         on the business day immediately preceding the date of reference, unless
         the Committee or the Board in its sole discretion shall determine

         price of Common Stock on such system or, if sales prices are not

         officer," the person so identified shall be deemed an "Officer" even

         corporations other than the last corporation in the unbroken chain owns
         stock possessing 50 percent or more of the total combined voting power
         of all classes of stock in one of the other corporations in such chain.

         3. SHARES AVAILABLE FOR OPTION GRANTS. The Committee or the Board may
grant to Optionees from time to time Options to purchase an aggregate of up to
Three Million (3,000,000) Shares from the Company's authorized and unissued
Shares; provided, however, in no event shall the Board or the Committee grant
Options to purchase more than 5% of the Company's outstanding Shares in any one
year. If any Option granted under the Plan shall terminate, expire, or be
canceled or surrendered as to any Shares, new Options may thereafter be granted
covering such Shares.

         4.       CONDITIONS FOR GRANT OF OPTIONS.

                  (a) Each Option shall be evidenced by an Option Agreement that
may contain any term deemed necessary or desirable by the Committee or the
Board, provided such terms are not inconsistent with this Plan or any applicable
law. Optionees shall be those persons selected by the Committee or the Board
from the class of all regular employees of the Company or its Subsidiaries.

                  (b) In granting Options, the Committee or the Board shall take
into consideration the contribution the person has made to the success of the
Company or its Subsidiaries and such other factors as the Committee or the Board
shall determine. The Committee or the Board shall also have the authority to
consult with and receive recommendations from officers and other personnel of
the Company and its Subsidiaries with regard to these matters. The Committee or
the Board may from time to time in granting Options under the Plan prescribe
such other terms and conditions concerning such Options as it deems appropriate,
including, without limitation, (i) prescribing the date or dates on which the
Option becomes exercisable, (ii) providing that the Option rights accrue or
become exercisable in installments over a period of years, or upon the
attainment of stated goals or both, or (iii) relating an Option to the continued
employment of the Optionee for a specified period of time, provided that such
terms and conditions are not more favorable to an Optionee than those expressly
permitted herein.

                                       3
<PAGE>   4

         5. OPTION PRICE. The option price per Share of any Option shall be any
price determined by the Committee or the Board but shall not be less than the
par value per Share.

         6. EXERCISE OF OPTIONS. An Option shall be deemed exercised when (i)
the Company has received written notice of such exercise in accordance with the
terms of the Option, (ii) full payment of the aggregate option price of the
Shares as to which the Option is exercised has been made, and (iii) arrangements
that are satisfactory to the Committee or the Board in its sole discretion have
been made for the Optionee's payment to the Company of the amount that is
necessary for the Company or Subsidiary employing the Optionee to withhold in
accordance with applicable Federal or state tax withholding requirements. The
consideration to be paid for the Shares to be issued upon exercise of an Option
as well as the method of payment of the exercise price and of any withholding
and employment taxes applicable thereto, shall be determined by the Committee or
the Board and may in the discretion of the Committee or the Board consist of:
(1) cash, (2) certified or official bank check, (3) money order, (4) Shares that
have been held by the Optionee for at least six (6) months (or such other Shares
as the Company determines will not cause the Company to recognize for financial
accounting purposes a charge for compensation expense), (5) the withholding of
Shares issuable upon exercise of the Option, (6) pursuant to a "cashless
exercise" procedure, by delivery of a properly executed exercise notice together
with such other documentation, and subject to such guidelines, as the Board or
the Committee shall require to effect an exercise of the Option and delivery to
the Company by a licensed broker acceptable to the Company of proceeds from the
sale of Shares or a margin loan sufficient to pay the exercise price and any
applicable income or employment taxes, or (7) in such other consideration as the
Committee or the Board deems appropriate, or by a combination of the above. The
Committee or the Board in its sole discretion may accept a personal check in
full or partial payment of any Shares. If the exercise price is paid, and/or the
Optionee's tax withholding obligation is satisfied, in whole or in part with
Shares, or through the withholding of Shares issuable upon exercise of the
Option, the value of the Shares surrendered or withheld shall be their Fair
Market Value on the date the Option is exercised. The Committee or the Board in
its sole discretion may, on an individual basis or pursuant to a general program
established in connection with this Plan, cause the Company to lend money to an
Optionee, guarantee a loan to an Optionee, or otherwise assist an Optionee to
obtain the cash necessary to exercise all or a portion of an Option granted
hereunder or to pay any tax liability of the Optionee attributable to such
exercise. If the exercise price is paid in whole or part with Optionee's
promissory note, such note shall (i) provide for full recourse to the maker,
(ii) be collateralized by the pledge of the Shares that the Optionee purchases
upon exercise of the Option, (iii) bear interest at the prime rate of the
Company's principal lender, and (iv) contain such other terms as the Committee
or the

                                       4
<PAGE>   5

Board in its sole discretion shall reasonably require. No Optionee shall be
deemed to be a holder of any Shares subject to an Option unless and until a
stock certificate or certificates for those Shares are issued to that person(s)
under the terms of this Plan. No adjustment shall be made for dividends
(ordinary or extraordinary, whether in cash, securities or other property) or
distributions or other rights for which the record date is prior to the date the
stock certificate is issued, except as expressly provided in Section 9 hereof.

         7. EXERCISABILITY OF OPTIONS. Any Option shall become exercisable in
such amounts, at such intervals and upon such terms as the Committee or the
Board shall provide in the Option Agreement for that Option, except as otherwise
provided in this Section 7:

                  (a) The expiration date of an Option shall be determined by
the Committee or the Board at the time of grant, but in no event shall an Option
be exercisable after the expiration of 10 years from the date of grant of the
Option.

