         any item of realized or unrealized gain/loss which such Third Party
         Accountant shall determine in writing shall be binding and conclusive
         on the parties and shall be so reflected in a final Valuation Report.

         accountants involved in this valuation process.

                                       8

         and such loss is less than the Initial Net Loss, or if it is a gain,
         Seller shall be entitled to, and Purchaser shall pay promptly, and in
         any event within ten (10) Business Days following issuance of a final
         Valuation Report, to Seller, an amount equal to the difference between

         Gain or Loss as determined in Section 2.02(b)(ii) is a loss and such
         loss is greater than the Initial Net Loss, Purchaser shall be entitled
         to, and Seller shall pay promptly, and in any event within ten (10)
         Business Days following issuance of a final Valuation Report, to
         Purchaser, an amount equal to the difference between the Final Net Gain

         made together with interest on the amount of such difference for the
         period from the Closing Date until the date of payment at an effective
         annual rate equal to the annual interest rate for 90-day United States
         Treasury Bills prevailing on the Closing Date plus 50 basis points. The
         payment made pursuant hereto shall be made by bank wire transfer of

                  (xv) any incurrence by the Company of any material liability
         for rate roll-backs or premium refunds, or failure by the Company to
         pay in full all guaranty fund assessments of which written notice has
         been received from any Governmental Authority; or

                  (xvi) any authorization, approval, agreement or commitment to
         do any of the foregoing.

                  SECTION 4.10. INSURANCE RESERVES. The Reserves as of the
Reference Date and any subsequent date on which such Reserves may have been
redetermined (i) were determined in accordance with SAP; (ii) were computed in
accordance with generally accepted loss reserving standards and principles;
(iii) met the requirements of the Florida Insurance Department; and (iv) made
reasonable provision, in the aggregate, for all unpaid loss and loss expense
obligations, including obligations for incurred but not reported loss and loss
adjustment expenses, and unearned premiums as of the Reference Date. Except as
set forth in Section 4.10 of the Disclosure Schedule, none of the Reserves
reflected on the Quarterly Statutory Statement dated as of the Reference Date
have been discounted in any manner. The Company owns assets that qualify as
"admitted assets" under the Florida Insurance Code in an amount at least equal
to the Reserves plus its minimum statutory capital and surplus as required under
the Florida Insurance Code. Seller has delivered or made available to Purchaser
true and complete copies of all actuarial reports, actuarial certificates and
loss and loss adjustment expense reserve reports prepared internally or by any
third party actuarial consultant on behalf of or made available to Seller or any
of its Affiliates, including the Company, in each case relating to the adequacy
of the Reserves for any period ended on or after December 31, 1996. The
foregoing notwithstanding, Seller makes no representation and gives no warranty
with respect to the adequacy of the Reserves to cover the actual amount of
losses and loss adjustment expenses paid after the date hereof.

                  SECTION 4.11. JUDGMENTS, DECREES AND ORDERS. Except as set
forth in Section 4.11 of the Disclosure Schedule, neither the Company nor any of
its directors, officers or employees (in their capacity as such) is a party to
or subject to any judgment, decree, order, writ, award, or injunction of any
Governmental Authority or arbitrator. The Company is in compliance in all
material respects with respect to all judgments, orders, writs, arbitration
awards, injunctions, decrees or awards of any Governmental Authority or
arbitrator to which it is subject.

                  SECTION 4.12. LITIGATION. Except as set forth in Section 4.12
of the Disclosure Schedule, there are no claims, actions, suits, investigations,
arbitrations or legal, administrative

                                      19

<PAGE>


or other proceedings pending and, to the Knowledge of Seller, none are
threatened, against or affecting the Company or any of its Properties, at law or
in equity, or before or by any Governmental Authority or arbitrator. Except as
set forth in Section 4.12 of the Disclosure Schedule, since September 8, 1997,
except with respect to payments made in the ordinary course in connection with
Reinsurance Agreements or Insurance Policies written by the Company, there have
been no payments made by or on behalf of the Company (other than pursuant to an
Insurance Policy or Reinsurance Agreements) with respect to any threatened or
previously outstanding litigation.

                  SECTION 4.13. COMPLIANCE WITH LAWS. The Company is in
compliance with (a) the terms of its certificate or articles of incorporation,
its by-laws and any other charter or organization documents, (b) all laws,
statutes, ordinances, rules, regulations or other legal requirements, whether
federal, state, local or foreign, applicable to the Company or by which any of
its Properties may be bound, (c) except as set forth in Section 4.13 of the
Disclosure Schedule, all applicable licenses, authorizations, orders, writs,
judgments, injunctions, awards, and decrees of any court, the Florida Insurance
Department or any other Governmental Authority, or any arbitrators, and (d) its
Permits, except, in the case of clauses (b), (c) and (d), where the failure to
comply would not, individually or in the aggregate, have a Material Adverse
Effect.

                  SECTION 4.14. ENVIRONMENTAL, HEALTH AND SAFETY COMPLIANCE.
Except as set forth in Section 4.14 of the Disclosure Schedule, the Company is
not engaged in, and has not been engaged in, the creation, generation or
disposal, on- or off-site, of Hazardous Substances.

                  SECTION 4.15. LICENSES AND PERMITS. Except as set forth in
Section 4.15 of the Disclosure Schedule, the Company has all governmental
licenses, permits and authorizations (other than those relating to the writing
of insurance which are covered by the next sentence) necessary to carry on the
Business now being conducted by the Company (collectively, the "PERMITS"), all
of which are valid and in full force and effect, except for such Permits the
absence of which, individually or in the aggregate, would not have a Material
Adverse Effect. Section 4.01 of the Disclosure Schedule lists all jurisdictions
in which the Company is licensed, authorized or permitted to write insurance or
reinsurance. Except as set forth in Section 4.15 of the Disclosure Schedule,
since September 8, 1997, and, prior to such date to the Knowledge of Seller, the
Company has been duly authorized by the relevant state, foreign and other
insurance regulatory authorities to write the lines of insurance or reinsurance
that it has written in the respective jurisdictions in which it has done
business. No insurance regulator in any state has notified the Company, orally
or in writing, that the Company is commercially domiciled in any jurisdiction,
and neither Seller nor the Company is aware of any facts that would result in
the Company being commercially domiciled in any state. The insurance licenses
attached to Section 4.01 of the Disclosure Schedule are the licenses necessary
for the Company to conduct the Business in the manner and in the areas in which
such Business is currently being conducted except where the failure to be so
licensed would not, individually or in the aggregate, have a Material Adverse
Effect, and all of the insurance licenses are valid and in full force and
effect. The Company has not received any notice, oral or written, that it has,
and it has not, engaged in

                                       20

<PAGE>


any activity which would cause modification, limitation, non-renewal, revocation
or suspension of any insurance license or Permit, and no action, inquiry,
investigation or proceeding looking to or contemplating the revocation,
modification, limitation, non-renewal or suspension of any thereof is pending or
threatened. Except as set forth in Section 4.15 of the Disclosure Schedule, (i)
all reports, statements, documents, registrations, filings and submissions to
state insurance regulatory authorities complied in all material respects with
applicable law in effect when filed and (ii) no deficiencies have been asserted
by any such regulatory authority with respect to such reports, statements,
documents, registrations, filings or submissions that have not been satisfied in
all material respects.

                  SECTION 4.16. INTELLECTUAL PROPERTY RIGHTS. Section 4.16 of
the Disclosure Schedule sets forth a list of each trade name, service mark,
trademark, logo, copyright, patent and other intangible property used by the
Company or in the Business which is material to the conduct of the Business,
other than computer software which will be provided by Humana Workers
Compensation Services, Inc., a Florida corporation ("HWCS"), as further provided
in Section 4.28 of this Agreement (collectively, "INTELLECTUAL PROPERTY
RIGHTS"), which are all the material Intellectual Property Rights that are
required to conduct the Business. Except as set forth in Section 4.16 of the
Disclosure Schedule, the Company owns and has good title or has valid and
enforceable licenses relating to all of the Intellectual Property Rights, and
has the right to use the Intellectual Property Rights, free and clear of any
royalty or other payment obligation (except as provided in any license) or, to
the Knowledge of Seller, claims of infringement or other Encumbrance. Neither
Seller nor the Company has received any notice, in writing, of any conflict with
or violation or infringement of, any rights of any other Person with respect to
any Intellectual Property Right. The Intellectual Property Rights have been
registered to the extent required with the appropriate Governmental Authority
and such registrations have been continuously maintained and are in full force
and effect, except where the failure to register or to maintain any such
registration would not, individually or in the aggregate, have a Material
Adverse Effect. To the Knowledge of Seller, the rights of the Company to the
Intellectual Property Rights are not being infringed by others. No licenses have
been granted by the Company, and, to the Knowledge of Seller, there is no
obligation requiring the Company to grant any license, with respect to any of
the Intellectual Property Rights.

                  SECTION 4.17.  PROPERTY.

                  (a) The Company neither owns nor leases any real or tangible
personal property.

                  (b) Except as set forth in Section 4.17(b) of the Disclosure
Schedule, the Company has good title to, or a valid license in, all its
intangible personal Property free and clear of all Encumbrances, except (i)
liens for Taxes and assessments not yet payable; (ii) liens, imperfections of
title and easements which do not, either individually or in the aggregate,
materially detract from the value of, or interfere with the present use of, the
Properties subject thereto or affected thereby (the exceptions in clauses (i)
and (ii) being herein called "PERMITTED

                                       21

ENCUMBRANCES").

operating condition and repair, reasonable wear and tear excepted, and (ii)
adequate for the Business currently conducted by the Company and suitable in all
respects for the purposes for which they are now being used, except for such
failures to be in such good operating condition or adequacy or suitability
which, individually and in the aggregate, do not have a Material Adverse Effect.

                  SECTION 4.18. COMPANY'S PROPERTY & CASUALTY INSURANCE
COVERAGE.

                  (a) Section 4.18 of the Disclosure Schedule contains a true

directors and officers liability, surety bonds, key-man and life insurance and
other similar Insurance Policies (including the expiration dates thereof, the

insure the business, operations or affairs of the Company that (i) have been
issued to the Company or (ii) are held by Seller or by any Affiliate of Seller
for the benefit of the Company and that will not continue to be applicable to
the Company following the Closing. All such insurance is in full force and
effect and, to the Knowledge of Seller and the Company, is with financially
sound and reputable insurers in accordance with normal industry practice.

