     On June 8, 1999, the Company issued $200,000 of Senior Subordinated Notes
due 2009 ("Subordinated Notes") and entered into a five year $200,000 Senior
Secured revolving bank credit agreement ("Credit Facility"). The Credit Facility
is secured by liens on substantially all of the Company's assets and the
Company's subsidiaries are co-borrowers. The Company's joint-venture subsidiary
that operates the Argosy Casino Lawrenceburg is not a co-borrower nor are the
assets of the subsidiary pledged. All of the Company's wholly-owned operating
subsidiaries guarantee the Subordinated Notes. The Company's joint-venture
subsidiary that operates the Argosy Casino Lawrenceburg does not guarantee the
Subordinated Notes. The Subordinated Notes rank junior to all of the senior
indebtedness of the Company, including borrowings under the Credit Facility.

     The Subordinated Notes and the Credit Facility contain certain restrictions
on the payment of dividends on the Company's common stock and the inccurrence of
additional indebtedness, as well as other customary debt covenants. In addition,
the Credit Facility requires the Company to maintain certain financial ratios.

     During June 2000, the Company redeemed the remaining outstanding $22.2
million 13 1/4% First Mortgage Notes due 2004. As required by the Credit
Facility, the Company had placed $26.7 million in escrow to fund the remaining
interest payments and June 2000 redemption. In connection with this early
extinguishment of the Mortgage Notes, the Company recorded an extraordinary loss
of $1.2 million. The extraordinary loss is net of an income tax benefit of $0.8
million.

4.   SUBSIDIARY GUARANTORS

     The Company has outstanding at September 30, 2000, $41.0 million under a
$200 million Credit Facility ("Credit Facility"). The Company also has
outstanding $200 million of Senior Subordinated Notes due 2009 ("Subordinated
Notes").

     The Credit Facility is secured by a first lien on substantially all of the
Company's assets and the Company's subsidiaries are co-borrowers. The Company's
joint-venture subsidiary that operates the Argosy Casino Lawrenceburg is not a
co-borrower nor are the assets of the subsidiary pledged. The Subordinated Notes
are guaranteed, on a joint and several basis, by the following wholly-owned
subsidiaries of the Company: Alton Gaming Company, The Missouri Gaming Company,
The St. Louis Gaming Company, Iowa Gaming Company, Jazz Enterprises, Inc.,
Argosy of Louisiana, Inc., Catfish Queen Partnership in Commendam, The Indiana
Gaming Company and the Belle of Sioux City Casino (the "Guarantors"). The
Company's joint-venture subsidiary that operates the Argosy Casino & Hotel
Lawrenceburg is not a guarantee of the Subordinated Notes. The Subordinated
Notes rank junior to all of the senior indebtedness of the Company, including
borrowings under the Credit Facility.

     In July 2000, the Company purchased the 30% minority interest in the Belle
of Sioux City Casino. At the time of our purchase, the Belle of Sioux City
Partnership became a co-borrower under the Credit Facility and a guarantor of
the Subordinated Notes. The Belle of Sioux City Partnership is presented as a
Guarantor for 2000 and as a Non-Guarantor for 1999 in the following tables.

     The following tables present summarized balance sheet information of the
Company as of September 30, 2000 and December 31, 1999 and summarized operating
statement information for the nine and three months ended September 30, 2000 and
1999. The column labeled "Parent Company" represents the holding company for
each of the Company's direct subsidiaries, the column labeled "Guarantors"
represents each of the Company's direct subsidiaries, all of which are
wholly-owned by the parent company, and the column labeled "Non-Guarantors"
represents the Partnership which operates the Company's casino in Lawrenceburg,
Indiana. The Company believes that separate financial statements and other
disclosures regarding the Guarantors, except as otherwise required under
Regulation S-X, are not material to investors.

5.   WRITE DOWN OF ASSETS

     During December 1999, we replaced our landing facility at our Alton
property. In June 2000, the Company recorded a $6.8 million pre-tax charge to
write down the previous landing facility as it was determined the Company has no
planned use for the landing facility.


