy sources. Additionally, Minnesota Power has been a leader in energy conservation, surpassing the state’s conservation goals each year for the past
decade.

ALLETE  is  also  committed  to  earning  a  financial  return  that  rewards  our  shareholders,  allows  for  reinvestment  in  our  businesses,  and  sustains  growth.
ALLETE  is  predominately  a  regulated  utility  through  Minnesota  Power,  SWL&P,  and  an  investment  in  ATC.  ALLETE’s  strategy  is  to  remain
predominately  a  regulated  utility  while  also  investing  in  ALLETE  Clean  Energy  and  our  Corporate  and  Other  businesses  to  complement  its  regulated
businesses, balance exposure to the utility’s industrial customers, and provide potential long-term earnings growth.

The ongoing COVID-19 pandemic has resulted in widespread impacts on the global economy and on our employees, customers, contractors, and suppliers.
There is considerable uncertainty regarding the length of time for which COVID-19 will continue, if new variants will emerge or the extent and duration of
measures to try to contain the virus. Additional disclosures in this Form 10-K regarding the impacts of the ongoing COVID-19 pandemic are located in
Item 1A. Risk Factors and Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Regulated Operations  includes  our  regulated  utilities,  Minnesota  Power  and  SWL&P,  as  well  as  our  investment  in  ATC,  a  Wisconsin-based  regulated
utility  that  owns  and  maintains  electric  transmission  assets  in  portions  of  Wisconsin,  Michigan,  Minnesota  and  Illinois.  Minnesota  Power  provides
regulated  utility  electric  service  in  northeastern  Minnesota  to  approximately  150,000  retail  customers.  Minnesota  Power  also  has  15  non-affiliated
municipal  customers  in  Minnesota.  SWL&P  is  a  Wisconsin  utility  and  a  wholesale  customer  of  Minnesota  Power.  SWL&P  provides  regulated  utility
electric,  natural  gas  and  water  service  in  northwestern  Wisconsin  to  approximately  15,000  electric  customers,  13,000  natural  gas  customers  and
10,000  water  customers.  Our  regulated  utility  operations  include  retail  and  wholesale  activities  under  the  jurisdiction  of  state  and  federal  regulatory
authorities. (See Note 4. Regulatory Matters.)

ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects. ALLETE Clean Energy currently owns and
operates,  in  seven  states,  more  than  1,300  MW  of  nameplate  capacity  wind  energy  generation  that  is  contracted  under  PSAs  of  various  durations.  In
addition, ALLETE Clean Energy currently has approximately 200 MW of wind energy facilities under contract to be sold to others. ALLETE Clean Energy
also engages in the development of wind energy facilities to operate under long-term PSAs or for sale to others upon completion.

Industrial Customers. In 2021, industrial customers represented 47 percent of total regulated utility kWh sales. Our industrial customers are primarily in
the taconite mining, paper, pulp and secondary wood products, and pipeline industries.

The  ongoing  COVID-19  pandemic  and  related  governmental  responses  has  led  to  a  disruption  of  economic  activity,  and  could  result  in  an  extended
disruption  of  economic  activity.  This  disruption  resulted  in  reduced  sales  and  revenue  from  industrial  customers  in  2020  as  many  industrial  customers
operated at reduced levels or were temporarily closed or idled during 2020. Sales to our industrial customers in 2021 were similar to levels prior to the
COVID-19  pandemic;  however,  further  disruption  of  economic  activity  or  an  extended  disruption  of  economic  activity  may  lead  to  additional  adverse
impacts on our industrial customers including reduced production or the temporary idling or indefinite shutdown of facilities, which would result in lower
sales and revenue from these customers.

Six taconite facilities served by Minnesota Power made up approximately 80 percent of 2020 iron ore pellet production in the U.S. according to data from
the Minnesota Department of Revenue 2021 Mining Tax Guide. These taconite facilities were owned by Cliffs and USS Corporation at the end of the 2021.
(See Large Power Customer Contracts.) Sales to taconite customers represented 5,281 million kWh, or 73 percent of total industrial customer kWh sales in
2021. Taconite, an iron‑bearing rock of relatively low iron content, is abundantly available in northern Minnesota and an important domestic source of raw
material for the steel industry. Taconite processing plants use large quantities of electric power to grind the iron-bearing rock, and agglomerate and pelletize
the iron particles into taconite pellets.

Minnesota Power’s taconite customers are capable of producing approximately 41 million tons of taconite pellets annually. Taconite pellets produced in
Minnesota are primarily shipped to North American steel making facilities that are part of the integrated steel industry, which continue to lead the world in
environmental  performance  among  steelmaking  countries.  According  to  the  U.S.  Department  of  Energy,  steel  production  in  the  U.S.  is  the  most  energy
efficient of any major steel producing country. Steel produced from these North American facilities is used primarily in the manufacture of automobiles,
appliances,  tubular  applications  for  all  industries,  and  in  the  construction  industry.  Steel  is  also  a  critical  component  of  the  clean  energy  transformation
underway today. The demand for more renewable energy and the need for additional infrastructure to transport green energy from the point of generation to
the end user both require steel. Historically, less than 10 percent of Minnesota taconite production has been exported outside of North America.

There has been a general historical correlation between U.S. steel production and Minnesota taconite production. The American Iron and Steel Institute, an
association  of  North  American  steel  producers,  reported  that  U.S.  raw  steel  production  operated  at  approximately  82  percent  of  capacity  in  2021  (68
percent in 2020 and 80 percent in 2019). The World Steel Association, an association of steel producers, national and regional steel industry associations,
and steel research institutes representing approximately 85 percent of world steel production, projected U.S. steel consumption in 2022 will increase by
approximately 6 percent compared to 2021.

The following table reflects Minnesota Power’s taconite customers’ production levels for the past ten years:

* Preliminary data from the Minnesota Department of Revenue.

Minnesota  Power’s  taconite  customers  may  experience  annual  variations  in  production  levels  due  to  such  factors  as  economic  conditions,  short-term
demand changes or maintenance outages. We estimate that a one million ton change in Minnesota Power’s taconite customers’ production would impact
our annual earnings per share by approximately $0.04, net of expected power marketing sales at current prices. Changes in wholesale electric prices or
customer  contractual  demand  nominations  could  impact  this  estimate.  Minnesota  Power  proactively  sells  power  in  the  wholesale  power  markets  that  is
temporarily  not  required  by  industrial  customers  to  optimize  the  value  of  its  generating  facilities.  Long-term  reductions  in  taconite  production  or  a
permanent shut down of a taconite customer may lead Minnesota Power to file a general rate case to recover lost revenue.

In addition to serving the taconite industry, Minnesota Power serves a number of customers in the paper, pulp and secondary wood products industry, which
represented 702 million kWh, or 10 percent of total industrial customer kWh sales in 2021. Minnesota Power also has an agreement to provide steam for
one paper and pulp customer for use in the customer’s operations. The four major paper and pulp mills we serve reported operating at lower levels in 2021
compared to 2020. Verso Corporation indefinitely idled its paper mill in Duluth, Minnesota, which it subsequently sold to ST Paper in May 2021. (See
Outlook – Regulated Operations – Industrial Customers and Prospective Additional Load – Paper, Pulp and Secondary Wood Products – Verso Corporation
and ST Paper.)

Large Power Customer Contracts. Minnesota Power had eight Large Power Customer contracts as of December 31, 2021, each serving requirements of
10 MW or more of customer load; however, Minnesota Power and Verso Corporation mutually agreed to resolve the outstanding commitments under the
contract in January 2022. The customers as of December 31, 2021 consisted of six taconite facilities owned by Cliffs and USS Corporation as well as four
paper and pulp mills. Certain facilities with common ownership are served under combined contracts.

REGULATED OPERATIONS (Continued)
Large Power Customer Contracts (Continued)

Large Power Customer contracts require Minnesota Power to have a certain amount of generating capacity available. In turn, each Large Power Customer
is  required  to  pay  a  minimum  monthly  demand  charge  that  covers  the  fixed  costs  associated  with  having  this  capacity  available  to  serve  the  customer,
including a return on common equity. Most contracts allow customers to establish the level of megawatts subject to a demand charge on a three to four-
month basis and require that a portion of their megawatt needs be committed on a take-or-pay basis for at least a portion of the term of the agreement. In
addition  to  the  demand  charge,  each  Large  Power  Customer  is  billed  an  energy  charge  for  each  kWh  used  that  recovers  the  variable  costs  incurred  in
generating electricity. Five of the Large Power Customer contracts have interruptible service which provides a discounted demand rate in exchange for the
ability to interrupt the customers during system emergencies. Minnesota Power also provides incremental production service for customer demand levels
above the contractual take-or-pay levels. There is no demand charge for this service and energy is priced at an increment above Minnesota Power’s cost.
Incremental production service is interruptible.

All contracts with Large Power Customers continue past the contract termination date unless the required advance notice of cancellation has been given.
The required advance notice of cancellation varies from two to four years. Such contracts reduce the impact on earnings that otherwise would result from
significant reductions in kWh sales to such customers. Large Power Customers are required to take all of their purchased electric service requirements from
Minnesota  Power  for  the  duration  of  their  contracts.  The  rates  and  corresponding  revenue  associated  with  capacity  and  energy  provided  under  these
contracts are subject to change through the same regulatory process governing all retail electric rates. (See Regulatory Matters – Electric Rates.)

Minnesota Power, as permitted by the MPUC, requires its taconite-producing Large Power Customers to pay weekly for electric usage based on monthly
energy  usage  estimates.  These  customers  receive  estimated  bills  or  make  weekly  prepayments  based  on  Minnesota  Power’s  estimate  of  the  customer’s
energy usage, forecasted energy prices and fuel adjustment clause estimates. Minnesota Power’s taconite‑producing Large Power Customers have generally
predictable energy usage on a week-to-week basis and any differences that occur are trued-up the following month.

REGULATED OPERATIONS (Continued)

Residential and Commercial Customers. In 2021, residential and commercial customers represented 16 percent of total regulated utility kWh sales.

Municipal Customers. In 2021, municipal customers represented 4 percent of total regulated utility kWh sales.

Minnesota  Power’s  wholesale  electric  contracts  with  15  non-affiliated  municipal  customers  in  Minnesota  have  termination  dates  ranging  from  2024
through 2037, with a majority of contracts effective through 2029. Two of the wholesale contracts include a termination clause requiring a three-year notice
to terminate. (See Note 4. Regulatory Matters.)

Other Power Suppliers. The Company also enters into off-system sales with Other Power Suppliers. These sales are at market‑based prices into the MISO
market on a daily basis or through bilateral agreements of various durations.

Our PSAs are detailed in Note 8. Commitments, Guarantees and Contingencies, with additional disclosure provided in the following paragraphs.

Basin PSAs.  Minnesota  Power  had  an  agreement  to  sell  100  MW  of  capacity  and  energy  to  Basin  for  a  ten-year  period  which  expired  in  April  2020.
Minnesota Power has two additional agreements to sell capacity to Basin at fixed prices. (See Note 8. Commitments, Guarantees and Contingencies.)

Minnkota Power PSA. Minnesota Power has a PSA with Minnkota Power where Minnesota Power is selling a portion of its entitlement from Square Butte
to Minnkota Power, resulting in Minnkota Power’s net entitlement increasing and Minnesota Power’s net entitlement decreasing until Minnesota Power’s
share is eliminated at the end of 2025. Of Minnesota Power’s 50 percent output entitlement, it sold approximately 28 percent to Minnkota Power in 2021
(28 percent in 2020 and in 2019). Minnkota Power’s net entitlement increases to approximately 32 percent in 2022, 37 percent in 2023, 41 percent in 2024,
46 percent in 2025 and 50 percent in 2026. (See Power Supply – Long-Term Purchased Power.)

Silver Bay Power PSA. In 2016, Minnesota Power and Silver Bay Power entered into a PSA through 2031. Silver Bay Power supplies approximately 90
MW of load to Northshore Mining, an affiliate of Silver Bay Power, which had previously been served predominately through self-generation by Silver
Bay Power. Minnesota Power now supplies the full energy requirements for Silver Bay Power.

Seasonality

The operations of our industrial customers, which make up a large portion of our electric sales, are not typically subject to significant seasonal variations.
(See Electric  Sales  /  Customers.)  As  a  result,  Minnesota  Power  is  generally  not  subject  to  significant  seasonal  fluctuations  in  electric  sales;  however,
Minnesota Power and SWL&P electric and natural gas sales to other customers may be affected by seasonal differences in weather. In general, peak electric
sales occur in the winter and summer months with fewer electric sales in the spring and fall months. Peak sales of natural gas generally occur in the winter
months. Additionally, our regulated utilities have historically generated fewer sales and less revenue when weather conditions are milder in the winter and
summer.

Power Supply

In  order  to  meet  its  customers’  electric  requirements,  Minnesota  Power  utilizes  a  mix  of  its  own  generation  and  purchased  power.  As  of  December  31,
2021, approximately 50 percent of Minnesota Power’s power supply was provided by renewable energy sources. This was enabled by the completion of the
250 MW Nobles 2 wind energy facility in December 2020 and the GNTL in June 2020, which is used to deliver 250 MW of hydroelectric energy from
Manitoba Hydro. Minnesota Power’s remaining operating coal-fired facilities are Boswell Units 3 and 4, which Minnesota Power proposed in its latest IRP
to retire by 2030 and be coal-free by 2035, respectively. (See Regulatory Matters.) The following table reflects Minnesota Power’s generating capabilities
as of December 31, 2021, and total electrical supply for 2021. Minnesota Power had an annual net peak load of 1,557 MW on July 26, 2021.

Fuel.  Minnesota  Power  purchases  low-sulfur,  sub-bituminous  coal  from  the  Powder  River  Basin  region  located  in  Montana  and  Wyoming.  Coal
consumption in 2021 for electric generation at Minnesota Power’s coal-fired generating stations was 2.7 million tons (2.2 million tons in 2020; 2.5 million
tons in 2019). As of December 31, 2021, Minnesota Power had coal inventories of 0.4 million tons (0.8 million tons as of December 31, 2020). Minnesota
Power has coal supply agreements providing for the purchase of a significant portion of its coal requirements through December 2022. In 2022, Minnesota
Power expects to obtain coal under these coal supply agreements and in the spot market. Minnesota Power continues to explore other future coal supply
options and believes that adequate supplies of low-sulfur, sub-bituminous coal will continue to be available.

Minnesota Power also has coal transportation agreements in place for the delivery of a significant portion of its coal requirements through December 2024.
The costs of fuel and related transportation costs for Minnesota Power’s generation are recoverable from Minnesota Power’s utility customers through the
fuel adjustment clause.

Long-Term Purchased Power. Minnesota Power has contracts to purchase capacity and energy from various entities, including output from certain coal,
wind, hydro and solar generating facilities.

Our PPAs are detailed in Note 8. Commitments, Guarantees and Contingencies, with additional disclosure provided in the following paragraph.

Square Butte PPA. Under the PPA with Square Butte that extends through 2026, Minnesota Power is entitled to 50 percent of the output of Square Butte’s
455 MW coal-fired generating unit. (See Note 8. Commitments, Guarantees and Contingencies.) BNI Energy mines and sells lignite coal to Square Butte.
This lignite supply is sufficient to provide fuel for the anticipated useful life of the generating unit. Square Butte’s cost of lignite consumed in 2021 was
approximately $1.94 per MBtu ($1.75 per MBtu in 2020; $1.88 per MBtu in 2019). (See Electric Sales / Customers – Minnkota Power PSA.)

Manitoba Hydro. Minnesota Power has three long-term PPAs with Manitoba Hydro. Under the first PPA, Minnesota Power is purchasing surplus energy
through April 2022. This energy-only agreement primarily consists of surplus hydro energy on Manitoba Hydro’s system that is delivered to Minnesota
Power on a non-firm basis. Under this agreement, Minnesota Power will purchase at least one million MWh of energy over the contract term. The second
PPA provides for Minnesota Power to purchase 250 MW of capacity and energy from Manitoba Hydro through May 2035. The third PPA provides for
Minnesota Power to purchase up to 133 MW of energy from Manitoba Hydro through June 2040.

Transmission and Distribution

We  have  electric  transmission  and  distribution  lines  of  500  kV  (232  miles),  345  kV  (241  miles),  250  kV  (466  miles),  230  kV  (715  miles),  161  kV  (43
miles), 138 kV (130 miles), 115 kV (1,248 miles) and less than 115 kV (6,390 miles). We own and operate 159 substations with a total capacity of 10,086
megavoltamperes. Some of our transmission and distribution lines interconnect with other utilities.

Great  Northern  Transmission  Line.  As  a  condition  of  the  250  MW  long-term  PPA  entered  into  with  Manitoba  Hydro,  construction  of  additional
transmission capacity was required. As a result, Minnesota Power constructed the GNTL, an approximately 220‑mile 500-kV transmission line between
Manitoba  and  Minnesota’s  Iron  Range  that  was  proposed  by  Minnesota  Power  and  Manitoba  Hydro  in  order  to  strengthen  the  electric  grid,  enhance
regional reliability and promote a greater exchange of sustainable energy. In June 2020, Minnesota Power placed the GNTL into service with project costs
of  approximately  $310  million  incurred  by  Minnesota  Power.  Total  project  costs,  including  those  costs  contributed  by  a  subsidiary  of  Manitoba  Hydro,
totaled approximately $660 million. The 250 MW PPA with Manitoba Hydro commenced when the GNTL was placed into service.

Investment in ATC

Our wholly-owned subsidiary, ALLETE Transmission Holdings, owns approximately 8 percent of ATC, a Wisconsin-based utility that owns and maintains
electric transmission assets in portions of Wisconsin, Michigan, Minnesota and Illinois. We account for our investment in ATC under the equity method of
accounting. As of December 31 2021, our equity investment in ATC was $154.5 million ($149.0 million as of December 31, 2020). (See Note 5. Equity
Investments.)

ATC’s authorized return on equity is 10.02 percent, or 10.52 percent including an incentive adder for participation in a regional transmission organization,
based on a 2020 FERC order that granted rehearing of a 2019 FERC order. These FERC orders are subject to various outstanding legal challenges related
to  the  refund  period  ordered  by  the  FERC.  If  these  legal  challenges  are  successful,  ATC  may  be  required  to  provide  refunds  to  its  customers  of  up  to
approximately $65 million of which our share would be approximately $5 million pre-tax. In addition, the FERC issued a Notice of Proposed Rulemaking
in April 2021 proposing to limit the 50 basis point incentive adder for participation in a regional transmission organization to only the first three years of
membership in such an organization. If this proposal is adopted, our equity in earnings from ATC would be reduced by approximately $1 million pre-tax
annually.

ATC’s  10-year  transmission  assessment,  which  covers  the  years  2021  through  2030,  identifies  a  need  for  between  $3.5  billion  and  $4.2  billion  in
transmission system investments. These investments by ATC, if undertaken, are expected to be funded through a combination of internally generated cash,
debt and investor contributions. As opportunities arise, we plan to make additional investments in ATC through general capital calls based upon our pro
rata ownership interest in ATC.

Properties

Our Regulated Operations businesses own office and service buildings, an energy control center, repair shops, electric plants, transmission facilities and
storerooms  in  various  localities  in  Minnesota,  Wisconsin  and  North  Dakota.  All  of  the  electric  plants  are  subject  to  mortgages,  which  collateralize  the
outstanding first mortgage bonds of Minnesota Power and SWL&P. Most of the generating plants and substations are located on real property owned by
Minnesota Power or SWL&P, subject to the lien of a mortgage, whereas most of the transmission and distribution lines are located on real property owned
by others with appropriate easement rights or necessary permits from governmental authorities. WPPI Energy owns 20 percent of Boswell Unit 4. WPPI
Energy has the right to use our transmission line facilities to transport its share of Boswell generation. (See Note 3. Jointly-Owned Facilities and Assets.)

Regulatory Matters

We  are  subject  to  the  jurisdiction  of  various  regulatory  authorities  and  other  organizations.  Regulatory  matters  and  proceedings  are  detailed  in  Note  4.
Regulatory Matters, with a summary included in the following paragraphs.

Electric Rates. All rates and contract terms in our Regulated Operations are subject to approval by applicable regulatory authorities. Minnesota Power and
SWL&P design their retail electric service rates based on cost of service studies under which allocations are made to the various classes of customers as
approved by the MPUC or the PSCW. Nearly all retail sales include billing adjustment clauses, which may adjust electric service rates for changes in the
cost of fuel and purchased energy, recovery of current and deferred conservation improvement program expenditures and recovery of certain transmission,
renewable and environmental investments.

Minnesota Public Utilities Commission. The MPUC has regulatory authority over Minnesota Power’s retail service area in Minnesota, retail rates, retail
services, capital structure, issuance of securities and other matters. Minnesota Power’s current retail rates are based on a 2018 MPUC retail rate order that
allows for a 9.25 percent return on common equity and a 53.81 percent equity ratio. The resolution of Minnesota Power’s 2020 general rate case did not
change  the  allowed  return  on  equity  or  equity  ratio.  (See  2020  Minnesota  General  Rate  Case.)  As  authorized  by  the  MPUC,  Minnesota  Power  also
recognizes revenue under cost recovery riders for transmission and renewable investments.

2020 Minnesota General Rate Case. In November 2019, Minnesota Power filed a retail rate increase request with the MPUC seeking an average increase
of  approximately  10.6  percent  for  retail  customers.  The  rate  filing  sought  a  return  on  equity  of  10.05  percent  and  a  53.81  percent  equity  ratio.  On  an
annualized basis, the requested final rate increase would have generated approximately $66 million in additional revenue. In December 2019 orders, the
MPUC accepted the filing as complete and authorized an annual interim rate increase of $36.1 million beginning January 1, 2020.

ALLETE, Inc. 2021 Form 10-K

REGULATED OPERATIONS (Continued)
Regulatory Matters (Continued)

In April 2020, Minnesota Power filed a request with the MPUC that proposed a resolution of Minnesota Power’s 2020 general rate case. Key components
of our proposal included removing the power marketing margin credit in base rates and reflecting actual power marketing margins in the fuel adjustment
clause effective May 1, 2020; refunding to customers interim rates collected through April 2020; increasing customer rates 4.1 percent compared to the 5.8
percent increase reflected in interim rates; and a provision that Minnesota Power would not file another rate case until at least November 1, 2021, unless
certain events occur. In a June 2020 order, the MPUC approved Minnesota Power’s petition and proposal to resolve and withdraw the general rate case.
Effective May 1, 2020, customer rates were set at an increase of 4.1 percent with the removal of the power marketing margin credit from base rates. Actual
power marketing margins will be reflected in the fuel adjustment clause. Reserves for interim rates of $11.7 million were recorded in the second quarter of
2020 and refunded in the third and fourth quarters of 2020.

2022  Minnesota  General  Rate  Case.  On  November  1,  2021,  Minnesota  Power  filed  a  retail  rate  increase  request  with  the  MPUC  seeking  an  average
increase of approximately 18 percent for retail customers. The rate filing seeks a return on equity of 10.25 percent and a 53.81 percent equity ratio. On an
annualized basis, the requested final rate increase would generate approximately $108 million in additional revenue. In orders dated December 30, 2021,
the  MPUC  accepted  the  filing  as  complete  and  authorized  an  annual  interim  rate  increase  beginning  January  1,  2022,  with  approximately  $80  million
expected to be collected in cash and approximately $8 million of interim rates for residential customers deferred with a final determination on recovery at
the end of the rate case.

Minnesota Power Land Sales. In August 2020, Minnesota Power filed a petition with the MPUC for approval to sell land that surrounds several reservoirs
on  its  hydroelectric  system  and  is  no  longer  required  to  maintain  its  operations.  The  land  has  an  estimated  value  of  approximately  $100  million,  and
Minnesota Power proposed to credit ratepayers the net proceeds from the sales in a future rate case or through its renewable resources rider to mitigate
future rate increases. In an order dated November 18, 2021, the MPUC authorized the land sales and directed the net proceeds to be refunded to ratepayers
subject to certain conditions and required compliance filings.

2021 Integrated Resource Plan. On February 1, 2021, Minnesota Power filed its latest IRP with the MPUC, which outlines its clean-energy transition plans
through 2035. These plans include expanding its renewable energy supply to 70 percent by 2030, achieving coal-free operations at its facilities by 2035,
and  investing  in  a  resilient  and  flexible  transmission  and  distribution  grid.  Minnesota  Power  has  also  set  a  target  to  achieve  an  80  percent  reduction  in
carbon emissions by 2035 compared to 2005 levels. As part of these plans, Minnesota Power anticipates adding approximately 400 MW of new wind and
solar energy resources, retiring Boswell Unit 3 by 2030 and transforming Boswell Unit 4 to be coal-free by 2035. Minnesota Power’s plans recognize that
advances in technology will play a significant role in completing its transition to carbon-free energy supply, reliably and affordably. A final decision on the
IRP is expected in the second half of 2022.

Minnesota  Power  has  a  vision  to  deliver  100  percent  carbon-free  energy  to  customers  by  2050,  continuing  its  commitment  to  climate,  customers  and
communities through its EnergyForward strategy. This vision builds on Minnesota Power’s recent achievement of now providing 50 percent renewable
energy to its customers.

Public Service Commission of Wisconsin. The PSCW has regulatory authority over SWL&P’s retail sales of electricity, natural gas and water, issuances
of securities and other matters. SWL&P’s current retail rates are based on a December 2018 order that allows for a return on equity of 10.4 percent and a
55.0 percent equity ratio. The PSCW had directed SWL&P to file its next general rate case in 2020; however, the PSCW granted an extension request made
by SWL&P to delay filing its next general rate case until on or before December 20, 2022. SWL&P requested the extension primarily due to impacts of the
COVID-19 pandemic.

North Dakota Public Service Commission. The NDPSC has jurisdiction over site and route permitting of generation and transmission facilities in North
Dakota.

Federal Energy Regulatory Commission. The FERC has jurisdiction over the licensing of hydroelectric projects, the establishment of rates and charges
for  transmission  of  electricity  in  interstate  commerce,  electricity  sold  at  wholesale  (including  the  rates  for  Minnesota  Power’s  municipal  and  wholesale
customers),  natural  gas  transportation,  certain  accounting  and  record‑keeping  practices,  certain  activities  of  our  regulated  utilities  and  the  operations  of
ATC. FERC jurisdiction also includes enforcement of NERC mandatory electric reliability standards. Violations of FERC rules are subject to enforcement
action by the FERC including financial penalties up to $1 million per day per violation.

REGULATED OPERATIONS (Continued)

Regional Organizations

Midcontinent  Independent  System  Operator,  Inc.  Minnesota  Power,  SWL&P  and  ATC  are  members  of  MISO,  a  regional  transmission  organization.
While  Minnesota  Power  and  SWL&P  retain  ownership  of  their  respective  transmission  assets,  their  transmission  networks  are  under  the  regional
operational  control  of  MISO.  Minnesota  Power  and  SWL&P  take  and  provide  transmission  service  under  the  MISO  open  access  transmission  tariff.  In
cooperation with stakeholders, MISO manages the delivery of electric power across 15 states and the Canadian province of Manitoba.

North American Electric Reliability Corporation. The NERC has been certified by the FERC as the national electric reliability organization. The NERC
ensures the reliability of the North American bulk power system. The NERC oversees six regional entities that establish requirements, approved by the
FERC,  for  reliable  operation  and  maintenance  of  power  generation  facilities  and  transmission  systems.  Minnesota  Power  is  subject  to  these  reliability
requirements and can incur significant penalties for non‑compliance.

Midwest Reliability Organization (MRO). Minnesota Power and ATC are members of the MRO, one of the six regional entities overseen by the NERC.
The MRO's primary responsibilities are to: ensure compliance with mandatory reliability standards by entities who own, operate or use the interconnected,
international bulk power system; conduct assessments of the grid's ability to meet electricity demand in the region; and analyze regional system events. The
MRO region spans the Canadian provinces of Saskatchewan and Manitoba, and all or parts of 16 states.

Minnesota Legislation

Renewable Energy. Minnesota law requires 25 percent of electric utilities’ applicable retail and municipal energy sales in Minnesota to be from renewable
energy  sources  by  2025.  Minnesota  law  also  requires  Minnesota  Power  to  meet  interim  milestones  including  20  percent  by  2020.  The  law  allows  the
MPUC to modify or delay meeting a milestone if implementation will cause significant ratepayer cost or technical reliability issues. If a utility is not in
compliance  with  a  milestone,  the  MPUC  may  order  the  utility  to  construct  facilities,  purchase  renewable  energy  or  purchase  renewable  energy  credits.
Minnesota Power has exceeded the interim milestone requirements to date.

As  of  December  31,  2021,  approximately  50  percent  of  Minnesota  Power’s  power  supply  was  provided  by  renewable  energy  sources.  (See  Item  7.
Management’s Discussion and Analysis of Financial Condition and Results of Operations – Outlook – EnergyForward.)

Minnesota  Solar  Energy  Standard.  Minnesota  law  requires  at  least  1.5  percent  of  total  retail  electric  sales,  excluding  sales  to  certain  customers,  to  be
generated by solar energy. At least 10 percent of the 1.5 percent mandate must be met by solar energy generated by or procured from solar photovoltaic
devices with a nameplate capacity of 40 kW or less and community solar garden subscriptions. Minnesota Power has met both parts of the solar mandate to
date.

Competition

Retail electric energy sales in Minnesota and Wisconsin are made to customers in assigned service territories. As a result, most retail electric customers in
Minnesota do not have the ability to choose their electric supplier. Large energy users of 2 MW and above that are located outside of a municipality are
allowed to choose a supplier upon MPUC approval. Minnesota Power served 8 Large Power Customers under contracts of at least 10 MW in 2021, none of
which have engaged in a competitive rate process. (See Electric Sales / Customers.) No other large commercial or small industrial customers in Minnesota
Power’s service territory have sought a provider outside Minnesota Power’s service territory. Retail electric and natural gas customers in Wisconsin do not
have the ability to choose their energy supplier. In both states, however, electricity may compete with other forms of energy. Customers may also choose to
generate their own electricity, or substitute other forms of energy for their manufacturing processes.

In 2021, 4 percent of total regulated utility kWh sales were to municipal customers in Minnesota. These customers have the right to seek an energy supply
from any wholesale electric service provider upon contract expiration. Minnesota Power’s wholesale electric contract with the Nashwauk Public Utilities
Commission  was  extended  in  2020  and  is  effective  through  December  31,  2037.  Minnesota  Power’s  wholesale  electric  contracts  with  14  non-affiliated
municipal customers are effective through varying dates ranging from 2024 through 2029. (See Electric Sales / Customers.)

REGULATED OPERATIONS (Continued)
Competition (Continued)

The  FERC  has  continued  with  its  efforts  to  promote  a  competitive  wholesale  market  through  open-access  electric  transmission  and  other  means.  As  a
result, our electric sales to Other Power Suppliers and our purchases to supply our retail and wholesale load are made in a competitive market.

Franchises

Minnesota Power holds franchises to construct and maintain an electric distribution and transmission system in 95 cities. The remaining cities, villages and
towns served by Minnesota Power do not require a franchise to operate. SWL&P serves customers under electric, natural gas or water franchises in 1 city
and 14 villages and towns.

ALLETE CLEAN ENERGY

ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects. ALLETE Clean Energy currently owns and
operates,  in  seven  states,  more  than  1,300  MW  of  nameplate  capacity  wind  energy  generation  that  is  contracted  under  PSAs  of  various  durations.  In
addition, ALLETE Clean Energy currently has approximately 200 MW of wind energy facilities under contract to be sold to others. ALLETE Clean Energy
also  engages  in  the  development  of  wind  energy  facilities  to  operate  under  long-term  PSAs  or  for  sale  to  others  upon  completion.  (See  Item  7.
Management’s Discussion and Analysis of Financial Condition and Results of Operations – Outlook – ALLETE Clean Energy.)

ALLETE Clean Energy believes the market for renewable energy in North America is robust, driven by several factors including environmental regulation,
tax  incentives  such  as  the  extension  of  production  tax  credit  and  investment  tax  credits,  societal  expectations  and  continual  technology  advances.  State
renewable portfolio standards, state or federal regulations to limit GHG emissions and the extension of production tax credit and investment tax credits are
examples of environmental regulation or public policy that we believe will drive renewable energy development.

ALLETE Clean Energy’s strategy includes the safe, reliable, optimal and profitable operation of its existing facilities. This includes a strong safety culture,
the continuous pursuit of operational efficiencies at existing facilities and cost controls. ALLETE Clean Energy generally acquires facilities in liquid power
markets and its strategy includes the exploration of PSA extensions upon expiration of existing contracts, production tax credit requalification of existing
facilities or the sale of facilities.

ALLETE CLEAN ENERGY (Continued)

ALLETE Clean Energy manages risk by having a diverse portfolio of assets, which includes PSA expiration, technology and geographic diversity. The
current  operating  portfolio  is  subject  to  typical  variations  in  seasonal  wind  with  higher  wind  resources  typically  available  in  the  winter  months.  The
majority  of  its  planned  maintenance  leverages  this  seasonality  and  is  performed  during  lower  wind  periods.  ALLETE  Clean  Energy’s  current  operating

(a) The PSA expiration assumes the exercise of four one-year renewal options that ALLETE Clean Energy has the sole right to exercise.

The  majority  of  ALLETE  Clean  Energy’s  wind  operations  are  located  on  real  property  owned  by  others  with  easement  rights  or  necessary  consents  of
governmental authorities. One of ALLETE Clean Energy’s wind energy facilities is encumbered by liens against its assets securing financing. ALLETE
Clean  Energy’s  Glen  Ullin,  South  Peak,  Diamond  Spring  and  Caddo  wind  energy  facilities  are  subject  to  tax  equity  financing  structures.  (See  Note  1.
Operations and Significant Accounting Policies.)

U.S. WATER SERVICES

U.S.  Water  Services  provided  integrated  water  management  for  industry  by  combining  chemical,  equipment,  engineering  and  service  for  customized
solutions to reduce water and energy usage, and improve efficiency. In March 2019, the Company sold U.S. Water Services to a subsidiary of Kurita Water
Industries Ltd. pursuant to a stock purchase agreement for approximately $270 million in cash, net of transaction costs and cash retained. The Company
recognized a gain on the sale of U.S. Water Services of $13.2 million after-tax in 2019. ALLETE used the proceeds from the sale of U.S. Water Services to
reinvest in growth initiatives at our Regulated Operations and ALLETE Clean Energy.

CORPORATE AND OTHER

BNI Energy

BNI Energy is a supplier of lignite coal in North Dakota, producing approximately 4 million tons annually and has an estimated 650 million tons of lignite
coal reserves. Two electric generating cooperatives, Minnkota Power and Square Butte, consume virtually all of BNI Energy’s production of lignite under
cost-plus fixed fee coal supply agreements extending through December 31, 2037. (See Item 1. Business – Regulated Operations – Power Supply – Long-
Term Purchased Power and Note 8. Commitments, Guarantees and Contingencies.) The mining process disturbs and reclaims between 200 and 250 acres
per year. Laws require that the reclaimed land be at least as productive as it was prior to mining. As of December 31, 2021, BNI Energy’s total reclamation
liability is estimated at $70.7 million and is included in Other Non-Current Liabilities on the Consolidated Balance Sheet. These costs are included in the
cost-plus fixed fee contract, for which an asset reclamation cost receivable was included in Other Non-Current Assets on the Consolidated Balance Sheet.
The asset reclamation obligation is guaranteed by surety bonds and a letter of credit. (See Note 8. Commitments, Guarantees and Contingencies.)

CORPORATE AND OTHER (Continued)

Investment in Nobles 2

Our subsidiary, ALLETE South Wind, owns a 49 percent equity interest in Nobles 2, the entity that owns and operates a 250 MW wind energy facility in
southwestern  Minnesota  pursuant  to  a  20-year  PPA  with  Minnesota  Power.  As  of  December  31,  2021,  our  equity  investment  in  Nobles  2  was  $163.5
million ($152.2 million at December 31, 2020). (See Note 5. Equity Investments.)

South Shore Energy

South  Shore  Energy,  ALLETE’s  non-rate  regulated,  Wisconsin  subsidiary,  is  developing  NTEC,  an  approximately  600  MW  proposed  combined-cycle
natural  gas-fired  generating  facility  to  be  built  in  Superior,  Wisconsin,  which  will  be  jointly  owned  by  Dairyland  Power  Cooperative,  Basin  and  South
Shore Energy. Minnesota Power is expected to purchase approximately 20 percent of the facility's output starting in 2025 pursuant to a capacity dedication
agreement. Construction of NTEC is subject to obtaining additional permits from local, state and federal authorities. The total project cost is estimated to
be approximately $700 million, of which South Shore Energy’s portion is expected to be approximately $150 million. South Shore Energy’s portion of
NTEC project costs incurred through December 31, 2021, is approximately $5 million.

On  October  1,  2021,  South  Shore  Energy  sold  a  portion  of  its  undivided  ownership  interest  in  NTEC  for  approximately  $20  million  representing
reimbursement of current costs plus a fee for prior development costs and risks incurred. Following the transaction, South Shore Energy now owns a 20
percent  undivided  ownership  interest  in  NTEC,  Basin  owns  a  30  percent  undivided  ownership  interest  in  NTEC  and  Dairyland  Power  Cooperative
continues to own a 50 percent undivided ownership interest in NTEC. The closing of the transaction resulted in the recognition of an approximately $8.5
million after-tax gain recorded in Corporate and Other in the fourth quarter of 2021, related to prior development costs and risks incurred.

ALLETE Properties

ALLETE  Properties  represents  our  legacy  Florida  real  estate  investment.  ALLETE  Properties’  major  project  in  Florida  is  Town  Center  at  Palm  Coast,
which consists of approximately 500 acres of land as well as various residential units and non-residential square footage. In addition to the Town Center at
Palm Coast project, ALLETE Properties has approximately 500 acres of other land available for sale. (See Item 7. Management’s Discussion and Analysis
of Financial Condition and Results of Operations – Outlook – Corporate and Other – ALLETE Properties.)

Seller  Financing.  ALLETE  Properties  occasionally  provides  seller  financing  to  qualified  buyers.  As  of  December  31,  2021,  outstanding  finance
receivables  were  $7.6  million,  net  of  reserves,  with  maturities  through  2026.  These  finance  receivables  accrue  interest  at  market-based  rates  and  are
collateralized by the financed properties.

Regulation.  A  substantial  portion  of  our  development  properties  in  Florida  are  subject  to  federal,  state  and  local  regulations,  and  restrictions  that  may
impose significant costs or limitations on our ability to develop the properties. Much of our property is vacant land and some is located in areas where
development may affect the natural habitats of various protected wildlife species or in sensitive environmental areas such as wetlands.

Non-Rate Base Generation and Miscellaneous

Corporate and Other also includes other business development and corporate expenditures, unallocated interest expense, a small amount of non-rate base
generation, approximately 4,000 acres of land in Minnesota, and earnings on cash and investments.

As of December 31, 2021, non-rate base generation consists  of  29  MW  of  natural  gas  and  hydro  generation  at  Rapids  Energy  Center  in  Grand  Rapids,
Minnesota, which is primarily dedicated to the needs of one customer, UPM Blandin.

ENVIRONMENTAL MATTERS

Our businesses are subject to regulation of environmental matters by various federal, state and local authorities. A number of regulatory changes to the
Clean Air Act, the Clean Water Act and various waste management requirements have been promulgated by both the EPA and state authorities over the
past several years. Minnesota Power’s facilities are subject to additional requirements under many of these regulations. Minnesota Power is reshaping its
generation portfolio, over time, to reduce its reliance on coal, has installed cost-effective emission control technology, and advocates for sound science and
policy during rulemaking implementation.

We consider our businesses to be in substantial compliance with currently applicable environmental regulations and believe all necessary permits have been
obtained.  We  anticipate  that  with  many  state  and  federal  environmental  regulations  and  requirements  finalized,  or  to  be  finalized  in  the  near  future,
potential expenditures for future environmental matters may be material and require significant capital investments. Minnesota Power has evaluated various
environmental compliance scenarios using possible outcomes of environmental regulations to project power supply trends and impacts on customers.

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. Accruals are adjusted as assessment
and remediation efforts progress, or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in
the  Consolidated  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 expensed unless recoverable in rates from customers. (See Note 8. Commitments, Guarantees and
Contingencies.)

HUMAN CAPITAL MANAGEMENT

The Company’s key human capital management objectives are to attract, recognize and retain high quality talent, align with strategic business objectives
and support the Company’s values. To support these objectives, the Company’s programs are designed to develop talent; reward and support employees
through  competitive  compensation  programs  and  benefit  plans;  enhance  the  Company’s  culture  through  efforts  aimed  at  making  the  workplace  more
engaging, safe and inclusive; and acquire talent and leverage internal opportunities to create a high-performing, diverse workforce. Our management and
Board of Directors play key roles in reviewing and overseeing our human capital practices.

As  of  December  31,  2021,  ALLETE  had  1,365  employees,  of  which  1,340  were  full-time.  Minnesota  Power  and  SWL&P  have  an  aggregate  of  469
employees covered under collective bargaining agreements, of which most are members of the International Brotherhood of Electrical Workers (IBEW)
Local 31. The current labor agreements with IBEW Local 31 expire on April 30, 2023 for Minnesota Power and January 31, 2024 for SWL&P. BNI Energy
has 127 employees that are members of IBEW Local 1593. The current labor agreement with IBEW Local 1593 expires on March 31, 2023.

Integrity. Integrity is a foundational, shared value at ALLETE, is important to ALLETE’s business and operations, and enables our success. The Company
has a written Code of Ethics that applies to all of our employees.

Health and Safety. The  success  of  our  business  is  fundamentally  connected  to  the  well-being  of  our  people.  We  continue  to  respond  to  the  COVID-19
pandemic by taking steps to mitigate the potential risks to us posed by its transmission and have implemented company-wide business continuity plans in
response to the pandemic. These plans guide our response, business continuity, and the precautionary measures we are taking on behalf of employees and
the public.

HUMAN CAPITAL MANAGEMENT (Continued)

Zero  Injury  Culture. Our  journey  to  Zero  Injury  starts  with  a  culture  that  is  open  and  transparent.  We  encourage  all  employees  to  report  injuries,  near
misses, and good catches, so that we can learn and share with others throughout the Company in an effort to improve safety performance. Leaders have
regular safety conversations with employees, where the data learned from the conversations is examined, shared with the ALLETE safety strategy team and
used to improve the Company’s safety programs. To monitor progress, the Company uses leading and lagging indicators to analyze injury trends, safety
participation and other data to make better decision on safety practices.

Talent Attraction, Retention and Development. For more than a century, ALLETE has been successful because of our ability to attract and retain high-
quality people who demonstrate our shared values. We engage in workforce planning, and succession planning, while building a robust talent pipeline and
monitoring turnover.

We recognize and support the growth and development of our employees and offer opportunities to participate in internal and external learning programs.
Our internal talent development programs provide employees with the resources they need to develop proficiency in their role, help achieve their career
goals and build leadership skills. We are focusing initiatives on programs to expand the diversity of new hires and updating on-the-job trainings—including
apprenticeships  and  scholarships  aimed  at  bridging  opportunity  gaps—as  we  recognize  the  importance  of  a  strong  talent  pipeline.  In  addition  to  role
specific training, targeted training also includes respect in the workplace, cyber awareness, safety, integrity and leadership development.

Compensation and Benefits. Our competitive compensation package gives employees flexibility, choices and opportunities. Competitive compensation is
important for the Company to attract and retain a qualified workforce to successfully manage our business and achieve our business objectives. We also
strive to ensure pay equity amongst diverse employees performing equal or substantially similar work. Periodically, we review the median pay of our male
and female employees as well as employees from diverse backgrounds.

Diversity, Equity and Inclusion. Increasing  staff  diversity  enriches  our  workforce  culture  at  ALLETE.  Our  employees  are  operating  in  an  increasingly
diverse society. In order to be accountable to our employees and stakeholders, we strive to have a workforce that reflects the diversity of the communities
we serve, promotes inclusivity and is equitable.

At ALLETE, we want to ensure that we have a workplace culture where we treat each other with fairness, dignity and respect. The Company has a respect
in the workplace initiative, which includes education as well as ongoing discussions focused on building respectful relationships and managing bias. We
continue our efforts in crafting a framework to strengthen ALLETE’s diversity, equity and inclusion efforts in the areas of: workforce, supply chain and
ALLETE as a community citizen. In 2021, ALLETE took tangible steps toward advancing diversity, equity and inclusion by continuing to raise awareness,
furthering intentional external relationships/partnerships, increasing supplier diversity, focus on underrepresented groups through grants/scholarships and
other Company and employee giving.

Yellow Ribbon Program. ALLETE and its subsidiaries are dedicated to supporting veterans, military members and their families. An employee effort grew
out of that spirit of commitment to veterans and led the state of Minnesota to designate ALLETE/Minnesota Power and ALLETE Clean Energy as Yellow
Ribbon  Companies.  The  mission  of  ALLETE’s  Yellow  Ribbon  Program  is  to  contribute  to  the  Company’s  unique  culture  by  proactively  recruiting  and
retaining the best and supporting an environment in which military-connected employees can thrive.

Item 1A. Risk Factors

The risks and uncertainties discussed below could materially affect our business operations, financial position, results of operations and cash flows, and
should be carefully considered by stakeholders. The risks and uncertainties in this section are not the only ones we face; additional risks and uncertainties
that  we  are  not  presently  aware  of,  or  that  we  currently  consider  immaterial,  may  also  affect  our  business  operations,  financial  position,  results  of
operations and cash flows. Accordingly, the risks described below should be carefully considered together with other information set forth in this report and
in future reports that we file with the SEC.

Regulated Operations Risks

Our  results  of  operations  could  be  negatively  impacted  if  our  taconite,  paper  and  pipeline  customers  experience  an  economic  downturn,  incur
work  stoppages,  fail  to  compete  effectively,  experience  decreased  demand,  fail  to  economically  obtain  raw  materials,  fail  to  renew  or  obtain
necessary permits, or experience a decline in prices for their product.

Minnesota Power’s Large Power Customers (see Item 1. Business – Regulated Operations – Electric Sales / Customers) and Silver Bay Power accounted
for 32 percent of our 2021 consolidated operating revenue (29 percent in 2020 and 30 percent in 2019) and 37 percent of Regulated Operations operating
revenue (34 percent in 2020 and 36 percent in 2019). Minnesota Power’s taconite customers, which are currently owned by only two entities at the end of
2021, accounted for approximately 28 percent of consolidated operating revenue and 32 percent of Regulated Operations operating revenue in 2021. These
customers are involved in cyclical industries that by their nature are adversely impacted by economic downturns and are subject to strong competition in
the  marketplace.  The  North  American  paper  and  pulp  industry  also  faces  declining  demand  due  to  the  impact  of  electronic  substitution  for  print  and
changing customer needs. As a result, certain paper and pulp customers have reduced their existing operations or idled facilities in recent years and have
pursued or are pursuing product changes in response to declining demand. Additionally, the taconite industry could be impacted by changing technology in
the steel industry such as the adoption of electric arc furnaces for steelmaking, which could result in declining demand for taconite and the electricity used
during its production.

Minnesota Power also serves two pipeline customers that accounted for 2 percent of our 2021 consolidated operating revenue (2 percent in 2020 and in
2019) and 2 percent of Regulated Operations revenue in 2021 (3 percent in 2020 and 3 percent in 2019). These customers are involved in an industry that is
seeing  increased  environmental  pressure  for  construction  of  new  or  expanded  pipeline  infrastructure  for  the  transportation  of  fossil  fuels.  Changes  in
regulatory rulings or permit proceedings could result in changes to operations of the pipeline network in our service territory.

Accordingly,  if  our  industrial  customers  experience  an  economic  downturn,  incur  a  work  stoppage  (including  strikes,  lock-outs  or  other  events),  fail  to
compete effectively, experience decreased demand, fail to economically obtain raw materials, fail to renew or obtain necessary permits, or experience a
decline in prices for their product, there could be adverse effects on their operations and, consequently, this could have a negative impact on our results of
operations as we are unable to remarket at similar prices the energy that would otherwise have been sold to such customers. These customers have also
been impacted by the ongoing COVID-19 pandemic. (See Entity-wide Risks.)

We  may  not  be  able  to  successfully  implement  our  strategic  objectives  of  growing  load  at  our  utilities  if  current  or  potential  industrial  or
municipal customers are unable to successfully implement expansion plans, including the inability to obtain necessary governmental permits and
approvals.

As part of our long-term strategy, we pursue new wholesale and retail loads in and around our service territories. Currently, there are several companies in
northeastern Minnesota that are in the process of developing natural resource-based projects that represent long-term growth potential and load diversity for
our  Regulated  Operations  businesses.  These  projects  may  include  construction  of  new  facilities  and  restarts  of  old  facilities,  both  of  which  require
permitting  and  approvals  to  be  obtained  before  the  projects  can  be  successfully  implemented.  If  a  project  does  not  obtain  any  necessary  governmental
(including environmental) permits and approvals or if these customers are unable to successfully implement expansion plans, our long-term strategy and
thus our results of operations could be adversely impacted.

Our businesses, investments and customers are subject to an extensive legal and regulatory framework under federal and state laws as well as
regulations imposed by other organizations that may have a negative impact on our business and results of operations.

Our  businesses,  investments  and  customers  are  subject  to  an  extensive  legal  and  regulatory  framework  imposed  under  federal  and  state  law  including
regulations administered by the FERC, MPUC, MPCA, PSCW, NDPSC and EPA as well as regulations administered by other organizations including the
NERC. These laws and regulations relate to allowed rates of return, capital structure, financings, rate and cost structure, acquisition and disposal of assets
and facilities, construction and operation of generation, transmission and distribution facilities (including the ongoing maintenance and reliable operation of
such facilities), recovery of purchased power costs and capital investments, approval of integrated resource plans and present or prospective wholesale and
retail competition, renewable portfolio standards that require utilities to obtain specified percentages of electric supply from eligible renewable generation
sources, among other things. Energy policy initiatives at the state or federal level could increase renewable portfolio standards or incentives for distributed
generation, municipal utility ownership, or local initiatives could introduce generation or distribution requirements that could change the current integrated
utility model. Our transmission systems and electric generation facilities are subject to the NERC mandatory reliability standards, including cybersecurity
standards. Compliance with these standards may lead to increased operating costs and capital expenditures which are subject to regulatory approval for
recovery. If it was determined that we were not in compliance with these mandatory reliability standards or other statutes, rules and orders, we could incur
substantial monetary penalties and other sanctions, which could adversely affect our results of operations.

These laws and regulations significantly influence our operations and may affect our ability to recover costs from our customers. We are required to have
numerous permits, licenses, approvals and certificates from the agencies and other organizations that regulate our business. We believe we have obtained
the necessary permits, licenses, approvals and certificates for our existing operations and that our business is conducted in accordance with applicable laws;
however, we are unable to predict the impact on our operating results from the future regulatory activities of any of these agencies and other organizations.
Changes in regulations, timing of approvals, the adoption of new regulations or the expansion of jurisdiction by these agencies and other organizations
could have an adverse impact on our business and results of operations.

Our ability to obtain rate adjustments to maintain reasonable rates of return depends upon regulatory action under applicable statutes and regulations, and
we cannot provide assurance that rate adjustments will be obtained or reasonable authorized rates of return on capital will be earned. Minnesota Power and
SWL&P,  from  time  to  time,  file  general  rate  cases  with,  or  otherwise  seek  cost  recovery  authorization  from,  federal  and  state  regulatory  authorities.  If
Minnesota Power and SWL&P do not receive an adequate amount of rate relief in general rate cases, including if rates are reduced, if increased rates are
not approved or recovered on a timely basis, if fuel adjustment clause recoveries or cost recovery for other items are not granted at the requested level, or
costs are otherwise unable to be recovered through rates, we may experience an adverse impact on our financial position, results of operations and cash
flows. We are unable to predict the impact on our business and results of operations from future legislation or regulatory activities of any of these agencies
or organizations.

Our regulated operations present certain environmental risks that could adversely affect our financial position and results of operations, including
effects of environmental laws and regulations, physical risks associated with climate change and initiatives designed to reduce the impact of GHG
emissions.

We are subject to extensive environmental laws and regulations affecting many aspects of our past, present and future operations, including air quality,
water quality and usage, waste management, reclamation, hazardous wastes, avian mortality and natural resources. These laws and regulations, or new laws
and  regulations  that  may  be  passed,  can  result  in  increased  capital  expenditures  and  increased  operating  and  other  costs  as  a  result  of  compliance,
remediation,  containment  and  monitoring  obligations,  particularly  with  regard  to  laws  relating  to  emissions,  coal  ash  and  water  discharge  at  generating
facilities.

These  laws  and  regulations  could  restrict  the  output  of  some  existing  facilities,  limit  the  use  of  some  fuels  in  the  production  of  electricity,  require  the
installation of additional pollution control equipment, require participation in environmental emission allowance trading, and lead to other environmental
considerations and costs, which could have an adverse impact on our business, operations and results of operations.

These  laws  and  regulations  generally  require  us  to  obtain  and  comply  with  a  wide  variety  of  environmental  licenses,  permits,  inspections  and  other
approvals.  Violations  of  these  laws  and  regulations  could  expose  us  to  regulatory  and  legal  proceedings,  disputes  with,  and  legal  challenges  by,
governmental authorities and private parties, as well as potential significant civil fines criminal penalties and other sanctions.

Existing environmental regulations may be revised and new environmental regulations may be adopted or become applicable to us. Revised or additional
regulations  which  result  in  increased  compliance  costs  or  additional  operating  restrictions,  particularly  if  those  costs  are  not  fully  recoverable  from
customers, could have an adverse effect on our results of operations.

There  is  significant  uncertainty  regarding  if  and  when  new  laws,  regulations  or  administrative  policies  will  be  adopted  to  reduce  or  limit  GHG  and  the
impact any such laws or regulations would have on us. In 2021, our operating coal-fired generating facilities consisted of the 355 MW Boswell Unit 3 and
the  468  MW  Boswell  Unit  4.  (See  Outlook  –  EnergyForward.)  Any  future  limits  on  GHG  emissions  at  the  federal  or  state  level,  or  action  taken  by
regulators, before these facilities are retired or become coal-free may require us to incur significant capital expenditures and increases in operating costs, or
could result in early closure of coal-fired generating facilities, stranded assets, an impairment of assets, denial of full recovery of decommissioning costs in
excess of amounts previously collected, or otherwise adversely affect our results of operations, particularly if resulting expenditures and costs are not fully
recoverable from customers.

Our  regulated  operations  may  be  adversely  impacted  by  the  physical  and  financial  risks  associated  with  climate  change.  See  Entity-wide  Risks  for
additional discussion of risks related to GHG and climate change.

We cannot predict the amount or timing of all future expenditures related to environmental matters because of uncertainty as to applicable regulations or
requirements.  There  is  also  uncertainty  in  quantifying  liabilities  under  environmental  laws  that  impose  joint  and  several  liability  on  all  potentially
responsible  parties.  Violations  of  certain  environmental  statutes,  rules  and  regulations  could  expose  ALLETE  to  third  party  disputes  and  potentially
significant monetary penalties, as well as other sanctions for non‑compliance.

The  operation  and  maintenance  of  our  regulated  electric  generation  and  transmission  facilities  are  subject  to  operational  risks  that  could
adversely affect our financial position, results of operations and cash flows.