                  (b) Since January 1, 1998, the Company has not failed to give
any material notice or to present any material claim under any Insurance Policy
or surety bond in due and timely fashion. Seller has given Purchaser the most
recently available reports for the Company on: (i) accidents, casualties or
damages occurring on or to the Properties or assets of the Company; and (ii)

indemnification under any Insurance Policy and settlements or negotiations of

<PAGE>


                  (a) As used in this Agreement, the term "REINSURANCE
AGREEMENTS" shall mean all assumed and ceded reinsurance and retrocession
agreements, contracts, treaties, obligations, instruments or other reinsurance
or retrocession commitments, arrangements or undertakings of any kind to which
the Company is a party or by which the Company or any of its respective
Properties may be bound or affected and shall further include, without
limitation, any portfolio reinsurance or other assumption transaction where the

limit). Except as set forth in Section 4.20(c) of the Disclosure Schedule, (i)
to the Knowledge of Seller, none of such retrocessionaires is insolvent or the

bankruptcy or similar proceeding; (ii) to the Knowledge of Seller, the financial
condition of any such retrocessionaire is not impaired to the extent that a
default thereunder is reasonably anticipated, (iii) no notice of intended

the Company and are properly reflected in the Annual Statutory Statements.
Seller will deliver to Purchaser at the Closing a complete and accurate list of
each Retrocession Arrangement in force five Business Days prior to the Closing
Date including information similar to Section 4.20(c) of the Disclosure
Schedule. Except as set forth in Section 4.20(c) of the Disclosure Schedules, no

                  (d) All of the Reinsurance Agreements are valid, binding and
enforceable against the Company and, to the knowledge of Seller, against the
other parties thereto in

                                       23

the Knowledge of Seller, no other party thereto is, in or claimed to be in
material breach or material default under any Reinsurance Agreement, and no
event has occurred which (after notice or lapse of time or both) would become a
material breach or material default under, or would permit modification,
cancellation, acceleration or termination of, any Reinsurance Agreement or
result in the creation of any material Encumbrance upon, or result in any Person
obtaining any right to acquire, any Properties or rights of the Company. There
are no unresolved disputes under any Reinsurance Agreement.

Subject to Section 10.04(c), any future refunds for assessments previously paid
by the Company to the Florida Special Disability Trust Fund shall be the sole
property of the Company.

                  (xxii) take any action or course of action inconsistent with
         its compliance with the covenants and agreements contained in this
         Agreement;

                  (xxiii) take or agree to commit to take any action that would

the Company's officers, directors, employees, auditors and agents to, (i) afford
the officers, employees and authorized agents and representatives of Purchaser
reasonable access, during normal business hours and upon reasonable advance
notice, to the offices, properties, books and records of the Company and to
Seller's, its Affiliates and the Company's respective officers, employees,
agents, accountants and actuaries in order to make such investigation of the
Company and its Business, Properties and operations as it deems necessary, and
(ii) furnish to the officers, employees and authorized agents and
representatives of Purchaser such additional financial and operating data and
other information regarding the assets, Properties, goodwill and Business of the

burden or expense as Purchaser may from time to time reasonably request.
Purchaser agrees that said investigation shall be conducted in such a manner as
not to interfere unreasonably with the operation of the Company, Seller or its

records are relevant to the inquiry, and such access shall be limited to such
relevant books and records.

                  (b) If, in order properly to prepare documents required to be
filed with Governmental Authorities or their financial statements, it is
necessary that any party hereto or any successors be furnished with additional
information relating to the Company or the Business, and such information is in
the possession of the other party hereto, such party agrees to use all
reasonable efforts to furnish such information to such other party, at the cost
and expense of the party being furnished such information upon the furnishing by
the requesting party the reason such information is necessary, and excluding
from Purchaser's and from Seller's obligations any information which is subject
to a confidentiality agreement with any third Person and which cannot be given
after reasonable efforts (including the giving of such commitments as to
confidentiality the requesting party may need to give) have been used by the
party which is subject to the confidentiality agreement to secure the consent of
such third Person to the use or disclosure of such information.

                  SECTION 6.04. REGULATORY AND OTHER AUTHORIZATIONS; CONSENTS.

                  (a) Each party hereto will use all reasonable efforts to
obtain all authorizations, consents, orders and approvals of all Governmental
Authorities that may be or become necessary for its execution and delivery of,
and the performance of its obligations pursuant to, this Agreement and, as to
Purchaser, it shall use its reasonable best efforts to obtain such consents and
approvals from the Florida Insurance Department and the New York Insurance
Department as may be necessary for it to reinsure all or a portion of the
Company's Business with one or more Affiliates of Purchaser (including, without
limitation, any required approvals of the Florida Insurance Department and New
York Insurance Department), and will cooperate fully with the other parties in
promptly seeking to obtain all such authorizations, consents, orders and
approvals. Each party hereto agrees to make an appropriate filing of a
Notification and Report Form pursuant to the HSR Act with respect to the
transactions contemplated hereby as soon as reasonably practicable after the
date hereof and to supply promptly any additional information and documentary
material that may be requested pursuant to the HSR Act. Purchaser agrees to make
its initial filing pursuant to Florida Insurance Code Section 628.461 (the "FORM
A FILING") and pursuant to New York Insurance Law Section 1603 (the "NY FILING")
within fifteen (15) Business Days of the date hereof, and to promptly commence
all necessary actions to obtain an order from the Florida Insurance Department
(y) approving the Amended and Restated Management Agreement and (z) discharging
or modifying the Consent Orders of the Florida Insurance Department dated
September 8, 1997 and December 23, 1999 (collectively, the "CONSENT ORDERS") to
permit the transactions contemplated herein, to fully and unconditionally
release and discharge the Company, Seller, Humana and any of their Affiliates
from all obligations and liabilities under such Consent Order and any other
orders in respect of the Company. Purchaser further agrees to supply promptly
any additional information and documentary material that may be requested by the
Florida or New York Insurance Departments in connection with such filing and
proceedings. Purchaser agrees to provide draft of the Form A Filing and NY
Filings to Seller for its review and to consult with Seller relating to any
issues arising as a result of Seller's review, prior to the submission by
Purchaser of the Form A Filing

                                       39

<PAGE>


to the Florida Insurance Department and the NY Filing to the New York Insurance
Department; provided that such consultation does not delay the timely filing of
either the Form A Filing, the NY Filing or any amendments or supplements thereto
and it being agreed that the final determination as to the content of such
filings or any amendments or supplements thereto shall remain with Purchaser.
Purchaser agrees to provide Seller with copies of the Form A Filing and the NY
Filing and each amendment or supplement thereto in final form upon the
submission thereof to the Florida Insurance Department and New York Insurance
Department, respectively. Seller and Purchaser each agree to promptly make all
other appropriate filings with the Florida Insurance Department or the New York
Insurance Department and such other filings as may be required under the
insurance laws of any other state or jurisdiction in which the Company does
business. The parties hereto will not knowingly take any action that will have
the effect of materially delaying, impairing or impeding the receipt of any
required approvals.

                  (b) Purchaser and Seller will use all their respective
reasonable efforts to assist one another in obtaining any consents referred to
in Sections 9.01(d) and 9.02(d) and any consents referred to in Sections 9.01(e)
and 9.02(e), including, without limitation, providing to such parties such
financial statements and other financial information with respect to Purchaser
as such parties may reasonably request, if and to the extent such information
may reasonably be required; PROVIDED, HOWEVER, that neither Purchaser nor Seller
shall be obligated with respect to such assistance (i) to expend any funds
except the payment of the fees and expenses of any applicable attorneys,
consultants or other advisors retained by it and applicable filing fees and
other costs required by Governmental Authorities, or (ii) to take any actions
with respect to their respective businesses or the Business of the Company
which, in its reasonable judgement, is materially adverse.

                  SECTION 6.05. NO SOLICITATION OF EMPLOYEES. For a period of
18 months following the Closing and other than through ordinary help-wanted
advertising, (a) Seller and its Affiliates shall not, directly or indirectly,
actively solicit or induce any employee of HWCS to leave such employment and
become an employee of Seller or its Affiliates and (b) Purchaser and the Company
shall not, directly or indirectly, actively solicit or induce any employee of
Seller or any Affiliate of Seller (other than HWCS) to leave such employment and
become an employee of the Purchaser or any of its Affiliates; PROVIDED, HOWEVER,
that nothing in this Section 6.05 shall prohibit Seller or any of its Affiliates
or the Purchaser or any of its Affiliates from employing any person who contacts
them on his or her own initiative and without any direct or indirect
solicitation by Seller or any of its Affiliates or Purchaser or any of its
Affiliates, as the case may be.

                  SECTION 6.06. NO SOLICITATION OF OFFERS, ETC. Neither of
Seller nor Humana shall, nor shall it permit any of their respective
subsidiaries to, nor shall they authorize or permit any of their respective
directors, officers or employees or any investment banker, financial advisor,
attorney, accountant or other representative retained by them or any of their
subsidiaries to, directly or indirectly, (i) solicit, initiate or encourage
(including by way of furnishing information), or take any other action designed
to facilitate, any inquiries or the making of any

                                       40

<PAGE>


proposal which constitutes or is likely to lead to any Acquisition Proposal (as
defined below) or (ii) participate in any discussions or negotiations regarding
any Acquisition Proposal. Without limiting the foregoing it is understood that
any violation of the restrictions set forth in the preceding sentence by any
director or officer of any of Humana, Seller, the Company or any of their
respective Affiliates, or any investment banker, financial advisor, attorney,
accountant or other representative of Humana, Seller, the Company or any of
their respective Affiliates, whether or not acting on behalf of Humana, Seller,
the Company or any of their respective Affiliates, shall be deemed a breach of
this Section 6.06 by Seller. For purposes of this Agreement, "ACQUISITION
PROPOSAL" means any inquiry, proposal or offer from any person relating to any
direct or indirect acquisition or purchase of a business that constitutes 15% or
more of the net revenues, net income or assets of the Company, or 15% or more of
any class of equity securities of the Company, or any merger, consolidation,
business combination, recapitalization, liquidation, dissolution or similar
transaction involving the Company, other than the transactions contemplated by
this Agreement.

                  SECTION 6.07. FEES AND EXPENSES. Except as otherwise provided
in this Agreement, all costs and expenses, including, without limitation, fees
and disbursements of counsel, financial advisors and accountants, incurred in
connection with this Agreement and the transactions contemplated hereby shall be
paid by the party incurring such costs and expenses, whether or not the Closing
shall have occurred. All expenses incurred by the Company in connection with
this Agreement for services rendered or costs incurred prior to the Closing,
including, without limitation, expenses and fees of counsel, investment bankers
and other advisors engaged by Company, Humana or Seller prior to the Closing,
shall be borne solely by Seller.

                  SECTION 6.08. INVESTMENT PORTFOLIO. Prior to the Closing Date,
Seller shall update the Investment Portfolio as of the end of each month and
shall deliver the updated Investment Portfolio to Purchaser within ten (10)
Business Days of the end of such month.

                  SECTION 6.09. NOTICE OF CERTAIN MATTERS.

                  (a) Seller covenants and agrees to give prompt notice in
writing to Purchaser of: (i) any information that indicates that any
representation or warranty of Seller contained herein was not true and correct
as of the date hereof or will not be true and correct in any material respect as
of the Closing Date, (ii) the occurrence of any event which will result, or has
a reasonable prospect of resulting, in the failure to satisfy a condition
specified in Article IX hereof, (iii) any notice or other communication from any
third party alleging that the consent of such third party is or may be required
in connection with the transactions contemplated by this Agreement, (iv) any
change in the officers or directors of the Company, (v) any notices or
communication received from the Florida Insurance Department or the New York
Insurance Department, and (vi) any fact, condition or change that, individually

Material Adverse Effect, with respect to Seller or the Company.

