The total number of authorized shares of capital stock of the corporation is 2,860,000 shares, consisting of 60,000 shares of the par value of $100 each and 2,800,000 shares of the par value of $22 each, and divided into two classes, namely: (1) Preferred Stock, consisting of 60,000 shares of the par value of $100 each and designated "4.40% Cumulative Preferred Stock," and (2) Common Stock, consisting of 2,800,000 shares of the par value of $22 each. Any increase hereafter authorized in the total number of authorized shares of the par value of $100 each of Preferred Stock may consist of shares having such designation, dividend rate, redemption prices and terms, price payable in respect thereof in the event of the voluntary liquidation, dissolution or winding up of the corporation and provisions (if any) as to sinking fund or conversion into other shares, as shall be provided by the amendment to the Charter of the corporation authorizing such increase. The preferences, rights, privileges and powers and the restrictions, limitations or qualifications of the shares of the par value of $100 each of Preferred Stock (including the shares thereof designated "4.40% Cumulative Preferred Stock" and the shares of all other designations or series thereof that may be hereafter authorized) and the rights and powers of the shares of the par value of $22 each of Common Stock of the corporation shall be as hereinafter set forth. -3- The term "Preferred Stock, as hereinafter used, except where the context otherwise indicates or requires, shall mean and include only the shares of the par value of $100 each of Preferred Stock, of all designations or series, now or hereafter authorized. (1) The holders of shares of the Preferred Stock shall be entitled to receive, in respect of each share held, dividends upon the par value thereof at the annual rate specified in the designation or series of such share, payable quarter-yearly on the first day of January, April, July and October in each year, when and as declared by the Board of Directors, out of the surplus or net profits of the corporation. Such dividends shall be cumulative (a) as to the shares initially issued of any designation or series, from the date of issue or such other date as may be provided in the resolution of the Board of Directors authorizing the initial issue of shares of such designation or series and (b) as to all other shares of such designation or series, from the first day of the dividend period in which issued, and such dividends shall be paid, or declared and set apart for payment, before any dividends shall be declared or paid on, or set apart for, the Common stock, so that if, for any past dividend period or the current dividend period, dividends on the Preferred Stock shall not have been paid, or declared and set apart for payment, the deficiency shall be fully paid, or declared and funds set apart for the payment thereof, before any dividends shall be declared or paid on, or set apart for, the Common Stock. No dividend shall at any time be paid on, or set apart for, any share of the Preferred Stock of any designation or series unless at the same time there shall be paid on, or set apart for, all shares of the Preferred Stock then outstanding dividends in such amount that the holders of all shares of the Preferred Stock shall receive, or have set apart for them, a uniform percentage of the full annual dividend to which they are, respectively, entitled. The term "dividend period", as used herein, refers to each period of three consecutive calendar months ending on the day next preceding the date on which dividends, if declared, shall be payable. The holders of shares of the Preferred Stock shall not be entitled to receive any dividends thereon other than the dividends at the annual rate specified in the designation or series of such shares. All shares of the Preferred Stock at any time authorized, regardless of the designation or series thereof, shall constitute one class of stock and, excepting only as to the designations thereof, the rates of dividends payable thereon, the redemption prices and terms thereof, the prices payable in respect thereof in the event of the voluntary liquidation, dissolution or winding up of the -4- corporation and any provisions as to sinking fund or conversion into other shares, shall be of equal rank and confer equal rights upon the holders thereof. All shares of the Preferred Stock bearing the same designation at any time outstanding shall constitute one series of Preferred Stock; and all shares of any one designation or series of Preferred Stock shall be alike in all respects. Whenever full cumulative dividends as aforesaid upon the Preferred Stock (of all designations or series) and upon any other shares of stock having priority as to dividends over the Common Stock, then outstanding, for all past dividend periods and for the current dividend period shall have been paid, or declared and set apart for payment, the Board of Directors may declare dividends on the Common Stock of the corporation, subject to the restrictions hereinafter contained. (2) In the event of the involuntary liquidation, dissolution or winding up of the corporation, the holders of shares of the Preferred Stock then outstanding, regardless of the designation or series thereof, shall be entitled to be paid in full, out of the net assets of the corporation, the par value of their shares plus an amount equal to the accrued dividends on such shares, and no more, before any amount shall be paid or distributed to the holders of shares of the Common Stock. In the event of the voluntary liquidation, dissolution or winding up of the corporation, the holders of shares of the 4.40% Cumulative Preferred Stock then outstanding shall be entitled to be said in full, out of the net assets of the corporation, the then effective redemption price of such shares (including an amount equal to the accrued dividends on such shares), and no more, before any amount shall be paid or distributed to the holders of shares of the Common Stock. After payment in full to the holders of all shares of the Preferred Stock (of all designations or series) and of any other shares of stock having priority as to assets over the Common Stock, then outstanding, of the amounts to which they are respectively entitled as herein provided, the remaining assets and profits shall be divided among and paid or distributed to the holders of shares of the Common Stock. (3) The corporation, on