("Grantee"), with respect to the following facts:

     Pursuant and subject to the Micron Enviro  Systems,  Inc. 2002 Stock Option
Plan, a copy of which is furnished to the Grantee with a copy of this  Agreement
and  the  provisions  of  which,  by  this  reference,  are  made a part of this

and until April 3, 2008,  the Grantee  shall have the right to purchase from the
Corporation  350,000  shares of the  Corporation's  $.001 par value common stock
("Option"). The Grantee shall exercise the Option by delivery to the Corporation
of a notice  of  exercise  accompanied  by a  certified  or  cashier's  check or

          ------------------------------------------
only by Grantee during his or her lifetime. The Grantee will hold the Option and
the rights  constituent  thereto for  investment  and not with an  intention  of
distribution,  and upon exercise will deliver a letter  confirming the Grantee's
nondistributive intent with respect to the shares of the Corporation's $.001 par
value  common  stock  received as a result of the  exercise  of the Option.  The
Grantee  will not  transfer or assign the Option,  except by Will or the laws of

changes in the Corporation's capital structure or the Corporation's business, or
any  merger  or  consolidation  of  the  Corporation  or  any  issue  of  bonds,
debentures,   preferred   stock  having  a  preference   to  or  affecting   the
Corporation's  capital  stock or the  rights  thereof,  or the  issuance  of any

the Corporation  shall effect a subdivision or  consolidation of shares or other
capital  readjustment,  the payment of a stock  dividend,  or other  increase or
reduction of the number of shares of such common  stock  issued and  outstanding
without receiving  compensation therefor in money,  services,  or property,  the
