                                   __________


     FOR A SPECIAL MEETING OF STOCKHOLDERS TO BE HELD ON SEPTEMBER 8, 1997


     This Proxy Statement is furnished to stockholders of Physician 
Corporation of America, a Delaware corporation (the "Company"), in connection 
with the solicitation by the Board of Directors of the Company of proxies for 
use at the Special Meeting of Stockholders of the Company to be held at the 
time and place specified below and at any and all adjournments or 
postponements thereof (the "Special Meeting").

     The cost of soliciting proxies, including reasonable out-of-pocket 
expenses incurred by banks, brokerage houses, nominees and fiduciaries and 
other custodians in forwarding proxy material to beneficial owners, will be 
borne by the Company.  Directors, officers and regular employees of the 
Company may solicit proxies personally, by telephone, by facsimile, by 
telegraph or by other electronic means.  Such directors, officers and 
employees will receive no compensation for their solicitation services other 
than their regular fees or salaries.  The Company has retained Corporate 
Investor Communications, Inc. to solicit proxies.  The fees of such firm are 
expected to be approximately $5,000 plus out-of-pocket expenses.

     This Proxy Statement and the accompanying form of proxy are first being 
mailed to stockholders of the Company on or about August 8, 1997.

     DO NOT SEND YOUR STOCK CERTIFICATES WITH YOUR PROXY CARD.  THE PROCEDURE 
FOR THE EXCHANGE OF YOUR SHARES AFTER THE MERGER IS CONSUMMATED IS SET FORTH 
IN THIS PROXY STATEMENT.  SEE "THE MERGER-PAYMENT FOR SHARES".

     The Special Meeting will be held at the offices of the Company, located 
at 6101 Blue Lagoon Drive, Miami, Florida 33126, on Monday, September 8, 
1997, at 10:00 a.m., Miami time.

     The purpose of the Special Meeting is to consider and act upon a 
proposal to adopt the Agreement and Plan of Merger, dated as of June 2, 1997 
(the "Agreement"), among Humana Inc., a Delaware corporation ("Humana"), 
HUMNOV, Inc., a Delaware corporation and wholly owned subsidiary of Humana 
("Humana Sub"), and the Company, and to approve the merger described therein 
pursuant to which Humana Sub will be merged with and into the Company (the 
"Merger").  See "Information Concerning Humana and its Affiliates".  The 
Agreement (omitting the disclosure schedules thereto) is attached hereto as 
ANNEX A.  For a description of the principal terms of the Agreement, see "The 
Merger".

<PAGE>

     As a result of the Merger, at the time the Merger becomes effective (the 
"Effective Time"), (i) each share of Common Stock, $.01 par value per share, 
of the Company (the "Common Stock") then outstanding (except those shares of 
Common Stock as to which dissenters' rights, if any, shall have been properly 
exercised under Delaware law and shares of Common Stock held by Humana and 
its subsidiaries) will be converted into the right to receive $7.00 in cash 
without any action on the part of the holder thereof and (ii) the Company 
will become a wholly owned subsidiary of Humana.  See "The Merger--Conversion 
of Shares" and "The Merger-Dissenters' Rights".  If the Agreement is adopted 
and the Merger is approved by the Company's stockholders, subject to the 
satisfaction or waiver of the other conditions set forth in the Agreement, it 
is anticipated that the Merger will be consummated as promptly as practicable 
following such approval, although there can be no assurance that all such 
conditions will have been satisfied or waived by that time.  See "The 
Merger--Effective Time of the Merger, --Conversion of Shares and --Conditions 
to the Merger".

     YOUR BOARD OF DIRECTORS, AFTER CAREFUL CONSIDERATION, HAS UNANIMOUSLY 
APPROVED THE AGREEMENT AND DETERMINED THAT THE MERGER IS FAIR TO, AND IN THE 
BEST INTERESTS OF, THE STOCKHOLDERS OF THE COMPANY AND RECOMMENDS THAT YOU 
VOTE FOR ADOPTION OF THE AGREEMENT AND APPROVAL OF THE MERGER.  In reaching 
its determination, the Board of Directors considered, among other things, the 
opinion, dated June 2, 1997, of Bear, Stearns & Co. Inc. ("Bear Stearns"), 
the Company's financial advisor, to the effect that the Merger is fair, from 
a financial point of view, to the stockholders of the Company.  The opinion 
of Bear Stearns, dated as of the date of this Proxy Statement and 
substantially similar to its opinion dated June 2, 1997, is included as ANNEX 
B hereto and is incorporated herein by reference together with Bear Stearns' 
consent, which is included as ANNEX C hereto.  Stockholders are urged to read 
the opinion in its entirety for further information respecting the 
assumptions made, matters considered and limits of the review undertaken by 
Bear Stearns.  See "The Merger -- Reasons for the Merger; Recommendation of 
the Board of Directors and --Opinion of Bear, Stearns & Co. Inc."

REPRESENTATION NOT CONTAINED IN THIS PROXY STATEMENT OR THE DOCUMENTS 
INCORPORATED HEREIN BY REFERENCE IN CONNECTION WITH THE SOLICITATIONS MADE 
HEREBY AND, IF GIVEN OR MADE, SUCH INFORMATION OR REPRESENTATION SHOULD NOT

THEIR AFFILIATES.  THIS PROXY STATEMENT DOES NOT CONSTITUTE A SOLICITATION OF 
A PROXY IN ANY JURISDICTION IN WHICH, OR TO ANY PERSON TO WHOM, IT IS 
UNLAWFUL TO MAKE SUCH A SOLICITATION. THE DELIVERY OF THIS PROXY STATEMENT 
SHALL NOT CREATE ANY IMPLICATION THAT THERE HAS NOT BEEN ANY CHANGE IN THE 
INFORMATION SET FORTH HEREIN OR THE AFFAIRS OF THE COMPANY OR HUMANA SINCE 
THE DATE OF THIS PROXY STATEMENT.

                                   THE MERGER
                                       
Reasons for the Merger. . . . The Board of Directors has concluded that the
                              acquisition of the Company by Humana upon the
                              terms and subject to the conditions set forth in
                              the Agreement is fair to, and in the best
                              interests of, the Company's stockholders.  See
                              "The Merger--Reasons for the Merger;
                              Recommendation of the Board of Directors".

Opinion of Financial 
 Advisor. . . . . . . . . . . The Company retained Bear, Stearns & Co. Inc.
                              ("Bear Stearns") to act as its financial advisor
                              in connection with a possible business
                              combination.  On June 2, 1997, Bear Stearns
                              rendered to the Company its written opinion to the
                              effect that, as of such date and based upon and
                              subject to the factors, assumptions and
                              qualifications set forth therein, the Merger was
                              fair, from a financial point of view, to the
                              stockholders of the Company.  The opinion was
                              updated as of the date of this Proxy Statement. 
                              The full text of the Bear Stearns opinion dated
                              the date of this Proxy Statement, which sets forth
                              the assumptions made, the matters considered and
                              the limits of review undertaken by Bear Stearns,
                              is attached as ANNEX B to this Proxy Statement, is
                              incorporated herein by reference and should be
                              read in its entirety.  See "The Merger--Opinion of
                              Bear, Stearns & Co., Inc."

Effective Time of the 
 Merger . . . . . . . . . . . If the Agreement is adopted and the Merger is
                              approved by the stockholders of the Company at the
                              Special Meeting, the Merger is expected to become
                              effective as promptly as practicable thereafter,
                              subject to the satisfaction or waiver of the other
                              conditions to the Agreement.  See "The
                              Merger--Effective Time of the Merger and
                              --Conditions to the Merger".

Conversion of Shares and
 Surrender of Stock
 Certificates . . . . . . . . Each share of Common Stock outstanding at the time
                              (the "Effective Time") the Merger becomes
                              effective (except those shares of Common Stock as
                              to which dissenters' rights, if any, shall have
                              been properly exercised and those shares of Common
                              Stock held by Humana and its subsidiaries) will be
                              converted into the right to receive $7.00 in cash.
                              See "The Merger--Dissenters' Rights".  Promptly
                              after the Effective Time, a form letter of
                              transmittal and instructions will be mailed to
                              each person who was, immediately prior to the
                              Effective Time, a holder of record of issued and
                              outstanding shares of Common Stock for use in
                              surrendering his or her certificates representing
                              such shares of Common Stock.  DO NOT SEND IN YOUR
                              CERTIFICATES UNTIL YOU RECEIVE THE LETTER OF
                              TRANSMITTAL.

Stock Options . . . . . . . . All employee and director options for the purchase
                              of shares of Common Stock (the "Options") will be
                              canceled by the Company at the Effective Time. 
                              Holders of Options (whether or not exercisable at
                              the Effective Time) who are employees of the
                              Company at the Effective Time will be entitled to
                              receive a cash payment based upon a Black-Scholes
                              option pricing model specified in the Agreement if
                              they remain employees at the end of a specified
                              period (which varies from 6 months to 18 months
                              depending upon the employee) or if they are
                              terminated without cause or resign with cause
                              prior thereto.  Holders of Options who are no
                              longer employees at the Effective Time or who are
                              non-employee directors will be entitled to receive
                              an amount (if any) equal to the product of (i) the
                              amount by which $7.00 exceeds the exercise 

                                      -2-

                              price per share subject to the Option and (ii) 
                              the number of shares subject to the Option 
                              (whether or not such Option was exercisable at 
                              the Effective Time).  See "The Merger--Stock 
                              Options".

Conditions to the Merger. . . Consummation of the Merger is subject to certain
                              conditions, including the accuracy of
                              representations and warranties (except where an
                              inaccuracy would not have a material adverse
                              effect on the breaching party), the performance in
                              all material respects of certain agreements and
                              obligations contained in the Agreement, the filing
                              of certain governmental notices and reports, the
                              receipt of certain governmental regulatory
                              approvals or consents, the adoption of the
                              Agreement and approval of the Merger by the
                              stockholders of the Company and the absence of any
                              injunction or other order that prevents the
                              consummation of the transactions contemplated by
                              the Agreement.  See "The Merger--Conditions to the
                              Merger".

Dissenters' Rights  . . . . . Stockholders have the right, in lieu of 
                              receiving $7.00 in cash for their shares of 
                              Common Stock, to demand payment of the fair 
                              value for their shares of Common Stock if the 
                              Merger is consummated, provided such holders do 
                              not vote for adoption of the Agreement and 
                              approval of the Merger and certain procedures 
                              are followed (including the requirement that 
                              any stockholder wishing to exercise such right 
                              must deliver a written demand for appraisal to 
                              the Corporate Secretary of the Company before 
                              the vote is taken to adopt the Agreement and 
                              approve the Merger).  Failure by a stockholder 
                              to take any necessary steps may result in a 
                              termination or waiver of the dissenters' rights 
                              of such stockholder.  See "The 
                              Merger--Dissenters' Rights" and ANNEX D to this 
                              Proxy Statement.

Amendment . . . . . . . . . . The Agreement may be amended or modified at any
                              time by an instrument in writing executed by each
                              of Humana, Humana Sub and the Company.  However,
                              after the Merger is approved and the Agreement is
                              adopted by the stockholders of the Company, no
                              amendment to the Agreement that by law would
                              require the approval of the stockholders of the
                              Company may be made without such further approval.

Interests of Certain Persons
 in the Merger  . . . . . . . In considering the recommendation of the Board 
                              of Directors of the Company with respect to the 
                              Agreement and the Merger, stockholders should 
                              be aware that certain members of the management 
                              of the Company and the Board of Directors of 
                              the Company have certain interests in the 
                              Merger that are in addition to the interests of 
                              stockholders of the Company generally 
                              (including, without limitation, benefits of up 
                              to approximately $5 million in the aggregate 
                              that may be received by the executive officers 
                              of the Company under Salary Continuation 
                              Agreements, consulting or non-compete 
                              agreements and cancellation of stock options as 
                              provided for in the Agreement and the payment 
                              of up $250,000 to one non-employee director).  
                              See "The Merger--Stock Options" and "Interests 
                              of Certain Persons in the Merger".

Breakup Fee . . . . . . . . . Pursuant to the Agreement, the Company has agreed
                              to pay Humana $17 million in cash, plus documented
                              expenses not to exceed $1.5 million, if (x) a
                              person makes an Alternative Proposal (as defined
                              below) for the Company and thereafter either
                              (i) the Company

                              terminates the Agreement in accordance with its 
                              terms by reason of such Alternative Proposal or 
                              (ii) Humana or the Company terminates the 
                              Agreement by reason of the stockholders of the 
                              Company not adopting the Agreement and 
                              approving the Merger at the Special Meeting or 
                              (y) Humana terminates the Agreement by reason 
                              of the Board having withdrawn or modified in a 
                              manner adverse to Humana its approval or 
                              recommendation of the Agreement or the Merger 
                              or recommending an Alternative Proposal to the 
                              Company's stockholders.  In addition, if the 
                              Agreement is terminated for any other reason 
                              (other than by reason of a breach of the 
                              representations and warranties of Humana or 
                              Humana Sub or the failure of Humana or Humana 
                              Sub to comply with their obligations under the 
                              Agreement) and within 12 months thereafter any 
                              Alternative Proposal is consummated, the 
                              Company has agreed to pay Humana the lesser of 
                              (i) $17 million or (ii) 3.5% of the aggregate 
                              value of the other business combination, plus 
                              documented out-of-pocket expenses incurred by 
                              Humana in connection with the Agreement not to 
                              exceed $1.5 million.  An "Alternative Proposal" 
                              is defined in the Agreement as any merger, 
                              acquisition, consolidation or similar 
                              transaction involving, or any purchase of all 
                              or any significant portion of the assets or any 
                              equity securities of, the Company or any of its 
                              Subsidiaries.  See "The Merger--Breakup Fee".

P&C Arrangement . . . . . . . On February 25, 1997, the Florida Department of
                              Insurance (the "Florida Department") instituted
                              receivership proceedings with respect to PCA
                              Property & Casualty Insurance Company, a
                              subsidiary of the Company ("P&C"), due to its
                              deficit as of December 31, 1996, of approximately
                              $121 million under generally accepted accounting
                              principles.  In connection with the execution of
                              the Agreement, the Company, P&C and PCA Solutions,
                              Inc., a wholly owned subsidiary of the Company,
                              entered into four interrelated agreements with
                              Centre Reinsurance Company of New York and an
                              affiliate related to reinsurance, claims run-off
                              administration and investment management. 
                              Concurrently, Humana deposited $15 million in an
                              escrow account for the benefit of P&C (which
                              deposit is required be returned to Humana except
                              if the Merger is not consummated under certain
                              specified circumstances).  Based on the foregoing,
                              the Florida Department agreed not to proceed with
                              receivership proceedings provided certain
                              conditions are met and the Merger occurs no later
                              than October 31, 1997.  See "The Merger--P&C
                              Arrangement".

The Humana Option . . . . . . In consideration for depositing $15 million in an
                              escrow account for the benefit of P&C, the Company
                              granted Humana an option to purchase for $0.01 per
                              share a number of shares of Common Stock equal to
                              $15 million divided by 70% of the average closing
                              prices of the Common Stock for the five trading
                              days immediately prior to the exercise of the
                              option.  The Company has the right to cancel the
                              option at any time by paying Humana $15 million
                              plus interest from the date of the deposit.  See
                              "The Merger--The Humana Option".

Termination . . . . . . . . . The Agreement may be terminated at any time prior
                              to the closing of the transactions contemplated
                              thereby by mutual consent of the Company and
                              Humana, or by either the Company or Humana if the
                              Merger shall not have been consummated by October
                              31, 1997, or if the stockholders of the Company do
                              not adopt the Agreement and approve the Merger at
                              the Special Meeting.  Either the Company or Humana
                              may terminate the Agreement if the other has
                              materially breached a representation,

                              warranty or covenant contained in the Agreement 
                              and such breach is not cured after notice.  In 
                              addition, the Company may terminate the 
                              Agreement if a third party makes a business 
                              combination proposal which is a "Superior 
                              Proposal" (as defined in "The 
                              Merger--Termination"), the Board determines in 
                              good faith after consultation with its outside 
                              counsel that the failure to approve such offer 
                              would not be consistent with the Board's 
                              fiduciary duties to stockholders and Humana is 
                              given five business days to modify the 
                              Agreement so that the other proposal would no 
                              longer constitute a Superior Proposal.  Humana 
                              may also terminate the Agreement if the Board 
                              shall have withdrawn or modified in a manner 
                              adverse to Humana its approval or 
                              recommendation of the Agreement or the Merger 
                              or shall have recommended an Alternative 
                              Proposal to the stockholders.  See "The 
                              Merger--Termination".

Certain Federal Income Tax
 Considerations . . . . . . . The receipt of cash for shares of Common Stock
                              pursuant to the Merger (including pursuant to the
                              exercise of dissenters' rights) will be a taxable
                              transaction for federal income tax purposes and
                              may also be a taxable transaction under applicable
                              foreign, state, local and other income tax laws. 
                              ALL STOCKHOLDERS SHOULD CAREFULLY READ THE
                              DISCUSSION UNDER "THE MERGER--CERTAIN FEDERAL
                              INCOME TAX CONSIDERATIONS".

Regulatory Approvals  . . . . The consummation of the Merger is subject to,
                              among other approvals, the prior approval of the
                              Florida Department, the Texas Department of
                              Insurance and the Office of the Commissioner of
                              Insurance of Puerto Rico, and the applicable
                              Medicaid governmental departments in Florida,
                              Texas and Puerto Rico.  The expiration of the
                              waiting period under the Hart-Scott-Rodino
                              Antitrust Improvements Act of 1976, as amended,
                              has occurred.  See "The Merger--Regulatory
                              Approvals".

                               VOTING AND PROXIES
                                       
RECORD DATE; VOTING AT THE SPECIAL MEETING; REQUIRED VOTE

     The Company has fixed July 25, 1997 as the record date (the "Record 
Date") for the determination of the holders of Common Stock entitled to 
notice of and to vote at the Special Meeting.  Accordingly, only holders of 
record of Common Stock on the Record Date will be entitled to notice of and 
to vote at the Special Meeting.  As of the Record Date, there were 38,839,791 
shares of Common Stock outstanding and entitled to vote, which shares were 
held in the aggregate by approximately 350 holders of record.  Each holder of 
record of Common Stock on the Record Date is entitled to cast one vote per 
share of Common Stock on all matters properly submitted for the vote of the 
Company's stockholders, exercisable in person or by properly executed proxy, 
at the Special Meeting. The presence, in person or by properly executed 
proxy, of the holders of a majority of the outstanding shares of Common Stock 
entitled to vote at the Special Meeting is necessary to constitute a quorum 
at the Special Meeting.

     The adoption of the Agreement and approval of the Merger by the 
stockholders of the Company will require the affirmative vote of the holders 
of a majority of the outstanding shares of Common Stock entitled to vote 
thereon. The affirmative vote of a majority of the shares of Common Stock 
represented in person or by a properly executed proxy would be required to 
approve any proposal to adjourn the Special Meeting to another time and/or 
place for the purpose of soliciting additional proxies in the event that 
there are not sufficient votes at the time of the Special Meeting to adopt 
the Agreement and approve the Merger (the "Adjournment Proposal").  If an 
executed proxy card is returned and the stockholder has abstained from voting 
on any matter, the shares represented by such proxy will be considered 
present at the meeting for purposes of determining a quorum but will not be 
considered present for purposes of calculating the vote.  If an executed 
proxy card is returned by a broker holding shares of Common Stock in street 
name that indicates that the broker does not have discretionary authority as 
to certain shares to vote on the Agreement, such shares will be considered 
present at the meeting for purposes of determining a quorum and for purposes 
of calculating the vote, but will not be voted with respect to such matter.  
Accordingly, abstentions and "broker non-voters" will have the same effect as 
a vote against adoption of the Agreement and approval of the Merger.  
Abstention from voting on the Adjournment Proposal would have the practical 
effect of voting against the proposal since it is one less vote for approval. 
 Broker non-votes on the Adjournment Proposal would have no impact on that 
proposal since they are not considered "shares present" for voting purposes.

     As of the Record Date, the executive officers and directors of the 
Company beneficially owned 4,950,374 shares of Common Stock (approximately 
12.4% of the total outstanding Common Stock).  The directors and executive 
officers of the Company have advised the Company that they intend to vote the 
shares of Common Stock beneficially owned by them in favor of the adoption of 
the Agreement and the approval of the Merger.  As of the Record Date, Humana 
beneficially owned 1,043,000 shares of Common Stock.

VOTING AND REVOCATION OF PROXIES

     All shares of Common Stock represented at the Special Meeting by 
properly executed proxies received prior to or at the Special Meeting, and 
not revoked, will be voted at the Special Meeting in accordance with the 
instructions indicated on such proxies.  If no instructions are indicated, 
such proxies will be voted for adoption of the Agreement, approval of the 
Merger and approval of any Adjournment Proposal.

     Any proxy given pursuant to this solicitation may be revoked by the 
person giving it at any time before it is voted.  Proxies may be revoked by 
(i) filing with the Corporate Secretary of the Company, at or before the 
taking of the vote at the Special Meeting, a written notice of revocation 
bearing a later date than the proxy, (ii) duly executing a later-dated proxy 
relating to the same shares and delivering it before the taking of the vote 
at the Special Meeting or (iii) attending the Special Meeting and voting in 
person (although attendance at the Special Meeting does not in and of itself 
constitute a revocation of a proxy).  Any written notice of revocation or 
subsequent proxy should be sent so as to be delivered to Physician 
Corporation of America, 6101 Blue Lagoon Drive, Miami, Florida  33126, 
Attention:  Corporate Secretary, or hand-delivered to the Corporate Secretary 
of the Company at that address at or before the taking of the vote at the 
Special Meeting.

                                      -7-
<PAGE>

     If a quorum is not obtained or if fewer shares are likely to be voted 
for adoption of the Agreement and approval of the Merger than the number 
required for adoption and approval, the Special Meeting may be adjourned for 
the purpose of obtaining additional proxies or votes or for any other 
purposes, and, at any subsequent reconvening of the Special Meeting, all 
proxies will be voted in the same manner as such proxies would have been 
voted at the original convening of the meeting (except for any proxies which 
have theretofore effectively been revoked or withdrawn), notwithstanding that 
they may have been effectively voted on the same or any other matter prior to 
the adjournment.

ADJOURNMENT OF THE SPECIAL MEETING

     If there are not sufficient votes to adopt the Agreement and approve the 
Merger at the Special Meeting, such proposals could not be approved unless 
the Special Meeting were adjourned to permit further solicitation of proxies 
from the Company's stockholders.  Proxies that are being solicited by the 
Board grant the discretionary authority to vote for any such adjournment.  If 
it is necessary to adjourn the Special Meeting, no notice of the time and 
place of the adjourned meeting is required to be given to the Company's 
stockholders other than the announcement of such time and place at the 
Special Meeting.  The affirmative vote of at least a majority of the Common 
Stock present or represented, in person or by proxy, and voting at the 
Special Meeting is required to approve such adjournment, whether or not a 
quorum is present at the Special Meeting.  An adjournment of the Special 
Meeting may be necessary because the limited time between the mailing of the 
Proxy Statement and the Special Meeting may result in the lack of a quorum at 
the Special Meeting.  To obtain the requisite vote, it may be necessary to 
adjourn the Special Meeting to solicit additional proxies.

     If the Special Meeting is postponed or adjourned, at any subsequent 
reconvening of the Special Meeting, all proxies will be voted in the same 
manner as such proxies would have been voted at the original convening of the 
Special Meeting (except for any proxies that have theretofore effectively 
been revoked or withdrawn).

     At the date of this Proxy Statement, the Board of Directors of the 
Company (the "Board") is not aware of any matter that may come before the 
meeting, other than those described above.  If any other matter is properly 
presented to the meeting for action and the enclosed form of proxy is 
returned, the individuals named in the proxy shall have discretionary 
authority to vote such proxy on any such matter in accordance with their best 
judgment.