the sole authority of its Board of Directors, shall have the right at any time or from time to time to redeem and retire all or any part of the Preferred Stock, or all or any part of the shares of any one or more designations or series of the Preferred Stock, upon and by the Payment to the holders of the shares to be redeemed, or upon or by setting aside, as hereinafter provided, for the benefit of such holders, the redemption price or prices of the shares to be redeemed, which -5- redemption price in respect of shares of the 4.40% Cumulative Preferred Stock shall be $107 per share plus accrued dividends to the date of redemption if such date of redemption is subsequent to March 31, 1964; provided that not later than on the thirtieth day prior to the date fixed for such redemption, nor earlier than on the ninetieth day before such date of redemption, notice of the intention of the corporation to redeem such shares, specifying the shares to be redeemed and the date and place of redemption, (a) shall be published in a newspaper of general circula- tion published in the City of Abilene, Texas, and also in a newspaper of general circulation published in the City of Dallas, Texas, and in a newspaper of general circulation published in the City of New York, New York, and (b) shall be deposited in a United States post office or mail box at any place in the United States addressed to each holder of record of the shares to be redeemed, at his address as the same appears upon the records of the corporation; and provided, further, that in mailing such notice, unintentiona1 omissions or errors in names or addresses or other defects in such mailing shall not impair the validity of the notice of, or the proceedings for, such redemption. In every case of the redemption of less than all the outstanding shares of any particular designation or series of the Preferred Stock, the shares of such designation or series to be redeemed shall be chosen by lot in such manner as may be prescribed by resolution of the Board of Directors. The corporation may deposit with a bank or trust company, which shall be named in the notice of redemption, shall be located in Abilene, Texas, or in Dallas, Texas, or in Chicago, Illinois, and shall then have capital, surplus and undivided profits of at least $1,000,000, the aggregate redemption price of the shares to be redeemed, in trust for the payment on or before the redemption date to or upon the order of the holders of such shares, upon surrender of the certificates for such shares. Such deposit in trust may, at the option of the corporation, be upon terms whereby in case the holder of any shares of the Preferred Stock called for redemption shall not, within six years after the date fixed for the redemption of such shares, claim the amount on deposit with any bank or trust company for the payment of the redemption price of said shares, such bank or trust company shall, on demand, when requested by resolution of the Board of Directors of the corporation or its successor, pay to or upon the written order of the corporation or its successor the amount so deposited, and thereupon such -6- bank or trust company shall-be released from any and all further liability with respect to the payment of such redemption price and the holder of said shares shall be entitled to look only to the corporation or its successor for the payment thereof. Upon the giving of notice of redemption and upon the deposit of the redemption price, as aforesaid, or, if no such deposit is made, upon the redemption date (unless the corporation defaults in making payment of the redemption price as set forth in such notice), such holders shall cease to be stockholders with respect to said shares, and from and after the making of said deposit and the giving of said notice, or, if no such deposit is made, after the redemption date (the corporation not having defaulted in making payment of the redemption price as set forth in such notice), said shares shall no longer be transferable on the books of the corporation, and such holders shall have no interest in or claim against the corporation with respect to said shares, but shall be entitled only to receive said moneys on the date fixed for redemption as aforesaid from said bank or trust company, or from the corporation, without interest thereon, upon surrender of the certificates for said shares as aforesaid. All shares of the Preferred Stock which have been redeemed shall be cancelled and retired and shall not be reissued. The term "accrued dividends", as used herein, shall be deemed to mean, in respect of any share of the Preferred Stock as of any given date, the amount of dividends payable on such share, computed, at the annual dividend rate stated in the designation or series of such share, from the date on which dividends thereon became cumulative to and including such given date, less the aggregate amount of all dividends which have been paid or which have been declared and set apart for payment on such share. Accumulations of dividends shall not bear interest. Nothing herein contained shall limit any legal right of the corporation to redeem, purchase or otherwise acquire any shares of the Preferred Stock; provided, however, that the corporation shall not redeem, purchase or otherwise acquire less than all the outstanding shares of the Preferred Stock, if, at the time of such redemption, purchase or other acquisition, dividends payable on the Preferred Stock shall be in default in whole or in part, unless prior to or concurrently with such redemption, purchase or other acquisition, all such defaults shall be cured, or unless such redemption, purchase or other acquisition shall have been ordered, approved or permitted by the Securities and Exchange Commission under the Public Utility Holding Company Act of 1935 or by any successor commission or other regulatory authority of the United States of America then having -7- jurisdiction in the premises. All shares of the Preferred Stock so redeemed, purchased or acquired shall be cancelled and retired and shall not be reissued. (4) So long as any shares of the Preferred Stock shall be outstanding, the corporation shall not, without the consent (given by vote at an annual or special meeting of stockholders) of the record holders of at least two-thirds of the total number of shares of the Preferred Stock then outstanding, voting separately as a class: (A) create, authorize or issue any new stock which, after