registered class of the Company's equity securities to file initial reports of
beneficial ownership of certain equity securities of the Company and reports of
subsequent changes in ownership with the SEC and the New York Stock Exchange.
Such persons are also required by SEC regulations to furnish the Company with
copies of all Section 16(a) forms which they file relating to securities of the
Company.

                                                                               3

(1) All stock options reflected in this table were non-qualified options granted
    pursuant to the Company's stock option plans and are subject to the terms of
    such Plans. These stock options become exercisable in annual ratable
    installments on the four successive anniversary dates of the respective
    dates of grant, subject to possible acceleration in the event of the
    termination of the Named Officers' employment, a change in control of the
    Company or otherwise as provided in the Plans or other agreements.

                                                                               6

(2) Calculated based upon the aggregate of the differences between: (i) $22 5/8
    the per-share closing price of the Company's Common Stock on the New York
    Stock Exchange on February 26, 1999, the last trading day of the Company's
    1999 fiscal year, and (ii) the per-share exercise prices for the respective
    grants of stock options.

COMPENSATION OF DIRECTORS

         During fiscal 1999, directors who were not employees of the Company
were entitled to annual directors' fees at the rate of $30,000 per year, plus
$1,000 per day (other than for a day on which there was a meeting of the Board)
for attending committee or other meetings or functions relating to Company
business, plus $1,000 per day (other than a day for which such director received
the aforementioned $1,000 per diem) for any day during which such director was
required to spend more than five hours in connection with certain administrative
matters relating to the Company's business. Directors also are reimbursed for
expenses. Commencing during the second quarter of fiscal 1999, directors of the
Company were entitled, under the Company's 1998 Non-Employee Directors' Stock
Election Plan, to elect to receive all or a portion of their directors' fees in
the form of shares of Common Stock of the Company valued at fair market value.
All of the five non-employee directors (Messrs. Dewey, Donoho and Ruys, Lord
Moore and General Paige) elected to receive all of their fiscal 1999 directors'
fees accruing after June 1, 1998 in the form of Company shares.

         From time to time directors provide special consulting or other
services for the Company for which they receive additional compensation. During
fiscal 1999, the following amounts in addition to the annual directors' fee and
committee meeting fees were paid to directors in cash for special services as
directors: Messrs. Dewey, Donoho and Ruys - $5,000 each; Lord Moore - $38,000;
and General Paige - $8,000.

         The Company's 1996 Non-Employee Directors' Stock Option Plan (the "1996
Plan") provided for automatic grants to each non-employee director, shortly
following each of the 1996, 1997 and 1998 Annual Meetings, of a nonqualified
stock option for 10,000 shares of Common Stock with a per share exercise price
equal to the fair market value of a share of Common Stock on the date of grant.
Such options become exercisable approximately one year following the date of
grant and extend for a five-year term. Pursuant to the 1996 Plan, on July 16,
1998, each of the five non-employee directors was granted such a 10,000 share
option with an exercise price of $32.09 per share. The 1996 Plan expired by its
terms on December 31, 1998. Lord Moore also held 3,000 stock units, granted
under the Company's 1992 Outside Directors' Stock Unit Plan (the "DSU Plan") in
1995, which stock units vested at the time of the 1998 Annual Meeting. Pursuant
to the terms of the DSU Plan, Lord Moore received $70,463 from the Company in
fiscal 1999 to offset taxes incurred by him in connection with the 1998 vesting
of these stock units. No other directors held stock units under the DSU Plan
during fiscal 1999 and that Plan terminated in 1996.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         During fiscal 1999, decisions regarding executive compensation were
made primarily by the Compensation Committee, subject to the terms of applicable
employment agreements and ratification by the full Board in certain
circumstances. Mr. O'Connor, Chairman, President and Chief Executive Officer,
participated in certain deliberations of the Compensation Committee concerning
executive officer compensation.

                                                                               7
<PAGE>   8
         Messrs. Dewey, Donoho, Ruys, and General Paige were members of the
Compensation Committee during various periods of fiscal 1999. Mr. Ruys replaced
Mr. Donoho on the Committee during the year.

