 of Articles 2 hereof, as well as such other terms and conditions as Centene may
 reasonably require for purposes of complying with all federal and state
 securities laws, any requirements imposed by TDI and/or any other legal
 requirements.

          ---------

               (c) All Other Regions. Model Provider Agreements executed by

attached hereto as Exhibit J.
                   ---------

         6.2   Master Agreement. That certain Master Agreement, by and among
               ----------------
TACHC, Centene, Superior, CHCN, et al., (the "Master Agreement") shall be
terminated pursuant to Section 7.1 (a) thereof effective at the Purchase

Amended and Restated Shareholders Agreement in the form as attached hereto as
Exhibit K.
---------

         6.4   CHCN Exclusivity.
               -----------------

               (a) So long as at all times from the date hereof (i) Centene
complies with the provisions of this Agreement in all material respects and (ii)
Superior complies with the provisions of the Provider Agreements in all material
respects, then from and after the date

                                       8

hereof until the consummation of the Exchange or the Contingent Purchase, as the
case may be, CHCN shall not directly or indirectly undertake any activities in
the State of Texas, or enter into any arrangement or agreement with any other
person, entity or organization that, at the time undertaken or entered into,
would compete (or was undertaken or entered into for the purpose of competing)
with Superior or any business in which Superior is engaged. Without limiting the
generality of the foregoing, this provision expressly prohibits CHCN from:
investing in a Texas licensed health maintenance organization ("HMO") that
competes with Superior in the Medicaid managed care market or any management
company providing management services to such an HMO; by itself or in
conjunction with any third party forming, owning, operating, administering,
managing and/or controlling any such Texas licensed HMO; and (subject to the
terms of the Model Provider Agreements and Centene's waiver of this requirement
from time to time as to specific clinic members of CHCN) entering into a
provider contract, directly or indirectly, with another Medicaid managed care
HMO in the State of Texas.

               (b) CHCN acknowledges and agrees that the restrictive covenants
contained in this Section 6.4, are given in consideration of the Centene's
execution of this Agreement and in consideration of, and as a condition to,
consummation by Centene of the transactions contemplated hereby. If a court
construes any one or more of such provisions to state unreasonable restrictions,
then Centene and CHCN request the court to revise such restrictions to make them
reasonable and enforceable to the maximum extent permissible. Moreover, if a
court construes any one or more of such provisions to state unreasonable
restrictions, the validity and enforceability of the remaining provisions shall
remain unaffected.

               (c) CHCN acknowledges that, if CHCN breaches its obligations
pursuant to any provisions of this Section 6.4, then Centene will experience
                                   -----------
irreparable harm for which money damages will not provide an adequate remedy.
Accordingly, Centene shall have the right to injunctive relief to remedy any
such breaches. By seeking injunctive relief first, however, Centene shall not
make an election of remedies and may pursue an action at law. Centene may seek
its legal and equitable remedies either simultaneously or independently, and
shall not waive its right to one form of relief by pursuing another.

         6.5   Pledge Agreement. At the Purchase Closing, that certain Community
               ----------------
Health Centers Network, L.P. Security and Pledge Agreement, by and between CHCN
and Centene, (the "Pledge Agreement") shall be terminated and any collateral
held by Centene under the Pledge Agreement shall be returned to CHCN.

         6.6   Further Assurances: Regulatory Compliance. The parties hereto
               -----------------------------------------
will cooperate with each other and will execute and deliver such further
instruments and do such further acts and things as may be required to carry out
the intent and purpose of this Agreement, including without limitation (i) the
filing with the TDI of such forms, documents and other information and (ii) the
taking of any and all other actions as are requested or required by the TDI to
obtain the necessary regulatory approval for all of the transactions
contemplated hereby.