issuance, would rank prior to the Preferred Stock as to dividends or assets, or create, authorize or issue any security convertible into shares of any such new stock, except for the purpose of providing funds for the redemption of all the Preferred Stock then outstanding, in which case such new stock or security shall not be issued until such redemption shall have been authorized, notice of such redemption given and the aggregate redemption price deposited as provided in paragraph (3) of this Article VI; provided that any such new stock or security, the creation, authorization or issue of which shall have been consented to as herein provided, shall not be issued after the expiration of twelve months following the giving of such consent; or (B) amend, alter, change or repeal any of the express terms of the Preferred Stock then outstanding in a manner substantially prejudicial to the holders thereof; provided that (i) the increase or decrease in the authorized amount of the Preferred Stock or the creation, or increase or decrease in the authorized amount, of any new class of stock ranking on a parity with the Preferred Stock shall not, for the purposes of this subparagraph (B), be deemed to be prejudicial to the holders of the Preferred Stock, and (ii) if any such amendment, alteration, change or repeal would be substantially prejudicial to the holders of shares of one or more, but less than all, of the designations or series of the Preferred Stock at the time outstanding, the consent only of the record holders of at least two-thirds of the total number of outstanding shares of each such designation or series so prejudicially affected shall be required. (5) So long as any shares of the Preferred Stock shall be outstanding, the corporation shall not, without the consent (given by vote at an annual or special meeting of -8- stockholders) of the record holders of a majority of the total number of shares of the Preferred Stock then outstanding, voting separately as a class: (A) merge or consolidate with or into any other corporation or corporations or sell or otherwise dispose of all or substantially all of the assets of the corporation, unless such merger, consolidation, sale or other disposition, or the exchange, issuance or assumption of all securities to be exchanged, issued or assumed in connection with any such merger, consolidation, sale or other disposition, shall have been ordered, approved or permitted by the Securities and Exchange Commission under the Public Utility Holding Company Act of 1935 or by any successor commission or other regulatory authority of the United States of America then having jurisdiction in the premises; provided that the provisions of this subparagraph (A) shall not apply to a purchase or other acquisition by the corporation of franchises or assets of another corporation in any manner which does not involve a corporate merger or consolidation; or (B) issue or assume any unsecured notes, deben- tures or other securities representing unsecured indebtedness (herein called "unsecured obligations"), for purposes other than (i) the refunding of outstanding unsecured indebtedness or unsecured obligations thereto- fore incurred, issued or assumed by the corporation, or (ii) the reacquisition, redemption or other retirement of any indebtedness, if such transaction has been ordered, approved or permitted by the Securities and Exchange Commission under the Public Utility Holding Company Act of 1935 or by any successor commission or other regulatory authority of the United States of America then having jurisdiction in the premises, or (iii) the reacquisition, redemption or other retirement of all outstanding shares of the Preferred Stock or of stock ranking prior to or on a parity with the Preferred Stock, if, immediately after such issue or assumption, the total principal amount of unsecured obligations issued or assumed by the corporation (including any such obligations then to be issued or assumed), computed as hereinafter provided, would exceed an amount equal to 10% of the sum of -9- (a) the total principal amount of all bonds or other securities representing secured indebtedness issued or assumed by the corporation and then to be outstanding, and (b) the aggregate amount of the capital and surplus of the corporation as then to be stated on the books of account of the corporation. In computing, for the purposes of this provision, the total principal amount of unsecured obligations issued or assumed by the corporation and outstanding or to be outstanding as of the date of issue or assumption of any such obligations then to be issued or assumed, there shall be excluded, but in an amount not exceeding in the aggregate 10% of the sum of the amounts specified in clauses (a) and (b) above, the sum of (x) the principal amount of all unsecured obligations the maturity or payment date of which is in excess of ten years from such date, (y) the principal amount of all unsecured obligations which had by their terms an original maturity in excess of ten years but which have become and are due and payable by their terms in ten years or less, but more than three years, from such date, or which are required to be retired, prior to their maturity, whether through a sinking fund or otherwise, in ten years or less, but more than three years, from such date, and (z) the principal amount of all unsecured obligations, the maturity or payment date of which is not later than November 1, 1982, and which had by their terms an original maturity not in excess of ten years, which principal amount is in excess of 10% of the amount specified in clauses (a) and (b) above. And whenever the aggregate principal amount of unsecured obligations outstanding at any such date, determined after making the exclusions as above provided, shall exceed 10% of the sum of the amounts specified in clauses (a) and (b) above, no additional unsecured obligations shall be issued or assumed by the corporation, except for the purposes set forth in items (i), (ii) or (iii) above, until such aggre- gate principal amount of outstanding unsecured obligations shall have been reduced to 10% of the sum of the amounts specified in clauses (a) and (b) above; or -10- (C) issue, sell, or otherwise dispose of any shares of the Preferred Stock (in addition to the initial issue of 60,000 shares of the Preferred Stock), or of any other class of stock ranking on a parity with the Preferred Stock as to dividends or assets, for any purpose other