Certain matters discussed in this report, excluding historical information,
include forward-looking statements - statements that discuss the Company's
expected future results based on current and pending business operations.  The
Company is making these forward-looking statements in reliance on the safe
harbor protections provided under the PRIVATE SECURITIES LITIGATION REFORM ACT
OF 1995.

Forward-looking statements can be identified by words such as "anticipates,"
"believes," "expects," "planned," "scheduled" or similar expressions.  Although
the Company believes these forward-looking statements are based on reasonable
assumptions, statements made regarding future results are subject to numerous
assumptions, uncertainties and risks that may cause future results to be
materially different from the results stated or implied in this document.
Important risk factors (but not necessarily all important factors) that could
cause actual results to differ materially from those expressed in any forward-
looking statement made by, or on behalf of, the Company would include, but in no
way be limited by, the Company's ability to obtain agreements with co-venturers,
partners and governments; its ability to engage drilling, construction and other
contractors; its ability to obtain economical and timely financing; geological,
land, sea or weather conditions; world prices for oil, natural gas and natural
gas liquids; adequate and reliable transportation systems; and foreign and
United States laws, including tax laws.  Additional information about issues
that could lead to material changes in performance is contained in the Company's
Form 10-K.

NOTE 4 - MERGER WITH SOUTHERN MINERAL CORPORATION:

     PetroCorp completed the acquisition of Southern Mineral on June 6, 2001.
Southern Mineral shareholders could elect to receive .471 shares of PetroCorp
common stock or cash of $4.71 or some combination thereof for each share of
Southern Mineral common stock they owned. Based on elections of Southern Mineral
shareholders, PetroCorp issued 4 million shares (valued at approximately $39
million) and paid cash of approximately $21.2 million. The cash consideration
includes cash due to warrant and option holders, net of cash received from the
exercise of Southern Mineral warrants and options. The totals do not reflect
800,336 shares of Southern Mineral purchased by PetroCorp in open market
transactions prior to the merger for $3.4 million. THE FOLLOWING INFORMATION IS
BASED ON A PRELIMINARY ANALYSIS OF THE TRANSACTION AND IS SUBJECT TO CHANGE WHEN
THE FINAL ANALYSIS IS COMPLETE.

     The acquisition of Southern Mineral was accounted for using the purchase
method of accounting as of June 1, 2001 because as of that date, the company had
effective control, and the results of operations have been included since that
date. The purchase price allocation is (amounts in thousands):

NOTE 6 - HEDGING ACTIVITIES:

     On June 15, 1998, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS 133, as amended, requires that all
derivative instruments be recorded on the balance sheet at their fair value.
Changes in the fair value of derivatives will be recorded each period in current
earnings or other comprehensive income (only certain types of hedge transactions
are reported as a component of other comprehensive income). Additionally, for
all hedging transactions the nature and type of hedge will be disclosed. The
Company adopted SFAS 133 in January 2001.

     To reduce the impact of fluctuations in the market prices of oil and
natural gas, the Company periodically utilizes hedging strategies such as
futures transactions or swaps to hedge the price of a portion of its future oil
and natural gas production. Results of these hedging transactions are reflected
in oil and natural gas sales in the month of the hedged production.

     In the first quarter of 2000, the Company entered into swap transactions in
an effort to lock in a portion of higher oil prices. These transactions applied
to approximately 50 percent of the Company's projected oil production from April
2000 through December 2000, at prices ranging from $23.57 to $29.00 per barrel.
Oil and gas revenue includes $69,000 received and $434,000 in settlement of swap
transactions through September 30, 2000. In the second quarter of 2000, the
Company entered into a no-cost collar arrangement by which 180,000 MMbtu for
each of the months July through October 2000 were subject to a $4.96 ceiling and
a $3.50 floor per MMbtu. The Company determined that the estimated fair value of
the outstanding hedges at September 30, 2000 was not significant.

     As part of PetroCorp's acquisition of Southern Mineral Corporation
("Southern Mineral"), the Company assumed crude oil and natural gas costless
collars which have the following outstanding at September 30, 2001:

     Based on September 30, 2001 prices, a 10% change in oil and gas prices will
not cause the Company's obligation under the costless collars to have a material
adverse effect on the financial position or results of operations of the
Company. Hedging transactions for the three and nine months ended September 30,
2001 reduced oil and gas revenues by $16,000 and $45,000, respectively
(reclassified from comprehensive income). The estimated fair value at September
30, 2001 of the crude oil and natural gas collars was a receivable of $704,000.

