(b) The holders of Preferred shares at the time outstanding shall be entitled to receive dividends when and as declared by the Board of Directors, out of the surplus or net profits of the Corporation, payable in the case of each series at the annual dividend rate for that particular series theretofore fixed by the Board of Directors as hereinbefore provided. Such dividends on Preferred shares shall be cumulative from the date or dates theretofore fixed for the purpose by the Board of Directors, as hereinbefore provided, so that if dividends on all outstanding shares of each particular series of the Preferred shares, at the annual dividend rate fixed by the Board of Directors, as hereinbefore provided, shall not have been paid or declared and set apart for payment for all past dividend periods and for the current dividend periods, the deficiency shall be fully paid or dividends equal thereto declared and set apart for payment at said rate, but without interest, before any dividends on the Common shares shall be paid or declared and set apart for payment. No dividends shall be paid or declared and set apart for payment on any series of Preferred shares for any particular dividend period unless at the same time all unpaid dividends, if any, on all the outstanding Preferred shares for all dividend periods terminating prior to or concurrently with the termination of such particular dividend period shall be paid or declared and set apart for payment thereon. Dividends may be paid upon the Common shares only when dividends at the respective annual dividend rates fixed by the Board of Directors, as hereinbefore provided, upon all the outstanding Preferred shares shall have been paid or declared and set apart for payment for all past dividend periods and for the then current dividend periods, but whenever there shall have been paid or declared and set apart for payment all such dividend upon the Preferred shares, as aforesaid, then dividends upon the Common shares may be declared payable then or thereafter out of any surplus or net profits then remaining. The holders of shares of each series of the Preferred shares shall not be entitled to receive any dividends thereon other than the aforesaid dividends at the annual dividend rate for the particular series fixed by the Board of Directors, as hereinbefore provided. Dividends may also be declared and paid in cash out of depletion reserves in the manner and to the extent provided by law. (c) In the event of any liquidation, dissolution or winding up of the affairs of the Corporation or any distribution of capital, whether voluntary or involuntary, the holders of Preferred shares at the time outstanding shall be entitled to be paid the amount fixed by the Board of Directors, as hereinbefore provided, before any distribution or payment shall be made to the holders of Common shares. The holders of the Preferred shares shall not be entitled to receive any distributive amounts upon the liquidation, dissolution or winding up of the affairs of the Corporation or upon any distribution of capital other than the distributive amounts at the rates for the respective series fixed by the Board of Directors, as hereinbefore provided, but, after such payment to the holders of the Preferred shares, the remaining assets and funds of the Corporation (subject to the rights of any class of shares hereafter authorized) shall be divided and distributed among the holders of the Common shares alone according to their respective shares. (d) A consolidation, merger or amalgamation of the Corporation with or into any other corporation or corporations shall not be deemed a distribution of assets of the Corporation within the meaning of any of the provisions hereof. (e) Except as hereinafter otherwise provided, each holder of record of Preferred or Common shares shall be entitled to one vote for each share of stock held by him, except that holders of Preferred shares shall not be entitled to notice of or to vote at any annual or special meeting of shareholders called for the purpose of redeeming the whole or any part of the Preferred shares at the time outstanding, and except that at all elections for Directors, each holder of Preferred or Common shares shall be entitled to as many votes as shall equal the number of his Preferred or Common shares multiplied by the number of Directors to be elected, and may cast all of such votes in person or by proxy for a single Director, or may distribute them among the number to be voted for, or any two or more of them as he may see fit. (f) No holder of Preferred shares shall be entitled as such, as a matter of right, to subscribe for or purchase any part of any new or additional issue of stock of any class whatsoever, or of securities convertible into stock of any class whatsoever, whether now or hereafter authorized or whether issued for cash, for a consideration other than cash or by way or dividend. (g) Upon any issue for money or other consideration of any shares of the Corporation that may be authorized from time to time, no holder of shares, irrespective of the kind of such shares, shall have any preemptive or other right to subscribe for, purchase or receive any proportionate or other share of the shares so issued, but the Board of Directors may dispose of