                  Corporation available for distribution to its stockholders
                  after all amounts to which the holders of Preferred Stock are
                  entitled have been paid or set aside in cash for payment.

                  holder of Common Stock shall be entitled to one vote for each
                  share thereof held.

                   (B)      PREFERRED STOCK

                  of the Board of Directors of the Corporation providing for its
                  issue. All shares of any one series of Preferred Stock will be
                  identical, but shares of different series of Preferred Stock
                  need not be identical or rank equally except insofar as
                  provided by law or herein.

                                     (2) Creation of Series. The Board of
                  Directors will have authority by resolution to cause to be

                  issuance of any shares of the series to which such resolution
                  relates:

                           of Directors;

                           Corporation;

                                             (g) Whether or not the shares of

                           series in any respect, or restricting the payment of
                           dividends on or the making of other distributions in
                           respect of shares of any other series or class
                           ranking junior to the shares of the series as to

                                             (h) Whether the series will have
                           voting rights, in addition to any voting rights
                           provided by law, and, if so, the terms of such voting
                           rights; and

                                       3


                                             (i) Any other preferences,
                           qualifications, privileges, options and other
                           relative or special rights and limitations of that
                           series.

                                     (3) Dividends. Holders of Preferred Stock
                  shall be entitled to receive, when and as declared by the
                  Board of Directors, out of funds legally available for the
                  payment thereof, dividends at the rates fixed by the Board of
                  Directors for the respective series, and no more, before any
                  dividends shall be declared and paid, or set apart for
                  payment, on Common Stock with respect to the same dividend
                  period.

                                     (4) Preference on Liquidation. In the event
                  of the voluntary or involuntary liquidation, dissolution or
                  winding up of the Corporation, holders of each series of
                  Preferred Stock will be entitled to receive the amount fixed
                  for such series plus, in the case of any series on which
                  dividends will have been determined by the Board of Directors
                  to be cumulative, an amount equal to all dividends accumulated
                  and unpaid thereon to the date of final distribution whether
                  or not earned or declared before any distribution shall be
                  paid, or set aside for payment, to holders of Common Stock. If
                  the assets of the Corporation are not sufficient to pay such
                  amounts in full, holders of all shares of Preferred Stock will
                  participate in the distribution of assets ratably in
                  proportion to the full amounts to which they are entitled or
                  in such order or priority, if any, as will have been fixed in
                  the resolution or resolutions providing for the issue of the
                  series of Preferred Stock. Neither the merger nor
                  consolidation of the Corporation into or with any other
                  corporation, nor a sale, transfer or lease of all or part of
                  its assets, will be deemed a liquidation, dissolution or
                  winding up of the Corporation within the meaning of this
                  paragraph except to the extent specifically provided for
                  herein.

                                     (5) Redemption. The Corporation, at the
                  option of the Board of Directors, may redeem all or part of
                  the shares of any series of Preferred Stock on the terms and
                  conditions fixed for such series.

                                     (6) Voting Rights. Except as otherwise
                  required by law or as otherwise provided herein, the holders
                  of Preferred Stock shall have no voting rights and shall not
                  be entitled to any notice of meeting of stockholders.

                                    ARTICLE V

                  Prohibitions and Restrictions Imposed by Indebtedness. To the
extent that any action required to be taken by the Corporation under this
Amended and Restated Articles of Incorporation shall be prohibited or restricted
by the terms of any contract or instrument to which the Corporation is a party
in respect of the incurrence of indebtedness, such Corporation's actions shall
be delayed until such time as such prohibition or restriction is no longer in
force.

                                   ARTICLE VI

                                       4


                  Bylaws. In furtherance and not in limitation of the powers
conferred by statute, the By-Laws of the Corporation, except as otherwise
specifically provided therein, may be adopted, amended or repealed by the
affirmative vote of the majority of the Board of Directors of the Corporation or
by the vote of the holders of record of a majority of the outstanding voting
stock of the Corporation.

                                   ARTICLE VII

                  Consent of Stockholders in Lieu of Meeting. Any action
required to be taken, or which may be taken, at any meeting of stockholders may
be taken without a meeting, without prior notice and without a vote, if a
consent or consents in writing, setting forth the action so taken, shall be
signed by the holders of shares of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares of stock entitled to vote thereon were present
and voted and shall be delivered to the Corporation by delivery to its statutory
place of business in the State of Arizona, its principal place of business, or
an officer or agent of the Corporation having custody of the book in which
proceedings of meetings of stockholders are recorded; provided that prompt
notice of the taking of corporate action without a meeting by less than
unanimous written consent shall be given to those stockholders who have not
consented in writing.

                                  ARTICLE VIIII
