COMPENSATION OF THE BOARD OF DIRECTORS
 
  In 1997, Directors who were not employees of the Company were paid an annual
retainer fee of $38,000 for serving on the Board of Directors plus an
attendance fee of $2,000 per regular and special meeting. Each non-employee
member of the Executive Committee received an additional $5,000 annually. Each
committee chairperson was paid an annual amount of $3,000. Committee members
received no additional compensation for their service on committees or for
attending committee meetings.
 
  In 1997, in connection with his position as Vice Chairman of the Board,
David A. Jones, Jr. also received an annual fee of $100,000 and $30,000 as
reimbursement for office expenses. Mr. Jones, Jr. also was granted options for
40,000 Shares of Company Common Stock which are included in the totals below.
 
  The Company matches, on an annual basis, up to $20,000 in charitable
contributions made by each Non-employee Director.
 
  The Company provides each Non-employee Director with group life and
accidental death insurance in the amount of $100,000, business travel accident
insurance in the amount of $250,000 and pays certain local taxes on their
behalf.
 
  The Company also maintains the 1989 Stock Option Plan for Non-employee
Directors (the "Directors Stock Plan") pursuant to which options to purchase
15,000 Shares of the Common Stock are granted at 100% of the fair market value
to each Non-employee Director upon his or her initial election to the Board of
Directors. In addition, options to purchase 5,000 Shares of the Common Stock
are granted on the first business day of each January at 100% of the fair
market value to each Non-employee Director who has been a director
continuously for at least the full calendar year prior thereto.
 
                                       3

  In 1997, total awards under the Company stock option plans were as follows:

</TABLE>
 
  Effective January 1, 1998, no new director will receive any retirement
benefits. The current directors, listed herein, will be grandfathered under
the Company's Retirement Policy (the "Policy"). The Policy provides that a
director who is not an employee must retire at the annual meeting following
his or her seventy-third birthday. The retiring director is entitled to elect
to receive either (i) an annual retirement benefit for the life of the
director in the amount of $38,000, the annual retainer fee in effect for 1997;
or (ii) in lieu thereof, an actuarially equivalent joint and survivor annuity
payment. In addition, each retiring director also receives an annual matching
charitable contribution benefit of 50% of the annual retirement benefit.
Benefits are prorated for any retiring director who has not served at least
ten years on the Board of Directors. Currently, the Company is paying benefits
under the Policy to two former directors and has a separate letter agreement
with one other former director that was executed prior to the adoption of the
Policy. The benefits under the letter agreement are comparable to those under
the Policy.
 
  Also, effective January 1, 1998, the directors' compensation structure was
changed. The Chairman of the Board will receive a $200,000 annual cash
retainer and will not receive attendance fees. In 1998, the Vice Chairman will
receive $30,000 as reimbursement for office expenses, and, in addition to the
annual director stock option award, has been granted an option to purchase
40,000 Shares of Company Common Stock. All other members, including the Vice
Chairman, will receive, as a portion of the annual retainer, 1,000 Shares of
Company Common Stock on the first business day of each January, a cash payment
equal to 30% of the fair market value of the 1,000 Shares of Company Common
Stock issued, plus a $10,000 annual cash retainer. See "Proposal 2: Approval
of the Amendments to the Company's 1989 Stock Option Plan for Non-employee
Directors" below.
 
  All other components (i.e., meeting fees, committee fees, stock options,
matching charitable contributions and insurance) were unchanged and are
described above.
 
PROPOSAL 2: APPROVAL OF THE AMENDMENTS TO THE COMPANY'S 1989 STOCK OPTION PLAN
                          FOR NON-EMPLOYEE DIRECTORS
 
  Effective January 1998, the Board of Directors amended the Directors'
compensation to include an equity portion in order to more closely align the
directors' and stockholders' interests. New York Stock Exchange Regulations
require stockholder approval of issuance of Company Common Stock to directors,
unless treasury shares are used. In January 1998, each Non-employee Director
(except the Chairman) received a 1,000 share award from the Company's treasury
shares.
 
  The Board of Directors believes that in order to attract and retain the
services of experienced and knowledgeable Non-employee Directors and to
encourage them to devote their utmost effort and skill to the advancement and
betterment of the Company, Non-employee Directors should participate in the
ownership of the Company.
 
  If approved by stockholders, it is intended that each Non-employee Director
(except the Chairman) would receive 1,000 Shares of Company Common Stock (or
such other number as approved by the Board of Directors) on the first business
day of each January thereafter. The Shares of Company Common Stock could come
from treasury shares or, after stockholder approval, those Shares of Company
Common Stock set aside for the Directors Stock Plan.
 
  In 1989 the Board of Directors approved and in 1990 the stockholders adopted
the Directors Stock Plan. The Directors Stock Plan was amended in 1993 and
1994 with stockholder approval. In 1996, when the stockholders approved the
adoption of the Company's 1996 Plan, the number of Shares of Company Common
 
                                       4
<PAGE>
 
Stock remaining for future grant under the Directors Stock Plan was set at
150,000. At March 1, 1998, 85,000 Shares of Company Common Stock remained
under the Directors Stock Plan and the Company had 8,899 treasury shares
remaining. The Board of Directors recommends the approval of 80,000 additional
Shares of Company Common Stock under the Directors Stock Plan.
 
  The following summary of the material terms of the Directors Stock Plan does
not purport to be complete and is qualified in its entirety by the terms of
the Directors Stock Plan, a copy of which is attached hereto as Exhibit A.
Terms not defined herein shall have the same meaning as in the Plan.
 
ELIGIBILITY
 
  Directors of the Company who are not employees of the Company are eligible
to participate in the Directors Stock Plan.
 
OPTIONS/AWARDS
 
  The Directors Stock Plan provides that each Non-employee Director is granted
an option to purchase 15,000 Shares of Company Common Stock on the date the
Non-employee Director is initially elected or appointed to the Board of
Directors. In addition to the initial grant, each Non-employee Director who
has served as such for one full year prior thereto is granted an option to
purchase 5,000 Shares of Company Common Stock on the first business day of
each January. The per share exercise price of each such option is 100% of the
Fair Market Value as of the grant date. The options vest in full one year from
date of grant. The options granted under the Directors Stock Plan are not
intended to be incentive stock options.
 
  Upon approval of the stockholders, Non-employee Directors may be permitted
or required, subject to the policies and procedures established by the
Organization & Compensation Committee of the Board of Directors, as approved
by the full Board of Directors, to receive Shares of Company Common Stock at
Fair Market Value in lieu of cash payment of all or a portion of their fees
for serving as a director and attending Board of Director and committee
meetings.
 
NUMBER OF AUTHORIZED SHARES OF COMPANY COMMON STOCK
 
  Subject to the approval of stockholders, the maximum number of Shares of
Common Stock for which stock options may be granted or which may be awarded in
lieu of all or a portion of the annual retainer under the Directors Stock Plan
will be increased by 80,000 bringing the total number available for future
awards to 165,000. The Shares of Common Stock to be delivered under the
Directors Stock Plan will be made available from the authorized but unissued
Shares of Common Stock or from treasury shares. The number and class of shares
available under the Directors Stock Plan and/or subject to outstanding options
may be adjusted by the Board of Directors to prevent dilution or enlargement
of rights in the event of various changes in the capitalization of the
Company.
 
ADMINISTRATION
 
  The Directors Stock Plan will be administered by the Organization &
Compensation Committee of the Board of Directors. Subject to the provisions of
the Directors Stock Plan, the Committee shall be authorized to interpret the
Directors Stock Plan, to establish, amend, and rescind any rules and
regulations relating thereto and to make all other determinations necessary or
advisable for its administration. The determinations of the Committee in the
administration of the Directors Stock Plan, as described herein, shall be
final and conclusive. The Secretary of the Company shall be authorized to
implement the Directors Stock Plan, in accordance with its terms and to take
such actions of a ministerial nature as shall be necessary to effectuate the
intent and purposes thereof. The validity, construction and effect of the
Directors Stock Plan and any rules and regulations relating thereto shall be
determined in accordance with the laws of the State of Delaware.
 
TRANSFERABILITY
 
  Shares of Company Common Stock issued under the Directors Stock Plan in
respect of the annual retainer may be assigned or transferred, while options
granted under the Directors Stock Plan are not transferable.

TERM OF THE PLAN
 
  The Directors Stock Plan currently would expire in May 1999 and stockholders
are being requested to extend the term. Upon approval by stockholders, no
option may be granted or Shares of Company Common Stock awarded under the
Directors Stock Plan after the tenth anniversary of the approval by Company's
stockholders at the Annual Meeting held on May 14, 1998.
 
AMENDMENTS
 
  The Directors Stock Plan may be amended by the Company's Board of Directors,
as it shall deem advisable or to conform to any change in any law or
regulation applicable thereto.
 
FEDERAL INCOME TAX CONSEQUENCES
 
  Directors who receive Shares of Company Common Stock as payment of all or a
portion of the annual retainer, will recognize ordinary income at that time
equal to the Fair Market Value of such Shares of Company Common Stock received
(less the price paid for the Shares of Company Common Stock). The Company will
be entitled to a deduction for federal income tax purposes of an equal amount
at that time.
 
  Any long- or short-term gain or loss realized by a Director on disposition
of the Shares of Company Common Stock acquired under the Directors Stock Plan
will be taxed to such Director, and will not result in any additional tax
consequences to the Company. The Director's basis in the Shares of Company
Common Stock for determining gain or loss on the disposition will generally be
the Fair Market Value of such Shares of Company Common Stock at the time of
the award.

(1) All options granted are non-qualified except for 13,239 incentive stock
    options granted to Mr. Wolf. These options have vesting periods ranging
    from one year to three years following the date of grant, and expire ten
    years after the date of grant. The options become exercisable in equal
    installments. The exercise price per share was equal to the fair market
    value of the Common Stock on the date of grant. In the event of a Change in
    Control of the Company, all outstanding stock options become fully vested
    and immediately exercisable in their entirety. In addition, during the 60-
    day period following the Change in Control, any stock option (or portion
    thereof) may generally be surrendered for cancellation for a payment of the
    difference between the market and option price as more fully described in
    the 1996 Plan.
 
(2) The exercise price may be paid in cash or, at the discretion of the
    Organization & Compensation Committee, in Shares of Company Common Stock
    valued at fair market value on the date immediately preceding the date of
    exercise, or any combination thereof.
 
(3) The dollar amounts in this table represent the potential realizable value
    of the stock options granted, assuming that the market price of the Shares
    of Company Common Stock appreciate in value from the date of grant to the
    end of the option term at annualized rates of 5% and 10%. Therefore, these
    amounts are not the actual value of the options granted and are not
    intended to forecast possible future appreciation, if any, of Company
    Common Stock prices. No assurances can be given that the stock price will
    appreciate at these rates or experience any appreciation at all.

  Under the OTRP, the benefits will be based on salary and incentive
compensation. The maximum years of service credited under the OTRP, unless
otherwise changed by the Board of Directors, is 30 years. Mr. Jones was given
credit for his actual years of service. For 36 years of service, upon his
retirement on December 1, 1997, Mr. Jones received a benefit as described
below under "Certain Agreements." The years of service for each of the other
Named Executive Officers are as follows: Gregory H. Wolf--9; Karen A.
Coughlin--18; Michael B. McCallister--24; Jerry D. Reeves, M.D.--1; and
Kenneth J. Fasola--8; Messrs. Wolf and Fasola were credited for their years of
service with EFG.
 
