      Third Amendment and Waiver to Amended and Restated Credit Agreement

To each of the Lenders
party to the Credit Agreement
referred to below

Ladies and Gentlemen:

     Reference is hereby made to that certain Amended and Restated Credit
Agreement dated as of June 30, 1999, as amended (the "Credit Agreement"),
between the undersigned, Everest Healthcare Services Corporation (the
"Company"), the Lenders party thereto, and Harris Trust and Savings Bank, as
Agent. All capitalized terms used herein without definition shall have the same
meanings herein as such terms have in the Credit Agreement.

     The Company has requested that the Lenders make certain amendments to the
financial covenants and waive the Company's non-compliance with Section 7.17 of
the Credit Agreement with respect to an October, 1999 redemption of certain
capital stock of the Company, and the Lenders are willing to do so under the
terms and conditions set forth in this agreement (herein, the "Amendment").

1.   Amendment.

     Subject to the satisfaction of the conditions set forth in Section 3 below,
Section 7.9 of the Credit Agreement shall be amended and restated in its
entirety to read as follows (which shall be deemed effective as of October 19,
1999):

               "Section 7.9. Net Worth. The Company shall, at all times,
          maintain Net Worth of not less than the sum of (a) $40,435,259, plus
          (b) 75% of Net Income for each fiscal year of the Company ending after
          the date hereof (commencing with the fiscal year ending September 30,
          2000) for which such Net Income is a positive amount (i.e., there
          shall be no reduction to the amount of Net Worth required to be
          maintained hereunder for any fiscal year in which Net Income is less
          than zero), plus (c) 100% of the Net Issuance Proceeds from the
          issuance of any equity securities by the Company or its Restricted
          Subsidiaries subsequent to the date of this Agreement."

2.   Waiver.

     The Company acknowledges that on October 19, 1999, as a result of a court
ordered divorce settlement, the Company purchased 65,134 shares of its capital
stock from Tom Creel, a director of the Company for an aggregate price of
approximately $849,999 (the "Purchase"). The Company hereby requests that the
Required Lenders waive, effective as of the date of the
<PAGE>

Purchase, (i) the provisions of Section 7.17 of the Credit Agreement with
respect to the Purchase and (ii) Section 7.9 of the Credit Agreement in effect
prior to the date of this Amendment to the extent the Company would not be in
compliance with Section 7.9 as a result of the Purchase (the "Purchase
Defaults"). Upon the effectiveness of this Amendment as hereinafter set forth,
the Required Lenders hereby waive the Purchase Defaults effective as of the date
of the Purchase.

3.   Conditions Precedent.

     The effectiveness of this Amendment is subject to the satisfaction of all
of the following conditions precedent:

     executed and delivered this Amendment;

          3.2.  The Restricted Subsidiaries shall have executed and delivered
     their consent to this Amendment in the space provided for that purpose
     below; and

          3.3.  Legal matters incident to the execution and delivery of this
     Amendment and to the transactions contemplated hereby shall be reasonably
     satisfactory to the Agent and its counsel.

4.   Representations.

     In order to induce the Lenders to execute and deliver this Amendment, the
Company hereby represents to the Agent and the Lenders that as of the date
hereof, and after giving effect to this Amendment, the representations and
warranties set forth in Section 5 of the Credit Agreement are and shall be and
remain true and correct and the Company and its Restricted Subsidiaries are in
compliance with all of the terms and conditions of the Credit Agreement and the
other Loan Documents and no Default or Event of Default has occurred and is
continuing under the Credit Agreement or shall result after giving effect to
this Amendment.

5.   Termination of Y2K Revolving Credit Commitments.

     Pursuant to Section 3.8(a) of the Credit Agreement, the Company hereby
requests, and the Lenders hereby agree and acknowledge that as of April 1, 2000,
the Y2K Revolving Credit Commitments shall terminate in whole.

Agreement, or any other instrument or document executed in connection therewith,
or in any certificate, letter or communication issued or made pursuant to or
with respect to the Credit Agreement, any reference in any of such items to the
Credit Agreement being sufficient to refer to the Credit Agreement as amended
hereby.

     6.3.  The Company agrees to pay on demand all reasonable, documented costs
and expenses of or incurred by the Agent in connection with the preparation,
execution, and delivery of this Amendment and any other instruments and
documents contemplated hereby, including the reasonable, documented fees and
expenses of counsel for the Agent.

     6.4.  This Amendment may be executed in any number of counterparts, and by
the different parties on different counterpart signature pages, all of which
