                                  INTRODUCTION


         MedPartners Provider Network, Inc., a California corporation ("MPN,"
the "Company" or the "Debtor"), proposes this "Second Amended Chapter 11 Plan
of MedPartners Provider Network, Inc. dated July 7, 2000" (the "Plan") for the
resolution and satisfaction of all Claims against and Interests in the Debtor.
This is a liquidating plan pursuant to which all of MPN's Assets are to be
distributed to creditors in accordance with priorities established by the
Bankruptcy Code. This Plan also implements the Settlement Agreement and the
Supplemental Plan Agreement (each as defined herein), which, in general terms,
combine to provide for, among other things: (a) supplemental funds to be made
available by Caremark Rx, Inc., f/k/a MedPartners, Inc.,  for additional
payments to the consenting holders of eligible Allowed Claims that elect to
participate in the benefits of the Settlement Agreement; and (b) the consensual
subordination by various parties of certain claims in favor of, and to enhance
distributions to, such participating holders of such eligible Allowed Claims.
Accordingly, holders of general unsecured prepetition claims against the Estate
that are or become Allowed Claims will be entitled to receive their respective
Pro Rata share of all funds of the Estate to be distributed under the Plan on
account of such Allowed Claims. To the extent such holders are eligible and
elect to participate in the Settlement Agreement by agreeing to abide by the
terms and conditions of this Plan, those holders will also be entitled to
receive supplemental distributions on account of their claims that are eligible
for the benefits of the MedPartners Funding Commitment (as defined herein).
ELIGIBLE CREDITORS THAT DO NOT ELECT TO PARTICIPATE IN THE SETTLEMENT AGREEMENT
WILL RECEIVE NO SUCH SUPPLEMENTAL DISTRIBUTIONS AND WILL NEITHER PARTICIPATE IN
THE BENEFITS OF THE MEDPARTNERS FUNDING COMMITMENT NOR SHARE IN THE BENEFITS OF
THE CONSENSUAL SUBORDINATIONS GRANTED BY OTHER INTERESTED PARTIES IN ANY MANNER
WHATSOEVER.(1)


         The Disclosure Statement for this Plan contains a discussion of the
Debtor's history, business, results of operations, resolution of material
disputes, significant asset sales, financial projections for the liquidation
and distribution of the Debtor's remaining assets and the


--------------------
(1) Copies of the Settlement Agreement and the Supplemental Plan Agreement are
    annexed hereto as Exhibits "1" and "2," respectively.


                                      -1-

funds to be made available under the MedPartners Funding Commitment, and a
summary of this Plan. The Debtor urges all holders of Claims and Interests
entitled to vote on the Plan to read the Plan and the Disclosure Statement in
their entirety before voting to accept or reject the Plan. To the extent the
Disclosure Statement is inconsistent with the Plan, the Plan will govern. No
solicitation materials other than the Disclosure Statement and any schedules
and exhibits attached thereto or referenced therein, or otherwise enclosed with
the Disclosure Statement served by the Debtor on interested parties, have been
authorized by the Debtor or the Bankruptcy Court for use in soliciting
acceptances or rejections of the Plan.

Claims against the Debtor, including the following categories of Claims (with a
parenthetical denoting each such category's sub-classification within Class 3):
MPN Provider Claims (Class 3A); MPN Plan Preserved Claims (Class 3B);
Consenting Provider Subordinated Claims (Class 3C); MPN Plan Subordinated Claims
(Class 3D); Consenting MPP Subordinated Claims (Class 3E); MedPartners
Subordinated Claims (Class 3F); and Other Unsecured Claims (Class 3G). The
sub-classifications identified herein are for descriptive purposes and for
purposes of effectuating certain voluntary subordinations to be implemented in
connection with this Plan. The sub-classifications do not give rise to any
separate or different voting rights or claims treatment; all Allowed Class 3
Claims, without regard for sub-classifications, shall be considered to be one
Class for voting purposes and each such Claim shall receive the treatment
provided for in this Section 2.3.

         Class 3 is Impaired under the Plan. As set forth below, distributions
to holders of Allowed Class 3 Claims shall be made from:

                  (a)      as to each holder of an Allowed Class 3 Claim, from
the Estate; and

                  (b)      as to Consenting Providers, Consenting Plans to the
extent of any Final Preserved Claims against MPN, MedPartners, Consenting MPI
Subs and Consenting MPPs, from the Estate, from funds that, in the absence of
the subordination of the Class 3 Subordinated Claims, would be distributed by
the Estate to the holders of the Class 3 Subordinated Claims and from funds made
available under the MedPartners Funding Commitment.

                           2.3.1    PRO RATA DISTRIBUTIONS FROM THE ESTATE.
Subject to the voluntary subordination of Claims described in to Section 2.3.2
below, each holder of an Allowed Class 3 Claim shall receive, in full and
complete satisfaction of all Claims against the Debtor, Cash in an amount equal
to such holder's Pro Rata share of all of the Assets of the Estate (including
funds deposited in the MPN California Account, but excluding any funding
provided


                                      -21-
<PAGE>   29

by MedPartners pursuant to the MedPartners Funding Commitment) remaining after
subtracting all amounts necessary to fund or pay (a) the Operating Reserve and
all Disputed Claims Reserves, and (b) Allowed Administrative Claims, Allowed
Secured Claims and Allowed Priority Claims. The manner and timing of
distributions to holders of Allowed Class 3 Claims is set forth in Section 6.12
below.

                           2.3.2    SUBORDINATED ALLOWED UNSECURED CLAIMS. On
the Effective Date, in accordance with Section 5.7 below and pursuant to the
terms and conditions specified in the MPN Provider Release, the MPN Plan
Release, the MedPartners Release and the Supplemental Plan Agreement, each as
applicable, all Class 3 Subordinated Claims shall be subordinated, to the extent
provided in this Plan, to the Allowed MPN Provider Claims of Consenting
Providers, Consent Plans, Consenting MPP's, and MedPartners and its affiliates
and MPN Plan Preserved Claims to the extent they are or become Allowed MPN
Claims. In addition, any MPN Provider Claims held by MedPartners, its affiliates
or any Consenting MPP's will be subordinated to, and only to, all Allowed Class
3 Claims held by Consenting Providers or Consenting Plans that are entitled to
satisfaction under the MedPartners Funding Commitment until the MedPartners
Funding Commitment has been fully satisfied with respect to all Class 3 Claims
that become Allowed Class 3 Claims. All funds that would be distributed to
holders of the Class 3 Subordinated Claims in the absence of such subordination
instead will be redirected and distributed in exactly the same manner as any and
all funds provided by MedPartners under the MedPartners Funding Commitment
pursuant to Section 6.12 below.

                           2.3.3    DISTRIBUTIONS FROM THE MEDPARTNERS FUNDING
COMMITMENT. Pursuant to the Settlement Agreement, the $40 Million LC is
available to satisfy obligations subject to the MedPartners Funding Commitment,
and MedPartners has agreed to be responsible for the satisfaction of the
obligations specified in the Settlement Agreement on the terms and conditions
set forth therein. Each Consenting Provider, Consenting Plan, Consenting MPP,
and each of MedPartners and its affiliates, to the extent of its respective
Allowed MPN Provider Claims in Class 3A and Allowed MPN Plan Preserved Claims in
Class 3B, as applicable, after the exercise of all rights of setoff or
recoupment of MPN with respect thereto in accordance with


                                      -22-
<PAGE>   30

applicable law and the Supplemental Plan Agreement, shall be entitled to share
in the distribution of: (a) funds made available under the MedPartners Funding
Commitment, whether pursuant to draws made on the $40 Million LC or otherwise;
and (b) funds made available to such parties as a result of the subordination of
the Class 3 Subordinated Claims described in Section 2.3.2 above; provided,
however, that: (x) any MPN Provider Claims held by MedPartners, its affiliates
or any Consenting MPP's will be subordinated to, and only to, all Allowed Class
3 Claims held by Consenting Providers or Consenting Plans that are entitled to
satisfaction under the MedPartners Funding Commitment until the MedPartners
Funding Commitment has been fully satisfied with respect to all such Allowed
Class 3 Claims; and (y) any distribution to be made to Consenting Plans shall
be subject to the provisions of Section 20.18 of the Supplemental Plan Agreement
or any other agreement between MPN and a Consenting Plan that modifies the
Supplemental Plan Agreement as to those parties and has been approved by Final
Order of the Bankruptcy Court. The manner and timing of such distributions is
set forth in Section 6.12 below.

