intentions of the parties hereto.  9.17Rights Cumulative.  The various rights and remedies herein
granted to the respective parties hereto shall be cumulative and in addition to
any other rights any such party may be entitled to under law.  The exercise of one or more rights or

Option Agreement).  C.Pursuant to the terms of Systems Option, Professional is to sell
either the assets or the stock of PC in accordance with the terms of that
certain acquisition agreement by and between PC, Professional and Successor
Physician (Acquisition Agreement).  D.In consideration for Professionals sale of PCs stock or assets
to Successor Physician, the parties desire to enter into this Agreement.  AGREEMENT  NOW,
THEREFORE, in consideration of the foregoing promises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows.  1.Professionals Covenants.  As a material inducement for Successor
Physician to acquire the stock or assets of PC from Professional and contingent
on the full and faithful performance of the obligations of the parties under
the Acquisition Agreement, for a period of twenty-four (24) months commencing
as of the date when Professional sells, hypothecates, or otherwise transfers (i) his
stock in the PC or (ii) a material portion of the assets of the PC (the Effective
Date), Professional covenants as follows:  1.1That Professional will not, directly or indirectly (whether as a
sole proprietor, partner, stockholder, director, officer, employee, independent
contractor or in any other capacity as principal or agent) (i) establish,
operate or provide professional medical services within ten (10) miles of
any location at which PC conducts business or any location at which other


professional
corporations managed by Systems as of the Effective Date conduct business; or (ii) compete
with Systems in the provision of the same services or services substantially
similar to those services provided by Systems. Professional shall be deemed to
compete with Systems if Professional provides to any medical association(s) or
group(s) of physicians within ten (10) miles of any location at which
PC conducts business during the term of this Agreement any services that are
the same or substantially similar to any services provided by Systems pursuant
to the terms of its management services agreements.  1.2That Professional will not, directly or indirectly, (whether as a
sole proprietor, partner, stockholder, director, officer, employee, independent
contractor or in any other capacity as principal or agent) (i) hire or
induce any party to recruit or hire any person who is an employee or
independent contractor of PC or Systems or any of their affiliates; (ii) whether
for himself or any other person or entity, call upon, solicit, divert or take
away, or attempt to solicit, call upon, divert or take away any customers,
business or clients of PC or Systems or their affiliates (including, without
limitation, any third party payors); (iii) solicit, or induce any party to
solicit, any contractors of PC or Systems or their affiliates, to enter into
the same or a similar type of contract with any other party; (iv) for
himself or for any other entity, solicit, divert or take away or attempt to
solicit, divert or take away any of PCs patients; or (v) disrupt, damage,
impair or interfere with the business of PC or Systems or their affiliates.  These
covenants on the part of Professional shall be construed as an agreement
independent of any other provision in this Agreement; and the existence of any
claim or cause of action of Professional against PC or Systems, whether
predicated on this Agreement or otherwise, shall not constitute a defense to
the enforcement by PC or Systems of these covenants.  It
is agreed by the parties hereto that if any portion of the covenants specified
in subparagraphs 1.1 and 1.2 above are held to be unreasonable, arbitrary or
against public policy, the covenants herein shall be considered divisible both
as to time and geographic area; and each month of the specified period shall be
deemed a separate period of time, and each quarter mile shall be deemed a
separate geographic area so that the lesser period of time or geographic area
shall remain effective as along as the time or geographic area are not
unreasonable, arbitrary, or against public policy.  The parties hereto agree that, in the event
any court determines the specified time period or the specified geographic area
to be unreasonable, arbitrary or against public policy, a lesser time period or
geographic area which is determined to he reasonable, nonarbitrary and not
against public policy may be enforced against Professional, where such
provisions shall be deemed reformed to the maximum time or geographic or other
limitations permitted by applicable law, as determined by such court in such
action.  The
parties agree that the remedy at law for any breach of such covenant or of the
related covenants set forth herein would be inadequate, and that therefore PC,
Systems or any other person entitled to enforce such covenants shall be
entitled to seek injunctive relief thereon in addition to its rights to
monetary damages.  2.Confidentiality  2.1PCs Confidential and Proprietary Information.  In the course of
Professionals engagement by PC, Professional has had access to certain
confidential or proprietary information