                                       41

<PAGE>


                  (b) Seller covenants and agrees to (i) promptly advise
Purchaser of any fact, condition or change that, individually or in the
aggregate, has resulted or is reasonably likely to result in a Material Adverse
Effect on the Company and (ii) notify Purchaser of any emergency or any
governmental complaints, investigations or hearings (or communications
indicating that the same may be contemplated) or adjudicatory proceedings
involving any Property of the Company, and will keep Purchaser fully informed of
such events and permit Purchaser's representatives reasonable access to all
materials prepared in connection therewith in accordance with the terms set
forth in Section 6.02.

                  (c) Purchaser covenants and agrees to give prompt notice in
writing to Seller of: (i) any information that indicates that any representation
or warranty of Purchaser contained herein was not true and correct in any
material respect as of the date hereof or will not be true and correct in any
material respect as of the Closing Date, (ii) the occurrence of any event which
may make the satisfaction of the conditions in Section 9.01 impossible or
unlikely; (iii) any notice or other written communication from any third party
alleging that the consent of such third party is or may be required in
connection with the transactions contemplated by this Agreement; (iv) any
notices or communications received from the Florida Insurance Department or the
New York Insurance Department; and (iv) any fact, condition or change that,
individually or in the aggregate, has resulted or is reasonably likely to result
in a Material Adverse Effect with respect to Purchaser.

                  (d) The giving of any such notice under this Section 6.09 or
the providing of the financial statements contemplated by Section 6.10 shall in
no way change or modify Seller's or Purchaser's representations and warranties
or the conditions to any party's obligations contained herein or otherwise
affect the remedies available to Purchaser or Seller hereunder.

                  SECTION 6.10. INTERIM FINANCIAL STATEMENTS. Seller shall, as
soon as available, but no later than forty-five (45) days after the end of the
relevant month or quarter, as the case may be, deliver promptly to Purchaser any
and all final quarterly financial statements for the Company, audited or
unaudited, prepared for the management of the Company after the date of this
Agreement and prior to the Closing Date. In addition, Sellers will deliver to
Purchaser copies of the audited 1999 Annual Statutory Statement as soon as they
have been delivered by the Company's Auditors.

                  SECTION 6.11. AFFILIATE AGREEMENTS; INTERCOMPANY ACCOUNTS.

                  (a) Except as set forth in Schedule 6.11(a) hereto, Seller
shall cause all intercompany accounts receivable or payable (whether or not
currently due or payable) between (a) the Company, on the one hand, and (b)
Seller or any of its Affiliates (other than the Company), or any of the officers
or directors of Seller and any of its Affiliates, on the other hand, to be
settled in full (without any premium or penalty) at or prior to the Closing.
Within fifteen (15) Business Days prior to the Closing, Seller shall prepare and
deliver to Purchaser a

                                       42

<PAGE>


preliminary statement setting out in reasonable detail the calculation of all
such intercompany account balances as of the Closing based upon the latest
available financial information as of such date. Seller shall provide Purchaser
with supporting documentation verifying the underlying intercompany charges and
transactions. If Purchaser disagrees with the calculation of such intercompany
balances, Purchaser may, within ten (10) Business Days prior to the Closing
Date, deliver a notice to Seller disagreeing with such calculation and setting
forth Purchaser's calculation of such amount. If Purchaser and Seller are unable
to resolve such disagreement within five (5) Business Days thereafter, such
disagreement shall be resolved by independent accountants of nationally
recognized standing reasonably satisfactory to Purchaser and Seller, whose
determination shall be final and conclusive; provided that such dispute shall
not delay the Closing unless the amount in controversy would have a Material
Adverse Effect on the Company or Seller if not resolved on or before the Closing
Date (which when determining whether the matter will have a Material Adverse
Effect, there shall be taken into consideration the fact that such dispute will
be of temporary duration until finally resolved by the selected accounting
firm).

                  (b) All Affiliate Agreements shall be terminated and
discharged without any further liability or obligation thereunder effective at
the Closing, upon terms and pursuant to instruments reasonably satisfactory to
Purchaser and Seller, unless otherwise noted on Section 6.11(b) of the
Disclosure Schedule.

                  SECTION 6.12. COMPANY OBLIGATIONS. Seller agrees that in each
instance in this Agreement where the Company is obligated to act or refrain from
acting under this Agreement during the period prior to the Closing, Seller shall
cause the Company to fulfill such obligations.

                  SECTION 6.13. FURTHER ACTION. Each of the parties hereto shall
execute and deliver such documents and other papers and take such further
actions as may be reasonably required to carry out the provisions hereof and
give effect to the transactions contemplated hereby.

                  SECTION 6.14. COMPLIANCE WITH CONDITIONS. Each party hereto
agrees to cooperate fully with each other party, and shall use its reasonable
best efforts to cause the conditions precedent for which such party is
responsible to be fulfilled. Each party further agrees to use its reasonable
best efforts, and act in good faith, to consummate this Agreement and the
transactions contemplated hereby as promptly as possible.

<PAGE>


plans, programs, arrangements, maintained, sponsored or contributed to (whether
currently or in the past) by the Company, Seller or Humana. Either as a result
of the transactions contemplated herein or otherwise, Purchaser shall not employ
or engage in any manner, and Purchaser shall have no obligations, responsibility
or liabilities to or with respect to, any individual who is or was an employee
or service provider of or to the Company, Seller or Humana (including but not
limited to any individual who currently provides or previously provided services
to the Company pursuant to an arrangement with any management company or similar
entity).

                                  ARTICLE VIII

                                   TAX MATTERS

                  SECTION 8.01. INDEMNITY.

                  (a) Seller agrees to indemnify and hold harmless the Purchaser
and the Company against (i) all Taxes of the Company with respect to any period
or portion thereof that ends on or before the Closing Date, (ii) all Taxes with
respect to any period or portion thereof that begins on or before the Closing
Date which relate to a Tax Return which is filed on a combined, consolidated,
unitary or similar group basis where the Company is or was a member, (iii) all
Taxes imposed on the Seller or any subsidiary or Affiliate of the Seller (other
than the Company), (iv) amounts in respect of Taxes for Pre-Closing Periods for
which the Company may be liable for the Taxes of a Person other than the Company
under Section 1.1502-6 of the Treasury Regulations or any comparable provision
of State, local or foreign law; or as a transferee or successor, by operation of
law or by contract, pursuant to Section 381 of the Internal Revenue Code; or
pursuant to a Tax allocation or sharing agreement, (v) all Taxes imposed as a
result of the Company or any Subsidiary ceasing to be a member of a combined,
consolidated, unitary or similar group and all Taxes imposed as a result of any
transfer of any Subsidiary on or before the Closing Date, (vi) any Tax arising
directly or indirectly from any breach of any representation or warranty of
Seller or Humana contained in Section 4.24 of this Agreement as if such
representation or warranty were made on and as of the Closing Date (other than
any representation or warranty which is not stated to be "as of the date hereof"
and which is specific as to the date when made), without giving effect to any
supplement to the Disclosure Schedule or from any breach of a representation or
a covenant set out in this Article VIII of this Agreement, (vii) all Taxes
(including interest and penalties) imposed on the Company relating to its
acquisition of assets from the Florida Agri-Business and Industries Self
Insurers Fund ("FA&I"), the Florida Business Mutual Insurance Company ("FBM"),
the Florida Builders & Employers Mutual Insurance Company ("FB&E") and Florida
Automobile Dealers Self Insurers Fund ("FADF") and any similar entity to which
the Company is the successor of such entity's liabilities and assets, and (viii)
reasonable liabilities or costs (including legal expenses) resulting from the
foregoing (except as otherwise provided in Section 8.04(b)). Purchaser shall be
responsible for, and hereby agrees to indemnify and hold harmless Seller and its
Affiliates against, Taxes in respect of the Company for which the Purchaser is
not eligible for

                                       44

<PAGE>


indemnification pursuant to the first sentence hereof. Nothing in this Section
8.01 shall be interpreted as requiring the Purchaser to make payments of any
Taxes to any taxing authority before the Closing Date.

                  (b) In the case of Taxes that are payable with respect to a
taxable period (a "Straddle Period") that begins before the Closing Date and
ends after the Closing Date (excluding any such Taxes that are taken into
account in allocating liabilities under Section 8.07), the portion of any such
Tax that is allocable to the relevant portion of the period shall be: (i) in the
case of Taxes that are either (x) based upon or related to income or receipts or
(y) imposed in connection with any sale or other transfer or assignment of
property (real or personal, tangible or intangible) (other than conveyances
pursuant to this Agreement, as provided under Section 8.07), deemed equal to the
amount which would be payable if the taxable period began or ended on the
Closing Date, and (ii) in the case of Taxes imposed on a periodic basis with
respect to the assets of the Company or otherwise measured by the level of any
item, deemed to be the amount of such Taxes for the entire period (or, in the
case of such Taxes determined on an arrears basis, the amount of such Taxes for
the immediately preceding period) multiplied by a fraction the numerator of
which is the number of calendar days in the portion of such period ending on the
Closing Date and the denominator of which is the number of calendar days in the
entire period.

                  SECTION 8.02. RETURNS AND PAYMENTS.

                  (a) Seller shall cause the Company to prepare and timely file
or otherwise furnish to the appropriate party (or cause to be prepared and filed
or so furnished) in a timely manner all Tax Returns with respect to the Company
that are due (taking into account all available extensions) on or before the
Closing Date and all Tax Returns with respect to the Company which are required
to be filed on a combined, consolidated, unitary or similar group basis for any
tax period of the Company that ends on or before the Closing Date, which returns
shall be prepared in a manner consistent with past practice employed by the
Company. Purchaser shall prepare and timely file (or cause the Company to
prepare and timely file) all Tax Returns in respect of the Company that are not
required to be, or caused to be, prepared and filed by Seller hereunder. Tax
Returns prepared by Purchaser for any Straddle Period or for any taxable period
that ends on or prior to the Closing Date shall be prepared in a manner
consistent with past practices employed by Seller (except to the extent counsel
for Purchaser determines there is no reasonable basis in law therefor). With
respect to any Tax Return required to be prepared by Purchaser hereunder and as
to which an amount of Tax is allocable to Seller under Section 8.01(b),
Purchaser shall provide Seller and its authorized representatives with a copy of
such completed Tax Return (with which Purchaser will make available supporting
schedules and information), and a statement and supporting schedules certifying
the amount of Tax shown on such Tax Return that is allocable to Seller pursuant
to Section 8.01(b), at least 20 days prior to the due date (including any
extension thereof) for the filing of such Tax Return, and Seller and its
authorized representatives shall have the right to review such Tax Return and
statement prior to the filing of such Tax Return. Seller and Purchaser agree to
consult and to attempt in good faith to resolve any issues arising as a result
of the review of such Tax Return and statement by Seller

                                       45

<PAGE>


or its authorized representatives; provided that such consultation does not
delay the timely filing of the Tax Return. In the event of a dispute, the party
that is responsible hereunder for the greater amount of Taxes, taking into
account on a net present value basis all open taxable periods affected by the
issue (including future periods in the case of recurring issues), shall have the
right to make the final determination as to any such disputed issue.

