                                   ARTICLE III

                               AUTHORIZED CAPITAL

         The total  number of shares of all  classes of capital  stock which the
corporation shall have the authority to issue is  One-Hundred-Fifty-One  Million
(151,000,000) shares consisting of:

                  (i)  One-Hundred-Fifty  million (150,000,000) shares of Common
         Stock, par value $0.001 per share  (hereinafter  referred to as "Common
         Stock"); and

                  (ii) One million  (1,000,000)  shares of Preferred  Stock, par
         value $.001 per share (hereinafter referred to as "Preferred Stock").

         The  Preferred  Stock  may be  issued  from time to time in one or more
series,  each of such series to have such voting powers,  full or limited, or no
voting powers, and such designations,  preferences and relative,  participating,
optional  or  other  special   rights,   and   qualifications,   limitations  or
restrictions  thereof,  as shall be stated  and  expressed  in a  resolution  or
resolutions  providing  for the  issue of such  series  adopted  by the Board of
Directors.  As so provided in such  resolution or resolutions  and as and to the
extent  permitted by law, the shares of any series of the Preferred Stock may be
made subject to redemption,  or convertible  into or exchangeable  for shares of
any other class or series,  by the corporation at its option or at the option of
the holders or upon the happening of a specified event.

         Shares of any  series of  Preferred  Stock  which  shall be issued  and
thereafter acquired by the corporation through purchase, redemption, conversion,
exchange or  otherwise,  shall return to the status of  authorized  but unissued
Preferred Stock of the same series unless  otherwise  provided in the resolution
or  resolutions  of the Board of  Directors.  Unless  otherwise  provided in the
resolution or resolutions  of the Board of Directors  providing for the issuance
thereof,  the  number of  authorized  shares of stock of any such  series may be
increased  or  decreased  (but not below  the  number  of  shares  thereof  then
outstanding) by resolution or resolutions of the Board of Directors. In case the
number of  outstanding  shares of any such  series of  Preferred  Stock shall be
decreased,  the  shares  representing  such  decrease  shall,  unless  otherwise
provided in the resolution or  resolutions  of the Board of Directors  providing
for the issuance thereof, resume the status of authorized but unissued Preferred
Stock, undesignated as to series.

         No holder of Common Stock or any series of  Preferred  Stock shall have
the right to cumulate  votes in the election of directors of the  corporation or
for any other purpose.

                                   ARTICLE IV

                                PREEMPTIVE RIGHTS

         No  holder  of any of the  shares of any class or series of stock or of
options,  warrants or other rights to purchase  shares of any class or series of
stock or other securities of the corporation  shall have any preemptive right to
purchase or subscribe for any unissued  stock or security of any class or series
or any  additional  shares  of any  class or  series  to be  issued by reason of
increase in the  authorized  capital  stock of the  corporation  of any class or
series,  bonds,  certificates of  indebtedness,  debentures or other  securities
convertible  into or  exchangeable  for stock of the corporation of any class or
series.  Any such unissued stock,  additional  authorized issue of shares of any
class or series of stock or  securities  convertible  into or  exchangeable  for
stock or carrying  any right to purchase  stock,  may be issued and  disposed of
pursuant to resolution  of the Board of Directors to such persons,  whether such
holders or others,  and upon such terms as may be deemed  advisable by the Board
of Directors in the exercise of its sole discretion.