all or any portion of such shares as and when it may determine free of any such rights, whether by offering the same to shareholders or by sale of other disposition, as said Board may deem advisable. (h) The Corporation may redeem the whole or any part of the Preferred shares at the time outstanding, or the whole or any part of any series thereof, at any time or from time to time, upon the terms fixed by the Board of Directors as hereinbefore provided for the redemption of the Preferred shares to be redeemed; provided, however, that no Preferred shares of the $6 Series, the $4.20 Series or the $2.15 Series shall be redeemed without either the written consent, or the affirmative vote at any annual meeting or at any special meeting called for that purpose, of the holders of record of a majority of the Common shares issued and outstanding. If less than all of the shares of any particular series of the Preferred shares are to be redeemed, the shares of such series to be redeemed shall be selected in such manner as the Board of Directors or the Executive Committee shall determine. The Board of Directors by the vote or consent of two-thirds (2/3) of all of the members thereof shall have the power to select for redemption any particular share or shares of the Preferred shares to be redeemed, designating the share or shares of such Preferred shares so selected by the number or numbers appearing on the then outstanding certificate or certificates representing the shares so selected. Notice of intention of the Corporation to redeem Preferred shares and of the date and place of redemption shall be mailed not less than thirty (30) days (or in case the Board of Directors shall have fixed a longer period as hereinbefore provided, then not less than such longer period) before the date of redemption to each holder of record of the shares to be redeemed, at his last known post office address as shown by the records of the Corporation. The holders of any Preferred shares so called for redemption shall, on the redemption date specified in such notice, cease to be shareholders of the Corporation with respect to such shares and all rights with respect to such Preferred shares so called for redemption shall, on such redemption date, cease and terminate except only the right of the holders thereof to receive the redemption price therefor without interest. At any time after such notice of redemption of any Preferred shares has been mailed or otherwise given, the Corporation may deposit, or may cause its nominee to deposit, the aggregate redemption price (or the portion thereof not already paid in the redemption of shares so to be redeemed) with any bank or trust company in the State of Montana having a capital and undivided surplus of not less than $500,000 named in a notice mailed to holders of the shares called for redemption and represented by certificates not theretofore surrendered, payable in the proper amounts to the respective orders of the record holders of such shares to be redeemed on endorsement, if required, and surrender of their certificates for said shares, and from and after the making of such deposit said holders shall have no interest in or claim against the Corporation or its nominee, with respect to said shares, but shall be entitled only to receive said moneys from said bank or trust company, without interest, on endorsement, if required, and surrender of their certificates as aforesaid. The Corporation shall be entitled to receive from any such bank or trust company the interest, if any, allowed by said bank or trust company on any moneys deposited as in this paragraph provided, and the holders of any shares so redeemed shall have no claim to any such interest. Any moneys so deposited and remaining unclaimed at the end of six years from the date fixed for redemption shall, if thereafter requested by resolution of the Board of Directors or of the Executive Committee, be repaid to the Corporation, and in the event of such repayment to the Corporation, such holders of record of the shares so redeemed as shall not have made claim against such moneys prior to such repayment to the Corporation, shall be deemed to be unsecured creditors of the Corporation for an amount equivalent to the amount deposited as above-stated for the redemption of such shares and so repaid to the Corporation, but shall in no event be entitled to any interest. If such deposit shall be made by the nominee of the Corporation, as aforesaid, such nominee shall upon such deposit become the owner of the shares with respect to which such deposit is made, and certificates for shares may be issued to such nominee in evidence of such ownership. The Corporation may require any shares so called for redemption to be delivered, duly assigned to a nominee of the Corporation upon payment by such nominee in the manner hereinabove provided of all amounts payable on such redemption with respect to said shares. Any shares delivered to or acquired by the nominee of the Corporation under the provisions hereof shall be converted into or exchanged for such other securities of the Corporation and on such terms as on or before such delivery or acquisition may have been provided by the Corporation in accordance with the next three paragraphs hereof. The Corporation from