reports of ownership and changes in ownership of such securities with the

than ten percent shareholders are required by SEC regulations to furnish the
Company with copies of all Section 16(a) forms they file.

amended Form 4 for August 1999 in April 2000. Based solely on review of the

EMPLOYMENT CONTRACTS

         In January 1999, the Company entered into a three year employment

to serve the Company as Chief Executive Officer. Pursuant to such agreement, Mr.
Stevenson receives an annual base salary of $250,000 and is eligible for an
annual bonus of up to 25% of his base salary as determined by the Company's
Board of Directors. In addition, Mr. Stevenson is eligible for an annual bonus
of up to 25% of his base salary, the exact amount to be determined pursuant to a

Board of Directors. Pursuant to such agreement, the Company paid Mr. Stevenson
no bonus in Fiscal 1999. Upon either a termination of Mr. Stevenson's employment
"without cause," Mr. Stevenson is entitled to receive the greater of his base

         Pursuant to his previous employment agreement with the Company, dated
February 1996, Mr. Stevenson was granted 300,000 options to purchase shares of
the Company's Common Stock at $7.50 per share. Fifty thousand (50,000) of such

pro-rata basis beginning February 15, 1997. The exercise price of such stock
options were repriced in October 1996 to $4.75 per share and were repriced in
December 1998 to $1.00 per share. In September 1999, Mr. Stevenson was also
granted, contingent upon the consummation of the Merger with nMortgage, Inc.,
options to purchase up to 200,000 shares of the Company's Common Stock at
$2.0625 per share.

         In October 1998, the Company and Barrett V. Johnson entered into a two
year employment agreement pursuant to which Mr. Johnson serves the Company as
President


                                       4

and Chief Operating Officer. Pursuant to the employment agreement, Mr. Johnson
receives an annual base salary of $180,000 and is eligible to receive an annual
bonus as determined by the Compensation Committee of the Company's Board of
Directors. Mr. Johnson received no bonus in Fiscal 1999. Upon termination
"without cause" Mr. Johnson is entitled to payment of his base salary for a
period of twelve months. Mr. Johnson has agreed not to compete with the Company
while employed by the Company and for a period of twelve months following
termination of such employment.

         Mr. Johnson was also granted 50,000 options pursuant to such agreement
to purchase shares of the Company's Common Stock at $2.00 per share. These
options were repriced in December 1998 to $1.125 per share. Ten thousand
(10,000) of such options vested October 1, 1998, and the balance of such options
vest over five years on a pro-rata basis beginning October 1, 1999. In September
1999, Mr. Johnson was also granted, contingent upon the consummation of the
Merger with nMortgage, Inc., options to purchase up to 50,000 shares of the
Company's Common Stock at $2.0625 per share.

DIRECTOR COMPENSATION

         Directors who are not employees of the Company are paid an annual fee
of $10,000, $1,000 for each Board meeting and $500 for each committee meeting
they attend, provided that the maximum paid to such director per day will be the
greater amount due for any single meeting in the case of multiple meetings

Option Plan pursuant to which 100,000 shares were reserved for issuance.
Pursuant to the 1997 Director Stock Option Plan, the Company has issued in April
1999, 20,000 options to each of Ronald M. Zideck, Ronald A. Johnson and Leo V.
Seevers at an exercise price of $1.00 per share. Five thousand of such options
vested immediately and the balance vest on a pro-rata basis on the first, second
and third anniversaries of the date of grant. An additional 5,000 options to
purchase shares of the Company's Common Stock will be granted annually to each
Director beginning in the fourth year that they serve as a director of the
Company. Directors who are employees of the Company are not paid fees or
additional remuneration for service as members of the Board or its Committees.
Options to purchase up to 50,000 shares of the Company's Common Stock were also
granted to each of the Non-Employee directors in September, 1999, contingent
upon consummation of the Merger with nMortgage, Inc. at $2.0625 per share.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         The Company's Compensation Committee presently consists of Messrs.
Zideck and Seevers, who have served in such capacity since the 1999 Annual
Shareholders Meeting. Lyle Berman, who resigned as a Director of the Company in
June, 1999, served on the Compensation Committee through June, 1999. Mr. Berman
is Chairman of the Board of Lakes Gaming, Inc.

BOARD COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION


                                       5
<PAGE>   8

         Decisions on compensation of the Company's executives generally have
been made by the Compensation Committee of the Board of Directors. Each member
of the Compensation Committee is a non-employee director. All decisions by the
Compensation Committee relating to the compensation of the Company's executive
officers are reviewed by the full Board of Directors. Pursuant to rules designed
to enhance disclosure of the Company's policies toward executive compensation,
set forth below is a report prepared by the Compensation Committee addressing
the compensation policies for the Company for the year ended December 31, 1999,
as they affected the Company's executive officers.

