PRESS RELEASE   DECEMBER 11, 1998
    
         Sandy, Utah.  Cherokee Minerals and Oil, Inc. ("Cherokee") announced
today that it has closed its Agreement and Plan of Reorganization for the
acquisition of all of the outstanding shares of common stock of Environmental
Systems & Solutions, Inc. ("ESSI"), based in Draper, Utah, in a tax-free,
stock-for-stock reorganization.  In accordance with the terms of the
Reorganization, the shareholders of ESSI have acquired 91% of the outstanding
shares of Cherokee.  The former shareholders of Cherokee own approximately
1,920,000 shares and the former shareholders of ESSI will own approximately
22,080,000 shares, including shares reserved for issuance in accordance with
formerly outstanding ESSI stock options. 
    
         In conjunction with the Reorganization new Directors were elected
including; Culley W. Davis, Ronald L. LaFord, Mark S. Brewer, John W. Nagel
and Bruce H. Haglund.  The following Officers were also appointed; Culley W.
Davis as the Chairman of the Board and Chief Executive Officer, Ronald L.
LaFord as President and Chief Operation Officer, Mark S. Brewer as Vice
President, John W. Nagel as Chief Financial Officer, and Bruce H. Haglund as
Secretary.
    
         The Company intend to act immediately to change its name to Hydo-Maid
International, Inc., to more closely reflect the business of the Company.  
    
         The HydroMaid is the only non-electric, completely water-powered
garbage disposer in the world.  Instead of using a conventional electric
motor, the HydroMaid is powered by common household water pressure from the
existing cold water line to the kitchen sink.  Water pressure drives a
patented servomechanism, which in turn oscillates five stainless steel cutting
blades.  The blades cut food waste into small particles, reducing drain
clogging problems and promoting faster decomposition as an aid to the
environment.  In addition to the normal kitchen refuse
processed by conventional garbage disposers, HydroMaid easily and quietly
processes chicken bones, corn husks, potato peelings, stalks of celery,
avocado pits, nut shells, and other fibrous food waste that most conventional
garbage disposers have difficulty processing. However, if
silverware is accidentally dropped into the HydroMaid, the oscillating motion
shifts automatically into a harmless mode until the object is removed, damage
free.
    
         The HydroMaid will be marketed at a suggested retail price in the
United States of $299.95.  With its simple design and sturdy construction, the
dependable HydroMaid will carry an unprecedented 10-year, unconditional
replacement warranty.  While broken electric-powered disposers are sent to
landfills, ESSI will purchase old HydroMaid units for $10 per unit and offer a
$25 rebate on replacement units to recycle many of the HydroMaid's component
parts.  ESSI is currently completing its manufacturing, assembly, and
distribution arrangements and  anticipates that full-scale sales efforts will
commence in the first quarter of 1999.
