Risk Factors
Investing in our common stock involves certain risks. In considering whether to purchase our common stock offered by this prospectus supplement and the accompanying prospectus, you should carefully consider the risks described below, as well as the information included or incorporated by reference in this prospectus supplement and the accompanying prospectus. In particular, you should carefully consider the information under the heading “Forward-Looking Statements” above and under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2021, which is incorporated by reference herein.
Entity-wide Risks
We supplement the information under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2021, which is incorporated by reference herein, with the following:
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 included in our Annual Report on Form 10-K for the year ended December 31, 2021. 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. For example, the federal renewable energy production tax credit expired as of December 31, 2021, although we may still receive the benefit of the production tax credit from previously completed wind energy facilities as well as for certain facilities that were under construction as of December 31, 2021. In November 2021, the U.S. House of Representatives passed the Build Back Better legislation, which contained extensive renewable energy incentives aimed at combating the climate crisis, including an extension to the production tax credit. However, the U.S. Senate has yet to approve such legislation, and there is no assurance that the production tax credit will be renewed. Because our tax equity financing transactions depend on the availability of credits such as the production tax credit, the expiration of such credits may cause an increase in our cost of financing wind energy projects and may reduce our ability to construct a wind energy facility on favorable terms, or at all.
Risks related to an investment in our common stock
The price of our common stock may fluctuate significantly, and this may make it difficult for you to resell shares of our common stock owned by you at times or at prices you find attractive.
The trading price of our common stock may fluctuate widely as a result of a number of factors, many of which are outside our control.
In recent years, the stock market has experienced significant price and volume fluctuations. This volatility frequently has occurred without regard to the operating performance of the affected companies. Hence, the price of our common stock could fluctuate based upon factors that have little or nothing to do with us, and these fluctuations could materially reduce our share price.
A significant decline in our stock price could result in substantial losses for individual shareholders and could lead to costly and disruptive securities litigation.
 
S-5

 
There may be future sales or other dilution of our equity, which may materially adversely affect the market price for shares of our common stock.
We are generally not restricted from issuing additional shares of our common stock, including any securities that are convertible into or exchangeable for, or that represent the right to receive, shares of our common stock or any substantially similar securities. The market price for shares of our common stock could materially decline as a result of sales of shares of our common stock or similar securities in the market made after such offering or the perception that such sales could occur.
All of our debt obligations have priority over shares of our common stock, which would subordinate your rights to payment as a holder of our common stock in the event of a liquidation, dissolution or winding up.
In any liquidation, dissolution or winding up of ALLETE, shares of our common stock would rank below all debt claims against us. As a result, holders of shares of our common stock would not be entitled to receive any payment or other distribution of assets upon the liquidation, dissolution or winding up of ALLETE until after our obligations to our debt holders have been satisfied.
You may not receive dividends on our common stock.
Holders of our common stock are only entitled to receive such dividends as our board of directors may declare out of funds legally available for such payments. Although we have in the past declared cash dividends on our common stock, we are not required to do so and may reduce or eliminate our common stock dividend in the future. This could adversely affect the market price of our common stock.

U.S. Federal Income Tax Consequences for Non-U.S. Holders
The following describes the material U.S. federal income tax consequences to “non-U.S. holders” ​(as defined below) of the ownership and disposition of our common stock sold pursuant to this offering. This discussion deals only with our common stock purchased in this offering that is held as a “capital asset” within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended, or the “Code” ​(generally, property held for investment), by a non-U.S. holder. For purposes of this discussion, the term “non-U.S. holder” means a beneficial owner of our common stock that is not any of the following:

an individual who is a citizen or resident of the United States;

a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any state thereof or the District of Columbia;

an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

a trust if (a) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) the trust has in effect a valid election to be treated as a domestic trust for U.S. federal income tax purposes.
This discussion does not address all U.S. federal income tax consequences relevant to a non-U.S. holder’s individual circumstances. Specifically, it does not address consequences relevant to U.S. expatriates and certain former citizens or long-term residents of the United States and partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes.
This discussion is based on the U.S. federal income tax laws, regulations, rulings and decisions in effect as of the date hereof, which are subject to change or differing interpretations, possibly on a retroactive basis. No ruling has been or will be sought from the U.S. Internal Revenue Service, or “IRS,” with respect to the matters discussed below, and there can be no assurance that the IRS would not take a contrary position regarding the tax consequences of the ownership or disposition of our common stock, or that such contrary position would not be sustained by a court. Moreover, this discussion does not address the U.S. state and local, U.S. federal gift, or non-U.S. tax considerations relating to the ownership and disposition of our common stock.
If a partnership (or other entity treated as a partnership for U.S. federal income tax purposes) holds our common stock, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships holding our common stock and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.
This discussion is for information purposes only and is not intended as tax advice. Investors should consult their tax advisors with respect to the application of the U.S. federal income tax laws to their particular situations, as well as any tax consequences of the ownership and disposition of our common stock arising under the U.S. federal estate or gift tax laws, the laws of any state, local or non-U.S. taxing jurisdiction or any applicable income tax treaty.
Distributions
A distribution on our common stock will constitute a dividend for U.S. federal income tax purposes to the extent of our current or accumulated earnings and profits as determined under the Code. Any distribution not treated as a dividend for U.S. federal income tax purposes will constitute a return of capital and first be applied against and reduce a non-U.S. holder’s adjusted tax basis in its common stock, but not below zero. Any excess will be treated as capital gain and will be treated as described below in the section “Sale or Other Taxable Disposition of Our Common Stock.”
Subject to the discussions below on backup withholding, dividends paid to a non-U.S. holder of our common stock that are not effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount

