EPL Announces Second Quarter 2006 Results and Provides Update on Operations and
  Stone Energy Acquisition; Second Quarter Highlights Include Record Highs for
      Production and Revenue and 71% Exploratory Success Rate Year-to-Date

    NEW ORLEANS--(BUSINESS WIRE)--Aug. 9, 2006--Energy Partners, Ltd.
(EPL or the Company) (NYSE:EPL) today announced financial results for
the second quarter of 2006 and provided an update on operations and
its pending acquisition of Stone Energy Corporation (Stone)
(NYSE:SGY). Net income available to common stockholders was $12.6
million for the second quarter of 2006 compared to $18.1 million for
the second quarter of 2005. Net income per diluted share for the
second quarter 2006 was $0.31 compared to $0.45 per diluted share in
the same quarter a year ago. In its operational update, EPL disclosed
that it has recently drilled a discovery well at East Cameron 46,
bringing its year-to-date exploratory success rate to 71%. For the
year to date, the Company has drilled 12 discoveries out of 17
exploratory tests in the Gulf of Mexico and onshore in the Gulf Coast
region, including two discoveries in the deepwater Gulf of Mexico. The
Company also reported a new record high average production level of
28,117 barrels of oil equivalent (Boe) per day and a new record high
for revenue of $121.2 million for the second quarter of 2006.

    Stone Acquisition Update

    The acquisition of Stone was announced on June 23, 2006 and is
expected to close early in the fourth quarter. The Company noted that
EPL and Stone filed a preliminary joint proxy statement with the
Securities and Exchange Commission (SEC) on July 21, 2006 and received
clearances under the Hart-Scott-Rodino Antitrust Improvements Act
(HSR) on July 25, 2006. The Company confirmed its intention to reduce
its leverage through the repayment of acquisition related debt in an
amount approximating $700 million by the end of 2008. The reduction is
expected to come from a combination of excess cash flow and proceeds
from the disposition of non strategic properties. The Company stated
that it intends to hedge up to 80% of the projected combined
production for 2007 and 2008, implemented through a coordinated
establishment of positions with Stone to provide significant downside
protection and substantial upside participation to the market.
    Richard A. Bachmann, EPL's Chairman and CEO, commented, "Our
second quarter results reflect record levels for production and
revenue and near record levels for cash flow, along with the
challenges we face with equipment constraints and costs in the Gulf of
Mexico. We remain on track to deliver the annual production growth
target of 28,000 to 30,000 Boe per day we set for ourselves earlier
this year."
    Bachmann continued, "We are also very pleased with the progress we
are making toward our acquisition of Stone which we expect to close
early in this year's fourth quarter. We have thus far received HSR
clearance and have made our initial filings with the SEC. We intend to
continue to fast track the completion of the transaction to combine
our companies as quickly as possible and achieve the synergies and
cost savings we have previously outlined as well as pursue a number of
exciting exploitation and exploration opportunities on our combined
portfolio."

    Financial Results

    Revenue for the second quarter of 2006 rose to $121.2 million, a
new record high for the Company and a 14% increase over second quarter
2005 revenues of $106.4 million. Discretionary cash flow, which is
cash flow from operating activities before changes in working capital
and exploration expenses, rose to $98.5 million, up 28% from $77.2
million in the second quarter last year. (See reconciliation of
discretionary cash flow schedule in the tables.) Cash flow from
operating activities in the second quarter of 2006 was $111.1 million
compared with $75.1 million in the same quarter a year ago,
representing a 48% increase.
    EPL benefited from increased production volumes, record oil prices
and strong natural gas prices during the second quarter of 2006, as
well as $10.6 million in claims accrued under the Company's business
interruption insurance coverage. These benefits were reduced in the
second quarter by increased lease operating expenses due to
non-routine workover expenses and costs associated with hurricane
related repairs not covered by insurance. In addition, the Company
said higher exploration expenses in the quarter were the result of dry
hole costs, as well as significant seismic expenditures and lease
expiration write-offs. The Company said depreciation, depletion and
amortization (DD&A) expenses per Boe, which had increased to $22.78
per Boe in the first quarter of 2006 from prior periods, declined to
$19.40 in the second quarter of 2006.
    Production for the second quarter of 2006 averaged 28,117 Boe per
day, a new record high for the Company, up 22% from 22,991 Boe per day
in the first quarter of 2006, and up 4% from 27,126 Boe per day in the
second quarter of 2005. Natural gas production in the second quarter
of 2006 averaged 119.6 million cubic feet (Mmcf) per day, also a new
record high for EPL, a 26% rise from 94.8 Mmcf per day in the first
quarter of 2006. Oil production in the most recent quarter averaged
8,187 barrels per day, a 14% rise from the average of 7,185 Boe per
day in the first quarter of this year. Second quarter 2006 production
volumes were up compared to the first quarter of 2006 due to new wells
coming on line and hurricane related shut-in production continuing to
be restored. The Company estimated it has approximately 1,100 Boe per
day of hurricane shut-in production remaining, the majority of which
should be restored during the latter part of the third quarter.
    Oil price realizations for the second quarter of 2006 averaged
$61.72 per barrel, a 35% increase from $45.80 per barrel in the same
period a year ago. Natural gas price realizations in the quarter
averaged $6.90 per thousand cubic feet (Mcf), remaining essentially
flat as compared to $6.88 per Mcf in the second quarter of 2005. All
commodity prices are stated net of hedging impact. The Company
maintains a complete and regularly updated schedule of hedging
positions under "Hedging" in the Investor Relations section of the
Company's web site, www.eplweb.com.
    For the six months ended June 30, 2006, net income available to
common stockholders was $27.4 million, or $0.68 per diluted share.
This represents a 27% decrease from $37.5 million, or $0.95 per
diluted share in the same period of 2005. Discretionary cash flow for
the first two quarters of 2006 totaled $191.4 million, up 30% from
$147.4 million in the same period a year ago. (See reconciliation of
discretionary cash flow in table.) Cash flow from operating activities
in the first six months of 2006 was $174.9 million, up 21% from the
total of $144.5 million in the same period of 2005.
    For the first six months of 2006, the Company said capital
expenditures for exploration and development activities totaled $207.7
million. The Company continues to anticipate that its 2006 capital
budget for exploration and development activities will total
approximately $360.0 million, which is expected to be funded from
internally generated cash flow and does not include any costs
associated with the pending acquisition of Stone. In addition, the
Company has spent $43.5 million in acquisition costs related to the
merger agreement with Stone, which is the full amount of the break-up
fee paid to Plains Exploration and Production Company (Plains) on
behalf of Stone to terminate the merger agreement between Plains and
Stone.
    As of June 30, 2006, the Company had cash on hand of $12.9
million, total debt of $270.0 million, and a debt to total
capitalization ratio of 38%. The Company also had $105 million of
remaining capacity available under its current bank facility, which
was extended in early June to May 2011 with the redetermined borrowing
base of $225 million, up from $150 million.

