         2.5      ROLE OF SPECIAL MONITOR AFTER CONFIRMATION OF PLAN OF
REORGANIZATION; RECONSTITUTED CREDITORS' COMMITTEE. Upon the Plan of
Reorganization Effective Date, the role of the Special Monitor-Examiner of MPN
and the California Operations as to MTN Provider Claims shall automatically
terminate without any further acts by any Person. As of such date, the Special
Monitor-Examiner shall cease to perform the functions described in Section 2.2
hereof. Upon the Plan of Reorganization Effective Date, the Committee shall be
reconstituted as the Reconstituted Committee as provided for in the Plan of
Reorganization and shall have such rights and duties as provided in the Plan of
Reorganization in addition to the rights and duties of


                                       14

the Creditors' Committee hereunder. Each Consenting Plan shall be entitled to
exercise any right of enforcement that it may have under Section 16.14,
notwithstanding any provision of this Agreement providing for notice to or
action by the Special Monitor-Examiner. Without limiting the generality of the
foregoing, nothing in Section 3.8(d) hereof or any other provision concerning
the rights and powers of the Special Monitor-Examiner shall affect or impede any
Consenting Plan's right to enforce this Agreement under Section 16.14.

MPN's interest in the California Operations, subject to the provisions of the
Bankruptcy Code and the jurisdiction of the Bankruptcy Court. Set forth on
Schedule 3.1 are key elements of the Transition Plan as of the Amended Agreement

         3.2      MANAGEMENT AGREEMENT. The Management Agreement shall be
amended, effective as of March 12, 1999, substantially in the form set forth on
Schedule 3.2. Nothing in this Section or in the amendment to the Management
Agreement shall be construed to be an assumption of the Management Agreement by
MPN; and MPN expressly reserves the right to assume or reject the Management
Agreement and any and all rights it may have in connection with any such
assumption or rejection.

         3.3      PAYMENTS TO MANAGED PHYSICIAN PRACTICES. MPN shall pay
capitation amounts owed to the Managed Physician Practices on the first Business
Day of the month for which the capitation payment applies, or the first Business
Day after MPN has sufficient funds to make such payment, but otherwise in
accordance with the terms of the underlying capitation agreements with the
Managed Physician Practices.

         3.4      DISPOSITION OF THE CALIFORNIA OPERATIONS.

                  (a)      Schedule 3.4(a) identifies as of the Agreement Date
the portion of the California Operations that are the subject of pending sale
agreements, the subject of letters of intent and the anticipated closing date of
such sales, and identifies the remainder of the California Operations to be sold

                  (b)      The Net Cash Proceeds of the sale of the California
Operations shall be deposited in the California Accounts on the date each sale
closes and the dates on which such Proceeds are received in accordance with the
agreement of the parties to the sale. The Net Cash Proceeds from the sales shall
be allocated between the California Accounts in accordance with the terms of the
stipulation entered into in the Bankruptcy Case with respect to the allocation
to MPN.

an MPN Plan Release, and (B) the total amount of all Plan Preserved Claims with

in each case, to the extent that:

                           (xii)    Revenues received by MPN and the Managed

                           (xxi)    As to MPN, ordinary and necessary operating

                  (b)      Timing of Payments. Pursuant to the MedPartners
Funding Commitment, MedPartners shall cause Provider Claims to be timely
adjudicated and, to the extent determined to be valid, timely paid. For purposes
of this Section, timely adjudication and timely payment shall mean (provided,
for the first thirty days of the Agreement, the timely standard will be deemed
to be complied with if MedPartners has implemented a procedure acceptable to the
Special Monitor or Special Monitor-Examiner, as the case may be, for payments to
become current):

                           (1)      with respect to a Managed Physician Practice
Provider Claim, such Claim shall be adjudicated and, to the extent determined to
be valid and after giving effect to any offset or recoupment, paid in accordance
with applicable law, including California Health and Safety Code ss. 1371,
upon receipt by MedPartners and the applicable Managed Physician Practice of the
MPPP Release; provided, however, that MedPartners shall have mailed or otherwise
transmitted the MPPP Release to each holder of a Managed Physician Practice
Provider Claim within three Business Days after MedPartners receives the
approval by the Creditors Committee of the form of the MPPP Release.

                           (2)      with respect to a pre-petition MPN Provider
Claim, such Claim shall be adjudicated and, to the extent determined to be an
Allowed MPN Claim and after giving effect to any offset or recoupment, timely
paid, in a manner that is consistent with the Bankruptcy Code if the Bankruptcy
Case is then pending and the Plan of Reorganization upon receipt by MedPartners
and MPN of the MPN Provider Release; and

                           (3)      with respect to a post-petition MPN Provider
Claim, such Claim shall be adjudicated and, to the extent determined to be an
Allowed MPN Claim after giving effect to any offset or recoupment, timely paid,
in a manner that is consistent with the Bankruptcy Code if the Bankruptcy Case
is then pending, and if such Claim is being paid pursuant to the MedPartners
Funding Commitment, upon receipt by MedPartners and MPN of the MPN Provider
Release.

The rights of each holder of a Managed Physician Practice Provider Claim or an
MPN Provider Claim with respect to the MedPartners Funding Commitment shall
constitute an unsecured Claim against MedPartners under this Agreement if such
holder is a Consenting Provider.

                  (c)      Funding.

                           (1)      As a part of the MedPartners Funding
Commitment, as soon as possible following the Plan of Reorganization Effective
Date, MedPartners shall cause Bank of America (the "Lender") to issue an
irrevocable letter of credit in the amount of $38 million in favor of MPN, which
shall substantially be in the form attached hereto as Schedule 3.5(c-1) (the
"MPN Letter of Credit"). If the Lender fails to provide notice of renewal of the
MPN Letter of Credit on or before the tenth business day prior to the then
current Stated Expiration Date (as defined in the MPN Letter of Credit),
MedPartners shall have the right to replace the MPN Letter of Credit with a new
letter of credit issued by a lender reasonably acceptable to the Reconstituted
Committee. If this Agreement terminates, MPN agrees to provide notice of such
termination to the Lender pursuant to the terms of the MPN Letter of Credit
within five (5) Business Days of such termination. MPN also agrees to provide
the


                                       17
<PAGE>   23

Lender with any other certification or documentation reasonably required
pursuant to the terms of the MPN Letter of Credit or any replacement or renewal
letter of credit. The funds made available to MPN under the MPN Letter of Credit
shall be used to pay MPN Provider Claims of Consenting Providers and Consenting
Plans and Plan Preserved Claims of Consenting Plans that become Allowed MPN
Claims and are subject to the MedPartners Funding Commitment as they become
payable after giving effect to all valid offsets and recoupments. To the extent
MPN Provider Claims held by Consenting Providers are not paid from the MPN
Letter of Credit, MedPartners shall fulfill the MedPartners Funding Commitment
with respect to such MPN Provider Claims in accordance with Section 3.5(b) above
and the Plan of Reorganization. To the extent MPN Provider Claims and MPN Plan
Preserved Claims held by Consenting Plans that are payable in accordance with
this Agreement and the Supplemental Plan Agreement are not paid from the
proceeds of the MPN Letter of Credit, they shall be payable as provided in
Section 3.5(f) below and the Plan of Reorganization. All allowed Plan Preserved
Claims and allowed MPN Provider Claims held by Consenting Plans that execute the
MPN Plan Release and that are not paid after exhaustion of the proceeds of the
MPN Letter of Credit shall be subject to the MedPartners Funding Commitment and
shall be paid in accordance with and subject to the Plan of Reorganization and
the Supplemental Plan Agreement, as modified by any other agreement between MPN
and a Consenting Plan that has been approved by final order of the Bankruptcy
Court.

                           (2)      As part of the MedPartners Funding
Commitment, as soon as possible following the Plan of Reorganization Effective
Date, MedPartners shall cause the Lender to issue an irrevocable letter of
credit in the amount of $2 million, which shall be substantially in the form
attached hereto as Schedule 3.5(c-2) (the "MPP Letter of Credit"). MedPartners
agrees to replace the MPP Letter of Credit on or before its stated expiration
date with a replacement letter of credit in the then current stated amount which
shall have substantially similar drawing terms and conditions and a stated
expiration date which is the date one year from the Plan of Reorganization
Effective Date. The funds made available under the MPP Letter of Credit shall be
used to pay Managed Physician Practice Provider Claims of Consenting Providers
and Consenting Plans that execute a Managed Physician Practice Plan Release and
Managed Physician Practice Plan Preserved Claims of Consenting Plans and that
are subject to the MedPartners Funding Commitment.