6.   COMMITMENTS AND CONTINGENT LIABILITIES

     LAWRENCEBURG, INDIANA --Under terms of the Lawrenceburg partnership
agreement, effective December 10, 1999, each limited partner has the right ("Put
Rights") to sell its interest to the other partners (pro rata in accordance with
their respective percentage interests). Both Conseco Entertainment, L.L.C., a
29% limited partner and Centaur, Inc., a 13.5% limited partner in the Indiana
Partnership ("Selling Partner"), notified Argosy ("Non-Selling Partners") that
they were exercising their irrevocable Put Rights to sell their limited
partnership interests. Under terms of the partnership agreement, the Partners
have 60 days to negotiate a sales price. When the price is not agreed to within
60 days, the Selling Partners and the Non-Selling Partners each hired appraisers
to determine the purchase price. Upon the conclusion of the appraisal process,
if the Non-Selling Partner elects not to pay appraised value, the Indiana
Partnership must be sold in its entirety.

     DEFERRED ACQUISITION COSTS - Included in other assets at September 30, 2000
is approximately $0.7 million of deferred acquisition costs associated with our
efforts to purchase the Indiana Partnership minority interests. Should we be
unable to acquire the minority partnership interests and therefore under the
terms of the Partnership Agreement be required to sell the Indiana Partnership,
these deferred costs would be charged against the proceeds from the sale of our
majority Indiana Partnership interest.

     The Company is subject, from time to time, to various legal and regulatory
proceedings, in the ordinary course of business. The Company believes that
current proceedings will not have a material effect on the financial condition
of the Company or the results of its operations.

     EXCEPT WHERE OTHERWISE NOTED, THE WORDS, "WE," "US," "OUR" AND SIMILAR
TERMS, AS WELL AS REFERENCES TO "ARGOSY" OR THE "COMPANY" REFER TO ARGOSY GAMING
COMPANY AND ALL OF ITS SUBSIDIARIES.


OVERVIEW

     Through our subsidiaries or joint ventures, we own and operate the Alton
Belle Casino, in Alton, Illinois; the Argosy Casino in Riverside, Missouri; the
Argosy Casino in Baton Rouge, Louisiana; the Belle of Sioux City Casino in Sioux
City, Iowa; and the Argosy Casino in Lawrenceburg, Indiana. In July 2000, the
Company completed the purchase of the 30% minority interest in the Belle of
Sioux City Casino at which time the Belle of Sioux City became a wholly-owned
subsidiary.

     Our results of operations for the nine and three months ended September 30,
2000 reflect increases in both revenues and operating income at all of our
casino properties over amounts from comparable 1999 periods. This improvement is
attributable to the successful implementation of our operating strategy, which
has been developed with the goal to position us as the premier riverboat casino
operator, and to favorable regulatory changes in Illinois, Louisiana and
Missouri.

     During December 1999, we replaced our landing facility at our Alton
property. In June 2000, the Company recorded a $6.8 million pre-tax charge to
write down the previous landing facility as it was determined the Company has no
planned use for the landing facility.

     During the second quarter of 2000, the Company recorded an extraordinary
loss of $1.2 million (net of a $0.8 million tax benefit) related to the
redemption of its remaining $22.2 million of outstanding First Mortgage Notes.

(1)  Income from operations and EBITDA are presented before consideration of any
     management fee paid to us, before the Lawrenceburg 42.5% minority interest
     and before the Sioux City 30% minority interest for the period prior to our
     July 2000 acquisition of this 30% minority interest.

(2)  Excludes a $6.8 million pre-tax charge related to the write-off of assets
     for the nine months ended September 30, 2000.

(3)  "EBITDA" is defined as earnings before interest, taxes, depreciation and
     amortization and is presented before any management fees paid to Argosy.
     EBITDA should not be construed as an alternative to operating income, or
     net income (as determined in accordance with generally accepted accounting
     principles) as an indicator of our operating performance, or as an
     alternative to cash flows generated by operating, investing and financing
     activities (as an indicator of cash flow or a measure of liquidity). EBITDA
     is presented solely as a supplemental disclosure because management
     believes that it is a widely used measure of operating performance in the
     gaming industry and for companies with a significant amount of depreciation
     and amortization. EBITDA may not be comparable to similarly titled measures
     reported by other companies. We have other significant uses of cash flows,
     including debt service and capital expenditures, which are not reflected in
     EBITDA.