                  (b) Seller shall pay or cause to be paid to the appropriate
Tax authority when due and payable all Taxes that are required to be reported on
Tax Returns which are required to be filed by Seller pursuant to subsection (a)
but subject to the right of Seller to be paid amounts in respect of Taxes and to
be indemnified by the Purchaser pursuant to Section 8.01(a). From and after the
Closing Date, the Purchaser shall pay or cause to be paid to the appropriate tax
authority when due and payable all Taxes which accrue with respect to the
Company for any other taxable period (subject to its right of indemnification
from Seller for the Pre-Closing Date portion of any Tax period that includes the
Closing Date pursuant to Sections 8.01(a) and (b)).

                  SECTION 8.03. REFUNDS.

                  Any refunds received by Purchaser or the Company (or any
successor to any of the foregoing) with respect to Taxes of the type for which
Seller is responsible under this Agreement or otherwise (specifically including,
without limiting the kind or scope, refunds, if any, from the current audits of
FA&I, the Company and Humana) shall be for the account of Seller, and Purchaser
shall pay over or cause to be paid over to Seller any such refund or the amount
of any such benefit within ten (10) Business Days of the receipt thereof (in the
case of such a refund) or entitlement thereto (in the case of such an
entitlement). Purchaser shall, if Seller reasonably so requests, cause the
relevant entity to file (including filing in Company, White Mountains, FA&I,
FBM, FB&E & FADF or Purchaser or their affiliate's names, as appropriate) for
any refunds, or equivalent amounts to which Seller is entitled under this
Section 8.03. Purchaser shall permit Seller to control the prosecution of any
such refund claim, and shall cause the relevant entity to authorize by
appropriate power of attorney such persons as Seller shall designate to
represent such entity with respect to such refund claim and Seller shall
reimburse Purchaser for all its reasonable out-of-pocket expenses in connection
therewith, provided that after good faith efforts to resolve any disputes, to
the extent there is any disputed issue with respect to the prosecution of any
such refund claim, control of that issue shall be determined as if the refund
claim were a Tax Return for the purposes of the last sentence of Section
8.02(a). Seller shall pay over to Purchaser any refunds of Taxes for which
Purchaser is responsible under Section 8.02(a) that may be received by Seller or
any of its Affiliates (other than the Company). Notwithstanding anything herein
to the contrary, to the extent any refund is attributable to the carryback of
losses or credits arising in a taxable period beginning after the Closing Date
(the claim for which refund shall be prepared and pursued at Purchaser's
expense), such refund shall be for the account of and belong to Purchaser.

                  SECTION 8.04. TAX CONTESTS.

                                       46

<PAGE>


                  (a) After the Closing, Purchaser shall reasonably promptly
after becoming aware notify Seller in writing of the commencement of any Tax
audit or administrative or judicial proceeding and shall also separately notify
Seller in writing of any demand or claim on Purchaser or the Company which, if
determined adversely to the taxpayer or after the lapse of time would be grounds
for indemnification by Seller under this Article VIII. Such notice shall contain
factual information (to the extent known to Purchaser or the Company) describing
the asserted Tax liability in reasonable detail and shall include copies of any
notice or other document received from any taxing authority in respect of any
such asserted Tax liability. If Purchaser fails to give Seller reasonably prompt
notice of an asserted Tax liability as required by this Section 8.04, then (i)
if Seller is precluded by the failure to give reasonably prompt notice from
contesting the asserted Tax liability in both the administrative and judicial
forums, then Seller shall not have any obligation to indemnify for any loss or
damage arising out of such asserted Tax liability, and (ii) if Seller is not so
precluded from contesting but such failure to give reasonably prompt notice
results in an actual detriment to Seller, then any amount which Seller is
otherwise required to pay Purchaser pursuant to this Article VIII with respect
to such liability shall be reduced by the amount of such detriment.

                  (b) Seller, promptly after receiving notice, may elect to
direct, through counsel of its own choosing and at its own expense, any audit,
claim for refund and administrative or judicial proceeding involving any
asserted liability with respect to which indemnity may be sought against Seller
under this Article VIII (any such audit, claim for refund or proceeding relating
to an asserted Tax liability are referred to herein collectively as a
"CONTEST"). If Seller elects to direct the Contest of an asserted Tax liability,
Purchaser shall cooperate in all reasonable respects and shall cause the Company
or its successor to cooperate in all reasonable respects, at Seller's expense,
in each phase of such Contest. If Seller does not either reasonably promptly
give notice to direct the Contest or commence the direction of the Contest or if
it contests its obligation to indemnify under Section 8.01, Purchaser or the
Company may pay, compromise or contest, at its own expense, such asserted
liability without waiving any of its rights to indemnification hereunder.
However, in such case, neither Purchaser nor the Company may settle or
compromise any asserted liability over the objection of Seller; provided,
however, that Seller's consent to settlement or compromise shall not be
unreasonably withheld or delayed. In any event, each of the Purchaser (or the
Company) and Seller may participate, at its own expense, in the Contest. If
Seller chooses to direct the Contest, Purchaser shall promptly empower and shall
cause the Company or its successor promptly to empower (by power of attorney and
such other documentation as may be appropriate) such representatives of Seller
as Seller may designate to represent Purchaser or the Company or its successor
in the Contest insofar as the Contest involves an asserted Tax liability for
which Seller would be liable under this Article VIII, provided that Seller shall
not, without Purchaser's consent, which shall not be unreasonably withheld or
delayed, (x) agree to any settlement with respect to any Tax if such settlement
would likely materially adversely affect the future Tax liability of Purchaser
or the Company for any periods ending after the Closing Date other than through
the use of losses or credits arising in periods or portions thereof ending on or
prior to the Closing Date or (y) agree to any settlement of such claim or cease
to defend against such claim if, pursuant to or as a result

                                       47

<PAGE>


of such settlement or cessation, injunctive or other equitable relief would be
imposed against Purchaser or the Company. If, with respect to any proposed
settlement referred to in clause (x) of the previous sentence, Seller proposes
in good faith to settle a claim, suit, action or proceeding with respect to any
Tax, which settlement offer is accepted by the relevant taxing authority,
Purchaser may elect to continue to contest such claim, suit, action or
proceeding; provided that notwithstanding how such matter is ultimately settled
or decided, the liability of Seller (including tax, penalty, interest and legal
fees and other expenses) with respect to such claim, suit, action or proceeding
shall be no greater than the amount which would have been payable if Purchaser
had consented to the settlement proposed by Seller.

                  (c) Purchaser shall have the sole obligation and right to
direct, at its own expense, a Contest regarding any Tax Return relating to the
Company for any taxable period commencing after the Closing Date; provided,
however, that Purchaser shall advise and consult with Seller regarding the
status of any such Contest that involves the Company and provided further that,
without the prior written consent of Seller (which shall not be unreasonably
withheld or delayed), and except as provided in Section 8.04(b), Purchaser shall
not (i) make any election, change any annual accounting period or adopt or
change any accounting method if any such election, adoption or change would have
the effect of increasing the tax liability of Seller in any tax period or
portion thereof ending on or before the Closing Date, or (ii) file any amended
return, enter into any closing agreement, settle any tax claim or assessment
relating to the Company, surrender any right to claim a refund of Taxes, consent
to any extension or waiver of the limitation period applicable to any tax claim
or assessment relating to the Company or take any action, if any such amendment,
agreement, settlement, surrender, consent or other action would have the effect
of increasing the tax liability of Seller in any tax period or portion thereof
ending on or before the Closing Date, except to the extent Seller is to be fully
paid or reimbursed for, or indemnified by Purchaser against, any such increase
under Sections 8.05 or 11.02 of this Agreement, or otherwise.

                  (d) Regardless of whether a Contest is commenced, if Seller
becomes aware of the commencement of any Tax audit or administrative or judicial
proceeding which could result in any liability for which Seller has agreed to
indemnify Purchaser or the Company pursuant to the provisions of Section
8.01(a), Seller shall reasonably promptly so inform Purchaser in writing (if it
has not previously done so).

                  SECTION 8.05. CERTAIN AUDIT ADJUSTMENTS.

                  (a) If an audit adjustment, claim for refund or amended return
("Adjustment"), after the date hereof shall both increase a Tax liability which
is allocated to Seller under Section 8.01 or otherwise the responsibility of
Seller (or reduce losses or credits otherwise available to Seller) for a period
or portion thereof ending on or before the Closing Date and decrease a Tax
liability which is allocable to Purchaser for a period or portion thereof ending
after the Closing Date, then, when and to the extent that Purchaser (or the
Company) derives a benefit from such decrease (through a reduction of Taxes,
refund of Taxes paid or credit against

                                       48

<PAGE>


Taxes due), Purchaser shall promptly pay to Seller an amount equal to the amount
of such refund, reduction or credit (unless Seller has previously been
compensated for such benefit under this Article VIII). Similarly, if an
Adjustment shall both decrease a Tax liability which is allocated to Seller
under this Section 8.05 or otherwise is the responsibility of Seller for a
period or portion thereof ending on or before the Closing Date and increase the
Tax liability which is allocable to Purchaser (or reduce losses or credits
otherwise available to Purchaser) for a period or portion thereof ending after
the Closing Date, then, when and to the extent that Seller or its Affiliate
derives a benefit from such decrease (through a refund or reduction of Taxes
paid or credit against Taxes due), Seller shall promptly pay to Purchaser an
amount equal to the amount of such refund, reduction or credit. In the event
that a benefit derived from an increase in a Tax liability allocable to either
Purchaser or Seller pursuant to an Adjustment is negated due to a subsequent
Adjustment or net operating loss carryback after either Purchaser or Seller has
paid such benefit to the other party, as the case may be, such benefit shall be
repaid to the original payor, subject to return to such other party if and when
the benefit again becomes available.

                  SECTION 8.06. COOPERATION AND EXCHANGE OF INFORMATION.

                  Seller and Purchaser will provide each other with such
cooperation and information as either of them reasonably may request of the
other in filing any Tax Return, amended return or claim for refund, determining
a liability for Taxes or a right to a refund of Taxes or participating in or
conducting any audit or other proceeding in respect of Taxes. Such cooperation
and information shall include providing copies of relevant Tax Returns or
portions thereof, together with accompanying schedules and related work papers
and documents relating to rulings or other determinations by taxing authorities,
but in no event shall either party be required to disclose to the other party
any information relating to its operations other than the Company. Seller and
Purchaser shall make their employees available on a mutually convenient basis to
provide explanations of any documents or information provided hereunder. Seller
and Purchaser will retain all Tax Returns, schedules and work papers and all
material records or other documents relating to Tax matters of the Company for
its taxable period first ending after the Closing Date and for all prior taxable
periods and future federal income tax returns to the extent relevant to Sections
8.10(d) and 8.10(e) until the later of: (i) the expiration of the statute of
limitations of the taxable periods to which such returns and other documents
relate, without regard to extensions except to the extent notified by the other
party in writing of such extensions for the respective Tax periods; or (ii) six
years (or such longer period as needed for purposes of Section 8.10(d) or
8.10(e)) following the due date (without extension) for such returns. After such
time, before either Seller or Purchaser shall dispose of any of such books and
records, at least ninety calendar days prior written notice to such effect shall
be given to the other party, and such other party shall be given an opportunity,
at its cost and expense, to remove and retain all or any part of such books and
records as such party may select; provided, however, that in no event shall
either party be required to disclose to the other party any information relating
to its operations other than the Company. Any information obtained under this
Section 8.06 shall be kept confidential, except as may be otherwise necessary in
connection with the filing of returns or claims for refund or in conducting an
audit or other proceeding.