Physician Corporation of America individually, or Physician Corporation of 
America and its consolidated subsidiaries, as the context may require and

the part of the holders thereof, each outstanding share of Common Stock 
(except those shares of Common Stock as to which dissenters' rights of 
appraisal, if any, shall have been properly exercised under Delaware law and 
shares of Common Stock held by Humana and the subsidiaries) will be canceled 
and converted into and will represent the right to receive $7.00 in cash 
(without interest), (ii) the Company will cause each employee and director 
option to purchase shares of Common Stock (an "Option"), to be canceled and 
each Option (whether or not such Option was exercisable at the Effective 
Time) held by former employees at the Effective Time or non-employee 
directors will be converted into the right to receive an amount in cash equal 
to the product of (x) the amount by which $7.00 exceeds the exercise price 
per share subject to the Option and (y) the number of shares subject to the 
Option (provided that holders of options (whether or not exercisable at the 
Effective Time) who are employees of the Company at the Effective Time will 
be entitled to receive a cash payment based upon a Black-Scholes option

of a specified period (which varies from six months to 18 months depending on 
the employee) or if they are terminated without cause or resign with cause 
prior thereto, see "-- Stock Options") and (iii) the Company will become a 
wholly owned subsidiary of Humana.   See "The Merger--Effective Time of the 
Merger and --Conversion of Shares" for information concerning the procedures 
for submitting stock certificates and receiving cash.

BACKGROUND OF THE TRANSACTION

     During the third quarter of 1995, the Company's Florida Medicaid premium 
reimbursement rate decreased 18%.  Because Florida Medicaid health premiums 
represented approximately 26% of the Company's revenues, the premium rate 
decrease resulted in a material decrease in the Company's operating earnings. 
In addition, continued operating losses at the Company's HMO operations in 
Alabama and Georgia and higher than expected medical and administrative 
expenses at the Company's Florida HMO operations, due, in part, to the 
expansion of the Medicare product line, contributed to the Company's earnings 
decline.  For the three months ended September 30, 1995, the Company reported 
a net loss of $1.2 million compared to net income of $6.7 million for the 
three months ended June 30, 1995.  As a result of this earnings decrease, the 
Board directed the management of the Company to develop and implement a 
variety of cost cutting and profit enhancing measures.  The Board also 
consulted with Bear Stearns & Co. Inc., its financial advisor ("Bear 
Stearns"), regarding alternatives available to the Company to enhance 
stockholder value.  In October 1995, the Company formally retained Bear 
Stearns to act as its financial advisor in examining and potentially 
implementing various strategic alternatives to enhance stockholder value.  
During the course of Bear Stearns' engagement, the Board examined with Bear 
Stearns the following strategic alternatives: (i) a high yield debt offering, 
(ii) an investment by a financial investor, (iii) divestitures and/or asset 
sales, (iv) an initial public offering by a subsidiary, (v) a leveraged 
buyout, (vi) a leveraged recapitalization, (vii) a sale of the Company and 
(viii) a merger of the Company.  The evaluation of alternatives to enhance 
stockholder value was undertaken continuously from October 1995 through the 
third quarter of 1996 at which time the Board decided to pursue a merger of 
the Company.  At that time, the Board determined that a merger of the Company 
would be in the best interests of the Company's stockholders, members, 
medical providers and employees.  For the three months and 12 months ended 
December 31, 

                                      -9-
<PAGE>

1995, the Company reported a net loss of $36.5 million and $24.6 million, 
respectively. Additionally, the Company incurred a $95.1 million net loss for 
the nine months ended September 30, 1996.

     In December 1995, the Board announced its intention to sell the 
Company's HMO plans in Alabama and Georgia primarily due to (i) continued 
operating losses at the plans, (ii) the high probability that neither state 
would implement a Medicaid managed care program in the foreseeable future, 
(iii) the decision by CHAMPUS to award its region 3 and 4 contract to Humana, 
thereby negating the Company's primary strategic reason for having HMO 
operations in these states and (iv) the need for cash by the Company to 
satisfy its debt obligations.  The Company requested Bear Stearns to assist 
it in undertaking an auction process to solicit interest from potential 
acquirors of the Alabama and Georgia HMO plans and, as a result of this 
process, sold the two HMO plans in September 1996 to Health Partners of 
Alabama, Inc. for approximately $23 million in cash and a three-year 
non-competition agreement for $1.5 million to be paid over a two year period. 
 As a result of the sale of the Alabama and Georgia HMOs, the Company was 
able to eliminate the operating losses from these HMOs subsequent to 
September 1996 and repay approximately $17 million of outstanding bank debt.

     In March 1996 the Board approved the sale of the Company's wholly-owned 
physician clinic operations located in Florida.  The Board, in conjunction 
with management, determined that the sale of the Company's clinic operations 
was in the best interests of the Company and its stockholders because of the 
following benefits that would result from the sale: (i) cash proceeds could 
be used to repay debt; (ii) the acquiror would most likely enter into a 
long-term medical services risk contract with the Company's Florida HMO 
operations at rates that were less than the Company's historical costs, 
thereby improving the Company's predictability of medical costs by 
transferring a substantial amount of underwriting risk associated with 
approximately 85,000 HMO members to a third party; and (iii) certain 
administrative costs could be reduced.  The sale of the Company's clinic 
operations was completed in June 1996 to FPA Medical Management, Inc. ("FPA") 
for approximately $24.0 million consisting of stock and warrants of FPA and a 
$15 million note that was paid in full in the third quarter of 1996.  As a 
result of the sale of the clinic operations, the Company was ultimately able 
to repay approximately $24.5 million of its outstanding bank debt.

     During the first quarter of 1996, the Company's Florida HMO operations 
began to demonstrate an improvement in earnings (through a reduction in 
operating losses), primarily resulting from the implementation of several 
cost cutting measures by management.  However, the rate of reduction in the 
Company's operating losses was not of the magnitude that would assure the 
Company's return to profitability prior to the Company becoming constrained 
by the financial covenants contained in the Company's credit facility.  As a 
result of this assessment, the Board directed management and Bear Stearns to 
continue the evaluation of strategic alternatives, including contacting 
potential strategic parties that may have an interest in merging with the 
Company, in order to enhance stockholder value.  The Board also instructed 
management to continue the implementation of the corrective measures 
identified previously.  During the first quarter of 1996, the Company, with 
the assistance of Bear Stearns, prepared and delivered informational 
documents to six entities, including Humana (collectively, the "1996 
Interested Parties") that the Company and Bear Stearns deemed to have a 
potential interest in a transaction with the Company.  The 1996 Interested 
Parties were engaged in the managed care industry and several had operations 
that were in the same state or contiguous to a state in which the Company had 
HMO operations.  The 1996 Interested Parties had entered into confidentiality 
agreements with the Company prior to receiving information from the Company.  
Senior management of the Company held meetings with several of the 1996 
Interested Parties at the Company's corporate offices as well as at the 
corporate offices of some of the 1996 Interested Parties.  These meetings and 
discussions were held through October 1996.

     In October 1996, Bear Stearns and management reviewed with the Board a 
list of other potential parties that they believed may have had an interest 
in merging with or acquiring the Company.  Following this review, the Board 
authorized Bear Stearns to contact these parties to determine their interest 
in a transaction with the Company.  On October 8, 1996, Sierra Health 
Services, Inc. ("Sierra") presented to the Company and Bear Stearns potential 
terms of a transaction with Sierra that would be subject to negotiation.  On 
October 16, 1996, representatives from Bear Stearns met with and informed the 
Board that of the 1996 Interested Parties, four parties were in late stages 
of their due diligence and that proposals for a transaction with the Company 
were to be communicated to Bear Stearns by 

                                      -10-
<PAGE>

October 23, 1996.  Except for Humana and Sierra, none of 1996 Interested 
Parties nor any of the parties that were contacted by Bear Stearns submitted 
a proposal by October 23, 1996, for a transaction with the Company.  Humana 
did not submit a formal proposal for a transaction with the Company, but 
instead communicated certain proposed terms regarding a potential transaction 
through certain representatives of senior management and its financial 
advisor.

     On October 23, 1996, the Board held a meeting with senior management of 
the Company and representatives of Bear Stearns and the Company's outside 
legal counsel to evaluate alternatives available to the Company to enhance 
stockholder value.  At this meeting, the Board was apprised by Bear Stearns 
of the conversations and meetings with parties that were potentially 
interested in a transaction with the Company, including the 1996 Interested 
Parties, and reviewed certain other strategic alternatives including an 
equity investment by a financial investor and selected divestitures.  The 
Board authorized management and Bear Stearns to continue discussions with 
those parties that had expressed an interest in a transaction with the 
Company.  On October 24, 1996, the managements of Sierra and the Company 
continued their due diligence reviews and their negotiations with respect to 
the terms, including the potential exchange ratio (the "Exchange Ratio") of 
Sierra's common stock for the Common Stock, on which a definitive agreement 
could be reached.  On October 29, 1996, the Company and Sierra reached an 
oral agreement on the terms of a transaction and agreed upon an Exchange 
Ratio of 0.45 (having a value of approximately $12.94 per share based upon 
the closing public market price of the Sierra common stock on October 29, 
1997 of $28.75).  On October 29, 1996, the closing public market prices for 
the Common Stock was $11.25.  On November 1, 1996, Sierra's Board of 
Directors held a meeting at which it approved the merger of a wholly owned 
subsidiary of Sierra with the Company.  On November 2, 1996, the Board held a 
meeting at which it received a report from management and a presentation by 
Bear Stearns, was advised by the Company's outside legal counsel and approved 
the merger with Sierra.  Based on the Exchange Ratio, the value of the 
transaction to the Company's stockholders was approximately $13.00 per share 
on November 2, 1996.  In addition, on November 2, 1996, the Company announced 
a third quarter pre-tax charge of $130 million related to a statutory claims 
reserve deficit at PCA Property and Casualty Insurance Company, a subsidiary 
of the Company ("P&C").

     On November 5, 1996, the Company received a written proposal from Humana 
to purchase all outstanding shares of the Common Stock for $10.75 per share 
in cash, subject to the negotiation of a mutually acceptable definitive 
purchase agreement.  The Common Stock had closed at $10.75 on November 4, 
1996.  On November 5, 1996, the Board held a special meeting to review the 
proposal received from Humana and, in consultation with Bear Stearns and the 
Company's outside legal counsel, unanimously determined to reject the 
proposal from Humana because (i) the proposed merger with Sierra held greater 
potential long-term benefits to the stockholders of the Company and (ii) the 
terms of the merger agreement with Sierra did not permit the Company to 
engage in any discussions or negotiations regarding an offer.

     During January and February 1997, the Company obtained certain requisite 
state and federal approvals for the Sierra merger and continued the year end 
audit of its 1996 financial statements.  In conjunction with this effort, in 
February 1997, the Company's independent actuaries completed a preliminary 
valuation of P&C's claims reserves as of December 31, 1996.  As a result of 
this valuation, after the close of the National Association of Securities 
Dealers, Inc. Automated Quotation System/National Market (the "Nasdaq 
National Market") on February 20, 1997 (on which date the Common Stock closed 
at $9.125), the Company announced that it anticipated recording an additional 
fourth quarter pre-tax charge of $80 million relating to P&C's claims.  On 
February 21, 1997, the Common Stock closed at $5.06.

     On February 21, 1997, Sierra announced its intention to re-evaluate its 
proposed merger with the Company.  On February 25, 1997, the Florida 
Department of Insurance for the State of Florida (the "Florida Department") 
obtained a court order requiring P&C to submit a plan by May 2, 1997, setting 
forth a program to show good cause why the Florida Department should not 
place P&C under statutory rehabilitation.  See "--P&C Arrangement".  On 
February 26, 1997, the Company announced that it estimated that the total 
1996 pre-tax charge related to P&C would be between $225 million and $250 
million.  On February 26, 1997, the Common Stock closed at $3.81.

                                      -11-
<PAGE>

     On March 1, 1997, Sierra and representatives of its financial advisor 
met with the Board and representatives of Bear Stearns and informed the Board 
that it would not proceed with the merger under its existing terms.  The 
value of the transaction to the Company's stockholders as of that date was 
approximately $11.87 per share based on the Exchange Ratio.  As an 
alternative proposal to the Board, Sierra offered to purchase the Company's 
Texas operations for $150 million in cash and $40 million in Sierra stock.  
Sierra also offered to enter into a management agreement to manage the 
Company and its subsidiaries and to manage the rehabilitation of P&C.  
Because the Board did not believe that the proposal provided any value to the 
Company's stockholders, it declined Sierra's proposal.  In subsequent public 
statements, Sierra has explained that it was unwilling to proceed with the 
merger under its existing terms because of the expected charges relating to 
P&C.

     On March 18, 1997, the Company filed suit against Sierra in the United 
States District Court for the Southern District of Florida.  In the suit, the 
Company alleges that Sierra terminated the Agreement and Plan of Merger among 
Sierra, Sierra Acquisition, Inc. and PCA (the "Sierra-PCA Merger Agreement") 
on March 1, 1997 and that the termination was not permitted by the terms of 
the Sierra-PCA Merger Agreement.  Alternatively, the Company alleges that 
Sierra's statement on March 1, 1997 that it would not proceed with the merger 
under its existing terms constituted a withdrawal or modification, or 
proposed withdrawal or modification, of the approval or recommendation of the 
Sierra-PCA Merger Agreement by the Sierra board of directors.  The Company 
also alleges that Sierra breached its covenants and agreements under the 
Sierra-PCA Merger Agreement by failing to take all reasonable action 
necessary or use all reasonable efforts to obtain approval of the merger by 
the Florida Department and the Florida Agency for Health Care Administration 
and by failing to offer employment to a key executive of the Company as 
required by the terms of the Sierra-PCA Merger Agreement.  The Company seeks 
liquidated damages in the amount of $20 million plus costs and expenses, 
pursuant to the terms of the Sierra-PCA Merger Agreement.  The Company also 
seeks additional actual damages for, among other things, loss of business 
opportunities, damage to business reputation, lost profits and other 
consequential damages allegedly caused by Sierra's breach of contract and 
fraudulent inducement to enter into the Sierra-PCA Merger Agreement.

     On March 27, 1997, Sierra and its wholly owned subsidiary filed suit 
against the Company in the Court of Chancery of the State of Delaware in and 
for New Castle County with respect to the failed merger.  In the suit, Sierra 
alleges that the Company's disclosures relating to P&C constitute a breach of 
the Company's representations and warranties under the Sierra-PCA Merger 
Agreement and that this breach entitled Sierra to terminate the Sierra-PCA 
Merger Agreement and to recover from the Company the sum of $3 million plus 
its expenses, as defined under the Sierra-PCA Merger Agreement.  Sierra also 
alleges that it is entitled to an award of damages resulting from allegedly 
false representations by the Company regarding its financial condition and 
the financial condition of its subsidiaries.  Sierra takes the position that 
it terminated the Sierra-PCA Merger Agreement in a letter to the Company 
dated March 18, 1997.

     Both lawsuits are still pending.  At this stage of the proceedings, it 
is impossible to predict with any degree of certainty whether the Company 
will prevail on the merits or the financial impact of the lawsuits on the 
Company. Management of the Company believes that these lawsuits will not 
impact the ability to consummate the Merger.

     Upon termination of the Sierra merger, the Company went into default of 
its $102.0 million Credit Facility, which triggered the following:  (i) a 
$1.0 million default fee, (ii) the interest rate was increased from prime 
plus 1% to a default rate of prime plus 4% and (iii) the entire principal 
balance became due upon demand.  The Credit Facility was renegotiated and on 
April 22, 1997, was modified as follows:  (i) the default was waived, (ii) a 
$1.0 million fee was paid, (iii) the interest rate became prime plus 3% 
increasing to prime plus 4% on August 1, 1997, (iv) the maturity date was 
extended to October 1, 1997, (v) the default rate was increased to prime plus 
9% and (vi) an additional $1.0 million fee would be payable if the Company 
did not have a refinancing commitment or definitive merger agreement that was 
satisfactory to the Credit Facility lenders in place before July 31, 1997.  
The Company believes that entering into the Agreement has satisfied the July 
31, 1997 requirement to pay the additional $1.0 million fee.

                                      -12-
<PAGE>

     On March 20, 1997, Sierra gave notice to the Company's Credit Facility 
lenders of its intent to demand payment from the Company of the $16.8 million 
loan that Sierra had advanced the Company in early 1997 (the "Sierra Loan"). 
Under the terms of the Sierra Loan, without the consent of the Company's 
Credit Facility lenders, Sierra cannot make demand for payment until 
September 20, 1997.  If the Sierra Loan is not paid when demanded, the 
interest rate increases from 8% to a default rate of 13%.

     The Company does not have the financial resources immediately available 
to repay the Sierra Loan or the Company's Credit Facility if demand were made.

     On March 24, 1997, George W. Vieth, Jr., Vice President - Development 
and Planning of Humana, another representative of Humana and a representative 
of its financial advisor, visited the Company at its offices in Miami to 
discuss a possible transaction between Humana and the Company.  Thereafter, 
between March 24, 1997, and April 15, 1997, Humana and the Company discussed 
amending the confidentiality agreement.  On March 31, 1997, the Company 
reported its net loss for the three and 12 months ended December 31, 1996, of 
$182.6 million and $277.7 million, respectively.

     In early April 1997, following the announcement by Sierra that it would 
not proceed with the merger with the Company, the Company and Bear Stearns 
prepared informational memorandums for dissemination to potential interested 
parties which included strategic parties as well as financial investors.  On 
April 15, 1997, Humana and the Company entered into an amended 
confidentiality agreement.  On April 16, 1997, the Company announced that it 
was in discussions with potential strategic and financial partners (on which 
date the Common Stock closed at $4.75).  The Board authorized Bear Stearns to 
commence discussions with parties that had expressed an interest in or it 
believed would have an interest in a transaction with the Company.  In 
addition, the Board directed Bear Stearns to hold discussions primarily with 
those parties that the Board believed could by May 2, 1997, enter into a 
definitive transaction agreement with the Company to provide for the 
elimination of the P&C statutory claims reserve deficit.  Discussions were 
held with seven entities, including Humana, (collectively, the "1997 
Interested Parties").  In addition, the Company retained Arthur Andersen LLP 
to solicit potential bank debt refinancing proposals.

     Subsequent to April 15, 1997, Humana conducted additional due diligence 
concerning the Company and several telephone conversations were held between 
representatives of Humana and the Company.  On April 24, 1997, Mr. David A. 
Jones, Chairman and Chief Executive Officer of Humana, and Mr. Vieth 
telephoned Dr. E. Stanley Kardatzke, Chairman of the Board and Chief 
Executive Officer of the Company, and Mr. Clifford W. Donnelly, Senior Vice 
President and Chief Financial Officer of the Company, to communicate Humana's 
interest in pursuing a transaction with the Company pursuant to which Humana 
would purchase all of the outstanding shares of common stock of the Company 
for $7.50 per share in cash, subject to negotiation of a mutually acceptable 
definitive transaction agreement.  The Common Stock had closed at $5.00 on 
April 23, 1997.  Based upon this proposal, the Board authorized 
representatives of senior management, Bear Stearns and the Company's outside 
legal counsel to conduct negotiations with representatives of Humana, its 
financial advisor and outside legal counsel, of a definite agreement.  These 
negotiations took place at the Company's corporate offices on May 3, 1997, 
and May 4, 1997.  The Company and Humana were not able to reach mutually 
acceptable terms during these discussions.

     On May 2, 1997, P&C entered into a Forbearance Agreement with the 
Florida Department in which P&C consented to the appointment of the Florida 
Department as receiver for purposes of rehabilitation or liquidation at any 
time on or after June 2, 1997, if the Florida Department had not approved an 
agreement, recapitalization or other transaction providing for the full and 
timely resolution of P&C's statutory claims reserve deficit.

     During May 1997, one of the other 1997 Interested Parties (the "Other 
1997 Interested Party") submitted three letters of interest proposing various 
possible structures of a transaction.  On May 7, 1997, Dr. Kardatzke was 
first contacted by the Other 1997 Interested Party's chief executive officer. 
 On May 14, 1997, the Other 1997 Interested Party conducted a preliminary 
on-site due diligence review of the Company.  A letter dated May 21, 1997, 
proposed the issuance of shares of Common Stock in exchange for the Other 
1997 Interested Party's HMO operations and 

                                      -13-
<PAGE>

$200.0 million in cash, with such new shares representing a majority of the 
outstanding shares of Common Stock.  Since only limited data was provided 
about the Other 1997 Interested Party's HMO operations and its value was 
never established, the proposal was rejected. This proposal included a 
related transaction whereby if the first transaction was not completed then 
the Company could sell a portion of its operations to the Other 1997 
Interested Party for $100.0 million in cash.  The May 26, 1997 letter 
proposed essentially the same terms as the May 21, 1997 letter, except that 
the related transaction was a $100.0 million loan maturing in one year with 
interest at prime plus 3%, if the first transaction was not completed. 
Inasmuch as both proposals with respect to the related transaction involved 
only $100.0 million, which amount was insufficient to meet the Company's cash 
requirements, and no consideration being paid to the Company's stockholders, 
the proposals were rejected.  On May 31, 1997, the Other 1997 Interested 
Party submitted a third proposal, which is discussed below.

     On May 16, 1997, Bear Stearns disseminated a letter to the 1997 
Interested Parties requesting binding written proposals for a transaction 
with the Company, including a mark-up of a draft definitive transaction 
agreement, by May 21, 1997.  On May 20, 1997, Humana submitted a draft merger 
agreement to the Company to purchase all of the shares of Common Stock at 
$6.50 per share in cash, subject to acceptance by May 30, 1997, which was 
later extended to June 2, 1997.  The Common Stock had closed at $5.625 on May 
19, 1997.  On or about May 21, 1997, the Company received written binding 
proposals from Humana and one of the other 1997 Interested Parties.  The 
binding proposal from the other 1997 Interested Party was to acquire $100.0 
million of the Company's 10% convertible preferred stock, which would convert 
into Common Stock at $3.50 per share, plus warrants.  The proposal was 
rejected since (i) the conversion price was only 50% of the Humana proposal, 
(ii) the $100.0 million was insufficient to meet the Company's cash 
requirements and (iii) the other 1997 Interested Party would obtain effective 
control of the Company with no consideration being paid to the Company's 
stockholders.  In addition, the Company received non-binding proposals for a 
transaction with the Company from the Other 1997 Interested Party and another 
one of the 1997 Interested Parties.  The non-binding proposal from the other 
1997 Interested Party was to acquire $100.0 million of the Company's 10% 
convertible debt, which would be converted into Common Stock at market value 
calculated as an average over an agreed upon time period.  This proposal was 
rejected since (i) it was subject to further exclusive due diligence, (ii) 
there was an uncertainty as to its closing, (iii) the $100.0 million was 
insufficient to meet the Company's cash requirements and (iv) the other 1997 
Interested Party would obtain effective control of the Company with no 
consideration being paid to the Company's stockholders.  Two of the 1997 
Interested Parties did not submit a proposal. In addition, the Company 
received a "highly confident letter" for a potential refinancing from a 
commercial bank.  Other than Humana's written proposal (which provided for 
the full and timely resolution of P&C's statutory claims reserve deficit), 
each of the written proposals provided for the funding of the reinsurance 
arrangement between Centre Reinsurance Company of New York ("Centre Re") and 
the Company.  See "--P&C Arrangement".

     On May 29, 1997, Dr. Kardatzke was informed by the chief executive 
officer of one of the 1997 Interested Parties that it was considering 
submitting a proposal to purchase all of the outstanding shares of the 
Company for $4.00 to $6.00 per share.  That party ultimately did not submit a 
proposal.

     On May 31, 1997, the Other 1997 Interested Party submitted a non-binding 
letter of intent to pursue a transaction which provided for a $150 million 
loan commitment by June 2, 1997 (subject to due diligence until June 2, 
1997), and proposed a merger transaction, but subject to due diligence which 
was to be completed by June 30, 1997.  The proposed merger would provide for 
a contingent value right ("CVR") which required the Company, in the future, 
to pay an annual special dividend for any shortfall in the average trading 
price of Common Stock in the first year below $8.00, in the second year below 
$9.00, and in the third year below $10.00 per share.  The Company did not 
consider the proposal submitted by the Other 1997 Interested Party to be 
superior to the Humana proposal pursuant to its definitive agreement with 
Humana because of: (i) the inability of the Company to assure its 
shareholders of a value superior to Humana's offer, (ii) the uncertainty of 
being able to structure a $150 million loan with the Company's commercial 
lenders and Sierra (although several discussions with the Company's 
commercial lenders took place) prior to June 2, 1997; (iii) the uncertainty 
of satisfactory completion of due diligence by both the Company and the Other 
1997 Interested Party and its impact upon the final terms of a definitive 
merger agreement and (iv) the uncertainty of whether the combined Company 
would have the financial ability to pay the CVR special dividend if necessary.