                                       7


     The Company offsets any gain or loss on the swap and collars contract with
the realized prices for its production. While the swaps and collars reduce the
Company's exposure to declines in the market price of natural gas and oil, this
also limits the Company's gains from increases in the market price.

     As a result of the merger with Southern Mineral, the Company assumed an
interest rate swap position that was originally intended to hedge the
variability of interest expense associated with Southern Mineral's variable rate
Canadian debt. Under the swap agreement, the Company receives a floating rate of
the Canadian prime rate and pays a fixed rate of 5.96% on a notional amount of
Canadian $15 million. The interest rate swap does not qualify for hedge
accounting at September 30, 2001 and the Company has recorded the swap's fair
value of $192,000 as a liability at the date of the merger. The estimated fair
value at September 30, 2001 is a liability of $423,000.

     These values include the preliminary allocation of the purchase price of
Southern Mineral and are subject to change. See Note 8.

     As more fully described in the Company's 10-K, PetroCorp utilizes the full
cost method of accounting for costs related to its oil and natural gas
properties. Under this method, capitalized costs are subject to a ceiling test,
evaluated each quarter, which limits such pooled costs to the aggregate of the
present value of future net revenues attributable to proved gas and oil reserves
discounted at 10 percent plus the lower of cost or market value of unproved
properties. At September 30, 2001, the Company's unamortized costs of oil and
gas properties exceeded this ceiling amount by approximately $20 million due to
low gas prices in effect on that date. The cash spot price for natural gas in
the US and Canada was $1.86 and $1.18, respectively, on September 30, 2001.
However, due to the subsequent recovery in the market prices for natural gas the
Company was not required to record a write-down of its oil and gas properties. A
decline in gas and oil prices from current levels, or other factors, without
other mitigating circumstances, could cause a future write-down of capitalized
costs and a non-cash charge against future earnings.

NOTE 8 - LONG-TERM DEBT:

     In July 2000, the Company entered into a $75 million revolving credit
agreement with the Toronto-Dominion Bank (TD Bank), the agent, and the Bank of
Nova Scotia. The term of the facility is through April 30, 2003 and the initial
borrowing base was set at $58 million. Borrowings can be funded by either
Eurodollar loans or Base Rate loans. The interest rate on the borrowings is
equal to an interest rate spread plus either the Eurodollar rate or the Base
Rate. The interest spread is determined from a sliding scale based on the
Company's borrowing base percentage utilization in effect from time to time. The
spread ranges from 1.25 to 2.25 on Eurodollar loans and .25 to 1.25 on Base Rate
loans. At September 30, 2001, the weighted average interest rate under this
facility was approximately 6.7%.

                                       8


     The $75 million revolving credit agreement prohibits the declaration and
payment of dividends on the common stock of the Company.  Also, the debt
agreement requires the Company to maintain a minimum current ratio, a minimum
tangible net worth, and a minimum interest coverage ratio.

     As a result of the merger with Southern Mineral, the Company assumed
Southern Mineral's outstanding debt of $11.3 million subject to a US credit
facility with Bank One and $1.3 million subject to a Canadian loan facility with
the Canadian branch of the same lender. At the time of the merger, PetroCorp
obtained loan waivers which reduced the facility amounts to $15 million subject
to the US facility and C$3 million under the Canadian facility. The Company paid
off outstanding debt and closed these facilities in the third quarter of 2001.

NOTE 10 - RECENT ACCOUNTING PRONOUNCEMENTS:

     In June 2001, the Financial Accounting Standards Board ("FASB") issued FAS
No. 141 and 142. FAS No. 141, Business Combinations, requires the purchase
method of accounting be used for all business combinations initiated after June
30, 2001. FAS No. 142, Goodwill and Other Intangible Assets, changes the
accounting for goodwill from an amortization method to an impairment-only
approach and will be effective January, 2002. The Company believes that adoption
of these new standards will not have an effect on its results of operations or
its financial position. In June 2001, the FASB issued FAS No. 143, Accounting
for Asset Retirement Obligations, and in August 2001, FAS No. 144, Accounting
for Impairment or Disposal of Long-Lived Assets. Management is currently
evaluating the impact of FAS 143 and 144 on financial position and results of
operations.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations.