of the dividends (or a lower rate specified under an applicable income tax treaty). In order to receive a reduced treaty rate, a non-U.S. holder must provide to the applicable withholding agent an IRS Form W-8BEN (or applicable substitute or successor form) properly certifying eligibility for the reduced rate. Non-U.S. holders that do not timely provide the applicable withholding agent with the required certification, but that qualify for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. holders should consult their tax advisors regarding their entitlement to benefits under an applicable income tax treaty.
Subject to the discussions below on backup withholding, dividends that are effectively connected with a non-U.S. holder’s conduct of a trade or business in the United States and, if an income tax treaty so requires, are attributable to a permanent establishment maintained by the non-U.S. holder in the United States, are taxed on a net-income basis at the regular rates and in the manner applicable to U.S. persons. In that case, the applicable withholding agent will not have to withhold U.S. federal withholding tax if the non-U.S. holder complies with applicable certification and disclosure requirements (which generally are met by providing an IRS Form W-8ECI). In addition, a “branch profits tax” may be imposed at a 30% rate (or a lower rate specified under an applicable income tax treaty) on a foreign corporation’s effectively connected earnings and profits for the taxable year, as adjusted for certain items.
Sale or other taxable disposition of our common stock
Subject to the discussions below on backup withholding and foreign accounts, a non-U.S. holder will not be subject to U.S. federal income or withholding tax on any gain recognized upon the sale or other disposition of our common stock unless:

the gain is effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the non-U.S. holder maintains a permanent establishment in the United States to which such gain is attributable);

the non-U.S. holder is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met; or

our common stock constitutes a U.S. real property interest by reason of our status as a U.S. real property holding corporation, or a “USRPHC,” for U.S. federal income tax purposes.
Gain described in the first bullet point above will generally be subject to U.S. federal income tax on a net-income basis at the regular graduated U.S. federal income tax rates. A non-U.S. holder that is a foreign corporation also may be subject to a branch profits tax at a rate of 30% (or a lower rate specified under an applicable income tax treaty) of its effectively connected earnings and profits for the taxable year, as adjusted for certain items.
A non-U.S. holder described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or a lower rate specified under an applicable income tax treaty) on any gain derived from the disposition (even though the individual is not considered a resident of the United States), which may be offset by certain U.S.-source capital losses of the non-U.S. holder provided the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses.
With respect to the third bullet point above, we believe that we have not been and currently are not a USRPHC, and we do not expect to become one in the future based on anticipated business operations. However, because the determination of whether we are a USRPHC depends on the fair market value of our U.S. real property relative to the fair market value of our worldwide real property interests and other business assets, there can be no assurance that we are not currently or will not in the future become a USRPHC. Even if we are or become a USRPHC, so long as our common stock is regularly traded on an established securities market, a non-U.S. holder will be subject to U.S. federal income tax on any gain not otherwise taxable only if such non-U.S. holder actually or constructively owned more than 5% of our outstanding common stock at some time during a specified period. The New York Stock Exchange, on which our common stock is currently traded, is considered an established securities market for these purposes. Non-U.S. holders should consult their tax advisors about the consequences that could result if we are, or become, a USRPHC.
 
S-11

 
Non-U.S. holders should also consult their tax advisors regarding potentially applicable income tax treaties that may provide for different rules.
Information reporting and backup withholding
Payments of dividends on our common stock will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know that the beneficial owner is a U.S. person and such beneficial owner certifies its non-U.S. status by providing a valid IRS Form W-8BEN or W-8ECI or other applicable certification. However, information returns will be filed with the IRS in connection with any dividends on our common stock paid to the non-U.S. holder, regardless of whether any tax was actually withheld. Copies of these information returns may also be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which the non-U.S. holder resides or is established.
Information reporting and, depending on the circumstances, backup withholding will apply to the proceeds of a sale of our common stock within the United States or conducted through certain U.S.-related financial intermediaries, unless the non-U.S. holder certifies under penalty of perjury that it is not a U.S. person (and the payor does not have actual knowledge or reason to know that the beneficial owner is a U.S. person) or the non-U.S. holder otherwise establishes an exemption.
Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a credit against a non-U.S. holder’s U.S. federal income tax liability, and may entitle such non-U.S. holder to a refund, provided the required information is timely furnished to the IRS.
Additional withholding tax on payments made to foreign accounts
Withholding tax may be imposed under legislation commonly referred to as the Foreign Account Tax Compliance Act, or “FATCA,” on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends on, or gross proceeds from the sale or other disposition of, our common stock paid to a “foreign financial institution” or a “non-financial foreign entity” ​(each as defined in the Code), unless (a) the foreign financial institution undertakes certain diligence and reporting obligations, (b) the non-financial foreign entity either certifies it does not have any “substantial United States owners” ​(as defined in the Code) or furnishes identifying information regarding each substantial United States owner or (c) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (a) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States owned foreign entities” ​(each as defined in the Code), annually report certain information about such accounts and withhold 30% on payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.
Under the applicable Treasury regulations, withholding under FATCA generally applies to payments of dividends on our common stock. Pursuant to proposed regulations, the Treasury Department has indicated its intent to eliminate the requirements under FATCA of withholding on gross proceeds from the sale or other disposition of certain financial instruments (which would include our common stock). The Treasury Department has indicated that taxpayers may rely on these proposed regulations pending their finalization. We will not be obligated to make any “gross up” or additional payments in respect of amounts withheld on shares of our common stock if we determine that we must so withhold in order to comply with FATCA in respect of the amounts described above. Prospective investors should consult their own tax advisors regarding FATCA and whether it may be relevant to the ownership and disposition of shares of our common stock.

Price Stabilization and Short Positions
In connection with this offering, the underwriters may engage in stabilizing transactions, which involves making bids for, purchasing and selling shares of our common stock in the open market for the purpose of preventing or retarding a decline in the market price of our common stock while this offering is in progress. These stabilizing transactions may include making short sales of our common stock, which involves the sale by the underwriters of a greater number of shares of our common stock than they are required to purchase in this offering, and purchasing shares of our common stock on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through the option. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares in the open market to cover the position.
The underwriters have advised us that, pursuant to Regulation M of the Securities Act, they may also engage in other activities that stabilize, maintain or otherwise affect the price of our common stock, including the imposition of penalty bids. This means that if the representatives of the underwriters purchase our common stock in the open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.
These activities may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock, and, as a result, the price of our
 
S-15

 
common stock may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on the New York Stock Exchange, in the over-the-counter market or otherwise.
Sales outside the United States

The securities offered by this prospectus supplement and the accompanying prospectus may not be offered or sold, directly or indirectly, nor may this prospectus supplement and the accompanying prospectus or any other offering material or advertisements in connection with the offer and sale of any such securities be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction.