EMPLOYMENT -- SEVERANCE AGREEMENTS AND ARRANGEMENTS

         Mr. O'Connor originally entered into an employment agreement with the
Company in October 1994, which agreement was amended and restated in July 1997
in connection with his promotion to Chief Executive Officer. The term of Mr.
O'Connor's amended and restated employment agreement commenced on July 14, 1997
and continues until his death, disability, retirement from active employment
(with the consent of the Board or in accordance with Company policy),
resignation or discharge. The agreement, as currently in effect, provides for an
annual base salary of $600,000 (increased annually based upon the Consumer Price
Index and otherwise in the discretion of the Board or the Compensation
Committee), an annual performance bonus of up to a maximum of six times his
then-current salary, and life insurance and various other benefits (including,
but not limited to, medical coverage for Mr. O'Connor and his family, certain
club memberships, spousal travel, certain professional services, use of
automobile, and certain fringe and other benefits identified in the notes to the
Summary Compensation Table above). The agreement provides that Mr. O'Connor's
performance bonus is to be determined using a matrix of reasonable quantitative
metrics established by and in the reasonable discretion of the Compensation
Committee.

         Under the agreement, if Mr. O'Connor's employment with the Company is
terminated by reason of his death, retirement from active employment (with
consent of the Board or in accordance with the retirement policies of the
Company), discharge by the Company for Cause or resignation (other than for Good
Reason), Mr. O'Connor (or his estate, as the case may be) is entitled to his
base salary, benefit and bonus amounts, if any, accrued through the date of
termination, and, in the case of retirement from active employment after age 65,
comprehensive medical coverage for Mr. O'Connor and eligible family members and
certain term life insurance coverage. If Mr. O'Connor's employment is terminated
by reason of disability, discharge by the Company without Cause or by reason of
Mr. O'Connor's resignation for Good Reason, he is entitled to receive, in
addition to all salary, bonuses and benefits accrued through the date of
termination, an amount equal to the sum of three times the average of his base
salary, bonuses and certain perquisites for the prior three fiscal years, plus
$1,500,000. In addition, in the event of termination of his employment for any
of the aforesaid reasons, Mr. O'Connor is entitled to post-employment life
insurance for up to three years and comprehensive medical coverage for a minimum
of three years after such termination. The agreement further provides in such
circumstances for the payment to him of an amount equal to the sum of the
present value of all benefits accrued by him under any non-qualified Company
plan (including the Supplemental Executive Retirement Plan) and three times the
average benefits of, or Company contributions to, over the three previous fiscal
years, under all Company plans.

         Mr. O'Connor's agreement also provides that irrespective of the reason
for his termination of employment with the Company, he may not compete with the
Company for three years after the date of such termination.

         If Mr. O'Connor's employment terminates within twenty-four months after
a change in control of the Company (including as a result of Mr. O'Connor's
voluntary resignation not earlier than six months, and not later than one year,
following the change in control, but not including his normal retirement), then
specific provisions apply in lieu of the provisions described above. In such
event, Mr. O'Connor is entitled to receive, in addition to his salary, benefits
and bonus amounts, if any, accrued through the date of termination, an amount
equal to 2.99 times the sum of his then-current base salary, most recent
performance bonus (or, if higher, the performance bonus most recently awarded to
him prior to the

                                                                               8

change in control) and certain perquisites and other amounts. In addition, in
the event of termination of Mr. O'Connor's employment following a change in
control, the Company is obligated to provide him with life insurance and
comprehensive medical coverage after termination and to pay him the present
value of all benefits accrued for him under any non-qualified Company plan and
an amount equal to four times the average (over the previous three fiscal years)
accrued benefit under, or Company contributions to, all qualified plans. The
agreement further requires the payment to Mr. O'Connor of an amount equal to any
excise tax due as a result of a payment or benefit constituting a "parachute
payment" within the meaning of Section 280G of the Internal Revenue Code of
1986, as amended, together with amounts necessary to gross-up Mr. O'Connor for
any taxes due thereon.

         A "change in control" generally is deemed to have occurred under Mr.
O'Connor's agreement if any of the following occurs: (i) individuals comprising
the Board of Directors of the Company at the beginning of any consecutive
twenty-four month period cease (other than due to death or with the approval of
a majority of such directors) to constitute a majority of the Board; (ii) any
"person" or "group" (as defined under the Securities Exchange Act of 1934, as
amended, the "Exchange Act", becomes a "beneficial owner" (as defined under the
Exchange Act), directly or indirectly, of more than 30% of the combined voting
power of the Company's then-outstanding common equity securities; or (iii) the
stockholders of the Company approve a definitive agreement (A) for the merger of
the Company into or with another corporation (unless the directors of the
Company immediately prior to the merger constitute a majority of the directors
of the surviving corporation or the stockholders of the Company immediately
prior to the merger own 50% or more of the combined voting power of the
surviving corporation) or (B) for the sale or disposition of all or
substantially all of the assets of the Company.