                  (d)      Excess Funds.

                           (1)      In the event the amount deposited into the
applicable California Account hereunder materially exceeds the funds, as
determined by an actuary or financial consultant satisfactory to the parties
hereto or as otherwise agreed by the parties hereto, necessary to fulfill the
MedPartners Funding Commitment, the excess funds will be returned to
MedPartners promptly upon the occurrence of the following:

                                    (A)      as to the MPN California Account,
at any time after March 31, 2000, when the Bankruptcy Court, upon notice and
hearing, has confirmed the determination of excess funds; and


                                       18
<PAGE>   24

                                    (B)      as to the MedPartners California
Account, when the Special Monitor-Examiner, upon five Business Days written
notice of such determination to the Creditors Committee, has determined the
amount of excess funds.

                           (2)      In the event the MedPartners Funding
Commitment has been satisfied with respect to Provider Claims and Plan Preserved
Claims, and there are excess funds in either of the California Accounts any such
excess shall not be subject to withdrawal as excess funds and shall be used to
satisfy Provider Claims and Plan Preserved Claims otherwise payable from the
other California Account.

                           (3)      All funds remaining in either California
Account will be returned promptly to MedPartners upon the occurrence of the
following:

                                    (A)      as to the MPN California Account,
when the MedPartners Funding Commitment with respect to MPN Provider Claims and
Plan Preserved Claims against MPN has been fully satisfied and there are
adequate funds in the MedPartners California Account to fulfill the MedPartners
Funding Commitment; and

                                    (B)      as to the MedPartners California
Account, when the MedPartners Funding Commitment with respect to the Managed
Physician Practice Provider Claims and Plan Preserved Claims against the Managed
Physician Practices has been fully satisfied.

                           (4)      For purposes of this Section 3.5(d):

                                    (A)      The MedPartners Funding Commitment
with respect to MPN Provider Claims and Plan Preserved Claims against MPN shall
be deemed fully satisfied when an order of the Bankruptcy Court has been entered
making such finding, following notice and hearing; and

                                    (B)      The MedPartners Funding Commitment
with respect to the Managed Physician Practice Provider Claims and Plan
Preserved Claims against Managed Physician Practices shall be deemed satisfied
upon the expiration of five Business Days after the Special Monitor-Examiner
gives the Creditors Committee written notice thereof.

                  (e)      Certain Event. In the event that MedPartners shall
not have executed by July 1, 1999 agreements to sell the practice assets related
to Southern California Medical Corporation, a California professional
corporation, Talbert Medical Group, a California professional corporation, or
Mullikin Practice Group, a Medical Corporation, or any such sale shall not have
been consummated on or before July 31, 1999, MedPartners shall notify the State
of such event on or after July 1, 1999, and MedPartners may begin an orderly
termination of such operations provided that such operations shall continue for
a minimum of 60 days from such notice. In such event, any Claims arising after
giving such notice, shall not be considered to be Provider Claims and shall not
be subject to the MedPartners Funding Commitment. In the event MedPartners gives
a notice with respect to a practice asset under this Section, the State has
consented to the Plans promptly moving their members to unaffiliated networks.
Notwithstanding anything to the contrary in this Agreement, to the extent any
Plan moves any enrollees based on the closure of any Managed Physician Practice,
the Plans shall use their best efforts to move


                                       19
<PAGE>   25

their enrollees to unaffiliated networks with capacity sufficient to provide
uninterrupted Health Care Services to their enrollees. In addition, the Plans
shall acknowledge their obligations under the Knox-Keene Act to provide, and
shall agree to provide, available and accessible health care services to their
members consistent with the requirement of continuity of care under the
Knox-Keene Act when the enrollees have been moved to the unaffiliated networks.
Without limiting the generality of the foregoing, the movement of members may be
undertaken without regulatory filings or approvals, provided that the Plans
shall simultaneously send a letter to the State advising the State of such
actions. As soon as reasonably practicable thereafter, the Plans will file
appropriate regulatory documents. Further, if MedPartners gives notice under
this Section concerning termination of operations, MedPartners, the Managed
Physician Practices and their respective affiliates shall take reasonable steps
to (i) assist the Plans in the transfer of enrollees to unaffiliated providers
in accordance with the Health Care Services Agreements and applicable law, and
(ii) carry out the orderly termination of such operations so as not to
unreasonably increase the Plans and their enrollees' damages associated with
termination of operations, and any such expenses incurred by MedPartners
pursuant to this Section shall not reduce the MedPartners Funding Commitment.

                  (f)      Timing of Payment of Plan Preserved Claims. With
respect to each Consenting Plan and pursuant to the MedPartners Funding
Commitment, MedPartners shall cause Plan Preserved Claims and Provider Claims
that are subject to the MedPartners Funding Commitment held by Consenting Plans
to be paid in accordance with the Supplemental Plan Agreement, as amended or
supplemented from time to time or the terms and conditions of any agreement
between MedPartners and such Consenting Plan that modifies the Supplemental Plan
Agreement as to those parties or between MPN and such Consenting Plan that
modifies the Supplemental Plan Agreement as to those parties and has been
approved by Final Order of the Bankruptcy Court.

         3.6      INTENTIONALLY LEFT BLANK.

         3.7      NEGATIVE ASSURANCES.

                  (a)      No Liens. Nothing herein is intended, or shall be
construed, to grant to the State or any other Person any security interest,
encumbrance, assignment, deposit arrangement, lien (statutory or other) or
preference, priority, or other security or similar agreement, or preferential
arrangement of any kind or nature whatsoever, in respect of any assets of
MedPartners, MPN or any other subsidiary of MedPartners, or any agreement to
give or grant any of the foregoing. This Agreement shall not constitute a bond,
note, debenture or similar instrument for the payment of money, and the
obligations of MedPartners and MPN hereunder are not debt for borrowed money.

                  (b)      No Occurrences. Nothing is intended, or shall be
construed to constitute the occurrence of any of the following events: (i) the
entry of a judgment, decree or order by a court having jurisdiction in the
premises granting relief under the Bankruptcy Code, adjudicating MedPartners to
be insolvent, or approving as properly filed a petition seeking reorganization
or liquidation of MedPartners under the Bankruptcy Code or any similar
applicable Federal or State law; (ii) the entry of a judgment, decree or order
by a court having jurisdiction in the premises for the appointment of a receiver
or liquidator or trustee or assignee in bankruptcy or insolvency


                                       20
<PAGE>   26

of MedPartners or of its property, or for the winding up or liquidation of its
affairs; or (iii) the filing by MedPartners of a petition for relief under the
Bankruptcy Code; the consent by MedPartners to the filing of a bankruptcy
proceeding against it; the filing by MedPartners of a petition or answer or
consent seeking reorganization or liquidation under the Bankruptcy Code or any
similar applicable Federal or State Law, or the consent by MedPartners to the
filing of any such petition; or the consent by MedPartners to the appointment of
a receiver or liquidator or trustee or assignee in bankruptcy or insolvency of
it or of its property; or the making by MedPartners of an assignment for the
benefit of creditors; or an admission by MedPartners of its inability to pay its
debts generally as they become due.

         3.8      PROCEDURES FOR PROVIDER CLAIMS.

                  (a)      Independent Claims Oversight. MedPartners shall
appoint the Claims Monitor, subject to the supervisory oversight of the Special
Monitor-Examiner, to assist MedPartners and the holders of Provider Claims to
(i) determine the amounts of the Provider Claims and advances by MPN to such
holders and (ii) resolve disputes related thereto. The Special Monitor-Examiner
shall oversee the activities of the Claims Monitor and MPN with respect to the
Provider Claims. In connection with the dispute resolution process with respect
to the MPN Provider Claims, MPN may exercise its rights under the Bankruptcy
Code. Any Managed Physician Practice Provider Claims not fully resolved in
accordance with this procedure shall be resolved through the ordinary course of
adjudication under the applicable agreements.

