                 such Employee Benefit Plan which is an Employee Welfare
                 Benefit Plan.

                          (D) Each such Employee Benefit Plan which is an

                 "qualified plan" under Code Sec. 401(a) and has received,
                 within the last two years, a favorable determination letter
                 from the Internal Revenue Service.

                 Employee Benefit Plan which is an Employee Pension Benefit
                 Plan (other than any Multiemployer Plan) equals or exceeds the
                 present value of all vested and nonvested Liabilities
                 thereunder determined in accordance with PBGC methods,
                 factors, and assumptions applicable to an Employee Pension
                 Benefit Plan terminating on the date for determination.

                 (ii) With respect to each Employee Benefit Plan that the
         Corporation maintains or ever has maintained or to which it
         contributes, ever has contributed, or ever has been required to

                 subject of a Reportable Event as to which notices would be
                 required to be filed with the PBGC. No proceeding by the PBGC
                 to terminate any such Employee Pension Benefit Plan (other
                 than any Multiemployer Plan) has been instituted or
                 threatened.

                          (B) There have been no Prohibited Transactions with

                 of any such Employee Benefit Plan (other than routine claims
                 for benefits) is pending or threatened. Neither the Sellers
                 nor the directors and officers (and employees with
                 responsibility for employee benefits matters) of the
                 Corporation has any Knowledge of any Basis for any such

                 Sellers nor the directors and officers (and employees with
                 responsibility for employee benefits matters) of the

                 Liability) or under the Code with respect to any such Employee
                 Benefit Plan which is an Employee Pension Benefit Plan.

effect and have not been amended or otherwise modified, rescinded, revoked or
assigned and, to the best of the Sellers' Knowledge, no condition exists or
event has occurred which in itself or with the giving of notice or the lapse of
time or both would result in the suspension, revocation, impairment, forfeiture
or non-renewal of any such third party payor program. The Corporation is and,
after the execution and delivery hereof and of the Service Agreement, the Group
will be, in full compliance with the requirements of all such third party payor
programs applicable thereto.

         determining rights to any benefit or payment;

                 (iii) failing to disclose knowledge by a claimant of the
         occurrence of any event affecting the initial or continued right to

for participation of such governmental authority or third party payor, and
after reasonable and independent inquiry and due diligence and investigation,
the Corporation

         9. REMEDIES FOR BREACHES OF THIS AGREEMENT.

         (a) Survival of Representations and Warranties. All of the
representations and warranties of the Parties contained in this Agreement shall
survive the Closing hereunder (even if the damaged Party knew or had reason to
know of any misrepresentation or breach of warranty at the time of Closing) and
continue in full force and effect for a period of two (2) years thereafter
(subject to any applicable statutes of limitations); provided, however, that
with respect to Federal and state tax matters, such survival period shall be
equal to the statute of limitations (without regard to any extension by the
Purchaser following Closing) for assessment of additional taxes.

         (b) Indemnification Provisions for Benefit of the Parties. In the
event any Party breaches (or in the event any third party alleges facts that,
if true, would mean the Party has breached) any of such Party's
representations, warranties, and covenants contained herein and, provided that
the other Party (the "Indemnitee") makes a written claim for indemnification
against the breaching party (the "Indemnitor") pursuant to Section 9(c)(i)
below, then the Indemnitor (jointly and severally, if the Sellers are the
Indemnitors) agrees to indemnify the Indemnitee from and against the entirety
of any Adverse Consequences the Indemnitee may suffer through and after the
date of the claim for indemnification (including any Adverse Consequences the
Indemnitee may suffer after the end of any applicable survival period)
resulting from, arising out of, relating to, in the nature of, or caused by the
breach (or the alleged breach).  or otherwise; provided, however, that the
Indemitor's obligation to indemnify and hold the Indemnitee harmless pursuant
to this Section 9 shall only accrue if and to the extent that the aggregate
claim for indemnification by the Indemnitee hereunder, determined in the
exercise of good faith, shall exceed $100,000.00 (excluding any items otherwise
payable by Indemnitor pursuant to any other agreement between the Parties,
including the Service Agreement).

         (c) Matters Involving Third Parties.

                 (i) If any third party shall notify the Indemnitee with
         respect to any matter (a "Third Party Claim") which may give rise to a
         claim for indemnification under this Section 9, then the Indemnitee
         shall promptly notify the Indemnitor thereof in writing; provided,
         however, that no delay on the part of the Indemnitee in notifying the
         Indemnitor shall relieve the Indemnitor from any obligation hereunder
         unless (and then solely to the extent) the Indemnitor thereby is
         prejudiced.