CERTAIN AGREEMENTS
 
  On December 1, 1997, Mr. Jones retired as Chief Executive Officer of the
Company. At that time, Mr. Jones relinquished his employment agreement with
the Company. In consideration of Mr. Jones' continued commitment to the
Company in completing the transition of management, in leading the Company
through a period of strategic change, and in recognition of his long and
distinguished career as a co-founder of the Company, the Organization &
Compensation Committee, with the consent of the other disinterested Directors,
awarded him a one-time cash payment of $2,500,000, which amount is included in
the Summary Compensation Table.
 
  Upon his retirement, Mr. Jones received distributions of certain vested
benefits accumulated during the course of his years of service with the
Company. In that regard he received a benefit from the OTRP in the form of an
annuity payment for his lifetime and the lifetime of his spouse, should he
predecease her. The OTRP provides Mr. Jones a monthly benefit of $60,006. Mr.
Jones received $535,078 from the Company's Thrift Excess Plan and $3,240,246
from the Company's Supplemental Executive Retirement Plan. He also received a
distribution from the Humana Retirement and Savings Plan of 270,604 Shares of
Company Common Stock, reflecting the accumulation of his own contributions and
the Company's match over his years of service.
 
  As the Company's Chairman of the Board of Directors, Mr. Jones will receive
an annual retainer of $200,000. The retainer will also replace any attendance
fees he would otherwise be paid. In addition to Board of Directors'
responsibilities, Mr. Jones' compensation reflects his continuing consultation
on major initiatives of the Company and on corporate strategy and policy, and
his external activities, including preserving and enhancing the image of the
Company within the health care industry. He will be eligible for other fees
and benefits that are provided to outside members of the Board of Directors as
described in this Proxy Statement under "Compensation of the Board of
Directors."
 
  Mr. Jones will also be provided office space, with an annual value of
approximately $43,500 and administrative and secretarial support with an
annual value of approximately $150,000.
 
  The Company will continue to provide the benefits and arrangements described
above to Mr. Jones for at least as long as he serves as Chairman of the Board.
 
  In December 1997, the Company entered into an agreement with Mr. Wolf
pursuant to which he i) serves as President and Chief Executive Officer of the
Company at an annual base salary not less than his base salary at the
effective date of the agreement, ii) participates in an incentive plan
providing for a target incentive compensation amount of not less than 100% of
his base salary and iii) shall be eligible for participation in all benefit
plans and programs made available by the Company for its executive employees.
In the event of termination of employment without Good Cause (as defined in
the agreement), pursuant to disability or death, the Company will pay to him
or his estate an amount equal to his base salary plus bonus calculated at 100%
of his base salary. He is also entitled to continued coverage for a 12-month
period under the Company's life, health and disability plans upon the same
terms and costs for other employees of the Company. Additionally, all
restricted shares shall become vested and all stock options shall become fully
vested and shall be exercisable for a two-year period following his
termination.
 
  In the event of termination of employment with Good Cause, other than for
performance reasons, Mr. Wolf would receive an amount equal to his then
current base salary earned but not yet paid and shall have a period of 90 days
to exercise any vested options. Mr. Wolf would forfeit any unvested options or
restricted shares.
 
                                      17
<PAGE>
 
  In the event of termination of employment i) because either the Company or
Mr. Wolf gives notice of termination of the agreement, ii) because the Company
terminates his employment for performance reasons, or iii) because Mr. Wolf
voluntarily terminates his employment during the Employment Period, then the
Company shall pay to him an amount equal to his base salary. Any bonus payable
shall be prorated. He is also entitled to continued coverage for a 12-month
period under the Company's life, health and disability plans upon the same
terms and costs for other similarly situated employees of the Company.
 
  In the event of termination of employment following a Change in Control, as
defined in the agreement, Mr. Wolf shall receive i) his full base salary earned
but not yet paid through the termination date at the greater of the rate in
effect at the time of the Change in Control or the Termination Date (Higher
Annual Base Salary), plus any incentive compensation which has been earned, ii)
an amount equal to two and one-half times the amount equal to the sum of the
Higher Annual Base Salary plus the maximum target incentive compensation which
could have been earned, and iii) continued coverage for a two-year period, at
the Company's expense, under all life, health, dental, accidental death and
dismemberment and disability insurance.
 
  All officers duly elected by the Board of Directors, including the Named
Executive Officers, generally receive health benefits upon termination for
themselves and their eligible dependents at a predetermined rate until the
earlier of attainment of age 65 or obtaining other coverage.
 
  The Company has entered into agreements with all other officers, including
the Named Executive Officers, and key management employees which for a two-year
period following a Change in Control provide certain benefits upon termination.
Such termination shall be involuntary or shall be due to a resignation as a
result of a change in responsibilities or compensation. Pursuant to the
agreements, these individuals would be entitled to receive severance pay which
generally is determined by multiplying the sum of each individual's annual base
salary, and the maximum incentive compensation payable to him or her, by a
multiple ranging from one to one and one-half.
 
  In addition, in the event of a Change in Control of the Company, benefits are
payable under the Company's Stock Option Plans, and health, life and disability
insurance coverage is available.
 
                CERTAIN TRANSACTIONS WITH MANAGEMENT AND OTHERS
 
  In 1994, the Company entered into an agreement with JAPC, Inc. ("JAPC"),
which is owned by David A. Jones. Pursuant to such agreement, the Company
provides hangar space, pilot services and maintenance for an airplane owned by
JAPC, and the Company may also use the JAPC pilots to fly Company-owned
aircraft. The rate paid for the hangar space is at least as favorable to the
Company as market rates for comparable space. The Company is fully reimbursed
for the cost of airplane maintenance. The agreement generally may be terminated
by either party upon 30 days' written notice. For the fiscal year ended
December 31, 1997, pursuant to the agreement, the Company was reimbursed by
JAPC $50,795.
 
  In 1995, the Company completed a commitment to invest $1 million in The
African-American Venture Capital Fund, Inc., a Kentucky Limited Liability
Company ("Fund"). This investment makes the Company a greater than 10%
stockholder of the Fund. David A. Jones made a similar investment in the Fund
and is a director, officer and greater than 10% stockholder of the Fund. The
Fund was established to provide capital and management resources to enhance the
growth and development of businesses owned by African-Americans living in the
metropolitan Louisville, Kentucky area.
 
  In August 1997, the Company loaned Michael B. McCallister, Senior Vice
President, $250,000, with interest at 8.50%, to assist him in moving from the
Company's Louisville, Kentucky office to its Florida Regional office. The
largest amount outstanding during the 1997 fiscal year was $258,442, the amount
outstanding at December 31, 1997.

                  ORGANIZATION & COMPENSATION COMMITTEE REPORT
 
EXECUTIVE OFFICER COMPENSATION POLICY
 
  The Organization & Compensation Committee (the "Committee") administers the
Company's executive officer compensation plan, the key components of which are
base salary, incentive compensation, stock option and restricted stock awards.
Each member of the Committee is an independent Non-employee Director who has
never been an employee of the Company.
 
  The executive officer compensation plan rewards executive officers for short
and long-term performance. In addition to base salary, executive officers are
compensated on a performance-oriented basis through the use of incentive
compensation linking both short and long-term results. One component, the
annual incentive bonus, permits team and individual performance to be
recognized on an annual basis and is based, in part, on an evaluation of the
contribution made by the officer to Company performance. Stock options are
included in the compensation plan to reward executive officers for longer-term
strategic actions which increase Company value. This use of stock options
directly relates a significant portion of each executive officer's long-term
remuneration to the Company's stock price, and thus aligns the executive's
compensation with the interest of the Company's other stockholders. The
granting of stock options as well as the limited use of restricted stock is
intended to: (1) recognize promotions of executives into positions of
significant responsibilities, (2) recognize significant accomplishments of
executives, particularly those that impact growth, profits and/or competitive
positioning, and (3) provide additional incentive to attract and retain high
level executive talent. The Committee uses outside consultants to assist it in
evaluating the various components of executive officer compensation.
 
  The executive officer compensation plan is designed to allow the Company to
be competitive in the marketplace in attracting, motivating and retaining key
executive officers. The marketplace is defined as both (1) publicly traded
companies approximating the Company's revenue and employee size, including
certain high performing companies, and (2) specific companies in the Managed
Care Industry. Because of mergers in the Managed Care Industry, the Company
uses a health care index in its Stock Performance Graph instead of a specific
peer group. The Committee believes this definition of the marketplace provides
a good benchmark for analyzing the competitiveness of the Company's executive
compensation plan. The Committee considers the overall compensation package
when setting any one component of compensation.
 
  Effective December 1, 1997, David A. Jones, the Company's Co-Founder,
Chairman, and Chief Executive Officer, retired as an executive officer of the
Company. Mr. Jones will continue as a Non-employee Chairman of the Board of
Directors. Concurrently, the Board of Directors elected Gregory H. Wolf, the
Company's President and Chief Operating Officer, to the position of President
and Chief Executive Officer.
 
BASE COMPENSATION
 
  Base compensation for executive officers was determined by an assessment of
overall company performance, executive officer performance, and changes in
executive officer responsibilities. While many aspects of performance can be
measured in financial terms, the Committee also evaluates senior management in
areas of performance which are more subjective. These areas include the
development and execution of strategic plans, which address, among other
issues, the delivery of quality medical care and customer service, the exercise
of leadership in the development of management and associates, innovation and
improvement in the Company's products and processes, plus executive involvement
in industry groups and in the communities that the Company serves.
 
INCENTIVE COMPENSATION
 
  The Company's incentive compensation plans are designed to reward officers
and designated key associates for the attainment of financial goals and other
performance objectives approved annually by the Committee. During 1997, the
Company had two incentive compensation plans which covered its executive
officers. The Humana Inc. Executive Management Incentive Compensation Plan--
Group A, based solely on the attainment of pre-established Company consolidated
net income objectives, with maximum potential payments of 100% of
 
                                       19
<PAGE>
 
base pay, covered Messrs. Jones and Wolf. All other executive officers,
including the Named Executive Officers, were covered by the Company's 1997
Management Incentive Plan, which based awards on the attainment of certain
earnings and growth goals for 1997 with maximum potential payments ranging
from 25% to 100% of base pay. The Company did not meet its goals under either
plan in 1997, and no incentive compensation was paid to these executive
officers under either plan.
 
  In January 1998, the Committee reviewed the Company's accomplishments during
1997 and determined, with the approval of the full Board of Directors, to
grant a discretionary bonus to key employees of the Company, including
executive officers. The dollar amount of the total discretionary bonus pool
for all key employees under this Plan was less than the amount that would have
been paid under the 1997 Management Incentive Plan had the Company achieved
its minimum goals for both earnings and growth. Mr. Wolf exempted himself from
receiving a discretionary bonus for his 1997 accomplishments and requested
that any discretionary bonus that would be paid to him be instead distributed
to other employees to increase their discretionary bonus opportunities under
this program. Amounts paid to the other Named Executive Officers are included
in the Summary Compensation Table.
 
STOCK OPTIONS/RESTRICTED STOCK AWARDS
 
  The Company uses stock options and restricted stock awards to reward
officers and key associates for long-term performance and as a method to
attract, motivate, and retain these key employees. The use of equity based
compensation provides a vital, long-term link between the results achieved for
the Company's stockholders and the rewards provided to executive officers and
other associates.
 
  All stock options are granted at the fair market value of the Company's
stock on the date of grant. The Committee, through review of stock programs at
comparable companies, determines, with the assistance of outside consultants,
the aggregate amounts, terms and timing of stock option and restricted stock
awards. The number of shares covered by each award reflects the executive's
level of responsibility along with past and anticipated future contributions
to the Company.
 
  In 1997, the Committee granted options and restricted stock totaling
approximately 1.78% of the Company's outstanding Common Stock. See "Chief
Executive Officer Compensation" below for a description of stock awards to
Messrs. Jones and Wolf. See "1997 Stock Option Grants" for a description of
stock options granted to the other Named Executive Officers.
 