                  In addition, in connection with the solicitation of votes on
the Plan, Consenting Providers holding MPN Provider Claims that are or become
Allowed Class 3A Claims shall be entitled to make the 90% Cash Election provided
for under the Plan.

                           2.4      CLASS 4: INTERESTS OF HOLDERS OF MPN COMMON
STOCK. Class 4 consists of all Interests in MPN arising from the common stock,
and all rights to acquire any such common stock, issued by MPN and outstanding
immediately prior to the Effective Date, and all other rights and Interests
thereunder. Class 4 is not Impaired under the Plan. MedPartners, the sole holder
of Allowed Class 4 Interests, shall retain its common stock interests in MPN,
and the legal, equitable and contractual rights to which such Interests entitle
MedPartners shall be unaltered by the Plan.

                        TREATMENT OF UNCLASSIFIED CLAIMS

                  3.1      UNCLASSIFIED CLAIMS.

                           3.1.1    ADMINISTRATIVE CLAIMS. Subject to the
allowance procedures and deadlines provided herein and in the Provider
Stipulation, the Revested Debtor shall pay to each holder of an Allowed
Administrative Claim, on account of the Allowed Administrative Claim and in full
satisfaction thereof, Cash equal to the amount of such Allowed Administrative
Claim, unless the holder agrees to other treatment. Except as otherwise
provided herein or a prior order of the Bankruptcy Court: (i) payment of an
Administrative Claim that is an Allowed Claim as of the Effective Date shall be
made on the later of the Effective Date or the date such payment would have
become due for payment of such Allowed Claim in the absence of the Chapter 11
Case, whether pursuant to contract or applicable nonbankruptcy law; and (ii)
payment of an Administrative Claim that becomes an Allowed Claim following the
Effective Date shall be made on or before the date that is thirty (30) days
after an order deeming such Administrative Claim an Allowed Claim becomes a
Final Order. Treatment of Allowed Administrative Claims in accordance with this
Section 3.1.1 shall be in full and final satisfaction of any and all such
Claims, including any and all Allowed Administrative Claims arising under or
pursuant to the Plan Stipulation or the Provider Stipulation.

                           3.1.2    PAYMENT OF STATUTORY FEES. On or before the
Effective Date, all fees due and payable pursuant to 28 U.S.C. ss. 1930, as
determined by the Bankruptcy Court at the Confirmation Hearing, shall be paid in
full, in Cash.

                           3.1.3    PAYMENT OF PRIORITY TAX CLAIMS. In
accordance with Bankruptcy Code section 1129(a)(9)(C), except as otherwise
agreed to by the parties, each holder of an Allowed Priority Tax Claim shall
receive from the Revested Debtor deferred Cash payments over a period not
exceeding six (6) years from the date of assessment of such Claim. Payments
shall be made in equal, semi-annual installments and each installment shall
include simple interest accrued on the unpaid portion of such Claim at the rate
required by 26 U.S.C. section 2661; provided, however, that MPN reserves the
right to pay any Allowed Priority Tax Claim, or


                                      -24-
<PAGE>   32

any remaining balance of such Claim, in part or in full, in Cash, at any time on
or after the Effective Date, without premium or penalty.

                           3.1.4  DEADLINE FOR FILING ADMINISTRATIVE CLAIMS.
                                    (a)  Administrative Claims Other Than
Tax Claims.  Other than with respect to (i) Administrative Claims for which the
Bankruptcy Court previously has established Claims Bar Dates, and (ii) Tax
Claims addressed in section 3.14(b) below, requests for payment or proofs of
Administrative Claims, including Claims of all professional or other entities
requesting compensation or reimbursement of expenses pursuant to Bankruptcy Code
sections 327, 328, 330, 331, 503(b) or 1103 for services rendered on or
before the Effective Date (including any compensation requested by any
professional or any other entity for making a substantial contribution in the
Chapter 11 Case), must be Filed and served on MPN and its counsel no later than
the Administrative Claims Bar Date. Objections to any such Administrative Claims
must be Filed and served on the claimant no later than thirty (30) days after
the Administrative Claims Bar Date. MPN shall use reasonable efforts to promptly
and diligently pursue resolution of any and all disputed Administrative Claims.

                   Holders of Administrative Claims, including all professional
 or other entities requesting compensation or reimbursement of expenses
 pursuant to Bankruptcy Code sections 327, 328, 330, 331, 503(b) or 1103 for
 services rendered on or before the Effective Date (including any compensation
 requested by any professional or any other entity for making a substantial
 contribution in the Chapter 11 Case), that are required to File a request for
 payment of such Claims and that do not File such requests on or before the
 Administrative Claims Bar Date shall be barred from asserting such Claims
 against the Debtor, the Estate, the Revested Debtor, any other Person or
 Entity, or any of their respective property.

                           (b)  Tax Claims.  All requests for payment of
Claims by a governmental unit for Taxes (and for interest and/or penalties
related to such Taxes) for any tax year or period, all or any portion of which
occurs or falls within the period from and including the Petition Date through
and including the Effective Date, and for which no bar date has
otherwise been previously established, must be Filed on or before the later of:
(a) sixty (60) days


                                      -25-

following the Effective Date; or (b) ninety (90) days following the filing of
the tax return for such Taxes for such tax year or period with the applicable
governmental unit. Any holder of a Claim for Taxes that is required to File a
request for payment of such Taxes and other monies due related to such Taxes and
which does not File such a Claim by the applicable bar date shall be forever
barred from asserting any such Claim against any of the Debtor, the Estate, the
Revested Debtor or their respective Assets, whether any such Claim is deemed to
arise prior to, on, or subsequent to the Effective Date, and shall receive no
distribution under the Plan or otherwise on account of such Claim.

                                    ARTICLE 4

              TREATMENT OF EXECUTORY CONTRACTS AND UNEXPIRED LEASES

         4.1  ASSUMPTION; ASSIGNMENT.  As of the Effective Date, the Debtor
in Possession shall assume or assume and assign, as applicable, pursuant to
Bankruptcy Code section 365, each of the executory contracts and unexpired
leases of the Debtor that are identified in Exhibit "8" to the Disclosure
Statement that have not expired under their own terms prior to the Effective
Date. Solely with respect to any executory contracts or unexpired leases related
to MPN's property interests in any tangible assets, the Debtor reserves the
right to amend such Exhibit not later than ten (10) days prior to the
Confirmation Hearing either to: (a) delete any executory contract or lease
listed therein and provide for its rejection pursuant to Section 4.4 hereof, or
(b) add any executory contract or lease to such Exhibit, thus providing for its
assumption or assumption and assignment, as applicable, pursuant to this Section
4.1. The Debtor shall provide notice of any such amendment of such Exhibit to
the parties to the executory contract or lease affected thereby and counsel for
the Committee not later than ten (10) days prior to the Confirmation Hearing.
The Confirmation Order shall constitute an order of the Bankruptcy Court
pursuant to Bankruptcy Code section 365 approving all such assumptions or
assumptions and assignments, as applicable, described in this Section 4.1, as of
the Effective Date.

         4.2  CURE PAYMENTS; ASSURANCE OF PERFORMANCE.  Any monetary defaults
under each executory contract and unexpired lease to be assumed under the Plan
shall be satisfied,


                                      -26-
<PAGE>   34
pursuant to Bankruptcy Code section 365(b)(1), in either of the following, ways:
(a) by payment of the default amount in Cash, in full on the Effective Date; or
(b) by payment of the default amount on such other terms as may be agreed to by
the Debtor and the non-Debtor parties to such executory contract or lease. In
the event of a dispute regarding (i) the amount or timing of any cure payments,
(ii) the ability of the Revested Debtor or an assignee of the Debtor to provide
adequate assurance of future performance under the contract or lease to be
assumed or assumed and assigned, as applicable, or (iii) any other matter
pertaining to assumption or assumption and assignment of the contract or lease
to be assumed, the Revested Debtor shall pay all required cure amounts promptly
following the entry of a Final Order resolving the dispute.