         "Good Reason" is defined in Mr. O'Connor's agreement to mean: (i) the
assignment of duties that are materially inconsistent with the scope of his
stated duties; (ii) the Company's failure to pay him any amounts vested and due
under his employment agreement or any other Company plan or policy; (iii) a
reduction in benefits to him or a material adverse change in the terms or
conditions under which amounts are payable; (iv) a reduction in Mr. O'Connor's
title or duties; (v) a breach of the Company's obligations not to relocate him
without his consent; (vi) in the case of any merger or similar transaction
involving the Company, the failure by the Company to obtain an agreement
reasonably satisfactory to Mr. O'Connor from a successor to the Company to
assume his employment agreement; or (vii) any material breach by the Company of
the agreement. "Cause" is defined to mean: (i) any willful and continuing
failure to substantially perform employment duties with a material adverse
effect upon the Company; (ii) any engagement in serious misconduct which is
injurious to the Company; (iii) any willful and continuing material breach of
the agreement, including with respect to confidentiality, protection of
intellectual property or non-competition; (iv) conviction of a crime involving
fraud, misrepresentation, gambling or a felony with a material adverse effect
upon the Company; or (v) habitual intoxication or abuse of drugs or controlled
substances.

         Mr. Nowick has an employment agreement with the Company dated as of
January 15, 1999 and effective July 11, 1997. The agreement provides for: an
annual base salary of $360,000 (which is subject to increase each March 1,
commencing in 1999, to reflect any increase in the Consumer Price Index); an
annual management incentive bonus of up to a maximum of two times his base
salary (based upon the attainment of personal and Company performance
objectives); a contribution by the Company of $364,933 to the Income Deferral
Plan for Mr. Nowick's account; and various other benefits, including, but not
limited to, home buyout option, use of automobile, medical coverage for Mr.
Nowick and his family, tax preparation and participation in the Company's stock
option, perquisites and other benefit plans for senior executives. In the
agreement, Mr. Nowick agrees, among other things, not to compete with the
Company in the lottery and gaming business for three years, or in any other
business for one year, following termination of his employment.

                                                                               9
<PAGE>   10
         The initial term of Mr. Nowick's agreement ends February 28, 2001. On
March 1, 2001 and on each subsequent March 1, the term of the agreement is to be
automatically extended for one year unless at least 180 days prior to such date
either the Company or Mr. Nowick has notified the other that it or he does not
wish to extend the term. If the term of Mr. Nowick's employment is terminated by
death, retirement, discharge for Cause or resignation other than for Good
Reason, he is generally entitled to receive his then-current base salary and
benefits accrued up to the date of termination or as otherwise provided by the
terms of the specific benefit plans in which he participates. If Mr. Nowick's
employment term is terminated as a result of his disability, discharge without
Cause or resignation for Good Reason, the Company is required to continue: (i)
his then-current base salary for three years following such termination, or
until his earlier death, and (ii) his life insurance and medical coverage for
one year following such termination. With certain exceptions, the terms "Change
in Control," "Good Reason" and "Cause" in Mr. Nowick's employment agreement are
defined in generally the same manner as such terms are defined in Mr. O'Connor's
employment agreement as described above.

         Notwithstanding the foregoing, if a Change in Control occurs during the
term of Mr. Nowick's employment, his employment agreement provides that it will
terminate and the terms and conditions of his employment will be governed by the
terms of the Change in Control agreement, which is described in the fifth
paragraph below.

         Mr. Chambrello resigned as an executive officer of the Company,
effective July 31, 1998, and as an employee of the Company, effective December
31, 1998. Pursuant to an employment transition agreement with the Company, Mr.
Chambrello received the salary, bonus and benefits for fiscal 1999 reflected in
the Summary Compensation Table above. In addition, the Company sold to him for a
nominal consideration his company automobile, a company-owned fax machine and
two company-owned telephones, and agreed to continue to provide him with medical
coverage, life insurance and tax preparation services, as well as outplacement
services, through calendar year 1999. The agreement also provided for mutual
releases of claims and liabilities, except for certain continuing
indemnification obligations, and Mr. Chambrello agreed to continue to be bound
by certain restrictive covenants.

         Mr. Gay had an employment agreement with the Company at the time of his
resignation from the Company in March 1998. The agreement provided for a minimum
annual base salary of $275,000, eligibility for an annual management bonus,
company benefits and perquisites provided generally to other Company officers
and specified commissions. Under his employment agreement, Mr. Gay was entitled
to receive quarterly commissions equal to one-half of one percent (0.5%) of Net
Revenue derived by the Company from the sale of mutually-agreed gaming products
and services in specified states. In addition, he was entitled to receive sales
commissions based upon a variable percentage (ranging from forty one-
thousandths of one percent (0.040%) to one-tenth of one percent 0.10%) of all
Net Revenue derived by the Company from the sale of mutually-agreed gaming
products and services. The percentage of Net Revenue to which Mr. Gay was
entitled with respect to the latter element of his commission arrangement was
based upon the percentage of "wins" enjoyed by the Company for a fiscal year
(i.e., Company contracts entered into with, or extended by, customers during
such fiscal year) as a percentage of the total number of opportunities for such
fiscal year.