     The Company continued in its discussions with Humana with meetings 
commencing on May 30, 1997, and ending on June 2, 1997, at which meetings the 
terms of the Agreement were negotiated, including the $7.00 per share cash 
consideration.  On June 2, 1997, Humana and the Company negotiated certain 
agreements with the Florida Department.  Later that day, the Board 
unanimously determined that the Merger was fair to, and in the best interests 
of, the stockholders of the Company and approved and entered into the 
Agreement with Humana and the agreements with the Florida Department.  During 
this time the Common Stock closed at $7.125, $6.25 and $6.625 on May 30, June 
2 and June 3, 1997, respectively.

REASONS FOR THE MERGER; RECOMMENDATION OF THE BOARD OF DIRECTORS

     In approving the Merger, the Agreement and the other transactions 
contemplated thereby and in recommending that the Company's stockholders vote 
for adoption of the Agreement and approval of the Merger, the Board 
considered a number of factors in favor of its approval including:

          1.   the presentations and views expressed by management of the 
     Company (at the meetings of the Board held on May 27, 1997, May 30, 
     1997, June 1, 1997 and June 2, 1997, and at previous meetings of the 
     Board) regarding, among other things: (a) the proceedings of the Florida 
     Department; (b) the financial condition, results of operations, cash 
     flow, business and prospects of the Company, including prospects of the 
     Company if it remains independent; (c) the strategic alternatives 
     available to the Company; (d) the fact that in view of discussions held 
     with various parties, management of the Company believed that it was 
     unlikely any other party would propose an acquisition or strategic 
     business combination that, taken as a whole, would be more favorable to 
     the Company and its stockholders than the terms of the Agreement; (e) 
     the recommendation of adoption of the Agreement and approval of the 
     Merger by the management of the Company; and (f) the short-term nature 
     of the Company's bank indebtedness and the assumption thereof by Humana 
     upon consummation of the Merger by virtue thereof;

          2.   the presentation of Bear Stearns at the meetings of the Board 
     held on May 27, 1997, May 30, 1997 and June 1, 1997, and the opinion of 
     Bear Stearns, expressed orally at the June 2, 1997, meeting (and 
     subsequently confirmed in writing), to the effect that, as of June 2, 
     1997, the transactions contemplated by the Agreement are fair, from a 
     financial point of view, to the stockholders of the Company.  The full 
     text of the opinion of Bear Stearns, dated as of the date of this Proxy 
     Statement, which sets forth the assumptions made, matters considered and 
     limitations on the review undertaken by Bear Stearns is attached hereto 
     as ANNEX B.  Stockholders are urged to the read the opinion of Bear 
     Stearns carefully in its entirety for assumptions made, matters 
     considered and the limits of the review undertaken by Bear Stearns;

          3.   the extensive arms-length negotiations between the Company and 
     Humana, leading to the belief of the Board that $7.00 per share 
     represented the highest price per share that could be negotiated with 
     Humana;

          4.   the history of the Company's discussions with other parties, 
     including, without limitation, (a) the fair and ample opportunity 
     provided to the 1997 Interested Parties to submit proposals to the 
     Company, (b) that none of the other proposals contemplated the 
     acquisition of the Company for more than $7.00 per share in cash, (c) 
     that the noncash component of the other 1997 Interested Parties' 
     proposals would subject the stockholders of the Company to the risks and 
     uncertainties associated with equity securities, and (d) that following 
     repeated requests by the Company's financial advisors to the other 1997 
     Interested Parties and their financial advisors that the other 1997 
     Interested Parties submit their best and final proposals, the other 1997 
     Interested Parties elected not to amend or modify their proposals; 

          5.   the results of the inquiries made by the Company's management 
     and financial advisors to major companies in the managed health care and 
     related industries, regarding a possible strategic alliance, 
     partnership, business combination, acquisition or similar transaction 
     with the Company;

                                      -15-
<PAGE>

          6.   that, in the Agreement, Humana has agreed to honor all 
     employment and severance agreements and arrangements with respect to 
     employees and former employees of the Company;

          7.   other provisions of the Agreement, including the parties' 
     representations, warranties and covenants, the conditions to their 
     respective obligations and the inability of Humana to terminate the 
     Agreement for a material adverse change related to P&C or PCA Solutions, 
     Inc., a wholly owned subsidiary of the Company ("PCA Solutions"); 

          8.   the business reputation and capabilities of Humana and its 
     management, and Humana's financial strength, including its ability to 
     finance the Merger and to resolve the P&C statutory claims deficit;

          9.   the current and anticipated status of the managed health care 
     industry in the United States, including increasing competition, limited 
     pricing flexibility, anti-managed care legislative initiatives and the 
     continuing need for mass volume to obtain better health care costs and 
     to allow lower premiums and appropriate operating and profit margins;

          10.  the likelihood of continued consolidation in the managed 
     health care sector and the possibility that changes in the industry, 
     depending on their nature, could be disadvantageous to the Company as an 
     independent company;

          11.  that, following completion of the Merger, Humana has 
     sufficient financial resources to pay off the Company's Credit Facility 
     and the Sierra Loan, and to fund the P&C statutory deficit; and

          12.  that P&C had, in the May 2, 1997 Forbearance Agreement with 
     the Florida Department, consented to the Florida Department's 
     appointment any time on or after June 2, 1997, as receiver for P&C for 
     purposes of rehabilitation or liquidation, unless the Florida Department 
     was by then satisfied with the Company's plan for assuring full payment 
     for P&C's liabilities.  If so appointed, the Florida Department might 
     assert additional claims or demands against the Company and certain 
     subsidiaries or seek to hold the Company responsible for P&C's deficit.  
     On June 2, 1997 the Florida Department agreed to defer obtaining its 
     appointment as receiver in view of Humana's commitment made in the 
     Agreement and the other transactions described elsewhere herein under 
     "--P&C Arrangement".

     In addition, the Board also considered potential risks relating to the 
Merger, including the risk that the Merger would not be consummated, with the 
adverse effect that might have on the proceedings of the Florida Department 
and the Company's ability to repay its outstanding bank indebtedness.  The 
Board believed, however, that these risks were outweighed by the potential 
benefits to be realized from the Merger.

     The foregoing discussion of information and factors considered by the 
Board is not intended to be exhaustive.  In view of the variety of factors 
considered in connection with the evaluation of the Merger, the Board did not 
find it practicable to, and did not quantify or otherwise assign relative 
weights to, the specific facts considered in reaching its determination and 
recommendations.  In addition, individual members of the Board may have given 
different weights to different factors.

     THE BOARD BELIEVES THAT THE MERGER IS FAIR TO, AND IN THE BEST INTERESTS 
OF, THE COMPANY AND ITS STOCKHOLDERS, HAS UNANIMOUSLY APPROVED IT AND 
RECOMMENDS THAT THE COMPANY'S STOCKHOLDERS VOTE FOR ADOPTION OF THE AGREEMENT 
AND APPROVAL OF THE MERGER.

OPINION OF BEAR, STEARNS & CO. INC.

     The Board retained Bear Stearns as of March 19, 1997 to act as its 
financial advisor and to render an opinion to the Board as to the fairness of 
the Merger (the "Transaction"), from a financial point of view, to the 
stockholders of the Company.  Bear Stearns was retained based upon its 
qualifications, reputation and expertise with respect to mergers and 
acquisitions in the health care industry, as well as Bear Stearns' prior 
investment banking relationship and familiarity with the Company.  On June 2, 
1997, Bear Stearns rendered its written opinion to the Board to the effect 
that the Transaction was fair, from a financial point of view, to the 
stockholders of the Company as of such date.  Bear Stearns subsequently 
issued a substantially similar written opinion to the Board to the effect 
that the Transaction was fair, from a financial point of view, to the 
stockholders of the Company as of the date of this Proxy Statement.  No 
restrictions were imposed by the Board upon Bear Stearns with respect to any 
investigations made or procedures followed by Bear Stearns in rendering its 
opinions.

     THE FULL TEXT OF THE BEAR STEARNS' OPINION DATED AS OF THE DATE OF THIS 
PROXY STATEMENT IS ATTACHED AS ANNEX B TO THIS PROXY STATEMENT.  STOCKHOLDERS 
OF THE COMPANY ARE URGED TO, AND SHOULD, READ SUCH OPINION CAREFULLY AND IN 
ITS ENTIRETY IN CONJUNCTION WITH THIS PROXY STATEMENT FOR ASSUMPTIONS MADE, 
MATTERS CONSIDERED AND LIMITS OF THE REVIEW BY BEAR STEARNS.

     Bear Stearns' opinions address only the fairness of the Transaction, 
from a financial point of view, to the stockholders and does not constitute a 
recommendation to any stockholder as to how such stockholder should vote with 
respect to the adoption of the Agreement and approval of the Merger.

     Although Bear Stearns evaluated the financial terms of the Transaction 
and participated in discussions concerning the consideration to be paid, Bear 
Stearns did not recommend the specific consideration to be paid in the 
Transaction.  The consideration to be received by the stockholders as a 
result of the Transaction was determined by negotiations between the Company 
and Humana after consultation by each of such parties with their respective 
financial advisors.  In connection with rendering its opinions, Bear Stearns, 
among other things: (i) reviewed the Agreement; (ii) reviewed this Proxy 
Statement (only with respect to the opinion dated as of the date of this 
Proxy Statement); (iii) reviewed the Company's Annual Reports to Shareholders 
and Annual Reports on Form 10-K for the years ended December 31, 1994 through 
1996 and the Company's Quarterly Report on Form 10-Q for the period ended 
March 31, 1997; (iv) reviewed certain operating and financial information 
provided to Bear Stearns by the management of the Company relating to the 
Company's business and prospects, including financial projections as of May 
3, 1997, provided to Bear Stearns by management of the Company; (v) met with 
certain members of the senior management of the Company to discuss the 
Company's operations, historical financial statements, future prospects and 
financial condition; (vi) met with certain members of the Florida Department 
to discuss the regulatory implications of the financial status of P&C, 
including the possibility of having P&C placed into receivership; (vii) met 
with certain members of the senior management of the Company to discuss the 
impact on the Company of having P&C placed into receivership; (viii) visited 
the Company's facilities in Miami, Florida and Orlando, Florida; (ix) 
reviewed the historical stock prices, trading activity and valuation 
parameters of the Common Stock; (x) reviewed publicly available financial 
data, stock market performance data and valuation parameters of companies 
that Bear Stearns deemed generally comparable to the Company; (xi) reviewed 
the terms of recent mergers and acquisitions of companies that Bear Stearns 
deemed generally comparable to the Transaction; and (xii) considered and 
conducted such other studies, analyses, inquiries and investigations as Bear 
Stearns deemed appropriate.

     In the course of its review, Bear Stearns relied upon and assumed, 
without independent verification, the accuracy and completeness of all the 
financial, regulatory and other information provided to it by the Company and 
others. With respect to the projections provided to Bear Stearns by the 
Company, Bear Stearns determined not to rely solely on the internal estimates 
of the Company's future financial performance in its analyses because of, 
among other things, the inherent uncertainty of such projections and the fact 
that actual results for fiscal 1996 differed materially from past projections 
for such periods for the Company; with the Company's consent, Bear Stearns 
also considered consensus estimates of the Company's earnings per share for 
fiscal 1997 published by security analysts (other than those 

                                      -17-
<PAGE>

published by Bear Stearns' security analyst) as reported by Institutional 
Brokers Estimate System as of May 29, 1997.  Bear Stearns did not assume any 
responsibility for the information or projections provided to it and Bear 
Stearns further relied upon the assurances of the management of the Company 
that they are unaware of any facts that would make the information or 
projections provided to Bear Stearns incomplete or misleading. 

     Bear Stearns did not perform or obtain any appraisal of the assets or 
liabilities of the Company in connection with rendering its opinions, nor was 
it furnished with any such appraisals.  Bear Stearns' opinions do not address 
the Company's underlying decision to pursue the Transaction.  Bear Stearns' 
opinions are necessarily based on economic, market and other conditions in 
effect, and the information made available to Bear Stearns, as of the 
respective dates thereof.

     In connection with its opinions, Bear Stearns performed the following 
analyses: (i) a going concern value of the Company based upon an analysis of 
selected publicly-traded companies, (ii) a going concern value of the Company 
based upon an analysis of selected precedent transactions and (iii) a segment 
analysis of the Company.

     The following is a brief summary of certain of the financial analyses 
used by Bear Stearns in connection with rendering its opinions to the Board 
on June 2, 1997, and as of the date of this Proxy Statement.

     GOING CONCERN VALUE - ANALYSIS OF SELECTED PUBLICLY-TRADED COMPANIES. 
Bear Stearns reviewed and compared the financial and market performance of 
the Company to the financial and market performance of 14 publicly-traded 
companies engaged in the managed health care services industry that Bear 
Stearns believed were comparable in certain respects to the Company (the "HMO 
Companies").  The HMO Companies were: Coventry Corporation; Foundation Health 
Corporation; Healthsource, Inc.; Humana; Maxicare Health Plans, Inc.; Mid 
Atlantic Medical Services, Inc.; Oxford Health Plans, Inc.; PacifiCare Health 
Systems, Inc.; Physicians Health Services, Inc.; RightChoice Managed Care, 
Inc.; Sierra; United HealthCare Corp.; United Wisconsin Services, Inc. and 
WellPoint Health Networks, Inc.  The HMO Companies were chosen by Bear 
Stearns as companies that, based on publicly available data, possess general 
business, operations and financial characteristics representative of 
companies in the industry in which the Company operates, although Bear 
Stearns recognized that each of the HMO Companies is distinguishable from the 
Company in certain respects.

     For each of the HMO Companies, Bear Stearns examined certain publicly 
available financial data including net revenue; earnings before interest, 
taxes, depreciation and amortization ("EBITDA"); earnings before interest and 
taxes ("EBIT"); net income; earnings per share; profit and expense margins; 
growth rates and enrolled membership.  Bear Stearns also examined certain 
balance sheet items, published earnings forecasts and the trading performance 
of the common stock of each of the HMO Companies.  Bear Stearns calculated 
the ratios of the closing prices of each of the HMO Companies' common stock 
(as of May 29, 1997) in relation to their respective projected earnings per 
share and the ratios of the enterprise value (the total market value of the 
outstanding common stock plus the par value of total debt and medical claims 
payable less cash, cash equivalents and investments) of each of the HMO 
Companies in relation to their respective net revenues, EBITDA, EBIT and 
enrolled memberships as of December 31, 1996.  Bear Stearns performed an 
analysis that compared certain ratios for the HMO Companies that it deemed to 
be the most comparable to the Company, including Coventry Corporation; 
Maxicare Health Plans, Inc.; Mid Atlantic Medical Services, Inc.; PacifiCare 
Health Systems, Inc. and Sierra (collectively, the "Comparable Companies), 
with the comparable ratios for the Company based upon the purchase price per 
share of the Common Stock (the "Purchase Price").

     Bear Stearns' analysis indicated that the ratios of the stock prices of 
the Comparable Companies in relation to their respective projected earnings 
per share for the year ending December 31, 1997, ranged from 12.9x to 34.5x 
and had a harmonic mean of 16.1x and a median of 14.1x.  The ratios of the 
stock prices of the Comparable Companies in relation to their respective 
projected earnings per share for the year ending December 31, 1998, ranged 
from 10.7x to 20.8x and had a harmonic mean of 12.9x and a median of 11.5x.  
The ratios of the enterprise values of the Comparable Companies to their 
respective projected EBITDA for the year ending December 31, 1997, ranged 
from 

                                      -18-
<PAGE>

4.5x to 33.1x (excluding the results of Maxicare Health Plans, Inc., which 
Bear Stearns deemed to be not meaningful in its analysis) and had a harmonic 
mean of 6.6x and a median of 5.6x.  The ratios of the enterprise values of 
the Comparable Companies to their respective enrolled memberships as of 
December 31, 1996 ranged from $388 to $819 and had a harmonic mean of $541 
and a median of $602.

     Bear Stearns analyzed the Company's value by reviewing the HMO 
operations and P&C separately.  Valuation multiples for the Company 
throughout Bear Stearns' analysis reflect transaction values and operating 
results for the HMO operations only.

     Based upon the Purchase Price, (i) the aggregate equity value was 
approximately $295 million, (ii) the aggregate transaction value (defined as 
the aggregate equity value plus the par value of total debt) (the 
"Transaction Value") was approximately $427 million, (iii) the aggregate 
adjusted transaction value (defined as the aggregate equity value plus the 
par value of total debt plus the assumed cost associated with the liabilities 
of P&C) (the "Adjusted Transaction Value") was approximately $529 million, 
(iv) the ratios of the Purchase Price per share to the projected earnings per 
share based upon the conservative case financial projections prepared by the 
Company's management for its HMO operations only (the "HMO Earnings Per 
Share") for the years ending December 31, 1997 and 1998 were 18.9x and 6.2x, 
respectively, (v) the ratio of the Transaction Value to the projected EBITDA 
based upon the conservative case financial projections prepared by the 
Company's management for its HMO operations only (the "HMO EBITDA") for the 
year ending December 31, 1997, was 11.0x and (vi) the ratios of the 
Transaction Value to the Company's enrolled membership as of December 31, 
1996, and March 31, 1996, were $422 and $376, respectively.

     Bear Stearns noted, based upon its analysis, that (i) the ratio of the 
Purchase Price per share to the projected HMO Earnings Per Share for the 
Company for the year ending December 31, 1997, was greater than the harmonic 
mean and median of the comparable ratios for the Comparable Companies and 
(ii) the ratio of the Transaction Value to the projected HMO EBITDA for the 
Company for the year ending December 31, 1997, was greater than the mean and 
median ratios of the enterprise values of the Comparable Companies to their 
respective projected EBITDA for the year ending December 31, 1997.

     GOING CONCERN VALUE - ANALYSIS OF SELECTED PRECEDENT TRANSACTIONS.  Bear 
Stearns reviewed certain financial data and the purchase prices agreed to be 
paid in 38 merger and acquisition transactions completed (except as noted) in 
the managed health care services industry, and selected a subset of precedent 
transactions that it deemed to be the most comparable to the Transaction (the 
"Comparable Transactions").  The Comparable Transactions included the 
following transactions (target company / acquiring company): Healthsource, 
Inc./CIGNA Corporation (pending); Health Systems International, 
Inc./Foundation Health Corp.; FHP International Corp./PacifiCare Health 
Systems, Inc.; U.S. Healthcare, Inc./Aetna Life and Casualty Co.; HealthWise 
of America, Inc./United HealthCare Corp.; Emphesys Financial Group, 
Inc./Humana Inc.; CII Financial Group, Inc./Sierra and Health Systems 
International, Inc./WellPoint Health Networks Inc. (terminated).

     For each of the target companies involved in the Comparable 
Transactions, Bear Stearns reviewed certain publicly available financial 
data, including net revenue, EBITDA, EBIT, net income, earnings per share, 
profit and expense margins and enrolled membership.  Bear Stearns also 
examined certain balance sheet items and published earnings forecasts (when 
available) for each of the target companies involved in the Comparable 
Transactions.  Bear Stearns calculated the ratios of the purchase prices of 
each of the target companies in the Comparable Transactions in relation to 
their respective latest 12 months and projected net income (for the next 
calendar year based on securities analysts' estimates immediately prior to 
the announcement of such transactions) and the ratios of the transaction 
value (the total purchase price of the equity plus total debt at par value 
and medical claims payable less cash, cash equivalents and investments) of 
each of the target companies in relation to their respective EBITDA for the 
latest 12 months and most recent enrolled membership.

                                      -19-
<PAGE>

     Bear Stearns' analysis indicated that the ratios of the purchase prices 
of each of the target companies to their respective net incomes for the 
latest 12 months ranged from 6.5x to 48.3x and had a harmonic mean of 15.9x 
and a median of 22.3x.  The ratios of the purchase price of each of the 
target companies to their respective projected net income ranged from 9.3x to 
34.0x and had a harmonic mean of 15.9x and a median of 18.4x.  The ratios of 
the transaction value of each of the target companies to their respective 
EBITDA for the latest 12 months ranged from 2.9x to 19.6x and had a harmonic 
mean of 8.5x and a median of 12.1x.  The ratios of the transaction value of 
each of the target companies to their respective enrolled members (excluding 
the results of the U.S. Healthcare, Inc./Aetna Life and Casualty Co. 
transaction, which Bear Stearns deemed to be not meaningful in its analysis) 
ranged from $287 to $1,835 and had a harmonic mean of $808 and a median of 
$1,358. 

     Bear Stearns noted that beginning with the HealthWise of America, 
Inc./United HealthCare Corp. transaction announced in February 1996 and 
ending with the Health Systems International, Inc./Foundation Health Corp. 
transaction announced in October 1996, multiples of purchase price to 
projected net income in the Comparable Transactions were on a downward trend. 
 In its analysis, Bear Stearns noted that the multiples of purchase price to 
projected net income in the HealthWise of America, Inc./United HealthCare 
Corp.; U.S. Healthcare, Inc./Aetna Life and Casualty Co. (announced April 
1996); FHP International Corp./PacifiCare Health Systems, Inc. (announced 
August 1996) and Health Systems International, Inc./Foundation Health Corp. 
transactions were 26.1x, 18.1x, 22.2x and 11.0x, respectively.  Similarly, 
the transaction value per member in these same transactions (excluding the 
multiple of $4,340 per member for the U.S. Healthcare, Inc./Aetna Life and 
Casualty Co. transaction, which Bear Stearns deemed to be not meaningful in 
its analysis) were $1,835, $1,497 and $778 per member, respectively.  Bear 
Stearns believed that valuation levels in the HMO industry had been 
decreasing because HMO companies had been experiencing margin pressure due to 
a lack of increases in premium rates coupled with increasing medical costs.

     Bear Stearns noted, based upon its analysis, that (i) the ratio of the 
Purchase Price per share to the Company's projected HMO Earnings Per Share 
for the year ending December 31, 1997, was greater than the harmonic mean of 
the ratios of the purchase prices of each of the target companies in the 
Comparable Transactions to their respective net incomes for the latest 12 
months and (ii) the ratio of the Transaction Value to projected HMO EBITDA 
for the Company for the year ending December 31, 1997, was greater than the 
harmonic mean of the ratios of the transaction values of each of the target 
companies in the Comparable Transactions to their respective EBITDA for the 
latest 12 months.

     SEGMENT ANALYSIS.  Bear Stearns determined an implied per share equity 
valuation of the Company based upon individual segment valuations of the 
Texas, Florida and Puerto Rico HMO operations.  Each individual HMO operation 
was value based on the Company's (i) enrolled membership as of March 31, 
1997, (ii) projected net income (based upon the conservative case financial 
projections prepared by the Company's management) for the year ending 
December 31, 1998, and (iii) projected EBITDA (based upon the conservative 
case financial projections prepared by the Company's management) for the year 
ending December 31, 1997.  Using the relevant valuation multiples from the 
"Going Concern Value - Analysis of Selected Publicly Traded Companies" and 
the "Going Concern Value - Analysis of Selected Precedent Transactions" 
discussed above, Bear Stearns determined enterprise  values for each segment 
of the Company.  Earnings from P&C and PCA Solutions were not included in 
this segment valuation and were assumed to be used to pay down the deficit in 
the P&C business.

