ITEM 2. ACQUISITION OF ASSETS
 
  On September 2, 1998, Registrant closed its previously announced and
publicized agreement to acquire all of the outstanding stock of Progressive
Games, Inc., a Delaware corporation ("PGI") from Donald W. Jones for an
aggregate cash consideration of $35,847,000. There was and is no material
relationship between Mr. Jones and Registrant.
 
  The principal assets of PGI are [1] Caribbean Stud(R), a popular proprietary
poker game protected by patents and copyrights, [2] certain other proprietary
games also protected by patents and copyrights (collectively, "Other PGI
Games"), [3] numerous contracts between PGI and the various lessees of
Caribbean Stud(R) and the Other PGI Games, [4] other games in various stages
of development which may or may not find acceptance by regulators and casinos
in the future, and [5] equipment and other physical property used in the
manufacture and distribution of Caribbean Stud(R) and the Other PGI Games.
Caribbean Stud(R) and the Other PGI Games are placed in casinos throughout the
world, almost entirely on leases at fixed monthly rates.
 
  Also on September 2, 1998, Registrant acquired, for an aggregate
consideration of $3,300,000, all of the outstanding stock of P&S Leasing
Corporation, Inc. and all of the legal and beneficial ownership of P&S
Leasing LLC. These two entities held exclusive, non-terminable agreements with
PGI to distribute Caribbean Stud(R) in the states of Mississippi and
Louisiana, respectively. With the acquisition of PGI and these two entities,
Registrant now has exclusive distribution rights [1] to Caribbean Stud(R)
throughout all of the United States except Nevada, [2] to Caribbean Stud(R) in
substantially all other significant legalized gaming jurisdictions throughout
the world and [3] to all of the Other PGI Games in all of the United States
and all other significant legalized gaming jurisdictions throughout the world.
 
  The funds used in these acquisitions represent part of the $86.0 million in
proceeds received by Registrant pursuant to the contemporaneous closing of an
Amended and Restated Credit Agreement dated as of August 28, 1998 among
Registrant as Borrower, certain financial institutions initially signatory
thereto (First Source Financial LLP, The Travelers Insurance Company; Allstate
Insurance Company; Allstate Life Insurance Company; Fidelity & Guaranty Life
Insurance Co.; United States Fidelity & Guaranty Company; Senior Debt
Portfolio, a mutual fund; CIBC Oppenheimer Corp.; Sanwa Business Credit
Corporation; Chancellor/Triton CBO, Limited; and Caravelle Investment Fund,
L.C.C.) together with their permitted assignees as Lenders, and First Source
Financial LLP as Agent.
 
ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS
 
  (a) Set forth below are the Financial Statements of PGI for the years ended
December 31, 1996 and 1997 (audited) and for the three and six months ended
March 31, 1998 and June 30, 1998, respectively (unaudited).

Stockholder
Progressive Games, Inc.
 
  We have audited the accompanying balance sheet of Progressive Games, Inc. as
of December 31, 1997, and the related statements of income and retained
earnings and cash flows for the year then ended. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audit.
 
  We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Progressive Games, Inc. as
of December 31, 1997, and the results of its operations and its cash flows for
the year then ended in conformity with generally accepted accounting
principles.

                            ---------
hereto a complete and accurate list and summary of all policies of insurance of
any nature whatsoever maintained by JONES or PGI pertaining to the business of
PGI, showing, among other things, the amount of coverage, the company issuing
the policy and the expiration date of each policy. To JONES' knowledge, PGI has
adequately insured the PGI Assets that are of insurable character with reputable
insurance companies against loss or damage by fire and other risks to the extent
and in the manner customary for companies engaged in businesses similar to the
Business or owning assets similar to the PGI Assets. During the past three
years, no application by PGI for insurance with respect to the PGI Assets has
been denied for any reason. All such policies are in full force and effect and
will remain in full force and effect until the Closing and PGI has not received
any notice of cancellation with respect thereto. Since February 28, 1998, no
event has occurred which has resulted in material damage to any of the PGI
Assets or which has materially impaired the use of any of the PGI Assets whether
or not such event has been insured against.

                    11.5.4  INVENTORIES. To JONES' knowledge, all inventories
                            -----------
reflected on the February 28, 1998 Balance Sheet are, and all inventories to be
transferred to MIKOHN at the Closing will be, in good and usable condition, and
are saleable by PGI in the ordinary course of business after the Closing. The
values at which such inventories are carried on the December 31, 1997 Balance
Sheet reflect the normal inventory valuation policies of the Business and are in
accordance with generally accepted accounting principles, consistently applied.
The foregoing notwithstanding, prior to the Closing, PGI may transfer to JONES
twenty (20) Gaming Tables, including all electronics and layouts and two (2)
complete sets of spare parts, at no charge to JONES for JONES's use in any legal
casino in which JONES holds a 50% or greater interest; provided, however, JONES
shall not displace any Gaming Tables under license from PGI in operation at such
casino before JONES acquired a 50% interest therein. Unless prohibited by law or
regulatory authority having jurisdiction, PGI shall agree to provide JONES with
spare parts for such tables at a price of PGI's cost plus 15% and access to all
improvements and upgrades.

                    11.5.5  ACCOUNTS AND NOTES RECEIVABLE. Schedule 11.5.5
                            -----------------------------
hereto contains a complete and accurate list of all material accounts and notes
receivable of PGI as of the date of February 28, 1998 and an aging schedule of
such accounts and notes receivable. Such accounts and notes receivable arose in
bona-fide arms length transactions in the ordinary course of business of PGI.

                    11.5.6  PERMITS. Except as set forth in the Schedules, PGI
                            -------
has all material permits and licenses which are necessary for the conduct of the
Business as now conducted and at the Closing PGI will have all such permits and
licenses except gaming licenses the loss of which will not have a PGI Material
Adverse Effect. There is set forth in Schedule 11.5.6 hereto a complete and
accurate list of each material permit, license and certificate or authorization
issued to PGI by any third party.