The  operation  of  generating  facilities  involves  many  risks,  including  start-up  operational  risks,  breakdown  or  failure  of  facilities,  the  dependence  on  a
specific fuel source, inadequate fuel supply, availability of fuel transportation, and the impact of unusual or adverse weather conditions or other natural
events,  as  well  as  the  risk  of  performance  below  expected  levels  of  output  or  efficiency.  A  significant  portion  of  our  facilities  contain  older  generating
equipment, which, even if maintained in accordance with good engineering practices, may require significant capital expenditures to continue operating at
peak  efficiency.  Generation  and  transmission  facilities  and  equipment  are  also  likely  to  require  periodic  upgrades  and  improvements  due  to  changing
environmental  standards  and  technological  advances.  We  could  be  subject  to  costs  associated  with  any  unexpected  failure  to  produce  or  deliver  power,
including failure caused by breakdown, forced outage or limited availability of fuel or fuel transportation, as well as the repair of damage to facilities due to
breakdown,  storms,  natural  disasters,  wars,  sabotage,  terrorist  acts  and  other  catastrophic  events.  This  could  also  lead  to  requiring  additional  purchased
power to meet requirements of serving our retail load, which for Minnesota Power is subject to recovery under the fuel adjustment clause. Should these
costs be denied or are otherwise unable to be recovered, our financial position, results of operations and cash flows could be adversely impacted.

Our  ability  to  successfully  and  timely  complete  capital  repairs  or  improvements  to  existing  regulated  facilities  or  other  capital  projects  is
contingent upon many variables.

We expect to incur significant capital expenditures in making capital repairs or improvements to our existing electric generation and transmission facilities
and in the development and construction of new electric generation and transmission facilities. Should any such efforts be unsuccessful, not completed in a
timely manner or if there are increases in the costs for or limited availability of key materials, supplies, labor and services, we could be subject to additional
costs or impairments which could have an adverse impact on our financial position, results of operation and cash flows.

Our  regulated  electric  generating  operations  may  not  have  access  to  adequate  and  reliable  transmission  and  distribution  facilities  necessary  to
deliver electricity to our customers.

We depend on our own transmission and distribution facilities, as well as facilities owned by other utilities, to deliver the electricity produced and sold to
our customers, and to other energy suppliers. If transmission capacity is inadequate, our ability to sell and deliver electricity may be limited. We may have
to forgo sales or may have to buy more expensive wholesale electricity that is available in the capacity-constrained area. In addition, any infrastructure
failure that interrupts or impairs delivery of electricity to our customers could negatively impact the satisfaction of our customers, which could have an
adverse impact on our business and results of operations.

The price of electricity may be volatile and fuel may be volatile and availability may be limited.

Volatility in market prices for electricity and volatility and limited availability of fuel could adversely impact our financial position and results of operations
and may result from:

severe or unexpected weather conditions and natural disasters;
seasonality;
changes in electricity usage;
transmission or transportation constraints, inoperability or inefficiencies;
availability of competitively priced alternative energy sources;
changes in supply and demand for energy;
changes in power production capacity;
outages at our generating facilities or those of our competitors;
availability of fuel and transportation of fuel;
changes in production and storage levels of natural gas, lignite, coal, crude oil and refined products;

•
•
•
•
•
•
•
•
•
•
• wars, sabotage, terrorist acts or other catastrophic events; and
•

federal, state, local and foreign energy, environmental, or other regulation and legislation.

Volatility in market prices for our fuel and purchase power costs impacts our sales to retail, municipal and Other Power Suppliers. Fluctuations in our fuel
and  purchased  power  costs  related  to  our  retail  and  municipal  customers  are  passed  on  to  customers  through  the  fuel  adjustment  clause;  however,  our
results of operations and cash flows may be adversely impacted if increased fuel adjustment clause rates are not approved or recovered on a timely basis, if
cost recovery is not granted at the requested level, or costs are otherwise unable to be recovered through the fuel adjustment clause.

Wholesale  prices  for  electricity  have  also  declined  in  recent  years  primarily  due  to  low  natural  gas  prices,  the  extension  of  renewable  tax  credits  and
additional renewable generation commencing operations. If there are reductions in demand from current customers, we lose retail customers, or we lose
municipal  customers  that  do  not  renew  existing  contracts,  we  will  market  any  available  power  to  Other  Power  Suppliers  in  an  effort  to  mitigate  any
earnings impact. Sales to Other Power Suppliers are sold at market-based prices into the MISO market on a daily basis or through bilateral agreements of
various  durations.  Due  to  wholesale  prices  for  electricity  being  below  our  rates  for  retail  and  municipal  customers,  we  do  not  expect  that  our  power
marketing efforts would fully offset the reduction in earnings resulting from the lower demand from existing customers or the loss of customers. (See Item

Demand for energy may decrease.

Our results of operations are impacted by the demand for energy in our service territories, our municipal customers and other power suppliers. There could
be  lower  demand  for  energy  due  to  a  loss  of  customers  as  a  result  of  economic  conditions,  customers  constructing  or  installing  their  own  generation
facilities,  higher  costs  and  rates  charged  to  customers,  eligible  municipal  and  other  power  suppliers  choosing  an  alternative  energy  provider,  or  loss  of
service territory or franchises. Further, energy conservation and technological advances that increased energy efficiency may temporarily or permanently
reduce the demand for energy products. In addition, we are impacted by state and federal regulations requiring mandatory conservation measures, which
reduce  the  demand  for  energy  products.  Continuing  technology  improvements  and  regulatory  developments  may  make  customer  and  third  party-owned
generation  technologies  such  as  rooftop  solar  systems,  WTGs,  microturbines  and  battery  storage  systems  more  cost  effective  and  feasible  for  of  our
customers. If customers utilize their own generation, demand for energy from us would decline. There may not be future economic growth opportunities
that  would  enable  us  to  replace  the  lost  energy  demand  from  these  customers.  Therefore,  a  decrease  in  demand  for  energy  could  adversely  impact  our
financial position, results of operations and cash flows.

ALLETE Clean Energy / Corporate and Other Risks

The inability to successfully manage and grow ALLETE Clean Energy and our Corporate and Other businesses could adversely affect our results
of operations.

The  Company's  strategy  includes  adding  customers,  new  geographies,  and  growth  through  acquisitions  or  project  development  with  long-term  PSAs  in
place for the output or to be sold upon completion. This strategy depends, in part, on the Company’s ability to successfully identify and evaluate acquisition
or development opportunities and consummate acquisitions on acceptable terms. The Company may compete with other companies for these acquisition
and development opportunities, which may increase the Company’s cost of making acquisitions and the Company may be unsuccessful in pursuing these
acquisition opportunities. Other companies may be able to pay more for acquisitions and may be able to identify, evaluate, bid for and purchase a greater
number of assets than the Company’s financial or human resources permit. New laws and regulations promoting renewable energy generation may result in
increased competition. Our ALLETE Clean Energy business is experiencing return pressures from increased competition, and lower forward price curves,
as a growing amount of investment capital is being directed into wind generation opportunities. In addition, current and potential new project developments
can  be  negatively  affected  by  a  lower  ALLETE  stock  price,  which  may  result  in  such  projects  not  being  accretive,  or  otherwise  unable  to  satisfy  our
financial  objectives  criteria  to  proceed.  Additionally,  tax  law  changes  may  adversely  impact  the  economic  characteristics  of  potential  acquisitions  or
investments. Any reductions or modifications to, or the elimination of, governmental incentives or policies that support renewable energy or the imposition
of additional taxes or other assessments on renewable energy, could result in, among other items, the lack of a satisfactory market for the development or
financing  of  new  renewable  energy  projects  and  reduced  project  returns  on  future  projects.  If  the  Company  is  unable  to  execute  its  strategy  of  growth
through  acquisitions,  project  development  for  others,  or  the  addition  of  new  customers  and  geographies,  it  may  impede  our  long-term  objectives  and
business strategy.

Acquisitions are subject to uncertainties. If we are unable to successfully integrate and manage future acquisitions or strategic investments, this could have
an adverse impact on our results of operations. Our actual results may also differ from our expectations due to factors such as the ability to obtain timely
regulatory or governmental approvals, integration and operational issues and the ability to retain management and other key personnel.

The generation of electricity from wind and solar energy facilities depends heavily on suitable meteorological conditions.

Although  our  electric  generation  facilities  are  located  in  diverse  geographic  regions  to  reduce  the  potential  impact  that  may  be  caused  by  unfavorable
weather  in  a  particular  region,  suitable  meteorological  conditions  are  variable  and  difficult  to  predict.  If  wind  or  solar  conditions  are  unfavorable  or
meteorological  conditions  are  unsuitable,  electricity  generation  and  revenue  from  wind  and  solar  energy  facilities  may  be  substantially  below  our
expectations. The electricity produced, production tax credits received, and revenues generated by a wind or solar energy facility are highly dependent on
suitable wind conditions and associated weather conditions, which are variable and beyond our control. We base our decisions about which wind and solar
projects  to  build  or  acquire  as  well  as  our  electricity  generation  estimates,  in  part,  on  the  findings  of  long-term  wind  and  other  meteorological  studies
conducted on the project site and its region; however, the unpredictable nature of wind and solar conditions, weather and meteorological conditions can
result in material deviations from these studies and our expectations. Furthermore, components of our systems could be damaged by severe weather, such
as  hailstorms,  lightning  or  tornadoes.  In  addition,  replacement  and  spare  parts  for  key  components  may  be  difficult  or  costly  to  acquire  or  may  be
unavailable. Unfavorable wind and solar conditions, weather or changes to meteorological patterns could impair the effectiveness of our electric generation
facility assets, reduce their output beneath their rated capacity or require shutdown of key equipment, impeding operation of our wind energy facilities or
lead to an impairment of assets.

The construction, operation and maintenance of our electric generation facilities or investment in facilities are subject to operational risks that
could adversely affect our financial position, results of operations and cash flows.

The  construction  and  operation  of  generating  facilities  involves  many  risks,  including  the  performance  by  key  contracted  suppliers  and  maintenance
providers; increases in the costs for or limited availability of key materials, supplies, labor and services; start-up operations risks; breakdown or failure of
facilities;  curtailment  of  facilities  by  counterparties;  the  dependence  on  the  availability  of  wind  resources;  or  the  impact  of  unusual,  adverse  weather
conditions or other natural events, as well as the risk of performance below expected levels of output or efficiency. Some of our facilities contain older
generating equipment, which even if maintained in accordance with good engineering practices, may require significant capital expenditures to continue
operating at peak efficiency. We could be subject to costs associated with any unexpected failure to produce and deliver power, including failure caused by
breakdown or forced outage, as well as the repair of damage to facilities due to storms, natural disasters, wars, sabotage, terrorist acts and other catastrophic
events.

The price of electricity may be volatile, which may impact results of operations at ALLETE Clean Energy wind energy facilities under contracts
with customer and industrial (C&I) customers.

Unusual, adverse weather conditions or other natural events can cause volatility in market prices for electricity and adversely affect our financial position,
results of operations and cash flows. ALLETE Clean Energy’s power sales agreements with its three C&I customers at its Diamond Spring wind energy
facility  are  contracts  for  differences  where  power  is  delivered  to  the  market,  and  a  fixed  price  is  paid  by  the  customers  to  ALLETE  Clean  Energy,  and
differences between the market price and the fixed price are paid to or received from the customers. One of these power sales agreements settles with the
customer based on day-ahead electricity prices, while deliveries to the market are settled based on real-time electricity prices. This settlement provision can
and has resulted in an adverse impact to the Company when market prices are extremely volatile as happened in February 2021 during an extreme winter
weather event in the southwest United States. This winter weather event caused extreme volatility, with large differences in the day-ahead and real-time
market  prices;  the  settlement  provision  resulted  in  an  approximately  $5  million  after-tax  negative  impact  related  to  the  Diamond  Spring  wind  energy
facility in 2021.

As contracts with counterparties expire, we may not be able to replace them with agreements on similar terms or divest the related assets at a
profit.

ALLETE Clean Energy is party to PSAs which expire in various years between 2022 and 2039. These PSA expirations are prior to the end of the estimated
useful lives of the respective wind energy facilities. If, for any reason, ALLETE Clean Energy is unable to enter into new agreements with existing or new
counterparties on similar terms once the current agreements expire, sell energy in the wholesale market resulting in similar revenue, or enter into a contract
to sell the facility at a profit, our financial position, results of operations and cash flows could be adversely affected, which includes potential impairment of
property, plant and equipment.

Counterparties to turbine and other generation supply, service and maintenance, or power sale agreements may not fulfill their obligations.

Our businesses are party to turbine and other generation supply agreements, service and maintenance agreements, and PSAs under various durations with a
limited number of creditworthy counterparties. If, for any reason, any of the counterparties under these agreements do not fulfill their related contractual
obligations, and we are unable to mitigate non-performance by a key supplier or maintenance provider or remarket PSA energy resulting in similar revenue,
our financial position, results of operations and cash flows could be adversely affected.

BNI Energy may be adversely impacted by its exposure to customer concentration, and environmental laws and regulations.

BNI  Energy  sells  lignite  coal  to  two  electric  generating  cooperatives,  Minnkota  Power  and  Square  Butte,  and  could  be  adversely  impacted  if  these
customers were unable or unwilling to fulfill their related contractual obligations, or change the way in which they operate their generating facilities. In
addition, BNI Energy and its customers may be adversely impacted by existing or new environmental laws and regulations which could have an adverse
effect on our financial position, results of operations and cash flows. In addition, insurance companies have decreased the available coverage for policy
holders in the mining industry, impacting the availability of coverage, and leading to higher deductibles and premiums.

Real estate market conditions where our legacy Florida real estate investment is located may deteriorate.

The Company’s strategy related to the real estate assets of ALLETE Properties incorporates the possibility of a bulk sale of its entire portfolio, in addition
to sales over time, however, adverse market conditions could impact the timing of land sales, which could result in little to no sales, while still incurring
operating  expenses  such  as  community  development  district  assessments  and  property  taxes,  resulting  in  net  operating  losses  at  ALLETE  Properties.
Furthermore, weak market conditions could put the properties at risk for an impairment charge. An impairment charge would result in a non-cash charge to
earnings that could have an adverse effect on our results of operations.

Entity-wide Risks

We could be materially adversely affected by health epidemics, pandemics and other outbreaks, such as the ongoing COVID-19 pandemic.

The ongoing COVID-19 pandemic has resulted in widespread impacts on the global economy and on our employees, customers, contractors, and suppliers.
There is considerable uncertainty regarding the length of time for which COVID-19 will continue, if new variants will emerge or the extent and duration of
measures  to  try  to  contain  the  virus.  We  are  responding  to  the  COVID-19  pandemic  by  taking  steps  to  mitigate  the  potential  risks  to  us  posed  by  its
transmission  and  have  implemented  company-wide  business  continuity  plans  in  response  to  the  pandemic.  These  plans  guide  our  emergency  response,
business continuity, and the precautionary measures we are taking on behalf of employees and the public. We have taken additional precautions for our
employees who work in the field and for employees who continue to work in our facilities, and we have implemented work from home policies where
appropriate.  We  continue  to  implement  physical  and  cyber-security  measures  to  ensure  that  our  systems  remain  functional  in  order  to  both  serve  our
operational needs with a remote workforce and keep them running to ensure uninterrupted service to our customers.

The ongoing COVID-19 pandemic and related federal and state government responses has led to a disruption of economic activity, and could result in an
extended disruption of economic activity. Further disruption of economic activity or an extended disruption of economic activity may lead to additional
adverse  impacts  on  our  taconite,  paper,  pulp  and  secondary  wood  products,  and  pipeline  customers’  operations  including  reduced  production  or  the
temporary idling or indefinite shutdown of facilities, which would result in lower sales and revenue from these customers.

The Company is monitoring the capital markets and has access to liquidity to enable us to operate our businesses and fund capital projects; however, a
disruption in capital markets could lead to increased borrowing costs or adversely impact our ability to access capital markets or other financing sources. If
we  are  not  able  to  access  capital  on  acceptable  terms  in  sufficient  amounts  and  when  needed,  or  at  all,  the  ability  to  maintain  our  businesses  or  to
implement our business plans would be adversely affected. In addition, the performance of capital markets impacts the values of the assets that are held in
trust to satisfy future obligations under our pension and other postretirement benefit plans. A decline in the market value of these assets would increase the
funding requirements under our benefit plans and future costs recognized for the benefit plans if the asset market values do not recover. The Company is
also monitoring supply chains for key materials, supplies, labor and services for our operations and large capital projects. The pandemic could result in a
disruption to our supply chains which could adversely impact our operations and capital projects. There has been some impact on our supply chains as to
the availability of and price for materials, supplies and services to date. In addition, disruptions in our supply chains or a lack of available financing could
jeopardize our ability to complete certain capital projects in time to qualify them for production tax credits.

We will continue to monitor developments affecting our workforce, operations and customers, and we will take additional precautions that we determine
are  necessary  in  order  to  mitigate  the  impacts  of  the  COVID-19  pandemic.  Despite  our  efforts  to  manage  these  impacts  to  the  Company,  their  ultimate
impact also depends on factors beyond our control, including the duration and severity of this pandemic as well as governmental and third-party actions
taken to contain its spread and mitigate its public health effects. As a result, we cannot predict the ultimate impact of the COVID-19 pandemic and whether
it will have a material impact on our liquidity, financial position, results of operations and cash flows.

We rely on access to financing sources and capital markets. If we do not have access to capital on acceptable terms or are unable to obtain capital
when needed, our ability to execute our business plans, make capital expenditures or pursue other strategic actions that we may otherwise rely on
for future growth would be adversely affected.

We rely on access to financing sources and the capital markets, on acceptable terms and at reasonable costs, as sources of liquidity for capital requirements
not satisfied by our cash flows from operations. Market disruptions or a downgrade of our credit ratings may increase the cost of borrowing or adversely
affect our ability to access and finance in the capital markets or to access other financing sources such as tax equity financing. Such disruptions or causes of
a downgrade could include but are not limited to: weakening of the Company’s cash flow metrics; a loss of, or a reduction in sales to, our taconite, paper
and pipeline customers if we are unable to offset the related lost margins; weaker operating performance; adverse regulatory outcomes; disproportionate
increase in the contribution to net income from ALLETE Clean Energy and our Corporate and Other businesses as compared to that from our Regulated
Operations; deteriorating economic or capital market conditions; or volatility in commodity prices.  

If  we  are  not  able  to  access  capital  on  acceptable  terms  in  sufficient  amounts  and  when  needed,  or  at  all,  the  ability  to  maintain  our  businesses  or  to
implement our business plans would be adversely affected.

A  deterioration  in  general  economic  conditions,  an  inflationary  environment  or  supply  chain  disruptions  may  have  adverse  impacts  on  our
financial position, results of operations and cash flows.

If economic conditions deteriorate, we experience an inflationary environment or supply chains are disrupted on a national or regional level, it may have a
negative impact on the Company’s financial position, results of operations and cash flows as well as on our customers. This impact may include volatility
and  unpredictability  in  the  demand  for  the  products  and  services  offered  by  our  businesses,  the  loss  of  existing  customers,  tempered  growth  strategies,
customer production cutbacks, customer bankruptcies and increases in costs for or limited availability of key materials, supplies, labor and services for our
operations  and  capital  projects.  An  uncertain  economy  could  also  adversely  affect  expenses  including  pension  costs,  interest  costs,  and  uncollectible
accounts, or lead to reductions in the value of certain real estate and other investments.

Our businesses, investments and customers are subject to, and affected by, extensive state and federal legislation and regulation. If it was determined that
our businesses failed to comply with applicable laws and regulations, we could become subject to fines or penalties or be required to implement additional
compliance measures or actions, the cost of which could be material. Adoption of new laws, rules, regulations, principles, or practices by federal and state
agencies, or changes to or a failure to comply with current laws, rules, regulations, principles, or practices and their interpretations, could have an adverse
effect on our financial position, results of operations and cash flows.

The  inability  to  attract  and  retain  a  qualified  workforce  including,  but  not  limited  to,  executive  officers,  key  employees  and  employees  with
specialized skills, could have an adverse effect on our operations.

The  success  of  our  business  heavily  depends  on  the  leadership  of  our  executive  officers  and  key  employees  to  implement  our  business  strategy.  The
inability  to  maintain  a  qualified  workforce  including,  but  not  limited  to,  executive  officers,  key  employees  and  employees  with  specialized  skills,  may
negatively affect our ability to service our existing or new customers, or successfully manage our business or achieve our business objectives. Personnel
costs may increase due to competitive pressures, inflation or terms of collective bargaining agreements with union employees.

Market  performance  and  other  changes  could  decrease  the  value  of  pension  and  other  postretirement  benefit  plan  assets,  which  may  result  in
significant additional funding requirements and increased annual expenses.

The  performance  of  the  capital  markets  impacts  the  values  of  the  assets  that  are  held  in  trust  to  satisfy  future  obligations  under  our  pension  and  other
postretirement  benefit  plans.  We  have  significant  obligations  to  these  plans  and  the  trusts  hold  significant  assets.  These  assets  are  subject  to  market
fluctuations and will yield uncertain returns, which may fall below our projected rates of return. A decline in the market value of the pension and other
postretirement benefit plan assets would increase the funding requirements under our benefit plans if asset returns do not recover. Additionally, our pension
and  other  postretirement  benefit  plan  liabilities  are  sensitive  to  changes  in  interest  rates.  As  interest  rates  decrease,  the  liabilities  increase,  potentially
increasing benefit expense and funding requirements. Our pension and other postretirement benefit plan costs are generally recoverable in our electric rates
as allowed by our regulators or through our cost-plus fixed fee coal supply agreements at BNI Energy; however, there is no certainty that regulators will
continue to allow recovery of these rising costs in the future.

We are exposed to significant reputational risk.

The Company could suffer negative impacts to its reputation as a result of operational incidents, violations of corporate compliance policies, regulatory
violations, or other events which may result in negative customer perception and increased regulatory oversight, each of which could have an adverse effect
on our financial position, results of operations and cash flows.

We are subject to physical and financial risks associated with climate change and other catastrophic events, such as natural disasters and acts of
war.

Catastrophic events at or near Company facilities and equipment on which the Company depends upon or that otherwise impact the Company such as fires,
wildfires, including the impact to Company facilities and operations or potential liability if caused by Company equipment, earthquakes, explosions, and
floods, severe weather, such as ice storms, hailstorms, or tornadoes or similar occurrences, as well as acts of war, could adversely affect the Company’s
facilities, operations, financial position, results of operations and cash flows. Although the Company has contingency plans and employs crisis management
to  respond  and  recover  operations  in  the  event  of  a  severe  disruption  resulting  from  a  catastrophic  event,  these  measures  may  not  be  successful.
Furthermore, despite these measures, if a catastrophic event were to occur, our financial position, results of operations and cash flows could be adversely
affected.

Item 1A. Risk Factors (Continued)
Entity-wide Risks (Continued)

The scientific community generally accepts that emissions of GHG are linked to global climate change. Physical risks of climate change, such as more
frequent,  longer  duration  or  more  extreme  weather  events,  changes  in  temperature  and  precipitation  patterns,  changes  to  ground  and  surface  water
availability, and other related phenomena, could affect some, or all, of our operations. Severe weather or other natural disasters could be destructive, which
could result in increased costs or limit the availability of key materials, supplies, labor and services. An extreme weather event can also directly affect our
capital assets, causing disruption in service to customers due to facility outages, downed wires and poles or damage to other operating equipment.

Climate-related risks that could adversely affect our financial position and results of operations include effects of environmental- or economic-based laws,
regulations, incentives or initiatives designed to reduce the quantity or impact of GHG emissions. This includes the risk of laws or regulations that create
mandates that do not allow for a transition that protects the safety, reliability or affordability of energy for our customers, are implemented before cost-
effective technology is developed and regulatory policy is established, or require the electric sector to decarbonize faster than other sectors and ahead of our
current  goal  to  deliver  100  percent  carbon-free  energy  to  customers  by  2050.  Additionally,  restrictions  on  land  use,  wildlife  impacts,  and  other
environmental regulations could affect the siting, construction and operation of new or existing generation and transmission facilities needed to transition to
lower-carbon generation sources.

These all have the potential to adversely affect our business and operations.

We are vulnerable to acts of terrorism or cybersecurity attacks.

Our  operations  may  be  targets  of  terrorist  activities  or  cybersecurity  attacks,  which  could  disrupt  our  ability  to  provide  utility  service  at  our  regulated
utilities, develop or operate our renewable energy projects at ALLETE Clean Energy, or operate our other businesses. The impacts may also impair the
fulfillment  of  critical  business  functions,  negatively  impact  our  reputation,  subject  us  to  litigation  or  increased  regulation,  or  compromise  sensitive,
confidential and other data.

There have been cybersecurity attacks on U.S. energy infrastructure in the past and there may be such attacks in the future. Our generation, transmission
and  distribution  facilities,  information  technology  systems  and  other  infrastructure  facilities  and  systems  could  be  direct  targets  of,  or  otherwise  be
materially adversely affected by such activities. Hacking, computer viruses, terrorism, theft and sabotage could impact our systems and facilities, or those
of third parties on which we rely, which may disrupt our operations.

Our  businesses  require  the  continued  operation  of  sophisticated  custom-developed,  purchased,  and  leased  information  technology  systems  and  network
infrastructure  as  well  as  the  collection  and  retention  of  personally  identifiable  information  of  our  customers,  shareholders  and  employees.  Although  we
maintain security measures designed to prevent cybersecurity incidents and protect our information technology and control systems, network infrastructure
and other assets, our technology systems, or those of third parties on which we rely, may be vulnerable to disability, failures or unauthorized access due to
hacking, viruses, acts of war or terrorism as well as other causes. If those technology systems fail or are breached and not recovered in a timely manner, we
may be unable to perform critical business functions including effectively maintaining certain internal controls over financial reporting, our reputation may
be negatively impacted, we may become subject to litigation or increased regulation, and sensitive, confidential and other data could be compromised. If
our business were impacted by terrorist activities or cybersecurity attacks, such impacts could have an adverse effect on our financial position, results of
operations and cash flows.

We maintain insurance against some, but not all, of the risks and uncertainties we face.

We maintain insurance against some, but not all, of the risks and uncertainties we face. The occurrence of these risks and uncertainties, if not fully covered
by insurance, could have a material effect on our financial position, results of operations and cash flows.

Item 1A. Risk Factors (Continued)
Entity-wide Risks (Continued)

Government  challenges  to  our  tax  positions,  as  well  as  tax  law  changes  and  the  inherent  difficulty  in  quantifying  potential  tax  effects  of  our
operations and business decisions, could adversely affect our results of operations and liquidity.

We are required to make judgments regarding the potential tax effects of various financial transactions and our ongoing operations in order to estimate our
obligations to taxing authorities. The obligations, which include income taxes and taxes other than income taxes, involve complex matters that ultimately
could be litigated. We also estimate our ability to use tax benefits, including those in the form of carryforwards and tax credits that are recorded as deferred
tax assets on our Consolidated Balance Sheet. A disallowance of some or all of these tax benefits could have an adverse impact on our financial position,
results of operations and cash flows.

We are currently utilizing, and plan to utilize in the future, our carryforwards and tax credits to reduce our income tax obligations. If we cannot generate
enough taxable income in the future to utilize all of our carryforwards and tax credits before they expire, we may incur adverse charges to earnings.

If federal or state tax authorities deny any deductions or tax credits, negatively change existing tax laws or policies, or fail to extend or renew policies
beneficial to the Company, such as those for renewable energy production tax credits, our financial position, results of operations and cash flows may be
adversely impacted.

results of operations or cash flows.

Minnesota Power has been named in a lawsuit where a contractor performing work at one of its facilities experienced an injury and subsequently filed a
lawsuit seeking compensatory damages. Litigation related to this injury is ongoing. At this time, a loss is considered reasonably possible; however, we do
not deem it probable, and we are unable to estimate a loss or range of loss related to the litigation at this time.

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Our  common  stock  is  listed  on  the  NYSE  under  the  symbol  ALE.  We  have  paid  dividends,  without  interruption,  on  our  common  stock  since  1948.  A
quarterly dividend of $0.65 per share on our common stock is payable on March 1, 2022, to the shareholders of record on February 15, 2022. The timing
and amount of future dividends will depend upon earnings, cash requirements, the financial condition of the Company, applicable government regulations
and  other  factors  deemed  relevant  by  the  ALLETE  Board  of  Directors.  As  of  February  1,  2022,  there  were  approximately  20,000  common  stock
shareholders of record.

Performance Graph.

The following graph compares ALLETE’s cumulative Total Shareholder Return on its common stock with the cumulative return of the S&P 500 Index and
the Philadelphia Utility Index. The S&P 500 Index is a capitalization-weighted index of 500 stocks designed to measure performance of the broad domestic
economy through changes in the aggregate market value of 500 stocks representing all major industries. Because this composite index has a broad industry
base,  its  performance  may  not  closely  track  that  of  a  composite  index  comprised  solely  of  electric  utilities.  The  Philadelphia  Utility  Index  is  a
capitalization-weighted index of 20 utility companies involved in the generation of electricity.

The calculations assume a $100 investment on December 31, 2016, and reinvestment of dividends.

Overview

Basis of Presentation. We present three reportable segments: Regulated Operations, ALLETE Clean Energy and U.S. Water Services. Our segments were
determined  in  accordance  with  the  guidance  on  segment  reporting.  We  measure  performance  of  our  operations  through  budgeting  and  monitoring  of
contributions to consolidated net income by each business segment.

Regulated Operations  includes  our  regulated  utilities,  Minnesota  Power  and  SWL&P,  as  well  as  our  investment  in  ATC,  a  Wisconsin-based  regulated
utility  that  owns  and  maintains  electric  transmission  assets  in  portions  of  Wisconsin,  Michigan,  Minnesota  and  Illinois.  Minnesota  Power  provides
regulated  utility  electric  service  in  northeastern  Minnesota  to  approximately  150,000  retail  customers.  Minnesota  Power  also  has  15  non-affiliated
municipal  customers  in  Minnesota.  SWL&P  is  a  Wisconsin  utility  and  a  wholesale  customer  of  Minnesota  Power.  SWL&P  provides  regulated  utility
electric,  natural  gas  and  water  service  in  northwestern  Wisconsin  to  approximately  15,000  electric  customers,  13,000  natural  gas  customers  and
10,000  water  customers.  Our  regulated  utility  operations  include  retail  and  wholesale  activities  under  the  jurisdiction  of  state  and  federal  regulatory
authorities. (See Note 4. Regulatory Matters.)

ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects. ALLETE Clean Energy currently owns and
operates,  in  seven  states,  more  than  1,300  MW  of  nameplate  capacity  wind  energy  generation  that  is  contracted  under  PSAs  of  various  durations.  In
addition, ALLETE Clean Energy currently has approximately 200 MW of wind energy facilities under contract to be sold to others. ALLETE Clean Energy
also engages in the development of wind energy facilities to operate under long-term PSAs or for sale to others upon completion.

U.S.  Water  Services  provided  integrated  water  management  for  industry  by  combining  chemical,  equipment,  engineering  and  service  for  customized
solutions to reduce water and energy usage, and improve efficiency. In March 2019, the Company sold U.S. Water Services to a subsidiary of Kurita Water
Industries Ltd.

Corporate  and  Other is  comprised  of  BNI  Energy,  our  coal  mining  operations  in  North  Dakota;  our  investment  in  Nobles  2,  an  entity  that  owns  and
operates a 250 MW wind energy facility in southwestern Minnesota; South Shore Energy, our non-rate regulated, Wisconsin subsidiary developing NTEC,
an approximately 600 MW proposed combined-cycle natural gas-fired generating facility; ALLETE Properties, our legacy Florida real estate investment;
other  business  development  and  corporate  expenditures;  unallocated  interest  expense;  a  small  amount  of  non-rate  base  generation;  approximately
4,000 acres of land in Minnesota; and earnings on cash and investments.

Overview (Continued)

ALLETE  is  incorporated  under  the  laws  of  Minnesota.  Our  corporate  headquarters  are  in  Duluth,  Minnesota.  Statistical  information  is  presented  as  of
December  31,  2021,  unless  otherwise  indicated.  All  subsidiaries  are  wholly-owned  unless  otherwise  specifically  indicated.  References  in  this  report  to
“we,” “us” and “our” are to ALLETE and its subsidiaries, collectively.

2021 Financial Overview

The following net income discussion summarizes a comparison of the year ended December 31, 2021 to the year ended December 31, 2020. The trends and
results  for  the  year  ended  December  31,  2021  may  not  be  indicative  of  future  results  due  to  uncertainty  regarding  the  COVID-19  pandemic.  (See
Overview.)

Net income attributable to ALLETE in 2021 was $169.2 million, or $3.23 per diluted share, compared to $174.2 million, or $3.35 per diluted share, in
2020.  Net  income  in  2021  included  South  Shore  Energy’s  sale  of  a  portion  of  its  interest  in  NTEC  to  Basin  Electric  Cooperative.  The  closing  of  the
transaction between South Shore Energy and Basin resulted in the recognition of an approximately $8.5 million after-tax gain, or $0.16 per share, related to
prior development costs and risks incurred. Net income in 2021 also included an approximately $5 million after-tax, or $0.10 per share, negative impact
related to ALLETE Clean Energy’s Diamond Spring wind energy facility due to an extreme winter storm event in the southwest United States in February
2021. This winter storm event caused volatility in power prices in the regional power market resulting in losses being incurred under one of the facility’s
power sales agreements during portions of the winter storm event. Additionally, net income in 2021 included a $3.6 million after-tax, or $0.07 per share,
charge  resulting  from  the  MPUC’s  decision  to  order  refunds  in  Minnesota  Power’s  fuel  adjustment  clause  filing  covering  the  period  July  2018  through
December 2019. Net income in 2020 included margins of $10.2 million after-tax, or $0.20 per share, in Regulated Operations for sales under a 100 MW
PSA which expired in April 2020. Net income in 2020 also included reserves for interim rates of $8.3 million after-tax, or $0.16 per share, for the refund of
interim rates collected between January 1, 2020, and April 30, 2020. Earnings per share dilution in 2021 was $0.03 due to additional shares of common
stock outstanding as of December 31, 2021.

Regulated Operations net income attributable to ALLETE was $129.1 million in 2021, compared to $136.3 million in 2020. Net income at Minnesota
Power was lower than 2020 primarily due to: lower margins from Other Power Suppliers resulting primarily from the expiration of a PSA; higher operating
and  maintenance,  property  tax  and  depreciation  expenses;  and  a  reserve  for  refunds  resulting  from  the  MPUC’s  decision  to  order  refunds  in  Minnesota
Power’s fuel adjustment clause filing covering the period July 2018 through December 2019. These negative impacts were partially offset by increased
earnings related to the GNTL; and higher kWh sales to retail and municipal customers. Net income in 2020 also included reserves for interim rates of $8.3
million  after-tax  for  the  refund  of  interim  rates  collected  between  January  1,  2020,  and  April  30,  2020.  Net  income  at  SWL&P  was  lower  than  2020
primarily due to higher operating expenses. Our after-tax equity earnings in ATC were lower compared to 2020 primarily due to period over period changes
in ATC’s estimate of a refund liability related to the FERC decision on MISO return on equity complaints in 2020.

ALLETE Clean Energy net income attributable to ALLETE was $26.3 million in 2021 compared to $29.9 million in 2020. Net income in 2021 included
an approximately $5 million after-tax negative impact related to ALLETE Clean Energy’s Diamond Spring wind energy facility due to an extreme winter
storm event in the southwest United States in February 2021 as well as lower wind resources at other wind energy facilities. These negative impacts were
partially offset by expense management efforts.

Corporate and Other net income attributable to ALLETE was $13.8 million in 2021 compared to $8.0 million in 2020. Net income in 2021 included
South Shore Energy’s sale of a portion of its interest in NTEC to Basin Electric Cooperative which resulted in the recognition of an approximately $8.5
million after-tax gain related to prior development costs and risks incurred, higher earnings from our investment in Nobles 2 which commenced operations
in December 2020 and higher land sales at ALLETE Properties. These increases were partially offset by higher expenses.

Operating  Revenue  –  Utility  increased  $240.6  million  from  2020  primarily  due  to  higher  fuel  adjustment  clause  recoveries,  higher  kWh  sales,
increased  transmission-related  revenue  related  to  the  GNTL,  higher  cost  recovery  rider  revenue  and  higher  FERC  formula-based  rates.  Revenue  in
2020 also included reserves for the refund of interim rates collected between January 1, 2020, and April 30, 2020.

Fuel adjustment clause revenue increased $121.3 million due to higher fuel and purchased power costs attributable to retail and municipal customers.
(See Fuel, Purchased Power and Gas – Utility.) These increases were partially offset by a $5 million charge resulting from the MPUC’s decision to
order  refunds  in  Minnesota  Power’s  fuel  adjustment  clause  filing  covering  the  period  July  2018  through  December  2019.  (See  Note  4.  Regulatory
Matters.)

Revenue  from  kWh  sales  increased  $67.6  million  from  2020  primarily  due  to  higher  sales  to  commercial  and  industrial  customers  as  well  as  other
power suppliers. These increases were partially offset by lower revenue related to the expiration of a 100 MW PSA in April 2020. Sales to commercial
and  industrial  customers  increased  primarily  due  to  improving  business  conditions  related  to  the  COVID-19  pandemic  and  its  impact  on  customer
operations. Many commercial and industrial customers operated at reduced levels or were temporarily closed or idled during 2020 as a result of the
COVID-19  pandemic  and  related  governmental  responses  while  business  conditions  improved  in  2021.  These  higher  sales  to  commercial  and
industrial  customers  were  partially  offset  by  lower  sales  to  and  demand  revenue  from  Verso  Corporation  which  indefinitely  idled  its  paper  mill  in
Duluth,  Minnesota  in  2020.  (See  Outlook  –  Regulated  Operations  –  Industrial  Customers  and  Prospective  Additional  Load.)  Sales  to  other  power
suppliers, which are sold at market-based prices into the MISO market on a daily basis or through PSAs of various durations, increased primarily due
to additional kWh sales made to mitigate the uncertainty of customers’ energy needs and potential load loss due to the COVID-19 pandemic.

2021 Compared to 2020 (Continued)
Regulated Operations (Continued)

Revenue from electric sales to taconite customers accounted for 33 percent of regulated operating revenue in 2021 (30 percent in 2020). Revenue from
electric sales to paper, pulp and secondary wood product customers accounted for 5 percent of regulated operating revenue in 2021 (5 percent in 2020).
Revenue from electric sales to pipelines and other industrial customers accounted for 9 percent of regulated operating revenue in 2021 (9 percent in
2020).

Transmission-related revenue increased $17.7 million primarily due to recovery of GNTL expenses resulting from the GNTL being placed into service
in June 2020.

Revenue in 2020 included reserves of $11.7 million for the refund of interim rates collected between January 1, 2020, and April 30, 2020. (See Note 2.
Regulatory Matters.)

Cost recovery rider revenue increased $9.0 million primarily due to fewer production tax credits recognized by Minnesota Power. If production tax
credits  are  recognized  at  a  level  below  those  assumed  in  Minnesota  Power’s  base  rates,  an  increase  in  cost  recovery  rider  revenue  is  recognized  to
offset the impact of lower production tax credits on income tax expense.

Revenue from wholesale customers under FERC formula-based rates increased $5.2 million primarily due to higher rates.

Operating Expenses increased $241.2 million, or 29 percent, from 2020.

Fuel, Purchased Power and Gas – Utility expense increased $203.8 million, or 57 percent, from 2020 primarily due to higher purchased power prices,
kWh sales and fuel costs. Fuel and purchased power expense related to our retail and municipal customers is recovered through the fuel adjustment
clause.

Transmission Services – Utility expense increased $8.3 million, or 12 percent, from 2020 primarily due to higher MISO-related expense.

Operating  and  Maintenance  expense  increased  $15.1  million,  or  8  percent,  from  2020  primarily  due  to  an  increase  in  contract  and  professional
services  and  materials  purchased  for  generation  facilities  and  higher  vegetation  management  expenses.  In  addition,  2021  included  higher  labor  and
benefit expenses as compared to 2020.

Depreciation and Amortization expense increased $3.8 million, or 2 percent, from 2020 primarily due to additional property, plant and equipment in
service resulting from the GNTL being placed into service in June 2020.

Taxes  Other  than  Income  Taxes  increased  $10.2  million,  or  20  percent,  from  2020  primarily  due  to  higher  property  tax  expense  resulting  from  the
GNTL being placed into service in June 2020 as well as higher estimated taxable market values.

Other  Income  decreased  $4.0  million  from  2020  primarily  due  to  lower  pension  and  other  postretirement  plan  non-service  credits.  (See  Note  1.
Operations and Significant Accounting Policies.)

Income Tax Benefit  decreased  $2.8  million  from  2020  primarily  due  to  fewer  production  tax  credits  in  2021  compared  to  2020,  partially  offset  by
lower pre-tax income.

Cost of Sales increased $3.0 million from 2020 due to a reserve for an anticipated loss on sale of ALLETE Clean Energy’s project to repower and sell
its Northern Wind project. (See Outlook – ALLETE Clean Energy.)

Operating and Maintenance expense increased $4.1 million, or 11 percent, from 2020 primarily due to operating and maintenance expenses related to
the South Peak and Diamond Spring wind energy facilities as well as expense related to the Caddo wind energy facility which commenced operations
in December 2021. These increases were offset by expense management efforts.

Depreciation and Amortization expense increased $11.3 million, or 30 percent, from 2020 primarily due to additional property, plant and equipment in
service related to the South Peak and Diamond Spring wind energy facilities.

Taxes Other Than Income Taxes increased $3.8 million from 2020 primarily due to higher property tax expense related to the Diamond Spring wind
energy facility.

Income Tax Benefit decreased $2.5 million from 2020 primarily due to less production tax credits generated in 2021.

2021 Compared to 2020 (Continued)
ALLETE Clean Energy (Continued)

Net  Loss  Attributable  to  Non-Controlling  Interest  increased  $13.0  million  from  2020  primarily  due  to  net  losses  attributable  to  non-controlling
interest for the Diamond Spring wind energy facility.

Corporate and Other

Operating Revenue increased $2.2 million, or 2 percent, from 2020 primarily due to higher land sales at ALLETE Properties in 2021, partially offset
by  lower  revenue  at  BNI  Energy,  which  operates  under  cost-plus  fixed  fee  contracts,  as  a  result  of  lower  expenses  and  fewer  tons  sold  in  2021
compared to 2020.

Net Income Attributable to ALLETE was $13.8 million in 2021 compared to $8.0 million in 2020. Net income in 2021 included South Shore Energy’s
sale of a portion of its interest in NTEC to Basin Electric Cooperative which resulted in the recognition of an approximately $8.5 million after-tax gain
related  to  prior  development  costs  and  risks  incurred,  higher  earnings  from  our  investment  in  Nobles  2  which  commenced  operations  in  December
2020  and  higher  land  sales  at  ALLETE  Properties.  These  increases  were  partially  offset  by  higher  expenses.  Net  income  at  BNI  Energy  was  $7.5
million in 2021 compared to net income of $7.3 million in 2020. Net income at ALLETE Properties was $1.9 million in 2021 compared to net income
of $0.4 million in 2020.

Income Taxes – Consolidated

For the year ended December 31, 2021, the effective tax rate was a benefit of 24.3 percent (benefit of 32.4 percent for the year ended December 31,
2020). The effective tax rate for 2021 was a lower benefit primarily due to fewer production tax credits generated in 2021. (See Note 10. Income Tax
Expense.)

2020 Compared to 2019
The comparison of the results of operations for the years ended December 31, 2020 and 2019 is included in Management's Discussion in the Annual Report
on Form 10-K for the year ended December 31, 2020.

Critical Accounting Policies

The preparation of financial statements and related disclosures in conformity with GAAP requires management to make various estimates and assumptions
that affect amounts reported in the Consolidated Financial Statements. These estimates and assumptions may be revised, which may have a material effect
on  the  Consolidated  Financial  Statements.  Actual  results  may  differ  from  these  estimates  and  assumptions.  These  policies  are  discussed  with  the  Audit
Committee of our Board of Directors on a regular basis. We believe the following policies are most critical to our business and the understanding of our
results of operations.

Regulatory Accounting. Our regulated utility operations are subject to accounting standards for the effects of certain types of regulation. These standards
require us to reflect the effect of regulatory decisions in our financial statements. Regulatory assets represent incurred costs that have been deferred as they
are probable for recovery in customer rates. Regulatory liabilities represent obligations to make refunds to customers and amounts collected in rates for
which  the  related  costs  have  not  yet  been  incurred.  The  Company  assesses  quarterly  whether  regulatory  assets  and  liabilities  meet  the  criteria  for
probability of future recovery or deferral. This assessment considers factors such as, but not limited to, changes in the regulatory environment and recent
rate orders to other regulated entities under the same jurisdiction. If future recovery or refund of costs becomes no longer probable, the assets and liabilities
would be recognized in current period net income or other comprehensive income. (See Note 4. Regulatory Matters.)

ALLETE, Inc. 2021 Form 10-K

Critical Accounting Policies (Continued)

Pension  and  Postretirement  Health  and  Life  Actuarial  Assumptions.  We  account  for  our  pension  and  other  postretirement  benefit  obligations  in
accordance with the accounting standards for defined benefit pension and other postretirement plans. These standards require the use of several important
assumptions, including the expected long-term rate of return on plan assets, the discount rate and mortality assumptions, among others, in determining our
obligations and the annual cost of our pension and other postretirement benefits. In establishing the expected long-term rate of return on plan assets, we
determine the long-term historical performance of each asset class and adjust these for current economic conditions while utilizing the target allocation of
our  plan  assets  to  forecast  the  expected  long-term  rate  of  return.  Our  pension  asset  allocation  as  of  December  31,  2021,  was  approximately  49  percent
equity  securities,  48  percent  fixed  income  and  3  percent  real  estate.  Our  postretirement  health  and  life  asset  allocation  as  of  December  31,  2021,  was
approximately 70 percent equity securities, 29 percent fixed income and 1 percent private equity. Equity securities consist of a mix of market capitalization
sizes  with  domestic  and  international  securities.  In  2021,  we  used  weighted  average  expected  long-term  rates  of  return  of  6.50  percent  in  our  actuarial
determination of our pension expense and 5.85 percent in our actuarial determination of our other postretirement expense. The actuarial determination uses
an asset smoothing methodology for actual returns to reduce the volatility of varying investment performance over time. We review our expected long-term
rate of return assumption annually and will adjust it to respond to changing market conditions. A one-quarter percent decrease in the expected long-term
rate of return would increase the annual expense for pension and other postretirement benefits by approximately $2.0 million, pre-tax.

The discount rate is computed using a bond matching study which utilizes a portfolio of high quality bonds that produce cash flows similar to the projected
costs of our pension and other postretirement plans. In 2021, we used weighted average discount rates of 2.87 percent and 2.70 percent in our actuarial
determination  of  our  pension  and  other  postretirement  expense,  respectively.  We  review  our  discount  rates  annually  and  will  adjust  them  to  respond  to
changing market conditions. A one-quarter percent decrease in the discount rate would increase the annual expense for pension and other postretirement
benefits by approximately $1.7 million, pre-tax.

The mortality assumptions used to calculate our pension and other postretirement benefit obligations as of December 31, 2021, considered a modified PRI-
2012 mortality table and MP-2021 mortality projection scale. (See Note 11. Pension and Other Postretirement Benefit Plans.)

Impairment  of  Long-Lived  Assets.  We  review  our  long-lived  assets  for  indicators  of  impairment  in  accordance  with  the  accounting  standards  for
property, plant and equipment on a quarterly basis.

In  accordance  with  the  accounting  standards  for  property,  plant  and  equipment,  if  indicators  of  impairment  exist,  we  test  our  long‑lived  assets  for
recoverability by comparing the carrying amount of the asset to the undiscounted future net cash flows expected to be generated by the asset. Cash flows
are assessed at the lowest level of identifiable cash flows. The undiscounted future net cash flows are impacted by trends and factors known to us at the
time they are calculated and our expectations related to: management’s best estimate of future sales prices; holding period and timing of sales; method of
disposition; and future expenditures necessary to maintain the operations.

Taxation. We are required to make judgments regarding the potential tax effects of various financial transactions and our ongoing operations to estimate
our  obligations  to  taxing  authorities.  These  tax  obligations  include  income  taxes  and  taxes  other  than  income  taxes.  Judgments  related  to  income  taxes
require the recognition in our financial statements of the largest tax benefit of a tax position that is “more-likely-than-not” to be sustained on audit. Tax
positions that do not meet the “more-likely-than-not” criteria are reflected as a tax liability in accordance with the accounting standards for uncertainty in
income taxes. We record a valuation allowance against our deferred tax assets to the extent it is more-likely-than-not that some portion or all of the deferred
tax assets will not be realized.

We  are  subject  to  income  taxes  in  various  jurisdictions.  We  make  assumptions  and  judgments  each  reporting  period  to  estimate  our  income  tax  assets,
liabilities, benefits and expenses. Judgments and assumptions are supported by historical data and reasonable projections. Our assumptions and judgments
include the application of tax statutes and regulations, and projections of future federal taxable income, state taxable income, and state apportionment to
determine our ability to utilize NOL and credit carryforwards prior to their expiration. Significant changes in assumptions regarding future federal and state
taxable  income  or  a  change  in  tax  rates  could  require  new  or  increased  valuation  allowances  which  could  result  in  a  material  impact  on  our  results  of
operations.

Outlook

ALLETE  is  an  energy  company  committed  to  earning  a  financial  return  that  rewards  our  shareholders,  allows  for  reinvestment  in  our  businesses,  and
sustains growth. The Company has a long-term objective of achieving consolidated average annual earnings per share growth within a range of 5 percent to
7 percent.

ALLETE  is  predominately  a  regulated  utility  through  Minnesota  Power,  SWL&P,  and  an  investment  in  ATC.  ALLETE’s  strategy  is  to  remain
predominately a regulated utility while investing in ALLETE Clean Energy and its Corporate and Other businesses to complement its regulated businesses,
balance  exposure  to  the  utility’s  industrial  customers,  and  provide  potential  long-term  earnings  growth.  ALLETE  expects  net  income  from  Regulated
Operations  to  be  approximately  75  percent  of  total  consolidated  net  income  in  2022.  Over  the  next  several  years,  the  contribution  of  ALLETE  Clean
Energy and our Corporate and Other businesses to net income is expected to increase as ALLETE grows these operations. ALLETE expects its businesses
to provide regulated, contracted or recurring revenues, and to support sustained growth in net income and cash flow.

Regulated Operations. Minnesota Power’s long-term strategy is to be the leading electric energy provider in northeastern Minnesota by providing safe,
reliable and cost-competitive electric energy, while complying with environmental permit conditions and renewable energy requirements. Keeping the cost
of energy production competitive enables Minnesota Power to effectively compete in the wholesale power markets and minimizes retail rate increases to
help maintain customer viability. As part of maintaining cost competitiveness, Minnesota Power intends to reduce its exposure to possible future carbon
and GHG legislation by reshaping its generation portfolio, over time, to reduce its reliance on coal. Minnesota Power has a goal of delivering 100 percent
carbon-free  energy  by  2050.  (See  EnergyForward.)  We  will  monitor  and  review  proposed  environmental  regulations  and  may  challenge  those  that  add
considerable  cost  with  limited  environmental  benefit.  Minnesota  Power  will  continue  to  pursue  customer  growth  opportunities  and  cost  recovery  rider
approvals for transmission, renewable and environmental investments, as well as work with regulators to earn a fair rate of return.

Regulatory Matters. Entities within our Regulated Operations segment are under the jurisdiction of the MPUC, FERC, PSCW and NDPSC. See Note 4.
Regulatory Matters for discussion of regulatory matters within these jurisdictions.

2022  Minnesota  General  Rate  Case.  On  November  1,  2021,  Minnesota  Power  filed  a  retail  rate  increase  request  with  the  MPUC  seeking  an  average
increase of approximately 18 percent for retail customers. The rate filing seeks a return on equity of 10.25 percent and a 53.81 percent equity ratio. On an
annualized basis, the requested final rate increase would generate approximately $108 million in additional revenue. In orders dated December 30, 2021,
the  MPUC  accepted  the  filing  as  complete  and  authorized  an  annual  interim  rate  increase  beginning  January  1,  2022,  with  approximately  $80  million
expected to be collected in cash and approximately $8 million of interim rates for residential customers deferred with a final determination on recovery at
the end of the rate case.

Minnesota Power Land Sales. In August 2020, Minnesota Power filed a petition with the MPUC for approval to sell land that surrounds several reservoirs
on  its  hydroelectric  system  and  is  no  longer  required  to  maintain  its  operations.  The  land  has  an  estimated  value  of  approximately  $100  million,  and
Minnesota Power proposed to credit ratepayers the net proceeds from the sales in a future rate case or through its renewable resources rider to mitigate
future rate increases. In an order dated November 18, 2021, the MPUC authorized the land sales and directed the net proceeds to be refunded to ratepayers
subject to certain conditions and required compliance filings.

Wisconsin General Rate Case. SWL&P expects to file its next general rate case in 2022. The PSCW granted an extension request made by SWL&P to
delay filing its next general rate case until on or before December 20, 2022. SWL&P requested the extension primarily due to impacts of the COVID-19
pandemic.

Outlook (Continued)

Industrial Customers and Prospective Additional Load

Industrial Customers.  Electric  power  is  one  of  several  key  inputs  in  the  taconite  mining,  paper,  pulp  and  secondary  wood  products,  pipeline  and  other
industries. Approximately 47 percent of our regulated utility kWh sales in 2021 (47 percent in 2020 and 54 percent in 2019) were made to our industrial
customers.  We  expect  industrial  sales  of  approximately  6.5  million  MWh  in  2022  (7.2  million  MWh  in  2021  and  6.2  million  in  2020).  (See  Item  1.
Business – Regulated Operations – Electric Sales / Customers.)

Taconite. Minnesota Power’s taconite customers are capable of producing up to approximately 41 million tons of taconite pellets annually. Taconite pellets
produced in Minnesota are primarily shipped to North American steel making facilities that are part of the integrated steel industry, which continue to lead
the world in environmental performance among steelmaking countries. According to the U.S. Department of Energy, steel production in the U.S. is the
most energy efficient of any major steel producing country. Steel produced from these North American facilities is used primarily in the manufacture of
automobiles,  appliances,  tubular  applications  for  all  industries,  and  in  the  construction  industry.  Steel  is  also  a  critical  component  of  the  clean  energy
transformation underway today. Meeting the demand for more renewable energy and the need for additional infrastructure to transport green energy from
the point of generation to the end user both require steel. Historically, less than 10 percent of Minnesota taconite production has been exported outside of
North America.

There has been a general historical correlation between U.S. steel production and Minnesota taconite production. The American Iron and Steel Institute, an
association  of  North  American  steel  producers,  reported  that  U.S.  raw  steel  production  operated  at  approximately  82  percent  of  capacity  in  2021  (68
percent in 2020 and 80 percent in 2019). The World Steel Association, an association of steel producers, national and regional steel industry associations,
and steel research institutes representing approximately 85 percent of world steel production, projected U.S. steel consumption in 2022 will increase by
approximately 6 percent compared to 2021.

Minnesota  Power’s  taconite  customers  may  experience  annual  variations  in  production  levels  due  to  such  factors  as  economic  conditions,  short-term
demand  changes  or  maintenance  outages.  We  expect  taconite  production  from  our  taconite  customers  of  approximately  35  million  tons  in  2022.  We
estimate that a one million ton change in Minnesota Power’s taconite customers’ production would impact our annual earnings per share by approximately
$0.04, net of expected power marketing sales at current prices. Changes in wholesale electric prices or customer contractual demand nominations could
impact this estimate. Minnesota Power proactively sells power in the wholesale power markets that is temporarily not required by industrial customers to
optimize  the  value  of  its  generating  facilities.  Long-term  reductions  in  taconite  production  or  a  permanent  shut  down  of  a  taconite  customer  may  lead
Minnesota Power to file a general rate case to recover lost revenue.