CHIEF EXECUTIVE OFFICER COMPENSATION
 
  At the beginning of 1997, at the request of the Company's Board of Directors
and with the full approval and support of the Committee, David A. Jones, the
Company's Co-Founder, Chairman, and Chief Executive Officer continued to
postpone his retirement as Chief Executive Officer past his normal retirement
date of September 1, 1996. Mr. Jones agreed to continue to work with Mr. Wolf
in guiding the Company through the reorganization of its management team and
to work with the Board of Directors to identify his successor as Chief
Executive Officer. Both objectives were accomplished in 1997, culminating in
the naming of Mr. Wolf as the Company's President and Chief Executive Officer
effective December 1, 1997.
 
  In January 1997, Mr. Jones received an increase in base salary to
$1,012,440. He was also granted 170,000 stock options which vest in one year.
As discussed above, Mr. Jones did not receive any incentive compensation for
1997.
 
  In consideration of Mr. Jones' continued commitment to the Company in
completing the transition of management, in leading the Company through a
period of strategic change, and in recognition of his long and distinguished
career with the Company, the Committee awarded him a one-time cash payment of
$2,500,000 upon his retirement in December 1997. As the Company's Non-employee
Chairman of the Board of Directors, Mr. Jones will receive an annual retainer
of $200,000 plus certain office and secretarial support. The retainer
 
                                      20
<PAGE>
 
will also replace any attendance fees he would otherwise be paid. In addition
to Board of Directors' responsibilities, Mr. Jones' compensation reflects his
continuing consultation on major initiatives of the Company and on corporate
strategy and policy, and his external activities, including preserving and
enhancing the image of the Company within the Healthcare Industry nationwide
and in the communities it serves. He will be eligible for other fees and
benefits that are provided to outside members of the Board of Directors as
described in this Proxy Statement under "Compensation of the Board of
Directors."
 
  In January 1997, Mr. Wolf received an increase in base salary to $550,000.
He was also granted 150,000 stock options vesting ratably over a three-year
period. Mr. Wolf was elected as a member of the Company's Board of Directors
in September 1997. In December of 1997, upon his election as the Company's
President and Chief Executive Officer, his base salary was increased to
$800,000. Mr. Wolf received a retention bonus of $200,000 representing the
final payment due him in conjunction with the Company's merger with EMPHESYS
Financial Group, Inc. in October 1995. He was also granted 100,000 restricted
shares and 234,000 stock options both of which vest ratably over a three-year
period. As discussed above, Mr. Wolf did not receive any incentive
compensation for 1997. The Company also signed an Employment Contract with Mr.
Wolf which is more fully described in this Proxy Statement under "Executive
Compensation of the Company--Certain Agreements."
 
  The management succession of the Company culminating in the retirement of
Mr. Jones and the election of Mr. Wolf as Chief Executive Officer was an
unusual circumstance in the history of the Company. The Committee and the
Board of Directors utilized two independent outside compensation consulting
organizations to assist them in arriving at their compensation decisions
relative to Mr. Jones' retirement and Mr. Wolf's appointment as Chief
Executive Officer.

  The Omnibus Budget Reconciliation Act of 1993 amended the Internal Revenue
Code ("Code") to provide generally that compensation paid by publicly held
corporations to the chief executive officer and the four most highly paid
senior executive officers in excess of $1 million per year per executive will
be deductible by the Company only if paid pursuant to qualifying performance-
based compensation plans approved by stockholders of the Company. Compensation
as defined by the Code includes, among other things, base salary, incentive
compensation and gains on stock options and restricted stock. It is the
Committee's policy to maximize the effectiveness of the Company's executive
compensation plans. In that regard, the Committee intends to maintain
flexibility to take actions which it deems to be in the best interest of the
Company and its stockholders. Such actions may not always qualify for tax
deductibility under the Code. The Company believes it has taken the necessary
steps to qualify the Company's performance-based compensation plans for tax
deductibility. The Company also believes that all compensation paid for 1997
is deductible for federal income tax purposes.

            PROPOSAL 3: APPROVAL OF 1998 MANAGEMENT INCENTIVE PLAN
                           FOR EXECUTIVE MANAGEMENT
 
  In 1997, the Organization & Compensation Committee of the Board of Directors
(the "Committee") adopted the Humana Inc. 1998 Executive Management Incentive
Compensation Plan (the "1998 MIP"). Under Section 162(m) of the Code, the
amount of compensation paid to the Chief Executive Officer and the four other
most highly paid executive officers of the Company in the year for which a
deduction is claimed by the Company (including its subsidiaries) is limited to
$1,000,000 per person, except that compensation that is performance-based will
be excluded for purposes of calculating the amount of compensation subject to
this $1,000,000 limitation. The Company has structured the 1998 MIP so that
any compensation paid pursuant to the 1998 MIP will all be "performance-based
compensation" within the meaning of Section 162(m) of the Code.
 
  The principal provisions of the 1998 MIP are summarized below. This summary,
however, does not purport to be complete and is qualified in its entirety by
reference to the provisions of the 1998 MIP, a copy of which is attached
hereto as Exhibit B. Terms not defined herein shall have the same meaning as
set forth in the 1998 MIP.
 
  The Committee will administer the 1998 MIP and have final authority to
construe and interpret it. The Committee will annually select those executive
officers who shall be eligible to participate in the 1998 MIP and establish
benchmarks for the MIP objectives.
 
  Awards earned will be paid on or before March 15 following the close of the
calendar year in which they are earned based on the Participant's base salary
at the beginning of such calendar year.
 
  The Maximum Award for any Performance Period shall be equal to 125% of a
Participant's base salary paid, but shall not exceed $2,000,000.
 
  Gregory H. Wolf currently participates in an incentive compensation plan
approved by the Company's stockholders in 1994. If the 1998 MIP is approved by
stockholders, it is intended that Mr. Wolf will be the sole participant in
1999. Mr. Wolf would be eligible for a maximum bonus of 125% of his base
salary earned during that year. No other executive officer or employee is
currently expected to participate in the 1998 MIP. The Non-employee Directors
are not eligible to participate in the 1998 MIP.
 
  Approval of the 1998 MIP requires the affirmative vote of the holders of a
majority of the Shares of Company Common Stock represented at the Annual
Meeting, in person or by proxy, and entitled to vote.
 
  THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR
APPROVAL OF THE 1998 MIP.
 
 PROPOSAL 4: APPROVAL OF AMENDMENT TO INCREASE THE NUMBER OF AUTHORIZED SHARES
                         OF COMPANY COMMON STOCK UNDER
                  THE 1996 STOCK INCENTIVE PLAN FOR EMPLOYEES
 
  On March 14, 1996 and May 9, 1996 the Board of Directors and the
stockholders, respectively, adopted the Humana Inc. 1996 Stock Incentive Plan
for Employees (the "1996 Plan"). The 1996 Plan authorized the grant of
6,250,000 Shares of Company Common Stock. The Board of Directors believes that
in order to attract, retain and reward valuable personnel, including those
individuals joining the Company as part of the Company's acquisition efforts
and strategies, it is important for the Company to maintain a flexible, long-
term, stock-based incentive plan, which is both competitive with, and
responsive to, rapidly changing healthcare industry standards. The 1996 Plan
provides the Company with the ability to devise incentive programs which are
responsive to the demands of the marketplace without unduly diluting
stockholder interests.
 
  At March 24, 1998, there were 11,948,816 options outstanding and 26,816
Shares of Company Common Stock were available for future grants. Subject to
stockholder approval, the Company Board of Directors further amended the 1996
Plan to increase the total number of Shares of Company Common Stock for which
options could be granted to an amount not to exceed 4,400,000 additional
Shares of Company Common Stock.
 
                                      23
<PAGE>
 
  The 1996 Plan authorizes the grant of any of the following awards
(hereinafter "Employee Awards") to eligible participants: (i) stock options
which do not constitute "incentive stock options" within the meaning of
Section 422 of the Code ("nonqualified stock options"); (ii) incentive stock
options; and (iii) restricted shares. Employee Awards may be granted on a
stand-alone, combination or tandem basis.
 
  The principal provisions of the 1996 Plan are summarized below. This
summary, however, does not purport to be complete and is qualified in its
entirety by reference to the provisions of the 1996 Plan, a copy of which is
attached hereto as Exhibit C. Terms not defined herein shall have the same
meaning as set forth in the 1996 Plan.
 
PURPOSE
 
  The 1996 Plan is intended to provide incentives and rewards for employees
(i) to support the execution of the Company's business and human resource
strategies and the achievement of its goals and (ii) to associate the
interests of employees with those of the Company's stockholders.
 
ADMINISTRATION
 
  The 1996 Plan will be administered by the Organization & Compensation
Committee of the Board of Directors ("Committee"). In administering the 1996
Plan, the Committee will determine, among other things (i) the individuals to
whom grants of Employee Awards will be made; (ii) the type and size of
Employee Awards; and (iii) the terms of an Employee Award including, but not
limited to, vesting schedule, grant price, restriction or performance
criteria, and length of relevant performance, restriction or option period.
The Committee may also construe, interpret and correct defects, omissions and
inconsistencies in the 1996 Plan.
 
PARTICIPATION
 
  The Committee may grant Employee Awards under the 1996 Plan to any "Eligible
Individual." In practice, Employee Awards are made to a group of approximately
500 management employees. The Non-employee Directors are eligible, under
certain circumstances, to participate in the 1996 Plan.
 
SHARES OF COMPANY COMMON STOCK AVAILABLE FOR ISSUANCE
 
  The stock subject to the provisions of the 1996 Plan shall be authorized but
unissued Shares of Company Common Stock. The 1996 Plan initially provided for
6,250,000 Shares of Common Stock to be available for grant of Employee Awards.
As amended, subject to stockholder approval, 4,400,000 additional Shares of
Company Common Stock would be authorized. The total number of Shares of
Company Common Stock with respect to which Employee Awards may be granted to
any individual over the term of the Plan may not exceed 15% of the total
Shares of Company Common Stock authorized for the 1996 Plan. The total number
of Shares of Company Common Stock available for awards of Restricted Stock is
fifteen percent (15%) of the total Shares of Company Common Stock authorized
under the 1996 Plan. Pursuant to the 1996 Plan, the number and kind of Shares
of Company Common Stock to which Employee Awards are subject may be
appropriately adjusted in the event of certain changes in capitalization of
the Company, including stock dividends and splits, reclassification,
recapitalization, reorganizations, mergers, consolidations, spin-offs, split-
ups, combinations or exchanges of shares, and certain distributions, warrants
and repurchase of shares.
 
STOCK OPTIONS
 
  The Committee may grant stock options to Eligible Individuals in the form of
an incentive stock option or a nonqualified stock option. The exercise period
for any stock option granted will be determined by the Committee at the time
of grant but may not exceed ten years from the date of grant (five years in
the case of an Incentive Stock Option granted to a Ten-Percent Stockholder).
The exercise price per Share of Company Common Stock covered by a stock option
may not be less than 100% of the fair market value of a Share of Company
Common Stock on the date of grant (110% in the case of an incentive stock
option granted to a Ten-Percent Stockholder).
 
                                      24
<PAGE>
 
The exercise price is payable, at the Committee's discretion, in cash, in
shares of already owned Common Stock or in any combination of cash and shares.
Stock options shall become exercisable in installments as determined by the
Committee and set forth in the optionee's Agreement. Each option grant may be
exercised in whole, at any time, or in part, from time to time, after the
grant becomes exercisable.
 