                                        
   26





                 (ii) The Indemnitor will have the right to defend the
         Indemnitee against the Third Party Claim with counsel of its choice
         reasonably satisfactory to the Indemnitee so long as (A) it notifies
         the Indemnitee in writing within 15 days after the Indemnitee has
         given notice of the Third Party Claim that the Indemnitor will
         indemnify the Indemnitee from and against the entirety of any Adverse
         Consequences the Indemnitee may suffer resulting from, arising out of,
         relating to, in the nature of, or caused by the Third Party Claim, (B)
         the Indemnitor provides the Indemnitee with evidence acceptable to the
         Indemnitee that the Indemnitor will have the financial resources to
         defend against the Third Party Claim and fulfill its indemnification
         obligations hereunder, (C) settlement of, or an adverse judgment with
         respect to, the Third Party Claim is not, in the good faith judgment
         of the Indemnitee, likely to establish a precedential custom or
         practice adverse to the continuing business interests of the
         Indemnitee, and (D) the Indemnitor conducts the defense of the Third
         Party Claim actively and diligently.

                 (iii) So long as the Indemnitor is conducting the defense of
         the Third Party Claim in accordance with Section 9(c)(ii) above, (A)
         the Indemnitee may retain separate co-counsel at its sole cost and
         expense and participate in the defense of the Third Party Claim, (B)
         the Indemnitee will not consent to the entry of any judgment or enter
         into any settlement with respect to the Third Party Claim without the
         prior written consent of the Indemnitor (not to be withheld
         unreasonably), and (C) the Indemnitor will not consent to the entry of
         any judgment or enter into any settlement with respect to the Third
         Party Claim without the prior written consent of the Indemnitee, not
         to be unreasonably withheld.

                 (iv) In the event any of the conditions in Section 9(c)(ii)
         above is or becomes unsatisfied, however, (A) the Indemnitee may
         defend against, and consent to the entry of any judgment or enter into
         any settlement with respect to, the Third Party Claim in any manner it
         may deem appropriate (and the Indemnitee need not consult with, or
         obtain any consent from, the Indemnitor in connection therewith), (B)
         the Indemnitor will reimburse the Indemnitee promptly and periodically
         for the costs of defending against the Third Party Claim (including
         attorneys' fees and expenses), and (C) the Indemnitor will remain
         responsible for any Adverse Consequences the Indemnitee may suffer
         resulting from, arising out of, relating to, in the nature of, or
         caused by the Third Party Claim to the fullest extent provided in this
         Section 9.

         (d) Determination of Adverse Consequences. The Parties shall take into
account the time cost of money (using the Applicable Rate as the discount rate)
in determining Adverse Consequences for purposes of this Section 9. All
indemnification payments under this Section 9 shall be deemed adjustments to
the Purchase Price.

         (e) Recoupment Under the Note. In the event that the Purchaser shall
suffer Adverse Consequences for which indemnification pursuant to the foregoing
provisions shall be payable by the Sellers and the Sellers shall not make any
such indemnification payment within sixty (60) days after such indemnity amount
shall become payable, the Purchaser shall have the option of recouping all or
any part of any Adverse Consequences it may suffer by notifying the Sellers
that the Purchaser is offsetting the amount of such Adverse Consequences
against the principal amount outstanding under the Note. An offset pursuant to
this subsection shall affect the timing and amount of payments required under
the Note in the same manner as if the Purchaser had made a permitted prepayment
(without premium or penalty) thereunder.





                                        
   27





         (f) Other Indemnification Provisions. The foregoing indemnification
provisions are in addition to, and not in derogation of, any statutory,
equitable, or common law remedy any Party may have for breach of
representation, warranty, or covenant. The Sellers hereby agree that they will
not make any claim for indemnification against the Corporation by reason of the
fact that they were directors, officers, employees, or agents of the
Corporation or were serving at the request thereof as a partner, trustee,
director, officer, employee, or agent of another entity (whether such claim is
for judgments, damages, penalties, fines, costs, amounts paid in settlement,
losses, expenses, or otherwise and whether such claim is pursuant to any
statute, charter document, bylaw, agreement, or otherwise) with respect to any
action, suit, proceeding, complaint, claim, or demand brought by the Purchaser
against the Sellers (whether such action, suit, proceeding, complaint, claim,
or demand is pursuant to this Agreement, applicable law, or otherwise).

         10. TERMINATION.

         (a) Termination of Agreement. Certain of the Parties may terminate
this Agreement as provided below:

                 (i) the Purchaser and the Sellers may terminate this Agreement
         by mutual written consent at any time prior to the Closing;

                 (ii) the Purchaser may terminate this Agreement by giving
         written notice to the Sellers at any time prior to the Closing (A) in
         the event any of the Sellers has breached any material representation,
         warranty, or covenant contained in this Agreement in any material
         respect, the Purchaser has notified the Seller of the breach, and the
         breach has continued without cure for a period of 10 days after the
         notice of breach or (B) if the Closing shall not have occurred on or
         before October 1, 1996, by reason of the failure of any condition
         precedent under Section 7(a) hereof (unless the failure results
         primarily from the Purchaser itself breaching any representation,
         warranty, or covenant contained in this Agreement); and

                 (iii) the Sellers may terminate this Agreement by giving
         written notice to the Purchaser at any time prior to the Closing (A)
         in the event the Purchaser has breached any material representation,
         warranty, or covenant contained in this Agreement in any material
         respect, any of the Sellers has notified the Purchaser of the breach,
         and the breach has continued without cure for a period of 10 days
         after the notice of breach or (B) if the Closing shall not have
         occurred on or before November 1, 1996 by reason of the failure of any
         condition precedent under Section 7(b) hereof (unless the failure
         results primarily from any of the Sellers themselves breaching any
         representation, warranty, or covenant contained in this Agreement).