On March 27, 2019, ALLETE announced that its subsidiary, ALLETE Enterprises, Inc., completed the previously announced sale of the common stock of its subsidiary, Global Water Services Holding Company, Inc., the parent company of U.S. Water Services, Inc., to a subsidiary of Kurita Water Industries Ltd. ALLETE received approximately $265 million in cash at closing, net of transaction costs and cash retained.
Corporate and Other is comprised of BNI Energy, ALLETE’s coal mining operations in North Dakota, ALLETE’s investment in Nobles 2 Power Partners, LLC, ALLETE Properties LLC and its subsidiaries, ALLETE’s 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.
USE OF PROCEEDS
Unless otherwise stated in a prospectus supplement, ALLETE will add the net proceeds from the sale of the securities to its general funds. ALLETE uses its general funds for corporate purposes, including, without limitation, capital investments in its existing business, acquisitions made by or on behalf of it or its subsidiaries, to repay short-term borrowings or to repay, redeem or repurchase outstanding debt. ALLETE may temporarily invest any proceeds that it does not immediately need.
DESCRIPTION OF COMMON STOCK
General.   The following statements describing ALLETE’s common stock are not intended to be a complete description. For additional information, please see ALLETE’s Articles of Incorporation and Bylaws. Each of these documents has been previously filed with the SEC and they are exhibits to the registration statement filed with the SEC of which this prospectus is a part. Reference is also made to the laws of the State of Minnesota.
ALLETE has the following capital stock authorized by its Articles of Incorporation: 80,000,000 shares of common stock, without par value, and 3,616,000 shares of preferred stock. As of June 30, 2019, 51,655,541 shares of common stock were issued and outstanding and no shares of preferred stock were issued and outstanding.
Dividend Rights.   ALLETE’s common stock is entitled to dividends only after ALLETE has provided for dividends and any sinking fund requirements on any issued and outstanding preferred stock. ALLETE’s Articles of Incorporation contain provisions which would restrict net income available for the payment of cash dividends on outstanding common stock in the event that shares of ALLETE’s preferred stock were outstanding and certain common stock equity capitalization ratios were not met.
Voting Rights (Non-Cumulative Voting).   Holders of ALLETE’s common stock are entitled to receive notice of and to vote at any meeting of shareholders. Each share of ALLETE’s common stock, as well as each share of any of ALLETE’s issued and outstanding preferred stock, is entitled to one vote. Holders of ALLETE’s common stock do not have cumulative voting rights. Each director is elected by the vote of a majority of the votes cast with respect to the director at a meeting of shareholders called for such purpose at which a quorum is present. At any such meeting for which the number of nominees (other than nominees withdrawn on or before the sixtieth (60th) day before the first anniversary of the preceding year’s annual shareholder meeting) exceeds the number of directors to be elected, directors are elected by a plurality of the votes present and entitled to vote on the election of directors. In addition, whenever dividends on any of ALLETE’s preferred stock are in default in the amount of four full quarterly payments or more, and until all the dividends in default are paid, the holders of ALLETE’s preferred stock are entitled, as one class, to elect a majority of the directors. ALLETE’s common stock, as one class, would then elect the minority.
The Articles of Incorporation include detailed procedures and other provisions relating to these rights and their termination, including:

quorums;

terms of directors elected;

vacancies;
 
4

 

class voting;

meetings; and

adjournments.
The Articles of Incorporation contain provisions that make it difficult to obtain control of ALLETE through transactions not having the approval of the board of directors of ALLETE. These provisions include:

a provision requiring the affirmative vote of 75 percent of the outstanding shares of all classes of ALLETE’s capital stock, present and entitled to vote, in order to authorize certain mergers or consolidations, or sales or leases of a significant amount of assets, of ALLETE, and other significant transactions that may have an effect on the control of ALLETE. Any of those transactions are required to meet certain “fair price” and procedural requirements. Neither a 75 percent shareholder vote nor a “fair price” is required for any of those transactions that have been approved by a majority of the “Disinterested Directors,” as that term is defined in the Articles of Incorporation;

a provision permitting a majority of the Disinterested Directors to determine whether the above requirements have been satisfied; and

a provision providing that some parts of the Articles of Incorporation cannot be altered unless approved by 75 percent of the outstanding shares of all classes of ALLETE’s capital stock, present and entitled to vote, unless the alteration is recommended to the shareholders by a majority of the Disinterested Directors. The parts of the Articles of Incorporation that cannot be altered except as stated above include some parts relating to:

mergers or consolidations, or sales or leases of a significant amount of assets, of ALLETE, and other significant transactions that may have an effect on the control of ALLETE; and

the number, election, terms of office and removal of directors of ALLETE and the way in which vacancies on the board of directors are filled.
Liquidation Rights.   After ALLETE has satisfied creditors and the preferential liquidation rights of any of its outstanding preferred stock, the holders of its common stock are entitled to share ratably in the distribution of all remaining assets.
Miscellaneous.   Holders of ALLETE’s common stock have no preemptive or conversion rights. ALLETE’s common stock is listed on the New York Stock Exchange. The transfer agent and registrar for ALLETE’s common stock is EQ Shareowner Services.
DESCRIPTION OF FIRST MORTGAGE BONDS
General.   The following description sets forth certain general terms and provisions of ALLETE’s first mortgage bonds that ALLETE may offer by this prospectus. ALLETE will describe the particular terms of the first mortgage bonds, and provisions that vary from those described below, in one or more prospectus supplements.
ALLETE may issue the first mortgage bonds from time to time in one or more series. ALLETE will issue the first mortgage bonds under its Mortgage and Deed of Trust, dated as of September 1, 1945, with Irving Trust Company (now The Bank of New York Mellon), as corporate mortgage trustee, and Richard H. West (Andres Serrano, successor), as individual mortgage trustee (together, the “mortgage trustees”), which has been amended and supplemented in the past, may be supplemented prior to the issuance of these first mortgage bonds and which will be supplemented again by one or more supplemental indentures relating to these first mortgage bonds. The Mortgage and Deed of Trust, as so amended and supplemented, is referred to in this prospectus as the “mortgage.”
This section briefly summarizes some of the terms of the first mortgage bonds and some of the provisions of the mortgage and uses some terms that are not defined in this prospectus but that are defined in the mortgage. This summary is not complete. You should read this summary together with the mortgage and the supplemental indenture establishing the first mortgage bonds for a complete understanding of all the
 
