Investor News Release

MIDDLETOWN, N.Y.--(BUSINESS WIRE)--April 11, 2000--Mediacom Communications Corporation (Nasdaq: MCCC) announced today that it has completed the acquisition of Rapid Communications Partners, L.P. ("Rapid") cable systems serving 6,000 basic subscribers for a purchase price of $8.0 million. The Rapid systems are located primarily in Kentucky and Illinois.

As previously announced, Mediacom also has signed three separate definitive agreements to acquire cable systems serving 12,000 basic subscribers for $21.4 million and a letter of intent to acquire systems serving an additional 9,000 basic subscribers for $16.0 million. These acquisitions are expected to close in the second and third quarters of 2000.

In making the announcement, Rocco B. Commisso, Mediacom's founder, Chairman and CEO stated, "The Rapid acquisition adds customers and systems that are contiguous to our own, allowing us to consolidate operations and eliminate nearly all of the headend facilities through fiber interconnection. As with our other acquisitions, we expect to quickly make the capital investments necessary to introduce an expanded array of new products and services to our new customers, including digital cable television and high-speed Internet access."

Mediacom Communications Corporation is the 9th largest cable television company in the United States, based on customers served by wholly-owned systems after giving effect to its pending acquisitions and recently announced industry transactions. Mediacom's cable systems pass approximately 1.1 million homes and serve approximately 747,000 basic subscribers in 22 states, including its pending acquisitions. Mediacom was founded in July 1995 by Rocco B. Commisso to acquire and develop cable television systems serving principally non-metropolitan markets in the United States.