USS Corporation. In April 2020, USS Corporation stated it would idle its Keetac facility in Keewatin, Minnesota, in response to the sudden and dramatic
decline  in  business  conditions  resulting  from  the  COVID-19  pandemic.  In  addition,  in  May  2020,  USS  Corporation  announced  that  production  was
expected to be temporarily reduced at its Minntac Plant in Mountain Iron, Minnesota. USS Corporation resumed normal production at its Minntac Plant
beginning in late July 2020 and resumed operations at its Keetac facility in December 2020. In October 2021, USS Corporation announced that it will be
increasing its blast furnace operating rates at its Gary, Indiana steel mill through the installation of a 500,000 ton per year pig iron caster. When completed
in early 2023, the pig iron produced from Minnesota iron ore would be used at USS Corporation’s Big River steel making facility in Osceola, Arkansas.
USS Corporation has the capability to produce approximately 15 million and 5 million tons annually at its Minntac and Keetac plants, respectively.

Cliffs.  In  December  2020,  Cliffs  announced  that  it  had  completed  the  previously  announced  acquisition  of  substantially  all  of  the  operations  of
ArcelorMittal USA LLC and its subsidiaries. Cliffs had stated that upon closure of the acquisition Cliffs would be the largest flat-rolled steel producer and
the largest iron ore pellet producer in North America. The acquisition included ArcelorMittal’s Minorca mine in Virginia, Minnesota, and its ownership
share of Hibbing Taconite in Hibbing, Minnesota, which are both large industrial customers of Minnesota Power. Cliffs is now Minnesota Power’s largest
customer. The acquisition has increased customer concentration risk for the Company and could lead to further capacity consolidation for both steel blast
furnaces and the related Minnesota iron ore production.

Cliffs  completed  construction  of  a  hot  briquetted  iron  production  plant  in  Toledo,  Ohio,  in  2020,  which  has  utilized  direct  reduced-grade  pellets  from
Northshore  Mining.  In  October  2021,  Cliffs  indicated  it  plans  to  move  direct  reduced-grade  pellet  production  to  its  Minorca  mine  and  that  Northshore
Mining would become a “swing facility” due to the higher royalty rates at that mine. (See Northshore Mining.).

ALLETE, Inc. 2021 Form 10-K

Outlook (Continued)
Industrial Customers and Prospective Additional Load (Continued)

Northshore Mining.  In  April  2020,  Cliffs  announced  that,  based  on  market  conditions,  it  would  be  temporarily  idling  Northshore  Mining.  Cliffs  idled
production at Northshore Mining in April 2020 and resumed normal production at the facility in August 2020. On February 11, 2022, Cliffs announced that
with the use of additional scrap in its basic oxygen furnaces, iron ore needs are not as high as before. When determining where to adjust production, Cliffs
decided to idle all production at its Northshore mine. Cliffs anticipated that the Northshore mine will be temporarily idled for approximately four months
during  2022.  Cliffs  also  indicated  that  going  forward  it  will  be  limiting  the  tonnage  of  iron  ore  pellets  sold  to  third  parties.  Northshore  Mining  has  the
capability  to  produce  approximately  6  million  tons  annually.  Minnesota  Power  has  a  PSA  through  2031  with  Silver  Bay  Power,  which  provides  the
majority of the electric service requirements for Northshore Mining. (See Silver Bay Power and Cliffs.)

Silver Bay Power. In 2016, Minnesota Power and Silver Bay Power entered into a PSA through 2031. Silver Bay Power supplies approximately 90 MW of
load to Northshore Mining, an affiliate of Silver Bay Power, which had previously been served predominately through self-generation by Silver Bay Power.
Starting in 2016, Minnesota Power supplied Silver Bay Power with at least 50 MW of energy and Silver Bay Power had the option to purchase additional
energy  from  Minnesota  Power  as  it  transitioned  away  from  self-generation.  In  the  third  quarter  of  2019,  Silver  Bay  Power  ceased  self-generation  and
Minnesota Power began supplying the full energy requirements for Silver Bay Power.

Hibbing Taconite.  In  April  2020,  ArcelorMittal  announced  that  Hibbing  Taconite  in  Hibbing,  Minnesota,  would  idle  production  due  to  the  COVID-19
pandemic. Hibbing Taconite resumed normal production in August 2020. Hibbing Taconite’s current mineable ore reserves are expected to be exhausted in
2025. Cliffs, which in December 2020 became majority owner and resumed management of Hibbing Taconite, has stated that it has a plan to extend the
mine life of Hibbing Taconite with ore reserves already under control of Cliffs. There are ample ore reserves in northeastern Minnesota that could supply
operations  for  decades  to  come,  and  Minnesota  Power’s  taconite  customers  routinely  develop  and  extend  their  mine  plans  to  optimize  assets.  Hibbing
Taconite has the capability to produce approximately 8 million tons annually.

Minnesota Sulfate Wild Rice Water Quality Standard. On April 29, 2021, the EPA identified rivers and lakes in Minnesota in which wild rice grows that
have sulfate levels that exceed Minnesota’s sulfate limit for wild rice waters. On September 1, 2021, three additional wild rice waters with sulfate levels
that exceed Minnesota’s sulfate limit were identified. The EPA directed the MPCA to add these rivers and lakes to its list of impaired waters which can be
used to set limits in discharge permits for industrial activities such as mining. Minnesota Power’s taconite customers could be adversely impacted if they
are required to significantly reduce sulfate discharges.

Paper,  Pulp  and  Secondary  Wood  Products.  The  North  American  paper  and  pulp  industry  faces  declining  demand  due  to  the  impact  of  electronic
substitution for print and changing customer needs. As a result, certain paper and pulp customers have reduced their existing operations in recent years and
have pursued or are pursuing product changes in response to the declining demand. We expect operating levels in 2022 at the major paper and pulp mills
we serve to be lower than in 2021 as several customers operated at higher than normal levels in 2021.

Verso Corporation and ST Paper. In June 2020, Verso Corporation indefinitely idled its paper mill in Duluth, Minnesota (Duluth Mill). Verso Corporation
stated the decision was due to the accelerated decline in graphic paper demand resulting from the COVID-19 pandemic and has disclosed it is considering
options  for  the  Duluth  Mill,  including  marketing  for  a  sale.  On  January  29,  2021,  Verso  Corporation  provided  notice  of  termination  for  its  contract.
Minnesota Power and Verso Corporation mutually agreed to resolve the outstanding commitments under the contract in January 2022. In May 2021, Verso
Corporation announced the completion of the sale of the Duluth Mill to ST Paper LLC (ST Paper). ST Paper has stated it plans to convert the Duluth Mill
to  produce  tissue.  In  January  2022,  Minnesota  Power  entered  into  an  electric  service  agreement  with  ST  Paper,  subject  to  MPUC  approval,  that  would
begin Large Power customer service with a minimum term of 6-years upon start-up of operations, which is anticipated in 2023. The agreement will qualify
as a Large Power customer contract as we expect to serve requirements of at least 10 MW of customer load.

Pipeline and Other Industries.

Cenovus Energy. In 2018, a fire at Cenovus Energy’s refinery in Superior, Wisconsin, which was owned by Husky Energy at that time, disrupted operations
at the facility. Under normal operating conditions, SWL&P provides approximately 14 MW of average monthly demand to the refinery in addition to water
service. The facility remains at minimal operations, and the refinery is not expected to resume normal operations until 2023.

Outlook (Continued)
Industrial Customers and Prospective Additional Load (Continued)

Prospective Additional Load. Minnesota Power is pursuing new wholesale and retail loads in and around its service territory. Currently, several companies
in northeastern Minnesota continue to progress in the development of natural resource-based projects that represent long-term growth potential and load
diversity for Minnesota Power. We cannot predict the outcome of these projects.

PolyMet. PolyMet is planning to start a new copper-nickel and precious metal (non-ferrous) mining operation in northeastern Minnesota. In 2015, PolyMet
announced  the  completion  of  the  final  EIS  by  state  and  federal  agencies,  which  was  subsequently  published  in  the  Federal  Register  and  Minnesota
Environmental Quality Board Monitor. The Minnesota Department of Natural Resources (DNR) and the U.S. Army Corps of Engineers have both issued
final Records of Decision, finding the final EIS adequate.

PolyMet was issued all necessary permits to construct and operate its new mining operation; however, of the more than 20 permits issued to build and
operate  the  mine,  three  permits  remain  on  hold  pending  legal  or  regulatory  action,  which  is  expected  to  continue  during  2022.  Minnesota  Power  could
supply between 45 MW and 50 MW of load under a 10-year power supply contract with PolyMet that would begin upon start-up of operations.

EnergyForward.  Minnesota  Power  is  executing  EnergyForward,  its  strategy  assuring  reliability,  protecting  affordability  and  further  improving
environmental  performance.  The  plan  includes  completed  and  planned  investments  in  wind,  solar,  natural  gas  and  hydroelectric  power,  construction  of
additional transmission capacity, the installation of emissions control technology and the idling and retirement of certain coal-fired generating facilities.
Minnesota  Power  has  a  vision  to  deliver  100  percent  carbon-free  energy  to  customers  by  2050,  continuing  its  commitment  to  climate,  customers  and
communities through its EnergyForward strategy. This vision builds on Minnesota Power’s recent achievement of now providing 50 percent renewable
energy to its customers.

2021 Integrated Resource Plan. On February 1, 2021, Minnesota Power filed its latest IRP with the MPUC, which outlines its clean-energy transition plans
through 2035. These plans include expanding its renewable energy supply to 70 percent by 2030, achieving coal-free operations at its facilities by 2035,
and  investing  in  a  resilient  and  flexible  transmission  and  distribution  grid.  Minnesota  Power  has  also  set  a  target  to  achieve  an  80  percent  reduction  in
carbon emissions by 2035 compared to 2005 levels. As part of these plans, Minnesota Power anticipates adding approximately 400 MW of new wind and
solar energy resources, retiring Boswell Unit 3 by 2030 and transforming Boswell Unit 4 to be coal-free by 2035. Minnesota Power’s plans recognize that
advances in technology will play a significant role in completing its transition to carbon-free energy supply, reliably and affordably. A final decision on the
IRP is expected in the second half of 2022.

In recent years, Minnesota Power has transformed its energy supply from more than a 95 percent reliance on coal to become a leader in the nation’s clean-
energy transformation. Since 2013, the company has closed or converted seven of its nine coal-fired units and added nearly 900 megawatts of renewable
energy sources. Additionally, Minnesota Power has been a leader in energy conservation, surpassing the state’s conservation goals each year for the past
decade.

Nemadji Trail Energy Center. In 2017, Minnesota Power submitted a resource package to the MPUC which included requesting approval of a natural gas
capacity dedication and other affiliated-interest agreements for NTEC, an approximately 600 MW proposed combined-cycle natural gas-fired generating
facility to be built in Superior, Wisconsin, which will be jointly owned by Dairyland Power Cooperative, Basin and South Shore Energy, ALLETE’s non-
rate regulated, Wisconsin subsidiary. Minnesota Power is expected to purchase approximately 20 percent of the facility's output starting in 2025 pursuant to
the capacity dedication agreement.

Renewable Energy. Minnesota Power continues to execute its renewable energy strategy and recently reached its goal of supplying 50 percent of its energy
by renewable energy sources. Minnesota Power also has a goal of delivering 100 percent carbon-free energy by 2050. (See EnergyForward.)

Minnesota Power has approved cost recovery riders for certain renewable investments and expenditures as well as investments and expenditures related to
compliance with the Minnesota Solar Energy Standard. The cost recovery riders allow Minnesota Power to charge retail customers on a current basis for
the costs of certain renewable and solar investments and expenditures plus a return on the capital invested. (See Note 4. Regulatory Matters.)

Wind Energy. Minnesota  Power’s  wind  energy  facilities  consist  of  Bison  (497  MW)  located  in  North  Dakota,  and  Taconite  Ridge  (25  MW)  located  in
northeastern Minnesota. Minnesota Power also has two long-term wind energy PPAs with an affiliate of NextEra Energy, Inc. to purchase the output from
Oliver Wind I (50 MW) and Oliver Wind II (48 MW) located in North Dakota.

Minnesota Power uses the 465-mile, 250-kV DC transmission line that runs from Center, North Dakota, to Duluth, Minnesota, to transport wind energy
from North Dakota while gradually phasing out coal-based electricity delivered to its system over this transmission line from Square Butte’s lignite coal-
fired generating unit. Minnesota Power is currently pursuing a modernization and capacity upgrade of its DC transmission system to continue providing
reliable operations and additional system capabilities.

Nobles 2 PPA. Minnesota Power has a long-term PPA with Nobles 2 that provides for Minnesota Power to purchase the energy and associated capacity
from a 250 MW wind energy facility in southwestern Minnesota through 2040. The agreement provides for the purchase of output from the facility at fixed
energy prices. There are no fixed capacity charges, and Minnesota Power will only pay for energy as it is delivered. (See Corporate and Other – Investment
in Nobles 2.)

Manitoba Hydro. Minnesota Power has three long-term PPAs with Manitoba Hydro. Under the first PPA, Minnesota Power is purchasing surplus energy
through April 2022. This energy-only agreement primarily consists of surplus hydro energy on Manitoba Hydro’s system that is delivered to Minnesota
Power on a non-firm basis. Under this agreement, Minnesota Power will purchase at least one million MWh of energy over the contract term. The second
PPA provides for Minnesota Power to purchase 250 MW of capacity and energy from Manitoba Hydro through May 2035. The third PPA provides for
Minnesota  Power  to  purchase  up  to  133  MW  of  energy  from  Manitoba  Hydro  through  June  2040.  (See  Note  8.  Commitments,  Guarantees  and
Contingencies.)

Solar  Energy.  Minnesota  Power’s  solar  energy  supply  consists  of  Camp  Ripley,  a  10  MW  solar  energy  facility  at  the  Camp  Ripley  Minnesota  Army
National Guard base and training facility near Little Falls, Minnesota, and a community solar garden in northeastern Minnesota, which is comprised of a 1
MW solar array owned and operated by a third party with the output purchased by Minnesota Power and a 40 kW solar array that is owned and operated by
Minnesota Power. SWL&P also plans to construct a 470 kW solar array in 2022 as part of a community solar garden in Superior, Wisconsin, which was
approved by the PSCW in October 2020.

In June 2020, Minnesota Power filed a proposal with the MPUC to accelerate its plans for purchasing solar energy from approximately 20 MW of solar
energy projects in Minnesota which was approved in a June 2021 order. These solar energy projects will be constructed and owned through an ALLETE
subsidiary with an estimated investment of $40 million. Construction of these solar energy projects is expected to commence in 2022.

Transmission. We continue to make investments in transmission opportunities that strengthen or enhance the transmission grid or take advantage of our
geographical  location  between  sources  of  renewable  energy  and  end  users.  These  include  the  GNTL,  investments  to  enhance  our  own  transmission
facilities,  investments  in  other  transmission  assets  (individually  or  in  combination  with  others)  and  our  investment  in  ATC.  See  Item  1.  Business  –
Regulated Operations and Note 8. Commitments, Guarantees and Contingencies.

Duluth Loop Reliability Project. On October 21, 2021, Minnesota Power submitted an application for a certificate of need for the Duluth Loop Reliability
Project. This transmission project was proposed to enhance reliability in and around Duluth, Minnesota. The project includes the construction of a new 115-
kV transmission line; construction of an approximately one-mile extension of an existing 230-kV transmission line; and upgrades to several substations.
The Duluth Loop Reliability Project is expected to be completed and in service by 2025, subject to MPUC approval, with an estimated cost of $50 million
to $70 million.

ALLETE Clean Energy.

ALLETE  Clean  Energy  will  pursue  growth  through  acquisitions  or  project  development.  ALLETE  Clean  Energy  is  targeting  acquisitions  of  existing
operating portfolios which have a mix of long-term PSAs in place and/or available for repowering and recontracting. Further, ALLETE Clean Energy will
evaluate  actions  that  will  lead  to  the  addition  of  complimentary  clean  energy  products  and  services.  At  this  time,  ALLETE  Clean  Energy  expects
acquisitions or development of new facilities will be primarily wind, solar, energy storage or storage ready facilities across North America. ALLETE Clean
Energy is also targeting the development of new facilities up to 300 MW each, which will have long-term PSAs in place for the output or may be sold upon
completion.

Outlook (Continued)
ALLETE Clean Energy (Continued)

Portions  of  our  ALLETE  Clean  Energy  business  are  experiencing  return  pressures  that  are  impacting  our  earnings  per  share  growth  from  increased
competition, and lower forward price curves, as a growing amount of investment capital is being directed into wind generation opportunities. In addition,
current and potential new project developments can be negatively affected by a lower ALLETE stock price, which may result in such projects not being
accretive,  or  otherwise  unable  to  satisfy  our  financial  objectives  criteria  to  proceed.  In  response  to  these  market  pressures,  we  are  actively  evaluating
additional growth opportunities to deliver more comprehensive clean energy solutions for customers at ALLETE Clean Energy, which may include solar,
storage  solutions,  and  related  energy  infrastructure  investments  and  services.  We  believe  that  the  renewable  energy  industry  is  entering  a  new  phase  of
growth  and  that  we  are  well-positioned  to  serve  customers  and  drive  future  growth  at  ALLETE.  ALLETE  Clean  Energy  will  continue  to  optimize  its
existing  wind  energy  facility  portfolio,  seek  development  of  its  remaining  safe  harbor  inventory  of  tax  credit  qualified  turbines,  and  explore  other
renewable energy opportunities to expand its service offerings to further enhance its growth and profitability.

Federal production tax credit qualification is important to the economics of project development, and ALLETE Clean Energy has invested in equipment to
meet production tax credit safe harbor provisions which provides an opportunity to seek development of its remaining safe harbor production tax credit
qualified equipment through 2025 based on the most recent PTC safe harbor extension by the IRS. ALLETE Clean Energy has completed its investment of
approximately  $80  million  for  production  tax  credit  requalification  of  approximately  470  WTGs  at  its  Storm  Lake  I,  Storm  Lake  II,  Lake  Benton  and
Condon wind energy facilities. We anticipate annual production tax credits relating to these projects of approximately $17 million to $22 million annually
through 2027 and decreasing thereafter through 2030. Disruptions in our supply chains or a lack of available financing resulting from the ongoing COVID-
19 pandemic, if they occur, could jeopardize our ability to complete certain capital projects in time to qualify them for production tax credits. To date we
have not experienced disruptions in our supply chains related to the COVID-19 pandemic.

In March 2020, ALLETE Clean Energy acquired the rights to the approximately 300 MW Caddo wind development project in Oklahoma from Apex Clean
Energy. The Caddo wind project is fully contracted to sell wind power under long-term power sales agreements; construction was completed and tax equity
funding of $62.0 million of cash, net of issuance costs, was received in the fourth quarter of 2021 with an additional $183.0 million of cash, net of issuance
costs, received in January 2022. Also in January 2022, ALLETE Clean Energy acquired a portion of the non-controlling interest for its Caddo wind energy
facility for approximately $30 million.

On February 4, 2021, ALLETE Clean Energy entered into a purchase and sale agreement with a subsidiary of Xcel Energy Inc. to sell a 100 MW wind
energy facility for approximately $185 million. ALLETE Clean Energy will repower its Northern Wind project, consisting of its 98 MW Chanarambie and
Viking wind energy facilities located in southwest Minnesota, as part of the transaction. Construction is expected to begin in 2022 with the Northern Wind
project expected to continue operating until the second quarter of 2022. At a hearing in June 2021, the MPUC approved the sale, which is expected to close
in late 2022, subject to completion of construction and receipt of permits. ALLETE Clean Energy has experienced inflationary increases and significant
cost pressures related to this project and as a result now anticipates a loss on sale of the project, which resulted in an approximately $2 million after-tax
charge in the fourth quarter of 2021.

In  May  2021,  ALLETE  Clean  Energy  announced  that  it  acquired  the  rights  to  the  approximately  92  MW  Red  Barn  wind  development  project  and  the
approximately 68 MW Whitetail renewable development project in southwestern Wisconsin. ALLETE Clean Energy also signed an asset sale agreement
for the completed Red Barn wind project with Wisconsin Public Service Corporation and Madison Gas and Electric Company. At a hearing in January
2022, the PSCW approved the sale of the Red Barn wind project, which is expected to close in 2023, subject to completion of construction and receipt of
permits.

Outlook (Continued)
ALLETE Clean Energy (Continued)

ALLETE Clean Energy manages risk by having a diverse portfolio of assets, which includes PSA expiration, technology and geographic diversity. The
current  operating  portfolio  is  subject  to  typical  variations  in  seasonal  wind  with  higher  wind  resources  typically  available  in  the  winter  months.  The
majority  of  its  planned  maintenance  leverages  this  seasonality  and  is  performed  during  lower  wind  periods.  ALLETE  Clean  Energy’s  current  operating

(a) The PSA expiration assumes the exercise of four one-year renewal options that ALLETE Clean Energy has the sole right to exercise.

Non-cash amortization to revenue recognized by ALLETE Clean Energy relates to the amortization of differences between contract prices and estimated
market prices on assumed PSAs. As part of wind energy facility acquisitions, ALLETE Clean Energy assumed various PSAs that were above or below
estimated market prices at the time of acquisition; the resulting differences between contract prices and estimated market prices are amortized to revenue
over the remaining PSA term. Non-cash amortization is expected to be approximately $7 million in 2022, $5 million in 2023, $6 million annually in 2024
through 2027, and decreasing thereafter through 2032.

Corporate and Other.

BNI Energy. In 2021, BNI Energy sold 3.9 million tons of coal (4.2 million tons in 2020) and anticipates 2022 sales will be similar to 2021. BNI Energy
operates under cost-plus fixed fee agreements extending through December 31, 2037.

Investment in Nobles 2. Our subsidiary, ALLETE South Wind, owns a 49 percent equity interest in Nobles 2, the entity that owns and operates a 250 MW
wind energy facility in southwestern Minnesota pursuant to a 20-year PPA with Minnesota Power. We account for our investment in Nobles 2 under the
equity method of accounting. (See Note 5. Equity Investments.)

Outlook (Continued)
Corporate and Other (Continued)

South Shore Energy. South Shore Energy, ALLETE’s non-rate regulated, Wisconsin subsidiary, is developing NTEC, an approximately 600 MW proposed
combined-cycle natural gas-fired generating facility to be built in Superior, Wisconsin, which will be jointly owned by Dairyland Power Cooperative, Basin
and South Shore Energy. Minnesota Power is expected to purchase approximately 20 percent of the facility's output starting in 2025 pursuant to a capacity
dedication agreement. Construction of NTEC is subject to obtaining additional permits from local, state and federal authorities. The total project cost is
estimated to be approximately $700 million, of which South Shore Energy’s portion is expected to be approximately $150 million. South Shore Energy’s
portion of NTEC project costs incurred through December 31, 2021, is approximately $5 million.

On  October  1,  2021,  South  Shore  Energy  sold  a  portion  of  its  undivided  ownership  interest  in  NTEC  for  approximately  $20  million  representing
reimbursement of current costs plus a fee for prior development costs and risks incurred. Following the transaction, South Shore Energy now owns a 20
percent  undivided  ownership  interest  in  NTEC,  Basin  owns  a  30  percent  undivided  ownership  interest  in  NTEC  and  Dairyland  Power  Cooperative
continues to own a 50 percent undivided ownership interest in NTEC. The closing of the transaction resulted in the recognition of an approximately $8.5
million after-tax gain recorded in Corporate and Other in the fourth quarter of 2021, related to prior development costs and risks incurred.

ALLETE Properties. Our strategy incorporates the possibility of a bulk sale of the entire ALLETE Properties portfolio. Proceeds from a bulk sale would be
strategically deployed to support growth initiatives at our Regulated Operations and ALLETE Clean Energy. ALLETE Properties also continues to pursue
sales of individual parcels over time and will continue to maintain key entitlements and infrastructure.

Income Taxes

ALLETE’s  aggregate  federal  and  multi-state  statutory  tax  rate  is  approximately  28  percent  for  2021.  ALLETE  also  has  tax  credits  and  other  tax
adjustments that reduce the combined statutory rate to the effective tax rate. These tax credits and adjustments historically have included items such as
production tax credits, excess deferred taxes, non-controlling interests in subsidiaries, as well as other items. The annual effective rate can also be impacted
by such items as changes in income before income taxes, state and federal tax law changes that become effective during the year, business combinations,
tax  planning  initiatives  and  resolution  of  prior  years’  tax  matters.  We  expect  our  effective  tax  rate  to  be  a  benefit  of  approximately  5  percent  for  2022
primarily due to federal production tax credits as a result of wind energy generation and non-controlling interests in subsidiaries. We also expect that our
effective  tax  rate  will  be  lower  than  the  combined  statutory  rate  over  the  next  10  years  due  to  production  tax  credits  attributable  to  our  wind  energy
generation.

Liquidity and Capital Resources

Liquidity Position.  ALLETE  is  well-positioned  to  meet  its  liquidity  needs;  however,  the  Company  is  monitoring  capital  markets  and  other  financing
sources in light of the ongoing COVID-19 pandemic. (See Item 1A. Risk Factors.) A disruption in capital markets could lead to increased borrowing costs
or adversely impact our ability to access capital markets or other financing sources. If we are not able to access capital on acceptable terms in sufficient
amounts and when needed, or at all, the ability to maintain our businesses or to implement our business plans would be adversely affected.

As of December 31, 2021, we had cash and cash equivalents of $45.1 million, $240.8 million in available consolidated lines of credit, 2.1 million original
issue  shares  of  common  stock  available  for  issuance  through  a  distribution  agreement  with  Lampert  Capital  Markets  and  a  debt-to-capital  ratio  of
40 percent.

Operating Activities. Cash  from  operating  activities  was  lower  in  2021  compared  to  2020.  Cash  from  operating  activities  in  2021  included  lower  net
income and higher payments for inventories compared to 2020, and was negatively impacted by the timing of recovery and refund of the fuel adjustment
clause.

Cash from operating activities was higher in 2020 compared to 2019. Cash from operating activities in 2019 included the refund of Minnesota Power’s
provisions for interim rates and tax reform, and the impact of U.S. Water Services prior to its sale. Cash from operating activities in 2020 included lower
collections of accounts receivable due to timing.

Investing Activities.  Cash  used  for  investing  activities  was  lower  in  2021  compared  to  2020.  Cash  used  for  investing  activities  in  2021  reflected  lower
additions to property, plant and equipment and lower payments for equity method investments compared to 2020.

Cash used for investing activities in 2020 was higher compared to 2019. Cash used for investing activities in 2020 included higher additions to property,
plant  and  equipment  and  additional  payments  for  equity  method  investments  compared  to  2019.  Cash  used  for  investing  activities  in  2019  included
proceeds received from the sale of U.S. Water Services.

Financing Activities. Cash from financing activities was lower in 2021 compared to 2020 primarily due to lower proceeds from non-controlling interest in
subsidiaries and higher repayments of short-term and long-term debt in 2021. These decreases were partially offset by higher proceeds from the issuance of
common stock and higher proceeds from the issuance of short-term and long-term debt in 2021.

Liquidity and Capital Resources (Continued)
Cash Flows (Continued)

Cash from financing activities was higher in 2020 compared to 2019 primarily due to higher proceeds from the issuance of long-term debt and proceeds
from a tax equity financing (non-controlling interest in subsidiaries) in 2020. These increases were partially offset by higher repayments of long-term debt
in 2020.

Working Capital. Additional working capital, if and when needed, generally is provided by consolidated bank lines of credit and the issuance of securities,
including  long-term  debt,  common  stock  and  commercial  paper.  As  of  December  31,  2021,  we  had  consolidated  bank  lines  of  credit  aggregating
$432.0 million ($407.0 million as of December 31, 2020), most of which expire in January 2025. We had $31.5 million outstanding in standby letters of
credit and $159.7 million outstanding draws under our lines of credit as of December 31, 2021 ($22.3 million in standby letters of credit and no outstanding
draws as of December 31, 2020). We also have other credit facility agreements in place that provide the ability to issue up to $100.0 million in standby
letters of credit. As of December 31, 2021, we had $91.2 million outstanding in standby letters of credit under these agreements.

In  January  2022,  ALLETE  Clean  Energy  received  approximately  $183.0  million  from  final  closing  of  tax  equity  funding  for  the  Caddo  wind  energy
facility. The proceeds from the funding were used to pay down a portion of outstanding draws on our lines of credit.

In  addition,  as  of  December  31,  2021,  we  had  3.1  million  original  issue  shares  of  our  common  stock  available  for  issuance  through  Invest  Direct  and
2.1 million original issue shares of common stock available for issuance through a distribution agreement with Lampert Capital Markets. (See Securities.)
The amount and timing of future sales of our securities will depend upon market conditions and our specific needs.

Securities.  We  entered  into  a  distribution  agreement  with  Lampert  Capital  Markets,  in  2008,  as  amended  most  recently  in  2020,  with  respect  to  the
issuance and sale of up to an aggregate of 13.6 million shares of our common stock, without par value, of which 2.1 million shares remain available for
issuance as of December 31, 2021. For the year ended December 31, 2021, 0.8 million shares of common stock were issued under this agreement resulting
in net proceeds of $51.0 million (none in 2020 and 2019).

During the year ended December 31, 2021, we issued 0.3 million shares of common stock through Invest Direct, the Employee Stock Purchase Plan and
the Retirement Savings and Stock Ownership Plan, resulting in net proceeds of $18.9 million (0.4 million shares for net proceeds of $18.1 million in 2020;
0.2 million shares for net proceeds of $1.9 million in 2019). See Note 9. Common Stock and Earnings Per Share for additional detail regarding ALLETE’s
equity securities.

Financial Covenants. See Note 7. Short-Term and Long-Term Debt for information regarding our financial covenants.

Pension  and  Other  Postretirement  Benefit  Plans.  Management  considers  various  factors  when  making  funding  decisions,  such  as  regulatory
requirements,  actuarially  determined  minimum  contribution  requirements  and  contributions  required  to  avoid  benefit  restrictions  for  the  defined  benefit
pension plans. For the year ended December 31, 2021, we contributed $10.3 million in cash to the defined benefit pension plans. We do not expect to make
any contributions to our defined benefit pension plans in 2022, and we do not expect to make any contributions to our other postretirement benefit plans in
2022. (See Note 9. Common Stock and Earnings Per Share and Note 11. Pension and Other Postretirement Benefit Plans.)

Liquidity and Capital Resources (Continued)

Contractual Obligations and Commercial Commitments. ALLETE has contractual obligations and other commitments that will need to be funded in the
future, in addition to its capital expenditure programs. Material contractual obligations and other commitments are as follows:

Long-Term Debt. ALLETE has material long-term debt obligations, including long-term debt due within one year. These obligations include the principal
amount of bonds, notes and loans which are recorded on the Consolidated Balance Sheet, plus interest. (See Note 7. Short-Term and Long‑Term Debt.)

Pension and Other Postretirement Benefit Plans. Pension and other postretirement benefit plan obligations include the current estimate of future benefit
payments.  Pension  contributions  are  dependent  on  several  factors  including  realized  asset  performance,  future  discount  rate  and  other  actuarial
assumptions,  Internal  Revenue  Service  and  other  regulatory  requirements,  and  contributions  required  to  avoid  benefit  restrictions  for  the  pension  plans.
Funding  for  the  other  postretirement  benefit  plans  is  impacted  by  realized  asset  performance,  future  discount  rate  and  other  actuarial  assumptions,  and
utility  regulatory  requirements.  Our  obligations  are  estimates  and  will  change  based  on  actual  market  performance,  changes  in  interest  rates  and  any
changes in governmental regulations. (See Note 11. Pension and Other Postretirement Benefit Plans.)

Operating Lease Obligations. ALLETE has certain operating lease obligations for the minimum payments required under various lease agreements which
are recorded on the Consolidated Balance Sheet. (See Note 1. Operations and Significant Accounting Policies.)

Easement Obligations. ALLETE has easement obligations for the minimum payments required under our land easement agreements at our wind energy
facilities. (See Note 8. Commitments, Guarantees and Contingencies.)

PPA  Obligations.  PPA  obligations  represent  our  Square  Butte,  Manitoba  Hydro  and  other  PPAs.  (See  Note  8.  Commitments,  Guarantees  and
Contingencies.)

Other Purchase Obligations. ALLETE has other purchase obligations covering our minimum purchase commitments under coal supply and rail contracts,
and long-term service agreements for wind energy facilities. (See Note 8. Commitments, Guarantees and Contingencies.)

Credit Ratings.  Access  to  reasonably  priced  capital  markets  is  dependent  in  part  on  credit  and  ratings.  Our  securities  have  been  rated  by  S&P  and  by
Moody’s. Rating agencies use both quantitative and qualitative measures in determining a company’s credit rating. These measures include business risk,
liquidity risk, competitive position, capital mix, financial condition, predictability of cash flows, management strength and future direction. Some of the
quantitative measures can be analyzed through a few key financial ratios, while the qualitative ones are more subjective. Our current credit ratings are listed
in the following table:

Common Stock Dividends.  ALLETE  is  committed  to  providing  a  competitive  dividend  to  its  shareholders  while  at  the  same  time  funding  its  growth.
ALLETE’s long-term objective is to maintain a dividend payout ratio similar to our peers and provide for future dividend increases. Our targeted payout
range  is  between  60  percent  and  70  percent.  In  2021,  we  paid  out  78  percent  (74  percent  in  2020;  65  percent  in  2019)  of  our  per  share  earnings  in
dividends. On February 3, 2022, our Board of Directors declared a dividend of $0.65 per share, which is payable on March 1, 2022, to shareholders of
record at the close of business on February 15, 2022.

(a) Capital expenditures in 2022 do not include costs related to ALLETE Clean Energy’s projects to repower and sell the 100 MW Northern Wind project or to develop and

sell the 92 MW Red Barn project as these projects will be sold upon completion. (See Outlook – ALLETE Clean Energy.)

(b) Our portion of estimated capital expenditures for construction of NTEC, an approximately 600 MW proposed combined-cycle natural gas-fired generating facility to be

built in Superior, Wisconsin, which will be jointly owned by Dairyland Power Cooperative, Basin and South Shore Energy.

We  are  well  positioned  to  meet  our  financing  needs  due  to  adequate  operating  cash  flows,  available  additional  working  capital  and  access  to  capital
markets. We will finance capital expenditures from a combination of internally generated funds, debt and equity issuance proceeds. We intend to maintain a
capital structure with capital ratios near current levels. (See Capital Structure.)

Environmental and Other Matters

Our businesses are subject to regulation of environmental matters by various federal, state and local authorities. A number of regulatory changes to the
Clean Air Act, the Clean Water Act and various waste management requirements have been promulgated by both the EPA and state authorities over the
past several years. Minnesota Power’s facilities are subject to additional requirements under many of these regulations. Minnesota Power is reshaping its
generation portfolio, over time, to reduce its reliance on coal, has installed cost-effective emission control technology, and advocates for sound science and
policy during rulemaking implementation. (See Note 8. Commitments, Guarantees and Contingencies.)

Market Risk

Securities Investments.

Available-for-Sale  Securities.  As  of  December  31,  2021,  our  available-for-sale  securities  portfolio  consisted  primarily  of  securities  held  in  other
postretirement plans to fund employee benefits.

INTEREST RATE RISK

We are exposed to risks resulting from changes in interest rates as a result of our issuance of variable rate debt. We manage our interest rate risk by varying
the issuance and maturity dates of our fixed rate debt, limiting the amount of variable rate debt, and continually monitoring the effects of market changes in
interest rates. We may also enter into derivative financial instruments, such as interest rate swaps, to mitigate interest rate exposure. The following table
presents the long-term debt obligations and the corresponding weighted average interest rate as of December 31, 2021:

Interest  rates  on  variable  rate  long-term  debt  are  reset  on  a  periodic  basis  reflecting  prevailing  market  conditions.  Based  on  the  variable  rate  debt
outstanding as of December 31, 2021, an increase of 100 basis points in interest rates would impact the amount of pre-tax interest expense by $3.0 million.
This amount was determined by considering the impact of a hypothetical 100 basis point increase to the average variable interest rate on the variable rate
debt outstanding as of December 31, 2021.

COMMODITY PRICE RISK

Our  regulated  utility  operations  incur  costs  for  power  and  fuel  (primarily  coal  and  related  transportation)  in  Minnesota,  and  power  and  natural  gas
purchased  for  resale  in  our  regulated  service  territory  in  Wisconsin.  Minnesota  Power’s  exposure  to  price  risk  for  these  commodities  is  significantly
mitigated by the current ratemaking process and regulatory framework, which allows recovery of fuel costs in excess of those included in base rates or
distribution  of  savings  in  fuel  costs  to  ratepayers.  SWL&P’s  exposure  to  price  risk  for  natural  gas  is  significantly  mitigated  by  the  current  ratemaking
process  and  regulatory  framework,  which  allows  the  commodity  cost  to  be  passed  through  to  customers.  We  seek  to  prudently  manage  our  customers’
exposure  to  price  risk  by  entering  into  contracts  of  various  durations  and  terms  for  the  purchase  of  power  and  coal  and  related  transportation  costs
(Minnesota Power) and natural gas (SWL&P).

POWER MARKETING

Minnesota Power’s power marketing activities consist of: (1) purchasing energy in the wholesale market to serve its regulated service territory when energy
requirements  exceed  generation  output;  and  (2)  selling  excess  available  energy  and  purchased  power.  From  time  to  time,  Minnesota  Power  may  have
excess  energy  that  is  temporarily  not  required  by  retail  and  municipal  customers  in  our  regulated  service  territory.  Minnesota  Power  actively  sells  any
excess energy to the wholesale market to optimize the value of its generating facilities.

We are exposed to credit risk primarily through our power marketing activities. We use credit policies to manage credit risk, which includes utilizing an
established credit approval process and monitoring counterparty limits.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act
Rule 13a-15(f) or 15d-15(f). Under the supervision and with the participation of our management, including our principal executive officer and principal
financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the Internal Control – Integrated
Framework  (framework)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.  Based  on  our  evaluation  under  the

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2021, has been audited by PricewaterhouseCoopers LLP,

Opinions on the Financial Statements and Internal Control over Financial Reporting

Report of Independent Registered Public Accounting Firm

We have audited the accompanying consolidated balance sheets of ALLETE, Inc. and its subsidiaries (the “Company”) as of December 31, 2021 and
December 31, 2020, and the related consolidated statements of income, of comprehensive income, of equity and of cash flows for each of the three years in
the period ended December 31, 2021, including the related notes and financial statement schedule listed in the index appearing under Item 15(a)(2)
(collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of
December 31, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations
of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of
December 31, 2021 and December 31, 2020, and the results of its operations and its cash flows for each of the three years in the period ended December
31, 2021 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all
material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control - Integrated
Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting,
and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial
Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's
internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight
Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable
assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective
internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial
statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis,
evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used
and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal
control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness
exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing
such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control
over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial
statements.

ALLETE, Inc. 2021 Form 10-K
66

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.

Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was
communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated
financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not
alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below,
providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Accounting for the Effects of Regulatory Matters

As described in Note 4 to the consolidated financial statements, the Company’s regulated utility operations are subject to accounting standards for the
effects of certain types of regulation. As of December 31, 2021, there was $512 million of regulatory assets and $545 million of regulatory liabilities
recorded. Regulatory assets represent incurred costs that have been deferred as they are probable for recovery in customer rates. Regulatory liabilities
represent obligations to make refunds to customers and amounts collected in rates for which the related costs have not yet been incurred. Management
assesses quarterly whether regulatory assets and liabilities meet the criteria for probability of future recovery or deferral. As disclosed by management,
these standards require the Company to reflect the effect of regulatory decisions in its financial statements. This assessment considers factors such as, but
not limited to, changes in the regulatory environment and recent rate orders to other regulated entities under the same jurisdiction. If future recovery or
refund of costs becomes no longer probable, the assets and liabilities would be recognized in current period net income or other comprehensive income.

The principal consideration for our determination that performing procedures relating to the Company’s accounting for the effects of regulatory matters is a
critical audit matter is the significant judgment by management in determining the recoverability of costs; this in turn led to a high degree of auditor
judgment, subjectivity and effort in performing procedures and evaluating audit evidence obtained related to the recoverability of costs.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated
financial statements. These procedures included testing the effectiveness of controls relating to management’s implementation of new regulatory orders,
changes to existing regulatory orders, and assessing the recoverability of costs. These procedures also included, among others, evaluating (i) the
reasonableness of management’s assessment of impacts arising from correspondence with regulators and changes in laws and regulations, (ii)
management’s judgments related to the recoverability of regulatory assets and the establishment of regulatory liabilities, and (iii) the sufficiency of the
disclosures in the consolidated financial statements. Testing the regulatory assets and liabilities involved considering the provisions and formulas outlined
in rate orders, other regulatory correspondence, and application of relevant regulatory precedents.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES

Financial Statement Preparation. References in this report to “we,” “us,” and “our” are to ALLETE and its subsidiaries, collectively. We prepare our
financial statements in conformity with GAAP. These principles require management to make informed judgments, best estimates, and assumptions that
affect the reported amounts of assets, liabilities, revenue and expenses. Actual results could differ from those estimates.

Subsequent Events. The Company performed an evaluation of subsequent events for potential recognition and disclosure through the time of the financial
statements issuance.

Principles of Consolidation. Our Consolidated Financial Statements include the accounts of ALLETE, all of our majority‑owned subsidiary companies
and variable interest entities of which ALLETE is the primary beneficiary. All material intercompany balances and transactions have been eliminated in
consolidation.

Variable Interest Entities. The  accounting  guidance  for  “Variable  Interest  Entities”  (VIE)  is  a  consolidation  model  that  considers  if  a  company  has  a
variable interest in a VIE. A VIE is a legal entity that possesses any of the following conditions: the entity’s equity at risk is not sufficient to permit the
legal entity to finance its activities without additional subordinated financial support, equity owners are unable to direct the activities that most significantly
impact the legal entity’s economic performance (or they possess disproportionate voting rights in relation to the economic interest in the legal entity), or the
equity owners lack the obligation to absorb the legal entity’s expected losses or the right to receive the legal entity’s expected residual returns. Entities are
required to consolidate a VIE when it is determined that they have a controlling financial interest in a VIE and therefore, are the primary beneficiary of that
VIE,  as  defined  by  the  accounting  guidance  for  “Variable  Interest  Entities.”  In  determining  whether  ALLETE  is  the  primary  beneficiary  of  a  VIE,
management considers whether ALLETE has the power to direct the most significant activities of the VIE and is obligated to absorb losses or receive the
expected residual returns that are significant to the VIE. The accounting guidance for VIEs applies to certain ALLETE Clean Energy wind energy facilities
and our investment in Nobles 2. (See Tax Equity Financing.)

Business Segments. We present three reportable segments: Regulated Operations, ALLETE Clean Energy and U.S. Water Services. Our segments were
determined  in  accordance  with  the  guidance  on  segment  reporting.  We  measure  performance  of  our  operations  through  budgeting  and  monitoring  of
contributions to consolidated net income by each business segment.

Regulated Operations  includes  our  regulated  utilities,  Minnesota  Power  and  SWL&P,  as  well  as  our  investment  in  ATC,  a  Wisconsin-based  regulated
utility  that  owns  and  maintains  electric  transmission  assets  in  portions  of  Wisconsin,  Michigan,  Minnesota  and  Illinois.  Minnesota  Power  provides
regulated  utility  electric  service  in  northeastern  Minnesota  to  approximately  150,000  retail  customers.  Minnesota  Power  also  has  15  non-affiliated
municipal  customers  in  Minnesota.  SWL&P  is  a  Wisconsin  utility  and  a  wholesale  customer  of  Minnesota  Power.  SWL&P  provides  regulated  utility
electric,  natural  gas  and  water  service  in  northwestern  Wisconsin  to  approximately  15,000  electric  customers,  13,000  natural  gas  customers  and
10,000  water  customers.  Our  regulated  utility  operations  include  retail  and  wholesale  activities  under  the  jurisdiction  of  state  and  federal  regulatory
authorities.

ALLETE Clean Energy focuses on developing, acquiring, and operating clean and renewable energy projects. ALLETE Clean Energy currently owns and
operates,  in  seven  states,  more  than  1,300  MW  of  nameplate  capacity  wind  energy  generation  that  is  contracted  under  PSAs  of  various  durations.  In
addition, ALLETE Clean Energy currently has approximately 200 MW of wind energy facilities under contract for sale to others. ALLETE Clean Energy
also engages in the development of wind energy facilities to operate under long-term PSAs or for sale to others upon completion.

U.S.  Water  Services  provided  integrated  water  management  for  industry  by  combining  chemical,  equipment,  engineering  and  service  for  customized
solutions to reduce water and energy usage, and improve efficiency. In March 2019, the Company sold U.S. Water Services to a subsidiary of Kurita Water
Industries Ltd. pursuant to a stock purchase agreement for approximately $270 million in cash, net of transaction costs and cash retained.

ALLETE, Inc. 2021 Form 10-K

NOTE 1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued)

Corporate and Other is comprised of BNI Energy, our investment in Nobles 2, South Shore Energy, ALLETE Properties, other business development and
corporate  expenditures,  unallocated  interest  expense,  a  small  amount  of  non-rate  base  generation,  approximately  4,000  acres  of  land  in  Minnesota,  and
earnings on cash and investments.

BNI Energy mines and sells lignite coal to two North Dakota mine-mouth generating units, one of which is Square Butte. In 2021, Square Butte supplied
50 percent (227.5 MW) of its output to Minnesota Power under long-term contracts. (See Note 8. Commitments, Guarantees and Contingencies.)

Our  investment  in  Nobles  2  represents  a  49  percent  equity  interest  in  Nobles  2,  the  entity  that  owns  and  operates  a  250  MW  wind  energy  facility  in
southwestern Minnesota pursuant to a 20-year PPA with Minnesota Power.

South  Shore  Energy,  ALLETE’s  non-rate  regulated,  Wisconsin  subsidiary,  is  developing  NTEC,  an  approximately  600  MW  proposed  combined-cycle
natural  gas-fired  generating  facility  to  be  built  in  Superior,  Wisconsin,  which  will  be  jointly  owned  by  Dairyland  Power  Cooperative,  Basin  and  South
Shore Energy. Minnesota Power is expected to purchase approximately 20 percent of the facility's output starting in 2025 pursuant to a capacity dedication
agreement. Construction of NTEC is subject to obtaining additional permits from local, state and federal authorities. The total project cost is estimated to
be approximately $700 million, of which South Shore Energy’s portion is expected to be approximately $150 million. South Shore Energy’s portion of
NTEC project costs incurred through December 31, 2021, is approximately $5 million.

On  October  1,  2021,  South  Shore  Energy  sold  a  portion  of  its  undivided  ownership  interest  in  NTEC  for  approximately  $20  million  representing
reimbursement of current costs plus a fee for prior development costs and risks incurred. Following the transaction, South Shore Energy now owns a 20
percent  undivided  ownership  interest  in  NTEC,  Basin  owns  a  30  percent  undivided  ownership  interest  in  NTEC  and  Dairyland  Power  Cooperative
continues  to  own  a  50  percent  undivided  ownership  interest  in  NTEC.  The  closing  of  the  transaction  resulted  in  the  recognition  of  an  approximately
$8.5 million after-tax gain recorded in Corporate and Other in the fourth quarter of 2021, related to prior development costs and risks incurred.

ALLETE  Properties  represents  our  legacy  Florida  real  estate  investment.  Our  strategy  incorporates  the  possibility  of  a  bulk  sale  of  the  entire  ALLETE
Properties portfolio. Proceeds from a bulk sale would be strategically deployed to support growth at our Regulated Operations and ALLETE Clean Energy.
ALLETE Properties continues to pursue sales of individual parcels over time and will continue to maintain key entitlements and infrastructure.

Cash,  Cash  Equivalents  and  Restricted  Cash.  We  consider  all  investments  purchased  with  original  maturities  of  three  months  or  less  to  be  cash
equivalents. As of December 31, 2021, and 2020, restricted cash amounts included in Prepayments and Other on the Consolidated Balance Sheet include
collateral deposits required under an ALLETE Clean Energy loan agreement. The December 31, 2019 amount also includes deposits required under tax
equity financing agreements. The restricted cash amounts included in Other Non-Current Assets represent collateral deposits required under an ALLETE
Clean Energy loan agreement and PSAs. The December 31, 2020 and 2019 amounts also include deposits required under tax equity financing agreements.
The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the Consolidated Balance Sheet that aggregate to
the amounts presented in the Consolidated Statement of Cash Flows.

Accounts Receivable. Accounts receivable are reported on the Consolidated Balance Sheet net of an allowance for doubtful accounts. The allowance is
based on our evaluation of the receivable portfolio under current conditions, overall portfolio quality, review of specific situations and such other factors
that, in our judgment, deserve recognition in estimating losses.

Concentration of Credit Risk. We are subject to concentration of credit risk primarily as a result of accounts receivable. Minnesota Power sells electricity
to eight Large Power Customers. Receivables from these customers totaled $7.8 million as of December 31, 2021 ($10.3 million as of December 31, 2020).
Minnesota  Power  does  not  obtain  collateral  to  support  utility  receivables,  but  monitors  the  credit  standing  of  major  customers.  In  addition,  Minnesota
Power, as permitted by the MPUC, requires its taconite-producing Large Power Customers to pay weekly for electric usage based on monthly energy usage
estimates, which allows us to closely manage collection of amounts due. Minnesota Power’s taconite customers, which are currently owned by two entities
at  the  end  of  2021,  accounted  for  approximately  32  percent  of  Regulated  Operations  operating  revenue  and  approximately  28  percent  of  consolidated
operating revenue in 2021 (29 percent of Regulated Operations operating revenue and 25 percent of consolidated operating revenue in 2020). In 2019, a
single entity accounted for approximately 14 percent of Regulated Operations operating revenue and 12 percent of consolidated operating revenue.

Long-Term Finance Receivables. Long-term finance receivables relating to our real estate operations are collateralized by property sold, accrue interest at
market-based  rates  and  are  net  of  an  allowance  for  doubtful  accounts.  We  assess  delinquent  finance  receivables  by  comparing  the  balance  of  such
receivables to the estimated fair value of the collateralized property. If the fair value of the property is less than the finance receivable, we record a reserve
for the difference. We estimate fair value based on recent property tax assessed values or current appraisals.

Available-for-Sale Securities.  Available-for-sale  debt  and  equity  securities  are  recorded  at  fair  value.  Unrealized  gains  and  losses  on  available-for-sale
debt  securities  are  included  in  accumulated  other  comprehensive  income  (loss),  net  of  tax.  Unrealized  gains  and  losses  on  available-for-sale  equity
securities are recognized in earnings. We use the specific identification method as the basis for determining the cost of securities sold.

Inventories – Net. Inventories are stated at the lower of cost or net realizable value. Inventories in our Regulated Operations segment are carried at an
average cost or first-in, first-out basis. Inventories in our ALLETE Clean Energy segment and Corporate and Other businesses are carried at an average
cost, first-in, first-out or specific identification basis.

Current Liabilities.)

Property, Plant and Equipment. Property, plant and equipment are recorded at original cost and are reported on the Consolidated Balance Sheet net of
accumulated depreciation. Expenditures for additions, significant replacements, improvements and major plant overhauls are capitalized; maintenance and
repair costs are expensed as incurred. Gains or losses on property, plant and equipment for Corporate and Other operations are recognized when they are
retired  or  otherwise  disposed.  When  property,  plant  and  equipment  in  our  Regulated  Operations  and  ALLETE  Clean  Energy  segments  are  retired  or
otherwise disposed, no gain or loss is recognized in accordance with the accounting standards for component depreciation except for certain circumstances
where the retirement is unforeseen or unexpected. Our Regulated Operations capitalize AFUDC, which includes both an interest and equity component.
AFUDC represents the cost of both debt and equity funds used to finance utility plant additions during construction periods. AFUDC amounts capitalized
are included in rate base and are recovered from customers as the related property is depreciated. Upon MPUC approval of cost recovery, the recognition of
AFUDC ceases. (See Note 2. Property, Plant and Equipment.)

We  believe  that  long-standing  ratemaking  practices  approved  by  applicable  state  and  federal  regulatory  commissions  allow  for  the  recovery  of  the
remaining  book  value  of  retired  plant  assets.  Minnesota  Power’s  2015  IRP  contained  steps  in  Minnesota  Power’s  EnergyForward  plan  including  the
economic idling of Taconite Harbor Units 1 and 2 in 2016, and the ceasing of coal-fired operations at Taconite Harbor in 2020. As of December 31, 2021,
Taconite Harbor had a net book value of approximately $45 million. The MPUC order for the 2015 IRP also directed Minnesota Power to retire Boswell
Units 1 and 2, which occurred in the fourth quarter of 2018. As part of the 2016 general retail rate case, the MPUC allowed recovery of the remaining book
value of Boswell Units 1 and 2 through 2022. In its latest IRP filing, Minnesota Power proposed retiring Boswell Unit 3 by 2030 and transforming Boswell
Unit  4  to  be  coal-free  by  2035.  Boswell  Unit  3  and  Unit  4  have  a  net  book  value  of  approximately  $245  million  and  $435  million,  respectively,  as  of
December 31, 2021. (See Note 4. Regulatory Matters.) We do not expect to record any impairment charge as a result of these operating changes at Taconite
Harbor and Boswell. In addition, we expect to be able to continue depreciating these assets for at least their established remaining useful lives; however, we
are unable to predict the impact of regulatory outcomes resulting in changes to their established remaining useful lives.

Impairment  of  Long-Lived  Assets.  We  review  our  long-lived  assets  for  indicators  of  impairment  in  accordance  with  the  accounting  standards  for
property,  plant  and  equipment  on  a  quarterly  basis.  This  includes  our  property,  plant  and  equipment  (see  Property,  Plant  and  Equipment)  and  land
inventory.  Land  inventory  is  accounted  for  as  held  for  use  and  is  recorded  at  cost,  unless  the  carrying  value  is  determined  not  to  be  recoverable  in
accordance with the accounting standards for property, plant and equipment, in which case the land inventory is written down to estimated fair value.

In  accordance  with  the  accounting  standards  for  property,  plant  and  equipment,  if  indicators  of  impairment  exist,  we  test  our  long‑lived  assets  for
recoverability by comparing the carrying amount of the asset to the undiscounted future net cash flows expected to be generated by the asset. Cash flows
are assessed at the lowest level of identifiable cash flows. The undiscounted future net cash flows are impacted by trends and factors known to us at the
time they are calculated and our expectations related to: management’s best estimate of future use; sales prices; holding period and timing of sales; method
of disposition; and future expenditures necessary to maintain the operations.

We continue to monitor changes in the broader energy markets along with wind resource expectations that could indicate impairment at ALLETE Clean
Energy wind energy facilities upon contract expirations. A continued decline in energy prices or lower wind resource expectations could result in a future
impairment.

In 2021, 2020, and 2019, there were no indicators of impairment for our property, plant, and equipment or land inventory. As a result, no impairment was
recorded in 2021, 2020 or 2019.

Derivatives.  ALLETE  is  exposed  to  certain  risks  relating  to  its  business  operations  that  can  be  managed  through  the  use  of  derivative  instruments.
ALLETE may enter into derivative instruments to manage those risks including interest rate risk related to certain variable-rate borrowings and commodity
price  risk  related  to  sales  to  retail  and  municipal  customers  as  well  as  other  power  suppliers.  We  have  determined  that  either  these  agreements  are  not
derivatives,  or,  if  they  are  derivatives,  the  agreements  qualify  for  the  normal  purchases  and  normal  sales  exception  to  derivative  accounting  guidance;
therefore, derivative accounting is not required.