(4)  The Lawrenceburg partnership pays a financial advisory fee equal to 5.0% of
     its EBITDA to a minority partner.

nine months ended September 30, 1999. The western properties (Alton, Riverside,
Sioux City and Baton Rouge) reported an aggregate 31.5% increase in casino
revenues from $182.0 to $239.4 million. In particular, Alton casino revenues
increased from $61.5 to $85.8 million, Riverside casino revenues increased from
$61.7 to $73.0 million, Sioux City casino revenues increased from $20.0 to $26.4
million, and Baton Rouge casino revenues increased from $38.8 to $54.2 million.
Lawrenceburg casino revenues increased $32.7 million, or 14.2%, to $263.0
million for the nine months ended September 30, 2000, from $230.3 million over
the nine months ended September 30, 1999. Each of our casinos reported increases
in passengers as well as an increase in the average win per passenger for the
nine months ended September 30, 2000 versus the nine months ended September 30,
1999. This increase in revenues was partially attributable to favorable
regulatory changes in Illinois, Missouri and Louisiana.

     Casino expenses increased $33.0 million to $219.0 million for the nine
months ended September 30, 2000 from $186.0 million for the nine months ended
September 30, 1999. This increase is due to increased gaming and admission taxes
at all properties totaling $21.7 million and increases in other casino expenses
of $11.3 million at all properties due to increases in overall revenues and
admissions at all properties.

     ADMISSIONS--Admissions revenues (net of complimentary admissions) increased
slightly by $0.8 million to $14.8 million for the nine months ended September
30, 2000 from $14.0 million for the nine months ended September 30, 1999.
Although the number of admissions increased, more complimentary admissions were
given to customers as part of Lawrenceburg's marketing program.

     FOOD, BEVERAGE AND OTHER--Food, beverage and other revenues increased $7.4
million to $50.3 million for the nine month period ended September 30, 2000 from
$42.9 million for the nine months ended September 30, 1999. This increase is
primarily attributable to a $4.7 million increase at Lawrenceburg and a $1.6
million increase at Alton. Food, beverage and other net profit improved $4.8
million to $17.2 million for the nine months ended September 30, 2000 from $12.4
million for the nine months ended September 30, 1999.

     For the nine months ended September 30, 2000, the Lawrenceburg hotel
generated $3.0 million in net revenues and $1.1 million of operating profit. The
hotel occupancy percentage was 90% and the average daily room rate including
promotional allowances was $86. For the nine months ended September 30, 1999,
the Lawrenceburg Hotel generated $3.2 million in net revenues and $1.5 million
of operating profit. The hotel occupancy rate was 83% and the daily room rate
including promotional allowances was $84. The decrease in hotel net revenues and
operating profit reflects an increase in complimentary rooms to our customers.

     SELLING, GENERAL AND ADMINISTRATIVE--Selling, general and administrative
expenses increased $18.2 million to $105.3 million for the nine months ended
September 30, 2000 from $87.1 million for the nine months ended September 30,
1999, due primarily to an increase of $8.3 million at Lawrenceburg related to
additional payments required to be paid to the city as a result of increased
gaming revenue and expanded advertising and marketing efforts, a $1.8 million
increase in rent expense in Riverside and $5.9 million of increase costs at our
other properties primarily relating to expanded promotions. Selling, general and
administrative expenses for the nine months ended September 30, 1999 included
$1.8 million due to expenses related to a severance package and settlement
arrangement.

     OTHER OPERATING EXPENSES--Other operating expenses increased by $2.2
million to $22.6 million for the nine months ended September 30, 2000 from $20.4
million for the nine months ended September 30, 1999 due to increases
attributable to the overall increase in revenues.