                  (b)      MPN Bar Date. As soon as reasonably practicable after
the Agreement Date, MPN shall file a motion with the Bankruptcy Court seeking to
establish a bar date of July 31, 1999 (or the first date thereafter as may be
ordered by the Bankruptcy Court) for the filing of all pre-petition Claims. All
objections to pre-petition Claims, other than any pre-petition Claim (1)
asserted by any Plan, or (2) that is the subject of a settlement agreement
agreed to by the claimant, shall be filed by May 1, 2000; provided, however,
that the Creditors Committee shall have the right to file objections to
pre-petition Claims through the Plan of Reorganization Effective Date or such
other date as is provided for in the Plan of Reorganization once confirmed. As
soon as practicable, MPN shall file a motion with the Bankruptcy Court seeking
to establish a bar date of October 31, 1999 for all post-petition Claims with
dates of service before August 1, 1999 other than administrative expense
priority claims of professional persons against MPN. The Special
Monitor-Examiner may file a pleading in support of such motion. The parties
shall agree on the establishment of a subsequent bar date for services performed
or goods provided after August 1, 1999. Unless the Bankruptcy Order orders
otherwise for cause shown, the subsequent bar date shall be no later than
November 30, 1999.

                  (c)      Managed Physician Practice Bar Date. As soon as
reasonably practicable after the Agreement Date, MedPartners shall provide a
notice to all parties (including, without limitation, the Plans) known to
MedPartners to have, or who might reasonably assert, Managed Physician Practice
Provider Claims to establish a bar date of October 31, 1999 for the filing of
all Claims against the Managed Physician Practices and informing such holders
that failure to file Claims prior to such bar date will preclude satisfaction of
such Claims pursuant to the terms of this Agreement.


                                       21
<PAGE>   27

                  (d)      Special Monitor-Examiner Supervision. The Special
Monitor-Examiner shall supervise MPN and MedPartners' compliance with their
obligations under Section 3.5(b) to adjudicate timely and pay timely Provider
Claims, and shall supervise the Claims Monitor in the performance of its duties.
Among his other duties, the Special Monitor-Examiner shall review compliance
with Section 3.5(b) not less frequently than biweekly. In the event the Special
Monitor-Examiner determines that MPN and MedPartners are not in compliance with
the obligations to adjudicate timely and pay timely Provider Claims, he or she
shall give prompt written notice of that determination to MPN, MedPartners, the
DOC and the Creditors Committee. Upon receipt of such notice, MPN, with respect
to MPN Provider Claims, and MedPartners, with respect to Managed Physician
Practice Provider Claims, shall have five Business Days to initiate procedures
to cure any alleged failure to comply with its obligation to adjudicate timely,
and three Business Days to cure any alleged failure to comply with its
obligation to pay timely. If, at the conclusion of the applicable period, the
Special Monitor-Examiner determines that MPN or MedPartners, as the case may be,
has not adequately commenced to cure the alleged failure, the Special
Monitor-Examiner, as his or her sole remedy, may initiate final and binding
arbitration pursuant to the provisions of Section 12, regarding such alleged
failure. If a Representative of one or more eligible Beneficiaries under Section
16.14 makes written demand upon the Special Monitor-Examiner to make a
determination of non-compliance pursuant to this Section 3.8(d), and the Special
Monitor-Examiner fails to make such a determination within ten Business Days
following receipt of such notice or determines that there is compliance, then
such Representative may give written notice of such Beneficiaries' assertion of
an alleged failure to comply to MPN, MedPartners, the State and the Creditors
Committee. If, at the conclusion of the same five and three Business Day periods
following receipt of such notice to address such alleged non-compliance that
would apply following written notice by the Special Monitor-Examiner, such
Beneficiaries determine that MPN or MedPartners, as the case may be, has not
adequately commenced to cure the alleged failure, the Representative, as his,
her or its sole remedy, may initiate final and binding arbitration pursuant to
the provisions of Section 12 regarding such alleged failure.

         3.9      RELINQUISHMENT OF LICENSE OF MPN. As soon as reasonably
practicable and subject to applicable provisions of the Bankruptcy Code and
California Health and Safety Code ss. 1399, MPN's health care service plan
license shall be surrendered when MPN no longer has institutional risk and when
approved by DOC and the Bankruptcy Court.

         4.1      ORGANIZATION. MedPartners is duly organized and existing and

qualified and licensed to do business in, and in good standing in, all states
except where the failure to be so licensed or qualified reasonably could be
expected to constitute a Material Adverse Change.

"Default") by MedPartners under this Agreement:

                  (a)      Except as set forth in Section 10.1(b) or (c)
below, the failure of MedPartners to perform, in any material respect, the
obligations required to be performed by it under this Agreement; provided,
however, that a determination by the Special Monitor-Examiner under Section
3.8(d), or the initiation of any arbitration by any Representative under Section
12, shall not constitute the failure by MedPartners to perform its obligations
hereunder, in any material respect, but (1) MedPartners' failure to pay the
amount of any arbitration award under Section 12 (including an award obtained
pursuant to the procedure set forth in Section 16.14) by reason of such
determination or arbitration within five Business Days of such award; or (2) the
nonpayment of (i) a Final Preserved Claim in favor of a Consenting Plan in
accordance with the provisions of the Supplemental Plan Agreement and the Plan
of Reorganization or (ii) with respect to a Claim covered by the MedPartners
Funding Commitment held by a Consenting Plan that may be entitled to any
distribution pursuant to, and in accordance with, the terms and conditions of
any agreement between MedPartners and such Consenting Plan that modifies the
Supplemental Plan Agreement as to those parties or between MPN and such
Consenting Plan that modifies the Supplemental Plan Agreement as to those
parties and has been approved by Final Order of the Bankruptcy Court, shall
constitute a Default hereunder.

                  (b)      The failure by MedPartners or MPN to comply with the
provisions of Sections 3.4(b) or the failure by MedPartners or MPN to permit the

not be deemed to have failed to make a payment or to have satisfied any
obligations, where such failure would constitute a Default, during the period
that MedPartners or MPN, as applicable, is adjudicating in good faith the nature
or amount of the payment or obligation, provided that MedPartners shall fulfill
the MedPartners Funding Commitment in connection with any portion of any
Provider Claim or Plan Preserved Claim that is not contested or subject to a
setoff or recoupment asserted in good faith; provided, however, to the extent
any obligation of MedPartners under this Agreement is contingent upon
performance by any third party, including satisfaction of any condition
precedent to the effectiveness of this Agreement, it shall not be a Default
hereunder if MedPartners fails to complete such obligation despite good faith
efforts to do so, by reason of such third party's non-performance.


                                       28
<PAGE>   34

State believes that MedPartners is in Default, the Special Monitor-Examiner or
the State shall provide MedPartners with written notice of the alleged
violation, specifying the section of this Agreement that MedPartners has
allegedly violated, and specifically identifying the act, omission, event,
occurrence, incident, circumstance or other conduct of MedPartners that the
Special Monitor-Examiner or the State believe constitutes the Default.
MedPartners shall have 20 Business Days in the case of a Default of the type set
forth in Section 10.1(a) and three Business Days in the case of a Default of
the type set forth in Section 10.1(b) or 10.1(c) to cure such Default. In the
event the Default is not cured after such period, the State may exercise the
remedies set forth in Section 10.3.

         10.3     APPLICATION TO STATE COURT. In the event MedPartners does not

the case or the referee, if any, assigned to the case as to whether a Default
has occurred and remains uncured. The expedited procedures pursuant to
California Code of Civil Procedure Section 664.6 shall apply to such motion.
Such motion may be brought on an ex parte basis under and pursuant to the Los
Angeles Superior Court Local Rules then in effect provided that the moving party
shall provide MedPartners three Business Days' advance notice. The Court's
ruling on such motion shall not be executable as a money judgment until such
time as the Court enters the stipulated judgment provided for in Section 10.4,
at which time the Court will be deemed to have entered the final judgment in the
action that is subject to the right of appeal pursuant to Code of Civil
Procedure, Section 904.1. Either party may appeal the judicial determination

posted.

Court that a Default has occurred, the State may file the stipulated judgment in

on behalf of the State to carry out the terms of this Agreement, exercising the
remedies available to a judgment creditor with respect to MedPartners' assets,
and pursuing any other remedies provided by law or equity.