  Unless the Committee determines otherwise, if a participant's employment
terminates by reason of death or disability, any outstanding stock options
will vest fully and be exercisable at any time within two years following the
date of death or disability (but in no event beyond the stated term of the
option in the case of an incentive stock option). Unless the Committee
determines otherwise, upon an optionee's retirement, stock options shall be
exercisable at any time prior to the end of the stated term date of the stock
option or two years following the retirement date, whichever is the shorter
period, but only to the extent the stock options are vested at retirement.
Unless the Committee determines otherwise, upon termination for any other
reason other than for cause, any previously vested stock options will be
exercisable for the lesser of 90 days or the balance of the stock option's
stated term. In the event of termination for cause, all options, whether or
not exercisable, shall terminate.
 
RESTRICTED SHARES
 
  Subject to the limitations of the 1996 Plan, the Committee may grant
restricted shares to Eligible Individuals. Restricted shares are Shares of
Company Common Stock that are subject to restrictions on transfer or other
incidents of ownership where the restrictions lapse based solely on continued
employment with the Company for specified periods or based on the attainment
of specified performance standards, in either case, as the Committee may
determine. The Committee shall determine all terms and conditions pursuant to
which restrictions upon restricted shares shall lapse. At the discretion of
the Committee, Shares of Company Common Stock issued in connection with the
grant of restricted shares shall be deposited in escrow until the restriction
period ends. Upon delivery to the escrow account, the grantee shall have all
the rights of a stockholder with respect to the restricted shares and may
receive dividends, unless the Committee determines otherwise. Dividends may,
at the discretion of the Committee, be deferred until the restriction period
ends and may be reinvested in Shares of Company Common Stock.
 
  With respect to an award of performance-based restricted shares, the
Committee shall specify a period of time (a "Performance Cycle") over which
certain "Performance Objectives" must be met. Performance Objectives for
restricted shares are goals established by the Committee that are intended to
meet the requirements under Section 162(m) of the Code to be considered pre-
established performance goals. Performance objectives may be expressed in
terms of earnings per share, share price, pre-tax profits, net earnings,
return on equity or assets, revenues or any combination of the foregoing and
may be particular to an employee or the division, department, market, line of
business, subsidiary or other unit in which the grantee works, or may be based
on the performance of the Company generally.
 
  The Committee shall determine the Eligible Individuals to whom restricted
shares shall be awarded, whether the restricted shares should be performance
based, the duration of the applicable Performance Cycle, the number of
restricted shares to be delivered at the end of a Performance Cycle, whether
the Performance Objectives are met or exceeded and other terms and conditions
of each Employee Award.
 
  The grantee shall become vested with respect to performance based restricted
shares to the extent that Performance Objectives are satisfied for the
Performance Cycle, as indicated by the Committee's written certification. If
the Performance Objectives are not met, all restricted shares shall be
forfeited for that Performance Cycle.
 
  If a grantee's employment terminates by reason of death or disability or, in
the case of restricted shares that are not performance based, retirement,
prior to the expiration of the restriction period applicable to any restricted
shares then held by the grantee, all restrictions pertaining to such Shares of
Company Common Stock immediately lapse. Upon termination for any other reason,
all restricted shares are forfeited, provided, however, that except with
respect to performance based restricted shares, the Committee may (i) provide
that the
 
                                      25
<PAGE>
 
restrictions on some or all of the Shares of Company Common Stock held by a
grantee shall lapse upon the grantee's termination of employment and (ii)
accelerate or waive any or all restrictions and conditions applicable to any
award of restricted shares.
 
CHANGE IN CONTROL
 
  Generally, in the event of a Change in Control of the Company, all
outstanding stock options become fully vested and immediately exercisable in
their entirety and generally to the extent set forth in an optionee's
agreement, the optionee will be permitted, during the 60-day period following
the Change in Control, to surrender for cancellation any stock option (or
portion thereof) for a cash payment in respect of each share of Common Stock
covered by the stock option or portion thereof surrendered, equal to the
excess, if any, of (x) (A) in the case of a nonqualified stock option, the
greater of (1) the fair market value of a Share of Company Common Stock on the
date preceding the date of surrender or (2) the Adjusted Fair Market Value of
a Share of Company Common Stock or (B) in the case of an incentive stock
option, the fair market value of a Share of Company Common Stock on the date
preceding the date of surrender, over (y) the per share exercise price for
such Shares of Company Common Stock under the stock option. In addition, all
restrictions on restricted shares lapse upon a Change in Control.
 
AMENDMENTS AND TERMINATION
 
  The Board of Directors may at any time terminate and, from time to time, may
amend or modify the 1996 Plan, provided, however, that no amendment may impair
the rights of a participant with respect to outstanding Employee Awards
without the participant's consent. Any such action of the Board of Directors
may be taken without the approval of the Company's stockholders, but only to
the extent that such stockholder approval is not required by applicable law or
regulation. The 1996 Plan will terminate ten years from its effective date.
 
FEDERAL INCOME TAX CONSIDERATIONS
 
  The following discussion summarizes the federal income tax consequences to
participants who may receive Employee Awards under the 1996 Plan. The
discussion is based upon interpretations of the Code in effect as of January
1, 1998, and regulations promulgated thereunder as of such date.
 
  Nonqualified Stock Options. For federal income tax purposes, no income is
recognized by a participant upon the grant of a Nonqualified Stock Option
under the 1996 Plan. Upon the exercise of an option, however, compensation
taxable as ordinary income will be realized by the participant in an amount
equal to the excess of the fair market value of a share of the Common Stock on
the date of such exercise over the exercise price. A subsequent sale or
exchange of such Shares of Company Common Stock will result in gain or loss
measured by the difference between (i) the exercise price, increased by any
compensation reported upon the participant's exercise of the option, and (ii)
the amount realized on such sale or exchange. Such gain or loss will be
capital in nature if the Shares of Company Common Stock were held as a capital
asset and will be long-term if such Shares of Company Common Stock were held
for more than 18 months. Special rules may apply to an optionee who is subject
to Section 16(b) of the Exchange Act.
 
  The Company is entitled to a deduction (subject to the provisions of Section
162(m) of the Code and to compliance with the applicable income reporting
requirements) for compensation paid to a participant at the same time and in
the same amount as the participant is considered to have realized compensation
by reason of the exercise of an option.
 
  Incentive Stock Options. No taxable income is realized by a participant upon
the grant or exercise of an incentive stock option. If Shares of the Company
Common Stock are issued to a participant pursuant to the exercise of an
incentive stock option granted under the 1996 Plan, and if no disqualifying
disposition of such Shares of Company Common Stock is made by such participant
within two years after the date of grant or within one year after the transfer
of such Shares of Company Common Stock to the participant, then (a) upon sale
of such Shares of Company Common Stock, any amount realized in excess of the
exercise price will be taxed to
 
                                      26
<PAGE>
 
such participant as a long-term capital gain, if the 18-month holding period
is met and any loss sustained will be a long-term capital loss, if the 18-
month holding period is met, and (b) no deduction will be allowed to the
Company for federal income tax purposes. Upon exercise of an incentive stock
option, the excess of the fair market value on the date of exercise over the
exercise price may be included as an item of tax preference for alternative
minimum tax purposes.
 
  If Shares of the Company Common Stock acquired upon the exercise of an
incentive stock option are disposed of prior to the expiration of the two-
years-from-grant/one-year-from-transfer holding period, generally (a) the
participant will realize ordinary income in the year of disposition in the
amount equal to the excess (if any) of the fair market value of the Shares of
Company Common Stock at exercise (or, if less, the amount realized on the
disposition of the Shares of Company Common Stock) over the exercise price
thereof, and (b) the Company will be entitled to deduct such amount (subject
to the provisions of Section 162(m) of the Code and compliance with the
applicable income reporting requirements). Any further gain or loss realized
will be taxed as capital gain or loss, as the case may be, and will not result
in any deduction by the Company.
 
  If an incentive stock option is exercised at a time when it no longer
qualifies as an incentive stock option, the option is treated as a
nonqualified stock option for tax purposes.
 
  Restricted Shares. Awards of restricted shares will not result in taxable
income to the employee or a tax deduction to the Company for federal income
tax purposes at the time of grant. A recipient of restricted shares generally
will be subject to tax at ordinary income tax rates based on the fair market
value of the Common Stock at the time the restricted shares are no longer
subject to risk of forfeiture. However, a recipient who so elects under
Section 83(b) of the Code within 30 days of the date of the grant will have
ordinary taxable income on the date of the grant equal to the fair market
value of the restricted shares as if such Shares of Company Common Stock were
unrestricted and could be sold immediately. If the restricted shares subject
to such election are forfeited, the recipient will not be entitled to any
deduction, refund or loss for tax purposes with respect to the forfeited
Shares of Company Common Stock. Upon sale of the restricted shares after the
risk of forfeiture lapses, the holding period to determine whether the
recipient has long-term or short-term capital gain or loss begins when the
restriction period expires. However, if the recipient timely elects to be
taxed as of the date of the grant, the holding period commences on the date of
the grant and the tax basis will be equal to the fair market value of the
restricted shares on the date of the grant as if such Shares of Company Common
Stock were then unrestricted and could be sold immediately. Special rules may
apply to a recipient of restricted shares who is subject to Section 16(b) of
the Exchange Act.
 
  The Company is entitled to a deduction (subject to the provisions of Section
162(m) of the Code and compliance with the applicable income reporting
requirements) for compensation paid to a participant at the same time and in
the same amount as the participant is considered to have realized compensation
by reason of the lapse of restrictions on an award of restricted shares.
 
  Limits on Deductions. Under Section 162(m) of the Code, the amount of
compensation paid to the Chief Executive Officer and the four other most
highly paid executive officers of the Company in the year for which a
deduction is claimed by the Company (including its subsidiaries) is limited to
$1,000,000 per person, except that compensation that is performance-based will
be excluded for purposes of calculating the amount of compensation subject to
this $1,000,000 limitation.
 
  The Company has structured the 1996 Plan so that any compensation for which
the Company may claim a deduction in connection with the exercise of
nonqualified stock options, the disposition by an optionee of Shares of
Company Common Stock acquired upon the exercise of incentive stock options and
the lapse of restrictions on Performance Based Restricted stock will all be
"performance-based compensation" within the meaning of Section 162(m) of the
Code. The only Employee Awards under the 1996 Plan which are not performance-
based are restricted shares not subject to performance restrictions, and
therefore, any amounts for which the Company may claim a deduction in
connection therewith will be subject to the limitations on deductibility in
Section 162(m) of the Code.

NEW PLAN BENEFITS
 
  As described above, the selection of the Eligible Individuals who will
receive Employee Awards under the 1996 Plan, upon approval of the Plan by
stockholders, and the size and type of awards is to be determined by the
Committee in its discretion.
 
  The following table shows awards under the 1996 Plan for the fiscal year
ended December 31, 1997. During 1997, an award of restricted stock was made to
each of Gregory H. Wolf and Jerry D. Reeves, M.D. and in 1996 an award was
made to Mr. Wolf as set out in the Summary Compensation Table herein. Except
as indicated, no other awards of restricted stock have been made under the
1996 Plan. These grants are not necessarily indicative of awards that may be
made in the future.

  Approval of the 1996 Plan requires the affirmative vote of the holders of a
majority of the Shares of Company Common Stock represented at the Annual
Meeting, in person or by proxy, and entitled to vote.
 
  THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR
APPROVAL OF THE AMENDMENT OF THE 1996 PLAN TO INCREASE THE SHARES OF COMPANY

                               OTHER INFORMATION
 
VOTING RIGHTS AND PROXY INFORMATION
 
  Stockholders of Record of the Company's outstanding Shares of Company Common
Stock as of the close of business on March 17, 1998, (the "Annual Meeting
Record Date") are entitled to vote at the Annual Meeting or any adjournment or
postponement thereof. Stockholders of Record are entitled to one vote per
share on any matter which may properly come before the Annual Meeting.
 