than in exchange for or of effecting the redemption or retirement of not less than an equal number of shares of the Preferred Stock, or of stock ranking prior to or on a parity with the Preferred Stock, then outstanding, unless the gross income of the corporation to be available for the payment of interest for a period of twelve full consecutive calendar months ending within the fifteen calendar months imme- diately preceding the issuance, sale or disposition of such stock, determined in accordance with generally accepted accounting practices [but in any event after deducting all taxes and the greater of (a) the aggregate amount for said period charged by the corporation on its books to income or earned surplus for provision for depreciation of property, or (b) an amount equal to 2.9% (or such other percentage as may upon application by the corporation be approved by the Securities and Exchange Commission, or any successor authority, under the Public Utility Holding Company Act of 1935) of the arithmetical average of the amount of depreciable property of the corporation at the beginning, and the amount thereof at the end, of such 12-month period, in plant accounts of the corporation, with respect to which bonds may at the time be authenticated under any indenture securing first mortgage bonds of the corporation, determined in accordance with generally accepted accounting practices, and provided that amounts included in plant acquisition adjustment account, or accounts of similar purpose, shall not be included in the amount of such property if adequate pro- vision for the amortization of such amounts is made by current charges to income or surplus) shall have been at least one and one-half times the sum of (i) the annual interest charges on all bonds, debentures, notes and other securities representing indebtedness of the corporation, and (ii) the annual dividend requirements on all outstand- ing shares of the Preferred Stock and on all other classes of stock, if any, ranking prior to or on a parity with the Preferred Stock as to dividends or assets, including the shares proposed to be issued; provided that there shall be excluded from the foregoing computation interest charges and dividend requirements on all indebtedness and shares of stock which are to be retired in connection with the issue of such additional shares of the Preferred Stock, or other class of stock ranking prior to or on a parity with the Preferred stock as to dividends or assets; and provided, further, that in any case where such additional shares of the Preferred Stock, or other class of stock ranking on a parity with the Preferred Stock as to dividends -11- or assets, are to be issued in connection with the ac- quisition of additional property, the gross income of the property to be so acquired, computed on the same basis as the gross income of the corporation as above pro- vided, may be included on a pro forma basis in making the foregoing computation; or (D) issue, sell, or otherwise dispose of any shares of the Preferred Stock (in addition to the initial issue of 60,000 shares of the Preferred Stock), or of any other class of stock ranking on a parity with the Preferred Stock as to dividends or assets, unless the aggregate of (i) the capital of the corporation applicable to the Common Stock and (ii) the surplus of the corporation shall be not less than the aggregate amount payable upon the in- voluntary liquidation, dissolution or winding up of the corporation in respect of all shares of the Preferred Stock and all shares of stock, if any, ranking prior to or on a parity with the Preferred Stock as to dividends or assets, which will be outstanding after the issue of the shares proposed to be issued; provided, that if, for the purposes of meeting the requirements of this sub- paragraph (D) it becomes necessary to take into consideration any earned surplus of the corporation, the corporation shall not thereafter pay any dividends on shares of the Common Stock which would result in reducing the corpora- tion's Common Stock Equity (as in paragraph (6) hereinafter defined) to an amount less than the aggregate amount payable upon the involuntary liquidation, dissolution or winding up of the corporation in respect of all shares of the Preferred Stock, and of any stock ranking prior to or on a parity with the Preferred Stock as to dividends or assets, at the time outstanding. No provision contained in this paragraph (5), nor in paragraph (4) of this Article VI, is intended or shall be construed to relieve the corporation from compliance with any applicable statutory provision requiring the vote or consent of the holders of a greater number of the outstanding shares of the Preferred Stock. (6) So long as any shares of the Preferred Stock shall be outstanding, the corporation shall not declare or pay any dividends on its Common Stock, except as follows: (a) if and so long as the Common Stock Equity on the last day of a calendar month ending within sixty days next preceding the date on which a dividend on Common Stock is proposed to be declared is, or as a result of the payment of such dividend would become, -12- less than 20% of total capitalization, the corporation shall not (except as hereinafter provided) declare such dividend in an amount which, together with all other dividends on Common Stock paid within the year ending with and including the date on which such dividend is proposed to be payable, exceeds 50% of the net income of the corporation available for dividends on the Common Stock for the twelve full consecutive calendar months ending within sixty days next preceding the month in which such dividend is proposed to be declared, provided, however, that if dividends (or additional dividends) on Common Stock could have been declared under the foregoing limitation in any previous year or years, but were not declared, then such dividend proposed to be paid may exceed 50% of the above specified net income of the corporation by a total amount equal to the aggregate amount of all dividends on Common Stock that could have been so declared but were not declared; and (b) if and so long as the Common Stock Equity on the last day of a calendar month ending within sixty days next preceding the date on which a dividend on Common Stock is proposed to be declared is, or as a result of the payment of such dividend would become, less than 25% but not less than 20% of total capitalization, the corporation shall not (except as