         4.3  OBJECTIONS TO ASSUMPTION OF EXECUTORY CONTRACTS AND UNEXPIRED
LEASES.  To the extent that any party to an executory contract or unexpired
lease identified for assumption asserts arrearages or damages pursuant to
Bankruptcy Code section 365(b)(1), or has any objection with respect to adequate
assurance of future performance, any proposed assumption, revestment, cure or
assignment on the terms and conditions provided herein, all such arrearages,
damages and objections must be Filed and served: (a) as to any contracts or
leases identified on the form of Exhibit "8" included with the Disclosure
Statement that is mailed to any party to any such contract or lease along with
all other solicitation materials accompanying the Plan, within the same deadline
and in the same manner established for the Filing and service of objections to
Confirmation; and (b) as to any contracts or leases identified in any subsequent
amendments to Exhibit "8" to the Disclosure Statement that is mailed to any
party to any such contract or lease not later than ten (10) days prior to the
Confirmation Hearing, in such a manner as to be received by the Bankruptcy Court
and counsel for MPN no later than one (1) day prior to the Confirmation Hearing.

         Failure to assert such arrearages, damages or objections in
the manner described above shall constitute consent to the proposed assumption,
revestment, cure or assignment on the terms and conditions provided herein,
including an acknowledgement that the proposed assumption and/or assignment
provides adequate assurance of future performance and that that amount
identified for "cure" on Exhibit "8" to the Disclosure Statement is the amount
necessary


                                      -27-
<PAGE>   35
to cover any and all outstanding defaults under the executory contract or
unexpired lease to be assumed, as well as an acknowledgement and agreement that
no other defaults exist under such contract or lease.

                   If any assumption of an executory contract or unexpired lease
 proposed herein for any reason is not approved by the Bankruptcy Court, then
 such executory contract or unexpired lease shall be deemed to have been
 rejected pursuant to the provisions of Section 4.4 below.

                  4.4  REJECTION.  Except for those executory contracts and
unexpired leases that are assumed pursuant to this Plan or that were previously
assumed or rejected by order of the Bankruptcy Court pursuant to Bankruptcy Code
section 365, as of the Effective Date, the Debtor in Possession shall reject,
pursuant to Bankruptcy Code section 365, all executory contracts and unexpired
leases.

                  4.5  APPROVAL OF REJECTION; REJECTION DAMAGES CLAIMS BAR DATE.
The Confirmation Order shall constitute an Order of the Bankruptcy Court
approving all rejections under Section 4.4 above of executory contracts and
unexpired leases pursuant to Bankruptcy Code section 365 as of the Effective
Date. Any Claim for damages arising from any such rejection must be Filed within
thirty (30) days after the later of mailing of notice of the entry of the
Confirmation Order or mailing of the notice of MPN's rejection of such contract
or lease, or such Claim shall be forever barred, shall not be enforceable
against the Debtor, its Estate, the Revested Debtor or any of their respective
properties and shall receive no distribution under the Plan or otherwise on
account of such Claim.

                                    ARTICLE 5

             MEANS FOR EXECUTION AND IMPLEMENTATION OF THE PLAN

                  5.1  VESTING OF PROPERTY OF THE ESTATE.  Except as otherwise
provided in the Plan or the Confirmation Order, on the Effective Date, any and
all property of the Estate shall vest in the Revested Debtor free and clear of
liens and encumbrances.

                  5.2  BUSINESS OF REVESTED DEBTOR.  From and after the
Effective Date, the business of the Revested Debtor shall consist of resolving
or prosecuting objections to Claims, liquidating any and all Assets of the
Estate to Cash, providing funds to the Disbursing Agent for


                                      -28-
<PAGE>   36
distributions to be made to Creditors as provided in Article 6 of this Plan,
taking any further actions that may be necessary to effectuate the terms of the
Settlement Agreement, the Supplemental Plan Agreement, and this Plan, including
pursuing enforcement or other remedies as may be necessary, and otherwise
winding up all affairs of the Estate. The Revested Debtor shall be authorized,
without further Bankruptcy Court approval, to employ, contract with,
compensate, release or terminate other persons, agents, employees, entities,
independent contractors, and attorneys, accountants and other professionals,
all as may be deemed necessary to assist in the performance of the duties of
the Revested Debtor hereunder.

         5.3  POST-EFFECTIVE DATE REPORTING.  As promptly as practicable after
the making of any distributions that are required under the Plan to be made on
the Effective Date, but in any event no later than five (5) Business Days after
the making of such distributions, MPN or the Disbursing Agent shall provide the
Reconstituted Committee with a report setting forth the amounts and timing of
all such distributions and the recipients thereof. Thereafter, the Revested
Debtor shall: (a) provide to the Reconstituted Committee quarterly reports
summarizing (i) the cash receipts and disbursements of the Revested Debtor for
the immediately preceding three-month period and (ii) the status of resolution
of any Disputed Claims during that same period. Each quarterly report shall
also state the Revested Debtor's cash balances, as well as any remaining
availability under the $40 Million LC, as of the beginning and ending of each
such period. Quarterly reports shall be provided no later than the fifteenth
(15th) day of each January, April, July and October until all Final
Distributions under the Plan have been made. In addition, MPN shall reasonably
promptly provide to the Reconstituted Committee such other additional
information that the Reconstituted Committee reasonably requires in connection
with carrying out its duties and obligations in connection with this Plan.

         5.4  MANAGEMENT OF REVESTED DEBTOR.  Exhibit "4" hereto designates the
Persons who will serve initially as directors of the Revested Debtor. If
necessary to fill vacancies at any time prior to the Effective Date, the Debtor
shall have the sole authority to make such designation or fill such vacancies.
All persons designated pursuant to this section shall be authorized to assume
their offices as of the Effective Date and to continue to serve in such


                                      -29-
<PAGE>   37
capacities thereafter pending further action of the Board of Directors or
stockholders of the Revested Debtor in accordance with applicable state law and
the Revested Debtor's then-applicable bylaws and charters. The Persons who are
officers of the Debtor as of the Effective Date shall assume their respective
offices of the Revested Debtor, subject to replacement by the directors of the
Revested Debtor. If the Revested Debtor fails to perform any obligations under
this Plan with respect to the making of any required payments or distributions,
the Reconstituted Committee may, upon notice and a hearing, seek Bankruptcy
Court authority and approval to take such actions as are necessary to fulfill
any such obligations on behalf of the Revested Debtor, including seeking the
designation by the Bankruptcy Court of an "Authorized Agent" (as defined in the
$40 million LC) on the terms and conditions and for the purposes set forth in
the $40 million LC, and may employ such experts as may be necessary to advise
the Reconstituted Committee with respect to such actions.

         5.5  FUNDING OF THE PLAN.  This Plan is a liquidating plan that
contemplates the distribution of all of the Assets of the Debtor to creditors
holding Allowed Claims, including all available Effective Date Cash and
Post-Effective Date Cash. In addition, Consenting Providers and Consenting
Plans shall be entitled to share in the funds made available as a result of the
subordination of the Class 3 Subordinated Claims and to be provided under the
MedPartners Funding Commitment, to the extent they hold Claims that qualify
therefor, in accordance with the terms and conditions of the Settlement
Agreement and the Supplemental Plan Agreement.

Accordingly:

                  (a)  With respect to distributions from the Estate, the
sources for distributions to be made under this Plan are as follows:

                           (i)      Effective Date Cash;

                           (ii)     Post-Effective Date Cash;

                           (iii)    To the extent the Operating Reserve, as
                                    supplemented by any Post-Effective Date Cash
                                    made available for such purposes, has been
                                    exhausted and there remain unpaid any (a)
                                    reasonable and necessary post-Effective Date
                                    expenses


                                      -30-

<PAGE>   38
                                   incurred by MPN or for which MPN is
                                   responsible, or (b) to the extent covered by
                                   the MedPartners Funding Commitment, any
                                   Unpaid Administrative Expense, MedPartners
                                   shall provide funds to satisfy such expenses;
                                   and

                          (iv)     To the extent any funds remain in the
                                   Operating Reserve after MPN has made payment
                                   in full of all amounts properly payable from
                                   the Operating Reserve under this Plan, such
                                   funds shall be available to MPN to distribute
                                   on account of any other payments required or
                                   permitted to be made under the Plan.

