FOR IMMEDIATE RELEASE


            COMCAST CORPORATION AND JONES INTERCABLE ANNOUNCE CABLE
                   SYSTEM SWAPS WITH ADELPHIA COMMUNICATIONS


Philadelphia, PA -- May 26, 1999: Comcast Corporation and Jones Intercable, Inc.
announced  today   agreements  to  swap  certain  cable  systems  with  Adelphia
Communications.  These cable system swaps will continue to strengthen  Comcast's
Mid-Atlantic  super-cluster,  encompassing cable systems in New Jersey,  eastern
Pennsylvania,  Maryland,  Delaware,  Washington  DC and  Virginia.  These system
swaps,  together  with other  pending  acquisitions  and  investments  will make
Comcast's Mid-Atlantic super-cluster one of the largest cable system clusters in
the nation with  interests  in more than four  million  owned and managed  cable
subscribers.  In addition, they will enhance Comcast's and Jones' cable clusters
in the  Midwest,  in Michigan  and  Indiana,  and also in West  Florida.  In the
aggregate,   these  swaps  will  add  approximately  464,000  cable  subscribers
currently held by Adelphia to Comcast and Jones markets.  In exchange,  Adelphia
will receive  current Comcast and Jones systems  serving  approximately  440,000
subscribers  in the greater Los Angeles area as well as in Palm Beach,  Florida.
All systems involved in the  transactions  will be valued based upon independent
appraisals  with any  difference  in  relative  value to be funded  with cash or
additional cable systems.  The system swaps are subject to customary closing and
regulatory approvals and are expected to close by mid-2000.