     DEPRECIATION AND AMORTIZATION--Depreciation and amortization increased $1.3
million to $27.0 million for the nine months ended September 30, 2000 from $25.7
million for the nine months ended September 30, 1999, due primarily to an
increase of $1.2 million at Alton for depreciation on the new landing facility
placed in service in December 1999.

     INTEREST EXPENSE--Net interest expense decreased $9.8 million to $26.3
million for the nine months ended September 30, 2000 from $36.1 million for the
nine months ended September 30, 1999. This decrease is primarily attributable to
a refinancing completed during June 1999, which lowered the average borrowing
rate and increased our flexibility to use cash flows to lower our average
outstanding debt balances. There was also a significant decrease in interest
expense to our minority partner in Lawrenceburg.

     MINORITY INTERESTS - Our minority interest expense increased by $5.0
million to $31.0 million for the nine months ended September 30, 2000 from $26.0
million for the nine months ended September 30, 1999. This increase is primarily
attributable to improved income at our Indiana Partnership.

     INCOME TAX EXPENSE - Income tax expense increased by $20.7 million to $22.5
million for the nine months ended September 30, 2000 from $1.8 million for the
nine months ended September 30, 1999. During the nine months ended September 30,
2000, and 1999, we recorded income tax expense at effective rates of 40% and
15%, respectively. Income tax expense for the nine months ended September 30,
1999 was significantly reduced by the utilization of net operating loss carry
forwards generated in 1996 and 1997.

     EXTRAORDINARY LOSS - The Company recorded an extraordinary loss of $1.2
million for the nine months ended September 30, 2000 related to the completion
of the final phase of the 1999 refinancing. This extraordinary loss is net of a
$0.8 million tax benefit. During the nine months ended September 30, 1999, the
Company recorded an extraordinary loss of $34.8 million related to the early
extinguishment of debt in conjunction with the completion of its June 1999
refinancing. The extraordinary loss in 1999 was not recorded net of a tax
benefit as the Company was in a net operating loss position.

THREE MONTHS ENDED SEPTEMBER 30, 2000 COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 1999

     CASINO--Casino revenues for the three months ended September 30, 2000
increased $24.9 million, or 16.8%, to $172.2 million for the three months ended
September 30, 2000 from $147.3 million for the three months ended September 30,
1999. The western properties (Alton, Riverside, Sioux City and Baton Rouge)
reported an aggregate 21.0% increase in casino revenues from $67.0 to $81.0
million. In particular, Alton casino revenues increased from $23.4 to $29.4
million, Riverside casino revenues increased from $21.7 to $24.6 million, Sioux
City casino revenues increased from $7.4 to $8.8 million, and Baton Rouge casino
revenues increased from $14.5 to $18.2 million. Lawrenceburg casino revenues
increased $10.8 million, or 13.4%, to $91.1 million for the three months ended
September 30, 2000 from $80.3 million for the three months ended September 30,
1999. Each of our casinos reported increases in passengers as well as an
increase in the average win per passenger for the three months ended September
30, 2000 versus the three months ended September 30, 1999. This increase was
partially attributable to favorable regulatory changes in Missouri.

     Casino expenses increased $9.6 million to $75.2 million for the three
months ended September 30, 2000 from $65.6 million for the three months ended
September 30, 1999. This increase is due to increased gaming and admission taxes
at all properties totaling $6.0 million and increases in other casino expenses
of $3.6 million at all properties due to increases in overall revenues and
admissions at all properties.

     ADMISSIONS--Admissions revenues (net of complimentary admissions) remained
stable at $5.1 million for the three months ended September 30, 2000 and 1999.
Although the number of admissions increased, more complimentary admissions were
given to customers as part of Lawrenceburg's marketing program.

     FOOD, BEVERAGE AND OTHER--Food, beverage and other revenues increased $2.3
million to $17.6 million for the three month period ended September 30, 2000
from $15.3 million for the three month period ended September 30, 1999. Food,
beverage and other net profit improved $0.5 million to $5.2 million for the
three months ended September 30, 2000 from $4.7 million for the three months
ended September 30, 1999.