         The agreement defined "Net Revenue" as the invoice price (for sales) or
gross revenues (for goods or services provided on a percentage basis), less
liquidated damages, refunds, returns, taxes (other than income taxes), discounts
and other price adjustments and certain costs. Mr. Gay's employment agreement
could be terminated by either Mr. Gay or by the Company upon thirty days'
notice. In the event that the Company terminated the agreement (other than for
cause) or Mr. Gay terminated the agreement as the result of a reduction of his
responsibilities and income potential, the Company was obligated to pay Mr. Gay
a lump sum severance amount equal to his then-current annual base salary. In the
case of termination by the Company of the employment agreement for cause or
termination by Mr.

                                                                              10
<PAGE>   11
Gay other than as a result of a reduction in his responsibilities and income
potential, the Company had no obligations to make any payments whatsoever to Mr.
Gay upon termination of his employment except as to such amounts accrued to him
through the date of termination. Under Mr. Gay's employment agreement, "cause"
was defined to include negligent performance of employment duties resulting in
harm to the Company, refusal to perform employment duties, conviction of a
felony or other crime involving fraud or certain dishonesty, unauthorized acts
resulting in personal enrichment, certain acts constituting misconduct or
dereliction of duty, any other material breach of the employment agreement or
death.

         In March 1998, the Company and Mr. Gay entered into a severance
agreement pursuant to which Mr. Gay resigned as an employee and officer of the
Company. The Company agreed to pay Mr. Gay all accrued and unpaid commissions
due him through the date of his resignation under his employment agreement and,
in addition, a lump-sum payment with respect to post-employment severance of
$3,600,000. In addition, the Company agreed to consider Mr. Gay for a management
bonus for fiscal 1998 (and ultimately paid him a fiscal 1998 management bonus of
$285,000), allowed Mr. Gay to continue to use his Company-owned automobile for
three years following termination and provided certain other benefits to him.
The agreement also provided for mutual releases of claims and liabilities,
except for certain continuing indemnification obligations on the part of the
Company, and Mr. Gay agreed not to compete with the Company in certain
activities for one year following termination.

         The Company does not presently have formal employment agreements with
the other current Named Officers: Messrs. Sauser, Stanford and Sweitzer,
although the Company has entered into agreements with these executives (and with
certain other executives, including Mr. Nowick) with respect to employment
arrangements in the event of a "Change in Control" of the Company. These
agreements provide for three-year employment terms for the covered executives
commencing upon the date a change in control occurs (or earlier in certain
circumstances where actions are taken in anticipation of a change in control).
During each such employment term, the covered executive is to be employed in a
position at least equal in all material respects with the highest position held
by such executive during the six months immediately preceding the change of
control and will be entitled to a base annual salary, annual bonus and benefits
in values and amounts at least equal to those provided by the Company to the
executive immediately prior to the commencement of the term of employment. In
addition, upon the occurrence of a change in control, all benefits accrued by
the executive under all non-qualified Company plans (including the Supplemental
Retirement Plan) will become fully vested and shall be contributed to a rabbi
trust for the benefit of the covered executive, and all options held by the
executive will become fully vested and exercisable by the executive.

         If an executive's employment is terminated during the term of
employment (including as a result of resignation by executive without Good
Reason), such agreement provides, with respect to the year in which his
employment is terminated, that he will receive his base salary, bonus, and other
compensation and benefits through the date of termination in accordance with
Company policy in effect immediately prior to the commencement of the term of
employment. In the event that a covered executive's employment is terminated
(other than for Cause) or such executive resigns for Good Reason, the Company is
obligated to pay an amount equal to 2.99 times the sum of: (i) his then-current
annual base salary; (ii) the total cash bonus received by the executive during
the most recent full fiscal year; plus (iii) the maximum amount allowable under
the Executive Perquisite Program during the most recent calendar year. In
addition, the covered executive (together with his beneficiaries and dependents)
will become fully vested in and continue to participate for up to three years at
no cost to the executive in all Company life insurance and welfare plans on
terms at least as favorable to executive as in effect immediately prior to
termination. In addition, the executive will be entitled to receive the sum of
all benefits accrued under the non-qualified plans plus the product of 2.99
times the average benefit accrued and/or contributions made to such
non-qualified plans over the preceding three years. Such agreements further
provide for the payment to the covered executives of amounts equal to any excise
tax due as any payment or benefit

                                                                              11
<PAGE>   12
constituting a "parachute payment" within the meaning of Section 280G of the
Code, together with amounts necessary to gross-up such executives for any taxes
due with respect thereto. With certain exceptions, the terms "Change in
Control," "Good Reason" and "Cause" are defined in these agreements in generally
the same manner as the corresponding terms are defined in Mr. O'Connor's
employment agreement as described above.