Accounting for Stock-Based Compensation. We apply the fair value recognition guidance for share-based payments. Under this guidance, we recognize
stock-based compensation expense for all share-based payments granted, net of an estimated forfeiture rate. (See Note 12. Employee Stock and Incentive
Plans.)

Leases.

We determine if a contract is, or contains, a lease at inception and recognize a right-of-use asset and lease liability for all leases with a term greater than 12
months. Our right-of-use assets and lease liabilities for operating leases are included in Other Non-Current Assets, Other Current Liabilities and Other Non-
Current Liabilities, respectively, in our Consolidated Balance Sheet. We currently do not have any finance leases.

Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments
arising from the lease. Operating lease right-of-use assets and lease liabilities are recognized at the commencement date based on the estimated present
value of lease payments over the lease term. As our leases do not provide an explicit rate, we determine the present value of future lease payments based on
our estimated incremental borrowing rate using information available at the lease commencement date. The operating lease right-of-use asset includes lease
payments to be made during the lease term and any lease incentives, as applicable.

Our leases may include options to extend or buy out the lease at certain points throughout the term, and if it is reasonably certain at lease commencement
that we will exercise that option, we include those rental payments in our calculation of the right-of-use asset and lease liability. Lease and rent expense is
recognized on a straight-line basis over the lease term. Leases with a term of 12 months or less are not recognized on the Consolidated Balance Sheet.

The majority of our operating leases are for heavy equipment, vehicles and land with fixed monthly payments which we group into two categories: Vehicles
and Equipment; and Land and Other. Our largest operating lease is for the dragline at BNI Energy which includes a termination payment at the end of the
lease term if we do not exercise our purchase option. The amount of this payment is $3 million and is included in our calculation of the right-of-use asset
and lease liability recorded. None of our other leases contain residual value guarantees.

Environmental Liabilities. 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. Accruals are
adjusted  as  assessment  and  remediation  efforts  progress,  or  as  additional  technical  or  legal  information  becomes  available.  Accruals  for  environmental
liabilities are included in the Consolidated 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 expensed unless recoverable in rates from customers. (See Note 8. Commitments,
Guarantees and Contingencies.)

Revenue.

Contracts  with  Customers  –  Utility  includes  sales  from  our  regulated  operations  for  generation,  transmission  and  distribution  of  electric  service,  and
distribution of water and gas services to our customers. Also included is an immaterial amount of regulated steam generation that is used by customers in
the production of paper and pulp.

Contracts  with  Customers  – Non-utility  includes  sales  of  goods  and  services  to  customers  from  ALLETE  Clean  Energy,  U.S.  Water  Services  and  our
Corporate and Other businesses.

Other –  Non-utility  is  the  non-cash  adjustments  to  revenue  recognized  by  ALLETE  Clean  Energy  for  the  amortization  of  differences  between  contract
prices and estimated market prices for PSAs that were assumed during the acquisition of various wind energy facilities.

Revenue  Recognition.  Revenue  is  recognized  upon  transfer  of  control  of  promised  goods  or  services  to  our  customers  in  an  amount  that  reflects  the
consideration we expect to receive in exchange for those products or services. Revenue is recognized net of allowance for returns and any taxes collected
from customers, which are subsequently remitted to the appropriate governmental authorities. We account for shipping and handling activities that occur
after the customer obtains control of goods as a cost rather than an additional performance obligation thereby recognizing revenue at time of shipment and
accruing  shipping  and  handling  costs  when  control  transfers  to  our  customers.  We  have  a  right  to  consideration  from  our  customers  in  an  amount  that
corresponds directly with the value to the customer for our performance completed to date; therefore, we may recognize revenue in the amount to which we
have a right to invoice.

Nature of Revenue Streams

Utility

Residential and Commercial includes sales for electric, gas or water service to customers, who have implied contracts with the utility, under rates governed
by the MPUC, PSCW or FERC. Customers are billed on a monthly cycle basis and revenue is recognized for electric, gas or water service delivered during
the billing period. Revenue is accrued for service provided but not yet billed at period end. Performance obligations with these customers are satisfied at
time of delivery to customer meters and simultaneously consumed.

Municipal  includes  sales  to  15  non-affiliated  municipal  customers  in  Minnesota  under  long-term  wholesale  electric  contracts.  All  wholesale  electric
contracts  include  a  termination  clause  requiring  a  three-year  notice  to  terminate.  These  contracts  have  termination  dates  ranging  through  2037,  with  a
majority of contracts effective through 2029. Performance obligations with these customers are satisfied at the time energy is delivered to an agreed upon
municipal substation or meter.

Industrial includes sales recognized from contracts with customers in the taconite mining, paper, pulp and secondary wood products, pipeline and other
industries.  Industrial  sales  accounted  for  approximately  47  percent  of  total  regulated  utility  kWh  sales  for  the  year  ended  December  31,  2021.  Within
industrial  revenue,  Minnesota  Power  had  eight  Large  Power  Customer  contracts,  each  serving  requirements  of  10  MW  or  more  of  customer  load  as  of
December 31, 2021. These contracts automatically renew past the contract term unless a four-year advanced written notice is given. Large Power Customer
contracts  have  earliest  termination  dates  ranging  from  2025  through  2029.  In  January  2021,  Verso  Corporation  provided  notice  of  termination  for  its
contract. Minnesota Power and Verso Corporation mutually agreed to resolve the outstanding commitments under the contract in January 2022. We satisfy
our  performance  obligations  for  these  customers  at  the  time  energy  is  delivered  to  an  agreed  upon  customer  substation.  Revenue  is  accrued  for  energy
provided  but  not  yet  billed  at  period  end.  Based  on  current  contracts  with  industrial  customers,  we  expect  to  recognize  minimum  revenue  for  the  fixed
contract components of approximately $50 million per annum through 2025, $15 million in 2026, and $30 million in total thereafter, which reflects the
termination  notice  period  in  these  contracts.  When  determining  minimum  revenue,  we  assume  that  customer  contracts  will  continue  under  the  contract
renewal provision; however, if long-term contracts are renegotiated and subsequently approved by the MPUC or there are changes within our industrial
customer  class,  these  amounts  may  be  impacted.  Contracts  with  customers  that  contain  variable  pricing  or  quantity  components  are  excluded  from  the
expected minimum revenue amounts.

Other Power Suppliers includes the sale of energy under a long-term PSA with one customer as well as MISO market and liquidation sales. The expiration
date  of  this  PSA  is  2028.  Performance  obligations  with  these  customers  are  satisfied  at  the  time  energy  is  delivered  to  an  agreed  upon  delivery  point
defined in the contract (generally the MISO pricing node). The current contract with one customer contains variable pricing components that prevent us
from estimating future minimum revenue.

Other Revenue includes all remaining individually immaterial revenue streams for Minnesota Power and SWL&P, and is comprised of steam sales to paper
and pulp mills, wheeling revenue and other sources. Revenue for steam sales to customers is recognized at the time steam is delivered and simultaneously
consumed. Revenue is recognized at the time each performance obligation is satisfied.

CIP Financial Incentive reflects certain revenue that is a result of the achievement of certain objectives for our CIP financial incentives. This revenue is
accounted for in accordance with the accounting standards for alternative revenue programs which allow for the recognition of revenue under an alternative
revenue program if the program is established by an order from the utility’s regulatory commission, the order allows for automatic adjustment of future
rates, the amount of revenue recognized is objectively determinable and probable of recovery, and the revenue will be collected within 24 months following
the end of the annual period in which it is recognized. CIP financial incentives are recognized in the period in which the MPUC approves the filing, which
is typically mid-year.

NOTE 1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued)
Revenue (Continued)

Non-utility

ALLETE Clean Energy

Long-term PSA  revenue  includes  all  sales  recognized  under  long-term  contracts  for  production,  curtailment,  capacity  and  associated  renewable  energy
credits from ALLETE Clean Energy wind energy facilities. Expiration dates of these PSAs range from 2022 through 2039. Performance obligations for
these contracts are satisfied at the time energy is delivered to an agreed upon point, or production is curtailed at the request of the customer, at specified
prices. Revenue from the sale of renewable energy credits is recognized at the same time the related energy is delivered to the customer when sold to the
same party.

Sale  of  Wind  Energy  Facility  includes  revenue  recognized  for  the  design,  development,  construction,  and  sale  of  a  wind  energy  facility  to  a  customer.
Performance  obligations  for  these  types  of  agreements  are  satisfied  at  the  time  the  completed  project  is  transferred  to  the  customer  at  the  commercial
operation date. Revenue from the sale of a wind energy facility is recognized at the time of asset transfer.

Other  is  the  non-cash  adjustments  to  revenue  recognized  by  ALLETE  Clean  Energy  for  the  amortization  of  differences  between  contract  prices  and
estimated market prices on assumed PSAs. As part of wind energy facility acquisitions, ALLETE Clean Energy assumed various PSAs that were above or
below estimated market prices at the time of acquisition; the resulting differences between contract prices and estimated market prices are amortized to
revenue over the remaining PSA term.

U.S. Water Services

In 2019, ALLETE completed the sale of U.S. Water Services. Prior to the sale, ALLETE recognized revenue under the point-in-time, contract and capital
project streams. Point-in-time revenue was recognized for purchases by customers for chemicals, consumable equipment or related maintenance and repair
services  as  the  customer’s  usage  and  needs  changed  over  time.  Contract  revenue  included  monthly  revenue  from  contracts  with  customers  to  provide
chemicals, consumable equipment and services to meet customer needs during the contract period at a fixed monthly price. Capital Project revenue was
recognized at the time of sale when equipment and other components were assembled to create a water treatment system for a customer.

Corporate and Other

Long-term Contract encompasses the sale and delivery of coal to customer generation facilities. Revenue is recognized on a monthly basis at the cost of
production  plus  a  specified  profit  per  ton  of  coal  delivered  to  the  customer.  Coal  sales  are  secured  under  long-term  coal  supply  agreements  extending
through 2037. Performance obligations are satisfied during the period as coal is delivered to customer generation facilities.

Other primarily includes revenue from BNI Energy unrelated to coal, the sale of real estate from ALLETE Properties, and non‑rate base steam generation
that is sold for use during production of paper and pulp. Performance obligations are satisfied when control transfers to the customer.

Payment Terms

Payment  terms  and  conditions  vary  across  our  businesses.  Aside  from  taconite-producing  Large  Power  Customers,  payment  terms  generally  require
payment to be made within 15 to 30 days from the end of the period that the service has been rendered. In the case of its taconite-producing Large Power
Customers, as permitted by the MPUC, Minnesota Power requires weekly payments for electric usage based on monthly energy usage estimates. These
customers receive estimated bills based on Minnesota Power’s estimate of the customers’ energy usage, forecasted energy prices and fuel adjustment clause
estimates. Minnesota Power’s taconite-producing Large Power Customers have generally predictable energy usage on a weekly basis and any differences
that occur are trued-up the following month. Due to the timing difference of revenue recognition from the timing of invoicing and payment, the taconite-
producing Large Power Customers receive credit for the time value of money; however, we have determined that our contracts do not include a significant
financing component as the period between when we transfer the service to the customer and when they pay for such service is minimal.

Revenue (Continued)

Assets Recognized From the Costs to Obtain a Contract with a Customer

We recognize as an asset the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to be longer than one year. We
expense  incremental  costs  when  the  asset  that  would  have  resulted  from  capitalizing  these  costs  would  have  been  amortized  in  one  year  or  less.  As  of
December 31, 2021, we have $23.3 million of assets recognized for costs incurred to obtain contracts with our customers ($25.5 million as of December 31,
2020). Management determined the amount of costs to be recognized as assets based on actual costs incurred and paid to obtain and fulfill these contracts
to provide goods and services to our customers. Assets recognized to obtain contracts are amortized on a straight-line basis over the contract term as a non-
cash  reduction  to  revenue.  We  recognized  $2.7  million  of  non-cash  amortization  for  the  year  ended  December  31,  2021  ($2.6  million  for  the  year  end
December 31, 2020).

Unamortized Discount and Premium on Debt. Discount and premium on debt are deferred and amortized over the terms of the related debt instruments
using a method which approximates the effective interest method.

Tax Equity Financings. Certain subsidiaries of ALLETE have entered into tax equity financings that include forming limited liability companies (LLC)
with third-party investors for certain wind projects. Tax equity financings have specific terms that dictate distributions of cash and the allocation of tax
attributes among the LLC members, who are divided into two categories: the sponsor and third-party investors. ALLETE subsidiaries are the sponsors in
these tax equity financings. The distributions of cash and allocation of tax attributes in these financings generally differ from the underlying percentage
ownership  interests  in  the  related  LLC,  with  a  disproportionate  share  of  tax  attributes  (including  accelerated  depreciation  and  production  tax  credits)
allocated to third-party investors in order to achieve targeted after-tax rates of return, or target yield, from project operations, and a disproportionate share
of cash distributions made to the sponsor.

The target yield and other terms vary by tax equity financing. Once the target yield has been achieved, a “flip point” is recognized. In addition, tax equity
financings  typically  provide  that  cash  distributions  can  be  temporarily  increased  to  the  third-party  investors  in  order  to  meet  cumulative  distribution
thresholds. After the flip point, tax attributes and cash distributions are both typically disproportionately allocated to the sponsor.

Tax  equity  financings  include  affirmative  and  negative  covenants  that  are  similar  to  what  a  project  lender  would  require  in  a  project  financing,  such  as
financial  reporting,  insurance,  maintenance  and  prudent  operator  standards.  Most  covenants  are  no  longer  applicable  once  the  flip  point  occurs  and  any
other obligations of the third-party investor have been eliminated.

The  third-party  investors’  portions  of  equity  ownership  in  tax  equity  LLCs  are  recorded  as  non-controlling  interest  in  subsidiaries  on  the  Consolidated
Balance Sheet and earnings allocated to third-party investors are recorded as net loss attributable to non-controlling interest on the Consolidated Statement
of Income.

Non-Controlling  Interest  in  Subsidiaries.  Non-controlling  interest  in  subsidiaries  represents  the  portion  of  equity  ownership,  net  income  (loss),  and
comprehensive income (loss) in subsidiaries that is not attributable to equity holders of ALLETE. These amounts as of and for the years ended December
31, 2021 and 2020, related to the tax equity financings for ALLETE Clean Energy’s 106 MW Glen Ullin, 80 MW South Peak, 303 MW Diamond Spring
and 303 MW Caddo wind energy facilities as well as ALLETE’s equity investment in the 250 MW Nobles 2 wind energy facility.

For those wind projects with tax equity financings where the economic benefits are not allocated based on the underlying ownership percentage interests,
we have determined that the appropriate methodology for calculating the non-controlling interest in subsidiaries balance is the hypothetical liquidation at
book  value  (HLBV)  method.  The  HLBV  method  is  a  balance  sheet  approach  which  reflects  the  substantive  economic  arrangements  in  the  tax  equity
financing structures.

ALLETE, Inc. 2021 Form 10-K
82

NOTE 1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued)
Non-Controlling Interest in Subsidiaries (Continued)

Under the HLBV method, amounts reported as non-controlling interest in subsidiaries on the Consolidated Balance Sheet represent the amounts the third-
party investors would hypothetically receive at each balance sheet reporting date under the liquidation provisions of the LLC agreements, assuming the net
assets of the wind projects were liquidated at amounts determined in accordance with GAAP and distributed to the third-party investor and sponsor. The
resulting non-controlling interest in subsidiaries balance in these projects is reported as a component of equity on the Consolidated Balance Sheet.

The  results  of  operations  for  these  projects  attributable  to  non-controlling  interest  under  the  HLBV  method  is  determined  as  the  difference  in  non-
controlling interest in subsidiaries on the Consolidated Balance Sheet at the start and end of each reporting period, after taking into account any capital
transactions between the projects and the third-party investors.

Factors  used  in  the  HLBV  calculation  include  GAAP  income,  taxable  income  (loss),  tax  attributes  such  as  accelerated  depreciation  and  production  tax
credits, capital contributions, cash distributions, and the target yield specified in the corresponding LLC agreement. Changes in these factors could have a
significant impact on the amounts that third-party investors and sponsors would receive upon a hypothetical liquidation. The use of the HLBV method to
allocate income to the non-controlling interest in subsidiaries may create variability in our results of operations as the application of the HLBV method can
drive variability in net income or loss attributable to non-controlling interest in subsidiaries from period to period.

Income Taxes. ALLETE and its subsidiaries file a consolidated federal income tax return as well as combined and separate state income tax returns. We
account for income taxes using the liability method in accordance with GAAP for income taxes. Under the liability method, deferred income tax assets and
liabilities are established for all temporary differences in the book and tax basis of assets and liabilities, based upon enacted tax laws and rates applicable to
the periods in which the taxes become payable.

Due to the effects of regulation on Minnesota Power and SWL&P, certain adjustments made to deferred income taxes are, in turn, recorded as regulatory
assets or liabilities. Federal investment tax credits have been recorded as deferred credits and are being amortized to income tax expense over the service
lives of the related property. In accordance with GAAP for uncertainty in income taxes, we are required to recognize in our 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 more than 50 percent likely. (See Note 10. Income Tax Expense.)

Excise Taxes. We collect excise taxes from our customers levied by governmental entities. These taxes are stated separately on the billing to the customer
and recorded as a liability to be remitted to the governmental entity. We account for the collection and payment of these taxes on a net basis.

Asset Retirement Obligations. We recognize, at fair value, obligations associated with the retirement of certain tangible, long‑lived assets that result from
the acquisition, construction, development or normal operation of the asset. Asset retirement obligations (AROs) relate primarily to the decommissioning
of our coal-fired and wind energy facilities, and land reclamation at BNI Energy. AROs are included in Other Non-Current Liabilities on the Consolidated
Balance  Sheet.  The  associated  retirement  costs  are  capitalized  as  part  of  the  related  long-lived  asset  and  depreciated  over  the  useful  life  of  the  asset.
Removal costs associated with certain distribution and transmission assets have not been recognized, as these facilities have indeterminate useful lives.

Conditional  asset  retirement  obligations  have  been  identified  for  treated  wood  poles  and  remaining  polychlorinated  biphenyl  and  asbestos-containing
assets; however, the period of remediation is indeterminable and removal liabilities have not been recognized.

Long-standing ratemaking practices approved by applicable state and federal regulatory authorities have allowed provisions for future plant removal costs
in  depreciation  rates.  These  plant  removal  cost  recoveries  are  classified  either  as  AROs  or  as  a  regulatory  liability  for  non-AROs.  To  the  extent  annual
accruals for plant removal costs differ from accruals under approved depreciation rates, a regulatory asset has been established in accordance with GAAP
for AROs. (See Note 4. Regulatory Matters.)

NOTE 3. JOINTLY-OWNED FACILITIES AND ASSETS

Boswell Unit 4. Minnesota Power owns 80 percent of the 585 MW Boswell Unit 4. While Minnesota Power operates the plant, certain decisions about the
operations of Boswell Unit 4 are subject to the oversight of a committee on which it and WPPI Energy, the owner of the remaining 20 percent, have equal
representation and voting rights. Each owner must provide its own financing and is obligated to its ownership share of operating costs. Minnesota Power’s
share of operating expenses for Boswell Unit 4 is included in Operating Expenses on the Consolidated Statement of Income.

Electric Rates. Entities within our Regulated Operations segment file for periodic rate revisions with the MPUC, PSCW or FERC. As authorized by the
MPUC, Minnesota Power also recognizes revenue under cost recovery riders for transmission, renewable and environmental investments and expenditures.
(See Transmission  Cost  Recovery  Rider,  Renewable  Cost  Recovery  Rider,  Solar  Cost  Recovery  Rider  and  Environmental  Improvement  Rider.) Revenue
from cost recovery riders was $38.9 million in 2021 ($29.9 million in 2020; $31.8 million in 2019).

2020 Minnesota General Rate Case. In November 2019, Minnesota Power filed a retail rate increase request with the MPUC seeking an average increase
of  approximately  10.6  percent  for  retail  customers.  The  rate  filing  sought  a  return  on  equity  of  10.05  percent  and  a  53.81  percent  equity  ratio.  On  an
annualized basis, the requested final rate increase would have generated approximately $66 million in additional revenue. In December 2019 orders, the
MPUC accepted the filing as complete and authorized an annual interim rate increase of $36.1 million beginning January 1, 2020.

In April 2020, Minnesota Power filed a request with the MPUC that proposed a resolution of Minnesota Power’s 2020 general rate case. Key components
of our proposal included removing the power marketing margin credit in base rates and reflecting actual power marketing margins in the fuel adjustment
clause effective May 1, 2020; refunding to customers interim rates collected through April 2020; increasing customer rates 4.1 percent compared to the 5.8
percent increase reflected in interim rates; and a provision that Minnesota Power would not file another rate case until at least November 1, 2021, unless
certain events occur. In a June 2020 order, the MPUC approved Minnesota Power’s petition and proposal to resolve and withdraw the general rate case.
Effective May 1, 2020, customer rates were set at an increase of 4.1 percent with the removal of the power marketing margin credit from base rates. Actual
power marketing margins will be reflected in the fuel adjustment clause. Reserves for interim rates of $11.7 million were recorded in the second quarter of
2020 and refunded in the third and fourth quarters of 2020.

2022  Minnesota  General  Rate  Case.  On  November  1,  2021,  Minnesota  Power  filed  a  retail  rate  increase  request  with  the  MPUC  seeking  an  average
increase of approximately 18 percent for retail customers. The rate filing seeks a return on equity of 10.25 percent and a 53.81 percent equity ratio. On an
annualized basis, the requested final rate increase would generate approximately $108 million in additional revenue. In orders dated December 30, 2021,
the  MPUC  accepted  the  filing  as  complete  and  authorized  an  annual  interim  rate  increase  beginning  January  1,  2022,  with  approximately  $80  million
expected to be collected in cash and approximately $8 million of interim rates for residential customers deferred with a final determination on recovery at
the end of the rate case.

Minnesota Power Land Sales. In August 2020, Minnesota Power filed a petition with the MPUC for approval to sell land that surrounds several reservoirs
on  its  hydroelectric  system  and  is  no  longer  required  to  maintain  its  operations.  The  land  has  an  estimated  value  of  approximately  $100  million,  and
Minnesota Power proposed to credit ratepayers the net proceeds from the sales in a future rate case or through its renewable resources rider to mitigate
future rate increases. In an order dated November 18, 2021, the MPUC authorized the land sales and directed the net proceeds to be refunded to ratepayers
subject to certain conditions and required compliance filings.

FERC-Approved Wholesale Rates. Minnesota Power has wholesale contracts with 15 non-affiliated municipal customers in Minnesota and SWL&P. Three
of the wholesale contracts include a termination clause requiring a three-year notice to terminate.

Minnesota  Power’s  wholesale  electric  contract  with  the  Nashwauk  Public  Utilities  Commission  was  extended  in  October  2020  and  is  effective  through
December 31, 2037. The wholesale electric service contract with SWL&P is effective through February 28, 2025. Under the agreement with SWL&P, no
termination  notice  has  been  given.  The  rates  included  in  these  two  contracts  are  set  each  July  1  based  on  a  cost-based  formula  methodology,  using
estimated costs and a rate of return that is equal to Minnesota Power’s authorized rate of return for Minnesota retail customers. The formula-based rate
methodology also provides for a yearly true-up calculation for actual costs incurred.

Minnesota Power’s wholesale electric contracts with 13 other municipal customers were extended in January 2022 and are effective through 2029. These
contracts are based on fixed prices for capacity and energy. The base energy charge for each year is adjusted annually for updated fuel and purchased power
costs. The wholesale electric contract with one other municipal customer is effective through 2024. The capacity charge is determined using a cost-based
formula methodology with limits on the annual change from the previous year’s capacity charge. The base energy charge for each year of the contract term
is set each January 1, subject to monthly adjustment, and is determined using a cost-based formula methodology.

Transmission Cost Recovery Rider. Minnesota Power has an approved cost recovery rider in place to charge retail customers on a current basis for certain
transmission investments and expenditures, including a return on the capital invested. Current customer billing rates are based on a December 2020 order.
In  December  2020,  Minnesota  Power  filed  a  petition  seeking  MPUC  approval  to  update  customer  billing  rates  for  additional  investments  made  for  the
GNTL. On December 28, 2021, Minnesota Power submitted its annual factor filing seeking MPUC approval to further update customer billing rates under
the transmission cost recovery rider.

Renewable Cost Recovery Rider. Minnesota Power has an approved cost recovery rider in place to charge retail customers on a current basis for the costs of
certain renewable investments and expenditures, including a return on the capital invested. Current customer billing rates for the renewable cost recovery
rider were approved by the MPUC in a December 2020 order. On February 2, 2022, Minnesota Power submitted its 2022 renewable factor filing. Upon
approval of the filing, Minnesota Power will be authorized to include updated billing rates on customer bills.

Solar Cost Recovery Rider. In June 2020, Minnesota Power filed a petition seeking MPUC approval of a customer billing rate for solar costs related to
investments and expenditures for meeting the state of Minnesota’s solar energy standard, which was approved by the MPUC in an order dated April 20,
2021. New customer billing rates for the solar cost recovery rider were implemented on June 1, 2021. On October 21, 2021, Minnesota Power submitted its
2022 solar factor filing. Upon approval of the filing, Minnesota Power will be authorized to include updated billing rates on customer bills.

Environmental Improvement Rider. Minnesota Power has an approved environmental improvement rider for investments and expenditures related to the
implementation  of  the  Boswell  Unit  4  mercury  emissions  reduction  plan  completed  in  2015.  Updated  customer  billing  rates  for  the  environmental
improvement  rider  were  approved  by  the  MPUC  in  a  November  2018  order.  On  January  19,  2021,  Minnesota  Power  filed  a  petition  seeking  MPUC
approval to end the environmental improvement rider, which was approved in an order dated April 20, 2021. The environmental improvement rider ended
effective October 1, 2021.

Electric Vehicle Charging Infrastructure Petition. On April 8, 2021, Minnesota Power filed a petition seeking approval to install and own DC fast charger
stations for electric vehicles across its service territory, implement accompanying rates for those stations, and track and recover investments and expenses
for the project. In an order dated October 22, 2021, the MPUC approved Minnesota Power’s petition.

Fuel  Adjustment  Clause.  The  costs  of  fuel  and  related  transportation  costs  for  Minnesota  Power’s  generation  as  well  as  costs  of  purchased  power  for
Minnesota  Power  are  recoverable  from  Minnesota  Power’s  utility  retail  customers  through  the  fuel  adjustment  clause  (FAC).  The  FAC  for  Minnesota
electric utilities is a monthly budgeted, forward-looking process with annual prudence review and true-up to actual allowed costs. In May 2020, Minnesota
Power filed its fuel adjustment forecast for 2021, which was approved by the MPUC in a December 2020 order, subject to the annual prudence review and
true-up filing in 2022. During 2021, Minnesota Power incurred higher fuel and purchased power costs than those forecasted in its May 2020 filing, which
resulted in the recognition of an approximately $56 million regulatory asset as of December 31, 2021. Minnesota Power will make its annual true-up filing
and a significant events filing in March 2022 requesting recovery of these under-collected fuel adjustment clause recoveries.

In  March  2020,  Minnesota  Power  filed  its  FAC  report  covering  the  period  July  2018  through  December  2019.  In  a  September  2020  order,  the  MPUC
referred the review of Minnesota Power’s forced outage costs during the period of the report, which totaled approximately $8 million, to an administrative
law judge (ALJ) for a contested case hearing to recommend to the MPUC if any of those costs should be returned to customers. On August 11, 2021, the
ALJ recommended that Minnesota Power refund approximately $5 million to ratepayers. Minnesota Power submitted exceptions to the ALJ’s report to the
MPUC stating that it disagreed with the ALJ’s recommendation and that no refund should be made as the Company operated its facilities in accordance
with good utility practice. At a hearing on January 13, 2022, the MPUC agreed with the ALJ’s recommendation and ordered the refund of approximately
$5 million to ratepayers, which was recorded as a reserve as of December 31, 2021.

COVID-19 Related Deferred Accounting. In a March 2020 order, the PSCW authorized public utilities, including SWL&P, to defer expenditures incurred
by the utility resulting from its compliance with state government or regulator orders during Wisconsin’s declared public health emergency for COVID-
19. In a May 2020 order, the MPUC required Minnesota Power along with other regulated electric and natural gas service providers in Minnesota to track
cost  and  revenue  impacts  resulting  from  the  COVID-19  pandemic  with  review  for  recovery  in  a  future  rate  proceeding.  As  of  December  31,  2021,
Minnesota Power has not deferred any costs or lost revenue, and SWL&P has deferred an immaterial amount of costs.

Minnesota Power submitted a petition in November 2020 to the MPUC requesting authority to track and record as a regulatory asset lost large industrial
customer revenue resulting from the idling of USS Corporation’s Keetac plant and Verso Corporation’s paper mill in Duluth, Minnesota. In an order dated
May 13, 2021, the MPUC denied Minnesota Power’s request.

2018 Wisconsin General Rate Case. SWL&P’s current retail rates are based on a December 2018 order by the PSCW that allows for a return on equity of
10.4 percent and a 55.0 percent equity ratio. The PSCW had directed SWL&P to file its next general rate case in 2020; however, the PSCW granted an
extension  request  made  by  SWL&P  to  delay  filing  its  next  general  rate  case  until  on  or  before  December  20,  2022.  SWL&P  requested  the  extension
primarily due to impacts of the COVID-19 pandemic.

Integrated Resource Plan. In a 2016 order, the MPUC approved Minnesota Power’s 2015 IRP with modifications. The order accepted Minnesota Power’s
plans for the economic idling of Taconite Harbor Units 1 and 2 and the ceasing of coal-fired operations at Taconite Harbor in 2020, directed Minnesota
Power to retire Boswell Units 1 and 2, required an analysis of generation and demand response alternatives to be filed with a natural gas resource proposal,
and  required  Minnesota  Power  to  conduct  requests  for  proposal  for  additional  wind,  solar  and  demand  response  resource  additions.  Minnesota  Power
retired Boswell Units 1 and 2 in the fourth quarter of 2018.

2021 Integrated Resource Plan. On February 1, 2021, Minnesota Power filed its latest IRP with the MPUC, which outlines its clean-energy transition plans
through  2035.  These  plans  include  expanding  its  renewable  energy  supply,  achieving  coal-free  operations  at  its  facilities  by  2035,  and  investing  in  a
resilient and flexible transmission and distribution grid. As part of these plans, Minnesota Power anticipates adding approximately 400 MW of new wind
and solar energy resources, retiring Boswell Unit 3 by 2030 and transforming Boswell Unit 4 to be coal-free by 2035. Minnesota Power’s plans recognize
that advances in technology will play a significant role in completing its transition to carbon-free energy supply, reliably and affordably. A final decision on
the IRP is expected in the second half of 2022.

NOTE 4. REGULATORY MATTERS (Continued)

Nemadji Trail Energy Center. In 2017, Minnesota Power submitted a resource package to the MPUC which included requesting approval of a natural gas
capacity dedication and other affiliated-interest agreements for NTEC, an approximately 600 MW proposed combined-cycle natural gas-fired generating
facility to be built in Superior, Wisconsin, which will be jointly owned by Dairyland Power Cooperative, Basin and South Shore Energy, ALLETE’s non-
rate regulated, Wisconsin subsidiary. Minnesota Power is expected to purchase approximately 20 percent of the facility's output starting in 2025 pursuant to
the capacity dedication agreement. (See Note 1. Operations and Significant Accounting Policies.) In a January 2019 order, the MPUC approved Minnesota
Power’s request for approval of the NTEC natural gas capacity dedication and other affiliated-interest agreements. In 2019, the Minnesota Court of Appeals
reversed and remanded the MPUC’s decision to approve certain affiliated-interest agreements. On April 21, 2021, the Minnesota Supreme Court reversed
the Minnesota Court of Appeal’s decision by ruling that the MPUC is not required to conduct a review under the Minnesota Environmental Policy Act
before approving affiliated-interest agreements that govern construction and operation of a Wisconsin power plant by a Minnesota utility, and remanded the
case back to the Minnesota Court of Appeals for review of remaining issues on appeal. On August 23, 2021, the Minnesota Court of Appeals affirmed the
decision by the MPUC to approve certain affiliated-interest agreements.

Conservation Improvement Program. Minnesota  requires  electric  utilities  to  spend  a  minimum  of  1.5  percent  of  gross  operating  revenues,  excluding
revenue received from exempt customers, from service provided in the state on energy CIPs each year.

On April 1, 2021, Minnesota Power submitted its 2020 consolidated filing detailing Minnesota Power’s CIP program results and requesting a CIP financial
incentive of $2.4 million based upon MPUC procedures, which was recognized in the third quarter of 2021 upon approval by the MPUC in an order dated
September  7,  2021.  In  2020,  a  CIP  financial  incentive  of  $2.4  million  was  recognized  in  the  third  quarter  upon  approval  by  the  MPUC  of  Minnesota
Power’s 2019 CIP consolidated filing. CIP financial incentives are recognized in the period in which the MPUC approves the filing.

In July 2020, Minnesota Power submitted its CIP triennial filing for 2021 through 2023 to the MPUC and Minnesota Department of Commerce, which
outlines Minnesota Power’s CIP spending and energy-saving goals for those years. Minnesota Power’s CIP investment goals are $10.7 million for 2022 and
$10.9 million for 2023.

MISO Return on Equity Complaint. MISO transmission owners, including ALLETE and ATC, have an authorized return on equity of 10.02 percent, or
10.52 percent including an incentive adder for participation in a regional transmission organization based on a 2020 FERC order that granted rehearing of a
2019 FERC order. These FERC orders are subject to various outstanding legal challenges related to the refund period ordered by the FERC.

Minnesota Solar Energy Standard. Minnesota law requires at least 1.5 percent of total retail electric sales, excluding sales to certain customers, to be
generated by solar energy. At least 10 percent of the 1.5 percent mandate must be met by solar energy generated by or procured from solar photovoltaic
devices with a nameplate capacity of 40 kW or less and community solar garden subscriptions. Minnesota Power has met both parts of the solar mandate to
date.

In May 2020, the MPUC issued a notice requesting all regulated gas and electric utilities provide a list of all ongoing, planned, or possible investments that
support Minnesota’s energy policy objectives and aid economic recovery in Minnesota, among other items. In June 2020, Minnesota Power filed proposal
with the MPUC to accelerate its plans for purchasing solar energy from approximately 20 MW of solar energy projects in Minnesota which was approved
in  a  June  2021  order.  These  solar  energy  projects  will  be  constructed  and  owned  through  an  ALLETE  subsidiary  with  an  estimated  investment  of
$40 million. Construction of these solar energy projects is expected to commence in 2022.

Regulatory  Assets  and  Liabilities.  Our  regulated  utility  operations  are  subject  to  accounting  standards  for  the  effects  of  certain  types  of  regulation.
Regulatory  assets  represent  incurred  costs  that  have  been  deferred  as  they  are  probable  for  recovery  in  customer  rates.  Regulatory  liabilities  represent
obligations to make refunds to customers and amounts collected in rates for which the related costs have not yet been incurred. The Company assesses
quarterly whether regulatory assets and liabilities meet the criteria for probability of future recovery or deferral. With the exception of the regulatory asset
for Boswell Units 1 and 2 net plant and equipment, no other regulatory assets are currently earning a return. The recovery, refund or credit to rates for these
regulatory assets and liabilities will occur over the periods either specified by the applicable regulatory authority or over the corresponding period related to
the asset or liability.

ATC’s authorized return on equity is 10.02 percent, or 10.52 percent including an incentive adder for participation in a regional transmission organization,
based on a 2020 FERC order that granted rehearing of a 2019 FERC order. These FERC orders are subject to various outstanding legal challenges related
to  the  refund  period  ordered  by  the  FERC.  If  these  legal  challenges  are  successful,  ATC  may  be  required  to  provide  refunds  to  its  customers  of  up  to
approximately $65 million of which our share would be approximately $5 million pre-tax. In addition, the FERC issued a Notice of Proposed Rulemaking
in April 2021 proposing to limit the 50 basis point incentive adder for participation in a regional transmission organization to only the first three years of
membership in such an organization. If this proposal is adopted, our equity in earnings from ATC would be reduced by approximately $1 million pre-tax
annually.

NOTE 6. FAIR VALUE

Fair  value  is  the  price  that  would  be  received  to  sell  an  asset  or  paid  to  transfer  a  liability  in  an  orderly  transaction  between  market  participants  at  the
measurement  date  (exit  price).  We  utilize  market  data  or  assumptions  that  market  participants  would  use  in  pricing  the  asset  or  liability,  including
assumptions  about  risk  and  the  risks  inherent  in  the  inputs  to  the  valuation  technique.  These  inputs  can  be  readily  observable,  market  corroborated,  or
generally  unobservable.  We  primarily  apply  the  market  approach  for  recurring  fair  value  measurements  and  endeavor  to  utilize  the  best  available
information. Accordingly, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. These
inputs, which are used to measure fair value, are prioritized through the fair value hierarchy. The hierarchy gives the highest priority to unadjusted quoted
prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The
three levels of the fair value hierarchy are as follows:

Level  1  —  Quoted  prices  are  available  in  active  markets  for  identical  assets  or  liabilities  as  of  the  reported  date.  Active  markets  are  those  in  which
transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. This category includes
primarily equity securities.

Level 2 — Pricing inputs are other than quoted prices in active markets, but are either directly or indirectly observable as of the reported date. The types of
assets and liabilities included in Level 2 are typically either comparable to actively traded securities or contracts, such as treasury securities with pricing
interpolated  from  recent  trades  of  similar  securities,  or  priced  with  models  using  highly  observable  inputs,  such  as  commodity  options  priced  using
observable forward prices and volatilities. This category includes deferred compensation and fixed income securities.

Level 3 — Significant inputs that are generally less observable from objective sources. The types of assets and liabilities included in Level 3 are those with
inputs requiring significant management judgment or estimation, such as the complex and subjective models and forecasts used to determine the fair value.

NOTE 6. FAIR VALUE (Continued)

The following tables set forth by level within the fair value hierarchy, our assets and liabilities that were accounted for at fair value on a recurring basis as
of December 31, 2021, and December 31, 2020. Each asset and liability is classified based on the lowest level of input that is significant to the fair value
measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of
these assets and liabilities and their placement within the fair value hierarchy levels. The estimated fair value of Cash and Cash Equivalents listed on the
Consolidated Balance Sheet approximates the carrying amount and therefore is excluded from the recurring fair value measures in the following tables.

The Company’s policy is to recognize transfers in and transfers out of Levels as of the actual date of the event or change in circumstances that caused the
transfer. For the years ended December 31, 2021 and 2020, there were no transfers in or out of Levels 1, 2 or 3.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis. Non-financial assets such as equity method investments, goodwill, intangible
assets,  and  property,  plant  and  equipment  are  measured  at  fair  value  when  there  is  an  indicator  of  impairment  and  recorded  at  fair  value  only  when  an
impairment is recognized.

Equity Method Investments. The aggregate carrying amount of our equity investments was $318.0 million as of December 31, 2021 ($301.2 million as of
December 31, 2020). The Company assesses our equity investments in ATC and Nobles 2 for impairment whenever events or changes in circumstances
indicate that the carrying amount of our investments may not be recoverable. For the years ended December 31, 2021 and 2020, there were no indicators of
impairment. (See Note 5. Equity Investments.)

Property, Plant and Equipment. The Company assesses the impairment of property, plant, and equipment whenever events or changes in circumstances
indicate that the carrying amount of property, plant, and equipment assets may not be recoverable. (See Note 1. Operations and Significant Accounting
Policies.) For the years ended December 31, 2021, and 2020, there was no impairment of property, plant, and equipment.

We  believe  that  long-standing  ratemaking  practices  approved  by  applicable  state  and  federal  regulatory  commissions  allow  for  the  recovery  of  the
remaining  book  value  of  retired  plant  assets.  Minnesota  Power’s  2015  IRP  contained  steps  in  Minnesota  Power’s  EnergyForward  plan  including  the
economic idling of Taconite Harbor Units 1 and 2 in 2016, and the ceasing of coal-fired operations at Taconite Harbor in 2020. As of December 31, 2021,
Taconite Harbor had a net book value of approximately $45 million. The MPUC order for the 2015 IRP also directed Minnesota Power to retire Boswell
Units 1 and 2, which occurred in the fourth quarter of 2018. As part of the 2016 general retail rate case, the MPUC allowed recovery of the remaining book
value of Boswell Units 1 and 2 through 2022. In its latest IRP filing, Minnesota Power proposed retiring Boswell Unit 3 by 2030 and transforming Boswell
Unit  4  to  be  coal-free  by  2035.  Boswell  Unit  3  and  Unit  4  have  a  net  book  value  of  approximately  $245  million  and  $435  million,  respectively,  as  of
December 31, 2021. (See Note 4. Regulatory Matters.) We do not expect to record any impairment charge as a result of these operating changes at Taconite
Harbor and Boswell. In addition, we expect to be able to continue depreciating these assets for at least their established remaining useful lives; however, we
are unable to predict the impact of regulatory outcomes resulting in changes to their established remaining useful lives.

NOTE 7. SHORT-TERM AND LONG-TERM DEBT

Short-Term  Debt.  As  of  December  31,  2021,  total  short-term  debt  outstanding  was  $214.2  million  ($203.7  million  as  of  December  31,  2020),  and
consisted of long-term debt due within one year and included $0.2 million of unamortized debt issuance costs.

As of December 31, 2021, we had consolidated bank lines of credit aggregating $432.0 million ($407.0 million as of December 31, 2020), most of which
expire in January 2025. We had $31.5 million outstanding in standby letters of credit and $159.7 million outstanding draws under our lines of credit as of
December 31, 2021 ($22.3 million in standby letters of credit and no outstanding draws as of December 31, 2020).

NOTE 7. SHORT-TERM AND LONG-TERM DEBT (Continued)

Long-Term Debt.  As  of  December  31,  2021,  total  long-term  debt  outstanding  was  $1,763.2  million  ($1,593.2  million  as  of  December  31,  2020)  and
included $8.8 million of unamortized debt issuance costs. The aggregate amount of long-term debt maturing in 2022 is $214.5 million; $89.7 million in
2023; $74.4 million in 2024; $386.7 million in 2025; $77.2 million in 2026; and $1,143.9 million thereafter. Substantially all of our regulated electric plant
is subject to the lien of the mortgages collateralizing outstanding first mortgage bonds. The mortgages contain non-financial covenants customary in utility
mortgages, including restrictions on our ability to incur liens, dispose of assets, and merge with other entities.

Minnesota Power is obligated to make financing payments for the Camp Ripley solar array totaling $1.4 million annually during the financing term, which
expires  in  2027.  Minnesota  Power  has  the  option  at  the  end  of  the  financing  term  to  renew  for  a  two‑year  term,  or  to  purchase  the  solar  array  for
approximately $4 million. Minnesota Power anticipates exercising the purchase option when the term expires.

On March 25, 2021, ALLETE entered into a $150 million unsecured term loan agreement (Term Loan). An additional draw of $35 million through the
exercise  of  an  accordion  feature  was  made  during  the  second  quarter  of  2021.  As  of  September  30,  2021,  we  have  borrowed  the  full  amount  of
$185 million. The Term Loan is due March 24, 2022, and may be repaid at any time. Interest is payable monthly at a rate per annum equal to LIBOR plus
0.75 percent. Proceeds from the Term Loan were used for general corporate purposes.

On September 1, 2021, ALLETE issued $100 million of its First Mortgage Bonds (Bonds) to certain institutional buyers in the private placement market.
The  Bonds,  which  bear  interest  at  2.79  percent,  will  mature  in  September  2031  and  pay  interest  semi-annually  in  March  and  September  of  each  year,
commencing on March 1, 2022. ALLETE has the option to prepay all or a portion of the Bonds at its discretion, subject to a make-whole provision. The
Bonds are subject to additional terms and conditions which are customary for these types of transactions. Proceeds from the sale of the Bonds were used to
fund utility capital investment and for general corporate purposes. The Bonds were sold in reliance on an exemption from registration under Section 4(a)(2)
of the Securities Act of 1933, as amended, to institutional accredited investors.

In  January  2022,  ALLETE  Clean  Energy  received  approximately  $183.0  million  from  final  closing  of  tax  equity  funding  for  the  Caddo  wind  energy
facility. The proceeds from the funding were used to pay down a portion of outstanding draws on our lines of credit.

NOTE 7. SHORT-TERM AND LONG-TERM DEBT (Continued)
Long-Term Debt (Continued)

Financial Covenants. Our long-term debt arrangements contain customary covenants. In addition, our lines of credit and letters of credit supporting certain
long-term debt arrangements contain financial covenants. Our compliance with financial covenants is not dependent on debt ratings. The most restrictive
financial  covenant  requires  ALLETE  to  maintain  a  ratio  of  indebtedness  to  total  capitalization  (as  the  amounts  are  calculated  in  accordance  with  the
respective long-term debt arrangements) of less than or equal to 0.65 to 1.00, measured quarterly. As of December 31, 2021, our ratio was approximately
0.41 to 1.00. Failure to meet this covenant would give rise to an event of default if not cured after notice from the lender, in which event ALLETE may
need to pursue alternative sources of funding. Some of ALLETE’s debt arrangements contain “cross-default” provisions that would result in an event of
default if there is a failure under other financing arrangements to meet payment terms or to observe other covenants that would result in an acceleration of
payments  due.  ALLETE  has  no  significant  restrictions  on  its  ability  to  pay  dividends  from  retained  earnings  or  net  income.  As  of  December  31,  2021,
ALLETE was in compliance with its financial covenants.

(a) Easement obligations represent the minimum payments for our land easement agreements at our wind energy facilities.
(b) Does not include the agreement with Manitoba Hydro expiring in 2022, as this contract is for surplus energy only; or the Oliver Wind I, Oliver Wind II or Nobles 2

PPAs, as Minnesota Power only pays for energy as it is delivered. (See Power Purchase Agreements.)

(c) Consists of long-term service agreements for wind energy facilities and minimum purchase commitments under coal and rail contracts.

Power Purchase and Sales Agreements. Our long-term PPAs have been evaluated under the accounting guidance for variable interest entities. We have
determined  that  either  we  have  no  variable  interest  in  the  PPAs,  or  where  we  do  have  variable  interests,  we  are  not  the  primary  beneficiary;  therefore,
consolidation is not required. These conclusions are based on the fact that we do not have both control over activities that are most significant to the entity
and an obligation to absorb losses or receive benefits from the entity’s performance. Our financial exposure relating to these PPAs is limited to our capacity
and energy payments.

These  agreements  have  also  been  evaluated  under  the  accounting  guidance  for  derivatives.  We  have  determined  that  either  these  agreements  are  not
derivatives,  or,  if  they  are  derivatives,  the  agreements  qualify  for  the  normal  purchases  and  normal  sales  exception  to  derivative  accounting  guidance;
therefore, derivative accounting is not required.

Square Butte PPA. Minnesota Power has a PPA with Square Butte that extends through 2026 (Agreement). Minnesota Power is obligated to pay its pro rata
share  of  Square  Butte’s  costs  based  on  its  entitlement  to  the  output  of  Square  Butte’s  455  MW  coal‑fired  generating  unit.  Minnesota  Power’s  output
entitlement under the Agreement is 50 percent for the remainder of the Agreement, subject to the provisions of the Minnkota Power PSA described in the
following table. 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  costs  consist  primarily  of  debt  service,  operating  and  maintenance,  depreciation  and  fuel  expenses.  As  of
December 31, 2021, Square Butte had total debt outstanding of $222.6 million. Annual debt service for Square Butte is expected to be approximately $45.5
million  annually  through  2023,  $30.5  million  in  2024,  $26.6  million  in  2025,  and  $40.1  million  in  2026,  of  which  Minnesota  Power’s  obligation  is
50  percent.  Fuel  expenses  are  recoverable  through  Minnesota  Power’s  fuel  adjustment  clause  and  include  the  cost  of  coal  purchased  from  BNI  Energy
under a long-term contract.

NOTE 8. COMMITMENTS, GUARANTEES AND CONTINGENCIES (Continued)
Power Purchase and Sales Agreements (Continued)

Minnesota Power’s cost of power purchased from Square Butte during 2021 was $82.4 million ($79.5 million in 2020; $82.7 million in 2019). This reflects
Minnesota Power’s pro rata share of total Square Butte costs based on the 50 percent output entitlement. Included in this amount was Minnesota Power’s
pro rata share of interest expense of $5.8 million in 2021 ($7.1 million in 2020; $8.3 million in 2019). Minnesota Power’s payments to Square Butte are
approved as a purchased power expense for ratemaking purposes by both the MPUC and the FERC.

Coal,  Rail  and  Shipping  Contracts.  Minnesota  Power  has  coal  supply  agreements  providing  for  the  purchase  of  a  significant  portion  of  its  coal
requirements through December 2022. Minnesota Power also has coal transportation agreements in place for the delivery of a significant portion of its coal
requirements through December 2024. The costs of fuel and related transportation costs for Minnesota Power’s generation are recoverable from Minnesota
Power’s utility customers through the fuel adjustment clause.

Environmental Matters.

Our businesses are subject to regulation of environmental matters by various federal, state and local authorities. A number of regulatory changes to the
Clean Air Act, the Clean Water Act and various waste management requirements have been promulgated by both the EPA and state authorities over the
past several years. Minnesota Power’s facilities are subject to additional requirements under many of these regulations. Minnesota Power is reshaping its
generation portfolio, over time, to reduce its reliance on coal, has installed cost-effective emission control technology, and advocates for sound science and
policy during rulemaking implementation.

We consider our businesses to be in substantial compliance with currently applicable environmental regulations and believe all necessary permits have been
obtained.  We  anticipate  that  with  many  state  and  federal  environmental  regulations  and  requirements  finalized,  or  to  be  finalized  in  the  near  future,
potential expenditures for future environmental matters may be material and require significant capital investments. Minnesota Power has evaluated various
environmental compliance scenarios using possible outcomes of environmental regulations to project power supply trends and impacts on customers.

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. Accruals are adjusted as assessment
and remediation efforts progress, or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in
the  Consolidated  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 expensed unless recoverable in rates from customers.

Air. The electric utility industry is regulated both at the federal and state level to address air emissions. Minnesota Power’s thermal generating facilities
mainly  burn  low-sulfur  western  sub-bituminous  coal.  All  of  Minnesota  Power’s  coal-fired  generating  facilities  are  equipped  with  pollution  control
equipment such as scrubbers, baghouses and low NO  technologies. Under currently applicable environmental regulations, these facilities are substantially
compliant with emission requirements.

Cross-State Air Pollution Rule (CSAPR). The CSAPR requires certain states in the eastern half of the U.S., including Minnesota, to reduce power plant
emissions  that  contribute  to  ozone  or  fine  particulate  pollution  in  other  states.  The  CSAPR  does  not  require  installation  of  controls  but  does  require
facilities  have  sufficient  allowances  to  cover  their  emissions  on  an  annual  basis.  These  allowances  are  allocated  to  facilities  from  each  state’s  annual
budget, and can be bought and sold. Based on our review of the NO  and SO  allowances issued and pending issuance, we currently expect generation
levels and emission rates will result in continued compliance with the CSAPR. The EPA’s CSAPR Update Rule issued on March 15, 2021, to revise the
2016 CSAPR Update does not apply to the state of Minnesota and is therefore not currently projected to affect Minnesota Power’s CSAPR compliance.
The  State  of  Minnesota  has  not  been  identified  in  litigation  as  a  culpable  upwind  emission  source  to  downwind  states,  and  previous  EPA  air  quality
modeling has demonstrated that Minnesota is not a significant contributor to downwind air quality attainment challenges. Minnesota Power will continue to
monitor ongoing CSAPR rulemakings and compliance implementation.

National Ambient Air Quality Standards (NAAQS). The EPA is required to review the NAAQS every five years. If the EPA determines that a state’s air
quality is not in compliance with the NAAQS, the state is required to adopt plans describing how it will reduce emissions to attain the NAAQS. Minnesota
Power actively monitors NAAQS developments and compliance costs for existing standards or proposed NAAQS revisions are not currently expected to be
material. The EPA is currently reviewing the secondary NAAQS for NOx and SO , as well as particulate matter. On June 10, 2021, the EPA announced it
will reconsider the December 2020 final rule retaining the 2012 particulate matter NAAQS annual standard, with a proposed rulemaking anticipated in late
2022 and final action expected in early 2023. The EPA also stated it would complete reconsideration of the December 2020 Ozone NAAQS by the end of
2023.

Climate  Change.  The  scientific  community  generally  accepts  that  emissions  of  GHG  are  linked  to  global  climate  change  which  creates  physical  and
financial risks. Physical risks could include, but are not limited to: increased or decreased precipitation and water levels in lakes and rivers; increased or
other changes in temperatures; and changes in the intensity and frequency of extreme weather events. These all have the potential to affect the Company’s
business and operations. We are addressing climate change by taking the following steps that also ensure reliable and environmentally compliant generation
resources to meet our customers’ requirements:

Expanding renewable power supply for both our operations and the operations of others;
Providing energy conservation initiatives for our customers and engaging in other demand side management efforts;
Improving efficiency of our generating facilities;
Supporting research of technologies to reduce carbon emissions from generating facilities and carbon sequestration efforts;
Evaluating and developing less carbon intensive future generating assets such as efficient and flexible natural gas‑fired generating facilities;

•
•
•
•
•
• Managing vegetation on right-of-way corridors to reduce potential wildfire or storm damage risks; and
•

Practicing  sound  forestry  management  in  our  service  territories  to  create  landscapes  more  resilient  to  disruption  from  climate-related  changes,
including planting and managing long-lived conifer species.

EPA Regulation of GHG Emissions. In 2019, the EPA finalized several separate rulemakings regarding regulating carbon emissions from electric utility
generating units. These rulemakings included repealing the Clean Power Plan (CPP) and adopting the Affordable Clean Energy Rule under Section 111(d)
of the Clean Air Act (CAA) to regulate CO  emissions at existing coal-fired power plants. The CPP was first announced as a proposed rule under Section
111(d) of the CAA for existing power plants entitled “Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Generating Units”.
The Affordable Clean Energy Rule established emissions guidelines for states to use when developing plans to limit CO  coal-fired power plants. The EPA
also  published  regulations  for  the  state  implementation  of  the  Affordable  Clean  Energy  Rule  and  other  Section  111(d)  rules.  Affected  facilities  for
Minnesota Power included Boswell Units 3 and 4, and Taconite Harbor Units 1 and 2, which are currently economically idled.

On January 19, 2021, the D.C. Circuit issued an opinion vacating the Affordable Clean Energy Rule and remanded the Affordable Clean Energy Rule back
to the EPA for further consideration, consistent with the D.C. Circuit’s finding that the EPA erred in interpreting the CAA, pending rehearing or appeal.
Four petitions were subsequently granted for review by the U.S. Supreme Court on October 29, 2021, with a decision expected in mid-2022.

The EPA also indicated that it intends to issue a proposed rule in mid-2022 and a final rule in mid-2023 with a new set of emission guidelines for states to
follow in submitting state plans to establish and implement standards of performance for GHG emissions from existing fossil fuel-fired electric generating
units. Minnesota Power will continue to monitor any related guidelines and rulemakings issued by the EPA or state regulatory authorities.

