concurrent with this Agreement, and thus, upon disposition of the Properties to
a third party, is to be retained by CareMatrix of Massachusetts, Inc. In
addition, in the event the Actual Net Sale Proceeds received by CareMatrix of
Massachusetts, Inc. with respect to a particular Property upon disposition to a
third party exceeds the "Estimated Net Sale Proceeds" set forth above, such
excess shall be first paid to CareMatrix of Massachusetts, Inc. to the extent of

balance to retained by CareMatrix of Massachusetts, Inc. and applied against the
receivable due to CareMatrix of Massachusetts, Inc. and its affiliates from the
Chancellor Entities and their affiliates as a reduction of such receivable. In
the event the Actual Net Sale Proceeds received by CareMatrix of Massachusetts,
Inc. with respect to a particular Property upon disposition is less than the
"Estimated Net Sale Proceeds" set forth above, such shortfall shall be added to
the receivable due to CareMatrix of Massachusetts, Inc. and its affiliates from
the Chancellor Entities and their affiliates as an increase in such receivable.

      EXAMPLE NO. 1: If the Actual Net Sale Proceeds received by CareMatrix of
Massachusetts, Inc. upon the disposition of the Bayport Property is $1,000,000,

for its own account, and $323,290 would be retained by CareMatrix of
Massachusetts, Inc. and applied against the receivable due to CareMatrix of
Massachusetts, Inc. and its affiliates from the Chancellor Entities and their
affiliates as a reduction of such receivable.

Massachusetts, Inc. upon the disposition of the Bayport Property is $400,000,

and $84,924 would be added to the receivable due to CareMatrix of Massachusetts,
Inc. and its affiliates from the Chancellor Entities and their affiliates as an
increase in such receivable.

      EXAMPLE NO. 3: If the Actual Net Sale Proceeds received by CareMatrix of

of Massachusetts, Inc. and applied against the receivable due to CareMatrix of