         COMPENSATION COMMITTEE

         The Compensation Committee's executive compensation policies are
designed to provide competitive levels of compensation that integrate pay with
the Company's annual objectives and long-term goals, reward above-average
corporate performance, recognize individual achievements, and assist the Company
in attracting and retaining qualified executives. Executive compensation is set
at levels that the Compensation Committee believes to be consistent with others
in the Company's industry.

         EXECUTIVE OFFICER COMPENSATION

         There are three elements in the Company's executive compensation
program, all determined by individual and corporate performance.

      *  Base salary compensation
      *  Annual incentive compensation
      *  Stock options

         Total compensation opportunities are competitive with those offered by
employers of comparable size, growth and profitability in the Company's
industry.

         CASH COMPENSATION

         Base salary compensation is determined by the potential impact the
individual has on the Company, the skills and experiences required by the job,
and the performance and potential of the incumbent in the job. In the case of
each of Edward G. Stevenson, the Chief Executive Officer and Chief Financial
Officer, and Barrett V. Johnson, the President and Chief Operating Officer, the
base compensation is governed pursuant to such executive's employment agreement
with the Company.

         Annual incentive compensation for executives of the Company is based
primarily on corporate operating earnings and revenue growth and the Company's
positioning for future results, but also includes an overall assessment by the
Compensation Committee of executive management's performance, as well as market
conditions. No cash bonuses were paid to the Company's executive officers in
Fiscal 1999.



                                       6
<PAGE>   9

         STOCK OPTIONS

         Awards of stock grants under the Company's 1992 Stock Option and
Compensation Plan (the "1992 Plan") are designed to promote the identity of
long-term interests between the Company's executives and its shareholders and
assist in the retention of executives. The Plan also permits the Committee to
grant stock options to key personnel. Options become exercisable based upon
criteria established by the Company. In October 1998, the Board also adopted the
1998 Non-Executive Stock Option Plan (the "1998 Plan") pursuant to which 200,000
shares of Common Stock were reserved for issuance for grants to Company
employees who are not executive officers of the Company. In 1999, the Board
approved an increase in the number of shares reserved for issuance under the
1998 Plan to an aggregate of 492,950.

         In September 1999, the Company issued options to purchase 200,000 and
50,000 shares of the Company's Common Stock to Messrs. Stevenson and Johnson,
respectively, at a price of $2.0625, subject to the consummation of the Merger.
The Compensation Committee believes that the issuance of such options is
appropriate for the additional services provided by such executives in
connection with the Merger and Gaming Asset Divestiture.

         The Compensation Committee surveys employee stock option programs of
companies with similar capitalization to the Company prior to recommending the
grant of options to executives. While the value realizable from exercisable
options is dependent upon the extent to which the Company's performance is
reflected in the market price of the Company's Common Stock at any particular
point in time, the decision as to whether such value will be realized in any
particular year is determined by each individual executive and not by the
Compensation Committee.

         The Compensation Committee believes that stock options are a critical
component of the compensation offered by the Company to promote long-term
retention of key employees, motivate high levels of performance and recognize
employee contributions to the success of the Company.

         CEO COMPENSATION

         Pursuant to an employment agreement with the Company, the Company pays
Mr. Stevenson a base salary of $250,000

         To date, no executive officer of the Company has received compensation
that exceeds $1 million per year.

                                                              Ronald R. Zideck
                                                              Leo V. Seevers

         The Securities and Exchange Commission requires that the Company
include in this Report a line-graph presentation comparing cumulative, five-year
return to the Company's shareholders (based on appreciation of the market price
of the Company's Common Stock) on an indexed basis with (i) a broad equity
market index and (ii) an appropriate published industry or line-of-business
index, or peer group index constructed by the Company. The following
presentation compares the Company's Common Stock price in the period from
December 31, 1994 to December 31, 1999, to the S&P 500 Stock Index and to a
"peer group" index created by the Company over the same period. The "peer group"
index consisted of the common stock of: Acres Gaming, Inc., Alliance Gaming,
Casino Data Systems, International Game Technology, Mikohn Gaming Corp., Shuffle
Master, Inc. and WMS Industries. The presentation assumes that the value of an
investment in each of the Company's Common Stock, the S&P 500 Index, and the
peer group index was $100 on December 31, 1994, and that any dividends paid were
reinvested in the same security.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         On March 5, 1999, the Company and Wayne Mills ("Mills"), who was a
director of the Company from July 22, 1999 until September 15, 1999, entered
into a Stock Redemption Agreement pursuant to which the Company agreed to redeem
400,000 shares of the Company's Common Stock beneficially owned by Mills (the
"Mills Redemption") in exchange for a convertible note (the "Mills Note") and a
warrant to acquire 50,000 shares of Common Stock (the "Warrant"). Prior to the
Mills Redemption, Mills beneficially owned in excess of 5% of the Company's
outstanding Common Stock. The Company's Board of Directors believed it would
improve the Company's ability to obtain timely licensing in certain key gaming
jurisdictions if Mills beneficially owned 4.9% or less of the Company's
outstanding Common Stock.