hereinafter provided) declare such dividend in an amount which, together with all other dividends on Common Stock paid within the year ending with and including the date on which such dividend is proposed to be payable, exceeds 75% of the net income of the corporation available for dividends on the Common Stock for the twelve full consecutive calendar months ending within sixty days next preceding the month in which such dividend is proposed to be declared, provided, however, that if dividends (or additional dividends) on Common Stock could have been declared under the foregoing limitation of this paragraph in any previous year or years, but were not declared, then such dividend proposed to be paid may exceed 75% of the above specified net income of the corporation by a total amount equal to the aggregate amount of all dividends on Common Stock that could have been so declared but were not declared; and (c) at any time when the Common Stock Equity is 25% or more of total capitalization, the corporation may not declare dividends on shares of the Common -13- Stock which would reduce the Common Stock Equity below 25% of total capitalization, except to the extent provided or permitted in subparagraphs (a) and (b) above. "Net income of the corporation available for dividends on Common Stock" shall be determined by deducting from the total of operating revenues and other income of the corporation for any given period, all operating expenses for such period (including maintenance, repairs and depreciation, taxes based on income and all other taxes, all proper accruals, interest charges, amortization charges, other proper income deductions and dividends paid or accrued on outstanding shares of stock of the corporation ranking prior to the Common Stock as to dividends, for such period), all as determined in accordance with such system of accounts as may be prescribed by regulatory authorities having jurisdiction in the premises or, in the absence of any such system of accounts, in accordance with generally accepted accounting practices. For the purposes of this paragraph (6) and of subpara- graph (D) of paragraph (5) hereof: The term "Common Stock Equity" shall mean the sum of (a) the aggregate par value of, or stated capital represented by, the outstanding shares (other than shares owned by the corporation) of stock of the corporation ranking junior to the Preferred Stock as to dividends or assets, (b) the premium on such junior ranking stock, and (c) the surplus (including earned surplus, capital or paid-in surplus and surplus invested in plant) of the corporation, less, unless the amounts or items are being amortized or are being provided for by reserves, (1) any amounts recorded on the books of the corporation for utility plant and other plant in excess of the original cost thereof, (2) unamortized debt discount and expense, capital stock discount and expense and any other intangible items set forth on the asset side of the balance sheet as a result of accounting convention, (3) the excess, if any, of the aggregate amount payable on involuntary liquidation, dissolution or winding up of the affairs of the corporation upon all outstanding preferred stock of the corporation over the aggregate par or stated value of such preferred stock and any premiums thereon, (4) the excess, if any, for the period beginning January 1, 1954, and ending December 31, 1976, of an amount equal to 15% of the gross operating revenues derived by the corporation from the operation of its properties for the period (excluding therefrom non-operating income and revenues derived directly from properties leased to the corporation), after deducting from such revenues the aggregate cost of electric energy and gas purchased for exchange or resale, over the aggregate amount charged or provided by the cor- poration on its books for maintenance, repairs and depre- ciation for such period, and (5) the excess, if any, for the period beginning January 1, 1977, to the end of a month ending within ninety days next preceding the date as of which Common Stock Equity is being determined, of an amount equal to 2.9% annually (or such other percentage as may upon application by the corporation be approved by the Securities and Exchange Commission, or any successor authority, under the Public Utility Holding Company Act of 1935) of the arithmetical average of the amount of depreciable property of the corporation at the beginning and the amount thereof at the end, of each calendar year and portion thereof contained in such period, in plant accounts of the corporation, with respect to which bonds may at the time be authenticated under any indenture securing first mortgage bonds of the corporation, determined in accordance with generally accepted accounting practices (excluding amounts included in plant acquisition adjustment account, or accounts of similar purposes, if adequate provision for the amortization of such amounts is made by current charges to income or surplus), over the aggregate amount charged or provided by the corporation on its books as charges for depreciation, retirements, renewals and replacements and/or amortization for such period. For the purposes of this paragraph (6): (i) The term "total capitalization" of the corporation shall mean the aggregate of (a) the principal amount of all outstanding bonds, debentures, notes and other securities representing indebtedness (whether secured or unsecured) of the corporation maturing more than twelve months after the date as of which total capitalization is being determined, and (b) the par value of, or stated capital represented by, the outstanding shares of the capital stock of all classes of the corporation, all premiums in respect of such stock, as carried on the books of the corporation, and the amount of all surplus accounts of the corporation, after deducting from such aggregate any amounts required to be deducted, in the determination of Common Stock Equity, pursuant to the provisions of clauses (1) and (2) of the foregoing definition of "Common Stock Equity." (ii) The term "dividends on Common Stock" shall include dividends on Common Stock (other than dividends payable only in shares of Common Stock), distributions on, and purchases or other acquisitions for value of, any Common Stock of the corporation or other stock, if any, ranking -14- -15- junior to the Preferred Stock as to dividends or assets. (7) (a) No holder of shares of the Preferred Stock shall be entitled to vote, at