                  (b) Unless otherwise provided in any Option, each outstanding
Option shall become immediately fully exercisable in the event of a "Change in
Control" or in the event that the Committee or the Board exercises its
discretion to provide a cancellation notice with respect to the Option pursuant
to Section 8(b) hereof. For this purpose, the term "Change in Control" shall
mean:

                           (i) Approval by the shareholders of the Company of a
reorganization, merger, consolidation or other form of corporate transaction or
series of transactions, in each case, with respect to which persons who were the
shareholders of the Company immediately prior to such reorganization, merger or
consolidation or other transaction do not, immediately thereafter, own more than
50% of the combined voting power entitled to vote generally in the election of
directors of the reorganized, merged or consolidated company's then outstanding
voting securities, in substantially the same proportions as their ownership
immediately prior to such reorganization, merger, consolidation or other
transaction, or a liquidation or dissolution of the Company or the sale of all
or substantially all of the assets of the Company (unless such reorganization,
merger, consolidation or other corporate transaction, liquidation, dissolution
or sale is subsequently abandoned); or

                  (c) The Committee or the Board may in its sole discretion,
accelerate the date on which any Option may be exercised and may accelerate the
vesting of any Shares subject to any Option or previously acquired by the
exercise of any Option.

         8.       TERMINATION OF OPTION PERIOD.

                  (a) Unless otherwise provided in any Option Agreement, the
unexercised portion of any Option shall automatically and without notice
terminate and become null and void at the time of the earliest to occur of the
following:

                                       5
<PAGE>   6

                           (i) three months after the date on which the
Optionee's employment is terminated other than by reason of (A) Cause, which,
solely for purposes of this Plan, shall mean the termination of the Optionee's
employment by reason of the Optionee's willful misconduct or gross negligence,
(B) a mental or physical disability (within the meaning of Internal Revenue Code
Section 22(e)) of the Optionee as determined by a medical doctor satisfactory to
the Committee, or (C) death of the Optionee;

                           (ii) immediately upon the termination of the
Optionee's employment for Cause;

                           (iii) twelve months after the date on which the
Optionee's employment is terminated by reason of a mental or physical disability
(within the meaning of Section 22(e) of the Code) as determined by a medical
doctor satisfactory to the Committee or the Board;

                           (iv) (A) twelve months after the date of termination
of the Optionee's employment by reason of death of the Optionee, or, if later,
(B) three months after the date on which the Optionee shall die if such death
shall occur during the one year period specified in Subsection 8(a)(iii) hereof;
or

                           (v) the tenth anniversary of the date of grant of the
Option.

All references herein to the termination of the Optionee's employment shall, in
the case of an Optionee who is not an employee of the Company or a Subsidiary,
refer to the termination of the Optionee's service with the Company.

                  (b) To the extent not previously exercised, (i) each Option
shall terminate immediately in the event of (1) the liquidation or dissolution
of the Company, or (2) any reorganization, merger, consolidation or other form
of corporate transaction in which the Company does not survive, unless the
successor corporation, or a parent or subsidiary of such successor corporation,
assumes the Option or substitutes an equivalent option or right pursuant to
Section 9(c) hereof, and (ii) the Committee or the Board in its sole discretion
may by written notice ("cancellation notice") cancel, effective upon the
consummation of any corporate transaction described in Subsection 7(b)(i) hereof
in which the Company does survive, any Option that remains unexercised on such
date. The Committee or the Board shall give written notice of any proposed
transaction referred to in this Section 8(b) a reasonable period of time prior
to the closing date for such transaction (which notice may be given either
before or after approval of such transaction), in order that Optionees may have
a reasonable period of time prior to the closing date of such transaction within
which to exercise any Options that then are exercisable (including any Options
that may become exercisable upon the closing date of such transaction). An
Optionee may condition his exercise of any Option upon the consummation of a
transaction referred to in this Section 8(b).

         9.       ADJUSTMENT OF SHARES.

                  (a) If at any time while the Plan is in effect or unexercised
Options are outstanding, there shall be any increase or decrease in the number
of issued and outstanding Shares through the declaration of a stock dividend or
through any recapitalization resulting in a stock split-up, combination or
exchange of Shares, then and in that event:

                           (i) appropriate adjustment shall be made in the
maximum number of Shares available for grant under the Plan, or available for
grant to any person under the Plan, so that the same percentage of the Company's
issued and outstanding Shares shall continue to be subject to being so optioned;
and

                           (ii) the Board or the Committee may, in its
discretion, make any adjustments it deems appropriate in the number of Shares
and the exercise price per Share thereof then subject to any outstanding Option,
so that the same percentage of the Company's issued and outstanding Shares shall
remain subject to purchase at the same aggregate exercise price.

                  (b) Unless otherwise provided in any Option Agreement, the
Committee may change the terms of Options outstanding under this Plan, with
respect to the option price or the number of Shares subject to the Options, or
both, when, in the Committee's sole discretion, such adjustments become
appropriate so as to preserve benefits under the Plan.

                  (c) In the event of a proposed sale of all or substantially
all of the Company's assets or any reorganization, merger, consolidation or
other form of corporate transaction in which the Company does not survive, where
the securities of the successor corporation, or its parent company, are issued
to the Company's shareholders, then the successor corporation or a parent of the
successor corporation may, with the consent of the Committee or the Board,
assume each outstanding Option or substitute an equivalent option or right. If
the successor corporation, or its parent, does not cause such an assumption or
substitution to occur, or the Committee or the Board does not consent to such an
assumption or substitution, then each Option shall terminate pursuant to Section
8(b) hereof upon the consummation of sale, merger, consolidation or other
corporate transaction.

                  (d) Except as otherwise expressly provided herein, the
issuance by the Company of shares of its capital stock of any class, or
securities convertible into shares of capital stock of any class, either in
connection with a direct sale or upon the exercise of rights or warrants to
subscribe therefor, or upon conversion of shares or obligations of the Company
convertible into such shares or other securities, shall not affect, and no
adjustment by reason thereof shall be made to, the number of or exercise price
for Shares then subject to outstanding Options granted under the Plan.

                  (e) Without limiting the generality of the foregoing, the
existence of outstanding Options granted under the Plan shall not affect in any
manner the right or power of the Company to make, authorize or consummate (i)
any or all adjustments, recapitalizations,

                                       7
<PAGE>   8

reorganizations or other changes in the Company's capital structure or its
business; (ii) any merger or consolidation of the Company; (iii) any issue by
the Company of debt securities, or preferred or preference stock that would rank
above the Shares subject to outstanding Options; (iv) the dissolution or
liquidation of the Company; (v) any sale, transfer or assignment of all or any
part of the assets or business of the Company; or (vi) any other corporate act
or proceeding, whether of a similar character or otherwise.

