      CASA SOLAZ, INC., a corporation duly organized and existing
under the laws of the state of Nevada (hereinafter referred to as
the  "Company"), for value received, hereby promises  to  pay  to
PURUS,  INC., a Delaware corporation, or its order, the principal
sum   of   TWO   MILLION   TWO  HUNDRED   THOUSAND   US   DOLLARS
($2,200,000.00), on December 31, 1999 (the "Maturity Date"), upon
presentation  and surrender of this promissory note  ("Note")  at
the offices of the Company at 17246 Quail Court, Morgan Hill,  CA
95037, in such lawful money of the United States of America as at
the  time  of  payment shall be legal tender for the  payment  of
public  and private debt, and to pay at that time in like  lawful
tender  interest  on the unpaid principal at  a  rate  per  annum
(calculated on the basis of the actual number of days elapsed  in
a  365-day year) equal to 6%, from and after the date of issuance
or  from the most recent date on which interest has been paid  or
duly provided for, as the case may be.

      This  Note  is subject to the following further  terms  and
material provisions:

      1.    Prepayment.  The Note is subject to prepayment at any
time after the issue date, upon not less than 30 nor more than 50

fixed for repayment, the Note shall cease to bear interest.  Upon
surrender  of  the  Note for repayment in  accordance  with  said
notice of prepayment by the Company, the amount of principal  and
interest  due shall be paid in cash or certified funds.   If  the
Note  is prepaid only in part, the holder shall present the  Note
to  the  Company for notation thereon of such partial  repayment.
The  obligation  of  the  Company to prepay  the  Note  shall  be
evidenced  by  a  resolution of the board  of  directors  of  the
Company.

      2.    Satisfaction and Discharge of Note.  This Note  shall

          payable   hereunder  by  the  Company,  including   all
          principal amounts and interest accrued under the  Note;
          and

          or  approving  as  properly filed  a  petition  seeking
          reorganization, arrangement, adjustment or  composition
          of  or  in respect of the Company or any subsidiary  of
          the  Company under the Federal Bankruptcy  Act  or  any
          other  applicable federal, state, or  foreign  law,  or
          appointing  a receiver, liquidator, assignee,  trustee,

          benefit of creditors, or the admission by it in writing
          of  its  inability to pay its debts generally  as  they
          become due, or the taking of corporate action by any of
          the  Company or its subsidiaries in furtherance of  any
          such actions.

      5.    Acceleration  of Maturity.  If an  event  of  default
occurs and is continuing then, in every such case, the holder may
declare the principal and all accrued interest of the Note to  be
due  and  payable  immediately, by a notice  in  writing  to  the
Company  of  such  default, and upon any such  declaration,  such
principal and accrued interest shall become immediately  due  and
payable.  At any time after such declaration of acceleration  has
been  made and before a judgment or decree for payment  of  money
due  has  been  obtained by the holder, the  holder,  by  written
notice to the Company, may rescind and annul such declaration and
its  consequences if all events of default, other than  the  non-
payment  of  the  principal or interest on the  Note  which  have
become due solely by such acceleration, have been cured or waived
as   provided  below.   No  such  rescission  shall  affect   any
subsequent default or impair any right consequent thereon.

      6.    Suits for Enforcement.  If an event of default occurs
and is continuing, the holder may, in its discretion, proceed  to
protect  and  enforce  its  rights by such  appropriate  judicial
proceedings  as the holder shall deem most effectual  to  protect
and enforce any such rights, whether for the specific enforcement
of  any  covenant or agreement under this Note or in aid  of  the
exercise  of  any power granted herein, or to enforce  any  other
proper remedy.

     (a)  THIS  NOTE SHALL BE DEEMED TO BE A CONTRACT MADE  UNDER
          AND  GOVERNED  BY  THE INTERNAL LAWS OF  THE  STATE  OF
          CALIFORNIA.

     (b)  THE   COMPANY   HEREBY  IRREVOCABLY  SUBMITS   TO   THE
          JURISDICTION  OF ANY CALIFORNIA STATE OR FEDERAL  COURT
          IN  ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING

          THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING
          MAY BE HEARD AND DETERMINED IN SUCH CALIFORNIA STATE OR
          FEDERAL  COURT.  THE COMPANY HEREBY IRREVOCABLY WAIVES,
          TO  THE  FULLEST EXTENT IT MAY EFFECTIVELY DO  SO,  THE
          DEFENSE OF ANY INCONVENIENT FORUM TO THE MAINTENANCE OF

     (c)  The  Company  irrevocably consents to  the  service  of
          process out of any of the aforementioned courts in  any
          such  action or proceeding by the mailing of the copies
          thereof  by  certified mail, return receipt  requested,
          postage prepaid, to it at its address set forth herein,

          (i)  the  date 10 calendar days after such  mailing  or
          (ii)  any  earlier  date permitted by  applicable  law.
          Nothing in this paragraph shall affect the right of the
          holder to bring proceedings against the Company in  the
          courts of any other jurisdiction or to serve process in
          any other manner permitted by applicable law.

     (d)  THE  COMPANY  AND HOLDER HEREBY KNOWINGLY, VOLUNTARILY,
          AND  INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO  A
          TRIAL  BY  JURY  IN  RESPECT OF  ANY  LITIGATION  BASED
          HEREON,  OR  ARISING OUT OF, UNDER,  OR  IN  CONNECTION
          WITH,  THIS  NOTE OR ANY COURSE OF CONDUCT,  COURSE  OF
          DEALING,  STATEMENTS (WHETHER VERBAL  OR  WRITTEN),  OR