                    11.5.7  TAXES. To JONES knowledge, PGI has filed all
                            -----
necessary federal, state, local and foreign income, property and franchise tax
returns and paid all taxes shown as due thereon; all tax liabilities are
adequately provided for on the books of PGI and JONES has no knowledge of any
tax deficiency of PGI or any tax proceeding or action pending or threatened
against PGI which would have a PGI Material Adverse Effect. To JONES' knowledge,
all federal, state, local and foreign income, property and franchise tax returns
filed by or on behalf of PGI are complete and accurate in all material respects
in accordance with all legal requirements applicable thereto. PGI is not a party
to or bound by any tax indemnity, tax sharing or tax allocation agreement. JONES
shall indemnify MIKOHN and PGI against any tax liabilities imposed on PGI as a
result of any non-payment or underpayment of taxes owed with respect to periods
prior to the Closing. PGI and MIKOHN shall promptly remit to JONES any tax
refunds received after the Closing as a result of any over payment of taxes of
PGI paid with respect to periods prior to the Closing. MIKOHN will promptly
provide JONES with copies of all correspondence or other information from taxing
authorities with respect to any assessment or proposed assessment of, or any
inquiry or examination by such taxing authorities in connection with, taxes of
PGI covered by the foregoing indemnity. JONES shall have the right to take any
actions he deems necessary and appropriate in connection with the matters
covered by the foregoing indemnity, including contesting, defending and settling
any assessment of taxes or proposed assessment of taxes. MIKOHN will give JONES
a power of attorney to act on PGI's behalf in handling all matters covered by
the foregoing indemnity and shall provide JONES with access to all books and
records reasonably requested by JONES in connection with the foregoing
indemnity. In no event will JONES be liable for any tax incurred by PGI as a

                                       16
<PAGE>
 
result of an election made by MIKOHN for PGI under Section 338 of the Internal
Revenue Code of 1986, as amended, and MIKOHN agrees to defend, indemnify and
hold harmless JONES from and against any such tax.

               11.6 CONTRACTS. Except as set forth in the Schedules, PGI has not
                    ---------
received notice of any default or claim of default under any provision of any
material contract to which PGI is a party and, to JONES' knowledge, no event has
occurred which, with the passage of time or the giving of notice (or both),
would constitute a default by PGI (or, to JONES' knowledge, any other party
thereto) under any provision thereof, or would permit modification, acceleration
or termination of any contract by any other party thereto or by PGI. There is
set forth in Schedule 11.6 hereto a complete and accurate list of all Gaming
Table leases and Gaming Table license agreements and all other material
contracts, whether written or oral, between PGI and any party who is obligated
to make payments or provide services to PGI or to whom PGI is obligated to make
payments or provide service in an amount exceeding $10,000 per year.

               11.7 LITIGATION; COMPLIANCE WITH LAW. Except as set forth in
                    -------------------------------
Schedule 11.7 and except for gaming investigations conducted in the ordinary
course of the Business, no material investigation or review by any governmental
entity with respect to PGI is pending or, to JONES' knowledge, threatened, nor
has any governmental entity indicated to PGI an intention to conduct the same;
and there is no action, suit or proceeding pending or, to JONES' knowledge,
threatened against or affecting PGI at law or in equity, or before any federal,
state, municipal or other governmental department, commission, board, bureau,
agency or instrumentality, which either singly or in the aggregate would, if
adversely determined, have a PGI Material Adverse Effect, or which would impair
JONES' and PGI's ability to perform this Agreement. Except as set forth in
Schedule 11.7, to JONES' knowledge, the Business is not being conducted in
violation of any applicable law, ordinance, regulation, decree or order of any
court or governmental entity which could have a PGI Material Adverse Effect and
JONES has no knowledge of any pending or proposed laws, ordinances or
regulations which, if enacted or adopted, could have a PGI Material Adverse
Effect (other than matters of public knowledge or which are generally applicable
to the industries in which the Business is conducted).

               11.8 LABOR RELATIONS; EMPLOYEES. Except as set forth in the
                    --------------------------
Schedule 11.8, as of the date hereof and the Closing, PGI has paid or made
provision for the payment of all salaries and wages (including without
limitation, bonuses, sick and vacation pay, commissions to salesmen, etc.)
accrued through the date hereof to or for the benefit of employees of the
Business and has

                                       17
<PAGE>
 
complied in all material respects with all applicable laws, rules and
regulations relating to the employment of labor, including those relating to
wages, hours, collective bargaining and the payment and withholding of taxes,
and has withheld and paid to the appropriate governmental authority, or is
holding for payment not yet due to such authority, all amounts required by law
or agreement to be withheld from the wages or salaries of such employees. Since
February 28, 1998, there has been no material adverse change in the relationship
of PGI with its respective employees (including any threatened union
organization or renegotiation of any union contract) nor any strike or labor
disturbance by any such employees or any other employees of PGI performing
services in connection with the Business, and JONES is not aware of any
indication that such a change, strike or labor disturbance is likely.

               11.9 EMPLOYEE BENEFIT PLANS. PGI does not have any pension,
                    ----------------------
profit sharing, savings, bonus, incentive, insurance, welfare, stock option,
severance or vacation or other employee benefit plans, whether written or oral
(including, without limitation, any such plans within the meaning of Section
3(3) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")) in which any employees of the Business participate ("Benefit Plans"),
except as disclosed in Schedule 11.9. With respect to each Benefit Plan, PGI has
delivered to MIKOHN complete and correct copies of (a) the Benefit Plan (or a
written summary of any unwritten Benefit Plan); (b) any related trust agreement,
insurance contract or other funding vehicle; (c) the last three annual reports
on IRS Form 5500; (d) the latest actuarial valuation report; and (e) any summary
plan description or employee handbook. Those Benefit Plans within the meaning of
Sections 3(2) and 3(37)(A) of ERISA are hereinafter referred to as "Multi-
employer Qualified Plans" or "Multi-employer Plans", and all other Benefit Plans
within the meaning of Section 3(2) of ERISA are hereinafter referred to as
"Single Employer Qualified Plans" or "SEQ Plans."