         10. TRANSFERABILITY OF OPTIONS AND SHARES. Each Option shall provide
that such Option shall not be transferable by the Optionee otherwise than by
will or the laws of descent and distribution, and each Option shall be
exercisable during the Optionee's lifetime only by the Optionee.

         11.      ISSUANCE OF SHARES.

                  (a) Notwithstanding any other provision of this Plan, the
Company shall not be obligated to issue any Shares unless it is advised by
counsel of its selection that it may do so without violation of the applicable
Federal and State laws pertaining to the issuance of securities, and may require
any stock so issued to bear a legend, may give its transfer agent instructions,
and may take such other steps, as in its judgment are reasonably required to
prevent any such violation.

                  (b) As a condition to any sale or issuance of Shares upon
exercise of any Option, the Committee or the Board may require such agreements
or undertakings as the Committee or the Board may deem necessary or advisable to
facilitate compliance with any applicable law or regulation including, but not
limited to, the following:

                           (i) a representation and warranty by the Optionee to
the Company, at the time any Option is exercised, that he is acquiring the
Shares to be issued to him for investment and not with a view to, or for sale in
connection with, the distribution of any such Shares; and

                           (ii) a representation, warranty and/or agreement to
be bound by any legends endorsed upon the certificate(s) for the Shares that
are, in the opinion of the Committee or the Board, necessary or appropriate to
facilitate compliance with the provisions of any securities laws deemed by the
Committee or the Board to be applicable to the issuance and transfer of those
Shares.

         12.      ADMINISTRATION OF THE PLAN.

                  (a) The Plan shall be administered by the Board or, at the
discretion of the Board, by a committee appointed by the Board (the "Committee")
which shall be composed of two or more Directors. The Committee shall serve at
the pleasure of the Board and shall have

                                       8
<PAGE>   9

the powers designated herein and such other powers as the Board may from time to
time confer upon it.

                  (b) The Committee or the Board may grant Options pursuant to
this Plan to any persons to whom Options may be granted under Section 4(a)
hereof.

                  (c) The Committee or the Board, from time to time, may adopt
rules and regulations for carrying out the purposes of the Plan. The
determinations of the Committee or the Board, and its interpretation and
construction of any provision of the Plan or any Option Agreement, shall be
final and conclusive.

                  (d) Any and all decisions or determinations of the Committee
shall be made either (i) by a majority vote of the members of the Committee at a
meeting or (ii) without a meeting by the unanimous written approval of the
members of the Committee.

         13. WITHHOLDING OR DEDUCTION FOR TAXES. If at any time specified herein
for the making of any issuance or delivery of any Option or Common Stock to any
Optionee, any law or regulation of any governmental authority having
jurisdiction in the premises shall require the Company to withhold, or to make
any deduction for, any taxes or to take any other action in connection with the
issuance or delivery then to be made, the issuance or delivery shall be deferred
until the withholding or deduction shall have been provided for by the Optionee
or beneficiary, or other appropriate action shall have been taken.

         14.      INTERPRETATION.

                  (a) This Plan shall be governed by the laws of the State of
Florida.

                  (b) Headings contained in this Plan are for convenience only
and shall in no manner be construed as part of this Plan.

                  (c) Any reference to the masculine, feminine, or neuter gender
shall be a reference to such other gender as is appropriate.

         15. AMENDMENT AND DISCONTINUATION OF THE PLAN. The Committee or the
Board may from time to time amend, suspend or terminate the Plan or any Option;
provided, however, that, any amendment to the Plan shall be subject to the
approval of the Company's shareholders if such shareholder approval is required
by any federal or state law or regulation (including, without limitation, Rule
16b-3 or to comply with Section 162(m) of the Internal Revenue Code) or the
rules of any Stock exchange or automated quotation system on which the Common
Stock may then be listed or granted. Except to the extent provided in Sections 9
and 10 hereof, no amendment, suspension or termination of the Plan or any Option
issued hereunder shall substantially impair the rights or benefits of any
Optionee pursuant to any Option previously granted without the consent of the
Optionee.

         16. EFFECTIVE DATE AND TERMINATION DATE. The effective date of the Plan
is July 17, 2000, the date on which the Board adopts this Plan, and the Plan
shall terminate on the 10th anniversary of the Effective Date.

         decisions are the sole responsibility of the PPM Physicians and that
         HUMANA does not dictate or control PPM Physicians' clinical decisions
         with respect to the medical care or treatment of Members.

         itself and each of its PPM Physicians further agrees to and hereby does

         judgments, costs, liabilities, damages and expenses, including
         reasonable attorneys' fees, whatsoever, arising from any acts or
         omissions in the provision of medical services by PPM and/or PPM
         Physicians under this Agreement. This provision shall survive

         the termination.

         With the exception of Article 27, the parties have not created and do
         not intend to create by this Agreement any third party rights under

         acknowledge and agree that, with the exception of Article 27 of this
         Agreement, there are no third party beneficiaries to this Agreement.

4.       SCOPE OF THE AGREEMENT

         4.1 This Agreement sets forth the rights, responsibilities, terms and
         conditions governing: (I) PPM and PPM Physician's status as a health
         care provider contracted and credentialed by HUMANA to provide health
         care services (hereinafter "Participating Providers") to Members in
         certain health care networks established or managed by HUMANA and (II)
         PPM Physicians' services to Members. This Agreement applies only to
         those health care benefit contracts and to those Members designated by
         HUMANA.

         4.2 Upon request, HUMANA agrees to provide PPM with a listing of all
         other agreements under which PPM and PPM Physicians will be providing
         services as required by this Agreement.

         4.3 All rights and responsibilities arising in respect to Members shall
         be applicable to only the company which issued the contract covering
         the respective Members and may not be imposed or enforced upon any
         other affiliated or related

                                       2

         company. Further, with respect to self-insured contracts, unless
         otherwise indicated, HUMANA's responsibilities are limited to those of
         administration or claims processing.