11.  DEFAULT BY THE STATE.


         11.1     DEFAULT. The failure of the State to perform, in any material
respect, the obligations required to be performed by it under this Agreement
after twenty days written notice and opportunity to cure shall constitute a
default by the State ("Default"); provided, however, to the extent any
obligation of the State under this Agreement is contingent upon performance by
any third party, including satisfaction of any condition precedent to the
effectiveness of this Agreement, it shall not be a Default hereunder if the
State fails to complete such obligation despite good faith efforts to do so, by
reason of such third party's non-performance.

         11.2     NOTICE OF DEFAULT. If MedPartners or MPN believes that the
State or the Special Monitor-Examiner is in Default, MedPartners or MPN shall
provide the State and the Special Monitor-Examiner with written notice of the
alleged violation, specifying the section of this Agreement that the State or
Special Monitor-Examiner has allegedly violated, and specifically


                                       29
<PAGE>   35

identifying the act, omission, event, occurrence, incident, circumstance or
other conduct of the State or the Special Monitor-Examiner that MedPartners or
MPN believes constitutes the Default. In the event the Default is not cured
after the cure period, MedPartners or MPN may exercise the remedies set forth in
Section 11.3.

         11.3     APPLICATION TO STATE COURT. In the event the State or the
Special Monitor-Examiner does not cure any alleged Default within the time
period set forth in Section 11.2, MedPartners or MPN may file a motion with the
Los Angeles Superior Court seeking a judicial determination by the judge
assigned to the case or the referee, if any, assigned to the case as to whether
a Default has occurred and remains uncured. The expedited procedures pursuant to
California Code of Civil Procedure Section 664.6 shall apply to such motion.
Such motion may be brought on an ex parte basis under and pursuant to the Los
Angeles Superior Court local rules then in effect provided that the moving party
shall provide the State and the Special Monitor-Examiner three Business Days'
advance notice. Any party may appeal the judicial determination provided that a
bond, in the amount equal to two times the amount in dispute, is posted.

         11.4     REMEDIES. Upon determination by the Los Angeles Superior Court
that a Default has occurred, MedPartners and MPN may exercise all remedies that
they may have at law or equity. Additionally, if the Default is a seizure of
assets of MPN or MedPartners with respect to the California Operations which is
determined to be either unlawful or is a Default under this Agreement, the
MedPartners Funding Commitment shall be reduced by an amount as determined by
the court equal to the impairment in MedPartners' ability to fulfill the
MedPartners Funding Commitment and all assets improperly seized shall be
returned to MedPartners or MPN, as the case may be.

12.  ALTERNATIVE DISPUTE RESOLUTION.

         12.1     DISPUTES. Any controversy, dispute, or claim in connection
with, or in relation to the interpretation or performance of Section 3.5(b) of

procedures shall be governed by the rules of the American Arbitration
Association unless inconsistent with this Section 12. The arbitrator shall
notice hearings at least five days in advance, shall permit parties to brief
issues, introduce documents, present oral testimony of witnesses, cross-examine
witnesses, and present opening and closing argument. To the extent not otherwise
provided in this Agreement, or by law, all other matters relating to the
governance of the arbitration shall be within the arbitrator's discretion. As
used in this Section 12, "party" means party to the controversy, dispute, or
claim.

         12.2     INITIATION OF ARBITRATION. Any party or, in accordance with
Section 16.14(b), a Representative may initiate arbitration by giving the other
party a written demand for arbitration pursuant to the notice requirements of

reasonable time after the claim or dispute has arisen. Within five Business Days

response on the


                                       30
<PAGE>   36


demanding party in accordance with Section 15. The demand for arbitration shall
contain a statement of the demanding party's position as to the matter or
matters in dispute, the amount of the claim, and the remedy sought. The response
shall contain a statement of the responding party's positions as to the matter
or matters in dispute, and any defenses the responding party intends to assert
in response to the demanding party's claim. Additionally, the response shall
state any cross-complaint the respondent intends to assert in the arbitration
against the initiating party, the cross-complainant's position as to the matter
or matters in dispute, the amount of the claim, and the remedy sought. The party
initiating the arbitration shall have five Business Days to respond to the
cross-claims.

         12.3     ARBITRATOR. The arbitration shall be conducted and determined
by a sole arbitrator. The arbitrator shall be Justice Campbell Lucas, or if he
is unavailable, an individual selected by Justice Lucas, or if no individual is
selected by Justice Lucas within five Business Days, the arbitrator shall be
selected by agreement of the parties; if the parties cannot so agree within five
Business Days, then the arbitrator shall be selected by the Presiding Judge of
the Los Angeles Superior Court. Any party may request such judge to designate
the arbitrator.

         12.4     COSTS OF ARBITRATION; ATTORNEYS' FEES. The costs of the
arbitration shall be shared equally by the parties. The prevailing party in the
arbitration proceeding and in any legal proceedings relating to the arbitration
shall be entitled to recover reasonable attorneys' fees and costs.

         12.5     TIMING.

                  (a)      The parties desire a speedy resolution of any
disputes that may arise. To that end, the arbitrator will, on his or her
appointment, consult with the parties to discuss a reasonable hearing schedule.

                  (b)      The arbitrator will use his or her best efforts to
ensure that the first day of hearing takes place within ten Business Days of the
last response served under Section 12.2. The arbitrator will schedule further
hearings as necessary and appropriate within the arbitrator's discretion.

                  (c)      The arbitrator will use his or her best efforts to
conclude the hearings and render a written opinion and an award within 20
Business Days of commencement of the first arbitration hearing. In no event will
the arbitrator render an award later than ten Business Days from the conclusion
of the hearing, unless otherwise agreed by the parties.

         12.6     DETERMINATION OF ARBITRABLE ISSUES. In the event of a dispute
over whether particular issues are arbitrable under this Agreement, the
arbitrator, and not the court, shall determine whether or not the arbitrator has
jurisdiction over such issues. The arbitrator's decision as to the arbitrator's
jurisdiction over issues is final and binding.

         12.7     SANCTIONS. The arbitrator is empowered to grant sanctions for
dilatory conduct with respect to arbitration under this Agreement.

         12.8     JUDGMENTS. Judgment on the award rendered by the arbitrator
may be entered in any State or Federal court, within California, having

         12.9     FAILURE TO APPEAR. If a party fails or refuses to appear or
participate in the arbitration, or in any portion of the arbitration, after
having been given notice and opportunity to participate as provided in this
Agreement, the arbitration shall proceed. The arbitrator may render a final
award on the basis of the evidence presented by the participating party. An
award rendered under such circumstances is valid and enforceable as if all
parties had participated fully.

the Agreement shall become effective upon the satisfaction or waiver in writing
by each of the parties of all of the following conditions (the "Effective
Date"):


                  (a)      Approval of the Agreement and the transactions
contemplated thereby by the requisite lenders under the Credit Agreement;

                  (b)      Execution by such of the following Plans of
renegotiated contracts as contemplated by the Transition Plan effective January
1, 1999 and incorporating such Plans' agreements to pay retroactive premium

(including Health Net and Foundation Health), Prudential Health Care Plans,
Inc., United HealthCare of California, Inc. and Wellpoint Health Networks
(including Blue Cross of California and California Care);

                  (c)      Assumption by Plans constituting 95% of capitation
amounts payable to MPN for the month of May 1999 of institutional risk effective

characterize the legal implications of such assumption, other than the
assumption of institutional risk; provided, however, that (i) such assumption
shall not affect any Claim a Plan may have against MPN concerning damages
related to such assumption of institutional risk, and (ii) any obligations to
pay institutional capitation to MPN under the Plan Agreements or the Plan
Stipulation subsequent to the applicable date of assumption of institutional
risk shall have been terminated by order of the Bankruptcy Court prior to the

                  (d)      Authorization and approval by the Bankruptcy Court of
MPN's execution and performance of the Agreement. As used in this Section, the
date on which authorization and approval by the Bankruptcy Court occurs shall
mean the date on which the order of the Bankruptcy Court approving this
Agreement as it relates to MPN becomes a Final Order, unless the requirement of
finality is waived by the Special Monitor-Examiner, MPN, MedPartners, and the
Creditors Committee, in which case such date shall be the eleventh day following
the date on which the Bankruptcy Court enters an order approving this Agreement,
unless that order is subject to stay pending appeal, in which case upon such
waiver of the date, shall be no earlier than the first Business Day after the
expiration of the stay;

                  (e)      The Bankruptcy Court order approving this Agreement
shall provide that the parties hereto (and any parties claiming thereto) shall
be prohibited from using any funds deposited in the MPN California Account
otherwise than in accordance with the terms of this Agreement;

precedent to the SPA Effective Date (as defined in) the Supplemental Plan

occur; and

                  (i)      No proceeding is pending for the enjoinment,
suspension, revocation or termination of this Agreement as of the SPA Effective
Date and the Plan Effective Date.