General

     The Company's principal line of business is the production and sale of its
oil and natural gas reserves located in North America. Results of operations are
dependent upon the quantity of production and the price obtained for such
production. Prices received by the Company for the sale of its oil and natural
gas have fluctuated significantly from period to period. Such fluctuations
affect the Company's ability to maintain or increase its production from
existing oil and gas properties and to explore, develop or acquire new
properties.

     The following table reflects certain operating data for the periods
presented:

Results of Operations

Three Months Ended September 30, 2001 Compared to Three Months Ended September
30, 2000

     Overview. The Company recorded third quarter 2001 net income of $3,049,000,
or $0.24 per share. This compares to net income of $3,264,000 or $0.38 per share
recorded in the third quarter of 2000. The decrease in net income results from
lower oil and gas prices offset by volume increases primarily due to the merger
with Southern Mineral. Net cash provided by operating activities was $4.2
million for the quarter ended September 30, 2001 compared to net cash provided
of $9.6 million for the corresponding quarter of 2000.

     Revenues. Total revenues increased 17% to $13.8 million in the third
quarter of 2001 compared to $11.8 million in the third quarter of 2000,
primarily due to volume increases associated with the merger with Southern
Mineral. The Company's natural gas production increased 11% to 2,607 MMcf from
2,342 MMcf and oil production increased 91% to 189 MBbls from 99 MBbls,
resulting in the Company's overall equivalent production increasing 27% to 3,741
MMcfe from 2,936 MMcfe. The increase in oil and gas production is primarily due
to the merger with Southern Mineral as well as several new wells coming on-line
in Canada.

     The Company's composite average oil price decreased 7% to $23.71 per barrel
in the third quarter of 2001 from $25.50 per barrel in the third quarter of
2000. The Company's average U.S. natural gas price decreased 38% to $2.55 per
Mcf in the third quarter of 2001 from $4.13 per Mcf in the prior year quarter,
while the average Canadian natural gas price increased 25% to $3.81 per Mcf in
the third quarter of 2001 from $3.06 per Mcf for 2000. Increased volumes from
the merger with Southern Mineral, offset by price decreases, resulted in a 17%
increase in oil and gas revenues to $12.9 million in the third quarter of 2001
from $11.0 million in the prior year.

     Production Costs. Production costs increased 67% to $4.0 million in the
third quarter of 2001 as a result of the costs associated with the additional
wells acquired in the merger with Southern Mineral and increased production
taxes related to higher commodity prices. Production costs per Mcfe increased by
29% to $1.06 per Mcfe in the third quarter of 2001.

     Depreciation, Depletion & Amortization (DD&A). Total DD&A increased 60% to
$4.0 million in the third quarter of 2001.  The composite oil and gas DD&A rate
increased 30% to $0.92 per Mcfe from $0.71 per Mcfe.  This reflects the impact
of the Southern Mineral acquisition and previously unevaluated properties
evaluated in late 2000 and moved to the full cost pool.

     General and Administrative Expenses. General and administrative expenses
increased 73% to $739,000 in the third quarter of 2001 from $428,000 in the
third quarter of 2000 as a result of costs associated with the transition of
processing from and the shut down of Southern Mineral offices.

     Investment Income.  Investment income decreased 88% to $17,000 in the third
quarter of 2001 from $147,000 in the third quarter of 2000 due to excess cash
being used to pay down debt.

     Interest Expense. Interest expense increased 2% to $832,000 in the third
quarter of 2001 from $813,000 in the prior year quarter, reflecting additional
debt associated with the merger with Southern Mineral offset by lower interest
rates. The Liquidity and Capital Resources section further describes changes in
debt.

     Other Income. Other income includes a $0.6 million realized translation
gain on the short-term investment of Canadian assets in US dollar denominated
accounts during the third quarter of 2001.

     Income Taxes. The Company recorded a $1,942,000 income tax expense with an
effective tax rate of 39% on a pre-tax income of $4,991,000 in the third quarter
of 2001.  This compares to an income tax expense of $2,597,000 with an effective
tax rate of 44% on pre-tax income of $5,861,000 million in the third quarter of
2000.