         4.4 PPM represents and warrants that PPM and all PPM Physicians and
         their respective members, independent contractors and employees will
         abide by the terms and conditions of this Agreement, and PPM shall

         independent contractor and employee required to be credentialed under
         the terms of this Agreement.

         4.5 The parties agree that nothing contained in this Agreement is

         physician(s) and Members regarding patient treatment.

5.       SUBCONTRACTING PERFORMANCE

         5.1 PPM shall provide directly, or through appropriate arrangement with
         PPM Physicians and other providers of medical services, medical
         services to Members. It is understood and agreed that said PPM shall
         maintain written agreements with the PPM Physicians, and other licensed
         providers of medical care where applicable, in a form comparable to,
         and consistent with, the terms and conditions established in this
         Agreement, and in a form approved by HUMANA. A sample copy of the
         agreement between PPM and PPM Physicians in effect at the time of the
         signing of this Agreement is attached in Attachment I. In the event of
         a conflict between the language of the PPM Physician agreements and
         this Agreement, the language in this Agreement shall control. PPM
         agrees to notify HUMANA of any material change(s) to the aforementioned
         agreements at least thirty (30) days prior to implementing such
         change(s), during which period, HUMANA may object to the change(s).
         HUMANA's notice of objection shall not preclude PPM's implementation of
         such change(s), but PPM agrees that any such change(s) shall not be
         contrary to, in violation of, or inconsistent with the terms of this
         Agreement. In the event HUMANA notifies PPM of its objection, both
         parties agree to make a good faith effort to resolve such dispute n a
         timely manner.

         5.2 All PPM Physicians and other providers of medical services
         providing services to HUMANA Members shall be subject to HUMANA's
         credentialing process prior to receiving status as a HUMANA
         Participating Provider.

         5.3 PPM represents and warrants that it is authorized to negotiate
         terms and conditions of physician agreements and further to execute
         such agreements for and on behalf of PPM Physicians.

         5.4 Upon request, PPM agrees to disclose to HUMANA within a reasonable
         time period not to exceed thirty (30) days, or such lesser period of
         time required for HUMANA to comply with all applicable state and
         federal laws, rules and

                                       3
<PAGE>   4

         regulations, from such request, all of the terms and conditions of any
         payment arrangement that constitutes a physician incentive plan as
         defined by Health Care Financing Administration ("HCFA") and/or any
         state or federal law, between PPM and PPM Physicians. Such disclosure
         shall be in the form of a certification, or other form as required by
         HCFA, by PPM and shall identify, at a minimum: (I) whether services not
         furnished by the PPM Physician(s) are included; (II) the type of
         incentive plan, including the amount, identified as a percentage, of
         any withhold or bonus; (III) the amount and type of any stop-loss
         coverage provided for or required of the PPM Physicians and (IV) the
         PPM Physician(s) patient panel size, broken down by total PPM
         Physicians panel and individual PPM Physician panel size, by the type
         of insurance coverage (i.e. Commercial HMO, Medicare HMO and Medicaid
         HMO).

         5.5 PPM shall have, for the term of this Agreement, agreements with
         licensed providers of medical services that: (I) shall be in writing
         and on contract forms approved by HUMANA; and (II) shall include terms
         and conditions which comply with all applicable requirements for
         provider agreements under state and federal laws, rules and
         regulations; and (Ill) shall appoint HUMANA as the PPM's authorized
         agent for the payment of claims for Covered Services rendered to HUMANA
         Members submitted by such licensed providers and (IV) shall contain
         provisions for holding HUMANA harmless from and against any and all
         disputes between such licensed providers and HUMANA concerning the
         adjudication and the amount of the payment of the claims to the extent
         HUMANA relies on PPM's adjudication of such claims submitted for
         Covered Services rendered to HUMANA Members. In addition, from and
         after the Effective Date hereof, agreements with independent contractor
         PPM Physicians shall contain a provision to extend automatically at
         HUMANA's election the terms of such agreements to HUMANA in the event
         that this Agreement terminates for any reason for the lesser of the
         remaining term of such agreements or one (1) year.

         5.6 In the event PPM acquires, through an asset acquisition, merger,
         consolidation, lease or other means, or enters into a management
         agreement to manage the practice of physician(s) or physician groups in
         Florida, and such practices or groups have in effect an agreement with
         HUMANA to provide medical services to HUMANA Members on a capitated,
         percentage of premium or other risk sharing basis at rates which are
         more favorable to HUMANA than those contained herein, the rates
         contained herein shall be adjusted to reflect a blended rate by product
         weighted by the relative number of Members at the newly acquired or
         managed practice(s); provided, however, such blended rate shall in no
         event result in an increase in the total funding by HUMANA to PPM
         hereunder regardless of whether the newly acquired practice's
         reimbursement from HUMANA is more favorable or not.

         5.7 In the event that a PPM Physician is a party to more than one
         agreement with HUMANA for the provision of medical services to Members,
         PPM or PPM

                                       4
<PAGE>   5

         Physician will be reimbursed for Covered Services by HUMANA under the
         agreement selected by HUMANA. However, in the event that a physician
         affiliated with PPM declines participation under this Agreement prior
         to the execution of this Agreement, to the extent physician is a party
         to another agreement with HUMANA, reimbursement for the provision of
         Covered Services to Members shall be in accordance with such other
         agreement between HUMANA and the physician.

6.       LIQUIDATED DAMAGES

         PPM acknowledges and shall require PPM Physicians to acknowledge that
         HUMANA has invested and will invest substantial resources including
         funds, time, effort and goodwill in building a roll of Medicare Members
         to be treated by PPM Physicians. Therefore, PPM. agrees that PPM and
         PPM Physicians, or any of PPM or PPM Physicians' employees, principals
         or financially related entities, shall not solicit, persuade, induce,
         coerce or otherwise cause the disenrollment of any Medicare Member at
         any time, directly or indirectly. If thirty-five (35) or more Medicare
         Members assigned to an individual PPM Physician disenroll from HUMANA
         due to PPM or PPM Physicians' directly or indirectly soliciting,
         persuading, inducing, coercing or otherwise causing the disenrollment
         of such Medicare Members to be treated by PPM or any of PPM Physicians
         or PPM/PPM Physicians' employees, principals or other financially
         related entity under some other prepaid health care benefit plan other
         than HUMANA's, PPM shall pay HUMANA the amount of three thousand
         dollars ($3,000.00) for each disenrolled Medicare Member who is treated
         by PPM, or any of PPM Physicians, or PPM/PPM Physicians' employees,
         principals or any financially related entity.