On  April  22,  2021,  the  Biden  Administration  announced  a  goal  to  reach  100  percent  carbon  pollution-free  electricity  by  2035  as  part  of  the  Nationally
Determined Contributions pledge, which is part of an international effort to limit global warming. At this time, no specific regulatory pathway to achieve
these reductions has been proposed. Minnesota Power will continue to monitor these developments.

Minnesota had already initiated several measures consistent with those called for under the now repealed CPP and vacated Affordable Clean Energy Rule.
Minnesota Power continues implementing its EnergyForward strategic plan that provides for significant emission reductions and diversifying its electricity
generation mix to include more renewable and natural gas energy. We are unable to predict the GHG emission compliance costs we might incur as a result
of a replacement for the Affordable Clean Energy Rule or other future laws, regulations or administrative policies; however, the costs could be material.
Minnesota Power would seek recovery of additional costs through a rate proceeding.

NOTE 8. COMMITMENTS, GUARANTEES AND CONTINGENCIES (Continued)
Environmental Matters (Continued)

Additionally on January 13, 2021, the EPA issued a rulemaking to apply CO  emission New Source Performance Standards (NSPS) to new, modified and
2
reconstructed fossil fuel-fired electric generating units under Section 111(b) of the CAA. In April 2021, the EPA requested and was allowed to voluntarily
vacate and remand the Significant Contribution Finding determination criteria related to this NSPS. The EPA intends to issue a proposed rule in mid-2022
and a final rule by mid-2023. Minnesota Power is monitoring the NSPS final rule and any further Section 111(b) developments including their potential
impact  to  the  Company.  The  Company’s  proposed  combined-cycle  natural  gas-fired  generating  facility,  NTEC,  is  expected  to  meet  these  NSPS
requirements.

Water. The Clean Water Act requires NPDES permits be obtained from the EPA (or, when delegated, from individual state pollution control agencies) for
any wastewater discharged into navigable waters. We have obtained all necessary NPDES permits, including NPDES storm water permits for applicable
facilities, to conduct our operations.

Steam Electric Power Generating Effluent Limitations Guidelines. In 2015, the EPA issued revised federal effluent limitation guidelines (ELG) for steam
electric power generating stations under the Clean Water Act. It set effluent limits and prescribed BACT for several wastewater streams, including flue gas
desulphurization (FGD) water, bottom ash transport water and coal combustion landfill leachate. In 2017, the EPA announced a two-year postponement of
the ELG compliance date of November 1, 2018, to November 1, 2020, while the agency reconsidered the bottom ash transport water and FGD wastewater
provisions. On April 12, 2019, the U.S. Court of Appeals for the Fifth Circuit vacated and remanded back to the EPA portions of the ELG that allowed for
continued discharge of legacy wastewater and leachate. On October 13, 2020, the EPA published a final ELG Rule allowing re-use of bottom ash transport
water  in  FGD  scrubber  systems  with  limited  discharges  related  to  maintaining  system  water  balance.  The  rule  sets  technology  standards  and  numerical
pollutant  limits  for  discharges  of  bottom  ash  transport  water  and  FGD  wastewater.  Compliance  deadlines  depend  on  subcategory,  with  compliance
generally required as soon as possible, beginning after October 13, 2021, but no later than December 31, 2025, or December 31, 2028, in some specific
cases. The rule also established new subcategories for retiring high-flow and low-utilization units, and established a voluntary incentives program for FGD
wastewater. In accordance with the January 2021 Executive Order 13990, the EPA was mandated to conduct a review of actions and polices taken during
the  prior  administration,  including  the  2020  ELG  Rule.  On  September  14,  2021,  the  EPA  published  a  notice  of  availability  for  preliminary  effluent
guidelines program plan. In the plan, the EPA confirmed the agency is initiating a rulemaking process to strengthen wastewater pollution limitations from
FGD and bottom ash transport water discharges while the 2020 ELG Rule remains in effect. The EPA is expected to publish a proposed rule in the fall of
2022.

The  ELG's  potential  impact  on  Minnesota  Power  operations  is  primarily  at  Boswell.  Boswell  currently  discharges  bottom  ash  contact  water  through  its
NPDES permit, and also has a closed-loop FGD system that does not discharge to surface waters, but may do so in the future. With Boswell’s planned
conversion to dry FGD handling and storage, ongoing FGD water generation will be reduced, and the majority of FGD waters will be legacy waters to be
dewatered from existing impoundments. Re-use and onsite consumption for the majority of FGD waters is planned at Boswell.

Under  the  new  ELG  rule,  most  bottom  ash  transport  water  discharge  to  surface  waters  must  cease  no  later  than  December  31,  2025,  except  for  small
discharges needed to retain water balance. The majority of bottom ash transport water will either need to be re-used in a closed-loop process or routed to a
FGD scrubber. At Boswell, the bottom ash handling systems are planned to be converted to a dry process, which will eliminate the discharge of bottom ash
transport water.

The EPA’s additional reconsideration of legacy wastewater discharge requirements has the potential to reduce timelines for dewatering Boswell’s existing
ponds. The EPA has withdrawn its separate action regarding the 2015 leachate and legacy wastewater ELGs and intends to consolidate that reconsideration
with the 2020 bottom ash transport water and FGD ELG reconsideration. A proposed rule is expected in late 2022.

ALLETE, Inc. 2021 Form 10-K

NOTE 8. COMMITMENTS, GUARANTEES AND CONTINGENCIES (Continued)
Environmental Matters (Continued)

At this time, we estimate that the planned dry conversion of bottom ash handling and storage at Boswell in response to the CCR revisions requiring closure
of clay-lined impoundments, as well as other water re-use practices, will reduce or eliminate the need for additional significant compliance costs for ELG
bottom ash water and FGD requirements. Compliance costs we might incur related to other ELG waste streams (e.g., legacy leachate) or other potential
future water discharge regulations cannot be estimated; however, the costs could be material, including costs associated with wastewater treatment and re-
use. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Permitted Water Discharges – Sulfate. In 2017, the MPCA released a draft water quality standard in an attempt to update Minnesota’s existing 10 mg/L
sulfate limit for waters used for the production of wild rice with the proposed rulemaking heard before an administrative law judge (ALJ). In 2018, the ALJ
rejected  significant  portions  of  the  proposed  rulemaking  and  the  MPCA  subsequently  withdrew  the  rulemaking.  The  existing  10  mg/L  limit  remains  in
place, but the MPCA is currently prohibited under state law from listing wild rice waters as impaired or requiring sulfate reduction technology.

In April 2021, the MPCA’s proposed list of impaired waters submitted pursuant to the Clean Water Act was partially rejected by the EPA due to the absence
of wild rice waters listed for sulfate impairment. The EPA subsequently proposed a list of 30 wild rice waters in a separate listing process on April 29,
2021,  followed  by  a  list  of  three  additional  wild  rice  waters  proposed  separately  on  September  1,  2021.  A  final  impaired  waters  listing  is  expected  to
follow, which could subsequently be used to set sulfate limits in discharge permits for power generation facilities and municipal and industrial customers,
including paper and pulp facilities, and mining operations. At this time we are unable to determine the specific impacts these developments may have on
Minnesota Power operations, if any. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Solid and Hazardous Waste. The Resource Conservation and Recovery Act of 1976 regulates the management and disposal of solid and hazardous wastes.
We are required to notify the EPA of hazardous waste activity and, consequently, routinely submit reports to the EPA.

Coal  Ash  Management  Facilities.  Minnesota  Power  produces  the  majority  of  its  coal  ash  at  Boswell,  with  small  amounts  of  ash  generated  at  Hibbard
Renewable Energy Center. Ash storage and disposal methods include storing ash in clay-lined onsite impoundments (ash ponds), disposing of dry ash in a
lined dry ash landfill, applying ash to land as an approved beneficial use, and trucking ash to state permitted landfills.

Coal Combustion Residuals from Electric Utilities (CCR). In 2015, the EPA published the final rule regulating CCR as nonhazardous waste under Subtitle
D  of  the  Resource  Conservation  and  Recovery  Act  (RCRA)  in  the  Federal  Register.  The  rule  includes  additional  requirements  for  new  landfill  and
impoundment construction as well as closure activities related to certain existing impoundments. Costs of compliance for Boswell and Laskin are expected
to be incurred primarily over the next 15 years and be between approximately $65 million and $120 million. Compliance costs for CCR at Taconite Harbor
are not expected to be material. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Minnesota Power continues to work on minimizing costs through evaluation of beneficial re-use and recycling of CCR and CCR-related waters. In 2017,
the EPA announced its intention to formally reconsider the CCR rule under Subtitle D of the RCRA. In March 2018, the EPA published the first phase of
the proposed rule revisions in the Federal Register. In 2018, the EPA finalized revisions to elements of the CCR rule, including extending certain deadlines
by two years, the establishment of alternative groundwater protection standards for certain constituents and the potential for risk-based management options
at facilities based on site characteristics. In 2018, a U.S. District Court for the District of Columbia decision vacated specific provisions of the CCR rule.
The court decision resulted in a change to the status of three existing clay-lined impoundments at Boswell that must now be considered unlined. The EPA
proposed additional rule revisions in 2019 to address outstanding issues from litigation and closure timelines for unlined impoundments, respectively. The
first of these rules, CCR Part A Rule, was finalized in September 2020. The Part A Rule revision requires unlined impoundments to cease disposal of waste
as  soon  as  technically  feasible  but  no  later  than  April  11,  2021.  This  deadline  has  continued  to  toll  as  the  EPA  did  not  make  any  variance  application
determinations by that date. Minnesota Power sought EPA approval to extend the closure date for the two active Boswell impoundments in November 2020
through a variance application, and continues to operate the impoundments pending a final determination by the EPA. On January 11, 2022, the EPA issued
a number of Part A and Part B variance application completeness determinations. The Boswell application was deemed complete; an approval or denial of
the application is expected in mid-2022.

ALLETE, Inc. 2021 Form 10-K
102

NOTE 8. COMMITMENTS, GUARANTEES AND CONTINGENCIES (Continued)
Environmental Matters (Continued)

Additionally,  the  EPA  released  a  proposed  Part  B  rulemaking  in  2020  that  addressed  options  for  beneficial  reuse  of  CCR  materials,  alternative  liner
demonstrations,  and  other  CCR  regulatory  revisions.  Portions  of  the  Part  B  Rule  addressing  alternative  liner  equivalency  standards  were  finalized  in
November 2020. According to the EPA’s regulatory agenda, finalization of the remainder of the proposed Part B Rule is expected in late 2022. Expected
compliance costs at Boswell due to the court decision and subsequent rule revisions are reflected in our estimate of compliance costs for the CCR rule
noted previously. Minnesota Power would seek recovery of additional costs through a rate proceeding.

Other Environmental Matters

Manufactured  Gas  Plant  Site.  We  are  reviewing  and  addressing  environmental  conditions  at  a  former  manufactured  gas  plant  site  located  in  Superior,
Wisconsin, and formerly operated by SWL&P. SWL&P has been working with the Wisconsin Department of Natural Resources (WDNR) in determining
the extent and location of contamination at the site and surrounding properties. As of December 31, 2021, we have recorded a liability of approximately
$18 million for remediation costs at this site after further refining the scope of work and cost estimates as well as incorporating detailed design components
specific to the site in 2021 (approximately $7 million as of December 31, 2020); however, SWL&P continues to work with the WDNR on the extent of
contamination which may result in additional remediation costs being identified. SWL&P has also recorded an associated regulatory asset as we expect
recovery of these remediation costs to be allowed by the PSCW. Remediation costs are expected to be incurred through 2023.

Other Matters

We have multiple credit facility agreements in place that provide the ability to issue standby letters of credit to satisfy our contractual security requirements
across our businesses. As of December 31, 2021, we had $134.7 million of outstanding letters of credit issued, including those issued under our revolving
credit facility.

Regulated Operations.  As  of  December  31,  2021,  we  had  $10.9  million  outstanding  in  standby  letters  of  credit  at  our  Regulated  Operations  which  are
pledged as security for MISO and state agency agreements as well as energy facilities under development.

ALLETE Clean Energy. ALLETE Clean Energy’s wind energy facilities have PSAs in place for their output and expire in various years between 2022 and
2039. As of December 31, 2021, ALLETE Clean Energy has $87.4 million outstanding in standby letters of credit, the majority of which are pledged as
security under these PSAs and PSAs for wind energy facilities under development.

Corporate and Other.

BNI Energy. As of December 31, 2021, BNI Energy had surety bonds outstanding of $71.2 million related to the reclamation liability for closing costs
associated  with  its  mine  and  mine  facilities.  Although  its  coal  supply  agreements  obligate  the  customers  to  provide  for  the  closing  costs,  additional
assurance is required by federal and state regulations. BNI Energy’s total reclamation liability is currently estimated at $70.7 million. BNI Energy does not
believe it is likely that any of these outstanding surety bonds will be drawn upon.

Investment in Nobles 2. Nobles 2 wind energy facility requires standby letters of credit as security for certain contractual obligations. As of December 31,
2021, ALLETE South Wind has $12.5 million outstanding in standby letters of credit, related to our portion of the security requirements relative to our
ownership in Nobles 2.

South  Shore  Energy.  As  of  December  31,  2021,  South  Shore  Energy  had  $23.9  million  outstanding  in  standby  letters  of  credit  pledged  as  security  in
connection with the development of NTEC. South Shore Energy does not believe it is likely that any of these outstanding letters of credit will be drawn
upon.

ALLETE Properties. As of December 31, 2021, ALLETE Properties had surety bonds outstanding and letters of credit to governmental entities totaling
$2.0 million primarily related to development and maintenance obligations for various projects. The estimated cost of the remaining development work is
$1.0 million. ALLETE Properties does not believe it is likely that any of these outstanding surety bonds or letters of credit will be drawn upon.

Community  Development  District  Obligations.  In  2005,  the  Town  Center  District  issued  $26.4  million  of  tax-exempt,  6.0  percent  capital  improvement
revenue  bonds.  The  capital  improvement  revenue  bonds  are  payable  over  31  years  (by  May  1,  2036)  and  are  secured  by  special  assessments  on  the
benefited land. To the extent that ALLETE Properties still owns land at the time of the assessment, it will incur the cost of its portion of these assessments,
based upon its ownership of benefited property.

As  of  December  31,  2021,  we  owned  30  percent  of  the  assessable  land  in  the  Town  Center  District  (48  percent  as  of  December  31,  2020).  As  of
December 31, 2021, ownership levels, our annual assessments related to capital improvement and special assessment bonds for the ALLETE Properties
project within the district is approximately $1.8 million. As we sell property at this project, the obligation to pay special assessments will pass to the new
landowners. In accordance with accounting guidance, these bonds are not reflected as debt on our Consolidated Balance Sheet.

Legal Proceedings.

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, and compliance with regulations, rate
base  and  cost  of  service  issues,  among  other  things.  We  do  not  expect  the  outcome  of  these  matters  to  have  a  material  effect  on  our  financial  position,
results of operations or cash flows.

Minnesota Power has been named in a lawsuit where a contractor performing work at one of its facilities experienced an injury and subsequently filed a
lawsuit seeking compensatory damages. Litigation related to this injury is ongoing. At this time, a loss is considered reasonably possible; however, we do
not deem it probable, and we are unable to estimate a loss or range of loss related to the litigation at this time.

(a) For  the  years  ended  December  31,  2021,  2020  and  2019,  the  federal  and  state  current  tax  expense  was  minimal  due  to  NOLs  which  resulted  from  the  bonus

depreciation and related tax attributes from large wind projects. Federal and state NOLs are being carried forward to offset current and future taxable income.

(b) For the years ended December 31, 2021, 2020 and 2019, the federal tax benefit is primarily due to production tax credits.

(a) Excess deferred income taxes are being returned to customers under both the Average Rate Assumption Method and amortization periods as approved by regulators.

(See Note 4. Regulatory Matters.)

The effective tax rate was a benefit of 24.3 percent for 2021 (benefit of 32.4 percent for 2020; benefit of 3.7 percent for 2019). The 2021 effective tax rate
was  primarily  impacted  by  production  tax  credits  and  non-controlling  interests  in  subsidiaries.  The  2020  effective  tax  rate  was  primarily  impacted  by
production tax credits. The 2019 effective tax rate was primarily impacted by production tax credits and the gain on sale of U.S. Water Services.

Unrecognized tax benefits are the differences between a tax position taken or expected to be taken in a tax return and the benefit recognized and measured
pursuant to the “more-likely-than-not” criteria. The unrecognized tax benefit balance includes permanent tax positions which, if recognized would affect
the annual effective income tax rate. In addition, the unrecognized tax benefit balance includes temporary tax positions for which the ultimate deductibility
is  highly  certain  but  for  which  there  is  uncertainty  about  the  timing  of  such  deductibility.  A  change  in  the  period  of  deductibility  would  not  affect  the
effective  tax  rate  but  would  accelerate  the  payment  of  cash  to  the  taxing  authority  to  an  earlier  period.  The  gross  unrecognized  tax  benefits  as  of
December 31, 2021, included $0.6 million of net unrecognized tax benefits which, if recognized, would affect the annual effective income tax rate.

As  of  December  31,  2021,  we  had  no  accrued  interest  (none  as  of  December  31,  2020,  and  2019)  related  to  unrecognized  tax  benefits  included  on  the
Consolidated Balance Sheet due to our NOL carryforwards. We classify interest related to unrecognized tax benefits as interest expense and tax-related
penalties  in  operating  expenses  on  the  Consolidated  Statement  of  Income.  Interest  expense  related  to  unrecognized  tax  benefits  on  the  Consolidated
Statement of Income was immaterial in 2021, 2020 and 2019. There were no penalties recognized in 2021, 2020 or 2019. The unrecognized tax benefit
amounts have been presented as reductions to the tax benefits associated with NOL and tax credit carryforwards on the Consolidated Balance Sheet.

No material changes to unrecognized tax benefits are expected during the next 12 months.

ALLETE  and  its  subsidiaries  file  a  consolidated  federal  income  tax  return  as  well  as  combined  and  separate  state  income  tax  returns  in  various
jurisdictions. ALLETE has no open federal or state audits, and is no longer subject to federal examination for years before 2018 or state examination for
years before 2017.

NOTE 11. PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS

We have noncontributory union, non-union and combined retiree defined benefit pension plans covering eligible employees. The combined retiree defined
benefit  pension  plan  was  created  in  2016,  to  include  all  union  and  non-union  retirees  from  the  existing  plans  as  of  January  1,  2016.  The  plans  provide
defined benefits based on years of service and final average pay. We contributed $10.3 million in cash to the plans in 2021 ($10.7 million in 2020; $10.4
million in 2019). We also have a defined contribution RSOP covering substantially all employees. The 2021 plan year employer contributions, which are
made through the employee stock ownership plan portion of the RSOP, totaled $11.5 million ($11.2 million for the 2020 plan year; $10.8 million for the
2019 plan year). (See Note 9. Common Stock and Earnings Per Share and Note 12. Employee Stock and Incentive Plans.)

The non-union defined benefit pension plan was frozen in 2018, and does not allow further crediting of service or earnings to the plan. Further, it is closed
to new participants. The Minnesota Power union defined benefit pension plan is also closed to new participants, and the SWL&P union defined benefit
pension plan was closed to new participants effective February 1, 2022.

We  have  postretirement  health  care  and  life  insurance  plans  covering  eligible  employees.  In  2010,  the  postretirement  health  care  plan  was  closed  to
employees hired after January 31, 2011, and the eligibility requirements were amended. In 2014, the postretirement life plan was amended to close the plan
to  non-union  employees  retiring  after  December  31,  2015,  and  in  2018,  the  postretirement  life  plan  was  amended  to  limit  the  benefit  level  for  union
employees  retiring  after  December  31,  2018.  The  postretirement  health  and  life  plans  are  contributory  with  participant  contributions  adjusted  annually.
Postretirement health and life benefits are funded through a combination of Voluntary Employee Benefit Association trusts (VEBAs), established under
section 501(c)(9) of the Internal Revenue Code, and irrevocable grantor trusts. In 2021, no contributions were made to the VEBAs (none in 2020; none in
2019) and no contributions were made to the grantor trusts (none in 2020; none in 2019).

Management  considers  various  factors  when  making  funding  decisions  such  as  regulatory  requirements,  actuarially  determined  minimum  contribution
requirements and contributions required to avoid benefit restrictions for the pension plans. Contributions are based on estimates and assumptions which are
subject  to  change.  We  do  not  expect  to  make  any  contributions  to  the  defined  benefit  pension  plans  in  2022,  and  we  do  not  expect  to  make  any
contributions to the defined benefit postretirement health and life plans in 2022.

Accounting for defined benefit pension and other postretirement benefit plans requires that employers recognize on a prospective basis the funded status of
their defined benefit pension and other postretirement plans on their balance sheet and recognize as a component of other comprehensive income, net of
tax, the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic benefit cost.

The defined benefit pension and postretirement health and life benefit expense (credit) recognized annually by our regulated utilities are expected to be
recovered  (refunded)  through  rates  filed  with  our  regulatory  jurisdictions.  As  a  result,  these  amounts  that  are  required  to  otherwise  be  recognized  in
accumulated other comprehensive income have been recognized as a long-term regulatory asset (regulatory liability) on the Consolidated Balance Sheet, in
accordance with the accounting standards for the effect of certain types of regulation applicable to our Regulated Operations. The defined benefit pension
and  postretirement  health  and  life  benefit  expense  (credits)  associated  with  our  other  operations  are  recognized  in  accumulated  other  comprehensive
income.

(a) The expected long-term rates of return used to determine net periodic benefit expense for 2022 have been reduced to 6.00 percent for pension expense and 4.80 percent

to 6.00 percent for postretirement health and life expense.

In establishing the expected long-term rate of return on plan assets, we determine the long-term historical performance of each asset class, adjust these for
current economic conditions, and utilizing the target allocation of our plan assets, forecast the expected long-term rate of return.

The discount rate is computed using a bond matching study which utilizes a portfolio of high quality bonds that produce cash flows similar to the projected
costs of our pension and other postretirement plans.

The Company utilizes actuarial assumptions about mortality to calculate the pension and postretirement health and life benefit obligations. The mortality
assumptions used to calculate our pension and other postretirement benefit obligations as of December 31, 2021, considered a modified PRI-2012 mortality
table and MP-2021 mortality projection scale.

There were no shares of ALLETE common stock included in pension plan equity securities as of December 31, 2021 (no shares as of December 31, 2020).

The defined benefit pension plans have adopted a dynamic asset allocation strategy (glide path) that increases the invested allocation to fixed income assets
as the funding level of the plan increases to better match the sensitivity of the plan’s assets and liabilities to changes in interest rates. This is expected to
reduce  the  volatility  of  reported  pension  plan  expenses.  The  postretirement  health  and  life  plans’  assets  are  diversified  to  achieve  strong  returns  within
managed  risk.  Equity  securities  are  diversified  among  domestic  companies  with  large,  mid  and  small  market  capitalizations,  as  well  as  investments  in
international companies. The majority of debt securities are made up of investment grade bonds.

Fair  value  is  the  price  that  would  be  received  to  sell  an  asset  or  paid  to  transfer  a  liability  in  an  orderly  transaction  between  market  participants  at  the
measurement  date  (exit  price).  We  utilize  market  data  or  assumptions  that  market  participants  would  use  in  pricing  the  asset  or  liability,  including
assumptions  about  risk  and  the  risks  inherent  in  the  inputs  to  the  valuation  technique.  These  inputs  can  be  readily  observable,  market  corroborated,  or
generally  unobservable.  We  primarily  apply  the  market  approach  for  recurring  fair  value  measurements  and  endeavor  to  utilize  the  best  available
information. Accordingly, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. These
inputs, which are used to measure fair value, are prioritized through the fair value hierarchy. The hierarchy gives the highest priority to unadjusted quoted
prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). (See
Note 6. Fair Value.)

Accounting  and  disclosure  requirements  for  the  Medicare  Prescription  Drug,  Improvement  and  Modernization  Act  of  2003  (Act)  provide  guidance  for
employers that sponsor postretirement health care plans that provide prescription drug benefits. We provide a fully insured postretirement health benefit,
including a prescription drug benefit, which qualifies us for a federal subsidy under the Act. The federal subsidy is reflected in the premiums charged to us
by the insurance company.

NOTE 12. EMPLOYEE STOCK AND INCENTIVE PLANS

Employee Stock Ownership Plan. We sponsor an ESOP within the RSOP. Eligible employees may contribute to the RSOP plan as of their date of hire.
The dividends received by the ESOP are distributed to participants. Dividends on allocated ESOP shares are recorded as a reduction of retained earnings.
ESOP employer allocations are funded with contributions paid in either cash or the issuance of ALLETE common stock at the Company’s discretion. We
record  compensation  expense  equal  to  the  cash  or  current  market  price  of  stock  contributed.  ESOP  compensation  expense  was  $11.5  million  in  2021
($11.2 million in 2020; $10.8 million in 2019).

According  to  the  accounting  standards  for  stock  compensation,  unallocated  shares  of  ALLETE  common  stock  held  and  purchased  by  the  ESOP  were
treated as unearned ESOP shares and not considered outstanding for earnings per share computations. All ESOP shares have been allocated to participants
as of December 31, 2021, 2020 and 2019.

Stock-Based Compensation.

Stock Incentive Plan. Under our Executive Long-Term Incentive Compensation Plan (Executive Plan), share-based awards may be issued to key employees
through a broad range of methods, including non-qualified and incentive stock options, performance shares, performance units, restricted stock, restricted
stock units, stock appreciation rights and other awards. There are 0.7 million shares of ALLETE common stock reserved for issuance under the Executive
Plan, of which 0.7 million of these shares remain available for issuance as of December 31, 2021.

NOTE 12. EMPLOYEE STOCK AND INCENTIVE PLANS (Continued)
Stock-Based Compensation (Continued)

The following types of share-based awards were outstanding in 2021, 2020 or 2019:

Performance Shares. Under the performance share awards, the number of shares earned is contingent upon attaining specific market and performance
goals  over  a  three-year  performance  period.  Market  goals  are  measured  by  total  shareholder  return  relative  to  a  group  of  peer  companies  while
performance goals are measured by earnings per share growth. 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 market 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 incorporates the probability of meeting the total shareholder return goals. 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.

Restricted Stock Units. Under the restricted stock unit awards, shares for participants eligible for retirement vest monthly over a three-year period. For
participants not eligible for retirement, shares vest at the end of the three-year period. In the case of qualified retirement, death or disability, a pro rata
portion of the award will be earned. 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 earned. The fair value of these awards is equal to the grant
date fair value. Compensation cost is recognized over the three-year vesting 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; we are not required to apply fair value accounting to these awards as the discount is not greater than 5 percent.

RSOP. The RSOP is a contributory defined contribution plan subject to the provisions of the Employee Retirement Income Security Act of 1974, as
amended, and qualifies as an employee stock ownership plan and profit sharing plan. The RSOP provides eligible employees an opportunity to save for
retirement.

The following share-based compensation expense amounts were recognized in our Consolidated Statement of Income for the periods presented.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are acknowledged hereby, the parties

permanently or indefinitely; provided that, at the time of such statement or publication, there is no successor administrator that will
continue to provide any Available Tenor of such Benchmark (or such component thereof); or

case, in a manner adverse to the Borrower. The Administrative Agent may select information sources or services in its reasonable discretion

number).

Credit Exposure exceeding such Lender’s Commitment. Within the foregoing limits, the Borrower may borrow, prepay and reborrow Loans.

Section 1.2.

Loans and Borrowings.

(a)

Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in accordance with
their respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its
obligations hereunder, provided that the Commitments of the Lenders are several, and no Lender shall be responsible for any other Lender’s
failure to make any Loan as required.

(b)

Subject  to  Section 3.4,  each  Borrowing  shall  be  comprised  entirely  of  ABR  Loans  or  Term  Benchmark  Loans,  as
applicable,  in  each  case  as  the  Borrower  may  request  in  accordance  herewith.  Each  Lender  at  its  option  may  make  any  Term  Benchmark
Loan (and any ABR Loan, the interest on which is determined pursuant to clause (c) of the definition of Alternate Base Rate) by causing any
domestic  or  foreign  branch  or  Affiliate  of  such  Lender  to  make  such  Loan,  provided  that  any  exercise  of  such  option  shall  not  affect  the
obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement.

(c)

At the commencement of each Interest Period for any Term Benchmark Borrowing, such Borrowing shall be in an
aggregate  amount  that  is  $5,000,000  or  a  higher  integral  multiple  of  $1,000,000.  At  the  time  that  each  ABR  Borrowing  is  made,  such
Borrowing shall be in an aggregate amount that is $5,000,000 or a higher integral multiple of $1,000,000, provided that an ABR Borrowing
may be in an aggregate amount that is equal to the entire unused balance of the total Commitments or in an aggregate amount that is required
to  finance  the  reimbursement  of  an  LC  Disbursement  as  contemplated  by  Section  2.9(e).  Borrowings  of  more  than  one  Type  may  be
outstanding at the same time, provided that there shall not at any time be more than a total of ten Term Benchmark Borrowings outstanding.

convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

(d)

Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to

Section 1.3.

Requests for Borrowings.

(a)

To request a Borrowing, the Borrower shall deliver a Credit Request to the Administrative Agent (x) in the case of a
Term Benchmark Borrowing, not later than 12:30 p.m. three Business Days before the date of the proposed Borrowing or (y) in the case of an
ABR Borrowing, not later than 12:30 p.m. on the date of the proposed Borrowing. Each such Credit Request shall be irrevocable (except as
otherwise provided in Section 3.4) and shall specify the following information in compliance with Section 2.2:

(i)

(ii)

the aggregate amount of the requested Borrowing;

the date of such Borrowing, which shall be a Business Day;

(iii)

whether such Borrowing is to be an ABR Borrowing or a Term Benchmark Borrowing;

744315352 11074672    23     ALLETE CREDIT AGREEMENT

(iv)

in the case of a Term Benchmark Borrowing, the initial Interest Period to be applicable thereto, which shall

be a period contemplated by the definition of the term “Interest Period”; and

(v)

the location and number of the Borrower’s account to which funds are to be disbursed, which shall comply

with the requirements of Section 2.4.

(b)

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If
no Interest Period is specified with respect to any requested Term Benchmark Borrowing, then the Borrower shall be deemed to have selected
an  Interest  Period  of  one  month’s  duration.  Promptly  following  receipt  of  a  Credit  Request  in  accordance  with  this  Section,  the
Administrative  Agent  shall  advise  each  Lender  of  the  details  thereof  and  of  the  amount  of  such  Lender’s  Loan  to  be  made  as  part  of  the
requested Borrowing.

Section 1.4.

Funding of Borrowings.

(a)

Each  Lender  shall  make  each  Loan  to  be  made  by  it  hereunder  on  the  proposed  date  thereof  by  wire  transfer  of
immediately  available  funds  by  2:00  p.m.  to  the  account  of  the  Administrative  Agent  most  recently  designated  by  it  for  such  purpose  by
notice to the Lenders. Subject to Section 5.2, the Administrative Agent will make such Loans available to the Borrower by promptly crediting
or otherwise transferring the amounts so received, in like funds, to an account of the Borrower designated by the Borrower in the applicable
Credit Request, provided that ABR Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.9(e) shall be
remitted by the Administrative Agent to the applicable Issuing Bank.

(b)

Unless  the  Administrative  Agent  shall  have  received  notice  from  a  Lender  prior  to  the  proposed  date  of  any
Borrowing (or purchase of participations pursuant to Section 2.9(e)) that such Lender will not make available to the Administrative Agent
such Lender’s share of such Borrowing (or the amount of its participation), the Administrative Agent may assume that such Lender has made
such  share  available  on  such  date  in  accordance  with  Section 2.4(a)  or  Section  2.9(e)  and  may,  in  reliance  upon  such  assumption,  make
available to the Borrower or the applicable Issuing Bank, as applicable, a corresponding amount. In such event, if a Lender has not in fact
made  its  share  of  the  applicable  Borrowing  available  to  the  Administrative  Agent,  then  the  applicable  Lender  and  the  Borrower  (and,  if
applicable, the applicable Issuing Bank) severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount
with  interest  thereon,  for  each  day  from  and  including  the  date  such  amount  is  made  available  to  the  Borrower  or  such  Issuing  Bank,  as
applicable, to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender or an Issuing Bank, the greater
of  the  Federal  Funds  Effective  Rate  and  a  rate  determined  by  the  Administrative  Agent  in  accordance  with  banking  industry  rules  on
interbank compensation or (ii) in the case of the Borrower, the interest rate that would be otherwise applicable to such Borrowing (or such
participating  interest).  Any  payment  by  the  Borrower  or  an  Issuing  Bank,  however,  shall  be  without  prejudice  to  its  rights  against  the
applicable  Lender.  If  such  Lender  pays  such  amount  to  the  Administrative  Agent,  then  such  amount  shall  constitute  such  Lender’s  Loan
included in such Borrowing (or participation in the applicable LC Disbursement).

Section 1.5.

Termination, Reduction and Increase of Commitments.

(a)

Unless previously terminated, the Commitments shall terminate on the Maturity Date. For the avoidance of doubt,
the  Commitment  of  the  Second  Amendment  Declining  Lender  shall  terminate  on  the  Initial  Maturity  Date  and  the  total  Commitments
hereunder shall be reduced by the Commitment of the Second Amendment Declining Lender so terminated on such date except to the extent
that the Borrower has required the Second Amendment Declining Lender to assign its rights under this Agreement to one or more Eligible
Assignees that have agreed to extend their respective Commitments to terminate on the Maturity Date in accordance with Section 2.8.

744315352 11074672    24     ALLETE CREDIT AGREEMENT

(b)

The Borrower may at any time terminate, or from time to time reduce, the Commitments, provided that the Borrower
shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment or repayment of the Loans in accordance
with Section 2.7, the sum of the Credit Exposures would exceed the total Commitments and each such reduction of the Commitments shall be
in the amount of $5,000,000 or a higher integral multiple of $1,000,000.

(c)

The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under
paragraph (b) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election
and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents
thereof. Each  notice  delivered  by  the  Borrower  pursuant  to  this  Section  shall  be  irrevocable,  provided  that  a  notice  of  termination  of  the
Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which
case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such
condition  is  not  satisfied.  Each  reduction,  and  any  termination,  of  the  Commitments  shall  be  permanent  and  each  reduction  of  the
Commitments shall be made ratably among the Lenders in accordance with their respective Commitments.

(d)

The Borrower may at any time and from time to time prior to the Maturity Date, at its sole cost, expense and effort,
request any one or more of the Lenders to increase its Commitment (the decision to increase the Commitment of a Lender to be within the
sole and absolute discretion of such Lender), or any other Person reasonably satisfactory to the Administrative Agent and the Issuing Banks
to provide a new Commitment, by submitting to the Administrative Agent and the Issuing Banks an Increase Supplement duly executed by
the  Borrower  and  each  such  Lender  or  other  Person,  as  the  case  may  be,  together  with  such  other  documentation  and  deliveries  as  the
Administrative Agent shall reasonably require (which may include copies of resolutions authorizing such increase and/or opinion of counsel).
If such Increase Supplement is in all respects reasonably satisfactory to the Administrative Agent and the Issuing Banks, the Administrative
Agent  shall  execute  such  Increase  Supplement  and  the  Administrative  Agent  shall  deliver  a  copy  thereof  to  the  Borrower  and  each  such
Lender or other Person, as the case may be. Upon execution and delivery of such Increase Supplement by the Administrative Agent and the
Issuing Banks, (i) in the case of each such Lender (an “Increasing Lender”), its Commitment shall be increased to the amount set forth in
such Increase Supplement, (ii) in the case of each such other Person (a “New Lender”), such New Lender shall become a party hereto and
have the rights and obligations of a Lender under the Loan Documents and its Commitment shall be as set forth in such Increase Supplement;
provided that:

(A)

immediately  after  giving  effect  thereto,  the  sum  of  all  increases  (other  than  any  increase  in  any  Lender’s
Commitment in order to replace another Lender pursuant to Section 3.8(b)) in the aggregate Commitments made pursuant to
this Section 2.5(d) shall not exceed the sum of (x) $150,000,000 plus (y) the amount of the Commitment of each Lender that
becomes a Defaulting Lender;

(B)

each  such  increase  of  the  aggregate  Commitments  shall  be  in  an  amount  not  less  than  $10,000,000  or  a

higher integral multiple of $5,000,000;

(C)

if  Loans  would  be  outstanding  immediately  after  giving  effect  to  any  such  increase,  then  simultaneously
with such increase (1) each such Increasing Lender, each New Lender and each other Lender shall be deemed to have entered
into an Assignment and Assumption, pursuant to which each such other Lender shall have assigned to each such Increasing
Lender and each such New Lender a portion of its Commitment, Loans and LC Exposure necessary to reflect proportionately
the Commitments as adjusted in accordance with this paragraph (d), and (2) in connection with such assignment, each such
Increasing  Lender  and  each  such  New  Lender  shall  pay  to  the  Administrative  Agent,  for  the  account  of  each  such  other
Lender,  such  amount  as  shall  be  necessary  to  reflect  the  assignment  to  it  of  Loans,  and  in  connection  with  such  master
assignment each such other Lender may treat the

assignment of Term Benchmark Borrowings as a prepayment of such Term Benchmark Borrowings for purposes of Section
3.6;

certificate of a Financial Officer demonstrating pro forma compliance with the terms of this Agreement through the Maturity
Date  and  the  Administrative  Agent  shall  have  received  such  certificates  and  other  items  as  it  shall  reasonably  request  in
connection with such increase.

Section 1.6.

applicable Issuing Bank) with respect to the outstanding Letters of Credit as shall be required such that, after giving effect to the termination
of  the  Commitment  of  the  Second  Amendment  Declining  Lender  pursuant  to  Section  2.5(a),  the  aggregate  Credit  Exposure  less  the  face
amount of any Letter of Credit supported by any such cash collateral (or other satisfactory arrangements) so provided does not exceed the
aggregate amount of Commitments after giving effect to such Commitment termination.

Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the debt of the
Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to
such Lender from time to time hereunder.

account of the Lenders and each Lender’s share thereof.

(d)

The  entries  made  in  the  accounts  maintained  pursuant  to  paragraph (b)  or  (c)  of  this  Section  shall  be  prima  facie
evidence  of  the  existence  and  amounts  of  the  obligations  recorded  therein,  provided  that  the  failure  of  any  Lender  or  the  Administrative
Agent  to  maintain  such  accounts  or  any  error  therein  shall  not  in  any  manner  affect  the  obligation  of  the  Borrower  to  repay  the  Loans  in
accordance with the terms of this Agreement.

(e)

Any Lender may request that its Loans be evidenced by a Note. In such event, the Borrower shall prepare, execute
and deliver to such Lender a Note payable to the order of such Lender. Thereafter, the Loans evidenced by such Note and interest thereon
shall at all times (including after any assignment pursuant to Section 10.4) be represented by a Note payable to the order of the payee named
therein or any Eligible Assignee pursuant to Section 10.4, except to the extent that any such Lender or Eligible Assignee subsequently returns
any such Note for cancellation and requests that such Loans once again be evidenced as described in paragraphs (b) and (c) above.

Section 1.7.

Prepayment of Loans.

Borrowing in whole or in part, subject to the requirements of this Section.

(a)

Voluntary  Prepayments.  The  Borrower  shall  have  the  right  at  any  time  and  from  time  to  time  to  prepay  any

744315352 11074672    26     ALLETE CREDIT AGREEMENT

(b)

Prepayments  Resulting  from  the  Reduction  of  the  Total  Commitments.  In  the  event  of  any  partial  reduction  or
termination  of  the  Commitments,  then  at  or  prior  to  the  date  of  such  reduction  or  termination,  the  Administrative  Agent  shall  notify  the
Borrower  and  the  Lenders  of  the  sum  of  the  Credit  Exposures  after  giving  effect  thereto  and  if  such  sum  would  exceed  the  total
Commitments  after  giving  effect  to  such  reduction  or  termination,  then  the  Borrower  shall,  on  the  date  of  such  reduction  or  termination,
prepay Borrowings in an amount sufficient to eliminate such excess.

(c)

Notice  of  Prepayment;  Application  of  Prepayments.  The  Borrower  shall  notify  the  Administrative  Agent  by
telephone (confirmed by facsimile) of any prepayment hereunder, (i) in the case of a prepayment of a Term Benchmark Borrowing, not later
than 11:30 a.m. three Business Days before the date of prepayment or (ii) in the case of prepayment of an ABR Borrowing, not later than
11:30  a.m.  on  the  date  of  the  prepayment.  Each  such  notice  shall  be  irrevocable  and  shall  specify  the  prepayment  date  and  the  principal
amount of each Borrowing or portion thereof to be prepaid, provided that, if a notice of prepayment is given in connection with a conditional
notice of termination of the Commitments as contemplated by Section 2.5, then such notice of prepayment may be revoked if such notice of
termination  is  revoked  in  accordance  with  Section  2.5.  Promptly  following  receipt  of  any  such  notice  relating  to  a  Borrowing,  the
Administrative  Agent  shall  advise  the  Lenders  of  the  contents  thereof.  Each  partial  prepayment  of  any  Borrowing  shall  be  in  an  integral
multiple of $1,000,000 and not less than $5,000,000 (or, if the outstanding principal balance of the applicable Borrowing is less than such
minimum amount, then such lesser outstanding principal balance); provided that if, as a result of any ABR Borrowing to reimburse an LC
Disbursement pursuant to Section 2.9(e), the aggregate principal amount of all ABR Borrowings is not an integral multiple of $1,000,000,
then any prepayment of ABR Borrowings shall be in an amount that will cause the aggregate principal amount of all ABR Borrowings to be
an integral multiple of $1,000,000. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing.
Prepayments  shall  be  accompanied  by  accrued  interest  to  the  extent  required  by  Section  3.1  and,  if  applicable,  shall  be  subject  to  the
provisions of Section 3.6. Notwithstanding any provision of this Section 2.7(c) to the contrary, if any Lender becomes a Defaulting Lender,
then the provisions of Section 2.11 shall apply for so long as such Lender is a Defaulting Lender.

Section 1.8.

Extension of Maturity Date.

After November 23, 2021, the Borrower may, on one occasion during the term of this Agreement, request an extension of the
Maturity Date for an additional one-year period by submitting a request for extension (an “Extension Request”) to the Administrative Agent
(which shall promptly advise each Lender) not more than 75 days or less than 30 days prior to the effective date of the proposed extension
(the “Extension  Effective  Date”). In  response  to  such  request,  each  Lender  shall,  not  later  than  20  days  prior  to  the  applicable  Extension
Effective Date, notify the Administrative Agent whether it is willing (in its sole and complete discretion) to extend the scheduled Maturity
Date for an additional one-year period (and any Lender that fails to give such notice to the Administrative Agent shall be deemed to have
elected not to extend the scheduled Maturity Date). The Administrative Agent will notify the Borrower of the Lenders’ decisions no later
than 15 days prior to such Extension Effective Date. If Lenders holding more than 50% of the Commitments elect to extend the scheduled
Maturity Date, then on such Extension Effective Date the Commitments of such Lenders shall be extended for an additional one-year period;
provided that (i) no Default exists on such Extension Effective Date and (ii) all representations and warranties are true and correct on such
Extension Effective Date, as though made as of such Extension Effective Date (or, if any such representation or warranty is expressly stated
to have been made as of a specific date, as of such specific date). No Lender shall be required to consent to any Extension Request and any
Lender that elects, or is deemed to have elected, not to extend the scheduled Maturity Date (a “Declining Lender”) will have its Commitment
terminated on the then existing scheduled Maturity Date (without regard to any extension by other Lenders). The Borrower may, at its sole
expense and effort, upon notice to any Declining Lender and the Administrative Agent, require any Declining Lender to assign and delegate
its rights and obligations under this Agreement to an Eligible Assignee selected by the Borrower and willing to accept such assignment (in
accordance with, and subject to, the restrictions and consents otherwise required for assignments generally).

Section 1.9.

Letters of Credit.

(a)

General. Subject to the terms and conditions set forth herein, the Borrower may request the issuance of Letters of
Credit  denominated  in  dollars  as  the  applicant  thereof  for  the  support  of  its  or  its  Subsidiaries’  obligations,  in  a  form  acceptable  to  the
Administrative Agent and the applicable Issuing Bank, at any time and from time to time during the period from the Effective Date to the
tenth Business Day preceding the last day of the Availability Period; provided that (i) the aggregate amount of the Credit Exposure of all
Lenders shall not exceed the total Commitments and (ii) the aggregate amount of all LC Exposure shall not at any time exceed $100,000,000.
In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of
credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, an Issuing Bank relating to any
Letter of Credit, the terms and conditions of this Agreement shall control.

(b)

Notice  of  Issuance;  Amendment;  Renewal;  Extension;  Certain  Conditions.  To  request  the  issuance  of  a  Letter  of
Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or facsimile (or transmit
by electronic communication, pursuant to arrangements for doing so approved by the applicable Issuing Bank) to the applicable Issuing Bank
and the Administrative Agent (not later than three Business Days before the requested date of issuance, amendment, renewal or extension) a
Credit Request  requesting  the  issuance  of  a  Letter  of  Credit,  or  identifying  the  Letter  of  Credit  to  be  amended,  renewed  or  extended,  and
specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is
to  expire  (which  shall  comply  with  paragraph  (c)  of  this  Section),  the  amount  of  such  Letter  of  Credit,  the  name  and  address  of  the
beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by
an Issuing Bank, the Borrower also shall submit a letter of credit application on such Issuing Bank’s standard form in connection with any
request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and, upon issuance, amendment,
renewal  or  extension  of  each  Letter  of  Credit,  the  Borrower  shall  be  deemed  to  represent  and  warrant  that),  after  giving  effect  to  such
issuance, amendment, renewal or extension, (i) (x) the aggregate undrawn amount of all outstanding Letters of Credit issued by the Issuing
Bank at such time plus (y) the aggregate amount of all LC Disbursements made by the Issuing Bank that have not yet been reimbursed by or
on  behalf  of  the  Borrower  at  such  time  shall  not  exceed  its  Letter  of  Credit  Commitment,  (ii)  the  LC  Exposure  shall  not  exceed  the  total
Letter of Credit Commitments, (iii) the total Credit Exposures shall not exceed the total Commitments. The Borrower may, at any time and
from time to time, reduce the Letter of Credit Commitment of any Issuing Bank with the consent of such Issuing Bank; provided  that  the
Borrower shall not reduce the Letter of Credit Commitment of any Issuing Bank if, after giving effect of such reduction, the conditions set
forth in clauses (i) and (ii) above shall not be satisfied.

(c)

Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date that
is one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such
renewal or extension), and (ii) the date that is ten Business Days prior to the Maturity Date, provided that any Letter of Credit may provide
for the automatic renewal thereof for any period (unless the applicable Issuing Bank elects not to extend) so long as such period ends at least
ten Business Days prior to the Maturity Date or if the Borrower shall have deposited cash collateral with the Administrative Agent to the
extent required by Section 2.9(j) for such Letter of Credit, not later than the first anniversary of the Maturity Date.

(d)

Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount
thereof) and without any further action on the part of the applicable Issuing Bank or the Lenders, such Issuing Bank hereby grants to each
Lender and each Lender hereby acquires from such Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable
Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing,
each such Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of such Issuing Bank,
such

744315352 11074672    28     ALLETE CREDIT AGREEMENT

Lender’s Applicable Percentage of each LC Disbursement made by such Issuing Bank and not reimbursed by the Borrower on the date due as
provided in paragraph (e) of this Section, or of any reimbursement payment required to be refunded to the Borrower for any reason. Each
such Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is
absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any
Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment
shall be made without any offset, abatement, withholding or reduction whatsoever.

(e)

Reimbursement.  If  any  Issuing  Bank  shall  make  an  LC  Disbursement  in  respect  of  a  Letter  of  Credit,  then  such
Issuing  Bank  shall  promptly  notify  the  Borrower  of  such  LC  Disbursement  and  the  Borrower  shall  reimburse  such  LC  Disbursement  by
paying  to  the  Administrative  Agent,  for  the  account  of  such  Issuing  Bank,  an  amount  equal  to  such  LC  Disbursement  and  any  accrued
interest  thereon  (collectively,  the  “Unreimbursed  Amount”)  by  not  later  than  (i)  if  the  Borrower  shall  have  received  notice  of  such  LC
Disbursement  prior  to  11:00  a.m.  on  such  date,  2:00  p.m.  on  such  date,  or  (ii)  otherwise,  2:00  p.m.  on  the  Business  Day  immediately
following the day that the Borrower receives such notice. If the Borrower fails to reimburse an Issuing Bank in full for an LC Disbursement
prior to the time required pursuant to the preceding sentence, then such Issuing Bank may (and the Borrower authorizes such Issuing Bank
to) request, on behalf of the Borrower by notice to the Administrative Agent (which shall promptly advise each Lender), that the Lenders
fund  an  ABR  Borrowing  in  an  amount  equal  to  the  Unreimbursed  Amount,  without  regard  to  the  minimum  and  integral  multiple
requirements  in  Section  2.2(c),  and  each  Lender  shall  make  its  Loan  as  part  of  such  ABR  Borrowing  (by  wire  transfer  of  immediately
available funds to the account most recently designated by the Administrative Agent for such purpose by notice to the Lenders) not later than
(x) if such Lender shall have received notice of such Borrowing from the Administrative Agent prior to 12:00 noon on such date, 2:00 p.m.
on such date or (y) otherwise, 2:00 p.m. on the Business Day immediately following the day that such Lender receives such notice; provided
that if the conditions precedent to a Borrowing specified in Section 5.2 are not satisfied, then the request by the Issuing Bank shall be deemed
to be a request for the funding of the Lenders’ participations in such Unreimbursed Amount and the amounts made available by the Lenders
to the Administrative Agent as provided above shall constitute the Lenders’ funding of their respective participations in such Unreimbursed
Amount. The Administrative Agent will make the proceeds of such Loans or participations, as applicable, available to the applicable Issuing
Bank by promptly crediting or otherwise transferring the amounts so received, in like funds, to such Issuing Bank for the purpose of repaying
in  full  the  LC  Disbursement  and  all  accrued  interest  thereon.  Any  Lender  that  fails  to  make  the  proceeds  of  its  Loan  or  its  participation
available to the Administrative Agent in accordance with the provisions of this Section 2.9(e) shall pay interest thereon, for the account of the
applicable Issuing Bank, for each day from and including the date such amount is due to but excluding the date such amount is received by
the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance
with banking industry rules on interbank compensation.

(f)

Obligations Absolute. The Borrower’s obligations to reimburse LC Disbursements as provided in paragraph (e)  of
this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement
under any and all circumstances whatsoever and irrespective of any lack of validity or enforceability of any Letter of Credit or any Loan
Document, or any term or provision therein, any draft or other document presented under a Letter of Credit proving to be forged, fraudulent,
insufficient or invalid in any respect or any statement therein being untrue or inaccurate in any respect, payment by any Issuing Bank under a
Letter  of  Credit  against  presentation  of  a  draft  or  other  document  that  does  not  comply  with  the  terms  of  such  Letter  of  Credit,  any
amendment or waiver of or any consent to departure from all or any of the provisions of any Letter of Credit or any Loan Document, the
existence  of  any  claim,  set-off,  defense  or  other  right  that  the  Borrower,  any  other  party  guaranteeing,  or  otherwise  obligated  with,  such
Borrower,  any  Subsidiary  or  other  Affiliate  thereof  or  any  other  Person  may  at  any  time  have  against  the  beneficiary  under  any  Letter  of
Credit, any Credit Party or any other Person, whether in connection with this Agreement, any other Loan Document or any other related or
unrelated agreement or transaction, or any other act or omission to act or delay of any kind of any Credit Party

744315352 11074672    29     ALLETE CREDIT AGREEMENT

or any other Person or any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the
provisions  of  this  Section,  constitute  a  legal  or  equitable  discharge  of,  or  provide  a  right  of  set-off  against,  the  Borrower’s  obligations
hereunder. Neither any Credit Party nor any of their respective Related Parties shall have any liability or responsibility by reason of or in
connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of
any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery
of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing
thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of any Issuing Bank;
provided  that  the  foregoing  shall  not  be  construed  to  excuse  an  Issuing  Bank  from  liability  to  the  Borrower  to  the  extent  of  any  direct
damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by
applicable law) suffered by the Borrower that are caused by any Issuing Bank’s failure to exercise care when determining whether drafts and
other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of
gross  negligence  or  willful  misconduct  on  the  part  of  any  Issuing  Bank  (as  finally  determined  by  a  court  of  competent  jurisdiction),  such
Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the
generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with
the terms of a Letter of Credit, any Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without
responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon
such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g)

Disbursement Procedures. Each  Issuing  Bank  shall,  promptly  following  its  receipt  thereof,  examine  all  documents
purporting to represent a demand for payment under a Letter of Credit. Each Issuing Bank shall promptly notify the Administrative Agent
and the Borrower by telephone (confirmed by telecopy or electronic mail) of such demand for payment and whether the Issuing Bank has
made  or  will  make  an  LC  Disbursement  thereunder;  provided  that  any  failure  to  give  or  delay  in  giving  such  notice  shall  not  relieve  the
Borrower of its obligation to reimburse the applicable Issuing Bank and the Lenders with respect to any such LC Disbursement.

(h)

Interim Interest. If  any  Issuing  Bank  shall  make  any  LC  Disbursement,  then,  unless  the  Borrower  shall  reimburse
such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from
and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the
rate per annum then applicable to ABR Loans; provided that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to
paragraph  (e)  of  this  Section,  then  Section  3.1(b)  shall  apply.  Interest  accrued  pursuant  to  this  paragraph  shall  be  for  the  account  of  the
applicable Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (e) of this Section
to reimburse the applicable Issuing Bank shall be for the account of such Lender to the extent of such payment.

(i)

Replacement  and  Resignation  of  an  Issuing  Bank.  (i)  An  Issuing  Bank  may  be  replaced  at  any  time  by  written
agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative
Agent shall notify the Lenders of any such replacement of an Issuing Bank. At the time any such replacement shall become effective, the
Borrower  shall  pay  all  unpaid  fees  accrued  for  the  account  of  the  replaced  Issuing  Bank  pursuant  to  Section  3.3(b).  From  and  after  the
effective date of any such replacement, (x) the successor Issuing Bank shall have all the rights and obligations of Issuing Banks under this
Agreement with respect to Letters of Credit to be issued thereafter and (y) references herein to the term “Issuing Bank” shall be deemed to
refer to such successor or to any previous Issuing Banks, or to such successor and all previous Issuing Banks, as the context shall require.
After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the
rights and obligations of an Issuing Bank under this Agreement with respect to Letters of

744315352 11074672    30     ALLETE CREDIT AGREEMENT

Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

(ii) Subject to the appointment and acceptance of a successor Issuing Bank, any Issuing Bank may resign as an Issuing Bank
at  any  time  upon  30  days’  prior  written  notice  to  the  Administrative  Agent,  the  Borrower  and  the  Lenders,  in  which  case,  such
resigning Issuing Bank shall be replaced in accordance with Section 2.9(i) above.