                  (f)      Failure of the Effective Date of the Plan of
Reorganization to occur within 45 days after confirmation of the Plan of

Court, based upon written declarations of MPN Providers, that any of the MPN
Provider thresholds described in Sections 12.2.5 and 12.2.6 of the Supplemental
Plan Agreement will not be met or has not been waived pursuant to the terms of

                  (h)      Conversion of the Bankruptcy Case to a case under

         16.7     COUNTERPARTS; TELEFACSIMILE EXECUTION. This Agreement may be
executed in any number of counterparts and by different parties on separate
counterparts, each of which, when executed and delivered, shall be deemed to be
an original, and all of which, when taken together, shall constitute but one
and the same Agreement. Delivery of an executed counterpart of this Agreement by
telefacsimile shall be equally as effective as delivery of an original executed
counterpart of this Agreement. Any party delivering an executed counterpart of
this Agreement by telefacsimile also shall deliver an original executed
counterpart of this Agreement but the failure to deliver an original executed
counterpart shall not affect the validity, enforceability, and binding effect of
this Agreement.

         16.8     INTEGRATION. This Agreement reflects the entire understanding
of the parties with respect to the transactions contemplated hereby and shall
not be contradicted or qualified by any other agreement, oral or written, before
the date hereof.

         16.9     CONFIDENTIALITY.

                  (a)      Confidential Information. As used in this Agreement,
the term "Confidential Information" means and includes any and all confidential
information regarding MedPartners, its Affiliates other than MPN, or the Managed
Physician Practices that has been or may hereafter be provided or shown to the
State or any of its Representatives (as hereinafter defined) by MedPartners, any
of its Subsidiaries, Affiliates or the Managed Physician Practices or any of
their respective Representatives or is otherwise obtained from a review of
documents from MedPartners or any of its Subsidiaries, Affiliates or the Managed
Physician Practices irrespective of the form of the communication, and also
includes all notes, analysis, compilations, studies, summaries, and other
material prepared by MedPartners or its Representatives containing or based, in
whole or in part, on any information included in the foregoing. For purposes of
this Section 16.9, "Representatives" means directors, officers, employees,
agents, consultants, advisors, conservators, special monitors, examiners or
other representatives, including legal counsel, accountants and financial
advisors of a party.

                  (b)      Nondisclosure. Confidential Information (a) will be
kept confidential by the State and the State shall use reasonable best efforts
to ensure that its Representatives comply with this Section 16.9 and (b) without
limiting the foregoing, will not be disclosed by the State or its
Representatives to any person except with the specific prior written consent of
MedPartners or except as expressly otherwise permitted by the terms of this
Agreement. The State may disclose Confidential Information to only those
Representatives who (i) reasonably require such material in connection with the
obligations under this Agreement, and (ii) are informed by the State of the
confidential nature of the Confidential Information and the obligations of this
Agreement. Neither the State nor its Representatives will use any of the
Confidential Information for any reason or purpose other than in connection with
this Agreement.

                  (c)      Notification. If the State or its Representatives are
requested to disclose any Confidential Information the State will promptly
notify the party furnishing such Confidential Information to permit it to seek a
protective order or take other appropriate action. Each party will reasonably
cooperate in such party's efforts to obtain a protective order or other
reasonable assurance that confidential treatment will be accorded such
Confidential Information. If, in the absence of a protective order, the party or
Representatives are, in the written opinion of its legal


                                       37
<PAGE>   43



counsel, compelled as a matter of law to disclose any such Confidential
Information to a third party, such party may disclose to the third party
compelling disclosure only the part of such Information as is required by law to
be disclosed (in which case, prior to such disclosure, each party will use
reasonable efforts to advise and consult with the party furnishing such
Confidential Information and its counsel as to such disclosure and the nature
and wording of such disclosure) and each party will each use reasonable efforts
to obtain confidential treatment therefor.

                  (d)      Exceptions. None of the foregoing obligations and
restrictions apply to that part of the Confidential Information that the State
demonstrates (i) is or becomes generally available to the public other than as a
result of a disclosure by the State or its Representatives, provided that the
source of such information was not known by the State or its Representatives to
be bound by a confidentiality agreement with MedPartners or MPN, with respect to
such Confidential Information, or (ii) is available, or becomes available, to
the State on a nonconfidential basis, including as a result of MedPartners, its
Affiliates, the Managed Physician Practices or MPN's filing of such information
with the Bankruptcy Court or Los Angeles Superior Court (other than under seal
or subject to similar protections), or submission of such information to the
Office of the United States Trustee.

         Notwithstanding Section 16.9(d)(i) above, the State shall not continue
to disclose Confidential Information learned from a third party if MedPartners
or MPN notifies the State in writing that such information is the subject of a
Confidentiality Agreement between MedPartners or MPN and the party originally
disclosing such information to the State, or its Representatives.

         Nothing herein shall in any way limit any right to obtain such
Confidential Information in any pending or future litigation, administrative, or
other adversarial proceeding (including arbitration or mediation).

         16.10    PRESS RELEASES. Neither MedPartners, MPN nor the State or the
Special Monitor-Examiner shall issue any press release or other public statement
with respect to the execution of this Agreement and the contents hereof without
consulting with the other. MedPartners, MPN and the State will cooperate with
each other prior to issuing any press release or other public statements
regarding this Agreement or the transactions contemplated hereby; provided,
however, MedPartners shall not be required to provide the State with advance
copies or drafts of any documents it files with the Securities and Exchange
Commission or pursuant to applicable stock exchange rules or any press release
or public statement that MedPartners is required, based upon the advice of
counsel, to release under applicable law or stock exchange policy.

         16.11    ACTIONS BY THE STATE. Each of the Commissioner and the DOC
shall act collectively hereunder through the Commissioner. No exercise of
remedies or other actions hereunder shall be effective unless exercised by the
Commissioner. MedPartners and MPN may rely upon the actions of the Commissioner
with respect to any action of the State hereunder.

         16.12    CONSENT TO JURISDICTION. Any suit, including insolvency and
bankruptcy proceedings or other enforcement action relating to MPN or
MedPartners and this Agreement shall be tried and litigated in the state or
federal courts located in the county of Los Angeles, State of California;
provided, however, the Bankruptcy Court also shall have jurisdiction over any
action relating to MPN. Each party waives, to the extent permitted under
applicable law,


                                       38

any right it may have to assert the doctrine of forum non conveniens or to
object to venue to the extent any proceeding is brought in accordance with this
Section.

         16.13    PLAN AND PROVIDER STIPULATIONS. This Agreement shall not in
any manner modify or amend or affect the Provider Stipulation or Plan
Stipulation.

         16.14    THIRD PARTY BENEFICIARIES.

                  (a)      Scope of Rights. This Agreement is for the benefit of
the following entities to the extent provided herein and subject to the
limitations and requirements of this Section:

                           (1)      Holders of MPN Provider Claims to the extent
of seeking to enforce adjudication and payment of their Claims under Section
3.5(b);

                           (2)      Holders of Managed Physician Practice
Provider Claims to the extent of seeking to enforce adjudication and payment of
their Claims under Section 3.5(b);

                           (3)      The Plans to seek an order requiring a party
to specifically perform its obligations under this Agreement including without
limitation the payment of Plan Preserved Claims or Provider Claims held by a
Consenting Plan; and

                           (4)      The Creditors Committee to seek an order
requiring a party to specifically perform its obligations under this Agreement
(each individually, a "Beneficiary," and collectively, the "Beneficiaries").