any meeting of stockholders of the corporation, for the election of directors or in respect of any other matter, except as expressly provided in paragraph (4) or (5) of this Article VI or in this paragraph (7) or as may be required by law. In such excepted cases, each record holder of shares of the Preferred Stock shall have one vote for each share of the Preferred Stock held by him. Each record holder of shares of Common Stock shall, at all meetings of stockholders of the corporation, have one vote for each share of Common Stock held by him, except as otherwise provided in this paragraph (7). (b) If and when dividends payable on the Preferred Stock at any time outstanding shall be in default in an amount equal to four full quarter-yearly dividends or more per share, and thereafter until all dividends on such Preferred Stock in default shall have been paid, the record holders of shares of the Preferred Stock, voting separately as a class, shall be entitled, at each meeting of stockholders at which directors are elected, to elect the smallest number of directors necessary to constitute a majority of the full Board of Directors of the corporation, and, except as provided in the next following paragraph (c), the holders of the Common Stock, voting separately as a class, shall be entitled to elect the remaining directors of the corporation. The terms of office, as directors, of all persons who may be directors of the corporation at the time shall terminate upon the election of a majority of the Board of Directors by the holders of the Preferred Stock, except that if the holders of the Common Stock shall not have elected the remaining directors of the corporation, then, and only in that event, the directors of the corporation in office just prior to the election of a majority of the Board of Directors by the holders of the Preferred Stock shall elect the remaining directors of the corporation. Thereafter, while such default continues and the majority of the Board of Directors is being elected by the holders of the Preferred Stock, the remaining directors, whether elected by directors as aforesaid, or, whether originally or later elected by holders of the Common Stock, shall continue in office until their successors are elected by holders of the Common Stock and shall qualify. (c) If and when all dividends then in default on the Preferred Stock then outstanding shall be paid (such -16- dividends to be declared and paid, out of any funds legally available therefor, as soon as reasonably practicable), the holders of shares of the Preferred Stock shall be divested of any special right with respect to the election of directors, and the voting power of the holders of the Preferred Stock and the holders of the Common Stock shall revert to the status existing before the first dividend payment date on which dividends on the Preferred Stock were not paid in full, but always subject to the same provisions for vesting such special rights in the record holders of shares of the Preferred Stock in case of further like defaults in the payment of dividends thereon as described in the foregoing paragraph (b). Upon termination of any such special voting right upon payment of all accumulated and unpaid dividends on the Preferred Stock, the terms of office of all persons who may have been elected directors of the corporation by vote of the holders of the Preferred Stock as a class, pursuant to such special voting right, shall forthwith terminate, and the resulting vacancies shall be filled by the vote of a majority of the remaining directors. Dividends shall be deemed to have been paid, as that term is used in this paragraph (c), whenever such dividends shall have been declared and paid, or declared and provision made for the payment thereof, or whenever there shall be sufficient surplus or net profits of the corporation legally available for the payment thereof which shall have accrued since the date of the default giving rise to such special voting right. (d) In case of any vacancy in the office of a director occurring among the directors elected by the holders of the Preferred Stock, voting separately as a class, the remaining directors elected by the holders of the Preferred Stock, by affirmative vote of a majority thereof, or the remaining director so elected if there be but one, may elect a successor or successors to hold office for the unexpired term or terms of the director or directors whose place or places shall be vacant. Likewise, in case of any vacancy in the office of a director occurring among the directors not elected by the holders of the Preferred Stock, the remaining directors not elected by the holders of the Preferred Stock, by affirmative vote of a majority thereof, or the remaining director so elected if there be but one, may elect a successor or successors to hold office for the unexpired term or terms of the director or directors whose place or places shall be vacant. (e) Whenever the right shall have accrued to the record holders of the Preferred Stock to elect directors, voting separately as a class, it shall be the duty of the -17- President, a Vice-President or the Secretary of the corporation forthwith to call and cause notice to be given to the stockholders entitled to vote of a meeting to be held at such time as the officers of the corporation may fix, not less than forty-five nor more than sixty days after the accrual of such right, for the purpose of electing directors. The notice so given shall be mailed to each record holder of shares of the Preferred Stock at his last known address appearing on the records of the corporation and shall set forth, among other things, (i) that by reason of the fact that dividends payable on the Preferred Stock are in default in an amount equal to four full quarter- yearly dividends or more per share, the record holders of the Preferred Stock, voting separately as a class, have the right to elect the smallest number of directors necessary to constitute a majority of the full Board of Directors of the corporation, (ii) that any record holder of the Preferred Stock has the right, at any reasonable time, to inspect, and make copies of, the list or lists of record holders of the Preferred Stock maintained at the principal office of the corporation or at the office of any Transfer Agent of the Preferred Stock, and (iii) either the entirety of this paragraph or the substance thereof with respect to the number of shares of the Preferred Stock required to