         Pursuant to the Mills Redemption, the Company issued the Mills Note
with a principal amount of $437,500, convertible into Common Stock at $1.09375
per share, the closing sales price of the Company's Common Stock on the day
immediately prior to the date of the consummation of the Mills Redemption. The
Mills Note became convertible on March 5, 2000 and is unsecured. The Company may
require conversion of all or a portion of the principal amount of the Mills Note
after March 5, 2000. Principal and interest on the Mills Note, which is five
percent (5%) per annum, is due March 5, 2004.

         The Warrant has a term of three years and an exercise price of $1.09375
per share, the closing sales price of the Company's Common Stock on the date of
the consummation of the Mills Redemption. Neither the Mills Note may be
converted nor the Warrant exercised if, immediately following such conversion or
exercise, as the case may be, Mills would beneficially own in excess of 4.9% of
the Company's outstanding Common Stock. The Mills Note has "piggyback"
registration rights that require the Company to register the shares issuable
upon conversion of the Mills Note in the event that the Company files certain
types of registration statements with the Securities and Exchange Commission.
Pursuant to similar "piggy-back" registration rights, the shares issuable upon
exercise of the Warrant were registered on Registration Statement on Form S-3
(Registration No. 333-84413) filed with the Securities and Exchange Commission
on August 1, 1999, and amended by Amendment No. 1 to Form S-3 filed on September
23, 1999.

         On April 21, 1999, the Company and Lakes Gaming, Inc. ("Lakes") entered
into a Stock Redemption Agreement pursuant to which the Company agreed to redeem
700,000


                                       10
<PAGE>   13

shares of the Company's Common Stock beneficially owned by Lakes (the "Lakes
Redemption") in exchange for a convertible note (the "Lakes Note") and a warrant
to acquire 87,500 shares of Common Stock (the "Lakes Warrant"). Lyle Berman,
then a director and shareholder of the Company, is Chairman of the Board and a
significant shareholder of Lakes. Prior to the Lakes Redemption, Lakes
beneficially owned 15.2% of the Company's outstanding Common Stock. The
Company's Board of Directors believed it would improve the Company's ability to
obtain timely licensing in certain key gaming jurisdictions if Lakes
beneficially owned 4.9% or less of the Company's outstanding Common Stock. Mr.
Berman resigned as director of the Company in June 1999.

         Pursuant to the Lakes Redemption, which was consummated April 22, 1999,
the Company issued the Lakes Note with a principal amount of $875,000,
convertible into Common Stock at $1.25 per share, the closing sales price of the
Company's Common Stock on the day immediately prior to the date of the
consummation of the Lakes Redemption. The Lakes Note became convertible on April
22, 2000 and is unsecured. The Company may require conversion of all or a
portion of the principal amount of the Lakes Note after April 22, 2000.
Principal and interest on the Lakes Note, which is five percent (5%) per annum,
is due April 22, 2004. The Note also provides that Lakes has the same status as
a Common Stock shareholder in liquidation in the event of bankruptcy of the
Company.

         The Lakes Warrant has a term of three years and an exercise price of
$1.25 per share, the closing sales price of the Company's Common Stock on the
date of the consummation of the Lakes Redemption. Neither the Lakes Note may be
converted nor the Lakes Warrant exercised if, immediately following such
conversion or exercise, as the case may be, Lakes would beneficially own in
excess of 4.9% of the Company's outstanding Common Stock. The Lakes Note has
"piggyback" registration rights that require the Company to register the shares
issuable upon conversion of the Lakes Note in the event that the Company files
certain types of registration statements with the Securities and Exchange
Commission. Pursuant to similar "piggy-back" registration rights, the shares
issuable upon exercise of the Lakes Warrant were registered on Registration
Statement on Form S-3 (Registration No. 333-84413) filed with the Securities and
Exchange Commission on August 1, 1999, and amended by Amendment No. 1 to Form
S-3 filed on September 23, 1999.

         On June 1, 1999, the Company issued an aggregate of $1,550,000 in
convertible notes to a group of investors including Wayne Mills. Edward G.
Stevenson, the Chairman, Chief Executive Officer and Chief Financial Officer of
the Company, personally guaranteed the repayment of $155,000 of the convertibles
notes. In exchange for such personal guarantee, the Company issued Mr. Stevenson
two 3-year warrants, each to purchase 25,000 shares of the Company's common
stock at $1.25 per share and $1.75 per share, respectively. The shares issuable
upon exercise of the warrants were registered on Registration Statement on Form
S-3 (Registration No. 333-84413) filed with the Securities and Exchange
Commission on August 1, 1999, and amended by Amendment No. 1 to Form S-3 filed
on September 23, 1999.

     In January 2000, a group of investors including Wayne Mills, acquired the
Lakes Note. Mr. Mills beneficially owns $125,000 principal amount of the Lakes
Note.