                    11.9.1  With Respect to the SEQ Plans:

                            11.9.1.1  Each SEQ Plan and related trust has
received a favorable determination letter from the Internal Revenue Service with
respect to its qualified status under Sections 401(a) and 501(a) of ERISA and,
to the knowledge of PGI, nothing has occurred since the date of such letter
which would adversely affect its validity.

                            11.9.1.2  All data submitted by PGI to the actuary
for use in the actuarial valuations for all plan years of each SEQ Plan prepared
as of the date hereof was accurate and complete in all material respects, and
each such valuation fairly

                                       18
<PAGE>
 
presents the actuarial position of the respective plan covered thereby as of
such date in accordance with generally accepted actuarial principles.

                            11.9.1.3  Since the effective date of ERISA, no SEQ
Plan or related trust has incurred an "accumulated funding deficiency" (whether
or not waived) as such term is defined in ERISA or in the Code.

                    11.9.2  With respect to the Multi-employer Plans:

                            11.9.2.1  PGI has not received notice, or has any
reason to believe, that any other Multi-employer Plan has not received such a
favorable determination letter or any other development since such date which
would cause the loss of such qualified status.

                            11.9.2.2  All data submitted by PGI to any sponsor
of a Multi-employer Plan with respect to the Multi-employer Plans fairly present
the employee data requested by such sponsors.

                            11.9.2.3  With respect to each Multi-employer Plan,
PGI has previously disclosed in writing (i) PGI's contribution rate and number
of contribution base units for each of the last three years; and (ii) the
liability which PGI would incur on a "complete withdrawal", within the meaning
of Section 4203 of ERISA, as of the Closing Date without regard to any
limitation, reduction or adjustment of liability under Title IV of ERISA or the
provisions of the plan. With respect to any Benefit Plan or any plan which is
contributed to by any entity treated as a single employer with PGI under Section
414(b), (c), (m) or (o) of the code ("ERISA Affiliate") and which is a multi-
employer plan within the meaning of Section 3(37) of ERISA; (iii) neither PGI
nor any ERISA Affiliate has incurred any withdrawal liability under Section 4201
et seq. of ERISA which had not been satisfied or received notice of any claim or
- -- ---
demand for withdrawal liability; (iv) PGI and its ERISA Affiliates have timely
made contributions required by the terms of the plan or any collective
bargaining agreement; and (v) to the knowledge of PGI and its ERISA Affiliates,
no such plan is in reorganization, within the meaning of Section 4241 of ERISA,
or is or may become insolvent, within the meaning of Section 4245 of ERISA, and
no such plan is a party to any pending merger or transfer of assets and
liabilities. Neither PGI nor any ERISA Affiliate has incurred any withdrawal
liability under Section 4063 or 4064 of ERISA.

                            11.9.2.4  PGI has not received notice that any
collective bargaining agent with respect to, or sponsor of, a Multi-employer
Plan has terminated, caused the termination 

                                       19
<PAGE>
 
of, or intends to terminate, coverage under any Multi-employer Plan of employees
of any facility or business to be acquired by MIKOHN hereunder, or the coverage
of any other participants therein so as to constitute a termination of any 
Multi-employer Plan.

                    11.9.3  Each Benefit Plan and each funding medium which may
be attendant thereto, including group annuity contracts, have been in all
material respects operated and administered in accordance with their provisions
and applicable law. On or prior to the date hereof PGI has contributed to each
SEQ Plan not less than the amounts accrued for such Plan for all plan years
prior to the current plan year and on or prior to the Closing will have
contributed to such plan not less than the amounts required for such plan for
the current fiscal year of the plan prorated for the elapsed portion of such
fiscal year to the Closing. As to any other Benefit Plan or union contract to be
assumed by MIKOHN, PGI has made or will have made prior to the Closing all other
contributions or payments required to be paid or accrued with respect to such
Plan. Other than routine claims for benefits under the Benefit Plans in the
ordinary course of business, there are no actions, suits or claims pending or,
to the knowledge of PGI, threatened against any Benefit Plan or any of its
assets, and PGI has no knowledge of any facts which could give rise to any such
actions, suits or claims. No Benefit Plan is currently under investigation or
audit by a governmental agency and, to PGI's knowledge, no such investigation or
audit is contemplated or under consideration.

                    11.9.4  PGI has paid all required premium payments to the
Pension Benefit Guaranty Corporation ("PBGC") with respect to the Benefit Plans
and has not incurred any other liability to the PBGC with respect to any plan
currently or formerly contributed to or maintained by PGI or any ERISA
Affiliate. PGI has timely paid all contributions to any SEQ Plan subject to
Title IV of ERISA. No proceedings have been undertaken by PGI or the PBGC to
terminate any SEQ Plan subject to Title IV of ERISA and there has been no
"reportable event" within the meaning of Section 4043 of ERISA with respect to
any such plan (for which the 30-day notice requirement has not been waived)
within the last 6 years.

                    11.9.5  Neither PGI nor any of its subsidiaries, nor any of
its affiliates, directors, officers or employees has, with respect to the
Benefit Plans, engaged in any "prohibited transaction," as such term is defined
in the Code or ERISA, nor have any such Plans, the related trusts or any
trustee, administrator or other "party-in-interest" (as defined in ERISA)
engaged in any such prohibited transaction, which could subject PGI or MIKOHN,
or any of their directors, officers or employees to any sanctions, taxes or
penalties on or with respect to prohibited 

                                       20
<PAGE>
 
transactions which may be imposed under the Code, ERISA or any other applicable
law.

                    11.9.6  To JONES' knowledge, neither PGI nor any of its
subsidiaries, nor any of its or their directors, officers or employees, nor to
PGI's knowledge, any other "fiduciary" (as defined in ERISA), has, with respect
to any Benefit Plan, committed any breach of fiduciary responsibility imposed by
ERISA or any other applicable law which could subject PGI or MIKOHN or any of
their directors, officers, employees or persons to liability under ERISA or any
other applicable law.