                 (b)  With respect to distributions under the MedPartners
Funding Commitment, the sources for distributions to be made under this Plan
are as follows:

                          (i)      the $40 Million LC; and

                          (ii)     additional funding to be provided by
                                   MedPartners, subject to the terms and
                                   conditions of the MedPartners Funding
                                   Commitment, but only to the extent necessary
                                   within the MedPartners Funding Commitment to
                                   (A) increase the amount of the Estate
                                   Distribution(s) on account of any particular
                                   Allowed Claim to 85% of the Allowed amounts
                                   of such Claim, (B) satisfy the MedPartners
                                   Funding Commitment with respect to Final
                                   Distributions, and (C) pay Unpaid
                                   Administrative Expenses and reasonable and
                                   necessary post-Effective Date expenses for
                                   which MPN is responsible.

        5.6  DRAWS ON $40 MILLION LC.  Prior to the Effective Date, MPN shall
calculate the nature and amount of the distributions and payments required to
be made under this Plan upon occurrence of the Effective Date and promptly
provide the Committee with such


                                      -31-

<PAGE>   39

information. On the Effective Date, MPN shall request a draw under the $40
Million LC in such amounts as are necessary to make such distributions and
payments to the extent this Plan provides that the $40 Million LC shall be a
source of funds available to make such distributions and payments.

         5.7  CONSENSUAL SUBORDINATION, WAIVER AND RELEASE OF CERTAIN CLAIMS.
In connection with the Plan, MPN, MedPartners, the Consenting MPI Subs, the
Consenting MPP's and the Consenting Plans have agreed to subordinate, waive or
release certain Claims on the terms and conditions set forth in the
Supplemental Plan Agreement. Upon occurrence of the Effective Date, MedPartners
shall also subordinate to, and only to, MPN Provider Claims that are or become
Allowed MPN Claims held by Consenting Providers or Consenting Plans and Plan
Preserved Claims that become Allowed MPN Claims held by Consenting Plans, any
Bankruptcy Code Section 503(b) Claim of MedPartners for unpaid post-Petition
Date amounts payable by MPN under the terms of the Management Agreement (as
that term is defined in the Settlement Agreement). In addition, by accepting
the MPN Provider Release provisions contained in Article 9 of this Plan,
Consenting Providers agree to subordinate certain Claims on the terms and
conditions set forth in Article 9. In accordance with Bankruptcy Code section
510(a), the distributions to Consenting Providers and Consenting Plans under
Section 6.12 hereof enforce and give effect to the subordinations, waivers and
releases contained in the Supplemental Plan Agreement and in the MPN Provider
Release. In order to receive the benefits of those subordinations, waivers
and/or releases, Providers, Health Plans and each of MedPartners and any of its
affiliates must agree to be bound by the releases and related provisions
contained in Article 9 of this Plan, as applicable to them, by timely executing
and delivering a ballot evidencing their respective agreement to do so.

         5.8  WAIVERS AND RELEASES BY MPN.  Except for the rights of MPN to
enforce the provisions of the Plan or the Supplemental Plan Agreement, effective
upon the Effective Date, MPN hereby (i) remises, acquits, waives, releases and
forever discharges each Consenting Plan and its successors, predecessors,
subsidiaries, affiliates, heirs and assigns, past and present officers,
directors, shareholders, employees, agents, attorneys, members and/or enrollees

(collectively, the "Consenting Plan Released Parties"), and (ii) covenants and
agrees never to institute or cause to be instituted any suit or other form of
action or proceeding of any kind or nature whatsoever against any of the
Consenting Plan Released Parties based upon any claims, demands, indebtedness,
agreements, promises, causes of action, obligations, damages or liabilities of
any nature whatsoever, in law or in equity, whether or not known, suspected or
claimed, that MPN or the Estate ever had, claimed to have, has, or may have or
claim to have against the Consenting Plan Released Parties, or any of them, by
reason of any matter, cause, thing, act or omission of the Consenting Plan
Released Parties, or any of them, in each case related to the California
Operations except for MPN Preserved Claims. All Claims so waived and released
shall be waived and released for purposes of (i) seeking affirmative relief and
(ii) defense of or setoff against MPN Plan Preserved Claims, including MPN
Provider Claims held by Consenting Plans, and shall be preserved only for
purposes of defense of, or setoff against, MPN Plan Subordinated Claims.

         Effective upon satisfaction of the MedPartners Funding Commitment, MPN
hereby (i) remises, acquits, waives, releases and forever discharges
MedPartners and its successors, predecessors, subsidiaries, affiliates, heirs
and assigns, past and present officers, directors, shareholders, employees,
agents and attorneys and every Managed Physician Practice (collectively, the
"MedPartners Released Parties"), and (ii) covenants and agrees never to
institute or cause to be instituted any suit or other form of action or
proceeding of any kind or nature whatsoever against any of the MedPartners
Released Parties based upon any claims, demands, indebtedness, agreements,
promises, causes of action, obligations, damages or liabilities of any nature
whatsoever, in law or in equity, whether or not known, suspected or claimed,
that MPN or the Estate ever had, claimed to have, has, or may have or claim to
have against the MedPartners Released Parties, or any of them, by reason of any
matter, cause, thing, act or omission of the MedPartners Released Parties, or
any of them, occurring at any time prior to the Effective Date.

         5.9  LIMITATION OF LIABILITY:  Except as expressly set forth in the
Plan, following the Effective Date, none of the Debtor, the Revested Debtor,

J. Mark Abernathy, in his capacity as Conservator and subsequently Special

Code section 1146(c), the issuance, transfer or exchange of any Security or the
making or delivery of any instrument of transfer under this Plan may not be
taxed under any law imposing a stamp tax or similar tax. Any sale of any Asset
occurring after the Effective Date shall be deemed to be in furtherance of this
Plan.

         5.12  PRESERVATION OF RIGHTS OF ACTION, SETOFFS AND RECOUPMENTS.
Except as otherwise provided in the Plan, the Supplemental Plan Agreement, the

Court, or any contract, instrument, release or other agreement entered into in
connection with the Plan, in accordance with the Bankruptcy Code section

account of such Allowed Claim, any and all of the Claims, causes of action and
rights of any nature that the Debtor, the Estate or the Revested Debtor may
hold against the holder of such Allowed Claim; provided, however, that neither
the failure to effect such a setoff or recoupment nor the allowance of any
Claim hereunder shall constitute a waiver of release by the Debtor, the Estate
or the Revested Debtor of any such Claims, causes of action or rights that the
Debtor, the Estate of the Revested Debtor may possess against such holder.
Except as otherwise provided in the Plan, the Supplemental Plan Agreement, the

the Bankruptcy Court, any settlement agreement or stipulation between MPN and a
Consenting Provider that has been approved by Final Order of the Bankruptcy

to setoff or recoup against an Allowed Claim and instead seeks to collect on a
Claim, cause of action or right against the holder of such Allowed Claim, the
Debtor or Revested Debtor shall be entitled to full recovery on their claim,
cause of action or right against such holder in accordance with applicable law.

Consenting Provider have not yet been finally resolved, whether by agreement or
pursuant to final judgment or final arbitration award either party to the
dispute may require the other party to participate in the binding arbitration
process set forth in Exhibit "5" hereto to resolve all such Claims, unless there
then exists a difference of $5 million or greater between the aggregate Claims
asserted against MPN by such Consenting Provider and the aggregate claims
asserted by MPN against such Consenting Provider ("Large Variance Creditors").
MPN will diligently prosecute legal proceedings to resolve all of its claims,

                                   ARTICLE 6

            DISTRIBUTIONS ON ACCOUNT OF ALLOWED CLAIMS AND INTERESTS

A.  DISTRIBUTIONS GENERALLY.

         6.1  DISTRIBUTIONS BY DISBURSING AGENT.  Distributions from funds
provided to the Disbursing Agent by MPN under this Plan shall be made by the
Disbursing Agent appointed by the Bankruptcy Court pursuant to the Confirmation
Order. The Disbursing Agent may


                                      -36-
<PAGE>   44
employ or contract with other entities to assist in or make the distributions
required by the Plan without further order of the Bankruptcy Court.

