MIDDLETOWN, N.Y.--(BUSINESS WIRE)--March 15, 2000--Mediacom Communications Corporation (Nasdaq:MCCC) announced today that it has signed two separate asset purchase agreements to acquire for $12.5 million cable systems serving approximately 7,000 basic subscribers in Iowa and Minnesota.

As previously announced, Mediacom has also signed two separate asset purchase agreements to acquire for $16.9 million cable systems serving approximately 12,000 basic subscribers in Illinois and Kentucky.

In addition, Mediacom has signed a letter of intent to acquire for $16.0 million cable systems serving approximately 9,000 basic subscribers in Illinois.

In making the announcement, Rocco B.