time to time may resell any of its own shares purchased or otherwise acquired by it as herein provided for at such price as may be fixed by its Board of Directors or Executive Committee. The Corporation, in order to acquire funds with which to redeem any Preferred shares of any class, may issue and sell shares of any class then authorized but unissued, bonds, notes, evidences of indebtedness or other securities. The Board of Directors of the Corporation may at any time authorize the conversion or exchange of the whole or any particular share or shares of the outstanding Preferred shares of any class, with the consent of the holder or holders thereof, into or for shares of any other class at the time of such consent authorized but unissued and may fix the terms and conditions upon which such conversion or exchange may be made; provided that without the consent of the holders of record of two-thirds (2/3) of the Common shares outstanding given at a meeting of the holders of the Common shares called and held as provided by the Bylaws or given in writing without a meeting, the Board of Directors shall not authorize the conversion or exchange of any Preferred shares of any class into or for Common shares or authorize the conversion or exchange of any Preferred shares of any class into or for Preferred shares of any other class, if by such conversion or exchange the amount which the holders of the shares so converted or exchanged would be entitled to receive either as dividends or shares in distribution of assets in preference to the Common shares would be increased. The Board of Directors shall have full power and authority, subject to the limitations and provisions herein contained, to prescribe the manner in which and the terms and conditions upon which Preferred shares shall be redeemed from time to time. (i) Except as herein otherwise provided, upon the vote of a majority of all of the Directors of the Corporation and of the holders of record of a majority of the total number of shares then issued and outstanding and entitled to vote on such question as herein stipulated, irrespective of class (or if the vote of a larger number or different proportion of shares is required by the laws of the State of Montana, notwithstanding the above agreement of the shareholders of the Corporation to the contrary, then upon the vote of the larger number or different proportion of shares so required), the Corporation may from time to time create or authorize one or more other classes of shares with such preferences, designations, rights, privileges, powers, restrictions, limitations and qualifications as may be determined by said vote, which may be the same as or different from the preferences, designations, rights, privileges, powers, restrictions, limitations and qualifications of the classes of shares of the Corporation then authorized. Any vote authorizing the creation of a new class of shares may provide that all moneys payable by the Corporation with respect to any class of shares thereby authorized shall be paid in the money of any foreign country named therein or designated by the Board of Directors pursuant to authority therein granted. Any such vote may authorize any shares of any class then authorized but unissued to be issued as shares of such new class or classes. So long as any of the Preferred shares are outstanding, the Corporation shall not, without the consent (given by a vote at a meeting called for that purpose) of the holders of at least two- thirds of the total number of the Preferred shares then outstanding. 1. Create or authorize any new shares ranking prior to the Preferred shares as to dividends, in liquidation, dissolution, winding up or distribution, or create or authorize any security convertible into such shares; or 2. Amend, alter, change or repeal any of the express terms of the Preferred shares then outstanding in a manner substantially prejudicial to the holders thereof. (j) All shares of the Corporation without nominal or par value, whether authorized by these Articles or by subsequent increase of capital or pursuant to any amendment hereof, may be issued from time to time for such consideration as may be fixed from time to time by the Board of Directors, and authority to the Board of Directors so to fix such consideration is hereby granted by the shareholders; and any and all shares so issued, the full consideration for which shall have been paid or delivered, shall be conclusively deemed to be fully paid and nonassessable and the holders thereof shall not be liable to the Corporation or its creditors in respect thereof. At the time of the issue of any shares without nominal or par value, the Board of Directors may determine conclusively in the exercise of their reasonable discretion what capital valuation shall be placed upon any property (other than money) acquired by the Corporation in payment upon original issue of any of its shares without nominal or par value. (k) The Corporation may issue securities, notes, bonds, debentures or other obligations convertible into shares of any class, in the amounts and on such terms as may be provided by resolution of the Board of Directors; provided, however, that the shares issued upon conversion thereof shall not have prior or superior rights and preferences to the shares of any class outstanding at the time the convertible securities, notes, bonds, debentures or other obligations are issued, and the issuance of such shares shall not substantially prejudice the holders of shares of any class outstanding at the time such convertible securities, notes, bonds, debentures or other obligations are issued. 