         6.2  DELIVERY OF DISTRIBUTIONS IN GENERAL.  Distributions to holders of
Allowed Claims shall be made: (a) at the addresses set forth in the Proofs of
Claim Filed by such holders; (b) at the addresses set forth in any written
notices of address change delivered to the Disbursing Agent after the date on
which any related Proof of Claim was Filed; or (c) at the addresses reflected
in the Schedules relating to the applicable Allowed Claim if no Proof of Claim
has been Filed and the Disbursing Agent has not received a written notice of a
change of address.

         6.3  CASH PAYMENTS.  Cash payments to be made pursuant to the Plan
shall be made by checks drawn on a domestic bank or by wire transfer from a
domestic bank, at the option of the Revested Debtor.

         6.4  NO DE MINIMIS DISTRIBUTIONS.   No payment of Cash in an amount of
less than $50.00 shall be made on account of any Allowed Claim.

         6.5  FACE AMOUNT.  For the purpose of the provisions of this Article
VI, the "face amount" of a Disputed Claim means the amount set forth on the
proof of claim unless the Disputed Claim has been estimated for distribution
purposes or, in the alternative, if no proof of claim has been timely Filed or
deemed Filed, zero.

         6.6  UNDELIVERABLE DISTRIBUTIONS.  If the distribution to any holder
of an Allowed Claim is returned to the Disbursing Agent as undeliverable, no
further distributions shall be made to such holder unless and until the
Disbursing Agent is notified in writing of such holder's then current address.
Undeliverable distributions shall remain in the possession of the Disbursing
Agent pursuant to this Plan in trust for the benefit of holders of Allowed
Claims until such time as a distribution becomes deliverable.

         Any holder of an Allowed Claim that does not assert a Claim pursuant
to the Plan for an undeliverable distribution to be made by the Disbursing
Agent within six (6) months after the date on which the distribution is
returned to the Disbursing Agent shall have its Claim for such undeliverable
distribution discharged and shall be forever barred from asserting any such
Claim for an undeliverable distribution against the Revested Debtor or its
property. In such


                                      -37-

<PAGE>   45
cases, any Cash held for distribution on account of such Claims for
undeliverable distributions shall become the property of the Estate and shall
be distributed in accordance with the terms of this Plan.

         6.7  COMPLIANCE WITH TAX REQUIREMENTS.  In connection with the Plan,
to the extent applicable, the Disbursing Agent shall comply with all tax
withholding and reporting requirements imposed on it by any governmental unit
and all distributions pursuant to the Plan shall be subject to such withholding
and reporting requirements. The Disbursing Agent shall be authorized to take
any and all actions that may be necessary or appropriate to comply with such
withholding and reporting requirements.

B.       DISTRIBUTIONS TO CLASSES OF CLAIMS.

         6.8  DISTRIBUTION TO CLASS 1A.  On the later of (a) the Effective
Date and (b) the tenth (10th) Business Day after the subject Secured Claim in
Class 1A becomes an Allowed Secured Claim, the Revested Debtor shall cause
holders of Allowed Secured Claims in Class 1A to receive one of the alternative
treatments set forth in Section 2.1.a above. To the extent the applicable
treatment is as set forth in Section 2.1.(a)(ii), any monetary defaults shall
be cured by the payment by the Revested Debtor of Cash in the full amount
necessary to effectuate such cure.

         6.9  DISTRIBUTION TO CLASS 1B.  The Revested Debtor shall cause to be
distributed to each holder of an Allowed Class 1B Claim Cash in the full amount
of such Allowed Claim upon the latest of: (i) the Effective Date, or as soon
thereafter as practicable; (ii) such date as may be fixed by the Bankruptcy
Court, or as soon thereafter as practicable; (iii) the tenth (10th) Business
Day after such claim is Allowed, or as soon thereafter as practicable; (iv) the
date on which such Secured Tax Claim is scheduled to be paid in the ordinary
course of business under applicable law or regulation; and (v) such date as the
holder of such Claim and the Debtor or Revested Debtor have agreed or shall
agree.

         6.10  DISTRIBUTION TO CLASS 1C.  On the later of (a) the Effective
Date and (b) the tenth (10th) Business Day after the subject Secured Claim in
Class 1C becomes an Allowed Secured Claim, the Revested Debtor shall cause
holders of Allowed Secured Claims in Class 1C to receive one of the alternative
treatments set forth in Section 2.1.c above. To the


                                      -38-
<PAGE>   46

extent the applicable treatment is as set forth in Section 2.1.c(ii), any
monetary defaults shall be cured by the payment by the Revested Debtor of Cash
in the full amount necessary to effectuate such cure. To the extent the
treatment is as set forth in Section 2.1.c(iii) above, the Revested Debtor
shall cause to be distributed to the holder of the Allowed Secured Claim Cash
in an amount equal to the amount of that Allowed Secured Claim, or in such
lesser amount as the holder of such Claim and the Revested Debtor shall agree,
in full satisfaction and release of such Claim.

         6.11  DISTRIBUTION TO CLASS 2.  On the later of the Effective Date or
the tenth (10th) Business Day after the subject Claim becomes an Allowed Claim,
the Revested Debtor shall cause to be distributed to each holder of an Allowed
Class 2 Claim Cash in the full amount of such Allowed Claim.

         6.12  DISTRIBUTION TO CLASS 3.

                  6.12.1  PRO RATA DISTRIBUTION ON ACCOUNT OF ALLOWED CLASS 3
CLAIMS.

On the Effective Date, after funding of the Operating Reserve, the
Administrative Claims Reserve and all Disputed Claims Reserves and payment of
or reserves on account of Administrative Claims, Priority Claims and any other
amounts required to be paid or reserved for on the Effective Date pursuant to
the terms of the Plan or the Confirmation Order and following the exercise of
all rights of setoff or recoupment of MPN with respect thereto in accordance
with the Supplemental Plan Agreement, the Bankruptcy Court's order approving
the Supplemental Plan Agreement or 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, the
Revested Debtor shall cause to be distributed to each holder of an Allowed
Claim in Class 3 Cash in an amount equal to such holder's Pro Rata share of all
of the Revested Debtor's Cash on hand, including all Net Cash Proceeds in the
MPN California Account but excluding any amounts provided under the MedPartners
Funding Commitment.


                                      -39-
<PAGE>   47
                  6.12.2  DISTRIBUTIONS ON ACCOUNT OF ALLOWED CLASS 3A AND
ALLOWED CLASS 3B CLAIMS HELD BY CONSENTING PROVIDERS AND CONSENTING PLANS.

                           6.12.2.1  STIPULATED CLAIMS AMOUNT AND STIPULATED
ESTATE VALUE.  For purposes of making distributions from the Estate and
calculating reserves thereon as of the Effective Date, the Confirmation Order
shall establish the Stipulated Claims Amount in a maximum amount of $80 million
and the Stipulated Estate Value in a minimum amount of $38 million, provided,
however, that the Stipulated Estate Value shall be reduced on a dollar-for-
dollar basis to the extent that as of the Effective Date (i) MPN has realized
less than $4 million from Retro Rate Recoveries, and (ii) Tangible Asset
Recoveries realized by MPN and the net appraised value of Tangible Assets
for which sales have not yet closed is less than $13 million in the aggregate.