     For the three months ended September 30, 2000, the Lawrenceburg hotel
generated $1.1 million in net revenues and $0.4 million of operating profit. The
hotel occupancy percentage was 96% and the average daily room rate including
promotional allowances was $88. For the three months ended September 30, 1999,
the Lawrenceburg hotel generated $1.3 million in net revenues and $0.8 million
of operating profit. The hotel occupancy percentage was 89% and the average
daily room rate including promotional allowances was $91. The decrease in hotel
net revenues and operating profit reflects an increase in complimentary rooms to
our customers.

     SELLING, GENERAL AND ADMINISTRATIVE--Selling, general and administrative
expenses increased $6.7 million to $36.8 million for the three months ended
September 30, 2000 from $30.1 million for the three months ended September 30,
1999, due primarily to an increase at Lawrenceburg of $1.4 million related to
additional payments required to be paid to the city as a result of increased
gaming revenue and $0.9 million due to expanded advertising and marketing
efforts, a $0.6 million increase in rent expense in Riverside and $1.6 million
of increased costs at our other properties relating to expanded promotions.

     OTHER OPERATING EXPENSES--Other operating expenses increased by $0.5
million to $7.6 million for the three months ended September 30, 2000 as
compared to $7.1 million for the three months ended September 30, 1999 due to
increases attributable to the overall increase in revenues.

     DEPRECIATION AND AMORTIZATION--Depreciation and amortization increased $0.3
million from $8.6 million for the three months ended September 30, 1999 to $8.9
million for the three months ended September 30, 2000.

million for the three months ended September 30, 2000 from $10.0 million for the
six months ended September 30, 1999. This decrease is primarily attributable to
a refinancing completed during June 1999, which lowered the average borrowing
rate and increased our flexibility to use cash flows to lower our average
outstanding debt balances. There was also a significant decrease in interest
expense to our minority partner in Lawrenceburg.

     MINORITY INTERESTS - Our minority interest expense increased by $0.8
million to $10.8 million for the three months ended September 30, 2000 as

     EXTRAORDINARY LOSS - The Company recorded an extraordinary loss of $3.7
million for the three months ended September 30, 1999 related to its completion
of the June 1999 refinancing.


COMPETITION

     Our Alton Casino faces competition from four other riverboat casino
operators in the St. Louis area. Our Riverside Casino faces competition from
three casino companies in the Kansas City area. Our Baton Rouge Casino faces
competition from one casino located in downtown Baton Rouge, a nearby Native
American casino and multiple casinos throughout Louisiana. We face competition
in Sioux City, Iowa from video gaming devices in nearby South Dakota, from two
land-based Native American casinos and, to a lesser extent, from slot machines
at a pari-mutual race track in Council Bluffs, Iowa and from two riverboat
casinos in the Council Bluffs, Iowa/Omaha, Nebraska market. The Indiana
Partnership faces competition from two riverboat casinos in the Cincinnati
market, the second of which opened in October 2000. In addition, The Indiana
Partnership competes with a riverboat casino in the Louisville, Kentucky area
approximately 100 miles from our Lawrenceburg facility. There could be further
unanticipated competition in any market which we operate as a result of
legislative changes or other events. We expect each market in which we
participate, both current and prospective, to be highly competitive.

LIQUIDITY AND CAPITAL RESOURCES

     In the nine months ended September 30, 2000, we generated cash flows from
operating activities of $134.6 million compared to $94.3 million for the same
period in 1999. This increase is attributable to improved operations at each of
our five casino locations.

     In the nine months ended September 30, 2000, we used cash flows for
investing activities of $32.2 million compared to $17.6 million for the nine
months ended September 30, 1999. In the nine months ended September 30, 2000,
$9.1 million in cash flows were used to purchase the minority interest in the
Sioux City Partnership. The primary use of cash flows in both the nine months
ended September 30, 2000 and 1999 were for purchases of property and equipment.
During the nine months ended September 30, 2000, $9.9 million of cash flows were
used to fund progress payments to construct the Baton Rouge Hotel.