    Operational Highlights

    Federal Lease Sale

    EPL has been awarded a total of 10 leases from the 11 blocks on
which the Company submitted the high bid at the March 2006 Central
Gulf of Mexico Lease Sale. The successful bids represent approximately
48,000 gross acres, including two deepwater tracts as well as eight
other areas on the Gulf of Mexico Shelf. EPL's share of the lease
bonuses for the successful high bids totaled $7.0 million.

    Gulf of Mexico and Onshore

    The Company today announced a new discovery on the Shelf, the East
Cameron 46 A-6st well. The moderate risk, moderate potential well,
drilled to a total depth of 8,800 feet and encountered high quality
natural gas pay in a single interval. The A-6st well is expected to be
on line in the third quarter of 2006. Newfield Exploration Company
(NYSE: NFX), the operator, holds a 75% working interest in the well
and EPL holds the remaining 25%. The Company also stated that an
onshore South Louisiana exploratory well at Bay Batiste in which the
Company held a 25% working interest was determined to be a dry hole.
For the year-to-date, the Company has drilled 12 discoveries out of 17
exploratory tests with eight discoveries located on the Shelf in the
Gulf of Mexico, two onshore in the Gulf Coast region, and two in the
deepwater Gulf of Mexico, for an overall success rate of 71%.
    The Company also said Thomas D. DeBrock has been named Vice
President of Exploration. Mr. DeBrock previously was the Company's
Exploration Manager in New Orleans and has been in the industry for
over 21 years and an employee of EPL since its founding.

    Current Operations

    The Company is currently drilling two exploratory wells: a high
risk, high potential Lakeside prospect onshore in Cameron Parish and a
moderate risk, moderate potential East Cameron 109 #5 well on the
Shelf. In addition, the Company said today that it plans to commence
the drilling of ten more exploratory wells before the end of year,
four of which are high potential. These totals include a deepwater
delineation well in Mississippi Canyon 292, scheduled to begin in
September or October, 2006. This moderate risk, high potential well is
the third deepwater well for the Company since the February
announcement of its entry into the deepwater Gulf of Mexico with an
agreement to acquire a 25% working interest in 23 undeveloped leases
with 13 identified prospects from Noble Energy, Inc.
    The Company also said that the installation of the permanent
platform in the South Timbalier (ST) 41/42 area is underway, which
should allow first production through the platform by early September
2006. The Company plans to bring on the ST 42#1, a 2005 discovery, and
the recent ST 42#2 discovery concurrent with the start up of
production through the new permanent platform. This will bring the
total number of producing wells in the ST 41/42 area to seven, with
plans to flow the wells through the permanent platform and through the
facilities in EPL's adjacent ST 26 field in which the Company holds a
100% interest.
    Richard A. Bachmann concluded, "With 12 discoveries in 17
exploratory tests year-to-date, two operations underway, and ten wells
left to commence drilling, we are very pleased with our exploratory
pace to date. While we have worked hard over the last several weeks to
expedite the completion of the Stone acquisition, we have not lost our
operational focus. We are very excited that the installation of the
permanent platform in the South Timbalier 41/42 area is well underway,
and are looking forward to ramping up production in that area. We are
also scheduled to bring on a number of new wells, including recent
drill wells, workover program wells, and development wells, which will
have a very positive impact on our production in the fourth quarter of
this year. We believe we are well positioned to meet our annual
production guidance of 28,000 to 30,000 Boe per day."

The table above reconciles discretionary cash flow to net cash
provided by operating activities. Discretionary cash flow is defined
as cash flow from operations before changes in working capital and
exploration expenditures. Discretionary cash flow is widely accepted
as a financial indicator of an oil and natural gas company's ability
to generate cash which is used to internally fund exploration and
development activities, pay dividends and service debt. Discretionary
cash flow is presented based on management's belief that this non-GAAP
financial measure is useful information to investors because it is
widely used by professional research analysts in the valuation,
comparison, rating and investment recommendations of companies within
the oil and natural gas exploration and production industry. Many
investors use the published research of these analysts in making their
investment decisions. Discretionary cash flow is not a measure of
financial performance under GAAP and should not be considered as an
alternative to cash flows from operating activities, as defined by
GAAP, or as a measure of liquidity, or an alternative to net income.
Investors should be cautioned that discretionary cash flow as reported
by us may not be comparable in all instances to discretionary cash
flow as reported by other companies.