5

 
provisions. References to certain sections of the mortgage and particular supplemental indentures are included in parentheses. The mortgage and the form of supplemental indenture have been previously filed with the SEC, and are exhibits to the registration statement filed with the SEC of which this prospectus is a part. In addition, the mortgage is qualified as an indenture under the Trust Indenture Act of 1939 and is therefore subject to the provisions of the Trust Indenture Act of 1939. You should read the Trust Indenture Act of 1939 for a complete understanding of its provisions. All first mortgage bonds issued or to be issued under the mortgage, including the first mortgage bonds offered by this prospectus, are referred to herein as “first mortgage bonds.”
All first mortgage bonds of one series need not be issued at the same time, and a series may be re-opened for issuances of additional first mortgage bonds of such particular series. This means that ALLETE may from time to time, without notice to, or the consent of the existing holders of previously-issued first mortgage bonds of a particular series, create and issue additional first mortgage bonds of such series. Such additional first mortgage bonds will have the same terms as the first mortgage bonds of such series in all respects except for the issue date and, if applicable, the initial interest payment date, so that the additional first mortgage bonds may be consolidated and form a single series with the previously-issued first mortgage bonds of such series.
Reference is made to a prospectus supplement relating to each series of first mortgage bonds offered by this prospectus for the following specific terms of that series, among others:

the designation of the series of first mortgage bonds and aggregate principal amount of the first mortgage bonds,

the offering price of the series,

the place where the principal of and interest on the series will initially be payable, if other than at The Bank of New York Mellon in New York, New York,

the date or dates on which the series will mature,

the rate or rates at which the series will bear interest, or method for determining the interest rate(s),

the dates on which such interest will be payable,

the currency or currencies in which payment of the principal of and interest on the series may be made, if other than United States dollars,

whether all or a portion of the series will be in global form,

the redemption terms, and

any other terms or provisions relating to the series that are not inconsistent with the provisions of the mortgage.
The first mortgage bonds offered by this prospectus may be sold at a discount below their principal amount. Some of the important United States federal income tax considerations applicable to first mortgage bonds offered by this prospectus sold at a discount below their principal amount may be described in the applicable prospectus supplement. In addition, some of the important United States federal income tax or other considerations applicable to any first mortgage bonds offered by this prospectus which are denominated or payable in a currency or currency unit other than United States dollars may be described in the applicable prospectus supplement.
Except as may otherwise be described in a prospectus supplement, the covenants contained in the mortgage will not afford holders of the first mortgage bonds protection in the event of a highly-leveraged or similar transaction involving ALLETE or in the event of a change in control.
Reserved Amendment Rights.   ALLETE has reserved the right to amend the mortgage without the consent or other action of the holders of any of the first mortgage bonds created after January 31, 2010, to make the changes described below in this “Description of First Mortgage Bonds.” Holders of first mortgage bonds issued after January 31, 2010, including first mortgage bonds that ALLETE may offer by this prospectus, are deemed to have consented to these amendments. This section briefly summarizes the reserved amendment rights. This summary is not complete. You should read this summary together with

the thirty-first supplemental indenture, dated as of February 1, 2010, which has been previously filed with the SEC and is an exhibit to the registration statement filed with the SEC of which this prospectus is a part, together with the mortgage for a complete understanding of the reserved amendment rights.
Form and Exchanges.   The first mortgage bonds offered by this prospectus will be issued in fully registered form without coupons, unless otherwise stated in a prospectus supplement. Unless otherwise stated in a prospectus supplement, the first mortgage bonds will be issued in denominations of $1,000 and multiples thereof. The first mortgage bonds offered by this prospectus will be transferable and exchangeable without charge (except for stamp taxes, if any, or other governmental charges). ALLETE has initially designated The Bank of New York Mellon, in New York, New York, as the place where such transfers or exchanges may be made.
A holder of first mortgage bonds may exchange those first mortgage bonds for an equal aggregate principal amount of first mortgage bonds of the same series, having the same issue date and with identical terms and provisions, or may transfer those first mortgage bonds, in each case without cost to the holder, other than for applicable stamp taxes or other governmental charges, unless otherwise stated in the applicable prospectus supplement. ALLETE may issue all or some of the first mortgage bonds offered by this prospectus in “book-entry” form, which means that they will be represented by global notes, instead of certificates. The depository, or its custodian, will hold those global notes. Transfers of beneficial interests in those global notes will be accomplished by entries in the books of participants acting on behalf of beneficial owners. Any additional requirements as to the form and method of exchange of first mortgage bonds will be described in the applicable prospectus supplement.
Redemption and Purchase of First Mortgage Bonds.   The first mortgage bonds offered by this prospectus may be redeemable upon 30 days’ notice if the terms of the first mortgage bonds so provide. Reference is made to the applicable prospectus supplement for the prices and other terms and conditions, if any, for redemption of the first mortgage bonds offered by this prospectus. If the first mortgage bonds are redeemable, ALLETE may use certain deposited cash and/or proceeds of released property to effect the redemption.
If at the time a notice of redemption is given the redemption moneys are not on deposit with the corporate mortgage trustee, the redemption may be made subject to their receipt before the date fixed for redemption.
Cash deposited under any provisions of the mortgage (with certain exceptions) may generally be applied to the purchase of first mortgage bonds of any series. (See Mortgage, Article X.)
ALLETE or its affiliates, may at any time and from time to time, purchase all or some of the outstanding first mortgage bonds offered by this prospectus at any price or prices, whether by tender, in the open market or by private agreement or otherwise, subject to applicable law.
Sinking or Improvement Fund.   Unless otherwise stated in a prospectus supplement, the first mortgage bonds offered by this prospectus will not be entitled to the benefit of a sinking or improvement fund or other provision for amortization prior to maturity. None of the currently outstanding first mortgage bonds has sinking fund or improvement fund provisions.
Replacement Fund.   The first mortgage bonds offered by this prospectus are not entitled to the benefit of any replacement fund.
Special Provisions for Retirement of First Mortgage Bonds.   If, during any 12 month period, mortgaged property is disposed of by order of or to any governmental authority resulting in the receipt by ALLETE of $5 million or more as proceeds, ALLETE (subject to certain conditions) must apply such proceeds, less certain deductions, to the retirement of first mortgage bonds. If this occurs, ALLETE may redeem first mortgage bonds of any series that are redeemable for such reason at the redemption prices applicable to those first mortgage bonds. (See Mortgage, Section 64.) Reference is made to the applicable prospectus supplement for information concerning whether the first mortgage bonds offered by this prospectus are redeemable for this purpose and, if so, at what redemption prices.
Security.   The first mortgage bonds offered by this prospectus and any other first mortgage bonds now or hereafter issued under the mortgage will be secured by the mortgage, which constitutes a first lien