                                   (continued)


     During the nine months ended September 30, 2000, we used $99.9 million in
cash flows for financing activities compared to using $128.9 million of cash
flows for financing activities for the same period in 1999. During the nine
months ended September 30, 2000, $62.8 million in cash flows were used to make
repayments on the line of credit. Cash flows in both 2000 and 1999 were used for
repayment of long-term debt, repayment of partner loans, and distributions
related to the Lawrenceburg partnership. Sources of cash during the nine months
ended September 30, 1999 included proceeds from the issuance of subordinated
notes and borrowings on the line of credit.

     At September 30 , 2000, we had approximately $49.6 million of cash and cash
equivalents, including approximately $28.0 million held at the Indiana
Partnership. During June 2000, the Company redeemed the remaining $22.2 million
of First Mortgage Notes that were not tendered in the June 1999 refinancing. The
Company had previously placed $25.2 million in escrow to fund the June 2000
redemption. At September 30, 2000, we had outstanding $200.0 million of Senior
Subordinated Notes, which were issued in June 1999 and are due in June 2009 and
$41.0 million on a senior secured revolving credit facility. As of November 6,
2000 availability under the credit facility was approximately $169 million.

     We have made a significant investment in property and equipment and plan
to make significant additional investments at certain of our existing
properties. In 2000, we expect maintenance capital expenditures primarily
related to the purchase of new gaming product and facility enhancements to be
approximately $19.0 million, and expenditures related to the Baton Rouge
hotel and other project capital expenditures to be approximately $26.0
million.

     Both of our partners in the Indiana Partnership have exercised their put
rights under terms of the Lawrenceburg Partnership agreement. Ultimately we will
have the right to purchase the selling partners' interests. If we elect to
purchase the minority interest, a significant portion of this purchase could be
funded through existing credit facilities. However, we will be required to fund
a portion of the purchase by obtaining additional debt or equity financing. No
assurance can be given that we would be able to obtain such additional financing
on favorable terms.

PART II.  OTHER INFORMATION

Item 1.   LEGAL PROCEEDINGS -

     The Company is from time to time a party to legal proceedings arising in
the ordinary course of business. Other than as disclosed below, the Company is
unaware of any legal proceedings, which, even if the outcome were unfavorable to
the Company, would have a material adverse impact on either its financial
condition or results of operations.

MATTERS PERTAINING TO INTERIM HOLDINGS, L.L.C. AND ARGOSY GAMING COMPANY, ET AL

     On January 6, 2000, the Company was named as a defendant in a lawsuit
filed by Interim Holdings, L.L.C., in the Circuit Court of St. Louis County,
Missouri, in a case styled INTERIM HOLDINGS, L.L.C. V. ARGOSY GAMING CO., ET
AL.. The Company removed the lawsuit to the federal district court for the
Eastern District of Missouri. On April 13, 2000, the federal district court
remanded the lawsuit back to the Circuit Court of St. Louis County. The
lawsuit is styled as a "bill in equity." It concerns a purchase agreement and
consulting agreement entered into between Argosy and St. Louis Concessions,
Inc. ("SLC"), as part of Argosy's attempt to purchase certain assets
including assuming a lease for a gaming facility in downtown St. Louis. The
lawsuit alleges that Argosy's loans pursuant to the purchase agreement to SLC
and consulting payments to WPW Ventures, Inc. ("WPW") defrauded creditors of
Floyd C. Warmann, an individual with an ownership interest in SLC and WPW.
The Company filed a Motion to Dismiss the lawsuit on July 5, 2000. The Court
denied that Motion to Dismiss on August 21, 2000 and ordered the parties to
proceed with discovery into the lawsuit. That discovery is ongoing.
Management believes that the claims are without merit and that the legal
bases for the suit are unsupportable. Further, Management does not expect
that the lawsuit will have a material adverse effect on the Company's
financial position or results of operations.

