        of any facility owned or operated by any member of the Company Group (as
        defined below), which renders medical, chiropractic or physical therapy
        services competitive with those of such member.

                b. In addition, the Executive agrees that for the duration of
        the Noncompete Term, he will not, either directly or indirectly: (i)
        make any use of or make known to any competing person, firm, or
        corporation the names or addresses of any potential or pending
        acquisition and/or the names of the patients of any member of the
        Company Group or any other information pertaining to said businesses,
        acquisitions, and/or patients; (ii) call on, solicit or take away, or
        attempt to call on, solicit or take away, any of the business,
        acquisitions, and/or patients of any member of the Company Group with
        whom the Executive became acquainted during his employment or
        association with the Company or any other member of the Company Group,
        for commercial or competitive purposes either for himself of for any
        other person, firm, or corporation, or (iii) solicit or take away or
        attempt to solicit or take away any person then employed (including any
        employee who had been employed by the Company or any other member of the
        Company Group within six (6) months prior to the time of the termination
        of this Agreement) by the Company or any other member of the Company
        Group, for purposes of employment by or any consulting relationship with
        himself or any other person, firm or corporation.

                c. As used herein, the phrase "Company Group" means the Company,
        and any entity that directly or indirectly controls, is controlled by,
        or is under common control with, the Company, and for purposes of this
        definition "control" means the possession, directly or indirectly, of
        the power to direct or cause the direction of the management and
        policies of such entity, whether through the ownership of voting
        securities, by contract or otherwise.

                d. Notwithstanding the provisions of paragraph a above this
        Section 4.3, the Executive may invest in the securities of any
        enterprise (but without otherwise participating in the activities of
        such enterprise) if (i) such securities are listed on any national or
        regional securities exchange or have been registered under Section 12(9)
        of the Securities Exchange Act of 1934 and (ii) the Executive does not
        beneficially own (as defined in Rule 1 3d-3 promulgated under the
        Securities Exchange Act of 1934) in excess of 5% of the outstanding
        capital stock of such enterprise.

                e. The Executive agrees that if a court of competent
        jurisdiction determines that the length of time or any other
        restriction, or portion thereof, set forth in this Section 4.3 if overly
        restrictive and unenforceable, the court may reduce or modify such
        restrictions to those which it deems reasonable and enforceable under
        the circumstances, and as so reduced or modified, the parties hereto
        agree that if a court of competent jurisdiction determines that any
        provision of this Section 4.3 is invalid or against public policy, the
        remaining provisions of this Section 4.3 and the remainder of this
        Agreement shall not be affected thereby, and shall remain in full force
        and effect.

                f. The Executive acknowledges that the business of the Company
        and the other members of the Company Group is national in scope and that
        the restrictions imposed by this Agreement are legitimate, reasonable
        and necessary to protect the Company's and the other members of the
        Company Group's investment in their respective businesses and the
        goodwill thereof. The Executive acknowledges that the scope and duration
        of the restrictions contained herein are reasonable in light of the time
        that the Executive has been engaged in the business of the Company, the
        Executive's reputation in the markets for the businesses of the Company
        and the other members of the Company Group and the Executive's
        relationship with the patients of the members of the Company Group. The
        Executive further acknowledges that the restrictions contained herein
        are not burdensome to the Executive in light of the consideration paid
        therefor and the other


                                       11
<PAGE>   12
        opportunities that remain open to the Executive.  Moreover, the
        Executive acknowledges that he has other means available to him for the
        pursuit of his livelihood.

        g.      The Executive acknowledges and agrees that the Company's
remedies at law for a breach or threatened breach of any of the provisions of
this Section 4.3 would be inadequate and, in recognition of this fact, the
Executive agrees that, in the event of such a breach or threatened breach, in
addition to any remedies at law, the Company, without posting any bond, shall be
entitled to obtain equitable relief in the form of specific performance,
temporary restraining order, temporary or permanent injunction or any other
equitable remedy which may then be available.