Nine Months Ended September 30, 2001 Compared to Nine Months Ended September 30,
2000

     Overview. The Company recorded a first nine months 2001 net income of
$11,854,000, or $1.14 per share. This compares to net income of $7,104,000, or
$0.82 per share recorded in the first nine months of 2000. This improvement
results from higher oil and gas prices and volume increases primarily due to the
merger with Southern Mineral. Net cash provided by operating activities was
$16.7 million for the nine months ended September 30, 2001 compared to $17.6
million for the corresponding nine months of 2000.

     Revenues. Total revenues increased 40% to $40.3 million in the first nine
months of 2001 compared to $28.7 million in the first nine months of 2000,
primarily due to volume increases from the merger with Southern Mineral. The
Company's natural gas production increased 9% to 6,702 MMcf from 6,129 MMcf and
oil production increased 32% to 416 MBbls from 314 MBbls, resulting in the
Company's overall equivalent production increasing 15% to 9,198 MMcfe from 8,013
MMcfe. The increase in natural gas production is primarily the result of the
merger with Southern Mineral as well as several new wells coming on-line in both
Canada and the US. The increase in oil production also reflects the merger with
Southern Mineral.

     The Company's composite average oil price decreased 7% to $24.91 per barrel
in the first nine months of 2001 from $26.72 per barrel in the first nine months
of 2000. The Company's average U.S. natural gas price increased 19% to $4.08 per
Mcf in the first nine months of 2001 from $3.43 per Mcf in the prior year, while
the average Canadian natural gas price increased 56% to $4.09 per Mcf in the
first nine months of 2001 from $2.62 per Mcf in 2000. The significant increase
in gas prices, as well as the increased production volumes, resulted in a 41%
increase in oil and gas revenues to $37.7 million in the first nine months of
2001 verses $26.8 million in the prior year nine months.

     Production Costs. Production costs increased 38% to $8.4 million in the
first nine months of 2001 as a result of additional wells acquired in the merger
with Southern Mineral. Production costs per Mcfe increased 19% to $0.92 per Mcfe
in the first nine months of 2001 from $0.77 in the same nine months of 2000.

     Depreciation, Depletion & Amortization (DD&A). Total DD&A increased 37% to
$9.2 million in the first nine months of 2001 from $6.7 million in the first
nine months of 2000. The composite oil and gas DD&A rate increased 23% to $0.86
per MMcfe from $0.70 per MMcfe. This reflects the impact of the Southern Mineral
acquisition and previously unevaluated properties evaluated in late 2000 and
moved to the full cost pool.

     General and Administrative Expenses. General and administrative expenses
increased 24% to $1,729,000 in the first nine months of 2001 from $1,389,000 in
the first nine months of 2000 as a result of costs associated with the
transition of processing from and the shut down of Southern Mineral offices.

     Restructuring Costs. The Company recorded a $0.5 million credit against
restructuring costs in the first nine months of 2000 primarily because the
Houston office space was leased to an outside party and the Company's obligation
ended.

     Investment Income. Investment income decreased 79% to $111,000 in the first
nine months of 2001 from $524,000 in the first nine months of 2000 due to lower
interest rates and excess cash being used to pay down debt.

     Interest Expense. Interest expense decreased 47% to $1,500,000 in the first
nine months of 2001 from $2,831,000 in the prior year first nine months,
reflecting the impact of rate decreases and lower debt levels over most of the
period. The Liquidity and Capital Resources section further describes changes in
debt.

     Income Taxes. The Company recorded a $7,972,000 income tax expense with an
effective tax rate of 40% on pre-tax income of $19.8 million in the first nine
months of 2001. This compares to an income tax expense of $5,296,000 with an
effective tax rate of 42% on pre-tax income of $12.6 million in the first nine
months of 2000.

Liquidity and Capital Resources

     As of September 30, 2001, the Company had working capital of negative $4.2
million as compared to positive $9.0 million at December 31, 2000. Net cash
provided by operating activities was $16.7 million for the nine months ended
September 30, 2001 compared to $17.6 million for the corresponding nine months
of 2000.

     The Company's total capital expenditures were $71.5 million ($32.9 million
cash expenditure), which includes the Southern Mineral acquisition, and $6.0
million for the nine months ended September 30, 2001 and 2000, respectively,
primarily related to the acquisition of Southern Mineral in 2001 and exploration
and development in both years.

     No sales of oil and gas properties occurred in the first nine months of
either 2001 or 2000.