  The presence at the Annual Meeting, in person or by proxy, of Stockholders
of Record of a majority of the Shares of Company Common Stock issued and
outstanding on the Annual Meeting Record Date, and entitled to vote, shall be
necessary and sufficient to constitute a quorum for the transaction of
business. Any Stockholder of Record present (including broker non-votes) at
the Annual Meeting, but who abstains from voting, shall be counted for
purposes of determining whether a quorum is present at the Annual Meeting. As
of the Annual Meeting Record Date, there were 165,874,429 Shares of Company
Common Stock outstanding and entitled to vote at the Annual Meeting.
 
  The affirmative vote of a plurality of the Shares of Company Common Stock
represented in person or by properly executed proxy is required to approve the
election of each of the Company's nominees for election as a director.
 
  The affirmative vote of a majority of the Shares of Company Common Stock
represented at the Annual Meeting, in person or by proxy, and entitled to vote
at the Annual Meeting, will be necessary to approve the amendments to the
Directors Stock Plan, the 1998 MIP, and the amendment to the 1996 Stock Plan.
 
  Since only a plurality is required for the election of directors,
abstentions or broker non-votes will have no effect on the election of
directors (except for purposes of determining whether a quorum is present at
the Annual Meeting). With respect to the approval of the amendments to the
Directors Stock Plan, the 1998 MIP, and the amendment to the 1996 Stock Plan,
an abstention (or broker non-vote) has the same effect as a vote against the
proposal.
 
  All Shares of Company Common Stock that are represented at the Annual
Meeting by properly executed proxies received prior to or at the Annual
Meeting and not revoked will be voted at the Annual Meeting in accordance with
the instructions indicated in such proxies. If no instructions are indicated,
such executed proxies will be voted FOR approval of the election of the Board
of Directors' eight nominees as directors of the Company, FOR approval of the

under the Plan after January 31, 1998 shall not exceed 165,000. Such number of
Shares is subject to adjustment as provided in Section 14. In the event that

five thousand (5,000) Shares of Company Stock will automatically be made to
each non-employee director of the Company who has been a director continuously
for a least the full calendar year prior thereto.
 
  Each such automatic grant will be for Non-Qualified Options at the Fair
Market Value of the Stock on date of grant and will vest and become

<PAGE>
 
  10.EXERCISE OF OPTION. The Committee shall have full authority in its
discretion to determine when Options may be exercised, including the ability
to accelerate exercise dates of Options previously granted under the Plan. The
purchase price of the Shares as to which an Option shall be exercised shall be
paid in full at the time of exercise at the election of the holder of an
Option (a) in cash or currency of the United States of America, (b) by
tendering to the Company Shares then owned having a Fair Market Value equal to
the cash exercise price applicable to the purchase price of the Shares as to
which an Option is being exercised, or (c) partly in cash and partly in Shares
valued at Fair Market Value. Such Fair Market Value for the tendered Shares
shall be determined as of the close of the business day immediately preceding
the day on which the Option is exercised. Fractional Shares will not be
issued. The right to purchase Shares shall be cumulative so that when the
right to purchase any Shares has accrued such Shares or any part thereof may
be purchased at any time thereunder until the expiration or termination of the
Option.
 
  11.TAX WITHHOLDING. With respect to any Option or Award the Committee may,
in its discretion and subject to such rules as the Committee may adopt, permit
a participant to satisfy, in whole or in part, any withholding tax obligation
which may arise in connection with the exercise of such option or the receipt
of an Award by electing to (a) have the Company withhold or collect cash; or
(b) deliver to the Company on the date on which the amount of tax to be
withheld is determined (the "Tax Date") the Shares acquired at exercise or
upon the Award, or owned prior to such Option exercise or Award having a Fair
Market Value equal to the amount of the withholding tax; or (c) a combination
of (a) and (b).
 
  12.RESIGNATION, RETIREMENT, DEATH OR DISABILITY. If an Optionee is removed
from the Board for cause, all of the Option rights of such Optionee, whether
or not exercisable, under any then outstanding Option shall terminate
immediately. If Optionee resigns for any reason other than for cause,
Retirement, death or Disability, an Option shall be exercisable by such
Optionee or personal representative at any time prior to the expiration date
of the Option or within ninety (90) days after the date of such termination,
whichever is the shorter period, but only to the extent of the accrued right
to exercise at the date of such termination. In the event of Retirement, an
Option shall be exercisable by such Optionee at any time prior to the
expiration date of the Option or within two (2) years after the date of such
Retirement, whichever is the shorter period, but only to the extent of the
accrued right to exercise at the date of Retirement. In the event of death or
Disability of an Optionee while serving on the Board of the Company, all
Options of such Optionee then outstanding shall become immediately
exercisable. In the event of death of an Optionee, all Options of such
Optionee shall be exercisable by the person or the persons to whom those
rights pass by will or by the laws of descent and distribution or, if
appropriate, by the legal representative of the estate of the deceased
Optionee at any time within two (2) years after the date of such death,
regardless of the expiration date of the Options. In the event of Disability
of an Optionee all Options of such Optionee shall be exercisable by the
Optionee or if incapacitated, by a legal representative at any time within two
(2) years of the date of determination of Disability regardless of the
expiration date of the Options.
 
  13.RESTRICTIONS ON TRANSFER. No Option granted under the Plan shall be
transferable by an Optionee other than by will or, if the Optionee dies
intestate, by the laws of descent and distribution of the state of such
Optionee's domicile at the time of death. An Option shall be exercisable
during the lifetime of an Optionee only by such Optionee or, if incapacitated
because of Disability, by a legal representative.
 
  14.CAPITAL ADJUSTMENTS AFFECTING STOCK. In the event of a capital adjustment
resulting from a stock dividend, stock split, reverse stock split,
reorganization, merger, consolidation, combination or exchange of stock,
spinoff or other change in corporate structure or capitalization affecting the
stock, the number of Shares or other Stock or securities subject to the Plan,
then the number of Shares or other Stock or securities subject to Options
shall be adjusted in a manner consistent with such capital adjustment. The
purchase price of the Shares or other securities subject to the Options shall
be adjusted so that there will be no material change in the aggregate purchase
price payable upon exercise of any such Options or other options or rights
granted; provided, however, that such adjustments shall be made in a manner
which preserves, without exceeding, the then existing value of the Option.

  15.CORPORATE MERGERS, ACQUISITIONS, ETC. The Committee may grant Options or,
with the consent of the Option holder, modify Options under the Plan to
include such provisions as it deems necessary and in the best interest of the
Company and the Optionee to preserve for the Optionee the benefits of any
appreciation of the underlying Stock during the term of the Option which
benefits might otherwise be lost as a result of (a) the acquisition by any
single entity or group of affiliated entities of at least fifty percent (50%)
of the outstanding Company stock, or (b) a reorganization, merger or
consolidation of the Company as a result of which the Company is not the
surviving corporation, or (c) a sale of all or substantially all of the assets
of the Company to another entity. The Committee may also grant Options having
terms and provisions which vary from those specified in the Plan provided that
any Options granted pursuant to this Section 15 are granted in substitution
for or in connection with the assumption of existing Options granted by
another corporation and assumed or otherwise agreed to be provided for by the
Company pursuant to or by reason of a transaction involving a corporate
merger, consolidation, acquisition of property or stock, separation,
reorganization or liquidation to which the Company is a party.
 
  16.LIMITED RIGHTS. The Committee may grant a limited right (a "Limited
Right") to the holder of any Option granted under the Plan (the "Related
Option") with respect to all or some of the Shares covered by such Related
Option. A Limited Right may be exercised during a period determined by the
Committee beginning on the first (1st) day following (a) the acquisition by
any single entity or group of affiliated entitles (other than the Company or
any of its subsidiaries) of at least fifty percent (50%) of the outstanding
Company Stock, or (b) receipt of stockholder approval of a definitive
agreement providing for the reorganization, merger or consolidation of the
Company in which the Company is not the surviving corporation, or providing
for a sale of all or substantially all of the assets of the Company to another
entity, and ending as determined by the Committee. Upon exercise of a Limited
Right, the Related Option shall cease to be exercisable to the extent of the
Shares with respect to which such Limited Right is exercised but shall be
considered to have been exercised to that extent for purposes of determining
the number of Shares available for the grant of further Options pursuant to
the Plan.
 
  The term "Spread" as used in this Section shall mean, with respect to the
exercise of any Limited Right, an amount equal to the product of (a) the
excess of the Fair Market Value per Share of the Company's Stock on the date
of exercise over the per Share exercise price under the Related Option times
(b) the number of Shares with respect to which such Limited Right is being
exercised.
 
  Upon exercise of a Limited Right, the holder thereof shall receive an amount
equal to the value of such Spread.
 
  The Committee may impose such additional conditions or limitations on
Limited Rights as it deems necessary or desirable to secure for the holders
thereof the benefits of Section 16 of the Exchange Act or any successor
provision in effect at the time of grant or exercise of such rights, or as it
may otherwise deem advisable.
 
  No Limited Right shall be transferable except by will or by the laws of
descent and distribution. During the life of a holder of a Limited Right, the
Limited Right shall be exercisable only by that person.
 
  17.AMENDMENT TO THE PLAN. The Board shall have the right to amend, suspend
or terminate the Plan at any time without the approval of stockholders of the
Company, to the extent such approval is not required pursuant to the Exchange
Act.
 
  18.EFFECTIVE DATE AND TERM OF THE PLAN. The effective date of the Plan, as
amended, is May 14, 1998. No Options or Awards may be granted under the Plan
after May 14, 2008.
 
  19.EXCHANGE ACT SECTION 16. Transactions under this Plan are intended to
comply with all applicable conditions of Rule 16b-3 or its successor under the
Exchange Act. To the extent any provision of the Plan or action by the Plan
administrators fails to so comply, it shall be deemed null and void, to the
extent permitted by law and deemed advisable by the Committee.

  I. OBJECTIVES. The objective of the Humana Inc. 1998 Executive Management
Incentive Compensation Plan (the "Plan") is to reward executive officers for

  B.Incentive compensation will be computed by measuring (i) the Company's
achievement of actual consolidated net income ("Consolidated Net Income")
measured as Earnings Per Share ("EPS") for each fiscal year against
Consolidated Net Income/EPS objectives established by the Committee for each
fiscal year, and/or (ii) Growth Objectives or Profit Objectives, the relative

time and approved by the Company's shareholders in accordance with Internal
Revenue Service regulations promulgated under Section 162(m) of the Internal
Revenue Code.
 
  C.Incentive compensation for a fiscal year shall be based on the
Participant's salary at the beginning of such fiscal year exclusive of any
bonus or fringe benefits paid or accrued during such fiscal year ("Salary").
The maximum incentive compensation paid for any fiscal year to any Participant
shall not exceed one hundred and twenty five percent (125%) of Salary; the
precise percentage earned shall be based upon a schedule of target goals
established pursuant to Section II B. above. The Committee may not increase
this maximum but may, in its sole discretion, decrease the amount of incentive
compensation to be paid for any fiscal year to an amount less than would be
payable based on the Company's actual performance for that year.
Notwithstanding anything herein to the contrary, the maximum incentive
compensation paid for any fiscal year to any Participant may not exceed Two
Million Dollars ($2,000,000).
 