SECTION 4.4     CONFIDENTIALITY; SPECIFIC PERFORMANCE.

        a.      The Executive will not at any time (whether during or after his
employment with the Company) disclose or use for his own benefit or purposes,
or the benefit or purposes of any other person, firm, partnership, joint
venture, association, corporation or other business organization, entity or
enterprise other than the Company and any other member of the Company Group,
any Trade Secrets (as defined below) of the Company without first obtaining the
written consent of the Company.

        b.      The Executive will not at any time during his employment with
the Company or for a period of two (2) years after termination of his
employment, disclose or use for his own benefit or purposes or the benefit or
purposes of any other person, firm, partnership, joint venture, association,
corporation or other business organization, entity or
enterprise other than the Company and any other member of the Company Group,
any Confidential Information (as defined below) of the Company or any other
member of the Company Group which is disclosed to or learned by the Executive
during employment with the Company.  The Executive acknowledges that
Confidential Information and materials developed by the Executive, or
Confidential Information and materials received by the Company in confidence
from third parties, are also included within the meaning and provisions of this
Section. 

        c.      As used herein, "Trade Secrets" means the whole or any portion
or phase of technical information, design, process, procedure, formula or
improvement known or used by the Company or any other member of the Company
Group that is



                                       12
<PAGE>   13
valuable and secret (in the sense that it is not generally known to competitors
of the Company).  To the extent consistent with the foregoing, Trade Secrets
include (without limitation) the specialized information and technology that
provide any member of the Company Group with an advantage over competitors or
potential competitors in its industry.

        d.      As used herein, "Confidential Information" means, with respect
to any person, any data or information known by that person related to the
business of the person, other than Trade Secrets, that is of competitive
significance to the person and not generally known by or available to the public
or are maintained as confidential by such person.  To the extent consistent with
the foregoing, "Confidential Information" includes (without limitation): patient
records; cost data (such as labor or material costs pertaining to services) of
the Company; the identity and location of vendors and the terms of sales
(including prices) negotiated with such vendors; data relating to sales - by
patient, by location, by service category, or by sales price; patient lists;
financial information that has not been released to the public; future business
plans, marketing strategies, or advertising campaigns; and personnel files.

        e.      The Executive agrees that upon termination of his employment
with the Company for any reason, he will return to the Company immediately all
memoranda, books, papers, plans, information, letters and other data, and all
copies thereof or therefrom in any way relating to the business of the Company
and any other member of the Company Group, except that he may retain personal
notes, notebooks and diaries.  The Executive further agrees that he will not
retain or use for his account at any time any trade names, trademark or other
proprietary business designation used or owned in connection with the business
of the Company or any other member of the Company Group.

        f.      The Executive acknowledges and agrees that the Company's
remedies at law for a breach or threatened breach of any of the provisions of
this Section 4.4 would be inadequate and, in recognition of this fact, the
Executive agrees that, in the event of such a breach or threatened breach, in
addition to any remedies at law, the Company, without posting any bond, shall
be entitled to obtain equitable relief in the form of specific performance,
temporary restraining order, temporary or permanent injunction or any other
equitable remedy which may then be available.



                                       13

        SECTION 4.5.    GOVERNING LAW.  This Agreement shall be governed by and
construed in accordance with the laws of the State of Texas.

        SECTION 4.6.    ENTIRE AGREEMENT; AMENDMENTS; EFFECTIVENESS.  This
Agreement shall supersede any and all existing employment, change in control or
severance agreements between the Executive and the Company or any of its
respective affiliates and contains the entire understanding of the parties with
respect to the employment of the Executive by the Company.  There are no
restrictions, agreements, promises, warranties, covenants or undertakings
between the parties with respect to the subject matter hereof other than those
expressly set forth herein.  No provisions of this Agreement may be amended or
modified unless such amendment or modification is in writing and signed by each
of the parties hereto.  THIS AGREEMENT AND ANY AMENDMENT HERETO SHALL NOT BE
EFFECTIVE UNLESS AND UNTIL SIGNED BY THE COMPANY AND THE EXECUTIVE.

        SECTION 4.7.    NO WAIVER.  The failure of a party to insist upon
strict adherence to any term of this Agreement on any occasion shall not be
considered a waiver of such party's rights or deprive such party of the right
thereafter to insist upon strict adherence to that term or any other term of
this Agreement.

        SECTION 4.8.    SEVERABILITY.  In the event that any one or more of the
provisions of this Agreement shall be or become invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions of this Agreement shall not be affected thereby.

