ITEM 1.01:        ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

         Effective January 1, 2005, the vesting schedule of restricted stock
awards granted and to be granted under the 1991 Long Term Stock Incentive Plan
is being revised. Under the revised schedule, effective January 1 of the
calendar year in which a participant attains age 66, restricted stock awards
with more than five annual installments remaining to vest will be accelerated so
that shares that would otherwise vest beyond the next five annual installments
will vest evenly in whole shares on the next five original vesting dates. This
revision applies to all participants (including the named executive officers),
except for existing awards to Richard A. Manoogian, the Chairman and Chief
Executive Officer.