(j)

Cash Collateral. In the event that (i) an Event of Default shall occur and be continuing or (ii) any Letter of Credit has
an expiry date on or after the tenth Business Day prior to the Maturity Date (or any LC Disbursements remain unreimbursed on or after such
date), the Borrower shall deposit with the Administrative Agent in immediately available funds on the Business Day on which it receives
notice from the Administrative Agent or Required Lenders demanding the deposit of cash collateral in the case of clause (i), or no later than
the tenth Business Day prior to the Maturity Date in the case of clause (ii), an amount equal to the Required Deposit Amount, which amount
shall be held by the Administrative Agent for the benefit of the Lenders as cash collateral pursuant to a cash collateral agreement in form and
substance satisfactory to the Administrative Agent and the applicable Issuing Banks to secure the Borrower’s reimbursement obligations with
respect  to  LC  Disbursements;  provided  that  the  obligation  to  deposit  such  cash  collateral  shall  become  effective  immediately,  and  such
deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default
described  in  paragraph  (i)  or  (j)  of  Article  8.  Such  deposit  shall  be  held  by  the  Administrative  Agent  as  collateral  for  the  payment  and
performance of the obligations of the Borrower under this Agreement. The Administrative Agent shall have exclusive dominion and control,
including the exclusive right of withdrawal, over such account. Such deposit shall not bear interest, nor shall the Administrative Agent be
under  any  obligation  whatsoever  to  invest  the  same,  provided  that,  at  the  request  of  the  Borrower,  such  deposit  shall  be  invested  by  the
Administrative Agent in direct short term obligations of, or short term obligations the principal of and interest on which are unconditionally
guaranteed by, the United States of America, in each case maturing no later than the expiry date of the Letter of Credit giving rise to the
relevant LC Exposure. Interest  or  profits,  if  any,  on  such  investments  shall  accumulate  in  such  account.  Moneys  in  such  account  shall  be
applied by the Administrative Agent to reimburse the applicable Issuing Bank for LC Disbursements for which it has not been reimbursed
and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at
such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Required Lenders), be applied to satisfy other
obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of
the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three
Business Days after all Events of Default have been cured or waived. If the Borrower is required to provide cash collateral hereunder as a
result of clause (ii) of the first sentence of this paragraph, the amount thereof (to the extent not applied as aforesaid) shall be returned to the
Borrower when the LC Exposure is zero and all applicable Letters of Credit shall have been returned to the applicable Issuing Banks and
shall have been cancelled.

the provisions of Section 2.11 shall apply for so long as such Lender is a Defaulting Lender.

(k)

Notwithstanding any provision of this Section 2.9 to the contrary, if any Lender becomes a Defaulting Lender, then

Section 1.10.

Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a)

The  Borrower  shall  make  each  payment  required  to  be  made  by  it  hereunder  or  under  any  other  Loan  Document
(whether of principal of Loans, LC Disbursements, interest or fees, or of amounts payable under Sections 3.5, 3.6, 3.7 or 10.3, or otherwise)
prior to 1:00 p.m. on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such
time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day
for purposes of calculating interest thereon. All  such  payments  shall  be  made  to  the  Administrative  Agent  at  its  office  at  10  S.  Dearborn,
Chicago, Illinois, or such other office as to which the Administrative Agent may notify the other parties hereto,

744315352 11074672    31     ALLETE CREDIT AGREEMENT

except that payments pursuant to Sections 3.3(b) (with respect to the fronting fee and other amounts payable to the Issuing Banks), 3.3(c),
3.5, 3.6, 3.7  and  10.3  shall  be  made  directly  to  the  Persons  entitled  thereto.  The  Administrative  Agent  shall  distribute  any  such  payments
received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder
shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case
of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in
dollars.

(b)

Each Borrowing, each payment or prepayment of principal of any Borrowing, each payment of interest on the Loans,
each payment of fees, each reduction of the Commitments and each conversion of any Borrowing to or continuation of any Borrowing as a
Borrowing of any Type shall be allocated pro rata among the Lenders in accordance with their respective applicable Commitments (or, if
such Commitments shall have expired or been terminated, in accordance with the respective principal amounts of their outstanding Loans).
Each Lender agrees that in computing such Lender’s portion of any Borrowing to be made hereunder, the Administrative Agent may, in its
discretion, round each Lender’s percentage of such Borrowing to the next higher or lower whole dollar amount. If at any time insufficient
funds  are  received  by  and  available  to  the  Administrative  Agent  to  pay  fully  all  amounts  of  principal  of  Loans,  unreimbursed  LC
Disbursements, interest, fees and commissions then due hereunder, such funds shall be applied first, towards payment of interest, fees and
commissions then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest, fees and commissions
then due to such parties and second, towards payment of principal of Loans and unreimbursed LC Disbursements then due hereunder, ratably
among the parties entitled thereto in accordance with the amounts of principal of Loans and unreimbursed LC Disbursements then due to
such parties.

(c)

If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any
principal of, or interest on, any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater
proportion  of  the  aggregate  amount  of  its  Loans  and  participations  in  LC  Disbursements  and  accrued  interest  thereon  than  the  proportion
received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the
Loans  and  participations  in  LC  Disbursements  of  other  Lenders  to  the  extent  necessary  so  that  the  benefit  of  all  such  payments  shall  be
shared by the Lenders ratably in accordance with the aggregate amount of principal of, and accrued interest on, their respective Loans and
participations in LC Disbursements, provided that if any such participations are purchased and all or any portion of the payment giving rise
thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and
the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the
express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any
of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate
thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may
effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against
the  Borrower  rights  of  set-off  and  counterclaim  with  respect  to  such  participation  as  fully  as  if  such  Lender  were  a  direct  creditor  of  the
Borrower in the amount of such participation.

(d)

Unless  the  Administrative  Agent  shall  have  received  notice  from  the  Borrower  prior  to  the  date  on  which  any
payment is due to the Administrative Agent for the account of the applicable Credit Parties hereunder that the Borrower will not make such
payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in
reliance upon such assumption, distribute to such Credit Parties the amount due. In such event, if the Borrower has not in fact made such
payment, then each such Credit Party severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to
such Credit Party with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of
payment to the Administrative Agent, at the

744315352 11074672    32     ALLETE CREDIT AGREEMENT

greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on
interbank compensation.

(e)

If any Credit Party shall fail to make any payment required to be made by it pursuant to Section 2.4(b) or 2.10(d),
then  the  Administrative  Agent  may,  in  its  discretion  (notwithstanding  any  contrary  provision  hereof),  (i)  apply  any  amounts  thereafter
received by the Administrative Agent for the account of such Credit Party to satisfy such Credit Party’s obligations under such Sections until
all such unsatisfied obligations are fully paid and (ii) hold any such amounts in a segregated account as cash collateral for, and application to,
any future funding obligations of such Lender under such Sections; in the case of each of (i) and (ii) above, in any order as determined by the
Administrative  Agent  in  its  discretion.  Notwithstanding  any  provision  of  this  Section  2.10  to  the  contrary,  if  any  Lender  becomes  a
Defaulting Lender, then the provisions of Section 2.11 shall apply for so long as such Lender is a Defaulting Lender.

Section  1.11. Defaulting  Lenders.  Notwithstanding  any  provision  of  this  Agreement  to  the  contrary,  if  any  Lender  becomes  a

Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

Lender.

(a)

Fees pursuant to Section 3.3(a) shall cease to accrue on the unfunded portion of the Commitment of such Defaulting

(b)

If any LC Exposure exists at the time a Lender becomes a Defaulting Lender then:

(i)

All or any part of such LC Exposure shall be reallocated among the non-Defaulting Lenders in accordance
with  their  respective  Applicable  Percentages  but  only  to  the  extent  (x)  the  sum  of  all  non-Defaulting  Lenders’  Credit
Exposures  plus  such  Defaulting  Lender’s  LC  Exposure  does  not  exceed  the  total  of  all  non-Defaulting  Lenders’
Commitments and (y) the conditions set forth in Section 5.2 are satisfied at such time;

(ii)

If the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall
within  two  Business  Days  following  notice  by  the  Administrative  Agent  cash  collateralize  such  Defaulting  Lender’s  LC
Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set
forth in Section 2.9(j) for so long as such LC Exposure is outstanding;

(iii)

If  the  Borrower  cash  collateralizes  any  portion  of  such  Defaulting  Lender’s  LC  Exposure  pursuant  to  this
Section 2.11(b), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 3.3(b) with
respect  to  such  Defaulting  Lender’s  LC  Exposure  during  the  period  such  Defaulting  Lender’s  LC  Exposure  is  cash
collateralized;

(iv)

If the LC Exposure of the non-Defaulting Lenders is reallocated pursuant to this Section 2.11(b),  then  the
fees payable to the Lenders pursuant to Sections 3.3(a) and 3.3(b) shall be adjusted in accordance with such non-Defaulting
Lenders’ Applicable Percentages;

(v)

If  any  Defaulting  Lender’s  LC  Exposure  is  neither  cash  collateralized  nor  reallocated  pursuant  to  this
Section 2.11(b), then, without prejudice to any rights or remedies of the Issuing Banks or any Lender hereunder, all letter of
credit  fees  payable  under  Section  3.3(b)  with  respect  to  such  Defaulting  Lender’s  LC  Exposure  shall  be  payable  to  the
applicable Issuing Banks until such LC Exposure is cash collateralized and/or reallocated; and

744315352 11074672    33     ALLETE CREDIT AGREEMENT

(vi)

If and so long as any Lender is a Defaulting Lender, no Issuing Bank shall be required to issue, amend or
increase any Letter of Credit, unless it is satisfied that the related exposure will be 100% covered by the Commitments of the
non-Defaulting  Lenders  or  cash  collateral  will  be  provided  by  the  Borrower  in  accordance  with  this  Section  2.11(b),  and
participating  interests  in  any  such  newly  issued  or  increased  Letter  of  Credit  shall  be  allocated  among  non-Defaulting
Lenders in a manner consistent with Section 2.11(b)(i) (and Defaulting Lenders shall not participate therein).

(c)

The Commitments and Credit Exposure of such Defaulting Lender shall not be included in determining whether all
Lenders  or  the  Required  Lenders  have  voted  or  taken  or  may  take  any  action  hereunder  (including  any  consent  to  any  amendment,
modification  or  waiver  pursuant  to  Section  10.2);  provided  that  (i)  any  waiver,  amendment  or  modification  requiring  the  consent  of  all
Lenders or each affected Lender which affects such Defaulting Lender differently than other affected Lenders shall require the consent of
such  Defaulting  Lender  and  (ii)  any  amendment  or  modification  that  increases,  or  extends  the  maturity  of,  such  Defaulting  Lender’s
Commitment or reduces the principal amount of, or rate of interest on, any Loan made by such Defaulting Lender, shall require the consent
of such Defaulting Lender.

(d)

In the event that the Administrative Agent, the Borrower and each Issuing Bank agree that a Defaulting Lender has
adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the LC Exposure of the Lenders shall be readjusted
to reflect the inclusion of such Lender’s Commitments and on such date such Lender shall purchase at par such of the Loans of the other
Lenders as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its
Applicable Percentage, and all cash collateral and accrued interest thereon held by the Administrative Agent or the applicable Issuing Banks
shall be returned to the Borrower forthwith.

Article 3.

INTEREST, FEES, YIELD PROTECTION, ETC.

Section 1.1.

The  Loans  comprising  each  ABR  Borrowing  shall  bear  interest  at  the  Alternate  Base  Rate  plus  the  Applicable
Margin. The Loans comprising each Term Benchmark Borrowing shall bear interest at the Adjusted Term SOFR Rate for the Interest Period
in effect for such Borrowing plus the Applicable Margin.

(a)

(b)

Notwithstanding the foregoing, if any principal of or interest on any Loan, any reimbursement obligation in respect
of any LC Disbursement or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity,
upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to in the
case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding paragraph of this
Section or in the case of any other amount, 2% plus the rate applicable to ABR Borrowings as provided in the preceding paragraph of this
Section.

(c)

Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan, provided
that interest accrued pursuant to paragraph (b) of this Section shall be payable on demand, in the event of any repayment or prepayment of
any Loan, accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment, and in
the event of any conversion of any Term Benchmark Loan prior to the end of the current Interest Period therefor, accrued interest on such
Loan shall be payable on the effective date of such conversion.

(d)

All  interest  hereunder  shall  be  computed  on  the  basis  of  a  year  of  360  days,  except  that  interest  computed  by
reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a
year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day
but  excluding  the  last  day).  The  applicable  Alternate  Base  Rate,  Adjusted  Daily  Simple  SOFR  or  Adjusted  Term  SOFR  Rate  shall  be
determined by the Administrative Agent, and such determination shall be conclusive absent clearly demonstrable error. The Administrative
Agent shall, as soon as practicable, notify the Borrower and the Lenders of the effective date and the amount of each change in the Prime
Rate or ABR, but any failure to so notify shall not in any manner affect the obligation of the Borrower to pay interest on the Loans in the
amounts and on the dates required.

Section 1.2.

Interest Elections Relating to Borrowings.

(a)

Each Borrowing initially shall be of the Type specified in the applicable Credit Request and, in the case of a Term
Benchmark Borrowing, shall have an initial Interest Period as specified in such Credit Request. Thereafter, the Borrower may elect to convert
such  Borrowing  to  a  different  Type  or  to  continue  such  Borrowing  and,  in  the  case  of  a  Term  Benchmark  Borrowing,  may  elect  Interest
Periods therefor, all as provided in this Section. The Borrower may elect different options with respect to different portions of the affected
Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and
the Loans comprising each such portion shall be considered a separate Borrowing.

To  make  an  election  pursuant  to  this  Section,  the  Borrower  shall  deliver  to  the  Administrative  Agent  a  signed
Interest Election Request in a form approved by the Administrative Agent by the time that a Credit Request would be required under Section
2.3 if the Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election.

(b)

(c)
specify the following information:

Each  such  Interest  Election  Request  shall  be  irrevocable  (except  as  otherwise  provided  in  Section  3.4)  and  shall

(i)

the  Borrowing  to  which  such  Interest  Election  Request  applies  and,  if  different  options  are  being  elected
with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the
information  to  be  specified  pursuant  to  clauses  (iii)  and  (iv)  of  this  paragraph  shall  be  specified  for  each  resulting
Borrowing);

(ii)

the effective date of the election made pursuant to such Interest Election Request, which shall be a Business

Day;

(iii)

whether the resulting Borrowing is to be an ABR Borrowing or a Term Benchmark Borrowing; and

(iv)

if the resulting Borrowing is a Term Benchmark Borrowing, the Interest Period to be applicable thereto after

giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

If any such Interest Election Request requests a Term Benchmark Borrowing but does not specify an Interest Period, then the Borrower shall
be deemed to have selected an Interest Period of one month’s duration.

details thereof and of such Lender’s portion of each resulting Borrowing.

(d)

Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the

744315352 11074672    35     ALLETE CREDIT AGREEMENT

(e)

If the Borrower fails to deliver a timely Interest Election Request prior to the end of the Interest Period applicable
thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period, such Borrowing shall be converted to an
ABR  Borrowing.  Notwithstanding  any  contrary  provision  hereof,  if  an  Event  of  Default  has  occurred  and  is  continuing  and  the
Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing, (i)
no outstanding Borrowing may be converted to or continued as a Term Benchmark Borrowing and (ii) unless repaid, each Term Benchmark
Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

Section 1.3.

Fees.

(a)

The Borrower agrees to pay to the Administrative Agent for the account of each Lender, a facility fee, which shall
accrue  at  a  rate  per annum  equal  to  the  Applicable  Margin  on  the  daily  amount  of  the  Commitment  of  such  Lender  (regardless  of  usage)
during the period from and including the date on which this Agreement becomes effective pursuant to Section 10.6 to but excluding the date
on  which  such  Commitment  terminates;  provided  that,  if  such  Lender  continues  to  have  any  Credit  Exposure  after  its  Commitment
terminates, then such facility fee shall continue to accrue on the daily amount of such Lender’s Credit Exposure from and including the date
on  which  such  Lender’s  Commitment  terminates  to  but  excluding  the  date  on  which  such  Lender  ceases  to  have  any  Credit  Exposure.
Accrued facility fees shall be payable in arrears on the last day of March, June, September and December of each year, each date on which
the Commitments are permanently reduced and on the date on which the Commitments terminate, commencing on the first such date to occur
after the Effective Date, provided that all unpaid facility fees shall be payable on the date on which the Commitments terminate and provided
further that facility fees which accrue after the Commitments terminate shall be payable on demand. All facility fees shall be computed on
the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(b)

The  Borrower  agrees  to  pay  to  the  Administrative  Agent  for  the  account  of  each  Lender  a  participation  fee  with
respect to its participations in Letters of Credit, which shall accrue at a rate per annum equal to the Applicable Margin on the average daily
amount  of  such  Lender’s  LC  Exposure  (excluding  any  portion  thereof  attributable  to  unreimbursed  LC  Disbursements)  during  the  period
from and including the Effective Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on
which such Lender ceases to have any LC Exposure and to each Issuing Bank for its own account a fronting fee, which shall accrue at the
rate  or  rates  per  annum  separately  agreed  upon  between  the  Borrower  and  each  Issuing  Bank  on  the  average  daily  amount  of  the  LC
Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective
Date to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure, as
well as each Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing
of drawings thereunder. Accrued participation fees and fronting fees shall be payable in arrears on the last day of March, June, September
and December of each year, commencing on the first such date to occur after the Effective Date; provided that all such fees shall be payable
on the date on which the Commitments terminate and any such fees accruing after the date on which the Commitments terminate shall be
payable on demand. Any other fees payable to any Issuing Bank pursuant to this paragraph shall be payable within ten days after demand. All
participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days
elapsed (including the first day but excluding the last day).

and at the times separately agreed upon in writing between the Borrower and such Credit Party.

(c)

The Borrower agrees to pay to each Credit Party, for its own account, fees and other amounts payable in the amounts

and other amounts paid shall not be refundable under any circumstances other than clearly demonstrable error.

(d)

All fees and other amounts payable hereunder shall be paid on the dates due, in immediately available funds. Fees

Section 1.4.

Alternate Rate of Interest.

(a)

Subject to clauses (b), (c), (d), (e) and (f) of this Section 3.4, if:

(i)

the Administrative Agent determines (which determination shall be conclusive absent manifest error) prior
to the commencement of any Interest Period for a Term Benchmark Borrowing, that adequate and reasonable means do not
exist  for  ascertaining  the  Adjusted  Term  SOFR  Rate  or  the  Term  SOFR  Rate,  as  applicable  (including,  because  the  Term
SOFR Reference Rate is not available or published on a current basis) for such Interest Period; or

(ii)

the Administrative Agent is advised by the Required Lenders that prior to the commencement of any Interest
Period for a Term Benchmark Borrowing, the Adjusted Term SOFR Rate for such Interest Period will not adequately and
fairly  reflect  the  cost  to  such  Lenders  (or  Lender)  of  making  or  maintaining  their  Loans  (or  Loan)  included  in  such
Borrowing for such Interest Period;

then  the  Administrative  Agent  shall  give  notice  thereof  to  the  Borrower  and  the  Lenders  by  telephone,  telecopy,  electronic  mail  or  other
electronic system as promptly as practicable thereafter and, until (x) the Administrative Agent notifies the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist with respect to the relevant Benchmark and (y) the Borrower delivers a new Interest
Election Request in accordance with the terms of Section 3.2 or a new Credit Request in accordance with the terms of Section 2.3, (1) any
Interest  Election  Request  that  requests  the  conversion  of  any  Borrowing  to,  or  continuation  of  any  Borrowing  as,  a  Term  Benchmark
Borrowing and any Credit Request that requests a Term Benchmark Borrowing shall instead be deemed to be an Interest Election Request or
a  Credit  Request,  as  applicable,  for  an  ABR  Borrowing.  Furthermore,  if  any  Term  Benchmark  Loan  is  outstanding  on  the  date  of  the
Borrower’s receipt of the notice from the Administrative Agent referred to in this Section 3.4(a) with respect to such Term Benchmark Loan,
then until (x) the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist
with respect to the relevant Benchmark and (y) the Borrower delivers a new Interest Election Request in accordance with the terms of Section
3.2 or a new Credit Request in accordance with the terms of Section 2.3, (1) any Term Benchmark Loan shall on the last day of the Interest
Period applicable to such Loan (or the next succeeding Business Day if such day is not a Business Day), be converted by the Administrative
Agent to, and shall constitute, an ABR Loan.

(b)

Notwithstanding anything to the contrary herein or in any other Loan Document, if a Benchmark Transition Event
and  its  related  Benchmark  Replacement  Date  have  occurred  prior  to  the  Reference  Time  in  respect  of  any  setting  of  the  then-current
Benchmark, then (x) if a Benchmark Replacement is determined in accordance with clause (1) of the definition of “Benchmark Replacement”
for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under
any Loan Document in respect of such Benchmark setting and subsequent Benchmark settings without any amendment to, or further action
or  consent  of  any  other  party  to,  this  Agreement  or  any  other  Loan  Document  and  (y)  if  a  Benchmark  Replacement  is  determined  in
accordance  with  clause  (2)  of  the  definition  of  “Benchmark  Replacement”  for  such  Benchmark  Replacement  Date,  such  Benchmark
Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of any Benchmark setting at
or after 5:00 p.m. on the fifth Business Day after the date notice of such Benchmark Replacement is provided to the Lenders without any
amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document so long as the Administrative
Agent has not received, by such time, written notice of objection to such Benchmark Replacement from Lenders comprising the Required
Lenders.

Notwithstanding anything to the contrary herein or in any other Loan Document, the Administrative Agent will have
the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in
any other Loan Document, any amendments implementing such Benchmark Replacement Conforming

(c)

744315352 11074672    37     ALLETE CREDIT AGREEMENT

Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document.

(d)

The  Administrative  Agent  will  promptly  notify  the  Borrower  and  the  Lenders  of  any  occurrence  of  a  Benchmark
Transition  Event,  the  implementation  of  any  Benchmark  Replacement,  the  effectiveness  of  any  Benchmark  Replacement  Conforming
Changes, the removal or reinstatement of any tenor of a Benchmark pursuant to clause (e) below and the commencement or conclusion of
any  Benchmark  Unavailability  Period.  Any  determination,  decision  or  election  that  may  be  made  by  the  Administrative  Agent  or,  if
applicable,  any  Lender  (or  group  of  Lenders)  pursuant  to  this  Section  3.4,  including  any  determination  with  respect  to  a  tenor,  rate  or
adjustment  or  of  the  occurrence  or  non-occurrence  of  an  event,  circumstance  or  date  and  any  decision  to  take  or  refrain  from  taking  any
action  or  any  selection,  will  be  conclusive  and  binding  absent  manifest  error  and  may  be  made  in  its  or  their  sole  discretion  and  without
consent from any other party to this Agreement or any other Loan Document, except, in each case, as expressly required pursuant to this
Section 3.4.

(e)

Notwithstanding  anything  to  the  contrary  herein  or  in  any  other  Loan  Document,  at  any  time  (including  in
connection  with  the  implementation  of  a  Benchmark  Replacement),  (i)  if  the  then-current  Benchmark  is  a  term  rate  (including  the  Term
SOFR Rate) and either any tenor for such Benchmark is not displayed on a screen or other information service that publishes such rate from
time to time as selected by the Administrative Agent in its reasonable discretion or the regulatory supervisor for the administrator of such
Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is or will be no
longer representative, then the Administrative Agent may modify the definition of “Interest Period” for any Benchmark settings at or after
such time to remove such unavailable or non-representative tenor and (ii) if a tenor that was removed pursuant to clause (i) above either is
subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or is not, or is no longer,
subject to an announcement that it is or will no longer be representative for a Benchmark (including a Benchmark Replacement), then the
Administrative  Agent  may  modify  the  definition  of  “Interest  Period”  for  all  Benchmark  settings  at  or  after  such  time  to  reinstate  such
previously removed tenor.

(f)

Upon the Borrower’s receipt of notice of the commencement of a Benchmark Unavailability Period, the Borrower
may  revoke  any  request  for  a  Term  Benchmark  Borrowing  of,  conversion  to  or  continuation  of  Term  Benchmark  Loans  to  be  made,
converted or continued during any Benchmark Unavailability Period and, failing that, the Borrower will be deemed to have converted any
request for a Term Benchmark Borrowing into a request for a Borrowing of or conversion to an ABR Borrowing. During  any  Benchmark
Unavailability Period or at any time that a tenor for the then-current Benchmark is not an Available Tenor, the component of ABR based
upon  the  then-current  Benchmark  or  such  tenor  for  such  Benchmark,  as  applicable,  will  not  be  used  in  any  determination  of  ABR.
Furthermore,  if  any  Term  Benchmark  Loan  is  outstanding  on  the  date  of  the  Borrower’s  receipt  of  notice  of  the  commencement  of  a
Benchmark Unavailability Period, then until such time as a Benchmark Replacement is implemented pursuant to this Section 3.4, (1) any
Term Benchmark Loan shall on the last day of the Interest Period applicable to such Loan (or the next succeeding Business Day if such day is
not a Business Day), be converted by the Administrative Agent to, and shall constitute, an ABR Loan.

Section 1.5.

Increased Costs; Illegality.

(a)

If any Change in Law shall:

(i)

impose,  modify  or  deem  applicable  any  reserve,  special  deposit,  liquidity  or  similar  requirement  against
assets of, deposits with or for the account of, or credit extended by, any Credit Party (except any such reserve requirement
reflected in the Adjusted Term SOFR Rate);

(ii)

subject any Recipient to any Taxes with respect to this Agreement or on its Loans, loan principal, Letters of

Credit, Commitments, or other obligations, or

744315352 11074672    38     ALLETE CREDIT AGREEMENT

its deposits, reserves, other liabilities or capital attributable thereto in respect thereof (other than (A) Indemnified Taxes and
(B) Excluded Taxes); or

(iii)

impose  on  any  Credit  Party  or  the  applicable  offshore  interbank  market  any  other  condition  affecting  this
Agreement, any Term Benchmark Loans made by such Credit Party or any participation therein or any Letter of Credit or
participation therein;

and the result of any of the foregoing shall be to increase the cost to such Credit Party of making, continuing, converting or maintaining any
Term  Benchmark  Loan  or  the  cost  to  such  Credit  Party  of  issuing,  participating  in  or  maintaining  any  Letter  of  Credit  hereunder  or  to
increase the cost to such Credit Party or to reduce the amount of any sum received or receivable by such Credit Party hereunder (whether of
principal, interest or otherwise), then the Borrower will pay to such Credit Party such additional amount or amounts as will compensate such
Credit Party for such additional costs incurred or reduction suffered.

(b)

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

(c)

A certificate of a Credit Party setting forth the amount or amounts necessary to compensate such Credit Party or its
holding company, as applicable, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive
and binding upon all parties hereto absent manifest error. The Borrower shall pay such Credit Party the amount shown as due on any such
certificate within 10 Business Days after receipt thereof.

(d)

Failure or delay on the part of any Credit Party to demand compensation pursuant to this Section shall not constitute
a waiver of such Credit Party’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Credit
Party  pursuant  to  this  Section  for  any  increased  costs  or  reductions  incurred  more  than  180  days  prior  to  the  date  that  such  Credit  Party
notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Credit Party’s intention to claim
compensation therefor; and provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then
the 180 day period referred to above shall be extended to include the period of retroactive effect thereof but not to exceed a period of 365
days.

Notwithstanding any other provision of this Agreement, if any Change in Law shall make it unlawful for any Lender
to  make  or  maintain  any  Term  Benchmark  Loan  or  to  give  effect  to  its  obligations  as  contemplated  hereby  with  respect  to  any  Term
Benchmark Loan, then, by written notice to the Borrower and to the Administrative Agent:

(e)

(i)

such  Lender  may  declare  that  Term  Benchmark  Loans  will  not  thereafter  (for  the  duration  of  such
unlawfulness) be made by such Lender hereunder (or be continued for additional Interest Periods) and ABR Loans will not
thereafter  (for  such  duration)  be  converted  into  Term  Benchmark  Loans,  whereupon  any  request  for  a  Term  Benchmark
Borrowing or to convert an ABR Borrowing to a Term Benchmark Borrowing or to continue a Term Benchmark Borrowing,
as applicable, for an additional Interest Period shall, as to such Lender only, be deemed a request for an ABR Loan (or a
request to continue an ABR Loan as such for an additional Interest

744315352 11074672    39     ALLETE CREDIT AGREEMENT

Period  or  to  convert  a  Term  Benchmark  Loan  into  an  ABR  Loan,  as  applicable),  unless  such  declaration  shall  be
subsequently withdrawn; and

(ii)

such  Lender  may  require  that  all  outstanding  Term  Benchmark  Loans  made  by  it  be  converted  to  ABR
Loans, in which event all such Term Benchmark Loans shall be automatically converted to ABR Loans, as of the effective
date of such notice as provided in the last sentence of this paragraph.

In  the  event  any  Lender  shall  exercise  its  rights  under  clause (i)  or  (ii)  of  this  paragraph,  all  payments  and  prepayments  of  principal  that
would otherwise have been applied to repay the Term Benchmark Loans that would have been made by such Lender or the converted Term
Benchmark Loans of such Lender shall instead be applied to repay the ABR Loans made by such Lender in lieu of, or resulting from the
conversion of, such Term Benchmark Loans, as applicable. For purposes of this paragraph, a notice to the Borrower by any Lender shall be
effective as to each Term Benchmark Loan made by such Lender, if lawful, on the last day of the Interest Period currently applicable to such
Term Benchmark Loan; in all other cases such notice shall be effective on the date of receipt by the Borrower.

Section 1.6.

Break Funding Payments. In  the  event  of  the  payment  or  prepayment  (voluntary  or  otherwise)  of  any  principal  of
any Term Benchmark Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default),
the  conversion  of  any  Term  Benchmark  Loan  other  than  on  the  last  day  of  the  Interest  Period  applicable  thereto,  the  failure  to  borrow,

(a)

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

Authority pursuant to this Section, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued
by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment
reasonably satisfactory to the Administrative Agent.

(d)

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

(e)

Indemnification  by  the  Lenders. Each  Lender  shall  severally  indemnify  the  Administrative  Agent,  within  10  days
after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already
indemnified  the  Administrative  Agent  for  such  Indemnified  Taxes  and  without  limiting  the  obligation  of  the  Borrower  to  do  so),  (ii)  any
Taxes  attributable  to  such  Lender’s  failure  to  comply  with  the  provisions  of  Section  10.4(d)  relating  to  the  maintenance  of  a  Participant
Register  and  (iii)  any  Excluded  Taxes  attributable  to  such  Lender,  in  each  case,  that  are  payable  or  paid  by  the  Administrative  Agent  in
connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were
correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability
delivered  to  any  Lender  by  the  Administrative  Agent  shall  be  conclusive  absent  manifest  error.  Each  Lender  hereby  authorizes  the
Administrative  Agent  to  setoff  and  apply  any  and  all  amounts  at  any  time  owing  to  such  Lender  under  any  Loan  Document  or  otherwise
payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this
paragraph (e).

(f)

Status of Lenders.

(i)

Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments
made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably
requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably
requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a
reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent,
shall  deliver  such  other  documentation  prescribed  by  applicable  law  or  reasonably  requested  by  the  Borrower  or  the
Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is
subject  to  backup  withholding  or  information  reporting  requirements.  Notwithstanding  anything  to  the  contrary  in  the
preceding two sentences, the completion, execution and submission of such documentation (other than such documentation
set forth in Section 3.7(f)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such
completion,  execution  or  submission  would  subject  such  Lender  to  any  material  unreimbursed  cost  or  expense  or  would
materially prejudice the legal or commercial position of such Lender.

(ii)

Without limiting the generality of the foregoing, in the event that the Borrower is a U.S. Person,

(A)

any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to

reasonable request of the Borrower or the Administrative Agent), an executed copy of IRS Form W-9 certifying that such
Lender is exempt from U.S. federal backup withholding tax;

(B)

any  Foreign  Lender  shall,  to  the  extent  it  is  legally  entitled  to  do  so,  deliver  to  the  Borrower  and  the

pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any
Loan Document, IRS Form W-8BEN-E or IRS Form W-8BEN establishing an exemption from, or reduction of, U.S.
federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

2.

in the case of a Foreign Lender claiming that its extension of credit will generate U.S. effectively

connected income, an executed copy of IRS Form W-8ECI;

Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the
Borrower within the meaning of Section 881(h)(3)(B) of the Code, or a “controlled foreign corporation” described in
Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) an executed copy of IRS Form W-
8BEN-E or IRS Form W-8BEN; or

4.

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

(C)

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

(D)

imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including
those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the
Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower
or the Administrative Agent such documentation prescribed by applicable law (including as

744315352 11074672    42     ALLETE CREDIT AGREEMENT

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

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

(g)

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

Survival.  Each  party’s  obligations  under  this  Section  shall  survive  the  resignation  or  replacement  of  the
Administrative  Agent  or  any  assignment  of  rights  by,  or  the  replacement  of,  a  Lender,  the  termination  of  the  Commitments  and  the
repayment, satisfaction or discharge of all obligations under any Loan Document.

Section 1.8. Mitigation Obligations.

(a)

Designation  of  a  Different  Lending  Office.  In  the  event  that  the  Borrower  becomes  obligated  to  pay  additional
amounts to any Lender (or to any Governmental Authority for the account of any Lender) pursuant to Section 3.5, Section 3.6 or Section 3.7,
then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign
its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or
assignment  (i)  would  eliminate  or  reduce  amounts  payable  pursuant  to  Section 3.5, Section 3.6  or  Section 3.7,  as  the  case  may  be,  in  the
future,  and  (ii)  would  not  subject  such  Lender  to  any  unreimbursed  cost  or  expense  and  would  not  otherwise  be  disadvantageous  to  such
Lender.  The  Borrower  hereby  agrees  to  pay  all  reasonable  costs  and  expenses  incurred  by  any  Lender  in  connection  with  any  such
designation or assignment.

Replacement of Lenders. In the event that the Borrower becomes obligated to pay additional amounts to any Lender
(or to any Governmental Authority for the account of any Lender) pursuant to Section 3.5, Section 3.6 or Section 3.7, any Lender becomes a
Defaulting Lender,

(b)

744315352 11074672    43     ALLETE CREDIT AGREEMENT

or if any Lender has failed to consent to a proposed amendment, waiver, discharge or termination that under Section 10.2 requires the consent
of all the Lenders and with respect to which the Required Lenders shall have granted their consent, then the Borrower may, at its sole cost
and expense, within 60 days of the demand by such Lender for such additional amounts or the relevant default or action or inaction by such
Lender, as the case may be, and subject to and in accordance with the provisions of Section 10.4 (with the Borrower obligated to pay any
applicable processing and recordation fee), designate an Eligible Assignee (acceptable to the Administrative Agent and the Issuing Banks) to
purchase and assume all of such Lender’s interests, rights and obligations under the Loan Documents, without recourse to or warranty by or
expense to, such Lender, for a purchase price equal to the outstanding principal amount of such Lender’s Loans plus any accrued but unpaid
interest thereon and accrued but unpaid facility fees and letter of credit fees in respect of such Lender’s Commitment and any other amounts
payable to such Lender hereunder, and to assume all the obligations of such Lender hereunder, and, upon such purchase, such Lender shall no
longer  be  a  party  hereto  or  have  any  rights  hereunder  (except  those  that  survive  full  repayment  hereunder)  and  shall  be  relieved  from  all
obligations to the Borrower hereunder, and the Eligible Assignee shall succeed to the rights and obligations of such Lender hereunder. No
replacement  of  a  Defaulting  Lender  pursuant  to  this  Section  3.8  shall  be  deemed  to  be  a  waiver  of  any  right  that  the  Borrower,  the
Administrative Agent, the Issuing Banks or any other Lender may have against such Defaulting Lender. Upon request, the Borrower shall
execute and deliver to such Eligible Assignee a Note. Notwithstanding anything herein to the contrary, in the event that a Lender is replaced
pursuant  to  this  Section  3.8  as  a  result  of  the  Borrower  becoming  obligated  to  pay  additional  amounts  to  such  Lender  (or  to  any
Governmental Authority for the account of any Lender) pursuant to Section 3.5, Section 3.6 or Section 3.7, such Lender shall be entitled to
receive such additional amounts as if it had not been so replaced, except as otherwise provided in Section 2.11  if  such  Lender  becomes  a
Defaulting Lender.

Section 1.10.

Plan Assets; Prohibited Transactions. None of the Borrower or any of its Subsidiaries is an entity deemed to hold
“plan  assets”  (within  the  meaning  of  the  Plan  Asset  Regulations),  and  neither  the  execution,  delivery  nor  performance  of  the  transactions
contemplated under this Agreement, including the making of any Loan and the issuance of any Letter of Credit hereunder, will give rise to a
non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code.

Article 4.

REPRESENTATIONS AND WARRANTIES

The Borrower represents and warrants to the Credit Parties that:

Section 1.1.

Organization; Powers. Each of the Borrower and each Subsidiary is duly organized or formed, validly existing and in
good standing under the laws of the jurisdiction of its organization or formation, has all requisite corporate power and authority to carry on its
business as now conducted and, except where the failure to do so, individually or in the aggregate, would not reasonably be expected to result
in a Material Adverse Effect, is qualified to do business in, and is in good standing in, every jurisdiction where such qualification is required.

bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally and general principles of equity.

(a)

The execution, delivery and performance by the Borrower of the Loan Documents and the borrowing of the Loans
and the issuance of the Letters of Credit do not require any consent or approval of, registration or filing with, or any other action by, any

the Borrower’s performance under the Loan Documents and (ii) such as have been obtained or made and are in full force and effect and not
subject to any appeals period.

(b)

The  Transactions  will  not  (i)  violate  the  charter,  by-laws  or  other  organizational  documents  of  the  Borrower,  (ii)
violate any applicable law or regulation or any order of any Governmental Authority, (iii) violate or result in a default under any material
indenture, agreement or other instrument binding upon the Borrower or its assets, or give rise to a right thereunder to require any payment to
be made by the Borrower, and (iv) result in or require the creation or imposition of any Lien on any asset of the Borrower.

Section 1.4.

Financial Condition; No Material Adverse Change.

(a)

The  Borrower  has  previously  delivered  to  the  Credit  Parties  copies  of  its  Form  10-K  for  the  fiscal  year  ended

consolidated  statements  of  operations,  comprehensive  income,  changes  in  stockholders’  equity  and  cash  flows  for  the  fiscal  year  ending
December  31,  2017  (including  with  the  applicable  related  notes  and  schedules,  the  “Borrower  Financial  Statements”),  and  the  unaudited
consolidated balance sheet of the Borrower and its Subsidiaries and the related unaudited consolidated statements of income, equity and cash

against or, to the knowledge of the Borrower, threatened in writing against or affecting the Borrower or any Subsidiary that (a) if adversely
determined  (and  provided  that  there  exists  a  reasonable  possibility  of  such  adverse  determination),  would  reasonably  be  expected,
individually or in the aggregate, to result in a Material Adverse Effect, except for any Disclosed Matters, and except that the commencement
by the Borrower, any Subsidiary or any Governmental Authority of a rate proceeding, fuel adjustment clause audit or earnings review before
such Governmental Authority shall not constitute such a pending or threatened action, suit or proceeding unless and until such Governmental
Authority has made a final determination thereunder that would reasonably be expected to have a Material Adverse Effect, or (b) involve any
Loan Document or the Transactions.

Section 1.6.

Environmental Matters. Except for the Disclosed Matters, the Borrower and its Subsidiaries (a) are in compliance
with Environmental Law, (b) have received all permits, licenses or other approvals required of them under applicable Environmental Law to

“controlled” by an “investment company” as defined in, or is otherwise subject to regulation under, the Investment Company Act of 1940.

Section 1.8.

ERISA. Each  of  the  Borrower  and  each  of  its  ERISA  Affiliates  is  in  compliance  in  all  material  respects  with  the

Adverse Effect.

report on Form 10-K and in the Borrower’s reports filed with the SEC under the Securities Exchange Act of 1934 subsequent to the filing of
the Form 10-K) contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the
light of the circumstances under which they were made, not materially misleading, provided that, to the extent any such reports, financial

financial  performance,  ongoing  business  strategies  or  prospects  or  possible  future  actions,  and  other  forward-looking  statements),  the

Lender  that  requests  the  Borrower  to  deliver  such  paper  copies  until  a  written  request  to  cease  delivering  paper  copies  is  given  by  the

744315352 11074672    50     ALLETE CREDIT AGREEMENT

and  the  Borrower  shall  notify  the  Administrative  Agent  and  each  Lender  (by  facsimile  or  electronic  mail)  of  the  posting  of  any  such
documents and provide to the Administrative Agent by electronic mail electronic versions (i.e., soft copies) of such documents. Except  for

Legal  Existence.  Except  as  permitted  under  Section  7.2,  the  Borrower  shall  maintain  its  legal  existence  in  good
standing in the jurisdiction of its organization or formation and in each other jurisdiction in which the failure so to do would reasonably be
expected to have a Material Adverse Effect, and cause each of the Subsidiaries to maintain its qualification to do business and good standing
in each jurisdiction in which the failure so to do would reasonably be expected to have a Material Adverse Effect (it being understood that the
foregoing  shall  not  prohibit  the  Borrower  from  dissolving  or  terminating  the  existence  of  any  Subsidiary  that  is  inactive  or  whose
preservation otherwise is no longer desirable in the conduct of the business of the Borrower and its Subsidiaries considered as a whole).

Section  1.4.

Taxes.  The  Borrower  shall  pay  and  discharge  when  due,  and  cause  each  of  the  Subsidiaries  so  to  do,  all  Taxes
imposed upon it or upon its property, which if unpaid would, individually or collectively, reasonably be expected to have a Material Adverse
Effect or become a Lien on the property of the Borrower or such Subsidiary (other than a Lien described in clause (a) of the definition of
Permitted  Encumbrances),  as  the  case  may  be,  unless  and  to  the  extent  only  that  such  Taxes  shall  be  contested  in  good  faith  and  by
appropriate proceedings diligently conducted by the Borrower or such Subsidiary, as the case may be.

Section 1.5.

Insurance. The Borrower shall maintain, and cause each of its Subsidiaries to maintain, with financially sound and
reputable  insurance  companies  insurance  on  all  its  property  in  at  least  such  amounts  and  against  at  least  such  risks  as  are  usually  insured
against in the same general area by companies engaged in the same or a similar business, provided that the Borrower and its Subsidiaries may
self-insure to the same extent as other companies engaged in similar businesses and owning similar properties in the same general areas in
which the Borrower or such Subsidiary operates and to the extent consistent with prudent business practice. The Borrower shall furnish to the
Administrative Agent, upon written request of the Administrative Agent or any Lender, full information as to the insurance carried.

Condition of Property. The Borrower shall at all times maintain, protect and keep in good repair, working order and
condition  in  all  material  respects  (ordinary  wear  and  tear  excepted),  and  cause  each  of  its  Subsidiaries  so  to  do,  all  material  property
necessary  to  the  operation  of  the  Borrower’s  or  such  Subsidiary’s,  as  the  case  may  be,  material  businesses,  provided  that  nothing  shall
prevent  the  Borrower  or  its  Subsidiaries,  as  appropriate,  from  discontinuing  the  maintenance  or  operation  of  any  property  if  such
discontinuance  is,  in  the  judgment  of  the  Borrower  or  such  Subsidiary,  desirable  in  the  conduct  of  the  business  of  the  Borrower  or  such
Subsidiary.  It  is  understood  that  this  covenant  relates  only  to  working  order  and  condition  of  such  property  in  accordance  with  prudent
industry practices and shall not be construed as a covenant not to dispose of property.

Section 1.7.

Observance of Legal Requirements. The Borrower shall observe and comply in all material respects, and cause each
of its Subsidiaries so to do, with all laws, regulations and orders of any Governmental Authority which now or at any time hereafter may be
applicable  to  it,  including  ERISA  and  all  Environmental  Laws,  a  violation  of  which  would  individually  or  collectively  reasonably  be
expected  to  have  a  Material  Adverse  Effect,  except  such  thereof  as  shall  be  contested  in  good  faith  and,  if  applicable,  by  appropriate
proceedings diligently conducted by it.

Section  1.8.

Inspection  of  Property;  Books  and  Records;  Discussions.  The  Borrower  shall  keep  proper  books  of  record  and
account in conformity with GAAP and all requirements of law. The Borrower shall permit representatives of the Administrative Agent and
any Lender to visit its offices,

744315352 11074672    51     ALLETE CREDIT AGREEMENT

to inspect any of its property (subject to reasonable procedures relating to safety and security) and examine and make copies or abstracts from
any  of  its  books  and  records  at  any  reasonable  time  and  as  often  as  may  reasonably  be  desired,  and  to  discuss  the  business,  operations,
prospects, property and financial condition of the Borrower and its Subsidiaries with the officers thereof and the Accountants; provided that
none of the Administrative Agent, its agents, its representatives or the Lenders shall be entitled to examine or make copies or abstracts of, or
otherwise obtain information with respect to, the Borrower’s records relating to pending or threatened litigation if any such disclosure by the
Borrower would reasonably be expected (i) to give rise to a waiver of any attorney/client privilege of the Borrower or any of its Subsidiaries
relating to such information or (ii) to be otherwise materially disadvantageous to the Borrower or any of its Subsidiaries in the defense of
such  litigation;  and  provided  further  that  in  the  case  of  any  discussion  with  the  Accountants,  the  Borrower  shall  have  been  given  the
opportunity to participate in such discussion and, unless a Default exists, the Lender or Lenders requesting such discussion shall pay any fees
and expenses of the Accountant in connection therewith.

Article 9.

THE ADMINISTRATIVE AGENT

Section 1.1.

Authorization and Action.

Each  Credit  Party  hereby  irrevocably  appoints  the  Administrative  Agent  as  its  agent  and  authorizes  the
Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms
hereof, together with such actions and powers as are reasonably incidental thereto.

(a)

(b)

The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a
Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and such Person and its Affiliates
may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate
thereof as if it were not the Administrative Agent hereunder.

(c)

As  to  any  matters  not  expressly  provided  for  herein  and  in  the  other  Loan  Documents  (including  enforcement  or
collection), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to
refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the written instructions of the Required Lenders
(or such other number or percentage of the Lenders as shall be necessary, pursuant to the terms in the Loan Documents), and, unless and until
revoked in writing, such instructions shall be binding upon each Lender and each Issuing Bank; provided, however, that the Administrative
Agent  shall  not  be  required  to  take  any  action  that  (i)  the  Administrative  Agent  in  good  faith  believes  exposes  it  to  liability  unless  the
Administrative Agent receives an indemnification and is exculpated in a manner satisfactory to it from the Lenders and the Issuing Banks
with respect to such action or (ii) is contrary to this Agreement or any other Loan Document or applicable law, including any action that may
be in violation of the automatic stay under any requirement of law relating to bankruptcy, insolvency or reorganization or relief of debtors or
that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any requirement of law relating to
bankruptcy,  insolvency  or  reorganization  or  relief  of  debtors;  provided,  further,  that  the  Administrative  Agent  may  seek  clarification  or
direction from the Required Lenders prior to the exercise of any such instructed action and may refrain from acting until such clarification or
direction  has  been  provided.  Except  as  expressly  set  forth  in  the  Loan  Documents,  the  Administrative  Agent  shall  not  have  any  duty  to
disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower, any Subsidiary or any Affiliate of any of
the  foregoing  that  is  communicated  to  or  obtained  by  the  Person  serving  as  Administrative  Agent  or  any  of  its  Affiliates  in  any  capacity.
Nothing in this Agreement shall require the Administrative Agent to expend or risk its own funds or otherwise incur any financial liability in
the performance of any of its duties hereunder or in the exercise of any of its

744315352 11074672    57     ALLETE CREDIT AGREEMENT

rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or
liability is not reasonably assured to it.

(d)

In performing its functions and duties hereunder and under the other Loan Documents, the Administrative Agent is
acting solely on behalf of the Lenders and the Issuing Banks (except in limited circumstances expressly provided for herein relating to the
maintenance  of  the  Register),  and  its  duties  are  entirely  mechanical  and  administrative  in  nature.  Without  limiting  the  generality  of  the
foregoing:

(i)

the Administrative Agent does not assume and shall not be deemed to have assumed any obligation or duty
or any other relationship as the agent, fiduciary or trustee of or for any Lender or Issuing Bank other than as expressly set
forth herein and in the other Loan Documents, regardless of whether a Default or an Event of Default has occurred and is
continuing (and it is understood and agreed that the use of the term “agent” (or any similar term) herein or in any other Loan
Document  with  reference  to  the  Administrative  Agent  is  not  intended  to  connote  any  fiduciary  duty  or  other  implied  (or
express) obligations arising under agency doctrine of any applicable law, and that such term is used as a matter of market
custom and is intended to create or reflect only an administrative relationship between contracting parties); additionally, each
Lender agrees that it will not assert any claim against the Administrative Agent based on an alleged breach of fiduciary duty
by the Administrative Agent in connection with this Agreement and/or the transactions contemplated hereby; and

(ii)

nothing in this Agreement or any Loan Document shall require the Administrative Agent to account to any

Lender for any sum or the profit element of any sum received by the Administrative Agent for its own account;

(e)

The Administrative Agent may perform any of its duties and exercise its rights and powers hereunder or under any
other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any
such sub-agent may perform any of their respective duties and exercise their respective rights and powers through their respective Related
Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Administrative Agent
and  any  such  sub-agent,  and  shall  apply  to  their  respective  activities  pursuant  to  this  Agreement.  The  Administrative  Agent  shall  not  be
responsible for the negligence or misconduct of any sub-agent except to the extent that a court of competent jurisdiction determines in a final
and nonappealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub-
agent.

The Sole Lead Arranger and Sole Bookrunner shall have no obligations or duties whatsoever in such capacity under
this Agreement or any other Loan Document and shall incur no liability hereunder or thereunder in such capacity, but shall have the benefit
of the indemnities provided for hereunder.

(f)

(g)

In  case  of  the  pendency  of  any  proceeding  with  respect  to  the  Borrower  under  any  Federal,  state  or  foreign
bankruptcy, insolvency, receivership or similar law now or hereafter in effect, the Administrative Agent (irrespective of whether the principal
of any Loan or any reimbursement obligation in respect of any LC Disbursement shall then be due and payable as herein expressed or by
declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled
and empowered (but not obligated) by intervention in such proceeding or otherwise:

(i)

to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of
the Loans, LC Disbursements and all other obligations under the Loan Documents that are owing and unpaid and to file such
other documents as may be necessary or advisable in order to have the claims of the

744315352 11074672    58     ALLETE CREDIT AGREEMENT

Lenders, the Issuing Banks and the Administrative Agent (including any claim under Sections 3.1, 3.3, 3.5,  3.7  and  10.3)
allowed in such judicial proceeding; and

(ii)
distribute the same;

to  collect  and  receive  any  monies  or  other  property  payable  or  deliverable  on  any  such  claims  and  to

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such proceeding is hereby authorized by
each Lender and each Issuing Bank to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall
consent to the making of such payments directly to the Lenders and the Issuing Banks, to pay to the Administrative Agent any amount due to
it, in its capacity as the Administrative Agent, under the Loan Documents (including under Section 10.3). Nothing contained herein shall be
deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender or Issuing Bank any plan
of  reorganization,  arrangement,  adjustment  or  composition  affecting  the  obligations  or  the  rights  of  any  Lender  or  Issuing  Bank  or  to
authorize the Administrative Agent to vote in respect of the claim of any Lender or Issuing Bank in any such proceeding.

(h)

The  provisions  of  this  Article  are  solely  for  the  benefit  of  the  Administrative  Agent,  the  Lenders  and  the  Issuing
Banks, and, except solely to the extent of the Borrower’s rights to consent pursuant to and subject to the conditions set forth in this Article,
none of the Borrower or any Subsidiary, or any of their respective Affiliates, shall have any rights as a third party beneficiary under any such
provisions.

Section 1.2.

Administrative Agent’s Reliance, Indemnification, Etc.

(a)

Neither the Administrative Agent nor any of its Related Parties shall be (i) liable for any action taken or omitted to
be taken by such party under or in connection with this Agreement or the other Loan Documents (x) with the consent of or at the request of
the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe
in good faith to be necessary, under the circumstances as provided in the Loan Documents) or (y) in the absence of its own gross negligence
or willful misconduct (such absence to be presumed unless otherwise determined by a court of competent jurisdiction by a final and non-
appealable judgment) or (ii) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made
the Borrower or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other
document referred to or provided for in, or received by the Administrative Agent under or in connection with, this Agreement or any other
Loan  Document  or  for  the  value,  validity,  effectiveness,  genuineness,  enforceability  or  sufficiency  of  this  Agreement  or  any  other  Loan
Document or for any failure of the Borrower to perform its obligations hereunder or thereunder.

(b)

The  Administrative  Agent  shall  be  deemed  not  to  have  knowledge  of  any  Default  unless  and  until  written  notice
thereof (stating that it is a “notice of default”) is given to the Administrative Agent by the Borrower, a Lender or an Issuing Bank, and the
Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation
made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered thereunder or in
connection therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any
Loan  Document  or  the  occurrence  of  any  Default,  (iv)  the  sufficiency,  validity,  enforceability,  effectiveness  or  genuineness  of  any  Loan
Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article 5 or elsewhere in any
Loan Document, other than to confirm receipt of items (which on their face purport to be such items) expressly required to be delivered to the
Administrative Agent or satisfaction of any condition that expressly refers to the matters described therein being acceptable or satisfactory to
the Administrative Agent.

Without limiting the foregoing, the Administrative Agent (i) may treat the payee of any Note as its holder until such
Note has been assigned in accordance with Section 10.4,  (ii)  may  rely  on  the  Register  to  the  extent  set  forth  in  Section 10.4(c),  (iii)  may
consult with legal counsel

(c)

744315352 11074672    59     ALLETE CREDIT AGREEMENT

(including counsel to the Borrower), independent public accountants and other experts selected by it, and shall not be liable for any action
taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts, (iv) makes no warranty
or representation to any Lender or Issuing Bank and shall not be responsible to any Lender or Issuing Bank for any statements, warranties or
representations made by or on behalf of the Borrower in connection with this Agreement or any other Loan Document, (v) in determining
compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to
the satisfaction of a Lender or an Issuing Bank, may presume that such condition is satisfactory to such Lender or Issuing Bank unless the
Administrative Agent shall have received notice to the contrary from such Lender or Issuing Bank sufficiently in advance of the making of
such Loan or the issuance of such Letter of Credit and (vi) shall be entitled to rely on, and shall incur no liability under or in respect of this
Agreement or any other Loan Document by acting upon, any notice, consent, certificate or other instrument or writing (which writing may be
a fax, any electronic message, Internet or intranet website posting or other distribution) or any statement made to it orally or by telephone and
believed by it to be genuine and signed or sent or otherwise authenticated by the proper party or parties (whether or not such Person in fact
meets the requirements set forth in the Loan Documents for being the maker thereof).

Section 1.3.

Posting of Communications; Limitation of Liability.

The Borrower agrees that the Administrative Agent may, but shall not be obligated to, make any Communications
available to the Lenders and the Issuing Banks by posting the Communications on IntraLinks™, DebtDomain, SyndTrak, ClearPar or any
other electronic platform chosen by the Administrative Agent to be its electronic transmission system (the “Approved Electronic Platform”).

(a)

(b)

Although  the  Approved  Electronic  Platform  and  its  primary  web  portal  are  secured  with  generally-applicable
security procedures and policies implemented or modified by the Administrative Agent from time to time (including, as of the Effective Date,
a user ID/password authorization system) and the Approved Electronic Platform is secured through a per-deal authorization method whereby
each user may access the Approved Electronic Platform only on a deal-by-deal basis, each of the Lenders, each of the Issuing Banks and the
Borrower  acknowledges  and  agrees  that  the  distribution  of  material  through  an  electronic  medium  is  not  necessarily  secure,  that  the
Administrative Agent is not responsible for approving or vetting the representatives or contacts of any Lender that are added to the Approved
Electronic Platform, and that there may be confidentiality and other risks associated with such distribution. Each of the Lenders, each of the
Issuing  Banks  and  the  Borrower  hereby  approves  distribution  of  the  Communications  through  the  Approved  Electronic  Platform  and
understands and assumes the risks of such distribution.