         PPM hereby agrees and shall require PPM Physicians hereby to agree that
         this amount is not a penalty and constitutes liquidated damages in as
         much as the actual damages are not and cannot be ascertained at the
         time of the execution of this Agreement. PPM and PPM Physicians
         understand that this liquidated damages clause does not apply to or
         require payment from the Medicare Members under any circumstance.
         HUMANA agrees with PPM and PPM Physicians that this paragraph shall not
         be applicable in the case of any Medicare Member who disenrolls and is
         treated by a PPM Physician or anyone else on a non-prepaid and
         non-capitated fee-for-service basis as a private patient. In addition,
         Medicare Members who were patients prior to PPM Physician's
         participation as a HUMANA Participating Provider, are excluded from
         this provision, if the PPM and/or PPM Physician can furnish
         documentation to HUMANA in the form of a list of his/her patients prior
         to becoming a HUMANA Participating Provider. PPM and PPM Physicians
         have the obligation to and agree to notify HUMANA immediately of the
         name of any Medicare Member or former Medicare Member treated by a PPM
         Physician or any other person covered by this provision. This paragraph
         shall survive for twelve (12) months following the termination or
         expiration of this Agreement regardless of the cause giving rise to
         termination.

7.       POLICIES AND PROCEDURES

         7.1 PPM shall require PPM Physicians to agree to abide by all quality
         assurance, quality improvement, accreditation, risk management,
         utilization review, credentialing, recredentialing and other
         administrative policies and procedures established and revised by
         HUMANA from time to time, and such other administrative policies and
         procedures as are set out in the Affiliated Provider Manual and/or the
         Physician's Administration Manual ("Manual") and/or bulletins and
         manuals that may be promulgated by HUMANA from time to time in order to
         supplement the Manual, current copies of which hereby are acknowledged
         as received. PPM shall be notified of any revisions to the policies and
         procedures and they shall become binding upon PPM and PPM Physicians
         thirty (30) days after HUMANA has notified PPM. Additionally, HUMANA
         shall notify PPM of any other revisions to existing policies and
         procedures, at which time of notice such revisions shall become binding
         upon PPM and PPM Physicians. Any revisions affecting PPM and/or PPM
         Physicians shall not be discriminatory and shall apply to all providers
         similarly situated. PPM Physicians shall notify HUMANA's Pre-Admission
         Certification department or designated personnel of any inpatient
         admissions of HUMANA Members as required in the Manual. PPM
         acknowledges and agrees that such notification shall be prior to the
         inpatient admission(s) of any HUMANA Members not assigned to PPM
         Primary Care Physicians.

         7.2 PPM further agrees, in accordance with the Letter of Agreement to
         be signed by each PPM Physician, an example of which appears in
         Attachment H, that PPM and HUMANA may share information, including but
         not limited to credentialing, recredentialing, quality management and
         utilization management information as related to the treatment of
         Members. However, it expressly is understood that the information shall
         not be shared with anyone other than HUMANA and PPM, unless required by
         law or pursuant to prior written consent of the PPM Physician involved.

         7.3 PPM acknowledges and agrees that a signed Letter of Agreement, (in
         a form substantially similar to that form attached hereto as Attachment
         H), for each PPM Physician participating under this Agreement shall be
         provided to HUMANA prior to execution of this Agreement, and prior to
         the provision of services to HUMANA Members for those PPM Physicians
         who join PPM and are approved by HUMANA and agree to participate under
         this Agreement and/or whose credentialing applications are approved
         subsequent to execution of this Agreement. Notwithstanding the above,
         PPM acknowledges and agrees that PPM shall sign the Letter of Agreement
         on behalf of those PPM Physicians that are employed by PPM, and all
         other PPM Physicians shall sign a Letter of Agreement on an individual
         basis. PPM Physicians who do not execute such Letter of Agreement shall
         not be entitled to participate under this Agreement and will not be
         listed in HUMANA's provider directories.

                                       6

         7.4 All administrative services, including but not limited to
         credentialing, recredentialing, utilization management, quality
         assurance and fiscal services, shall be performed by HUMANA. However,
         HUMANA in its sole discretion wilt discuss with PPM, PPM's provision of
         such services at such time as PPM may demonstrate administrative or
         information service capabilities acceptable to HUMANA.

8.       CREDENTIALING

         8.1 All PPM Physicians who will provide medical services to Members
         hereunder are required to be credentialed, and shall be subject to the
         credentialing process prior to receiving status as a HUMANA
         Participating Provider.

         8.2 Participation under this Agreement by PPM, and each of its PPM
         Physicians, is subject to the satisfaction and maintenance, in HUMANA's
         sole judgement, of all credentialing and recredentialing standards
         established by HUMANA's credentialing and/or medical affairs
         departments and adopted under the policies and procedures set out in
         the Manual and other rules and regulations promulgated thereby. PPM
         and/or PPM Physicians shall provide HUMANA with the information
         necessary to ensure compliance with this Article 8 at no additional
         expense to HUMANA and/or any vendor to whom HUMANA at its sole
         discretion, may delegate the credentialing and/or recredentialing
         process(es) to.