on all of the electric generating plants, electric transmission and distribution equipment and fixtures of ALLETE and substantially all other properties owned by ALLETE, other than property expressly excepted.
The lien of the mortgage is or may be subject to the following “excepted encumbrances”:

liens for taxes, assessments or governmental charges which are not delinquent or the validity of which is being contested at the time by ALLETE in good faith; and liens for workmen’s compensation awards and similar obligations which are not delinquent and undetermined liens or charges incidental to construction;

liens securing indebtedness, neither assumed nor guaranteed by ALLETE nor on which it customarily pays interest, existing on real property or rights in or relating to real property acquired by ALLETE for substation, transmission line, transportation line, distribution line or right of way purposes;

rights of any municipality or public authority to terminate any right, power, franchise, grant, license or permit or to purchase or recapture or to designate a purchaser of any of the property of ALLETE or to control or regulate any property of ALLETE, or to use such property in a manner which does not materially impair the use of such property for the purposes for which it is held by ALLETE;

rights of others to take or receive any part of the power, gas, oil or other minerals or timber generated, developed, produced, manufactured, pumped or stored by, or grown on, or acquired with, any property of ALLETE;

easements, restrictions, exceptions or reservations in any property and/or rights of way of ALLETE for the purpose of roads, pipe lines, transmission lines, distribution lines, removal of coal or other minerals or timber, and other like purposes, or for the joint or common use of real property, rights of way, facilities and/or equipment, and defects, irregularities and deficiencies in titles of any property and/or rights of way, which do not materially impair the use of such property and/or rights of way for the purposes for which such property and/or rights of way are held by ALLETE; or

any obligations or duties, affecting the property of ALLETE, to any municipality or public authority with respect to any franchise, grant, license or permit.
In addition, the lien of the mortgage is or may be subject to the following:

defects which ALLETE has the right to cure and which do not impair the use of such properties by ALLETE;

possible defects in title to reservoir lands, easements or rights of way, any property not costing in excess of $25,000, or lands or rights held for flowage, flooding or seepage purposes, or riparian rights;

vendors’ liens, purchase money mortgages and liens on property that already exist at the time ALLETE acquires that property;

liens for labor, materials, supplies or other objects given priority by law; and

liens for taxes, assessments or other governmental charges given priority by law.
ALLETE has reserved the right to amend the mortgage to restate the definition of “excepted encumbrances” to mean substantially the following:

tax liens, assessments and other governmental charges or requirements which are not delinquent or which are being contested in good faith and by appropriate proceedings or of which at least ten business days’ notice has not been given to ALLETE’s general counsel or to such other person designated by ALLETE to receive such notices;

mechanics’, workmen’s, repairmen’s, materialmen’s, warehousemen’s and carriers’ liens, other liens incident to construction, liens or privileges of any of ALLETE’s employees for salary or wages earned, but not yet payable, and other liens, including without limitation liens for worker’s compensation awards, arising in the ordinary course of business for charges or requirements which are not delinquent or which are being contested in good faith and by appropriate proceedings or of which at least ten business days’ notice has not been given to ALLETE’s general counsel or to such other person designated by ALLETE to receive such notices;

specified judgment liens;

easements, leases, reservations or other rights of others (including governmental entities) in, and defects of title in, ALLETE’s property;

liens securing indebtedness or other obligations relating to real property ALLETE acquired for specified transmission, distribution or communication purposes or for the purpose of obtaining rights-of-way;

specified leases and leasehold, license, franchise and permit interests;

liens resulting from law, rules, regulations, orders or rights of governmental authorities and specified liens required by law or governmental regulations;

liens to secure public obligations, rights of others to take minerals, timber, electric energy or capacity, gas, water, steam or other products produced by ALLETE or by others on ALLETE’s property;

rights and interests of persons other than ALLETE arising out of agreements relating to the common ownership or joint use of property, and liens on the interests of those persons in such property;

restrictions on assignment and/or requirements of any assignee to qualify as a permitted assignee and/or public utility or public services corporation;

liens which have been bonded for the full amount in dispute or for the payment of which other adequate security arrangements have been made;

certain easements, ground leases and rights-of-way for the purpose of roads, pipelines, transmission lines, distribution lines, communication lines, railways, removal or transportation of coal, lignite, gas, oil or other minerals or timber, and other like purposes, or for the joint or common use of real property, rights-of-way, facilities and/or equipment, so long as such grant shall not materially impair the use of the property or rights-of-way for the purposes for which such property or rights-of-way are held by ALLETE; and