                  (b)      Jurisdiction and Representative. Any action under
this Section 16.14 against MedPartners for breach of this Agreement may only be
brought on behalf of one or more Beneficiaries by a representative of such
Beneficiary or group of Beneficiaries in the Los Angeles Superior Court, or,
with respect to MPN, the Bankruptcy Court; provided, however, that in the event
any Beneficiary asserts that MedPartners or MPN has violated Section 3.5(b), its
sole remedy shall be arbitration pursuant to Section 12. The representative in
any such action can be any of the following: (i) the Special Monitor-Examiner,
(ii) one or more MPN Provider Claim Beneficiaries as designated by the group,
(iii) one or more Managed Physician Practice Provider Claim Beneficiaries as
designated by the group, (iv) with respect to Beneficiaries holding Managed
Physician Practice Provider Claims, a subcommittee of the Creditors Committee
representing such Beneficiaries, (v) with respect to Beneficiaries holding MTN
Provider Claims, a subcommittee of the Creditors Committee representing such
Beneficiaries, (vi) the Creditors Committee, or (vii) a Plan acting on its own
behalf or otherwise with respect to its rights under Section 16.14(a)(3) (each,
a "Representative").

                  (c)      Threshold for Enforcement. An action to enforce any
right granted to a Beneficiary pursuant to this Section may be commenced only by
a Representative in the following circumstances: (i) physician claimants who are
eligible Beneficiaries holding in aggregate not less than $600,000 of
non-adjudicated Managed Physician Practice Provider Claims; (ii) physician
claimants who are eligible Beneficiaries holding in aggregate not less than
$300,000 of finally adjudicated Managed Physician Practice Provider Claims;
(iii) non-physician claimants who are eligible Beneficiaries holding in
aggregate not less than $5 million in non-adjudicated Provider Claims; (iv)
non-physician claimants who are eligible Beneficiaries holding


                                       39
<PAGE>   45

an aggregate not less than $5 million in, with respect to the Managed Physician
Practices, finally adjudicated and liquidated Managed Physician Practice
Provider Claims and, with respect to MPN, MPN Provider Claims that have become
Allowed MPN Claims; or (v) any Plan with respect to its rights under Section
16.14(a)(3). Notwithstanding the foregoing, with respect to eligible
Beneficiaries who hold pre-petition MPN Provider Claims, no such enforcement
action may be commenced or maintained until the Plan of Reorganization Effective
Date.

                  (d) Notice. Prior to bringing an action, the Representative
shall give notice of intent to sue to MedPartners, MPN, the Creditors Committee
and the Special Monitor-Examiner. Such notice shall provide the name of each
eligible Beneficiary within the group and the amount of each such Beneficiary's
Provider Claim or Plan Preserved Claim or the provision of the Agreement that
such Representative is seeking to enforce. MedPartners and/or MPN, as the case
may be, shall have ten Business Days after receipt of such notice to cause such
Provider Claims or Plan Preserved Claim to be paid or to comply with the
Agreement. If payment or other cure is not made during such cure period, the
Representative may proceed with filing the action or initiating the arbitration,
as the case may be.

                  (e) Limitation on Rights. The benefits conferred to
Beneficiaries pursuant to this Section 16.14 shall be subject to the following
provisions:

                           (i)      Notwithstanding any other provision of this
Agreement to the contrary, any Plan that has made a loan to MedPartners or any
purchaser of the assets of any of MedPartners Managed Physician Practices shall
not have any third party beneficiary rights under this Agreement to pursue any
claim relating to such loan.

                           (ii)     With respect to the rights and benefits
conferred to Providers holding MPN Provider Claims pursuant to this Section
16.14, such rights and benefits may be modified, waived, terminated or released
pursuant to the confirmed and effective Plan of Reorganization, and with respect
to the MPN Provider Claims held by a Consenting Plan, the Supplemental Plan
Agreement, and any other agreement between MPN and a Consenting Plan that (a)
modifies the Supplemental Plan Agreement as to those parties and (b) has been
approved by Final Order of the Bankruptcy Court.

                           (iii)    Neither the expedited procedures provided
for in Section 10.3 hereof nor the provision for stipulated judgment shall apply
to any action brought by or on behalf of one or more Beneficiaries under this
Section 16.14 unless the Beneficiary is acting as the assignee or designee of
the State.

         16.15    EXHIBITS OR SCHEDULES. If and to the extent that any
provisions of any document or agreement incorporated herein shall conflict with
any of the express terms and provisions of this Agreement, the terms and
provisions of this Agreement shall control the rights and obligations of the
parties hereto.

         16.16    ATTORNEYS' FEES. In the event of any dispute between the
parties arising out of this Agreement, the prevailing party shall be entitled to
recover its attorneys' fees and costs.

         16.17    RELATED AGREEMENTS. Additional documents implementing this
Agreement are necessary, including in the case of MPN the Plan of
Reorganization, and in the case of MPN and


                                       40
<PAGE>   46

the Managed Physician Practices an additional agreement (the "Supplemental Plan
Agreement") that shall govern certain rights and obligations of MPN,
MedPartners, those Managed Physician Practices that elect to receive the
benefits of this Agreement by executing the Supplemental Plan Agreement (each
such Managed Physician Practice, a "Consenting MPP"), the direct and indirect
subsidiaries of MedPartners which provide management of the non-medical
operations of the Managed Physician Practices, and those Plans that elect to
receive the benefits of this Agreement by executing the Supplemental Plan
Agreement (each such Plan, a "Consenting Plan"; together with MPN, MedPartners,
the Consenting MPPs and such subsidiaries, the "Supplemental Plan Agreement
Parties"). MedPartners and such subsidiaries, as appropriate, will use their
best efforts to cause the Managed Physician Practices to become Consenting MPPs.
The Supplemental Plan Agreement shall be limited to the California Operations
and shall include as covenants each of the provisions set forth below in this
Section 16.17 regarding certain aspects of the Plan of Reorganization, certain
waivers, releases and subordinations affecting Claims of the Supplemental Plan
Agreement Parties, and certain other matters, all of which are deemed to be
material to the performance by MPN and MedPartners of their obligations under
this Agreement, and each of which shall be deemed material to the agreement by
any Supplemental Plan Agreement Party to grant such waivers, releases or
subordinations.

                  (a) Each Consenting Plan shall support confirmation and
implementation of the Plan of Reorganization; provided, however, that:

                           (i)      The obligations of a Consenting Plan which
is a member of the Creditors Committee regarding this Section 16.17(a) shall be
subject to such Plan's fiduciary duties as such a member, exercised reasonably
and in good faith;

                           (ii)     No Consenting Plan shall be required to
support a plan of reorganization that contains terms which are materially
adverse to the Consenting Plans other than as set forth in this Agreement, the
Supplemental Plan Agreement, or as otherwise agreed to by a Consenting Plan;

                  (iii)    The Consenting Plans' obligations to support the Plan
of Reorganization are contingent upon confirmation of such Plan of
Reorganization by August 31, 2000 (provided further, however, that a failure to
confirm the Plan of Reorganization by such date shall not excuse compliance with
this provision if the delay is attributable to the Consenting Plans).

                           (iv)     The Consenting Plans, the Creditors
Committee, the Special Monitor-Examiner, MPN and MedPartners shall meet and
confer in an effort to agree upon and propose an appropriate minimum number of
Providers and Plans who must become Consenting Providers and Consenting Plans
for the waiver, release, subordination and other provisions of the Supplemental
Plan Agreement to be enforceable, such thresholds to be set at levels that
assure that Consenting Providers and Consenting Plans, as well as the parties to
this Agreement, receive, to the greatest extent practicable, the reasonable
benefit of their bargain.

                  (b) Except with respect to a Consenting Provider concerning
its Provider Claim, each Consenting Provider, each Consenting Plan, each
Consenting MPP, MedPartners and MPN shall agree (i) not to pursue any Claims
which, pursuant to the terms of this Agreement, the Plan


                                       41
<PAGE>   47

of Reorganization or the Supplemental Plan Agreement are waived, released or
subordinated, until (x) the effectiveness of such waiver, release or
subordination, or (y) a Default under this Agreement, the Plan of Reorganization
or the Supplemental Plan Agreement, as applicable; and (ii) to toll all
applicable statutes of limitations as to any Claims which, pursuant to this
Agreement, the Plan of Reorganization, or the Supplemental Plan Agreement, are
subject to waiver, release or subordination in accordance with the terms thereof
until ninety days after the termination of the standstill referred to in (i)
above. Notwithstanding anything to the contrary, nothing herein shall stay or
restrain the holder of a Claim against a Managed Physician Practice from
pursuing such Claim against the Managed Physician Practice.