                           6.12.2.2  INITIAL ESTATE DISTRIBUTIONS.  An initial
distribution of property of the MPN estate will be made to each holder of an
MPN Provider Claim or MPN Plan Preserved Claim that is or becomes an Allowed
Claim that is eligible for the benefits of the MedPartners Funding Commitment
(the "Initial Estate Distribution"):

         (a)      with respect to a Claim that becomes an Allowed Claim on or
before the Confirmation Date, as soon as practicable after the Effective Date
in an amount equal to the product of the amount of such Allowed Claim
multiplied by a fraction, the numerator of which is the Stipulated Estate
Value and the denominator of which is the Stipulated Claim Amount (such
fraction defined as the "Distribution Ratio"); and

         (b)      with respect to a Claim that becomes such an Allowed Claim
after the Confirmation Date, within ten (10) days after the end of the calendar
month in which such Claim becomes an Allowed Claim in an amount equal to the sum
of (i) from the Disputed Claim Reserve, an amount equal to the product of the
amount of such Allowed Claim multiplied by the Distribution Ratio, and (ii)
after giving effect to (i), from any then available Post-Effective Date Cash,
after reserving for distributions on account of Allowed Claims and Disputed
Claims that are not eligible for MedPartners Funding Commitment and such
amounts as are necessary to satisfy post-Effective Date expenses for which MPN
is responsible and which are not covered by


                                      -40-
<PAGE>   48

the MedPartners Funding Commitment, such amount as is necessary to enable such
holder to receive the same percentage distribution on account of such Allowed
Claim as has already been received by the holders of previously allowed Allowed
Claims eligible for the benefits of the MedPartners Funding Commitment on
account of such Allowed Claims pursuant to an Initial Estate Distribution, any
Supplemental Estate Distributions and any distributions under the $40 Million
LC or from MedPartners pursuant to the MedPartners Funding Commitment.

         With respect to the Initial Estate Distribution and any distributions
required to be made concurrently therewith from funds to be provided by
MedPartners under the MedPartners Funding Commitment (including from any draws
made under the $40 Million LC) on account of the Allowed Claims that are
Allowed on or before the Confirmation Date, MPN and MedPartners, as applicable,
shall provide the funds necessary to make such distributions to the Disbursing
Agent no later than two (2) business days following the Effective Date.

                           6.12.2.3  SUPPLEMENTAL ESTATE DISTRIBUTIONS.  To the
extent MPN accumulates Post-Effective Date Cash in an amount totaling at least
$3,000,000, after all distributions and reserves made pursuant to Section
6.12.2.2 above, the use of which is not restricted under this Plan or, once
the Operating Reserve has been exhausted, not required to pay reasonable and
necessary post-Effective Date costs and expenses, and such funds are available
for the payment of Allowed Claims, MPN shall make subsequent distributions of
such funds to each holder of an Allowed Class 3 Claim in such a manner as to
provide: (a) prepetition creditors other than consenting Providers and
Consenting Providers and Consenting Plans with their pro rata share of the
Assets of MPN's Estate, and (b) Consenting Providers and Consenting Plans with
equal percentage distributions on account of their Allowed Claims that are
covered by the MedPartners Funding Commitment that in no event exceed the
amounts necessary to satisfy the MedPartners Funding Commitment with respect to
such Allowed Claims (each a "Supplemental Estate Distribution" and together
with the Initial Estate Distribution for such claimant, the "Estate
Distribution"); provided, however, that: (x) to the extent the MedPartners
Funding Commitment has been satisfied with respect to any Allowed Claim of any
Consenting Provider or Consenting Plan on or before the date a Supplemental
Estate Distribution is to be made, such Consenting


                                      -41-
<PAGE>   49
Provider or Consenting Plan shall not participate in such Supplemental Estate
Distribution on account of such Allowed Claim; and (y) in no event shall any
Consenting Provider that elects the 90% Cash Election participate in any
Supplemental Estate Distribution.

         Each Supplemental Estate Distribution will be subject to a reserve for
Disputed Claims to be calculated based upon: (x) the Stipulated Claims Amount,
which shall be (i) increased on a dollar-for-dollar basis to the extent that
Allowed Claims that are covered by the MedPartners Funding Commitment exceed $80
million, or (ii) decreased on a dollar-for-dollar basis to the extent that the
sum of Allowed Claims that are covered by the MedPartners Funding Commitment
plus the face amount of Disputed Claims that are covered by the MedPartners
Funding Commitment is less than $80 million; and (y) following resolution of all
disputes and Allowance of any previously Disputed Claim (the "Resolved Disputed
Claim"), reduction of the reserve by a percentage equal to the percentage that
the Resolved Disputed Claim was to the face amount of all Disputed Claims as of
the Effective Date, each as calculated prior to the date of the Supplemental
Estate Distribution.

                           6.12.2.4 DISTRIBUTIONS FROM THE FUNDS DRAWN UNDER
THE $40 MILLION LC.  The $40 Million LC will be drawable in accordance with its
terms to make distributions on account of Allowed Claims of Consenting Providers
and Consenting Plans covered by the MedPartners Funding Commitment, without any
reserve whatsoever. Except in connection with Final Distributions as set forth
in Section 6.1.2.2.7 below, such distributions will be made concurrently with,
or promptly following the payment of, the Initial Estate Distribution, provided
that the maximum amount drawn under the $40 million LC to be paid to any
claimant shall be the amount necessary to increase the Initial Estate
Distribution and all other Estate Distributions made contemporaneously therewith
to 85% of the Allowed Claim with respect to which payment is being made (or 90%
if the holder has elected the 90% Cash Election).

                           6.12.2.5  THE 85% DISTRIBUTION.  To the extent funds
distributed from the Initial Estate Distribution, any concurrent Supplemental
Estate Distribution(s) and the $40 Million LC do not result in an 85%
Distribution on account of any Allowed Claim covered by the MedPartners Funding
Commitment (or 90% if the holder has elected the 90% Cash

                                      -42-
<PAGE>   50
Election), pursuant to the MedPartners Funding Commitment MedPartners shall
make available such funds as are necessary to increase the aggregate amount
distributed on account of such Claim to 85% of the amount of such Allowed Claim
that is covered by the MedPartners Funding Commitment in such a manner as to
enable such distributions to be made timely (or 90% if the holder has elected
the 90% Cash Election). (The total distributions to be made pursuant to
Sections 6.12.2.2, 6.12.2.3, 6.12.2.4 and 6.12.2.5 are referred to collectively
as the "85% Distribution.") The Disbursing Agent may not make any distributions
on account of any portion of an 85% Distribution (or 90% Distribution, if
applicable), however, unless the Disbursing Agent is making distributions to
satisfy such 85% Distribution (or 90% Distribution, if applicable) in full, as
a result of which the releases provided for in Sections 9.1, 9.3.1, 9.3.2, 9.4
and 9.6 of this Plan, as applicable, shall become effective pursuant to their
terms and conditions.

                           6.12.2.6  FINAL DISTRIBUTIONS.  Subject to the
provisions of this Section 6.12.2.6, as soon as practicable after the date that
is one year following the date the 85% Distribution is complete with respect to
an Allowed Claim, a final distribution (the "Final Distribution") shall be made
on account of such Allowed Claim in the amount necessary to satisfy the
MedPartners Funding Commitment with respect to the Allowed Claim on account of
which payment is being made. The Final Distribution shall be made from the
following sources and in the following order: (a) out of that portion of the
Assets of the MPN Estate available after reserving for Disputed Claims; (b)
from draws made on the $40 Million LC until fully drawn; and (c) from funds
provided by MedPartners pursuant to the MedPartners Funding Commitment, if
necessary. In no event shall any Consenting Provider that elects the 90% Cash
Election participate in or receive any Final Distribution(s).

         As a prerequisite for making Final Distributions, MPN shall promptly
and diligently pursue resolution of all such claims in anticipation of
obtaining final resolution of any and all claims, whether such claims
constitute Permitted Expenses (as defined in the Settlement Agreement) or
expenses that are not eligible for the benefits of the MedPartners Funding
Commitment; provided, however, that if any such claims that are not eligible
for the benefits of the MedPartners Funding Commitment are not resolved at the
time a Final Distribution is due in

                                      -43-
<PAGE>   51

accordance with the immediately preceding paragraph, an interim distribution on
account of the Final Distribution shall be made, calculated (a) based upon the
total amount of all such Claims that are undisputed or have been finally
resolved, and (b) assuming for distribution purposes only that the disputed
amount of any such Claims represent expenses that must be paid by the Estate
but are not covered by the MedPartners Funding Commitment (such that funds
equal to any such disputed amounts shall be withheld from the amount
distributed under any such interim distribution on account of the Final
Distribution). The balance of the Final Distribution will be paid as soon as is
practicable following the final resolution of all such claims.