     In July 2000, the Company entered into a $75 million revolving credit
agreement with the Toronto-Dominion Bank (TD Bank), the agent, and the Bank of
Nova Scotia. The term of the facility is through April 30, 2003 and the initial
borrowing base was set at $58 million. Borrowings can be funded by either
Eurodollar loans or Base Rate loans. The interest rate on the borrowings is
equal to an interest rate spread plus either the Eurodollar rate or the Base
Rate. The interest spread is determined from a sliding scale based on the
Company's borrowing base percentage utilization in effect from time to time. The
spread ranges from 1.25 to 2.25 on Eurodollar loans and .25 to 1.25 on Base Rate
loans. At September 30, 2001, the Company had a total of $36.6 million
outstanding under the revolver and $21.4 million available based on the current
borrowing base, as defined, subject to certain limitations. During the first
nine months of 2001, the average interest rate under this facility was
approximately 6.9%.

     The Company has historically funded its capital expenditures and working
capital requirements with its cash flow from operations, debt and equity capital
and participation by institutional investors. If the Company increases its
capital expenditure level in the future or operating cash flow is not as
expected, capital expenditures may require additional funding, obtained through
borrowings from commercial banks and other institutional sources or by public or
private offerings of equity or debt securities.

Merger with Southern Mineral

     As indicated in Note 4 to the financial statements, PetroCorp completed its
merger with Southern Mineral Corporation on June 6, 2001. Funds needed to
complete this transaction were provided by cash on hand and borrowings under
existing lines of credit. As a result of the merger with Southern Mineral, the
Company assumed Southern Mineral's outstanding debt of $11.3 million subject to
a US credit facility with Bank One and $1.3 million subject to a Canadian loan
facility with the Canadian branch of the same lender. The Company paid off all
Bank One loans during the third quarter by utilizing the existing TD Bank credit
facility. The Bank One credit facilities were terminated during the third
quarter.

Common Stock Repurchases

     On September 14, 2001, the Company announced that the Board of Directors
authorized the purchase of up to 1,000,000 shares of the Company's stock.
Through October 31, 2001, 334,470 shares have been purchased at a cost of
$2,972,000.

Other

     In June 2001, the Financial Accounting Standards Board ("FASB") issued FAS
No. 141 and 142. FAS No. 141, Business Combinations, requires the purchase
method of accounting be used for all business combinations initiated after June
30, 2001. FAS No. 142, Goodwill and Other Intangible Assets, changes the
accounting for goodwill from an amortization method to an impairment-only
approach and will be effective January, 2002. The Company believes that adoption
of these new standards will not have an effect on its results of operations or
its financial position. In June 2001, the FASB issued FAS No. 143, Accounting
for Asset Retirement Obligations, and in August 2001, FAS No. 144, Accounting
for Impairment or Disposal of Long-Lived Assets. Management is currently
evaluating the impact of FAS 143 and 144 on financial position and results of
operations.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

     The Company's primary sources of market risk are from fluctuations in
commodity prices, interest rates and exchange rates.

Commodity Price Risk

     The Company produces and sells natural gas, crude oil, condensate, natural
gas liquids and sulfur. As a result, the Company's financial results can be
significantly affected as these commodity prices fluctuate widely in response to
changing market forces. The Company has previously utilized hedging transactions
to manage its exposure to price fluctuations on its sales of oil and natural
gas.

     As detailed in Note 6 to the financial statements, the merger with Southern
Mineral resulted in PetroCorp assuming crude oil and natural gas costless
collars. Based on September 30, 2001 prices, a 10% change in oil and gas prices
will not cause the Company's obligation under the costless collars to have a
material adverse effect on the financial position or results of operations of
the Company. The impact of hedging transactions for the nine months ended
September 30, 2001 was a reduction of oil and gas revenues by $45,000. The fair
value at September 30, 2001 of the crude oil and natural gas collars was a
receivable of $704,000.

Interest Rate Risk

     As a result of the merger with Southern Mineral, the Company assumed an
interest rate swap position that was originally intended to hedge the
variability of interest expense associated with Southern Mineral's variable rate
Canadian debt.  Under the swap agreement, the Company receives a floating rate
of the Canadian prime rate and pays a fixed rate of 5.96% on a notional amount
of Canadian $15 million.  The interest rate swap does not qualify for hedge
accounting at September 30, 2001 and the Company has recorded the swap's fair
value  of $192,000 as a liability at the date of the merger.  The estimated fair
value at September 30, 2001 is a liability of $423,000.