         8.3 HUMANA reserves the right to approve new PPM Physicians and/or, as
         applicable, other health care providers required to be credentialed, or
         to terminate or suspend any PPM Physician or, other health care
         providers required to be credentialed, who will be or is providing care
         to HUMANA Members, who does not meet or fails to maintain HUMANA's
         credentialing and/or recredentialing standards. HUMANA agrees to notify
         PPM of its decision to terminate any PPM Physician or any other PPM
         health care provider required to be credentialed under HUMANA standards
         and, except in cases of immediate terminations, PPM shall have fourteen
         (14) days from such notice to request reconsideration of such decision
         by HUMANA's Medical Director. However, PPM acknowledges and agrees that
         HUMANA shall have the final decision on the matter. PPM further
         acknowledges and agrees and shall require PPM Physicians further to
         acknowledge and agree that any limitation and/or suspension and/or
         termination of his/her credentialing or recredentialing status by
         HUMANA or any one or more of HUMANA's affiliates shall apply uniformly
         to PPM Physician(s)' credentialing or recredentialing status with
         HUMANA and all of its affiliates. In the event the limitation,
         suspension and/or termination is for administrative reasons, HUMANA or
         any of its affiliates may elect to reject the administrative action of
         the acting HUMANA entity's determination.

         PPM Physicians required to be so licensed or certified, to procure and
         maintain for the term of this Agreement such licensure and/or
         certification as is required under HUMANA's policies and procedures,
         under the terms and conditions of this Agreement, in compliance with
         the provisions in the Manual, and in accordance with all applicable
         state and federal laws. PPM shall and/or shall require PPM Physicians
         to notify HUMANA immediately of any changes in licensure or

         applicable.

         9.2 PPM represents and warrants that it has obtained and shall maintain
         any and all licenses, certificates and/or approvals required under
         Florida and/or federal laws, rules and regulations, for the performance
         by PPM of its duties and obligations under this Agreement. Further, PPM
         shall maintain a valid Florida Third Party Administrator's License
         during the term of this Agreement, where PPM is required to do so.

10.      MEDICAL SERVICES TO BE PROVIDED

         10.1 PPM on behalf of itself and PPM Physicians, desires to become a
         Participating Provider under the terms of this Agreement and agrees to
         provide and/or arrange for health care services for Members, in
         accordance with this Agreement and the applicable Member health
         benefits contract (hereinafter "Covered Services"). PPM Physicians'
         responsibilities for providing and/or arranging Covered Services to

         HUMANA's approval, which shall not unreasonably be withheld. Failure to
         obtain HUMANA's prior approval may result, at HUMANA's sole and
         complete discretion, in the termination of such PPM Physician(s) and/or
         office sites from participation under this Agreement.

         10.2 In the event PPM and/or PPM Physician(s) dispute what services are
         covered under the applicable health care benefits plan contract, the
         Medical Directors of HUMANA and PPM shall make reasonable efforts to
         resolve such disputes. However, PPM agrees that HUMANA shall have sole
         and final authority to interpret and determine what services and/or
         benefits are covered under the applicable health care benefits
         contract.

         These services shall be made available to Members without
         discrimination on the basis of health care benefit plan, source of
         payment, sex, age, race, color, religion, national origin, health
         status or other handicap, and in the same manner as provided to PPM
         Physicians' other patients. PPM agrees to require that PPM Physicians
         provide medical services to Members in accordance with the prevailing
         practices and standards of the profession.

         11.2 PPM understands and agrees and shall require PPM Physicians to
         agree that HUMANA may deny payment(s) for medical services rendered to
         Members which are, in the opinion of HUMANA, determined not to be
         medically necessary. "Medically Necessary" (or "Medical Necessity")
         shall mean services or supplies provided by a hospital, physician or
         other health care provider, licensed by the appropriate state agency,
         or as otherwise approved as required, to diagnose or treat a condition,
         disease, ailment, sickness or bodily, injury and which, in the opinion
         of HUMANA, are: (I) consistent with the symptoms. Diagnosis and
         treatment of such condition, disease, ailment, sickness or bodily
         injury; (II) appropriate with regard to standards of accepted medical
         practice; (III) not primarily for the convenience of the patient or the
         qualified hospital, physician or other health care provider; (IV) the
         most appropriate and cost-effective supply, setting, or level of
         service which safely can be provided to the patient and (V)
         substantiated by the records and documentation maintained by the
         provider of services. When applied to an inpatient, it further means
         that the patient's symptoms or condition requires that the services or
         supplies cannot safely be provided to the patient as an outpatient. Any
         disputes regarding Medical Necessity shall be handled in accordance
         with Section 10.2 of this Agreement.

         11.3 HUMANA may authorize payment for Medically Necessary Covered
         Services for Members based on HUMANA's discretion and in accordance
         with the applicable Member health care benefits contract. Such services
         shall be paid for as if authorized by PPM and/or PPM Physicians and in
         accordance with the applicable payment arrangements outlined herein. In
         the event HUMANA so authorizes payment for Medically Necessary Covered
         Services, HUMANA agrees to notify PPM concurrently of such
         authorization.

12.      USE OF PARTICIPATING PROVIDERS

         12.1 Except in the case of a medical emergency, PPM shall require PPM
         Physicians to admit, refer and cooperate with the transfer of Members
         for Covered Services only to providers designated, specifically
         approved or under contract with HUMANA.

         12.2 In the event that a PPM Physician provides a Member non-covered
         services or refers a Member to an out-of-network provider without
         pre-authorization from HUMANA, PPM shall require PPM Physicians prior
         to the provision of such non-covered services or such out-of-network
         referral, to inform

                                       9
<PAGE>   10

         the Member: (I) of the services to be provided or referral to be made;
         (II) that HUMANA will not pay (or may pay a reduced benefit in the case
         of HUMANA's point of service (POS) and/or preferred provider
         organization (PPO) products) or be liable financially for such
         non-covered service or out-of-network referral and (III) that Member
         will be responsible financially for non-covered service(s) and/or
         out-of-network(s) referral that are requested by the Member. PPM
         acknowledges and agrees and shall require PPM Physicians to acknowledge
         and agree that the failure to inform Member(s) in accordance with this
         Section 12.2 may result in the PPM's and/or PPM Physician's
         responsibility and financial liability for the cost of such non-covered
         service(s) and/or out-of-network referral incurred by HUMANA.

