VIA FACSIMILE

Mr. Donald Winstead, President
Casa Solaz, Inc.
17246 Quail Court
Morgan Hill, CA  95037

Dear Mr. Winstead:

      Purus,  Inc. ("Purus") is pleased to confirm its commitment
to  make funds available to provide additional debt financing  to
Casa  Solaz, Inc., a Nevada corporation (the "Company"),  in  the
amount  of  $2,200,000  on the same terms as  the  existing  loan
between  the parties.  Purus is prepared to make this  commitment
in  reliance on the agreement of the Company's holders of capital
stock  to  exchange  their  shares for Purus  common  stock  (the
"Acquisition")  subject  to the terms  and  conditions  contained
herein  and  in  the  attached  Summary  of  Proposed  Terms  and
Conditions  (the "Term Sheet").  (This letter and the Term  Sheet
are  sometimes collectively referred to herein as the  "Letter").
Any  capitalized term used and not otherwise defined herein shall
have the meaning ascribed to such term in the Term Sheet.

      The  commitment  of  Purus  hereunder  is  based  upon  the
financial  and  other information regarding the Company  and  its
subsidiaries  provided  to Purus and is subject  to  the  various
conditions precedent described in the Term Sheet and to the usual
reservations,  among others, that there shall not  have  occurred
after the date of such information, in the sole opinion of Purus,
either  any  material  adverse change in  the  business,  assets,
liabilities   (actual  or  contingent),  operations,   conditions
(financial  or  otherwise) or prospects of the  Company  and  its
subsidiaries  taken  as a whole, or any changes  in  governmental
regulations,  monetary  policy  or  market  conditions.   If  the
continuing  review by Purus of the Company discloses  information
relating  to  conditions  or events not previously  disclosed  to
Purus  or  relating to new information or additional developments
concerning  conditions or events previously  disclosed  to  Purus
that  Purus  in its sole discretion believes may have a  material
adverse effect on the condition (financial or otherwise), assets,
properties,  business operations or prospects of the Company  and
its  subsidiaries  taken  as a whole, Purus,  may,  in  its  sole
discretion,  decline  to provide the Financing  or  complete  the
Acquisition.

      The  Company  hereby represents, warrants and covenants  to
Purus  that (i) all information, which has been, or is hereafter,
made   available  to  Purus  by  the  Company  or  any   of   its
representatives in connection with the transactions  contemplated
hereby ("Information"), is, and will be, complete and correct  in
all  material  respects and does not, and will not,  contain  any
untrue  statement  of a material fact or omit  to  state  a  fact
necessary to make the statements contained therein not misleading
and  (ii)  all financial projections concerning the Company  that
have  been,  or  are hereafter, made available to  Purus  by  the
Company  or  any of its representatives (the "Projections")  have
been,  or  will be, prepared in good faith based upon  reasonable
assumptions.  The Company also agrees to furnish Purus with  such
information and Projections as it may reasonably request  and  to
supplement the Information and the Projections from time to time,
through  and  including the closing date of the Acquisition  (the
"Closing  Date"),  so that the representation  and  warranty  set
forth in the preceding sentence is correct on the Closing Date.

      Each of the parties hereto agree that the other party shall
(i) have no liability (whether direct or indirect, in contract or
tort  or otherwise) to security holders or creditors arising  out
of,  related to, or resulting from, the transactions contemplated
herein,  except to the extent that such liability is found  by  a
judgment  of  a court of competent jurisdiction to have  resulted
from   gross  negligence  or  willful  misconduct  or   (ii)   be
responsible or liable for any consequential damages that  may  be
alleged as a result of this Letter.

      The provisions of the immediately preceding paragraph shall
remain  in full force and effect regardless of whether definitive
documentation  for  the  Financing  and  Acquisition   shall   be
completed,  executed  and  delivered,  and  notwithstanding   the
termination of this Letter or the commitment of Purus hereunder.

      Please note that, except with respect to the provisions  of
the preceding two paragraphs, the commitment proposed herein does
not  constitute  a binding obligation of either  the  Company  or
Purus, nor does it define all of the terms and conditions of  the
Financing  and  Acquisition, but is a framework  upon  which  the
documentation for the proposed transactions would be  structured,
and  is  a  basis for further discussion and negotiation  of  the
terms as may be appropriate.  Among other things, the Acquisition
would  be  subject to all of the Conditions Precedent to  Closing
set  forth  in  the Term Sheet, and those matters which  are  not
covered by or made clear in this Letter are subject to the mutual
agreement of the parties.

