Without limiting the foregoing, the authority of the board of directors with respect to each such series shall include, but not be limited to, the determination or fixing of the following:

2

(i)The distinctive designation and number of shares comprising such series, which number may (except where otherwise provided by the board of directors in creating such series) be increased or decreased (but not below the number of shares then outstanding) from time to time by like action of the board of directors;

(ii)The dividend rate of such series, the conditions and times upon which such dividends shall be payable, the relation which such dividends shall bear to the dividends payable on any other class or classes of stock or series thereof, or on the other series of the same class, and whether dividends shall be cumulative or noncumulative;

(iii)The conditions upon which the shares of such series shall be subject to redemption by the corporation and the times, prices and other terms and provisions upon which the shares of the series may be redeemed;

(iv)Whether or not the shares of the series shall be subject to the operation of retirement or sinking fund provisions to be applied to the purchase or redemption of such shares and, if such retirement or sinking fund be established, the annual amount thereof and the terms and provisions relative to the operation thereof;

(v)Whether or not the shares of the series shall be convertible into or exchangeable for shares of any other class or classes, with or without par value, or of any other series of the same class and, if provision is made for conversion or exchange, the times, prices, rates, adjustments and other terms and conditions of such conversion or exchange;

(vi)Whether or not the shares of the series shall have voting rights, in addition to the voting rights provided by law, and, if so, subject to the limitations hereinafter set forth, the terms of such voting rights;

(viii)Any other powers, preferences and relative, participating, optional or other special rights, and qualifications, limitations or restrictions thereof, of the shares of such series, as the board of directors may deem advisable.

2.Dividends. The holders of the shares of Preferred Stock of each series shall be entitled to receive, when and as declared by the board of directors, out of the funds legally available for the payment of dividends, dividends at the rate fixed by the board of directors for such series for the current period and, if cumulative, for all prior periods for which such dividends are cumulative.

Whenever, at any time, dividends on the then outstanding Preferred Stock as may be required with respect to any series outstanding shall have been paid or declared and set apart for payment on the then outstanding Preferred Stock, and after complying with respect to any retirement or sinking fund or funds for all applicable series of Preferred Stock, the board of directors may, subject to the provisions of the resolution or resolutions creating the series of Preferred Stock, declare and pay dividends on the Common Stock as provided in paragraph B.l. of this Article IV, and the holders of shares of Preferred Stock shall not be entitled to share therein, except as otherwise provided in the amendment creating any series.

3.Liquidation; Dissolution. The holders of the Preferred Stock of each series shall be entitled upon liquidation or dissolution of the corporation to such preferences as are provided in the amendment creating such series of Preferred Stock, and no more, before any distribution of the assets of the corporation shall be made to the holders of shares of the Common Stock. Whenever the holders of shares of the Preferred Stock shall have been paid the full amounts to which they shall be entitled, the holders of shares of the Common

3

Stock shall be entitled to share in all assets of the corporation remaining as provided in paragraph B.2. of this Article IV. If, upon such liquidation, dissolution or winding up, the assets of the corporation distributable as aforesaid among the holders of Preferred Stock of all series shall be insufficient to permit full payment to them of said preferential amounts, then such assets shall be distributed ratably among such holders in proportion to the respective total amounts which they shall be entitled to receive as provided in this paragraph 3.

4.Voting. Except as otherwise provided by an amendment to the Articles of Incorporation creating any series of Preferred Stock or by the general corporation law of Utah, the

Common Stock issued and outstanding shall have and possess the exclusive power to vote for the election of directors and for all other purposes as provided in paragraph B.3. of this Article IV.

5.Preemptive Rights. Except as may be provided in the amendment adopted by the board of directors providing for the issue of any series of Preferred Stock, no holder of shares of the Preferred Stock of the corporation shall, as such holder, be entitled as of right to subscribe for, purchase or receive any part of any new or additional issue of stock of any class, whether now or hereafter authorized, or of bonds, debentures or other securities convertible into or exchangeable for stock, but all such additional shares of stock of any class, or bonds, debentures or other securities convertible into or exchangeable for stock, may be issued and disposed of by the board of directors on such terms and for such consideration, so far as may be permitted by law, and to such persons, as the board of directors in its absolute discretion may deem advisable.

B. COMMON STOCK

1.Dividends. Subject to the rights of the holders of Preferred Stock, and subject to any other provisions of the Articles of Incorporation, holders of Common Stock shall be entitled to receive such dividends and other distributions in cash, stock or property of this corporation as may be declared thereon by the board of directors from time to time out of assets or funds of the corporation legally available therefor.

2.Liquidation; Dissolution. In the event of any liquidation, dissolution or winding up of the affairs of the corporation, whether voluntary or involuntary, after payment or provision for payment of the debts and other liabilities of the corporation and after payment or provision for payment to the holders of each series of Preferred Stock of all amounts required in accordance with paragraph A.3. of this Article IV, the remaining assets and funds of the corporation shall be divided among and paid to the holders of Common Stock.

DIRECTORS

The board of directors shall consist of such number of members, which number shall not be less than three and not more than eleven as may be determined and established from time to time by the board of directors and shall be divided into three classes, as nearly equal in size as possible.