        SECTION 4.9.    SUCCESSORS.  This Agreement shall inure to the benefit
of and be enforceable by the Executive's personal or legal representatives,
executors, administrators, successors, heirs, distributees, devisees and
legatees.  If the Executive should die while any amount would still be payable
to the Executive hereunder if the Executive had continued to live, all such
amounts, unless otherwise provided herein, shall be paid in accordance with the
terms of this Agreement to the Executive's devisee, legatee or other designee
or, if there is no such designee, to the Executive's estate.  This Agreement
shall not be assignable by the Executive.

        SECTION 4.10.   NOTICE.  For the purposes of this Agreement, notices
and all other communications provided for in the Agreement shall be in writing
and shall be deemed to have been duly given when personally delivered or mailed
by United States registered or certified mail, return receipt requested,
postage prepaid, addressed to the respective addresses set forth in the
opening of this Agreement; provided that all notices to the Company shall be
directed to the



                                       14
<PAGE>   15
attention of the President, or such other address as either party may have
furnished to the other in writing in accordance herewith, except that notices
of change of address shall be effective only upon receipt.

        SECTION 4.11.  ARBITRATION.

                a.      Subject to the Company's right to seek injunctive relief
        in court as provided in Sections 4.3 and 4.4, the parties hereby agree
        to submit all controversies, claims and matters of difference in any way
        related to this Agreement or the performance or breach of the whole or
        any part hereof, to arbitration in Dallas, Texas, according to the rules
        and practices of the American Arbitration Association from time to time
        in force.  Any such dispute shall be decided by three (3) arbitrators.
        Each of the parties to the dispute shall appoint one arbitrator within
        thirty (30) days of the submission of a notice of arbitration, and the
        two party-appointed arbitrators shall appoint the third arbitrator
        within thirty (30) days following the appointment of the last
        party-appointed arbitrator.  All decisions and awards by the arbitration
        tribunal shall be made by majority vote.  If one party fails to appoint
        an arbitrator within the time allotted therefor, or the party-appointed
        arbitrators cannot reach agreement on the third arbitrator within the
        said thirty (30) day period, then the appointing authority for the
        implementation of such procedures shall be the Senior Federal District
        Judge sitting for the Northern District of Texas.  If such rules and
        practices shall conflict with the Texas Rules of Civil Procedure or any
        other provisions of Texas law then in force, such Texas rules and
        provisions shall govern.  Arbitration of any such controversy, claims or
        matter of difference shall be a condition precedent to any legal action
        thereon, so, in the event that arbitration fails to settle any dispute
        arising in connection with this Agreement, each of the parties hereto
        agrees to submit to the jurisdiction of the courts of the State of Texas
        in any action or proceeding arising out of or relating to this
        Agreement.  This submission and agreement to arbitration shall be
        specifically enforceable.

                b.      Awards shall be final and binding on all parties to the
        extent and in the manner provided by Texas law; provided that an
        arbitration award shall not be binding on the Company to the extent such
        award exceeds the maximum amount the Company would be required to pay
        the Executive pursuant to the express terms of this Agreement.  All
        awards may be filed by any party with the Clerk of the District Court in
        the County of Dallas, Texas and an appropriate judgment entered thereon
        and execution issued therefor.  At the


                                       15
<PAGE>   16
        election of any party said award may also be filed, and judgment entered
        thereon and execution issued therefor, with the clerk of one or more
        other courts, state or federal, having jurisdiction over the party
        against whom such award is rendered or its property.

        SECTION 4.12.  HEADINGS.  The headings contained in this Agreement are
for convenience only and shall in no manner be construed as a part of this
Agreement.

        SECTION 4.13.  ENFORCEMENT.  In the event either party resorts to legal
action to enforce the terms and provisions of this Agreement, the prevailing
party shall be entitled to recover the costs of such action so incurred,
including, without limitation, reasonable attorneys' fees.

        SECTION 4.14.  COUNTERPARTS.  This Agreement (and any written amendment
thereto) may be executed in one or more counterparts, each of which shall be
deemed to be an original but all of which together will constitute one and the
same instrument.

        SECTION 4.15.  SURVIVAL OF THE EXECUTIVE'S OBLIGATIONS.  The
Executive's obligations under this Agreement shall survive regardless of
whether the Executive's employment by the Company is terminated, voluntarily or
involuntarily, by the Company or the Executive, with or without cause.