<PAGE>


                  SECTION 8.07. CONVEYANCE TAXES.

                  Seller agree to assume liability for and to hold Purchaser
harmless against any sales, use, transfer, stamp, stock transfer, real property
transfer or gains, and value added taxes, any transfer, registration, recording
or other fees in the nature of Taxes incurred as a result of the transactions
contemplated hereby, and shall file such applications and documents as shall
permit any such Tax to be assessed and paid on or prior to the Closing Date in
accordance with any available pre-sale filing procedure.

                  SECTION 8.08. FIRPTA CERTIFICATE.

                  Sellers shall deliver or cause to be delivered to Purchaser on
the Closing Date a FIRPTA Certificate duly executed by the Company and in form
and substance reasonably satisfactory to Purchaser.

                  SECTION 8.09. TAX SHARING AGREEMENT.

                  Any Tax Sharing Agreement shall terminate with respect to the
Company on the Closing Date, with the Company having no further payment
obligation or rights under such agreement on or after the Closing Date. No
payments shall be made by the Company, Seller, Humana or their affiliates under
the Tax Sharing Agreement for year 1999 and year 2000.

                  SECTION 8.10. NET OPERATING LOSS.

                  (a) Humana, Seller, Purchaser and the Company will file a
timely election to have Seller and Humana retain net operating loss carryovers
or capital loss carryovers of the Company under the Internal Revenue Code and
Treas. Reg. Section 1. 1502-20(g) (and any corresponding provision of State or
local tax law) in an amount equal to the excess, if any, of (i) Aggregate
Company Taxable Income over (ii) Seller Utilized Losses. If as a result of an
audit or otherwise, it is subsequently determined that the amount of the excess
of Aggregate Company Taxable Income over Seller Utilized Losses has increased
from the amount retained by Seller and Humana pursuant to the preceeding
sentence, Purchaser shall pay to Seller any tax benefit from such excess losses
each time that Purchaser, the Company or their affiliates utilize such excess
losses. The parties may, but are not required to, agree to have Humana and
Seller retain a greater amount of net operating losses, and for an appropriate
payment to be made therefor.

                  (b) Humana and Seller will file a timely election under
Internal Revenue Code Treas. Reg. Sections 1.1502-95(b)(2), Reg.1.1502-95(c) and
1.1502-95 (e) (and any corresponding provision of State or local tax law) to
apportion an amount of Humana's and Seller's Section 382 limitation from the
September 8, 1997 acquisition of Seller's predecessor by means of a merger of
such predecessor into Seller, a newly-formed subsidiary of Humana, to the
Company equal to the limitation to which the Company or Purchaser is subject
under Section

                                       50

<PAGE>


382(c) of the Code as a result of the acquisition of the Company by Purchaser.
At Purchaser's request, Seller will join Purchaser in making any election
required under Treas. Reg. Sections 1.1502-95(b)(2), 1.1502-95(c) or
1.1502-95(e) (and any corresponding provision of State or local tax law).

                  (c) On or before November 1, 2000, Humana and the Seller shall
promptly make a payment to Purchaser equal to an estimate made by Seller in good
faith of the Tax Payment. On or before October 1, 2001 the Tax Payment shall be
recalculated based upon the information contained in the tax returns of the
Company. If the Tax Payment as recalculated has increased from the amount used
to make the estimated Tax Payment, Humana and the Seller shall promptly make a
payment to the Purchaser of such excess, with interest from November 1, 2000. If
the Tax Payment as recalculated has decreased from the amount used to make the
estimated Tax Payment, the Purchaser shall promptly make a payment to the Seller
of such decrease, with interest from November 1, 2000. If, as a result of an
audit or otherwise, it is subsequently determined that the amount of the excess
of the Seller Utilized Losses over Aggregate Taxable Income has increased from
the amount used to make the recalculated Tax Payment under either of the
preceding two sentences, Humana and the Seller shall promptly make a payment to
Purchaser equal to the increase in the Tax Payment as further recalculated with
interest from November 1, 2000. If as a result of an audit or otherwise, it is
subsequently determined that the amount of the excess of Seller Utilized Losses
over Aggregate Company Taxable Income has decreased from the amount used to make
the recalculated Tax Payment under the second or third preceeding sentence, the
Purchaser shall promptly make a payment to Seller equal to any decrease in the
Tax Payment as further recalculated with interest from November 1, 2000,
provided that (i) the aggregate amounts of any payment by Purchaser to Seller
under this sentence (determined without regard to interest) shall not exceed the
the aggregate Tax Payments received by Purchaser (determined without regard to
interest) and (ii) Purchaser shall not be required to make a payment to the
extent that it is unable to utilize the associated net operating loss or capital
loss carryovers as a result of the expiration of applicable statute of
limitiations. In the event that an election is not required to be made under
Section 8.10(a) and either (A) Purchaser is not required to make a payment to
Seller under this paragraph as a result of clause (i) in the proviso in the
preceeding sentence or (B) as a result of an audit or otherwise, it is
subsequently determined that Aggregate Company Taxable Income exceeds Seller
Utilized Losses, Purchaser shall pay to Seller any tax benefit from such excess
losses each time that Purchaser, the Company or their affiliates utilize such
excess losses. For the purpose of this paragraph, interest shall be calculated
using an interest rate equal to the interest rate on one year United States
Treasury Bills as of November 1, 2000 plus 50 basis points, compounded annually.

                  (d) Purchaser shall pay an amount equal to the federal income
tax benefit obtained by Purchaser, the Company and their affiliates from the use
of the Company's net operating loss carryover which existed at December 31,
1998, to the extent that the aggregate federal income tax benefit from the
Company's net operating loss carryover exceeds the sum of (i) $2,000,000 PLUS
(ii) the federal income tax benefits which would have been obtained by

                                       51

<PAGE>


Purchaser, the Company and their affiliates if the Company's net operating loss
carryover had been $67,000,000 at December 31, 1998. Such payment shall be
promptly made to Humana each time after Purchaser, the Company or their
affiliates utilize such excess federal income tax benefits less any prior
payments made to Humana under this Section 8.10(d). If and only if the net
operating loss carryover utilized by the Purchaser, the Company or their
affiliates shall exceed $70,000,000 at December 31, 1998, then, within a
reasonable time after the Company's, the Purchaser's or any of their affiliate's
filing of federal income tax returns which utilize any such loss, then the
Purchaser (or other appropriate entity) shall furnish Humana a schedule setting
forth the annual uses of such loss and the loss remaining to be used.

                  (e) Seller shall pay an amount equal to the federal income tax
benefit not obtained by Purchaser, the Company and their affiliates from the use
of the Company's net operating loss carryover which existed at December 31,
1998, to the extent that the aggregate federal income tax benefit from the
Company's net operating loss carryover is less than the difference between (i)
the federal income tax benefits which would have been obtained by Purchaser, the
Company and their affiliates if the Company's net operating loss carryover had
been $66,000,000 at December 31, 1998, and (ii) $2,000,000. Such payment shall
be promptly made to the Company each time after Purchaser, the Company or their
affiliates file a return which would have utilized a federal income tax benefit
had the Company's net operating loss at December 31, 1998 been $66,000,000, to
the extent the aggregate lost benefits exceed $2,000,000 plus any prior payments
made to Company under this Section 8.10(e). Prior to claiming a payment under
this paragraph, the Purchaser (or other appropriate entity) shall furnish Humana
a schedule setting forth the annual uses of such loss and the loss remaining to
be used.

                  (f) Definitions. For purposes of this Section 8.10, the
following terms shall have the following definitions:

                      (1) "Company 1999 Taxable Income" shall mean the lesser of
(i) the actual separate company U.S. Federal taxable income of the Company for
1999 (determined without regard to any net operating or capital loss carryback
of the Company for any taxable period beginning after the Closing Date) and (ii)
$21 million.

                      (2) "Company 2000 Taxable Income" shall mean the lesser of
(i) the actual separate company U.S. Federal taxable income of the Company for
2000 for the Pre-Closing Period, determined by excluding any net capital gains
resulting from dispostions not directed by the Purchaser and its Affiliates, the
excess, if any, of net capital losses over net capital gains resulting from
dispositions directed by the Purchaser or its Affiliates prior to the Closing,
any extraordinary reserve releases or adjustments and any net operating or
capital loss carryback of the Company for any taxable period beginning after the
Closing Date and (ii) $20 million multiplied by a fraction, the numerator of
which is the number of calendar days in 2000 preceding the Closing Date and the
denominator is 366.

                                       52

<PAGE>


                      (3) "Aggregate Company Taxable Income" shall equal the sum
of Company 1999 Taxable Income and Company 2000 Taxable Income.

                      (4) "Seller Utilized Losses" shall mean an amount equal to
the portion of the net operating loss carryovers and capital loss carryovers of
the Company that have been utilized by the Humana U.S. federal consolidated
return group during 1999 and 2000.

                      (5) "Tax Payment" shall mean a dollar amount equal to
38.575% multiplied by 85% multiplied by the excess of (i) Seller Utilized Losses
over (ii) Aggregate Company Taxable Income.

                  SECTION 8.11. MISCELLANEOUS.

                  Seller and Purchaser agree to treat all payments made by
either to or for the benefit of the other (including any payments to the
Company) under this Article VIII and under other indemnity provisions of this
Agreement, as adjustments to the purchase price or as capital contributions for
Tax purposes and that such agreed treatment shall govern for Tax purposes
hereof.

                                   ARTICLE IX

                              CONDITIONS TO CLOSING

effect as if made as of the Closing Date, other than such representations and
warranties as are made as of another date, which shall be true and correct in
all respects as of such date, except where the failure of any representation or

covenants contained in this Agreement to be complied with by Purchaser on or
before the Closing shall have been complied with in all material respects.
Nothing set forth herein or in the certificate to be delivered by Seller at

Agreement

                  (b) HSR ACT. Any waiting period (and any extension thereof)

<PAGE>


been terminated without action by the Federal Trade Commission or Department
of Justice which would cause a Material Adverse Effect on Seller or of any of

Agreement shall have been obtained and be in effect on the Closing Date
(including, but not limited to, the approval of the Florida Insurance Department
and any approvals which may be required under the insurance laws of any
jurisdiction in which the Company does business), except to the extent that the
failure to obtain any such consent would not have the effect of making the

Seller, the Consent Orders shall have been modified to permit the transactions
contemplated herein and Seller, Humana and any of their Affiliates (other than
the Company) shall have fully and unconditionally released and discharged from
all obligations and liabilities under such Consent Order and any other orders in

such transactions, and would not result in a material liability to Seller; and

                  (f) PROCEEDING. All proceedings, corporate or otherwise, taken
by Purchaser in connection with the transactions contemplated hereby and all
instruments and documents incident thereto shall be reasonably satisfactory in
form and substance to Seller and its counsel.