13.      EQUAL ACCESS

         PPM agrees and shall require PPM Physician(s) to agree to accept HUMANA
         Members as patients within the normal scope of PPM Physicians' medical
         practices. If for any reason, PPM Physician(s), individually and/or
         collectively, close their practice(s), such closure will apply to all
         prospective patients without discrimination or regard to payor or
         source of payment for services, Should PPM Physician(s) subsequently
         re-open their practices to new patients, PPM agrees and shall require
         PPM Physician(s) to agree to accept HUMANA Members as patients are
         accepted to the same extent non-HUMANA patients seeking PPM
         Physician(s)' services. Notwithstanding the above, any such closure of
         an PPM Physician(s)' practice to new patients is subject to the
         limitation outlined in Section 10.1 and Attachment D of this Agreement.

14.      PPM PHYSICIAN FACILITIES

         PPM Physicians will establish and maintain regular business hours for
         the provision of services to HUMANA Members. In establishing business
         hours, PPM and PPM Physicians shall take into consideration the number
         and type of Members assigned to and/or receiving services at the office
         site. The business hours established by PPM and PPM Physicians are
         noted in Attachment C of this Agreement. This does not relieve PPM
         Physicians of their obligation to provide medical coverage for Members
         twenty-four (24) hours a day, seven (7) days a week.

15.      SOFTWARE USE

         PPM and/or PPM Physicians may use certain software as may be identified
         by HUMANA that is licensed to HUMANA and/or its subsidiaries, parent
         and/or affiliates. Such use is conditioned upon PPM and PPM Physicians'
         strict compliance with the HUMANA Security Guidelines, and upon use
         solely as indicated by HUMANA, and treatment of the software as
         confidential property of HUMANA's licensor and not subject to
         disclosure to third parties without the prior written consent of
         HUMANA. Such prohibition on disclosure shall not

                                       10
<PAGE>   11

         apply to disclosures to PPM's and/or PPM Physicians' employees provided
         the disclosure reasonably is necessary to use the software, and
         provided PPM, and PPM Physicians take all reasonable steps to ensure
         the software is not duplicated or disclosed to third parties. If PPM
         and/or PPM Physicians become aware of an unauthorized use, duplication
         or disclosure, PPM and/or PPM Physicians shall provide full details to
         HUMANA promptly and take all reasonable steps to prevent any such
         recurrence. Upon request by HUMANA, PPM and/or PPM Physicians shall
         return to HUMANA all copies of the software, purge all machine readable
         media relating to such software and certify to HUMANA that the
         foregoing duties have been performed. These obligations of
         confidentiality, non-disclosure, non-reproduction and return of
         material shall survive any termination or expiration of this Agreement.

         16.1 At all times, PPM will maintain and will require each PPM
         Physician to maintain, at no expense to HUMANA, such policies of
         comprehensive general liability, professional liability and workers'
         compensation coverage, with such carriers and in such amounts as HUMANA
         reasonably may approve, insuring PPM and each PPM Physician, their
         officers, directors, members, employees, agents and subcontractors (as
         applicable), against any claim or claims for damages arising as a
         result of injury to property or person including death, occasioned
         directly or indirectly, in connection with the performance of medical
         services contemplated by this Agreement and/or the maintenance of PPM
         and/or PPM Physicians' facilities and equipment. Prior to execution of
         this Agreement, and at any time subsequently upon request, PPM and PPM
         Physicians shall provide HUMANA with evidence of said coverage, of
         which minimum professional liability coverage for PPM shall be five
         million dollars ($5,000,000.00) and for each PPM Physician shall be one
         million dollars ($1,000,000.00) per occurrence/three million dollars
         ($3,000,000.00) in the aggregate, or such amount as required by state
         law, whichever is greater number. PPM shall provide and/or shall
         require PPM Physicians to provide, or shall require the carrier(s) to
         provide, HUMANA with ten (10) days prior written notice of any
         suspensions, cancellations of, or modifications in the coverage. This
         clause shall survive the expiration and/or termination of this
         Agreement, regardless of the cause, for a period of time not less than
         the applicable Statute of Limitations in this State.

         16.2 PPM agrees to cooperate with HUMANA in assuring that any stop-loss
         coverage required by law is made available. PPM agrees and shall
         require PPM Physicians to agree that compensation received from HUMANA
         shall be adjusted by the cost of any stop-loss coverage which HUMANA
         may be required by law to provide.

         At all times, HUMANA will maintain such policies of comprehensive
         general liability insurance and other insurance or self insurance, as
         shall be necessary to insure HUMANA against any claim or claims for
         damages arising in connection with the performance of HUMANA's
         responsibilities under this Agreement. If requested by PPM, HUMANA
         shall provide PPM evidence of such coverage upon execution of this
         Agreement and thereafter at reasonable intervals as requested by PPM
         during the term of this Agreement. This clause shall survive for a
         period of time not less than the applicable Statute of Limitations in
         this state.

         18.1 PPM shall require PPM Physicians to prepare, maintain and retain
         records relating to Members in such form and for such time periods as
         required by applicable state and federal laws, licensing, accreditation
         and reimbursement rules and regulations to which HUMANA is subject, and
         in accordance with accepted medical practice and HUMANA standards
         HUMANA, pursuant to authorization of the Member signed at time of
         enrollment during the application process, the sufficiency of which
         hereby is acknowledged, or any federal or state regulatory agency, as
         permitted by law, may obtain, copy and have access, upon reasonable
         request, to any medical, administrative or financial record of PPM
         and/or PPM Physicians related to Covered Services provided by PPM
         Physicians to any HUMANA Member. Copies of such records shall be at no
         additional cost to HUMANA or the Member.

         18.2 Upon request from Humana or a Member, PPM agrees and shall require
         PPM Physicians to agree to transfer the complete original or a complete
         acceptable copy of the medical records of any Member to another
         physician or provider for any reason, including termination of this
         Agreement. The transfer of medical records shall be at no cost to
         either HUMANA or the Member and shall be made within a reasonable time
         following the request but in no event less than five (5) business days
         except in cases of emergency. PPM agrees and shall require PPM
         Physicians to agree that such timely transfer of medical records is
         necessary to ensure the continuity of care for Members. PPM agrees to
         pay court costs and/or legal fees necessary for HUMANA to enforce the
         terms of this provision.

         may result in legal action.

