TAMPA, Fla.--Dec. 10, 2003--Centrics Holding Corporation (formerly NuMed Home Health Care, Inc.) (Pink Sheets:NUMD) (the "Company") today announced the closing of various transactions announced November 24, 2003.

Any statement made in the foregoing is based on our current best estimate given the information we have as of this date.

Our estimates are based on assumptions, which foresee, among others, adding a minimum of four new client-companies during calendar 2004. Although we are not required to update our estimates until our quarterly or annual reports, we undertake to alert our shareholders as meaningful changes occur.