(c)

THE  APPROVED  ELECTRONIC  PLATFORM  AND  THE  COMMUNICATIONS  ARE  PROVIDED  “AS  IS”
AND  “AS  AVAILABLE”.  THE  APPLICABLE  PARTIES  DO  NOT  WARRANT  THE  ACCURACY  OR  COMPLETENESS  OF  THE
COMMUNICATIONS,  OR  THE  ADEQUACY  OF  THE  APPROVED  ELECTRONIC  PLATFORM  AND  EXPRESSLY  DISCLAIM
LIABILITY FOR ERRORS OR OMISSIONS IN THE APPROVED ELECTRONIC PLATFORM AND THE COMMUNICATIONS. NO
WARRANTY  OF  ANY  KIND,  EXPRESS,  IMPLIED  OR  STATUTORY,  INCLUDING  ANY  WARRANTY  OF  MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR
OTHER CODE DEFECTS, IS MADE BY THE APPLICABLE PARTIES IN CONNECTION WITH THE COMMUNICATIONS OR THE
APPROVED ELECTRONIC PLATFORM.

IN NO EVENT SHALL THE ADMINISTRATIVE AGENT, THE SOLE LEAD ARRANGER AND SOLE BOOKRUNNER OR ANY OF
THEIR RESPECTIVE RELATED PARTIES (COLLECTIVELY, “APPLICABLE PARTIES”) HAVE ANY LIABILITY TO ANY LENDER,
ANY  ISSUING  BANK  OR  ANY  OTHER  PERSON  OR  ENTITY  FOR  DAMAGES  OF  ANY  KIND,  INCLUDING  DIRECT  OR
INDIRECT,  SPECIAL,  INCIDENTAL  OR  CONSEQUENTIAL  DAMAGES,  LOSSES  OR  EXPENSES  (WHETHER  IN  TORT,
CONTRACT OR OTHERWISE)

744315352 11074672    60     ALLETE CREDIT AGREEMENT

ARISING  OUT  OF  THE  BORROWER’S  OR  THE  ADMINISTRATIVE  AGENT’S  TRANSMISSION  OF  COMMUNICATIONS
THROUGH THE INTERNET OR THE APPROVED ELECTRONIC PLATFORM.

NO CREDIT PARTY NOR ANY OF THEIR RESPECTIVE RELATED PARTIES SHALL BE LIABLE TO THE BORROWER FOR ANY
USE BY OTHERS OF INFORMATION OR OTHER MATERIALS (INCLUDING, WITHOUT LIMITATION, ANY PERSONAL DATA)
OBTAINED  THROUGH  TELECOMMUNICATIONS,  ELECTRONIC  OR  OTHER  INFORMATION  TRANSMISSION  SYSTEMS
(INCLUDING  THE  ELECTRONIC  PLATFORM)  EXCEPT  TO  THE  EXTENT  SUCH  LIABILITIES  ARE  FOUND  IN  A  FINAL
JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE ARISEN FROM SUCH PARTY’S GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT.

“Communications”  means,  collectively,  any  notice,  demand,  communication,  information,  document  or  other  material  provided  by  or  on
behalf of the Borrower pursuant to any Loan Document or the transactions contemplated therein which is distributed by the Administrative
Agent,  any  Lender  or  any  Issuing  Bank  by  means  of  electronic  communications  pursuant  to  this  Section,  including  through  an  Approved
Electronic Platform.

(d)

Each  Lender  and  each  Issuing  Bank  agrees  that  notice  to  it  (as  provided  in  the  next  sentence)  specifying  that
Communications have been posted to the Approved Electronic Platform shall constitute effective delivery of the Communications to such
Lender for purposes of the Loan Documents. Each Lender and Issuing Bank agrees (i) to notify the Administrative Agent in writing (which
could be in the form of electronic communication) from time to time of such Lender’s or Issuing Bank’s (as applicable) email address to
which the foregoing notice may be sent by electronic transmission and (ii) that the foregoing notice may be sent to such email address.

Each  of  the  Lenders,  each  of  the  Issuing  Banks  and  the  Borrower  agrees  that  the  Administrative  Agent  may,  but
(except as may be required by applicable law) shall not be obligated to, store the Communications on the Approved Electronic Platform in
accordance with the Administrative Agent’s generally applicable document retention procedures and policies.

(e)

notice or other communication pursuant to any Loan Document in any other manner specified in such Loan Document.

(f)

Nothing herein shall prejudice the right of the Administrative Agent, any Lender or any Issuing Bank to give any

Section 1.4.

The Administrative Agent Individually. With respect to its Commitment, Loans, Letter of Credit Commitments and
Letters of Credit, the Person serving as the Administrative Agent shall have and may exercise the same rights and powers hereunder and is
subject to the same obligations and liabilities as and to the extent set forth herein for any other Lender or Issuing Bank, as the case may be.
The  terms  “Issuing  Banks”,  “Lenders”,  “Required  Lenders”  and  any  similar  terms  shall,  unless  the  context  clearly  otherwise  indicates,
include the Administrative Agent in its individual capacity as a Lender, Issuing Bank or as one of the Required Lenders, as applicable. The
Person serving as the Administrative Agent and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial
advisor or in any other advisory capacity for and generally engage in any kind of banking, trust or other business with, the Borrower, any
Subsidiary or any Affiliate of any of the foregoing as if such Person was not acting as the Administrative Agent and without any duty to
account therefor to the Lenders or the Issuing Banks.

Section 1.5.

Successor Administrative Agent.

(a)

The Administrative Agent may resign at any time by giving 30 days’ prior written notice thereof to the Lenders, the
Issuing  Banks  and  the  Borrower,  whether  or  not  a  successor  Administrative  Agent  has  been  appointed.  Upon  any  such  resignation,  the
Required Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so
appointed by the Required Lenders, 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 Lenders
and  the  Issuing  Banks,  appoint  a  successor  Administrative  Agent,  which  shall  be  a  bank  with  an  office  in  New  York,  New  York  or  an
Affiliate of any such bank. In either case, such appointment shall be subject to the prior written approval of the Borrower (which approval
may not be unreasonably withheld and shall not be required while an Event of Default has occurred and is continuing). Upon the acceptance
of any appointment as Administrative Agent by a successor Administrative Agent, such successor Administrative Agent shall succeed to, and
become vested with, all the rights, powers, privileges and duties of the retiring Administrative Agent. Upon the acceptance of appointment as
Administrative  Agent  by  a  successor  Administrative  Agent,  the  retiring  Administrative  Agent  shall  be  discharged  from  its  duties  and
obligations  under  this  Agreement  and  the  other  Loan  Documents.  Prior  to  any  retiring  Administrative  Agent’s  resignation  hereunder  as
Administrative  Agent,  the  retiring  Administrative  Agent  shall  take  such  action  as  may  be  reasonably  necessary  to  assign  to  the  successor
Administrative Agent its rights as Administrative Agent under the Loan Documents.

(b)

Notwithstanding  paragraph  (a)  of  this  Section,  in  the  event  no  successor  Administrative  Agent  shall  have  been  so
appointed and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its intent to resign,
the retiring Administrative Agent may give notice of the effectiveness of its resignation to the Lenders, the Issuing Banks and the Borrower,
whereupon, on the date of effectiveness of such resignation stated in such notice, (i) the retiring Administrative Agent shall be discharged
from its duties and obligations hereunder and under the other Loan Documents; and (ii) the Required Lenders shall succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Administrative Agent; provided that (A) all payments required to be
made hereunder or under any other Loan Document to the Administrative Agent for the account of any Person other than the Administrative
Agent shall be made directly to such Person and (B) all notices and other communications required or contemplated to be given or made to
the  Administrative  Agent  shall  directly  be  given  or  made  to  each  Lender  and  each  Issuing  Bank.  Following  the  effectiveness  of  the
Administrative  Agent’s  resignation  from  its  capacity  as  such,  the  provisions  of  this  Article  and  Section 10.3,  as  well  as  any  exculpatory,
reimbursement and indemnification provisions set forth in any other Loan Document, shall continue in effect for the benefit of such retiring
Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them
while the retiring Administrative Agent was acting as Administrative Agent.

Section 1.2. Waivers; Amendments.

(a)

No failure or delay by any Credit Party in exercising any right or power under any Loan Document shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce
such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of
the Credit Parties under the Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have.
No waiver of any provision of any Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective
unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific
instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan and/or the issuance,
amendment, extension or renewal of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether any Credit
Party may have had notice or knowledge of such Default at the time.

(b)

Subject  to  Section  3.4(c),  neither  any  Loan  Document  nor  any  provision  thereof  may  be  waived,  amended  or

Borrower  and  the  Administrative  Agent  with  the  consent  of  the  Required  Lenders,  provided  that  no  such  agreement  shall  increase  the
Commitment of any Lender without the written consent of such Lender or increase the Letter of Credit Commitment of any Issuing Bank
without the consent of such Issuing Bank, reduce the principal amount of any Loan or any reimbursement obligation with respect to a LC
Disbursement, or reduce the rate of any interest, or reduce any fees, payable under the Loan Documents, without the written consent of each
Credit  Party  affected  thereby,  postpone  the  date  of  payment  at  stated  maturity  of  any  Loan  or  the  date  of  payment  of  any  reimbursement
obligation  with  respect  to  an  LC  Disbursement,  or  the  date  of  any  interest  or  any  fees  payable  under  the  Loan  Documents,  or  reduce  the
amount  of,  waive  or  excuse  any  such  payment,  or  postpone  the  stated  termination  or  expiration  of  the  Commitments  without  the  written
consent of each Credit Party affected thereby, change  any  provision  hereof  in  a  manner  that  would  alter  the  pro  rata  sharing  of  payments
required by Section 2.10(b) or 2.10(c) or the pro rata reduction of Commitments required by Section 2.5(c), without the written consent of

release of Hazardous Materials on or from any property owned or operated by the Borrower or any of the Subsidiaries, or any liability under
any  Environmental  Law  related  in  any  way  to  the  Borrower  or  any  of  the  Subsidiaries  or  any  actual  or  prospective  claim,  litigation,
investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any
Indemnitee is a party thereto, provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims,
damages,  liabilities  or  related  expenses  are  determined  by  a  court  of  competent  jurisdiction  by  final  and  nonappealable  judgment  to  have
resulted from the gross negligence or willful misconduct of such Indemnitee or a breach in bad faith by such Indemnitee or arising solely
from claims between or among one or more Indemnitees.

(c)

Reimbursement by Lenders. To the extent that the Borrower fails to pay any amount required to be paid by it to the
Administrative Agent or an Issuing Bank under paragraph (a) or (b) of this Section (and without limiting the Borrower’s obligation to do so),

Commitments plus the outstanding principal balance of all Lenders Loans and the LC Exposure of all Lenders (in each case determined as of
the  time  that  the  applicable  unreimbursed  expense  or  indemnity  payment  is  sought  or,  in  the  event  that  no  Lender  shall  have  any  unused
Commitments,  outstanding  Loans  or  LC  Exposure  at  such  time,  as  of  the  last  time  at  which  any  Lender  had  any  unused  Commitments,
outstanding Loans or LC Exposure), provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense,
as applicable, was incurred by or asserted against the Administrative Agent or an Issuing Bank, as applicable, in its capacity as such.

(d)

Waiver of Consequential Damages, etc. To the extent permitted by applicable law, no party hereto shall assert, and
each such party hereby waives, any claims against any other party hereto, on any theory of liability, for special, indirect, consequential or
punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan

such Lender; and

(C)

the consent of the applicable Issuing Banks (such consent not to be unreasonably withheld or delayed) shall

Sections  3.5,  3.6,  3.7  and  10.3  with  respect  to  facts  and  circumstances  occurring  prior  to  the  effective  date  of  such  assignment.  Any
assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for

(ii)

Upon its receipt of (x) a duly completed Assignment and Assumption executed by an assigning Lender and

to an Approved Electronic Platform as to which the Administrative Agent and the parties to the Assignment and Assumption
are  participants,  the  assignee’s  completed  Administrative  Questionnaire  (unless  the  assignee  shall  already  be  a  Lender
hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such
assignment  required  by  paragraph  (b)  of  this  Section,  the  Administrative  Agent  shall  accept  such  Assignment  and

assignee shall have failed to make any payment required to be made by it pursuant to Section 2.4(b), 2.9(d) or (e), or 10.3(c),
the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information

(d)

Participations.  Any  Lender  may  at  any  time,  without  the  consent  of,  but  with  notice  to,  the  Borrower  and  the
Administrative  Agent  (provided  that  any  failure  to  give  such  notice  shall  not  impair  the  effectiveness  of  such  participation  except  as
expressly provided in paragraph (e) of this Section), sell participations to any Person (other than a natural person or the Borrower or any of
the  Borrower’s  Affiliates  or  Subsidiaries)  (each,  a  “Participant”)  in  all  or  a  portion  of  such  Lender’s  rights  and/or  obligations  under  this
Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this
Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such
obligations,  (iii)  such  Lender  shall  remain  the  holder  of  any  Note  for  all  purposes  of  this  Agreement  and  (iv)  the  Borrower,  the
Administrative Agent and each Credit Party shall continue to deal solely and directly with such Lender in connection with such Lender’s
rights and obligations under this Agreement. Notwithstanding the foregoing, in no event may a participation be granted to any entity which is
not  a  commercial  bank,  finance  company,  insurance  company  or  other  financial  institution  or  fund  (whether  a  corporation,  partnership  or
other  entity)  engaged  generally  in  making,  purchasing  or  otherwise  investing  in  commercial  loans  in  the  ordinary  course  of  its  business
without the express prior written consent of the Borrower.

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided
that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment,
modification  or  waiver  with  respect  to  the  following  matters  described  in  clauses (ii)  and  (iii)  of  the  first  proviso  in  Section  10.2(b)  that
directly affects such Participant. Subject to paragraph (e) of this Section, the Borrower agrees that each Participant shall be entitled to the
benefits  of  Sections  3.5,  3.6  and  3.7  to  the  same  extent  as  if  it  were  a  Lender  and  had  acquired  its  interest  by  assignment  pursuant  to
paragraph (b) of this Section but (x) shall not be entitled to recover greater amounts under any such Section than the selling Lender would be
entitled  to  recover  and  (y)  shall  be  subject  to  replacement  by  the  Borrower  under  Section 3.8  to  the  same  extent  as  if  it  were  a  Lender;
provided that such replacement Participant shall be a commercial bank, finance company, insurance company or other financial institution or
fund (whether a corporation, partnership or other entity) engaged generally in making, purchasing or otherwise investing in commercial loans
in the ordinary course of its business. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.8 as
though it were a Lender, provided such Participant agrees to be subject to Section 2.10(c) as though it were a Lender.

Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain
a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s
interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender

744315352 11074672    70     ALLETE CREDIT AGREEMENT

shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information
relating to a Participant’s interest in any Loans or its other obligations under any Loan Document) to any Person except to the extent that such
disclosure is necessary to establish that such Loan or other obligation is in registered form under Section 5f.103-1(c) of the United States
Treasury  Regulations.  The  entries  in  the  Participant  Register  shall  be  conclusive  absent  manifest  error,  and  such  Lender  shall  treat  each
Person  whose  name  is  recorded  in  the  Participant  Register  as  the  owner  of  such  participation  for  all  purposes  of  this  Agreement
notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent)
shall have no responsibility for maintaining a Participant Register.

(e)

Limitations  upon  Participant  Rights.  A  Participant  shall  not  be  entitled  to  receive  any  greater  payment  under
Sections 3.5 or 3.7 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant,
unless  the  sale  of  the  participation  to  such  Participant  is  made  with  the  Borrower’s  prior  written  consent.  A  Participant  that  would  be  a
Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 3.7 unless the Borrower is notified of the participation sold
to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 3.7(f) as though it were a Lender.

(f)

Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights
under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve
Bank; provided  that  no  such  pledge  or  assignment  shall  release  such  Lender  from  any  of  its  obligations  hereunder  or  substitute  any  such
pledgee or assignee for such Lender as a party hereto.

the provisions of Section 2.11 shall apply for so long as such Lender is a Defaulting Lender.

(g)

Notwithstanding any provision in this Section 10.4 to the contrary, if any Lender becomes a Defaulting Lender, then

Section  1.5.

Survival.  All  covenants,  agreements,  representations  and  warranties  made  by  the  Borrower  herein  and  in  the
certificates or other instruments prepared or delivered in connection with or pursuant to this Agreement or any other Loan Document shall be
considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of any Loan Document and the
making of any Loans and the issuance of any Letter of Credit, regardless of any investigation made by any such other party or on its behalf
and notwithstanding that any Credit Party may have had notice or knowledge of any Default or incorrect representation or warranty at the
time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any
Loan or any LC Disbursement or any fee or any other amount payable under the Loan Documents is outstanding and unpaid or any Letter of
Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Sections 3.5, 3.6, 3.7, 10.3,  10.9,
10.10 and Article 9 shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby,
the  repayment  of  the  Loans  and  the  LC  Disbursements,  the  expiration  or  termination  of  the  Letters  of  Credit  and  the  termination  of  the
Commitments or the termination of this Agreement or any provision hereof.

Section 1.6.

Counterparts; Integration; Effectiveness.

(a)

This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of
which shall constitute an original, but all of which, when taken together, shall constitute a single contract. This Agreement and any separate
letter agreements with respect to fees payable to any Credit Party or the syndication of the credit facility established hereunder constitute the
entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral
or written, relating to the subject matter hereof. Except as provided in Section 5.1, this Agreement shall become effective as of the date set
forth in the preamble to this Agreement when it shall have been executed by the Administrative Agent and when the Administrative Agent
shall have received counterparts hereof which, when taken

744315352 11074672    71     ALLETE CREDIT AGREEMENT

together, bear the signatures of each of the other parties and thereafter shall be binding upon and inure to the benefit of the parties hereto and
their respective successors and assigns.

(b)

Delivery of an executed counterpart of a signature page of (x) this Agreement, (y) any other Loan Document and/or
(z) any document, amendment, approval, consent, information, notice (including, for the avoidance of doubt, any notice delivered pursuant to
Section  9.1),  certificate,  request,  statement,  disclosure  or  authorization  related  to  this  Agreement,  any  other  Loan  Document  and/or  the
transactions  contemplated  hereby  and/or  thereby  (each  an  “Ancillary Document”)  that  is  an  Electronic  Signature  transmitted  by  telecopy,
emailed pdf. or any other electronic means that reproduces an image of an actual executed signature page shall be effective as delivery of a
manually  executed  counterpart  of  this  Agreement,  such  other  Loan  Document  or  such  Ancillary  Document,  as  applicable.  The  words
“execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Agreement, any other Loan Document and/or
any  Ancillary  Document  shall  be  deemed  to  include  Electronic  Signatures,  deliveries  or  the  keeping  of  records  in  any  electronic  form
(including deliveries by telecopy, emailed pdf. or any other electronic means that reproduces an image of an actual executed signature page),
each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the
use of a paper-based recordkeeping system, as the case may be; provided that nothing herein shall require the Administrative Agent to accept
Electronic Signatures in any form or format without its prior written consent and pursuant to procedures approved by it; provided, further,
without limiting the foregoing, (i) to the extent the Administrative Agent has agreed to accept any Electronic Signature, each of the parties
hereto shall be entitled to rely on such Electronic Signature purportedly given by or on behalf of any other party without further verification
thereof and without any obligation to review the appearance or form of any such Electronic Signature and (ii) upon the request of any party,
any Electronic Signature shall be promptly followed by a manually executed counterpart. Without limiting the generality of the foregoing,
each  of  the  parties  hereby  (A)  agrees  that,  for  all  purposes,  including  without  limitation,  in  connection  with  any  workout,  restructuring,
enforcement of remedies, bankruptcy proceedings or litigation among the parties, Electronic Signatures transmitted by telecopy, emailed pdf.
or any other electronic means that reproduces an image of an actual executed signature page and/or any electronic images of this Agreement,
any other Loan Document and/or any Ancillary Document shall have the same legal effect, validity and enforceability as any paper original,
(B) may, at its option, create one or more copies of this Agreement, any other Loan Document and/or any Ancillary Document in the form of
an imaged electronic record in any format, which shall be deemed created in the ordinary course of such Person’s business, and destroy the
original paper document (and all such electronic records shall be considered an original for all purposes and shall have the same legal effect,
validity and enforceability as a paper record). The Borrower (I) waives any argument, defense or right to contest the legal effect, validity or
enforceability of this Agreement, any other Loan Document and/or any Ancillary Document based solely on the lack of paper original copies
of this Agreement, such other Loan Document and/or such Ancillary Document, respectively, including with respect to any signature pages
thereto and (II) waives any claim against any Applicable Parties for any Liabilities arising solely from the Administrative Agent’s and/or any
Lender’s  reliance  on  or  use  of  Electronic  Signatures  and/or  transmissions  by  telecopy,  emailed  pdf.  or  any  other  electronic  means  that
reproduces an image of an actual executed signature page, including any Liabilities arising as a result of the failure of the Borrower to use
any available security measures in connection with the execution, delivery or transmission of any Electronic Signature.

Section 1.7.

Severability. In  the  event  any  one  or  more  of  the  provisions  contained  in  this  Agreement  should  be  held  invalid,
illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any
way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in
and of itself affect the validity of such provision in any other jurisdiction). The parties shall endeavor in good faith negotiations to replace the
invalid,  illegal  or  unenforceable  provisions  with  valid  provisions  the  economic  effect  of  which  comes  as  close  as  possible  to  that  of  the
invalid, illegal or unenforceable provisions.

Section 1.8.

Right of Set-off. If an Event of Default shall have occurred and be continuing, and the acceleration of the obligations

owing in connection with the Loan Documents, or

744315352 11074672    72     ALLETE CREDIT AGREEMENT

at any time upon the occurrence and during the continuance of an Event of Default under paragraph (a) of Article 8, each of the Lenders and
their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable law, to set-off
and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time
owing by it to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing
under this Agreement and the other Loan Documents held by it, irrespective of whether or not it shall have made any demand therefor and
although  such  obligations  may  be  unmatured.  The  rights  of  each  of  the  Lenders  and  their  respective  Affiliates  under  this  Section  are  in
addition to other rights and remedies (including other rights of set-off) that it may have. Each Lender agrees promptly to notify the Borrower
and the Administrative Agent after any such set off and application made by such Lender, provided that the failure to give such notice shall
not affect the validity of such set off and application.

against the Borrower, or any of its property, in the courts of any jurisdiction.

(c)

The Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do
so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this
Agreement  or  the  other  Loan  Documents  in  any  court  referred  to  in  paragraph  (b)  of  this  Section.  Each  of  the  parties  hereto  hereby
irrevocably waives, to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance of such action

CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A)
CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR  OTHERWISE,  THAT  SUCH  OTHER  PARTY  WOULD  NOT,  IN  THE  EVENT  OF  LITIGATION,  SEEK  TO  ENFORCE  THE
FOREGOING  WAIVER  AND  (B)  ACKNOWLEDGES  THAT  IT  AND  THE  OTHER  PARTIES  HERETO  HAVE  BEEN  INDUCED  TO

or LC Disbursements or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with
interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender.

Section 1.13. Advertisement. The Borrower hereby authorizes JPMorgan Chase or any Affiliate thereof to publish the name of the

consented to such disclosure in writing.

Section  1.16. No  Fiduciary  Duty,  etc.  (a)  The  Borrower  acknowledges  and  agrees,  and  acknowledges  its  Subsidiaries’

understanding, that no Credit Party will have any obligations except

744315352 11074672    74     ALLETE CREDIT AGREEMENT

those obligations expressly set forth herein and in the other Loan Documents and each Credit Party is acting solely in the capacity of an arm’s
length contractual counterparty to the Borrower with respect to the Loan Documents and the transactions contemplated herein and therein
and not as a financial advisor or a fiduciary to, or an agent of, the Borrower or any other person. The Borrower agrees that it will not assert
any claim against any Credit Party based on an alleged breach of fiduciary duty by such Credit Party in connection with this Agreement and
the transactions contemplated hereby. Additionally, the Borrower acknowledges and agrees that no Credit Party is advising the Borrower as
to any legal, tax, investment, accounting, regulatory or any other matters in any jurisdiction. The Borrower shall consult with its own advisors
concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated
herein or in the other Loan Documents, and the Credit Parties shall have no responsibility or liability to the Borrower with respect thereto.

(b) The Borrower further acknowledges and agrees, and acknowledges its Subsidiaries’ understanding, that each Credit Party,
together with its Affiliates, is a full service securities or banking firm engaged in securities trading and brokerage activities as well as
providing investment banking and other financial services. In the ordinary course of business, any Credit Party may provide investment
banking and other financial services to, and/or acquire, hold or sell, for its own accounts and the accounts of customers, equity, debt and other
securities and financial instruments (including bank loans and other obligations) of, the Borrower and other companies with which the
Borrower may have commercial or other relationships. With respect to any securities and/or financial instruments so held by any Credit Party
or any of its customers, all rights in respect of such securities and financial instruments, including any voting rights, will be exercised by the
holder of the rights, in its sole discretion.

(c) In addition, the Borrower acknowledges and agrees, and acknowledges its Subsidiaries’ understanding, that each Credit Party and

its affiliates may be providing debt financing, equity capital or other services (including financial advisory services) to other companies in
respect of which the Borrower may have conflicting interests regarding the transactions described herein and otherwise. No Credit Party will
use confidential information obtained from the Borrower by virtue of the transactions contemplated by the Loan Documents or its other
relationships with the Borrower in connection with the performance by such Credit Party of services for other companies, and no Credit Party
will furnish any such information to other companies. The Borrower also acknowledges that no Credit Party has any obligation to use in
connection with the transactions contemplated by the Loan Documents, or to furnish to the Borrower, confidential information obtained from
other companies.

Section 1.17. CoBank Equity and Security.

(a)

So  long  as  CoBank  (or  its  Affiliate)  is  a  Lender  hereunder,  the  Borrower  will  (i)  maintain  its  status  as  an  entity
eligible to borrow from CoBank and (ii) acquire equity in CoBank in such amounts and at such times as CoBank may require in accordance
with  CoBank’s  Bylaws  and  Capital  Plan,  except  that  the  maximum  amount  of  equity  that  the  Borrower  may  be  required  to  purchase  in
CoBank in connection with the Loans made by CoBank (or its affiliate) may not exceed the maximum amount permitted by the Bylaws and
the Capital Plan at the time this Agreement is entered into. The Borrower acknowledges receipt of a copy of (x) CoBank’s most recent annual
report, and if more recent, CoBank’s latest quarterly report, (y) CoBank’s Notice to Prospective Stockholders and (iii) CoBank’s Bylaws and
Capital Plan, which describe the nature of all of the Borrower’s cash patronage, stock and other equities in CoBank acquired in connection
with its patronage loan from CoBank (or its Affiliate) (the “CoBank Equities”) as well as capitalization requirements, and agrees to be bound
by the terms thereof.

(b)

Each party hereto acknowledges that CoBank’s Bylaws and Capital Plan shall govern (i) the rights and obligations of
the parties with respect to the CoBank Equities and any patronage refunds or other distributions made on account thereof or on account of the
Borrower’s patronage with CoBank, (ii) the Borrower’s eligibility for patronage distributions from CoBank (in the form of CoBank Equities
and cash) and (iii) patronage distributions, if any, in the event of a sale of a participation interest. CoBank reserves the right to assign or sell

(c)

Each party hereto acknowledges that CoBank has a statutory first lien pursuant to the Farm Credit Act of 1971 (as
amended from time to time) on all CoBank Equities that the Borrower may now own or hereafter acquire, which statutory lien shall be for
CoBank’s (or its Affiliate’s) sole and exclusive benefit. The CoBank Equities shall not constitute security for the obligations due to any other
Lender. To the extent that any of the Loan Documents create a Lien on the CoBank Equities or on patronage accrued by CoBank for the
account of the Borrower (including, in each case, proceeds thereof), such Lien shall be for CoBank’s (or its Affiliate’s) sole and exclusive
benefit and shall not be subject to pro rata sharing hereunder. Neither the CoBank Equities nor any accrued patronage shall be offset against
the  obligations  hereunder,  except  that,  in  the  event  of  an  Event  of  Default,  CoBank  may  elect,  solely  at  its  discretion,  to  apply  the  cash
portion of any patronage distribution or retirement of equity to amounts owed to CoBank or its Affiliate under this Agreement, whether or
not  such  amounts  are  currently  due  and  payable.  The  Borrower  acknowledges  that  any  corresponding  tax  liability  associated  with  such
application is the sole responsibility of the Borrower. CoBank shall have no obligation to retire the CoBank Equities upon any Default or any
other default by the Borrower, or at any other time, either for application to the Loans or other obligations under this Agreement or otherwise.

Section  1.18. Acknowledgement  and  Consent  to  Bail-In  of  Affected  Financial  Institutions.  Notwithstanding  anything  to  the
contrary  in  any  Loan  Document  or  in  any  other  agreement,  arrangement  or  understanding  among  any  such  parties,  each  party  hereto
acknowledges that any liability of any Affected Financial Institution arising under any Loan Document may be subject to the Write-Down
and Conversion Powers of the applicable Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by:

liabilities arising hereunder which may be payable to it by any party hereto that is an EEA Financial Institution; and

(a)

the  application  of  any  Write-Down  and  Conversion  Powers  by  the  applicable  Resolution  Authority  to  any  such

(b)

the effects of any Bail-In Action on any such liability, including, if applicable:

(i)

a reduction in full or in part or cancellation of any such liability;

(ii)

a  conversion  of  all,  or  a  portion  of,  such  liability  into  shares  or  other  instruments  of  ownership  in  such
Affected Financial Institution, its parent entity, or a bridge institution that may be issued to it or otherwise conferred on it,
and that such shares or other instruments of ownership will be accepted by it in lieu of any rights with respect to any such
liability under this Agreement or any other Loan Document; or

(iii)

the variation of the terms of such liability in connection with the exercise of the Write-Down and Conversion

Powers of the applicable Resolution Authority.

ALLETE AND AFFILIATED COMPANIES

SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN II

Effective January 1, 2021

ARTICLE 1
Establishment, Purpose and Intent

1.1

Establishment.  This  document  includes  the  terms  of  the  ALLETE  and  Affiliated  Companies  Supplemental  Executive
Retirement  Plan  II.  The  purpose  of  SERP  II  is  to  provide  eligible  Employees  an  opportunity  to  elect  to  defer
compensation. SERP II also provides eligible Employees a supplemental Retirement Benefit designed to compensate for
annual compensation limits and maximum benefit limitations imposed by the Code on Retirement Plans maintained by
the Company.

SERP II is a successor to the ALLETE and Affiliated Companies Supplemental Executive Retirement Plan (“SERP I”).
On December 31, 2004, the Company froze SERP I with respect to all deferrals and vested accrued Retirement Benefits
(if  any).  On  January  1,  2005,  the  Company  established  SERP  II  to  govern  (a)  amounts  initially  deferred  after
December 31, 2004 and investment earnings thereon; (b) Retirement Benefit accruals after December 31, 2004; and (c)
accrued but unvested SERP I Retirement Benefits as of December 31, 2004. From January 1, 2005 to the effective date
hereof,  the  Company  operated  and  administered  the  Plan  in  all  material  respects  in  good  faith  compliance  with  the
applicable requirements of Section 409A, the final and proposed Treasury Regulations, IRS Notice 2005-1, and all other
IRS  guidance.  The  Company  amended  and  restated  SERP  II  in  its  entirety,  effective  January  1,  2009,  to  comply  with
Section 409A. The Company intends that SERP II constitute an unfunded deferred compensation plan for a select group
of management or highly compensated employees within the meaning of ERISA sections 201(2), 301(a)(3) and 401(a)(1).
All  provisions  of  SERP  II  shall  be  interpreted  and  administered  to  the  extent  possible  in  a  manner  consistent  with  the
stated intentions.

Effective January 20, 2009, the Company amended SERP II to narrow the salary-grade eligibility requirements to receive
an Annual Make-Up Award for employees who first became eligible to participate in SERP II after September 30, 2006.

Effective January 1, 2011, the Company amended SERP II to incorporate any compensation recovery policy adopted by
the Company and to provide that certain benefits may be subject to forfeiture for Misconduct.

Effective  January  1,  2015,  the  Company  amended  SERP  II  to  reflect  the  reduction  to  the  Flexible  Dollar  Makeup  in
connection with amendments to the ALLETE and Affiliated Companies Flexible Compensation Plan that eliminate the
life  insurance  percentage  (age-rated)  flexible  dollars  benefit  commencing  with  the  Plan  Year  that  begins  on  January  1,
2015.

Effective  January  1,  2019,  the  Company  hereby  amends  SERP  II  to  and  to  narrow  the  salary-grade  eligibility
requirements to defer compensation, to reflect the discontinuation of additional non-elective 162(m) Deferrals beginning
with the Plan Year that commences on January 1, 2019, to freeze credited service as of December 31, 2018, for

                                                 Exhibit 10(f)5

all Participants eligible for a SERP II Retirement Benefit, and to modify the amount of the Annual Make-up Award.

Effective January 1, 2021, the Company hereby amends SERP II to freeze final average earnings for Retirement Benefit
purposes as of the earlier of a Participant’s Separation from Service or December 31, 2021, and to clarify the Salary used
to determine Annual Make-up Awards.

Capitalized terms, unless otherwise defined herein, shall have the meaning provided in Appendix A.

1.2

Compensation Recovery Policy. All amounts payable to Participants in accordance with this Plan are subject to, and the
Company hereby incorporates into this SERP II, the terms of any compensation recovery policy or policies established
and amended by the Company from time to time (“Compensation Recovery Policy”).

ARTICLE 2
Section 409A Plans and Organization

1.1

Section 409A Plans. The provisions of SERP II include terms and conditions applicable to the following 409A Plans:

1.1.1 An elective account balance plan for Employees for purposes of Elective Deferrals;

1.1.2 A non-elective account balance plan for Employees for purposes of Non-Elective Deferrals; and

1.1.3 A non-account balance plan for Employees.

1.2

Organization. Except as otherwise provided in this section or in a specific section, all provisions of the Plan apply to all
amounts deferred under any Article of the Plan.

1.1.1 The provisions of Article 5 apply only for purposes of identifying employees eligible to receive an Annual Make-

Up Award and the amount of the award, if any.

1.1.2 The  provisions  of  Articles  6  and  7  apply  only  to  the  extent  that  SERP  II  provides  for  Employees’  Elective
Deferrals, or Non-Elective Deferrals or both, which, for purposes of Section 409A, represent the elective and non-
elective account balance plans identified in subsections 2.1.1 and 2.1.2, respectively.

1.1.3 The  provisions  of  Article  8  apply  only  to  the  extent  that  SERP  II  provides  for  Retirement  Benefits,  which

represent the non-account balance plan identified in subsection 2.1.3.

1.3

Section 409A Compliance. To the extent that any provision of the Plan would cause a conflict with the requirements of
Section  409A,  or  would  cause  the  administration  of  the  Plan  to  fail  to  satisfy  Section  409A,  such  provision  shall  be
deemed null and void to the extent permitted by applicable law. Nothing herein shall be construed as a guarantee of any
particular tax treatment to a Participant.

management  salary  grade  SG-SM  will  be  eligible  to  elect  to  make  elective  deferrals  in  accordance  with  this
Article 6.

1.1.2 Deferral Elections. For each Plan Year, an eligible Participant may elect to defer some or all of Salary, Bonus,
and,  if  eligible,  an  Annual  Make-up  Award,  Severance  Pay,  and  Other  Awards.  Elections  are  effective  on  a
calendar year basis and become irrevocable no later than the date specified by the Administrator, but in any event
before the beginning of the Plan Year to which the elections relate. An eligible Participant’s elections will become
effective  only  if  the  forms  required  by  the  Administrator  have  been  properly  completed  and  signed  by  the
Participant, timely delivered to the Administrator, and accepted by the Administrator. An eligible Participant who
fails to file elections before the required date will be treated as having elected not to defer any amounts for the
following Plan Year. For any Plan Year the Administrator may, in its sole discretion, decide not to allow one or
more Participants to defer certain types of compensation.

1.1.3 Special  Rule  for  Performance-Based  Compensation.  The  Administrator,  in  its  complete  and  sole  discretion,
may allow a Participant to revise a deferral election with respect to a Bonus if the Administrator determines that
the  Bonus  is  performance-based  compensation  within  the  meaning  of  Section  409A  and  the  election  becomes
irrevocable no later than the earlier of: (a) six months preceding the end of the performance period to which the
Bonus  relates;  or  (b)  the  date  as  of  which  the  Bonus  has  become  readily  ascertainable,  within  the  meaning  of
Section 409A.

1.1.4 Special Rule for Severance Pay. An eligible Participant may elect to defer all or a portion of Severance Pay by
filing with the Administrator an irrevocable deferral election no later than the date the Participant obtains a legally
binding right to the Severance Pay.

Administrator may, in its sole discretion, cancel the Participant’s deferral election, with respect to amounts to be
deferred on or after the cancellation, by the end of the year during which the Participant becomes disabled, or, if
later, the 15  day of the third month following the date on which the Participant becomes disabled. For purposes
of  this  Section,  a  Participant  shall  be  disabled  if  the  Participant  is  suffering  from  any  medically  determinable
physical or mental impairment resulting in the Participant’s inability to perform the duties of his position or any
substantially similar position, if such impairment can be expected to result in death or can be expected to last for a
continuous period of six months.

th

The Participant may elect to defer amounts for the Plan Year following his return to employment and for every
Plan Year thereafter while an Eligible Employee, provided the Participant’s deferral election otherwise complies

1.1.6 Cancellation of Deferral Election due to Unforeseeable Emergency. If  an  eligible Participant  experiences  an
Unforeseeable Emergency during a Plan Year, the Participant may submit to the Administrator a written request to
cancel  Elective  Deferrals  for  the  Plan  Year  to  satisfy  the  Unforeseeable  Emergency.  If  the  Administrator  either
approves  the  Participant’s  request  to  cancel  Elective  Deferrals  for  the  Plan  Year,  or  approves  a  request  for  a
distribution  of  in  accordance  with  Section  6.4.6,  then  effective  as  of  the  date  the  request  is  approved  the
Administrator  shall  cancel  the  Participant’s  deferral  elections  for  the  remainder  of  the  Plan  Year.  A  Participant
whose  Elective  Deferrals  are  canceled  during  a  Plan  Year  in  accordance  with  this  section  may  elect  Elective
Deferrals for the following Plan Year; provided, however, if required to comply with Treasury Regulations section
1.401(k)-1(d)(3), the Participant may not elect to defer any amounts attributable to periods less than six months
from the date on which the Participant receives a distribution on account of an Unforeseeable Emergency.

1.1.7 Withholding  of  Deferrals.  The  Administrator  will  withhold  Elective  Deferrals  not  later  than  the  end  of  the
calendar  year  during  which  the  Company  would  otherwise  have  paid  the  amounts  to  the  Participant  but  for  the
Participant’s deferral election. The Administrator will not withhold Elective Deferrals from a Participant’s Salary
during any period in which the Participant is on an unpaid leave of absence.

Non-Elective Deferrals. If  the  Administrator  determines  that  an  eligible  Participant’s  Salary  exceeds  the  Code  section
401(a)(17) limit, the Administrator shall automatically credit the Participant’s Annual Make-up Award to the Participant’s
Account

FICA and Other Taxes. For each Plan Year during which a Participant has Deferrals, the Participant’s Employer(s) shall,
in a manner determined by the Employer(s), withhold the Participant’s share of FICA and other required employment or
state, local, and foreign taxes on Deferrals from that portion of the Participant’s Salary, Bonus, Annual Make-up Award,
Severance Pay, Other Award and in the event of a 162(m) Deferral, the Participant’s compensation generally, that is not
deferred. To the extent permitted by Section 409A, the Administrator may reduce a Participant’s Deferrals to the extent
necessary to pay FICA and other employment, state, local and foreign taxes.

Distributions.  The  Plan  provides  for  distributions  in  a  Specified  Year,  or  upon  a  Separation  from  Service,  death,
Disability, or Unforeseeable Emergency. At the time of a Participant’s initial deferral election, a Participant may elect to
receive a distribution: (i) with respect to Elective Deferrals, in a Specified Year; and (ii) with respect to all Deferrals, upon
the earlier of Separation from Service, death or Disability. In each subsequent Plan year, a Participant may elect to have
all  or  any  portion  of  that  year’s  Elective  Deferrals  distributed  either  in  a  Specified  Year,  subject  to  the  restrictions  in
Section  6.4.1,  or  in  accordance  with  the  Participant’s  prior  elections  for  distributions  other  than  in  a  Specified  Year.
Except  as  otherwise  provided  in  the  Plan,  a  Participant’s  distribution  elections  are  irrevocable  and  will  govern  the
Deferrals  to  which  the  election  relates  until  the  amounts  covered  by  the  election  are  paid  in  full  or  until  subsequently
changed in accordance with Section 6.6. Notwithstanding any elections by a Participant, all distributions are subject to the
provisions of Sections 1.2 and 6.5.

1.1.1 Specified Year. A Participant may elect to receive a distribution of Elective Deferrals in a Specified Year, which
may  be  no  earlier  than  the  third  Plan  Year  beginning  after  the  date  on  which  the  Participant  initially  elects  to
receive a distribution in a Specified Year. Except as otherwise provided in this subsection

not elect to receive a distribution in a different Specified Year. Beginning during the year preceding any Specified
Year previously elected by the Participant, the Participant may elect to receive a distribution of Elective Deferrals
in  a  later  Specified  Year,  subject,  however,  to  the  restrictions  of  this  subsection.  All  amounts  distributed  in  a
Specified Year will be paid in a single lump sum.

1.1.2 Separation from Service. A Participant may elect to receive a distribution commencing either upon a Separation
from Service, or during any of the first five years following the year of the Separation from Service. A Participant

sum, monthly installments over a period of five (5), ten (10), or fifteen (15) years, or a combination of both a lump
sum  and  installments.  Notwithstanding  any  other  election  by  a  Participant  relating  to  a  distribution  upon
Disability, if a Participant dies after commencement of a Disability but before the year during which distributions
would  commence,  the  Participant’s  Account  shall  be  distributed  in  accordance  with  the  Participant’s  election
regarding distributions upon death.

1.1.4 Death. A  Participant  may  elect  to  receive  a  distribution  commencing  upon  death  or  during  any  of  the  first  five
years  following  the  year  of  death.  A  Participant  may  elect  to  receive  a  distribution  in  the  form  of  a  lump  sum,
monthly installments over a period of five (5), ten (10), or fifteen (15) years, or a combination of both a lump sum
and installments.

1.1.5 Unforeseeable  Emergency.  A  Participant  may  submit  a  written  request  for  a  distribution  on  account  of  an
Unforeseeable  Emergency.  Upon  approval  by  the  Administrator  of  a  Participant’s  request,  the  Participant’s
Account,  or  that  portion  of  a  Participant’s  Account  deemed  necessary  by  the  Administrator  to  satisfy  the
Unforeseeable Emergency (determined in a manner consistent with Section 409A) plus amounts necessary to pay
taxes reasonably anticipated because of the distribution, will be distributed in a single lump sum.

1.5

Additional Distribution Rules.

1.1.1 Default Time and Form of Distribution. If a Participant fails timely to elect a time and form of distribution, the

Event, and the Distribution Event occurs on or after October 1 of a Plan Year, the distribution may, to the extent
permitted  by  Section  409A,  commence  after  the  Distribution  Event  and  on  or  before  the  15   day  of  the  third
calendar month following the Distribution Event, even if after the end of the year during which the Distribution
Event  occurs;  provided,  however,  the  Participant  will  not  be  permitted,  directly  or  indirectly,  to  designate  the
taxable year of the distribution. If a Participant has elected to receive a distribution commencing during any of the
first five years following the year of a Distribution Event, the distribution will commence during the year elected
by  the  Participant.  If  a  Participant  has  elected  to  receive  a  distribution  in  a  Specified  Year,  the  distribution  will
occur during the Specified Year. Any distribution that complies with this section shall be deemed for all purposes
to comply with the Plan requirements regarding the time and form of distributions.

Installments. If a Participant elects to receive distributions in monthly installments, the Participant’s Account will
be paid in substantially equal monthly installments in consecutive years over the period elected by the Participant.
Each monthly installment will be paid during the Plan Year in which it is due, commencing as described in Section
6.5.2. During the Plan Year in which distributions commence, the Participant will receive one installment for each
calendar  month  beginning  after  the  date  of  the  Distribution  Event,  or,  if  the  Participant  has  elected  to  receive  a
distribution commencing during any of the first five years following the year of a Distribution Event, one monthly
installment for each calendar month beginning after the anniversary date of the Distribution Event. For  deferrals
made  in  connection  with  any  Plan  Year  that  commenced  on  or  before  January  1,  2018,  during  the  distribution
period, the Participant’s Account will be credited with interest compounded monthly at a rate of 7.5% per year.
For deferrals made in connection with any Plan Year that commences on or after January 1, 2019, the Participant’s
Account will be credited or debited with notional gains and losses based on the investment funds selected by the
Participant, from among the options provided by the Company, until all amounts credited have been distributed.
Any installment distribution that complies with this section shall be deemed for all purposes to comply with the
Plan requirements regarding the time and form of distributions.

1.1.4 Death  After  Commencement  of  Distributions.  Upon  the  death  of  a  Participant  after  distributions  of  the
Participant’s  Account  have  commenced,  the  balance  of  the  Participant’s  Account  will  be  distributed  to  the
Participant’s Beneficiary at the same times and in the same forms that the Account would have been distributed to
the Participant if the Participant had survived.

1.1.5 Distributions  to  Specified  Employees.  Notwithstanding  anything  to  the  contrary  in  this  Plan,  if  a  Participant
becomes entitled to a distribution on account of a Separation from Service and is a Specified Employee on the date
of the Separation from Service, distributions shall not commence until the earlier of: (i) the expiration of the six-
month period beginning on the date of Participant’s Separation from Service, or (ii) the date of Participant’s death.

1.1.6 Effect of Change in Control. Notwithstanding a Participant’s elections regarding distributions upon a Separation
from Service and a distribution in a Specified Year, if (a) the Participant has a Separation from Service within two
years following a Change in Control or (b) a Change in Control occurs within six months after the Participant has
a Separation from Service, the Participant shall receive a distribution of the Participant’s entire Account in a single
lump  sum  upon  the  later  of  the  Separation  from  Service  or  the  Change  in  Control,  whether  or  not  distributions
have already commenced.

Subsequent Changes in Time and Form of Distributions. A Participant may, in accordance with rules, procedures and
forms specified from time to time by the Administrator, elect to change the time of commencement or change the form in
which the Participant’s Account is distributed or both, provided that: (i) the Participant elects at least twelve (12) months
prior to the date on which payments are otherwise scheduled to commence; (ii) the new election does not take effect for at
least  twelve  (12)  months;  and  (iii)  with  respect  to  changes  applicable  to  distributions  in  a  Specified  Year  or  upon
Separation from Service, the distributions must be deferred for at least five (5) years from the date the distributions would
otherwise  have  been  paid,  or  in  the  case  of  installment  payments,  five  (5)  years  from  the  date  the  installments  were
scheduled  to  commence.  For  purposes  of  this  section,  distributions  on  account  of  a  Specified  Year  are  considered
scheduled to commence on January 1 of the Specified Year and all other distributions are considered to commence on the
date  of  the  Distribution  Event,  or  if  the  Participant  has  elected  a  later  year  for  commencement,  January  1  of  the  year
elected  by  the  Participant.  Any  election  in  accordance  with  this  section  to  change  the  time  or  form  or  both  shall  be
irrevocable on the date it is filed with the Administrator unless subsequently changed pursuant to this Section.

Accounts and Investments

Establishment  of  Accounts.  The  Company  will  establish  notional  accounts  for  each  Participant  as  the  Administrator
deems necessary or advisable from time to time. The Company will establish a Participant’s Account at the earlier of the
time a Participant first elects to defer any amounts into the Account or the time the Company first credits non-elective
amounts  to  the  Account.  Each  Account  shall  be  credited  as  appropriate  with  deferrals  and  earnings  with  respect  to
deferrals and debited for distributions from the Account.

Timing  of  Credits  to  Accounts.  The  Administrator  shall  credit  a  Participant’s  Elective  Deferrals  to  the  Participant’s
Account(s) not later than the end of the calendar year during which the Company would otherwise have paid the amounts
to the Participant but for the Participant’s deferral election. The Administrator shall credit Non-Elective Deferrals at such
times and in such amounts as the Administrator determines.

Vesting. All Participant Accounts are fully vested at all times.

Investments. The Administrator may select investment funds to use for measuring notional gains and losses credited or
debited to Participant’s Accounts. The Administrator will establish, from time to time, rules and procedures for allowing
each Participant who has not had a Distribution Event to designate which one or more of the selected investment funds
will  be  used  to  determine  the  notional  gains  and  losses  credited  or  debited  to  the  Participant’s  Accounts  prior  to
commencement of distributions.

who  were  not  Participants  on  that  date  are  not  eligible  for  Retirement  Benefits.  Any  Participant  who  was  accruing
Retirement Benefits on September 30, 2006 or who was eligible to accrue Retirement Benefits on that date because the
Participant received an Annual Incentive Award or Other Award and was serving in management salary grades SA – SM,
will  remain  eligible  for  Retirement  Benefits  in  accordance  with  this  section;  provided  the  Participant  remains  an
Employee of a Related Company.

Retirement; (ii) becoming Disabled after attaining both age 50 and 10 years of Vesting Service; or (iii) upon attaining age
50 and 10 years of Vesting Service after becoming Disabled. Participants will forfeit unvested Retirement Benefits and

Retirement Benefit. The  amount  of  the  Retirement  Benefit  shall  equal  a  single  life  annuity  determined  in  the  manner
provided  in  the  Retirement  Plans,  including  any  applicable  early  retirement  factors  and  cost  of  living  adjustments,  but
using a Participant’s Final Average Earnings and years of Credited Service as described in this section.

1.1.1 Final Average Earnings. As described herein, final Average Earnings shall be determined as of the earlier of the
Participant’s Separation from Service or December 31, 2021. Final Average Earnings include the sum of: (i) the
Participant’s four highest consecutive Annual Incentive Awards and Other Awards within the “applicable 15-year
period,” and (ii) the Participant’s highest Basic Compensation during any consecutive 48-month period within the
“applicable  15-year  period”  to  the  extent  that  Basic  Compensation  exceeds  the  limitation  on  compensation
imposed by Code section 401(a)(17). Compensation in excess of the limitation on compensation imposed by Code
section  401(a)(17)  shall  be  determined  by  using  the  limit  in  effect  on  the  first  day  of  the  48-month  period
described in (i) and the next three anniversaries of that date. With respect to a Participant who becomes entitled to
a distribution upon Retirement before December 31, 2021, the “applicable 15-year period” shall be the 15- year
period that ends on the date of Retirement. With respect to a Participant who becomes entitled to a distribution
upon Retirement on or after December 31, 2021, the “applicable 15-year period” shall be the 15-year period that
ends  on  December  31,  2021.  With  respect  to  a  Participant  who  becomes  entitled  to  a  distribution  because  of
Disability that occurs before December 31, 2021, the “applicable 15-year period” shall be the 15-year period that:
(i) ends no earlier than the Participant’s Disability and no later than the Participant’s sixty-fifth (65 ) birthday; and
(ii)  would  result  in  the  greatest  Retirement  Benefit.  With  respect  to  a  Participant  who  becomes  entitled  to  a
distribution because of a Disability that occurs on or after

Company  in  management  salary  grades  SA  –  SM;  and  (ii)  distributions  of  Retirement  Benefits  have  not
commenced. Notwithstanding the foregoing, no Participant will receive credit for years of Credited Service after
December 31, 2018.

1.4

Forfeiture of Vested Retirement Benefit for Misconduct. Notwithstanding any other term or condition in this Article 8,
a Participant will forfeit any vested Retirement Benefit attributable to any year during which the Participant engaged in
Misconduct  and  any  subsequent  period.  For  purposes  of  calculating  the  Retirement  Benefit  of  any  Participant  who
engaged in Misconduct, the Participant’s Final Average Earnings and Years of Credited Service will exclude the period
during which the Participant engaged in Misconduct and any subsequent period.

8.5        Time  and  Form  of  Distributions.  Subject  to  the  provisions  of  Section  8.6,  a  Participant  will  become  entitled  to  a
distribution of vested Retirement Benefits, in the form determined by this section, upon the earlier of: (i) Retirement; (ii)
Disability; or (iii) solely with respect to a Participant who vests after becoming Disabled, the earlier of death or attainment
of age 65.

8.5.1    Election of Alternative Forms of Distribution. A Participant may elect to receive the Retirement Benefit in one
of  the  following  forms,  each  of  which  shall  be  actuarially  equivalent:  (i)  monthly  installments  over  a  15-year
period, (ii) a monthly life annuity, (iii) a lump sum payment; or (iv) a combination of a lump sum and either (i) or
(ii). Actuarially equivalence will be calculated using actuarial factors adopted by the Administrator from time to
time. Effective as of December 31, 2008, Participant elections regarding the form of distribution are irrevocable
and will remain in effect until the Retirement Benefits are paid in full unless a Participant elects to change the time
and form of payment in accordance with Section 8.7.

8.5.2        Default  Form  of  Payment.  If  a  Participant  fails  to  elect  a  form  of  payment  with  respect  to  the  Participant’s
Retirement  Benefit  before  December  31,  2008,  the  Retirement  Benefit  will  be  paid  in  the  form  of  monthly
installments  over  a  15-year  period  unless  the  Participant  elects  to  change  the  time  and  form  of  payment  in
accordance with Section 8.7.

8.6    Additional Distribution Rules.

8.6.1        Commencement  of  Distributions.  Distributions  on  account  of  a  Distribution  Event  other  than  Disability  will
commence  between  the  date  of  the  Distribution  Event  and  the  end  of  the  year  in  which  the  Distribution  Event
occurs. If a Distribution Event other than Disability occurs on or after October 1 of a Plan Year, the distribution
may, to the extent permitted by Section 409A, commence after the Distribution Event and on or before the 15  day
of the third calendar month following the Distribution Event, even if after the end of the year during

th

12

        
                                                 Exhibit 10(f)5

which  the  Distribution  Event  occurs;  provided,  however,  the  Participant  will  not  be  permitted,  directly  or
indirectly, to designate the taxable year of the distribution. Any distribution that complies with this section shall be
deemed for all purposes to comply with the Plan requirements regarding the time and form of distributions.

8.6.2        Distributions  to  Specified  Employees.  Notwithstanding  anything  to  the  contrary  in  this  Plan,  if  a  Participant
becomes  entitled  to  a  distribution  on  account  of  a  Retirement  and  is  a  Specified  Employee  on  the  date  of  the
Retirement,  distributions  shall  not  commence  until  the  earlier  of:  (i)  the  expiration  of  the  six-month  period
beginning on the date of Participant’s Retirement, or (ii) the date of the Participant’s death. Payments to which a
Specified  Employee  would  otherwise  be  entitled  during  this  six-month  period  shall  be  accumulated  and  paid,
together with earnings (calculated using the interest rate adopted by the Administrator for determining actuarial
equivalence)  that  have  accrued  during  this  six-month  delay,  during  the  seventh  month  following  the  date  of  the
Participant’s Retirement, or, if earlier, the date of the Participant’s death.