                    11.9.7  Each Benefit Plan covers only present or former
employees of PGI. No Benefit Plan provides life or health benefits to former
employees of PGI, other than continuation coverage required by Section 4980B of
the Code and provided at the expense of the former employee.

                    11.9.8  PGI has no plan or commitment, whether legally
binding or not, to create any additional Benefit Plan or to modify any existing
Benefit Plan except with respect to changes required by applicable law or as
expressly provided for in this Agreement. Neither the execution and delivery of
this Agreement nor the consummation of the transactions contemplated hereby will
(i) result in any payment becoming due to any current or former employee of PGI,
(ii) increase any benefits otherwise payable under any Benefit Plan, or (iii)
result in the acceleration of the time of payment or vesting of any such
benefits.

              11.10 INTELLECTUAL PROPERTY. Except as set forth in Schedule
                    ---------------------
11.10, to JONES' knowledge, the Business as now conducted by PGI does not
infringe any patent, trademark, trade name, trade secret or copyright held by
others or any license, authorization or permit held by PGI, in any manner which
may have a PGI Material Adverse Effect.

                    11.10.1  Schedule 11.10.1 hereto lists all patents, patent
applications, inventions, trade names, trademarks, service marks, brand names,
copyrights and registrations and applications therefor, owned by or used in the
Business as now conducted by PGI (the "Intellectual Property"). To JONES'
knowledge, PGI owns the Intellectual Property, the authorship add inventorship
identified in Schedule 11.10.1 is accurate and the Intellectual Property (except
for patent claims currently under rejection in re-examination proceedings) is
not invalid and is enforceable.

                    11.10.2  Neither JONES nor PGI has granted any licenses or
other rights and has no obligations to grant

                                       21
<PAGE>
 
licenses or other rights to any Intellectual Property other than the licenses
and rights disclosed on Schedule 11.10.2 hereto.

                    11.10.3  Neither JONES nor PGI has made any claim of any
violation or infringement by others of its rights to or in connection with the
Intellectual Property or technology used or held for use in the Business, and
neither JONES nor PGI know of any basis for making any such claim except those
claims disclosed on Schedule 11.10.3.

                    11.10.4  There are no interferences or other contested
proceedings or reexamination proceedings, either pending or, to the knowledge of
JONES or PGI, threatened, in the United States Copyright Office, the United
States Patent and Trademark Office or any federal, state or local court or
before any other governmental agency or tribunal, relating to any pending
application with respect to the Intellectual Property except those proceedings
disclosed in Schedule 11.10.4.

              11.11 YEAR 2000 ISSUE. JONES and PGI acknowledge that the approach
                    ---------------
of the year 2000 has become a potential problem for businesses utilizing
computers in their operations since many computer programs are date sensitive
and will only recognize the last two digits of the year, thereby recognizing the
year 2000 as the year 1900 or not at all (the "Year 2000 Issue"). To JONES'
knowledge, except as disclosed in Schedule 11.11, all software programs
developed by PGI and included in the PGI Assets are Year 2000 compliant, that
is, the operation and functionality of such software programs will not be
materially adversely affected by the Year 2000 Issue.

              11.12 CUSTOMERS AND SUPPLIERS. Except as disclosed in the
                    -----------------------
Schedules, neither JONES nor PGI has received any notice of, and JONES knows of
no reasonable basis for, any matter involving PGI's arrangements with PGI's
customers and suppliers of the Business that would have a PGI Material Adverse
Effect.

              11.13 DISCLOSURE OF ALL MATERIAL FACTS. No representation or
                    --------------------------------
warranty by JONES in this Agreement (including all Exhibits and Schedules
attached hereto) or in any certificate furnished to MIKOHN in connection with
the Closing of the transactions contemplated hereby contains, or will at Closing
contain, any untrue statement of a material fact or omits to state a material
fact necessary to make the statements contained herein or therein, in light of
the circumstances under which they were made, not misleading.

              11.14 CAPITALIZATION. The authorized capital stock of PGI consists
                    --------------
of 3,000 shares, $.01 par value, of which 2,700 shares are issued and
outstanding. All of the PGI Shares are 

                                       22
<PAGE>
 
owned, beneficially and of record, only by JONES and, at the time they are
delivered to MIKOHN at the Closing, will be free from any charge, lien,
encumbrance or adverse claim of any kind whatsoever. At the Closing, JONES will
have the absolute unrestricted right, power, authority and capacity to transfer
the PGI Shares to MIKOHN and upon the Closing, without exception, MIKOHN will
acquire from JONES legal and beneficial ownership of, good and valid title to,
and all rights to vote, the PGI Shares, free from any charge, lien, encumbrance
or adverse claim of any kind whatsoever. All of the PGI Shares have been duly
authorized and validly issued and are fully paid and nonassessable. There are no
options, warrants, conversion rights, rights of exchange, or other rights,
plans, agreements or commitments of any nature whatsoever (including, without
limitation, conversion or preemptive rights) providing for the purchase,
issuance or sale of any shares of PGI's capital stock or any securities
convertible into or exchangeable for any shares of PGI's capital stock.

              11.15 SUBSIDIARIES AND AFFILIATES. Except for the PGI Affiliates
                    ---------------------------
or as disclosed in the Schedules, PGI does not presently own, directly or
indirectly, any interest in any other corporation, association, joint venture or
other business entity. At the Closing, PGI will own all of the issued and
outstanding capital stock of the PGI Affiliates ("Affiliate Shares"), except as
may be provided in Section 6.14, which will then be subsidiaries of PGI. At the
Closing, except as may be provided in Section 6.14, the Affiliate Shares will be
owned, beneficially and of record, by PGI and, will be free from any charge,
lien, encumbrance or adverse claim of any kind whatsoever. As of the Closing,
PGI will have legal and beneficial ownership of, good and valid title to, and
all rights to vote, the Affiliate Shares, free from any charge, lien,
encumbrance or adverse claim of any kind whatsoever. All of the Affiliate Shares
have been duly authorized and validly issued and are fully paid and
nonassessable. There are no options, warrants, conversion rights, rights of
exchange, or other rights, plans, agreements or commitments of any nature
whatsoever (including, without limitation, conversion or preemptive rights)
providing for the purchase, issuance or sale of any Affiliate Shares or any
securities convertible into or exchangeable for any shares of Affiliate Shares.

