Forward-Looking Statements
2
Information included herein contains forward-looking statements that involve
significant risks and uncertainties, including our need to replace production and
acquire or develop additional oil and gas reserves, intense competition in the oil
and gas industry, our dependence on our management, volatile oil and gas
prices and costs, uncertain effects of hedging activities and uncertainties of our
oil and gas estimates of proved reserves and resource potential, all of which
may be substantial.  In addition, past performance is no guarantee of future
performance or results.  All statements or estimates made by the Company,
other than statements of historical fact, related to matters that may or will occur
in the future are forward-looking statements.
Readers are encouraged to read our December 31, 2010 Annual Report on
Form 10-K and any and all of our other documents filed with the SEC regarding
information about GeoResources for meaningful cautionary language in respect
of the forward-looking statements herein.  Interested persons are able to obtain
copies of filings containing information about GeoResources, without charge, at
the SEC’s internet site (http://www.sec.gov). There is no duty to update the
statements herein.

EUR refers to management’s internal estimates of reserves potentially recoverable from successful drilling of wells. These estimates do not necessarily represent reserves
as defined under SEC rules and by their nature and accordingly are more speculative and substantially less certain of recovery and no discount or risk adjustment is
included in the presentation. Actual locations drilled and quantities that may be ultimately recovered from the Company’s interests could differ substantially.

expense and further excludes non-cash compensation, impairments, hedge ineffectiveness and income or loss on derivative contracts.  Adjusted EBITDAX should not be considered as an
alternative to net income (as an indicator of operating performance) or as an alternative to cash flow (as a measure of liquidity or ability to service debt obligations) and is not in accordance with,
nor superior to, generally accepted accounting principles, but provides additional information for evaluation of our operating performance.

Additional Disclosures
34
In April 2007, GeoResources, Inc. (“GEOI” or the “Company”) merged with Southern Bay Oil & Gas, L.P. (“Southern Bay”) and a
subsidiary of Chandler Energy, LLC and acquired certain oil and gas properties (collectively, the “Merger”).  The Merger was
accounted for as a reverse acquisition of GEOI by Southern Bay.  Therefore, any information prior to 2007 relates solely to Southern
Bay. 
Cautionary Statement – The SEC has established specific guidelines related to reserve disclosures, including prices used in
calculating PV 10% and the standardized measure of discounted future net cash flows.  PV 10% is not a measure of financial or
operating performance under General Accepted Accounting Principles (GAAP), nor should it be considered in isolation or as a
substitute for the standardized measure of discounted future net cash flows as defined under GAAP.  In addition, alternate pricing
methodologies, such as the NYMEX forward strip price curve, are not provided for under SEC guidelines and therefore do represent
GAAP.
PV-10% is not a measure of financial or operating performance under GAAP, nor should it be considered in isolation or as a
substitute for the standardized measure of discounted future net cash flows as defined under GAAP.  PV-10 % for SEC price
calculations are based on the 12-month unweighted average prices at year-end 2010 of $79.43 per Bbl for oil and $4.37 per Mmbtu
for natural gas.  These prices were adjusted for transportation, quality, geographical differentials, marketing bonuses or deductions 
and other factors affecting wellhead prices received.  For the Strip Price reserve case, five year NYMEX strip pricing at 12/30/10 was
utilized for 2011 – 2015.   NYMEX oil strip ranged from $93.85 per Bbl to $92.48 per Bbl and then constant thereafter.  NYMEX gas
strip ranged from $4.59 per Mmbtu to $5.64 per Mmbtu and then held constant thereafter. These prices were adjusted for
transportation, quality, geographical differentials, marketing bonuses or deductions  and other factors affecting wellhead prices
received.  Actual realized prices will likely vary materially from the NYMEX strip. The Company’s independent engineers are Cawley,
Gillespie & Associates, Inc.
BOE is defined as barrel of oil equivalent, determined using a ratio of six MCF of natural gas equal to one barrel of oil equivalent.
IP (BO/d or BOE/d) (24 hour rate) is defined as the peak oil volume produced on a daily basis through permanent production facilities
that occur within the first few days of initial production from the well.
EUR estimates do not necessarily represent reserves as defined under SEC rules and by their nature and accordingly are more
speculative and substantially less certain of recovery and no discount or risk adjustment is included in the presentation. Actual
locations drilled and quantities that may be ultimately recovered from the Company’s interests could differ substantially.