1. The Corporation may issue notes, bonds, debentures and other obligations of the Corporation in such amounts and upon such terms and conditions as may be authorized by resolution of the Board of Directors. ARTICLE VIII. Unless the laws of the State of Montana otherwise provide, any action which at any meeting of shareholders requires the vote, assent or consent of two- thirds (2/3) in interest of all the shareholders or of two- thirds (2/3) in interest of each class of shareholders having voting powers, or which requires such assent or consent in writing to be filed, may be taken upon the assent of and the assent given and filed of two-thirds (2/3) in interest of the shareholders present and voting at such meeting in person or by proxy; provided that where assent by classes is required, such assent shall be given by two- thirds (2/3) in interest of each class so present and voting. ARTICLE IX. The Board of Directors may appoint from the Directors an Executive Committee, of which a majority shall constitute a quorum, and to such extent as shall be provided in the Bylaws, such Executive Committee shall have and may exercise all of the delegable powers of the Board of Directors, including power to cause the seal of the Corporation to be affixed to all papers that may require it. The power of appointment of committees (other than the Executive Committee) and of Officers (other than the President, the Vice Presidents, the Secretary and the Treasurer) and other persons employed by the Company may to the extent permitted by the Bylaws be delegated by the Board of Directors to the President or to the Executive Committee. The Board of Directors shall have the power from time to time to fix and to determine and to vary the amount of the working capital of the Corporation, and to direct and determine the use and disposition of any surplus or net profits over and above the capital paid in. The Board of Directors from time to time shall determine whether and to what extent, and at what times and places and under what conditions and regulations, the accounts and books of the Corporation, or any of them, shall be open to the inspection of the shareholders, and no shareholder shall have any right to inspect any account or book or document of the Corporation, except as conferred by Statute or authorized by the Board of Directors, or by a resolution of the shareholders. ARTICLE X. The shareholders may alter or amend the Bylaws of the Corporation by a majority vote (or if required by the laws of the State of Montana, a larger number or different proportion of the shares outstanding) of all the outstanding shares of the Corporation entitled to vote given at any meeting duly held as provided in the Bylaws, the notice of which includes notice of the proposed alterations or amendment. The Board of Directors may also alter or amend the Bylaws at any time by affirmative vote of a majority (or if required by the laws of the State of Montana, a larger number or different proportion of the members of the Board of Directors) of the Board of Directors given at a duly convened meeting of the Board of Directors, the notice of which includes notice of the proposed alterations or amendments, subject to the power of shareholders to change or repeal such Bylaws; provided that the Board of Directors shall not make or alter any Bylaw fixing their qualifications or changing the number of shares required to constitute a quorum for a shareholders' meeting. ARTICLE XI. A. In addition to any affirmative vote required by law or under any other provision of these Restated Articles of Incorporation, and except as otherwise expressly provided in paragraph B., a Business Combination (as hereinafter defined) shall require the affirmative vote of the holders of at least 70 percent of the outstanding shares of Capital Stock (as hereinafter defined) of the Corporation entitled to vote generally in the election of Directors ("Voting Shares"). Such affirmative vote shall be required notwithstanding the fact that no vote may be required, or that some lesser percentage may be specified, by law or in any agreement with any national securities exchange or otherwise. B. The provisions of paragraph A. of this Article shall not be applicable to any particular Business Combination, and such Business Combination shall require only such affirmative vote as is required by law and any other provision of these Restated Articles of Incorporation, if all of the conditions specified in subparagraphs 1. or 2. shall have been satisfied: 1. The Business Combination shall have been approved by two-thirds (whether such approval is made prior to or subsequent to the acquisition of beneficial ownership of the Voting Shares that caused the 10% Shareholder [as hereinafter defined] to become a 10% Shareholder) of the Continuing Directors (as hereinafter defined); or 2. All of the following conditions shall have been met: (a) The aggregate