                           6.12.2.7  DISTRIBUTIONS TO MEDPARTNERS.  Once the
MedPartners Funding Commitment has been satisfied in full with respect to MPN
(including reasonable and necessary post-Effective Date expenses incurred by
MPN or for which MPN is responsible and Unpaid Administrative Expenses, to the
extent such items are covered by the MedPartners Funding Commitment) and all of
the voluntary subordinations provided for in the Settlement Agreement, the
Supplemental Plan Agreement and Articles 2, 5 and 9 of this Plan have otherwise
been effectuated, any distributions that otherwise would be made to Consenting
Providers or Consenting Plans instead shall be made to MedPartners until such
time as MedPartners has been reimbursed in full for all funds provided by it
under the MedPartners Funding Commitment, whether under the $40 Million LC or
otherwise.

                           6.12.2.8  DISTRIBUTIONS TO CONSENTING PLANS.  Any and
all payments to be made by MPN to any Consenting Plan shall be made in the same
manner, timing and percentage amounts as payments to be made to Consenting
Providers, subject to Section 20.18 of the Supplemental Plan Agreement or any
other agreement between MPN and a Consenting Plan that modifies the Supplemental
Plan Agreement as to those parties and has been approved by Final Order of the
Bankruptcy Court.

         6.13  DISPUTED CLAIMS RESERVES.  To the extent there exist as of the
Effective Date Disputed Claims in any Class, the Revested Debtor shall reserve
from any distribution of Estate Assets Cash in an amount equal to whatever Cash
distribution the holder(s) of such Disputed Claim(s) would be entitled to
receive if the face amount of such Claim(s) became an


                                      -44-
<PAGE>   52

Allowed Claim in that Class (and with respect to Class 3, based upon the
Stipulated Claims Amount). To the extent that any such Disputed Claim becomes
an Allowed Claim, such reserved Cash shall be distributed to the holder of the
Allowed Claim in a manner and amount consistent with the treatment of Allowed
Claims in that Class, with any surplus Cash becoming generally available for
use by the Revested Debtor in accordance with the terms of this Plan; provided,
however, that distributions made under the MedPartners Funding Commitment shall
not be subject to any such reserves.

         6.14  DISBURSEMENT OF RESIDUAL FUNDS TO MEDPARTNERS.  To the extent
funds made available to the Debtor pursuant to the MedPartners Funding
Commitment exceed the amount necessary for the satisfaction of Allowed Claims
entitled to receive the benefits of the MedPartners Funding Commitment, such
excess funds shall be treated in the manner set forth in section 3.5(d) of the
Settlement Agreement.

hereafter have or claim to have against MPN by reason of any matter, cause,
thing, act or omission of MPN occurring at any time prior to the date of
payment of such 85% Distribution.

         9.7  RELEASE OF MPN BY MEDPARTNERS RELEASING PARTIES UPON RECEIPT OF

time prior to the date of payment of the Final Distribution.

         9.8  FURTHER AGREEMENTS OF PROVIDERS AND PLANS.

                  9.8.1  Each releasing party under this Article 9 further
understands and agrees that the releases granted pursuant to this Article 9
will be treated as a full and complete defense to, and will forever be a
complete bar to the commencement or prosecution of any and

                                      -56-
<PAGE>   64
all causes of action arising out of any matter, cause or thing whatsoever
whenever arising which may be brought, instituted or taken by the releasing
parties against the released parties arising out of the circumstances of any
claims released hereunder.

                  9.8.2  Each releasing party under this Article 9 understands
and agrees that there is a risk that subsequent to the date the releases under
this Article 9 becomes effective, such releasing party will discover, incur or
suffer claims or causes of action that were unknown or unanticipated at the time
those releases became effective, including but not limited to unknown or
unanticipated claims or causes of action that arose from, or are based upon or
relate to, the claims hereby released that if known by such releasing party on
the date the releases under this Article 9 became effective may have materially
affected said releasing party's decision to consent and agree to such release.
Each releasing party understands that when it consents and agrees to the
releases granted pursuant to this Article 9, it is assuming the risk of such
unknown claims or causes of action and agrees that its release of the released
parties applies to any and all such claims and causes of action.

                  9.8.3  Each releasing party, by consenting and agreeing to the
releases granted pursuant to this Article 9, represents that it has read the
Plan, including this Article 9 and fully understands all of its terms; that it
has made such factual investigation pertaining to the releases granted pursuant
to this Article 9, as it deems necessary; that it has been advised to confer
with its attorney prior to agreeing to the releases granted pursuant to this
Article 9, and that it has so conferred or has knowingly and voluntarily chosen
not to confer with an attorney; that it understands any rights it may have and
agrees to the releases granted pursuant to this Article 9, with full knowledge
of any such rights; and that the released parties have not made any statement or
representation to such releasing party regarding any fact relied upon in
entering into the releases granted pursuant to this Article 9, except as
expressly stated in this Plan, Disclosure Statement or the Settlement Agreement.

                  9.9  ACKNOWLEDGMENT OF RELEASE.  With respect to any general
releases granted under this Plan, each releasing party thereunder understands
and agrees that it is releasing unknown claims and expressly waives all rights
it has or may have under Section 1542 of the


                                      -57-

<PAGE>   65

California Civil Code or any other statute or common law principle of similar
effect. Each such releasing party acknowledges that it is familiar with Section
1542 of the California Civil Code, which reads as follows:

         A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES
         NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE
         RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS
         SETTLEMENT WITH THE DEBTOR.

         9.10  OTHER RESTRICTIONS AGREED TO BY PROVIDER.

                  9.10.1  Except as provided in Section 9.3.3, Provider
explicitly agrees not to bill, initiate any action, or otherwise seek payment
on account of any MPN Provider Claims for Health Care Services from enrollees
of any Consenting Plan.

                  9.10.2  In consideration of the tolling agreements contained
in the Supplemental Plan Agreement in favor of Providers, Provider explicitly
agrees to refrain from seeking payment from any Consenting Plan Released Party
or initiating any action against any Consenting Plan Released Party related to
any MPN Provider Claims unless and until the first to occur of (i) the one
hundred eightieth day after a judgment has been rendered that a payment default
has occurred in the payment of an 85% Distribution or a 90% Distribution, as
applicable, to a Provider pursuant to an arbitration proceeding under Article
12 of the Settlement Agreement or a judicial proceeding pursuant to Section
10.4 or 16.14 of the Settlement Agreement, if such 85% Distribution or 90%
Distribution, as applicable, are not then being made in accordance with this
Plan; (ii) the earliest date after such one hundred eightieth day that the
payment of an 85% Distribution or a 90% Distribution, as applicable to a
Provider is not being made in accordance with this Plan; and (iii) a case under
the Bankruptcy Code has been filed by or against MedPartners.


                                      -58-

<PAGE>   66

                  9.10.3  In consideration of the tolling agreements contained
in the Supplemental Plan Agreement in favor of Providers, Provider explicitly
agrees to refrain from seeking payment from or initiating any action against
any MedPartners Released Party unless and until a payment default has occurred
under this Plan with respect to any distributions to be made to such Provider.

                  9.10.4  If Provider previously contracted with MPN to provide
institutional services and is recontracting for the provision of such services
directly with a Plan, then, in connection with such initial transfer of
institutional risk from MPN to the Consenting Plans, Provider expressly
acknowledges that it has offered, or agrees to offer on a retroactive basis,
the Consenting Plans, in good faith, economic contract terms which are no less
favorable than MPN received from such Provider immediately prior to the
transfer of such institutional risk to the Consenting Plans through the earlier
to occur of December 31, 1999 or the expiration of such Provider's contract
with MPN.

         9.11  SUBORDINATION OF OTHER CLAIMS.  Provider hereby agrees to
subordinate any Claims of Provider other than MPN Provider Claims to, and only
to, MPN Provider Claims and Plan Preserved Claims that become Allowed Claims
held by Consenting Providers or Consenting Plans. Provider also agrees that any
distribution to which it otherwise would be entitled on account of such
subordinated Claims shall be and hereby is assigned for the benefit of the
Consenting Providers and Consenting Plans on account of their MPN Provider
Claims and Plan Preserved Claims that become Allowed MPN Claims in the manner
set forth, and on the terms and conditions of, Articles 2, 5 and 6 of this Plan.

