MICHAEL J. MAHONEY brings more than 25 years of fiscal and operational
leadership to the RCN executive management team, and has established
himself as a solid performer in the rapidly growing residential
telecommunications industry. Mr. Mahoney joined the former C-TEC
Corporation in June 1991 as Executive Vice President of its cable
television unit, responsible for all cable television operations, sales
and marketing, public affairs, engineering, and customer service. In

performance despite government-mandated rate reductions totaling 18%
over a two-year period. In February, 1994, Mr. Mahoney was appointed
President and Chief Operating Officer, responsible for guiding the
company’s various telecommunications operations, as well as all of C-

company. He also served on Megacable’s Board of Directors since January,
1995. In June of 1995, Mr. Mahoney was elected to C-TEC’s Board of