         (b) Effect of Termination. If any Party terminates this Agreement
pursuant to Section 10(a) above, all rights and obligations of the Parties
hereunder shall terminate without any Liability of any Party to any other Party
(except for any Liability of any Party then in breach).

         11. MISCELLANEOUS.

         (a) Press Releases and Public Announcements. No Party shall issue any
press release or make any public announcement relating to the subject matter of
this Agreement without the prior written approval of





                                        
   28





the Purchaser and the Seller; provided, however, that any Party may make any
public disclosure it believes in good faith is required by applicable law or
any listing or trading agreement concerning its publicly-traded securities (in
which case the disclosing Party will use its best efforts to advise the other
Parties prior to making the disclosure).

         (b) Arbitration of Disputes; Legal Fees. Any dispute arising under
this Stock Purchase Agreement shall be submitted by the parties to binding
arbitration pursuant to the Florida Uniform Arbitration Act, with any such
arbitration proceeding being conducted in accordance with the rules of the
American Arbitration Corporation. Any arbitration panel presiding over any
arbitration proceeding hereunder is hereby empowered to render a decision in
respect of such dispute, to award costs and expenses (including reasonable
attorney fees) as it shall deem equitable and to enter its award in any court
of competent jurisdiction. Each of the Parties submits to the jurisdiction of
any state or federal court sitting in Ft. Lauderdale, Broward County, Florida
for purposes of enforcement of any arbitration award hereunder. Each Party also
agrees not to bring any action or proceeding arising out of or relating to this
Agreement in any other court. Each of the Parties waives any defense of
inconvenient forum to the maintenance of any action or proceeding so brought
and waives any bond, surety, or other security that might be required of any
other Party with respect thereto.

rights or remedies upon any Person other than the Parties and their respective
successors and permitted assigns.

         (e) Entire Agreement. This Agreement (including the documents referred
to herein) constitutes the entire agreement among the Parties and supersedes

written approval of the Purchaser and the Seller; provided, however, that the
Purchaser may (i) assign any or all of its rights and interests hereunder to
one or more of its Affiliates and (ii) designate one or more of its Affiliates
to perform its obligations hereunder (in any or all of which cases the
Purchaser nonetheless shall remain responsible for the performance of all of
its obligations hereunder).

         (g) Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original but all of which
together will constitute one and the same instrument.

other means (including personal delivery, expedited courier, messenger service,

of Florida or any other jurisdiction) that would cause the application of the
laws of any jurisdiction other than the State of Florida.

         (k) Amendments and Waivers. No amendment of any provision of this
Agreement shall be valid unless the same shall be in writing and signed by the
Purchaser and the Sellers. No waiver by any Party of any default,
misrepresentation, or breach of warranty or covenant hereunder, whether

default, misrepresentation, or breach of warranty or covenant hereunder or
affect in any way any rights arising by virtue of any prior or subsequent such
occurrence.

         (l) Severability. Any term or provision of this Agreement that is

         (n) Construction. The Parties have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or

shall arise favoring or





                                        
   30





disfavoring any Party by virtue of the authorship of any of the provisions of
this Agreement. Any reference to any federal, state, local, or foreign statute
or law shall be deemed also to refer to all rules and regulations promulgated
thereunder, unless the context requires otherwise. The word "including" shall
mean including without limitation. The Parties intend that each representation,
warranty, and covenant contained herein shall have independent significance. If
any Party has breached any representation, warranty, or covenant contained
herein in any respect, the fact that there exists another representation,
warranty, or covenant relating to the same subject matter (regardless of the
relative levels of specificity) which the Party has not breached shall not
detract from or mitigate the fact that the Party is in breach of the first
representation, warranty, or covenant.

         (o) Incorporation of Exhibits and Schedules. The Exhibits and
Schedules identified in this Agreement are incorporated herein by reference and
made a part hereof.

         (p) Specific Performance. Each of the Parties acknowledges and agrees
that the other Parties would be damaged irreparably in the event any of the
provisions of this Agreement are not performed in accordance with their
specific terms or otherwise are breached. Accordingly, each of the Parties
agrees that the other Parties shall be entitled to an injunction or injunctions
to prevent breaches of the provisions of this Agreement and to enforce
specifically this Agreement and the terms and provisions hereof in any action
instituted in any court of the United States or any state thereof having
jurisdiction over the Parties and the matter, in addition to any other remedy
to which they may be entitled, at law or in equity.