20.      GRIEVANCE AND APPEALS PROCESS

         PPM agrees and shall require PPM Physicians to agree to cooperate and
         participate with HUMANA in its grievance and appeals processes to
         resolve disputes which may arise between HUMANA and PPM/PPM Physicians
         and/or HUMANA and it Members. PPM shall comply and shall require PPM

         21.3 PPM agrees and shall require PPM Physicians to agree to: (I) allow

         payments owed by Members pursuant to their health benefits contract,
         including but not limited to copayments, deductibles, coinsurance
         and/or cost-share amounts (hereinafter referred to as "Copayments")
         required directly from the Member, and shall not waive, discount or

         due from Members, shall be accepted by PPM and at PPM's direction by
         PPM Physicians as payment in full for all Covered Services.

         22.2 HUMANA shall have the right to conduct, or have conducted by a
         third party, audits and evaluations from time to time of all billing
         and financial records of PPM and/or PPM Physicians related to medical

         designee access to PPM's billing and financial records and those of PPM
         Physicians to conduct the audits and evaluations.

         22.3 Notwithstanding anything to the contrary identified herein, PPM or
         PPM Physicians, as applicable, have the right to dispute reimbursement

         HUMANA will review such contestation(s) and respond to PPM within sixty
         (60) days of the date of receipt by HUMANA of such contestation. The
         parties acknowledge and agree that HUMANA's decision on the matter will
         be final. Failure to contest the amount of any claim paid hereunder

         Physicians receive services and/or treatment at another facility or
         from another physician or health care provider, payment for such
         services and/or treatment shall be in accordance with the contracted
         rates with such other facility, physician or other health care
         provider, to the extent such a contract exists between HUMANA and such

<PAGE>   15

         22.5 Further, PPM acknowledges and agrees and shall require PPM
         Physicians to acknowledge and agree that HUMANA may deny payment of
         medical services rendered to Members, which are determined not to be
         Medically Necessary by HUMANA. PPM agrees and shall require PPM
         Physicians to agree that in the event of a denial of payment for
         services rendered to Members that are determined not to be Medically
         Necessary, PPM shall not and shall require PPM Physicians to agree not
         to bill, charge, seek payment or have any recourse against Members or
         persons other than HUMANA acting on their behalf for medical services
         provided pursuant to this Agreement.

23.      BILLING/ENCOUNTER PROCEDURES

         23.1 PPM shall and/or shall require PPM Physicians to prepare and
         submit to HUMANA, according to billing procedures established by
         HUMANA, billing and/or encounter information for Members who have
         received Covered Services. PPM shall require PPM Physicians to use the
         standard billing and encounter forms required or agreed to by HUMANA.

         23.2 PPM shall require PPM Physicians and PPM affiliated health care
         providers to submit all claims and encounters to HUMANA electronically
         by means available and accepted as industry standards that are mutually
         agreeable, which may include claims clearinghouses, or IMS-Medacom, or
         other technology that is mutually agreed upon by HUMANA and PPM, and in
         accordance with published HUMANA claims policies, procedures and
         guidelines on the earlier of the Effective Date of this Agreement or
         six (6) months following execution of this Agreement. Should PPM and/or
         PPM Physicians be unable to submit claims electronically upon execution
         of this Agreement, PPM and/or PPM Physicians shall make such
         arrangements as may be necessary, at their sole expense, to do so
         within six (6) months from the date of execution of this Agreement. For
         purposes of this Agreement, "claims" shall be defined as notification
         to an insurance or managed health care company that payment of an
         amount is due under the terms of this Agreement and in accordance with
         the applicable Member health benefits contract.

         23.3 Should PPM and/or PPM Physicians fail to comply with the terms of
         Section 23.2 above, HUMANA may, at its sole discretion pend payment of
         monies to PPM and/or PPM Physicians until completed claims are
         submitted electronically. In no event will HUMANA's Members be
         responsible for monies in addition to those Copayments due under the
         applicable Member health care benefits contract.

         23.4 PPM agrees and shall require PPM Physicians to agree to submit all
         fee-for-service claims eligible for reimbursement as provided under
         this Agreement within sixty (60) days from the date of service. HUMANA
         may, at its sole discretion, deny payment for any such fee-for-service
         claim(s) received after sixty

                                       15
<PAGE>   16

         (60) days from the date of service. PPM acknowledges and agrees and
         shall require PPM Physicians to acknowledge and agree that at no time
         shall HUMANA's Members be responsible for any payments in addition to
         applicable Copayments for Covered Services provided to such Members. In
         the event the penalty described herein is effected, the Member's
         Copayment, if any, shall be adjusted accordingly.

         23.5 In the event that PPM or PPM Physician(s), as applicable, are
         reimbursed for Covered Services on a capitated basis, and no claims for
         services are submitted to HUMANA at the time of service, PPM agrees and
         shall require PPM Physicians to agree to provide HUMANA accurate and
         complete information ("Encounter Data") regarding the provision of
         Covered Services for Members in a form mutually to be agreed upon by
         both parties. Encounter Data shall include at a minimum Member
         identification and demographic information, PPM and/or PPM Physician
         tax identification number, date of service, all applicable CPT-4 and
         ICD-9 codes, and where applicable billed charges.

         23.6 PPM acknowledges and agrees, and shall require PPM Physicians to
         acknowledge and agree, that such Encounter Data shall be provided to
         HUMANA on a monthly basis on or before the last day of each month for
         encounters occurring in the immediately preceding month. In the event
         PPM and/or PPM Physicians fail to provide, or arrange for the provision
         of, the Encounter Data by the date specified above, and upon HUMANA's
         notice to PPM of such failure, PPM shall have thirty (30) days from the
         date of said notice to develop a corrective action plan acceptable to
         HUMANA to insure compliance with the timely submission of the Encounter
         Data. In the event the corrective action plan is unacceptable to
         HUMANA, or the plan fails to correct the problem within sixty (60) days
         of implementation of the corrective action plan, HUMANA, at its sole
         discretion, may: (I) withhold PPM's and/or PPM Physicians', as
         applicable, subsequent payments or (II) pend such payments until such
         Encounter Data is submitted to HUMANA in an acceptable form, or (III)
         terminate this Agreement upon at least sixty (60) days written notice