amount of the cash and the Fair Market Value (as hereinafter defined) as of the date of the consummation of the Business Combination of consideration other than cash to be received per share by holders of Common shares in such Business Combination shall be at least equal to the highest amount determined under clauses (i) and (ii) below: (i) (if applicable) The highest per share price (including any brokerage commissions, transfer taxes and soliciting dealers' fees) paid by or on behalf of the 10% Shareholder for any Common shares in connection with the acquisition by the 10% Shareholder of beneficial ownership of Common shares (A) within the two-year period immediately prior to the first public announcement of the proposed Business Combination (the "Announcement Date") or (B) in the transaction in which it became a 10% Shareholder, whichever is higher; and (ii) The Fair Market Value per Common share on the Announcement Date or on the date on which the 10% Shareholder became a 10% Shareholder (such latter date referred to in this Article as the "Determination Date"), whichever is higher. All per share prices and Fair Market Values shall be adjusted to reflect any intervening stock splits, stock dividends and reverse stock splits. (b) The aggregate amount of the cash and the Fair Market Value as of the date of the consummation of the Business Combination of consideration other than cash to be received per share by holders of shares of any class or series of outstanding Capital Stock, other than Common shares, shall be at least equal to the highest amount determined under clauses (i), (ii) and (iii) below: (i) (if applicable) The highest per share price (including any brokerage commissions, transfer taxes and soliciting dealers' fees) paid by or on behalf of the 10% Shareholder for any share of such class or series of Capital Stock in connection with the acquisition by the 10% Shareholder of beneficial ownership of shares of such class or series of Capital Stock (A) within the two-year period immediately prior to the Announcement Date or (B) in the transaction in which it became a 10% Shareholder, whichever is higher. (ii) The Fair Market Value per share of such class or series of Capital Stock on the Announcement Date or on the Determination Date, whichever is higher; and (iii) (if applicable) The highest preferential amount per share to which the holders of shares of such class or series of Capital Stock would be entitled in the event of any voluntary or involuntary liquidation, dissolution or winding up of the corporation, regardless of whether the Business Combination to be consummated constitutes such an event. All per share prices and Fair Market Values shall be adjusted for intervening stock splits, stock dividends and reverse stock splits. The provisions of this subparagraph (b) shall be required to be met with respect to every class or series of outstanding Capital Stock, whether or not the 10% Shareholder has previously acquired beneficial ownership of any shares of a particular class or series of Capital Stock. (c) The consideration to be received by holders of a particular class or series of outstanding Capital Stock (including Common shares) shall be cash or in the same form as previously has been paid by or on behalf of the 10% Shareholder in connection with its direct or indirect acquisition of beneficial ownership of shares of such class or series of Capital Stock. If the consideration so paid for shares of any class or series of Capital Stock varied as to form, the form of consideration for such class or series of Capital Stock shall be either cash or the form used to acquire beneficial ownership of the largest number of shares of such class or series of Capital Stock previously acquired by the 10% Shareholder. (d) After such 10% Shareholder has become a 10% Shareholder and prior to the consummation of such Business Combination: (i) except as approved by two-thirds of the Continuing Directors, there shall have been no failure to declare and pay at the regular date therefor any full quarterly dividends (whether or not cumulative) in accordance with the terms of the outstanding Preferred shares; (ii) there shall have been (A) no reduction in the annual rate of dividend paid on the Common shares (except as necessary to reflect any stock split, stock dividend or subdivision of the Common Shares), except as shall have been approved by two-thirds of the Continuing Directors, and (B) an increase in such annual rate of dividends as necessary to reflect any reclassification (including any reverse stock split), recapitalization, reorganization or any similar transaction which has the effect of reducing the number of outstanding Common shares, unless the failure so to increase such annual rate shall have been approved by two-thirds of the Continuing Directors; and (iii) such 10% Shareholder shall have not become the beneficial owner of any additional Voting Shares except as part of the transaction which results in such 10% Shareholder becoming a 10% Shareholder and except in a transaction that, after giving effect thereto, would not result in any increase in the 10% Shareholder's percentage beneficial ownership of any class or series of Capital Stock. (e) After such 10% Shareholder has become a 10% Shareholder, such 