                             Donna Moore Named CEO



     FT. LAUDERDALE,  FL. MARCH 25, 1996 -- Discovery Zone, Inc. announced today
that it has filed a voluntary  petition under Chapter 11 of the U.S.  Bankruptcy
Code in the U.S. Bankruptcy Court for the District of Delaware. The Company said
that  it  elected  to  seek  court   protection  in  order  to  facilitate   the
implementation of its operational turnaround and a financial restructuring.

     Discovery  Zone said that it will operate in the normal  course of business
during the  reorganization  proceeding and that it has received a commitment for
$15 million in debtor-in-possession ("DIP") financing.

     "We believe  reorganizing  under Chapter 11 is in the best interests of the
Company,"  said Donna  Moore,  Chief  Executive  Officer of Discovery  Zone.  "A
successful  Chapter 11  reorganization  will address the problems  caused by the
Company's rapid expansion and put Discovery Zone on stronger financial footing."


     Moore  continued:  "Discovery  Zone  is a  viable  concept,  and we have an
opportunity  to  revitalize  our  operations  with new  marketing  programs  and
entertainment  concepts that will improve the Discovery Zone experience for kids
and their parents. "

     Discovery Zone said that it would move  immediately  to close  unprofitable
store  locations in order to improve its operating  cost structure and allow the
Company to focus on core  markets  and  locations.  Discovery  Zone said that it
would also continue to seek to reduce  operating  costs in remaining  locations,
primarily  through the  renegotiation of unfavorable  leases to reduce occupancy
costs.

     Separately,  Discovery  Zone  announced  that  Donna  Moore has been  named
President and Chief Executive Officer and a director of the Company.