be represented at any meeting, or adjournment thereof, called for the election of directors of the corporation. At the first meeting of stockholders held for the purpose of electing directors during such time as the holders of the Preferred Stock shall have the special right, voting separately as a class, to elect directors, the presence in person or by proxy of the record holders of not less than a majority of the outstanding shares of Common Stock shall be required to constitute a quorum of such class for the election of directors, and the presence in person or by proxy of the record holders of not less than a majority of the out- standing shares of Preferred Stock shall be required to constitute a quorum of such class for the election of directors; provided, however, that in the absence of a quorum of the holders of Preferred Stock, no election of directors shall he held, but the holders of a majority of the Preferred Stock present in person or by proxy shall have power to adjourn the election of the directors to a date not less than fifteen nor more than fifty days from the giving of the notice of such adjourned meeting hereinafter provided for; and provided, further, that at such adjourned meeting, the presence in person or by proxy of the record holders of not less than 35% of the outstanding shares of Preferred Stock shall be required to constitute a quorum of such class for the election of directors. In -18- the event such first meeting of stockholders shall be so adjourned, it shall be the duty of the President, a Vice- President or the Secretary of the corporation, within ten days from the date on which such first meeting shall have been adjourned, to cause notice of such adjourned meeting to be given to the stockholders entitled to vote thereat, such adjourned meeting to be held not less than fifteen days nor more than fifty days from the giving of such second notice. Such second notice shall be given in the form and manner hereinabove provided for with respect to the notice required to be given of such first meeting of stockholders, and shall further set forth that a quorum was not present at such first meeting and that the record holders of not less than 35% of the outstanding shares of Preferred Stock shall be required to constitute a quorum of such class for the election of directors at such adjourned meeting. If the requisite quorum of the record holders of the Preferred Stock shall not be present at said adjourned meeting, then the directors of the corporation then in office shall remain in office until the next annual meeting of stockholders of the corporation, or special meeting in lieu thereof, and until their successors shall have been elected and shall qualify. Neither such first meeting nor such adjourned meeting shall be held on a date within sixty days of the date of the next annual meeting of stockholders of the corporation or special meeting in lieu thereof. At each annual meeting of stockholders of the corporation, or special meeting in lieu thereof, held during such time as the record holders of the Preferred Stock, voting separately as a class, shall have the right to elect a majority of the Board of Directors, the foregoing provisions of this paragraph (e) shall govern each annual meeting of stockholders, or special meeting in lieu thereof, as if said annual meeting or special meeting were the first meeting of stockholders held for the purpose of electing directors after the right of the record holders of the Preferred Stock, voting separately as a class, to elect a majority of the Board of Directors, should have accrued, with the exception that if, at any adjourned annual meeting or special meeting in lieu thereof, the record holders of not less than 35% of the outstanding shares of Preferred Stock are not present in person or by proxy, all the directors shall be elected by a vote of the record holders of not less than a majority of the shares of Common Stock of the corporation present or represented at the meeting. (f) In consideration of the issue, sale or delivery by the corporation, and the purchase or other acquisition by the holders thereof, of shares of the capital stock (both -19- preferred and common) of the corporation, each and every present and future holder of shares of the capital stock (both preferred and common) of the corporation shall be conclusively deemed, by purchasing, acquiring or holding such shares, to have expressly consented to all and singular the terms and provisions of this paragraph (7) and to have agreed that the voting rights of such holder, and the restrictions and qualifications thereof, shall be as set forth in this paragraph (7). (8) No share of stock or evidence of indebtedness shall be deemed to be "outstanding", as that term is used in this Article VI, if, prior to or concurrently with the event in reference to which a determination as to the amount thereof outstanding is to be made, the requisite funds for the redemption, payment or other retirement thereof shall be deposi- ted in trust for that purpose and, in the case of redemption, the requisite notice for the redemption thereof shall be given or the depositary of such funds shall be irrevocably authorized and directed to give or complete such notice of redemption. (9) No holder of shares of stock of any class of the corporation shall be entitled, as a matter of right, to subscribe for, purchase or receive any shares of the stock of any class of the corporation, or any rights or options of the corporation which it may issue or sell, whether out of the number of shares now authorized or hereafter authorized. Nor shall any holder of shares of stock, of any class, of the corporation be entitled, as a matter of right, to subscribe for, purchase or receive any bonds, debentures or other obligations which the corporation may issue or sell, which shall be convertible into or exchangeable for stock of any class, or to which shall be attached or appertain any warrant or warrants (or other instrument or instruments) which shall confer upon the holder or owner the right to subscribe for or purchase from the corporation any shares of its capital stock of any class; and all such additional issues of stock, rights, options, or of bonds, debentures or other obligations convertible into or exchangeable for stock, or to which such warrants shall be attached or appertain, may be issued and disposed of as determined by the Board of Directors to such persons (whether stockholders or