                  SECTION 9.02. CONDITIONS TO OBLIGATIONS OF PURCHASER. The

                                       54

<PAGE>


warranties of Seller and Humana contained in this Agreement shall be true and
correct in all respects as of the Closing Date with the same force and effect as
if made as of the Closing Date, other than such representations and warranties
as are made as of another date, which shall be true and correct in all respects
as of such date, except where the failure of any representation or warranty to
be true or correct would not have the effect of making the transactions
contemplated by this Agreement illegal and would not have, either individually
or in the aggregate, a Material Adverse Effect on the Company. With respect to
the representations set forth in Section 4.24 of this Agreement stated as to be
made of the date hereof, such representation shall be deemed to be made as of
the Closing Date. All covenants contained in this Agreement to be complied with
by Seller and Humana on or before the Closing shall have been complied with in
all material respects. Nothing set forth in this Section 9.02(a) or in the
certificate of Purchaser to be delivered at Closing pursuant to Section
2.05(b)(ii) shall limit the right of Purchaser to be indemnified by Seller
pursuant to Sections 10.03(a)(ii) or 10.03(a)(iii) of this Agreement.

                  (b) HSR ACT. Any waiting period (and any extension thereof)
under the HSR Act applicable to the purchase of the Shares contemplated hereby
shall have expired or shall have been terminated without any action by the
Federal Trade Commission or the Department of Justice which would have a
Material Adverse Effect on the Company, Purchaser or any Affiliate of Purchaser;

                  (c) NO ORDER OR SUIT. No Governmental Authority shall have
enacted, issued, promulgated, enforced or entered any statute, rule, regulation,
injunction or other order (whether temporary, preliminary or permanent) which is
in effect and has the effect of making the transactions contemplated by this
Agreement illegal or otherwise restraining or prohibiting consummation of such
transactions or which would have a Material Adverse Effect on the Company,
Purchaser or any of its Affiliates; provided, that the parties hereto shall use
their reasonable best efforts to have any such order or injunction vacated;

                  (d) GOVERNMENTAL FILINGS AND CONSENTS. All governmental
orders, approvals and consents to the transactions contemplated by this
Agreement shall have been obtained and be in effect on the Closing Date
(including, but not limited to, the approval of the Florida Insurance Department
and the New York Insurance Department and any approvals which may be required
under the insurance laws of any jurisdiction in which the Company does
business), except to the extent that the failure to obtain any such consent,
individually and in the aggregate, would not have a Material Adverse Effect.
Such approvals as shall have been obtained shall not impose upon Purchaser, the
Company or any of the Purchaser's Affiliates any conditions or other
requirements which would cause any material additional costs or materially
interfere with the continued operations of the business of the Purchaser, its
Affiliates or the Company as currently conducted. As of the date hereof, the
Company is subject to the Consent Orders of the Florida Insurance Department. To
the extent the Company seeks modification of either of the Consent Orders or any
order relative to the transactions described in this Agreement, such modified
Consent Orders or other orders shall be in all respects reasonably satisfactory
to Purchaser. In addition, the Amended and Restated Management Contract shall
have been approved by the

                                       55

<PAGE>


Florida Insurance Department if required upon substantially the same terms as
the Amended and Restated Management Contract attached hereto;

                  (e) THIRD PARTY CONSENT. Purchaser shall have received the
third party consents, approvals, authorizations or actions to the transactions
contemplated by this Agreement, if any, in form and substance reasonably
satisfactory to Purchaser from the parties listed in Section 9.02(e) of the
Disclosure Schedule, except to the extent that the failure, individually and in
the aggregate, to obtain any such consents would not have a Material Adverse
Effect;

                  (f) RESIGNATION OF DIRECTORS AND CERTAIN OFFICERS OF THE
COMPANY. Purchaser shall have received the resignations, effective as of the
Closing, of all the directors and officers of the Company;

                  (g) NO MATERIAL ADVERSE EFFECT. Since the date of this
Agreement, no event or events shall have occurred which, individually or in the
aggregate, have, or are reasonably likely to have, had a Material Adverse Effect
with respect to the Company;

                  (h) MINUTE AND STOCK RECORDS. The Purchaser shall have
received evidence reasonably satisfactory to it that the complete and correct
minute books and stock certificate and record books (with all canceled and
unused stock certificates attached) and the corporate seals of the Company are
in the possession of the Person designated at least two (2) Business Days prior
to the Closing by the Purchaser to Seller in writing;

                  (i) AMENDED AND RESTATED MANAGEMENT CONTRACT. HWCS shall have
entered into the Amended and Restated Management Contract; and

                  (j) PROCEEDINGS. All proceedings, corporate or otherwise,
taken by Seller or Humana in connection with the transactions contemplated
hereby and all instruments and documents incident thereto shall be reasonably
satisfactory in form and substance to Purchaser and its counsel.

                                    ARTICLE X

                      INDEMNIFICATION & CERTAIN LITIGATION

                  SECTION 10.01. SURVIVAL. All agreements made by the parties in
this Agreement and the right to recover for breach of the representations,
warranties and covenants and agreements of the parties hereto contained herein
shall survive the Closing, regardless of any investigation made by or on behalf
of Seller or Purchaser, for the periods set forth in this Article X.
Notwithstanding anything in Article VIII or in any other provision of this
Agreement to the contrary, the representations and warranties in Section 4.24
respecting the liability of the

                                       56

<PAGE>


Company for Taxes shall continue to survive until all taxable periods of the
Company to and including the Closing Date shall be closed to any further
assessment of Taxes and to any assessment of any penalties or interest charges
in respect of any such Taxes, by receipt of a final assessment, in form and
substance reasonably satisfactory to Purchaser, from the appropriate tax
authorities, or by the expiration of the applicable statute of limitations or
any extension thereof by waiver or otherwise. After the Closing, all claims,
whether in Contract, tort or otherwise, relating to or resulting from a breach
of any representation, warranty, covenant or agreement contained in this
Agreement (except for claims relating to or resulting from the guarantee of
Humana as set forth in Article XII, and except for claims for injunctive or
other equitable relief for which monetary damages covered by an indemnity set
forth herein are not available) shall be made exclusively under, and subject to
the limitations set forth in this Article X. Notwithstanding anything in Article
X or any other term or provision of this Agreement to the contrary, after the
Closing, all claims, whether in Contract, tort or otherwise, relating to or
resulting from a breach of any representation, warranty or covenant relating to
Taxes contained in this Agreement (except for claims relating to or resulting
from the guarantee of Humana as set forth in Article XII, and except for claims
for injunctive or other equitable relief for which monetary damages covered by
an indemnity set forth in Article VIII of this Agreement are not available)
shall be made exclusively under, and subject to the limitations set forth in,
Article VIII and, as to limitations on the timing of such claims, this Section
10.01, Section 10.02(b)(iii) or Section 10.03(b)(iii) of this Agreement, as
applicable.

                  SECTION 10.02. INDEMNIFICATION BY PURCHASER

                  (a) Purchaser agrees, subject to the limitations, conditions
and other terms and conditions of this Article X, to indemnify Seller and its
Affiliates, and the respective officers, directors, employees, agents, heirs,
successors and assigns of Seller and its Affiliates (as used in this Section
10.02, each an "INDEMNIFIED PARTY") against and to defend and hold them harmless
from, and shall pay to such Indemnified Parties the amount of all Damages
arising directly or indirectly, from or in connection with: (i) any breach of
any representation or warranty of Purchaser set forth in this Agreement; (ii)
any breach of any representation or warranty of Purchaser in this Agreement as
if such representation or warranty were made on and as of the Closing Date
(other than any representation or warranty which is specific as to the date when
made), without giving effect to any supplement to the Disclosure Schedule; (iii)
a breach by Purchaser of any covenant, agreement or obligation set forth in this
Agreement (excluding, however, from this Section 10.02, a breach of a covenants
set forth in Article VIII); and (iv) the conduct of the Business by Purchaser
following the Closing. No claim may be asserted nor may any action be commenced
against Purchaser under this Section 10.02 for breach of any representation,
warranty, covenant or agreement contained herein, unless written notice of such
claim or action is received by Purchaser describing in reasonable detail the
facts and circumstances known to Seller or any other Indemnified Party with
respect to the subject matter of such claim or action on or prior to the date on
which the representation, warranty, covenant or agreement on which such claim or
action is based ceases to survive as set forth in

                                       57

<PAGE>


Section 10.02(b)(iii), irrespective of whether the subject matter of such claim
or action shall have occurred before or after such date and any claim made by
Seller or any other Indemnified Party under this Section 10.02 within the
aforesaid time periods shall be considered timely made even if such claim is not
resolved until after the expiration of the aforesaid periods.

                  (b) The obligations of Purchaser set forth in Section 10.02(a)
shall be subject to the following limitations and restrictions:

                  (i) Purchaser shall not be obligated to indemnify the
         Indemnified Parties until such time as the total sum of the Damages
         shall exceed $2,500,000, at which time Purchaser shall indemnify the
         Indemnified Parties for only the amount of the Damages in excess of
         $2,500,000, PROVIDED, HOWEVER, that this limitation shall not apply
         with respect to any Damages arising from or in connection with breach
         of any representation or warranty contained in Section 5.01 or a breach
         of the covenants set forth in Article VIII, and shall not apply to a
         breach or failure of performance of any of the payment obligations set
         forth in Section 2 of this Agreement, all of which shall be indemnified
         on a dollar-for-dollar basis.

                  (ii) The aggregate amount of Purchaser's liability under
         Section 10.02 with respect to all claims for indemnification or other
         relief thereunder, shall not exceed an amount equal to fifty percent
         (50%) of the Adjusted Purchase Price, PROVIDED, HOWEVER, that this
         limitation shall not apply with respect to any Damages arising from or
         in connection with breach of any representation or warranty contained
         in Section 5.01 or a breach of the covenants set forth in Article VIII,
         and shall not apply to a breach or failure of performance of any of the
         payment obligations set forth in Section 2 of this Agreement.

                  (iii) Purchaser shall have no liability with respect to any
         claim or other assertion of a right to recover Damages for any breach
         of the representations, warranties and covenants of Purchaser contained
         in this Agreement, unless such Indemnified Parties deliver to Purchaser
         notice of such matter within two (2) years after the Closing Date,
         except for (x) any breach of an agreement or covenant which, by its
         terms, is to be performed after the Closing Date, for which
         indemnification shall be required if such Indemnified Parties deliver
         notice at any time prior to expiration of the applicable period under
         the statute of limitations therefor, and (y) any breach of a
         representation and warranty contained in Section 5.01, for which there
         shall be no time limitations in which such Indemnified Parties must
         deliver notice to Purchaser to be entitled to indemnification from
         Purchaser under Section 10.02(a).

                  (iv) Payments by Purchaser pursuant to Section 10.02(a) shall
         be limited to the amount of any Damages that remains after deducting
         therefrom any insurance proceeds and any indemnity, contribution or
         other similar payment recoverable by the Indemnified Party from any
         third party with respect thereto; PROVIDED, HOWEVER, that the

                                       58

<PAGE>


         reduction for insurance proceeds shall itself be reduced by the present
         value of Seller's reasonably estimated increase in insurance costs
         directly attributable to the claim in respect of which such insurance
         proceeds shall have been received for the five years following the
         receipt of such proceeds using a discount rate of six percent.