              11.16 PROPERTIES. PGI does not own or hold title to any real
                    ----------
property. With respect to the property and assets it leases, PGI is in
compliance in all material respects with such leases and holds a valid leasehold
interest free of any material liens, claims or encumbrances of any kind
whatsoever except as disclosed in the Schedules. There is set forth in Schedules
11.16[1] and 11.16[2] hereto: [1] a list of all leases or rental contracts under
which PGI is a lessee, lessor, sublessee or sublessor and [2] a list of all
equipment used by PGI in the

                                       23
<PAGE>
 
operation of its business which is owned or leased by PGI and which had an
original cost of $15,000 or more.

              11.17 INDEBTEDNESS. Schedule 11.17 hereto contains a complete list
                    ------------
of each and every agreement or other instrument under or pursuant to which PGI
has outstanding indebtedness for borrowed money. JONES has furnished MIKOHN with
true and correct copies of each such agreement and instrument, including all
amendments with respect thereto through the date of this Agreement, PGI (and
JONES to the extent responsible for the payment of the obligations thereunder)
is not in default in any material respect under any such agreement or instrument
and, to JONES' knowledge, no other party to any such agreement or instrument is
in default in any material respect under any such agreement or instrument.

              11.18 DIRECTORS, OFFICERS AND EMPLOYEES. Schedule 11.18 hereto
                    ---------------------------------

attorneys at law who are authorized to prosecute intellectual property matters
or litigation, on behalf of PGI, and [2] the names and addresses of all banks or
other financial institutions in which PGI has an account, deposit or safe-
deposit box, with the number and a description of the account and the names of
all persons authorized to draw on such account or deposit or to have access to
such boxes.

              11.20 GOOD AND MARKETABLE TITLE TO SHARES. JONES has, and will
                    -----------------------------------

authority to execute, deliver and perform this Agreement, and the other
instruments and documents required or contemplated herein. Such execution,
delivery and performance have been duly authorized by all necessary action on
the part of MIKOHN, do not and will not require the approval of the shareholders
of MIKOHN and do not and will not contravene the Certificate of Incorporation or
By-Laws of MIKOHN or conflict with, result in a breach of, or entitle any party
(with due notice or lapse of time or both) to terminate, accelerate or call a
default with respect to, or result in the creation or imposition of any lien,
charge, encumbrance or claim of any nature whatsoever upon any of the PGI Assets
pursuant to, any agreement or instrument to which MIKOHN is a party or by which
MIKOHN is bound. The execution, delivery and performance of this Agreement by
MIKOHN will not result in any violation by MIKOHN of any law, rule or regulation
applicable to MIKOHN. MIKOHN is not a party to, or subject to or bound by, any

satisfy the conditions set forth in Section 6.13 or Section 7 of this Agreement
or otherwise to consummate the transactions contemplated by this Agreement, and
MIKOHN has no knowledge of any present condition or contingency (other than
matters of public knowledge or which are generally applicable to the industries
in which MIKOHN conducts its business) which MIKOHN reasonably expects would
have such effect.

               12.6  SURVIVAL. The representations and warranties of MIKOHN
                     --------
herein shall survive the Closing for a period of one (1) year.

JONES and PGI shall not, nor shall they permit any affiliate of JONES or PGI, or

investment banker, broker, attorney or accountant retained by it) to initiate,
solicit or facilitate, directly or indirectly any inquiries or the making of any
proposal with respect to the sale, lease or other disposition of the stock or
assets of PGI ("Other Transaction"), engage in any discussions or negotiations
concerning, or provide to any person or entity any information or data relating
to PGI, for the purpose of, or otherwise cooperate in any way with or assist or
participate in, or facilitate any inquiries or the making of any proposal which
constitutes, or may reasonably be expected to lead to, a proposal to seek or
effect any Other Transaction, or agree to or endorse any Other Transaction. PGI
shall promptly advise MIKOHN of, and communicate the material terms of, any
proposal it may receive, or any inquiries it receives which may reasonably be
expected to lead to such a proposal relating to an Other Transaction and the
identity of the person or entity making it. PGI shall further advise MIKOHN of
the status and changes in the material terms of any such proposal or inquiry (or
amendment to any of them). During the term of this Agreement, PGI shall not
enter into any agreement,

                                       27
<PAGE>
 
oral or written, and whether or not legally binding, with any person or entity

the foregoing sentence.

               ----------

               ---------
instances, upon performance of any of the provisions of this Agreement or to
take advantage of any of its rights hereunder shall not operate as a waiver
thereof or preclude any other or further exercise thereof or the exercise of any
other right or power.

          19   FLORIDA LAW. This Agreement shall be governed by, and interpreted
               -----------

entitled to have and recover from the losing party reasonable attorneys' fees

          22   CONDUCT OF BUSINESS PENDING CLOSING. Prior to the Closing,
               -----------------------------------
without the prior written consent of MIKOHN which shall not be unreasonably
withheld or delayed, JONES covenants that, except in connection with matters
disclosed in this Agreement or the Schedules hereto or as otherwise permitted

provided that PGI shall be entitled to pay cash dividends to JONES.

               22.5  Except as otherwise requested by MIKOHN and without making
any commitment on its behalf, PGI shall use its best efforts to preserve the PGI
Assets and maintain them in substantially the same condition as of the date of
this Agreement, reasonable wear and tear excepted; provided, however, that the
foregoing exception shall not relieve PGI from the obligation to make repairs
and otherwise maintain the PGI Assets in accordance with good management
practice. PGI shall also keep its business organizations at the Business
substantially intact, shall use its best efforts to keep available to MIKOHN the
services of present employees at the Business and shall use its best efforts to
preserve the good will of suppliers, customers and others having business
relations with PGI.