  D.The Company's achievement of predetermined goals for each fiscal year will
be determined in accordance with generally accepted accounting principles;
provided, however, that (i) the effects of accounting policy changes from the
prior fiscal year and unusual non-recurring gains and losses will be excluded,
and (ii) incentive compensation generated pursuant to incentive plans of the
Company, including this Plan, shall be accrued and deducted as an expense for
such fiscal year.
 
  E.Incentive compensation will be paid to Participants on or before March 15
following the close of the fiscal year in respect of which it was earned.
 
  III. ADMINISTRATION OF THIS PLAN. This Plan shall be administered by the
Committee, which shall have full power and final authority to construe,
interpret and administer the Plan. Following the close of a fiscal year and
before any payments are made hereunder for that fiscal year, the Committee
must certify in writing whether and to what extent the performance goals have
been satisfied. No member of the Committee shall be personally liable for
damage, in the absence of bad faith, for any act or omission with respect to
service on the Committee.
 
  IV. ELIGIBILITY DURING FISCAL YEAR. Subject to the discretion of the
Committee as set forth in Section II C. of this Plan, an individual who
becomes a Participant in this Plan due to employment, transfer or promotion
during the fiscal year will be eligible to receive partial incentive
compensation based upon the
 
                                      B-1

event, however, will partial payments be made for any period of time of less
than two (2) months.
 
  V. INELIGIBILITY DURING FISCAL YEAR. A Participant in this Plan who becomes
ineligible during the fiscal year due to transfer or change of position shall
cease to be eligible for further participation in this Plan on the date of
transfer or change to the ineligible position. Subject to the discretion of the
Committee as set forth in Section II C. of this Plan, if the Participant, prior
to the date of transfer or change, has been a Participant in the Plan for a
minimum of two (2) calendar months of the fiscal year, the Participant will be
eligible to receive partial incentive compensation based upon the Participant's
Salary for such period of time and the level of achievement in relation to
targeted goals for the entire fiscal year.
 
  VI. TERMINATION OF EMPLOYMENT; LEAVE OF ABSENCE. Subject to the discretion of
the Committee as set forth in Section II C. of this Plan, a Participant who has
been employed (i) during the entire fiscal year for which incentive
compensation is to be paid, but whose employment is terminated, voluntarily or
involuntarily (other than for cause), or who is granted a leave of absence
after the end of such fiscal year and prior to the payment date therefor will
be eligible to receive his/her full incentive compensation with respect to such
fiscal year as determined in accordance with the provisions of this Plan, or
(ii) through the first two (2) calendar months of any fiscal year, but whose
employment is terminated, voluntarily or involuntarily (other than for cause),
or who is granted a leave of absence after the end of the first two (2)
calendar months of any fiscal year but prior to the end of such fiscal year
will be eligible to receive partial incentive compensation with respect to such
fiscal year based upon the Participant's Salary for the period of time he/she
was a Participant at the level of achievement in relation to targeted goals for
the entire fiscal year. A Participant whose employment is terminated for cause
or whose employment is terminated for any other reason prior to the end of the
first two (2) calendar months of such fiscal year shall not be eligible to
receive any incentive compensation under this Plan other than those amounts
which have been paid to him/her prior to the date he/she is terminated.
 
  VII. DEFERRED COMPENSATION. A Participant in this Plan may irrevocably elect
to defer receipt of any amount earned pursuant to this Plan, provided such
election is made in writing. The terms of any deferred compensation arrangement
must be approved in writing by the Chairman of the Committee and the
Participant. Any amount deferred pursuant to this Plan will bear interest at a
rate determined by the Committee.
 
  VIII. COMPANY'S RIGHT TO TERMINATE. The Company shall have the right to
terminate this Plan, with or without notice, in whole or in part, at any time.
 
  IX. GENERAL PROVISIONS.
 
  A. No person has any claim or right to be included in this Plan or to be
granted incentive compensation under this Plan until such individual has been
declared a Participant and received an official written notice thereof in
accordance with the procedures as set forth in this Plan. In addition, all of
the requirements and applicable rules and regulations of this Plan must have
been met including, but not limited to the availability of funds for incentive
compensation awards and the determination by the Committee of the extent to
which targeted goals have been met.
 
  B. The designation of an individual as a Participant under this Plan does not
in any way alter the nature of the Participant's employment relationship.
 
  X. SHAREHOLDER APPROVAL. Notwithstanding anything herein to the contrary,
this Plan is subject to and conditioned upon the approval of the Company's
shareholders at the May 14, 1998 annual meeting of shareholders.

be deemed null and void, to the extent permitted by law and deemed advisable by
the Committee.

      (a) An acquisition (other than directly from the Company) of any
    voting securities of the Company (the "Voting Securities") by any
    "Person" (as the term person is used for purposes of Section 13(d) or
    14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
    Act")), immediately after which such Person has "Beneficial Ownership"
    (within the meaning of Rule 13d-3 promulgated under the Exchange Act)
    of twenty percent (20%) or more of the combined voting power of the
    Company's then outstanding Voting Securities; provided, however, in
    determining whether a Change in Control has occurred, Voting Securities
    which are acquired in a "Non-Control Acquisition" (as hereinafter
    defined) shall not constitute an acquisition which would cause a Change
    in Control. A "Non-Control Acquisition" shall mean an acquisition by
    (i) an employee benefit plan (or a trust
 
                                      C-1
<PAGE>
 
    forming a part thereof) maintained by (A) the Company or (B) any
    corporation or other Person of which a majority of its voting power or
    its equity securities or equity interest is owned, directly or
    indirectly, by the Company (for purposes of this definition, a
    "Subsidiary") (ii) the Company or its Subsidiaries, or (iii) any Person
    in connection with a "Non-Control Transaction" (as hereinafter
    defined);
 
      (b) The individuals who, as of the effective date of this Plan are
    members of the Board (the "Incumbent Board"), cease for any reason to
    constitute at least two-thirds of the members of the Board; provided,
    however, that if the election, or nomination for election by the
    Company's common stockholders, of any new director was approved by a
    vote of at least two-thirds of the Incumbent Board, such new director
    shall, for purposes of this Plan, be considered as a member of the
    Incumbent Board; provided further, however, that no individual shall be
    considered a member of the Incumbent Board if such individual initially
    assumed office as a result of either an actual or threatened "Election
    Contest" (as described in Rule 14a-11 promulgated under the Exchange
    Act) or other actual or threatened solicitation of proxies or consents
    by or on behalf of a Person other than the Board (a "Proxy Contest")
    including by reason of any agreement intended to avoid or settle any
    Election Contest or Proxy Contest; or
 
      (c) The consummation of:
 
        (i) A merger, consolidation or reorganization involving the
      Company, unless such merger, consolidation or reorganization is a
      "Non-Control Transaction." A "Non-Control Transaction" shall mean a
      merger, consolidation or reorganization of the Company where:
 
                (A) the stockholders of the Company, immediately before such
              merger, consolidation or reorganization, own directly or
              indirectly immediately following such merger, consolidation or
              reorganization, at least seventy-five percent (75%) of the
              combined voting power of the outstanding Voting Securities of
              the corporation resulting from such merger or consolidation or
              reorganization (the "Surviving Corporation") in substantially
              the same proportion as their ownership of the Voting Securities
              immediately before such merger, consolidation or reorganization,
 
                (B) the individuals who were members of the Incumbent Board
              immediately prior to the execution of the agreement providing
              for such merger, consolidation or reorganization constitute at
              least two-thirds of the members of the board of directors of the
              Surviving Corporation, or a corporation beneficially directly or
              indirectly owning a majority of the Voting Securities of the
              Surviving Corporation, and no agreement, plan or arrangement is
              in place to change the composition of the board of directors
              following the merger, consolidation or reorganization; and
 
                (C) no Person other than (i) the Company, (ii) any Subsidiary,
              (iii) any employee benefit plan (or any trust forming a part
              thereof) maintained by the Company, the Surviving Corporation,
              or any Subsidiary, or (iv) any Person who, immediately prior to
              such merger, consolidation or reorganization had Beneficial
              Ownership of twenty percent (20%) or more of the then
              outstanding Voting Securities, has Beneficial Ownership of
              twenty percent (20%) or more of the combined voting power of the
              Surviving Corporation's then outstanding voting securities.
 
        (ii) A complete liquidation or dissolution of the Company; or
 
        (iii) The sale or other disposition of all or substantially all of
      the assets of the Company to any Person (other than a transfer to a
      Subsidiary).
 
  Notwithstanding the foregoing, a Change in Control shall not be deemed to
occur solely because any Person (the "Subject Person") acquired Beneficial
Ownership of more than the permitted amount of the then outstanding Voting
Securities as a result of the acquisition of Voting Securities by the Company
which, by
 
                                      C-2
<PAGE>
 
reducing the number of Voting Securities then outstanding, increases the
proportional number of Shares Beneficially Owned by the Subject Persons,
provided that if a Change in Control would occur (but for the operation of this
sentence) as a result of the acquisition of Voting Securities by the Company,
and after such share acquisition by the Company, the Subject Person becomes the
Beneficial Owner of any additional Voting Securities which increases the
percentage of the then outstanding Voting Securities Beneficially Owned by the
Subject Person, then a Change in Control shall occur.

10,650,000; provided, however, that in the aggregate, not more than fifteen
percent (15%) of the Shares authorized under the Plan may be made the subject
of Restricted Stock Awards under Section 6 of the Plan and, provided, further,
that during the term of the Plan, no Eligible Individual may be granted
Options and Awards in the aggregate in respect of more than fifteen percent
(15%) of the Shares authorized under the Plan. Upon a Change in
Capitalization, the maximum number of Shares referred to in the preceding
sentence shall be adjusted in number and kind pursuant to Section 7. The
Company shall reserve for the purposes of the Plan, out of its authorized but
unissued Shares or out of Shares held in the Company's treasury, or partly out
of each, such number of Shares as shall be determined by the Board.
 
  4.2 Upon the granting of an Option or an Award, the number of Shares
available under Section 4.1 for the granting of further Options and Awards
will be reduced by any such Options or Awards granted.
 
  4.3 Whenever any outstanding Option or Award or portion thereof expires, is
canceled or is otherwise terminated or forfeited for any reason without having
been exercised or payment having been made in respect of the entire Option or
Award, the Shares allocable to the expired, canceled or otherwise terminated
portion of the Option or Award may again be the subject of Options or Awards
granted hereunder.
 
  5. OPTION GRANTS FOR ELIGIBLE INDIVIDUALS.
 
  5.1 Authority of Committee. Subject to the provisions of the Plan, the
Committee shall have full and final authority to select those Eligible
Individuals who will receive Options, and the terms and conditions thereof.
The grant of an Option and the terms and conditions thereof shall be set forth
in an Agreement.
 
  5.2 Purchase Price. The purchase price or the manner in which the purchase
price is to be determined for Shares under each Option shall be determined by
the Committee and set forth in the Agreement; provided, however, that the
purchase price per Share under each Option shall not be less than 100% of the
Fair Market Value of a Share on the date the Option is granted (110% in the
case of an Incentive Stock Option granted to a Ten-Percent Stockholder).
 
 
                                      C-5
<PAGE>
 
  5.3 Maximum Duration. Options granted hereunder shall be for such term as
the Committee shall determine, provided that an Incentive Stock Option shall
not be exercisable after the expiration of ten (10) years from the date it is
granted (five (5) years in the case of an Incentive Stock Option granted to a
Ten-Percent Stockholder) and except as set out in Section 5.5(d), a
Nonqualified Stock Option shall not be exercisable after the expiration of ten
(10) years from the date it is granted. The Committee may, subsequent to the
granting of any Option, extend the term thereof but in no event shall the term
as so extended exceed the maximum term provided for in the preceding sentence.
 