                  (c) An Indemnified Party shall give Purchaser prompt written
notice of any claim, assertion, event or proceeding by or in respect of a third
party of which an Indemnified Party has knowledge concerning any liability or
damage as to which an Indemnified Party may request indemnification hereunder.
Failure to give such notice shall not waive any right to indemnification on the
part of the Indemnified Party or Parties who fail to give such notice, except
only to the extent of any Damages actually suffered by Purchaser or any of its
Affiliates by reason of the delay in receiving such notice. Purchaser shall have
the right to direct, through counsel of its own choosing, provided such counsel
is reasonably satisfactory to the Indemnified Party, the defense or settlement
of any such claim or proceeding at its own expense, provided that Purchaser
vigorously and diligently pursues such defense in good faith and keeps the
Indemnified Party and its attorneys reasonably informed as to the progress of
the defense and any proposed settlement. If Purchaser elects to assume the
defense of any such claim or proceeding, the Indemnified Party may participate
in such defense, but in such case the expenses of the Indemnified Party shall be
paid by the Indemnified Party. Notwithstanding the foregoing, if an Indemnified
Party determines in good faith that there is a reasonable probability that any
such claim or proceeding may adversely affect it or its Affiliates other than as
a result of monetary damages for which it or its Affiliates would be entitled to
indemnification under this Agreement, such Indemnified Party may, by notice to
Purchaser, assume the exclusive right to defend, compromise, or settle such
claim or proceeding, but Purchaser will not be bound by any determination of
such claim or proceeding so defended or any compromise or settlement effected
without its consent (which may not be unreasonably withheld or delayed). The
Indemnified Party shall provide Purchaser with access to such Indemnified
Party's records and personnel relating to any such claim, assertion, event or
proceeding during normal business hours and shall otherwise cooperate with
Purchaser in the defense or settlement thereof, and Purchaser shall reimburse
the Indemnified Party for all the reasonable out-of-pocket expenses of such
Indemnified Party in connection therewith. If Purchaser elects to direct the
defense of any such claim or proceeding, the Indemnified Party shall not pay, or
permit to be paid, any part of any claim or demand arising from such asserted
liability, (i) unless Purchaser consents in writing to such payment which
consent shall not be unreasonably withheld, or (ii) unless Purchaser, subject to
the last sentence of this Section 10.02(c), withdraws from the defense of such
asserted liability, or (iii) unless a final judgment from which no appeal may be
taken by or on behalf of Purchaser is entered against the Indemnified Party for
such liability, or (iv) unless there is a material risk if such asserted
liability is not paid then that an injunction or other equitable relief will be
granted which will have a Material Adverse Effect on Seller or any of its
Affiliates. Without the prior written consent of the Indemnified Parties (such
consent not to be unreasonably withheld), Purchaser shall not enter into any
settlement of any claim or proceeding; PROVIDED HOWEVER, that , if pursuant to
or as a result of such settlement (x) injunctive or other equitable relief would
be imposed against the Indemnified Parties, or any of them, or (y) such
settlement,

                                       59

<PAGE>


in the reasonable judgment of the Indemnified Parties, would have a Material
Adverse Effect on such Indemnified Parties or any Affiliate of such Indemnified
Parties for which it is not entitled to indemnification hereunder, or (z) such
settlement does not include a general release to all Indemnified Parties, then
such settlement shall require the prior written consent of the Indemnified
Parties. If Purchaser shall fail to defend any claim or proceeding that it has a
duty to defend hereunder, or if, after commencing or undertaking any such
defense, Purchaser fails to diligently prosecute and defend or withdraws from
such defense, or if Purchaser cannot reasonably defend the Indemnified Party due
to conflicts of interest or conflicts between the defense that it must assert on
behalf of the Indemnified Parties and the defense it must assert to protect its
interests in such claim or proceeding, the Indemnified Party shall have the
right to undertake the defense or settlement thereof, at Purchaser's expense. If
the Indemnified Party assumes the defense of any such claim or proceeding
pursuant to this Section 10.02(c) and proposes to settle such claim or
proceeding prior to a final judgment thereon or to forego appeal with respect
thereto, then the Indemnified Party shall give Purchaser prompt written notice
thereof and Purchaser shall have the right to participate in the settlement or
assume or reassume the defense of such claim or proceeding subject to the
conditions set forth above; provided that if Purchaser does not assume or
reassume the defense within ten (10) Business Days or any earlier time that such
offer to settle expires then the Indemnified Party can settle such claim in good
faith without the consent of Purchaser.

                  (d) Except as embodied and set forth in this Agreement, the
Disclosure Schedule, the certificates delivered pursuant to Article IX or any
agreement executed and delivered pursuant to the provisions hereof, Purchaser is
not making any representation, warranty, covenant, promise or agreement with
respect to the matters contained herein or therein. Anything herein to the
contrary notwithstanding, no breach of any representation, warranty, covenant or
agreement contained herein or therein shall give rise to any right on the part
of the Indemnified Party, after the consummation of the purchase and sale of the
Shares contemplated by this Agreement, to rescind this Agreement or any of the
transactions contemplated hereby.

                  SECTION 10.03. INDEMNIFICATION BY SELLER.

                  (a) Seller agrees, subject to the limitations, conditions and
other terms and conditions of this Article X, to indemnify Purchaser and its
Affiliates and their respective officers, directors, employees, agents, heirs,
successors and assigns (as used in this Section 10.03, each an "INDEMNIFIED
PARTY") against and hold them harmless from, and shall pay, all Damages arising
directly or indirectly, from or in connection with:(i) any breach of any
representation or warranty of Seller or Humana set forth in this Agreement
(excluding, however, from this Section 10.03, a breach of a representation or
warranty set forth in Section 4.24); (ii) any breach of any representation or
warranty of Seller or Humana in this Agreement as if such representation or
warranty were made on and as of the Closing Date (other than any representation
or warranty which is specific as to the date when made), without giving effect
to any supplement to the Disclosure Schedule (excluding, however, from this
Section 10.03, a breach of a representation or warranty set forth in Section
4.24); (iii) a breach by Seller of any

                                       60

<PAGE>


covenant, agreement or obligation set forth in this Agreement (excluding,
however, from this Section 10.03, a breach of a covenants set forth in Article
VIII); and (iv) any and all liabilities (including, without limitation, any
liability for premium payments or premium refunds, but excluding any taxes
covered by Article VIII) arising, directly or indirectly, from or in connection
with any Assumed Portfolio Transactions (including, without limitation, claims
arising under, or related to, the underlying Insurance Policies and Contracts
relating to such Assumed Portfolio Transactions), other than (A) liabilities for
workers' compensation insurance claims and related expenses arising from such
Assumed Portfolio Transactions and (B) liabilities arising with respect to such
Assumed Portfolio Transactions as a result of the actions of Purchaser or the
Company following the Closing, and (v) any and all liabilities for any fines or
penalties imposed by the Florida Insurance Department for any violation of any
order applicable to the Company, which violation occurred prior to the Closing.
No claim may be asserted nor any action commenced against Seller under this
Section 10.03 for breach of any representation, warranty, covenant or agreement
contained herein, unless written notice of such claim or action is received by
Seller describing in reasonable detail the facts and circumstances known to
Purchaser or any other Indemnified Party with respect to the subject matter of
such claim or action on or prior to the date specified in this Section
10.03(b)(iii), irrespective of whether the subject matter of such claim or
action shall have occurred before or after such date; and any claim made by
Purchaser or any other Indemnified Party under the provisions of this Section
10.03 within the aforesaid time periods shall be considered timely made even if
such claim is not resolved until after the expiration of the aforesaid periods.

                  (b) The obligations of Seller set forth in Section 10.03(a)
shall be subject to the following limitations and restrictions:

                  (i) Seller shall not be obligated to indemnify the Indemnified
         Parties until such time as the total sum of the Damages shall exceed
         $2,000,000, at which time Seller shall indemnify the Indemnified
         Parties for only the amount of the Damages in excess of $2,000,000;
         PROVIDED, HOWEVER, that this limitation shall not apply with respect to
         any Damages arising from or in connection with a breach of any
         representation or warranty contained in Section 4.01, Section 4.02,
         Section 4.12, Section 4.22, Section 4.23 and Section 4.24, a breach of
         the covenants set forth in Article VII or Article VIII, and shall not
         apply to breach or failure of performance of any of the payment
         obligations set forth in Section 2 of this Agreement, all of which
         shall be indemnified on a dollar-for-dollar basis; PROVIDED, FURTHER,
         that Seller shall not be obligated to indemnify the Indemnified Parties
         with respect to matters relating to Section 10.03(b)(iv) until such
         time as the total sum of the Damages shall exceed $500,000, at which
         time Seller shall indemnify the Indemnified Parties for only the amount
         of the Damages in excess of $500,000.

                  (ii) The aggregate amount of Seller's liability under Section
         10.03 with respect to all claims for indemnification or other relief
         thereunder, shall not exceed an amount equal to fifty percent (50%) of
         the Adjusted Purchase Price, PROVIDED, HOWEVER, that this limitation
         shall not apply with respect to any Damages arising from or in

                                       61

<PAGE>


         connection with breach of any representation or warranty contained in
         Section 4.01, Section 4.02, Section 4.12, Section 4.22, Section 4.23
         and Section 4.24, a breach of the covenants set forth in Article VII
         and Article VIII, and shall not apply to breach or failure of
         performance of any of the payment obligations set forth in Section 2 of
         this Agreement.

                  (iii) Seller shall have no liability with respect to any claim
         or other assertion of a right to recover Damages for any breach of the
         representations, warranties and covenants of Seller or Humana contained
         in this Agreement, unless such Indemnified Parties deliver to Seller
         notice of such matter within two (2) years after the Closing Date,
         except for (x) any breach of an agreement or covenant which, by its
         terms, is to be performed after the Closing Date, for which
         indemnification shall be required if the Indemnified Parties deliver
         notice at any time prior to expiration of the applicable period under
         the statute of limitations therefor, (y) any breach of a representation
         and warranty contained in the first sentence of Section 4.01, Section
         4.02 and Section 4.03, for which there shall be no time limitations in
         which the Indemnified Parties must deliver notice to Seller to be
         entitled to indemnification from Seller under Section 10.03(a), and (z)
         any breach of a representation and warranty of Seller set forth in
         Section 4.24, for which indemnification shall be required if the
         Indemnified Parties deliver notice of such matter prior to the
         expiration of the time period prescribed in Section 10.01.

                  (iv) Payments by Seller pursuant to Section 10.03(a) shall be
         limited to the amount of any Damage that remains after deducting
         therefrom any insurance proceeds and any indemnity, contribution or
         other similar payment recoverable by the Indemnified Parties from any
         third party with respect thereto; PROVIDED, HOWEVER, that the reduction
         for insurance proceeds shall itself be reduced by the present value of
         Purchaser's reasonably estimated increase in insurance costs directly
         attributable to the claim in respect of which such insurance proceeds
         shall have been received for the five years following the receipt of
         such proceeds using a discount rate of six percent.

