Dear Lou:

         Reference is hereby made to the One Million Three Hundred Two Thousand
One Hundred Eighty Two Dollars ($1,302,182) Non-Negotiable Promissory Note dated
May 10, 1997 issued by Community Care Services, Inc. ("CCS") to you (the
"Note"). We have agreed that the payment of the Note will be accelerated under
the following terms and conditions:

         1. Promptly upon the execution of this Agreement, CCS will issue to you
a stock certificate for Two Hundred Ninety Three Thousand Fifty Six (293,056)
shares of CCS common stock. The issuance of such stock represents payment in
full for eighty percent (80%) of the Note. You understand that the shares to be
issued to you will be restricted stock, will bear a legend to that effect, and
may not be transferred unless an exception from applicable federal and state
registration requirements is available to you.

         2. Of the remaining Two Hundred Ninety Three Thousand Fifty Six Dollars
($293,056.00) of the Note, Seventy Three Thousand Two Hundred Sixty Four Dollars
($73,264.00) will be paid to you upon the execution of this Agreement. The
balance (inclusive of tax gross up) of Two Hundred Seventy Eight Thousand Three
Hundred Ninety Four Dollars ($278,394.00) will be paid to you as additional base
compensation under your Employment Agreement with CCS dated May 10, 1997 in
equal installments over the remaining twenty-seven (27) months of the term,
commencing March 1, 1998, resulting in an increase of Ten Thousand Three Hundred
Eleven Dollars ($10,311.00) per month to your base compensation. Simultaneous
with the execution of this Agreement, we will enter into an Amendment to your
Employment Agreements reflecting such increased compensation. Such additional
compensation will not be subject to forfeiture in the event your employment
terminates for any reason.

         3. Upon your receipt of the stock certificate referenced in Section 1,
the check for Seventy Three Thousand Two Hundred Sixty Four Dollars ($73,264)
referenced in Section 2, and the Amendment to your Employment Agreement, you
will surrender to CCS the Note, marked "Paid in Full". You hereby acknowledge
and agree that the aforementioned payment and deliveries constitutes
satisfaction in full of all obligations of CCS to you under the Note.
