                             USA WASTE AND SANIFILL
                        JOINTLY ANNOUNCE MERGER AGREEMENT

         Houston,  Texas (June 24, 1996) -- USA Waste  Services,  Inc.  (NYSE --
"UW") and  Sanifill,  Inc.  (NYSE  --"FIL")  today  jointly  announced  that the
companies  have  entered into a definitive  merger  agreement,  approved by both
Boards of Directors, whereby Sanifill stockholders will receive 1.7 shares of






USA Waste common stock for each Sanifill  common  share.  USA Waste and Sanifill
have received opinions from independent  financial advisors,  Donaldson,  Lufkin
and Jenrette  Securities  Corporation  and Merrill Lynch and Co.,  respectively,
stating that the share exchange ratio is fair from a financial  point of view to
their respective shareholders.  The closing of the merger is subject to approval
by both Companies' stockholders and certain lenders, Hart-Scott-Rodino antitrust
clearance,  opinions  that the merger  will  qualify  as a  tax-free  pooling of
interests transaction and other standard and customary closing requirements.

         USA Waste's  stock price  closed  Friday,  June 21, 1996 at $27-7/8 per
share. Based upon Sanifill's  approximately 25.9 million  outstanding shares and
share equivalents and existing indebtedness, the merger would be valued at about
$1.6 billion.  The Companies anticipate that the merger should close in the late
summer or early fall.

         John E. Drury,  Chairman and Chief Executive Officer of USA Waste, will
retain that position,  and Rodney R. Proto,  President,  Chief Operating Officer
and  Director of Sanifill  will assume these  positions at USA Waste.  Donald F.
Moorehead,  Jr.,  Vice  Chairman  and  Chief  Development  Officer,  and Earl E.
DeFrates,  Executive Vice  President and Chief  Financial  Officer,  will retain
these positions at USA Waste.  Mr. Proto and two designees from Sanifill's Board
will join USA Waste's Board, which will remain a twelve person board.

         Lorne D. Bain, Chairman and Chief Executive Officer of Sanifill, and J.
Chris Brewster,  its Chief Financial  Officer,  will relinquish their posts, but
both will assist with merger transition  matters.  David  Sutherland-Yoest,  USA
Waste's current  President and Chief Operating  Officer,  will continue to serve
the Company as Regional Vice  President of operations in the  northeastern  U.S.
and Canada,  as well as being a Vice  Chairman  and  Director  of the Board.  In
connection  with the merger,  USA Waste will move its  headquarters  to Houston,
Texas.

         The combined  Companies have annualized  revenues of approximately $1.3
billion and total assets in excess of $2 billion.  Giving  effect to the merger,
USA Waste,  currently the third  largest  solid waste company in North  America,
will have 108  collection  operations,  83 landfills with total airspace of over
2.5 billion  cubic gate yards,  45 transfer  stations  and 31 other  operations,
serving  over 1.7 million  customers  in 33 states,  the  District of  Columbia,
Canada,  Mexico  and Puerto  Rico.  The  ongoing  acquisition  programs  of both
Companies  will be  continued  during the  pendency of the merger,  resulting in
further growth.

         Mr. Drury stated,  "The  combination  of these two fine  companies will
provide significant  benefits to both stockholder groups. We expect the combined
company  to  continue  to  reflect  the  strong  earnings  growth  that each has






demonstrated  over  the  past  several  years.  The  merger  is  expected  to be
immediately  accretive  to  USA  Waste's  earnings  per  share  as a  result  of
substantial  annual  cost  savings  and  operational  synergies  which have been
identified."  Mr.  Drury  stated  that,  "the  combined  company  will be strong
operationally and financially and have outstanding management talent


                                       -5-






at all levels of the  organization.  This  combination  will enhance USA Waste's
capacity to continue to benefit from the substantial  growth  opportunities that
exist in our industry."

         Mr. Bain said, "This merger is a thoroughly logical  transaction,  that
makes  operating  and  financial  sense  across the  board.  The  synergies  are
significant and sustainable, and the combined management team has the skills and
capabilities needed by a growth company in a consolidating industry. This merger
will create  North  America's  premier  solid waste  company,  to the benefit of
employees, customers and stockholders."