                  (c) An Indemnified Party shall give Seller reasonably prompt
written notice of any claim, assertion, event or proceeding by or in respect of
a third party of which such Indemnified Party has knowledge concerning any
liability or damage as to which such Indemnified Party may request
indemnification hereunder. Failure to give such notice shall not waive any right
to indemnification on the part of the Indemnified Party or Parties who fail to
give such notice, except only to the extent of any damage or loss actually
suffered by Seller or any of its Affiliates by reason of the delay in receiving
such notice. Seller shall have the right to direct, through counsel of its own
choosing, provided such counsel is reasonably satisfactory to the Indemnified
Party, the defense or settlement of any such claim or proceeding at its own
expense, provided that Seller vigorously and diligently pursues such defense in
good faith and keeps the Indemnified Party and its attorneys reasonably informed
as to the progress of the defense and any proposed settlement. If Seller elects
to assume the defense of any such claim or proceeding, the Indemnified Party may
participate in such defense, but in such case the expenses of the

                                       62

<PAGE>


Indemnified Party shall be paid by the Indemnified Party. Notwithstanding the
foregoing, if an Indemnified Party determines in good faith that there is a
reasonable probability that any such claim or proceeding may adversely affect it
or its Affiliates other than as a result of monetary damages for which it or its
Affiliates would be entitled to indemnification under this Agreement, such
Indemnified Party may, by notice to Seller, assume the exclusive right to
defend, compromise, or settle such claim or proceeding, but Seller will not be
bound by any determination of such claim or proceeding so defended or any
compromise or settlement effected without its consent (which may not be
unreasonably withheld or delayed). The Indemnified Party shall provide Seller
with access to such Indemnified Party's records and personnel relating to any
such claim, assertion, event or proceeding during normal business hours and
shall otherwise cooperate with Seller in the defense or settlement thereof, and
Seller shall reimburse the Indemnified Party for all the reasonable
out-of-pocket expenses of such Indemnified Party in connection therewith. If
Seller elects to direct the defense of any such claim or proceeding, the
Indemnified Party shall not pay, or permit to be paid, any part of any claim or
demand arising from such asserted liability (i) unless Seller consents in
writing to such payment, which consent will not be unreasonably withheld, or
(ii) unless Seller, subject to the last sentence of this Section 10.03(c),
withdraws from the defense of such asserted liability, or (iii) unless a final
judgment from which no appeal may be taken by or on behalf of Seller is entered
against the Indemnified Party for such liability or (iv) unless there is a
material risk if such asserted liability is not paid that an injunction or other
equitable relief will be granted which will have a Material Adverse Effect on
Purchaser or the Company or any of their Affiliates. Without the prior written
consent of the Indemnified Parties (such consent not to be unreasonably
withheld), Seller shall not enter into any settlement of any claim or
proceeding; PROVIDED HOWEVER, that , if pursuant to or as a result of such
settlement (x) injunctive or other equitable relief would be imposed against the
Indemnified Parties, or any of them, or (y) such settlement, in the reasonable
judgment of the Indemnified Parties, would have a Material Adverse Effect on
such Indemnified Parties or any Affiliate of such Indemnified Parties for which
it is not entitled to indemnification hereunder, or (z) such settlement does not
include a general release to all Indemnified Parties, then such settlement shall
require the prior written consent of the Indemnified Parties. If Seller shall
fail to defend any claim or proceeding that it has a duty to defend hereunder,
or if after commencing or undertaking any such defense, shall fail to diligently
prosecute and defend or withdraws from such defense, or if Seller cannot
reasonably defend the Indemnified Party due to conflicts of interest or
conflicts between the defense that it must assert on behalf of the Indemnified
Parties and the defense it must assert to protect its interests in such claim or
proceeding, the Indemnified Party shall have the right to undertake the defense
or settlement thereof, at Seller's expense. If the Indemnified Party assumes the
defense of any such claim or proceeding pursuant to this Section 10.03(c) which
Seller had the duty to defend hereunder, and proposes to settle such claim or
proceeding prior to a final judgment thereon or to forego any appeal with
respect thereto, then the Indemnified Party shall give Seller prompt written
notice thereof and Seller shall have the right to participate in the settlement
or assume or reassume the defense of such claim or proceeding subject to the
conditions set forth above; provided that if Seller does not assume or reassume
the defense within ten (10) Business Days or any earlier time that such offer to
settle expires, then the Indemnified Party can settle such claim in good faith
without the consent of

                                       63

Seller.

                  (d) Except as embodied and set forth in this Agreement, the
Disclosure Schedule, the certificates delivered pursuant to Article VIII or any
agreement executed and delivered pursuant to the provisions hereof, Seller has
not made, and is not making, any representation, warranty, covenant, promise or
agreement with respect to any matters contained herein or therein. Anything
herein to the contrary notwithstanding, no breach of any representation,
warranty, covenant or agreement contained herein or therein shall give rise to
any right on the part of the Indemnified Party, after the consummation of the
purchase and sale of the Shares contemplated by this Agreement, to rescind this
Agreement or any of the transactions contemplated hereby.

                  SECTION 10.04. CERTAIN LITIGATION.

                  (a) Notwithstanding anything in this Agreement to the
contrary, Seller shall assume the defense of, and all costs and expenses
associated with, including without limitation, the amount of any judgments or
settlements thereof, the matters set forth on Section 4.12 of the Disclosure
Schedule or any matters disclosed pursuant to Section 4.12, both before and
after the Closing Date. The Purchaser shall cause the Company to render such
assistance, information, documents and access to personnel and records as may be
reasonably requested by Seller in order to assist in such defense. Seller may
settle any such matters as they deem appropriate without Purchaser's consent as
long as (i) there is no finding or admission of any violation any applicable law
or regulation, or any violation of the rights of Purchaser and no effect on any
other claims that may be made against Purchaser or its Affiliates, (ii) the sole
relief provided under the settlement in monetary damages that are paid in full
by Seller and (iii) Purchaser will have no liability with respect to any
compromise or settlement of such claims effected without its consent. To the
extent that the Purchaser or the Company receives any insurance proceeds from
any insurance policy covering the Company which was in force prior to the
Closing with respect to any matters set forth on Section 4.12 of the Disclosure
Schedule, they shall as soon as reasonably practicable pay such insurance
proceeds to Seller. Further, Purchaser hereby assigns to Seller any rights with
respect to such insurance proceeds and/or any claims against insurance companies
with respect to matters set forth on Section 4.12 of the Disclosure Schedule.
Seller shall promptly reimburse Purchaser and/or the Company, as applicable, for
all out-of-pocket costs relating to assistance provided pursuant to this Section
10.04. The parties hereby agree that the limitations set forth in Section
10.03(b)(i) and (ii) shall not apply with respect to this Section 10.04(a).

                  (b) The parties hereby agree that, following the Closing,
Seller shall retain the right to continue and control prosecution, at Seller's
sole expense, of the lawsuit entitled PHYSICIAN CORPORATION OF AMERICA AND PCA
PROPERTY AND CASUALTY INSURANCE COMPANY V. INSURANCE INDUSTRY CONSULTANTS, INC.
WYNN, DEXTER & SAMPEY, P.A., WILLARD W. PEACOCK, GARY P. HOBART AND GARY R.
RESETAR, Case No. CI 97-4606, pending before the Circuit Court in and for Orange
County, Florida (the "MALPRACTICE ACTION") and to receive the proceeds of any

                                       64

<PAGE>


settlement or judgment arising from the Malpractice Action; PROVIDED, HOWEVER,
that Seller shall indemnify the Company and Purchaser against and hold them
harmless from, and shall pay all Damages arising directly or indirectly from or
in connection with, any claim asserted against the Company and/or Purchaser
related to the Malpractice Action on a dollar-for-dollar basis without regard to
any of the limitations set forth in Section 10.03(b)(i) and (ii).

                  (c) Seller and Purchaser hereby agree that, following the
Closing Date, they shall use their best efforts to cooperate and jointly control
the prosecution of the various applications presently pending before the Florida
Department of Labor and Employment Security ("DOLES") that seek refunds of
assessments paid by the Company and its various predecessors in interest from
and after 1996 to DOLES (The "DOLES APPLICATIONS"). Seller and Purchaser shall
share equally in the expense of prosecuting the DOLES Applications and in the
proceeds from refunds or settlements ultimately received thereon.

                                   ARTICLE XI

                        TERMINATION, AMENDMENT AND WAIVER

                  SECTION 11.01. TERMINATION. This Agreement may be terminated
at any time prior to the Closing:

                  (a) by the mutual written consent of Seller and Purchaser;

                  (b) by written notice by either Seller or Purchaser if the
Closing shall not have occurred prior to July 31, 2000; PROVIDED, HOWEVER, that
the right to terminate this Agreement under this Section 11.01(b) shall not be
available to any party whose failure to fulfill any obligation under this
Agreement shall have been the cause of, or shall have resulted in, the failure
of the Closing to occur prior to such date;

                  (c) by Purchaser, if Seller shall have breached or failed in
any material respect to perform or comply with any of its representations,
warranties, covenants or other agreements contained in this Agreement, which
breach or failure to perform or comply (A) would give rise to the failure of a
condition set forth in Section 9.02, and (B) is incapable of being cured by
Seller; or

                  (d) by Seller, if Purchaser shall have breached or failed in
any material respect to perform or comply with any of its representations,
warranties, covenants or other agreements contained in this Agreement, which
breach or failure to perform or comply (A) would give rise to the failure of a
condition set forth in Section 9.01, and (B) is incapable of being cured by
Purchaser.

                  SECTION 11.02. EFFECT OF TERMINATION. In the event of
termination of this Agreement as provided in Section 11.01, this Agreement shall
forthwith become void and there shall be no liability on the part of any party
hereto, except that (a) the obligations under Section 12.01 and the obligations
of the parties under the Confidentiality Agreement between Humana and Purchaser
dated November 4, 1999 (the "Confidentiality Agreement") will survive and (b)
nothing herein shall relieve either party from liability for any breach hereof.

                  SECTION 11.03. WAIVER. At any time prior to the Closing,
either party hereto may (a) extend the time for the performance of any of the
obligations or other acts of the other party hereto, (b) waive any inaccuracies
in the representations and warranties contained herein or in any document
delivered pursuant hereto or (c) waive compliance with any of the agreements or
conditions contained herein. Any such extension or waiver shall be valid only if
set forth in an instrument in writing signed by the party to be bound thereby.

                                   ARTICLE XII

                               GUARANTY OF HUMANA

                  Humana hereby unconditionally and irrevocably guarantees the
performance of Seller's obligations, responsibilities, duties and liabilities
under this Agreement. If Seller fails for any reason to satisfy said
obligations, responsibilities, duties or liabilities, Humana shall satisfy all
said obligations, responsibilities, duties and liabilities. This Guaranty
constitutes a guaranty of performance and payment when due and not of collection
and is not conditional or contingent upon any attempt to obtain performance by
or to collect from, or pursue or exhaust any rights or remedies against, Seller.


                                  ARTICLE XIII

amended or modified except by an instrument in writing signed by Seller, Humana
and Purchaser. Waiver of any term or condition of this Agreement shall only be
effective if in writing and shall not be construed as a waiver of any subsequent
breach or waiver of the same term or condition, or a waiver of any other term or
condition of this Agreement. Any failure or delay on the part of any party in
exercising any power or right hereunder shall not operate as a waiver thereof,
nor shall any single or partial exercise of any such right or power preclude any
other or further exercise thereof or the exercise of any other right or power
hereunder.