               22.6  No new bonus or pension plan or other similar contract or
commitment or any wage or salary increases in excess of $20,000 in the aggregate
or any collective bargaining agreement which relates to the Business shall be

                                       29
<PAGE>
 
               22.7  PGI and JONES will not take any action or fail to take any
action as may be required under any applicable law for the valid and effective
consummation of the transactions provided for in this Agreement; provided,
however, that the foregoing shall not require PGI or JONES to agree to

alter, suspend or otherwise modify the terms of this Agreement.

               22.8  No change will be made affecting the banking and safe
deposit box arrangements of the Business.

               22.9  No indebtedness shall be incurred with respect to the PGI

event shall any indebtedness in excess of $50,000 in the aggregate be incurred.

               22.10 The Business shall remain open and shall be conducted in
the same manner as it is currently conducted.

               22.11 PGI shall not issue, redeem or purchase any of PGI's

any options, warrants or rights to subscribe for its capital stock or securities
convertible into its capital stock or commit to do any of the foregoing.

               22.12 PGI shall not enter into any employment contract or
agreement with any existing or prospective employee which is not terminable at
will.

               22.13 Except in the ordinary course of Business, PGI shall not
pay any obligations or liability, fixed or contingent, other than current

               22.17 Neither JONES nor PGI will take any action, or omit to take
any action, within their control, that would cause, and shall promptly notify
MIKOHN in writing of any event or occurrence which causes, any of the
representations and warranties set forth in Section 11 hereof to become untrue,
incomplete or

                                       30
<PAGE>
 
inaccurate in any material respect as of or prior to the Closing Date.

          23   COMPLETE AGREEMENT. This Agreement contains the complete
               ------------------
agreement of the parties, and supersedes any and all prior contemporaneous

               --------- 

               25.1  INDEMNITY BY JONES. From and after Closing, JONES covenants
                     ------------------
and agrees to indemnify and hold MIKOHN and its affiliates (which shall include
PGI; each a "Purchaser Indemnitee") harmless in respect of any Damages imposed
upon or sustained by a Purchaser Indemnitee by reason of:

                     25.1.1  any misrepresentation, breach of warranty or
nonfulfillment of any agreement on the part of JONES under this Agreement, or in
any certificate or other instruments described and referred to in this
Agreement, or in the Exhibits and Schedules attached hereto, or to be furnished
to MIKOHN hereunder, unless the Purchaser Indemnitee knew or had reason to know
of any such misrepresentation, breach or nonfulfillment prior to Closing;

                     25.1.2  any claim or cause of action brought against PGI by
any former employee of PGI relating to or arising from the employment
relationship or termination thereof prior to the Closing unless the Purchaser
Indemnitee knew or had reason to know of any such claim or cause of action;

                     25.1.3  any claim or cause of action brought by Par-4, Inc.
or Anthony Tomasello relating to that certain License Agreement dated September
21, 1993 by and between PGI and MIKOHN; and

                     25.1.4  any claim or cause of action brought by August
Masciotra or Gary Amundsen arising from their employment relationship with PGI
or termination thereof.

                     25.1.5  For purposes of this Agreement, 

                                       31
<PAGE>
 
"Damages" means all damages, assessments, taxes, judgments, costs and expenses
incident to any of the foregoing, including, but not limited to, attorneys'
fees.

          26   INDEMNITY BY MIKOHN. From and after Closing, MIKOHN agrees to
               -------------------
indemnify JONES and his heirs, successors, personal representatives, devisees
and assigns (each a "Stockholder Indemnitee") and hold them harmless in respect
of any Damages imposed upon or sustained by a Stockholder Indemnitee by reason
of any misrepresentation, breach of warranty or nonfulfillment of any agreement
on the part of MIKOHN under this Agreement, or in any certificate or other
instruments described and referred to in this Agreement to be furnished to JONES
hereunder, unless the Stockholder Indemnitee knew or had reason to know of any
such misrepresentation, breach or nonfulfillment at the time of Closing.

          27   PROCEDURES FOR THIRD-PARTY CLAIMS.
               --------------------------------- 

               27.1  If a Purchaser Indemnitee or a Stockholder Indemnitee (an
"Indemnitee") receives written notice of the assertion of any claim or of the
commencement of any action or proceeding by any entity who is not a party to
this Agreement (a "Third Party Claim") against or affecting such Indemnitee, and
if such assertion were presumed to be true (regardless of the actual outcome)
and a party (the "Indemnifying Party") could be obligated to provide
indemnification under this Agreement as a result of or in connection with such
claim, action or proceeding, such Indemnitee will give such Indemnifying Party
reasonably prompt written notice thereof, but in any event no later than thirty
(30) calendar days after receipt of such written notice of such Third Party
Claim; provided however, that failure to give notice as provided in this Section
27.1 shall not relieve the Indemnifying Party of its indemnification obligations
under Section 25 or Section 26 except to the extent that such Indemnifying Party
is actually prejudiced by such failure. Said written notice to the Indemnifying
Party shall set forth the basis of the Third Party Claim in reasonable detail
and include copies of all pertinent correspondence relating to such Third Party
Claim. The Indemnifying Party will have the right to assume and control the
defense of any Third Party Claim at such Indemnifying Party's sole expense and
by such Indemnifying Party's own counsel (which counsel must be reasonably
satisfactory to the Indemnitee), by giving written notice to the Indemnitee (the
"Notice of Defense") no later than thirty (30) calendar days after receipt of
the above-described notice of such Third Party Claim. The Indemnitee also will
have the right to participate in the defense of any Third Party Claim assisted
by counsel of its own choosing, but all fees and expenses of such counsel shall
be paid by the Indemnitee. The Indemnifying Party and the Indemnitee will
cooperate with 

                                       32
<PAGE>
 
each other in good faith in such defense and make available all employees and
books and records in its control as reasonably deemed necessary with respect to
such defense (but not to the extent that would require waiver of any privilege).
If the Indemnitee does not receive from the Indemnifying Party a Notice of
Defense with respect to a Third Party Claim within the thirty (30) day period
described above, the Indemnitee may, at its option, elect to solely defend the
Third Party Claim assisted by counsel of its own choosing, and the Indemnifying
Party will be liable for all reasonable costs and expenses, and all settlement
amounts (subject to and in accordance with Section 27.3) or other liabilities,
losses, damages and injuries paid or incurred in connection therewith to the
extent such claim is or would have been indemnifiable under this Agreement if
such claim is or had been proved.

