values on the common stock's last sale price on the business day
immediately preceding the date of grant, as reported on the New York
Stock Exchange. Actual gains, if any, on stock option exercises will
depend upon the future performance of our common stock's price, which
will affect all shareholders proportionately.

Incentive Plan. Each option expires upon the earlier of three months after

DIRECTOR COMPENSATION

Directors who are also MAXIMUS employees do not receive additional
compensation for their services as directors. Outside directors are paid a
$30,000 annual retainer and a fee of $2,500 for each day of board or
committee meetings in which they participate. Directors who are entitled to
directors' fees may elect to receive all or a portion of their cash fees in
stock options granted under our 1997 Equity Incentive Plan, valued using the
Black-Scholes option pricing method. For fiscal 2001, all of our outside
directors elected to receive their annual retainers in the form of stock
options. Pursuant to these elections, Mr. Brown, Mr. Pond and Governor
Thompson each received options to purchase 2,073 shares of our common stock
at an exercise price of $35.00 per share. For fiscal 2001, Mr. Pond and
Governor Thompson also elected to receive all of their meeting attendance
fees in the form of stock options. Pursuant to these elections, Mr. Pond
received options to purchase 1,720 shares of our common stock at exercise
prices ranging from $29.31 to $46.03 per share, and Governor Thompson
received options to purchase 688 shares of our common stock at exercise
prices ranging from $35.00 to $46.03 per share. For fiscal 2001, we paid Mr.
Brown $25,000 in meeting attendance fees. During our 2001 fiscal year, Mr.
Brown and Mr. Pond also received special option grants in appreciation for
their service to us, in the following amounts: Mr. Brown received options to
purchase 1,500 shares of our common stock at an exercise price of $32.15 per
share; Mr. Pond received options to purchase 4,000 shares of our common stock
at exercise prices ranging from $32.15 to $33.95 per share.

Any director who is not a MAXIMUS employee is eligible to participate in
our 1997 Director Stock Option Plan. Options under the Director Stock Option
Plan are automatically granted to an eligible director upon the election or
re-election of the director. Under the plan, each option consists of 5,000
shares of common stock for each year of the term of office to which the
director is elected or re-elected, with any period of term of office less
than a year deemed a full year. The option becomes exercisable for 5,000
shares immediately upon grant and, if the grant is for more than 5,000
shares, then it also becomes exercisable for an additional 5,000 shares at
each subsequent annual shareholders meeting during which the optionee is an
eligible director and shares remain unexercisable under the option. Options
granted under the Director Stock Option Plan have a ten-year term. The
exercise price for each option is equal to our common stock's last sale price
on the trading day immediately preceding the date of grant, as reported on
the New York Stock Exchange. Currently, the only eligible directors are
Messrs. Brown, Pond and Thompson.

EXECUTIVE EMPLOYMENT AGREEMENTS

COMPENSATION. Dr. Mastran, Mr. Davenport, Mr. Grissen and Mr.

initial base salary at $25,000 per month. Mr. Grissen's salary is reviewed

employment agreement. Mr. Hogan does not have an employment agreement with

breaches any material duty or obligation to us or engages in other proscribed
conduct.

OTHER TERMS. Mr. Grissen's employment agreement provides that he will
not compete with us and will maintain our trade secrets in strict confidence.
Although now expired, our employment agreements with Dr. Mastran, Mr.
Davenport and Mr. Beliveau contain provisions which survive the expiration of
the agreements which similarly limit these officers from engaging in certain
competitive activities and require these officers to maintain the

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT.

SECURITY OWNERSHIP OF MANAGEMENT AND FIVE PERCENT OWNERS

The following table shows the number of shares of common stock
beneficially owned as of January 2, 2002 (unless otherwise indicated), by (i)
the only persons known by us to own more than five percent of our outstanding
shares of common stock, (ii) our directors and the nominees for director,
(iii) the executive officers named in the Summary Compensation Table
contained in this report and (iv) all of our directors and executive officers
as a group.

The number of shares beneficially owned by each holder is based upon
the rules of the Securities Exchange Commission. Under SEC rules, beneficial
ownership includes any shares over which a person has sole or shared voting
or investment power as well as shares which the person has the right to
acquire within 60 days by exercising any stock option or other right.
Accordingly, this table includes shares that each person has the right to
acquire on or before March 3, 2002. Unless otherwise indicated, to the best
of our knowledge, each person has sole investment and voting power (or shares
that power with his or her spouse) over the shares in the table. By including
in the table shares that he or she might be deemed beneficially to own under
SEC rules, a holder does not admit beneficial ownership of those shares for
any other purpose.

To compute the percentage ownership of any shareholder or group of
shareholders in the following table, the total number of shares deemed
outstanding includes 23,179,820 shares that were outstanding on January 2,
2002, plus any shares that holder or group of holders could acquire upon
exercising any options held by that holder or group of holders that are
exercisable on or before March 3, 2002.