certain prepaid liens. (See Thirty-first Supplemental Indenture, Article IV.)
The mortgage does not create a lien on the following “excepted property”:

cash and securities;

merchandise, equipment, materials or supplies held for sale or other disposition;

fuel, oil and similar materials consumable in the operation of the properties of ALLETE;

aircraft, automobiles and other vehicles, and materials and supplies for repairing and replacing the same;

timber, minerals, mineral rights and royalties;

receivables, contracts, leases and operating agreements; and

materials or products, including electric energy, that ALLETE generates, produces or purchases for sale or use by ALLETE.
No stock, properties or other assets of ALLETE’s subsidiaries are subject to the mortgage.
The mortgage contains provisions that impose the lien of the mortgage on property acquired by ALLETE after the date of the mortgage, other than “excepted property.” However, if ALLETE consolidates or merges with, or conveys or transfers all or substantially all of ALLETE’s mortgaged property to another corporation, the lien created by the mortgage will generally not cover the property of the successor company, other than the property it acquires from ALLETE and improvements, replacements and additions to that property. (See Mortgage, Section 87.)
The mortgage provides that the mortgage trustees shall have a lien upon the mortgaged property for the payment of their reasonable compensation, expenses and disbursements and for indemnity against certain liabilities. This lien takes priority over the lien securing the first mortgage bonds. (See Mortgage, Section 96.)

ALLETE has reserved the right to amend the mortgage to restate the description of the “excepted property,” or property of ALLETE not covered by the lien of the mortgage, to exclude from the lien of the mortgage substantially the following types of property:

all cash, deposit accounts, securities and all policies of insurance on the lives of ALLETE’s officers not paid or delivered to or deposited with or held by the corporate mortgage trustee or required so to be;

all contracts, leases, operating agreements and other agreements of all kinds (other than ALLETE’s franchises, permits and licenses that are transferable and necessary for the operation of the mortgaged property), contract rights, bills, notes and other instruments, revenues, income and earnings, all accounts, accounts receivable, rights to payment, payment intangibles and unbilled revenues, rights created by statute or governmental action to bill and collect revenues or other amounts from customers or others, credits, claims, demands and judgments;

all governmental and other licenses, permits, franchises, consents and allowances (other than ALLETE’s franchises, permits and licenses that are transferable and necessary for the operation of the mortgaged property);

all unrecorded easements and rights of way;

all intellectual property rights and other general intangibles;

all vehicles, movable equipment, aircraft and vessels and all parts, accessories and supplies used in connection with any of the foregoing;

all personal property of such character that the perfection of a security interest therein or other lien thereon is not governed by the Uniform Commercial Code in effect where ALLETE is organized;

all merchandise and appliances acquired for the purpose of resale in the ordinary course and conduct of ALLETE’s business, and all materials and supplies held for consumption in operation or held in advance of use thereof for fixed capital purposes;

all electric energy and capacity, gas, steam and other materials and products generated, manufactured, produced or purchased by ALLETE for sale, distribution or use in the ordinary course and conduct of ALLETE’s business;

all property which is the subject of a lease agreement designating ALLETE as lessee, and all ALLETE’s right, title and interest in and to the property and in, to and under the lease agreement, whether or not the lease agreement is intended as security, and the last day of the term of any lease or leasehold which may become subject to the lien of the mortgage; and

all property which subsequent to September 1, 1945 has been released from the lien of the mortgage and any improvements, extensions and additions to such properties and renewals, replacements, substitutions of or for any parts thereof. (See Thirty-first Supplemental Indenture, Article IV.)
Issuance of Additional First Mortgage Bonds.   The maximum principal amount of first mortgage bonds which may be issued under the mortgage is not limited so long as it meets the issuance tests set forth in the mortgage, which are generally described below. First mortgage bonds of any series may be issued from time to time on the basis of:
(1)
60 percent of property additions after adjustments to offset retirements;
(2)
retirement of first mortgage bonds or qualified lien bonds; and
(3)
deposit of cash.
With certain exceptions in the case of (2) above, ALLETE may not issue first mortgage bonds unless it meets the “net earnings” test set forth in the mortgage, which requires adjusted net earnings before income taxes for 12 out of the preceding 15 months of at least twice the annual interest requirements on all first mortgage bonds at the time outstanding, including the additional issue, and on all indebtedness of prior rank. Such adjusted net earnings are computed after provision for retirement and depreciation of property equal to $750,000 plus, for each of the 12 calendar months selected for the net earnings test, 1/12th of