     On September 13, 2000, the Company filed suit against John C. Foley and
the company that he controls, Interim Holdings, L.L.C. (collectively
"defendants") in the federal district court for the Southern District of
Illinois, in a case styled ARGOSY GAMING CO. V. FOLEY, ET AL.. On October 3,
2000, Argosy served discovery requests on the defendants. On October 25,
2000, the defendants filed a Motion to Dismiss the lawsuit, a Motion to Stay
the lawsuit pending the outcome of the Missouri lawsuit, and objections to
Argosy's discovery requests. The lawsuit alleges six counts against the
defendants based on communications that they made to third parties regarding
Argosy's actions. The counts allege trade disparagement, fraud, interference
with business advantage, deceptive trade practices, defamation, and false
light defamation. Argosy seeks a court order restricting the defendants from
making further statements impugning Argosy's good name and business
reputation. Argosy also seeks unspecified monetary damages. Argosy will be
responding to the motions filed by the defendants.

             LAWRENCEBURG PARTNERSHIP APPRAISAL LITIGATION

BACKGROUND

     Under the terms of the Amended and Restated Partnership Agreement
("Partnership Agreement") for Indiana Gaming Company, L.P. (the
"Partnership") among Conseco Entertainment, L.L.C. ("Conseco") and Centaur,
Inc. ("Centaur"), the limited partners in the Partnership, The Indiana
Gaming Company, the general partner of the Partnership and a wholly-owned
subsidiary of the Company ("Indiana Gaming") after December 10, 1999 each
limited partner of the Partnership has the right to sell its entire interest
in the Partnership to the remaining partners. On April 28, 2000 Conseco
exercised this right and gave its irrevocable notice to Indiana Gaming and
Centaur ("Put Notice").

     The Partnership Agreement provides that after Conseco gave its Put
Notice that Conseco (sometimes herein referred to as, a "Selling Partner")
and Indiana Gaming and Centaur (sometimes herein collectively referred to as
"Non-Selling Partners") had 60 days to attempt in good faith to negotiate the
purchase price for the Selling Partner's interest. In the event within such
60 day period the parties could not agree upon a purchase price for the
Selling Partner's interest, the Partnership Agreement provides that the
purchase price of the Selling Partner's interest shall be determined by an
appraisal process. The appraisal process requires that the Selling Partner
and Non-Selling Partners each select an independent nationally recognized
appraisal firm with expertise in the gaming industry. The Selling Partner
selected PricewaterhouseCoopers LLP ("PWC") and the Non-Selling Partners
selected Houlihan Lokey Howard & Zakin ("HLHZ"). If the appraised purchase
prices of the two appraisers are within 10% of one another then the appraisal
price is the average of the two and if the two appraisals are more than 10%
apart then a third independent appraiser is selected by PWC and HLHZ and the
appraisal price is the average of the three appraisals. Once the price is
determined by appraisal (either by the two appraisers or the three
appraisals) the Non-Selling Partners have 60 days to elect to purchase the
Selling Partner's interest at the appraised price. If the Non-Selling
Partners fail to elect to purchase the Selling Partner's interest at the
appraised price THEN the entire Partnership and its assets are to be
auctioned to the highest bidder.

     On September 18, 2000 Centaur also exercised its put rights for its
partnership interest.

TIPPECANOE COUNTY, INDIANA LITIGATION

     CONSECO ENTERTAINMENT, L.L.C., PLAINTIFF V. INDIANA GAMING COMPANY,
L.P., THE INDIANA GAMING COMPANY, CENTAUR, INC. AND RJ INVESTMENTS, INC.,
Defendants filed in the Tippecanoe Superior Court in Tippecanoe County,
Indiana, case no. #79D01-0006-CP-235.

     On June 14, 2000 Conseco filed the above-captioned cause of action
seeking a declaratory judgment with respect to certain timing provisions of
the Partnership Agreement relating to the appraisal process. Essentially,
Conseco seeks an interpretation of the Partnership Agreement that the
negotiation period between the parties, the appraisal process and the 60 days
after the appraisal process to elect to purchase the Selling Partner's
interest, and the closing on the sale of the interest if the Non-Selling
Partners elect to purchase must be concluded within 6 months from the date of
the Put Notice or October 28, 2000. The Company's interpretation of the
Partnership Agreement is that the applicable 6 month period within which the
Non-Selling Partners must consummate the purchase of the Selling Partner's
interest begins when the purchase price is determined by the appraisal
process.