     Depending on Bear Stearns' view towards the quality of earnings and 
membership of the Texas, Florida and Puerto Rico HMO operations, Bear Stearns 
adjusted the aforementioned valuation multiples to reflect the difficult 
operating and regulatory environments particular to its service areas 
(particularly Florida) as well as its membership mix.  In addition, Bear 
Stearns applied a discount due to the inherent uncertainty of such 
projections and the fact that actual results for fiscal 1996 differed 
materially from past projections for such periods for the Company.  Bear 
Stearns then decreased the aggregate enterprise value for the estimated 
capitalized cost of corporate expenses, costs relating to P&C, total debt and 
health claims payable, and increased the aggregate enterprise value for cash 
and statutory deposits to determine an imputed equity value and imputed 
equity value per share for the Company.  

                                      -20-
<PAGE>

     Bear Stearns noted that the imputed equity value per share based on 
multiples of enrolled membership as of March 31, 1997, projected net income 
for the year ending December 31, 1997, and projected EBITDA for the year 
ending December 31, 1997, ranged from ($3.88) to $5.37 per share.  The high 
of this range represents a discount of (23.3%) to the Purchase Price.  Bear 
Stearns also noted that the low tax basis of these operations reduces any 
rationale to implement an individual sale of the Company's component HMOs.  
Any such sale would generally result in adverse tax consequences to the 
stockholders.

     The last paragraphs of the sections titled (i) "Going Concern Value 
- -Analysis of Selected Publicly Traded Companies", (ii) "Going Concern Value 
- -Analysis of Selected Precedent Transactions" and (iii) "Segment Analysis", 
each identify certain items that Bear Stearns noted in performing its 
analyses.  In rendering its opinions that the Transaction was fair, from a 
financial point of view, to the stockholders of the Company, Bear Stearns did 
not rely upon each individual analysis, but rather considered the results of 
the analyses as a whole.

     Based upon the analyses of the Company's going concern value and the 
analysis of the Company's component HMOs, Bear Stearns concluded that the 
Transaction was fair, from a financial point of view, to the stockholders of 
the Company.

     Bear Stearns also reviewed the historical market prices and trading 
volumes of the Common Stock and noted the following: (i) on May 22, 1997, one 
week prior to public announcement of the Transaction, the closing price of 
the Common Stock was $5.938 per share; (ii) during the period from May 30, 
1996, through May 29, 1997, the Common Stock traded in a range of $2.625 to 
$14.375 per share; and (iii) during the period from March 30, 1993 (the date 
on which the Common Stock commenced trading following the Company's initial 
public offering) through May 29, 1997, the Common Stock traded in a range of 
$2.625 to $30.00 per share.

     The consideration to be received by the Company's stockholders pursuant 
to the Merger was determined through negotiations between the Company and 
Humana. Bear Stearns provided advice to the Company during the course of such 
negotiations, but did not make a recommendation with respect to the amount of 
the consideration to be received by the Company's stockholders pursuant to 
the Merger.  Bear Stearns has consented to the use in this Proxy Statement of 
its opinion dated as of the date of this Proxy Statement.

     The preparation of a fairness opinion is a complex process and is not 
necessarily susceptible to partial analysis or summary description.  
Selecting portions of the analyses or of the summary set forth above, without 
considering the analysis as a whole, could create an incomplete view of the 
processes underlying Bear Stearns' opinions.  In arriving at its opinions, 
Bear Stearns considered the results of all the analyses it performed.  No 
company or transaction used in the above analyses as a comparison is 
completely comparable to the Company or the Transaction.  Such analyses were 
prepared by Bear Stearns solely for purposes of providing its opinions as to 
the fairness of the Transaction, from a financial point of view, to the 
stockholders of the Company and do not purport to be appraisals or 
necessarily indicate the prices at which businesses or securities actually 
may be sold.  Analyses based upon forecasts of future results are not 
necessarily indicative of actual future results, which may be significantly 
more or less favorable than those results suggested by such analyses.  
Because such analyses are inherently subject to uncertainty, based upon 
numerous events beyond the control of the parties or their respective 
advisors, none of the Company, Humana, Humana Sub, Bear Stearns or any other 
person assumes responsibility if future results are different from those 
suggested by such analyses.  As described above, Bear Stearns' opinion, dated 
as of June 2, 1997, and Bear Stearns' presentation to the Board were two of 
the many factors taken into consideration by the Board in making its 
determination to approve the Agreement.  The foregoing summary is an accurate 
summary of the material provisions of Bear Stearns' opinion, but does not 
purport to be a complete description of the analyses performed by Bear 
Stearns in connection with rendering its opinions and is qualified in its 
entirety by reference to the opinion of Bear Stearns, dated as of the date of 
this Proxy Statement, set forth in ANNEX B hereto.

     In the ordinary course of its business, Bear Stearns may actively trade 
the equity securities of the Company or Humana for its own accounts and for 
the accounts of its customers and, accordingly, may, at any time, hold a long 

                                      -21-
<PAGE>

or short position in such securities.  In addition to serving as the 
Company's financial advisor in connection with the Transaction, Bear Stearns 
served as financial advisor to the Company in connection with several 
divestitures in 1996 for which it received aggregate fees equal to $600,000.

     Pursuant to a letter agreement between the Company and Bear Stearns, 
dated March 19, 1997, the Company agreed to pay Bear Stearns a fee of 
$600,000 upon the rendering of its fairness opinion relating to the 
Transaction (the "Fairness Opinion Fee").  The Company also agreed to pay 
Bear Stearns a fee equal to 1.3% of the Adjusted Transaction Value, such fee 
being payable upon consummation of the Transaction, against which fee the 
Fairness Opinion Fee would be credited.  The Company also agreed to reimburse 
Bear Stearns for certain of its out-of-pocket expenses incurred while acting 
as financial advisor to the Board in the Transaction and to indemnify Bear 
Stearns and certain related persons against certain liabilities in connection 
with the engagement of Bear Stearns, including certain liabilities under 
federal securities laws.  

EFFECTIVE TIME OF THE MERGER

     As promptly as practicable after adoption of the Agreement and approval 
of the Merger by the stockholders of the Company and all other conditions to 
the consummation of the Merger are satisfied or waived, Humana and the 
Company will take such action as is necessary to cause a Certificate of 
Merger to be filed in accordance with the requirements of the General 
Corporation Law of the State of Delaware (the "DGCL").  The Effective Time 
will be upon the filing of the Certificate of Merger with the Secretary of 
State of the State of Delaware.  It is currently contemplated that if all 
applicable conditions have been satisfied or waived at the time the Company's 
stockholders adopt the Agreement and approve the Merger, the Effective Time 
will occur as soon as practicable on the day of the Special Meeting; however, 
there can be no assurance that all such conditions will have been satisfied 
or waived by that time and it is possible that the Effective Time will occur 
after the day of the Special Meeting.  See "--P&C Arrangement".  The 
Agreement may be terminated under certain circumstances as described in 
"--Termination."

CONVERSION OF SHARES

     As of the Effective Time, and without any action on the part of the 
holder thereof, each outstanding share of Common Stock (except those shares 
of Common Stock (i) as to which dissenters' rights of appraisal, if any, 
shall have been properly exercised under Delaware law and (ii) held by Humana 
or its subsidiaries) will be converted into the right to receive $7.00 in 
cash.  See "The Merger--Dissenters' Rights".  All shares of Common Stock held 
by Humana or any of its subsidiaries or by the Company as treasury shares 
shall be canceled, and each issued and outstanding share of Humana Sub shall 
be converted into a share of Common Stock of the Company, as the surviving 
corporation in the Merger.

                 DO NOT SEND IN YOUR CERTIFICATES AT THIS TIME.
                    YOU WILL RECEIVE A LETTER OF TRANSMITTAL
                  AND FURTHER INSTRUCTIONS PROMPTLY AFTER THE
                         EFFECTIVE TIME OF THE MERGER.
                                       
LOST CERTIFICATES

     In the event any certificate representing shares of Common Stock shall 
have been lost, stolen or destroyed, upon delivery to the Company of an 
affidavit of that fact by the person claiming such certificate to be lost, 
stolen or destroyed and the delivery of such other documents as the Company 
may reasonably request, the Payment Agent (as defined in "--Payment for 
Shares") shall deliver $7.00 per share in cash in respect of the shares of 
Common Stock represented by such lost, stolen or destroyed certificate.  The 
Company, as the surviving corporation of the Merger, may, as a condition 
precedent to the delivery thereof, require the owner of such lost, stolen or 
destroyed certificate to provide to the Company a bond in favor of the 
Company or such other security as the Company shall reasonably deem necessary.

STOCK OPTIONS

     Pursuant to the Agreement, the Company will cause all employee and 
director options for the purchase of shares of Common Stock (the "Options") 
to be canceled at the Effective Time.

     Employee holders of Options employed with the Company as of the 
Effective Time will be entitled to receive for each canceled Option (whether 
or not exercisable at the Effective Time) either if (a) the employee is 
employed by Humana or any of its subsidiaries (including the Company) at the 
end of a benefit period specified in a Salary Continuation Agreement between 
the Company and the employee of between six months and 18 months depending on 
the terms of the Salary Continuation Agreement to which the employee is a 
party (or, lacking such an agreement, at the end of six months) following the 
Effective Time or (b) the employee's employment is terminated without cause 
or the employee resigns with cause prior thereto (as such terms are defined 
in the Salary Continuation Agreements), an amount in cash equal to the value 
for each such option based on a Black-Scholes option pricing model as 
specified in the Salary Continuation Agreements.

     Holders of Options who are no longer employed by the Company at the 
Effective Time or who are non-employee directors of the Company will be 
entitled to receive an amount (if any) equal to the product of (i) the amount 
by which $7.00 exceeds the exercise price per share subject to the Option and 
(ii) the number of shares subject to the Option (whether or not such Option 
was exercisable at the Effective Time).

     Assuming all employees who hold Options remained employed at the 
Effective Time and become eligible to receive a cash payment for the canceled 
Options as set forth above, the Company estimates that the aggregate cash 
payments required to be made in respect of Options would be approximately $5 
million.

     As of the date hereof, each of the University of Miami and The Jackson 
Memorial Foundation hold options to purchase 500,000 shares of Common Stock 
at $20.75 per share.  Since under the terms of the option agreements the 
holders of these options would only be entitled to receive the difference 
between $7.00 per share of Common Stock (I.E., the per share consideration to 
be paid in the Merger) and the exercise price of $20.75 per share, these 
options will have no value after the Effective Time.

PAYMENT FOR SHARES

     At or before the Effective Time, Humana will deposit in immediately 
available funds with a paying agent (the "Payment Agent") an amount (the 
"Payment Fund") equal to the product of the number of shares of Common Stock 
issued and outstanding at the Effective Time multiplied by $7.00 (other than 
shares of Common Stock held by stockholders, if any, who properly exercise 
their dissenters' rights of appraisal under Delaware law and shares of Common 
Stock held by Humana and its subsidiaries).  See "Source of Funds".  The 
Payment Fund will not contain funds for the payment of the Options.  See 
"Stock Options".

     As provided in the Agreement, as soon as practicable after the Effective 
Time (but in no event more than five days thereafter), Humana will direct the 
Payment Agent to mail to each person who was, immediately prior to the 
Effective Time, a holder of record of issued and outstanding shares of Common 
Stock (other than holders who have properly demanded dissenters' rights of 
appraisal for their shares of Common Stock), a form letter of transmittal and 
instructions for use by such person in effecting the surrender of the 
certificates which formerly represented any of such shares of Common Stock 
for payment therefor.  Upon surrender to the Payment Agent of such 
certificates, together with such letter of transmittal, duly executed and 
completed in accordance with the instructions thereto, and such other 
customary documents as may be required pursuant to such instructions, the 
Payment Agent will promptly cause to be paid to the person entitled thereto 
the amount in cash to which such person is entitled.  NO INTEREST WILL BE 
PAID OR WILL ACCRUE ON THE CASH PAYABLE UPON THE SURRENDER OF ANY SUCH 
CERTIFICATE.  If payment is to be made to a person other than the registered 
holder of the certificate surrendered, it will be a condition of such payment 
that the certificate 

                                      -23-
<PAGE>

so surrendered be properly endorsed or otherwise in proper form for transfer 
and that the person requesting such payment pay any transfer or other taxes 
required by reason of the payment or establish to the satisfaction of the 
Paying Agent that such tax has been paid or is not applicable.  One year 
following the Effective Time, Humana will be entitled to the return to it of 
any funds (including any interest and dividends received with respect 
thereto) that have been made available to the Payment Agent and that have not 
been disbursed to holders of certificates representing shares of Common Stock 
outstanding immediately prior to the Effective Time, and such holders may 
thereafter look only to Humana (subject to applicable abandoned property, 
escheat or other similar laws) as general creditors for the cash to which 
they are entitled.

P&C ARRANGEMENT

     P&C, the Company's subsidiary Florida property and casualty insurer, has 
reported a deficit as of December 31, 1996, of approximately $121 million 
under generally accepted accounting principles.  This deficit resulted from 
losses incurred or assumed under excess insurance, reinsurance and 
indemnification contracts in favor of assessable workers' compensation self 
insurance funds and mutual insurers.

     The Florida Department has exerted increasing control over, and has 
initiated legal proceedings against, P&C because of its deteriorating 
financial condition.  In November 1996, P&C entered into an administrative 
consent order, pursuant to which P&C ceased writing and renewing insurance 
policies, subjected most of its business operations and decisions to review 
and approval by the Florida Department, and was required to submit a 
corrective plan satisfactory to the Florida Department.  In late February 
1997, the Florida Department brought judicial proceedings seeking its 
appointment as receiver for P&C for purposes of rehabilitation.  Several 
proposed corrective plans were submitted, but none were approved.

     Under a Forbearance Agreement entered into May 2, 1997 (the "Forbearance 
Agreement"), P&C consented to the Florida Department's appointment as 
receiver for purposes of rehabilitation or liquidation on or after June 2, 
1997.  The Florida Department allowed P&C until that date to submit a 
satisfactory plan assuring full payment of claims and in the interim obtained 
greater control over its affairs and access to its records.  Separately, the 
Florida Department requested that the Company and certain subsidiaries pay 
P&C amounts aggregating approximately $35 million and refused to permit P&C 
to pay substantial amounts due to affiliates.  The Company disputed these 
demands but agreed to inform the Florida Department of progress in 
negotiations intended to obtain reinsurance coverage for P&C and/or to pay 
for such coverage through a financing transaction or business combination as 
described elsewhere herein.

     In connection with execution of the Agreement, and after lengthy 
negotiations in which the Florida Department participated, on June 2, 1997, 
the Company, P&C and PCA Solutions entered into four interrelated agreements 
with Centre Re and an affiliate.  Under the Aggregate Excess of Loss 
Reinsurance Agreement (the "Reinsurance Agreement"), Centre Re agreed to pay 
up to $230 million to satisfy policyholder claims against P&C if P&C is not 
able to discharge all its liabilities from its own resources.  The Company 
agreed to pay or arrange for payment of certain other liabilities of P&C, to 
contribute $20.1 million to P&C for tax benefits realized and to purchase or 
guarantee the collection of specified assets.  In addition, upon entering 
into the Reinsurance Agreement, P&C paid to and received from various 
affiliates amounts agreed by the parties to be owing through March 31, 1997.  
Of the total premium of $84 million payable to Centre Re, $4 million has been 
paid with the balance due at closing of the Reinsurance Agreement, now 
expected to coincide with the Effective Time.  In the event the Company 
consummates the Reinsurance Agreement, the Company may receive an experience 
refund up to a maximum amount of $42 million.  If the balance of the premium 
is not paid or the Centre Re transaction is not closed by October 31, 1997, 
the Reinsurance Agreement and the three related agreements identified below 
will automatically terminate, and Centre Re will retain the $4 million 
premium already paid but the Company would not be liable for the remaining 
premiums.

     Under the Claims Run-Off Administration Services Agreement (the "Claims 
Agreement"), PCA Solutions will act as third party claims service 
administrator for purposes of handling the run-off of P&C's insurance 
liabilities.  The Claims Agreement, which supplements the prior Management 
Contract under which PCA Solutions serves as managing general agent for P&C, 
imposes additional duties on PCA Solutions and entitles Centre Re to 
participate 

                                      -25-
<PAGE>

in and direct employment, compensation and property acquisition decisions of 
PCA Solutions. The Company guaranteed PCA Solution's performance of its 
duties under the Claims Agreement.  PCA Solutions' compensation for its 
services will be deferred and paid only from any available funds of P&C 
remaining after the run-off, which will probably be more than five years from 
the date of this Proxy Statement.

     Under the Investment Management Agreement, Zurich Investment Management, 
Inc., an affiliate of Centre Re, will manage the investment portfolio of P&C, 
within agreed guidelines and constraints under the Florida Insurance Code, 
for fees based on the size of the portfolio.  Under the Tax Allocation and 
Escrow Agreement between the Company and P&C, the latter will receive the 
benefit of certain federal net operating loss carryforwards of up to $72 
million if and when realized in the future by its corporate affiliates due to 
its net operating losses and capital loss carryforwards. 

     If the Centre Re transaction is closed (whether or not in connection 
with the Merger), in addition to paying the balance of the reinsurance 
premium, the Company, P&C, and PCA Solutions are required to collateralize 
various of their obligations to Centre Re.  P&C must pledge all its assets to 
secure its obligations under the Reinsurance Agreement.  In addition, the 
Company must pledge $45 million of liquid investments and its stock in PCA 
Solutions, and PCA Solutions must pledge all of its assets, to secure (a) 
obligations of PCA Solutions under the Claims Agreement, (b) the Company's 
guaranty of PCA Solutions' performance under the Claims Agreement and (c) 
certain of the Company's obligations under the Reinsurance Agreement.  The 
Company expects to obtain the $45 million of liquid investments through the 
Merger (or another financing transaction or business combination).  Other 
collateral agreed to be pledged to Centre Re will be available only if the 
Company's present lenders release their security interests in connection with 
repayment of their loans or otherwise.

     The Reinsurance Agreement provides that either Centre Re or Humana may, 
by notice, prevent the Centre Re transactions from closing if the Merger is 
consummated.  However, under the Agreement, Humana must, from and after the 
Effective Time, (a) adhere to the Centre Re agreements, (b) eliminate P&C's 
statutory deficit by making a capital contribution in that amount and 
committing to make additional contributions as and when needed thereafter to 
eliminate any future statutory deficits (the "Recapitalization Alternative") 
or (c) enter into such other arrangements as the Florida Department deems 
acceptable in its sole discretion.  If Centre Re elects not to close the 
reinsurance transaction, Humana must comply with the alternatives set forth 
in clauses (b) or (c) above.  The Florida Department has indicated that 
Humana's Recapitalization Alternative is acceptable.  No other alternative 
arrangement has been proposed or is now anticipated.  Under the terms of the 
Reinsurance Agreement, the consent of Centre Re and the Florida Department 
may be required to consummate the Merger prior to September 22, 1997.

     Based on its evaluation of the Agreement and Centre Re agreements, on 
June 2, 1997, the Florida  Department entered into a Joint Report to the 
Court and Supplemental Agreement (the "Supplemental Agreement") with P&C.  In 
the Supplemental Agreement, the Florida Department determined that the 
Company had made sufficient progress toward fulfilling the conditions in the 
Forbearance Agreement to justify extending the period of forbearance from 
appointment of a receiver for P&C and to allow a reasonable period for the 
agreed upon transactions to close.  The Florida Department agreed not to seek 
its appointment as receiver so long as certain conditions are being met, 
including: payment of amounts due to P&C's creditors, the absence of an event 
of default, absence of a material adverse change in the financial condition 
of P&C, PCA Solutions and Centre Re, and diligent pursuit of regulatory 
approvals required to close the Merger by October 31, 1997.  The Florida 
Department reserved the right to obtain its appointment as receiver for P&C 
in the event of, among other circumstances, noncompliance with or material 
misrepresentation in provisions of the Supplemental Agreement, denial of a 
regulatory consent or approval requisite to closing of the Merger, and 
failure to close the Merger by October 31, 1997.  The Company agreed to 
cooperate in the Florida Department's investigation of the assessable 
workers' compensation business and to keep the Florida Department regularly 
informed of progress in obtaining consents necessary to consummate the 
Merger.  P&C continues under the Florida Department's administrative 
supervision, and the receivership petition remains pending.

                                      -26-
<PAGE>

     The Supplemental Agreement also provides that, if the Florida Department 
does not enforce the Forbearance Agreement by obtaining its appointment as 
receiver or otherwise, and if the Merger is consummated, the receivership 
proceeding respecting P&C will be dismissed or abated and the parties will 
enter into a new administrative consent order.  That new order is to provide, 
among other things, for continued administrative supervision of P&C at least 
through 1998 under somewhat less stringent Florida Department control, 
suspension of P&C's certificate of authority (so that it could not resume 
active insurance operations unless its certificate were reinstated), and 
covenants that would protect the Company and its affiliates against the 
assertion of certain claims based on matters predating March 31, 1997.  The 
agreements among P&C, the Florida Department and other interested parties 
including Humana may be modified before or after the Effective Time (subject 
to required consent of the affected parties).

     The Florida Department required that, upon entering into the Agreement, 
Humana make an escrow deposit of $15 million (the "Escrow Deposit") in an 
account held by the Florida Department for the benefit of P&C pursuant to the 
terms of the Escrow Agreement, dated June 2, 1997, among the Florida 
Department, Humana and the Company (the "Escrow Agreement").  See "--The 
Humana Option".

THE HUMANA OPTION

     Upon execution of the Agreement, Humana effected the Escrow Deposit.  
See "--P&C Arrangement".  In consideration for the Escrow Deposit, the 
Company granted Humana an option (the "Humana Option") to purchase for $0.01 
per share a number of shares equal to $15 million divided by 70% of the 
average closing prices of the Common Stock for the five days immediately 
prior to the exercise of the Option.  The Humana Option may be exercised only 
if (i) the Agreement is terminated, (ii) the Escrow Deposit has not been 
returned to Humana and (iii) Humana has obtained all required governmental 
and regulatory approvals required for such a purchase of Common Stock.  The 
Humana Option will expire upon the later of (a) six months following 
termination of the Agreement or (b) 30 days after receipt of such required 
governmental approvals.  The Company has the right to cancel the Humana 
Option at any time by paying Humana $15 million plus interest at 10% per 
annum from the date of the Agreement.

     Under the terms of the Escrow Agreement, the Escrow Deposit is required 
to be returned to Humana if: (i) the Merger is consummated; (ii) the 
Agreement is terminated by (w) either the Company or Humana by reason of the 
stockholders of the Company not adopting the Agreement and approving the 
Merger at the Special Meeting, (x) either the Company or Humana by reason of 
a United States federal or state governmental, regulatory or administrative 
agency or commission having issued an order, decree or ruling or taken any 
other action permanently restraining, enjoining or otherwise prohibiting the 
transactions contemplated by the Agreement that shall have become final and 
non-appealable (provided that the terminating party used best efforts to 
remove such injunction, order or decree), (y) the Company by reason of a 
third party making a Superior Proposal after the Board determines in good 
faith after consultation with its outside counsel that the failure to approve 
such offer would not be consistent with the Board's fiduciary duties to the 
stockholders (provided Humana is given five business days to modify the 
Agreement so that the other proposal would no longer constitute a Superior 
Proposal) or (z) Humana by reason of the Board having withdrawn or modified 
in a manner adverse to Humana its approval or recommendation of the Agreement 
or the Merger or recommending an Alternative Proposal to the stockholders; 
(iii) the Merger is not consummated because (w) the stockholders do not adopt 
the Agreement and approve the Merger, (x) the waiting periods under the 
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR 
Act"), shall not have expired or been terminated, (y) a preliminary or 
permanent injunction or other order by any federal or state court in the 
United States of competent jurisdiction that prevents the consummation of the 
Merger shall have been issued and remains in effect or (z) certain 
governmental notices and reports have not been made or consents or approvals 
obtained; or (iv) the Agreement is terminated as a result of, among other 
things, a change in the Company's financial condition or businesses, assets 
or liabilities other than changes that have not had, individually or in the 
aggregate, a material adverse effect on the Company and its subsidiaries 
taken as a whole (excluding any change or effect relating to P&C, PCA 
Solutions and certain risk contracts between the Company and P&C) and any 
Medicaid contract in Florida, Puerto Rico, one or more Medicaid contracts in 
Texas covering in excess of 25,000 members in the aggregate, any HFCA 
contract in Florida or Texas or any accreditation by the National Committee 
for Quality Assurance held by the Company or any of its 

                                      -27-
<PAGE>

HMO subsidiaries is terminated. The Escrow Deposit is required to be paid to 
P&C if the Agreement is terminated and none of the circumstances set forth in 
the previous sentence occur.

