Investor News Release

MIDDLETOWN, NY--(BUSINESS WIRE)--April 26, 2000--Mediacom Communications Corporation (Nasdaq: MCCC) announced today that it has completed an $8.0 million acquisition of cable systems owned by MidAmerican Cable Systems, L.P. The acquired systems serve more than 5,000 basic subscribers within the Company's Midwest region.

As previously disclosed, the Company has also executed two definitive agreements to acquire cable systems serving, in total, approximately 6,500 basic subscribers for an aggregate purchase price of approximately $12.5 million. In addition, the Company has signed several letters of intent to acquire cable systems serving, in total, approximately 82,500 basic subscribers for an aggregate purchase price of approximately $164.5 million. A substantial portion of the basic subscribers served by these pending acquisitions are contiguous or in close proximity to the Company's operating clusters in the Central, Midwest and North Central regions.

The acquisitions under letter of intent are subject to the negotiation and completion of definitive documentation, which will include customary representations and warranties and will be subject to a number of closing conditions, including regulatory approvals and other third party consents. No assurance can be given that such definitive agreements will be entered into or that if entered into, these acquisitions will be consummated. The Company expects to complete its pending acquisitions during fiscal year 2000.

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 over 1.2 million homes and serve approximately 820,000 basic subscribers in 23 states, including its pending acquisitions. Mediacom was founded in July 1995 by Rocco B. Commisso, its Chairman and Chief Executive Officer, to acquire and develop cable television systems serving principally non-metropolitan markets in the United States.