relating
to the patients and operations of PC including, without limitation, patient
lists, training material, brochures, practice development aids, techniques and
other trade secrets, which information will become the confidential and
proprietary information of PC (collectively, the PCs Confidential and
Proprietary Information).  Professional
shall maintain all of PCs Confidential and Proprietary Information in the
strictest confidence and shall not directly or indirectly use such information
at any time, or divulge any of PCs Confidential and Proprietary Information at
any time to any third parties, other than (i) PC, Systems or their
respective representatives who have a reasonable need for such information and
who have similarly agreed to hold such information in confidence, without the
express prior written consent of PC; (ii) as may be reasonably necessary
in connection with any litigation or dispute in relation to Professionals
prior operation of the practice through Practice; or (iii) upon court
order to do so.  Professional shall not
remove from any of PCs practice sites or make copies or other reproductions of
any of PCs Confidential and Proprietary Information without the express prior
written consent of PC. Upon the Effective Date of this Agreement, Professional
shall immediately return any and all original documents and materials
containing any of PCs Confidential and Proprietary Information, including any
and all copies or other reproductions thereof, to PC.  2.2Systems Confidential and Proprietary Information.  2.2.1Professional recognizes the proprietary interest of Systems in any
of Systems Confidential and Proprietary Information (as hereinafter defined).
Professional acknowledges and agrees that any and all Confidential and
Proprietary Information of Systems communicated to, learned of, or otherwise
acquired by Professional in the course of Professionals engagement by the PC
shall be the property of Systems. 
Professional further acknowledges and understands that Professionals
use or disclosure of Systems Confidential and Proprietary Information will
result in irreparable injury and damage to Systems.  As used herein, Systems Confidential and
Proprietary Information means all trade secrets and other confidential and/or
proprietary information of Systems and its affiliates, including information
derived from reports, investigations, research, work in progress, codes,
marketing and sales programs, financial projections, costs summaries, pricing
formula, contract analysis, financial information, projections, confidential
filings with any state or federal agency, and all other confidential concepts,
methods of doing business, ideas, materials or information (other than the PCs
patient records) of Systems whether prepared for, by or on behalf of Systems or
its employees, officers, directors, agents, representatives, or consultants.  2.2.2Professional acknowledges and agrees that Systems is entitled to
prevent the disclosure or improper use of any of Systems Confidential and
Proprietary Information.  Professional
agrees at all times to hold in strictest confidence and not to disclose to any
person, firm or corporation and not to use, except in the pursuit of the
business of PC or Systems, Systems Confidential and Proprietary Information,
without the prior written consent of Systems; unless (i) such information
becomes known or available to the public generally through no wrongful act of
Professional or (ii) disclosure is required by law or the rule, regulation
or order of any governmental authority under color of law; provided, that prior
to disclosing any of Systems Confidential and Proprietary Information pursuant
to this clause (ii), Professional shall, if possible, give prior written notice
thereof to Systems and provide Systems with the opportunity to contest such
disclosure.  Professional shall take all
necessary and proper