     Upon the issuance of any shares of Common Stock pursuant to the Humana 
Option, the Company is obligated to file a registration statement with the 
Securities and Exchange Commission (the "Commission") covering such shares of 
Common Stock and any other shares of Common Stock to be issued thereafter 
pursuant to the Humana Option.

AMENDMENT OF RIGHTS AGREEMENT

     Before the Effective Time, the Company will amend the Rights Agreement, 
dated as of January 13, 1995, as amended by Amendment No. 1 to Rights 
Agreement, dated November 11, 1996 (the "Rights Agreement"), between the 
Company and Boatmen's Trust Company, as Rights Agent, to provide that the 
Merger shall not trigger any rights to acquire stock of the Company under the 
Rights Agreement.

CONDITIONS TO THE MERGER

     The respective obligations of the Company, Humana and Humana Sub to 
consummate the Merger are subject to the satisfaction of a number of 
conditions, including:

     (a)  The adoption of the Agreement and approval of the Merger by the 
stockholders of the Company;

     (b)  The waiting period pursuant to the provisions of the HSR Act shall 
have expired or been terminated;

     (d)  All consents, authorizations, orders and approvals of (or filings 
or registrations with) any governmental commission, board or other regulatory

subsidiaries (including the Company) following the Effective Time;

     (e)  All consents, authorizations, orders and approvals required under 
federal or state statutes regulating managed care, health maintenance 
organizations required in connection with the execution, delivery or

ability of the Company and its subsidiaries to continue to conduct their 
respective businesses;

     (f)  With respect to each party, the accuracy of representations and 
warranties of the other party (except where an inaccuracy would not have a

in the aggregate, that is or may be materially adverse to the business, 
assets, liabilities, properties, condition (financial or otherwise) or 
results of operations of all or any part of the respective party; PROVIDED, 
HOWEVER, that in respect of the Company any such change or effect relating to 
(i) P&C, (ii) PCA Solutions or (iii) risk contracts between P&C or any of its 
subsidiaries and the Company's Florida HMOs regarding provision of health

covenants and conditions of the other party contained in the Agreement; and

     (g)  With respect to Humana, the Florida Department shall have issued a

     Any conditions described above may be waived by the party or parties 
entitled to the benefit thereof, to the extent permitted by applicable law. 
The Company has no present plans or intentions, and has been advised by 
Humana that it has no present plans or intentions, to waive any of the 
conditions to the Merger.

DISSENTERS' RIGHTS 

     Record holders of Common Stock are entitled to appraisal rights under 
Section 262 of the DGCL in connection with the Merger.  The following 
discussion is an accurate summary of certain provisions of Section 262 and as 
such is not a complete statement of the law pertaining to appraisal rights 
under the DGCL and is qualified in its entirety by the full text of Section 
262, which is reprinted in its entirety as ANNEX D to this Proxy Statement.  
Any such stockholder who wishes to exercise appraisal rights should review 
the following discussion and ANNEX D carefully because failure to timely and 
properly comply with the procedures specified in Section 262 will result in 
the loss of appraisal rights under the DGCL.  Except as set forth herein, 
stockholders of the Company will not be entitled to appraisal rights in 
connection with the Merger.

     Under the DGCL, record holders of shares of Common Stock who follow the 
procedures set forth in Section 262 and have not voted in favor of the 
adoption of the Agreement and the approval of the Merger will be entitled to 
have their shares of Common Stock appraised by the Delaware Court of Chancery 
(the "Court") and to receive payment of the "fair value" of such shares, 
EXCLUSIVE OF ANY ELEMENT OF VALUE ARISING FROM THE ACCOMPLISHMENT OR 
EXPECTATION OF THE MERGER, together with a fair rate of interest, as 
determined by the Court.

     Under Section 262, where a merger agreement is to be submitted for 
approval and adoption at a meeting of stockholders, as is the case of the 
Special Meeting, not less than 20 days prior to the meeting, the Company must 
notify each of the holders of Common Stock at the close of business on the 
Record Date that such appraisal rights are available and include in each such 
notice a copy of Section 262.  This Proxy Statement constitutes such notice.  

     A stockholder wishing to exercise appraisal rights must deliver to the 
Company, before the vote on the adoption of the Agreement and approval of the 
Merger at the Special Meeting, a written demand for appraisal of such 
stockholder's shares of Common Stock.   This written demand for appraisal 
must be in addition to and separate from any proxy vote abstaining from or 
voting against the adoption of the Agreement and the approval of the Merger.  
Voting against, abstaining from voting or failing to vote on the adoption of 
the Agreement and the approval of the Merger will not constitute a demand for 
appraisal within the meaning of Section 262.  In addition, a holder of shares 
of Common Stock wishing to exercise appraisal rights must hold of record such 
shares on the date the written demand for appraisal is made and must continue 
to hold such shares through the Effective Time.

     Any stockholder electing to exercise their appraisal rights under 
Section 262 will not be granted appraisal rights under the DGCL if such 
stockholder has either voted in favor of the adoption of the Agreement or the 
approval of the Merger or consented thereto in writing (including by granting 
the proxy solicited by this Proxy Statement or by returning a signed proxy 
without specifying a vote against the Agreement and the Merger or a direction 
to abstain from such vote).

     Only a holder of record of shares of Common Stock is entitled to assert 
appraisal rights for the shares of Common Stock registered in that holder's 
name.  A demand for appraisal should be executed by or on behalf of the 
holder of record fully and correctly, as the holder's name appears on the 
stock certificates.

     If the shares of Common Stock are owned of record in a fiduciary 
capacity, such as by a trustee, guardian or custodian, execution of the 
demand should be made in that capacity, and if the shares of Common Stock are 
owned of record by more than one person, as in a joint tenancy or tenancy in 
common, the demand should be executed by or on behalf of all joint owners.  
An authorized agent, including one or more joint owners, may execute a demand 
for appraisal on behalf of a holder of record; however, the agent must 
identify the record owner or owners and expressly 

                                      -29-
<PAGE>

disclose the fact that, in executing the demand, the agent is agent for such 
owner or owners.  A record holder such as a broker who holds Common Stock as 
nominee for several beneficial owners may exercise appraisal rights with 
respect to the Common Stock held for one or more beneficial owners while not 
exercising such rights with respect to the Common Stock held for other 
beneficial owners; in such case, the written demand should set forth the 
number of shares as to which appraisal is sought and where no number of 
shares is expressly mentioned the demand will be presumed to cover all Common 
Stock held in the name of the record owner.  Holders of Common Stock who hold 
their shares in brokerage accounts or other nominee forms and who wish to 
exercise appraisal rights are urged to consult with their brokers to 
determine the appropriate procedures for the making of a demand for appraisal 
by such nominee.  All written demands for appraisal of Common Stock should be 
mailed or delivered to Jose M. Menendez, Corporate Secretary, Physician 
Corporation of America, 6101 Blue Lagoon Drive, Miami, Florida 33126, 
separate from any proxy or vote against the adoption of the Agreement and the 
approval of the Merger, so as to be received before the vote on the adoption 
of the Agreement and approval of the Merger at the Special Meeting.  

     Within 10 days after the Effective Time, the Company, as the surviving 
corporation in the Merger, must send a notice as to the effectiveness of the 
Merger to each person who has satisfied the appropriate provisions of Section 
262.  Within 120 days after the Effective Time, but not thereafter, the 
Company, or any holder of shares of Common Stock entitled to appraisal rights 
under Section 262 and who has complied with the foregoing procedures, may 
file a petition in the Court demanding a determination of the fair value of 
such shares.  The Company is not under any obligation, and has no present 
intention, to file a petition with respect to the appraisal of the fair value 
of the shares of Common Stock.  Accordingly, it is the obligation of the 
stockholders to initiate all necessary action to perfect their appraisal 
rights within the time prescribed in Section 262.

     Within 120 days after the Effective Time, any record holder of shares of 
Common Stock who has complied with the requirements for exercise of appraisal 
rights will be entitled, upon written request, to receive from the Company a 
statement setting forth the aggregate number of shares of the Common Stock 
with respect to which demands for appraisal have been received and the 
aggregate number of holders of such shares.  Such statements must be mailed 
within 10 days after a written request therefor has been received by the 
Company or within 10 days after expiration of the period for delivery of 
demands for appraisal, whichever is later.

     If a petition for an appraisal is timely filed, after a hearing of such 
petition, the Court will determine the holders of shares of Common Stock 
entitled to appraisal rights and will appraise the "fair value" of the shares 
of Common Stock, EXCLUSIVE OF ANY ELEMENT OF VALUE ARISING FROM THE 
ACCOMPLISHMENT OR EXPECTATION OF THE MERGER, together with a fair rate of 
interest, if any, to be paid upon the amount determined to be the fair value. 
Holders considering seeking appraisal should be aware that the fair value of 
their shares of Common Stock as determined under Section 262 could be more 
than, the same as or less than the $7.00 in cash per share that they would 
otherwise receive if they did not seek appraisal of their shares of Common 
Stock.  The Delaware Supreme Court has stated that "proof of value by any 
techniques or methods which are generally considered acceptable in the 
financial community and otherwise admissible in court" should be considered 
in the appraisal proceedings.  More specifically, the Delaware Supreme Court 
has stated that:  "Fair value, in an appraisal context, measures `that which 
has been taken from [the shareholder], VIZ., his proportionate interest in a 
going concern.'  In the appraisal process the corporation is valued `as an 
entity,' not merely as a collection of assets or by the sum of the market 
price of each share of its stock.  Moreover, the corporation must be viewed 
as an on-going enterprise, occupying a particular market position in the 
light of future prospects."  In addition, Delaware courts have decided that 
the statutory appraisal remedy, depending on factual circumstances, may or 
may not be a dissenter's exclusive remedy.  The Court will also determine the 
amount of interest, if any, to be paid upon the amounts to be received by 
persons whose shares of Common Stock have been appraised.  The costs of the 
action may be determined by the Court and taxed upon the parties as the Court 
deems equitable.  The Court may also order that all or a portion of the 
expenses incurred by any holder of the shares of Common Stock in connection 
with an appraisal, including, without limitation, reasonable attorneys' fees 
and the fees and expenses of experts utilized in the appraisal proceeding, be 
charged pro rata against the value of all of the shares of Common Stock 
entitled to appraisal.

                                      -30-
<PAGE>

     Any holder of shares of Common Stock who has duly demanded an appraisal 
in compliance with Section 262 will not, after the Effective Time, be 
entitled to vote the shares of Common Stock subject to such demand for any 
purpose or be entitled to the payment of dividends or other distributions on 
those shares (except dividends or other distributions payable to the holders 
of record of shares of Common Stock as of a date prior to the Effective Time).

     If any holder of shares of Common Stock who demands appraisal of shares 
under Section 262 fails to perfect, or effectively withdraws or loses, the 
right to appraisal, as provided in the DGCL, the shares of Common Stock of 
such holder will be converted into the right to receive $7.00 in cash per 
share of Common Stock in accordance with the Agreement.  A holder of shares 
of Common Stock will fail to perfect, or effectively lose, the right to 
appraisal if no petition for appraisal is filed within 120 days after the 
Effective Time.  A holder may withdraw a demand for appraisal by delivering 
to the Company a written withdrawal of the demand for appraisal and 
acceptance of the Merger, except that (i) any such attempt to withdraw made 
more than 60 days after the Effective Time will require the written approval 
of the Company, as the surviving corporation in the Merger, and (ii) no 
appraisal proceeding in the Court may be dismissed as to any stockholder 
without the approval of the Court (such approval may be conditioned upon such 
terms as the Court deems just).
                                       
     FAILURE TO FOLLOW THE STEPS REQUIRED BY SECTION 262 OF THE DGCL FOR
      PERFECTING APPRAISAL RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS.

     The foregoing is an accurate summary of certain of the provisions of 
Section 262 of the DGCL and is qualified in its entirety by reference to the 
full text of such section, a copy of which is attached hereto as ANNEX D.

EXPENSES OF THE MERGER

     The Agreement provides that the Company, Humana and Humana Sub shall 
each pay their own costs and expenses in connection with the Merger.  In the 
event the Merger is consummated, it is anticipated that the Company's 
expenses will be approximately $12 million, including consulting/noncompete 
payments to executive officers.  In the event the Merger is not consummated, 
it is anticipated that the Company's expenses will be approximately $2 
million.  In addition, in the event the Merger is not consummated due to the 
circumstances specified in "--Breakup Fee" below, the Company will be 
obligated to pay Humana a breakup fee in the amount of up to $17 million, 
plus documented expenses not to exceed $1.5 million.

AMENDMENT

     The Agreement provides that the parties thereto may make any amendment 
or modification to the Agreement only by an instrument in writing executed by 
Humana, Humana Sub and the Company.  However, after the Agreement is adopted 
and the Merger is approved by the stockholders of the Company, no amendment 
to the Agreement that by law would require the approval of the stockholders 
of the Company may be made without such further approval.

NO SOLICITATION

     Prior to the Effective Time, the Company has agreed in the Agreement: 
(a) that neither it nor any of its subsidiaries shall, and it shall direct 
and use its best efforts to cause its officer, directors, employees, agents 
and representatives (including, without limitation, any investment banker, 
attorney or accountant retained by it or any of its subsidiaries) not to, 
initiate, solicit or encourage, directly or indirectly, any inquiries or the 
making or implementation of any Alternative Proposal or engage in any 
negotiations concerning, or provide any confidential information or data to, 
or have any discussions with, any person relating to an Alternative Proposal, 
or release any third party from any obligations under any existing standstill 
agreement or arrangement relating to any Alternative Proposal, or otherwise 
facilitate any effort or attempt to make or implement an Alternative 
Proposal; (b) that it will immediately cease and cause to be terminated any 
existing activities, discussions or negotiations with any parties conducted 
heretofore with respect to any of the foregoing, and it will take the 
necessary steps to inform the individuals or entities 

                                      -31-
<PAGE>

referred to above of these obligations; and (c) that it will notify Humana 
immediately if any such inquiries or proposals are received by, any such 
information is requested from, or any such negotiations or discussions are 
sought to be initiated or continued with, it; PROVIDED, HOWEVER, that nothing 
contained in this provision shall prohibit the Board from furnishing 
information to any person or entity that makes an Alternative Proposal, if, 
and only to the extent that, (A) the Board determines in good faith after 
consultation with outside counsel that such action is required for the Board 
to comply with its fiduciary duties to stockholders imposed by law, (B) the 
Alternative Proposal is a Superior Proposal, (C) the Company provides Humana 
with a true and complete copy of such proposal as soon as practicable after 
the receipt thereof, and (D) such action is required to comply with Rule 
14e-2 promulgated under the Securities and Exchange Act of 1934, as amended, 
with regard to an Alternative Proposal.  This provision does not (x) permit 
with the Company to terminate the Agreement (except as specifically 
provided), (y) permit the Company to have discussions, negotiations or to 
enter into any agreement with respect to an Alternative Proposal during the 
term of the Agreement (it being agreed that during the term of the Agreement, 
the Company shall not enter into any discussion, negotiation or agreement 
with any person that provides for, or in any way facilitates, an Alternative 
Proposal (other than a confidentiality agreement in customary form)), or (z) 
affect any other obligation of the Company under the Agreement.

BREAKUP FEE

     Pursuant to the Agreement, the Company has agreed to pay Humana $17 
million in cash, plus documented expenses not to exceed $1.5 million, if (x) 
a person makes an Alternative Proposal for the Company and thereafter either 
(i) the Company terminates the Agreement in accordance with its terms by 
reason of such Alternative Proposal or (ii) Humana or the Company terminates 
the Agreement by reason of the stockholders of the Company not adopting the 
Agreement and approving the Merger at the Special Meeting or (y) Humana 
terminates the Agreement by reason of the Board having withdrawn or modified 
in a manner adverse to Humana its approval or recommendation of the Agreement 
or the Merger or recommending an Alternative Proposal to the Company 
stockholders. In addition, if the Agreement is terminated for any other 
reason (other than by reason of a breach of the representations and 
warranties of Humana or Humana Sub or the failure of Humana or Humana Sub to 
comply with their obligations under the Agreement) and within 12 months 
thereafter any Alternative Proposal is consummated, the Company has agreed to 
pay Humana the lesser of (i) $17 million or (ii) 3.5% of the aggregate value 
of the other business combination, plus documented out-of-pocket expenses 
incurred by Humana in connection with the Agreement not to exceed $1.5 
million.

TERMINATION

     The Agreement may be terminated at any time prior to the closing of the 
transactions contemplated by the Agreement by (i) mutual written consent of 
the Company and Humana, or (ii) either the Company or Humana if (w) the 
Merger is not consummated by October 31, 1997, (x) the stockholders of the 
Company do not approve the Merger at the Special Meeting, (y) a United States 
federal or state governmental, regulatory or administrative agency or 
commission shall have issued an order, decree or ruling or taken any other 
action permanently restraining, enjoining or otherwise prohibiting the 
transactions contemplated by the Agreement which shall have become final and 
non-appealable (provided that the terminating party used best efforts to 
remove such injunction, order or decree) or (z) the other party to the 
Agreement has materially breached a representation, warranty or covenant in 
the Agreement and such breach is not cured after a specified notice period.  
In addition, the Company may terminate the Agreement if (i) the Board 
receives a Superior Proposal, (ii) five business days shall have elapsed 
after delivery to Humana of written notice by the Company informing Humana 
that the Board has determined that a Superior Proposal has been made and 
during such five business day period the Company shall have fully cooperated 
with Humana in good faith with the intent of enabling Humana to agree to a 
modification of the terms and conditions of the Agreement (including the 
merger consideration) so that the Alternative Proposal would not constitute a 
Superior Proposal as compared to the terms and conditions of the Agreement as 
proposed to be modified by Humana (the "Modified Agreement") and (iii) at the 
end of such five business day period, the Board shall continue to determine 
in good faith (after consultation with a nationally recognized investment 
banking firm which provided a written opinion to such effect) that such 
Alternative Proposal continues to constitute a Superior Proposal as compared 
to the Modified Agreement (provided, however, that the Company's right to 
terminate the Agreement pursuant to this provision shall not be available (A) 
if the Company 

                                      -32-
<PAGE>

has breached in any material respect its obligations under "--No 
Solicitation" or (B) if, prior to or concurrently with any purported 
termination of the Agreement pursuant to this provision, the Company shall 
not have paid the fee contemplated under "--Breakup Fee").  Humana may also 
terminate the Agreement if the Board shall have withdrawn or modified in a 
manner adverse to Humana its approval or recommendation of the Agreement or 
the Merger or shall have recommended an Alternative Proposal to the 
stockholders.

     As used in the Agreement, a "Superior Proposal" means a bona fide 
written offer to acquire the Company pursuant to a merger, consolidation, 
share exchange, purchase of a substantial portion of assets, business 
combinations or other similar transaction (which offer shall not be subject 
to any conditions that are more onerous to the Company than the conditions to 
Humana and Humana Sub's obligations to consummate the Merger; PROVIDED, 
HOWEVER, that such offer may be subject to confirmatory due diligence to be 
effected within a five business day period): (i) that the Board determines, 
in good faith after consultation with a nationally recognized investment 
banking firm which provided a written opinion to such effect, provides a 
higher value per share to the stockholders than the $7.00 in cash after 
taking into account, among other things, the reasonable likelihood the 
Effective Time will occur as compared to when the closing of such Alternative 
Proposal will occur; (ii) that is not subject to any financing condition (and 
the offeror has on hand funds available or committed financing to consummate 
the offer and the transactions contemplated thereby); (iii) does not have any 
condition to closing or rights to terminate more onerous to the Company than 
the provisions set forth in the Agreement and (iv) does not involve any 
substantive legal impediments that are reasonably likely to prevent such 
Alternative Proposal from closing.

CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

     The following is a summary of the principal federal income tax 
consequences of the Merger to holders whose shares of Common Stock are 
converted to cash in the Merger (including pursuant to the exercise of 
dissenters' rights).  The discussion applies only to holders of shares of 
Common Stock in whose hands shares of Common Stock are capital assets, and 
may not apply to shares of Common Stock received pursuant to the exercise of 
employee stock options or otherwise as compensation, or to holders of shares 
of Common Stock who are in special tax situations (such as insurance 
companies, tax-exempt organizations, non-U.S. persons or persons who have 
engaged in "straddles" or other hedging transactions with respect to their 
shares of Common Stock).

     THE FEDERAL INCOME TAX CONSEQUENCES SET FORTH BELOW ARE INCLUDED FOR 
GENERAL INFORMATIONAL PURPOSES ONLY AND ARE BASED UPON CURRENT LAW.  BECAUSE 
INDIVIDUAL CIRCUMSTANCES MAY DIFFER, EACH HOLDER OF SHARES OF COMMON STOCK 
SHOULD CONSULT SUCH HOLDER'S OWN TAX ADVISOR TO DETERMINE THE APPLICABILITY 
OF THE RULES DISCUSSED BELOW TO SUCH HOLDER AND THE PARTICULAR TAX EFFECTS OF 
THE MERGER, INCLUDING THE APPLICATION AND EFFECT OF FOREIGN, STATE, LOCAL AND 
OTHER INCOME TAX LAWS.

     GENERAL.  The receipt of cash for shares of Common Stock pursuant to the 
Merger (including pursuant to the exercise of dissenters' rights) will be a 
taxable transaction for federal income tax purposes and also may be a taxable 
transaction under foreign, state, local and other income tax laws.  In 
general, for federal income tax purposes, a holder of shares of Common Stock 
will recognize gain or loss equal to the difference between his or her 
adjusted tax basis in the shares of Common Stock converted to cash in the 
Merger and the amount of cash received therefor.  Gain or loss must be 
determined separately for each block of shares of Common Stock (i.e., shares 
of Common Stock acquired at the same cost in a single transaction) converted 
to cash in the Merger. Such gain or loss generally will be capital gain or 
loss and will be long-term capital gain or loss if, on the date of the 
Merger, the shares of Common Stock were held for more than one year.  If a 
holder exercises his dissenters' rights and receives an amount treated as 
interest for federal income tax purposes, such amount will be taxed as 
ordinary income.

     BACKUP WITHHOLDING.  Payments in connection with the Merger may be 
subject to "backup withholding" at a rate of 31%.  Backup withholding 
generally applies if the holder (i) fails to furnish such holder's social 
security number or taxpayer identification number ("TIN"), (ii) furnishes an 
incorrect TIN, (iii) is subject to backup withholding due 

                                      -33-
<PAGE>

to previous failures to include reportable interest or dividend payments on 
such holder's federal income tax return or (iv) under certain circumstances, 
fails to provide a certified statement, signed under penalties of perjury, 
that the TIN provided is such holder's correct number and that such holder is 
not subject to backup withholding.  Backup withholding is not an additional 
tax, but rather it is an advance tax payment that is subject to refund if and 
to the extent that it results in an overpayment of tax.  Certain taxpayers 
are generally exempt from backup withholding, including corporations and 
financial institutions.  Certain penalties apply for failure to furnish 
correct information and for failure to include reportable payments in income.

REGULATORY APPROVALS

     INSURANCE REGULATORY AND SIMILAR APPROVALS

     The governmental and regulatory filings and approvals identified below 
must be made and obtained before the Merger may be consummated without any 
conditions imposed by governmental authorities (other than any conditions 
that are ministerial in nature or are customary for transactions of a similar 
nature).