      This  Letter  (i)  shall be governed by, and  construed  in
accordance  with,  the laws of the State of  California,  without
regard  to  any  choice-of-law principles thereof,  (ii)  may  be
executed in counterparts, which, taken together, shall constitute
an original, (iii) shall be amended or modified only in a writing
executed  by  the parties hereto, (iv) shall not be  assigned  or
transferred  by  the  Company (whether by  operation  of  law  or
otherwise)  without the prior written consent of Purus,  and  (v)
supersedes  and  replaces  any and all  proposals  or  commitment
letters  previously  delivered  by  Purus  to  the  Company.   In
addition, no party has been authorized by Purus to make any  oral
or written statements inconsistent with this Letter.

      The  commitment  proposed  herein  will  be  available  for
acceptance  until  5:00 p.m. (Pacific Daylight Savings  time)  on
April 17, 1998, unless further extended in writing by Purus.

      We are delighted to have this opportunity to work with you.
If  the  terms  of  the  Letter meet with your  approval,  please
indicate your acceptance by signing and dating the enclosed  copy
of this Letter, and then returning the same to the undersigned.


                                   Very truly your,

                                   PURUS, INC.

                    As used herein, a "Change of Control" means a
                    change  of control of Purus of a nature  that
                    would  be required to be reported in response
                    to  Item  6(e) of Schedule 14A of  Regulation
                    14A promulgated under the Securities Exchange
                    Act  of 1934, as amended (the "Exchange Act")
                    (as  in  effect on the Closing Date), whether
                    or   not  Purus  is  then  subject  to   such
                    reporting   requirement;   provided,    that,
                    without  limitation, such a Change of Control
                    shall be deemed to have occurred if:

                           (i)   any  "person"  (ad  defined   in
                    Sections 13(d) and 14(d) of the Exchange Act)
                    is  or  becomes  the "beneficial  owner"  (as
                    defined  in  Rule  13d-3 under  the  Exchange
                    Act),  directly or indirectly, of  securities
                    of Purus representing thirty percent (30%) or
                    more  of the combined voting power of Purus's
                    then    outstanding   securities;   provided,
                    however,  that no Change of Control shall  be
                    deemed  to  have  occurred if  prior  to  the
                    acquisition of such thirty percent  (30%)  of
                    the  combined  voting power of  Purus's  then
                    outstanding  securities, a  majority  of  the
                    Continuing   Directors  (as  defined   below)
                    approves such acquisition; or

                          (ii)  if  there shall  cease  to  be  a
                    majority  of the Board of Directors of  Purus
                    (the   "Board")   comprised   of   Continuing
                    Directors; or

                          (iii)      the  stockholders  of  Purus
                    approve  a merger of consolidation  of  Purus
                    with  any  other corporation,  other  than  a
                    merger or consolidation which would result in
                    the  voting  securities of Purus  outstanding
                    immediately   prior  thereto  continuing   to
                    represent (either by remaining outstanding or
                    by  being converted into voting securities of
                    the surviving entity) at least eighty percent
                    (80%)  of  the combined voting power  of  the
                    voting  securities of Purus or such surviving
                    entity  outstanding  immediately  after  such
                    merger or consolidation; or

                           (iv)  if  any  recapitalization  event
                    occurs  as  a result of which the holders  of
                    voting   securities   of  Purus   outstanding
                    immediately prior thereto do not continue  to
                    hold  at  least eighty percent (80%)  of  the
                    combined   voting   power   of   the   voting
                    securities  of Purus immediately  after  such
                    recapitalization event; or

                         (v)  the stockholders of Purus approve a
                    plan  of complete liquidation of Purus or  an
                    agreement  for  the  sale or  disposition  by
                    Purus  of all or substantially all of Purus's
                    assets; or

                          (vi) a majority of the "named executive
                    officers"  set forth in Purus's  most  recent
                    Proxy Statement or Annual Report on Form 10-K
                    or  Form 10-KSB, as the case may be, cease to
                    occupy such positions within a period of  365
                    consecutive days.

                    As  used herein, "Continuing Directors" means
                    individuals  who constitute the Board  as  of
                    the   date   of  the  Letter  and   any   new
                    director(s)  whose election by the  Board  or
                    nomination    for   election    by    Purus's
                    stockholders  was approved by a  vote  of  at
                    least two-thirds (2/3) of the directors  then
                    still in office who either were directors  as
                    of  the  date  hereof or  whose  election  or
                    nomination  for  election was  previously  so
                    approved.