8.6.3    Disability. Unless subsequently changed in accordance with the Plan, distributions on account of Disability will

commence on the earlier of the Participant’s 65  birthday or the second anniversary of the Disability.

th

8.6.4        Annuity  Payments  and  Installments.  If  a  Participant  elects  to  receive  all  or  a  portion  of  the  distributions  in
monthly  installments,  that  portion  to  be  paid  in  installments  will  be  paid  in  substantially  equal  monthly
installments in consecutive months over a 15-year period. If a Participant elects to receive all or a portion of the
distributions  in  the  form  of  a  life  annuity,  that  portion  to  be  paid  as  a  life  annuity  will  be  paid  in  monthly
installments  in  consecutive  months  for  the  remainder  of  the  Participant’s  life,  in  the  case  of  a  unmarried
Participant, and in the case of a married Participant over the lives of the Participant and the Participant’s Eligible
Surviving Spouse. Each monthly installment or life annuity payment will be paid during the Plan Year in which it
is  due,  commencing  as  described  in  Section  8.6.1.  During  the  Plan  Year  in  which  distributions  commence,  the
Participant will receive one installment or life annuity payment for each calendar month beginning after the date
of the Distribution Event. If the Participant has elected to be paid in installments, during the distribution period the
portion of the Participant’s Account to be paid in installments will be credited with interest compounded monthly
at the interest rate used by the Administrator to determine actuarial equivalence. Any  distribution  that  complies
with this section shall be deemed for all purposes to comply with the Plan requirements regarding the time and
form of distributions.

8.6.5    Death After Commencement of Benefits. Upon the death of a Participant after distributions of the Participant’s
Retirement  Benefit  have  commenced,  the  remainder  of  the  Participant’s  Retirement  Benefit  will  continue  to  be
distributed to the Participant’s Beneficiary at the same time and in the same form as the benefit would have been
distributed to the Participant had the Participant survived, except to the extent that the Participant had elected a life
annuity:  (i)  if  the  Participant  has  an  Eligible  Surviving  Spouse  on  the  date  of  death,  the  surviving  spouse  will
receive 60% of the Participant’s life annuity benefit for the remainder of the spouse’s life and (ii) if the Participant
does not have an Eligible Surviving Spouse, the annuity will cease as of the first day of the month following the
month during which the Participant died.

8.6.6        Effect  of  Change  of  Control.  With  respect  to  any  Participant  whose  Retirement  Benefit  distributions  have
commenced, or would commence, upon a Separation from Service, if (a) the Participant’s Separation from Service
occurs within two years following a Change in Control or (b) a Change in Control occurs within six months after
the Participant’s Separation from Service, then notwithstanding the Participant’s elections regarding distributions
upon  a  Separation  from  Service,  the  Participant  shall  receive  a  distribution  of  the  Participant’s  entire  remaining
vested Retirement Benefit in a single lump sum upon the later of the Separation from Service or the Change in
Control,  whether  or  not  distributions  have  already  commenced.  Any  Retirement  Benefit  that  does  not  become
payable  in  a  lump  sum  in  accordance  with  this  section  will  vest,  if  at  all,  in  accordance  with  Section  8.2,  will
become payable in accordance with Section 8.5, and will otherwise remain subject to the provisions of Article 8.

8.7    Subsequent Changes in Time and Form of Payment. A Participant may, in accordance with rules, procedures and forms
specified  from  time  to  time  by  the  Administrator,  elect  to  change  the  form  in  which  the  Participant’s  Retirement  Benefit  is
distributed, provided that: (i) the Participant elects at least twelve (12) months prior to the date on which payments are otherwise
scheduled  to  commence;  (ii)  the  new  election  does  not  take  effect  for  at  least  twelve  (12)  months;  and  (iii)  with  respect  to
changes applicable to distributions upon Retirement or, solely with respect to a Participant who vests after becoming Disabled,
distributions  upon  attaining  age  65,  distributions  must  be  deferred  for  at  least  five  years  from  the  date  the  distributions  would
otherwise  have  been  paid,  or  in  the  case  of  installment  payments  or  life  annuity  payments,  five  years  from  the  date  the
installments or life annuity payments were scheduled to commence. Any such election shall be irrevocable on the date it is filed
with  the  Administrator  unless  subsequently  changed  pursuant  to  this  section.  For  purposes  of  this  section,  distributions  are
considered to commence on the date of the Distribution Event.

8.8    FICA and Other Taxes. At the time of a Participant’s Distribution Event, the Participant’s Employer(s) shall, in a manner
determined by the Employer(s), calculate the FICA and other required employment or state, local, and foreign taxes due on the
lump sum present value, calculated using the factors adopted by the Administrator for determining actuarial equivalence, of the
Participant’s Retirement Benefit and shall reduce the Participant’s Retirement Benefit by the amount of any such taxes payable by
the Participant. The amount of the Participant’s Retirement Benefit remaining after reduction for any taxes shall be payable in
accordance with Sections 8.6 and 8.7.

ARTICLE 9
Payment Acceleration and Delay

1.1

Permitted  Accelerations  of  Payment.  Except  as  otherwise  provided  herein  or  permitted  by  Section  409A,  the  Plan
prohibits the acceleration of the time or schedule of any payment due under the Plan.

1.1.1 Distribution in the Event of Taxation. If, for any reason, all or any portion of any benefit provided by the Plan
becomes taxable to a Participant because of a violation of Section 409A prior to receipt, the Participant may file a
written request with the Administrator for a distribution of that portion of the Plan benefit that has become taxable.
Upon the grant of such a request, which grant shall not be unreasonably withheld, the Participant shall receive a
distribution equal to the taxable portion of the Plan benefit. If the request is granted, the tax liability distribution
shall be paid between the date on which the Participant’s request is approved and the end of the Plan Year during
which the approval occurred, or if

14

        
                                                 Exhibit 10(f)5

later, the 15  day of the third calendar month following the date on which the Participant’s request is approved.

th

1.1.2 Compliance  with  Ethics  Laws  or  Conflicts  of  Interests  Laws.  The  Administrator  is  authorized,  in  its  sole
discretion, to accelerate the time or schedule of a payment to the extent necessary to avoid the violation of any
applicable federal, state, local, or foreign ethics law or conflicts of interest law as provided in Section 409A.

1.1.3 Small  Accounts.  The  Administrator  may,  in  its  sole  discretion,  distribute  in  a  single  lump  sum  the  aggregate
amounts of Deferrals or Elective Deferrals or both credited to the Participant’s Account, along with any related
earnings, provided: (i) the distribution results in the payment of the Participant’s entire interest in the Account and
all  Aggregated  Plans,  and  (ii)  the  total  payment  does  not  exceed  the  applicable  dollar  limit  under  Code  section
402(g)(1)(B). The Administrator shall notify the Participant in writing if the Administrator exercises its discretion
pursuant to this Section.

1.1.4 Settlement of a Bona Fide Dispute. The Administrator may, in its sole discretion, accelerate the time or schedule
of a distribution as part of a settlement of a bona fide dispute between the Participant and the Employer over the
Participant’s  right  to  a  distribution  provided  that  the  distribution  relates  only  to  the  deferred  compensation  in
dispute and the Employer is not experiencing a downturn in financial health.

1.1.5 Settlement of Debt. The Administrator may, in its sole discretion, accelerate the time or schedule of a payment to
satisfy an ordinary debt owed by the Participant to the Employer at the time the debt becomes due as provided in
Section 409A.

1.2

Permissible Payment Delays. Notwithstanding anything in the Plan to the contrary, to the extent permitted by Section
409A, the Administrator may, in its sole discretion, delay a distribution to a Participant:

1.1.1

1.1.2

1.1.3

1.1.4

If  the  distribution  would  jeopardize  the  Employer’s  ability  to  continue  as  a  going  concern,  provided  that  the
delayed amount is distributed in the first calendar year in which the payment would not have such effect.

If the Company reasonably anticipates that its deduction with respect to a distribution, if paid as scheduled, could
be limited or barred by the application of Code section 162(m), provided the delayed amount is distributed in the
first calendar year in which the Company reasonably anticipates that the deduction would not be limited or barred
by the application of Code section 162(m).

If the distribution would violate Federal securities or other applicable laws, provided that the delayed amount is
distributed at the earliest date at which the Administrator reasonably anticipates that the distribution will not cause
such violation.

If  calculation  of  the  distribution  is  not  administratively  practicable  due  to  events  beyond  the  control  of  the
Participant, provided that the delayed amount is distributed in the first calendar year in which the calculation of
the distribution is administratively practicable.

1.3

Suspension  Not  Allowed.  If  a  Participant  whose  distributions  have  commenced  becomes  eligible  again  to  defer
compensation as a Participant in any plan subject to Section 409A maintained by a Related Company, distribution of the
Participant’s Retirement Benefit or Account may not be suspended.

ARTICLE 10
Beneficiary Designation

Beneficiary. Each  Participant  shall  have  the  right,  in  accordance  with  procedures  established  from  time  to  time  by  the
Administrator,  to  designate  a  Beneficiary(ies)  (both  primary  as  well  as  contingent)  to  whom  Plan  benefits  shall,  if
permitted by the Plan, be paid if a Participant dies prior to complete distribution of benefits. Each Beneficiary designation
shall be in a written form prescribed by the Administrator, and will be effective only when filed with the Administrator
during the Participant’s lifetime. Any Beneficiary designation may be changed by a Participant without the consent of the
previously  named  Beneficiary  by  filing  a  new  Beneficiary  designation  with  the  Administrator.  The  most  recent
Beneficiary designation received by the Administrator shall control the payment of all benefits under the Plan in the event
of the Participant’s death.

No Beneficiary Designation.  In  the  absence  of  an  effective  Beneficiary  designation,  or  if  all  designated  Beneficiaries
predecease the Participant or die prior to the complete distribution of the Participant’s benefits, benefits shall be paid in
the following order of precedence: (a) the Participant’s surviving spouse; (b) the Participant’s children (including adopted
children), per stirpes; or (c) the Participant’s estate.

ARTICLE 11
Claims Procedures

Presentation of Claim. Any Participant or Beneficiary of a deceased Participant (such Participant or Beneficiary being
referred  to  below  as  a  “Claimant”)  may  file  with  the  Administrator  a  written  claim  for  a  determination  with  respect  to
Plan benefits. The claim must state with particularity the determination desired by the Claimant.

Notification of Decision. The Administrator shall consider a Claimant’s claim, and, except as provided below, within 90
days after the claim is received, shall notify the Claimant in writing:

1.1.1 That the claim has been allowed in full; or

1.1.2 That the claim has been denied, in whole or in part, and such notice must set forth in a manner calculated to be

understood by the Claimant:

(a)

(b)

(c)

The specific reason(s) for the denial of the claim, or any part of it;

Specific reference(s) to pertinent provisions of the Plan upon which such denial was based;

A description of any additional material or information necessary for the Claimant to perfect the claim, and
an explanation of why such material or information is necessary; and

1.1.3

1.1.4

1.1.5

If the Administrator determines that an extension of time for processing is required, written notice of the extension
shall  be  furnished  to  the  Claimant  prior  to  termination  of  the  original  90-day  period.  In  no  event  shall  such
extension exceed 90 days from the end of such initial period.

In  the  case  of  a  claim  for  disability  benefits,  the  Administrator  shall  notify  the  Claimant,  in  accordance  with
subsection  11.2.2  above,  within  45  days  after  the  claim  is  received.  The  notification  shall  advise  the  Claimant
whether  the  Administrator’s  denial  relied  upon  any  specific  rule,  guideline,  protocol  or  scientific  or  clinical
judgment.

In  the  case  of  a  claim  for  disability  benefits,  if  the  Administrator  determines  that  an  extension  of  time  for
processing  is  required  due  to  matters  beyond  the  control  of  the  Plan,  written  notice  of  the  extension  shall  be
furnished to the Claimant prior to termination of the original 45-day period. Such extension shall not exceed 30
days from the end of the initial period. If, prior to the end of the first 30-day extension period, the Administrator
determines that, due to matters beyond the control of the Plan, an additional extension of time for processing is
required, written notice of a second 30-day extension shall be furnished to the Claimant prior to termination of the
first 30-day extension.

1.3

Review of a Denied Claim. Within 90 days after receiving a notice from the Administrator that a claim has been denied,
in whole or in part, a Claimant (or the Claimant’s duly authorized representative) may file a written request for a review
of the denial of the claim and of pertinent documents. The Claimant (or the Claimant’s duly authorized representative):

1.1.1 May  request  reasonable  access  to,  and  copies  of,  all  documents,  records,  and  other  information  relevant  to  the

claim, which shall be provided to Claimant free of charge; and

1.1.2 May submit written comments or other documents.

1.4

Decision  on  Review.  The  Administrator  shall  review  all  comments  or  other  documents  submitted  by  the  Claimant
relating  to  the  claim,  without  regard  to  whether  such  information  was  submitted  or  considered  in  the  initial  benefit
determination. The Administrator shall render its decision on review promptly, and not later than 60 days after the filing
of a written request for review of the denial (or, if other special circumstances require additional time and written notice
of such extension and circumstances is given to the Claimant within the initial 60-day period). The Administrator shall
notify the Claimant, in language calculated to be understood by the Claimant:

1.1.1 That the claim has been allowed in full; or

1.1.2 That the claim has been denied, in whole or in part, and such notice must set forth:

Such other matters as the Administrator deems relevant.

1.1.3

In the case of a claim for disability benefits, the notice shall set forth:

(a) Whether  the  Administrator’s  denial  relied  upon  any  specific  rule,  guideline,  protocol  or  scientific  or

clinical judgment; and

(b)

The  following  statement:  “You  and  your  Plan  may  have  other  voluntary  alternative  dispute  resolution
options,  such  as  mediation.  One  way  to  find  out  what  may  be  available  is  to  contact  your  local  U.S.
Department of Labor Office and your State insurance regulatory agency.”

1.5

Other Remedies. A  Claimant’s  compliance  with  the  foregoing  procedures  is  a  mandatory  prerequisite  to  a  Claimant’s
right to pursue any other remedy with respect to any claim relating to this Plan.

ARTICLE 12
Amendment or Termination

The Company hereby reserves the right to amend, modify, or terminate any one or more of the 409A Plans, at any time by
action  of  the  Board,  with  or  without  prior  notice.  No  amendment  or  termination  shall  reduce  any  Participant’s  Account  or
Retirement Benefit without the written consent of the affected Participant. Notwithstanding anything herein to the contrary, to the
extent  consistent  with  Section  409A,  the  Board  may  terminate  the  Plan  and  distribute  to  each  Participant  the  Participant’s
Account and the Participant’s Retirement Benefit, if any, in a lump sum; provided that all distributions (i) commence no earlier
than the date that is twelve (12) months following the termination date (or any earlier date that would comply with Section 409A)
and (ii) are completed by the date that is twenty-four (24) months following the termination date (or any later date that would
comply with Section 409A). In addition, payments may be accelerated upon termination of any 409A Plan only if, to the extent
required  under  Section  409A,  (i)  the  Company  terminates  all  Aggregated  Plans,  and  (ii)  for  three  years  following  the  date  of
termination of the 409A Plan, the Company does not adopt any new arrangement that would have been an Aggregated Plan of the
terminated 409A Plan.

ARTICLE 13
Miscellaneous Provisions

1.1

Unsecured General Creditor. Participants and their Beneficiaries, heirs, successors and assigns shall have no legal or
equitable rights, interests or claims in any property or assets of an Employer. An  Employer’s obligation  under  the  Plan
shall be merely that of an unfunded and unsecured promise to pay money in the future.

1.7

1.8

Employer’s Liability. An Employer’s liability for benefits shall be defined only by the Plan. An Employer shall have no
obligation to a Participant except as expressly provided in the Plan.

Nonassignability.  Neither  a  Participant  nor  any  other  person  shall  have  any  right  to  commute,  sell,  assign,  transfer,
pledge, anticipate, mortgage or otherwise encumber, transfer, hypothecate, alienate or convey in advance of actual receipt,
the amounts, if any, payable hereunder, or any part thereof, which are, and all rights to which are expressly declared to be,
unassignable and non-transferable. No part of the amounts payable shall, prior to actual payment, be subject to seizure,
attachment, garnishment or sequestration for the payment of any debts, judgments, alimony or separate maintenance owed
by  a  Participant  or  any  other  person,  be  transferable  by  operation  of  law  in  the  event  of  a  Participant’s  or  any  other
person’s bankruptcy or insolvency or be transferable to a spouse as a result of a property settlement or otherwise.

No Right to Employment. Nothing contained in this Plan or any documents relating to the Plan shall: (a) confer on a
Participant  any  right  to  continue  in  the  employ  of  a  Related  Company,  (b)  constitute  any  contract  or  agreement  of
employment,  (c)  interfere  with  the  right  of  a  Related  Company  to  terminate  the  Participant’s  employment  at  any  time,
with or without cause.

Incompetency.  If  the  Administrator  determines  that  a  distribution  under  this  Plan  is  to  be  paid  to  a  minor,  a  person
declared incompetent or to a person incapable of handling the disposition of that person’s property, the Administrator may
direct  such  distribution  to  be  paid  to  the  guardian,  legal  representative  or  person  having  the  care  and  custody  of  such
minor,  incompetent  or  incapable  person.  The  Administrator  may  require  proof  of  majority,  competence,  capacity,
guardianship,  or  status  as  a  legal  representative  as  it  may  deem  appropriate  prior  to  distribution  of  a  payment.  Any
distribution shall be a payment for the account of the Participant and the Participant’s Beneficiary, as the case may be, and
shall be a complete discharge of any liability for such payment amount.

Tax Withholding. To the extent required by the law in effect at the time of any distribution, the Participant’s Employer
shall withhold from any payments to a Participant hereunder any taxes required to be withheld by the federal or any state
or local government, in amounts and in a manner to be determined in the sole discretion of the Employer(s).

Furnishing Information. A Participant or his Beneficiary will cooperate with the Administrator by furnishing any and all
information  requested  by  the  Administrator  and  take  such  other  actions  as  may  be  requested  in  order  to  facilitate  the
administration of the Plan and the distributions hereunder, including but not limited to taking such physical examinations
as the Administrator may deem necessary.

Notice. Any notice or filing required or permitted under the Plan shall be sufficient if in writing and if (i) hand-delivered
or sent by telecopy, (ii) sent by registered or certified mail, or (iii) sent by nationally-recognized overnight courier. Such
notice shall be deemed given as of (i) the date of delivery if hand-delivered or sent by telecopy, (ii) as of the date shown
on the postmark on the receipt for registration or certification, if delivery is by mail, or (iii) on the first business day after
dispatch, if sent by nationally-recognized overnight courier.

construction of any of the terms or provisions of this Plan.

1.11 Applicable Law and Construction. The Plan shall be governed by, construed and administered in accordance with the
applicable  provisions  of  ERISA,  and  any  other  applicable  Federal  law,  including  Section  409A,  and  to  the  extent  not
preempted by Federal law, this Plan shall be governed by, construed and administered in accordance with the laws of the
State of Minnesota, other than its laws respecting choice of law.

1.12

1.13

Invalid or Unenforceable Provisions. If any provision of this Plan shall be held invalid or unenforceable, such invalidity
or unenforceability shall not affect any other provisions hereof and the Administrator may elect in its sole discretion to
construe such invalid or unenforceable provisions in a manner that conforms to applicable law or as if such provisions, to
the extent invalid or unenforceable, had not been included.

Successors.  This  Plan  shall  bind  any  successor  (whether  direct  or  indirect,  by  purchase,  merger,  consolidation  or
otherwise) to all or substantially all of the business or assets of the Company, in the same manner and to the same extent
that the Company would be obligated under this Plan if no succession had taken place. In the case of any transaction in
which a successor would not by the foregoing provision or by operation of law be bound by this Plan, the Company shall
require such successor expressly and unconditionally to assume and agree to perform the obligations of the Company and

Benefit Plans Committee.

“Aggregated Plans” means, with respect to any 409A Plan, that plan and all other non-qualified deferred compensation

plans which must be aggregated with that plan in accordance with the plan aggregation rules of Section 409A.

“Annual  Incentive  Award”  means  the  annual  award  received  by  a  Participant  under  the  ALLETE  Executive  Annual

Incentive Plan or any predecessor or successor plan.

“Basic Compensation” shall have the meaning prescribed in Retirement Plan A except:(1) Basic Compensation shall be
calculated without regard to the limitation on compensation imposed by Code section 401(a)(17); and (2) for Retirement Benefit
purposes, only compensation earned through December 31, 2021 shall be considered.

“Beneficiary”  means  one  or  more  persons,  trusts,  estates  or  other  entities,  designated  in  accordance  this  Plan,  that  are

addition to the Participant’s Salary.

“Change in Control” means the earliest of:

the  date  any  one  Person,  or  more  than  one  Person  acting  as  a  group  (as  the  term  “group”  is  used  in
Treasury Regulations section 1.409A-3(i)(5)(v)(B)), acquires ownership of stock of the Company that,
together  with  stock  previously  held  by  the  acquirer,  constitutes  more  than  fifty  (50%)  percent  of  the
total fair market value or total voting power of Company stock. If any one Person, or more than one
Person acting as a group, is considered to own more than fifty (50%) percent of the total fair market
value or total voting power of Company stock, the acquisition of additional stock by the same Person
or Persons acting as a group does not cause a Change in Control. An increase in the percentage of stock
owned by any one Person, or Persons acting as a group, as a result of a transaction in which Company
acquires its stock in exchange for property, is treated as an acquisition of stock;

21

month period ending on the date of the most recent acquisition by that Person or Persons) ownership of
Company stock possessing at least thirty (30%) percent of the total voting power of Company stock;

the members of the board of directors prior to the date of appointment or election; or

month period ending on the date of the most recent acquisition by that Person or Persons) assets from

22

impaired within the scope of employment or another serious driving offense committed within the scope of employment.

For  purposes  of  clarifying  the  foregoing  definition,  Misconduct  can  occur  regardless  of  whether  the  Company  discovers  the

from Service on account of the Misconduct.

“Non-Elective  Deferrals”  means  162(m)  Deferrals  and  the  Annual  Make-up  Award  credited  to  the  Account  of  any

ANNEX A
TO
ALLETE
EXECUTIVE LONG-TERM INCENTIVE COMPENSATION PLAN
RESTRICTED STOCK UNIT GRANT

The grant of restricted stock units (each, a “RSU”) under the ALLETE Executive Long-Term Incentive Compensation Plan (the
“Plan”), evidenced by the Grant to which this is annexed, is subject to the following additional terms and conditions:

1. Form and Timing of Payment. Subject to the provisions hereof, each RSU will be paid in the form of one share of ALLETE
common stock (each, a “Share”), plus accrued Dividend Equivalents. Shares will be deposited into your ALLETE Invest Direct
plan account. Except as otherwise provided in sections 3 and 4, below, payment will be made during the period ending sixty days
after the end of the vesting period; provided, however, the Participant will not be permitted, directly or indirectly, to designate the
taxable year of the distribution. Payment will be subject to withholding Shares equal in value to the minimum amount of tax
required to be withheld by law.

2. Dividend Equivalents. You will receive Dividend Equivalents in connection with the RSUs granted. Dividend Equivalents will
be calculated and credited to you at the time the underlying RSUs are paid. Dividend Equivalents will be in the form of additional
RSUs, which will be added to the number of RSUs subject to the grant, and will equal the number of Shares (including fractional
Shares) that could have been purchased on applicable dividend payment dates, based on the closing ALLETE common stock
price as reported in the consolidated transaction reporting system on that date, with cash dividends that would have been paid on
the underlying RSUs, if such RSUs were Shares. Dividend Equivalents will only become payable if and to the extent the
underlying RSUs vest and become payable.

3. Payment Upon Retirement, Death or Disability; Forfeiture Upon Other Termination of Employment, Default on Certain
Agreements or Unsatisfactory Job Performance.

3.1 Subject to Section 3.4 below, if during the vesting period you (i) Retire, (ii) die while employed by a Related

Company, or (iii) become Disabled, a portion of the unvested RSUs subject to the Grant will vest and be paid to you (or your
beneficiary or estate) during the period ending sixty days after such event; provided, however, you will not be permitted, directly
or indirectly, to designate the taxable year of the distribution. Except as otherwise provided in Section 4, payment pursuant to this
Section 3.1 will be prorated, after giving effect to accumulated Dividend Equivalents, based on the number of whole calendar
months within the vesting period that had elapsed as of the date of Retirement, death or Disability in relation to the number of
calendar months in the vesting period. For purposes of this calculation, you will be credited with a whole month if you were
employed on the 15  of the month.

th

3.2 Except as otherwise provided in Section 4, if during the vesting period or prior to payment of all RSUs you have a
Separation from Service for any reason other than those specified in Section 3.1 above, all unvested or unpaid RSUs subject to
the Grant (and related Dividend Equivalents) will be forfeited on the date of such Separation from Service.

3.3 If during the vesting period or prior to payment of all RSUs you are demoted, you default on any written agreement
with a Related Company related to a restrictive employment covenant (such as confidentiality, non-disclosure, non-competition,
non-solicitation, or the like), or if ALLETE determines, in its sole discretion, that your job performance is unsatisfactory,
ALLETE may cancel or amend your

2

Exhibit 10(i)17

grant relating to any unpaid RSUs, resulting in the forfeiture of some portion or all of your unpaid RSUs (and related Dividend
Equivalents).

3.4 Notwithstanding anything herein to the contrary, if you become entitled to a payment of the RSUs by reason of your

Retirement and if you are a Specified Employee on the date of such Retirement, payment shall not be made until the earlier of: (i)
the expiration of the six-month period beginning on the date of your Retirement, or (ii) the date of your death. The payment to
which a Specified Employee would otherwise be entitled during this six-month period shall be paid, together with Dividend
Equivalents that have accrued during this six-month delay, during the seventh month following the date of the Participant’s
Retirement, or, if earlier, the date of the Participant’s death.

4. Change in Control. Upon a Change in Control, unless the Committee provides otherwise prior to the Change in Control,
outstanding unvested RSUs shall be prorated (as described below) and such prorated RSUs shall immediately vest and be payable
to you during the period ending sixty days after the Change in Control. The RSUs will not be subject to proration and
immediately vest, however, if and to the extent that the Grant is, in connection with the Change in Control, fully assumed by the
successor corporation or parent thereof; in such case, the RSUs shall be prorated and immediately vest upon your termination of
employment by the successor corporation for reasons other than cause within 18 months following the Change in Control and be
payable to the Participant during the period ending sixty days after the termination of employment. Any payment on account of
or in connection with a Change in Control will be prorated, after giving effect to the accumulation of Dividend Equivalents,
based on the number of whole calendar months within the vesting period that had elapsed as of the date of the Change in Control
or termination of employment, as applicable, in relation to the number of calendar months in the vesting period. For purposes of
this calculation, you will be credited with a whole month if you were employed on the 15  of the month. In no event will you be
permitted, directly or indirectly, to designate the taxable year of the distribution on account of or in connection with a Change in
Control.

th

5. Compensation Recovery Policy. The Grant is subject to the terms of any compensation recovery policy or policies established
by ALLETE as may be amended from time to time (“Compensation Recovery Policy”). ALLETE hereby incorporates into the
Grant the terms of the Compensation Recovery Policy.

6. Section 409A Compliance. This Grant is intended to comply with Section 409A or an exemption thereunder, and, accordingly,
to the maximum extent permitted, the Plan and the Grant shall be interpreted and administered in compliance therewith.
Notwithstanding any other provision of the Grant, payments provided pursuant to the Grant may only be made upon an event and
in a manner that complies with Section 409A or an applicable exemption. Any payments pursuant to the Grant that may be
excluded from Section 409A as a short-term deferral shall be excluded from Section 409A to the maximum extent possible. To
the extent that any provision of the Grant would cause a conflict with the requirements of Section 409A or would cause the
administration of the Grant to fail to satisfy Section 409A, such provision shall be deemed null and void to the extent permitted
by applicable law. Nothing herein shall be construed as a guarantee of any particular tax treatment. ALLETE makes no
representation that the Grant complies with Section 409A and in no event shall ALLETE be liable for the payment of any taxes
and penalties that you may incur under Section 409A.
7. Claims Procedure and Arbitration. The Grant is subject to the following claims procedures:

7.1 Mandatory Claims Procedures. If you or any person acting on your behalf (the “Claimant”) has any claim or dispute
related in any way to the Grant or to the Plan, the Claimant must follow these claims procedures. All claims must be brought no
later than one year following the date on which the claim first arose and any claim not submitted within such time limit will be
waived.

delegate, shall notify the Claimant of the resolution of the Claim within 90 days after receipt of the claim; provided, however, if
the Claims Administrator determines that an extension is necessary, the 90-day period shall be extended to up to 180 days upon
notice to that effect to the Claimant.

7.3 Notice of Denial. If a claim is wholly or partially denied, the denial notice shall contain (i) the reason or reasons for

denial of the claim, and (ii) references to the pertinent Plan provisions upon which the denial is based. Unless the claim is
submitted for arbitration as provided below and in the Plan, the Claims Administrator’s decision or action shall be final,
conclusive and binding on all persons having any interest in the Plan.

7.4 Arbitration. If, after exhausting the procedures set forth above, a Claimant wishes to pursue legal action, any action by

the Claimant with respect to a claim, must be resolved by arbitration in the manner described herein.

a. Time Limits. A Claimant seeking arbitration of any determination by the Claims Administrator must, within six (6)
months of the date of the Claims Administrator’s final decision, file a demand for arbitration with the American

accordance with this Section.

Rules of the American Arbitration Association.

c. Venue. The arbitration shall be conducted in Minneapolis, Minnesota.

Claim relating to your Grant, agree to waive any right to sue in court or to pursue any other legal right or remedy that
might otherwise be available in connection with the resolution of the Claim.

e. Enforceability. Judgment upon any award entered by an arbitrator may be entered in any court having jurisdiction over

the parties.

f. Waiver of Class, Collective, and Representative Actions. Any claim shall be heard without consolidation of such claims
with any other person or entity. To the fullest extent permitted by law, whether in court or in arbitration, by participating
in the Plan, you waive any right to commence, be a party to in any way, or be an actual or putative class member of any
class, collective, or representative action arising out of or relating to any claim, and you agree that any claim may only be
initiated or maintained and decided on an individual basis.

g. Standard of Review. Any decision of an arbitrator on a claim shall be limited to determining whether the Claims

Administrator’s decision or action was arbitrary or capricious or was unlawful. The arbitrator shall adhere to and apply
the deferential standard of review set out in Conkright v. Frommert, 130 S. Ct. 1640 (2010), Metropolitan Life Insurance

Exhibit 10(i)17

1. Arbitration Rules. The arbitration hearing will be conducted under the AAA Commercial Arbitration Rules (as

amended or revised from time to time by AAA) (hereinafter the “AAA Rules”), before one AAA arbitrator who is
from the Large, Complex Case Panel and who has experience with matters involving executive compensation and
equity compensation plans. The AAA Rules and the terms and procedures set forth here may conflict on certain
issues. To the extent that the procedures set forth here conflict with the AAA Rules, the procedures set forth here
shall control and be applied by the arbitrator. Notwithstanding the amount of the claim, the Procedures for Large,
Complex Commercial Disputes shall not apply.

2. Substantive Law. The arbitrator shall apply the substantive law (and the laws of remedies, if applicable), of

Minnesota or federal law, or both, depending upon the claim. Except to the extent required by applicable law, the
Claimant shall keep any arbitration decision or award strictly confidential and not disclose to anyone other than his or
her spouse, attorney, or tax advisor.

3. Authority. The arbitrator shall have jurisdiction to hear and rule on prehearing disputes and is authorized to hold
prehearing conferences by telephone or in person as the arbitrator deems necessary. The arbitrator will have the
authority to hear a motion to dismiss and/or a motion for summary judgment by any party and in doing so shall apply
the standards governing such motions under the Federal Rules of Civil Procedure.

4. Pre-Hearing Procedures. Each party may take the deposition of not more than one individual and the expert witness,
if any, designated by another party. Each party will have the right to subpoena witnesses in accordance with the
Federal Arbitration Act, Title 9 of the United States Code. Additional discovery may be had only if the arbitrator so
orders, upon a showing of substantial need.

5. Fees and Costs. Administrative arbitration fees and arbitrator compensation shall be borne equally by the parties, and

each party shall be responsible for its own attorney’s fees, if any; provided, however, that the Committee will
authorize payment by the Company of all administrative arbitration fees, arbitrator compensation and attorney’s fees
if the Committee concludes that a Claimant has substantially prevailed on his or her claims. Unless prohibited by
statute, the arbitrator shall assess attorney’s fees against a party upon a showing that such party’s claim, defense or
position is frivolous, or unreasonable, or factually groundless. If either party pursues a claim by any means other than
those set forth in this Article, the responding party shall be entitled to dismissal of such action, and the recovery of all
costs and attorney’s fees and losses related to such action, unless prohibited by statute.

a.

Interstate Commerce and the Federal Arbitration Act. The Company is involved in transactions involving interstate
commerce, and the employee’s employment with the Company involves such commerce. Therefore, the Federal
Arbitration Act, Title 9 of the United States Code, will govern the interpretation, enforcement, and all judicial proceedings
regarding the arbitration procedures in this Section.

8. Ratification of Actions. By receiving the Grant or other benefit under the Plan, you and each person claiming under or through
you shall be conclusively deemed to have indicated your acceptance and ratification of, and consent to, any action taken under
the Plan or the Grant by ALLETE, the Board, or the Committee.

9. No Impact on Other Benefits. The Grant or payment on account thereof shall not be taken into account in determining any
benefits under any severance, retirement, welfare, insurance or other benefit

5

Exhibit 10(i)17

plan of ALLETE or any affiliate except to the extent otherwise expressly provided in writing in such other plan or an agreement
thereunder.

10. Notices. Any notice hereunder to ALLETE shall be addressed to ALLETE, 30 West Superior Street, Duluth, Minnesota
55802, Attention: Director – Human Resources, and any notice hereunder to you shall be directed to your address as indicated by
ALLETE’s records, subject to the right of either party to designate at any time hereafter in writing some other address.

11. Governing Law and Severability. To the extent not preempted by the Federal law, the Grant will be governed by and
construed in accordance with the laws of the State of Minnesota, without regard to its conflicts of law provisions. In the event any
provision of the Grant shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts
of the Grant, and the Grant shall be construed and enforced as if the illegal or invalid provision had not been included.

12. Definitions. Capitalized terms not otherwise defined herein shall have the meanings given them in the Plan. The following
definitions apply to the Grant and this Annex A:

12.1 “Claims Administrator” means ALLETE’s Chief Executive Officer, unless the claimant is (or is acting on behalf

of) an ALLETE executive officer (within the meaning of Exchange Act Rule 3b-7), in which case the Claims Administrator is the
Executive Compensation Committee of the Board of Directors.

12.2 “Change in Control” means the earliest of:

i.

ii.

iii.

iv.

the date any one Person, or more than one Person acting as a group (as the term “group” is used in Treasury
Regulations section 1.409A-3(i)(5)(v)(B)), acquires ownership of stock of the Company that, together with
stock previously held by the acquirer, constitutes more than fifty (50%) percent of the total fair market
value or total voting power of Company stock. If any one Person, or more than one Person acting as a
group, is considered to own more than fifty (50%) percent of the total fair market value or total voting
power of Company stock, the acquisition of additional stock by the same Person or Persons acting as a
group does not cause a Change in Control. An increase in the percentage of stock owned by any one Person,
or Persons acting as a group, as a result of a transaction in which Company acquires its stock in exchange
for property, is treated as an acquisition of stock;

the date any one Person, or more than one Person acting as a group (as the term “group” is used in Treasury
Regulations section 1.409A-3(i)(5)(v)(B)), acquires (or has acquired during the twelve (12) month period
ending on the date of the most recent acquisition by that Person or Persons) ownership of Company stock
possessing at least thirty (30%) percent of the total voting power of Company stock;

the date a majority of the members of the Company’s board of directors is replaced during any twelve (12)
month period by directors whose appointment or election is not endorsed by a majority of the members of
the board of directors prior to the date of appointment or election; or

the date any one Person, or more than one Person acting as a group (as the term “group” is used in Treasury
Regulations section 1.409A-3(i)(5)(v)(B)), acquires (or has acquired during the twelve (12) month period
ending on the date of the most recent acquisition by that Person or Persons) assets from the Company that
have a total gross fair market value equal to at least forty (40%) percent of the total gross fair market value
of all the Company’s assets immediately prior to the acquisition or acquisitions. For this purpose, “gross fair
market value” means the value of the

6

Exhibit 10(i)17

corporation’s assets, or the value of the assets being disposed of, without regard to any liabilities associated
with these assets.

In determining whether a Change in Control occurs, the attribution rules of Code section 318 apply to determine stock
ownership. The stock underlying a vested option is treated as owned by the individual who holds the vested option, and the stock
underlying an unvested option is not treated as owned by the individual who holds the unvested option. The term “Person” used
in this definition means any individual, corporation (including any non-profit corporation), general, limited or limited liability
partnership, limited liability company, joint venture, estate, trust, firm, association, organization or other entity or any
governmental or quasi-governmental authority, organization, agency or body.

12.3 “Code” means the Internal Revenue Code of 1986, as it may be amended from time to time.
12.4 “Disability” or “Disabled” means a physical or mental condition in which the Participant is:

i.

ii.

iii.

iv.

unable to engage in any substantial gainful activity by reason of any medically determinable physical or
mental impairment that can be expected to result in death or can be expected to last for a continuous period
of not less than twelve (12) months;

by reason of any medically determinable physical or mental impairment which can be expected to result in
death or can be expected to last for a continuous period of not less than twelve (12) months, receiving
income replacement benefits for a period of not less than three (3) months under the Employer’s accident
and health plan;

determined to be totally disabled by the Social Security Administration; or

disabled pursuant to an Employer-sponsored disability insurance arrangement provided that the definition of
disability applied under such disability insurance program complies with the foregoing definition of
Disability.

12.5 “Related Company” means the ALLETE, Inc. and all persons with whom the ALLETE, Inc. would be considered a

single employer under Code section 414(b) (employees of controlled group of corporations), and all persons with whom such
person would be considered a single employer under Code section 414(c) (employees of partnerships, proprietorships, etc., under
common control); provided that in applying Code sections 1563(a)(1), (2), and (3) for purposes of determining a controlled group
of corporations under Code section 414(b), the language “at least 50 percent” is used instead of “at least 80 percent” each place it
appears in Code sections 1563(a)(1), (2), and (3), and in applying Treasury Regulations section 1.414(c)-2 for purposes of
determining trades or businesses (whether or not incorporated) that are under common control for purposes of Code section
414(c), “at least 50 percent” is used instead of “at least 80 percent” each place it appears in Treasury Regulations section
1.414(c)-2.

12.6 “Retirement” or “Retires” means Separation from Service, for reasons other than death or Disability, on or after

attaining normal retirement age or early retirement age as defined in the most applicable qualified retirement plan sponsored by
the Related Company that employed the Participant immediately preceding the Separation from Service, without regard to
whether the Participant is a participant in such plan, or if the employer Related Company does not sponsor such retirement plan,
on or after attaining Normal Retirement Age or Early Retirement Age as defined in the ALLETE and Affiliated Companies
Retirement Plan A, without regard to whether the Participant is a participant under the ALLETE and Affiliated Companies
Retirement Plan A.

12.7 “Section 409A” means Section 409A of the Code and Treasury Regulations section 1.409A-1 et seq., as they both

may be amended from time to time, or other guidance issued by the Treasury Department and Internal Revenue Service
thereunder.

7

Exhibit 10(i)17

12.8 “Separation from Service” means that the Participant terminates employment within the meaning of Treasury

Regulations section 1.409A-1(h) and other applicable guidance with all Related Companies. Whether a termination of
employment has occurred is determined under the facts and circumstances, and a termination of employment shall occur if all
Related Companies and the Participant reasonably anticipate that no further services shall be performed after a certain date or that
the level of bona fide services the Participant shall perform after such date (as an employee or an independent contractor) shall
permanently decrease to no more than 20 percent of the average level of bona fide services performed (whether as an employee
or an independent contractor) over the immediately preceding 36-month period (or the full period of services to the Related
Companies if the Participant has been providing services to the Related Companies less than 36 months). A Participant shall not
be considered to separate from service during a bona fide leave of absence for less than six (6) months or longer if the Participant
retains a right to reemployment with any Related Company by contract or statute. With respect to disability leave, a Participant
shall not be considered to separate from service for 29 months unless the Participant otherwise terminates employment or is
terminated by all Related Companies.

12.9 “Specified Employee” means an Participant who is subject to the six-month delay rule described in Code section
409A(2)(B)(i), determined in accordance with guidelines adopted by the Board from time to time as permitted by Section 409A
of the Code and Treasury Regulations section 1.409A-1 et seq., as they both may be amended from time to time, and other
guidance issued by the Treasury Department and Internal Revenue Service thereunder.

ANNEX A
TO
ALLETE
EXECUTIVE LONG-TERM INCENTIVE COMPENSATION PLAN
PERFORMANCE SHARE GRANT

The Performance Share Grant to which this is annexed is subject to the following additional terms and conditions:

1. Dividend Equivalents. You will receive Dividend Equivalents with respect to Performance Shares that are earned and payable.
Dividend Equivalents are calculated and credited to you after the Performance Period has ended. The Dividend Equivalents will
be in the form of additional Performance Shares, which will be added to the number of Performance Shares earned, and will
equal the number of Shares (including fractional Shares) that could have been purchased on applicable dividend payment dates,
based on the closing ALLETE common stock price as reported in the consolidated transaction reporting system on that date, with
cash dividends that would have been paid on underlying Performance Shares, if such Performance Shares were Shares. Dividend
Equivalents will only become payable if and to the extent the underlying Performance Shares are earned and become payable.

2. Satisfaction of Goals. Performance Shares remain unearned unless and until Performance Goals are achieved. After the
Performance Period has ended, the Executive Compensation Committee (the “Committee”) will determine the extent to which
the Performance Goals have been met. You will not earn any Performance Shares if the threshold performance level has not been
met. Subject to the provisions of Section 4 below and to provisions in the Plan for change in control, Performance Shares will be
earned as follows: If the threshold level has been met, you will have earned 50% of the Performance Shares (as increased by the
Dividend Equivalents). If the target level has been met, you will have earned 100% of the Performance Shares (as increased by
the Dividend Equivalents). If the superior level has been met, you will have earned 200% of the Performance Shares (as
increased by the Dividend Equivalents). Straight line interpolation will be used to determine earned awards based on achievement
of goals between the threshold, target and superior levels.

3. Payment. Subject to the provisions of Section 4 below and to provisions in the Plan for Change in Control, Performance Shares
(as increased by the Dividend Equivalents) shall be paid in full after the Committee has determined the extent to which
Performance Goals have been met and within two and one half months after the end of the Performance Period. Payment shall be
made, after withholding Performance Shares in an amount equal in value to the minimum amount of tax required to be withheld
by law, by depositing ALLETE common stock into your Invest Direct account. Performance Share awards shall not vest until
paid.

4. Payment Upon Death, Retirement or Disability; Forfeiture of Unvested Performance Shares Upon Demotion, Unsatisfactory
Job Performance, Default on Certain Agreements or Other Separation from Service.

4.1 If during a Performance Period you (i) Retire, (ii) die while employed by a Related Company, or (iii) become

Disabled, you (or your beneficiary or estate) will receive a payment of any Performance Shares (as increased by the Dividend
Equivalents) after the end of the Performance Period in accordance with Section 3 above. The payment shall be prorated based
upon the number of whole calendar months within the Performance Period which had elapsed as of the date of death, Retirement
or Disability in relation to the number of calendar months in the full Performance Period. A whole month is counted in the
calculation if you were in the position as of the 15  of the month.

th

Exhibit 10(i)15

4.2 If after the end of a Performance Period, but before any or all Performance Shares have been paid, you Retire,

die or become Disabled, you (or your beneficiary or estate) will be entitled to full payout of all earned Performance Shares (as
increased by the Dividend Equivalents) in accordance with Section 3 above.

4.3 If, prior to payment of all Performance Shares, you are demoted, you default on any written agreement with a

Related Company related to a restrictive employment covenant (such as confidentiality, non-disclosure, non-competition, non-
solicitation, or the like) or ALLETE determines, in its sole discretion, that your job performance is unsatisfactory, ALLETE
reserves the right to cancel or amend your grant relating to any unpaid Performance Shares, with the result that some portion or
all of your unpaid Performance Shares (and related Dividend Equivalents) will be forfeited.

4.4 If you have a Separation from Service for any reason other than those specified in subsection 4.1 above, all

Performance Shares (and related Dividend Equivalents), to the extent not yet paid, shall be forfeited on the date of such
Separation from Service, except as otherwise provided by the Committee.

5. Compensation Recovery Policy. The Grant is subject to the terms of any compensation recovery policy or policies established
by ALLETE as may be amended from time to time (“Compensation Recovery Policy”). ALLETE hereby incorporates into the
Grant the terms of the Compensation Recovery Policy.

6. Section 409A Compliance. This Grant is intended to comply with Section 409A of the Code (“Section 409A”) or an exemption
thereunder, and, accordingly, to the maximum extent permitted, the Plan and the Grant shall be interpreted and administered in
compliance therewith. Notwithstanding any other provision of the Grant, payments provided pursuant to the Grant may only be
made upon an event and in a manner that complies with Section 409A or an applicable exemption. Any payments pursuant to the
Grant that may be excluded from Section 409A as a short-term deferral shall be excluded from Section 409A to the maximum
extent possible. To the extent that any provision of the Grant would cause a conflict with the requirements of Section 409A or
would cause the administration of the Grant to fail to satisfy Section 409A, such provision shall be deemed null and void to the
extent permitted by applicable law. Nothing herein shall be construed as a guarantee of any particular tax treatment. ALLETE
makes no representation that the Grant complies with Section 409A and in no event shall ALLETE be liable for the payment of
any taxes and penalties that you may incur under Section 409A.

7. Claims Procedure and Arbitration. The Grant is subject to the following claims procedures:

7.1 Mandatory Claims Procedures. If you or any person acting on your behalf (the “Claimant”) has any claim or dispute
related in any way to the Grant or to the Plan, the Claimant must follow these claims procedures. All claims must be brought no
later than one year following the date on which the claim first arose and any claim not submitted within such time limit will be
waived.

7.2 Claim Submission. Any claim must be made in writing to the Claims Administrator. The Claims Administrator, or its

delegate, shall notify the Claimant of the resolution of the claim within 90 days after receipt of the claim; provided, however, if
the Claims Administrator determines that an extension is necessary, the 90-day period shall be extended to up to 180 days upon
notice to that effect to the Claimant.

7.3 Notice of Denial. If a claim is wholly or partially denied, the denial notice shall contain (i) the reason or reasons for

denial of the claim, and (ii) references to the pertinent Plan provisions upon which the denial is based. Unless the claim is
submitted for arbitration as provided below and in the

2

Exhibit 10(i)15

Plan, the Claims Administrator’s decision or action shall be final, conclusive and binding on all persons having any interest in the
Plan.

7.4 Arbitration. If, after exhausting the procedures set forth above, a Claimant wishes to pursue legal action, any action by

the Claimant with respect to a claim, must be resolved by arbitration in the manner described herein.

Rules of the American Arbitration Association.

c. Venue. The arbitration shall be conducted in Minneapolis, Minnesota.

Claim relating to your Grant, agree to waive any right to sue in court or to pursue any other legal right or remedy that
might otherwise be available in connection with the resolution of the Claim.

the parties.

with any other person or entity. To the fullest extent permitted by law, whether in court or in arbitration, by participating
in the Plan, you waive any right to commence, be a party to in any way, or be an actual or putative class member of any
class, collective, or representative action arising out of or relating to any claim, and you agree that any claim may only be
initiated or maintained and decided on an individual basis.

g. Standard of Review. Any decision of an arbitrator on a claim shall be limited to determining whether the Claims

Administrator’s decision or action was arbitrary or capricious or was unlawful. The arbitrator shall adhere to and apply
the deferential standard of review set out in Conkright v. Frommert, 130 S. Ct. 1640 (2010), Metropolitan Life Insurance
Co. v. Glenn, 554 U.S. 105 (2008), and Firestone Tire and Rubber Company v. Bruch, 489 U.S. 101 (1989), and shall
accord due deference to the determinations, interpretations, and construction of the Plan document by the Claims
Administrator.

[Eligible Executive Employees]
ANNEX B
TO
ALLETE
Executive Long Term Incentive Compensation Plan

                    Performance Share Grant

Financial Measure:
Fifty percent (50%) of the total performance share opportunity is based on Total Shareholder Return (TSR) computed over the
three-year performance period January 1, 2022 to December 31, 2024.

Fifty percent (50%) of the total performance share opportunity is based on the Company’s Compound Annual Growth Rate
(CAGR) computed over the three-year performance period January 1, 2022 to December 31, 2024.

Performance Share Award (TSR metric):
Achievement will be weighted on TSR performance in accordance with ALLETE’s TSR ranking as follows: at the 85th
percentile or higher among the peer group (superior performance), 200% of the weighted Performance Share Grant will be
earned. If ALLETE’s TSR ranking is at the 50  percentile among the peer group (target performance), 100% of the weighted
Performance Share Grant will be earned. If ALLETE’s TSR ranking is at the 30  percentile (threshold performance), 50% of the
weighted Performance Share Grant will be earned. If TSR ranking is below threshold, no weighted Performance Shares will be
earned. Straight-line interpolation will be used to determine earned awards based on the TSR ranking between threshold, target
and superior.

th

Peer Group:
The integrated utility companies comprising Edison Electric Institute (EEI) Stock Index as of December 31, 2024 that have been
in the EEI Stock Index for at least three years as of December 31, 2024 will constitute the peer group used to determine actual
payout results. The table below lists the EEI Stock Index as of December 31, 2021, based on published information available as
of that date:

Alliant Energy Corporation
Ameren Corporation
American Electric Power Company
Avangrid, Inc.
Avista Corporation
Black Hills Corporation
CenterPoint Energy, Inc.
CMS Energy Corporation
Consolidated Edison, Inc.
Dominion Energy, Inc.

Any Company that is no longer included in the EEI Stock Index as of December 31, 2024 due to corporate restructuring during
the performance period (e.g., mergers, acquisitions, divestitures, spin-offs, etc.) will be excluded from the results calculation
entirely. If a corporate restructuring during the performance period results in a company remaining in the EEI Stock Index
following the transaction (and thus not

Exhibit 10(i)18

being excluded from the results calculation entirely), from the point of the transaction forward, the results calculation will track
only the entity that remains in the EEI Stock Index and ignore other entities, regardless of whether such other entities are publicly
traded.

Performance Share Award (CAGR metric):

CAGR will be calculated by using the baseline pro forma Earnings per Share (EPS) for the year ending December 31 of the year
prior to the beginning of the three-year performance period and the pro forma EPS at the end of the three-year performance
period. Achievement will be weighted on CAGR performance in accordance with the following table:

Compound Annual Growth Rate
Superior [ ]%
Target [ ]%
Threshold [ ]%

Payout Percentage (% of Target Award)
200%
100%
50%

If CAGR percentage result is below threshold, no weighted Performance Shares will be earned. Straight-line interpolation will be
used to determine earned awards based on the CAGR percentage result between threshold, target and superior.

NEWS

ALLETE, Inc. reports 2021 earnings of $3.23 per share; initiates 2022 earnings guidance range of $3.60
to 3.90 per share

DULUTH, Minn. - ALLETE, Inc. (NYSE: ALE) today reported 2021 earnings of $3.23 per share on net income of $169.2 million and
operating revenue of $1.4 billion. Reported results from 2020 were $3.35 per share on net income of $174.2 million and operating revenue of
$1.2 billion.

Earnings in 2021 reflect an approximately 16 cent gain recorded in the fourth quarter of 2021 for the sale of a portion of the Nemadji Trail
Energy Center by South Shore Energy, ALLETE’s non-rate regulated, Wisconsin subsidiary. This positive impact was partially offset by a 10
cent per share, negative impact related to ALLETE Clean Energy’s Diamond Spring wind energy facility due to the February extreme winter
storm event. Additionally, net income in 2021 included a 7 cent per share charge resulting from the Minnesota Public Utilities Commission’s
decision to order refunds in Minnesota Power’s fuel adjustment clause filing covering the period July 2018 through December 2019.
“I am pleased with the Company’s 2021 financial results and strategic clean energy positioning as we launch 2022 from a position of
strength,” said ALLETE Chair, President and CEO Bethany Owen, “ALLETE’s Sustainability in Action strategy will continue to capitalize
on demand for clean energy, providing value to our customers, our communities and our investors, as well as opportunities for our
employees.”

ALLETE’s Regulated Operations segment, which includes Minnesota Power, Superior Water, Light and Power and the Company’s
investment in the American Transmission Co., recorded net income of $129.1 million, compared to $136.3 million in 2020. Earnings reflect
lower net income at Minnesota Power primarily due to: lower margins from the expiration of a power sales contract in 2020; higher operating
and maintenance, property tax and depreciation expenses; and the reserve for refunds in Minnesota Power’s fuel adjustment clause filing.
These negative impacts were partially offset by increased earnings related to the Great Northern Transmission Line; and higher kilowatt-hour
sales to retail and municipal customers. Net income in 2020 also included the rate case resolution impact of $8.3 million after-tax.

ALLETE Clean Energy recorded 2021 net income of $26.3 million compared to $29.9 million in 2020. Net income in 2021 included the
impact related to ALLETE Clean Energy’s Diamond Spring wind energy facility due to an extreme winter storm event in the southwest
United States in February 2021 as well as lower wind resources at other wind energy facilities. These negative impacts were partially offset
by expense management efforts.

Corporate and Other businesses, which include BNI Energy and ALLETE Properties, recorded net income of $13.8 million in 2021
compared to net income of $8 million in 2020. Net income in 2021 included South Shore Energy’s sale of a portion of its interest in NTEC to
Basin Electric Cooperative which resulted in the recognition of an approximately $8.5 million after-tax gain related to prior development
costs and risks incurred, higher earnings from our investment in Nobles 2 which commenced operations in December 2020 and higher net
income from land sales at ALLETE Properties. These increases were partially offset by higher expenses.

“I am pleased with our financial performance and accomplishments in 2021, wrapping up the year with a strong fourth quarter; our
businesses are well positioned as we move into 2022 and beyond,” said ALLETE Senior Vice President and Chief Financial Officer Steve
Morris, “We believe our unique mix of businesses will continue to deliver a strong value proposition to shareholders for years to come.”

Details of the Company’s 2022 earnings guidance were filed as part of today’s Form 8-K filing.

results and 2022 earnings guidance. To participate in the call, analysts are asked to dial 877-303-5852, pass code 1993529, ten minutes prior
to the start time and refer to the “ALLETE’s Conference Call Announcing 2021 Financial Results.” All interested parties may listen to the

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. Actual results may differ materially from those projected in the forward-looking
statements. These forward-looking statements involve risks and uncertainties and investors are directed to the risks discussed in
documents filed by ALLETE with the Securities and Exchange Commission.

ALLETE's press releases and other communications may include certain non-Generally Accepted Accounting Principles (GAAP)
financial measures. A "non-GAAP financial measure" is defined as a numerical measure of a company's financial performance,
financial position or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly
comparable measure calculated and presented in accordance with GAAP in the company's financial statements.

Non-GAAP financial measures utilized by the Company include presentations of earnings (loss) per share. ALLETE's
management believes that these non-GAAP financial measures provide useful information to investors by removing the effect of
variances in GAAP reported results of operations that are not indicative of changes in the fundamental earnings power of the
Company's operations. Management believes that the presentation of the non-GAAP financial measures is appropriate and
enables investors and analysts to more accurately compare the company's ongoing financial performance over the periods
presented.