         Under the terms of the Company's option plans and various agreements,
the exercisability of outstanding stock options may accelerate in the event of a
change in control or termination of employment.

         The Company has two defined contribution 401(k) retirement savings and
profit sharing plans (the "Plans") covering (subject to applicable time of
service requirements) substantially all full-time employees in the United
States, including the Named Officers. Under these Plans, an eligible employee
may elect to defer receipt of a portion of base pay for each year in which case
the Company will contribute this amount on the employee's behalf to the Plans
and also will make a matching contribution equal to 50% of the amount that the
employee has elected to defer, up to a maximum matching contribution of 2 -1/2%
of the employee's base pay. The Company, in its discretion, may contribute
additional amounts to the Plans on behalf of employees based upon its profits
for a given fiscal year. Participants are 100% vested at all times in their
entire account balance in the Plans. Benefits under the Plans generally will be
paid to participants upon retirement or in certain other limited circumstances.
The Company also has a Supplemental Retirement Plan which is a defined
contribution plan that provides to certain key employees, including the Named
Officers, additional retirement benefits. The Company, at its discretion, may
contribute additional amounts to the plan on behalf of such key employees equal
to the percentage of profit sharing contributions contributed for the calendar
year, multiplied by each such employee's compensation (as defined) for such
year. See "Summary Compensation Table," above.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         During fiscal 1995, the Company implemented a loan program under which
employees whose restricted stock units or rights granted to them by the Company
become taxable compensation to them can obtain loans from the Company to assist
them in paying applicable federal and state income tax withholding. During
fiscal 1999, Mr. O'Connor repaid a previous loan of $21,161 made to him pursuant
to this program, and the Company made another loan of $10,496 to Mr. O'Connor
with respect to the vesting of restricted stock rights granted to him in 1994.
This latter loan, bearing interest at 7.1%, remained outstanding as of February
27, 1999.

         During fiscal 1995, the Company, pursuant to the terms of its
employment agreement with Mr. O'Connor, made loans to him to enable him to
retire certain third-party indebtedness. The loans to Mr. O'Connor consisted of
$400,000 under a line of credit arrangement which bore no interest and which was
repaid in full during fiscal 1997, and $500,000 bearing interest at the rate of
6.0% per annum, which was repayable in full on or before November 1, 1999.
During fiscal 1998, the Company extended the due date of the $500,000 loan to
January 1, 2000 and agreed to forgive the principal amount of such loan in four
installments of $125,000 each on August 1, 1997 and on January 1, 1998, 1999 and
2000. As of February 27, 1999, the outstanding amount of this loan, including
interest, was approximately $126,973.

         Current and former officers and directors of the Company are parties to
indemnification agreements with the Company providing for (and the By-Laws of
the Company also provide for) advancement of expenses and their indemnification
by the Company against certain liabilities (including legal fees and expenses)
incurred in legal proceedings or otherwise in connection with their present or
past status as an officer or director of the Company. Certain legal proceedings
and governmental investigations have involved both the Company and one or more
of its former executive officers. During fiscal 1999, the Company paid an
aggregate of approximately $348,000 in attorneys' fees and various other
expenses pursuant to these indemnification agreements and obligations in
connection with such matters directly or indirectly involving former executive
officers. Most of this related to the libel suit in the U.K. by Richard Branson
against Guy B. Snowden (the Company's former Chairman), the Company and its
press secretary, and Mr. Snowden's cross libel claim against Mr. Branson. This
litigation resulted in a verdict and judgment on February 2, 1998, in favor of
Mr. Branson and against Mr. Snowden and the Company, essentially upholding Mr.
Branson's assertion that Mr. Snowden had attempted to bribe Mr. Branson in 1993
not to bid on the U.K. Lottery contract. Mr. Snowden has appealed the verdict
and judgment against him. Mr. Snowden resigned as a director and executive
officer of the Company on February 3, 1998, prior to the beginning of fiscal
1999. No amounts were paid during fiscal 1999 with respect to current executive
officers of the Company.
