owner and operator of the Diamond Jo, LLC  ("DJL"),  which owns and operates the
Diamond Jo Casino in Dubuque,  Iowa,  and of The Old  Evangeline  Downs,  L.L.C.

SECOND QUARTER 2004 RESULTS

Consolidated Results

Consolidated  net  revenue  for the second  quarter  of 2004 was $36.6  million,
compared to $19.6  million in the second  quarter of 2003.  Consolidated  income
from  operations  during  the  second  quarter  of 2004 rose to $4.4  million as
compared to $3.7 million  reported in the second  quarter of 2003.  Consolidated
net loss to common  members'  interest for the second  quarter of 2004 was $39.7
million,  compared to $3.0 million for the second quarter of 2003. The increased
net loss was due to a loss on early  retirement  of debt of $37.6  million  as a
result of our refinancing activities discussed below.

In the second  quarter of 2004,  Peninsula  Gaming,  LLC  reported  consolidated
Adjusted  EBITDA of $7.6  million,  an increase of 61.6 percent when compared to
$4.7 million for the second  quarter 2003.  The increase is primarily due to the
opening of the casino  portion of the Evangeline  Downs  Racetrack and Casino on
December 19, 2003. (See the accompanying tables and footnotes,  which reconciles
Adjusted EBITDA to net loss from common members' interest.)

The Company ended the quarter with $30.7 million of cash (of which $27.6 million
is  unrestricted  cash  and  $3.1  million  is  restricted  cash).   Total  debt
outstanding at June 30, 2004 including the current portion,  was $274.4 million.
The  Company  incurred  $10.5  million  of  capital   expenditures   during  the
three-month  period ended June 30, 2004. Of this total,  $9.5 million related to
construction and development activities at Evangeline Downs Racetrack and Casino
and  $0.5  million  and  $0.5  million  related  to   non-construction   related
improvements and maintenance capital expenditures at DJL and OED,  respectively.
The expenditures  primarily  related to the purchase of new slot machines at the
Diamond Jo and  conversions  of slot machines at OED to  incorporate  ticket-in,
ticket-out  technology,  which we believe enhances customer service and produces
operating efficiencies.



Diamond Jo (property only)

In the second quarter of 2004,  Adjusted EBITDA at the Diamond Jo decreased over
the comparable  period of the prior year by  approximately  $0.6 million to $3.7
million. In the second quarter of 2004, net revenues at the Diamond Jo decreased
over the comparable  period of the prior year by  approximately  $0.9 million to
$12.3 million.  Net revenues decreased during the 2004 period primarily due to a
decrease in casino revenues of approximately $0.9 million.  Net revenues include
casino revenues of  approximately  $12.2 million and food and beverage and other
revenues  of  approximately  $0.8  million,   less  promotional   allowances  of
approximately $0.7 million.


Evangeline Downs Racetrack and Casino (property only)

For the second quarter of 2004, OED's Adjusted EBITDA and net operating revenues
were  approximately $3.9 million and $24.2 million,  respectively.  Net revenues
for the 2004 period  include  casino  revenues of  approximately  $16.6 million,
racing and off-track  betting revenues of approximately  $6.5 million,  and food
and beverage and other revenues of approximately $2.5 million,  less promotional
allowances of approximately $1.4 million. Results from operations of OED for the
periods  described  above are not  comparable to prior periods due to the casino
opening in December 2003.

Refinancing

On April 16, 2004,  DJL and The Old Evangeline  Downs Capital Corp.  completed a
private  placement  of $233  million 8 3/4% senior  secured  notes due 2012 in a
transaction  exempt from the registration  requirements of the Securities Act of
1933, as amended,  pursuant to Rule 144A promulgated thereunder (herein referred
to as the "Peninsula Gaming Notes"). The Peninsula Gaming Notes were issued at a
discount of approximately  $3.3 million.  Interest on the Peninsula Gaming Notes
is payable  semi-annually on April 15 and October 15 of each year,  beginning on
October 15, 2004.

The Company used the net proceeds from the sale of the Peninsula Gaming Notes as
follows (all payments based on outstanding balances as of April 16, 2004): 1) to
redeem all of DJL's existing  senior secured notes in an amount  (including call
premium and accrued interest) of approximately  $79.9 million;  2) to repurchase
OED's senior  secured  notes in an amount  (including  tender  premium,  accrued
interest and contingent  interest) of  approximately  $134.6 million;  3) to pay
accrued    distributions    on   DJL's    outstanding    preferred    membership
interests-redeemable  of approximately $1.1 million;  4) to pay related fees and
expenses of approximately $13.4 million;  and 5) for general corporate purposes.
As a result of the issuance of the Peninsula  Gaming Notes,  DJL incurred a loss
of approximately  $8.7 million consisting of the write-off of deferred financing
fees of  approximately  $2.0  million,  the payment of a call premium on the DJL
senior secured notes of approximately  $5.7 million,  interest on the DJL senior
secured  notes of  approximately  $0.7 million and write-off of bond discount of
approximately $0.3 million. In connection therewith, OED also incurred a loss of
approximately  $27.9 million  consisting of the write-off of deferred  financing
fees of approximately  $8.4 million,  the payment of a tender premium on the OED
senior secured notes of approximately $16.3 million,  write-off of bond discount
of approximately $2.1 million and consent fees of approximately $1.1 million. In
addition,  the Company wrote off $0.9 million of deferred financing fees related
to the credit facilities discussed below.

                                       -2-



On June 16, 2004, DJL and OED jointly entered into a Loan and Security Agreement
with Wells  Fargo  Foothill,  Inc.  as the  Arranger  and Agent (the "PGL Credit
Facility").  The PGL Credit  Facility  consists of a revolving  credit  facility
which  permits DJL and OED to request  advances  and letters of credit up to the
lesser of the maximum  revolver amount of $35 million (less amounts  outstanding
under letters of credit) and a specified  borrowing base.  Immediately  upon the
closing of the PGL Credit  Facility,  the Company borrowed  approximately  $14.9
million to  refinance  outstanding  obligations  under DJL's and OED's  existing
senior credit facilities and pay financing related fees and expenses.


The PGL Credit  Facility also contains a Term Loan in the amount of $14,666,667.
The proceeds from the Term Loan were used to repay outstanding obligations under
the OED's existing furniture, fixtures and equipment credit facility.

As of June 30, 2004, the Company had $14.9 million and $14.7 million outstanding
under the  revolver  portion and Term Loan  portion of the PGL Credit  Facility,
respectively.  In  addition,  as of June 30, 2004,  the Company had  outstanding
letters of credit of approximately $3.5 million.
