           1. Number; Series. The Preferred Stock may be issued in one or more
series, from time to time, with each such series to have such designation,
powers, preferences and relative, participating, optional or other special
rights and qualifications, limitations or restrictions thereof, as shall be
stated and expressed in an amendment to these Articles of Incorporation
providing for the issue of such series. The board of directors of the
corporation is hereby expressly vested with authority to amend the Articles of
Incorporation, without shareholder action or approval, to: (a) create one or
more series of the Preferred Stock, fix the number of shares of each such series
(within the total number of authorized shares of the Preferred Stock available
for designation as a part of such series), and designate and determine, in whole
or part, the preferences, limitations, and relative rights of each series of the
Preferred Stock; (b) alter or revoke the preferences, limitations and relative
rights granted to or imposed upon any wholly unissued series of the Preferred
Stock; or (c) increase or decrease the number of shares constituting any series
of the Preferred Stock (the number of shares of which was originally fixed by
the board of directors) either before or after the issuance of shares of the
series, provided that the number may not be decreased below the number of shares
of such series then outstanding, or increased above the total number of
authorized shares of the Preferred Stock available for designation as a part of
such series. 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:

                     (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;

                     (vii) The rights of the shares of the series in the event
of voluntary or involuntary liquidation, dissolution or upon distribution of
assets of the corporation;

                                       3

<PAGE>   4
                     (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 the 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 the Preferred Stock, the board of directors
may, subject to the provisions of the resolution or resolutions creating the
series of the Preferred Stock, declare and pay dividends on the Common Stock as
provided in paragraph B.1. of this Article III, and the holders of shares of the
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 the
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
Stock shall be entitled to share in all assets of the corporation remaining as
provided in paragraph B.2. of this Article III. If, upon such liquidation,
dissolution or winding up, the assets of the corporation distributable as
aforesaid among the holders of the 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 A.3.

           4. Voting. Except as otherwise provided by an amendment to the
Articles of Incorporation creating any series of the 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 III.

           5. Preemptive Rights. Except as otherwise provided by an amendment to
the Articles of Incorporation providing for the issuance of any series of the
Preferred Stock, no holder of shares of the Preferred Stock 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 the Preferred
Stock, and subject to any other provisions of the Articles of Incorporation,
holders of the Common Stock shall be entitled to receive such dividends and
other distributions in cash, stock or property of the 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 the Preferred Stock of all amounts required in
accordance with paragraph A.3. of this Article III, the remaining assets and
funds of the corporation shall be divided among and paid to the holders of the
Common Stock.

           3.        Voting.

                     (a) At every  meeting of the  shareholders  of the  
corporation, every holder of the Common Stock shall be entitled to one vote in
person or by proxy for each share of such Common Stock standing in his name on
the stock transfer records of the corporation.

                     (b) No shareholder shall have the right to cumulate votes
in the election of directors.

           4. Preemptive Rights. No holder of shares of the Common 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.


                             ARTICLE IV - DIRECTORS

           The number of directors of the corporation shall be as determined by
resolution of the board of directors, but shall not be less than three (3) nor
more than nine (9).

           The personal liability of any director to the corporation or to its
shareholders for monetary damages for any action taken or any failure to take
any action, as a director, is hereby eliminated to the fullest extent permitted
by Utah laws. In the event the applicable Utah law or this Article IV is
repealed or amended to decrease or limit in any manner the protection or rights
available to directors hereunder, such repeal or amendment shall not be
retroactively applied in determining the personal liability of a director
pursuant to this Article IV prior to the enactment of such amendment.

                     ARTICLE V - REGISTERED OFFICE AND AGENT

           The street address of the corporation's registered office and the