precautions
against disclosure of any of Systems Confidential and Proprietary Information
to unauthorized persons.  Upon execution
of this Agreement, Professional shall cease all use of any of Systems
Confidential and Proprietary Information and shall execute such documents as
may be reasonably necessary to evidence abandonment of any claim thereto.  2.2.3Upon the execution of this Agreement, and at any time upon the
request of Systems, Professional will promptly deliver or cause to be delivered
to Systems all documents, data and other information in their possession that
contains or is related to any of Systems Confidential and Proprietary
Information regarding Systems or its affiliates.  Professional shall not take or retain any
documents or other information, or any reproduction or excerpt thereof,
containing any of Systems Confidential and Proprietary Information.  3.Professionals Representation.  Professional specifically acknowledges,
represents, and warrants that (i) each of Professionals covenants set
forth in this Agreement are being made in connection with the Acquisition
Agreement; (ii) such covenants are reasonable and necessary to protect the
legitimate interests of Systems, PC and their respective affiliates; and (iii) Successor
Physician would not have entered into the Acquisition Agreement in the absence
of such restrictions.  4.Miscellaneous.  4.1Successors and Assigns.  This Agreement shall be binding upon and
shall inure to the benefit of the parties and their respective heirs (as
applicable), legal representatives, and permitted successors and assigns.  No party may assign this Agreement or the
rights, interests or obligations hereunder; provided, however, each of Systems
and PC may assign any or all of its respective rights and interests hereunder
to one or more of its respective affiliates. Any assignment in contravention of
this Section shall be null and void.  4.2Counterparts.  This Agreement, and any amendments thereto,
may be executed in counterparts, each of which shall constitute an original
document, but which together shall constitute one and the same instrument.  4.3Headings.  The section headings contained in this
Agreement are inserted for convenience only and shall not affect in any way the
meaning or interpretation of this Agreement.  4.4Amendment.  This Agreement may not be amended except by a
writing executed by all parties.  4.5Time of Essence.  Time is expressly made of the essence of this
Agreement and each and every provision hereof of which time of performance is a
factor.  4.6Notices.  Any notices required or permitted to be given
hereunder by any party to the other shall be in writing and shall be deemed
delivered upon personal delivery; twenty-four (24) hours following deposit with
a courier for overnight delivery; or five (5) days following deposit in
the U.S. Mail, registered or certified mail, postage prepaid, return-receipt
requested, addressed to the parties at the following addresses or to such other

  to Successor Physician:  4.7Governing Law.  This Agreement shall be governed by and
construed in accordance with the laws of the State of California without
reference to the conflict of laws provisions thereof.  4.8Injunctive Relief.  The parties hereto acknowledge and agree that
a breach by Professional of this Agreement will cause irreparable damage to
Systems or PC, as applicable, the exact amount of which will be difficult to
ascertain, and that remedies at law for any such breach will be
inadequate.  Accordingly, Professional
agrees that if Professional breaches this Agreement, then Systems and PC, as
appropriate, shall be entitled to injunctive relief, and Professional agrees
not to assert in any proceeding that Systems or PC, as applicable, has an
adequate remedy at law.  Professional
shall pay the reasonable fees and expenses, including attorneys fees, incurred
by Systems, PC or any successor or assign in enforcing this Agreement.  4.9Severability.  If any provision or portion of this Agreement
is held by a court of competent jurisdiction to be invalid or unenforceable,
the remainder of this Agreement will nevertheless continue in full force and
effect and shall not be invalidated or rendered unenforceable or otherwise
adversely affected, unless such invalidity or unenforceability would defeat an
essential business purpose of this Agreement. 
Without limiting the generality of the foregoing, if the provisions of
this Agreement shall be deemed to create a restriction, which is unreasonable
as to either duration or geographical area or both, the parties agree that the
provisions of this Agreement shall be enforced for such duration and in such
geographic area as any court of competent jurisdiction may determine to be
reasonable.  4.10Attorneys Fees.  Should any of Systems, PC or Professional
institute any action or procedure to enforce this Agreement or any provision
hereof, or for damages by reason of any alleged breach of this Agreement or of
any provision hereof, or for a declaration of rights hereunder (including
without limitation arbitration), the prevailing party(ies) in any such action


or
proceeding shall be entitled to receive from the other party all costs and
expenses, including without limitation reasonable attorneys fees, incurred by
the prevailing party(ies) in connection with such action or proceeding.  4.11Professionals Practice of Medicine.  Notwithstanding anything to the contrary in
this Agreement, nothing herein is meant to limit or restrict Professionals
ability to practice medicine as a physician within any radius, including within
10 miles of any PC location, in the State of California.   [The remainder of the page is