  5.4 Vesting. Subject to Section 5.10, each Option shall become exercisable
in such installments (which need not be equal) and at such times as may be
designated by the Committee and set forth in the Agreement. To the extent not
exercised, installments shall accumulate and be exercisable, in whole or in
part, at any time after becoming exercisable, but not later than the date the
Option expires. The Committee may accelerate the exercisability of any Option
or portion thereof at any time.
 
  5.5 Termination of Employment, Death or Disability.
 
  Unless otherwise determined by the Committee:
 
    (a) If the employment of an Eligible Individual by the Company is
  terminated for Cause, all the rights of such Eligible Individual, whether
  or not exercisable, under any then outstanding Option shall terminate
  immediately.
 
    (b) If the employment of the Eligible Individual is terminated for any
  reason other than for Cause, Retirement, death or Disability, an Option
  shall be exercisable by such Eligible Individual or a personal
  representative at any time prior to the expiration date of the Option or
  within ninety (90) days after the date of such termination, whichever is
  the shorter period, but only to the extent the Option was exercisable at
  the date of termination.
 
    (c) In the event of Retirement, an Option shall be exercisable by such
  Eligible Individual at any time prior to the expiration date of the Option
  or within two (2) years after the date of such Retirement, whichever is the
  shorter period, but only to the extent the Option was exercisable at the
  date of such Retirement.
 
    (d) In the event of death or Disability of an Eligible Individual while
  in the employ of the Company, all Options of such Eligible Individual then
  outstanding shall become immediately exercisable in full. In the event of
  death of an Eligible Individual, all Options of such Eligible Individual
  shall be exercisable by the person or the persons to whom those rights pass
  by will or by the laws of descent and distribution or, if appropriate, by
  the legal representative of the estate of the deceased Eligible Individual
  at any time within two (2) years after the date of death, regardless of the
  expiration date of the Option, except for Incentive Stock Options which may
  not be exercised later than the expiration date of the Options. In the
  event of Disability of an Eligible Individual all Options of such Eligible
  Individual shall be exercisable by the Eligible Individual or, if
  incapacitated, by a legal representative at any time within two (2) years
  of the date of determination of Disability regardless of the expiration
  date of the Options, except for Incentive Stock Options which may not be
  exercised later than the expiration date of the Options.
 
  5.6 Modification. Subject to the terms of the Plan, the Committee may modify
outstanding Options or accept the surrender of outstanding Options (to the
extent not yet exercised) and grant new Options in substitution for them. No
modification of an Option shall adversely alter or impair any rights or
obligations under the Option without the Optionee's consent.
 
  5.7 Non-Transferability. No Option granted hereunder shall be transferable
by the Optionee to whom granted except by will or the laws of descent and
distribution, and an Option may be exercised during the lifetime of such
Optionee only by the Optionee or his or her guardian or legal representative.
The terms of such Option shall be final, binding and conclusive upon the
beneficiaries, executors, administrators, heirs and successors of the
Optionee.
 
                                      C-6
<PAGE>
 
  5.8 Method of Exercise. The exercise of an Option shall be made only by a
written notice delivered in person or by mail to the Secretary of the Company
at the Company's principal executive office, specifying the number of Shares
to be purchased and accompanied by payment therefor and otherwise in
accordance with the Agreement pursuant to which the Option was granted. The
purchase price for any Shares purchased pursuant to the exercise of an Option
shall be paid, as determined by the Committee in its discretion, in either of
the following forms (or any combination thereof): (i) cash or (ii) the
transfer of Shares previously owned by Optionee, for a time period determined
by the Committee, to the Company upon such terms and conditions as determined
by the Committee. Any Shares transferred to the Company as payment of the
purchase price under an Option shall be valued at their Fair Market Value on
the day preceding the date of exercise of such Option. In addition, Options
may be exercised through a registered broker-dealer pursuant to such cashless
exercise procedures (other than Share withholding) which are, from time to
time, deemed acceptable by the Committee. No fractional Shares (or cash in
lieu thereof) shall be issued upon exercise of an Option and the number of
Shares that may be purchased upon exercise shall be rounded to the nearest
number of whole Shares.
 
  5.9 Rights of Optionees. No Optionee shall be deemed for any purpose to be
the owner of any Shares subject to any Option unless and until (i) the Option
shall have been exercised pursuant to the terms thereof, (ii) the Company
shall have issued and delivered Shares to the Optionee and (iii) the
Optionee's name shall have been entered as a stockholder of record on the
books of the Company. Thereupon, the Optionee shall have full voting,
dividend, and other ownership rights with respect to such Shares, subject to
such terms and conditions as may be set forth in the applicable Agreement.
 
  5.10 Effect of Change in Control. Except as may be set forth in an
Agreement, in the event of a Change in Control, all Options outstanding on the
date of such Change in Control shall become immediately and fully exercisable.
In the event an Optionee's employment with the Company is terminated other
than for Cause within three (3) years following a Change in Control, each
Option held by the Optionee that was exercisable as of the date of termination
of the Optionee's employment or service shall remain exercisable for a period
ending the earlier of the second anniversary of the termination of the
Optionee's employment or service or the expiration of the stated term of the
Option.
 
  In addition, to the extent set forth in an Agreement evidencing the grant of
an Option, an Optionee will be permitted to surrender for cancellation within
sixty (60) days after such Change in Control any Option or portion of an
Option to the extent not yet exercised and the Optionee will be entitled to
receive a payment in an amount equal to the excess, if any, of (x) (A) in the
case of a Nonqualified Stock Option, the greater of (1) the Fair Market Value,
on the date preceding the date of surrender, of the Shares subject to the
Option or portion thereof surrendered or (2) the Adjusted Fair Market Value of
the Shares subject to the Option or portion thereof surrendered or (B) in the
case of an Incentive Stock Option, the Fair Market Value, on the date
preceding the date of surrender, of the Shares subject to the Option or
portion thereof surrendered, over (y) the aggregate purchase price for such
Shares under the Option or portion thereof surrendered. The form of payment
shall be determined by the Committee.
 
  6. RESTRICTED STOCK.
 
  6.1 Grant. The Committee shall have full and final authority to select those
Eligible Individuals who will receive an Award of Restricted Stock, which
shall be evidenced by an Agreement between the Company and the Grantee. Each
Agreement shall contain such restrictions, which may include specific
performance goals, or other terms and conditions as the Committee may, in its
discretion, determine and (without limiting the generality of the foregoing)
such Agreements may require that an appropriate legend be placed on Share
certificates.
 
  6.2 Purchase Price. The purchase price, if any, for Shares of Restricted
Stock shall be determined by the Committee, but shall not be less than the par
value per Share, except in the case of treasury Shares, for which no
 
                                      C-7
<PAGE>
 
payment need be required. Awards of Restricted Stock shall be subject to the
terms and provisions set forth below in this Section 6, unless the Committee
then determines otherwise to the extent permitted by applicable law.
 
  6.3 (a) Performance Based Restricted Stock. If the vesting of an Award of
Restricted Stock requires the satisfaction of Performance Objectives
("Performance Based Restricted Stock"), the Performance Objectives may be
expressed in terms of (i) earnings per Share, (ii) Share price, (iii) pre-tax
profits, (iv) net earnings, (v) return on equity or assets, (vi) revenues or
(vii) any combination of the foregoing. Performance Objectives may be in
respect of the performance of the Company and its Subsidiaries (which may be
on a consolidated basis), a Subsidiary or a Division. Performance Objectives
may be absolute or relative and may be expressed in terms of a progression
within a specified range. The Performance Objectives with respect to a
Performance Cycle shall be established by the Committee in order to comply
with Rule 16b-3 under the Exchange Act and Section 162(m) of the Code as
applicable.
 
  (b) Vesting and Forfeiture of Restricted Stock with Performance Objectives.
Subject to Sections 6.3(c) and 6.6(b), a Grantee shall become vested with
respect to the Shares of Performance Based Restricted Stock to the extent that
the Performance Objectives set forth in the Agreement are satisfied for the
Performance Cycle.
 
  (c) Prior to the vesting, payment, settlement or lapsing of any restrictions
with respect to any award of Performance Based Restricted Stock, the Committee
shall certify in writing that the applicable Performance Objectives have been
satisfied.
 
  6.4 Rights of Grantee. Shares of Restricted Stock granted pursuant to an
Award hereunder shall be issued in the name of the Grantee as soon as
reasonably practicable after the Award is granted provided that the Grantee
has executed an Agreement evidencing the Award, the appropriate blank stock
powers and, in the discretion of the Committee, an escrow agreement and any
other documents which the Committee may require as a condition to the issuance
of such Shares. If a Grantee shall fail to execute the Agreement evidencing a
Restricted Stock Award, the appropriate blank stock powers and, in the
discretion of the Committee, an escrow agreement and any other documents which
the Committee may require within the time period prescribed by the Committee
at the time the Award is granted, the Award shall be null and void. At the
discretion of the Committee, Shares issued in connection with a Restricted
Stock Award shall be deposited together with the stock powers with an escrow
agent (which may be the Company) designated by the Committee. Unless the
Committee determines otherwise and as set forth in the Agreement, upon
delivery of the Shares to the escrow agent, the Grantee shall have all of the
rights of a stockholder with respect to such Shares, including the right to
vote the Shares and to receive all dividends or other distributions paid or
made with respect to the Shares.
 
  6.5 Non-transferability. Until all restrictions upon the Shares of
Restricted Stock awarded to a Grantee shall have lapsed in the manner set
forth in Section 6.6, such Shares shall not be sold, transferred or otherwise
disposed of and shall not be pledged or otherwise hypothecated, nor shall they
be delivered to the Grantee.
 
  6.6 Lapse of Restrictions.
 
  (a) Generally. Restrictions upon Shares of Restricted Stock awarded
hereunder shall lapse at such time or times and on such terms and conditions
as the Committee may determine, including the satisfaction of Performance
Objectives in the case of Performance Based Restricted Stock if any. The
Agreement evidencing the Award shall set forth any such restrictions. Except
for Awards of Performance Based Restricted Stock, the Committee may accelerate
or waive any or all of the restrictions and conditions applicable to any
Award, for any reason.
 
  (b) Effect of Change in Control. Unless the Committee shall determine
otherwise at the time of the grant of an Award of Restricted Stock, the
restrictions upon Shares of Restricted Stock shall lapse upon a Change in
Control. The Agreement evidencing the Award shall set forth any such
provisions.
 
  6.7 Modification or Substitution. Subject to the terms of the Plan, the
Committee may modify outstanding Awards of Restricted Stock or accept the
surrender of outstanding Shares of Restricted Stock (to the extent the
 
                                      C-8
<PAGE>
 
restrictions on such Shares have not yet lapsed) and grant new Awards in
substitution for them. Notwithstanding the foregoing, no modification of an
Award shall adversely alter or impair any rights or obligations under the
Agreement without the Grantee's consent.
 
  6.8 Treatment of Dividends. At the time an Award of Shares of Restricted
Stock is granted, the Committee may, in its discretion, determine that the
payment to the Grantee of dividends, or a specified portion thereof, declared
or paid on such Shares by the Company shall be (i) deferred until the lapsing
of the restrictions imposed upon such Shares and (ii) held by the Company for
the account of the Grantee until such time. In the event that dividends are to
be deferred, the Committee shall determine whether such dividends are to be
reinvested in additional Shares (which shall be held as additional Shares of
Restricted Stock) or held in cash. If deferred dividends are to be held in
cash, there may be credited at the end of each year (or portion thereof)
interest on the amount of the account at the beginning of the year at a rate
per annum as the Committee, in its discretion, may determine. Payment of
deferred dividends in respect of Shares of Restricted Stock (whether held in
cash or as additional Shares of Restricted Stock), together with interest
accrued thereon, if any, shall be made upon the lapsing of restrictions
imposed on the Shares in respect of which the deferred dividends were paid,
and any dividends deferred (together with any interest accrued thereon) in
respect of any Shares of Restricted Stock shall be forfeited upon the
forfeiture of such Shares.
 