two percent of the net additions to depreciable mortgaged property made after June 30, 1945 and prior to the beginning of the calendar year within which that calendar month is included. It is expected that the first mortgage bonds offered by this prospectus will be issued upon the basis of the retirement of first mortgage bonds or property additions.
Property additions mean all mortgaged property acquired by ALLETE by purchase, consolidation, merger, donation, construction, erection or in any way whatsoever, subsequent to June 30, 1945, or in the process of construction or erection in so far as actually constructed or erected subsequent to June 30, 1945.
ALLETE has the right to amend the mortgage without any consent or other action by holders of any series of first mortgage bonds, including the holders of first mortgage bonds offered by this prospectus, so as to include nuclear fuel as well as similar or analogous devices or substances as property additions. (See Fifth Supplemental Indenture, Section 2.)
The mortgage contains certain restrictions upon the issuance of first mortgage bonds on the basis of property additions subject to liens prior to the mortgage lien and upon the increase of the amount of such liens. (See Mortgage, Sections 4-8, 20, 23-30, and 46.)
Mortgage Amendment-Recalibration of Funded Property.   ALLETE has the right to amend the mortgage to change the definition of “funded property,” as long as ALLETE has delivered to the corporate mortgage trustee an independent engineer’s certificate referred to as a “funded property certificate.” This funded property certificate will describe all or a portion of mortgaged property which has a fair value not less than 10/6ths of the sum of the principal amount of the first mortgage bonds outstanding and the principal amount of the first mortgage bonds that ALLETE is entitled to have authenticated on the basis of retired first mortgage bonds. Once this funded property certificate is delivered to the corporate mortgage trustee, the definition of “funded property” will mean any mortgaged property described in the funded property certificate. Property additions will become funded property when used under the mortgage for the issuance of bonds, the release or retirement of funded property, or the withdrawal of cash deposited with the corporate mortgage trustee for the issuance of bonds or the release of funded property. (See Thirty-first Supplemental Indenture, Article IV.)
Release and Substitution of Property.   Property may be released without the sale or disposition of such property upon the basis of:
(1)
deposit with the corporate mortgage trustee of cash or, to a limited extent, purchase money mortgages;
(2)
property additions acquired by ALLETE in the last five years, after adjustments in certain cases to offset retirement and after making adjustments for qualified lien bonds outstanding against property additions; and/or
(3)
waiver of the right to issue first mortgage bonds,
in each case without applying any earnings test. Cash may be withdrawn upon the bases stated in (2) and (3) above.
When property released is not funded property, property additions used to effect the release may again, in certain cases, become available as credits under the mortgage, and the waiver of the right to issue first mortgage bonds to effect the release may, in certain cases, cease to be effective as such a waiver. Similar provisions are in effect as to cash proceeds of such property. The mortgage contains special provisions with respect to qualified lien bonds pledged, and disposition of moneys received on pledged prior lien bonds. (See Mortgage, Sections 5, 31, 32, 37, 46-50, and 59-63.)
ALLETE has reserved the right to amend the mortgage and the provisions discussed in the foregoing paragraphs under this “Release and Substitution of Property” subheading describing the release and substitution of mortgaged property as follows:

to eliminate the five-year limit referred to in clause (2) above; and

to specify that releases of property can be made on the basis of (i) the aggregate principal amount of first mortgage bonds that ALLETE would be entitled to issue on the basis of retired qualified lien
 
11

 
bonds; or (ii) 10/6ths of the aggregate principal amount of first mortgage bonds that ALLETE would be entitled to issue on the basis of retired first mortgage bonds, in each case with the entitlement being waived by operation of the release.
In addition, ALLETE has reserved the right to amend the mortgage to permit release of unfunded property if after such release at least one dollar of unfunded property remains subject to the lien of the mortgage. (See Thirty-first Supplemental Indenture, Article IV.)
Modification of the Mortgage.   The rights of holders of first mortgage bonds may be modified with the consent of the holders of 6623 percent of the aggregate principal amount of the outstanding first mortgage bonds and, if less than all series of first mortgage bonds are affected, the consent also of the holders of 6623 percent of the aggregate principal amount of all of the outstanding first mortgage bonds of each series affected. ALLETE has reserved the right to amend the mortgage to provide that such modifications can be made with the consent of the holders of a majority in aggregate principal amount of then outstanding mortgage bonds, considered as one class, or if less than all of the series of mortgage bonds outstanding are directly affected by a proposed amendment or modification, then the consent of the holders of only a majority in aggregate principal amount of the outstanding mortgage bonds of all series that are directly affected, considered as one class. In general, no modification of the terms of payment of principal and interest, and no modification affecting the lien or reducing the percentage required for modification, is effective against any holder of first mortgage bonds without his consent. (See Mortgage, Article XIX; Twenty-first Supplemental Indenture, Section 3; and Thirty-first Supplemental Indenture, Article IV.)
ALLETE has reserved the right to amend the mortgage to permit ALLETE and the mortgage trustees, without the consent of any holder of mortgage bonds, to enter into one or more supplemental indentures for any of the following purposes:

to evidence the assumption by any permitted successor of ALLETE’s covenants in the mortgage and in the first mortgage bonds;

to add one or more covenants or other provisions for the benefit of the holders of all or any series of mortgage bonds, or to surrender any right or power conferred upon ALLETE and to make an occurrence of a default in performance of any such additional covenants, an additional “default”;

to correct or amplify the description of any property at any time subject to the lien of the mortgage, or better to assure, convey and confirm unto the mortgage trustees any property subject or required to be subjected to the lien of the mortgage, or to subject to the lien of the mortgage additional property;

to change or eliminate or add any new provision to the mortgage; provided, however, that no such change, elimination or addition will adversely affect the interests of the holders of first mortgage bonds of any series in any material respect;

to establish the form or terms of mortgage bonds of any other series as permitted by the mortgage;

to provide for the procedures required to permit ALLETE to utilize, at its option, a non-certificated system of registration for all or any series of first mortgage bonds;

to change any place where principal, premium, if any, and interest shall be payable, mortgage bonds may be surrendered for registration of transfer or exchange, and notices and demands to ALLETE may be served; and

to cure any ambiguity or inconsistency or to make any other changes or additions to the provisions of the mortgage if such changes or additions will not adversely affect the interests of the holders of first mortgage bonds of any series in any material respect. (See Thirty-first Supplemental Indenture, Article IV.)
Defaults and Notice Thereof.   The following are defaults under the mortgage:

failure to pay principal of any first mortgage bond when due;

failure to pay interest on any first mortgage bond for 60 days after that interest is due;

failure to pay any installments of funds for retirement of first mortgage bonds for 60 days after that installment is due;
 