     The Merger and related transactions are subject to prior written 
approval by the Florida Department, the Texas Department of Insurance and the 
Office of the Commissioner of Insurance of Puerto Rico.  Filings have been 
made with each of these entities and additional requests for documents have 
been made by the Florida Department and the Texas Department of Insurance, 
which have been responded to.  Under the insurance laws of these 
jurisdictions, a detailed statement containing information describing the 
proposed transactions and the business operations, management, financial 
condition and resources, and business plans of Humana, the entity acquiring 
ultimate control of the Company's subsidiary health maintenance organizations 
and insurance companies, must be filed with each such jurisdiction's 
insurance commissioner.  In some or all such jurisdictions a public hearing 
may be held at the initiative of the regulatory agency.  The agencies' review 
of the filed statements and other information collected or requested by the 
agencies generally requires from 30 to 90 days, although a shorter or longer 
period may suffice or be required. The insurance commissioner may ultimately 
approve or disapprove the application.  Approvals are often given in formal 
orders that may impose terms and conditions stipulated by the agencies.  See 
"--P&C Arrangement" for a summary of additional procedures and conditions 
affecting the acquisition of P&C both before and after the Effective Time.

     Filings with and approvals or consents of other governmental regulatory 
authorities will also be required in connection with the Merger.  These 
authorities include: (a) the Florida Agency for Health Care Administration, 
which has jurisdiction over Medicaid prepaid health plans in Florida, (b) the 
Texas Department of Health, which has a comparable role in that state, (c) 
the Health Care Financing Administration, a federal agency that administers 
Medicaid and Medicare contracts and (d) the Bermuda Monetary Authority, which 
regulates a reinsurance subsidiary of the Company in that jurisdiction.  
These authorities may also impose conditions on their approval of or consent 
to the Merger and related transactions.

     ANTITRUST REVIEW AND CONSIDERATIONS

     The HSR Act and rules and regulations thereunder provide that certain 
transactions such as the Merger may not be consummated until all required 
information and documents have been submitted to the Antitrust Division of 
the U.S. Department of Justice ("DOJ") and Federal Trade Commission ("FTC") 
and applicable waiting periods have expired or been terminated.  Humana and 
the Company made HSR filings with the DOJ and FTC on July 2, 1997, thus 
commencing the 30 day waiting period.  The waiting period has expired without 
any requests from either the DOJ or the FTC for additional information or 
material from Humana or the Company.

     The DOJ and FTC frequently scrutinize the effect and legality under 
federal antitrust laws of transactions such as the Merger.  Notwithstanding 
expiration of the HSR waiting period, at any time before or after the 
Effective Time, the FTC, the DOJ, any state or others may bring actions under 
federal or state antitrust and competition laws, seeking to enjoin 
consummation of the Merger or seeking divestiture by Humana of some or all of 
the stock, operations, or 

                                      -34-
<PAGE>

subsidiaries of the Company.  Private parties may also seek to take legal 
action under the antitrust laws under certain circumstances.  There is at 
present no assurance that the Merger will not be challenged on antitrust 
grounds or that such a challenge, if made, would be unsuccessful or would not 
require the parties to accept unexpected or adverse conditions to consummate 
the Merger.

STATE ANTITAKEOVER STATUTES

     A number of states have adopted laws and regulations applicable to 
attempts to acquire securities of corporations that are incorporated, or have 
substantial assets, stockholders, principal executive offices or principal 
places of business, or whose business operations otherwise have substantial 
effects in such states.

     The Company conducts business, and the Company's stockholders are 
resident, in a number of states throughout the United States, some of which 
have enacted antitakeover statutes.  The Company does not know to what extent 
each of these statutes may apply to the Merger.  Should any person seek to 
apply any state antitakeover statute to the Merger, the Company will take 
such action as then appears desirable, which may include challenging the 
validity or applicability of any such statute in appropriate court 
proceedings.  In the event that it is asserted that one or more antitakeover 
statutes is applicable to the Merger, the Company, Humana or Humana Sub may 
be required to file certain information with, or receive approvals from, the 
relevant governmental authorities.

ACCOUNTING TREATMENT

     The Merger will be treated as a purchase transaction for accounting 
purposes.

                                SOURCE OF FUNDS

     The aggregate amount of cash required to consummate the Merger and pay 
related fees and expenses, including payment of Options and employee 
severance costs, is approximately $298 million.  The amount of funds required 
to consummate the Merger will be provided by Humana or Humana Sub.  In 
addition, Humana expects to repay all of the Company's existing indebtedness 
for borrowed money (which had a principal amount of approximately $123 
million as of June 30, 1997).  Humana expects to obtain the requisite funds 
to consummate the Merger through a combination of cash and cash equivalents 
on hand and borrowings under a $1.5 billion five year revolving credit 
facility (the "Credit Facility") for which Humana has received a commitment 
letter from the Chase Manhattan Bank ("Chase"), which will act as the sole 
administrative agent for the Credit Facility.  The Credit Facility will 
contain customary conditions to borrowing, representations and warranties, 
covenants and events of default. Amounts under the Credit Facility will 
generally be able to be borrowed, repaid and reborrowed from time to time.  
The Credit Facility will replace an existing $600 million credit facility 
(the "Existing Facility") that Humana currently has with a syndicate of 
lenders, including Chase as the sole administrative agent, which would have 
expired in September 2000.  As of June 20, 1997, Humana had the entire $600 
million of credit available under the Existing Facility. It is anticipated 
that the terms of the Credit Facility will be substantially similar to the 
Existing Facility.  

     Until such funds are needed for the conversion of shares of Common Stock 
into the right to receive $7.00 in cash and payment for Options, the cash in 
the Payment Fund may temporarily be invested, as directed by Humana, in 
obligations of or guaranteed by the United States of America, with remaining 
maturities not exceeding 180 days, in commercial paper obligations receiving 
the highest rating from either Moody's Investors Service, Inc. or Standard & 
Poor's Corporation or in certificates of deposit, or bankers' acceptances of 
commercial banks with capital exceeding $100 million, with the net profits or 
interest earned paid to Humana.

                   INTERESTS OF CERTAIN PERSONS IN THE MERGER

     The Agreement provides that Humana will indemnify the officers, 
directors and employees of the Company and its subsidiaries from all 
liabilities arising out of the transactions contemplated by the Agreement to 
the fullest extent permitted by law.  The Agreement also provides that all 
rights to indemnification existing in favor of those persons provided for in 
the Company's Certificate of Incorporation or By-Laws with respect to matters 
occurring through the Effective Time shall survive the Merger and continue in 
full force for a period of not less than six years from the Effective Time. 
Humana has agreed to cause the Surviving Corporation to maintain in effect 
for not less than six years after the Effective Time the current policies of 
directors' and officers' liability insurance maintained by the Company with 
respect to matters occurring on or prior to the Effective Time; PROVIDED, 
HOWEVER, that the Surviving Corporation may substitute therefor policies of 
at least the same coverage (with carriers comparable to the Company's 
existing carriers) containing terms and conditions which are no less 
advantageous to the indemnified parties; PROVIDED, FURTHER, that Humana shall 
not be required in order to maintain or procure such coverage to pay an 
annual premium in excess of 150% of the current annual premium paid by the 
Company for its existing coverage (the "Cap"); and PROVIDED, FURTHER, that if 
equivalent coverage cannot be obtained, or can be obtained only by paying an 
annual premium in excess of the Cap, Humana shall only be required to obtain 
as much coverage as can be obtained by paying an annual premium equal to the 
Cap.

     Each of the executive officers of the Company are parties to existing 
salary continuation agreements with the Company that provide for aggregate 
total payments of up to 18 months salary and a payment for the cash value of 
their Options, as defined in the agreements, which the Company estimates 
together will approximate $3 million.  In addition, pursuant to consulting 
agreements entered into by and between the Company and Dr. Kardatzke and 
Messrs. Kilissanly and Donnelly on June 2, 1997, in the event that the Merger 
is effected and to the extent that such officers of the Company are employed 
by the Company on the Effective Time, they will be entitled to receive 
payments aggregating $682,228, $652,117 and $415,655 respectively, in 
consideration for consulting services to be rendered to the Company during 
the year following the Effective Time.  The consulting agreements also 
provide that Dr. Kardatzke and Messrs. Kilissanly and Donnelly will not 
solicit employees from the Company or compete with the Company in Puerto 
Rico.  In addition, the Board approved payment of a success fee of $250,000 
to be paid upon consummation of the Merger to Mr. Clark Mandigo, a 
non-employee director of the Company, in connection with his negotiation of 
the Agreement on behalf of the Company.

parties hereto hereby agree as follows:
 
                                   ARTICLE I
                                  THE MERGER.

<PAGE>
                                  ARTICLE III
                              CONVERSION OF SHARES
 
    Section 3.1.  MERGER CONSIDERATION.  On the Effective Date, by virtue of the
Merger and without any action on the part of any holder of any Common Stock, par
value $.01 per share, of the Company ("Company Common Stock"):
 
    (a) All shares of Company Common Stock which are held by the Company or any
Subsidiary of the Company, and any shares of Company Common Stock owned by
Parent, Sub or any other subsidiary of Parent, shall be canceled. As used in
this Agreement, "Subsidiary" means any significant corporation, partnership,
joint venture or other legal entity of which Parent or the Company, as the case
may be (either alone or through or together with any other Subsidiary), owns
directly or indirectly, 50% or more of the stock or other equity interests the
holders of which are generally entitled to vote for the election of the board of
directors or other governing body of such corporation or other legal entity.
 
    (b) Subject to Section 3.3, each remaining outstanding share of Company
Common Stock shall be converted into and represent the right to receive $7.00
(the "Merger Consideration") in accordance with Section 3.2.
 
    (c) In the event of any stock dividend, stock split, reclassification,
recapitalization, combination or exchange of shares with respect to, or rights
issued in respect of, Company Common Stock after the date hereof, the Merger
Consideration shall be adjusted accordingly.
 
    (d) Each issued and outstanding share of capital stock of Sub shall be
converted into and become one fully paid and nonassessable share of common stock
of the Surviving Corporation.
 
    Section 3.2.  PAYMENT PROCEDURES.  (a) Prior to the Effective Date, Parent
shall select a Payment Agent, which shall be Parent's Transfer Agent or such
other person or persons reasonably satisfactory to the Company, to act as
Payment Agent for the Merger (the "Payment Agent").
 
    (b) As soon as practicable after the Effective Date (but in no event more
than five days thereafter), Parent shall instruct the Payment Agent to mail to
each holder of a certificate or certificates evidencing shares of Company Common
Stock (other than Dissenting Shares, as defined in Section 3.3) ("Certificates")
(i) a letter of transmittal (which shall include a Substitute Form W-9 and shall
specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon proper delivery of such Certificates to the
Payment Agent) and (ii) instructions to effect the surrender of the Certificates
in exchange for the Merger Consideration. Each holder of Company Common Stock,
upon surrender to the Payment Agent of such holder's Certificates with the
letter of transmittal, duly executed, and such other customary documents as may
be required pursuant to such instructions, shall be paid the amount to which
such holder is entitled, pursuant to this Agreement, of cash as payment of the
Merger Consideration (without any interest accrued thereon). Until so
surrendered, each Certificate shall after the Effective Date represent for all
purposes only the right to receive the Merger Consideration. In the event any
Certificate shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the person claiming such Certificate to be lost,
stolen or destroyed and, if required by the Surviving Corporation, the posting
by such person of a bond in such reasonable amount as the Surviving Corporation
may direct as indemnity against any claim that may be made against it with
respect to such Certificate, the Paying Agent will deliver in exchange for such
lost, stolen or destroyed Certificate the Merger Consideration payable in
respect thereof pursuant to this Agreement.
 
    (c) At the closing of the transactions contemplated by this Agreement (the
"Closing"), Parent shall deposit in trust with the Payment Agent, for the
ratable benefit of the holders of Company Common Stock, the appropriate amount
of cash to which such holders are entitled pursuant to this Agreement for
payment of the Merger Consideration (the "Payment Fund"). The Payment Agent
shall, pursuant to irrevocable instructions, make the payments to the holders of
Company Common Stock as set forth in this Agreement.
 
                                      A-2
<PAGE>
    (d) If any delivery of the Merger Consideration is to be made to a person
other than the registered holder of the Certificates surrendered in exchange
therefor, it shall be a condition to such delivery that the Certificate so
surrendered shall be properly endorsed or be otherwise in proper form for
transfer and that the person requesting such delivery shall (i) pay to the
Payment Agent any transfer or other taxes required as a result of delivery to a
person other than the registered holder or (ii) establish to the satisfaction of
the Payment Agent that such tax has been paid or is not payable.
 
    (e) Any portion of the Payment Fund that remains undistributed to the
holders of Company Common Stock as of the first anniversary of the Effective
Date shall be delivered to Parent upon demand, and any holder of Company Common
Stock who has not theretofore complied with the exchange requirements of this
Section shall have no further claim upon the Payment Agent and shall thereafter
look only to Parent for payment of the Merger Consideration.
 
    (f) If a Certificate has not been surrendered prior to the date on which any
receipt of Merger Consideration would otherwise escheat to or become the
property of any governmental agency, such Certificate shall, to the extent
permitted by applicable law, be deemed to be canceled and no money or other
property will be due to the holder thereof.
 
    (g) The Payment Agent may invest cash in the Payment Fund, as directed by
Parent, on a daily basis, provided that all such investments shall be in
obligations of or guaranteed by the United States of America with remaining
maturities not exceeding 180 days, in commercial paper obligations receiving the
highest rating from either Moody's Investors Services, Inc. or Standard & Poor's
Corporation, or in certificates of deposit or banker's acceptances of commercial
banks with capital exceeding $100 million (collectively, "Permitted
Investments"). The maturities of Permitted Investments shall be such as to
permit the Payment Agent to make prompt payment to former stockholders of the
Company entitled thereto as contemplated by this Section. Parent shall promptly
replenish the Payment Fund to the extent of any losses incurred as a result of
Permitted Investments. Any interest and other income resulting from such
investments shall be paid to Parent. If for any reason (including losses) the
Payment Fund is inadequate to pay the amounts to which holders of Company Common
Stock shall be entitled under this Agreement, Parent shall in any event be
liable for payment thereof. The Payment Fund shall not be used for any purpose
not specifically provided for in this Agreement.
 
    Section 3.3.  DISSENTING SHARES.  (a) Notwithstanding any other provision of
this Agreement to the contrary, shares of Company Common Stock that are
outstanding immediately prior to the Effective Date and which are held by
holders who shall have not voted in favor of the Merger or consented thereto in
writing and who shall have demanded properly in writing appraisal for such
shares in accordance with Section 262 of the DGCL and who shall not have
withdrawn such demand or otherwise have forfeited appraisal rights
(collectively, the "Dissenting Shares") shall not be converted into or represent
the right to receive the Merger Consideration. Such holders shall be entitled to
receive payment of the appraised value of such shares, except that all
Dissenting Shares held by holders who shall have failed to perfect or who
effectively shall have withdrawn or lost their rights to appraisal of such
shares under such Section 262 shall thereupon be deemed to have been converted
into and to have become exchangeable, as of the Effective Date, for the right to
receive, without any interest thereon, the Merger Consideration, upon surrender
of the Certificates evidencing such shares.
 
    (b) The Company shall give Parent (i) prompt notice of any demands for
appraisal received by the Company, withdrawals of such demands, and any other
instruments served pursuant to the DGCL and received by the Company and (ii) the
opportunity to participate and direct all negotiations and proceedings with
respect to demands for appraisal under the DGCL. The Company shall not, except
with the prior written consent of Parent, make any payment with respect to any
demands for appraisal, or offer to settle, or settle, any such demands.
 
    Section 3.4.  STOCK OPTIONS.  (a) All options (the "Options") to acquire
shares of Company Common Stock (whether vested or unvested), other than those
set forth in paragraph (d) below, shall be canceled as
 
                                      A-3
<PAGE>
of the Effective Date. In consideration of such cancellation, each holder of
Options shall have only the right to receive from the Company the payments (if
any) as specified below:
 
        (i) Each employee of the Company or any of its Subsidiaries employed as
    of the Effective Date shall be entitled to receive the Cash Value (as such
    term is defined in the form of Salary Continuation Agreement attached to
    SCHEDULE 3.4 (the "Salary Continuation Agreement")) of each such canceled
    Option under either of the following circumstances: (x) the employee is
    employed by Parent or any of its Subsidiaries (including the Company) at the
    end of the Initial Benefit Period specified in the Salary Continuation
    Agreement to which the employee is a party or, if such employee is not a
    party to a Salary Continuation Agreement, six months from the Effective Date
    (such employee's Initial Benefit Period being deemed to be six months for
    purposes of computing the Cash Value) or (y) the employee's employment is
    terminated under circumstances resulting in a Termination Date (as such term
    is defined in the Salary Continuation Agreement). The payment shall be made
    upon the earlier to occur of clauses (x) and (y).
 
        (ii) Each holder of an Option who was not an employee of the Company or
    any of its Subsidiaries as of the Effective Date or was a non-employee
    director of the Company shall have the right to receive a cash payment in
    the amount (if any) equal to the number of shares of Company Common Stock
    subject to each canceled Option multiplied by the difference (if positive)
    between the exercise price per share of Company Common Stock covered by the
    canceled Option and the Merger Consideration.
 
    (b) As a condition to making any payment specified in clause (a) above, each
Option holder shall acknowledge in writing that all Options held by such person
have been canceled in consideration of the right to receive such payment and, in
the case of employees who are parties to the Salary Continuation Agreement, in
full satisfaction of all rights under paragraph 2(b)(iv) of such employee's
Salary Continuation Agreement.
 
    (c) Prior to the Effective Date, the Company shall take such additional
actions as are necessary under applicable law and the applicable agreement and
the Company's option plans to ensure that each Option shall, from and after the
Effective Date, represent only the right to receive the payments specified in
clause (a) above.
 
    (d) The Company shall take all actions necessary to vest all options held by
the University of Miami and The Jackson Memorial Foundation as contemplated by
Section 12.B(i) of the applicable Stock Option Agreement so that from and after
the Effective Date each such option represents the right to receive the Merger
Consideration.
 
    Section 3.5.  STOCKHOLDERS' MEETINGS.  The Company shall take all action
necessary, in accordance with applicable law and its Certificate of
Incorporation and By-laws, to convene a special meeting of the holders of
Company Common Stock (the "Company Meeting") as promptly as practicable for the
purpose of considering and taking action upon this Agreement. Subject to the
exercise of its good faith judgment as to its fiduciary duties to its
stockholders imposed by law, as advised by outside counsel, the Board of
Directors of the Company will recommend that holders of Company Common Stock
vote in favor of and approve the Merger and the adoption of the Agreement at the
Company Meeting. At the Company Meeting, all of the shares of Company Common
Stock then owned by Parent, Sub, or any other subsidiary of Parent, or with
respect to which Parent, Sub, or any other subsidiary of Parent holds the power
to direct the voting, will be voted in favor of approval of the Merger and
adoption of this Agreement.
 
    Section 3.6.  CLOSING OF THE COMPANY'S TRANSFER BOOKS.  At the Effective
Date, the stock transfer books of the Company shall be closed and no transfer of
shares of Company Common Stock shall be made thereafter. In the event that,
after the Effective Date, Certificates are presented to the Surviving
Corporation, they shall be canceled and exchanged for the Merger Consideration
as provided in Sections 3.1(b) and 3.2.
 
                                      A-4
<PAGE>
    Section 3.7.  ASSISTANCE IN CONSUMMATION OF THE MERGER.  Each of Parent, Sub
and the Company shall provide all reasonable assistance to, and shall cooperate
with, each other to bring about the consummation of the Merger as soon as
possible in accordance with the terms and conditions of this Agreement. Parent
shall cause Sub to perform all of its obligations in connection with this
Agreement.
 
    Section 3.8.  CLOSING.  The Closing shall take place (i) at the offices of
Fried, Frank, Harris, Shriver & Jacobson, One New York Plaza, New York, New York
10004, at 9:00 A.M. local time on the day which is at least one business day
after the day on which the last of the conditions set forth in Article VIII
(other than those that can only be fulfilled on the Effective Date) is fulfilled
or waived or (ii) at such other time and place as Parent and the Company shall
agree in writing.
 
    Section 3.9.  TRANSFER TAXES.  Parent and Company shall cooperate in the
preparation, execution and filing of all returns, applications or other
documents regarding any real property transfer, stamp, recording, documentary or
other taxes and any other fees and similar taxes which become payable in
connection with the Merger other than transfer or stamp taxes payable in respect
of transfers pursuant to Section 3.2(d)(i) (collectively, "Transfer Taxes").
From and after the Effective Date, Parent shall pay or cause to be paid, without
deduction or withholding from any amounts payable to the holders of Company
Common Stock, all Transfer Taxes.
 
                                   ARTICLE IV
                         REPRESENTATIONS AND WARRANTIES
 
    The Company represents and warrants to Parent and Sub as follows:
 
    Section 4.1.  ORGANIZATION, STANDING AND POWER.  Each of the Company and its
Subsidiaries is a corporation duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization, has all requisite
corporate power and authority to own, lease and operate its properties and to
carry on its business, including those subsidiaries engaged in the insurance
business (the "Insurance Subsidiaries"), as now being conducted, and is duly
qualified and in good standing to do business in each jurisdiction in which the
nature of its business or the ownership or leasing of its properties makes such
qualification necessary except when the failure to be so qualified would not
have a Material Adverse Effect on the Company. As used in this Agreement,
"Material Adverse Effect" means, when used with respect to Parent, Sub or the
Company, as the case may be, any change or effect, either individually or in the
aggregate, that is or may be materially adverse to the business, assets,
liabilities, properties, condition (financial or otherwise) or results of
operations of all or any part of Parent and its Subsidiaries taken as a whole,
Sub, or the Company and its Subsidiaries taken as a whole, as the case may be
(PROVIDED, HOWEVER, that in respect of the Company any such change or effect
relating to (i) PCA Property and Casualty Insurance Company, a Florida
corporation and a wholly-owned subsidiary of the Company ("P&C"), (ii) PCA
Solutions, Inc., a Florida corporation and a wholly-owned subsidiary of the
Company, or (iii) risk contracts between P&C or any of its Subsidiaries and the
Company's Florida HMOs regarding provision of health care services with respect
to worker's compensation as set forth on SCHEDULE 4.1, shall in each case be
excluded from such determination).
 
    Section 4.2.  CAPITAL STRUCTURE.  As of the date hereof, the authorized
capital stock of the Company consists of 200,000,000 shares of the Company
Common Stock and 10,000,000 shares of preferred stock, $1.00 par value ("Company
Preferred Stock"). At the close of business on May 30, 1997: (i) 38,837,657
shares of Company Common Stock were outstanding, 5,314,108 shares of Company
Common Stock were reserved for issuance upon the exercise of outstanding stock
options (3,119,950 shares of which are subject to outstanding stock options) or
pursuant to the Company's option plans, (ii) no shares of Company Common Stock
were reserved for issuance upon exercise of the Company's rights (the "Company
Rights") granted under the Rights Agreement, dated January 13, 1995 (the
"Company Rights Agreement"), between the Company and the Rights Agent (as
defined therein); (iii) no shares of Company Common Stock were held by its
wholly-owned Subsidiaries; (iv) no shares of the Company Preferred Stock were
 
                                      A-5
<PAGE>
outstanding; and (v) except as set forth on SCHEDULE 4.2, no warrants, bonds,
debentures, notes or other indebtedness or other security having the right to
vote (or convertible into or exercisable for securities having the right to
vote) on any matters on which stockholders may vote ("Voting Debt") were issued
or outstanding; since May 30, 1997 there has been no change in such share
information except by reason of the exercise of Options. All outstanding shares
of the Company capital stock are validly issued, fully paid and nonassessable
and not subject to preemptive rights. As of the date of this Agreement, except
for this Agreement, the Options and the Company Rights, there are no options,
warrants, calls, rights, or agreements to which the Company or any Subsidiary of
the Company is a party or by which it or any such Subsidiary is bound obligating
the Company or any Subsidiary of the Company to issue, deliver or sell, or cause
to be issued, delivered or sold, any shares of capital stock or any Voting Debt
of the Company or of any Subsidiary of the Company or obligating the Company or
any Subsidiary of the Company to grant, extend or enter into any such option,
warrant, call, right or agreement. Assuming compliance by Parent with Section
3.4 after the Effective Date, there will be no option, warrant, call, right or
agreement obligating the Company or any Subsidiary of the Company to issue,
deliver or sell, or cause to be issued, delivered or sold, any shares of capital
stock or any Voting Debt of the Company or any Subsidiary of the Company, or
obligating the Company or any Subsidiary of the Company to grant, extend or
enter into any such option, warrant, call, right or agreement.
 