  6.9 Delivery of Shares. Upon the lapse of the restrictions on Shares of
Restricted Stock, the Committee shall cause a stock certificate to be
delivered to the Grantee with respect to such Shares, free of all restrictions
hereunder.
 
  6.10 Termination of Employment, Death or Disability.
 
  (a) Except as provided in Section 6.10(d), if the employment of a Grantee is
terminated for any reason other than death or Disability prior to the
expiration of any restrictions applicable to any Shares of Restricted Stock
then held by the Grantee, such Shares shall thereupon be forfeited immediately
by the Grantee and returned to the Company, and the Grantee shall only receive
the amount, if any, paid by the Grantee for such Restricted Stock.
 
  (b) If the employment of a Grantee is terminated as a result of death or
Disability prior to the expiration of any restrictions applicable to any
Shares of Restricted Stock then held by the Grantee, any restrictions and
other conditions pertaining to such Shares then held by the Grantee,
including, but not limited to, vesting requirements, shall immediately lapse
and such Shares shall thereafter be immediately transferable and
nonforfeitable.
 
  (c) Except for Awards of Performance Based Restricted Stock, with respect to
which the Committee has not at the time of grant provided to the contrary, if
the employment of a Grantee is terminated as a result of Retirement prior to
the expiration of any restrictions applicable to any Shares of Restricted
Stock then held by Grantee, any restrictions and other conditions pertaining
to such Shares then held by the Grantee, including, but not limited to,
vesting requirements, shall immediately lapse and such Shares shall thereafter
be immediately transferable and nonforfeitable.
 
  (d) Notwithstanding anything in the Plan to the contrary and except for
Awards of Performance Based Restricted Stock, with respect to which the
Committee has not at the time of grant provided to the contrary, the Committee
may determine, in its sole discretion, in the case of any termination of a
Grantee's employment other than for Cause, that the restrictions on some or
all of the Shares of Restricted Stock then held by the Grantee shall
immediately lapse and such Shares shall thereafter be immediately transferable
and nonforfeitable.
 
  7. ADJUSTMENT UPON CHANGES IN CAPITALIZATION.
 
  (a) In the event of a Change in Capitalization, the Committee shall
conclusively determine the appropriate adjustments, if any, to (i) the maximum
number and class of Shares or other stock or securities with respect to which
Options or Awards may be granted under the Plan, (ii) the maximum number and
class of Shares or other
 
                                      C-9
<PAGE>
 
stock or securities with respect to which Options or Awards may be granted to
any Eligible Individual during the term of the Plan, and (iii) the number and
class of Shares or other stock or securities which are subject to outstanding
Options or Awards granted under the Plan and the purchase price therefor, if
applicable.
 
  (b) Any such adjustment in the Shares or other stock or securities subject
to outstanding Incentive Stock Options (including any adjustments in the
purchase price) shall be made in such manner as not to constitute a
modification as defined by Section 424(h)(3) of the Code and only to the
extent otherwise permitted by Sections 422 and 424 of the Code.
 
  (c) If, by reason of a Change in Capitalization, a Grantee of an Award shall
be entitled to, or an Optionee shall be entitled to exercise an Option with
respect to, new, additional or different Shares of stock or securities, such
new, additional or different shares shall thereupon be subject to all of the
conditions, restrictions and performance criteria which were applicable to the
Shares subject to the Award or Option, as the case may be, prior to such
Change in Capitalization.
 
 8. EFFECT OF CERTAIN TRANSACTIONS. Subject to Sections 5.10 and 6.6(b) or as
otherwise provided in an Agreement, in the event of (i) the liquidation or
dissolution of the Company or (ii) a merger or consolidation of the Company (a
"Transaction"), the Plan and the Options and Awards issued hereunder shall
continue in effect in accordance with their respective terms, except that
following a Transaction each Optionee and Grantee shall be entitled to receive
in respect of each Share subject to any outstanding Options or Awards, as the
case may be, upon exercise of any Option or payment or transfer in respect of
any Award, the same number and kind of stock, securities, cash, property, or
other consideration that each holder of a Share was entitled to receive in the
Transaction in respect of a Share; provided, however, that such stock,
securities, cash, property, or other consideration shall remain subject to all
of the conditions, restrictions and performance criteria which were applicable
to the Options and Awards prior to such Transaction.
 
  9. INTERPRETATION. Following the required registration of any equity
security of the Company pursuant to Section 12 of the Exchange Act:
 
    (a) The Plan is intended to comply with Rule 16b-3 promulgated under the
  Exchange Act and the Committee shall interpret and administer the
  provisions of the Plan or any Agreement in a manner consistent therewith.
  Any provisions inconsistent with such Rule shall be inoperative and shall
  not affect the validity of the Plan.
 
    (b) Each Option and certain Performance Based Restricted Stock granted
  under the Plan are intended to be performance-based compensation within the
  meaning of Section 162(m)(4)(C) of the Code. The Committee shall not be
  entitled to exercise any discretion otherwise authorized hereunder with
  respect to such Options or Awards if the ability to exercise such
  discretion or the exercise of such discretion itself would cause the
  compensation attributable to such Options or Awards to fail to qualify as
  performance-based compensation.
 
  10. POOLING TRANSACTIONS. Notwithstanding anything contained in the Plan or
any Agreement to the contrary, in the event of a Change in Control, which has
been approved by the Board, which is also intended to constitute a Pooling
Transaction, the Committee shall take such actions, if any, which are
specifically recommended by an independent accounting firm retained by the
Company to the extent reasonably necessary in order to assure that the Pooling
Transaction will qualify as such, including but not limited to (i) deferring
the vesting, exercise, payment, settlement, or lapsing of restrictions with
respect to any Option or Award, (ii) providing that the payment or settlement
in respect of any Option or Award be made in the form of cash, Shares or
securities of a successor or acquirer of the Company, or a combination of the
foregoing and (iii) providing for the extension of the term of any Option or
Award to the extent necessary to accommodate the foregoing, but not beyond the
maximum term permitted for any Option or Award.
 
  11. TERMINATION AND AMENDMENT OF THE PLAN. The Plan shall terminate on the
day preceding the tenth anniversary of the date of its adoption by the Board
and no Option or Award may be granted after March 13,
 
                                     C-10
<PAGE>
 
2006. The Board may sooner terminate the Plan and the Board may at any time
and from time to time amend, modify or suspend the Plan; provided, however,
that:
 
    (a) no such amendment, modification, suspension or termination shall
  impair or adversely alter any Options or Awards theretofore granted under
  the Plan, except with the consent of the Optionee or Grantee, nor shall any
  amendment, modification, suspension or termination deprive any Optionee or
  Grantee of any Shares which he or she may have acquired through or as a
  result of the Plan; and
 
    (b) to the extent necessary for the Plan to continue to satisfy the
  applicable requirement of Rule 16b(3) promulgated under Section 16(b) of
  the Exchange Act or other applicable law, no amendment shall be effective
  unless approved by the stockholders of the Company in accordance with
  applicable law and regulations.
 
  12. NON-EXCLUSIVITY OF THE PLAN. The adoption of the Plan by the Board shall
not be construed as amending, modifying or rescinding any previously approved
incentive arrangement or as creating any limitations on the power of the Board
to adopt such other incentive arrangements as it may deem desirable,
including, without limitation, the granting of stock options otherwise than
under the Plan, and such arrangements may be either applicable generally or
only in specific cases.
 
  13. LIMITATION OF LIABILITY. As illustrative of the limitations of liability
of the Company, but not intended to be exhaustive thereof, nothing in the Plan
shall be construed to:
 
    (a) give any person any right to be granted an Option or Award other than
  at the sole discretion of the Committee;
 
    (b) give any person any rights whatsoever with respect to Shares except
  as specifically provided in the Plan;
 
    (c) limit in any way the right of the Company to terminate the employment
  of any person at any time; or
 
    (d) be evidence of any agreement or understanding, expressed or implied,
  that the Company will employ any person at any particular rate of
  compensation or for any particular period of time.
 
  14. REGULATIONS AND OTHER APPROVALS; GOVERNING LAW.
 
  14.1 Except as to matters of federal law, the Plan and the rights of all
persons claiming hereunder shall be construed and determined in accordance
with the laws of the State of Delaware without giving effect to conflicts of
laws principles thereof.
 
  14.2 The obligation of the Company to sell or deliver Shares with respect to
Options and Awards granted under the Plan shall be subject to all applicable
laws, rules and regulations, including all applicable federal and state
securities laws, and the obtaining of all such approvals by governmental
agencies as may be deemed necessary or appropriate by the Committee.
 
  14.3 The Board may make such changes as may be necessary or appropriate to
comply with the rules and regulations of any government authority, or to
obtain for Eligible Individuals granted Incentive Stock Options the tax
benefits under the applicable provisions of the Code and regulations
promulgated thereunder.
 
  14.4 Each Option and Award is subject to the requirement that, if at any
time the Committee determines, in its discretion, that the listing,
registration or qualification of Shares issuable pursuant to the Plan is
required by any securities exchange or under any state or federal law, or the
consent or approval of any governmental regulatory body is necessary or
desirable as a condition of, or in connection with, the grant of an Option or
Award or the issuance of Shares, no Options or Awards shall be granted or
payment made or Shares issued, in whole or in part, unless listing,
registration, qualification, consent or approval has been effected or obtained
free of any conditions as acceptable to the Committee.
 
                                     C-11
<PAGE>
 
  15. MISCELLANEOUS.
 
  15.1 Multiple Agreements. The terms of each Option or Award may differ from
other Options or Awards granted under the Plan at the same time, or at some
other time. The Committee may also grant more than one Option or Award to a
given Eligible Individual during the term of the Plan, either in addition to,
or in substitution for, one or more Options or Awards previously granted to
that Eligible Individual.
 
  15.2 Withholding of Taxes.
 
  (a) At such times as an Optionee or Grantee recognizes taxable income in
connection with the receipt of Shares or cash hereunder (a "Taxable Event"),
the Optionee or Grantee shall pay to the Company an amount equal to the
federal, state and local income taxes and other amounts as may be required by
law to be withheld by the Company in connection with the Taxable Event (the
"Withholding Taxes") prior to the issuance, or release from escrow, of such
Shares or the payment of such cash. In satisfaction of the obligation to pay
Withholding Taxes to the Company, the Optionee or Grantee may make a written
election (the "Tax Election"), which may be accepted or rejected in the
discretion of the Committee to have withheld a portion of the Shares then
issuable to him or her having an aggregate Fair Market Value equal to the
Withholding Taxes. Notwithstanding the foregoing, the Committee may, by the
adoption of rules or otherwise impose such other restrictions or limitations on
Tax Elections as may be necessary to ensure that the Tax Elections will be
exempt transactions under Section 16(b) of the Exchange Act.
 
  (b) If an Optionee makes a disposition, within the meaning of Section 424(c)
of the Code and regulations promulgated thereunder, of any Share or Shares
issued to such Optionee pursuant to the exercise of an Incentive Stock Option
within the two-year period commencing on the day after the date of the grant or
within the one-year period commencing on the day after the date of transfer of
such Share or Shares to the Optionee pursuant to such exercise, the Optionee
shall, within ten (10) days of such disposition, notify the Company thereof, by
delivery of written notice to the Company at its principal executive office.
 
  15.3 Effective Date. The effective date of the Plan, as amended, shall be May
14, 1998, subject only to the approval by the stockholders of the Company.