                  (c) The Plan of Reorganization, in the case of MPN, and the
Supplemental Plan Agreement, in the case of MPN and the Managed Physician
Practices, shall provide that to receive the benefits of this Agreement, each
holder of a Provider Claim other than a Plan shall be required to sign a MPN
Provider Release or a MPPP Release, or both Releases, as applicable. In the case
of a Plan, the Plan shall sign a release with respect to a Provider Claim held
by a Plan in such form as is agreed upon in the Supplemental Plan Agreement.

                  (d) In connection with the Plan of Reorganization, each
Consenting Plan shall subordinate its MPN Plan Subordinated Claims to, and only
to, the MPN Provider Claims held by Consenting MPN Providers and the Plan
Preserved Claims against MPN held by Consenting Plans. Any distribution on
account of the MPN Plan Subordinated Claims shall be assigned for the benefit of
Consenting Providers on account of their MPN Provider Claims which become
Allowed MPN Claims in such amount as is necessary to fulfill the MedPartners
Funding Commitment on account of such Allowed MPN Claims and, as to any excess,
to the MedPartners California Account. The MPN Plan Subordinated Claims include,
by way of example and not limitation: (u) all Claims asserted by a
Consenting Plan against MPN for prospective damages (including lost profits and
costs incurred in recontracting with other Providers) arising as a consequence
of (i) the failure to perform for the full remaining term under a Health Care
Services Agreement between MPN and such Plan as a consequence of the sale of
practice assets of a Managed Physician Practice or closure of a Managed
Physician Practice or clinic thereof (including pre-Petition Date and
post-Petition Date sales or closures), (ii) the failure by MPN to assume in the
Bankruptcy Case any lease or executory contract relating to the post-Petition
Date sale or closure of a Managed Physician Practice or clinic thereof, (iii)
increased capitation or fee for service expenses incurred by a Consenting Plan
as a result of a pre-Petition Date or post-Petition Date clinic closure through
the remaining term of the Health Care Services Agreement, or (iv) the transfer
of institutional risk to such Consenting Plan, (v) all Claims relating to a
Health Care Services Agreement arising from the failure by MedPartners to sell
the practice assets of Mullikin Practice Group or Southern California Medical
Corporation or resulting from a closure thereof; (w) all Claims resulting from
MPN's rejection and the Managed Physician Practice's termination of a Consenting
Plan's Health Care Services Agreements; (x) all Claims for damages under a
Health Care Services Agreement (including consequential, damage to reputation,
special, incidental or indirect damages, loss of profits or income, exemplary or
punitive) by a Consenting Plan against MPN or the Managed Physician Practices
that did not result in actual pecuniary losses to such Consenting Plan; (y)
Claims incurred as a result of a Consenting Plan moving members from a Managed
Physician Practice or MPN; and (z) all Claims arising from the tortious acts or
omissions of MPN or the Managed Physician Practices. Notwithstanding the
foregoing, such subordinated Claims shall not include Claims which are


                                       42
<PAGE>   48

Plan Preserved Claims arising from Health Care Services arranged for by MPN and
rendered prior to the sale, closure or transfer, and the out-of-pocket expenses
relating to processing of such Claims.

                  (e) Effective upon the satisfaction of the MedPartners Funding
Commitment, each Consenting Plan shall waive and release all Claims against
MedPartners, any affiliate of MedPartners (other than MPN) and the Consenting
MPPs related to the California Operations: (w) which are alleged to exist solely
on the basis that MedPartners or an affiliate of MedPartners (other than MPN) is
liable on account of alter ego, piercing the corporate veil, respondeat
superior, principal-agent, substantive consolidation or similar theories of
vicarious, nonconsensual liability by, through or on account of MPN's or a
Managed Physician Practice's liability to the Consenting Plan; (x) Claims for
damages (including consequential, damage to reputation, special, incidental or
indirect damages, loss of profits or income, exemplary or punitive) that did not
result in actual pecuniary losses to such Consenting Plan; and (y) sounding in
tort. Notwithstanding the foregoing, such waiver and release shall not apply to
any Claims arising under a direct contract, excluding a Health Care Services
Agreement, but including, without limitation (i) any lease, surety arrangement
or guaranty, and (ii) any guaranty of a Health Care Services Agreement to which
MedPartners or an affiliate of MedPartners (other than MPN) or a Managed
Physician Practice is a party.

                  (f) In connection with the Plan of Reorganization, and
otherwise with respect to the Managed Physician Practices, MPN and the
Consenting MPPs shall each waive and release all Claims against Consenting Plans
except for MPN Preserved Claims and Managed Physician Practice Preserved Claims;
provided, however, that any Claims waived and released pursuant to this section
shall be waived and released for purposes of (i) seeking affirmative relief, or
(ii) defense of or setoff against MPN Plan Preserved Claims and Managed
Physician Practice Plan Preserved Claims, as applicable, and shall only be
preserved for purposes of defense of or setoff against the MPN Plan Subordinated
Claims and the Managed Physician Practice Plan Subordinated Claims, as
applicable. Claims waived by MPN or a Managed Physician Practice include, by way
of example and not limitation: (w) Claims related to the recovery of capitation
fees or other amounts that would be due after the dates of the sale of the
practice assets of a Managed Physician Practice or the rejection of an agreement
by MPN; (x) Claims related to the sale or closure of a Managed Physician
Practice or in connection with the movement of members from a Managed Physician
Practice; (y) Claims for damages (including consequential, damage to reputation,
special, incidental or indirect damages, loss of profits or income, exemplary or
punitive) against a Consenting Plan that did not result in actual pecuniary
losses to MPN or an MPP; and (z) Claims arising from the tortious acts or
omissions of the Consenting Plans.

                  (g) At such time as a Consenting Plan waives and releases all
Claims identified in Section 16.17(e), MedPartners and its affiliates (other
than MPN) and the Consenting MPPs shall waive and release all Claims against
each Consenting Plan related to the California Operations: (y) Claims for
damages (including consequential, damage to reputation, special, incidental or
indirect damages, loss of profits or income, exemplary or punitive) that did not
result in actual pecuniary losses to MedPartners or its affiliates (other than
MPN); and (z) sounding in tort. Notwithstanding the foregoing, such waiver and
release shall not apply to any Claims arising under a direct contract, excluding
a Health Care Services Agreement, but including, without


                                       43
<PAGE>   49

limitation (i) any lease, surety arrangement or guaranty, and (ii) any guaranty
of a Health Care Services Agreement to which a Consenting Plan is a party.

                  (h) MPN shall agree that with respect to the Claims against a
Consenting Plan for allegedly improper, excessive or wrongful capitation
deductions taken by such Plan that allegedly arose out of an improper, excessive
or wrongful payment to a Provider, it shall first object to the Claim of any
Provider holding a Provider Claim and assert the offset in defense to that
portion of an MPN Provider Claim that becomes an Allowed MPN Claim to the
fullest extent available as an offset, and prosecute the objection to a final
resolution or compromise. In the event of a compromise with an MPN Provider,
however, the balance of the setoff not recovered or set off against the Provider
may not be recovered from a Consenting Plan. MedPartners or a Consenting MPP
shall agree that with respect to the Claims against a Consenting Plan for
allegedly improper, excessive or wrongful capitation deductions taken by such
Plan that allegedly arose out of an improper, excessive or wrongful payment to a
Provider, it shall contest the claim of any Provider holding a Provider Claim to
the fullest extent available as an offset through the conclusion of the final
adjudication or compromise thereof. In the event of a compromise with a Managed
Physician Practice Provider, however, the balance of the set off not revived or
set off against such Provider may not be recovered from a Consenting Plan. Any
amount so collected from Providers by offset or otherwise shall be deposited in
the MPN California Account or the MedPartners California Account, as the case
may be. To the extent such Consenting Provider has repaid such overpayments to a
Consenting Plan or such offset is not otherwise obtained from the Consenting
Provider, then MPN and the affected Managed Physician Practice may pursue such
Claims against the Consenting Plan and, in that case, MPN or the affected
Managed Physician Practice, as the case may be, and the Consenting Plan shall
cooperate in good faith to promptly settle and satisfy such Claim; and, if it
cannot be settled, the parties to the dispute agree to resolve such dispute by
arbitration pursuant to a process to be set forth in the Plan of Reorganization
and the Supplemental Plan Agreement. As a part of such settlement or
arbitration, MPN or the affected Managed Physician Practice, as the case may be,
shall assign to the Consenting Plan any Claims against the Consenting Provider
on whose account the capitation payment was made.