    Section 4.2A.  SUBSIDIARIES.  The only Subsidiaries of the Company are
disclosed in SCHEDULE 4.2A. Each Significant Subsidiary (as such term is defined
in Rule 1-02 of Regulation S-X under the Securities Act of 1933, as amended (the
"Securities Act") of the Company has been named in the Company SEC Documents (as
hereinafter defined). SCHEDULE 4.2A contains, with respect to each Subsidiary of
the Company, its name and jurisdiction of incorporation and, with respect to
each Subsidiary that is not wholly owned, the number of issued and outstanding
shares of capital stock and the number of shares of capital stock owned by the
Company or a Subsidiary. All the outstanding shares of capital stock of each
Subsidiary of the Company are validly issued, fully paid and nonassessable, and
those owned by the Company or by a Subsidiary of the Company are owned free and
clear of any security interests, pledges, options, rights of first refusal,
liens, claims, encumbrances or any other limitation or restriction (including a
restriction on the right to vote or sell the same except as may be provided as a
matter of law). Except as set forth in SCHEDULE 4.2A, there are no existing
options, warrants, calls or other rights, agreements or commitments of any
character relating to the issued or unissued capital stock or other securities
of any of the Subsidiaries of the Company. Except as set forth in the Company's
Annual Report on Form 10-K for the fiscal year ended December 31, 1996 (the
"1996 Form 10K") and as disclosed in SCHEDULE 4.2A, the Company does not
directly or indirectly own any interest in any other corporation, partnership,
joint venture or other business association or entity.
 
    Section 4.3.  AUTHORITY.  The Company has all requisite corporate power and
authority to enter into this Agreement and subject to approval of this Agreement
and the Merger by the stockholders of the Company, to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement
and the consummation of the transactions contemplated hereby have been duly
authorized by all necessary corporate action on the part of the Company, subject
to such approval of this Agreement by the stockholders of the Company. This
Agreement has been duly executed and delivered by the Company and, subject to
such approval of this Agreement by the stockholders of the Company, constitutes
a valid and binding obligation of the Company enforceable against it in
accordance with its terms. The execution and delivery of this Agreement does
not, and the consummation of the transactions contemplated hereby will not,
conflict with, or result in any violation of, or default (with or without notice
or lapse of time, or both) under, or give rise to a right of termination,
cancellation or acceleration of any obligation or the loss of a material benefit
under, or the creation of a lien, pledge, security interest or other encumbrance
on assets (any such conflict, violation, default, right of termination,
cancellation or acceleration, loss or creation, a "Violation"), pursuant to any
provision of the Certificate of Incorporation or By-laws of the Company or any
Subsidiary of the Company or ,except as set forth on SCHEDULE 4.3 hereto, result
in
 
                                      A-6

any Violation of any loan or credit agreement, note, mortgage, indenture, lease,
Designated Plan (as hereinafter defined) or other agreement, obligation,
instrument, permit, concession, franchise, license, judgment, order, decree,
statute, law, ordinance, rule or regulation applicable to the Company or any
Subsidiary of the Company or their respective properties or assets which
Violation would have a Material Adverse Effect on the Company. No consent,
approval, order or authorization of, or registration, declaration or filing
with, any court, administrative agency or commission or other governmental
authority or instrumentality, domestic or foreign (a "Governmental Entity"), is
required by or with respect to the Company or any of its Subsidiaries in
connection with the execution and delivery of this Agreement by the Company, or
the consummation by the Company of the transactions contemplated hereby, the
failure to obtain which would have a Material Adverse Effect on the Company,
except for (i) the filing of a premerger notification report by the Company
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the
"HSR Act"), (ii) the filing with the Securities and Exchange Commission (the
"SEC") of (x) a proxy statement (the "Proxy Statement") in definitive form

Parent a true and complete copy of each material report, schedule, registration
statement and definitive proxy statement filed by the Company with the SEC since

material respects with applicable accounting requirements and with the published
rules and regulations of the SEC with respect thereto, have been prepared in
accordance with generally accepted accounting principles ("GAAP") applied on a

<PAGE>
consistent basis during the periods involved (except as may be indicated in the

10-Q) and fairly present in all material respects (subject, in the case of the

for the periods then ended.

    Section 4.6.  COMPLIANCE WITH APPLICABLE LAWS.  Except as set forth on
SCHEDULE 4.6, the businesses of the Company and each of its Subsidiaries have
been and are being conducted in compliance in all material respects with all
applicable laws, rules, ordinances, regulations, licenses, judgments, orders or
decrees of federal, state, local and foreign governmental authorities, except
for possible violations which individually or in the aggregate do not, and,
insofar as reasonably can be foreseen, in the future will not, have a Material
Adverse Effect on the Company. The Company and each of its Subsidiaries hold all
certificates of authority, franchises, grants, permits, licenses, easements,
consents, certificates, variances, exemptions, orders and approvals from all
Governmental Entities (collectively, "Company Permits") which are necessary to
own, lease and operate the assets and properties they currently own, lease and
operate and to conduct their respective businesses and operations in the manner
heretofore conducted and as proposed to be conducted, except for those Company
Permits the absence of which would not have a Material Adverse Effect on the
Company. SCHEDULE 4.6 contains a list of all Company Permits the violation of
which would have a Material Adverse Effect on the Company, including the
jurisdictions in which the Company or one or more of its Subsidiaries holds a
license or are otherwise authorized to conduct insurance business and the types
or lines of insurance which the Company or one or more of its Subsidiaries is
permitted to write in such jurisdictions. Except as set forth on SCHEDULE 4.6,
no notice has been received and, after due inquiry of management, no
investigation or review is pending or, to the Company's knowledge, threatened by
any Governmental Entity with regard to (i) any alleged violation by the Company
or any of its Subsidiaries of any law, rule, regulation, ordinance, Company
Permit, judgment, order or decree or (ii) any alleged failure to have or any
violation of any Company Permit, which violation or failure would have a
Material Adverse Effect on the Company. Neither the Company nor any of its
Subsidiaries nor to the Company's knowledge any of its or their respective
executive officers, directors or employees (in their capacities as such) has
engaged in any activity constituting fraud or abuse under the laws relating to
health care, insurance or the regulation of professional corporations.

1995, 1994, 1993, 1992, and the related audited consolidated statements of
operations, stockholders' equity/(deficit) and cash flows, for the fiscal years
ended on dates, together with all footnotes and (ii) the unaudited consolidated
interim financial statements for the Company and each of its Subsidiaries as at,
and for the fiscal periods ended on March 31, 1997 and each subsequent quarterly
reporting date. All of such financial statements fairly present or when
delivered will fairly present (subject, in the case of unaudited interim
financial statements, to normal, recurring adjustments which are not expected to
be, individually or in the aggregate, materially adverse to the Company and its
Subsidiaries taken as a whole), in all material respects, the financial
position, results of operations and cash flows of the Company and each of its
Subsidiaries as at the respective dates of such balance sheets and for each of
the respective periods then ended, in conformity with (A) GAAP and (B) in the
case of each of the Insurance Subsidiaries, statutory or other accounting
practices prescribed or permitted by the insurance regulatory
 
                                      A-8
<PAGE>
authorities in the States of Florida and Texas or in Puerto Rico, as
appropriate, in each case applied on a basis consistent throughout the reported
periods.
 
    (ii) Except as set forth on SCHEDULE 4.7, neither such financial statements
nor the financial statements of the Company included in the Company SEC
Documents (A) contain or when delivered will contain, as the case may be, any
item of extraordinary or non-recurring income or expense (except as specified
therein), (B) reflect or when delivered will reflect, as the case may be,
uncollectible accounts receivable without a reserve fairly stated for
uncollectible amounts, and (C) reflect or when delivered will reflect, as the
case may be, any write-off or revaluation of assets (except as specified
therein). As at the respective dates of the balance sheets included in all such
financial statements, there was no liability, indebtedness or obligation of any
nature or in any amount that should properly be reflected or provided for in
financial statements prepared in conformity with GAAP or statutory accounting
practices prescribed or permitted by the applicable insurance regulatory

or other accounting practices prescribed or permitted by the applicable
insurance regulatory authorities and of all the jurisdictions in which the
Insurance Subsidiaries are licensed to transact an insurance business and make
good and sufficient provisions for all insurance obligations of the Company and
its Subsidiaries. Such reserves have been opined upon as reasonable and adequate
as of December 31, 1996, by Towers Perrin Integrated Health Systems Consulting,
a duly qualified actuarial firm that, as of the date of its report, was a member
in good standing in the American Academy of Actuaries. The unpaid loss and loss
adjustment expense liabilities of P&C as of December 31, 1996, has been opined

or agreement with any labor union or organization. There are no pending or, to
the Company's knowledge, threatened, representation campaigns, elections or

employees, any demands for recognition or collective bargaining, any strikes,
slowdowns, work stoppages or lock-outs of any kind, or threats thereof, by or
with respect to any employees of the Company or any of its Subsidiaries, and no
such activities, efforts, demands, strikes, slowdowns, work stoppages or
lock-outs occurred during a three-year period preceding the date hereof. Neither

been held in any administrative or judicial proceeding to have committed any
unfair labor practice under the National Labor Relations Act, as amended. Except

transactions contemplated by this Agreement by any employee, officer or director
of the Company or a Controlled Company who is a "disqualified individual" (as
such term is defined in proposed Treasury Regulation Section 1.280G-1) under any
employment, severance or termination agreement, other compensation arrangement
or Designated Plan currently in effect would be characterized as an "excess
parachute payment" (as such term is defined in Section 280G(b)(1) of the Code).

its Insurance Subsidiaries nor, to the Company's knowledge, any other party

effect of which singly or in the aggregate would not have a Material Adverse
Effect on the Company, and none of such agreements contains any provision (A)
providing that any other party thereto may terminate such agreement or declare a
default or seek damages thereunder by reason of the transactions contemplated by
this Agreement or (B) which would be altered or otherwise become applicable by
reason of such transactions. The Company does not know of any facts or events

inclusion or incorporation by reference in the Proxy Statement and each
amendment or supplement thereto, at the time of mailing thereof and at the time
of the Company Meeting, will contain an untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading. For purposes of the foregoing, it is understood and agreed
that information concerning or related to Parent
 
                                      A-21
<PAGE>
will be deemed to have been supplied by Parent and information concerning or
related to the Company and the Company Meeting shall be deemed to have been
supplied by the Company. The Company will provide Parent with a reasonable
opportunity to review and comment on any amendment or supplement to the Proxy
Statement prior to filing such with the SEC, and will provide Parent with a copy
of all such filings made with the SEC. No amendment or supplement to the
information supplied by Parent for inclusion in the Proxy Statement shall be
made without the approval of Parent, which approval shall not be unreasonably
withheld or delayed.
 
    Section 7.3.  COMPANY STOCKHOLDER APPROVAL.  The Company will use its best
efforts to obtain the necessary approvals by its stockholders of the Merger,
this Agreement and the transactions contemplated hereby.
 
    Section 7.4.  EMPLOYEE MATTERS.  (a) The employees of the Company and each
Subsidiary as of the Effective Date shall continue employment with the Surviving
Corporation and the Subsidiaries, respectively, in the same positions and at the
same level of wages and/or salary and without having incurred a termination of
employment or separation from service; PROVIDED, HOWEVER, that the foregoing
shall not constitute any commitment, contract, understanding or guarantee
(express or implied) on the part of the Surviving Corporation of a
post-Effective Date employment relationship of any term or duration or on any
terms other than those the Surviving Corporation may establish. Employment of
any of the employees by the Surviving Corporation shall be "at will" and may be
terminated by the Surviving Corporation at any time for any reason (subject to
any legally binding agreement, or any applicable laws or any arrangement or
commitment); PROVIDED, FURTHER, that no provision of this Agreement shall create
any third-party beneficiary with respect to any employee (or dependent thereof)
of the Company or any of its Subsidiaries in respect of continued employment or
resumed employment. As of the Effective Date, the Surviving Corporation shall be
the sponsor of the Company's option plans immediately prior to the Effective
Date, and Parent shall cause the Surviving Corporation and the Subsidiaries to
satisfy all obligations and liabilities under such option plans. Until at least
December 31, 1997, Parent shall maintain employee benefits and programs for
officers and employees of the Company and its Subsidiaries that are no less
favorable in the aggregate than those being provided to such officers and
employees on the date hereof (it being understood that Parent will not be
obligated to continue any one or more employee benefits or programs). To the
extent any employee benefit plan, program or policy of the Parent or its
affiliates is made available to the employees of the Surviving Corporation or
its Subsidiaries, (i) service with the Company and its Subsidiaries by any
employee prior to the Effective Date shall be credited for eligibility and
vesting purposes under such plan, program or policy, but not for benefit accrual
purposes, and (ii) with respect to any welfare benefit plans to which such
employees may become eligible, Parent shall cause such plans to provide credit
for any co-payments or deductibles by such employees and waive all pre-existing
condition exclusions and waiting periods, other than limitations or waiting
periods that have not been satisfied under any welfare plans maintained by the
Company and the Subsidiaries for their employees prior to the Effective Date.
Parent shall honor or cause to be honored all severance and employment
agreements with the Company's officers and employees to the extent disclosed in
the Schedules to this Agreement.
 
    Section 7.5.  INDEMNIFICATION.  (a) From and after the Effective Date,
Parent shall indemnify, defend and hold harmless the officers, directors and
employees of the Company and its subsidiaries who were such at any time prior to
the Effective Date (the "Indemnified Parties") from and against all losses,
expenses, claims, damages or liabilities arising out of the transactions
contemplated by this Agreement to the fullest extent permitted or required under
applicable law, including without limitation the advancement of expenses. Parent
agrees that all rights to indemnification existing in favor of those persons
provided for in the Company's Certificate of Incorporation or By-Laws, as in
effect as of the date hereof, with respect to matters occurring through the
Effective Date, shall survive the Merger and shall continue in full force and
effect for a period of not less than six years from the Effective Date. Parent
agrees to cause the Surviving Corporation to maintain in effect for not less
than six years after the Effective Date the current policies of
 
                                      A-22
<PAGE>
directors' and officers' liability insurance maintained by the Company with
respect to matters occurring on or prior to the Effective Date; PROVIDED,
HOWEVER, that the Surviving Corporation may substitute therefor policies of at
least the same coverage (with carriers comparable to the Company's existing
carriers) containing terms and conditions which are no less advantageous to the
Indemnified Parties; PROVIDED, FURTHER, that Parent shall not be required in
order to maintain or procure such coverage to pay an annual premium in excess of
150% of the current annual premium paid by the Company for its existing coverage
(the "Cap"); and PROVIDED, FURTHER, that if equivalent coverage cannot be
obtained, or can be obtained only by paying an annual premium in excess of the
Cap, Parent shall only be required to obtain as much coverage as can be obtained
by paying an annual premium equal to the Cap.
 
    (b) Any Indemnified Party will promptly notify the Parent and the Surviving
Corporation of any claim, action, suit, proceeding or investigation for which
such party may seek indemnification under this Section; PROVIDED, HOWEVER, that
the failure to furnish any such notice shall not relieve Parent or the Surviving
Corporation from any indemnification obligation under this Section except to the
extent Parent or the Surviving Corporation is materially prejudiced thereby. In
the event of any such claim, action, suit, proceeding, or investigation, (x)
Parent or the Parent and Surviving Corporation will have the right to assume the
defense thereof, and Parent and the Surviving Corporation will not be liable to
such Indemnified Parties for any legal expenses of other counsel or any other
expenses subsequently incurred thereafter by such Indemnified Parties in
connection with the defense thereof, except that all Indemnified Parties (as a
group) will have the right to retain one separate counsel, reasonably acceptable
to such Indemnified Party and Parent, at the expense of the indemnifying party
if the named parties to any such proceeding include both the Indemnified Party
and the Surviving Corporation and the representation of such parties by the same
counsel would be inappropriate due to a conflict of interest between them, (y)
the Indemnified Parties will cooperate in the defense of any such matter, and
(z) the Surviving Corporation will not be liable for any settlement effected
without its prior written consent.
 
    Section 7.6.  BEST EFFORTS.  Upon the terms and subject to the conditions
set forth in this Agreement, each of the parties agrees to use its best efforts
to take, or cause to be taken, all actions, and to do, or cause to be done, and
to assist and cooperate with the other parties in doing, all things necessary,
proper or advisable to consummate and make effective, in the most expeditious
manner practicable, the Merger, and the other transactions contemplated by this
Agreement, including (a) promptly making their respective filings and thereafter
making any other required submission under the HSR Act, (b) diligently opposing
any objections to, appeals from or petitions to reconsider or reopen any such
approval by persons not a party to this Agreement, (c) the obtaining of all
necessary actions or non-actions, waivers, consents and approvals from
Governmental Entities and the making of all necessary registrations and filings
(including filings with Governmental Entities) and the taking of all reasonable
steps as may be necessary to obtain an approval or waiver from, or to avoid an
action or proceeding by any Governmental Entity, (d) the obtaining of all
necessary consents, approvals or waivers from third parties, (e) the defending
of any lawsuits or other legal proceedings, whether judicial or administrative,
challenging this Agreement or the consummation of the transactions contemplated
hereby, including seeking to have any stay or temporary restraining order
entered by any court or other Governmental Entity vacated or reversed, and (f)
the execution and delivery of any additional instruments necessary to consummate
the transactions contemplated by this Agreement; PROVIDED, HOWEVER, that the
Company and Parent shall not be under any obligation to take any action to the
extent that their respective Board of Directors shall conclude in good faith,
after consultation with their respective outside counsel, that such action could
be inconsistent with such Board of Director's fiduciary obligations under
applicable law and, PROVIDED FURTHER, that in satisfying their obligations set
forth above neither Parent nor Sub shall be obligated to dispose or to agree to
dispose any assets of either Parent or the Company or their respective
Subsidiaries, nor shall Parent or Sub be required to agree to any conditions as
a prerequisite to obtaining any such approvals (other than any conditions that
are ministerial in nature or are customary for transactions of a similar
nature).

    Section 7.7.  PUBLIC ANNOUNCEMENTS.  Parent and Sub, on the one hand, and
the Company, on the other hand, will consult with each other before issuing any
press release or otherwise making any public statements with respect to the
transactions contemplated by this Agreement, and shall not issue any such press
release or make any such public statement prior to such consultation, except as
may be required by applicable law or by obligations pursuant to any listing
agreement with any national securities exchange.
 
    Section 7.8.  ALTERNATIVE PROPOSALS.  Prior to the Effective Date, the
Company agrees: (a) that neither it nor any of its Subsidiaries shall, and it
shall direct and use its best efforts to cause its officers, directors,
employees, agents and representatives (including, without limitation, any
investment banker, attorney or accountant retained by it or any of its
Subsidiaries) not to, initiate, solicit or encourage, directly or indirectly,
any inquiries or the making or implementation of any proposal or offer
(including, without limitation, any proposal or offer to its stockholders) with
respect to a merger, acquisition, consolidation or similar transaction
involving, or any purchase of all or any significant portion of the assets or
any equity securities of, the Company or any of its Subsidiaries (any such
proposal or offer being hereinafter referred to as an "Alternative Proposal") or
engage in any negotiations concerning, or provide any confidential information
or data to, or have any discussions with, any person relating to an Alternative
Proposal, or release any third party from any obligations under any existing
standstill agreement or arrangement relating to any Alternative Proposal, or
otherwise facilitate any effort or attempt to make or implement an Alternative
Proposal; (b) that it will immediately cease and cause to be terminated any
existing activities, discussions or negotiations with any parties conducted
heretofore with respect to any of the foregoing, and it will take the necessary
steps to inform the individuals or entities referred to above of the obligations
undertaken in this Section 7.8; and (c) that it will notify Parent immediately
if any such inquiries or proposals are received by, any such information is
requested from, or any such negotiations or discussions are sought to be
initiated or continued with, it; PROVIDED, HOWEVER, that nothing contained in
this Section 7.8 shall prohibit the Board of Directors of the Company from
furnishing information to any person or entity that makes an Alternative
Proposal, if, and only to the extent that, (A) the Board of Directors of the
Company determines in good faith after consultation with outside counsel that
such action is required for the Board of Directors to comply with its fiduciary
duties to stockholders imposed by law, (B) the Alternative Proposal is a
Superior Proposal, (C) the Company provides Parent with a true and complete copy
of such proposal as soon as practicable after the receipt thereof, and (D) to
the extent applicable, complying with Rule 14e-2 promulgated under the Exchange
Act with regard to an Alternative Proposal. Nothing in this Section 7.8 shall
(x) permit the Company to terminate this Agreement (except as specifically
provided in Article IX hereof), (y) permit the Company to have discussions,
negotiations or to enter into any agreement with respect to an Alternative
Proposal during the term of this Agreement (it being agreed that during the term
of this Agreement, the Company shall not enter into any discussion, negotiation
or agreement with any person that provides for, or in any way facilitates, an
Alternative Proposal (other than a confidentiality agreement in customary
form)), or (z) affect any other obligation of the Company under this Agreement.
As used in this Agreement, a "Superior Proposal" means a bona fide written offer
to acquire the Company pursuant to a merger, consolidation, share exchange,
purchase of a substantial portion of assets, business combinations or other
similar transaction (which offer shall not be subject to any conditions that are
more onerous to the Company than the conditions to Parent and Sub's obligations
to consummate the Merger; provided, however, that such offer may be subject to
confirmatory due diligence to be effected within a five (5) business day
period): (i) that the Board of Directors of the Company determines, in good
faith after consultation with a nationally recognized investment banking firm
which provided a written opinion to such effect, provides a higher value per
share to the stockholders of the Company than the Merger Consideration after
taking into account, among other things, the reasonable likelihood the Effective
Date will occur as compared to when the closing of such Alternative Proposal
will occur; (ii) that is not subject to any financing condition (and the offeror
has on hand funds available or committed financing to consummate the offer and
the transactions contemplated; thereby); (iii) does not have any condition to
closing or rights to terminate more onerous to the Company than the
 
                                      A-24
<PAGE>
provisions set forth in Articles VIII or IX hereof; and (iv) does not involve
any substantive legal impediments that are reasonably likely to prevent such
Alternative Proposal from closing.
 
    Section 7.9.  ADVICE OF CHANGES; SEC FILINGS.  The Company shall confer on a
regular basis with Parent on operational matters. Parent and the Company shall
promptly advise each other orally and in writing of (i) any change or event that
has had, or could reasonably be expected to have, a Material Adverse Effect on
Parent or the Company, as the case may be, (ii) any litigation or governmental
complaints, investigation or hearings (or communication indicating that the same
may be contemplated), or (iii) the breach in any material respect of any
representation or warranty contained herein. The Company and Parent shall
promptly provide each other (or their respective counsel) copies of all filings
made by such party with the Commission or any other Governmental Entity in
connection with this Agreement and the transactions contemplated hereby.
 
    Section 7.10.  FEE AND EXPENSES.  Whether or not the Merger is consummated,
all costs and expenses incurred in connection with this Agreement and the
transactions contemplated hereby shall be paid by the party incurring such costs
and expenses, except as provided in Section 9.5.
 
    Section 7.11.  AMENDMENT TO THE COMPANY RIGHTS AGREEMENT.  The Company, in
accordance with the terms and provisions of the Company Rights Agreement and as
promptly as practicable on or after the date hereof, shall amend the Company
Rights Agreement so as to exclude the Merger and the transaction contemplated by
this Agreement from the Company Rights Agreement.
 
    Section 7.12.  P&C COMMITMENTS.  (a) Parent and Sub shall (i) on and
following the Effective Date, perform or discharge all obligations of the
Company not previously performed and discharged pursuant to those certain
agreements by and between the Company and Center Reinsurance Company of New York
set forth on SCHEDULE 7.12 hereto (the "Centre Re Agreements") or (ii) in lieu
of such performance or discharge, shall enter into an alternative arrangement
satisfactory to the State of Florida, ex rel, The Department of Insurance (the
"Department").
 
