            express  grant of authority to the board of directors to amend these
            Articles  of   Incorporation   to  fix  the   designation,   powers,
            preferences and relative,  participating,  optional or other special
            rights, and qualifications,  limitations or restrictions thereof, of
            each share of Preferred  Stock which are not fixed by these Articles
            of Incorporation, are as follows:

            A.    PREFERRED STOCK

                  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  Preferred  Stock,  fix the number of
            shares of each such series  (within the total  number of  authorized
            shares of 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
            Preferred Stock;  (b) alter or revoke the  preferences,  limitations
            and relative  rights granted to or imposed upon any wholly  unissued
            series of Preferred Stock; or (c) increase or decrease the number of
            shares  constituting  any series of  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;

                                      2





                        (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;

                        (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

                                      3





            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.1. 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  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.


                                      4





                  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 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 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.

                  3.    Voting.

                        (a) At every meeting of the shareholders every holder of
            Common Stock shall be entitled to one vote in person or by proxy for
            each share of such 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.


                                      5





            

                  4. Preemptive  Rights.  No holder of shares of 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.

      B.    Article  VI  of  the  Articles of Incorporation is hereby amended to
            read as follows:

                                  ARTICLE VI
                                   DIRECTORS

                  The  board  of  directors  shall  consist  of such  number  of
            members, which number shall not be less than three and not more than
            nine 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.  No increase in the maximum number
            of members  shall be made  except upon the  affirmative  vote of not
            less  than  two-thirds  of  the  outstanding  capital  stock  of the
            corporation entitled to vote thereon. The initial terms of directors
            first elected or reelected by the shareholders after the adoption of
            this amendment and revision of the Articles of  Incorporation  shall
            be for the following terms of office:

                         Class A Directors - One Year

                         Class B Directors - Two Years

                         Class C Directors - Three Years

                  Upon the  expiration  of the initial term  specified  for each
            class of directors, their successors shall be elected for three-year
            terms or until such time as their  successors  shall be elected  and
            qualified, with one class of directors to be elected each year.

                                      6





                  Vacancies  on the board of  directors,  whether  the result of
            removal (with or without  cause),  death,  resignation or otherwise,
            shall be filled by  majority  vote of the  remaining  members of the
            board of  directors,  regardless of whether such  remaining  members
            constitute a quorum.

                  The corporation  shall nominate persons to serve as members of
            the board of directors upon the expiration of the term of each class
            of  directors,   which   nominations   shall  be  submitted  to  the
            shareholders at the annual meeting of shareholders for approval. Any
            nominations  for  election  to  the  board  of  directors  shall  be
            received,  with respect to any annual meeting of  shareholders,  not
            later  than  the  date  specified  by the  board  of  directors  for
            submission of such nominations. Failure to submit timely nominations
            shall  prevent  consideration  of the  nominations  at  such  annual
            shareholders' meetings.

                  Directors of the  corporation  may be removed "for cause" only
            upon  the  affirmative  vote of the  holders  of a  majority  of the
            outstanding  capital stock entitled to vote thereon.  A director may
            be  removed  for cause only  after a finding  that (i) the  director
            engaged  in  fraudulent  or  dishonest  conduct  or  gross  abuse of
            authority or discretion,  with respect to the  corporation  and (ii)
            removal is in the best  interests of the  corporation.  Directors of
            the  corporation may be removed for any reason other than cause only
            upon the affirmative vote of the holders of not less than two-thirds
            of the outstanding capital stock of the corporation entitled to vote
            thereon.


                                     III.

      The number of shares of the capital stock of the  Corporation  outstanding
and entitled to be cast on the foregoing  Amendments by the  shareholders of the
Corporation was 7,239,681 shares of common stock (the "Common Stock").  No other
class of shares was issued and outstanding.

                                      IV.

      The  number of shares  of the  Common  Stock  voted for the  Amendment  to
Article IV was 2,962,020  shares;  977,908 shares of the Common Stock were voted
against such  Amendment.  The number of shares of the Common Stock voted for the
Amendment to Article VI was 3,161,677 shares; 970,848 shares of the Common Stock