12

 

failure to pay principal of or interest on any qualified lien bond beyond any applicable grace period for the payment of that principal or interest;

certain events in bankruptcy, insolvency or reorganization pertaining to ALLETE; and

the expiration of 90 days following notice by the corporate mortgage trustee or holders of 15 percent of the first mortgage bonds relating to the failure by ALLETE to perform its covenants under the mortgage. (See Mortgage, Section 65.)
The mortgage trustees may withhold notice of default, except in the case of failure to pay principal, interest or installment of any fund for retirement of first mortgage bonds, if they determine that withholding the notice is in the interest of the holders of first mortgage bonds. (See Mortgage, Section 66.)
Remedies
Acceleration of Maturity.   If a default under the mortgage occurs, then the corporate mortgage trustee, by written notice to ALLETE, or the holders of at least 25% in principal amount of the outstanding first mortgage bonds, by written notice to ALLETE and the corporate mortgage trustee, may declare the principal amount of all of the first mortgage bonds to be due and payable immediately, and upon the giving of such notice, such principal amount and accrued and unpaid interest will become immediately due and payable. (See Mortgage, Section 67.)
There is no automatic acceleration, even in the event of ALLETE’s bankruptcy, insolvency or reorganization.
Annulment of Acceleration.   At any time after such a declaration of acceleration has been made but before any sale of the mortgaged property, the holders of a majority in principal amount of all outstanding first mortgage bonds may annul such declaration of acceleration, by written notice to ALLETE and the mortgage trustees, if the default under the mortgage giving rise to such declaration of acceleration has been cured, and ALLETE has paid or deposited with the corporate mortgage trustee a sum sufficient to pay:

all overdue interest on all outstanding first mortgage bonds;

the principal of and premium, if any, on the outstanding first mortgage bonds that have become due otherwise than by such declaration of acceleration; and

all reasonable expenses and charges due to the mortgage trustees, their agents and (to the extent permitted by law) their attorneys. (See Mortgage, Section 67.)
Mortgage Trustees’ Powers.   Subject to the mortgage, under specified circumstances and to the extent permitted by law, if a default under the mortgage occurs, the mortgage trustees shall be entitled to the appointment of a receiver for the mortgaged property, and are entitled to all other remedies available under applicable law. (See Mortgage, Sections 70 and 72.)
Control by Holders.   The holders of a majority in principal amount of the first mortgage bonds may direct the time, method and place of conducting any proceedings for any remedy available to the mortgage trustees or exercising any trust or power conferred on the mortgage trustees. The mortgage trustees are not obligated to comply with directions that conflict with law or other provisions of the mortgage or that the corporate mortgage trustee determines in good faith would involve the mortgage trustees in personal liability, would be unjustifiably prejudicial to non-assenting holders or would be in circumstances where indemnity would not be sufficient. (See Mortgage, Section 71.)
Limitation on Holders’ Right to Institute Proceedings.   No holder of first mortgage bonds will have any right to institute any proceeding under the mortgage, or any remedy under the mortgage, unless:

the holder has previously given to the mortgage trustees written notice of a default under the mortgage;

the holders of 25% in aggregate principal amount of the outstanding first mortgage bonds of all series have made a written request to the mortgage trustees and have offered the mortgage trustees reasonable opportunity and indemnity satisfactory to the mortgage trustees to institute proceedings; and
 
13

 

the mortgage trustees have failed to institute any proceeding for 60 days after notice;
provided that no holder or holders of first mortgage bonds shall have any right in any manner to affect or prejudice the lien of the mortgage or to obtain priority over other holders of outstanding first mortgage bonds. However, these limitations do not apply to the absolute and unconditional right of a holder of a first mortgage bond to institute suit for payment of the principal, premium, if any, or interest on the first mortgage bond on or after the applicable due date. (See Mortgage, Section 80.)
Consolidation, Merger and Conveyance of Assets.   The mortgage provides that ALLETE may consolidate with or merge into any other corporation or convey, transfer or lease as, or substantially as, an entirety to any corporation the mortgaged property, if:

(a) the surviving or successor corporation to such merger or consolidation has authority to carry on the electric, gas, steam or hot water business, or (b) the successor corporation which acquires by conveyance or transfer or which leases ALLETE’s mortgaged property as, or substantially as, an entirety, is authorized to acquire, lease or operate the mortgaged property so conveyed or transferred;

such merger, consolidation, conveyance, transfer or lease is upon such terms as to preserve, and in no respect impair, the lien and security of the mortgage and the rights and powers of the mortgage trustees and the holders of first mortgage bonds;

the survivor or successor corporation expressly assumes by supplemental indenture ALLETE’s obligations on all first mortgage bonds then outstanding and under the mortgage; and

in the case of a lease, such lease is made expressly subject to termination by ALLETE or by the mortgage trustees and by the purchaser of the property so leased at any sale thereof at any time during the continuance of a default under the mortgage. (See Mortgage, Section 85.)
In the case of the conveyance or other transfer of the mortgaged property as, or substantially as, an entirety to another corporation, upon the satisfaction of all the conditions described above, such corporation would succeed and be substituted for ALLETE under the mortgage. (See Mortgage, Section 86.) ALLETE has reserved the right to amend the mortgage to provide that if ALLETE transfers all or substantially all of the mortgaged property as an entirety to a successor corporation as described above, ALLETE may be released of all of its obligations under the mortgage or any first mortgage bonds assumed by such successor. (See Thirty-first Supplemental Indenture, Article IV.)
The mortgage does not prevent or restrict any conveyance or other transfer, or lease, of any part of the mortgaged property that does not constitute the entirety, or substantially the entirety, of the mortgaged property.
Although ALLETE’s successor may, in its sole discretion, subject to the lien of the mortgage any property then owned or thereafter acquired by the successor, the lien of the mortgage generally will not cover the property of the successor other than the mortgaged property it acquires from ALLETE and improvements, extensions and additions to such property and renewals, replacements and substitutions thereof, within the meaning of the mortgage. (See Mortgage, Section 87.)
The terms of the mortgage do not restrict mergers in which ALLETE is the surviving entity.
Information about the Mortgage Trustees.   The Bank of New York Mellon is the corporate mortgage trustee and Andres Serrano is the individual mortgage trustee. In addition to acting as corporate mortgage trustee, The Bank of New York Mellon may also act as trustee under other indentures, trusts and guarantees of ALLETE and its affiliates from time to time.
Satisfaction and Discharge of Mortgage.   The mortgage may be satisfied and discharged if and when ALLETE provides for the payment of all of the first mortgage bonds and all other sums due under the mortgage. (See Mortgage, Section 106.)
Evidence to be Furnished to the Mortgage Trustee.   ALLETE will provide to the mortgage trustee an annual statement by an appropriate officer as to ALLETE’s compliance with all conditions and covenants under the mortgage. (See Trust Indenture Act of 1939, Section 314(a)(4).)