    (b) At the Closing, Parent agrees to perform one of the following actions:
(x) to make (i) a capital contribution to P&C of an amount equal to the
statutory deficit of P&C as of the Closing and (ii) to commit to make additional
contributions, from time to time, in order to remove any statutory deficits
thereafter incurred by P&C; (y) to pay the closing premium required, and cause
PCA and it's subsidiaries to perform all of their obligations, under the terms
of the Centre Re Agreements; or (z) to enter into such other arrangements as the
Department, in its sole discretion, determines is acceptable.
 
    Section 7.13.  ASSUMPTION OF DEBT OBLIGATIONS.  Sub shall assume or repay
all debt obligations of the Company on the Effective Date.
 
    Section 7.14.  ESCROW DEPOSIT.  (a) Simultaneously with the execution of
this Agreement, Parent made a $15 million payment (the "Escrow Deposit") into an
escrow account established by the Department for the benefit of P&C, the terms
of which account are set forth in Schedule 7.14. In consideration of making such
payment, the Company hereby grants Parent the right (the "Option") to purchase
for $0.01 per share a number of shares of Company Common Stock equal to $15
million divided by 70% of the average closing prices of the Company Common Stock
for the five trading days immediately prior to the exercise of the Option (as
such prices are reported by the NASD National Market System or such other
principal trading market on which the Company Common Stock then trades).
Parent's right to exercise the Option is subject to (a) the termination of this
Agreement (the "Termination"), (b) the Escrow Deposit not having been returned
to Parent and (c) the obtaining by Parent of all required governmental and
regulatory approvals for such purchase of Company Common Stock. The Option is
exercisable in whole upon 90 days prior written notice to the Company, provided
that the Option may be exercised from time to time in part to the extent Parent
is unable to acquire all of the remaining shares of Company Common Stock subject
to the Option by reason of governmental or regulatory approvals. Parent's right
to give notice
 
                                      A-25
<PAGE>
of exercise of the Option shall expire upon the later of (i) six months
following the Termination or (ii) 30 days after receipt of all required
governmental or regulatory approvals.
 
    (b) The Company represents and warrants to Parent that the shares of Common
Stock issuable upon exercise of the Option shall be validly issued, fully paid
and non-assessable.
 
    (c) In lieu of issuing any shares of Company Common Stock subject to the
Option, the Company may, prior to the exercise of any part of the Option, cancel
the Option by paying to the Company the sum of $15 million plus interest from
the date of execution of this Agreement to the date of payment at a rate per
annum of 10%.
 
    (d) Upon the issuance of any shares of Company Common Stock, the Company
shall file a registration statement with the Securities and Exchange Commission
(the "Commission") covering such shares of Company Common Stock and any other
shares of Company Common Stock to be issued thereafter pursuant to the Option.
The Company shall use its best efforts to cause the Commission to declare the
registration statement effective and cause the registration statement to remain
effective for two years thereafter. The Company will assist Parent in effecting
an underwritten offering, upon customary terms and conditions, with respect to
such shares of Company Common Stock with an underwriter of national standing
selected by Parent.

fiduciary duties to stockholders of the Board of Directors of the Company; (ii)
five business days shall have elapsed after delivery to Parent of a written
notice by the Company informing Parent that the Board of Directors of the

<PAGE>
in good faith with the intent of enabling Parent to agree to a modification of
the terms and conditions of this Agreement (including the Merger Consideration)
so that the Alternative Proposal would not constitute a Superior Proposal as
compared to the terms and conditions of this Agreement as proposed to be
modified by Parent (the "Modified Agreement"); and (iii) at the end of such five

stockholders;
 
    (b) There has been a breach by the Company of any representation or warranty
contained herein which has had, or would be reasonably expected to have, a
Material Adverse Effect on the Company and which breach has not been cured
within five (5) business days following receipt by the Company of notice of such
breach; or
 
    (c) There has been a material breach of any of the covenants or agreements
set forth in this Agreement on the part of the Company, which breach is not

    Section 9.5.  EFFECT OF TERMINATION AND ABANDONMENT.  (a) In the event that
(i) (x) any person shall have made an Alternative Proposal and thereafter this
Agreement is terminated either by the Company pursuant to Section 9.3(a) or by
either party pursuant to Section 9.2(b) or (y) the Board of Directors of the
Company shall have withdrawn or modified in a manner adverse to Parent its
approval or recommendation of this Agreement or the Merger or shall have
recommended an Alternative Proposal to the Company stockholders and Parent shall
have terminated this Agreement pursuant to Section 9.4(a), then the Company
shall promptly, but in no event later than two days after such termination, pay
Parent a fee of $17 million, plus documented out-of-pocket expenses incurred by
Parent in connection with the transactions completed hereby not to exceed $1.5
million (collectively, the "Payment") or (z) this Agreement is terminated for
any reason other than those set forth in clauses (x) or (y) above (other than
pursuant to Section 9.3(b) or (c)), and if within 12 months thereafter any
Alternative Proposal shall have been consummated, then the Company shall
promptly, but in no event later than two days after consummation of any such
transaction, pay Parent the lessor of (i) the Payment and (ii)(a) 3.5% of the
sum of the following: (A) the consideration paid to the Company stockholders
pursuant to such Alternative Proposal, (B) the principal amount of any debt
outstanding on the date such Alternative Proposal is consummated, and (C) the
amount paid or agreed to be paid to the Department in connection with the
matters contemplated by the Forebearance Agreement or any amendments or
supplements thereto plus
 
                                      A-28
<PAGE>
(b) documented out-of-pocket expenses incurred by Parent in connection with the
transactions contemplated hereby not to exceed $1.5 million; PROVIDED, HOWEVER,
that no payment shall be made to Parent under clause (z) above if the Agreement
is terminated pursuant to Section 9.2(a) and, at the time of the termination,
the only condition to closing not satisfied was the condition set forth in
Section 8.1(b), 8.1(c), 8.1(d) or 8.1(e)(or any combination thereof). Any amount
payable hereunder shall be payable by wire transfer of same day funds. The
Company acknowledges that the agreements contained in this Section 9.5(a) are an
integral part of the transactions contemplated in this Agreement, and that,
without these agreements, Parent and Sub would not enter into this Agreement;
accordingly, if the Company fails to promptly pay the amount due pursuant to
this Section 9.5(a), and, in order to obtain such payment, Parent or Sub
commences a suit which results in a judgment against the Company for the fee set

Board of Directors
 
Physician Corporation of America
 
6101 Blue Lagoon Drive
 
Miami, Florida 33126
 
Dear Sirs:
 
    We understand that Physician Corporation of America ("PCA") and Humana Inc.
("Humana") have entered into an Agreement and Plan of Merger dated as of June 2,
1997 (the "Merger Agreement"), pursuant to which a newly-formed, wholly-owned
subsidiary of Humana ("Humana Acquisition Corp.") will merge with and into PCA,
with each outstanding share of common stock of PCA, par value $0.01, being
converted into and representing the right to receive $7.00 in cash (the
"Transaction").
 
    You have asked us to render our opinion as to whether the Transaction is
fair, from a financial point of view, to the stockholders of PCA.
 
    In the course of performing our review and analyses for rendering this
opinion, we have:
 
    1.  reviewed the Merger Agreement, dated June 2, 1997;
 
    2.  reviewed PCA's Annual Reports to Shareholders and Annual Reports on Form
       10-K for the years ended December 31, 1994 through 1996 and PCA's
       Quarterly Report on Form 10-Q for the period ended March 31, 1997;
 
    3.  reviewed certain operating and financial information provided to us by
       the management of PCA relating to its business and prospects, including
       financial projections as of May 3, 1997, provided to us by PCA's
       management;
 
    4.  met with certain members of the senior management of PCA to discuss
       PCA's operations, historical financial statements, future prospects and
       financial condition;
 
                                      B-1

                                                                         ANNEX B
 
    Board of Directors
 
    August 8, 1997
 
    Page 2
 
    5.  met with certain members of the Department of Insurance for the State of
       Florida ("DOI") to discuss the regulatory implications of the financial
       status of PCA Property & Casualty Insurance Company ("P&C"), including
       the possibility of having P&C placed into receivership;
 
    6.  met with certain members of the senior management of PCA to discuss the
       impact on PCA of having P&C placed into receivership;
 
    7.  visited PCA's facilities in Miami, Florida and Orlando, Florida;
 
    8.  reviewed the historical stock prices, trading activity and valuation
       parameters of the PCA Common Stock;
 
    9.  reviewed publicly available financial data, stock market performance
       data and valuation parameters of companies which we deemed generally
       comparable to PCA;
 
    10. reviewed the terms of recent mergers and acquisitions of companies which
       we deemed generally comparable to the Transaction; and
 
    11. considered and conducted such other studies, analyses, inquiries and
       investigations as we deemed appropriate.
 
    In the course of our review, we have relied upon and assumed the accuracy
and completeness of the financial, regulatory and other information provided to
us by PCA and others. With respect to the projections provided to us by PCA, we
determined not to rely on certain of the internal estimates of PCA's future
financial performance in our analyses because of, among other things, the
inherent uncertainty of such projections and the fact that actual results for
fiscal 1996 differed materially from past projections for such periods for PCA;
with your consent we also considered estimates made by security analysts (other
than ourselves) in reports published in the last six months. We have not assumed
any responsibility for the information or projections provided to us and we have
further relied upon the assurances of the management of PCA that they are
unaware of any facts that would make the information or projections provided to
us incomplete or misleading.
 
    In arriving at our opinion, we have not performed, obtained or been
furnished with any independent appraisal of the assets or liabilities of PCA.
This letter does not address PCA's underlying decision to pursue the
Transaction. Our opinion is necessarily based on economic, market and other
conditions, and the information made available to us, as of the date hereof.
 
    Based on the foregoing, it is our opinion that the Transaction is fair, from
a financial point of view, to the stockholders of PCA.

Board of Directors

    We have acted as financial advisor to PCA in connection with the Transaction
and will receive a fee for such services, payment of a significant portion of
which is contingent upon the consummation of the Transaction. In addition, in
the past we have acted as financial advisor to PCA, have provided investment
banking services to PCA, and we have been paid fees for such services.
 
    It is understood that this letter is intended for the benefit and use of the
Board of Directors of PCA and does not constitute a recommendation to the
stockholders of PCA as to how to vote on the Transaction. This letter may be
included in its entirety in any proxy statement or other document distributed to
stockholders of PCA in connection with the solicitation of proxies in favor of
the Transaction (but any reference to or description of the opinion expressed
herein in any such proxy statement or other document or any other public
reference to this letter shall be subject to our prior written consent). This
letter is not to be used for any other purpose, or reproduced, disseminated,
quoted or referred to at any time, in whole or in part, without our prior
written consent.

                     GENERAL CORPORATION LAW OF DELAWARE


Section 262. Appraisal Rights. 

     (a) Any stockholder of a corporation of this State who holds shares of 
stock on the date of the making of a demand pursuant to subsection (d) of 
this section with respect to such shares, who continuously holds such shares 
through the effective date of the merger or consolidation, who has otherwise 
complied with subsection (d) of this section and who has neither voted in 
favor of the merger or consolidation nor consented thereto in writing 
pursuant to Section  228 of this title shall be entitled to an appraisal by 
the Court of Chancery of the fair value of his shares of stock under the 
circumstances described in subsections (b) and (c) of this section.  As used 
in this section, the word "stockholder" means a holder of record of stock in 
a stock corporation and also a member of record of a nonstock corporation; 
the words "stock" and "share" mean and include what is ordinarily meant by 
those words and also membership or membership interest of a member of a 
nonstock corporation; and the words "depository receipt" mean a receipt or 
other instrument issued by a depository representing an interest in one or 
more shares, or fractions thereof, solely of stock of a corporation, which 
stock is deposited with the depository. 
 
     (b) Appraisal rights shall be available for the shares of any class or 
series of stock of a constituent corporation in a merger or consolidation to 
be effected pursuant to Section  251 (other than a merger effected pursuant 
to subsection (g) of Section 251), 252, 254, 257, 258, 263 or 264 of this 
title: 

           (1) Provided, however, that no appraisal rights under this section 
     shall be available for the shares of any class or series of stock, which 
     stock, or depository receipts in respect thereof, at the record date 
     fixed to determine the stockholders entitled to receive notice of and to 
     vote at the meeting of stockholders to act upon the agreement of merger 
     or consolidation, were either (i) listed on a national securities 
     exchange or designated as a national market system security on an 
     interdealer quotation system by the National Association of Securities 
     Dealers, Inc. or (ii) held of record by more than 2,000 holders; and 
     further provided that no appraisal rights shall be available for any 
     shares of stock of the constituent corporation surviving a merger if the 
     merger did not require for its approval the vote of the holders of the 
     surviving corporation as provided in subsection (f) of Section 251 of 
     this title. 

          (2) Notwithstanding paragraph (1) of this subsection, appraisal 
     rights under this section shall be available for the shares of any class 
     or series of stock of a constituent corporation if the holders thereof 
     are required by the terms of an agreement of merger or consolidation 
     pursuant to Sections 251, 252, 254, 257, 258, 263 and 264 of this title 
     to accept for such stock anything except: 

               a. Shares of stock of the corporation surviving or resulting 
          from such merger or consolidation, or depository receipts in 
          respect thereof; 

               b. Shares of stock of any other corporation, or depository 
          receipts in respect thereof, which shares of stock or depository 
          receipts at the effective date of the merger or consolidation will 
          be either listed on a national securities exchange or designated as 
          a national market system security on an interdealer quotation 
          system by the National Association of Securities Dealers, Inc. or 
          held of record by more than 2,000 holders; 

               c. Cash in lieu of fractional shares or fractional depository 
          receipts described in the foregoing subparagraphs a. and b. of this 
          paragraph; or 

               d. Any combination of the shares of stock, depository receipts 
          and cash in lieu of fractional shares or fractional depository 
          receipts described in the foregoing subparagraphs a., b. and c. of 
          this paragraph.  

                                      D-1

          (3) In the event all of the stock of a subsidiary Delaware 
     corporation party to a merger effected under Section  253 of this title 
     is not owned by the parent corporation immediately prior to the merger, 
     appraisal rights shall be available for the shares of the subsidiary 
     Delaware corporation. 

     (c) Any corporation may provide in its certificate of incorporation that 
appraisal rights under this section shall be available for the shares of any 
class or series of its stock as a result of an amendment to its certificate 
of incorporation, any merger or consolidation in which the corporation is a 
constituent corporation or the sale of all or substantially all of the assets 
of the corporation. If the certificate of incorporation contains such a 
provision, the procedures of this section, including those set forth in 
subsections (d) and (e) of this section, shall apply as nearly as is 
practicable. 
 
     (d) Appraisal rights shall be perfected as follows: 
 
          (1) If a proposed merger or consolidation for which appraisal 
     rights are provided under this section is to be submitted for approval 
     at a meeting of stockholders, the corporation, not less than 20 days 
     prior to the meeting, shall notify each of its stockholders who was such 
     on the record date for such meeting with respect to shares for which 
     appraisal rights are available pursuant to subsection (b) or (c) hereof 
     that appraisal rights are available for any or all of the shares of the 
     constituent corporations, and shall include in such notice a copy of 
     this section. Each stockholder electing to demand the appraisal of his 
     shares shall deliver to the corporation, before the taking of the vote 
     on the merger or consolidation, a written demand for appraisal of his 
     shares. Such demand will be sufficient if it reasonably informs the 
     corporation of the identity of the stockholder and that the stockholder 
     intends thereby to demand the appraisal of his shares. A proxy or vote 
     against the merger or consolidation shall not constitute such a demand. 
     A stockholder electing to take such action must do so by a separate 
     written demand as herein provided. Within 10 days after the effective 
     date of such merger or consolidation, the surviving or resulting 
     corporation shall notify each stockholder of each constituent 
     corporation who has complied with this subsection and has not voted in 
     favor of or consented to the merger or consolidation of the date that 
     the merger or consolidation has become effective; or  

          (2) If the merger or consolidation was approved pursuant to Section 
      228 or Section  253 of this title, each constituent corporation, either 
     before the effective date of the merger or consolidation or within ten 
     days thereafter, shall notify each of the holders of any class or series 
     of stock of such constituent corporation who are entitled to appraisal 
     rights of the approval of the merger or consolidation and that appraisal 
     rights are available for any or all shares of such class or series of 
     stock of such constituent corporation, and shall include in such notice 
     a copy of this section; provided that, if the notice is given on or 
     after the effective date of the merger or consolidation, such notice 
     shall be given by the surviving or resulting corporation to all such 
     holders of any class or series of stock of a constituent corporation 
     that are entitled to appraisal rights. Such notice may, and, if given on 
     or after the effective date of the merger or consolidation, shall, also 
     notify such stockholders of the effective date of the merger or 
     consolidation. Any stockholder entitled to appraisal rights may, within 
     twenty days after the date of mailing of such notice, demand in writing 
     from the surviving or resulting corporation the appraisal of such 
     holder's shares. Such demand will be sufficient if it reasonably informs 
     the corporation of the identity of the stockholder and that the 
     stockholder intends thereby to demand the appraisal of such holder's 
     shares. If such notice did not notify stockholders of the effective date 
     of the merger or consolidation, either (i) each such constituent 
     corporation shall send a second notice before the effective date of the 
     merger or consolidation notifying each of the holders of any class or 
     series of stock of such constituent corporation that are entitled to 
     appraisal rights of the effective date of the merger or consolidation or 
     (ii) the surviving or resulting corporation shall send such a second 
     notice to all such holders on or within 10 days after such effective 
     date; provided, however, that if such second notice is sent more than 20 
     days following the sending of the first notice, such second notice need 
     only be sent to each stockholder who is entitled to appraisal rights and 
     who has demanded appraisal of such holder's shares in accordance with 
     this subsection. An affidavit of the secretary or assistant secretary or 
     of the transfer agent of the corporation that is required to give either 
     notice that such notice has been given shall, in the absence of fraud, 
     be prima 

                                      D-2

     facie evidence of the facts stated therein. For purposes of determining 
     the stockholders entitled to receive either notice, each constituent 
     corporation may fix, in advance, a record date that shall be not more 
     than 10 days prior to the date the notice is given; provided, that if 
     the notice is given on or after the effective date of the merger or 
     consolidation, the record date shall be such effective date. If no 
     record date is fixed and the notice is given prior to the effective 
     date, the record date shall be the close of business on the day next 
     preceding the day on which the notice is given. 
 
     (e) Within 120 days after the effective date of the merger or 
consolidation, the surviving or resulting corporation or any stockholder who 
has complied with subsections (a) and (d) hereof and who is otherwise 
entitled to appraisal rights, may file a petition in the Court of Chancery 
demanding a determination of the value of the stock of all such stockholders. 
Notwithstanding the foregoing, at any time within 60 days after the effective 
date of the merger or consolidation, any stockholder shall have the right to 
withdraw his demand for appraisal and to accept the terms offered upon the 
merger or consolidation. Within 120 days after the effective date of the 
merger or consolidation, any stockholder who has complied with the 
requirements of subsections (a) and (d) hereof, upon written request, shall 
be entitled to receive from the corporation surviving the merger or resulting 
from the consolidation a statement setting forth the aggregate number of 
shares not voted in favor of the merger or consolidation and with respect to 
which demands for appraisal have been received and the aggregate number of 
holders of such shares. Such written statement shall be mailed to the 
stockholder within 10 days after his written request for such a statement is 
received by the surviving or resulting corporation or within 10 days after 
expiration of the period for delivery of demands for appraisal under 
subsection (d) hereof, whichever is later. 
 
     (f) Upon the filing of any such petition by a stockholder, service of a 
copy thereof shall be made upon the surviving or resulting corporation, which 
shall within 20 days after such service file in the office of the Register in 
Chancery in which the petition was filed a duly verified list containing the 
names and addresses of all stockholders who have demanded payment for their 
shares and with whom agreements as to the value of their shares have not been 
reached by the surviving or resulting corporation. If the petition shall be 
filed by the surviving or resulting corporation, the petition shall be 
accompanied by such a duly verified list. The Register in Chancery, if so 
ordered by the Court, shall give notice of the time and place fixed for the 
hearing of such petition by registered or certified mail to the surviving or 
resulting corporation and to the stockholders shown on the list at the 
addresses therein stated. Such notice shall also be given by 1 or more 
publications at least 1 week before the day of the hearing, in a newspaper of 
general circulation published in the City of Wilmington, Delaware or such 
publication as the Court deems advisable. The forms of the notices by mail 
and by publication shall be approved by the Court, and the costs thereof 
shall be borne by the surviving or resulting corporation. 
 
     (g) At the hearing on such petition, the Court shall determine the 
stockholders who have complied with this section and who have become entitled 
to appraisal rights. The Court may require the stockholders who have demanded 
an appraisal for their shares and who hold stock represented by certificates 
to submit their certificates of stock to the Register in Chancery for 
notation thereon of the pendency of the appraisal proceedings; and if any 
stockholder fails to comply with such direction, the Court may dismiss the 
proceedings as to such stockholder. 
 
     (h) After determining the stockholders entitled to an appraisal, the 
Court shall appraise the shares, determining their fair value exclusive of 
any element of value arising from the accomplishment or expectation of the 
merger or consolidation, together with a fair rate of interest, if any, to be 
paid upon the amount determined to be the fair value. In determining such 
fair value, the Court shall take into account all relevant factors. In 
determining the fair rate of interest, the Court may consider all relevant 
factors, including the rate of interest which the surviving or resulting 
corporation would have had to pay to borrow money during the pendency of the 
proceeding. Upon application by the surviving or resulting corporation or by 
any stockholder entitled to participate in the appraisal proceeding, the 
Court may, in its discretion, permit discovery or other pretrial proceedings 
and may proceed to trial upon the appraisal prior to the final determination 
of the stockholder entitled to an appraisal. Any stockholder whose name 
appears on the list filed by the surviving or resulting corporation pursuant 
to subsection (f) of this section and who has submitted his certificates of 
stock to the Register in Chancery, if such is required, may participate fully 
in all proceedings until it is finally determined that he is not entitled to 
appraisal rights under this section. 
 
     (i) The Court shall direct the payment of the fair value of the shares, 
together with interest, if any, by the surviving or resulting corporation to 
the stockholders entitled thereto. Interest may be simple or compound, as the 

                                      D-3
<PAGE>

Court may direct. Payment shall be so made to each such stockholder, in the 
case of holders of uncertificated stock forthwith, and the case of holders of 
shares represented by certificates upon the surrender to the corporation of 
the certificates representing such stock. The Court's decree may be enforced 
as other decrees in the Court of Chancery may be enforced, whether such 
surviving or resulting corporation be a corporation of this State or of any 
state. 
 
     (j) The costs of the proceeding may be determined by the Court and taxed 
upon the parties as the Court deems equitable in the circumstances. Upon 
application of a stockholder, the Court may order all or a portion of the 
expenses incurred by any stockholder in connection with the appraisal 
proceeding, including, without limitation, reasonable attorney's fees and the 
fees and expenses of experts, to be charged pro rata against the value of all 
the shares entitled to an appraisal. 
 
     (k) From and after the effective date of the merger or consolidation, no 
stockholder who has demanded his appraisal rights as provided in subsection 
(d) of this section shall be entitled to vote such stock for any purpose or 
to receive payment of dividends or other distributions on the stock (except 
dividends or other distributions payable to stockholders of record at a date 
which is prior to the effective date of the merger or consolidation); 
provided, however, that if no petition for an appraisal shall be filed within 
the time provided in subsection (e) of this section, or if such stockholder 
shall deliver to the surviving or resulting corporation a written withdrawal 
of his demand for an appraisal and an acceptance of the merger or 
consolidation, either within 60 days after the effective date of the merger 
or consolidation as provided in subsection (e) of this section or thereafter 
with the written approval of the corporation, then the right of such 
stockholder to an appraisal shall cease. Notwithstanding the foregoing, no 
appraisal proceeding in the Court of Chancery shall be dismissed as to any 
stockholder without the approval of the Court, and such approval may be 
conditioned upon such terms as the Court deems just. 
 
     (l) The shares of the surviving or resulting corporation to which the 
shares of such objecting stockholders would have been converted had they 
assented to the merger or consolidation shall have the status of authorized 
and unissued shares of the surviving or resulting corporation.