               27.2  If, within the thirty (30) day period set forth in Section
27.2, an Indemnitee receives a Notice of Defense from an Indemnifying Party with
respect to any Third Party Claim, the Indemnifying Party will not be liable for
any legal expenses of the Indemnitee incurred after receipt by the Indemnitee of
such Notice of Defense.

               27.3  In the event there is a dispute between the Indemnifying
Party and Indemnitee concerning whether a Third Party Claim should be contested,
settled or compromised, it shall be settled, compromised or contested in
accordance with the next succeeding sentences; provided, however, that the
                                               --------  -------
Indemnitee, or its respective successors or assigns, shall neither be required
to refrain from paying or satisfying any claim which has matured by court
judgment or decree, unless appeal is taken thereafter and proper appeal bond
posted by the Indemnifying Party, nor shall the Indemnitee be required to
refrain from paying or satisfying any Third Party Claim after and to the extend
that such Third Party Claim has resulted in an unstayed injunction. The
Indemnifying Party shall not, without the Indemnitee's prior written consent
which is not to be unreasonably withheld, settle or compromise any action or
claim or consent to the entry of any judgment with respect to any action, claim
or proceeding for anything other than money damages paid by the Indemnifying
Party unless the settlement does not involve the imposition of any liability or
obligation on the Indemnitee or any restriction on its activities. The
Indemnifying Party may, without the Indemnitee's written consent, settle or
compromise any such action or claim or consent to entry of any judgment with
respect to any such action or claim which requires solely the payment of money
damages by the Indemnifying Party. Subject to the foregoing, in the event that
the Indemnifying Party, on the one hand, or the Indemnitee, on the other hand,
has reached a good faith, bona fide settlement, agreement or compromise, subject
to approval hereunder, with any claimant regarding a matter which may be the
subject of

                                       33
<PAGE>
 
indemnification hereunder, and desires to settle on the basis of such agreement
or compromise, such party who desires to so settle or compromise shall notify
the other party in writing of its desire setting forth the terms of such
settlement or compromise (the "Notice of Settlement"). The Third Party Claim may
be settled or compromised on such basis unless within twenty (20) days of the
receipt of the Notice of Settlement the party who issued the Notice of
Settlement receives a notice from the other party of its desire to continue to
contest the matter (the "Notice to Contest") and, in such case:

               27.3.1 Should the Indemnitee deliver a Notice to Contest, the
claim shall be so contested and the liability of the Indemnifying Party shall be
limited as provided in Clause 27.3.3 below:

               27.3.2 If the settlement or compromise could result in a further
claim for indemnification being made against the Indemnifying Party and if the
Indemnifying Party delivers the Notice to Contest, the claim shall be so
contested and the liability of the Indemnitee shall be limited as provided in
clause 27.3.3 below ; and

               27.3.3 If a matter is contested as provided in Sections 27.3.1 or
27.3.2 above and is later adjudicated, settled, compromised or otherwise
disposed of and such adjudication, compromise, settlement or disposition results
in a liability, loss, damage or injury in excess of the amount for which one
party desired previously to settle the matter, then the liability of such party
shall be limited to such lesser proposed settlement amount (plus attorney's fees
and expenses to the date of the proposed but unapproved settlement to the extent
provided for in Section 27.3 above) and the party contesting the matter shall be
solely responsible for any additional amount.

          28 LIMITATIONS OF INDEMNIFICATION OBLIGATIONS. The Purchaser
             ------------------------------------------
Indemnitee shall not have any right to indemnification under this Agreement
until the aggregate of all Damages Claimed by all Purchaser Indemnitees exceeds
$250,000, and in such event the indemnification obligations of the Stockholder
Indemnitee hereunder shall apply to all Damages in excess of such amount until
such Damages aggregate $2,500,000, from which point the Stockholder Indemnitee
shall have no obligation to indemnify the Purchaser Indemnitees against further
Damages.

          29 LOSSES NET OF INSURANCE, ETC. The amount of any Damages suffered as
             ----------------------------
a result of an injury to an Indemnitee for which indemnification is available
hereunder, shall be net of any insurance proceeds, if any, actually received by
the Indemnitee in respect of such injury and (i) increased to take account of
any

                                       34
<PAGE>
 
net tax cost incurred by the Indemnitee arising from the receipt of indemnity
payments hereunder (grossed up for such increase an any tax consequences
resulting from any payments pursuant to this Section 29 and (ii) reduced to take
account of any net tax benefit realized by the Indemnitee arising from the
incurrence or payment of any such Damages. In computing the amount of any such
tax cost or tax benefit, the Indemnitee shall be deemed to recognize all other
items of income, gain, loss, deduction or credit before recognizing any item
arising from the receipt of any indemnity payment hereunder or the incurrence or
payment of any indemnified Damages. Any indemnity payment under this Agreement
shall be treated as an adjustment to the Purchase Price for tax purposes, unless
a final determination (which shall include the execution of a Form 870-AD or
successor form) with respect to the Indemnitee causes any such payment not to be
treated as an adjustment to the Purchase Price for Federal tax purposes. The
purpose of this Section 29 is to put the Indemnitee in such a position as if the
event for which indemnification is provided hereunder and Damages awarded had
not occurred.

otherwise. The parties will stipulate to such orders as may be necessary to
effect the intent of this standstill provision. Each party shall agree to extend

proceedings are stayed by a period equal to the length of time this Agreement is
in effect and has not been terminated.