10% Shareholder shall not have: (i) received the benefit, directly or indirectly (except proportionately as a shareholder), of any loans, advances, guarantees, pledges or other financial assistance or any tax credits or other tax advantages provided by the Corporation, whether in anticipation of or in connection with such Business Combination or otherwise; or (ii) made any major change in the Corporation's business or equity capital structure without the approval of two-thirds of the Continuing Directors. (f) A proxy or information statement describing the proposed Business Combination and complying with the requirements of the Securities Exchange Act of 1934 and the rules and regulations thereunder (or any subsequent provisions replacing such Act, rules or regulations) shall have been mailed to holders of outstanding Voting Shares of the Corporation at least thirty (30) days prior to the consummation of such Business Combination (whether or not such proxy or information statement is required to be mailed pursuant to such Act or subsequent provisions).

The text of the amendment so authorized is as follows, and has been inserted as a new, undesignated subparagraph at the end of Section (a) of Article VII of the Restated Articles of Incorporation: Fourth Series ------------- The Fourth Series of Preferred Stock of the Company (the "Fourth Series"), consists of 500,000 shares designated as "Preferred Stock, $6.875 Series," and has the relative rights, preferences and limitations as set fourth in these Restated Articles of Incorporation, and as follows: (A) The dividend rate for the Fourth Series shall be $6.875 per share per annum; quarterly periods ending January 31, April 30, July 31 and October 31 of each year hereby are established as the regular dividend periods for the shares of such Series and dividends for such periods shall be payable, in arrears, on February 1, May 1, August 1, and November 1 of each year; provided, however, the first dividend shall be payable, in arrears, on February 1, 1994, for the period from the date of the original issue through January 31, 1994; and dividends on shares of the Fourth Series shall be cumulative from the date of original issue; (B) The shares of the Fourth Series shall not be redeemable prior to November 1, 2003; the shares shall be redeemable, at the option of the Company, in whole or in part, at any time upon not less than thirty (30) days' notice, on and after November 1, 2003, at the redemption prices per share set forth below, plus, in each case, accumulated but unpaid dividends to the date of redemption: Redemption Period Price November 1, 2003 to October 31, 2004 $103.438 November 1, 2004 to October 31, 2005 $103.094 November 1, 2005 to October 31, 2006 $102.750 November 1, 2006 to October 31, 2007 $102.406 November 1, 2007 to October 31, 2008 $102.063 November 1, 2008 to October 31, 2009 $101.719 November 1, 2009 to October 31, 2010 $101.375 November 1, 2010 to October 31, 2011 $101.031 November 1, 2011 to October 31, 2012 $100.688 November 1, 2012 to October 31, 2013 $100.344 November 1, 2013 and thereafter $100.000 (C) The amount which shall be paid to the holders of shares of the Fourth Series in the event of any liquidation, dissolution or winding up of the affairs of the Company or any distribution of its capital, whether voluntary or involuntary, before any distribution or payment shall be made to the holders of Common Stock, shall be $100 per share, plus accumulated but unpaid dividends. D. The following amendment to its Articles of Incorporation was adopted by the shareholders of the corporation on May 8, 1990 and filed with the Secretary of the State on May 24, 1990, in the manner prescribed by the Montana Business Corporation Act. When this amendment was filed with the Secretary of the State the Article referenced as Article VI should have been referenced as Article VII. This was clerical error, the amendment approved by shareholders did reference Article VII, and is so referenced in the Restated Articles of Incorporation. Article VII was also addressed on March 24, 1998, at The Montana Power Company Board of Directors meeting, clarifying the intention concerning this amendment as follows: RESOLVED further, that the language in the first paragraph of Section VII of the Articles of Incorporation, when amended by shareholders in 1990 was intended to replace both the first and second sentences of that section and the attached Restated Articles of Incorporation have so replaced both sentences so that the following two sentences contained in the Restated Articles of 1988 are; ARTICLE VII. The aggregate number of shares which the Corporation has authority to issue is 65,000,000 shares without nominal or par value, consisting of 5,000,000 Preferred shares and 60,000,000 Common shares. At the date hereof, the aggregate number of shares, issued and unissued, itemized by class and series, if any, within each class is as follows: Issued Unissued Total --------- ---------- ---------- Common 23,750,936 36,249,064 60,000,000 Preferred: $6.00 Series 159,589 $4.20 Series 60,000 $2.15 Series 1,200,000 Undesignated 3,580,411 5,000,000 And, the following sentence replaces the above two sentences in the attached Restated Articles of Incorporation: ARTICLE VII.