         9.12  ACKNOWLEDGMENT OF THIRD PARTY BENEFICIARY RIGHTS.  To the extent
Provider may be a Beneficiary as defined in the Settlement Agreement, Provider
consents to the scope of Provider's rights provided in Section 16.14 thereof,
particularly as to the jurisdictional threshold for enforcement (Section
16.14(c)) and as to notice (Section 16.14(d)).

         9.13  SUCCESSORS AND ASSIGNS.  The Releases granted pursuant to this
Article 9 shall bind and inure to the benefit of the respective heirs, legal
representatives, successors and assigns of each Consenting Provider.

<PAGE>   67

         9.14  NO IMPAIRMENT OF CONSENTING PLAN'S RIGHTS TO ENFORCE THE
SUPPLEMENTAL PLAN AGREEMENT OR ANY SUBSEQUENT SETTLEMENT AGREEMENT AGAINST
MPN.  Except as it pertains to the satisfaction and release of Allowed Claims
against MPN held by Consenting Plans, nothing in this Article 9 shall impair
the rights of any Consenting Plan (including any rights of such Consenting Plan
upon a breach thereof) with respect to the Settlement Agreement, the
Supplemental Plan Agreement or any other agreement between MPN and such
Consenting Plan that (a) modifies the Supplemental Plan Agreement and (b) has
been approved by Final Order of the Bankruptcy Court, subject to the terms and
conditions of the applicable governing agreement.

         9.15  PRESERVATION OF BANKRUPTCY CODE SECTION 503(B) CLAIMS.

         Notwithstanding anything to the contrary in this Article 9, nothing
contained in this Article 9 shall constitute a waiver, release or subordination
of any Claim under Bankruptcy Code section 503(b).


                                   ARTICLE 10

                           RETENTION OF JURISDICTION

                            MISCELLANEOUS PROVISIONS

         11.1  REQUEST FOR NON-CONSENSUAL CONFIRMATION.  To the extent each
Impaired Class of Claims or Interests does not vote to accept the Plan, the
Debtor requests that the Court confirm the Plan under the cramdown provisions
of Bankruptcy Code section 1129(b).

         11.2  POST-EFFECTIVE DATE OVERSIGHT OF THE REVESTED DEBTOR.  On the
Effective Date, the Committee shall be reconstituted to consist of four (4)
members, two (2) of whom shall be selected by the Providers or Provider
representatives serving on the Committee as of the Confirmation Date and two (2)
of whom shall be selected by the Health Plans serving on the Committee as of the
Confirmation Date (the "Reconstituted Committee"). The Reconstituted Committee
shall be authorized to employ one law firm as counsel (unless such law firm is
unable to represent the Reconstituted Committee with respect to a particular
matter, in which case a separate law firm may be employed sole to handle that
particular matter), which firm (or firms)


                                      -62-
<PAGE>   70
shall be entitled to compensation from the Operating Reserve. The Reconstituted
Committee shall be authorized to employ Crossroads, LLC as its financial
advisor through the end of the calendar month immediately following the
calendar month during which the Effective Date occurs. Crossroads, LLC shall be
entitled to compensation from the Operating Reserve. The Reconstituted
Committee and its advisors shall be authorized solely to oversee distributions
under this Plan and to exercise those remedies available to the Reconstituted
Committee under this Plan or the Committee under the Settlement Agreement;
provided, however, that if the Revested Debtor fails to perform any material
obligations under this Plan, the Reconstituted Committee may, upon notice and a
hearing, seek a Bankruptcy Court order to enforce the provisions of the Plan and
may employ such experts as may be necessary to advise the Reconstituted
Committee with respect to such action.

         11.3  TERMINATION OF EXAMINER ORDER.  On the Effective Date, the
Examiner Order shall terminate and be of no further force or effect.

         11.4  MODIFICATION OF THE PLAN.  Subject to the restrictions on plan
modifications set forth in Bankruptcy Code section 1127, the Debtor and the
Revested Debtor reserve the right to alter, amend or modify the Plan before its
substantial consummation.

         11.5  REVOCATION OF THE PLAN.  The Debtor reserves the right to revoke
or withdraw the Plan prior to the Confirmation Date. If the Debtor revokes or
withdraws the Plan, or if Confirmation does not occur or if the Plan odes not
become effective, then the Plan shall be null and void, and nothing contained
in the Plan shall: (a) constitute a waiver or release of any Claims by or
against, or any Interests in, the Debtor; (b) constitute an admission of any
fact or legal conclusion by the Debtor or any other Entity; or (c) prejudice in
any manner the rights of the Debtor in any further proceedings involving the
Debtor.

         11.6  AMENDMENT OF THE SETTLEMENT AGREEMENT.  The Settlement Agreement
shall not be amended after the Confirmation Date in any manner that is adverse
to the interests of MPN, the Estate, Consenting Plans or Consenting Providers
unless the Bankruptcy Court shall have approved such amendment following notice
and a hearing.


                                      -63-
<PAGE>   71

         11.7  GOVERNING LAW.  Unless a rule of law or procedure is supplied by
(i) federal law (including the Bankruptcy Code and Bankruptcy Rules), or (ii)
an express choice of law provision in any agreement, contract, instrument or
document provided for, or executed in connection with, the Plan, the rights and
obligations arising under the Plan and any agreements, contracts, documents and
instruments executed in connection with the Plan shall be governed by, and
construed and enforced in accordance with, the laws of the State of California
without giving effect to the principles of conflict of laws thereof.

         11.8  NO ADMISSIONS.  Notwithstanding anything herein to the contrary,
nothing contained in the Plan shall be deemed as an admission by the Debtor
with respect to any matter set forth herein including, without limitation,
liability on any Claim or the propriety of any Claims classification.

         11.9  SEVERABILITY OF PLAN PROVISIONS.  If prior to Confirmation any
term or provision of the Plan that does not govern the treatment of Claims or
Interests is held by the Bankruptcy Court to be invalid, void or unenforceable,
the Bankruptcy Court shall have the power to alter and interpret such term or
provision to make it valid or enforceable to the maximum extent practicable,
consistent with the original purpose of the term or provision held to be
invalid, void or unenforceable, and such term or provision shall then be
applicable as altered or interpreted. Notwithstanding any such holding,
alteration or interpretation, the remainder of the terms and provisions of the
Plan shall remain in full force and effect and shall in no way be affected,
Impaired or invalidated by such holding, alteration or interpretation. The
Confirmation Order shall constitute a judicial determination and shall provide
that each term and provision of the Plan, as it may have been altered or
interpreted in accordance with the foregoing, is valid and enforceable pursuant
to its terms.

         11.10  SUCCESSORS AND ASSIGNS.  The rights, benefits and obligations of
any Entity named or referred to in the Plan shall be binding on, and shall
inure to the benefit of, any heir, executor, administrator, successor or assign
of such Entity.

         11.11  SATURDAY, SUNDAY OR LEGAL HOLIDAY.  If any payment or act under
the Plan is required to be made or performed on a date that is not a Business
Day, then the making of

                                      -64-

<PAGE>   72
such payment or the performance of such act may be completed on the next
succeeding Business Day, but shall be deemed to have been completed as of the
required date.

         11.12  NO DIMINISHMENT OF MEDPARTNERS FUNDING COMMITMENT.  Neither the
Plan nor the Confirmation Order shall diminish the MedPartners Funding
Commitment as it applies to: (a) holders of Managed Physician Practice Provider
Claims; or (b) Consenting Plans insofar as they hold Managed Physician Practice
Provider Claims or Plan Preserved Claims against a Managed Physician Practice.

         11.13  NO PRECLUSIVE EFFECT.  The failure of a party to object to
anything contained in or omitted from the Disclosure Statement shall not be
deemed to be acquiescence to the accuracy or adequacy of such matter, or in any
other manner act as a waiver or estoppel in any other existing or future
litigation.