not), at such times, for such consideration and upon such terms, permitted by the laws of the State of Texas, as the Board of Directors in its absolute discretion may deem advisable. (10) The corporation reserves the right to increase or decrease its authorized capital stock, or any class or classes thereof or any designation or series of any such class, or to reclassify the same, and to amend, alter, -20- change or repeal any provision contained in the Charter (as amended) of the corporation or in any future amendment to the Charter as then in effect, in the manner now or hereafter prescribed by law, but subject to such conditions and limitations as are hereinabove prescribed; and all rights granted to or conferred upon stockholders in the Charter (as amended) of the corporation or any future amendment thereto, are granted or conferred subject to this reservation. (11) Neither a consolidation or merger of the corporation with or into any other corporation, nor a merger of any other corporation into the corporation, nor the purchase or other acquisition, redemption or other retirement by the corporation of all or any part of the outstanding shares of its preferred stock of any class, shall be deemed a distribution of assets, or a liquidation, dissolution or winding up, of the corporation within the meaning of any of the provisions of the Charter (as amended) of the corporation, as then in effect.

The shares of said series shall be subject to redemption, in whole at any time or in part from time to time, upon the notice and in the manner and with the effect provided in the Restated Articles of Incorporation, as amended, of the corpo- ration; and the redemption prices applicable to each of the shares of said series shall be the sum of $100.00, together with all unpaid dividends thereon accrued to the date of redemption, and, in addition, a premium of $10.16 per share if redeemed prior to June 1, 1988; $6.77 per share if redeemed on or after June 1, 1988, and prior to June 1, 1993; $3.39 per share if redeemed on or after June 1, 1993, and prior to June 1, 1998; and no premium if redeemed on or after June 1, 1998; provided, that none of the shares of said series may be redeemed, prior to June 1, 1988, if such redemption is for the purpose of refunding or is in anticipa- tion of the refunding of said shares through the use, directly or indirectly, of funds obtained by the corporation through the issuance of any shares of Preferred Stock or any other stock ranking prior to or on a parity with the Preferred Stock, or through the incurrence of debt by the corporation, at a dividend or interest cost, as the case may be, less than 10.236% per annum. 6. In the event of the voluntary liquidation, dissolu- tion or winding up of the corporation, the amount which the holders of shares of the 10.16% Preferred Stock then outstanding shall be entitled to be paid in full, out of the net assets of the corporation and before any amount shall be paid or distributed to the holders of shares of the Common stock, shall be the then effective redemption price of such shares of Preferred Stock as provided in paragraph 5 above (including an amount equal to the accrued dividends on such shares), and no more. 7. The shares of said series shall be subject to the terms, provisions and restrictions set forth in the Restated Articles of Incorporation, as amended, of the corporation with respect to the shares of Preferred Stock of the corporation, shall be of equal rank with and, excepting only as to the rate of dividend payable thereon, the voluntary liquidation prices and the redemption prices thereof and the terms and conditions of -2- redemption applicable thereto and shall confer rights equal to the rights conferred by all other shares of Preferred Stock of the corporation. 8. During each 12 month period ending May 31 in each year, beginning in 1989, as and for a sinking fund for the shares of said series the corporation shall, subject to the restrictions contained in this resolution, redeem and retire 7,500 shares of said series (being 3% of the number of shares of said series originally issued) at the sinking fund redemption price of $100 per share plus accrued dividends to the date of redemption (such required redemptions being hereinafter referred to as the "sinking fund requirement"). The sinking fund requirement shall be cumula- tive so that if the corporation shall fail to satisfy in full the sinking fund requirement in any such 12 month period, the amount of the deficiency shall be added to the sinking fund requirement for succeeding 12 month periods until such deficiency shall be made good. Such deficiency shall be made good as soon as practi- cable. In the event that the corporation is in arrears in the sinking fund requirement for any such 12 month period or periods, and so long as the corporation shall remain in arrears in such requirement, the corporation may not purchase, redeem or pay dividends on any of its stock ranking junior to the shares of said series. 9. The corporation may satisfy the whole or any part of the sinking fund requirement for any such 12 month period by cancelling and retiring, prior to the end of such 12 month period, shares of said series purchased by the corporation or shares of said series redeemed by the corporation otherwise than pursuant to paragraph 8 of this resolution. 10. The corporation may redeem through the sinking fund during any such 12 month period not more than 7,500 additional shares of said series. Any redemption of such additional shares so redeemed will not reduce the sinking fund requirement in any subsequent 12 month period, and the right of the corporation to apply such additional shares to the sinking fund requirement will not be cumulative. 11. All shares of said series redeemed or purchased, including those applied to meet the sinking fund requirement, shall be cancelled and retired and shall become authorized but unissued shares of Preferred Stock but may not be reissued as shares of said series. 12. No shares of said series shall be redeemed to satisfy the sinking fund requirement unless, at the date such shares are called for redemption, full dividends on all shares of -3- the Preferred Stock of the corporation for all prior periods shall have been paid or declared and set apart for payment. Nothing contained in this resolution shall be deemed to require the corporation to redeem or purchase shares of said series at a time when it may not legally do so."