                     32.2 Notwithstanding the foregoing, this standstill
provision shall not apply to any claims or causes of action arising from
activities subsequent to the date this Agreement is signed by all parties and
shall not apply to activities reasonably necessary to avoid dismissal for
failure to prosecute or similar events that might jeopardize a party's claims or
defenses.

                     32.3 So long as this Agreement is in effect and has not

release, waiver, compromise or other resolution of any such rights or claims;
all such rights and claims are expressly reserved and shall be wholly unaffected

prior to the Closing or [2] expires by its terms.

                 33  TERMINATION.
                     ----------- 

                     33.1 TERMINATION BY MUTUAL CONSENT. At any time prior to
                          -----------------------------
the Closing, this Agreement may be terminated by written consent of MIKOHN and
JONES.

               33.2  TERMINATION BY JONES.
                     --------------------

                     33.2.1 If the Closing has not occurred by the latest date
provided in Section 4 because the condition contained in Section 6.12 or Section
6.13 is or has not been satisfied, JONES may terminate this Agreement at any
time by delivery of written notice to MIKOHN and the Earnest Money Deposit,
together with interest thereon, shall be paid to MIKOHN.

                     33.2.2 If JONES is not provided the CIBC Highly Confident
Letter on or before April 30, 1998, JONES may terminate this Agreement at any
time by delivery of written notice to MIKOHN and the Earnest Money Deposit,
together with interest thereon, shall be paid to JONES.

<PAGE>
 
6.13 cannot be obtained by MIKOHN because of a material adverse change in the
financial condition or results of operations of MIKOHN, JONES may terminate this
Agreement and the Earnest Money Deposit together with interest thereon shall be
paid to JONES.

                         33.2.4 If it appears reasonably probable that a consent
required by JONES under Section 4.4.7 or by MIKOHN under Section 4.5.3 cannot be
obtained by the Closing Date, and provided further that the inability to obtain
such consent is the result of a claim or assertion by a regulatory agency that
MIKOHN is not a suitable party to own or hold the PGI Shares or otherwise due to
a fact or circumstance within the control of MIKOHN, MIKOHN shall give JONES
prompt notice of such fact. JONES shall have the right to terminate this
Agreement after providing MIKOHN with written notice and a thirty (30) day
notice to cure. If this event is not cured within said thirty (30) day period,
the Earnest Money Deposit, together with interest thereon, shall be paid to
JONES.

                         33.2.5 If MIKOHN breaches this Agreement and such
breach is not cured by MIKOHN within thirty (30) days of notice from JONES,
JONES may terminate this Agreement and the Earnest Money Deposit, together with
interest thereon, shall be paid to JONES.

provided above, this Agreement shall become of no further force or effect and
all parties hereto shall bear their own costs associated with this Agreement and

not relieve any person or entity of liability for breach of or interference with

                         ----------------------

not occurred by September 30, 1998.

               34   EACH PARTY TO BEAR OWN COSTS. Each of the parties shall
                    ----------------------------

     Re:  First Amendment to Stock Purchase Agreement dated April 9, 1998 (the
          "Agreement") among Mikohn Gaming Corporation ("Mikohn"), Progressive
          Games, Inc. ("PGI") and Donald W. Jones ("Jones")

Dear Doug:

     This letter shall constitute the First Amendment to the Agreement.

     The following language from Section 11.5.4 of the Agreement shall be 
deleted in its entirety:

          The foregoing notwithstanding, prior to the Closing, PGI may
          transfer to JONES twenty (20) Gaming Tables, including all
          electronics and layouts and two (2) complete sets of spare 
          parts, at no charge to JONES for JONES's use in any legal 
          casino in which JONES holds a 50% or greater interest; 
          provided, however, JONES shall not displace any Gaming Tables
          under license from PGI in operation at such casino before
          JONES acquired a 50% interest therein. Unless prohibited by
          law or regulatory authority having jurisdiction, PGI shall
          agree to provide JONES with spare parts for such tables at
          a price of PGI's cost plus 15% and access to all improvements
          and upgrades.

     In place of the foregoing language deleted from Section 11.5.4, the 
following shall be inserted:

                    The foregoing notwithstanding, at the Closing, PGI shall 
                    transfer to JONES the Corvette and BMW automobiles owned and
                    leased, respectively, by PGI and the office furniture and
                    related items located in the office of Donald W. Jones at
                    PGI's corporate office. PGI shall transfer the automobiles
                    subject to all liens and encumbrances (including leases)
                    which JONES shall assume. At the Closing, JONES shall
                    provide MIKOHN with evidence reasonably satisfactory to it
                    that PGI will be released from all liability in respect to 
                    such liens and encumbrances. In consideration of the
                    foregoing, the Purchase Price shall be increased in an
                    amount equal the cost to extinguish all such liens and 
                    encumbrances but not in excess of $60,000.

          "Agreement") among Mikohn Gaming Corporation ("Mikohn"), Progressive
          Games, Inc. ("PGI") and Donald W. Jones ("Jones")

Dear Doug:

     This letter shall constitute the Third Amendment to the Agreement.

     1.   MIKOHN hereby agrees that prior to the Closing (as defined in the 
Agreement) PGI may sell to Jones the Note dated September 15, 1997 from August 
J. Masciotra in the principal amount of $31,000 for cash in the amount of 
$31,000 plus accrued interest on such note through the date of sale. Upon the 
sale, such note shall cease to be an "Employee Note" as such term is defined in 
the Agreement.

     2.   MIKOHN agrees that immediately prior to Closing, PGI may distribute
all or part of PGI's cash balances to JONES so long as immediately prior to such
distribution PGI has satisfied Section 11.4 of the Agreement. Such distribution
shall not cause PGI or JONES to be in breach of Section 11.4 of the Agreement.
The amount of such distribution shall not be included in PGI's cash balances on
the Closing Date reflected in Section 4.5.1.2.


                                                 Very truly yours,