     Conseco selected PWC to appraise its interest. PWC is also Conseco,
Inc.'s, the parent of Conseco, independent public accounting firm. PWC's
appraisal (a signed and certified copy of which has never been delivered to
the Company) purports to appraise Conseco's interest at $356 million. In the
Illinois litigation discussed below, Indiana Gaming is challenging both the
independence of PWC and the validity of the PWC appraisal. The Illinois
litigation alleges that among the numerous errors in PWC's appraisal is its
assumption that the Partnership adds a fourth floor to the existing
Lawrenceburg facility and PWC uses the earnings of this hypothetical fourth
floor to arrive at its value. PWC fails to recognize that from a structural
and regulatory point of view a fourth deck is probably not feasible. HLHZ,
the appraiser selected by the Non-Selling Partner, appraised Conseco's
interest at $229,513,000. PWC and HLHZ had agreed upon the third appraiser if
one was necessary, however, to date the third appraisal firm which was
selected by PWC and HLHZ has not commenced work.

     On October 6, 2000 Conseco filed a petition with the Court in this
action seeking among other things, that the appraised value be determined by
just using the average of the PWC and HLHZ appraised prices rather than
obtain a third appraiser and for the Court to appoint an independent party to
conduct the auction process if necessary, rather than have Indiana Gaming
conduct the process. This petition along with Conseco's motion for summary
judgment was to have been heard by the Tippecanoe County Court on October 26,
2000, however, due to an order issued by the Illinois Supreme Court on
October 25, 2000 in the below described Illinois litigation, the Tippecanoe
County Court declined to hear arguments or take any action on these matters.
On October 27, 2000 the judge in the Tippecanoe County Case decided, on his

ILLINOIS LITIGATION

     THE INDIANA GAMING COMPANY V. CONSECO ENTERTAINMENT, L.L.C., CENTAUR,
INC. AND RJ INVESTMENTS, INC. pending in the Circuit Court for Madison
County, Illinois case no. 00 MR 411.

     On September 5, 2000 Indiana Gaming filed the above action seeking a
declaratory judgment that pursuant to the terms of the Partnership Agreement
that Indiana Gaming is an eligible bidder in any auction of the Partnership
in the event the Non-Selling Partners fail to buy the Selling Partner's
interest after the appraisal process. On September 11, 2000 Indiana Gaming
filed an Amended Complaint seeking not only the declaratory judgment but also
alleging a breach of contract claim against Conseco with respect to its
conduct in connection with the appraisal process and seeks, among other
things, to have the PWC appraisal declared invalid. On September 25, 2000
Conseco removed the action from Madison County, Illinois to the United States
District Court, Southern District of Illinois. Indiana Gaming filed a motion
for remand to Madison County, Illinois and on October 10, 2000 the case was
remanded to Madison County, Illinois. Indiana Gaming filed a Motion for a
Preliminary Injunction to enjoin Conseco from prosecuting its petition
referred to above in the Tippecanoe County case. On October 18, 2000 the
Court held a hearing regarding the injunction and entered a preliminary
injunction enjoining Conseco from prosecuting its Indiana petition, but
permitting Conseco to proceed with its declaratory judgment relief as to the
interpretation of the timing provision in the Partnership agreement. The
Madison County Circuit Court then issued a second order requiring Conseco to
withdraw its petition in the Tippercanoe County case. On October 24, 2000
Conseco filed with the Illinois Supreme Court a Motion for Supervisory Order
and an Emergency Motion to Stay Enforcement of the Circuit Court's orders
which was granted by the Illinois Supreme Court that day. On October 25, 2000
Indiana Gaming filed a Motion to Vacate the stay order which was granted that
day and the Illinois Supreme Court ordered a "status quo" of all proceedings
by the parties pending a review and hearing before the Illinois Supreme
Court. As of November 10, 2000 no hearing before the Illinois Supreme Court
has been scheduled.