                  (i) No waiver or subordination of any Claim by any Consenting
Plan, Consenting Provider, MPN, Consenting MPP, MedPartners or any affiliate,
nor such entity's participation in this Agreement, will impair the ability to
recover on account of any Claim by any of the foregoing entities against any
other of the foregoing entities that is not waived, released or subordinated
pursuant to the terms of this Agreement or the Supplemental Plan Agreement.

                  (j) Each Consenting Provider shall have offered each
Consenting Plan the opportunity to assume institutional risk pursuant to this
Agreement through the earlier of (i) December 31, 1999 or (ii) the expiration of
the applicable Consenting Provider's contract with MPN, pursuant to economic
terms no less favorable than MPN received from such applicable Consenting
Provider immediately prior to the transfer of such institutional risk to the
Consenting Plan.

                  (k) Each entity that purchases or acquires, directly or
indirectly, an interest in the practice assets of a Managed Physician Practice
shall have offered (or shall have used its best efforts to see that a Managed
Physician Practice shall offer) to each Consenting Plan the


                                       44
<PAGE>   50

opportunity to obtain covered services under a Health Care Services Agreement
through the earlier of (i) December 31, 1999 or (ii) the expiration of the
applicable Provider Contract with MPN, pursuant to economic terms that are no
less favorable than MPN received from such Managed Physician Practice
immediately prior to the sale of its practice assets by MedPartners.

                  (l) Prior to the consummation of a sale or transfer of the
practice assets of a Managed Physician Practice, or the issuance of a notice of
intent to close (pursuant to Section 3.5(e)) a Managed Physician Practice, each
Consenting Plan shall satisfy those terms set forth in Section 13 of the Plan
Stipulation concerning moving of Plan enrollees, subject to the satisfaction of
those terms and conditions set forth in Sections 8, 9, 18 and 20 of the Plan
Stipulation in the form approved by the Court as of May 2, 1999, without
reference to any subsequent amendments or modifications thereto.

                  (m) MedPartners, the Consenting MPPs and their affiliates
shall subordinate to, and only to, the MPN Provider Claims held by Consenting
Providers, all of their Claims against the bankruptcy estate of MPN including,
without limitation, any Claims MedPartners may have to receive any amounts due
under the Management Agreement on or prior to the Petition Date by reason of the
rejection in the Bankruptcy Case of the Management Agreement or otherwise.

                  (n) The Plan of Reorganization for MPN shall provide that upon
the full and final satisfaction of the MedPartners Funding Commitment, MPN
releases MedPartners and its affiliates from any and all claims, liabilities,
actions and causes of action arising prior to the satisfaction of the
MedPartners Funding Commitment.

                  (o) Each Supplemental Plan Agreement Party reserves all rights
with respect to counterclaims, cross-complaints, setoffs, recoupments and other
defenses not otherwise waived, released or subordinated as to and up to the
amount of any Claim of such Supplemental Plan Agreement Party not waived by
reason of this Section 16.17. In addition, notwithstanding anything herein to
the contrary, each Supplemental Plan Agreement Party shall reserve as a defense
to recovery of any Claim not waived pursuant to the terms hereof, that the acts
of the Plans, or the acts of MedPartners, MPN, the Managed Physician Practices
or the affiliates thereof, as the case may be, were reasonable responses to
breaches of the applicable agreements by the other party or parties, and the
other party or parties to the agreement may dispute the validity of the defense,
but not the right to assert the defense.

                  (p) The Plan of Reorganization and the Supplemental Plan
Agreement shall contain other appropriate terms and conditions, including
appropriate remedies of the parties thereto, such as specific performance. Any
breach of or default under the Supplemental Plan Agreement shall not be a cross
default of this Agreement.

         Upon the occurrence of the Supplemental Plan Agreement Effective Date
(as defined in the Supplement Plan Agreement), the provisions of Section 16.17
of the Agreement shall be amended and superseded by the Supplemental Plan
Agreement; provided, however, that if the Supplemental Plan Agreement terminates
pursuant to Section 12.4.1 of the Supplemental Plan Agreement (other than
Section 12.4.1(c) thereof) then Section 16.17 shall be reinstated.

         16.18    REPRESENTATION BY COUNSEL; DRAFTS; INTERPRETATION. The parties
each acknowledge that each party to this Agreement has been represented by
counsel in connection with this Agreement and the transactions contemplated by
this Agreement. Accordingly, any rule of law, including, but not limited to,
Section 1654 of the California Civil Code, or any legal decision that would
require interpretation of any claimed ambiguities in this Agreement against the
party that drafted it has no application and is expressly waived. In addition,
the parties acknowledge that there have been a number of drafts of this
Agreement. The presence, absence, inclusion or deletion of any provision in any
prior draft shall not be evidence of the intent of the parties. The provisions
of this Agreement shall be interpreted in a reasonable manner to effect the
intent of the parties.

         16.19    WAIVER OF DEFENSES. MedPartners hereby waives and agrees not
to assert or take advantage of: (a) any defense to its obligations hereunder by
reason of the modification of the time, manner or terms of payment of any
Provider Claim, pursuant to or by reason of the terms of this Agreement or with
the consent of MPN or the Managed Physician Practices or (b) any other
forbearance by any Provider as applicable, provided each Provider Claim is
otherwise eligible for payment under the MedPartners Funding Commitment and
Section 3.5.

         16.20    FURTHER ASSURANCES. Each of the parties and the Beneficiaries
agree to cooperate with each, take such acts, and negotiate and execute any
additional agreements, including, without limitation any amendments to this
Agreement, which are reasonably necessary to carry out and effectuate the
transactions and agreements contemplated in this Agreement.

17. RELEASE.

         17.1     RELEASE. Upon the full and final satisfaction of the
obligations set forth in this Agreement by MPN and MedPartners, MPN and
MedPartners and their assigns (and all past, present and future successors,
beneficiaries, representatives, its businesses, companies, corporations,
partners, business associates, affiliated businesses, parent businesses,
associated businesses, co-owned businesses, stockholders, directors, employees,
agents, heirs, legatees, executors, administrators, legal counsel and insurers)
on the one hand and the State or its representatives (including, but not limited
to, all past, present and future administrators, officials, directors, officers,
employees, agents, consultants, advisors, conservators, special monitors,
examiners, legal counsel, accountants, financial advisors, whether retained
directly or indirectly on behalf of the State or its representatives) and their
assigns, heirs, legatees, or executors, on the other hand, do hereby fully and
forever release and discharge the other for and from all manner of action or
causes of action in law or in equity, suits, liabilities, liens, contracts,
agreements, promises, demands, affirmative relief or offset, debts, claims,
damages, expenses, costs, causes or demands of every nature, kind and
descriptions whatsoever, or anything whatsoever, known or unknown, fixed or
contingent, which they now have or may now have against each other, or which
they may hereafter have by reason of any matter whatsoever arising prior to the
Agreement Date or arising out of or related to the State Actions.
Notwithstanding the above, this Section shall not act as a release between MPN
and MedPartners and their assigns on the one hand, and any Beneficiary or its
representatives and assigns, on the other hand.

         17.2     WAIVER. The parties hereto acknowledge that they have been
advised by legal counsel and are familiar with the provisions of California
Civil Code ss. 1542, which provides:


                                       46
<PAGE>   52

                  A general release does not extend to claims which the creditor
                  does not know or expect to exist in his favor at the time of
                  the executing of the release, which if known by him, must have
                  materially affected his settlement with the debtor.

                  Each party hereto hereby expressly waives all rights each of
them may have under Civil Code ss. 1542, as well as under any other statute or
common law principles of similar effect relating to the claims released.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed in Los Angeles, California.
