                                  ARTICLE VIII

                      NON-COMPETITION AND NON-INTERFERENCE

                  8.1 NONCOMPETITION; CONFIDENTIALITY. As an inducement to the
Company to execute this Agreement and in order to preserve the goodwill
associated with the business of the Company and in addition to and not in
limitation of any covenants contained in any agreement executed and delivered
herewith, Physician hereby covenants and agrees as follows:

                           a. COVENANT NOT TO COMPETE. During the term of this
Agreement and for a period of two (2) years after its termination "For Cause",
Physician will not directly or indirectly:

                                    (1) be employed by, engage in, continue in
or carry on any business which competes with the Business of the Company or any
business of the Acquisition Corp, MIOA or any of its subsidiaries that is
substantially similar thereto, including owning or controlling any financial
interest in any corporation, partnership, firm or other form of business
organization which is so engaged;

                                    (2) be employed by, consult with, advise or
assist in any way, whether or not for consideration, any corporation,
partnership, firm or other business organization which is now or becomes a
competitor of the Company or the Acquisition Corp in any aspect with respect to
the Business of the Company or the Acquisition Corp, including, but not limited
to, advertising or otherwise endorsing the products of any such competitor;
soliciting patients and customers or otherwise serving as an intermediary for
any such competitor; loaning money or rendering any other form of financial
assistance to or engaging in any form of business transaction on other than on
an arm's length basis with any such competitor;

                                    (3) offer employment to an employee of the
Company, MIOA or any of its subsidiaries, without the prior written consent of
MIOA; or

                                    (4) engage in any practice the purpose of
which is to evade the provisions of this covenant not to compete or to commit
any act which adversely affects the Company, the Acquisition Corp or their
business;

                  provided, however, that the foregoing shall not prohibit the
ownership of securities of corporations which are listed on a national
securities exchange or traded in the national over-the-counter market in an
amount which shall not exceed 5% of the outstanding shares of any such
corporation. The parties agree that the geographic scope of this covenant not to
compete shall extend in an outward radius of 15 miles from any clinic, lab,
medical facility or any other business of the Company, Acquisition Corp or any
similar business of any other subsidiary of MIOA. The parties agree that the
Company or the Acquisition Corp, as the case may be, may sell, assign or
otherwise transfer this covenant not to compete, in whole or in part, to any

                                      -9-
<PAGE>   10

person, corporation, firm or entity that purchases all or part of the Company's,
or the Acquisition Corp's, business. In the event a court of competent
jurisdiction determines that the provisions of this covenant not to compete are
excessively broad as to duration, geographical scope or activity, it is
expressly agreed that this covenant not to compete shall be construed so that
the remaining provisions shall not be affected, but shall remain in full force
and effect, and any such over broad provisions shall be deemed, without further
action on the part of any person, to be modified, amended and/or limited, but
only to the extent necessary to render the same valid and enforceable in such
jurisdiction.

                           b. EQUITABLE RELIEF FOR VIOLATIONS. Physician agrees
that the provisions and restrictions contained in this Section are necessary to
protect the legitimate continuing interests of the Company and MIOA and that any
violation or breach of these provisions will result in irreparable injury to the
Company and MIOA for which a remedy at law would be inadequate and that, in
addition to any relief at law which may be available to the Company and/or MIOA
for such violation or breach and regardless of any other provision contained in
this Agreement, the Company and MIOA shall be entitled to injunctive and other
equitable relief as a court may grant after considering the intent of this
Section.

                  8.2 SEVERABILITY. If any covenant or provision contained in
Article VIII is determined to be void or unenforceable in whole or in part, it
shall not be deemed to affect or impair the validity of any other covenant or
provision. If, in any arbitration or judicial proceeding, a tribunal shall
refuse to enforce all of the separate covenants deemed included in this Article
VIII, then such unenforceable covenants shall be deemed eliminated from the
provisions hereof for the purpose of such proceedings to the extent necessary to
permit the remaining separate covenants to be enforced in such proceedings.

                                   ARTICLE IX

                                  MISCELLANEOUS

                  9.1 NO WAIVERS. The failure of either party to enforce any
provision of this Agreement shall not be construed as a waiver of any such
provision, nor prevent such party thereafter from enforcing such provision or
any other provision of this Agreement.

                  9.2 NOTICES. Any notice to be given to the Company and
Physician under the terms of this Agreement may be delivered personally, by
